Thanks! To answer your questions:

*Backends:* Currently supports Qdrant, pgvector, Weaviate, Chroma, and Pinecone. Adding more is straightforward since it's just implementing a Store interface.
Let me know if I missed some good backend!

*Relevance scoring:* No LLM-as-judge — that's intentional. RagTune focuses on retrieval-layer metrics only:

- Vector similarity scores (what the DB returns)
- Recall@K, MRR against your golden set
- Score distribution diagnostics

The philosophy is: debug retrieval separately from generation. If your retrieval is broken, no amount of prompt engineering will fix it.

For chunk size/overlap optimization — exactly the use case! `ragtune compare --chunk-sizes 256,512,1024` lets you see the impact directly.

Happy to hear feedback if you try it!

Apologies, brain glitch: it's half, not third. Also, I'm talking about the effective tax rate, not the marginal tax rate. Here are the numbers:

Median salary of a full time employee in the UK in 2023 (to match the German source): £34,963 [1]

Take home on that salary (after income tax and NI): £28,692 [2]

Effective tax rate on a median salary in the UK: ~18%

Median salary of a full time employee in Germany: €4,479 pm [3] or €53,748 per year

Take home: €34,281 [4]

Effective tax rate on a median salary in Germany: ~36%

Tax _rates_ are not that different, but the previous British governments really ramped up the tax-free allowance, which significantly reduces the effective tax rate.

> The 4080 is a 4090 die with some SMs disabled.

The desktop 4090 uses the AD102 die, the laptop 4090 and desktop 4080 use the AD103 die, and the laptop 4080 uses the AD104 die. I'm not at all denying that binning is a thing, but you and other commenters are exaggerating the extent of it and underestimating how many separate dies are designed to span a wide product line like GPUs or Apple's computers/tablets/phones.

We had nationwide riots for months back in 2020 over a police officer murdering a suspect, and that resulted in approximately zero actual political change. During the recent shutdown over the budget, we had one of the largest protests in the country’s history and massive shifts towards the opposition in elections followed by them immediately folding in exchange for essentially nothing.

The political class is very well insulated from the popular will in this country, and I fear we may be nearing the boiling point.

I was never religious - my mom made an effort to bring me and my siblings to church every Sunday so that at the very least we wouldn't stand out in this deeply conservative environment.

My decisive moment was pretty silly in hindsight, but I stopped going to church after that. I was ten and me and my friend spent the better part of an afternoon after school collecting buckeyes (aka conkers, horse chestnuts). We were headed home with our spoils but when we were passing a church, my friend recalled that there was some kind of holiday that day and he had to attend mass. He gave me everything he had collected and joined the crowd standing there in the cold.

> When a bully is threatening you, the very worst thing you can do is to give in to the bully

Agreed in principle, but in this case there are two bullies to worry about which changes that equation.

You can choose to align with the bigger tougher bully who is periodically reasonable, has a lot of shared values, and generally has been historically friendly to you. They only occasionally get grumpy and have to be placated. This alignment has, can, and will protect against the other bully.

Or…you can chose to not align with them because they went and got grumpy again and the consequence of that is they will just ignore you when the other bully comes calling to kick your ass.

Factor in that you can’t align with the other bully at all because they have never ever been friendly or reasonable to you. They also don’t have hardly any shared values. They cant protect you from the other bigger tougher bully anyway. So its a moot point.

At the end of the day you are faced with a sort of global political version of Pascal’s Wager.

Hey HN,

I built RideCave, a free browser-based virtual cycling app focused on track cycling.

It runs entirely in the browser, connects directly to smart trainers, and has no install or subscription.

Try it here: https://ridecave.com

It includes 100+ free structured workouts, a buncha mini-challenges, and 18 real-world inspired velodromes you can ride or race on using your own trainer.

