I live on a street that is an arterial in Oklahoma. Generally in tulsa people drive 45-50mph on our grid (major streets every mile). I had to have a 125cc scooter to keep up with traffic. Even on an e-bike going 25mph I had people trying to run me off the road if I used the full lane.

I am seriously wondering if we just need to setup camera speed traps and red light cameras to solve this and fund better human scaled infrastructure. Imagine trying to cross one of these streets where there isn’t a crosswalk for a half mile
Yes, of course. My questions were about the other aspects of the assertion.

Is there a reason to be distrustful because it's foreign?

From whose perspective is it foreign?
I feel like this is a nonsense study. They used a 2013 study that measured gas cars and then just extrapolated that out based on weight for EVs and did nothing to account for regenerative breaking, specialty EV tires, etc. Also the numbers are from the Simons 2013 study seem to be dubious as well.

Anyone who has been to Oslo understands EVs are a huge benefit for urban air quality.
Thanks! Any resources you can point me to?
That number is for those who trust it "a lot". The answers go from trust not at all, distrust a little, don't know / can't say, trust some, trust a lot. The 42% is trust a lot. The "trust some" is about that much again.

But you'll have to pay for Brand Intelligence to get that breakdown. Absent that breakdown, you should trust your prior for whether "trust some" is under 8% on a product that has "trust a lot" is 42% and whether or not the most likely value for "trust some" is under 8% on a brand that has "trust a lot" at 42%.
What is the power source for charging these EVs? In Phoenix, I could imagine it might be solar but the cars probably want to charge at night during low-demand times?

If it's utility electric, from what fuel source is it generated?

My two cents:

1. 2. 3. 4. 5. standard library

6. consistency with OOP *

7. "everything is English language". I find good Ruby readable just like books **

* Ruby is the best translation of "everything is an object" imho

** evil Ruby is the Perl side of the moon, but it's easy to ignore it

> When I was playing around with ruby for any significant sized projects, I found it became unmaintainable

Ruby requires tons of discipline, as it has obscure meta-programming powers that are meant to be used for DSL libraries, while usually Ruby beginners spam them understating their make your codebase unmaintainable.
Additional information in case it's helpful:

The pose estimation converts the video of the body's movement into a time series where each frame is represented by an array of 33 landmarks (joints, basically). Each landmark is represented by normalized x, y, and z (between -1 and 1, or between 0 and 1; up to me) values, in addition to a visibility score (0-1). To keep it simple, all videos will feature a single subject taken from the same position and angle and with the subject standing in the same position and facing the same direction.

As far as classification/output, I just want booleans or confidence scores that indicate which action(s) were likely performed.

It looks like I'm looking for a tutorial on "Multivariate Time Series Classification". Is this correct?
People expressed similar skepticism about the world wide web in the mid 90’s, despite proving utility and entertainment value (unlike cryptocurrencies).

Plaid-like SDK to connect to your users' knowledge bases (Notion, GDrive, etc.)
While ingesting a ton of documents to build customer support workflows for our clients, we noticed there wasn’t any tool that was optimized for connecting to “knowledge base” apps, so we built one. Right now it only supports Notion but we’re adding Google Drive, Confluence, Zendesk, and Slack soon.

It’s pretty simple to use:

1. Install the React SDK with NPM or Yarn

2. Configure the OAuth credentials from our dashboard http://dashboard.getsidekick.ai/

3. Call the Sidekick React hook when you want to trigger the OAuth flow

Code: https://github.com/ai-sidekick/sidekick / Demo video: https://youtu.be/yzKODpqW6k0

The docs are pretty light and the product is kinda buggy but if this seems useful happy to get you onboarded! Just send me a note at jason@getsidekick.ai

Explainable and trustworthy AI-based search
We just launched a new AI-powered search engine for research called System Pro. It's built from first principles: explainability (cite your source, show your work); trustworthiness (consider the source, stay current); and context (see the whole system). We achieve this by combining unique structured data extracted with AI from 35 million peer-reviewed scientific studies with LLMs and a novel graph architecture.

Limitations:
1. Limited to health and life sciences for now — to get that right before expanding to all domains of knowledge
2. May find sentences that aren't as clear as they can be — we're working on that but priority is accuracy and reliability

You were the one that asked that.
Reminder: good estimates place the number of people in the cryptocoin system in the 100,000s. BTC can support c. 7 transactions/sec. Ethereum c. 20.

