Re: Gridfinity open source organization..

by Tim Keller

So far I printed out a 2x4 base plate and a couple smaller containers. I love the idea that the system is totally open and there are step files available so you can expand on it. between copious amounts of ikea skadis pegboard and my tool chest I think I can organize my tools in a way where I can adhere to the Adam Savage rule of first retrieval. Since we have a meeting this Thursday, this can be yet something else to talk about. Tim.

Re: Hierarchical note taking, Joplin, Trilium, browser extensions, etc..

by Tim Keller

Sadly no. I've looked at DokuWiki a couple of times. The problem is this. I'm lazy. The lowest barrier to entry is simply a directory called "Notes" with a bunch of text files. Being text and using a unix-like system, I've got tools like grep to find stuff. I figure the next lowest thing is some program that lets me take notes that I can then organize into some index and search against it as well. Beyond that now it becomes hosted somewhere, etc. Tim.

After moving ethernet cables around to do jit.sw/WlugMA last Thursday, I discovered I had broken another one of those stupid little plastic latch pins on the end plug. I bought a bag of a dozen at Stark electronics about the time of Doug's talk two decades ago. I am down to just three of them. Stark is long gone; where can I get more? I thought of Google, but I could not remember what the plugs were called. After paging quickly through a few slides, there was the answer! They are called RJ-45 plugs and you can buy them through Amazon. They come in bags of 100, which is excessive, but not too expensive; ($10-15). I suppose I will get a bag. That's more than a liftime supply. In a couple more decades you will be able to pick up about 90 of them _real_ cheap at the estate sale, or free from the dumpster. -- Keith

Yet Another Perl Conference final details

by Gerard Lim

Hi everyone... This email could be of interest to people interested in the Perl programming language. I know that in Toronto there is a good-sized overlap between Linux people and Perl people (we occasionally hold "joint sessions" of our user group meetings) so we hoped to share this information with Linux folks more widely. There have been some recent developments on the YAPC::NA front, and it has been suggested to us that a reminder might be helpful to some people, so here's a quick summary of the event. Summary ------- YAPC::NA 2005 (Yet Another Perl Conference, North America) in Toronto, Canada, Monday - Wednesday 27 - 29 June, 2005 Home page: http://yapc.org/America/ Conference Location: http://89chestnut.com/ A facility of the University of Toronto Accommodations -------------- Normally registration information would come first, but accommodations are the bottleneck -- our main group reservation (at the conference hotel) expires at the end of the week, and as the conference approaches it will be extremely difficult to find a hotel anywhere in the city. Info on how to book at: http://yapc.org/America/accommodations-2005.shtml Registration ------------ Register now! :-) We are on track to break attendance records at YAPC::NA this year, and we could even sell out before the conference starts. The price for the full 3 days is USD$85. We keep it insanely low through many generous sponsorships and the all-volunteer organizational and speaking crews. Registration info: http://yapc.org/America/register-2005.shtml Direct registration link: http://donate.perlfoundation.org/index.pl?node=registrant%20info&conference… Conference Speaking Schedule ---------------------------- We've got an excellent selection of talks and speakers for Perl programmers of all levels, beginner through expert. We are fortunate enough to have presentations coming from some of the most recognizable names in Perl programming today, including Larry Wall, Chip Salzenberg, Dan Sugalski, Autrijus Tang and brian d foy. Summary -- http://yapc.org/America/schedule-2005/summary.html Day 1 -- http://yapc.org/America/schedule-2005/day1.html Day 2 -- http://yapc.org/America/schedule-2005/day2.html Day 3 -- http://yapc.org/America/schedule-2005/day3.html Lightning Talks --------------- These short (5 minutes each) talks, presented by the conference attendees, are a YAPC tradition.

