Its Friday, you all know what that means! ... Its results day for practiseSafeHex's most incompetent co-worker!!!

*audience: wwwwwwooooooooo!!!!*

We've had a bewildering array of candidates, lets remind ourselves:

- a psychopath that genuinely scared me a little
- a CEO I would take pleasure seeing in pain
- a pothead who mistook me for his drug dealer
- an unbelievable idiot
- an arrogant idiot obsessed with strings

Tough competition, but there can be only one ... *drum roll* ... the winner is ... none of them!

*audience: GASP!*
*audience member: what?*
*audience member: no way!*
*audience member: your fucking kidding me!*

Sir calm down! this is a day time show, no need for that ... let me explain, there is a winner ... but we've kept him till last and for a good reason

*audience: ooooohhhhh*

You see our final contestant and ultimate winner of this series is our good old friend "C", taking the letters of each of our previous contestants, that spells TRAGIC which is the only word to explain C.

*audience: laughs*

Oh I assure you its no laughing matter. C was with us for 6 whole months ... 6 excruciatingly painful months.

Backstory:

We needed someone with frontend, backend and experience with IoT devices, or raspberry PI's. We didn't think we'd get it all, but in walked an interviewee with web development experience, a tiny bit of Angular and his masters project was building a robot device that would change LED's depending on your facial expressions. PERFECT!!!

... oh to have a time machine

Working with C:

- He never actually did the tutorials I first set him on for Node.js and Angular 2+ because they were "too boring". I didn't find this out until some time later.

- The first project I had him work on was a small dashboard and backend, but he decided to use Angular 1 and a different database than what we were using because "for me, these are easier".

- He called that project done without testing / deploying it in the cloud, despite that being part of the ticket, because he didn't know how. Rather than tell or ask anyone ... he just didn't do it and moved on.

- As part of his first tech review I had to explain to him why he should be using if / else, rather than just if's.

- Despite his past experience building server applications and dashboards (4 years!), he never heard of a websocket, and it took a considerable amount of time to explain.

- When he used a node module to open a server socket, he sat staring at me like a deer caught in headlights completely unaware of how to use / test it was working. I again had to explain it and ultimately test it for him with a command line client.

- He didn't understand the need to leave logging inside an application to report errors. Because he used to ... I shit you not ... drive to his customers, plug into their server and debug their application using a debugger.

... props for using a debugger, but fuck me.

- Once, after an entire 2 days of tapping me on the shoulder every 15 mins for questions / issues, I had to stop and ask:

Me: "Have you googled it?"
C: "... eh, no"
Me: "can I ask why?"
C: "well, for me, I only google for something I don't know"
Me: "... well do you know what this error message means?"
C: "ah good point, i'll try this time"

... maybe he was A's stoner buddy?

- He burned through our free cloud usage allowance for a month, after 1 day, meaning he couldn't test anything else under his account. He left an application running, broadcasting a lot of data. Turns out the on / off button on the dashboard only worked for "on". He had been killing his terminal locally and didn't know how to "ctrl + c a cloud app" ... so left it running. His intention was to restart the app every time you are done using it ... but forgot.

- His issue with the previous one ... not any of his countless mistakes, not the lack of even trying to make the button work, no, no, not for C. C's issue is the cloud is "shit" for giving us such little allowances. (for the record in a month I had never used more than 5%).

- I had to explain environment variables and why they are necessary for passwords and tokens etc. He didn't know it wasn't ok to commit these into GitHub.

- At his project meetups with partners I had to repeatedly ask him to stop googling gifs and pay attention to the talks.

- He complained that we don't have 3 hour lunch breaks like his last place.

- He once copied and pasted the same function 450 times into a file as a load test ... are loops too mainstream nowadays?

You see C is our winner, because after 6 painful months (companies internal process / requirements) he actually achieved nothing. I really mean that, nothing. Every thing was so broken, so insecure / wide open, built without any kind of common sense or standards I had to delete it all and start again ... it took me 2 weeks.

I hope you've all enjoyed this series and will join me in praying for the return of my sanity ... I do miss it a lot.

Yours truly,

Lately my mornings have started out with sitting on my front porch with a cup of coffee and a smoke for about 15 or 20 minutes scrolling through devrant.
Probably why ive been in a better mood these days

It finally hit me the other day.
I'm working on an IoT project for a late-stage ALS patient. The setup is that he has a tablet he controls with his eye movements, and he wants to be able to control furnishings in his room without relying on anyone else.
I set up a socket connection between his tablet and the Raspberry Pi. From there it was a simple matter of using GPIO to turn a lamp or fan on or off. I did the whole thing in C, even the socket programming on the Pi.
As I was finishing up the main control of the program on the Pi I realized that I need to be more certain of this than anything I've ever done before.
If something breaks, the client may be forced to go days without being able to turn his room light on, or his fan off.
Understand he is totally trapped in his own body so it's not like he can simply turn the fan off. The nursing staff are not particularly helpful and his wife is tied up a lot with work and their two small children so she can't spend all day every day doting on him.
Think of how annoying it is when you're trying to sleep and someone turns the light on in your room; now imagine you can't turn it off yourself, and it would take you about twenty minutes to tell someone to turn it off -- that is once you get their attention, again without being able to move any part of your body except your eyes.
As programmers and devs, it's a skill to do thorough testing and iron-out all the bugs. It is an entirely different experience when your client will be depending on what you're doing to drastically improve his quality of life, by being able to control his comfort level directly without relying on others -- that is, to do the simplest of tasks that we all take for granted.
Giving this man some independence back to his life is a huge honor; however, it carries the burden of knowing that I need to be damned confident in what I am doing, and that I have designed the system to recover from any catastrophe as quickly as possible.

In case you were wondering how I did it all: The Pi launches a wrapper for the socket connection on boot.
The wrapper launches the actual socket connection in a child process, then waits for it to exit. When the socket connection exits, the wrapper analyzes the cause for the exit.
If the socket connection exited safely -- by passing a special command from the tablet to the Pi -- then the wrapper exits the main function, which allows updating the Pi. If the socket connection exited unexpectedly, then the Pi reboots automatically -- which is the fastest way to return functionality and to safeguard against any resource leaks.
The socket program itself launches its own child process, which is an executable on the Pi. The data sent by the tablet is the name of the executable on the Pi. This allows a dynamic number of programs that can be controlled from the tablet, without having to reprogram the Pi, except for loding the executable onto it. If this child of the socket program fails, it will not disrupt its parent process, which is the socket program itself.

I got back from my small 3 day vacation Sunday and I also decided to just take a break and relax before I hop back into my lil project I’m working on but it makes me feel like shit for taking so long to get back to it. Like I know I need breaks but I feel like I’m not good if I take breaks like this Idk don’t get me wrong I fuckin love programming more than anything but i just don’t want to force myself to work on something even if I do love it.
