What is the difference between these two packages?
pip3 install pytesseract
pip3 install tesseract
pip3 install pytesseract gets me this package
Python-tesseract is a python wrapper for google's Tesseract-OCR
pip install tesseract gets me this package
Tesselation based Recovery of Amorphous halo Concentrations. The TesseRACt package is designed to compute concentrations of simulated dark matter halos from volume info for particles generated using Voronoi tesselation.
Both are OCR wrappers for Python; however, pytesseract is based on Googles OCR API and tesseract isn't. I would suggest using pytesseract based on the fact that it will be maintained better, but with that being said, try them both out and use whichever works better for you.

I am trying to hook up my Raspberry Pi Zero W, running Raspberry Pi OS Lite, to a Raspberry Pi NoIR Camera Module V2. After running these commands:
sudo apt update
sudo apt upgrade
and enabling the camera in the raspi-config menu and rebooting per the Raspberry Pi documentation, when I run the command raspistill -v -o test.jpg according to the Raspbery {Pi documentation, I get the below error.
-bash: raspistill: command not found
The documentation says:
This probably means your update/upgrade failed in some way.
I tried it again. I ran update, upgrade commands, rebooted and enabled the camera in the raspi-config multiple times with no change in outcome.
raspistill has been replaced by libcamera.

I wonder separately install KSQLdb amid Kafka when Kafka was installed from officail distributive?
There is no standalone package
The Docker image mentioned in the docs is built from the source code on Github, then configures the ksql-server.properties file and runs ksql-server-start, which is what you would need to do as well, starting with mvn package of the source, then finding the appropriate rest-server JAR files
You can also chime in on this Github issue with the same question

hi there is no linux device driver library available on my LInux OS in the folder /usr/src/kernels.Can I add or load it ,if yes how to dothat .i need it for device driver develoment.
thanks
You need the kernel headers to compile modules/drivers.
On Fedora, you can use the following command
yum install kernel-devel
On Ubuntu, you can use the following command
sudo aptitude install linux-headers-`uname -r`
Or you can also get the entire kernel source/headers from kernel.org

I'm maintaining a simple web site written in Perl in my copious free time, and I don't want do my coding on the live website any more, instead checking if the changes work on a local machine first.
As far as I can tell, the web site runs on apache.
Should I install apache on my local machine, or are there simpler (but well documented!) options more suited to a development box?
Related question: How can I run Perl on web servers? , but seems to be talking about a production box, not a development box.
XAMPP is an excellent package for precisely this purpose. It includes Apache, MySQL, PHP, Perl, and other tools, all pre-configured to run on your local machine. I use it for WordPress, but I expect that it would be equally good for Perl CGI development.
I use it on Windows. It is also available for Linux and Mac.
Hat tip to Kenosis, who mentioned XAMPP first. I didn't see that at the time.
