> The biggest issue you aren't considering is that the biggest advantage of a gun is that you just have to have it. Power isn't shooting someone accurately - it's bringing a gun to a knife fight. Having a knife means you have to close to the target to engage - having a gun means I can stand back and project power.

Brandishing isn't something a gun is for, i'm sorry. It's an extraordinarily bad idea to use a gun as a tool for threatening a would-be attacker for both your health, and your legal well-being.[0][1]

> Furthermore, every firearm made in America in the last century has been certified as drop safe.

Single action revolvers have absolutely no safety other than the geometry of their design to prevent accidental discharge and (sometimes) an external safety. Here is the first list of them I found for sale readily on google.[2]

Here's a list of de-certified firearms [3], I'd like you to notice the amount of modern guns de-certified just last year for sale for being deemed unsafe (for these varied reasons[4]). I apologize for the CA-centric data, it was just easiest to find.

Competition shooting pistols often have absolutely no safety devices at all, and plenty are manufactured within the United States.

Many pistols are heirloomed or sold privately, those pistols are not required by law to conform to any safety standards, and can be sold indefinitely. Their high value nature aids the used gun economy, another incentive to have a gun sans modern safeties.[4 :relics and curios/heirloom footnote]

> Poppy cock. Modern firearms don't just go off [0].

Well, here's a blog post with enthusiasts arguing over that.[5] I have a few guns that were left to me by the deceased, but I am by no means an enthusiast.

Here's a blog-post that used wording similar to yours regarding the last century, but he describes drop-safe guns as 'a vast majority' rather than 'every', further explaining about which (modern) guns are never drop-safe.[6]

Now, let me say that I sincerely hope that someone who is going to take the effort to arm their house with a gun will do the homework to figure out a safe firearm to do so with, and with the proper training; but we don't live in that world. People will grab something convenient, just like anything else in life. That means cheap, old, or a knock-off.

The "no drinking water" signs have to do with health requirements for drinking water.

Water for firefighting, for example, has to be isolated from drinking water to prevent any risk of contamination. Due to how it is used, this water may have to be stored for very long periods of time and provides a breeding ground for all kinds of things you wouldn't want in your drinking water (e.g. legionella).

I'm fairly certain most (non-drinking) fountains use something like a semi-closed loop system where the same water just circulates through the fountain and fresh water is only used to replace any water lost to evaporation or spilling. This means the water is easily contaminated and therefore not suitable for drinking.

In some public restrooms (though this seems very rare), even the tap water is labelled as not safe for drinking. In these cases the tap water is likely not sufficiently isolated from the water tank for firefighting and therefore not safe despite coming from drinking water.

I suspect we'll see another class of fantasy comp develop soon for less-interested and more time-poor players where you don't even pick your team, but are given a random team.

If fantasy or daily fantasy is sports betting, then this underclass of fantasy sports would be something akin to a lottery ticket or "scratchie" rather then these head-to-head games. If you ask me to play daily fantasy, I'll say "No time, sorry" and ignore it. But if you give me an app/page with a pre-picked team and moderate financial interest in it doing well, I may watch the game and track stats.

You could send out random teams ("Your team for tonight is x, y and z!") with an adjusted under/over (for stats, totals, etc) and then give people the option to double-or-nothing with a bet, or whatever. "Win a $5 Amazon voucher, or bet 10 tokens now to have a chance at a $50 voucher!"

The sports leagues are actively interested in gambling as something that gives people another incentive to watch games. If you have no-name in your fantasy team, you suddenly care about every time they touch the ball.
No, DMA has been owned by Rockstar since 2001/02. It never got close to unicorn status. It was worth tens of millions, maximum, when it was purchased by Rockstar. Consider that today, all of Take-Two is worth $2.4 billion (and that's basically at a 10 year high on their valuation).

topics like :
- All the different IT services Amazon are offering
- Cloud application platforms like Heroku & Google Appengine
- Openstack for private clouds
- Publishing webservices / plugins /

The Top 3 Archaeological Finds of 2015
"FanDuel, which still isn’t profitable, has now raised $363 million since 2009. The company has a fast-growing revenue stream, though, and made nearly twice as much as rival DraftKings in 2014."

Danger ahead. If payouts are even a little subsidized by investment/marketing dollars, into slightly-positive-expectation territory, this sort of business can achieve almost arbitrary revenue growth. (Plenty of smart money, or even just intuitive-do-whatever-works-until-it-stops-working money, will be happy to buy $10 bills for $9.50, over-and-over. Lazy susan revenues.)

