I came across an interesting one in the last few days. This system was a Windows XP system with current updates – SP3, IE 8…. and among other things there was a complaint of very sluggish behavior. I updated the antimalware software installed and ran scans. Malware Bytes antimalware actually found and removed two suspect files, but that didn’t seem to sole the sluggishness. The web browser (internet explorer) would take what seemed like a minute or so to respond to any action. One thing I discovered is that Internet explorer 8 can behave VERY slowly if there are a lot of sites in the restricted zone. (Spybot S&D immunization puts lot’s of sites in restricted zones.) So, I found a way to remove them all and retry and things seemed quicker, but… after running for 15-20 minutes the system really started to become unresponsive and so I had to start looking for another cause…. services.exe was running at 99% cpu or 100% cpu from time to time and the memory footprint was growing – the high mark I saw was 350MB of memory in use for it (!)

Various Notes | Morse Code Ringtones | Java updates | More Pages on the Way
Sorry for the vague title, but there are various thoughts floating around at the moment. The first is a big thanks to the support at Westhost for recovering my VPS over the last weekend. I had started an automatic upgrade of wordpress in one of the sites hosted in this vps, it hung… so I ssh’ed in and found the vps was essentially ruined – it managed to wipe out quite a bit. I’m not sure if it was a coincidence or if the wordpress upgrade was really the culprit, but it managed to destroy quite a bit. The support at westhost though had things back up within 24 hours. It wasn’t just a matter of the site and database getting deleted, but files in /etc were gone (mail configuration hostname resolution wasn’t working, scp wasn’t working…. it was trashed in a bad way.)
Anyway, I’ve still been tinkering with the free morse code mp3 ringtones. In particular I’ve been tinkering with the Text to morse code mp3 generator. I’ve been trying to add utf support. The backend generator does interpret morse for utf characters, I’ve managed to get a way to decode the url encoding if they’re placed in the text box, my big challange at the moment is the file name. I have to truncate the filename so that it’s not too long, but most everything I’ve tried to truncate counts bits instead of characters. Some, even if I tell it to count characters will assume that 1 character=1bit and I wind up with some of the utf characters cut short which gives unusual filename results. In the testing version of the script I’ve just decided to sanitize things by replacing an extended character with an x….

OpenOffice 3 officially released
Good linux format review of the new features and the overall feel (if you can get to it this morning. The main openoffice.org site is down at the moment. New features include a plugin for pdf import, support for the new Microsoft XML docx style file formats (read only). Writer can show several pages at once in the zoomed out view (with editor notes in the margin). Calc can support 4 times the number of columns and has new collaboration features.
Sounds as though it’s a good all around improvement. The speed is about the same as the last version in the 2.x series in their comparison.

Internet Explorer Mandatory Update
Internet Explorer 7 is going to be an automatic upgrade through WSUS (Windows Server Update Services) on February 12. This was announced last fall, but is now about to become reality. According to Microsoft there will no longer be a requirement to prove the copy of Windows installing IE7 is legitimate. Windows Genuine Validation would have prevented the install on copies of Windows that were not officially licensed. Many of those “not officially licensed” copies are pirated, but there have been problems with the reliability of Windows Genuine Validation. Some users have reported legitimate copies of Windows failing the test in the past. So how do you avoid Internet Explorer 7?

Hard drive testing utilities
Windows users know chkdsk, linux users know fsck… users of each MIGHT have heard of SMART. These are different ways of TESTING hard drives. Well, there’s also a utility called TestDisk that looks promising for recovering data… Here’s the clip from their site. “free data recovery software! It was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software, certain types of viruses or human error (such as accidentally deleting a Partition Table). Partition table recovery using TestDisk is really easy.” It runs under a variety of OS’s and recognizes several different disk formats.

X-Plane and linux
I’ve mentioned X-Plane before – it’s a flight simulator that strives to be as accurate flight modeling -wise as possible. Realism is one of their goals and it’s also unique in that it’s available for Mac/Windows and Linux (version 8 that is). (There is flightgear also, but X-Plane has still felt like better competition for Microsoft’s Flight Simulator line.) Anyway… Version 8 had linux support. Version 9 has beta’s out now for Windows and Mac, but there are rumors in the forums that version 9 may not see linux support. (Apparently the person in charge of the linux port has been hired by Google and was working on the linux port in his free time gratis…) I hope we’ll see a version 9 of X-Plane for linux. I wish I could lend help, but bash scripting is pretty much the zenith of my coding skills. (BTW – version 9 LOOKS nice from the screenshots I’ve seen. Here come a few more x-plane related thoughts….

Windows XP repair install problems
I’ve run into a few problems with a windows xp repair install in the last few days that I wanted to detail the problems and what the resolution was. First, it was someone elses laptop needing a hard drive replacement. The drive was imaged, but windows still would not boot, so I broke out the XP Pro disc for a repair installation *(after trying to chkdsk from the recovery console first and fixboot /fixmbr…) Anyway, I went through the repair install process and the system booted up just fine. My next task was windows update and here’s were I started running into problems. Typing an address in the address bar of internet explorer caused a new window to open, which seemed to hang. Opening the home page seemed fine (i.e. the page that loads when you first open explorer), but you couldn’t navigate to another address.

HP Vista CLFS.SYS error
I’ve had a fun time this week dealing with a STRANGE Vista problem on an HP computer (I doubt it’s HP specific, but don’t know for certain.) The error goes like this… “A problem has been detected and Windows has been shut down to prevent damage to your computer.” “CLFS.sys” “Page_Fault_in_nonpaged_area” “If this is the first time you’ve seen this stop error screen….” And the stop error code looks like this “stop 0x00000050” The real problem is everything tried leads to the same place.

Free PDF printers for Windows
I like the PDF file format for so many reasons – free writer under linux is one of them, usually it’s just configured out of the box – openoffice does a nice export to PDF too. Of course, PDF is accessible on all platforms with free viewers…. there are some pdf writers for windows that are free, among them…. PDF Creator and cutepdf also distributes a free pdf writer. Printing to the virtual pdf printer makes archiving web pages fairly easily done as well.

Smartmontools on Windows – emailing warnings
For years I’ve been using smartmontools on my linux-based machines. What I’ve absolutely LOVED about it is the advance notice I’ve had of hard drive failures. Two consecutive Decembers I received an email from my server claiming that a drive was dying and had time to replace them rescuing the data. (Although the first one was falling to pieces as I copied.) If I had not know until I NOTICED a problem I would have likely lost a good amount of data and had a long rebuild process from various backups.
