Hey. I just happened to check this thread and saw your response.

To answer your question, yes: the image databases were prepared with expectations of a standard Wikimedia wiki. These wikis have a standard file layout of wikipedia/wikidomain/thumb/hash0/hash01/name_of_file/thumbnail_file/; EX: wikipedia/commons/thumb/9/97/The_Earth_seen_from_Apollo_17.jpg/270px-The_Earth_seen_from_Apollo_17.jpg.

If you're using a MediaWiki installation, your files should be laid out similarly. You can change the XOWA config file to explicitly specify this WMF layout. XOWA allows the user to work directly with the WMF tarballs, so this should work for you as well. You can look at this thread for another user's attempts: https://sourceforge.net/p/xowa/discussion/general_archived/t... If you have questions, feel free to ask / post.

The other alternative is that XOWA should have the ability to read from a non-Wikimedia directory. Another user asked for this for his own private wiki: https://sourceforge.net/p/xowa/tickets/159/. In this scenario, you'd have all your files in some root directory (C:\images) and XOWA would index the directory and look-up the file by filename. You would probably need imageMagick and inkscape installed though.

Regarding your other point: I will probably centralize all the directories, instead of spreading them out between /wiki/, /file/, /user/. I had a reason for this layout, but it's causing confusion among a few users. You could always zip the files with relative paths, and instruct the users to unzip the zip. For example, the XOWA wikiquote package is one zip file: https://archive.org/details/Xowa_enwikiquote_2013-11-19_comp.... If you unzip it in the /xowa/ dir, it will automatically put all files into relevant folders

In the end, if you have a routine set up for kiwix, you're probably best sticking with it. Keep in mind that XOWA does offer some other nice features that you may / may not need. (editable wiki pages; Wikimedia Lua code). It also offers a lot customization. For example, one of the users added Mathjax to XOWA on his own. (he then proceeded to add a lot more: sorting / collapsing, wikidata skin, redlinks, etc.)

Let me know if you're interested, and I'll see what I can do to help. Otherwise, thanks for the use case scenario. It's definitely something I'll consider supporting in the future!
Brilliant! :)

AIXI is capable of anything. Give it a utility function (and a pocket universe of computium to run itself) and it will learn behavior that maximizes that utility.

That said, things like the mirror test are so wrapped up in the construction of our own brain that it really doesn't make sense to apply alien intelligences, as you'd you'd be unlikely to get a visible response for unrelated reasons. "That thing in the mirror is me, so what?" Actually that's a bit misleading - the AIXI will have no internal dialogue. It's not built that way. But give it any task, and it will learn to do that task. If that task is to recognize itself in mirrors, it will... but it will do so in a way that is markedly different from humans.
Its even worse outside the US. Most places require a (US) bank transfer. That just isn't feasible for me...I need at least a SWIFT code and would still get hit with heavy fees.
You can free up ~4500 per adult in the US "just" by redirecting the "mandatory" portion of the Social Security Administration and the Department of Agriculture (which I believe is largely food subsidies, but I could be wrong about that). Drop Medica.. and tell people to spend some of their BI on insurance if they need it and you can just about double it, with no tax increases at all.

Many functional programmers would say that "Functional Programming" is far more than just functions as first-class entities, and some would go so far as to say that you can't do proper FP in JavaScript at all.

There is plenty of room for debate over what the requirements are for doing "Functional Programming," but it is difficult to look at JavaScript and feel that it provides an excellent platform for top-notch functional programming.
Yup, I've been experimenting with CoinJar too. While I haven't actually clicked "Buy" just yet (today's Bitcoin prices seem tulip-bulb ridiculous to me), I've been impressed with everything from the website, support, deposit process, bank account verification, usability. The money showed in my CoinJar within 24 hours after depositing at the bank, ready to click buy.

They're requiring identification for sell orders from December 1 though, which could complicate things.
That's exactly the purpose of basic income. If a billionaire businessman replaces all of his workers with robots, all of his income goes directly to him. The laid off employees are now competing for the few jobs that are available which have not yet been automated, and not all of them will be able to find another job because other businesses are automating away humans too. We need a way to redistribute wealth from the billionaires who make their money off the efficiency of automation to the people who would have previously worked for them.

