The documentation about default confg covers all the parameters’ meanings and can be used as reference for that! detectron2.config — detectron2 0.5 documentation
And me dreaming up cfg.MODEL.CHECKPOINT_PERIOD is exactly what they wanted to avoid by disallowing the creation of new keys.
Highlights:
# Number of images per batch across all machines. This is also the number
# of training images per step (i.e. per iteration).

For the second time, discovered that Telegram Cache takes 40gb of disk space.
In the phone’s own menus related to disk space, this was shown as “Pictures” taking 40gb, not the Telegram app and its cache. But this info is exposed through Telegram’s own menus.
Who knew you could combine commands! This is how you start tracking tag1,tag2 starting from the end of the previous span:

TL;DR:
duc index ~/ --fs-exclude fuse.sshfs
duc is about disk space, before running it the index should be built/updated. Usually similar to duc index ~/.
If I have a sshfs mounted somewhere, the process never ends as it tries to index the folder where it’s mounted.
Found some solutions:
duc index ~/ --fs-exclude fuse.sshfs
ext3,ext4./etc/fstab didn’t have the sshfs filesystem, but mount called it fuse.sshfs and this worked!duc index ~/ -e "*somefilename*"
*folder\/file* etc).Bonus: -p shows progress during indexing.
Now I have a new alias in ~/.zshrc:
ducindex() {
duc index "$1" -p --fs-exclude fuse.sshfs
}
cdd CLI alias for CD-ing to directory containing a fileI copypaste a lot the locations of the files from pycharm/intellij to run them from CLI or something similar. Easiest way, because they are focused and I don’t need to focus on the files/project view for that. I can’t find an Action in pycharm/intellij to copypaste only the directory.
Yet another alias for today:
cdd() {
$(dirname "$1")
}
dirname gives the directory, dirname .. | cd and dirname ... | xargs cd don’t work (TODO - why?), so I’m using the zsh thing about “cd to the directory if it’s in a command by itself”.
Now cdd /home/me/wahtever/test.py takes me to /home/me/whatever/ which will saved tens of seconds per year!

I often do <CR>ddkkp or d$kp as a reverse-enter, moving what’s to the right of the cursor on the line above the current one. I’m sure something like this already exists in vim.
Detectron’s Yacs has a github repo with documentation and examples, much better than detectron’s own: rbgirshick/yacs: YACS – Yet Another Configuration System
This works:
comp_cfg.set_new_allowed(True)
comp_cfg['key'] = 'value'
Interesting bit about why it’s not like this by default:
We typically don’t use this so that typo in config file can be noticed. 2
Additionally, this is set per leaf, not per config - you can allow adding stuff to the root but not to its existing children.
And, still, even with comp_cfg.set_new_allowed(True), why can’t I merge_from_list etc. for non-existing keys? (TODO)
log.txt is nice and colorful on CLI, I don’t remember how to let vim interpret the CLI colors but less log.txt works magnificently.

If you are inside a screen, and need to write the entire contents to a file (not just the ones currently visible), this will work:
<C-a> :hardcopy -h <filename>.
In the context of a raised hand in google Hangouts meeting: “Do you have a question or an opinion?” (heard at work)
…TIL at work in a remote meeting. Makes the window with the code full-screen, hides the other windows, and increases the font size. Neat!
Yet another chapter of “python stdlib implementing most things I need better than me”, to create an infinite iterator itertools.count() is better than stuff like iter(range(100500)) (from AA’s comment in a PR)
Couldn’t use ethernet because the device was ’not managed’ according to nm-applet.
Neither
sudo nmcli dev set enp0s31f6 managed yes
nor changing managed=false to managed=true in /etc/NetworkManager/NetworkManager.conf helped (after the usual service restarts).
But creating an this empty file did:
sudo touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf
Memory lapse on my side, I thought tempfile.gettempdir() returned a random temporary directory I can use. Nope, it returns the absolute address of /tmp or its equivalent on that platform.
I was thinking about tempfile.gettempdir(). There are also tempfile.TemporaryDirectory(), which gets automatically removed after the context ends or the object is deleted.
It’s the kind of things I’m afraid of in shell scripts, where manually deleting a temporary directory could remove more than needed.
As usual, the python docu on topic 1 is a good thing to read.
There’s no way to remove a directory with all its contents recursively using pathlib. 2
pathlib.rmdir() removes empty directories, pathlib.unlink() removes files.
The way to do this is external libs, a la shutil.rmtree().
Very very weird design decision, as removing stuff is in no way an uncommon operation.
But a recursive pathlib solution exists, from same StackOverflow answer:
from pathlib import Path
def rmdir(directory):
directory = Path(directory)
for item in directory.iterdir():
if item.is_dir():
rmdir(item)
else:
item.unlink()
directory.rmdir()
rmdir(Path("dir/"))

When coding in a plane and then on a bus did some slight changes, some are useful:
font_family FiraCode-Bold
font_size 12.0
If I’ll be on the road more often, I’ll create this as a mode or something - bold bigger text, different IDE colorschemes, etc.

Was redesigning my website, looked if there’s a smarter way to color links based on whether they are internal/external than manually adding classes to them. Well there is: Attribute selectors - CSS: Cascading Style Sheets | MDN
Attributes can be parsed based on prefixes, suffixes, containing something, belonging to a predefined list etc.
