lf: Go-base terminal file manager alternative to ranger

Used ranger all the years but struggled when installing it to a new machine these days: couldn't get previews to work, found the config messy and lots of defaults not really sensible. Just discovered Go-based lf by accident and what can I say... it works out of the box, perfect defaults and it's fast. Wondering why it's not more popular.

Finally a decent Linux Firewall (GUI) - Portmaster (alpha)

https://safing.io/portmaster/

Probably an unpopular opinion, but not everyone is a command line pro, able to dive into iptaple and ntf. I certainly have always struggled with FWs on linux despite using it for 15 years and always wondered why there are no simple solution like on windows and android. What I mean by this is, id like a popup as soon as a process tries to established a connection, giving me the option to block or allow this. The alpha is working semi-stable for me on debian based systems.

Doubt Using graphics for anything?

Hi!
I have always had the doubt if I run any software with a dedicated Nvidia card in laptop, Will I get better performance?
For example if I run Firefox or Matlab with it, will I get better performance? This is assuming that I managed to make the graphics work properly with the drivers. (Debian stable, gnome)

What is the most effective way to support the various Linux-based projects?

Dear community,

I know the Linux foundation exists. I know most of the distributions have companies behind. Every project (app) can receive donations.

With this being said, what is the most effective way of supporting the project financially as a whole? How are all the previous parts connected and which is in your opinion the weakest link (therefore to be more supported)?

I am a relatively new user, I apologise for the possible misuse of terms.

Experiences using Interlink Mail & News with Enigmail?

I can't keep fighting against Thunderbird updates. I need Enigmail as Thunderbird's new native PGP doesn't do what I need it to (encrypt list emails: "per-recipient rules") and doesn't look set to for a very long time. From Enigmail's site it looks like Interlink is the only Linux option right now but there is little information about it online.

Anyone had recent experiences?

Or can think of another non-Thunderbird solution for me?

ffmpeg vs SD capture card

I'm trying to set up an SD capture card, and figure out the right flags to watch VHS tapes through ffplay. I'm able to use ffplay to play back audio and video separately with:

$ ffplay -f alsa -i hw:CARD=CX23885:DEV=0

and

$ ffplay -f v4l2 -i 0

but I can't for the life of me figure out the command line flags to read from both devices at once. Does anyone have any tips?

Linux Engineer job candidates: Am I to picky with my questions ?

Hello everyone

I'm in a fight at my job with various persons (HR, other departments, Boss etc.) regarding job interview questions for a position as a Linux Engineer (SENIOR position).

I deal almost daily with environments from small to gigantic (12 - 36k+ Server/Hosts). What I mainly do is implement a monitoring solution, patching, troubleshooting, noscripting (Ansible + BASH), develop new monitoring plugins, maintain and be responsible for MySQL/MariaDB productive server, various web server and application server, security auditing, tshoot network problems etc. etc. etc.My job is typical for a consult --> many customers !

Almost 75% is direct work with Linux, 10 % organizational tasks and 15 % I deal with physical devices like 19" Servers, SAN's, NAS, Firewalls, Switches and various other stuff.

However, to get a new team member we try to hire a new Linux Engineer (not a junior).Each candidate must solve some (IMHO) base questions regarding linux and networking...specially those people who give me a feeling that they constantly lie in their CV. ...I struggle mainly with candidates who describe themselves as highly experienced gurus who can do everything on Linux and also can code in BASH, Python, PHP etc. but in reality know NOTHING (not even an if statement in whatever language) ...

Among my 15 questions (which our apprentice can solve easily) are 2 subnetting questions...

I need some basic skills in networking...like understanding vlans, tshoot IP address issues etc.I do not ask anything about vlans...I do not ask anything deep...I just want to know if a person can read a subnet mask and can (without help of any online app) calculate the ID, BC and the valid amount of hosts...I only use simple subnets like /30 or /27.

From 7 candidates, NO ONE were able to solve them (among almost everything else like SGID, what is the app behind port 3306 (people who claim they are MySQL aces)...many candidates pretend they are LPIC-1 or LPIC-2 (both do have network topics on the curriculum).

Let me show you guys my 2 subnetting q's and please give me your opinion...'cuz some folks argue with me (I say they play games with me) that my questions are to picky...(while they admit they haven't used subnetting in the last 20 years....)

Q 1:You ordered a public available IPv4 subnet. The provider assigned you the subnet 111.111.222.0/30 .How many hosts can you use in this subnet ? What is the ID and what is the BC address ?Please write down the mask in a non CIDR way.

​

Q2:

You configure a bare metal server with an IPv4 address...however, the cli complains about a bad mask error. The mask of /27 is correct ...what is the problem here and how can you solve it ?

Server-1(config-if)# ip address 209.165.200.224 255.255.255.224

Bad mask /27 for address 209.165.200.224

Does anyone else hate building packages from source?

I swear every time someone mentions linux they say something about how you "get to" build packages from source and how it's somehow superior to downloading pre-built binaries. Usually I try to install packages from package managers, a non-insignificant amount of the time the things I want to install are 6+ months out of date. I would love to build everything from source, but EVERY time I have ever built a package from source it invariably involves manually managing a bunch of minor versions of dependencies that conflict with other installed packages, not to mention a whole slew of non-denoscriptive error messages every time the build fails. I think the MINIMUM time it has ever taken me to build something from source has involved 30+ minutes of troubleshooting. But maybe if I'm really lucky, the package will have a barely-used IRC channel where I can ask a question and after waiting two days the only response will be from someone calling me an idiot for asking.

Am I alone here? Am I doing something wrong? Does building from source always have to be a such a tedious process?

vizex/vizexdf - a terminal tool to visually display disk usage and directory information (Python)

I just added a new feature to my terminal program vizex. It graphically displays disk usage and now displays directory data in the terminal by calling vizexdf and allows you to sort data, show hidden files, create an alias of your current call, and output data as CSV or JSON file.

​

Check it out, and please report if you encounter any bugs. Any feedback and contribution are appreciated!