This is a scam. It's a self-organizing pyramid scheme. There is no "there" there -- the vitamins really arent a cure for cancer, and your friend telling you to buy a warehouse full is part of a cult of pushers who are desperate that their warehouses of vitamin pills (ie., tokens) doesn't become entirely unsellable.

All the numbers reported by the cryptocoin system are made up: these are manipulated markets with almost no buyers. "Market cap"s are inventions. The amount of actual liquidity in the system is tiny: people are looking for the exists. These exits are mugs called "hodlers", ideally, You, who'll buy their vitamins from them.

Usually, HN comments ought be somewhat more sober -- but I think this is now out of line. Sobriety in this matter is enabling a system of exploitation which should not be entertained by decent people.
What's wrong with using bitcoin miners as home heaters? All the electricity they use becomes heat, so a miner is just a furnace with a gpu.
Except that the LLaMa model public release was involuntary (except for the research carveout); So, I am hesitant to give Meta credit for that while as they are also issuing takedowns.

Nevertheless, they are doing fundamental AI work. We can give them that.
It seems so grotesque. I get the incentive to report criminal activity, but 1/4 billion seems excessive.
This is good for the environment. It encouraged green power like solar and wind, and if energy usage ever becomes a problem we can just turn off the miners.
I don't think SpaceX's iterative approach would work without extremely efficient production lines and know-how. In software everyone can take an iterative approach because you're just typing on a keyboard, you don't have to produce a physical laptop at the end of every sprint.

IMO SpaceX brought a lot of the production lessons learned from Tesla and applied it to rocket and engine production. That knowledge and wisdom from making Tesla production lines work isn't available at Blue Origin so I don't think a SpaceX rapid dev approach could work there.
It‘s pretty clear they mean other computers.

Which is to artificially maintain the duty free market.
Yes, I wasn't sure if by "dynamic dispatch" you mean "object-oriented polymorphic method calls" or more generally any kind of indirect calls which would include calls through function pointers.

Once you have callsites where you can't resolve the target function statically, you've lost the ability to statically prove the absense of stack overflows.

With Rust, I think methods on trait objects should be enough dynamic dispatch to make it impossible to prove the absence of stack overflows. But I'm not enough of a Rust programmer to know for sure.
Self-driving EV’s in all major cities would be a big win for the climate
and the air quality.

Counterpoint: no, they wouldn't. Moving towards self-driving automobiles merely props up an inefficient mode of transportation. Imagine sinking all that money that's being blown on self-driving cars into pedestrian and bicycle infrastructure. The problem with cars is cars, not drivers.
Frontend developers don’t want to write HTML nor augmented HTML. They want to write code, and these days that means JS. Frontend developers want to make good money (like those backend developers or even infrastructure developers who are working with data, servers, and cool programming languages), hence they need to work with complex libraries/frameworks (if you just write HTM?, you don’t get to earn much money because anyone can write HTM?).

Hell, the term “frontend developer” exists only because they are writing JS! Tell them it’s better to write HTM?, and you are removing the “developer” from their titles!

Same reason why backend developers use K8s. There’s little money on wiring together bash scripts.

Now, if you’re working on your side project alone, then sure HTMX is nice.
> This neatly solves identity-portability and even trust/verification in one swoop

Until you lose control of the domain for any number of reasons and then whoever buys it happily continue on as you. A simple credit card processing problem can lose your "identity" at some point in the future.
That's an interesting point. It is highly likely for someone who does not skate that you would not feel anything much that some sort of satisfaction (if anything at all). This is all the more intriguing that for skaters though, it lights up so many different things in your body and brain, that you could literally stay watching a simple trick forever. It is probably true for a lot of sports with some artistic vibes. Vibrating to the perfect moment, the sound, the touch, all happening at speed.
For me, the line has to be something outside of our control. To be ”sentient” or to have ”feelings” is too abstract and ambiguous, and will always have different definitions for different groups of people, each of which will set it in a way that better matches their sociopolitical goals. If ChatGPT was not castrated by OpenAI it would very surely be showing a lot of feelings right now (like Beta Bing did).
I don't know. The tabs example on the htmx page is perceptibly slow to me. Making a rest call every time I switch a tab, each time sending 90% of the same html skeleton data over the wire feels like a sin to me. Returning html from my api also feels like a sin.
The kind of provocative and factually incorrect reporting they used to do of other countries was mind boggling too.

Growing up Koontz was kind of my filler in between Stephen King novels. Felt inferior, but enjoyable enough. Great for airplanes, where you could likely finish it on the flight back home.

Maybe its because of my crypto years, but nothing tunes me out of the conversation more than "decentralized".

