From the man page: --ultra: unlocks high compression levels 20+ (maximum 22), using a lot more memory. Regardless, this reproduces with random other files and with '-9' as the compression level. I made a mastodon post abo

It seems like zstd is somehow compressing really badly when many zstd processes are run in parallel, but works as expected when run sequentially: https://news.ycombinator.com/item?id=46723158 Regardless, this does not make

Okay now this is weird. I can reproduce it just fine ... but only when compressing all PDFs simultaneously. To utilize all cores, I ran: $ for x in *.pdf; do zstd <"$x" >"$x.zst" --ultra -22 & done; wait

No, it can't. No LLM can purchase the equipment and chemicals and machinery you need to reproduce experiments, nor should you want it.

I just did some interactive shell loops and globs to compress everything and output CSV which I processed into an ASCII table, so I don't exactly have a pipeline I can modify and re-run the tests with compression speeds added ... but I

I'm not sold on the idea of adding compression to PDF at all, I'm not convinced that the space savings are worth breaking compatibility with older readers. Especially when you consider that you can just compress it in transit with

Isn't zstd primarily designed to provide decent compression ratios at amazing speeds? The reason it's exciting is mainly that you can add compression to places where it didn't necessarily make sense before because it's a

EDIT: Something weird is going on here. When compressing zstd in parallel it produces the garbage results seen here, but when compressing on a single core, it produces result competitive with Brotli (37M). See: https://news.ycomb

Neither $X nor $Y are going to be hard dollar values. If I semi-arbitrarily pick some $X and some $Y, put in $X+$Y as my max bid, and lost the item due to $0.01, I would be annoyed not due to some irrationality but because $X and $Y were

No, I am willing to pay $0.01 more but not infinity more, there's a difference

Before I have made that initial decision, and before I have invested resources into evaluating what I think the value of a product is, I do not have a price in mind. Deciding on a price I think is fair for a product takes effort. The more

> But if you set a max price at $5000 and would be happy to get the item at $5000.02 (for some reason other than satisfaction from sniping), then you set your max price wrong, or at least differently from how economists expect you to set

Regarding the last part: it's simple, $1.01 is less than $100 This process doesn't work endlessly. You can't just add $.01 a billion times and I'd still pay it. But it works once or twice. Shops set prices like $499.99 d

The gap between total indifference and wanting something bad enough to bid on it is always going to be more than $.01.
828.

It can be extended forever in theory, and sure, that is an interesting philosophical discussion, but it isn't in practice. We're discussing sniping. That means you make the choice once : do I send in a last-second bid that's
829.
by mort96 9mo ago
The logic of "you shouldn't ever need to snipe, just bid your max price" only works if we assume that the max price is a red line though. If I "value something" at $5000 (as in I want to buy it at $5000), and I bi

by mort96 9mo ago
I don't see why I would buy something if I'm indifferent to whether I buy the thing.

by mort96 10mo ago
I don't understand this line of reasoning. I don't do auctions, but if I did, it would be because I want that item. When I want something, I never have an absolute hard price ceiling; if I'm willing to pay $10000, I'm wi

HDR support is an anti-feature. Nobody want a part of a website to suddenly be 10x as bright as pure white.

It's so annoying how so many languages lack a basic "ASCII lowercase" and "ASCII uppercase" function. All the Unicode logic is not only unnecessary, but actively unwanted, when you e.g want to change the case of a h

I work on games sometimes, where the goal is: "run as fast as possible on everyone's computer, whether it's a 15 year old netbook with an Intel Atom or a freshly built beast of a gaming desktop". As a result, the best ap

Regarding (b), I would never rely on auto vectorization because I have no insight into it. The only way to check if my code is written such that auto-vectorization can do its thing is to compile my program with every combination of compiler

It goes through the "reject all tracking" flow. Other solutions automate clicking "accept all tracking" (since that's usually simpler), or just hide the pop-ups.

Yeah, as I said it's a solvable problem. It just needs solutions to be implemented
