Stack Overflow is full of abuntch of downvoteing dickbuts. The devrant community is so much more accepting of new devs, why not add a question section.

Down votes would only be allowed for spammers.
One the question was solved, it would go into the devrant question archive, Searchable by everyone.

Ik you have heard this one before, but it's Just my two cents.

Don't want devRant to become stack overflow but...

Feature request: mark as duplicate

This rant is particularly directed at web designers, front-end developers. If you match that, please do take a few minutes to read it, and read it once again.

Web 2.0. It's something that I hate. Particularly because the directive amongst webdesigners seems to be "client has plenty of resources anyway, and if they don't, they'll buy more anyway". I'd like to debunk that with an analogy that I've been thinking about for a while.

I've got one server in my home, with 8GB of RAM, 4 cores and ~4TB of storage. On it I'm running Proxmox, which is currently using about 4GB of RAM for about a dozen VM's and LXC containers. The VM's take the most RAM by far, while the LXC's are just glorified chroots (which nonetheless I find very intriguing due to their ability to run unprivileged). Average LXC takes just 60MB RAM, the amount for an init, the shell and the service(s) running in this LXC. Just like a chroot, but better.

On that host I expect to be able to run about 20-30 guests at this rate. On 4 cores and 8GB RAM. More extensive migration to LXC will improve this number over time. However, I'd like to go further. Once I've been able to build a Linux which was just a kernel and busybox, backed by the musl C library. The thing consumed only 13MB of RAM, which was a VM with its whole 13MB of RAM consumption being dedicated entirely to the kernel. I could probably optimize it further with modularization, but at the time I didn't due to its experimental nature. On a chroot, the kernel of the host is used, meaning that said setup in a chroot would border near the kB's of RAM consumption. The busybox shell would be its most important RAM consumer, which is negligible.

I don't want to settle with 20-30 VM's. I want to settle with hundreds or even thousands of LXC's on 8GB of RAM, as I've seen first-hand with my own builds that it's possible. That's something that's very important in webdesign. Browsers aren't all that different. More often than not, your website will share its resources with about 50-100 other tabs, because users forget to close their old tabs, are power users, looking things up on Stack Overflow, or whatever. Therefore that 8GB of RAM now reduces itself to about 80MB only. And then you've got modern web browsers which allocate their own process for each tab (at a certain amount, it seems to be limited at about 20-30 processes, but still).. and all of its memory required to render yours is duplicated into your designated 80MB. Let's say that 10MB is available for the website at most. This is a very liberal amount for a webserver to deal with per request, so let's stick with that, although in reality it'd probably be less.

10MB, the available RAM for the website you're trying to show. Of course, the total RAM of the user is comparatively huge, but your own chunk is much smaller than that. Optimization is key. Does your website really need that amount? In third-world countries where the internet bandwidth is still in the order of kB/s, 10MB is *very* liberal. Back in 2014 when I got into technology and webdesign, there was this rule of thumb that 7 seconds is usually when visitors click away. That'd translate into.. let's say, 10kB/s for third-world countries? 7 seconds makes that 70kB of available network bandwidth.

Web 2.0, taking 30+ seconds to load a web page, even on a broadband connection? Totally ridiculous. Make your website as fast as it can be, after all you're playing along with 50-100 other tabs. The faster, the better. The more lightweight, the better. If at all possible, please pursue this goal and make the Web a better place. Efficiency matters.

Any alternative to Googles reCAPTCHA?

Backstory we have a contact form, in a bootstrap modal, loading the form as an ajax request. The form has (as of today) a captcha, as we where getting a lot of spam.

Guess what it does on safari? Right... It renders outside the modal and since there's no need for scrolling, bootstraps modal adds an overflow hidden to the body. Results in non submitable forms on some resolutions.

Any idea on how to fix this, or other captcha systems we could use (it's a Symfony app).

So there is the webapp that the national post is using in Hungary. When you want to search a street in the given city you have to wait until the whole fucking list is populated and the street names are filtered afterwards. (I've got it he only wanted one request per street). But if that won't be enough the drop down menu is offset in some resolutions and the console is full of errors.

I can live with that even with the duplicate street name, but how dare you to publish an app with a search function that is unable to work with the special characters of the specific language? It's not even hard to make it work. You just a lazy ass dumbfuck who copy pasted something from stack overflow and didn't make the effort of testing it.

I mean I would probably jump off of a brifge if I would make such a huge mistake.

"DO NOT USE ISSUES FOR GENERAL SUPPORT.
Issues are for request only. You can use the following:

- Stack Overflow (using the "traefik" tag) (where no question excepted the simplest are ever answered)
- the Traefik community Slack channel (where no one is online)

...

So, what should I put as a title for my "issue"...

