Accountant: Can we just get one big Excel file with all the transactions instead of separate reports that are filled out specifically for each dorm?
Me: Hell yes you can.3 -
I haven't ranted for today, but I figured that I'd post a summary.
A public diary of sorts.. devRant is amazing, it even allows me to post the stuff that I'd otherwise put on a piece of paper and probably discard over time. And with keyboard support at that <3
Today has been a productive day for me. Laptop got restored with a "pacman -Syu" over a Bluetooth mobile data tethering from my phone, said phone got upgraded to an unofficial Android 9 (Pie) thanks to a comment from @undef, etc.
I've also made myself a reliable USB extension cord to be able to extend the 20-30cm USB-A male to USB-C male cord that Huawei delivered with my Nexus 6P. The USB-C to USB-C cord that allows for fast charging is unreliable.. ordered some USB-C plugs for that, in order to make some high power wire with that when they arrive.
So that plug I've made.. USB-A male to USB-A female, in which my short USB-C to USB-A wire can plug in. It's a 1M wire, with 18AWG wire for its power lines and 28AWG wires for its data lines. The 18AWG power lines can carry up to 10A of current, while the 28AWG lines can carry up to 1A. All wires were made into 1M pieces. These resulted in a very low impedance path for all of them, my multimeter measured no more than 200 milliohms across them, though I'll have to verify and finetune that on my oscilloscope with 4-wire measurement.
So the wire was good. Easy too, I just had to look up the pinout and replicate that on the male part.
That's where the rant part comes in.. in fact I've got quite uncomfortable with sentences that don't include at least one swear word at this point. All hail to devRant for allowing me to put them out there without guilt.. it changed my very mind <3
Microshaft WanBLowS.
I've tried to plug my DIY extension cord into it, and plugged my phone and some USB stick into it of which I've completely forgot the filesystem. Windows certainly doesn't support it.. turns out that it was LUKS. More about that later.
Windows returned that it didn't support either of them, due to "malfunctioning at the USB device". So I went ahead and plugged in my phone directly.. works without a problem. Then I went ahead and troubleshooted the wire I've just made with a multimeter, to check for shorts.. none at all.
At that point I suspected that WanBLowS was the issue, so I booted up my (at the time) problematic Arch laptop and did the exact same thing there, testing that USB stick and my phone there by plugging it through the extension wire. Shit just worked like that. The USB stick was a LUKS medium and apparently a clone of my SanDisk rootfs that I'm storing my Arch Linux on my laptop at at the time.. an unfinished migration project (SanDisk is unstable, my other DM sticks are quite stable). The USB stick consumed about 20mA so no big deal for any USB controller. The phone consumed about 500mA (which is standard USB 2.0 so no surprise) and worked fine as well.. although the HP laptop dropped the voltage to ~4.8V like that, unlike 5.1V which is nominal for USB. Still worked without a problem.
So clearly Windows is the problem here, and this provides me one more reason to hate that piece of shit OS. Windows lovers may say that it's an issue with my particular hardware, which maybe it is. I've done the Windows plugging solely through a USB 3.0 hub, which was plugged into a USB 3.0 port on the host. Now USB 3.0 is supposed to be able to carry up to 1A rather than 500mA, so I expect all the components in there to be beefier. I've also tested the hub as part of a review, and it can carry about 1A no problem, although it seems like its supply lines aren't shorted to VCC on the host, like a sensible hub would. Instead I suspect that it's going through the hub's controller.
Regardless, this is clearly a bad design. One of the USB data lines is biased to ~3.3V if memory serves me right, while the other is biased to 300mV. The latter could impose a problem.. but again, the current path was of a very low impedance of 200milliohms at most. Meanwhile the direct connection that omits the ~200ohm extension wire worked just fine. Even 300mV wouldn't degrade significantly over such a resistance. So this is most likely a Windows problem.
