Pic related is a piece of the project I'm currently working on. It's for my university, and it consists of a simple auction web site I'm writing with java servlets + tomcat server + mysql + thymeleaf (a templating engine)
I have to say that it's pretty interesting. It turned out surprisingly time-consuming to write, but I'm getting there... Oh and I'm extremely lucky good looks aren't a requirement, because I'm helpless at that
By the way, I wrote it following the architecture they explained to us during the course, but I never ran the code till it was entirely finished. And that's scary. Don't do it, I don't recommend it

Op here, just wanted to say that I hate dates to death.
In java (my backend language) there are 3 different built-in time libraries/types (For exact moments: java.sql.timestamp, java.util.Date, java.time.Instant)
But in case that wasn't enough, the most recent and recommended module, java.time, has a fuckton of different types of close meaning
>java.time.Instant - an instant in time
>java.time.ZonedDateTime - Also an instant, this time with timezone information
>java.time.LocalDateTime - Generic date and time, NOT a definite moment (depends on timezone, which is not stored)
>java.time.ZoneOffset - Literally a timezone offset. Not a timezone though! A single timezone can have two offsets due to dst
>java.time.ZoneID - This here is the Timezone
At this point I had gotten what I needed and thought my trials with dates were over. But then came javascript
It has just one type, Date, however it sucks fucking ass. All I want is for my application to assume "CET" timezone when reading and printing dates/times. Well, javascript's Date type doesn't have timezone info, instead that is used when printing/reading the date. Fine. But definitively it'll be easy to do that, right?
Well, JS just assumes your browser knows what's best, and if your browser has the wrong timezone setting... well suck a dick. And firefox browsers have wrong setting on purpose to fight trackers. Am I fucked? Well, there is a built-in library called "Intl" that allows for the programmer to work with timezones, but then older browsers go out the window. IE for example doesn't support jack shit. Why does this have to be so hard? Do I really need to plug in some third party "moment.js" library or implement timezone functionality myself?
Course not, fuck IE

 No.540[D][DF]

>>539
Small update: Intl is nothing more than a pretty print library. It's not actually usable for anything but printing stuff to the user.
I'll be implementing DST logic myself, thanks for sucking cocks javascript

So I've been thinking about switching to qutebrowser recently, and it's almost perfect for me. There's a couple issues like no Ublock Origin but I can get over those.
However, navigating 22chan doesn't work properly.
Opening a link to a post(such as >>2527 ) does nothing when I do it with the keyboard(press 'f' and choose the hint). I expect it to show me the post when I click on it, but instead it highlights it off-screen and I have to scroll down manually and find the highlighted post. Doing it with the mouse works for some reason. I'm switching to qutebrowser so I could do everything with the keyboard, so I might as well use firefox if that's the only way.

Any qutebrowser anons who've solved the issue?

How do you anons think the universe was created?
Do you think it was made by some higher power? Maybe a scientific phenomenon, or perhaps it was just always there.
All thoughts and beliefs are welcome, religion, scientific research or just personal beliefs, they're all just as valid to the question. After the universe was created, how did all the atoms and matter get there? What caused all of this matter to just appear? Excited to hear your thoughts.

A language is a tool. You should pick the best tool for the job you want to accomplish
...that being said I'm most efficient in python for most tasks I do, but the languages that really fascinate me are the ones that allow you to extend their syntax (like forths and lisps).

>my personal experience, how I found out about hacker culture
I was just a kid when I... sigh... became curious about becoming a "hacker", in the mainstream meaning of the term. The reason I think was that at the time I heard about the "Anonymous hacker group" and obviously was extremely fascinated by it. I mean, they were fighting for good, and were epic hackers! And they did it all from their bedrooms, and were otherwise pretty ordinary people like me!
Thing is, surprisingly enough on one of the websites which claimed to be associated with "Anonymous" I found a link to catb, specifically the "how to become a hacker" page
And that page encouraged me to learn more about programming languages, which had a big impact on me, as discovering langs other than java, python and c exposed me to new and different ideas that I probably wouldn't have heard much of otherwise until much later. It's also indirectly what got me into emacs. The culture itself really inspired me at the time too, and even though sadly I didn't become a hacker, I think those ideas influenced me growing up. Later my focus shifted to other things, and gradually I forgot about all this up until recently, when after revisiting some old places and reading some new things I made this thread
