I found this great article of Anton Gostev about Spectre and Meltdown, so I’m reposting it here :

By now, most of you have probably already heard of the biggest disaster in the history of IT – Meltdown and Spectre security vulnerabilities which affect all modern CPUs, from those in desktops and servers, to ones found in smartphones. Unfortunately, there’s much confusion about the level of threat we’re dealing with here, because some of the impacted vendors need reasons to explain the still-missing security patches. But even those who did release a patch, avoid mentioning that it only partially addresses the threat. And, there’s no good explanation of these vulnerabilities on the right level (not for developers), something that just about anyone working in IT could understand to make their own conclusion. So, I decided to give it a shot and deliver just that.

Today I’m glad to publish a guest post about Galera a software that I’ve used in the past to manage a multi-master mysql cluster:

MariaDB Galera Cluster is a multi-master cluster for MariaDB. MariaDB Galera Cluster currently supports only the InnoDB/XtraDB storage engine. It is mostly used for database redundancy as it consists of multiple master servers that are synchronized and connected to each other. In today’s tutorial we are going to learn how to install MariaDB Galera Cluster on a clean Ubuntu 16.04 VPS, on optimized MariaDB hosting.

Today I want to repost a great article first posted on sysadvent blog.

I think it’s a great post that show how to integrate different software to achieve a modern continuos integration.

Docker and the ecosystem around it have done some great things for developers, but from an operational standpoint, it’s mostly just the same old issues with a fresh coat of paint. Real change happens when we change our perspective from Infrastructure (as a Service) to Platform (as a Service), and when the ultimate deployment artifact is a running application instead of a virtual machine.

Even Kubernates still feels a lot like IaaS – just with containers instead of virtual machines. To be fair, there are already some platforms out there that shift the user experience towards the application (Cloud Foundry and Heroku come to mind), but many of them have a large operations burden, or are provided in a SaaS model only.

In the Docker ecosystem we are starting to see more of these types of platforms, the first of which was Dokku which started as a single machine Heroku replacement written in about 100 lines of Bash. Building on top of that work other, richer systems like Deisand Flynn have emerged, as well as custom solutions built in-house, like Yelp’s PaaSta.

Guest post by Emma.

Home automation technology has struggled to gain serious traction because, for all its promised convenience, the current tangle of cords and communication standards still has consumers in knots. New quote-unquote-smart systems have made huge strides recently, but not everyone has chosen invest – yet. Totally “smart” homes still await the mainstream. To unlock this new market, technology companies are looking to a tool we’ve taken to heart already: the smart mobile phone.
