For table 1 of the patent, you should just ignore the Δ values in the last column and use values from the previous column instead.

All samples are 18k gold, so the reduction in gold mass should be (and actually is) exactly the same as the reduction in total mass.

Looking at their data, for some reason there is a reduction factor of 1.25 applied to all values, except for sample F which has no reduction. My suspicion is that someone wanted to correct for the fact that 25% of 18k gold is not gold, but even then they would have needed a factor of 1/0.75 = 1.333...

I have a CS degree. I have never noticed a difference. I also don't ask. You're either smart and talented and I enjoy working with you, or you're not.
Sorry, but no. There are far more files with a given hash than just the one, if the file is longer than the hash. And having multiple hashes doesn't help until the hashes exceed the length of the file.
This. I have a degree in digital media- and I studied computer animation. And what I really learned? How to teach myself.

Theoretically this is why it has value for hoarders; it's useful. Of course, if suddenly gold was unfashionable and was only needed for plating connectors, I doubt you'd get $1200 an ounce. But it will probably stay fashionable because people like the color.

(As someone who regularly uses public transportation, I personally won't be getting a gold watch. But I see the appeal.)
Oh, you're right. I just glanced over the equation and I thought I should recommend the standard notation.

But as you stated, the cross product is clearly wrong as given by the author. There's obviously no other way than defining it with a totally antisymmetric quantity like the Levi-Civita symbol.
A trick similar to the recursive Barf compressor (add information to the filename). http://mattmahoney.net/dc/barf.html

A longer running challenge is http://www.drdobbs.com/architecture-and-design/the-enduring-... No entry fee, $100 prize, and just as unfair.

A completely serious compression challenge with serious consequences for AI and NLP: http://prize.hutter1.net/ up to 50.000$ prize money, but severe restrictions on memory and running time.

You can not beat Goldman's troll-ish challenge (certainly if the rules are retro-actively clarified in favor of the organizer). You could however try to put the challenge in limbo by creating a decompressor which bruteforces a solution, 'till some hashes match or the final heat death of the universe or the halting problem is solved, whichever comes first. Goldman will not be able to ever verify your solution, and when he does (theoretically it is not impossible), it means you win.

Or, instead of above Schrödinger's Compressor you can send a good random number generator back as your solution. If Goldman wants his file to be random, any random file should do. Why does he want exactly his own random file? Why does he want to do a diff between two random files, is he perhaps looking for order where there is none? But that's the same foolishness he accuses his participants of.

The only thing I have learnt from this and the Adria Richards nonsense is when I am hiring I will screen for radical feminism.

Too risky to hire, even if I feel my workplace shouldn't have anything that would set them off it's still too risky.
I don't think a desire to be left alone is radical. Most women desire this, they don't want strangers coming up and talking to them when they're stuck on a train/bus where there's no option to leave. A simple "hi" is the limit of social interaction you should try to push on a stranger in this situation.
The most valuable thing to me in the CS program was really being exposed to things I didn't know existed. It may not be as big an issue today with places like HN and Reddit to push you in unexpected directions, but I really benefited from being introduced to stuff I wouldn't have even thought to look at. Once the introduction was made, I was mostly self-taught because I'd dig into it out of pure interest, but that initial introduction was vital.
Finding new clients at meetups…
I’m a co-founder of a foreign software development company that builds great B2B solutions.
Me and my partner are planning to attend some SF/NYC meetups in order to meet startups that could become future clients.
Is this a good idea?
Will we find startups that need to outsource development?
That's true. The point is to secure the connection. If you wanted it, you could create a blockchain that's secured in a decentralized fashion, but upon which registrations depend on a central authority. That way you could have .edu/.gov names that are both MITM-proof and are not first-come first-serve.

Maybe take a look at Ethereum or Blockstore if you want to do that.
If you want to replace floats, what with?

Symbolic computation is way too expensive.

Fractions are good whilst they're restricted in size but are too slow at arbitrary precision and too inaccurate with numbers not centred on 1.

Fixed precision decimal floating point has numerical problems because numbers scale by too large an increment. (see footnote)

Arbitrary precision floats don't solve anything unless your problem was too little precision - with the precision of a 64 bit float this is rarely the case and 128 bits is massively more than that.

Arbitrary precision decimals don't solve anything either.

Logarithmic number systems are a good contender but almost all operations become
lossy. This is OK if you're using them as approximations - which is the common use of floats - but the fact floats are exact on the integers up to a large ceiling is useful (see Javascript) as with many other of their exactness properties.

Even better might be a symmetric level-index number system; you get the advantages of logarithmic number systems but also get immunity from overflow and underflow - the only operation that isn't closed is division by 0 and since operations can't underflow all 0s are actually 0.

If it were me implementing a new very-high level language with only weak cares about speed (eg. faster than doing it symbolically), I'd probably choose to use fixed precision fractions that fall back to symmetric level-index numbers instead of rounding. That way I'd get precise rationals (including int64s), immunity from underflow and overflow and a smoother error curve than floats.

