> However, Wu's method needs lookup tables for the whole color (hyper)cube,

You're talking about the 1991 method. The 1992 paper I cited explicitly claims as one of its advantages that it does not require lookup tables (and thus avoids the usual step of pre-quantizing down to 5 bit color to get a reasonably-sized table).

Your two big wins sound an awful lot like "K-means". I'd believe they are responsible for the bulk of the improvement (they're also the bulk of the computation), but they mean you don't have axis-aligned partitioning anymore, which was my point.

The problem is that K-means is notoriously sensitive to the initial clustering. For unsupervised learning, I'd want to do as good a job there as possible, and applying PCA means you are picking the split direction that exactly minimizes variance in the orthogonal directions. Random restarts are also a nice way to escape local minima, but are even more expensive computationally.
Toka is a chatroom-based community.

It is based on the following 3 principles:
1.) With 2 billion people connected to the Internet, meeting people online with similar interests should totally be easier
2.) The social taboo against making friends online is outdated
3.) Chatrooms allow people to connect with others in a way that’s not possible through content-driven sites like Facebook or Twitter.

Facebook, Twitter, and Reddit are driven mostly by user-generated content. Users post things like statuses, photos, and comments – social interaction is then derived from this activity.

However, we think that there is too much emphasis on content rather than on the social interaction behind it. A karma system encourages this – the “like” or “upvote” functions have effectively turned the act of posting into a popularity contest, since the people who accrue the most amount of likes or upvotes are the ones deemed as popular. This leaves little room for actually building relationships.

So what does it mean to be “social” on the internet? Is being social on the internet even a desirable thing? We think that being social on the internet means exactly the same as it’d mean in real life – making new friends and keeping up with the friends you already have. Over time, you might drift apart from some friends, or you might grow closer to others. But considering how many people are on the internet now, it’s crazy that there isn’t a system to make the social process easier.

in fact it is related to outsourcing. in the past outsourcing processing involved shipping drives of data overseas. The risk and schedule hit were big, the offshore companies had crap hardware that usually cost a lot more than it cost in the US. That quieted down for a while. The new cloud stuff got these people interested again in processing outsourcing, only now the data is shipped to google.amazon/whoever and the outsource employees use the cloud vms to run the processing. I wonder how long before this mini trend starts slowing down when they finally figure out that management overhead and poor communication is in most cases the main problem with outsourcing.

Because housing instability creates social harm. Tech salaries would (probably!) keep pace with the demand for non-rent controlled San Francisco housing, but teachers, cops, firefighters -- let alone retirees -- incomes won't likewise scale. Folks like that will be rapidly priced out of living anywhere for longer than the length of a minimal-term lease.

A stable community is a thing not much valued by (young and transient) tech workers, though I would argue that even they derive some benefit from living near folks who make less money than they do.

Rent control doesn't create utopia -- and this article describes some of its acknowledged problems -- but neither would abolishing it be free of consequence.

Like most things in life, it's a trade-off. Don't overlook one side of the exchange.

Try Facebook's Hack if you want all the nice stuff of PHP and modern language features.

PHP still beats the pants out of just about any other language out there in the ease of use department if you want to build websites and is fairly simple to learn. Once people pick up PHP, then they usually start exploring other languages that are more involved and strict.

All this PHP hate is really discouraging to beginners.

This is exactly my though process as a software developer. I work remotely so I dont speak out loud (most of time), but i think it helps too. It is similar to when you have been debugging something for hours and you figure the solution right away when you start explaining the problem to a coworker.
Thank you for sharing your points: for me this is actually quite an endorsement of gogs (But then, I'm not looking for an alternative to gitlab).

> * There is no Debian package which would be nice.

True. AFAIK there aren't any packages in Debian that depend on go/golang yet, not even in sid. That doesn't mean one can't make out-of-band debs, of course, but gogs unfortunately isn't alone here. Does anyone know of any util/tool/package in go (other than golang) that's packaged for Debian?

> * It's written in a language that most Devs / Ops can't contribute to or bug fix.

As opposed to what? I'd think being able to patch something in go would be within the grasp of most Ops, and also most devs?

