Got into the windows insider program and a free copy of Windows 10, installed it on my Surface Pro 3 after having to hack an intel driver installer that specifically says not to install it on Windows 10 in the '.inf' file. Works fine though... For now...

That is a preview build, not the final build, so I hope you kept your windows key (or you could be dual booting I guess). Once Windows 10 is released, you will need to change back to your old Windows, and upgrade to windows 10.

All windows 7 and 8 users will be able to upgrade to Windows 10 for free for the first year of its release.

New computer built from parts is up and running!

I'm using an AMD FX 6300 CPU (6 cores). There is an 8-core available for a future upgrade.

I'm using a Saphire Radeon R7 260X GPU. It was listed as a good low-cost option for gaming PCs in a Toms article. (Ah, Phased recommended this GPU in an earlier post.) Upgrading to a 750 Ti can wait for a bit.

Thanks, everyone!

I wouldn't think going from a Radeon 260X to a GeForce 750Ti would be much of an upgrade if any.

http://gpuboss.com/gpus/Radeon-R7-260X-vs-GeForce-GTX-750-Ti

It is not a upgrade, but he was on a really low budget, my suggestion was a 750 TI, and a Radeon 260x if he had to really save money (almost half the price in some cases). Especially when he noted his not a huge gamer, especially not with newer games that get released.

he also said the GTX 750 TI would be a future upgrade, though by the time you decide to upgrade @philfrei , it would probably be better to try going for something more powerful then the 750 TI.

From looking at graphics cards when I was looking one for a friend, a lot of people were suggesting the Radeon 260x over the GTX 750 TI, as it was cheaper and supposedly better in some cases.

Also from my looking around, most people on tomshardware tell people to not use gpuboss as its not a reliable way to compare them.

Better in the long run?

Yes, LWJGL 3 has a bigger plan then just target desktop. And is going to be adding other stuff such Occulus rift support. Also, LWJGL 2 is no longer being maintained, so any bugs will most likely stay in it for ever, while bugs will be fixed in LWJGL 3.

Stable enough, I think it should be, if it was not stable enough, I do not think they would of started to release builds for use.
4  Game Development / Newbie & Debugging Questions / Re: Is LWJGL 3 stable enough for use? on: 2015-01-06 04:31:55
I did a direct copy and paste of a game pretty much from LWJGL 2 to LWJGL 3.

the only error I had (that I remember) from the copy and paste was my Shader loading class, which was horrible in a way, so I changed it.

for changing the display to GLFW, well I pretty much just followed the LWJGL 3 GUIDE, when I did it there was one mistake in it, but I managed to work that out by just checking out the LWJGL3 wiki.

I think if you have a little bit of experience in LWJGL or just OpenGL in general, it should not be really much of a difference.

SHC has also been writing LWJGL3 tutorials on his website, so you could follow his tutorials to learn how set up GLFW.
5  Discussions / General Discussions / Re: System requirements for Oculus Rift? on: 2015-01-04 23:14:13
I believe you really want to go for about 75+ FPS for it to be good.

from their website:

Minimum requirements: A computer running a Windows 7 or higher, Mac OS 10.8 or higher, or Ubuntu 12.04 LTS operating system, 2 USB ports (at least one powered), and a DVI-D or HDMI graphics output.
Recommended specifications: A desktop computer running a dedicated graphics card with DVI-D or HDMI graphics output, with capability of running current generation 3D games at 1080p resolution at 75fps or higher.


I believe at lower then 75 FPS its easier for people to get nausea from the use of it.

from a Reddit Thread, they recommend a minimum of a GTX 770.

The integrated graphics, may be ok for short testing.

I believe Mike has a Occulus rift, I think he integrated it with his game if I remember correctly, may be thinking of someone else, but I think it was him.

That 2.55 million is not pure profit. Only a fraction of that 2.55 million was actually profit.

