This isn't true. The requirement is just that new constructions are ready for electric appliances. It doesn't ban natural gas.

> A draft code update released Thursday by the California Energy Commission would require new single-family homes to be equipped with circuits and panels that would allow them to be powered by all-electric appliances for heating, cooking and drying clothes.

> The new code would not prohibit natural gas infrastructure, a step many environmentalists would like the state to take. But if the draft is ultimately authorized by the commission this year, it would require new homes to be “electric ready,” meaning they’re prepared to be transitioned away from gas appliances if any are used initially.
This is the one that specifically discusses telescope array (but your formula is still correct) https://en.wikipedia.org/wiki/Angular_resolution#Telescope_a...

60GHz has a wavelength of 5mm. Effective diameter would be ~13000km. Someone check my math but I end up with 5e-3/13e6 radians or ~.0001 arcseconds. Hubble is ~.05 arcseconds.

You can use a peeled-apart DVD and a USB web camera for a fraction of the cost. It's a design Public Labs came up with around 2012: https://hackaday.com/2012/08/27/turning-a-webcam-into-a-spec...

Public Labs even developed a modified design that works with most smart phone cameras, among their follow-up work (such as testing high-end cameras: https://publiclab.org/notes/stoft/10-23-2016/high-rez-webcam... )

The spectral response of the sensor is not linear, as it is designed to imitate human vision - and as anyone who read early 2000's digital camera reviews can tell you, even fancy cameras from well known manufacturers can have noticeably different color response.

One benefit of Rasp Pi cameras is that genuine cameras could be evaluated and characterized, but counterfeits and such will be a problem. Same is true of USB web cams, I suppose.
I guess I'm just curious as to what would compel someone to be so pedantic about something like this, unless they're just that willing to go to bat for a company who is obviously discriminating against these groups.
I did math and physics competitively and all the exams are very easy to access online, which meant that questions were generally "new" each time. It's interesting to see this not be the case…I honestly can't understand how this would reasonably work, because the people who were good literally kept copies of all the problems that they did, so a cottage industry of past tests would inevitably exist anyways.

Looking more closely at https://in-the-sky.org/spacecraft.php?id=45203 - that makes sense. Its released right about 350 km in a rather eccentric orbit which is then stabilized at just under 400, then after about a month there, it climbs to its target orbit over the course of a month up at 550km.

A more natural one is https://in-the-sky.org/spacecraft.php?id=45229 which has the same initial orbit pattern.

The key thing with this is that without anything else, the satellite has a lifespan that is measured in months to years and up to a decade... not centuries. A Kessler syndrome at 550km would certainly be rather up there on the "suck" scale, but wouldn't keep humanity grounded for more than a decade.

One of the important things to remember about debris at a given altitude, without additional energy, an object cannot climb further out of the the gravity well into a higher orbit. It will always come back to the same spot in its orbit one orbital period later.
They did?!? Please excuse me a sec, while I go uninstall that shit...
It still floors me to see such bearish opinions like this. It demonstrates how intelligent people can be completely wrong about the future, and it signals how early we are in the adoption curve for crypto.

The ability to print money and misrepresent the value of the dollar (i.e., CPI, GDP) combined with incentives for personal enrichment should be evidence enough that government-controlled currencies is not the scalable solution we thought it was.

We're about to experience inflation like we've not seen in the US in a long time and the resulting transfer of wealth and increase in inequality will be a catalyst for the adoption of crypto.

I hope to see you all there.
If I recall correctly, Saša Jurić mentioned in an interview that he envisions the BEAM being used as an OS in the future, where you can run your database, web server and other services under one VM.

While I don't personally have much use for it (at the moment), I'm curious about how this would look like with Lumen [0] where you can run your whole web stack with a single binary and being internally supervised by the BEAM.

Lumen's development has been slow but I remember seeing a tweet from a team member stating that development is slowly ramping back up (not a criticism in any way, just providing some context).

People always complain about the downsides of all these blue areas but at the end of the day there is still a massive population that continue to live there. For example: Exodus from California is mainly limited to people making less than 100k a year. People making more than that actually increased their population in California. So this is mainly a rich vs poor issue. I'm excited at the prospect of transforming some of the rural states into a mindset of progressivism. It will help prevent some of the gridlock that is holding back the country from trying big bold ideas.

It's all about cost. The assembly and test is the "low tech" part of semiconductor manufacturing and can be done well in Asia by workforces that are not as highly educated as those you need to run a fab. US and western economies have always focused on doing the highest value add portions of manufacturing domestically (where the highly educated workforce is key) while outsourcing the lower value add (lower margin) portions of the supply chain.

