Winnipeg Harvest donations from December meeting - thank you!

Thanks to the generosity of our members, we were able to donate three large boxes’ worth of non-perishable food items to Winnipeg Harvest in December 2010. The text of the thank-you letter we just received (see attached) is as follows: January 5, 2011 Manitoba UNIX User Group Attn: Adam Thompson Dear Friends of Harvest, We here at Winnipeg Harvest want to thank the Manitoba UNIX User Group for your support of helping those less fortunate in our community. Over the last few months 743 pounds of food was donated to the food bank. Your donations will go into hampers that will help Winnipeg Harvest feed more than 58,000 people each month, half of those being children. On behalf of the entire team at Winnipeg Harvest, thank you for helping us fight hunger and feed hope in Manitoba. We look forward to working with you again in the future. If I can ever be of assistance, please don’t hesitate to contact me by phone at 982-3670 or by email at tori(a)winnipegharvest.org. Yours truly, Tori Webber Development Associate Winnipeg Harvest Inc. So, thanks again. See you all in another six (6) days, at our next meeting on January 11th, 2011. -Adam Thompson athompso(a)muug.mb.ca

Computational usage
by Robert Keizer 26 Aug '11

26 Aug '11

Well I thought I'd share this with everyone, interesting screenshot at the least. I found a usage for all the compute power my new laptop has, including the gpu. Note the load in the background terminal. Also: turns out some laptop bios's are smart enough to clock down and not let you clock back up within a given timeframe if they hit 99C. GPU was most likely hotter, but its rated for I think 150C. Rob

Why not install GNU tar from sunfreeware? Actually, come to think of it, GNU tar should be part of the semi-supported freeware packages on the Solaris DVD... -Adam Kevin McGregor <kevin.a.mcgregor(a)gmail.com> wrote: >It turns out that /usr/sbin/tar on my Solaris 10 system is not statically >linked (there is no /usr/sbin/static, and I checked ldd tar).

Mounting UFS
by Kevin McGregor 25 Aug '11

25 Aug '11

I have a TAR file (well, many) created with Solaris 10. I can restore it under same, but it seems the Solaris version of tar doesn't give you the option of stripping the leading "/" when restoring, which is a slight problem for my situation. Did I miss something, and it can restore to a relative path after all? Does anyone have any other suggestions, such as other utilities to use or even OSs with a more flexible tar that can mount a UFS slice? Kevin

ldapsearch(1) word wrap
by Adam Thompson 13 Aug '11

13 Aug '11

If you're using LDAP, you've probably run into an annoying feature of the LDAP standard: all LDIF-compliant output shall be wrapped at 80 characters or less. The LDAP standards explicitly specify how wrapping shall take place, but the column width varies from one program to another. Some implementations of ldapsearch(1) accept the "-T" option to turn off wrapping, or "-r 0" to specify wrapping at column #infinity. OpenLDAP's version, however, does not accept any such option. There's an easily-discoverable (i.e. googleable) way to remove the peculiar line wrapping, by running ldapsearch [all the various options] | perl -p00e 's/\r?\n //g' which works equally well under Windows or under UNIX. Since I hate typing in a command like that over and over, I thought to use a shell alias to make my life easier. Shell aliases, as I discovered, do not permit parameter substitution. So, when I tried this: alias lds='ldapsearch "$@" | perl -p00e "s/\r?\n //g"' it didn't work. The solution is to use a shell function, and this is now what's in my .bashrc (I removed the \r? which took care of DOS EOLs, since I'm not running DOS here): lds() { ldapsearch "$@" | perl -p0e 's/\n //g' } In perl 5.8.8, at least (which ships with RHEL/CentOS 5.6), the default option to '-0' is \000, so specifying -00 is redundant. And possibly incomplete anyway, since it's supposed to be octal (3 digits). I hated the thought of exec'ing perl just to do this, but it turns out there's no way to do it with sh, sed, awk, or tr because we're manipulating newline characters. Oh, well, perl's been in production use since ~1992, it should be stable by now. Note: yes, it is probably *possible* to do it in shell or awk by specifying a replacement IFS, something like: lds() { ldapsearch "$@" | read -d '\0' X; echo ${X/\n /g}; } but it didn't work for me after about 15 minutes of fiddling and testing. On the other hand, even bash doesn't like single variables exceeding about 32KB, and some LDIF output can be huge. At least with perl you can process LDIF output up to the size of your remaining VM (eventually). There are specialized binary stream editors (like bbe-) that might be more efficient but those aren't typically already installed. Some people post junk like this to their blog; I'm old-school, I figure a mailing list that Google indexes is good enough for me :-D. -Adam Thompson athompso(a)athompso.net

There’s a oddly-strong correlation between UNIX geeks and camera geeks, so I figured I’d post this anyway: http://photojojo.com/store/awesomeness/lens-shot-glass/ -Adam Thompson <mailto:athompso@athompso.net> athompso(a)athompso.net (204) 291-7950 - direct (204) 489-6515 - fax

Solaris DVD copy
by Kevin McGregor 08 Aug '11

08 Aug '11

At work we have a Sun Fire V490 with Solaris 10 Update 3 installed. We'd like to do some trial runs of upgrades from U3 to U4 and U9. We have a DVD copy of U9, but we're having trouble getting a copy of U3 or U4 to play with, even from Oracle. Does anyone have a copy of Solaris 10 U3 and U4 (SPARC, of course) I can borrow? It would make my job a lot easier. Thanks! Kevin
