What do ASCII codes 128-159 stand for?
"man ascii" defines the ASCII codes from 0-127, and the various ISO-8859-x tables define the ASCII codes from 160-255 (depending on your character set), but are there standard representations for the ASCII codes between 128 and 159 inclusive? -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology.

Using rsync for versioned backups without --backup
I want to use rsync to backup a large file (say 1G) that changes a little each day (say 1M), but I also want the ability to re-create older versions of this file. I could use --backup, but that would create a 1G file each day, even though I only "really" need the 1M that's changed. How do I tell rsync: "while updating, also store the changes you'd need to convert today's backup into yesterday's backup"? I realize I could use diff or something, but since rsync has to calculate minimal changes anyway, it'd be nice to store them. I thought the --itemize-changes option might do this, but no. -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology.

Because of that you have to set the clock on bootup by some means such as ntpd or ntpdate. If a shell is currently open when the time is set, you get some weird numbers too. So my question to you is if this is a board that has the same hardware problems? Is it a bad RTC that prevents accurate timekeeping? need to tune kern.clockrate? tune kern.timecounter.choice?

Watchdog timer
What's the proper way to configure the watchdog timer service so that a system will automatically reboot after five minutes of non-responsiveness? I tried setting watchdog to run with the args "-s 10 -t 300", but I've seen systems reboot after only a few seconds of inactivity (such as being hung on an I/O wait) instead of the full five minutes specified by the -t option.

Secure unsalted or fixed salt symmetric encryption?
Are there any secure openssl symmetric encryption routines that *don't* use a salt? Is it secure to use a random-but-fixed salt (openssl enc -S salt)? "man enc" says "This option [-salt] should ALWAYS be used [...]" Reason I ask: I was using this command to backup files using compression/encryption: bzip2 -k -c original | openssl enc -bf -pass file:passfile > encfile and was surprised that doing this to identical files yielded different results. I then realized "openssl enc" randomly(?) chooses a salt if you don't supply one. I want my backups encrypted, but I also want identical files to encrypt identically.

The CRON_TZ variable can be set to an alternate time zone in order to affect when the job is run. Note that this only affects the scheduling of the job, not the time zone that the job perceives when it is run. If CRON_TZ is defined but empty (CRON_TZ=""), jobs are scheduled with respect to the local time zone." Problem is, CRON_TZ just doesn't work as written above. If you insert CRON_TZ=America/New_York and then write the * * * * * (schedule) to reflect NY time (say), but your server time is Chicago, cron ignores the CRON_TZ definition. Here's a CRONTAB extract which provides a good example of the odd behaviour: # - sample crontab # change tz and cron_tz to America/NY TZ=America/New_York CRON_TZ=America/New_York # check that timezone change 'stuck' (commented out except for testing) * * * * * printf "CRON_TZ is now "$CRON_TZ".

Now doing Australia Sun May 24 21:02:01 EDT 2009 CRON_TZ is now America/New_York. Now doing US 'date' is right, and $CRON_TZ changes as expected, but has no effect in cron. One other thing strikes me as odd: the output file is in reverse order to the crontab. If changes to CRON_TZ actually worked as written, then one would need to verify that the changes propagated 'downstream' from the variable declaration. It's not that output is being written to the top of the outfile though - output in subsequent minutes is APPENDED to the outfile. And now for the big "DUH, I'm an idiot" moment - apparently FreeBSD, Fedora and Ubuntu don't have CRON_TZ support built in.

