There's a wikipedia article on the subject: http://en.wikipedia.org/wiki/Software_versioningSome intermediate versions are unreleased. Some numbers may also be the build number, automatically incremented by the build server, whether its a release build or not.

I do.
The black screen and clock freeze crashes seem to depend on the state of the calculator (number of files, previous use, ...), this doesn't make debugging easy.

Okay, good. I think it will really be appreciated if we could install Ndless when not near a computer... especially when testing a program that might crash the calculator. We could even spread Ndless around in schools once it is released 
Here is a workaround posted by Yifan on UTI: Ok, just a FYI, if you accidentally restarted the calculator (for 84 keypad or something), and want to use ndless 1.7 again, but don't have access to a computer. If a friend has a nspire, you can use the link cable and install ndless. Same as with PC. Click on Ndless installer, and quickly plug in the cable (other end in friend's nspire). It works.

Here is the latest snapshot by Google cache: http://www.mirari.fr/l5vGThe I/O ports page has been fetched on 9 Sept. The Interrupts page has been fetched on 24 Sept. I don't know if those are the latest version.

I might have an idea for this clock freeze issue: the installation is executed from an IRQ handler, and call several syscalls. The (random) interrupted OS function and the syscalls called by the installer may use TCT_Protect() to protect their critical sections. The TCT_Protect-s may conflict and hang, waiting for the lock to be released, which will never happen.
Maybe connecting the USB cable during the installation triggers interrupts and change the race condition, which tend to bypass the issue.
I've seen the problem on nspire_emu, but it's not easily reproducable.
I'll try to avoid installing Ndless from the IRQ handler, and rather hook a safe OS function.

Sure, this a blocking issue.

Here is what I have understood from the different bug reports: to guarantee no clock freeze and no black screen, the sequence must be to: - run the installer - connect the cable during the installation - keep the cable plugged in during hot reboot Without hot reboot, there shouldn't be any black screen issue, but the freeze issue probably won't be fixed. Perhaps there is some sort of inherent problem in OS 1.7 with booting again without reloading the OS? It does seem to make the OS very unstable, and the "theta" unstability is most probably related. This is why I'm getting rid of it.

I'm currently reworking the installation process to get rid of the hot reboot. This should simultaneously fix "Random black screen after reboot at installation time", "Random crash when running programs on real hardware:", "Variables changed to theta:", "Broken uninstallation:" and "Reboot when turning the calculator on:". But I have unfortunately no clue for this connection requirement

Ndless 1.7 installation now only requires a linking program, so TiLP can be used.
I think several developers such as bwang are testing Ndless 1.7 from Linux.

Excellent, once again brought to us amazingly fast by Goplat

Ncubate does not support Ndless 1.7, which is what qazz42 is using.
Well it should, did you see any problem?

The open issues are identified in the first post of the topic. We are open to any information and contribution to fix them.
And as bwang points out, we would like developers to port their programs to Ndless 1.7 and post any bug report or suggestion. Building from the source code shouldn't be difficult, we can provide help if needed.

I have just tried the 1.7 version, it works quite well Unfortunately the connectors of my calculator are now in a really bad state, I can't keep it in the hand without getting a reboot or a white screen, I must keep it on a table and only press the keys.

remember, this is on 1.7 only, so I really dont mind
on 2.0 there are no reboots So you mean your calculator is unstable on OS 1.7 even without Ndless?
