I wouldn't count on it, the current government have been giving Tfl a kicking on arguably ideological grounds (referring to our mayor, who I think on past statements would broadly agree with you). Bit hard to make such cuts and push improvements when you're on the rack.

> TfL is unique compared to other transport authorities in the world in that it is mostly dependent on fares for its income. This is largely down to the fact that the Government took the decision, in 2015, to remove TfL's £700 million annual operating grant from April 2018 onwards... The Government’s punitive approach to TfL’s financial future not only jeopardises London’s economic recovery, but that of the country. Ministers know that investment in London’s transport system creates jobs and generates dividends for the rest of the country

> So, you'll abandon this argument and concede the point? I suspect you won't, because my anecdote isn't enough for you, and those obstacles aren't sufficient proof, etc...

Are you trolling with this?

I'm asking if it can reliably do that. Of course I need more data than one person can collect. I am not being unreasonable to ask for more data than your personal experience. Most people with autopilot never saw this problem either.

And specifically I need to know about freeway speeds, because speed is an important factor.

There is plenty you could do to change my mind. If you link to something published by tesla or a government body showing autopilot and FSD accident rates by type then that would be more than enough.

> So basically you're sitting here and glibly demanding that this product be 200x safer than its competitors before you'll consider it acceptable

I'm not asking for a lack of fatalities. I'm asking for a lack of hitting stationary vehicle-scale objects on the freeway.

Do you think that particular kind of accident is responsible for a majority of fatalities, or something? My expectation is that it's a very rare kind of accident and I also feel like it's a good canary.

Also the freeway fatality rate is about 5.4 per billion miles, not 20.
Whats worse, some Google services work very suboptimally in Firefox, serving a simplified page or whatever.

I'm sure there are good technical reasons for this, but it seems suspicious.
I post to Facebook and Twitter using bookmarklets and i just made a bookmarklet to use newsproxy.ca to get around Facebook's news blockade in Canada.

These you posted are really great
tvalmetrics is similar to ragas for sure, and we really like ragas. tvalmetrics has structural differences as well as differences in the specific metrics when compared to ragas.

With regards to the metrics, we have an end to end metric that scores how well your RAG response matches a reference correct response called answer similarity score. Last I saw, ragas did not have a score like this as they focus on scoring RAG responses and context without a reference correct answer. We also have a retrieval k-recall score that involves comparing the relevance of the retrieved context to the relevance of the top k context chunks where k is larger than the number of retrieved context chunks. Retrieval k-recall is a good score for tuning how many context chunks your RAG system should retrieve. I do not believe ragas has a score like this.

Structurally, tvalmetrics does not use langchain, while ragas does use langchain. We chose not to use langchain for our LLM API calls to keep the code in the package clear and make it easy for a user to understand exactly how the LLM-assisted evaluation works for each metric. Of course, the drawback of not using langchain means that our package is not integrated with as many LLMs. Currently, we only support using Open AI chat completion models as LLM evaluators to calcaulate the metrics. We plan on adding support for additional LLM evaluators very soon.
There are builtin keyboard shortcuts in the YouTube player.

Shift+, or . for changing the speed.

They cannot be customized though.
For things you need to always run Grease Monkey seems like a prime choice. You could have your script run automatically for every visit to a nebula page.
There is an importance of knowing your worth and weight if you are loyal and subject to exploitation.

Just because you can get shit done does not mean it is okay for managers to dump work on you where others are failing to pull their weight. You will burn out and you will be resentful of those exploiting you.

Also with regards to monetary value, ask for the raises regularly and prove that your work leads to said results. You should be getting the maximum rewards and having your salary adjusted based on the competitive market rate. Apply regularly to remind your employer who you want to remain "loyal" to that they can lose you if they aren't keeping up monetarily.

There are very few people in the world who look out for your wellbeing if you are "loyal". They will not help make space for when you need to take time off, they will not advocate for your promotions/career growth if you're in a crucial role, they will not see the disparity of how much value you bring versus how much you're rewarded.

You have to advocate for all this yourself. Be loyal to yourself first.
Starship is awesome. It's the most capable and sophisticated rocket ever built. It's a major asset to the US military and its future capability. It has very significant launch safety issues in its current state. FAA enforcement is generally reasonable; they're professional and competent.

I don't know why this topic polarizes people to such an extreme degree.
> Where I live, there's islands which are not owned by anyone in the rivers. (Check your county's GIS map for which ones) You can just go camp on those, no problem.

