Wow, I'm just now seeing this news. Initially, I had that sinking feeling set in... I mean, like you, I have been impacted by his story, his games (not just the Wolfenstein/Doom/Quake franchises... I'm talking Commander Keen, boys and girls), his code, reading Masters of Doom, etc.

I can see my copy of Michael Abrash's Graphics Programming Black Book Special Edition sitting here, which was such a treat to read when it came out, because it has so many great chapters on the development of Quake and little stories about John's discoveries and thought processes throughout the development of the game.

But, then I thought... wait... this is a new beginning. I wrote about this previously, but, look for gaming to start heading in the direction of VR with technology like Oculus Rift. Also, with someone of the caliber of John Carmack involved (now totally focused on it because of the resignation announcement) with not only his passion and skill, but his ability to work with graphics hardware manufacturers and driver developers to effect change and garner the necessary support and backing, expect to see vibrant, compelling developments in this field.

In case you missed it, check this video out of John discussing some of his VR work. It is from E3 2012:

That momentary sinking feeling has faded away now... great things are ahead!

This is fantastic news.

I loved Id back in the day. When all it took for a game studio to be great was the most advanced code, Id was king! Then FPS games became more like movies, and Id became a bit like Michael Bay. They still pushed the technology forward, but almost everyone was making FPS's that had better plots, characters, etc.. The technologies Id licenses to other game studios are put to better use by them than in Id's own hands!

VR has been around for decades, but it has always sucked. Low resolution displays and poor head-tracking have historically been problems, but latency has long been a problem that trumped all others. Carmack and Oculus were already working on getting Rift's latency down to levels that would make VR a less nauseating experience for users.

This move just means Carmack is finding his work at Oculus more rewarding than at Id. That means we can probably expect great things from Oculus in the near future.

I think this check had been in the mail for a while. He is clearly far more excited these days about VR and where it can go. I'm sure he has more than enough money too to never have to worry about working again if he wanted.

I really wish him the best of luck, truly one of my favorite people in tech. I hope we still can get his annual keynotes, because they are great to listen to.

First Winamp, and now John Carmack leaves id. This has been a brutal week.

On one hand, it's exciting to see John working on VR tech. I really do hope we see something amazing out of it. But it still feels wrong, an id Software without Carmack. Hopefully they can continue on and reclaim some of their former glory as well, and let's hope Carmack keeps in the spotlight.

It's a little sad news but exciting as well. I'd rather see John's mind helping push VR/AR and 'cheaper/nimbler/entrepeneurial/hacker-maker/DIY' aerospace forward than churning out yet another 3D FPS game. We have tons of great games/engines of that type already to choose from, and lots of great people continuing to work in that space.

What a strange move. Maybe he wasn't spending enough time at iD and was forced to leave?

You'd think his having a leg in gaming and a leg in VR would create a wonderful synergy. Knowing all the in's and out of both worlds he could have insured great integration of Doom 4 with the Oculus rift - making sure iD was on the technological forefront while the Oculus would have a great demo from day 1.

(see the Leap Motion for an example of what happens when you don't have a good demo day 1)

In the early days of PC gaming John Carmack was a genius, and Quake 3 was his masterpiece. I guess he is still a genius, but from an outsider's perspective the advancements he has made since then don't seem to changed the world in the same way.

Graphics get prettier, but gameplay stays the same, or even gets worse because the prettier graphics require higher budgets which require lowest-common-denominator appeal to recoup.

So it's good that he is trying something truly new now, where he has a chance to make a difference again.

This sounds important, but I'm at a loss as to its significance.

What was Clapper v Amnesty?

It sounds like Solicitor General Verrilli made a lie of omission in the court. Is that considered a lie under oath?

What obligation does Solicitor General Verrilli have to the three Senators to answer their questions? What consequences might he face if he choose to ignore the letter?

Realistically, what could this mean for the original Clapper v Amnesty case, and how might it affect the public in general?

I know the words "ethics" and "lawyers" don't generally enters people's minds at the same time, but the model rules of ethics for lawyers take this sort of thing seriously. If the Senators show that some lawyers did indeed lie to the Supreme Court, the Court itself could take action on those attorneys' licenses. It's also a lawyer's duty to report if they are aware of another attorney's violations of ethical rules.

I know it's doubtful, but one can hope.

Someone just made a $147,239,214 Bitcoin transfer blockchain.info

tokenadult 3 hours ago 1 reply      
If this was an actual transfer of ownership of Bitcoin at all near that value, this would trigger money-transfer reporting requirements under the laws of most countries,[1] especially if this was an international transfer of ownership. I see that all the other comments here are speculating about what exactly happened here, and one astute comment before this one pointed out that the actual owner of the Bitcoin may still be the same individual person both before and after this blockchain transfer. It will be interesting to see how the regulatory environment keeps up with the implementation of Bitcoin, which so far is a very tiny percentage of the world economy.

There were also statements in some previous comments that this transfer was made for free. It is true enough that a Bitcoin transfer doesn't inherently incur a processing charge from a merchant payment processor, but as merchants learned back in the Middle Ages when charging interest was formally illegal, the price of a transaction can hide financing and processing costs. We don't know what was agreed with whom by whom to make this transfer happen. The transfer may have occurred at a higher than list price for something that was bought, to make up for the ongoing inconvenience of receiving a payment using the new Bitcoin payment mechanism.

[1] One example, among many: http://www.consumerfinance.gov/remittances-transfer-rule-ame...

Consider this: They paid $0.00 for the transfer of $150 million dollars.

A direct (i.e. not based on third party credit, regulations, etc.) transfer of wealth of this magnitude between two entities usually consists of a heavily guarded, insured, physical shipment of cash or gold. Depending how safely you want to make the transfer, and how far the entities are on the globe, it can cost hundreds of thousands to millions of dollars.

Bitcoin has real value. It solves problems on an incredible scale. I wish I realized this months ago.

Hardly. If you tried to sell 195,000 coins you'd wipe out all the exchanges and cause a crash.

Talking numbers, you could sell them all on BTC-E right now, bagging you just $7M, and take the price down to ~$36. You can spread that around the exchanges of course, if you're quick, but you're still nowhere near $147M at current market depth.

Turntable.fm shutting down - new "Turntable Live" introduced turntable.fm

tks2103 19 minutes ago 1 reply      
Turntable dunked all other music streaming sites in playlist quality for the simple reason that the intelligence behind song selection resided in humans rather than an algorithm.

