Node v6.9.0 (LTS)

This is a security release. All Node.js users should consult the security release summary at https://nodejs.org/en/blog/vulnerability/october-2016-security-releases/ for details on patched vulnerabilities.
v6.9.0 marks the transition of Node.js v6 into Long Term Support (LTS) with the codename “Boron”. The v6 release line now moves in to “Active LTS” and will remain so until April 2018. After that time it will move in to “Maintenance” until end of life in April 2019.
Some highlights for users migrating from Node.js v4 LTS “Argon” to Node.js v6 LTS “Boron”:
The Buffer() constructor has been deprecated in the documentation in favour of the new Buffer.from(), Buffer.alloc() and Buffer.allocUnsafe() for security and safety. See the Buffer documentation for full details. As a documentation-only deprecation there will be no warnings printed to standard error, this is the first phase in a long deprecation cycle.
Support has been dropped for Windows Vista and earlier and macOS 10.7 and earlier.
Many warning messages and

Amazon Aurora Update – Call Lambda Functions From Stored Procedures; Load Data From S3

Many AWS services work just fine by themselves, but even better together! This important aspect of our model allows you to select a single service, learn about it, get some experience with it, and then extend your span to other related services over time. On the other hand, opportunities to make the services work together are ever-present, and we have a number of them on our customer-driven roadmap.
Today I would like to tell you about two new features for Amazon Aurora, our MySQL-compatible relational database:
Lambda Function Invocation – The stored procedures that you create within your Amazon Aurora databases can now invoke AWS Lambda functions.
Load Data From S3 – You can now import data stored in an Amazon Simple Storage Service (S3) bucket into a table in an Amazon Aurora database.
Because both of these features involve Amazon Aurora and another AWS service, you must grant Amazon

Upcoming changes/fixes to HTTP/2 support in the next Apache httpd release

So, Apache 2.4.24 is about to get tagged and tested Real Soon Now and I managed to
find some time to work on proxy setups and mod_h2. Which was needed badly. The result –
so far – is the shiny v1.7.5
which you can drop into an Apache 2.4.23.

If you still run the plain vanilla mod_h2 that comes with Apache 2.4.23, you
will get several benefits from upgrading (be it from here or via the next Apache release). I
describe those in more detail below:

Timeouts

Connection timeouts are only active while doing IO. When the backend is happily chewing on a request,
mod_http2 will wait very patiently for it to produce something. Only when request processing reads or
writes and is blocked will the timeout happen. This also means that ProxyTimeout is treated
separately from Timeout, as it should

NoSQL Data Modeling Techniques

NoSQL databases are often compared by various non-functional criteria, such as scalability, performance, and consistency. This aspect of NoSQL is well-studied both in practice and theory because specific non-functional properties are often the main justification for NoSQL usage and fundamental results on distributed systems like the CAP theorem apply well to NoSQL systems.  At the same time, NoSQL data modeling is not so well studied and lacks the systematic theory found in relational databases. In this article I provide a short comparison of NoSQL system families from the data modeling point of view and digest several common modeling techniques.
I would like to thank Daniel Kirkdorffer who reviewed the article and cleaned up the grammar.
To  explore data modeling techniques, we have to start with a more or less systematic view of NoSQL data models that preferably reveals trends and interconnections. The following figure depicts imaginary “evolution” of the major NoSQL system families, namely, Key-Value stores, BigTable-style

A Linked Data Overview for Web API Developers

For a while now, I’ve held the belief that the biggest reason people get the whole “REST” thing wrong is because they are looking at Roy Fielding’s doctoral dissertation – the paper that coins the term “REST” – as a prescription for how to design APIs.
There are 2 things wrong here that I think explain the current state of the API world when it comes to REST. First, is the idea that the terms and descriptions in the paper can be exclusively applied to the server. Reading Fielding’s dissertation (and if you read it, I would encourage you to read the entire paper, not just chapter 5), it’s pretty clear that he wasn’t looking at the world so narrowly, but rather was describing the entire system – the interactions between all of the components in a network-oriented architecture. Of possible greater importance, though, was that Fielding wasn’t trying to create

How breakpoints are set

I am fascinated by the debuggers. I love them so much that I wrote a small and very basic debugger as one of my projects recently. In this post I am going to write down what I’ve learned about how can a debugger set a breakpoint.. This post can be divided into these following sections.What’s a breakpoint?What’s a debugger?What does the debugger need to do to set a breakpoint?How can the debugger make the debuggee process halt?
What’s a breakpoint?
A breakpoint makes your program stop whenever a certain point in the program is reached.
What’s a debugger?
You can consider your debugger to be a program which forks() to create a child process and then calls execl() to load the process we want to debug. I used execl() in my code, but any of the system calls from the exec family of functions can be used.
The debugger processAnd here’s the run_child() function which

Doudou Linux – For children from 2 to 12 years old

“DoudouLinux reveals to children the creative, educative, cultural and fun potential that is lying dormant inside every computer.”

DoudouLinux is specially designed for children to make computer use as easy and pleasant as possible for them (and for their parents too! [1]), while taking care of children self-fulfillment. DoudouLinux provides tens of applications that suit children from 2 to 12 years old and gives them an environment as easy to use as a gaming console. Kids can learn, discover and have fun without Dad and Mum always watching!

But DoudouLinux also makes it easy for Dad and Mum. Available as an autorun CDROM, DoudouLinux does not need installing. It does not touch the data in the computer it runs on, nor the system installed on the computer. Shipped with built-in content filtering, it prevents children from accidentally visiting unsavory web sites [2]. It also preserves user privacy on the Internet, removes ads
