I've always thought as a layman that the weakest link in all of this is our cosmic distance ladder, seems like the most likely place that errors would stack up and lead us to some wrong conclusions. So may places for things to go wrong, we make a lot of assumptions about type 1a supernovas actually being a constant brightness, dust obscuring our view of them, plus all of the assumptions we've made about even measuring the distance between the ones we've measured. And its not like cosmologists havent acknowledged this, but I think a lot of the hubble tension might be solved once we figure out how to measure these distances more accurately.

The first ever SQL debugger – runs & visualizes your query step-by-step, every clause, condition, expression, incl. GROUP BY, aggregates / windows, DISTINCT (ON), subqueries (even correlated ones!), CTEs, you name it.
You can search for full or partial rows and see the whole query lineage – which intermediate rows from which CTEs/subqueries contributed to the result you're searching for.
Entirely offline & no usage of AI. Free in-browser version (using PGLite WASM), paid desktop version.

this is very cool! Where can I follow you to see updates?
After getting the initial M1 Air, I am still struggling to find a reason to replace it. Still going strong with no hiccups!
agreed, which is awesome, the only thing that worries me is that they will drop support for it earlier than they have to when they want to force people to upgrade eventually. I hope to get 10 years out of my M1

Super cool!
We needed to do something similar one time with 5 large touchscreen tvs that were arranged as a table, where each side needed to be a separate touchscreen application with them all playing a synchronized video in the background but users could interact with things flowing from one end to the other and could send objects from their other apps in any direction to other apps, like users sending things they found to the person on the other side of the table.
We ended up with a trashcan mac pro (thats about all we could find in budget that could drive all the screens at the same time) with apps that were synchronized using redis (I wrote that part). It worked really well, though I didnt get to see the finished product before I left that company. But we always really wanted to have separate computers that were synchronized. We just couldnt get that to be reliable enough - it worked for a while but then various things would throw it out of sync, meaning we would have to restart the applications periodically which wouldnt work.
Something I have always wished we had, since the very early days of PCs was the ability to network devices together in such a way that they could share their resources and collaborate more. Imagine being able to take advantage of all of the computers in an office to do a task like a supercomputer. Of course thats a very hard problem, applications and OSs would need to be designed for it and we would need new algorithms (look how long it took us just to take advantage of multiple processors in the same machine on the same board), but there were some projects out there like seti@home and folding@home that did it somewhat, but I always hoped it would be something that the computers themselves would support.
Don't worry, Windows is still far, far more ubiquitous. The bigger reason people don't play solitaire as much as they used to is that it is no longer the only game installed on their PC.
So many people in the 90s learned solitaire playing it on a work from a lack of other options on their work PC. Now with the so many games on the web and your smartphone, you might not even try it.
People give Microsoft a lot of shit, but including bundled games on what was at the time primarily a business OS was bold, controversial, and brilliant.
ive always seen the reason MS included solitaire and minesweeper was to teach people how to use a mouse and a gui.
I can remember even in the early 2000s when we started installing PCs instead of green screen terminals at different locations having employees play solitaire as a way to get them used to their new computers and learning how to use a mouse.

Would love to get this plugged into intellij/datagrip
This looks really great! How do you make money? Do you charge for deploying these to your platform? I couldnt find anything on pricing
If measurements point to some sort of incongruity, questioning the accuracy of one's ruler is a fools trap. Altering the rulers to remove incongruities results in a spiral of compromises, internal debates that don't result in progress. If one suspects that the rulers are wrong, the answer is to build a better ruler. Not to arbitrarily chop bits off until the difficult observations go away.
I have no doubt that there are great scientist spending their entire careers trying to improve these rulers and measurements, but I also know that there are great scientists spending their entire careers basing everything on the best rulers they have...
