Opera today launched version 50 of its desktop browser. Sadly, this release doesn’t come with a cake to celebrate this milestone (not even a tiny cupcake), but the newest release does include a new feature that makes sure that nobody can mine crytocurrencies in your browser.
In Opera, this new cryptojacking feature is automatically enabled when you turn on the browser’s ad blocking tool.

For years, TrueCrypt was the encryption tool of choice for Linux users. It worked well, and it did everything you could ever want. Then one day, the project was discontinued. Ever since then, Linux users have been scrambling to find an encryption tool that works as well.
For most, the best tool to use is VeraCrypt. The main reason that VeraCrypt stands out from the rest of the new encryption tools is that it is a “fork” from the old TrueCrypt code. This means if you’ve used TrueCrypt for years but want something that is actively maintained, you can install VeraCrypt on Linux and everything will continue to work.

Wait, Linux needs antivirus and anti-malware solutions? I thought it was immune to such things. Perhaps a bit of clarification is necessary here. First and foremost, no operating system is 100 percent immune to attack. Whether a machine is online or offline, it can fall victim to malicious code.
Although Linux is less prone to such attacks than, say, Windows, there is no absolute when it comes to security. I have witnessed, first hand, Linux servers hit by rootkits that were so nasty, the only solution was to reinstall and hope the data backup was current. I’ve been a victim of a (very brief) hacker getting onto my desktop, because I accidentally left desktop sharing running (that was certainly an eye opener). The lesson? Even Linux can be vulnerable.

The VPN (Virtual Private Network) server provides the network technology that will allow us to extend the reach capabilities of our local network over the Internet, a great example of this would be the possibility for two branches to communicate using the internet as the sole means.

Chances are, you’re looking to squeeze out as much performance from your Linux servers and desktops as possible. This is especially so with regards to networking. With Linux, there are so many tweaks you can undertake to optimize a machine, it’s mind blowing.
One such tweak that can significantly decrease your DNS lookups is by adding dnsmasq into the mix.
Dnsmasq is a lightweight DHCP and DNS caching nameserver. Unlike BIND, dnsmasq is incredibly simple to get up and running. The benefits of adding this will be quite obvious (like your DNS queries getting dramatically faster).
