Ok, I've managed to get yacas installed and working on my Samsung Captivate. here are the steps I used:

downloaded the my.tar.zip (it has everything already pre-compiled, thanks XVilka!)

Unzip it and copy the bin folder to an SD card.

for my Captivate, the filepath to get to my sd card may be different from yours, so be sure to check! Anyways, I used the Android SDK adb shell to get terminal access to my phone, but a terminal app on the phone itself works as well (I used adb because my laptop keyboard is quicker)

cp /sdcard/sd/bin/omap3430/yacas /system/usr/bin
chown root /system/bin/yacas
chmod 755 /system/bin/yacas
cp -r /sdcard/sd/bin/omap3430/scripts/* /system/usr/local/etc/yacas
yacas --rootdir /system/usr/local/etc/yacas

And then it should be installed properly.

So now that I have it installed and working, I need to get a feel for the syntax it uses to parse commands, get a list of commands, and start sketching out a UI for it.

Thanks for posting how to get it running on the Galaxy S.

But what about using X over SSH to run software remotely with a GUI such as Matlab? I use Matlab all the time, and loved being able to do this on the Nokia N900.
[Android Q&A, Help & Troubleshooting] asrrin29:
I don't see why you couldn't do that, however I'm a bit old fashioned and like having an offline program rather than a remote application. Plus, if I understand you correctly, running a remote version of Matlab or other similar software would not work well with the resolution available on even the enormous 4.3 inch screen of an Evo. But I'm not an expert with linux, so please correct me if I am wrong.
[Android Q&A, Help & Troubleshooting] Dr.Strangelove:
Is somebody still working on this?

I would really appreciate it to see a CAS App for android! Still cant understand why the devs of Space Time (iPhone) do not port their software to android...

An other cool App would be an UI that can connect to a Mathematica remote kernel...
[Android Q&A, Help & Troubleshooting] sgmanohar:
Matlab is not a computer algebra system!

try doing d/dx(x^2) = 2x in matlab
[Android Q&A, Help & Troubleshooting] XVilka:
I can code C-backend, but there no ppl, who want write GUI to it.

EDIT: hm found this project http://sourceforge.net/projects/yacasandroid/
[Android Q&A, Help & Troubleshooting] xdarkfirex:
This looks like it could be great. I know how to make gui's but my android development skills are raw. Yacas seems to be something you would use NDK for since you don't want to require root access. And a java implementation would not be ideal if you want speed.

http://apcmag.com/microsoft-no-windows-phone-7-upgrade-for-windows-mobile-6x-devices.htm

Owners of HTC’s highly-praised HD2 touchscreen smartphone will be unable to upgrade the device to Microsoft’s new Windows Phone 7 software when the OS is released towards the end of the year.

Despite the HD2 meeting many of the criteria laid down in Microsoft’s ‘Chassis 1’ spec – including a 1GHz Qualcomm processor, high-res capacitive touch display, 5 megapixel camera and 3.5mm headphone jack – the phone will be ruled out for the simple reason that it has five buttons instead of the three mandated for all Windows Phone 7 devices.

That’s the official line from Microsoft, at any rate. Natasha Kwan, General Manager for Microsoft’s Mobile Communications Business in the Asia-Pacific region, told APC that the HD2 “doesn’t qualify because it doesn’t have the three buttons”.

At least officially, but un-officially I would bet that some gurus from XDA-dev will make it happen ... when the WP7S is available end of this year. They should be able to get the ROM and port it to HD2. That's my feeling.

And there is still hope this will be negated on the next MIX10 .... Microsoft will say "That's not true, HD2 is upgradeable to WP7S and here is the beta ROM you can put and test" :D
[Windows Phone 7 Development and Hacking] young blade:
This .. its just... don't have words 4 this..:mad:

Now its all up to the devs..
[Windows Phone 7 Development and Hacking] killavirus:
That well and truly Sux ....

But i have very little to worry about

We're at XDA's !!!!!!!!
[Windows Phone 7 Development and Hacking] Shasarak:
Well, as has been pointed out in many other threads, producing a cooked ROM based on a new CE kernel is a completely different proposition from porting between different versions of WM5 and 6. Whether we see a cooked HD2 ROM based on WP7 is pretty much entirely dependent on three things:

1) There needs to be a beta WP7 ROM for the HD2 produced by Microsoft and/or HTC. (Evidence that this exists is strong, but not absolutely conclusive).

