Nobody is safe from a nation-state "attack" they'll just go threaten your providers to give up your data. Passwords written on paper are probably safer than a centralized password manager for almost every circumstance other than a government coming after you.
I recognize the "esp32 perched on top of a circuit board" from the picture. I've got a couple of those at my house right now, I'm on the second version of one board and the third of another. I think I'm going down a very similar road for a different product. Would you be willing to some paid advising? I'm an EE so I don't need hand-holding on the actual boards or programming, really just looking for more information on everything else around the edges. Either way, thanks for the article. It was nice to get some validation of my development process.
Maybe you didn't read that it was the history of how Britain eradicated rabies?
For most of history until the rabies vaccine if you got bit by a dog there was a 5% chance it killed you unless you amputated the affected limb.
These are very high stakes for a dog bite.
1. They do a really bad job because you can't get fired
2. My package is delivered late yet again
3. I don't bother calling because the other 8 times I did I wasted an hour, nobody did anything (because nobody can get fired) and I didn't get any money back
4. Look how great we're doing! Complaints are down
5. Give us more funding because we're doing such a good job
This is just as likely of a spiral if we keep it publicly owned. It's also not good. How do you get good outcomes with.no accountability?
My problem rate with Fedex or UPS is maybe 0.1% of packages. I can't remember the last time I had a delivery issue.
Just this week I had a package that was supposed to be delivered by Monday that lost tracking and didn't show up until Wednesday.
It might be "basically fine and good enough" but it's definitely not "amazing and completely beyond reproach" at least in my opinion.
Prior to COVID I seem to remember that the point of a vaccine was so that you didn't get the disease at all. That's where the herd immunity argument comes from. If 85-90% of the herd has immunity (immunity meaning you can't catch it at all) then even the people who can't get the vaccine are protected because the susceptible are too spread out for the infection to spread.
Do you see how this absolutely requires not just a lowered infection rate with lowered severity of infection? You need a less than ~10% chance of infection in the vaccinated/otherwise immune for the math to work. If the chances of infection after vaccination are still 80% then there is still a large reservoir of potential carriers and you don't have herd immunity.
For most of history what people expected out of a vaccine was immunity from infection not still getting infected but with less severity.
Huh that's interesting! I found celery to mostly match my expectations. I used it in a couple of django apps. My only real foot gun was around having to set an EAGER setting for local development or tasks never got executed.
How did you find your expectations and celery's actual semantics to be different? I'm trying to document well and it seems like I might have some implicit assumptions that I could make explicit, but I don't know what they are since they're already in my head and matching celery it seems.
This really seems like a solution in search of a problem. Maybe it would be useful for pro tour riders, but I would guess it'll be banned as not in the spirit of cycle racing. Recumbents would really change the game in the pro tour for speed but the UCI doesn't allow them for the same reason.
The idea that's been floating around in my head for the last few years is something like "it's being trained by the data produced by people, it's going to have many human flaws as a result"
I always thought it had to do with which way the vessel leaned while turning. Boats will lean into the turn, ships out. I guess that really only tells you if that's a displacement hull or planing hull, though.
And even that's not the hard part of a black start. The plant control is relatively easy. What's hard is grid coordination.
All generation and consumption have to be almost perfectly balanced every second of every day. And the power company doesn't have good addressability of load. Worse when you restore power to an area all their stuff turns on in parallel giving an inrush that could be 3x or more the steady state.
A black start is a very drawn out process of bringing generation and load online in a balanced way and with wait times between load increases for stabilization.
The energy density on super capacitors is pretty bad. If you imagine full power 200kW braking for 5 seconds that's 1 mega joule and at a best case 8 watt hours per liter you're going to need 35 liters minimum. Really you probably need to double that so you can float up and down and never fully saturate the capacitor as power inflow is going to drop as you get closer and closer to fully charged.
Closest I can think of is flywheel "battery" storage tech many of which do have magnetic bearings and also some way to get power in and out of the flywheel so basically a motor. It's not exactly what you're looking for but there's prior art out there.
Aren't deed restrictions usually done at the state level? If so, the city can't just magic them away. State law is going to trump city law unless the city's restrictions are tighter.
Please tell me how I can just strip deed restrictions simply because I don't like them and/or they're inconvenient for me.
Deed restrictions are the mechanism that basically all HOAs are built upon so if you can just skirt around them because $reasons there are millions of people who would like to know.
Looks pretty normal to me for ships of that era. Wooden masts and natural cordage means you need a lot of rigging to keep things standing.