What makes it different:
• Real physics - "Newtonian simulation" running hundreds of times per second. Banking angles, air resistance, rolling resistance, inertia, rider weight, and power are all modeled. Physics runs fully client-side and deterministically. Milisecond accuracy.
• Energy (kWh) tracking - In addition to watts and TSS, RideCave tracks cumulative energy output in kilowatt-hours, with real-world equivalents (for example how many times you could charge a phone).
• Browser-native -Uses the Web Bluetooth API to connect directly to FTMS trainers like Wahoo KICKR, Tacx, and Saris. Works in Chrome and Edge on desktop. No plugins or installs.
• Privacy-first - people can ride as guests and data stays in browser.
• Track and more - Part mission to bring track racing, workouts, and fun to virtual world with formats like flying 200m sprints, pursuit-style intervals, elimination races, plus short mini challenges.

Tech stack: React 19, Vite, Three.js, Web Bluetooth API, Supabase for optional sync.

I’m a cyclist who got tired of paying $20/month for Zwift when I mostly just wanted structured track workouts. Built this for myself and figured I’d share it. May create a paid tier at some point but that's not why I'm building it now.

Would love feedback, especially on overall UX, product direction, and experience. What would make you use something like this over existing options?

They're talking about our nascent circular economy.

Recycling now recovers >95% of raw minerals (and will continue to improve).

The learning curves for battery and solar tech will more than make up the for the shortfall.

Meaning at some point in the near future (2050 IIRC), humanity will have mined all the lithium it'll ever need.

Also, in the same time frame, it'll be economical to mine our garbage dumps. Further reducing the need to extract raw materials.

There's context. Hank Green talked about it in https://www.youtube.com/watch?v=9zi0ogvPfCA, but in short, paraphrasing, and adding my own thoughts:

Jimmy Wales has been poked at with the question of whether he should call himself a founder or specifically co-founder for a long time, by right-wingers who think Wikipedia is too woke, and want to irritate and discredit him as much as possible, and instead raise up his co-founder Larry Sanger. Sanger has right-wing views and a habit of accusing any article as biased that doesn't praise Trump and fundamentalist Christian values, and takes these as proof that Wikipedia has a left lean.

The interview Wales walked out of was for his book tour. I imagine it's the umpteenth interview that week with the same question asked for the same transparently bad-faith reasons, trying to bend the interview away from his book and into right-wing conspiracy theory land.

> Democrats should blame MAGA and Trump more. No amount of rational policy messaging will help against MAGA and Trump when you let them set the framing. All of this is caused by MAGA and Trump. Not by democrats. By republicans and especially conservatives.

Sorry, they've done that so much that people have become deaf to it.

> It is ridiculous abuser logic to blame your immoral choices on opposition for not opposing you better. Right wing people, including farm people, should have own moral agency. They are not toddlers and yes they should be blamed.

Thinking like yours is a big reason the Democrats lose. "Me, change to become more effective? Of course not! Here's some moralistic gesticulating to justify myself."

You basically want to lean all in on negative campaigning. But bashing the other side doesn't cause people to support you. However, it's a really seductive option when you're unpopular and refuse to change. It's not a strategy, it's a cope.

> Oh please. Yes we would, in fact we would be in the bigger mess. We would had two fascist parties instead of one.

You don't know what the hell you're talking about. Despite your intentions, you're probably helping MAGA more than you hurt it.

I remember looking at python profiling tools a couple years ago and being pretty disappointed. Most added a huge amount of runtime noise, the lowest being something like +50% runtime, which to me is completely unacceptable. The profiler I wrote and use every day for a side project adds well less than 1% runtime overhead.

I wonder what the overhead of sys.monitoring is. It is possible to instrument functions like this without using that API.. you can just walk the AST at startup and do it yourself. Would be interesting to see a very minimal instrumenting profiler that did that and compare the two.

I also love the 'targeted'/instrumenting profiling API. I think sampling profilers are good at scratching the surface, but quickly run out of useful information when getting down to the goods. Happy to see people doing instrumenting profilers.

Thanks for sharing :)

Are any of those things threatened and need defending?

Assuming OP isn’t an illegal alien or attempting to impede federal law enforcement, they’re fine.

Assuming his job isn’t reliant on employing or generating revenue from illegal aliens, also fine.

Way of life: America had immigration laws since 1875 - his great great grandparents probably lived under more onerous immigration regulation (Chinese Exclusion Act, etc) than modern Americans and immigrants live with. Also fine.

For what it's worth, I have lived in, and currently spend a lot of time in, both places. You're both very obviously wrong.