2) The beta version has to be recent enough that there is no change to the driver architecture between it and the released version.

3) The beta has to be leaked.

IMO, the last of those is not by any means guaranteed this time round.
[Windows Phone 7 Development and Hacking] Ruudfood:
I hardly think that because the HD2 has 2 extra buttons this would prevent WP7S from running on it! Seriously, who are they trying to kid?
[Windows Phone 7 Development and Hacking] Shasarak:
Hmm, there's some more stuff in the linked article that the original poster doesn't quote:

Assuming that it's not just a matter of buttons, I'd say that makes even an unofficial HD2 port a bit less likely, but we'll see.
[Windows Phone 7 Development and Hacking] gogol:
Completely understood.

We could wait that ROM anyway, whether leaked or come from official WP7S phone later this year or God knows where.

There are many amazing things which were unthinkable done by XDA devs here. They just too many to mention here ... HTC Kaiser missing drivers, WM6.5 on <insert HTC devices>, Android on WM, etc.

Even if it could not be done, but having HOPE is not a bad thing ...

However, certainly, this could potentially put a halt on HD2 sales.
[Windows Phone 7 Development and Hacking] Shasarak:
It could certainly be enough to prevent an official WP7 upgrade for the HD2, and we now have word from an actual Microsoft representative which suggeststhat this is indeed the case.

That reminds me, where's Freyberry? He owes a number of people a grovelling apology for insulting them when they suggested that the buttons on the HD2 might have an impact on WP7 availability....

Having hope is a bad thing if anyone buys an HD2 because of that hope, only to have it proven unrealistic.

A ROM from an official WP7S phone almost certainly wouldn't be adequate. Unless every single hardware component in it is identical to the HD2, you would still have no way of getting hold of the necessary drivers. So if, say, the camera in this phone wasn't the same as the one in the HD2, then it would be impossible to make a cooked WP7 HD2 ROM from it in which the camera works. The only way you could do it is if there is a group of official WP7S phones which between them contain every single component in the HD2 - not just the chipset but the camera, proximity sensor, touchscreen, everything.
[Windows Phone 7 Development and Hacking] wmh:
I bet the "5 buttons" reason is a bad excuse to not having to reveal more info prior to MIX.

My guess that this reason is BS because of the announcement of LG's first WP7 phone, this is taken from the article about it on neowin:

source:

http://www.neowin.net/news/microsoft-reveals-first-windows-phone-7-series-handset-from-lg

Obviously this phone has more buttons than the HD2 and will be running WP7.
[Windows Phone 7 Development and Hacking] gogol:
No comment on this he he he :)

You are correct, but I also said:

However, certainly, this could potentially put a halt on HD2 sales.

What I mean with hope is for "current owner" of HD2

Fully understand. But do you think all the hardware components would be exactly different?

Learning from past experience, most if not all past devices still have the same hardware components. That's why XDA can still port WM6.5 to some of old devices.

Why would suddenly the hardware is now totally differents?

Even if it is new hardware component, I would think it will be backward compatible with the old hardware.

Well, it could be that the new OS requires to use "new drivers format" for that "old hardware" (HD2) ...

That is quite obvious.

So, either the new WP7S devices are still using most the same hardware components, which means the WP7S drivers will be somehow backward compatible with old hardware.

Or, some super clever XDA dev will create new drivers for HD2 using new device driver format of WP7S. This sounds impossible, but .... who knows?
[Windows Phone 7 Development and Hacking] GuestK00306:
I won't believe any article until MIX. Especially an article which doesn't mention the HD2 in the quote ;)

I see the words "current phones" and "HD", but no HD2 in there. But hey, I'm clutching at straws now really!