Some people are pretty surprised to hear me criticize decimal types, but they're genuinely numerically worse than binary floating point. I've talked about this in depth here:

http://www.reddit.com/r/programming/comments/2ut00j/a_little...

and I give a rough rule-of-thumb about what type to use when here:

http://www.reddit.com/r/learnpython/comments/2wyeho/is_this_...
Most of the self-taught engineers that I've met struggle with algorithm questions, even relatively straightforward ones. Most also don't have a clear idea of things like algorithmic complexity and how to get an idea of how efficient an algorithm implementation would be. This is mainly because CS students are forced to learn this whereas self-taught programmers would need to be particularly motivated to sit down and teach themselves this, because there are no immediate practical uses for this.

The great debate of course is, how important are those skills? Many self-taught programmers I know reject the idea that these CS fundamental knowledge is important. And to their point, many self-taught programmers that I've met/hired/worked with that would be productive on day one because they have real-world knowledge and experience. Case in point, the founding engineer of the company that I work at is a college dropout, he's more than 15 years younger than me, and he's excellent. As well, I'm a self-taught programmer but came from a EE background, so I had two CS courses under my belt before I decided to pursue programming after graduating.
One other bonus: gold is mined, AFAIK, at a rate roughly comparable to the increase/production of value of everything else in society. Money is used to represent units of value in society, and inflation helps when the increase in the money supply matches economic growth. The increase in gold seems about on par with world economic growth, as noted in the aphorism that an ounce of gold can always buy a good suit or a good handgun.
Look, if you want to let people know who the bad actors are, this isn't the way. I looked at your two links - one was just plain baffling and seemed to assume I already knew the whole story, and the other was a collection of links to 404 error pages.
It's certainly not all bad. Giving people who would otherwise have no job prospects the experience of coming to work every day, getting used to the routine and socialization of a work environment and evaluating their ability to be a part of that system is valuable. Even if it only lasts a few months, it's much better than nothing. Especially given that the only alternative for most of them is a blanket rejection based on something they did years ago, often without an interview.

It would be better for all of society if programs like this were more common.

I guess this is why Gentoo is still my distro of choice after all these years.
One meme making the rounds now is that Apple will be consuming a significant fraction of world gold production for making the upper end Watches. Those calculations will now have to be recomputed, considering less will be used per watch as previously anticipated.
However, in the meantime, we have to live with "complications" like a frequent lack of support on Linux for decent console drivers in UEFI boots. For example, technically the nVidia proprietary driver doesn't support framebuffer console on UEFI boots, and if you don't get the parameters just right, you can end up in the hilarious situation of typing your full disk encryption password blind to a blank screen visibly indistinguishable from a crashed bootloader.
I haven't seen a mention of Ableton Live Packs (https://www.ableton.com/en/packs/). This is an ingenious method Ableton invented for non-developers to create new production technology (albeit, within the limits of Ableton) without knowing how to code. It has created a third-party ecosystem by giving musicians the power to create software packages. As a producer and heavy Ableton user, this is very useful and is a feature not offered by other music production programs. I feel Ableton and music production programs in general are underrated in the dev community - some of the best programmers I know work at these companies.

Currently DNSChain supports reading from blockchains. Writing is planned for a future release.

Trust is not involved "at the point of registration", unless you are referring to trusting a central authority for registering .gov's or something like that (which can be done on a blockchain as well).
Human generated semi-random binary stream
If you are a strange man trying to talk to me on my way to or from work, when I am commuting alone, you are a harasser, pure and simple. You are threatening. And you need to leave me the fuck alone.

That's hardly "over-the-top radical." If you're a young-ish woman pretty much anywhere, that strange man getting in your face on your way to work is not a nice fellow but a creep. Every woman I know has described this experience.

Also, to say that Adria Richards "[played] up her victim status to self-promote" is pretty hilarious looking at how things worked out for her.

There's no "tragedy" if men are a little worried about what they say to women. Caution is probably a good idea if your social skills need help. Systemic widespread harassment of women is the real tragedy, happening every single day.
The censorship barrier doesn't prevent Chinese art from getting out of China, it prevents Chinese art from being particularly good in the first place.

The first volume of The Three Body Problem is looking like the most successful work of Chinese fiction in English translation for the past thirty years (and that includes the books of a certain Nobel prize-winner). I chalk that up largely to the fact that it is science fiction: sci-fi fans know that the book is ultimately going to fit a familiar mold. The China-specific stuff is just special sauce, something unusual and interesting. Readers are still confident that they'll get aliens and physics and interstellar war, and they aren't disappointed. By the time they reach the third volume, and the story starts to fly off the handle, they may be disappointed.

Chinese literary fiction leaves readers confused from the start. It's often messily written, over-ambitious, blunt-toothed, and doesn't read well in English. Some of that is attributable to a general disregard of writing-as-craft in China, some of it to poor English translations, but much of it to political pressure.
This is actually really cool!

