Um, please do not suggest people ask that.

If you are having to ask an LLM how to do it, I strongly suggest NOT starting with shorting.

Ask about Put options, which is what Burry is doing here — not even Burry is shorting for this situation.

I'm no expert trader, but the potential losses for shorting are unlimited. You borrow X shares of a stock, and will have to repay your loan in that stock, whatever it costs. If the trade goes against you, you will get a margin call and will need to (re-)fill your account with whatever funds are necessary to pay that amount, or all your other holdings and that position will get sold automatically at whatever that loss amount is. Situations called a "Short Squeeze" arise not infrequently, and even though they are temporary, they can cause a stock price to skyrocket, specifically because so many people are shorting it, and everyone needs to buy to fill their short positions & margin calls. The fact that the price soon falls again helps you not one bit. Plus, the maximum profit is limited to the value of the short. E.g., you short the stock at $100/share, if the company goes bankrupt, you can repay the shares for $zero, making $100/share; but you could lose $1000/share if it goes up 10x.

In contrast, purchasing Put options, the right to sell the stock at a certain price, limits your loss to the cost of the Put options — if your idea turns out to be no good, it just fails and expires worthless.

Here's some MUCH better information:

> This is specious reasoning, as "optimized" implementations typically resort to performance hacks that make code completely unreadable.

That really depends on context, and you're generalizing based on assumptions that don't hold true:

Replacing bloated ORM code with hand-written SQL can be significantly more readable if it boils down to a simple query that returns rows that neatly map to objects. It could also boil down to a very complicated, hard to follow query that requires gymnastics to populate an object graph.

The same can be said for optimizing CPU usage. It might be a case of removing unneeded complexity, or it could be a case of microoptimizations that require unrolling loops and copy & paste code.

---

I should point out that I've lived the ORM issue: I removed an ORM from a product and it became industry-leading for performance, and the code was so clean that newcomers would compliment me on how easy it was to understand data access. In contrast, the current product that I work on is a clear example of when an ORM is justified.

I've also lived the CPU usage issue: I had to refactor code that was putting numeric timestamps into strings, and then had complicated code that would parse the strings to perform math on the timestamps. The refactor involved replacing the strings with a defined type. Not only was it faster, the code was easier to follow because the timestamps were well encapsulated.

Well, dealing with large analytics queries will always perform better with larger amounts of memory... :D You can perhaps tune things to perform based on the amount of system memory (IME 80% is what DuckDB targets if not otherwise configured). Your proposed system does sounds like it introduces quite a bit of complexity that would be better served just by using hosts with more memory.

As far as Iceberg is concerned, DuckDB has its own implementation, but we do not use that; pg_lake has its own iceberg implementation. The partitioning is "hidden" because it is separated out from the schema definition itself and can be changed gradually without the query engine needing to care about the details of how things are partitioning at read time. (For writes, we respect the latest partitioning spec and always write according to that.)

Just go pull up his bibliography. Chord, the Click Modular Router (super big deal to me), RON (also a big deal to me), Vivaldi (which made its way into the Hashi products). He had a hand in a lot of stuff. His pre-CSAIL work was very much like that of the LBL Network Research Group (that's Van Jacobsen, Vern Paxson, Steve McCanne) --- he's in that league.

It's a good option for primary care. It's also a form of insurance, since the reason why it's low is that enough people will subscribe but not use it, just like the gym :)

The issue is that primary care is not generally expensive, and also not generally needed if you're healthy. I've gone to a PCP less than half-dozen times in my 56 years. So the $100/mo is a waste in my case -- I save much more by just paying out of pocket if every I need to go.

But medical expenses for unexpected conditions -- surgeries, specialized tests, visits with specialized doctors, non-routine medications -- those are all what cost a lot. And that's not covered by $100/month.

So DPC is a nice idea, but it doesn't really replace health insurance -- I look at it more as an "extra" for regular health monitoring and preventative care, which is important in itself (and in most cases worth the $100/month).

An interesting side effect of the US testing and association with Marshall Islands is that they were offered entry in the compact of free association, allowing Marshalese citizens mostly free travel and work rights to come to the USA and work and reside without a visa. Which offers . And vice versa, US citizen can live and work indefinitely in Majuro without visa.

About as many Marshallese live in USA as on the islands.

> won’t be commensurate with the risk he took on

Former options market maker here. We have insufficient data to conclude that.

I also happen to have experience unwinding correlation books after their originators shat the bed. Predicting a crisis is hard. Predicting correlations in a crisis for esoteric assets is almost impossible.

Burry wanted to bet on specific overvalued stocks. Not a general market crash. For that, puts are probably the best tool if the expectation is a sharp correction followed by, in all likelihood, a Trump put.

I agree with this. I have no problem with a technical discussion comparing the features and discussing Jupyter’s shortcomings. But the Jupyter job postings and contribution graph screenshots felt both ill-spirited and not particularly relevant.

