I bet you half the problem is the software being specified in a synchronous and not asynchronous manner.

If a flow chart is expressed synchronously, it immediately bottlenecks around the slow backend systems. e.g. check the applicant has 4 kids, and if that checks out, present them with these options.

I attribute some of these problems to inadequate advances in today's mainstream programming languages.

For instance, if futures/promises were common parlance in programming, some of these bottlenecks would have been identified earlier.

I once read an interesting essay on what future programming languages could work on. One of the interesting ideas is a language that allows programmers to implement undo/redo easily. Recently there was a blog post about fuzzy computing, where a function is able to return approximate values when it is busy. The Knight Capital incident teaches us that if we architected our monitoring systems the same was as intrusion systems are done, we could have stopped activity when suspicious incidents occur outside the normal operating range. There was another incident where a Japanese trader accidentally keyed in the wrong number and promptly lost his employers a lot of money. Languages that incorporate ideas like validation and expected values as first class constructs might be able to help here. The Adriane reminded us how badly humans do when reasoning about systems where multiple agents perform the same task.

great story, but now what do you think apple allow this all stuff?
After a sleepless night, I think I've come up with a multi stage plan to help lose the extra weight, until he's out of the danger weight zone (he doesn't have to be slim, just not obese). Would love some advice:

Conduct several changes to effect his lifestyle and make it healthier

1. Disconnect the TV and get the 3 seat sofa of the the living room. This way he won't fall asleep in front of the TV. This will help him with regular sleep.

2. Not buy unhealthy food. Sign up for a service providing fresh salads each day. Put a salad in his car. For him to always have a healthy alternative that's easier to obtain than other fatting alternatives.

3. Blocks his drive way with wood a metal. Should make him look for parking that atleast 15 mins away from home. 15 mins in each direction is a 30 min daily walk. Force him for some exercise.

4. Fill the house with scales. In every room. Scales that can support his weight. For him not to avoid it.

5. Define together with him his weight target. Find a dietitian willing to come to our house at 9 pm when he finishes working to help him estimate his progress.

6. Getting his brother involved. He appreciates his older brother and enjoys talking to him. Ask for his brother to come over once a week and go walking with him (he lives near by).

7. He also has a very good friend from work (they've been working together for 35 years or more). Not sure how he can effectively help though. Ideas?

8. I Built up a weekly table, each of the family members (we're a few brothers married with or with girlfriends, and I've got a healthy mother). In each hour or two someone else needs to phone him to ask him how's his day / diet going and what he's had to eat today. When he's coming home and when he's going walking.

Any other ideas will be greatly appreciated. Thanks
Using the word "efficiency" anywhere close to the word "market" and not using an economic definition is bogus. You may as well make the rest up too. Those words have a very well defined and useful meaning (theoretically and practically) to most who interact with or study the markets.

> We make safe assets more expensive to lower the risk/reward ratio for commercial activities: we make bank holdings very unrewarding (lower interest rates)

Wouldn't this force people already worried about the future to buy into less abstract stores of value like houses? Wouldn't that just end up monetizing houses eventually leading to a bubble? Isn't the risk/reward ratio an indicator for the health of an economy and isn't skewing it treating the symptom not the cause?

> we devalue the money in circulation and provide liquidity in one move (print money)

But we use this newly created money to buy assets which the market had no interest in buying inflating their price and funding contractors at the expense of everyone else.

> and government invests in big infrastructure (liquidity, jobs, momentum, signalling etc)

But unlike market investors, there's no worry about ROI. Building these large infrastructure projects may pay off but theres no downside and they could just end up making a few people very rich.

> And it works - this is why we abandoned the gold standard.

I thought the gold standard was abandoned because Nixon refused to convert France's dollar holdings back to gold in 1971.

Just another reminder of how systems that you'd think are rock solid often aren't.

In my previous life working with telcos, I once tried to teach a particularly huge customer how to use CVS how to manage configurations across a 10+ machine cluster of machines. They didn't see any value in it, so they stuck to their good old process of SSHing into each machine individually, "cp config.xml config.xml.20131022", and then editing the configs by hand. Didn't take too long until a typo in a chmod command took down the whole thing (= the node couldn't take down a network interface anymore, so failover stopped working), and they spent several weeks flying in people from all over the planet to debug it... and they still didn't learn their lesson!

They also amassed over $3 billion net short positions spread across 75 stocks during those 45 minutes causing significant losses to investors with stop loss positions triggered that would not have happened without Knight's erroneous trades. They didn't just harm themselves...
Yes, but practically, does it matter as long as the autonomous systems continue to provide sufficiently lucrative reasons for real people to sustain its operation, e.g. by continuing to mine or maintain the network under the governments' radar?
In theory I agree with you, but the reality is that even though SQL databases are all on the same "standard" there is enough non-standard things that it in practice becomes impossible for high performance apps.
change the same logic as mining of bitcoin, and transfer it to work:

i mean, mining in this case will be work.. and the amount of work would say how much payment that work diserve..

but how to calculate work in a generic manner without being too linear.. like hours/work.. i mean.. pay for creativity, ideas, less tangible things..

and about other investments. how they would be decided?
this requires a good amount of algorithms..
Knight's systems were sending small, aggressive orders on both sides of the market, so their net positions were relatively small compared to the total volume traded. They were hemmhoraging money very quickly because they were crossing the spread repeatedly.

