Is this the club one joins for the privilege of paying $100 a year to get some marginal discounts in buying from them?
The details vary a bit between countries but in the UK you pay £7.99 a month or £79 per year in advance. By default it auto-renews but you can turn that off.
For that you get among other things.
Free next day delivery including weekends on most products. Some exclusive products and deals A video on demand service. A music on demand service
For comparison next day delivery without prime costs £5.99 so if you want to use next day delivery more than once in a month it's cheaper to buy prime.
Do the club members get a free "I'm an idiot" t-shirt?
The network doesn't normally care if the packet is TCP or UDP, it just tries it's best to deliver it. Sometimes it cannot be delivered, usually because of congestion but sometimes because of corruption.
The difference between TCP and UDP is that when your UDP packet does get dropped the network stack on the client/server doesn't care, the application data is simply lost. With TCP the network stack will re-send your data and reduce the transmission rate to try to prevent further packet loss (the assumption being that congestion is the most likely cause of packet loss).
Of course this leads to the annoying scenario that protocols that don't play nice can take a disproportionate share of the total bandwidth.
AIUI a monorail can have a relatively narrow track on a relatively narrow set of supports. So you can run it through an existing area without taking up too much space on the ground, being too visually intrusive or blocking out too much light. An elevated rail system tends to involve a much larger amount of structure permanently in the air.
Indeed, the root problem is the lack of seperation between the natural monopoly (or duopoly if you are lucky) of "last mile" communications and the other parts of the buisness (internet service, TV serivice etc). This is compounded by the fact that some of the US providers are extremely large.
IIRC the US forced telcos to allow ISP competition on traditional exchange-based ADSL lines but never extended that to other types of communications service (FTTC, FTTP, cable etc). So as traditional DSL has become a less attractive option ISP competition has fallen off.
Here in the UK they did extend the ISP competition thing to BT Openreach FTTC and FTTP services. They didn't extend it to cable unfortunately but afaict cable is nowhere near as big a thing in the UK as it is in the US (our dominant pay TV provider is sattelite based).
Dumbass mainland Europeans think it's OK to write in English but not follow English numeric conversions resulting in documentation that either makes no sense or worse gives values that are plain wrong.
To me the big question with BFR is who is going to pay for it's development? Will spacex make enough profit on F9/FH launches to pay for BFR? will they be able to convince NASA to fund it despite it directly competing with one of NASAs existing projects?
The potential killer feature of languages like rust is memory safety through compile time proof.
Java and it's ilk offer memory safety though use of a garbage collector such that stale pointers are not possible but garbage collectors come at a cost in terms of predicability and playing nice with the rest of the system. C++ tries to provide memory safety though reference-counted smart pointers, but reference counting comes at a high cost so most C++ coders use raw pointers and "references" some of the time. In simple code that is ok but add in polymorphism, event handlers etc and it becomes difficult to be 100% sure what pointers will be invalidated by any given call.
The big downsides of rust seem to be limited platform support, lack of any ABI stability and the general breakneck pace of development.
What surprised me when I visited Montreal was how many payphones there were. Here in the UK you rarely see more than one at any given location nowadays. In Montreal there were literally rows of the things.
You are wrong BTW. Security and computing power requirements aren't related.
The fundamental problem is if you have two versions of history how do you tell which is the correct version and which is the version manipulated by an attacker without trusting anyone.
The bitcoin solution is to choose the version of history that has more computing power behind it. So more computing power behind the legitimate history means it is harder for an attacker to get a false history accepted.
Only a handful so far. According to wikipedia the launch on October the 11th was the third reused booster. TFA doesn't seem to say if todays launch was a reused booster.
The cost of fuel is a small part of the cost of an orbital rocket launch.
LH2 burns clean and gives the best specific impulse but it's low density leads to high tankage mass and it's low boiling point makes it impractical to manage on long missons. RP1 is easy to handle but it's high carbon content leads to low specific impulse and leads to coking problems.
Methane is essentially a middle ground between the two. Better specific impulse and less coking than kerosene, higher storage temperature and density than hydrogen.
