Re: An experiment about file timestamp
Rodolfo Medina wrote: Chris Jackson c.jack...@shadowcat.co.uk writes: File timestamps are (or at least should be) stored in UTC. It's the display of them that's affected. But I did the following experiment: on a computer with system time set to UTC, I created a file at 14:43 UTC. Then I copied it via rsync and ethernet cross cable to another PC with system time set to GMT, one hour late respect to UTC. I expected that, on the 2nd PC, the timestamp was displayed in the local time, i.e. 15:43; instead, it appears as 14:43 as well. (For the copy I used the -t option.) So, according with this experiment it is not true that the displayed time is in local format. I think this may cause serious errors: in fact, when someone read the timestamp on the 2nd PC, he would believe that the file were created at 14:43 of the GMT time, which is wrong: in fact, it was created at 15:43 GMT = 14:43 UTC. What do you all think? Rodolfo GMT, as far as a computer is concerned, is the same as UTC. The difference is that GMT is a solar time and may be up to a second different, however since computers don't make solar observations, they're the same in implementation, and many people use them loosely to mean the same thing. http://en.wikipedia.org/wiki/Coordinated_Universal_Time Paragraph 4 of the introduction, plus discussion under History.

It's the display of them that's affected. Setting the TZ variable may help: export TZ=UTC Timestamps stored _in_ files (for example log files) are taken from system time, that stored in /etc/localtime. You might want to set that to UTC and, where required, alter the displayed time using the TZ variable, rather than running system time on something with DST, since it can cause problems with timestamps within log files etc. being duplicated around the time of the change. cp /usr/share/zoneinfo/UTC /etc/localtime Or, you may wish to use a nearer-local non-DST timestamp: cp /usr/share/zoneinfo/Etc/GMT-1 /etc/localtime Personally I find using UTC/GMT on all our systems, wherever based, as system time the simplest, and managing the displayed time using TZ as applicable.

One trick that comes to my mind is to use a data rate threshold tool to
limit the data rate input is fed to the application.
$ threshold --rate 20KB/s data_source | my_greedy_application
Is there such a tool in Debian?
I don't know about a tool, but assuming it's not important that the rate
is precise as long as it's somewhere about right, a simple perl script
will do it. You can probably do similar things with python etc.
The following takes a rate in bytes a second and optionally a block size
in bytes, and writes a block of data at the appropriate interval (no
--rate - so if you save it as threshold invoke it as threshold 20480
- for 20kB/s). Default block size is 1k. Note that I only just wrote
it, so YMMV and take it as an example for experimentation ;) Should be
fairly obvious how it works; note it'll do silly things if you give it
silly arguments, in particular very large block sizes.

Re: Bash question: get output as a variable?
Dotan Cohen wrote: I'm scripting a backup solution, the line that does the business looks like this: tar -zcvf - * --exclude-from $EXCLUDES | openssl des3 -salt -k $1 | dd of=$(hostname)-$(date +%Y%m%d).tbz Because of the v flag tar writes to stdout the name of each file copied. How can I get that output redirected to a variable, to use later in the script? Thanks! Use $() like you do with the date command. You have to redirect stderr back to stdout, which means running it in a subshell: FILES=$( ( tar -zcvf - * --exclude-from $EXCLUDES | openssl des3 -salt -k $1 | dd of=$(hostname)-$(date +%Y%m%d).tbz ) 21 ) It may cause unexpected results if there're spaces in the filenames though. -- Chris Jackson Shadowcat Systems Ltd. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Thanks, Boyd, that was actually ver informative. As there is no room for a second tower, I will see about modding the existing tower for two motherboards. There actually is room, only the CPU cooling tubes might be problematic. Oh, and I'm going to have to see if a single 500W power supply with another pigtail soldered will power both! That should probably be the weak point in the system! I actually think this just might be possible, although I'm by no means sure. I've got as far as running an X session on a separate video card in the past, for display purposes only (that is, we ran for example `DISPLAY=0:1 mplayer' to use the alternate display). I experimented briefly with trying to get an actual xdm session on there, and while I could get it to start, the problem was in picking up which device which keyboard/mouse was attached to. I'm curious about whether this is possible with udev, since that was in the days before it - I think it may - possibly - be, and might have some time to experiment this weekend if you're still interested. -- Chris Jackson Shadowat Systems Ltd. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

I seem to remember it asked whether i wanted support for every known piece of hardware out there, and I don't know when to say Y or N.. I think you may have done make config rather than make menuconfig. Menuconfig - at least should - provide a menu-based interface you can select packages from. It can still take a while, but much faster than being asked for each one which is... somewhat unwieldy these days. Similarly, make xconfig provides an X-windows interface; I've never used this. One way of getting a list of modules you might need is to start with a stock kernel based on using modules, perhaps from a live CD. Start anything you want up, then do lsmod which will get you a list of all the modules it's loaded. Mapping between the module name and the exact option needed is not always as easy as it might be, but we'll call that learning experience ;) Apart from that, you have to anticipate: for example if you think you might need USB printing, but don't have one right now, perhaps include it. -- Chris Jackson Shadowcat Systems Ltd. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