Oh, you have to care about who owns the land in order to camp in the wilderness? Bummer.

https://en.wikipedia.org/wiki/Freedom_to_roam
>(NASA, Reuters, bloggers, authors, scholarly journals) still write and publish (including to social media), the viral content makers, a second tier of people who write about what the original author wrote about,

I like original primary sources for some topics and secondary sources for others. For programing topics, I'm ok reading the original papers.

But for other topics ... say "civil engineering" ... I prefer a "popularizer" like Grady Hillhouse's "Practical Engineering". His 15-minute presentations are the right amount of depth for exposing me to various city infrastructure topics. I'm not going to pretend I'd be interested in reading original scholarly journals from civil engineers. I deliberately outsource that to Grady. Hardcore engineers may complain that infotainment/edutainment is "shallow learning" but people have to strategically limit themselves to "shallow" explanations of some topics so they can spend more time to deep dive into other specialized areas of interest.

The "viral content makers" serve a useful purpose in the ecosystem to satisfy varying levels of interest. Therefore, a search engine that optimized for original academic papers instead of Grady blog posts when I ask "How does a city manage stormwater runoff?" -- would not be helpful to me in most cases. I dare say a "general" search engine that didn't put academic papers on page 1 of search results would be preferred by most people.
No longer true. Now they use the camera to verify you're looking at the road.

Also, we can drive just fine with two cameras and a neural net, no LIDAR.

In engineering, you don't add something unless it's necessary, not because "well we may as well have it."
That'd require:

1) regular spills of fuel, that

2) aren't burnt up in the air before they hit the ground and

3) are liquid, not gaseous, and

4) are hypergolic.

Boca Chica doesn't have any of those 4 requirements.
Zvi Mowshowitz also worked at Jane Street Capital and I found his take on SBF's rise and fall pretty compelling and detailed.

Interesting how SBF seemed to almost be running around in a sort of dissociative state. He was sorta aware that there was a whole world out there with consequences but he just completely ignored it. Screw the consequences, just kept doing whatever dumb stuff he wanted to do.
The lore building in it is really enjoyable to me.

It almost reminds of me Tales from the Loop, which is extremely slow but all about world building.
We wrote Puter.com in vanilla js and it's been pretty straight forward. tbh most of the complexity is coming from the backend rather than the frontend.
But will Web Components of tomorrow be the same as the ones today? I see that, in today's parlance, this is 3 core ideas. Custom elements, shadow DOM, and templates. I fully expect things to be added to that list as time goes on. Not the least because of so many obvious things that are not covered there.

To that end, the question will have to be if you can run the same web components of today on a browser of tomorrow. With the very notable fact that though you can't run components on browsers of yesterday, you can run that old jquery site on browsers of today.
I was looking at archive.org for some stuff that had been on a site of mine 20yr ago, just the other day. They had it once, I've linked to it before.

Today they only show a MS-IIS "404" page for those pages as "what we archived".

Which is quite strange as those sites never ran on IIS; those URLS could never have produced that page.
Far more? … <laughs in Union Carbide>
Off topic but I love how the Verge sticks to their bit that Bing is super horny.
Google constantly nags you to install Chrome whenever you first visit their properties. All of it is super annoying but I see Google doing it more than Microsoft.
I think you have an intuitive mental model of how it works, but don't actually understand it, or aren't able to explain it well.

This question is important enough that there have been papers written on it. I suggest you read https://pubs.aip.org/aapt/ajp/article-abstract/65/6/501/5300... which may strengthen your understanding.
Oh that’s interesting. Yeah 青 is used in Chinese as another word for green. I don’t know that it has any connotations of blue, but I did grow up in the US, so perhaps there’s nuance to that character I’m unaware of, or the character slightly changed meaning when made a kanji.
I felt their library catalog is lackluster compared to other streaming services. The contents I want to watch are usually buy, rent or with supplemental subscription. They have a reasonable tv shows selections but most of them seems to be Apple Original. Their movie catalog is very lacking, not sure if it is a specific genre (Horror) seems non-existent or require to buy, rent or other subs instead of including with Apple TV+.
Yes but you don't have access to Apple's database, and therein lies the problem. Apple might send you a receipt that itemizes these things, or it might not. If you're a business you're dealing with 1000 different Apples all of whom have different policies about how granular their receipts will be, each with a different mechanism for you to access those receipts, and each making receipts available at different times.

Meanwhile you need to do a reconciliation for your company at the end of every period (e.g. the end of every day, every week, etc.) and you don't have time to wait around for all those receipts to be collected.
Is this a joke? html and css as one big JS string?
thank you @simonw for all your writing about LLM's. also thank you for your blog in general, it's an amazing resource. also thank you for django. just, thank you!!!
As someone who's into more light-hearted fare...

