How AWS came to be

There are lots of stories about the formation of AWS, but this much we know: 10 years ago, Amazon Web Services, the cloud Infrastructure as a Service arm of Amazon.com, was launched with little fanfare as a side business for Amazon.com. Today, it’s a highly successful company in its own right, riding a remarkable $10 billion run rate.
In fact, according to data from Synergy Research, in the decade since its launch, AWS has grown into the most successful cloud infrastructure company on the planet, garnering more than 30 percent of the market. That’s more than its three closest rivals — Microsoft, IBM and Google — combined (and by a fair margin).

What you may not know is that the roots for the idea of AWS go back to the 2000 timeframe when Amazon was a far different company than it is today — simply an e-commerce company struggling with scale problems. Those issues

Aaron Swartz Ebook’s DRM Has Been Cracked

Slashdot reader jenningsthecat writes: From Hackaday comes news that the collected writings of Aaron Swartz, released as a watermarked eBook by publishing company Verso Books, has had its watermarking scheme cracked by The Institute for Biblio-Immunology, who also published a guide for removing the BooXtream watermarks.

The writings of Aaron Swartz, with DRM applied? Oh, the irony. Still, at least the DRM employed doesn’t restrict a user from reading the book on any and all capable devices, so it’s not a very intrusive form of DRM. But I somehow doubt that Mr. Swartz would take any comfort from that…

The React Fact That Will Change Your Mindset

THE FACT: ReactDOM.render is not destructive
If you repeatedly call ReactDOM.render on a component, passing in different props each time, then React doesn’t tear down that component and start from scratch. React updates the component’s props while maintaining its internal state. Before showing how this fact will change your mindset, let’s demonstrate its veracity with the aid of an example.
The example shows a Timer component that increments every second. The colour of the number displayed alternates between red and blue every other second. The Timer stores the seconds count in state and the display colour in props. To toggle the colour, we run a setTimeout every two seconds that calls ReactDOM.render passing the new colour prop to the Timer. You can see that ReactDOM.render is not destructive because the count, held in state, doesn’t reset when we change the colour:

You Don’t Need the React Router
Let’s modify the Timer example so that,

Oracle May Have Stopped Funding and Developing Java EE

While anticipating new features in Java 9, developers also have other concerns, according to an anonymous Slashdot reader:
ArsTechnica is reporting that Oracle has quietly pulled funding and development efforts away from Java EE, the server-side Java technology that is part of hundreds of thousands of Internet and business applications. Java EE even plays an integral role for many apps that aren’t otherwise based on Java, and customers and partners have invested time and code. It wouldn’t be the first time this has happened, but the implications are huge for Java as a platform.

“It’s a dangerous game they’re playing…” says one member of the Java Community Process Executive Committee. “It’s amazing — there’s a company here that’s making us miss Sun.” Oracle’s former Java evangelist even left the company in March and became a spokesman for the “Java EE Guardians,” who have now created an online petition asking Oracle to

Running I3 Window Manager on Ubuntu for Windows

That might be the longest title for a blog post ever, but it’s kind of hard to describe what’s going on here if you’re not familiar with the latest updates from Microsoft land. Here’s a quick refresher:

This spring Microsoft announced Bash on Ubuntu on Windows, also known as the Windows Subsystem for Linux. Read the post, the FAQ, etc in that link. I’ll summarize: Microsoft wants to make Windows the best place for ALL developers to work. A lofty and ambitious goal, to say the least. Their crazy idea – translate Linux system calls into NT Kernel calls using a small shim layer.

This is not a virtual machine. The system calls are translated by the shim layer (WSL) and run directly on the NT Kernel.

This is kind of a Big Deal. If it works, it has the potential to win back many developers who abandoned the Windows platform years ago

Bidding war with Salesforce drove up Microsoft’s LinkedIn bill

A bidding war with Salesforce.com forced Microsoft to pay nearly $6bn extra to seal its planned takeover of LinkedIn last month, according to new details released on Friday.The contest eventually led Salesforce to offer $500m more than Microsoft, at least on paper, though its cash-and-stock offer was heavily dependent on its own share price, in contrast to the all-cash bid from the software company.A month-long back-and-forth between the two rivals pushed the value of the all-cash deal to $26bn, making it the third-largest acquisition in the tech industry.Details of the frenzied bidding were revealed in a regulatory filing that LinkedIn made with the Securities and Exchange Commission ahead of a shareholder vote to approve the deal.The high price that Microsoft ended up paying could now lead to deeper cost-cutting at LinkedIn after the deal is completed. Microsoft chief executive Satya Nadella warned Jeff Weiner, his counterpart at LinkedIn, during the