New kernel, relatively new architecture will mean that it will be effectively like porting HD2 to Android...only with zero documentation.
[Windows Phone 7 Development and Hacking] caliban2:
reverse-engineering drivers? :D just look at the problems present in android-development... ^^ the problem is you need exact (!) specifications of the hardware to start with - and that's closed-source. even after that it's not easy.

but even IF some magician would pull this off, i have learned one thing with the x1: not having an official firmware adapted to the OS you want to use deprives you of a stable base, it will always be patchwork at best. (and i'm talking 6.1 -> 6.5 here, where the difference isn't that big)
[Windows Phone 7 Development and Hacking] domineus:
I was going to buy a touch hd2 for 425 off craigslist with the complete idea that this phone would be wp7s. Seeing that it won't has left me stay with my reliable tp2...

its a shame actually I wanted the hd2 to be wp7s for obvious reasons
[Windows Phone 7 Development and Hacking] chris5932:
If this is true I will sell my hd2 soon!

I mean the buttons... its nothing but a lie, its not the true reason!

They could have told more early that the HD2 wont get an upgrade they just didnt because they want to sell it!

Then the "russian twitter" thing was only marketing to sell a phone with dead OS..

But I still don't realy believe this.. windows phone@twitter told that "there 'may' be information next month".. well it is " next month" but the hd2 wasnt mentioned directly as far as I can see..

Cheers
[Windows Phone 7 Development and Hacking] vangrieg:
If the buttons are the culprit, I bet the problem isn't the extra buttons, but lack of the Search button. Sure the Home one could be remapped, but what about consistency, ease of use for consumers etc.?
[Windows Phone 7 Development and Hacking] MasterTP:
Agreed, it looks like nothing is set in stone yet:

http://www.mobiletechworld.com/2010...-because-of-hardware-buttons-dont-be-so-sure/
[Windows Phone 7 Development and Hacking] Shasarak:
That would be a good reason for HTC not to offer the upgrade, but I don't see how Microsoft sells more WP7 licences by not allowing the HD2 to be upgraded. From Microsoft's perspective what matters is getting an absolutely consistent look-and-feel across all WP7 phones. So I find it plausible that Microsoft might refuse to sell HTC any licences to install WP7 on HD2's, given the lack of a search button.
[Windows Phone 7 Development and Hacking] RustyGrom:
I'm not giving up hope yet though. They've already announced the button requirement. If the HD2 was going to be disqualified for this reason why not say so? I don't think this is over. She's all the way on the other side of the planet from Redmond and most likely less 'in the know' just for this reason. Just this Saturday a much more knowledgeable MS rep said 'Wait for MIX' in regards to the HD2 getting an upgrade.

The statement leads me to believe that the MS rep in a far flung region is just interpreting the 3 button requirement to automatically mean that MS won't allow any current devices to get the upgrade and not them having actual info that the HD2 will specifically not get the upgrade. That and MS will need to get some sort of hardware in devs hands before official availability. An emulator is nice and all but real hardware is key. The HD2 is supposedly launching here in the States right after MIX. Coincidence? Maybe I'm just grasping at straws but fingers crossed nonetheless.

I think you're making some assumptions that aren't fair to make at this point in time. If the hardware is nearly identical to the HD2 (which it will be) why would it need an entirely new bootloader as compared to other WP7 devices? #2 (and therefore 3 as well) doesn't even make sense as they're developing this on CE. It's not like they're going to change CE versions mid-dev. The driver architecture won't change. MS has stated that they're doing all the driver dev, not the OEMs. As long as the HD2 matches the chassis specs, there's no reason it will need different drivers. The only thing that concerns me is the bootloader as it's my understanding that it's unique per device and likely a WM6 bootloader won't be able to boot WP7.
[Windows Phone 7 Development and Hacking] chris5932:
Well I agree with most ppl here.. lets just wait til MIX..

There are severall things said that fight each other!

MS:"info for hd2 may next month","no upgrade for WinM 6.X phones"

HTC:"HD2 is able to run WP7's",

HTC twitter:"HD2 will get an upgrade" ..

I think the chances are still as before the article but make ur own guess.

Cheers
[Windows Phone 7 Development and Hacking] Ganondolf:
I wonder if microsoft is using some sort of qualcomm system on chip like there new MSM7x30 soc. As microsoft is only letting snapdragon devices, im sure they have a certain gpu that they have to use so the performance is the same on all handsets. so a SOC would make sense and that might be why the hd2 does not meet the specs.

Also i dont think the hd2 has 4 point multi touch.

