			<content:encoded><![CDATA[<p><a href="http://wensblog.com/wp-content/uploads/2010/03/belt-cp-v2-red-big.jpg" rel="lightbox[304]"><img class="alignleft size-full wp-image-303" title="belt-cp-v2-red-big" src="http://wensblog.com/wp-content/uploads/2010/03/belt-cp-v2-red-big.jpg" alt="" width="630" height="385" /></a>The other day in the office I heard wat sounded like the drill of a dentist.  I looked behind a wall and saw a very small helicopter flying around. It was about the size of one of those big Southern European dragon flies. I started talking to the guy flying it. After a while I played around with it a bit too and had a lot of fun.</p>
<p>A week or so earlier at a birthday party someone gave a bigger helicopter which looked very nice as a present. So by the time I was flying that bug I was pretty much ready to get my own helicopter. So I stared looking around.</p>
<p>First of all I was surprised to see what a wide range of products are available when you started looking for a remote controlled helicopter. You can get cheap small ones for as little as 30 euros and the big ones with flight models that are quite realistic go up to thousands of euros.</p>
<p>I ran into the Esky Belt CP V2 and it seems to be a sophisticated machine for a reasonable price. I bought it a few days later and picked it up at the &#8216;shop&#8217;. Shop is a big word as the guy sells these helicopters as a hobby from his garden shed. He was very nice though and showed me the basics and told me how to start it properly. So I went home and tried it out.</p>
<p>Charging the battery takes three hours. That&#8217;s quite a bit, but then it&#8217;s a powerful battery. That big battery only allows for about 10 minutes of flight though. After those ten minutes you&#8217;re back to waiting for 3 horus before you can have a go again. So of course I pretty soon ordered a second battery.</p>
<p>The first couple of times I was very careful. When that gave me mixed results I became a little less careful. That seemed to go well for a while, but then disaster struck. It went sideways and instead of powering down, I powered up by accident. It accelerated sideways and banged into a chair&#8230; The blades shattered at the tips and the helicopter came to a halt on its side&#8230;</p>
<p>So I ordered two sets of blades too. They don&#8217;t cost too much, so it&#8217;s not that bad. I just hope I didn&#8217;t damage any other parts of the helicopter. There&#8217;s a reason spare parts are so readily available&#8230; People crash them regularly when they&#8217;re still learning to fly</p>

			<content:encoded><![CDATA[<p>A short while ago I started having issues with the third bay in my Synology DS408, after already having had too many issues with bay 2. The bay was empty according to the NAS. Two bays with issues, about time to look for help. I posted a few lines on the Synology forum and the same day someone told me to send in a kernel log.</p>
<p>I did this and a day later I got a mail. The support guys at Synology think it&#8217;s an issue with the SATA cables. This seemed improbable to me as it would mean that I have two broken SATA cables. But after googling the issue I must say Synology could be right.</p>
<p>Lets hope the replacement cables come soon. Then we can see if they fix the problems.</p>

			<content:encoded><![CDATA[<p>Apple today released a patch for the Nehalem-based Mac Pro issue concerning heat and temperature rises when playing audio. The fix can be found <a href="http://support.apple.com/kb/DL1004" target="_blank">here</a>, but it can also be obtained through the regular software update process.</p>
<p>First tests confirm that the issue has been resolved. After installing the patch the temperarture of the processor didn&#8217;t rise when I started playing music in iTunes. The processor also uses just 5 watss after starting to play music, instead of the 100+ watts before the patch.</p>
<p>I think we can thank the people who made a lot of noise on forums and the tech sites who wrote about this issue for bringing the urgent need for a fix to Apple&#8217;s attention.</p>

			<content:encoded><![CDATA[<p>A lot of people were hoping for new MacBook Pro models at the last Apple event, but it was all about the iPad.  It&#8217;s about time Apple upgrades their laptops as most brands are now offering laptops with the new Intel Core family processors. There is a rumor that Apple will upgrade their laptops today. <a href="http://forums.macrumors.com/" target="_blank">MacRumors</a> is writing about <a href="http://www.macrumors.com/2010/02/08/current-macbook-pro-models-deleted-from-best-buys-inventory-system-updates-imminent/" target="_blank">it</a>.</p>
<p>Personally I&#8217;m hoping for an upgrade for the MacBook Air. I don&#8217;t need it to have more processing power, but it could do with a little more memory. These days 2 Gigabytes isn&#8217;t that much when you consider part of that memory is used as memory for the graphics card.</p>

