Does anyone know what the tuition is for the Abbott preschool program that is mentioned in the article? My impression has always been that one of the reasons that teachers get paid so little is that class sizes are relatively small (e.g. 4 infants per teacher in NC). I personally think preschool teachers are not paid enough but I'm curious how Abbott is able to pay their teachers so much.
From the opening paragraph:

>"Messaging app Kik staked its company’s future on bots and “chatvertising.”

then:

>"Kik pivoted to blockchain technology."

Is there actually any logical pivot from chatbots to blockchain? I am wondering what of your core tech in the former could allow you to pivot to the latter. Or is this simply grasping at funding?
I didn't mean the stories are purely political, only that they lie at the edges of what some consider to be too political. I don't think I'm working against the mods on this—mostly it's that some stories seem to disappear, either with or without "flagged" appearing, and I know as a community member I was surprised to see how this could happen (1) quickly and (2) to stories that were previously very popular. I am hoping to build a tool that will enable other people to see what they might be missing, in part so they can partake in these discussions, and in part so they can be more aware of how the system works.
This solves one aspect of the gerrymandering problem. The problem is that there are multiple aspects.

As one example, people want to both have majority-minority districts and avoid situations in which "specific populations of voters" (to quote the article) are concentrated into a district. These goals are often opposed to each other, especially when the minorities involved skew toward one of the two parties under consideration.

So it's quite possible for a redistricting plan using the "I cut, you choose" process to end up falling afoul of Section 2 of the Voting Rights Act by diluting the voting strength of a minority...
>>Speaking for myself, back in 2013, I was excited by what I saw as its potential for micropayments on the internet. That is (and was) clearly wrong - it can't do the transaction volume, is too hard to safely acquire and use for most people, and is too volatile.

This is strictly speaking not true. Yes, the current implementation is not good for taking micropayments, but it never was designed for this. If you thought this, you misunderstood the scaling architecture of the paper. It was always likely an off-chain derivative was going to be necessary for that to be a thing (Lightning Network), even before the rise of and prediction of ASIC miners and explosion in general computing power making the original algorithm chosen look... not ideal. We just got here much faster than people originally predicted, which is about what you get when you try to predict computing power curves as a linear function rather than a step function.

Whether it's undervalued at $14k isn't for me to say and I don't think anyone can truly tell you in either direction. But BTC has scaled as promised, just not as people would have liked. Then again, that's not BTC's problem, that's people not understanding BTC from the beginning.

It has a very prominent role in pseudonymously exchanging large sums of money near-instantaneously, securely, recorded in a global and publicly-auditable distributed ledger forever. There's a great number of use cases for this particular method of funds transfer, ones that I use today and many do and find a lot of value in it, even over other cryptocurrencies (for now). Would I prefer everyone take LTC and cut my fees down? Sure. 75% of BTCs problems go away if everyone would just activate Segwit too, but that hasn't happened either for whatever reason, so, it is what it is.
This is so fantastic, I wish my gym would do this. Whenever I go to my chain gym, I try to find a cardio machine as far as possible from the TV's running CNN and Fox News all day. If I'm not able, I take off my glasses so I can't easily see what is happening and focus on the book or podcast I am listening to.

If and when I want to watch the train wreck that is cable news, it is very easy to do so - it would nice not to have it forced into my field of view when I'm on a treadmill.
> the image of zero must be zero, and that doesn't hold for (most) affine functions

It does hold, always, in the higher dimension. And I feel like that's the most important thing to clearly understand about affine transforms. The entire beauty of the augmented matrix is that you get a class of non-linear transforms in 3d by using linear transforms in 4d. The article was nice, I'm nit picking something that was nearly there. It'd just be nice to be one teensy bit more explicit about what's going on here.
I don't believe it is, necessarily. The issue is that doing this action requires the admin to re-enter their credentials.

In this case, any credentials work, meaning that if a "guest" user (semi-trusted by the account owner, obviously using the owner's credentials. ) were attempting to change these settings, they could bypass the prompt with a bogus password instead of the alternative which requires the guest to ask the owner to enter their password.
It doesn't reproduce for me on 10.12.6 either. It only works on High Sierra (10.13).

I've been thinking about this for a while, there are some cool things you could do with command-based interfaces.

My take on it atm is to have a flexible (should work if you mistype a letter) command-based interface which is both voice and text based, where you can perform commands like:

play songs from coldplay

set alarm to friday at 3pm

make list with words a, b and c. Give me a random item from the list

There are some tricky parts though:
- Should it be context aware? Notice how I, in the second part of the last command mentioned "the list". I think it should, and maybe even ask "which list?" in case there is more than one.

- How do you define commands in a way that makes it easy to add and compose commands, and reduces or eliminates the ambiguity for the parser?

- Is the kind of parsing you do in voice recognition similar enough to be compatible with text parsing?

If someone know about some tool similar to this, please let me know.

Also: "It's also important to take the time to really use the tool yourself, so you can experience what's annoying about it."

Even if programmers are willing to ask those questions, it's a two-way street, and users often don't know what to ask for, or what's possible [insert apocryphal Henry Ford quote about faster horses]. Obviously, asking those questions and pursuing answers is a key attitude, but maybe that attitude also has to be augmented by trying to dogfood what you're building for someone else.
I use a bunch of providers for different use cases:

My photos are all stored in iCloud because of the great integration between all my Apple devices. I have 2TB free from an old job but will have to switch to the 50gb for $0.99/month when that runs out. Also, I store my third-party password manager keychain in iCloud (I personally believe it has the best security).

The files I actively work on or have worked on semi-recently (school stuff, personal programming projects) are all in my Dropbox because I often need the files actually stored on my computer but also easily accessibly online from somewhere else. I only have 2.2 gigs of space, but it's fine because I'm usually storing plain text documents.

