From pgunn at cs.cmu.edu Mon Oct 13 12:35:04 2003 From: pgunn at cs.cmu.edu (Pat Gunn) Date: Mon, 13 Oct 2003 12:35:04 -0400 (EDT) Subject: [auton-users] USB Keychains Message-ID: Hey all, As some of you may know, the lab now has some USB keychains which might prove helpful to you in moving data around (you might put a paper on one for a conference, or maybe use it as a better floppy drive between non-networked computers). On Windows, they're basically plug-in and go (they show up as a disk when you plug them in, and you must 'eject' them via their icon to remove them safely). On Linux, once set up, they're not too complicated, and it's possible that they might show up automagically on the most recent Linux desktops (will NOT happen on facilitized RH7.1). If that doesn't happen, here are the incantations to make them work.. Initial setup, will only need to happen once: Plug in the device Run 'dmesg'. If USB is working correctly, and the mass storage drivers are loaded, you should see a notice that a new device was seen, and assigned a SCSI drive ID (If you have no scsi disks, it'll usually be sda). If this does not happen, contact me, and I'll configure your system to load the correct modules so the device is seen. Very carefully, edit /etc/fstab, adding a line like the following: /dev/sda /mnt/flash auto noauto 0 0 correct the /dev/sda part as needed. Use: To mount the device, type "mount /mnt/flash" To remove the device, first type "sync ; umount /mnt/flash", and then type "eject sda". You can then safely remove the device. We presently have 5 units, each with a 64M capacity. -- Pat Gunn Research Programmer, Auton Group, CMU From komarek at cmu.edu Tue Oct 14 19:44:24 2003 From: komarek at cmu.edu (Paul Komarek) Date: 14 Oct 2003 19:44:24 -0400 Subject: [auton-users] ivec_remove_value() Message-ID: <1066175064.11209.1.camel@laptop> Hello, On Andrew's request, I replaced ivec_remove_value() with a more sensible version. The old one was O(n^2), while the new one is O(n). I have tested the new version. Please be watch for bugs I might have missed. -Paul Komarek From agray at cs.cmu.edu Wed Oct 15 17:59:31 2003 From: agray at cs.cmu.edu (agray at cs.cmu.edu) Date: Wed, 15 Oct 2003 17:59:31 -0400 Subject: [auton-users] donut red alert Message-ID: <20031015215954.BEA6F4A7@mail.autonlab.org> there are 2 krispy kreme donuts in the lounge near the main cluster of autonlab offices... enjoy, alex From jmjoseph at andrew.cmu.edu Fri Oct 17 17:55:41 2003 From: jmjoseph at andrew.cmu.edu (Jacob Joseph) Date: Fri, 17 Oct 2003 17:55:41 -0400 Subject: [auton-users] lazy downtime Message-ID: <200310171755.41825.jmjoseph@andrew.cmu.edu> Hi. I'd like to take lazy down this weekend to upgrade it to a more modern Linux. When complete, it will run Gentoo Linux, as lina and lira do. I don't want to give a firm deadline as to when I will return it to service, but barring any major hiccups, the process should require no more than a day or two. As the status graphs indicate very little usage of any of the Alphas, and I am aware of no immediate conference deadlines, I don't expect this to be a big inconvenience. If you think it might be, drop me an email right away. Thanks, Jacob From jmjoseph at andrew.cmu.edu Tue Oct 21 02:15:19 2003 From: jmjoseph at andrew.cmu.edu (Jacob Joseph) Date: Tue, 21 Oct 2003 02:15:19 -0400 Subject: [auton-users] LAZY IS BACK Message-ID: <200310210215.19453.jmjoseph@andrew.cmu.edu> Lazy is back open for business. While I do believe it is in perfect working order after my own testing, please do let me know if you notice anything wrong or missing. If there are no problems, I will soon go ahead with Loki and Liver. As I did not preserve the ssh host key, you will likely get an error about the host being compromised. To fix this, remove the line with "lazy.autonlab.org" from your ~/.ssh/known_hosts. Then ssh again, accepting the new key. Sorry for the inconvenience. -Jacob
