It's not just about recurrences. Although, It looks like this at the first glance. This book will give you mathematical mindset which you will be able to apply in practice (while working with algorithms).

Each chapter in the book is written in essay style, authors gave you very curious math pearls, and teach you how to think by using these examples.
I remember not a long ago, the same type of landing page, but this time for Apple's Swift courses, appeared the day after Apple announced Swift programming language on their event.

I guess people nowadays want to research their market, before even write some code.
This makes me wonder if you could map a building using existing 5ghz wifi n/ac signals.
I'm not exactly sure of the board culture here regarding unsubstantial comments but I'd like to thank you for taking the time to write all this out anyways. Same goes for everyone else who contributed.
Author here.

Using that logic you can reduce a whole heap of things down to just "thin wrappers".

Yes, LispKit is a wrapper around a C++/C browser library. But would you really want someone writing yet another browser implementation in 2014? It's just not good engineering to rewrite things such as that. They're complicated, filled with security edge cases and would take a substantial amount of time compared to "just" writing a wrapper library.

In reality, LispKit exposes the WebKit API through Lisp using a bunch of relatively idiomatic (if I do say so myself!) functions and macros. For the most part it seems as if Lispkit was built from the ground up in Lisp. It does not feel like a "thin wrapper".
There are also some very good books by Israel Gelfand, written for a high-school level. Titles are Algebra, Trigonometry, The Method of Coordinates, etc. All by Gelfand and one other author. Sort of unusual because they are basic books written by one of the greatest mathematicians of the 20th century.
Then what is your argument? That it's worthless because it's not written in pure Lisp? Look at the Closure browser, it's awful and incomplete. There just isn't enough manpower in the Lisp community to accomplish something such as that.
It's in a legal band for any use, but you are correct, the output power is 300-600 times too high to be unlicensed.
Got a chuckle out of me!
I came here to suggest the same thing. I started with real analysis but realized that I was lacking the mathematical maturity to understand things back to first principles. My suggestion is to start with learning how the foundations of mathematics were rebuilt starting from axiomatic principles in the last part of the 19th century and early 20th century.

The book How to Prove It helped me tremendously. Get a good book on abstract algebra. Maybe start with Herstein, then progress to Dummit and Foote and, maybe eventually, to Hungerford. This is the kind of math that will help you reason about data sets. It's foundational in mathematics and it also happens to be very applicable to computer science.

After that, you will have a strong basis for branching out to more specialized branches of mathematics that may have more relevance to the types of problems that you're solving.
That depends. Are we letting Mitch McConnell and Ted Cruz run it?
Construction of the reals is in an appendix at the back. He starts with ordered field axioms.

Frankly there's something about the presentation in "discrete math" books that I find much more confusing and difficult than Spivak, which is just talking logically about numbers and their properties.
>I have little interaction with Wikipedia other than editing it

Well... thanks for your effort!
I'd recommending piping it through a Heroku app. Just request the data from your app and have the app process the data. It's slightly less transparent, but it's a lighter footprint on the browser itself.
The intention was to stifle the competition in the moneymaking part of the business. IIRC at one point Real were like "name your price" for a license for the DRM technology, and were told it was not for sale.

That's so bad. Account management has always been abyssimal.

No account merging, no transfer of purchase is a part of it. I found the easiest way has always been to keep multiple accounts and switch accounts when switching stores.

But when I say "easiest" it's more like "less horrible than all the other way you can get screwed" and you still have to so many battles to fight to have your content where you want.
Pugh taught my ODEs course in college and basically turned it into a dynamical systems party. Great class, but I still don't know anything about ODEs. Really cool guy.
Frameworks upon frameworks upon frameworks, running in a platform-dependent embedded mobile browser, wrapped together with AppGyver-specific API thunks for accessing some native functionality in a non-standard way. There's tremendous impedance mismatch at every layer here.

I don't feel these deeply convoluted stacks are ever the right way to build a mobile app... Unless perhaps in the situation where you're already familiar with something like Angular and you know for sure that performance and look & feel won't be important criteria.
Here's the JavaScript behind it:
https://www.gstatic.com/recaptcha/api2/r20141202135649/recap...

