Probably not. Position of the antenna relative to the ground plane alters the radiation pattern. That’s why you’ll see police cruisers mount their antennas dead center on the roof—it creates an omnidirectional pattern. Mounting it to one side or another causes the field to radiate more in the direction with more roof in front of it (kind of the opposite of intuition). So the remote in your hand still likely interacts with your body, but not in a controlled or desirable way.

I liked their idea, and I think it had a lot of potential for clever optimisation. Shame about the bankrupcy. But it's different to what I'm talking about. Tabula's extremely fast multipexing needed a lot of chip area.
Nobody needs 10 hours to learn how to make coffee with a coffee machine.

On the other side, each of us spent years learning other stuff before being allowed to touch a coffee machine.

AIs do learn in a different way than we do and yet it's not clear if they are less or more efficient than us, for the things they can actually do well.
I've not bought a new computer in decades. The only non-retro thing is adoption of SSD storage where ever possible. It's such a cheap way to radically improve the performance of old computers.

For fun, I've got Termux on my Motorola G Power 2021, my first Smartphone/magic glass slab. In that folder, I've got SimH compiled, and a Vax 11/780 that I emulate, running OpenVMS 7.3. Telnetting into it from my laptop is a fun exercise in retrocomputing.

As far as going retro goes, I've got a friend I help restore old electronics. I've learned to hate Silver Mica capacitors. I'm starting to not jump when smoke or sparks come out of them. The odd thing is that on old (1940s-50s) technology, smoke coming out isn't necessarily a death sentence... stuff still works after that. We recently got a 1947 TV set going. We've done all sorts of things including radios, ham gear, and Cesium Beam atomic clocks.

I've you've got questions about old electronics, I can probably get you an answer.
My buddy just installed a dc hybrid system and it’s been pretty much amazing. He’s in a warm climate with lots of sun though, but the idea of plugging panels directly into solar panels on hot days makes so much sense.

Are you in a cold climate? My biggest concern is installing splits in very cold mountain climates (my use case).
Heat pumps are culture wars now, believe it or not.

https://www.telegraph.co.uk/money/net-zero/why-heat-pumps-wi...

DT article to illustrate, not necessarily to inform. The idea I believe being that heat pumps are part of a supposedly unnecessary and costly push to Net Zero driven by industry and shadowy interest groups but which are just another means of a) enforcing control and b) screwing money out of 'the little guy' and siphoning tax dollars off compliant governments. And thus one is able to wave away an article absolutely bursting with scientific detail and research as 'well, it's all a bit convenient, isn't it?'

I honestly despair.
Ouch! It is going to take a lot of work to get Polars this fast. If ever.
AI bubble only exist because search sucks. Remove the novelty of chat, and it is nothing but a filter on bad search results.

Google will hopefully reinvent search for post-AI. IF AI is search, AI is indexing. and they are good at it. All the others are using stale data, which won't cut it besides lame limited assistants for specific use cases.

but yeah, more likely they won't do anything good in the end.

Dataframes and SQL have overlapping functionality, but I wouldn't say that dataframes are an "alternative" to SQL. The tradeoffs are very different. You don't have to worry about minimizing disk reads or think about concurrency issues like transactions or locks, because a dataframe is just an in-memory data structure like a list or a dict, rather than a database. Dataframes also aren't really about relational algebra like SQL is.
Dogs are mammal, come from social wolves, dogs live in complex human social structures, so on the other hand, it's likely their emotions are not extremely different to our own.
Couldn’t you say the same for e.g. JavaScript? The variables aren’t typed there either and prototypes are mutable. I could definitely see things being harder with Python which has a lot of tricky metaprogramming available that other interpreted languages don’t but I don’t think it’s as simple as a lack of explicit types.
> which includes the unjustly neglected data.table

So so true.

I was working on an adhoc project that needed a quick result by the end of the day. I had to pull this series of parquet files and do some quick and dirty analysis. My first reflex was to use python with pandas, quick and easy. Python could not handle the datasets, too large. I decided to give R and data.table a go and it went smoothly. I am usually a python user but from time to time I feel compelled to jump back to R and data.table. Phenomenal tool.
This has far less to do with an AI bubble and far more to do with the fact the US has a lot of very high margin, relatively high growth international businesses.

These companies are richly valued primarily because they make massive sums of money and all seem to have bright futures. It's hard to find companies with characteristics like that (if they exist at all) outside of the US.
The arbitrary vs fixed precision people are also totally clueless.

