Isn't this ultimately up to the congestion control algorithm that is used alongside of UDP? Aspera and UDT, for example, have tunable congestion control that can be more or less greedy.

I'm not a protocol hacker, so hopefully one will weigh in here. But I do remember some Sky Is Falling discussion over uTorrent's use of UDP for transfer, and the uTorrent line was always that they were implementing UDP transfer in a way that played nice with TCP.
Heh! They'll turn around and sell this "study" for millions of dollars and will keep the mouths of McKinsey new hires moving for a few hours more.
>If it were not for women, I'd just sit home playing World of Warcraft, drinking energy drinks and masturbating, to put it bluntly.

This is where I think your argument falls apart. It's not because of some drive created through scarcity that encourages you to get up and be productive, its to gain social status (as communicated through wealth) to attract women.

This drive will be ever present in a society where basic needs are free. The only difference is that one will have to be more creative and intelligent to stand out and attract a mate. As society evolves, one's criteria for a mate evolves with it. But that drive to acquire status is ever present.
There is a bit of clutter, in the traditional education space. However, there wasn't anything with a good online presence, so we thought it was a great name.

Not going to be able to buy treehouse.com for awhile though, as they want $1m for it.

It'd be interesting to see how your (and other's) setup have endured actual attacks. As someone non-versed in security, I think your approach sounds great. But how does it fare when someone comes knocking?

I wonder the same thing about my setups. I have a password manager with random passwords for every site/forum that I encounter. It'd be nice to know of the efficacy of this work - has it helped me in any way? I'll never know.
Who is the current centralized authority that figures out the shortest routes today?
Why would you need a mile in an urban environment? Trace out a circle with that radius in Google Earth; it's an absurd range.

The idea is that you have a pretty high density of users. 100 meters would be more than enough to cross any street and reach several buildings away in any direction. Even in an American suburb, it'd reach a few houses away. That's a realistic goal: 100 meters, not 1600.

Isn't there going to be an increase in SSD's too?
Assuming that EC2 is on a shared network with S3, you could do something like the following:

CLIENT <-UDP-> EC2 Instance <-TCP-> S3

Not certain if it is worth the hassle, though.
Hi Chris. Great news! We already have Captions. If you see any videos that don't have them, could you please email us and we'll take care of it: help@teamtreehouse.com

What most articles fail to address is that most of the big brands have factories here and that Thailand accounts for a way too large share of the production of hard drive parts, regardless of brands. In other words, Thailand is the SPOF of the hard drive industry.

Also, FYI floodings are expected to last one more month (water just isn't flowing that fast) and factories will need time to recover and reach 100% operation (not to mention the overall infrastructure damage). The one month thing is an optimistic estimation from the government. A practical example: some Pakistanis flooded last year were finally getting back to normal when they got hit by this year's floods. No one really know how long it's going to last in Thailand.

WD, in a statement a few days old, said it expected to get back to full normal in the summer.

Edit: for those who just had no idea: http://www.boston.com/bigpicture/2011/10/thailand_flood_reac... (I used to live a couple of blocks away from picture 7).
Now, I've coded a lot of stuff in Objective C for iOS, and it works just fine, and I actually think it's a pretty good language. I'm glad that Apple has helped bring it more into the spotlight.

But ramitos is right; it really is a Frankensteinian bolt-on addition of Smalltalk, syntax-wise. The message passing code simply does not look like C.

That said, I'd encourage everyone to give it a chance. I, too, had a negative reaction to it when I first encountered it ("It's so ugly!") but you get used to it, and then it's fine.
I think the lol refers to the fact that Brazil is counted twice.

"Watch videos and take tests"

Am I missing something? That's your learning method? Nothing interactive? No coding? Videos may be a fine way of understanding a process but it's not good for something as in-depth as coding. You don't learn code by watching videos of others doing it, you learn by coding.

The site design is nice but you'd need to offer a lot more than videos to get me to sign up.
to add, if you haven't read Brad Cox's books then you really should. They are not heavy technical, but give time to some serious ideas. They are a little hard to get ahold of these days.

Any economics text books will do. It's taught in most college sections in France.
I was not concerned with fraking until I read:

"the heavy trucking required for fracking inflicts major damage on roads"
The site looks great and very user friendly, but as others have pointed out, the paid-tier-only seems too restrictive. Specially given the motto of treehouse is "Millions of people can't afford a quality technical education, or if they can, it's out of date immediately when they graduate. We aim to change that."

