Khan Academy and Bret Victor are apples and oranges -- they're not even playing the same game. In order to make any major strides, we have to reconcile the need for PRODUCTS, NOW! with the conceptual, exploratory approach taken here.

Real world innovation often makes very small tweaks on proven formulae, whereas bold new ideas can have a long incubation period with seemingly little payoff at first. It's roughly the difference between business and research. While it's not possible to "test" these bare assertions in the sense you imply, they can certainly be argued for and against. And he makes a rather compelling case for it, certainly a more nuanced one than much of the criticism here on HN.

In any event, he's begun sharing some of his code (I believe) and products like Light Table are emerging that appear to draw from very similar inspiration, if not his work directly. It would appear these ideas are gaining some traction.

Ask HN: Facebook's Project Prism
Google has published Spanner, a new database system, paper and world has stunned again. Most interesting feature is ability to serve (transparently) from geographically seperate data centers. It's a flexible "database" for serving requests ranging from ad display to analytics to search queries. OTOH, Facebook did the global-multi-DC for analytics seemingly because they (FB) talk Hadoop only not HDFS not HBase, but Hadoop [1]. At first I thought this is excellent then I'm confused. What did exactly they do? a) improved/forked HDFS b) improved/forked HBase c) completely new FS on top of Hadoop d) completely new db on top of HDFS e) ??

Codeacademy is awesome! The industry had to start somewhere and they've done a stellar job, but it could be even simpler.

That said, the issue the author appears to be having is specifically the disconnect between the marketing, 'easiest way to code' and the reality.

For example, my gf who is a non-coder but has modest computer literacy skills, tried it out for the first time last week (doing the python track). She was going fine until about 10 minutes in and didn't understand some really elementary concept, she spent the next 30 minutes trying to figure it out, got frustrated, and then gave up.

A quick win might be to focus on the community aspect more, helping each other, live chat rooms and forums, and explain the UI a bit better. There might even a tutoring revenue model somewhere in there...?

Technical people have years of built up mental models that we take for granted. You really have to take someone like your mom and put her on the site, to realize just how complicated it is for the masses.
.. but I see this trend toward video when text would suffice as evidence of a societal lack of good (writing) education

Think it's because there's so much written information now, I can't even read 1% of the stuff I want to. After reading "all day", good videos, e.g. talks, are refreshing.
MiniTest and Rails 3.2
I've spent the last decade writing debuggers; they are anything but omniscient. It's a miracle that they work at all, frankly.

In principle gdb could look at everything that's going on, but in practice doing so would (a) hit a bug in the compiler's debug output and fail, and (b) take forever for any program worth debugging.
Thanks Jacques. Author of that updated config post on rtCamp.com here.

I really think Nginx in still underestimated by large. Most article handles rewrite in nginx based on their Apache knowledge.

Nginx's try_files is magical. So does maps{..} section.

Using Nginx map, you can server static files in WordPress-multisite without PHP (much better than X-SendFile or X-Accelredirection). On large wordpress-multisite network, this can really increase Nginx's capacity by multifold.

I'm curious - how did you handle the collisions with objects? Did you run some sort of algorithm to auto-detect which objects should be solid, or was it all done by hand?
Not the same analysis, but a technical comparison anyway:

Not that I think a display being numerically slightly better than the other removes the bullshit from “my phone is better than yours” conversations.

I still find PenTile unsightly though.
As a general rule of thumb anything that generates static assets will be a perfect companion for Harp. There are some other goodies too, but we are still experimenting with those features.

The music thing on the lock screen changed for me a few months ago. I'm in Germany. So apparently they make available features elsewhere slowly but they eventually get there. Local search works fine here too, although Germany is probably a bigger market than Denmark.

I haven't actually used Self, but from reading the paper, discussion of embodiment, tangible objects, and direct manipulation makes it interesting from a visual perspective.

Personally I think all computer languages are textual by definition, and vary in the amount of extra visual support for syntax and more often secondary notation. The Reactable perhaps pushes beyond this limit by making proximity and orientation part of the syntax, but still is basically about composing textual symbols.

If we're doing that thing, I wrote a chapter on this in my thesis :) http://yaxu.org/thesis/

So the design on my iPad looks pretty good, they may have preferred the form factor of the iPad in the design process.

However I'm having the same issue with loading times on my 3GS connection. My 3GS connection is pretty good. I can watch Youtube videos over it. And yet the experience in the App Store app is not so good.

