31	General Discussion / Computer Usage and Setup Help / Re: Hosting server	on: 31 January, 2013, 14:34:57
I've have been using Ubuntu Server 10.04 LTS for several years now, and I have never had to put the server down because it crashed or something similar. I'd have had an uptime of more than a year and a half if I wouldn't have had to shut it down because of a hardware issue. My server has a static IP, and I use it daily for mail, sharing media, hosting a website and providing several other services. Ubuntu 10.04 has proved to me to be perfect for a server, and I will continue to use it. And I recommend it too. As for server hardware, I recommend you to also use a RAID setup. This doesn't necessarily need to be hardware RAID, but that's always better if you can get it

For those of you who are on OS X and are having trouble building Luna, I found out why it won't build. In the Luna's readme, it states you need gcc >=4.5, but apple's gcc is gcc 4.2. Using MacPorts (or Homebrew, Fink), install gcc 4.7 (run "sudo port install gcc47"). Then open up Luna's Makefile with a text editor and change any instances of "gcc" to "/opt/local/bin/gcc-mp-4.7". Cd to the Luna directory in Terminal, and do make "dist luna", and it builds!

Code: Select All | Copy To Clipboard

CC:=/opt/local/bin/gcc-mp-4.7
CFLAGS:=-W -Wall -m32
LDFLAGS:= -lssl -lz -m32
VPATH := minizip-1.1

OS ?= `uname -s`
ifeq ($(OS),Windows_NT)
  EXEEXT = .exe
else
 CFLAGS := $(CFLAGS) -DUSE_FILE32API
 LDFLAGS:= $(LDFLAGS) -lcrypto
endif

all: luna$(EXEEXT)

luna$(EXEEXT): luna.o zip.o ioapi.o
 /opt/local/bin/gcc-mp-4.7 -o $@ $^ $(LDFLAGS)

dist: clean all
 mkdir -p dist/src
 rm -f *.o
 find . -maxdepth 1 ! -name 'luna$(EXEEXT)' -a ! -name dist -a ! -name . -exec cp -r {} dist/src \;
 cp luna$(EXEEXT) *.dll *.txt dist

clean:
 rm -rf *.o luna$(EXEEXT) dist

Also, link for those who don't want to build themselves:

Thanks for sharing, I'm sure this will help several members

Quote from: chickendude on 20 January, 2013, 12:08:11 Where did you see that it has less memory? On the page it says 128MB flash and 32MB RAM (is that less than a CX?). The CX has 64MiB of RAM.

The best way is to hot patch the OS, add hooks and stuff such as Adriweb mentioned. This is probably more easy too.

Hi bearscup, there isn't such a calculator at the moment. However it shouldn't be too hard to make one^^ Maybe when I got a spare moment I'll make one. I just finished my C.C.N.A. a couple of weeks ago, hope yours goes well too

Calculator Community / Lua Language / Re: Question on TI-Lua programming

on: 31 December, 2012, 14:10:27

Yes, indeed.

When just loading the script, the height and width of it are still 0, because the window is still loading. On your computer the window is already loaded.
The best is to use on.resize to set your width and height, as it will get called as soon as the window has a proper size.

Also, don't use image.copy in on.paint. The window doesn't resize every time you redraw it ^^
Rather do something like this:

Code: Select All | Copy To Clipboard

str = "4\002\000\000t\001\000\000\000\000\000\000h\004\000\000\016\000\001\000\254\251\\159\239\159\239\159\ ... "

function on.construction()
    monImage = image.new(str)
end

function on.resize(width, height)
    h = heighy
    w = width
    px = w/2
    py = h/2
    wim = w/2
    him = h/2
    monImage = image.copy(monImage, wim, him)
end


function on.arrowKey(key)
    if key == "up" then
        wim = 1.1*wim
        him = 1.1*him
    elseif key == "down" then
        wim = 0.9*wim
        him = 0.9*him
    end

    platform.window:invalidate()
end

function on.paint(gc)
    gc:drawImage(monImage, px - wim/2, py - him/2)
end

Well, it's not a beginners mistake, don't worry Wink

I'm not yet going to explain what is happening, but could you add

Code: Select All | Copy To Clipboard

function on.resize(ww, hh)
 w, h = ww, hh
end

See if that helps

I'll explain later ^^

40	Calculator Community / Lua Language / Re: [Lua] math.atan2() problem	on: 29 December, 2012, 14:22:04
Could you test if the parameters you give to atan2 are the same? Maybe some other issue causes certain variables to be different. (such as putting calculation code in your paint function). Also, can you test just a single atan2 statement, no other code? That way we can see if that function really is the issue.

Don't forget that Homer made a BF interpreter in Lua ^^ Anyways, looks fun

42	Calculator Community / Other Calculator Discussion and News / Re: Can someone tell me what this is?	on: 20 December, 2012, 22:15:58
It's the content of the filesystem, used by the OS (Nucleus). It included many things such as language files.

Quote from: DebboR on 14 December, 2012, 21:27:54 Hello, I'm currently developing a cheap breakout board for the TI nSpire series. I am developping this because I don't like to solder directly to my nSpire. This breakout board will be converting the dock connector to a connector with 0.1 inch pitch (normal header size). All 26 pins will be connected to a main connector, with two seperate pin headers for easy connecting of the UART, 3.3V and ground. I'm letting you know this because if I get the breakout board prototypes, I get 10 pieces. Is anyone intersted in buying such a breakout connector? The price will be around €7 or €8 + shipping. I'm not at home ATM, so I will be posting some pics of the digital PCB render tomorrow. DebboR Hi DebboR, I'm interested in getting one Something like this is very handy when debugging. Looking forward to the renders!

Quote from: DJ_O on 12 December, 2012, 21:48:09 If it was on the computer, then how did an emulator of a '80s device manage to be slower on a GHz processor speed machine? Well, it was made in Javascript. But still, it could have been faster. Or I'm just emulating too fast...
