I found this archive while researching a book titled Six Hundred Receipts Worth Their Weight in Gold [0]. My first thought was that the book itself could be a great resource for anyone working on a crafting mechanic for a video game - it covers cocktail recipes, but it also has recipes for varnishes, dyes, medicines, etc. Enjoy!
Huh, I wonder if anyone's tried to validate this approach again now that we have LIGO (and presumably more precise equipment?). I know very little about the physics involved here, but the articles I found about Weber bars don't cite disagreement about the theory underpinning the experiment, so I'm curious if we expect a detectable effect with our current understanding?
I also know very little about manufacturing Weber bars, but I could imagine it's cheaper to build 100s or 1000s of these and perform signal processing on them than building another LIGO. Or Weber bars in space?
If you look at the lengths LIGO had to go to in order to eliminate background noise to even be able to theoretically detect gravitational waves, it seems very unlikely that a comparatively crude technology from the 80s could have achieved the same things. Like modern lasers or squeezed light states, which were mostly theoretical back then. If I remember correctly, Weber's device was claimed to show a huge amount of events per year, which would indicate tons of GW sources in our neighbourhood. LIGO and the rest of modern astronomy have since disproved that.
Sometimes noise turns out to be signal (see developments leading to Cosmic Microwave Background [0]). At this stage in gravitational wave detection is it well founded to consider noise as noise instead of information we cannot yet understand?
Noise always has different sources, and when you eliminate noise you should always be conscious of the source. There should be a gravitational wave background analogous to the CMVB. Detecting it would be a sensation.
The creator of this app, Nick Kallen, has a nice YouTube channel where he talks about some of the behind-the-scenes work on the project. I think his video comparing geometry kernels [0] was posted to HN a while back, but it's worth a watch if you're curious!
I learned about WebTV while writing essays for my college applications more than ten years ago. I had stumbled on this memorial site[0] for an engineer at WebTV named Jos who passed well before his time. The site includes some of his college essays[1] as well as some other bits of writing like his guide to OOP programming[2] (complete with Spanish and Portuguese translations !). His writing style and sense of humor have stuck with me for years and years now, and I still visit the site to have a laugh. Seemed like a very dynamic individual, and I'm grateful to his family for keeping his memory alive.
I came here curious if anyone would point this out. I was surprised to see the post describing UTC + lat/lng as a common practice in APIs without discussing this quirk. E.g. to your point, China's border with Bhutan is politically "fuzzy". Bhutan uses UTC+6, and Beijing Time is UTC+8. Weird that the post acknowledges timezones are a political construct but misses the fact that borders are too.
I’ve been using shadcn’s UI library lately and have been loving it. It’s distributed as a CLI that you use to vendor in pre-baked implementations of Radix UI components using Tailwind. Once they’re in your repo, you customize them as you want. Great for scaffolding a branded component library. React-only right now.
I once mentioned Desmos to a college friend who was teaching high school math. This was the first and one of the only times I’ve seen someone express true glee about a software product. They literally shouted, “I love Desmos!” at the dinner table. Kudos to the team for building a product that teachers love that much. Teachers need all the help they can get.
I’m so curious about how their graphing calculator and their geometric construction tools work. I’ve spent marginal amounts of time researching their stack, and it appears to be custom software. If anyone’s familiar with writing about how these systems are built (particularly the display side of things), I’d appreciate some links or titles!
Desmos is a true gem. It took me a while to understand how great the graphing calculator really is. There is also GeoGebra, which has similar functionality and I always thought it is just a rebranded Desmos, but they seem to exists independently.
GeoGebra is actually way older (about 10 years?) and has been a master thesis.
I didn't know that it has been acquired by Byju's.
https://en.wikipedia.org/wiki/GeoGebra
I was at school with the CTO of GeoGebra in the 80s. He released his first geometry app in the early 90s, but I don't know if the current product owes anything to his early software.
I wrote FooPlot around the same time (2007). Ad revenue supplemented my PhD salary by quite a bit, though later on I couldn't keep up with Desmos as 1 person. The website's been down since AWS phased out EC2 classic instances and I was lazy to move it. But the code for the core library is still here, including the equation parsing which is quite similar to TFA. It's written in 2007-level JavaScript, so this could probably be a lot cleaner now.
Wonder how the author here would feel about surgeons going on strike scheduled intentionally after beginning open heart surgery on a loved one?
This is a silly comparison. Concrete trucks don’t have beating hearts - they’re just property owned by the business. It’s important to recognize life as distinct.
