I'm not sure that I understand the big picture here. Is my summary correct?

This optimization does not apply to Postgres in general, but only to citrus_fdw and other column-store foreign data wrappers.

The Postgres execution engine was designed to operate on a row-store. Even so, it can operate on a column-store via a foreign data wrapper like citrus_fdw. However, to do so it must currently reconstruct rows-at-a-time to fit its row-oriented nature. As a result, it cannot currently realize the potential performance benefits of using a column-store for certain queries.

This article is about an extension that adds some new column-at-a-time aggregate functions, then hooks into the Postgres executor to modify eligible query plans to use them. It thus enables Postgres to take advantage of the column-oriented nature of the citrus_fdw.

Is that an accurate way to look at it?
I'm just really curious about how it'll turn out.
Are there still problems with apps that require the initialization system. I never was able to get things like dbus working in Docker.
looks like they are using svg-edit.
France doesn't have a full separation of powers since the president's executive needs the OK from the legislative power.

The Montesquieu proposal is the best mechanism that we have to avoid institutional corruption. If the power is held only by one group (legislators) corruption is inevitable.

If you only care about the output then Plato was right and the best system would be an aristocracy that cares and chooses the best for the country.

Interesting, any links which expand on the issues?
Notification about not being to save someone else's scene keeps popping up after I hit Dismiss. I know I can't save but annoying nonetheless. Otherwise feels quite polished and impressive overall.
I have two things to say.

1. I agree with what minimaxir said. It seems like friends of friends of friends control the entire place. HN seems less "controlled" than PH. Even Ryan himself went above and beyond to make sure that Alexis' friends were able to comment right off the bat. (https://twitter.com/rrhoover/status/489931085048860672) In hindsight, this paid off since he got funding and I don't blame him. But to the average user who has been waiting to comment - it's incredibly frustrating.

And why the heck is commenting disabled by default anyway? Why does it sound like a good idea to only allow friends of friends a voice to comment? Provide some type of "participant threshold", and then allow everyone to comment and block those who abuse it.

2. They got 6.1M in funding. I am not from the startup "funding" ilk, but that sounds like a ridiculously high number to me. What could they possibly be building that requires that much capital? The site and premise of it now is fairly simple to implement and code. Perhaps they have grand plans that are way above my head?
Yes, but how many of your ex-girlfriends or ex-boyfriends run around trashing you in public? I'm guessing not many.
Not according to the article. Belkin claims that it was a problem with the server they used to allow the router to check for internet connectivity.

If it comes out that Belkin is actually routing their users through their own DNS, I would hope it would be a huge privacy scandal.

There is no reason for them to run a DNS infrastructure for their clients, and doing so provides them no direct benefit, has no clear applications for building routers at all, costs money to maintain, and is a huge point of failure.

I can't imagine them doing such a thing for a few advertising dollars.. the only reason a router company would do that is if they were paid by the government or something. This way Belkin could reroute your internet traffic through whoever's servers whenever they wanted, and you would likely never know.

Anyway, that sounds a bit far-fetched, so I'm going to hope that Belkin is telling the truth.
Is mere survival enough? Or do you mean if I maintain my current standard of living?
Daily Stories of How Companies Got Started, Inspiration for Entrepreneurs
check out http://www.makingof.co

#Problem

When we think about Google, Facebook or Apple, we tend to forget their humble beginnings. When we read about startups, we see big IPO’s, Million $$ fundings, huge exits… Yet these stories are of little benefit for aspiring, or struggling entrepreneurs. There are no real lessons in those stories, for the entrepreneur just starting out or thinking of building a startup.

#Solution

I started MakingOf.Co to collect the inspiring stories of how some of these companies actually got started. Their modest beginnings are full of clues, lessons and inspiration. MakingOf.Co aims to inspire more people to dare to work on their dreams.
I find the promotional video incredibly well made. Anyone know who made it?
They are because the ISP is supposed to provide DNS. That's what you're paying the ISP for. If the ISP paid belkin to run the DNS servers then yeah, that's no big thing, just a service outage.

