Great, let me answer your questions one by one:

HyperDex is a next generation NoSQL store, so it kind of resembles traditional NoSQL stores like Mongo, Cassandra, Riak, and Dynamo, with a rich interface similar to that of Redis, but it offers much stronger properties than all of these systems. It differs from Mongo in that it provides much stronger consistency and fault-tolerance guarantees. Mongo's default will gladly pretend that an operation was committed even before it was seen by any server. HyperDex differs from Redis in that it shards its data across a network and is generally designed from the ground up for a networked environment. Both Redis and Mongo can and will return stale results following a failure whereas HyperDex will always return consistent results -- it guarantees something called "linearizability" for key-based operations, which roughly means that time will never go backwards from the point of view of any client. And in spite of offering stronger properties, HyperDex is faster than both Mongo and Redis on industry-standard benchmarks.

The HyperDex coordinator sounds like a singular entity, but is in fact a redundant, replicated service. The Paxos algorithm (provided by the ConCoord implementation here: http://openreplica.org) ensures that the coordinator overall can survive failures of some of the coordinator replicas.

Building a pub/sub system on top of HyperDex would be an excellent project.

HyperDex does not support "capped collections" out of the box, but it would be trivial to implement these with a background thread that prunes the database. The data store supports sorted queries, so you can say "return the top-1000 objects sorted by insertion time" or whatever else metric you liked to sort by. And you can delete groups of objects. These operations are implemented efficiently.

Hope these help.
haha they do look similar.

I try to ignore this stuff. It doesn't really matter if he committed suicide or not, and the folk mythology is just silly.

If you want to learn more about Turing and the Entscheidungsproblem I recommend Charles Petzold's "The Annotated Turing". It has some great supplemental explanations to go along with Turing's paper plus interesting historical details. Petzold strikes a good balance between presenting the actual work and talking about Turing's personal life.
I'm a landlord and I would love this. Here's what I need it to do:

1. List property on MLS.

2. Be able to run credit checks.

3. Is there anything it can do to make checking references easier?
It's interesting how this has played out exactly the way Clayton M Christensen predicted in his Innovator's Dilemma book years ago. Back then, flash was barely on the radar of most consumers, and yet, Christensen identified flash as a primary candidate to make traditional harddrives obsolete the same way desktop harddrives had made mainframe harddrives and minicomputer harddrives obsolete. Chalk one up for the guy, his Innovator's Dilemma model is really well thought out.
You win the award for the best comment on HN ever.
As reitzensteinm pointed out, I'm not expressing my own opinion either way.

I'm simply pointing out that, under the current extradition treaty between the UK and US, O'Dwyer doesn't have a leg to stand on. Those in disagreement with the course of proceedings need to work to change the system (e.g. removing the offence of facilitating copyright infringement, if you disagree with the principle of people being prosecuted for simply linking to infringing material) rather than seeking an exception for a particular case.

I think the point you were trying to elicit with your Pakistan example is that US citizens should not be extradited to Pakistan to face charges there for things that do not constitute criminal offences in the US. This is taken care of by the 'double criminality' clauses that most countries include in their extradition treaties.

O'Dwyer is in the somewhat unique position that, although it has been ruled that the allegations against him, if true, constitute criminal offences in both the UK and US, the former has shown no interest in prosecuting, but the latter has, so he is facing extradition...

Eh, I think some of these are circumstantial. The dating one probably applies to a very specific type of person. This is the one that does it for me:

Why are even some affluent parts of the world running out of fresh water? Because if they weren’t, they’d keep watering their lawns until they were.

It's all about greed/constraints/pressures/incentives/desires. People want to use water, but people don't have an incentive to keep water use down. Instead, they put pressure on engineers to bring availability up. And when availability, or supply, goes up, demand comes back in to seal the gap.

A deeper look at the Clipboard bookmarklet (Fluent 2012 Keynote)
Nothing, in fact that is encouraged. I could imagine having a “checking account” in demurrage currency that my paycheck is deposited into, but at the end of the week or month I sweep excess funds (my savings) into a “savings account” backed by treasury bonds, gold, bitcoin, or similar.

