Dependant on strikes (assuming at the money, assuming naked short) you would still profit if it stayed the same, or went up a little in price. Selling options is also being short volatility, so the 'bet' is that less will happen than is expected and, in the case of selling calls, with a preference for happenings to be downward.

A downward move could also see volatility go up significantly and increase the value of the options you are short, especially longer dated options.

It will have the same effect it always had if we proceed to do the same thing. i.e. fail to build more affordable housing.

How about this time we actually do it and stop blaming glue for not being a welding mold? Rent controls aren't supposed to be long term. Mamdami realizing that is already a good sign. So I'll see if he can get housing projects off the ground next.

> repeatable setups which you should be doing from the start

Yes, but not with

> TypeScript and CDK

Unless your business includes managing infrastructure with your product, for whatever reason (like you provision EC2 instances for your customers and that's all you do), there is no reason to shoot yourself in the foot with a fully fledged programming language for something that needs to be as stable as infrastructure. The saying is Infrastructure as Code, not with code. Even assuming you need to learn Terraform from scratch but already know Typescript, you would still save you time compared to learning CDK, figuring out what is possisble with it, and debugging issues down the line.

Jeff, it's very cool to hear from you as I have enjoyed your videos for some time. I would like to make one request though. Next time you do a project like "How I almost broke MrBeast's Ages 1-100 video" that involves setting up interactive electronics for an event, you should really call me. I managed interactive technology deployments for the automotive marketing industry for over a decade. It's a niche that has unique challenges which you fell face first into. I would be happy to help make things go much smoother should you ever do something similar. Proof: https://imgur.com/a/5z5JrwT I'm also on Reddit, same screen name if you want to dm me there.

Ok but the amount of education that is needed to join Jane St is certainly very large, but acquiring the language itself is probably a very tiny amount of that. That's exactly why I'm disagreeing: there is much more to know and to learn than the syntax and semantic of a programming language to do a good job, that's why when I consider hiring I'm not insisting too much about previous familiarity with a given language; that's the easy part.

You can't judge his behaviour without knowing his intent, and the culture of the late 80s and early internet.

Everyone hacked. When the internet was connected to Sydney University early 90s, all the students were grabbing Stanfords /etc/passwd files and peeking at the open X displays of people in Sweden. Etc. All for fun / curiosity.

You can be sure that even rtm's Dad did similar, perhaps confined to his lab / peers.

It's been a few years, but I remember jetbrains IDEs had these, though I'm not totally sure it was built-in rather than a plugin. Personally I find automated diagrams are not that useful. You generally need to have some understanding of what's happening to know what to hide and collapse to tame the spaghetti. So it needs someone in the know to be explanatory, and as a tool it requires a similar amount of fiddling to just drawing some boxes in slideware.

Yes but they are really less performant than claude code or codex. I really cried with the 20-25GB models ( 30b Qwen, Devstral etc). They really don't hold a candle, I didn't think the gap was this large or maybe Claude code and GPT performs much better than I imagined.

I second this. As a previous AI skeptic. VS Code with Agent Mode is amazing. Perfect amount of control over what the AI is doing. For me its been a game-changer. I would describe it as letting the AI do lots of the work and me being the guiding hand.

I will say, it is extremely important to have a good AGENTS.md file and other .md files that the agent can refer to when it needs to. Also having tests is more important than ever.

And when you notice common hiccups, document it in the AGENTS.md.

Slightly off topic, but I wonder if Quarto would work for you (https://quarto.org, disclaimer, I work for the company that maintains it). You write Markdown files with code blocks, and they're rendered into nice looking documents in a surprising range of possible form factors (see https://quarto.org/docs/gallery/).

You can also use .ipynb files as input instead of Markdown files and output to those same formats.

Traditionally, Quarto executes Python code at render time, but there's an extension called Quarto Live that lets you also incorporate Pyodide code blocks for the reader to use. https://r-wasm.github.io/quarto-live/ (I have not used Quarto Live before and have no idea what the limitations are.)

