You know side projects? Well I took on one. An old customer asked to come and take over his latest startups companys tech. Why not, I tought. Idea is sound. Customer base is ripe and ready to pay.
I start digging and the Hardware part is awesome. The guys doing the soldering and imbedded are geniuses. I was impressed AF.
I commit and meet up with CEO. A guy with a vision and sales orientation/contacts. Nice! This shit is gonna sell. Production lines are also set.
Website? WTF is this shit. Owner made it. Gotta give him the credit. Dude doesn't do computers and still managed to online something. He is still better at sales so we agree that he's gonna stick with those and I'll handle the tech.
I bootstrap a new one in my own simplistic style and online it. I like it. The owner likes it. He made me to stick to a tacky logo. I love CSS and bootstrap. You can make shit look good quick.
But I still don't have access to the soul of the product. DBs millions rows of data and source for the app I still behind the guy that has been doing this for over a year.
He has been working on a new version for quite some time. He granted access to the new versions source, but back end and DB is still out of reach. Now for over month has passed and it's still no new version or access to data.
Source has no documentation and made in a flavor of JS frame I'm not familiar with. Weekend later of crazy cramming I get up to speed and it's clear I can't get further without the friggin data.
The V2 is a scramble of bleeding edge of Alpha tech that isn't ready for production and is clearly just a paid training period for the dev. And clearly it isn't going so well because release is a month late. I try to contact, but no reaction. The owner is clueless.
Disheartening. A good idea is going to waste because of some "dev" dropping a ball and stonewalling the backup.
I fucking give him till the end of the next week until I make the hardware team a new api to push the data and refactor the whole thing in proper technologies and cut him off.
Please. If you are a dev and don't have the time to concentrate on the solution don't take it on and kill off the idea. You guys are the key to making things happening and working. Demand your cut but also deserve it by delivering or at least have the balls to tell you are not up for it. -
Wow... this is the perfect week for this topic.
Thursday, is the most fucked off I’ve ever been at work.
I’ll preface this story by saying that I won’t name names in the public domain to avoid anyone having something to use against me in court. But, I’m all for the freedom of information so please DM if you want to know who I’m talking about.
Yesterday I handed in my resignation, to the company that looked after me for my first 5 years out of university.
Thursday was my breaking point but to understand why I resigned you need a little back story.
I’m a developer for a corporate in a team of 10 or so.
The company that I work for is systemically incompetent and have shown me this without fail over the last 6 months.
For the last year we’ve had a brilliant contracted, AWS Certified developer who writes clean as hell hybrid mobile apps in Ion3, node, couch and a tonne of other up to the minute technologies. Shout out to Morpheus you legend, I know you’re here.
At its core my job as a developer is to develop and get a product into the end users hands.
Morpheus was taking some shit, and coming back to his desk angry as fuck over the last few months... as one of the more experienced devs and someone who gives a fuck I asked him what was up.
He told me, company want their mobile app that he’s developed on internal infrastructure... and that that wasn’t going to work.
Que a week of me validating his opinion, looking through his work and bringing myself up to speed.
I came to the conclusion that he’d done exactly what he was asked to, brilliant Work, clean code, great consideration to performance and UX in his design. He did really well. Crucially, the infrastructure proposed was self-contradicting, it wouldn’t work and if they tried to fudge it in it would barely fucking run.
So I told everyone I had the same opinion as him.
4 months of fucking arguing with internal PMs, managers and the project team go by... me and morpheus are told we’re not on the project.
The breaking point for me came last Wednesday, given no knowledge of the tech, some project fannies said Morpheus should be removed and his contract terminated.
I was up in fucking arms. He’d done everything really well, to see a fellow developer take shit for doing his job better than anyone else in [company] could was soul destroying.
That was the straw on the camels back. We don’t come to work to take shit for doing a good job. We don’t allow our superiors to give people shit in our team when they’re doing nothing but a good job. And you know what: the opinion of the person that knows what they’re talking about is worth 10 times that of the fools who don’t.
My manager told me to hold off, the person supposed to be supporting us told me to stand down. I told him I was going to get the app to the business lead because he fucking loves it and can tell us if there’s anything to change whilst architecture sorts out their outdated fucking ideas.
Stand down James. Do nothing. Don’t do your job. Don’t back Morpheus with his skills and abilities well beyond any of ours. Do nothing.