So now.

firstSubtraction = 2.55 million - cost of development.

now we are getting closer to the profit.

secondSubtraction = firstSubtraction - money to be put into the next game to be developed.

now we have how much profit they actually made. I can't give you values, as I do not know them, and I do not know how much they got paid per developer.

you could even subtract the cost of what it takes to keep their office rent / power bills / internet bills / what ever else is needed to keep their business and office up.

thirdSubtraction = secondSubtraction - business or office costs.

that 2.55 million could actually mean their behind in profit, and lost money because of this game they made.

You can still start your computer.

Find out what pins are the power button on your motherboard, and you should be able to just bridge it with something like a screw driver (something metal) to short it.

seems like there was "another way" to get gems, the auction just got taken down, because of people duplicating gems.
9  Games Center / Featured Games / Re: [Slick2d] Retro-Pixel Castles > Now on Steam! < on: 2014-12-12 06:03:21
bought 50k gems from the market for $1.50, I had $1.57 in my steam wallet Smiley

36k gems left over still, not sure what to get or if I should buy more Tongue

gems are currently going for $0.03 USD (lowest possible amount) for 1000 gems, 50k gems = $1.50
10  Games Center / Featured Games / Re: [Slick2d] Retro-Pixel Castles > Now on Steam! < on: 2014-12-12 05:48:37
you seem to be right.

according the FAQ the bid is the max you want to spend, and steam will automatically increase

Quote
Can I place a "max bid"?
Your bid should be the most you are willing to spend. Steam will automatically increase your bid up to that amount to keep yours the highest bid. Steam will never exceed your bid unless you increase it.

from what it looks like, steam puts it to the next nearest 100 gems

looks like you have a bot bidding on your game, every time I try and get into #1 spot, the bot has put 100 more then me before I even see my name as the highest bidder!

@Catharsis

I chose that motherboard over a full size one, as it was the cheapest motherboard that supports overclocking.

To my research on the G3258, there was really only one motherboard that allowed overclocking, but ASUS released BIOS updates to allow overclocking because of the release of the G3258. I believe the one I chose allows overclocking, and if he overclocked the G3258, he would for sure benefit a lot more.

A lot like to overclock the G3258, so it should be really easy to find a guide to get a stable overclock.

So the motherboard I chose was more to get the maximum power possible. if philfrei will for sure not overclock the CPU (I probably recommend at least looking up guides and deciding if you think you could do it), you could save around $20 and go for a cheaper board, that will most likely not support overclocking.

That would be really easy in a way,

Just have no path finding for the mob. check for collision and it will bump out, and just set a negative velocity.

so it will never know if a wall is in front of it, but if it hits it, it will bounce back.

EDIT: fixed it up, wrote character instead of mob

That should be a lot better, and probably the best you can get for $450 (well, $490, but $45 in rebates).

That motherboard I think lets you overclock, I believe a lot more motherboards got updates to allow for overclocking to use for the G3258, but you may have to update the BIOS to get it to overclock.

if it is to much, you could scale down a little on the GPU, and save a little bit.

EDIT: Oops, looks like I forgot to put a case, you could either reuse your case on your current PC to save some money, or press Edit on the page, and choose a case, you can sort by cheapest to find one. probably be about $500 after rebates, so you may want to scale down on the GPU to something like a Radeon  r7 260x, or down to the GTX 600 series (where you could get a GTX 650 for like $60).
15  Discussions / General Discussions / Re: am thinking of getting this PC, for both gaming and developing on: 2014-12-09 05:44:38
I recommend you use: PC Part Picker

All CPU's can be a minecraft server really, im sure the Intel Pentium G3258 at $60 could probably run one.

the Intel Pentium G3258 dual core CPU may be a good option if you really don't want a good CPU, at around $60 and can be easily overclocked up to about 4.5ghz if you get the motherboard that allows overclocking. People compare it to the Intel i3 or i5 (cant remember which one) when its overclocked and it gives a great fight for its really cheap price.

That 750 TI, I saw one for like $128 on pcpartpicker, and it came with a $15 rebate, so it was even cheaper.