The point is to keep cash itself in circulation, regardless of economic circumstances. Had we a demurrage currency in 2008, we might not have had as severe a “credit crunch” as we did--people would still want to loan or invest even in bad times. Demurrage removes, through negative incentive, the “sinks” where money can end up in unproductive storage on the ledger of some company or individual somewhere, and instead keeps it flowing through the economy.
Why the entire planet is not available: I wanted to host it on an inexpensive server (only what's needed), generate maps only for regions that are popular among my target segment (popular tourist destinations mostly) since compute was also an issue - I generated all the maps on a VM on my desktop.
I download the openstreetmap data to my local hard disk for the regions I need, generate the maps using mapnik and extract poi data using python utilities that I wrote. Not a whole lot of tweaking but I did have to write my own tools.
Whilst they were quick tro deny offshoring was the issues the real crux is that this is old application software they are running and this has not happened in the past.

They also had a large UK array for IT staff, they do not now as they outsourced them.

From many many sources of ex and non-IT staff at the aforementioned bank have all said this type of failure should not of gone on for as long as it has and there is no explanation beyond incompetant IT staff being at fault.

Draw your own conclusion but it's like this. Just becasue your building has not caught fire is no reason to replace reliable/known to work fire extinguisher with a cheaper model that looks the part.

Dont get me wrong, I'm sure IT staff in outsourced countries are great, but you just can't buy in years of experience and local knownledge of how the IT infrastructure evolved and why and what its nuiances are.

Moral being - when you have a bunch of staff who mess up there job and casue the company to lose money - REPLACE THEM and not the IT staff who have been doing there job just fine.

Also when your offering out volintary redundancies please remember that it is the competant staff who know what they are doing and can easily get another job that will take you up on the option rather than work in a job that is being pissed upon by others mistakes.

It is what is not being made public about this whole mess that is more worrying, but lets see what happens and what is admitted too.
This is Keynes argument against Demurrage Currency, the fees can be evaded by using a competing currency. When demurrage has been used successfully in the past, the main competing currency has been broken (30's Austria, depression era USA)

As I see it you have 2 possibilities:

1. Find yourself work by handing cards ... just like you do now. I think it will eventually work after you land a few projects.

2. Use an aggregate freelancing site like oDesk, vWorker etc.
Here is a link to an interesting story about freelancing on vWorker:

Love the idea, but my first thought was "man, I have to rate everything I've watched/read/played AGAIN???" I really wish there was better interchange/exchange of this sort of data, because it's sad that my first impression of your app is so quickly soured by that.
This is the logical move for padmapper. I wonder if the press they've been getting will be enough to seed their user base to make it self-sustaining.

It would be ironic if Craigslist just helped create a viable competitor, though this is unlikely.

I was not going to was not going to post my advice until I saw how many people here were saying the opposite. Do not, under any circumstances, work for free.[1][2]

When clients agree to work with you, they risk more than money. They risk their time, their peace of mind, their ability to be proactive in a changing environment. The best clients are the ones who realize that. As such, they will be uncomfortable with the thought of your working for free, since the unsustainable nature of your position endangers their peace of mind. They're happy to throw money at you to protect what really matters to them.

In terms of practical advice, if you don't yet have a network, I recommend checking out oDesk, Elance, and other sites. Don't try to underbid providers working from developed countries, and don't spam every buyer with proposals. Just write personalized, specific letters containing some of the details you would be thinking about as you went about solving their problem. Before you know it, you will have more work than you can handle.

[1] I don't consider wedding videos, etc. made as a gift to fall under the category of freelance work. If this is what you do for a living, it's fine to gift your services, but trying to leverage free work into a sustainable career is an awful idea.

