QT 5.15 Commercial-only LTS phase starts: Closing the 5.15 branch(es) on 5th January

With Qt 6.0.0 released and the first patch release (Qt 6.0.1) coming soon, it is time to enter the commercial-only LTS phase for Qt 5.15 LTS. All the existing 5.15 branches remain publicly visible, but they are closed for new commits (and cherry-picks). Exception being the Qt WebEngine (and the deprecated Qt Script), which have a 3rd party LGPL dependency. Closing happens tomorrow, 5th January 2021. After this the cherry-picks go to another repository that will be available only for the commercial license holders. We will arrange repository access to the commercial license holders, so in addition to the official releases it is possible to use the repositories. Instructions about this will be available to commercial license holders during next week, after we have completed the license change and other preparations. First commercial-only Qt 5.15.3 LTS patch release is planned to be released in February.

What Windows does better that we Linux community should learn from?

I love the flexibility and customisabilty of Linux distros, and many advantages GNU/Linux distributions have over Windows.

But I would like to know what are some of the things we should learn from the Windows OS (or their community)?

Is there anything Linux/BSD related that makes you feel nostalgic about?

Browsing on reddit, somehow I bumped into this Plan 9 screenshot and man, it does look clunky, but I kinda miss those geeky times.

I'm all in for practicality and ease of use.

But, at the same time, I kinda miss that sort of adventure that was getting on the inner parts of Linux and spend days reading documentation, looking at every denoscription in the Kernel menuconfig and getting to know, for the first time, that immense gallery of software technology that was available for free, even for the shittiest machine a low end computer could run.

Also, getting X to run, starting with fluxbox, using Xfce for a while and ending in the Gnome 2 desktop, which, contrary to Gnome3, was made to be fully customizable.

I wouldn't do it again, but it was a fun ride.

Iptables: table->chain relation (are they using the correct terms in the manual? )

The man page says that the tables (filter/nat/mangle/...) contain/consist-of/have/provide their respective chains. So as someone new to iptables i would suspect that the kernel on the outer loop processes the tables (filter, nat, mangle... ) and on the inner loop it would process their respective exclusively owned chains (INPUT, PREROUTING, FORWARD,...)

But this seems stupid and is obviously not the case when i -j TRACE a packet. It goes i.e from

raw:PREROUTING:
mangle:PREROUTING:
nat:PREROUTING
mangle:FORWARD
filter:FORWARD

That confuses me very much. Would'nt you better speak it the opposite way: A Chain contains/processes the following List of Tables... Also the manual should list in which order they are processed.

Is Proprietary Software more secure than Open Source?

I’ve seen an argument lately that goes like this:

Open source software is more secure because everyone can see if there’s a risk to the users privacy.

But Proprietary software is more secure because it’s more locked down and the only people editing it are the creators of it.

Of course this doesn’t account for a majority of things like, users not contributing or checking the source code of software. Or companies making insecure software on purpose. But I just want to know what you all think, and which side to you fall towards?

DISCLAIMER: THIS IS NOT A “ONE WAY OR THE OTHER” SCENARIO ITS SIMPLY A SURVEY AND A DISCUSSION.

What's the Linux equivalent of rooting Android?

Actually, I'm confused if Android a Linux distribution. I had many phones, and unlocked bootloader and rooted those devices. But when I'm using Ubuntu or similar, what's the equivalent of Android's unlocking bootloader and rooting? Are there similar on Ubuntu?

What's your reason prefer using independent linux distro (like Debian, Fedora, Arch & OpenSUSE) rather than their derivatives one (like Ubuntu, Korora, Manjaro & GeckoLinux)?

I asked this to my friend and he said independent Linux distro offers very vanilla DE experience while derivatives from that distro already modified the DE to the point it'll break the DE if you tried to change the themes & the icons, but I'm still not impressed. Is there any main advantage other than that?

What are your thoughts on Fair-code licenses?

This is somewhat unrelated to r/Linux but it's probably the largest community which have an opinion on licenses.

At first glance Fair-code seems like a great strategy to make money with open software for independent or small groups of devs. What are your thoughts on pros/cons?


Edit:
For those that don't know Fair-code adds a "common clause" to an existing license stating that you can't sell the software.

