InTheLabWithJayJay.com now with RSS feed

Posted on 2024-06-28 [Friday] by Jay Jay

I added RSS capabilities for InTheLabWithJayJay.com. You can subscribe to the whole thing, or just one channel, or just one show, or just one feature… it was difficulty to create the UI to support that without overcomplicating things. I made the link on the RSS icon support different feed depending on which page you are on.

Refactoring jjlab.net

Posted on 2024-06-27 [Thursday] by Jay Jay

I just spent two whole days refactoring and improving my jjlab.net website.

One thing I had to think very carefully about for my modeling was the class/instance distinction for various things, you can see my notes below.

So channels have shows, and shows have features.

A series has segments, and segments have a video.

A series is an instance of a show, and a segment is an instance of a feature.

Everything is easy when you know how!

Announcing new website for In The Lab With Jay Jay

Posted on 2024-06-16 [Sunday] by Jay Jay

Good news everyone!

The In The Lab With Jay Jay website has been freeloading off jj5.net for a while now, over here: https://www.inthelabwithjayjay.com/in-the-lab/

But I am pleased to announce that it has now been moved into its new and permanent home, over here: InTheLabWithJayJay.com

There is also a short-link domain which will redirect you to the new site which I put into production to keep the links on my business cards short: jjlab.net

Speaking of business cards I had some made to take with me to ElectroneX on Wednesday:

I’m planning to show up in costume and hand out business cards, because I am a *genuine* nerd.

As part of the migration to the new domain I improved the content of the site a bit. There is now an about page with contact info and such and also a support the show page with some ideas about how people can support the show!

Hexing the technical interview meets DALL·E

Posted on 2024-05-26 [Sunday] by Jay Jay

There is a hilarious quote from Aphyr in Hexing the technical interview:

Vidrun, born of the sea-wind through the spruce
Vidrun, green-tinged offshoot of my bough, joy and burden of my life
Vidrun, fierce and clever, may our clan’s wisdom be yours:
Never read Hacker News

I fed it into DALL·E and it gave me this awesomeness:

Forlorn business man
