I feel like productivity could be gained by having more specialized developers going forward. Instead of expecting every programmer and new hire to be a master of everything and anything, hire a specialist. I think it would be awesome if every team had a html/css specialist. Somebody who's job is to take visuals and convert them into markup. Afterwards another dev can just wire up the js. We have at least one such person at our company and I always ask for her to join my team if possible when starting a new project. It's just so much more efficient.
I agree. She's a minority and the compassionate thing to do is say, hey don't bug me about it but feel free to use me as a role model so in X years we'll have 50% women in the role of your speciality and we can move on. I wouldn't force anyone to be a public figure but to disengage completely is denying there is an imbalance. Also, I bet as an Indian woman she's not going to deny there is a massive need for general improvement in health in safety? Maybe she's really lucky but I just read [1] this morning and was reminded that I, as a woman, don't feel safe alone in certain contexts in India. I can afford a private car and security but that certainly doesn't stop me wanting safety for everyone. What's she saying read to me like, "I'm from a supportive family and wealthy enough background to have made it, leave me alone in my bubble where everyone around me has everything we need"

Neat app, but curious why you aren't using WebRTC p2p?

I've always thought something like this using WebRTC + a (simple) way to independently check that no data is being sent elsewhere would be really cool.

Btw you could declare a content security policy for just your site since you don't load anything off domain https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP Good luck!
How can anyone discount so called 'conspiracies theories' so quickly when accounts of such atrocities are now mainstream knowledge?

Conspiracy theories are the sum total of everything that could be true, so consequently the "theory" parts are a dime a dozen.
This makes me wonder if anyone has thought to add microphones yet to the array of sensors an autonomous car uses. Things like "my neighbors alarm keeps going off when I go into reverse" and "there is an ambulance somewhere I cannot see yet" sound mighty useful (well, at least the latter example), but very hard to incorporate.
But the stock market - in general - has ridiculously profitable and powerful entities behind it. No matter what happens to investor confidence, ownership of Apple is going to be very valuable because they generate a ridiculous amount of profit.

Cryptos, on the other hand, are entirely based on investor confidence.

Can an arbitrager not simply hold both BTC and cash on multiple exchanges at once? When a price difference swings one way, sell on one exchange and buy on the other, without worrying about transferring anything between exchanges. When the price difference swings the other way, do it the other way round.

If price differences average in both directions over time, you shouldn't run short of either BTC or cash but you will make a profit.

If price difference average in one particular direction, you can notice that trend and transfer across in advance.

An initial investment is required, but that is true of any arbitraging activity.

I had assumed that this is what arbitragers have always done.

The real snag in net neutrality, and "saving the internet" in general is not in getting a bunch of pop-up isps. The real crux of the problem has always been in peering relationships. It's not that hard to start a wISP. It's not that hard to even lease telco copper or fiber and run a local wired ISP.

Right up until your local customer wants to access Google, or Netflix, or something in Japan or Europe, or anything that isn't one of your local customers. Then you have to find peers who respect NN. And you have to build some connection to those peers.

Peering is expensive. A little ISP running out of a local data center has to find some other little ISP nearby and they have to build a connection between their data centers.

Building a worldwide network of such ISPs is very expensive. Sooner or later, the two little guys combine with each other, then with two others. And then you get exactly what we had in the '90s, which leads to what we had in the '00s. Unless you get very luck and get some superpower that builds out the infrastructure without losing sight of all that is good and right in the world, you end up where we are today.

Oh, and you have to get the masses to understand the issues and penalize cheaters. Good luck with that.
But are the odds in your favor? I live in the DC area. What are the odds that the public ISP is going to be run better than WMATA, where trains are catching fire on a regular basis? Or the roads, which are chock full of potholes. Or the water system, where the system is full of lead pipe? Or the sewer system that dumps untreated sewage into the local rivers after heavy rains?

"Laundering" their BTC seems like a pretty easy arbitrage opportunity: you can sell stuff to Russians for BTC and then convert your BTC to dollars, in both cases avoiding the conventional fund transfer systems that the US gov't exerts control over.

I might be misunderstanding something about how this works though.

Why is that a weak argument? And don't you think its rude and unnecessary (trolly?) not only to say its weak but its literally the weakest possible?

Not to diminish this feat, but I wonder how the Phoronix benchmarks compare between an ARM cluster and a single x86 chip. Consider the OpenSSL benchmark.

A Sopine A64 compute module costs $29 and performs 15.05 OpenSSL signs / second [0].

An AMD Ryzen 1700 costs ~$300 and performs 986.73 OpenSSL signs / second [1].

So, if you spent $300 on 10 Pine64's, you would achieve approximately 150 signs / second, but for the same cost you could just buy the AMD chip and achieve approximately 6.5x better performance for the dollar.

