1/ Under the current conditions in the context of the quarantine, when virtual events prevail over live ones, you should still find ways to give networking benefits to your listeners.
2/ Put even greater efforts into virtual events organization. Be an active “fisher” in marketing by actively inviting prospective clients to join. In this regard, SEO is a net that helps catch whatever can be caught. Account-based marketing is a spear that helps catch the most specific fish, meaning the most valuable target.
3/ Fill in web design and content with empathy. Don’t be psychopathic, meaning do not be careless about visitors’ needs and do not offer them pure marketing saying simply “we are the best”. Be emphatic instead, meaning add answers to the questions your visitors may be interested in, illustrate your success by numbers, analytics, and support them with winning cases or positive feedback.
4/ Try to understand the psychology of your clients. Make them see that you offer the best solution to them, even better than their own, and convince them to make the right decision by demonstrating numbers and using psychological tricks.
5/ Keep in mind that every action you take in marketing should have a measurable result. Be a professional, watch analytics.
6/ Mind the difference and don’t take negative feedback as criticism of your personality. This is only a reaction of a certain audience to your specific action, not to you as a personality. Life is going on. Keep on improving and show greater results!
7/ Be the author of your life. Find time to do something big and worthy. The key to doing it is breaking it down into several small steps.

In part I was inspired by what I learned about mainframes. I don't know that much about them, but I do know that every single component is hot-swappable and redundant, so that's how I tried to design my application.

As a bonus, I have to design it simply, and the process of rewriting it several times helps that end.
> If I'm Evil Social Media Company and I want to leak your secrets to someone ..

Apparently I failed to be clear. The companies in question might not (and probably don't) have evil intentions. They could either be forced (and equally forced to shut up about it), or might not even be aware of it (or not to full extend).

As business PR/politics go, a business would likely present itself safe and promoting how it cares about user privacy (bla, bla, etc). It could even publicly voice opposition to any government's wishes to extend control over them. What happens in PR/politics can be very different (and involve very different people) from what can simultaneously be dictated behind close doors in the name of compliance, national security, or whatever.

You are correct. You are indeed trusting the creator/owner of a private key with your data. It's also true that there are plenty of ways in which this trust can be violated. But to me, neither of those are what I have a gripe with.

What bugs me particularly, is that RSA intrinsically has an ability to put in a backdoor that is just as difficult to detect/determine for an outsider/user, as it is to actually break that key. What bugs me even more, is that I pretty much never hear anyone talk about that, or people countering with how there are easier (but harder to hide) ways to "break" RSA cryptography.

Maybe, in particular after Snowden, the premise of trusting the creators/owners of private keys just isn't good enough anymore (if it ever was in the first place).

The point is not that a bad actor may have six other ways till Sunday to be evil, but that the ability to add an undetectable backdoor is something I don't like for a public key scheme that still underpins the security of a majority part of the Internet today.

I guess time will tell if that was a mistake or not.

Online Whiteboard for Devs and Designers
Individual home ownership is not a good metric for the state of the middle classes, and the exception Germany illustrates it well: With renter-friendly regulations and high shares of public or semi-public (cooperatives etc.) ownership of homes, there often is no need to own housing, neither for financial nor for security reasons. In fact the rising home ownership rates in Germany are a symptom of the detoriating situation of the market, leading to more gentrification and rising rents in many regions.
Yes, are bodies are wonderful and still mysterious miracles of spaghetti code.
The problem is that you need to charge market rate, which the state then taxes as income. I would think it's unlikely to save you money. (If you don't charge market rate the tax office will either assume it's a gift and tax the renter on the rent saved or assume a market rate for income tax purposes)

> All you need is "x=x" to make a copy:

Your code is illegal Python on two levels.

- Lambdas in Python do not allow assignment at all.

- Variables in Python cannot be assigned using themselves in their r.h.s., without first being assigned something else, because Python's scoping is strange.

