New computer

Friday, October 24th, 2008

I was shopping for a new computer at Alienware this morning. Some of their upgrade prices, especially for RAM, looked fishy. You can get what appears to be the same items from Newegg for less than what Alienware charges as the upgrade price. The upgrade price means additional cost to what you are already paying for the base component. This seemed especially true for the 2 GB low latency patriot memory upgrade. Alienware wanted an additional $600 but I can apparently buy this from NewEgg for $240.
The memory from NewEgg

If the items are not equivalent I’ll correct this but they definitely need to work on justifying why I should pay $600 for 2 GB of memory.

I found Cyberpowerpc.com which gives you a great deal of freedom in what parts to pick. I built a computer that would cost about twice as much from Alienware. The only problem is that it’s very hard to know what parts to pick given the wide range of options, some of which are incompatible. The website form isn’t that good either, often resetting your choices if you go back and forth between pages.

I basically ordered the top of the line AMD, with dual top of the line video cards.

Memory heap allocator faster than new/delete

Sunday, October 19th, 2008

Here’s a class that given a predefined area of memory, allows you to allocate and deallocate areas of that memory. In other words, a custom memory manager.

Only partially done yet, but it’s already 25% or so faster than malloc and free
Header
CPP

Full alloc, then dealloc
Heap = 1304 us
malloc = 878256 us

Fragmentation
Heap = 3525 us
malloc = 4462 us

Most of the speedup comes from linked lists of buckets. There are 7 buckets, from 32 bytes to 2048 bytes, incrementing in powers of two. 20% of the given memory is dedicated to buckets. If an allocation is requested and a bucket is available, the allocation goes to that bucket instead. Because buckets are contiguous and reserved, those allocations cannot cause fragmentation.

The alignment boundary is 32 bytes, so all allocations returned to the user are aligned, and the average memory wasted per allocation is 32 bytes, excluding buckets.

The speeds shown are with a critical section lock. This is not necessary, and for single threads it would be even faster.

Ron Paul on the bailout

I’m moving my money out of US dollars. Foreign currency CDs are the best. Currently Canada has the most sound banking system, so is the least likely to suffer a depression when the dollar crashes.

By IQ scores, Palin is dumber than 85% of the population

Friday, October 10th, 2008

According to this site, McCain has a 15% chance of dying of old age while in office.
http://www.marshfieldnewsherald.com/apps/pbcs.dll/article?AID=/20081003/MNH06/810030395

The chance of Palin becoming president is higher than that, since you usually are unable to work for some time before dying.

So with that news, according to the public records on this site:
http://clapboard.org/temp/SarahPalinReport.pdf

Palin’s IQ is only 83, over one standard deviation, which means she’s dumber than roughly 85% of the population:
http://en.wikipedia.org/wiki/Standard_deviation

Most of my views lie with Republicans, but the last thing we need is another idiot in office. As much as I can’t stand socialism, I’m going to vote for Obama just so McCain doesn’t become president.
