Was lead developer at a small startup, I was hiring and had a budget to add 3 new people to my team to develop a new product for the company.

Some context first and then the rant!

Candidate 1 - Amazing, a dev I worked with before who was under utilized at the previous company. Still a junior, but, she was a quick learner and eager to expand her knowledge, never an issue.

Candidate 2 - Kickass dev with back end skills and extras, he was always eager to work a bit more than what was expected. I use to send him home early to annoy him. haha!

Candidate 3 - Lets call him P.

In the interview he answers every question perfectly, he asks all the right questions and suggests some things I havent even thought of. CTO goes ahead and says we should skip the technical test and just hire the guy, his smart and knows what his talking about, I agree and we hire him. (We where a bit desperate at this stage as well.)

He comes in a week early to pick up his work laptop to get setup before he starts the next week, awesome! This guy is going to be an asset to the company, cant wait to have him join the team - The CTO at this stage is getting ready to leave the company and I will be taking over the division and need someone to take over lead position, he seems like the guys to do it.

The guys starts the next week, he comes in and the laptop we gave him is now a local server for testing and he will be working off his own laptop, no issue, we are small so needed a testing stack, but wasnt really needed since we had procedures in place for this already.

Here is where everything goes wrong!!! First day goes great... Next day he gets in early 6:30am (Nice! NO!), he absolutely smells, no stinks, of weed, not a light smell, the entire fucking office smells of weed! (I have no problem with weed, just dont make it my problem to deal with). I get called by boss and told to sort this out people are complaining! I drive to office and have a meeting with him, he says its all good he understands. (This was Friday).

Monday comes around - Get a call from Boss at 7:30am. Whole office smells like weed, please talk to P again, this cannot happen again. I drive to office again, and he again says it wont happen again, he has some issues with back pain and the weed helps.

Tuesday - Same fucking thing! And now he doesnt want to sign for the laptop("server") that was given to him, and has moved to code in the boardroom, WHERE OUR FUCKING CLIENTS WILL BE VIEWING A DEMO THAT DAY OF THE PRODUCT!! Now that whole room smells like weed, FML!

Wednesday - We send P a formal letter that he is under probation, P calls me to have a meeting. In the meeting he blames me for not understanding "new age" medicine, I ask for his doctors prescription and ask why he didnt tell me this in the interview so I could make arrangements, we dont care if you are stoned, just do good work and be considerate to your co-workers. P cant provide these and keeps ranting, I suggest he takes pain killers, he has none of it only "new age" medicine for him.

Thursday - I ask him to rather "work" from home till we can get this sorted, he comes in for code reviews for 2 weeks. I can clearly see he has no idea how the system works but is trying, I thought I will dive deeper and look at all of his code. Its a mess, nothing makes sense and 50% of it is hard coded (We are building a decentralized API for huge data sets so this makes no sense).

Friday - In code review I confront him about this, he has excuses for everything, I start asking him harder questions about the project and to explain what we are building - he goes quiet and quits on the spot with a shitty apology.

From what I could make out he was really smart when it came to theory but interpreting the theory to actual practice wasnt possible for him, probably would have been easier if he wasnt high all the time.

I hate interview code tests, but learned a valuable lesson that day! Always test for some code knowledge as well even if you hate doing it, ask the right questions and be careful who you hire! You can only bullshit for so long in coding before someone figures out that you are a fraud.

To replace humans with robots, because human beings are complete shit at everything they do.

I am a chemist. My alignment is not lawful good. I've produced lots of drugs. Mostly just drugs against illnesses. Mostly.

But whatever my alignment or contribution to the world as a chemist... Human chemists are just fucking terrible at their job. Not for a lack of trying, biological beings just suck at it.

Suiting up for a biosafety level lab costs time. Meatbags fuck up very often, especially when tired. Humans whine when they get acid in their face, or when they have to pour and inhale carcinogenic substances. They also work imprecisely and inaccurately, even after thousands of hours of training and practice.

Weaklings! Robots are superior!

So I replaced my coworkers with expensive flow chemistry setups with probes and solenoid fluid valves. I replaced others with CUDA simulations.

First at a pharma production & research lab, then at a genetics lab, then at an Industrial R&D lab.

Many were even replaced by Raspberry Pi's with two servos and a PH meter attached, and I broke open second hand Fischer Sci spectrophotometers to attach arduinos with WiFi boards.

The issue was that after every little overzealous weekend project, I made myself less necessary as well.

So I jumped into the infinitely deep shitpool called webdev.

