Seller(s) of stock are not required to place shares on different exchanges. This is a side effect of the process of trading, as the NBBO price bounces around to different venues.

If I offer 100,000 AAPL at NBO at exchange X, and you are willing to purchase 100,000 AAPL at NBO, your buy order matches mine exactly and the transaction takes place. This is highly unlikely, of course, that an enormous stock transaction like this ($50M) will take place this way.
BTW, I suppose Postgres is a perfectly adequate replacement?

If you're starting from zero, don't have any too obscure or extreme requirements and don't have to integrate with third party tools that don't support Postgres, then absolutely.

However if you already have a large Oracle based codebase and/or have to talk to third party apps that don't support Postgres then your migration costs can quickly swamp your license costs.
I understand that it probably isn't relevant, but I don't think it is sexist. It doesn't say that an almost entirely male team is good nor bad for the project.

My 6 year old and I often boot up the old 8-bit machine that I have reserved in a corner of my lab just for this purpose. I have to say - there is no better way to teach a 6-year old to code than to fire up a BASIC-running 8-bit machine from the 80's and let 'em at it. Something so satisfying about hearing him read out his code .. "10 ... do this .. 20 .. do that .." ;)

As an aside, does anyone make a cron panel for humans? I'd find that really useful as I'm usually so busy being distracted by the next big thing that I forget to take care of repetitive tasks.

I know I can achieve something like that with my Google Calendar but I don't like the way repeating events fill it up -- it would be better if they just showed for the next occurrence.

One of the developers here. Glad you liked the branding! As you've mentioned, our goal is to stay stupidly simple to use. We want users to forget we're even here, until something isn't working. Now as for your questions:

> - how do you prevent unauthorized snitches from screwing with your data?

We don't currently have such protections in place basically because it hasn't been necessary. We keep an eye on things and if we start to see such traffic we'll investigate what should be done at that time.

> - why only an iOS app? This excludes lots of potential customers (including me).

Time and customer requests. We've started looking into building an Android app and glanced at Windows Phone as well. That said, mobile apps aren't required to use DMS, the default is to send emails.

> - why not offer an API, so we can securely fetch the status of our snitches?

We have actually just started rolling out a new API! If you're interested in helping us beta test this, get a hold of us at hi@deadmanssnitch.com.

As for pricing, plans are built around the peace-of-mind our product offers customers. Our canonical example is an ops engineer needing a backup only to find out that backups haven't worked for the past weeks/months/etc. At that point the cost of DMS is a pittance to what the lack of backups just cost the company in question.
Thanks for sharing the youtube link. This is the most (only?) interesting interview of PG I ever watched. It feels way more closer to the PG who wrote the Lisp- and hackers-related essays (or those in Hackers and Painters) than the PG who is responsible for YC Startups. As you say, it's funny how it is the same person :).
I think it's the "slick floor" feeling that causes the heavy/bulky feel; it's as if your character has a ton of momentum (due to a ton of mass, presumably, though you do move faster in Quake).
I'm a huge fan of CouchDB, but I think that CouchDB is the answer to his problem just as much as using some other database like Postgres is the problem to begin with. The problem with "REST" (oh yeah, baby, I'm getting the air quotes out) APIs to begin with is most of the time we heavily couple them to the fact that they will be consumed by a browser client. Design your REST APIs to stand by themselves and design them to be consumed by any client. There is no doubt that web browsers have special needs, address those special needs with a (hopefully) thin layer between your REST API and the browser.

Good point, we'll make a note to include this in our documentation!
I see this idea very promising. This problem is a very good research topic for academics. I'm sure the current shortcomings can be fixed.

The main problem is that all the transactions should be public, but the individual votes should be kept as private. We may overcome this problem by a 2 level system, just like in the traditional offline elections.

1. Ballot box level. Each 'digital ballot box' has a certain amount of voting coins. Voters go to a voting site, prove their identities and are given a key for a single transaction. This transaction transfers one voting coin from the ballot box to one of the recipient wallets (each wallet representing a candidate or a decision).

2. Network level. All transactions from ballot boxes to candidate accounts are public and verifiable using bitcoin protocol.