So either he attached his ID, or he was traced by other means. Stackoverflow can be anonymous. It doesn't require an ID verification. But you can put your real name if you want to, nothing is stopping you.

And again, by your logic you won't be able to give me an example of something that is anonymous: Whatever you say, I will say that the NSA planted a cam in your home. BOOM! Not anonymous anymore.

"The industry points to meta-analyses of controlled isocaloric "fructose for glucose" exchange studies that demonstrate no effect from fructose on weight gain or other morbidities. Perhaps one reason for this is because crystalline fructose is incompletely absorbed."

It may be right that open sourcing the code behind healthcare.gov and crowd sourcing improvements to it could potentially result in desirable outcomes, but it is very unclear whether that is an available option in legal and practical terms. Legally, because support is likely to be governed by the terms of the relevant contracts, and practically, because every pull request will need to be reviewed by a person with expertise who has been engaged for that purpose (which suggests, contrary to the petition, that the problem should be solved by a better and cheaper contractor).

Without that foundation, the petition does not seem to have much utility, notwithstanding its 1000 signatures.
None, as far as I can tell. It was probably just selected because it's a pretty picture.
I love open source, but I don't think Americans need this.

2. I'm sure much of the code is focused on accruing information from various external resources (which puts us back in the blackbox.)

3. I don't need to see the code to believe the site's architecture was poorly implemented.

"OpenSSH for Mac: An amazing ‘VPN’ that requires almost no configuration."

How is running a custom script every time you need connect 'almost no configuration'? It's all relative, I suppose, but having to procure/run a Python script just to make a VPN connection is too much hassle for me.

What Justin ought to do is wrap his script into a menubar item, and submit it to the App Store. That would truly require "almost no configuration" because:

a) downloading/installing the script would be easier, even when using a strange Mac in a cafe or lab environment

b) making a VPN connection would be no less convenient than Apple's VPN menubar item.
Your inclinations seem right. There is a positive correlation between friction (viscosity) and noise, and also between friction and energy waste. It is in part from that connection that reducing noise would boost efficiency.

Credit for using "begging the question" properly, but let me clarify. Propaganda against the Germans was either aimed squarely at Hitler himself or at more abstract representations that didn't emphasize the frankly non-existent physical differences between Germans and Americans. Germans were portrayed with swastikas and Prussian helmets and jackboots; Japanese were portrayed with buck teeth, yellow skin, glasses and slanted eyes.
When you have lets say 4 CPU cores and 1 active thread, Windows [by default config] wouldn't let the other CPU cores go into deep sleep [core parking] by intentionally moving the active thread from core to core. That supposedly improves performance on some tests as bringing a core from deep sleep takes some time noticeable by the tests. Keeping the cores "warm" also means increased power consumption.

Actually, the paper is using a very well known, studied, and used definition of efficiency - weak form efficiency.

This is what current economists use when they talk about markets being efficient, so it makes sense for the paper to use it as well.

There are alternative definitions (strong, semi-strong), both of which have been shown to be mathematically false already (long before economists stopped believing them, sadly)

The one I know of, in the Chicagoland area, is "iSold It on eBay." I believe it is a franchise with a bunch of locations.

They have certain categories of things they will try to sell, and things they won't bother with. If it sells, they can mail you a check. If not, you can pick it up, or they can donate it to charity.

They may accept things to sell by mail, but then of course you're taking a further hit on shipping.

FYI, NYSE rolled back transactions based on predetermined price rules. There were no discretionary rollbacks associated with Knight's "big day".

Don't forget the other market makers; they took the other side of those Knight trades and made the spread every time Knight lost the spread.

What brings the question is 10+ straight quarters of double-digit increases in paid clicks despite only single digit increases in traffic.

That could be

- More ads, in places where organic used to be
- Lower quality organic results

From where I sit, neither of those reflect an engineer's preference. I'd be more interested in hearing an explanation for a runaway ad click growth than hearing a very specific denial.
I for one welcome our new autonomous corporation overlord, which would hire people via TaskRabbit to become its shareholders, and hire lawyers via emails to protect its interests. It would commission new servers on various cloud providers on the fly to avoid being shut down. It would generate revenue by running a SilkRoad that cannot be stopped. It would employ security guards and hitmen to stop people going after it. It would commission black hat hackers to help it infiltrate various intelligence networks, and rely on Mechanical Turk to translate human language into something that makes semantic sense for it to act upon.