Lol, 6.1M for a HN-alternative for products (and the HN original has been created by one guy solely).

That's pretty sick :s
Was expecting people to talk about apps centered around delivering healthcare advice/information cheaper/more readily to people, turns out we're just going to keep finding ways to use tech to market ads to people.
To me Product Hunt complements HN in a really fantastic way - it's made HN a much smaller target for every startup that wishes success was as simple as hitting HN's front page once or twice a week with some contrived content. Those guys have a better outlet, and we have better content.
What may be overlooked is that continuations are a useful way of storing state when using a stateless protocol such as HTTP or when dealing with asynchronous communications in general.

They are useful because they are lightweight. There's no serialization/deserialization, no read/write from persistent storage, no additional tiers, no additional layers. It's a simple mechanism that's provided directly by the programming language in which the application is written.

Out of curiosity, what problem do you experience due to the 30 item constant?
Bill from WePay here - thanks for asking.

The value proposition of WePay Clear isn't entirely captured in TechCrunch's choice of a headline, though they certainly have sensationalized it by drawing a Stripe comparison.

Yes, WePay Clear takes on fraud responsibility & shields the platform. (as does Stripe Connect)

However, WePay Clear does this in a whitelabel fashion, so that sellers on platforms do not need to create a WePay account.

In other words, it's not just fraud protection or whitelabel - it's whitelabel payments AND fraud protection.

Our launch partner in this is Freshbooks. Freshbooks currently offers several payment gateways/merchant accounts as an option to sellers like Authorize.net and Stripe. But their new primary "Freshbooks Payments" offering is built on WePay Clear. You can check out the experience here: http://www.freshbooks.com/blog/2014/10/01/introducing-paymen...

It's super obvious that it would be CGI after reading those specs. They're pretty impossible with current technologies.
Absolutely... I get that, but its only functional for non-optimised code.
My point is that for anything non-trivial, its not going to be terribly useful. You're still gonna need to understand what really is going on, optimisers mangle the code out of all recognisability for this decompiler.
I currently could only hold for 3 months but that's because I invested all of my savings in a company that crashed. I'm slowly rebuilding my savings now...

A word of advice for anyone who wants to start a company, do not go into debt doing it. You'll regret it.
Fair point, and thanks for the kind words!
Cool, but it's odd that the sail rotates around its own center point. Probably would be more realistic to have it rotate around a mast at the leading edge.

I'd also love to see centerboard or keel forces since that's what makes the boat go forward.
I totally disagree. The government does not, and should not, break the law that citizens are held to all the time. If a government agency has the ability to perform an action that is otherwise illegal for a person who is not a member of said agency it is outlined in the law. If it is not outlined in the law then they are in fact committing a crime and may be criminally liable for it.

That is why whenever there is a police-involved shooting there is supposed to be a review of the incident to see if the officer in question followed the guidelines as outlined in the law. If it is determined that the officer did not follow policy then he can be subject to criminal prosecution.

I'm not making this up, it happened recently. In South Carolina a state trooper shoots an unarmed man for reaching into his vehicle after being asked to show ID. The dashcam clearly shows the shooting was entirely unjustified. That trooper was fired and charged with assault and battery, facing a potential 20 years in prison. That is what should happen when a government agent breaks the law.

So, unless the agent from the original article had permission under the law to falsely pose as a real person without that person's permission then they likely broke the law and may face criminal and/or civil action.
I think what you're failing to understand is that, when the government does something that is legal for them to do but illegal for a citizen to do, by definition it isn't breaking the law, because the law allows for it. The problem is when the law says the government can't do it, but they do it anyway. That's when the government is breaking the law, and there's nothing right or good about it. They should be held accountable for such illegal acts.
Yes. If the eInk screen uses the card plastic in place of the glass which usually backs such a screen, it can easily be thin enough for a credit card form factor.

Touch screen digitizing can be done resistively with overlaid wires over the screen. Their touch interface doesn't have to be super accurate, you only seem to touch in a few distinct locations.

