Direct IO vs Dax

I understand that both are used to bypass page cache but what are the technical differences between them? And can Dax be used on a regularly formatted ext4 file system?

Infomagic linux developers resource

Hi, I am not crazy tech savvy at all, I am new here to find out what this is. I explore abandoned places as a hobby and I came across an antique store with an unopened box of “infomagic linux developers resource” 6 disc cd sets. I have no idea what these are but I am very curious because I love learning about any and all of my finds. It is the december 1999 version. I will post pictures in an edit when i get the outside wraps wiped and cleaned off.

Hi r/linux,

I recently discovered these devices are planned for a Q3 2019 release, and I was wondering how linux will work on them, since they seem like the first mainstream Arm devices?

nftables wiki down?

I had been trying to set up my nftables firewall on my Debian-based Linux router, but after taking a break from the project it looks like the wiki is down now. Does anyone know if or when it's expected to come back up, or have any recommendations for other resources on configuring nftables?

Venus 0.1.6 - Set wallpapers from Unsplash.com

[Venus on GitHub](https://github.com/AlfredoSequeida/venus) [Venus on PyPI](https://pypi.org/project/venuspy)

Venus is a cross-platform tool I wrote to set random wallpapers from [Unsplash](http://unsplash.com), which started as a Linux project, but since it's written in Python, it didn't take much to add multi-platform support.

As of release 0.1.6 it now also has support to set an interval to change the wallpaper in the config file every X amount of seconds.

To install:

pip3 install venuspy

Feature requests, comments, and insults are welcomed.

ecryptfs-migrate-home is done but the home directory is not really encrypted.

I created a new admin users, logged in as that user and then I ran ecryptfs-migrate-home -u old_user_name

after a while it said it was done and that I should log in as the old_user_name. I did that and everything seems fine.

Then I log out and I log in as the new admin user and go poking in the old_user_name home directory and all the files are readable (after I sudo). It seems like none of the files are actually encrypted.

Then I run ecrypt-migreate-home again and it says the directory is already encrypted but it's clearly not.

This is on mint BTW.

What is going on?

Best DEs for a touchscreen?

So I recently bought a little 2-in-1 (Lenovo Flex with all Intel/Wacom components) that I intend to use as a tablet sometimes and it's gotten me thinking about the state of Linux and touch screen interfaces. I've been distrohopping around a few GNOME distros as its what I'm most familiar with prior to getting a touchscreen. Some little issues I've been having revolve around some interface buttons being small like the noscriptbar buttons or menu buttons. I've remedied a lot with GNOME Tweaks etc and for the most part it's very usable but I'm curious what kind of setups do y'all use for your touchscreen devices?

How do you provide SSH access to developers in your infrastructure

Curious about how do you do it, keeping in mind

\- different teams having access to only those boxes which belong to that team

\- providing ssh access without hand smashing the server.

\- revoking ssh access for someone as and when required.

Would also be interested to know of possible ways to do the above.

Heard the recent AWS announcement for the IAM based ssh access, but would be great to know cloud agnostic ways in which someone solves this problem.

Any way to make xrandr only apply to a certain portion of the screen?

So here's the thing, I dropped my laptop on the bus this morning, now half the screen is dorked. With xrandr, I'm able to make the colors look pretty normal, but then the other half of the screen is completely dorked. Is there any way I can specify a region to operate on with xrandr, or a similar too?
