Comment Re:Very relevent for small target embedded stuff. (Score 1) 641

BS. Embedded development still happens on 8-bit controllers

And there's also plenty of ARM chips that don't run Linux (because they can't due to lack of a MMU), e.g. Cortex-M0...M4-based parts.

That's one of the nice things about small target embedded work. It covers everything from 8-bit to 32-bit, from simple (no hardware multiplier, no division in hardware) to loaded (hardware floating point support, MAC units, HW dividers), from slow (temperature logging) to fast (control loop running at 30 kHz requiring 3us latency).

Terrorists kidnap, behead, murder and rape people everyday. No one cares. Muslims force non-Muslims to live under conditions much worse than than apartheid and no one says a word. Palestinians explicitly target civilians in unprovoked attacks because the burden of peaceful coexistence isn't compatible with their need to humiliate and persecute filthy infidels. It would be nice is we could fight our wars honorably. It would be nice if we didn't have to fight at all. It would be nice if I could turn on TV to a news station for a year, and for once, not hear about Muslims murdering people while they gloat live on TV every single time. It would be nice if the left-wing media didn't immediately blame everyone but the actual terrorists.

Sometimes you have to do bad things to evil people or they will do much worse to you or your love ones. People will blame you. They will say you are evil. They will say you provoked all of this. No amount of logic or truth will ever make them see the reality of your situation. You will be blamed no matter what you do. The terrorists will always be "innocent." You will persecuted because they are cowardly hypocrites who will always blame the person who refuses to be a victim.

Have a happy Christmas and don't be a bloody terrorists.

Very true, but we don't win by becoming like Muslims ourselves.

Comment Re:C is relevant because it is low level. (Score 1) 641

C is important because it directly presents the actual machine memory model.

Well, not really. There are some architectures that were basically designed to be used with C (68k, ARM), but there are others (8051) where a C compiler need to jump through some major hoops.

And the C compiler still shields the programmers from things like stack frames or worrying about CPU register allocation.

Comment Small target! (Score 2, Interesting) 641

Depends mostly on compiler and toolchain availability on those platforms.

To clarify: "Small target" means memory (RAM/Flash) is measured in kB, sometimes even in bytes.

You still have Python-capable processors for embedded systems if you can't afford to learn C.

As far as target size goes, that thing does not qualify as "small target".

FWIW, I've been struggling with LPC4300 series processors.

Those chips look like they're on the large end of "small target". Cortex-M4s are already pretty beefy CPUs.

The open source toolchain is just so bad that your CPU hard faults on first attempted function call (most likely due to incorrect memory maps).

You can usually get pretty detailed reasons for a hard fault if you dig into the appropriate CPU registers (HFSR, etc).

I'd check the linker command file. Setting up a basic memory map isn't that hard - it's the not-so-basic stuff where things get interesting (copying functions to RAM for execution, etc).

For science to work you must be able to state an unpopular opinion and not get slaughtered for it.

No. You need to be able to present your research without being slaughtered for it. When it comes to opinion, scientists have the same rights and are subject to the same criticisms as anybody else.

How many white people do you see in professional sports?

Heaps.

Cricket, for instance, is dominated by white guys in Australia and England. On the other hand, India, Pakistan and the West Indies have very strong teams - why? Because cricket favours places where kids can play the game in the street. Genetics don't enter into it.

Another example: Aussie Rules versus Rugby. Aussie Rules has a disproportionate number of Aboriginal players, whereas Rugby (in Australia/NZ) is dominated by Maoris and Islanders (Samoans, Vanuatans etc). Are Aboriginals genetically pre-disposed toward Aussie Rules, or is it actually because they grow up playing and loving Aussies Rules (Whereas Samoans grow up loving and playing rugby)?

Describe SPECIFICALLY what it is that humans can do better than robots in the vacuum of space : And I don't mean meaningless tripe, I mean practical tasks to do with the point of going into space: to explore. Show how the need to perform this task justifies the extra expense associated.

[no response]

I take it from you lack of response that you cannot think of anything?

It would help if you actually read what I wrote:

Here is what you wrote: Deep sea drilling even has divers that go underwater for weeks at a time for critical repairs... doing things that are enormously expensive and even approaching costs for sending astronauts into space. I've highlighted the section that caught my eye. How much does going underwater cost? I couldn't find any figures related to the costs of divers going underwater to repair deep sea drilling rigs. I did uncover the cost of James Camerons DeepSea challenge (http://deepseanews.com/2012/04/shouldnt-we-be-more-skeptical-of-the-deepchallenger-dive/) which works out around 5 million dollars. I'm sure you would agree that 5 million dollars a person would not get you to LEO, let alone beyond LEO (which, thanks to the necessary delta V) starts at a floor 10x that of LEO.

In short, I was being generous.

Since you got this so wrong, I need not reply any further.

You don't get to decide.

After going through Ebola, who is really going to give a shit about this?

Ah but TFA says five American children have died of this - making it much more important to politicians than tens of thousands of Africans! It sucks but that's the way it is.

besides the obvious filtering of content, will Google also be limiting advertisements and tracking of kids searches?

I would imagine it will be targeting adverts at kids, and tracking just as much.

That's going to be a serious problem. I don't know about other jurisdictions, but here it's illegal to target advertising to young kids.

Right, but the adverts will officially to "inform the parents who are viewing with the child", just like all the adverts on children's television. Everyone will know that they are targeted ad kids but officially they won't be to comply with the law.
