One of our web developers reported a bug with my image api that shrunk large images to a thumbnail size. Basically looked like this img = ResizeImage(largeImage, 50); // shrink the image by 50%
The 'bug' was when he was passed in the thumbnail image and requesting a 300% increase, and the image was too pixelated.
I tried to explain that if you need the larger image, use the image from disk (since the images were already sized optimally for display) and the api was just for resizing downward.
Thinking I was done, the next day I was called into a large conference room with the company vice-president, two of the web-dev managers, and several of the web developers.
VP: "I received an alarming email saying you refused to fix that bug in your code. Is that correct?"
Me: "Bug? No, there is no bug. The image api is executing just as it is supposed to."
MGR1: "Uh...no it isn't. Images using *your* code is pixelated and unfit for our site and our customers."
MGR2: "Yes, I looked at your code and don't understand what the big deal is. Looks like a simple fix."
<web developers nodding their heads>
Me: "OK, I'll bite. What is the simple fix?"
<MGR2 looks over at one of the devs>
Dev1: "Well, for example, if we request an image resize of 300, and the image is only 50x50, only increase the size by 10. Maybe 15."
Me: "Wow..OK. So what if the image is, for example, 640x480?"
MGR1: "75. Maybe 80 if it's a picture of boots."
VP: "Oh yes, boots. We need good pictures of boots."
Me: "I'm not exactly sure how to break this to you, but my code doesn't do 'maybe'. I mean, you have the image from disk.
You obviously used the api to create the thumbnail, but are trying to use the thumbnail to go back to the regular size. Why not use the original image?"
<Web-Dev managers look awkwardly towards the web devs>
Dev3: "Yea, well uh...um...that would require us to create a variable or something to store the original image. The place in the code where we need the regular image, it's easier to call your method."
Me: "Um, not really. You still have to resolve the product name from the URL path. Deriving the original file name is what you are doing already. Just do the same thing in your part of the code."
Dev2: "But we'd have to change our code"
Mgr2: "I know..I know. How about if we, for example, send you 12345.jpg and request a resize greater than 100, you go to disk and look for that image?"
<VP, mgrs, and devs nod happily>
Me: "Um, no that won't work. All I see is the image stream. I have no idea what file is and the api shouldn't be guessing, going to disk or anything like that."
Dev1: "What if we pass you the file name?"
<VP, mgrs, and devs nod happily again>
Me: "No, that would break the API contract and ...uh..wait...I'm familiar with your code. How about I make the change? I'm pretty sure I'll only have to change one method"
VP: "What! No...it’s gotta be more than that. Our site is huge."
<Mgrs and devs grumble and shift around in their chairs>
Me: "I'm done talking about this. I can change your code for you or you can do it. There is no bug and I'm not changing the api because you can't use it correctly."

Later I discovered they stopped using the resize api and wrote dynamic html to 'resize' the images on the client (download the 5+ meg images, and use the length and width properties)

You know who sucks at developing APIs?

Facebook.

I mean, how are so high paid guys with so great ideas manage to come up with apis THAT shitty?

Let's have a look. They took MVC and invented flux. It was so complicated that there were so many overhyped articles that stated "Flux is just X", "Flux is just Y", and exactly when Redux comes to the stage, flux is forgotten. Nobody uses it anymore.

They took declarative cursors and created Relay, but again, Apollo GraphQL comes and relay just goes away. When i tried just to get started with relay, it seemed so complicated that i just closed the tab. I mean, i get the idea, it's simple yet brilliant, but the api...

Immutable.js. Shitload of fuck. Explain WHY should i mess with shit like getIn(path: Iterable<string | number>): any and class List<T> { push(value: T): this }? Clojurescript offers Om, the React wrapper that works about three times faster! How is it even possible? Clojure's immutable data structures! They're even opensourced as standalone library, Mori js, and api is great! Just use it! Why reinvent the wheel?

It seems like when i just need to develop a simple react app, i should configure webpack (huge fuckload of work by itself) to get hot reload, modern es and jsx to work, then add redux, redux-saga, redux-thunk, react-redux and immutable.js, and if i just want my simple component to communicate with state, i need to define a component, a container, fucking mapStateToProps and mapDispatchToProps, and that's all just for "hello world" to pop out. And make sure you didn't forget to type that this.handler = this.handler.bind(this) for every handler function. Or use ev closure fucked up hack that requires just a bit more webpack tweaks. We haven't even started to communicate to the server! Fuck!

I bet there is savage ass overengineer sitting there at facebook, and he of course knows everything about how good api should look, and he also has huge ass ego and he just allowed to ban everything that he doesn't like. And he just bans everything with good simple api because it "isn't flexible enough".

"React is heavier than preact because we offer isomorphic multiple rendering targets", oh, how hard want i to slap your face, you fuckface. You know what i offered your mom and she agreed?

They even created create-react-app, but state management is still up to you. And react-boierplate is just too complicated.

When i need web app, i type "lein new re-frame", then "lein dev", and boom, live reload server started. No config. Every action is just (dispatch) away, works from any component. State subscription? (subscribe). Isolated side-effects? (reg-fx). Organize files as you want. File size? Around 30k, maybe 60 if you use some clojure libs.

If you don't care about massive market support, just use hyperapp. It's way simpler.

Dear developers, PLEASE, don't forget about api. Take it serious, it's very important. You may even design api first, and only then implement the actual logic. That's even better.

And facebook, sincerelly,

Fuck you.

Time for an actual rant:

During an internship I heard from my PM that my assignment for the week after was going to be working on a specific sql query to add some features and fix some bugs.

