A thing I do not like is when a computer form has a drop-down menu of every country in the world, and you select it and type "CAN", and it selects Namibia because Namibia begins with N

@mcc I really enjoy when a drop-down list has all the US States (would also work for Canadian provinces) with their names spelled out but sorted internally by their abbreviations because that's how it is stored in the database.

Light Following Robot Does It The Analog Way
If you wanted to build a robot that chased light, you might start thinking about Raspberry Pis, cameras, and off-the-shelf computer vision systems. However, it needn’t be so complex. [Ed] of [Death and the Penguin] demonstrates this ably with a simple robot that finds the light the old-fashioned way.
The build is not dissimilar from many line-following and line chasing robots that graced the pages of electronics magazines 50 years ago or more. The basic circuit relies on a pair of light-dependent resistors (LDR), which are wrapped in cardboard tubes to effectively make their response highly directional. An op-amp is used to compare the resistance of each LDR. It then crudely steers the robot towards the brighter light between turning one motor hard on or the other, operating in a skid-steer style arrangement.
[Ed] then proceeded to improve the design further with the addition of a 555 timer IC. It’s set up to enable PWM-like control, allowing one motor to run at a lower speed than the other depending on the ratio between the light sensors. This provides much smoother steering than the hard-on, hard-off control of the simpler circuit. [Ed] notes that this is about the point where he would typically reach for a microcontroller if he hoped to add any additional sophistication.
In an era where microcontrollers seem to be the solution to everything, it’s nice to remember that sometimes you can complete a project without using a processor or any code at all. Video after the break.

"OK, Google. Navigate to Osaka Grill."
There is a restaurant named "Osaka Grill" that is 11 minutes away from my home.
There is a restaurant named "Osaka" that is 29 minutes away from my home.
Before Gemini, Google Assistant was smart enough to figure out that I meant the place with the stated name that is closer to me, not the place with a similar name that is farther away.
The more AI they add, the dumber it gets.

In a pagan folk band AND a pagan metal band? I have doubts about Biko.

I think one of the things I like about this show is that I enjoy planning and preparing for trips (or any activity, really) possibly more than I enjoy the trip itself. Planning for a survival situation? 🤌

@aeva Put the ubuntu iso image on a usb key and insert it into the computer is all it takes, should be similar on other distros.
netboot.xyz is nice. It's a bootable image which brings up a menu of linux distros to try or install, fetching them over the internet. Install it on a usb key, boot drive, or network boot file.

Grazie ho letto la prima parte, spiegazione molto interessante, mi sono venuti dei dubbi, magari mi si chiariranno leggendo il resto.

Alone season 8 watch thread. I hope there are less dead mammals, especially big ones, than in season 7. Not only is it nearly always a suboptimal strategy, it's depressing.
