Wire Transfers Bad, Credit Cards Good

Wednesday, December 31st, 2008

ThiefWhen buying over the internet, if the seller asks you to pay via wire transfer, then it’s most likely a scam. This is because wire transfers cannot be canceled or disputed. The best practice is to use a credit card for internet purchases.

The Core Wars

Monday, December 29th, 2008

CPUIt seems like the new thing in computer hardware is to get the most cores. If two is better than one, then why not four, or eight? But the truth of the matter is that processing power doesn’t necessarily increase at the same rate as the number of cores. One of the major problems is the “memory wall”, where the cores still share common memory and you’ll run into a situation where one core is waiting for another to finish using the memory bus. The linked article mentions the case where, for certain types of problems, a 16-core CPU has about the same processing power as a dual-core CPU. Yes, you read that right. The recommended solution is stacking memory on top of the CPU—I’m not sure what exactly that means, but I imagine we’ll be hearing more about it in the coming years.

The linked article has a handy flowchart that you can send to friends or family members, telling them what they need to do.

The Star of Bethlehem

Wednesday, December 24th, 2008

SpaceThe linked article covers several theories on the astronomical basis of the Star of Bethlehem. The conjunction of Venus and Jupiter was just recently announced and is my favorite, especially since the period between the major conjunctions was 9 months.

What Internet Backbone?

Monday, December 15th, 2008

InternetThe internet was designed to be decentralized, error-tolerant, and highly variable in how it could route packets from one computer to another. According to Wikipedia, the “internet backbone” is “made up of a large collection of interconnected commercial, government, academic and other high-capacity data routes and core routers that carry data across the countries, continents and oceans of the world.” The internet doesn’t have a backbone in the traditional sense; rather, it’s more like a spider web. Many of the connections referenced in the Wikipedia definition are between major service providers who have cooperative agreements (I’ll carry your traffic if you’ll carry mine). The linked article explains what happens when one of those agreements breaks down, and gives insight into just how fragile the internet can be.
