Linux Kernel 2.6.24

2.6.24 ออกแล้ว

  • CFS improvement .. เดิม context switch ของ CFS ช้ากว่า O(1) sched > 10% .. ตอนนี้ 2.6.24 (เคลมว่า) context switch ใน CFS เร็วกว่า O(1) นิดๆ
  • Fair Group Scheduling .. ตั้ง group ของ processes (ผ่าน /proc – ถ้าจำไม่ผิด) แล้วกำหนดน้ำหนัก CPU scheduling .. ถ้าประกอบกับ CFS มันก็จะประมาณ WFQ สำหรับ CPU scheduling นั่นเอง
  • Tickless สำหรับ x86-64, PPC, UML, ARM, MIPS … ปัญหาที่เคยเกิดกับ VirtualBox (กิน CPU > 10% ตลอดเวลาทั้งที่ไม่ได้รัน VM) หายแล้ว .. อย่างน้อยก็ในเครื่องที่ใช้อยู่
  • Driver ใหม่อีกหลายตัว ทั้ง 802.11 (stack ใหม่) 802.3 (10/100/GbE/10GbE) ALSA (Intel HDA แยก chipset แล้ว) PATA/SATA ฯลฯ

สำหรับคนใช้ macbook (top case แตกๆ) .. อย่าลืม co mactel patch สำหรับ 2.6.24 มา apply patch ด้วยเน้อ

wireless ใช้ ndiswrapper 1.51 ได้ ไม่มีปัญหา

iSight เอา revision 140 มาใช้ + patch อีกนิดหน่อย

OOXML: Your action is required: Contact TISI now!

Dear Kitt Tientanopajai,

You signed the OOXML petition, a movement backed now by more than
70.000 supporters worldwide. Our effort to influence the OOXML (Office
Open XML) standardization process has been an astonishing success so
far. We aim for at least 100.000 signatures in February when the Geneva
Ballot Resolution Meeting (BRM) will convene with the aim to resolve
comments.

Microsoft is trying by all means to get its "standard" adopted without
substantial changes despite of its thousands of officially reported
technical flaws and the pre-existence of ISO 26300:2006 (OpenDocument,
ODF) as the most appropriate international standard for the
representation of office documents.

By next Tuesday Dec 11 2007 delegates from your National Standards Body
TISI who will participate in the BRM have to be announced to
ISO. At least Portugal and Ireland will be represented by Microsoft. In
many other countries, we know that Microsoft gold partners are proposing
themselves as heads of national delegations. Many of them will prevail
if we do not take action.

Will you let Microsoft represent your country at Geneva and decide the
future of OOXML?

You can make a difference and call now TISI at +66-2-2023400-2 and help
us to find out:

a. Who will represent TISI on DIS 29500 at the Ballot
Resolution Meeting in Geneva?
b. When will the decision on delegates be made and if TISI is
aware of the Dec 11 deadline?
c. Does your national delegates for the BRM are independent enough
from Microsoft?
d. Does the responsible Committee of TISI for DIS 29500 work
on resolution proposals for all the 3500 comments tabled or – if at
all – only for the national comments that they submitted?

Please report your findings by replying to this email, we will update
this page with the members of each national delegation:

standard proposal:
