When selling hardware, unless you are extraordinarily dominant in a very large and highly competitive market (television manufacturing), care only about marketshare (lower-tier smartphone manufacturers), or have another revenue stream (game console sellers) generally speaking you should target 3x BOM as your final retail price at an absolute minimum.

That's just for hunks of plastic. For complex (not a hunk of injected-molded plastic) devices with high non-BOM costs, you should be targeting 4x-5x at a minimum.

Also, the 3x-5x rule is for bare-bones lean operations. If you actually want to make money, compensate your employees well, practice good environmental stewardship in the construction of your products, use a manufacturer that treats its employees with respect, and have a healthy business where you are prepared to weather future changes in the market, your BOM costs should be LESS THAN 20% of the MSRP.

The model is also different if you are a Shenzhen ripoff factory dumping goods onto the market through Marketplace Sellers or Drop-Shippers. But that is not a model compatible with long-term prosperity or worker satisfaction.
Labor gets more expensive, less labor is purchased. It is fundamental. Even with cuts it can be hailed as a success because of survivorship bias.

You should ask for studies to support an idea rather than assume the idea is good because nobody cites studies contradicting it. Most people know in the back of their mind you can't just raise minimum wage to $100/hour and make everyone rich. It's just a matter of degree. There will be some marginal cost of raising the price of labor. Whether it is shorter hours, fewer employees, or one less company that was otherwise on the bubble.

Trains. Lots of trains. Inside tunnels. On the surface. On elevated tracks. That interconnect in a network so you can get from anywhere to anywhere. On trains.

Because everytime someone points out mass transit is a solved problem, has been for over 100 years, everyone responds somehow saying "that's unrealistic!" or "eww gross you want me to sit next to someone else!"

Your initial question is linked to your final remark.

People think affirmative action is a good idea because they think that minorities aren't doing well academically because they don't have role models to identify with.
To be clear affirmative action is supposed to be temporary until the culture of minorities that do not do well academically as changed enough.

So paradoxically the goal of affirmative action is to reduce cultural diversity.
Every time there is an anecdote of someone speaking so many languages, there is no evidence on Youtube or anywhere else. I mean spontaeous fluency, not reading a story or telling two jokes. Like in this case, he speaks only French fluently on Youtube.

Now, for example, Martina Hingis, a former tennis player for those who are too young or too nerdy to know, speaks five languages according to Wikipedia. Well, she actually has interviews on Youtube showing impressive fluency in English, German, Swiss German, French, and Czech. I am absolutely fascinated by this.
I am pro-nuclear and agree that it needs to be shut down. Any nuclear power plant that wasn't built this century needs to go away, we should not be running any pressurized water reactors.

The latest generation of nuclear power plants are very safe and have passive nuclear safety which requires no active measures to shut down a reactor safely which significantly reduces the risk of a meltdown. The biggest problem with nuclear power is old generation power plants that fail and cause negative sentiment towards nuclear power. I really hope we invest in generation IV nuclear power plants which deal with reducing nuclear waste and adds even more safety.

I am guilty of triaging emails on the underground train in on the morning.

No one seems to have mentioned my perspective: Its not that I feel compelled to do this (far from it), its more that the commute is BORING AS HELL.

At least for London, the wifi and network is only available during the 30 seconds you are in a station (i.e. not in the tunnels), so more productive things that need a persistent network connection wont work very well (e.g. Duolingo, netflix etc). You cant even look out of the window since its in a tunnel the whole way! :-)

The other alternative to doing emails is reading cached news articles (I actually do this a lot - load up a series of 10-15 articles before getting on the train), or desperately trying to connect to the wifi then load a webpage in the 30 second window you have before you are back in a tunnel.

