Try:
printf("long long NN = %16llx\n", NN);
For longs, long longs, etc. you should specify the correct length
modifier to printf, so the three lines quoted above should be
written as:
printf("long int N = %16xx\n", N);
printf("long long NN = %16llx\n", NN);
printf("long long NN = %lli\n", NN);

In that case, something odd is happening here, because this was literally hundreds of packages, including the kernel-* packages. fc8 was on kernel-2.6.26.5-28, fc9 has kernel-2.6.25-14.

Re: Laptop external power from batteries (DC/DC)

Car battery manufacturers don't typically advertize amp-hour ratings because you don't really care about that for a starting battery; all you really care about there is the CCA rating. Also, the math really isn't as simple as what you are doing. Those amp-hour ratings are at a specific current draw--if you are drawing at a higher rate, you'll get less out of the battery (Peukert Effect). Typically for a deep-cycle battery the amp-hour rating is for 100% discharge over 20 hours, though some manufacturers rate over 100 hours to make their batteries look better. So, presuming your 100Ah battery above is a 20-hour rating, it will provide 100Ah at a constant discharge of 5A. Since you want to draw more than that, you'll get noticibly less than 100Ah. Without seeing specifications for that battery, I'd anticipate a 10-20% drop in capacity for the 50% higher discharge rate. So, ~10-11 hours, not 13. That's to 100% discharge, which does damage the battery. Of course, that presumes your equipment will operate on the battery at all states of charge, which is likely not to be the case. Below about 50% charge on any 12V LA battery, the voltage will be <12V, and your adapter (which was probably designed with the expectation of being attached to a runing car, at ~14V for the nominal 12V system) may not be able to cope. So, presuming your adapter needs >=12Vdc to operate, that 10-11 hours becomes more like 5 hours. So far, all of these numbers are based on 100% efficiency, which isn't realistic. A good (and sadly, expensive) DC-DC voltage converter is only about 85% efficient, so to get the 19.5Vdc @ 4.62A you need, you will draw ~8.63A @ 12Vdc. ~5 hours becomes ~4.5. > I know if one was planning on doing this on a regular basis, a deep > cycle battery would be highly recommended. For a one-shot, though, > pulling the battery from a car might be feasible (?). I wouldn't do it. Definitely don't do it if you need that battery to start the car to get you home after the event. Car batteries are designed to supply a very large current for a short period of time. They are not designed for continuous draw, or to be deeply discharged; doing either will severely reduce the lifespan of the battery, and may kill it outright. The thin lead sponge used in these batteries to maximize surface area (and therefore current) is easily damaged by deep discharge. For maximum battery cycles, don't discharge more than 5-10%. Deep cycle batteries have much thicker solid lead plates, which gives less surface area (and lower maximum current), but these plates will not crumble on deep discharge. You can discharge a good deep-cycle battery to 50-80% without harming the battery. If you're going to do this, save yourself a lot of headache and buy/borrow a deep cycle battery & charger. You'll need a pretty big one for the load you're talking about, one rated for 250-300Ah. More if you need to use an inverter, to account for the extra efficiency losses there. A portable generator might be easier, if a long outdoor extension cord is not possible. -- [EMAIL PROTECTED] OpenPGP KeyID 0x57C3430B Holder of Past Knowledge CS, O- "There is nothing useless in nature; not even uselessness itself."

That said, you can approximate the result by playing games with hard links. Without real copy-on-write support in the FS, you do need to keep an entire second copy of the data on-disk, though, or some file changes will modify your 'backups'. I use this method for keeping daily snapshots of our mail store around for a few weeks, to make restores easier (fscking scalix requires a complete copy of the mail store to extract even a single message for restore, which is nothing if not a massive PITA). All of my filesystems are on LVM, which makes it easier. The basic procedure is: 1) briefly supsend filesystem writes 2) make an LVM snapshot of the source filesystem 3) resume filesystem writes 4) mount the LVM snapshot 5) use rsync with the --link-dest option to make your new snapshot copy 6) umount the LVM snapshot 7) remove oldest rsync snapshot copy 8) I forget what 8 was for If you've never used the rsync --link-dest option, here's an example: Say you have two filesystems, mounted as /data and /snapshots. /snapshots is a bit larger than /data, to allow for storage of multiple snapshots. Snapshots are taken hourly, kept for 7 days, stored in subdirectories of /snapshots named with a timestamp in -MM-DD-hh format. Your last snapshot was taken at 1400h on 2008-07-23, so to run the snapshot at 1500h you could use a command like: rsync -oa --stats --delete --link-dest=/snapshots/2008-07-23-14 /data/ /snapshots/2008-07-23-15 This command will create the directory /snapshots/2008-07-23-15, and run an rsync copy from /data/ using /snapshots/2008-07-23-14 for comparision. Any files that are unchanged from /snapshots/2008-07-23-14 will be stored in /snapshots/2008-07-23-15 as hard links to the copy already stored for /snapshots/2008-07-13-14, while new or changed files will be stored normally. That should achieve most of what you're looking for, using as little additional storage as possible. How big to make /snapshots (best to keep it on a separate filesystem, IME--I also like to put the /snapshots filesystem on cheap SATA NAS (iSCSI) disk, instead of on the fast SAN disk we use for primary storage), depends on how much of your data changes, how often it changes, and how many snapshots you want to keep around. In my case for a ~1.5TB mail store with about 50GB of changes daily, I'm comfortably storing a months worth of snapshots on a 3.2TB filesystem. -- [EMAIL PROTECTED] OpenPGP KeyID 0x57C3430B Holder of Past Knowledge CS, O- History doesn't repeat itself -- historians merely repeat each other. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

I'm pretty sure FVWM 1.x still compiles on recent distros. It will, but it is a minor pain to do. I've had to write several minor patches to work with modern libraries. The "big" problem is that some idiot renamed the 'fvwm2' packages to 'fvwm' in FC5 or 6, so if you do a 'yum update' it breaks your window manager until you figure out what went wrong.

