My 6 year old has been learning about trees at school, and had questions for me. Needless to say, she now has the best understanding of data structures in her class, and I expect parents evening will be "interesting"8

Tips for people new to programming
1. Start counting from zero
2. Trees are upside down, root's probably at the top
3. Warnings are usual, go rogue!
What more? 😂35 -
So I was with my friends on the subway and we were talking about an assigment we have due this week with trees in Java. I got to say, the face on the old ladie next to us when we said "we must kill all the children left in the tree" was just epic! She must thought we were talking about beating some little kids or something... 😅3

1. If your contract allows it (and it should), get more involved in public dev community. Your employer benefits greatly from making a small closed source core product, with a giant open source ecosystem around it. Write public articles. Working in a community larger than one single business is fun.
2. Start a company coding club, a "labs" division, work in a slightly more exotic language. Great if your employer gives you time, but using some of your own is worth it too. Work on non critical tools, creative experiments. Sometimes you stumble onto incredibly valuable ideas which would never have popped up if you had strictly followed stakeholder requirements.
3. Listen to your body. If you feel restless, go for a run. If you feel tired, take a nap. If you're stuck, wander around the company. If you feel down, go find a place with more than a dozen trees. And always have a notepad nearby for doodling!5 -
Had to wirte and optimize a C++ program that finds for 1000x1000x1000 grid points the 100 nearest points for each (with an additional factor to make it more complicated).
It had to run in under 18 minutes to pass. No matter what I did I couldn't get it fast enough. I tried kd-trees, caching of certain points, optimizing distamce calculations by ommiting any irrelevant factor, saving points' calculated squares etc etc. When Ibwas down to 20 minutes, I realized, that my makefile had an error and ignored the - O3 flag...
Well, it actually ran 5 minutes with -O3.10 -
I stare through the blueish black backgrounds and blurry colorful syntax into a somewhat familiar office within a mirrored world. That damned reflective glass layer covering these meaningless pixels is certainly not on my side.
The rushing sound of transactions flowing through cables is silenced today. Some blood cloth in the invoicing system is zeroing out everything after the currency mark.
While sighing I spin a one-and-a-half pirouette on my desk chair — even when desperate, you shouldn't give up on style — I take three steps away from my screen and try to harmonize my thoughts.
So much noise, everywhere... Noise from within?
I have been stuck at the apogee of an inhale for a while now. Locked into some masochistic constriction, self-punishment for the blindness which stings my ego.
Just fucking take a deep breath you asshole...
I freeze in place, and fall backwards.
Patterns on the creamy drywall rapidly vibrate and synchronize on vivid rhythms of respiration and resonating basslines. Deep indigo rainbows ripple through tiny veins, in-between chalky grains, raining as fine magenta dust through the ceiling frames.
My bare feet slide over soft oscillating concrete, fine flows of unsievable sand surrounded by toes, toes surrounded by streaming variables veiled in obscure vile abstractions.
A jadegreen field of vectored compressions resiliently rumbles and bounces through the clearances and corners of the vibrant concrete office cave, whispering in tongues. I try to voice my woes in little blips and bleeps but I seem to be missing an asymmetric key to their shrouded sequenced speech.
Suddenly, a wild turbulence breaks up all signals.
Joanna floats by in her tipsy effervescent cloud of disordered black hair and alcohol perfume, one hand grasping grapes, her other waving at me.
With every finger she moves a thousand tensors propagating paradoxically flawed but perfect pieces of an intricate surreal picture, sketching whole constellations of possible paths throughout the leafs of the giant Ficus next to her desk.
She stops dead in her tracks, and asks somewhat hypocritically: "Are you high?"
I can not discern the meaning of her words, and respond stoically.
"Joanna! Check out those branches!".
"Pun intended?", she giggles.
I'm focused on her grapeless hand, her fingers stretching to reach the lush little tree.
On touch, the plant shivers, grappled in the tight net of the puppet master. She pulls her strings, applying measured weights, all nodes normalize, and Joanna speaks in an oddly soft tone:
"Isn't it beautiful, how so many models emulate nature"
Her cheek buried in foliage she babbles on about unbalanced search trees and machine learning models... but from the tips of her fingers tables and indexes flow into the plant. Users, payments, tariffs, invoices and taxes crawl over the bark, joining at thicker branches, joining at the stem....
Joining. JOINING. A JOIN.
"IF THERE'S NO FUCKING TAX MULTIPLIER IN THIS LEFT JOIN, EVERYTHING COALESCES TO ZERO" I shout at a perplexed Joanna who squeezes grape juice over her desk. I hop on the beat to my keyboard. She looks puzzled, hugs her Ficus tightly, and reaches for the whiskey bottle behind her monitor.
Attracted by my exclamation, Tom from finance swings open the door, while I push my branch.
I look at Joanna still half hiding between the leaves, and I laugh at her: "Branches! Oh, lame, I finally got it!"
Tom's heavy voice interrupts me: "Does this mean... does this mean that the invoicing bug is resolved?".
I smile at Tom with his tailored suit and waxed hair. "The money is flowing once more. All debts are being settled."
He releases his breath in relief, which he seems to have held since that morning as well.
Joanna adds: "Although I think he is forever indebted to my Ficus".
I nod.14 -
I really love my job these cold, rainy autumn days with yellow trees, where I can work from home having a nice fire going in the fireplace and the dog sleeping on my feet :-)

So the tax authorities in the Netherlands have this slogan that roughly translates to:
"We can't make it fun, but we can make it easier."
I'm not sure how this is going to be easy for me. This arrived in the mail today.
Even worse this is a fuck up from them. They are saying our company did not do it's taxes but when we log in their online portal we can see that we did them. But they are saying that they don't see it in their system.
Who build that system?
Trying to stay calm when they are claiming I own them more taxes then my company has earned in a year.
I did not have enough sleep for this drama.
By the way how about we save some trees and don't send 30 letters on 1 day.

Running an Alpaca farm in rural Finland, next to some mountain creek with an oldschool water mill so I can grind flour and coffee beans.
I hated people so I tried to find solace as a nerd in technology, but tech is also fucking awful so I feel like retiring in a tranquil forest with some equally grumpy wooly animals.
If I get eaten by a bear because I'm a skimpy city boy that's OK, more epic than being found decomposing slumped over on a keyboard in the boring grey suburbs.
All of this is probably pandemic-me talking though. So sick of this concrete city with the farting cars and fat obnoxious shoppers.
I need some trees around me, and some mammals with a higher IQ than my current neighbors.9 -
Christmas.
The only time where computer scientists and other people agree how trees are shaped.
Now we only need to convince them that the tip is in fact the root.2 -
I once reviewed a Pull Request made by a fairly junior developer. They had joined recently, and this was one of the first times they had to touch a bigger part of the code.
Due to a mix of inexperience, new (to them) coding standards and lack of git knowledge, they ended up with a mess of a PR, with a few thousand lines changed, and no way to split it off.
I ended up spending the best part of a day reviewing the whole thing and requesting changes.
Even with the long list of improvements, however, I wasn't sure they would get the magnitude of their fuckup.
So I decided to use a real-world, palpable way to show them what they had done: I went and printed the github diff for that PR. It rendered the glorious amount of 73 pages.
I'll never forget their face, and those of their teammates, when I barged into the room with a thick wad of paper and deposited them on their desk.
At least it worked. I never saw another big, ill-thought pull request from them again.3 -
My mom was not aware of the "forward" option in mails for many years. If she needed to forward documents, she would print them from the original mail, scan them to her computer, and attach the scanned files to a new mail.
She also didn't realize she can just save them on her computer, in case she didn't want to forward the entire correspondence, but only the documents.
I'm so sorry trees, I didn't know 😂4 -

