A few weeks ago we traveled a bit west and visited the Yellowstone and Grand Teton National Parks, I’ve finally gotten around to sorting through the pictures and uploading a few (well, actually a lot).
[album id=28 template=dopefish]
I didn’t get around to editing and stitching the panorama photos together yet, or doing anything interesting with the GPS data of our hikes yet. If I get that done I’ll probably update this posting.
Searching for a linux command line rcon tool can be a bit of a pain: dead links, outdated versions not working anymore, stuff written in php …. yeah. The only version I could find was stuck in a cache of an old webpage. So here is my mirror of the http://www.asyserver.com/~cstrike/rcon.c file that currently gives you a “404, File not found” error. Hopefully this will help anyone trying to find a working version via google and is frustrated with the results. Download, compile, happiness ensured.

Warning: this is mainly me just ranting about Microsoft stupidity and a warning for anyone using junctions.
About a month or two ago I built myself a new PC (old one was dying) and installed Win7 on it. Since I was previously still on WinXP there were a few things to get used to, but all in all I enjoyed the update. There were of course some strange Windows pitfalls involved, moving your users directory to a different drive really isn’t straightforward, but works if you use junctions to link the directories.
Since Virtualbox drops the guests in a subfolder of the users directory I decided to move my users directory to one of the larger mechanical disks in my system, to keep the windows drive (a SSD disk) with plenty of space.
Now fast forward to yesterday, where some software I installed decided to clear out most of my Start->All Programs folder, leaving me with lots of installed softawre, and no Start Menu links. After trying some stuff out I finally caved in and used System Restore to get my Start Menu working again. System Restore actually worked fine, I got my Start Menu back … unfortunately it also corrupted my profile, and while googling to find out how to fix it I found a whole lot of people with the same problem.
Junction + User directory + System Restore = corrupt user, non repairable. Hello Microsoft, this is all original system software, no 3rd party stuff, breaking my user is totally uncool.
So after trying all kinds of crazy tips I found I gave up and followed the official instructions (a.k.a. You are fucked, haha bye bye user registry). And right now I am copying stuff from my old profile to my new one and setting up all the software that had stored stuff in the registry. This time my Profile stays on C: without any junctions, it’s easier to repair Virtualbox if it breaks over the images being in a non-standard path than worrying about windows corrupting my whole profile if I touch System Restore.
Monday we headed over to St. Anthony Falls here in Minneapolis (Mississippi river). There is a Heritage Trail around the falls that gives you a nice view of the falls and surroundings.

Anyone from Europe will tell you that what Americans generally consider “bread” is more like a loaf of bland nothingness with the consistency of a sponge that can be mushed together into something resembling playdough. To be fair, it is okay if you get some multigrain bread and toast it to give it some firmness and make sandwiches, but other than that ….
Artisan bread is a step up and brings a bit more taste and firmness. It can be found at various stores, we generally get some from Cub or Trader Joes. But the best bread we have found till now is at a local “breadsmith” here in Minneapolis / St. Paul. They truely sell real bread. Yaaaay. So if there is a breadsmith near you, drop in and have a look, might be you find bread like you have never tasted before.
