Windows 7 installation

I’m an avid user of anything UNIX related: linux, freebsd, opensolaris. I even tinkered around with SCO Unix and Microsoft Xenix (but that was a rather long time ago). But, for some unknown reason I find myself longing to install a windows version.

I’ve used WinXP for a good two months, got fed up that I didn’t get any productivity out of it, and installed a linux distro on my laptop again. Same for the homeserver which was running Win 2003 server at a point in time.

It was that time of year again, so I started installing Windows 7 on the trusty laptop. And all of a sudden it has to go do production within two days of installing. I exploded in an absolute frenzy just to get everything that I might need on the road in there: UMTS connectivity (works), ssh client (two, both work), office (2007, works, duh) (as a sidenote, I love OneNote). And finally to top it all off, a virusscanner/personal firewall thing.

Oi.

It didn’t work, which kind of beta, final release, from whichever firm, it would not work. The resulting install gave me a headache, as the error messages were quite strange. “Unknown error #0x80040201 occurred”. But this night (two days of tinkering and throwing things out of windows and almost throwing in the towel and installing Ubuntu again (I had to become productive again, and secure as well)) I had a light bulb over my head:

Get rid of EFS.

The Encrypting File System (EFS) is a good, sound, well implemented way to have your own files encrypted and no-one will be able to read them, unless you give them permission. Not even SYSTEM can read them.

I’ll repeat that again.

Not even SYSTEM can read them.

If you start a decompression of an EFS encrypted file, the contents will be encrypted as well. In an awful lot of cases this is exactly the behaviour you want. Because you decompress the file, you do not automatically give everyone access to it, now do you? You can do the installation all right (setup.exe does not complain). But SYSTEM cannot read the resulting files. SYSTEM needs to be able to read the files, because they’re drivers, for crying out loud.

If you remove the encryption of the downloaded installer, everything installs fine, like before, but now SYSTEM can read the files. Yay.

Therefore one piece of advice: do not use EFS on your preferred download location, then you can install the resulting stuff to your heart’s delight.

So, I feel quite good about this, now it finally works. I’m running trend micro now, we’ll see if I’ll buy after the trail, or that I’ll be running ubuntu again.

“Slideuments” and bad presentations

I’ve found this article by Garr Reynolds very informative. The article makes a point that the current policies for conferences are putting the audience to sleep, because on the one hand you have to present your presentations for inclusion in the handouts, but on the other hand you have to hold a entertaining and thought-provoking talk that does not put your audience into a coma.

The point he makes are valid, but the effort in making two versions of you presentation can be quite high (I’m not referring to the simple case where an article or thesis is the subject of the presentation). In my humble opinion, it’s quiet unlikely that anyone in the corporate world will allow you to spend twice the time to prepare two versions. However, it’s worth a try…