Or you can get paid-for Duolingo or download netflix shows the night before etc. Its all a bit of a faff though really, while your inbox is sitting there full of juicy unread emails from your colleagues in another hemisphere that you'll need to read at some point anyway .... too tempting to jump in and start triaging when your alternative is staring at the floor or the blackness outside the windows :)

I won't shed many tears for the death of fossil fuel power plants.
Right now nuclear waste can and should be recycled which would reduce the amount of waste: https://en.wikipedia.org/wiki/Radioactive_waste

Soon it will be possible to use most of the waste as fuel:
"...Fast reactors can "burn" long lasting nuclear transuranic waste (TRU) waste components (actinides: reactor-grade plutonium and minor actinides), turning liabilities into assets. Another major waste component, fission products (FP), would stabilize at a lower level of radioactivity than the original natural uranium ore it was attained from in two to four centuries, rather than tens of thousands of years"

http://en.wikipedia.org/wiki/Integral_fast_reactor

https://en.wikipedia.org/wiki/Generation_IV_reactor

While there are issues with nuclear power, the worry people have about nuclear waste is greatly overblown to say the least. The amounts generated are manageable and in a relatively short amount of time we can use most of this "waste" to generate electricity. (The same can't be said for coal waste - like just about everything else associated with burning coal, coal waste is an environmental diaster.)

Nobody owns the city, the city is a result of the people who live there at any given time. Renters and tourists pay plenty of taxes too, and they aren't riding the real estate lottery wave due to permanent long-time residents fucking everyone else over with zoning rules that are making the prices go insane.

Rather than blaming the company Airbnb for a city’s ills, it may be more helpful to examine why it has popular support in the first place, while family-only zoning is declining in popularity. Short-term rentals in residences were already illegal in San Francisco and New York; they were legalized to allow Airbnb because short-term rentals have popular support from voters. Single-family zoning was designed 100 years ago to create neighborhoods of families who were protected from the nuisances of the lower-class apartment “parasite”s (Euclid v. Ambler) and lower-class houses that were used to raise chickens and take on boarders (https://www.citylab.com/equity/2013/07/it-time-bring-back-bo... or https://www.amazon.com/American-Nightmare-Government-Undermi...). I think exclusionary zoning has been so extreme in some cities that it is beginning to lose its support among the middle class, for whom it is now more necessary to use their property as a business rather than only as consumption.

Edit: Related point: In some places, it is ingrained in our culture since the 1970s that housing should be a good investment. Low property taxes (Proposition 13) and zoning restrictions are designed to increase the private gains to this investment (https://www.amazon.com/Homevoter-Hypothesis-Influence-Govern...). A small change of use to short-term rentals is perhaps the next incremental step for house investors. It sucks for people who want to use housing as only a peaceful consumption good, but in my opinion that ship sailed a long time ago in Closed-Access cities.

> It's just an object that lives on the stack, not the heap.

That's not quite correct. A reference type might contain a value type field, in which case the value type will still live on the heap.

Conversely, a local variable's type might be a value type, and _still_ involve a heap allocation. For example, std::vector in C++ is a value type but the array storage is heap-allocated.

So it's really about semantics, and not memory layout. Accessing an lvalue with a value type produces a copied rvalue; with reference types you're only copying the reference itself.

> I just can't understand why people are so averse to letting situations play themselves out.

If you are getting evicted by your landlord so he can turn your apartment into an illgal hotel, you do not have the luxury to let things play out. You have to find new housing immediately or become homeless.

Most people, especially those who are poor, live life on a more day to day basis. Your home is connected to your community: the friends who support you, the extended family who provide free child care, or the elderly and infirm members of your community whom you check up on. Being driven out of your home through no fault of your own, so that your landlord can run what amounts to an illegal hotel no less, is a crisis, not something to play wait and see on.

It's not orthogonal at all. Nontrivial mutations to multi-word sized values are inherently racy operations that can lead to UB if you don't have restrictions on how value types can be used. D isn't memory safe; Active Oberon employs mandatory object locking on writes (which is a rather heavy runtime solution); Cedar values are either immutable, or always valid with respect to word sized mutations (as far as I can tell, unions, for example, can only exist behind a pointer indirection). Modula 3 objects are not, as far as I can tell, value types (i.e. they must be heap-allocated and mutation creates a new record), and those are the only types it has where a "tearing" mutation could invalidate the runtime representation.