Comparing these rigs to modern ones with aluminum masts and stainless wire or dyneema rope is very apples to oranges.
Even more so since 97% of modern boats have Bermudan rigs (triangle sails) where as these ships have square sails.
There was a time in the early steamship days where they carried both engines and sails. If that's what you object to it's very easy to verify this with historical records.
If something else, sure maybe.
Okay, well that's a start. Could you help me understand where I went wrong? I'm not trying to be stupid here but just saying "wrong" is extremely unhelpful.
If the data is going through the air or a wire it can be sniffed, right? Is every message signed or encrypted like ssl/tls, or is this just some kind of extra header(s)?
I think this kind of corruption has been going on for a long time. Look at this case and how a Supreme Court decision didn't really get respected despite it being pretty clear. However bad you think any one thing Trump has done is, this is almost certainly as bad for the feeling of the rule of law. https://en.wikipedia.org/wiki/Worcester_v._Georgia
Just to be clear I'm not trying to say what's happening is good or right. Just that it's not new. And I used something really old to try and "prove" it's not a recent phenomena and help people maybe see past the recency bias.
Are you new to the club? I saw these problems you're talking about with Biden, Trump1, Obama and Bush Jr. Of course I'm not old enough to really know about what Clinton or Bush Sr or Reagan or anyone before that did.
I know it's super annoying to have someone rain on your "but THIS stuff is REALLY bad!" parade, but that the rulers are corrupt isn't new. It's just new to a lot of people.
Yeah but there's a difference there. I can buy alcohol out of state and if I bring it back in, that's on me.
Does anyone think that Minnesotans who are out of MN at the time of their bet will be allowed to bet? I don't think they'll be allowed, but they should be.
Be careful, the market makers always win. If you go against them, you make yourself a target.
The tunnel will very likely be less disruptive to marine animals than ferry boats. During the construction yes it will be worse but 10 years after? The ecosystem will have forgotten the disruption and will have gained additional peace from reduced/eliminated ferries.
It has always amazed me how much trouble the SPA folks are willing to go to in order to slowly rebuild just normal boring URLs with querystrings because users demand deep linking and back buttons and the like.
Or you could accept that you're probably going to need a round trip to the server and use a normal URL and it's fine.
For all but the absolute biggest websites in the world, anyhow. At Facebook or Google scale yeah it's needed.
It's a closed loop on the geo side sure.
How do you cool the steam off enough to condense so it can go and be boiler feed water again?
Lots of power plants use cooling towers for this which are typically evaporative. Some are dry, sure, but most are wet.
Not to be rude, but that's definitionally NOT net metering. Net metering is where you only get changed for your net consumption. If they're looking at your gross consumption and gross production separately, it just can't be net metering. You might still decide to sell solar to the grid for the wholesale price and get a reduction in your bill, but it's not net metering.
Net metering is really, really smart when the installed base is small relative to the fossil fuel power plant capacity. But it doesn't scale forever. Once it gets up towards 20-40% of the fossil fuel capacity, it goes from an asset to a liability.
Suppose I have a 100MW gas turbine. And suppose there's 1MW of solar installed in my generation network. I don't really care if I sell 80MW at noon and 90MW around dinner time and 50MW through the night, or if instead it's 79MW at noon and 91MW at dinner and 51MW at night. The gas costs about the same irrespective of when I burn it so a bit of a fuel shift doesn't really matter.
But take that 1MW and turn it into 20MW and suddenly we go from 80MW at noon to 60MW at noon, 90MW at dinner to 110MW at dinner and uh oh. You see the problem? Whatever losses I endured at noon I don't get to make up for at dinner because my plant only goes up to 100MW and now we're not just shifting when we burn how much fuel, we're literally having to shift the power generation to a different plant.
Is this example precisely accurate? Absolutely not. But it helps you get a feel for the problem of net metering at scale. The grid can act as a battery for a few % of total generation, but by the time you hit some number, maybe 20% maybe 40% net metering turns from a cool math trick to a real cost on the grid.
Oooof that's rough.
One strategy to convince is to get someone less technical than you to sit by you while you try and trace everything from one error'd HTTP request from start to finish to diagnose the problem. If they see it takes half a day to check every call to every internal endpoint to 100% satisfy a particular request sometimes that can help.
Also sometimes they just think "this is a bunch of nerd stuff, why are you involving me?!" So it's not foolproof.
I once worked at a place with more micro services than engineers. We joked about "we have as many 8s of uptime as you need!"
