git tip: multiple identities

If you are using git version control for personal and work repositories, it is tricky to change your email address (in ~/.gitconfig) to properly use the correct email before committing to a repo (this is what I do, depending on the nature of the repo: personal repo -> personal email, work repo -> work email). … Continue reading git tip: multiple identities

ZeroTurnaround’s Java Tools and Technologies Landscape Report 2016

As of every year, ZeroTurnaround released the yearly report of their survey about Java and Java-related technologies among professional developers. I find this report very interesting, and I usually compare (or discover) existing technology solutions. For example, right now I’m currently thinking about moving to Intellij IDEA. How do you measure up against the report?

OpenVPN with multiple configurations (TCP/UDP) on the same host (with systemd)

As much more people are getting worried about their online privacy (including me), I started to use a server as a VPN termination (with OpenVPN) when I need to access the Internet via non-secure wired or wireless networks (e.g., hotel wireless network, airport Wi-Fi, etc.). Some overzealous network admins, though, try to lock down the … Continue reading OpenVPN with multiple configurations (TCP/UDP) on the same host (with systemd)

PSA: this website now is TLS-enabled

After some thinking, I decided to switch my current domain registrar and hoster: in fact, I stayed for 5 years with Netsons.org for domain registration and hosting. I had a very pleasant experience with them, I will recommend their hosting to everyone (it’s very cheap in the plethora of Italian super-expensive hosters). Since I recently … Continue reading PSA: this website now is TLS-enabled

Spotify puzzles: round two

Some months ago, I began challenging myself with Spotify puzzles: at that time I was dealing with an easy problem; now, the difficulty has increased. The round two consists in the typical “Selection problem“: given an array of values, find the max (or min) k values. I decided to still use Python and to use … Continue reading Spotify puzzles: round two

Packaging software for Debian/Ubuntu: eclipse

Eclipse is my (Java, Python, Ruby, XML, <insert any other text format here) editor of choice, and it has been for many years. One thing that bothers me is that Eclipse package is outdated in Ubuntu: so, instead of using apt, I should resort to download/unpack/copy/create links to install it. These days are finished, though. … Continue reading Packaging software for Debian/Ubuntu: eclipse

After updating to Ubuntu 15.10 a box with an OpenVPN termination I am using to browse when I travel and use insecure networks, my VPN tunnel stops working. I am using, in this particular box, an OpenVPN server that relies on PAM plugin for authentication (and 2-step verification).

Today I had a chance to watch a very talented speaker, Dan Pink, who delivered a mind-blowing presentation about motivation, business and science. This is a presentation from 2009: if … Continue reading Dan Pink: The puzzle of motivation

Getting started with cloud-init and CoreOS

Lately I’ve been experimenting with CoreOS, a Linux distribution that enforces containerization (I made some experiments with Docker and I’d say that this area is fun!). CoreOS layer of containerization was based Docker, but now that they moved to Rocket. Not only Rocket, though: CoreOS brings some curious innovations to lightweight Linux distributions like clusterization … Continue reading Getting started with cloud-init and CoreOS
