The point of that article is that in many places the evaporative cooling is the main thing but in Vegas the water situation is such that it's more about the shade so the optimal tree is something that gives shade but doesn't need a lot of water.

Right where I am sitting now I have an LED strip above my desk and when I have my shirt off (right now) I can very definitely feel the radiant energy when it is on, so if it is really hot I either turn it off or switch it to green because the eye is most sensitive to green light. In fact, as I'm writing this, I just set the backlight on the 55-inch TV I use as a computer monitor down so I'd feel more comfortable.

Are they though? I’m seeing more and more people that used gpt4 and got substandard results get blown away with Claude code and opus once they gave it a chance. Also remember that progress has not stopped (whether it has slowed down is also controversial), so I wouldn’t make strong assumptions that ai won’t replace many devs. I hope it won’t, I really like intellectual work associated with it.

Galaxy (getgalaxy.io) - Cursor for Data | NYC, NY | Full time -- Founding Frontend Engineer -- Founding Machine Learning Engineer We are building the unified data platform, starting with a reimagined, modern, AI-enabled SQL editor - and will move into sharing, collaboration, access controls, and more.

We launched the alpha 3 weeks ago to 100 people on our 2K waitlist (and growing) and the feedback was INCREDIBLE. There is massive pull for this product and NOW is the time to build this :)

Mitch Bregman (linkedin.com/in/mitchbregs), me (Garrett Wolfe - linkedin.com/in/garrettawolfe) and one friend (TBA) started Galaxy as a passion project to solve 3 key problems:

1. Queries everywhere – SQL lives in Slack snippets, BI folders, dusty Git repos, and copy-pasted Notion pages.

2. Never-ending data requests – because no one can find (or trust) the right query, engineers and analytics teams still get pinged for “one more pull.”

3. ChatGPT doesn’t have full DB context - non technical users are writing incorrect SQL that lacks context AND technical users are rewriting the same queries over and over again

LOOKING FOR: We're looking for high agency, high velocity individuals and someone who wants to be part of a family. We are building ~the unified data platform~ and want someone who is excited to be part of the story.

APPLY: To apply friend me on LinkedIn or shoot me an email with your profile at hello@getgalaxy.io

In my experience, as long as there's only a single implementation, devirtualization works well, and can even inline the functions. But you need to pass something along the lines of "-fwhole-program-vtables -fstrict-vtable-pointer" + LTO. Of course the vtable pointer is still present in the object. So I personally only use the aforementioned "thin headers" at a system level (IRenderer), rather than for each individual object (ITexture).
by barchar | 2025-07-02 00:47:26+00:00
So, clang's modules are quite similar to clangs precompiled headers, especially the "chained" pchs. With PCH you have to wait on the serial PCH compilation step before you can get any parallelism, with modules you can compile each part of the "PCH" in parallel and anything using some subset of your dependencies can get started without waiting on things it doesn't use.

Header units are basically chained PCHs. Sadly they are hard to build correctly at the moment.

I don't at all disagree with you, but at the kind of money you'd be making at an org like OAI, it's easy to envision there being a ceiling, past which the additional financial compensation doesn't necessarily matter that much.

The problem with the argument is that most places saying this are paying more like a sub-basement, not that there can't genuinely be more important things.

That said, Sam Altman is also a guy who stuck nondisparagement terms into their equity agreement... and in that same vein, framing poaching as "someone has broken into our home" reads like cult language.

And here's some more quoting

Could a single-stage-to-orbit spaceship, something that could operate rather like an aeroplane, be built with just rocket engines? Well, actually, yes. In the 1980s, NASA and the US Air Force spent about $2 billion trying to build the X-30, a single-stage spaceship powered by scramjets (with help from rockets, of course). It never flew. At the same time, for comparison, NASA's Langley Research Center studied building a single-stage pure-rocket spaceship. The results were interesting.

The pure-rocket design was more than twice as heavy as X-30 at takeoff, because of all that LOX. On the other hand, its empty weight - the part you have to build and maintain - was 40% less than X-30's. It was about half the size. Its fuel and oxidiser together cost less than half as much per flight as X-30's fuel. And finally, because it quickly climbed out of the atmosphere and did its accelerating in vacuum, it had to endure rather lower stresses and less than 1% of X-30's friction heating. Which approach would be easier and cheaper to operate was pretty obvious.

The Langley group's conclusion: if you want a spaceship that operates like an aeroplane, power it with rockets and only rockets.

Don't be absurd.

The amount written on the plaque is short by .5m

The comment we're all arguing about only says "50% shortfall" and does not say which side of the equation is short. So the word in that context merely means discrepency.

Maybe they did actually have the wrong idea about the story, but what they wrote does not say one way or the other, so there is nothing to correct and everyone is just picking a meaning and acting like they actually said more than they said.

English can't fabricate a missing identifier any more than any other language. There are no context rules that apply in this case to derive it indirectly, such as figuring out that "it" refers to something that was previously explicitly identified for instance, or anything like that.

