Docker pulls entire image even if some layers were delivered with save/load
When saving an image from the graph-driver store, a new archive is created containing the uncompressed layers; saving/loading will produce the same layers as were pulled, but the save/load won’t include information about their compressed digests, because this information cannot be verified without the actual compressed artifacts (as pulled from the registry). Reconstructing the compressed layers is not possible due to compression algorithms not being 100% reproducible (they may be most of the time, but various factors, including CPU load, and CPU optimizations during compression can cause their checksum to differ).
"Amen" cadence
Cadence is the core tension in music theory. The most common one is called the authentic cadence - between V and I degrees of the scale. In blues however the cadence of IV to I is more typical.
Fun part is that IV to I is also called “Amen” candence, for its frequent use for “Amen” in hymns.
Brief comparison of Google Drive and Dropbox

- Dropbox $120 / year
Privacy
When I shared a file with someone, and then want to: unshare and share with someone else.
Can the sharing link be reset for a particular file / folder?
- GDrive: copy file, then link will change. No way to reset the link. community answer from 2021
- Dropbox: you can reset, set expiration date, etc dropbox docs
NOTE on Dropbox:
You can only delete shared links that you create. If you invite someone to a file or folder with editing access, they can create their own link to share with someone else. You can’t manage those shared links
Software development is not a rocket science, or is it?
VPN considered insecure
general practice for VPN, is to prioritize itself via defining more specific routing rules, which take priority over the default gateway. the attacker, however, can spin up another DHCP server, and use rule 121 to push some new routes to the client. Importantly, if the routes are more specific than the ones defined by the VPN, they will take over, and unencrypted traffic directed to the VPN interface will end up on the attacker’s machine.
the golden standard to avoid this vulnerability is using network namespaces: https://www.wireguard.com/netns/#the-new-namespace-solution
Embouchures
The word embouchure originates from the French bouche - mouth. One of its meanings describes the mouth-work musicians do to extract sounds from brass musical instruments. More popularly, embouchures are those soft parts of the headphones that usually wear out too quickly :)
You are welcome, now you can’t unsee the link between headphones and lips wrapping a musical instrument!
