Frontend & backend dev conversation

Backend Dev: what will you be working on?
Frontend dev: i will be creating a nice animated loader. You?
Backend Dev: i will be working on optimizing the backend so that no one can see your loader.

🤣🤣🤣🤣

So I decided to give Linux a try again.

Created live usb. Prepared myself to go through all the hassles at the beginning.

Booted in live USB. I can't see mouse cursor.

Searched in google, apparently a common problem with GTX 1070/1080 graphics cards.

Installed proprietary nvidia drivers with keyboard only. Took me about 20 minutes.

Finally managed to get the mouse cursor and install ubuntu. Time to boot and smell the fresh air of linux again.

Sound card doesn't work. Even the integrated mobo sound card doesn't work. Looked for a solution, found the bug in lunchpad but not solution yet. Everyone recommending to buy an external sound card.

I can't code without music. Decided to remove linux.

Booted back to Windows and removed linux partition. That fucked up my bootloader although I installed linux's efi loader completely separately.

Now I am sitting in front of my computer, with black grub screen, while trying to make a Windows 10 usb with my 7 years old broken laptop.

Next time I see a rant about Windows 10 that glorifies linux, I swear I'm gonna smack your face over standard TCP/IP

Me: Well, it's time to make a new app!

Some genius at apple:

I know, let's have a wireless mouse and when something goes wrong with the boot loader let's put a button there to restart the machine but not select it, also don't load the drivers for the wireless mouse so the user has to plug in a wired mouse to click the button

Me: what an absolute donkey dick of an OS. I will replace you with rasbrian...

Me: *spends 4+ hours refactoring existing spaghetti, ensuring components are modular, easier to test and fault tolerant*

Project manager: ...

Also me: *adds pre-loader image to register and login buttons when user submits form*

Project manager: *All excited* Awesome work. 🙌That's some nice improvement..

Like wtf dude 😳..

My takeaway: These noobs only care about what they can directly interact with

The fun I'm having is currently overwhelming.

Eclipse new loader

Same situation as my previous rant.

Was building the dynamic page loader thing (basically mvc part) but it just DIDN'T FUCKING WORK.

As a last resort I chose the views to render based on a few if-else's 😅

Hacky as hell but it saved me from doom!

"Sooo, children of the village, what are we going to write front-end in?" - I said to my infant students.
"Typescript with ts-loader/awesometypescript loader for webpack" - simultaneously yelled the kids.
"Exactly! Brilliant! And now, what are we going to be writing back-end in?" - asked I then.
The kids yelled: "PHP 7.2 with Laravel, or Go with Gingonic and juliensmith/httprouter, or Typescript without loader, with express/koa"
Truly stunned with their excellence, I asked "Well, now you 100% ain't gonna get it right - what are we going to be writing a desktop application that doesn't require a lot of native functionality and preferably, cross-platform in?" And the kids didn't hesitate to yell happily "Typescript targeting Electron", which has only brought tear to my eye.
"A native ms windows app?" "WPF under C#"
"A native gtk app?" "Vala"
"A native KDE/XFCE app?" "Cpp/Qt"
"A native mac app?" "Swift3.2/4"
I was in tears, just thinking about what future these kids have, but suddenly I have noticed one of kids seemed puzzled. It was Pajeet, an indian guy, ugh, his mom was a bitch. I asked him "What is wrong, little acoustic?" "But I like Java, and I would like to make back-end with Tomcat!" he replied. "Ooooh :3" cutely I moaned, trying to reach the handle of the table locker "I've got something just for you". I pulled out a rope, with sewed-in spikes, covered in drool and piss, came up to Pajeet and tenderly put it around his neck, making a knot. Pajeet fell under the table, and I got fired.

That moment when I read "sass-loader" as "ass-loader" (҂⌣̀_⌣́)

As a total noobass with Linux I tried installing Arch. Why the fuck did I do that.

I fucked up the drive partitions, deleted the Windows boot loader and now neither Windows nor Arch fucking loads.

Can this get any worse

Dear fellow JS devs, if you make 1 more good damn module loader I swear to god....

Hi - here's a new module bundler named parcel.

FFS

The story of the shittiest, FUCKING WORST day of work.

TLDR: shitty day at work, car crash to end the day.

So, let tell you about what could possibly be the worst day I had since I started working.

This morning, my alarm didn't work, woke up 30 minutes before an appointment I had with a client.

Arrived late at the client, as I start deploying. They don't have any way to transfer the deployment package to the secured server. Lost 45 minutes there.

