How do you people stay productive on your thinkpads(laptops)? I'm a desktop user, I use my desktop fucking 16 hours a day. Even though my laptop is 1080p I still feel cramped on it and I can't get anything done. I'm considering a little 13" USB monitor for it but I'll look a sperg using that in college and I'm already kinda fat and dress like a poor so

>>59939751
I have a thinkpad with 1280x800 resolution and it's not difficult at all.
I don't even use workspaces, I just alt+tab between open windows.

Have you ever tried programming on a phone?

I move a lot so a desktop was impractical for me, now I just do my job normally on my 15 inch 1080p laptop.

Can you recommend any UTF-8 characters that look like "n" and "N" other than 6E and 4E? I need a replacement for these letters that wouldn't be noticed unless you looked at the code, I don't care if it looks funny it Times New Roman or some other font like that, I'm doing a thing in monospace and with little pixel density.

>>59939826
Does it matter? Any use would be sufficient to say that it's useful.

>>59939808
I mean I can do it but in general it's just not enjoyable. Maybe I'll try to use my laptop more at home to get used to it. I only use it at school, the second I get in the door I plop down at my desktop, yet whenever I take out my laptop I think to myself "damn this thing is so nice why don't I use it more"
You know, it's not just programming either, pretty much anything that isn't 4chan I suck at on the laptop. Even just working on multiple choice questions, it feels way way slower than on my desktop.

Is modulo expensive, or can I assume all CPUs do the intel thing where integer division always produces a dividend + remainder and the remainder is fetched instead of the dividend?

>>59939940
I don't, I have a vague interest in it at best. More interested in hardware. Problems are banal because I go to great lengths to live as simple a life as possible. I keep no one around so I don't have to answer to anyone or explain myself. I'll lose weight if I ever decide to get a girlfriend, comfy right now.

That would defeat the whole purpose though, I live like this so I don't have to worry about maintaining appearances or relationships. I suppose I'll have to clean up when I start looking for work. Nothing wrong with having a conversation. Do you program for fun? I'm just lacking motivation lately. It's definitely enjoyable, nothing rivals finally getting something to run or compile.
Maybe that's the ticket guys. Program like people play video games until you become a master at it like a WoW nerd is a master. They know everything about every class and item in the game and the metagame. If you got to that point with programming you could earn really good money, maybe even enough to have a girlfriend.

About every language without switch/case construction.

Probably a stupid question, but I'm trying to learn some PHP.

I chose to learn by making a family website where I'll be putting up pictures from over the years, so everyone in the extended family can both see and upload their own pictures. Especially newly digitalised photos from way before smartphones and shit. Just for fun really.

Anyway. Basically my question is this: How do I, by a link or something similar, generate a custom page, where the link passes a value from my mysqli database?

I've only been learning for a few days. Any help is appreciated.

You guys good at databases? There's no database general so I thought I'd post here.

These things are seriously awesome. It's gotten to the point I'm using them as replacement for spreadsheets. Whenever I want to keep track of something over medium and long term, I make a database now.

Really small ones are so easy to use with SQLite. Really easy to access programatically. I think it should be the default solution to the "how do I write something to disk and load it later" problem. UTF-8 text is the second best solution; human readable but requires parsers and generators. Security exploits are often found in this user input handling layer. SQLite is ridiculously well-tested.

I seriously hate object-relational mappers now. The entire idea is just fucking retarded. In many companies I got to watch as teams of pajeets eviscerated perfectly good relational designs, as if they drove data requirements. It's the other way around; database drives the application design. If you have a database, protect it at all costs, especially from teams of Java/Ruby on Rails/.Net pajeets who think of everything as a class with attributes. Our DBAs were either fucking pushovers or management denied them the authority to do their fucking job

Seriously ORM a shit. An SQL abstraction layer is fine since it allows independence from the underlying database's specific features, but if you're abstracting away SQL, you're doing it R O N G

I have a burning question regarding databases actually.

