Wife: I got a Roomba for Christmas!

Dev Husband: oh.

Dev Husband *hours later* : Did you know it has an MQTT interface accessible over IP? I already wrote a NodeJS app to track if we need to empty the bin.

Devrant meetup Nijmegen

That's actually something that happened fairly recently.. just that I didn't have the energy left at the time to write it down. That, or I got my ass too drunk to properly write anything.. not sure actually.

So on paper I'm unemployed, but I do spend some time still on pretty much voluntary work for HackingVision, along with a handful of other people.

At the time, we were just doing the usual chit-chat in the admin channel, me still sick in my bed (actually that means that I wasn't drunk but really tired for once.. amazing!) and catching up to what happened, but unable to do any useful work in this sick state. So, tablet, typing on glass, right. I didn't have any keyboard attached at the time.

One of the staff members (a wanketeer from India) apparently had an assignment in a few hours for which he needed to write a server application in Java. Now, performance issues aside, I figured.. well I've got quite a bit of experience with servers, as well as some with client-server protocols. So I got thinking.. mail servers, way too overengineered. Web servers.. well that could work, I've done some basic netcat webservers that just sent an HTTP 200 OK and the file, those worked fine.. although super basic of course. And then there's IRC, which I've actually talked to an InspIRCd server through telnet before (which by the way is pretty much the only thing that telnet is still useful for, something that was never its purpose, lol) and realized that that protocol is actually quite easy to develop around. That's why I like it so much over modern chat protocols like XMPP, MQTT and whatnot. So I recommended that he'd write a little IRC server in Java. Or even just a chatbot like I attempted to at the time, considering that that's - with a stretch of course - a sort-of server too.

His fucking response however, so goddamn fucking infuriating. "If the protocol is so easy, then please write me down how to implement it in Java."

Essentially do his fucking work for him. I don't know Java, but as a fucking HackingVision admin, YOU SHOULD FUCKING KNOW THAT HACKERS CAN'T STAND LAZY CUNTS THAT CAN'T EVEN BE ASSED TO GOOGLE SHIT!!! If I wanted to deal with cunts like that, I'd have opened the page inbox with all its Fb h4xx0ring questions, not the fucking admin chat!

And type it on a goddamn fucking piece of glass, while fucking sick?! Get your ass fucked by a bobs and vegana horny fuck from the untouchable caste, because that's where you fucking belong for expecting THAT from me, you fucking bhenchod.

But at least I didn't get my ass enraged like that to say that to him in the admin chat. Although that probably wouldn't have been a bad thing, to get his feet right back on the ground again.

Apparently, floating point math is broken.

=SUM((2.1 - 2.0) - 0.1)

In PHP and Haskell this also happens

Thought this was a good bug fix message on the app store

Wishing everyone a good morning and a good week

Get lost.

Dear Hipchat, if you are going to implement an Autocorrect Feature, LEARN THE FN TECH LANGUAGE

if i type gradle i do not mean grade
if i type coap, i do not mean soap
if i type mqtt i do not mean mitt
and for f-shake hipchat is not "hip chat", how do you even mess that one up!

Seriously what's wrong with the market right now, this is basically what some job ads said. They were even from the same company

Frontend job ad: are you a rainbow rockstar developer who just loves to code OwO(unpaid overtime) [buzzwords...]

Embedded systems job ad:
Serious job description
Required experience in c/c++
Other non bs stuff

Just needing somewhere to let some steam off

Tl;dr: perfectly fine commandline system is replaced by bad ui system because it has a ui.

For a while now we have had a development k8s cluster for the dev team. Using helm as composing framework everything worked perfectly via the console. Being able to quickly test new code to existing apps, and even deploy new (and even third party apps) on a simar-to-production system was a breeze.

Introducing Rancher

We are now required to commit every helm configuration change to a git repository and merge to master (master is used on dev and prod) before even being able to test the the configuration change, as the package is not created until after the merge is completed.

Rolling out new tags now also requires a VCS change as you have to point to the docker image version within a file.

As we now have this awesome new system, the ops didn't see a reason to give us access to kubectl. So the dev team is stuck with a ui, but this should give the dev team more flexibility and independence, and more people from the team can roll releases.

