Have a look at ThisOldTony as well - he's an amateur metalworker who explains things really well.

I got used to that the day I looked for some fun takes on N*zi propaganda (i.e. the video of Born to be Alive with Mr. Moustache "dancing" to it) but of course YouTube collected it under N*zi videos.
Alongside black metal, swords, guns, explosives. So yeah, I am on at least a dozen no-fly lists.

Tom Scott's channel is highly recomended, esp if your a brit.

I watch his videos occasionally, he's fine but a bit all over the place, I prefer very specific channels with in depth explanations. Though Tom Scott often piques my curiosity with interesting trivia.

As an ex-embedded engineer (retired now), I love bit twiddling and fast approximations. I never need this particular approximation but it's very clever and probably not something I'd ever figure out on my own.

Interesting, but I have some doubts it is still relevant with modern compilers and CPUs. Even if it were, a simple lookup table would be faster for the purpose of finding the first estimation.
This algortihm reminds me a bit of Bresenham's line algorithm - Wikipedia[^] : extremely clever, but once it was hard-wired in every graphcs chip there was little point knowing about it. Except maybe to apply such principles to similar problems in other areas.
E. g. I tend to do calculations with 2D and 3D vectors a lot, and if I were to do these calculations straightforward, then yes, I'd need to do a lot of vector normalizations (i. e. calculations of 1/sqrt(x)). But in about 8-9 out of 10 cases I can avoid normalization alltogether by transforming the expressions. E. g. when I want to know whether a vector length is very small (effectively null), then I compare the squared length against the squared threshold value. Or when I calculate the intersection of a plane with a line, I determine the intersection without normalizing any vector. Instead I transform the equations in such a way that I end up with the squared length of the line direction vector, and the plane direction or normal vectors don't need to be normalized at all.
I do agree that the explanations and specifically the animated number representations are formidable, though
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)

Found this great tip in a Dutch computer magazine:
Quote: You might have some (network)devices that have leds on top to display their status, which might not be visible when tucked away somewhere. To make the leds better visible from a distance take the balls out of some deodorant rollers and place these on top of the led lights
|
|
|
|
|
Or you might have one like my AC1750[^] that puts up a light show like a Christmas tree. The solution is a piece black electrical tape.
Come to think of it, deodorant balls and electrical tape might be, for light problems, what duct tape and WD40 are for mechanical design

To put it in the words of CodeWraith:

If you just want to disable the nightlight feature while still having statuses visible when needed, I've found LightDims a good solution.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

I recently attempted for the first time to ZIP some files I was surprised that each file and directory I selected was placed in the base root of the ZIP file I naively assumed the ZIP program and I have tried several to wit 7-ZIP Zip Free WinRAR and WinZip would place them into the root which is common to them all I utilized the Relative Paths setting for each entry I required this common root arrangement because these are source files utilized in a Visual Studio solution so their paths relative to each other needed to be unchanged The solution I finally decided upon was to copy each of the target files into a separate common root directory and then to simply emplace this directory into the ZIP file and Voila it worked However I still believe it is stupid to be required to do this So either I do not understand how to distribute software using ZIP or people have been enduring this copy requirement w/o complaint If that is the case I am fantasizing of writing a ZIP program which provides the option of calculating the common root so there is no need to perform the aforementioned copy So I seek your advice in telling me what is wrong w/ my fantasy Thank You Kindly

Let's agree that you don't distribute software using ZIP. You might send it to a friend, on a very occasional basis but software distribution is done using other, more appropriate tools like NSIS or something similar.
End of lecture 
The quick way I zip a tree is to right click on the root folder and "Send to -> Compressed (zipped) folder"

Thank you for informing me of NSIS Maybe it will come in handy However the purpose of my ZIP was to provide project files to Visual Studio support for the purpose of duplicating an apparent error in VS rather than the installation of executables which NSIS seems to be utilized for Thank you also for informing me I need not have purchased WinZip - Cheerio

I can recommend Inno Setup, see: installers-for-windows-programs[^]
Sadly I was forced to write an installer in C# that uses .zip files, felt like re-inventing the wheel

Good point .. I use it for about 10 years now for all kinds of deployments. Tolerance to Pascal is handy in this case, it was stimulating for me to look deeper into Pascal, which is interesting ...

I used SharpZipLib to compress some files into folders.
Creating a ZipEntry with a relative path (e.g. Info\readme.txt) would create a readme.txt file in the Info folder. You would then write the file contents to the zip file.
Good luck getting something working.

I think there is a good answer elsewhere, but if you find yourself doing this repeatedly where you want to exclude sensitive data files, etc.
For extremely complicated inclusion and exclusion rules in a folder hierarchy, the very old Ant build <jar> and <fileset> tags let you build powerful inclusion and exclusion rule sets with recursion to build a jar/zip.
You can use macros or templates for standard cases to generate the filesets.
