Thanks for the example code.

Thats also a Douglas Adams quote from HHGTTG.

I find C++ encourages more pointer use by default, which implies all things are in memory at all the time. C on the other hand has this less implicitly, so things such as handles, deferred messages vs straight method call, have less of a.. friction?

Now you can wrap them up in C++, but then making such things hidden I think defeats some of their usage.

A managed runtime should be handle this better, but I don't know of any Java or .NET runtime that is optimised for a small memory foot print, perhaps paging from a larger virtual space[1]. I'd be interested to hear of any really.

[1] I do know there have been versions of Smalltalk that did basically this, but nothing recently that I've heard of.

Hi, Another Game dev here. Firstly, neat article, thanks for writing it.

I'm curious as to the problem you're exploring/solving here?

"Concatenated struct's in single chunk" is a neat trick. The use case seems a bit broken[1], but I'm assuming that it's from the original video, and your c++-ifying it? Or at least trying to find a nicer way to write this style of code?

If you'r going this route, I'd be tempted not to use pointers at all, and just use offsets and accessors.[2]

  * Lack of pointers means you can load in 1 read. (endian needs to be watched, and assumes you can get the entire size elsewhere)
  * You can also shuffle it around in memory should you be doing something fancy. (defragging heaps might be useful if doing a sandbox)
  * Better encapsulation? maybe..

But the basic point I'd like to make is, there is no nice way to write this type of code, because c and c++ gives us no nice[3] way of expressing it.

[1] Verts and Indices are generally uploaded to a GPU then discarded, but this has the counts, which is needed CPU side for draw calls, in the same chunk so would need to be copied before freeing.

[2]

  struct Mesh 
  {
  	int32_t num_indices, 
  		num_verts;

  	// inline to this struct.. 
  	// assumes Vector3 is aligned 4 bytes.
  	// and that Mesh has been alloced to same alignment.
  	//
  	// Vector3 positions[num_verts];
  	// int32_t indices[num_indices];
  	// Vector2 uvs[num_verts];
  
	inline const Vector3* PositionsBegin() const { return reinterpret_cast<const Vector3*>(this + 1); }
  	inline const Vector3* PositionsEnd() const { return PositionsBegin() + num_verts; }
  	inline const int32_t* IndicesBegin() const { return reinterpret_cast<const int32_t*>(PositionsEnd()); }
  	inline const int32_t* IndicesEnd() const { return IndicesBegin() + num_indices; }
  	// etc
  };

[3] Maintainable, fast at runtime, low mental friction to people other than the author, etc

Thank you for the link. I wonder if Tinker Tots is now having a surge of traffic.

Forgive my ignorance, but what does 'LTS' stand for?

Wonderful links. Thankyou.

What was the query? I'd really like to know if it used bullshit correctly?

Sure could/should/must not be used to advertise the tech, but If I had a pocket watson, I'd have no problems with it calling it like it parses it.

Thankyou.

I'm curious.

>9. Latest research proves that Flame is indeed linked to Stuxnet....

Whats the chance that this "Resource 207" is some 3rd party module that more than 1 developer had access to? I concede that placing the same resource in the same resource location in 2 different unrelated applications is a bit of a long shot, but I dont see it as a smoking gun either.

I did really want it to be real, but I now wondering how long till it is. There were enough very clue-y people say "yeah, the physics might actually work". I'm sure it has inspired a lot of people, who will probably now work even harder if they know they can be the first for real.

There is also the possibility of a Joker pushing somebody (possibly multiple to be sure) else onto the grenade, thus saving their life and causing destruction. Which has 2 possible out comes in itself:

1) Joker pushed another Joker or Cooperator. Which might be uncomfortable for a time, but would pass.

2) Joker pushed a Defectors, in which case some Defectors would want some form justice.

I have no numbers to prove this, just my feeling for the archetypes.
