I think it's possible to housing to be affordable and for it to behave more similarly to to something like gold than something like a bond or stock. That said, it's quite tricky because of property taxes - if they applied to gold imagine what it would do to gold bugs. Fortunately, real estate can be rented, which isn't really a thing for gold.

But to complete the analogy, it seems like the goal should be for residential values in terms of build price per some typical target like ~1500sqft/3br (regardless of form) to remain relatively constant adjusted for inflation and relative to % of median wage while allowing land value to adjust density to match. This allows people to gain from selling to convert from low density to high density, but keeps affordability relatively constant. This likely means that some kind of alteration in tax or sale regime to promote transition to higher density and not just transition to higher value should be present in the market. (IE in places where 1acre is going for ~$1million, it should make more sense for someone to buy and convert to multiple units than for someone to just buy.) This would lead to expensive areas starting to convert to higher density leaving lower value areas to the main option for single family inflows. (Of course this will have loopholes - obviously it incentivizes the "rich enclaves using a COOP" type of model if the tax pressure were assessed at sale - so it need to be thought through more clearly.)

Edit: That said, I do think there's something to your organism analogy. For example, all of what I wrote above given, it explains why it'll still be impossible to find a good plumber and that does interact with the price of building.

From what I've seen so far, one company does something and the others do the same to not get left behind.

Company A hires like crazy due to Covid, then everyone else does the same because they must be on to something!

I agree, I don't know why they expected covid conditions to be the new normal.

I think the only company who didn't get on the crazy hiring bandwagon was Apple.

> heckling people about the term used to describe the people is not going to move the needle on that issue

I disagree with this; this is the primary means by which dehumanization occurs. I like to think of "police officer" as the perfect dehumanizing term because it showcases that dehumanization is not always negative. Some people will hear the term and automatically think good things and some will automatically think bad things. Few will think about a person they don't know, complete with vices and virtues they may or may not agree with. The point is that dehumanization makes you think of a concept of a person rather than a person.

Bottom-up solutions to DP problems allow you, if the structure permits, to throw away parts of the full table. This is more memory efficient. Or, you could build the table bottom-up which avoids the repeated verification step in memoized, top-down solutions because when you reach an entry that isn't filled, you know that its related subproblems have already been computed and cached.

Someone posted an Euler problem with finding the maximal sum along any path (binary choice at each step) down a pyramid. The bottom-up solution only ever generates a "cache" of row elements (starting the row count from 1). The 100th row has 100 elements. When you go up to the 99th row you only need 99 elements by the end of calculating it, and so on. This is more efficient in memory than the n*(n+1)/2 (approx.) elements you'd need doing a top-down recursive, memoized version. Though in that case it's not awful on modern computers, it is a consideration for complex and large problems.

The bottom-up version also lends itself to not needing to bring the entire pyramid into memory, only one row + the cache at a time so you only have |row| + |row| + 1 items in memory at any given time (plus some temp variables or index variables). Again, it can be very memory efficient. Technically, you don't even need the entire current row in memory, only one element of it and then read each new element as you step across the row which further reduces the memory overhead.

With regard to building a full table, I realize Fib is a poor example in general but it is illustrative and fits in a comment. Let's say you memoize the naive version, then you have to include this check either before the recursive calls or at the start of each call:

if n in FIB: # either return if at top of the function, or retrieve rather than make the recursive call

This is unneeded if you build the table bottom-up:

def fib_bottom_up(n): FIB = {1: 0, 2: 1} i = 3 while i <= n: FIB[i] = FIB[i - 1] + FIB[i - 2] return FIB

Bottom-up construction of the table skips those checks which can add up for larger table constructions, or if you're building up many different tables. Consider a more complex optimization problem where different initial parameters result in different tables being generated (but by the same method). This bottom-up approach will be more efficient than the top-down approach.

Of course, a benefit for top-down is when an input only needs some subset of the table. If the generated table will be sparse, but may not be easily constructed in a sparse manner bottom-up, then top-down can be better.

I wonder why he cares whether or not people delete their DNA?

I asked them to delete mine (although I'm not optimistic that they did so), and I'm glad that I did for two reasons. First, I don't think they dealt with me transparently and honestly from the start and second, whether or not that data is directly a risk to me, it's yet more data about me that's out there in the world and can be combined with other data to make a potent risk.

The less data about me that exists in any database, even trivial or apparently innocuous data, the better.

It’s so weird that you’re like agreeing with me but then at the very end you say my promise is wrong. Can you pick a lane?