At the end of the voting period all the remaining unused coins must be transferred to a common wallet representing empty votes. So these numbers must mach: Number of coins = number of voters = sum of coins in all wallets

Candidate with the most coins wins.

The main benefit of bitcoin voting is that it's not a centralized system. It's open, online and verifiable.
So instead of:

> Ballast is invoked as part of the SSH login process, hence has access to the user name, which is not available in traditional load balancers

You'd write:

> Ballast is invoked as part of the SSH login process hence has access to the user name which is not available in traditional load balancers

I'm afraid i can't agree. Both of those commas seem grammatically necessary to me.
I think mavdi really meant "diagnosed sooner". Or perhaps cancer deaths could be prevented? Either way, just google "cancer blood in urine" or stool and you get the idea.

MSE is actually really cool and makes streaming media over HTTP much more pleasant. I'm not surprised they want to keep the number of codepaths they have to support low. As the GP mentioned, MSE is coming to Firefox soon anyway.
Actually something like:

0 6 * * * /bin/sh my_cron_job.sh && curl https://nosnch.in/abc123

Then, when my_cron_job.sh fails (non-0 exit status), no snitch is triggered. DMS notices this hole and notifies you that the job did not run.

1) You can figure this out within a minute, though, just by looking at the wikipedia article about baseball. If it is actually a problem for you, in baseball, a batter stands on home base. Home base is the bottom corner of a diamond of bases, with the other bases numbered first, second, and third, from right to left. The area beyond those bases is the field. People tend to hit towards the left side of the field because people tend to be right handed. Important: the goal in the field or at the bases is to catch the ball that the batter hits, to tag a runner who is trying to run around the bases in order and then back home, or to tag a base that a runner would have been forced to occupy (because the capacity of a base is 1 runner.) 1st base = the first place every batter must run after batting. Right field = a lonely place, and a place closer to 1st base than left field, so not great for a batter to bat to.

2) Absolutely nothing. Sports analogies are usually pointless, but are peppered through "manly" writing. This article is about people who work with their hands, so to a Post journalist, that's infinitely manly.

3) You're lucky it wasn't a football analogy. We know that other people don't play gridiron football, but we love our hail mary passes.

I guess the ehm... how to put it nicely... "Eurocentricness" (?) of the screenshots are a deliberate choice and a real life example of the things you have to put up with as an African programmer?
Lets say all 3 million jump at once and jump for a hour and can fully see 100m at 360 degrees. (Earth is 510072000km2)

=3000000 * 3.14 * 100*100/1000000/510072000 = 0.0001846798

They only cover .01846798 percent of the Earth. so you'd need 10,000 visible meteorites per hour for this to happen once per year. So it seems unlikely.

The fact they both got footage of it is obviously correlated but I also think it drops the probability a bit.

But things like that they are skydiving are not relevant. It's be equally amazing if they filmed it from a building or just looking up in the sky or from a plane. This is the tricky bit I'll just hand wave over. This might override the overestimates above.

Complicated, but looking at the figures and the fact they both got good footage I'd tend towards fake.

I'd be very interested to see a proper write up on this.

That would actually be more stable, since it would rely on a network designed for fault-tolerant redundant store-and-forward messaging.

Instead, each cron job runs an HTTP GET, and later you can view the service's website to see the tests that have requested successfully or haven't responded at all. Unfortunately for your system, if there's a network hiccup, you won't know why your jobs failed and the job will hang on the HTTP call. Also, you're paying for it instead of just sending e-mail alerts to yourself.

I think those connectors are on the detachable baseboard, not the processor board.
Does the thesis hold? It seems to me there are more hackers labs than before. Also they don't convey exactly the same spirit they are still from the same vein, no?
The SODIMM form factor is interesting. I know in this case they are just using it because the connectors are easy to come by, but are there any examples of a computer designed to fit in a RAM socket and do processing rather than just statically storing the memory information?
iOS 4 has an API for sending text messages, doing the same prior to Android 4.4 required using hidden API's. That's the real issue.
Sadly this latest Phrack post reads as lucid as the methamphetamine inspired posts lately on cpunks.org. Phrack what happened man, you used to be cool.

The real reason that there is no more "hacking scene" is simply availability.

