Recently I wanted to set up a computer to act as a network storage server. I was looking around at the available open source software and I found a neat little package called FreeNAS. FreeNAS is based on FreeBSD which is basically another unix-type operating system. Being pretty familiar with Linux, I decided to try it. It turns out it is an extremely versatile and easy-to-use piece of software. Not only does it have an NAS server installed, but it also has a bunch of other server capabilities pre-installed. It also has an extremely intuitive web interface, so once it is set up, about ten minutes on a moderately fast computer, it no longer needs a monitor or keyboard installed. From the web interface you can do everything necessary to setup all the different services it has available.
At the moment, it has three different drives in it: a 300 GB Western Digital drive, a 160 GB Seagate drive, and a random 40 GB drive for a total capacity of 500 GB. (GB not GiB) :-( These drives are installed in an old tower I had laying around. The tower has pretty modest specs for a server. It has an AMD Althlon processor, 600 and some odd megabytes of RAM, and an old 10/100T ethernet card. The graph below shows the traffic through the ethernet card and the CPU load when transferring a 700 MB file across the network and using the samba server to serve iTunes with its music files.


As you can see. It doesn't take very much power to run FreeNAS. Overall, it works very well for what I need.

This is a pretty cool video I found via Hack a Day. It is a video of bullets hitting different materials filmed at a million frames per second. http://www.youtube.com/watch?v=QfDoQwIAaXg&feature=player_embedded

July 18th. The last time I updated. It is now September 5th. Forty-nine days since the last update. In that time, I have finished my summer job, driven from Maine to East Texas, had two weeks of classes, and been kept extremely busy. I will start with the most recent and go backwards in time. Tonight was interesting. It all started with a movie "on the mall" but because of rain it was forced to be inside the new Saga, the school cafeteria. The student activity counsel was showing UP! A Pixar film which was definitely worth watching. (I won't ruin the plot, you will just have to see it for yourself.) After that some friends and I were hanging out in the dorm lobby trying to find something to do. We decided to play sardines in a park across town. Picture this about thirty to forty people going to a park at five minutes to eleven at night. It was rather crazy. Anyway, we played for about an hour and a half then the police showed up. Apparently the park closed at 11 instead of at midnight like we thought. They were very nice about it, but they obviously knew we were from LeTourneau. (all of the cars had LeTourneau stickers) :-) Then we went to Walmart and did this thing called Freeze. Basically the whole group has a prearranged time to just stop and freeze in place for two minutes. We got a few strange looks, and had lots of fun. School started on the 25th of August. I am taking 17 credit hours of classes, and each class has its own project. So I haven't had nearly as much time as I have had previous years. Then on top of this I now am not only a tutor but I am also a grader and a lab tech at the Machine Tool Lab. This semester is going to be interesting. The drive from Maine went well. I left on a Thursday and got back to Texas in the early afternoon of that Saturday. I was told it would take three long days of driving. It didn't. It took two and a half long days of driving. But everything went well, I just slept in rest stops on the way down. Overall a good trip. Two days before I left Maine, my boss wanted to get one of the bigger projects of the summer at least done enough that he could finish it off on his own. So on the Tuesday before I left, we put up a new antenna on a tower in Lincoln, Maine. That was an interesting experience. I didn't do a lot of tower climbing this summer, but I did climb a couple of towers. One tower we were taking old antennae off. That tower was only about 140 feet tall. The tower in Lincoln was closer to 180 feet tall. It becomes quite fun when you are 180 feet in the air with nothing between you and a long fall but a harness strap and a slip of foot or hand and it starts to blow and rain. Fortunately for me the tower was well guyed so it didn't sway at all, and the wind and rain didn't last for very long. We got most of the antenna up, but we found that we were missing a few parts, and some of the parts we got were the wrong size, so we didn't quite finish. Overall the last month and a half has been extremely hectic and fun. I kinda expect the next few months to be as busy or busier, so it may be a while before I end up updating again. So Long.

Well..... I hadn't realized it had been so long since I last updated. You know the old saw, time flies when you are having fun, it is true. Life has been pretty busy. Usually for the Fourth of July, my family goes over to some friend's house and we have a pretty decent private display. But this summer being in Maine and all, where all fireworks but sparkelers are illegal, I didn't set off a single firework. Instead I went with the Bouchards and spent a couple of days on the coast near Arcadia National Park and saw a fireworks display in Bar Harbor. It was quite nice. The sky was overcast the whole time we were on the coast except for a couple of hours. But it didn't rain until near the end of the fireworks display. This summer it has apparently been rainier and colder than usual, but last weekend it was sunny and warm. Warm being about 75 degrees. :-) So the Bouchards and I went to a beach. Quite fun. It was the first time I had actually swum in an ocean that I can remember. Today we were going to go Whale watching, but one of the Bouchard girls wanted to go when we went, but had something else she was doing. So I got to just spend the day hanging out with the rest of the Bouchards. I finally closed my FaceBook account. A couple of months ago, I got fed up with all the junk on FaceBook and quite using it. So today I decided that I really didn't need to have an account if I wasn't using it so I totally deleted it. I don't like the whole social networking thing. Rather than have 200 "friends" on facebook who I hardly know and rarely talk to, I would rather have two or three friends in real life who I talk to a lot and know well. On top of that I didn't like the applications that would ask you to rate your friends against each other and then go to your friends and say something like, this friend said this about this other friend, click here to see what he said about you. That is just one way in which it is too easy to get someone mad at you. I may have friends I think of as closer than others, but I am never going to tell someone where they rank. :-) So that is my life besides work. Which goes on and is fun. Ciao!

Sam officially graduated. He was second in the line up out of a grand total of eight or nine people. That was a week ago Friday. Sunday we scattered. Sam left for Alaska where he will be working on a fishing boat for the summer. My eldest brother and his wife went back to their house in PA. My second oldest brother went back to his job in Illinois. Dad and my sisters went back to Missouri. Mom went to Birmingham, Alabama where she attended a geneology conference. And I flew back to Boston and took a bus back to Maine. Quite a long trip. I had an hour and a half flight to San Francisco then a three hour layover then a five hour flight to Boston, then a seven hour wait for the bus then a five hour bus ride. Yay! I got back at ten AM the day after I left. This week Anna and Stephanie got back. Stephanie went to visit her brother in Arizona and to drive back with Anna from Texas. They arrived Friday evening. Then yesterday evening the Worship Radio Network helped to sponsor a concert with Joel and Janna, a brother and sister who sing, and Rush of Fools, a Christian worship band from Alabama. It was a good concert. About a hundred and fifty people showed up. Goodbye, goodnight, guten tag, buenos noches, and all the rest.
