I have heard some rumors that Windows Vista had a good screen capture tool built into the operating system itself. So when I needed to do some capturing on my home machine, I started looking for it. Turned out that it is an optional install on certain versions of Vista only, but Home Premium is one of those versions. The tool is called “Snipping Tool” in English versions, or “Skärmklippsverktyget” in Swedish versions.

I just got myself a new home PC, to replace my no longer very trusty five-year old Athlon-based PC. In the process, I realized I had to move my iTunes library from the old machine to the new. Reading on the web and the Apple support area made me somewhat skeptical as to the feasibility of this operation… would all my cover art, podcast subscriptions, playlists and ratings survive the move? There are many stories of failed moves and lost data out there… and moving from Windows XP to Vista 64-bit did not make the dread less.
In the end, it turned out it was really dead easy!

This is really quite funny: it is now twice that slightly panicked family members have called me to ask how to rotate the screen in Windows XP back to normal after toddlers of about six to eight months of age have managed to rotate it to 90 degrees or upside down by just banging on the keyboards of their computers, as small children tend to do.

It is a symptom of bad UI design when things just happen, and you have no why, and no visible indication to help you figure it out. Last night, I noted that the text in Outlook when composing email suddenly was way larger than normal. I put that way as a fluke, but today, the effect was still there, all the time. Strange. So I went in and checked my font settings, which were all fine. This being Office 2007, I suspected some kind of zoom effect, but there was no zoom indicator in any Outlook window. I tried ctrl-+ and ctrl– to see if Outlook respected the web-style view size shortcuts. But no effect.
Sometimes you find this rare gem of a piece of software that just works and that just solves a problem you have been having an itch with for a long time. SnagIT, from TechSmith, is just such a program. It makes doing screen captures and editing them incredibly easy and convenient. It also has some nice extras, like capturing a webpage in its entirety by scrolling the window in Internet Explorer or Firefox. Simple, but a great time saver for me. I feel like I literally saved hours of work time in just a few weeks of using this program. 30 bucks for a piece of software that does screen capture? In my job, a no-brainer. Highly recommended!
I just found out that my favorite Windows XP PowerToy is built into Windows Vista. To get to a command-prompt located in any folder directly from the Explorer, follow the instructions found at a Microsoft MSDN blog: Tim Sneath : Windows Vista Secret #1: Open Command Prompt Here. Very useful. But why not make it more obvious than “press shift while right-clicking?”.
Vista just gave me an interesting error message: running a serious Java program required it to turn off the Aero interface. Interesting. What can Java have done to deserve that?
One common use-case for multicore processing on the desktop and elsewhere is “doing many things at the same time”. You could be running many user-interface programs at once, like the “typical today’s teenager template” of tens of IM clients, web sessions, email conversations, music and video players, downloading movies, etc. Or it is a more business-like background indexing of harddrives, backups being taken, downloading large business files, compiling software, updating source code repositories, etc.
I have been doing both of these modes to some extent, and the main problem with them at least on a PC is that while the processors might be good at multitasking and sharing the CPU load, my IO system is annoyingly non-parallel.
A company called Fastscale Technologies has a product that is simple in concept and yet very powerful. Instead of using complete installs of heavy operating systems like Linux or Windows to run applications on virtual machines, they offer tools that provide minimal operating system configurations that are tailored to the needs of a particular application. Since only that application is going to be run on the virtual machine, this is sufficient. According to press reports, this means that you can run several times more virtual machines on a given host, compared to default OS installs. And boot an order of a magnitude faster.
