How much RAM do I really need? My choices are 8, 12 or 16 GB. I'm going to use my system for programming, specially advanced numerical programs. By increasing RAM, can I execute my programs & numerical models much faster or it mostly depends on CPU?

Asked by Siavash about 10 years ago

More RAM will never hurt performance but it may or may not help. Some tasks are "CPU-bound" and some are "memory-bound," meaning some will top out your CPU first and others will run through all your memory first. The only way to find out is to measure your particular usage and see.

When I'm buying a computer I tend to buy as much RAM as I can afford: you save money in the long run that way because the computer will have a longer useful life.

Hello,
I am using GameMaker to create a small Jump and Run game but when i press the Left key it enters into a Main loop which basically stops the game. Please help ASAP as I need an answer quickly.

Not a clue, have never touched GameMaker.

How do you change a computer application to a mobile app?

Asked by smile about 11 years ago

Generally you don't, but your question gives me an opportunity to explain a few interesting aspects of software engineering, so here we go anyway.

Engineers (software and otherwise) talk about the concept of "coupling." This means, roughly, "If I change Part A of this thing, how much if any do I have to change Parts B, C, D, et cetera?"

Good design usually calls for "loose coupling," which means that you can change one part mostly or totally independently of all other parts. In other words, Part A is a "black box" to Part B: Part B knows that it can get Part A to do something, but it doesn't have to know or care how Part A does that thing exactly, so you can replace Part A with something completely different, and as long as it continues to do the same task that Part A did, everyone's still happy with it.

When you see the opposite, "tight coupling," that means parts work together more closely, and it's a bigger pain to change one, because you have to change many others. Once in a while this is done for performance reasons, but usually it means that the design or implementation is bad.

So as programmers we like to make chunks of code that don't overlap, that only do one thing, and that offer certain services to other chunks of code ("expose an API") without actually committing ourselves to doing those services in a particular way. These high-level chunks of code are generically called "modules" although there are plenty of other terms too, for different contexts.

In particular, if you have an application with a complex UI, you would have one or more modules that did nothing but the UI: a module to put things in windows onscreen, to know what to do if someone clicks here or types there, and so on. But there would be more modules that handle things behind the scenes. Imagine for instance a mapping app where you could either type in an address, or say the address into the mic. These would be two separate modules, as piece of text in a window is a very different thing than a pattern of sounds, but the meaning of the address "123 Elm Street" is the same in both cases, so both of these UI modules would talk to one common module in the "backend," which means basically all the code that does something that the user doesn't see directly.

And this brings us, finally, to an answer of sorts to your question: if you can get your hands on the source code to the original application (which if the application is proprietary good luck with that), and if the UI is loosely coupled to the backend, and if you know how to program in whatever language the application is written in, then you replace the UI modules with modules appropriate to a phone or tablet.

The rest is just details. Thousands and thousands of details.
