Fixing our own problems in the Rust compiler

In our data compression projects, we use Rust where C is traditionally used. During the work, we've hit limitations in Rust itself and in the surrounding tooling. Over the years, we've become increasingly comfortable with fixing these issues ourselves. […]

1. Submit a pull request to #zlib that changes the library filename on #Windows.
2. Pull request gets merged, and you effectively break everything that linked dynamically to zlib.
3. Attack everyone who reported this as a bug.

There is a critical security vulnerability in zlib that allows code smuggling. Currently, there does not appear to be an update available.

I'm guessing you need physical #books ?

I download all my out-of-copyright books from #zLibrary #LibraryGenesis or #AnnasArchive . I've found it a very effective approach.

Otherwise perhaps www.abebooks.com on which used book sellers seem to list all their books. I believe it's amazon-owned, so if anyone knows of alternatives, I'd be all ears!

I can't use the v3 mail-compress and I can't use the scripts flying around, so I wanted to do it using on-board tools of dovecot.
#Dovecot #zlib #dsync #help

#Dovecot Does anyone know how I can use the #zlib plugin to compress my mail archive while transferring from another server? I tried to set it up, but the mail just comes over as-is. The docs suggest that it should convert with #dsync to compressed files. I seem to miss something. #help

Today I had a quick look at compression speed of the various compression algorithms in #UnrealEngine.

In my use case, speed is more important than compression ratio, so I had COMPRESS_BiasSpeed set.

To little surprise, #gzip and #zlib took about the same time, and #lz4 was a lot slower.

The big surprise was #Oodle, which was faster than all others. By a lot.

So, if you are compressing data in your Unreal game at runtime, you might want to check if Oodle is an option for you.

zlib、gzip 與 zip 的關係 (Mark Adler 的回覆)