There was interesting stuff here: the human readable format, auto publication. But the tone and framing bashing a reliable open source project really turned me off.
Show HN: Batch Claude Code tool calls into one using chat history to save tokens
by buremba | 2025-11-04 18:37:52+00:00
Hey HN! I usually create helper scripts for Claude to reuse and organize the file structure, allowing me to run multiple agents on the same codebase. I had around 150 conversations for a project, so I wanted to see if I could automate the process of analyzing my conversation history to see if I could build something valuable from it.

Apparently, conversation history is gold for spotting repetitive tool calls. I deleted a helper script that I had recently created from the repository and the conversation history, and Claude suggested that I make them when I ask it to suggest helper scripts.

I had to perform data cleaning & enrichment on the conversation history to make it worthwhile for CC, so I've turned it into an open-source plugin anybody can use. It's handy for both repetitive workflows and coding use-cases.

The script adds a `/agent-trace-ops:plan` slash command, and all data is processed locally via your Claude Code. Let me know if it's useful!

You can take your analogy further. The buffet noticed you pausing on unhealthy food, and begins replacing all the healthy options with unhealthy options. People shame your criticisms and note you could easily put blinders on and intentionally look longer at healthy options anytime you accidentally glance at an unhealthy one. the alternative would be an absolute repression of free speech after all.

I would like to use my phone like the general computer it is. I should be able to install whatever browser I want and whatever app I want. I should be able to purchase digital products without a monopolistic tax to Apple. I should be able to not have a broke experience when I use iCloud or iTunes on windows.

This tutorial explores how AI models can solve complex, multi-step queries by composing and decomposing function calls - similar to how we break down problems ourselves.

The approach demonstrates how an AI can: - Decompose a complex task into subtasks - Execute each part through separate function calls - Compose results into a final, structured answer

The article connects this to fixed point theory from mathematics, showing how iterative refinement converges to a stable "consensus" result. Includes practical code examples using OpenAI's API.

I make no such case, you’re right. All laws are backed up by state violence. But that doesn’t mean you can call every law “violent”, or random government actions “terrorism”.

It’s like calling a father who tells his kid to help with the dishes “violent” because waay down the line in the most pathological broken situation imaginable the authority a parent wields over their child is backed up by violence and the ability to withhold basic necessities. It’s ridiculous, he didn’t beat his kid up, he said “come help do the dishes”.

You’re doing that, but with the state. It removes all nuance. Don’t do that, it hurts your argument.

I mean seriously your point boils down to “Chat Control is a law, and laws are backed by violence, and therefore it’s terrorism”. That means “don’t park on the sidewalk” is also terrorism! Why am I even arguing this? Gaah I so hope you’re just trolling me.

It's close to sharepoint and sharepoint takes around 15MB to download.

If you want to run something like sharepoint suite locally, this is the best option. Question is - do you want/need to run sharepoint locally?

I hate javascript and I have it off by default. With that being said, this is a huge app with tons of options. Other apps without compression are just as bad

Draw io - 25MB

Outlook - 30MB

Gmail - 30MB

The difference is, this is oss, anyone can contribute and fix it

To expand on the original reply to you - shorting companies, or engaging in almost any stock-based activity beyond “buy and hold,” typically entails much, much higher risk than just buying and selling stock. The most you can lose when buying a share is the purchase price, and that’s fairly unlikely, but when you start getting into even options/etc, you’re magnifying your risk - small swings in the market can lead to large and disproportionate losses, and when you get into shorting in particular you can lose far more than your initial investment. This is why you’re getting the reaction you’re getting - because the thing you’re asking about is sufficiently risky that if you're asking on Hacker News (and not, say, asking a professional), you don’t understand the risk profile well enough to do it “safely.”

That, and because snarky answers get more imaginary internet points than helpful ones.

Will it be another "correction" where it pulls back ~10% before going up another 15%?

The powers that be have too much invested in the market continuing to move up, you are basically betting that Trump, a bunch of billionaires and the FED are going to let the market crash to curb inflation and income inequality. That feels like a bad bet to me.

Because it's not linear but there's still an equation. It's not arbitrary. Meaning, 1 day of work is obviously less productive than 4. But 4 might not be less productive than 5.

It's also not about half-assing. If you work someone 80 hours a week, and they work as hard as they possibly can, they will still likely be less productive than if they just worked 40 hours. Because they start making mistakes, which they then have to fix, and make more mistakes while they fix those mistakes...

After a certain point, your productivity might be negative. Meaning, no employee at all might be more productive than an employee working 100 hours a week.

The problem (if you want to call it that) with following a person on sites like Bluesky or X is that people aren't machines and won't stay "on topic" regarding the reason you followed them in the first place. You might follow them for software dev, biking, birding, or whatever, but one day they could suddenly start ranting about their own political opinions or crazy beliefs.

IMO, Reddit/HN-esque sites are better for following topics, and Bluesky/X/Mastodon are better for following people. Maybe hashtags are a good middleground but I don't have enough experience using those sites to say.

(Disclaimer: I don't use any social media except for HN.)

