Seeing your code work on another computer tells you nothing at all.
To me it would tell: "your code is correct", for starters. It also tells me to look for the problem elsewhere, outside of MY code. External software libraries that are used. Or the hardware it runs on. It won't give you the solution right away, but it does eliminate one possible culprit - your own code - which is normally the prime suspect.
Value can go up, but when the demand totally outstrips supply and it becomes hard to find bitcoin to make one's payment, good chance something else (without this lack of liquidity) steps in and whatever is left of bitcoin loses all value as it's not used any more. This assuming a digital currency will ever become a serious player, of course.
Considering there's some master file where all the movement of all bitcoin and fractions of it are stored, I wonder what's up with these bitcoin. It should be possible to trace these bitcoin: from the people that lost them, the wallet of MtGox can be traced. And then it can be traced whether they're still in that wallet.
And then? If a wallet is lost, the bitcoin is lost forever? No way to re-mine it or anything? Because this would be bad for the future of bitcoin. 7% disappeared with the demise of MtGox. A large number got lost to some UK garbage belt. More will be lost to whatever causes. Over time there may be no bitcoin left!
Wrong mindset. Click-throughs or direct conversions to sale are very bad measures. Nice if it happens, but it shouldn't be the purpose of an ad. How often do you think newspaper ads get clicked on? I think they more often get a coffee mug put on top of them. Yet considering so many ads are bought in news papers, they do seem to be worth the cost.
Same for web ads. It's the impressions that count. It's that people get to see your logo, get to see your product, so that later when they're in the shop they go for the brand that they've seen many ads of, the brand that they know, over some no-name brand. That no-one clicks on them is totally irrelevant.
The only exception is Google's ads - I'm seeing those ads as glorified commercial search results. If I want to buy a product, the ads are what I'm looking at, as that's often companies that are indeed selling the product I'm looking for. If I want general information about that product, I ignore the ads but go for the organic results instead, which tend to be more review sites and the like, which do not sell the product I'm looking for.
How about: certain strains of bees happen to have natural resistance against the neonicotines.
The colonies that lacked this mutation have by now all died off (the exposure is so high that it takes just a few years for this to happen), leaving only those colonies with resistance, and those are now of course expanding rapidly: in part because there is more room, in part because people are helping them grow faster as there is a commercial need for it.
I thought recoil only happens the moment the bullet leaves the barrel, and as such recoil has no effect on accuracy. The more impressive thing is that the drone handles the recoil without breaking apart or being smacked into the ground, instead it handles it quite gracefully.
In many cases, the full circumstances of an event make the difference whether a law has been broken or not.
Were there any license requirements for things like flying the drone, owning the gun, firing a gun from a flying platform? Was that drone allowed to carry any cargo?
Where did it happen exactly? It may make a difference whether it's private land, public land, a gun range, or maybe a nature reserve.
It is not that black and white. So many possible questions may be raised which may determine that an act is legal or illegal.
Example. If you see something happening, it may be legal, it may be not. If you see a house being built, you will probably assume it's legal for those people to build their house there. But maybe it's not. Maybe on that piece of land, nothing is allowed to be built. Maybe they don't own the land. Maybe the building is not up to code. Maybe it's bigger than allowed. So many circumstances where building a house is legal, so many circumstances where building a house is not legal.
Another example. Grabbing a gun and firing it is, afaik, in general legal in the US. However doing so a busy street I suppose not legal. Aiming it at someone and then firing it, is also usually illegal - note the "usually", there may be moments it is legal, and then again it matters whether you're say civilian, military or police.
They probably check what's passing through the upstream filters, and is handled by a spamfilter.
My spam filter catches some 45-50 spams a day. It misses those with attachments (irritating - get 5-10 of those daily) and a few others that are hard to classify as spam (rather legit business related but not my business), but overall doing a decent job. I'm getting a similar number of legit mails a day, a large number of those being stuff like meetup and facebook status messages. So that'd be indeed about half/half for spam vs ham.
However, that 45-50 spam a day is AFTER greylisting, which basically requires every first-time sender (FROM, TO, source IP) to retry 5-30 minutes later. Many spambots just don't. I have this active for years, and when I installed it the amount of caught junk went down from some 300 a day to 30 a day. If this 10-fold difference is still the case, I'd be getting some 450-500 spam a day, or a 90% spam to 10% ham ratio. I'm not about to switch off greylisting to try this out, though:-)
How to measure (and slow down) sending rates of some bulk mailer, who sends e-mail to hosts all over the world?
The source doesn't have to follow the protocol - they just send out as fast as they can. The destinations (plural - probably big big numbers) have no idea what other destinations get from that source. Most of them will see just a few e-mails come in, that's their share. All the spammer has to do is not send everything for Yahoo at the same time, but intersperse it with mails to other destinations and Yahoo doesn't throttle him - or maybe Yahoo does throttle, but that won't stop the spammer from targeting other destinations in the meantime. They probably do that already, simply by having hundreds of outbound smtp sessions running at the same time.
You see how well that works for traditional paper junk mail, where the cost of sending out mailings, even delivered door to door, is easily an order of magnitude higher than the number you suggest.
It's totally non-existent thanks to this cost, right?
You mean - just like human drivers are tested in various conditions, like dry sunny weather, during heavy rain, with ice and snow and at night, just to make sure they perform well under those conditions?
