Great morning already at Umbraco in the city Manchester, with a great space and great talks and plenty of new faces. Hello MCR! 👋

Noooooooo..... what clown designed this?!

The new Meetup.com has a "paper" texture background.. I "designed" websites like this in the 90s!
Very sorry for the visually impaired people but I'm adding some screenshots with the extremely clownish new look of the […]

The ONE thing I was really missing after the switch from chrome-based browsers was proper PWA support. Firefox has just brought this feature back and it's absolutely great. I love being able to pretend Gmail is a windows app, but with all the benefits of my […]

Last week @lotte and I talked to our colleague Kenn (or as Lotte dubbed him: Mr. Search 🕵️).
We did a good deep dive into the new Umbraco.Cms.Search package that the CMS team has just released. Talking about easier faceting, the many extension points in this […]

Hot on the heels of the Umbraco 16.2 RC release, @lotte and I did a DevRel Deep Dive with special guests @iOvergaard
We had a look at a great new feature: UFM Javascript (like) expressions. This powerful syntax can greatly enhance what's displayed in your […]

Me and @lotte are still working on making the experience of open sourcing an Umbraco Cloud site great.

In this DevRel Deep Dive, we work with community contributions (woohoo @Jmayn, @mattbrailsford and @rockerby!) and we get a tip from the Cloud team to reduce […]

At the airport I see someone pour water into a device unknown to me. My bullshit alarm is going off, but what is it?

I'd never be able to ask a search engine what it is (this introvert ✋ is certainly not going to ask the person what that is 😅).
Describing it […]

I was today years old when I learned in Google Sheets that I don't have to manually change the X-axis and Series every month to maintain my "only show the last 12 months" chart. 🤦

So after a slight (31 day 😂) outage, my blog is back!

⚡ A power outage at home, managed to completely kill the Raspberry Pi it was running on.

I had a new Pi the next day, but I wanted to up my game...
So I had to learn how to run Umbraco sites on Docker. My […]

Oh my, I just discovered #homeassistant has an API. 🙌
I already have Cloudflare tunnels installed to give my HA a public URL, combined with this, I can do very interesting things, like remote switching based on.. well whatever I want. Publish a node in […]

My question from 16 years and 3 months ago has been closed because it's too opinionated 😂 Cassini died like.. a decade ago? 😅
Screenshot of an email saying that my question "What are the (dis)advantages of using Cassini instead of IIS?" is "opinion-based. It is closed and not accepting answers."

I am looking for OLD Umbraco versions, screenshots, videos, anything you have laying around. Mostly interested in v2, 3 and flavors of v4.

Anyone still running a v2 website?! 🙈

#umbraco
Screenhot of the old umbraco.org website. This features a screenshot of the Umbraco 2.0 backoffice. On the page is a few blog posts with the following text: Download 02.17.05 - New release.... The file for download had two bugs which caused problems to creating documents with the correct name in the tree and problems with inserting macros into the editor. The download section has been updated so these errors doesn't occur. So if you've downloaded today before 12.15 please download again! 02.16.05 - Say no more - it's here.... 02.14.05 - Hold your breath; umbraco 2.0 shipping the 16th All that's left is installer and the test website that will ship with the standard umbraco release!

Do you use any APIs from your Umbraco sites?

So delighted by the work of my colleagues on Umbraco Authorized Services. https://marketplace.umbraco.com/package/umbraco.authorizedservices

I had to replace a GitHub integration yesterday and to my horror had to […]

Hey all, did you know that HQ's very own @emaburst and @lotte are speaking at this year's .NET Conf? Well now you do!