It's hard to see what's sent over the wire (it's obfuscated), but the source gives you a good idea of what they're collecting. The biggie is the GA cookie which is running on over 10 million sites. Like any CAPTCHA, this is still breakable -- just load your actual cookies into Selenium or PhantomJS and replay your mouse movements. Of course, once you do that more than a couple times, you'll likely have to write a crawlers to generate fresh cookies. At that point, you may as well just break the visual CAPTCHA which is trivial anyway. Ie. You should still never use a CAPTCHA (http://www.onlineaspect.com/2010/07/02/why-you-should-never-...).
@ArkyBeagle Thank you for the book recommended!

@smtucker I'm also a math noob, and I'm a half way through Udacity's "College Algebra" (free) course:

An article on The Hollywood Reporter has some more information on this, including perspectives from sources elsewhere within the industry: http://www.hollywoodreporter.com/news/sony-hack-studio-secur...

"It's changing our business," says one producer of its impact on Hollywood. "From now on, money and time will be allocated by studios to deal with this full-time."

...as it should have been already, given how big and how valuable a target these companies are.
This is a coincidence, just yesterday i checked out Cordova, Ionic (on todo list, but the demo's on the APK's seem to slow :s), Supersonic seems quite interesting also (and a lot easier then Polymer)!

But what really interested me are the demos from Google (Namely Paper Elements as UI) with Polymer (it's like AngularJS, but it isn't): https://www.polymer-project.org/docs/elements/material.html

Fyi, an index of webcomponents for polymer is available on : http://customelements.io/

There's a designer tool for it: https://www.polymer-project.org/tools/designer/ , here's how to use it http://goo.gl/r8ovXN (it's a responsive maps application, with search input and speech input)
The range resolution would go from 8.5" to five yards if you changed the bandwidth to 30 MHz. Currently the radar could figure out the direction a person is facing to about 45 degrees. 5 yards would be good to find the orientation of a house.

Parabolic antennas are just horns with lenses. The bigger the parabola, the better the focus and the wider the bandwidth. A horn would be a few inches across, but a 700 MHz reflector would be a couple feet.

Not knowing anything about it did not stop every damn "news" channel from saying "oh North Korea did it" then added at the end "but there is no proof".

How can "news" call themselves news if all they do is speculate. Granted it wouldn't be entertaining if all they said was "Sony got hacked and we don't have any details" but that is why news is called news.

Every password dump, claim of responsibility for a hack, etc. I have ever seen has been on pastebin.

I suspect this is just because it'a a highly-visible, non-sketchy domain name that provides free, scalable hosting of text that can be used anonymously without much effort.
Yeah I was wondering about what's different between this and ionic. Looks like some of the elements are 'native' rather than html representations of native elements such as tabs and slide out menus are done with native elements for performance reasons.

I like ionic but this looks pretty good, its forked from ionic. Will give it a run on my next project

no, honey is fructose and glucose separate.

sugar is sucrose - glucose and fructose in a very high energy bond.

apart that honey has a lot of other stuff(bee saliva, pollen) which make the SPEED of absorbtion wayyyyyyyyyyyy different
AppGyver employee here – the part from Ionic we forked is the great CSS defaults, so it's more like "Ionic CSS + AngularJS + Cordova + AppGyver stuff". What we bring on top of the CSS framework is native navigation, native UI components, data etc.

sucrose is not same as fructose and glucose.

fruit and honey have a lot of other stuff which slows THE SPEED OF ABSORPTION into blood and does not spike insulin in a wild way like sugar.

try eating spoon of sugar and compare the feel with spoon of honey. it is obvious.
The way you phrase that, it sounds like you're saying there could be a machine that operates due to permanent magnets, but depletes them as it runs, so that eventually they're not magnetic anymore. That's an interesting proposition.. Is there any reason a machine like that could or couldn't exist?
If you really want to go back to first principles, try "Foundations of Analysis" by Edmund Landau. It builds the integers, fractions, Dedekind cuts, and the real and complex numbers from scratch.

It's totally rigorous and starts from, "the ability to read English and to think logically -- no high-school mathematics, and certainly no advanced mathematics."
Facts alone don't change behavior
Amen, less is more. I think certain programming languages and ecosystems just naturally attract these huge, convoluted stacks, and I don't necessarily mean JavaScript, but UI programming in general. This shit has all been tried before. If you're familiar with .NET, let's just think back to the atrocity that was / is .NET Webforms + .NET AJAX.