That is because pot hasn't actually been properly legalised, some states have "legalised" it but it's still a violation of federal law and while the feds are currently turning a blind eye they could change their stance on that at any time.
I recall the typical lifespan of a car is about 10 years.
According to http://www.latimes.com/busines... the average age of a car on the US in 2016 was 11.6 years and that number has been creeping upwards over recent decades.
Furthermore most cars are scrapped not because they can't be repaired but because the cost of the repairs are more than the value of the repaired car.
If people really want ICE cars and the government bans new ICE cars then the logical outcome is that the value of used cars will increase and it will become viable to repair cars that would otherwise have been scrapped.
There are a lot of peices to the puzzle of completely replacing fuel powered cars with electric ones. Making the cars cheaper and their range longer is certainly part of it but it's far from the only part.
Figuring out where people who don't live in a house with off street parking or people who are travelling for an extended period can charge their cars is one part. Ensuring the electricity grid can deal with the extra load is another.
Having said that I think you are right that largely gas stations won't turn into electric car charging stations. Firstly the low speed of electric charging requires much more land per vehicle served. Secondly having high current high voltage electric chargers in close proximity to dispensers for flammable liquids just seems like a bad idea from a safety perspective.
Afaict it went beyond mere selective enforcement. They also handed people under DACA work permits and under some circumstances gave them "advance parole" allowing them to leave and return to the US.
Unfortunately our ruling classes have learnt that if you punish people directly using state power you run into all that due process stuff but if you bully private companies into doing it then you can punish people based on mere suspicion.
There are a couple of ideas for trimming the blockchain.
One is "segregated witness", seperating the signatures from the actual ledger. The idea being that while old ledger information needs to be kept forever there is no real reason to keep signatures around forever.
The other is the "lighting network". The idea is that small transactions can take place mostly off-blockchain with the blockchain used as an enforcement mechanism in the case of misbehaving parties and as a mechanism for processing the final net transfer.
How well will these work out in practice? I don't know.
The thing is k-cups are about 60 cents per serving. That is cheaper than popping down the coffee shop. Yes it's expensive compared to bulk coffee but k-cups let you conveniently keep a variety of hot drinks available.
Juicero on the other hand seemed to start at about $6 per serving. That is just way too high.
TVs have always had tuners in them, they were never pure display devices.
In the mid 2000s governments started switching off traditional analog TV in favour of complex compressed digital systems to support more channels and/or free up bandwidth for other uses (TV used a LOT of prime radio spectrum). In the run up to this there was understandably a push to implement digital TV reception in TV sets. That basically meant a computer system with a digital tuner and a MPEG2 decoder. Newer broadcast HDTV standards required H.264 decoding so that got thrown in too a few years later.
So TVs prior to "smart TVs" already had a computer system to drive the digital TV menus, they already had a decoder for H.264. Why not throw on some network ports and a bit of extra ram and add a bunch of functionality for relatively little extra cost.
At least I suspect that was what was going through the minds of the people who built these things.
The problem of course is that the internet is a very different world from the broadcast reception world. Broadcasters are trusted so you don't have to worry too much about security. Broadcasters also accept that any new technology will have to be rolled out slowly and/or in a backwards compatible way to avoid pissing off users too much.
It doesn't seem clear from TFA whether this affects all TVs of a given model or whether it is a relatively rare issue that is being blown out of proportion.
There's also another relatively recent trend that plays into this: the idea that updates are always good and should be applied automatically. It was never the case that this was a safe practice. Updates need to be carefully evaluated before applying them.
The problem is most people don't have the time/inclination/skill to evaluate updates. So the realistic possibilities for most end user devices are either updates get applied automatically or updates never get applied.
The former leads to stuff breaking from time to time, the latter leads to unpatched vulnerabilities, incompatibility with updated versions of online services etc.

In the UK pickups are classed as goods vehicles.

Just got to hope that you are still in a fit state to travel by the time you reach that point.
It's not mandatory for data partitions. Since vista it is mandatory for the partition on which windows lives.
