but does this really count as ONE BIG SERVER for each game? if not, what is the advantage to having a single-entrance point of failure for the whole lot, when you could just use multiple independent servers?
That is, 12749 POP3 sessions took 32.42 minutes of CPU time (on a 350 MHz Pentium II); of those, more than a half was spent in the temporary child processes. It's not that bad though, as this system was running an (intentionally) expensive crypt(3) that got accounted to the child/etc/shadow authentication processes.
Before upgrading to popa3d, the same machine was running qpopper (out of inetd, too):
12025 3169.38re 35.56cp popper
It used to take a bit more CPU for less POP3 sessions.
the project is not commercial, and has no dreams of having millions of users. it only seeks to do what it does well - which it has for some time.
most of the users and all of the developers would probably scoff at the idea of upgrading the installer because development resources aren't cheap, and they feel the time would be better spent elsewhere since the installer does work just fine.
the 'rustic' install (complete with MANUAL PARTITIONING!!!) serves as a barrier to entry, keeping the mailing lists more clean of 'how do i mount a floppy?' questions.
this information is bad, as the 3.2 snapshots are now further ahead in development than the 3.2 release code. there is no supported method for backtracking from -current to -release.
for the impatient, the best method is to check out the 3.2 sources from cvs (as described) and build from source
the 2600+ got announced a long time ago, but the last FOUR amd cpu release have been paper launches where the product came out several weeks late.
the athlon xp 2600 oem cpu is not available anywhere outside of pre-order, and its lowest listed price on pricewatch is $285 - oem, 30 day warranty, no heat sink/fan.
the password won't need to be transmitted if he does the buddy list thing, so he's only worried about the output he actually sends leaving the host pc before it gets to the isp.
mobile access - mobile phones with aol instant messenger built-in
he could have the commands be run as a non-privileged user, and sniffing shouldn't really be a concern; he could have the target system only allow messages from people on his buddy list, and add his 'special' user to it.
you can do this same thing in a tiny cube with a shuttle ss51g. the only fan in the system is an 80mm case fan, and it would accept a p4 2.8/ti4200/etc.
Supports writing 99min CDs 4 Speed DVD-R Support 2 Speed DVD-RW Support Supports DAO-RAW mode Higher DVD read speeds for DVD-ROM & HS media Lower access times Can read and write 96 bytes sub-channels Fast & perfect audio ripping Can produce X-Box & Playstation compatible disks Can read & write CD-Text DVD "-" offers better compatibility with older players Low cost of ownership

Pioneer has finally delivered on what we and most others wanted most in a DVD writer and that was an increase in DVD recording speeds. There is no disputing that the speed at which new DVD writers record to DVD-Rs at is light years ahead of the 1st generation drives - the A05 only needs 15mins to writes a whole 4.7GB of data.
We were slightly disappointed with the A05's CD writing ability, mainly its CD-R maximum writing speed of 16 X and its relatively slow re-write speed. It's interesting to note that the preliminary product specifications show that Pioneer had faster CD recordable features and higher DVD-ROM read speeds in mind but decided against implementing them.
We were pleased that Pioneer added support for writing in DAO-RAW mode - a useful feature used by Clone-CD for backing up games (in countries that permit it). This addition isn't all that it appears to be as its performance was so bad that it's pretty ineffective - it failed to backup any of our games and took long time to read them!
The A04 was particularly good at reading and writing 99min CD-Rs and was one of the best performers for that specific test - the DVR A05 does not follow its lead unfortunately. It can write to 99mins fine but when it came to reading what it had written it had severe problems (this was verified with disks that the A04 had produced).
One of the major improvements that we noticed with this drive was its random access times for DVDs - they are so much faster than the A04 and you wont be disappointed if you'r used to handling many small files.
The 4X DVD recording is an incredibly nice feature to have but unfortunately we didn't get to test it as 4 speed DVD-R and 2 speed DVD-RW disks are not out here in the UK and this is a PRE-RELEASE unit we have reviewed, but we hope to re-test the DVR-A05 with a full retail version if/when the opportunity arises.
The drive had major problems when reading CDs, whether it was a CD-ROM or CD-R it was incredibly fussy and slow. The access times for CDs was good but the transfer rate was slow for everyday use. This is an area where even the older A04 is better at.
With a price tag of £249.00 we feel that Pioneer may have been beaten at its own game by the likes of Sony, Philips, Panasonic and Sanyo who are all due to release 4 speed DVD writers (Sony have already released the DRU-500A in America) with faster recording speeds and more features. The A05 has its work cut out and our advice is wait and see what the competition offers.
ok, so if i disagree with pushing people in front of a bus, i should just stand there and watch if somebody pulls out an uzi on a street corner and gets ready to mow a crowd of bystanders down?
his ethical line is drawn independent of the details. in this situation, HE HAS THE DETAILS. failing to use them in his decision-making process would be retarded (as would the above-mentioned example). the top post is valid.
> does anybody know if either tree in the last couple months had trojaned code > in it, exploiting make builders?
Not affected. When I committed sendmail 8.12.6 the tarball I fetched was not the trojaned one. Even if it had been we probably would not have been affected since we don't use sendmail's build system (which is where the trojan was apparently inserted).
there was a single DoS one that i know of, but other than that no exchange 2000 exploits exist. i've never heard of a total remote access exploit for 5.5 or 2000.
outlook web access / iis is the only source of problems, but that's all iis' fault.
if there were sufficient demand for COMMERCIAL ENTITIES (e.g. red hat) to support 5 versions, they would do it. that's because they have the money to throw resources at it.
openbsd could offer to support 5 versions too, and that would place forward development at a virtual stand-still because of the overhead required.
when the world needs that level of support from red hat, they will have it. that level of support from totally volunteer-based projects will show up WAY later.
as an aside to all this, openbsd simply isn't the kind of os people put on 850 machines. if there's a single grouping of 500 somewhere i'd still eat my hat. it's not a performance/clustering os, it's an edge/internet server os. even if it had exponentially greater development resources, the focus would likely still be on the future as opposed to the past because farms of it simply don't exist.
i have a single master system that builds a release distribution and publishes it to a private site. i run the following script to do an in-place binary upgrade of all my systems:

flamebait? right, idiot.
