Then why do you make a seperate topic, he asked in his own topic .. stop making so many pointless topics, there's a limit.

No you don't understand. Lets even take morality completley out of the picture. I am going to assume you have an aleinware x51 and just for the sake of imagination I will assume you have the best model in the series(which I know you don't have due to PSU wattage). Which has an r9 290x. You would mine next to no bitcoins because ASICs have been made that were designed to render GPU mining obsolete and it has done so quite effectively . You would not be able to buy anything on tiger direct unless you were mining 24-7 which does not sound like something you are willing to do. Plus 24-7 still would hardly get you anything even still. Litecoins on the other hand would give you a profit with the r9 290x however like I said before I am well aware you do not own an r9 290x. If I had to guess you have a GTX 760ti or an r9 270x both of which are bad cryptocurrency miners.
 
     Now lets apply morality to the already bleak picture. What ungrateful person would use the computer their parents bought him to drive their power costs upwards of 80$ a month in order to make less than 60$ a month(both of those figures are rough estimates). So unless you are paying for power, helping pay for power, or giving your profit to your parents than I say you are too young for mining. 
 
     So it is you who does not understand here. If you had a proper hardware configuration I would be all for you mining litecoin but as is all you will be doing is draining your parent's money,

There aren't a lot of examples to show you. Most developers don't write their own engines instead they license them from other developers and once again, there aren't a lot of things already made for Java. In the C, C# and C++ realm you have things like Source, Unity, CryEngine, ID Tech, Unreal, etc. Java is fast enough for pretty much anything, but there aren't a lot of game development related things pre-made and ready to go for a new company. Also, Jagex hasn't dropped Java; The HTML5 version of the game is simply an option, not to mention the fact that the backend is still entirely Java and their in-house scripting language.

I don't even understand why Hotspot Shield is popular. I would strongly recommend Private Internet Access with L2TP/IPSEC. They claim they don't keep any traffic logs or monitor users activities, except they are based in the US - NSA - make of that what you will. Either way any modern VPN deployment shouldn't use PPTP, stick with L2TP/IPSEC regardless of which service you go with. Hotspot Shield provides almost no information as to the type of VPN or encryption provided, it doesn't look like IPSEC. PPTP is strangely pervasive with MSCHAPv2 and very susceptible to offline dictionary attack. It also relies on the users password for the encryption - people don't pick strong passwords. The root of the problem with MSCHAPv2 is it uses DES 3 times...that is additive complexity not multiplicative complexity and is NOT the same as 3DES.

If it's just you and your friends trying to play Minecraft or something, then you don't need to build a proper server. You need to give out more information.  
If you want to host some public gameservers from your house, it's a fairly bad idea due to both reliability and speed of your network, so I'd just rent a cheap VPS/Dedicated server depending on your needs. Unless you're running loads of machines, co-location in a datacenter doesn't make a lot of sense due to the fact that co-location costs are fairly high for a 1u slot and parts get outdated very quickly, so your machine will be incredibly by the time it pays itself off.
 

You can route yourself through some sort of proxy, but I don't see why you would. If someone wants to attack you, then a free/cheap reverse proxy isn't going to mitigate an attack for you and things like CNServers, BlackLotus or Staminus all will run you hundreds per month. If they are truly your friends, then you shouldn't need to worry about it.  

You're not giving out enough info on what you want to do with your server. Some things are OS specific.  
 

Once again, you're not giving out anywhere near enough info on what you actually want to do with your machine.
