The centralisation helps again here too though.

The central server has access to the entire file, and hence can compute the hash of any arbitrary chunk. Challenges/verifications don't have to happen all that often ([1] indicates they are looking at once a month) so creating a unique challenge for each user shouldn't be too compute intensive.

For each known user:

- Central server chooses random chunk of each file it wishes to verify the user still has. This could be any length from as long as the hash function to the whole file size and could be offset any number of bits.

- Client is asked to provide the hash of the chunk using the file stored locally.

Precomputing hashes for all possible chunk permutations would take up substantially more space than simply storing the file in the first place. A bad actor would need to store the hash for all the possible chunk lengths starting from every possible start location in the file which is in the order of O(n^2) where n is the stored file size (500GB in this case). For reference that would be about one third of the entire 20PB archive for a single 500GB chunk if using a 256 bit hash function.

Haim Schoppik and Chris Maguire: Left Etsy at the same time (https://blog.etsy.com/en/2008/a-fond-farewell/) to create Postling (http://mashable.com/2009/08/11/postling/)

Kalin is still there as CCO. Tarbell also looks like he's still there too?
Were all of them fired or just the CEO?
I don't think that's unique to the Hispanic community. I'm from Scotland and our tourism industry thrives on Americans who identify as Scottish or Irish even after many generations have passed. I would imagine this is true for Germany and Italy too.

Robert Kalin lists himself as CCO (compliance officer) on Linkedin. It looks like both Haim Schoppik and Chris Maguire are no longer with the company as of August 2008. It looks like Jared Tarbell is also no longer working at Etsy either.

Seeing as the company has raised 8+ rounds, I would hope they had the sense to cash out at least some of their shares.

This probably isn't quite what you're looking for but, Ford MyKey exists: http://en.wikipedia.org/wiki/MyKey.
You don't need to explain to me why the current 'standard' arrangement is designed to please and protect VCs at the expense of engineers. But that's exactly why we have a proliferation of VCs and startups and a 'shortage' of engineers willing to work for them. The classic argument for liquidation preference is because VCs are putting up money, but so is the engineer if he's taking a salary cut, and the only reason you find it ridiculous that I suggest engineers get preferred stock is because you are stuck in an old school mindset where financial professionals are in charge, and they loop in a few chosen engineers (founders) to bamboozle the rest into bad deals, and "work hard because we're a startup and have ping-pong tables". Not surprisingly, you are VP of engineering and trying to hire, so you're invested in the status quo that rewards founders and VCs. I think the echo chamber has made startups so 'cool' that I decided to bet against the herd mentality and get a good deal from a big tech company. I'd love to re-enter the startup industry at some point in the distant future, I just want to challenge the status quo and see an arrangement where engineers are actually partners and true, first-class owners. If this scares away some VC money, good, there are a lot of questionable startups out there already, it would be better for the industry as a whole if some of these startup engineers started collaborating instead of every single one needing to be founder or at least VP of engineering, because the only engineers willing to work for less than that are naive or inexperienced.
Real life is not a film. We're talking about a disorder that's likely caused by a traumatic event and is associated with _proper bad_ anxiety. You don't necessarily respond to logic in those cases, you respond to things to which you have a strong emotional response -- and which will, hopefully, comfort you.

Reversely, when you see someone in that state rushing for the door, knowing they'd be helpless to deal with actual risks, 'de-escalating' is the least of your concerns. "I must keep her safe, with me" is the only thing in your mind.
I don't believe you actually ever heard anyone say that.

I Came Undone: One Woman's Horrifyingly Real Experience with Burnout
No, that would be too much for a DID patient and could lead to further splitting (creation of new parts). First step is to teach them to stay grounded, to stay present and not take the easy path and dissociate (i.e. go away). When struggling to stay present someone with DID may exhibit OCD patterns -- scratching, grabbing, fiddling with fingers etc. -- all without realizing. However, when this happens there's usually some level of co-consciousness with a part that is suffering or has OCD. So in this case the OCD behavior would "belong" to that part while some other part is "out" (they'd actually both be "out" at the same time). It's a very complex disorder.
Everything taught in high school, except writing, is trivial, so the homework doesn't really matter.

For non-trivial material, I found homework - ie. doing brutally painful difficult work by myself - was the only way I learned anything. Structuring that material in better ways is what separates great teachers from the rest.

As a math and science teacher, your focus should be on teaching non-trivial material, not the social ramifications.