That was the deciding point for me, I said if Morpheus goes... I go... but then they continued their nonsense, so I’m going anyway.
I made the decision Thursday, and Friday had recruiters chomping at the bit to put the proper “senior” back in my title, and pay me what I’m worth.
The other issues that caused me to see this company in it’s true form:
- I raised a key security issue, documented it, and passed it over to the security team.
- they understood, and told the business users “we cannot use ArcGIS’ mobile apps, they don’t even pretend to be secure”
- the business users are still using the apps going into the GDPR because they don’t understand the ramifications of the decisions they’re making.
I noticed recently that [company] is completely unable to finish a project to time or budget... and that it’s always the developers put to blame.
I also noticed that middle management is in a constant state of flux with reorganisations because in truth the upper managers know they need to sack them.
For me though, it was that developers in [company], the people that know what they’re talking about; are never listened to.
Fuck being resigned to doing a shit job.
Fuck this company. On to one that can do it right.
Morpheus you beautiful bastard I know you’ll be off soon too but I also feel I’ve made a friend for life. “Private cloud” my arse.
Since making the decision Thursday I feel a lot more free, I have open job offers at places that do this well. I have a position of power in the company to demand what I need and get it. And I have the CEO and CTO’s ears perking up because their department is absolutely shocking.
Freedom is a wonderful feeling.13 -
My first AI program in the 1985 on Apple IIe (64kb ram computer) was answering simple questions with yes and no. Everyone were shocked with precision of about 100% when I was typing and 70-80% when others were typing. My parents were scared and skeptical. How it works? Store the time between the first key pressure and the following, when it is larger than 1 second the answer is yes, otherwise no. They say the question, you know the answer and type accordingly. When they want to write the question themselves, you try to force their typing speed if possible. I was 12 years old and it was very funny.3

Since I'm working for 3 years as a parttime software engineer, I started to feel my tendon sheath more and more, sometimes it was hurting so I decided to have a look around on ergonomic keyboards, because in the office we only have these flat, thin wireless keyboards which are the fucking opposite of ergonomic.
They feel like when Eddie Scissorhands has to cut hair of a pile of rocks.
So after some reviews I decided to buy a Kinesis Advantage2 (made in the USA of Americas) eventhough it is quite expensive (379 Kanuckistan Kopeks).
I must say this keyboard is fucking well engineered. You can remap every key in a few keypresses and it is stored on the keyboard itself, no software required... awesome!
The disadvantage for me is, being pretty tall I have very wide shoulders so the 2 keyboard pits are a bit too close together in my oppinion.
The other thing is, you really have to get used to it... I am slowly advancing in speed and it feels great. No pain anymore and I don't have to move my hands at all.
So what are your experiences with keyboards and does your workplace have a good setup for staying healthy?19 -
Recently for a project I needed to read/write ID3 tags from MP3 files. And after a long search, I found this bloated, monolithic but quite stable library, "getID3".
So, I was looking through the code-base and I found this. This guy literally storing the key value based data embedded as comments within the class file. Then wrote a method to parse the data and even used caching to ensure maximum speed! And such usage is repeated all over the code-base.
So, this is what people used do before arrays were invented :314 -
2020 seems to be the year of the "dev who has never seen scale."
TypeA -> "Here's a reasoned explanation for a change I think we should make. Here is the current deficiency analysis, here is the desired resolution, here is the course of action and all calculations leading to the resolution + data. This will have x,y,z beneficial result according to our operational metrics."
TypeD -> "Those were words. Why do you need that? Change is bad, learning is worse. This will just slow me down, development speed is all that matters; there is no chance that a poorly considered/factored/checked design could ever require a ground up rewrite or fuck us utterly in the long term. Why do you make my life harder? We could x -> y -> zBUTI haven't done the math and I really don't see the benefit in x, so z is pointless. What even is scale?"
The consequences of the war caused by the ever-widening gap between engineers and developers is low key terrifying.12 -
So recently I installed Windows 7 on my thiccpad to get Hyperdimension Neptunia to run (yes 50GB wasted just to run a game)... And boy did I love the experience.
ThinkPads are business hardware, remember that. And it's been booting Debian rock solid since.. pretty much forever. There are no hardware issues here. Just saying.