It was a specific application of the general idea that social recommendations are more powerful than algorithmic recommendations. I don't know how valid the general idea is, but when it came to Turntable, it worked. People search the space of musical works much more effectively than algorithms.

And then Turntable did nothing with that power. They had high quality playlists being minted by the thousands on a daily basis, and I could not access any of them.

At least for a time, they were focused on live engagement. Unfortunately, it's just too hard to grow a music streaming product that demands each listener be present to click a button for every song. I loved the service, but I also have a job. I cannot be on the site all day long. At the risk of being presumptuous, I would guess that the product leaders were blinded by their devotion to live engagement.

Focusing instead on their brilliant, yet simple, solution to the problem of "What song should go on next?" would have been the right call. But they did not walk this path.

As for their new product, which predictably focuses more intently on the live engagement aspect, I am unconvinced. Turntable Live provides a subset of the functionality that Twitch.tv does, with less reach.

Best of luck to them. No doubt, they are an extremely talented team.

And I'm really, really going to miss Turntable. Kickass idea. (yeah yeah plug.dj, whatever)

I don't see this move being popular. They are basically demoting the users from both consumers and curators to just consumers of the music. What made turnable.fm awesome was that it was people like yourself deciding on what everyone wanted to listen; if people didn't like the choices, someone else could be selected. Now that control is out of the equation. The artists are selecting what everyone wants to hear, they are choosing based on what they want you to hear. Don't like the music? All you can do about it now is leave the room. Only time will tell if this is what brings turnable.fm into the spotlight, or sink it down into the depths.

Actually believe this would be a good plan. I listen to live music in Second Life (Don't laugh) and I've found live music works well when streamed live both audio only and video.

For musicians, its great to perform live for people but having to tour and go from gig to gig, lugging equipment around, and most of the time only being paid beer money and travel expenses.

Being able to perform for an audience but not having to leave your doorstep saves you both time and money. You can reach more people worldwide than you can in a small pub holding fifty to a hundred.

I understand people love turntable.fm but the labels have pretty much killed innovation by the licensing so to me it isn't a surprising that streaming companies are having problems.

Maybe the new turntable.fm can be the Twitch.TV of the live music world. Who knows but anything is possible!

johnthealy3 1 hour ago 0 replies      
As much as I loved the concept of turntable, it was always a music service for me rather than the interactive experience they intended. The best part about it was that other users, not bots or radio station managers, determined the playlist and therefore led to new and interesting tracks. However, the interface didn't really support my usage and hearing familiar tracks became more and more rare as the rooms became more established.

Their decision to focus on virtual events makes sense from a monetization standpoint, and I couldn't agree more with their approach. I do think there's a sweetspot to be had for user-generated radio, as Pandora is too repetitive while Turntable was not repetitive enough.

There's also the classic DIY whiteboard recipe for those of us who are very cheap/not yet funded:

Get a 4x8 sheet of shower board from Home Depot. It's basically just a thin piece of melamine, and should be like 8 bucks.

Get a 4x8 sheet of really low grade 3/8" or 1/2" cedar chipboard (like that used in flooring), again maybe 3-4 bucks.

Glue the former onto the latter with Liquid Nails, probably 2-3 bucks a tube.

Works great, erases, and when it finally gets too gross to use (in about a year), you replace it for another fifteen bucks.

Reading more about this match and Magnus in general, I learned of a measure termed "Nettlesomeness" which has been used to measure which players do the most to make their opponents to make mistakes. Magnus, with his highly creative style of play and unexpected moves, not surprisingly ranks the highest in this measure.

He seems to have this remarkable gift of making moves which aren't just strong, they get inside his opponent's head and cause them to either overthink/break down. I'm interested in the technical details behind this metric. Has anyone heard of it before?

Regardless, congrats Magnus. You are truly a generational talent, and I'm excited to see what your win will do for the game.

Congrats Magnus Carlsen! You finally unseated our beloved Vishwanathan Anand and made the beautiful game even more beautiful.

Allow me to go on a tangent to let me tell my personal story with chess. I began playing at age 7 when my elder brother borrowed a chess board from a friend. It was a nice break from the physical altercations between us(read mat fights). My maternal grand ma called it "Satan's Game". And my mother toed the line. Why? I don't know the exact reason, but I guess it was an amazing time sink. Or maybe they both had watched this Hindi movie by Satyajit Ray: The Chess Players(http://www.imdb.com/title/tt0076696/). When the game s between my brother and me became violent(You moved it when I was off to the toilet...) it was banned from our home. But we didn't give up. Our summers were spent playing chess in a nearby mango orchard or the graveyard a mile away. The chess board made out of paper with plastic pieces was the only "toy" we never broke. Those were the best days of my life. And it's still safe 20 years later. With every piece intact. What a game.

I am Norwegian and fucking proud of it right now, due to Magnus Carlsen.

He comes from a Nation consisting of 5 mill. people, compared to Anand's billion people.

This is probably the greatest sports achievement our country will ever make, as there are really no comparable sports achievements in the world, not now, anyway.

IMHO: They should knight him the second he gets of the plane when he returns home. Because no other Norwegian has ever accomplished anything close to this, with regards to bring honour to our nation.

Gratuler Magnus!

After spending the last 18-months immersed in the professional StarCraft 2 scene, I can totally appreciate a lot of the meta-stuff around Chess now. I always enjoyed Chess, and was not too bad at it (compared to those around me, certainly nowhere near even an amateur-pro!), but for some reason SC2 "clicks" better for me (I think being addicted to Brood War while spending 6 months in South Korea probably has something to do with it).

The discussion of "mind games" {"nettlesomeness" here) is something that SC2 has an obsession with, and certainly can play a massive part in pro tournaments, and I'd never considered it applying to chess... but now that I think about it, everything in SC2's meta really came from Chess to begin with, only applied in real-time with 300+ actions per minute and hundreds of pieces with few illegal moves. And yet I struggle more with grokking the advanced strategies of Chess than I do for StarCraft!

<blasphemy alert> Does anyone know some good alternatives to chess, as a game that mixes deep thought and aesthetic variety? I tried Go, but found it somewhat boring compared to chess, because of its uniformity (which, on the other hand, has the advantage of beautiful simplicity and symmetry.) On another note: it is unfortunate, in my opinion, that chess has a special standing among board games. I would love to see some more variety in world-class intellectual matches, similar to what exists in physical sports. Something like a "board game Olympics".

Edit: Thank you for all the useful replies! In reply to some of you, I am a complete beginner at Go. Maybe the word 'boring' was not carefully chosen. As a programmer, I should have known better - that things may seem boring (tiresome?) until you become more fluent with them. I should certainly give Go another shot...

