I think there are still quite a few C and C++ programmers out there. To me this is a great example of why it is better software engineering to write a server in something like Node.js. Because rather than having a million code bases with potential memory leaks like this one, there is just the Node code. In ordinary JavaScript code its impossible to cause a problem just that.
Amen. That is the biggest thing I'll miss as a result of him stepping down. They'd really be screwing up their conference by taking him off the docket.
I didn't get that impression, "all of the final 5 teams met the eligibility requirements specified in the Official Rules". They did mention that they are doing a more "in-depth" review, but they should have been immediately disqualified by the fact that it's clearly stated you must start after October 25th.
In theory this stuff is archived 'somewhere' but the realities of archived video is such that often it is just not accessible. The library of congress is supposed to have a copy of 'every' movie, and everything that is copyrighted, but due to various cut-outs that just is not so.
Yeah didn't notice the lack of doc comments. That is nice to have for a library.
How about you provide a scenario an average person can use? Like, say, County Market accepting bitcoin?

I can't afford a sub-orbital tour in USD, let alone bitcoin. Is there any leading supermarket that accepts bitcoin? Literally allowing me to use bitcoin to put food on the table?
Someone else asked this too, check out my answer there.
I think what made me think of it in the first place was the representation of the largest known primes (http://primes.utm.edu/largest.html#biggest)

The current largest prime is (2^57885161)-1, which is 17,425,170 digits, yet can be represented with much less, obviously.

Maybe adding exponents would help. aX^n + b, perhaps?
Walmart Labs has been doing lots of javascript for awhile. I believe they will probably release something similar soon as well.

I've been running an extremely simple Node application on 0.10.18 for a while now and it has a very gradual memory leak. My code is just a few dozen lines, and it all seems pretty innocent. I am also using Hapi, so I thought maybe Hapi has a leak in it somewhere. Now I wonder if I have the same leak as Walmart here. I just now upgraded to 0.10.22 and am curious to see where I end up. If the leak goes away then hot damn, I got lucky :)
It might be foolhardy to assume that BTC transactions are anonymous, but that doesn't mean that it wouldn't be EXTREMELY EXTREMELY EXTREMELY difficult to figure out who was involved.

Litecoin, for example, is designed to be mined on more commodity CPUs than GPUs, and has an algorithm specifically designed to deter faster GPU processing.

Heh. That was their goal, but it didn't work. Then they redefined Litecoin as GPU-friendly and ASIC-hard. Do we believe they're right this time?

Well those are certainly improvements, but they're basically hacks around the fact that flying is now slower than it was in the past.

The biggest impediment to speed today is the dreaded 'Cost Index' which nearly all airlines now implement. I think Boeing have a different term, but it's the same idea; the crew are given a target CI which they punch into the flight management computer and which then determines the Mach number according to the cost-saving target.

Flying from Belfast to London is now timetabled at 20 minutes longer than in 1973, regardless of the extra standing-in-line at either end.
From a brief look, they load all of the content initially, and only use checkboxes to filter it when displaying – a click on a checkbox updates the set of criteria and calls a function to re-populate the DOM with new elements.

They seem to be using Jade templating language to generate the HTML for each course, but it can be done with jquery as well.

If you're looking at techniques for actually loading the content dynamically from the server, check out http://api.jquery.com/jQuery.ajax/ and related methods.

If you're looking for some sort of magic that keeps your JS objects and HTML DOM in sync, check out http://knockoutjs.com/ for example.
Are they still at 600?
Neither underscore nor lodash use a for loop. Both use the native Object.keys when available. underscore uses native Array#forEach and lodash uses a while loop. So only lodash forEach is actually faster.

lodash is the only one to be performance focused. underscore always uses the native methods when possible.
That's kind of nitpicky. My point was that if there is a hackathon with a highly desirable prize, and you know about it in advance, there is a direct incentive for you to spend time between the time you learn of the hack and the time when the hack officially begins working on ideas, designs, business strategy, and even code, and that that effect is the reason that it's not a good idea, or in the spirit of hacking, to offer high stakes prizes in hackathon style situations.

Where did the high resolution sonar images in the article come from?

This discovery was pretty unconfirmed unless there is some new source I am missing in the article, besides photobucket.
That's a huge problem with most javascript libs I hack. No Js doc means wasting a lot of time trying to figure out what is the dev intent. Or they just removed all docs from their scripts ,seems more likely.
Even a "super random" 6-character alphanumeric password is not very secure. A brute force algorithm can try the entire space of 6-character strings very quickly. Hopefully they rate-limit login attempts!

That's my point. He hasn't offered any conclusive proof yet the existence of the article is structured in a way that suggests there is something untoward to be discovered. Are we to assume that he wrote the article with the hope we'd read it and come away without any bias whatsoever?

The inclusion of the filters, despite them showing no significant manipulation, sets up the narrative that we are on our way to discovering how the pictures were faked.

