From article: “In his report to the public inquiry, Professor Luke Bisby said evidence ‘strongly supports’ the theory that the polyethylene material in the cladding was the primary cause of the fire's spread.” and “The ACM (aluminium composite material) product on Grenfell Tower incorporates a highly combustible polyethylene polymer filler which melts, drips, and flows at elevated temperature.”.

I am not a materials engineer, but it looks to me that bricks with more than 10% of polyethylene are likely to be flammable in the case of a house fire.

I don’t know whether the Grenfell tower cladding had filler, but it is common for the polyethylene core to be mixed with filler within the cladding to help protect against fire, for example the ALPOLIC A2 product mentioned in [1] has an image showing a table with:

ALPOLIC fr: Combustible ingredients < 30%. < 13 MJ/kg

ALPOLIC A2: Combustible ingredients < 10%. < 3 MJ/kg

And [1] says “Its calorific value is given as something less than 13 MJ/kg, more than four times the value considered to be of ‘limited combustibility’ in the UK”.

Above facts are why I think even a large percentage of sand might still leave flammable bricks (polyethylene is like solid petroleum, until it melts and behaves more like a liquid or wax with a viscosity depending on multiple factors).

While the term "petrodollars" makes sense prescriptively, saying that the KSA would be "overthrown" if they started settling transactions in something other than dollars is pure hyperbole. The macrobullshitters that keep throwing around this idea of ongoing US coercion are doing so with absolutely no proof. Sure, there's some soft power things going on, but they settle in USD because USD has been the de-facto currency for world trade (and thus currency reserves) for some time now. IF anything, we see a movement away from USD into a currency basket with a high weighting of USD over the coming decades.
It's just nice to see the people that you're working with.
To all the commenters who are complaining about item no. 6, remote message deletion: Yes, of course you cannot be sure that the message is actually deleted. But in my case I usually trust the receivers not to be evil, but I do not trust them to be exceedingly careful or infallible. Therefore said feature would protect messages in case their phone gets lost at some point in the future later than the expiry, or in case some third party gets access to their phone in any other way.
To me Mina and Zcash are interesting since they (plan to) use cryptographic arguments to show that chain states are valid, which leads to some nice features, such as better light clients. I'm probably biased since our own startup was influenced by them. Besides that, I'd say NEAR since it seems like the most promising sharded chain that's in or close to production.

(They weren't on the list since Mina hasn't launched quite yet, Zcash isn't PoS though it might switch, and NEAR isn't PoS in its current form, but will be soon.)

My personal perspective is that if a Three Letter Agency becomes specifically “interested” in me, I’m fucked. No matter what I do. Even if I fake my own death and live in a submarine...

What I can do, however, is take measures to protect myself against less powerful or sophisticated attackers.

Where I come from, “communications metadata” is required to be kept by all telcos and isps. This metadata is them “available to law enforcement” - which is not just investigations into child abuse and drug running, as the proponents of the laws made out when advocating for them, but includes agencies such as the Taxi commission, various local councils, and state fisheries departments.

https://www.theregister.com/AMP/2018/11/14/comms_alliance_me...

Using (trusted) vpns and e2e encrypted messaging will reduce the chance of a local council or a fisheries inspector being able to get as much information from my metadata as they might from non VPN and secure messaging using people.

(Of course, it might backfire and just paint a big target on my back... One potential privacy advantage of COVID and widespread wfh is that many many more people are using VPN tunnels for ordinary and mundane purposes. Adding extra hay to the haystack my needle is trying to hide in is a good thing. So long as it’s not Mossad looking for my specific needle...)

Lots of DLP solutions rely on MITM user sessions, so at least corps who implement those solutions have access to all their user data in the clear —which is fair for a Corp. but users not being hygienic about their data often use Corp resources for personal use and that can get vacuumed up in the process.
If you think that historians, philosophers, international relations scholars and the general public have 0 critical thinking skills, you could reach that conclusion.

Realistically though, this is not the case. Although many wars are built on lies that may be believable at the outset, the public eventually tends to understand and the mood shifts. We have seen this in Vietnam and Iraq more recently.

