Hardware stores sell denatured alcohol as a cleaner, a fuel, or a solvent. What does denatured mean? What’s the difference between denatured and other alcohol, such as what you find at a drug store, or the liquor store?
Denatured alcohol is ethanol, sometimes as little as 50 percent by volume, mixed with other chemicals to make it undrinkable. It has an unpleasant smell and taste, and drinking it can cause nausea, blindness, or even death.
I’ll argue with anyone that WHIP is the most fair statistic when it comes to measuring a pitcher’s success. What WHIP measures is how many base runners a pitcher allows in an average inning.

When talking about retro computers or any other collectible, sometimes you’re run into the term period correctness. What does period correct mean? In this blog post, I’ll talk about the concept and give some examples from a couple of different hobbies.
Period correctness is simply a term that means correct for the era. It means that an accessory or add-on came from the same era as the item you are using with, and the two items likely would have been used together when they were new.
My WordPress has been acting strange for a while, missing scheduled posts and other general weirdness. I eventually traced the problem to a file called wp-cron.php. Here’s how I automated wp-cron.php to improve WordPress speed and reliability.
The Media Vision Pro Audio Spectrum 16 was a popular 16-bit sound card in the early 1990s. It attempted to do to Creative Labs what Creative had previously done to Ad Lib. When it didn’t meet that goal, the company became infamous for securities fraud. Two of its executives served prison terms.
I helped my son replace the i5 CPU in his PC with an i7 to hopefully solve some occasional performance problems he was having.
