Qt 5.9 LTS released

I’m happy to let you all know that Qt 5.9.0 has just been released. A lot of work has been put into it, making Qt 5.9 the best Qt version we have developed so far.
With Qt 5.9, we have had a strong focus on performance and stability. We’ve fixed a large number of bugs all across Qt, and we have done a lot of work to improve our continuous integration system. This will make it a lot easier for us to create new releases (both patch level and minor releases) from 5.9 onward.
We’ve also added automated performance regression testing to our testing infrastructure, something that will allow us to continuously monitor our work on improving the performance of Qt. Please have a look at the separate blog post for more details.
The new configuration system used in Qt Lite has received many bug fixes, also here, you can find more detailed information in a

Intel Announces Skylake-X: Bringing 18-Core HCC Silicon to Consumers

There are days in this profession in which I am surprised. The longer I stay in the technology industry, they become further and further apart. There are several reasons to be surprised: someone comes out of the blue with a revolutionary product and the ecosystem/infrastructure to back it up, or a company goes above and beyond a recent mediocre pace to take on the incumbents (with or without significant financial backing). One reason is confusion, as to why such a product would ever be thought of, and another is seeing how one company reacts to another.

We’ve been expecting the next high-end desktop version of Skylake for almost 18 months now, and fully expected it to be an iterative update over Broadwell-E: a couple more cores, a few more dollars, a new socket, and done. Intel has surprised us with at least two of the reasons above: Skylake-X will increase the

MySQL 8.0: Retiring Support for the Query Cache

As Rene wrote on the ProxySQL blog yesterday:
Although MySQL Query Cache was meant to improve performance, it has serious scalability issues and it can easily become a severe bottleneck.
This is indeed something we have observed in the MySQL team for a while. Before we get to the subject of today’s post, let me start with an introduction.
Introduction to Query Cache
The MySQL query cache is a query results cache. It compares incoming queries that start with SEL to a hash table, and if there is a match returns the results from the previous execution of the query. There are some restrictions:
The query must match byte-for-byte (the query cache avoids parsing)
Use of non-deterministic features will result in the query not being cached (including temporary tables, user variables, RAND(), NOW() and UDFs.)
The query cache was designed to not serve stale results.  Any modification to the underlying table(s) results in all cache being invalidated for

Node v8.0.0 Released

The next major release of Node.js brings a range of significant changes and
additions, far too many for us to cover adequately in a blog post such as this.
This article contains a summary of the most significant changes and features.
npm, Inc. recently
announced the release of version
5.0.0 of the npm client and we are happy to include this significant new version
within Node.js 8.0.0.
Node.js 8.0.0 ships with V8 5.8, a significant update to the JavaScript runtime
that includes major improvements in performance and developer facing APIs. Most
significant for Node.js developers is the fact that V8 5.8 is guaranteed to have
forwards ABI compatibility with V8 5.9 and the upcoming V8 6.0, which will help
to ensure stability of the Node.js native addon ecosystem. During Node.js 8’s
lifetime, we plan to move to 5.9 and possibly even 6.0.
The V8 5.8 engine also helps set up a pending transition to the new
TurboFan + Ignition
compiler pipeline, which promises to provide

What Is Hyperledger?

Join over 15, 889 membersAngel investors, Startups & blockchain developers…One of the projects you will inevitably stumble upon when you visit blockchain conferences and follow blockchain news is Hyperledger of the Linux Foundation. But while it is relatively straight forward to understand what cryptocurrencies like Bitcoin and even Ethereum are, it is more difficult to get your head around the Hyperledger initiative. But if you do, you’ll find some exciting projects for non-currency, industrial blockchain applications.What is Hyperledger?Let’s start with what Hyperledger is not: Not a company. Not a cryptocurrency. Not a blockchain. Hyperledger is rather something like a hub for open industrial blockchain development. On its website Hyperledger explains:“Hyperledger is an open source collaborative effort created to advance cross-industry blockchain technologies. It is a global collaboration, hosted by The Linux Foundation, including leaders in finance, banking, Internet of Things, supply chains, manufacturing, and Technology.”Hyperledger does not support Bitcoin or