Currently prices are artificially low for AI in order to boot shop the market. Artificially low prices increase demand which increases environmental impact.

If you rewind the clock to an Uber launched in San Francisco you would see the exact same playbook: artificially low prices, bootstrapping the market, increase demand, and increase environmental impact.

Your whole premise keeps flip flopping.
by rscho | 2025-07-21 19:03:24+00:00
Look, he might use AI but I'm not. I also have 20 years in the field, and I've lost count of how many times I found myself alone with a risky patient. Yes, oftentimes people are just 10m away. Yes, that's not supposed to happen. But that's often far enough for us anesthesiologists to wish we'd be somewhere else. Perspectives and empathy matter. Try to put yourself in our shoes, sometimes. For the record, I'm the main hybrid MRI OR guy in my hospital, so I work near MRIs most days.
by fluidcruft | 2025-07-21 19:03:27+00:00
I don't understand your question. The anesthesiologist was describing equipment that was not safe to have in the room and was positioned outside the room to be viewed through the observation window.

Many sites screen individuals to accompany patients. It's fairly common in pediatrics.

If by "the above case" you are talking about the accident that happened, it has nothing whatsoever to do with anesthesia in the first place. It was an outpatient knee MRI performed without anesthesia at a free standing clinic (not a hospital). Based on the wife's description of what happened, the technologist brought her husband into the room at her request to help her up after the scan had finished and the technologist failed to screen him.

> When I first started at Microsoft, I had a sleeping bag in my office. I coded until 11pm nightly and slept until 3am, at which point I’d code until ~6am, then sleep until my first meeting ~10am.

It’s everyone’s pejorative on what they want to focus on in life, but this is pretty insane. Obviously it worked out for him (so we think), but this sounds like recipe for a couple divorces and kids that hate you (even if he eventually slowed down somewhat).

Yes, Lumafield does some of my favorite marketing ever. It adds more (absolute) value to the world than they receive back from it. Their monthly CT scans are some of my favorite small joys: https://www.scanofthemonth.com/

I mean, there's probably very good ROI on this marketing; I'm not saying they're foolish or selfless. Just that it doesn't cost them that much to do, so it's a win-win for everyone.

> Germany is famous for being cloudy and is much further north, much of it is north of the primary US-Canada border. It is one of the leading solar adopters

Looks like it's about 12 cents (in USD) more expensive on average per kwh in Germany than Cali

So maybe Germany isn't exactly a great example of energy production if it's that much more expensive

It's also how IT professionals navigate software interfaces!

I'm amused by the amount of flak you are getting here.

Being fast and efficient with any piece of UI of course means to replace navigation and discovery with memory and intuition, at least in part!

Not just keyboard shortcuts, also the placement of UI elements, latencies, learning quirky behaviors... being fast with software means not having to discover features.

Similar to labeled controls on a physical device, just in a simulacrum.

There are other five bit character sets as well, such as the 5-bit Baudot character set and the 5-bit Zork character set. You could also use variable bits characters, or other bases of numbers.

You can also use other decks, e.g. with tarot cards you will have 78 cards rather than only 52 cards, and can make a longer message.

Other comments on here had mention doing other things such as face-up vs face-down cards.

> if you don’t separate yourself from your work you’ll have no “you” when you dial back or become unnecessary or undesirable

I see this with a lot of people I know who retire and find they don't know what to do with their time. Work is all they ever really did.

I know another guy, well into his seventies, who is still working because there's nothing else he wants to do. He'll either die at his desk or in bed.

Bro doesn't know India lol.

I'm from one of the most influential families in my state in India (the most educated in the country by the way), a (former) member of the ruling party in the state and living in one of the better parts of my district. And even I was detained by police for "loitering in the streets at night" (I had a midnight craving after being inordinately starved and my city shuts down at 9 pm). The only reason I did not spend a night in a jail cell was because I called my neighbour who called some local political honchos (not even my parents because they are utterly useless in such matters). All so that the police could wring a bribe out of me (which I ended up not paying). Meanwhile in other streets, drug peddlers run amok.

India is not for the faint-hearted, even for many Indians.

Useful and interesting but likely still dangerous in production without connecting to formal verification tools.

I know o3 is far from state of the art these days but it's great at finding relevant literature and suggesting inequalities to consider but in actual proofs it can produce convincing looking statements that are false if you follow the details, or even just the algebra, carefully. Subtle errors like these might become harder to detect as the models get better.