Also i think microsoft wont let them upgrade as they wont 3 buttons only on the front so to let the hd2 have a upgrade on to wm7 makes a mockery of wm7 requirements.
[Windows Phone 7 Development and Hacking] young blade:
What date was MIX again? 10 or 15 march?:confused:
[Windows Phone 7 Development and Hacking] vangrieg:
For whatever reason - this may be a subject of very complex negotiations, you'll never know what kind of bargaining chips they may or may not use. :)
[Windows Phone 7 Development and Hacking] OndraSter:
15 - 17 march
[Windows Phone 7 Development and Hacking] domineus:
microsoft is teasing us well I must say
[Windows Phone 7 Development and Hacking] freyberry:
Lies, all lies... don't believe the bull**** MS tells you. The button thing is not the issue. It's all politics... and they won't ever tell you the real reasons.
[Windows Phone 7 Development and Hacking] RustyGrom:
It's clearly not a technical reason and they haven't claimed that it is. It's a uniformity decision that they may or may not be holding firm to.
[Windows Phone 7 Development and Hacking] domineus:
granted

but the lg phone with wp7 looks nothing like the wp prototype device

in fact I thought the lg was quite ugly! but at the same time its very tough to say I mean there is a large demand for snapdragon phones to receive the upgrade so we should wait till mix
[Windows Phone 7 Development and Hacking] freyberry:
I was talking about the button story. It's a lie.

Plus, there's no technical reasons at all, cause WP7 already runs on the HD2.

Don't believe their lies.
[Windows Phone 7 Development and Hacking] burnblue:
Yeah, this is pretty much the right answer. They set rules, and they have little incentive to break those rules for what will be a near year-old phone.
[Windows Phone 7 Development and Hacking] freyberry:
Don't let them get away with the lie about the buttons!
[Windows Phone 7 Development and Hacking] elyl:
What's the politics you speak of?
[Windows Phone 7 Development and Hacking] young blade:
Lets face it...

WM7 would be so HOT looking on the HD2...

If there won't be an update.. I believe HTC is getting ready to release an HD3 at the end of this year.. and how different will the hardware be?? I think pretty much the same so it wont be that hard for devs to start doing what they do best..:cool:
[Windows Phone 7 Development and Hacking] RustyGrom:
How is it a lie? They've said they're requiring 3 buttons and described those buttons. They can simply choose to allow the HD2 to break those rules or not. No need to lie at all and they haven't. Nowhere did that quote or any other quote that this is a technical decision. Besides, this is hardly an official announcement.

And if WP7 already runs on the HD2, prove it.
[Windows Phone 7 Development and Hacking] freyberry:
I don't have to prove anything. If you want to believe Microsoft's stupid lies... your own fault.

Anyway, no matter if you belive the crap they're telling you or not, it won't change anything. You'll never get to know the real reasons.
[Windows Phone 7 Development and Hacking] joellinn:
Yesterday, while reading a german thread i saw a guy who called the service hotline, telling them about some bad software behaviours, and the one on the hotline said that with win phone 7 everything will be better...:D
[Windows Phone 7 Development and Hacking] NoSecks:
dont forgett the "MoneyRulez reason"

if HD2 whould be upgradeable to WS7 , alot of HD2 users whould NOT buy a new original WS7 phone.

they whould "only" upgrade xP

------

i think thats also a reason why there "maybe" wont be a upgrade posibility for HD2

ofc still no proovement

thats why im relaxed atm...

still much time left guys :p keep cool.

also its not that we got a VERY OLD SLOW and bad device atm .

i could rly imagine- to use my HD2 for atleast 2 more years.

so far my 2 cents.... greez
[Windows Phone 7 Development and Hacking] vangrieg:
Exactly, and they would do it for free. Even if you charged them for the license, it's only 10 bucks or so, not 100 HTC would make on selling a new phone. How many people would be willing to pay $100 for the upgrade? Thought so.
[Windows Phone 7 Development and Hacking] RustyGrom:
LOL. So yo make a completely unsubstantiated statement like "WP7 already runs on the HD2" and you expect to not have to back it up?

You've officially gone off the deep end.

I'm not believing any "lies". There's no lies to believe! They haven't even made an official statement!
[Windows Phone 7 Development and Hacking] freyberry:
I know what I know.

WP7 upgrade for HD2 was almost certain, but last week, I got the message that it was getting increasingly unlikely for "political" reasons. No matter what they tell you, there are no technical issues and the button story is just a pretence.