When talking with colleagues about that assignment later, they laughed and referred to the query as the "query of doom" (QoD), naive as I was back then, I thought that one of my colleagues had the QoD displayed on his screen because the query he was working on looked rather large (about 20 lines). They all laughed and told me I was in for a treat.

Starting my assignment the week after I was horrified to find out the QoD was huge, and by huge I mean, printing that specific query resulted in 8 A4 pages font size 10, front and back.
There were over a 100 union statements, no proper aliases, no documentation, not a single foreign key in the entire database, naming that makes no sense. And everything written manually by 10 different developers over the past years, who all fell of the face of the earth.

And this was only the query of doom. The entire product was a complete clusterfuck of forms with a queries directly behind action buttons, because we weren't allowed to make classes (yes you read that correctly. We couldn't make classes, unless we had a very compelling reason). Everything was created by over 30 different devs who only managed to stay just long enough to get some work done.

And all of this was the result of a PM who didn't believe in frameworks, ORM's, OOP, classes, ... because that made the software slow. To this day he still manages that product, but I'm glad that I quickly decided to move on.

I very very rarely drink, but when I do I party hard.

I negotiated an entire piece of complex web architecture (really huge, works at 50k transactions per second), with my boss who's a lead architect, from a bar (he thought I was home), while moderately drunk.

It got me a lotta praise and till date it's one of the best pieces of software I've ever written. It saved the company 500+ hours or something #humblebrag.

To this day I have no recollection of what I said (huge hangover after) or how I managed to come up with that shit. I don't think I'd have been able to do it sober. The sheer size of the problem would've made me go "yea it works, I'm not touching that. Nope."

DAE notice any increase in pattern recognition in their code while drunk?

Almost 3 years ago I contacted an IT company that was looking for developers. The job listing was vague at best but it was a 10 man company with huge international clients for content migration and improvement.

I had basically no prior development experience but got invited to the interview regardless. I took a test in Java, first time I had seen the language but I finished it with some help from Google. At the time I was still a student so I couldn't work full time either.

Disregarding all that, the team lead advised the CEO to hire me regardless, so he did.

Forward to today.

I still proudly work for this company and have been responsible for a complete redesign of their flagship product. I learned a great deal about software development and developed an amazing relationship with most of the employees. The company has quadrupled in size since and we are moving to a bigger office start of next year.

Sometimes life gives you gold, not lemons.

Here are the reasons why I don't like IPv6.

Now I'll be honest, I hate IPv6 with all my heart. So I'm not supporting it until inevitably it becomes the de facto standard of the internet. In home networks on the other hand.. huehue...

The main reason why I hate it is because it looks in every way overengineered. Or rather, poorly engineered. IPv4 has 32 bits worth, which translates to about 4 billion addresses. IPv6 on the other hand has 128 bits worth of addresses.. which translates to.. some obscenely huge number that I don't even want to start translating.

That's the problem. It's too big. Anyone who's worked on the internet for any amount of time knows that the internet on this planet will likely not exceed an amount of machines equal to about 1 or 2 extra bits (8.5B and 17.1B respectively). Now of course 33 or 34 bits in total is unwieldy, it doesn't go well with electronics. From 32 you essentially have to go up to 64 straight away. That's why 64-bit processors are.. well, 64 bits. The memory grew larger than the 4GB that a 32-bit processor could support, so that's what happened.

The internet could've grown that way too. Heck it probably could've become 64 bits in total of which 34 are assigned to the internet and the remaining bits are for whatever purposes large IP consumers would like to use the remainder for.

Whoever designed IPv6 however.. nope! Let's give everyone a /64 range, and give them quite literally an IP pool far, FAR larger than the entire current internet. What's the fucking point!?

The IPv6 standard is far larger than it should've been. It should've been 64 bits instead of 128, and it should've been separated differently. What were they thinking? A bazillion colonized planets' internetworks that would join the main internet as well? Yeah that's clearly something that the internet will develop into. The internet which is effectively just a big network that everyone leases and controls a little bit of. Just like a home network but scaled up. Imagine or even just look at the engineering challenges that interplanetary communications present. That is not going to be feasible for connecting multiple planets' internets. You can engineer however you want but you can't engineer around the hard limit of light speed. Besides, are our satellites internet-connected? Well yes but try using one. And those whizz only a couple of km above sea level. The latency involved makes it barely usable. Imagine communicating to the ISS, the moon or Mars. That is not going to happen at an internet scale. Not even close. And those are only the closest celestial objects out there.

So why was IPv6 engineered with hundreds of years of development and likely at least a stage 4 civilization in mind? No idea. Future-proofing or poor engineering? I honestly don't know. But as a stage 0 or maybe stage 1 person, I don't think that I or civilization for that matter is ready for a 128-bit internet. And we aren't even close to needing so many bits.

Going back to 64-bit processors and memory. We've passed 32 bit address width about a decade ago. But even now, we're only at about twice that size on average. We're not even close to saturating 64-bit address width, and that will likely take at least a few hundred years as well. I'd say that's more than sufficient. The internet should've really become a 64-bit internet too.

So... the US Govt. just released a shit ton of files on JFK assasination, and being the data hoarder that I am, I promptly requested a bulk download link...
Apparently I underestimated the "shit ton" part, coz each of these files is around 2.4GBs... and I dont have the data to download them :-D :-D
FML

I've found and fixed any kind of "bad bug" I can think of over my career from allowing negative financial transfers to weird platform specific behaviour, here are a few of the more interesting ones that come to mind...

#1 - Most expensive lesson learned

Almost 10 years ago (while learning to code) I wrote a loyalty card system that ended up going national. Fast forward 2 years and by some miracle the system still worked and had services running on 500+ POS servers in large retail stores uploading thousands of transactions each second - due to this increased traffic to stay ahead of any trouble we decided to add a loadbalancer to our backend.