Back to reality: since the new system we have hogged more time from ops than we have done in a while, everyone needs to learn a new unintuitive tool, and the funny thing, only a few people can actually accept VCS changes as it impacts dev and prod. So the entire reason this was done, so it is reachable to more people, is out the window.

Just in case any other devranters are in China, here is this morning's updated chart if you have wechat you can follow this account, stay safe and wash your hands

I find it so unbelievably satisfying to see trend patterns in the client launches from the user's that use my mod. Basically, every week the number of people using it grow, but it keeps the same rhythm.

Sunday most people of the week, Monday least people of the week; then building up to Sunday every day a little more. BUT then there's Thursday where a few people are taking an early night or something.

I guess the satisfying part is just that, however, how random and unique everyone thinks that they are. In a crowd - everyone together - shows a lot of patterns and similarities.

Samsung has a bug in their galaxy software that essentially makes you unable to store anything that's not in the root folder on an additional sd card. After 2 years, they still have the bug. Additionally some phones will shit themselves if you try to format an sd card with it

How the fuck can they just leave significant bugs. The whole just get a new phone every other year mentality/industry style is both wasteful and seems to contribute to garbage software

Pokemon go is down so I'm coming crawling back... can I come back to devrant? please accept me (until the servers are back)

Just found out that MQTT.fx stores user credentials in plain text in a xml file.
WTF?!
I mean it's only stored locally but it's still a bit worrying.

Long time no see devRant. This rant is dedicated to an MQTT implementation we use. Mosquitto, mqtt.js - FUCK YOU.

I spent the last fucking 30+ hours trying to find why the bloody fuck the stupid server / client won't connect to the shitty mqtt broker. From changing all possible config, enabling & disabling specific code nothing abso-fucking-lutely works.

But then it will randomly decide to connect to the fucking broker, not causing any issues at all. And each fucking day when I wake up again and think to myself: oh today I can actually leave when it is still somewhat bright outside - NOPE. Because guess what? The fucking shitty abomination doesn't work anymore.

I just love these types of problems that are almost impossible to debug because the only logs you get is: "SERVER disconnected". It's impossible to get a proper reason out of this shit show, it's just turned into randomly guessing what the error could be (and especially where it could be).

And each time I got it to work, tested it and let the testing team know that they can start testing it will just stab me in the back and be like "fuck you, I'm not working any more". Luckily it's not like the deadline is next week... otherwise work is great, trust me.

My personal top 4:
good tea,
good booze,
time with gf,
time with friends,

Just clears my head, but doing any of my other hobbies can really help because it just gets me in a different headspace

!rant :) FUUUUUUUUDGE YEAAAAH!
it's so satisfying when you've been working on a huge ass thing(when maybe you should have tested individual parts) and it just fucking works as intended amazing, I love it!

It's so beautiful to see your own compiler(jk just scanner+parser atm) compile code successfully

Learning rust with a very tight deadline. Not something I'd recommend since you will be likely to spend more time trying to get your project to compile than getting on with your project.
In my case the project was a compiler(in hindsight I'd have picked ocaml or scala instead).

Ayyyyy folks
I'm looking for some beta testers. Preferably if you use a MQTT broker with some IoT connected shit.
Bonus points for IFTTT.
Leave something in the comments if you're interested and I'll get in touch if the time has come

Besides firefox and emacs there is also Linux, the library emacs uses to interact with the computer hardware

Flutter chat client using MQTT

Emacs, once you gotten familiar it's just the best and there's lots of packages to make everything easy to do from emacs. Also it's very configurable

Okay so for all of you who think that you can't do shit without stackoverflow. I'll tell you this, fuck SO. There's this ancient technique of programmers of old probably just about 20-25 years ago called RTFM. Why bother copy pasting some one else's spaghetti(that you might not fully understand) when you can write your own better code! (said in good faith). When something is behaving strange or you don't know what something requires just hit the docs or manual and read about the api because it is describes not only what it wants and needs but also what it does. So try this because it might have more information that you need than stack overflow might tell you

I have been working on IoT projects for last five years. After using MQTT in many of my projects I have realized that there is a huge learning curve for the beginners to understand and implement MQTT in their projects. The packet structure of MQTT is complex and MQTT packets are difficult to debug. Also customizing the open source MQTT brokers are also difficult for the beginners, and sometimes even for the experts.

