This script has been in daily use since 07/13/05:

code:

# Modified to make send_all.pl taking command line parameters: host_name and AE_Title
#(i.e. Send_all.pl P035.01.1_ -h G3k3sys3 -D redactedG3k33SCP)
#
# Usage : send_all.pl [file prefix] => works as before
# 	: send_all.pl => works as before
# 	: send_all.pl [file prefix] [-h HostName] [-D AE_Title] => Take host_name and AE_Title from command line and
#								send the files with an specified prefix
# 	: send_all.pl [-h HostName] [-D AE_Title] => Take host_name and AE_Title from command line and send all files
#							from current folder
#	: send_all.pl [file prefix] [-D AE_Title] [-h HostName]
# 	: send_all.pl [-D AE_Title] [-h HostName]

...and here's how that's implemented

code:

elsif ( @ARGV > 0  )
	{
		$send_all_flag = 0;
		if( $ARGV[0] =~ /-h|-D/ )
		{
			$filename = "";
			$send_all_flag = 1;
		}
		$i =0;
		$line = "";
		while ( $i < @ARGV )
		{
			$line = $line . " " . $ARGV[$i];
			$i++;
		}
		$hTemp = "";
		$calledTemp = "";
		if( $line =~ /-h(.*?)-D/ )
		{
			( $hTemp ) = ( $line =~ /-h(.*?)-D/ );
			if( $line =~ /-D(.*)/ )
			{
				( $calledTemp ) = ( $line =~ /-D(.*)/ );
				$hTemp =~ s/^\s+//;			#strip leading space
				$calledTemp =~ s/^\s+//;	#strip leading space
				$host=$hTemp;

				else
				{

				}
			}
			else
			{
				print "No -h or -D specified in command line parameters\n";
			}
		}

		{
			send_all_files();
			exit;
		}

Ruby gives you loads of rope to do fancy poo poo with metaprogramming. When I start seeing myself write stuff like "string".singularize.classify.constantize.send("another_string") I realise that I'm probably using that rope to hang myself, and should probably stop

I've never even so much as looked at Ruby before but I looked up what that does and wow:

quote:

Constantize tries to find a declared constant with the name specified in the string. It raises a NameError when the name is not in CamelCase or is not initialized.

Examples

"Module".constantize #=> Module
"Class".constantize #=> Class

quote:

classify(table_name)

Create a class name from a table name like Rails does for table names to models. Note that this returns a string and not a Class. (To convert to an actual class follow classify with constantize.)

Examples

"egg_and_hams".classify #=> "EggAndHam"
"post".classify #=> "Post"

[ show source ]

quote:

singularize(word)

The reverse of pluralize, returns the singular form of a word in a string.

Examples

"posts".singularize #=> "post"
"octopi".singularize #=> "octopus"
"sheep".singluarize #=> "sheep"
"word".singluarize #=> "word"
"the blue mailmen".singularize #=> "the blue mailman"
"CamelOctopi".singularize #=> "CamelOctopus"

I'm going to have to look into this Ruby thing in the future, I've been looking at c++ COM objects too long to wrap my mind around this stuff.

Where's the horror? I write OO in C all the time and while I often wish I were doing it in a language that made it easier, it remains a great way to organize and think about your code. Anyone who has read or written code that does COM in C has seen stuff that looks practically identical to this. It may seem silly to you but Chen's justifications are valid ones, especially when you consider the constraints of the early 90s.

Yeah but we're in 2011 and you still need to deal with all this COM bullshit to write a shell extension. It hasn't gotten any better since the late 90's.

It's mostly a "what the gently caress would you be doing with 32k threads" issue. A semaphore limits the number of threads that can access a resource or resource pool concurrently. 32k is an enormous number of threads - on my machine, explorer.exe is using 32 threads (you can check in task manager what apps are using how many threads.)

We had a guy that would do this regularly, and it frustrated every other person on the team to the point where no one even spoke to him anymore. Almost everything he committed wouldn't compile because he had things checked out for weeks, and it was on everyone else to make their code work with his broken merges.

The worst thing was, he kept a checklist of features he'd added, and passed that along to the Division Manager (above our team lead and project managers), and get patted on the back for it. If we reverted his changes, the Div. Manager would check logs and see that one of the other guys had reverted it, and the conversation would go:
: ~~REDACTED~~ added this feature and the system says you deleted it, why are you deleting other peoples work. I told the client this feature was complete.
: His commits didn't work, he improperly merged without testing. It broke the entire project.
: IT'S NOT ~~REDACTED~~'s JOB TO MAKE EVERYONE ELSES CODE WORK, EVERYONE HAS TO TAKE RESPONSIBILITY.

