"Every successful project which is linked in any way to semantic web, would have been successful without the semantic web."

I was thinking many times of it. For most of the time it is true, but not always. I still can find few good examples. Look at dbpedia. It may look messy, but there is vast amount of data there, that is taken advantage of by many projects (also commercial). While i can imagine making a database with the same data, it is the "linked data" initiative that gave it such possibilities.

I agree that there were huge loads of money spent on it, and many projects simply didn't deliver what was promised. But anyway, does research always succeeds in 100% of the cases?
You are right meant to write NTriples not N3 but editing on the phone is such a disaster. N3 adds a rule language next to the data description over RDF. XML disallows a few things that are possible in turtle but in practical terms there are very few cases where that could make a possible difference, e.g. who has a \beep code point in their normal text.

OWL is powerfull but hard like all description logics, they ar e tools that very very few developers really master. Yet can be used for very interesting things.

Validation is not the goal of OWL and is therefore not well supported. ShACL or whatever comes out of W3C for schema descriptions and constraints will be easier and more performant for this use case.

On the last para: yes, yes and yes. Very mature stack with a lot of competition and innovation.

Cheers!
One problem with this approach is that most people consider "life enrichment" to be courses that are biased towards their own political viewpoint. Conservatives want students to have a basis in the history, literature and philosophy of Western Civilization. Liberals want to teach students to think "critically", i.e. to view Western Civilization through the lens of oppression and racism (and all other ism's).
Here are the ones I'm thinking about quite a bit when I think about the long-term viability of our species or society-as-we-know-it.

(1) Food security. Not many people talk about the fragile system that supports our ability to stay nourished. At the same time, "nourishment" is relative -- we're getting fatter, it's unclear whether industrial agriculture is sustainable, etc.

(2) Social inequality, lack of social mobility, etc. This is something that will have a major impact on our way of life in the coming decades if it continues. Look at Europe and the US to see how fragile and unstable our societies are (and how much worse it's getting).

(3) AI. OK, everyone is talking about it, but I don't worry about it in the context of AI destroying the world, but rather how problem #2 above and #3 mean fewer jobs, more inequality, etc. At this rate, we will not become a society where our subservient AI-robot-slaves do our work for us while every human is enlightened and self-actualized. Instead, automation will drive the cost of labour down and thus cause more inequality in the decades to come. Of course people will continue working -- this defines them, and whatever meagre salary they make is necessary to survive.

(4) Our inability as a species to accept that galactic space exploration will probably be painful, slow, and require generations of space travlers to sacrifice their egos and lives to enable their ancestors to arrive at the destination they set out for. Maybe I'm pessimistic but there won't be "warp speed" and if that's the case, then space travel and galactic colonization will require re-defining what it means to be a human race -- it'll be more akin (and more extreme) to the way colonists visited the Americas -- they gave up their families, communication with the "Old World", etc. to start a new life. Now imagine these same colonists would set off but accept that they would die on the journey, as would their children, and their grandchildren, and only their grand-children would arrive at the destination to maybe prosper, or maybe die... We need to accept that this might be what galactic colonization looks like. I don't think we're ready for this as a race/species/society.

I'm not so sure. There used to be plenty of walk-throughs published in gaming magazines as far back as I can remember. While I don't recall any for RTS' (Dune II wasn't that hard, IMHO) -- I do seem to recall eg: Shadow of the Beast, Another World, Flashback and Chaos Engine having some big guide specials in the 90s.

Sure, it's easier to just go and look stuff up now -- but I don't really think that has much to do with the decline. After all, if someone wants to ruin their fun by following a manual -- why would they spend money on the game in the first place?
Recently I had some related ideas, although from a completely different background. Here is what I would have done differently:

1) Implement other storages. Although databases are a natural part of web applications, a direct storage in files and/or directories may be justified. Also, for most applications the full dataset fits easily in the RAM on modern systems.

2) Keep full history. Or provide for this possibility at least. Adding history features to classic database models becomes cumbersome quickly, but for a simple schema it may be provided directly by the framework. This provides for a great audit log if something went wrong. Probably to be disabled if really unwanted and/or storage size is an issue.

