As many of you know cellphones, and other wireless handheld hardware emits RF radiation at low levels. Since I am considering using a cellphone as my primary phone line (as in not paying for a land line), I realised that the use of cellphones in this manner is quite new (within the last 10 years lets say). I can't help but wonder if this will pose a health risk in the long term.
A recent study just published by Popular Science magazine found a "link between microwave radiation emitted by GSM mobile phones (the most common type worldwide) and brain damage in rats". Even "hands free" sets that you can buy for cellphones are believed to worsen the levels of cell phone radiation in the brain. Even the FDA website says that "There is no proof that wireless phones are absolutely safe". Most people ignore these risks because nobody is dying from cell phone use today, but could this cause a health disaster in the future? I am sure many slashdotters are quite attached to their cellphones, what do you think about this risk?
Ok guys I have one CPU question that is yet to be answered. Aside from increase memory access and integer/float width. What could the possible advantage of a 64-bit 3D game have.
I doubt any of the calculation in a modern 3D game would need variables as accurate or as large as 64bits. Thus how could there be any speed increase?
Register size/Bus speed/hypertransport all can be added to current 32bit platforms. The introduction of 64bit instructions as far as I can tell will not offer any benefit to a gamer.
It's not like you can "pair up" instructions now... those instructions that used to be 32bit, when recompiled simply take up 64bits now, right? If your video games don't require hugely accurate numbers... The 64bitness of an instruction set adds nothing!
What am I missing? anything? And don't give me that crap about 64bits means more width for memory transfer. That's bullshit. Your nice little 32bit instructions are taking up that bandwidth already just by the recompile for 64bits.
Not too long ago I was given the "Kiosk project" at my work environment.
As far as your concerned these are winXP machines. We have 4 on the same lan. I was thinking of having a wake-on-lan system that would force a kiosk to send a "wake-on-lan" request to a neibooring kiosk if it was offline.
But that doesn't really help me if the kiosk is crashed and online. Is there a similar "reset-on-lan" feature out there?
I just came back from a nice little trip around mexico (Mexico city, Oaxaca, Puerto Escondido, etc..) One thing I noticed was how cheap service is their.
Christ 1$ U.S. to have a beer served to me on the beach. 6$ U.S. for a fancy 4 course meal!
The list goes on. Imagine making US dollars, but doing it all remotely from a hut on the mexican pacific? (sure you'll have to bend a few laws.. but that's what mexico is for:) ).
Sounds to me like you have nothing holding you here anyways. No GF etc..
I have to say after reading up on the "Rocks" cluster OS software they were using, aside from extravigant benchmarks, and bragging rights most of these multi-node cluster "supercomputers" are fluff when it comes to the average users's applications.
I buy a dual CPU or A Quad CPU machine for example because I know when I run a multithreaded app in XP or 2k or linux it'll spread out the load on all the cpus.
Just about all of these cluster programs are a complete pain in the ass, and either required specially programmed software, or some other terribly annoying method.
Is there any cluster software out there that'll behave (although obviously not performance wise) similar to having a multi cpu system? Where I don't have to jump through hoops.
In case you are interested, but don't want to hunt around. Here are the list of changes in 7.4 devel branch:
Server Operation
Allow IPv6 server connections (Nigel Kukard, Johan Jordaan, Bruce, Tom, Kurt
Roeckx, Andrew Dunstan) Fix SSL to handle errors cleanly (Nathan Mueller) SSL protocol security and performance improvements (Sean Chittenden) Print lock information when a deadlock is detected (Tom) Update/tmp socket mod. times regularly to avoid their removal (Tom) Enable PAM for MAC OS X (Aaron Hillegass) Make btree indexes fully WAL-safe (Tom) Allow btree index compaction and empty page reuse (Tom) Fix inconsistent index lookups during split of first root page (Tom) Improve free space map allocation logic (Tom) Preserve free space information between postmaster restarts (Tom) Set proper schema permissions in initdb (Peter) Add start time to pg_stat_activity (Neil) New code to detect corrupt disk pages; erase with zero_damaged_pages (Tom) New client/server protocol: faster, no username length limit, allow

Rename server parameter server_min_messages to log_min_messages (Bruce) Rename show_*_stats to log_*_stats (Bruce) Rename show_source_port to log_source_port (Bruce) Rename hostname_lookup to log_hostname (Bruce) Add checkpoint_warning to warn of excessive checkpointing (Bruce) New read-only server parameters for localization (Tom) Change debug server log messages to output as DEBUG rather than LOG (Bruce) Prevent server log variables from being turned off by non-super users (Bruce) log_min_messages/client_min_messages now controls debug_* output (Bruce) Add Rendezvous server support (Chris Campbell) Add ability to print only slow statements using log_min_duration_statement
(Christopher) Allow pg_hba.conf to accept netmasks in CIDR format (Andrew Dunstan) New is_superuser read-only variable (Tom) New server-side parameter log_error_verbosity to control error detail (Tom) postgres --help-config now dumps server config variables (Aizaz Ahmed) Make default shared_buffers 1000 and max_connections 100, if possible (Tom) Add new columns in pg_settings: context, type, source , min_val, max_val (Joe) New pg_hba.conf 'hostnossl' to
Ok "the masses" to me means people who aren't overly computer literate, but are interested in transporting data from home to work or wherever.
As for backup, usually that is handled automatically at work. At home maybe all they would need to do is backup documents and email.. which will fit on a cd. And besides, relying on one 120gb HD as a backup makes no sense. If you want incremental backups... it won't last long. And you need removable media to store somewhere else.
As for the "computer saavy" person. Christ.. It'd be much cheaper for me to simply carry around an HD on it's own, open the friggin case and plug it into an IDE channel.
Just so you know, in an unsigned 32bit integer, you can fit around "4 000 000 000". So that problem techincally won't happen for another 50 to 60 years or so after 2038.

But I look waaay sexier next to traditional lighting.

uuuh, I don't get it :)
I formulate a paragraph of a subject of major concern, and this makes me a bot?

Thanks! The second option seems fine. anything to prevent me from physically have to approach and reset a kiosk.
From what I can tell, the only downside is that it'll need its own IP address. (Which we try and conserve at my workplace).

A big downside is you'll have to be in direct contact with Mexicans :)

Linus Torvalds just took a shit!
Let's post it on slashdot!
And afterwards, I'll even teach you how to wipe your ass.

Seriously... karma or not, it needed to be said
Why would this be any more widespread with another mp3 player? or a discman or anything for christ sake?
Seems like every geek with a fashion crisis has to spend money on apple products these days.
Yeah I looked into that a while ago.
It`s as close as it comes to what I`m looking for but not quite.

I'm betting by 2005 my 32bit cpu well become self-aware and upgrade itself.
I always thought most modern ethernet cards were compatible with some generic brands.. like ne2000.
Or do I need to download special drivers, or windows drivers/dlls, etc??
I do some software devel, but I don't even get the meaning of this post :)
TPS reports?!? lol... did you get that from the movie Office Space ?

I don't mean to sound like a complete troll, but why on earth do we give a rats ass about what Philip Greenspun thinks.
After reading through his "website", I can only conclude he's a nobody...
Are we going to start picking are "blog celebrities" with particular reasoning?
He comes a across as nothing more than CHEAP with blindingly genious statements such as "java is the suv of programming"

But it was because I had to wipe my cats ass.
Nobody can argue with that.