This was simply a matter of re-assigning the IP and would cause 10-15 minutes of downtime (for the first time ever), we made the switch and everything seemed perfect. Too perfect...

After 10 minutes every phone in the office started going beserk - calls where coming in about store servers irreparably crashing all over the country taking all the tills offline and forcing them to close doors midday. It was bad and we couldn't conceive how it could possibly be us or our software to blame.

Turns out we made the local service write any web service errors to a log file upon failure for debugging purposes before retrying - a perfectly sensible thing to do if I hadn't forgotten to check the size of or clear the log file. In about 15 minutes of downtime each stores error log proceeded to grow and consume every available byte of HD space before crashing windows.

#2 - Hardest to find

This was a true "Nessie" bug.. We had a single codebase powering a few hundred sites. Every now and then at some point the web server would spontaneously die and vommit a bunch of sql statements and sensitive data back to the user causing huge concern but I could never remotely replicate the behaviour - until 4 years later it happened to one of our support staff and I could pull out their network & session info.

Turns out years back when the server was first setup each domain was added as an individual "Site" on IIS but shared the same root directory and hence the same session path. It would have remained unnoticed if we had not grown but as our traffic increased ever so often 2 users of different sites would end up sharing a session id causing the server to promptly implode on itself.

#3 - Most elegant fix

Same bastard IIS server as #2. Codebase was the most unsecure unstable travesty I've ever worked with - sql injection vuns in EVERY URL, sql statements stored in COOKIES... this thing was irreparably fucked up but had to stay online until it could be replaced. Basically every other day it got hit by bots ended up sending bluepill spam or mining shitcoin and I would simply delete the instance and recreate it in a semi un-compromised state which was an acceptable solution for the business for uptime... until we we're DDOS'ed for 5 days straight.

My hands were tied and there was no way to mitigate it except for stopping individual sites as they came under attack and starting them after it subsided... (for some reason they seemed to be targeting by domain instead of ip). After 3 days of doing this manually I was given the go ahead to use any resources necessary to make it stop and especially since it was IIS6 I had no fucking clue where to start.

So I stuck to what I knew and deployed a $5 vm running an Nginx reverse proxy with heavy caching and rate limiting linked to a custom fail2ban plugin in in front of the insecure server. The attacks died instantly, the server sped up 10x and was never compromised by bots again (presumably since they got back a linux user agent). To this day I marvel at this miracle $5 fix.

I've optimised so many things in my time I can't remember most of them.

Most recently, something had to be the equivalent off `"literal" LIKE column` with a million rows to compare. It would take around a second average each literal to lookup for a service that needs to be high load and low latency. This isn't an easy case to optimise, many people would consider it impossible.

It took my a couple of hours to reverse engineer the data and implement a few hundred line implementation that would look it up in 1ms average with the worst possible case being very rare and not too distant from this.

In another case there was a lookup of arbitrary time spans that most people would not bother to cache because the input parameters are too short lived and variable to make a difference. I replaced the 50000+ line application acting as a middle man between the application and database with 500 lines of code that did the look up faster and was able to implement a reasonable caching strategy. This dropped resource consumption by a minimum of factor of ten at least. Misses were cheaper and it was able to cache most cases. It also involved modifying the client library in C to stop it unnecessarily wrapping primitives in objects to the high level language which was causing it to consume excessive amounts of memory when processing huge data streams.

Another system would download a huge data set for every point of sale constantly, then parse and apply it. It had to reflect changes quickly but would download the whole dataset each time containing hundreds of thousands of rows. I whipped up a system so that a single server (barring redundancy) would download it in a loop, parse it using C which was much faster than the traditional interpreted language, then use a custom data differential format, TCP data streaming protocol, binary serialisation and LZMA compression to pipe it down to points of sale. This protocol also used versioning for catchup and differential combination for additional reduction in size. It went from being 30 seconds to a few minutes behind to using able to keep up to with in a second of changes. It was also using so much bandwidth that it would reach the limit on ADSL connections then get throttled. I looked at the traffic stats after and it dropped from dozens of terabytes a month to around a gigabyte or so a month for several hundred machines. The drop in the graphs you'd think all the machines had been turned off as that's what it looked like. It could now happily run over GPRS or 56K.

I was working on a project with a lot of data and noticed these huge tables and horrible queries. The tables were all the results of queries. Someone wrote terrible SQL then to optimise it ran it in the background with all possible variable values then store the results of joins and aggregates into new tables. On top of those tables they wrote more SQL. I wrote some new queries and query generation that wiped out thousands of lines of code immediately and operated on the original tables taking things down from 30GB and rapidly climbing to a couple GB.

Another time a piece of mathematics had to generate all possible permutations and the existing solution was factorial. I worked out how to optimise it to run n*n which believe it or not made the world of difference. Went from hardly handling anything to handling anything thrown at it. It was nice trying to get people to "freeze the system now".

I build my own frontend systems (admittedly rushed) that do what angular/react/vue aim for but with higher (maximum) performance including an in memory data base to back the UI that had layered event driven indexes and could handle referential integrity (overlay on the database only revealing items with valid integrity) or reordering and reposition events very rapidly using a custom AVL tree. You could layer indexes over it (data inheritance) that could be partial and dynamic.

So many times have I optimised things on automatic just cleaning up code normally. Hundreds, thousands of optimisations. It's what makes my clock tick.

Dogecoin hit USD $0.40 recently, which means it's time for the Crypto Rant.

