How does JAX allocate memory on a TPU?

jnp.device_put(1) is deceptively simple to write in JAX. But on a TPU, what actually happens? How does a tensor containing the value 1 actually get onto a TPU?

Turns out, the answer is "C++", and a lot of it.

Verify downloaded GPG installation package

1. Download GPG (GPG Binary releases) and *.sig file.
   • Windows: GnuPG simple installer (CLI tools)
2. Import GnuPG public keys with verified gpg binary.
   • Use gpg that comes with Git installation from Git Bash

     where gpg
     gpg --version

I saw this poll on Twitter earlier and was surprised at the result, which at the time of writing overwhelmingly favours option 1:

I've always been of the opinion that the (req, res, next) => {} API is the worst of all possible worlds, so one of two things is happening:

• People like familiarity

I used a FreeBSD 11 VM runing on GCE

To get Linux exe's working on BSD

• compile with dart2native, eg I used DSG from a zip of exe's built here: https://github.com/maks/dsg/actions/runs/198892581
• sudo brandelf -t linux exe-filename
• edit /etc/rc.conf and add: linux_enable="YES"
• then: sudo service abi restart
• cd /usr/ports/emulators/linux_base-c7 then make install

One liner for deleting images from a v2 docker registry

Just plug in your own values for registry and repo/image name.

registry='localhost:5000'
name='my-image'
curl -v -sSL -X DELETE "http://${registry}/v2/${name}/manifests/$(
    curl -sSL -I \
        -H "Accept: application/vnd.docker.distribution.manifest.v2+json" \
