Lately I was experimenting with GTK and its Ruby bindings and I decided to write a tutorial introducing this functionality. In this post we are going to create a simple ToDo application (something like what we created here with Ruby on Rails) using the gtk3 gem a.k.a. the GTK+ Ruby bindings. Note: The code of the tutorial is available at GitHub . What is GTK+ Quoting the toolkit’s page : GTK+, or the GIMP Toolkit, is a multi-p....

At Localytics, data is central to our mission. One of our core principles is to "lead with data." When I envision that, I often think of an analyst using graphs to make a case for a business decision, or a principal engineer using benchmarks to advocate for a

Originally appeared on Opsgenie Engineering Blog We have been using AWS Lambda for over two years at OpsGenie. Our primary programming language for our Lambda functions is Java. Although Java tends to use more memory compared to other languages such as Node.js and Python, we still allocate more memory than we need for our functions. There are two primary reasons. Sometimes depending on the traffic, there can be unexpected spikes in usage.

I’ve heard the phrase “hungry artist”. It describes people, who’s goal in life is to produce art, but don’t make enough money out of selling their art to sustain comfortable lifestyle. Now, there are a spectrum of reasons why someone would make art. I’d bet most artists, deep down want to be commercially successful. They want their art to be number one on the charts, to be in museum exhibits, and to bring them millions of dollars. They wa....

ok, inspired by a friend, I have decided to make some changes in the way i organise my content on this blog. Separating pure content (in depth article, how-tos, reference post) from the blog in a more casual sense of word. In a follow up to post “We have stopped blogging” – I want to get back to some regular writing. Less formal, more personal, maybe informative maybe not – I don’t know yet, what I know is I want it to be place where I can ..

This may not be my first post of 2018 (or even my second, for that matter), but hey, better late than never. Happy 2018! I’ve said before that I’m not a big fan of New Years’ resolutions. That’s still true. But I am a fan of taking the time to evaluate how my life is going, and course-correcting as necessary. I try to do it every few months, but the start of a year is as good a time as any to take a good hard look in the mirror,..

SoundCloud consists of hundreds of millions of tracks, people, albums, and playlists, and navigating this vast collection of music and personalities poses a large challenge, particularly with so many covers, remixes, and original works all in one place.

I came across a link on Product Hunt to Tailor Brands who do automatic logo creation and branding. It is great to see them still doing well. I used them for my company logo, Sentio Ventures , shortly after they started in 2014!

Sometimes when we are making backups on our files, and specially if you are a Node.js developer, you’ll suffer whilst copying your repositories to another place for making a backup. (Provided you don’t have git for all your repositories) Just do: rsync -av --exclude 'node_modules' source destination And you are set. You could also exclude some other things like adding adding gitignore rules rsync -av --filter=":- .gitignore" source destinat..

Recently, while writing a small Golang program for setting reminders I came across a small confusion that I guess most newcomers to Golang will have - how to organise a package in a way that will enable it to cleanly contain two or more binaries.

You’re an Autolayout Wizard. You know Interface Builder like the back of your hand. Then, one day, you create a simple UIView, add it as a subview with some elegantly crafted constraints, and.. it blows up in your face. What gives? Take a look at this code example that tries to create a UILabel and center it in the view. let centerLabel = UILabel() centerLabel.text = "Perfectly centered!" view.addSubview(centerLabel) NSLayoutConstraint....
