I will take it positive, I don't think you are arguing.

I do not understand what you are looking for. The link you have provided (http://www.mckinnonsc.vic.edu.au/vce...tion/index.htm) gives a diagram of what a Pilot and Parallel deployment looks like.

Pilot:


In this image it shows the new system being deployed to a small group while the old system is still being used. At some point in time the decision is made to end the pilot deployment. At some later point in time the decision is made to directly convert the entire user base to the new system or to convert the user base in phases.
Parallel:


In this image it shows the new system being deployed to a small group while the old system is still being used. At some point in time the decision is made to directly convert the entire user base to the new system or to convert the user base in phases.

You have already answered your own question, you have the resources before you to figure out:
... what are pilot approach and parallel approach with regard to s/w deployment and maintenance.
What part of that are you still having trouble with?

yes ... of course :) ... just answered more things at once and guess i mistyped it then ... so ... #5 of course :) - since that should be the answer of the OPs teacher ... that is just confusing in regards to the things that are shown on the OPs provided link ...

I wonder if what he really means is the Quality driven practice of 2 Developers working together on a single Keyboard as apposed to a Single Gatekeeper who drives the development and all modules and developments are handed to the gatekeeper as a build owner?
Working as a Programmer and Analyst since 1989, I have heard of many terms that Marketing people like to come up with that have no or nearly no difference in the physical world, and only refer to a method of looking at a solution or approach, so when I see Parallel Development, I think of 2 things, 2 to 1 developers, and Back End + Front End at the same time, and tie them together after the prototype at the business layer.
When I look at developments from experience, and with 0 Failed projects in my life of over 40 projects, I have found Front to back to be more productive and successful, using the XP approach, give the users a Prototype screens to play with, and build the BL and DB to fit, with some DB common sense. I have also found that rebuilding the prototype is not required, if you build the prototype as a template architecture, you can use it in the final build if the differences are minor. but expect some Input or output to be thrown away/replaced or added to.
I am sorry I am not answering your question directly but sharing actual business experience in a fast changing environment.

Hi! We're doing a research project that involves controlling mini-windtrap speeds and we're reading/writing data from the parallel port. What I've found so far on a fast Google search for "python parallel port" showed me some stuff that I'd have to interface with Python through SWIG. If the program could be portable in Windows and Linux it would be a big

I'm interested to know what ideas are out there for reading a parallel port at a constant sample rate while still allowing the user to interact with the GUI. That is, reading it every 10ms for example without exception. Is this at all possible? Current tests done show that if the sample rate is 10ms then this is acheived in general, but when another program loads or terminates this 10ms jumps up to 100ms or more. In these tests the code is...

I'm wondering, is there any way I...

For example, line L1 and line L2 are two lines in two-dimensional space, the start-points and end-points can be described with following the `point_t' type. The start-points and end-points are: Line L1 (L1_str, L1_end), L2 (L2_str, L2_end). Can I compare the float value of sloping rate of two lines to determine whether they are parallel lines? Some paper books tell that float value can not be compared to float value. Some people also try...

Take a class, RateTableProductCode. It needs to share implementation with other classes, so the common code is placed in a ProductCode class, from which it derives. There needs to be an IRateTableProductCode interface so that objects can be mocked for testing. That interface also has a common interface which is shared with other interfaces, and that goes in IProductCode. This all makes sense to me, but I just have a nagging feeling that...

Has anybody tried to run parallel python applications? It appears that if your application is computation-bound using 'thread' or 'threading' modules will not get you any speedup. That is because python interpreter uses GIL(Global Interpreter Lock) for internal bookkeeping. The later allows only one python byte-code instruction to be executed at a time even if you have a multiprocessor computer. To overcome this limitation, I've created...

Hi there, I have a question on a naive implementation of a parallel MT that I've done using the fortran version of MT19937ar.f posted in Prof. Matsumoto's website.

Hi, there are some concurrency frameworks available for .net from microsoft, which takes advantage of the cpu. But recently GPUs have broken the 1 tera flop barrier and are really ideal for parallel computing. For example Nvidia's CUDA allows us to program the GPU. My question: is there any effort going inside microsoft that would give us (the devs) some framework, which wraps up the functionality of CUDA (or similar technology from...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
