google "DIY powerwall" if you're up for a bit of a technical challenge.

4 x 12V 200Ah isn't big enough for most houses, unless it's like a cabin in the woods somewhere. and you're right that the cycle life of those and cost is high.

but commercial li-ion based solutions are also expensive. However, if you can keep them at 80-85% state of charge, and rarely if ever discharge them below 30%, they should have lifespans 5-6x longer than the lead acid solution.

in either solution you can't really consider the full volts * Ah capacity of the battery to be usable. If you were to ever use all of the watt-hours in a 12V 200Ah battery you'd kill it, you never want to go below 20% state of charge... so to be conservative the actual capacity of a single battery is something like:

12 * 200 = 2400 Wh, then (2400 * 0.70) = 1680Wh.
Thanks! So I'm guessing the issue might be that Android mandates 4kb page sizes whilst the A10 CPU has a minimum of 16kb. Whilst Ubuntu and other standard distros don't care?
>Considering their current market cap, it surprises me that Tesla or Space X didn’t pick up BD.

Perhaps companies are leery of accepting Tesla's inflated shares as currency in any deal. SpaceX is still continuously raising cash, so I doubt they have a billion dollars to spend willy-nilly.
Thank you, I figured there was a blog or comment somewhere with more info.
> How we felt about what Trump said has become just as important as what Trump actually said.

This free interpretation of words uses a new (repurposed) trendy term too: "dog whistle". Suddenly you are free to interpret anything one says in the most negative light, just by claiming it's a "dogwhistling" for some group or action you despise.

I think people believe Linux is community driven project, while in reality it is strongly corporate backed. Just look at kernel contributions [1]. I think same applies to most of the infrastructure, someone works on FreeType, Cairo, Pango, etc.

In such case disjoint between users and developers is even further. I am professional developer, yet I have zero contributions to my framework and just a few contributions to libraries. After 10 years my contributions to Linux community limited to bug reports, few patches and manuals.

In reality there is not enough community support to maintain existing systems. "Freedom to take a project in another direction if they desired" by individual is overrated, that's TempleOS.

EDITED: Some bragging about making a difference

There are a lot of projects with less corporate influence. No systemd on BSD, but hardware support is not as good. Generic distributions is something that works for most of the users. There are a lot of niche distributions and projects (Void Linux runit!). Current state is just a reflection of users priorities.

>I dispute this assessment, it’s a drastic simplification and the comparison only starts in 1994, which is after a heavy swing in America to the right throughout the 80s and 90s. If anything, what the article shows is a regression to the long-term political mean, not a move left.

It shows the political swing over 25+ years capturing clinton, bush, and obama presidencies. We see that during bush and clinton the democrats were quite stable. Only at around 2011 did the graph start seeing a shift where 2017 has the democrats having moved far left on average.

This data is available from other sources. The other reality is that I can personally see it. The democrats used to have a strong moderate base, they are gone.

There are many many people writing on how the political divide is so bad that it feels like never before.

The reality is that Obama(first black president) was doomed to identity politics. Which has created this much division.

>A great example I happen to have favorited on YouTube, check out the healthcare debate in 1971 [0]. It’s essentially Medicare for all (D) vs practically Obamacare (but from an R).

Not available in my country. 1971 is much to old to properly compare to today's political climate.
It's totally reasonable to be sad about this. It pattern matches to a loss of free speech, and when society sees free speech being violated, it should evoke strong emotions (hopefully even more severe than sadness).

This is not, however, a violation of free speech, even if you believe in the general concept that a private company should allow dissenting opinions on its platform. This user has violated the "yelling fire in a crowded theatre" exception to free speech, which even the most ardent supporters of the concept admit is important to protect.

These private institutions aren't perfect, and judging if speech breaks the one exception to the moral concept of "free speech" is hard. We'll get it wrong. The alternative, however, is to let the panic incited to occur unabated, which seems substantially worse.
I think one big unspoken assumption in a lot of this discussion is that claims to something like the Dems actually rigging and stealing the election would reasonably lead to physical resistance. For instance, if the Dems actually were stealing the election, many people would probably sympathize with the rioters. The assumption is that this isn't true, but it's something that does warrant physical resistance, therefore claims to it at a certain level are the same as incitement to violence. There's also the implicit assumption that the president needs to exercise special care because of his power.