By "least productive 20%" I also meant the time during the week when your oomph is gone. IIRC most experiments on shortened workweeks show that motivation and productivity in general go up because workers are less stressed, better rested, happier, etc., and output does not take a big hit.

Of course it might be just an observation effect, but I think that is normally controlled for.

In my office :) Southern Europe if that's the question, and I work for myself, contractor/freelancer jumping between existing relationships and kickstarting new startups trying to find product-market fit.

Never visited the US, never had any plans to visit the US and don't have any relationships with anyone/anything from the West coast in the US, FWIW.

I'm here because HN is filled with interesting people from all over the world, even encountered a childhood (programming) hero once or twice and managed to get questions answered. The wide range of people is why I keep coming back after almost two decades of being here.

I mostly use https://news.ycombinator.com/active as a "frontpage", it's sorted by most active discussions rather than "trending upvotes", as I'm mainly here to read and write comments, rather than finding new articles. I think using any of the other "lists" as a frontpage might give you a different impression, because I certainly feel like HN is more "Pro BigTech" than any other websites, if anything I'd probably say the opposite, but probably the truth sits somewhere along the middle.

> You didn't really answer my question, you just assured me that your opinion is right.

Its not an opinion; whether we have a method of resolution is a verifiable question of fact, and the answer is yes, we do.

Juries make decisions where the key evidence is conflicting testimony of two witnesses all the time, where the other evidence, if any, isn't directly on the primary question but the reliability of the witnesses.

Usually, this will resolve against the accuser where the US criminal standard of proof (beyond a reasonable doubt) applies, and have more mixed results where lower standards, like the preponderance of the evidence or clear and convincing evidence standards used for various purposes (e.g., usual judgements and permanent restraining orders, respectively) in the US civil justice system, apply.

Whether this resolution mechanism has satisfactory results is, of course, a subjective question.
by constantius | 2025-11-04 18:42:09+00:00
I think people disagree with you because you take the position that, because the worst that could happen (I'm assuming nuclear war or something else "unrecoverable"?), those people are not that bad. This is a bad faith argument, because the lower end of your badness scale is pretty much unrealistic. What has been unrecoverable in human history up to now? Does that mean that no person/ideology has been "terribly terrible"?

Your debating style in your thread is also very patronising, which doesn't help.

If you fail to see the perspective of all those killed, or of the whole of the Middle East region, but only choose to see it from the point of view of the US or humanity as a species, then of course you're right.

I'm not involved in any capacity with the development or use of Jupyter—I think ipynb is fundamentally flawed at a deep level, starting with its (I)Python roots—but this company's framing of their product as "the successor to Jupyter notebook" comes across as passive aggressive at best and misleading at worst. What is their relationship to Jupyter besides building a Jupyter alternative?

>and if you are shooting still (and not video) there's really no good reason to ever delete an image off an SD card

There are tons of good reasons.

When downloading images off the card, software has to read all the files on it - which can take a very long time if the card is full of photos you've already processed in a previous session.

Then there's that you shouldn't be keeping most of the shots you take. Unless you're a still life artiste, most people (including professionals) take multiple pictures to account for blinking, moving objects, slightly different angles, etc. You should keep the best shots and delete the rest - storage is cheap but having to go back through all the garbage to find the good shots in the future is pointless.

Modern cameras have large sensors that produce large files. It's wasteful to keep buying more and more SSD cards. Just build a NAS or pay for cloud storage.

How do you know they work? We haven't tested one in 33 years. Are you still confident after 50 years? 75 years? We all see the problems with aging physical infrastructure - bridges collapsing, dams failing. If you are relying on nuclear weapons as the primary deterrent to stop major wars, they need to work, and people need to know and believe they work. The cost is negligible.

> high IVs. You’re paying for that.

Glad to see someone say it. A lot of people have a hypothesis about the market, but fail to do the follow through to see if the market has already priced that in. The real aim should be to see when your model (mental or mathematical) prices things differently than the market.

In this case, it's actually quite reasonable to believe that the market has over priced the risk no matter how "sure" anyone is that these companies are over valued. It's entirely reasonable to pay for an option that you think reflects an unlikely scenario, but you also believe is mispriced notably by the market.

I wrote both "Game Programming Patterns" and "Crafting Interpreters" largely in chunks around half an hour between work, parenting, and other life duties. Likewise lots and lots of hobby programming projects.

Context switching is a skill that gets easier the more you practice it, just like any other. There are techniques like leaving good notes to yourself to pick back up where you left off more easily, but a lot of it just mental training. You sort of learn to hold some of the context in your head all the time but keep it idle when you aren't using it.

When I'm hacking on a hobby programming project, I can often fix a bug or tweak a small feature in fifteen minutes, make a commit, and get a little serotonin hit, all while I'm waiting for the wife and kids to get ready to leave the house.

It doesn't always work for all kinds of tasks. Sometimes for more challenging stuff I really do need a larger chunk of time to load it all in my head. But you'd be surprised how easy it is to eat an elephant one tiny bite at a time if you really try.
