This is going to be a long rant, coz this is the only way to vent out my frustration against our tech head.

Yesterday, while our fucking twat tech head was playing around in company aws account, he terminated the production server. By mistake, apparently. Coz he doesn't know shit about server management. But that egoist ass won't admit and fucked the production server.

And then ran away. We developers sprang into action. Updated dns to point to staging server, setup virtual hosts, env files, point to prod database, force flush dns cache. All systems were up and running in 30 mins. And since it was staging server, it had lot of untested features and codes, and we spent rest of the day fixing the bugs.

And that tech head, who ran away hiding his tail between his legs, after he fucked the server, came back after systems were up. And started cracking jokes, that "so many features got released in 1 day" . "We cut server cost by shutting down 1 server."

We were struggling and working in full throttle to make the services running again. And that fuckity fucker was cracking jokes.

And I don't even know what excuse he gave to ceo for the downtime. I am pretty sure he would have made up some crappy excuse to hide his fucking mistake. That ass never admits his mistake. I am thinking to go to ceo today and tell the real story and get that faggot head fired or at least a strict warning.

Boss wanted me to make changes in company's website which was based on wordpres s.

I knew it could be done by tweaking some JS code, but I have very less experience with wordpress

But wordpress is easy man(Internet told me).

Give me 5 minutes, you will see the changes in production.
Being lazy af I directly logged in to ftp, checked out some files, updated some code, I was good to go.

Before pushing it, I opened the website and it was GONE ٩(๑´0`๑)۶

Now there was no public_html in the root.
I was fucked. I have accidentally deleted the website that had no backup.

And the best part I was on leave from
next day.

I was looking everywhere for backups, looked into google cache to get the contents. I have to recreate the complete site now.

Just when I was asking questions on choice of my profession and simultaneously looking here and there in FTP for backups,
I found the jewel "public_html".

It happens out that I have accidentally moved the folder to some other directory.

Phewww.

Moved it back to root. Site was up and running.

Reassured myself that I deserve to be a dev.

Backed up complete site, made the changes.

Uploaded it.

And the best part, amount of wordpress I learned in those three hours was way more than I could have learnt in many weeks.

Lessons Learnt :

A) ALWAYS keep backups.
B) You SHOULD NOT make changes on prod directly
C) You become superhuman when your brain know you are going to be fucked 😂

Is your code green?

I've been thinking a lot about this for the past year. There was recently an article on this on slashdot.

I like optimising things to a reasonable degree and avoid bloat. What are some signs of code that isn't green?

* Use of technology that says its fast without real expert review and measurement. Lots of tech out their claims to be fast but actually isn't or is doing so by saturation resources while being inefficient.
* It uses caching. Many might find that counter intuitive. In technology it is surprisingly common to see people scale or cache rather than directly fixing the thing that's watt expensive which is compounded when the cache has weak coverage.
* It uses scaling. Originally scaling was a last resort. The reason is simple, it introduces excessive complexity. Today it's common to see people scale things rather than make them efficient. You end up needing ten instances when a bit of skill could bring you down to one which could scale as well but likely wont need to.
* It uses a non-trivial framework. Frameworks are rarely fast. Most will fall in the range of ten to a thousand times slower in terms of CPU usage. Memory bloat may also force the need for more instances. Frameworks written on already slow high level languages may be especially bad.
* Lacks optimisations for obvious bottlenecks.
* It runs slowly.
* It lacks even basic resource usage measurement.

Unfortunately smells are not enough on their own but are a start. Real measurement and expert review is always the only way to get an idea of if your code is reasonably green.

I find it not uncommon to see things require tens to hundreds to thousands of resources than needed if not more.

In terms of cycles that can be the difference between needing a single core and a thousand cores.

This is common in the industry but it's not because people didn't write everything in assembly. It's usually leaning toward the extreme opposite.

Optimisations are often easy and don't require writing code in binary. In fact the resulting code is often simpler. Excess complexity and inefficient code tend to go hand in hand. Sometimes a code cleaning service is all you need to enhance your green.

I once rewrote a data parsing library that had to parse a hundred MB and was a performance hotspot into C from an interpreted language. I measured it and the results were good. It had been optimised as much as possible in the interpreted version but way still 50 times faster minimum in C.

I recently stumbled upon someone's attempt to do the same and I was able to optimise the interpreted version in five minutes to be twice as fast as the C++ version.

I see opportunity to optimise everywhere in software. A billion KG CO2 could be saved easy if a few green code shops popped up. It's also often a net win. Faster software, lower costs, lower management burden... I'm thinking of starting a consultancy.