Let's try this advice. Say, we're solving Hanoi Towers [1]. So, we're going to have rods, and disks, and rods are going to have the number of disks on them, and disks are going to have size, and probably a reference to the disk underneath, and a reference to the disk on top, and maybe also weight and color... and by the end of the day instead of a 10-line snippet [2] we're going to have Enterprise Java Beans.

No, it doesn't mean that OOP is awful - it just means that this particular way of modeling a problem is a recipe for over-engineering.

Start with the simplest thing that works. That thing will probably be just a function. Grow it from there. If it gets too big, split it. If you find that you pass the same 12 parameters to a bunch of functions - factor out a class. If you do the same thing in a bunch of classes - abstract it out. Keep it DRY [3]. Keep it SOLID [4]. Rinse and repeat. This way you end up with a useful class hierarchy - and OOP won't be awful.

It is utterly ill-advised. Software design is about abstraction, to make code modular, flexible, and extensible. It doesn't matter it is OOP or FP. Both approaches have their own advantages and limitations.

The dogmatic answer is misleading. It might be ok to introduce OOP to new programmers, to open a door for programmers who are only familiar with procedural programming. For any experienced programmers, if they don't believe in this dogma, I have to say this is not a right career for them.

I think this seems a little too existential. What is more important, that you classified the right nouns and verbs in your Paws and Dogs, or that your code works?

In my view OOP is all about sane interfaces between components. In your internal code however, you should feel free to let your implementation details and data structures drive the flow, and not con yourself into writing OO spaghetti, that type of code written by inexperienced types who "heard somewhere to use classes" and can only think in classes, and the abstraction serves to obfuscate rather than clarify.

1. First, write some use case scenarios/specs in order to get a better understanding of the problem (for libraries this is README.md, for user-facing programs its the user's problem and the solution's workflow)

2. Write the code the way you would ideally want it to work, top-down. Imagine that you're in fantasy land. Don't worry about it being wrong or impossible to do that way. That will be corrected later.

Use classes to express blueprints for tiny worker machines that work on data, not the data itself. Use classes to simulate entities.

A user is not the user's personal information - thats a data structure. A user class makes sense in a testing framework where you want to simulate the process of a user visiting a website.

A button is a worker machine that can detect a set of inputs and call attached functions. A list is a worker machine that can keep items and update the screen based on its scroll position. A stream is a worker that can be customized to process incomming data packets in a certain way, and its output can be connected to another stream.

Think of classes as tiny single-purpose computers or simulators.

3. Express details about the desired outputs of that top-down code as tests.

4. This is a good time to write all the data structures to represent your data. You can use relational modeling here even if you're not using a relational database (or any kind of database), but you can also use pointers/references instead of foreign keys.

Model the data structures for all data (including computed data), not just input or stored data.

You can also do this before step 2. but in that case you will be tempted to write your code to operate directly on the lowest level data structures, instead of making it look clean and simple.

5. Try to make the tests pass.

6. If its impossible to implement or you realize its not a good idea to implement it that way, tweak the test a bit then change your code and data structures as you get a better understanding of the problem.

7. Once you're satisfied with the test, you can stop.

8. If the future of the program requires you to adapt it, keep working like that over the existing code. The tests give you some reasonable assurance that it still solves the old variant of the problem, while new tests will ensure that the code sanely solves newer problems too.

Actually, only #1 and #2, "simple statements about what these objects will be doing", are relevant. The 'nouns' points are misleading at best. OO is all about behavior ('services'), not about data. A class doesn't encapsulate data, it encapsulates state. That's a big difference that many OO aficionados don't realize.Another source of confusion is that in some OO languages 'everything' has to be a class. A Java class in many cases isn't a class in terms of OO. Java Beans e.g. certainly are not OO classes.

It's interesting to note that the question was "how to design a class", which to me sounds like a question about static structure, e.g. what data members and methods will the class have. Most of the discussion on this and the SO page mixes in OOD, OOP with the original question and then throws in some inappropriate OO vs. FP tangents.

It's important to remember that there's a lot of, for lack of a better word, "class-oriented design" which typically tries to model the static structure of the physical world or some artefacts of the programming environment.

In a completely separate world there's what I would call OO design and programming which is more concerned about the interaction of actual objects aka. instances of classes. Coming from the statically typed world the distinction is often unclear but for the original Smalltalkers and other OO purists object orientation was never about classes.

This is a major reason why the practice of welding, and soldering, is so complicated.

A lot of what makes welding and soldering complicated is the need to remove, or avoid creation of, the oxide layers that inevitably form on the surfaces of metals. More so, these oxides form faster at higher temperatures. That's why solder wire and stick welding electrodes have flux cores or coatings, why MIG/TIG welding uses a shielding gas, and so on.

I like this, but it seems too cryptic for a true novice to actually learn from, especially if they've never been exposed to Lisp syntax. Who is the intended audience?

I see that it's something of a port of the Clojure Koans, has there been much feedback on that as to whether people are able to truly learn the language this way? I'm intrigued by new methods of instruction, but this seems like it would be a very frustrating trial-and-error game to a beginner, as there is virtually zero actual teaching. We're supposed to be making programming more accessible, not less. It seems like this kind of thing ends up as a fun toy/experiment for people who already know most of it.

This goes from easy/novice up to advanced level in a short amount of time. I did some koans until I arrived at functions/9 which is:

I found this one to be not so trivial, granted I'm still a novice clojure user, but I still think that it went up rather steeply here.

I think if they really want to introduce new people to ClojureScript, then the koans need a friendly help system and the ability to show the solution and have it explained to you.

It should also have a short introduction in Lisp that explains prefix notation / s-expressions. I think that would make things a lot easier.

I want to quickly distinguish our Hybrid Cloud offering from our Private Cloud offering since I thinks this may keep coming up in this thread.

In the Hybrid Cloud offering (this is our 'classic' or previous offering that's been available for quite some time) we don't store any data on our servers. However, because some communication does happen with our servers (e.g. for registration), we heard from businesses and enterprises that they would like a completely on-prem solution to guarantee no data goes to our servers.

This completely on-prem solution is the AeroFS Private Cloud. It's a virtual machine that is packaged as either an OpenStack image or an OVF/OVA file (supporting VMWare/Virtualbox), and in this VM absolutely no communication happens with our servers, period.

(and you can easily verify that)

Plus the files are only synced within your own computers so security/privacy is much better than uploading all your files to a public service like Dropbox.