Don't know what's going on there, but I suspect they assumed most people open the App Store when connected to Wifi.

Thanks! Agreed. Dropbox is a significant step forward when it comes to getting assets into the cloud. I think it will make life much easier to be able to iterate on sites within a directory on your file system with no extra bagage.
I doubt it. It's probably the third revision of that blog post, the other two are just unpublished.
I'm curious about this as well. Does it handle the build? Does it handle the subtle differences between pure web and Cordova (deviceready vs ready, etc)?

I have used D but no Rust yet. They look superficially similar.

On the Rust side, algebraic data types, an AST macro system, saner tuples, non-nullable and immutability by default. I'm a bit skeptic about the different pointer types and how they will interact with meta-programming.

On the D side, many good things like unittest(), best-in-class overloading support, compile-time everything, etc.

> What does that have to do with pills?

We're discussing supplements, which are usually sold in pill form.

> If people are making any kind of food at all that is filled with trash then the FDA should stop them, but it has nothing at all to do with them being supplements.

Should, yes. However, if you read the article, you'll see a very bad law that prevents the FDA from doing so in the case of supplements.

> Snake oil at least was (usually) what it said on the bottle.

Really? I don't know one way or the other for sure about historical snake oil: My usage there was 'snake oil' as a synonym for 'an untested product guaranteed to cure anything and everything, sold by a con artist'.

Sept. 27, 1822: Deciphering the Rosetta Stone Unlocks Egyptian History
That's unusual, here in the UK, we have a large amount of untapped talent without the quality employers, the average wage for a web developer in the UK is in the £20k-25k range and job satisfaction amongst the ones I know tends to be quite low, it's a much different scene.

I come on HN to dream about moving to CA, because one day one of these job ads will apply to me.
Japanese gate agents (and almost every station has one) are usually very cool about it though: they'll ask where you came from and how much you paid, and most of the time will just trust you and charge you the difference or at worst just the price of the ticket. I've lost tons of tickets and have never been charged anything near the maximum price.

[Looking like a foreigner is also probably a benefit in this situation, as they'll assume you don't know the system well, and additionally don't want the hassle of arguing with you.]

That's one of my (many) reservations about POP ticketing (which is the darling of many transit advocates): there's a non-trivial chance of losing a ticket, and ending up paying very, very, dearly for a common honest mistake (typical POP fines for being caught without a ticket tend to be hundreds of dollars)...
>Stack-allocated data lets you often avoid dynamic allocation overhead and garbage collection (even closures can sometimes be entirely on the stack).

There's an entire website named after the results of over-using the stack. Smart pointers and move semantics in C++11 completely smoke GC and memory management everywhere else.

While I'm sure Rust is a nice language and I applaud its innovation,there's already a perfectly good wheel.

Valve going into hardware is definitely one use of Linux support, however another is as an alternative to Windows 8 and OS X. Both Windows and OS X are moving towards an locked-down, app-store model and Gabe Newell recently expressed concern over that move. At the same time, Ubuntu is being sold pre-installed on computers worldwide (though less so in the US and UK, more in emerging markets). I'm not saying that Ubuntu will reach OS X's current level for Steam users straight away, but in 5 years or so, it's definitely possibly.

I have also found most (if not all) points here to be true. Good essay.
But that aspect of Self comes mostly from Morphic. Anyways, Self/Morphic were a huge inspiration on my own work. There are deeper distinctions between textual and visual; think a Van Goh painting vs. a book by Steven King. They say "a picture is worth a thousands words," but actually, the worths are not very comparable. Text is much better at expressing abstractions than visuals are, which is why most VPLs mixin some text (though their are pure VPLs like SketchPad and ToonTalk).

I skimmed your thesis a few months ago; lots of good work there! But I think we are a bit out of whack on our world views (arts vs. PL), which is why we might not be talking on the same page.

> if the FDA could prevent people from selling harmless food items

No. Supplements are not food, legalistic tricks notwithstanding.

> But not just actually dangerous supplements, but potentially dangerous supplements too.

Well, yes. Or else you're fraudulently using your customers as test subjects. People get angry enough when video game companies do that.

> This would effectively outlaw the sale dietary supplements

Why would this be a bad thing?

> What's so bad about the status quo, anyhow?

Massive amounts of fraud.

