1·2 months agoIt seems that we focus our interest in two different parts of the problem.
Finding the most optimal way to classify which images are best compressed in bulk is an interesting problem in itself. In this particular problem the person asking it had already picked out similar images by hand and they can be identified by their timestamp for optimizing a comparison of similarity. What I wanted to find out was how well the similar images can be compressed with various methods and codecs with minimal loss of quality. My goal was not to use it as a method to classify the images. It was simply to examine how well the compression stage would work with various methods.
Wait… this is exactly the problem a video codec solves. Scoot and give me some sample data!
I was not talking about classification. What I was talking about was a simple probe at how well a collage of similar images compares in compressed size to the images individually. The hypothesis is that a compression codec would compress images with similar colordistribution in a spritesheet better than if it encode each image individually. I don’t know, the savings might be neglible, but I’d assume that there was something to gain at least for some compression codecs. I doubt doing deduplication post compression has much to gain.
I think you’re overthinking the classification task. These images are very similar and I think comparing the color distribution would be adequate. It would of course be interesting to compare the different methods :)
The first thing I would do writing such a paper would be to test current compression algorithms by create a collage of the similar images and see how that compares to the size of the indiviual images.

There are a lot of entertaining articles on Techdirt about companies not understanding trademark law.
The C compiler or third party libraries can provide support for parallel execution and SIMD. That article is just used by people in an attempt to argue that C’s strength in being a good low level abstraction is false, which it isn’t. C is the best portable abstraction over a generic CPU that I know of. If you start adding parallel features and SIMD like the article suggest, you’ll end up with something that’s not a portable low level abstraction. To be portable those featues would have to be implemented in slow fake variants for platforms that doesn’t support it. We can always argue where to draw the line, but I think C nailed it pretty good on what to include in the language and what to leave up to extensions and libaries.
C is not a perfect abstraction, because it is portable. Non portable features for specific architectures are accessed through libraries or compiler extensions and many compilers even include memory safe features. It’s a big advantage though to know Assembly for your target platform when developing in C, such that you become aware fx. that x86 actually detects integer overflow and sets an overflow flag, even though that’s not directly accessible from C. Compilers often implement extensions for such features, but you can yourself extend C with small functions for architecture specific features using Assembly.
Does anyone know of a list of TLDs that don’t allow reselling? I’d prefer to buy/lease one of those and let domain sharks play their own games.
I use gitit and it’s already packaged in most Linux distros.
TLDR; Sorta federation. It is possible to selfhost data.
Yeah, that container probably crashed because of atmospheric disturbance.
I use Devuan and it’s just Debian without systemd.
Gothub is looking for a new maintainer.
If you still want to respect user privacy, your analytics software could use the port of the connection instead of IP as the identifier. It would be perfectly fine for determining simultaneus users from the same IP, but not invasive enough to monitor an individuals behaviour. Don’t ask me which analytics software supports that. I’d grab the data from the http logs if it was me and use a tool like goaccess.

Also these are worth mentioning:
- Mojeek have their own index. The results are occasionally a bit of a mess, but they are very open to input and have an account on Mastodon.
- Infotiger have their own index and the results are good.
- Alexandria which use the Common Crawl index.
I use gitit from the Debian repositories. It’s a simple server application without a database and it uses git and pandoc. I just run
gitit -f somewiki.confand access it in the browser. As formatting you can use what pandoc supports, but I’ve chosen reStructuredText. DokuWiki mentioned by others in the thread is also a good option.
Depends on your country, but where I live Open Streetmap is better than Google’s map. I hear OsmAnd is a great app, but I don’t use a smartphone so I haven’t tested it. I just know that their very compact offline maps are impressive.
It’s easy to overlook with the omnipresent internet, but self-hosting doesn’t require internet. You could host for your fellow students on the local network. If that’s also against the Wifi rules you can either ignore that stupid rule or set up your own god damn wifi with hostapd on your machine and let students connect directly to it. It’s probably best to use a machine dedicated to the task for security reasons as you wouldn’t want curious students to accidentally erase your homework. I wouldn’t use containers or VMs for any of this, I’d just use bare metal like in the good ol’ days. You could also, without having to worry, give people shell accounts because it’s a closed network. The options are endless without all the worries of hosting on the internet.
