Over the weekend, I ended up on San Francisco’s ritzy Fillmore Street. I stopped by to say hello to my dry cleaner and then to Ed Nahigian, a gentleman who has been taking care of my footwear since I moved to San Francisco. As with everything else, the conversation turned to the market meltdown and the pending auto-industry bailout. From our conversation emerged some common sense advice that’s applicable to business of all shapes and ...

ซีพียูที่ร้อนแรงที่สุดในปีนี้คงต้องยกให้ Intel Atom ที่เปิดตลาด netbook อย่างรุนแรง แต่ถ้าคนอยู่ในวงการวิจัยหรือกระทั่งคนที่ต้องดูแลเซิร์ฟเวอร์จำนวนมากๆ แล้วคงแอบหวังที่จะเอา Atom ไปใช้ในเซิร์ฟเวอร์กันอยู่ เพราะการปล่อยความร้อนที่ตำเอาเสียเหลือเกิน และเจ้าแรกที่เปิดตัวเซิร์ฟเวอร์รุ่นต่อไปด้วยแนวคิดนี้จริงๆ ก็คือ SGI ที่เปิดตัวเซิร์ฟเวอร์ขนาด 3U ที่อัดซีพียู Atom ไว้ถึง 180 ตัว ชื่อรหัสของโครงการนี้คือ Project Molecule (เอาอะตอมมาเรียงกันต้องเป็นโมเลกุลสิ) โดยทำเมนบอร์ดแบบพิเศษที่มีขนาดเล็กมาก แล้วใส่กล่องเป็นบล็อกเรียงกันไป ชิปที่ใช้คือ Atom N330 ที่มีสองคอร์ในตัว ทาง SGI ระบุว่าแต่ละบอร์ดจะรองรับหน่วยความจำได้ 2 กิกะไบต์ ทำให้หนึ่งเครื่องจะมีคอร์ x86 อยู่ถึง 360 ชุดและหน่วยความจำสูงสุด 360 กิกะไบต์ โดยที่กินไฟน้อยกว่า 2 กิโลวัตต์ทั้งตู้ ก้าวต่อไปสำหรับโครงการนี้คือ การขายตู้ทั้งตู้ที่มี Atom อัดแน่นมากกว่า 10,000 คอร์ในตู้เดียว โดยจะมีระบบหล่อเย็นแบบของเหลวเข้ามาช่วยด้วย ปรกติแล้วระบบกริดขนาดเล็กๆ เช่นนี้ก็มักจะใช้ชิปขนาดเล็กๆ เพื่อความคุ้มค่าในแง่ของพลังงานกันอยู่แล้ว แต่ Atom นั้นจะเป็นครั้งแรกที่เราได้เห็นชุดคำสั่ง x86 บนเครื่องแบบนี้ ที่มา - Tech-On

I went to the IDC HPC Breakfast briefing yesterday morning because they are usually pretty interesting. This one felt mostly like a rehash of earlier material and was somewhat disappointing as a result. I did hear a few things I thought were worth passing on and here they are. I made the above graph based on a table that was flashed quickly on the screen during the briefing. If N was specified, I didn't catch ...

If you are running Adsense Pay-Per-Click ads on your site, it is usually adviseable to blend the colors in with the rest of your site so that your ads don’t distract, detract from your design, or scream “I’m an Ad!” A general rule which usually works for me is to keep the background color of my [...]

The latest Top500 list was unveiled on Friday. For those who haven’t read the release, whoa nelly! The list has always been a highly debated and contested flexing of one’s supercomputing might. This list was no dissapointment. The biggest story of this year was the backyard brawl between ORNL’s Cray XT5 system, Jagaur, and the reining champ, RoadRunner at LANL. Fighters, to your corners! It was widely publicized that Jaguar had a distinct chance to ...

Fascinating excerpt from Malcolm Gladwell’s soon-to-be-released Outliers: The Story of Success: This idea — that excellence at a complex task requires a critical, minimum level of practice — surfaces again and again in studies of expertise. In fact, researchers have settled on what they believe is a magic number for true expertise: 10,000 hours. (Thanks to Tom Davis.) ★

Genius takes 10,000 hours, or about ten years of 3 hours a day, to blossom into world class success says this article. So, if you aren't a world class expert at anything today, what do you want to spend 10,000 hours refining? Or what are you already putting your hours into?

Reshared from Mike.I like the idea of this... expertise in a job would take 4.8 years. That probably explains the 5-year-itch, etc. But it doesn't really explain the burnout: why would you spend 10,000 hours at something to be an "expert" and not leverage your expertise? I suppose the best explanation is that human beings are flawed (or at least irrational).