I kind of have an instinctive dislike of the notion of "thankfulness", like these are pure grants of fortune we shouldn't look too deeply into. The truth is that policy & other things that are actually changeable have a hell of an impact on where and who prospers. You might be "lucky" in a Rawlsian sense to be born in a wealthy area, but the fact that money has been dumped into the SF Bay area for 70 years or so, for vacuum tubes to integrated circuits to microprocessors to AI research to social media startups, has been the result of choices specific people have made.

This is true, except the polymers in question work not on a cell activity principle but on a chemical disassembly potential [1].

This would be analagous to humans evolving to the point where you could not kill one by shooting it in the head with a bullet. It could happen, people with their central nervous system in some part of the body other than the brain would survive a bullet to the head, and there are bullet to the head survivors, for whom brain structure may play a role, but it isn't a huge risk associated with shooting people in the head.

[1] "They try to mimic what the immune system does: the polymer attaches to the bacteria's membrane and then facilitates destabilization of the membrane. It falls apart, everything falls out and there's little opportunity for it to develop resistance to these polymers."

I definitely misunderstood what you said. Thanks for the clarification. I suspect your theory about what people like to see has more than a grain of truth to it.
1. Do we have to engineer how much it's being rewarded in each game?

2. What happens in the infinite case? With pacman, there are always a finite number of choices at each state.

3. If it doesn't have to be told the rules, then how does it make decisions? In theory, it may be able to learn how to play jeopardy, but it may be way too inefficient in practice. Humans don't even start with a blank state.

4. I don't think I ever consciously apply philosophical principles like ockham's razor when I problem solve or learn. It makes me a little uncomfortable that we're starting with a philosophy, rather than having the system discover things itself. I would be ok with it if there was some parallel between ockham's razor and physics (not the methodology of science).
Because they are not the same concept. Universal Artificial Intelligence is not same as Human Level Artificial intelligence.

There is no reason to assume that human intelligence is universal. Or intelligence is biased towards picking berries and avoiding bears in three dimensional world.
Would I be wrong if I said that the deviation between the parabola and the elliptical orbit trajectories is probably much smaller than the tidal effect of the earth and the sun, solar wind and other external forces on such short trajectories? And as such the elliptical model is "as wrong" as the parabolic one?

After all, a model is only as good as the precision of the results it produces...
True, caution is warranted.

But I think you missed a key point in the article. Unlike antibiotics, these polymers disintegrate. The article isn't clear on the mechanism–is it part of destroying a bacterium, decay over time or what?-but the implication is that they can be targeted to kill specific bacteria, without then escaping in to the wild to apply selection pressure on bacteria that aren't threatening somebody's life.

It's not like these researchers are unaware of drug-resistant bacteria. The whole point of the statement you quote is that adding them to cleaning agents won't breed resistant bacteria. They may be wrong, but they're not stupid.
This is great!

The straightforward solution is: For each fake title, compute its Hamming distance to every real title. Filter titles whose distances are very close to real titles.

It's O(N^2), but if you write it in Python and run it with pypy, performance may be acceptable. Maybe.

But I think this is a classic example of a Problem That Doesn't Matter. No need to spend time solving it (unless you're having fun!)
Thanks, that sheds a bit more light on it.

To me it still sounds like "I solved the problem because I formalized it." The formalization is probably novel (since he got his PhD for it) but somehow I find it difficult to believe noone else had a similar idea before (it definitely sounds familiar to me having learned about reinforcement learning, minimum description length, etc. before). I'll have to read up on it.
For those in Vancouver, we (Coinwaves) just opened a physical Bitcoin exchange in Gastown to address this problem. It seems online exchanges are still dealing with how to balance fraud-protection and customer convenience. We thought that, for now, an in-person approach made a lot of sense.

We're focusing not only about helping people purchase Bitcoins easily, but also educating them on the technology and methods of safely storing and using Bitcoin. We're also keen to impart the notion that Bitcoin is more than a mere speculative instrument, but a potentially world-changing technology.

> Allegedly, Cree has developed a white LED with up to 254 lm/W

Interesting considering that the theoretical maximum is 251 lm/W - so I wonder which law of physics they violated to do that. (Most likely it's not actually white, but reddish.)

And this time I will give you a source since this is a tiny bit harder to google http://physics.ucsd.edu/~tmurphy/papers/lumens-per-watt.pdf
Not that original intent should in any way be binding, but it's an interesting cultural shift that "single mom who, while working, and paying child care, makes less than on welfare" is now a reason why welfare is bad, when "mothers shouldn't be working" was part of what motivated welfare in the first place.

