Hard Drive Caching in Windows 7

📅 May 6, 2017
After experiencing good success in Linux using RapidDisk and Flashcache (on older kernels) to speed up mechanical hard drive reads, I thought it would be fun to discover if such software existed for Windows.

Is it possible to install hard drive caching software in Windows 7? How would it perform?

I tried four programs, PrimoCache, HDDTurbo, SuperCache 6, and eboostr, and tested reads using CrystalDiskMark. Here are my results.

JavaScript: Get a random number within a range

📅 April 26, 2017
The Math object in JavaScript provides the random() function that returns a floating point value from 0 to up to but not including 1.

What if we want to grab an integer, say, from 1 to 25 inclusive?

We can do this easily by modifying the random result to our liking.

Adventures with the Hyper 212 EVO CPU Cooler

📅 March 21, 2017
Whrrrrrrrr. Buzzzzzzzzzzzzz. Whiiiiiiinnnnnnnne…

Guess what? It’s a noisy CPU fan on a stock CPU heat sink. Can we do better?

Is an improvement available that results in lower CPU temperatures and near-silence fan performance?

One CPU cooler that I am impressed with is the Cooler Master Hyper 212 EVO. Whenever I build or upgrade a Linux system, I usually purchase one of these little marvels because it works reliably well with almost no noise.

I upgraded the stock AMD CPU cooler on a Linux system using an APU in an FM2 socket because it was too noisy and inefficient. What did I replace it with? Why, the Hyper 212 EVO, of course!

Here are some pictures…

VeraCrypt and Encryption Algorithm Performance

📅 February 27, 2017
cover“Does VeraCrypt slow down reads and writes?”

Do you want to encrypt your data, but are you concerned about a performance drop?

I was curious to find out if using VeraCrypt resulted in slower reads and writes for whole disk encryption with an external USB drive and for a standard file container, so I performed my own tests in Linux Mint 18.1.

How would the different encryption algorithms affect performance? Are some faster or slower than others?

Here are my results…
