Yes, you have vbproj and csproj. When adding a new item, make sure you are selecting from the Visual Basic language list and not the C# one. They will have similar items.

Also, Visual Studio is trying to save you from your horrible mistake. It knows better.

Phyphor

I always thought it was the contents of the project file, because you'll get stuff like <Import Project="$(VCTargetsPath)\Microsoft.Cpp.Default.props" /> in it

urahonky

Sure enough it is loading a csproj file... No idea why.

bowen

The solution may have csproj in a similar fashion to what phyphor is saying.

Project("{F184B08F-C81C-45F6-A57F-5ABD9991F28F}") = "test_vb_app", "test_vb_app\test_vb_app.vbproj", "{31043FC6-6DB1-4019-BFBB-FE74511E2EDB}"

vs

Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "VFS", "VFS\VFS.csproj", "{2D957064-3E8B-44D5-BB76-1A9551863EBF}"

Nobody, either here or in my class's forum, has commented on my naive-bayes python script. Is it understandable? Did I use lambdas appropriately or am I overusing them?

I'm really close to graduating and yet I sort of wish I had another class where we basically just code stuff and then have someone who knows what they are doing tear into it. We had a course very early called Programming Practicum that was basically this, but it was also very much Object Oriented Design Review. Like "What is the difference between overriding and overloading" stuff. But I have learned an absurd amount of stuff since then!

bowen

Here's what I would say to you MBW: What is the practicality? Could you have done this better?

Outside of academia, coding is a vastly different game. Implementing predetermined algos like that, you're pretty much just measuring ease of reuse, efficiency, and correctness. Not much I can say or not say about it, looks okay from a code-reader's perspective and I know beans all python at the moment.

Monkey Ball Warrior

The practicality is not so high because this sort of thing is generally done on large datasets in a database, so I sort of doubt Python would be the language for large dataset crunching. I guess it is mostly useful for getting the algorithm straight in my head, or if this was a real project, prototyping it before implementing a real application.

Now that I look at it again I might be looping over the dataset more than nessicary, which with tiny little csv's doesn't matter but in the real world would be catastrophic.

My complaint about not getting enough constructive criticism in school still stands.

bowen

You learned one of the most valuable programming lessons, implement first, optimize later.

bowen

Also just upgraded to lion and updated xcode... yowza is 4.X far better than 3.X Feels like I'm in visual studio now.

Monkey Ball Warrior

Did you see this bowen? I thought the idea was pretty cool, but idk much about mac/iStuff coding.

I have only been coding for about 5 years after graduating but I rarely have any developer comment on the code I write. I feel that for the majority of developers
the only critic you will ever have a conversation with is yourself when you review your own code when you have to fix a bug later on. As long as you are keep trying
to be a better developer I expect your code is above average in quality.

No I did not, but thanks, that appears to be sexy.

I couldn't stomach the monotouch stuff, but this looks neat.

If you care that much about things you'll probably more likely be in the role of the person bitching about shitty code from a former colleague that you now have to support/fix...

bowen

Hey I've done that!

Monkey Ball Warrior

So far most of my real world experience as it pertains to other's work has been less "This code is crap" and more "How the hell am I supposed to understand this, there's no documentation and barely any comments".

bowen

And that's when you start from the beginning... oh god the memories.

In almost al the cases you've used map+lambdas to construct lists I would use a list comprehension. I find them easier to read, especially when you've got something like

sum(map(lambda x: (x-avg)**2, dataAsFloats))/(len(dataAsFloats) - 1)

which would turn into

sum([(x-avg)**2 for x in dataAsFloats])/(len(dataAsFloats) - 1)

I find Pythons lambda syntax a bit verbose and the list comprehension syntax more concise.

GnomeTank

Python's lambda syntax is annoying. Lambda syntax should be super light, as little as possible to express the concept meaningfully.

Monkey Ball Warrior

I have to admit, I never really understood list comprehension, so I didn't think to do it that way. That's much cleaner.

Also yes I very much prefer C#'s => lambda operator.

jackal

VB.Net's lambda syntax is pretty lol-sy.
Dim sorted = customers.Orderby(Function (x) x.LastName)
or for multiline

Dim sorted = customers.Orderby(Function (x)
        x.LastName
   End Function)

but eh, at least it has lambdas.

In one of the first Python books I read (or I guess tried to read) the author was going over keywords and for lambda he said something like, "I don't know why this is in the language. It seems useless." I set the book down and walked away slowly.