If you want the i3 dual core, I would seriouesly maybe take a look at the G3258 if you want to overclock it to get the best for your money, there should be a lot of tutorial or even videos for overclocking it, just do a little research before you buy it.

I would wait too, saving between $100-$200 USD more, and you could get a way better computer, in pretty much all areas.

an FX 8320 CPU (3.2ghz (or 3.6?) 8 core CPU)
8gb RAM
GTX 750TI (or could go for the r7 260x which would save you around $30 depending on which one you get)
1tb HDD

which would cost around about $600, maybe little more / little less.

but if you are able to I would hold off to get a better computer that will last a bit longer.

Just a note about one line of code that is wrong in the Guide:

at line 41:
1  
glfwSetErrorCallback(errorCallback = errorfunPrint(System.err));


should be:

1  
glfwSetErrorCallback(errorCallback = errorCallbackPrint(System.err));

Learning assembly and C in college right now, I'm absolutely loving it. C really is a portable assembly language, there's very very little syntax sugar which makes it simple and beautiful. I'll be doing much more C now and C++ soon!

I just learnt C++ Tongue and had my final on Wednesday that just past.

We learnt java then C++. going from Java to C++ was kinda big step to begin with, but after you actually start its fairly easy lol, I seem to be able to learn programming languages really fast once I get into a course that we learn a new language.

String print(final String message)
{
   if (debugging)
   {
      System.out.println("GNetServer -> " + message);
   }
   
   return "GNetServer -> " + message;
}

String printERR(final String message)
{
   if (debugging)
   {
      System.err.println("GNetServer -> " + message);
   }
   return "GNetServer -> " + message;
}


now, if the user has debugging mode off, he can still gather the messages as well.

for the 4 line change, it is probably worth it more to satisfy the users in all scenarios.

maybe they want to filter the messaging system, by only displaying messages in the text area that are important to the server host, e.g. someone connected, someone disconnected.
20  Discussions / Miscellaneous Topics / Re: Free or cheap java hosting for my server? on: 2014-10-12 01:38:20
you would buy the OpenVZ VPS from them.

install Putty

Connect via putty

upload your .jar to a webhost

download java onto the vps

create a folder on your VPS

wget your .jar file

run the jar file like you would through a command prompt.


how to connect? they will give you a IP, so you can connect via the IP or you could buy a domain.

also, check out the Github student pack if your a student.

they have a $100 worth of hosting for digitalocean I believe, not sure if you can run java applications on it or if its just a webhost.

123systems.net

I would say its probably the best for the price, iv had days where its been laggy, but for the price I don't think you can really complain.

can be as little as $9 a year.

If you are just going to have a small amount of people on the server and its not commercial product, or really relied upon to work, then I am pretty sure 123systems will probably be enough for you.

I have had 2 years of hosting with it, when the server lags, its usually fixed for sure the next day. and that is mostly hosting a minecraft server when I am not using the server for my use for a friend. they will complain and be like restart the server, its laggy, sometimes restarting it fixes it, or i just tell them it should be fixed tomorrow.

I just found this out last night, I haven't seen anyone post about it on here, so I thought I would share so you don't miss out on it.

https://education.github.com/pack

You just really need to add your edu email address if you have one, and you should get automatically approved.

I believe if you don't have a edu email address, you just have to upload some other kind of proof.

notable things included:
Unreal Engine 4, github micro account (5 private repos), a .me domain, cloud host
(from digitalocean, $100 worth)
24  Discussions / General Discussions / Re: FlipFlop - Examn f(CLK) on: 2014-09-15 04:11:19
we never did questions like this, so I tried to adapt questions that we did to this.

From google searching you are right. its Frequency division. which we never learnt about.

