Technology Review

I have been reading TR for 6 months - subscribed to Kindle edition. It feels like everlasting chewing-gum - they always write about stem cells, fossil fuels and renewable energy also looks like never-ending story. But from issue to issue - little really new and fresh information is added. There are only few features which tell something really new and interesting - Photo essay (example) (but lack of color makes it much less valuable in Kindle edition) and To Market; it was also a good read about TR50 (50 most innovative companies).

It seems that I would better just follow their website for more frequent updates (rather than 1 issue every two months) and it looks like they still publish some of the articles online for free.

OpenSuSE mirror trouble

At home I use OpenSUSE 11.1. Few days ago I tried to upgrade my VirtualBox from version 2.0 to 2.1.
I ran YAST -> software management, found a new version of VirtualBox in the Virtualization:VirtualBox/openSUSE_11.1 repository. I choose to update the package.
Then I get an error "The file http://download.opensuse.org/repositories/Virtualization:/VirtualBox/openSUSE_11.1/i586/virtualbox-ose-kmp-pae-2.1.0_2.6.27.7_9.1-7.1.i586.rpm is not found on a medium"
I tried this URL with wget and fount that it redirects me to a mirror:

http://77.88.19.74/opensuse/repositories/Virtualization:/VirtualBox/openSUSE_11.1/i586/virtualbox-ose-kmp-pae-2.1.0_2.6.27.7_9.1-7.1.i586.rpm

But, that server gives me an HTTP 404 response.
Then I wrote an email to OpenSuSE ftp admin, he replied that that server (77.88.19.74 (dispenser.yandex.net)) serves the file right to him in Germany.

Then I tried to recieve directory listing from that mirror throug some proxy, the easiest way was to use translate.google.com. And i received the listing.

So, it is for sure now that dispenser.yandex.net filters content for at least ukrainian IP-addresses(as for 2008-01-26). That's not very kind of them(yandex team).

Fortunately, administrators of download.opensuse.org changed configuration to not redirect me to 77.88.19.74 mirror, and now I'm able to get needed files with YAST