*The interview wasn't off to a good start, as the recruiter forgot he invited me for an interview, so he just led me to some empty office after letting me wait for good 15 minutes. *
Them: Here, write some pseudocode to find a value in a tree.
Me (thinking): Interesting question; DFS / BFS would be really simple here, but nobody uses trees for that - perhaps I should ask about characteristics of the tree in question?
But before I realised, the interviewer already rushed out the office, so I just picked up my jacket and left... -
1. My senior told me that my code is crashing.
2. I check the code and told him that it is not my doing. As there was lots of nested if-else as I prefer to keep a variable and update it in if conditions. Like a filters rather than trees with branches. What I say, I knew my coding style.
3. Then he show me my git commit and I am having existential crises.
Am I missing days? How can I? I mean was I abducted and in mean time some alien took my place and they placed this memory of me coding?
Ah! man I think I am possessed by some inexperienced developer. I seriously need some fucked up crash to exorcise him.3 -

Just because you can learn HTML in a day doesn’t mean that you don’t need a degree.
Did you know that your browser, HTML, CSS, Javascript, and even your operating system use linked lists, binary trees, hash tables, and other so-called “useless” data structures?
It’s important to understand the roots and fundamentals of computer science even if you won’t use that knowledge day to day.
It changes your perspective on programming once you learn what actually goes on under the hood, and makes you think twice about the impact of what you write.
It’s relatively easy to get a programming job without a degree nowadays, but it often leads to web developers claiming that degrees aren’t important to their web apps.
There is much more than just the web to computer science, and that’s something to always keep in mind.10 -
A friend asked if I could take a look at the function, which he wrote, to see if two trees are equal.
The chat conversation:
F: I sent code.
Me: *put eye on "flag and && true"
F: Hey?
F: You are there?
F: All right?!
A few hours later...
Me: Each time this function is executed, a programmer dies. Goodbye.
And so it's over.

Was interviewed some 15 years ago while quite fresh out of university. Huge panel of people hammering away with questions so after an afternoon in the room all my fried brain could come up with when they asked if I had any other interest was "...trees..." :)

Teacher: You should plant trees at least on your birthdays. Go green.
Me: I do it daily Sir! Check my Github, its really green.

*One day at office sitting at my desk coding in front of a window with a refreshing breathe of fresh air coming from it, and a decent view of trees in front of the building*
CEO: would you like to be sitting together with the other dev?
Me: that would be awesome!
- next day -
*come to work to see my stuff has been moved over next to the always open door, with clear view of the lobby, prone to all kinds of nonstop distractions, and psychologically lethal ambiance*
ceo: YOU TWO ARE SITTING TOGETHER NOW, AREN'T YOU PSYCHED??
me: WELL CANT SAY PSYCHED, BUT A PSYCHO SOON HAHAHA >fucking asshole<4 -
It came to me, a brilliant idea, a simple solution to an everyday problem and easy route to market. Great, starts looking for domains and writes down idea in full in case i forget. Later that day, picks up 12 year old son from school, tells him my great idea. He told me how shit it was and why straight away.5

Brilliant idea time:
Inspired by @TrojanMorse and his fractal trees
A fractal tree wallpaper that grows throughout the day.
So at 12 a script starts a new fractal and only uses depth 1 (a twig). Then every other hour it branches once more so at 2 am the fractal would have depth 2 and at noon it would have depth 7. That way you get a tree growing throughout the day for your screensaver. Now to make this a thing13 -
On the game front, I see so much conflicting advice. "Start getting feedback" as soon as possible. "Donnt soft launch on steam! The algol will wreck you.", "soft launch on itch to get feedback", "dont soft launch on itch!"
"Start marketing today", "focus on influencers", "get to know communities *before* you advertise", "dont get to know communities beforehand if you're just planning on self prompting", "dont self promote".
"CPM is important.", "CPA is important". Etc.
Sounds a lot like "have a bunch of money upfront." The solution is just to succeed from the start! It's so obvious. Just invent the next gta. The next facebook. Get a small loan of 50,000 dollars, or a million. Donate for a year to other kickstarter projects so people will know you and reciprocate! But also dont ebeg!
How about no. How about fuck all this advice by silver spoon assholes that didnt have to work on shoestring budgets. The advice is the equivalent of having a 300 page tonedeaf book, every page blank except page 150, where the words "fuck you. I got mine." Are printed in times new Roman, 14pt font, neatly in the center of the page.
The truth is most of the "indies" already made it in the software industry proper, before switching over. $5k kickstarter videos, with $15k marketing budgets, no doubt funded in part through their own money funneled through services that provide shell donations, because KS is being used as a glorified advertising service. People buying off steam curators for promotions, youtubers making sponsored videos without disclosing they're sponsored. Fake viralility. Fake campaigns. Predetermined success for those who could *already* afford to develop and go commercial without a publisher. And they came into the market and cannibalized the opportunity, raising the bar for everyone that wasnt them. I guess that's actually a good thing, because we wouldnt have half the amazing games we do, and the pressure to produce quality. But then I see fantastic games utterly ignored or flailing in an attempt to compete for eyeballs in an industry frequently dominated by gatekeeping marketeers and influencers, where human grace determines success or complete oblivion. And I'm just disgusted with it.
Also buy my game. Preorder NOW! And you'll get a REAL canvas bag, I'll go to like the goodwill and buy one and screen print the game logo on it or some shit. Buy the special collectors edition and get pictures of my feet. Buy the game of the year edition and get a real gasmask. Preorder now and I'll fucking suck your di k right now. No lie. Preorder the diamond edition RIGHT NOW in the next six minutes and I will send you one hundred thousand dollars in gold plated bottle caps. Limited supply. one million per customer. Offer expires soon. This is not a scam. I repeat. This is NOT a scam.
In other news I'm soft launching Atom Ranger in six months (assuming the nuclear apocalypse hasn't *actually* started by then). Its state of decay and fallout meets rimworld. Build and manage a sprawling base, resolving conflicts, exploring post apocalyptic Colorado and surrounding territories of no-mans-land. Navigate hazardous weather, radioactive terrain, collapsed bridges, dangerous rivers, and deal with cultists, bandits, slavers, and hungry cannibals. Broker peace between not just the factions outside your settlements, but within your base too. Manage conflicts, settle disputes, avert disasters, barter, scavenge, and survive in a fully dynamic world, where buildings slowly crumble, grass and trees sprout up in the road and vacant lots, fires burn out of control, and factions loot, ruin, and takeover settlements. Watch the world and the survivors in it change and survive. Help them to survive, or become a warlord and rule over the wastes.
Lets be honest. It's basically kenshi but less complicated.
If you want to volunteer to test (instead of paying to be a glorified tester, aka "alpha") let me know in the comments.
I'm currently setting up a discord and mailing list.28 -
Waking up from a dream with a girl in it.
TL;DR: We fell in love and I can finally somehow remember her. Not completely though...
(To the perverts: We did not have sex nor did we kiss.)
The worlds I am becoming a part of are very complex. I won't get into the details of how they look like. I will tell as far as I can remember.
<vaguely remember the beginning>
My sister, my mom and I went into a house which turned out to have weird things inside.
Suddenly I became something like an agent and I had a special mission. I went to the basement of this building. Saw a few guys chilling there. Grabed a walkie talkie which was taped on the right wall. I have listened to it while moving back to the entrance, when I have arrived there, it began to do disortion type of sounds.
<I have been to a lot of different places here. Telling each of them would make me to not come to an end lol>
Then I have decided to go outside. The outside-of-the-house world changed. I was at floor 8 or something like that. It was very high when I looked down. All of the sudden I got into a waterfall type of thing which was about to suck me in to a circle. The waterfall was limited to the area of where this house was. It was basically hovering above the streets, but never reaching the streets.
I somehow met the lovely girl in a cube type of thing that helped us not to fall down through the spiral. We enjoyed the action the waterfall created. It made us move in a circle and we had to hold ourselves at the wall of the cube which luckily had knobs to hold on.
After that whole action I have been in my bed and sleeping. She somehow found me on a social media platform and contacted me with "Meet me on <some strange date>".
<some unlogical world shit happens here. I will just skip them until the date>
The day to meet her comes. She is up on a hill with a "purple?<idk it was purple-ish>" sky.
<can not remember the dialogue>
We had a great time and I felt that she had feelings for me.
She then went away. What about me? And me, too. ;)
The next day I went to see her again. She was gone. I found out that she has a brother. I talked to him about where she might be. Turns out her brother was a demon or satan <idk they all became agressive and god-like powerful lol>.
He told me that she must be there where <random name of enemy> is to fight the enemy to rescue her mom.
Her brother went to help her. I followed him since I did not know where the enemy was. Let alone where I was. The world has changed for the 99999th fucking time lol.
I followed him up another hill with trees and a lot of people. It was autumn.
Then we found her sitting on a hill looking down to the sea beneath us with cherry blossom trees around her.
The dream was about to end. I felt it. So I have asked her a few questions after the happy greeting, but I can not remember them and her answer anymore. But I do remember that she did not say anything after one question. She just stared at me looking through my eyes which immediately did end the dream.
I was able to get into the dream shortly after it a few times, but I was not able to interact with them.
Besides of that: I have had "Battle Symphony-Linkin Park" playing as a background music for the whole dream a long.
The good thing is that I somehow would be able to recreate her. I know how she looks like to about 60%.
I do not even know why the fuck I am telling y'all this.3 -
For those keeping track of what inwas doing here: https://devrant.com/rants/1641742/...
Inhave been playing around woth fractals and making trees (although it wasnt 3 dementional) i have been taking time to learn things there regardless and had an attempt at making a landscape using Perlin noise procedurally generated by the computer
I am planning on releasing the code as soon as i figure out making these trees geberate at certain points of the land and firstly, make it branch in a 3 dementional space
Update of the land
Although i dont have the most time to so this and had to learn java in the process to move away from the limitations i had in the browser. It is a fun experiance and good break away from my actual job.
Ill see how it goes while working on this
✌