That aside, the extension cord works fine in Linux. So I've used that as a charging connection while upgrading my Arch laptop (which as you may know has internet issues at the time) over Bluetooth, through a shared BNEP connection (Bluetooth tethering) from my phone. Mobile data since I didn't set up my WiFi in this new Pie ROM yet. Worked fine, fixed my WiFi. Currently it's back in my network as my fully-fledged development host. So that way I'll be able to work again on @Floydian's LinkHub repository. My laptop's the only one who currently holds the private key for signing commits for git$(rm -rf ~/*)@nixmagic.com, hence why my development has been impeded. My tablet doesn't have them. Guess I'll commit somewhere tomorrow.

Conversation with coworker at a staff function...
girl: ...we can't wait to see what you can do!
Me: Great! I can't wait to get stuck in, but you know, those exports you wanted from it, that doesn't have to wait. If you need that straight away, come to my desk and I'll make some queries for you and pull out the data you want...
Girl: o_0
Girl: ... Omg, you can do that?! You're awesome!!
Me later: o_0 - the Dev before me could never at least do that?!6 -
Maybe not a new rant but: When someone asks you for a feature and always says "its easy and simple" ... Yeah right... 😡2

I've been thinking about how to answer this for a while, but I'll approach it from a different angle. The time I (nearly) lost faith in my dev future wasn't because of a technology, bad programming language or an external influence. It was *me*.
The first job I had after the PhD, I was (in the first couple of weeks) tasked with updating various packages on a live Redhat server. "No problem", I thought, "I've done this before many a time on Debian, easy as pie!"
Long story short, I ended up practically bricking the server because I mistyped and uninstalled something I shouldn't have, didn't understand a piece of configuration, then tried to bodge it back and cocked things up further. Couldn't even log in via SSH, the hosting company had to be called, a serial connection set up, etc.
To say I was mortified, embarrassed and had my pride dented would be a massive understatement. I seriously thought I'd get fired on the spot, and that I should perhaps change careers to something where I couldn't cock things up as much.
...but you can't think like that, otherwise the world leaves you behind. So I picked myself up, apologised profusely, took some relevant training, double checked everything I was doing on that server in future and got back to work. After a few months of "proving myself", it was then seen as nothing more than a rather amusing story, and I became a senior dev there a couple of years later.1 -
Recently I flashed Android 9 (Pie) on my Nexus, but to this day I still haven't logged into Google from it. One reason is because I don't know my password and I didn't git clone my password store yet (where it's contained). Another reason is because I want to reclaim my privacy and not be a data battery for a Matrix of convenience that feeds itself with my personal information. Eh, it sorta works out I guess. Yalp is an amazing alternative to the Play Store, and even offers its own shadow accounts to use along with Google Play.
One problem though, while I've noticed that I could log in with my own account to get all my premium apps (couple hundred euros worth, so not easy to just discard) it apparently violates Google Play's ToS to do so from a third-party app. So I'm a bit hesitant to do that. Do you know of any viable alternative way to preserve my privacy yet install, keep and have validated those premium apps? I could download them from e.g. BlueStacks and export the apk's, but that'd be tedious and wouldn't be able to get those apps validated on my phone unless I log into Google there as well (which kinda defeats the purpose). Any suggestions?23 -
Someone posted this to our shared channel. I'm so tired of people thinking that developers "just need to push a few buttons".
Am I crazy for believing that all I can accomplish in 4 hours is read their documentation (or there lack of), and maybe write few tests for the slew of things they'll be asking for??? And maybe, just maybe, get my local environment running.
Why does everyone think that developers know the location of the "magic button"???3 -
These ignorant comments about arch are starting to get on my nerves.
You ranted or asked help about something exclusive to windows and someone pointed out they don't have that problem in arch and now you're annoyed?
Well maybe it's for good.
Next comes a very rough analogy, but imagine if someone posts "hey guys, I did a kg of coke and feeling bad, how do I detox?"
It takes one honest asshole to be like "well what if you didn't do coke?".
Replace the coke with windows.
Windows is a (mostly) closed source operating system owned by a for profit company with a very shady legal and ethical history.
What on earth could possibly go wrong?
Oh you get bsod's?
