If so, what if they're malicious and don't want to do so as to not give up their collateral?

Auger[0] has something like this:

"Reputation (REP) and (REPv2) is a cryptocurrency, used by reporters during market dispute phases of Augur. REP and REPv2 holders must perform work, in the form of staking their REP or REPv2 on correct outcomes, to receive a portion of the markets settlement fees. If you do not report correctly, you do not get the fees. If you report incorrectly, you lose your REP or REPv2. If you don’t participate in a fork (when the network has a very large dispute over an outcome), you permanently lose your ability to migrate your REP or REPv2 to a forked universe, making it functionally useless within the used version of the Augur Protocol, and in theory making it worthless. Passive holders of Reputation (REP or REPv2) that are not using their Reputation (REP or REPv2) within the Augur protocol to stake on disputes and forks are penalized. The treatment of REP and REPv2 within the Augur protocol is governed not by the Forecast Foundation but by the protocols smart contracts as described in the Augur white paper and documentation."

Other protocols may handle things differently.

> All of this can be solved by the law (eventually escalating to people allowed to use deadly force), but at that point why do you even need a blockchain?

Assuming if the law in all jurisdictions around the world were as sufficient for all cases presently and into the future. Also this assumes that its not the enforcers of a particular law aren't also the ones that the on chain claimant wants to take action against (again, the payout would need to be high enough for those to incentivize action against a particular jurisdictions enforcers, which need not necessarily mean engaging on the property, but anything to get the enforcers to back off even going after friends and family and their property in retaliation [which is more doable in jurisdictions who databases with such sensitive information have been compromised])

If you’re willing to use a cast iron wok, Lodge makes one with a flat bottom on the outside but curved on the inside. You have to make some major technique concessions, but it will work on induction, and if you use a butane torch while flipping food you can almost get a wok hei going.

This has sort of been my experience with induction beyond woks too, it often requires technique and equipment concessions. Great for boiling water and sautéing though. The tops also have durability/longevity issues when compared to gas and that isn’t usually acknowledged.
However, if you have no government, the housechain could be a way for a decentralized society to implement the concept of a land registry. Once everyone agrees that the housechain is proof of ownership, then measures can be taken to enforce that without necessarily evoking a central government.

I'm not sold on the idea of a society without a central government, but I think the blockchain would help — or even enable — such an experiment.
Probably not. I only subscribed like 6 years ago. Definitely didn’t feel DRM free to me from that point.
Fascism and Communism aren't the same. Communism defines the people who should die based on class; Fascism does it based on nation.

Scientists Discover Gene That Increases Risk of Dying from Covid
Our satellite team in college used GNURadio to modulate and demodulate our radio signals, and to automate the entire pass (in conjunction with our mission operations team). I remember at that time (2016-2018), there was an absolute dearth of information on something as simple as demodulating GMSK, much less OQPSK. The given blocks for these modulation types never worked, so we had to build out custom blocks in C++ to have a chance at interacting with an actual spacecraft in flight (with all the goodies like active Doppler compensation etc)
HTGR has faced numerous development problems.

One of the coolest sounding ideas is the "pebble bed" reactor where you have carbide coated spheres that are fed into the top of the reactor and get withdrawn from the bottom, taken up an elevator and replaced.

When they tested this out in air the spheres we well lubricated and slipped past each other. In hot helium the Germans found that there was a lot more friction and the spheres were sticking to each other, cracking, getting stuck, and releasing radiation.

"Prismatic" designs where the same material is in blocks seem a little more promising. Still the reactors haven't done that well and as lurid the stories around the plutonium economy have been, the ratio of progress to problems for the liquid metal fast breeder reactor has been better.

