systemd - ArchWiki
systemd is a suite of basic building blocks for a Linux system. It provides a system and service manager that runs as PID 1 and starts the rest of the system. systemd provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. systemd supports SysV and LSB init scripts and works as a replacement for sysvinit. Other parts include a logging daemon, utilities to control basic system configuration like the hostname, date, locale, maintain a list of logged-in users and running containers and virtual machines, system accounts, runtime directories and settings, and daemons to manage simple network configuration, network time synchronization, log forwarding, and name resolution.

I can still reach it from Ethernet or from the other WLAN (5G -> 2.4G and vice versa) but not when both are connected to the same... It works fine if i create 2 different SSIDs on an adapter and put a client in each one.
Multiple clients connected through ethernet can also reach all others.

Solved: Optiplex GX620 memory limitation - Dell Community
The GX620 can support 2 gig modules. With 4 memory slots and a 64 bit CPU and OS it will see 8 Gigs of Ram in bios but you cant use 8. You can only use 3GB or 3.5GB. You CANNOT utilize more memory than 3.5 Gigs even when you install a 64-bit version of your OS This is a GX620 Limitation. Models with Pentium D also support NX and the other requirements for Windows 8.

How to Easily Softmod ANY Fat PS2! | FreeMCBoot & FreeHDBoot Install Tutorial - YouTube
This tutorial has been requested for quite a long time but I waited so long because I was not too keen on the many install methods shown out there. A few recommendations to softmod a PS2 with FreeMCBoot normally include: finding a pre-modded console, using a disc swap trip, using Swap Magic, all of which could be a bit costly or time consuming. With this method all we need is one console and a few tools at our disposal! No swap tricks or discs, no pre-loaded memory card, no reliance on any other system!

This involves installing FreeHDBoot to a hard drive, loading it into the PS2 and using that as our entry point to install FreeMCBoot. That's it! No additional games needed and no need to open up our console!

Power management - ArchWiki
Power management is a feature that turns off the power or switches system's components to a low-power state when inactive.

In Arch Linux, power management consists of two main parts:

* Configuration of the Linux kernel, which interacts with the hardware.
* Kernel parameters
* Kernel modules
* udev rules

* Configuration of userspace tools, which interact with the kernel and react to its events. Many userspace tools also allow to modify kernel configuration in a "user-friendly" way. See #Userspace tools for the options.

NDISwrapper - Wikipedia
NDISwrapper is a free software driver wrapper that enables the use of Windows XP network device drivers (for devices such as PCI cards, USB modems, and routers) on Linux operating systems. NDISwrapper works by implementing the Windows kernel and NDIS APIs and dynamically linking Windows network drivers to this implementation. As a result, it only works on systems based on the instruction set architectures supported by Windows, namely IA-32 and x86-64.

Thinkpad-acpi - ThinkWiki
This is a Linux ACPI driver for the ThinkPad laptops written by Borislav Deianov, and currently maintained by Henrique de Moraes Holschuh and is included with the Linux kernel. It aims to support various features of these laptops which are accessible through the ACPI framework but not otherwise supported by the generic Linux ACPI drivers. As a kernel module, thinkpad-acpi works as a bridge to deliver information about certain hardware events like key presses or control the state of certain hardware features by software.

linux-thinkpad/tp_smapi (Lenovo ThinkPad Laptops kernel module)
ThinkPad laptops include a proprietary interface called SMAPI BIOS (System Management Application Program Interface) which provides some hardware control functionality that is not accessible by other means.

This driver exposes some features of the SMAPI BIOS through a sysfs interface. It is suitable for newer models, on which SMAPI is invoked through IO port writes. Older models use a different SMAPI interface; for those, try the "thinkpad" module from the "tpctl" package.

WARNING: This driver uses undocumented features and direct hardware access. It thus cannot be guaranteed to work, and may cause arbitrary damage (especially on models it wasn't tested on).

mkottman/acpi_call: A linux kernel module that enables calls to ACPI methods through /proc/acpi/call. Now with support for Integer, String and Buffer parameters.
A kernel simple module that enables you to call ACPI methods by writing the method name followed by arguments to /proc/acpi/call.

