VirtualBox is a virtual server environment similar to that of VMWare. Due to hardware compatibility I am using VirtualBox on a server instead of the recently released for free ESXi. Enough gibber jabber, on with how to get it up and running.

Step 1. Install CentOS onto your server. You can download the CD images or DVD images from their site. CentOS is pretty much Redhat Linux without the licensing and corporate support.

Step 2. Update your server. Once your machine is up and running do the following steps to prepare for the installation of VirtualBox onto the server. Depending on which options you chose during install, you may not need to perform some of these steps.

  1. yum update
  2. yum install  SDL
  3. yum install kernel-devel
  4. yum install gcc g++

Step 3. Downlaod VirtualBox from their website. This is to get the non-OSS version, which in my opinion has better features/options. Choose the one for RedHat, and place it on the server.

Step 4. Install VirtualBox.

rpm -ivh VirtualBox-2.1.4_42893_rhel5-1.x86_64.rpm

This is technically all you have to do to run VirtualBox on your server. The next question is whether you want to run it as root or as a nonpriveleged user. Out of general good practices, it is important

Step 5. Add your user to the vbox group. This will allow you to run VirtualBox as a user without the potential for Virtual box to destroy your machine. Not likely, but possible.

Step 6. Run virtual box. Provided that the executable is in your path all you should have to do is run the VirtualBox command. This will bring forth the gui.

VirtualBox

Enjoy!

I have an e1505 Dell laptop that I bought a February of last year. At the time, I had been considering a mac, but due to pricing and other reasons, I ended up getting the Dell. Overall, the system was fine, and I ran both Linux and Windows on it. That was until about 3 weeks ago.

About 3 weeks ago I started having problems with my battery running down quickly, and then about 2 weeks ago it would not take a charge. Being busy, I did not end up calling Dell support until yesterday. Getting through to support was quick and easy, and it was a pleasure getting to talk to someone from the Philippines. To bad all the news/information that she had for me was just horrid.

Turns out the battery that comes with the Dell e1505 has a working life of approximately 1 year. Does not matter if you charge it and run it down all the time, leave it plugged in, or just use it every now and then. The life of the battery is 1 year. That is just stupid.

I have had other laptops, and at about the 3 year mark I would start to have issues with the battery. I can accept that, and if the laptop is still working OK, then I might invest in a new battery over a new laptop. But to find out that I will have to replace the battery every year is just outrageous. Oh, and the cost of the battery? The 9 cell is $155 and the 6 cell was $135. For the price I would have to pay every year, I would have been better off paying the Apple tax.

Just to compare, my no name laptop went 3 years before the battery started to fail, old macbook pro went 4 years, and numerous work laptops went 2+ years. Now at 1 year 3 or 4 months I have a battery that has to be replaced. WHAT A RIP-OFF!

Not sure what I am going to do now, but I do not want to give Dell any more money, and I will never buy a product from Dell again that is for personal use.

On May 2nd, Dirty Spokes, held their second of four endurance mountain bike races at Ft Yargo park in Winder, GA. The event was a mixed 6/12 hour race with teams of 4 all the way down to solo riders in it for 12 hours with classes for coed teams, single speed, Clydesdale, beginner, sport, and expert.

The day before race day people on the forum were stating that the trail was a bit dusty, and that it could use a bit of rain to help it out. Well, that night it rained buckets. I live 20 minutes away, and it came down for a good couple of hours where I live. Needless to say, while Yargo drains well, none of the parks around here drain that well. The forecast for race day was 40% chance of showers in the afternoon. Only time would tell.

This was my third race, and I tried to prepare for it as well as possible. In retrospect, I still think that I need to refine this process. I am sure that it is just something that is going to take time to get down. First off, get a good bag. One that does not flop on itself when it is not full, and one that has a number of pockets. I think this is one of the things that probably caused me the most grief, rummaging through my bag looking for things.

Another way to prepare is to set all your stuff aside, and pack it the night before the race. For this I would recommend a checklist. Seems like I always forget something on race day. Organization is the way to go. Get any tools you need together. Determine what you are going to take on the course with you, and set it all up. If you are riding with a camel back or similar, load it up with spare tube, chain links, multi-tool, etc. This will make life easier on race day. Don’t forget to make sure you have done any work on your bike that you need to, and that you have test road it.

On race day I got up early, had my coffee and breakfast. Looked like a beautiful day for a race. The weather was great. Loaded up the vehicle and headed over to Ft. Yargo. Got there around 7:30, checked in, and then found where the rest of the Gwinnett Area Trail Riders (GATR) had set up. I started to carry my stuff up to the tent that Trunk Monkey had setup the night before. It was then I realized I forgot my chair, and that my duffel bag needs to be replaced. Also realized that I had not loaded up my camel back with all the essentials. (When will I ever learn).

