"today's IDE drives are significantly faster than SCSI drives".
Fastest ATA drive at the moment transfers up to almost 50MB/s near the begining of the disk, fastest SCSI drive transfers at 60MB/s near the begining.
The SCSI drive has a measured seek time of 3.9mS whereas the ATA drive has only 8.9mS.
Factor in SCSI abilities to be able to queue commands, automatically re-order them and use the bus for more than one thing at a time and you'll see that SCSI is still the fastest. Especially so for IO intensive applications where lots of small transfers are requested.
Whether the price difference is worth it or not for your application is what really matters.
The Western Digital Caviar WD1200JB is one awesome ATA drive though.
Kelby is dead-on about many things, like how computer store personnel are mostly clueless
Yesterday, I was in a computer store and over heard a sales guy say to a customer inquiring about RAID, that "Seagate drives don't work in a RAID setup, because they're just too fast. Trust me, I know, I've tried at home! I've spoken to Seagate about it and they acknowledge the problem." He also stated to the customer that Seagate does not make anything else but hard drives.
I was'nt really in the mood to interupt and tell of my RAID setup at home that has been working nicely with Seagate drives for about 3 years now.
Sometimes helping out other customers with correct advice in the presence of these nit-wit sales types can be fun though.
Yeah well all the USR's I ever had were the wrong revision or had something other excuse and I couldn't flash me haardware without a upgrade or to buying a new modem.
yeesh! USRsucks
Yeah well, they did also make WinMODEMS. They need to be able to compete on both ends of the quality scale. Just because they also make some cheap junk does'nt mean they're no longer capable of making great products.
My USR Courier V.Everything cost me about 600 Aussie dollars, so you pay for quality like this.
Pay next to nothing for a MODEM then expect to have to upgrade when the next MODEM technology comes along. Although, having said this, PSTN speeds should'nt be getting much past V.92, considering the digital limit (if we could ignor artificial bandwidth limits and bandwidth loss thru DAC/ADC) for each line with PSTN is 64k.
My USR Courier MODEM, now being about 7 years old (my model) was first a V.34 28.8k MODEM, then upgraded to V.34bis 33.6k with a simple firmware download, then X2 56k, then V.90 56k and now it seems, after 7 years, it will be upgradable to V.92 soon.
With an Intel 80186 20MHz (25MHz for US model), TI DSP, flash memory, etc, it is one heavily over engineered beast of a MODEM.
Does'nt surprise me that the company to get extra performance out of a technology, is USR.
With OpenBSD, you have choices. Install via ftp for free, download one or many platforms to burn as bootable CD's, purchase official CD's, etc.
If you're friends can't figure out how to get or burn a bootable CD for their arch or install from ftp, maybe they ought to be looking at Mandrake Linux or something.
I love Debian, but I also hold 4 years secure in much higher regard than 4 days secure.
They're a team that gets little attention compared with Linux, so they need some sales to support them. If Theo wants to distribute some Copyrighted CD's and you don't like it, then just don't buy them! But please don't complain about it. He's well within his rights to do it and you ought to be happy that you can get unofficial CD's, ftp downloads and installs, etc.
The OpenBSD team doesn't ask for gratitude, they ask for money and they ask for everyone to act in accordance with Theo de Raadt's claimed copyright on the CD layout. I have provided both.
Any moron can download as many or as little in terms of supported platforms, from the OpenBSD ftp site and then make bootable CD's from that.
Not a problem in the eyes of any of the OpenBSD team, including Theo.
The only thing he does'nt want, is for people to copy the CD's he has already provided as the official CD's. Big fucking shit.
If you want to be sure that you're getting the most secure OpenBSD distro, then purchase the real CD's. ftp sites get hacked from time to time and copies of "official" CD's can be just about as trustworthy.
I also use Debian, BTW.
The team does NOT ask for money to download as much as you want from the ftp sites. Hell, they even provide floppy images to be used for making bootable CD's! They don't have to ask for gratitude, any moron can see that they deserve it. The copyrighted CD layout only applies to the offical CD's.
That's not quite right, according to what I was told by people on the OpenBSD team.
The layout of the official CD images are copyright Theo de Raadt. There is a copyright on the back of my 2.8 CD case and I beleive I saw these on each case from 2.5 on (when I started using OpenBSD).
The official CD's tend to have many supported architectures on them and some discs can boot from multiple architectures. Theo would have to have gone to a little trouble to achieve this and I don't see how preventing people from just selling exact copies of the official CD's somehow hurts the community.
If all you use is OpenBSD i386, then just ftp/wget/rsync the i386 tree and then burn your bootable i386 CD. It's real easy and the download for i386 (3.0) is just 120MB, not including source. Or just ftp install it.
I download macppc and i386 to get the latest versions as quick as possible, but I also purchase CD's and soon a bunch of shirts.
So he does'nt want people distributing copies of the official CD's. Big deal. People who want to run OpenBSD on TEN different platforms can buy the CD's.
People like myself, who want to support this great project, can always just purchase stuff from the team.
Thank god that all of us here at Slashdot don't ever badmouth or try to undermine Microsoft. Those bastards.
As if money hungry, crap software making Microsoft somehow compares with the honourable intentions of the OSS community, who, comparatively speaking, make rock solid software?
MS charges like a wounded bull for XP for example, now compare it's stability, cost and creator intentions with Debian.