			<content:encoded><![CDATA[<p>It seems the 2009 Mac Pro has an issue. When it idles, the processor temperature is about 35 C (95 F). When you play music in iTunes or any other application, the temperature rises to 50 C (122 F) or even much higher in a short amount of time. I read about the issue on MacRumors (article <a href="http://www.macrumors.com/2010/02/03/audio-processing-causing-heat-and-performance-issues-for-nehalem-mac-pros/" target="_blank">here</a>) and and in a discussion on the same site <a href="http://forums.macrumors.com/showthread.php?t=795966" target="_blank">here</a>.</p>
<p>I have a late 2009 Mac Pro and I have tried to reproduce the issue. All I had to do to succeed in this was play a song in iTunes and within half a minute the temperature of the processor of my Mac Pro (a 2.66Ghz quad core) had risen by 15 degrees Celcius. That&#8217;s 27 degrees Fahrenheit. Rather silly when you think playing audio is a simple task for a fast processor like this Nehalem.</p>
<p>In discussions I&#8217;ve read the issue doesn&#8217;t exist when running Windows on the Mac Pro. This makes me think it&#8217;s a software issue. Well, at least software glitches can be easily fixed. Let&#8217;s hope Apple takes this issue seriously. So far they haven&#8217;t acknowledged it.</p>

			<content:encoded><![CDATA[<p>A month or so ago I booted my Mac and noticed that I didn&#8217;t see my NAS (the Synology DS408 I mentioned earlier) in the Finder. I had a look at the status lights and noticed the drive light of the second drive was blinking irregularly as if it was reading or writing data. It wasn&#8217;t possible to SSH into the machine anymore. I tried to restart it with the power button, but that didn&#8217;t seem to have an effect. It only started blinking and then nothing happened. In the end I pulled the plug and let it sit there for a while.</p>
<p>Later I tried to turn it on again, but it didn&#8217;t seem to want to boot after pressing the power button. I took the electricity off again and a few minutes later turned it on again. It did boot that time, but drive 2 seemed to be dead. The NAS beeped loudly to show its discomfort. I shut it down again, took drive 2 out and put it back in. Somehow the drive came back to life again and I could rebuild the RAID configuration.</p>
<p>But I was not comfortable with the situation. Why did the drive fail in the first place? Did it fail? Was it a loose connector? Or did the NAS malfunction? Oh well, the feeling of discomfort slowly disappeared with time as the NAS kept performing nicely.</p>
<p>Last week it happened again&#8230; Drive 2 failed. I bought a new 2 TB Hitachi DeskStar drive and replaced drive 2. Time will tell what will happen. Will this drive fail too?</p>
<p>So far I have observed it runs a bit hotter than the 1 TB drives in the nas.</p>
<p>I chose a 2TB drive because I am going to replace the other drives with 2 TB drives too.</p>

			<content:encoded><![CDATA[<p>After I got my new computer I turned my old desktop into a host for virtual machines. At first I tried KVM under Ubuntu, but I didn&#8217;t get it to run smoothly. I then found out that VMware has a free version of their ESXi hypervisor platform.</p>
<p>The hypervisor seems to be free, but the software to manage it is sort of free. I haven&#8217;t been able to put in the serial key yet, but I must say the way it runs now is impressive. I&#8217;ve got three virtual ubuntu servers running on my old 2.4 GHz core 2 duo with 4GB of ram. It all runs smoothly. I do see some slowdowns, but it&#8217;s ok. The graphical client software (Windows only unfortunately) is very elaborate and offers a lot of functionality.</p>
<p>I&#8217;m still trying to find out though if I can stick to ESXi once the 60 day trial period runs out or if it just becomes unmanageable. So far I&#8217;m not sure. Anybody got any idea what I&#8217;ll miss then?</p>

			<content:encoded><![CDATA[<p>Three weeks away from home means that on return you&#8217;re confronted with software and firmware upgrades for just about every piece of software and hardware you have lying around the house.</p>
<p>This blog had to go through 6 upgrades. The other blog will have the same amount. My Mac went through three. My Ubuntu laptop is complaining and I haven&#8217;t even dared to boot my work laptop. My phone wanted to be upgraded too. Not just it&#8217;s OS, but about ten pieces of software on it too.</p>
<p>I&#8217;m starting to feel I am serving the machines instead of they me&#8230;.</p>