I wish they would just hurry up and IPO so I could invest in them. Anyone who thinks Pinterest isn't worth much, or it's just a scrapbook website, clearly doesn't have a woman in their life. My wife (and really every woman I know) use Pinterest all the time WITH THE INTENT TO PURCHASE things. Planning weddings, and nurseries, and houses, and remodeling, and and and...

That is why Google is valuable. People go there with intent to buy things. Facebook has learned how to make money. Twitter has learned how to make money. Pinterest has a much much easier road than either of those did. The people investing in this round will absolutely make money.

Not true at all, though publishing is an important step. Understanding what is going on is important.

Doing a 'calibration' dry run (literal dry run!) with toast with one side marked with an X instead of butter, 7 out of 10 trials read one way. Adam remarked "This isn't random enough - it should be 5!".

The Mythbuster guys get 11/10 for curiosity and the spirit of investigation, but 4/10 for scientific rigour :)

It is hard to say as all these companies are the middle man and they charge their base fees and connect you with different skill level people; depends who you get connected with. I've been burned twice so be very careful spending your money. Never put up front money, get stuff in writing, talk to people on the phone and ask for proof that what they already built? See if they measure up to your standards. If money is not issue, go with well known brands/people, if it is then ask the developers for some referrals.

That should be pretty easy with parse transforms, here is an example for embedding JSON:

As another comment suggests (https://news.ycombinator.com/item?id=9215580), this would allow you to keep everything as a data structure until the last minute.

In regards to business logic, I think you just need to be strict when writing your application with the idea of what a 'view' is. Although React may seem like you are violating separation of concerns, in reality view logic and templates are already tightly coupled.
Did it? Even if you get actionable information from torture - a very big 'if' mind you - you're also going to get a bunch of specious bullshit that you'll waste time following up. If you arrive at the truth at all, which again is not likely, it will have been after being misled. You will be, by any objective measure, dumber for doing torture, even if you eventually arrive at the truth.

I try to act in such a way that I am made more intelligent, and I believe that governments probably should too (in particular the parts of government that we refer to as motherfucking intelligence agencies). But, to each, his own.
They're doing the "growing" on a membrane at the bottom of the tank, instead of layer by layer at the top of the tank.

That should let them print really quickly and precisely, even compared to the SLA printers you link.

The reason it hasn't been possible in the past is that the polymerization process requires oxygen, which has only previously been available from the air over the liquid resin. Their system has some "secret sauce" for getting it to the bottom of the vat.

Can this be extrapolated out to other systems such as MySQL or Vertica?
so this is SLA+?

speed seems to be a factor - i think SLA printers are limited by resin curing time under UV light.

perhaps this is more a resin technology than a printer technology.

they do keep mentioning oxygen - but it's not clear why
Smooth curved surfaces have been a limiting factor for 3d printing in regards to optics. It sounds like this could be used for either directly printing some lenses or printing molds that could be used to create lenses depending on their level of precision. This would be awesome.
Clinkle did raise 25 million as well, nevertheless this looks cool and hope it is affordable.
React Nexus basically recursively traverses the react component tree and calls getNexusBindings on each component (recreating what react does natively with its lifecycle methods).

However, this incurs the cost of instantiating each component in the tree twice. Once for traversing asynchronously for data, again for React.renderToString or React.render

This would cause slower initial page loads for SPAs. Otherwise, very cool implementation.

>PHP still beats the pants out of just about any other language out there in the ease of use department..

This is not true. Why is it easier than, say, Ruby

>Once people pick up PHP, then they usually start exploring other languages..

But since they are already brainwashed from PHP use, it prevents them from seeing the value of doing thing the proper way, and might see the process as contrived. This is the most dangerous aspect of using PHP. It blocks your learning and understanding. It pulls you down and keep it there.

A good example is the use of PHP arrays. It is a combination of different data structures like list, dictionaries, sets etc. But because it is a combination, you wont be able to use it as a list, or a dictionary or as a set to the fullest extent. And you will be so used to using this for every situation that you might be put off by lack of similar data structures in other languages, and blocks you from seeing the value of using the right one for a particular situation.

So I request every one who is passionate about programming and wants a career in programming to keep away from the php language and community as much as possible.
You are. Using UV to cure photo-sensitive resin isn't the innovation, it's using the oxygen permeable membrane.

If you look at the Form 1 printer or the B9Creator, there's a mechanical step between every layer where it needs to actuate the platform in order to loosen the resin from the projection window, so it can build the next layer. In the Form 1, it peels the print off, and the B9Creator slides a window. (look for videos on youtube.)