The only negative as compared to Dropbox is that their client is not as efficient (it's Java based and takes a bit more resources than Dropbox).

This is pretty cool. Although, I'm having trouble clicking on the bonuses and don't see my score. I must be overlooking something and cba to decipher how this works at this hour.

Edit: Managed to make it the whole way through by leaving the ship in the bottom left. And then when the bonuses kept flying by uncontested because the game was "over", I was able to click on them after a few tries. The issue must have been that the cursor wasn't where I thought it was. Still very cool!

This really illustrates the true power of the web. No construct has a stable definition. If we can't or don't want to use JS to write algorithms, just add new features to CSS until it has the ability. Nobody needs a reliable format to write static documents. We need to keep extending amending extending amending extending amending (while trying to be backwards compatible)!

See: http://www.forbes.com/sites/leonardburman/2012/03/14/raising....

I don't think the minimum wage has been a great success anywhere it's been implemented, so I'm a bit surprised Germany would adopt it now instead of trying something more forward-looking. The conservatives in Germany could have preempted this I think by proposing some sort of minimum income like in Switzerland.

The last time this address was touched was 2009, and has an even 8,000 coins (back in the day, this only amounted to 320 mined blocks. You could do that in what?... a few hours/half days?[1]) The owner probably ran his system for a few hours, collected 8000 coins, thought it was a ridiculous concept and deleted everything from his system.

Just my $0.02:

OpenVPN has a built-in 2-factor authentication based on the X509 certificates: you need to have a valid certificate together with a valid password to connect to the VPN service. SMS/phone based authentication does not add another factor since it is also a "what you have" type of authentication (i.e. your laptop can be stolen in exactly the same time as your phone is stolen). Of course, X509 certificates work the best in the enterprise environment but that's the OpenVPN target market anyway.

I'm all for the market in most instances, but I really hope Internet access starts to be treated like a utility in the United States. It is approaching the necessity of electricity a century ago (or water, gas, roadways, etc.) The market had zero incentive to invest so heavily in these utilities for such a drawn out return before the government financed the basic infrastructure. I know the analogy isn't perfect for a few reasons, but imagine where we would be if all these other necessities were privatized?

As an Aggie and former Bryan / College Station resident (of 15 years), it's fantastic to see them taking a lead on this.

BCS has always been pretty good for high speed internet (I had 2Mbps cable in 1999), but the price disparity between residential and business is insane, and speed increases have stalled somewhat in recent years. Suddenlink is pretty good, but that area has been the target of rather frequent cable company acquisitions and mergers (TCA -> Cox -> Suddenlink just while I was there), so it's not a foregone conclusion that things will stay "ok".

I love living in SF, but I have to admit I kind of like the idea that my "little Texas town" will probably get gigabit and a sensible fiber infrastructure long before SF or most parts of Silicon Valley will.

"The old model was 'everybody has to have service,' which is where cable and telephone came from," Smith said. "This is a model that says, 'we can be patient while demand builds.' We'd like to see some of our most disadvantaged served, but we're not starting out with 'everybody must get service immediately.'"

My understanding is that Chattanooga's gigabit service was rolled out as quickly as they could as limited by funding to everyone within the service area. My understanding is that they are the only city in the US with such complete gigabit coverage.

I've read that they are now selling consulting services to other communities looking to do gigabit rollouts. I'd like to know what their take is on that philosophy since it seems to be the opposite of what they did and they seem to be significantly exceeding revenue targets.

* Bonded T1 / T3 ... insanely expensive.

Time warner business class moved in with fiber to the building and now we have:

* cable modem over coax muxed into fiber switch @ roughly $300/month for consumer-level speeds (30/5 megabit). which is what we use right now.

* Fiber to fiber (ethernet switch on customer premises):

10/10 megabit starting @ $1300/month (worse than EoC above)

40/40 megabit $2400/month

1gbps/1gbps for $14,000/month (yes $14 THOUSAND/month.

we pay $400/month at the datacenter for each of our 1gbit/1gbit links w/ a 100 megabit commitment.

It seems that with every passing day, another prominent institution or business starts accepting Bitcoin for payment, Virgin Galactic being the latest example. In just a few years, Bitcoin has gone from experiment to global phenomenon.

I wouldn't be surprised if in coming years at least some bitcoin users start measuring their wealth in bitcoins, and therefore also evaluating exchange rates, not in terms of how many US dollars, euros, etc. they can buy with a bitcoin, but the other way around: what is the cost, in bitcoins, of a single dollar, euro, etc.?

Looking at exchange rates in this manner changes people's perspective on volatility, which is always a relative measure. For example, since the beginning of this year, the price of a US dollar has declined by more than 98%, from BTC 0.074 to just over BTC 0.001, which makes the dollar look extremely volatile!

--

PS. I'm NOT saying the dollar is extremely volatile! I'm also NOT saying that Bitcoin is more stable! What I'm saying is that if and as Bitcoin adopters start measuring their wealth in bitcoins, their perspective on what is and isn't volatile will change, as demonstrated by my example.

Listen -- I know there's a lot of negativity on HN and I try not to add to it. But seeing mobile web succeed is something I'm pretty passionate about.

I played with the left nav example and it doesn't use inertia. This is one of the most ubiquitous interactions on mobile apps so it's probably one of the most important to get right. And while it's good by mobile web standards, the lack of inertia makes it feel completely and obviously wrong if you're comparing to native apps.

The lack of inertia is indicative of either not setting the bar high enough or not having the technical chops to implement it.

The reason this is a big deal is because mobile web's reputation is to cut corners like this and get 80% of the way there and then give up. That's why native is kicking mobile web's ass.

The worst part about this is the web can do a lot of this (for example, see the leftnav I built here http://petehunt.github.io/react-touch/), it's just that very few teams are doing it right (Sencha is one team doing it right). So the reason this post upsets me is because they call themselves a premier way to build native-like apps with web technologies and then just further the stereotype that web technologies can't compete. It really bugs me.

First of all, thanks for this @yesiamhuman, I came across it a few days ago just when I was despairing of finding something with the right look and feel (somebody mentioned it in an earlier HN item about a curated list of CSS frameworks). It looks like it's exactly what I need.

For the project I have in mind, the client wants an HTML5 web app, not an App Store delivered container. On the docs, you state:

"Since mobile browsers often exhibit issues while in browsing mode that don't show while running under a "wrapped" native app, we recommend running all Ionic examples in a Desktop browser, PhoneGap or another native wrapper."