To make IoT and Messaging simple, I am designing a new protocol which uses JSON packets for data exchange and is far less complex than MQTT. I am also developing an open source project which will contain a server (with load balancer support), a python client, a Javascript client and a python based load balancer. I hope this project will reduce the development time as the protocol is easy to understand and the open source code is fully modular & easy to customize.

This will be my very first contribution to the open source community. Wish me luck!

Devrant works surprisingly well here in China, except for saving pictures everything else works(mostly) but it's still nice to be able to use it here

Anyone else have similar experience in their country?

Fucking MQTT, go suck some dicks! Can't get that pice of shit to work, sending connect and publish works like a charm but somehow I won't get an acknowledge message which means the publish doesn't go through!
On the brigt side: another oportunity to fire up wireshark and compare my software to other tools.

Anyone expirienced wit MQTT or thingstream.io

P.s. there support also can go and choke on some dicks!

Just created my own publish-subscribe-based IoT protocol for the NodeMCU. It's like a simplified version of MQTT and pretty error-rich. (So it shouldn't be used in important cases). But the cool thing is that you can use a simple NodeMCU to host a server and don't need to set up a Mosquitto Server on a Linux Machine.

Will release on GitHub soon!
Also made an example Client in PHP!

Yo, so does anyone here have any experience about using Windows or mac printer drivers on GNU+Linux? So far my strategy has been to try to extract a ppd file from the Windows/mac drivers. It's an epilog fusion laser printer/engraver

I hate windows, I hate office, but for some reason I keep using it.

What's your favorite standard? Mine is rfc 2549 aka IPoAC

Is it just me or did the algo become like top of the week(or arbitrary time period)?

Rust is a nice language but the learning curve is quit steep so if you don't have time to pick it up I'd suggest using another language especially for assignments if they give you the choice. Otherwise you might like me and my classmates spend more time fighting the rust compiler than doing the assignment

Just lots of coffee to be honest

Running NPM install on an average size project on a free tier Cloud9 instance.

Didn't go too well kept hitting memory limit which killed the NPM process.

Upgrade it is..

Use MQTT protocol as a chat protocol and create a Flutter client

Fuck

Stupidly tested some sql on development to return results for an admin (see the whole results) and stupidly didn't test the where clause for generic users (only see a subset of data)

To find out on production the where clause was being run because it wasn't a where, it was an 'and' and 'where' was not being used before so made the whole users get the entire results.

My own fault for not testing all use cases. Horrible though.

Argos status 500.

Nice user error message.

!rant very happy to see a development at my uni towards having programming(+related courses) being more and more examined throughout the course through assignments and seminars where you have to explain what you did and why. I think this is a much more suitable solution for some courses best done with practise than having a paper based exam.

My dad showed me vb.net when I was 13 or something and just went ahead to try to make different types of games with Windows forms, it was a lot of fun even if the games were garbage(I had a gazillion buttons on one because I couldn't figure out how to make the logic reusable with the hp bar); it is what put me on the programmer/engineering path

MQTT:

If I manage to complete my current project as intended then it will be my most successful project so far

Should I use Netlify or heroku for a react app that possibly uses mqtt or does it not matter?

MQTT - all I used to know about this is its name, untill few months back a client sent us some requirements which included MQTT. I opened its specification and I was fucking shocked! I am implementing almost similar protocol in most of my applications (which needs subscription based service) for last 3 years. I have developed IoT apps, remote monitoring systems, HMI systems using the same fucking protocol! Even I had implemented the same thing on HTTP using long polling a few years back!!

Now I feel like open sourcing my protocol. But I don't know where to start. Any help please?

Hey i want to make a chat application for production workload with more than 100000 simultaneous connection and more than 1000000 daily active user which will scale 100 times in coming 1 to 2 years for Android. I have oauth based user authentication. This chat should be able to authenticate and verify authtoken generated using the oauth. What should i use? Xmpp, mqtt or something else. Can anyone who has worked on chat application help me.

Did ingenico just assume my gender?