Like a lot of these sorts of things, the issues are complex, and I think a lot could come to light in coming days that might change perspective on exactly what Trump did and didn't do. But I think some care is needed in being explicit about what's being claimed. I think political biases are bleeding into claims of violence-inciting speech more than people realize. I personally don't think claiming election fraud is impeachable, even if it is followed by events such as happened at the capitol, but I do think, say, coercion of a public official might be, as would willfully neglecting to institute expected security protocols at an event known to be high risk.

* defunding schools in minority areas via how school funding is created
* war on drugs and mandatory minimum sentencing
* selling military grade equipment to local police forces
* supporting private prison infrastructure
* preventing open discussion of criminal justice reform despite having the largest prison population in the developed world
* sending drugs into minority communities via the CIA
* supporting police unequivocally despite evidence of wrongdoing going unpunished

... are all public policies and social policies that can lead to that outcome.

It’s not like cities “control their police departments”. Police are all autonomous with their own cultures and political beliefs influenced by a lot of rhetoric and policy and experience.

I'm at a technology research company that is primarily using C++ as the main company tool. The development team is small, and the code is the result of 22 years of constant revision by PhDs. One of our Never To Be Violated Rules, simply because the number of hidden landmines is far to numerous, is template programming. When generic programming is required we use a web language like PHP where the type of something is contextual and one can be free and loose and sloppy if they want. Between the two extremes of our formal as fuck C++ base and the anything goes generic web languages we maintain surprisingly high levels of productivity, with very low bug counts. Having a tiny team helps, as we all know the code based inside out.

Wtf? Nobody said anything of the sort, and if they did they would have been downvoted to the maximum. This is just totally absurd revisionist, we were only five years removed from the W Bush administration, which committed legitimate war crimes and left office with a 22% approval rating.
I have no idea about what twilio did, as this is all completely unrelated to any work I've ever done, so that leads me to wonder about contingencies like this in general.

From the perspective of any company using a service like twilio (i.e., not just Parler and this specific set of events), would there not be some sort of failsafe in case something just like this were to happen? Or would this kind of thing be so nearly inconceivable that you wouldn't protect against it?

The high efficiency panels are typically semi-flexible without the frame, are they not? Do you think it would be possible to obtain and mount them without a rigid frame? Or even to remove them from the frame? I'm asking partly because I had considered making some sort of basic, folding, portable solar panel structure- imagine a few semi-flexible panels duct-taped together. (I'd likely not _actually_ use duct tape).
I guess you forgot about North Korea? Or Iran? Russia? China? Trump only had 4 years in office, these others are dictators for life and have far more influence to spread evil throughout the world.

The "coup" was a joke by any standard, the only reason it became such a big deal is because DC cops allowed the rioters into the Capitol instead of doing their job. I for one would've liked to see tear gas and rubber bullets but those were worryingly absent.

They get paid so little because there isn't any other legal means to exchange a bug into money. A monopoly on the only legal way to sell goods means that you get bad prices.

But I do wonder if it would be possible to set up a legal alternative. I suspect if you did you would find law makers lobbied to make it illegal and it would already be decided as unethical by the corporate designed ethics systems.
This company looks to be a team of three (probably very smart) engineers who build cool custom software for likely relatively small clients. The software is likely only supported and modified by them. In that scenario something like Haskell makes sense - however once you need to scale your engineering footprint beyond 5-10 people it becomes virtually impossible to rationalize using a niche language like Haskell.

You are downvoted, but I think you are correct on the Russian story. It was made up or at least severely exaggerated to save face in an embarrassing election defeat. I cannot understand how people can still believe this.

Considering the founder of Telegram more or less had his previous startup VK (Russian competitor to Facebook) stolen by Putin after his refusal to hand over info about Ukrainian protestors [1], and has left the country with no interest in returning, I'd be inclined to trust that Telegram is not a front for the Russian state, quite the contrary in fact.

