  1. CCIE on What's the Point of IT Certifications? · · Score: 1

    While most of the IT certifications do not have any real value, there are still some that do. Cisco Certified Internetwork Expert is a perfect example. You have absolutely no chance of becoming a CCIE unless you're a real networking heavyweight. Besides, in order to maintain the level of the title, every two years all CCIEs are required to pass recertification exams. The paper and the medal (I've heard they don't award medals anymore, but I'm not sure; I did get one in 2000) are quite expensive, but they really are worth every penny invested.

  2. Re:no way on Energiya Pushes For A 6-Person Space Capsule · · Score: 1

    Moscow is BY FAR not the toughest place in Russia ;) There is a place, Oymyakon, where -60C is normal temperature in winter. The town also holds the record of lowest temperature ever measured on the northern hemishpere - -71.2C, and the world record in difference between the lowest and highest temperature (109.2C, they have up to +30 in summer). Make a machine work in Oymyakon and it'll work almost anywhere! :)

    Marko Zec has done an excellent work on further virtualizing FreeBSD kernel: Network stack cloning / virtualization extensions.
    Within a patched kernel, every process, socket and network interface belongs to a unique virtual image. Each virtual image provides entirely independent:

    * set of network interfaces and userland processes;
    * interface addresses and routing tables;
    * TCP, UDP, raw protocol control blocks (PCBs);
    * network traffic counters / statistics;
    * set of net.inet tunable sysctl variables (well, most of them actually);
    * ipfw and dummynet instance;
    * kernel message buffer instance;
    * system load and CPU usage accounting;
    * proportional share CPU scheduling