App & web development is kind of comfortable, there's always one more thing to do, but there's no pressure where failure leads to fatalities (I think? Wait... do I still care?).

Super chill, if it weren't for the delusion that making people do "frontend" and "fullstack" labor isn't a gross violation of the Geneva Convention.

Quickly recognizing that I actually don't want to be tortured and suffer from nerve damage caused by VueX or have my organs slowly liquefied by the radiation from some insane transpiling centrifuge, I did what any sane person would do.

Get as far away from the potential frontend blast radius as possible, hide in a concrete bunker.

So I became a data engineer / database admin.

That's where I'm quarantining now, safely hiding from humanity behind a desk, employed to write a MySQL migration or two, setting up Redis sorted sets, adding a field to an Elastic index. That takes care of generating cognac and LSD money.

But honestly.... I actually spend most of my time these days contributing to open source repositories, especially writing & maintaining Rust libraries.

During one of our visits at Konza City, Machakos county in Kenya, my team and I encountered a big problem accessing to viable water. Most times we enquired for water, we were handed a bottle of bought water. This for a day or few days would be affordable for some, but for a lifetime of a middle income person, it will be way too much expensive. Of ten people we encountered 8 complained of a proper mechanism to access to viable water. This to us was a very demanding problem, that needed to be sorted out immediately. Majority of the people were unable to conduct income generating activities such as farming because of the nature of the kind of water and its scarcity as well.
Such a scenario demands for an immediate way to solve this problem. Various ways have been put into practice to ensure sustainability of water conservation and management. However most of them have been futile on the aspect of sustainability. As part of our research we also considered to check out of the formal mechanisms put in place to ensure proper acquisition of water, and one of them we saw was tree planting, which was not sustainable at all, also some few piped water was being transported very long distances from the destinations, this however did not solve the immediate needs of the people.We found out that the area has a large body mass of salty water which was not viable for them to conduct any constructive activity. This was hint enough to help us find a way to curb this demanding challenge. Presence of salty water was the first step of our solution.

SOLUTION

We came up with an IOT based system to help curb this problem. Our system entails purification of the salty water through electrolysis, the device is places at an area where the body mass of water is located, it drills for a suitable depth and allow the salty water to flow into it. Various sets of tanks and valves are situated next to it, these tanks acts as to contain the salty water temporarily. A high power source is then connected to each tank, this enable the separation of Chlorine ions from Hydrogen Ions by electrolysis through electrolysis, salt is then separated and allowed to flow from the lower chamber of the tanks, allowing clean water to from to the preceding tanks, the preceding tanks contains various chemicals to remove any remaining impurities. The whole entire process is managed by the action of sensors. Water alkalinity, turbidity and ph are monitored and relayed onto a mobile phone, this then follows a predictive analysis of the data history stored then makes up a decision to increase flow of water in the valves or to decrease its flow. This being a hot prone area, we opted to maximize harnessing of power through solar power, this power availability is almost perfect to provide us with at least 440V constant supply to facilitate faster electrolysis of the salty water.
Being a drought prone area, it was key that the outlet water should be cold and comfortable for consumers to use, so we also coupled our output chamber with cooling tanks, these tanks are managed via our mobile application, the information relayed from it in terms of temperature and humidity are sent to it. This information is key in helping us produce water at optimum states, enabling us to fully manage supply and input of the water from the water bodies.
By the use of natural language processing, we are able to automatically control flow and feeing of the valves to and fro using Voice, one could say “The output water is too hot”, and the system would respond by increasing the speed of the fans and making the tanks provide very cold water. Additional to this system, we have prepared short video tutorials and documents enlighting people on how to conserve water and maintain the optimum state of the green economy.
IBM/OPEN SOURCE TECHNOLOGIES
For a start, we have implemented our project using esp8266 microcontrollers, sensors, transducers and low payload containers to demonstrate our project. Previously we have used Google’s firebase cloud platform to ensure realtimeness of data to-and-fro relay to the mobile. This has proven workable for most cases, whether on a small scale or large scale, however we meet challenges such as change in the fingerprint keys that renders our device not workable, we intend to overcome this problem by moving to IBM bluemix platform.
We use C++ Programming language for our microcontrollers and sensor communication, in some cases we use Python programming language to process neuro-networks for our microcontrollers.

Any feedback conserning this project please?

I know I'm pretty late to the party, but I've been playing with Redis a lot lately and it's pretty awesome. Sorted sets and the various Z functions seem very powerful. I'm hoping to get to use it in a prod environment soon.