But when the promo subsidies end, or the happy-to-lose-for-a-while fish who are attracted by mass advertising reach 'extinction', the bulk revenue can disappear just as quickly.

Will this remain a favored form of negative-expectation gambling afterwards? Maybe, but probably at a size way below its novelty/subsidy-goosed peak.... which might already be behind us.

Airlines work well in a sense because there are relatively few carries. Other industries are as streamlined or heavily regulated to make a Kayak for x work as well. Like Kayak for rental housing would be great in some cities but trying to coalesce property managers is worse than herding cats.

It's just too hard to get the information to aggregate. Job boards the same way. Plus lots of competition and it's such a local-market driven thing.
Haha, that's hilarious. Teacher: "Write a report on the story of Icarus. What lessons can we learn?" Then you write up a report like a post-mortem of a failed rocket launch. Materials science, testing, dry runs, abort procedure. A graph of wax temperature versus sheer strength, tensile strength. Altitude versus temperature graph. Temperature versus phase diagram for wax. Finally conclude that besides lack of a suitable abort procedure the major error was in choosing a midday launch, dusk should have been chosen in order to reduce incident light, which would have kept the temperature within design constraints for the altitudes Icarus was flying. Until more suitable materials were found, the Greeks should stick to night-time launches.
The technology ratchet
The claim of BadBIOS was that it was supposed to infect new devices through the audio channel.

While Hanspach et al demonstrate the data transmission vector, it's no infection vector.

For that, you'd need to be able to exploit the HD Audio codec (or whatever chip gets to interpret the signal) - and there are dozens of models by different vendors out there. That's a very different claim.

> move this memory around

A lot of people seem to assume that Chris (the author) was talking about managed memory, which he never mentioned once. Managed memory is runtime safety, a type system is compile-time safety. He's complaining about the type system. As an example:

> address memory as a flat range of bytes [...] I can then typecast into byte-aligned structs

You should never have to do that. You shouldn't be able to do that. Your job should be far simpler. Look at unique_ptr: a whole class of bugs are eliminated by this ZERO cost abstraction. Possibly what Chris is advocating is being able to describe what an I/O port is to the compiler and then using that abstraction to write your SCSI driver. This intent should be compiled down to as-good machine code (if not better) than what your C compiler would have given you - in the same way that unique_ptr is compiled.

I don't think any existing language gets this right.
This is something that Safari on OS X gets so right, that I've long been amazed (and annoyed when I have to use other browsers) that the other browsers don't copy the functionality.

In Safari, if you tab out a new page, it will load the content but pause it until you show the page. So you can tab out a bunch of video pages and they each only autoplay when you tab through them.

Wanting the same functionality on Chrome seemed to involve plugins or clicking (which has now turned into right clicking and choosing play).
There's a fourth option: disallowing freeing. A resource, once allocated, cannot be repurposed. It sounds crazy for those of us who grew up with the resource limitations of the 1980s, but as time passes it becomes an increasingly interesting idea.
The players who care more about the fees are the better players who see it as cutting directly into their ROI. If only top players move to low-fee sites, that doesn't help their ROI much, does it? Casual sports betters prefer sites with convoluted bonus and rakeback programs to sites with low fees. I think casual DFS players will stick to the names that are on the commercials and the sites with the prettiest and most trustworthy-looking UI. I believe something similar happened in poker, where players would go to the sites where the worst players were, and not where, player-strength being equal, they would make the most money.
It never gets any easier!

Not true if you use a decent framework.
I was asked whether we had guidelines for speakers for the events we run as they would be great tips for someone that wanted to improve their public speaking skills.

Not sure this is an exhaustive list but it seems to cover most of the things that the best conference speakers have in common. Would welcome other contributions.

Written from perspective of audience but many of those things make a conference organiser's life easier too and both of those things dramatically increase the likelihood that speakers will get asked back.

Right now is more or less the worst possible time to plan out a new space telescope. There's one simple practical reason, the JWST hasn't been launched yet. Once it has then that'll end it's budget dominance and if it succeeds then it'll hopefully start to pump some fresh air back into the space science community, after having sucked most of it up for the past decade with its cost-overruns and schedule slips.

