TI-Nspire / Re: TI-Nspire emulator
« on: November 12, 2014, 05:06:46 pm »
No, the error changes almost every time. It's always "Warning (00003c18): Bad write_word: [...] 00000000" but the [...] could be any of these (and more):
5480040c
6200040c
9940040c
5640040c
53c0040c
9700040c

It doesn't crash with the CX boot1. I don't know if it's loading very slowly or if it's hanging or what because I can't enter the debugger there.

It actually starts, but prints "Warning (00003c18): Bad write_word: 5480040c 00000000" in the debug tab. I'm being very imprecise today :banghead:
It expects a classic boot1 and a classic non-cas rom created with nspire_emu 096 on the PC, right?

I changed it and it runs a bit faster now, compiled for armeabi-v7a.

Sorry, I was talking about this android app. It's emulating a non-cas classic nspire, right?

Is it still supposed to crash in boot1 as you said earlier? Because for me it does.
Still, good job so far!

Site Feedback and Questions / Re: Dear Omnimaga

I'm not overly active here, but what I could notice is that this wouldn't be a place to stay at for a longer time.
Same for me. I don't post often anymore, but I noticed that the atmosphere on Omni is changing for the worse. On the other hand it isn't clear for me that Eeems' behaviour is the cause of it, maybe it's a bit too easy to just blame him? It always seemed like he's the one doing most of the work to keep the forum up and doing a good job there, but yeah that's not what the critique was about.

TI-Nspire / Re: nTxt - Nspire Text Editor

Nice, thanks.

I merged the pull request and removed some of the things with a comment "unused ?". Some others of them aren't really unused, though.

Also, one of my students noticed that there is no key combination for the % character in nTxt. As it symbolizes "modulo" in Python, it is clearly needed, so it should be added to the priority list.
The other characters which aren't possible to input right now are #, $, @. They also may be needed sometimes, so we should choose key combinations to input them. Any suggestions?
Also, could someone host it on a github repo (preferably lkj ?) and could add several contributors so that it'd be easier for anyone to help out :)
I created a github repo at https://github.com/lkjcalc/nTxt.

Nice to hear this is useful to people learning programming in python  :)
The features suggested would be very useful indeed.

Thanks in advance to consider these feature requests... hoping this program is still in development...
I haven't quit developing this, but don't have any time to do programming stuff right now (I just started studying at a university and am very busy... maybe for a whole year too busy to really work on this).  So if you (or anyone else) wants to modify this or add features, just go ahead and do it. It would be nice if you shared your improvements ;)

« on: August 29, 2014, 06:51:55 pm »
I had a similar problem with my HP pavillion once and sent it in. The problem wasn't the notebook itself or the battery but the charger. But I'm not sure how you could find out if it's the same problem in your case without buying a new charger :S

I use VLC because it can play m4a files (the preinstalled player couldn't) and because it's free. But you can't save playlists and it takes two seconds to load every time you go back to the menu, so the other players suggested here are probably better :P

Nice, I was always wondering if it was easy to hack digital cameras :thumbsup:

I can actually tell a story about something like that. My grandpa owns a camcorder (really cheap crap) and I tried to change some settings as the pictures and videos were really awful. So I tried to change the resolution and other properties, which is called "Bildformat" in German.
Now in the main menu there was an option called "Format". I assumed it's the "Bildformat" and clicked on it. And no, it wasn't. SD card empty, photos of a full year lost, without any backups  >:(
Aww that really sucks :( They really should make those options hard to access to avoid these kind of accidents.
Hmmm shouldn't there be a confirmation prompt ? <_<
This happened to me too once, but luckily I was able to restore everything from the formatted SD card using a program to undelete files.

News / Re: WARNING: TI-Nspire OS 3.9 in June?
« on: May 30, 2014, 03:34:31 am »
The OS files are on TI's servers, they just haven't put a link to them on the official Nspire pages yet. It's always like this, they put the new OS up some days (IIRC even weeks with OS 3.6) before officially releasing it.

Ah lol, that would actually have been quite obvious from the results. Good to hear ;)

The starting conditions are wrong (if you're simulating the earth and the sun):
- The initial positions: the real distance is ~150e9, but placing earth at (100e9, 50e9) gives us only a distance of 110e9. I'd choose (0, 0) for the sun and (150e9, 0) for earth.
- The initial speeds: why (3e3, 5e3)? If you choose (150e9, 0) as the starting position of earth, it's about (0, 30e3).

I don't have mathplotlib and numpy installed, so I can't test if it really works with my values. The results seem more reasonable, but I may be wrong :P
