gradle

• https://www.baeldung.com/gradle
• In a typical Gradle project, each subproject or module usually has its own build.gradle file. Here's a general overview:

1. Root Project: The root directory of your project contains a build.gradle file that defines the overall build configuration.
2. Subprojects/Modules: Each subproject or module within the root project has its own build.gradle file. This allows you to define specific build configurations for each subproject

Ubuntu 24 display problem

 I just installed a new Ubuntu 24. When I run file manager, I lack pieces of the display like text and icons. Most of them appear with a mouse over. 

A work around is to select the x.org x server as shown below. But once you do that, you cannot suspend Ubuntu anymore

Note: after doing the instruction here below, I got back my correct display (but still cannot awake successfully after suspend)

    sudo apt-get update

    sudo dpkg --configure -a

    sudo apt-get install update-manager-core

Python string format / print

a) using  str.format():

>>> print('We are the {} who say "{}!"'.format('knights', 'Ni'))
We are the knights who say "Ni!"

The brackets and characters within them (called format fields) are replaced with the objects passed into the str.format() method. A number in the brackets refers to the position of the object passed into the str.format() method.

>>> print('{1} and {0}'.format('spam', 'eggs'))
eggs and spam

>>> print('This {food} is {adjective}.'.format(food='jam', adjective='absolutely horrible'))
This spam is absolutely horrible.
Positional and keyword arguments can be arbitrarily combined:

>>> print('The story of {0}, {1}, and {other}.'.format('Bill', 'Manfred', other='Georg'))
The story of Bill, Manfred, and Georg.

b) using f-strings    (need Python 3.6)

toto = 10
titi = 15

print(f' toto = {toto}', f' titi = {titi}')

print() can take 255 parameters. When using '+' is a way to have a single parameter is used.

c) using % format (old school, strong limitations)

_________________ from copilot about f-string versus format print

Both f-strings and the `format()` method in Python are used for string formatting, but they have some differences.

f-strings (formatted string literals) were introduced in Python 3.6. They are prefixed with 'f' and are a new and improved way to format strings in Python. They are concise, easy to read, and less prone to error than other formatting methods. 

The `format()` method is available in both Python 2 and 3. It's more verbose than f-strings, but it's more flexible and can do a few things that f-strings can't, like dynamic formatting. Here's an example:

>>> percentage = 0.23456789
>>> '{:2.2%}'.format(percentage)
'23.46%'

In general, if you're using Python 3.6 or later, f-strings are the recommended way to format strings due to their simplicity and efficiency. However, if you need to support older versions of Python or require more complex formatting, you might want to use the `format()` method.

print" is a function in Python3 (was a statement in Python2)

https://docs.python.org/3/tutorial/inputoutput.html

def print(self, *args, sep=' ', end='\n', file=None)

jbd2 causing a lot of disk access

Symptom: jbd2 very active in iotop:

  221 be/3 root        0.00 B/s   60.87 K/s  0.00 % 38.90 % [jbd2/sda2-8]

This can happen if you changed a lot of files on your hard disk, but activity will go lower over time.

To disable the updatedb cron that uses jbd2 also, you can do:

sudo chmod -x /etc/cron.daily/mlocate

You can also change the commit frequency in /etc/fstab (but jbd2 will happen anyway, but less frequently)

 root@arau3:~# more /etc/fstab 

# /etc/fstab: static file system information.

#

# Use 'blkid' to print the universally unique identifier for a

# device; this may be used with UUID= as a more robust way to name devices

# that works even if disks are added and removed. See fstab(5).

#

# <file system> <mount point>   <type>  <options>       <dump>  <pass>

atom editor

My packages:

    - pretty-json

Insert a carriage return:

    - switch to regexp mode and put \n in the "replace" zone

Select a rectangle

  - If you want to select a rectangular region in atom all you have to do is first set the horizontal dimension by selecting some text, then set the vertical dimension by holding CTL-SHIFT and then pressing the up or down arrow. 

Alternatively you can do this the other way around and set the vertical dimension first with CTL-SHIFT, then let go of CTL but keep holding SHIFT and then use the right or left arrow to select the horizontal dimension.

Re-install Windows 10 on Asus

Asus R457UV

re-installer Windows via clé USB.  (disque dur remplacé par exemple). Besoin du user bios admin. Si un user admin bios a deja ete installé et que l'on ne se souvient pas du mot de passe, il faut reprogrammer l"EEPROM sur la carte mere sur ce modele.

https://www.forum-des-portables-asus.fr/forums/resources/changement-et-ou-reprogrammation-de-leeprom.208/

La clé Windows est en dur sur la carte mere Asus. Elle n'est plus fournie ni à l'utilisateur ni au constructeur. C'est la politique de Windows pour éviter les fraudes.

Télécharger l’image ISO de Windows 10 depuis le lien ci-dessous mais il faut choisir la langue, la version et l’architecture qui correspondent au système préinstallé, c’est-à-dire, si vous possédez un Windows 10 Home 64bits français, il faut sélectionner Français au niveau du champ « langue », Windows 10 Home dans le champ « Version » et 64 bits dans « architecture »

Télécharger Windows 10

Télécharger Windows 10

Pour bouter sur la clé USB, 

1. Bios / Security / Secure Boot Control = Disabled
2. Bios / Boot / Fast Boot = Disabled
3. Bios / Boot / Launch CSM = Enabled
4. F10 + Yes
5. Bios / Boot / Boot Option Priority = Clé USB
6. F10 + Yes

https://www.asus.com/in/support/FAQ/1013017/

[concernant ce paragraphe, je n'ai pas pu remettre le BIOS comme avant. Je suis resté en Bios "CSM enabled". Quand je passe en CSM disabled, le disque dur n'est plus detecté]

L'ordinateur va booter sur la clé USB. Une fois l'installation du système (Windows 10) est terminée, Il faut revenir dans le BIOS et remettre toutes les options changées plus haut comme au début et surtout Bios / Boot / Boot Option Priority = Windows Boot manager et F10 + Yes, l'ordinateur va démarrer sur le système.

A la fin de l'installation, le système va récupérer automatiquement la clé lors de la première connexion internet pour la récupération des différentes mises à jour Windows.

Multiple git accounts

Using multiple ssh keys for multiple gits:

https://gist.github.com/jexchan/2351996

Add the ssh keys on github

Some possible "git config --list" options are "--local" and "--global"
If you don't specify --global, it takes the local config by default.

To display the actual  “git config” do:
git config --list

git config user.name

git config user.email

Before you commit, you need to be sure you are using the correct one.
You can set it by doing:

git config user.name "abc"

git config user.email "abc@abc.com"

The local config will be saved in .git/config
The global config is saved in ~/.gitconfig

"url" must be a git@something  in .git/config, should not be https. If it is https, use:

“git remote set-url origin git@github.com:me/gg-linux.git”

It will change your .git/config

_______ git clone

to display default config:

• git config --global --list

Even if the keys are on github, you may want to use a specific name/email

• You can use
• git clone XX -c user.name=toto -c user.email=toto@toto.com (this will set .git/config)
• or
• git config --global user.name "xxx"
• git config --global user.mail "xxx"
• git clone git@github.com:youruser/myj-gh     (need ssh keys)

______________ Just using ~/.ssh$ more config 

Host *.internal 10.*

identityfile ~/.ssh/id_rsa

Host *github.com

identityfile ~/.ssh/id_rsa_github

Google services empty the battery

Android is up to date.
Google Services is making continuous network access and empty the battery. It stops when network is disabled.

solution: register for the Google Services beta program. That's the only way to update/change Google Services
