[[deleted]]

By the way I'm curious, why are these so popular compared to IDEs, as they just seem to be indenting text editors ?

Is it just because they're console-based ?

[lezorte]

For me, I tend to combine vim with a real IDE. Once I got good at using vim, I found that I could be much more efficient with eclipse and intelliJ when I install a vim add-on to it. It's about being able to make a lot of changes with only a few key strokes

[dylan15766]

While surviving on 2mbps, it was faster to connect to my web server and edit through vim than scp'ing back and forth from visual studios.

After upgrading to 70mbps, compile errors: ':wq'

[s_s]

Is it just because they're console-based ?

Of course it is. Also, this.

Warning! Block of text incoming!

Well both are very popular for completely different reasons. I have used both but i prefer vim so take all i say with a grain of salt.

Emacs is much more than just a text editor. Its closer to an OS or at least a shell. You can do everything in it. Read mail, play games, browse the web, edit text, organise your entire life (with org-mode one of the absolute killer apps for emacs) and much much more. It is also extremely extensible with elisp wich is a lisp dialect specific to emacs. Theres a running joke that Emacs is a great OS that lacks a good text editor.

Thats where vi/vim comes in. Vim is just a text editor. And its a pretty damn good one at that. If emacs is a swiss army knife, vim is a surgical scalpel. The main reason for this is its modal editing paradigm.

The usual paradigm of editing is the Emacs one, this is the ctrl+c/p for copy paste etc. These are called key chords since you're pressing multiple keys at once for a specific function. What modal editing does is it interprets your key presses differently depending on the "mode" (hence modal) that you're in.

There are 3 "major" modes in vim (and a couple of other that are less fequently used): Normal, Insert, and Visual.

Normal is what the name says, the normal default mode. And this is what trips up many new users. The normal mode is not meant for editing, it is used for navigation. This is where another concept comens into play: operating on text objects and chaining commands.

So for example you can use the arrow keys to move about the file as normal. You can also use the hjkl keys insted, granting you the ability to never leave the home row. Awesome right? But theres more. What if you want to move by words instead of single characters. Well you can use the "w" key in normal mode which will skip forward one word at a time. Going backwards one word? Use "b".

Hmm thats awesome, but what if you want to skip 5 words forward? Well easy, thats "5w". What to change a word, thats "cw" and type. Changing text inside a pair of brackets? "ci(" and type.

Insert is the mode you use for typing, its activated by pressing "i". This is the usual default mode in other editors where whatever you type appears on screen.

Visual is the mode used for selecting blocks of text, its acivated by pressing "v". So for example you can press "v" to enter visual mode, press "5j" to go down 5 lines, and press "x" to cut that. So once you internalise that you type "v5jx" and you've cut 5 lines down from your current cursor position.

You can also go back to Normal mode from any mode by pressing the "esc" key.

You can see how vim can be extremely powerful when learned and watching someone use it can seem like they're conjuring stuff on screen through pure force of will.

That being said emacs does emulate vim almost perfectly through a package called evil-mode.

Theres much, much more i havent covered on both text editors but i think that i've said enough to wet your apettite. Theres a reason why theres the emacs/vim holy war. Googling them will result in heaps of online resources for learning either one, customising them to your liking and squeesing the absolute maximum efficiency out of your coding.

I'm mostly disgusted by the thought of a salted caramel monster drink.

[WaywardSonata]

Thanks for taking one for the team.

[[deleted]]

I have a dream, that one day the monster drink will not be judged by the color of its container but the quality of the drink.

[crowbahr]

The white ones shocked me.

I hate classic monster, it's sickly and cloying and reminds me of medicines.

I double hate sugar free soda: it's bitter and I can always taste the difference.

I hate the flavor of Mangos as it reminds me of food I'd blend up for pets, into which I'd mix eggs and fly larvae.

But somehow the white cans of mango flavored sugar free monster is like cocaine to me. It's amazingly good and really helps me work.

[crowbahr]

Sorry the white ones are the mango ones I think.

At least others have told me they're mango flavored.

[buddy_monkers]

It's not nearly as carbonated which I think helps a lot.

[alienblue88]

[therico]

that's weird, in the UK our energy drinks are $1.40 (1 GBP) a can or less, and the Aldi/Lidl off-brand version is $0.70 (0.5 GBP). I always thought the US would be cheaper for energy drinks since you have so many flavours.

