AI self study can certainly get you to the equivalent of a Masters degree, and much faster for anyone who is motivated, unfortunately I would never recommend that to anyone.

The problem is that even after years of working in the field you will likely be underpaid, and it won't be possible to find jobs in the field without a direct connection. Another problem is that if you want to go for a PhD to learn beyond that you will need to sit though years and years of useless classes that you have essentially already taken, just to check some boxes. I don't think anyone self motivated to learn things will sit though 6 years of useless classes to check some boxes or at the very least it will be terribly depressing wasting so much life.

At least that is my experience. The open materials for CS and AI are great though.

Well, there's etcd, consul, etc..

edit: i guess i should RTFA -- looks like they are going to build raft into kafka -- at this point, I'd think raft libraries are fairly mature.
No problem. A lot more Canadian engineering undergraduates find the whole Iron Ring and ethics stuff to be some kind of Koolaid than I'd like to admit. I am interested in learning more about that team that won a prize for the cellphone-tracking solution at airports though: specifically, I'm curious as to how they came across the problem and how said problem was framed. Framing is one of the tools in which entities get people to build surveillance tools like PRISM and the like by appealing to those people's sense of patriotism. The other big tool is money, and enough of it.
There are a number of Java libraries that implement Raft already -- it's a fairly well understood algorithm.
The document mentions using Raft for consensus and coordination - it's the same approach used by Etcd, Consul, Serf, RethinkDB and other systems. AFAIK it's easier to implement and understand than Zookeeper's consensus solution.

Unsurprising result.

I was so sad (figuratively speaking) when we moved from an older office - but one which had trees all around and even running water - to a very modern, but boring open floor glass paned antfarm-like building.

After some time I got literally depressed. Walking around the concreted block did nothing for me anymore. No trees, no water, no birds, no squirrels. Just cars and a lot of heat in the summer - and a lot of wind during the winter.

There are other proven solutions that can be embedded such as Raft.
I've spent at least 6+ straight months on iTerm2 3.x, kitty, and Alacritty (my current primary terminal), and briefly tried Terminal. Terminal is waaay faster. The only thing that's stopping me from using it as my primary terminal is the poor colour support and poor split window support (and setting shortcuts to go between them).

I'm from the US, so I'll add the caveat that this is answer is based on my foreign understanding and a British electrician may be better suited to answer this.

Your green wire would be what the US calls a ground wire, and what is more accurately called a Equipment Grounding Conductor (EGC). It's purpose is to bond all normally non-current carrying conductive parts of a system together to provide a ground-fault current path back to the source so that the overcurrent protective device can operate properly to open the circuit in the case of a ground fault. It is 100% a safety measure, and will operate as intended to open a breaker whether or not it is connected to the Earth.

Your red and black wires are both ungrounded conductors, and are the conductors which actually create the circuit that allows current to flow to power whatever you connect to the circuit. The circuit will work to provide current without the green wire. However, without the green wire, if either the red or black shorts to something, the breaker will not open and you have an enormous potential to harm someone or burn your house down.
A company that has an extra $100MM in cash will have a market cap approximately $100MM higher than the same company without the extra cash.

noego's point is that that $100MM might be more valuable if freed up to invest in a risk-asset, but not that is has no value whatsoever.

When I make a WinForms app in VisualStudio I just drag-drop controls, click them and adjust properties the way I want, then click the controls and write the code which is going to execute in particular events. I have never had to learn this, I didn't need a single tutorial.

Once upon a time I've just got a junior C# developer job (without knowing anything but basic C++ and SQL), were given a computer and a real task and implemented a reasonable good-looking (looking and feeling the way common to all the Windows apps) business app that went straight to production just in some hours. And I didn't need anything but intuition and the API reference. It felt exactly like playing Lego.

Despite I also know basic HTML, CSS and JavaScript (I've learnt during the WindowsNT4 years) I have no bloody idea of what to do to get an approximately same result with today web-based front-end technologies. I've seen some React code and it seems pretty extraterrestrial. What scares me is the amount of what I need to learn before I can produce a useful application. And it seems (and feels the scariest) Photoshop and the art of visual design are on the list.
Virtually all punctuation marks started as prosody hints, indicating intonation and pauses, suggesting how the text is to be read aloud. In fact you can argue that this is still the case: it was only later that we invented grammatical structure rules for them, and even those are applied only in certain contexts like professional writing. In casual writing, we tend fall back to using punctuation as prosody markers, for example: "Worst. Episode. Ever."
It was always a matter of luck. If there were ways to predict such a lottery ahead of time, I think the industry would look quite different today.

As with flash floods of rivers, the coverage of such events was complex. It probably affected some companies a lot more than others.

Anecdotally, it used to be an aphorism at Microsoft that if you hadn't made your first million by 30 (or was it 25?) you were doing something wrong. Certainly the demographics at Microsoft showed several clear waves of early retirements from stock booms and bonuses, and for a ~forty year old company the median age is still staggeringly young today, even accounting for industry ageism.

