One problem with this kind of analysis is that you have to consider the possibility that the author knows about these tools, and intentionally structured their words in order to mislead them. Maybe somebody was trying to frame Pence. Or maybe not. The point is, this kind of thing is a very weak signal at best for many reasons (including the ones pointed out in the article).

What makes you think that they said that Twitter must be just? Why not simply should be just? Why would you not want a platform as large and integral to modern open communication to be just?
> Crossfire, Alex Jones and Gordon Ramsay need their own shouting as a service platform.

Jones already has one, but the problem is, not enough people listen to it. So he wants to get on everybody else's shouting platforms as well. He could make more shouting platforms, but... well, "a platform for Alex Jones and Alex Jones wannabes to shout at you" isn't really much of a compelling MVP.
Lots to unpack there, but the “favorable” margins and low required funding they offered are illegal to offer precisely because they preferentially attract poor, unsophisticated people and mechanically increase the likelihood of their trades blowing up.

This is why being the counterparts to all your client’s trades and using the public markets only as a source of random numbers to operate a gambling operation with a fig leaf of respectability is derisively referred to as a “bucket shop” and is broadly illegal.
I never thought Of it this way. Not once did it occur to me that these are nearly exactly alike in this way.

Just wanted to point that out because it is so rare to read something that nearly instantly makes you think differently

But that's because it's .com. Now, there are too many gTLDs, and companies will build their brand around their use of .io, .me, .cs, .es, etc. Just the other day I saw a link that caught my eye to studio.zeldman, and I had to take a moment to hover over the link to see if that was some new branded gTLD.

If they replaced the country code with a flag, that would be an improvement. If they replaced the carrier number with the logo of the company that's also not bad. These are UI changes and the one you proposed about the phone numbers are great :)

Its just wrong. For starters, you're advertising a service that you're not providing. Secondly, you're basically running a twist on a Ponzi scheme. Eventually it will get out of hand.... if your customers have an incredible streak of good luck but no real trades to back them - how do you pay them?
As I said near the end of the video, this is a research project meant to demonstrate the concept and a lot of engineering would need to be done to make it work generically. If a small team were to tackle the project, I estimate it would take about 2-3 years of effort.

That said, I prefer Python and only used JavaScript in the video because I had a large project done in JS that I wanted to validate the idea against to make sure it wouldn't just work for toy programs.
Ask HN: How can I find a remote part-time job?
Hi,

I have about five years of experience as a full stack developer specializing in Ruby on Rails. I'm also comfortable with JavaScript and front end frameworks such as Angular.

What I'm looking for is a consistent gig where I can work about 20 hours a week. I'm based on the West Coast in the U.S.

The trouble is it seems very rare to find a part-time job for an experienced developer. Anyone have any leads?
We're in the middle of the best economy in years. Why would a worker put up with that? Go someplace else. Whole Foods doesn't put stores in small towns. Anyone who works there has plenty of other options.
Heat transfer, though, is based on temperature differentials - if Miami is +7degrees every day of the year, and Phoenix is +20degrees only 117 days per year, the energy demands of Phoenix for cooling could very easily be much higher (energy lost through walls, roof would be much higher, as would mass transfer of energy when doors open.) This is irrespective of local construction. Add to this, radiative gain (insolation through windows) is not captured in the degree-days statistic, nor is humidity related cooling (condensing water takes a lot of energy!)

Current audience. What about a new young audience? What about the part of the audience that wants to listen to him on Twitter?

> That would be against Twitter's freedoms.

I think you should be able to fire your users for being assholes. But I do realize the slippery slope here. I could discriminate on race, political preference, smell, weight, sexuality, age, etc. and that causes me to label someone an asshole.

Now Twitter, the biggest public and digital town square of our future, labels you an asshole, but does not specify exactly why. The global media town crier goes around town telling everyone you are now the new village idiot. Even if you vehemently agree with their decision, this should give you pause: How could such a system be hacked by adversaries/what vulnerabilities are exposed? How much unchecked social/tribal power is held in the hands of the few? What would such a system look like if it is artificially/clumsily converged to a majority opinion ideology chamber? Then, will you still be heard by your audience if you have a dissenting/unpopular/asshole opinion? Not too long ago "homosexuality is not a mental disorder" was an unpopular opinion. Do you trust our current evolution enough to say: "We are there. We can now freeze our morals and views."
I was a trader at a big bank for many years. The tools and access I had there put me in a different class of trader that very few other firms or individuals can attain. There is such information and technology asymmetry in this business - its not worth trying to day trade as an individual. Buy and hold forever... only way to invest.
Then why bring up that seemingly incredibly biased comparison you saw? That's what's unclear about your post.
So, TLS 1.2 servers offer session identifiers in cleartext and client resumption sends them in cleartext also. Which probably means someone watching lots of traffic to Google can correlate users even as they move across ips.