I didn’t agree with your first comment, but reading this one I think we actually have very similar opinions. I think your first comment sounded a bit too much like the libertarian nut jobs that comment on here all the time claiming drivers licenses are fascism.

There’s this quote I read recently: “When a political system collapses, the replacement is chosen from the choices available at the time ”.

I think it’s pretty clear to anyone with a brain that neoliberalism has failed the majority of people. Trump provided an alternative, and democrats ran on “nothing will fundamentally change”. The results are what we see today.

For an analogy: an Abelian group is a structure in which four axioms hold. A non-Abelian group is a structure in which three of these axioms hold, and the fourth does not. It is not a structure in which some random proper subset of axioms holds, because such a notion would be useless. While structures where specific subsets of axioms hold (non-Abelian groups, semigroups, monoids, etc.) are useful.

Yet as Mayfield's taskforce prepares to shepherd over 60 major employers through a three-year journey toward voluntary workplace health standards, a very different kind of Labour policy lurks in the wings. Chancellor Rachel Reeves plans to strip benefits from young people who refuse guaranteed work after 18 months of unemployment. The message is clear, if contradictory: we understand work is difficult for people with health conditions, but take a job or lose your support.

Not so much. The NY Metro Area has the highest GDP of any metro area in the US[0]. The San Francisco Bay Metro area ranks fourth, behind NYC, Los Angeles and Chicago.

But don't feel too bad about it. It could have happened to any Metro area.

Honestly though how many people reading this do you think have that setup vs. 85% of us being on a MBx?

> The Qwen3-Coder-480B-A35B model could also be run on a 4090 or 5090 by splitting the active 35B parameters across VRAM and RAM.

Reminds me of running Doom when I had to hack config.sys to forage 640KB of memory.

Less than 0.1% of the people reading this are doing that. Me, I gave $20 to some cloud service and I can do whatever the hell I want from this M1 MBA in a hotel room in Japan.

Hi HN, after reading through the comments sections on blog posts about RAG, I was finding a lot of differing views. Many people have had an entirely unique experience trying to implement a RAG system, due to the nature of their data, the scale and their goals. The underlying tech also changes so quickly that new methods show up every day, and old methods become outdated quickly.

I put together this blog post trying to capture some of the experiences we had building a RAG system at TrueState, and trying to put together a centralised, up-to-date review of the concepts.

If anyone has any feedback, suggestions, or wants to flame me for something I've gotten wrong, please let me know!

I have canceled my Claude Max subscription because Sonnet 4.5 is just too unreliable. For the rest of the month I'm using Opus 4.1 which is much better but seems to have much lower usage limits than before Sonnet 4.5 was released. When I hit 4.1 Opus limits I'm using Codex. I will probably go through with the Codex pro subscription.

Two wrongs don't make a right. Sure, the US decision was certainly ideologically motivated (which isn't to say right or wrong) and one could notice that, but that rabid reaction to an absolute nothing is ridiculous and the arguments presented are questionable in tone and intellectual integrity (e.g. calling your side "the world" to put weight behind your opinion).

Let's be honest, since Ars has been bought by Condé Nast, it has progressively become something between Reddit and Gawkers.

Lobbyists aren't the problem. They are doing what they are paid to do.

If you donate to a large charity, there is a good chance some of that $ goes to lobbying, as it should. (Presumably you want the issues goy care about to be fixed!)

If you work at a large company, 100% chance it lobbies, for good reason. Large employers lobby for better mass transit (because parking garages are expensive), more housing (because it is cheaper to lobby than pay employees more so they can afford $$$$ houses), or friendlier business laws (no one likes paying more taxes).

Lobbying is everything from "help us use orphans as a source of cheap protein!" To "keep the national parks funded".

Yes, location is becoming less important but there are differences in locally available talent and money. That’s the main reason incubators are forming in Europe too. If you are in the wrong place you will be starved for money and talent and others can outperform you. That what happened a lot, American companies outperformed European ones and when they needed to expand into Europe they could just buy the companies that are most similar in a few key markets here and expand from there. Being able to grow quickly enough to prevent that is sort of important if we want to own our tech giants.