If this were someone's Instagram pictures of their lunch that would be fine but we're talking about a respected photographer documenting a major news event. If there is something fake about the pictures then, yes, that needs to be uncovered. But not by amateur internet sleuths Googling pictures of blood to compare splatter patterns.
Nothing here really adds up.

1. The earliest pyramids in mesoamerica currently known are about half the age claimed in the BBC article. There are older pyramids in South America (specifically Brazil), but still nothing as old as is claimed here.

2. The linked page says this complex may have been submerged after the last ice-age, but that would actually double the age of the site!

3. The depth of the site (reported on the BBC link) is 650 meters below current sea level, but only 183 meters on the wordpress link. However, at peak glaciation during the last ice age, sea levels were only about 130 meters lower than they are today. If we don't use the BBC article's numbers (could be a metric-imperial conversion error) that still leaves over 50 meters difference, which is rather a lot of subsidence given the geology of the region!

4. The BBC article is over a decade old, but no new findings have been reported in that time. Whether it's 650 or 183 meters deep, somebody would have sent a sub down for a better look by now if it actually existed.

Shenanigans! My guess is that this is the blogspam driven resurrection of an old hoax.

I should have said "general solicitation" meaning "general audience". People who don't know what they're getting themselves into.

If you set up an event like "demo day" at Y-Combinator where investors and founders meet and discuss equity and terms that's perfectly legal. That's NOT general solicitation. Everyone there knows what they're getting themselves into. No one can be "tricked" into investing like the general public can.

With a large number of courses and pictures, you'd probably want to use ajax to fetch the course info every time a box is ticked.

Alternatively, you could use a framework like Angular.js: http://angularjs.org/

Hope that helps.
I always thought recording all TV and indexing the captions would be a cool project. The Google Books case may set a precedent to legalize such a project.
You have to do your research.

Peter Blodget in the PandoDaily talk was pretty pessimistic about it. See: pandodaily.com/2013/11/18/blodget-and-the-rarified-air-around-bitcoin/

I, for one, am somewhat pessimistic about it since it doesn't tie to a national currency. Noble cause, but naîve, IMO.

Yeah, when I saw they released the Hapi[1] framework for Node several months ago my initial reaction was "is Walmart Labs part of THE Walmart??"

Actually ran this on Chrome/V8 and the native method was faster. And as someone else wrote: lodash/underscore should normally fall back to the native methods if available.

As for bind - funny that you mention that as a good alternative to using self/closure. Because while it is convenient and powerful, it's also slower than using self/closure.

I don't want to pretend that for either `[].forEach` or `bind` the differences in speed are (in most cases) really that relevant, I just found your argumentation a little confusing here. As for bind vs. closure-self I wouldn't say that either is really better than the other. Both are perfectly fine options. The former is a pretty heavy solution (since it's basically using a special case of partial application) and can be confusing (e.g. calling `a.b()` can have weird behavior even when the implementation of b is known). The latter is less powerful but a little more explicit imho - you really see the this-scope expansion and it's not hidden away. Both solutions obviously can't protect you from "flock of seagull style nested function code" but as you wrote: that's not a problem of the way someones does this-binding, it's a problem with the design.
The real problem occurs when you want to buy something that costs X, and all the addresses you control have fewer than X coins. You have to join the coins from multiple addresses within the wallet, and this joining provides very strong evidence that the same user controls all these addresses. So if one address is known to belong to a particular user, we now know (more or less) that all addresses belong to that user.

This joining means that even if you've been super careful to never link address A to you because you've done sketchy things with A, if at some point in the future (even distant future) you join A with another address that the someone CAN track, they now know you own A.

I think whatever performance cost might exist with Object.keys and Array#forEach vs loops is outweighed in most cases by a pretty significant increase in readability. There are exceptions, of course, but I think the performance card gets played too often in cases where the difference is negligible.

As for self = this, I tend to agree that it's kind of gross in most cases. It's not something I use very often. But unless you're willing to say that you're never going to use anonymous functions, the reality is that sometimes it's useful.
I'm mad at myself for not having balls/faith in Bitcoin ~1 year ago. The price was around $10 per BTC and I debated if I should buy 1 coin per month just in case the price went up, but I didn't... I could have had a ton of money now if I just had got the balls...
Zombo.com's parody is strangely timeless.
I started Googling the Picasso "principle" about it being a lifetime to know how to do it, but it turned into Googling this one instead. Found a snippet, "Karl Steinmetz (German-born, U.S citizen), the well known electrical engineer who worked out many details of a.c. theory and was responsible largely for the adoption of a.c. for commercial use, was once called in by the General Electric Company to examine a poorly performing transformer. After a few minutes, Steinmetz marked an x on the transformer core and said, “It will work if you take off the turns from this x to the end.” The prescription worked well, and Steinmetz later sent G.E. a bill for his service of $10,000. The company official thought the bill excessive and asked for the itemization. Steinmetz then sent them a more detailed bill: For putting x on transformer core : $1; for knowing where to put the x: $9999." It's funny that in today's world, both Picasso and Steinmetz take "minutes" to do this, but in perhaps earlier tellings, it took hours for Picasso to do his work and days for Steinmetz: http://edisontechcenter.org/CharlesProteusSteinmetz.html
"supposed to have a copy ... everything that is copyrighted"

Many things have a copyright restriction on reproduction. These happen automatically upon creation. The LoC does not get a copy of these. (For example, it doesn't get a copy of internal proprietary company documentation, even though those are covered under copyright.)

