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.

Git - Environment Variables
Git always runs inside a bash shell, and uses a number of shell environment variables to determine how it behaves. Occasionally, it comes in handy to know what these are, and how they can be used to make Git behave the way you want it to. This isn’t an exhaustive list of all the environment variables Git pays attention to, but we’ll cover the most useful.

OpenWrt Project: Wi-Fi /etc/config/wireless
The wireless radio UCI configuration is located in /etc/config/wireless.
If the device has ethernet ports, the wireless is turned OFF by default. You can turn it on in /etc/config/wireless by changing option disabled '1' to option disabled '0' (commenting out the line or removing it is sufficient).

Clients in same WLAN can't reach each other - Installing and Using OpenWrt / Network and Wireless Configuration - OpenWrt Forum
Q: Ethernet switch + 2.4G Wifi + 5G Wifi is bridged into one interface and firewall zone (lan).
I updated to LEDE 17.01.0 (stable) and got following problem:
Clients connected to the same Wifi SSID can not communicate with each other (same interface/firewall zone)
PING OPO.lan ( 56(84) bytes of data. From MJ.lan ( icmp_seq=1 Destination Host Unreachable ...
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.

A: The problem usually arises if your home directory is encrypted. The usual solution is to put your keys in a directory other than your home directory, and point your sshd_config file to it.

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.

[SOLVED] Hibernate, 15.10, 16.04, Unity, systemd, tlp, wifi module reload, tuxonice
I thought I should share this in case anyone else has the similar problem and wants to know how to solve it. With the new systemd configuration, the Unity menu's "hibernate" option does not call on pm-hibernate. It instead uses the hibernate and sleep service of logind / systemd. I'm using a tuxonice kernel, and the tlp power management setup on a thinkpad w520, running Ubuntu 16.04 (devel). I think this article is still relevant even if you don't have tlp or tuxonice, since it's systemd that changes how suspend and hibernate work.

When this laptop suspends or hibernates, sometimes the wifi stops working when it wakes back up. The solution is to unload the wifi device driver module prior to sleep, and then reload it upon resume, the way the "hibernate" script does, and "pm-hibernate" also did.

How To Get A Global Menu In Xubuntu 16.04 Or Lubuntu 16.04 (Using TopMenu) ~ Web Upd8: Ubuntu / Linux blog
TopMenu (a global menu for MATE, Xfce and LXDE panels) is available in the official Ubuntu 16.04 repositories and it works great in Ubuntu MATE 16.04, but it doesn't work in Xubuntu 16.04 and Lubuntu 16.04 by simply installing the panel applet package.

Here's how to get TopMenu to work in Xubuntu 16.04 and Lubuntu 16.04, using the official packages, with a minor tweak.

topmenu-gtk.git - A Gtk+ module and Mate/Xfce panel applets for a global menubar.
Requirements and compatibility:

Currently, TopMenu ships as a panel applet for either Mate 1.8, Xfce >= 4.8 (Gtk+2 versions only), or LXPanel. The Mate applet would be relatively easy to port to Gnome 2.

Gtk+2 is the preferred toolkit, albeit Gtk+3 is partially supported. Plugins are shipped for Qt 4 and some Mozilla apps (Firefox, Thunderbird and Zotero). Note that, except in the Gtk+ 3 case, menu bars will always be rendered using the Gtk+ 2 theme.

FS#1960 : hostapd/netifd: multicast_to_unicast/hairpin not set for dynamic vlan, ap not in isolate mode
I noticed that multicast_to_unicast and hairpin_mode are not set on the dynamically created wlan interfaces, and the wireless ap is not running in isolate mode. This is because these interfaces are created by hostapd, unlike other wlan interfaces which are created from netifd/system-linux.

The attached patch fixes this:
- it sets ap_isolate for the hostapd interface, if the interface is using dynamic vlan
- it sets multicast_to_unicast and hairpin_mode after the dynamic interface is created

I haven’t handled the case where the isolate option is not set for the wifi interface, or where multicast_to_unicast is not set on the bridge, since this requires passing additional information to hostapd, and I wasn’t sure what the preferred way to do this would be. I’d probably overload the ap_isolate option to have value 2 mean that multicast_to_unicast and hairpin_mode should be set.

FS#714 : ARP/Broadcast does not reach other clients in the same WLAN
I have the default bridge with ethernet and WLAN in it. When i try to send data from a client to another, both connected to the same WLAN SSID, it doesn’t work (Destination unreachable).
Wireshark shows that it sends endless ARP requests to Broadcast, but the other clients in that WLAN never get it (and therefore can’t answer). The broadcast gets still delivery to every client connected through Ethernet. If i create a second WLAN SSID (even on the same adapter) and and add it to the bridge, it gets also all broadcast packets from the other WLAN...
So if i put the 2 clients in different WLAN SSIDs or ethernet they get the broadcast from each other, but not when both are connected to the same.

