64-bit Windows = 64-bit Java?

Here's one of those counter-intuitive situations that give tech such a bad name and make even an experienced user such as yours truly (with over 20 years of IT involvement) want to throw my arms up in despair. If you are running a 64-bit version of Windows, which version of Java should you install? The 32-bit or 64-bit variety? If you choose 64-bit, you are wrong!

Take a look at this little snippet of information at the official Java website. If you are planning to use Java in your browser (IE, Firefox or Chrome), you'd better install the 32-bit version of Java. The reason is because most browsers are still 32-bit, and they can't access the Java runtime if it is 64-bit. And as far as I know, the 32-bit and 64-bit versions of Java cannot co-exist on the same system, so 32-bit is really the only way to go.

You probably only install the 64-bit version of Java on servers where you need the extra "omph" and in-browser Java support is not required. For the rest of us, we have to live in this totally counter-intuitive, crazy world of 32-bit Java within 64-bit Windows!

Update: Line adapter for Ozito Blade Trimmer

Update (Dec 2021): If you access to a 3D printer, I would now recommend this solution , which makes it super easy to replace the trimmer line. I have been using it for a few months now with zero issue.

3D Printer Filament Joiner

I have been looking at various ways of joining 3D printing filaments. One method involves running one end of a filament through a short PTFE tubing, melting it with a lighter or candle, retracting it back into the tubing and immediately plunging the filament to be fused into the tubing: One problem with this method is that you can't really control the temperature at which you melt the filament, so you frequently end up with a brittle joint that breaks upon the slightest bend. Aliexpress even sells a contraption that works along the same line. As it uses a lighter or candle as well, it suffers from the same weakness. I am not even sure why you need a special contraption when a short PTFE tubing will work just as well. Another method involves using shrink tubing/aluminium foil, and a heat gun: But a heat gun is rather expensive, so I wanted to explore other alternatives. The candle + PTFE tubing method actually works quite well when you happen to melt it at the rig
