Also much easier to prevent syntax errors like he had, I'd be willing to bet that his code wouldn't work and MySQL would give him "unknown column" error or some such.

Simon André Forsberg

@skiwi There is actually not a SE site about legal stuff unfortunately. I think many people have something against giving legal advice over the web. I appreciate your thoughts do. Hopefully there's no danger at all about it.

@Mat'sMug Well done! I'm glad that while I take it slow, others are still working!

Thanks Santa!

I am so bad at multitasking it's silly. My wife is amazing though.

Mat's Mug

multitasking...

rolfl

She can watch TV, write e-mails, cook a meal, and deal with kids ... all seemingly at the same time, and when I say "kids, be quiet, I can't hear TV, Lee what was that they said?" She'll be able to tell me word-for-word.

@rolfl Minus the kids part, I can also review code or edit a post. Sometimes I can also do homework.

Q: People looking for help?

A brief glance at this SE seems to tell me it's more filled with "why doesn't this code work" questions as opposed to "How could this code work better" (which I believe is the actual point of this SE). Best way to enforce the intention of this SE?

Mat's Mug

Could you give some examples of (open) questions? Questions about "why doesn't this code work?" are clearly off-topic. — Jamal ♦ 5 mins ago

Simon André Forsberg

@Phrancis Sorry but I downvoted your answer to that PHP question, I didn't think your answer added anything useful. The question uses concatenated queries, so in the end there's nothing wrong with the SQL syntax (except for the fact that it's concatenated)

@hichris123 Just had to link to that Jeff Atwood blog post. It summarizes it perfectly.

A: Can we ask reviewers to *not* focus on something?

Yes. It is fine to ask reviewers to preferably avoid commenting on something. Of course the reviewers can comment about it anyway, and then it will be up to the community - and the original poster - to determine if the review is helpful or not. If you're not interested in comments about naming,...

hichris123

hi

matheussilvapb

I know a little C++

hichris123

How can I use an arbitrary variable type in a for loop? I have a type ZZ (for large numbers) that I want to use in a for loop.

matheussilvapb

@hichris123 what you need ?

hichris123

Like this:

Donald.McLean

I don't even know ++ any more. Scala doesn't use increment and decrement operators.

hichris123

01:18

for(ZZ number = 1; number < 100; number++){

Mat's Mug

is ZZ a... type?

matheussilvapb

thats my question too

Mat's Mug

readability--;

hichris123

@Mat'sMug yup.

wonders what ZZ stands for

matheussilvapb

It should not have any problems

Jamal

01:20

I'm not sure how it's defined, but that may involve overloading operator++.

Mat's Mug

the guy was asleep when he named it

Donald.McLean

@hichris123 C++ doesn't care much what the contents of the three parts of the for statement are, it just evaluates them.

hichris123

@Jamal That's probably it, then.

matheussilvapb

Can you compile it @hichris123 ?

Donald.McLean

As long as they're legal expressions, it will work.

matheussilvapb

01:21

Yep

hichris123

I just tried it, and I got a: Error: conversion from int to non-scalar type NTL::ZZ requested.

Jamal

@hichris123 If it won't work as is, then the compiler should tell you that incrementing isn't supported.

Simon André Forsberg

@Donald.McLean I tried using i++ in Python, but that also didn't work...

hichris123

@Jamal I'm just getting the conversion error, but that's probably it.

matheussilvapb

The error is propably in your type zz

hichris123

01:23

hmm...

matheussilvapb

haha mr obvious here

hichris123

oh, I got it.

You need to declare a ZZ beforehand. It has to be like:

ZZ something;
for(something = 0; etc){

Mat's Mug

@matheussilvapb yeah, he's kind of a ....mascot

Simon André Forsberg

TTGTB, night

matheussilvapb

hm, but the earlier code should work as well

how did you defined zz ?

rolfl

01:25

Wow, high concentration of moderators.

hichris123

@matheussilvapb What do you mean? (fyi, it's from a library, NTL).

matheussilvapb

oh right

i havent seen it

oh man english verbs are impossible

is the last sentence right /

?

hichris123

Yeah, it is.

Mat's Mug

how did you define zz ?

hichris123

@Mat'sMug shoup.net/ntl/doc/ZZ.txt

Mat's Mug

01:30

did you x -> x is infinitive

hichris123

hmm?

Mat's Mug

@hichris123 @matheussilvapb wrote "how did you defined", was asking about it, right @matheussilvapb?

hichris123

@Mat'sMug Ohhhh!

nvm then. :P

Mat's Mug

lol but that explains why/how it works. ZZ is indeed a type. Why it's named ZZ is a mystery, but no longer how`for(ZZ number = 1;` can work ;)

ZZ Top

ZZ Top (pronounced [zɪː zɪː tɒp]) is an American Texas blues and Hard rock band formed in 1969 in Houston, Texas. The band consists of guitarist and lead vocalist Billy Gibbons, bassist and co-lead vocalist Dusty Hill, and drummer Frank Beard. One of the few major label recording groups to have consisted of the same lineup for more than forty years, ZZ Top has been praised by critics and fellow musicians alike for their technical mastery. Of the group, music writer Cub Koda said "As genuine roots musicians, they have few peers; Gibbons is one of America's finest blues guitarists working i...