I'm working on my own smarthome project (how rare nowdays...:) ). I'm using microsoft's git repo. I'm not make my project open source, not because I'm a douchebag, but because I'm a very bad coder. My biggest fear is not the fact, that it would be commented as wtf is this code, but receiving pull requests from pros and I wouldn't even understand their code.
This is my "training" project (python, flask, apscheduler, sqlalchemy, bootstrap2, mqtt, micropython)
I'm thinking to make it public without accepting external pulls, just for me to learn more.
I'm just wondering your thoughts on this.
Thoughts?

I am working on a pub-sub based protocol (like MQTT) with some added features. I am developing a python based server for my protocol which can be run on distributed architecture with load balancing without any tweaks. I am planning to make this server and the protocol open source.

The whole thing is getting so complex that I think about scrapping this project sometimes. I need your inspiration guys. Really, I need it. I know this protocol will be good enough to help people working on IoT, chat or any pub-sub based application if I can complete it. Cheer me up, please.

I was trying to set up my own "cloud" for iot experiments. I planned to use Intel Edison with mqtt broker (using mosca) and a node js app for providing API for mobiles and browser. And also to do other book keeping.

I spent the half day trying figure how to expose these servers to internet.

I configured ddns in noip.com and ddns settings configured to it in my router.
Port forwarded to the local server services I needed.

And then tested. Worked perfectly on any device in my router connected network. Tested on mobile network. Bam! It fucking doesn't work.

Then connected another router.
Double port forwarded. Again worked perfectly on router network. And failed on mobile.
Tested if ddns is right. Did nslookup it was fine as fuck.
Then disabled port forwarding. Did dmz. Nope. Nadda. No luck.

Then scratched my head so hard that I lost more already losing hairs.

Then remembered about router hardware firewall. Disabled it.
Tested
And there it didn't work.
My dreams shattered like a fucking deer hit by car on highway.
Didn't work.
Then I see the IP pointing to my router in nslookup. Its 172.20.xx.xx. Its a fucking private IP.

My Asshole ISP is running another private network behind firewall. Which I fucking can't port forward
Now I think how much of a noob and idiot I am. Fuck this shit. Fuck all of these shit.
I am going for SaaS option for mqtt broker.
(Or help me?)
Once again.
Asshole ISP.
Fuck your firewall.
(PS: I had test the next day. FML)

Do you have a programmers union in your country?
In my country we have a general union for all different kinds of jobs and a engineers union. Maybe if developers had a dev union there would perhaps be less bs

Any tips for doing well on the technical interview?

It's my first time doing a technical interview so any tips are welcome. It is for a (paid) field application engineering internship. They said it would mostly be regarding electronics

When you are leading in updating a product to the latest version of a framework, what allows the integration of webpack into it, and so also allows the usage of babel, what allows the usage of ES6 syntax.

And now everyone in the company started calling the "new javascript codes" a part of the framework, even though i explained multiple times how it works.

I have multiple ones, my uni has for one several amazing professors that I admire. Then there's there's the classics Thompson, kernighan, djikstra et al. T.A.D, uncle Bob and last but not least Stallman

All of them has provided insights, knowledge and a better way to view code and software

Remove a property from an array to spend an hour trying to work out why something isn't running to notice that there was a count later on the array that required a specific number of elements so the bit I was expecting to execute never executed.
Was looking for ages as to why.

Friday afternoon code brain.

Never thought I'd say this, but migrated a project to Azure and started using MQTT instead of LwM2M, and I am impressed with Azure IoT hub and how easy the process was.

Sometimes while writing software / consulting I feel like house md. Not always am I right the first time, but this is often due to me looking at the wrong thing. But at the end of the day I am able to give advice that may be seen absurd but usually is correct.

(tip: it's never lupus, what is quite right because code is code)

Any computer engineering students here on devrant? !rant btw

I believe that there's some evil dark magic in the BEAM that detects if the user or developer is on a non *nix machine and then purposefully throws all kinds of strange errors or just fucking blows itself up for no reason. Take the shit to a *nix machine and it just works like magic and is easy to work with which is part of the reason why I love it and the ecosystem.

What container/virtualisation technology do you guys prefer?

Also I've been thinking of picking up either k8s or docker, mainly docker for ease of deployment or do you think it's wortb learning both perhaps? I do know they have a bit of different use cases
