First of all, the "market distorting regulation" you mention that causes Goldman Sachs to shuffle aluminum around is not a government regulation, it is an industry standard set by the London Metal Exchange. The article suggests that there is a conflict of interest. The Exchange get's 1% of the storage costs, and the same companies that benefit from this rule are the ones that control the Exchange. This is a classic case of monopoly and collusion, not of overreaching government rules a regulation.

The "rules and regulations" that are proposed in the article are simply to reinstate the principle that bankers should not be traders. What's happening is that Goldman Sachs has physical assets in the aluminum market, and also the ability to speculate on that market. From the article: "By controlling warehouses, pipelines and ports, banks gain valuable market intelligence, investment analysts say. That, in turn, can give them an edge when trading commodities. In the stock market, such an arrangement might be seen as a conflict of interest — or even insider trading. But in the commodities market, it is perfectly legal."

How are the "little guys" hurt by preventing insider trading? Do you plan on founding a startup that speculates on commodities and also controls those commodities? Do you think that such a startup should exist or would be capable of bootstrapping without hundreds of billions in initial capital? Startups are only able to exist in the cracks created when we take the hammer to the monopolies.
> Is that not enough?

It's not clear cut like that.

Farming nowadays produce crops with 2/3 of the vitamins you used to get, due to exhausted soil [1]. Wild salmon has 33% more Omega-3 than the ones grown in tanks [2].

Even if you manage a 100% fresh/unprocessed food (unlikely nowadays), you still ingest less vitamins than your parents did.

The key question is whether the LME is free to change these rules...

They did change them, that's where the 3,000 number came from, did you even read this story?

...if the participants are free to use another exchange or start a competing one...

I don't see how that's likely to help. First of all, the metal suppliers have an incentive to use Goldman's warehouses and thus the Goldman-controlled exchange, since Goldman's paying them a kickback. Secondly, if enough metal is going through the LME, that sets the de-facto market price and you'd be daft to sell your Al for less than that, wouldn't you?
If you eliminate mining, energy and banking Canada has essentially no internationally relevant big companies whatsoever. RIM and Bombardier are the only ones I see on the TSX 60 and the former is in its death throes. The future looks grim for Canadians.

The version I have implemented, PCRE, is fairly common. It's good starting ground. Goal is to add more flavor-specific support, but thats in the future.

Thanks for the kind words!
I don't see anything wrong with that. I'm excited about all the possibilities of crowdfunding, including market validation and supplementary capital.
You should be able to support tabs open in incognito windows as well if users grant your extension incognito access.
Perhaps the response would be similar if he had a design for two headed baby clothes, or superhero outfits.

There is this notion of the 'uncanny valley' where a rendering/expression of a human gets too close to the real thing. There is a similar space in design where dissonance between what is possible and what is shown jars the senses.

Escher used this to great effect, creating scenes that you eyes initially perceived as 'normal' but began to sense a 'wrongness' or 'otherness' which as you looked more closely became apparent.

This would have worked better as an exercise if he had done an advertising type pitch for a tri-corder or what ever the Stargate equivalent is. But by using the next generation of a product that is already out there and known for its design, and adding in features which are currently science fiction (and physically impossible [1]) the designer causes the brain to go "urrrk?" and the whole thing collapses.

[1] For example, iPhones use a touch screen based on capacitance. Graphene is a conductor. A transparent graphene cover would shield the phone from being able to see any change in electric field (it would, at best, be diffuse across the conductor) and render the touch screen inoperable. Try this fun experiment, put a piece of paper over an iPad and watch your gestures go right "thru" it, put a piece of foil over your ipad, and note how you can do anything.
If you're willing, would you please explain the bankruptcy connection? That's kinda cool!
I don't understand why so many designers attempt to push the limits of material science while clearly being almost entirely ignorant of it. For example, carbon fiber composites do bend. You can make springs out of them. Also, if you could figure out how to manufacture graphene at a scale large enough to use them on iphone screens you'd probably win the Nobel.

You can't push the boundary of what's possible without already understanding the physics and engineering of the existing boundary. Otherwise you're just another kid with a pretend jetpack made out of 2 liter soda bottles. It's fun, and perhaps praiseworthy for a kid... but as an adult you look a bit silly claiming the design is something real.
Ask HN: Sync SQLite With SQL Server (Merge Replication)
I spent a couple months develop a Sync Engine which sync data at Table/Row level between SQLite and SQL Server (2008+) over HTTP for iOS and Android, and it works with Xamarin. But the project failed to go ahead, now the sync engine seems to be a waste. I have no idea how to take this to next level. I am looking for help.

Let me explain why I built this sync engine in the first place? I worked on Window Mobile (WM) platform for a long long time, the solution (Field Sale Force app) I built requires app to be fully functional even there is no internet connection as the user needs to complete tasks in various places. I used Merge Replication to do the sync at database level for WM application for more than 500 devices. WM is dead by now, everyone wants to use iPad to be next platform. The problem I found there is virtually no good sync engine runs on iOS device can replace merge replication. After done lots of researches, I decide to write my own sync engine. In addition, I rewrote the Xamarin Field Server app to prove that the sync engine does work.

The some benefits of the Sync Engine I can think of right now.

1) Write great offline enterprise app.
2) Increase Developer Productivity as the developer only need to focus on CRUD operation, the sync engine takes care of the data synchronization.
systemd manages cgroups on systemd based system. The systems that do not use systemd can implement their own cgroup managers. The kernel makes no assumptions on what manager you use on userspace. Other managers could also reimplement the systemd dbus API for managing the cgroups.
That's a particularly odd configuration of flash chips, though. That's why you don't see 96GB SSDs very often. Generally, they're found in powers of two.
Evolving Monetization
Technology (the product) can be decentralized. But the generation of ideas that create the products is a separate thing from the product itself. Many would say there is a geographic aspect to the generation of ideas... that people, for some reason, need to be in proximity to each other. When bright people work together they produce much more interesting things than when working in isolation from each other. And from observation, it also seems that bright people seek each other out. This isn't to say SV is great or doesn't have its issues, but it seems to attract the brightest people from around the world (and possibly 'parasites' as you mention, as well).

I don't think most places like Canada want to replicate SV... just the part about creating large successful tech companies. The article suggests this might be helped by allowing people to actually get and stay there. It's not really about 'centralized technology' but more about creating a culture where people from around the world can come together and make these things happen.
You're right. Besides soil depletion and not having access to mineral water, a big source of Magnesium and Iodine deficiencies are the lack of access to seafood.
My only suggestion for choosing technology would be to pick
lightweight things that are known to work and see a lot of
use outside your company, or else be prepared to become the
“primary contributor" to the project.

This should be put on a header for anyone considering the sexy new thing to come out, be it Node.js, MongoDB or the bazillion JS frameworks etc... Not saying you should avoid these altogether; just be prepared to iron your own wrinkles if you ever intend to become popular.

not sure why you got down votes. some of the examples, i agree with you, aren't pleasing. quite a few are.

it's been a great tool to show beginners, imo. it clearly demonstrates the effect/power of CSS on the aesthetics of a site. the fact that some examples are "so ugly" can be used to convey that impact...
I think you mentioning that you'll personally oversee and QA their project has a big impact on how positive the news is received. In fact, that's a great approach!
systemd-logind doesn't use code from consolekit. It has been written from scratch. ConsoleKit itself has been unmaintained for a long time.
I feel like the statistics are misleading with respect to the total pool that you're drawing out of. Of course, if you have a school like UC Berkeley that has 25k undergrads, you're going to have more funding than a school like Princeton with 5k undergrads. Per-capita stats would be nice to see.

Also, maybe schools with MBA programs might need to be compared separately. Princeton doesn't have one, and seems to lack somewhat in terms of on campus non-technical founders.
Once you experience it, it's awesome and people will talk about it.

Why is it so flatly awesome? My experience was: overpriced room (overpriced because the high airbnb fees get passed on to the person who stays), annoying extra "cleaning/deposit" fees that don't get refunded (and you're not notified that they didn't get refunded), and a quasi-too-personal system of booking where half the listings are by weirdos ("RENT A ROOM IN MAH CAMPER ON THE STREET!") you can't filter out or fake listings nobody responds to.