Deployment goes pretty well. My client asks me to stay while they load some data into the app. Everything's pretty easy to work out. Just need to input 3 CSV with the correct format (which the client defined since the beginning).
I end up watching an Excel Macro called "Brigitte" (I'm not fucking kinding, could'nt have thought of that) work for 4 hours straight. Files are badly formatted and don't work.

Troubbleshooting thoses files with a fucking loader that does not tell you anything about why it failed (our fault on that one)

I leave the client at 7:30pm, going back at work, leave at 9pm.

At this point, I just want to buy some food, go home and watch series.

But NO, A FUCKING MORRON OF A BUS DRIVER had to switch lanes as I was overtaking him. Getting me crushed between the bus and the concrete blocks.

Cops were fucking dickheads, being very mean even tho I was still shaking from the adrenaline.

In conclusion, the day could have been worst. The devs at the clients are pretty cool guys and we actually had some fun troubleshooting. At work, there was still one of my colleagues who cheered me up telling me about his day.
And when I think of it, I could have got really hurt (or even worst) in the crash.

A bad day is a bad day, tomorrow morning I'm still going to get up and go to a job I love, with people I love working with.

Very big rant (sorry about that if someone's still reading)

I want a KVM switch for sata cables. That way I could switch between ssd’s without having the other visible.

Win10 could no longer randomly rewrite the boot loader(s) or wipe my Linux drive.

I’m not a fan of win10, and don’t currently have it installed, but might cave for a few rare games that I can’t get working via proton.

Errors be like "Source.ts 44:38", Source.ts has 28 lines. Alrighty.

I accidentally deleted my boot loader and now my PC won't start. I tried boot repair but no hope. I don't have a win backup either

So I hate apple, we were updating an app from a year ago and everything went well until we tried to submit. We kept getting this error about launch screen images for iPhone 5. We tried everything stack overflow had to say but nothing worked, NOTHING.

Here is the thing, we tried to submit the exact same binary on our other Mac, and it worked. LIKE WHAT THE FUCK APPLE.

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!

Ok what idiot calls a spinner loader element circular-progress__graphic? WHO?!

When your plugins list in your newly "coded" WordPress site could use an infinity loader, that means you are probably​ one of those fucking two weeks fucking coding bootcamps miracles. Fuck, that's not how the website is done...

To whoever builds electron boilerplates.

STOP ADDING FUCKING JQUERRY AND WEBPACK TO THIS SHIT, I DONT EVEN USE YOUR BULLSHIT BUT OTHERS DO AND THATS WHY SO MANY ELECTRON APPS SUCK. WHO IN THEIR RIGHT MIND THINKS THAT THIS MADE SENSE PUT YOUR CSS LOADER ANAL PLUG IN TO YOUR ANUS AND BUNDLE THEM TO YOUR SINGLUAR BDSM.JS WITH BROWSER BACKFALLS AND BETTER MAKE SURE TO WHIPE YOUR DIRTY SHITFACE WITH A FULL BLOW CSS RESET BETTER MAKE SURE THERE IS NO ACCIDENTAL MOZILLA STYLE IN YOUR CHROME.

A toss up between COSMOS or the Linux kernel, COSMOS because it's just amazing to see an open source kernel built on .NET from scratch (besides boot loader) and Linux kernel because well... Do I need to explain?

Just gonna leave this here because I am too lazy to write a proper article for my website:
If anyone is trying to create a Vue.js website with Node.js backend do NOT use express-vue, it is unnecessarily complicated and broken. Instead use this method I found.
You will need:
- IntelliJ IDEA / WebStorm / other IDE supporting multiple modules per project and tasks
- Nodejs and npm
- vue-cli

Step by step:
1. Create new empty project
2. Add your frontend module using vue-cli generator
3. Add your backend module using Express generator
4. Run npm build in your frontend module once
5. Move or remove public folder in your backend module
6. Create a symlink from your backend module root called public pointing to dist folder in your frontend module root
7. Make sure to add "Run npm build" from frontend module to your "bin/www" task (default task for Express module)
8. Enjoy developing your REST API in Node/Express and your frontend in Vue.js with single-file components and it being served by the same server that is providing the backend.
(Since they are separate modules and you are not mixing webpack and Node/Express you can add ts-loader, stylus-loader, pug-loader or any other loaders without screwing anything up)

For deployment you just need to copy the contents of dist into public on the server. (and not upload the symlink)

Being a front end developer and working in a team of motivated "full stack" developers sucks big time.
So, recently joined this new company with a very small project which just started, basically a cloud version of a really old desktop app. Few people from the team completely from the asp dotnet background decided the architecture few months before I joined in.
So, they did it something like this -

