There's a TOCTTOU going from the filename to the file handle, but once you have a handle, - on Windows, another process deleting the file is prevented (unless you explicitly opted-in to cooperative FILE_SHARE_DELETE); and - on Linux, a

Is your FIPS .dll/.so publicly available? It's surprisingly hard to get FIPS crypto in Golang on Windows.

Just a theory: containerized backends gave developers much more freedom of choice to pick technologies that happen to work better with SQLite. Go and Rust work great with SQLite because all the concurrency is mediated within a single applic

This is days later, sorry, but - you can't use an interface as a map key, so this shouldn't apply, right?

Cgo is a real option here, or at least would be an interesting comparison. The function is likely called with large enough data to amortize the (few ns) overhead and it's certainly more maintainable. Another option is GOAMD64=v3 /

Is this really the case? Can you link to anything or an example on go.dev/play/ ? I can find a mention of "cmp.Equal" having that behavior, but that's just a third-party package panic.

This was fixed recently in Linux by Matthew Wilcox and others, in a way that can benefit all Linux filesystems. Folios of pages were added in 5.16, the page cache was converted to use folios in 5.17, and large-folios were in 5.18.

It's not possible to fix the first one (to merge the ARC with the Linux page cache), because the necessary page cache internals are GPL-only.

Btrfs RAID 5 is "fixed" as of kernel 6.2 - see https://www.phoronix.com/news/Linux-6.2-Btrfs-EXT4 Although I'd still suggest single-block-device-btrfs on mdadm instead. The per-file RAID in btrfs (/

Thank you and sorry for detracting from the point of your very interesting article. I'm using Chromium 108 on Debian - i can see the scrollbar appear fine in Firefox 102.

Sorry - if this is your website, could you please not hide the scrollbar? The CSS file has a comment This below keeps the regular scrollbar for scrolling the page, if present, because that one makes sense to be there. but it doesn't

Most of the bracket lines are space-indented and most of the if lines are tab-indented - likely GitHub rendering with 8-space instead of 4-space tabs is making it look worse than intended,

Samba outperforms ksmbd anyway - https://samba.plus/blog/detail/ksmbd-a-new-in-kernel-smb-ser... The main reason to use ksmbd is if you can't use GPLv3 Samba. Most PC SMB servers will still be using Samba ins

Most of Go dependencies these days come from your $GOPROXY, which by default (proxy.golang.org) is available over IPv6 just fine.

The built-in one actually sleeps and polls to check if the write lock is free again. It's a disaster for high write throughput. https://sqlite.org/forum/info/00312b3d02bc0583 Sqlite's internal one has to

Go + SQLite user at $DAYJOB here. WAL is essential, and the next essential trick is to open a single db.Conn up-front and hide that behind a mutex for any transactions/queries that will write. All callers can pick this.db_rw or this.db

Zstd's decoder is very very fast for what it does, what ideas do you have to improve it? It's unlikely to beat lzo family on decompression speed, but that's a different class of compressor entirely. And probably there are sti

Definitely look into Chinese technology here, they're much further along this curve. Not just ss but also xray/v2ray, cloak, goodbyedpi, trojan-gfw etc.