But far more important than that are the drastic changes coming to space launch. Reusability is on the horizon, and innovative launch concepts are being tested. Almost assuredly launch capabilities and launch prices 10 years from now will be very different. And that is the primary driver of cost and program complexity when it comes to orbital space telescopes. High launch costs means that spacecraft need to eek out the utmost performance from within tight payload margins, that raises cost. It means there's no room for contingencies like backup missions, which raises the stakes. And because the cost and stakes are so high that means the vehicle has to be over-engineered so that it has a very high probability of completing its primary mission, which further increases cost. Even though launch doesn't end up being the majority of mission cost, it still has an enormous impact on it.

In a decade or so it may be possible to launch payloads at somewhere between half to 1/10th of current costs. Which opens up a whole new vista of opportunities and changes the local cost/benefit maxima sharply. It will likely be possible to build, launch, and operate a Hubble-class telescope for less than a billion dollars, perhaps only a few hundred million dollars. That makes it more feasible to test innovative designs, it makes it easier to launch a fleet of similar or identical telescopes to increase science throughput, and it makes it feasible to simply replace failed telescopes. That may very well change the way we design and build spacecraft, relying more on extra mass instead of bleeding-edge over-engineering to provide longevity and reliability. But it'll also provide new insights into orbital telescope design, instrumentation, as well as abundant new science data, all of which will inform next generation telescope design, likely leading in different directions from the designs and budgets we would choose today.
I'm willing to bet that those would be considered very basic and obvious problems to the people developing these cars. They work on this stuff every hour of every day.

The AI will know (and share with other cars) tendencies for individual intersections and eventually share broader traffic knowledge. There will come a time where we just cannot compete with that. They will know every intersection's peculiarities and we'll know only those that we frequent, at best. They'll adjust for weather conditions too where we'll go by gut feel - e.g., at intersection X, what did people tend to do in light rain, driving West in the morning. What about on a hot day going N-S in peak hour. They will have data at hand for every location, condition and time if need be.

You're not selling to people who buy things with money.

Looking at your list, they seem to be handy things that consumers could use to solve a problem that bothers them a little. What you want is a product that fixes the immediate existential threat that an otherwise wildly successful company just discovered they have (ideally as a result of reading the copy on your homepage.)

I made a list of things my next SaaS product should have. No particular order, but give yourself a point for each one you can tick:

- Business: Purchased by businesses as opposed to consumers

- Aspirin: More like aspirin (takes an existing pain away) than a vitamin (nice to have)

- Valuable: Immediately saves >$100/month by using it

- 50x500: Market to quickly sell 500 subscriptions at $50/month

- Paid: Paid from day one as opposed to Freemium

- Recurring: Continues providing value every month, not just one time or occasionally

- Immediate: Useful straight away by user #1

- Network: More useful the more users in the Org use it

- Supportable: Low instance of customer support. Few emails asking for help

- Fun: Interesting enough to keep working on

- Buildable: Not to huge in scope. Can be built as MVP, then iterated

List out your ideas, add up the number of boxes they tick, and that's your score. I've had a lot of ideas for a lot of things I wanted to build, but thus far none that score more than 10.

My existing products get a 6 and 7 respectively, and they still bring in enough to live comfortably, so it's certainly possible to succeed without all those bits above. But if you can meet most of those requirements, you'll find yourself on a much easier road.

Good luck!
I'm building a multi page app that has a single page which is extremely complex (it's an image based marketing tool, the complex page is the visual editor) and I'm finding browser extremely finicky in their memory management.

I don't know how making a real single page app could be possible for overly complex applications. More than once I managed to crash the chrome javascript engine in a way that could not be recovered even when reloading the page and nothing short of a task manager kill could restore functionality

we are probably abusing too much canvas (we use fabric.js for image maniulation), but adding and removing the canvas from the dom should be safe enough, as we make sure not to store anything outside the dom itself specifically to avoid leaking resources

everything in memory is attached to data entries or in event handlers and browsers should be able to clean up them when the nodes are removed, except they dont.

Mozilla seems to take anywhere from 1 to 3 months to fix these severe bugs. Adobe takes days.

Source for this complete and utter FUD? Certainly not the links you gave:

Jan 13, 2015: Firefox 35.0 shipped with patch

It's hard to get dates out of the others because the bugs are still hidden, but the "fixed in" is often a security fix update after a release, which means it can't possibly have been > 6 weeks.