I have three tables, where one has keys to the other two. What I want to do is this:

SELECT * FROM db_1 WHERE a='$v'
INNER JOIN db_2
ON db2.key = db_1.key
INNER JOIN db_3
ON db_3.key = db_1.key

But I can't do that, because the WHERE would need to go last. I'm being retarded I'm sure.

Basically I have a certain record, which has an ID, and I want to access that record, using WHERE on its ID, but in the same query I want to access values contained in the two other tables. How do I do that..?

>>59943239

how is this kind of stuff programmed? i would like to implement something like pic related so that the user can explore a 3d node map, being able to create nodes or load diferent data sets. im trying with unity 3d at the moment, using an xml to load the nodes coordinates on the 3d space, how would you guys go about making such thing?

>>59943539
Rendering it is simple - each node is a sphere and each edge is a line. The hard part is spreading them out in a visually pleasing way. There are loads of papers on that subject, but the basic principle is to make each node repel each other node but make connected nodes attract each other. The keyword you're looking for is force-directed graph drawing.

This. You'll end up spending 99% of the time figuring out how to draw a triangle, then spheres and lines and eventually abstracting that to create a bunch of spheres and lines easily. You'll spend days figuring out how openGL works versus whacking out the visualization in a few hours in Unity.

Not sure if anyone from the thread yesterday is here, but I actually took the advice to stop learning Python and give c++ a try. So far i'm enjoying it a lot more. I'd already been reading a lot about how computers actually work, and c++ seems to reveal a lot that python obscures and does automatically for you. Even simple stuff like how when you create a variable, it has a value already from whatever memory address it accessed. A bit trickier maybe, but it's cool. Also I like the tutorials for c++ way more than the ones I'd used for Python.

audio visualizer has been on my mind for some time, but there's a shit ton of fucking stupid red tape that goes into updating a college owned website.

I really want to make a better automation system for music that plays when no dj's are on . rn we use wideorbit and they want you to buy some expensive ass software called musicmaster to make better unique daily playlists.

all our music is picked right now from alphabetical rotators that play songs in order. whihc leads to some songs being played more than others (i.e voewl rotators such as "Rock Rotator A' contain rock category songs that start with A, which there are a shit ton so rarely they all play)

Well, in that guys link Python 3s map actual does return an iterator to the mapped object.

How do I avoid choice anxiety when choosing to learn a new language? There are so many languages out there, no silver bullet, and a mass of dissenting opinion. Even though most things could be written in a handful of languages, there are zealots for everything.

It makes me ill to think about going down a road for a year just to find out it was the wrong choice and no one uses it.

I don't really consider myself to have strong language loyalty, although I do find some languages displeasing to work with, namely PHP.

Universities are really for teaching you how to study and learn more effectively, they are supposed to teach you the tools to do that. Unfortunately in the last 50 years or so they've turned into drone worker-producing mills. Hence why there's so many Java schools today, companies don't want to have to wait a week for you to pick up Java when they hire you, and they also don't want you (rightly) complaining that Java is garbage.

>>59946465
so? where does the university come in on that? weekly lab exercises? assignments? does that give you programming experience?

>>59946467
>Universities are really for teaching you how to study and learn more effectively, they are supposed to teach you the tools to do that.
that's correct.

>>59946432
how would that work? you expect normies to store the key in their cache and never clear it or something?

>>59946490
Programming experience comes from projects and assignments they give you. Most of the time the only guidelines given is what language to use and the end results. There is no step by step, it is sink or swim. If you don't know the language, you better learn it and complete the assignment.

>so? where does the university come in on that? weekly lab exercises? assignments? does that give you programming experience?
yeah, computer science is about more than just making programs though. the classes i've taken so far that stuck out to me as very useful were organization of programming languages, which was kind of a meta class about languages themselves where we did a bunch of different languages like prolog, and made a scheme interpreter in scheme which was wacky. operating systems was also pretty good, self obvious. theory of automata and linguistics was useful, lots of heavy hitting stuff in there. analysis of algorithms was very foundational. you can definitely learn the stuff yourself, i'm trying to teach myself assembly because my school doesn't even have a course on it, but if you just go to code academy and learn syntax you're wasting your time. i can rec you some good books if you want

>>59946501
>>59946534
The website would have your password (encrypted at signup using your public key) stored somewhere, and it would be emailed to you when you tell it you've forgotten your password, and you'd be able to decrypt it using your private key. That way, the website (and anybody with access to its database) would not be able to decrypt your password, but you would still be able to get it in an email reminder.