How can this compare to MIT (and other) Open Course Work and hundreds if not thousands of good free tutorials on the internet Vs $25/$49 a month?

FWIW, I learned basics of web development/design totally free, just took a bit of searching to find good resources, and once I was confortable with basics, the further education came through just googling-on-demand, videos only helped in the beginning.
Barnes & Noble launches Nook Tablet, lights a fire under Amazon
Congrats on the (re)launch! I used ThinkVitamin a little bit earlier this year, and it's great to see you guys moving forward. It wasn't for me at the time, but may be in the future. I don't know if it was just the timing (I was really busy) or the format (video isn't for everyone), but I was impressed with the product regardless.

One thing to note on the new site: clicking "Sign your team up" on this page: http://teamtreehouse.com/groups just takes you back to this page: https://teamtreehouse.com/subscribe/plans, where clicking on "Sign up" takes you to a page with no indication of how to sign up for a group plan.
That usability study has already been done in 1980s and published in CHI, the conclusion is that vi is a better text editor than emacs.

There might be something to do with pension plans as well; the current cohort of retirees got quite generous (by both historical and current standards) defined-benefit pensions.
What do you set the limit to? What do you do when a router fails and your available bandwidth suddenly drops? All of the TCP end hosts will backoff properly and avoid melting the network with endless re-transmits. All of the TCP flows will converge towards sharing the available bandwidth, even if that is a moving target. Applying a congestion control algorithm on top of UDP like the other response says is fine. Perhaps TCP's specific congestion control scheme isn't what you need (it sucks at live video for example). But you really do need a congestion control algorithm.
Two specific cases:

The Fourier transform can be thought of as representing a point in infinite dimensional space as the amounts of each component. The sine and cosine waves are orthogonal (in a technical sense) and of "unit length" (in a technical sense), and all we're doing is, for a given "point" (function) in our vector space we're finding out how much of X, how much of Y, etc, is in that vector.

Second example, Goodstein's theorem is trivial to prove if you use transfinite arithmetic, but has (some claim) been shown to be independent of the Peano Axioms, and hence impossible to prove with finitary methods. (There is also a claimed proof. If both of these are true the Peano's Axioms are inconsistent)

Sometimes the infinite is easier than the finite.
I was more angling at whether you're concerned about litigation/C&D from existing players defending their TM. It's a great name, but potentially provides an unwanted complication down the line.

I dunno--in an age where we have actual, halfway decent garbage collection, referring to ARC as something that might compete favorably with those "real" high level languages makes my eyes go a bit crossed.
I don't intend this comment to be an insightful deconstruction of the NoSQL space and/or Mongo... but does anyone else notice that the level of energy around a project (positive or negative) usually indicates its progress along the hype-dissolution cycle[1]?

I try not to take the actual comments or articles as law, but rather use them as a temperature reading to figure out where in the slope we are currently for a given tech or trend.

Given that Mongo-talk has absolutely dominated HN over the weekend as well as reddit/r/programming, I am interpreting this as being in the bottom of the dissolution curve right now.

It is this point where the community push-back and temporary "hating on" forces the team to go into overdrive, addressing whatever pain points the community has griped on the loudest, in this case:

- Write locks
- Durability / Replication consistency (already addressed)

This is like tempering steel by pounding on it... but instead it is the community pounding on the people over at 10gen. That sucks, but this right of passage for them will see sweeter days on the other side.

I imagine Mongo 3.0 will represent the final climb out of the dissolution curve where all open complaints have been addressed and we actually get back to solving problems with the technology.

I don't know that Cassandra or Redis or CouchDB have completed their hype-cycles yet, because they haven't had the hyper-aggressive response from the community during the dissolution step. They are all popular and well-liked, but it seems like their popularity is still climbing.

It is all interesting none the less. Mongo is a huge success, regardless of how many of these articles are written.

I've not seen a team as dedicated and involved like 10gen is for a long time; Eliot still answered 100s of messages on the group every week (Along with every new member of the team) -- which I find the biggest indicator of Mongo's future success. If the CTO is carving out that much time during the day to stay involved, while still bug fixing, replying to posts like these and testing bug reports... that's a lot of love right there.