You serve well as an example of a programmer that does not understand Python's semantics here, because they are very counter-intuitive, and you also serve as an example of a programmer that does not understand how scope works at all, even if your example be worked into something of valid Python syntax:

thunks = []
for x in "abcd":
def thunk():
y = x
print(y, end='')
thunks.append(thunk)

for thunk in thunks:
thunk()

The output is `dddd`, not `abcd`; the `y = x` part is completely irrelevant in this case, for when the thunk is called, `x` has already been re-assigned, and so `y = x`, is assigned the new value.

Again, `x` is re-assigned on every new iteration of the loop, as such the `x` in every single one of those thunks contains the value `x` had at the last iteration of the loop when the loop completes.

There are many ways to solve this issue, such as the one I initially gave, but yours isn't one of them and that you thought it was shows the counter-intuitive nature of Python's behavior here.

> ("list" is a builtin, so not a good variable name.)

Which would be another problem with Python's lack of scope. Shadowing the names of library functions and constants is not problematic in languages with proper block scope.

It turns out that a lot of surprisingly impactful criminals never really figure out how to launder their money. Ulbricht appears to have had no real plan for how to actually benefit from his criminal proceeds, instead enjoying the feeling of being 'bitcoin rich' whilst living an unremarkably lifestyle.

Paul LeRoux seems to have also been a bit like that, albeit more successful at the laundering part. Nonetheless, when he was finally caught it turned out most of his wealth was in the form of precious metals under physical guard, and IIRC there was some sort of dispute over theft.

The anti-money laundering system has some questionable tactics in it: it grants virtually unchecked power to regulators and the US Treasury to squash whoever they like for whatever reason they like, and those powers were badly abused under the Bush administration. Think punishment without trial for people who criticised Israel, stuff like that. However it's an evolved system that does appear to raise the bar to serious organised crime.

- If I watch FPV while someone else is flying, I feel dizzy. It's not as fast as in VR, but still can happen

Friends who tried had the same feeling.

There's something in the connection between visual movement and your control of that movement via stick that helps alleviate dizzines.

Hope that helps in case you were wondering!

>Proof if work is a solution where you do not have to trust anyone, as the block is won by the person who finds the right math result, essentially a lottery.

The same applies to Eth2's PoS network, as block proposers are randomly selected with on-chain randomness. Block rewards are also not a major source of income for a staker on Eth2 — the majority of income (>90%) comes from simply attesting the chain correctly. This attesting occurs once an epoch for every validator, or every 32 blocks.

>Proof if stake is either really proof of work that is less secure and obscured, or more often dimply giving the creators of the coin the power and your trust....

PoS vs. PoW is really only a matter of how you ensure your chain can't be attacked. For PoW it's equipment cost, burnt electricity, and opportunity cost for losing rewards due to attacking the chain. For PoS, the security is ensured through a high-enough buy-in cost (32 Eth), and penalizing attackers harshly through slashing.

You can imagine how expensive it would be to accumulate enough Ether to attack the current PoS chain. There is 3.3 million Ether staked across over 100,000 validators, and one would need more than half of that total stake to have a chance at attacking the network, a failed attack resulting in massive slashings. This is made even harder as the attesting validators are shuffled continuously.

I personally loathe the energy consumption of PoW, and believe PoS to be the future. The fact that hundreds of validators can be run on just 5 watts of power should say enough.

If all validators on the current Eth2 PoS chain were run on individual machines, the energy consumption would be ≈4.4 GWh yearly vs. the current PoW chain's ≈25 TWh — a 5000-fold decrease. This is decrease is in reality probably even larger since pools, decentralized and centralized, will be running multiple validators on a single machine which affects resource usage very minimally.

That doesn't resolve (at least not obviously to me) the ambiguity where you want to match a Point where the first value is equal to the existing variable x, while the second value is anything and you want to capture it in a new variable y.