Instead of having to deal with lovely upper-management and having to fix all his crap, we (dickishly, I admit) kept track of what features he was working on and as a group beat him to almost every single one of them for close to a month, so when he went to commit his changes the team lead rejected them for needless duplication.

We all had a good laugh until we found out he was still filling out his checklist and passing it along to the division manager and getting props for his good work, so I guess the moral of the story is be a bad developer and get mad props, or something.

You aren't being clever enough. Break his stuff when it's merged in and modify commit history (exercise left to reader) so the bugs come in blaming him. Complain behind his back to upper management - use phrases like "his brain doesn't work right". Crack jokes. Set other managers against him.

Why I hate strings in c++ on win32 platform...

// Convert from string to ULONGLONG.

// VT_UI8 is not supported on W2K.
// So we can't use a variant to do the conversion

// There is a _ui64tow_s and a _wtoi64, but no _wtoui64,
// so we have to use _wtoi64 and convert the string to a LONGLONG
// and put that in our ULONGLONG.
// If the string is greater then _I64_MAX, then _wtoi64 returns _I64_MAX.
// But that should be plenty big for all practical purposes.
//
// If _wtoi64 encounters an error it will set the value to 0.
// This would only happen if the XML element contains a bad string,
// in which case 0 is appropriate.
// If the string has a number in the front, it will take that number
// "123 bad string" returns 123.
//
// _I64_MAX == 9,223,372,036,854,775,807

That is not how databases work. You could model it in three different tables: forums, threads and posts. A post would have a foreign key column to a thread, and a thread would have a foreign key column to a forum.

Maybe part of it was I wasn't able to get a feel for the goals and stuff of the language right away, but that's not really an excuse for me posting retarded poo poo, that's just me not taking the time to comprehend something and then spouting poo poo off about ideas that I only half understood.

I think your core argument was "this language looks like C++, Perl and LISP hosed and C++ drank throughout the pregnancy."

Why the hell does Twitter need constants for both years and solar years?

edit: Skyrim's PC version was compiled without any compiler optimizations. A modder rewrote the x87 code to SSE2 and inlined a bunch of getters and got a boost of ~40% performance. Bethesda has now released a patch that, among other things, "Improved compiler optimization settings"

These are the same chucklefucks who evidently didn't understand what heap fragmentation was on release so you could put a performance counter on virtual bytes and just count the minutes until it hit 2 gb and then Skyrim would crash for some mysterious reason.

How much you want to bet that in this patch, they turned on full optimization instead of doing profiling and setting optimization pragmas in the methods that would benefit the most?

I ditched jQuery and wrote my own wrappers for common functions, and a builder to target specific contexts (per page scripting, or mobile device optimised scripts). jQuery, at best, is a rapid prototyping tool. It's not bullet-proof by any means.

There's lots of ways people get random numbers wrong and many of them aren't related to the algorithm used by the PRNG. It's still possible to get skewed probabilities even with a generator like Mersenne Twister. For example if a PRNG or even a genuine entropy source produced an output from 0-16, if you restricted the output modulo 15, the number 0 would be twice as likely to show up as all the other numbers.

One really dumbass thing I did one time was calling 'create new rand()' in the constructor for an object... The results were very much not random.

These blocks occur twice in a switch statement from adjacent cases where its identical. The full paste is: http://pastebin.com/ArbTafTP

For added fun: the files themselves are duplicated completely for two different projects in the solution. Or rather, they should be the same files, but comparing diffs seems to imply that one was updated when the other wasn't. I suppose its almost not fair mocking students, but the person who wrote this is a CS senior.

It isn't ordinarily that bad - you're showing an example dealing with nested transactions and try/catch at the same time, and frankly you're probably better off structuring the logic of your stored procs so you don't have to deal with nested transactions if you're at the point where you feel like they are necessary for some reason.

Even worse are the ways of simulating the processes of passing documents from person to person with a growing pile of notes stuck to the front. Excel is often used for this. Where MY GF works there is a person who's job is to take forms and turn a list of checkboxes into a binary representation and write it on the form so someone else can type it into a spreadsheet. You see, there's only one copy of the spreadsheet on a shared drive so only one person can edit it at a time. Periodically the spreadsheet is recreated and the previous one sent on to the next stage of the process.