With that out of the way I flashed Windows 7 Ultimate on a USB stick and attempted to boot it... Oh yay, first hurdle to overcome. It can't boot in UEFI mode. Move on Debian, you too shall boot in BIOS mode now! But okay, whatever right. So I set it to BIOS mode and shuffled Debian's partitions around a bit to be left with 3 partitions where Windows could stick in one more.
Installed, it asks for activation. Now my ThinkPad comes with a Windows 7 Pro license key, so fuck it let's just use that and Windows will be able to disable the features that are only available for Ultimate users, right? How convenient would that be, to have one ISO for all the half a dozen editions that each Windows release has? And have the system just disable (or since we're in the installer anyway, not install them in the first place) features depending on what key you used? Haha no, this is Microsoft! Developers developers developers DEVELOPERS!!! Oh and Zune, if anyone remembers that clusterfuck. Crackhead Microsoft.
But okay whatever, no activation then and I'll just fetch Windows Loader from my webserver afterwards to keygen my way through. Too bad you didn't accept that key Microsoft! Wouldn't that have been nice.
So finally booted into the installed system now, and behold finally we find something nice! Apparently Windows 7 Enterprise and Ultimate offer a native NFS driver. That's awesome! That way I don't have to adjust my file server at all. Just some fuckery with registry keys to get the UID and GID correct, but I'll forgive it for that. It's not exactly "native" to Windows after all. The fact that it even has a built-in driver for it is something I found pretty neat already.
Fast-forward a few hours and it's time to Re Boot.. drivers from Lenovo that required reboots and whatnot. Fire the system back up, and low and behold the network drive doesn't mount anymore. I've read that this is apparently due to Windows (not always but often) mounting the network drive before the network comes up. Absolutely brilliant! Move out shitstaind, have you seen this beauty of an init Mr. Poet?
But fuck it we can mount that manually after every single boot.. you know, convenient like that. C O P E.
With it now manually mounted, let's watch a movie! I've recently seen Pyro's review on The Platform and I absolutely loved it. The movie itself is quite good too. Open the directory on my file server and.. oh. Windows.. you just put db.thumb on it and db.thumb:encryptable. I shit you not, with the colon and everything. I thought that file names couldn't contain colons Windows! I thought that was illegal in NTFS. Why you doing this in NFS mate? And "encryptable", am I already infected with ransomware??? If it wasn't for the fact that that could also be disabled with something as easy as a registry key, I would've thought I contracted ransomware!
Oh and sound to go with that video, let's pair up some Bluetooth headphones with that Bluetooth driver I installed earlier! Except.. haha nope. Apparently you don't get that either.
Right so let's just navigate the system in its Aero glory... Gonna need to flick the mouse for that. Except it's excruciatingly slow, even the fastest speed is slower than what I'm used to on Linux.. and it's jerky as hell (Linux doesn't have any of that at higher speed). But hey it can compensate for that! Except that slows down the mouse even more. And occasionally the mouse driver gets fucked up too. Wanna scroll on Telegram messages in a chat where you're admin? Well fuck you mate, let me select all these messages for you and auto scroll at supersonic speeds! And God forbid that you press delete with that admin access of yours. Oh maybe I'll do it for you, helpful OS I am!
And the most saddening part of it all? I'd argue that Windows 7 is the best operating system that Microsoft ever released. Yeah. That's the best they could come up with. But at least it plays le games!10 -
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?8 -
Tabs, or No Tabs? I did the same as this commentor 2 years ago. I can code so quick now because of this simple switch. Here's why:
(source, Laracasts.com)
Ben Smith
"I think the most beneficial tip was to do away with tabs. Although it took a while to get used to and on many occasions in the first few days I almost switched them back on, it has done wonders for my workflow.
I find it keeps my brain more engaged with the task at hand due to keeping the editor (and my mind) clutter free. Before when I had to refer to a class, I would have opened it in a new tab and then I might have left it open to make it easier to get to again. This would quickly result in a bar full of tabs and navigation around the editor would become slow and my brain would get bogged down keeping track of what was open and which tab it was in. With the removal of the tab bar I'm now able to keep only the key information in my mind and with the ability to quickly switch between recently opened files, I find I haven't lost any of the speed which I initially thought I might.