Do many/most/any municipal recycling facilities have ECS sorters? Should I tell people to throw K-cups in the recycling? I'm assuming the coffee grounds need to be removed first?
That seems simplistic. What I've seen is the jack-of-all-trades is necessary at the start. As things progress, another person - or multiple people - are assigned to each of those "trades".

But it's not just that it's specializing, it's that there's more accountability. If you're supposed to be adding function X to module Y, that's much different than "fight the hottest fire".

Sometimes people get fired because they insist on acting the way that things that started. From their viewpoint it's even reasonable: they haven't change, the position has.

Sometimes people recognize the situation and quit.

Being employee number 40 is quite a bit different than 400 or 40,000. Or number 4. Some people are able to negotiate the changes. Some bosses or CEOs can. A lot can't.
Something I have noted, maybe is just in my country:

CS Students learn from NON-developers, but CS professors.

Self-taught learn from developers (ie: in the field or from Internet).
This is the real moral of this story.

How much of a person's effectiveness in a workforce is due to environmental factors, and how much is individual?

Now, for every factor you believe is individual, is there proof, or is it an assumption?

Now even further, for every factor you still believe is individual, can you imagine a system which would solve the problem in a generic way?

Given that, would an organization that assumed systemic solutions be more successful than one that assumes individual solutions?

The answer is yes. http://en.wikipedia.org/wiki/W._Edwards_Deming
Any particular reason/extensions that makes you prefer Chrome/chromium?

I generally use FF for most everything, and reserve chromium for those few poorly designed sites that fights hard against noscript/adblock - like facebook after their move away from input-fields and to js/ajax input (They use it for stuff like changing (part of) a friends name into a mention, etc). And for youtube (mostly because the horrible ui is useless without a mouse anyway, and lets me keep youtube in a window while I browse in FF).

[ed: and occasionally for web dev/debug -- not so much because ff web dev tools aren't good -- mostly because they interact somewhat poorly with vimperator]
At least to me, that AI is actually incredibly simple. All its doing is mutating a random code snippet through a genetic algorithm. If you read the comments, the author explains that once it creates a function that it needs to complete the target program (e.g. addition func for its multiplication), it adds the function string to the list of possible mutations to add to the code snippet. It's actually a relatively simple design and I would go so far as to say genetic algorithms are probably not the way that AIs will write code in the future. Its too random and for any significant program, it would take much too many generations and the generations would be increasingly harder to fitness test as you added more and more possible functions. Still a really interesting article though. Thanks for the link.

> How do I know what the "correct" blockchain is? That I'm not dealing with a fork?

Ah, well, my friend, you should dive deep into the world of blockchain consensus, of which much has been written on.

Different blockchains use different consensus models. Namecoin and Bitcoin use the same one: proof of work via hashing. It's what prevents forks from happening (well, that and the block reward). Malicious forks can also happen via censorship, but as I explained in a previous link to a reddit comment, proof of work allows you to detect such attacks. Here it is again for your convenience:

Really, a browser is now dependent on a particular Linux kernel?

For example RHEL/CentOS 7 which was released just last year with at least a 10 year support ahead of it is now obsolete according to them because it has a kernel version 3.10...

Not that many people are on desktop versions of those OSes, and those that are will not use Chrome (for example, US govt loves them some Desktop RHEL systems, but Chrome is usually not allowed there anyway), but just highlighting how still seems a bit crazy.

If you find this story fascinating (and you should) I highly recommend reading the book written by the founder of Greyston Bakery, Bernie Glassman. It's called "Instructions to the Cook: A Zen Master's Lessons in Living a Life That Matters." It's extremely good, goes over all of the logical reasoning and humanistic basis for the decisions he made, and makes a ton of sense.

Yep, this wonderfully human organization came from a Zen master, and its foundations lie in practical Zen and all of the wonderful philosophies behind it.

Isn't it inspiring to think that the success of a business could have as much to do with the human ties and emotional connections, as it does individuals, skills, and resources? It is inspiring because it's true, and there's some core of each of us that knows that even in a corporate world.

The quality philosophies of W. Edwards Deming were equally appealing to Japanese companies, for many of the same reasons. Deming realized that the success of a company and especially the production of quality products was systemic, controllable, and inseparably human.

We ALL need to be able to learn quickly or we simply don't last. If you've been doing this for a decade or more, you're guaranteed to have that skill in abundance, regardless of your origins.

What the OP was getting at is that you get exposed to a host of different ideas and paradigms in a proper CS program. Assembly, lisp/ada/scheme/etc., C/C++/Java, graphics, computer learning, computer architecture, etc.

I learned how to code when I was ten, but I would have never exposed myself to any of those things if I didn't focus on CS in college. What does that add? Exactly what the OP said. I know what I don't know. And it's a lot.
