I've heard of using the outer cylinders for speed (because of their larger capacity and faster transfer rate) but not the inner cylinders.
Tom's review of the 2.5" Savvio shows that while its overall performance as a workstation drive suffers from exactly what you say, for database benches it surpasses a 3.5" 10k rpm drive. For database (particularly OLTP) use it's I/Os per sec, especially with 2k or 4k writes. Sequential transfer rate is not as important in that application.
Varying speeds usually causes random access delays since it takes time for the new speed to settle when heads are moved in/out on the disk. The momentum of the motor and platters is huge compared to that of the heads.
Reduce the mass and area of the media and boost RPMs, and possibly add multiple heads per platter (internal striping). DB heads would rejoice. And it's DB heads that pay beaucoup $$$ for SCSI or FC-AL arrays.
(Folks doing media work like video or rendering that need sequential can go for stuff like Xserve RAID with SATAFC-AL and stripe sequential bandwidth...)
... I can guarantee you most DB guys I know would shit their pants in joy if they could get 15k RPM 9GB drives in bulk. I know of DBAs that buy 18g drives and only use half of them. In theory you only use the inner cylinders, but internal geometry these days is largely divorced from logical geometry.. DBAs who deal with random small writes want lots and lots of spindles striping using lots and lots of hardware RAID adapters.
The super exciting thing about the 2.5" drives IMHO for SCSI is the possibility of boosting rotational speed thanks to reduced media weight. If you could get 1" 20-40kRPM 9GB SCSI or SAS drives and join together 100 of them that would be unbelievable.
Being able to do all of these things from a web browser is definitely a nice parlor trick, but in reality it's not a very easy way to use a computer. The real power of these protocol handlers is unleashed when they're used within various KDE applications. Any of these protocols can be used from the KDE file dialog, allowing files to be opened from or saved to any protocol!
I must say, as much as I don't really like KDE, that's really slick, and potentially very useful. Nice job guys.
BTW, if you have the 'run' CLI (Application Launcher) in your kicker bar, you can type all that stuff there, as well as konqueror shortcuts.
So, instead of clicking on a konqi browser, going to google's image site, typing in search params and hitting submit, you can type the following into your run bar:
ggi:donkey porn
hit enter and a konqi browser pops up with the search loading.
or, instead of opening a shell and typing 'man find', go into the run bar and type:
man:/find
and you get a konqi browser that loads and prettifies the nroff manpages, including linking to any other specified manpages.
Hell, a konqi kicker bar doesn't need app icons at all, just a K menu, Application Launcher, and all the other toys (like the RSS KNewsTicker, clock, X display res thingy, kalendar, kgpg, kwallet, etc)..
I have to say that if Stern took a cheap shot, Powell acquitted himself quite well in the reply.
I'm also somewhat of a Powell fan on balance. He seems a bit more savvy about things like VoIP than most FedGovBots. Granted, I would prefer that he preempt any local monopoly-granting power to telcos, but that'll probably come after we take farm subsidies to the back of the shed.. (shortly after hell freezes over:[)
Without static IPs and with draconian TOS, I'd only be interested if they could offer a good competitive 'cable' service to Time Warner. That is to say, assloads of channels + broadband for $80/mo instead of $100/mo.
Then again, it'd probably take another 10 years to fibre up NYC, so I don't care.
Very cool hack. I wonder if Griffin would consider starting building keyboards with integrated knobs, alongside or in place of numeric keypads?
I also wonder if there's any interest in mapping, say, a row of toggles to stuff like this. Literally switch from desktop 01 to 11. This kind of goes to the whole 'antiquing' fad that has folks building mini-itx gramophone players/iceboxes/televisions, fitting bakelite handsets to cellphones, etc..
Another interesting hack would be to have two knobs and run the pointer like an etch-a-sketch. It'd be ten out of ten for style but minus several million for good thinking..
My main point is that the MTA is becoming more arbitrary and can't be matched against the "From:" header. It's not a bad concept, but it has too many holes to be used as presented.
Exactly, which is why we need to do one or more of the following: * have domain certs for legitimizing domain MX recs using a new MX key RR, and putting those RRs into standard DNS and/or running a 'trusted' whitelist DNS that has those RRs * have mail clients that can use certs to sign mail regardless of ISP, with support on the MX side of that (dialup/broadband) conn to vet and forward. * use SMTP AUTH over SSL to provide legit relaying (quickest and most convenient fix for travelers) * use a system where a host will relay if a msg's signed crypted hash verifies when decrypted with the domains legit MX key. Clearly, that may end up being the functional equivalent of a DOS attack, but it's a possibility particularly for ISPs that enable it on client-facing ports.