A microcontroller is already inside every chip and pin card on the planet. They usually run Java. Yes, Java :)

Bluetooth is just more silicon to do the radio, not hard to stick it on the side of the microcontroller silicon or even have a two-die configuration with wire bonding between the dies. Go look at TI or Freescale 2.4 GHz radio+micro parts, same thing just there it's in a QFN or other solder-down package, but the dies themselves are quite small. A 2.4 GHz antenna is easy to fab out of printed silver or other printable conductive material onto plastic.

NFC is already in many credit cards for the whole "tap to pay" thing. It's just some extra silicon on the side of the microcontroller in existing solutions. Harvesting power from NFC is just some diodes and a resonant circuit along with loop antenna.

Realistically, such a piece of silicon plus the antennas plus the plastic card should only cost you single digit dollars in volume to manufacture. Adding an eInk screen like that is another couple bucks, at most. The $155 price point is probably so they can make back their up-front costs as getting customized silicon isn't cheap, nor is some of the development work they did to get all the features integrated.

If this concept takes off, I'd expect in 2-3 years that cards like this are issued by banks for free to customers. The cost of manufacturing really isn't that high.

EDIT: But getting enough battery packed in to avoid charging every day or two, that's really the novel part if they have real bluetooth operation.
Same here. But the history still says I added a point.

Good suggestions. Most of these have published papers, we'll add that to the documentation soon. In the meantime you can read an overview of the Watson Jeopardy system here: http://www.aaai.org/Magazine/Watson/watson.php.
Interesting to keep in mind whenever a link that makes front page of HN drives 20-30k clicks to some "scalable" web app spread across a couple racks of machines which is then annihilated under the "load".

The original and the most powerful disassembler is IDA Pro. The project was started in the 90s and has been used for security analysis, antivirus work, protection analysis/research, hacks as well as normal dev work in the closed-source ecosystems.

https://www.hex-rays.com/products/ida/index.shtml

The author has implemented a decompiler plugin over the top of IDA and it works on the real-world code. The point here is to annotate the disassembly bottom-up and then decompile.

I don't want to bash the author of Snowman - this kind of research is serious fun. Yet, IDA has an insane lead.

I'm by no means an expert, I'm just a linguist that's been learning python and NLTK for a little while. I would assume the demos don't show the potential of the technology. This kind of tech shines when you customize it and train it with domain-specific data, am I wrong?
I guess the OP means the time it would take to run out of cash while keeping reasonable monthly expenses ("reasonable" would be slightly lower than they are now for you).
Incidentally, most companies that "launch" on PH end up just submitting their product to Hacker News the same day, so there's really not much difference. (the new "show" tab may put a better emphasis on such posts)

For this poll, I'm assuming it means liquid savings, although you could use a reverse mortgage to live off the equity if you had a plan for when the equity was exhausted (use the last of the proceeds to live on a boat 30-40ft in size off a mooring ball somewhere warm, which costs next to nothing).
Just guessing - internet explorer under wine.
But would you be able to find/remember all those cards if they were stored in this thing? Isn't it the pretty plastic and embossed pictures that scream "Barnes & Noble"? Would burying that inside a Plastc mean you never used them?
The point is in the amount of users (~400M) that use it and the developers that make it. Yahoo's webmail isn't really a rocket science and any decent developer could make it work at least. The point is in the company that doesn't care.
Fun stuff. Could you add a numeric value for the green line? That way we could see which setting get the best forward motion.

Actually, I was thinking of INRIA and CNRS in France. You don't even need to speak French to apply. Basically, there are two types of positions, junior and senior. What I find surprising is that many junior researchers apply for a professor position it they think they won't be able to get a senior researcher position (there is less and less of those). They trade a lot of academic freedom for about fifty percent salary increase.
If "passed inspection" implies "is legal", Airbnb would be taking on substantial legal risk and it would remove probably 99% of the listings in NYC (I only mention NYC because I live there and am aware of the laws), making one of the most densely populated areas a big hole in the map.
the third highest voted product on the page right now is a $125 monitor stand....
Fraud protection is an odd marketing angle.

The merchant bank is the one that gets hosed due to fraud, so anti fraud technology helps Stripe, Paypal, WePay, etc. WePay is marketing that they are very good at not screwing themselves.