It's a beautiful autumn day. The sun is out, the sky is blue, it's warm and the trees' leaves are already colored magnificently.
What will I do today? - Exam preparation! :D3 -
Prior post on this story: https://devrant.com/rants/1635258/...
Apparently my dad decided to adopt the Windows file system hierarchy for his business.
He has managed to store his video, picture, and music folder INSIDE the DOCUMENTS folder. And there are seperate video, picture, and music folders outside of this folder. The business information is in all of these folders adding up to about 600GB of data in 10 different folders and 4 trees. Nothing has been deleted since 2010. WHAT IN THE EVER LOVING CHRIST ON A FUCKING POGO-STICK IS THIS ABOMINATION. I AM GOING TO JUMP OFF A CLIFF NAKED AND ON FIRE BEFORE I TRY TO SORT THIS SHIT.

I'm usually nice to people and try to look for the best in them... but this one time one of my colleagues gave me a code to review that, something about trees, can't remember, and the function was hammering the databases with 3 nested cycles, that's when I could no longer just watch. I was kinda mean on him that day, but as a result he did fix the problem and was really happy and I sensed a bit proud of himself as well.
Long story short, I believe he's not a software dev anymore. Kinda shame, I liked the guy, but he seemed enthusiastic of his new job and that is all that really matters in the end1 -
Ok I completely lost it... Been in a prod issue all week and basically just said the root cause is bc this team is blind....
Use the forest and trees analogy first but they still didn't seem to see it so I sent them this.
And then the chat went silent....

This is a proposal for an entirely free and open source rant like site/app.
devrant today has a couple of problems that I hate:
* Posts in the wrong categories (usually by new users)
* Low effort posts in the "recent" feed
* Good posts in the "algo" feed that are too old
* Longtime bugs
* No official code format in comments, ffs.
* Unimplemented features (like inability to search posts in android, or inability to mute posts in web desktop)
* Lack of admin involvement with the community
but it also has some aspects that I like a lot:
* Admins aren't trigger happy to suspend/ban you
* The avatars are awesome and help to associate users to faces
* The ++ system is good enough
* The community isn't too big so you know pretty much everyone
* There's a lot of variety in the roles and techonologies used by users
* Experienced ranters are usually smart
* Super simple UI
* The comments have only one level (as opposed to reddit comment trees)
This project should try to reimplement the good things while fixing the bad things.
I wrote two posts about a possible manifesto, and an implementation proposal and plan.
https://rantcourse.ddns.net/t/...
https://rantcourse.ddns.net/t/...
I think the ideas outlined there are very aligned to concerns of privacy and freedom users here vouch for.
This project is not meant to **purposefully** replace/kill/make users abandon devrant. People can continue using devrant as much as they want.
I'm hosting a discourse site on a 5$ linode machine to discuss these things. I don't know if it's better than just github.
If you feel that you would like to just use github issues, let me know. I'll create a github org tomorrow, and probably setup gitter for more dynamic discussion.21 -
There's so much hype and bullshit around Machine Learning (ML). And if I have to read one more crappy prediction of who survived on the Titantic, I'll go postal.
So, what real-world problems are you using it to address...and how successful has it been? What decisions have you supported using ML? What models did you use (e.g. logistic regression, decision trees, ANN)?
Anyone got any boringly useful examples of ML in production?
And don't say you're using it to predict survival rates for the design of new cruise ships...although, to be fair, that might be quite interesting...6 -
Ok, so I basically spent my weekend trying to work out why the fuck my python docker container would not connect to my mariadb docker container. Tried fucking everything, bridged network, host network, links (even though theyre deprecated), you name it. It would NOT WORK!
In my despair I finally turned to StackOverflow. There I was told 5min after posting the question that the reason was probably that mysql is a quite heavy service, which takes a bit to start up.
I thought to myself "Oh, get the fuck outta here, that can't be it, shit's way too easy to work!"
I tried it nevertheless by adding a 10sec delay before querying the database AND THE MOTHERFUCKING PIECE OF SHIT ACTUALLY WORKS!! So, I essentially just lost a weekend because I was too impatient... I think I'm gonna punch some trees now.4 -
So, german long distance trees are called ICE/IC (Intercity/-Express).
The wifi there, if any, is called WIFIonICE.

