This is security 101 right? Or is this normal for a service of this kind? Also are they officially using the Soundcloud API? if yes, is this one of the responses of the API?
The problem is, GNU is a shit name. It's a stupid acronym and it's not obvious to many people how to pronounce it. If it had a better name, I'm sure we'd be calling GNU/Linux that instead of just "Linux".
Their licensing costs. And even then, that's a proforma FY2012 guess from an analyst that's not affiliated with the company. It's worth asking if Wedbush Securities has a short position on NFLX.

This is a company that operates dozens of physical warehouses, employs thousands of people, and pays an astonishing amount in postage fees.

Their licensing costs are surely just a fraction of their bottom line.
Contrary to what you've said here - I've never been a fan of a la carte pricing. I want the unlimited plan. When I get home from work - I generally have netflix on in the background with some documentary or other while I do housework or hack on stuff - same as I'm going to sleep. I probably play 3-4 titles every single day. Clearly a la carte pricing would not be a viable option for streaming 90-120 programs a month.
Ask HN: Looking for feedback on new music recommendation site.
Hi all,

I've just launched a new product (a month or so old, but still very raw). It's missing a bunch of obvious features (related bands, playing music on the artist page, better genre page, etc), but there's enough there that I thought it would be a good time to try and get some feedback.

So would love to hear what people think, good and bad.

The site is called SoundSeed.Me:

http://soundseed.me

and it's basically trying to create the best experience for discovering, recommending, and promoting great music, new and old.

The eventual goal is to create a network of people following other people who have similar taste such that when one person discovers a new artist/band that person can recommend it and word about that new band will spread quickly to people who have similar taste in music.

Anyways check it out and let me know what you think.
not sure on the security implications, but this could have easily been masked through some backend call.
It's still not unlimited (DVDs) since Netflix throttles you if you are too quick to watch and return your movies.
Here's the clickable link:

If you find a "hack" like this on a music website, keep it to your self. If you post about it, they'll try to fix it or obscure it but who knows if some guy at soundcloud will revoke their api key first or some major label dick will initiate legal proceedings forthwith. And then you've just kicked your favorite music site in the nuts, congratulations.

By the way, if you can stream it, you can download it, on any service. One-time use streaming keys are no defense against right clicking. It's just a matter of how much patience you have to expose the underlying URL.
Thanks for the responses everyone. How can I delete this thread now?
Replicas are master/slave, and continues snapshotting is asynchronous. On top of that, we can write a write ahead transaction log. If you put snapshotting and write ahead logs on different I/O subsystems you only produce sequentual writes, which guarantees that you get the most of your IO. Of course, that's on a single box.

For our distributed cluster we have the option of writing the write ahead log to the network "log servers" so you can do it even faster. In this case once ones K out of N log servers receive a log record we acknowledge the transaction. Then eventually the log servers flush it to disk. In this case you are able to write very quickly (you can spin off as many log servers as you like), you store your data in memory in one copy and you're durable.

When I hear about such "MySQL replacement" databases built from grounds up by companies that are just a few months old, I always wonder how complete their support for MySQL feature set is. Do they support every SQL feature/quirk/misfeature of MySQL?

It seems to me that unless it is a complete one-to-one mapping, it is going to be a nightmare to explain what is supported and what is not.

Ask HN: Best product demo videos, which studio, & how much?
What are the best product (web app) demo videos you've seen?

I'm a big fan of Grumo Media (http://grumomedia.com/) and Epipheo (http://www.epipheostudios.com/) short-form (60-120sec) ones.

From what I hear, epipheo is ~$20k for a 120sec video and grumo is $5k per 60sec (60sec min).

Epipheo's Reel: http://www.youtube.com/user/epipheo
Grumo's Reel: http://www.youtube.com/user/grumomedia

So, which videos do you like best (not necessarily only from these 2 studios)?

And, if you happen to know, What studio made them and what do they charge?

I don't think they've cut costs at all. I pay them $9 a month now or whatever. I didn't spend $9 a month at Blockbuster before they existed, and I don't watch very many more movies now than I did then. Might even be less.

I do it because it's very convenient, not because it's a way to save money. I'll probably switch to DVD only from them now and actually start using whatever free streaming Amazon gives me via prime. The streaming selection sucks anyway, I probably watch more on Blu-Ray or stuff I torrent.
I wonder how many Netflix members are also Amazon Prime members. I'm currently on a $15/mo 2-disc/streaming plan. But I also have Amazon Prime. I have the Amazon channel on my Roku and have checked out the catalog a couple times. At a glance, it looks pretty similar to Netflix. It never occurred to me to use it because streaming was included in my Netflix plan and I've already been using it for years.

