Yes, it's more complicated, and parts of it might need hacks, as there are no standard way to get subpixel layout. That's a failure of those display APIs though, not the failure of the concept of subpixel-AA itself. > does it m

Pixel boundaries on your display are imaginary, all you have are RGBRGB light sources next to each other. The pixel boundaries are determined by your left-most and right-most light sources on the display, so you have |RGB|RGB|..., but it re

For me this feels like a candidate to build on top of fmt instead of a standalone thing, with a custom formatter wrapping JSON data. I think that direction of extension might still be open, while keeping the current interface for convenienc

If you only install supposedly non-conflicting packages, and there are conflicting file locations, isn't that a packaging bug?

Just to chip in what should the commit message say: it should express the intent of the change and the reason of the change (latter could be reference to ticket). I don't think expressing how the intended change is achieved is importan

Well sure. Try not to download them at the same time.

Editing once, with the approval of the authors is one thing. "Automatic" editing on each download is an other.

It probably doesn't worth the cost. Metadata can be trivially stripped, and altering the encoded video and audio streams for each user for fingerprinting is costly.

Then your tool is incomplete. Steganography works by encoding information into side channels, like precise positioning of words in the PDF, fonts, etc... Your tool can be as crude as running the document through pdftotext and only keeping t

I don't recommend normalizing differences, as in using both sources as input to produce one "cleaned" output. It could leave watermarks that happen to be the same in both sources. I recommend having a tool that works on a sin

You just pick a font and always replace with that.

To verify that a watermark removal method works: 1. Download the content with N accounts, preferably from different networks. 2. Run your watermark removal tool on each downloaded data independently. 3. Check if the processed outputs are bi

More generally if you want to redact pixels, then don't replace them with information that depend on those pixel values. It doesn't necessarily mean a black rectangle, but that's certainly simple and it works.

It's semantically slightly different. In the case of diff3 if you remove everything but the base part, then you get exactly the base version, while in the case of zdiff3 you also get the prefix and suffix parts from the two branches th

I don't know about Rust. Several people responded that Java already has a builder interface for creating a format string. That is possibly more type erased than the Rust macro equivalent. In C++ I would use variadic templates, as I ori

by steerablesafe 5y ago
That's perhaps true, but there is no reason why we can't have both. There are many hard-coded format strings in practice.

+1 for strongly typed and compile-time checked, but I'm still not a fan of a sub-language within a string literal. The language already has syntax to structure things, why make a separate language within strings?
83.
by steerablesafe 5y ago
Sure, the issue is somewhat orthogonal. But I assume they wanted to keep the format string parsing minimal, hence the single letter format specifiers. Once you have a strongly typed API, you are no longer bound by this and you can have sens

by steerablesafe 5y ago
Is it just me for thinking that using format strings instead of some strongly typed interface with verbose names for this is not great? I would take `format(year(), '/', month(), '/', day())` over ad-hoc format

It is for deterministically release resources based on scope (although Go's defer is tied to function-scope for reasons I can't understand). python's context manager is similar. Much like destructors in C++. You can probabl

by steerablesafe 5y ago
If you replace "short-lived objects" with "short-lived resources" then Go has defer, Python has context managers.

"echo" and "time" are explicitly bash built-ins, "which" and "cat" are not, and you will always get a process spawned there. Your second strace is misleading, you didn't trace child processes.

> especially since `cat` is often inlined, without process spawning. That would be surprising. How would that work? `cat` is definitely not a bash built-in.