We know how to bury oxide fuels for the long term and we know how to reprocess them. If there is a "what to do about the waste" problem it's that we can't make up our minds. Carbide fuels can be encapsulated in concrete and stored for the medium term but the actual mass and volume of the fuel is dramatically more than the LWR fuel because of the low power density. The long term stability for burial is not established, and the amount of material is 10x more. Reprocessing is not developed and faces the problems of dealing with a large amount of 'filler' that is going to be somewhat radioactive and have to be dealt with.
I think the idea is they can run extra-inefficiency to produce even more heat if needed.
I don't think it matters how they're obtained. What is the value/meaning of a loyalty point if it can't be substituted with a dollar point? Either they only come in to play when you have an offer for exactly the same dollar value (after transfer costs), as a tie breaker of sorts, or they are eventually going to be valued at some dollar amount. i.e. this new employer is offering an additional $10 (after transfer costs) but I'm more loyal to my current employer.
EMFs (such as from induction cooktops) absolutely have an impact on health. A study I cited in another comment indicates that a compliant induction cooktop emits 16x the amount on non-ionizing radiation that’s considered safe.
Cleaning alone is the best motivator for induction.

I mean who doesn't spill when cooking?
Good point. Remember after the fall of the Soviet Union all the Russians being shocked at how empty the shelves were in America?
Blockchains can, and most likely will, be federated. Legal agreements can be managed via such a system. Bear in mind that the blockchain does not solve politics, and all the problems you mention are a problem of the currently most common implementation of a blockchain, which is cryptocurrencies.
> Recommendation algorithms really need to come with extensive UIs for tweaking, tuning and cleanup (less like this, more like this, don't include this, you're seeing this because of... etc...), maybe completely new 'exploration UIs' to actively find new stuff at the edge and beyond my own bubble.

> IMHO recommendation algorithms could be really useful if they allowed the user to play a more active role. Give us a "power user UI".

I think you are fundamentally misunderstanding the optimization behind “the algorithm”.

They’re not optimizing for usefulness or, god forbid, life enhancing stuff. They’re optimizing for engagement. Sugar for our brains. If the user could control what they see in the platform we could self optimize for usefulness. This would go directly against their wishes.

1h week of life enhancing videos = 10$

10h week of clickbait or rage inducing videos = 100$

Yeap, user control, never gonna happen.

I confirm the effects of vitamin D3 with my own observations.

Vitamin D3 is an adaptogen for the immune system, it is an antioxidant in mitochondria, it plays so many different roles.

No wonder it has such a beneficial effect on MS and CFS/ME patients who suffer from autoimmunity and mitochondrial manifestations. Vitamin D3 alone is not the ultimate cure per se, but it is a part of a possible cure for sure.

Note of caution to those who supplement vitamin D3 for more than 2 months: always add vitamin K2 MK-7 to the mix to avoid the possible development of arterial calcification.
Some are just handed everything they need yet still fail. I started out in life with advantages, although didn't realise it at the time. Went through a series of dead end jobs, a failed business, a few failed relationships, ended up on the street.

My real luck came along when someone gave me a chance to get back on my feet and start afresh with the benefit of all that experience and the knowledge of what can happen. I realised that, previously, I was just unmotivated to do what was necessary to achieve anything in life, I was coasting along and not really trying.

I do OK now, I work hard and make sacrifices, don't waste money and invest all my spare income. Not exactly rocket science, I just wish I had started sooner.
> "You know what, I'm going to for sure support this one particular issue, and abstain on the rest."

A better strategy is to trade your vote away on anything that isn't your core issue. You trade with political opponents for their support when the issue you do care about comes up.

Using that technique, even a single representative can have quite some impact, as long as the issue they care about is narrow enough.

So, is there evidence, as in peer-reviewed studies, that PoS blockchains can handle the volume of transactions of traditional financial systems while requiring LESS energy?
I made it two weeks without drinking more than a half bottle of wine a night. Then I finished my project and now, yeah. Fuck it. And fuck the bbc and the guardian as well. They just contribute to the general feeling of everything you could possibly think of having already been controlled for. We're living in a desperate state, ladies and gentlemen. Almost all of our autonomy has been taken away. You can't travel to another country, or get back, and at times you can't leave the house. Wherever you go, you're surrounded by the same stew of idiocracy that's exploded from being an American backwoods hillbilly sociopathic mania into a generalized trend where everyone is constantly expecting the apocalypse, all the time, everywhere. And you can't escape the idiots because there is literally no other outlet except this ludicrous online world, largely run and managed by botnets, whose primary purpose is to keep you agitated and off-balance most of the day. For what reasons we might speculate but it would behoove no one to claim to know. Nonetheless, that's there. The ever-present, constant, unceasing, morning-to-night traumatization of you and me as individuals by this machine of fear and panic and rumor. Which even if we don't subscribe to, gets to us because our boomer parents subscribe to it and call us and tell us the latest insane ideas they've fallen victim to. And we're living as a really traumatized group of people now. I feel it and see it all around me. Literally everyone I know has PTSD as a result of this pandemic.