I'm not so much bothered by the price hike. My price will go up to $20/mo. I'm not going to gripe too much considering how much I use Netflix. But now that DVDs and streaming are separate plans it creates a strong incentive for me to use Amazon Prime for streaming. I'm already paying for it so I can get the free shipping. Now I can change my Netflix plan from $15/mo (soon to be $20/mo) to $7.99/mo and get the same overall service. I wonder if they thought this through.

Hopefully, they weren't low density floppies that they made you punch holes in and reformat as high density.
Given that you have had a problem with both services, do you think the problem is perhaps with your computer/internet connection? I rarely have a buffering problem on Netflix and have never had the audio and video go out of sync.

That's probably because I use HTML Canvas. The balls are currently not animated with CSS but with Javascript (in a requestAnimationFrame loop).
Making a full DOM version with CSS Transitions (or Animations) would be probably better because it's hardware accelerated (especially on iOS).
Android browser has different support/behavior between android versions. Using lot of CSS Animations is in my opinion a little too ambitious (for now), that's why I stayed on a slower HTML Canvas solution.

But for iPhone / iPad, that's not the case, animations work better than Canvas, I have to try a DOM solution to increase these performance :)

I love this post - it's exactly what we're doing... disrupting the boring world of credit card processing. Honestly sometimes it's a bit tough because a lot of people's (and reporters) eyes glaze over the second we mention what we do, and they don't care about the fact that we're solving a major pain point

Consumer is super hot right now... as someone earlier said, it is more likely that you can start a billion dollar consumer business than a b2b play. Some consumer businesses get funded with very little product and no customers (Zaarly, Color, etc). I don't know of any b2b plays that do.

Part of me thought I wanted to join a consumer facing company, but what I've realized is that businesses are consumers too. We get love mail from our customers all the time, from mom and pops to large public companies. It feels awesome and is so rewarding. Good luck on your journey!

I work in medical IT. You'd be surprised how many government sites do similar.

An example would be https://sso.state.mi.us/som/dch/enroll/reg_page1.jsp (You can enter any fake name/email, this is only step one of the registration script. The next page has the captch in question.)

The captcha is plaintext, right on the page. The data from the captcha isn't even sent to the server, it is processed locally via JavaScript.

So, the bots don't even have to do anything, but humans have to input a meaningless number...

document.write('<input size="5" type="hidden" name="rdNumber" value="'+str+'">');

As someone who periodically goes through their archives and moves them to newer media, I found it amusing that my college archives (which were originally on a 1600BPI mag tape) fit on a zip disk, then over the next 5 years everything fit on a CD, then a DVD, then a dual layer DVD, then a BluRay disk.

We used to joke that you could send a uuencoded and encrypted RAR archive out to alt.binaries and then you would be able to recover your data forever. Weird how prophetic that seems to me now.

There are places like NASA who have called on the Computer History Museum for help in getting data off 7-bit magnetic tape.

And as others have pointed out if you save the data but can't read it because the application is toast (Deluxe Paint files anyone?) you have bigger issues. Then you find yourself with an emulator so that you can boot CP/M so you can run Peachtree Accounting so you can read the data from your first lemonade stand.

Its a very deep rabbit hole archiving all that stuff.
What percentage of people exercises enough?
This certainly smells fishy, the client is relying on ARP to assume its OK to reclaim that IP address before it actually gets the authoritative answer from the DHCP server. IP networking does not require that computers submit to dhcp, so depending on how you look at it, it probably doesn't run afoul of the spec.

I'd have to get a more detailed packet capture and reference some RFCs, but given DHCP isn't manditory, I don't think it would be harmful to the mac or network as long as the client's DHCP lease was still valid when it pulled this stunt, otherwise you could get multiple clients claiming the same IP address.

From a security standpoint rather than only revealing just your most recently DHCP-assigned address, you're revealing both the mac address of the nearest layer 2 device and gateway ip of (some nonzero number of) networks you've recently connected to. If a hostile network were to monitor the arp requests to successfully emulate a network the connecting mac had recently been connected to, the IP traffic prior to DHCP ACK that was abridged in the article would probably be sent again. Not knowing what it contained, I can't speculate as to if it would be any different than the network communication that would be done if connecting to a new network.

(Even if everything else was application traffic, I don't anything about the udp/192 protocol for airports, but it may be spoken with assumptions made about the connected network and a vector worth exploring).
I'm still considering the options, but the selection on Vudu is really tempting.

I actually think keeping the DVD by mail with netflix and using another streaming service will probably work best for me, most likely I will just cancel netflix before the change and pay for a month whenever I want a DVD I can't stream.
If you only have a limited collection of images to pick from, then bots could get decent scores by picking at random. A better approach might be to ask users to pick matching images (ie. 2^N possible choices).
Thanks for the answers.
It's not that facts are unimportant and annoying. The trouble arises when both parties know what is being said, but one derails the conversation and makes a big deal and insists things be said correctly- language is then getting in the way of communication.
Why? Furthermore, how do you go about verifying any company's data? It's either deducible from their financial paperwork or it's not.
An every day purchase is a purchase that someone could (be reasonably expected to) make most days. Noone purchases an iPhone for themselves several times a week. Hence an iPhone is not an every day purchase.