There are additional legal advantages to registering a copyright. These are part of the public record, and the LoC may have up to two copies of these registered documents.

However, it can decide to not keep any copies. Quoting from http://www.loc.gov/loc/lcib/9709/acquire.html:

The Library usually rejects individual company sales manuals, advertisements, coloring books, elementary and high school textbooks (except in U.S. history), instructors' manuals, student workbooks and self-published books except for genealogies, local histories and other publications of special interest. ... The Library collects materials in all subjects, except technical agriculture and clinical medicine, which are kept by the National Agricultural Library and the National Library of Medicine.

So, your text is more correctly written as "The Library of Congress may have up to two copies of every movie or other thing with a registered copyright, but due to various cut-outs that just is not so."

Thus, there's no reason to assume this stuff is archived anywhere.
The performance hit of using .bind() instead of `self = this` is much larger than .forEach() vs loop. Pick your side :)

Respected photographers have been duped before, and the post addresses this. I think jontas' assertion may be accurate.

I'm sure there are valid criticisms of his analysis, but I'm not quite sure calling Dr. Krawetz an "amateur internet sleuth" is fair if his biographical posting is in fact true [1]. On the other hand, if his qualifications are exaggerated, then his findings are assuredly suspect.

People still buy silver as an investment, I hesitate to say "as money" ; although I told in Mexico you can buy and sell silver in many banks (I don't know the details however).

In the USA, gold was demonetized (1933) before silver (1965) in the currency when used in the USA. The dollar was convertible into gold internationally however.

The international gold window was closed by Nixon in 1971.

A few things.

1. Are the smaller package sizes reflected in any of the inflation numbers you cite? I am asking an honest question here.
http://finance.yahoo.com/news/looking-for-inflation--it%E2%8...

2. What do you think about this website? Is he a crank? If so, why? It's common knowledge that the CPI definitions change regularly. http://www.shadowstats.org/

3. How do you feel about geometric weighting? It tends to underestimate inflation. I've done some math here: https://news.ycombinator.com/item?id=4781794

4. Economics is the study of human action, because without humans making decisions and acting there would be no money, no industry, no nothing. People tend to estimate inflation at a higher rate than economists calculate it. Who is more likely to be wrong? https://news.ycombinator.com/item?id=4777899

5. What do you think about the "hedonic" adjustments in the CPI? If you look at the BLS' website they try and say "this stuff is all perfectly legitimate" but inadvertently acknowledge that the definition of inflation is changing. If there were no hedonic adjustments in the 60s and inflation was 0-5% range let's say that was "baseline" inflation. Now there are hedonic adjustments and inflation is in the same range. If those adjustments can reduce inflation then we might be experiencing more price increases now than they did in the 60's but it's simply under-reported. http://www.bls.gov/cpi/cpiqa.htm

Ultimately I believe strongly in some of what Nassim Nicholas Taleb talks about in his writings when it comes to what can be known and not-known. If a coin toss comes up heads 99 times in a row any person capable of exercising some thought would realize that there's something wrong.

I can't put my finger on the exact problem with CPI calculations but I can tell you that where my dad was able to support a family on a single income, and his dad was able to do so as well, I can say with confidence that it would be very difficult for me to do that today. We all had/have engineering degrees and in fact I'm the most educated; I've got a masters degree and they only had bachelors. And I'm in electrical and computer engineering; arguably quite a good business to be in. Why is there such disparity there? How can the official numbers not reflect the difference?
Is that internal proprietary company documentation considered just a trade secret or a trade secret and also protected by copyright?
As much as I recognize and appreciate the limitations of chess, it pains me physically to see the strategic depth of it compared to something like Starcraft. It's not close by orders of magnitude.

Wow, thanks for the link! I would never have thought that the joke was based on an actual incident.

For those who are wondering about the Picasso principle, it's based on a story about a woman who asked Picasso why he charged $5000 for a painting, when it only took him seconds to paint it. He replied, "Madam, it took my entire life!".
I was talking about 25 onsite conversations leading to 10 offers and maybe 3-5 acceptances. In order to have 25 onsite conversations companies likely have to talk to 125-150+ total individuals via phone/email/networking events. That's at the low end once all the processes are dialed in.

I agree that companies have to be respectful of candidates' time. People do talk to their friends before they engage with companies or accept offers and word can get around fast if companies mistreat candidates (as it should).
Oh wow, same guy? That's a pretty conclusive debunking of his claims...