The system takes hours to update whenever the hell it wants, forces reboot and you can't stop it?
oh you got hacked because it has thousands of vulnerabilities?
wannacry on outdated windows versions paralyzed the uk health system?
oh no one can truly scrutinize it because it's closed source?
yet you wonder why people are assholes when you mention it? This thing is fucking cancer, it's hundreds of steps backwards in terms of human progress.
and one of the causes for its widespread usage are the savage marketing tactics they practiced early on. just google that shit up.
but no, linux users are assholes out to get you.
and how do people react to these honest comments? "let's make a meme out of it. let's deligitimize linux, linux users and devs are a bunch of neckbeards, end of story, watch this video of rms eating skin off his foot on a live conference"
short minded idiots.
I'm not gonna deny the challenges or limitations linux represents for the end user.
It does take time to learn how to use it properly.
Nvidia sometimes works like shit.
Tweaking is almost universally required.
A huge amount of games, or Adobe/Office/X products are not compatible.
The docs can be very obscure sometimes (I for one hate a couple of manpages)
But you get a system that:
* Boots way faster
* Is way more stable
* Is way way way more secure.
* Is accountable, as in, no chance to being forced to get exploited by some evil marketing shit.
In other words, you're fucking free.
You can even create your own version of the system, with total control of it, even profit with it.
I'm not sure the average end user cares about this, but this is a developer forum, so I think in all honesty every developer owes open source OS' (linux, freebsd, etc) major respect for being free and not being corporate horseshit.
Doctors have a hippocratic oath? Well maybe devs should have some form of oath too, some sworn commitment that they will try to improve society.
I do have some sympathy for the people that are forced to use windows, even though they know ideally isn't the ideal moral choice.
As in, their job forces it, or they don't have time or energy to learn an alternative.
At the very least, if you don't know what you're talking about, just stfu and read.
But I don't have one bit of sympathy for the rest.
I didn't even talk about arch itself.
Holy fucking shit, these people that think arch is too complicated.
What in the actual fuck.
I know what the problem is, the arch install instructions aren't copy paste commands.
Or they medium tutorial they found is outdated.
So yeah, the majority of the dev community is either too dumb or has very strong ADD to CAREFULLY and PATIENTLY read through the instructions.
I'll be honest, I wouldn't expect a freshman to follow the arch install guide and not get confused several times.
But this is an intermediate level (not megaexpert like some retards out there imply).
Yet arch is just too much. That's like saying "omg building a small airplane is sooooo complicated". Yeah well it's a fucking aerial vehicle. It's going to be a bit tough. But it's nowhere near as difficult as building a 747.
So because some devs are too dumb and talk shit, they just set the bar too low.
Or "if you try to learn how to build a plane you'll grow an aviator neckbeard". I'll grow a fucking beard if I want too.
I'm so thankful for arch because it has a great compromise between control and ease of install and use.
When I have a fresh install I only get *just* what I fucking need, no extra bullshit, no extra programs I know nothing about or need running on boot time, and that's how I boot way faster that ubuntu (which is way faster than windows already).
Configuring nvidia optimus was a major pain in the ass? Sure was, but I got it work the way I wanted to after some time.
Upgrading is also easy as pie, so really scratching my brain here trying to understand the real difficult of using arch.22 -
YGGG IM SO CLOSE I CAN ALMOST TASTE IT.
Register allocation pretty much done: you can still juggle registers manually if you want, but you don't have to -- declaring a variable and using it as operand instead of a register is implicitly telling the compiler to handle it for you.
Whats more, spilling to stack is done automatically, keeping track of whether a value is or isnt required so its only done when absolutely necessary. And variables are handled differently depending on wheter they are input, output, or both, so we can eliminate making redundant copies in some cases.
Its a thing of beauty, defenestrating the difficult aspects of assembly, while still writting pure assembly... well, for the most part. There's some C-like sugar that's just too convenient for me not to include.