You are getting confused because you believe that paying for a service every day make it an every day purchase. You only purchase an iPhone once (although you will possibly buy another iPhone a year or two later.)

Paying off a home loan over a few decades doesn't make a house an everyday purchase. And paying for an iPhone over a couple of years (or signing any two-year contract) doesn't make that an everyday purchase either.
I don't know why people are complaining so much. The company did exactly what they should have - they hiked the price to stay in business and clearly informed their customers in advance. Evidently many people were abusing the unlimited streaming + DVD subscription before and it was not cost-effective for the company to continue to offer the deal.

Percentage-wise while it sounds a huge increase, it is absolutely nothing when you look at the real dollars. My cell phone bill is $100+, ISP is $70+, web hosting is $30+, and I pay $10+/month for many different web services (include many startups I found via HN). How is $8/mo for renting 3-4 DVDs a month too high? Sure, it was $2 before but you can't expect any company to make money on deals that get abused by more than a few.

I'd rather have Netflix charge their customers appropriately than go out of business or start nickel and diming like airlines or cellphone companies.
Around here, that means a kiosk in the grocery store. Sad to say, but the selection is even more limited than the streaming catalog.

I really didn't realize how good I had it when I lived a block from Scarecrow Video in Seattle.
That's a hilariously antisocial response (no offense implied). I understand your signal/noise argument, and that seems to me a smaller, tactical issue. On net higher velocity of interaction is a benefit much like globalized trade is a benefit.

edit: here's an analogy closer to home. when a good, wealth-creating startup raises a second round of funds, diminishing marginal returns to capital means the average capital productivity might go down, but the total product (wealth created) tends to go up.
Did Facebook hijack a developer’s app for its own purposes?
My problem with this announcement is they try and tell their customers what a good deal this is for them when it is obviously not good for them. It's a more expensive deal then what they currently have, if they had been upfront about it and said "our costs are going up due to content providers charging more for their content" or "in order to acquire more premium content for our streaming service we need to charge more" then I think people wouldn't have such an issue.

It's the worse deal + treating customers like they won't notice it that is the problem.

What would the system use for its corpus of images and text descriptions? The corpus would have to be significantly larger than what any given attacker could manually identify. Once an attacker has manually identified an image+text combination, they could store the combination and use it to solve any future CAPTCHAs with the same image+text.

The website is so distracting I couldn't even pay attention to the content. Not only is there a bloody ad in the middle of the first paragraph forcing the text to wrap around the ad, but at most 15% of the above the fold site is actual content. Swaths of the page are devoted to really nothing at all (enormous header and sidebar), ads, and useless whitespace. And are the pennies the author gets for running ads like that really worth making the site look like shit?

Facebook Scam: Casey Anthony Confession Video
It is very much possible to incinerate a chip die within a compact, hermetically-sealed container without releasing smoke or other tell-tale signs.

Yes I know it is. I just don't think you are going to homebrew it out of model rocket igniters and magnesium ribbon.

The US and other wealthy nations' armies use self-contained modules like this in their encrypted radio equipment.

And they're not going to jail for releasing smoke in a federal crime lab.

If you view law enforcement officials as your enemy, using unmodified off-the-shelf equipment, regardless of its rarity and expense, is simply stupid.

The great majority of the off-the-shelf equipment is not even designed or made in the US. It's used by the US govt as much as anybody else.

Back doors are a near-certainty.

Really? Name three hidden back doors from the US government. I can only think of one or two, making them pretty rare.

Sometimes back doors are found, so it's not that nobody's looking: http://www.nextgov.com/nextgov/ng_20110707_5612.php

I think your post nailed what's intriguing me right now: Netflix did a terrible job communicating these changes. It's odd to me to see such a large, well-liked company spend so much of their social capital (brand loyalty or belovedness) without better messaging.

For example, in an age where bundling is ubiquitous, I think Netflix needed to have a better explanation for why one service is being split into two and why there's no discount for joining both. Netflix needed to do a two-pronged approach -- here's what we're going to do for you, and here's what you're going to do for us. We all understood the latter (we're going to pay more), but nobody gets what Netflix is offering in return.

There doesn't seem to be anything in that article that suggests that the military perpetrated the attacks. Would you care to explain further?

EDIT: While a researcher with the US army was accused, there doesn't seem to be any evidence that he was actually responsible, and there is doubt over whether the anthrax he had access to was the parent of the spores used in the attack. Besides, even if he did it, saying that the US army is responsible for something implies high-level planning to do it. It's like saying, if someone in Anonymous works at McDonalds, and used a computer in one of their stores, that McDonalds is responsible for Anonymous's attacks.
