How to limit setAccessible to only “legitimate” uses?
...e only thing that goes around conventional integrity checks. There's a non-API, core Java class called sun.misc.Unsafe that can do pretty much anything at all it wants to, including accessing memory directly. Native code (JNI) can go around this kind of control as well.
In a sandboxed environment (...

Protect .NET code from reverse engineering?
...ing on the protection, or the amount you spend on a third party protection API/tool.
If you like to implement a solution of your own, using public-key cryptography is a good way (as opposed to symmetric algorithms) to prevent easy hacks. You could for instance digitally sign your license (serial no...

...solution. Instead of using /ZW swicth, windows provides a way to use WinRT API via COM using a wrapper called WRL. It is just that not using /ZW makes coding little difficult since it hides COM implementation details, but it is possible to use WinRT without /ZW.

In Java, what is the best way to determine the size of an object?
...ext object alignment)
Instance size: 72 bytes (reported by Instrumentation API)
Space losses: 2 bytes internal + 4 bytes external = 6 bytes total
You can get a summary view of the deep size of an object instance using GraphLayout.parseInstance(obj).toFootprint(). Of course, some objects in the fo...
Comparison of full text search engine - Lucene, Sphinx, Postgresql, MySQL?
...so I've no idea how easy it is to implement with Django. There is a Python API that comes with the Sphinx source though.
The search service daemon (searchd) is pretty low on memory usage - and you can set limits on how much memory the indexer process uses too.
Scalability is where my knowledge is mo...
How can I determine whether a 2D Point is within a Polygon?
...ticed that macOS UIs are significantly slower than other UIs. After all 3D APIs (OpenGL or Direct3D) also works with floats and modern graphics libraries very often take advantage of GPU acceleration.
Now you said speed is your main concern, okay, let's go for speed. Before you run any sophisticate...
How can you do anything useful without mutable state?
...
@MichaelOsofsky, when interacting with databases and APIs, there is always an 'outside world' which has state to communicate with. In this case, you cannot go 100% functional. It is important to keep this 'unfunctional' code isolated and abstracted away so there is only one ent...

What is an optional value in Swift?
...to nil in Swift — there are no pointers, and no null pointers. But in an API, you often want to be able to indicate either a specific kind of value, or a lack of value — e.g. does my window have a delegate, and if so, who is it? Optionals are Swift's type-safe, memory-safe way to do this.