(x,y)=*F arg0,argN. This piece of shit is the distillation of my very profound meditations on fuckerous thoughtlessness, so let me break it down:
- (x,y)=; fuck you in the ass I can return as many values as I want. You dont need the parens if theres only a single return.
- *F args; some may have thought I was dereferencing a pointer but Im calling F and passing it arguments; the asterisk indicates I want to jump to a symbol rather than read its address or the value stored at it.
To the virtual machine, this is three instructions:
- bind x,y; overwrite these values with Fs output.
- pass arg0,argN; setup the damn parameters.
- call F; you know this one, so perform the deed.
Everything else is generated; these are macro-instructions with some logic attached to them, and theres a step in the compilation dedicated to walking the stupid program for the seventh fucking time that handles the expansion and optimization.
So whats left? Ah shit, classes. Disinfect and open wide mother fucker we're doing OOP without a condom.
Now, obviously, we have to sanitize a lot of what OOP stands for. In general, you can consider every textbook shit, so much so that wiping your ass with their pages would defeat the point of wiping your ass.
Lets say, for simplicity, that every program is a data transform (see: computation) broken down into a multitude of classes that represent the layout and quantity of memory required at different steps, plus the operations performed on said memory.
That is most if not all of the paradigm's merit right there. Everything else that I thought to have found use for was in the end nothing but deranged ways of deriving one thing from another. Telling you I want the size of this worth of space is such an act, and is indeed useful; telling you I want to utilize this as base for that when this itself cannot be directly used is theoretically a poorly worded and overly verbose bitch slap.
Plainly, fucktoys and abstract classes are a mistake, autocorrect these fucking misspelled testicle sax.
None of the remaining deeper lore, or rather sleazy fanfiction, that forms the larger cannon of object oriented as taught by my colleagues makes sufficient sense at this level for me to even consider dumping a steaming fat shit down it's execrable throat, and so I will spare you bearing witness to the inevitable forced coprophagia.
This is what we're left with: structures and procedures. Easy as gobblin pie.
Any F taking pointer-to-struc as it's first argument that is declared within the same namespace can be fetched by an instance of the structure in question. The sugar: x ->* F arg0,argN
Where ->* stands for failed abortion. No, the arrow by itself means fetch me a symbol; the asterisk wants to jump there. So fetch and do. We make it work for all symbols just to be dicks about it.
Anyway, invoking anything like this passes the caller to the callee. If you use the name of the struc rather than a pointer, you get it as a string. Because fuck you, I like Perl.
What else is there to discuss? My mind seems blank, but it is truly blank.
Allocating multitudes of structures, with same or different types, should be done in one go whenever possible. I know I want to do this, and I know whichever way we settle for has to be intuitive, else this entire project has failed.
So my version of new always takes an argument, dont you just love slurping diarrhea. If zero it means call malloc for this one, else it's an address where this instance is to be stored.
What's the big idea? Only the topmost instance in any given hierarchy will trigger an allocation. My compiler could easily perform this analysis because I am unemployed.
So where do you want it on the stack on the heap yyou want to reutilize any piece of ass, where buttocks stands for some adequately sized space in memory -- entirely within the realm of possibility. Furthermore, evicting shit you don't need and replacing it with something else.
Let me tell you, I will give your every object an allocator if you give the chance. I will -- nevermind. This is not for your orifices, porridges, oranges, morpheousness.

I love it when a coding assignment is to take the last assignment and do one thing more optimized !!! 😄😄
All the hard stuff is already done and all I have to do is some optimization that I’ve done before in other languages and just have to implement in this one 😄6 -
The documentation of scala akka http may be just gibberish as far as I am concerned. You would think that hooking into the marshalling process (aka de/serialization) would be straight forward, I've dealt with similar problems before and solved it.
I have an object, it should be transformed into a Json and vice versa. Should be easy as pie.
Not with scala and akka-http. The docs tell you how to achieve something in dozen different ways yet lack a complete example. My first custom marshaller I created in a "marshall" package in my! namespace, but it was breaking scala compilation due to some black magic.