I liked mine because my home/away schedule isn’t “routine”. It was much easier to have it known when we left the house and it would automatically turn down, and I could warm the place up when we were headed home which is great when it’s below freezing out.

Edit to mention that I was out of town one winter and my thermostat gave me an alert that my apartment had reached 40F! With my cats in there and a blizzard happening while I was four states away, I was able to ask a friend to walk over and check it out. Turns out my balcony doors had blown open during the storm, thankfully my cats wanted nothing to do with the snowy outside but I can’t imagine if they had been in that situation for the 3-4 days it would be before I got home.

It'll vary over time with the ambient temperature. When you set up a temperature control loop, you have a heater which creates a temperature gradient between it and the ambient temperature. This temperature gradient depends on the power that the heater is putting out, the thermal resistances of the box and any insulation around it. You then have a temperature sensor, which you will presumably put somewhere in the box, hopefully near the crystal, but it won't exactly be the crystal. Then, as the ambient temperature sensor varies, the power output of the heater will vary to try to keep the temperature that the sensor is seeing constant. But because that power also changes the thermal gradient, the thermal gradient in the system will also change, and so the temperature of the crystal is never completely insensitive to the ambient temperature, even if the temperature sensor reading doesn't change at all.

How big and/or meaningful this effect is depends on what the thermal resistances in the system are, and where the temperature sensor is relative to what you want to temperature control. Generally you want a very conductive box that's then insulated very well, since this means the temperature won't vary much across the box (all of the temperature gradient between the heater and ambient is 'taken up' by the insulation). But if you're talking sufficiently high precision this can be quite difficult to achieve.

Clinical trials are so expensive it only makes sense to run them if regulation mandates so. So without regulation you would never be able to tell snake oil from something that works. And then because making working drugs is more expensive than sticking a label on sugar balls they would get out-competed completely. Sadly, free market doesn't really work when the customer has no way to tell if a good is any good until it's too late.

Not sure why you were downvoted.. I think you are correct.

As evidenced by furious posters on r/cursor, who make every prompt to super-opus-thinking-max+++ and are astonished when they have blown their monthly request allowance in about a day.

If I need another pair of (artificial) eyes on a difficult debugging problem, I’ll occasionally use a premium model sparingly. For chore tasks or UI layout tweaks, I’ll use something more economical (like grok-4-fast or claude-4.5-haiku - not old models but much cheaper).

>How is it, that these well-established circles of the democrats, these well oiled machines, where in states like CA or NY (or most US cities) mayorships, senatorships, congressional seats, and governorships are basically handed out by the DNC, fail to win on those issues?

You should know this better than the US, but our "democrats" are center right for the rest of the world. The goal is to sound progressive but then act in neoliberal ways to appeal to donors, after the attention isn't on them. I call these "Establshment Democrats", more concerned with keeping the status quo and being a PR machine to the people than actually making policy that benefit the people.

That's why Mamdami can cut through by saying the things that Establshment Dems hated. And early on in his campaign when he gained momentum you can see the resistance against him by the Establishment, up to Cuomo decided to run independent after the primaries. I can't speak for the common person, but those actions speak a lot louder than any words Mamdami said.

There is a rift in the US Left, but I think it's one Estblashiment Dems had coming for a while now. If absolutely nothing else, the rampant destruction of the country by the Trump admin has absolutely activated people in ways not seen since 9/11. And when people are active, words aren't enough anymore. They want action, to not see military roaming their streets and kidnapping US citizens. They want to see actual ways to fix the economy as these trade wars sap at their wealth.

The collorary here is that the MAGA movement is also causing a rift in the US Right. There's definitely Esablishment Republicans that do not like this situation either. And there's the fact that all this is propped on one obsese, Dementia-ridden, 79 year old man. If/when he passes, there's going to be a huge power vacuum, and none of the headrunners are ready to fill that.