RE: [Wlug] VNC performance

by Jeremy

FYI: Regedt32 is a slightly uglier RegEdit but includes the ability to change the permissions of certain keys (i.e. driver enum keys etc). Even when logged in administrator (which is probably why you cant change the registry - are you logged in as administrator or similar rights?) certain keys do not have write/delete access. Using regedt32 allows you to change the permission (assume admin rights) of such keys and therefore modify them. I only use regedt32 as a last resort when modify the Windows Registry, otherwise use regedit. --- "Evans, Robert" <Robert.Evans(a)stratus.com> wrote: > Try using a registry editor on Windows: > (Typically in these places on Windows 2000) > C:WINNT egedit.exe > C:WINNTsystem32 egedt32.exe > > Robert N.

Hi all Yury I Vashugin wrote: > first, we need people to produce the show. it's a commitment of half an > hour ones? a month.(could be ones in two months) is there anyone who > would like to join the venture? I have been lurking and on the horns of a dilema. The above comments got me off the fence. (On re-reading, that is an atrocious mixed metaphor --- natural talent!) :-) Then general idea of proseletizing strikes me as reasonable. However, I think it is a good idea to do as good a job as possible. Although I admit to little direct experience with such exercises, my impression is that they should not be lightly undertaken. In particular, I gather it takes about ten hours preparation for one hour of finished product (and that ratio is probabley optimistic). You have to identify your audience, identify, rank and organize what topics should be covered, decide on how best to utilize the time, write some sort of at least a detailed outline, if not a full script, try dry run(s). etc. So far, all I see is the idea that a group of well-meaning people are supposed to show up and "wing it". Sounds like a disaster waiting to happen. The discussion at the end of the last WLUG meeting demonstrated little more that that there were about as many views as to how to proceed as there were people in the discussion. Lots of chiefs, no indians. Now I readily confess that I am very good at spotting the negative side of just about anything. :-) (On a plane ride from Florida to Philadelphia, I once convinved a pharmacological colleague that an idea he was exploring made no sense at all. Years later, when Julie Axelrod got the Nobel prize for that general concept, I had one of those "oh shit" moments. Fortunately for me, the guy from Philadelphia, it turned out, had dropped the issue, but not on the basis of my comments.) The other horn of my dilema, is that I would like to help, but don't want to appear and just be a wet blanket. Since the "event" is right here is Shrewsbury, I'll probably show up (since I can at least function as a "gofer", pull out power cords and the like) but try to maintain a low profile. doug

Re: [Wlug] Test needed on declared-ill Modem. Who has a lab?

by Eric Martin

Make sure that you update the MAC address with charter, and that they actually update it. I've had a few problems where they haven't even though they said they did. Also, a lot of modems have diagnostic suites built in. An easy enough way to get at it is to turn it off, and unscrew the coax line. Now boot it up, and it won't get an IP from charter, but it should give your router an ip like 193.168.100.100, and the gateway should he something like 192.168.100.1 (check for specifics) but that gateway is your modem. Punch that IP into a browser and see what comes up, usually the password is something stupid, and a Google search will yield it if its not admin. Keep in mind you pulled the cable, so it will show that. This will also work when you have no internet, and it usually shortens phone calls with Charter. sent from my mobile Eric On Sep 26, 2012 10:42 AM, "Richard Klein" <rich(a)richardklein.org> wrote: > Liz, > I live in Clinton these days, where Verizon DSL and Comcast are the > only options.