Thew issue seems to be that cron pays no attention to TZ declarations that happen AFTER it wakes up - cron does not parse the job times using the new TZ. The thing I am struggling with is that 'date' picks up the changes imposed by 'TZ=', but then 'cron' parses the next line as if the job times are interpreted using the server's default TZ. I've tried using 'CRON_TZ=' as well as, and instead of, 'TZ=' - to no avail. What I thought ought to happen is this: * 'cron' wakes up; * 'cron' works through the crontab line by line; * at line 1 cron changes the TZ to America/NY; * at line 2 cron reads the job time in the context of having just been told that it's operating in the NY timezone (thus 45 13 * * * is 1:45 pm NY time); . . . * at line 15 cron is told to change the TZ to Australia/Sydney; * from line 14 onwards, 45 13 * * * is 1:45 pm SYDNEY time. . . . and so on. It seems that cron behaves as if it forgets $TZ at each newline within a given cron instance. The silly thing is, with all the time I've wasted pursuing this wild goose I could have built the required four crontabs, and written the script to swap them in and out on the appropriate dates.

The load average in FreeBSD is an average of the number of processes ready to run or waiting for short-term events such as disk I/O to complete, as sampled once per second over the previous one- minute interval of system operation. so this glossary should be fixed because it's nonsense. first - says that it's measure of CPU load then - "or waiting for short-term events such as disk I/O" - which is NOT measure of CPU load. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

In order to save some time, it could be possible to pkg_add -r the dependencies first, then run the "make install clean" command in win4bsd's directory.

I would tend to buy one myself in the future, especially for LAN and WLAN diagnostics (at the customer's site). I like the concept of the SSD in opposite to a "moving parts" classical hard disk. Size and battery life are okay (for what they are intended for), and I think older models of the EeePC will get a bit cheaper over the time.

Look below: load over 7 and no processes take much CPU. load average is NOT sum of CPU loads. for example program reading constantly from HDD and using no CPU will add 1 to load average. other things like net I/O etc. are calculated too. i can't explain you exactly how because i don't know precisely. but load average is total load not just CPU load Yuri 7.2-PRERELEASE, 32-bit on i7-920. last pid: 93192; load averages: 7.68, 6.27, 4.61 up 2+03:11:29 20:25:24 204 processes: 9 running, 193 sleeping, 1 stopped, 1 zombie CPU: 5.3% user, 0.0% nice, 0.0% system, 0.0% interrupt, 94.7% idle Mem: 867M Active, 1684M Inact, 279M Wired, 65M Cache, 112M Buf, 92M Free Swap: 16G Total, 142M Used, 16G Free PID USERNAMETHR PRI NICE SIZERES STATE C TIME WCPU COMMAND 60032 yuri 1 460 285M 183M select 0 41:15 0.59% Xorg 60400 yuri 1 40 12576K 9144K kqread 4 29:44 0.00% wineserver 92982 yuri 1 440 53012K 16800K CPU3 3 18:50 0.00% kdeinit4 92986 yuri 1 440 53012K 16800K CPU7 7 18:48 0.00% kdeinit4 92988 yuri 1 1070 53012K 16840K CPU6 6 17:22 0.00% kdeinit4 60104 yuri 1 440 132M 45860K select 0 16:58 0.00% kwin 92984 yuri 1 1170 53012K 16800K RUN5 14:56 0.00% kdeinit4 60096 yuri 1 440 89732K 30040K select 4 10:10 0.00% kded4 93141 yuri 1 530 53012K 16800K CPU5 5 3:52 0.00% kdeinit4 93139 yuri 1 440 53012K 16800K CPU1 1 3:30 0.00% kdeinit4 60174 yuri 1 440 3168K 1400K select 0 1:28 0.00% ksysguardd 450 root 1 40 3128K 800K select 4 0:44 0.00% dhclient 1131 messagebus1 40 3344K 1384K select 4 0:40 0.00% dbus-daemon ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org" ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

