I’m Ferruccio Balestreri I’ve founded and was the CTO at June . Before that I worked at Intercom as an engineer. My hobby is to make small projects every couple of months I make something new to have fun and sharpen my skills.

TL;DR In this article I’ll share my experience building an interactive 3D WebGL-based application for peer-to-peer messaging protocol simulation without writing any single line in JS. You’ll learn how GopherJS and Vecty framework can dramatically lower the complexity of building WebGL-enabled web apps in Go. It’s often said “A picture is worth a thousand words”, but in the era of high-DPI screens and big data, the new idiom is now..

I’ve just released xcat 1.0 and it’s demonstration application after like 5 years of on-off development. Feels good! The genesis of xcat was when my boss, Sid, walked up to me out of the blue and asked if I wanted to go on an all expenses paid trip to Amsterdam. Who the hell wouldn’t say yes to that...

Last week, I gave a presentation at a local LUG (which is a Linux User’s Group, for anyone who hasn’t heard of those before) on the subject of SSH Foo. In UNIX circles, we refer to tricks of the trade as “Kung Fu” or just “Fu” (which sounds rude), so it is spelled “Foo” ;-) In this blog post, I’ll summarize my SSH Foo talk! Be aware that this is not an introduction to SSH, but a more advanced look at some interesting SSH features for t..

Today my Jenkins builds were not working because all of the build slaves were offline. Digging around in the logs showed that the couldn’t connect because of name resolution failures. I use mDNS on my network (the slaves are Mac OS X VMs running on a Mac Mini), and so they were named something like … Continue reading AT&T causes mDNS on Linux To Fail

Do-what-I-mean" (DWIM) functions enable us to introduce new Emacs powers to existing workflows without incurring the typical cost of remembering multiple related functions or introducing yet another key binding. DWIM functions invoke other functions, based on current context. I wanted a small tweak in Ivy's `minibuffer-keyboard-quit' invocation, commonly invoked via C-g key binding: If we have text selected in minibuffer, deselect i....

This sixth monthly edition of “My Robinhood Stock Picks” will probably be the last for a while. With my recent purchase (and financing) of a minivan , as well as the fact I have a more tax-advantaged Individual 401k to put money in that I’ve nowhere near maxes out, I think my money has better use elsewhere.

I spend a fair portion of every day writing programs. As with all professions, using the right tools makes a huge difference in my productivity and general happiness. Having good tools helps me keep my gumption up. One of my favorite books is Zen and the Art of Motorcycle Maintenance . Contrary to what the title suggests, this book is actually not about motorcycles. It’s about a lot of things; one topic is about tools and caring about yo....

Needed to diff two directories, but only interested in file size changes. diff, find, sort, and stat seem to do the job: diff <(find dir1 -type f -exec stat -f '%N %z' '{}' \; | sort) <(find dir2 -type f -exec stat -f '%N %z' '{}' \; | sort) 1,3c1,2 < dir1/one.txt 14 < dir1/subdir/file.txt 5 < dir1/three.txt 7 --- > dir2/one.txt 19 > dir2/two.txt 0 Note: Using diff, find, sort, and stat on macOS. Update 1 I've since learned about mt....

Review of the manga “Opus” by Satoshi Kon. “Opus” is a brilliant postmodernist introspection of the challenges of writing, creativity, and the cliches of pop culture; delivered in a manga format. Author Satoshi Kon worked on this manga between 1995-1996 as it was serialized in “Comic Guy” manga magazine until the magazine closed abruptly in 1996. The final 3 chapters were never finished. Between 1996 and his death in 2010, he sketched o..

The same year I was born, the president of USA, Ronald Reagan, was giving a speech in Germany. I learned about it 31 years later when I saw it on Reddit. As he keeps talking “presidentially,” we can all hear a bang. Unfazed, Reagan comments “Missed me” and tries to continue with the speech. Indeed, it missed him. It wasn’t a gun shot at all, it was a balloon popping. Reagan was shot with a gun six years earlier and still felt the consequenc....

This is a thread for discussing the Ada programming language. There doesn't seem to be many Ada programmers here, but we'll see. The Ada programming language was created for the United States Department of Defense in order to provide a reliable programming language to replace the many hundreds in use there at the time. The specifications of what would be desired in this language went through several transformations, from Strawman to Wo....

Recently I’ve enjoyed reading blog posts by Nikita . You can find the blog here . One blog post I see quoted often is this one (you can read it in 6 languages - that says something). It’s about the disastrous state of current software development. The author brings a lot of good points. The message is that no one puts effort into making software performant. We solve problems by adding complexity, never actually solving the root cause...

It’s been nearly two weeks since I’ve posted anything. In fact, tomorrow marks two weeks since my last post . This is mostly because I’v been under the weather (idiom for being sick for my non-native English readers).

Paul Hudson , over at Hacking with Swift , has written The Complete Guide to Optionals in Swift . One of the many highlights is the nil-coalescing operator . If you're a fan of the C-like syntax in ternary operations , you'd enjoy chaining with Swift's nil-coalescing operator: let players = [ "goose": "run!" ] let move = players["duck1"] ?? players["duck2"] ?? players["duck3"] ?? players["goose"] print("\(String(describing: move))") ..

The straightforward approach was to repeat the encoded sequence over and over until the receiver gets complete data. This simple repetition code was good enough for starter and trivial to implement, but also introduced long delays in case the receiver missed at least on..
