@JimmyHoffa - Thanks for taking a look at it. I sometimes have a problem finding anybody for a second opinion on certain design issues.

@JimmyHoffa Better to think of it as training for a marathon by jogging while carrying 100 pound weights. I figure after a while if I get to use a real language I'll be unstoppable.

of course. That's why I enjoy code reviews, lots of places you'll never get any other feedback (and even then none). I always feel like I'm missing some huge hole if I get no critical feedback

New job that's no problem at all, these guys are very analytical, sad how few engineers are

A nice alternative to code reviews is to write a technical document, have non-technical people read it, and then get a "code review" consisting of people asking "what color token ring will you use" type of questions. But hey, whatever works for you.

My type of code review is handy because it allows non-technical people to specify requirements in terms of design.

As an aside, that old PC for audio... the sysadmin came by today... got redid the drive, reinstalled the OS, got the application working for ~20 minutes. Did a reboot to make sure all the settings stuck... and it failed to come back up. le sigh

Q: Asking my project manager for a code review is a good idea or wrong?

I have completed my coding part in our project and I would like to have a code review with my project manager in overseas, however I am little scared of asking him as I am a fresher. I am thinking that if someone(like Sr. programmer) reviews my code so that I can improve my coding style. Ask...

is there any reason this should stay here rather than go to programmers?

thoughts?

thorsten müller

Anybody knows if reputation on StackOverflow allows to use the chat room here if Programmers.SE rep is 1?

gnat

@thorstenmüller if there's association bonus (100), it is sufficient for chat (requires 20+); my understanding is this is by design

programmers.stackexchange.com/privileges/chat

thorsten müller

no, he has only some 29 rep on SO and 51 on Area51. It's the guy from this question:

Q: Virtual lifeforms a.k.a implement life in the computer

Is it possible to create a program/application/algorythm/anything that is able to create a virtual dimension with virtual lifeforms in it? Definitely, what is necessary to tell about a program that it simulates lifeforms? Because there are some of them, such as Conway's Game of Life, or GenePool...

theory ideas implementations simulation

@gnat I agree! oh wait that was my suggestion... :)

gnat

@thorstenmüller no luck then, unless I missed some recent feature change...

@thorstenmüller @gnat Yes, 20 rep network wide is enough to talk in chat. It's a recent(ish) undocumented change.

Also, the 20 rep restriction is to talk in chat. 19 rep users can still come in here and read the transcript, as can unregistered users (if they have a direct link).

@MichaelT Isn't mega-old hardware fun?

enderland

@JimmyHoffa dont even talk to me about that. I'm trying to connect a PCMCIA card to a non-2000 laptop :P

Jimmy Hoffa

@enderland Have you tried just finding any open space in the laptop case, putting it in there, and then claiming the laptop ate it and they'll have to buy another laptop?

enderland

@JimmyHoffa oh how I wish it was that easy to get a new laptop here :)

awesome paper on zippers, I presume, just because it has the coolest name

Ok so it's actually a bunch of haskell nonsense I guess, but it's still the best title for a paper on zippers ever

enderland

from scanning it, it's also written in a pretty enjoyable fashion. though i like clowns! :P

gnat

@YannisRizos wow that's great to know. BTW what about migration WP guys discuss?

3:21 PM

@enderland I don't see what's specific to coding here, to me this reads more like a question on how to approach one's manager (It's a "people problem", not a coding problem). user1671639 isn't asking if code reviews are a good practice, they already know it is. — Yannis 49 secs ago

@gnat @enderland People on the Workplace should understand that a migration starts with an off topic vote. If the question is not 100% off topic there, it shouldn't be migrated. If it fits the site, even slightly, first instinct should be to edit it and keep it where it was asked. Also, the "it might get better answers elsewhere" argument doesn't apply: It's a young(ish) beta site, almost every one of its questions might get a better answer elsewhere.