It's all about security, especially for non-technical user.

The Chrome OS is running trusted boot and immutable partition, and completely closed host system, with no user-installable apt [0]. This means it's impossible to completely break the system - nothing that user does will escape browser sandbox. And, for defense-in-depth, even if browser sandbox got compromised, there is no sudo nor ~/.bashrc nor any other executable per-user configs, so malicious software will disappear after reboot. And if you compromise kernel and modify disk directly, there is verified boot...

And this is not just theoretical benefits, it's stops practical attacks. Are you sure that "bash | curl" command you typed was safe? Are you sure that "pip install" or "npm install" you did didn't actually install malware on your PC?

It is possible to build systems like this based on open-source Linux, but this will be quite a lot of work, and may even require separated trusted builder machine. Definitely out of reach of non-technical user.

I use it only for folks like you and other proxy red hats. I know what it means. Sorry I haven’t dedicated my days to pumping internet points on hn. I mostly lurk. I also know what that means. You and your ilk turn yourselves inside out to prove to ONLY YOU that you are righteous in your dogma. Always with the most vague and suspect “sources”. Your fear driven ethos and enlarged frontal lobe will hopefully be the end of you and yours eventually in public discourse. Until then, good luck.

> I was Facebook’s first engineer promoted to E9 outside the US. All this, at the cost of my second-grade son making sure he had a reserved spot on my calendar prior to me heading off to work that morning. Was it worth it?

> If you want atypically fast career growth, you need to put in the hours. Only you can answer whether the sacrifices are worth it.

Ask the kid. Or the spouse.

My father had a significant career: medical doctor with a PhD, yadda yadda. I won't go into the details, but he left much to be desired both as a husband and as a father. At the age of 54, while he was working on a second PhD, he had a stroke that nearly killed him and left him severely disabled until his death at 70.

Was it worth it? His surviving family doesn't think so. I think we would have all been happier if he had made different choices. His mistakes were a big part of why I quit working to spend time with my own family. Ask my spouse and children whether I made the right call.

I have done a fair amount of noodling around with the numbers and have come to the conclusion that within a decade, maybe two, we'll start to see rural homes disconnecting from the grid in significant numbers.

Or for new homes, not connecting to the grid in the first place. Around here, the cost of getting a new house on the grid is $50,000 - $100,000. This is often more than the cost of the land itself. That will buy a serious amount of panels and storage, AND you won't have to send a $100 - $200 check to the utility every month. (They will need replacing in a few decades, of course, but being energy-independent can still work out.)

I live in Michigan which is one of the worst states for solar. Full sun only half the time and fairly brutal winters, depending on the year. Yet I know people who get almost all of their electricity from solar. They treat the grid as a big backup generator. Some are just getting into it now and others have been doing it for years as a hobby. Of course there's more to it than just switching power sources. You need to think about insulating your home better, alternative sources of heat, timing when you run certain appliances, running some stuff directly off DC to reduce conversion losses, etc. But it's eminently doable. Which means it's a complete no-brainer for the southwestern states with plenty of sun and very little demand for winter heat.

My main concern at this point is that solar and batteries are cheap NOW, will they be in the future? It's hard to say. But my guess is that we might be at peak "cheapness" for solar, for a bunch of reasons. The federal subsidy is going away. Right now, solar panels and batteries come from almost exclusively from China, whose government has subsidized their low cost to prevent foreign competition. Even if they decide to keep producing them cheaply (they may not, their economy is not doing any better than ours lately), the new tariffs are designed explicitly to make them NOT cheap in order to favor US manufacturers (the few such that there are, one of which is Tesla) and indirectly, oil companies.

In urban/suburban environments, solar can make sense to offset SOME electricity usage in order to lower the light bill, but that's about as far as you can get for most homes. What little land is available is shaded by trees or large buildings. Roof panels work, but are a huge pain for panel and roof maintenance, and the roof should face south, and only so many can fit on the roof, etc. A rack of lithium batteries bolted to the outside of a house looks like a liability to insurance companies and may lower resale value. I still think the best strategy for urban environments is to force utilities (via regulation) to build out more solar farms to move the risks out of the neighborhoods, let the utilities handle all the maintenance and pain points, and take advantage of the economies of scale.

I might postulate that while Rhubarb LTD absolutely doesn't hold and will never create a backdoor, Celery Inc does. Ignore the fact that Celery is staffed by some of Rhubarb's senior engineers working part time. Ignore the fact Celery are contracted to do security assessments so have access to all the source code, radio firmware and schematics...