Rear-ending is something that always comes up in/. discussions about driving, especially by US drivers (the site is rather US centric). Everyone and their dog seem to have been in at least one such accident. I have never been in such an accident, nor have I heard of any European friends that had such an accident.
Add to that, statistics show that US drivers have far more accidents, injuries and deaths per distance (per km or per mile, whatever you like to use) than European drivers, especially those from western European countries. This while US streets are wider and straighter; quite some Americans are scared stiff by our narrow, winding roads - we're routinely doing things like driving 80 km/hr (the legal limit) on country roads, and not slowing down for oncoming traffic while the road is so narrow there's not even a line in the middle... because the road simply is plenty wide enough for two cars.
When self-driving cars can negotiate in bad weather conditions (i.e. ice, snow, slush, etc.), that's when I'll buy into your future. There is a reason why Google chose relatively warm, dry areas with typically good weather. Bad weather and poor roads makes things 100x harder for self-driving cars. Not to mention the ability to handle out of ordinary conditions or events. Figure these out, then get back to me about giving up manual driving. Until then, it's a mote point....
Interestingly you don't mention how much harder bad weather conditions make driving for human drivers, as well. There is a reason that many more than usual accidents happen when the weather is bad, when it's snowing, late at night (sleepy drivers - never heard about a robot getting sleepy), or when the roads are bad and human drivers think they know it all and can continue at top speeds.
Of course they start in good weather - that's also how you got your driving lessons. First make sure you can handle the good weather situations, then add bad weather into the mix.
It's old, it's pretty much done for, and preceded by many better protocols (some of which have also been seriously damaged since, like RC5). It starts to sound a bit like kicking a dead horse.
It's not about the technology, it's about the content of the sheets. That usually also needs updates now and then. New products, new (hopefully improved) sales procedures, etc.
It depends what the people in the company have done before.
When Henry Ford started building cars, he started off at what was then pretty much the state of the art. His main achievement is the mass production part. Car production was expensive, so cars were not for the masses, and Ford changed that. He figured out how to build a regular car (state of the art for his day) and turn it into something that's economically viable and cheap enough for the masses.
This company may well be populated with smart brains that have developed and built aircraft before. It can build on existing technology, supersonic flight is well understood. I don't think there are many technological hurdles to build a supersonic airliner (after all, it's been done before: Concorde). The trick is to make supersonic flight fuel-efficient so operating costs can be cut, as that's currently the big hurdle, and one of the main factors that eventually killed Concorde. Can they do that? Well, time will tell. But to say off the bat "they can't build supersonic because they didn't build anything before" is a poor argument, imho.
Economics have changed: the world population has risen a lot since the advent of Concorde and has become a lot richer as well.
More importantly though: technology has changed. Engines have improved - higher efficiency. Aerodynamics has improved - less drag. Materials have improved - less weight.
I wouldn't be surprised if you can build an aircraft now that can operate at similar speeds as Concorde, but at half or less of the cost. So if you can still sell the tickets at the price of Concorde, it may very well be economically viable.
So your corporate training programme itself hasn't been updated as well? It's just weird to think that 10 year old slides are still useful for training. As if time has stood still in other parts of the company as well. Doesn't sound good to me.
You have to manually search for where the toll roads are and think on how avoid them. Drag the marker around sure but will that give you the best alternative? Can't have it avoid them in the first place and have Google come up with a good alternative right away. Same for avoiding - or preferring - ferries. Also no way to set a preference for secondary roads vs motorways.
So OK those options kinda exist, but it's gone from automatic to manual. How's that better?
Another option that Google doesn't have is to search for fastest route vs. shortest route (often got really interesting results, albeit often totally impractical) vs. most economical route (that option is keeping in mind that cars run most efficient at 80-90 km/hr, so roads that let you travel at that speed use less fuel than motorways where you're doing something like 120-130 km/hr - could even set fuel economy for your car at different speeds); by selecting a slower but shorter route on a regular commute I could easily save 30-40% of fuel, and the 1 hr trip took maybe a few minutes longer.
In Netherlands they do the same for bicycles. All directions same time green! Great fun. Suddenly the intersection is full of cyclists (going in all possible directions), seconds later the intersection is clear, and somehow they manage not to hit one another. Also fun to navigate as cyclist. Added bonus: extra green light cycles for the bikes, cutting waiting time, and far fewer cyclists run red lights!
That's exactly how I learned traffic lights work in The Netherlands. Yet pedestrians you don't normally have to worry about, as they do not get a green light even when you're turning left at a green disk shaped light. Basic safety arrangement. Pedestrians get their own time slot.
Interestingly, the very first car route planning software I used had options to select your vehicle type. Pedestrian, bicycle, passenger car, passenger car with trailer, or truck. It would give different results for different vehicles. You could even fine tune your preferences for say motorways over secondary roads, by giving them a preference score. Tell it to avoid toll roads, or to avoid ferry crossings.
None of these options are present in Google Maps.
The application I'm talking about is from an era that it was distributed on floppy disk as no-one had even dial-up at home, and you had to print out the results on your matrix printer to take it with you in the car...
This were two seemingly unrelated events that independently took out two links. You can add links ad infinito but where do you end? Having two links sounds reasonable to me. It's just bad luck that one gets damaged, and the second has an outage before the first can be fixed. Odds of that happening are pretty low. Adding a third link won't make the whole thing that much more reliable as likely they are already at >99%.
