R stuff

Some general R tips:

When you need help with a function (i.e., write.csv) enter ?write.csv or help(write.csv) in R and it'll give you a manpage-like description of the function.
The CRAN manuals are good, also check out Quick-R. This helped me get up to speed.
A GUI like RStudio may be helpful.

Hey guys, I'm a freshman in college so I'm just kinda planning things out now for a Major in Computer Science (in an engineering program if that changes anything, doubt it will but the curriculum might be different, who knows), and I know Linear Algebra is really important for CompSci and it's required by my school either way. On the other hand, Differential Equations isn't, and I was just wondering if a class in it would be worth it? Does it apply to the field nearly as much as Linear Algebra?

Not as much, but most engineering programs require it. Are you sure you can get away without it?

Yeah, positive. It's either take Diff EQ with a third physics course(Waves, optics, etc), or just take a second chem or a 3000 level statistics course with no prereqs. I tested out of the first chem, and haven't taken it since Junior year in HS, so I'll probably end up doing stat.

Yeah, go with statistics. The CS program I'm in requires it, and it's a useful class to take.

Nthing this. DiffE is not particularly useful for CS unless you're planning to get into EE integrated circuit design stuff. Statistics, on the other hand, is drat useful.

Horrible, but useful.

I have to take a general Engineering Statistics course no matter what, and then I think the title of the extra course may be Basic Probability? I'm not exactly sure, it's a year or two off so I'm not too worried about it quite yet. Thanks a lot guys!

I'll second this, especially if you may also want the wiki feature in the future. I've been using it for a while and I rather like it. Setup was reasonably simple, as I recall. The only problem I've run into with it is that it uses a sort of obscene amount of memory for what it does, at least in its default configuration. It probably isn't bad enough to cause a problem for most people though. It only hurt me because I have it running on a fairly cheap VPS.

BitBucket allows unlimited private repos for free, though I've never used their issue tracker. They do Git repositories now, too.

That'll do.

This isn't exactly a programming question, more of a "who the gently caress knows what Facebook is doing" question, but since Facebook refuses to have a useful support system, I thought I might ask since SA is usually helpful.

My wife has created a facebook page (as in, a public figure page) and we've checked every option we can find to allow tagging, but I (and anyone else) are still unable to tag the page in photos or posts, even though I even have "liked" the page.

Does anyone know how this REALLY works? Anyone we've asked with a page that can be tagged just seems to say "I don't know, it just worked for me."

I want to make sure people visiting a webpage from a certain ip are shown a different file than everyone else.

So instead of https://www.domain.com/index.php they would see https://www.domain.com/index2.php.

I tried setting it up in .htaccess, but I keep getting errors. I attempted to follow what was written here.

What I currently have in my .htaccess:

code:

<FilesMatch "\.(ttf|otf|eot|woff)$">
    <IfModule mod_headers.c>
        Header set Access-Control-Allow-Origin "*"
    </IfModule>
</FilesMatch>

DirectoryIndex index.php

CheckSpelling On

ErrorDocument 404 /404.php

RewriteEngine ON
RewriteBase /
RewriteRule ^index\.html?$ / [NC,R,L]

Any help would be appreciated.

I'm trying to download the economic data for the last 5 years from this site: http://www.briefing.com/investor/calendars/economic/2011/12/05-09/ where the URL can be iterated through each week of each year.

It's so that people visiting the page from within the place I work at see a different version of the page without facebook and twitter widgets, since both those sites are blocked by the firewall and their browsers keep throwing up content filter warnings which we'd like to just avoid.

I'm guessing you have to be logged in to see the CSV download options?

iMacros looks like it could be easier than scripting HTML scraping in Python, but I'm not sure having never used it and having no idea about your skill level with JavaScript or Python. There's a JavaScript thread if you need help doing advanced stuff with iMacros.

I don't have a subscription ergo no easy csv download option, but given the table formatting, I'm assuming I can download in csv. Otherwise, I can download in tabbed format and import into a csv.

Oh, so you want the actual contents of that table, then?

There are some demos here: http://www.iopus.com/imacros/support/#demo that look promising for getting the data out, but it looks like you'll have to write a script to automatically scrape multiple dates and all the instructions are Windows only :\

This is the point where I'd just hack together something in Python or Lua (using either an HTML parsing library or some filthy regexes depending on how robust it needs to be) to get it into CSV.

Nothing shows up on Google. You should see if hspice will allow you to export data into a more standard format.

Yeah me too, but if he's got no programming experience, copying and pasting a VB script to use a macro that he can build with a semi-friendly GUI is probably the easiest way for him. I should say that I just assume he's a novice because I never see him posting in the Python, JS, etc threads, but I have been busy and doing a bad job keeping up with them, so maybe I'm off base.

It can output ASCII but I was specifically tasked with figuring out how to read the binary format. Right now I'm working on reverse engineering it.

Can it output Matlab format? There is an R package (matlab, appropriately enough) that can read those files.

I've got no idea on the Apache/.htaccess perspective (mostly .net based) but when I had to do the same thing I would check the IP on session start, see if it matched our static IPs, set a boolean (e.g. IsReservedIP) and then have content display on the page based on that. So if IsReservedIP = True then don't render facebook like, etc.

Is the ASCII in a standard format, like comma-separated values or fixed width formats?

It's string representation of floating point values with no delimiters, frustrating to read.

It's still probably a lot simpler to parse that than to crack the binaries. If you want, you can send me a small sample of the ASCII output at the address in my profile and I'll take a look at it.

Edit: I did a quick Google search for some sample output, and this looks like it'd be pretty easy to parse out with some basic regular expressions. That's going to be a much more pleasant approach than messing around with binaries.