Seconded, also on Win7/Chrome and http://i.imgur.com/XSfw7.png is what I get. I've seen this font in use several places on the web (some popular tumblr themes use it) and it always looks horrible.
nodebeginner.org was awesome for getting acquainted with node.js. I purchased the book and was a bit disappointed that it didn't add a whole lot more than the tutorial but I was glad to support your efforts. Thanks for making this.
I'm in a similar situation (except with an even bigger tech company) but I work in a geographic area with no other tech employers. I do believe this cuts down on the number of people leaving for greener pastures and helps keep salaries down.
For those wondering about it, don't bother searching for 'NewSQL'. It's a buzzword that doesn't actually mean anything other than 'it's not mysql, pgsql, oracle, or mssql.' They claim to improve on the standard DBs, but every single DB does it in a different way. The name is useless.

Instead, read the 'who we are' and 'how it works' bits on NuoDB's page. They were much more informative.

I think it sounds exciting and fresh... And doesn't seem to be open source at all.

I'm not allergic to paying money for software, but I've found I'm happiest when using something that I can guarantee will survive, even if may have to do so by my own hand. Commercial products have a tendency to be a pain in the rear.
Windows notifications are very annoying, and I'm glad OS X doesn't have them. OS X has dock badges to notify the user, and if apps do their own thing because they think a popup just has to interrupt what the user is doing, they are deviating from the system's APIs.
Ah, yep. The jokes on me:) I missed that.
You don't increase wealth by being inefficient. The cult of startups leads to more startups, but it doesn't make them more successful.

There are some exceptions, but the market can always be irrational for a little while. LinkedIn and GroupOn aren't real businesses and eventually the stock price will reflect this. However, in the short run they are able to pump the stock price by having a microscopic float and getting listed on things like Russel 2000.

Oracle, Cisco, Intel, HP are all startups, they are just very old and established. They employ tons of people. They aren't doing us any favors if they barely survive, however. Inefficiency makes us all poorer, even if in the shortrun it makes some people better off because of a paycheck (HP employee for example).

Difference in definitions: I read "approximate solution" as an "approximate route," as in the node choices are approximated (potentially leading to a wrong final node, or losing packets at a dead end). Instead, finding approximately the shortest route that doesn't lose packets and gets you to the correct node would presumably work.
The exact same thing could occur if another (unsalted) hash becomes as popular?
I'm not versed in the entire complexity of the issue at hand here, but isn't putting the text book in the hands of teachers a kind of reform?

Wouldn't having a teacher, or teachers, write their own text books give them better control over what to teach?

Couldn't a collection of teacher add something to the curriculum through the text book and watch it get adopted higher up structurally based mostly on the fact that if the teachers teaching those students specifically added material they found was necessary then it must be important enough to require it officially.

The story is written as a money saving venture first, and then a better alignment of course material to state standards, but I'd also like to think it might democratize what those state standards should be amongst a population of professionals who interact on a daily basis with the people who have to test against those standards.

Then you are, in fact, a douche.
This is funny. I thought that the whole paradigm of startups is to first release the minimally useful featureset and work on the other items later? I mean - isn't the goal is to first get revenue and then fix up what needs working later?
Pretty sure he's not advocating actually making a mile square cube of battery. He's just illustrating the scale of the problem. It's the same amount of battery no matter how you divide it up.

Efficiency is definitely some low-hanging fruit. It only gets us so far, though. Rooftops are probably the most effective place to deploy solar, but housing is only one piece of the puzzle.
>Gladwell [...] adds this marginally related story about tweakers so the entire article isn't regurgitating [...] anecdotes

I think you're missing the main point here. The computer revolution, as a large scale technological and social transformation, does bear comparison to the Industrial Revolution. Where does someone like Steve Jobs stand in this comparison? He was obviously neither the inventor of a fundamental technological advance (James Watt) nor the guy who provided the money and business expertise (Matthew Boulton). The article makes a good case that the closest analogy is actually with the people who took Watt's steam engine and eventually improved its efficiency fourfold (and, BTW, the term "tweakers" comes from the referenced Meisenzahl & Mokyr paper).

