Getting developers is a so huge task, no matter the technology or country/region where you based. We know it.

Today, startups is spending a lot of time and money on looking for the right people to their product development. And is very important to hire more than awesome or skilled developers, They will be part of your initial team, and the product success depends on them.

So, if your startup is backed by some investors, you probably don't want to fall down so quickly.

Facebook will release the next React version: 15.0.0

Image
The next React version will be 15.0.0. Yeah. The versioning scheme has been changed and explained why here.

This change shouldn't materially affect most of you. Moving to major versions simply helps indicate our commitment to stability and gives us the flexibility to add new backwards-compatible features in minor releases. This means we can have fewer major releases and you won't have to wait as long to take advantage of improvements to React. Plus, if you're a component author, this versioning scheme gives you the flexibility to support two major versions of React at the same time so you don't need to leave anyone behind.


The core of the React API has been stable for years. Our business as well as many of yours all depend heavily on the use of React as a core piece of our infrastructure. We're committed to the stability as well as the progress of React going forward.

Then, the results are analyzed to determine whether the change is an improvement worth launching.

This course will cover how to choose and characterize metrics to evaluate your experiments, how to design an experiment with enough statistical power, how to analyze the results and draw valid conclusions, and how to ensure that the the participants of your experiments are adequately protected.

I know a LOT OF services running on Parse. Bad news: Parse will shutdown on 2017 and a lot of startups probably are thinking "what a hell I'm going to do?".

Facebook's Parse had got a huge number of startups, but today they says bye bye. Here the official post.

Migrate to another cloud:  "We’re releasing a database migration tool that lets you migrate data from your Parse app to any MongoDB database. During this migration, the Parse API will continue to operate as usual based on your new database, so this can happen without downtime."

Feel free to put your data on Google Appengine. Here a developer guide by using MongoLab and Google Appengine.