There is a serious problem in the US. There is also a serious (though different) problem in the UK. The problem in the US is the chilling effect of the vindictiveness and lawlessness of the current regime. I will not elaborate on this because it's too complicated to communicate effectively in a forum post.

The problem in the UK is a set of vaguely and arbitrarily specified-and-enforced laws that enable the criminalization of 'grossly offensive" speech. There is no statutory definition of what constitutes a 'grossly offensive' communication -- all enforcement is arbitrary and thus can be abused. Whether is it actually abused in any widespread fashion is irrelevant.

- Communications Act 2003 (Section 127): Makes it an offense to send messages via public electronic networks (internet, phone, social media) that are "grossly offensive," indecent, obscene, or menacing, or to cause annoyance/anxiety.

- Malicious Communications Act 1988 (Section 1): Applies to sending letters or electronic communications with the purpose of causing distress or anxiety, containing indecent or grossly offensive content.

Hah, funny you bring up the name of a neighbor :)

I'm not sure that's even in the same class of issues as what's happening in the US and frankly, a bit surprising to hear. Have you seen/been with ultras in the Nordics? Even been to derbies played in Copa Libertadores? Both of those I'd immediately rank as way more violent than what we see here in Spain.

Opposite experience here. My aging mom had been on Windows XP for years and years, and then someone gave her a cast-off laptop running Windows 10.

That was such a culture shock. Endless pop-ups to do this and subscribe to that and so on. And it has gotten worse since then of course.

Instead I set her up on a nice mature Linux desktop - Mate - and that was fine. Chrome, Thunderbird and not much else. And solid reliable and nobody reaching in from the cloud with the latest attempts to monetize something or push AI onto you or whatever. You turn on (unsuspend) the computer and it's the same computer it was yesterday, working just the same.

You go ahead an tell users that.

Tailwind docs are also the source of, duh, docs. People browse them way less and as a result Tailwind gets way less funding.

The problem is that Wikipedia should be set for life at this point, and they insist on rejecting that notion. There may be a future in which Wikipedia closes, and if that comes to pass it will due to wanton disregard for people's goodwill.

I want an improvement upon "Encyclopedia Brittanica". If we have to have governments around the world fund a nonprofit educational equivalent of that, then I'm all for it but we can't keep depending upon a least-common denominator "central public knowledge repository" that's an improperly-managed, easily-manipulated, often incomplete and inaccurate mobacracy fed by largely unknown randos, enough of whom aren't doing so for honest purposes and too many are foolish/crazy/unreliable enough to curate and preserve worthwhile information consistently.
by alpine_accentor | 2026-01-15 17:15:54+00:00
It makes perfect sense to concentrate law enforcement in a state that is in defiance. Even if the absolute numbers are low, the state cannot back down from enforcing the law because some people are resisting. Otherwise you invite anyone to disregard any law they don’t like. The state won’t allow this and the only way to overcome this is either to change the law or toss out the government, and only one options is realistic. And btw I am against deportations of people who have committed no felonies unrelated to immigration.

The Wikipedia "reliability" list shows wild, almost laughable biases.

https://en.wikipedia.org/wiki/Wikipedia:Reliable_sources/Per...

Surely people don't think sources such as Mother Jones are more 'reliable' than The New York Post, Fox News, or The Heritage Foundation? Not a coincidence there.

Having such obvious biases does nothing but damage the Wikipedia brand, and at this point has me anticipating Ai replacements.
by chairhairair | 2026-01-15 17:17:05+00:00
The point is not that Wikipedia is completely unbiased. That's an obvious impossibility - for any encyclopedia.

The point is that accusations of "noticeable bias on any topic that has political implications" is the kind of accusation made by someone simply trying to sow distrust in information, writ large. It's increasingly common.

Being asked for an example or two isn't weird.

Was wondering the same. "Do one thing and do it well" philosophy...

If I want to run remote commands, I know how to do that already (namely, as you've shown), why learn to use a new tool for it? It's like these options to tar for compression: if I want to have a gzipped tar I'll run the tar c /sdcard output through |gzip thank you very much! (and drop in zstd instead)

> How many ppls can they deploy in the long term?

How many "ppls" did Afghanistan deploy, long-term, against TWO different superpowers, with only discreet, behind-the-scenes support from other nations?

