1. STL, I love you, but I hate you. Templates, You guys can suck a fatty too. You’re so useful, but just such a pain in my patoot. Of course, I treat you well when we’re writing together on our own… but the pain you cause me when you’ve run off with someone less responsible than me is excruciating. Where’s the love?
2. Haskell … oh boy Haskell. When I discovered the ease of Python after being raised in the world of C/C++, Python was the Orinoco Flow of my programming world! Light and airy, I swear as I checked my indentation that first time that around the world hippies were swaying and holding hands rejoicing about something or other. But Haskell.. you dirty rascal.. you’re my Korpiklaani. You’re a wild beast that’s angry and ready to be let loose on anything that needs a quirky methodology, and yet at the same time, you’re catchy, and enjoyable, and oddly enough, make perfect sense. I don’t know what it is about Haskell (or Korpiklaani, for that matter)… it’s clunky syntax and functional modus operandi are bewildering, but I like the way it works. So much of Project Euler, if done in Haskell, are one-liners, and the flow of them actually makes sense. Haskell seems like doing surgery with a chainsaw, and miraculously, the patient not only is cured, but has grown organs for breathing underwater and x-ray vision. It’s just got that kind of whiz-bang.
3. Left 4 Dead. I haven’t had much time to play, but boy oh boy. If you haven’t seen this game somehow.. let me sum it up for you: Post-apocolypse + Zombies + shotguns + multiplayer first-person-shooter = love.

And that, boils and ghouls, has been what my last two months has been all about. Let’s see if I can make it around to actually post again before I’m 70.

Work is going well. The students have their finals this week, which means the next two weeks I basically get to do nothing. For the next 4 or 5 days though, it will be sheer madness. Students seem to want to wait until the last minute when they’re desparately behind to ask for help, by which point they’ve frustrated themselves so thoroughly, they expect me to step in an just do it for them (to which I respond by giving them a big ol’ ticket for a free trip on the FAILboat). I’m also amazed sometimes by how much people want to (yes WANT) to not catch on, and continue to make excuses as to why they can’t do something instead of just learning to do it. It makes me wonder if in the past (or even currently) I have done the same things. I’d like to think not.

School, while intriguing and challenging, has been eating up a good hunk of time. I’m OK with that. In my programming classes over the past few weeks, I’ve had the pleasure of re-implementing the unix tools “cat” and “grep” in c/c++ and the FreeBSD passwd diff’ing security check in bash. It’s kind of neat to dissect and re-implement the tools I’ve been using for so long. While they seem like trivial exercises, it teaches alot about why software engineers design software they way they do. Who would have thought there were so many ways to put the contents of a file to STDOUT? Now the question is, whose way is faster, better, and more concise, and why is that? I know when I’m doing work for production, a lot of times these questions don’t receive alot of attention. “Oh, it compiles? Ship it!” It’s nice to see some time spent discussing the science behind our science. ;)

Fun stuff.

Since the recent laconica updates, lopost is indeed broken. I have not had the time to fix it. Sad but true. I’ll probably rework it over the semester break. Chances are I’ll have to take a look at the way gwibber does it, as my code was based on the original python at the laconi.ca trac, which no longer works.

I’ve also been asked to help out with the SQL security libraries for Photon CRM, although all of that is still in the planning stages. I’ve started writing some documentation (as in anything that doesn’t exist yet, document first, implement second), but we’ll see how much time I end up having for actually writing the code.

Ok really, I don’t make people cower in fear. I feel good knowing that that girl there didn’t know how to copy a file on to her flash drive, but now she both hates me for wasting 30 minutes of her life making her learn how to copy the file instead of doing it for her, as well as knowing how to copy the file itself. Sure, people don’t like to learn. They want things to be done for them. I am not of this mindset. I would like to learn at least the bare minimum of everything I should be involved in, though I make no pretenses about leaving expertise to the experts.