Regarding the different background: Although most people want graph databases if they don't want to enforce a certain schema, my desire is the exact opposite. I want more constraints, data integrity as much as possible. I want more than can be easily reached even in PostgreSQL with user-defined functions, such as constraints across foreign keys. So a separate checker is needed, and I believe graph structure with plain links provide a good, simple base to define a constraints framework upon it.
house_arrest used to allow direct access to the documents and container of any app. It's used by the Xcode "installed applications" list, to allow you to download and upload container contents. In 8.3 they changed it to only allow VendDocuments access to apps which actually have document sharing enabled in their Info.plist (and VendContainer access for ad-hoc provisioned apps, iirc).

Backup is done via a completely separate service.

iOS releases do tend to arbitrarily change the security policy of these services, but it's not clear that "Rootless" is anything more than business as usual. Guess we'll find out Monday.
It's not wrong. Making something free means paying for it in a transparent fashion.

Bernie Sanders is not talking about changing the institutional structure of college such that it somehow has no cost to provide. He is talking about the government paying that cost on behalf of students.

I agree with free education, by the way. We currently spend our budgets on much less useful things. But let's be honest about what it means and how it works.
Ask HN: Single repo vs. repo for each service?
Recently I’ve been working with having the entire codebase in a single repo way and it’s not really been a good experience. Every time someone modifies code in a separate module, I have to recompile/generate sources to fix the compilation errors. Not to mention compiling takes a lot of time as well. Some of the points in favor of the single codebase approach I’ve heard is that you don’t have to worry about versioning. Since everyone has to pull in the same changes, everyone has access to the same thrift sources as well.

I’m mostly accustomed to having separate repository for each service. Personally, I think it makes it more manageable. It goes hand in hand with the SOA approach. A bad commit in another service doesn’t affect you.

Yet, I’ve seen the single codebase method in bunch of orgs. I believe Google does this as well? I'm curious to know which one is more common. What are the pros/cons that have factored into choosing one over another?
Ray Kurzweil’s Mind-Boggling Predictions for the Next 25 Years
Sure they help build community, but paradigms change. There might be a better way. If a 1/3 of middle class income wasn't stolen and wasted bombing the manufactured enemy of the week or propping up corrupt banks, it's possible that even more would be spent on community. People like to give, but put under financial pressure, it's the first thing to stop. The real problem is this idea that it's ok to use violence to take someone elses property. It's a fundamental structural flaw, an asymmetry that undermines the rule of law by making it legal to steal if you have the right title.

Sono lesbica – come dirlo ai miei genitori
Whilst Marcinko is no doubt a legend, reading Rogue Warrior should be mitigated by following it up by Gormly's "Combat Swimmer". Gormly inherited the unit after Marcinko had some issues with his chain of command (whether justified or not, is up to you to decide - we all know Marcinkos) and has his own (or the Navy's?) opinions about the man. Like Kurosawa (Rashomon), it is often better to know more than one point of view...

A more balanced account of what it is like to run these kind of units can be found in Beckwith's own "Delta Force" (also consider "The Mission, The Men and Me" by Blaber and "Inside Delta Force" by Haney).

The ultimate such unit may have been the Rhodesian Selous Scouts, and whilst Pamwe Chete is out of most people's price range, there are numerous excellent books on the subject. Whether or not you agree with Rhodesian politics, the tiny unit who pulled off Operation Eland and allegedly caused the majority of enemy casualties in the Rhodesian Bush Wars is worth reading about.

In the same spirit as Rogue Warrior, check out "The Phantom Major" which chronicles Sir David Stirling's efforts to create what became the SAS. "Mad Mike" Calvert's various books pick up where Stirling allegedly left (some, such as Stiff in "See you in November", claim that Watchman International amongst others was a front for the MI6's black ops, so Stirling never really "retired") and also has some nice stuff about Orde Wingate, another interesting leader (both in results, and as a person) who unfortunately did not survive Burma.