Can you elaborate on this a bit? What issues am I likely to see if I just deliver my project as an offline capable single page web app?

I'm building a hybrid app right now. I can't see Angular and all its magic being a good fit. The provided browser controls in smart devices have horrible performance and are often several releases behind. Most are deceived thinking that a hybrid app that works well in a desktop browser will perform as well on smart devices. You will be disappointed. FWIW, I settled on Intel's App Framework after trying several popular frameworks.

As a side note, I'm surprised by how poor hybrid apps perform on Android. You would think Google of all companies would be pushing browser based technologies further.

It probably can't, depending on your definition of _serious_, but for 90% of the apps being built, this is perfectly suitable.

Regarding the app store, I see now reason why this wouldn't pass Apple critique -- they've been accepting Cordova-based applications often and for some time now.

As for what it offers, cross-platform publishing is a pretty big win for a bevy of developers that don't see the point in writing separate native apps for applications where native performance isn't terribly necessary.

My experience with Appgyver Steroids has been impressive. Performance is very good. Whether or not it could have been faster written natively vs. being compiled to native code is not substantially worth considering -- it's fast enough, by a large margin.

How does Ionic relate to different screen sizes, orientations and resolutions? Would responsive layouts be viable or is that out of the scope? The way I see it now is that it is targeted at phones and not so much at tablets.

BTW, the word 'which' is in the wrong place on the components page: "The advantage here is that the devices Ionic which supports, all support flexbox."

BTW2: in the Getting Started guide, chapters 4 and 5 have no link to the next chapter at the bottom.

I actually had one of these and I won't do another one either.

Here's the gist of how it went down:

1) first part was the "personality" interview. Two "HR" people blew smoke up my ass for about 30 minutes about how awesome my site and my work was, then asked me to do a "code challenge". I agreed - I mean, how bad could it be?

2) The code challenge. I was given a PSD with a straight forward design. Asked to code it, make sure it worked in legacy browsers, publish on a server and show them the code on GitHub

3) Passed and then was asked to come back and explain some of my coding decisions. I was told this was more for show and I was already in effect hired, I just had to pass this last hurdle. It turned out to be a very confrontational, inquisition type of an interview. Not at all the type of laid back code review I'm used it.

I got pretty frustrated by the two "Senior" devs who seemed to take great pride in tearing my code and my decisions apart. After my first heated exchange with one of the devs, I actually asked them how many of the sites listed in the gallery on their site they actually tested and validated the code on. They said "All of them, why do you ask?" I told them I actually ran all of their sites through the W3C validation site and none of them passed. Every single one had over 60 errors on it. I basically said, "If standards are so important to you, then why are you holding people who don't even work for your company to a higher standard than those who actually do?"

There was a long silence and then I finally spoke up and said, "Clearly, this company has its priorities in the wrong order. Thank you for time, but I'm not interested." and got up and walked out.

I got several worried calls from the company recruiter, but by then I was so pissed at how much of my time they had wasted, and vowed never to do something like it again.

Many years ago (wow...almost 10 now...I'm so old...) I was given a phone screen and at the end of the screen I was given a question to code a solution to and email it in. Since this was for a job across the country, I figure what the hell.

The problem was -A man has to get a fox, a chicken, and a sack of corn across a river.He has a rowboat, and it can only carry him and one other thing.If the fox and the chicken are left together, the fox will eat the chicken.If the chicken and the corn is left together, the chicken will eat the corn.Write a program that will help the man make the correct decision and explain the operational complexity.

I was given an hour to come up with a solution. I worked on it about half-an-hour coming up with the algorithm. And then for some reason my brain keyed in on the "write a program" part of the question. So I wrote the following in C++ (from memory so may not be exact) -

  int main(int argc, char** argv) {      std::cout           << "Man takes chicken, leaves fox and corn, and returns" << std::endl          << "Man takes fox, leaves corn, and returns with chicken" << std::endl          << "Man leaves chicken and takes corn, leaves corn with fox, and returns" << std::endl          << "Man takes chicken back across" << std::endl;      return 0;  }
It was a program that would tell the man the correct way to get everything across the river.

Must have been an OK answer because I got flown up and ended up working for them for 4 years (before a series of bad jobs that have finally lead back to something good).

Sigh - yet another hiring process complaint post. As an employer hopefully I can shed some light here.

a) If you are trying to hire 5 engineers, say, you need to talk to ~25 candidates at least. It's a competitive market. b) If you aim to talk to 25 candidates in a short period of time, you need to have SOME standard way to evaluate candidates if you don't want to just throw darts on the board. Being sloppy with process is bad for companies and the engineers and a waste of everyone's time. c) In order to create a standard process, you have a very limited # of options to work from. I've seen comments like "do a co-working day to get a real sense" or "do a contract and see them work with you daily" positioned as realistic options. They are not. If an engineer has an existing full-time job they don't have the time to do co-working days or contracts. d) The other options are 1) whiteboard interviews 2) coding challenges 3) some combination thereof. e) Lots of candidates hate whiteboard interviews. Lots of candidates hate coding challenges too. Neither is a perfect system but it's better than doing nothing or asking for co-working time. f) We use coding challenges at the top end but we time-box it to 3 hours. If someone asked us to pay for the time, we would happily do so. g) Our coding challenges have 3 different problems so candidates can pick whichever aligns best to skills. One problem is JavaScript-heavy and 2 others are Ruby/Rails-heavy. h) Several engineers on the team solved the coding challenges on a timed basis before we put them out to candidates. Doing otherwise would be stupid/unfair. i) In the few cases where we've been able to do 1-2 co-working days, we have offered to pay for the candidate's time. Not full freight consulting dollars but something that indicates our seriousness. j) In this case, the OP got caught by a dumb coding challenge to build a full website. But the headline paints with a broad brush because coding challenges by themselves are not evil. They are a tool that can be used well or poorly. That's all.

Every time this comes up, I find it quite depressing how everyone becomes so self-centered. Half the comments here are along the lines of: I'm good at X, but bad at Y, so X is a better way to judge programmers than Y and if you do Y, your process is broken because I'm awesome despite being bad at Y.

Another small fraction of the comments are: I don't care if you can't do X despite being good or won't do Y because it's a big hassle - the bug is a feature and it filters out people who are not into our instasnapsocialmobileresponsiveapp. Get real guys, no one's that into you, some people are just desperate. Pretending that you're some prestigious company where everyone wants to work doesn't make it so - you have to earn it and if you get there, you won't have to pretend because you'd get so many resumes that you'll be forced come up with a quick way to be selective.