A nasty remark against MS from a geek, is founded in truth and completely warranted. MS has been making shit software and been using illegal tactics for many years, they spread FUD all the way and actively try to squash all opposition, yet geeks complaining about this are somehow as bad as them? Get real.
A similar remark from MS against Unix in general (with intent to simultaneously umbrella Linux, Sun, SCO, Apple, the BSD's, etc) is plain dishonourable and unfounded.
Just look at the power adaptor. 9V at 300mA. Thats 2.7W.
Try to get 10W out of that plugpack and you're gonna melt it.
I was tought, if I can remember correctly back 14 years, that PMPO was measured from the peak of the positive most point of the signal, to the peak of the most negative point of the signal.
Whereas RMS is measured between the 0V cross over point to 0.707% of the peak of a sine wave signal.
So a 20W RMS amp would be 56.6W PMPO? Which they'd probably advertise as 60W anyway.
BTW, I agree with you wholeheartedly, Re: your general gist, etc. I hate P-bloody-MPO bullshit. My 30W RMS Sony mini Hi-Fi is *really* loud for me.
Years ago, I wanted a Pioneer M91 power amp. Awesome specs and 200 Watt RMS per channel. As you say, it was heavy. : )
When spammers don't use BCC, and instead have a large list of emails To'ed or Cc'ed, I like to reply-to-all, defaming their "products", pointing out what they're selling is either crap, illegal or just plain does not work.
Sure, I get lots of spam, but I was getting plenty before that anyway. I think I must be on every fucking mega email list out there.
I purchased OpenBSD from 2.5 to 2.8, until I suddenly became too poor to pay 50 Aussie bucks for the official CD's and found out how easy it is to make my own bootable OpenBSD CD's for just what I need...
If you want x86, then just download it from the OpenBSD ftp site.
wget -r ftp://ftp.openbsd.org/pub/OpenBSD/3.0/i386/ Makes it easy.
Now though, I'm no longer terribly poor and want more than just x86 (I want x86, Sparc64 and Alpha), so I'll be buying lots more official CD sets and T-Shirts.
I was considering making an analog system occupancy meter months ago. It would be really easy too, through the parrallel port.
Periodically write the occupancy to the parallel port, which could have a super-simple (tm) R2R digital to analog convertor (appropriately built for the low voltage requirement) hooked up to an analog meter.
Last time I was experiementing with lpt ports, 10 years ago, the data was held on those lines until the next byte comes through, so no latch should be required.
IMO it's better to get a 1gb harddrive to install the full freebsd distribution, not only a kernel and some stuff, because you'll have a lot more possibilities to play around with;)
And so will the hacker who roots your firewall, thanks to all those possibilities. ; )
IMO, get a cheap 32MB Compact Flash card and IDE adaptor, install emBSD and watch them try to root it.
With firewalls, small is best. If you're running any services beyond perhaps ssh, or have non firewall critical binaries or compilers lying around, you're asking for trouble.
Linus' hypocrisy matters because if the guy went to the trouble of stating how it should be said, then says it does'nt matter how it's said, fools like us will end up arguing about something that should not matter.
What I hate is being told how to do something by someone who's never done it right. I don't care if they go their whole lives doing it wrong, but if they tell someone who does do it right, how to do it, then I'm annoyed.
There is no such thing as "proper" pronounciation, and to claim otherwise is arrogance.
So effective communications is not important?
However, Line-Icks barely compares to Mac OS version Ecks. OS NINE plus ONE, is OS TEN.
OS Ecks is just downright silly for the successor to version 9.
Linus has been VERY contradictory in what he says on many occasions. Recently in an interview, he said (loosely quoted) that he "has barely even looked at FreeBSD or Win XP", yet in the next breath says "but I see nothing worthwhile in those OS" or some such crap to that effect.
Can you get any more arrogant than that!? And if the guy could'nt care less about how Linux is pronounced, then why the fuck would he release an au file in the first place saying "HELLO! This is Linoos TOR-valds! And I pronounce Linooks, Linooks."?
You are claiming that you magically know more about how to pronounce software than its creator.
Bullshit. I am saying that I hate arseholes who argue the point about such stupid shit when they barely know how to use what they're arguing about.
OK, if you wanna call OS X "Oh Ess Ecks", then you will be in good company with all the new Linux "experts" that have suddenly popped up, who pronounce Linux "Line Icks".
I've actually had one of these morons *correct me* because I say "Lin Ucks".
Guys who could'nt fight their way out of a lilo.conf file.

Sorry, I was only speaking of bit depths in general for current variable or future algorithms that support those high bit depths.
I was thinking of adding "this assumes the algorithm can realise the full...blah blah"
Or move to 4096bit.
9 999E499 (which it also says for 2^1661, which seems to be the overflow point).
Don't forget, every bit added, doubles the strength.
4096 != 1024*4
My HP 48GX says:
2^1024=1.79769313486E308
2^4096=9.9999999
4096 is 2^3072 times stronger

"asshole", not "arsehole"
Australians use the latter. So, the lead guys behind Samba and Enlightenment are child molesting retards? You're the fucking retard.

It is those arrogant idiots that I hate. I hate the people that do something incorrectly and then *correct* someone who does do it correctly.
But I don't EVER correct people that say "Line Icks", not even the arseholes who correct me.
I replied with a little sarcasm because, if people are actually going to argue against proper pronunciation then they're the arrogant idiots.
BTW, the guys who do correct me are ALWAYS the types that would'nt know a lilo.conf from a raidtab.
It is not I that is arrogant.
As long as /. doesnt do pop-ups, i can handle the ads.
I've just started using Opera for Linux (TP2), it has a "don't accept pop-ups" feature that actually seems to be working.
