Could not load file or assembly ... The parameter is incorrect

Recently I met the following exception at C# solution:

Error 2 Could not load file or assembly 'Newtonsoft.Json, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b9a188c8922137c6' or one of its dependencies. The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

This does not depend either on my code or on the name of assembly (like Newtonsoft.Json in this case).

When I delete this dll from the solution the compiler tells about another in the same exception. So I suppose something shoud be turned off/on at my PC :)

What causes javac to issue the "uses unchecked or unsafe operations" warning

For example:

javac Foo.java
Note: Foo.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

Runtime vs Compile time

Can anyone please give me a good understanding of whats the difference between run-time and compile-time?

Why does Go compile so quickly?

I've Googled and poked around the Go website, but I can't seem to find an explanation for Go's extraordinary build times. Are they products of the language features (or lack thereof), a highly optimized compiler, or something else? I'm not trying to promote Go; I'm just curious.

Will #if RELEASE work like #if DEBUG does in C#?

In all the examples I've seen of the #if compiler directive, they use "DEBUG". Can I use "RELEASE" in the same way to exclude code that I don't want to run when compiled in debug mode? The code I want to surround with this block sends out a bunch of emails, and I don't want to accidentally send those out when testing.

Writing a compiler in its own language

Intuitively, it would seems that a compiler for language Foo, cannot itself be written in Foo. More specifically, the first compiler for language Foo cannot be written in Foo, but any subsequent compiler could be written for Foo.

But is this actually true? I have some very vague recollection of reading about a language whose first compiler was written in "itself". Is this possible, and if so how?

How are gcc/g++ bootstrapped?

This has been bugging me for a while. How do gcc/g++ compile themselves? I'm guessing that every revision gets compiled with a previously built revision. Is this true? And if it is, does it mean that the oldest g++/gcc versions were written in assembly?

"No newline at end of file" compiler warning

What is the reason for the following warning in some C++ compilers?

No newline at end of file

Why should I have an empty line at the end of a source/header file?

TargetedPatchingOptOut: "Performance critical to inline across NGen image boundaries"?

Been going through some framework classes using reflector and noticed a number of the methods and properties have the following attribute

[TargetedPatchingOptOut("Performance critical to inline across NGen image boundaries")]

I'm pretty sure I have also seen the above comment somewhere else and never followed it up.

Could someone please tell me what this means in the C# and any other context?

How exactly does __attribute__((constructor)) work?

It seems pretty clear that it is supposed to set things up.

1. When exactly does it run?
2. Why are there two parentheses?
3. Is __attribute__ a function? A macro? Syntax?
4. Does this work in C? C++?
5. Does the function it works with need to be static?
6. When does __attribute__((destructor)) run?

Example in Objective C:

__attribute__((constructor))
static void initialize_navigationBarImages() {
  navigationBarImages = [[NSMutableDictionary alloc] init];
}

__attribute__((destructor))
static void destroy_navigationBarImages() {
  [navigationBarImages release];
}

How does the compilation/linking process work?

I've been programming in C++ for a while and I wondered how the compiler and linking process actually works?

Can someone explain please?

What causes java.lang.IncompatibleClassChangeError?

I'm packaging a Java library as a JAR, and it's throwing many java.lang.IncompatibleClassChangeErrors when I try to invoke methods from it. These errors seem to appear at random. What kinds of problems could be causing this error?

Flash CS4 refuses to let go

I have a Flash project, and it has many source files. I have a fairly heavily-used class, call it Jenine. I recently (and, perhaps, callously) relocated Jenine from one namespace to another. I thought we were ready - I thought it was time. The new Jenine was better in every way - she had lost some code bloat, she had decoupled herself from a few vestigial class relationships, and she had finally come home to the namespace that she had always secretly known in her heart was the one she truly belonged to. She was among her own kind.

Unfortunately, Flash would have none of that. Perhaps it had formed an attachment. Perhaps it didn't want Jenine to be decoupled. Either way, it clung to the old, perfect version of Jenine in its memory. It refused to move on. It ignored her (function) calls. It tried to forget her new, public interfaces. Instead, every instance of Jenine that it constructed was always a copy of the old version, down to its classpath:

var jenineInstance:Jenine = new Jenine();
trace( getQualifiedClassName(jenineInstance));
// Should print: com.newnamespace.subspace::Jenine
// Prints: com.oldnamespace.subspace::Jenine
// Ah, young love!

We fought. I'm not proud of some of the things I said or did. In the end, in a towering fit of rage, I deleted all references of Jenine completely. She was utterly, completely erased from the system. My cursor fell upon the "Empty Trash" menu option like the cold lid of a casket.

I don't think Flash ever recovered. To this day it still clings to the memory of Jenine. Her old, imperfect definitions still float through my project like abandoned ghosts. Whenever I force Flash to compile, it still lovingly inserts her into my movie, nestling her definition in amongst the other, living classes, like a small shrine. I wonder if they can see her.

Flash and I don't really talk anymore. I write my code, it compiles it. There's a new girl in town named Summer who looks almost identical to Jenine, as if someone had just copied her source-code wholesale into a new class, but Flash hasn't shown any interest. Most days it just mopes around and writes bad poetry in my comments when it thinks I'm not looking.

I hope no one else has had a similar experience, that this is just a singular, painful ripple in the horrifying dark lagoon that is the Flash code-base. If, by some fluke chance you have, or you have any idea how to erase whatever damn cache the compiler is using, please, please help.

Learning to write a compiler [closed]

Preferred languages: C/C++, Java, and Ruby.

I am looking for some helpful books/tutorials on how to write your own compiler simply for educational purposes. I am most familiar with C/C++, Java, and Ruby, so I prefer resources that involve one of those three, but any good resource is acceptable.

Why does C++ compilation take so long?

Compiling a C++ file takes a very long time when compared to C# and Java. It takes significantly longer to compile a C++ file than it would to run a normal size Python script. I'm currently using VC++ but it's the same with any compiler. Why is this?

The two reasons I could think of were loading header files and running the preprocessor, but that doesn't seem like it should explain why it takes so long.