If it wasn't clear, I don't expect those flash floods to happen again, they definitely seem to have been flukes of luck. But I think it shouldn't be ignored that it had an impact on the industry demographics.
For sure, just making an example to show the pattern
They are both connected to earth at the same point. The big difference is that "neutral" has current flowing through it during normal operation, but "ground" only has current flowing through it in a fault condition.

Doesn't that just release the C02 again? Construction purposes might help, or any other way of sequestering.
Yes, on both counts. However, requiring zookeeper as a dependency is also a barrier to adoption and increases the operational surface area, so offloading consensus management to zookeeper is not without trade offs.
Hi icechai,

Our BC platform "VINBlock" is designed to keep the public informed of the "vehicle services" performed on the vehicle itself. e.g.: Carfax but alot simpler, factual, and free. CF isn't 100% factual, it doesn't tell you if the oil/brakes/tires are OEM or AfterMarket, or the front fender is OEM/new/used, or the registration type is "new, used, salvage".

Our platform brings out alot of problems consumers face when buying a car/truck on face value, by providing that information to you free but importantly as fact.

Idea is to bring value back into an asset that loses value over a period of time, but also educating the public on the car there going to purchase either from it's born date to the day it's sitting on a dealership lot.

There are other features on our BC platform where launching, e.g: payments, insurance policies, maintenance, dmv services, etc..

Thanks

Stop playing around. Nobody believes your insane story.
I don't think that's what happens in the JVM, you can google up the invokevitual + other supporting gunk/mechanism for this.
My favourite example is, of course, animating height: auto and width: auto. A detailed discussion on why it's not possible and the (rather insane) tricks you have to do to animate these two properties is here: https://css-tricks.com/using-css-transitions-auto-dimensions...
Yes. That's why this is possible, here the insulation is the air between helicopter and ground: https://youtu.be/DPNK7bc2qvM?t=125

If that guy was connected to the earth he would get fried. Note that you still have to equalize whatever potential there is between you and the system, like they do in that video. Same reason why you should ground yourself and the hardware before working on your PC. Ever had a tiny spark hit you when you touched something (neither you or that "thing" being connected to the electrical grid, just static electricity e.g. from walking on the carpet)? But without connection to ground the only thing that happens is equalization of the potential between you and the target but no further flow. If you are connected to ground on one side and to a source that keeps creating an electrical potential, like the electrical grid with a power plant somewhere, there will be a continuing flow. If you are not connected to ground there won't be.

It looks like they’ve decided not to publish any non-English books [1]. It’s a pity – I much prefer reading books in their original language if I’m able to understand it, and I was even considering contributing some German books to their collection. Maybe it would complicate the publishing process a bit though since different languages have different practices for things like punctuation.

It's a floppy driver. I don't think much is going to change, besides making sure it still works
My thoughts exactly. I don't work with Kafka, but I do heavy work with Solr that also has ZK as a dependency.

To end users of whatever platform it is keeping together, Zookeeper is often seen as an unwanted dependency. The unwanted sentiment arises because maintaining zookeeper is not a gimme, and it takes additional knowledge and overhead to maintain. You need a quorum to be kept alive with an odd number (greater than one) of instances. So the question often arises, "how can we get rid of zookeeper?".
For the base protocol SNARKs, we're planning to do the programming in Rust, building on top of this little library we wrote: https://crates.io/crates/r1cs

We looked at a few DSLs but didn't find one that seemed to fit our needs well. I mostly focused on xjsnark, since it has nice features we wanted like permutation networks (to verify sorts/shuffles), but it seems far from production readiness.

We'd like to support DSLs like Zokrates as an option for writing dapps on top of the base protocol, though.

I'm with you, having grown up rural I can't stand being in the city. Makes me feel boxed in and anxious. But I've got friends who are the exact opposite, one who grew up in NYC and now lives outside of Boston who has to get back to NYC at least once every two weeks or she gets depressed. But I've also got a son who grew up here rural with me and can't ever seem to get enough of NYC. So... takes all kinds, I guess.

> You'll never do that update right?

I resemble that remark! Yes, procrastinator here. ;-)

The thing is, his code is plenty good for now. Even if I never make that update, the code works and people are getting useful results from it. There's nothing overly complicated about it either; I or anyone else could pick it up and easily make any simplifications and improvements whenever needed.

And this developer is working on far more important things for the company, mostly in C++. I made the call that it would be better for our business to let him get back to that, since any improvements to the JavaScript code style on this internal tool simply weren't that urgent.

But I do appreciate the reminder and I will get to that update soon!
/r/dataisugly is a pretty good resource for similar charts.
But not much closer, if content, rather than delivery, is the pressing bottleneck.

My experience has been, that of the few first-tier astronomy graduate students that aren't mistaken about the color of the Sun, as many learned it in seminar coverage of common misconceptions in astronomy education, as learned it in their own atypically extensive and successful astronomy education. Current content is really, really bad. A "Primer" will require much better.

AI doesn't help much if your large textbook publisher's science education content is written by inexpensive liberal arts majors with no science background, consulting with "scientists". If one instead uses science graduate students, double majoring in education, with misconception lists in hand, you might get that Sun color right. Maybe. And interviewing researchers about their own research areas is even better. But...

