First time poster here. Please be nice :)

My biggest workaround is one that's being currently deployed to 40 truck drivers (trucking company here), preventing printers being out of usage while on the road. We also have to use HP ePrint to wirelessly print documents, but that's another story for another time I guess :)

CEO asked us to install wifi printers in our 40-ish trucks which has wifi on board. However he's always picking one of the cheapest options possible, so we got consumer grade printers (Laserjet 1002w). Those printers often disconnects without getting back on the truck wifi network EVER. I have to get physically in the truck, wire the printer via USB onto my laptop and reconfigure Wifi on it with the HP Windows tool. This means lots of printer downtime, which always happens when the drivers are three timezones away from our office

Then I thought: "What if I could sniff what HP sends via USB while I (re)configure the printer, and replay whats being sent later? Our trucks all have an Android tablet with a USB type-A connector with host capability, so I could write a small app that replays the config when plugged in by the user.

Three days of hacking around later, I have a working app. By chance, HP printers (or at least those models we have) uses HTTP POST via USB, so I could easily replay the request.

Edit: the end result is that truck drivers just plug the printer to their tablet, press "reconfigure" in a home made Android app, printer is reconnected to the truck and they're good to go. They don't have access to the network nor know enough to debug themselves anyways

Back when I was in school (about 15 years old) and I played games, I had a particularly favourite game that I would play. It was a lesser known strategy game made by a single hobbyist Dev.

I was already known in the community for making some mods for the game and chatbots.

What most people didn't know was that I had made a map hack and various other cheats that made it significantly easier to win by reverse engineering the game and modifying the x86 assembly in ollydbg.
One thing in particular I had been working on at the time was a game replay editor. I had reverse engineered the saved game (replay) format and was able to replay them, edit them and generate them.

During one particular match, a person in the community particularly annoyed me and I edited the saved game to change what his moves were and the words he spoke. It made him look a bit like an idiot but IMHO was only a slight exaggeration of the truth.
I posted the game replay on the forums and everyone was in hysterics about the crazy things he did and said in the replay.
As no one knew I had this capability they all believed the replay and even the guy in the replay couldn't believe it himself and didn't understand what happened. He just kept telling everyone it didn't happen and the 'truth is in the pudding'.

Although I originally intended to tell everyone what I did, I never did and whenever the guy entered in to a game everyone would laugh about it and say 'the truth was in the pudding'.

He was no longer annoying me and it sort of made me feel like a god at the time.
So that's my wk65.

Early morning I walk in to a build failure email.
"Oh shit! It failed and I'm on the Cc list."
.
"Please don't be me. Please don't be me. Didn't I build it already?" *compulsively launches local build*
*Ctrl-C's current build and feels angry for doubting self*
*Repeats, while trying to replay the incidents of last night in the head.*
"Fuck this. I'm certain I built the module."
.. scrolls email ..
"This is not even my change!"
.. scroll ..
"This is not even my code base!"
*feels foolish, but MAJORLY relieved*

Had a LinkedIn recruiter contact me a few months ago, I usually get one of these a week at minimum and usually more frequent the moment a start a new position. I hate that!

Anyway, story and rant:

The recruiter sent me a position that was pretty good, lots of benefits, not too far to drive, some remote days. With the usual list of responsibilities that they themselves dont know what half of them are but put them on anyway, I would automate those anyway if I wanted to work there.

All looks great, I ask if they can send me more details and the budget they company has for the position.

This was for a Senior position so I thought they would know what industry standard is.

The recruiter replies with a budget: $2000

I actually couldn't believe that they thought that was acceptable amount of money for the amount of responsibilities they wanted this new senior guy to do, no wonder the previous guy left.

I respond and told her that the amount is extremely low for what they want and I dont think they will find someone with the skills they need at that amount. I would be willing to talk for a minimum of $4000 and thats not guaranteed until I can go for a formal interview to find out exactly what the company needs.

The recruiters replay was probably the rudest anyone has ever been to me online, lol! She insists its industry standards and any Senior would be lucky to get such a great paycheck, the company has been in business for years and their developers have always been happy and paid industry standards.

I respond again and tell her that im getting $3800 at this small company where I currently am and if the "international company with clients all over the world" wants to have my skill set why is it that they cant pay premium salaries!? As well as the graphs for my Country on what the current industry standards are for salaries in my industry.

She never replied, but I kept tabs on the company she was recruiting for. They are still looking for a senior dev, its been 8 months now and no one has applied.

I am so happy more developers are standing up for themselves and not taking agencies bullshit with low salaries, crazy overtime and bad technical specs.

Note: Amounts are made up, was just to show comparison.

So there was that paranoid schizophrenic person, a blonde girl with a buzz cut, and somehow she was a friend of mine. She used a Linux distro called “!!!!!!!!____!!!!!”, and convinced me it was the best distro out there. But the way she used it was… very specific.

She called me. She told me the new distro was out, this time it was called “!!!!!!!!!!!!!!!!!”, and _this_ was the best one. It finally allowed her to observe the area around her neighbourhood right from her PC, through some app, and make pits in the ground. It was done with a touchscreen of a Nintendo DSi connected to her PC with something that looked like an IDE cable. You touch the area of the screen, and the pit will appear outside IRL. This was needed to trap swine-looking creatures in those pits, as they infested the land and were attacking people in packs, turning them into dirty, greyish, half-transparent lumps of gel.

I went to see her, and somehow I knew exactly how it's going to end, as if I decided to replay a game level. She lived in a rotten, mouldy, dark, half-abandoned condo building. She was also a terrible hoarder. I approach the old wooden door of her flat. It was painted over 1000 times and was barely closing. She knew I would come. She rushed outside, looked at me with her moon-sized eyes, grabbed my arm and told me:
“We have to run.”

I felt a sudden crippling rush of anxiety. I woke up. My heart was absolutely racing. My sight became darker and darker. The chest pain was consuming me, and I could barely move. I almost vomited.

That was quite a night.

Hi devs!
I've seeked the world but found no answer to this:
I want an android code to convert double[] to a sound file and be able to get that double[] from the file.
And yes I've tried stdAudio library but it did not work as I expected.

Give a replay, save my life 😁

My friend recently went through technical interview for a very specific position in very niche technology. Which I will call technology A.
He is an expert in technology A, but interview was in technology B. All questions were about technology B, which has very little to do with technology A.
After few days, my friend received written replay. In section about technical knowledge about technology A, interview wrote his opinion based on technology B. Even if he didn't ask any question related to technology A, because he has never heard of it. Of course my friend didn't get that job

# Retrospective as Backend engineer

Once upon a time, I was rejected by a startup who tries to snag me from another company that I was working with.
They are looking for Senior / Supervisor level backend engineer and my profile looks like a fit for them.
So they contacted me, arranged a technical test, system design test, and interview with their lead backend engineer who also happens to be co-founder of the startup.

## The Interview

As usual, they asked me what are my contribution to previous workplace.
I answered them with achievements that I think are the best for each company that I worked with, and how to technologically achieve them.

One of it includes designing and implementing a `CQRS+ES` system in the backend.
With complete capability of what I `brag` as `Time Machine` through replaying event.

## The Rejection

And of course I was rejected by the startup, maybe specifically by the co-founder. As I asked around on the reason of rejection from an insider.

They insisted I am a guy who overengineer thing that are not needed, by doing `CQRS+ES`, and only suitable for RND, non-production stuffs.

Nobody needs that kind of `Time Machine`.

## Ironically

After switching jobs (to another company), becoming fullstack developer, learning about react and redux.
I can reflect back on this past experience and say this:

The same company that says `CQRS+ES` is an over engineering, also uses `React+Redux`.
Never did they realize the concept behind `React+Redux` is very similar to `CQRS+ES`.

- Separation of concern
- CQRS: `Command` is separated from `Query`
- Redux: Side effect / `Action` in `Thunk` separated from the presentation
- Managing State of Application
- ES: Through sequence of `Event` produced by `Command`
- Redux: Through action data produced / dispatched by `Action`
- Replayability
- ES: Through replaying `Event` into the `Applier`
- Redux: Through replay `Action` which trigger dispatch to `Reducer`

---

The same company that says `CQRS` is an over engineering also uses `ElasticSearch+MySQL`.
Never did they realize they are separating `WRITE` database into `MySQL` as their `Single Source Of Truth`, and `READ` database into `ElasticSearch` is also inline with `CQRS` principle.