TL;DR: Dogecoin is shit and is logically guaranteed to eventually fall unless it is fundamentally changed.

===========================

If you know how Crypto works under the hood, you can skip to the next section. If you don't, here's the general xyz-coin formula:

Money is sent via transactions, which are validated by *anybody*.

Since transactions are validated by anybody, the system needs to make sure you're not fucking it up on purpose.

The current idea (that most coins use today) is called proof-of-work. In short, you're given an extremely difficult task, and the general idea is you wouldn't be willing to do that work if you were just going to fuck up the system.

For validating these transactions, you are rewarded twofold:

1) You are given a fixed-size prize of the currency from the system itself. This is how new currency is introduced, or "minted" if you prefer.
2) You are given variable-size and user-determined prize called "transaction fees", but it could be more accurately called a "bribe" since it's sole purpose is to entice miners to add YOUR transaction to their block.

This system of validation and reward is called mining.

===========================

This smaller section compares the design o f BTC to Dogecoin - which will lead to my final argument

In BTC, the time between blocks (chunks of data which record transactions and are added to the chain, hence blockchain) is ten minutes. Every ten minutes, BTC transactions are validated and new Bitcoins are born.

In Dogecoin, the time between blocks is only one minute. In Theory, this means that mining Dogecoin is about ten times easier, because the system expects you to be able to solve the proof of work in an average of one minute.

The huge difference between BTC and Doge is the block reward (Fixed amount; new coins minted). The block reward for BTC is somewhat complicated compared to Doge: It started as 50 BTC per block and every 4 years it is halved ("the great halving"). Right now it's 6.25 BTC per block. Soon, the block reward will be almost nothing until BTC hits it's max of 21 million bitcoins "minted".

Dogecoin reward is 10,000 coins per block. And it will be that way for the end of time - no maximum, no great halving. And remember, for every 1 BTC block mined, 10 Doge blocks are mined.

===========================

Bitcoin and Dogecoin are now the two most popular coins in pop culture. What makes me angry is the widespread misunderstanding of the differences between the two. It is likely that most investors buy Dogecoin thinking they're getting in "early" because it's so cheap. They think it's cheap because it isn't as popular as Bitcoin yet. They're wrong. It's cheap because of what's outlined in section two of this rant.

Dogecoin is actually not very far off Bitcoin. Do the math: there's a bit over 100 billion Dogecoin in circulation (130b). There's about 20 million BTC. Calculate their total CURRENT values:

130b * $0.40 = 52b
20m * $60k = 1.2t

...and Doge is rising much, much faster than BTC because of the aforementioned lack of understanding.

The most common thing I hear about Doge is that "nobody expects it to reach Bitcoin levels" (referring to being worth 60k a fucking coin). They don't realize that if Doge gets to be worth just $10 a coin, it will not just reach Bitcoin levels but overtake Bitcoin in value ($1.3T).

===========================

It's worth highlighting that Dogecoin is literally designed to fail. Since it lacks a cap on new coins being introduced, it's just simple math that no matter how much Doge rises, it will eventually be worthless. And it won't take centuries, remember that 100k new Doge are mined EVERY TEN MINUTES. 1,440 minutes in a day * 10K per minute is 14.4 million new coins per day. That's damn near every Bitcoin to ever exist mined every day in Dogecoin

This happened with one of our senior profs during the first year of my college. I wouldn't call him a dev if my life depended on calling him a dev but regardless, I narrate the story here.

We were "taught" C++ by some really dumb professors during our first year of college and it was mandatory that everyone cleared the subject regardless of what field of engineering the students chose. Having already done 2 years of C++, it was quite a breeze for me. But during the final lab exam, one of my friends requested my help in solving the quite tough question (for those beginners). Thinking the exam and teaching was unfair, I stupidly wrote the answer on a piece of paper and passed it to him. One of our teachers, who had seen him ask me, was lying low waiting to catch me in the act and she swooped in and busted our asses kicking us out of the exam hall and sending us to the HoDs office like some prize from her war against academic corruption.
In the end, I failed the exam for cheating and had to redo (not only the exam but the entire lab course).

When I returned to college during the summer vacations to redo the course, I first met the antagonist of our story. Having a huge head that looked like a deformed watermelon and an ego the size of a building, he assaulted us first with a verbal diarrhoea of his achievements as a CS professor. I quickly realised that I was in a class of people who had failed to grasp how to make a program that printed "Hello World". To make things shorter, every question the prof gave us, I managed to solve in a mere matter of minutes, several better than his own solutions. Not having expected a student who knew his shit, he was determined to play me down. He hurled tougher question at me and I knocked them over his enormous head piercing his ego. He asked me such questions as how to reverse 1000 and get 0001 and wasn't satisfied with the several ways I gave because none of it were what he had in mind (which turned out to be storing them in a fucking array and printing them in reverse. That's printing not reversing you dung beetle). I kept my calm throughout but on the day of the final exam, he set quite a tough paper for a class of people who had already failed once. To his utter shock and dismay, I aced that too and I produced flawless code. This man who has an MTech from one of the most reputed colleges of my country then proceeded to tell me that he had to cut my marks because I had used more than one function when the question had asked for one function ( it never said only one). I lost my shit and pointed out that since I was the programmer, it was my wish how I coded. I also explained to him how repeating code is a bad practice and one should use functions to reduce redundancy and keep the code clean. Nevertheless, he lost his shit and he threatened me with consequences as apparently "I didn't know who I was messing with". I handed over the paper and stormed out of the class (though he called me back and tried to argue more with me. I apologized for losing my shit and left when he was done talking). I ended up getting a 'C'. Totally worth it.