This module is to be considered a proof-of-concept and has been superseeded by projects like bbswitch. It allows you to tamper with your system and should be used with caution.

hamishcoleman/thinkpad-ec: Infrastructure for examining and patching Thinkpad embedded controller firmware
The main purpose of this software is to patch the EC on xx30 series thinkpads to make the classic 7-row keyboards work. There are also patches included (but disabled by default) to disable the authentic battery validation check.

With the patches included here, you can install the classic keyboard hardware on many xx30 series laptops and make almost every key work properly. The only keys that are not working are Fn+F3 (Battery) and Fn+F12 (Hibernate)

Unfortunately, there are a small number of thinkpads with a model number from the "xx30" series that are using a completely different EC CPU and a different BIOS update strategy. Thus they are not currently able to be patched. This is known to be the case for at least the L430, L530 and E330.

tp-smapi - ThinkWiki
The tp_smapi kernel module exposes some features of the ThinkPad hardware/firmware via a sysfs interface. Currently, the main implemented functionality is control of battery charging and extended battery status. The tp_smapi software package also includes an improved version of the HDAPS driver. The underlying hardware interfaces are SMAPI and direct access to the embedded controller.

This driver uses undocumented features and direct hardware access, so it may work unreliably or even damage your hardware; but so far no such damage has been reported.

If you are installing on a recent Thinkpad that has an Ivy Bridge or newer processor (X230, T430, T530, etc.), tp_smapi will not work. You will be mostly limited to thinkpad-acpi capabilities. You can however set battery charge thresholds with tpacpi-bat.

systemd 183 and newer include a logic to inhibit system shutdowns and sleep states. This is implemented as part of systemd-logind.daemon(8) There are a couple of different use cases for this:

* A CD burning application wants to ensure that the system is not turned off or suspended while the burn process is in progress.
* A package manager wants to ensure that the system is not turned off while a package upgrade is in progress.
* An office suite wants to be notified before system suspend in order to save all data to disk, and delay the suspend logic until all data is written.
* A web browser wants to be notified before system hibernation in order to free its cache to minimize the amount of memory that needs to be virtualized.
* A screen lock tool wants to bring up the screen lock right before suspend, and delay the suspend until that's complete. Applications which want to make use of the inhibition logic shall take an inhibitor lock via the logind D-Bus API.

which doesn't work either. On a couple of occassions I have had the system lock on reboot which required me to take the SD card out and edit config.txt externally. [...]

wiringPi updated to 2.52 for the Raspberry Pi 4B | Wiring Pi
Just a quick post to let you know that you’ll need a new wiringPi for the Raspberry Pi 4B.

To upgrade:

cd /tmp
sudo dpkg -i wiringpi-latest.deb

Check with:

gpio -v

and make sure it’s version 2.52. I’ll push the updated sources shortly.

It will hopefully be part of the official release soon, but for now this will do.

HDMI Configuration - Raspberry Pi Documentation
In the vast majority of cases, simply plugging your HDMI-equipped monitor into the Raspberry Pi using a standard HDMI cable will automatically lead to the Pi using the best resolution the monitor supports. The Raspberry Pi Zero uses a mini HDMI port, so you will need a mini-HDMI-to-full-size-HDMI lead or adapter. On the Raspberry Pi 4 there are two micro HDMI ports, so you will need either one or two micro-HDMI-to-full-size-HDMI leads or adapters, depending on how many displays you wish to attach. You should connect any HDMI leads before turning on the Raspberry Pi.

Preparing Raspberry PI for JTAG Debugging – Sysprogs Tutorials
This tutorial shows how to prepare your Raspberry PI board for debugging with JTAG (we have tested this with Raspberry Pi 1, 2 and 3). Using JTAG will allow debugging the Linux kernel using hardware like Segger J-Link. As Raspberry PI board does not have a connector with a normal JTAG layout, preparing the board for JTAG debugging involves finding the correct pins and wiring them in the correct order. Follow the steps below for a complete walkthrough:

OpenWrt Project: Upgrading OpenWrt firmware via LuCI and CLI
An OpenWrt upgrade will replace the entire current OpenWrt installation with a new version. This includes the Linux kernel, the SquashFS partition and the JFFS2 partition.

The common upgrade paths below will automatically preserve much of the OpenWrt OS configuration by saving and then restoring configuration files in specific common locations (including /etc/config). This will preserve things like OpenWrt network settings, WiFi settings, the device hostname, and so on.