One thing they did do: if you bring up the power off screen (by holding power, or power+volume up, depending on model) then it disables biometric unlock, even if you don't power it off. Bringing up the power off slider screen is sufficient to force a passcode-only unlock.

In that article, from an 80 old day comment of mine, you did not understand my comment. You told me to read the article. You don't understand what I mean by justification. There is a difference between prescription and description. That article was descriptive, not prescriptive. You cannot justify universals if you believe only particulars exist. You can only justify universals if you are willing to accept a metaphysical reality and provide a grounding for the metaphysical. Not everything is proven in the same way. The scientific method is good for studying particulars, but it cannot prove a universal. For example, science assumes the laws of logic in its process, which it cannot prove or provide a justification for. Also the scientific method cannot justify the scientific method. You on the other hand will probably say "because it works." Something working is a value-judgement, and that is not independent of ethics. It also assumes induction and regularity in nature, but you obviously haven't heard about the problem of induction. Science cannot provide a justification for induction. Science will also claim things like we know things from observation or what is in the sense data. Did we observe that or sense that in our sense data? I would say not everything is proven the same way. You can use science for some stuff, but not everything.
Fun fact: addiction is a disease and not a choice. It is strongly related to trauma, ptsd, income inequality and other factors individuals don’t have a choice in.

Classifying someone as a “junky” adopts a cruel and unrealistic worldview blaming the victim and absolving a number of powerful actors of their role in contributing to addiction on mass scale.

Only a small fraction of that $17B would be spent on building the plant and hiring workers (1800 jobs is what I've read). Most is for the extremely expensive equipment used to produce the chips and that will be bought and shipped in from elsewhere.
I think everyone is aware that it's a different paradigm. It was introduced in the 80s as a way to have floating windows for the application and reuse the same tool windows for e.g. Photoshop without a parent window. But now even Photoshop has a parenting window. Almost everyone just maximises all their applications since Mac window management doesn't work. And everyone else has to install Spectacle or Rectangle[1]

I am attacking the paradigm. It has had its time. It is done. It should leave.

Mining a block requires a lot of calculations, calculations are done on computers, computers use electricity, and producing electricity necessarily produces pollution. Ergo, bitcoin is bad.

Of course, the estimates of how much energy is used are always a bit suspect. I've seen articles like this that just don't quote any sources at all, and I've seen a number of them that all ultimately refer the same reddit comment from a decade ago where someone made an estimate of the per-hash electricity cost. They then scale that up to the current hash rate and use that as an authoritative figure.

Of course, nobody adds up all the electricity used heating and cooling all the bank branches in the world, or the cost of the looping animations on the screens of all the ATMs in the world, or the food eaten by all of the bank tellers in the world. Single-book accounting can make anything look bad.

But aside from that, the real story here is that the proof of work implementation allows the bitcoin system to spend money on something that makes certain kinds of attacks difficult or impossible. Other banking systems have to protect against those same attacks, but they do it by using trust between humans, exhaustive reporting and accounting requirements, and so on. As a result, those attacks are easier than in the bitcoin system, especially when international banks are involved. That big scandal in Germany where Wirecard told it's auditors that it had €1.9B in a bank in the Philippines comes to mind. It turns out that they forged the documents in an attempt to cover up their failing business. Forging a bitcoin transaction like that is impossible.
This isn't a ploy, it's a feel good puff piece about someone finding a use for the wasted they're swimming in.

CFCs are much easier to produce, and better-performing (non-toxicity, fireproofing, etc) than the alternatives.

I read also that a certain amount of the CFC releases were apparently coming from illegal sale of heavy tars (industrial waste) for use as weatherproofing. Which is dumb as hell, but also pretty typical.
I agree that it's insightful. But I wonder if it often isn't "refusing to contemplate". I suspect that at least some of the time it's "I'd rather attack a strawman and win by default, rather than having to go to the hard work of attacking a solid position". That is, I think it's because people value victory more than truth.