- mono repo dotnet project with VueJs app served within it (because that would be maintainable 😑)
- vue app served by pointing the built files through dotnet index file (simply because they didn't care about the gift to the front end world which is webpack or even had any knowledge about it 😑)
- added typescript because, u know it's cool 😑, without even knowing that they don't possess that team which know how to write the types (f***ers write classes for every payload object coz they don't know what interfaces are)
- no loader to load typescript, they are running tsc in watch mode and we have .js and .js.map for every .ts file in our project which some teammates are even pushing to repo

Recently, I added eslint with git hooks to the project so that everyone will at least stick to the coding standards. Now, to avoid the errors they are bypassing the git hooks by uninstalling the library and then installing it after the commit😂😂
Then we have a girl who uses document.getElementById to programmatically change styles in a Vue project😑😑😑😂
Then we have dotnet people using dotnet coding conventions all over the front end app.

People, how do I deal with these so called "full stack" people?

I've decided to switch my engine from OpenGL to Vulkan and my god damn brain hurts

Loader -> Instance -> Physical Devices -> Logical Device (Layers | Features | Extensions) | Queue Family (Count | Flags) -> Queues | Command Pools -> Command Buffers

Of course each queue family only supports some commands (graphics, compute, transfer, etc.) and everything is asynchronous so it needs explicit synchronization (both on the cpu and with gpu semaphores) too

I'm unable to upload archives thru Xcode ever since I updated to version 8.2.1. Updating to 8.3.3 didn't help either. I always have to use application loader.

Omg I loath path separators. Been working on windows most of the time (bought a surface pro for some reason) and my colleagues work on Linux. We just do standard web dev stuff nothing special but. I started having issues with my windows build getting weird function.prototype.bind.apply is not a constructor issue. Which is valid because apparently my colleagues started using the fat arrow function everywhere and on places where not needed.......

But on Linux they never had an issue because babel fixed it to the old function during the transpileee. So why the fuck am I getting this problem. After some tedious debugging and asking my colleagues. (colleagues only responded with just use Linux) I found the the issue to lie in the webpack loader for the Javascript in which the path regex used a single / :(. So I changed that to a group to be / or // and bam the whole bloody project works on windows now.

....... My colleagues still don't understand that they over use the fat arrow in the wrong places unfortunately

I JUST CAN NOT UPDATE THAT ONE SERVER TO DEBIAN 9

- it has no /dev/sda but a /dev/ploopXXXXX which is mounted as / but I can't see it
- uname says it's Linux 2.6.32-042stab126.2 and it says Debian some lines later in the ssh login
- there is no boot loader (I can't find it)
- lsb_release tells me it's running Debian 9.6 stretch, I put stretch into the apt sources
- in /boot there are 2 different versions: 3.16.0-7-amd64 and 4.9.0-8-amd64
- and I do not have physical access to it

WHAT THE FUCK AM I SUPPOSED TO DO?!

I wanted to install OpenVPN on it but that Linux Version doesn't support the Tunnel Interface /dev/net/tun

Here some more information to despise Apple.

In the past few weeks I keep having a problem making the iMac connect to whatever website/host, so I had to rerun whatever I had to do: fetching from github, push to github, connecting to a LAN server, pinging to know to IP, accessing a webpage and so on.
Luckily enough, browsers tend to request again if an error occurs.

At my job, I upload app files to servers, like GooglePlay and AppStoreConnect.

For those who don't know, Google makes you upload the app through the browser (among other ways) while Apple requires you to upload your app either through XCode. No other possible ways.

Whenever XCode requires an update, the authentication is required, but the authentication server cannot be reached for at least 5-6 tries.
Then I have to upload the app and just to be ready to hit the "upload button" it takes like 3-4 minutes, which might be completely useless if a network error occurs.

How hard is it to make your fucking app-loader to try again at least a few times?

First "computer" : Electronika BK. Had some fun with table software and some basic

first X86 : Intel 80286 with wooping 1MB of ram and 40 MB hard drive.

First fun experiance :

Me : "I'm gonna clean folders"
Me : "What are these files on the c: ? I'll move them into a folder"
(Youknow like io.sys, autoexec.bat)
Reboots :
Computer : "Please insert a boot drive"
Me : "The what now?"
Needed some help to fix it.
At least I learnt how boot loader works and wrote my own small thingy in asm

I used some kind of application on a compact disc (don't remember what it was) and it asked to reboot in order to do some stuff before Windows loads. Apparently in order to do so it overwrote MBR along with my TrueCrypt loader. Didn't make rescue disc, so lost about 300GB of stuff.