That is actually surprisingly low. How many of those towers are due to georgraphic constraints rather than capacity constraints? Each town tends to have its own tower, and then a tower often exists between towns to fill dead spots. I can get 3g or 4g from almost the entire length of my state, and I can imagine in a few of those spots it's just me and a handful of others that are connected.
When I worked at an NOC for a fairly large ISP they told me a story of an intermittent outage that occurred randomly on weekends. Something was injecting insane amounts of RF interference on the lines. They tracked it down to the node, then the neighborhood. And then finally they found the culprit. What was knocking the network out of whack? It was some guys edge trimmer. The motor in it was injecting crazy signals somehow. The ISP bought him a new trimmer and promptly took pictures of this one and destroyed it. Never had an issue with RF again.
Updates are expensive if you reinvent them from scratch but cheap if you adopt an existing framework.
>If you don’t disclose that or surrender control when required by law, they’re not going to just give up.

But its trivial to manage several separate financial persona's (wallets) and generally amortize yourself against losing/revealing everything.

>and most other countries will go along with that.

Countries within the Western sphere of influence sure. Just look at how the US got that BTC-E Russian on holiday in Greece. But consider the fact that some countries have more to gain by destroying US financial hegemony than they stand to lose by their own citizens petty crime. Russia makes bitcoin completely unregulated. So you try to contain the problem by blocking Ruble/USD exchange. Then China follows Russia's lead. Now you contain the problem by blocking RMB/USD exchange? Pretty soon you've locked so much of the world out that really all you've done is lock yourself in.

In the near future there will be so many leaks that the US and the West in general doesn't have enough fingers to plug every hole.

Nomnompaleo clued me into the Instant Pot about 3 years ago and I've used it at least weekly since. Most appliances go to the graveyard cabinet, not this. Just polished off a turkey stew: Pepper, onion, garlic, mushrooms, bacon & 4 turkey drumsticks. 1 hour to cook 40min to cool 20m prep yields 4 or five great meals. Umpteen substitutions and variations of the above keep bringing me back. The device is still working flawlessly. Glad I bought a second pot and lid.
Of course the problem is that major parts of your argument apply to the Federal Reserve system also, as well as nearly all other fiat currencies such as the Euro, Pound, Yuan etc.

So exchanging fiat Euros for fiat Bitcoin means what, exactly?
Do you have a reference about changes in the amount of molestation, busted collarbones, after-school fights, or porn viewing happening to kids now vs. 40 years ago?

Even if there are such changes, it seems unclear to me that they can be attributed to kids playing outside unsupervised.

But my understanding is that most child molestation is by trusted adults known to the family (or family members), most kids nowadays (certainly by age 12 or 14) have plenty of access to porn (probably much easier than in the past), kids still fight during and after school, and injury rates aren’t especially changed. I could be wrong about though, I haven’t looked up precise figures.

Just making up a list of scary sounding hypothetical situations and anecdotes isn’t the best way to judge risk.

The biggest causes of death for children in the US are cancer, car collisions, drowning, gun homicides, and suicide. If we want to make life safer for children we should be focusing on reducing car use and using traffic engineering to slow cars down (ideally <20 miles/hour) in populated areas, pay more attention to home swimming pools, get rid of guns to the extent possible, and figure out what in the society is making teenagers so unhappy they would want to kill themselves (maybe has something to do with their lack of autonomy).

You are confusing terms. Efficient Market Hypothesis and Market Efficiency are not relevant here.

Operational efficiency in the investment market (trading exchanges) is the issue. Transaction costs, manipulation, spreads, unfairness etc. add cost for doing transactions.
Well, MSVC supports those eye candy features yes. But it doesn't implement the C++ in the standard conforming way. Name lookup, overload resolution, and templates and practically everything is not implemented according to the spec.

I love ByteBall, but also likely the required crypto intelligence. But AFAIK they are a relatively mature DAG tech, with oracles and smart contracts already working (P2P UFC betting being a relatively popular example). XRB is another promising DAG tech (which I currently own), as mentioned. I suggest you look into both if you're interested.

I'm big on DAG tech as I see it being the only form of crypto currency that I can buy my coffee with, without waiting so long for confirmation that it isn't worth it. Whether it can be a suitable replacement to blockchain though I don't know, it may be an apples to oysters type of comparison and one may have strengths where the other has weaknesses.

How did anything get into those wallets in the first place? If it involved any legitimate business or a known address, they know you had something and will follow up.

If it’s totally off the books, you need to flee to a few countries with lax banking laws before accessing it because you’ll have to explain either the income or non-trivial purchases (“how does a guy reporting $100k salary buy a $500k house in cash?” is the kind of thing which routinely catches small scale crooks).