You don't keep your public-private key pair in cache, you keep it somewhere persistent.

You are expected to do a lot of self learning in colleges/universities. That is the part people struggle with. It is no longer structured like in high school or junior college. Suddenly people have a lot of free time (which they are supposed to use for self studying) and no idea what to do with it.

>where does the university come in on that?
A job board that involves more than dead end tester jobs and pretty much every self-taught "software engineers" and "senior software architects" I've met fucking sucks and are so crazy inflexible they fret over the minute you propose anything that's different from the usual OOP imperative bullshit.

Not to mention the crazy amount of code they paste, not understanding what the fuck they are seeing in their IDEs and working with self-learners is just a terrible terrible experience overall.

Where does college comes into play into making people less shit at everything, I don't know. Probably being forced to know the very basics, instead of jumping straight to java fart apps. I definitely know that self-learners should stick to sucking dick for a living instead of infecting my existence with their incompetence.

>>59946620
In theory you could sign and encrypt an entire password reminder email to be sent to you if you lose your password, and give that to the website at signup. That way it would just work with email clients that support PGP.

In the worst case you could decrypt the encrypted password sent to you using GPG on the command line.

I agree that anything automated would look stupid these days, we've trained people to complain about websites emailing you your password because it usually means they're storing your password in plaintext somewhere. Good luck trying to get most people to understand public key crypto, why the approach I'm suggesting is safe, and how to distinguish it from websites storing your password in plaintext and just lying about using crypto (especially since you can't know unless you're sure you never ever sent your plaintext password to the website - not even at signup).

>>59946581
I saw this in /sci/. Nice try.

>>59946424
>>59946490

Computer science and programming are not one in the same. Once you have mastered logical statements, loops/recursion, binary/hex, the common data structures (linked list, tree) and basic algorithms (sorting, searching, recursion v iteration, etc) you'll be at the level a normie is after 1 year of CS; and you'll be behind them in terms of math almost definitely.

If you want to work at a code mill, or be a middle class web dev then programming is fine. If you want to work in systems development, game programming or algorithm development you want to go the CS route.

>>59946467
this is simply not true, universities are good for teaching you things you wouldn't know to learn. And also forcing you to learn things at a steady pace and expanding upon basic knowledge. It's also a place where you get hands on experience.

i recognize you b/c you post here all the time. i never read a book on python, i just read the learn x in y page for it to get basic grips, googling the error code, and absorbing from code golfing online. the more languages you learn, the quicker they are to pick up. i'm not really fluent in any language desu, i'd need to google stuff if you told me to write a java program or something. idk about certifications dude i just know they exist and some are better than others. look into what certifications in IT are reputable and maybe get a 2 year / community college degree. just tell your granddad regular college isn't working out. more importantly for your depression make sure you have a friends group, maybe go to the gym and strike up a conversation with a guy while you're working in on the same squat rack. i just met friends in class. only really got 1 friend, mexican guy in my software engineering 2 class i go to mcdonalds with b/t classes. got a fat fwb tho. i stay sane, used to be depressed

books i rec:
1. structure and interpretation of computer programs <-- the point isn't to learn Scheme
2. http://learnyouahaskell.com/chapters <-- the point isn't to learn haskell
3. K&R <-- the point is partially to learn C b/c C is cool
4. The art of assembly language <-- the point isn't to learn assembly
5. Introduction to algorithms <-- don't read the whole thing, and don't even necessarily read it linearly. act like the chapters that say advanced don't exist

even if you're not a software developer, programming is very useful for scripting. you need to know how machines work and about their anatomy. i'd say these should get your bases covered on the software end of things, with assembly delving just a bit into hardware. maybe do a small bit of each book every day

It could be as simple as they generate a nonce, you sign (nonce, username) and send the signature back to them. You wouldn't even need a password, rendering this whole discussion about forgotten password emails moot.