GnomeTank

Oh dear. How to write a Python book without knowing anything about Python; Next episode at 11.

Ruby has decent executable block syntax as well, though it has this oddity of differentiating between a proc and a lambda, which creates untold confusion in new Ruby programmers.

GnomeTank

Anyone know of a good place to find simple, nice looking, CSS based layouts for sites? I need something just really basic and elegant, probably two column, and I'd like it to be CSS layout.

iTunesIsEvil

Would Twitter Bootstrap work for you, @GnomeTank?

It's bootstrappy! And pretty awesome! I just built a whole site for my company using that.

GnomeTank

I have not heard of this thing until now. I am not even entirely sure what it is. It looks awesome, but I am trying to figure out how to even use it.

GnomeTank

Ohhhhhhhhhhhhhhhhhhh. I get it now. That is fucking amazing. it's exactly what I wanted actually. I just want to work on some awesome back end Ruby code, I don't want to fuck with a good layout. This gives me exactly what I want, plus jQuery, since I plan to do a lot of ajax.

iTunesIsEvil

Yeah, it really is awesome. I hate CSS and web-design so finding that was the equivalent of a god-send.

There's so much cool stuff embedded in there, from the nice tables to the image-set it comes with, all the way to the cool JS/AJAX stuff it'll do. The grid stuff is so simple but so awesome. It all makes sense, which is saying something for a web-library.

GnomeTank

So it seems like when you just DL it raw, it's just all the stuff it does slammed in to single files. All the examples use it in a different way though, which makes it slightly annoying :P I guess I could DL it using customize and get the individual components.

That's what I did. I just downloaded it, loaded the css in one of my web pages, and looked to see what looked different. Then started tweaking. I really need to just start from scratch now that I understand how it works, though.

You guys should also have a look at bootswatch.com. They've got a bunch of themes that are fairly nice looking using bootstrap for free and of course they also run a paid theme site, but I like several of the free ones better than most of the ones they charge for.

Halibut

New project at work is moving away from Struts 1.x, and towards Spring MVC. Thank God! I'm almost as happy as the day they upgraded to a (somewhat) recent version of their app server so we could start migrating to Java 1.5.

Jasconius

Bootstrap is literally the best CSS "framework" ever written.

It is beyond doubt.

Infidel

I shall have to mess with bootstrap on a project someday.

On another issue, which is highly stylistic choice by me, is that instead of:

    if dataLine[wanted] in classes:
        classes[dataLine[wanted]].append(dataLine)
    else:
        classes[dataLine[wanted]] = [dataLine]
        probFuncs[dataLine[wanted]] = {}

I'd do

    try:
        classes[dataLine[wanted]].append(dataLine)
    except KeyError:
        classes[dataLine[wanted]] = [dataLine]
        probFuncs[dataLine[wanted]] = {}

Because I'm a "It's better to seek forgiveness than ask for permission" kind of guy. Especially in Python where exceptions are 'first class' control flow constructs (by that I mean library methods raise Exception rather than return error codes) and in your case where it looks like the appending will happen a lot more often than the creation of new entries so the exception way will be more efficient.

You could also do

variable = classes.get(dataLine[wanted],[])
variable.append(dataLine)
if len(variable) == 1:
    probFuncs[dataLine[wanted]] = {}

Orrrrrrrrrrrrr

variable = classes.get(dataLine[wanted],[])
if not variable:
    probFuncs[dataLine[wanted]] = {}
variable.append(dataLine)

But that doesn't super help anything much. The get method of a dictionary returns the second argument if the key isn't present. And an empty list evaluates to False

So I'm usually a JAVA whore. Love it. I could write a web crawler in that, but, what language would you guys suggest I write one in?

jackal

I'm being told to work on a legacy VB6 app. If I post my address will someone come over and kill me? Something quick and painless would be nice, but I'm not picky.

C# might not be a bad place to start to move you away from Java.

Python or Scala. Python is going to be easier if you're going to do anything more than a super simple, naive inspection of the data on the page due to being more mature (well, I'm sure there's a good java lib for it you can use in scala, but that sort of defeats the point) but I've written basic crawlers in both and doing one a concurrent one using actors in scala was cool/interesting exercise.

Or Perl, because the world needs more Perl.

GnomeTank

I have to say, Twitter Bootstrap and jQuery have made getting this Diablo 3 crafter net up really easy. I am doing it as a quick and dirty project for the Diablo 3 thread. Really I've just been looking for an excuse to do a small, easy to finish, RoR project.

This is totally a job for PERL!