A company took their technical test on this really weird website. There was a Windows Narrator guy's voice giving instructions while a timer was running. I had to flash my ID to the webcam and then fit my head on an outline on the screen. It was for a web dev position. I had to speak into the microphone to answer the Narrator's questions and then send the video to them. The questions were weird and hypothetical, mostly. I just thought that their process was dumb and unnecessary.

I don't like aptitude and algebraic tests. One company, I remember, had their test on Google Forms. For some multiple choice questions, they put check boxes instead of radio buttons. So, I could just blaze through it selecting all options. Some of the questions had their first option as "All of the above" 🤔. Fortunately, I didn't pass the test.

The company I'm interning with, starting from next month, had a good interview process. They asked me questions on JavaScript, CSS, and a few on algorithms and data structures. I was also given a task where I had to make a css animation of trees. I'm glad they didn't have an algebra entry test.

Everyone and their dog is making a game, so why can't I?
1. open world (check)
2. taking inspiration from metro and fallout (check)
3. on a map roughly the size of the u.s. (check)
So I thought what I'd do is pretend to be one of those deaf mutes. While also pretending to be a programmer. Sometimes you make believe
so hard that it comes true apparently.
For the main map I thought I'd automate laying down the base map before hand tweaking it. It's been a bit of a slog. Roughly 1 pixel per mile. (okay, 1973 by 1067). The u.s. is 3.1 million miles, this would work out to 2.1 million miles instead. Eh.
Wrote the script to filter out all the ocean pixels, based on the elevation map, and output the difference. Still had to edit around the shoreline but it sped things up a lot. Just attached the elevation map, because the actual one is an ugly cluster of death magenta to represent the ocean.
Consequence of filtering is, the shoreline is messy and not entirely representative of the u.s.
The preprocessing step also added a lot of in-land 'lakes' that don't exist in some areas, like death valley. Already expected that.
But the plus side is I now have map layers for both elevation and ecology biomes. Aligning them close enough so that the heightmap wasn't displaced, and didn't cut off the shoreline in the ecology layer (at export), was a royal pain, and as super finicky. But thankfully thats done.
Next step is to go through the ecology map, copy each key color, and write down the biome id, courtesy of the 2017 ecoregions project.
From there, I write down the primary landscape features (water, plants, trees, terrain roughness, etc), anything easy to convey.
Main thing I'm interested in is tree types, because those, as tiles, convey a lot more information about the hex terrain than anything else.
Once the biomes are marked, and the tree types are written, the next step is to assign a tile to each tree type, and each density level of mountains (flat, hills, mountains, snowcapped peaks, etc).
The reference ids, colors, and numbers on the map will simplify the process.
After that, I'll write an exporter with python, and dump to csv or another format.
Next steps are laying out the instances in the level editor, that'll act as the tiles in question.
Theres a few naive approaches:
Spawn all the relevant instances at startup, and load the corresponding tiles.
Or setup chunks of instances, enough to cover the camera, and a buffer surrounding the camera. As the camera moves, reconfigure the instances to match the streamed in tile data.
Instances here make sense, because if theres any simulation going on (and I'd like there to be), they can detect in event code, when they are in the invisible buffer around the camera but not yet visible, and be activated by the camera, or deactive themselves after leaving the camera and buffer's area.
The alternative is to let a global controller stream the data in, as a series of tile IDs, corresponding to the various tile sprites, and code global interaction like tile picking into a single event, which seems unwieldy and not at all manageable. I can see it turning into a giant switch case already.
So instances it is.
Actually, if I do 16^2 pixel chunks, it only works out to 124x68 chunks in all. A few thousand, mostly inactive chunks is pretty trivial, and simplifies spawning and serializing/deserializing.
All of this doesn't account for
* putting lakes back in that aren't present
* lots of islands and parts of shores that would typically have bays and parts that jut out, need reworked.
* great lakes need refinement and corrections
* elevation key map too blocky. Need a higher resolution one while reducing color count
This can be solved by introducing some noise into the elevations, varying say, within one standard div.
* mountains will still require refinement to individual state geography. Thats for later on
* shoreline is too smooth, and needs to be less straight-line and less blocky. less corners.
* rivers need added, not just large ones but smaller ones too
* available tree assets need to be matched, as best and fully as possible, to types of trees represented in biome data, so that even if I don't have an exact match, I can still place *something* thats native or looks close enough to what you would expect in a given biome.
Ponderosa pines vs white pines for example.
This also doesn't account for 1. major and minor roads, 2. artificial and natural attractions, 3. other major features people in any given state are familiar with. 4. named places, 5. infrastructure, 6. cities and buildings and towns.
Also I'm pretty sure I cut off part of florida.
Woops, sorry everglades.
Guess I'll just make it a death-zone from nuclear fallout.
Take that gators!

Not Speaking The Same Programming Language
(It is the mid 80s, and I have a coworker come to me with two full pages of computer programming source code.)
Coworker: “Hey, can you help me with this? This function is not working right.”
Me: “Sure. What’s it do?”
Coworker: “Well, on the first line I copy…” *drones on for a few seconds about stuff I can clearly read*
Me: “Wait! Let me interrupt for a moment. I can read the code. In 20 words or less, what does this do?“
Coworker: *long pause that tells me he’s having trouble seeing the forest for the trees* “It, um, converts a date that’s a string to three integers: month, day, and year.”
Me: “Ah! Excellent. And by the time you get the string, has it been sanitized? You know, guaranteed to be pairs of digits with a slash in-between, not blanks or words or other garbage?”
Coworker: “Oh, yeah, all the user input is cleaned up.”
Me: “Okay, good.”
(I scribble “sscanf(text, “%02d/%02d/%02d”, &month, &day, &year);” in a blank spot on the page.)
Me: “Throw out everything and replace it with that.”
Coworker: “You’re kidding.”
Me: “Not at all. Use that. It’ll work. Trust me.”
Coworker: *not sure* “Well, okay.”
(Half an hour later he’s back and looking a bit sheepish.)
Coworker: “That worked. Thanks.”
Me: “No problem.”
(It’s been 30 years. Unfortunately, the new generation of programmers is in the same spot.)

(Dev)Life in the past 12 hours
Oh boy have the last 12 hours been a roller coaster ride for me. Noob me decided to "compile" AoSP for my device to get a taste of how custom ROMs are built from source. Overall it was fun but the errors were a very good excercise for googling, SO. Couple stuff I learnt ( possibly useful for anyone who comes here )
* The shebang line ( #!/usr/bin/env python ) on my system translated to Python 3.7 environment instead of the expected Python 2.7. Best solution I think to avoid confusion is to create a python 2.7 environment and source it.
* Get your trees right. A jar file called WfdCommon.jar ( apparently known as wifi-display common ) was the cause of several hours of hunting the fault. My vendor tree somehow didn't have this file so dex2oat was borking out like mad. I'm still amazed how I figured this one out almost by myself. ( Basically I had to check every file included in the boot class path, and find the odd one )
* I wasted a lot of time in finding the right files to change version numbers and all. Maybe I didn't search XDA properly for a guide ?
Overall it was a fun experience. Also if anyone's experienced in this area could you share resources to learn more about custom ROM development? Specifically on the tweaking part where you mix features from different ROMs to make a great ROM ( like AoSP extended or Pixel Experience ). All I could find were on the zips and not on sources.