Sure, you don't have to believe me either... but if you rather believe the crap MS tells you... your fault. I don't care ;)

I'm getting an Android phone next month, anyway... why would I want to deal with a doomed OS anymore? WM6.5 is almost dead and WP7 is a locked-down iPhone-OS-like crap, so... whatever.

(and by the way, they say WM6.5 will live alongside WP7, but the truth is, development of WM6.5.0 will be stopped soon and WM6.5.x will only be developed for a few months from now and they have no interest in keeping WM6.5 alive longer than absolutely necessary - they're even talking internally about killing it in about 12 months instead of the 18-24 months they planned earlier)
[Windows Phone 7 Development and Hacking] gogol:
LOL ...

You keep saying "WP7 already runs on the HD2."

Now it is obvious that you just open your mouth telling bul****.
[Windows Phone 7 Development and Hacking] freyberry:
Obvious? Only thing that's obvious is that you have no clue at all. Go on believing the bull**** MS tells you... but don't blame me if you ever find out the truth... I told you so.
[Windows Phone 7 Development and Hacking] Shasarak:
Of course you don't, it's just that you've been so spectacularly wrong about so many things recently that no one is going to believe a single word you say from now on unless you do.
[Windows Phone 7 Development and Hacking] freyberry:
I've not been wrong about anything.

How should I be able to prove WP7 runs on the HD2? Not possible. I don't have it. And I also won't tell you any names. I promised people not to talk about details, and of course, not to tell anyone their names. I'm not going to break my promises just because some forum members rather believe Microsoft's bull**** than what I know...

Anyway... I know I'm right. I don't care if you believe it or not. It's your problem, after all ;)
[Windows Phone 7 Development and Hacking] Shasarak:
Well, I never mentioned the bootloader.

"Architecture" was a poor choice of word, on my part; I meant something more along the lines of "the driver in the beta version needs to support every feature that even a later version of the OS might ever attempt to invoke" and "every hardware component has to be activated in the beta"; I can imagine that an early OS beta might not use some of the minor components (like, say, the proximity sensor) at all.

I can't agree with you about the chassis specs, I'm afraid. The specs simply specify minimum levels of performance, on the whole, they don't require specific components. They might say that the camera must have a certain minimum resolution; they don't specify that a particular camera sensor should be used in all WP7 phones. So unless there is a Microsoft-written version of WP7 running on a phone which has an identical camera to the one in the HD2, there's no way the camera will ever work on the HD2 under WP7; unless there is a WP7 phone which uses exactly the same capacitive touchscreen component as the HD2, the touch-screen will never work under WP7; and so on. Of course, if there is a fully functional version of WP7 running on the HD2 already, and if it leaks, we'll be fine; but that's what I said in my previous post.
[Windows Phone 7 Development and Hacking] RustyGrom:
They haven't said anything about WP7 on the HD2 except "wait for MIX" so there's nothing to believe or not believe. It's obvious to everyone that the button issue isn't a technical one but rather a issue of conformity. If you want to call this "political", fine. They're trying extremely hard to keep out the fragmentation that took place in WM previously and allowing any exceptions to the rules will add fragmentation (as trivial as it may be in this case). No doubt the "experience" won't be as good on a HD2 as a real WP7 device since you'll just have to remember that home = search (or whatever they decide).
[Windows Phone 7 Development and Hacking] freyberry:
No. The "political" reasons I'm talking about have nothing to do with buttons.

The button story is just a pretence.
[Windows Phone 7 Development and Hacking] RustyGrom:
A pretense for what? You can't just throw around supposed inside info as facts on a message board with absolutely no proof or past history of trustworthiness and expect that people will just believe you.
[Windows Phone 7 Development and Hacking] freyberry:
Of course I can.
[Windows Phone 7 Development and Hacking] vangrieg:
Whatever the reasons and consequences and reality of this decision are, they are, IMO, much more interesting and to the point here than discussing whether freyberry "really" knows something or not, with all due respect. I think most people here should be mature enough to make their own conclusions. Just my opinion.
[Windows Phone 7 Development and Hacking] RustyGrom:
Yes but we don't know what those decisions are so then there's nothing to discuss at all if you throw out his baseless accusations.