The load average is the number of processes in the queue for a CPU time slice averaged over 5, 10 or 15 minutes. For multi-core systems the LA is scaled by the number of cores so a LA of 1.0 means all cores have active processes pretty much continually. I thought, if it was a dual-core for example, a load average of 1.00 would indicate 50% CPU utilization overall (1 process using only 1 core)[1]. 2.00 on a dual-core would be 100%, 3.00 on a dual-core would be 100% utilization, and always 1 process in the wait queue, and so on. It seems both ways have been used in different OSes, which is confusing. A quick test of a single threaded process that will spin one CPU on a multi-core FreeBSD box shows the value is /not/ scaled by the number of cores. Which means that the LA the OP was talking about is actually a lot less alarming than it originally appears. It's clear from the top output that his machine has at least 8 cores, so a LA of 7 is really not very heavily loaded. Now, you might think that an active process will take the CPU utilisation to 100%, but that is not necessarily so. Some numerical applications can do that, but purely CPU bound processes are relatively uncommon in everyday usage. In actuality what happens is that the processor will need to retrieve data from somewhere to operate on. There's a hierarchy of data stores of various speeds (latency, rather than bandwidth): L1 Cache > L2 Cache > L3 Cache > Main RAM > Disk > Network Does this affect the load average though? My understanding was that if the CPU cannot immediately process data, the data gets put into the wait queue until L2 Cache (then RAM, etc, etc) returns the data to be processed. Yes it does: when a process is on the CPU and blocked waiting for IO it does not necessarily yield the CPU to another process. It depends on timescales -- obviously if the CPU will have to wait milliseconds for data it makes no sense to block other processes. Waiting a few microseconds is a different matter though: it might take that long to load up L2/L3 cache with that processes' working data, so yielding the CPU for that sort of delay would mean the process never got run, which is counter productive... It helps if the working set is already in the L3 cache -- so having the correct amount[*] of cache RAM available is an important design criterion. It's something that Intel was shown to have got wrong with some of the Pentium series chips when a low powered Pentium M designed for mobile use smoked a much higher clock speed Pentium chip designed for all-out server use simply because it had about 4x as much cache.

This is not an uncommon occurrence really. The load average is the number of processes in the queue for a CPU time slice averaged over 5, 10 or 15 minutes.

Now, you might think that an active process will take the CPU utilisation to 100%, but that is not necessarily so. Some numerical applications can do that, but purely CPU bound processes are relatively uncommon in everyday usage. In actuality what happens is that the processor will need to retrieve data from somewhere to operate on. There's a hierarchy of data stores of various speeds (latency, rather than bandwidth): L1 Cache > L2 Cache > L3 Cache > Main RAM > Disk > Network Where the L1 Cache is accessible in a few clock ticks (nanoseconds), Main RAM can take microseconds to access, disk can take milliseconds to access, and Network can take 10 -- 1000s of milliseconds. Or in other words, about 9 orders of magnitude difference. So when the data you need to process is too big to fit in the fastest caches, or when it comes from a particularly slow location or when you have a lot of active processes causing context switches, then the CPU core will be making frequent IO requests and spending time waiting for them to be fulfilled. Now, for sources like disks and network where the retrieval is much slower than the typical timescale of events on the CPU the process will yield the CPU to something else and only get a new timeslice once the IO request has been fulfilled. For an access to main RAM however that form of yielding is less likely. Consequently the CPU can end up waiting for 100s of clock cycles until it gets some bytes to process. In the mean time, other processes are also sitting in the queue wanting CPU time slices -- hence the high LA with low CPU utilization. Scheduling CPU timeslices to make maximum use of available resources is the difference between a really performant OS and a disaster. A good scheduler is the critical central piece of code around which the rest of an OS can be constructed. Combine that with the complexity of having multiple cores, and that threads of execution sometimes have to be moved to different cores, and on other occasions sometimes need to stick to the same core in order to make best use of resources and you will start to appreciate quite how hard it is to write a good scheduler. Unsurprisingly, the design of such things is a matter of fairly impassioned debate amongst the rarified circle of people capable of writing them. That sort of argument was the genesis of the FreeBSD / DragonflyBSD fork a few years back. You can rest assured though that FreeBSD certainly does have one of the very best schedulers currently available and it is specifically targeted at getting the best out of the sort of multicore CPUs available nowadays.
