The pink bag shown is actually a static dissipative bag, not a static shielding bag, so would not be expected to work. Though the article mentions trying other bags so no doubt some of those where static shielding (metallic appearance) bags

Most video codecs, including H.264 and H.265, encode in frequency space (after DCT transform) on a block-by-block basis, discarding high-frequency information (the edges of text and graphical elements are high frequency information). That&#

I don't believe I have made any factually incorrect statements, but please enlighten me if I have. Have a look at the following two encodings of the same screen recording from the article, compressed to the same file size and the same

As another example the encoder at https://compress-or-die.com does a quite impressive job at compressing the GIF if allowing some loss of visual quality. Taking the number of colours down to 14 and allowing lossy compression I

Yes, in the GIF format you can update just a window inside the image rather than the whole image for each frame. There are also control blocks that specify that a particular colour value is to be treated as transparent (within the logical

Yes indeed all modern video codecs are based on encoding differences between key frames. GIF has the most basic implementation of that (it can update only a window in the image instead of the whole image). The original GIF can actually be c

That's actually not correct, GIFs can encode the differences between frames and quite efficiently for screen recordings. A GIF will be more efficient for a screen recording so long as there are small changes between frames.

For a screen recording of a UI, it's the perfect format unless you're demoing a video/photo editing application. You don't need alpha or many colours and screen recordings are quite efficient in a GIF.

by janekm 5y ago
Not for screen recordings, unless you're doing a screen recording of photos or videos a GIF will typically be more bandwidth efficient (as there will be large areas of single colours and few changes between frames which GIF is good at)

A dithered image tends to produce very short runs of pixels so is likely to get poor compression with RLE. Ordered dithering with a compression algorithm that can compress "words" (repeated patterns) (like the LZW in GIF) will per

True, and then every variant in every package version. But it does cause problems in the current climate as each of those variants do have to make it through the production pipeline (after die fab) which is also constrained at the moment.

Sadly your experience matches some of my own (in particular there are companies which purely exist to take part in these funding programmes which is a bit of a perversion of the aims). There are some great exceptions, and it's unfortun

That's not too far off from how EU funding programmes work (slightly different structure to the funding rounds but similar idea). LIFE which is one of the current programmes targeting climate change has a current budget of €5.43 billio

LiveView (I think) already achieves this optimisation as both the initial content and any future updates come over the same persistent websocket connection.

It's a fair point (and the same objection could be made to Swift's ! and ?). Over time I have given up my objections to verboseness... Clarity of code is far more important than conciseness. I do see the point for some syntactic s

I think it's pretty apparent that they are using a "body model" for the body as well which is kind of interesting in itself... It used to be that we'd use CG characters to replace the body of actors, now it's the o

Not just the microcontroller but also the wifi radio and antenna... But a USB-A socket is pretty big anyway. This isn't too different from the tiny wireless mouse dongles that have been around for a few decades.

A lot of what is commonly called cellophane is sadly not actual cellophane (actual cellophane is kind of crinkly, like old-fashioned clear candy bags). It's been replaced by polypropylene in most use cases as far as I can tell.