Say you're writing a children's picture book about atoms. What magnitude of domain expertise support do you need? How about a small room full of MIT physics professors? Is that enough?

Can you see a bare atomic nucleus with your naked eye? Why not? Did you just now say too small, rather than beyond-violet "color"? That much is easy. But what if you wish to discover that a couple of atypical atomic nuclei can be seen with your room-lit naked eye, can be made to brightly fluoresce visibly (a multi-step spin-isomer decay, with one step visible)? So you can include a photo, of a glowing green dot in a vacuum vessel, in your picture book, to reinforce that nuclei are real physical objects. My experience has been that a room of MIT professors, most with some nuclear physics background, is likely an insufficient gathering of expertise. Unless it's a lunch for a visiting professor, whose focus is nucleus simulation, who self-describes their focus as a (with emphasis) "small" subfield, and who perhaps thinks all this obvious. Reflect on that: A room full of MIT physics professors is insufficient domain expertise to write an excellent children's picture book about atoms. How might we then go about writing a Primer, if it takes such an awesome gathering of expertise?

Before Primers can be airdropped, they need to be written. And I suggest we're not yet even at the point of recognizing and acknowledging the primary challenge there, let alone scoping, funding, and addressing it. It's not pedagogy and ed tech that's blocking the road to a Primer. It's the sciences. And their incentives and funding.

It's something I'd love to be working on, but finding people to work with has been a challenge.

Wealthfront is not going to be loaning out money from their sweeps product to margin borrowing. Instead they will have a larger partner bank which offers then margin loans, they then mark up the interest rate and pass it on.

They do not have the accreditation to be issuing loans based on deposites. Thus why their banking product is a sweeps account.
The debate mentioned above was in 2012. That's many years ago, long before any recent "jingoistic bend", so I don't think it's relevant. Actually I don't see how it would be relevant anyway, since it has nothing to do with his actual argument in this case.
Repurchasing shares though is better for him than dividends. Decreasing the supply of shares, which increases the per share price, can often be better for investors than getting the cash directly.
When you talk about "electricity" you need to distinguish between "current" and "charge carrier." Current is the amount of charge that flows through a point per second. The charge carriers are the electrically charged particles that actually move. Where current goes is a matter of what we're trying to do with a circuit, where charge carriers go is why we need ground.

What a voltage does is pull or push the charge carriers. When lots of them flow, you have a current. Conductors, like a wire or ground rod, are full of free electrons to act like charge carriers (kind of like a pipe filled with water, the voltage is a pump that moves it).

The duality of pulling/pushing charge carriers is why we need a circuit. In order to push charge carriers, we need something to pull them from (a source) and somewhere to dump them (a sink). When we have no source and no sink, charge carriers have nowhere to come from and nowhere to go.

Ground is a convenient source/sink for charge carriers because it's roughly uniform in charge and huge, so pulling tons of charge carriers from it doesn't impact it greatly.

And it's not that charge carriers are always flowing back to earth, but back to their source. That's why ground is sometimes called a "return path." To move a charge carrier, you need to give it potential. It will lose that potential and return to the point of lowest potential difference from its origin - which is its origin.

But that said, for things like AC power, the charge carriers aren't actually moving very far at all and have a net displacement of 0. They vibrate adjacent charge carriers, and we convert that vibration into unidirectional (DC) voltages that can push/pull from local sources/sinks, be it the literal earth (mostly for safety ground) or a small plane of copper on a PCB.
Well the actual decision-making tends to be more important than just what one knows. A pile of cash seems more indicative of investment paralysis than some grander strategy. Like, "we can't figure out the best investment to make with this money, so the safest thing we can do is hoard it until we come up with a better idea".
Here's a section of that debate: https://twitter.com/garrytan/status/1133942478501888000
I like this, I even wish it had a name because I have observed it frequently, but upon some reflection it really only seems to be the product of certain organized situations and perhaps even just an artifact of our own pattern recognition. Are these new collapsed systems really less complex or just easier for our brains to think about? Natural(chaotic) systems certainly don’t seem to follow that logic unless I’m mistaken. Thinking of a river system, it seems that it is just in a state of flux, making little wins across the system all the time, but also becoming more complex due to inputs. If we consider a star system I have trouble identifying how the system doesn’t become permanently less complex as energy is radiated away over time. (Although I’m clueless on how to actually model either sort of complexity appropriately)

That said, it appears to me that as soon as we start to tread against entropy we might notice this phenomenon cropping up. Life seems to “collapse” on new designs and human understanding too seems to collapse, but in both cases it seems that only the system complexity collapses, not the entity complexity. I think that the collapse of the complexity of the surrounding system is the result of outside stimulus causing additional entity complexity to be added to the total complexity. In a stable, complex, system this has the potential for massive system destabilization, but it is not certain and it doesn’t seem to be the nature of complex system themselves to inherently collapse on less complex states, rather it is the result of stimulus. Moreover, if we look at total complexity, does it really become less complex or does the complexity just shift from the system to the entity?
