The interesting part about PNG is that since it uses the DEFLATE algorithm, and only applies compression per row/line, with no awareness of relationships between lines, is that in most cases, the effective compression is nearly the same as if you took apart each row of uncompressed pixels as an individual image, and took all those separate images and put them in a zip file.

Disregarding the cruft of headers and other file format overhead, there would be a direct relationship between the size of a PNG image, and the raw, uncompressed row-level data zipped up and handled in a similar way.

China's largest businesses are extremely state-connected, and it's hard to imagine any successful business in China not being deeply connected to the government. I basically consider those entities as extensions of the Chinese state.

I don't know if China would look the same if they allowed western companies to just swoop in to extend monopolies.
You're looking at a power law. Just like Cities in a country follow a power distribution of population (I just doubled checked that rule for UK and they indeed follow an almost perfect power distribution) so "Start up" areas will also follow a power distribution - but due to the extreme mobility of start-up founders and capital that will be applied globally not nationally.

Silicon Valley being the pre-eminent location for start-ups is a positive feedback loop which puts it at the extreme tip of the power distribution.

Not a single mention of security.
Rutter said the initial focus would be to agree on an underlying architecture, but it had not yet been decided whether that would be underpinned by bitcoin’s blockchain or another one, such as one being built by Ethereum, which offers more features than the original bitcoin technology.

Once that has been agreed on, Rutter said, the first use of the technology might be the issuance of commercial paper on the blockchain.

Can anyone speculate on why they would begin to issue commercial paper?

> Why do scientific "papers" insist of using PDF when HTML would be a much better choice

Almost all journals do offer both HTML and PDF versions of their articles. The main advantage of PDF is that it appears exactly the same as the printed article in a journal, and is easy to print.

A PDF also combines the whole article into a single file that can be easily imported into reference management software.

> as it supports linking to references

So does PDF (easily generated in LaTeX using the hyperref package), though a given PDF file may or may not actually include links. For example, the ACS journals offer a 'PDF' and 'PDF w/ Links' download for every article.

> dynamic media (better graphs)

This is a fair point, but enhanced/interactive figures could be on a separate figures-only web page.

> meta keywords

PDF does support metadata, including Author, Title and Keywords. In LaTeX this can set using pdfinfo: http://www.howtotex.com/tips-tricks/adding-pdf-metadata-in-l...

I'm not sure what you mean. The PDF of any paper will contain serchable text (except for old papers produced by scanning archived copies).
As long as they start their own blockchain I think it would be interesting. Otherwise it's a bit of a hassle to use the current blockchain, I would use the same codebase and not start from scratch though since the code's been tried and tested, and as they said you can send messages through bitcoin as well already.

That is correct, we are using the functionality similar to HBase. We pull in the HBase BlockCache library with some tweaks to make it work for our scenario. Note that data is never overwritten and HFiles are immutable. So the cache automatically, gets evicted/populated as HFiles are opened and closed. That said, there is a possibility to use more performant formats like rocksdb etc. in the future (the format is pluggable). Or even still use HFiles and have them loaded into some kind of specialized in memory data structure etc.

Many EU countries got startups during the mass consumption revolution. US however is the only country to have not missed the micro revolution. US got micro startups in 1975, 1983, 1995 and so on. Hard to beat 40 years later as no one has experience nor tech money. Its not that we dont have hackers in EU, its that we dont have Paul Graham. I dont think this - tech experience and tech money - is easily relocatable as it is stated in the article.
Maybe. There were LISP machines developed that did all that natively. The metal was a high-level language of incredible power with good implementations doing low-cost abstractions via macros. Almost all investment went to the other architectures for sheer price/performance and backward compatibility. Reliability, maintenance, integration of 3rd party code, security, etc weren't a concern at all. Now they are: even mainstream is tossing much of the old stuff where possible. Your same argument might have worked in reverse had several billion dollars of engineering gone into hardware designed to implement ML, Scheme, Haskell, and so on.

Besides, there's little debate to be had on what's the best model: all of these are built on hardware that's interacting functional programs (combinatorial logic) and finite state machines (sequential logic). How they're combined varies on a chip by chip basis. Underneath, though, everything boils down to a careful combination of functional and semi-functional programming implemented in silicon. Except analog which is purely functional. ;)

Note: This brings out another angle whereby we use tens of thousands to billions of circuits running concurrently in a functional way to simulate a sequential, imperative machine that does way less in a clock cycle. This is why porting the algorithms onto FPGA's almost always has significant speed-up unless the imperative machine is insanely optimized (i.e. Intel/AMD/IBM). It's also why even prototypes like SHard produce efficient, better-than-generic hardware from functional language specifications of algorithms. Maybe we should just go functional all the way and invest money into CPU's which do that with utmost efficiency, eh?

This is irrelevant to the fact that a very large market and testing ground exists today among the Chinese-speaking and Chinese-cultural population, both inside and outside China.

