cat github.com.pem | sudo tee -a /etc/ssl/certs/ca-certificates.crt

git config --global http."https://github.com.pem/".sslCAInfo ~/github.com.pem

git config --global http.sslverify false

export GIT_SSL_NO_VERIFY=true

Then this error is gone:

Fyne on Windows 7

 For a cheap, obsolete environment I got a problem, fyne ui does not see my opengl. I remembered, the same problem appears for WFP, it also does not find hardfare graphics acceleration, but it is possible to run UI in software render mode. So do for fyne

after build app, copy software Mesa3D opengl.dll to folder with binaries, then it works.

This fix these crashes on start:

copilot

 1. For first classes it did not realize context properly and it is good because he operate only names.

2. After read some logic that I use for app he can think logically already

3. For math equations he generateright code.

4. He start to know relations in object oriented model in time I wrote half of class decomposition

5. Lates class in screenshot he implemented without any moderation by his name. He dot the cnowledge about context and models to realize full group of rules and logic.

Despite a lot of jokes copilot from Microsoft works great for people that think.

Kafka on Ubuntu 20.04

I used this post:

https://www.digitalocean.com/community/tutorials/how-to-install-apache-kafka-on-ubuntu-20-04

but I downloaded latest Kafka for me:

 https://downloads.apache.org/kafka/3.1.0/

Then I started to install zookeeper with simple article, but service was not started:

https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-an-apache-zookeeper-cluster-on-ubuntu-18-04

Then I found this Knowledge Base with script:

https://kb.altinity.com/altinity-kb-setup-and-maintenance/altinity-kb-zookeeper/install_ubuntu/

Screept looks good, but zookiper command was not waitlisted, a fix is from answer:

https://stackoverflow.com/questions/62667788/how-do-i-initialize-the-whitelist-for-apache-zookeeper

A configuration should be in sub folder:

cat <<EOF | sudo tee /opt/zookeeper/zookeeper.properties

initLimit=20

syncLimit=10

maxSessionTimeout=60000000

maxClientCnxns=2000

preAllocSize=131072

snapCount=3000000

dataDir=/var/lib/zookeeper/data

dataLogDir=/var/lib/zookeeper/logs # use low-latency disk!

clientPort=2181

#clientPortAddress=nthk-zoo1.localdomain

autopurge.snapRetainCount=10

autopurge.purgeInterval=1

4lw.commands.whitelist=*

EOF

The latest for enable Kafka is disable auto generated cluster to use simple mode:
