@JeremyDicaire The question was... about a guy who was very frustrated at getting syntax errors and bashing his head on a table from time and wanted to rant about it (and get sympathy?). Not a good question, certainly not the right place.

user55340

The suggestion of migrating it to TW.SE was more a joke because it wouldn't be the right place there either - and they'd be very unhappy with us if we did it.

@MichaelT but they are doing it to you no? lol

@MichaelT get a debugger that tells you where you have a syntax error, thats it.. or stop programming

user55340

Btw, favorite declined flag message: "declined - Server Fault would burn us to the ground if we migrated this."

Q: How your team manage shared password/key

It maybe a shared SSH private key, it maybe be a online password to some web site. In term of security & convenient, and support fine grained permission settings, e.g. developers role, testers role, devops role. Any suggestion for this task?

Its either that, or a cat was playing with the shift key while they were typing.

@MichaelT I can just picture my cat laying next to the keyboard while I type, just pawing the shift key because he's not being paid attention to

@MichaelT I like that

I noticed that someone stared one of my sentences... wt*

@WorldEngineer that migrated perl question is getting some comments on SO, and the user has an account there... so it may stick.

what is good about known-bad audits, what is bad about known-good audits...

A: Post I voted down and close is shown to me as known good audit?

In the absence of an authoritative explanation, I'll try to reconstruct the reasoning that led to audit I observed. I assume that ways to justify the failure for known good and bad audits when these contradict original voting of reviewer "mirror" each other. Reviewer who fails "known bad" audit...

user20683

turns out that $20 solves most of my programming issues

user20683

I feel dumb now

20 bucks?

beer?

user20683

@JeremyDicaire OS X Lion

11:11 PM

@gnat great answer!

user20683

see I'm on an old Macbook

@WorldEngineer I like my idea more :)

user20683

most software that I need to be fairly current only runs on OS X Lion or better

user20683

and Lion is the best I can run on this thing

user20683

it also means that I can finally get Windows 8 to dual boot properly (happiness)

11:12 PM

I once bribed (pizza) some friends back in college to help me debug some code that I had written for my job (sysadmin at social science). I brought the printouts of the code with me. Go there, ordered pizza... pulled out the code. It was sendmail rulesets. They quickly decided to not accept the free pizza and split the bill evenly.

user55340

Example code:

user55340

S4
R$* <@>                 $@                          handle <> and list:;
R$* < @ $+ . > $*       $1 < @ $2 > $3
R$* < @ *LOCAL* > $*    $1 < @ $j > $2
R$* < $+ > $*           $1 $2 $3                    defocus
R@ $+ : @ $+ : $+       @ $1 , @ $2 : $3             canonical
R@ $*                   $@ @ $1                     ... and exit
R$+ % $=w @ $=w         $1 @ $j                     u%host@host => u@host

user20683

@MichaelT That doesn't look so bad but I did put my brain through Automata

user55340

And that's just one "subroutine"

@JeremyDicaire glad you like it. Been feeling the difference between these kinds audits for quite a long (complaints against known good were just so much more frequent and louder at MSO), but couldn't catch what may cause that. Looked symmetric all the way, until I figured deleted part

Given that in order to be deleted, post has to go through quite stringent process, this would make a much more reliable selection than that based solely on close/down votes.

Actually, if "known bad" items are selected from posts deleted by moderators / 10K users, one can even argue that these audits passed through human verification before being presented to reviewer. If this is the case, it would be very important to take into account that selection of "known good" audits doesn't even come close to anything like that.

11:15 PM

@MichaelT I give up

user55340

(this chat room also significantly dabbles in MSO (Meta.StackOverflow) - outside of the MSO rooms, I'd hazard a guess that we've got the highest MSO activity of any other chat room)

user55340

@JeremyDicaire It converts some formats of email addresses to 'user@host' - but that, thats what they all do. Just one of rather obscure and terse syntax.