All of the arbitrary precision papers should have been rejected. This is CS theory 101. Any non-trivial architecture is not just Turing complete, it can perform hypercomputation (solving the halting problem), if it can use arbitrary precision numbers.
Eh I guess it’s supposed to be water cooler talk for startup founders. The vibe would be different if people stuck only to what they know. We all know we’re ignorant, but it’s more fun to be interestingly wrong than boringly correct.

I feel like any learning is sort of a bonus.
I just write Swift, every day (like, seven days a week, 52.4 weeks per year)[0].

It certainly seems to help me to be very productive. I am not as advanced as Swift scientists and academicians, but I speak it without an accent.

As far as automating everything; I automate some stuff, but not that much. If the act of doing the automation teaches me something, I guess that's good.

However, automation often encourages a "Greatest Common Denominator" approach to things that may be best served as hand-crafted, artisanal work. An example is what I'm working on, right now. I'm preparing an app for App Store release, so I have to do a whole bunch of screengrabs and videos. It's a big fat pain. Many shops automate this.

But I am also carefully choreographing the process, and ensuring the best Quality for everything. The App Store page is incredibly important to branding (something many techs don't take as seriously as they should, IMNSHO). It's worth it to spend as much time as possible, working on it. I only do this, every now and then, so it's not really a big deal.

Right. The same company that said "You're holding it wrong" when there was a design defect causing calls to drop out. The same company that shipped a broken keyboard and refused to repair units until losing the ensuing court battle.

But sure, they just only have the users best interest at heart. It is confusing that you write it, when you understand full well that no rational person will believe it, I'm not even convinced you believe it.
And don't forget that each git clone can have multiple remotes.

Some kinds of complexity are more fragile and easier to maintain than others.

Active flow control systems benefit from the fact that any individual valve has very little effect on the flight characteristics of the aircraft, making achieving high redundancy much easier. Also, the moving parts will be much smaller, and so easier to replace and maintain.
Carnot limit has nothing to do with heating efficiency, only with converting heat into mechanical work
Which russian role model would you recommend instead?
https://news.ycombinator.com/item?id=38925695
incorrect, the carnot cycle is reversible (like everything in physics up to cp reversal, except for entropy increase), so it also has to do with converting mechanical work into heat (differences)

specifically, in this case, if you convert a hypothetical 2770° flame into mechanical work in a hypothetical heat engine capable of withstanding it, you can use that mechanical work to drive a heat pump to pump ten times as much heat into the house to heat it up to 30°. or more, if the temperature outside is higher than 0°

It never occurred to me that the remote location could be a file path!
Short range isn't necessarily bad. Modern cars unlock automatically if you try to open the door while the keyfob is in range, so long range could mean someone could unlock your car while you're out of sight.

I don't know if that system uses the same range as when you press the button on the keyfob, but I have read about a hack (probably here) where thieves used a transmitter to extend the range of both the car and the keyfob to unlock the car while the owner is out of sight. That's easier to do the longer the range is.
It took decades before there was finally the evidence we have today of the social impacts of leaded gasoline.

Sometimes problems have such a broad scope that the impacts are normative across samples and analysis is very difficult.

For example, we know something is at fault for why developed nations have such high and growing autoimmune diseases compared to less developed nations. But specifically what the culprit is eludes us.

An argument from silence isn't a very compelling argument for the safety of microplastics.
More than 10 years ago I spilled miso soup on a 2010 MacBook Pro on my first day moving to Japan. I took it apart and cleaned it but the keyboard and trackpad couldn't be saved. Some keys always sent a signal and it would only boot into safe mode. But I could disassemble the laptop, turn it on, and remove the keyboard connector and then use it with an external mouse and keyboard. I did that for about a week until replacement parts arrived. I fixed it and the MacBook still works to this day.
In my dream it's a nice MicroVax or 68000 series CPU with at least 16 registers and a built in floating point unit. Not a Z80 or 8088 derivative.

Online clases are bad because you can not go to each desk to give a personal advice to each student :( . At 18-25 years, most of them are not mature enough to learn alone.

My sugestion is to have the official long list of exercices, but also have an official 1 exectice that each clas, and waste 5 or 10 minutes showing that exercice (In a blackboard I'd sugest writing it. In a online class, just read it aloud slowly.) They are 5 wasted minutes, but that gives a strong impression that the crazy guy in charge of the class cares about that exercice. Remember to waste another 5 minutes asking for the solution of the exercice next class.

