Depends a bit on the area. You can machine-code results if the field is extremely static in its conceptual and epistemic framework, so it's just a matter of slotting new things in place. Some "industrial-style" science does work like that. But large areas don't.

Most of the articles I read have the majority of the actual research going on in the text, not in whatever the "results" might nominally be. For example, a programming language paper might prove a few theorems about type-soundness, but it's rare that a new type-soundness theorem is really want you want out of the paper; that's just supporting apparatus. What's more interesting is the design discussion, motivation for why this feature was introduced and how it relates to previous features, explanation of how it was implemented, discussion of variants and future work, etc.
> I remember reaching the level of ordinary differential equations and realizing that "most" non-linear equations had no exact solution at all.

This may be a bit theoretical for most readers, but every ODE that has one and only one solution has an exact solution. That the best definition for that function is "the solution to that ODE" does not mean that the function is any less exact than something you can construct out of exp, sin, cos, etc. In fact it would be completely reasonable to define exp as a solution to a differential equation and then to prove afterwards, that exp is equivalent to the usual power series and accidentally also has some other nice properties :).

This stuff annoys me, "Ovshinsky’s achievements are all the more remarkable because he had no formal qualifications beyond a high school diploma."

It annoys me because the guy clearly had the equivalent of a Phd in materials science, he just didn't happen to get it at an accredited institution.

The annoyance comes from the people who read this and say "Gee, even somebody that never went to college can do this." rather than "Gee, you can learn anything even without attending a college if you have the drive." I got similarly annoyed when someone with a PhD makes an assumption that because someone doesn't have a PhD they must not be able to get a PhD, but knowledge isn't like that.

Rather than pitch this guy as someone with no formal education, we should hold him up as someone who chose to educate himself deeply in the subjects he was passionate about. To seek out knowledge and to hone his ability to separate truth from fiction, insight from platitude.

Because more and more people live in London (San Francisco, New York, Hong Kong, etc.) now - it's too crowded there.

Wealth is not income though. Higher wealth taxes would go a long way but then you again have the problem of the wealthy simply moving their wealth out or not bringing it to the high-tax country in the first place.
I did read the article; I don't know you jump to the assumption that they are collecting welfare. If you know otherwise, please provide the citation.

It is possible to live quite frugally. Some of these people are, as the article states, getting help from other people; that doesn't mean they are getting help from the government. BTW, only one person mentioned OWS.

Regarding the Macbook. . .you assumed these people started with absolutely no possessions. I assumed they brought some possessions with them, including the Macbook. Nowhere does she state - or is it impled - that she bought it after beginning her voluntary poverty. Also, even poor people - whether the poverty is voluntary or involuntary - receive gifts. In case of voluntary poverty - where friends and family are most likely not poor - it is quite possible to receive a Macbook as a gift.

I've known people who've done this - and are still doing it. Just as the article stated, most, if not all, of them came from relatively privileged lives and always had the option of returning - or at least moving up from relative poverty.

Ask HN: How is it to work at General Electric?
I am currently looking into GE for a possible internship (I am a junior in CS from UIUC). The pay is moderate to low for the usual internship offer, and I have other offers that pay significantly more.

However, I am curious if anyone has experience in software engineering in GE, more specifically GE Energy Management? If so, how would the experience compare to say working at Facebook, a financial firm, or else where. GE seems to offer a significant amount of benefits, learning opportunities and is growing out its software side rapidly, but I have no insight as to the working environment.
I don't know about the OWS and NYC kids, but I highly doubt Dan Price (the guy at the top living in a hobbit hole) is on welfare.

When I formerly lived in a tent in West Virginia, I knew lots of people who lived in similar "intentional poverty". Many of these people had seasonal jobs. Where I worked as a whitewater rafting guide. None of us had to pay for housing beyond just having a tent because we set up on the land owned by the outfitter. At the end of the season, half the guys went off to become ski instructors, often at places that similarly put them up for the winter. Many of the guys who had been doing this for a decade or more had enough cash saved up each year to go to Belize where they had similar arrangements for free housing and would raft for fun with raft guide friends in Belize.

During the summers I lived there, I actually could eat and drink purely off tips from customers and didn't touch my meager salary which all went into the bank. I banked enough during the summer that I could easily have purchased skis and hit the slopes as a job for the winter if I chose or live in a tent in Belize. The simple life ain't that hard if you live in the outdoors.
New Friend Request... This is Not an LOL Matter...
This is exactly the logical fallacy the article is adopting. The fact she is using a $1000+ laptop, when she could buy a much cheaper non-apple laptop? It doesn't make sense with the frugality "lifestyle."

