Security implications of same shell configuration on both root and user

Hi, i've been setting up my zsh config but i wanted to keep same config for both root and the user, while that is not that hard to do i am wondering how bad is it for security

I understand somebody could add some code and it would execute next time i run a shell as root but how is that different from somebody using sudo in the user zshrc and you dont think much about it and well you could have ran something malicious.. If somebody wants to go even further they could just wait override sudo and get the password, there are other ways that i thought of

(I am sorry if this is confusing, i threw it together in a hurry and my english is kinda rusty)

Dual boot Elementary OS

Iam running a Windows 10 laptop. I tried to install elementary os 5.0 dual boot with Windows. Everything went okey till the installation completed and restart. After restart it shows blank screen after showing elementary os Logo. No updates for hours. Then I boot into Windows and removed Elementary OS. The next time I tried the "TRy Elementary OS' option. But it too doesn't boot up. Some errors are shown after logo like **AMD Vi error: unable to write to iommu perf counter** . I think I done the correct process like GPT selection , tried to make bootable USB with Rufus, Etcher, Live USB Installer. Nothing helped! Any help guys pls?

What happened to my computer ... ?

I had a 11" HP Mini running on a 32bit WIN 7 OS Version. I got tired of it's sluggishness, virus and shrugged it off my hardware with a new fresh install of Linux Mint(LM) 32bit OS version.

Right before I installed LM, I had a problem with disk space which kept prompting me if I try to install new software or download videos or maybe just putting some movies on my HD. It barely allowed my internal 65GB HD to hold even at least 60GB of data.

The magic happened after I installed LM but I don't really know what happened. I could install as much software and as many videos as I could without getting internal disk space errors. My HD can hold as much data as possible. Checked the Disk Usage Analyzer and it looks like it is now operating at 153.1 GB. Up to now I have like more than ten 2 hour long videos on my HD but I haven't really witnessed the sluggishness which was common in WIN 7. I got another 43GB volume or whatever it is which I still don't understand why.

I don't understand how did this happened. I want to understand the internal functioning of my computer but LM left me scratching my head.

Can someone please help?

Are you bored during quarantine? Let's fix some open source project!

Hi,

Recently, because of the quarantine, I had enough free time which I decided to use to find bugs in some more known projects.

So I decided to integrate them with Gitlab CI and provide source code analysis with Sonarcloud, Cppcheck and Coverity Scan.

Some of errors are really hard to fix, but some are really easy like - [https://sonarcloud.io/project/issues?id=qarmin\_bullet3&open=AXErXlMn4lbxEqEHg3Am&resolved=false&rules=cpp%3AS1764&types=BUG](https://sonarcloud.io/project/issues?id=qarmin_bullet3&open=AXErXlMn4lbxEqEHg3Am&resolved=false&rules=cpp%3AS1764&types=BUG)

Most of this projects are created in C/C++ so if you want, you can help and fix some of bugs.

I will try to update and check projects with this utilities once per week.

I'm using Ubuntu(18.04 - 20.04 versions) as base of docker images for Gitlab CI and sometimes it is really hard to get compilation steps for this OS(apt build-dep not always works as expected)

You can find instruction of compilation steps inside "[instrukcja.md](https://instrukcja.md)" and ".gitlab-ci.yml" files in root of projects.

I'm not an expert, so probably a lot of things/integrations could be done a lot of better.

Proxmox VE: restart node due to lock-xxx.conf' - got timeout

From time to time I have to restart the servers due to loss of control.

Configuration:

Supermicro Ultra Server

Intel Xeon Scalable gen2
1Tb RAM
4x4Tb Samsung Data Center SSD


Sometimes I get such messages in the log

Feb 17 02:38:29 kfn1-node4 pvedaemon\[38846\]: can't lock file '/var/lock/qemu-server/lock-141.conf' - got timeout Feb 17 02:38:29 kfn1-node4 pvedaemon\[8817\]: <root@pam> end task UPID:kfn1-node4:000097BE:08EF85DA:5E49EE8B:qmstop:141:root@pam: can't lock file '/var/lock/qemu-server/lock-141.conf' - got timeout

and from this moment on I can't start / stop virtual servers.
Before this problem I always see such messages in the /var/logs/syslog:

Cartesi Scalability on Linux and The CTSI Utility Token

As blockchain projects mature and our understanding of the technology progresses, it becomes ever more clear what challenges impede its mainstream adoption:

* Convenience — developing and using a blockchain application is still an overwhelming task, involving a very difficult learning curve and consequently significantly reducing general interest in the technology;

* Scalability — Blockchains need to perform as well as centralized technology in order to be able to compete with it.
