Tipos de redes WebRTC
Respecto a arquitecturas WebRTC, no hay una bala de plata. Dependendiendo de cual sea el caso de uso, la arquitectura óptima puede variar de un proyecto a otro. Por este motivo, voy a explicar las principales arquitecturas de red que suelen aplicarse en proyectos basados en WebRTC (y principalmente aplicadas al streaming de video), y cuales son los pros y contras de cada uno de ellos.
How to move Javascript functions out of its closure to save memory
Long time ago I talked about a pattern I use (a lot!) abusing the functional methods of Javascript to earn some memory and CPU usage. I promised to create a blog post, and almost 4 months after (too much energy draining work…), here is it.
How to paint over a video with HTML
I recently got to work on a project where I need to capture a camera, sendback some drawed feedback, exchange commands and chat messages (and voice comments), and record everything. I’ve always been interested on using non-mainstream features of the Web Platform, and after taking a look of the current state of the art, I’ve found a way to implement this particular use case using ONLY open and readily available web standards.
Sometimes, when you left out social networks and embrace back the Internet 90’s spirit, you find yourself rediscovering that the Web is still an amazing place :-)
How to simulate Chrome is running in a TTY
I’ve always loved terminals and retro-computing. I find they were a technology that didn’t got fully their full potential due to graphical interfaces (it’s strange I say this since my first computer was a Macintosh LC II at a time where everybody else had at most a PC with Windows 3.11…). That’s the main reason I added support for Unicode BPM plain in Linux kernel for NodeOS, specially to have available the Braille patters used by blessed-contrib to draw graphical diagrams in the terminal. That’s the reason why when I discovered BOOTSTRA.386 project, a Bootstrap theme that mimics a text-mode interface in a website similar to old BBSs (fathers of web forums, and grandfathers of current online walls), I got enthusiastic about the idea of making it compatible with real terminal web browsers like Links, w3m or Lynx.
What's `re-start`?
React Native is a framework derived from React that allow to program mobile native apps using Javascript. It’s only focused on Android and iOS, but its popularity has lead to other implementations of its API for other platforms like Windows, macOS or also web. Thing is, although they share the same APIs and source code is (almost) compatible between them, they are not integrated so it would surface difficulties to add a new platform to an existing code, or forcing to have several different projects that could lead to duplicated efforts or diverge the features of them.
Updates on the freelancer calculator
I’ve been working lately a bit more on the freelancer calculator, and was able to identify and fix some of its errors.
Freelancer calculator
At the same time I work as employee, sometimes I get offers for freelance projects. It’s difficult to find a balanced rate between both schemes, so using Google Spreadsheet I’ve done a calculator to adjust them. The calculator is focused for Spain taxes (one of the reasons texts are in spanish), but should be easy to addapt to other normatives.
OS lifecycle
projectlint is a projects-wide linter and
style checker I’ve been working on during the last weeks. As part of its set of
rules, one of them
ensures that the current version of the operating system where the code is
running is maintained and updated. But, is there a npm package with info about
the operating systems lifecycles? Nope… enter OS lifecycle.
Confirm deletion in RESTful APIs
When designing web services, it’s normal to include an option to delete an user’s account. Since this is an important action (the user and its data will dissapear from the platform), usually this is done by asking him to confirm the operation, with several endpoints one for each operation step. Navigating between different pages is so 2010-style, and there’s no direct mapping at this point between REST APIs and CRUD operations, that I’ve been thinking in a REST compatible alternative: use a token.
redux-offline in Node.js
Experimenting with
redux-offline, I’ve done a
Proof-of-Concept about how to use
redux-offline in a Node.js environment,
like a CLI command. This is useful for example when it’s needed to do an offline
aware application that needs to queue some operations until it’s connected
again.
