Film guy here. It wouldn't be that hard to fake. angle of the sun/direction of shadow is easy to keep consistent, motion blur is wholly automated these days (as in, select start/end frame & position, and motion blur will be on by default in most programs with excellent results). Although the camera is moving slightly, the distinctive and structured shapes of the batting nets provide perfect tracking points for trajectory mapping; alternatively, you could shoot at a higher resolution from a tripod and then introduce some floaty movement afterwards, windowing onto a smaller frame at 1:1 resolution. Making the nets bounce is trivial, you just need a couple of takes from the same camera position. As long as the light isn't changing, it's astonishingly easy to key stuff in and out from different frames - typically used to remove people or vehicles, but just as easy to introduce them. So it's possible that this is a film school/enthusiast project; I'd say it could be done in a single day on an average workstation.

On the other hand, the guy may just be a good batter. Bouncing a ball off 4 nets will rob it of a lot of speed, and if one practices a lot it's not that hard to get a rhythm going. When I was a teenager I used to kick a soccer ball off a wall for practice, and my aim was kick it back 100 times, starting over from 0 if I lost it. I wasn't all especially good or dedicated, so I have no problem believing this would be achievable by someone who's serious about the sport. Jugglers have to perform far more complex movements at much faster speeds, for that matter. Finally, for all we know this could have been the 10th or greater attempt to pull this off.

So either is possible. I don't feel like downloading the video and stabilizing it to do a windowed frame diff, but if you wanted to get forensic on its ass the best place to start would be to measure the # of frames between hits, because you're got a nice marker from the noise of the bat; if it's exactly the same more than 3 times in a row suspect a fake, likewise if you see a repeating progression of frame intervals like 23-25-24-23-25-24.

I dont understand why facebook gets a green card from the blogosphere, while nobody of its competitors or any other top-10 website reaches anywhere near this sort of evilness. Myspace didnt ban facebook ads, google doesnt ban facebook ads, hi5 doesnt, the majority of social apps advertise other apps; why is it "understandable" for fb? That's not a good way to build "open" app ecosystem.
Can anyone shed light on where the GIL winds up hurting you?

According to this paper [1]: "Thus, in all cases, the single global lock semantics seem fundamentally compatible with both lock-based and transactional memory implementations."

You probably are even less interested in adding your credit card, but if you want, there's a "Payment Information" section if you click on the "Account" button dropdown by your apple id in iTunes.

I just changed my password to one more unique (I was reusing it elsewhere), and finding the place to do so was surprisingly hard to find (IMO, it's harder than adding payment information).
Just wanted to mention that those aren't the same video I'm posting.

I found the one I posted a little better on the explaining side, since it is 30mins long, and those link you posted lead to a 10min video.
Will there be some sort of seasonal/occasions model in addition to the monthly one? Because I could see this being incredibly useful around Holidays (i.e. Christmas) and having an automatic Christmas card generated and sent out to all my family and friends.
Reference counts could be stored separately from objects and migrated to the thread that modified it. Or several reference counts for the same object could be used. Has this been tried?
yup that's right, at least me and most of the guys that work for Fork (the company I founded after Prey took off). however there's lots of contributors from Europe, the US and Asia.
I find it terribly annoying when the solution to a language problem is "Write an extension". It's a cop-out.

Java, .NET, various Lisps, and I'm sure other systems that I don't know off the top of my head have solved the problem of true threading.
I wasn't thinking about social network sharing when I was referring to social features - I was thinking about social features within the community.

I'm an amateur photographer, the work that I do is of interest to other photogs, rarely to my "real life" friends. Flickr's Groups, for all its faults, allow me to keep up with photographers of similar interests, and they with me - no amount of "Facebook/Twitter/StumbledUpon/+1" button integration will get you that sort of interaction.

There are really two sides to this that I can think of:

- Discoverability: can you discover the work of other people easily, and they yours? 500px has a wonderful way of measuring top uploads and exposing the best work to the world in a beautiful way. Flickr has groups where you can reach out and interact with photogs of similar interests. AFAIK SmugMug has very little in this regard.

- Interactivity: what can you do once you discover interesting, good work? On Flickr you can comment, you can add to group pools (to the collective groaning of everyone, but hey), you can fave, you can give all sorts of feedback. Similar for 500px. SmugMug is not nearly so tightly integrated in this way.

It's very much organized to be individuals of portfolios, there's not a distinct feeling that you're part of a greater network rather than simply looking at a single photographer's work.

I really apologize for the anonymity. We just can't announce anything yet, but we can talk about quite openly it if there's an opportunity over email.
I don't mean to be a downer/naysayer, but how can you argue that photo printing is a growth industry?

I run an ecommerce service for wedding photographers and know a lot of other people in the industry. From where we sit, the consensus is that people are ordering less prints. All the growth we're seeing is from album/book sales and digital file sales. 5-10 years ago, a portrait photographer could charge a $100 sitting fee but still make $1,000+ on print sales. That is now hard/impossible. Everyone simply asks "Can I have the files on a disc?".

I can't see how it would be any different for the general consumer and their images. People get their utility from seeing the image on Facebook. My mom is 63 and she looks at our family pictures on FB every day.