Do any of that wrong, well, you probably lied to a federal agent and can face severe penalties for that alone.

Here's what "thin" means in practice. Imagine two different sets of digital objects: AlphaCoins and BetaCoins - they're identical in the say way physics professors say "imagine an infinite frictionless plane".

Both have a 1000 in circulation.

Both are worth $10 each.

Both have a market cap of $10,000 US Dollars.

But the market for AlphaCoins is "thin" (small changes in supply and demand make for really big price swings).

There's a run on the market and everybody wants to sell off their coins.

After a day's trading:

AlphaCoins price is $3 / coin.

BetaCoins price is $9 / coin.

For goods and services you'd call this the price elasticity of demand (You can change the price of medicine and people will keep paying it b/c without it they'd die - it's inelastic - the same can't be said for a snack bag of cheetos).

To me, this is the article's argument. That while these terms describe the same things across markets there are some big differences not captured in simple "market cap" comparisons.

Maybe a better analogy is two all you can eat restaurants (identical, yadda yadda) but at one you can use your full set of dining implements and at the other you can only use a fragile toothpick to eat your food with - and all anyone can write about is how the quantity of food in both places is the same.

I would guess it's probably your phone's speaker. As the call coming in, the phone fires up the speaker for ringing. The speaker induces a current.

GFCI works by detecting the difference in the current flowing between the hot wire and the neutral wire. It needs to work very fast (to avoid the human touching the wire getting electrocuted) so any slight difference in current would trip it off. The current induce by your phone's speaker probably causes enough difference in the current to trip it off.

You can run an experiment by turning off your phone's speaker for incoming call. See if the speaker is the culprit.

I'm thinking this is mainly an issue for the kind of people who store offshore wealth already (like the Russians this topic started with). Apparently there are trillions of dollars kept that way. They're generally not the sort who get stuck with public defenders, and my point is that cryptocurrencies could make that wealth of the wealthy even harder to confiscate.

I don't want to doubt the potential usefulness of the linked article to certain audiences, but I wanted to point out the following:

It's important to acknowledge that intuition from rotations etc. are crutches, and not substitutes for deeply understanding linear-algebraic constructions and their formal properties.

Linear algebra is not really about the arithmetic of multiplying arrays of numbers - it's about the nice algebraic things that happen when you're working with things that come with "linear" operations. The linear-algebraic things that permeate all of mathematics aren't "rotations matrices" and such, but rather "universal constructions" like kernels and cokernels, products and tensor products etc. We even have abstractions that precisely formalize these nice properties of the category of modules/vector spaces, such as abelian categories and linear functors. Any introductory reference on these will provide you with an abundance of examples where things with these formal properties naturally arise.
> Why is the fact that arbitrage is harder with btc a disadvantage

Arbitrage is the method by which segregated markets are aggregated into a single market with a common price; if that is harder you have segregated markets.

> And the fact that the "price" reflects recent sales rather than future sales seems, well, obvious, and identical to other securities/commodities.

The same issue is raised with commodity/security markets in general, but it's practically more significant when the market(s) for a product have significant liquidity issues.

> In theory our public transit is “locally owned and operated and is dedicated to serving the people” rather than shareholders. Yet public transit is almost uniformly awful in the US. If you live in San Francisco, do you really want your internet run by the same people who run the Muni?

Public transit is terrible for a specific reason. The majority of people don't use it which means the majority of people don't care that it's terrible and don't want to spend a lot of tax money on it.

But the majority of people do use the internet, and the funds would come from subscribers rather than taxes so you don't have to convince non-users to pay for it.
> But its trivial to manage several separate financial persona's (wallets) and generally amortize yourself against losing/revealing everything.

How does money enter or leave those accounts? If you started with real money, converting it into Bitcoin leaves a paper trail and it’s on you to show where it went for any non-trivial amount.

If you received Bitcoin, attempting to spend it has the same problem – if you didn’t disclose it, that alone has hefty penalties.

The other point to remember is that everything people describe looks really bad if there’s any hint to clue an investigator in. Most people are going to have some slip and this will all be used as proof of intent.

Recommendations needed- E-Learning platform for people to learn coding
Hi there, I launched my website (https://labex.io/) for newbie coders to learn FREE beginner level programming courses. There will be more courses coming next month including Python, blockchain, etc.

The thing is instead of offering video tutorials, I offer step-by-step tutorials and sample instructions and codes. Also I set up a virtual lab environment for people to practice and experience hands-on exercises. It is a virtual Linux desktop.

I could really use some advice right now. Not sure if people like this kind of learning pattern. Any comment is welcomed.