There must be hundreds of Gameboy emulators now. I guess it's the equivalent of "Hello World" for emulators.
We grew 89% last month
In January, my startup grew its revenue by 89%. Based on our growth so far this month, we might end up doing another 90% this month.

We are in the range where most other startups would typically raise their Series A. However, with this growth, we will likely skip the series A all together since we've been profitable for some time now.

You're right that BTC has no commodity utility outside of "being money." But I think society needs money, as much as it needs an energy source.

Gold is one object that's served the money function in the past. It has properties (fungibility, durability, scarcity, etc.) that money needs. But it's "dumb" and cumbersome, as physical objects are.

Building digital objects that serve the money function is important. One solution is the centralized ACH/banking system. But this has drawbacks --- poor scarcity, high political exposure, etc. I view BTC as simply building a competitor. You get better money properties, at the cost of more energy, etc.

Is it worth it? I don't know. But that partly depends on how the future produces energy.
> That needs to be done once, by the app's authors.

Except...it also needs FDA approval as a diagnostic, etc., which is probably easier said than done.

Obviously it's easier to distribute an app than lateral flow tests -- but the latter are much more effective too.

Clearly, we should do both, and...

> Reducing spread potential by 24 hours when you've perhaps been spreading it for a week already isn't exactly a game changer, but it's still useful, especially if the only thing people have to do is install an app on their watch. Expecting everyone to obtain rapid test kits and test themselves daily is in general a non-starter.

This totally depends on your goals. For the individual with limited outside exposure, is knowing 24h before you feel symptoms useful? Absolutely.

For a hospital or other institution (school?), who can order in bulk, and then mandate, lateral flow tests every day before work starts and observe their correct use (without having to rely on self-reported app results), the tests seem much more useful.
Advocates of Electron sometimes claim that it unifies the look of the application across platforms. This should not be a goal. Most people are far more like to use several applications on one platform than use one application on several platforms. It is the platform that the apps should be conforming to, not themselves.

Yes, but with a deductible. This theft happens often enough that you will save money by paying the $250 upfront to prevent future thefts, rather than continuously pay $100-250 deductibles along with an extra $30/mth to insure it.

It is impossible to regulate and tax miners; they live in various countries and in some it is impossible to apply such regulations, if some countries will do it then minim will move to other places.

When you have an industry, you get a product that you can use. Mining energy consumption is just about how hard to make the mining, not a real limitation like in industry. It is like "let's make car building 3 times more energy consuming".

No, there is no misdirected anger, there are good reasons.

I sort of wonder why I see so much users complaining about package management in Python, meanwhile I'm having a fantastic journey since 2008 with it, with over 50 published open source packages. "Sort of" because I'm suspecting that the users in question just do not want to integrate upstream changes continuously, so, they expect the package manager to help them procrastinating on dependency updates, which has proven to lead to disasters such as npm install, and I'm kind of worried that this is the direction they have been taking.

But I admit I use setupmeta for auto definition of the version, and it just makes setup.py even better, but that's basically the only thing I like to add to setup.py, because it simplifies package publishing scripts. I haven't found any feature in pip to verify the gpg signatures that it allows us to upload packages with (python setup.py sdist upload --sign).

As for pattern matching is not specific to Python, it's available in many other languages and is a joy to use in OCaml, I see no reason why Python would not have pattern matching.
I think CHIP-8 is a better candidate for that title. But yes, Gameboy emulators are quite common.

Cynical view. Those made it easy to see what the manipulated fairly public mass of disenfranchised or disgruntled or actively evil Q/Trump supporters were discussing and planning. I’ll bet people like flexcuff guy and pipebomb guy weren’t discussing _their_ plans in such public forums. And I’ll bet there was a _lot_ of planning of the sort that used to take place in underground-public places like 4chan, which has now gone deeper underground and has much more stringent initiation rites for admitting new members. The sort of planning that involves manipulating and convincing “pawns” in their “it’s all about ethics in video game journalism” games to provide cover and take the fall for deeply serious shit...

Does that negate the original poster's point that "Making transactions, relaying them, validating them and storing them have negligible energy cost."?