@MichaelT n00b... okay i got it now...

but there is better way to do it

or more human readable way

user55340

R$* <@> $@ is a rule (R) that converts some characters and stuff inside a <> into the stuff inside the <>.

user55340

@JeremyDicaire Nope... not really... and certainly not at the time.

11:18 PM

regex

but its slower

user55340

These are regexes.

user55340

The string is tokenized and the tokens are parsed.

user55340

The thing is you need to make sure you're handling the mail correctly.

well, my last php regex function wasnt like that lol

user55340

Some systems weren't on the network at the time... but connected to others that are. So you've got things like user%host_not_on_net@host_on_network

user20683

11:19 PM

Ecosystem when @MichaelT was in college C, C++, Perl, Java, and Visual Basic for the most part if I'm not mistaken. Maybe Smalltalk, Fortran, COBOL, ADA, and Pascal?

user55340

where it would first get delivered to the host on the network, and then it had to reparse the email address to the one that wasn't on the network.

user20683

Java was the new newness at the time

A: Is reputation the currency of Stackoverflow?

I'm still pretty new here, but here's my take on the question: Reputation motivates me to answer thoroughly and correctly. I used to be a regular at the W3Schools Forum. It was very common for wrong answers to be posted, and sometimes no one would notice. I was well regarded there, but sometimes...

Cobol, i dont know why but I always had a little crush for that language

user55340

No VB. Java wasn't around until I was a senior. C++'s first class was fought when I was a sophomore.

user55340

11:20 PM

I didn't go into the Business/CS classes, so didn't touch COBOL. I did have a class in fortran though.

user55340

(and that was F70, not F90)

user20683

I'm sorry

user20683

F90 is actually nice

user20683

has lowercase and everything

user55340

Or was it F77... F7 something.

user20683

11:21 PM

user20683

it's the infamous one

11:22 PM

Occasionally ran f2c on the code to read the C to make sure I did it right.

user55340

f2c is the name of a program to convert Fortran 77 to C code, developed at Bell Laboratories. The standalone f2c program was based on the core of the first complete Fortran 77 compiler to be implemented, the "f77" program by Feldman and Weinberger. Because the f77 compiler was itself written in C and relied on a C compiler back end to complete its final compilation step, it and its derivatives like f2c were much more portable than compilers generating machine code directly. The f2c program was released as free software (open-source software) and subsequently became one of the most comm...

user55340

I think that Qmail was starting to show up when I got out... though not sure about that.

user20683

@MichaelT I got to touch one of those in my PLC class

user55340

There are some really neat things that sendmail can do - and the bit that I was working on. All the profs had their own unix machines with distinct host names. So make sure that when they sent mail the email went out as user@socsci.wisc.edu rather than user@machine.socsci.wisc.edu

user20683

an actual program on actual punchcards by Dr. King who wrote C Programming: A Modern Approach.

11:23 PM

I bet you too have a lot of grey hair... sorry.. wisdom :)

my programming teacher at college told us about punchcard :O

user55340

However, when mail was inbound, it needed to get rewritten and delivered to their own machine. So that user@socsci.wisc.edu was then resent to user@machine.socsci.wisc.edu

user55340

Unless the mail was to be sent to one of the VMS users... and we had a list of those in some config file. In that case it was user%vms@gateway.socsci.wisc.edu

user55340

@JeremyDicaire never had to use it, though understanding the punch card made it easier to write the code because you understood why it was that way.

@MichaelT cool way of learning something I think

user55340

My father told of the joys of dropping a deck (of punch cards) and having to put them back in order. You typically used columns 72-80 for the line number, and also drew a line across the punch cards with a sharpie diagonally - so that you could put them about in the right order by sight.

user55340

11:27 PM

There was a programing language back in my father's days named "SAVE" which had the notable effect that you rarely lost the programs you wrote. Thats because you wrote "SAVE" on the cards so you knew what to run them against.

