11 min read I get asked a lot which cloud provider I prefer, even by people that know me well, and the answer I give lately really surprises them I think. My answer is: a combination of all of them and colocated environments. I think when it comes to the major players in the cloud world namely GCP, Azure and AWS, most of the offerings are pretty much on-par with each other. The preference people have really comes from the trust in the company’s management of the environment, price, friendliness and familiarity of interface; and clear visibility into what’s going on. Well sure, but that’s only good as long as you’re only using one, but in many enterprises, there are really good reasons to use a combination of cloud providers, combined with on-premise and colocated hardware. Some of these reasons include risk of availability in extreme cases of global outages from a single provider (and there are examples of this in the past,) and others include specific niche offerings that are only offered by one provider and only used by a specific department. Let’s take a look at tools some of the top technology companies use to manage their cloud-hybrid environment.
3 min read We found ourselves with a requirement to download an updated version of a public dataset on a regular basis, so PowerShell + windows scheduler came to mind, since the application runs in a windows environment. But only to find that PowerShell doesn’t make this quite trivial. In PowerShell v5+ we have the Expand-Archive command: Expand-Archive c:\a.zip -DestinationPath c:\a but this doesn’t support gzip or tar gzip is a compression algorithm, and is based on the DEFLATE algorithm, which is a combination of LZ77 and Huffman coding. There’s a…

Scrum team, planning work in 2 week increments, reacting fast to change, following best practices in research, planning, architecture and writing software. The team’s focus is on building great software, so we want them focused on what’s important.
- As a developer, I take on a new feature or bug that’s in the sprint and ready for development, and marks it as development in progress.
- Then I create a new branch off of develop, and do the work.
- Then commit one or more times, and mention #[Work Item Number] in the commit message, along with a description of what changed
- Once I consider the work complete and “tested” locally on my computer, I’ll push the branch, go into TFS and click the shortcut to create a PR
* develop is locked, so all changes have to enter via Pull Requests
- On the next page I’ll make sure everything looks good, by doing one more check of the changes in the code, and click Create
- Done and move on to greater things …
4 min read Whenever I get a new computer, or reinstall Windows and such, I realize and remember that I again have to adjust all the settings to just the way I like them, and usually don’t have time for it. This consists of keyboard shortcuts for the most part on a new setup, but I’m also a big fan of some Resharper features. Resharper can really slow down Visual Studio with defaults, because they enable a lot of features, which although cool and useful, aren’t worth the performance trade-off for me. I…
4 min read Code quality, best practices and standards are often the distinction between projects that are maintainable, secure and scale well, and projects that need to be rewritten every year. We were in the latter category unfortunately for quite a long time, despite everyone preaching best practices and within a group of quite smart individuals. The problem is we all had our own idea of what best practices to apply, what standards to follow and how we defined quality. We had to find a way to track and improve, then we discovered SonarQube.
SonarQube is a static code analysis tool.
It uses language-specific analyzers and rules to scan code for mistakes, some patterns that are known to introduce security vulnerabilities, and code smells [According to Wikipedia and Robert C. Martin “Code smell, also known as bad smell, in computer programming code, refers to any symptom in the source code of a program that possibly indicates a deeper problem.] …
< 1 min read Ideally you already have a snapshot you maintain and have hardened, and just have to clone it when you need new servers deployed. If you have to build a clean image to use for your future VMs:
it’s usually easier to start with an existing VM you’ve configured, because it already has everything you need installed, but it might also have other stuff installed that you don’t necessarily want on every new VM, so here’s a way I quickly set up a new server image:
1. Install a clean version of Windows on a new VM
2. Set up your networking stack, and run Windows Update and install all the updates available…