It's not clear how when and why marshallers are added, they just somehow are. Why do I have to deal with entity marshallers vs response marshallers. I just want each instance of a certain type to be transformed into a specific Json presentation.
Asking on stackoverflow also only yields in incomplete hints of "just do boargh" presupposing certain knowledge while sounding borderline condescending.
Currently, I just want to burn the project and rebuild it with fucking PHP. Flame all you want, at least I would get things done and the JMS serializer library has decent documentation and it works in an expected way.
Akka-http, combined with Scala, looks from my current rage-driven perspective like a solution worse than the problem. -
The rear ducking continues. We've built a reliable translator in the dumbest fucking way possible, it's just lovely. I simply reused the structure for feeding data to the VM assembler, an array of arrays, where there's one array of (ins [args]) per node in the parse tree.
It's nice because nodes can be solved out of order without affecting the actual sequence in which the instructions are output. And if one statement (node) equals multiple instructions, you just push multiple entries to the corresponding array, or push nothing if you need to output nothing. Easy as goblin pie.
This is enough to convert an input language to the assembly-like intermediate representation we use for the virtual machine. So then there's doing it backwards: walk the same array of arrays, and map those virtual instructions to a physical architechture. I guess I could do the encoding to native binary myself, it'd certainly be interesting to try, but I'm burnt-out already so I'll just use fasm for now.
Initial test: wrote a test program in my own stupid language, ran the translator, dump output to file, assemble that with fasm, run with r2 -d.
Crashes? No.
Runs fine? Yes and no.
For fuck's sake, I don't have syscalls. Mainly because the VM doesn't have an operating system, lmao. I was testing virtual programs by just freezing state, terminating, then dumping the fucking registers and stack to the console, we have no I/O to speak of. Not even a real 'exit', VM handles that by reading a return value every step like a mentally damaged son of a bitch.
So anyway, I manually paste the linux mambo, you know:
mov rax,60
mov rdi,0
syscall
And NOW our program can end execution without crashing.
Okay then, so does the test code work correctly?
** DRUM ROLL **
Yes.
Ladies and gentlemen, mother fucking PESO is now a compiled language, and going forward I will be expectantly receiving your marriage proposals for reviewing. Oh, but not so fast, we still need a frontend...
Well, we'll handle that in the next few days. I'm just glad to be *nearly* finished with this fucking compiler, I want nothing to do with anything else ever, but we know that's not going to happen, so Lord please end my pain.
No sponsor as this rant has been paid for by tax evasion. -
which type are you ??
**Manager:** Hey, we've got a little hiccup in the production environment. I know it's Friday evening and you're probably daydreaming about pizza, but could you give it a peek?
**Type 1:** Man, this is like finding a needle in a haystack while wearing sunglasses at night. Might take me a few hours... or days. But hey, wish me luck and have an epic weekend!
**Type 2:** Eureka! Found the gremlin. It looks like XYZ person tried to be a bit too creative on commit number 2234324. Maybe they had too much caffeine? Anyway, could you have a chat with them? And oh, may your weekend be as smooth as a fresh jar of peanut butter.
**Type 3:** Detective mode activated! Found the sneaky bug. It was XYZ person's "masterpiece" in commit number 2234324. But fear not! I've put on my superhero cape and fixed it in commit number 345453345.
**Type 4:** This issue again? It's like a recurring bad dream about forgetting your pants! I've revamped the whole thing so we don't have to relive this nightmare. If someone tries to pull this off again, our CI/CD will roast them like a marshmallow over a campfire.
**Type 5:** Ta-da! Fixed the glitch, jazzed up the design, and sprinkled in some extra logging magic. Now, troubleshooting will be as easy as pie. Speaking of which, I've got time for a coffee and maybe a slice of pie before heading out. Cheers!
Type 6 **Gloomy**: Oh, the digital clouds have gathered again. This issue is like a never-ending rain on a Monday morning. I've peered into the abyss of our code, and it's... well, it's deep and dark. I'll need some time, a flashlight, and maybe a comforting blanket. If you don't hear from me in a few hours, send in a search party with some hot cocoa.4
