Ever since I saw this, I’ve been fascinated by the memory chimps seems to have. And also the fact that they clearly can learn and understand numbers. It’s wild that they can do this, and it really makes you question how the brain actually works.
Chess is best OTB
Although chess can be played online, it is best played over a board. To get even more out of the games, I have created a webapp to record the moves along the way. It is designed for training and friendly games and give you the stockfish evaluation. However, not the actual variation. What the best move is, you have to figure out yourself. Unless you decide that you want a number of hints available.
The interface will rotate every half move, so you don’t have to turn the phone/tablet over.
Toptool T7 review
TOOLTOP T7 256*192 Android 25Hz Thermal Imaging Camera
Introduction
I’ve long considered getting a thermal camera, but until now, I never had a strong reason. While fixing some tiles, I needed to know exactly where the floor heating elements were. Finding good reviews online wasn’t easy—many just showed thermal photos of cats and coffee mugs. Fun, but not very helpful. This is a review from my own purchase; I have not received any benefits from TopTool or seller.
Here is my review and some real-world tests into how the Tooltop T7 actually performs, and whether it’s useful for jobs around the home, workshop, or electronics bench.
SnartCardWeb – now also for iPhone
When you’re at the checkout and the cashier asks for your phone number to apply loyalty club discounts, it takes a little extra time. A small thing, but the cashier is already holding a barcode scanner, and it can read your number with a simple beep. I’ve previously made both a paid and a free … Read more

Stop Checkout Chaos: Why I Built SnartCard
Love them or hate them, loyalty programs and store memberships are everywhere. While privacy debates often steal the spotlight, there’s a practical problem that drives me crazy every time I shop:
The scene you know all too well:
You’re at the checkout. “Are you a member?” asks the cashier. You rattle off your phone number… they type it wrong… you repeat… it fails… you find your phone to lookup your wifes number… it fails too… Time wasted. The line behind you grows. Everyone gets annoyed.
The problem? Almost every store uses your phone number as ID. The technology to make this simple exists—barcodes!—but the solution was missing.
How I solved the cube with just 4 algorithms
There are two approaches to solving rubiks cube you must choose from.
1. Find the solution yourself. Start with one side and solve layer by layer till your done. Find all the algorithms you need without help. This is the hardest way, but most rewarding.
2. Use an online guide to learn a method to solve the cube. This is the easy way, but once you go down this road you can never go back to the first option.
The best way to do option number two is to follow the beginners guide at SolveTheCube. You can also follow my method and read the rest of this post, but be warned it’s not really a guide. However my first method for solving the last layer is a bit different from the usual OLL/PLL methods, which other cube nerds might find interesting. Also I believe it’s the method with fewest algorithms to learn.
Easy fix for frayed laces
The small plastic at the end of the shoelace is called an aglet When they break or fall off, there are several ways to repair them. You can use tape, but it wont last long. You can use shrink plastic sleeves, tie together with sewing thread or other imaginative methods, but how much time and effort do you really want to spend on a shoelace?
DIY canned air
Warning: Compressed air is dangerous. You are responsible for your own safety. Fire extinguishers can cause massive damage if activated indoors.
Canned air is nice for blowing clean PCs and other things for dust, but the cost of those disposable cans quickly add up.
A fire extinguisher should be replaced or have an expensive service after 10 years. Service and refilling costs the same as a new one, so what to do with the old one? The short boring answer is to deliver it as special waste at the nearest depot, but are there better alternatives?
The tank of a standard fire extinguisher is usually rated at 15 bar. How about a handy compressed air tank for the small jobs where the compressor is cumbersome to carry around? Converting a fire extinguisher to a portable compressed air tank is easy and straightforward.
