Random Linux news

Enough spamming, back to work.

1000

Yesterday I managed to

  • create the 1000th "node" (article) on my homepage/blog/podcast/photoblog at hermann-uwe.de (this includes blog posts, songs posted in the podcast, uploaded photos etc).
  • create a load of >= 1000 on my laptop. I'm not kidding you and this is no typo! The load was higher than 1000, more explanations about how I "achieved" this, maybe even with photos, will follow (screenshots won't work — at a load of 1000 you aren't left with enough CPU time to create screenshots)...

Google Earth for Linux - Beta

OK, so Goole has finally released a first version of Google Earth for Linux (beta, of course).

Well, maybe this time they really mean it when they say "beta"...
Google Earth Linux 1 Google Earth Linux 2 Google Earth Linux 3
Here's some quick observations:

  • Of course, it's not open source, you basically get a bunch of *.so files and an executable.
  • It uses a bunch of open source software packages, though, e.g. libcurl, OpenSSL, libjpeg, libPNG, libtiff, libmng, zlib, Expat XML Parser, FreeImage, and a bunch of other things. All the licenses of those projects are contained in a README, though.
  • The installer seems to be (based on) the Loki installer, at least a ~/.loki directory is created with some stuff in it.
  • The maps cache, and some other files are stored in ~/.googleearth.
  • The ~/.googleearth/crashlogs directory contains log files which are generated when the application crashes, and sent to Google upon the next restart of the application automatically. The README says that you should basically chmod 000 ~/.googleearth/crashlogs if you don't want that. They say these files don't contain personal information. I haven't seen one yet (didn't crash, yet), so I cannot tell if that's true.
  • The EULA says that Google Earth will phone home (they call it "check for available updates to the Software"), and that you automatically agree to that when you use it: "By installing the Software, you agree to automatically request and receive Updates".
  • When I start Google Earth, I get a popup window which tells me to install Bitstream Vera Sans fonts or things might look strange. No idea which fonts extactly they mean, I've got the Debian packages ttf-bitstream-vera, and ttf-dejavu, but the warning still appears.
  • After Google Earth connects to the server(s) I get to see something resembling a globe, but not really what I (or Google possibly) expected. There's simply no textures for anything, I just see (broken) wireframes (see screenshot), but that's about it.

I'll have to play around with it a bit more, maybe it's an issue with the NVIDIA drivers or something. But as I don't have the source I can basically just make stupid guesses...

OS Install Experiences - Part 2: SUSE Linux [Update]

Note: This article is part of my OS Install Experiences series.

Next up: a SUSE 10.1 install. It's been a few years since I touched a SUSE distribution (it was something like SUSE Linux 5.3 or so), a lot has happened since then... Here's a rough sketch of the installation and a few superficial remarks and facts related to security.

Install

  1. First, I downloaded a SUSE 10.1 CD image, burned it on a CD, and booted from that.
  2. The installer that showed up is graphical, and you can choose between a normal installation, booting a rescue system, or running a memory test (uses memtest86, I presume).
  3. While the installer runs it merely shows a rotating logo, but you can switch to other consoles (ALT+F1, ALT+F3, ALT+F4) for watching log messages passing by.
  4. You can choose the language used in the installer, later also your timezone and keyboard layout. You can also check the installation medium, which verifies the checksum of the CD, I guess.
  5. Next, you'll be asked to accept a license agreement (yeeaah, whatever).
  6. Your hardware will be automatically detected (worked quite well for me), and after that you can choose between a new install or a system upgrade.
  7. As for the desktop, you can use GNOME, KDE, text-mode (no desktop), or a "minimal graphical system" (it turns out that means fvwm, at least that's what I think).
  8. The graphical partitioning tool feels a bit awkward at first, I needed several tries until I figured out how to make it use the layout I wanted it to. The default file system suggested by the tool is ReiserFS.
  9. There's an explicit option which lets you choose the default run-level for the system (run-level 5 is pre-configured).
  10. The bootloader, GRUB, recognized the other partitions (Debian stable + unstable), added an entry for SUSE Linux, and created a working setup. Nice, although more control over the process (e.g. naming of the boot options) would be nice.
  11. Reboot.
  12. I'm asked to insert CDs 2 and 3, which I don't have (or want), as I only burned CD 1. Clicking "abort" a few times does the trick, and I can continue by choosing a hostname and domain name for the box (hydra + local.domain).
  13. Now I must enter the root password. Very nice: I have the choice between DES, MD5, or Blowfish (SUSE default) for the hashing/encryption of user passwords.
  14. Afterwards, the network is configured (automatically, via DHCP). You can enable a firewall at this point, and enable/disable access to the ssh port explicitly. It's also possible to enable "VNC remote administration" (default: off), or configure a proxy.
  15. Authentication methods for users, available from the installer: local (/etc/passwd), LDAP, NIS, Windows Domain.
  16. When adding a new user, there are some options. Per default, the user is in the groups "users" (no per-user groups, it seems), "dialout" and "video", but that can be configured. Password expiration is disabled. The default shell is bash.
  17. And now... another registration message (in the release notes, actually). May I quote (from my head): The registration procedure transfers zmd's unique device identifier to Novell's registration web service. The information sent may also include OS, version, architecture, and the output of uname and hwinfo, according to that text. More on that later, maybe...
  18. Of course, SUSE Linux comes with SUSE's/Novell's AppArmor enabled by default, but I haven't looked into it, yet.
  19. Now some problems appeared. More hardware discovery took place, it seems, then the screen turned black (with only a non-blinking cursor in the upper left), no reaction to any input -> I performed a hard reboot.
  20. After booting, I'm dropped into fvwm (although I chose GNOME in the installer), the reason probably being the forced reboot. After looking around a bit in the menus and stuff, I wanted to start sax2 (to find out what it does), but the screen turned black again -> another hard reboot. Could it be that I don't have enough RAM for this (256 MB)?
  21. Anyways, at this point I lost interest in playing with the system any further, and gathered the below information for comparison reasons...

Update 2006-06-05: Added netstat output, and answered a bunch of comments.
Update 2006-06-02: Shortened the length of the article on my main webpage as well as the RSS feed. But you can always read the whole article here, of course.