If anything, the split on the Right will be worse than the split of the Left, when it eventually happens. At least the Left is having new blood to try and push that rift from the bottom up compared to the house of cards that is Trump and everyone who tried bundling under him.

It can benefit from more complex algorithms, but I would stay away from "AI" as much as possible unless there is indeed need of it. You can analyse your data and make some dynamic thresholds, you can make some small ML models, even some tiny DL models, and I would try the options in this order. Some cases do need more complex techniques, but more often than not, you can solve most of your problems by preprocessing your data. I've seen too many solutions where a tiny algorithm could do exactly what a junior implemented using a giant model that takes forever to run.

Two questions:

(1) Are there any plans to make this compatible with the ducklake specification? Meaning: Instead of using Iceberg in the background, you would use ducklake with its SQL tables? My knowledge is very limited but to me, besides leveraging duckdb, another big point of ducklake is that it's using SQL for the catalog stuff instead of a confusing mixture of files, thereby offering a bunch of advantages like not having to care about number of snapshots and better concurrent writes.

(2) Might it be possible that pg_duckdb will achieve the same thing in some time or do things not work like that?

In the U.K. the far right are polling 30%. In a sane election system this wouldn’t deliver a landslide

In PR countries the populist right tends to be about 30% - France, Italy, or lower (29% Sweden, 15% Poland)

I don’t think it’s inevitable, but something has to change. Europe can’t take a billion extra immigrants from climate migration, even if they integrated.

Wealth disparity is ballooning, with fewer people owning more and more, and that’s likely to snowball in the next 20 years as the wealthiest keep accumulating and power shifts more to weary and away from work.

Could it be any other way? Are there people that understand how money works and won't apply it for their own case?!

We each do our best for us and our own - it's natural. Capitalism is ensuring the society advances and benefits disproportionally more.

Take Bezos for example: his wealth is about 255B but the company he founded has a market cap of 2.67 trillion - that 2.41T difference is wealth created for other people. Not to talk about the products and services improving the society and our lives every day...

> 2. What's easy to underestimate for _developers_ is that your self hosted setup is most likely harder to get third party support for. If you run software on AWS, you can hire someone familiar with AWS and as long as you're not doing anything too weird, they'll figure it out and modify it in no time.

If you're at an early/smaller stage you're not doing anything too fancy either way. Even self hosted, it will probably be easy enough to understand that you're just deploying a rails instance for example.

It only becomes trickier if you're handling a ton of traffic or apply a ton of optimizations and end up already in a state where a team of sysadmin should be needed while you're doing it alone and ad-hoc. IMHO the important part would be to properly realize when things will get complicated and move on to a proper org or stack before you're stuck.

To be clear Trump is also about keeping status quo. He is just much more blatantly corrupted so he will sell to highest bidder instead of honoring past allies/deals.

These limits of power were always Obamas excuse when he was supposed to push for something inconvinient. That was the narrative to not try too hard. When you start to look at what hes done… the small things, the mundane and the stuff he had clearly power over. It's not good. Biden was very different in that aspect.

I took care of IT for a startup hedge fund once. I was the quant's right-hand man, data engineer, visualization dashboard guy, everything. The quant needed to run a monolithic C++ program daily to chew through stock data and we decided a dual-Xeon server with 512 GB RAM would be great. OVH MG-512, for those curious.

Quant happy, boss happy, all good. Then the boss goes for lunch with someone and comes back slightly disturbed. We were not buzzword compliant. Apparently the other guy made him feel that he was using outdated tech by not being on AWS, using auto-scaling etc;

Here I am, from a background where my first language was 8086 assembly, and compactness was important to me. I remember thinking, "This whole thing could run on a powerful calculator, except for the RAM requirement".

It was a good lesson for me. Most CTOs know this bias and have unnecessarily huge and wasteful budgets but make sure they keep the business heads happy in the comfort that the firm is buzzword compliant. Efficiency and compactness are a marketing liability for IT heads!