I prefer the suggestion that appeared at one point where captured variables would have to be suffixed with ?, like this:

case Point(x, y?):

For those not aware, the solution today is that x must contain a . in its name by virtue of being a member of an object or an imported module:

case Point(something.x, y):
Aerobic decomposition, exposed to oxygen like dead grass on the ground, produces mostly CO2 and H2O (plus some other O based stuff like SO4, PO4, NO3). Anaerobic decomposition, like in a cow's stomachs, produces mostly CH4 and CO2 (plus some other H based stuff like NH3, H2S, PH3).

Rice is a grain.
The EU's model essentially assumes that everyone should be a net exporter, which is clearly insane.

It makes no sense at all to expect Portugal or Croatia to compete with the German industrial establishment. It would take massive infrastructure investment to make that even remotely plausible, even if it was a good idea - which it isn't.

The reality is that the Southern countries are best suited for tourism, leisure, and agriculture, not industry, and so will never be competitive with FR, NL, and DE on those terms.

But there are plenty of mid/long term opportunities for developing Internet and bio/med businesses and related primary research.

The EU could do more to encourage those. (It's making some effort, but more is always possible.)

Imagine I really like hamburgers. I might choose to $5 each week on a burger and be happy with the quality of a burger made by people who only make burgers.

The alternative is spending $4 a week so I could access a buffet with lower quality burgers (after all, it’s not their speciality) but also hot dogs, sandwiches, poke bowls and sushi.

Trying to convince me that the buffet is a better deal just because I have access to a wider range of foods when all I really want is a burger is not a winning argument for me.

Chatbots replacing apps didn't happen.

However, if your chatbot performs terribly bad in user tests, you may want to remove it from your platform. A good chatbot can do great, but a bad chatbot is bad. And it's not necessarily bad because of the technology, it's most likely simply a bad chatbot like many other chatbots. Making a good chatbot is not trivial and requires a lot of work and user testing.

Also, home heating. When can I buy something based on a fuel cell that will let me replace my oil furnace?

And there's the potential for buffering excess renewable energy. for now this problem can largely be solved by improving the electricity transmission infrastructure between countries, but it's unclear to me that this is sufficient in the long run. I dream of the Star Trek like future where the Earths energy is supplied from solar panels in the Sahara, generating hydrogen which is then shipped around the world.
(1) There are too many confounding variables to draw that conclusion from that data.

In complex systems accidents do not tell the whole story, one has to also look at incidents and the "safety culture" of the organization (i.e. ~ how they avoid failure and how they react to failure).

Aviation for example has The Aviation Herald, where one can see that there's in fact quite many incidents that almost never result in accidents. There's lots of literature on safety engineering in aviation.

What's the equivalent for the nuclear industry? I was admittedly not very interested in this topic, so I'm only aware of the descriptions from Perrow's "Normal Accidents" book where he reported on several incidents which were actually published by the involved organizations. They didn't inspire confidence at all, on the contrary they were downright scary (and much scarier than one can find on the Av Herald).

Maybe the nuclear industry grew up, but it's absolutely necessary to have transparency here. Looking at global accidents is like trying to map a castle through a keyhole.
They argue that the centralization of advertising forces almost all companies to offer paid services and that those services lead to the overall online experience being more expensive.

They conclude that "we should recognize the trade we’ve made from ad-subsidized media to ad-subsidized search and social networking", which I guess is a well-intended statement but somewhat obvious, right?

Hacker News threads are filled with users arguing that they gladly pay a lot just to avoid advertising.

Their last sentence

> Perhaps now we can forge a better understanding of the value of content. It costs money to produce, so it should also cost money to consume.

I think is important, but maybe not for their reasons. Current paid services are sometimes very overpriced, which is partly caused by the lack of easy and scalable micro-transactions and a missing understanding of what a specific service might be worth. On the other hand there are some great services that get underused because users don't think the up-front cost are justified.

The turn to subscriptions that we see in random tiny auxiliary applications is a great example of that. The developers of a small CBT-App I used for a bit thought they were worth 8 euro a month. They tried it a few months and then gave up, largely because they apparently failed to find a shared understanding of their value with their users.
