Useful Notes – Ubuntu/Ubuntu Studio 22.04 LTS “Jammy Jellyfish”

I use Ubuntu Studio 22.04 LTS “Jammy Jellyfish” because comes with many-many preinstalled Apps.

Main Things to do after installing Ubuntu Studio 22.04 LTS “Jammy Jellyfish”
========

I have chosen Ubuntu Studio 22.04 LTS because I do Graphic and Video Editing along with my main Programming work…
[Support: Ubuntu Studio 22.04 LTS (Jammy Jellyfish) will be supported for 3-years until April 2025.]
[Note: Ubuntu 22.04 LTS is supported for 5-years.] 
[Direct upgrades to Ubuntu Studio 22.04 from supported versions prior to 21.10 are not supported.]

Main Things To Do:

  1. Get your system ready with updates and repositories. Get familiar with auto-updates [Software & Updates, Software Center]
    sudo apt update && sudo apt upgrade
  2. Install applications of your choice from the software center, mainly Programming IDEs/Editors, because Content Creation Apps are come preinstalled already in Ubuntu Studio.

    [ COMPLETE GUIDE FOR MANY-MANY SOFTWARE Apps INSTALLATION ]
  3. Give your Ubuntu OS a different color [ Settings > Appearance ]
  4. Get familiar with the new screenshot tool. [ When you press the Print Screen button to take the screenshot, it opens the UI and gives you the option to take the screenshot of the selected area, entire screen, or current application window. ]
  5. Know about cleaning your system. The classic apt autoremove command is a good way to remove packages that are not required anymore. https://linuxhint.com/why_apt_get_clean/
    sudo apt autoremove
  6. Master the keyboard shortcuts
    Ctrl + Alt + T: Ubuntu terminal shortcut [instead of opening a terminal use Alt+F2 to run the console]
    Ctrl + Q: Close an application window
    Alt + Tab: Switch between running applications
    Super[Win] + Space: Change input keyboard e.g. En <->Ru
    Ctrl + Alt + arrow: Move between workspaces
    Ctrl + Alt + Del: Log out
    Go to Settings->Devices->Keyboard [for Custom Keyboard Shortcuts]

I major/critical advice from the Source of
========
Ubuntu & Ubuntu Studio – Linux: www.ubuntustudio.org for current-old users of Ubuntu Studio 20.04, about the upgrade to all new Ubuntu Studio 22.04 LTS, NOT TO DO SO… BUT DO INSTEAD A CLEAN INSTALL OF 22.04!!!

Upgrading

Since it’s just out, you may experience some issues, so you might want to wait a bit before upgrading.

Due to the change in the desktop environment that started after the release of 20.04 LTS, direct upgrades from 20.04 LTS are not supported and may only be attempted at-your-own-risk. As with any system-critical operation, back-up your data before attempting any upgrade. The safest upgrade path is a backup of your /home directory and a clean install.

We have had anecdotal reports of successful upgrades from 20.04 LTS (Xfce desktop) to later releases (Plasma desktop), but this will remain at your own risk, and it is highly recommended to wait until 22.04.1 is released in August before attempting such an upgrade.

Instructions for upgrading are included in the release notes.

========

Personally, I did a clean install of Ubuntu Studio 22.04 in VMware Workstation Pro 15 – and would recommend it because this allows you to clean up and start fresh with Ubuntu Studio 22.04 LTS with a new set of applications and a new desktop environment.

The benefits and drawbacks of modern technology

When someone refers for today’s modern technology, surely he refers to the 21st century, Information Age and the Internet as the communication media of the new millennium. Of course this 17 year history of the Internet brought indirectly many significant advances in other Science and Technology fields. Without doubt Internet changed our lives for ever decisively and absolutely.

Today, just with a PC and an internet connection, without additional costs you can send instantly and receive instantly messages(emails) from the other corner of the world just not long before ago you have to await letter to get to recipient in about 7 days if not lost in transit and other so the reply to return to you. Now you can find almost any piece of info with a web browser and chat (eg.Skype), again freely using text, audio or even video.

Another area of technology bring change to us, is Mobile Communications. We are NOT away from the fact each individual, will posses a mobile phone for fun or for business, anywhere he is in the world, anytime. Today exists such services in the mobile world as talking, Small Message Service (SMS), Multimedia Message Service (MMS), or chatting with text, and also accessing the Internet from mobile phone using either wifi access point or 3G cellular internet, and hence you may browse or send email or use some other service of the Internet, anywhere and anytime. Coming is Mobile video calling.

Of course Mobile Communications is very closely related to the Internet, both networks belonging to Electronic Age Revolution of computers in general. This top edge of technology brings us many benefits as well as drawbacks too.

Benefits include fast and more accurate communications and business. Now for example in case of danger eg car accident away from the town, you can use your mobile to call the emergency number immediately and authorities to find automatically using cellular network services, your position on the map you call from, so help come accurately and immediately.

Internet makes us more Socialable people in all steps of life, Social Internet Networks are on rise these days. Now our time is better spent, and use efficiently. Rather use snail mail now we are using email, rather use standard telephone network call now we are using chatting via text, audio, video and file transfer. Almost now any info can get accessed via a web browser using an Internet search engine.

Chatting etc services brings fun, work and education too. Leaning online is a consequence of all these. Now universities provide part or full degrees online. This use of internet technology tools and cost is only from university fees. Also language learning can be taken with technology and resources of the Internet. All these are a click away.

As of security now when you are away, you can watch your office or home via security cameras through the internet. Also when you plan a trip domestic or international, on the Internet you can plan and book everything for it. Also, your Bank can accessed via internet banking with a web browser, so as access accounts, transfer money, order replacements etc.

On the other hand beyond these benefits, Internet Age brings and some subtle drawbacks.

Now when you are online your Internet PC without even know it can get compromised by bad guys, that can stole anything from company data to credit card numbers covering their tracks. The attacks can be done on Internet Servers as well, making services unavailable, may be in emergency sometimes. Banks are on instant danger for example, a bad guy may change account data and more.

Of course many anti-criminal tools exist like anti-virus tools, anti-malware, anti-spyware and so on, that must be considered by any Internet user.

Of course as internet makes us smarter, so does smarter the street thieves too. So we must be careful in using all of our possessions, and especially credit cards in front of cameras in all steps of life. Thieves continue to discover new ways, to draw your attention, and so on and so forth.

Finally I think new technology has brought many advantages and drawbacks. People behind the internet and technology think well before they create it, so as to advance our lives and NOT to degrade it. So in my opinion I believe, modern technology has brought more goods to us, rather than drawbacks. In case of drawbacks exist always an anti solution. Technology is going to advance, but as we proceed this is going more slowly, and it will stay good for us, in all its way.