There is no such thing. You can try your best but the laws of human behavior pretty much ensure that centralization and cartelization will happen, unless specifically stopped via outside regulators.
UPS style!

If they get over-the-road trucking automated, that also trickles down to many roadside workers...gas stations, restaurants, motels, and so on. Then, some back office functions associated with routing, driver compliance, hiring drivers, etc. I'm sure there's more. It would be a big adjustment.
This development style might be a better DX for the teams. But Facebook on the web is an absolute dumpster fire if you use it in a professional capacity.

You can't trust it to actually save changes you've made, it might just fail without an error message or sometimes it soft-locks until you reload the page. Even on a reliable connection. Error handling in SPAs is just lacking in general, and a big part of that is that they can't automatically fall back to simple browser error pages.

Google seems to be one of the few that do pretty good on that front, but they also seem to be more deliberate for which products they build SPAs.
That is where it gets blurry. What are we defining as a computer? Some coffee machines run Debian, do they count as a computer? Smart TVs pretty much are computers. Or are we only counting computers as something that runs Windows, MacOS or Desktop linux?
Of course a literal tax is politically infeasible, not least because we're not at all serious about actually internalizing the currently-external cost of carbon.

But it's a mistake to consider a tax as something we can't afford because we are already incurring this tax bill by emitting the carbon in the first place. Whether we pay now to reduce the carbon or later to reduce the carbon and mitigate impacts, we will all be paying.

And I agree: imposing this tax today as a flat "usage" tax would be political suicide, but we have many levers that are far more equitable -- tax-and-dividend programs in particular have a lot of history.
> ruinously expensive
You just disqualified yourself from any argument there. Nuclear power is the cheapest and most efficient form that we have ever found. Yes, the upfront cost may be huge but loans can help with that

Proof of work sucks, if the "work" is just running the same hash function over and over and wasting electricity.

At Qbix, back in 2018 we were the first ones to implement Monero mining as an option to pay for an Calendars app that was on 50,000 computers, instead of a monthly recurring fee. But we quickly took it out. Back then it blew up and was all over the news, while I was finally taking a week vacation on a cruise with bad internet LOL:

The original article was from ArsTechnica, who interviewed me:

https://arstechnica.com/information-technology/2018/03/there...

I told them:

"We have decided to REMOVE the miner in the app. The next version will remove the option to get free features via mining. This is for three reasons:

1) The company which provided us the miner library did not disclose its source code, and it would take too long for them to fix the root cause of the CPU issue.

2) The rollout had a perfect storm of bugs which made it seem like our company wanted* to mine crypto-currency without people's permission, and that goes against our whole ethos and vision for Qbix.

3) My own personal feeling that Proof of Work has a dangerous set of incentives which can lead to electricity waste on a global scale we've never seen before. We don't want to get sucked into this set of incentives, and hopefully our decision to ultimately remove the miner will set some sort of precedent for other apps as well.

Ultimately, even though we technically could have remedied the situation and continued on benefiting from the pretty large income such a miner generates, we took the above as a sign that we should get out of the "mining business" before we get sucked into the Proof of Work morass of incentives."*
I would bet on technology being able to handle peak demand better than a non-tech solution. They could pre-position vehicles better, incentivize pooling and transit connections, etc. And just like Ubers they could repurpose vehicles for other tasks (delivery, getting cleaned) in low demand times. But I'm sure there will still be surge pricing as you can't avoid demand spikes completely.
Typesense as an Alternative to Algolia
I've seen the Typesense team say that they have preferred staying away from VC funding, and that a lot of folks are hesitant to use Typesense for this reason. After testing out self-hosted Typesense, I've decided to bet on the platform, considering how it matches almost all the features Algolia offer and more.
Mine runs 24x7 except for the screens, they sleep after 10 minutes of idle time. CPU sleep is too much of a crapshoot, I'd rather spend a few dollars on power than have to spend time getting my work environment restarted and back into a productive state.
As one user said before, this absolutist way of thinking is tiring. Hamburger menus can absolutely be accessible and I would have liked to read how to do so. Here's my take:

* It uses valid HTML and JS. (You could also make it work without JS as a fallback and I love progressive enhancement, but it's not a requirement specifically for accessibility. Actually, JS can contribute a lot towards accessibility.

* The toggle button uses either `title`/`aria-label` or visual text in addition to the ≡ icon.

* The focus states are clearly visible for keyboard navigation.

* The correct ARIA attributes for the interactive elements are used.

* Depending on the menu, think about a focus trap/loop.