## Value as Backend Engineer

It's a sad days as Backend Engineer these days. At least in the country I live in.
Seems like being a backend engineer is often under-appreciated.
Company (or people) seems to think of backend engineer is the guy who ONLY makes `CRUD` API endpoint to database.

- I've heard from Fullstack engineer who comes from React background complains about Backend engineers have it easy by only doing CRUD without having to worry about application.
- The same guy fails when given task in Backend to make a simple round-robin ticketing system.
- I've seen company who only hires Fullstack engineer with strong Frontend experience, fails to have basic understanding of how SQL Transaction and Connection Pool works.
- I've seen company Fullstack engineer relies on ORM to do super complex query instead of writing proper SQL, and prefer to translate SQL into ORM query language.
- I've seen company Fullstack engineer with strong React background brags about Uncle Bob clean code but fail to know on how to do basic dependency injection.
- I've heard company who made webapp criticize my way of handling `session` through http secure cookie. Saying it's a bad practice and better to use local storage. Despite my argument of `secure` in the cookie and ability to control cookie via backend.

youtube's autoplay algorithm has made me discover some interesting gems on the internet.

but fucking damn it if it doesn't like to replay the same 15 songs you like. every fucking time.

like you know I like this band. SHOW ME OTHER SONGS OF THIS BAND GOD FUCKING DAMMIT. I KNOW I LIKE THESE 5 SONGS ALREADY.

Me: "I wanna mod Ikemen so it can have tag presets, a replay recording manager, a player card for online games, a gallery,..."
Windows: takes a whole day to update
Me: "I wanna mod Ikemen so it runs on Ubuntu"

My math teacher.

Simple story: His way of teaching was like bible study - he dictates the mathematical rules, the students had to write it down _exactly_ as told.
(Yes. He even dictated spaces / newlines / ....).

Had him for many years....
Since I was the rotten apple in class (I was always very weak regarding math), he had joy in mobbing me specifically.

It was one of the reasons I never thought about programming at all - or to be more precise, I _feared_ programming since everyone told me it would require intense knowledge of math.

Well. Fast forward. I went to university despite my fear, just because I was too stubborn to prove my math teacher right.

He was one of the counseling teachers too - and he made _very_ clear that I would fail in _anything_ regarding mathematics job wise.

I failed university, yes.

I gave up simply because I was too bored to learn and replay stuff by heart you'll certainly never need to remember your whole life.

Math played a role, too. Since I lacked the whole mathematical background, I barely passed the tests (mostly by a point).

But thanks to a lot of friends I learned that mathematics is helpful for programming - but not a must.

After giving up university, I started an apprenticeship.

And while I dreaded the decision for a long time, I couldn't be more happy about it.

New excuse for not doing work:
"taking data"

My dev system is tied up taking data for an hour to store data for a replay system I intend to build. I need raw data from the system. I need to know how much data I will collect in an hour as well. I also need to collect said data. For about an hour. This data will be fed back into the system sans the data collection. This will allow me to replay whole jobs that our field techs perform. If they get me data I can reprocess the data and fix my positioning algorithms. Kinda fun!

So the excuses are now up to 2:
"compiling"
and
"taking data"

Who else woke up at 6am to watch the Olympic live stream so to avoid ads during the primetime replay?

And now it seems to be over (8:30)...

Time for a 30min power nap before I head into work.

I got really interested in computers from gaming. Starting back with dial up Doom games with my friends to Team Fortress Classic clan matches. I recently downloaded Diablo 2 to replay it. The C++ class I took in High School solidified my fascination with coding. I quickly moved on to learning web coding and creating my own websites. Now it's a job I love.

oh boy can't wait to use the new Action Replay function they added in Teamviewer

EDIT: sorry for low-quality capture lol whoops

Is anyone around experienced with SDR, especially the HackRF?

I am trying to send OOK data at a certain frequency but it doesn't work. I am basically recording the wave, then using ooktools to decode the wave to binary and the hackrf_ook to send the binary. It doesn't work...

Using GNURadio for replay attacks works great, since I am not testing it on a rolling code device.

Has anyone managed to transmit binary (or hex) with the HackRF or any other SDR as a matter of fact? I cant use rfcat with the HackRF.

Some words just aren't the same anymore. Sometimes i replay in a dumb manner.

Don't you love it when a module maintainer replay for install instruction is "If there any specific things you think should be improved in the README or the help, please file a patch :)" What a dumb fuck you have to be to act that way??