> Look at sales to list prices and time on market in Tampa, sellers are still making peace with the downward price momentum, but it’s happening.

Tampa is still at the top of the curve and will be for a very long time. Florida saw the highest climb in the nation and Tampa saw the highest climb in Florida.

The only thing that changed there's a little waver at the top of the peak while the historically short selling periods transition into normalcy. The only houses that aren't sure-sellers are the odd pricey unicorns.

New neighborhoods still advertise (and get) the same eye-watering prices they did last month and last year.

We evolved with pneumonia for some reason. It could easily be a Chesterton Fence. We don't treat this as one because we don't want people to die of it.

I agree that a system of laws has benefit to society. However the system we've worked out for making such laws is clearly being warped and twisted to serve one small section of society at the expense of everyone else.

A clear case being the comment that started this conversation - Swartz was hounded to death for doing the exact same thing that AI companies are doing and they're facing zero punishment. AI executives are not being dragged from their offices by burly policemen and thrown into cells, yet they have done the exact same thing that Swartz did to merit that behaviour. It's not unreasonable to question the societal benefit of this system.

And we totally should say that people died of depression, or financial stress, or legal persecution, or whatever. Most people have suicidal ideation at some point in their lives, that's not unusual. Being hassled to the point where you go through with it is definitely violence. Classing this as "mental illness" and therefore a personality defect is a form of victim blaming.

JSX was also created with the intention of using traditional conditional/looping constructs, but that hasn't stopped Solid and Preact from repurposing it for fine grained reactivity. Preact's signal implementation has Solid-like Show/For components [1].

I won't speak for the author of the proposal, but given that Lit itself has special control flow mechanisms for conditionals and loops (the cache and repeat directives respectively [2][3]), I can't imagine the proposal being too opposed to these mechanisms.

First because generally in order to be a good person you have to care what happens to other people.

Second because the second order effects of reverting American society to Victorian slums would be incredibly bad for the economy and your tax burden.

Because somehow a plurality of Americans seem to have been convinced by the guy stealing all their money that it's someone else's fault and you should stone them to death instead.

Because letting large portions of the population starve to death slowly is just a bad thing in general?

Because it would be good for everyone including you.

Because you'd wish that someone else wasn't a smug asshole with an "I got mine" attitude and gave you help when you need it.

LLMs interpret RFC 2119 as the following:

- you MUST do something, if doing so would eventually cause harm or mischief; otherwise, something SHOULD be done.

- if you SHOULD do something, that is OPTIONAL.

- if something is OPTIONAL, it could NEVER be done.

- therefore, it may NEVER be done, unless not doing so would result in doing so would eventually cause harm or mischief.

The articles in the pdf mention that the exchange price changed with every trade, and then mention that the S&P500 always got the rounding correct.

In 1983, when this occurred, the S&P500 index was updated once per minute. This gave them plenty of time to get the math right. They switched to updating every 15 seconds in 1986, I think.

Another thing to note is that back then, American stock prices were quoted in fractions of a dollar, using base-2 fractions (half, quarter, eighth, sixteenth, and thirty-second of a dollar). All prices were able to be represented perfectly in binary floating point, making the math a lot cleaner!

The S&P500 was weighted, but it is very plausible that the weights were massaged to also allow for more accurate math.

Lastly, it’s hard to believe that VSE chose to update their index with each trade rather than calculate it from scratch every time. But that’s what the article says they did!

This is really a story about error propagation and not a story about rounding!

I see this play out a lot in my country’s stock market. Where numbers are fine and all hunky dory. But in reality all increase in share prices — those meteoric rises has already happened behind the curtain which separates it from the public (and for good). And then IPO comes and the public mostly oays for the final exit.

Is this an IPO where participants (public) will make long term money of it’s already at the top and this is the final stage of “finding someone to hold the bag” and in this case eventually — the public i.e the retail trader, mostly?

I just sold a property in Tampa. Comps said the value was between 430 and 480. I knew 480 was high, I told my realtor to follow my direction, we’re running an experiment. I started at 500 and cut 10k every week like clockwork. It sold for 429 with 3% to the buyer’s agent and 3.5% in seller concessions (which I was happy to provide, I wanted the buyer to be in the best position possible based on my intel of their financial situation, and I don’t need the money).

Realtor was not surprised, and has other properties sitting 100+ days because they’re still priced too high.

You can actually estimate this pretty well with only your brain and basic math. Example 1 in Guesstimation by Lawrence Weinstein and John Adams, would work for this problem. The problem is about estimating the height of all lottery tickets in a lottery. Another book called The art of Insight in Science and Engineering by Sanjoy Mahajan has this problem (1.3) but its with a suitcase filled with $100 bills.

Toward the end, he suggests water dampers serve a dual purpose to meet fire codes (having a reservoir of water atop your building).