I use Google Drive for backups and any large files I don't need stored on my computer because I get unlimited space through university. This is usually an "upload and forget" type thing where I almost never go back and access the files, but still want them saved somewhere.

I use Youtube for saving video (I have a lot of drone footage). I upload hundreds of gigs of video to a private playlist. I don't need the original full quality videos, and would rather have ease of access from anywhere, so this works well.

> I refer you to this comment, which you should have seen by now. Court case, concrete evidence. No frivolous arguments please.

There are a lot of comments in this post so I did not see that. In this case, it does appear that the NC legislature did intentionally act maliciously to affect who could vote. That being said, I still stand by my position that an ID should be required to vote, and that it should be easy acquire an ID.

> Are you saying that ... it might be abused? But is it actually, in reality? Your "what if" isn't good enough without concrete evidence.

I'm saying that not requiring an ID makes it easier for voting to be abused. I doubt it's abused much because it would be too fragile and require too much orchestration, but I don't think it's nonexistent. I think it's one of many safeguards to help ensure that elections are legitimate.

> Enough double-think.

I fail to see how I'm being logically inconsistent. I simply asked for evidence which you did provide. Most of the time people mention vague events without any citations.
You have the power, but the system would like to check that it is actually you and not a malicious script. It is the compromise between running as non-admin and running sudo for ever friggin’ thing and running wide open to the world as admin.
> Even self-driving vehicles will not be able to compete with mass transit when they're both priced similarly.

I think there's likely to end up being a third option: Public transport with self-driving cars for last mile at each end. That way you have the convenience of door-to-door, combined with the efficiency of mass transit for the bulk of traffic.

There are also other advantages, like it expands the effective catchment area of stations, making them more viable even at lower densities. And the cars themselves can be much smaller and more efficient as well, since they don't need the range, and they don't need to be as comfortable if people are only sitting in them for ~5mins.

The article states that admins can suppress messages, including the ones that report that someone has joined.
> This has the advantage of /continuing to exist if Kodak goes away/, which is what you want as a rights holder.

If you mean the ecosystem can thrive without Kodak, then it sounds like you don't expect Kodak to add any significant value and I may as well use any immutable public record, of which there are already countless legally tested options.

If you mean that if Kodak goes away then the rights contained in their ledger stick around as a historical document, then it explains why they need a public and immutable ledger (and a decent third-party archival service), but it still doesn't require trustless or decentralized.

A blockchain works, in the same sense that calling a ride sharing service to take me to the coffee shop half a block from my house works. But I can just walk half a block instead. As far as I can tell, the blockchain doesn't allow Kodak to do anything that they couldn't have done 20 years ago if they had wanted, and it's much more complicated (and therefore much more expensive and error prone) than many other data persistence layers.
The X-Content-Type-Options: nosniff header is among the worst necessary things in HTTP. Browsers (I'm looking at you, Microsoft) should not have attempted to determine file content type ever, because they (and the operating systems that serve content) should not have been relying on the filename suffix to determine what to do with the content.

The ubiquity of problems on certain operating systems that arose out of treating the filename extension as the file type metadata for execution purposes has probably cost billions of dollars in damage.
It is much, much more efficient to invest in public transit to serve existing job centers.
I know enough about Bitcoin to know that its value is nonzero. In tech, nothing this unprecedented just goes away. Either it complements or supplants something else, but it finds a use case, even if that use case changes over time. My opinion is that the most important use case for Bitcoin is related to economic sovereignty. It gives people an escape hatch from the global financial system. The price is affected by speculation, sure, but it mostly depends on how many people use the escape hatch, and to what extent. Just a theory, I guess. Only the future will show who's right.
> Except bitcoin isn't speculative, bitcoin has real value

because zealots say so.
Maintainer of the tool here - this is definitely the main use-case. We produce container images that are used directly or indirectly (as a base image by other users), and the structure tests here are a way for us to define the contract our container exposes and test/verify that we continue to maintain that contract quickly and easily.
> programmers don't go far enough asking the questions

Please state the fact:
programmers are not trained, nor have the time to go far enough asking the questions.

Don't pretend that non-tech people are capable of doing anything tech-intensive.

I am tired of the unilateral narrative of "tech people really blabla...".

People are trained differently, and their time is focused on different areas.

It's a problem with American politics. While Penn Station falls apart, London and Paris have seen nothing but infrastructure improvements and upgrades.

There are of course many reasons for this, but I assure you not all human societies are clearly hostile to public infrastructure spending and anything that isn't private and for-profit.

In the years I lived in London I observed the Tube going from constant outages and weekend shutdowns, to later trains, more frequent trains, and new infrastructure projects like Crossrail. DLR, a conductorless system I rode daily,was only a few decades old.

As a NYer I'm deeply embarrassed by having seen first hand over 20 years the slow decline of the transportation system here. It's embarrassing when family and friends visit from overseas and display disgust and shock. NY comes off as wealthy and clean in popular media there, but the reality is closer to a Third World one.

A part of me thinks this is really cool tech and it would be amazing for anyone to be able to just hop aboard their personal helicopter and fly wherever they want, but then another part of me thinks of the future this would create, skies no longer clear, filled with objects buzzing around and what hell that would be, on top of the already stressful and crazy life we have now.

It's the kind of situation where I think I'd actually rather the tech never exist.
In order to avoid death by 1,000 cases of crumbling infrastructure, the US should redirect $100 billion in military spending per year to infrastructure spending.

We don't even need to make that redirect last longer than a few years to fund most of our pressing infrastructure projects.

And our military would still have a budget $300 billion greater than the next biggest military spender (China)!!!