> In his article, Vitalik claims Electrum’s cosigner model isn’t good enough, without mentioning it by name.

He says multisig has been very successful for organizations like the Ethereum Foundation, but suggests that it's possible to better for individuals. You are free to choose something that reduces to N-of-M, if you want to trust financial institutions, family/friends, and/or (mostly) yourself.

If I'm understanding what he writes correctly, it's somewhat similar to a "1 OR 4-of-7" multisig concept. Fairly sure this is supported by the Bitcoin protocol, although I don't think any wallets support it. There might be additional options you can implement on Ethereum that might be harder (read: require protocol upgrades) on Bitcoin. Time delays, maximum spend amounts (with exceptions), etc.

Also, I'm not sure why you're calling it the "Electrum cosigner" model. I thought multisig was a feature of the Bitcoin protocol, and not of the Electrum client?

Apples old hardware isn't all that closed - most models have enough exploits it's very possible to get your own low level code running.

The key issue is that hardware drivers aren't there, and that requires a massive amount of reverse engineering work.

Apple could release documentation for the hardware, making things easier, but from apples point of view that opens them up to patent litigation (you can be sure trolls will scour the documentation for evidence of violated patents), and most internal documentation isn't of sufficient quality to release without at least someone reading it all over and removing swearwords...

Collecting the documentation together will be hard - it is probably scattered amongst hundreds of git repos, wikis, documents, spreadsheets, photos of whiteboards, on some engineers laptop, and mixed in with code and secrets.

Even then, without a lot of people putting a lot of effort in, you wouldn't see desktop linux running...

Overall, I can see why Apple doesn't help these guys - the disadvantages outweigh the advantages.

I wonder how an autonomous truck responds when a tire blows
Yeah I've got a hefty PC here too running Windows. WSL2 is wonderful until you get your first Hyper-V bugcheck, filesystem corruption or weird ass network issue to debug. It's really not very good. I used it from day one and WSL1 before that which was even more horrible (NT impedance mismatch was obvious)

The compromise for me before migrating to Mac was using Windows on the desktop with Ubuntu VMs in Virtualbox. I had whole clusters running on my desktop.

Windows 10 is fairly decent on most hardware I have found. If they finished off all the little quality issues, had a decently integrated mobile ecosystem and stopped all the telemetry bullshit I'd be there now. I had some hope back in 2015ish when I was full time windows desktop dev with WP handset etc. Alas the world moved on so I dug the old Unix hat out.

From the 'National Honey Board' website (USA)
https://honey.com/newsroom/presskit/honey-industry-facts

Many commercial beekeepers migrate their colonies during the year to provide pollination services to farmers and to reach the most abundant sources of nectar.

Millions of acres of U.S. fruit, vegetable, oilseed and legume seed crops depend on insect pollination, including honey bees.

The USDA has estimated that 80 percent of insect crop pollination is accomplished by honey bees. Approximately one-third of the total human diet is derived directly or indirectly from insect-pollinated plants (fruits, legumes and vegetables).

Crop Dependence

The almond crop is entirely dependent on honey bee pollination. Without honey bees, there would be no almonds. More than 80 percent of the world's almonds are produced in California.3 To pollinate California's approximately 790,000 bearing acres of almonds4 requires more than a million colonies of honey bees.

Numerous other crops are 90 percent dependent on honey bee pollination. Some of those crops include apples, avocados, blueberries, cherries, cranberries and sunflowers. Other crops such as cucumbers, kiwi fruit, melons and vegetables are also pollinated by honey bees.*
"This year"... kinda... This year there will be the first real tests run with no one in the cab. "By 2024,TuSimple plans to achieve Level 4 autonomy, meaning that its trucks will be able to operate without a human driver under limited conditions that may include time of day, weather, or premapped routes."

Somehow I've managed to miss that trucks are better for this stuff not just because of the type of driving they do, but also because they're trucks! Being bigger gives them some advantages.

"Trucks are also a better platform for autonomy, with their large size providing more power for computers and an improved field of view for sensors, which can be mounted higher off the ground."
