Instead of telling us about your code and providing links to your code, you should include your actual code. And with that said, if you actually want a review of your actual code, you should consider whether Code Review might be a more appropriate venue. — nhgrif 42 secs ago

> Each of these functions has 4 parameters – the 4 non primary key fields in each table. There is NO DATA SANITATION performed – the 4 values provided to the function will be placed in a simple SQL query. For example,
addCustomer(‘Sgt.’, ‘Robocop’, ‘Police station’, ‘000’); will execute the SQL:
INSERT INTO TABLE CUSTOMERS (FIRSTNAME, LASTNAME, ADDRESS, PHONE) VALUES (‘Sgt.’, ‘Robocop’, ‘Police station’, ‘000’);
and the database will automatically assign a CUSTID to the new record. This is obviously not best practice in real-world applications due to security issues and SQL injection, but f

@skiwi Wow.
 
@skiwi I'm kinda offended that more than two people have to be over 50 to play Dominion, Settlers of Catan, Backgammon, Go, Chess, Carcasonne and Scrabble
 
lol
 
11:16 AM
and yes I went through all paths
 
@Vogel612 I think it's under 50?
I only get to Cribbage in the case you describe
 
hmm.. oh right...
the other way round sucks, too.
also you need one over 50 for Backgammon, Go and Chess...
 
It's probably accurate to some degree
 
I've always wanted to try Go, but I can't find any opponents.
 
@Mast let's go ~badumm tish
 
11:19 AM
I've would be willing to try Go, but the only question is when
 
*disapproving stare*
I would be Go to try Go.
 
Go is also quite hard for computers to play.
 
Oh.
You guys mean the game.
Not the language.
...yeah me too
 
yeap
 
Of-course, if you manage to build a program playing Go, you should write it in Go.

on an unrelated note.. did you know one can submit an answer up to 4 hours after a question has been closed?
 
@Vogel612 I assume you'll have to start writing the answer before it's closed?
 
I'm not quite sure...
 
Wow.
That's what happens when you put your verification client-side.
 
There's a good reason for it
I believe the grace period, though, was meant for users who did not have JavaScript enabled or for some other reason could not be notified that the question is now closed, so they continued typing not knowing that fact. — animuson ♦ Dec 5 '13 at 21:31
 
11:23 AM
@Vogel612 I do know it's possible. It happened to me once that I could post an answer.
did not know the 4 hour limit
 
of course a better reason would be to just not cater for users with JS disabled, but we don't live in a world where that can always happen (plus JS may get disabled due to firewalls blocking scripts, slow net connections...)
 
Phones with crazy operating systems not supporting JS for security reasons, etc.
The latest answer by Wizard sounds like a load of horse crap though.
 
I got to work and it turns out I'm not even needed here any more because the bug they wanted me in to fix has already been fixed.
This is why I need a PC that can handle working from home..
Or, rather, either a better work laptop or for our infra team to let me remote in using my extremely powerful home pc
 
Or just, you know, communication ^^
 
There was plenty of communication
Not much communication can do when you're in a taxi because you can't work from home, though
 
11:36 AM
Phone?
 
Well, I mean, yes my colleague called me telling me that he had fixed the bug
But I was stuck in traffic in a taxi on the way to work
If I was able to work from home I would not have been in the taxi :P
 
They don't have a gateway at your work for remote access?
 
We have to VPN using our work laptops
You cannot access the network from anything other than your work laptop
And also it appears some programs do not work over VPN
¯\_(ツ)_/¯
 
It saves your IT department a lot of headaches, but it's quite limiting.
 
I understand the security concerns etc
But... meh
Still... there's talk about getting Macs, whichi might make it a bit more difficult to enforce some of these security rules
At any rate, as I'm here.. I might as well do some coding
 
12:12 PM
wtf? our firewall has just gone on the fritz and is suddenly blocking any connections to the npm registry (again)

^ Goes for PhD... does not like papers?
 
It's the reason I never went to university.
I've worked in academic environments, but writing papers simply can't interest me.
 
I've barely seen any papers in my Bachelor though
I'd probably like reading and writing papers, but I'm just not smart enough for that
 
I've read a fair share, during my Bachelor and after, but writing them is a completely different matter.
 
2:55 PM
Now I'm confused, you never went to university but did read them during your Bachelor?
 
College isn't university.
Or whatever HBO is called.
 
Ah..
 
That's where I got mine.
 
Technically it's an university in international terms (had this discussion with a friend on HBO for some time), it's just that "our university" can be compared to MIT, etc. (though still less prestigious) and our HBO can be compared to any university in any country
To put it simple... In most countries you have above average and regular universities, here we have universities and HBOs
I didn't know you had to read papers at our HBO though
 
3:14 PM
Writing them isn't too bad, but reading them is tricky.
I have trouble with statistics beyond the most basic stuff.
 
The only HBO I know of are the ones doing Game of Thrones... I assume this is a different one?
 
@skiwi You don't have to, but it makes the final stages a little easier if you get your information from wherever you can find it. Including papers, as it turns out.