His thought process is correct, but his "pen on the Moon" model is missing vital element (that Moon is in free fall/orbiting Earth).

If Moon was hanging on a stick connected to Earth (instead of orbiting Earth) and Earth gravity forces on a pen were stronger than Moon's gravity forces, then pen would fall in Earth.

Of course you and I know that there are no such strong materials for that Earth-Moon stick, but that's yet another level of complexity that most people don't have to know about.
I'm yet to hear of anyone denying verification. I've had accounts at BTC-E, CampBX, Bitstamp, and Coinbase to name a few. Haven't had a single issue getting verified anywhere and most took less than a week.
It's not true that it's hard. For Europeans, buying from Bitstamp.net is not harder than your typical online store experience. However, there seems to be some kind of problem with verifications currently, which is a separate problem. (I guess they are rate-limiting for some reason)
Wal-Mart, McDonalds and other similar large low-wage paying corporations should not be able to use government welfare in what effectively part of their compensation to employees.

Think about what would happen if they weren't able to do this. Prices would go up and who would this hurt the most? Their customers. Who are their customers, generally? Poor people.
Oh, it's not good at killing, yet. That's reassuring.
This article sort of blurs what privacy is, conflating it with data analysis. As long as companies anonymize their analysis, then your privacy is kept. If you don't want to share something like an event that happened to you, you don't need to share it on an online social network. That choice is still yours. So is the choice to even use those services. Those companies in question are not releasing the data to the public, and I'm reasonably certain that those doing the data analysis are anonymizing the data when analyzing it (having a positive identity on a person is useless from a statistical standpoint anyway).

Privacy is being able to do things privately without prying eyes. Reading email is a private action. Going to the bathroom is (usually) private. Data harvesting doesn't prevent you from doing these things without anyone identifying who you are, unless it's a government entity doing so, in which case that entity is in the business of positively identifying individuals.
Given my experience with MongoDB over the last three years, I'm having a lot of trouble figuring out how they will use it for matching, since I've found the search and indexing pretty slow.

Perhaps they can leverage the auto sharding capabilities to fan out queries better? That's the only advantage I found with MongoDB over other DB systems.
Yes, exactly. The only problem is, in practice, it's so hard to get rid of those things, that we may end up with basic income AND various forms of welfare and that would not be good

If it were 1:10-20 then these people would have already voted in basic income platforms into government.

I also suspect that a lot of these guys have been trained for manual work that is, regardless of basic income, being moved overseas and automated. The work is going/gone.

Edit: Also, I would highly respect any manual labourer who would stay in their job even though they were sure of their income. I think that is a useful currency too.
The difference is I'm quite confident in our industry being able to help people protect their privacy now that it's a mainstream issue. The markets reacting. I'm a strong believer in decentralized web services replacing monolithic ones like GMail. These companies may even get pressure from new information privacy laws about data retention/sharing similar to HEPA and health records.

Whereas I'm completely pessimistic about the possibility of state-surveillance being repelled by policy or technology.

But agreed right now, infosec/privacy is a class war. Only those with sufficient knowledge and resources can live a truly private life.

Why do you think it is relevant what you do consciously? The only things that you do consciously are those things which your brain is ill-equipped to do. The vast majority of your thinking processes are subconscious, as are the principles that drive your conscious thinking. And I guarantee you, Ockham's razor is in there whether you realize it or not. When things get complicated do you purposefully look for a simpler solution? When trying to understand an unknown situation, do you start with something simple and ad complexity as needed? Ockham's razor.

> I would be ok with it if there was some parallel between ockham's razor and physics.

... there's not?

EDIT: As an AI researcher, I'd be more interested in creating an artificial scientist than "artificial science." So what makes the scientist work? Ockham's razor is at the foundation of that.
You are looking for a distance metric on strings. If d(s1, s2) = 0, where s1 and s2 are strings, then they are equivalent.

"Łódź" may be the same as "Lodz" to you in the same way that "komputor" may be the same as "computer" to a Russian speaker. To someone else the names "Anderson" and "Andersson" are equivalent. Now you see the problem -- exact matching is futile and you should use fuzzy matching instead, like normalized Levenshtein distance, and rank the results based on similarity.

Even that is not enough if you want to support non-Latin alphabets because they have different ideas about what a character is but it should get you started.
