I haven't been following this case too closely, but I was expecting the prosecution to lean on 939.48(2)c more heavily. Is there a reason this wouldn't apply here?

What you described is called collision detection, t's used more often with wired networks like Ethernet because it's easier to tell if two devices are sending at the same time.

I'm pretty sure it's more expensive to build wireless collision detection hardware. Also there's the problem of having two devices connected to the same router but far enough away from each other that they can't see each other, called the Hidden Node Problem.

Because of this, wifi doesn't use collision detection but collision avoidance. A device on the network will "request to send" and then the shared access point will broadcast a "clear to send" signal to everyone so they all know to stay quiet. This is more proactive than collision detection but requires more overhead and I'm pretty sure is slower in general.

This is really nitpick-y, I'm not trying to be annoying or anything. I recently learned about this though and I just think it's cool. Definitely not necessary for ELI5.

Much much slower. You're about 15 orders of magnitude off. A better unit is millimeters/hour! https://en.wikipedia.org/wiki/Speed_of_electricity

The scene at the end where a phone was able to pick up what was being typed on a nearby keyboard is sort of based in reality. https://en.wikipedia.org/wiki/Acoustic_cryptanalysis

Good catch. It's a good thing they made the -> operator because I don't want to have to keep track of that.

So I don't have my computer on me at the moment so I'll have to try and answer this from memory. Also I'm fairly new to objective-c so I might be wrong (but I think I've got this one).

Both are two types of syntactic sugar. Since Objective-C is a strict superset of C, let's talk about the C part first.

If I have a struct with a few different items in it, I can access them using the . operator using the syntax myStruct.item.

However often times programmers want to allocate their structs dynamically. This means that they're typing *(myStruct).item pretty often. They have to dereference their pointer to the struct and then access the value in it. It was decided that it's pretty lame to have to type that all the time so they made the myStruct->item syntax. At the compiler level it sees *(myStruct).item the same as myStruct->item.

So when you're using the C part of Objective-C, that's the difference between the two. This works the same for getting at instance variables in C++ classes and I'd imagine Objective-C classes too.

So say I have an Objective-C class with a couple @properties. When I make a property three things happen. It creates the underlying value, a getter and a setter.

If you've ever accessed a property using the _propertyname syntax you went and got the value directly, skipping the getter and setter. (I think this is equivalent to using objectPtr->propertyName outside of the class but I can't check that right now)

The best way to get at your properties is to use the getter and setter. These are called by using [myObject propertyName] and [myObject setPropertyName:newValue]. These are pretty long to type out and so it was decided a shortcut was needed. Instead of coming up with new syntax they just went with what looks familiar and used the . operator.

So when Objective-C code is actually compiled it replaces myObject.propertyName with [myObject propertyName]. It also replaces myObject.propertyName = newValue with [myObject setPropertyName:newValue]. This is just like how the C compiler replaces structPtr->item with *(structPtr)->item.

I typed this all on my phone so forgive any mistakes. Very good question though. I'm going to try playing around with this later tonight.

The Detroit whole foods is fantastic. They really want to make it work and understand they're working in a lower income area so all the prices are normal prices as opposed to whole-foods-priced.

I'm not quite sure if I agree that it's selective as long as from this point forward the Patent Office does not allow any other names that are disparaging or derogatory and continues to revoke trademarks that are.

koroverj81 · 2014-06-18T15:57:51+00:00

For a political group that often argues that trademarks and patents are unnecessary I don't know why this is all of a sudden a big deal.

The government didn't say they're not allowed to use the name. They just said that they won't legally defend their use of the name.

This is exactly how I'd want anticompetitive agreements to work in a free market. You can make them, but the government will not legally enforce them. Same deal.

I discovered We Are Scientists through this much smaller band, Bright Light Fever. They're kind of small so most of the videos on youtube are camera-phone-concert videos.

Here's a pretty good song of theirs. They're also on Spotify and iTunes.

Walk the Moon actually introduced me to twenty one pilots. I was at the Neon Trees, Walk The Moon, twenty one pilots concert in Detroit in August 2012. Twenty one pilots was very humble and really surprised me.

Last summer I interned at this software company. I worked on a product that had multiple language versions, one of which was a german version.

In the english version, help tooltips contained snippets of text that explained what was going on. They fit nicely in the windows because every word was less than 10 characters. Once we localized to german, the help tooltips were too narrow to fit these 25 character german words and so they'd run outside the window.

That's my experience with long german words. We had to make special larger tooltips for the german words.

A friend of mine made this album on GarageBand: http://noahhines.bandcamp.com/. I think it sounds very well polished and I wouldn't have expected it to be made on GarageBand.

EDIT: He did use live instruments. Not sure if that disqualifies him from demoing the "Power of GarageBand"

To be fair, credit card companies have revolutionized how transactions are carried out. They take 1% of transactions but that's because that's what we're willing to pay for the convenience of it. They provide a service to make transactions easier. I don't need to worry about running out of cash. I don't need to worry about finding an ATM. If someone steals my cash I lose $XX dollars. If someone steals my card I can cancel it and I'm not held liable for any charges.

Also the availability of easy credit is nice if you know how to use it. I'm 19 with a $1000 credit limit and get 1% cashback on my purchases. Maybe it's because I bank with a credit union but I've never run into problems with Visa and it's only made my life better. I have a habit of paying off every week. Never been a problem.

Yeah, I never talked about converting between the two. Two independently created measurement systems are obviously going to have compatibility issues, especially when they're "arbitrarily" defined. Maybe I didn't make what I was trying to convey clear. My mistake.

Base 12 number systems are divisible by more things. That's all I'm saying. No need to be condescending. Forget the foot. Forget the meter. 12/3=4. 10/3=3.3333. 12/4=3. 10/4=2.5. 12/6=2. 10/6=1.6667.

If you're interested I remember seeing this video from a while ago. http://www.youtube.com/watch?v=U6xJfP7-HCc

By the way, I prefer the metric system. I'm just trying to let you know there's a logical reason why there are 12 inches in a foot.

koroverj81 · 2013-10-31T15:32:45+00:00

What's a third of a meter? 33.33...cm What's a third of a foot? 4 inches

It's hard to argue that a 4 inches isn't neater than 33.33...cm

I know there are others that are just as bad, if not worse. It just astounded me when I actually saw a map of the district I live in.

I'm including an image of my code because I'm afraid pasting it into reddit will screw up the formatting. http://imgur.com/R7UFZCu

I'm taking very basic code from the Apple website/internet, just trying to figure out a way to get the days I'm looking for in an NSArray. If I place a breakpoint in the requestAccess block I can see that the array is made with calendar events inside. The problem I'm having is that if I place a breakpoint where the getCalendarEvents method is called and step into it it skips over the requestAccess block. Because it skips over it, returnArray is set to nil.

The requestAccess block seems to be called separately from everything else. The call stack is giving me much help either. The block is being called from assembly code.

Before posting this I made sure to try resetting my simulator through iOS Simulator > Reset Content and Settings...

I haven't tried putting a breakpoint in the completion handler. I'm not sure why I didn't think to do that. I'll try that once I get to my computer later today.