The problem is after witnessing the likes of Greta Thunberg then if that's what the next generation has in store then as far as I'm concerned the world can fucking burn and her generation along with it.

Powershell. Using classes. Can't create class libraries using regular .ps1 files (this way this **sort** of work). Using modules then. Can't easily refresh modules cache after any change to a class. Need restarting powrshell each time. Looking for more information. The issue is open since 2016 (just after the release of PS 5 that introduced classes). Once again, a Microsoft product turns out to be shiny at the beginning, but rusty when you go beyond the surface. Classes seem to be second class citizens in powershell. I feel frustrated and I would like to put pressure on microsoft but nobody seems to care. I'm stuck.

I've ranted about this before, but here we go again:

Go Plugins.

I was racking my brains trying to figure out how one could possibly implement plugins easily in Go.

I had a look at using RPC, which requires far to much boilerplate to be realistic. I looked at using Lua, but there doesn't seem to be a straight forward way of using it. I was even about to go with using WASM (yes, WASM). But then I came across Yaegi ("Yet another elegant Go interpreter", you heard right: "interpreter"), Yaegi is also very easy to use.

There are a few issues (including some I haven't solved yet), including flexibility (multiple types of plugins), module support, etc. Fortunately, Traefik just released their plugin system which is based on Yaegi (same company), and I got to learn a few tricks from them.

Here's how module loading works: The developer vendors their dependencies and pushes them to a repo. The user downloads the repo as a zip and saves it to the plugins folder. I hash the zip, unzip it to a cache, and set the the GOPATH for the interpreter to be that extracted folder. I then load the module (which is defined by a config file in the folder), and save it for later. This is the relatively easy part.

The hard part is allowing for different types of plugins. It looks easy, but Go has a strict typing system, makes things complicated. I'm in the process of solving this problem, and so far it should go like this: Check that the plugin fits an arbitrary interface, and if it does, we're good the go. I will just have to apply the returned plugin to that interface. I don't like this method for a few reasons, but hopefully with generics it will become a bit more clean.

I hate group project so much.

I yet again successfully stirred up a big drama in my project group. For project, I proposed a CDN cache system for a post only database server. Super simple. I wanted to see what ideas other people come up with. So I said I am not good at the content and the idea is dumb. Oh man, what a horrible mistake. One group member wants to build a chat app with distributed storage. We implemented get/put for a terribly designed key value store and now they want to build a freaking chat app on top of a more stupid kV store using golang standard lib. I don't think any of those fools understand the challenges that comes with the distributed storage.

I sent a video explaining part of crdt. "That's way too complicated. Why are you making everything complicated."

Those fools leave too much details for course stuff's interpretation and says

"course stuff will only grade the project according to the proposal. It's in the project description".

I asked why don't they just take baby steps and just go with their underlying terribly designed kV store.

"Messaging app is more interesting and designing kV store with generic API is just as difficult"

😂 Fucking egos

Then I successfully pissed off all group members with relatively respectful words then pissed off myself and joined another group.

Hello, I have a question for anyone familiar with multithreading!

I just started working with threading for the first time, I mostly write powershell scripts 😅, I found that certain conditions make using multithreading an absolute time saver. And of course in some tasks it's not such a big deal.

I am currently working on a project that runs multiple threads and each thread might invoke one of my functions that also threads the work.

I'm a total newbhat when it comes to this stuff, but if my main process is 4 threads, and I can spin up, up-to 4 more threads to run one of my functions, does the math equate to a possible total number of threads of 16 or is it possible to have the threading go ape-shit bananas and utterly thrash the cpu with rampant threads getting created?

I've looked online and based on some of the info that I've managed to come across on my own, the answers elude towards being safe because I'm creating pools for running the threads first and the pool is responsible for maintaining min/max threads, but I can't seem to find good info on running a pool+threads inside another thread.

Just to let you in on what the function does that requires threading in the first place, I need to basically query CloudTrail based on ARN's to find events, but I can only pass a single ARN to the find-ctevent cmdlet. So I'm essentially making 1500-ish really really small calls to AWS just to get back event data for the ARN.

Serially, this takes like almost 20 mins, on my laptop using stupid settings like 24 threads, it completes in about 95seconds. On the actual server that will be running this code, I'm going to limit it to 4 threads and try to figure out a way to cache the info locally and update the info on a cron or schedule so only the initial scrape takes forever and then the updates can be done nightly or something.

thank you in advance for your help, I'm not too sure if the question is dumb but please let me know either way!

When you're testing a website on the iPhone and in order to clear the cache you have to go through settings menu just to try a fucking tweak out.

Is there any way on the iPhone to do it quickly? < iOS11 you could tap refresh 5 times. ARGHHH
