While I presume that the start up sequence normally handles this by clearing /var/run before lighting off the init scripts for the level, I have a need to have my pid file in an unusual place (needs to be written and deleted by a non-root process). I'd like start at boot to be automatic, and if shutdown was clean, it will be. But if the system crashes (or someone hits the reset button, etc.) there will be a stale pid file come boot time. I'd like to automatically delete any stale pid file at boot time, but start later should fail claiming that there's an existing process. So, can I count on parent pid, or maybe process group id, to identify the at boot time case? Or would that be unwise?

I'm looking for a replacement, but I want a particular..."mindset" is probably a better word than "feature". On a recent long-distance car trip, I found the GPS making opaque decisions. For instance, it has a route. I take an unplanned exit for gas and when I get back on, and the GPS has "recalculating"'d several times, the route is different. Why? I'm exactly where I was before and the destination is the same. No clue and no way to find out. Similarly, I often find that "fastest" and "shortest" are not the only optimization strategies I could wish for. How about "any route using/not using road X" or "no tolls, except for this one because it saves 4 hours"? Or "no 'highways' but also don't take me down all these back country, one-lane roads". Basically, I find that when I use the GPS, it's the brains and I'm just the car operator. I want to be the brains and the operator and have the GPS be navigator. I decide a route (or the backbone of one) and it keeps me on it. Does this exist? I know "waypoints" is a thing, but I'm not talking about visiting landmarks. I'm talking about entering in (most of) my route and having the GPS handle the details. </pre> David Rysdam 2013-05-18T01:18:45 http://comments.gmane.org/gmane.org.user-groups.linux.gnhlug/22539 <pre>Join us Tuesday May 21st for ManchLUG!

Their words are quoted (since I don't know how to highlight in ascii): "Microsoft donates Windows licenses to organizations such as ours, millions each year." Yes, I'm sure they do. The better to get their malware into the hands of the unaware. "When you are poor and want to get a job employers want people that know Word, Excel, PowerPoint, Outlook, Visio, Project, SharePoint, Dynamics and hundreds of other standard business programs offered by Microsoft." Translating skills from one Office suite to another, such as OpenOffice to Microsoft Office, is not different from translating between different versions of Microsoft office. However, on the rest of these applications, I agree. Somehow, I doubt that they're getting free licenses for all of them. The same objection to the expensive upgrade treadmill exists for these applications as well. "We tried to offer Linux systems with open office for $25 a system when we started, never had one person ever look at one - we can't even give them away - I tried to." No, they tried to sell them, not give them away. Even allowing that they dropped the $25 pricetag, it's a fact that people think that Windows is Free. The comparison in their minds is not the $200 Windows license vs. $0 for Linux/LibreOffice, it's between $0 with the Microsoft label and $0 without it. The choice is obvious. I have written about this before: http://anarchic-order.blogspot.com/2011/03/windows-is-not-free.html And it is the "poor" who are least able to afford not getting hacked/cracked upgrades "from a friend" when their "free" Windows runs out. "They want Windows or Apple and Apple has no interest in poor people. If you have kids they want to play games - not Linux games, good games that their friends are playing online." Three gross assumptions here: 1) Microsoft cares about people who cannot afford their software 2) Linux games are not good 3) Online games don't run on Linux 2 and 3 are sadly somewhat true, yet rapidly declining. I have to wonder what these "poor" people are doing paying for first-run games and online game time. Maybe they're getting hacked/cracked versions of them? 1, however, is absurd. Microsoft Corporation wants people to buy their product. By giving this one away just like the drug dealer, they perpetuate the illusion that there is nothing else. "I think there are lots of zealots running around that think they have the only solution for mankind when in fact there are many." Zealots also push Microsoft crapware. "You seem to have twisted 'the value of genuine' - all that means is LEGAL not cracked or virus ridden." This copy is all nice and legal, sure. What about the upgrade that the "poor" will soon have to buy? Will that also be all legal and not cracked or virus ridden? No. Only the first one is free. Giving people Windows and Microsoft crapware is not doing them any favors.

This next generation, credit-card-sized, open-everything microcomputer sells for $45 and offers broad, capable support for Linux Distributions and Android. This is a defining moment for Open Source Computing. The May 15th meeting will take a hands-on, hacker-friendly look at the new BeagleBone Black. We'll step through board-level operations from boot-up to shutdown, from launching Linux to blinking LEDs. Chip by chip, Texas Instruments is ushering in a new generation for Open Source Computing. Is BeagleBone Black a capable desktop or energy efficient server? Will you run ngstrm, Ubuntu, Android or something else? Will it be used in educational, personal, or commercial settings? We'll tour through software and hardware ideas for Infotainment, Thing-ware, and Maker applications. Join Brian and Kurt (some call them the caped crusaders of the embedded world) as they look back on industry developments since BLU's PandaBoard meeting of 2010 and lock in on the promising potential for the brand new BeagleBone Black.

