Sun Microsystems Inc., looking to turn an IBM Corp. marketing gaff into a public relations coup for itself, announced Friday that it will help the City of San Francisco clean up the sidewalks Big Blue spray painted as part of its Linux eServer advertising campaign. Big Blue said the sidewalk advertisements were supposed to be done in biodegradable chalk, but, at least in San Francisco and Chicago, black spray paint was used instead.
That last paper is Richard Gabriel's follow-up to his original Is Worse Better?/i> paper. A cool quote from the "Back to the Future" paper:
Last year, this Common Lisp code was selected by a NASA panel for NASA's software of the year award. Despite this and despite the fact that the software works well in space, one of the high officials at NASA blocked the award and declared that it would not be given unless the system were re-coded in C, in which language it would be obviously better because... um, becase... ?
Many "modern" functional languages, like ML and Haskell, have strong-yet-polymorphic typing and all of the functional abilities of Lisp. Of course, these languages suffer from a derth of libraries, too.
Of course, this is a COM interface for Haskell called Haskell Direct, allowing your Haskell program to call COM and ActiveX controls. This work was done by someone in Microsoft Research and wrote a paper about it humorously titled "Calling Hell From Heaven And Heaven From Hell.";-)
Does Linux's fsync() actually lie optimistically to the calling application that the user's data has been fsync'd to disk?? Do you have any links to information about this? scary stuff!
I don't know much about IRIX. If SGI is up to IRIX 6.5.11, does that mean they have not shipped even a +0.1 minor release in 11 quarters? yikes. That's about when Microsoft released Windows NT4.
Is SGI still actively developing IRIX? Do you know if SGI has plans for any more IRIX releases? (seeing how your username is irix and all...;-)

I have enabled Explicit Congestion Notification on zeus.kernel.org, the
machine which contains ftp.kernel.org and filehub.kernel.org. This means
that some sites which are behind broken firewalls may have trouble
accessing it. If you are a mirror site, I would appreciate it if you
took the time and verified that you can still access filehub.kernel.org.
Jeff Garzik has a very good page listing ways to fix your firewall to
deal with these kinds of problems. If someone reports problems with ECN,
I suggest pointing them to it:

In particular Cisco have production-level fixes out for all their
affected products.

The article said they have two hard disks per server, some times four. So that puts the order to Maxtor somewhere between 8,000 and 16,000 hard disks.
Many of Google's storage devices are outfitted with 80GB hard drives from Maxtor. They have a single controller per hard drive and two hard drives per PC. In some cases, the company uses PCs that are twice as big, with four controllers, four hard drives, two processors and twice the RAM of the smaller units.
Synopsis Turn your technical problems over to the mystical powers of the psychic pigs, and all will be revealed!
Background Late one night, it occurred to filmmaker Mark Clarkson that if he had access to a psychic, he wouldn't need love advice - he'd need to know how to get Netscape Mail to remember his password.
In his previous career as a software analyst for the Boeing Company, Clarkson was often getting in trouble for the cartoons that he would sketch on the whiteboard during long program compiles.
Clarkson is a regular contributor to several computer magazines, and a Contributing Editor at Desktop Engineering Magazine.
Fact This animation took about two weeks to complete.
I wonder what kind of information Google has about the deficiencies of the Linux TCP/IP stack? with 8,000 servers they could have some input as to how the lack of mult-threading has affects performance on a major site.
Why do you think Google needs 8000 Linux servers? Linux can only run one or maybe two socket connections per server.
"Google downloads Red Hat for free, taking advantage of the company's open source distribution. And Linux's open source nature allowed Google to make extensive modifications to the OS to meet its own needs, for remote management, security and to boost performance."
I'm sure Red Hat is upset that they are missing out on the sale of 8000+ Linux licenses!!:-) Maybe they should block downloads from the *.google.com domain.

Did you read the story, you know the words at the top of the page? This story is about Samba using TrustedBSD's ACLs. Linus' Linux doesn't even support ACLs without flaky, third-party patches. The Extended Attributes and Access Control Lists for Linux FAQ says:
Q10 When will Posix ACLs be part of the kernel?
There are multiple steps to getting ACLs into the kernel. The first step, which we are heavily debating on the mailing lists right now, is how to design the system call interface for extended attributes and ACLs. The next step will be to include the extended attribute code into the kernel, or create even better extended attribute code for that purpose. Then, on top of that, we can include ACLs for the ext2 and ext3 filesystems. Other filesystems such as XFS be able to support ACLs directly, without needing extended attributes.
but in MySQL you can emulate most, if not all, of those features in your Perl code.. and with far less code than the dangerous C code Oracle includes in their database kernel. For example, the MySQL documentation specifically says:
MySQL, in almost all cases, allows you to solve for potential problems by including simple checks before updates and by running simple scripts that check the databases for inconsistencies and automatically repair or warn if such occurs. Note that just by using the MySQL log or even adding one extra log, one can normally fix tables perfectly with no data integrity loss.
Not even transactions can prevent all loss if the server goes down. In such cases even a transactional system can lose data. The difference between different systems lies in just how small the time-lap is where they could lose data. No system is 100% secure, only ``secure enough.'' Even Oracle, reputed to be the safest of transactional databases, is reported to sometimes lose data in such situations.
Smart companies save money by deploying MySQL instead of Oracle. They can invest that money in smart Linux developers and the NASDAQ. With a powerful return for their money, the developers can run simple scripts to detect database inconsistencies as soon as possible. The developers can immediately load the backup tapes, losing some potential sales but maintaining perfect data integrity. Neither Oracle nor SQL Server allow you to run these simple scripts to automatically repair database inconsistencies. Is your data truly safe in a "black box" like Oracle or SQL Server?

The Psychic Pigs doing tech support is both funny and relevant to the story topic of "Microsoft Tech Support vs Psychic Friends".
The article said they have two hard disks per server, some times four. So that puts the order to Maxtor somewhere between 8,000 and 16,000 hard disks.
Many of Google's storage devices are outfitted with 80GB hard drives from Maxtor. They have a single controller per hard drive and two hard drives per PC. In some cases, the company uses PCs that are twice as big, with four controllers, four hard drives, two processors and twice the RAM of the smaller units.
Check out Atom Films's Psychic Pigs Tech Support . It's a Flash animation and pretty darn funyy.
Synopsis
Turn your technical problems over to the mystical powers of the psychic pigs, and all will be revealed!
Background
Late one night, it occurred to filmmaker Mark Clarkson that if he had access to a psychic, he wouldn't need love advice - he'd need to know how to get Netscape Mail to remember his password.
In his previous career as a software analyst for the Boeing Company, Clarkson was often getting in trouble for the cartoons that he would sketch on the whiteboard during long program compiles.

Why do you think Google needs 8000 Linux servers? Linux can only run one or maybe two socket connections per server.
"That's not to say that the index takes up a petabyte. We have several hundred copies of the index," Google's Lindsay Felton said.
"Google downloads Red Hat for free, taking advantage of the company's open source distribution. And Linux's open source nature allowed Google to make extensive modifications to the OS to meet its own needs, for remote management, security and to boost performance."
I'm sure Red Hat is upset that they are missing out on the sale of 8000+ Linux licenses!!