I think it's sad that certain people think that a frameworks like WPF or AngularJS are "great" or even "decent enough", it just shows you how abysmal the current state of UI programming really is.

This is definitely the fastest way to create polished native like hybrid apps for sure. I would not do any native code for iOS/Android unless it is some really resource demanding app (games for example). But for data driven apps, this is just sweet.
The Ionic fork is just the css (a small piece of what supersonic is).
Bravo to the Dutch authorities for using public information and a focus on public health to try and keep the public, and tourists, safe. I like this approach a lot more than throwing everyone in jail.

Yeah. I worked for a long time as a professional musician in an orchestra. I fucked up my hands from practising too much, so I switched career.

I can reliably hear a pitch difference of ~0.2hz at this site: http://tonometric.com/adaptivepitch/

and that is after 15 years in a symphony orchestra having my ears blasted by the brass and percussion section (with a demonstrated hearing impairment from my time in the orchestra).
Captchas can also be useful as a differentiator between free/paid plans, or to slow down users (see 4chan)
The "state sponsored" line was about a form a data recovery sabotage used. Seems an insider would have a similar desire to hide tracks. Blame the "mysterious outside forces" is always the kneejerk tho.
The big unique thing is the native UI and navigation – instead of running a single WebView and doing everything in the DOM, we actually shuffle around multiple WebViews by leveraging the native navigation controllers (and native UI elements like navigation bar).

This means that you can e.g. have your details view running in the device memory even when it's not visible. Then, when you click on a link on your index page, the details view animates into view using a hardware-accelerated, native transition. Same for tabs – switching between them is instant, since no DOM needs to be redrawn. It's a whole separate WebView being brought onto the screen.

Against the PDP-11, which the VAX directly descended from, but yes. Unix and C were written for the PDP series.
Can you get away with that in pre-ANSI C? I wouldn't be surprised.
Ionic has no runtime.. you have to use cordova/phonegap which sucks big time.
Supersonic has its own runtimes for iOS and Android that have much more features and are way faster... + they are compatible with Cordova/Phonegap plugins
So you're bellyaching about Wikipedia having $51 million in the bank and spending $684,000 on furniture (if true)?

Don't you realize how tiny those numbers are compared to the incredibly wasteful spending by any governmental agency at any level of government, or by any organization or company with monopoly status, or hell, just any really large company?

For something I use every single day for free (unless I choose to contribute), I think Wikipedia is astonishingly great value.

I think it would be great value even if it had the budget of, say, the US Department of Labor ($13 billion -- billion with a "B").

Why do you pick on Wikipedia when there are things 250 times worse?
No. it might be an issue. You can report it here https://forums.appgyver.com
The only browser you can run on iOS is the Mobile Safari, which is ok. Apple is slowly bringing in WKWebView which will be even better than Mobile Safari (there are still some issues apple has to crack though).

And when it comes to Android devices, AppGyver works with Intel and crosswalk is used to bring unified experience on all devices. Crosswalk is fork of the newest chromium codebase. Check out https://crosswalk-project.org/ for more information about this.

I am "bellyaching" about the call for donations when none are needed, and those that have been given in the past have not been used appropriately. I am also against government waste.
You'd think they would've learned a thing or two after they were made the hackers' pinata the last time around. Sony continues to come up as the poster-boy company for weak security.
So how would you do it any better? AngularJS and WPF are both great for their porpose.

How much longer would it take if they had to write Apache Cordova/Ionic from the start? How much longer would you create a website without Bootstrap or jQuery?
I used Fossil for a while, and I liked it a lot. But after using it with my team, and having to host it internally (something I didn't have the time to do properly being a startup), and programmers complaining about the conflict resolution process, we moved our projects over to git/GitHub. Honestly, I haven't looked back, even though I much preferred Fossil's simplicity.
If advertising wouldn't produce anything, it wouldn't exist. Your statement is quite common, but actually advertising performance is much more measurable than developer performance. Advertising is about to enable the right product to find its buyer. It is also financing the whole internet economy much more than the services the end-consumer think they use.
Around social media I won't comment. Probably many companies are trying to get a footprint there. Nowadays more and more people are expecting Twitter support for example. Nothing wrong with this, I expect controlling will know how to limit expenses in this area to a reasonnable amount.
Thanks for putting this question. I too hope to do this someday .. I am stuck with knowing what are the fundamental topics so that i can apply what i learn to as many domain as i see fit, with minimal learning of basic concepts.
I have unfortunately not made that much headway.