You have the absolute minimum income in a highly expensive city, so it only makes sense for you to have the best?
I found Sneakers a little disappointing.

Don't get me wrong, it was a pretty decent 90s thriller. Very charming. But the way it was described made it out to be as if it portrayed complex cryptographic and technical concepts.

All I really saw was an anagram and some idealized substitution cipher. Fun film, misleading summary.
It can happen quickly given the right circumstances. In machine learning, the editors of Machine Learning resigned en masse and set up the open-access Journal of Machine Learning Research, which became the top ML journal quite soon after being launched: http://jmlr.org/

The old ML journal is still prestigious as well, but there's now an open-access alternative that's at least as good and probably somewhat better.

I think this idea would be even better if instead of recommending services (since people will be divided anyway), they would recommend protocols/standards, for each case. OFC cases like bitcoin, that is really stablished, should just be named as the only suggestion.

Lisp has images too. Ruby copies the Smalltalk OO model pretty closely but what Smalltalk has that Ruby doesn't is automated refactoring, that ability comes from being image based rather than file based. Ruby is a very practical modern Smalltalk frankly.

Perhaps we are talking about different scenarios. From what I'm reading (correct me if I'm wrong), you're talking about people who stop being creative and never recover the urge to be creative again. The scenario I have in mind are people who stop being creative, and find when they want to be creative again they don't know how to do it. There's a subtle difference, and it comes down to honesty. If someone is honest about their intentions, then what I'm saying is there's a process they can follow to rebuild their creative senses. If they're not truly committed then there's not much point discussing what comes out of that half-arsed intention.

That being said, there are plenty of people (myself included), that use these dreams to get them through the drudgery of their working day. Giving hope to those without has merit, but it's worth even more when pursued.

Changes will be slow, but imho, definite. The oldies might have inertia but I think that people under the age of thirty (having grown up with arXiv and the like) much prefer open-access publishing. Cue for Max Planck's quote:

_"A scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it."_

That said, we need to take initiative and step up to be the change we want to see.

People aren't taxed based on net worth and I've yet to see that proposed, so I'm not sure how it would work. Either way, it's orthogonal to the proposal linked by the OP.

It has lower fees than PayPal. For micropayments, you don't really need risk management. In addition to offering a lower cost option for micropayments, it enables transactions in countries not well integrated into the global economy where PayPal can't operate (e.g. Ukraine).

You're right about the forex cost.
Xero’s unique selling point is its slick and simple user interface

This worked for Mint. I am less confident it will work for Xero, even though many startups/small businesses (myself included) want an alternative to Quickbooks.

The article didn't mention this, but one of the most important selling points is not how it looks to SMBs, but whether or not banks and accountants will work with it. I remember reading somewhere that 90% of small business accountants integrate with Quickbook files or Quickbooks Online. Getting accountants to start using a new system will be a tough sell, especially if only a small number of early adopter clients are there to begin with.

While it may be possible to encourage SMBs to switch to Xero-based banks or accountants, that's a large step for some. I use a neighborhood bank for business banking services (augmented by Dwolla) and a local accountant team that is pretty sharp. Switching is not only a PITA, there's also the risk that a new bank and accountant may be lacking in other areas, even if they support Xero.
There are three answers here;

1) You identify the source of the documents (not necessarily who they refer to but who created them) and you return them.

2) You turn them into a nearby law enforcement office and get a receipt.

3) You destroy them and forgot you ever saw them.

#1 it is important to know the source, if you go by the company in the printouts and the source was an SEC auditor who was looking into the company, then returning them to the company being audited would screw up the SEC audit. In #2 it is important to get a receipt because if the documents are part of a larger problem going on you will want to be able to prove you held them for a very short time as you transferred them to the police. Anything else and whether or not you did anything with them you will be part of the investigation. And #3, they were lost in the first place, someone knows they are lost and are dealing with that. That just finishes a path they were already on. [1]

Under no circumstances do you try to profit from the discovery as that will make you a criminal in the eyes of the law. That stuff always turns out badly.

[1] Note my wife suggested that you might give them to the Taxi driver to take back to their lost and found so if the owner called in looking for them they would have them handy.
> the problem of the wealthy simply moving their wealth out

I could easily see any nation trying to implement higher taxes on the rich to also implement a wealth export tax that takes a tremendous portion of their accumulated wealth if they try to jump ship and take it overseas.

