I've just tried out the "scientific" (i.e. landscape) layout of Galaxy Note 8.0's stock calculator - and it seems that it outrageously mishandles trigonometric functions !

Just a reminder that
sin(n*pi)=0
cos(n*pi)=1
tan(n*pi)=0
tan(pi/2) is undetermined
tan(pi/4)=1
tan(pi/3)=sqrt(3)=1.73...
So this begs the question, "WTF???!!!"
Don't forget that those values are only true when your angles are in RAD. All calculators are in DEG by default and that is why you get those "wrong" values (which aren't wrong since they are correct in DEG mode)
Hope you figure out how to change it to RAD I'd help with that but I only get my Note Monday/Tuesday

Thanks, man, I haven't even thought about that!..
Having the arguments of trigonometric functions in radians is virtually always the default, though!.. At least for a "scientific" version of a calculator. They should at least give some indication that it's in degrees... I don't think you can change it to radians, by the way.
And why have the Pi constant, then? The only use for it that I can think of is within trigonometric functions. Well, and calculating the circumference of circles.

Maybe it's because Pi is a constant?

Pi is a constant yeah and I think its used for stuff other than trig I just can't think of anything my school mode is off lol my phone's calc is in RAD for those functions but I've also had to use the same functions in DEG previously so there is use for both. In physics (mechanics) we mostly used DEG for these!
I read around you can download a calculator from the Play Store which allows you to go from RAD to DEG and vice-versa but can't remember the name sorry

Well, I know Pi is used for other stuff, I have a PhD in mathematics.
What I meant was that among the functions included in Samsung stock calculator's landscape mode trigonometric functions are the only ones that can make any sensible use of Pi. The only other use I can think of (within this calculator) is, like I said, using Pi to calculate circumferences and areas of circles.
And I understand that one can dowload other calculator apps - but this doesn't change the fact that, to me, this behavior of the stock calculator is weird.

A thing I've noticed when showing people swype, is that the faster a typist you are, the easier it is to learn swype. I type 120 WPM myself, so I have a pretty good mental picture of where all of the keys are.
This is why android is #1, customization.

Hello! I'm a designer who loves Metro. I'm tired of seeing the lackluster Metro app design currently plaguing the Windows Store. While there are some fantastic designs, many apps are just boring or don't fit in well with the Metro design language.
I'm here to help. I'm offering my design skills at no cost, all I ask for is one line of credit in the app's About page.
This is my first design. It's a complete GUI for Instapaper. It's very clean, modern, and most certainly Metro. It's extremely simplistic, but still has everything you could want from an Instapaper app. This app rivals even the official Android and iOS Instapaper apps. The design is based around the Bing News app and the People app. If you're interested in developing this app, I feel you could charge at least $3 in the Store, and make a good profit, which I would want no part of.
Below are some images. I have PSDs of every interface from the log in to creating a new folder. If you're seriously interested in developing this app, either send me a message or post below.

Aaaagh... don't quote huge OPs like that, please! Just hit Quick Reply and don't use the "Quote message in reply?" option. It just makes the page really long and makes it hard to find the breaks between posts...
To the OP: looks very nice. I hope you find a dev to work with. A few things to keep in mind:
1) Different resolutions, and scaling between them. What looks great on the Surface's 1366x768 will look pretty bad on my desktop's 2560x1440.
2) Different aspect ratios. Tablets in particular are sometimes used in portrait aspect ratio. It would be great to have a good UI for using the app like that too; not enough Store apps handle that well.
3) Snapping the app to one side or the other. This makes it much thinner and also removes the ability to open the App Bar (right-click or swipe in from top/bottom) and Charms bar for that app, so if it's going to be useful in the snapped view it should offer the most critical controls directly to the user in this interface. Skype, Xbox Music, and even Mail do decent jobs of this, although they aren't necessarily pretty.

I do have designs for every view/position (I haven't done anything about scalability, but I have ideas on how to work with that). I only posted the two main views in dark/light varients to make sure people could get a good solid understand of how it will work and function. I have PSD's for almost everything that's needed. I've found someone who says they'd like to work on it.

You should undertake overhauling a well known open source windows software. Most of them dont have a metro counterpart. Just pick anything, i can see you have a pretty functional design understanding.

If you guys are talking about the stock app, how can you say it works perfectly when the dimensions of the app force you to use more than three quarters of the screen to use it? Could you recommend one that uses half the screen, because if I am expected to give up so much real estate for it, it would be better to completely switch from one app to another. I had thought the whole idea of multitasking was to do more than one thing at a time.
EDIT
Honestly, if you guys are just attempting to be rude, I'd rather not have the help because I was intending to get answers to a serious question.
If the video player that comes stock didn't show the full dimensions of the movie but "worked perfectly" with multi window by merely running and displaying half of the screen, I doubt that would be good enough for you. Of course, you could just expand the window to get more of the picture, but that defeats the purpose, doesn't it?

