ATX v3.1 is presented

The first revision of ATX 3 comes with changes to the 12VHPWR connector, where the length of the internal pins of the connector that goes to the PCB has been modified.

Ownership and permissions in files and folders in Linux

In our journey to set up our home server with Debian, we have made a second technical stop to explain what file and folder permissions are in Linux and how they work. This will be necessary to isolate the content that certain services exposed to the Internet will access and write to.

Tour of an Intel factory

In this extensive entry, a tour is made of an Intel integrated circuit encapsulation factory, one of the processes that is causing a bottleneck in certain technologies.

Accessing our server via SSH

Once we have already installed Debian on our machine, the time comes to access it through SSH for the first time. To do this, we will have to find out the IP that has been assigned by the DHCP server, a process that may not be immediate.

Caching in 3D

Intel is going to adopt a 3D stacked cache topology similar to what AMD is now doing with its 3D V-Cache.

Camera at 4.8 million fps

A group of researchers has achieved a camera capable of recording at 4.8 million frames per second using CCD/CMOS sensors, which drastically reduces costs.

RaiserFS begins to disappear

The kernel people have decided to gradually eliminate support for the RaiserFS file system since, today, there are alternatives like BTRFS and ZFS with better functions and better maintenance.

According to Nvidia, native resolution is a thing of the past

Nvidia has said that new scaling technologies, like its DLSS, are here to stay and that native resolutions will not return. The company wants to prioritize efforts to improve its AI over other aspects.

New technique for battery saving

Intel is working on a new technology that improves battery saving that consists of turning off the screen backlight when it is not being looked at.

Configuring the network in Linux

We arrive at the last step in setting up Debian before starting to install and configure services on our home server. Network configuration is fundamental to ensure a static local IP to which we redirect the ports that will listen from the Internet.

The Steam Deck will not update its hardware soon

Valve has said that, although they are already thinking about the Steam Deck 2, the new version will not be ready, at least, until in two years.

Installing Apache in Debian

Finally, the time comes to install services on our home server. We will start with the Apache web server, which will allow us to share HTML web pages with the rest of the world.

Core i7-12700KF

Someone has brought us a Core i7-12700KF. It is an Alder Lake with 8 P cores and 4 E cores that exceeds one million points in exchange for a hefty 125W TDP.
