xubuntu - Why does light-locker keep the screen black after unlock? - Ask Ubuntu
Q: A Xubuntu 16.04 fully patched machine with a freshly created user wont let me unlock after using light-locker to lock my screen (regardless if lock was activated manually or via timeout). The screen remains black (but powered) on correct password entry

Killing light-locker from tty1 will reveal the desktop then (and consequently prevents further locking). [...]

A: TL;DR: light-locker keeps the screen black if systemd cannot read /proc

* light-locker depends on dbus providing IPC.
* dbus depends on systemd-logind providing session information.
* systemd-logind depends on /proc providing process information. [...]

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!

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.

Low_On_Memory - Wiki
It's a common dilemma: I just got a brand new Linux machine, loaded it up with lots of expensive RAM, and left it for a day. Now, it's out of memory, or it is swapping! It definitely has enough RAM, so there must be a bug in Linux!I assure you, in almost all cases, your system has plenty of RAM. However, where is all of that RAM going? For what does Linux use all of it? How can I actually tell that I'm out of RAM? Unfortunately, Linux can make these very hard questions to answer. This article will explain in detail many of the ways that Linux uses RAM for things other than user data and how you can tell when your system is _actually_ out of RAM.

The issue could most likely be resolved by clearing everything out and starting it up again but due to #32613 that would result in data loss so I'm avoiding that. Using a different name for the container allows it to be started but this is not ideal.

Using HAProxy with the Proxy Protocol to Better Secure Your Database - HAProxy Technologies
The Proxy protocol is a widely used invention of our CTO at HAProxy Technologies, Willy Tarreau, to solve the problem of TCP connection parameters being lost when relaying TCP connections through proxies. Its primary purpose is to chain proxies and reverse-proxies without losing client information, and it’s used and supported by AWS ELB, Apache, NGINX, Varnish, Citrix, and many more (here’s a longer list of Proxy protocol supported technologies).

Bug #1717995 “extra domains not removed from resolv.conf when VP...” : Bugs : systemd package : Ubuntu
I use a VPN (network manager "vpnc" config) to connect to my work network. The gateway is "". When I connect, I get "" added to the "search" line in my /etc/resolv.conf (and /run/resolvconf/interface/systemd-resolved) - which makes perfect sense, the VPN passes this info to me and then I can connect to systems within the work network without having to use a FQDN.

The bug (which is a regression from older versions of Ubuntu) is that when I lose my connection to the VPN (either because I disconnect explicitly, or because the network goes down or I suspend my laptop), the "" domain is not removed from those "search" lines. And for some reason this prevents me from resolving (which prevents me from reconnecting to the VPN). [...]

It is really clean.

Observer Design Pattern | Microsoft Docs
The observer design pattern enables a subscriber to register with and receive notifications from a provider. It is suitable for any scenario that requires push-based notification. The pattern defines a provider (also known as a subject or an observable) and zero, one, or more observers. Observers register with the provider, and whenever a predefined condition, event, or state change occurs, the provider automatically notifies all observers by calling one of their methods. In this method call, the provider can also provide current state information to observers. In the .NET Framework, the observer design pattern is applied by implementing the generic System.IObservable<T> and System.IObserver<T> interfaces. The generic type parameter represents the type that provides notification information.

EDIT: I should have explained this originally, but I used to use YouCompleteMe for this purpose (if I remember correctly it gave me node.js completion) but that's such a huge plugin that comes with much more than I need, and in an effort to slim down my vimrc I'm here asking.

How to securely store API keys - DEV Community 👩‍💻👨‍💻
In the past, I’ve seen many people use git repositories to store sensitive information related to their projects. Lately, I’ve also been seeing some people even announce that they’re storing API keys on their private GitHub repositories. I’m writing this article because I believe that people should understand the risks of storing API keys with your code.

The elusive Palm OS 5.5 Garnet emulator for Windows/Linux
As some of you may undoubtedly know, I'm a bit of a sucker for Palm OS. These past few years, I've been busy collecting ROMs for the Palm OS emulator and simulator, making sure I have all the major Palm OS releases covered. There's really not much of a reason to do this - I have working devices which are a much better option than the emulators/simulators in most cases - other than to have a complete collection I can keep around forever.

Since it’s inception Node.js has depended on the V8 JavaScript engine to provide code execution in the language we all know and love. The V8 JavaScript engine is a JavaScript VM written by Google for the Chrome browser. From the beginning, a primary goal of V8 was to make JavaScript fast, or at least — faster than the competition. For a highly dynamic, loosely typed language this is no easy feat. This piece is about the evolution of V8 and JS engines performance.

Server-side I/O: Node vs. PHP vs. Java vs. Go | Toptal
Understanding the Input/Output (I/O) model of your application can mean the difference between an application that deals with the load it is subjected to, and one that crumples in the face of real-world use cases. Perhaps while your application is small and does not serve high loads, it may matter far less. But as your application’s traffic load increases, working with the wrong I/O model can get you into a world of hurt.