The secret to hiring is just like what pg said about the secret to VC investing - get better at distinguishing good programmers from bad ones so that you don't need to waste so much of everyone's time to make a decision. Being indecisive, after being clearly presented with enough information is a sign of incompetence.

You have no idea how the "challenge" was completed. A candidate could have rent-a-coder-ed the project, refactored it a bit, and slapped their name on it.

Sure, if you ask no follow-up questions after the challenge is completed. However, with a few well-placed questions about the implementation and some inspection of the code, it'll be quite clear whether you're talking to the author or not.

We once gave a (non-web-dev) programming "challenge" (I thought it was a joke/insult given the candidate's claimed experience) to a senior dev candidate. Mind you, this was on-site. I even tested it by putting our newly hired grad to the test and he aced it within 20 minutes. We gave the candidate an hour to complete it (and added a 30 minute extension when he was struggling).

The challenge involved developing something against an SDK (interacting with a camera) and we gave him internet access and the SDK examples to work off of. In the end, he produced something not quite what we were asking, but he was sure to claim it as his work. Although it wasn't ideal, I was prepared to say that he "passed" the assignment, because he was close and I was sympathetic to factors of stress and nervousness.

As he was toured around the facility, I inspected the code and saw that he was completely passing off one of the SDK examples as his own work (diffs showed only two variable names had been changed). The reason his code didn't quite do what we wanted, is that he wasn't even able to tweak the SDK example to do what we asked. He was a complete fraud and never mind technical ability, we couldn't have dishonesty like that on the team.

Before that interview I thought those kind of challenges were a joke, but after this I saw their value. Of course, their value depends highly on how their are implemented and targeted, but dismiss their usefulness at your own peril.

Even "small" programming assignments take a lot of time. Several years ago, I applied for a job as a developer for a financial trading system. The take-home assignment was to build a small trading system that received buy and sell orders from the command line, and executed trades when the price matched. The input was just: buy/sell, price and number of shares.

This functionality is pretty simple, but it still took many hours to code. My feeling was that they thought it would perhaps take an hour to do. It was fun and interesting to do, but it took much longer than I thought. I think the companies giving the challenges should have their own engineers do the task, so they get a good handle on how much they are asking from the applicant. And of course it also depends on if it is a buyer's or seller's market (jobwise that is, not in terms of my "trading" system). If there is a lot of competition for developers, maybe they should give too big projects.

While I agree that the request to build, deploy and open source the code of a website is a bit too much, I think you are exaggerating a little bit on the why's you wouldn't do it.

"I'm not equipped to do your challenge" - really?

"Engineers aren't different" - again, really?

Rhetorical question: you don't want the job, do you?

I am not sure if the issue is with the hiring process, or with the candidates' ego here. Candidates. Plural. As the article's author doesn't seem to be the only one.

Apparently there is a lot of people that believe they are rockstars and they don't need the job, the job needs them.Challenges like this help to figure out non technical skills as well, like: how committed a candidate is; how much he wants that job.

I'd rather hire a junior that is committed than a senior that is not.

The worst thing about code-challenges, is they never give feed back.

We're sorry, but what you produced is not good enough. We're not going to tell you what you missed.

At least technology tells you what you missed. If you have a standard, have it documented so that I'm not firing a bullet into the dark. Chances are I'm just as good as you; but you won't know because I haven't seen your coding style. You're on my project, you code like me. I'm on yours, you better believe I'll code like you.

And then there is the times they like to dismiss you for it but have some other reason and use it as a cover. So you worry about your code not being perfect and you develop a ritual to validate yourself before it goes through a compiler. Yep, I write my code three(avg) times now. 10 lines, over and over until it's a effing poem. It's called ocd.

Coding challenges, pfft, worthless. There is only one company that I did a coding challenge for in the past year and it's because they were really awesome people. - I'm here to make a product and work with a team. I'm not here to explain shit to you just so you can tell me to look up the documentation. If I take the time to explain my code to you, you better well explain why you think something is better rather then telling me to google it.

fufff, I needed that.

Building a full production grade website seems extreme, but giving a prebuilt website to a front end candidate and asking them to add a few simple pages or features is basically fizzbuzz type vetting. I also like it when coding "challenges" are timeboxed to say 1-2 hours. This keeps the time expectations reasonable for both the interviewer who has to read a bunch of candidates' challenges and the interviewee who has to do them for (potentially) a bunch of gigs.

The type of coding challenge a company asks (interview questions also) can be one of the most important data points to use to judge a company's culture...

I understand the point the author's trying to make.

For me, personally, this would be the better choice to judge my skills - and probably would lead to better chances for me to get the job. I suck at these braindead trick questions that are considered 'clever'. I'm not comfortable around a whiteboard only, being grilled by one or more other people while thinking.

I'm not slow, not really anyway. But I'm faster and better the more I know about the stuff at hand. I'll be good on the job, I'll suck solving math puzzles that some guy just read about in a book that ranks high on Amazon's list of code puzzle collections..

So - I'm glad that there's both. The author obviously would've preferred to show his skills live, in a discussion. This guy here would be happy to hand you a (small, mind you - I agree with the time-sink argument) finished project and discuss _that_ afterwards.

On the other hand, as someone currently looking for my first dev job, I'd /much/ rather have a take home code challenge, where I can work at my usual pace, with my usual tools, without stress than have to do a code challenge while someone hovers over my shoulder. The take homes have been time intensive - I would say the average one has taken about 15 hours to do, but I feel they much better reflect my ability to code than real time nervous coding.

If you use a coding challenge as part of your hiring process, please take the time to give feedback to candidates.

I recently completed a code challenge, and I was told by the recruiter that there were "problems with it," but he didn't get into any specifics because he was just passing on the message, and no one else has called either. I look at it as a dodged bullet, since it's a sign that they don't respect my time. I expect that had I gotten the job, they wouldn't have respected my free time or created a good work/life balance. Regardless, it has left a bad taste in my mouth. After I've spent about 12 hours of my free time (in addition to my 40 hr/week job), the least they could do is give me 15 minutes of their time to call or write out some comments about it.

We used to ask job candidates to do something similar.

Since then, publishing code samples became the normal thing to do, so we simply require code samples instead, and give out the coding task only when they have nothing at all to share with us.

If you're in the job market, publishing some sample code, even if it's just a throwaway toy instead of, say, a full blown OSS project, can be a great tool for people to evaluate you as a candidate.