[2] The exception is support. Phone calls are free. Bids/proposals are free. Your work, the value you provide, is decidedly not.
I am in a similar situation, but attacked it from a different direction. We are almost ramen profitable, and built our company (http://codiqa.com/) almost exclusively while working 9-5 jobs. We'd work 9-5 then come home and work four hours a night, sometimes more. We did that for several months before we launched in February of this year. I don't sacrifice personal time, and we are still growing. Granted, we are young and have very few obligations, but it works. We have never taken on client work, but it's definitely an option should we need to.

The point is, I don't agree you have to sacrifice personal time to be successful. I think it's very healthy to have things outside of work, if only because it makes you do the work that's most important when you are working.

That being said, I probably work way more than I realize, because it's not really work to me.
We've been doing this in the UK for about a year now (http://rentify.com).

Landlords are really receptive to it. We're currently processing about 4,000 tenants per month & acquiring landlords pretty quickly too. You shouldn't have any problems convincing them that this is an improvement on the alternatives :)

Credit checks are what sparked our interest. I was charged £450 for a credit check through a letting agent. I asked why it was so expensive and he instantly dropped the price to £150. (They're nowhere near that much wholesale.)

Good to see other people fixing a broken area.
On paper, it sounds like a great idea, but the issues of adoption (why would anyone use this?) and liquidity (why would you keep a balance of freicoins any larger than you had to?) really defeat it before it even gets out the door.

This is something that needs to come from the top - governments need to stop taxing liquidity (sales and income taxes) and start taxing net worth.

I think a map of the entire world is too big to fit on an iPhone (at least in pre-rendered map tiles - not sure if 64G can hold vector data either).
An option for you could be to download the maps of all towns in your path and rely on paper maps for highways connecting the cities. If you do end up using my app and don't find a map you need, just let me know :)
> A questionable assertion

It's not my assertion, but that of District Judge Quentin Purdy:

> The judge agreed with John Jones, barrister for the United States government, that “because he was intimately involved in deciding who was allowed to post links on the TVShack websites, which links would be posted”, Mr O’Dwyer’s alleged conduct was a criminal offence under British copyright law.

> In its argument the defence had cited the 2010 case of TV-Links, a website that offered a similar directory of links to pirated material to TVShack. The judge found it was acting as a “mere conduit” and dismissed the criminal charges against the two men who operated TV-Links.

> Judge Purdy however found Mr O’Dwyer had exercised too much control over TVShack to successfully claim the same defence.

Thank you!
Personally, I think Moose' value to the community is much larger than that it just provides good OO.

It pushed a much more declarative approach than usual, that swaps over to other projects (Moo, Mo, even Class::Accessor supports has declarations now). It has a community that is focused on best practices with regards to OO. It put introspection more in the spotlight (like the idea of getting Getopt definitions by introspecting classes).

It is also flexible, which allows for lots of extensions to its functionality. That means a lot of concepts are tried out on CPAN already. Even if someone doesn't use Moose, there is lots of OO knowledge to be found in the ecosystem. Same goes for runtime type constraints/coercions.

Then there's the p5-mop project, that would provide a common core, so many of the things above could find themselves in a much more light-weight and broadly usable variety, with side-effects like less heavy anonymous packages.

Personally, while I'm very excited about where Perl 5 has come so far, I'm even more excited by the things we haven't thought of yet.
We'll have to wait and see about the "dust immunity". "Centrifugal force" is not by itself enough to prevent dust buildup, or existing fans running at higher RPMs would be spotless.

As for quiet, you'll still have to pair this with a case fan if you want any exhaust, so I'm not sure it compares with a fanless solution for overall noise level.
Economically, this is utterly backwards. To those without access to the cheat-code of newly created money, USD basically is a demurrage currency through inflation. In any environment where currency loses value, those with the most assets (your "1%") can best manage their investing to avoid losing value, while the people with modest amounts of savings get screwed either directly by inflation or through encouraged patronizing of the fraudulent consumer-financial industry. "Hoarding" assets by the middle class is what gives people the freedom to turn down specific jobs and hence puts them in a much better bargaining position for favorable working terms. If you want to even the wealth distribution, you have to empower the middle and lower classes to become financially self-sufficient, not simply try to attack the upper class.
ASK PG: Can we get clarification on the title changes?
If this is a script that the mods are trying out, or even a policy change, that's fine. We, as a community, can give input to help refine it and make your guys job easier. Right now there is just a lot of confusion, that can be avoided. I know you don't like these sort of meta threads, but without clarification, every front page story with a changed title becomes one. Asking/answering this privately doesn't scale very well, because of how many people will still be left in the dark.
Ask HN: Please give us your valid feedback to improve Skillendar.
Skillendar is back! Now with more focus on you and your neighbourhood. Please have a look and give us your valid feedback on design, usability, features etc.

