Agh. This is great to have some of this clarified, Ted. It does unfortunately reinorce my cynicism. But it also fills my heart. That is, though it might be bad news to hear that I have most likely bought a piece of crap, and that there's no way I can really tell what's inside the cover unless either I do some kind of low-level alchemy of a kind that mere users would normally be well

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everyone, I been using CF cards for almost more then 7 years now with ext file-system without any major problems on ALIX boards. Last year I took 30 other systems in production with ext4 and the CF cards been dropping out pretty fast, it may have been a bad batch but I do want to look at it. I don't think the devices writes a lot of IO (is

I know this may be a stupid place to ask, but I have to ask. I'm looking for a new Linux distro to use and support. I've been a loyal purchaser of SuSE Linux Pro for the last 3 years. I've paid my $90 loyally, in part because I wanted money to actually go to someone working on OSS, but also because I thought it was a good bargain, to get a quality, tested distro for that cost. The

Have software producers asked them for this? No, they haven't. And yes we have, since

I have the following HAML code ul{ ''id'' => tutorials_ul } %li %a{''href'' => ''/videos/create-command-001.swf''} ''Edition swf'' %li %a{''href'' => ''/videos/create-command-001.flv''} ''Edition flv'' When the user clicks on

Something else that you might want to do is count the number of journal commits that are taking place, via a command like this: perf stat -e jbd2:jbd2_start_commit -a sleep 3600 This will count the number of jbd2 commits are executed in 3600 seconds --- i.e., an hour. If you are running some workload which is constantly calling fsync(2), that will be forcing journal commits, and those turn into

I''m looking to try BTRFS on a SSD, and I would like to know what SSD optimizations it applies. Is there a comprehensive list of what ssd mount option does? How are the blocks and metadata arranged? Are there options available comparable to ext2/ext3 to help reduce wear and improve performance? Specifically, on ext2 (journal means more writes, so I don''t use ext3 on SSDs,

I''ve got two recent examples of SSDs. Their pristine state from the manufacturer shows: Device Model: OCZ-VERTEX3 # hexdump -C /dev/sdd 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 1bf2976000 Device Model: OCZ VERTEX PLUS (OCZ VERTEX 2E) # hexdump -C /dev/sdd 00000000 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| *

Hi We have a number offices accommodating 4-6 people each hence it is very important for PBX to be fanless and silent. We have been looking at using IDE flash disks also called DOM. The performance tests we have done so far satisfy our requirements, however we are concerned with DOM durability. We have installed debian and vanilla asterisk on 1GB DOM. All seems to work fine at the moment however

Hello! I'm using a CompactFlash as storage device. Since those CF cards only have limited write cycles (CF does wear-levelling by itself, but you don't want to write too many timet so the card) i was wondering by what a factor the journaling of ext3 increases the write accesses to the CompactFlash compared to ext2. Thanks a lot already for your help! Sincerely Chris Braun

In case anyone still cares, relay-ctrl works with Dovecot. Dovecot's end of the bargain requires a dirty little script to set TCPREMOTEIP based on the arguments passed from imap-login: #!/bin/sh TCPREMOTEIP=`echo "$@" | sed -e 's|.* ||' -e 's|]$||'` export TCPREMOTEIP exec "$@" And this (long) line in dovecot.conf: mail_executable: envdir

>From the little I have heard about control systems for cars, which was some years ago, they were blockhead proprietary. The analogy would only work if computing was customarily blackbox technology, which it isn't. I'd be surprised if there were any branded flash drives that contained less than their advertised amount of storage. That leaves the question of what is going on under the
