Parsing JSON at compile time with C++26 static reflection

Suppose that you have a configuration file in JSON. Something like this: { "width": 1920, "height": 1080, "fullscreen": true, "title": "My Game", "volume": 0.8 } Normally you ship this file alongside your program, open it at startup, read it, and parse it.…

Active AUR malicious packages incident

We are currently experiencing a high volume of malicious package adoptions and updates in the Arch User Repository.

We are actively working to track down existing malicious commits and attempting to prevent additional malicious commits from being pushed. While this is happening, and while we work to create a more permanent solution, users may see issues with the following:

● Creating new accounts on the AUR
● Pushing package updates
● Adopting or creating new packages

We continue to encourage all users of AUR packages to review all PKGBUILD and install script changes when updating, especially during this time. If you notice suspicious commits to a package that you use, please reach out to Arch staff via the aur-general mailing list with more information.

6000 端口占用导致 SLURM 卡死诊断一例

今天在组里的某个 GPU 集群上部署了一套 SLURM，方便多人使用。我本以为只是从已有集群复制配置、启动服务，十分钟之内就能搞定，没想到因为一个玄学的问题整整卡了一个多小时。 问题现象：各个节点上的 slurmctld、slurmd、slurmdbd 都能正常启动，然而只要试图提交任务，机器上的 slurmd 和派生的 slurmstepd 就会卡死（任务并没有开始运行），不再有任何响应（slurmctld 也无法联系它），只能靠 SIGKILL 杀死后重新启动。各个进程的日志中都看不出什么异常；能看…

Embodied cognition and agentic AI

Where is your intelligence located? In your brain? It is a simplistic answer. A better model is that your intelligence is embodied. Consider a cook working at an expensive restaurant. He has all his favorite knives and cooking instructions, placed exactly…

Breaking changes for all users of `varnish`, which is renamed to `vinyl-cache`

The Varnish project has renamed itself to Vinyl Cache. We followed this rename with a new vinyl-cache package. This upgrade results in breaking changes and users are advised to study these changes and how it affects them before following the replacement. All references to "varnish" have been changed to "vinyl" in all binaries and directories.

At minimum, users will have to:

● rename /etc/varnish to /etc/vinyl-cache
● rename /var/lib/varnish to /var/lib/vinyl-cache
● fix up ownership of files inside /var/lib/varnish
● user varnish becomes vinyl
● group varnish becomes vinyl
● user varnishlog becomes vinyllog
● user vcache remains the same
● disable the old varnish.service and varnishncsa.service systemd units
● enable the new vinyl-cache.service and vinylncsa.service systemd units

Meanwhile, the varnish package has been dropped from [extra]. We're not currently planning to maintain a new varnish package as it's a different upstream project.

In software programming, the product between two integers is often computed to a fixed number of bits with overflow. Consider 8-bit integers. If you multiply 127 by 127, you get back the number 1 as an 8-bit unsigned integer, with an overflow. The actual…
