And I think he's heavily overrated because he presents well.

For one thing, his basic premise is not really much different from Engelbart and Kay.

For another, he doesn't propose specific processes or nuts and bolts design. The thinking trails off after "and then we make it more interactive..." Again, Engelbart did this. We've incorporated some pieces of it. We can still refine things. But the design problems always exist in the realm of compromise - if we automate more, we also have to specify more. General purpose solutions tend to fall back towards tried and true. When you put up a slick interactive demo, you have the benefit of being able to solve a very small problem, very precisely.

You know what UX problem needs the most solving? Documentation. You made a thing to automate a thing. But you didn't document it. So it's too non obvious to bother with. So it doesn't get used. The best work that Victor, Case, et al have done is fundamentally a form of documentation, not expressive tools. I've seen lots of folks try to take the lesson to heart and make their app more like that documentation. But it's a mess because it tends to leave out some necessary level of power or performance to be a good tool. It's extremely expensive to add the interactivity in many real world cases.
I see view (or screen) as something that maps to a route. It's true it's definitely a component.

I feel adding vocabulary like this to a system can help with understandability. That's the point I made with a "feature". It's something that could fit between views and components.

Atomic design (http://patternlab.io/) is close to this idea.

Thankyou for engaging.

That's dissembling. The "difficult conversation" was about Prop 8 and Brendan Eich's views on gay marriage.
It actually drives me crazy that any application should feel it necessary to implement its own tabs and window layout.

The OS clearly could provide a way to group any number of unrelated windows with tabs, full screen or not, in any tiled arrangement, with more than a lousy 2 splits that are vertical-only. They just don't do it, and they've had decades to add what amounts to some rectangle management.
My take on multitasking is that it mostly doesn't work, at least not for cognitive activities. But, I guess it depends on your definition of "multitasking" and "working/not working".

There are, perhaps, some activities which most people can multitask at - such as, driving a routine route while carrying on a light conversation. (But even that might distract from one or the other) But try something more complex - such as even trying to carry on a simple conversation while driving in an unfamiliar area or when you're lost - and quickly you'll find you can only focus on one thing at a time.

So, my sweeping generalization of people surfing and talking simultaneously is that if the two activities are very unrelated, (different topics) it's likely far less attention is being paid to each than the level of attention you're giving to reading your single article.
I'm going to translate from teacher-ese for you:

"While my students normally exhibited a substantial amount of distraction in our class, I was pleased to discover that since they were all artistically-oriented students, an impromptu art activity was able to occupy their full undivided attention for an extended period of time."

You're welcome.
I don't think it's misguided at all in fact it gets to the very essence of what it could mean to be successful in a modern world. The ability to develop you on your own premises rather than the rest of the modern worlds.
The strategies humans use to solve it are not nearly so optimal in terms of number of moves. More like 50-100 for a typical solve.
Anyone who thinks they are a good multi-tasker is disillusioned. Multi-tasking requires context loading and unloading, which always seem to have some challenges associated with it that are less than obvious. Don't sweat it. Being able to focus on one thing is a gift!
Is WordPress Being Rewritten in Node.js and React?
I think he gave a good depiction of his experinece that prompted the switch. I personally understand and share the same frustrations.

FTA: Around OS X 10.9, though, things started going wrong. 10.10 improved a few of these things, but overall it just kept degrading. It’s slower, there are a lot of really distracting “features” I can’t seem to actually reliably disable: It’s tied into my phone, and my wife’s phone, so when she adds events I get duplicate notifications (deliver once being a fallacy, I suppose), disrupting me from my work. I disable this, but …
It harasses me every day to upgrade. It desperately wants to just upgrade whenever it wants. More and more it acts like the Windows machines I’ve had to support over the last 20 years, which is deeply frustrating.

It regularly does things in the background without asking, consuming all my bandwidth (again: most of my work is remote, so I’m particularly sensitive to latency.)

And yeah: I’ve disabled all these things. They keep getting re-enabled, and so it’s not hard to take the hint.
This article lacks data to actually compare these two.

There is a point at which the elites of any activity become so proficient that meaningful differences between them disappear. Competitions are then won based on factors seemingly outside the nature of the activity. These rubik solvers seem to be at a point.

Looking at the comments on this thread few talk of the actual solving. Most are concerned with the circumstances of the competition, I think because most here realize the differences between competitors are so slight that one must look to the competition rather than the competitive act to determine validity.

So I offer this alternative:https://www.youtube.com/watch?v=B5Zi054Fa5k

By increasing the underlying difficulty of the task to the point that even the elites make many mistakes during competition, the focus returns to the underlying skill.

Conversely, I'm using OS X Yosemite on a Dell laptop. (It started as an experiment: to see if I could get a working Hackintosh, solely for development. Now it's my go-to machine.)

I'm not getting any annoying notifications, or requests for upgrades (daily or otherwise). In fact, my experience is quite the opposite: this is one of the most pleasing computers I've ever used (having spent years on Linux).

Upgradeable RAM, SSD, wireless; real page up/down keys, matte screen. Most of the benefits of Linux, and even WINE works, for Windows software!
So your argument is: "...said nobody ever."

