Front-end dev: email domains other than Gmail and Hotmail exist?!1! 😱 And email regex, what the hell is that? 😵

Writing Regex be like..

Had an interview in a MNC company.

He: Propose a solution for reading huge logs file like 1 GB and parse errors with today's date.

Me: Gave two solution, one with regex and second with buffering the logs (reason: reading the entire in same shot will cause cpu spike with huge memory consumption) and I fell in love with my second approach. By the way it was on paper.

He: (Without seeing the logic) Your syntax is wrong.

Me: Got frustrated who the hell checks syntax in interview. I asked how may years of experience you have?

He: 10 years.

Me: I don't wanna continue, and I left.

The gift that keeps on giving...
When you think you've seen it all after 7 months in legacy hell, you get another gift:

Let's say you use PHP, but your IQ is in the zero-ish range, then it is obvious to:
- use define() for constants in all your config.*.php files
- then include said config.*.php files multiple times
- and because define() doesn't overwrite the same constant, because it's - you know - a constant, you instead of including just do a file_get_contents() to read the PHP file as string and then parse the values by Regex.

The dev who wrote this was truly one of the devs ever.

Me: *opens FB in mobile web browser*
FB: You there! Go ans get our great Facebook Lite app! It is faster and...
Me: Nope! *clicks X to dismiss*
FB: Nope! *a wild code appeared*

When you forgot to escape characters in regex and wonder why the fuck it’s not working for 2 hours. 😖

Why regex must you be a living hell!

I spent almost 10 hours coming up with this RegEx. Trial and erroring my way to hell. First I had get rid of the HTML tags (which was easy-ish) then I spent most of my time trying to figure out how to remove the god damn dash but keep hyphenated words ....... Then I found \B and look behinds...

I am making it a point to get good at this shit... Because right now I am petrified of it... Fuck you Regular expression you have taken away all my emotions...

Ah, yes, their built-in bullshit newsletter module just sent the n-th user n emails. Wonderful considering n=368.

The culprit? Better don't ask...
OK, anyway: So the mailer is running as a CRONjob, but nah, not as a console script call but by a public HTTP GET URL call, fucking obviously (it's the CMS Of Doom for a reason).
So these fucking imbeciles "implemented" an ob_start() callback where HTML links are - for whatever fucking reason - modified by some regex (obviously everybody knows parsing HTML by Regex is trivial). In this case the link was somehow modified to recall the mailer Cronjob...
This must have upset the pngoing mailing process thus spamming mails. Whyyyy

And I've thought I've seen it all after 6 months in this legacy hell...
This is why you don't run a company consisting of only beginners in PHP (in cluding their "CEO")!

What are you doing crashing on me Windows?

All I was doing was running a flight simulation, compiling a build, and doing a regex search over 6 directories. Try to open one little document and it all goes to hell.

Surely you can handle that Windows?

Apparently not.

Regex is fun 😃 NOT!!! 🤯😭

How do you get over the bad times? I keep having to work with shitty legacy systems that were written in perl and flash in the 90s, but my boss keeps telling me "No" on redoing some of the bigger stuff even though it is really needed. I mean, that is your goal here, right? Rebuilding this POS? FFS you still stored passwords in plain text twoo weeks ago! But no, you's rather dig around in Perl than upset some random user because his fucking interface looks different.

But then I also have to work with another system that I could redo in Cake/Laravel in two weeks (it's literally getting and writing data to one table, so two views and user auth), and the previous dev just... made a huge mess. I mean, why would you need to post data asynchronously when it's this one stupid form ? Just do a regular form submit? And the system is really not suitable for extending, because everything is in the database, EVERYTHING! Like, html form inputs? So to add a simple input to the template I have to create a new input type in the types table and then add that to the form structure table? Only to have the input checked by fucking regex? REGEX! Why? Seriously, this is not some high end CMS that needs this level of code reusability No. This is a simple fucking form.

