Some time ago, I’ve talked about chntpasswd as a great utility for when you’re locked out of a Windows 2000 or XP installation because you’ve either forgotten (or weren’t informed) of the valid password to get in. It turns out there is a different approach… well yes, you could format and install from scratch blowing away all data on the drive, OR you could do a second installation in the same partition – that could be messy though and waste space. If you just need a few files off, you could boot up a linux livecd and copy the files to another disc before wiping and rebuilding, but there is yet another possibility….

Brian Krebs highlights a study on data theft/breaches. There are some interesting results (just 1/3 of data breaches were from criminal hacking, 29% from stolen laptops or storage media, 23% from improper disclosure of information (oops I published all our customers information on the website.) and 7% from inside sources – employees taking/selling data, just 2% from lost backup tapes (wouldn’t that fall under storage media?)

The leaders in data loss seem to be Colleges and Universities, followed by the Government and then businesses.

George Ou had a good article on upgrading a laptops wireless to a multiband adapter. It looks like a fairly straightforward process. Personally, I’ve not risked much with regards to laptop repairs. (Keyboard replacement, battery replacement, hard drive replacement and memory have been the typical laptop repairs I’ve done – throw in optical or floppy drive swaps (remember when they had those?) and one or two lcd swaps and that covers 95%+ of what I’ve fixed with regards to laptop hardware.)

There’s a good article at Michael Sutton’s Blog which points out something that really makes sense and I think many people are aware of, but with all the buzz that a new previously undisclosed vulnerability has, we forget. The point is this, there are plenty of machines online vulnerable to ancient flaws that have been known (in some cases for years.) In his article, he does a search for one specific vulnerability and finds targets. Some of the comments speculate that some may be honeypots, but I would doubt that a high percentage are and suspect that most are the real deal.

I just noticed over the weekend that Project Gutenberg has updated their downloadable DVD/CD of free etexts. (Tracker at this link.) The last update of the dvd has been a few years (as far as I can tell (2003?)) It should be noted that you can now create your own image of selected works through a web interface. Given all the hoopla over Google releasing free book downloads, I would have thought that there would be more people reminding us of Project Gutenberg which boasts 19,000 FREE downloadable ebooks (which has been quite a labor intensive process – they’re all in text or html format.)

In the struggle between fairuse4wm and Microsoft DRM, it appears that fairuse4wm is out on top again. Just to sum up – the last few weeks saw a release of fairuse4wm that stripped DRM from Microsoft DRM protected media files, then MS fixed their DRM to break fairuse4wm and now fairuse4wm has released a NEW version that breaks Microsoft’s fix and strips DRM from Microsoft DRM protected media files…. DRM software arms race, kind of fun to watch.

More than once I’ve wished for a second (or third) set of keyboard/mouse/video for my main desktop. Linux is a true multiuser operating system which means that it’s capable of hosting multiple graphical logins at the same time. For MOST things, a single, modern CPU is more than adequate to deal with this (memory is usually the limitation, but 1 GB ought to be enough.) So, I think all of this was prompted by a blurb about hubster which looks like it’s just a VGA-usb adapter. The company that makes it though bill it as a thin client of sorts. So, they’re essentially thinking thin-client over usb as opposed to thin-client over ethernet…

I saw this over the weekend and saw it as marginally more useful than traditional package tracking…. This is called packagemapping.com and is a mashup of package tracking and google maps. I don’t know, I mean, when I read that a package is in Cincinnati, I have a pretty good idea of WHERE that is, Knoxville, etc…. the idea of an RSS feed for your tracking number is interesting – that could be useful. (Although I wonder how quickly that feed would be updated.)

Well, the weekend saw news stories of Google planning to eavesdrop over pc microphones to hear what you’re watching on tv to target ads….. (I’m not holding my breath on that one, but… I do know how to disconnect the microphone.) Also, there was the story of Browzar which was supposedly THE solution for private web browsing…. well, it turns out it set’s it’s own search engine as the default and uses your search information to give sponsored links. Sans also mentions that the last visited url may be saved to disk as well. Really, we have several places where information is kept on us anyway (ISP/etc.) But, if you’re really concerned about private browsing you might try out the vmware browser virtual machine (or a portable web browser on a usb-key.)

After 12 years of effort FreeDos has reached the milestone 1.0 released. It can be found here. I’ve really found freedos to be quite usable for quite some time as a drop in replacement of MS Dos environments. I’m struggling to remember any dos-based prorams that it wouldn’t run well. *(Possibly some games?)
