Gave Gemini's note taker a spin for a sync with my colleague. The next steps summarisation is hilariously accurate. 😂

Credit where due. 😝

Scale problems hit differently in the #Kubernetes community. 😅
Screenshot of a message in the #kuberentes-users Slack channel of the Kubernetes community that says: "@channel If this notification is the first time you have looked at kubernetes-users in the last 6 months, could you leave the channel? We are hitting a per-channel limit on the number of users, and new users want to join. Thanks!" A lot of people have reacted to the message with varying emojis and the message has 12 replies (not captured in the screenshot).

Saw the Sonnet 3.7 announcement in the email ~20 mins after it reached my inbox. Went to the gptel issue with half a mind to request supporting a new model and with half a mind that it would already be there. And I was right. What's best is that they also added a small snippet that works already! ❤️
GitHub issue titled Claude 3.7 Sonnet Support #662 on the github repo https://github.com/karthink/gptel/. Issue descritpion contains a elisp snippet to use Sonnet 3.7 with gptel in Emacs. Full link to the issue: https://github.com/karthink/gptel/issues/662

In some cultures the number 13 is considered unlucky, while in others its considered lucky.

The number of additions / deletions in my last pull request at work reflects this well. 😂
Picture contains +13 (in green), -13 (green) showing the number of additions and deletions respectively in a GitHub Pull Request. Also shows 2 green boxes and 2 red boxes for a visual indicator of the size of lines added and lines removed, in this case being exactly the same.

Nice try Google.
A screenshot of a search on the Apple App Store. The search bar has the keyword “perplexity ai”. Top result is Google Gemini with a label to indicate that it is an Ad. The second result (not an ad) is for the Perplexity app itself.

Am I doing code review right? 😁
A change suggestion on a GitHub PR. Content contains a highlighted tab in a file with spaces. The change suggestion suggest to replace the tab with spaces and the accompanying comment reads: A clever tab sneaked its way into space territory. Let's send it to another dimension!

I haven’t seen this shortcut until today.
Maybe this is a new feature they just added? Even the CSS is broken for the menu, but I don’t care. It works and it’s a huge relief that this exists! Along with some other nifty ones!

My blueskyroast is ready. Wasn’t anticipating being bucketed as a memelord. 😂

Probably not an exact science but this is funny nonetheless.

And “is here to delete your negative vibes” is exactly what I’m here for so maybe this is an exact science after all. 😄

Is there a strong correlation to the spike in the usage of “schadenfreude” around 1989 with the fall of the Berlin Wall also in the same year?

Or perhaps a causation in one way or another with Germany being the world’s center of attention?

Any historians / linguists here who know more?

I had a good weekend. Practiced tabla. Played drums. Hung out with a couple of RecurseCenter alums. And then hosted some friends for dinner tonight.

No wonder I didn’t realise the weekend breezing away.

My favourite coffee cup broke today. 😭
A metallic blue colored ceramic coffee cup with a broken handle lying next to it. The cup has an image of a gravel beach with pine trees and a wooden walkway etched on it. Text on the coffee cup says: Sand Harbor Lake Tahoe Nevada State Park

Always a great feeling when I can put in some #ASCIIArt into my docs.

Testing for time ranges always confuses me up. So I made (no LLMs!) this number timeline to describe the time ranges that I'm testing for and I feel really proud of the how this looks.

Is it as readable to new eyes as I think?
The image contains an ASCII art to depict a number line from -12 to 3 with varying ranges marked up by dots and arrows in text. Some of the ranges for example are: -12 to -10, -9 to 0, -11 to 3.

8. Getting those bad rolls out early.

Did you know that #Python will pre-allocate commonly used integers, strings as a performance optimization? For example, ints in the range of -5 to 256.

This is true even if you arrive at the same number indirectly in this range indirectly. Eg in screenshot.

What's your favourite Python trivia?
Example of how Python reuses the same pre-allocated object for small integers between -5 to 256 as a performance optimization.

I got a little mixed up when I was following the arrows to the bit vector. And then caught myself saying that’s not right and traced back again.

Highlighted in the image where the mix up happened for me.

Maybe different arrow lines (dots, dashes) could help? (Color is probably not an option?)

Yep. Also small correction: The limit is 72 chars and not 56. I did a quick test in Python to verify this.