So, I disagree: all of the languages you mentioned either are memory unsafe when you use multiword value types concurrently, have one of the restrictions I mentioned, or (in the case of Active Oberon) conservatively lock on all writes. These value types are not "unrestricted" compared to primitives, all of which can be mutated in-place without allocating or locking, or to heap objects, which can be updated atomically even for interesting values at the cost of an allocation. Moreover, the issue is intimately tied to GC, or more accurately to the programmer not having to explicitly keep track of whether objects are uniquely owned or not (which is generally the function of a GC). As a result, if garbage collected objects can hold references to nontrivial value types, there is almost no way to avoid this problem.

From the FAQ:

What if I lose my phone?

Many websites require a backup two-factor authentication methods such as SMS and TOTP (authenticator 6 digit-code apps) even if you are using a U2F security key such as Krypton. For certain sites that allow U2F only (such as Google Advanced Protection), we recommend having a backup phone with separate Krypton U2F key setup or a physical hardware key that you store securely in somewhere.

We are actively building a robust account recovery service with partners to solve this problem and make U2F/WebAuthn a viable "single-factor" login system. We hope this will remove the need for these backup methods that make your account vulnerable to phishing attacks. We also see this as a major barrier to wide adoption of U2F/WebAuth/2FA so we are eager to solve this problem.

No, these are vulnerabilities in the standard itself.

I outlined the arguments here: https://paragonie.com/blog/2017/03/jwt-json-web-tokens-is-ba...

It's an error-prone cryptographic design that needs to be replaced.

Blaming implementations for faithfully implementing a flawed standard is a stupid thing to do, since it doesn't solve their insecurity.

Some site uses a 3rd party service to "comply" with GDPR, these 3rd parties will have a pop up where you can disable tracking you don't want (even though it should be default of). I notice that at least a couple of these service simply won't work with 3rd-party cookie disable, so now you can get to content, because you can get past the privacy policy.

It's a little retarded that you can't opt out of tracking, because you don't allow a known tracking technology.

I would hope so. Anything less is not secure. (This is one of the basic "problems" with hardware authentication.)

However, the software model allows for pre-arranged cloud sync between multiple devices. Given how Krypton handles PGP/SSH this support isn't there, but there's no technical obstacle.

That does not make sense in this case.

The key is made by a company called Feitian (Feitian Technologies Co., Ltd), on Amazon. That's the original manufacturer selling directly on Amazon [1]. That's the only one available. Its about as authentic as you can get on Amazon. I'd rather buy it from Gearbest or Banggood but they don't sell this. And Google just sells it rebranded.

Though I won't buy this (I could use the BLE part of it), since for one it doesn't seem to be build strongly (overcome-able but still), it only seems to work with Chrome according to reviews (I use Firefox), and I'm unsure if Bluetooth is secure for this method, nor reliable. NFC should be fine, since its much closer range, and I have a YubiKey NEO but my phone doesn't have NFC, unfortunately.

Even 2035 is still beyond most current politicians' terms. 100% clean energy will take a lot of work and more importantly determination. The closer you get to the goal, the more it takes to cover another percent. And you never know who comes next and decides to kick all the plans to the curb and subsidize coal (hypothetically speaking o_O). You need to add some buffers.

Another problem is that nobody else (at this scale at least) got there so it's hard to anticipate all the challenges. Germany, normally at 36% renewable energy, managed to reach that magic 100% figure on a winter early-morning this year. But nothing close to sustained generation. And they plan to get to 100% in 2060+. So California, currently at ~44% renewable energy, could be the first to hit the sustained 100%.

Another problem is that everyone defines "100% clean energy" in different ways, by leaving some sectors out of the count. Will this target cover electrical power or also aims at replacing all non-renewable sources of power for all applications?
