“8″ brings Dead Cat Bounce to PC sales

“Since the Oct. 26 launch of Windows 8, consumer notebook and desktop sales in the U.S. have fallen 21% compared to the same period last year, said Baker. Laptop sales were down even more — 24% year-over-year — while desktop numbers were off considerably less, just 9%.”

see Windows 8 brings zero 'pop' to consumer PC sales | ITworld.

USA gets ~20% of global PC shipments so this means M$’s revenue for the client division could take another big hit. Meanwhile, the rest of the world is buying smart thingies instead of PCs. Wintel is on a downwards trend. It’s about time retailers tried selling GNU/Linux on PCs at reasonable prices. Price matters.

technology Now Sells a GNU/Linux Notebook and It’s Not Small and Cheap

This is the XPS-13 at $1549 in “developer version”. It’s an “Ultrabook”TM with that other OS. I guess it’s a nearly optimal notebook with GNU/Linux although I would prefer Debian GNU/Linux instead of Ubuntu GNU/Linux.

see Dell

I still don’t get why Dell doesn’t sell small cheap computers that run GNU/Linux in USA. They do in India/China. USA certainly does have millions who could afford a small cheap computer but not an Ultrabook.

M$’s Crapware Kills Education Even in Redmond, WA

“The virus is affecting not only high school and middle school students who received a laptop for the first time this year, but also devices at the district office and elementary schools.

That’s 50 schools and more than 25,000 computers. And here’s the ironic thing about it: The Lake Washington School District comprises the cities of Kirkland and Redmond, the latter, of course, being the hometown of Microsoft. Those laptops are all running on PCs with Windows 7.”

via Windows virus causing havoc for school district in Microsoft’s backyard – GeekWire.

There, you have it. The kind of thing I saw in several schools in the North of Canada running that other OS and bogging down IT to unusability. Folks there just did without until I showed them how to migrate to GNU/Linux. The folks in Washington state are hiring five IT guys to try to undo the damage. They won’t succeed. You cannot rewind the clock on everything.

I recommend Debian GNU/Linux, an OS that works for you and not for M$ and it’s malware “partners”.

Oracle Broken MySQL Promises

“Widenius reckons Larry Ellison’s database giant has already broken one promise it made to European regulators as part of its $8.5bn Sun Microsystems purchase when it moved parts of the database into closed source. He also accused Oracle of obfuscating on security and bug fixes, as it has not released all-important test cases for MySQL 5.5.27.”

see Monty on broken MySQL promises: Oracle's going to fork it up • The Register.

If Monty Widenius is correct and the jig is up by 2014, I have about a year to migrate all my stuff to either MariaDB or PostgreSQL. There is a plugin for WordPress which converts transactions to PostgreSQL but that would be slow. It might be easier to migrate my content to another blog… My other biggy is Wikimedia but it knows PostgreSQL so it’s just a matter of re-installing and exporting/importing content.

Oracle promised to do the right thing when it bought MySQL but they have either forgotten or more likely assume the world has forgotten. I have not. I wonder if the EU has.

YES!!! Munich Successfully Migrated 12,000 PCs To GNU/Linux!

Google Translation: “Over 12,000 urban PC workstations to work with the open PC workstation system Linux. The open source office suite communication are the employees of the City of Munich and used to work with LiMux has become routine.
Despite the long duration of the project, each new project milestone was followed by other municipalities and states with interest. And the interest is still undiminished.”

see Munich with over 12,000 PCs Running LiMux | Munich IT Blog: target achieved.

It did take a long time but they did break even by the time of the second avoided “upgrade” of that other OS. They didn’t break anything but dependency on M$. Congratulations, Munich!

Old Phones

“Fifty-five per cent of Brits have an old handset or two lying about the place”

see Half of us have old phones STUFFED in our drawers • The Register.

Chuckle. When I read that headline I thought of the phone in my kitchen, circa 1987 (yep, a dialer). We bought it when the little woman and I bought our first house and it stayed with the old homestead until the renovation this summer. Now it’s in our new house. I always use it if I can because the ear-piece is actually comfortable against my ear unlike those hard flat bricks of smartphones… Yes, rounded corners antedate the iPhone.

Linux Kernel Developers and the Mystery of Slower Mounts

In Linux it is often said that every device is a file. To most of us a file is something just there. The kernel boys and girls actually tweak the bits right down to the hardware to make the magic of a file somewhere becoming accessible to the system, mounting the file.

Last week, one developer found a recent version of Linux mounted files considerably slower than it usually did. He noticed because he mounted a lot of file-systems. When careful timing was done the difference was measured. Indeed mounts were an order of magnitude slower. By repeating the measurements for several versions and finally versions with and without certain patches/changes, the cause was found. Then discussion broke out about how to fix both issues, why the change had been made and how to do it differently.

In the process, coach Linus stepped in having noticed some perspective was missing. He quickly turned the pack around to solve the “real problem” and Linux now is as fast as ever and other problems have disappeared. Yeah team!

“It seems the recent kernel is slower mounting hard disk than older kernels.”

see LKML: Jeff Chua: Recent kernel "mount" slow.

Indeed, GNU/Linux is a cooperative product of the world with everyone contributing what they can and getting the job done. It’s the right way to do IT. In fact, I rarely mount much because I use my system for hours and only mount between session but I think it’s important that someone actually cares if IT slows down for any reason, unlike that other OS when M$ actually benefits when their OS slows down through use and folks buy a new one…

BTW, “here’s the comparison …

0.500s 3.7.0-rc7
0.168s 3.7.0-rc2
0.012s 3.6.0
0.013s 3.7.0-rc7 + synchronize_sched_expedited()
0.350s 3.7.0-rc7 + Oleg’s patch.”

That’s caring.