I absolutely don't actually know anything about Apple, but I've seen some of the ways even small companies legally split themselves up to avoid tax or various forms of liability. Multiple phone numbers to the same phone, multiple domains and email providers to the same laptop. Multiple denials that you've ever heard of the other company let alone happen to share the same office space...

There's a massive difference between a truthful statement and an honest one; anyone that works with code should understand that.

At what cost?

A career is just one facet of a fulfilled life alongside relationships, health, personal development and joy. Putting everything aside aiming for promotions may look like a success on paper but it often leads to burnout, loneliness and unfulfilled goals in other areas.

You can climb the ladder but if you ignore the rest of your life you may reach the top, only to realize once alone at the summit that your entire kingdom is in disarray.

Perhaps slowing your career can even be wise if the other spheres of your life are suffering. A sabbatical year or even a deliberate downshift can offer the space to realign and rediscover purpose.

There is something to be said about survivorship bias too, many who work hard don't achieve similar outcomes. We often hear from those who worked relentlessly and succeeded but rarely from the many who worked just as hard and didn't see the same results. For example, some studies show that nearly half of the women in tech leave the industry by mid-career, often due to systemic barriers

By original MIPS designers do you mean from Stanford? Those would include John L. Hennessy, Norman P. Jouppi, Steven Przybylski and Christopher Rowen as the authors of the first papers about the project. If you are talking about the MIPS company started by John Hennessy and Chris Rowen, Wikipedia has this list:

https://en.wikipedia.org/wiki/MIPS_Technologies#Notable_Cont...

In either case, I am not aware of any of them being RISC-V leaders though John Hennessy did rewrite the books he co-authored from DLX to RISC-V.

Hey all, member of the benchmark team here! The goal for this project was to see how LLMs well could do bookkeeping without an overly opinionated scaffold. We gave them access to processed transaction records and code execution tools, but it was up to them to choose exactly how to use those.

Claude and Grok 4 did reasonably well (within CPA baselines) for the first few months, but tended to degrade as more data came in. Interestingly, the failures aren’t exclusively a context length problem, as we reset the context monthly (with past decisions, accruals/deferrals, and comments available via tool calls) and the types of errors appear to be more reward hacking vs pure hallucinations.

Accounting is very interesting in an RL-first world as it is pretty easy to develop intermediate rewards for training models. We are pretty sure that we can juice the performance more with a far more rigid scaffold, but that’s less relevant from a capabilities research perspective. We’re pushing down this research direction and will see how it goes.

Let us know if you have any questions!

Short sighted to prioritize career over life. Few people in the US have any self-worth or identity outside their career, at least IME working in tech. It saddens me greatly. “Productivity” is a disease. Some of my closest friends have no idea what to do with themselves outside of work. No one lays on their death bed wishing they worked more.

The two approaches seem to serve different use cases. Mapping to a sprite-sheet (how FastImageCache describes itself) doesnt matter if images arent actually reused often (eg doom scrolling). But if you do tend to either reuse the same image or scroll up/down on the same content then yes it will come out ahead.

Ive seen a lot of async image loaders over the years on ios and for the most part they were all fine. The async offload and pushing remote url loading to the background is the most important part of what was historically missing from the first party ios api.

Given the age group (mean age of 71), I wonder if it's partly an effect of people with mild cognitive impairment, which the study explicitly mentions are included, being more sedentary (i.e., the effect is backwards or bidirectional). You could also imaging other risks of aging increasing both sedentary time and harming the brain (e.g., social isolation).

Where is "in Europe" in your case? There are around 50 countries, each with their own laws. In Finland, you don't get ANY vacation days until the next time April 1st rolls around. And then, the number of days you get is heavily reduced if you haven't worked the entire year from April-April. Why is it like that? Who the hell knows. Oh yeah, if you take 5 days off, it counts as 6 days. So you essentially have 5/6 of the days that are promised to you on paper.

Game Genie was likely the primary contributor of exposing kids to computer science in the 90's/00's, especially with "63" or "FF" appearing in every Infinite Lives cheat code. The "wow" moment for me was a Encounter the Specified Pokemon cheatcode for Pokemon Red where the specified Pokemon was their ID in hexadecimal.

Once I got a GameShark which included a VHS on how to create codes with the GameShark (identifying which memory addresses change and how to fix them to a specific value), and admittingly that may have scared me off of the computer science path.
