A quick search says that 71 people were shot or killed in the massacre.

If a gunman were to go out every day and shoot up a movie theater of say, 110 people, for the next century; the death toll[2] would be:

(110 * 365) * 100 = 4015000

Which is a little more than 4/5ths of double the annual fatalities in 2009. [0]

[0]: http://www.cdc.gov/nchs/fastats/deaths.htm

[1]: Of course, if our hypothetical gunman only targeted movie theaters, going to any single movie theater on a given day might be a risky proposition. If someone can find the number of people who see a movie every day in the US I'd love to know.

[2]: Actually, shot != death; so the death toll would be lower. Of course then you have to think about things like permanent debilitation and traumatic memories, not to mention healthcare costs.

According to this table:

http://www.reddit.com/r/news/comments/wv8t1/comprehensive_ti...

There were 60 victims, and 38 have been released from the hospital. 8 are still in critical condition, so we can't know if they'll live or die.

I'm going to assume, just for the sake of being on the pessimistic side of estimations (I don't actually believe this.), that everyone in critical care dies.

So presumably that would mean:

60 - 38 = 22.

Depending on the lethality of the shooter and random chance, the death toll may be as much as 2/3rds lower than the total number of those injured.

EDIT: This post originally said:

Which is still lower than the amount of people killed by heart disease in a single year here in the US. [0][1]

I can definitely vouch for getting value out of simply tailing a log of new signups or just refreshing our admin of signups every few when we were collecting a lot of email address.

The ones that look valuable stick out like a sore thumb and emailing them custom content is way more useful than generic gmail accounts.
Luckily the ouya is going to do just that, I wonder if Google will purchase them if they become profitable (or even without profits it'd be a smart acquisition for them and would give games companies more confidence in the console and building games for the Android platform in general) .
Oh, I don't mean to demean the field of Quantum Information. Especially, I find it really useful to run through the double-slit experiment by labelling one slit as |0> and one slit as |1>, and then going through both slits comes out as sqrt(1/2)[ |0> + |1> ] = |+>, which has certain "off-diagonal terms" in its "density matrix."

If all that formalism is built up, you can have fun working through when these off-diagonal terms exist and when they do not, especially in cases where you take a new qubit as |0> and then entangle it into the system with a CNOT gate, where you get |00> + |11>.

If folks are confused by the above, I have begun trying to explain it here: https://github.com/drostie/essay-seeds/blob/master/physics/d...

It's really kind of rough (in particular I'd like to use proper HTML subscripts rather than Unicode subscripts eventually) but it should be intelligible to a bright student who wants to know the basic ideas of QM.
No. Either your first priority is delivering value to your users or it's not. Craigslist has changed from one to the other.

Padmapper isn't the existential threat. It's CL's failure to keep improving.

Taxi Penang
After deciding the region to visit and verifying the hotel accommodations, it is shrewd that you simply ask the hotel customer service on particular details such as the usual rate to cover a taxi Penang within the airport to your hotel. You can also ask on specific taxi operators to ride in since there is certainly drivers who scams foreigners.
Dropbox employees are custodians of that data. If they can’t protect it for whatever reason Dropbox is pretty clearly at fault. Their policy on how employees have to treat data is not good enough.

If a user had re-used a password Dropbox wouldn’t be to blame. But we are talking about a goddamn employee here. That makes Dropbox directly to blame.
It will be interesting to see what this will do to the push ad craze on Android (http://www.appbrain.com/stats/libraries/ad : the #2 and #3 ad networks in terms of apps are push ad networks. This is measured by total number of apps, these ads do much less well on installs as professional developers know better than to include this in their apps.)
The new terms only say that it's not allowed to imitate system notifications, but it also says that it must be clear to the user from which app an ad is originating. This is currently not the case with most push ads.

I've been able to get most of the old gmail interface back by following Jason Crawford's recommendations:

The stuff I cared about anyway. I agree it is sad.
> A/b testing, using usage metrics to drive decisions, customer development, lifecycle email marketing

Yes, but I've been pleasantly surprised at the clueyness of of more than a few big-name clients recently.

