I was searching for new visualization libraries in Python, and I learned about the existence of Pyvista. The examples I've seen look amazing.
I used to work with Mayavi a few years ago, but Pyvista seems very tempting. Are the features in Pyvista really as well-rounded as traditional libraries like Mayavi, etc.?
The question can seem opinion-based, but sometimes new libraries need a few years to become complete. I learned this the hard way with some CAD packages.
I intend to use Mayavi to post-process results from CFD simulations (computational fluid dynamics). Please let me know your opinions.
Thanks in advance,
As PyVista is just a wrapper for VTK it's safe to say that you are not restricted in what is possible.
I found the move from Mayavi to Pyvista really straight forward. The library has a couple of functions that allows you to convert your existing data structure into VTK friendly structures quite easily.
And if you were a fan of Mayavi's pipeline work there is something similar in PyVista where you can add on different things to do plotter.
I hope that helps. Also, join the slack channel if you want to ask any questions / see what other people are using it for.

I want to go with Xamarin.Forms project. Now, I am bit confuse for consuming Rest API for this project. Performance matters.
There are many available but can any body please suggest me which should be best for Xamarin.Forms(.Net Standard)?
Microsoft Http Libraries or third party libraries like Refit, RESTSharp, PortableRest, etc.
Please suggest
All of these options are viable. I think the performance differences between these libraries will be marginal. So, it mostly comes down to what you feel comfortable with.
I like to use Refit because it will take a lot of redundant code out of your hands and you just have to focus on the contract. All the code for the actual calls is generated at compile-time (and thus won't impact your performance at runtime).
Also have a look at how well the library is maintained and if it's active. If you choose one that is already inactive for a while, chances are that you will start relying on older software versions which might not be what you want.

So I am trying to buy a low cost accelerometer to use with my Arduino and PIC projects. I don't know much about them, and would appreciate some advice.
I have come across two which interest me: the ADXL345, and the MMA7361. Those seem to be the cheapest around with a good record. If there are any others, please let me know what you recommend - or help me choose between these two.
With that said, I was looking at the ADXL345 on eBay, and found something weird.

The one in the first link is cheaper, but also smaller. It seem like the same thing as the second, but I am wondering why it is smaller and looks like it has less components. I do know it is missing the pins, which I can solder on myself if I purchase it. But anyways, why do they physically seem so different?
Thanks in advance everyone!
Looks to me like the 2nd link includes the pull-up resistors for the I2C interface. Hard to tell on the 1st link though.

What is the best way to write the system requirement specification. Definition is given to me. project scope is very heavy.
Which model should i approach to get the detailed requirement from the client ?
Which are the common mistakes while gathering information from client and writing specification ?
Help appreciated.
First of all, you have to have a background in requirements engineering. As a start, look at the Volere templates, that help to organize the requirements in a meaningful way. The authors (the Robertsons) have written a book "Mastering the Requirements Process" (ISBN: 978-0321419491), but there are of course a lot of other authors.
There are a lot of techniques to get requirements from the customer, and it depends on how the customer behaves, in which area he is under way, and how much experiences he has there. It is not possible to give here any advice.
I don't think that there is a list of common mistakes that could help you in any way. Get an experienced requirements engineer, and follow his steps.

I currently use Kile to edit LaTeX documents. I don't like kile for a couple of reasons so I was thinking of trying to learn how to use texmacs. I have been through a tutorial for emacs which I am now getting to grips with. The documentation for texmacs and auctex are pretty weak in terms of explaining how to install and how to use those things. A quick google search didn't show up any friendly "how-to"s on this topic. Are there any resources you can direct me to?
I'm a bit puzzled by your question. I use Emacs+Auctex on Windows, Linux and OS X machines and have never had any problem installing them. I'd suggest heading to http://www.gnu.org/software/auctex/ and following the instructions. If you have any more specific questions post again.
sorry I can't help you with TeXmacs, I just wanted to note that this program isn't under active development for quite some time now. If you look at the homepage the copyright notice is until year 2003!
If you are looking for a more GUI oriented LaTeX editor I can recommend LyX. Emacs+AucTeX is of course wonderful, but it has a certain learning curve.
However if you plan to learn Emacs or are using it already, than you should definitely go for it!

Developing software solutions which already exist and are available for re-use (either commercial or open-source). AKA "re-inventing the wheel".
Same as above, but your solution being broken. AKA "re-inventing the square wheel".
Developing solutions for problems which do not exist.
Again, I'm interested in a more formal approach, e.g. TRIZ
Doing some research beforehand (1) and investing in solid software architecture (2,3) usually helps :)
When you're planning to develop something you always need to calculate the benefits of doing some and the things like the ROI.