Approximately 15 years ago, at school, I had one friend that learned to code in Delphi. One day he came to me and said:
Dude! I made a program that creates a 2GB file!!! (15 years ago 2GB were a lot of memory)
- What is in this file? - I asked.
- Nothing! It's just 2GB!!!
- It's fucking AWESOME!!!

What the actual fuck. I just found out that on one of the SSD's I bought, the optimal partition start / finish sizes which apparently on that unit only occur every 65 THOUSAND 4kB sectors (which translates to about a quarter GB) means that I have to throw away half a GB worth of space on that disk in order to align it. Very optimized indeed, dear SSD manufacturer! Huge alignment numbers for just that much extra wastage in the name of optimization. Something like 4x sector size on 512 byte sectors or 1x sector size on 4k sectors.. ain't nobody gonna need that. Let's make it a quarter GB.

And that's what they call engineering?

Need some opinions. Joined a new company recently (yippee!!!). Just getting to grips with everything at the minute. I'm working on mobile and I will be setting up a new team to take over a project from a remote team. Looking at their iOS and Android code and they are using RxSwift and RxJava in them.

Don't know a whole lot about the Android space yet, but on iOS I did look into Reactive Cocoa at one point, and really didn't like it. Does anyone here use Rx, or have an opinion about them, good or bad? I can learn them myself, i'm not looking for help with that, i'm more interested in opinions on the tools themselves.

My initial view (with a lack of experience in the area):

- I'm not a huge fan of frameworks like this that attempt to change the entire flow or structure of a language / platform. I like using third party libraries, but to me, its excessive to include something like this rather than just learning the in's / out's of the platform. I think the reactive approach has its use cases and i'm not knocking the it all together. I just feel like this is a little bit of forcing a square peg into a round hole. Swift wasn't designed to work like that and a big layer will need to be added in, in order to change it. I would want to see tremendous gains in order to justify it, and frankly I don't see it compared to other approaches.

- I do like the MVVM approach included with it, but i've easily managed to do similar with a handful of protocols that didn't require a new architecture and approach.

- Not sure if this is an RxSwift thing, or just how its implemented here. But all ViewControllers need to be created by using a coordinator first. This really bugs me because it means changing everything again. When I first opened this app, login was being skipped, trying to add it back in by selecting the default storyboard gave me "unwrapping a nil optional" errors, which took a little while to figure out what was going on. This, to me, again is changing too much in the platform that even the basic launching of a screen now needs to be changed. It will be confusing while trying to build a new team who may or may not know the tech.

- I'm concerned about hiring new staff and having to make sure that they know this, can learn it or are even happy to do so.

- I'm concerned about having a decrease in the community size to debug issues. Had horrible experiences with this in the past with hybrid tech.

- I'm concerned with bugs being introduced or patterns being changed in the tool itself. Because it changes and touches everything, it will be a nightmare to rip it out or use something else and we'll be stuck with the issue. This seems to have happened with ReactiveCocoa where they made a change to their approach that seems to have caused a divide in the community, with people splitting off into other tech.

- In this app we have base Swift, with RxSwift and RxCocoa on top, with AlamoFire on top of that, with Moya on that and RxMoya on top again. This to me is too much when only looking at basic screens and networking. I would be concerned that moving to something more complex that we might end up with a tonne of dependencies.

- There seems to be issues with the server (nothing to do with RxSwift) but the errors seem to be getting caught by RxSwift and turned into very vague and difficult to debug console logs. "RxSwift.RxError error 4" is not great. Now again this could be a "way its being used" issue as oppose to an issue with RxSwift itself. But again were back to a big middle layer sitting between me and what I want to access. I've already had issues with login seeming to have 2 states, success or wrong password, meaning its not telling the user whats actually wrong. Now i'm not sure if this is bad dev or bad tools, but I get a sense RxSwift is contributing to it in some fashion, at least in this specific use of it.

I'll leave it there for now, any opinions or advice would be appreciated.

We were a small startup with only 5-6 developers. I had to design the UI and develop most of the Android frontend, It was quite an easy and fun job for me because I don't get to see people rant about the design that needed to be implemented so, usually I design something that can be easily implemented.
We got 2 projects with a tight deadline and I took care of both project's design part and after completing the design I took the entire frontend of one project and rest of em started working with the other one. Usually we were a strong team and was able to deliver things real quick because we were expert in our intrested fields, I had a fast start in my project where the other project lagged a lot because of the desifn which was hard to implement by them, and the frontend was bo where near to get completed by the deadline and I couldn't help them out because it was all messed up shit handling both projects together.

Finally we were in a situation where none of our project are ready and the deadline was about to hit within a week, so we halted the other project and asked them to join me to complete the project am Working on, I had built most of the Android part and these fellows had a hard time figuring out stuff I made up (yeah, documentation was shit while you go agile), and finally things messed up and I had to work 2 continuous day and night without any sleep just to get the app ready 10 minutes before the official proto presentation.

The best part is I couldn't even get up from my chair and had a headache, fainted instantly when I took a few steps, but the product launch went good.

We fucked uo the code and both the projects just because we weren't available for each other considering the size of the team. Anyway we completed the project but It was a huge failure for us being first time to manage a startup.

Learned a lot of lessons,
Always make a team with people who are good at each of the aspect of development and never divide it to get shit done faster.

This is one from when I was in school, so I wasn't a dev but it made me feel like a CS student badass.