In both instances, the amount of time spent actuating the mechanical part adds up, and results in a significant amount of time spent in the print actuating the plate. What the oxygen membrane allows us to do is to skip that step between every layer, and simply keep shining a continuous changing image slice of the object as we're pulling the object out of the resin.

Not only does this have the advantage of speeding up prints by orders of magnitude, in materials, the grain of the object influences the type of thing you can built. If you print a stress holding object with the grain orientated in the wrong direction, the part will fail very readily. This way, we have greater design freedom, without worrying about grain direction.
See the paper in Science released online just now:
http://www.sciencemag.org/content/early/2015/03/16/science.a...

It will apparently be the cover story. (Does this count as Sequoia breaking Science's embargo?):
https://twitter.com/sequoia/status/577651625545748480

From the abstract:
"...feature resolution below 100 micrometers. ... complex solid parts can be drawn out of the resin at rates of hundreds of millimeters per hour."

Key novel feature is the oxygen-permeable, UV-transmitting membrane at the bottom of the tank that creates a thin (down to 20um) inhibited 'dead zone' where the resin can't polymerize. They project the image for the current layer up through the membrane and the dead zone, so the build layer is actually within the tank. This means they can just draw the part up continuously from the top, with no stepping or processing needed after each layer. The thickness of the effective build layer can be controlled by adding a UV light-absorbing dye to the resin, which allows them to optimize for different print speeds.

I think we underestimate how much contact there was between East and West long ago.

One contributing factor to this was that the Ottomans closed the silk road to Europeans.

"Contact" between Europe and Asia was already a fairly tenuous link, where very few people actually made the journey or even talked to people who had (ignoring for the moment wars).

The closing of the silk road made it seem even more remote.

This led to European nations seeking sea-routes to Asia, which ironically led to greater knowledge of the East (as people in Western Europe started hearing stories first hand, instead of third hand via traders who traded with caravan traders).

> Doesn't change anything. It is still shit.

To be fair there is no perfect language ,especially in dynamic/weakly typed ones. PHP "grew organically", was successful because at the time it came , it was easy enough for hobbyists and non programmers.

It's still the cheapest way to develop web apps and for those who like java patterns they can still upgrade to these because of its class system.
While I wish Ruby or Python would be more popular, they are not as easy to use as PHP(while ironicaly it is easier to go further faster with rails for instance than bare bone PHP),they are not as cheap to deploy too.

There is a natural progression between learning HTML and then adding some server-side behavior , that wasn't met by other solutions (while java has JSP, forced OO makes it too complicated for beginners)

Nevertheless, PHP has excellent libraries , extensions that even some "hotter" languages do not have , I think when people start projects they don't just look at the language but also the ecosystem.
This is awesome.!!

I think the last commit on LUSH was from ~2012 (I could be wrong). It also doesn't come with Lexical scope, or CLOS support (again I could be wrong). It is very impressive though.
"Ease of use" often leads to "impossible to maintain". Strictness is one of the best features of any language in the long term, and it rarely results in much more thinking or typing. If you don't know what type you want something to be, you're not designing your code right. Why not let the compiler know while you're at it?
Something I'm coming to learn: for any bureaucratic system, those who are most capable of taking advantage of the system are the privileged. Every time we try to arrange a benefit for the poor, infirmed, disadvantaged, disabled, we create a tool for the more privileged to advance themselves. The poor hit a rough spot and they can't hold onto their homes – only the well off can hold their property for decades. Even rent control: who is most able to ward off an eviction? Who can access the legal system? Who can mount their own defense? Who can see the machinations of their own landlord and work in advance to counter? At every turn, when we make a rule, we give a tool to those who can work with rules; if those people were at one time not privileged, they are privileged now, and have been for some time.

I don't live in SF so I can't speak to that, but in the Boston area it caused rents to go up. No one wants to buy a house when home prices are falling month-over-month. A lot of people looked around and decided they didn't want to get locked in and risk being underwater. A lot no longer qualified for standard mortgages. Many people simply lost their jobs, so home ownership was out of the question. Plus the glut of foreclosures. But people still need a place to live, so the demand for rental units shot up even as home prices and mortgage rates were falling.