I hate it when book publishers of tech books don't have their own DRM-free formats. I then have to go on Amazon and see that the Kindle version is only 10% cheaper than paper.

kinda long but please read (skip to the bullets if you're lazy):
hey dR. I stumpled across a search engine that aims to help the environment. it's called "Ecosia" and it will plant a tree for every ~45 searches you make. just think, one stubborn bug could make you the reason for a new forest! I'm not sure if it's legitimate or not, but apparently it uses 80% of its profits to plant trees, and makes that profit from ads. is it safe to use? I'm not sure.
here is what you should know (some are based on claims by ecosia and aren't proved, but probably true):
- they plant a tree for about every 45 searches you make
- they are able to plant trees by using money from ads
- they "respect privacy"
- they're "fully transparent"
- they're a "social buisness"
- [I hope this isn't a turnoff] the search results are powered by bing
- since 1.9, vivaldi has included ecosia as one of the preset search engines (I'm not sure if it's the default)
- it has opera, firefox, and chrome extensions

If you're currently in college and wish to get placed in a major tech giant like Amazon or Facebook:
Don't learn React.js, instead learn Linked lists.
Don't learn Flutter, instead learn Binary search trees.
Don't learn how to perform secure Authorization with JWTs, instead learn how to recursively reverse a singly linked list.
Don't learn how to build scalable and fault tolerant web servers, instead learn how to optimally inverse a binary search tree.
These big tech companies don't really care what real world development technologies you've mastered. Your competence in competitive programming and data structures is all that matters.

Continuation of https://devrant.com/rants/4725253/...
So I didn't get the time to post an update this morning, so an afternoon post will have to do. Today's walk was just a little past 12km, giving us all some hope to get it done in a reasonable time. The first six or so kilometers were quite harsh with winds reaching speeds of at least 15 m/s, probably closer to 20. With the rain smattering like tiny bullets our morale was pretty low. What kept us going was the knowledge that just a few kilometers ahead lay a valley a few hundred meters below our current altitude, promising warmer air, and most importantly, less wind.
As we approached the valley we could see trees appearing over the horizon, a good sign as the Swedish Fjäll generally isn't very inviting to trees, and from this point on our walk became more and more pleasant. During lunch everyone could feel the feeling of achievement lingering between us, and another three kilometers later we arrived at our cabins.
So here I am, sitting in a couch in a cozy cabin. Most of us just left the sauna, and in an hour or so we'll have a great meal and probably some celebration. Tomorrow I think we'll just chill out, perhaps pick some mushrooms, and then head to the train to wake up the next day in Malmö, ready for another week of work. Who knows, perhaps I'll even have time to squeeze in another update.
Cheers, time for a nap.

Do you think the keywords used by git (or other version control systems) are intuitive?
I'm talking to a very junior dev about git and I find myself having to explain around the fact that I don't feel the keywords are great. They are asking good questions like
* Why do you say "push the commit" but then say "make a pull request" - when I want to push why isn't it called a "push request"
* "Why are the metaphors sometimes related to trees (branches), sometimes roads (forks) but you still call it "master" instead of tree trunk or main road?
* Why do you call it "commit", what kind of commitment am I making?16 -
How many of you use the right data structures for the right situations?
As seasoned programmer and mentor Simon Allardice said: "I've met all sorts of programmers, but where the self-taught programmers fell short was knowing when to use the right data structure for the right situation. There are Arrays, ArrayLists, Sets, HashSets, singly linked Lists, doubly linked Lists, Stacks, Queues, Red-Black trees, Binary trees,.. and what the novice programmer does wrong is only use ArrayList for everything".
Most uni students don't have this problem though, for Data Structures is freshman year material. It's dry, complicated and a difficult to pass course, but it's crucial as a toolset for the programmer.
What's important is knowing what data structures are good in what situations and knowing their strengths and weaknesses. If you use an ArrayList to traverse and work with millions of records, it will be ten-fold as inefficient as using a Set. And so on, and so on.32 -

I know I’ll get mixed views for this one...
So I’ll state my claim. I agree with the philosophy of uncle bob, I also feel like he is the high level language - older version of myself personality wise.. (when I learned about uncle bob I was like this guy is just like me but not low level haha).
Anyway.. I don’t agree with everything because I think he thinks or atleast I get the vibe he thinks everything can be solved by OOP, and high level languages. This is probably where Bob and I disagree. Personally I don’t touch ruby, python and java and “those” with a 10 foot pole.
Does he make valid arguments, yes, is agile the solve all solution no.. but agile ideas do come natural and respond faster the feedback loop of product development is much smaller and the managers and clients and customers can “see things” sooner than purly waterfall.. I mean agile is the natural approach of disciplined engineers....waterfall is and was developed because the market was flooded with undisciplined engineers and continues to flood, agile is great for them but only if they are skilled in what they are doing and see the bigger picture of the forest thru the trees.. which is the entire point of waterfall, to see the forest.. the end goal... now I’m not saying agile you only see a branch of a single tree of the forest.. but too often young engineers, and beginners jump on agile because it’s “trendy” or “everyone’s doing it” or whatever the fuck reason. The point is they do it but only focus on the immediate use case, needs and deliverables due next week.
What’s wrong with that?? Well an undisciplined engineer doing agile (no I’m not talking damn scrum shit and all that marketing bullshit).. pure true agile.
They will write code for the need due next week, but they won’t realize that hmm I will have the need 3 months from now for some feature that needs to connect to this, so I better design this code with that future feature in mind...
The disciplined engineer would do that. That is why waterfall exists so ideally the big picture is painted before hand.
The undisciplined engineer will then be frustrated in the future when he has to act like the cool aid man thru the hard pre mature architectural boundaries he created and now needs links or connections that are now needed.
Does moving to agile fix that hell no.. because the undisciplined engineer is still undisciplined.
One could argue the project manager or scrum secretary... (yes scrum secretary I said that right).. is suppose to organize and create and order the features with the future in mind etc...
Bullshit ..soo basically your saying the scrum kid is suppose to be the disciplined engineer to have foresight into realizing future features and making requirements and task now that cover those things? No!
1 scrum bitch focuses too much on pleasing “stake holders” especially taken literally in start ups where the non technical idiots are too involved with the engineering team and the scrum bastard tries to ass kiss and get everything organized and tasks working so the non technical person can see pretty things work.
Scrum master is a gate keeper and is not needed and actually hinders the whole process of making a undisciplined engineer into a disciplined engineer, makes the undisciplined engineer into a “forever” code grunt... filling weekly orders of story points unable to see the forest until it’s over because the forest isn’t show to the grunt only the scrum keeper knows the big picture..... this is bad this is why waterfall is needed.
Waterfall has its own problems, But that’s another story for another day..
ANYWAY... soooo where were we ....
Ahh yess....
Clean code..
Is it a good book, yes.. does uncle bobs personality show thru the book .. yes lol.
If you know uncle bob you will understand what I just did with this post lol. I had to tangent ( at least mine was related to the topic) ...
I agree with the principles of the book, I don’t agree with the extreme view point. It’s like religion there’s the modest folks and then there are the extremists. Well he’s the preacher of the cult and he’s on the extreme side.. but that doesn’t mean he’s wrong.. many things he nails... he just hits the nail thru the wall just a bit.
OOP languages are not the solution... high level languages do not solve everything.. pininciples and concepts can be used across the board and prove valuable.. just don’t hold everything up like the 10 commandments of which you cannot deviate from.. that’s the difference here I think..
Good book, just don’t take it as the Bible as a beginner, actually infact DONT read this book as a beginner. Wait a bit learn then reflect by reading this.

Hi everyone. Thanks in advance. Although this might sound stupid, keep in mind that someone requested the following:
Someone on discord asked me to make an aim assist program for a game. I thought it might be a fun way to introduce myself to memory writing and binary trees. I accepted the request and started researching. I'm using C++ and I have some options if I need to switch programming languages. Honestly I don't know where to start, but I thought finding a color on the screen using ML or something then moving the mouse position might work. This is also one of my close friends so he wouldn't be too sad/mad if I failed the request.13 -
Here's my idea. In light of all the efforts to teach kids how to do programming, why not start with an introduction to discrete mathematics instead? From a lot of the programs I've seen, the kids are taught different structures such as if else, while, and for loops, but they don't attempt to start teaching them about recursive methods or even other structures such as linked lists, queues, dequeues, binary trees, heaps, different sorts, and other things. Am I just not looking deep enough into those programs? Or are the creators of these programs not wishing to cover those things because they feel like children wouldn't be able to comprehend such things?4

I decided I am going to get full into Minecraft modding. It will be an opportunity to learn Java and Kotlin. I want to explore some game ideas in a well defined sandbox.
Some things I want to explore.
1. AI that helps you build and survive. This fascinates me and seems like it could be a good challenge. I like the idea of learning how to separate structures into chunks. I think I will learn a bit about tree data structures here. Maybe learn something about BSP trees (if applicable).
2. The idea of an RPG quest system tacked onto a sandbox. I want to spawn structures and create non-repetitive story lines. Minecraft can be really desolate if you are not playing on a server. Worlds tend to be empty and devoid of story.
3. Maybe try a hand at terrain gen. This could be fun to explore entropy math. It is fun to draw things with math.
I am sure I will come up with other fun things to explore here.9 -

My university had a Programming Fundamentals course in the first semester and we got assigned this grumpy lady who demanded respect and would always claim she was the best at programming among her colleagues, had an obnoxiously snobbish tone and had a habit of forcing unneeded nonsensical sarcasm everytime one of us stepped up to ask her a question.
She taught C++ and I'm not saying she didn't know her stuff or anything; I respected her regardless (because she was my teacher), but she would mix up C classes in and insist that that was the right way to do it and had no consistent programming style.
Once she got so fed up with our class that just to prove her point that we're all dumb and worthless (she hated us a lot, yeah) that she started explaining binary trees and recursion out of the blue and gave us assignments for them... even though they weren't going to be covered that week. It soon became a shitfest, to be honest.
But on the plus side, because I didn't wanna listen to her lectures I pulled two all-nighters and covered the semester's worth of C++ and started napping in a corner in her class. She never had personal beef with me so I was thankful for that but her being the way she was helped me learn C++ with more motivation and vigor than I normally would have and also let me earn some change because my classmates couldn't understand her classes and wanted me to explain whatever she covered. -

... worst drunk coding experience?
none. or to be more precise, all of the three of them I had. I can't code drunk, i hate doing it, i hatw even thinking about doing it when drunk.
so after those initial three attempts i don't try to do it again, ever.
BUT, best coding experience while high?
ALL OF THEM.
some of the best pieces of code I wrote i did when I was high. my mind goes into overdrive at those times, and my thinking is not lines/threads of thought, but TREES of thought, branching and branching, all nodes of each layer of the tree coming to me AT ONCE, one packet == whole layer across all of the branches.
and the best was when one day, in about 14 hour marathon of coding while high, i wrote from scratch a whole vertical slice of my AI system that i've been toying around in my head for several years prior, and I had all of the high-level concepts ALMOST down, but could never specify them into concrete implementations.
and I do mean MY ai system, my own design, from the ground up, mixing principles of neural networks and neuropsychology/human brain that I still haven't seen even mentioned anywhere.
autonomous game ai which percieves and explores its environment and tools within it via code reflection, remembers and learns, uses tools, makes decisions for itself for its own well-being.
in the end, i had a testbed with person, zombie and shotgun.
all they had pre-defined in their brains were concepts of hunger and health. nothing more.
upon launching it, zombie realized it wants to feed, approached oblivious person, and started eating it.
at which point, purely out of how the system worked, person realized: "this hurts, the hurt is caused by zombie, therefore i hate zombie, therefore i want to hurt it", then looked around, saw the shotgun, inspected its class by reflection, realized "this can hurt stuff", picked the shotgun up, and shot the zombie.
remembered all of that, and upon seeing another zombie, shot it immediately.
it was a complete system, all it needed to become full-fledged thing was adding more concepts and usable objects, and it would automatically be able to create complex multi-stage, multi-element plans to achieve its goals/needs/wants and execute them. and the system was designed in such a way that by just adding a dictionary of natural language words for the concept objects on top of it, it should have been able to generate (crude but functional) english sentences to "talk" about its memories, explain what happened when, how it reacted, what it did and why, just by exploring the memory graph the same way as when it was doing its decision process... and by reversing the function, it should have been able to recieve (crude) english sentences that would make it learn what happened somewhere else in the gameworld to someone else, how to use stuff and tell it what to do, as in, actually transfer actual actionable usable knowledge to it...
it felt amazing to code for 14 hours straight, with no testruns during that, run it for the first time after those 14 hours, and see that happen.
and it did, i swear! while i was coding, i was routinely just realizing typos and mistakes i did 5-20 minutes ago, 4 files/classes ago! the kind you (and i) usually notice only when you try to run the thing and it bugs out.
it was a transcendental experience.
and then, two days later, i don't remember anymore what happened, but i lost all of that code.
and since then, i never mustered enough strength and resolve to try and write the whole thing again.
... that was like 4 years ago.
i hope that miracle will happen again one day...3 -