His complaints seem to be that this method of take-home-project is not as good as the method of hiring the candidate to work in the office temporarily for week's trial. That is true, but this is still superior to a typical interview. (Also not all candidates and not all employers can spare a week to do a trial.)

Nevertheless you should never agree to complete a full production project without being paid.

I happen to really like coding challenges. I much prefer them to a "technical interview" situation, which I find very stressful--trying to answer difficult questions in real time.

However, the coding challenges I've done for applications have always been in the vein of "solve this interesting puzzle and show us how you did it", not "do some boring day-to-day work, but do it for free".

To my mind the ideal challenge is no more than 4 hours. You make an appointment. At the agreed time, the hiring company emails you the requirements. If you have clarification question, they remain available throughout the challenge time to answer them. From a hiring point of view the challenge should have some vague areas in the requirements in order to test whether the candidate is a coder or a developer who asks decent clarification questions. The challenge requires no special tools to do, either JS in a browser or Python or something like that. The exact requirments of the dev environment are specified at the time the appointment is made, i.e. if you want the person to develop in Python 2.6.3 or to use JS with backbone.js, then the candidate can get set up in a few minutes and be ready.

I consider 4 hours to be a max. 45 minutes is a bit short IMHO and does not allow for including unit tests. Also, I believe that a good challenge should ask for a complete set of unit tests as well.

But a full working MVP is way overboard and is too complex for the hirer to make meaningful decisions based on the outcome.

Any challenge should be followed up by an interview in which questions focus on the solution as developed by the candidate. The why of choices and the intent are important factors, probably more important than the actual code.

I agree and disagree. I am a candidate and prefer coding challenges provided they are reasonable. Meaning, if you are wanting to check the person's ability in x, check the person ability in x, not y. So for example give a starter code with part that would showcase person talent in x is left out. Yes, this involves prior effort on the part of the company to come up with this exercise and on the person. I don't quite vouch for code samples, because it is very difficult to understand where they came up with the ideas and who wrote the code, and if it was a multi-person project. In the former case, it is a very controlled experiment and one you designed, so one can judge much better.

The code challenge is usually just one part of the interview process to see if you can produce a quality product within a certain amount of time. It's not designed to tell every single thing you outlined in your post. It's meant to provide some signal before the actual on-site interview occurs. The on-site interview is expensive on the company's part, it is easier to filter out people who can't solve a simple full-stack solution. Companies who ask things like these are looking for people who understand both front and back ends. In short, just knowing either front or backend but not both, is not enough for the company.

I find it amusing that many people (seemingly Hackers) concentrate on Wolfram's ego rather than on the actual thing at hand. I don't care about egos, lipstick color, or the pants the language creator wears. I care about the language, so let's talk about it now:

From a long-time Mathematica user: this is not a language I like. I use it, but there is little to no fun. Many things aren't immediately clear or become problematic if you stop using the language for a while. As an example, quick, what is the difference between Module[], Block[] and With[]? Even if you remember that With[] is a lexical scoping construct, Module[] and Block[] can be confusing.

It doesn't help that Mathematica is absolutely horrible for debugging code. I don't know why they put so little emphasis on their REPL, but it's way behind the times. Even mismatched parentheses can cause serious pain (and I hate the fact that things move around when I edit parentheses).

That said, I have a lot of respect for Mathematica as a complete system. It is incredibly useful, most mathematical tools you will ever need are there. It is also a great tool for explorative data analysis. Have a pile of data you'd like to see patterns in? Load it up, mash it into shape with high-level functions, then quickly produce great-looking graphics. Nothing even comes close to the flexibility of Mathematica here.

These comments would be a lot more interesting if people identified what was cool rather than just bitching about ego or syntax or licensing. I'm not going to be using the Wolfram Language, but I'd love to identify the best ideas from it. And it's a different enough language that I am confident there are interesting ideas in it.

My own contribution:

Idly looking about I come upon this page, which is not particularly notable: https://reference.wolfram.com/language/ref/Sow.html

What is notable is this example:

  In: Reap[Sow[a]; b; Sow[c]; Sow[d]; e]  Out: {e, {{a, c, d}}}
Reap/Sow ss a funny language feature that I haven't imagined before, but that's not really the point. The point is that this is a runnable example that's actually what is output. Typically when you run something like that you get "NameError: a is not defined". And "a" here is really a variable, of sorts it's not a string or symbol (at least not a symbol in the sense that we know them in programming).

Given this, snippets of code are just as executable as entire programs. Every expression is like a function with the free variables as its parameters, and a sequence of expressions is a bit like function composition.

This is all natural from the perspective of mathematic notation. In a more traditional programming environment I think it's reminiscent of partial evaluation: https://en.wikipedia.org/wiki/Partial_evaluation where you analyze a program and execute expressions opportunistically. It's really almost the same as partial evaluation, but the Wolfram Language knows a lot more about how you can execute different combinations of expressions than a typical language. A typical language does not really "believe" that (a+b) and (b+a) are equivalent. It doesn't know how to relate different operations. Nor do normal languages have a concept of simplification, so they can't speculatively try other arrangements (where none in isolation is clearly better or simpler than another) to see if simplifications are possible.

So looking through the documentation I'm still seeing an issue I've been dealing with MMA for years now. That's that mms acts as if all data comes in a single type. The real world unfortunately is a very messy place, I deal with numeric, categorical and boolean data regularly.

For example, I saw the "machine learning" section in the documentation and my eyes lit up. It has a Classify function. Then I looked into it and it assumes all your data is homogeneous.

Worse still, the only underlying classifiers available are rather pedestrian. I was using KernelMixture for my own classifier, which vastly outperformed the GLM or Probit models available.

Also, no Bayesnets?

NB: I'm user of Mathematica, and would love to use it more, Every time I have to use something like python or ruby I feel like I'm going back to the stone age.

One has to take a grain of salt with Stephen Wolfram's claims of superiority.

Nevertheless, it appears that people have to pay to use "the Wolfram language" (although there might be scenarios that allow "free usage" for the purpose of attracting users who will eventually pay for using the language if they want to scale up their work). The concept of paying to use a language is troublesome in terms of common understanding of what a language is.

And the documentation was great: you could evaluate examples right inside the doc page, play with parameters, like in your own document.

The design of the language, user interface and depth and clarity of documentation makes me think that Wolfram Research is even more design-obsessive than Apple. Stephen Wolfram takes credit for too many things (like Jobs), but he also delivers amazing stuff.

Redis is one of the few examples we have of truly beautiful software: A simple and elegant rock-solid performer that just works like water.