TLS 1.3 servers send the session identifiers encrypted to the client, and then the client sends it back in cleartext, but each successful handshake will generate a new identifier; a passive observer will not be able to correlate sessions -- except for retries, but the service owner still could. In TLS 1.3, the server can establish a session ticket any time after the handshake is complete, so conceivably, the server could wait until it had some idea of who you are, and establish a token then which contains your userid. (Anyway, it could always associate a random session id with your userid later)

I agree that this feature is actually really nice. But I also agree with the other criticisms that its hard to discover.
That’s not what the word counterparty means. You’re thinking “internalization.” An internalizer is not a counterparty to the position (“I think you will lose money”) they are a counterparty to the order (“I have extreme confidence that you are not secretly running Goldman Sachs from that eTrade account and so your sale of 2 shares of Google is unlikely to be based on a material edge, and therefore I am happy to make you a market in Google at a tight spread and indeed at a price better than any market covered by Reg NMS, whereas I would not make this offer to someone I knew to be Goldman Sachs because they would gouge my eyeballs out. I express no opinion as to whether you make or lose money on this position; I’m ambivalent as to whether you’re selling these shares because you’re unwisely timing the markets, because your daughter needs braces, or because you spent three hours reading their 10-K; none of these constitute edge and none of them mean I am unlikely to successfully make markets on many hundreds of thousands of similarly situated trades with an average hold time denominated in milliseconds.”)

If I was designing the user experience for accessing content from a global information, entertainment, and commerce network that would be used by a large, global, non-technical user base, I would not use the current URL format.

I would wager the twelve character prefix "https://www."would make no sense to 99.9% of the users and should be the default for over 99.9% of requests they would be making any given day.

I am guessing Google has evidence that this is the case.
Ah, Tech Crunch... liberal click-bait strikes again. It's like NPR that doesn't sleep.
Interesting—though I'm not convinced that the IBM approach to generalizing computation would have led us to general purpose computers as we know them now. Sure, it was more general than what had come before, allowing some parameterization of behavior—but 'more general' and 'universal' may be worlds apart (I don't know enough of the details of IBMs machines to say how much though...). Or even an architecture technically capable of complete generality, but not doing it so well, may be worlds apart from an architecture based on a simple theoretical grounding of that complete generality.

Eckert it seems was inspired by Von Neumann whom he worked with on the ENIAC, and Neumann was an early appreciator of Turing's work on universal computation(from 1936)—no surprise that his eponymous architecture mirrors a universal turing machine not only in power but in form (i.e. "the concept of a computer able to store in its memory its program of activities and of modifying that program in the course of these activities"[1]).

In view of that, I'm inclined to give similar importance to Turing's theoretical work still. Maybe I'm overestimating the importance of the architectural insights it led to—but I wonder if, say, we even had the Lambda Calculus, but no Turing—would we have fully generally programmable computers as we do now (which are as general in practice as well as in theory, if that makes sense)? I'm not sure...

What I wonder is if they try to work on the features they claim to want so desperately (number one priority!) for years. But there probably isn't a lot of overlap between people who need gimp to be like professional alternatives and people who can decently code. In our IT study we had four major tracks and the people doing media design were notoriously bad at coding anything beyond HTML, and even that was considered difficult by most of them (the three other tracks were software, embedded software, and business -- the latter also infamous for the same reason).
I'm confused by your wording and by wikipedia. Watts are a measure of power, not energy. kWh is a measure of energy.
It looks like a very nice careful description, but where is the physical intuition? Where's the plots of tangent lines on a function at various points?

There's nothing wrong with the article (I think), I am just curious about the pedagogy and motivation for not immediately introducing a graphical conceptualization of a derivative especially for such a "from the ground up" exposition.