> Or for more dev focused stuff, unit tests, Selenium ("the best technology that I'll never use"), code reviews as a routine practice, reproducible server setup/deploys, etc.

For deployments at least I've been blown away by the range of configurations I've seen. Everything from "git push heroku master" to "ssh into these three machines, run svn up, restart apache, merge dev couchdb to live, copy paste these 80 sql patches out of a file into the terminal, sacrifice a hamster to Amon Ra and cross your fingers."
I genuinely do wonder whether or not this will change anything for (current) Apple customers.

The multi-factor apps I use are more secure, assuming they are built correctly. Even if they are not secure, I think they are, and that's a relief for me. I want to provide that to my users.

Exclusive license means exactly what it says. You are giving Craigslist essentially full copyright ownership over your listing. The only exception is that in moral rights jurisdictions you aren't giving them moral rights.
If mixing perspectives is better for boards, does it mean they would benefit from putting more anarchists, Inuits and children on board? They also deliver other perspectives.
You can transfer commercial rights to someone else, right? Just not moral rights? Or am I missing something?
SWTOR down the drain
So if you are a self-published author I guess you had better not sell your books on Craigslist, using a part of the blurb posted on the back!
It's a bit more complicated: We don't have copyright as the americans do, it's split in "Urheberrecht" which is the part the the creator owns and cannot license or sell and the "Verwertungsrecht" which is the right to use the work.

Urheberrecht encompasses thing such as the right do defend against modifications that go against the spirit of the work or the author or against defacing it, the right to be named as the creator (though this one can be waived by contract depending on the circumstance) etc. The Urheberrecht can only be transferred by inheritance.

The Verwertungsrechte is anything related to the use of the work, such as selling, buying, (sub)licensing it.

Please keep in mind that this is a gross oversimplification and IANAL. The copyright situation is complicated enough for experts in the field and cannot be explained in a short post I guess :)
When I was a kid, several of us in my neighborhood had vials of mercury that we enjoyed playing with. We didn't do any chemistry experiments with it, though--we just enjoyed watching solid metal objects float on it, and taking it out and feeling how weird it felt rolling around in our hands.

This was in the late '60s and early '70s. I don't remember where we got it, but we didn't keep it secret, and no adults (parents, teachers) freaked out if they saw us with it.

I wonder what would happen nowadays if a kid brought some mercury to school to play with?
That's interesting! Do they pale in actual complexity of the code or in terms of sheer code size?
Ad Walls
Forcing the user to click on ads or submit personal information for advertising purposes in order to fully use an app provides a poor user experience and is prohibited. Users must be able to dismiss the ad without penalty.

Does that mean "offer wall" companies can't advertise on Android platform?

The top gradient is from transparent to red, the bottom is from rgba(255, 0, 0, 0) to red.

Notice how the top gradient fades through grey - this is because 'transparent' is a synonym for rgba(0, 0, 0, 0).

I still think if they'd removed the HDMI out, it would have got better reviews. The inbuilt amp and connecting to a TV are pretty much mutually exclusive, and everyone focused on the latter then wondered why it cost 3x as much as something that connected to a tv but didn't have an amp in it.
Any links? Where did you get it?
Can't wait for RDS to plug into this.
I think it only means you can't show an offer wall and say "you have to perform at least one action to continue". Showing offer walls that leave all actions voluntary is still fine, the way I read it.

This move is against the grain of other sites which accept UGC. It has obviously been moved to the submission page from the main terms of use to attract attention to the clause, in order to increase the chances that Craigslist can rely on it in future.

It will also allow them to argue that subject to compliance with the licence, the information could only have been accessed from CL.

The reality of course is that for a certain number people (perhaps limited) CL will be the only site where the submit content and will therefore not be concerned about granting an exclusive licence.