Consumers demand low cost. Many times they just buy the cheaper widget, because most people are not even capable of distinguishing the differences in performance or quality between two different widgets. But the difference in price is obvious to everyone and so most people just use that. The pressure of reducing every single penny out of the cost or semiconductors is enormous.

Everyone has a workflow and wants the input data cleansed how they like. Science journals are just the worst. So much time and money wasted by researchers just doing things like adding a hundred words to this paragraph for this submission, limiting the references to 30 for that one, putting the images all on one document for this journal, putting them in separate files for that one, making the figures independent, making all subfigures together on one page, using this dpi, using that margin with, page numbers yes, page numbers no. Editors should just ask for submissions to be in plain text, images just uploaded in whatever quality you have them, and then they could have a simple bash script do all their inane formatting and automatically fit sub figures evenly to a page. They'd probably complain this maybe 25 line script I'm imagining would put them out of work, though, so I'm not holding my breath.
It's easy enough to delete your comment if you see older ones after you've replied. With the amount of discussion around distributed system design on here, it's pretty egregious that we can't get the simplest transactional behavior right.

More likely, instead of dual purposing the satellites they'll end up finding a customer who is willing to pay for them to send up additional satellites that offer imagery, radio telemetry, or other sensor data. They'll get mixed in with the rest of the fleet, possibly acting as relays between satellites rather than downlink/uplinks themselves. Removing the downlink/uplink components would free up quite a bit of mass that could be dedicated to various sensor platforms, and the comms left would be the inter-satellite system already being used by the fleet.

There are lots of potential customers for this (especially if used for terrestrial imagery or similar sensing), and piggybacking on their existing telecom fleet to handle the uplink/downlink side could be a phenomenal bit of cost savings for them. And they get the benefit of improving the inter-satellite network with the additional relays.

Yes, consulting for enterprises doing desktop stuff for laboratory and factory automation is still a thing, specially in air gaped environments.

Qt is the major alternative for these customers.

If I were a dictator I would just put a deadline on it. January 1 2027: IPv4 forwarding is turned off on all core routers.

You can still use IPv4 internally if you have legacy devices, but anything on the Internet has to use IPv6. You have about 5 years to get it done. There are lots of solutions for specific use cases including stuff like ::ffff:1.2.3.4 and IPv4/IPv6 NAT devices. Most of which won't be as necessary as people think because IPv6 support is already widespread everywhere except ISPs.
Globals and locals are different. All compilers will give a global a specific memory location and load and store from it. Locals by contrast can be escape analyzed.
If that's your whole reasoning I think "of course!" is an overstatement.
One of the main advantages of TD-NIRS is that the signal it's imaging is "electrical".

Modalities like PET, BOLD fMRI, and CW-NIRS do depend upon saturation changes. For BOLD and CW-NIRS, it's the change in blood oxygen saturation.

TD-NIRS images the fast optical signal that is correlated with electrical activity in the cortex. MEG images the magnetic fields correlated with electrical activity in the cortex. IMO, they're pretty similar.
Fantastic stuff!

There are plenty of modern flashcarts around for various systems, but most of them are designed to let you load up a bunch of (often pirated) games onto an SD card and play them, and they're not very good for development. Nobody wants to build their ROM image, copy it to an SD card, swap SD cards around, and then reboot the system. (Plenty of people do that, it just sucks.)

It goes to show that making your own cartridge for development is not as hard as you might expect.

There are some high-end cartridges out there that let you do everything, with both SD cards and USB ports, but it's less common to see pure development cartridges, which could be made much more cheaply.
I assumed from reading the excerpt in the github issue that each emoji represented an actor or asynchronous action to make it obvious which parts of the story corresponded to technical concepts, but the documentation wasn't 100% consistent on this. When it got to discussing parallelizing actions, it was easy to represent multiple bank tellers with emoji. I can see how it would be very off-putting, though.
Ah yes for RAW work Darktable is my go-to software, it works great.
> It’s a classical chicken and egg situation. No services require IPv6, so there is no demand for IPv6 and thus no IPv6 offerings either.

Bugs based on optimizations that compilers make based on assumptions enabled by undefined behavior (like the null check issue from 2009 in the Linux kernel) actually don't cost very much. They get a disproportionate amount of scrutiny relative to their importance.
Yeah, good thermal design is a priority for us, since without it long compute sessions won't be comfortable.

- Most of the components in the front of our headset are low-power.