There'll always be a call for anonymail SMTP, but it doesn't bother me that we assign a trust rank to it, like not picking up the phone for 'out of area' caller id.
What about SMTP-authentication? Why not use the SMTP service for whomever your email address is through? Many ISP's, in retaliation to spammers who used open relays, blocked outbound connections on port 25. Oops, that won't work.
SMTP AUTH over SSL. Works like a charm. You need an ISP or service competent enough to configure it though.
What about users who travel? I have a laptop; at home I use one provider, at work I use a second, when I travel I use a third. I would have to configure three "From:" headers dependent upon which ISP I was using.
See above.
The interesting thing with 'autonomous' vanity domains is having support for 'legitimate' MX records in DNS, so a particular mail server configured with a particular cert that matches DNS (making it or someone's particular DNSSEC an authoritative source) fictional MXKEY entry. Or, failing that, use such a key with a compatible client that can put on a X-header with the signed hash of the contents.
There's an RFC that limits putting keys into DNS records to DNSSEC related keys. However, according to one of the authors of that RFC there's still spare RR numbers that could be used for MX keys.
This trumps M$ to some extent because you could designate a number of authoritative DNS servers (as with RBLs) that can have multiple CA capability so you could buy certs from, say, the USPS, UN, Verisign, whoever you want to make canonical. And it'd be competitive, rather than have a single point of taxation.
Steve Jobs really pissed me off when he canceled the Newton, to this day it has the best handheld UI bar none. I think it could have been huge (no pun intended) if it had survived long enough to add smaller and larger formfactors, color, wireless.
I seriously doubt he foresaw the whole pda/phone thing, like the P800, Treo, E680, etc. But, I think he has a point when he talks about how the stuff we need to do with an organizer (todos, events, calendaring, contacts) can be done in a phone.
I think the main problem with that though is changing wireless standards, frequencies, etc, which require software radios.
... After 1996 or so A&B were _the_ reason to buy Computer Shopper, unless you had a decent computer show in your area and could get a good selection of hardware.
Most computer shows these days are crap: blank CDs, PC software, the occasional porn DVD bin, and maybe 1 or 2 vendors with Biostar cheapo mobos and $25 cases with 220w junk power supplies and lucite water-filled midtower side panel replacements with fake fish in them.
I honestly don't care about pretty moving maps. I like street-address-level route plotting. I'd prefer it on a linux-based PDA. I'd even pay what a comparable Win32 program would cost, or run one under wine if it were compatible with a card-based GPS receiver.
The GPS in my car just does voices, text and arrows, and I'm just ducky with that. However, without routing, IMHO, GPS is useless on the road.
IIRC Navte(ch|q) uses an open format (SDAL) for its routing database, you have to buy the CD/DVDs. Does anything out there work with _any_ routing data to do routes for Linux?
... nearly ruined Audi in the 80s, thanks to a few issues with the SWI*..
Turns out folks were ham-footin' the small brake pedal and hittin' the gas at the same time with their big fat American feet. That's why automatic cars have shift locks now. OTOH, you will never hear the FedGov call a voter/taxpayer what they really need to be called: a dumbass. P. J. O'Rourke wrote up a really good commentary on this in one of his books that I can't recall right now, but it was pretty spot-on and funny, as most of his stuff is.
Unfortunately IIRC you have to be user root to chroot, and theres lots of other dependencies on mozilla.. like/dev/null, xdpyinfo, awk, etc. But if you keep plugging away it should work.

You meant the outer cylinders, right? They have a higher transfer rate.
They have a higher sequential rate, but lower random access rate. Think i/o ops/sec rather than MB/s.

But OSX has Aqua theme.
So does KDE. In fact, it's better, since you can easily change the jelly color, and the tint of the metal (if you prefer metal).
In Baghira, I have 14k-gold tint metal and red jelly, so I have a nice 70's pimp LED watch motif.
Also, the konqueror shortcut thing is teh sh33t. I've added a few to my own install...

I'd rather have a triple screen 'cave' for FPS gaming, as long as the game could support the resolution (say, 5120x1200 ;).

Of course i'd have to be able to drive them together in Xinerama, and be able to support 2x accelerated cards, like 2xPCIe without SLI..
But still.