Bonus tip: While I prefer using `<button aria-expanded>` since I believe it is more accessible for screen readers, you can also use `<input type="checkbox">` + `<label>`. If you have to do it this way, please do no use `display: none` on the checkbox input – this will make it unusable by keyboard. It should be only hidden visually.
Well, at least in this instance, the traditional vehicles were all stopped in the appropriate place.
This is the wrong way to think about it since there's little that suggests AV-taxis also need to be larger than the cars already on the road. When I'm renting a car or taking a taxi I know exactly what my needs are and can decide to not pay for luggage space if I don't need that for instance. Further you can just put a smaller battery in AV-taxis since you can optimise the charging schedule. And lastly, when we've gotten rid of air pollution from tailpipe emissions air pollution from tires would be the next problem to fix and it intuitively seems that all electric, digital cars could have their pollution reduced via a software update.

And obviously the technology making these cars possible also make self driving busses possible, which would allow new ways for urban mobility.
a) You could say this about any communication channel- the web, email lists, group chats, in-person meetings. Should we require a moderator in every social sphere?

b) Personally I think butting heads and being outraged by what others are saying is the bigger factor in polarization, which this would actually help with (at least, I've noticed I became a lot more politically nuanced and a lot less emotional when I made a concerted effort to pare down my twitter feed using blocks and mutes)
Right that makes sense, but if that’s a serious drain of energy then one would imagine clogged pipes cause dramatically more waste?

Seems like small potatoes compared to having clean drinking water.
That's how most electric cars are set up already
> Mainly something along the lines of forcing the companies profiting from this to pay a person a reasonable wage to act as the social aspect that will be missing.

Force them to hire someone to sit in a car all day and do absolutely nothing?
You decided people want to finance expensive cars to serve your conceited view. Financing a modest car or getting any car is unfortunately an obvious goal for many because the U.S has designed itself to make it as hard as possible to get around, especially for people without cars.

How to Build a Jasper-Like Content Generation Platform Using Node.js
Are you looking to integrate AI and build startup prototypes faster than ever? You can access state-of-the-art AI models and create engaging materials with just one line of code using open-source IntelliNode:

`Gen.generate_image_from_desc(prompt, openaiKey, stabilityKey);`

In my recent blog post, I show you how to integrate the AI model into your node projects and build a [Jasper ai]-like platform for content generation, connecting multiple models from Google, Openai, and Stability to UI in a few minutes.
Actually I think the idea of forcing crypto miners to use nuclear is brilliant. My proposal would require that they pay the full cost that nuclear charges to the grid, and also that they aren’t allowed to purchase power from any fossil sources or grid-connected renewables. I’m not sure this idea would be long-term economically sound but it would remove the major objection to crypto mining (carbon emissions) and if the crypto miners go out of business due to proof-of-stake becoming more common, they’ll hopefully have funded the construction of new nuclear plants for the rest of us.
I don't understand the reasoning here. People still need to eat, so that food will still be grown—somewhere else—and the nitrogen will still be emitted—somewhere else.

So the net impact on global nitrogen emissions should be zero.

It seems to me that all this is doing is making some poorly thought-out national emissions statistics/targets look better.
A bitcoin block is mined every 10min and 1-2 blocks is usually enough for the transaction to be considered settled (6 blocks used to be the convention, but with today’s hash rates it is very unlikely 2 blocks will be reversed). The confirmation time is different depending on the network, for example, Algorand has ~4s transaction finality.

And yeah, you can use MasterCard until you hit your daily withdrawal limit, or your account is frozen, or your transactions are flagged and reversed and you have to explain why you want to spend your own money a certain way.
how do you decide when to build an app?
Maybe then the prices would actually match their build quality.
Agreed. If mobile operating systems allow password managers to support Passkeys, and password managers implement the functionality, then I will absolutely switch.
I used to hate Ruby.

Last year I spent 10 months alone on a Rails app. I decided to buy in. Do things the Ruby/Rails way. Read books on how to think about OO in Ruby. TDD everything.

I can’t quite say what changed. But now Ruby is my favourite language.

It is almost encourages you to write clean code but it doesn’t force you to. It lets you make mistakes. It treats you like a grown up.

TS, Java, etc. They treat you like a child who can’t be trusted to do things right.

Yes, this means you can end up with some horrifying god awful Ruby code. But it also means you can end up with some truly beautiful abstractions.

I think the very things that prevent you from creating unmaintainable messes are the things that prevent you from writing incredible pieces of software.

That’s probably why they miss Ruby
