Maya is a hypotetical cupcake shop owner. Like many small business owners, she is trying her best to make it all work for her and her employees. Knowing that she needed a presence in the Apple App Store, but unable to afford a custom design from a development company, Maya hired a small shop specialized in providing business like her with a good enough app to enable her to connect with her customers with a price that she could afford. She was happy, so were her clients, but now Apple changed her policies for the App Store and her app is in danger of being removed for not being original enough.
These type of little ISV building apps for small business owners with prices much more reasonable than those practices by bespoke solution developers have their days numbered. Apparently Apple does not consider them a valid citizen of the App Store developer community. With the recent changes in their policies, Apple has the right to ban apps that appear to have been created by a template/generational app.
In this sense a programmer is a miniscientist. Scientists create approximate models for some idealized version of the world to make predictions about it. As long as the model’s predictions come true, everything is fine; when the predicted events differ from the actual ones, scientists revise their models to reduce the discrepancy. In a similar vein, when programmers are given a task, they create a first design, turn it into code, evaluate it with actual users, and iteratively refine the design until the program’s behavior closely matches the desired product.
Fantastic quote from how to design programs, one of the best books about programming ever released.
Creating NodeJS modules with Rust - sample webapp session from Amora Labs on Vimeo.
In this article I’ll show you how to build Rust-based NodeJS modules by exploring how to improve a naive webapp bottleneck. I thought this was a better example than the standard hello world we tend to see in these type of article, still, there are many ways to solve the problem presented here and before complaining to me that the one true solution to this problem lies elsewhere, one should remember that this is a demo crafted to show the reader about NodeJS modules. What is presented here is not a real product. So without further ado, lets first check what is that we are building here.
“A social network is disempowering because you put a lot of energy into it, all your personal data out there, and tell it who your friends are. You can only use that information inside the silo of that particular social network.”
What was the event all about
Brazilian development communities are very organized with constant meetups and chatty online groups focused on specifics points of interest, regions or technologies. Most of these online groups are based on Telegram instant messaging app and basically, people talk all day long. It was in one of such small talk conversations that one group member mentioned an Add-on he created, some other members expressed interest in knowing more about Add-ons because they wanted to port some web development focused WebExtensions from Chrome to Firefox. Thats how we decided to run a hack day event focused on porting Add-ons, it all begun with a single instant message.
Message launching the idea of an Add-on event
As the idea matured, we learned that Firefox is yet to add the WebExtensions DevTools API, so our Add-on porting day would pivot into an Add-on creation day.

Então, você está organizando meetups, oficinas ou ensinando a Web, e está se perguntando qual a melhor forma de treinar seus facilitadores? Bom, eu não vou afirmar que eu sei qual a melhor forma de realizar esses treinamentos mas nesse pequeno artigo eu vou mostrar uma forma que funciona muito bem para mim, eu chamo de treinamento em ondas.
DB Lib is a minimalistic database library for LiveCode that works on Desktop and Mobile and allows you to build database-savvy apps without writing SQL directly. This post is to introduce a great new feature called Remote DB Lib. As you may know from posts on the How To Use LiveCode mailing list and forums, many developers would like to use DB Lib in their apps over the internet. Like all other database libraries that work on top of RevDB, DB Lib (until today) needed to connect directly to the database server to work and this is not a good solution for apps that work over the internet since exposing MySQL to the internet at large is a huge security risk.
Today I am releasing the first version of a drop-in replacement library called Remote DB Lib. This new library has the same API as the current DB Lib but instead of working on top of RevDB, it works alongside a matching PHP file on your server, it is this PHP file that actually talks to the database server. The Remote DB Lib picks all your DB Lib calls and packs it on an encrypted message that is sent to the PHP file where it is decrypted and executed. This library is using state of the art AES 256 encryption (you can also add a free SSL certificate from Let’s Encrypt to add even more security) to protect your data.
