codimd-index: maintain a global index for codimd pages.

We have a team codimd and it is wonderful. We have CMD_ALLOW_FREEURL=true so that users can create alias'd (named) pages.

Users can't see each others pages though, unless they know to look for them (codimd/#975).

This is just a "manually updated" script to generate a simple index page. It'd be wonderful if codimd/#103 was fixed, then we could generate a table and let user sort.

To run it, you need pyscopg2 (apt install python3-psycopg2).

yaml anchors demo

yaml anchors are:

• useful
• confusing
• hard to google for

yaml can be quite hard to read and see if it is valid.

I use 'yaml-dump' script here to just load a file and dump it as json to more easily see what it loads as.

bash version of lxc-usernsexec

I was in need of something like lxc-usernsexec but ran into some issues lxc/#3420 using it (possibly user error). I put together a test case testing what I thought were valid invocations of lxc-usernsexec. That is here as test-usernsexec.

I looked at the implementation and came up with the bash version here ias 'usernsexec'. My version passes the test case.

My version doesn't get tty's for the executed command.

little endian conversion

I was working on gpt package in go and I didn't realize that the author had handled conversion to little endian when writing header.

I was under the impression that I had to create the header with the little endian value.

For example, the Size of a standard header is 92 bytes.

slow cirros downloads over ipv4/http

Problem

download.cirros-cloud.net is currently experiencing extremely long load times over HTTP and ipv4.

Notes about the problem:

• limited to http traffic over ipv4. The problem does not occur over HTTPS or over ipv6.
• occurs on all files small or large. download.cirros-cloud.net/version/devel is only 6 bytes long. Users reported the issue on images such as 0.4.0/cirros-0.4.0-x86_64-uec.tar.gz which is ~ 11MiB.
• It has gone away between 11:00 AM PST (-0700) and then starts up