Pre-race was fun. Hung out with the GATRs. Got to meet a few more that I had not met before, and just enjoyed the mood. Bathrooms were flooded with people. Two stalls and two urinals is just not enough. It would also be nice if people could figure out how to drop a load without stopping up a toilet. Maybe their parents didn’t teach them, or they just have out houses at home. It was then time for the mandatory meeting, which covered the general rules.

Starting line. I am still working on my stamina and speed, and as a result I took a place in the latter half of the starting line-up. To be honest, I think that I picked a good position. Could have moved up just a bit, but anymore than that and I would have been kicked in the arse for going too slow. The parade lap gave a slight indication as to how muddy some of the trail was going to be, but it looked like things might be ok if the weather held. I also think that I should have done a warm up lap. My muscles take a moment to get going.

The first lap was not to bad. After the crowd thinned out I managed to pass a few people, and thought that my pacing was not bad. I knew that there was no way I was going to get on a podium, but I just wanted to improve upon my last performance. My bike was responding great, and I was feeling good. Finished the first lap in about 1:30. I pitted to stock up on fluids (at this point I was already not drinking enough) and to eat a pickle.

With that I headed out on my second lap. Shortly into my second lap, I noticed that my seat seemed to be slipping. I have had this problem before with this seatpost, so I tried to tighten it down just a bit. On mile marker 5 I tried to tighten it down, and managed to break my seatpost clamp. The next 7 miles were ridden with my knees in my chest. On the hill climb I cramped pretty bad, probably from not drinking enough water. Finished out the lap in under 2 hours. It was also on this lap that the skys decided to open up and we had a deluge of rain, thunder, and lighting. The trail looked like a creek in some spots.

Neutral support was great. The tried to fix the clamp, and when that failed, found a clamp off of another bike and put it on mine for $5. Could not go wrong with that. I also realized that my seatpost was bent. That is what I get for riding a hardtail and weighing 205lbs. It was then that I knew I was not going to be able to finish 4 laps. So my goal changed to 3.

My legs were already tired from the saddle position the lap before, but I still wanted to get in three laps, so I headed out. From the beginning I could tell that my heart was not in it. My legs were spent, and I could not force myself to get moving. At one road crossing I stopped for a few minutes and seriously thought about calling it quits for the day. Bob came by and yelled something about needing to be moving. I decided I was going to finish it and got up.

Somehow I got to the last 3 miles when I realized that I had under 20 minutes to spare to finish the lap. The trail was so bad that my front derailleur was not working, and the rear was so-so. Calling a line from “The Blood of Heroes” I summoned the resolve to finish in time. Trunk Monkey passed me, and about 1/2 mile later my leg started to cramp again. I fought it off, got back on my bike and kept riding.

When I crossed the last road to the last 1/4 to 1/2 power-line run to the finish line I asked the guy how much time we had left. He said it was 4:00 pm by his watch. No way, that is when the race is supposed to end for the 6 hour riders. I said we should have at least 2 minutes. He said he wasn’t sure.

The guy in front of me heard it and headed out, and I followed suit. Nearly clipped a tree getting to the mud pit open grass track to the finish, but kept it upright. I gave all I had coming into the finish. It felt great to see people up there cheering you on to the end. I crossed the line to find that I had 1:30 left on the clock. Felt like I was going to puke, but great all the same.

That last lap took almost 2:30 minutes, but was well worth it. I would have liked to stayed and cheered on the rest of the riders, but I had to head on out to my daughter’s ballet recital. Props to all the riders that passed me, include the rest of the GATRs.

Next year, 4 laps.

The Sette Reken frame is a hardtail frame that is available through Pricepoint, an online bike and parts retailer. The bike comes in one colour, Matte Black, and four sizes: 14″, 16″, 18″, and 20″. It is only available online, and is marketed as a Mountain frame versus an XC (Cross Country Frame). It has an MSRP of $250, but sells for $99. It is made of 6061 T6 aluminum, and the given weight of the 18″ model is 4.5 lbs. It comes with mounts for both disc and caliper brakes, has a removable rear deraileur hanger, and comes with a quick release seatpost clamp.

I am 6′ 4″ and ordered an 20″ for my testing/use. From my research, it looks as if the bike has very similar geometry to that of the Specialized StumpJumper with the sizes of the Stumpjumper being 1 inch smaller than that of the Reken. Most bike shop owners recommend that I ride an XL bike, but years of BMX have me never wanting to set foot on an XL bike again. This frame was to be used as my primary bike frame as I was replacing my 2008 Gary Fisher Marlin with the Sette Reken. I purchased the bike through Pricepoint just like any other customer, and did not recieve any special discount or promotions for doing this review. (Just wanted to state this because I sometimes wonder about people that demo “free or loner” bikes.)