The installer seems to timeout because the host (or my network) is not responding. What is puzzling, is that I can wget the file from the repository. The download seems to take &gt; 3 minutes to start, (no wget activity) but then the connection is good for a while, stalls, but eventually picks up and completes. When the connection is active, I seem to have reasonable BW, otherwise I have 8B/sec or 0B/sec download. It is probably our network $WORK, but I have yet to have anyone be able to help me. Since I have the file in question, where can I stuff this file, so that the installer sees it, and doesn't have to go to the slow repo to get it again. I think the dist-upgrade saves stuff in /var/log/dist-upgrade In main.log the last entries are: 2013-05-03 10:31:40,603 ERROR IOError in cache.commit(): 'Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/t/texlive-extra/texlive-fonts-extra_2009-10ubuntu1_all.debConnection failed '.

I've long been partial to Debian, although I have used a number of different flavors in the past (started out around RH 5.0, also ran CentOS on a couple DEC Alpha's, etc.) I'll give some specifics on the netbook in question. I am mainly looking for feedback/advice/caveats from anyone who may have already dabbled with this sort of project. I recall having some compatibility issues with dual-booting on an inherited laptop some years back due to a few proprietary components (I had to use a 3rd party adapter or two, due to "windows only" issues with the built-ins). I'm not set in stone, so if another flavor has a better fit for netbooks, I'd certainly consider it.

This is going to get into religious territory. I am of the opinion that while SpinRite is not a total scam, it's highly overrated, mostly obsolete, and all of it's useful functionality is now available in free programs elsewhere. SpinRite *may* have had some relevance back in the days of MFM, when hard drives were powered by steam and people still thought MS-DOS was a good idea, but it's not worth paying for these days. And some of the claims made by the author are bunk and always have been. SpinRite will read every block on the disk, to make sure they still can be read. This is useful. But even CHKDSK/SCANDISK will do that, and have since DOS 6, circa 1993. SpinRite will read-and-rewrite blocks. There are scenarios where this may be a plausible benefit, such as allowing the drive's built-in relocation mechanism to relocate a marginal sector. But "badblocks -n" will do the same thing, for free. SpinRite will read blocks over and over again. If a read fails, it will keep trying until it succeeds, which is useful on a failing but not dead drive. But dd_rhelp will do the same thing, for free. To read a bad block, SpinRite will try tricks like seeking to adjacent cylinders/heads/sectors and back again, in various directions. This was plausible for ancient drives, but everything made in the past 20 years or so has abstracted the real disk geometry away from the host, even when presenting "CHS". So these tricks are meaningless on anything that isn't old enough to run for congress. And, of course, SpinRite is from Steve Gibson, who always talks like an infomercial host. Billy Mays could have taken lessons from Gibson. Gibson claims SpinRite "interfaces directly to the hard disk system's hardware", which somehow gives it magical abilities. Everything I've seen suggests this is an outright lie. SpinRite flat-out won't work if the drive isn't presented using BIOS interrupt 0x13. He claims things like "hardware register level awareness of IDE and SCSI drives". SCSI drives *don't have hardware registers*. The SCSI spec is quite abstract and hides all that stuff. Further, you don't talk to a SCSI drive, you talk to a host adapter. You literally *cannot* talk directly to the drive. You can, however, request additional sense data and mode pages, which provide a wealth of useful information about the drive. In the DOS environment under which SpinRite runes, this is done through the ASPI interrupt calls. It's a useful capability, and I expect it's what SpinRite does, but it isn't the Amazing Scientific Breakthrough!!!1! Gibson claims it is. He just Read The Fscking Manual and learned how to use ASPI. I do think SpinRite did things other software wasn't doing, at the time and place it was introduced in. Even something as simple as pattern testing wasn't common in the dark ages of DOS. (Other platforms had it, but the IBM-PC was the ghetto of the computer world.) I acknowledge that. It was valuable at the time, and even today, I suppose a nicely-presented, integrated package might still have value. But that doesn't mean Gibson's bullshit doesn't stink. Regardless of the efficacy of SpinRite, Steve Gibson is in way over his head when it comes to security. His habit of being uninformed and making stuff up has burned him more then once. </pre> Ben Scott 2013-04-28T15:19:08 http://comments.gmane.org/gmane.org.user-groups.linux.gnhlug/22503 <pre>There used to be a site out there that was like "geektours.com" or "engineeringvacations.com" or something like that.