> not bringing it to the high-tax country in the first place.

This is the larger concern, but if a society can't survive without the good graces of the lucky rich, it is already their slaves.
This article suggest that MVC implies a fat server, and that using newer patterns with thin servers breaks away from MVC.

Using a thin server with a Javascript heavy app basically means keeping the Model/Controller on the server, then having Views/Controllers on the client.

So in the end, you're still with a MVC pattern, you just spread your Controller over two machines with RPC in between.
Www.Google.co.cr is down
One of the quick hacks I like to do is create a Google Spreadsheet with my goals/things-to-do across the top as column headers. As rows, I use dates, which can easily be generated by starting the first row with today's date and dragging down.

Then, I use GDoc's Conditional Formatting to color in cells...if there's anything in them, perhaps a "y", the cell turns green. Makes it very easy to see how consistent I've been...

If you're not worried about making this task into a whole chore in itself, you can always add more data in each cell and then analyze it later because, hey, it's a spreadsheet. But at the very least, you get get an easy visualization in an app you probably already use frequently and can update from just about anywhere.

I had a similar experience, with the added problem that on linux I was an xmonad user. I Persisted because I found the games I want to play are all available on OSX, which meant instead of dual booting linux + windows I could just stick with one operating system.

Development happens either in a Vagrant VM so that I can replicate the environment my server is running in (usually U12.04), or on a VM somewhere else. This has the added bonus of forcing me to be more explicit about what my minimum dev environment is, and keeping my host OS clean.
Is the error from A Serious Man that he wrote

The article makes the implication that MVC is inherently slow. It's not, in fact it can be quite fast if you use the right framework.

I'm assuming they only know that Rails is slow (which it can be, especially for a case where caching can't help much like in an API) and assume that's because of MVC and not because Rails is monolithic and Ruby-based.

Before I used Rails, I used an MVC consisting of Mongoose + Handlebars + Express in Node.js, and I regularly had pages render in under 10ms. The biggest bottleneck was consistently the communication with MongoDB, something I had very little control over.

So to conclude, stop blaming the architecture, start blaming the frameworks.
As a GNU/Linux user since '97, I've used many distributions over the years, but now I'm down to just two that I use in my day to day life.

1. Arch Linux on three laptops and one desktop all running encrypted btrfs root filesystems, and two Raspberry Pies each running their roots off of 1TB, unencrypted ext4 external drives.

2. NixOS on an Asus Eee PC 900HD netbook with an unencrypted XFS root filesystem. The functional language for the package manager and system configuration, as well as the interesting package pool symlinking, makes for a unique GNU/Linux experience. I use this for Common Lisp coding and server administration when I'm on the go.

All systems run StumpWM as their desktop environment, though the Pies are usually running headless as a simulated OpenVMS cluster, and dual torrent seed boxes.
As a more advanced examples take a look at perfect hashing. Without some randomization an attacker can produce collisions for any fast hash functions and thus degrade your hash table to the worst case possible. This was a real DoS attack vector in real web applications (see for example https://mail.python.org/pipermail/python-dev/2011-December/1... ). With a little advanced math this matter is trivial to solve.

Something else I remember was a computer graphics professor saying that the fast fourier transform was the greatest invention after the wheel.

Generally speaking you can find programming jobs where you need basically no understanding of mathematics. But computational engineering science is so much more than programming. Conversely often enough the abstract thinking that is the core of mathematics can greatly help you to tackle the more complex problems you can encounter in programming.

My wife's cousin lives this way, has for over a decade, and seems to have the kind of social network that enables this kind of living. I'm doing more than fine as a developer, and although I come from meager backgrounds came quite comfortably into having money as soon as I found employment, but do not have the kind of focus and spending discipline that living on a little requires. Perhaps everyone could cultivate an appreciation for income and really learn where they wanted to spend it. You can live on a little and have a lot, but it's very possible to have a lot and still have very little that actually matters.
Notes to self:

http://en.wikipedia.org/wiki/CAP_theorem

In theoretical computer science, the CAP theorem, also
known as Brewer's theorem, states that it is impossible
for a distributed computer system to simultaneously
provide all three of the following guarantees:[1][2]

* Consistency (all nodes see the same data at the same time)
* Availability (a guarantee that every request receives a response about whether it was successful or failed)
* Partition tolerance (the system continues to operate despite arbitrary message loss or failure of part of the system)