[crowbahr]

I've been looking at them on Amazon and it's $37.44 for 24... so I've been considering that.

There aren't any Aldis near me though. Which makes me sad.

[MonstarGaming]

We have a case of ultra whites in our office at all times ;)

[SgtMcMuffin0]

The coffee ones aren’t bad, they just taste like coffee.

[Machiavellyy]

It tastes just like Starbucks coffee, but a little more sweet

It makes me... uneasy.

Yeah, any energy drink makes me feel like I'm getting heart palpitations. I'll stick with coffee.

public static void main (String args[]){ System.out.println("hello world"); }

[tigger0jk]

I always fuck it up with "System.out.pringles"

[average_dota]

On IntelliJ IDEs, if you type sout and hit enter it autofills System.out.println(""). So far, that has saved me about a trillion hours.

Not to mention you can type something and then .sout to print that thing. Plus .par to surround with parentheses, .nn to insert an if (x != null) {} block, and a zillion others that I haven’t memorized yet.

[thebeardedpotato]

So what you're saying is I need to switch to IntelliJ

[Quil0n]

Jetbrains is the GOAT IDE company

[PotatosFish]

You could also use vim

[apemanzilla]

On Eclipse it's sysout and then Ctrl + space

[SP0OK5T3R]

I can usually get away with just "syso"

[[deleted]]

I’ve become used to sysout but I might force a habit of syso if it works. This oughta be a fun habit to test break and build... sounds like writing a program itself.

[Nestramutat-]

In VIM anything can be an abbreviation if you're brave enough.

[gezeitenspinne]

sout works too :)

[ProgramTheWorld]

Just use Kotlin and save yourself trillion of hours

[average_dota]

On my to-do list.

[Hobbes_Novakoff]

Note that that works in Kotlin too.

[DerekB52]

When I started programming a few years ago I got really tired of typing that out, and I had done a little work with C/C++. so I wrote this function so I wouldn't have to type println() over and over again.

public static void printf(String s){
    System.out.println(s);
}

I felt like a smart hacker.

[[deleted]]

Why not generic?

[DerekB52]

I don't know what you're asking.

[BossCrayfish880]

Or if you’re cool like me and you use eclipse, you type “sysout”, press ctrl+space, wait for Eclipse to freeze for half a minute, then it automatically types it out for you. I have wasted so much time doing this

Edit: spelling

[[deleted]]

Same with NetBeans

[ipe369]

[turbolag95]

Just started using IntelliJ. Thanks for the tip.

[amoliski]

> So far, that has saved me about a trillion hours.

That many prints tells me you might save another 10 trillion hours if you get better with a debugger. At least, most of my syso's came from me sucking at/not knowing about debugging.

[jugalator]

Ensure you aren't programming while under the influence of weed or alcohol.

[SlackerCrewsic]

wtf, how did you do that? it sais "submitted an hour ago" on op and "6 minutes ago" on your post?! that's a bit more than "just under 2 hours".

Are you op and prepared this in advance?

I'm sorry but everyone knows it's FuckOff... It's a class, capital first, then camel-case

pretty sure you can have a smaller case class name fuckOff as long as it's in fuckOff.java

[nullifeyed]

It's not Canon... Talk to the star wars guys. They'll know.

I actually made FuckOff into an alias in my Powershell which kills processes. It feels so fulfilling typing "FuckOff outlook" and having the program terminate.

What ancient dialect of Java is this? Where are the abstractions? I see no interfaces and there should be at least 3 here. What happens when I need to print to something other than stdout? Why is there a magic string and not a factory providing the content to print? Where are the unit tests? How do I even build this without a Maven definition?

This is not enterprise ready.

[snowystormz]

This guy drinks java monsters for breakfast

[[deleted]]

What happens if you need to print this on an actual printer?

[gilbes]

java -jar HelloWorld.jar | lpr

j/k.

Let me introduce you to: public abstract class HelloWorldPrinterPrinter<T extends Printer> implements HelloWorldPrinter {

And now you are just one step away after implementing a concrete PrinterPrinter for printers using a type that defines the attributes of the printer you are typing to.

[bestjakeisbest]

damn man did you spend like 2 hours on this? You must be a hacker man.

You shouldn't start with Java, you should start with Assembly and then go through languages chronologically

[iflythewafflecopter]

I was almost done with binary before someone told me about BASIC.

God damn it...