Physicians take the Hippocratic Oath, and they otherwise generally care about the well-being of their patients. Also, it is illegal to strike at a health care facility without first giving 10-days notice (to plan how to continue care). I’ve talked to residents organizing at Mass General Brigham, and (though they aren’t planning a strike) my vague understanding is that the logistics of striking in health care are targeted more at paperwork rather than holding up care (e.g. provide the care but don’t sign the notes so billing can’t commence).
I recommend reading more about how organizing in health care works - it’s complex, very topical these days, and I think it’ll show you that folks tend to care for one another. Too easy for Silicon Valley edge-case thinkers to reach for ad absurdum armchair arguments like “what if a doctor let their patient die on the operating table because they want more money” - that’s not where their heads are at at all.
It’s also incredibly important that quality of life improves for health care workers. Med students are 3x more likely to die by suicide than the general population.
While it may not be an apples to apples comparison and certainly exaggerates the impact (a human life vs property), it describes the mechanism of the intentional destruction of property in this case pretty well.
Even the NLRB states that a strike may be considered unlawful if it deprives company owners of their property. Timing the strike to intentionally destroy company trucks seems to go far beyond the act of the organized withholding of human labor.
No, I am not confused. One is murder and one is intentional destruction of property. Both results are due to intentional sabotage by the actors involved.
Doctors… don’t murder folks (I mean, yes, this has happened, but not as a strategy of a strike). It’s a nonsense hypothetical created to make striking sound absurd. I’ve already described in general terms how striking in health care works. Walking out to strike mid-open-heart surgery doesn’t happen - it doesn’t benefit the doctor, and they would be liable for their actions (and for violating the 10-day notice, presumably). There are legal differences between property damage and taking a life, so the comparison isn’t particularly useful.
I draw a line at trying to compare property damage and homicide as if they stem from the same “mechanism”. There’s no analogy to be made there. The striking workers didn’t kill anyone, and it’s insidious to float “how would the author feel if a striking doctor planned their action to kill someone” hypotheticals because murder and property damage are not united under some definition of “sabotage”.
Like, what’s the useful takeaway from the comparison? Cement getting left in a truck is like losing a loved one? Really? Striking workers performing something like sabotage is similar to pre-meditated murder? Are these useful comparisons? I don’t think so.
> This is a silly comparison. Concrete trucks don’t have beating hearts - they’re just property owned by the business. It’s important to recognize life as distinct.
Okay, consider this scenario instead: you're getting an addition put on your house. Right after ripping the old roof off, the workers all go on strike, letting your house fill up with rain and snow.
Depends on the nature of the relationship with the workers.
If I’m employing them directly, I doubt there would be reason for a strike - what are they striking against? I don’t have a construction company. They’re either doing the work as contractors, and I’ll pay for it, or they aren’t doing the work, and they don’t get paid. IANAL, but I doubt it’s considered a strike if contractors skip a job or abandon a job midway through. Also, it’s important to foster a good relationship with your contractors and to make sure both parties agree they’re benefiting from the business relationship. That’s just simple good business.
If they are under someone else’s employ, the comparison doesn’t add up - the cement-in-truck didn’t cause substantial damages to the customer. (Maybe delayed schedule? I don’t know the details of the case.) What you are describing harms the customer directly. Talk to folks that are striking, and they will almost unanimously say they don’t want to inconvenience the customer. Rather more often than not they’re seeking to change the terms of their employment to benefit the customer, whether that’s more staffing, more safety, or more manageable hours to provide better service. These are folks working closest to the customer touchpoints, and I’m inclined to trust their knowledge of customer service more than management’s.
> Talk to folks that are striking, and they will almost unanimously say they don’t want to inconvenience the customer.
While they might say that, actions speak louder than words, and I as a customer have been inconvenienced a lot by strikes, e.g., when my car sat in the shop for over 2 months because it needed a part that ran out of stock and a UAW strike delayed any more of from getting made.
Looks great! I like the idea of focusing on highlighted regions at a time. I spent some time exploring similar form factors for learning the fretboard, focusing intervals and shapes more than the notes themselves (link below) - I implemented a two-step drag-and-release gesture with visual feedback for selecting positions on a mobile device, and I think it helps avoid frustrating mis-taps. Maybe something to consider for your UI as well. The additional modules look interesting! Bookmarked.
This is great. Thanks for sharing.I do have stuff in mind thats very similar but a bit of a different form factor. I havent tried your app on mobile so I dont know about the two step thing but I'm excited to take a look
Thank you for appreciating the app, its sweeter coming from someone who's built something similar. Also, btw, dont forget to sign up for updates to stay up to date on when new modules are released.
Cheers
