technobabbler » Blog Archive » drive a webcam with python
by karlcow
I bought a USB webcam off of eBay quite some time ago, and I decided to connect it to my telescope with a little bit of hardware hackery. I'll have to see about posting a writeup on how I did that at a later time. Anyway, when I installed my camera software, I quickly found how horrible the program was. It gave a tiny preview of what the camera saw, and had no way of capturing images or video without waaaay too many clicks of the mouse. That's when I decided to write my own in Python.
Building Support for Use-Based Design into Hardware Products
by karlcow
Increasingly, hardware products (especially consumer electronics) include computers, sensors, and connections to the Internet. These capabilities enable changes in what products “know,” how they are used, and how we develop them. They are becoming more like websites. This simple fact became apparent to me during my work at Dash Navigation as their design director.
Dell PowerEdge T310 Server Overview
by danijelzi
(via)
The Dell PowerEdge T310 is the company’s latest single-socket tower server.
Along with a single Intel Xeon 3400 Series quad-core CPU, the Intel 3420 chipset-based PowerEdge T310 includes up to 32GB of registered (RDIMM) or up to 8GB of unregistered (UDIMM) DDR3 memory, and up to four 3.5″ cabled or hot-swap SAS or SATA hard drives for a maximum of 4TB of internal storage.
The system has an onboard SATA controller without RAID functionality, but there’s a variety of additional storage controllers supporting up to RAID 10. The basic network adapter is an embedded dual Gigabit NIC, which can be accompanied by various single-, dual-, or quad- port Gigabit cards. For server management, customers can use the baseboard management controller and one of optional iDRAC6 controllers.
Dell’s T310 features the Matrox G200eW GPU, a DVD drive, optional PowerVault tape or hard drives for backups, and five PCIe Gen. 2 slots: two x8 slots (one with x16 connector), a x4 slot (with x8 connector), and two x1 slots.
Power supply options include a redundant 400W and a non-redundant 375W unit.
On the front of the chassis, the 20.5 inches deep tower server has an optional LCD screen for system monitoring.
The new PowerEdge comes without operating system or with one of Windows Server, Windows Essential Business Server, and Small Business Server editions, as well as with optional Novell SUSE Linux Enterprise Server or Red Hat Enterprise Linux.
The starting price for the Dell PowerEdge T310 is $949, with the 3Yr Basic Hardware Warranty included.
The server can be purchased at dell.com.

Hardware interrupt - IDE ATA and ATAPI disks use PIO mode after multiple time-out or CRC errors occur * In Windows XP and Windows Server 2003, this time-out value is always 10 seconds.
by decembre
* An alternate, less-aggressive policy is implemented to reduce the transfer mode (from faster to slower DMA modes, and then eventually to PIO mode) on time-out and CRC errors. The existing behavior is that the IDE/ATAPI Port driver (Atapi.sys) reduces the transfer mode after any 6 cumulative time-out or CRC errors. When the new policy is implemented by this fix, Atapi.sys reduces the transfer mode only after 6 consecutive time-out or CRC errors. This new policy is implemented only if the registry value that is described later in this article is present. To implement the alternate behavior (reducing the transfer mode after six consecutive time-out or CRC errors instead of after six cumulative time-out or CRC errors), you must modify the registry as described below after you apply the hotfix..

Uma mensagem recente na debian-devel-announce descreve detalhadamente os problemas enfrentados pelo sistema de boot atual do Debian e o que está sendo feito para consertá-los.
Segundo a nota, as mudanças no boot do Linux ao longo dos anos recentes tornaram-no mais e mais orientado a eventos, com mudanças que deram fim ao bloqueio enquanto o sistema procurava por discos e outros componentes de hardware, e estas alterações foram tornando mais frágil o anteriormente confiável velho sistema de boot do Debian.
As mudanças propostas incluem mudar o sequenciamento dos scripts de inicialização (para considerar as dependências) e migrar para o Upstart, desenvolvido originalmente para o Ubuntu e já adotado por outras distribuições como o Fedora e o Maemo. A migração já deve ocorrer durante o desenvolvimento da versão Squeeze. (via lwn.net)

Unknown Device Identifier 6.01
by fxbis
& 2 others
Unknown Device Identifier enables you to identify the yellow question mark labeled Unknown Devices in Device Manager. And reports you a detailed summary for the manufacturer name, OEM name, device type, device model and even the exact name of the unknown devices. With the collected information, you might contact your hardware manufacturer for support or search the Internet for the corresponding driver with a simple click. With this utility, you might immediately convert your unidentified unknown devices into identified known devices and find proper driver on the Internet and contact the hardware device manufacturer or vender. Known devices recognized by Microsoft Windows will also be analyzed independent of the operating system.

Posté le 11-09-2008 à 14:41:07 Edit du 7/02: Le firmware seagate SD1A semble résoudre tous les pbs de mode busy pour les disques pas encore touchés. Plusieurs séries de Seagate 7200.11 sont victimes du même problème, du jour au lendemain les hdd deviennent invisibles, non reconnus par les carte mères etc. alors qu'ils tournent encore, que les parties mécaniques ne semblent pas atteintes. Le disque reste en "mode busy". Voici les méthodes de récupération ayant fait leurs preuves chez plusieurs personnes: Jisse6 http://forum.hardware.fr/forum2.ph [...] 0#t6845124