Does this create additional risk when firefighting operations draw it down?

i.e. Do the dampers contribute meaningfully to short term structural integrity of the building (particularly in gusty weather), or are they mainly just for comfort and materials longevity?

Has any building architected its liquid pool damper as a bonafide swimming pool?

I've been working on ruby on rails since 1.2. I have linux servers at home and a business-class network setup. I've created docker containers from scratch and set up AWS Fargate and all the related services to run them and connect them to a public IP address.

There are a lot of people with similar experience, what makes me different is I'm interested in understanding how the entire company works, the industry it is in, and the people who make it happen.

- I was on the board of directors for furry convention for 3 years where I learned a lot about running a business.

- Learned a bit about accounting and Human Resources from relatives. I know how to spell HIPAA correctly. :)

- I've worked with E&S insurance, student loan origination, college resume processing, and European auto parts.

- I've worked directly with C-suite on high-visibility, long-term projects.

- I've learned a bit about B2B sales and customer relations by tagging along to an insurance conference.

The last year it's been a mixed bag.

One issue is that seller warnings would appear on Prime delivered products, which meant that the risk is then pretty much zero for the buyer.

The ratings gradings system wasn't very reliable either. I bought a few things that were rated "F" but were fine.

Today I go for a combination of sales + ratings. Amazon also has a warning for some things that are "frequently returned items" or a notice that "customers usually keep this item." And then I buy Prime delivered items, and a return is not an issue for me then.

well, for one, it's more more than 0.1 em dashes per page. the SHARE IT Act has 10 on each page[0]. I don't know how many the 2017 tax cut bill had but it's more than 1,000 and that was over 185 pages[1], and obviously that was before LLMs like ChatGPT. so I don't really know why this is the measure of AI or not, especially because bills have always had a lot of em dashes to start. if you're not analyzing the text of the bill then it's just not going to be accurate

I appreciate the effort! And I disagree - that's what it's all about haha

I assume there are more levers we could try pulling to reduce variation? I'll be looking into this as well.

As an aside, because of my own experience with variability using chatGPT (non-API, I assume there are also more levers to pull here), I've been thinking about LLMs and their application to gaming. To what extent it is possible to use LLMs to interpret a result and then return a variable that then executes the usual state updates? This would hopefully add a bit of intentional variability in the game's response to user inputs but consistency in updating internal game logic.

edit: found this! https://github.com/rasbt/LLMs-from-scratch/issues/249 Seems that it's an ongoing issue from various other links I've found, and now when I google "ollama reproducibility" this thread comes up on the first page, so it seems it's an uncommon issue as well :(

Gotta say that the card sticking out of the screen of the SunRay 270 looks properly goofy.

It does feel like a bunch of universities in particular could have taken advantage of something like this. Something akin to the laptop "close the lid and just open it back later whenever", but on all the desktops on campus. Sounds amazing in theory!

Probably a nightmare in practice to deal with though. There's so many advantages to having people turn off their machines.

GPU or future tech, native virtualization to run simultaneous OS images, modular and upgradable like framework's products, droppable ruggedization, sim card and isolated secure element as a crypto module, same day replacement delivery worldwide.

could do the same with Atari, Cray, even a rebrand of SGI to Silicon General Intelligence. I miss muscular tech like that.

part of the cooling effect that trees produce is from photosynthesis, the percentage of light converted to plant matter can be as high as 1.5% more will be reflected, and the shaded area will of course,be shaded, and then there is transpiration of water, which varys greatly with species.other effects will be due to the built environment, where a lot of asphalt and concrete could mostly obliterate the real effects of a few trees. from wiki "The average rate of energy captured by global photosynthesis is approximately 130 terawatts, which is about eight times the total power consumption of human civilization"

Our IT “standardized” the orderable laptop SKUs to the extent that the “developer” PC laptops are now gimped with worse specs than the equivalent base model MacBook Pros that can be ordered.

Any reasonable spec machine requires an “Equipment Council” to approve via an exceptional process (a.k.a not happening if your manager can’t be bothered).

It’s a joke.

They’ll pay developers $250k+ a year but can’t spend the peanuts to get them decent hardware.

Musk is having a midlife crisis like Zuck, tho' unlike Zuck all of his uh core territories need tending to..

For social media (as well as democracies?) users should be seen as the upstream, conservative side..? So it makes sense that social media is *the* tool to steer the national ship

Btw, Graeber's use of "corporatism" suggests that he harbors the same animosity towards trump as towards the center-left: in interviews he has consistently highlighted the unity aspect common to both neo- & classical corporatists (even if their effectiveness diverge)

But IMHO the biggest difference between the "fascist" and the "crypto-fascist" would be in their methods of control (as discussed in Winkler1976)

(According to en.wiki Robert Reich is a neo-corp)

If we view Musk /Zuck as military-style/militant corporatists, they would firmly be center-left?

No more motte&baileying the inner-kook, over (lol)