> The author gives a few examples, but almost without exception they are issues which are already solved. That scary story about the NJ factory? Yeah, that's actually ALREADY ILLEGAL. The owners WENT TO JAIL. After being discovered by FDA inspectors, who ALREADY have the power to inspect factories.

Interesting how nobody's found half a rat in a factory that makes actual drugs, as opposed to "officially-not-a-drug" supplements.

We need to raise the standards to make the bad things less common. Getting supplement makers up to the standards drug makers are would be good.

> If that's a reason to effectively destroy the industry, then god only knows what we should do poultry farmers after the various salmonella outbreaks over the years. Shoot them, I guess?

No, just raise the bar. Same as here.

> And finally, to cap the entire piece...the author complains about the FDA not doing a good job of enforcing existing regulations. Which is...an argument for giving them more regulations to enforce. Uh....what?

More and better regulations and more funding, yes.

> Where I come from, serious failure on someone's part is not a good argument for increasing their role and responsibilities.

So, given the failures of the free market to put fraudulent supplement makers out of business, why would we trust it to do so in the future?

Same comment I put on the blog, but keen to hear HN responses. Why do so many freelancers gravitate to small(er) clients? It seems to lead to direct competition with platforms such as freelancer.com, odesk, elance, etc which is impossible for a local freelancer.

Clients like digital and creative agencies, funded startups and corporates (managers that don't have access to internal dev resources, but still have dev needs). They use freelancers and they don't come with a lot of issues small clients have.

Interested to hear from freelancers as to how and why they work for smaller clients.
I'm not making any claims about Apple catching up to "searching" - That truly is a field in which google has demonstrated they have unique, and proprietary advantages over the competition. They have deep research and superior search algorithms, and I would say only Bing can give them competition, and I don't believe Apple will ever be able to provide similar capability when it it comes to that.

But the elements of mapping that are not related to search, that is, routing, displaying tiles, walking directions, cycling directions, turn-by-turn, aerial-view, points of interests - these are all elements that internet data is less useful, and where being able to invest billions of dollars in acquiring suitable cartographic information (as Nokia did) should be sufficient to put together a world class map environment for the customer. My perspective on the challenges is mostly informed through several hours of reading historic postings here: http://blog.telemapics.com/?p=399

In all likelihood, after several billions of dollars invested, Apple 2014 will equal Google 2012 in the areas I just described (mapping sans search).
"he wanted to make sure he could transfer his stuff onto a new iPad in case this one ever broke"

Ask HN: Would you need a collaborative LinkedIn connection search tool?
The idea is that looking for connections through LinkedIn for a startup is a pain as one must ask to everyone or go log in as each member of the team to find people to introduce them to identified prospects.

The envisioned tool would simply propose to create a group and OAuth everyone within that group so that collaborative search for connections become possible.

Would you use that tool? Anyone interested? Any remarks?
My major problem with Bing is that it defaults the interface language based on your location. This is stupid. If I'm travelling in China, then having the entire interface in Chinese is completely useless.

Bing like many other major sites, make the poor assumption that the user's location == preferred language.

From a usability perspective, the interface language should primarily be based on the browser user agent Accept Language, and THEN an ip-to-geo database lookup can OFFER the user the location based user interface language.

Finally there should always be a way to change language.

Bing, as in the entirety of Bing, does not have a way to change language. I am currently in Germany, and there isn't a way for me to use the maps in English.

It is a schoolboy mistake from a major player. Idiotic if you ask me.
Now I urgently want this trial to be over.

The upfront depends on the project as well; some projects have less, some have more; depends on the size and the number of milestones. If you have, say, a project of $10k with 4 milestones, I would never do a 30/70 payment. Rather 30/10/10/20/30 or something.

Also, you can use the popular agile approach which is popular; in that case you define stories per sprint (which in smaller projects are a week usually) and every monday morning you agree with the client upon the stories to be done that week. When you finished the last story, the client needs to pay the price for that week and go on with the next week. This keeps both sides alert and doesn't allow for slacking on both sides. It can go very wrong if you agree to too much, then you get the dark side of agile which means you'll be working every weekend 24 hours/day to make that monday morning.

I think that's because they have a lots of Java code to compile. When there are a lot of GO codes to compile, it will take hours as well. I doubt GO's compile speed is significantly faster than Java. Both of them don't have the dependency problem plaguing C++. It would be interesting to compare the two.
