Every big UK company I have worked for doesn’t own its building. They will typically agree to rent a building for 5-20 years at a fixed rate (longer times if its being purpose built for them) .
So I would expect this is paying out the rest of the rental agreements for a building to escape the building lease.
It is to do with financial reporting and the way asset and operational costs are reported.
Docker swarm was an idea worse than kubernetes, that came out after kubernetes, that isn’t really supported by anyone.
Kubernetes has the concept of a storage layer, you create a volume and can then mount the volume into the docker image. The volume is then accessible to the docker image regardless of where it is running.
There is also a difference between a volume for a deployment and a statefulset, since one is supposed to hold the application state and one is supposed to be transient.
There will always be someone who is beating you in a metric (buying houses, having kids, promotions, pay, relationships, etc…) fixating on it will drive you mad.
Instead you should compare your current status against where you were and appreciate how you are moving forward
As for age
During university my best mate was 27 who dropped out of his final year, grabbed a random job, then went to college to get a BTEC so they could start the degree.
It was similar in my graduate intake, we had a 26 year old who had been a brickie for 5 years before getting a comp sci degree.
The first person I line managed was a junior 15 years older than me, who had a completely different career stream. They had the house, kids, had managed big teams, etc… honestly I learnt tons from them.
The splash screen (boot screen instead of text)used to get me. It provided by an application called ‘Plymouth’.
You used to need to install it and configure grub, however I think if you go into ‘System Settings’ and type ‘Splash’ KDE has an option to install and choose the screen
I wouldn’t use “certified” in this context.
Limiting support of software to specific software configurations makes sense.
Its stuff like Debian might be using Python 3.8 Ubuntu Python 3.9, OpenSuse Python 3.9, etc… Your application might use a Python 3.9 requiring library and act odd on 3.8 but fine on 3.7, etc… so only supporting X distributions let you make the test/QA process sane.
This is also why Docker/Flatpack exist since you can define all of this.
However the normal mix is RHEL/Suse/Ubuntu because those target businesses and your target market will most likely be running one.
I suspect they mean around packaging.
I honestly believe Red Hat has a policy that everything should pull in Gnome. I have had headless RHEL installs and half the CLI tools require Gnome Keyring (even if they don’t deal with secrets or store any). Back in RHEL 7, Kate the KDE based Text Editor pulled in a bunch of GTK dependencies somehow.
Certification is really someone paid to go through a process and so its designed so they pass.
Think about the people you know who are Agile/Cloud/whatever certified and how all it means is they have learnt the basic examples.
Its no different when a business gets certified.
The only reason people care is because they can point to the cert if it all goes wrong
Debian isn’t old == stable, its tested == stable.
Debian has an effective Rolling distribution through testing than can get ahead of Arch.
At some point they freeze the software versions in testing and look for Release Critical and Major bugs. Once they have shaken everything and submitted fixes where possible. It then becomes stable.
The idea is people have tested a set baseline of software and there are no known major bugs.
For the 4-5 releases Debian has released every 2 years (Similar to Ubuntu LTS). Debian tends to align its release with LTS Kernel and Mesa releases so there have been times the latest stable is running newer versions than Ubuntu and the newest software crown switches between Ubuntu LTS and Debian each year.
For some the priority to run software that won’t have major bugs, that is what Debian, Ubuntu LTS and RHEL offer.
Can you elaborate…
I have looked after a few instances of Active Directory and basic user management involved multiple steps through GUI’s clearly written at different times (you would go from a Windows 8 to Windows 95 to Windows XP styled windows, etc…)
I much prefer FreeIPA, if I wanted to modify a user account it was two button clicks. Adding a group and bulk applying was the work of moments. You can setup replicas and for a couple hundred users it uses no resources.
The only advantage I could see related to Exchange Integration as it makes it really easy to setup Sharepoint, Skype & Email.
Sharepoint never gets setup properly and you find people switching to alternatives like Confluence, Github/Gitlab Pages or Media Wiki. So that isn’t an advantage.
Everybody loathes Skype and your asked to setup an alternative (Mattermost, Slack, Zoom, etc…). I am not sure how integrated Teams is.
Which really only leaves Email and I just can see the one off pain of setting up Dovecot as worth the ongoing usability pain of AD’s user control.
You realise Debian is the base distribution?
Ubuntu takes 6 monthly cuts from Debian Testing, adds some in house stuff puts them through QA and performs a release.
Linux Mint is produced by Cinnamon devs, similar to KDE Neon. They take the last Ubuntu LTS, remove many of the in house additions, add the latest Cinnamon desktop and release.
Cinnamon got upstreamed into Debian to make the process easier.
The person is correct in this isn’t a Linux problem, but relates to your experience.
Windows worked by giving everyone full permissions and opening every port. While Microsoft has tried to roll that back the administration effort goes into restricting access.
Linux works on the opposite principle, you have to learn how to grant access to users and expose ports.
You would have to learn this mental switch no matter what Linux task your trying to learn
Dockers guide to setting up a headless docker is copy/paste. You can install Docker Desktop on Linux and the effort is identical to windows. The only missing step is
sudo usermod -aG docker $user
To ensure your user can access the docker host as a local user.
QT is a cross platform UI development framework, its goal is to look native to the platform it operates on. This video by a linux maintainer from 2014 explains its benefits over GTK, its a fun video and I don’t think the issues have really changed.
Most GTK advocates will argue QT is developed by Trolltech and isn’t GPL licensed so could go closed source! This argument seems to ignore open source projects use the Open Source releases of QT and if Trolltech did close source then the last open source would be maintained (much like GTK).
Personally I would avoid Flutter on the grounds its a Google owned library and Google have the attention span of a toddler.
Not helping that assessment is Google let go of the Fuschia team (which Flutter was being developed for) and seems to have let go a lot of Flutter developers.
Personally I hate web frontends as local applications. They integrate poorly on the desktop and often the JS engine has weird memory leaks