It's squarely not in my "things that make me happy" column.
I mean when your company fails, you are not personally liable to pay off the debt.

In some countries, this is not the case, and it creates a big legal barrier for being entrepreneurial.
AIREAL - Disney's haptic feedback device
I'm not the OP, but I'm assuming they're referring to the common philosophy that if you make the cost of failure too high, people will stop trying.

In the context of bankruptcy, this means that laws that are heavily punitive towards bankruptcies, and where declaring bankruptcy threatens the basics of your entire life, people become more risk-averse.
I don't understand how the number of people who viewed this yesterday goes up. Shouldn't that be a fixed metric? If it's just a demo, maybe some better number to demo would be better.
The colorizer does most of the grunt work, it tokenizes the regex and colors it properly. The explainer then basically just loops over those tokens and explain them. It's a bit hacked together as it works right now though; but it seems to do the trick. The explainer does some additional error-checking which the colorizer doesn't have enough resources to do as well. Anything in particular you want to know?
CHAR/NCHAR are fixed length, VARCHAR/NVARCHAR are dynamic length... Usually the biggest restrictions to varchar/nvarchar are indexing limits.. generally my indexed fields for n/varchar will be 100 (email, name, etc) non-indexed, xml hashes, json will be NVARCHAR(MAX)/NTEXT when they aren't indexed.
That's nice. But I kinda like the multi tab feature. It was the biggest thing to happen to browsers before HTML5. Usually when I google something I open the first 4-5 pages that look relevant so I can quickly scan their content. Even on HN I open 10+ tabs with the stories that seem interesting and then start reading them. But I'm sure there will be users who need this. Good job.
Yeah, well he is not an industrial designer, doesn’t advertise himself as one and doesn’t sell his industrial design skills. Which he doesn’t have. Doesn’t even claim to have. Not even a little bit.

He is a fucking graphic designer and that’s exactly how you should judge this.

I didn't even know there were actual sequential GUIDs until I just googled for them. Thanks!

Seems they are mostly just like autoincrement integers with the random GUID data following. I guess you still have the storage constraints, but now you at least can order them easily.
I assume you meant billion, not million.
You're so hostile that you kick the ball into your own net. My question was whether LME was free to "change" the rule by abolishing it, or whether this was related to an underlying CFTC compliance issue. Because trying to increase the stringency of the rule did nothing:

Martin Abbott, the head of the exchange, said at the time
that he did not believe that the warehouse delays were
causing the problem. But the group tried to quiet the furor
by imposing new regulations that doubled the amount of
metal that the warehouses are required to ship each day —
from 1,500 tons to 3,000 tons. But few metal traders or
manufacturers believed that the move would settle the
issue.

This does not argue in favor of your tacit position that we just need more rules, or more men with guns to enforce them.
Suure, and its not the first time either!

I think his point could have been made clearer, but he's really just saying that there will often be a mutable natural key that is captured in the modelled data, and that it makes sense to enforced constraints over that key if you know that the constraints exist.

Whats the case history for demanding source code? I remember airplane crash victims asking for the source code for the plane computer, people demanding source code for voting machines, and others demanding source code for medical instruments in malpractice suits.

Did anyone of those actually get the court to force disclosure of source code, in what capacity/scope, and did anyone win a legal case because the software was found as faulty after source code was disclosed and inspected?
Everpix sounds like a very good service. Almost too good to be true kind. I'll definitely give it try. I just wonder if I'm auto-posting from one service to others will I end up storing multiple copies within Everpix?
Ah yes. Corrected!
> I dunno, my negative reaction to it isn't that the designer is breaking the limits of feasible materials and mechanical engineering...it's that, given no such limits, the designer proceeds to create something not terribly original or interesting.

I agree with this wholeheartedly.

