Tech Tips

At Black Marble, we have had a long standing Azure DevOps Team Project that we used for end-to-end demos of the principles of DevOps called Living the Dream. This used a legacy codebase, the old Microsoft Fabrikam demo, and showed that can be deployed using modern tools. As I had no similar demo for GitHub Enterprise, I thought it would be interesting to see how the migration process taking my Azure DevOps implementation over to GitHub would go. This is a good learning exercise as it is the type of problem that many of our enterprise clients will need to do if changing DevOps platform. My key aim was to do the minimum to get the CI/CD process moved from Azure Pipelines to GitHub Action ...

Today at Microsoft’s Ignite Conference there have been some very interesting announcements related to Azure DevOps and GitHub. In the recent past, I have seen confusion from our clients as to what is Microsoft’s recommended DevOps solution, given they have both Azure DevOps and GitHub. It is true that Microsoft have said, and continue to say, that GitHub is the ’north star’ the long term destination for all users. However, that does not help clients today. Many of mine ask ‘but I am using Azure DevOps, but all Microsoft seem to talk about is GitHub, is Azure DevOps dead?’. ...

SonarCloud (and it’s on premise equivalent SonarQube) understand the concept of Git branching and PRs (in various platforms, in my case Azure DevOps was the important one). This means you can block the completion of a PR if the new code in the branch/PR does not meet the SonarCloud Quality Gate. A great way to stop the addition of technical debt. However, I recently found a problem when starting to use SonarCloud in an older codebase. You cannot do SonarCloud analysis of a child branch before the main/trunk has been analysed. ...

The OWASP Dependency Checker can be used to check for known vulnerabilities in a variety of eco-systems. This tool produces a HTML based report, but I wanted to expose the issues in SonarCloud. The problem is that SonarCloud does not allow ingestion of OWASP Dependency Checker vulnerabilities out the box. However, there is the option to ingest Generic Issue Data. To make use of this I just needed to change my XML results file to a JSON format ...

In the past I have written most of my Azure DevOps scripts calling the Azure DevOps REST API from PowerShell. This has worked, but did involve a lot of JSON payload handling. A better option these days is to look at the AZ CLI and specifically the azure-devops extension, as this does much of the heavy lifting for you. This does not mean that everything is plain sailing though. Today I hit a problem that took me a while to solve. ...

Today I made the fateful mistake of offering to try to fix a family members home printer. Family IT, and especially printers, the bane of all IT Professionals. The Problem The system in question was a 10 year old setup made up of a Dell Optiplex desktop currently running Windows 10 and an HP M1132 LaserJet multifunction printer. This had all been working until a couple of weeks ago when the PC failed to detect the printer. The printer was uninstalled, assuming that would fix the problem, but the Add Printer tools could not even find the printer. ...

I am currently upgrading a .NET Core 3.1(LTS) MVC website to run on .NET 6, stepping it through intermediate .NET versions to make sure some EF Migrations were done correctly. Everything upgraded without any major issue until the final step to .NET 6. As soon as I did this my MVC pages failed to render, but no error was reported After much fiddling the solution to the problem was pointed out to me by one of my colleagues. The way MVC is shipped with .NET (Core) has changed from being a NuGet package to being part of the framework. This happened a good while ago, but become a blocking issue with .NET Core. ...

We recently hit a problem when we tried to edit a page on anold Umbraco 7 instance. When we tried to edit a page in the Umbraco web UI we got the error ‘failed to retrieve data for content id 1119’ Now this page had been created a long time ago by a user who had since left the company, and this was the root cause. It seems there is an issue with Umbraco and deleted users. To avoid this problem, it is actually recommended you disable old Umbraco user accounts as opposed to deleting them. ...

I posted recently on my experience moving to Hugo from WordPress. One feature lost in the move were the Wordpress plugins used to automatically post to Twitter and LinkedIn when a new blog post was created. I always found this very useful, so looked or a way to replicate this functionality for static pages. The solution I ended up with was Azure Logic Apps. I created a Logic App with a scheduled triggered that checked my blogs’s RSS feed every 30 minutes. If it found the RSS feed had been updated, I then created a bitly link for the new post’s URL, then posts to Email (as a test), Twitter and LinkedIn. ...

Background Over the years, the Black Marble blog server has been hosted on many platforms. It’s previous incarnation was WordPress, running as a network of sites with an aggregated feed. Of late we had found this slow to serve the first page (due to website start-up time) and there was the constant need to keep the instance patched. The time had come for a new solutions, and we picked Hugo Static Pages. ...