So sorry Longarmx, but I think this full theory could also help Andre Lopes, in the understanding of how JK Flip Flops work.

so the correct answer is actually 3.75 Hz. (which from my little research only works for toggle flip flops I believe? (where a JK flip flop with J and K both are 1 is a toggle) )

and all my replies is on how Toggle works in a JK Flip Flop.
25  Discussions / General Discussions / Re: FlipFlop - Examn f(CLK) on: 2014-09-15 03:52:47
the clock is not required, as the clock only means how often it is executed, in this case it is a falling edge executed, and by the little timing diagram, is it executed straight away.

there for the JK flip flops are currently active.
26  Discussions / General Discussions / Re: FlipFlop - Examn f(CLK) on: 2014-09-15 03:49:55
I believe it would be 5 defined by a high = 5Hz and low = 0hz,

where 60Hz is a high, so it starts high, goes low, goes high, goes low and finishes on the last flip flop as a high.

now work out what the value of a high is.

By what a flip flop does, at J = 1 and K = 1, the value is flipped between high and low.

Also, i just worked out the answer.

the clock is 60 Hz (non required information).

we have 2 possible answers, if we start at a low, we will end with a low, if we start with a high we will end with a high.

No answers are low ( 0 Hz), so it starts as a high, and finished with a high.

at no point does it say what a high is (at least not in english).

One of the standard is like 0 hz and 5hz i think, so, high = 5 Hz, and low = 0Hz.

possible answers are

0hz (starting as a low)

5Hz (starting as a high)
27  Discussions / General Discussions / Re: FlipFlop - Examn f(CLK) on: 2014-09-15 03:41:08
Longarmx: By the answer, you are still wrong though, as the answer is 5Hz (marked by red).

also there is 4 JK flip flops, so the answer would be 7.5Hz (by your definition).

We never really had a question like this, we answered if the output was high or low, or a timing diagram.
28  Discussions / General Discussions / Re: FlipFlop - Examn f(CLK) on: 2014-09-15 03:32:36
like I said it is badly written.

The output should be what the input theres no answer for 60Hz.

so I assume default high in that circuit is 5 Hz. so a high in the circuit is 5, and a low is 0.

on the outputs of each of the JK flip flops will be

JK (1) = low (toggled from a high to output a low)
JK (2) = high (toggled from a low to output a high)
JK (3) = low (toggled from a high to output a low)
JK (4) = high (toggled from a low to output a high)

as the output just toggles between high and low, because when both J and K are high, it makes a toggle.

by the answer, I am assuming high = 5Hz, and low = 0hz.

JK (1) = 0hz
JK (2) = 5hz
JK (3) = 0hz
JK (4) = 5hz

You shouldn't be sitting an exam you know nothing about. circuits can get complicated very fast, especially when you start using flip flops. But if you know the theory behind it, it is a very easy class (at least at my uni).
29  Discussions / General Discussions / Re: FlipFlop - Examn f(CLK) on: 2014-09-15 03:19:23
JK Flip Flops:

if J and K are both 0, then theres no change.
if J = 0 K = 1, its a reset
if J = 1 K = 0, it is a set
if J = 1 and K = 1, it toggles (light a light switch, if its on, then it becomes off, if its off then it becomes on).


so were using toggle always.

its starts at 60 Hz, then it gets ouputted as 0, it goes in the second JK flip flop, and becomes 5 (very badly written question, it makes you assume you know the voltage that is supplied). the third JK flip flop makes it a 0, and the fourth returns it to be ouputted as 5.

therefor the answer to the question is 5 Hz.

How the answer is 5 Hz, well I cant read your exam, so I cant tell if it says what the voltage supplied to all circuits is, or if you got taught to always use a certain voltage.

EDIT: If I had to answer the question as non multiple choice, I would of probably wrote 60 Hz.

bind your block textures before you start your chunk rendering.

once its bound, the texture coordinates you pass in have to be a value between 0 and 1.

coordinate (0, 0), being the top left, and (1, 1) being the bottom right. so you need to find out the coordinates of where each block is on your texture.

chances are you could probably even combine your enemy textures into the same file, even if they are different sizes to your blocks, some extra code for the texture coordinates for mobs (if required), and you could do it all in one texture bind.