Stop using loader on your fuvking wordpress website please.
Can't believe I waited over 3 minutes plus and your crappy site is just showing me a spinning image.
Like who the fuck has such time.
Time to press the close button!!
😡😡😡

The real web development is optimising the shitty front end code.
The task assigned to me is optimisation of dashboard page of website which was developed by freenlancers.(end of contract from their side)
The front end is mess. Individual js files (bootstrap, popper, jQuery, jQuery ui, loader and main) loading in production inside head tag of html file
No text compression.
Every template has random number of their own js files in any block of template. Nothing structured. There will be fantastic waste of time figuring out file dependencies.
Same with css files. Some are scss, some plain css. No compression. No proper modules.
Basically, I have to go through 25-30 html files. Then understand, which template is extending which one. Go through all js and css files in each html file and again understand dependencies between them
This is gonna be real fun.

Idea for a project:

Inspired by BlockAdBlock, what if we do a format-minifier loader for webpack? It'll take your minified JavaScript, and format it by filling it with newlines and spaces? It'll also try to guess the functionality of the variables and functions to name them. Ex:

function f(a, b){return a + b;}
// would turn into:
sum(summand, addend){
return summand + addend
}

but also:

function f(a) {
if( window.innerWidth / window.innerHeight > 700){
a.width = 4
a.height = 5
} else {
a.width = 5
a.height = 5
}
}
// would be renamed to...
function ifWindowInnerWidthDividedByWindowInnerHeightThenObjWithHeightAndWidthHeightEqualTo500ObjWithHeightAndWidthWidthEqualTo400ElseObjWithHeightAndWidthHeightEqualTo300ObjWithHeightAndWidthWidthEqualTo500( objWithHeightAndWidth ) {
if( window.innerWidth / window.innerHeight > 700){
objWithHeightAndWidth.height = 500
objWithHeightAndWidth.width = 300
} else {
objWithHeightAndWidth.height = 300
objWithHeightAndWidth.width = 500
}
}

Imma get famous

Before my vacation I’d been chatting with one of our dbas about an etl tool we needed for a customer we’d already signed all the contracts with saying we would provide one for a historical database of old data. They had been looking at one from SAP but in typical fashion a license was worth more than the actual contract.

Anyway long story short on the weekend before I went back to work I rattled together a little python proof of concept using a couple of azure databases and when I went back demo’d it to the pm and dba they loved it and we built on the poc to have a working loader which saved us about £30k by not buying the SAP product and just wrote our own.

Stop useing lazy loaders, every time you use a lazy loader a kitten dies.

I need a money-loader for webpack

F Apple. I've got their touch-driven, motion-sensing, centimeter-thick, supercomputer (by 1990 standards) from 2012, and I can't fscking run Linux on it because my only official choices are the old iOS 7.0.0 over-the-air update and the newest iOS 9.3.5, and no one has published how to get root to either stupid OS so I can run an exploit on the stupid fucking boot loader.

Try to upload ipa archive to iTunes. Service is interrupted. Again. Fuck you apple! I was trying to upload that fuck for six damn u punk ass times. Why apple? Fuck you! I'll put the archive on a stick an ram it right into your ass you shitty fuck! JUST TAKE MY BINARY RIGHT NOW!

Don't take it to serious. I'm okay 😎

(heading)How a programming language is created? Because I want to make my own.(heading)

I am learning C and next I will learn C++, SQL,DS&A, Assembley, Lex&Yacc,Operating Systems, Computer Arcticture, Computer Networks because I think it's enough for my goal. The only reason I am learning this, to make my own C++ clone with my own knowledge. But I really don't know how can I create my own programming language like C++ from scratch. Like what are the first steps to began with. As I know that C, first step is Preprocessor then Compiler then Assembler then (Loader/Linker).

Anyone please give me a step by step guide like learn this language first then this then this. So I can finally reach that amount of knowledge which I can implement to create my own programming language like C++.

Can I say Ubuntu installation has really gone messy lately(at least the last time when I installed back in 2009). Especially the part of disk partition and selection. You get only three options - Install alongside Windows(without additional customisation), Install on the whole disk, and then Custom.

Most times these days people will select Custom and configure the partitions. And then the crucial part is selection of Boot Loader. But it's not given much focus which is empirical because otherwise even if your installation is successful, without the correct Bootloader config, you will continue to boot into Windows and then debugging and fixing gets really tricky. Especially for somebody who wants to try it out.

And then you will be cursing yourself to have bought a laptop with Nvidia graphics card because the drivers are proprietary and sometimes they have you stuck in Blank Screens prior to login. Ubuntu is not at fault here, but then it makes the life of people trying out things so much more difficult that will force people to just give it up.

