The Pentagon has added Alibaba, BYD, Baidu, Unitree, and other Chinese companies to its list of firms it says support China's military, barring them from U.S. defense contracts. The companies and China's embassy deny the allegations. The Associated Press reports: Created in 2021 by a congressional mandate, the list (PDF) seeks to identify Chinese companies that the Pentagon considers to have links to the Chinese military -- not only those directly controlled by the Chinese military and security forces but also those contributing to the country's defense industrial base. When updating the list last year, the Pentagon said the Chinese military sought to acquire advanced technologies and expertise developed by Chinese companies, universities and research programs that "appear to be civilian entities." The Chinese Embassy on Monday accused the U.S. of "overstretching the concept of national security and making discriminatory lists to go after Chinese companies." It said Chinese companies observe the laws and regulations of the countries where they do business. "The U.S. should stop its wrong practice and create a fair, just and non-discriminatory environment for Chinese companies," the embassy said in a statement.

So apparently rsync is slop now. When I heard, I wanted to drop a quick note on my blog to give an alternative: tar. It doesn’t do everything that rsync does, in particular identifying and skipping up-to-date files, but tar + ssh can definitely accomodate the use case of “transmit all of these files over an SSH connection to another host”.

Consider the following:

tar -cz public | ssh example.org tar -C /var/www -xz

This will transfer the contents of ./public/ to example.org:/var/www/public/, preserving file ownership and permissions and so on, with gzip compression. This is roughly the equivalent of:

rsync -a public example.org:/var/www/

Here’s the same thing with a lightweight progress display thanks to pv:

tar -cz public | pv | ssh example.org tar -C /var/www -xz

I know tar is infamously difficult to remember how to use. Honestly, I kind of feel that way about rsync, too. But, here’s a refresher on the most important options for this use-case. To use tar, pick one of the following modes with the command line flags:

• -c: create an archive
• -x: extract an archive

Use -f <filename> to read from or write to a file. Without this option, tar uses stdin and stdout, which is what the pipelines above rely on. Use -C <path> to change directories before archiving or extracting files. Use -z to compress or decompress the tarball with gzip. That’s basically everything you need to know about tar to use it for this purpose (and for most purposes, really).

With rsync, to control where the files end up you have to memorize some rules about things like whether or not each path has a trailing slash. With tar, the rules are, in my opinion, a bit easier to reason about. The paths which appear on the command line of tar -c are the paths that tar -x will open to create those files. So if you run this:

tar -c public/index.html public/index.css

You get a tarball which has public/index.html and public/index.css in it.

When tar -x opens this tarball, it will call fopen("public/index.html", "w"). So, whatever tar’s working directory is, it will extract this file into ./public/index.html. You can change the working directory before tar does this, on either end, by passing tar -C <path>.

Of course, you could just use scp, but this fits into my brain better.

I hope that’s useful to you!

Update: As a fun little challenge I wrapped up this concept in a small program that makes it easier to use:

Example:

xtar -R /var/www me@example.org public/*

Oh no. Anyway

On Friday, government lawyers in the lawsuit filed a court record which said they asked the plaintiffs to remove the videos "from the internet due to concerns that the publication of the videos could subject the witnesses and their family members to undue harassment and reputational harm." The filing then said that Fox specifically "has been subject to harassment and has received a number of death threats since the videos and video clips were publicized and circulated."

It is with great pleasure, relief and waiting that we can finally announce Death By Scrolling, one of the most anticipated games of 2025.

FastMail is a good, Google-free provider of e-mail, calendar services, and the like. But it isn't the only one, and it's due for a price increase in 2025. Is it time to switch?

With macOS 26 Tahoe this year, Apple introduced a new Control Center. Of course, it implements the new Liquid Glass design seen across the entire ecosystem, but it also brings a brand new feature to the Mac for the first time: third-party integrations.

That, on its own, is a big deal, and was a greatly appreciated feature of iOS 18 last year. However, it has an even bigger implication for the Mac.