Anybody know why they changed the name? Nimbus seems more pronounceable.
I too learned Dev and Design through free resources and googling (It's still how I learn), but a lot of people find value in having a path laid out to them, and having consistency in the resources they learn from.

Of course a lot of people on HN are going to be people who taught/teach themselves everything, but a lot of people want some hand holding, and that's what we aim to provide with Treehouse.
Amazon SNS now supports SMS in the USA. But what about the rest of the world? USA is around 5% of the world mobile market.
We are happy to (re) announce that with Amazon SNS and Nexmo you can reach the remaining 95% without much change of your existing code!
Using the Nexmo Amazon SDK, you can easily subscribe your mobile users to a given topic and they will be automatically notified via SMS when you will be publishing messages. Here is a detailed how-to: http://www.nexmo.com/documentation/libs/index.html#sns

What is also very cool is that you would benefit from Nexmo wholesale pricing and 1-hop model that cuts out the middle man, improves SMS deliverability and reduce latency.
I'm not 100% sure on this, but I think that part of what makes the longer range nice is that it requires fewer hops and thus lower latency.
Sometimes the Outage is Your Fault
You could try `time psql < alter-statement.sql`. I know, it'd not really be useful as it measures lots of overhead. But if it's fast on that, it's fast during an active session.
Is SAP deceptive just because one popular organization prefers another definition of open source?

It's not because the OSI prefers, it's because it's the mainstream, generally accepted current definition of the word. I mean, if I sold you a "broascasting system", would you accept something that casts seeds out?

The term "open source" itself should not imply a specific license

It doesn't. It implies a set of conditions they have to meet. BSD, MIT, GPL, Apache, WTFPL, are all different Open Source licenses.
To be completely honest, I have never heard the term "NewSQL" before in my life. After a quick Google, it seems that the term basically means "SQL databases that go FAST LIKE NOSQL." (Though it's not really popular.) Which is, once again, completely missing the point.

I can't speak for professional devs - I'm just a hobbyist - but I'm not developing for "NoSQL" databases like CouchDB and Redis because I want to do SUPER WEB SCALE. I'm developing for CouchDB and Redis because they offer truly interesting alternative ways to look at your data. (In fact, Redis is what got me interested in data structures.) And if I wanted to write a project that used data that makes sense from a relational standpoint, SQLite (for development) and Postgres (for production) are just fine with me.
One thing I forgot to mention: Wordpress/Automattic, Living Social, and BankSimple are going to be interviewing Treehouse members who are looking for work and have unlocked certain badges. We'll contact Members who qualify.
Memrise - vocabulary learning and memorable dictionary
Ask HN: What's missing from government data APIs?
There seems to be a lack of centralized data available over an API. GovTrack does a very admirable job, but doesn't provide data in JSON formats, and has recently deprecated its congressional member API without a replacement. The New York times has decent APIs, but districts are only available for New York state.

A decent, modern, fully featured government data api (including state and local data) could be a real boon to social good, but would anyone use it?

In terms of size, they're almost the same (Objective-C classes are implemented with structs). In terms of speed, the difference is absolutely huge. You can generate a random number faster than you can make an Objective-C call.

Thanks for the heads up (was looking for more real info and not the damnable 'beta signup' form)

This sounds like SQL ontop of Cassandra (for a more or less mental-map if you are looking for one):

Our distributed non-blocking atomic commit protocol allows database
transaction processing at any available node. The system is
designed to provide a consistent view of data, high availability,
and the ability to detect and manage partitions in a predictable
and consistent manner. Query processing scales with the number of
available nodes, storage scales according to the choice of storage
manager of which there are many. Storage managers are key/value
storage engines that also operate as a distributed in-memory cache
and participate in the commit protocol to ensure durability
guarantees.
Let's take an example - Etsy has grown to 80 engineers in the last year. If 50 of these workers had decided they wanted to go their own way and create a startup, how many jobs would have been created and how many of those people would be out of work?

Easy money at the seed stage means a lot of companies that are small ideas trying their hand at building a business.
Riak has secondary indices, and map/reduce for ad-hoc queries. You can store raw binary data in it, and it's happy with that, but if you store JSON then it can query it. From what I can tell, the biggest difference between Riak and Bigcouch from a data model POV is that Bigcouch has materialized views, while Riak's are ad-hoc. I'm not an expert in either though...