While it is an excellent example of how to deal with contention using the single writer paradigm, it hurts to think of people doing it by hand.

I bet if you talk to the people at your GF's company, they'd look at you like you had two heads if you started talking about Google docs.

We moved over from Lotus Notes 6.5.1 to gmail... earlier this year. Lotus Notes was configured so that it was impossible to index your in-box (seriously) and that functionality was locked down by an administrator, so it took like 15 minutes to do a full text search of an inbox.

I don't know C++ at all, what's the horror?

The code only looks like it works. The functions are returning pointers that reference local variables - when a function goes out of scope, we stop tracking its local variables, and the memory used is on its own. You have no way of knowing if/when this memory is going to get munged later, the behavior is undefined and totally up to the system itself. This can lead to very hard to troubleshoot bugs - the compiler should warn you if you have warnings enabled about doing this.

But honestly, it's probably stupider that there is no explanation on the page about the use case for making a function return a pointer! Why bother telling how if the user doesn't know why he would want to do something?

Regardless of what is being used for HFT trading, the EOD accounting is still done with systems that track every last fraction of a cent actually made/lost so it won't really be that much.

a bigger wtf moment I ever in commercial development had involved sorting a list of points in a class where x/y/z coordinates were stored as doubles. I wrote an algorithm that would sort by x coordinate, then y coordinate, then z coordinate... I got very, very weird results.

Sure, but the solution to the problem isn't "gently caress it, let's make it as hard as possible to replicate", it's to make the code open.

TBH that actually isn't the hard part - people have problems in the scientific community even if you give them the source code. Just making sure all the libraries/etc that you could have linked against are present and that your build environment is reproducible is pretty tough when you don't test how easy it is to replicate your build environment (and you don't really know what you're doing).

E: Probably the wrong thread for this. Visual Studio is terrible anyways.

VVV : tl;dr There's some weird quirk that will make the runtime crash violently (complete with call-stack corruption!) if it calls a method declared virtual within a C++ template. I've got no idea what causes it but I spent a good 4 hours today debugging what I thought was a memory corruption issue. I thought it was the original coder's fault (and was going to complain about it) but the code compiles and runs fine via g++ so I've got no idea.

That's a sign you need to start playing with your project compiler settings - are you using COMDAT folding or other optimizations?

I'm going to go on a rant for a second just because. A lot of people look at projects like boost and, before looking at the implementation, say "wow, this is some incredible stuff." Then, when they look at the implementation they throw a fit because in order to do that amazing stuff, you need to write some scary code, frequently using the preprocessor and/or templates in ways that the average programmer does not.

Another good example is the code for the std::vector class itself, which gets my vote for the most difficult to read widely-used class ever.

I want to thank everyone in this thread for giving me the push I needed to force all my applications to use encrypted passwords instead of plain text bullshit sitting in the database. I hated doing it that way from the start, but everyone insisted that they needed to be able to read the passwords in plain text so that they could provide them to users if they called in. At the time, it was easier to just do what the customers wanted and give them plain text passwords, but today I'd had enough. I decided gently caress them, I'm not being blamed for this poo poo getting compromised at some point and thousands of users passwords being out in the wild.

Also, I've always been embarrassed to go back even a couple years and look at the crazy poo poo I wrote - now I'm looking at things as I write them and thinking "what the gently caress is wrong with you? There's a better way to do this." and I credit this thread for shaming me into being a better person. Thanks again everyone, I really appreciate it.

You're not supposed to store encrypted passwords, that is only a little better than storing them in plaintext. Use a one-way hash function.

What one-way hash function would you recommend?

perhaps i meant cryptographic when i said one way. SHA-256 hasn't been compromised, may as well go with that. Compute the hash based on the concatenation of salt (possibly time when password was entered + arbitrary string) + user password. That way no one knows the password and they can't plug your database into freerainbowtables.com.

No. Use something like bcrypt or scrypt that's designed to be slow to calculate, to slow down brute-force attacks.

Ugg, I googled this and found http://hashcat.net/oclhashcat-plus

So yep, I am embarrassingly wrong about SHA-256.

code:

function b64utob64(s) {
    if (s.length % 3 == 1) s = s + "==";
    if (s.length % 3 == 2) s = s + "=";
    s = s.replace(/-/g, "+");
    s = s.replace(/_/g, "/");
    return s;
}

Missed it by that much!

I know, whenver I see testAndSet used I always think it's dying to be broken up into two separate functions.

Amateur. TestAndSet should be three functions.
