Except it doesn't stop at 3. Then you have (copying from http://sourceforge.net/p/readable/wiki/Solution):

4. A \\ (aka SPLIT) starts a new line at the current indentation. If it's immediately after indentation (aka GROUP in that case), it represents no symbol at all (at that indentation) - this is useful for lists of lists.

5. A $ (aka SUBLIST) in the middle of list restarts list processing; the right-hand-side (including its sub-blocks) is the last parameter of the left-hand side (of just that line). If there's no left-hand-side, the right-hand-side is put in a list. This useful abbreviation from Haskell simplifies many common cases.

6. A leading traditional abbreviation (quote, comma, backquote, or comma-at) or datum comment "#;", at the beginning of a sweet-expression line, and followed by space or tab or end-of-line, is that operator applied to the following sweet-expression. Otherwise, it applies to the next neoteric-expression.

7. The markers “<∗” and “∗>” surround a collecting list, and MUST accept a list of 0 or more un-indented sweet-expressions. The “<∗” and “∗>” represent opening and closing parentheses, but restart indentation processing at the beginning of the line. A collecting list is only terminated by its matching “∗>” and not by a blank line. These are valuable for defining libraries and for short let-style constructs.

8. The marker “$$$” is reserved for future use.

Got all that? I sure didn't. I spent some time on the mailing list a couple of years ago and grew frustrated with this gradual creep of operators, which led to absurd code like this (from http://srfi.schemers.org/srfi-110/srfi-110.html):

let
\\
c $ cos a
s $ sin a
body...

I mean, would it hurt to add a couple of parens here and there?! Even Java has a few of them.

The others OK, but that's a little far fetched. Who gave a flying fuck if you had an early access Gmail account? Geeks? And I don't think it was some kind of envy generating strategy -- just the usual practice of an "invite only" beta.

The PIN issue is only in the deprecated KNOX personal. The managed KNOX (enterprise) doesn't use a PIN.

KNOX Personal was a failed intention to promote KNOX through the end users and only available in the early KNOX dev.

>Some people of means choose to drive luxury cars because they are powerful, comfortable cars with lots of safety features and bleeding edge technology.

Probably the kind of people who have never heard or entertained the notion of diminishing returns, and think that spending $200,000 or $300,000 on a car will get you much more comfortable and "bleeding edge technology" than spending, say, $60,000, and not just an extravagant design and the envy factor.

(I'm also not sure why buyers of luxury cars in the US in particular want "powerful" sports cars in a country where the maximum speed limit we get is a kindergarten level 70-75 mph).

(Btw, and whenever someone writes "everyone" for a social group, he means "the majority of them". No need to point out some exceptions to "disprove" him).
Performance Tuning – Writing an Essay
Urban light pollution: why we're all living with permanent 'mini jetlag'
If this really can do 19,000 MB/s read speeds, that is faster than DDR3-2133 RAM[1] (which I think is the fastest generally available).

SSDs have already changed the way people write IO intensive applications. Things like this will change it even more.

This is the same approach we're using at Wikipendium[1] for math-heavy article editing - Markdown with inline LaTeX math segments edited in a CodeMirror editor. It's cool to see others tackling the same problems in similar ways.

We use Mathjax[2] for rendering LaTeX client side, but have run into some performance issues as the number of math segments increase on a single page. Paperman seems to be using something called MathQuill[3], has anyone here tried using it on large amounts of LaTeX math? KaTeX[4] is another possible alternative, and certainly the best I've tried in terms of performance, although it's still a little lacking in terms of symbol support.

"Users apparently dislike this workflow so much that they don’t bother contributing at all: significantly less people are editing Wikipedia than did a few years ago."

To be fair, I think this exaggerates the role of the editing UI -- if the editing UI was that bad, then people wouldn't have contributed in the first place. The more common narrative for reduced participation is the growth of cultural issues which make it less rewarding to participate (e.g. http://www.technologyreview.com/featuredstory/520446/the-dec... ).

(Edit: Not trying to be negative -- the suggestions in the article sound cool anyway.)
This makes much more sense now. The article was weird.
In the enterprise space things like this (eg, FusionIO cards) are used for everything IO intensive where the IO payloads don't fit into RAM. Eg, virtual server hosts, large size DB servers.
Having worked with journalists, I'm still shocked that don't know SQL. It seems like a perfect fit.