Generally a fan of heat pumps but the big issue remains where does the electricity come from to power them. Burning coal or gas to make electricity to power a heat pump isn’t great. Cost wise too I know a bunch of folks that switched from gas to electric heat pumps only to be shocked by their electric bills.

Highly efficient natural gas setups remain much better for many settings.

> The point is that ants don't comprehend any other animals, neither those more nor those less complex than them, nor even those as complex as them (beetles). In contrast, we have at least some comprehension of all other animals on Earth that we've found. So, there is a fundamental difference between us and ants that makes the analogy not likely to hold.

it is really important to establish some sort of vocab to ensure that we are talking about the same thing here.

By comprehend I mean you, as an ant, "understand" a bug in a sense that you can predict its movements, eat it, force it to go away, or breed the thing if you find its symbiotically useful, in a sense you have internal world model of a thing, comprehend.

hence, ant in a strict sense, does not comprehend humans, it doesn't have world model of us, as a thing. most that it can do, it can see us as a force of nature
that somehow happens to it.

on the other hand, we understand it almost perfectly, we can play with them, be benevolent, or malevolent toward their entire "civilization" we can joke with then playing with their communications, we don't get everything but we understand the gist of it.

> It's far more plausible we could have some comprehension of even a very advanced civilization than not. For us to not be able to comprehend them, they would have to entirely be using physics we don't understand at all. Not physics we know + physics we don't, but only physics we don't know about. Which, given how much of low energy physics we understand to great deals of precision, seems extraordinarily unlikely.

no, just no. it is pure speculation, we think too much of ourselves.
Amazing! Anything else you can share? Tutorials that you used? Your process? Anything? I always wanted to play around with something like this, but I feel I'm missing even the right starting point
Tap water through a charcoal filter to a stainless steel all-metal bottle works wonders and costs almost nothing a year — we love it in our house.

The issue with global warming doomers is hyper exaggeration. It divides people into doomers and non-believer camps.

The reality with global warming is somewhere in the middle. It’s a slow boiling problem. We won’t be all dead but billions of people will need to adapt to new climate patterns.

CO2 spiking from ~280 parts per million to 400+ parts per million is a provable fact measured independently by many labs around the world.

https://blog.csiro.au/co2-data-twitter/

The science of global warming - aka CO2 and H2O capturing photons from the sun in infrared spectrum and heating up is well known physics. Experiments can be done at home.

If an asteroid hit earth like when dinosaurs were around, humans would still make it through - it would be very painful. The world would not end.

Gasoline is not the enemy. Most countries don’t like that they have to import from Russia, Saudi Arabia and the likes. The fact is gasoline is a cheap, semi-abundant, portable, energy dense, relatively safe fuel. We got nothing better atm.

Batteries are a start but to be competitive with gasoline, they need to be cheaper and >10X more energy dense.

The fact is we haven’t cracked high efficiency artificial photosynthesis at scale. Capturing CO2 + solar energy into energy dense hydrocarbons.

Our bottleneck is human ingenuity. We ought to be pouring more resources into cracking what nature has been doing for millions of years.

Nvidia is clearly riding the AI wave, but on the expectation that the demand for compute will keep increasing.

As for Tesla, I thought the general consensus was that they are behind cruise, who are far behind Waymo on self-driving?
Or you can just burn it at 2000C and convert all that heat into... well, heating. The initial claim was about using 2000C flame for heating as somehow wasteful, which it clear is not.
"How To Be A Pandas Expert"[1] is a good primer on dataframes. There's a certain mental model you need to use dataframes effectively but it's not apparent from reading the official docs. The video makes it explicit: dataframes are about like-indexed one-dimensional data, and every dataframe operation can be understood in terms of what it does to the index.

> The iPhone 12/13 Mini was substantially smaller, but few people bought it

I knew before scrolling down that such a comment would be there.

an iphone costs easily 5x-7x more than an android phone. Most people just want a phone that can do messages, calls, and has a gps. There haven't been any non-overpriced smaller smartphones lately.
Exactly, it is always making me angry when iOS proponents are trying to tell me not to use the App Store. I wish I could!