His short position added information to the market. At least in theory, other investors could have asked "Why does this person think that this company is less worth than it's current value?" and done their own research.

The short position provided incentive for him to expose the fraud publicly. It would have been nice if he'd done this research and told everyone about his findings out of the goodness of his heart, but that's a lot of work for little personal reward. The ability to short provided an additional incentive to make the information as public as possible.
For all of the New Yorker's clout in journalism, sentences like the following make me wonder where their editors are. The run-on and sea of commas is atrocious! It's not the first time I've noticed this in the last few days either.

"Hassabis, who began working as a game designer in 1994, at the age of seventeen, and whose first project was the Golden Joystick-winning Theme Park, in which players got ahead by, among other things, hiring restroom-maintenance crews and oversalting snacks in order to boost beverage sales, is well aware that DeepMind’s current system, despite being state of the art, is at least five years away from being a decade behind the gaming curve."
No, but can I work there? At least for a little bit? Always wanted to do something hands on.
You can control for genetics by running a controlled study, where you take a group of people and randomly assign some individuals to exercise and some individuals not to. Then, by construction, the exercise and no exercise groups are drawn from the same genetic distribution. I'd be very surprised if no one has tried to do this, but there's probably a limit on how long you could run it for.

There's also the possible "placebo effect" confound, which is a problem for both a controlled study and a twin study, but might be a bigger issue for the former (where participants are told to exercise) than the latter (where participants exercise or don't exercise of their own volition).

I expected some backlash as Jessica made here "hey guess what, I'm a co-founder of YC and I was as important as anyone" tour complete with this post. Glad to see it wasn't that bad.

For those that are put off by Jessica doing this: she is not going to get credit unless she takes it. She deserves it, she's earned it, and the historical record should indicate it. Good on her for taking the FFC and this post (and a couple interviews) to set the record straight. The story of YC is the story of a female founder and it's critical the record reflect that.

Yes, but that stuff is hard and error prone.

Immutability is easier (safer, more correct) on the whole. I think both Rust and Clojure take a good stance on mutation.

Only for anecdotal evidence, my ad-hoc immutable (lots of copying) ETLs performed better than the mutation happy ones. The GC was able to throw stuff away faster, the code was cleaner, kept only what it needed. The gaussian circle of confusion was smaller.
Not all military satellites require some outstanding capabilities - and military does launch cubesats and other small-scale devices today. Reminding that if 50 years ago military requests pushed boundaries of technology, today commercial applications are so demanding - and command such a large market - that it is military devices which piggyback on RND results of commercial ones.

Yes, you may always want a unique, expensive, cutting edge satellite. But you won't always need that - military doesn't directly set the goal to spend as much as possible. X-37 demonstrates a lot of capabilities while being much cheaper than previous reusable space vehicle. So with launch costs going down other, cheaper opportunities open - to everybody, including military. That's beside the idea that cheaper rocket doesn't mean worse rocket, reminding Japanese cars of few decades back.
How many pop cans are damaged or destroyed in shipping?

Any rate at all is higher than is tolerable for rockets costing many orders of magnitude more.
Author here! That's certainly an interesting feature that could be added. I have on the future list to support sending responses back via AMQP. Your callback scheme isn't much different than that.
There is also schizotypal personality disorder (http://en.wikipedia.org/wiki/Schizotypal_personality_disorde...), which can look a lot like schizophrenia and can occur as a comorbidity to DID or borderline personality disorder.

I had a friend who I thought was borderline, and later suspected to have DID. She sometimes said delusional things like she thought she was an alien, or that Jesus was inside her, or that she was a reincarnated dolphin, etc. Other people told me she would get weird in conversations, a lot like the "react oddly in conversations, not respond, or talk to themselves" description in the Wikipedia article. Stuff that schizophrenic people do.

When I asked about it, she said she realized that it didn't make sense that she was a reincarnated dolphin and that she didn't know why she believed those things. Schizophrenic people don't really have that kind of self-awareness.

Fascinating, thanks for your reply. I can imagine photos to not be enough. For me the association is strongest with scents and noises/music - this gets me back to a memory the fastest. I guess this is similar with this disorder?

