this post is a fake argument with no one? the typical internet outrage pattern of using overly dramatized language like "dirty secret" to describe something thats... common knowledge? not a secret at all? openly talked about at any and every relevant industries conferences and trade shows?
everybody who isn't just reading clickbait and comments sections is well aware that the wh/kg for li-ion will never cross the atlantic much less the pacific, via air or sea. thats why the aviation industry went in on SAF/eFuels, thats why the shipping industry is playing with hydrogen and ammonia. everybody knows the litany of challenges there (please spare us yet another internet commenters thoughts on hydrogen), but the very fact that they're trying is in and of itself a clear admission of the understanding that li-ion doesn't get you there.
I think we'll see the global rich (western middle class) continue to fly well past the onset of the famines and refugee waves.
Without a single family detached house and a regular vacation flight most "middle class" people would have no idea why to get up in the morning. Our whole culture is built around lauding and striving toward that pattern as the good life. It will have to be taken from them, they will not give it up willingly.
They may not have been alluding to violence; perhaps something like democracy itself would be enough to take that lifestyle away from the middle class. If billionaires consolidate enough power & resources and push the tax burden onto the middle class which makes yearly vacations unaffordable
Apparently Tesla got caught cooking their books to the tune of 1.4B [1], so the numbers reported on the earnings call might not be as precise as one would expect.
does anyone know if any of the robot arms being used in these videos, especially the ones that look like just an aluminium extrusion, are off-the-shelf things that can be purchased somewhere? even if its a kit?
I would love to experiment with something like this but everytime I try to figure out what hardware to do it with there's a thousand cheap no-name options and then bam 30k+ for the pro ones.
I use Wipr in Safari on both, iOS and Mac. Small one time purchase each. And i enable only passive filters, not the active one, that requires page access.
Maybe but it doesn't affect the ad-blocking abilities of Firefox and uBlock Origin. It is a legal document, not a technical document.
If you want to go with ethics and trust, I am not particular fond of Brave practice of replacing ads for some shady cryptocurrency (BAT). You don't have to do that, you can just use it as an adblocking browser, but if you don't care about these things, the news of Firefox updating some privacy policy shouldn't affect you too much either.
Anyways, both Firefox and Brave/Chromium are open source, you can see what data is being sent out, and there are forks.
And to make things clear, I am not really a fan of Mozilla direction, I just switched because Firefox became better and Chrome worse in the last years.
The point of switching to Firefox is not "Google bad, Mozilla good". The point is to chip away at the chromium browser monopoly. If you have another non-chromium browser to recommend, please share as an alternative.
Mozilla has not proven themselves to be trustworthy, but I think most would still consider them to be less untrustworthy than Google. Firefox offers similar levels of support, feature parity, and performance to Chrome, which makes it an easy alternative to recommend. There are certainly other non-chromium options worth considering, but Firefox is still by far the most accessible.
No PWA support out of the box last time I looked. And Firefox (understandably but annoyingly) doesn't support some of the non-standardised Chrome APIs such as the File System Access API.
If someone was previously using Chrome, though, they're probably not that protective off their data. So it would seem like Firefox is a decent solution even if it is selling your data. Google was probably selling your data too...
I think this is going to be one of several blog posts they are writing essentially providing users with escape hatch ways to deal with features they've dropped. It wasn't just their edge DB play, but also the multi-tenant "schema only" db system they dropped recently. Both can be done on your own, with setup, and I think they're doing their best to show that to users through these kind of posts.
What's sort of hidden from this is that I believe they charge more for embedded syncs, so they have an incentive for you to use them vs. their edge system (which was on them to maintain globally). Embedded syncs are nice, because for every 5th "response time" benchmark we see from their competitors in the hosted Postgres world, Turso can basically say "0" to.
I'm honestly more surprised they dropped the multi-tenant stuff. That seems like a real use case for in the field devices. I'm guessing they likely have better ways to handle it in their rewrite, and don't want to maintain the current version till they release all the new stuff.
this is ~2 year old info from a presentation I can't dig up quick, but iirc the numbers were roughly $4 - 5 per kg of green hydrogen from western PEM systems, and about $1 even for grey hydrogen (steam reformed nat gas).
at the time rumor had it that the chinese alkaline systems were producing green hydrogen for $2 - 3/kg
the inflation reduction act put some monster subsidies in place that added up to something like $3 or $4 per kg, so effectively they were trying to force the economies of scale by moving the price drops forward several iterations.
of course the new administration is already ripping apart that legislation, so its doubtful much of that will pan out now (if you ever thought it would).
in the meantime, the price of a kwh of wind/solar has continued to decline rapidly, so the original $4-5 estimates can be reasonably eyeballed down to $3 - $4 now. still not enough, but in a decade it might be.
of course as with all of climate change economic math, so long as pollution is free its difficult to cost compete with.
I'd be interested to know what massive infusions during zIrp you're talking about, I'm not familiar with any (r&d stuff sure).
the IRA would have been a massive infusion, but it passed in '22, after the rate hikes (its how/why it got its dumb name). Even still most of its effects were convoluted tax credits that are difficult to model investment risk on right now (putting it nicely).
I don't know why it only just now occurred to me to wonder how you measure the KG of something lighter (less dense) than air.
I know mass is not the same measurement as weight, but we still mostly use weight to measure mass, don't we?
Obviously this has already been solved for helium, but is it just measuring volume and converting? Or pressure level in a known volume? Or I guess if you pressurize it enough it'll be more dense than air.
I am soooo grateful for this post. After years and years of words and one-off measurements, this is the first time I have seen clear measuring of the key metrics, specifically for someone considering the 'fast twitch shooter' (counterstrike et al) use case. To sum:
- the satellite handoff period is 15 seconds
- you cycle through the three nearest satellites
- on the farthest one, inside the 15 second stable connection window, latency is 40 - 55ms
- on the middle one latency is 30 - 45ms
- on the closest one latency is 20 - 35ms
- the moment of handoff between satellites is a 70 - 100ms latency spike
- more importantly it is a near guaranteed moment of ~10% packet loss
so my takeaway here is "it will mostly seem fine but you will stutter-lag every 15 seconds". given that not every 15 seconds will be an active moment of 'twitch off' shooting the engine will probably smooth over most of them without you noticing.
this could probably be used in subtle ways the same as laghacking already is. like if you knew some packet loss was coming and you knew how your engine handled it you could do things like time jumps around corners so you appear to teleport. or if the engine is very conservative then you could at least know "don't push that corner right now, wait 2 seconds for the handoff, then go".
edit: side note, thinking about the zoom use case, and this would be kindof awful? imagine dropping a syllable every 15 seconds in a conversation.
This is not how it works in practise. I’ve been on Starlink for more than three months, and I play CS and other competetive shooters daily. There is no such a thing 100ms latency spikes every X seconds. Same for packet loss. Teams calls are no problem at all, and the latency and quality of the Internet is comparible to that of a fibre lane. You wouldn’t be able to tell the difference if you didn’t know you are on the Starlink network.
Based on what? The receiver knows where it is since it has GPS. Starlink knows the orbits of their own satellites. Why wouldn't they queue up connections to upcoming satellites and then hand off from one to the next in anticipation of the one you are on eventually rotating out?
What's up with the apparent assumption they only track one satellite at a time or until there is a communication problem? That would be stupid (and why they obviously don't do that).