However, I'm sure a greater percentage of people will not necessarily grasp what Craigslist are asking for here and will not be put off posting elsewhere. Of course, CL will not go around enforcing the terms of the exclusive licence against the user.

The grant of exclusivity will simply allow them to argue that subject to compliance with the licence, the information could only have been accessed from CL, or at least is more likely to have been obtained from CL.

If Craigslist are serious about ensuring they can rely on the exclusive licence it should be made clear that the grant means the user can't post the content anywhere else however this may mean that people would be more put off using the site.

My view is that it's a shame that CL are now attempting to assert an even tighter stranglehold over information originating from users. In the long run it may assist Padmapper in pushing people away from using CL in the first instance.

It's also worth nothing that their terms of use need to be updated to reflect the exclusivity change:

Why did you assume I'm for mandatory quotas?

The only thing I'm saying is that a plenty of people get pushed by society into suboptimal life choices.

Mutiple research from various countries says that girls are as good at math/computer skills as boys, up to the graduation from high schools.
After high school they don't choose science in universities though. Why could that be? If the distribution of talent is exactly the same in high school within boys & girls, I'd expect that they'd pick similar directions at universities.

If they don't, it means that some of them waste their talents.

I don't believe mandatory quotas are the solutions, I'm all against it. But I think we've got a problem, because we could have twice as many great programmers, and great scientists.

An intro to application clustering for High Availability
This is great. The large scrolling format (similar to pinterest) is a good idea as the last thing that was needed was something that looked like reddit or HN. Sites like the Daily Mail have been very successful with this style.

Good luck to the new Digg team!
Exactly.

Their argument was at one stage that they can keep most of the site free by keeping their costs way down by having a simple site. The though free & simple was better than fancier for a price or even that the simplicity was good in itself.

For a long time that argument was interesting and seemed to be working. Now it seems to be not working as well.

It may be that technology & UI brought to the table in 2002 would have been a net loss for Craigslist & that in 2007 improvements would have been too small to bother with. In 2012 there is mounting proof that tech & UI have improved enough that the potential improvements are huge.

When the gap between what a big provider is doing and what is possible gets that big, that's economic pressure. It will be felt in all sorts of ways: competition, users trying to access the data via different interfaces, etc.

Tightening up TCs or setting legal precedents is plugging leaks that happened because of the pressure. Not only does plugging leaks not relieve pressure, it increases it.

But the RPi is an awful HTPC, it's way too underpowered and can only barely cope with 720p decoding. It definitely doesn't cope well with having to do composite overlays like XBMC uses to display controls. The FPS you get in the menus is only also only barely acceptable so even if your content does play the experience is choppy. Yes it's cheap, but it still sucks.
That might technically be true but that clearly isn't the intent here. Craigslist is not going to be suing their users for copy/pasting the same listing across multiple sites...

This is clearly directed to services like Padmapper - which, by the way, I strongly support and wish Craigslist would leave TF alone.
> It must be clear to the user which app each ad is associated with or implemented in.

I was infuriated to be presented with a popup ad offering me (gasp!) the chance to win a free iPad recently. This was using vanilla Opera so I was puzzled about the source. I found out that some apps will inject ads into your browser - I removed the two likely suspects. This has a "chilling effect" when I consider installing new apps since I'm weighing up its usefulness vs. the likelihood that a free app will take similar liberties.
A board that must necessarily select only men may not be composed of the best people available, but a board that happens to consist only of men may, in fact, have the best people available...looking a posteriori at a group's gender composition is not very helpful.
From the previous company I worked at (which used AWS infrastructure exclusively) and many others I've spoken to, IOPS were the leading issue when it came to AWS usage. Many insane solutions were proposed (such as RAID across multiple EBS just to maintain consistent disk performance), but for most use cases the only guaranteed solution was to move everything to RAM and assume disk is either stunted or useless.

My guess is that in the coming weeks, the infrastructure of the companies I spoke to will change substantially. The SSD instances are now the goto solution if you have a server up 24/7 and (Provisioned IOPS / EBS-Optimized instances) are for when you need burst infrastructure with good disk performance.