@MichaelT that is a smart idea

@WorldEngineer SuperUser?

user20683

@MichaelT that's my feeling

there is no way to access those directory that way without cd

user20683

@JeremyDicaire well go answer it on SU then :)

11:37 PM

@WorldEngineer no, I'm going to be downvoted for sure

im always downvoted

thats why I use SO as a last resort

and never comment/give answer

user20683

@JeremyDicaire Super User isn't SO.

user55340

SO is another beast altogether.

its part of SE

user20683

@JeremyDicaire And?

(sorry mistyped)

user55340

11:39 PM

SO has a 'fastest gun in the west' problem of people trying to answer things very quickly and jockeying for position on the answers.

user20683

we are not all the same beast.

haha well said

user55340

user55340

There are lots of SE sites out there... each has its own community that tends to it.

user55340

The culture on one is not always the culture on another.

user20683

11:40 PM

Math for instance loves Bikeshed questions.

user20683

they also tolerate homework whereas we do not

user55340

As always - questions about site norms and governance are best asked on Ask Different Meta since the comments here became dominated with what's on or off-topic here or on other sites. Meta allows a more careful discussion of the problems and merits of wiki questions - both in general and in specific here. Cheers and thanks for your assistance. — bmike Oct 22 at 22:35

Some of the same rules, but not all.

(read the tag wiki for that one to see the requirements)

kind of an ontopic question: is there a safe way to make a php/mysql website and make it opensource for contributor to..contribute?

@MichaelT wow!

user55340

One consideration about it that should be remembered, thats not digitally manipulated. It was a significantly worked on staged photograph that involved glue, scissors, holes in table, and a light under the table.

11:51 PM

@WorldEngineer Really? haha

user20683

@JeremyDicaire Stuff it on Github then you can accept changes as you want

user55340

pages.github.com

@WorldEngineer yeah but is it safe? like ppl will see all backdoors too (and ppl can fix them too though)..

user20683

@JeremyDicaire Firefox is open and secure

user20683

so is Ubuntu

11:52 PM

and how can I easily code it, upload it to github, and then "sync" the changes to the webserver?

user20683

@JeremyDicaire pretty easily

oh, wait I know this one...

@WorldEngineer you are right I shouldn't be that much paranoid

A: How to make a "git push" update files on your web host?

This is summarized from Using Git to manage a web site The key to the process is the server side hook 'post-receive' (more on git hooks at Customizing Git - Git Hooks and the githooks man page). This hook runs after the server has received all of the data. Once the server receives the data, it...

user20683

@JeremyDicaire The "much" is unnecessary in English.

11:53 PM

lmao

user20683

:)

user20683

"that" is used as "much" in this case.

really? I can jsut say : I shouldn't be that paranoid ?

user20683

yep

user55340

Yep.

11:54 PM

interestin thank you guys

user20683

in my dialect you usually put an emphasis on the that

user55340

Btw, neat another neat site within SE

user55340

hahaha cool

user55340

Thats the more 'advanced' one... there's also

user55340

11:55 PM

@MichaelT thanks for the link. when ppl (or me) make changes to github... I hope I need to approve them in order to sync the changes to the webserver

user20683

@JeremyDicaire you do

user20683

they submit a "pull" request.

@WorldEngineer ouff okay

I started getting interested in FOSS only a week ago (and I read a lot about it's origin) so I'm new to all github stuff

user55340

@JeremyDicaire Yep. And then you accept it to the main one. You can have multiple remotes on your machine, set up one remote to the website itself, and then you can do a git push website master

user20683

11:57 PM

@JeremyDicaire git can be used independently of Github

user55340

github is just a very easy place to use for git and hosting.

okay and if I dont use github, how ppl will make changes and read the source code?

user55340

(the company I work at is a 100% git shop, with our issue tracker and code all in github - private repos though)

(thats what i though but i wasnt sure)

user55340

You could... publish the git repo on the website itself.

user55340

11:58 PM

Or a way for them to download it.

user20683

Gonna go play Fiasco

user20683

see ya guys later

user20683

Don't break anything

user55340

Its 6pm here... I'm the last one out of the office... previous one left at 4:50... I should get heading out (the heat shut off and its getting on the cool side)
