How to Install Adobe Acrobat Reader on Ubuntu 18.04 Bionic Beaver Linux - LinuxConfig.org
The objective is to install Adobe Acrobat Reader on Ubuntu 18.04 Bionic Beaver Linux.

Please note that Adobe no longer supports Acrobat Reader for Linux. The latest native Linux version is 9.5.5 dated from 26/04/2013. From this reason you should refrain using/installing Adobe Acrobat Reader if possible to avoid potential vulnerabilities and hacker exploits.

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.

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:

[SOLVED] disable AAAA response for a given domain - General - Pi-hole Userspace
Q: Is it possible to configure Pi-hole to return only A and not AAAA for a given domain?
The use case is pretty simple - IPv6 is provided via tunnel (HE broker) and accessing local (== in-country) resources via IPv6 is not desirable.
(me: returning '[::]' for every host in a domain does avoid a client attempting to contact a host outside of the local network, but the DNS server (dnsmasq) still produces a valid AAAA record/response, therefore some clients might attempt to still contact a host, and they'll be reaching a local(/ly forwarded?) server)

How to fix the Docker and UFW security flaw - TechRepublic
It has been discovered the Docker doesn't always honor UFW rules. Jack Wallen demonstrates and shows how to configure Docker so that it will.

If you use Docker on Linux, chances are your system firewall might be relegated to Uncomplicated Firewall (UFW). If that's the case, you may not know this, but the combination of Docker and UFW poses a bit of a security issue. Why? Because Docker actually bypasses UFW and directly alters iptables, such that a container can bind to a port. This means all those UFW rules you have set won't apply to Docker containers.

Let me demonstrate this.

I'm going to set up UFW (running on Ubuntu Server 16.04), so that the only thing it will allow through is SSH traffic. To do this, I open a terminal and issue the following commands: [...]

Create a Linux Swap File | Linuxize
Swap is a space on a disk that is used when the amount of physical RAM memory is full. When a Linux system runs out of RAM, inactive pages are moved from the RAM to the swap space.

Swap space can take the form of either a dedicated swap partition or a swap file. In most cases when running Linux on a virtual machine a swap partition is not present so our only option is to create a swap file.

This tutorial was tested on Linux systems with Ubuntu 18.04 and CentOS 7 but it should work with any other Linux distribution.

How to Start Docker Containers Automatically - codeburst
When running Docker containers in production ensuring high availability can be challenge. Unlike VMs which run untouched for months or even years, containers are meant to be used for a very short lifespan — typically a few hours or a few days at most. With this constant church, you need a way to ensure that containers that are outdated, vulnerable, or malfunctioning are retired and replaced with new containers. But doing this manually is not scalable, and is prone to human error. The better way is to automate container creation and restarts. There are a few ways you can do this. Before you dive in, take a look at this wiki page with quite a few resources on how to start Docker containers.

Performance: C++ vs Rust - Knoldus Blogs
Rust doesn’t have any special feature which makes it FAST and different from C and/or C++, while it is much safer than C++ because of protection mechanisms it follows which in principle, are also doable in C++, using unique_ptr and shared_ptr and to achieve the same kind of safety that Rust has, we have to do so explicitly and set down standards and force patterns that increase the development effort. With Rust, the major part which makes it safer is that coding mistakes don’t create runtime errors — it creates compilation errors.

Kobo Aura H20 - Screen Issues - RedFlagDeals.com Forums
A: I had that issue with the earlier Aura HD. Same experience with Kobo customer service. So I pried the case open and discovered that its operating system is contained on an internal microSD card that normally sits in a slot held in place by friction only, and it had come loose. I guess I must have dropped it at the wrong angle at some point, and the card just popped out. Initially it was just loose, and gave me erratic freezing for a few days, then it came out completely and everything froze permanently. I pushed it back in place and everything was fine again.
The difficult part is going to be prying open the H2O case so that it doesn't get marked up and lose its waterproofing.

Q: Recently I started to observe this very confusing and annoying, not to say worrying behaviour when having Firefox open and then launching Chromium:

Chromium itself does not show any symptoms. Terminating Chromium again immediately, while Firefox is spinning, does not stop the behaviour any faster. [...]

Calibre plugin on Linux fails to find python.exe · Issue #720 · apprenticeharper/DeDRM_tools
winetricks python26 by defaults installs python.exe to C:\python26\python.exe.

However, DeDRM runs it without path:

DeDRM v6.6.1: Command line: 'WINEPREFIX="/prefix/adobe-digital-editions-2.0"
wine python.exe "/home/user/.config/calibre/plugins/DeDRM/libraryfiles/adobekey.py" "/home/user/.config/calibre/plugins/DeDRM/libraryfiles/winekeysdir"'
wine: cannot find L"C:\\windows\\system32\\python.exe"

This should be easy to to fix, by setting WINEPATH to contain all usual directories where python.exe is installed. For example:

export WINEPATH='C:\python26;C:\windows\system32'
wine python.exe

amazon web services - Is there a way to export an AWS CLI Profile to Environment Variables? - Stack Overflow
Q: When working with certain third-party tools like Terraform, it's not easily possible to specify an AWS CLI profile, and I like working with the environment variables better than the profiles.

Is there a way for me to have the AWS CLI simply export the current profile as AWS_ACCESS_KEY_ID and AWS_SECRET_KEY environment variables to my session?

Mock - Mocking and Testing Library — Mock 1.0.1 documentation [voidspace.org] [archive.org]
mock is a library for testing in Python. It allows you to replace parts of your system under test with mock objects and make assertions about how they have been used.
mock is now part of the Python standard library, available as unittest.mock in Python 3.3 onwards.
mock provides a core Mock class removing the need to create a host of stubs throughout your test suite. After performing an action, you can make assertions about which methods / attributes were used and arguments they were called with. You can also specify return values and set needed attributes in the normal way.

But, unlike those other talks that concerned changes that had already taken place, this talk was about switching open-source graphics projects to using a hosted version of GitLab, which has not yet happened.