In fact this is something I have noticed in all areas of writing code, the more proficient I have become with an editor the better the code I have been writing. Any time spent actually writing your code is time in which your brain is disconnected from the problem you are trying to solve. The quicker you are able to implement your ideas in code, the smaller the disconnect becomes. For example, I have recently been learning how to do unit testing and to do so I have been rewriting an old project with tests included. The ability to so quickly refactor has meant that whereas before I might have taken 30 seconds shuffling code around, now I can spend maybe 5 seconds allowing my mind to focus much better on how best to refactor, not on the actual process of doing so."
jeff_way Mod
"Yeah - it takes a little while to get used to the idea of having no tabs. But, I wouldn't go back at this point. It's all about forcing yourself into a faster workflow. If you keep the tabs and the sidebar open, you won't use the keyboard."2 -
After learning a bit about alife I was able to write
another one. It took some false starts
to understand the problem, but afterward I was able to refactor the problem into a sort of alife that measured and carefully tweaked various variables in the simulator, as the algorithm
explored the paramater space. After a few hours of letting the thing run, it successfully returned a remainder of zero on 41.4% of semiprimes tested.
This is the bad boy right here:
tracks[14]
[15, 2731, 52, 144, 41.4]
As they say, "he ain't there yet, but he got the spirit."
A 'track' here is just a collection of critical values and a fitness score that was found given a few million runs. These variables are used as input to a factoring algorithm, attempting to factor
any number you give it. These parameters tune or configure the algorithm to try slightly different things. After some trial runs, the results are stored in the last entry in the list, and the whole process is repeated with slightly different numbers, ones that have been modified
and mutated so we can explore the space of possible parameters.
Naturally this is a bit of a hodgepodge, but the critical thing is that for each configuration of numbers representing a track (and its results), I chose the lowest fitness of three runs.
Meaning hypothetically theres room for improvement with a tweak of the core algorithm, or even modifications or mutations to the
track variables. I have no clue if this scales up to very large semiprime products, so that would be one of the next steps to test.
Fitness also doesn't account for return speed. Some of these may have a lower overall fitness, but might in fact have a lower basis
(the value of 'i' that needs to be found in order for the algorithm to return rem%a == 0) for correctly factoring a semiprime.
The key thing here is that because all the entries generated here are dependent on in an outer loop that specifies [i] must never be greater than a/4 (for whatever the lowest factor generated in this run is), we can potentially push down the value of i further with some modification.
The entire exercise took 2.1735 billion iterations (3-4 hours, wasn't paying attention) to find this particular configuration of variables for the current algorithm, but as before, I suspect I can probably push the fitness value (percentage of semiprimes covered) higher, either with a few
additional parameters, or a modification of the algorithm itself (with a necessary rerun to find another track of equivalent or greater fitness).
I'm starting to bump up to the limit of my resources, I keep hitting the ceiling in my RAD-style write->test->repeat development loop.
I'm primarily using the limited number of identities I know, my gut intuition, combine with looking at the numbers themselves, to deduce relationships as I improve these and other algorithms, instead of relying strictly on memorizing identities like most mathematicians do.
I'm thinking if I want to keep that rapid write->eval loop I'm gonna have to upgrade, or go to a server environment to keep things snappy.
I did find that "jiggling" the parameters after each trial helped to explore the parameter
space better, so I wrote some methods to do just that. But what I wouldn't mind doing
is taking this a bit of a step further, and writing some code to optimize the variables
of the jiggle method itself, by automating the observation of real-time track fitness,
and discarding those changes that lead to the system tending to find tracks with lower fitness.
I'd also like to break up the entire regime into a training vs test set, but for now
the results are pretty promising.
I knew if I kept researching I'd likely find extensions like this. Of course tested on
billions of semiprimes, instead of simply millions, or tested on very large semiprimes, the
effect might disappear, though the more i've tested, and the larger the numbers I've given it,
the more the effect has become prevalent.
Hitko suggested in the earlier thread, based on a simplification, that the original algorithm
was a tautology, but something told me for a change that I got one correct. Without that initial challenge I might have chalked this up to another false start instead of pushing through and making further breakthroughs.
I'd also like to thank all those who followed along, helped, or cheered on the madness:

Wait, so pressing a key on a modern system and it showing up on screen is slower than it was back in the 70s and 80s because the ratio of transistors to clock speed is worse?