What's hard for me to imagine is how this disorder works physically, at least with the primitive model I have on how the brain works. The synaptical connection are still there, otherwise the person would have a permanent memory loss, right? So my guess is it has to do with brain chemistry? If that's the case, couldn't it be medicated?
Ask HN: How do you reject a startup job offer without burning bridges?
In the past month or so, I've had job offers from two wonderful startups (co-incidentally both are YC companies). While I've found both the companies and the teams highly motivated, I made my decision to join the slightly larger of the two startups, mostly because I come from a large enterprise software company and probably don't have the confidence to join the smaller one at this stage.

Now, despite of me expressing the reason for rejection to the smaller company, they have been trying to convince me that I might be backing out due to imposter syndrome, which is clearly not the case. It has been three days and despite of me rejecting the offer, the co-founders of the smaller company have been calling me in.

Given the situation, how do I reject the offer without burning bridges ?
I doubt it's much different than school. We were all fast before an assignment was due. Very few of us maintained our productive habits everyday.

So the final product has just as much to do with work ethic as ability.

You're not getting the point.

To me, when I read this words, it paints a very nice picture. I picture someone volunteering to take out waste, use zero emission transportation, and then help out a local farmer. I like that, a lot.
Realistically, what could be done about it?

Serious question. I had the same reaction as you to these comments. It seemed like Jessica was getting a lot of skepticism relative to what PG or one of the male partners would have received from similar claims.

But I don't know how I would change things. Any suggestions?

Meth is an amphetamine like Adderall. I'm pretty sure using a strong stimulant just increases the negative (and positive) attributes already in people.

This sounds like the nonsense about bath salts making people murderers.

It's all on a spectrum with DID being a more "serious/complex" form of PTSD. A DID patient experiences PTSD symptoms, but also symptoms you won't find in PTSD patients.
I would look askance at any company trying to imply there's something wrong with you for not accepting their offer. Sounds like you made a good decision.

Not sure what "reason for rejection" you gave them initially, but none is needed. "Hey, I appreciate the offer but I've decided to go elsewhere - would be cool to stay in touch" is plenty.
You're being far too literal in reading this as just video storage. It's more than that.

The key is that selective editing of any narrative can create any story you want.

That, and costs of storage are falling tremendously. I remember when the idea of having more than a few minutes of video on disk storage (I had 2-6 GB at the time) was ludicrous. I've now got 88 GB of video, the bulk of it YouTube or Vimeo content I've saved, largely lectures and documentaries. Being able to review that on demand is quite useful.
The context here is NASA moving slowly and the possibility of SpaceX launching without their involvement. Can you think of a single customer for that?

I congratulate anyone that can get funding toward making their dream real. However after spending a year riding an electrically powered bike, I would be curious how this will address/handle the following things that finally caused me to hang up my wheels:

1) As you get older, particularly if you work in tech, you will notice your wrists, elbows, and shoulders getting a little sore. Ergonomics can go some way toward minimizing that, but riding a bike in any kind of traffic will put a lot more strain on you. Any kind of cushioning/shock absorbers/breaks?

2) Mentioned the electric assist. Is that going to be an option for these, or is your audience only folks who can ride a regular bike from day 1? A number of folks I've run into wanted to switch to a bike from their car, particularly during nice weather, but wanted some assurance they wouldn't get exhausted halfway there. The assist made it possible for me.

3) In the same vein, some way to fold this so it can be carried in a small car or some special rack so it can be carried by car? Particularly for a commuter audience I would think you would want the ability to hop a car or bus or train for part of the ride?

4) Lights rechargable? How many recharge cycles? Batteries replaceable for the lights/sensors/bluetooth?

5) Someone has already mentioned a smart helmet. I know there are a couple companies working on those, but are y'all working with any of them to incorporate a handshake so you can possibly trigger things at the best time?

6) Lastly, any thoughts to collision avoidance signals for other traffic? Something where it senses a car or other vehicle is getting too close and either hits the horn or flashes a light(s) to try and get the driver's attention?

Thanks in advance for your time.
I ended up by learning and building myself. Just have to keep my burning rate really low. I've been working on my project for around two years now. Hope this time I can satisfied with what I'm building and actually put it onto app store. Thanks for your story.

If you don't remember events due to not paying attention (being "tuned out") that is simply not the same as not remembering who you are or who your boyfriend is.

In the former case, you don't remember the events because you were neglecting to commit them to memory. In the latter case, you have the memory, but it is temporarily inaccessible --- and comes back.

Memories that you did not form because you were tuned out never come back because they don't exist. For example, you will never recall the words of the bore whom you tuned out at last night's party. You nodded your head but were completely occupied with thinking about something else.