Most successful startups in post-2000 China are largely privately owned. While they are indeed subject to regulatory constraints, needing to work together with the government is largely a constraint to survive, not a reason for success. Their successes have very little to do with the government and much more to do with the market, rising economy, and better infrastructure (e.g. education, venture capital, incubators, startup "hotspot" cities, etc.) for startups to build upon, as well as the sudden explosion of a middle class that can afford the various things these new startups are offering.

I'd say a large part can be attributed to the fact that China and USA both have similar market sizes and both countries are each reasonably homogeneous in culture compared to, say, Europe.

I guess it's similar to walking away from the TV. However, DVR providers attempted to use technology to automatically skip ads and there was a huge backlash.

I'm working on a project that involves lot's of web crawling. I'm not technical at all (I'm hiring freelancers).

While I do have access to great general technology related advice, this post is bound to bring people well versed in crawling.

My question is: in terms of crawling speed (and I know this is dependent of several factors) what's a decent amount of pages a good crawler could do per day?

The crawler I built is doing about 120K pages per day which to our initial needs is not bad at all, but wonder if in the crawling world this is peanuts or a decent chunk of pages?

From the article: “I think that these technologies will probably be post-trade,” he said. “I think savings are in the settlement side, in post-trade, in issuance, but not in exchange trading or OTC trading any time in the near future.” He added that R3 will soon announce a few more banks joining the project."

That makes sense. This replaces the need for a single trusted clearinghouse with a redundant, shared ledger. Confirmation occurs when a majority of the banks have put a new transaction into a block. Because the parties are not anonymous and new ones can only be added by mutual agreement, it's like a "proof of stake" system. There's no need for "mining".

Bitcoin has done a good job of validating a blockchain system as being secure against attack. No one has broken it yet. None of this, of course, does anything for Bitcoin as a currency/investment.

That's not quite what I mean... Sure, banks ideally should do such things... I'm just saying given they centuries long track records... I still don't trust any of them.

"Secure" to banks means, only secure enough for them... I just believe that the future (think 25 years, minimum) is that every single activity of every single person will be tracked in detail to a level which we can't even understand now.

Wait until all your activity is then predicted and compared to actual to refine the tracking. And banks will be doing HFT based on the actual and projected minute-by-minute actions of billions of people...

Speed doesn't matter, it's all about the wavefront. The radar equation provides a rough guide here, in that the power of the signal drops off at a ratio proportional to the distance squared, the r^2 dependency. I have no idea what the rest of the terms in that equation would be, though, as I have only ever done the calculations for RF in air.
Something like Uber could never have come out of Europe. A large company that is breaking the law while competing with regulated taxis and remaining unregulated themselves? That would never fly in the EU,

This is a feature, not a bug.

We do tend to regulate some areas more in Europe than the US, but from various on-line discussions about Uber in recent months, I have come to the conclusion that the original problem they are trying to solve is much worse in the US than the EU.

Meanwhile, I have no problem with requiring any service competing with regular taxis to be held to the same standards in terms of vehicle maintenance, insurance, checks on drivers, standardised metered pricing so passengers know what to expect, etc. Being able to beat the incumbent because you broke the law and took shortcuts that could affect safety is not impressive.

Also, I don't know where you got the idea that in the EU you need to prove what you're doing is not harmful or illegal before you can do it, but you're completely wrong.
Here's the press release (pdf): http://static1.squarespace.com/static/55f73743e4b051cfcc0b02...

This sounds exciting. My gut reaction was that the banks aren't going to use it for actually transferring money, but as a way to notarize transactions that will be acknowledged by the whole group. It does sound like a cool way to verify everything going on among a network of players.

And there's a lot of weird hate towards bank on HN. I know they're not great, but it's really not helping the conversation to just say things like "woooo banks are scary!"

It's a shared ledger system! So, really no need to have it be bitcoin. It does make sense. It'll be great to see the confused looks on lawyer's faces when they try to lobby to change the blockchain history.

I don't think that's true.

So first of all this whole article is essentially about the "filters" that are used to encode the data more efficiently based on the surrounding data, before it's passed to deflate. Basically compute some kind of a delta from the pixel compared to the pixel up of it, left of it, or a combination of the two, with the deltas generally compressing better than the raw data would have. That's already a big difference to compressing each row separately.

Second, the deflate compression does not happen individually for each row. It happens individually for each IDAT block, but those blocks can be of fairly arbitrary size. Using a separate IDAT block for each row would seem very odd. (Can you even use filters in that case, or does the state reset with each new block?)
So you're saying that Google could come in and compete? If you're a foreign business in China, even if you are a Taiwanese business, if you don't have proper government relations, you'll find that business applications take so much longer.

And that you have little hope with Chinese law before a Chinese judge and a favored Chinese company. It is a hostile atmosphere to even Chinese-speaking countries -- if you are not connected to the government.

I'm saying it's very hard to discuss market forces from "free" market principles when the most successful companies in China shall be deeply connected to government. You wouldn't say Gazprom is a product of the Russian economic environment. Nor is Alibaba and Baidu.