As you say, dealing with the UI is fine. Dealing with the bureaucrats isn't. Having your account banned and your new article marked for spam by a very abrasive person, when trying to add legitimate content, rather than being supported through the maze of rules, as happened to a colleague the other day. That is a problem which stops meaningful content being added.
According to the book "The Everything Store", Amazon employees pay for the parking ($20-30 per day). Coffee machines are ancient varieties but it's better than past when employees also had to pay for coffee. You get the desk that is downright cheapest possible thing you can get. And so on...

If you are wondering how Amazon can attract any talent at all, the answer is that 70% staff is college hires that were promised significant stock. The caveat is that it doesn't even start getting vested until after 3rd year. Most of the hires leaves in about 2 year (attrition rate is being rumored as much as 70%). So their secret is feeding the growth engine on huge swaths of college hires that can be lured for stock options in distant futures with expectation that they will just leave before vesting starts.

Well, I do love Amazon. One thing they have got absolutely right is obsessing about customers. Everything starts with customers, period.
Take a look at the Wikidata project - it's designed for editing structured data.

Unfortunately I wouldn't say it is very easy to use - the Wikipedia editor is much easier. It's also completely unclear which parts of Wikidata data are used in Wikipedia, and where.

That means the Wikidata data is usually much worse than the Wikipedia data, even if it theoretically easier for machines to use.
You don't have any contact info in your profile. I would like to run some questions past you, if you have the time?
The tagline is misleading. This is just a markdown editor with something like MathJax dropped in to do LaTeX-like equation rendering. Nevertheless, the live-editing and download PDF features are pretty cool. Nice work!
Adobe owns their product space, at least since they bought Macromedia 10 years ago. So, customers since have been angry about the lack of features--but its just a business outcome. Bitter, bitter, customers.
That's because it's a higher-level abstraction than other web frameworks. Ripping out a layer and dropping down to a lower level of abstraction is always going to be a lot of work.

Empathy being flawed is a startling insight. But why then throw it out and go straight to abstractions?

I used to trust Amazon for the low price but these days I'm finding they have let loose all the 3rd party vendors. You will see several products who are falsely claimed to be sold by well known brands like Sony but underneath there would be someone in China putting that up. Many times they are fake and many times merchants play the tricks of putting it on Prime but charging 20-50% more. I feel Amazon has left customers in water because there is no way to know if merchant selling products is genuine and has priced it reasonably
"My management thinks he is A level player"... and yet he's "asking me to take a look at his compilation errors".

A-level players don't need help fixing compilation errors. In fact, A-level players rarely have compilation errors. Routinely writing code that doesn't compile (except for obvious typos) is the sign of someone who doesn't know the language they're using very well.

Wow: "For applications on Google Play that integrate this tool, usage is tracked" without even an option to disable that. Sure, it's open source so can be changed by editing the source code, but does anyone else find that kinda creepy?

e.g. if I make an app using 10 FOSS libraries, then I wouldn't want my app reporting to 10 different places everything which the user is doing.

Also, on the actual homepage for it (http://google.github.io/flatbuffers), the only mention of this call-home feature is buried at the bottom of the "building" page.

[EDIT] This is incorrect; see below comments about this tracking not being a call-home feature but instead just Google scanning apps submitted to the Play Store

Kindle Fire is a tablet you can buy for $100. Their phone is almost free. Sure, it's no iPhone or Nexus but if you flipped burgers at McDonnalds or moved carts at Walmart making $10K a year, these would be life saving. Remember half of the population in make under $50K. Also they make special kids version of tablet that is pretty awesome if you were working with little kids.

Public spot FX markets and OTC trading do huge volumes too.

Any non-anecdotal data supporting StrongLifts workout healthiness?
To what end?

I freely admit that my fascination with winged hussars is immature. That doesn't change the fact that Poland is a state in search of security like all others, borders countries it regards as untrustworthy (Russia and Belarus), and has a largely flat topography that allows armored assault by those countries.

Of course you can argue that being a part of NATO means that they are under the US nuclear umbrella and therefore it is non-rational for them to invest money in military hardware. However a nuclear umbrella depends entirely upon the protector nation being able to credibly communicate that it is willing to use weapons in the defense of the client nation. This gives the client nation incentive to demonstrate that it has a spine of its own and is willing to pay a reasonably high cost to defend itself. Otherwise, who would believe that the larger nation would defend the smaller when push comes to shove?
Why else would Poland have gone to war in Iraq?