A class mate and I were having a discussion about his study habits. Basically he was freaking about the mount of studying he was going to have to do for this class:

Me: dude, you need to relax. You'll do fine.
Classmate: no, have you seen the amount of work that is on the syllabus? The size of the book?
Me: wait you bought the book? Also we took this same professor for several classes. His syllabuses are always huge. What did you get in the prereq to this class?
CM: an A.
Me: there you go.
CM: but I had to study all the time. I had no free time.
Me: really? I had an insane amount of free time.
CM: what did you get?
Me: B+.
CM: See but I did better than you.
Me: yeah . . . but I had fun last year.
Professor: you know, it's hard to tell who is the better student. The one that had no fun, but got an A. Or the one that had a lot of fun and got a B.
Other Classmates: probably the guy that got the B.

Hurray for peer and professor validated laziness.

Affinity Designer export to SVG, normally an easy task for a vector programme.
Furthermore it is only a little picture, a clear eight filled with a single colour.
Result: SVG with an unbelievable file size of 98.7 kB. Holy shit!
Looked at it: The export made a huge long high scaled path... oh man...
Little hand made recoding, made four circles. Done. New size: 0.8 kB.
That's better.

iiiii fffffuckingg hate articles that just explain something

put a piece of code

that piece of code uses X amount of classes/models

they never mention what structure are those models/classes made of

what is inside them

i cant continue following the article because i dont know what is inside them

they just put it in ur face and say Fuck you

no

Fuck YOU

<font size="1000000px;">FUCK</font>

br b wait for me ok

i feel better now

fck

i remembered that goddamn girl again

man i feel so heart broken

srsly

i have sunk into the deepest depths of endless depression I think

it doesnt feel nice

it feels very lonely and depressing down here

but i thimk tjat is be because i care too much

some people say i overthink

I dont overthink

i am like the stealth people
the shadow people

i stay quiet and observe

everything

i always know what is happening but i rarely speak about it

and people dont realize

so they think they can fool me

no

everything has its limits

so much lies that im sick of it

i always tell it how it is

i always reward those who help me

i always help those who help me

i never forget those people

zzzZZ

why is it that people who dont give a single fucking Fffffficxkkckck about me

are the ssame people i almost care the MOST?

i cross hundreds and thousands of miles to visit a person, invest hours of my time to do that

i do that....

and they wouldnt even step 1 foot in front to see me....

what kind of life is this

vv

feel like cryin rn

.

zzzzz

.

i dont understand what one must do

what is the point

all i want is to be happy

that is it

but being happy is.... i wanted to say the hardest part of life but now my voice told me being happy is a state of mind

myself answered me that being happy ? is a state of mind?

so that means if i want to be happy even if everything around me is falling apart

in my mind i can create a psychological world that would make me.... happy ....?

or what

i dont understand what did myself tell me

why do i care so much if im lonely

u know my friend from college we go to same computer science college

hes a very smart man but a fake FUCKING friend, plastic as fuck

he reads philosophy booms and told me

"when a man is lonely for long enough, he will slowly start to fall apart"

that is me...... that is ...truth......

he quoted a philosopher from some book

zzzz

he also said a quote he read about the meaning of life

"this life is endless pain and the only purpose of life is to reduce this pain as much as possible so we can be happy"

what the fck that is incredibly depressing

what the fuck im actually crying rn

i feel stabbed in the back and left behind and cheated on, all of those happened and some of them are happening right now

dont know what to think about the reasons

all of this causes me such huge anger and depression and that is whT keeps me going

going by working harder than i am supposed to

without all this hurt there would be no glory

all this effort..... it better pay off at the end...... please God..... i beg you....

i have completed 50% of my life purpose, let me do the rest so i can die in peace...

When I hit the endpoint from Postman it works. When I hit the endpoint from my application that pushes data to the endpoint it doesn't work, returning a 404 status code. I KNOW the endpoint is there and operational and that both Postman and my application have the same endpoint configured, letter for letter.

So lost. So confused. What the hell is going on.

I decide to install Fiddler to monitor the traffic to see if I can see anything helpful.

I initiate the request again from the application and immediately see that the request size is huge. BAM. It immediately hits me, the payload to the endpoint is too big and the server is "rejecting" it with a 404. I post a smaller request with the application and it works fine.

Yay, saved by Fiddler.

Why does the endpoint default to 404 in such scenarios. The definition of 404: "the client was able to communicate with a given server, but the server could not find what was requested"

In my case, the 404 returned was a red herring. I understand that the substatus code gives more information on why the 404 was returned, in my case the request size being too big, but 404 in general feels like the wrong status code to return because the endpoint IS there. It made me troubleshoot the wrong thing.

Thanks, IIS.

My teacher wants me to run HelloWorld Application made in Android Studio ._.
First of all, its f**king huge in size
Second, we thought that only Chrome was notorious for being ram hungry.

ERRRR MAAAAH GAAAWD CRINGE!!

I had a relative that used to come to our house to study because her home was kinda far and also because we had a computer .
She was studying computer science at the time and I was only 13-14 years old. One day she came with 3 CDs of red hat. I asked her about it and she told me it's something like windows. My reaction was wow it must be something huge because I knew at the windows XP was only the size of one CD .
My relation with computers was only to play games and some music that's why I couldn't hold myself not to install it. I fucked my computer endless times, It was like playing puzzles let's try this option and then switch to another... It took me like 4 days to install and I was really impressed with it you know seeing the terminal and stuff. Weeks later I switched back to Windows because I couldn't install my games and play mp3 files (require to install some libraries and I had no internet).
Fast forward 8 years later and I was studying linux system for CS degree and guess what? I was the major in class because I knew about many stuff like partition systems (ext2, swap..) and how to install linux on a computer...
This was my feeling 😎 at class.

Considering paying my boss to drop a client, because a function only they need can't really be implemented more brilliantly than a huge if/else, doubling the size of the source code.

