@wavedrom hey, I remember that PCB! :)

3D printed from brass / copper. Good performance @drom/helical-filter" target="_blank" rel="nofollow noopener">observablehq.com/@drom/helical-… Design is parametrizable in 500-2000MHz range. Did 2 and 3 stage versions

@AnneYBrintonPhD no, but I have the reMarkable tablet and I'm very happy with it. For several years I've used it daily for reading and note taking. It also has a presentation mode which I use for meetings. $279.

Rates are getting high enough that soon it will be economical to build a second electrical grid using modern HVDC underground distribution.

@cosmicfibretion I think our search for Hₒ is meaningless until we know the gravitational force of the wave function. Cold low-density interstellar gas is likely highly entangled. Is gravity proportional to the mass of the entangled states, or to its classical information? 🤷🏻‍♂️

And the plot thickens! data.desi.lbl.gov/public/papers/…

@Morgan628 @sdamico exactly. The satellite cost is nearly irrelevant because it gets divided by the subscriber count.

@sdamico The consumer dish cost was cited by Shotwell as the top technical obatacle to commercial viability of Starlink. Closing the launch and satellite side made sense but making mass produced state of the art phased array antennas cheap enough was the problem.

The *domestic consumer electronics operation* that is the starlink “dish” + router assembly is even more underrated and is extremely legit.

@pmddomingos And for todays lesson... How to scale the y axis.

Average temperatures by month instead of year, and suddenly the climate crisis looks like a joke.

@Molson_Hart What are your incentives for making this video? Is this a video the CCP would like to encourage? What are your opinions on their human rights violations and abolishment of civil liberties? Any opinion on whether Taiwan is a part of China?

@Andercot Solar should easily last 25 to 50 years. You're showing a black swan event. Solar is also a fraction the cost of nuclear, even if you combine it with batteries. Lastly, you're not counting the Uranium mining land use which is super toxic.

What's better for the environment: - 1,000 acres of solar panels that produce on average 150 MW and lasts <10 years - 25 acres for an AP1000 that outputs 1,000 MW and lasts >50 years?

@cosmicfibretion A very small number of people can appreciate the profoundness of this premise.

If it is the Hilbert space of states that is fundamental, and if this space is traversable, interstellar travel would never be necessary for the long-term survival of a species.

@bindureddy The judgment was proportional to interest payments he would've paid had he not fraudulently reported the asset values. The NY law (+similar laws in other states) are used frequently. Civil fraud laws enable an environment conducive to business and is why our country is so great.

Democracy Is Dying In The US Trump has to pay half a billion in fines for over valuing his properties!!! Why is that a crime? The banks have their own way of valuing these properties and got their loans paid back! The US is behaving like a 3rd world nation by punishing the opposition! Weaponizing the legal system to stifle the democratic process is just one more way democracy is dying slowly in this country 😭😭

@sdamico Most people don't get that nearly all gov't is run by these weird small businesses without websites or public filings.

It’s going to blow people’s minds when we let the government efficiently execute on stuff again versus the post-1970s privatization via nonprofits we’ve been accustomed to as “big government”

I'm so proud to be featured on my friend Jeff Ward's amazing podcast about the early SpaceX years. If you want to know about my life or experiences checkout this 28 minute conversation. I'm so happy to have my experience memorialized so well. itsnotrocketsciencepodcast.com/post/ep-5-joel…

The maddening thing about living with a sword-of-Damocles type situation like the Chinese invasion threat in Taiwan is, there’s no clean resolution in sight. There’s a thousand and one reasons why it doesn’t make sense for Xi to invade, but the fact of the matter is, he can. And quite honestly if he does, at this point we can’t say we haven’t been warned. But life has to go on in the “probablies.” We’ll probably be fine, because Xi probably won’t invade, and if he does the United States would probably come promptly to our aid. I can’t help but feel like my faith in that last “probably” has been seriously shaken in the last six month. There are clear signs that America is turning inwards, and looks to be leaving Ukraine in a grim lurch. There are always those in Taiwan who doubted the United States would actually come to the aid of Taiwan (see President Ma’s interview with DW for a prime example). While I still believe that they are wrong and that Taiwan is a core US foreign policy concern, nothing seems certain anymore, especially if Trump is the next president. And the truth it it has always been the way of the world’s largest superpower to vacillate between idealistic overextension and stubborn, narrow, America-first realism. Tomorrow, Taiwan goes to the polls and I’d like to take a moment just to celebrate that. Tomorrow, as it has been every four years ever since 1996 since the first direct presidential election took place, the people of Taiwan will choose their own leader and have a say in their own destiny. I’d even celebrate each of the three candidates: during the run up to the election inevitably harsh words were said but each candidate is an exceptional individual who accomplished extraordinary things to get them to this place in their careers. And whoever is elected president tomorrow, I hope the people of Taiwan will rally behind him because the hard work of defending Taiwan will never stop. Each new day is a day we have to make Xi Jinping think “not today.” politico.com/news/magazine/…

@vkhosla Only if we have rank choice voting. Otherwise, a 3rd party will lead to even more extreme outcomes.

Maybe time for an independents party?

Coming Q4 @ImpulseLabs_

@eshear what if gravity is just the local simulator slowing down?

The reason why your memories of the distant past are so fuzzy is the same reason the buildings in the distance in a video game are low polygon count and shrouded in fog — the simulators need to conserve resources to render the nearby stuff.

@sdamico I'm very excited about this. Especially for PCB design, architectural design, and process engineering. Most startups fail due to missing engineering milestones. AI could change that.

This is ~1 year away from being usable by hobbyists, max

@whitequark Another pipe dream is to see some of the proprietary toolchains (Efinix, lattice, etc) running in a WebAssembly emulator. It may be a bit slow, but it beats setting up the tools yourself.

@whitequark wow, congrats! This is something I've dreamed of doing for a long time. This could dramatically reduce developer time. I hope all hardware development moves to the browser soon.

I finally did it!!! a complete FPGA toolchain (synthesis, placement, routing, and programming) running entirely in the browser