I haven't heard anybody in real life call black people dumb. So I could claim that racism doesn't really exist.

Personal anecdotes prove nothing. We are both biased. I can't see what harm is done by warning people about this stuff.

truly, truly hate those. I disabled all notifications and i am totally fine without them, and welcome the regained sense of control I have over my machine.

I dread every OS X update because of things like this. I've found it better to just not upgrade - which is only suitable for so long.
I don't think it takes that much to be more efficient than in other editors; avy/ace-jump alone already exceeds what I was using before. After mastering basic navigation and learning several other choice plugins such as undo-tree, expand-region, smartparens, evil/spacemacs if you secretly want to learn vim, I could see emacs already being more efficient.

The weird issues and workarounds are annoying, though.
Amethyst is a nice tiling WM for OS X... Given that all it does is reposition windows rather than draw them, it's not a replacement, and sometimes gets in the way with incompatible apps, but works well if you're not using 10.11's support of side-by-side windowing, etc. I do hope OS X gets more flexible tiling window managers, but I don't expect it anytime soon.
Millimeter wave imaging means any building can be made transparent, and your privacy within that building is a social construct.

Exactly!

Boredom is very very important early on.

It's something you have to internalize and become familiar with and not fear. Way too many adults try and make sure their kids aren't bored IMO and thus the kids start fearing it because they never learned what a powerful engine for reflection and thinking it actually become.

Thats something you have to train.

I don't understand how good programmers can have boring work.

Any work you have that's not interesting is work that should have be done by a computer for you. If your computer can't trivially obtain and solve the work, the interesting work clearly isn't done.

Just using tools or applying well-known solutions to known problems is boring, sure. But that's operational work. I believe our job is to eliminate operational work by building better (at the omega point, fully automated) tools.

Sure. They don't, but when they are just starting school they still don't know much about what is possible, and out there.

Little bit of guidance won't hurt. There is nothing intrinsic in child's wishes. No one is blocking their inner genius by guiding them to pay attention to learning maths instead of painting, or dancing, or vice versa.

Don Knuth: As you say, I've come to believe that P = N P, namely that there does exist an integer M and an algorithm that will solve every n-bit problem belonging to the class N P in nM elementary steps.
...
My main point, however, is that I don't believe that the equality P = N P will turn out to be helpful even if it is proved, because such a proof will almost surely be nonconstructive. Although I think M probably exists, I also think human beings will never know such a value. I even suspect that nobody will even know an upper bound on M.
...
The moral is that people should distinguish between known (or knowable) polynomial-time algorithms and arbitrary polynomial-time algorithms. People might never be able to implement a polynomial-time-worst-case algorithm for satisfiability, even though P happens to equal N P.

Few comments are about the solving because few commenters are actually cubers.

If you look at discussions of this on actual cubing forums, then you'll see that the differences between competitors are actually significant.

Edit: As a direct example of competitors making mistakes, Etter's 4.9s solve could actually have been trivially improved if he had done a U instead of U' U' U' on the 2nd pair.

What do you mean they don't know what is possible? They are exposed to all sorts of of things way before they start school. Through friends, parents friends, family, media etc.

Nobody is saying guidance is bad. The point is when the guidance become constant. It's not about some innner genius, it's not even about finding what you are are good at. It's about finding the engine that will allow you to become good at something which is a combination between many factors including parents guidance.

But it's completely lacking when parent's start pushing the kids to try out may different things almost as chores.

Build, don't destroy: Why I'm bullish about Lagos
I grew up very poor, this did not make me stupid and implying such is offensive. There are poor people who can work it out and there are those who simply are incapable.

Knowing people that are still poor, including much of my own family, it is very obvious that they're unwilling to apply themselves. They give in to the easy quick fix, even when actively told not to and shown a better path. They are largely beyond help.

The people I know will make just as bad of decisions if given money. They are poor because they don't think about the future, they don't not think about the future because they're poor.

XINU is used for CS354, the undergrad CS OS course (and has been for at least the last 2 years). A different OS is used for the undergrad ECE OS course; I think it may be Nachos, but I'm not sure.
I cannot help but notice that many of the charts used to show how we are getting so much less violent have a spike up over the last 5 years.

So if the argument that we are as safe as we have ever been is based on that data, it looks more like we were as safe as ever in 2010. And now we are going downhill.
Currently procrastinating on a project using Xinu at Purdue. Some of the systems are dead basic, which makes it really great as a teaching tool.

Moratorium will be a big waste. If developer has an idea and cannot start implementation immediately, the idea may not ever be implemented, he may not be able to recall the idea after the moratorium. If the new ideas are instead implemented in an experimental stream, immediate feedback won't be there.
If the gamma is expressed in terms of velocity, wouldn't that suggest that the momentum isn't exactly proportional to velocity?

Because otherwise you could say anything is proportional to velocity, but with another term which counteracts that factor?

Also, I thought the view was shifting to using rest mass instead of relativistic mass but I might have that backwards.