Mammography AI can cost patients extra. Is it worth it?
One under-explored option with radiation resistant electronics IMO is to scale it up for robustness. It's impractical if we want to launch it from a gravity well, but if it could be built in space, there a lot of space, in space...

Also, the processing needn't be fast at all if going vast distances. There's a lot of time to complete a calculation. Lot's of time and lots of room for redundancy. Same with fuel, yes the rocket equation is wicked, but if you could just get more of it from an asteroid or whatever, just get more of it. Huge, slow burners with "CPUs" a mile wide.
Update: just had a call and it's a hack that voids warranty. There are units with built in heaters. Picking an AC is a nightmare with OCD :/
There've been a few, but the first one that impacted me was Chrome's switch to requiring the SameSite=None flag on Set-Cookie headers[1] in a third party context.

> Warning: A number of older versions of browsers including Chrome, Safari, and UC browser are incompatible with the new None attribute and may ignore or restrict the cookie.

This caveat meant that UA sniffing was the only reliable means of setting cookies that were guaranteed to work properly.

> Namely, you burn the gas in the home, and use the temperature gradient to also run a heat pump vs the outside.

I am not exactly sure what that would look like, but I'd imagine it would at least be difficult to match the efficiency of a combined cycle power plant to generate electricity at home for the heat pump. Then again, as you say, you would have the "waste" heat locally to harness as well. Although this waste heat in power plants can be used for district heating as well, so it might also be used in that situation.

Anyway, my main point was that the sentence "heat pumps make much more sense when you don't burn things to power them." makes it sound like burning the same thing to heat your house directly was more efficient when in fact it is not, and potentially by a pretty wide margin.
OpenAI’s claim that it got the content from third party sites raises an intriguing twist to this copyright equities problem that at least I haven’t thought about.

It wasn’t clear from the article whether that “third party website NYTimes content” was authorized or not, but as a news reader I know first hand NYTimes syndicates its content to a ton of other (local but even big city) newspapers which may not have the reporters/skills, or scraping defenses of NY times, and whose sites and citations almost certainly do not have clear metadata on who the copyright holder is. I wonder if that’s part of the problem.

OpenAI makes it sound like it’s not their fault, they would abide by NYTimes wishes if they would/could, but their business model and technical architecture cavalier/dependent being allowed to copy others’ content. Their engineers have prioritized either technical glory of building AI .. or avoiding existential risks… but have not (yet) apparently done the ethically appropriate work of determining copyright and licensing ownership of content they use. That’s an annoying AI problem, of the unsexy kind, an anti-hacker thing to do but potentially the right thing to do. (Otherwise it’s just glorified techie plagiarism, right?)

So much of this is a recapitulation of themes from early search engine days and the thinking thereafter (“code is law”). I am pulling out the popcorn and interested to see how it shakes out.

On an only slightly related angle, if a NYTimes article is syndicated on a thousand other websites, does its word frequency/adjacency/etc rating get more heavily weighted in the model and how does OpenAI control for that? Or is that a feature, not a bug? In either case, how will does that fit in the architecture of control of this new system… or what does it imply about its eventual abuse/manipulation by spammers?
Nevermind, it has it but it's under Computation in polars.Series.diff and I was looking under Aggregation. This is great.

For instance you've got a time series with an odometer value and you want the a delta from the previous sample to compute the every trip.
It might be useful to have LLMs do automoderation on forums, tweaked by the moderators to shift the discussion the direction they want it to go. Have it so that the feedback is immediately on pressing the submit button rather than after-the-fact. And probably with more useful information to the poster than the "our users don't post messages like this" message.

I think it'd be useful to ban pun threads and other low effort shitposting, but it would probably have issues determining actual expertise from faux expertise. With the wrong settings it would be frustratingly useless, but over time some useful defaults should emerge.
I flat out never trust any numbers from startups. Some companies are still using the SaaS 10-13x revenue as an estimation, despite the current economic climate and often in spite of a) not reqlly being a SaaS and b) not growing that fast.

Throw in liquidation preferences, etc. and it's not really possible to know anyway. I've been at three startups. Two were acquired and one is still plateaued over 10 years after I left. Total value of my stock so far? $0.

It'd have to be some rare unicorn for me to treat startup options as anything other than a lottery ticket.
very correct, because we are talking about using high temperature flame as somehow wasteful when used for heating. How does converting heat into mechanical work even enter equation?
Painting the equations as you go will increase brute forcing . I think it's beter to keep them in the same color.