A bit about Skillendar:
Skillendar is a neighbourhood network for you to connect with and reach out to your local community. Like Facebook is a network for friends and LinkedIn is a network for professionals, Skillendar is for your neighbourhood. Also Skillendar has a unique calendar based skills search that helps you find the availability of people in your neighbourhood who are open to share their time or provide a service, at a glance. Hence the name Skillendar, short for 'Skills On Calendar'.
Yeah that's a good point. We're gonna work on that, for now we just wanted to test the group recommendations...
I don't see the point of using demurrage currency when I can just use bitcoin for everything(store of value, exchange, etc).

I am happy to be proven wrong, though.
This doesn't make any sense, many members of the #occupy movement already use Bitcoin because the cops often try to hold the money for "evidence in an investigation".

I agree it really depends on where you are. Craigslist was slow to expand past the major Canadian cities, so in the smaller cities UsedEverywhere or Kijiji were first and remain more popular.
David Wheeler (theory) started working on a stored procedure centric project a while back and as a result extracted the DBIx::Class connection logic into DBIx::Connector - which I have a feeling you're already using.

I spent a fair amount of time hanging out in #ledgersmb a while back and in spite of being the project founder of DBIx::Class, I don't think I ever felt I had a convincing argument for using it, so honestly I'm glad you're not doing so (if I ever come up with an O<sproc>M or something I'm sure you'll find out :)

What I find weird is that there is no mention of Khan Academy hiring any educators. Even if your teaching methods are non-traditional, you still probably need someone with traditional teaching experience to tell you whether the lessons will actually be effective.
Or you could simply begin to learn everything there is to learn about that niche. I think the point Patrick is making is that knowing your own specialization is as, if not more, important than your customer knowing it.

If you're "a programmer" then your customer base is pretty much anyone who needs software. That doesn't help much because you're back to the same question: "who needs software?"

If you're an expert on sites for heritage Asian language schools then it's much easier to find schools->Asian language schools->heritage Asian language schools. Odd though it may seem, it's easier to market to a small, well defined niche than a large amorphous blob of "potential customers."

Kijiji was the would-be Craigslist killer that eBay built internally after acquiring a minority share of Craigslist itself, and then finding out that Jim and Craig were not interested in the full merger that eBay had expected would follow in due course. (From which much legal wackiness ensued, as Craigslist tried to limit eBay's access to their internal data once it became clear that they would be competing. This is probably still ongoing.)

Looks like they've dropped the separate branding, at least in the US.

To corroborate #2: One of the things often said about depression and suicide is that severely depressed people are too depressed to have the energy to commit suicide. It's only when they start coming out of the pit and feel a little better that they'll get the nerves. That's why depressed people are (or at least should be) monitored like crazy when you start giving them antidepressants. It's a cruel irony, but making a depressed person feel better can actually make them more dangerous to themselves. Unfortunately, people see their friends and family starting to claw their way out from the pit of despair, so of course they seem "so happy" (comparatively).
Why are our personal reproductive choices so rarely informed by these Malthusian dynamics, let alone by the enormous personal burden involved in raising children? Because a nation/ethnicity/clan/family whose culture is comfortable with honest consideration of such questions does not grow as fast as one in which reproduction is seen as a crucial to identity and survival (both that of the group and that of the individual), and in which critical consideration of reproductive behaviors is rejected as perverse, judgmental or selfish.
