Cygwin needs admin rights? I'm fairly sure it doesn't.
BTW: The topic is miles away.

There is the possibility to provide a prebuilt cygwin environment, but I guess that's very close to a VM or boot2docker.

I dont understand why Nspire is so slow. I do. They have debugging enabled. Makes reverse engineering easier, but everything much slower. It has like 64 mb memory and 100mb space. YET it manages to be slower than other TI calculators  It's just the OS, not the hardware. Win 98 would run fine if it would run at all  Seriously TI if you want people to use AND enjoy the product, dont just focus on security. I have had one and now i use ti 84+ even though nspire is there for me. And i am actually thinking of getting a Prime and get rid of TI forever I think the same, especially because the "focus on security" doesn't seem to work out, does it?

Nah, 3.9 is bloody fast compared to 3.6 and its got a few extra features its pretty enticing! It's even slower than 3.6 concerning booting, opening files, touchpad, text input... At least for me.

You can find some tutorials for linux and other Unixes on hackspire, if you're using Windows, I strongly recommend you to setup a linux VM or dual-boot.
Or download the pre-built ndless SDK for Windows 
There is a recent version of the SDK prebuilt? The SDK had a bug in malloc until two days ago.

Hi and welcome here, Lorenz! (You're not related to Johannes Schlüter, are you? ) Ndless is basically a jailbreak for your Nspire. It overrides a part of the system and allows user-made native code programs to run. Ndless programs are written in either ARM assembly or C. Most people like to use C because assembly is just a lot harder. That's not 100% right. With the SDK you can also compile C++ and other languages supported by the GNU toolchain (If you're curious, you can also try to use llvm). such as Go or Java. You can find some tutorials for linux and other Unixes on hackspire, if you're using Windows, I strongly recommend you to setup a linux VM or dual-boot.

There is a huge process that needs to be followed before TI can release a new OS. They need to test, distribute and make sure that there aren't any big regressions in the new build (bad updates have bricked devices in the past, they don't really want that happening again). Yes, and you can see the (what I believe is) the build number. For 3.9.0.493 it's probably 493, so they did clearly have some work on building and testing...

OS 3.9 does work with nspire_emu just fine.

Oh Vog ninja'd me.
And I didn't know about that. Does it work on OS 3.1 ? I don't want to upgrade because of all the reasons.
Yes, all programs compiled with the new sdk work on 3.1 as well if they don't use any incompatible features explicitly.

I don't run any lua on my calc and I don't use it for school so I prefer to use OS 3.1 since I can debug on-calc pretty fast. I just need to get myself an UART. The "new" SDK has a feature to redirect stdout to the display with nspireio. It shouldn't conflict with other libs trying to access the display  What would be an UART? RS232 serial connection over CMOS levels in this case Also yeah one reason why I stay with OS 3.1 is how even without nLaunchy I still don't need to re-install Ndless every reboot. Saves a bit of time considering the Nspire startup is already long to begin with. OS size is also a factor The 2 MB or somewhat aren't really an issue and startup time is not an issue either. The solution is pretty easy: Just install nLaunch and you can use both.

It's nice that it came out for new users, even though I won't need it since I have an Nlaunchable calc and I'm still running is 3.1 anyway. Same here, I'm mostly still developing for 3.1. Mostly because 3.1 is much faster (especially file transfer in nspire_emu) and also to ensure backwards-compatibility. My calc runs on 3.6 for school reasons ("domain" function mainly)

well i wanted to be able to control that thing without the need of a computer I can only recommend that you read a bit about MCUs, they're really useful for this kind of stuff (MCU = Micro Controller Unit = Mikrocontroller, in case that wasn't clear)

You can also do this digitally, without pots, by using some analog multiplexers and digital pots.
I built a preamp consisting of a TDA7439 and TEA6420, it sounds pretty impressive, although it's not complex in any way.
You could easily combine it with some PT2257 and control the whole thing over I²C with a MCU with the added bonus of remote control and you can also save/restore some settings.

There are already a few projects similiar to this for other languages, mainly .NET and Java based ones: Robocode, AntMe(German).
You have to develop a simple KI and battle against other KIs.
I actually wrote (well, had to, for school) something for Java and I can tell you, it's not easy to make it interesting for the target group.
And it's not much fun if it gets boring.

I tried using this, but after i opened the .tns file and connected my nspire to the computer, it said "downgrade protection disabled" and now the computer doesn't register the calculator is plugged in, even other nspires don't acknowledge the connection Reboot the calc and try again, some attempts may fail.