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.

RPI falls back to 1280x720 from x1024. - Raspberry Pi Forums
Q: I have an HDMI->VGA converter module connected to my 'pi, as I have a bunch of TFT VGA monitors lying around, but no HDMI ones.

When I boot the 'pi with the cable attached, it comes up nicely in 1280x1024 as I told it to:


(hdmi_mode=35 is 1280x1024@60Hz in group 2)
However, somehow, the mode drops to a 60Hz 1280x720 mode when the monitor is not connected during boot. I was hoping to prevent these problems by specifying hdmi_force_hotplug=1, and directly specifying a mode that I want.
Why does it drop to a lower resolution if the monitor is not connected?
Just to be sure: the /proc/cmdline file shows "fbheight=720", so it is not my VGA converter that isn't booted correctly and somehow converting the 1280x1024 mode into 1280x720 (as if such a cheap piece of electronics would be capable of such a feat).

Conditional filters in config.txt - Raspberry Pi Documentation
When a single SD card (or card image) is being used with one Pi and one monitor, it is easy to set config.txt as required for that specific combination and keep it that way, amending it only when something changes.

However, if one Pi is swapped between different monitors, or if the SD card (or card image) is being swapped between multiple Pis, a single set of settings may no longer be sufficient. Conditional filters allow you to define certain sections of the config file to be used only in specific cases, allowing a single config.txt to create different configurations when read by different hardware.

Subpixel layout - Lagom LCD test
Each pixel on an LCD screen consists of three subpixels: red, green, and blue (RGB), that are sitting next to each other. Most operating systems since about 2003 can improve the quality of on-screen text by using these subpixels. However, this only works if the operating system knows how the subpixels are arranged. For the majority of the monitors, the arrangement is RGB (red on the left, green in the middle, and blue on the right). However, on an occasional monitor, it is the other way around (BGR). And if you orient your monitor in portrait mode, the subpixel layout can be V-RGB (vertical RGB) or V-BGR.

Q: If possible, I'd like to set aside 1024Mb of the 4Gb memory available for GPU memory use.

I've tried adding the 'gpu_mem_1024' command in config.txt which then sees me with 64Mb on reboot.
I've tried setting the maximum setting in Raspberry Pi Configuration for GPU memory, which is "896"
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. [...]

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.

Build your own Command Line with ANSI escape codes
Everyone is used to programs printing out output in a terminal that scrolls as new text appears, but that's not all your can do: your program can color your text, move the cursor up, down, left or right, or clear portions of the screen if you are going to re-print them later. This is what lets programs like Git implement its dynamic progress indicators, and Vim or Bash implement their editors that let you modify already-displayed text without scrolling the terminal.

How to do local port forwarding with iptables - Stack Overflow
Q: I have an application (server) listening on port 8080. I want to be able to forward port 80 to it, such that hitting http://localhost resolves my application (on localhost:8080).

This should be generalized for any port mapping (e.g. 80:8080 => P_src:P_target), and use best practices for modern *nix machines (e.g. Ubuntu).

N.B. This is all done locally, so there is no need to accept connections from anyone but localhost.

(Solved) Flaky wifi with WRT1900ACS v2 and Android phones - Installing and Using OpenWrt - OpenWrt Forum
Q: I have a wrt1900acs v2 running the latest wifi drivers packaged by @eduperez and it is giving me nothing but problems.

Specifically my Android phones simply refuse to stay connected. Recently it's gotten to the point where it hardly will even connect at all and I've turned it off so that my older tp-link devices are the only APs. We've had hot weather, and I wonder if that's relevant because it was never this bad before.

Rebooting the WRT device seems to fix the problem for a few hours. [...]

BusyBox - The Swiss Army Knife of Embedded Linux
BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides minimalist replacements for most of the utilities you usually find in GNU coreutils, util-linux, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts.

Setting up wireless roaming using 802.11r fast transition on OpenWRT · morph027
Ages ago, i was setting up 802.11r the complicated way using all the r0kh and r1kh lists across all access points, which worked well but was a little pita to setup.

After creating a little helper, i just discovered that recent OpenWRT builds can cope with the option ft_psk_generate_local to dynamically create the RADIUS keys and stuff. Even with Luci support, just enable 802.11r Fast Transition and Generate PMK locally, set a Mobility Domain (same across all AP’s per SSID) and a NAS ID (unique, i’d still prefer the BSSID w/o the colons) and it works out of the box.
