Twitter Account Suspended
I woke up on June 16th to an email from Twitter stating that they had suspended my Twitter account. It stated that my account had been suspended for violating the Twitter Rules against posting violent threats. I knew I hadn’t personally made those tweets. I immediately thought my account had been compromised even though I… Continue reading Twitter Account Suspended
Figuring out the home network

Connecting to a VPN automatically when not at home
When I’m on my home Wi-Fi, I rarely connect to a VPN. When I’m out, I always make the habit of doing so, except when I forget. I was hoping VPN clients would have a feature to automatically connect based on a list of networks, but after some quick research, I guess not. Maybe I’m… Continue reading Connecting to a VPN automatically when not at home

Running osquery on CoreOS
Most things in CoreOS Container Linux can be run in containers, except when it doesn’t make sense. Here’s how I got osquery up and running. osquery is an operating system instrumentation framework for Windows, OS X (macOS), Linux, and FreeBSD. The tools make low-level operating system analytics and monitoring both performant and intuitive. osquery exposes… Continue reading Running osquery on CoreOS

Update Kubernetes Deployment after pushing image to Docker Hub
I recently moved FilePreviews.io’s workers deployment to Kubernetes in Google Container Engine. After setting the workers up as a Deployment I wondered how this would fit with my current setup for continuous deployment. On a previous setup, I relied on Docker Hub to automatically build, push tagged images, and notify Rancher via a webhook. I… Continue reading Update Kubernetes Deployment after pushing image to Docker Hub

Looking backward and forward
2016 was with no doubt an eventful year for many. On March 12th, I married my high school sweetheart. We’d been together for around 9 years and engaged for like 4 of those. Best day ever. During the last quarter of 2015, we cofounded Alias Payments to build Gasolina Móvil. We became part of Parallel18′s first… Continue reading Looking backward and forward
Upload files to S3 and generate previews using Laravel
I recently put together a PHP client library for FilePreviews and immediately thought about putting together a blog post on how I’d use it. After 6 years, according to this repo, of not writing a single line of PHP, I looked into Laravel since it seems to be the rave these days. Alright, let’s get to… Continue reading Upload files to S3 and generate previews using Laravel
Touch Typing and Programming
Programmers solve problems and most of the time use a keyboard to do so. I firmly believe you need to be able to efficiently express yourself through typing. There’s probably nothing more fundamental in programming than being able to think of something and expressing it in code without losing your train of thought. I say… Continue reading Touch Typing and Programming
Juice Box
A month ago I decided to take another stab at proposing a solution to allow all of us to keep working on great programming workshops. Personally, the biggest headache in each and every one of the workshops that I have organized or participated in is the time and effort it takes to configure and setup… Continue reading Juice Box

Top 20 Hacker and Designer News 2014
Last year around this same date I started The Hacker and Designer News newsletter as a weekly curated recap of the what I thought were the best articles from Hacker News and Designer News on startups, entrepreneurship, hacks, programming, design, etc. I built and open sourced an aggregator to help me collect posts. I later built news.hdn.io using that same… Continue reading Top 20 Hacker and Designer News 2014
File Uploads + CORS + IE
Supporting Internet Explorer is always kind of a drag, but sometimes you just have to. Adding to the mixture file uploads via AJAX and CORS only make it that much more fun. When dealing with AJAX file uploads I always seem to keep going back to jQuery File Upload. Making these file uploads work on… Continue reading File Uploads + CORS + IE
Backup OpenPGP keys on paper
Recently I remember I was keeping a backup of my OpenPGP keys on an external hard drive that any day now could just cease to work. After my first attempts with PGP/GPG where I lost my private keys and could no longer revoke them, I wasn’t planning on loosing another one again. After reading what… Continue reading Backup OpenPGP keys on paper

Getting started with Go
I’ve been using Python for a quite a few years as my main go-to language for building web apps, RESTful API’s, utilities, and much more. It’s the driving power for most of our backends at our startup: Blimp, Blimp Boards, and FilePreviews. I have very few bad things I could argue about Python, but I… Continue reading Getting started with Go

Internet Speed Tests on a Raspberry Pi
A couple of weeks ago soynerdito soynerdito shared a bot he made to tweet internet connection speed results every now and then. I then remembered I had a Raspberry Pi I wasn’t using at all. So I built a small app that runs speed tests every 3 hours. It’s based on speedtest-cli which is a Command line interface for… Continue reading Internet Speed Tests on a Raspberry Pi
The easiest way to add WebSockets to Django
TL;DR – I came up with a very simple solution to handle WebSockets in Django apps. You just install django-websocket-request, run a script and you have WebSockets for your Django app. The cool thing is that this solution makes Django believe its getting a (somewhat) normal HTTP request so you can reuse almost all of you… Continue reading The easiest way to add WebSockets to Django
Auth with JSON Web Tokens
When it comes to implementing authentication on web apps, one solution you’ll definitely hear about first are cookies. Cookie-based authentication uses a server side cookies to authenticate the user on every request. This means that you’ll need to keep a session store, whether it’s on a database or on something like Redis. A solution you’ll… Continue reading Auth with JSON Web Tokens
The Hacker and Designer News Newsletter
After recently building a scraper and web API for The News, I thought it’d be a cool idea to use that data somehow. First thing that came to mind was to build a newsletter. And so The Hacker and Designer News Newsletter was built. Newsletter Every week I’ll send a newsletter with a curated recap… Continue reading The Hacker and Designer News Newsletter
Scraper and Web API for The News
I recently found out about http://thenews.im thanks to @gcollazo. The News is a pretty cool project by ahmetsulek that brings together under one same site LayerVault’s Designer News and Y Combinator’s Hacker News. I decided to take advantage of having all those posts from two different sources together and built a scraper for it with Node.js. Once I had all the posts stored… Continue reading Scraper and Web API for The News

Python shell history
If you’re not a fan of enhanced Python interpreters like IPython or BPython but still do heavy use of it you might have notice how annoying it could get whenever you have to quit it, started again, and remember what was the last things you ran. I do this all the time, usually for… Continue reading Python shell history
Startups of Puerto Rico Platform
Two months ago I opened an issue for CAP-0003 proposing to execute a platform to contain what I’ve been able to identify as useful tools for the Startups of Puerto Rico community.

From Day Job to Entrepreneur: Interview with Giselle Zeno

Since Startup of Puerto Rico and events like Startup After Hours, Founder Institute, Startup Weekend, and others started I’ve slowly but surely seen it… Continue reading From Day Job to Entrepreneur: Interview with Giselle Zeno
Shifting to “new-style” url tag in Django 1.5
Prior to Django 1.3, the syntax for the url tag was {% url project_create %}. Django considered project_create to be a name of a view in your urls.py, not a template variable named project_create. I recently upgraded Blimp from Django 1.4.5 to Django 1.5.1. We have around 200+ template files that were using the old… Continue reading Shifting to “new-style” url tag in Django 1.5
Kippt as an RSS Reader
Last weekend I felt like working on a hack, but what? With the recent news of Google Reader being retired on July 2013 I thought there was something cool to be done with RSS, but what? As I was looking for ideas on my Clips I realized that with Kippt’s latest update, a redesign from ground up and tons of new… Continue reading Kippt as an RSS Reader