One trick that works for me: having separate devices for separate activities. E.g., I have a tablet that I use for long-form content and pretty much nothing else. I consciously know that I could pretty easily log in to Facebook on the tablet's browser. But since I've never once done it on that device, my lizard brain doesn't know.

I recently bought a new phone that feels physically different than my old one (Nexus 5x vs first-gen Moto X) and I haven't yet used Facebook on it. I think I'm going to keep it that way; I so far haven't found myself automatically going to do it the way I would on the old phone.
No, he was talking about vc-mode, which tries to abstract away all of the underlying VCS to make it all look like CVS or Subversion. Honestly, rms had a poing there, because vc-mode really should make git look like a centralised VCS.

>global inequality and poverty are growing.

Global poverty has decreased dramatically (halved in 20 years).

"Global income inequality peaked approximately in the 1970s when world income was distributed bimodally into "rich" and "poor" countries with little overlap. Since then inequality have been rapidly decreasing, and this trend seems to be accelerating. Income distribution is now unimodal, with most people living in middle-income countries."

I started using OS X in 2007 as a semi-successful attempt to run an HP laptop as a Hackintosh (can't remember most of the details). Jumped to Apple hardware because the experience was so much better back then.

I can't really identify with the writer of the article either. Sure, there are some annoyances here and there. But if simple things like 802.11n (we are on ac at home), sleep when you close the lid, etc. don't work, it's a no-go for me (I use my laptop for everything: programming, research, teaching, travel to conferences).

OS X has the virtue of having a good GUI, reasonable desktop security (app sandboxing, GUI isolation, etc.), good support for 3rd party applications, while I am still able to open a terminal.
I can't help but wonder how much of the new web metaphors revolve around sharing state and replicating GUI features that were largely solved in the mid 1980s. I just spent days implementing some JWT and OAuth code that largely reproduces what session cookies did in the 90s (while fixing security issues, I realize that). I've spent weeks implementing AngularJS code that basically does what a software transactional memory (STM) does, only with ugly syntax. I've spent my career learning how to get an environment set up and transpile code (on many platforms, not just the web). I may be getting very proficient at these things, but in the pit of my stomach I know it's all going the way of the dodo and that I am a glorified punchcard operator, because I've been through code deprecation before and know it's inevitable.

I think the solution to all of this is to get back to declarative programming and idempotence, which will largely eliminate the trap of front end scripting we've fallen into. We need to switch from the client/server metaphor to trusted and untrusted computing and move to a p2p topology. This would be better served by the stdin/stdout/stderr stream processing of UNIX where each component does one thing well without side effects in a hierarchy of concerns where language is largely irrelevant and we focus more on the data, probably JSON streams processed with jq or something like it. Views would just be thin wrappers over black boxes handling business logic. Right now all of the glory is going to top-down development and processes like Agile/Scrum, but if we look to history, most of the interesting innovations happened in bottom-up egalitarian R&D. Now get off my lawn..
I'm a fan of ARM for it's power / performance characteristics, and for the market competition it's bringing for Intel. (who needs it)

One concern I have is the overall expectations on ARM are more locked down than Intel. Look at Microsoft and it's ARM Tablet. Locked down, Win 8 App Store only. Android is largely locked down, unless you jailbreak, or get a development / standalone PC board or system.

The more prominent ARM devices do not offer the flexibility and openness your average Intel PC does.

Legacy software is a big part of what I see as keeping that door open. This latest round of Intel PC's is notable for the lack of documentation and or options to configure them to boot other things. [1] Not like it can't be done, but it's painfully obvious the only reason it can be done is the vendor left the option there.

They don't have to, and I get the feeling nobody really does want to. They just feel it makes sense right now for legacy software reasons. At some point, that equation will change...

[1] - Case in point, a recent HP consumer grade laptop. Got it, and it had Windows 8 on it, which at the time didn't make any sense for the use case it was purchased for. There was no meaningful documentation on how to enter the BIOS to set "LEGACY" mode. I literally poked around on the keys, until I found it. Scary. The idea of, "they didn't even have to provide that" hit home right then.
While the “views are many components” reply is true that’s not really the distinction. Views are React components that have state or other complexity to them. Components are React components that just consume props and return DOM that may reference those props but nothing else in your app (they won't look at state, globals, etc.)
They won't extradite for student loans. For someone that far in debt, leaving is likely the best option for them. They can still be sued though and I'm not sure how that works exactly when you're in different countries.
Since when do countries extradite for debts? I'm pretty sure you have to commit a crime, and the crime must be something that is a crime in the extraditing country as well.

> Isn't that a case of not letting developers rewrite anything? How did it got so outdated?

If you're writing (or rewriting) using whatever's hip/new there's a good chance it will be "outdated" within a few years. New languages and frameworks come out all the time and nobody is able to determine with certainty which have real staying power - but something that has been in [wide] use for 10+ years is much more likely to still be widely used ten years from now than something that just came out last year.

Think of it like music, people have been listening to Mozart for centuries - it's highly likely a hundred years from now people will still enjoy his music. It's a lot less likely they'll be listening to Taylor Swift (nothing against her / her music - just using her as an example of someone who's very popular right now).
