Bridge jumpers are self selected group of mostly physically healthy people suffering from the mostly temporary/treatable mental health issue of depression. I think almost nobody would argue that depression should qualify you for assisted suicide. Also, jumping off a bridge is probably the most terrifying method of suicide available. It's practically suicide-by-torture, yup, you're gonna regret that. It's a very, very different scenario than people who are in unrelenting agony and almost certain to die in X weeks/months, saying goodby to their families, going to sleep, and not waking up again. Do you think if you gave them a placebo, let them wake up again and asked "are you _really_ sure about this?" that many of them would change their minds? Probably never been done, but my guess is you'd get very few changed minds.
>and how few governments have slipped into totalitarian hellscapes

Just because it's improbable doesn't mean we shouldn't protect against tail risks. Not taking meaningful tail risk protection is why we're in the covid-19 problem we are now.

>I'm not as worried about this as you are.

I wouldn't want to be presumptions of your background, but have you talked with many people from countries where they or their parents were victims of state bullying via secret police that kept files on them?

I don't think what we're talking about is any different in the long run.

>The system I outlined would work XX% as well if it were entirely optional and if it were managed by independent agents.

I'm actually not opposed to a temporary system of tracking like this in order to stamp out coronavirus. However, it needs to have iron-clad provisions in law to make it time limited, along with laws that mandate that independent international observers witness data audits and subsequent destruction of said data. Unfortunately, when governments legislate provisions, they're usually in the form of "we promise to be very good" platitudes.
I'm working on a cross-platform markdown editor written using Kotlin multiplatform: https://github.com/saket/press.

The plan is to start with an Android app and a macOS app to solve for my personal use-case and add more platforms in the future. The primary motivation was the lack of good markdown apps that sync between Android and macOS. Bear notes is the closest, but they don't have any plans of creating an Android app.
Ask HN: Feynman's Lectures in other disciplines?
I've been reading through The Feynman Lectures on Physics and I am really enjoying them. It almost reads like an internal conversation one would have with himself, while trying to understand a subject. It's logical, and detailed.

Do you know of similar study materials / lectures in other subjects: math, chem, bio ?

I understand they are obviously not going to be by Feynman, but I am looking for a similar approach taken by people in other disciplines.

Thanks!

People need bigger houses for other reasons too, including a growing family, having space for gathering with their friends and community, for their hobbies etc. And I’m not talking about a luxurious McMansion, just something bigger than a $3500 1 bedroom apartment where you can’t have a friendsgiving with more than 4 guests.

Being able to work from home long term means not being tied to ultra-premium land for your private space. Not eating up the externality of your company deciding to hire 10s of thousands more workers in your already crammed city, not being forced to choose between the externality of longer commute time or inflated, subpar housing services.
You would bet money that the insurance would cover it instead of finding a way out of it? What makes you so sure about that? There are examples of homeowner's insurance not covering issues caused by renting on AirBnB, so I would be surprised if motor vehicle insurance was any different.
What decisions were made years ago? I honestly have no idea what you are talking about.

A lot has changed in a matter of 3 months. Decisions are constantly being re-evaluated with new information. I was simply opining on how something like "an increase in working from home" might actually have larger societal impacts.

This article suggests people might move away from expensive places like Silicon Valley. I am suggesting there is another angle, the amount of space people have available at home to actually perform work. It shifts the burden of finding a work station off employers and onto employees. Does a one-time stipend of $1,000 cover that? Probably not for many people.
Known as "cancellation of indebtedness income." https://www.irs.gov/newsroom/home-foreclosure-and-debt-cance...

Foreclosure of non-recourse loans does not trigger cancellation of indebtedness income. Instead, it could trigger capital gains.

Tyler, this is really innovative. The VC model needs rethinking, aligning more with founders, and along the lines of what you're doing here. Your mentor model works great also.

As a founder of a company that has gotten to 8 MM users across 95+ countries, and $1M in revenues, and
there is a lot more I can tell you in a private conversation. We've applied to VCs along the way, but the model is not always aligned with companies like ours, which make revenue from the beginning rather than hockey stick growth and zero revenues.

One of the major reasons is that these kind of startups often need small amounts to get to the next level, but the due diligence of a VC sometimes costs more than that amount. If there was a "roadmap" model that VC would fund, say, $10K to get to the next level, then $20K, etc. and if it falls short, then they have to seek another such VC and syndicate. A bit like taking on lenders except it would be more along the lines of your Shared Earnings Agreement + Equity. Everything would be clearly spelled out, and rather than spending tons of time on due diligence, it would just be about a history of execution.

PS: We filled out your "regular" application in early April, please check email from @qbix.com ... would love to talk next week.

PPS: If you're a startup founder chime in and add your 2c, does your own experience in early stages resonate with what I've said? That if you were able to break down what you need to get to the next level, in $10K and $20K increments, with a second or third chance on slightly worse terms, you'd be happy to be funded in that manner, and work hard to make serious progress and document it.

Benchmarks are subjective, but all benchmarks show Ruby as slower than compared dynamic languages. The relative speed difference is different per benchmark, but across the board Ruby is slower.

It fundamentally has to be slower. Ruby is the most dynamic of the dynamic programming languages. And the community has embraced metaprogramming, making it every more dynamic. Especially on webservers, you'll be executing hundreds, sometimes thousands, more lines of code than other servers, especially in a mature system.

Is it "slow" enough to matter? Probably not until you get to a medium scale. Everywhere I've worked, we've had to on average double the hardware specs for Ruby servers to make them as performant as other dynamic language applications we run. Not the most expensive thing in the grand scheme of things, but there are entire cottage industries of magically tuning Ruby and Rails that you don't have to worry about with other systems until much larger scales.

"If they can only work five hours a day"

I appreciate the sentiment, but five hours?! That's your example of an acceptable low level of performance for someone working from home with a child with no possibility of childcare?

I'm splitting card of my toddler with my spouse, and on my BEST days, I get 3 hours of actual work done. 1.5 is more typical, and that's only because the toddler takes 2 hour naps.
This is constantly brought up on HN in the WFH threads.

Your employer cannot arbitrarily reduce your salary. The reduction has to be agreed upon by the employee or the employer has to terminate employment and rehire to reduce salary.

Very few big tech companies will update salary for a intra country move. It seems to happen most often when an employee relocates to a new country rather than a new state. This is because the new country requires a different work agreement and must follow different labor laws.
Thank you everyone for your feedback, it's very motivating to see that so many people find this project interesting. I might turn this into a Show HN soon, once the site fills up with some interesting predictions.

On the technical side, the logs show over 6600 unique visitors in the last 12 hours, with over 1100 of them (and 18k requests) during the busiest hour. I know that's not too impressive, but it's still good to see the basic VPS running the server didn't break a sweat (load average peaked at around 0.1).

In the mean time feel free to post content you're interested in, and also contact me (e-mail is in my profile) if you have any feedback. Thanks again!

I would disagree, having been on both sides of this half a dozen times each.

When you write front-to-back, you don't get an immediate sense of what the deeper relationships and nuances of your data models are going to look like. You're designing for what you immediately think you want to see.

This approach can work well, until you run into things that end up being a lot more difficult to implement behind-the-scenes than the data you just expect to appear on the page in front of you.

Personal experience/preference, but the thing that has (almost) never led me wrong was doing a walkthrough of the domain of the application, and then thinking about what the client-side pages and functionality are going to look like (page-by-page, user stories), and then implementing the backend. Finally, wire up the backend to the frontend mockups/design.

For more complex systems, there are things that need to be ironed out in their entirety and have their modeling/relationships, and functionality proven on the API side of things before you decide to start writing UI elements for them.

On the flipside, having worked on projects where there have been major, multi-month setbacks, it was nearly always because the models/domain weren't well thought out and it needed major components to be re-worked (either UI or backend) before we could proceed.

I do all the maintenance on my car. I have learned 95% from watching other people do it on youtube. The other 5% is from forum posts and a repair manual.
Interesting, thanks for the reading. I am tempted now to get a higher salary in an expensive location, work on-site and then remotely from that location, then quietly move away without telling anyone. As long as my hours are the same and work quality don't change, nobody should be the wiser.

Who knows what they intended? It's probably not very nice to load them up with extra spam just because you're lazy (? I mean really, what are you gaining here?)

I own a domain that is similar (in a "1337" way) to the domain of a CRM SaaS operation. At least once a week one of their customers signs up using my domain in a throwaway fake email address. I find it extremely frustrating. Because of their architecture and mine there is no easy way for me to filter these messages so I am often stuck with the spam in my inbox. I don't hold a grudge or anything, but I wish people would think before they fill in someone else's perfectly valid info into a form they don't want to give their own info to.

Pretty good representation of my work flow. I generally save the details (permissions, validations, test coverage) for the end of the process, once the architecture is more solid.

Some projects I spent more thinking on, but especially where specs and design are more vague, I approach it from front to back
If you haven’t already, try Capture One. It’s so much faster than Lightroom and, at least for my needs, has much better functionality as well.
Agree those are also good.
Well, you surely could do this via some proxy setup. But in that case you could also simply rely on LetsEncrypt directly; them going away is as likely as your average hosting provider.

Now, of course that's an item on the maintenance list if you're hosting the web page yourself, but as mentioned above: You still need regular updates, having certificate renewal on that list doesn't make any noticeable difference.

> The legislature passed a bill that granted this power to the executive in past decades.

No, the explicit holding in this case is that the executive has not been granted this power by the legislature.
I think it's the other way around. The architecture was being limited by their fabs ability to yeild large chips and in the absence of any CPU perf pressure from AMD the natural push would lean more towards increacong graphics performance in order to push more pixels. As in I think Intel probably had the same yeild issues as everyone else ~10-32 nm but only Intel had the high margins small chip volume to make it profitable to ramp until Apple and TSMC happened.
Will this program terminate?

> while(true): do nothing

A computer cannot tell you that this program will not terminate, short of memorizing this specific set of instructions as a "non-terminating" program.

I can read it and know it will not terminate, but I could not define to you how I know that algorithmically. Despite that, I know it will not terminate, and so does any programmer. Just because it cannot be expressed algorithmically doesn't mean we don't possess that capability.