Initial opinion. The Reken frame showed up 3 – 4 days after ordering it from Pricepoint. The box was big and had a stamp on it that said made in china, if I remember correctly. Inside the box was the frame, which was packed quite nicely, and the deraileur hanger and cable clips were in a secondary bag. Pulling it out and holding it up I was not sure if it would last one ride. The frame felt light. To be honest though, it is not as if I have a ton of experience looking at frames without all the parts put on them. The paint job was fine and I did not see any cosmetic blemishes or construction issues. The tubes on the Sette Reken are straight, and not hydroformed, but other than that, I was happy with what I had gotten for the price.

The build out. I took the frame to a local bike shop to have the headset, bottom bracket, and crank installed. They chased the threads (helps to ensure proper install of bottom bracket) and installed the components without issue. In fact, the shop guy was impressed with the frame, and mentioned purchasing one for a hardtail he was considering building out. The rest of the components I moved over from my old ride when possible, and new parts where needed. It was my first time running cables, and it took me 2 days and about 4 hours to get it right. Once it was done though, it looked sweet and I could not wait to take it for a spin.

At one point, I had posted my initial thoughts on this frame, and now that I have had the Reken for a few months and have several rides on it under my belt, I am ready to give a full review of how the bike rides. To ensure that I was getting the test out of the frame I rode the bike with the fork locked out and with the fork set regular. Also, I rode trails that I am familar with, and that I know how they have handled for me in the past. Based on this my findings are as follows.

For a sub $100 frame, the Sette Reken rocks. I have read reviews on MTBR.com about the Reken, and was not sure if it was hype from people at Sette or Pricepoint. After riding on this frame, I have to say that those reviews are from real people. I said earlier that the Reken frame has similar geomety to that of the Specialized Stumpjumper. To that note, it acts like it is a Stumpjumper. The handling in turns is nimble and responsive. The “flickability” of the bike cannot be beat. At high speeds the bike remains stable, and it is not jittery at low speeds. When it comes to climbing the Sette Reken is as solid is you could hope for. The Reken climbs like a billy goat on crack. (Not the best comparison, but apt) Best of all, the bike just feels good under you.

My overall opinion is that you cannot go wrong with the Sette Reken frame. It has a 5 year manufacturers warranty, but even if it only lasted a single year, it would still be worth every penny that it cost to purchase it. You may not be supporting your LBS (local bike shop) when you buy this frame, but on the other hand, you are not doling out $600 or more on a name brand frame. That means that you can put your money into other upgrades like your fork, wheel set, or cranks. This frame gets 5 stars from me, and is one that I will recommend to other riders that are looking at doing a custom build or just moving parts off of an old or broken frame.

Why is it that download speeds from one location to another vary so much? Wait, before you answer that question, let it be known that I understand the routers, switches, hops, pipe size, and all that funky stuff. I am talking about downloading content from certain areas around the globe.

To start, let me set my location. Otherwise, this entire discussion will be a waste of time. I live in the South Eastern United States of America, in a burb located outside of Atlanta. Say what you may, but I like Georgia. As a self proclaimed Computer and Linux Geek, I am always trying out new software, and often operating systems. The strange results that I get, are when I am attempting to download various programs and/or operating systems to test/use.

This only works when you can choose the location of your download. Otherwise, it is up to fate/chance/luck/karma to determine where your file will come from and the speed of the download. But, if you have a choice of where to pull from, generally with location and server information, then you can find some strange results. For instance, I try to avoid downloading files from servers that are anywhere in the U.S. of A. other than the south east. It has been my experience, that most U.S. servers, even those in the south, are slow. I am not 100% sure why, only that after doing this for years, the results are similar time and time again.

So where do I get my files from? Europe. Crazy? I know. It first happened years ago when I was downloading a couple gig file from a local server in the states. Time to download was around 2 days. As a result, I started to try different servers in the U.S. No luck. A few were slightly faster, but all of them were pathetically slow. It made me wonder if there was a problem with my connection. On a whim, I decided to try a server from the Netherlands, (I have always wanted to go there), and surprise surprise, I am pulling down the file at 4 – 5 times faster than any server in the U.S.

My first thought was that it was a fluke, and it had to deal with the time of day or some other reason. Yet as time has worn on, I have continued to find that I get repeatably faster connection/download speeds when connecting to europe. This is not to say that they are all faster. Some countries tend to have better response times than others, and the ones that I go to have the best track record over time. It does not matter the time of day, day of the week, or any other variables that I have tried to throw at it. All I know is that it is faster, and I hope it stays this way.

The next time that you go to download a file keep this in mind. That initial server you connected to at 60 – 120k/sec may seem fast, but it is all relative. Try some other servers and other locations. I would be interested in knowing what your experiences are, and where you are located. Maybe a trend could be found based on locations. Or maybe it is all in my head. Either way it would be interesting to know.