My secondary negative reaction to this, though, is that I think there's a certain conceit in putting this design together and calling it the "iPhone 6". Whatever merits these drawings might have, they could be showcased just as well by making up an arbitrary new name for it and calling it an evolution in smartphone design in general — rather than hijack Apple's branding just to draw attention.

No you don't. Not sure about MySQL but Oracle supports returning generated keys as part of an insertion[1]. An additional round trip is not required as it comes back in the "success" response of the insert itself.

I disagree with the cheap / free and then 'capture extra value' model, purely because I personally hate games that do that. That's not to say that it doesn't make good business sense, just that I wouldn't enjoy making those kinds of games. If it was my livelihood perhaps I'd feel differently, but I'm very happy being in a situation where I can make exactly what I want, for the market I want! (full disclosure: I'm the guy that wrote the blog post).
There are a lot of unethical spiders out there....
systemd is hardly monolithic as it is build of over 80 binaries. A normal system with systemd runs at least four processes: systemd (PID1), systemd-udev, systemd-journald and systemd-logind. There's various smaller services that are run on startup and other occasions. Then there are many configration utilities like timedatectl (systemd-timedated), hostnamectl (systemd-hostnamed) and localectl (systemd-localed).
I saw a bright lightbulb above my head for a moment: a paid service for $99 per month (or whatever!) and we will daily/weekly monitor if any of your properties/tenants are listed on BnB. Optional service for extra buck: we will mail them C&D letter (with Realtor logo on it, of course) to violators. I can see a brilliant marketing campaign and can imagine many Realtors signing up!

Does something like that already exist?
Except a big portion of the oil is owned by foreign companies. So, it's not like we are ripping all the benefits either.
I do not completely agree with the usage of the term, as Locust economies are economies like in China. When they do not have enough resources of themselves, they will swarm and find these abroad and cause lots of issues. For example with the needed infant formula (milk powder, esp after the milk problems in China with melanine) they will swarm to foreign countries and buy these in massive amounts and cause shortages in the country of origin. This even concerns building materials (steel), energy resources (oil), etc etc.

The milk powder issue for example happened in the Netherlands and in many other countries; partly caused by producers not knowing how to deal with this, but also by people within the country shipping large amounts (seen as smuggling), selling on Taobao.com. Just google for "Dutch milk powder China". This is just one of the examples... There are now even export restrictions between Hong Kong and China for the amount of cans you can take across the border. Just look at some of the pictures on http://badcanto.wordpress.com/2012/07/08/hong-kong-netizens-... related to this.

Note: relating to the article I believe the vision is narrow since it only talks about Groupon... Also, his point is not a survival means as the grasshopper/locust metaphor would indicate.
I kind of agree with you, but being a UK citizen I was watching the UK app store by default. Bearing in mind that I was hoping to make a few hundred quid / dollars being in the top 100 in any chart was a result! :)
Yes but I see no point in using fixed length string fields. Double so for the examples the article gives (first and last names). All the times I've encountered them has been with legacy systems ands it's been a universal pain.

All your front end code ends up doing TRIM(...) to clean them up the extra padding. Modern RDBMSs all handle variable length fields efficiently so it's a waste of programmer time to have to deal with CHAR/NCHAR fields.
This is HN. Anything goes in the name of growing a startup!

I am sure with higher infant mortality and bigger families there were massive cost savings in gender neutral clothes for small children. We have our first girl due. I went to the local semi-quality big chain store and a stack of nice pink onesies were on the rack for under $5 (AUD) each. I got them to the self-checkout and found they were all marked down to around $3 which is less than a large cup of coffee around here. So although we will reuse our huge supply of robot, dinosaur and truck outfits, colour coding her gender in public for the benefit of strangers isn't going to be a huge financial burden.

More pissed off with the pink toy aisles. I can buy my boys a semi-decent quality kitchen to play Gordon Ramsey in for $110 AUD on special at the same store available in pastel pink only (all the kitchens stuff has pictures of girls on it and is pink - all designed by or for Americans I guess). A similar gender neutral product in the same store is available by online order only for nearly twice the price. So the boys have a pink kitchen because fuck it - boys cook and women haven't been trapped in a kitchen for decades.
