In an article in The Register, Intel's director of IT talks about making savings by deploying Linux across their enterprise, although the amount (~$200K) doesn't sound particularly massive in the scheme of things.
He says the savings "have come from price/performance advantages, reduced software licensing and maintenance costs".
I've found that an AMD CPU will give you warning signs like lockups, kernel panics, and other goofy things when you loose a fan. My mainboard will shut down 5 sec after the post if the CPU fan is not spinning fast enough! Since they are good up to ~100C, using a motherboard monitor prog will go a long way to making sure it runs safely and shuts down before it gets into deep weeds. A copper heat sink goes a long way to passive heat removal as well in an emgerency situation.
IIRC, the main problem with the AMD processors was that they would burn out in around 3 seconds in the (unlikely I know) event that the heatsink fell off. Another point was that the plastic tabs which the heatsink was clipped to, weren't particular strong, so it perhaps wasn't as unlikely as one might think.
Not only does the server run under Linux, the prototype phones themselves run a full 2.2 Linux kernel on a Strongarm. Obviously if the phones were to go into production they would have to be cut down a bit.
I found the SonicWall to be very expensive compared to products from people like Netgear. Also it has a very cheap feeling case compared to the nice rugged Netgear ones. And I managed to crash it straight after initially setting it up and had to reflash it.
I do the same with my Nokia 8210 and Psion Revo Plus. The Revo also synchroinises with Outlook on my desktop so I guess there is scope there for synching all 3, but I haven't tried it.
The Revo also worked with an Ericsson T10 with an IR adapter.
As many people have already pointed out, it's not running Linux but Cynus' eCos. The Register has a good article about it, and speculates on how it will compete against other products already in the marketplace (e.g. Symbian).
That is definitely caused by MSFT's incompetence. One of the first rules of security is not to run any unnecessary services. I installed Win2K on my home machine and immediately discovered that it was running IIS, including FTP, W3SVC and SMTP.
Totally unlike RedHat which doesn't automatically install and run sendmail, apache, etc?
It seems very harsh to blame Microsoft for the slow adoption of IPv6. There's been an IPv6 stack available for Windows for ages. I would guess it's more the ISPs who are holding back on upgrading expensive equipment.
So they're saying that if you can predict the port number that will be assigned to a session, you can hijack it?
No, that's not what they're saying. Every TCP packet has a sequence number (ISN). The initial value for a given connection is chosen at random. Subsequent values are then obtained by adding on the number of bytes sent so far.
A 2x die size saving results in 5% drop in performance because we're in the realm of diminishing returns. Chip designers are trying to squeeze the max. performance out of chips, and have to resort to cleverer and cleverer ideas and bigger and bigger areas of silicon.
The poster wasn't comparing RISC and CISC. He was comparing instruction throughput of one generation of chips to the previous and noting that P4 was going backwards, not forwards.
But car components do not have particularly complicated interfaces; they fit together in 3 dimensions. Computer component interfaces are far more complex because of the temporal relationships.

According to the log it's for real. Wil has even admitted to it.

Wil Wheaton recently did a very funny short interview over at BBSpot.

Yeah, but that doesn't look like a buffer overflow in VB, but in Windows and so exploitable from any language that can call Windows APIs.
john
As I remember, the 63K "bugs" also included requests for enhancements, etc, too.

But no system can be made absolutely secure. Even the best maintained sites have been cracked.

The kernel itself doesn't contain any drivers nor any filesystems. They are all loaded at runtime.
Yeah, but they still run in kernel space rather than user space, so it's not a microkernel, but not quite monolithic either...

Which is an ironic comment given that i18n stands for internationalisation.

You can go and sort it out. :)

My W2K box at work has been up for over a fortnight. I use it heavily every day (software development, wp, web, e-mail). Cheers, john