The After Party is fun. It's a murder-mystery, with each episode retelling the same night of the murder in the style of a different film genre. Rashomon-y, but more about playing with genre than with strictly what was seen.

Mythic Quest is pretty well targeted for the HN crowd, insofar as it's a comedy set in a video game studio, and does a lot about software-dev culture.
The Verge has a long running joke that Bing is very horny.
It’s gen z for horny.
This is two gang bands fighting on the street, there is no good guy here. Google is so annoying trying constantly to push you to use Chrome when you visit their websites
> my real point that the unthinkable numbers from the video aren't actually unthinkable anymore because Tesla has a massive flee

Yes, I'm addressing that point directly, specifically the fact that this "unthinkable number" is misleading regardless of the number's magnitude.

Tuftianism is the only cult I'll ever be a member of.
There are also personal computers that have no browser options. Ostensibly, Microsoft and Google are competing here, just abusing the horrible precedent of first-party control.
When an old employer required us to use windows, I just built a Linux VM that was always set to fullsceen. Surprisingly they were okay with it, so maybe you'll have the same luck?
Not from Boca.
Boca is a testing grounds, since they aren't allowed to test elsewhere.
Cape Canaveral wasn't a super attractive location in 1950 either; swamps, hurricanes, a lot of mosquitoes, hot summers.

But, same as Boca Chica, it is on US soil, relatively close to the Equator and you can launch rockets eastwards over the sea. And in both cases, closures of the sea for launches don't disrupt important sea lanes.
You'd have to merge JavaScript and HTML to get htmx in any usage capacity. HTML is not a programming language, it's a markup language.
"Why didn't you switch to the obviously superior Firefox?"
If you read up on narcissism, you'll see why this is no surprise.
Rumour is that SpaceX was seriously considering Puerto Rico before it secured the Boca Chica location.
We should really just stick to anonymous stored value cards that can be recharged by cash. Forcing anything else is surveillance overreach.
I don't see why SpaceX couldn't launch from there even if it required some kind of special ITAR permission first. It's not like those haven't been made before if needed. SpaceX has launched EU spy satellites anyway and the US used to launch some satellites with Ariane 5 etc. Or am I missing something here? It just seems like it shouldn't be a big deal if SpaceX constructed a launch site in French Guiana or some other country that participates in American space programs.
Methane is gas, liquified methane spills evaporate and go to atmosphere. Not perfect, but no land poisoning either.

SpaceX does use hydrazine-related components in Dragon and Crew Dragon, but they don't launch from Boca Chica (and rather small by mass) - AFAIK Starship is planned to be 100% methane-oxygen vehicle, justification for Mars flight.
What does "AEism" mean in this context?
Severance, extremely slow burning but turns into a great show.
Dude, the core tenet of this forum is making a good-faith [1] effort to really understand the fantastically complex issues at play here, and then to communicate about them honestly in a collaborative, rather than competitive, spirit.

You are not doing that.

Because people hate Musk (understandably so) and since, apparently, we can't hold nuanced opinions anymore, then they must also hate whatever the man has produced.

By the way, I absolutely despise the man and his antics, but I don't want to live in a world where SpaceX fails, just to spite him.
As were Ted Lasso, See, and Servant (all done now).
I love airships, but we really seem to be hitting peak something when billionaires can not just live in their floating city (124 meters long), forever.

I can’t wait for the jet packing up and down for parties and whatnot.

This seems like it’s out of Altered Carbon.
Yep, but then they go on to make the credulous woo-woo argument. None of us know what the actual results are here (since this is a conference talk, translated by a reporter), so I can only work with what they say.

In any well-done study with an effective treatment, you'd expect, a priori, that a reduction in intervention produces a reduction in effect. In other words, you don't benefit if you don't get the drug.
And psychics don't pretend to get into long-running feuds with each other, and pretend to settle those feuds with drop-kicks and suplexes, in front of mass audiences. (At least, not to my knowledge)

Did you think I thought, and was implying, that wrestlers and psychics provided the exact same services as each other?

Because I don't. You get that, right?
I think the issues are political. Musk hasnt done himself any favors, it seems every person has a very strong opinion of him and therefore spacex, Tesla, and X. I’m sure there’s lots of “whoopsies” going on in the agencies looking at the launch license where approvals, reviews, or even emails stay in the todo pile for weeks. One dedicated person could double the time spent at any stage in the process.
Interesting to hear this perspective, usually I just hear people fawning over TfL.

