Changing language of your all slides in presentation – spellchecker in PowerPoint

I wonder how often you are struggling with a small issue that is very irritating and there is a low chance of solving it or at least you do not see any potential for addressing it. For me, such a thing was PowerPoint spellchecker. Right now, I would say that most of your presentation should be done in English and this is a natural choice for me. And there is a small issue related to PowerPoint. Microsoft application is not perfect and it has small issues with languages: Read more

FluentValidation.Validators.UnitTestExtension version 1.4

I just managed to publish a new version of package FluentValidation.Validators.UnitTestExtension. This package allows you to write unit tests for Fluent Validators in a more effective way.

With version 1.4 following changes have been introduced:

  • new verifiers that check the configuration of EnumValidator, MaxLengthValidator, MinLenghtValidator, ExactLengthValidator, ExclusiveBetweenValidator and InclusiveBetweenValidator
  • support for .NETStandard 1.6 and .NETStandard 2.0

More information about the project is available on GitHub.

How to enable/disable Azure Function programmatically

Today I would like to write about something different. I am curious… Have you ever thought about enabling/disabling Azure Function by code? In such scenario, we would be able to decide about the state of the function directly from our application. I believe that you can find a lot of useful scenarios for such behaviour. I will provide two of them.

The first one. We have some resource that is not so fast and we would like to reduce the frequency of using it during the day. In such scenario, we can use Azure Storage Queue as a buffer for actions to compute. And turn on Azure Function only for a night and then in the morning turn it off again.

Another one is strictly connected with a question that I hear quite often during meetups or hackathons. Are we able to turn off function when we use all free capacity that is provided by Azure? People that are offering some small solution for public access would like to avoid the situation when they will need to pay for it. Read more

How you can improve code quality in your project?

Last Saturday during my lecture about code quality I was a bit shocked how many people didn’t know the most accessible tools that can improve code quality. You should remember that cost of quality improvements will be low only when we will think about those issues from the early beginning of the project. Every additional day when we are not monitoring and improving quality will increase the cost of potential quality issues fixes in future.

Of course, I would assume that each time we are trying to deliver good quality code but we are only humans. So even when we do not have enough budget for refactoring, I would like to advise to start monitoring the quality of code. Then we will be able to check present status of code quality and observe the general trend. It means that we will know where we are in our project. Read more

I would like to invite you to September workshops

We still have few months to September but I would like to invite you to my workshops that will take place in that month.

First of them – CosmosDB – Database for Serverless Era – is part of ProgNET London 2018. I will be conducting 3,5 hours workshop during the second day of the conference (13th September 2018). You will learn how to use CosmosDb in your Serverless solutions. I will start with a short introduction of this service, and will present most essential features of CosmosBD. Then you will be able to learn how you can store and query data with this product. You will then try to build your first Serverless solution that will use CosmosDB as a database. Finally, you will play with query optimisation.

The second one – Serverless in Microsoft Azure – will be conducted in Cracow during conference DevConf 2018. Whole day workshop is planned for the first day of conference – 26th September 2018. During the workshop you will learn how to use Azure Functions, Logic Apps, Flow and Event Grid to build easy scalable and cost-effective back-end for your applications.

And what is the most important with this approach building scalable and secure applications has become easier. You can finally focus on solution creation and express creativity in providing new features.

Still, there is some time to September… I would like to encourage you to buy tickets for conferences right now and save a bit money.
