Three Cool Things About D - The Case for the D Programing Language

[gbrlgrct]

Just bought the book. I am very optimistic about D.

[jgilb100]

the D programming language trumps Go at pretty much every aspect, even compilation times

[ferquo]

this code may be correct, but its way too complicated.

C# and Java are the best:D!

[Magnetohydrodynamics]

@ferquo Your opinion may be valuable but your statement is biased.

Learning a new language makes you a better programmer, 100% guaranteed.

[letMeSayThatInIrish]

The answer to the last question should have been: "Oh, I'm so sorry, I have no more books left!" 

[jmac217x]

can't stand this guys accent.

[SaschaHeylik]

Typo in the title :P Programming with 2 m, Google :D

[Synergy9k]

I know which language I'm going to learn next... :D

[slowkvant]

D is some good stuff!

[FlameHue]

Today I read a section on mixins in chapter 3 of The D Programming Language and my jaw hit the floor. If you are a C++ programmer, you definitely need to try D.

[phixxx]

this is an interesting presentation, but this guy might be the most annoying presenter ever-- why is he compelled to ask everything as a question before making a statement? "foo is bar. what does bar mean?" pause for five seconds. somebody gives half-correct answer. presenter gives correct definition. repeat.

[FearlessLT]

I wish php was client-side + server-side, that'd be a powerful programming language with very simple code.

[Borbuster]

Wouldn't the C hello world return 255 on failure rather than 127?

[enbiscuits]

hey...this dude is romanian...gogo dude xD

[TheKMKY]

18:37 I'm sorry Andrei but if you present incorrectly written program (incorrectly in the sense that it doesn't have return statement) and your args are based on this program you are just plain wrong. Add there return statement + try,catch and this program will behave correctly.

[vinkhe]

@TheKMKY "incorrectly in the sense that it doesn't have return statement"

A return statement is not required in C++. Even Stroustrup writes Hello World this way.

[TheKMKY]

@vinkhe Return statement IS REQUIRED. Check  ISO standard for C++03

[antred11]

@TheKMKY

Excerpt from chapter "3.6.1 Main function" of the C++ standard:

"A return statement in main has the effect of leaving the main function (destroying any objects with automatic

storage duration) and calling exit with the return value as the argument. If control reaches the end

of main without encountering a return statement, the effect is that of executing

return 0;"

[armd86]

TALK TO MEEEE!

[FetrovskyGoogle]

"It's the fastest language to compile of all that they know"... or something like that. Do they know about Go?

[TheCyberShadow]

@FetrovskyGoogle Yes, it compiles faster than Go too, by a huge margin. Obviously Andrei didn't want to say that straight in the face of a room full of Google employees :)

[TheCyberShadow]

@FetrovskyGoogle At 1:02:05 Andrei says that D compiles 4.5 times faster than Go.

[FetrovskyGoogle]

@TheCyberShadow Thank you, I actually heard it, but it was long after I posted my comment :)... it's ridiculous how long it takes to build a C++ or a Java project.

[yudlejoza]

the D and Go people should pool their efforts, merge the two and call it 'The GoD Programming Language'

[Ginto8]

@yudlejoza D and Go are very different. D is based on C++, and Go is based on C. D is intended to be C++ with better OOP. Go is intended to be C with useful, builtin concurrency. And that's just the simple explanation =P

[FetrovskyGoogle]

@yudlejoza *Very* good one!

[slavewholave]

@yudlejoza hahahah!

[ergius1988]

@yudlejoza it sounds like exactly what it would look like :-)

[Magnetohydrodynamics]

@yudlejoza Sorry, that title is owned by LIST.

[Magnetohydrodynamics]

@Magnetohydrodynamics Fuck, LISP! I MEANT LISP.

[QSerpent]

I think if we are comparing D's correctness to C's correctness it is only fair to use C99 (which is, what, 11 years old?) and not more archaic versions :) The point about printf's failures not being reported is valid, but C hasn't returned a random value from main() in more than a decade.

[rtsownage]

42:20 PROFIT!

