fidrelity commented on Self-Portrait by Ernst Mach (1886)   publicdomainreview.org/co... · Posted by u/Hooke
libraryofbabel · 5 days ago
The article mentions Mach numbers, but it leaves out what is most interesting about Mach’s place in the history of science, which is as a bridge to Einstein and General Relativity. Essentially Einstein read Mach and took a bunch of mind-bendingly profound but vague philosophical ideas like Mach’s Principle[0] and put together General Relativity out of it. And this self portrait gives that side of Mach too - the philosopher obsessed with phenomenology and how local perception relates to the large scale universe out there.

As a side note, Einstein read Mach but strongly opposed logical positivism[0].

When I read the title the first thing that came to my mind were Magna Tiles. Glad they made it on the list.

It's the only toy in the house that lasted the test of time from she 4-8 (and counting). Also I love tidying up Magna tiles, even that is fun!

My oldest kid got a small sample of Clixco and was surprisingly entertained even with a limited set of possibilities they offered. They're great fidget toys as well.

Nice idea but I think the predictions are way off. I ran a 3:17 in spring and targeting a 3:10 marathon in a couple of weeks.

As unlikely as it sounds Strava predicts 3:13 (think they base it on my last marathon), Garmin is similar. Runalyze is about as off as you are.

Maybe you're putting too much emphasis on weekly volume. M35 and I can run this with 50k weekly and 75k peak volume. Relatively confident I'd be able to sub 3 with weekly volume of 80k/100k peak.

Reading Faust in school left a lasting impact on me and an appreciation for the language as a tool of art.

I believe many are not even aware of the amount of proverbs coming from that classic:

Des Pudels Kern - the poodles core/crux of the matter

Gretchenfrage - the essential question

... And many more that I won't bother trying to translate.

I’m impressed by this project’s progress. It’s more than just a render library. Although they claim it’s 12x faster than ERB, but I couldn’t find their benchmark.

fidrelity commented on Show HN: I built a modern Goodreads alternative   kaguya.io/... · Posted by u/vasanthk1125

I'm definitely the target audience for this: I hate Goodreads and I still use it on a weekly basis.

A couple questions:

- where do you get your book data from? To my knowledge Amazon has a de facto monopoly on this and there's nothing more frustrating than missing latest or niche books, its covers, etc. or having wrong data/duplicates.

- do you plan on offering a migration path? I've got years worth of data on Goodreads.

https://blog.labsbell.com/blog/SkippiesPart2 selling 4.99$ shoes, strangely fun to see the inner workings of ecommerce. I dont understand how amazon sellers make any money.
fidrelity · a year ago
I love this and want to order a couple pairs!

1. Are the branded/not branded models the same cut? Since the angle on the pictures are different it's hard to judge.

2. Why do you not have more pictures of the shoes? Since those are probably impossible to try/return I want to try and avoid a wasted purchase.

3. What import taxes can one expect ordering to the EU?

I would go as far as to say it's a certainty there are things we can't detect yet... but probably not that many of them. Dark matter is funny because it's actually something that we can detect [0], at least indirectly but can't explain yet. But just like there are the EM and Higgs fields there could be countless other fields that don't affect our day to day reality in any way, but in that sense they might as well not exist.

Then you also have to accept that you're not talking about objective reality in any way but isolated to human experience and limited by our cognitive and experimental abilities.
