Nowadays, eating red meat is more and more stigmatized. Not only do the media portray it as unhealthy, but lately even as the biggest factor behind environmental issues. EAT-Lancet paper is just the latest in the series of such alarmist articles. As you can see from the outline, it recommends a diet based on highly processed plant-based foods. No surprise, considering that processed food giants, such as Nestle and Kellogg’s, sponsored it. But fortunately, numerous people have already rebuked the misconceptions, that the paper mentions. Personally, I have liked this Revolution Health Radio interview with Diana Rodgers. You can find it here:
DLNA is a standard for sharing digital media. It is supported by most modern TVs, phones and other devices. So, if you have a Raspberry Pi file server, you can easily use it to stream media. To achieve that, we will install MiniDLNA. This guide assumes you are using Raspbian 9, but the commands should be similar on different flavors of Linux.
You might consider antivirus software unneccessary on a Linux box. But if you are running a public facing server, it might be a good idea to run it regardless. Why is that? Even though malware probably can’t affect your server much, it can still use it to infect users. To prevent that, we will learn how to install and set up automatic ClamAV scans with email notifications. In the examples below, I am using Debian 9, but the commands should be the same for any Linux distribution.
Install and configure ClamAV
You can easily install the antivirus by running the following command:
$ apt install clamav clamscan
ClamAV is pretty well configured out of the box. Usually, I only change the frequency of virus signature database updates. You can do that in /etc/clamav/freshclam.conf by changing the Checks line. Since I run the scan once a day, I lower the frequency of updates to that as well.
This might be the first time you’re hearing about EditorConfig. But don’t worry, I was in the same boat just a couple of months ago. So, what is it? It is a simple file format, that helps keeping coding styles consistent across different editors. And more importantly, across different team members.
How does it work?
EditorConfig consists of two components. Firstly, .editorconfig file, that you put in the root of your project. Secondly, a plugin for the editor of your choice. The .editorconfig file is written in .ini format. You can define things such as number of spaces to indent or whether to use tabs or spaces. Moreover, you can use different settings for different file formats. For complete explanation, head over to the official site. In order to enforce the settings from .editorconfig, you need a plugin for your editor. For the most popular ones, such as Vim, Emacs, Atom, Sublime Text or Brackets, the are plugins readily available. The Jetbrains IDEs even include EditorConfig support in their core.
Red Hook Studios have just released Darkest Dungeon: The Color of Madness. It’s the latest DLC for the critically acclaimed gothic roguelike. In case you haven’t head about it, this RPG is set in Lovecraftian world. So, it is not for the faint of heart. Your heroes will starve, despair, get sick and die. And they will stay dead.
The expansion brings several new features:

I have taken part in the beta testing a I can definitely say you should grab this one. And while you are at it, why don’t you get yourself a copy of Crimson Court as well? If you still need convincing, check the launch trailer:
HTTPS is quickly becoming standard, in no small part thanks to Let’s Encrypt. HTTPS helps keeping ISPs and other third parties from spying on users. But there is one more gaping hole, the DNS protocol. And DNS over TLS aims to plug it.
What is DNS?
“Wait a sec, what’s this DNS stuff?” might be your reaction. DNS, or domain name system, is the Internet’s yellow pages. It translates URLs into IP addresses. So, whenever you type an address into your browser, the computer sends a request to a DNS server. In turn, the DNS server tells it which server to connect to. Most DNS servers use DNSSEC to sign their answers. Thanks to that you be sure the answer you got is not bogus. Unfortunately, the whole communication is in plain text and therefore visible to anyone en route. This is where DNS over TLS comes into picture.
Wordpress is the most popular CMS in the world, powering over 30% of all websites. It owes its popularity to easy of use and a huge number of plugins. The plugins make it possible to turn Wordpress into anything from personal blog a to e-shop. Like others of its kind, Wordpress generates the pages dynamically. In other words, everytime it is accessed, it loads data from database and uses PHP to create a page it serves the visitor. As a result, Wordpress load speed is slower a it requires more resources. That is important point too keep in mind, since over 40% of users leave a page if does not load within 3 seconds.
This is where caching comes into picture. It combines the speed of static sites with the robustness of Wordpress. Instead of generating page on every load, Wordpress saves the resulting page. Other visitors just see this pregenerated static page. This significantly improves Wordpress load speed and saves server resources. And when you post a new article or a comment, the cache is automatically invalidated. So, you don’t have to be afraid, that visitor will see an outdated version.
I have been busy working on a new project for the past several weeks. It has finally reached a state, where I can publicly announce it. So without further ado, welcome Mariner, the command line torrent searcher:
I use torrents for downloading Linux distributions. The reason being, that it is usually faster and easier than digging for the ISOs on the official websites. Still, most torrent trackers are bloated, filled with ads and plagued by popup windows. I could do without those. All this has lead me to write Mariner. As you can see in the animation above, it is a simple command line aplication. It let’s you search for a torrent on multiple trackers at once and find the fastest one. Among other features, it allows you to see the torrent details, download them and directly open them in your torrent application. Moreover, it is asynchronous. That means, it is more responsive than your average web scraper.
If it piqued your interest, you can learn more about Mariner in documentation. Or, you could just check the project page. But if you are looking for a more automatic way to download torrents, check my torrentbox guide.
For the last couple years, mass surveillance has been on the rise. Both governments and private entities alike track our every move online. As a result, our privacy has increasingly eroded. Under such circumstances, it is ever more important to fight for our right for it. But the problem is, that majority of population seems apathetic to this. If you are one of such people, I recommend watching the following TED talk by Glenn Greenwald. It nicely sums up why privacy matters.