On a separate note, in "19 with a bullet", Korff claims that the South African 1 Recce's selection procedure was 8 weeks of walking through the bush with no food except a weekly tin of beans and two slices of toast to share between two, and no weapons or kit. The unit generally sounded very interesting and I'd be grateful if anybody knows of any good books or writings, I personally have not found much.

Thanks for replying. Have you tried this at scale? What is the performance like when you have thousands of records? Have you looked into traversals? I ask these things because I tried to build a product using MySQL that should had used a proper graph db and I ran into a lot of issues. I think now that I'm a bit wiser, sql may be able to do similar things, but I haven't tried.

edit: the model layer is the most impressive part about this. You should consider making it a stand-alone package.
> It should be about general life enrichment

This is a view that rich people can afford to hold. Poor or middle class people cannot reasonably afford to pay four years of opportunity cost, plus tuition, for "general life enrichment."

The Ireland control serves well here too. Are Irish medical doctors, and indeed all European doctors, less "enriched" than American ones? I'm very skeptical of this idea, but if you could propose some metric that would allow us to evaluate the question, that might be helpful.
Yes, I didn't look for the rock star/rockstar, but you're right, if people feel the need to mention words such as rockstar/ninja, it's already a problem.

Ask HN: Would it be possible to get feedback on our project?
I am a chemist by profession, but after visiting SF I was amazed by the startup culture and since my return from SF, I have been working on the project “RepairShift” with a friend of mine who is an iOS developer.

We followed a simple guideline: build a product to solve a problem or simplify the existing process.

We are in beta mode and were wondering if we could get feedback?

Any input would be greatly helpful.

Maybe these superhumans, rather than being evil will finally understand this and help the rest of humanity.

Has this ever happened before? Any time any group of hominids has had an edge over another that they shared space with, it's pretty much resulted in subjugation or extermination. We're really, really bad at tolerating those who are nearly the same.

What does "ten terabytes of computing power" mean?
I think I can express my opinion simply now. Thank you. -

"Practical" pure math appears to be based on formalism rather than intuitionism. Because foundations and therefore intuition does not hold formalism back, these practitioners drift further away from being able to communicate their metaphors to whose who rely on intuition; such as biologists.

- And this is my opinion.
It looks like the site is a false-positive for some automated spam-filter.

I think it depends on your goals and needs. Where do you want the biz to be in 6 months, a year, three years? What skill sets do you need? As a developer, I've really benefited from bringing on a really good marketing head as a minor partner. My skills lack in that area, and with two people things get done faster. Just having someone else to work with day to day who is really invested is a huge accelerating force. Advisors aren't the same thing. If you can find someone you know has the skills you want and is go-getter enough to be a partner in a startup, that might be the best way to go. Nice site! Good luck.
1) Grab a console from eBay, fleamarket, ...

2) Get a few games along with it

3) Hook it up

4) Play old games on/with real hardware

5) Fun! (sorry, no profit here ;) )

Really, nothing beats the experience playing those old games on their respective hardware. You're missing out if you're using an emulator (though more power & kudos to the devs!).

Only thing i'm using an emulator for is trying the more expensive games first if i even like them, since retro-gaming kinda exploded and the prices of used games with it :/

The experience I had was that, while it was theoretically possible to make cljx+figwheel/weasel/piggieback+cljs all run happily together, in practice it didn't work for me.

With boot, everything is both pretty easy to understand and conceptually very familiar. It's a middleware based build system, and that maps really well to a lot of the other things I've learned building clojure web apps.
Maybe it's because I live far outside the Bay Area, in Europe, so I don' get the culture, but the whole guru/ninja nomenclature makes me nervous. Maybe it's my low self-esteem kicking in, but I find it hard to associate with things like Ruby-ninja or DevOps kung-fu when I just don't feel like a ninja, and not sure will I ever. What's wrong with regular names? Can you imagine an civil engineering mage title? :)
I strongly disagree. Mostly because the semantic web is very, very useful in the life sciences. And over the next 5 years will save more money being wasted in this field than was ever spend on grants for the semantic web tech. Not just on the academic side but also on the big pharma side.