So thanks a lot, Guardian, for telling us how embracing my messy life is a form of self-improvement. Seriously, go fuck yourself.

Does anyone with knowledge about volcanoes have context on how big this is? Clearly not small, but is this a once-in-a-decade or a once-in-a-lifetime size explosion? Are there any well-known eruptions to compare it to (e.g. Mount St. Helens)?
We bought a professional "manual" (no fancy electronics) from a restaurant (with knobs and no touch), for 100$ each. And built our own system with that.

You can set the knob, and turn it on and off with a relee, connected to a raspberry pi. We have temperature sensors on the "food side" of the pans and pots, since what we care about is the temperature that the food feels.

99% of the time we don't use it with the pis, but have a couple of recipes as Jupyter notebooks that we use the temp control and temp staging with.

One advantage of induction over gas here, is that the thermal mass of some induction pots and pans is almost zero, and temperature changes are instantaneous, so from the point of view of control algorithms, programming induction cooking is infinitely better than any other system that i've used, cause you don't have to solve a PDE to regulate the temperature. YOu can just turn it on if its too cold and off if its too hot, and that's it. +-0.5C of accuracy, which at the 100$ level for a single plate is unbeatable.

We spent ~400$ for 3 heats. 100% recommend.
Most people don't live in a dense large city. It is telling you equate those people with living in a third world. Country though.

Gas blows induction out of the water for actual cooking, not just reheating stuff

So cash, wire/bank transfers, paypal have never been used for fraud?

I have news for you. Financial fraud existed even before the concept of what we know of modern money.

I would be confident to assert that pretty much all financial infrastructure and instruments have been used for fraud, historically.

Crypto does not have a monopoly on that and you know it.
For some reason, the second block of code has stopped working for me as keyfield-value no longer has any visible innerHTML and it returns undefined. The following is a less elegant, but equally effective, way of doing the same thing:

myString=''; myKeys=document.getElementsByClassName('keyfield-value'); for(ix=0; ix<myKeys.length; ix++){ myString = myString+ myKeys[ix].innerHTML)+"\n"; } console.log(myString)

> Nobody is advocating for integration tests to the exclusion of unit tests.

Oh, I got here just now, but well, let me advocate it. (Well, not all unit tests, but most of them.)

The ideal layer to test is the one that gives you visible behavior. You should test there, and compare the behavior with the specification.

Invisible behavior is almost never well defined and as a consequence any test there has a very high maintenance cost and low confidence results. Besides, it has a huge test area that comes with the large freedom of choice there. It is a bad thing to test in general.

Now, of course there are exceptions where the invisible behavior is well defined or where it has a lower test area than the visible one. On this case it's well worth testing there. But those are the exception.

You’re referencing the point of Bitcoin, not the point of crypto. Other platforms aren’t interested in destroying the existing financial system and would much rather digitize it and make it open to everyone.
No, that's just called learning how to socialize when you're semi-autistic. It's not and shouldn't be a rallying cry for people who can't/never get their shit together.

I wasn't around then, but I would be surprised if that description of TiVo's actions is accurate. I'm more inclined to believe the blog post from the person who "led the GPLv2 enforcement effort against TiVo" than the definition of tivoization that exists in the popular consciousness, which I expect is a political invention of the community over time. The article says "At the time, TiVo was doing the right thing in providing what the GPLv2 requires — including the ability to reinstall GNU and Linux software onto the actual device" and "TiVo never prevented such reinstallation". There is a whole section "How Discussion Focused on Cryptographic Lockdown Generally" about where the cryptographic lockdown worries came from; it was years after TiVo, during the GPLv3 drafting process. They even link to resources about how to update Linux on TiVo devices, one of them mentions breaking the "encryption" involves modifying the "tivoapp" userspace binary in a way that looks to me like disabling checking of the Linux kernel hash.