Back in the baud days, most BBS hacking was to get into well connected boards and from there get connected to the internet. As most people now virtually have always-on Internet, the value of stealing a connection has vanished.

Another example of availability killing a scene (well, almost dead) is the once-thriving phreaking scene. Groups were dedicated to discovering and sharing the latest info on how to get free phone calls. As the cost of a phone call got cheaper and cheaper, the value of free phone calls also vanished. Who likes jail time anyway? Take Skype for instance... Instant and virtually free international calls. Why would I bother diving into a pit in the cold when it's totally legal AND free!

I would compare the various scenes to ham radio. It's still a thing even though technology has replaced it multiple times over, but the hard cores will still be enthusiastic as ever.

Edit: The Phrack paper being "released" via the Full Disclosure list earlier today was a nice touch.

I was actually asking why don't we keep the peak at 55 from dropping till later. I fully grant this is because I was ignorant of the lower peak at 40.

I should probably have added that most of my understanding in gearing comes from bicycles. I fully expect that my limited understanding there will not necessarily transfer. However, it has built up an intuition that gearing makes a huge difference. It is easy to get a sense that the other components of the equation have the final say, but it is impressive the difference going from a mountain to a road bike.

And again, thank you for the responses. I don't know as that I learned anything I can use in making decisions, but I do feel I have at least learned something.

I think that this article shows a very interesting application of a technique known as “derandomization”. Usually, derandomization is when you take a randomized algorithm and remove all sources of randomness. In this application, we see it only partially derandomized, to great effect: copysets improve reliability by reducing overall randomness, but still leverage randomness to approximate the solution to an NP-complete problem.

I wonder if other algorithms would benefit from partial derandomization?
There's pretty much zero chance of that.
You know, I don't hate that as a user experience. It kinda turns the house into an "intelligent" entity. "Siri, text house, I'll be home in 5 minutes" and it would turn on the lights five minutes from now or whatever you like.
You know, there are, and have been many, many good comic fonts out there. Blambot sells them gives many others away for free. This is where actual comic book creators go for fonts.

Anytime I see someone insisting on using Comic Sans, I gently inform them that Comic Sans isn't even a good comic font, and point them to Blambot, where they can get better ones.

The other thing people should understand about the consolidated feeds is that they only show the aggregated size at the best price at each exchange, whereas the direct feeds show you every displayed order in the book. A direct feed is a firehose and requires significantly more network and processing power to actually make sense out of it.
JDE has a consistent, logical, and totally infuriating table and column naming convention that's a holdover from its System/34 days, so that you're always having to select GLAA from F0911 and so on.

Worse yet, the system doesn't store human-readable descriptions in a consistent manner, so you have to do half a dozen joins just to get to the object names. So JDERef would have provided a valuable service to anyone who needs to talk to a JDE database -- without a handy schema reference, it's just a pile of characters.
By that logic, he also is responsible for making software that people want and for those people wanting it because using it is profitable. Oracle is hardly the only company in Silicon Valley, much less the world, known for ruthlessly pursuing intellectual property claims [it's hardly the only company in the valley with a reputation for requiring developers to dance to its tune, either].

It's not that I am greatly concerned that Larry Ellison's feelings will be hurt. What I care about is that the post is a template for the sort of comments which debase HN's discussions. It's mean for the sake of internet points, and nobody is better informed or inspired to deeper insight for having read it.

The meanness and shallowness of such posts only invites more meanness and shallowness. There are lots of other places on the internet where that provides the majority of entertainment value. It's not why people come to HN.

Specifically "check a signature". Even everyone that knows how to sign fail to really check anything. Honestly, if it aint boiled down to a green or red icon then people are going to misuse, assume security when its not, or just click "yes".

If you get a new public key for someone, and it's signed by someone else you don't know (most of the time this is the case) are you going to bother to utilise that signature to increase the trust? No. Are you going to assume increased trust somehow regardless? Yes. FAIL.

Modify it further, if it is signed by someone you do know what are the chances your UI is going to give you any sort of indication that this is more trusted that other message workflows? And if it doesn't give you any indication (most leave it up to you to check) who's gonna bother to look just passed "your friend <yourfiendsname@company>" ASCII and actually check the key? no one. FAIL.
