This is of course not the first liquid that does not cause harm to electronics, and can be used for total immersion water cooling.
Fluorinert (3m) has been around for a while.
One version of it is(was) also used for liquid breething deep diving (same as used on "The Abyss").
Any anonymization Tivo claims to perform on data uploaded by an individual's Tivo unit is rendered utterly and totally worthless by the medium by which the data is transferred - a landline.
That only applies to TiVo's connected to a phone line. All the new ones (series 2, and hacked series 1's) can connect through a network connection, and the IP is usually part of an ISP's IP pool. So the only thing they'll get is the geographic location, not the specific user.
HP has an replacement pad kit for this printer (same thing happened to me) It should be free (if they still have it) and installs in 2 minutes or less.
The rubber pad in the bottom of the paper tray is dry and doesn't hold tha paper in anymore.
I have a HP 6L. The feeder stopped working correctly about 1.5 years ago (after being in use for 3) It is actually the rubber pad on the bottom of the paper tray that holds the paper in place that wears out. I got the HP repair kit (free) and it worked like a charm. Haven't had a single problem afterwards.
GPL'd source guarantees that nothing lives in your kernel that you cannot examine as much as you like for backdoors. Yet this examination has to be done somebody else, by larger group of people who have great amount of knowledge and experience on these matters. It is simply not "possible" to this guy/girl to examine the kernel. Besides it is not not a easy task look for backdoors etc. Does anybody know that this kind of examination has been taken place by independent group?
So you mean I can't just do: cd/usr/src/linux grep -R backdoor * :)
systems used static ram which needs something like 18 transistors per bit and consummed orders of magnitude more power and board area
A normal SRAM bit takes 6 tansistors (FET's), while DRAM takes 2 (one of which is used as a capacitor and stores the bit)
if static memeory were still in use, a 1 gig memory card would be about ten times larger than todays dynamic memory and consume about 1 mega watt of power!!!! in static memeory current is flowing the whole time. in dynamic memory current only flows when the bit swithces state, the rest of the time it just stores charge. storing charge does not disspate any power. thus the future of computing hinged on dynamic memory.
Current doesn't flow all the time in SRAM... (At least not in CMOS based SRAM, might in TTL based) Each bit consists of 6 transistors aranged as a flip-flop. This does not consume _ANY_ power (except for leakage current, which is very low) except when it is changing state. DRAM on the other hand has to be continually refreshed, and thus consume quite a bit more power.
Only reason that DRAM is user more is because it takes a third of the space of SRAM. Anything that needs ultra-fast RAM uses SRAM (Some videocards and all L1 & L2 CPU caches uses SRAM)
Since the method relies on knowing the default TTL, (128 for windows), just set the default TTL to something higher...
In W2K: HKEY_LOCAL_MACHINE\System\CurrentControlSet\ Servic es\Tcpip\Parameters\DefaultTTL (DWORD)
Just set to 129 if you have a NAT between your PC and the modem.
This way all the packets seem to come directly from a Windows box, and you don't have the (potential) sideeffects of getting the NAT to change the TTL.
"All the information from the 2000 census is available for free from the United States government," Anderson said. "No one is out in front of their mailbox with a shotgun to prevent direct marketers from distributing targeted print advertising. Yet with television, there is a greater level of concern."
Well duh..... Mail spam can be ignored (ie: tossed directly in the garbage), while you can't skip these (as easily). If they are going to equate themselves with mailed advertisement, htey should also give us the means to ignore them. A built in comercial skip would be nice.
Or maybe just hakt the box to ignore these channel change commands.
Not sure about other brands but some of the Dell Inspiron range have removable video cards. The LCD panel plugs directly into a small daughterboard which holds the video chipset.
So does the HP Pavillion series (opened one up today to fix something)
A while ago I remember somebody making a computer in a briefcase. This could do nicely as a case for a selfmade portable.
Use a lightwight motherboard or a PC-104 based stack. PC-104 is more likely to have the nice addons as networking (wired and wireless) and usually are easier to run of a single voltage.
They are also more expensive....
Buy a cheap 15in LCD momitor, and hack it to run of 12 volts instead of AC.
Use a 12V sealed Lead Acid or Lead Calcium battery (the type usually used in UPS) This will add some weight, but will give you a long battery life and lead acid batteries are easy to charge, and usually lasts a looooong time with proper care.
Add you favorite keyboard (keep it in its own casing so you can detach it ) and a CD-ROM drive and you have your ovn portable (not quite a laptop) that guarranteed will give you some (unwanted) attention at security checkpoints at airports:) -snap- (sound of rubber gloves)
Seriousely though... A portable like this could be made for $500-$1000 depending on the hardware used.

It is the size of a DIMM (Actually it IS a DIMM)
It features 2 serial ports (rs232, but it is very easy to make a 232 to rs422 converter, I have schematics laying around somewhere), and also a 10BaseT network interface, plus 1-Wire Net, CAN, General purpose IO, and expansion bus.
It is a neat embedded architecture.
It is not running Linux, but has an embedded Java VM --

Could not find it in 2.6.4, but a patch to kernel/kthread.c to 2.6.1-rc1-bk6 shows these lines:

Which is from the Holy Grail

Me and three friends split $1000 to buy a 2x Sony SCSI burner in February 96. This was in Norway so the prices were probably higher (8000 NKR)
Media was $10 per disk.... Coasters really sucked....
Haven't gotten that one yet... Could explain it I guess...
When I read 'Librarian', I go a mental picture of an orangutan sitting at a desk , eating bananas and going 'Ook?'
You mean there really was a "dread pirate Roberts"?
Which of course is a reference to the Princess Bride...
So you mean I can't just do:
cd
grep -R backdoor *

What happens if the spammer just uses the same address in the To: field and in the Reply To/From: field?
A challenge will then be sendt to you, and will be accepted (since it comes from yourself....)

Using @Home (Midcontinent) in Rapid City, SD, I get 10Mbps down and 128kbps up. Routinely get 400 - 450 KBps download speeds from select sites.
Actually, Norway have had Digital test transmissions the last couple of years, and are planning to switch to digital only in a year or so.
