The Purpose: Log information directly from the utilities output into a MySQL table using bash. No real reason for the script other than “Can I do it?” and “I wonder if I can analyse/graph the data later..”. This is not going to be supported. What you see is what you get.

The Script:

#! /bin/bash
# Takes the output from /usr/bin/sensors, parses it into temperate and fan statistics, and inserts it into a local MySQL database/table.
# Author: Matt Kava of http://mattkava.com

locsen=”/usr/bin/sensors” # The location of the sensors utility
sensors=”lm_sensors” # The sensors pkg name

# Test if the sensors pkg is installed
rp=`/bin/rpm -q “$sensors”| grep not`
if [ ${#rp} -ne 0 ]; then
echo “The pkg $sensors is not installed. Please install it. Exiting.”
return 1
fi

sql=`/sbin/service mysqld status| grep stopped`
if [ ${#sql} -ne 0 ]; then
echo “MySQLd is not started. Cannot log any information. Exiting.”
return 1
fi

Besides that, spent Saturday at my girlfriend’s parents for her dad’s birthday (he’s only 45.. my mom turns 55 later this year with my dad not too far behind..) and got back at nearly 2am. Was a ton of fun heading out there to see them and pester their kittens/cats. And today my girlfriend and I biked around the city the bit. Went to Pancheros for an awesome burrito, and then to a couple movies afterwards (Airbender /sucks/ and Prince of Persia: Sands of Time is pretty awesome throughout [nice visuals, good PoP feel, good stunts, good story surprisingly]). So all in all, fun weekend and… NO TAEKWONDO THIS WEEK!! WOOOOOO! =D

Anywho, back to the grindstone in the morning. Whee..

Tons of Halo 3 was played. Some off-and-on gaming was done by folks who weren’t playing Halo at the time. Eventually around 11:30pm we got 6 computer rigs together for Rise of Nations. 3 v 3 gets a bit hectic, especially for the folks whoever never played a RTS like RoN before. Either way, it was a lot of fun. Especially when Cody didn’t have a missile shield and everyone kept dropping nukes on his head.. even people on his team. It’s amazing what a little nuking can do the the Armageddon counter… going quickly to zero. Game 2 ended the same way but with only 4 people playing in a Free-For-All game. 30 minutes of people and most people were ready to start development of the last tech and start attacking each other. Using the turn-and-burn tactic with nukes isn’t as effective as it could be, especially when its Nuclear ICBMs and not just the normal missiles. Things seem to die in a much larger area with those ICBMs. Hrm. With everyone calling it good at 4:30am, it was a fun 12 hours plus of gaming, and totally worth it. Looking forward to the next one in probably a half month, this time hopefully on campus though. =)

I may put some photos up soon, if I can get them off my only camera (my phone…). Not too many but enough to warrant a little effort.

People who came: Zach, Cody, D, S, Drew, Sam (and his girlfriend Amanda), Joe (even though he just hung out and didn’t game much), and obviously myself. Hope everyone had fun eating my awesome pizza and playing games with friends. Even Amanda who really looked like she didn’t want to be hanging out with a bunch of geeky gamers. =D

Until next time.

So yay for new apartment.

And.

Scheduled posts.

Neat. <3

I had found a place to live with D and S (I’m currently living with S), but the lady allowed somebody else to sign paperwork so that the place disappeared. I had told her, much to my annoyance later, that I wanted the place and once I got paid, would pay for the application fees for us all and a part of the deposit.. just to get the ball rolling. That was last Monday/Tuesday. So Friday, I find out that papers had already been signed. It’s a minimum of 2 days waiting period after applying before the background check comes back, so that means the other folks were allowed to apply Tuesday or Wednesday and sign the papers Thursday. Nobody called me to see if I still wanted the place (which would have been good form and communication), so I didn’t have a chance to tell the other folks to GTFO prior to lease signing. Not the greatest place, but the location was where it was at. That was the biggest reason I wanted the place. Closer to MSUM and Taekwondo school #1, nice for D for MSUM as well, and great for S so she could bike to NDSU this fall. Either way, the place is gone and we’re not cramming into a 1-bedroom for a year. Frick no.

So the hunt continues to find a decent place. Did find a nice townhome for 800$ a month that was everything we wanted, but.. it was signed away on Friday. Would have been great for the 3 of us in a nice spacious 2-bedroom. Good location, allowed cats, and for 800… we could swing a nice place. Plus MidConn could give us Internet/Cable. That would have been awesome (same with the last place mentioned).

So after that, nothing else has came up that is move-in-able this August so far. Prairie Property Management doesn’t have anything for 2-bedrooms this August in Moorhead anymore. Which sucks. A lived in one of their buildings for awhile, and didn’t have anything bad to say. Either way, with the circumstances, the plan of engagement is to compile a huuuuge list of apartments (possibly throw together a small website) and start looking again.

So if anybody has any decent place they know of for living in the Fargo / Moorhead area, I, S, and D would all appreciate a heads-up. You can find D and I on IRC (NFNet) as always. Drop a comment here or an email if you prefer.

Later folks and thanks for reading my ramblings.

-Matt.

This is half the reason I really hate the industry I’m in. If I come up with what I think is a neat and original idea, implement it, and start a business around it.. somewhere in that process, I might get a lovely message saying I am infringing on a software patent.

Looking back to Dmitry Sklyarov‘s arrest in 2001, they took 6 months of his life and never said anything close to sorry (from what I remember of the story at least). Sure, he was doing something that I morally don’t agree with, but it was legal for him to do in Russia so there is no reason that things should have gone as far as they did. Sure, since I’m not going to be creating something like his project anytime soon (or at least, not that obviously) but I don’t want to get thrown in jail for any amount of time because somebody else has a patent somewhere that fscks me over. I’m a huge supporter of Open Source and I wouldn’t be surprised if something that I make in the next 20+ years falls under some patent somewhere and I get a lovely letter someday..

Software patents need some work.. but I know I don’t have the answers other than knowing I don’t like them. =)

A screengrab of the website at the time of this post. You can see the timestamp in the image as well! Neat. (If this looks fuzzy or whatnot, click to see the full-size image.)

As you can see above, it’s a pretty simple little site at current. It doesn’t do much other than look like a terminal (from a fictional SSH login) and provide some links. Well, besides make people who hate the <blink> tag cringe. >:) Written entirely in PHP and utilizes only basic OO and PHP concepts, it’s small and quick to generate every time. Plus since it doesn’t actually take any input from the user, it’s reallllly small.

Any comments are always appreciated. Catch me on IRC (NFNet) under the handle Mkava or leave a comment here. The source is linked as well.

Oh, and you can find it at home.mattkava.com, for the time being. It may randomly disappear.. as this is a playground website for me to try things out in.