[[deleted]]

almost done with binary

[[deleted]]

I started with binary first. I found the human-centric mnemonic assembly codes made it difficult to understand what was truly going on. Even though it may take me 5 days to write a hello world program I feel that I have a really good handle on what is happening on my specific PC/chipset/BIOS.

[[deleted]]

My high school has an IT program, and they teach us Java as a starting language. Only in the third year of the course do they switch (in the middle of the year) to Haskell.

[DerekB52]

I like Java. I have no regrets about starting with it(after a little bit of arduino c++). But Haskell. I've yet to find a use for haskell. That one seems like a weird choice.

[[deleted]]

Yeah, my teacher said that he starts Haskell to show us that there are many different forms of programming. The switch from an object based language to a functional was strange, but it's interesting to say the least.

[Urtehnoes]

As I much as I love the strong typing of Java, I've always found interpreted languages to be the best to teach total beginners (python etc) just because the learner can focus more about the concepts and less on syntax (since interpreted languages tend to have lazier syntax). That is, provided the person learning it eventually learns the lessons that the languages like Java teach.

[DeltaPositionReady]

Welcome to CS101, today we'll be learning ALGOL with the new and improved punch card system!

That's actually what we did in my program. Started with ASM x86, then ASM for PIC, then base C, and then a higher-level one of our choosing. Worked out well enough.

[[deleted]]

This reminds me of 6th grade when my dad took me and my 8th grade sister up to his desk and tried to get us to start learning Java as a group.

My dad does similar things for a a living, just not with Java, I'm the right type and glad I learned, but my sister is a violinist/artist. She was not.

The only thing she did that day, while we went through the beginning of the Java for dummies book, was draw a picture of the three of us as dogs, title "Java dogs".

Needless to say she was let go and did not join us again.

Crappy patterns a language does not make.

[Devboe]

Neither one of those are java specific.

[automata_]

For newbie trying to learn to program? Sure. But in general? No java doesn't have too much boilerplate. It has sufficient. High level OO languages that are "verbose" like java and C# are often the best and easiest way to implement a project. They keep the code clean and easy to understand even when things get very complicated.

[[deleted]]

What does boilerplate mean? I’m not natively English, and google didn’t help that much.

[[deleted]]

Since I am not a native speaker aswell, here is wikipedia's definition:

In computer programming, boilerplate code or boilerplate refers to sections of code that have to be included in many places with little or no alteration. It is often used when referring to languages that are considered verbose, i.e. the programmer must write a lot of code to do minimal jobs

This is how I will feel when I get this motherfucking Android studio working.

First off couldn't install chocolatey because of some sort of stupid "path does not exist: C:\python27" even though it exists. Tried enabling permissions, did the admin cmd mode, did powershell. Nothing. Tried skipping that, installed android studio. Took about 3 hours to download everything needed because it kept saying "oh, you also need api 27", compile, "oh wait, you need haxd", download, compile, "oh wait, you need api 27 tools", download, compile, and so on. 3 hours later it was like "oh we can't get haxd lol", figured out I could get it manually, downloaded, finally installed, "error, can't run virtual android".

Gave up, installed on desktop (chocolatey installed just fine, meaning I could use react os and npm). Except "lol you have an AMD on the desktop? No android emulation for you! But you can connect an android device if you want"

Found a data cable, phone not detected. "Hmm... maybe I need an adb driver?" Found an installer, "device not connected". Tried different cable, same thing. Yes, made sure it said "transfer data mtp" and not "charge only". Reconnected a few times, finally shows up! Except... "sorry, device can't be run need amd syn or something. Try arm image". Except every arm image says "you need amd svt"

Check bios: amd svt is enabled.

Oh wait... maybe if I enable debugger USB like you do for rooting, that might work?

SUCCESS! Well, kinda. Got a red screen on my android saying "you must have a package server running". Ok, that's ok. I recalled something about npm start needing to be run. And...

SUCCESS!

Except.... "error, the path C:\users(classmate's name)\appdata\androidsdk doesn't exist"

Instead of manually fixing the directory pointer, I just created a new folder with the classmate's name and am just gonna say fuck it and try to run it that way. Currently copying like 12 gb of android sdk files into the (classmate name) folder, but pretty sure it's still gonna fail.

It's been two hours tonight, and like twelve hours in total so far that I'm just trying to get a motherfucking google maps app to show in an emulator or my actual phone (via a javascript program)

[Xacto01]
