Finally updated the #SkybearNET landing page with the Insights feature that's been out for several weeks, and some stylistic changes.

New pricing as well.😉

"Investing in 3x Daily Leveraged Nasdaq 100 ETFs (TQQQ or QQQ3) using QQQ weekly MACD signals" 💸

I have written down the strategy I have been researching and backtesting over the past few months.

I wish history repeats.😅

I finally got some time to implement the "Per Request" insights for #SkybearNET.

You can now drill down at the request level and figure out how your API is behaving, latency timings (DNS, TCP connect, transfer, and total duration), alongside response body sizes and status.

"Logistician - ISTJ" sounded wrong initially, but the more I read about it, the more it fits me. I expected the "Architect - INTJ" type, and in hindsight I can even trace back to the questions that probably tipped me over.

I find this personality test not to be very bullshity.😅

New toy, MSI Summit 13 AI+ Evo. This is a beautiful machine! The build is really good, feels premium, with an amazing keyboard!

Global strongly-consistent Durable Objects.🚀And now the fun part begins. Testing.👌😅

Put them in any region you want. As soon as a quorum replies, the operation is committed.

In the example, a worker in EEUR will get super fast quorums with both DOs in EEUR.

Using @hurldev.bsky.social test scripts running on #SkybearNET has become an indispensable part of my job.
It's SO NICE and easy to do any kind of HTTP testing in a few seconds.

Tens of requests, hundreds of assertions, running every minute, with just a few lines of text. Love it!🚀

Not a bad summary of #SkybearNET by @kagi.com's discuss doc feature.

Been using Kagi since yesterday, and I am quite impressed so far. Zero issues. The assistant works great, and the search results are always good.

Insights overview dashboard live🎉
More to come over the week!😉

#SkybearNET Insights launching this week. Initially, with an overview dashboard across all runs of each script.👌

I will also launch a drill-down dashboard for request level metrics (URLs, status codes, etc) soon after.

Just the tip of the iceberg of what's coming😉
February 2, 2025 at 7:21 PM
All these metrics are now available to be graphed and queried for EACH of request of #SkybearNET😃 Need to decide on which of these should be exposed in the dashboard UI, and how.

I don't want yet to open up a full-blown API until I get some user demand to avoid shoehorning myself early on.

I love it when papers have clear, concrete, and detailed graphs that you can actually understand. Even better when it's from real experiments, and not theoretical.

This whole paper for EPaxos is great!👌

The font is hard to read for me, especially the right side of white text. The heading is fine, but the body is really thin and cramped.

Overall website layout, and interaction, is great. Font choice is the only thing I would personally swap.

If you write technical docs for your projects, personal or at work, learn about the distinction between Tutorials and How-to guides.

We need to write both, but each one has its own distinct goal and approach in order to be valuable and effective.