There are clients that care about anti-fraud, such as ecommerce companies that ship high value electronics, but WePay has no experience in this category.

The crowd funding space has fraud issues as it is a method for turning stolen cards into cash, but reversing a pledge is a lot easier than un-shipping an xbox.
I'm going to recommend you head over to https://www.reddit.com/r/personalfinance and https://www.reddit.com/r/financialindependence.

Emergency savings to live on should be 6 months to 1 year, depending on how easy it is for you to find work, and for retirement/voluntary reduction in hours worked, you'll want to plan on having saved up enough that you can draw 4% of the retirement savings every year; at that burn rate that should last until death.

Don't discount social security if you're entitled to it. You may not receive full benefits, but you will receive something. I suggest http://www.ssa.gov, calculating your benefit, and then reducing it by 25%. That takes into account the chance that Congress won't top of the SS trust fund with general tax revenue when the trust fund is exhausted.
more than 3 months, less than a year. It would depend on how much warning I had and what time of the year it was. If I was given warning before May I could plant a larger garden than normal and get more livestock so that food would not be an issue. I have enough savings and liquid investments that I could cover other costs comfortably for 9 months.

If my income dried up tomorrow then probably only 3-6 months.

Of course there's always a lot of contingencies in questions like this. In my case I could fall back on trade skills pretty quickly as they are always in demand in my area and thus would have an income of sort though probably less than half of what I make as a developer.
I don't see the point of having a set of accessors on a Ball object from the point of view of a Dog object. It is really up to the programmer to have method names that makes sense in the first place. I don't see how a dog.Weight() makes more sense than the convention dog.GetWeight().

Never the less, I am now intrigued by the book mentioned. :)

[edit] I am curious about the book.
Savings is useless. The idea is to try and outlive your savings. It's a race to dying before you're broke. Real estate investment is the key -- passive income steams, then you don't ever have to worry about money again.
Nobody's arguing whether the system is broken or not. Or whether it's fraud or not. You're attacking a straw man.

The truth is most salaried workers aren't billed per hour.
At my current standard of living: 2-3 years but if I moved somewhere cheap sold my car and doubled down on beans and rice: 5.

Side note:current liquid savings: 16000.

Except it will forever be called that.

Not as long as you replace it with a new name. Your "new" problem doesn't sound like a problem of stickiness, it's a problem of never giving it an actual name in the first place, or when it was rolled out.

Look at the Orbis and Durango for names widely used in when the press was rumor-mongering that went away as soon as the devices were revealed. We've even changed our internal code names on projects without much fanfare, as long as the name change represents a milestone in the project or a difference in audience it's easy to cut over.
This is a repost from July.
And that seems to be the eternal issue. Poettering seems to come at this not from an admin perspective but from a developer perspective. And with RH shifting their focus more and more towards cloud computing, so is systemd.

And in cloud computing the admins are not kings, but peons.

Peons tilling the cattle (server) farm of 100s of servers, each running any number of VM instances. If one or more of those instances go down, new ones are spun back up.

And you see this attitude within systemd. If a daemons crashes you don't leave it down and try to figure out why it crashes. Instead systemd will simply restart any daemon it finds not to be running when it should.

Basically this is not uptime by way of applying carefully measured and maintained administration. This is uptime by machinegun.

It is what allows anyone with some grasp of php to rent server time on a amorphous blob like the Amazon EC2 and spin up the next Twitter or Facebook.

No need to optimize for or maintain the hardware. If the current load is too much, wave your credit card and have 1000 fresh instances behind the the load balancer, courtesy of Amazon or RH.

I already do this. Amazon knows my credit card info, so do many other merchants. If I'm doing any kind of mobile payments thing then my phone has access to my bank somehow, too.

My concept is basically just "mobile payments" but enabling it for locations where merchants don't have the infrastructure yet. The added benefit is every transaction has a different card number, so merchants who store card numbers and get hacked provides no benefits to the thieves. Granted, any of the mobile payments things should be doing this kind of security thru obscurity, but I have no idea if they are.

This is not novel.