There is almost no chance that you'll get those batteries to take a charge at all, if they were drained that low. As you're probably aware, each of those 12V batteries is made of 6 2V cells. Fully charged each of those 2V cells is good for about 2.15V, fully discharged is about 1.75V (for good, working cells). Generally speaking, if a 12V battery with no load is reading below ~10V, something is pretty badly wrong with the battery, usually a short across one or more of the cells. >From what you're saying, you're reading less from the entire battery than a single "discharged" cell should provide, so I'm going to go out on a limb and guess that these batteries are pretty old, and heavily sulphated. You may be able to salvage the battery well enough to start the UPS by running an equalization cycle on it, but that is somewhat tricky/dangerous with a sealed battery as you're *trying* to overcharge in order to boil the electrolyte to break up the sulphation on the plates. > Te battery was sitting, hooked-up, inside the UPS for I dunno how > long.

The only thing to "worry" about is that you don't try to charge too quickly, as that can generate excessive heat in the battery, causing the electrolyte to boil, which is a bit of a problem in a sealed battery. For batteries as small as typically used in a UPS I wouldn't charge at anything over 2A. -- [EMAIL PROTECTED] OpenPGP KeyID 0x57C3430B Holder of Past Knowledge CS, O- "At first I thought, 'How could women be from Venus?

As others of mentioned, that depends on the battery chemistry. Note well that "sealed lead acid" doesn't necessarily mean "Gel". It could be an AGM battery, which will charge just fine with any decent PbA battery charger. OTOH, it sounds like the battery is already pretty well fscked, so even if it is a Gel battery you aren't likely to make things worse (using a standard charger on a Gel battery will not charge very well, and will certainly reduce the lifespan of the battery, but it isn't likely to explode unless something else is wrong).

Say you have three sub-lists: gnhlug-chat, gnhlug-politics, and gnhlug-tech. If gnhlug-discuss is subscribed to all three, postings to any of the lists also get posted to -discuss. All of these lists are restricted to only allow posting from subscribed addresses, to cut down on abuse. So far, so good, that *seems* to be what we want.

Ben never sees Joe's reply, because Joe's mail is stuck in an approval queue for unsubscribed postings. Joe has a question, which he posts to gnhlug-discuss since that is what he has subscribed to. Unfortunately for Joe, most of the GNHLUG community never sees his question as they have subscribed to the sub-lists they are interested in. Everyone loses.

Or do we start both > lists empty? I have been through this a few times in the past, with different groups, where the decision was eventually made to fragment the list into multiple lists with more focused charters. I have, to date, never seen it work well. With one exception, all of the mailing lists I have seen fragmented this way have either reverted back to a single main list (sometimes with a separate, often moderated list for announcments, like we have), or gone away entirely. That one exception had strongly focused charters, very clear lines on what topics were appropriate on which lists, and a large team of volunteer list-cops (over 50 when I was in charge of managing them) to keep things on track and ban chronic offenders. They did not have the proposed bad idea of subscribing each of the sub-lists to another list to form a combined list. Even there, the off-topic posts remained, and there was the additional problem of posts being sent to the wrong list, or crossposted to multiple lists. They stuck with it, at the cost of enormous volunteer churn, and lost a large chunk of their membership, myself included, when the "transition grief" was still increasing more than a year after the actual transition was made. I *STRONGLY* believe that this sort of change would be bad for GNHLUG in the long run. Consider how successful the various mailing lists for the local chapters have been. Consider how troublesome trying to keep the job postings on the gnhlug-jobs list has been. Consider how successful the "linux cafe" list, created in response to exactly this complaint back in 2005, was. Does anyone really think this particular division will be more succesful than either of those?

It does not. "regular file" means not a special file, directory,
named pipe, symbolic link, or socket. "plain text files" are a
subset of "regular files". If you just want to omit non-text files
from the output, something like:
find . -type f -name '*out*' -print0 | xargs -0 grep -wliI zip > zip.txt
will probably do what you want. The -I option to GNU grep tells it
to treat binary files as if they contain no matches. The -print0
to find and -0 to xargs improve handling of file names that contain
whitespace.

If you run 'find . -type f -name '*out*' -print0 | xargs -0 file'
I bet some of the files you are calling "plain text files" are not
"ASCII text files", which is what the above is looking for. For
example, a file 'file' reports as "ISO-8859 English text" will
almost certainly meet *your* critera for "plain text", but doesn't
include "ASCII" anywhere in the output of 'file'.

Basic interoperability was pretty much non-existant when I first tried it, the PIM apps for the Zaurus weren't available in any desktop form I could identify. I quickly gave up and just made regular backups to a spare CF card.

(Is > that the difference between DVI mode and not DVI mode?) Either way, I DVI allows you to send a digital signal directly to the panel, without converting digital to analog and then back to digital. If you are using a standard d-sub 15 VGA connector (3 rows of 5 pins), you are operating the panel in analog mode. Nothing wrong with that, but you are almost certainly introducing some noise in the analog stage, so the display isn't going to be as crisp as it could be. A DVI connector is bigger and more square than a VGA connector and has more pins. The various connectors look like: http://en.wikipedia.org/wiki/Image:DVI_Connector_Types.svg If you have video hardware capable of DVI, and the monitor accepts DVI input, you will almost certainly get a better image on the display using DVI. Either way, your X configuration doesn't change, unless your video hardware has multiple connectors and you need to add configuration to select which one(s) to output on.