[SatansSpatula]

Love the douchebag at 13:16 who can't listen (source, not headers) and has to prove himself right. It must really suck to work at Google, dealing with alpha-geeks like this all day.

[isx2007]

@SatansSpatula they create things like wave :p

[jsd1982]

@SatansSpatula Headers are source. It was a fair answer to a very open-ended question.

[mmtrebuchet]

@SatansSpatula I think the guy at 13:16 *really* wanted that book! =)

[QSerpent]

You are wrong about the return value of "main" in your C example - if main() has no explicit "return" statement then the value returned to the environment (in a hosted implementation) is *not* 13 (or something that happens to be in the right register), but is in fact 0 by definition. See C99 section 5.1.2.2.3p1.

[jbarbuc]

@QSerpent That is true if your compiler is a C99 compiler. My default gcc produces Andrei's result, but add -std=c99 and yours is correct.

[asdfwqtw]

@QSerpent

Was this defined for older versions of C though? I think the point was meant to be illustrative rather than literal.

[a1mint]

God-DAMNIT already ! Again with the aaahhh, uuhhhmm, uhmm, aaammm, uuuuuuu, aaaa....

What the FUCK is it with this goddamn AAAAAANNNAA, AAAA, taaahhuuuuu, uuhh, i have thisuuuu, and this bookaaahhhuuummm, sooaaa, aaahhmm, alright aaamm, aaamm, i'm sure aammm that many of you ammmmm, aahh first off, aahmmm other languages, so amm, is ammm, that aaahh, ammm, and that's compiled uhm.

[a1mint]

Also, Python most DEFINITELY is *NOT* a "beautiful language".

[jcao219]

@a1mint I would disagree. You probably have never gotten familiar with Python before.

[mkdbl]

@a1mint That's because he's not a public speaker, but a freaking amazing programmer.

[zaheu]

@a1mint I agree about the uuhms and aahms, particularly during the first 25 minutes. I was very nervous!

[EXetoC]

@zaheu That's perfectly understandable, so ignore people like him :-) Thank you for your efforts on D.

[supergopi]

@a1mint

What a dumb arrogant person you are a1mint !?

I fully appreciate the talker for talking in his non-native tongue

to room full geeks in google ! He even shows a good sense of humor !

[a1mint]

@supergopi I feel kinda silly going overboard. I got very annoyed. I like watching programming videos, but I felt it got sabotaged and made unwatchable by too much uhming, so I got disappointed.

I do appreciate someone trying though.

[coreboy]

Everything went better than expected.

[ewigkase1]

how many programing languages is there wtf!

[InXLsisDeo]

@ewigkase1

Too many certainly, and a few of them are interesting to study. D is one of the best kids on the block right now and probably the best contender as a successor to C++, although it's already a "big" language in terms of features. It doesn't have the conciseness of Google Go (which seems suitable for embedded devices to me), but it's at least as powerful as C++ and more sound on most areas.

[llothar68]

@InXLsisDeo

The large amout of D features was why i haven't choosen it. Maybe with Version 2 they stop language features for a decade and optimize the tool chain.

[FloppyFormatFrenzy]

@ewigkase1 Hundreds if not thousands.

[blenderpanzi]

Does D support closures? If yes can you execute a closure in another thread as from which the bound variables are coming from? (I guess not.)

[dsimcha]

@blenderpanzi : D2 (the current version of the language) does support closures, and they can be executed from another thread. I actually used this property to implement a parallel foreach loop in a parallelism library I wrote.

[jcao219]

@blenderpanzi yes

[llothar68]

@blenderpanzi

Why should execution of a closure outside the thread be a problem.

For a closure you (or the compiler) has to break the variables from the stack anyway.

I implemented something like this for Eiffel myself, wasn't difficult at all.

[blenderpanzi]

@llothar68 Hm I don't remember why I asked that. Maybe I got something mixed up. Was it D that isolates the memory of threads so communication between them only can happen over certain channels? Via closures it would be possible to access things allocated and possibly still used in another thread -> concurrency.

[llothar68]

@blenderpanzi

No D can use shared all memory. Maybe you mean Erlang?

[blenderpanzi]

@llothar68 Jep I think thats it.