Wont the generation that is accustomed to (and prefers) tangible prints be dead in 30 years?

Given Apple's security practises are more Microsoft-2001 than Microsoft-2011, I'd hazard a guess that there's some sort of 0-day exploit hitting iOS devices themselves.

Scott's not dumb though to fly without antivirus/firewalls on his own PCs.

Your iPad/iPhone, on the other hand, are almost certainly running no antivirus and no firewall. Because who needs such inconveniences, eh?
And how do you keep this consistent across different objects? IE object A and object B are updated at the same time, going from generation 1 to generation 2. I am on a remote machine reading from the cache. How can I ensure I don't get a view where I see object A at generation 1 and object B at generation 2?

IE the basic point I am making here is that MVCC does a lot of relatively complicated stuff to handle this for you. I don't disagree that you are gaining a lot of power at your remote nodes to do things that would increase performance, but for 99% of applications I think it a huge amount of work for a small amount of benefit.
Sorry, didn't look hard enough then, thanks :)

No, I really don't think that it is disproportional. Sam Odio hasn't apologized let alone returned the money. In fact, he just tries to justify his actions. I would say it is likely that this is symptomatic of his ethical and moral attitude in general.
Rubinius (in the current 2.0 betas) has removed the GIL as well. In fact, the only Ruby that still has a GIL is MRI. MacRuby, JRuby and Rubinius (as of 2.0) all have threading without a GIL.
Their blog hasn't been updated since June http://blog.joindiaspora.com/ , but the Twitter feed has a couple a features they've added recently https://twitter.com/#!/joindiaspora They just sent out a survey to early adopters asking them about how they're using the service and what they should focus on.
So is this basically a relaunch of PicWing? It seems like pretty much the same thing, just more expensive?

One other point. Isn't it a little odd to use a testimonial from the lead investor of the service in such a prominent way without designating them as an investor?

There's a difference between units sold to retail, units sold to customers, and units that are actually in use by customers. I'm also curious if they count Nooks, which are not always used as tablets even though they run Android.

Don't get me wrong, I'm rooting for non-Apple tablets. But in reality, there don't seem to be that many in the wld yet.

As a solo founder myself, I just want to congratulate you on launching what looks like an interesting and promising business. I'm particularly impressed you got the domain name housefed.com. Is there a story behind that?

P.S. I'll definitely check you out when you get into Canada.
I completely agree. Most of the web 2.0 picture world involves pictures sent digitally to all of the social networks and smart devices. I think this leaves out an important market or two in the photo sharing industry. Most notably, the technologically unfamiliar (grandma and grandpa), and the photo purists (people who want physical prints for display, but can't be bothered to print out inferior quality shots on inferior printers). Many popular photo sharing services degrade image quality for transmission and storage. (See: Facebook and iPhone)

The frustrating thing with all the "sales" numbers I've seen for Android based tablets is that they all seem to mention the units _shipped_, but not necessarily sold to consumers. The original article quoted by BGR still says "shipments". Is this just a semantic difference and those really are sales? I honestly can't figure that out.

And do those numbers account for customer returns as well, since there do seem to be a certain amount of anecdotal evidence to suggest that Android tablet returns are abnormally high.

Furthermore, there also seems to be a large quantity of super-cheap, and super-terrible Android based tablets [1]. Are those counted in the same numbers as better ones like the Xoom and Samsung Tabs?

I'm not trying to be snarky, just genuinely curious if people are actually BUYING Android tablets (and keeping them).

I suppose it's people being tired by the whole "hacker" hoopla, especially when people use the term to compare their e-peen, but also when the media confuses hackers with crackers.

To me, the hacker/cracker thing is just a lost battle and thus a big waste of time.

That being said, I'd only use "hacker" in the original sense, i.e. the hacker philosophy about exploring, learning and teaching. To me, a person with no clue about cars that learns to fix it themselves is by definition a hacker.

You all too often see people pulling the e-peen thing on the net, which I find sad, as it's also just another waste of time. The "correct" use of the term hacker is just a pretense imho.

In the same vein of whining and bitching: has there been another influx from reddit lately or is the cooling effect (or what it's called) only gradually noticeable?
I've noticed that I'm more disappointed with the content and comments on HN lately, even more so on reddit obviously.

OK, so now you've laid out what happens if everything goes perfectly. Now list what could go wrong and your best estimates of their likelihood, and tell us what a mixed success would look like.
I think you're comparing the wrong things here. People ask for the photos on disc because they can then go print as many copies as they want for a fraction of the price.
That sounds like a bug... turning them off worked fine for me. Have you filed feedback?

I think your logic is somewhat off, as you are considering playstation 1,2,3 to be different, while iPhone 1,2,3,4 are in the same bucket. Also consoles are generally a one per household thing. Phones aren't.

You're getting downvoted because he's not implying that installing Prey makes him a hacker. He updated his post as follows (possibly after you posted your comments?):

I don't see the meaning in a graph comparing tablets from 8 months ago to game consoles from 20 years ago.
Yeah, no. If I have a dictionary of 100000 words, then each word represents about 17 bits of entropy. If I have three words, that makes 3 x 17 = 51 bits of entropy.
People are ordering fewer prints, but which percentage of the prints they are ordering are pictures of kids for grandparents? A significant proportion, I bet.