Why does my phone (most phones) record video that are like 100s of MB for just a few minutes? Where as I can download the same video and similar quality but much smaller from Youtube after I upload it?

Originally I used Youtube to stabilize videos but seems they removed that... so now I just want the videos with reasonable size.

Not sure if this was from OpenCamera (I think I have it forcing 4K UHD, prolly don't need); I don't know what the setting is in Camera, can't change it.

But smartphone videos are always huge...

Spot the difference in the package size.
Makes a huge impact when deploying it on a motherboard. 😅

The only valuable life lesson I have ever gotten and I could give is 'fake it till you make it'. Doesn't it begin by playing an adult as a child? It's the same throughout whole life: Whenever they think you are good at something they will give you chances to actually do it and practice it. Regardless of we are speaking about sports at school (where they have to think you are good enough to give you the ball from time to time so you can even learn the game) or getting laid, or whatever job you are going to have: you have to fake some competence at first to get a chance to even try it. The key to success is to have a good feeling of how much fake is appropriate in which situation.
A lot of ppl in their early twenties and below think ppl are getting something they call mature or professional (when speaking about work) at one point in life. When they grow older and don't feel mature or prefessional at all but has to act as if they where, they feel like an imposter. But lemme tell you, now that I have to do with literal professors and other successful ppl: behind the scenes it's all the same fights and fears, the same anger and the craving for approval and friends hip, the same teaming IP and intrigues between them like between you and your mates back then on the playground.
At the latest when it comes to parenthood, you realize it. you got thrown into this huge quest with a shitload of responsibility and unnumbered side quests without any chance to be prepared and the same happened to your parents and theirs and to all the other parents you now are used to meet, back at the playground. All they can do is trying there best and keep a professional face. although some will tell you they are better at parenting bc they have have always the right size of diapers with them they are amateurs (or imposters if you want it) like you. Like your parents when you looked up to them pretending to know what they do. In fact, nobody knows. Maturity is a lie. Professionalism a fake. We stay always the same children playing in the sand we used to be. We only got better in playing adults.

So what now is imposter syndrome? Just another way modern society invented to hate yourself for being human.

That's it. Thats all I can tell about life after i survived the first half. I gave it all to you devrant, thank you for your attention, now get of my lawn.

I watched a few reviews for the new nvidia RTX 4070 Ti graphics card. One question on my mind is: why is it so huge?

⏺️4090 is huge -> ok I get it, 450W power is a lot of W
⏺️4080 is huge -> ok I guess, 320 W of power is a still a lot of W; although it should be considerably smaller than 4090 (but it is not? why)
⏺️4070 Ti is huge -> 3 slots size for this graphics card? What the actual hell? This card is rated just 285 W. It makes no sense

I do not get it. The only explanation I can find is that the manufacturer got so lazy they cannot be bothered to design 3 different cooling systems, so they reuse the same cooling system on all graphics cards. RIP

I felt pretty smart about replacing that huge php database import script with a bash script loading the XML dump via MySQL's LOAD XML INFILE feature directly.

Why then does the php script only take 35 minutes for all the tables to import, whereas my script takes almost 2 fucking hours for that one table? We are talking an import of the ridiculous size of 70 MB. I don't get it. It's supposed to be fast.

Do you ever feel your job is too demanding compared to other software engineering jobs?

I've worked in two companies for now.
First company, Kotlin microservices and we had QAs, didn't have to write a lot of tech specs and no post mortem or on call at all (not yet atleast), it was just talk to PO, he tells the business requirement, we work together to make tickets, no legacy code so was easy to know what to do for tech, no monolith to handle or anything, much easier, just code and meetings.

Current job is meetings with PO telling you what he wants, have to write a full on tech spec and also know business requirements and product knowledge as the current PO doesn't know anything about how the products work, writing huge tech specs, communicating on requests sent my clients on slack, pretty much always firefighting, the system is so fragile and legacy, coding is actually less its mostly spending hours finding out how this shittt legacy flows work (no docs) , PO pretty much does fuck all, just wants meetings and wants us to do very very stupid tedious low impacts projects. This bundled with oncall and onpoint and the absolute sheer amount of incidents our team is involved in (on average we have 4 a week LOL, varying size but they're all very annoying) and the overtime oncall benefit is so bad too, if you do get paged out of hours, you just get that hour back during work hours. In other companies like friends, you get paid for the whole time you're oncall, whether you get paged or not. I can't go out anywhere on weekends or anywhere at all during on call in case I get paged, which happens a lot. Its a cluster of a mess. This bundled with manager stoll not wanting to promote me to IC3 despite all I've done so far.

My question is, is this more normal than I think it is? Is this just how crap our career can be? Mind you I'm in the UK so not getting those mind boggling US wages sadly either. Have US colleagues in same team doing same job but obviously getting more

My vague naive extreme understanding of interview questions are on a spectrum from situation a to situation b.

But what should the industry be doing? Is the industry just going wrong blindly copying big N companies hiring process without the same rationale? (e.g. they need computer scientists able to deal with problems specific to them at their size and that often means creating new tech, unreal problem solving abilities and cuh-rayzee knowledge)

a) stupid fucking theoretical shit that some people argue you won't ever need to be doing in practice for most companies, while giving you no ability to google, leetcode hard problems kind of stuff

b) practical work similar to what you'd be doing on the job, small bugs, tasks, pair programming on site with your potential future coworkers

Lots of people hate option a because it's puzzle/problem solving that isn't always closely related to what's on the job. Whiteboarding is arguably very much a separate skill. (Arguably unless it's like a big N company where you want computer scientists to deal with specific problems that aren't seen elsewhere, and you're making new tech to deal with your specific problems.)

