I recently had to upgrade my Linux tiny VM from Ubuntu 23.04 to 24.04.1 LTS. However, as I waited too long, a simple do-release-upgrade no longer worked in January 2025.
An upgrade from 'lunar' to 'noble' is not supported with this tool.
Azure App Service on Linux does not currently support Node 22 LTS. As of January 27th 2025, the latest supported Node.js version on Azure App Service for Linux is Node 20 LTS. The support timeline for Node.js versions on Azure App Service is as follows:
On Ignite Node 22, support was announced for December 2024 but seems to be delayed in rollout. I was unable to find further information though.
App Service is planning to release both Node 22 and Python 3.13 onto App Service for Linux with expected availability in December!

There is no mention of Node 22 LTS support in the current documentation or recent announcements for Azure App Service. It’s worth noting that Azure typically adds support for new Node versions after they are officially released and after completing testing for compatibility with the platform.
In my case Node 22 is now available in Azure Portal.
Node 22 is now available and also present in the documentation; it was added on February 19, 2025.
You might have the problem that when you are opening dev.azure.com you will be redirected to portal.azure.com. Likely you were not looking for portal.azure.com but rather for Azure DevOps. This is how you can find your Azure DevOps organization and gain access back.
DeepSeek’s first generation reasoning models with comparable performance to OpenAI-o1.
In the words of OpenAI.
A new series of AI models designed to spend more time thinking before they respond. As AI becomes more advanced, it will solve increasingly complex and critical problems. It also takes significantly more compute to power these capabilities.

Or as an excerpt from Wikipedia.
It spends time “thinking” before it answers, making it better at complex reasoning tasks, science and programming…

On January 20-24, 2025, we have the World Economic Forum in Switzerland. Last year this caused various DDoS attacks on Swiss websites. If this year we see DDoS activity again is yet unknown. Being only days away from the forum taking place, we might soon see if Switzerland is again in focus of NoName057(16) or other actors.
Ahref has released on their website a tool to have an image processed and returning alt text. Processing images is a good way of utilizing AI in my opinion. The offer is nice as an idea but also convenient as the tokens for image processing are rather expensive. Based on the short texts returned, I imagine they resize the image to smaller before having it processed. Try it out and consider using it for your online posting and have the web more accessible.
A recent study by The Guardian found that AI search engines like ChatGPT Search can be manipulated by hidden information on websites.
Since November 19th, 2024 Azure Functions Flex Consumption is now generally available. I was waiting for this for quite some time but missed the update on the regular Azure updates. Even when filtering, I can’t see an entry on the Azure updates feed, therefore you might have missed this news too, so I’ll share it here as well.
As of January 14, 2025, regional availability is still very limited. For example, it’s not available in Switzerland.
Since the update to macOS Sequoia, you might encounter an error in your browser, specifically in Chrome, when trying to access a resource on your local network, such as a NAS, Plex, or anything else you host yourself.

This is a topic that really threw me for a loop – I have an application which displays a receipt, but it was unable to display it properly. The issue was that my application is running on Domain A (mia.web-performance.ch) and the store that created the receipt is running on Domain B (pia.web-performance.ch). Whenever you clicked the link to view the PDF, you got a blocked page instead.
I spent quite some time searching for answers online, but unfortunately, most of the results I found were unhelpful and didn’t provide any real solutions.