The updates over the years have been useful and has tastefully kept with the true spirit of Redis - thanks for all your hard work Salvatore!

Apples iOS7 Native JavaScript Bridge strongloop.com

"Apples iOS7 support of JavaScript inline with your Objective-C code validates JavaScript as the leading (and only) non proprietary language that is supported within the iOS development environment by the device manufacturer."

Since when is Objective-C proprietary? Apple's given it a few non-standard extensions (i.e. blocks) but that doesn't make it a proprietary language. GCC and Clang are open source.

JSC was always there for years in WebKit source repository, and anybody could build native JSC engine. Well, it needs some extra works, but there're also some Github repos from other people.

AFAIK, the only difference to Safari was JIT compilation support. Because iOS doesn't allow executing dynamically generated machine code in 3rd-party apps for security reason.

Does iOS7 support JIT compilation on JSC embedded in any app? If it supports JIT, that could be a big news, because it means Apple finally allowed dynamically generated code in 3rd-party apps, but I don't think the day will come.

And personally, I don't see any benefit from JavaScript apps. If someone claims JS or any third party frameworks are better than Objective-C for iOS app, I would like to ask these things. (could be offensive, but these are actually how I feel from those claims)

Does it offer better auto-completion? Does it offer better syntax/semantic/type checks? Does it offer better debugging aid? (like GDB's execution rollback) Does it offer better accessibility to any platform features? Can I use new features immediately? Shouldn't I wait for 3rd party patch? Profiler for device and simulators? How's low-level access? If I have some trouble, how can I fix it without knowledge for lower-level (Cocoa/Darwin)? If I want to use C-based DSL? Is it safe for AppStore approval? What's the benefit of using open language on proprietary platform?

I mean, what's better with JS than Objective-C with Xcode?

If it can't offer any of those stuffs, it means it's at least 10 times less productive = 10 times more cost.

Well, it could make sense JS app for an Android app because ADT is too sucks so some extra wrapper can bring extra productivity. But for iOS, JS stuffs only degrade productivity by extra abstraction, debugging hardness and inferior toolsets.

I've been working with JavaScriptCore to facilitate the optional code-on demand constraint of REST, e.g. A client requests a JS representation of a resource, which includes what fields a valid resource has, type hinting so the client can dynamically build a UITableView with the most appropriate controls for each field, and validation functions allowing the client to validate a field when it changes or when its UITextField resigns first responder status.

I just had a horrifying thought: Aren't apps that download code banned from the App Store? If so, would this include JS downloaded at runtime to be evaluated with JavaScriptCore? What's the conceptual difference between this and a UIWebView opening a page that has <script> tags embedded?

That syntax for passing obj-c blocks to javascript is nice. I've never been a fan of titanium/phonegap but this might make it easy and fast enough to be worthwhile. Ideally I could use html for some complex interfaces seamlessly and keep native components (scrollviews, etc) elsewhere.

Objective-C isn't a proprietary language, as this author annoyingly suggests several times. Regardless, the new JavaScriptCore framework is pretty impressive. It would be nice if there were some official Apple docs beyond the one WWDC video, though.

I wonder if Apple would approve an app that downloads and executes Javascript using the bridge. Historically, Javascript has been an exception to the blanket rule against downloading code, but outside of a web view, that might not hold.

Very cool -- but would be nice if they could tie this into the DOM and JS context of a UIWebView, so we could have true HTML5/hybrid native apps.

I recognize this is pedantic but why does he keep using "surface" as a verb? Is there some new programming nomenclature I'm just now getting exposed to? If so, what does this mean?

It reminds me of a Java programmer I used to work with who constantly said he was "hydrating" his objects. I kept wanting to tell him he wasn't sounding as cool as he thought he was.

Shameless plug here:In case you need to use JS on older iOS versions, I created JavaScript bridge for Objective-C (and C).

It is a command line tool that parses Objective-C header files (using llvm) and generates the needed intermediate "bridge" files.Internally it uses the SpiderMonkey VM (instead of JavaScript Core)The source code and the documentation can be found here:https://github.com/ricardoquesada/jsbindings

Android KitKat ships without browser app. OEMs have to license Chrome unwiredview.com

This is fud. Browser is still in AOSP. Pretty sure this is it here:

https://android.googlesource.com/platform/packages/apps/Brow...

Obviously you can create the gui for a browser to access the webkit renderer if you didnt want this.

Anyway, this is meaningless. No one ships commercial phones without the Play store and Chrome will be just another app bundled with the deal.

Speaking solely as a web developer: good riddance, the pre-KitKat stock Android browser is a piece of shit. It relies on an old fork of Webkit that has none of the features of the modern web, no GPU support, and a lot of outright bugs (like it would flip back to the first frame of a CSS3 animation right before the animation completes, creating an ugly flicker).

Without this change we'd be left with Android Browser & clones as the IE6 of the mobile web. I'm hoping all the OEMs build their own browsers off the Chromium WebView that ships in KitKat; then at least we only have to worry about Chromium and Mobile Safari.

If only there was a free, completely open source browser with more than 4.5 stars in the Google Play store which could be bundled without any business deals...

Bonus points for a cool project codename like Fennec.

Are the additional terms for licensing Chrome beyond what was already needed for OEMs to get the Play Store? Unless there are and they're onerous in particularly new way, this feels like a non-issue getting attention because the business agreements around Android are relatively public compared to other OSes.

This seems a bit odd to me. The browser is still in the AOSP source (platform/packages/apps/Browser) and has 4.4_r1.2 tags. It was also included in a self-built rom for my Nexus 4 without doing anything to explicitly include it.

Even if google doesn't ship a browser in the source they provide to OEM's, the source for the AOSP browser is still readily available and trivial to add to the build.

One thing that isn't in the article: Chrome for Android is proprietary software. Yes it uses the chromium project as an engine, but all the UI bits are proprietary.

This leads to ridiculous procedures if you want to recompile libchromeview.so and replace it in your app:http://code.google.com/p/chromium/wiki/AndroidBuildInstructi...

Not only the browser in AOSP is based on chromium, but it's also used as the webview engine itself...

http://blog.chromium.org/2013/11/introducing-chromium-powere...

as much as I despise Google for closing up a lot of bits of android, this doesn't seem much of an issue...

also: every OEM worth its salt should just build their android from the AOSP (or some fork)'s sources

Before Chrome became the Android browser id led a dual life, as Chrome, Google's commercial product that includes some licensed IP, and Chromium, an open source project.

I expect that licensing Chrome in Android is necessary for the same reasons there are parallel projects and products for other platforms.
