unit testing - How do I incorporate TDD into my workflow as a scientific programmer / student / researcher? -

-

I'm busy! Most of my time is spent on analytical techniques, or of course, and when I switch to programming mode, I have to prepare the code quickly because the primary investigator for the lab does not care if I I am using TDD or Abacus, I can get results.

I have read "TDD by example" and found it very useful I later found "Refactoring: Improving the design of existing code", "Design Pattern: Elements of Reusable Object-Oriented Software" And "working effectively with the Code of Heritage" but these books are big and the possibility of jumping in them is now challenging!

The interactive style and flow of "TDD by example" made it easy to incorporate into my timetable. But, I do not know how to work in these books and in what order; It appears that each bus is as relevant (I'm in a type of dining dalcher deadlock - I'm waiting to improve every aspect of my programming toolkit, but their interdependence has referred me to gridlock or timing Lost - Sorry Analogies :)). Like I have a code of heritage that should be restructured and covered with a test, I need to use TDD (but I have never done it), I need a code with a design pattern, so I I stop the search of wheels.

Is it a good way to break reads in the size of the byte size and one way to do this while applying its techniques for existing projects (personalized form , I lose information if I can not apply it immediately)? Do I focus on a book and complete it? Do I need TDD for the first time, refactoring and design pattern skills (but 'chicken and egg' all these unit testing books talk about design patterns and refactoring as I know them backward and forward)?

I have read, but it explains how I integrate it into busy schedules. And, I have read, but again reminds me how you can add these techniques when you are already behind schedule.

The details of what you do have been given, I ask questions on first impression. I do not know anything about the complexity of your programs, but if your coding generates creative calculations and this means "script-level", which means that you can easily get it out for a given code It can be retyped as it is, and one of these techniques is too much, I think that TDD (probably an added version that is included in the integration test. Will always be valuable), but beyond that, not necessarily.

If you are actually developing software systems (and at least if you are doing this, you may also be eligible, even if it is not all, for example database models, input Screen, result distribution), so I should read enough of these books to get started, and do not worry about doing it properly, at all times for the beginning, just make sure you are making measurable progress every week.

By the way, design patterns can be useful to read about how similar problems are addressed, but not to "design them to use". It may not be good, but the patterns come from the real world design, not by other means. So you can certainly see more object-oriented solutions, what you can do, but worry Do not do what you are doing, fit in the design pattern, make sure that whatever you are doing is a good maintenance design on your own terms, and these patterns will flow over it.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
