you forgot VIM

If you want to learn the ins and out of mobile hybrid development John M Wargo books are one of the most highly rated, so if you need the 2017 edition of​ his book for the latest cordova 4 titled,
Apache Cordova 4 programming and the companion Apache API cookbook, holla at me.
This books currently go for 25-30 dollars on Amazon, but i just might cut you a deal

NL isnt serious about programmers, else it should have solved issues with embedding code, all this while, and spambot sef, go dey act up atimes when posting code

There is no *Best*, just choose one of the popular ones, Perl, Pythn, Ruby, Node, PHP, GO. and get on with it

Actually tboth code would give you varying results depending on compiler and architecture, it has to do with stuff C terms
1. Sequence points
2. Order of evaluation

the explanation is long and twisted but please see this stack overflow post...
http://stackoverflow.com/questions/4176328/undefined-behavior-and-sequence-points..

U mixed up your expectations tho;
Then again its the second code that should give 3 and the first 43, heres y..
Second Code:
j = i--- -2;

would evaluate as or should in most cases, aslo it would be different on C99 and C11 compilers

 j = i-- -(-2);

the i has a post increment so remains 1, for the duration of that assignment
-(-2) yields +2

so i +2 yields 3

First Code:
If it yeilds 43, then the post increment wast performed first (as i noted such statements would yield erroneous/undefined behavior).

Generally avoid stuff like this, and read the linked post thoroughly

Why is this in programming section

BlueMagnificent:
I politely disagree with you point.

If whatsapp guys where waiting until they could acquire a good number of servers and infrastructures then you and I know that there would be nothing like whatsapp today. Same goes for facebook and even google.

First bring the idea to life then worry about servers and other infrastructures later.

Well good point, i agree, wasn't saying its not possible starting such a platform in a minimal way, but then personally i wouldn't venture into such without the semi-assurance of some form of investment as time goes on, cuz at least venturing into such you'll do it with the mind of such a platform succeeding, which means at a point you'll need to scale - up!

AntiWailer:
Flesh and blood did not reveal this to you.

No the spirits did

Normally data with apostrophe, should be escaped \' before inserting into the DB, just use PDO::quote, or you could str_replace and do the escape ur self.

I sometimes use this on the data before inserting

trim(strip_tags(stripslashes(htmlentities($input_data, ENT_QUOTES, 'UTF-8'))));

pachman:
After something that occurred to users of whatsapp where whatsapp was literary said to be down. I observed one thing, the outburst of Nigerians just on a thread alone https://www.nairaland.com/3778205/whatsapp-down few minutes after the thread was created.
I am not a so good coder but there are Nigerians, expert coders on this forum that can build something as good as whatsapp.
People were stranded because their whatsapp was down as it was something quite important to them. We can change something also, you can build your own social media.. Nothing is too small, small beginnings lead to big endings.... Look at snapchat, whatsapp, facebook, instagram, allo, etc. Start with something!


Please mind my typos

The messenger app features of whatsapp arent exactly so much of a big deal to develop, u need to understand whatsapp runs on a complex server infrastructure to support billions of messages daily, so investment literally would be the challenge, you'll need several dedicated balanced/fail-over servers [i'm talking high-end, many-core/many-ram servers) to setup and a well written backend system (Whatsapp backend is mostly erlang btw), Running such an infrastructure requires solid investment, not impossible at all tho.

The whatsapp FB bought for about $19B, had a server count of several 100's, and collectively over a thousand processors +tera Bytes of Ram, and thats just a part of the big pictre

stealthtiger:
Wow. I'd be so happy if I'd be given the mandate.
Things really need to be corrected.
Nairaland programming section can also be a stackoverflow in it's own right

Comments and post feature's would need some minor updates, to realize that

Google OpenCV java tutorials, OpenCV is the gold standard when it comes to anything computer vision

Sillyness

Meet Linda a small, fast Active-record based ORM for PHP, designed to greatly ease and speed up database manipulations and access, i wrote it recently while working on a team project where we decided not to use too much frameworks and rolled up a lot of our own code, it has been successfully used on three more projects till date .

I HATE IT. I do Java and Python.

Lol good for you..
import java.myass




Python is cool tho

...Nice Signature

olamil34:
there programmers please state the reason why you hate php

Who says we hate it?

Well most likely cult related reprisal, we've all seen it happen too many times

Naziff:
like it's not working on the System
Yes it's the JDK

Whats the error its giving?

Seriously tho, I doubt if i have ever verified the checksum of a downloaded file, think the only time i did that is once when figuring out what checksums are/how they work, then never agaian

Naziff:
programmers in the house please where can i download java sdk8 file.
I've dowload both the 6 and 8 version from oracle for 64bits windows system, both the file are not supported. can anyone help with a better option.
thanks in advance.

how do you mean not supported, and i guess u are referring to the JDK

Lol for una trollers, but am in PHP and Database stuff

Craigston:
It is a totally new language. It's just not gaining traction. I'm not sure learning it will be a good investment, especially since it's targeting an already dominated niche.

Yep am sticking with 5 for now

Craigston:
Are you keeping tabs on Perl 6 development? I tried to but it seems the language won't see stronger support again. But the huge number of packages available in CPAN is still a blessing.

The whole thing is confusing i like some features of Perl 6, like the changes made to array-accessing/indexing, but mehn too many big changes to the language syntax its unnerving, Its almost like a totally new language

Assembly would be Taoism - It is so different from
other languages that many people don't
understand how can anyone use it to produce
anything useful. Its followers believe that it's the
true path to wisdom, but that wisdom is beyond
the grasp of most mortals.

Hmm hmm, been someone who has read books on Taoism, I totally concur here