We could go to the extreme of Option b, but it tends to trigger people into shitfits of "NO, HOW DARE YOU MAKE ME DO REAL WORK, BUT NOT PAY ME FOR IT AT THE INTERVIEW STAGE"

That's before we get into how to execute option b whether or not it's being given as a take home assignment (which is a huge pain in the ass and time sink, among other issues) vs a few hours at the potential workplace working with some of the future potential coworkers and soaking in the work environment (you have to figure out how to take the time off then)

Is it really just poor execution overall for the wrong use cases for the majority of the industry? What should the industry be doing in which cases.

Then this is all before HR screening with shit like where they might ask for more years of swift experience than its existed.

suggestion for devRant

I'm posting them here so if others want they can flame me as they see fit.

- Please add the ability to customize which notifications to get and which rants to watch.

- Please move around options in profile and settings and for the love of God move the delete profile button. It's just behind the settings button so if you press settings and click again there's a chance you have clicked the delete button.

- Some of the app is using JS for navigation and other parts don't. Pagination can be done with JS. Seeing notifications too.

- I get that the app is designed this way to be displayed on mobile but for someone like me who uses the web app the small editor and it's huge font size and the big plus button are really annoying.

I love this place. I hope it gets better.

So I have a client project that needs to be delivered in 3 months. The project size is significantly huge, so a lot of devs will work with me. Our seniors have its architecture defined in micro services but we have no clue how they work. I would really appreciate some community inputs on how can we scalable-ly use micro services.

Just like last week's rant with developers, I've never really had any huge arguments with designers. Most of them been pretty cool, and if anything, I learned quite a few things from them that you would never learn as a developer.

Although minor, at most I had an issue with a designer was how they were adamant about not reducing the file size of images. They were arguing that it would make the site look terrible.

I hate sketch, not because it's an Apple only product, but because it's horrible to navigate. I couldn't imagine using it with out a side scrolling mouse, and none of the "normal" keyboard shortcuts work. The plugins are horrible and almost always cause more problems then they fix.

But the biggest issue, and this may be the designers that I work with, but I'm not sure. The files are huge. The smallest file I have worked with was 80mb, yesterday I received a file that was almost 1gb! It had every page, with all the text, in every size, it was insane, I turned the job down based on that alone. It had a decent budget, but the client expected way too much. And the designs for each page were different, which as we know can cause issues for the overall UX.

The screenshot is from my PC as I don't have my OS X VM fired up right now, but that's a real file, just shown with XD.

I need urgent answer as quora is being weird like always. Ok here we go. I have a project idea but its really huge in size. Lots of features.

My question is. I recently learned Angular 2 but I know jquery well. Which one should I choose for the frontend? Please give your opinions. I need your expert advice.

It's these individually tiny annoyances in products and software that together form a huge annoyance.

For example, it's 2022 and Chromium-based web browsers still interrupt an upload when hitting CTRL+S. This is why competition is important. If there was no Firefox, the only major web browsers would, without exception, have this annoyance, since they're all based on Chrmoium.

I remember Chromium for mobile formerly locking scrolling and zooming of the currently viewed page while the next page was loading. Thankfully, this annoyance was removed.

In 2016, the Samsung camera software was updated to show a "camera has been opened via quick launch" pop-up window when both front and rear sensors of the smartphone were covered while the camera was launched by pressing the home button twice, on the camera software Samsung bundled with their custom version of Android 6. What's more, if that pointless pop-up was closed by tapping the background instead of the tiny "OK" button or not responded to within five seconds, the camera software would exit itself. Needless to say, this defeats the purpose of a quick launch. It denies quick-launching while the phone is in the pocket, and the time necessary to get the phone out could cause moments to be missed.

Another bad camera behaviour Samsung introduced with the camera software bundled with their customized Android 6 was that if it was launched again shortly after exiting or switching to stand-by mode, it would also exit itself again within a few seconds. It could be that the camera app was initially designed around Android 5.0 in 2015 and then not properly adapted to Android 6.0, and some process management behaviour of Android 6.0 causes this behaviour. But whatever causes it, it is annoying and results in moments to not be captured.

Another such annoyance is that some home screen software for smartphones only allows access to its settings by holding a blank spot not occupied by a shortcut. However, if all home screen pages are full, one either needs to create a new page if allowed by the app, or temporarily remove a shortcut to be able to access the settings.

More examples are: Forced smartphone restart when replacing the SIM card, the minimum window size being far too large in some smartphones with multi-windowing functionality, accidental triggering of burst shot mode that can't be deactivated in the camera software, only showing the estimated number of remaining photos if less than 300 and thus a late warning, transition animations that are too slow, screenshots only being captured when holding a button combination for a second rather than immediately, the terminal emulator being inaccessible for the first three minutes after the smartphone has booted, and the sound from an online advertisement video causing pain from being much louder than the playing video.

Any of these annoyances might appear minor individually, but together, they form a major burden on everyday use. Therefore, developers should eliminate annoyances, no matter how minor they might seem.

The same also applies for missing features. The individual removal of a feature might not seem like a big of a deal, but removing dozens of small features accumulates to a significant lack of functionality, undermining the sense of being able to get work done with that product or software when that feature is unexpectedly needed. Examples for a products that pruned lots of functionality from its predecessor is the Samsung Galaxy S6, and newer laptops featuring very few USB ports. Web browsers have removed lots of features as well. Some features can be retrofitted with extensions, but they rely on a third-party developer maintaining compatibility. If many minor-seeming features are removed, users will repeatedly hit "sorry, this product/software can not do that anymore" moments.