"Without limiting other conditions in the License, the grant of rights under the License will not include, and the License does not grant to you, the right to Sell the Software...."

Anybody here using Photoshop with wine?

Hey there :

1) which version of wine and photoshop do you use?
2) i am using cs5 with wine 5.2 - does the "platinum" status apply here or was that for older wine versions?
3) did you have the same problem as me, that wine would use the intel graphic card instead of the nvidia one? how did you solve it?

What do you feel is missing in the Linux kernel?

Linux kernel is far from perfect. Like any other project does. Many here may not be kernel devs, like myself. I personally feel better audio support is missing from the Linux kernel. What we have is good, but could be much better.

But, what do you feel is missing from the Linux kernel?

Moving root from HDD to SSD

I have a laptop with 256GB SSD and 1TB HDD. The SSD only contains windows partition and the HDD contains both windows as well as Linux partition (root+home).

Since I do not use windows much, I am planning to give transfer my Linux root partition to SSD. I need help with how can I transfer the whole root partition to SSD without reinstalling it as I am still not completely sure about how I can do that (some guide, tutorial, etc). Also, since it is my daily driver and I will be using it a lot for the next few days, I do not like to fresh setup everything currently.

FWIW:-

OS - Arch Linux
Root and home partition are separate so there will not be any problem with the home partition even if something goes wrong with root (but still does not want anything to happen)

PS - I am not sure if anything else is needed but please tell me if it is

PSA: For those of you that, like me, have a newer Lenovo laptop and the touchpad and brightness controls weren't working, they have been fixed on Kernel 5.11, guide below.

I'm posting this because I am not a technical user and it's taken me a long time to figure out how to update the kernel (sad I know). So for others like me I wanted to post this, hope that's ok.

For any noobs like me that are on Ubuntu this is the guide that I followed to upgrade to kernel 5.11 and everything works perfectly for me, both the touchpad and the brightness controls. (I have a new Lenovo Legion and until recently the touchpad and brightness controls weren't working)

Upgrade kernel by going to the terminal and copying and pasting these instructions:

Change current directory to /tmp
cd /tmp

Download the latest mainline kernel from 5.11.x branch by copying and pasting this:

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11-rc2/amd64/linux-headers-5.11.0-051100rc2_5.11.0-051100rc2.202101032030_all.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11-rc2/amd64/linux-headers-5.11.0-051100rc2-generic_5.11.0-051100rc2.202101032030_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11-rc2/amd64/linux-image-unsigned-5.11.0-051100rc2-generic_5.11.0-051100rc2.202101032030_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11-rc2/amd64/linux-modules-5.11.0-051100rc2-generic_5.11.0-051100rc2.202101032030_amd64.deb

Install new kernel
sudo dpkg -i *.deb

Reboot the system
sudo shutdown -r now

Update packages list
sudo apt-get update

Upgrade packages
sudo apt-get upgrade

Reboot the system if needed
sudo shutdown -r now

Check the OS distro
lsb_release -a

Check kernel version
uname -r

That's it, now you should be running on the Linux Kernel 5.11rc2

Thanks to everyone for their hard work over on the launchpad thread (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1887190?comments=all) sorry for posting this noob guide here but it took me weeks to figure out an easy way to do it (patching was beyond my abilities). Hope this helps someone!

LTS versions of Qt going closed-source

The Qt Company are making LTS releases commercial only and thus closed-source. "The problem is that these releases are in effect no longer maintained. If there is a security issue, or a fix needed to support some change in one of the target operating systems, open-source users will not get that fix other than in the not-ready version 6.0."

Did you know? Tor and firejail

As you already know, Tor is a browser that helps you stay anonymous on the internet.

Whenever you download a file, Tor warns you about opening the file after it is downloaded.( you should open files offline if they come from unknown/untrusted sources)

The best way is to open the file in a VM. But there is also firejail (sandboxing) that allows you to open files as safe as in a VM with right parameters.

Example : reading pdf's from unknown/untrusted sources in okular offline

firejail --net=none --seccomp okular

You can also use it to sandbox other apps like firefox/tor for more security

firejail firefox

It is not much, but i thought you should know this.

Further reading :

In cmd : man firejail
