			<content:encoded><![CDATA[<p>VA recently changed over to a new <a href="http://www.dmv.state.va.us/webdoc/general/news/dlci.asp">secure drivers</a> license, so instead of printing them in the DMZ office, they just take your photo and then mail you the new card. So my drivers license is now a letter sized piece of paper until the new card gets mailed to me. </p>
<p>So I have some issues with this, first lets look at the practical side of this. I now have to carry a piece of paper with me when I drive. The letter sized paper doesn&#8217;t fit in my wallet. I could leave it in my car, but I don&#8217;t always drive the same car. Someone during this process must have thought, man that&#8217;s going to be a pain, lets give them something that will go in their wallet? Now here is the strange thing I know they can do it, when I did a change of address a couple years back I got a card that you could cut it down so it fit in your wallet, and carry with your drivers license.</p>
<p>Then I look at the reason they are going to the new secure printing center, they are doing it in the name of security, that might be all great, and the new card may be more secure, but as part of that they have now introduced a new proof of drivers license that is, 1) printed on normal paper, 2) has my signature, 3) has a rubber stamp on it saying paid, the date, and 6 character identification number on it, and thats it. It wouldn&#8217;t be very hard to make a fake version of it. So on one hand you have a nice secure card, on the other you have a piece of paper. So which do you think the forgers are going to copy? The only compensating control is that all the local cops have computers in their car so they can look up the license information, that might bring up my photo as well, but what happens when you are in  a dead zone or in a different state, you are now back to proving a piece of paper is really a drivers license.</p>
<p>Finally, what is going to happen when I fly or go drinking. They are going to take one look at my expired license and tell me it is expired, I highly doubt they are going to going to accept a piece of paper as proof that it isn&#8217;t really expired, and I am just waiting on a new one.  </p>

			<content:encoded><![CDATA[<p>Why change something thing when it aint broke?</p>
<p>I used to be able to run vmware-cmd to start and stop vmware server 1.0 vm&#8217;s from the command line it was a simple sort of.</p>
<p><code>bash# vmware-cmd /usr/local/vm/vm/vm.vmx start</code></p>
<p>Now is Vmware Server 2.0 I have to do</p>
<p><code>vmrun -p [password] -u [username] -T server -h https://localhost:8333/sdk start "[storage] vm/vm.vmx"</code></p>
<p>simple right? oh and you are forced to put your password in the command line which will be saved in bash history and to anyone who can run <code>ps</code> on the sever. I was really hoping that it would follow the mysql convention and prompt for a password, but I guess not</p>
<p>Thanks for the upgrade VMware, you just made the world less secure.</p>

			<content:encoded><![CDATA[<p>I read today that metro is <a href="http://www.washingtonpost.com/wp-dyn/content/article/2008/10/27/AR2008102700767.html?nav=rss_metro">starting to do random bag searches</a>, this reminds me of my recent trip to Beijing where all bags had to be x-rayed before being allowed onto the station platform. I am not sure what they were looking for but they weren&#8217;t looking very hard. I don&#8217;t think I ever saw anybody getting a secondary bag search.</p>
<p>I doubt that this will add much to the safety on the metro other than to generally slow everyone down. <a href="http://www.schneier.com/blog/">Bruce</a> will probably comment about on this as part blog postings on security theatre and the <a href="http://www.schneier.com/blog/archives/2008/10/kip_hawley_resp.html">TSA</a> and their security procedures. At least they are going to have a bomb sniffing dog so that they are one step above the useless checks at the Smithsonian Museums.</p>

			<content:encoded><![CDATA[<p>So I noticed another of my ubuntu boxes was running slow so I did a </p>
<p><code>Host:~$ sudo hdparm -t /dev/sda</p>
<p>/dev/sda:<br />
 Timing buffered disk reads:    8 MB in  3.72 seconds =   2.15 MB/sec<br />
</code></p>
<p>so it looks like it has the same issue as my<a href="http://www.imacdonald.co.uk/2008/08/01/sometimes-you-got-ot-hate-linux/"> other machine</a></p>
<p>so I did<br />
<code>Host:~$ sudo lspci |grep -i ide<br />
00:0f.1 IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 06)<br />
Host:~$ lsmod |grep -i ^libata<br />
libata                159344  4 pata_acpi,pata_via,ata_generic,sata_via</code></p>
<p>and added the following to /etc/modprobe.d/blacklist</p>
<p><code>blacklist ata_generic<br />
</code></p>
<p>and the following to /etc/initramfs-tools/modules</p>
<p><code>pata_via<br />
blacklist ata_generic</code></p>
<p>then rebuild initramfs</p>
<p><code><br />
sudo update-initramfs -u -v<br />
</code></p>
<p>After a reboot I now get </p>
<p><code>sudo hdparm -t /dev/sda</p>
<p>/dev/sda:<br />
 Timing buffered disk reads:  164 MB in  3.02 seconds =  54.38 MB/sec<br />
</code></p>
<p>Amazing what this little tweak will do for performance.</p>

			<content:encoded><![CDATA[<p>I think I may have just resolved the abusive phone calls I have been receiving from blocked caller id and caller id from 0000123456. Jerimia just called from National Financial Systems looking for Frank Edison. He was polite enough to tell me the company he worked for and that their telephone number is 1 800 765 4733. I then explained to him that I did not know Frank and I have had my cellphone number for about 6 years now. He noted that after each call my number had been marked for removal but then went back in the system. He also identified himself as a supervisor so I let him know that I had repeatedly ask to have my number removed and that when I was called at 9:15am on Wednesday that  I asked to speak to a supervisor and the caller refused. He said that this was not the way National Financial systems operates, but it seems they have a <a href="http://www.ftc.gov/opa/1999/12/natfinsys.shtm">history</a> of <a href="http://www.budhibbs.com/debtcollectorpages/national_financial_systems_bud.htm">doing</a> this <a href="http://www.ripoffreport.com/reports/0/228/RipOff0228973.htm">kind</a> of thing. I haven&#8217;t decided if I will file a complaint with the FTC yet.</p>

			<content:encoded><![CDATA[<p>I should do some more reading on this, but I am amused by the <a href="http://www.us-cert.gov/current/index.html#clamav_pe_scanning_vulnerability">US Cert</a> comment at the end</p>
<blockquote><p>ClamAV PE Scanning Vulnerability<br />
added April 14, 2008 at 09:21 am</p>
<p>US-CERT is aware of a report of a buffer overflow vulnerability affecting ClamAV. This heap-based buffer overflow vulnerablity may allow an attacker to execute arbitrary code on an affected system.</p>
<p><em>US-CERT recommends that users do not scan PE files from untrusted sources.</em>
</p></blockquote>
<p>Isn&#8217;t the hole point of running an av product to test for viruses in untrusted files?</p>
