I haven't tried it much but this seems like precisely the problem gitbutler is trying to solve

Presumably there's no way to get someone at Google to query their database and find all the shortened links that go to godbolt.org?

well, I see a flash of a normal page and then it goes to 404

I'm using Chrome, with only uBlock Origin Lite but disabling it ~shows no change~ appears to allow it to work.

Looking at the requests with uBOL disabled, app.68194690.js and 5.5caaec0f.js both returned 404, everything else returned 200/202.

and with uBOL enabled https://plausible.hey.si/js/script.hash.outbound-links.js shows as blocked. maybe that's the issue?

https://www.heymeta.com/sponsor/ returns a 404 currently... is that expected?

seems since it's a float it's only 32-bits, and the representation of both 3.14159274101257324219 and 3.14159265358979323846 is the same in IEEE-754: 0x40490fdb

though I agree that it is odd to see, and not sure I see a reason why they wouldn't use 3.14159265358979323846

makes sense, thanks.

the images on the page are all just base64 encoded right into the html

given that it seems like the entire thing is busted, can anyone explain how the unicorn page is being served?

While it is published on their site, it appears to really just be a summary of the book by Carreyrou? And I have yet to see anyone actually publish any of the dilution ratios and compare that to any existing process, so it seems like an easy-but-easily-incorrect leap to conclude that it is "way more than usual".

Until seeing your comment I had never considered that someone might actually want any of that stuff, so I had never considered selling or otherwise parting with it since it is fun to keep all that stuff around. I'll certainly let you know first if I decide to part with it, though.

One thing that seems to be forgotten or lost in all of these armchair analyses is that while it is true that something like 3mL of blood is collected for a conventional lab test, the machine itself when it runs the test only takes a few microliters (maybe 10s of uL, all of this is depending on the test of course). The rest is frozen for follow-up or repeat testing or used for other tests or just discarded after some time.

EDIT: And my favorite part is the first step the Siemens machines they used for testing is to "dilute" the part of the sample it is going to use (addition of DI water, to get the blood to the desired concentration). That is hard-coded into the protocol, with a specific dilution amount, and it is done for all the official Siemens tests, as well, hah.

As someone who used to work there and has one of those water bottles and likely knows the person selling that one on ebay (based on the username) I find this hilarious...

From my experience buying/getting quotes for Hamilton/Tecan machines, they're more likely in the $150-250k range. At least for the ones much wider and capable than that OpenTrons appears to be.

The interest level in achieving the best result (and the required associated time, patience, planning, skill, and potentially cost) is likely the more limiting factor. I"m saying this as someone that works with vision systems for industrial settings. Often I see garbage images with garbage logic and they complain about garbage output. Then the camera is removed because "it doesn't work".

As someone who works with modern industrial robots, like you'd find in a car factory, the sensors they're using for the arm positioning are unbelievably precise. I can have the robot stopped, with the brakes on, and push on the end of the arm with my fingers and see the joints registering the deviation (and not by 1 or 2 counts, but many more), while I don't perceive any significant movement of the robot.
