    Learning Assembly and computer architecture for x86

    Then for practice you better get a PC from that era. Highly likely won't work on modern PC, with modern OS - but even if you manage to make it work, it won't give you much useful knowledge. ...I may suggest to get 'Peter Norton's Assembly Language Book for the IBM PC' too from that era (a scan...

    Learning Assembly and computer architecture for x86

    It is all about learning to dissect the problem to lot finer steps than usual, while creating your own levels of abstraction from scratch fitting with the limited (CPU) resources while minding the environment you are working with. My humble opinion is, that it is kind of hard to get what...

    Learning Assembly and computer architecture for x86

    Kind of. The term 'embedded system' usually hints a more complex environment, often with some kind of OS: while the term 'microcontroller' can be just some minimalistic setup - the smallest devkit with minimal addons. As a beginner, what you will likely need is the IA32 as basis, from 1985...

    Learning Assembly and computer architecture for x86

    It's just assembly these days is not used for general programming on x86. It'll be very hard to get any real, useful, relevant experience apart from some variations of 'hello world'. That's why I recommended starting with microcontrollers. There, it's still possible to get the full experience.

    Learning Assembly and computer architecture for x86

    It is just that But using assembly in a sophisticated OS environment or within a C code is more about interacting with the framework, not really about interacting with the CPU. That's why I suggested to look for controllers first. There assembly code may run alone, and the project will still...

    Heating pad element sizing

    A small hot water boiler may fit that (set at low temp), but then you need to heat the outlet pipes too. ..on second thought a salvaged electronics itself still could be re-purposed to keep the temperature an enclose water body below the steel plate: and so the whole matter about the required...

    Learning Assembly and computer architecture for x86

    Z80 and 6502... That also gave a very good example about what is RISC and CISC...o0) That 'modern x86 assembly' is a very special, barely existing niche. In general, by now x86 programming is such a monstrous and complex topic that assembly is very rarely used, and, to be honest: coding on and...

    How do people explore new ideas in physics?

    Sure. Physics has that pesky 'reality' thing above all, what makes a difference: those who did not prove beforehand to be able to walk the walk will have clear difficulties. I think you will need to prove two things really carefully in a paper. First is, that there is significant benefit: this...

    Net metering - hybrid solar inverter system question

    You can start by looking up manufacturers for biogas and micro-hydro system components.

    Gravity in science fiction movies

    As I recall, there was several studies about the expected effects (not just coriolis, but many other) at different ring diameters and the minimal recommended diameter (since many effects depends on the ratio of radius difference between feet and head).

    How could I make it so ferrofluid drops do not coalesce?

    I'm no expert in ferrofluids, but based on their composition I think it would not work. Even if you manage to disperse it into some uniform drop cluster, they can still stick together without coalescing. What I would try is to embed some iron dust particles into transparent epoxy beads, and...

    Working for defense company?

    Yep. It may speed up things if you start accumulating actual experience during university years, but as a fresh graduate anywhere where it's an engineering team you'll start at the bottom, and you'll do it with supervision (help). (It is not about the defense sector. It's about any serious job. )

    Working for defense company?

    I've never, ever seen any serious engineering work where just (school) education would suffice. It's always a long ride along senior staff to get the experience, knowledge, and in special cases: clearance needed for the job. As a a fresh graduate, you may be involved in doing the toilet there...

    Avatar (film): antigravity and unobtanium

    I think somebody there seen some superconductor-related levitation experiments, and added it to the plot without much thinking. So, I guess the idea was that to display the value of the superconductor material below those levitating islands had some magnetic properties assigned. Bad news for...