The winged hussars are still silly, but a well-known elite cavalry unit doe support the narrative that Poland is a bulwark of the alliance against an assault from NATO's traditional enemy. Also, they could better support and possibly train their ally Ukraine.

Nesting an encrypted connection inside the traffic being routed through tor is what you would need to protect HTTP traffic from being manipulated and/or monitored by an exit node.

So instead of doing (you -> tor -> internet), do something like (you -> tor -> VPN -> internet). To be even safer do (you -> VPN -> tor ->VPN -> Internet) that way your ISP isn't aware of tor traffic and the exit node cannot manipulate requests.

Easiest way to accomplish that is with a VM. The host has a VPN connection, force route the VM through tor (with something like Tortilla) and install a VPN client on the VM as well. This requires you anonymously set up the VPN running in the VM so there is no connection back to you, of course.
> I believe that if there is one thing humanity needs to do to get through the next few centuries, is to reject envy and stop taking finite games seriously.

That cannot happen as long as you want humanity to exist. Reproduction is the driving force, shaping everything from our behavior, including the search for status, which is an important mechanism in mating. If people didn't signal [http://wiki.lesswrong.com/wiki/Signaling], evolution would be a lot slower (or maybe could exist at all?).

Now, status doesn't necessarily need to be related to wealth, however for the past centuries, that was a reliable indicator.

This is really basic evolutionary psychology, and I encourage the author the check it out.

the measurable externalities of facebook are pretty minimal, considering it is _not_ the entire internet, and there are many other well known ways of commiting speech, and many ways of doing it anonymously.

For me the strong linkage that Facebook does with my identity (and between me and others) has great value. It's a public place more than a private one, and for private things I go elsewhere.

>You are implying that the only way to achieve the benefits of facebook is by operating like facebook. How do you know that a different system that provides roughly the same services, but without a central agent that sees everything and can influence everything couldn't have been invented instead?

A big part of the value-add in FB is the general assumption that "you are talking to this specific person that you have met in real life" (say high school friends). Some identification server at the least and centralisation.

> How do you know what opportunities we as a society are missing because of the dominance of facebook?

Genuinely curious as to any ideas you might have on this. Did you have anything in mind? Or is it just speculation.
They can replace some native apps. With Meteor, you can now use the same basic building blocks to build your web app, iOS app, and Android app.

Maybe you won't reach the same quality on iOS and Android as you would with native apps, but for smaller teams this can be a huge time saver, especially in the early stages of a project.

So in a lot of cases it's not so much "web app" vs "native app", as "web app" vs "no app".
I'm a bit confused. Is it actually calling home? That seems kind of unlikely, given that a) that seems pretty egregious for a library like this, and b) they said this doesn't affect the application at all beyond consuming "a few bytes".

Could it instead be just that Google scans Google Play apps for a string in the binary that matches the Flatbuffers version string format? That seems more likely given what the README does say about this. And it also seems more useful in general; Google would benefit more from knowing how many applications use the library than knowing how popular these applications are.

I go to abstractions because I'm a product of the enlightenment - I believe that the universe is governed by mathematics and reason, and the best way to understand it is to use those tools. I realize this does make me a bit of a weirdo in our post-enlightenment world.

Using emotions instead of reason suffers all sorts of problems. The most easily characterized, and shocking to the mainstream, are things like empathy being racist and sexist.

But there are deeper problems - emotions are often just plain inconsistent. We will feel different things depending on the framing of a situation, our own mood, relative status of other people involved in the situation, etc. This also makes "cheating" easier. The core problem with empathy is simply that it's an appeal to emotional decisions over reason.
The nyt article is pretty high intensity - walking alone (i speak as one who walks everywhere) doesn't get your heart rate racing unless you really put some effort into it, and certainly doesn't stress any muscle groups. Your average sedentary individual would not be able to complete the 7 minute workout. If they were signicantly overweight they would likely collapse 2 minutes into it.

The goal of this type of training is to yield the greatest amount of impact with the least amount of effort in the shortest amount of time.

Anybody who did the nyt 7 minute exercise at max intensity for a couple months is going to be in good shape. Do it everyday for 6 months and they will be in the 90th percentile of physical fitness in the United States for their age group.

Which I think is a pretty good return for 7 minutes out if your day with no equipment other than a chair.