Rice was an example that was palatable to both my lazy fingers and I hoped to those who may not have appreciated a jargon filled response. It does not detract from the clearly presented general case which you are more than encouraged to investigate, I have done my part in spelling it out for you.

> but for massive government invervention, such as what you are proposing

I am not proposing anything, I am merely describing. The issue at hand is not readily solved by the markets, which in this situation a) are in a state of risk aversion and b) possess very bad quality information that is difficult to reason about. This is classic market failure that is documented in places better than my mind - go forth and google.

If you are so used to receiving that response that you describe it as "typical" then I would suggest that you are either quite the revolutionary thinker, or that you are, in fact, typically wrong. Which do you think it is?
I've got a little experience with using GAE for a production app, and the datastore was my favorite part. A lot of their components are a little bit jank, but the Python ndb library was pretty nice.

I definitely hope they plan to include ndb in their googledatastore library. I feel like ndb is the actual selling point to me, and would make me really want to use this for a production app.

ESX and ESXi are bare metal hypervisors, unlike KVM which is kind of like a quasi-bare metal hypervisor which happens to sit in the Linux kernel. ESX has been EOL'd, however it relied on something called the "Console OS" to bootstrap itself until the vmkernel would take over and start scheduling tasks. The Console OS was actually a modified Red Hat Advanced Server (later Enterprise Server) instance which once the system was booted would act as a kind of "privileged guest". You could log in to it and do sysadmin-y tasks like add users, install RPMs etc.

ESXi, on the other hand, was written to do away with the Console OS entirely, but it still has a fairly rudimentary shell. Many of the utilities are based on busybox and the idea is it should be stripped down with only really minimal functionality. It also sported something called the Direct Connect UI (DCUI) which is a curses based interface for doing things like settings up an admin password, reviewing logs and changing security settings.
Yes.
Corporations are legal fictions, and have their own set of legal rules. Besides being resolvable, they exist somewhere. They are registered/incorporated/created/etc. There is some jurisdiction. There is usually an agent.

There are all sorts of agency/etc laws that would have to be built to support such a system.

Corporation is literally the wrong word for what this describes.

Yes, if you pay a mortgage and property tax, you should probably itemize. And/or if you have a lot of medical expenses.

Or, if one has a corporation (for freelancing, a SAAS, whatever), maybe the corporation could donate the stuff instead? I'm not sure how charitable donations work for corps, but might be worth exploring.

Yes, it's not fashionable to follow the updated HHS guidelines for healthy eating, but they are rooted in well-tested science. The USDA and HHS invest quite a bit into getting these guidelines right continuing to improve them as science advances. I have not seen a dietary platform as rigorously studied as the one provided by HHS.
No, the banks are scared of investing too.

Edit: sorry, incomplete response. Yes it happens in every currency, the difference is they have mechanisms for handling these issues.
I was JUST thinking about something like this a week ago. I termed it "formula explorer" and was going to ask some people if something like it was in Excel 2013 (at work we're on 2003). This would be great for my mechanical engineering work. We often have formulas that reference many sheets with many constituent formulas. To check them I usually have to create another sheet that shows the flow of values concisely on one sheet, basically a manual version of what Slate does. This tool would automate that, looks fantastic.

This is incredibly interesting. Corporations essentially crowdsourced the way bitcoin is. I disagree that these applications will reside in the cloud however, because those are essentially provided and administrated by a central entity.

It's more likely that such an autonomous corporation would provide a cloud service. The protocol could be designed like bitcoin to reject hosts that don't meet certain criteria (such as latency or security). With Homomorphic encryption techniques being advanced these types of clouds could even be somewhat secure.
Pretty cool! Does it do Stack Overflow Careers? And is it open source?
Actually you have my support for going manual. I still prefer to do all my projects without ARC (and I'm not old-school, unless 2009 is old-school). I just feel dirty everytime I use ARC, like I'm being sloppy haha. It also hides a lot about memory management that new people might never learn (and thus be in bigger trouble when something does go wrong). But I accept that it does have major advantages...

One trouble now is you never know if a library or whatnot will be ARC so it fragments things somewhat.
I wonder what the relationship is between the seemingly negative results you cite from praising hard work and the popular claim lately (and one backed by some studies, e.g. http://www.sciencedaily.com/releases/2013/02/130212075109.ht...) that children who are praised for effort rather than skill are , in fact, more likely to be successful.
They have recommended a carbohydrate rich diet for years and it has gotten us what? Appeal to government authority is not compelling when it comes to dietary advice, especially when you consider the power of the food lobby and the well understood impact of lobbyists in American politics.
Careful not to spoil your relationship with him over it. Try to have some serious conversations with him about it. Unless he is bought into your plan, it might be impossible to do anything about. People have a hard enough time losing weight when they are actively trying to.
It wouldn't be our only non-ARC framework. It might be interesting to benchmark an ARC version though.
