Are "65k" and "65KB" the same? Christian From xkcd : 65KB normally means 66560 bytes. 65k means 65000, and says nothing about what it is 65000 of. If someone says 65k bytes, they might means 65KB...but they're mispeaking if so. Some people argue for the use of KiB to mean 66560 bytes, since k means 1000 in the metric system. Everyone ignores them, though. Note: a lowercase b would mean bit, rather than bytes. 8Kb = 1KB. When talking about transmission rates, bits are usually used. Edit: As Joel mentions, hard drive manufacturers often treat the K as meaning 1000. So hard disk space of 65KB

Can someone please disambiguate class attributes and methods for C++? I was under the impression that attribute means any member variable, and method means any member function. Thanks Define "correct". Referring to data members and member functions as "attributes/properties" and "methods", respectively, is common practice - it's the general OO wording. ("attributes" are used in C++ for something else , though, so this may very well be a source of confusion.) The C++ standard, however, does not use these terms (apart from attributes of course, as explained above). If you don't want to risk

Is the C++ term "Container" simply synonymous with the Java term "Collection" ? Yes. Though, if I may speculate here, C++ term container better emphasizes ownership of contained items, as opposed to Java's collection , where there is no explicit memory ownership (due to garbage collection). Items in a C++ container are destroyed when a container is destroyed (hence items are contained or owned), in Java items may continue to exist if a collection itself is garbage collected. Container (wikipedia) Collection (wikipedia) If I understand correctly - usualy this difference is not significant. When

Found here: http://docs.angularjs.org/guide/introduction It states that "You can use Angular to develop both single-page and round-trip apps, but Angular is designed primarily for developing single-page apps. Angular supports browser history, forward and back buttons, and bookmarking in single-page apps." But I'm not finding much on the two terms, spelled exactly that way, but I did find this: http://en.wikipedia.org/wiki/Round-trip_engineering Is this the correct term? Single page app, everything happens on one "page", although the URL might change. Most state changes are shown to the user

In the example below, why do we say "k.send :hello" instead of "k.receive :hello" if, as stated elsewhere , k is actually the receiver? It sounds like k is the sender rather than the receiver. When we say "k.send :hello" who is sending, if not k? (Are you as confused as I am?) class Klass def hello "Hello!" end end k = Klass.new k.send :hello #=> "Hello" k.hello #=> "Hello" Whatever object contains this code is sending the message — presumably main. Let's look at it with more explicit objects and normal message-passing. class Person attr_accessor :first_name, :last_name def initialize(first

Given this: GET /users /users is called endpoint in REST terminology. How do you call the whole GET /users (verb + endpoint) instead? I hope there is one word for it. Thanks. You probably won't like this answer, but here it is anyway: REST does not use the terminology "endpoint" at all. You can check Fielding's thesis yourself: http://www.ics.uci.edu/~fielding/pubs/dissertation/top.htm - open the PDF and search for "endpoint". Fumanchu's answer is probably the closest you get: "/Users" is a relative path and can be used as the Request-URI in the Request-Line as per the 2616 HTTP spec. In a web

I heard that there are 3 kind of concurrency. Deterministic concurrency Message-passing concurrency Shared-state concurrency I know #2 (=actor model) and #3 (=general threading), but not #1. What's that? Deterministic concurrency is a concurrent programming model such that programs written in this model have the following property: for a given set of inputs, the output values of a program are the same for any execution schedule. This means that the outputs of the program depend solely on the inputs of the program. There are ways to ensure this property. One of the ways is the so-called single