This is my point about consciousness: there is some aspect to it which cannot be articulated, hence my skepticism that computers will ever become conscious.
I built Logicboard: https://logicboard.com a tool for conducting remote programming interviews. It's like Google Hangouts + you can write/run code in over 28 languages.

It's kinda amazing how much you can learn building something new, I improved my Elixir, ReactJS and Devops skills.
The cybertruck should be able to do this "out of the box". It has a 240V output (though they did not reveal the amperage, it must be at least 30), so your house should not care whether it's running off a small generator or the truck, nor should the truck care whether it's running a tool or a house.

People have tried to estimate the truck's battery size from it's drag coefficient (via it's watts per mile consumption) and it seems the 500 miles version should have like 150-160kWh of storage. You can run your house for a long time on that.
This new version of Beaker took over a year to get done and is basically a ground-up rewrite. Team is here to answer any questions.
I thought for this the standard practice is fixed-point. Requires more planning and mental gymnastics but usually much faster and gives you full control of the precision.

Maybe this has changed from my DSP days.
Does IKEA do smaller-format stores anywhere? Even the "small" (relatively) IKEA in Memphis, TN is still a 270,000 square foot space-- close to double the footprint of the Costco next door, and two stories in a good chunk of the building.

It seems to me like it would be hard to scale an IKEA down-- the showroom side needs to be large because assembled furniture is large, and the warehouse side also needs to be large to stock everything (unless IKEA changes up their business model to do everything by delivery, but then they've lost their big distinction from all the other furniture stores around).
> see an interesting language concept, but it's not entirely here how that relates to the initial claim.

I didn't see any concept which wouldn't be practiced in PL design for decades. Yeah, they may not be widely known, but suggesting that "structural, nominal, and union" types are anywhere near any kind of "breakthrough" is just too much. If anything, the language seems conservative in its design rather than novel.

Hands-On with the Nvidia Jetson Xavier NX Developer Kit
SIMD works great for doing the same thing to multiple pieces of data, but it doesn't do the scaling up that I described.

I'm no chip engineer, so maybe what I'm envisioning isn't possible. In essence, instead of making 4x 64-bit cores you make 128x 2-bit cores and then some architecture on the die to select groups of cores to build a processor of the required size, execute some instructions with that processor, and then disassemble the processor back into a pool of resources.

So SIMD might be able to calculate two 16-bit sums on a 32 bit processor in one cycle, but the hypothetical CPU I'm describing will be able to calculate a single 128 bit sum and eight 16 bit sums in one cycle, at the same time.
With gas prices what they are and likely to be there for the next few years, now is a great time for Tesla to hit purchase price cost-parity with ICE vehicles. Hopefully this new battery can deliver on that promise. In theory, we could look at total cost of ownership and say that a Tesla is a good buy, but unless the sticker price looks good there are plenty that will keep buying sub-$2 gas guzzlers.
It's not that bad, actually.

When a product is really early - still being developed, basically - you want to control the number of users you expose to it.

Every batch of users will improve the product but it is unlikely that users will stick around beyond one or two uses.

So you drip it out to users in small batches, and "wait for me" really lends itself well to this.
Interesting how much analog architecture was used. Today everything is processed digitally with ADC/DAC at the edge. Those old 8-bit MHz-class processors and memory chips lacked the horsepower to synthesize sounds without disrupting gameplay.

Missing IMO the number one lesson all developers should learn:

Learn how to name things.
The Chinese room argument says that syntax cannot capture semantics since a man blindly executing rules to process Chinese symbols would not understand Chinese. But the man isn't the the system that is purported to understand Chinese. That's like saying the CPU in a computer doesn't have memory so your computer doesn't have memory. But of course that's wrong, other components of the system provide the function of memory. Using properties of the CPU to determine properties of the system as a whole is a mistake.

You might recognize this as the system's reply for which Searle has a response. But his response is insufficient to save the argument as it merely equivocates on what "the system" is. The system is the set of rules and the database of facts, some input/output mechanism, and some central processor to execute the rules against the symbols. The system's reply says that the man blindly executing instructions is not identical to the system that understands Chinese, namely the entire room. Thus properties of the man have no bearing on the properties of the system; that the man does not understand Chinese has no bearing on whether the system as a whole understands Chinese.

But the man is still not "the system" when he memorizes the instructions and leaves the room. The system is some subset of the man, specifically only those brain networks required to carry out the processing of the symbols. Importantly, these brain networks are different than what we take the man to be. It is true that the man doesn't speak Chinese, but since the system processing symbols is still not identical to the man, properties of the man do not bear on properties of the system. So still, the fact that the man blindly executing instructions doesn't speak Chinese does not entail that the system doesn't speak Chinese.
Well, if the only thing stopping you is being ashamed, I can make a deal with you...

You put it on Github, and I'll review the app and suggests code improvements (probably not amazing since I don't do iOS that much, but I know some Swift, and a lot more experience with Go, Java, JS, etc.).

Up to you, but you should never be ashamed of the code if it works. It got accepted to appstore, it's good enough ;).