Random thoughts on more out of the box tools/environments.
Subject: Pharo
Some time ago I had shown one of my coworkers about Pharo and he quickly got the main idea behind it but mentioned how he didn't like the idea of leaving behind his text editor to deal with source code.
Some time last week I showed the dude some cool 3d animations you can do with Pharo while simultaneously manipulating the code to change them in real time. Now that caught his attention particularly and he decided he wanted to know more about the language but in particular the benefits of fucking around with an image based environment rather than a file based.
Both of us reached the conclusion that image based makes file based dev enviroments seem quaint in comparison, but estimated that it was nothing more than a sentiment rather than a fact.
We then considered what could be the advantage/disadvantages of such environments but I couldn't come up with anything other than the system not having something like Vim or VS Code or whatever which people love, but that it makes up for it with some of the craziest IDE tools I had ever seen. Plugins in this case act like source code repos that you can download and activate into your workflow in what feels something similar to VS Code being extended via plugins written in JS, and since the GUI is maleable as it is(because everything is basically just subsets of morp h windows) then extending functionality becomes so intuitive that its funny
Whereas with Emacs(for example) you have to really grind your gears with Elisp or Vimscript in Vim etc etc, with Pharo your plugin system is basicall you just adding classes that will convert your OS looking IDE into something else.
Because of how light the vm machine is, portability is a non issue, and passing pharo programs arround is not like installing Java in which you need the JVM.
Source code versioning, very important, already integrated into every live environment and can be extended to do pushes through simple key bindings with no hassle.
I dunno, I just feel that the tool is too good to be true. I keep trying to push limits into it but thus far I have found: data visualization and image modeling to work fine, web development with Teapot to be a cakewalk and work fine, therr are even packages for Arduino development.
I think its biggest con would be the image based system, but would really need to look into how this is bad by any reason other than "aww man I want vim!" since apparently some psychos already made Emacs and VS code packages for interfacing with Pharo source trees.
Embedded is certainly out of the question for any real project since its garbage collected and not the most performant cookie in the jar.
For Data science I can see some future, seems just as intuitive and interesting as a Jupyter Notebook actually, but the process can't and will not be the same since I still don't know of a way to save playground snippets unless you literally create classes for it, in which case every model you build gets saved inside of an object, sounds possible but, strange since it is not a the most common workflow in jupyter.
Some of the environment is sometimes glitchy, but it does have continuos development and have not found many hassles.
There is a biased factor from my side: I seem to be wired to understand the syntax and simple object model better than in other languages. To me this feels natural as if I was just writing ideas rather than code, mostly because I feel that there really ain't much in terms of syntax, the language gets out of my way and the IDE feels like the most intuitive environment in the world to me. I can see why some people would find it REALLY weird of counterintuitive tho.
Guess I really am a simple dude. -
So I see posts about an interview question/challenge of inverting a binary tree. I don't use trees very often (mainly file related or parsing server nodes), but I thought I would learn how to do this.
I saw a page that started talking about different ways to invert enough to understand that one type of inversion is swapping left and right nodes. So I stopped before they showed how.
Then I created a test program that has a tree structure and also can display a tree before and after modification. This was kind of fun.
So then I wrote the inversion function. It was less than 10 lines of code. Wtf? I thought it would be harder than this.
Then I started wondering where trees were used. So today I have been learning how they are used and why I might need one to solve a problem. One use I intuited was parsing regex or a language. Apparently it is useful there.
What I am learning is that a lot of these interview questions are really test to see if you can comprehend instructions when stressed. Or you will ask questions to clarify the task. It doesn't necessarily test your ability to solve hard problems.
One thing that perplexes me. If inverting a tree is swapping nodes left<->right, then why not leave data in place and just swap roles in the functions. Maybe I completely misunderstood what inversion means or why it would be done. I guess if this is not inverting I have the structure to try other methods now.2 -

I think professors should relate computational processes to mathematical ones more often. This helped me out at the beginning a lot when learning CS through the internet during high school.
I remember that a lot of the computational logic made sense to me because of math.
e.g. functions, comparators, variables, for, and, xor, sets, trees, sorting, searching etc.
A lot of these topics are hard to teach for beginning computer scientists. But I think if professors made the relationship with math from the beginning it would be easier for the students
I dont know if teachers already do this but the first time I had a professor relate math to code was while taking data structures in my second year of college1 -
Anyone tried converting speech waveforms to some type of image and then using those as training data for a stable diffusion model?
Hypothetically it should generate "ultrarealistic" waveforms for phonemes, for any given style of voice. The training labels are naturally the words or phonemes themselves, in text format (well, embedding vectors fwiw)
After that it's a matter of testing text-to-image, which should generate the relevant phonemes as images of waveforms (or your given visual representation, however you choose to pack it)
I would have tried this myself but I only have 3gb vram.
Even rudimentary voice generation that produces recognizable words from text input, would be interesting to see implemented and maybe a first for SD.
In other news:
Implementing SQL for an identity explorer. Basically the system generates sets of values for given known identities, and stores the formulas as strings, along with the values.
For any given value test set we can then cross reference to look up equivalent identities. And then we can test if these same identities hold for other test sets of actual variable values. If not, the identity string cam be removed, or gophered elsewhere in the database for further exploration and experimentation.
I'm hoping by doing this, I can somewhat automate the process of finding identities, instead of relying on logs and using the OS built-in text search for test value (which I can then look up in the files that show up, and cross reference the logged equations that produced those values), which I use to find new identities.
I was even considering processing the logs of equations and identities as some form of training data perhaps for a ML system that generates plausible new identities but that's a little outside my reach I think.
Finally, now that I know the new modular function converts semiprimes into numbers with larger factor trees, I'm thinking of writing a visual browser that maps the connections from factor tree to factor tree, making them expandable and collapsible, andallowong adjusting the formula and regenerating trees on the fly.7 -
So I'm looking at getting a drone to do some videography for commercial purposes. I've been researching all the FAA regulations, dos and don'ts, tips for flying, videography, etc. My finger is hovering over the "buy now" button on BestBuy.com.
But, there's an exam you have to take to certify to fly for commercial purposes that, I thought, was supposed to test you on the Part 107 regulations. I pull up a list of sample test questions from the FAA's own website and it has questions on it that, for all intents and purposes, apply only to MANned aircraft, not UNmanned aircraft. Crap like "What airport is located approximately 47 (degrees) 40 (minutes) N latitude and 101 (degrees) 26 (minutes) W longitude?"
And I'm sitting here like, "WTF! I don't live anywhere near there! I just want to take pictures of some friggin trees and houses in my metro area!"

In a sprint planning meeting. Getting frustrated. I guess it's my fault. I guess I assumed that attending the same schedule meeting each week meant that we all knew when everything was due. My bad.
Seriously, I fucking hate systems people sometimes. We have 4 major tasks coming down the pipe, but they are scheduled in such a way in which they are staggered. But they want to punt the 1 of the 4 that is fucking done because it is going to cause a lot of testing, but the other three aren't coming til end of next month AT LEAST. So they want to stick their thumbs up their ass holes and wait to test the other three before testing the one that, again, IS FUCKING DONE!!! Are they worried that a super massive black hole will spontaneously form in earth's orbit and cause time to run backwards and somehow cause December to happen in October!?!?
No wonder systems is so fucking far behind. They can't see the forest for the trees. They're so big picture that months and years are at the same level of granularity. Fucking hell how is scrum better than our current agile process again? Besides the fact that it makes me attend more useless meetings and get more angry.
They are punishing the left hand for the actions of the right. Systems wasn't doing their job so now software has to slow down and miss schedule.2 -

Can JS events bubble in trees of objects other than DOM nodes? If so, what properties do I need?
I tried to read this: https://dom.spec.whatwg.org//... but it's stupid long, references a bunch of other functions and I got lost in between the variables.
I'm kinda confused because it often uses type checks (i.e. if target is a Node or a Window object), which goes against the very point of duck typing.
I could technically make my nodes into DOM nodes, but I'd rather have them inherit from Worker.1 -
My experience was very recent. I was working on my game engine, Pillar3D, and realized that the setup allowed it to be automatically multithreaded with little to no concern about deadlock or race conditions. All based on the assumption that individual levels don't talk to each other, and that moving entities between levels could be done between frames. I can even track about how much work each thread has to do and use that to distribute levels among the threads. Now I can do things like force UI trees to exist in their own level and get fantastic multithreading.