Linus is saying that signed Linux kernels are a good thing (and I concur), the situations he was describing there are for Secure Boot based systems, which are explicitly designed to allow for software freedom. IIRC this happens in a couple of ways:

1. the UEFI firmware requirements set by Microsoft require the ability to disable Secure Boot, and ISTR also require or encourage the ability to enroll secondary keys.
2. the shim firmware built by a distro and signed by Microsoft and booted by the UEFI firmware allows a physically present user to enroll secondary keys, and then all the layers beyond shim support verifying things using those keys.

https://wiki.debian.org/SecureBoot#MOK_-_Machine_Owner_Key

Of course Microsoft controlled Secure Boot isn't the only kind of cryptographic lockdown in use today. The method used on mainstream Android phones is different and I don't know the details but I think it allows wiping the phone and then booting unsigned Linux kernel builds but I don't think it allows the MOK style setup from the PC UEFI world. The Apple M1 devices have yet another system.
You mean the (non-existent) health effects of non-ionizing radiation exposure?

The damage feels like heat at lower frequencies (sitting in front of a fire oh no!) and a sizzle at higher frequencies (sitting in the sun oh no!). Induction stovetops emit orders of magnitude less than a fire and nothing at higher frequencies. Essentially: they get hot.

The best advice I can give: if you can't take the heat, get out of the kitchen.

Yep, there was one near my apartment in Yaletown (Vancouver). I did quite the double take when I first noticed.
The hotter you want the water, the less efficient the heat pump becomes.

Modern heat pump systems use water around 30-40C, and make up for the lower temperature with massive radiators or underfloor heating (which is in effect a radiator the size of the floor).
This reminds me of a fun story. A few years ago at a cool lan + demoparty event called Instanssi they had a local FM radio station dedicated to the event. It was then revealed that hidden in that FM transmission was the private key to a litecoin wallet containing some coin. I set about to try and extract the hidden message, but didn't succeed before someone else armed with GNU radio had already decoded the SSTV image from the sideband broadcast. It was a fun challenge, and the person who won taught me a bit about GNU Radio. An amazing piece of software, and a fun memory!
Evasion of regulation. Not just from governments, however. From anybody who wants to control people without consent.

I love self-improvement. There’s many in this camp of “you’re perfect the way you are”. I don’t agree at all. I believe more in Kaizen, the idea of changing for the better. It’s similar to the ship of Theseus paradox where you slowly replace each plank on the boat, is it the same boat?

Knowing about your short comings is the key. Knowing you are lazy will help you be more productive. Knowing you’re depressed will help you break the cycle.

People typically say they wasted certain years of their lives. I would also say the same thing. I was stuck in terrible loops of internet addiction and playing too many video games while doing the bare minimum at work.

These cycles didn’t break themselves because I embraced my mess. They broke because I became aware of them in comparison to my larger life goals of getting married, having kids, getting a prestigious tech job, and retiring early.

Many of those behaviors still cast shadows of my life many years later. But the secret to it all is that I can become aware of them when they happen and disrupt my pattern to put me back on track towards my life goals. That way I’m not a total waste man most days, and do something worthwhile instead.

>I bought the latest Apple iTV box

Okay but...

>In addition to better privacy

I'd very much like a source on that. I filter and block everything (via whitelist) from my TV and streaming boxes. Apple hardware and services are by far the ones that makes the most connections in both amount of connections and amount of sources connecting to. A Xiaomi android box is on a far second-place.

IMO "Apple privacy" is a myth with no proof ever published unless you think Apple for some reason is a better data collector end-point. I don't believe they are and it is also beside the point. Data collected is staying collected forever which makes the collector irrelevant. They can always change their opinion - you cannot. Amount of privacy related info collected is the only thing that matters and since I cannot see the excact data collected there's only amount collected left. In that Apple is definitely #1.
