The most useful git commands | orga.cat

Posted by jpluimers on 2020/07/22

The most advanced commands are towards the tail of [WayBack] The most useful git commands | orga.cat

Here there are some examples of git commands that I use often.

They include:

Get the git root directory

git rev-parse --show-toplevel

Source: http://stackoverflow.com/q/957928/1391963

See closest tags

git describe --tags `git rev-list --tags --max-count=1`

Source: http://stackoverflow.com/q/1404796/1391963. See also git-describe.

See recently used branches (i.e. branches ordered by most recent commit)

git for-each-ref --sort=-committerdate refs/heads/ | head

Source: http://stackoverflow.com/q/5188320/1391963

Which means I need to look into at least these:

GitHub – adaloveless/commonx: Delphi/Object Pascal Classes and Tools for just about everything and everyone.

Warning: I posted this without doing a proper copyright check on the linked github repository, and it looks like this library heavily copies code from copyrighted materials.

So better not use them, for one because they contain copyrighted material, and also because the copyrighted units are not current.

Git install tip for Windows installations: “”

Posted by jpluimers on 2020/07/21

When installing Git on Windows, you might want to change the default HTTPS transport back-end setting into “Use the Windows Secure Channel library” as it will use the Windows Certificate Stores for certificate validation. For Windows users, this allows for a more natural way to configure additional Root CS certificates (for instance the ones coming from Active Directory Domain Services).

If you later want to change this, then you can either re-run the installer, or perform these commands (based on the installer source):

To select the OpenSSL library:

config --system http.sslBackend openssl

To select the Windows Secure Channel library:

config --system http.sslBackend schannel

I do need to check out other ways of installing it (more on that in [WayBack] 5 Ways to Install Git on Windows · James Sturtevant), but for now I’m using the regular installer.

At first time install (subsequent installs will re-use the first-time install location without a way to overwrite them):

  • If you run that “As Administrator”, then it will install for all users (64-bit in C:\Program Files\Git, 32-bit in C:\Program Files (x86)\Git)
  • Otherwise in %LOCALAPPDATA%\Programs\Git which usually is in C:\Users\<username>\AppData\Local\Programs\Git).

Note that the actually executables are inside a bin subdirectory of the installation path.

Operant Conditioning by Software Bugs – Embedded in Academia

Posted by jpluimers on 2020/07/21

Good to remember both these:

[WayBack] Operant Conditioning by Software Bugs – Embedded in Academia which means when using a system, you subconsciously start behaving around it’s issues. This also happens when you the software you wrote the software for such a system: you hardly test the things that you broke.

The magic SysReq key on Linux systems running on PC-hardware allows you to sync/mount read-only/shutdown a system by keyboard (and many more options – see the Wikipedia list below). Do not forget to enable this as it is disabled by default. And remember that many laptops forego the SysReq key (as do Mac systems).

The order while holding Alt-SysReq down is S,U,B…

google chrome – How to hide the bookmark bar? – Super User

Posted by jpluimers on 2020/07/20

So I wondered why on some tabs, the bookmark bar would never disappear:

Chrome’s default new tab page (NTP) always shows a bookmark bar, even if you turn it off for other pages. You can however install browser extensions which replace the NTP, and the replacements do not automatically get the bookmarks bar (but can with some extra programming).

So for instance Google’s Earth View extension does not show bookmarks, whereas Pinterest’s now does.

Thanks deltab for answering this at [WayBack] google chrome – How to hide the bookmark bar? – Super User

Eject USB drives / eject command – Unix & Linux Stack Exchange

Posted by jpluimers on 2020/07/20

I always thought than an umount /dev/sdX# for all partitions on /dev/sdX was enough for USB devices to be ejected, but there are three commands that (on most systems) actually power down USB drives (or USB to SD card adapters):

  • udisks --detach /dev/sdX (requires the udisks package which is obsolete)
  • eject /dev/sdX seems not to be enough on some systems; it is part of the util-linux package
  • udisksctl power-off -b /dev/sdX is equivalent to the udisks command; it is part of the udisks2 package.

These will ensure that the disk is not part of the fdisk --list output any more.

The opposite of these is sg_start, which is from the sg3_utils package.

On MacOS, you can use  diskutil eject /Volumes/<LABEL> (source: answer by efesaid on [WayBack] Eject USB drives / eject command – Unix & Linux Stack Exchange)

Colorectal Cancer: Stages | Cancer.Net

Posted by jpluimers on 2020/07/18

For my link archive:

These explain the below stagings.

  • cT3N1Mx:
    • c: stage determined before treatment
    • T3: tumor invades through the muscularis propria into the pericolorectal tissues
    • N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
    • Mx: could not be evaluated for distant metastasis
  •  cT3bN1Mx:
    • c: stage determined before treatment
    • T3b: 1-5 mm extension beyond muscularis propria
    • N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
    • Mx: could not be evaluated for distant metastasis
  •  cT3N1M0:
    • c: stage determined before treatment
    • T3: tumor invades through the muscularis propria into the pericolorectal tissues
    • N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
    • M0: no distant metastasis
  • cT3bN1M0:
    • c: stage determined before treatment
    • T3b: 1-5 mm extension beyond muscularis propria
    • N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
    • M0: no distant metastasis
  • cT3bN1:
    • c: stage determined before treatment
    • T3b: 1-5 mm extension beyond muscularis propria
    • N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
  • ypT2N1a:
    • yp: stage determined after chemotherapy (y) and histopathologic (p), in this case also after surgeries of both tumor and metastases
    • T2: size of tumor
    • N1a: regional lymph node metastasis present in 1 lymph node
    • No M means no metastasis detectable