Supersonic is much more than a UI Framework, it is all of the best tools and components you need to develop hybrid mobile apps in a single place.
Anyone that has real world experience developing hybrid mobile apps knows the hassle and hundreds of different bits and pieces requires for development. It is time consuming and painful.
Supersonic is all about taking out the pain and complexity. It brings together all of the best pieces available instead of reinventing the well + it has some great innovations of its own.
You should try it now.

Fruit has small amounts of fiber that slightly slow absorption. Honey does not. It has the exact same effect as any other sugar. Rather than "feeling" it, try measuring it.
Feels like your are describing an enterprise app.

That's also the same kind of situations where you have to freeze the hardware and software versions to keep it working, and in 5 years you still have to keep iOS8 devices running around, like it was done with IE6 in the old days.

>And the bottom line is the dietary dos and do nots for diabetics just don't apply to healthy people.

Nobody said they did. So, why the angry long rant directed at me exactly?
If they did it on purpose it's even sillier. They may think that it would be cool to say they "got hacked by a state" especially if it's related to an upcoming movie about it, but to me it seems like amateur hour at Sony if they got hacked by North Korea, a country not exactly known for its advanced technology and high computer usage.
Thanks so much for your insightful post.

I was working through the first couple of chapters in Spivak's Calculus recently, and was struck by 1) what a great book it was, and 2) what a time commitment it would take to complete it properly! If I could choose a book to take to a tropical island for a year, Spivak might be it. But is it worth spending hundreds of hours working through Spivak and Pugh from the standpoint of developing a professional skill? For someone like OP already out of college and wanting to learn to think mathematically to apply it to programming/electronics, is working through these books as a basis to pursue further mathematical studies overkill? Or worth it?

So you're not using webview for the entire app? Does this mean that one could possibly implement the camera-feature of the facebook chat client? The one where the viewfinder occupies the lower 2/5ths of the screen (where the keyboard would go). I have an app-idea in my head that would benefit from this ;)
Sure, great. Honestly, I don't mind what companies want to do with contractors and contracting. I've been a contractor for a short time. If a big chunk of the 3x is business value created, great, go ahead.

My only actual point here is that rather than trying to tailor a visa just for the special needs of Silicon Valley start-ups, we should be tailoring high-skilled work-visa programs for letting the market decide what constitutes high-value work, viz: work that people will pay a lot for.
QR codes are:

*Available right now
*Widely adopted
*Vendor-independent
*Free to implement
*Very robust
*Visually distinct

A lot of "QR killers" considered that last point as a disadvantage, and tried to "solve" it by sacrificing robustness. They failed, and most of those codes are now invalid because they relied on a proprietary service.

I think it's actually a strength. You can probably train a monkey to scan a QR. Just point phone at funny square[1]. With this, most people won't even know it's there, so you'll basically need to have your phone out (but you can't even use your phone while scanning for codes, like you can with bluetooth beacons).

This an impressive technology, but it's not going to "replace" QR, and the potential usage scenarios in the article are a little far fetched.

Way to miss the point.

>I don't need to spell it out but $51m can only afford one year of operating costs.

False.

>If they cut all salary and all travel and all conferences they would last at most two years.

False. Salaries alone are $20 million. Awards are $6 million. $2 million for conferences.

>It turns out it does take millions of dollars to run an operation as large and as often visited as Wikipedia.

It doesn't. The cost of hosting has remained steady over the past few years at $2.5million, despite traffic rising. The vast majority of the increase of the use of funds is for staff, most of whom do not contribute to the content or product in any meaningful way.

>Maybe there's another reasonable explanation (outside golden chairs?)

I'd like to hear it.
I wonder how the comparison would be with Polymer (or Paper Elements) on page: http://www.appgyver.com/supersonic/comparison
