[$] Improving communities through documentation

Zur Kategorie wechselnLinux Tipps vom | Quelle: lwn.net Direktlink direkt öffnen

Documentation, said Riona MacNamara at the beginning of her Open Source Summit Japan 2019 talk, is the superpower that we can use to energize users and developers; it is an important part of the creation of a vibrant and inclusive community. While there are a number of roadblocks that can impede participation in a development community, many of those can be addressed with better documentation. The talk was a call for all projects to think about what they are trying to accomplish and to ensure that their documentation is helping to get there.

Match lines with GNU sed with a pattern that contains white spaces

Zur Kategorie wechselnLinux Tipps vom | Quelle: reddit.com Direktlink direkt öffnen

Hi, i'm not aure whether this is the right sub for my question. Sorry if not. Anyway here is my problem:

I can't find a way how to match a line with a pattern containing white spaces with gnu sed. I want to uncomment the matching lines.

Here is a sample of my file :

anon-access = read

auth-access = write

Expected result :

anon-access = read auth-access = write

I'm trying something like this :

sed -i '/#.* auth-access = write /s/#//'

Also tried this:

$ STRING="auth-access = write" $ sed -i '/#.* $STRING /s/#//'

Any help would be appreciated!

React Native on Linux

Zur Kategorie wechselnLinux Tipps vom | Quelle: reddit.com Direktlink direkt öffnen

Hey guys, I have a question.

I've been using Hackintosh for the past few months, and it's actually quite good but I want to make the switch to Linux.

I already tried Arch and am on Ubuntu right now. I love how good it is in combination with i3. The problem is I tend to build React-Native apps for clients quite often. I have an old Macbook Pro that is relatively bad with builds. I tried building android apps on 16.04 Ubuntu but it's giving me tons of errors.

My question is:

Is anyone using any Linux distro to develop React Native apps? And is it any viable if so?

I really, really want to make the switch to Linux and this is the only drawback so far.

Thanks in advance.

Cross platform repo management

Zur Kategorie wechselnLinux Tipps vom | Quelle: reddit.com Direktlink direkt öffnen

Good day Linux people!

Sorry if this has been asked or does not belong here. I am just trying to get a feel for the current options. I work for a large company that has a large but shrinking list of supported distributions. In the end we will be a primarily RHEL/Ubuntu shop. One requirement from on high is a supported repo management solution. Ideally a single source that can support both rpm and deb based packages, but otherwise, if not plausible, what might be the best solution otherwise. We currently use Red Hat Satellite for RHEL and a local Aptly repo for Ubuntu.

I greatly appreciate the collective input from this sub and anyone who may of gone down this road once before. Thank you again everyone!

PGP Packet Library

Zur Kategorie wechselnLinux Tipps vom | Quelle: reddit.com Direktlink direkt öffnen

Hi everyone,

We (https://summitto.com) open-sourced a C++17 based PGP packet library. Using the library, you can create packets, encode and decode packet data and create a PGP key from e.g. a raw elliptic curve point. We've seen quite a lot of bad publicity for PGP lately, but we hope this helps those who are still using it. Lo and behold:

Where does one start learning Linux

Zur Kategorie wechselnLinux Tipps vom | Quelle: reddit.com Direktlink direkt öffnen

Hi all,

I’m one of those guys that gets scared when he sees Linux being used on servers at work. I need to change this.

I have used Linux on my Pi and followed instructions to get me where I needed to be, but I want to spend the next 6-12 months learning it properly.

I have access to Udemy and wondered if there are any good courses I can buy there or somewhere else to follow and get me over this scary edge?

What did you do?

I’m a Windows guy and a certified network engineer so this would be great to add.

Thanks

Cook: security things in Linux v5.2

Zur Kategorie wechselnLinux Tipps vom | Quelle: lwn.net Direktlink direkt öffnen

Over on his blog, Kees Cook runs through the security changes that came in Linux 5.2. "While the SLUB and SLAB allocator freelists have been randomized for a while now, the overarching page allocator itself wasn’t. This meant that anything doing allocation outside of the kmem_cache/kmalloc() would have deterministic placement in memory. This is bad both for security and for some cache management cases. Dan Williams implemented this randomization under CONFIG_SHUFFLE_PAGE_ALLOCATOR now, which provides additional uncertainty to memory layouts, though at a rather low granularity of 4MB (see SHUFFLE_ORDER). Also note that this feature needs to be enabled at boot time with page_alloc.shuffle=1 unless you have direct-mapped memory-side-cache (you can check the state at /sys/module/page_alloc/parameters/shuffle)."

Usually, these changes are made within Microsoft Windows, as the Logitech corporation has little to no Linux support, and hasn’t announced any plans to support the platform in the future. As a result, Linux fans with a […]

PSA: If you have linux on a different disk and want to install windows on another, unplug your linux disk, or windows will trash your ESP partition

Zur Kategorie wechselnLinux Tipps vom | Quelle: reddit.com Direktlink direkt öffnen

For those interested, I totally forgot about this.

My PC consists of 2 ssd disks and a storage HDD disk.

I have windows installed on one and linux on the other ssd.

I know I can setup a multi boot system using only one ESP pertition, but I wanted independence between one OS and the other.

Before I go further, for those that don't know, the ESP partition is your /boot partition for UEFI setups (I know it's more than that, but I want to keep this simple)

It's pretty straightforward: You mount it, run grub and it will let you boot in UEFI mode - just like you've always done with BIOS.

Microsoft windows creates its own ESP partition unless it does see another ESP partition on any other disk, then, it will procceed to (try to) use that partition as windows ESP partiton in order to boot in UEFI mode. Only it won't use it properly, will trash it, windows will boot in BIOS mode in the end and you won't be able to boot your linux system :) (Thanks microsoft!)

So, in order to keep the harmony, I ended up unplugging the LINUX disk altogether when I had to reinstall windows last week (mobo and cpu upgrade). Forgot about this little fact and had to chroot into my encrypted linux system and recover the esp partition (was quite easy, tho)

I'll leave this here in case anyone runs into the same issue anytime.

:)