I do see your point, but you are comparing two very different things. HTTP is a protocol, JSON is a data format. In a lot of ways HTTP is highly composable because along with hypertext media types like HTML or JSON-LD it allows for composition of documents and applications across hosts and networks into the World Wide Web. Vanilla JSON can’t do this without a hypermedia extension like JSON-LD.
Aside from the economic physical reality (that is to say all pensions need to be financed from current stock of capital/labor), in Australia the government pension is generally funded through general revenue as a (kind of) means tested general social safety net.

It is not the same system as social security in other countries. You don't notionally "pay into" your account with variations on how much you will then be able to draw out.

We also have other employee pensions (though far fewer these days), and now the superannuation system (roughly 9.5% of full time earnings go into a compulsory tax effective defined contribution investment scheme)
Wow! Always good to see another Kiwi on here!

I don't see how you could enforce a hostname binding to some real world identity. Hostnames really need to have a non-ambiguous mapping from a name to a computer (more or less), but real world entities don't have that, without using really cumbersome indentifiers. Many natural persons share a name, so how do we decide who gets a hostname based on that; the same is true of corporate persons -- there are many that share names. Even if there was a way to disambiguate these things, it seems unlikely that the entity in charge of this would also want to rub a public registry -- so how do you make that work.
How can you do your taxes if your trades are not executed?
Some historical perspective: My understanding is that when Social Security was created, the average life expectancy was 67.

While this is true, I think it's a misleading statistic. The relevant figure, it seems to me, is not life expectancy at birth, but life expectancy at age 65 (because the latter determines social security outlay). In the 1930s, a 65 year old could expect to live for about 12 more years, while in 2010, life expectancy was about 18 years. That's a considerably smaller increase than life expectancy at birth during that time.

It seems to do OK in the short to medium term.
Those who are saying this change is to make things "easier" for certain non-literate users may be correct, but they should consider whether such a justification is desirable at all from a moral perspective.

No doubt all of us have at some point been forced to learn things that we did not find particularly useful or pleasant to learn at the time, but then later experienced a great "satisfaction of knowledge" when faced with a situation in which that knowledge became advantageous or even essential, and then proceeded to use it to better ourselves.

Imagine a world in which none of that learning took place; one in which you never have to think, everything you see and do automatically satisifies you and keeps you in a blissful state of ignorance. Who makes the decisions in that world; or rather, who can make those decisions? Who is in charge of your life? Not you.

Gradually reducing the motivation to learn, by making things "easy" and hiding/obfuscating anything that could be used as a starting point for more learning, makes for a population that won't think, won't learn, won't question or rebel. It makes them docile and easy to control.

Making statements like "ordinary users will never learn" is one thing, but explicitly making decisions to ensure that status quo is a horrible trend. It's quite a genius plan, and certainly used by organisations other than Google, but thoroughly disturbing.

I've said a few times before in the past: "knowledge is power --- they don't want you to have too much."

I see what you're saying and think it makes sense in a physics context where things like cellular automata could represent some important aspect of mathematics/physics that we only barely understand.

On the coding side I think abstraction has pros/cons. Yes it is nice to just use a module without really needing to peek behind the scenes, but there is an elegant way to abstract things (think of Linux commands as simple compiled applications that absorb and emit text that can be chained together with pipes versus the nodeJS leftpad fiasco. The latter showed that a lot of packages were just hacked together in a web. Again, contrast the original Smalltalk implementation of IDE, compiler, word processor, games, graphics, audio, networking...etc, that had a good bit of what Windows can do in 10k loc versus Windows which has an order of magnitude of additional code in just Microsoft Word alone. Clearly we've been abusing abstraction as these systems are beyond anyone's understanding when that doesn't need to be so. Chuck Moore of FORTH fame has a great interview where he points out that an OS is a non-thing that shouldn't be as critical as it is. I don't think he is 100% right, but he is onto something.
That's really cool. I struggled to get a good midi engine working on linux and even what I have still messes around sometimes. Plus the instruments, while similar, aren't quite the same as those old school midi tunes from back in the day.

I thought maybe my struggle was unique to Linux. Setting up sound drivers for recording, was fairly complicated even without adding midi into it. Though after the initial setup linux's audio production tools are fairly awesome. I never realized midi support had declined so much all over. It's nice to see projects that keep old technology alive, sometimes older, more simple things really do have appeal and it's always sad when things kind of vanish unnoticed.