- Our detachable compute unit is in the back of the headset, with airflow going away from your head, so heat there shouldn't be too noticeable. (Contrast with the Quest, which, e.g. has everything in the front of the headset).

- We are looking into active cooling for the front part of our headset regardless, in order to sustain long sessions and prevent facial sweat due to low circulation.
9 percent? Doesn't sound like "crash".
If we are concerned with leakage of user data available in your own web program, then unsafe WASM code is more secure than unsafe code in a hypervisor because it prevents RCE, which results in full control of the hypervisor environment, which also enables transient attacks against the host environment, if there are vulnerabilities in your hypervisor (previously hypervisors had to be patched for Spectre). If we are talking about host platform protection against arbitrary malicious code, information leakage from neighboring processes/tabs, WASM is no different from a process boundary, at least in chrome, because that's how it's implemented. It's an implementation detail independent of WASM. Could as well be implemented with hardware virtualization, but it would make interfacing with browser APIs more expensive, probably to the point of impracticality.
It is interesting that there are many ham apps that are single person developed and closed source, but free to download. It's weird how open source is not ubiquitous in that hobby. This leaves lots off ageing, quirky software out there.
It’s a legitimate fear as a wet sleeping bag could kill you in the snow, but I’ve ever seen an actual Nalgene bottle fail even when we tried driving a forklift and a bobcat over one. I did crack one with liquid nitrogen but I don’t camp at those temperatures :-).

I’ve been given bottles made from other plastics but I’ve always been dubious about them.

I have cracked the lids, but that takes a lot of work and an aged lid. The lids are made of a different, softer material which is more compliant to make a good seal. I do replace the lids every few years.

Speaking of getting your gear soaked (not): a good habit in the snow is to put a nalgene of water upside down into the leg of each boot overnight to keep them from freezing. I guess you’d be concerned about that too.
Incidentally, even to a human observer they are very far from random (though they aren't entirely regular either).

OT question: Is it possible to use a wedge-shaped slit (uneven width) to increase the dynamic range of a slit-grating-camera phone spectrograph?

Backstory: I've repeatedly encountered deep confusion about color, even among first-tier physical-sciences graduate students. Yet color is widely taught K-2. Apparently without great success. So what might a rewrite, a modern learning progression for color, look like? Perhaps one based on spectra, a modern colorspace, and building on current understanding of color perception? Tablets are used in K - "find and take a picture of a circle". So how about using them for color? There's middle-school work with color "arithmetic" (an <R, G, B> binary triple with addition(light) and subtraction(filter)). And phone spectrographs are a thing. Thermal IR inspection cameras suggest having a context image aids understandability, and phones now have multiple cameras, so might one do a more accessible sample-with-context spectroscope app? With the light path folded flat, not sticking out? And a high dynamic range to permit sampling objects under ambient illumination? Might one craft a spectra-based introduction to color? For K?
It doesn't seem like that's possible right now: https://community.frame.work/t/investing-in-framework/3980/1...
It’s a matter of age, it’ll get better.

I used to go to the airport on wrong days. i used to forget things when grocery shopping even though I had a list in my hands. I can’t seem to remember how many kids my sister has (she has two). And at the same time I can recall a lot of useless crap like the code for the lockbox of an airbnb I have been to in 2015.

Just realizing you’re like this is half the work. Then you’ll just start double checking everything, and when that’s not enough (cause it won’t), then you’ll triple check.

It’s ok, I like to think that it’s a side effect of being a creative person :-)
Nope. Not a caffeine addict. My wife once challenged me to go without caffeine for 30 days. No problem. Not even a headache.
> I would gladly take a compiler that could not allocate local variables in registers

That sounds rather extreme. I imagine it would be ruinous to performance. To my knowledge the various safe alternatives to C have no trouble with register allocation. Safe Rust and Ada SPARK, for instance, or even Java.

> The standard does not preclude storing a raw pointer and a length together. Why couldn't the compiler do something like that and do a bounds check?

That technique is called fat pointers. It's been well researched. Walter Bright, who just posted a comment elsewhere in this thread, has a blog post on it. [0] I imagine ABI incompatibility is one of the main reasons it hasn't caught on.

C++ compilers do something similar, storing array lengths in an address like myArray[-1]. They need to store array lengths at runtime because of the delete[] operator (unless they can optimise it away of course). C++ still allows all sorts of pointer arithmetic though, so it wouldn't be easy for a compiler to offer Java-like guarantees against out-of-bounds access. Doing so takes a sophisticated tool like Valgrind rather than just another flag to gcc.
