A spin lock is a way to protect a shared resource from being modified by two or more processes simultaneously. The first process that tries to modify the resource "acquires" the lock and continues on its way, doing what it needed to with the resource. Any other processes that subsequently try to acquire the lock get ...

The cast is technically possible. It cannot easily be proven by javac that it is not so in your case and the JLS actually defines this as a valid Java program, so flagging an error would be incorrect. This is because List is an interface. So you could have a subclass of a Date that actually implements List disguised as...

That would be ArrayList and object[] respectively, if you take the weak typing nature of NSMutableArray and NSArray into account. Arrays and lists in C# (at least for .NET 2.0 and above) can also be strongly-typed, so depending on what kind of object you're storing you can specify that type. For example if you only hav...

The way one does this is to start from the symmetry group $\mathrm{SO}(3)$ of rotations in 3-dimensional space, consisting of the $3\times 3$ real, orthogonal matrices with determinant +1. The infinitesimal generators of this group constitute the Lie algebra $\mathfrak{so}(3)$ , which is the set of $3\times 3$ antisym...

The time to merge two sorted lists is definitely not O(m log n). It is O(n+m). The code looks something like this: allocate c with length n+mi = 1j = 1while i < n or j < m if i = n copy rest of b into c break if j = m copy rest of a into c break if a[i] < b[j] copy a[i] into c i=i+1 contin...

Question: All serious full disk encryption schemes I have looked into use a static password for authentication. For example, TrueCrypt supports two-factor authentication with...
The problem is that most multi-factor authentication methods are just that--authentication. They often require some code to verify the validity of the token or information you present. However, with disk encryption your password is the actual encryption key. There is no gatekeeper involved, either your key unencrypts t...

Question: The book on Integral Calculus by Joseph Edwards in its 24th Art. says: Also it is a further help to observe the dimensions of each side. For instance, $x$ and $a$ being ...
The dimensions here are related to what a physicist would think of as units. Suppose that in this example $x$ represents a length, perhaps measured in centimeters. Then $dx$ , which is a small change in $x$ , is also measured in centimeters. In the denominator, $x^2$ has units square centimeters. In order to subtract t...

Your argument is flawed. Kotlin has not been released yet*, and Ceylon just had its first version released, and I'll quote one of the things it is missing from their announcement : reified generics So, excuse me, but what implementation proves it is possible? In fact, I haven't looked much at what Kotlin is promising, ...

Question: I´m currently studying electrostatics and I´m having a hard time understanding why do the number of electric field lines is proportional to the intensity of electric ...
Field lines are just something we use to visualize the direction of the electric field vector. It's a standard convention to draw them so that the density of the lines is proportional to the strength of the field. It's not a fact of nature, it's part of the definition of how you draw the lines. If you have a system wit...

It is a very broad topic, I can only reasonably cover the basics. The mechanisms are not specific to .NET, they apply to any program that runs on Windows. There are two basic ways that the operating system or another program can trigger an event. The first one is as you assume, the underlying mechanism for a button's...

Looks like a job for block modeling. Google for "block modeling" and the first few hits are helpful.

Long story short, this is possible. If you have folder structure inside your bundle's Entity folder, it's simple. You have to name your ORM files using entity namespace part below of Entity namespace and replacing \ with . . So if, for example, you have Project\TestBundle\Entity\Place\Type entity, the ORM file (located...
