Personally, I’ve been using and administrating Linux systems for almost two decades now, and my own knowledge of the things on that list is either very limited or not existing. Sure, I know about pipes and signals, but even with basic things like permissions there are some tricky questions that I’m not sure I can get right on the first go.
Some of the topics mentioned are simple and straight-forward and will only need a few minutes or a couple of hours to get up to speed with. Others – are huge areas which might take years, if not decades (like networking, for example).
PHP 7.0.0 has been released for a year now. I wasn’t in a rush to migrate to it, but with all the cool features and performance optimization, it’s definitely something I wanted to look into rather sooner than later.
It turns out that I’ve done my first PHP 7 migration a week ago, when I upgraded my laptop to Fedora 25. Yup, that’s right. It’s a bit embarrassing, but I have been developing on PHP 7 for a week without even noticing it.
$ php --version

I think that was due to a few things:
It’s been quite a busy week, so my attention was all over the place.
PHP 7 backward compatibility is pretty awesome. There are only a few things that need fixing in the older code bases, but if you haven’t been living under a rock for the last few years, you probably have nothing to change or worry about.
Most of the code I’m working on runs through TravisCI builds, which are executed on both PHP 5.6 and PHP 7. Since we had this for a while now, most, if not all, of our code is PHP 7 compatible.
The absolute lack of any issues for the last week, related to this upgrade, is encouraging. Now I will probably try to upgrade our servers sooner than later.
With that, I’ll go back to the wonderful and exciting world of PHP, leaving you to decide whether I’m very serious or very sarcastic…
This is basically a much simplified setup of a few of their services, such as Amazon EC2, Amazon EIP, Amazon AIM, Amazon EBS, Amazon Route 53, and a few others. For those, who don’t want to figure out all the intricacies of the infrastructure setup, just pick a VPC, click a few buttons and be ready to go, whether you want a plain operating system, or an application (like WordPress) already installed.
It’s an interesting move into the lower level web and VPS hosting. I don’t think all the hosting companies will survive this, but for those that will do, the changes are coming, I think.
5 Whys is an iterative interrogative technique used to explore the cause-and-effect relationships underlying a particular problem. The primary goal of the technique is to determine the root cause of a defect or problem by repeating the question “Why?” Each answer forms the basis of the next question. The “5” in the name derives from an anecdotal observation on the number of iterations needed to resolve the problem.
What do I think of immediately? Louis CK bit on parenting and kids’ ability to ask an infinite number of “Why?” questions:
Well, I guess, kids, much like me until today, don’t know that you only need 5. Or 6.
Moving large amounts of on-premises data to the cloud as part of a migration effort is still more challenging than it should be! Even with high-end connections, moving petabytes or exabytes of film vaults, financial records, satellite imagery, or scientific data across the Internet can take years or decades. On the business side, adding new networking or better connectivity to data centers that are scheduled to be decommissioned after a migration is expensive and hard to justify.
In order to meet the needs of these customers, we are launching Snowmobile today. This secure data truck stores up to 100 PB of data and can help you to move exabytes to AWS in a matter of weeks (you can get more than one if necessary). Designed to meet the needs of our customers in the financial services, media & entertainment, scientific, and other industries, Snowmobile attaches to your network and appears as a local, NFS-mounted volume. You can use your existing backup and archiving tools to fill it up with data destined for Amazon Simple Storage Service (S3) or Amazon Glacier.
I know, I know, it looks like a regular truck with a shipping container on it. But I’m pretty sure it’s VERY different from the inside. With all that storage, networking, power, and cooling needed, it would be awesome to take a pick into this thing.