GNU ddrescue is the more advanced of the two and I would recommend it over dd_rescue--it may be able to recover more data (unless you use the cumbersome dd_rhelp helper shell script with dd_rescue). Check this out: http://www.toad.com/gnu/sysadmin/index.html#ddrescue > BTW, this is what I was missing. there was no warning that my disk was > bad! Like I said, I have backups but the last one failed so I want > something tighter I run smartd (from smartmontools) and mdmonitor (mdmon) as daemons to monitor for SMART errors and array issues. On Fedora/Red Hat like systems this is as simple as: chkconfig mdmonitor on chkconfig smartd on service mdmonitor start chkconfig smartd start (and making sure that root mail goes somewhere useful) mdmon will monitor the arrays that are specified in /etc/mdadm.conf (which incidentally is written automatically by the Fedora installer) and let you know if any component device of an array has trouble or drops out for any reason. smartd will monitor devices listed in /etc/smartd.conf (or with DEVICESCAN it will scan and monitor all available ATA/SCSI devices on the system) and let you know if you start getting uncorrectable errors, reallocated sectors, etc. which can be a nice early-warning system. I usually replace disks as soon as a single sector is reallocated or "pending". But even with these, you still should "scrub" the array--try to read every sector on all devices that make up the array--to find errors that might otherwise be missed. I believe that is what the checkarray script that John posted about does. checkarray appears to be a Debian-specific script. My Fedora system has a similar one called raid-check: /etc/cron.weekly/99-raid-check /etc/sysconfig/raid-check #!/bin/bash # # Configuration file for /etc/cron.weekly/raid-check # # options: # ENABLED - must be yes in order for the raid check to proceed # CHECK - can be either check or repair depending on the type of # operation the user desires. A check operation will scan # the drives looking for bad sectors and automatically # repairing only bad sectors. If it finds good sectors that # contain bad data (meaning that the data in a sector does # not agree with what the data from another disk indicates # the data should be, for example the parity block + the other # data blocks would cause us to think that this data block # is incorrect), then it does nothing but increments the # counter in the file /sys/block/$dev/md/mismatch_count. # This allows the sysadmin to inspect the data in the sector # and the data that would be produced by rebuilding the # sector from redundant information and pick the correct # data to keep. The repair option does the same thing, but # when it encounters a mismatch in the data, it automatically # updates the data to be consistent. However, since we really # don't know whether it's the parity or the data block that's # correct (or which data block in the case of raid1), it's # luck of the draw whether or not the user gets the right # data instead of the bad data. This option is the default # option for devices not listed in either CHECK_DEVS or # REPAIR_DEVS. # CHECK_DEVS - a space delimited list of devs that the user specifically # wants to run a check operation on. # REPAIR_DEVS - a space delimited list of devs that the user # specifically wants to run a repair on. # SKIP_DEVS - a space delimited list of devs that should be skipped # # Note: the raid-check script intentionaly runs last in the cron.weekly # sequence. This is so we can wait for all the resync operations to complete # and then check the mismatch_count on each array without unduly delaying # other weekly cron jobs. If any arrays have a non-0 mismatch_count after # the check completes, we echo a warning to stdout which will then me emailed # to the admin as long as mails from cron jobs have not been redirected to # /dev/null. We do not wait for repair operations to complete as the # md stack will correct any mismatch_cnts automatically. # # Note2: you can not use symbolic names for the raid devices, such as you # /dev/md/root. The names used in this file must match the names seen in # /proc/mdstat and in /sys/block. ENABLED=yes CHECK=check # To check devs /dev/md0 and /dev/md3, use "md0 md3" CHECK_DEVS="" REPAIR_DEVS="" SKIP_DEVS="" Finally, if you do come across bad sectors on a device, they will only usually be reallocated to a spare sector on the media when the sector is written to rather than just read from. As a last ditch "I really want to continue using this bad disk, please just reallocate the bad sectors and I'll deal with the data that is already lost" you can try to force a reallocation with hdparm --repair-sector: --repair-sector This is an alias for the --write-sector flag. VERY DANGEROUS. --write-sector Writes zeros to the specified sector number. VERY DANGEROUS. The sector number must be given (base10) after this flag. hdparm will issue a low-level write (completely bypassing the usual block layer read/write mechanisms) to the specified sec- tor. This can be used to force a drive to repair a bad sector (media error). But I would really think about replacing any disks that have developed such bad sectors, as it is only a matter of time before you run out of spare sectors to reallocate to.