And I can't get it to work. No documentation of course. No comments, either. All of this makes me feel like I'm just the shittiest dev ever. I feel dumb, and useless. Haven't turned on my private PC in weeks because I see no reason to work on any of my own stuff.

I used to have a job, working with Magento and Wordpress. And yeah, it was horrible, it was chaos, but it was fun and I was great at it. I bent that motherfucking system to fit my needs. People respected my opinion, they were convinced I could program this and that, and I proved them right. Did I make mistakes? Hell yeah. Did I give up? Fuck no!

But now, I just feel like I can't even write a simple fucking form any more. I'm just so close to giving up on development as a whole, even though I love it so much.

Some of you know I'm an amateur programmer (ok, you all do). But recently I decided I'm gonna go for a career in it.

I thought projects to demo what I know were important, but everything I've seen so far says otherwise. Seems like the most important thing to hiring managers is knowing how to solve small, arbitrary problems. Specifics can be learned and a lot of 'requirements' are actually optional to scare off wannabes and tryhards looking for a sweet paycheck.

So I've gone back, dusted off all the areas where I'm rusty (curse you regex!), and am relearning, properly. Flash cards and all. Getting the essentials committed to memory, instead of fumbling through, and having to look at docs every five minutes to remember how to do something because I switch languages, frameworks, and tooling so often. Really committing toward one set of technologies and drilling the fundamentals.

Would you say this is the correct approach to gaining a position in 2020, for a junior dev?
I know for a long time, 'entry level' positions didn't really exist, but from what I'm hearing around the net, thats changing.

Heres what I'm learning (or relearning since I've used em only occasionally):

* Git (small personal projects, only used it a few times)
* SQL
* Backend (Flask, Django)
* Frontend (React)
* Testing with Cypress or Jest

Any of you have further recommendations?

Gulp? Grunt? Are these considered 'matter of course' (simply expected), or learn-as-you for a beginner like myself?

Is knowing the agile 'manifesto' (whatever that means) by heart really considered a big deal?

What about the basics of BDD and XP?

Is knowing how to properly write user-stories worth a damn or considered a waste of time to managers?

Am I going to be tested on obscure minutiae like little-used yarn/npm commands?

Would it be considered a bonus to have all the various HTTP codes memorized? I mean thats probably a great idea, but is that an absolute requirement for newbies, or something you learn as you practice?

During interviews, is there an emphasis on speed or correctness? I'm nitpicky, like to write cleanly commented code, and prefer to have documentation open at all times.
Am I going to, eh, 'lose points' for relying on documentation during an interview?

I'm an average programmer on my good days, and the only thing I really have going for me is a *weird* combination of ADD and autism-like focus that basically neutralize each other. The only other skill I have is talking at people's own level to gauge what they need and understand. Unfortunately, and contrary to the grifter persona I present for lulz, I hate selling, let alone grifting.
Otherwise I would have enjoyed telemarketing way more and wouldn't even be asking this question. But thankfully I escaped that hell and am now here, asking for your timeless nuggets of bitter wisdom.

What are truly *entry level* web developers *expected* to know, *right out the gate*, obviously besides the language they're using?

Also, what is the language they use to program websites? It's like java right? I need to know. I'm in an interview RIGHT now and they left me alone with a PC for 30 minutes. I've been surfing pornhub for the last 25 minutes. I figure the answer should take about 5 minutes, could you help me out and copypasta it?

Okay, okay, I'm kidding, I couldn't help myself. The rest of the questions are serious and I'd love to know what your opinions are on what is important for web developers in 2020, especially entry level developers.

Spend several months designing an alternative approach to string matching/parsing not based on parser combination or Regex. Benchmark and profile the ever living hell out of it. Find out the performance is highly competitive with FParsec and far easier on memory than either approach. Discover FParsec responds very badly when failing. Document all of this, do a presentation on the design. Upload video of presentation with links to it on a few sites. Presentation gets downvoted, and receive hatemail. Yay.