FWIW, TfL has been dealing with funding crises for years. I believe it is far less subsidised than public transit systems in other major cities. There was talk a while ago about TfL officially going into a state of "managed decline", where the priority would be attempting to mitigate the impact of funding shortfalls on service levels. Like, that was a phrase used publicly at the highest levels. I don't know if they ever technically activated that scenario but they have been on the brink financially at least since Covid.

As for the specific criticisms, I mostly use the tube which is probably the best of the TfL services. I am on the Northern line which is super frequent and reliable so I can't complain. The hub and spoke model does mean it's a pain getting from one non-central area to another non-central area. Buses are better for that but they do have issues with delays in my experience.

I moved here from a city with notoriously awful public transit so to me it's great, but I guess there are probably cities in continental Europe with far superior systems. Honestly though, it's 2023 and I still need to buy paper tickets for the Paris metro...
Ask HN: Do you use an external service for application configuration?
I'm interested in understanding how folks configure the systems they build and the reasoning behind those choices. I am mostly curious about those using online configuration services and APIs, as opposed to process-level configuration (env vars, command line arguments and files). But if you just use those instead, that is good to know too!

Some specifics that would be great to know about:

- What service do you use (something OSS, proprietary or home grown)?
- What makes it such a good fit for your use-case?
- Does it have any features to ensure your configuration is valid for your application?
- How do you understand what changed in your configuration during an incident?
- Does it favour consistency or availability?
- How do your applications access it? Does it support push, pull or both?
- Do you need specific permissions or peer-review to make changes to configuration?

The year of the Linux desktop could come not through the Linux desktop getting better but just by waiting for MS to get bad enough that it starts repelling people.

there was a time when most people couldn't write, and so you could have a well-paid job just if you're able to write. there was literally a job called a "scribe" where the only requirement was being able to write.

it just never stops. you learn some economically valuable skill, like writing, coding, and then some asshole teaches it to everyone and the skill becomes worthless.
This is definitely going to be a “markets in everything” link on Marginal Revolution
Refreshingly they did not talk about InternalFrameInternalFrameTitlePaneInternalFrameTitlePaneMaximizeButtonWindowNotFocusedState but tried to explain the reasons for separating code into objects and the difference between a class and an object. Could be useful for kids at a certain level.
I read the second example as: every set contains some elements that are totally unique to that set, and also some elements that are common to all of the sets, and nothing else. So I think it is a sunflower - any pairwise intersection just has the shared elements.

e.g 100 sets of integers, of size 3. Each set contains a unique number from 1-100, and every set also contains 1000 and 10000. Any pairwise intersection is {1000, 10000}.
"Their" is an important word here. Google's website nags you when you visit Google's website. Microsoft's browser nags you when you visit Google's website.
If I was Microsoft, I'd wanna know too. After all, it's a race for every single one of our data points, and then some.

Either way, you gotta admit it's ironically funny that Microsoft wants to keep/poach Chrome users into their own... wait for it... Chromium-based browser.
> The linux version of swift replicates a large number of native mac frameworks using whatever mix of C and C++ gets the job done.

Note that this is changing, on Darwin and Linux alike. Foundation.framework is transitioning from being a Swift interface over a C / Objective-C implementation to an Objective-C interface over a Swift implementation (https://github.com/apple/swift-foundation).

The language still has native C interop, and is gaining the same for C++, so it can delegate stuff like crypto to existing solutions like BoringSSL, but Swift-native solutions are becoming more common.
I always appreciated them for calling it Python 3000[1] at its inception to signal to users that it was going to be very different and take a long time to fully land.

It is a great example of how to do it, and I say that as somebody who used to write a lot of Perl 5 and kept wondering when Perl 6 was going to be available.

As an US corporation they would still need FCC and FAA licenses for all launches. In addtion, operating in a country that is not a US ally will significantly complicate compliance with export control and ITAR. The main relief from regulation would be that EPA regulations don't apply, and that hasn't been a major holdup:

> In the Written Re-Evaluation, the FAA concluded that the issuance of a vehicle operator license for Starship/Super Heavy operations conforms to the prior environmental documentation, that the data contained in the 2022 Programmatic Environmental Assessment remains substantially valid, that there are no significant environmental changes, and all pertinent conditions and requirements of the prior approval have been met or will be met in the current action. Therefore, the preparation of a supplemental or new environmental document is not necessary to support the Proposed Action.

The biggest issue with their last launch was that the flight termination system failed to destroy the rocket in a prompt manner and needs to be re-certified, regardless of where they launch from.
