It's difficult enough getting many embedded engineers to go to C over assembly. In the ARM world, C is the standard for programming, but for lots of other devices, such as the MSP430, efficiency and deterministic behaviour is really importa

I don't know much but it's a bit of a mess. You're right that there's a reverse engineering effort but it's against the 400 GPU, not the 704 in the Exynos. Samsung has been under quite a bit of pressure to open up the GPU code, and they've

It was more a case of hard clipping vs soft clipping. You could get tube ( valve ) amplifiers moving high tension volts way over spec at the cost of lots of third harmonic ( mostly ) distortion by providing things like DC amplifiers. Semico

See clearing banks. When transferring monies between unrelated accounts, and often financial bodies, the amount is held in clearing bank limbo. One reason for this is that so aggregated amounts from one entities account can be offset agains

I'm doing mostly embedded work on ARM chips at the moment. Which is a world away the rooms of Sparc V9's I've also worked on. It's a tighter space and you can't use too much of C++'s bigger bits. But multiplexing an SPI bus with C++ for exa

Nothing against Lightroom though. It's one of my favourite programs from Adobe, together with InDesign. And I've heard that about Aperture, and recently FCP.

C++ doesn't have to be complicated. It involves such a compoundingly convoluted tool box however that you can create overly complicated contraptions that can explode right in front of you. There was one fundamental decision made back in the

That's very interesting. I didn't know that about Lua and Lightroom. It's interesting for me as I'm asked a lot by photographer friends about large performance problems with Lightroom. Particularly between versions 3 and 4. Huge number of i

I've noticed that. Travelling on suburban trains in Melbourne was a constant din, especially if there were groups of school kids on the train.

It is a lot harder to work with these phone and tablet type chips. ARM have open sourced the Mali driver code but you still need the DDK, which requires a license. The reverse engineering efforts on GPU command streams are also a labour of

I do believe that it's closest siblings are Chromebook and Nexus 10. Graphics benchmarks are slightly under the Nexus 10 but that could be due to a number of things. [1] For me the main interest are the schematics and fudging a quad core wh

I find it amusing that our general perception of politicians, and of their real efficacy is such that no one can seem to work out if she's really playing dumb or not. The fact that it seems entirely feasible that she could be, says quite a

I'm not trying to bicker. I'm merely pointing out that VAT is completely irrelevant to tax on profits. It needs to be left out of the conversation as it never forms a liability for a VAT registered entity. It's only connection to ethics as

I see this misunderstanding over VAT in this and other posts on this subject. To be clear, VAT registered entities do not pay VAT in the fashion you imply. VAT is due on a VAT invoice. Companies usually do not do business with sources that

You don't seem to understand VAT. Consumers pay VAT on goods and services ( some exceptions ). Without further financial activity, these receipts are simply forwarded and paid to HMRC. For purchases that included a VAT component, ( and that

They could make terms and conditions plain by prefacing the movie with a big banner saying 'YOU ARE BEING WATCHED'. I'm sure the EU would enforce such a notion, just as they do cookies now.

Well, keeping to this example, there are sometimes conflicting requirements. A transient with a long train decay, such as a crash cymbal or knock, explosion or gunfire for example requires a wide view to properly observe the full affect. Th

I'm afraid this doesn't work in all cases. When working in a reduced physical area, irrespective of pixel count, zooming in and snapping to boundaries is counter productive. Audio wave editing for example is an operation on cyclic ( obvious

Well after my comment above about scaling resolution by moving back through the z plane, thank you for the link. It's really helpful.

I agree very much on this. There are some precision tasks that I do, such as audio waveform editing, circuit boards, photoshop image masking and so on that can't be done efficiently without a pointing device, or a surrogate. When using the

I think you're right to criticise capitalism's approach to so called externalities. It's a convenience to not treat limited resources as depreciating assets, for the purposes of competitive advantage. And near space is a limited resource. A

It is expensive in the US compared to the other two countries I get sims for, the UK and Australia. In the UK I can get a sim and monthly plan for my iPhone for around £6, which gives me what I need. In Australia it's about $30 for a month.

Relevant here is that Virgin Mobile USA is a completely different business to Virgin UK. Virgin USA is an MVNO on the Sprint network. As a joint venture between Virgin and Sprint, I wonder what actual involvement Virgin has in this area. En