Invasion and control of another country that has more than paleolithic technology is pretty damned hard. Harder than anyone who attempst it ever guesses. ("They will welcome us as liberators!" - the stupidest thing ever said by a pre-Trump POTUS.)

It's even harder if a majority of the invading population hates the idea, and a significant part of the military doubt the constitutionality of their orders.

Oh, and two nuclear powers would be openly defending Greenland.

It would be cheaper and more popular to pile $9B in bills on the National Mall and set them ablaze.

I was unemployed for six months in 2023. Some of that duration was self-induced. My wife did not want to relocate across the country and I did not want to go back to being a junior web developer, or senior positions that sounded very junior, as I have 20 years experience. Fortunately, I landed two opportunities unrelated to writing JavaScript at once and I took the lower paying one because it was fully remote.

Here is a list of things not to do:

* Don't waste time using employer online career portals. These only continue to exist to satisfy EEO legal requirements. Most employers don't respond to these.

* Don't pad your resume. Make every line of your resume count as if it were being read by a human. With AI tools now filtering resumes they are getting better at bullshit detection.

Things to do:

* Upload your resume to places like Indeed, Zip Recruiter, Dice.

* Be very specific on your resume. Yes, you should state something about your tech stack in the fewest possible words, but anything related to competences should be expressed in quantifiable terms only. For example you saved the company billions of dollars, or shipped 200 features to production, or reduced execution speed by 50%

* Be clear about your experience and what you are looking for.

* Have external credentials like PMP, CISSP, security clearance, and more. These open doors for you that you currently don't realize are closed to you and likely pay more.

Hey, thanks for taking a look!

> I'm struggling to figure out what you're good at

Can it not be all of them? :p

That's one of my big challenges with resumes. People assume I can only be good at one thing and/or assume that I'm lying about my work experience.

I can get _really good_ references from all of my previous employers (because I am legitimately good at everything on my resume), but I never seem to get to that point.

Historically, if I get a technical interview, I get the job every time. The challenge is getting the technical interview.

Because I was not a Communist

Then they came for the Socialists

Because I was not a Socialist

Then they came for the trade unionists
And I did not speak out
Because I was not a trade unionist

Then they came for the Jews
And I did not speak out
Because I was not a Jew

Then they came for me
And there was no one left
To speak out for me

That’s not an answer. Please explain why it’s a bad thing that Palantir had produced an application that shows ICE agents the probable addresses of people they’re supposed to deport along with information about them.

If the answer is “I don’t believe in immigration law and the government should not enforce it regardless of what people vote for”, that’s a completely acceptable answer.

I feel like if RPI doubled down heavily into education, they would be in a much better spot. They really could never win on price in the long run. But having a bit of K-12 and university budgets going to RPIs every year, especially during the "teach the kids programming" era, would I think make them a much healthier business.

Chromebooks did what RPI should have done.

I think it's something different than "Americans are passive" - rather, many of them/us perceive the context of what you're seeing very differently. I can share some of this perspective though I don't insist it's the only way to feel.

1. Americans on the ground are clearly feeling the effects of illegal immigration. As an example: a an African American janitor in our kids' school voted republican in 2024 for the first time in his life, because the park in his Brooklyn neighborhood has become a shanty town and he can't work out there. In that election we've seen nearly every demographic move more republican than before, and I think this is the key issue for them.

2. In that context, when ICE does something, even when we don't like it, people can understand it in the context of a larger problem they/we want solved. When you perceive "passivity" - it's because you come in from a perspective of not wanting the underlying problem solved which is fine, but it's different for people who like "what" is happening even if not "how" it's happening.

3. There are plenty of people protesting and violently rioting if that's what they feel like.

The deeper you get the lonlier you get.

And that can happen even when you are among 1000s of people, not just alone , if you are among people thinking of something else, staring into the void or that you can't connect etc. you are a deep person.

Deep person + deep thinker is the worse. Also people aren't doing them any favor by singing the praise of being a deep person and a deep thinker.

It also has to do with abundance of everything and being not in need of cooperating 24/7/365 to avoid starving ....some people slip into deep thinking and deep emotional introspection...yeah fuck that