Jimmy Hoffa

@enderland They scare the hell out of my wife, that irrational fear of clowns myth isn't made up, it's a real thing oddly heh

gnat

@YannisRizos that one has been closed as off-topic but now gained 2 reopen votes there. Also, edit in revision 2 made it look closer to Workplace than Programmers

Yannis Rizos

@gnat 2nd re-open vote is mine.

gnat

3:56 PM

@YannisRizos okay, that made me review the revised version a bit closer and jump the bandwagon. :) Looks like it's going to stay there

Yannis Rizos

4:08 PM

@gnat If it gets migrated, I'm sure we can find a way to make it work here, it's not horribly off topic for us.

I want the next upvote I get to equal 3 rep...

and I want idris to be finished and the most widely used language around so I can work in it full time, tough

finally somebody puts a lightweight wrapper on WAI/Warp so you can create a stupid simple restful website hackage.haskell.org/package/scotty cool

user20683

@JimmyHoffa I figured out a good c project, I think: determining Eigenvectors of a given matrix

Jimmy Hoffa

8:19 PM

Perfect. Something algorithmy/mathy like that is key because that's what people do in C when they're not writing drivers

user20683

@JimmyHoffa it's also a known "hard" problem

user20683

high poly time comps

user20683

it's also actually useful because it figures heavily into computer vision

user20683

you determine motion by figuring out the eigen vectors of a given blob in a given image

user20683

I really only have one regret from my CS program and that's not being more solid on my math

user20683

8:26 PM

I suppose I can always autodidact that later

Jimmy Hoffa

@WorldEngineer And if that doesn't work, you could wait ~30 years and Otodidact it when the sniff-n-learn is released

user20683

@JimmyHoffa I figure do some kind of graph something in Python since it has a really good graph library called Networkx

user20683

maybe parsing of strings and storing in a dag or some such.

user20683

@JimmyHoffa I think I linked that a while back

Jimmy Hoffa

@WorldEngineer yeah, that makes sense, just split the contents of a file on " " and stuff the tokens into a DAG with some search

or some such arbitrary nonsense

user20683

yeah

Jimmy Hoffa

Ah, I just stumbled onto it

And what're you going to do for Java? Here's a stupid and I mean *stupid* simple program that makes it clear you know java: Command line calculator. It loops reading line, parses the line and calculates it:
3+2
=> 5
3*2+4
=> actually I don't know, but whatever
ARGARHGAR!!
=> Invalid.

anorton

10:12 PM

@JimmyHoffa eh... how exactly is that simple? Are you accounting for order of operations?

Jimmy Hoffa

@anorton it's easy because it's completely sequential and has all of one single-domained body of functionality: to parse a very simple grammar and associate a small fixed set of terms to functions

anorton

Hmm.... great. You've just made me decide already what I'm going to do over the weekend. :P

Jimmy Hoffa

string arrr = Console.Readline();
string.Replace(arrr," ", string.Empty);
string[] participles = arrr.Split(_operatorsList);
and you're halfway to an AST, intersperse the operators back between the participles by order of their appearance in arrr and now you just loop the array of strings for each operator one at a time based on order of precedence

or do the whole thing in any number of other ways

it's really not a lot of work compared to lots of things, the number of cases is small

I would do something more complex but semantically meaningful in constructing the AST, but point being you can do it with a dumb AST in procedural style with very little work

(that was C# btw, I don't know Java off hand but I'm sure it's got equivalent functions, the languages are practically transcompilable...)

If you want something to do for fun go write it with dependent typing and have a total calculator with peano arithmetic

Jimmy Hoffa

10:38 PM

(total as in en.wikipedia.org/wiki/Partial_function not total as in complete)

raganwald.com/enchanted-forest/horton.html holy smokes, this guy puts the alligators explanation of combinators to shame in terms of alagorys-for-advanced-topics

also, he is conclusively insane just for having written it that way. It's like the time cube version explanation of ?? I can't bring myself to actually read the whole thing to determine, I think it's some intuitionistic logic

or maybe just some combinatory logic, either way it's unrefined nonsense

user20683

@JimmyHoffa post-fix calculators are used to teach stacks in Data Structures

that would involve Java and a database