I had a problem visualizing giant job/schedule dependencies trees a few years ago and basically wrote a program to convert the dependencies so it could be read in by a JS graph program that actually did the work. The output was a Gantt chart but really messed up, overlapping arrows, not very readable.
Today someone asked me for my app and but in a better format/visualization.
I so I was thinking how do I do this... Figure out which nodes are leaves, how to combine visually.
Programmatically you just link all the Nodes together. So I was thinking like how u need to use BFS and Mark when each more is traverse and on its first traversal, add it to a Map<Depth,List<Node>> then print each level, etc.
But not so straight forward.... But finally realized that I'm not trying to draw a Tree (or a tree where the rootams are actually in the middle and the top n bottom are leaves)... But actually a Graph.... A DAG....
SO FINALLY I googled and found GraphViz...
https://graphviz.gitlab.io/gallery/
And in the gallery I opened some pictures and printed at the bottom was like 1996...
And I'm now wondering "how the fuck did they do this?" Calculate where all the vertices should be placed so they can be linked with lines and and not look like a big mess...I guess like a yarnball

I can't post a collab from the web client and I don't have a decent phone atm, anyways, this is an idea, tell me if you have any improvements or if you know of an implementation or would be interested in creating one.
A social network comment system that connects people across fields of interest and aids keeping relevant posts alive for a long time.
The basic principle is this: Every post may identify itself as a child to any number of other posts, or sections in other posts, which then act much like a bidirectional hyperlink between parent and child.
This leads to two unusual results:
1. that comments aren’t only added to posts, but specific paragraphs, sentences or even words.
2. that any comment may receive comments in much the same way the original post did, making comments identical to posts. (they could have their own pages and all).
This is in many ways like Reddit's infinite comment chains. The main difference is that here comments aren’t organized in trees but graphs, which makes it possible to connect related conversations from entirely different groups and times, resulting in a much more open yet concise discourse style with an increased persistence of topics. -

Heres a fairly useless but interesting tidbit:
if i = n
then
r = (abs(((((p)-(9**i)-9)+1))-((((9**i)-(p)-9)-2)))-p+1+1)
then r%a will (almost*) always return 0. when n = floor(a/2) for the lowest non-trivial factor of a two factor product.
Thats not really the interesting bit though. The interesting bit is the result of r will always be some product with a *larger* factor tree that includes the factor A of p, but not p's other larger factor, B.
So, useless from what I can see. But its an interesting function on its own, simply because of what it does.
I wrote a script to test it. For all two-factor products of the first 1000 primes, (with no repeating combinations, so if we calculated say, 23*31, we skip 31*23), only 3262 products failed this little formula, out of half a million.
All others reliably returned 0 for the following..
~~~
i = floor(a/2)
r = (abs(((((p)-(9**i)-9)+1))-((((9**i)-(p)-9)-2)))-p+1+1)
r%a
~~~
The distribution of failures was *very* early on in the set of factors, and once fixed at the value of 3262, stopped increasing for the rest of the run.
I didn't calculate if some primes were more likely to cause a product to fail or not. Nor the factor trees, nor if the factor trees had any factors in common between products, or anything of that nature.
All in all I count this as a worthwhile experiment.
If you want to run the code yourself, I posted it to pastebin here:

I just woke up from a fun adrenaline packed film dream.
It started like an movie, leaning a bit into the funny side, but also a bit serious.
We were 3 guys going top speed on the highway, dodging traffic, trying to prevent a bomb from detonating on the other side of the city.
We were all famous actors, but the only one I remember was Jackie Chan. I remember thinking why would they cast Jackie Chan and give him so few lines.
I wished I remember more about this part. The only thing I remember is that when we get to the end of the island, we’re in the wrong place: we’re at a huge OBGYN center.
My sidekicks are bothering the desk women, eating all of the “waiting candy”. I feel bad and offer to pay those, which they pretend to not care about but then end up charging me down to the penny. Cunts.
The sidekicks leave and (without explanation because dreams) disappear of the story.
Defeated, I go outside and start walking.
And I don’t remember exactly what the fuck happened in between, but somehow I’m now in the house of a cartel druglord and he’s pissed and I need to run now.
So I do. I remembered that there was a very thick forest east to the house. So I go there.
And what follows is a very intense montage of me escaping.
At some point that forest ended, so I continue through some high weed, and then another forest, and so on. While I had to pass through parts with no vegetation, I had to avoid these as much as possible.
I saw dozens of types of trees and shrubs.
Then I started seeing families, kids, playing, relaxing on what seemed a Sunday afternoon.
The adventure was so fun, the landscape was so beautiful I felt happy and thought “this is how it feels to be alive”. And I actually felt happy in real life as well.
At some point the vegetation I encounter decreased, and I have to go through more urbanized areas, with more people.
“Uh oh” I think, “I hope no one snitches me”. But miraculously, no one does.
Throughout all the journey I had glimpses of the drug lord nearby presence.
His face on the distance, the sound of his car engine.
But now he was closer than ever. And I’m closer to this house which is the escape point (can’t really remember why).
So I reach for the handle and fade to white, and fade back again, it’s me, older, and I’m not in an escaping mood.
My wife is waiting, our car is outside (on the non drug lord side).
And guess what, we were waiting for our daughter, who comes with a smile and a child on her hands.
So apparently, my daughter married someone from the drug lord villa that almost murders me.
Reading this sounds like a bad script, but that’s what I dreamed today.1 -

I think I may have just had a bit of an epiphany...
Algorithms and Data Structures are sort of like libraries and frameworks.
JS is probably the easiest example since npm has a lot of libraries.
For most cases, underscore.each and lodash.each $.each achieve pretty much the same thing except one maybe better in certain cases.
And data structures are sort of like Angular, React, Electron, ReactNative. Each has its own purpose or style and are good for solving certain types of problems?
So day-to-day you don't really care what Sort() algo you use.. unless you really need to perfoarmance tune it for a specific case.
And data structures, depending on the type of problem you have, one is easier to work/think about the problem in although not examply... Usually have to use a few of them at once.
How is this going to help me in interviews... I'm not sure... other than reconfirming that knowing specific implementations of Sort and Trees is usually BS... most of the time just need to know you should Sort or use a Tree... -
So I'm writing my compiler and I decide to test error handling, see if I'm catching unexpected tokens and whatnot. I try duplicating a semi-colon at the end of a line, for sure it'll give me an error since that's an unexpected token, isn't it? So I run the compiler and... No errors? I start debugging for a few minutes, snoop around, everything seems ok... "Huh, that's weird" and then it dawns on me, a semi-colon only marks the end of a statement. So, technically, it's not an unexpected token if you have an empty statement (which wouldn't break any rules about statements). I decide to try out my theory. I put ;;;;;;;; at the end of a random line in my rust code, hit compile and... it compiles! So that means it is not a bug anymore! I mean, if the big guys that actually know a tad about language design, compilers and all that cool stuff allow it in their languages, why shouldn't it? So I did it, I turned a bug into a feature and now I can go to sleep in peace and stop dreaming about fucking abstract syntax trees (don't mind my kinks >:) ).
Yeah anyways thanks for reading, till next time! Bye!1 -
Rustfmt doesn't support inline function calls with a block last argument unless the last argument is an array literal or lambda. Dedicated support for arrays is obviously intended for XML-like trees where a factory takes a number of arguments and then a list of children, and the use cases for block last lambda argument don't need explanation, but what I don't get is how did no one catch on that this is a useful pattern that should perhaps be generalized? Why can't I produce the same behaviour for a function call in the last position.3