Anybody who has walked into a relative's house and seen their gorgeous DSLR emailed baby picture printed on some crappy paper by some crappy printer proudly displayed has died a little inside.

The reservation I have about PicPlum (and, I suspect, why I never got around to signing up for its previous incarnation, even though I was interested in principle) is the fact that you still have to do the curation - a step that in practice I would forget. I would be interested to know from somebody who has signed up whether the service can be configured to remind you to send it some pictures).

[edit: grandparents might be online, but they seem to have a perverse need to stick pictures of their gene pool on the fridge anyway. Hell, mine have an Internet updatable LCD frame which sucks new pictures over all the time and still they print out for the fridge, handbag etc. ]
Smart: YC-Backed Picplum Targets Parents with Photo Printing and Sharing Service
The tech may be similar, but they're fundamentally different markets. Almost everybody needs a phone, but tablets are (currently) luxury items; and carriers play a far smaller role in tablets, and often none at all.
Even if Daniel has given as much money as Sam Odio took from it, a net damage has still been dealt to the card. People (for instance, myself) will be less likely to give money as a result of the publicity Sam Odio has generated for himself.

To say nothing of the condescension and insults Sam Odio has heaped upon people who thought it was a pretty neat idea. He would still have a large amount of apologizing to do, assuming added what he took.

First, I wish you the best of luck on your success. But, quite honestly, I loathe these popularity contests. These contests are thinly-veiled attempts at free marketing which are easy to game and indicate no real social proof for those who won. I feel badly for individuals who get caught up in these multi-round competitions because a lot of energy typically gets spent on spreading the word for this contest instead of spreading the word about their product's value.

Unfortunately, I'm not interested in doing promotions for Salesforce so I won't be sharing or subjecting my friends to the contest. Don't take it personally, please. But I'll at least throw my own vote in the pile for you. :)
Exactly. Now, this isn't to say that Google couldn't create new solutions to some of these problems, but I get the sense that at its core, Google+ isn't going to be about discoverability per se, but about, as you say, connect with people you already know.

Flickr's search is actually quite robust and amazing. I frequently use the Creative Commons archives for my work as a writer. It's a fantastic resource.

Flickr might be dying, dead or stagnant, but I don't think that its replacement will be a slightly rehashed Picasa. Instead, I'm guessing it will be some sort of new network design that is able to surface photos from multiple sites and accounts and identities.

> Apple's new-device-detection algorithm doesn't seem to be perfect - I was vacationing and bought an app, and it was flagged as a new device (I got the mail for my purchase), despite it being the same one I've been using for a few years.

I have had this happen with Steam countless times, it's made me hate the Steam Guard system. I have a long complex password for Steam and I don't play online so my account isn't high risk at all.

However I use a number of different browsers on different machines and reset them frequently. As a result, almost every purchase I've made through a browser from Steam since that system was implemented has required me re-authenticating the "new device".

Personally, I'm not a fan. I'm positive it would get an even worse reception from the general public, too. Steam users aren't necessarily savvy but they are typically willing to jump through technical hoops for a particular endgame. I wouldn't say the same for iOS users, by and large.

This is a tricky one. Increasing security without adding complexity or alienating users that have grown used to the current system is very difficult. I'm not ready to jump all over Apple for this, it's not a problem with an obvious & popular solution that they are just choosing to ignore, this is something every company in the world is struggling with right now and they all have a different way of combatting it, each with their own unique pros and cons.
It's highly desirable to be called a genius, but in general people calling themselves geniuses are looked down upon.

I think among people who do use the word "hacker" to mean someone skilled with computers, it's considered poor form to call yourself a hacker but high praise to be named a hacker. Eric Raymond wrote long screeds about this way back in the 90s when people still gave a damn about him.

Personally, I call somebody who is skilled at breaking systems a hacker. The guy who discovers how to Man-in-the-middle attack an SSL connection is a hacker. The morons in black trenchcoats and leather fedoras who then download a .EXE to automatically do just that and harvest passwords at Starbucks... are fucking scum of the earth script kiddies.

I'd recommend that you don't rely on only color for the post and following telltales. Use color plus something else.

u->oscar
oscar->u
u->oscar->u

For the not shared, shared, and yours icons, in addition to color you could:

Not shared: only the center circle, no surrounding dots.
Shared: center circle plus surrounding dots.
Yours: center circle, surrounding dots and a line circle around that.

Extra fancy if Yours icons only get dots (inside the line circle) if they're shared posts.

EDIT: Formatting.
See here I am a little confused. I never really understood why one couldn't do this:

construct an equilateral triangle atop the angle to be trisected
bisect any side, construct a new triangle with said 30deg angle giving a line segment 1/sqrt(3) of the original eq tri
bisect the new 60deg angle, constructing a new 30/60/90 tri

voila, 1/[sqrt(3)sqrt(3)] == 1/3. You have trisected a line with a compass and unmarked straightedge
