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.

I am in love with regex (re in py)!
It is so damn cool!
Unfortunately, Python's find is faster.
But regex is so much better when it comes to complex patterns you would not be able to find with the regular (do you see the pun here? ;)) python's string object find method.

I used to doubt the usefulness of regex, until now.
I'm new to web dev, and downloaded a sample website to make a project with, but all the sources of images came as src="images/image.jpg", and for some reason I couldn't make it work, the only way that I found that could work to me was creating a static folder inside my app folder, declaring in the start of the document a {% load static %} and referring the image source as {% static 'images/image.jpg' %} in the html file, I kinda get what this is doing, but why it's the only way that works, it's beyond me.

Great! Now I can start the development server and see the website in its full glory!!! Then I realized: I had to edit the sources of every image and every reference to css and js in 5 html files to it work properly, and come on, do all that by hand?

Then regex came to mind, never had used it, never knew how to use it properly, after some web research I found if I did a find/replace with ([a-z]\w+\/[a-z,-]+\.[a-z]+{1,2}) and {% static '$1' %}, all the work I had to do, was resumed to a single click of replace all.

Man, I love doing what I do, and I love you guys/gals, never tough I would ever find a place in which I could share this kind of thing!

Started new course called "Introduction to natural language processing" in uni. I am super bad at doing regular expressions and don't understand anything about them.

Saw the first weeks homework. Have to do i.e. some text cleanup with regex... I was sad. But now after reading the course material and trying some of the exercises I'm super excited since I'm actually doing something "real" with it.

Do you guys just love it when teaching material is well written? I do.

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.

Every once in a while I come across a challenge that's actually challenging. Most recently ... "Develop Regex for validating and extracting a recipe's ingredient's quantity"

Regex should properly identify the numbers in each of the following lines:

1 cup of ingredient
Diced 1/2 cup of ingredient
.5 tsp of ingredient
1 1/2 packed cup of ingredient
1.5 cup of Heavy whipping cream

My answer is the first comment in case you want to solve it yourself. I'd love to know what others come up with.