For the rest I would say this holds true for to much of any CS research e.g.: Grid, Cloud, P2P and GPU compute. Looking at the vast sums spend on this the practical benefits are from outside the academic labs. I.e. all those other buzzwords that are used to justify grants.

OWL reasoning at least standardised the format of many logical constructs and allowed for competitive improvements. Now you can at least change your prover while maintaining your axioms. So you get something like StarDog which is vastly better than the Pellet you are probably familiar with.
Plenty of us are working on nuclear fusion, but funding keeps getting cut year after year. It's simply not as sexy and doesn't get as much attention as the cosmological kinds of questions.
What do you mean by "not generally a good idea"? In the past I've had little cause to complain about using XML fields to store and search semi-structured data in MS SQL Server.

I have read that it doesn't scale out as nicely as document stores do, and knowing SQL Server I don't have trouble believing that. Personally I'm a very long way away from needing to worry about scale out[1] in the applications I use a DBMS for, though, so that's never really kept me up at night.

Word I've heard on the street is that the story's similar for PostgreSQL.

You think if not for semantic web, the dbpedia folks would've just shrugged and said "oh well, if only someone had invented a way for us to share knowledge"?

It's like saying J.K. Rowling couldn't have written Harry Potter if not for Bloomsbury Publishing's in-house style rules.

That's semantic web for you. Dbpedia is a project whose value is 99.9999999999% comprised of its content, 0.00000000001% comprised of semantic web scaffolding, and semantic web comes along and claims full credit for the entire thing.

That should be "multiple small maps". In English, adjectives are generally placed in this order,

1. Quantity
2. Value/Opinion
3. Size
4. Temperature
5. Age
6. Shape
7. Color
8. Origin
9. Material

http://www.edufind.com/english-grammar/ordering-multiple-adj...

Hence, "multiple" (quantity, 1) precedes "small" (size, 3).
Different company. We just bought their domain name.
I beg to differ. Being a semantic web researcher myself, I can tell you that it has produced many relevant theories and artifacts that do help influence the world in positive ways. Here's a few to get you started:

http://linkeddatafragments.org/ - allows to query several "semantic web" datasets at runtime by issuing several concurrent HTTP requests

http://www.rdfhdt.org/ - allows to store graph-like data in a very compressed format that is queryable directly in memory

http://events.linkeddata.org/ldow2015/papers/ldow2015_paper_... - (shameless plug) allows you to query and browse semantic datasets (hosted by different people on different servers) on the web using keywords

The fact that they're not useful to you does not make the entire field useless.
Dynamic web apps in the first "bubble" era were generally either perl/cgi or ASP (without the .NET suffix, obviously). Javascript was used, but only for small things like required field validations. Databases would be SQL Server or Oracle or Sybase, typically. PHP and MySQL was also used. Servers were mostly either Sun or Microsoft (for ASP), though there was some Linux.

The main difference from today was that almost all dynamic content was generated server-side (of course we do still see that today also, but it's not "trendy"). Layouts were table-based and yes, styles were almost always in-line and not in separate stylesheets. Very little JavaScript, because it was common for browsers to not support it, there were significant quirky differences between browsers, and the CPU speeds of the day meant you couldn't do anything substantial with it anyway. If it was used, it was again typically in-line in an "onblur" or "onsubmit" handler.

Security of web apps at the time was laughable by today's standards. SSL had a significant impact on server performance and was mostly limited to use on the login page, if it was used at all. SQL injection was only beginning to be understood by most developers, many (most?) sites used SQL queries made with unescaped concatenated strings and were vulnerable.

If they were really on board with Microsoft technologies, they might have abstracted their logic into business objects likely written in VB6, running in a COM layer in Microsoft Transaction Server, which called stored procedures in SQL Server. Or they might have used Java and JSP and servlets

Almost nobody had broadband unless they worked at a university or tech company. Dial-up was the norm elsewhere so page assets had to be pretty minimal. Many people had screens that were 640x480 so most websites designed for that.

I still see a lot of code in languages like PHP that is quite similar to what was being written in 2000.