Stack Overflow people have profound buffallo bullcrap on their skulls, they are some software engineers who have fucked COBOL and BASIC, probably somewhere like NASA, just pondering out where someone post a question. They're probably some etilist cult banging a prostitute while delivering that awful downvote imitating the slap they give the chick during sex. They desire questions such as

"RANDOM_fuck_module_Abdul.method() not working in python" or "how to dock the dock by undocking" (tagged: AWS). Not things like "why does the audio tag not work in a PC but works in w3school tester?" or a genuine programming question. Fuck.

We don't tail recurse or loop abc for k in godfuck loops, huh? We make simple things as: a form, a http request to dell.

I hope there penises get rotten in the hell. Period.
this is just a part of SO.

So easy to DOS a whole software company.
Someone (accidentally) started a script or similar, generating so many requests on StackOverflow that our IP got banned.
In the company chat people already joking how they cannot work. This is "critical infrastructure" in 2018: faulty IP in our network is taken offline. Let's see if we can access SO again today.

OK I need some help. I need to make sure I’m not losing my mind.

We are using an ERP which is hosted by another company. We are supposed to be able to access the data via a REST API. This works fine using Insomnia or Postman, but when I attempt to hit the API from my web application, CORS blocks the localhost origin.

I contacted the company’s technical team to request that they change the CORS configuration to allow localhost. They keep running me around in circles telling me that I don’t know what I’m talking about because localhost isn’t a DNS resolvable name and I’m doing something wrong and they don’t need to change any configuration.

They insist that if anything would need white listed, it would be my IP, not localhost.

I sent them screenshots and stack overflow posts and documentation links, showing them exactly what headers need to be set and where the configuration needs to be set in the ERP. They tell me I don’t know what I’m talking about.

They tell me that if I can hit the API from Postman, I can hit it from my browser.

Am I losing my mind? Have I fundamentally misunderstood CORS all these years? I’m sure I’m right. But I’m starting to feel like I’m crazy.

From the last 3 years, i have accumulated interest and experience in android dev. Not sure about the future, but that's probably where i will be.
But this fact is moot to our 50 year old grumpy professors teaching 1000 year old rusted computer syllabus, who rejected my idea of a video streaming app as major project, simply because i projected it as a social media app, and "everyone is making a social media app, its such an old topic". yeah right sir, its younger than your daughter that fucks in the lobby

Now we are doing a project on file conversions website, a project suggested by my team member and my good friend. its such a shitty topic, there is no resources available, even the research papers are bad , every search points to a shitty site, and i don't know shit about web dev.

Technically i am the team leader, but my team mate won't let me make the project as android native app, because "Brooo, i am going to make a react app that would be completely offline, completely client side, full secure and shitt small" and sometimes "Bro its my idea" .

Well, 1. the whole point of client side is stupid because the 18 mb jsfile isn't going to get downloaded first in the client's cache(or whatever the process is, idk). The top stack overflow answers i saw told me to buy an ec2 instance and run liberoffice commands on it for every request, and that's SERVER SIDE. even if we could, i am sure its going to be bigger than what i would have made in kotlin.
2. what am i supposed to do? look at you coding while make all the ppts and research paper? you are going to use undocumented libs that "just works" , and i am suppose to curate the theory behind this, looking at all the researches of the world?well i guess okay that's a light job since THERE AREN'T ANY.

And we are targetting all types of conversions, nice. from what i know, handbrake.fr: video conversion s/w = 16 mb. photoshop: image conversion s/w=1gb and ms word: doc to pdf/other formats= 500mb.
Plus all those proprietary and undocumented formats, ugh. Thank you ugly ass companies.

Internet is great but web dev has become a whole lot mess. "I am going to build a software that is going to run in your system only using your device's processor" is a desktop/mobile app, not a website

I'm in need of advice. I reckon this is no stack overflow but that's probably for the best as I wouldn't feel as comfortable posting there as I am doing it here. So, back to the question: I'm currently working with legacy code, written in .NET 2.0. This code is responsible for calling upon PEC services in order to finally create personal smart cards. I was tasked with the job of creating a repository system that would allow the program to call on the old legacy services or the new ones without any distinction. We are talking about SOAP services in both cases. The issues is: the new service definition is comprised of soap policies. This wouldn't be a problem per se, with more modern version of the framework, but with .NET 2.0? Yes, it is. It doesn't support policies and signing the body with a certificate right out of the box. How can I manage this? I feel like the only way would be letting the proxy class do its thing up until the very last moment: intercept the SOAP request before its sent and modify it according to the specifications. But I reckon this is very bad practice. Is there any other way out of this?

Thanks for anyone that would like to help. 🙂

How can I store a request context without passing a ctx param down the function stack?