If you really want to use passwords, I think you could sign (nonce, username, hash(nonce, encrypted password)) and they could verify it. (The encrypted password would already be stored in the website database, along with your username and public key.)

And I don't think I'd have stayed in a program that didn't teach at least a little of how the underlying hardware works.

But you are right, it's mostly a shit ton of math + implementing said in CS with programming classes teaching the code monkey stuff. The fun/interesting stuff doesn't happen until after your 4 years are up; but i don't know that i'd recommend quitting after your BS because there's a ton of pajeet with a BS in CS.

Yeah there's also my university's library which provides free ebook access. Got plenty of time to read it over my free time. I go to the gym but don't really have a friends group.

>physics
what are you on about? unless you mean computer networks and stuff with sine waves? i'm just finishing a course on that now. we never had to do a fourier analysis or something by hand, closest to that was telling what the bandwidth of a composite signal would be from the equations etc.

>>59946801
at most schools, getting a bachelors of arts in CS would be harder than getting a Bachelors of science, since CS courses are interwound around the requirements for a BS and not for a BA so youd have to technically get both

you don't need to go partying with people on the weekend, that's only that one type of person that does that. just striking up a conversation with some guys in class asking about an assignment can lead to a friendship if you keep up the conversation

sadly for pajeet computer programmer was recently removed from the list of professions for the h1b program

>just striking up a conversation with some guys in class asking about an assignment can lead to a friendship if you keep up the conversation
but that's just being classmates or acquaintances.

i have quite a few i know that way, but i don't consider them friends and neither do they.

>>59946801
Shit ton of math is also a huge overstatement. The physics I had were mostly part of the curriculum which was completely tangential to the rest of my career, I only ever needed the very basics for doing computer graphics, pretty much just Hooke's Law for a cloth simulation and calculating normal vectors for pretty lighting.

You also need a bunch of statistics for simulation and markov chains and stochastic models and all that fun stuff but, again, unless you are on a postgrad course, you ain't doing much of that for most of your career.

And I don't know, maybe quantitative methods for optimization problems, but you can hardly call that "math heavy"

I mean, there's more maths in there than a fucking arts degree, that's for sure. But I'm not comfortable comparing myself to a bonafide engineer, I tell you what.

>>59946881
talk to them more and become closer to them then. you're not labelled with a big sign over your head telling other people not to be friends with you, you probably just keep yourself distant from other people because you think it's less stressful to not be involved with anyone

that's true

i ended up brushing away offers to study together and shit. not to mention by the second term, a robot had more friends in the department for some reason

>i ended up brushing away offers to study together and shit.
there you go, simple as that. and next time you overhear a group of people saying they're doing a study group now you have to put yourself out there and say "hey mind if i join? i'm having trouble too" because you're in the negative. it's always like that, things are handed to you at first and you turn it down, not so easy the second time. after that you have to pursue it yourself

fellow shitter state university bro reporting in. i'm in the honors program so i think that counts for something at least, builds up the name a little. if it's a physical university and they're accredited it can only be worth so little

>Dynamic types
Why is this a bad thing? Ruby was designed around a model of message passing, like Smalltalk. It has meta-programming features that take full advantage of this. Ruby would be a pretty boring language if it were statically typed.

>Adding end to all your blocks
You mean like Ada and Lua do? It's not that terrible, mate. Which would you prefer instead -- braces, lispy syntax, or the forced indentation of code?

They told me it was easier than Calc I, fucking liars

>>59947237
I don't like Lua either. Never used Ada.

I prefer any of the other three (braces, lispy syntax, forced indentation) over what Ruby and Lua do.

Dynamic types aren't my thing. Advanced static type systems remove the need for a lot of boilerplate. I'm also a fan of the compiler yelling at me if I make dumb mistakes.

Using 4chan as a distraction from learning C.

Does Android dev still suck ass? Apple redeemed itself with Swift (which is actually a pretty fun language to use) but the Java environment on Android is just terrible.