I had moved to CentOS(because of Gnome) back in 2015 after really squeezing everything out of Ubuntu 9.04 on my Intel Core 2 Quad. And today, I installed Ubuntu 20.04 after almost 11+ years and it was really not a good experience.

Any idea how to run ASI loaders for games like Mafia or GTA San Andreas via Wine? (Especially Mafia, cuz I wanna apply widescreen fix)

When you are creating an account on devRant and want to use copy and paste on an iPhone with German language selected...

Last night I wasted over an hour fiddling with efibootmgr, because newly created boot-entries got removed after a reboot.
Turns out, my latops uefi auto deletes entries with a missing loader and it recognised them as such, because I had a typo in the kernel-name.

I just got a new laptop and wanted to dual boot Linux on it.

Everything seemed fine until I realized the laptop had UEFI. I always used easyBCD but this won't work sadly. MS blocked some features.

Any alternatives?
What boot loader do you guys use for dual booting Linux that works with UEFI?

Thanks in advance!

Though I’ve seen devices like the following I’ve only ever seen them used for horrible purposes.

I was envisioning facility control being made capable by the use of a larger tablet device or tablet computer. The device would have no internet connection. It would not attach to the outside world at all.

It would not receive non manual software updates

It could view all air flow, temperature, lights, locks, electrical outlets, power draw, water usage, heaters, air conditioners, computer statins etc
And control and report statistics on them all.

Impractical you people said last time. But I would say cool if the device is kept super secure . That being said who knows how to do that since everything sucks once someone who knows what they’re doing has physical access lol

Personally all I don’t know how to break into is smart phones
Comps I could always figure out even if they had disk encryption given enough time.

The only reason phones are hard is you’re limited to network attacks and the boot loader is on the chip page.

Cause in the end a computer is just it’s hard drive in terms of security lol

Business team has been chasing an issue with a report we generate, which I've sort of been dragged into because I worked on a loader for data they need.

Another guy is responsible though for the report and they had a meeting with user to iron out it last week...

I would expect the guy to ask me for guidance, essentially needs to rewrite it duplicate the loader but haven't heard a peep from him...

I guess I'll let him deal with his own shit and extricate myself from their discussion

when simply focusing a control doesn't work coz of some freakin video loader keeps getting active when played!! ohhhh I love debugging!!!

Stop screen on a widget test

I have a screen which contains a button,

Pressing the button will
1. call a function showloader() to show progress indicator,

2. then awaits to perform some logic.

3. Then calls function hideLoader() to hide the progress indicator.

My question is how do I perform widget test on loader, the problem is when I do tester.pump() it gives timer error and when I do tester.pumpAndSettle() it will go ahead and call hideLoader() and the indicator gets lost and finder cannot find any widget and test fails?

Is there any way of stopping a screen on execution, so that finder can find a widget?

I have never seen core coding questions here so this is one of my shots in the dark-- this time, because I have a phobia for stackoverflow, and specifically, discussing this objective among wider audience

Here it goes: Ever since elon musk overpriced twitter apis, the 3rd-party app I used to unfollow non-followers broke. So I wrote a nifty crawler that cycles through those following me and fish out traitors who found me unpleasant enough to unfollow. Script works fine, I suspect, because I have a small amount I'm following

The challenge lies in me preemptively trying to delete some of the elements before the dom can overflow. Realistically, you want to do this every 1000 rows or so. The problem is, tampering with the rows causes the page's lazy loader to break. Apparently, it has some indicator somewhere using information on one of the rows to determine details of the next fetch

I've tried doing many things when we reach that batch limit:

1) wiping either the first or last
2) wiping only even rows
3) logging read rows and wiping them when it reaches batch limit
4) Emptying or hiding them
5) Accessing siblings of the last element and wiping them

I've tried adding custom selectors to the incoming nodes but something funny occurs. During each iteration, at some point, their `.length` gets reset, implying those selectors were removed or the contents were transferred to another element. I set the MutationObserver to track changes but it fetches nothing

I hope there are no twitter devs here cuz I went great pains to decipher their classes. I don't want them throwing another cog that would disrupt the crawler. So you can post any suggestions you have that could work and I will try it out. Or if it's impossible to assist without running the code, I will have no choice but to post it here

npm, a package manager so retarded it is too stupid to do it's one and only job. To install dependencies. The real funny part is, half of the dependencies are already installed globally, but npm doesn't know. Because npm is indeed **the worst**. npm developers should all have been a trimester abortion, but now it's too late and we have to pretend we like them. No I don't! Fuck them and npm