I second aircal, I use it on jellybam (no multi-window as it is AOSP) but floating calc = better the multi-window calc since you can have 3 things up at a time then lol.
Of course the calc is not super feature rich, but for general math it is good enough for me.

Thanks. With the dev name, I was able to find it. Without it it seemed as though you were talking about the stock and I didn't know any better. It was pretty far down the list, but I found it and I will try it out. The screen shot surely looks much more promising then the stock one on our devices. The Air also looks to have even greater utility and I will give it a look as well. Thanks again.

This clarification helped immensely. The app works truly flawless. This is the answer.
Hey everybody. I'm working on a pretty big app the requires very accurate measurements from the accelerometers. As we all know those thing have noise like mad. So I decided to do some experiments and I'd like your feedback.
Experiment setup:
Record sensor event into a custom buffer while to phone is at rest and then moving it up and down a few time, left and right, back and forth. (In this case I used MPL linear acceleration and and Inverted the measurements based on the rotation matrix sensor to get directional linear acceleration vectors not affected by orienatation).
My results had shown that at rest, my phone was accelerating between -0.5m/s^2 and .5m/s^2 WHILE AT REST.
I took these data point which were samples at about 100Hz and upsampled the data to 44100Hz using linear interpolation because I'm a lazy bum. When I'm finished collecting data I then write it out to three files which represent the data from the X, Y, and Z axes. The format I used for writing the data was as 32-bit floats (big endian). I wrote all of this in java BTW.
Next I imported this data into Audacity to get a visual representation of the data. Using audacity also gives me some tools to reduce the noise.
This is a sample of the data I worked with unfiltered (the at rest data is in circle in red and the up-down motion is circled by yellow):

}
I then got the noise profile of the at rest segment and used it as a noise-gate and got the following result:
That looks a lot smoother and also that little blip on the left is the acceleration caused by my finger leaving the screen after starting the app (I think). It appears that the accelerometers are still just as sensitive, but not as noisy.
So with this, method I have two options, since this algorithm is open source and originally written in C++ I can implement in the kernel as a new Virtual sensor in libsensors.so. I think this would not be nearly as heavy on the CPU. Dince the algorithm is really just a few FFT operations. Or I can port the algorithm to java that way there is no need to screw around with the kernel.
Comments, thoughts, suggestion, critiques, complaints?
That's amazing. I'd like to see this implemented.

I just finished implementing the algorithm in java. I have a feeling it will be somewhat frustrating when I run the code. There were a few hacks I had to do just to get the java code to compile. I wanted to do the quick and dirty, so I pretty much just ported the algorithm as best as I could. The original algorithm called for a CharBuffer which in c++ is char *variableName, since I'm working with floats I'm converting it to a floatBuffer. Also they use their own custom implementation of FFTs so I have no clue how jTransform will handle it. Finally every method seems to be static so from a data comparison perspective, I have a feeling that this is going to cause all sorts of weirdness. Hopefully I'll have some result data posted around 4PM EDT. This time is very tentative since I have to prep for a HUGE meeting for work.
Update delayed
Hey everyone just wanna let you know that the algorithm is doing something but not what I expected and I have a meeting to go to so I'll try to give you all a more thorough update tonight.
Kind of found the issue
I kind of found the issue with my unexpected result, when I exported the noise clip it appears it wrote it as little endian floats, I'll try to resolve this and hopefully post some results (again). I have a better feeling about this algorithm than I initially had
Where I'm at in my progress
As I'm waiting for my code to compile (code not related to this project). I'd thought I'd show you some of my latest results.
This is a garbage result. It appears that something goofy is going on when I'm writing out the data (which is interpolated as the data is being written). This is certainly showing the noise cancellation doing something though.
Willing to see it!

The watch is only made with the light background. I can invert the image and desaturate the blue tint, and you'll have a black background with white/grey markers and text. What I will not do is recreate/photoshop out all the markers and just replace the background with black and keep the markers in gold, as that is way way more work than your original request. If you're ok with the black/white look, I can easily do that.

There is no second hand on my watch, as the original DW doesn't have it either, neither does the image on your OP. It's only hour and minute. As far as changing the image when it's dimmed, it's just a matter of duplicating the layer, changing the opacity and setting that to show when dimmed, and setting the original layer not to show when dimmed.
I'm not entirely sure if you're talking to me thinking of this:

All three of those somehow, magically, appeared online after I created mine based on your request.
If none of those three are what you want, I can modify the one I made. But I don't want to waste my time, so check those out and let me know.
Thanks, I will try and muddle through the settings. Still very new to this. I am using Watchmaker, and will play around.
There are some of the watches I like, but I use ambient setting, and for some the watch face disappears and only the hands remain. Others have a second hand that freezes in ambient mode, then jumps around when it activates fully.
If that even makes sense.
Thanks for all the work, you do a phenomenal job.

Watch Face does not lack 12 hour support. It's using the standard tag. You can also just change that yourself in Facer by opening the layer for the hour hand and changing the rotation tag.