There are gaps in the AWS armour, but those gaps have been filled in at a consistent rate.
That’s not really a response, is it? User account data could be accessed – because Dropbox was unable to protect your data. That’s not quite as awful a access to user account but it’s still awful.
The traditional wisdom is that carrying a gun for safety doesn't help in such sudden events, as the "bad guys" are generally more prepared, have the initiative, etc.

This is obviously different for instance in a war, where both parties are more-or-less prepared to use a gun at any given time.

Now, I've had military training (somewhat mandatory in my country), and do own a gun. But that is because I find target practice and hunting trips interesting, not because I would find any safety application to owning one.

For instance, I went motorcycling through Caucasus right after the revolution in Georgia. This was a time when gas station attendants carried Kalashnikovs and people customarily brought guns to bar, but still I would have never considered taking any weapons there, as those would have only escalated any problem situation in a bad way. And obviously in the end there were no problems. Nice and hospitable people there, and a beautiful country to visit :-)

This still doesn't compare well to alternatives, pending benchmarks with an actual application if I directly compare it to most other IOPS benchmarks.

So...no? I mean, I don't have to complain about EBS, it's really simple, I just don't use Amazon's stack therefore I have nothing to complain about.

Now if I was somehow stuck on their stack...like from building my product against their proprietary infrastructure...then I'd be stuck on my ass and complaining for an overpriced and underperforming service.

Their recommended solution is to use their proprietary KV store.

I saw this a few days ago - don't remember the source - and moved to click on the HN submission bookmarklet. But then I stopped.

Yes, it's a nice story - very "feel good." Very uplifting. Very encouraging.

But satisfying one's intellectual curiosity?

It's genuinely a great story, but there are hundreds of those out there that I would claim are not in any way appropriate or specific to Hacker News.

And this is one of them.

So to anyone reading this - what do you want HN to be? A place to come for uplifting stories like this? Or a place that's specific to hackers and technical entrepreneurs?

Can it be both? Do you want it to be?

Addendum: I haven't flagged this, because I no longer believe that my preferences and interests are properly and fully aligned with what HN has become. As a result, I don't believe I should flag things unless they're clearly spam.

New from Amazon: Provisioned IOPS for EBS
Glad to have helped.

A variant, less useful for launch (too much to do, not enough time to do it, PR outlets institutionally less motivated by it): let's say you desire coverage by, e.g., a particular blogger. You might try to offer the blogger something. The traditional offer is free or discounted $PRODUCT for them personally or for their readers. This is often less than motivational, because a) it can feel like a bribe, b) your $PRODUCT may not solve a problem for the blogger, and c) the blogger may feel that their writeup of you explicitly feels like hawking $PRODUCT.

Instead of offering $PRODUCT, get deep enough insight into the blogger or their audience to identify a problem that is of mutual interest of you, then create an exclusive incentive about that. The sky's the limit on options, but if someone on the founding team is an expert about something the blogger's audience cares about, then something like "A 30 minute video tutorial about $SUBJECT by $EXPERT" is incredibly motivational. You can use the offer to create something like that as bait for coverage. Highly motivational, totally above board, scales impressively. (The pitch writes itself. "We want to create something of high perceived value exclusive to your readers. Here's an example of us doing it before. Don't worry, no sales pitch included. Interested? Spiffy -- we can have it ready next Tuesday or delay launch until is convenient for your publishing schedule. Can we get a write-up out of this to introduce this to your readers? It might look something like this...")

You can then prepare a landing page for that coverage knowing it will happen, and that landing page should probably have an attractive, mutually beneficial offer leveraging the social proof to the hilt. (I seem to always suggest "Trade something extra for their email address!" so that would be my go-to suggestion.)
Padmapper alone isn't the existential threat. But other well-funded competitors using the same arguments/techniques to offer 'all Craiglist ads, and then more' could be. Hence Craiglist's assertiveness before the principle of reuse is established.
