I decided to write a web-based brainteaser puzzle after seeing a puzzle in the August 2023 Mensa Bulletin that reminded me of an electronic game that I liked to play many years ago. I decided to recreate that game using the layout and rules of the Mensa puzzle.
I have since made this daily puzzle available to the public and here it is: FlipIT
In this blog article, I will discuss some of the design aspects of this program/web-app.
Using gradients in Excel is not just to make your spreadsheet pretty. This type of conditional formatting makes it easy to see correlations and meaning in your data. You can see that put to use in my article on RAM Latency VS Clock Speed. In this followup article, I show exactly how that gradient was created.
It is hard to believe that Excel still doesn't have the built-in ability to display a cell split diagonally with independent labels in each half. There are several ways to solve this manually but with issues. The two main issues are that resizing cells can mess up some solutions and most solutions do not allow you to color each half independently.
This article demonstrates two complete solutions - one is an add-in that I built and the other is a manual process to do the same thing.
You may have noticed that when faster memory first becomes available, it comes with a higher latency than similar existing RAM. Why is this, and how does that affect overall performance? Also, when you overclock RAM in the BIOS, you will get much better results if you adjust the CAS latency at the same time. But how do you know what value to enter for CAS? And what if motherboard limitations require that you use a lower-than-specified RAM speed? Did you know that you then get to use a lower value for CAS?
This article will answer these questions, and includes formulas and charts so you can feel confident in your RAM purchase and use the correct settings.
