Fun with decompiled code.

Graham Bradshaw

I don't get it. Where's the horror?

Yuck.

Goto's used for conditional blocks, mixed in with normal if...then...else blocks.

A SINGLE-PHOTON TURNSTILE, a device in which photons are emitted one at a time under controlled circumstances, has been created by a team of scientists from Stanford (US), Hamamatsu Photonics (Japan), and NTT (Japan). Essentially the researchers use the quantization of electrical conductance to produce a quantization of photon emission. They put together a quantum well (the frontier between two thin semiconductor layers) containing a single electron (other electrons are dissuaded from entering because of a "Coulomb blockade" effect) with a quantum well containing a lone (comparably Coulomb blockaded) hole, and then cycle the voltage across the whole stack of layers in such a way that the lone electron and lone hole meet, mate, and make a lone photon. The resulting device, which operates at mK temperatures, is typically a tiny post some 700 nm tall and with a diameter of 200-1000 nm. (J. Kim et al., Nature, 11 February 1999.)

But it's decompiled code. You can't expect the same structure that a human coder would produce. Humans code for readability and maintainability. Optimising compilers code for performance. Try looking at the assembler output from a C++ compiler sometime. You can't move for JMP, JNE and JNZ instructions...

It's still a horror. ;P

Still don't see why. The compiler's just doing its job - optimising the code for speed or size as appropriate. It's not supposed to be read by humans, so it doesn't matter in the slightest that it doesn't conform to a human's idea of well-structured code.

Sorry Brady, you FAIL. Set Reflector options not to optimize C#. Full of branches/goto's ! In fact you would barely be able to read the non-optimized C# from compilation.

xacc.ide - now with TabsToSpaces support
IronScheme - 1.0 alpha 4a out now (29 May 2008)

So I must apply a setting that makes the output barely readable? ;P

Looks like that might be a good place to test for a SQL injection attack.

Jerry Jeremiah

Not only that. Think of the SQL injection you could do...

Brady Kelly

There is way too much code like that, with direct SQL concats. I am only briefed to add two reports to the system, not secure it. Hell, if I were to decode all the decompiled code and use parametrised queries, I could probably buy a new car with the earnings.
