Your IDE as a presentation tool
I’ve just given my third programming talk where I use only my IDE (integrated development environment) for live coding and no other presentation tool. I noticed the audiences were very pleased with these talks, and I think it’s correlated to using an IDE and not a slides program.

There are days (many days) when you just don’t want to do what you have to do. Anything and everything, no matter how boring it may be, suddenly becomes very interesting and very very important indeed. At first it may be a harmless distraction, like highlighting your notebook.

A reading list for Linux and open source fans
I recently asked our writer community to share with us what they're reading. These folks come from all different walks of life and roles in tech. What they have in common is that they are living and breathing Linux and open source every day.

Drink in this fantastic list. Many of them are free and available to download.

You may see books you've been meaning to get around to, books that are completely new to you, and some that feel like old friends.

We'd love to hear what you think of this list. Share with us in the comments below or on Twitter with #Linuxbooks #opensourcebooks.

What is a blockchain?
Unpacking the complexity of blockchain, term by term.
So, what is a blockchain? It's a complicated question because the inventor of Bitcoin, the pseudonymous Satoshi Nakamoto, didn't use the term in the original Bitcoin paper. For many, “the blockchain” is nothing more than a shorthand for "how Bitcoin works." But more usefully, the blockchain is a distributed ledger, shared by untrusted participants, with strong guarantees about accuracy and consistency. What does that mean? Let's unpack it term by term

Computer Room Temperature Monitoring with a Raspberry Pi
I have long wanted to monitor what my computers and computer room are up to temperature wise. First, in case the air conditioning fails so that I can do something about it and have the facts. Second to understand how hot they get, if they start heating up it can indicate a problem like something covering the air intake and finally learn something about airflow that might mean keeping the computers cooler.

How To Set Up an OpenVPN Server on Ubuntu 16.04
Want to access the Internet safely and securely from your smartphone or laptop when connected to an untrusted network such as the WiFi of a hotel or coffee shop? A Virtual Private Network (VPN) allows you to traverse untrusted networks privately and securely as if you were on a private network. The traffic emerges from the VPN server and continues its journey to the destination.

How To Route Web Traffic Securely Without a VPN Using a SOCKS Tunnel
Sometimes you're on a network that's insecure or has an overly restrictive firewall, and you need to access a website. You want to make sure no one in the middle is watching the traffic.

One solution is a VPN, but many VPNs require special client software on your machine, which you may not have rights to install.

If all you need to secure is your web browsing, there is a simple alternative: a SOCKS 5 proxy tunnel.

A SOCKS proxy is basically an SSH tunnel in which specific applications forward their traffic down the tunnel to the server, and then on the server end, the proxy forwards the traffic out to the general Internet. Unlike a VPN, a SOCKS proxy has to be configured on an app by app basis on the client machine, but can be set up without any specialty client agents.

DNS over HTTPS - Using JSON
Cloudflare offers a DNS over HTTPS resolver at:
https://cloudflare-dns.com/dns-query
Cloudflare’s DNS over HTTPS endpoint also supports JSON format for querying DNS data. For lack of an agreed upon JSON schema for DNS over HTTPS in the IETF, Cloudflare has chosen to follow the same schema as Google’s DNS over HTTPS resolver.

JSON formatted queries are sent using a GET request. When making requests using GET, the DNS query is encoded into the URL. An additional URL parameter of ‘ct’ should indicate the MIME type (application/dns-json).

DNS for Rocket Scientists
This Open Source Guide is about DNS and (mostly) BIND 9.x on Linux (Fedora Core), BSD's (FreeBSD, OpenBSD and NetBSD) and Windows (Windows 7 and 10). It is meant for newbies, Rocket Scientist wannabees and anyone in between.

This Guide was born out of our first attempts a number of years ago at trying to install a much needed DNS service on an early Redhat Linux system. We completed the DNS 'rite of passage' and found it a pretty unedifying and pointless experience.

Promys - Screencasting project
A screencasting system project based on a Pi 3. Nothing very new for such project except that it aims at being very user friendly. Easy setup for users on Windows, Mac and Linux.

User connects to the Promys Device Wifi access point, visits the embedded web page, downloads client application from there and starts it. Almost as easy as ClickShare from BARCO but at a reasonable price (~40€).

It's NOT like a Chromecast device, guests don't have to join hosts wifi network. It's suitable for companies that would like to offer easy screencasting to visitors and employees. It's more similar to Click&Share. I don't see a point using it at home, but, why not?

Database Modelization Anti-Patterns
This example looks a lot like a case of premature optimization, which per Donald Knuth is the root of all evil… in most cases.
The exact quote reads:

Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%.
