Ask HN: Cheap, hackable e-reader?
37 points by 0942v8653 2 hours ago | hide | past | web | 12 comments | favorite I would like to buy a cheap e-reader where I can replace the software with my own (or at least be able to write my own software that I can launch and stay in, with minimal UI chrome around it). Preferably about $50 or under. I would like to have a touch screen or to be able to use most of the buttons.What are some good options for this?

New – Instance Size Flexibility for EC2 Reserved Instances

Reserved Instances allow AWS customers to receive a significant discount on their EC2 usage (up to 75% when compared to On-Demand pricing), along with capacity reservation when the RIs are purchased for use in a specific Availability Zone (AZ).
Late last year we made Reserved Instances more flexible with the launch of Regional RIs that apply the discount to any AZ in the Region, along with Convertible RIs that allow you to change the instance family and other parameters associated with a Reserved Instance. Both types of RIs reduce your management overhead and provide you with additional options. When you use Regional RIs you can launch an instance without having to worry about launching in the AZ that is eligible for the RI discount. When you use Convertible RIs you can ensure that your RIs remain well-fitted to your usage, even as your choice of instance types and sizes varies

Linux 4.11 rc2

Linus Torvalds: As usual, the week after rc1 tends to be fairly quiet when people are still looking for bugs and taking a breather after the merge window.

Why Is Gopher Still Relevant?

Most people who “get” Gopher are already using it and instinctively
understand why Gopher is still useful and handy. On the other hand,
people who inhabit the Web generation after
Gopher’s decline only see Gopherspace
as a prototype Web or a historical curiosity, not a world in its own
right — and more to the point, being only such a “prototype,” there is the
wide belief that Gopher plays no relevant role in today’s Internet and is
therefore
unnecessary. This has led to many regrettable consequences, such as the
neglect of servers and clients, or even active removal of support.

However, there is much to be gained from a heterogeneous network environment
where there are multiple methods of information access, and while the Web will
confidently remain the primary means of Internet information dissemination,
there continues to be a role for Gopher-based resources even in this modern
age. Gopher and the Web can, and should, continue to coexist.

The misconception that the modern renaissance of
Gopherspace

Simple example of machine learning in TensorFlow

README.md

This is a bare bottom example of TensorFlow, a machine learning package published by Google. You will not find a simpler introduction to it.

In each example, a straight line is fit to some data. Values for the slope and y-intercept of the line that best fit the data are determined using gradient descent. If you do not know about gradient descent, check out the Wikipedia page (link).

After creating the required variables, the error between the data and the line is defined. The definition of the error is plugged into the optimizer. TensorFlow is then started and the optimizer is repeatedly called. This iteratively fits the line to the data by minimizing the error.

Read the scripts in this order:

serial.py
tensor.py
bigdata.py
Serial.py

The purpose of this script is to illustrate the nuts and bolts of a TensorFlow model. The script makes it easy to understand how the model is put together.

Introducing Create React Native App

Today we’re announcing Create React Native App: a new tool that makes it significantly easier to get started with a React Native project! It’s heavily inspired by the design of Create React App and is the product of a collaboration between Facebook and Expo (formerly Exponent).Many developers struggle with installing and configuring React Native’s current native build dependencies, especially for Android. With Create React Native App, there’s no need to use Xcode or Android Studio, and you can develop for your iOS device using Linux or Windows. This is accomplished using the Expo app, which loads and runs CRNA projects written in pure JavaScript without compiling any native code.Try creating a new project (replace with suitable yarn commands if you have it installed):$ npm i -g create-react-native-app
$ create-react-native-app my-project
$ cd my-project
$ npm startThis will start the React Native packager and print a QR code. Open it in the Expo app
