Normal Stuff - I, Cringely » Blog Archive » Which domain registrar is best? Which domain registrar is best? I have domains from Network Solutions, GoDaddy, and Register.com, but there are many other registrars — some of which must be better than these. Network Solutions is too expensive and difficult to work with, GoDaddy is annoying and greedy, while Register.com may be great but I don’t have a good comparison. I am thinking of consolidating all my domains with one registrar. Where should I go and why? Why I Dislike EC2 Every now and again I tweet about my dislike for EC2. People always ask why. In reality I think Amazon is doing a great job, especially compared to other cloud providers, which are only falling further behind. Price / Performance I've been hesitant to write about it because it feels like beating a dead horse, but so many people seem surprised by it, what harm can it do? To me, AWS is to performance, what Microsoft was to security (pre Bill Gate's Trustworthy Computing memo). Not only is EC2 slow and expensive, it's getting worse as faster processors and hard drives come to market. We use 3 different unmanaged dedicated providers in 4 different locations. Per-Hour Billing + Provisioning The real EC2 advantage is per-hour billing and instant provisioning. If you need to start and stop instances (say you have an unsteady number of jobs), a hybrid approach is going to be more efficient. Reserved Instances You can't talk about EC2 pricing without people mentioning reserved instances. The Myths

Of course, you know I couldn’t stop with just doing the TCP header: IP Header in Lego(TM) Now why am I wasting all that space on the building plate in each case? TCP/IP in Lego(TM) The use of color here really highlights certain portions of the packet header. Actually I wish I had a couple of more colors available. Lego(TM) Byte, Nibble, and Bit So while I tried to use Beige exclusively for size fields, Red for reserved bits, Yellow for checksums, and so on, I ultimately ended up having to use these colors for other fields as well– for example, the yellow sequence number fields in the TCP header. Serious Fun Cute idea, but is there any practical value? TCP Header "Bits" in Lego(TM). Lego(TM) blocks waiting to become TCP header diagram Admit It. Project Tools Final Thoughts Like this:
OpenDUNE.org The Loom The Science Tattoo Emporium continues to thrive, long after I first wondered aloud in August 2007 whether scientists had any cool tattoos of their research hidden under their lab coats. I continue to get photos at a regular rate, and as I post new ones, they continue to get noticed anew by places like Digg and Boing Boing. Initially, I was so stunned by the influx of photos that I posted just about anything that came my way. But as the emporium has grown, I’ve become choosier about which ones I post. So if you are considering sending in your own scientific ink, please read these guidelines: 1. 2. 3. 4.

10 Easy Steps to a Complete Understanding of SQL Too many programmers think SQL is a bit of a beast. It is one of the few declarative languages out there, and as such, behaves in an entirely different way from imperative, object-oriented, or even functional languages (although, some say that SQL is also somewhat functional). I'm writing SQL every day and embracing SQL with my Open Source Software jOOQ. I thus feel compelled to bring the beauty of SQL a bit closer to those of you still struggling with it. readers who have already worked with SQL but never completely understood itreaders who know SQL well but have never really thought about its syntaxreaders who want to teach SQL to others This tutorial will focus on SELECT statements only. 1. Get this into your head first. SELECT first_name, last_name FROM employees WHERE salary > 100000 Easy to understand. What do we learn from this? So if this is so simple, what's the problem? Forget about all that. 2. For simplicity, not all SQL clauses are listed. There are three things to note: 3. 4.