For now, it is likely to be quiet on this page. It has been 5 weeks since my last update, but those are 5 weeks well spent learning and teaching. The only thing I have in the running of interest to the outside world is a revision of some of the packages for Ninjas and Pirates, as I’m trying to get the forum games integrated with the actual forums. I may end up posting about that. Otherwise, Haskell has been sparking my interest, but I don’t see any likelihood of actually having time to learn it anywhere in the near future.

So, until next time, I’m off to give the world some PHP and a piece of my mind!

Update: Code posted @ lopost

1. I feel like I can handle my own social networking, thank you very much. This is why I have my own blog, where I aggregate what I do at other sites (like the music I listen to and articles I digg) all on my own.
2. Sites like Twitter and Facebook run proprietary software. No one is able to see, modify, or redistribute the code for these sites.
3. Said sites also maintain licenses that can restrict what you post, and call into question the ownership rights of anything posted to them.

My friends over at Linux Outlaws have solved this problem for me. They’ve installed a service called Laconica, which functions much the same way as other micro-blogging software, like Twitter. The difference, however, between this and other services is that it is open-source software, and it is being run by some fellas I consider friends, which means that I am indeed, handling my own social networking. On top of that, I don’t feel like I should ever have to worry about doing something like aggregating my own posts over to this site and wondering if I really have a right to re-distribute my own content. One more neat part? You can subscribe to others’ tweets, even if they’re not on the same Laconica server.

If you’re interested, head over to Linux Outlaws’ Laconica site, and sign up. Also, if you have any interest in computers or Linux or you just hate microsoft, you should really head over to their podcast website and listen. To it all. Dan and Fab kick ass.

Ok, back to implementing a (yes, really) four-function calculator for fractions, in C++.

But yes, I’m still around, and I haven’t forgotten my meag… erm, “highly exclusive” readership. So, how’s my week been?

Ok. Been working on fixing my damned pointers. I have one that keeps faulting when I delete it and I don’t know why. So, as angry as computers make me, I was glad this morning.

Why? I did a project euler problem (#15) without a lick of programming. The question was in a 20×20 grid, how many combinations of paths are there from one corner to the other. Welllllll permutations tell us it’s the factorial of 2 times of the size of your grid, all over the factorial of the number of possible choices multiplied by factorial of the the number of columns. In easier terms, that’s

(2n)! / ¹n! * ²n!

And since our grid is 20×20… well. You figure it out.

Hope to be back soon enough!

Yes, I removed the actual answer so as not to be a spoiler. However, I will include my full source code, as I’m amazed at how simple it was, and maybe you’ll enjoy it too.

#~ Project Euler #9
#~
#~ Solution by Nathan Dotz - nathan.dotz@gmail.com
#~
#~ Problem 9
#~ 25 January 2002
#~
#~ A Pythagorean triplet is a set of three natural
#~ numbers, a b c, for which,
#~ a2 + b2 = c2
#~
#~ For example, 32 + 42 = 9 + 16 = 25 = 52.
#~
#~ There exists exactly one Pythagorean triplet
#~ for which a + b + c = 1000.
#~ Find the product abc.
#~
#~ Solution:
#~ Utilizing the fact that given any integers
#~ 'm' and 'n', a triple can be generated by:
#~ a = 2mn, b = (m^2-n^2), and c = (m^2+n^2)
#~
#~ a little algebra gives that if:
#~ 2mn+(m^2-n^2)+(m^2+n^2) = 1000,
#~ then m(m+n) must equal 500.
for m in range(1,50): #this should be more than enough
  for n in range(1,m): # m > n, else m^2-n^2 < 0
    if( not 500%(m*(m+n)) and (2*m*n + 2*(m*m) == 1000) ):
      print "a = " + str( 2*m*n )
      print "b = " + str( m*m - n*n )
      print "c = " + str( m*m + n*n )
      print "sum = " + str( 2*m*n + m*m - n*n + m*m + n*n)
      print "product = " + str( (2*m*n)*(m*m-n*n)*(m*m+n*n) )


So no, world, I haven’t forgotten about you. Now, can you hold this cable while I go pull the other end through my wall?

So, absolutely without any permission whatsoever, I snuck down and took pictures of his latest creation — this kind of humanoid dragon thing. Tell me this isn’t badass!
