One of the first things I did when I started experimenting with SD was a series of “the Muppets attack paris” images, with explosions, crumbling buildings, police and military response, fleeing citizens… The cheeky gleeful looks on those muppets as they flee scenes of devastation are hilarious and some of my favourite images I’ve produced!

Correct me if I’m wrong

Well actually, yes, I’m sorry to have to tell you are wrong. Shannon-Fano coding is suboptimal for prefix codes and Huffman coding, while optimal for prefix-based coding, is not necessarily the most efficient compression method for any given data (and often isn’t).

Huffman can be optimal given certain strict constraints, but those constraints don’t always occur in natural/real- world data.

The best compression method (whether lossless or lossy) depends greatly on the nature of the data to be compressed. Patterns and biases can make certain methods much more efficient (or more practical) in some cases, when they might be useless elsewhere or in general. This is why data is often transformed before compression, using a reversible transformation that “encourages” certain desirable statistical characteristics in the data, so the compression method can better exploit them.

For example, compression software (e.g. gzip) may perform a Burrows-Wheeler transform and other encodings before applying Huffman coding to get a better compression ratio. If Huffman coding was an optimal compression method for all possible data, this would be redundant! Often, E.g. in medical imaging, audio/video data, the data is best analysed in a different domain to better reveal the underlying patterns and redundancies in the data so they cam be easily exploited by compression. E.g. frequency domain instead of time/spatial domain.

You don’t need to draw a line for this case. You just need to decide if 9 years is too long.

I understand the concerns about Google owning the OS, that’s my only worry with my chromebook. If Google start preventing use of adblockers, or limiting freedoms in other ways that might sour my opinion. But the hardware can run other OSs natively, so that would be my get-out-of-jail option if needed.

I’ve not encountered problems with broken support for dev tools, but I am using a completely different tool chain to you. My experience with linux dev and cross-compiling for android has been pretty seamless so far. My chromebook also seems to support GPU acceleration through both Android and Linux VMs, so perhaps that is a device-specific issue?

I’m certainly not going to claim that chromebooks are perfect devices for everyone, nor a replacement for a fully-fledged laptop or desktop OS experience. For my particular usage, it’s worked out great but YMMV, my main point is that ChromeOS isn’t just for idiots as the poster above seemed to think.

Also, a good percentage of my satisfaction with it is the hardware and form-factor rather than ChromeOS per se. The same device running Linux natively would still tick most of my boxes, although I’d probably miss a couple of android apps and tablet mode support.

People who use Chromebooks are also really slow and aren’t technically savvy at all.

Nonsense. I think your opinion is clouded by your limited experience with them.

ChromeOS supports a full Debian Linux virtual machine/container environment. That’s not a feature aimed at non-tech-savvy users. It’s used by software developers (especially web and Android devs), linux sysadmins, and students of all levels.

In fact I might even argue the opposite: a more technically-savvy user is more likely to find a use case for them.

Personally, I’m currently using mine for R&D in memory management and cross-platform compiler technology, with a bit of hobby game development on the side. I’ve even installed and helped debug Lemmy on my chromebook! It’s a fab ultra-portable, bullet proof dev machine with a battery life that no full laptop can match.

But then I do apparently have an IQ of zero, so maybe you’re right after all…
