oh, and i'll add: there's nothing at all wrong with sql, but many folks these days choose to implement their complex data stuff in code and use a much simpler (e.g. nosql) store for the persistence layer. maybe this too could help with operation costs? idk.

If it makes you feel better about AWS - prices are pretty consistently going down.

Ye, I get emails pretty much weekly about price reductions. They are usually only a couple of % but for a big company they probably make quite a difference.

And it gives pretty good confidence that prices aren't going to be jacked up anytime soon.

when amazon starts pimping its cloud offerings with television commercials, we will know we've arrived at the bottom of the market.

I'm usually very much in the "lol IT books" camp, especially for programming since stuff outdates so quickly and yet I just got an order of three paperback books for about 150 Euro total. Two of them are on programming (same language) and one is a "concept book" (related to said language).

Hints:

Spoiler:

Concept book was about 65 Euro, rest was evenly split between the other two

Spoiler:

Concept book has >1k pages

Spoiler:

The programming books are a second and third book for the language i.e. not introductions but rather advanced and superadvanced

Anyone willing to guess? I'll reveal this incredibly interesting info later :P
You can win no price except for a thumbsup.

Code Complete?

Edit: I missed "related to said language" so I assume my guess was wrong.

Stupid question.
MFC C++,
I have a few structs that are used everywhere in my program.
I would like to be able to add a function to the struct that clears/initliatzes all the variables.

Is this possible? I have seen something about adding functions to structs before but when I complied i get errors about the function already being defined. Yes, I could make them classes but I would imagine this would be possible as well especially since they are all just data...

Basically what would be ideal would be

struct MyStruct
{
	bool mybool;
	double mydouble;
	clear();
}

MyStruct::clear()
{
	mybool = false;
	mydouble = 0.0;
}

and then to intilize I would simple do

MyStruct instance;
instance.clear();

I would love to avoid paying out the rear for server costs, but I would need to sit down and figure out if there was a way around it. I need to keep historical stats and a huge player database that is going to be hiding some sensitive info (to the game, not credit card info or anything).

Shouldn't be a problem, just a couple of tweaks to get it compiling:

struct MyStruct
{
    bool mybool;
    double mydouble;
    void clear();  // specify return type (void)
}; // semicolon

void MyStruct::clear()
{
    mybool = false;
    mydouble = 0.0;
}

edit: FYI, there is virtually no difference between structs and classes in C++ anymore. The only difference at all is that struct members are public by default and class members are private by default. So don't worry too much about it!

In c++ you can have functions in structs. I see in your code that you forgot return type, this might be the source of your problem. Try declaring it as

void Clear();

and then

void MyStruct::Clear()
{
}


benholio beat me to it..

You want a constructor. You might also want a clear if you are into recycling.

does anyone use a VPS as their actual computer? apparently its popular with day traders who need uptime 24/7. i coudlnt believe it, immediately security concerns popped into my head

was just wondering if anyone has experience with it

Security is not much of a problem (as long as its setup correctly), for me the bigger issue would be speed.

My guess would be that the day traders have some sort of web based portal setup which they can trade through which will be quite fast, but you try using a remote desktop and however fast your connection is, there is going to be lag.

[_dave_]

yeah i'm sure a lot of "lone wolf" traders use remote desktop vps to a very stable connection in a datacentre, they likely really want the platform to be up and able to close out their positions automatically etc even if your own internet goes down. Can't see lag being much of an issue for day trading, most of them are probably not "scalping" as super-low timescales. like being disconnected while registered for a $5k husng, losing connection with a trade active is most undesirable!

A lot of internet marketers run VPS as main computers too, tho not their only ones. very handy to have multiple / throwaway IPs, and computer(s) that can keep running automation programs 24/7 like xrumer, senuke etc.
