By that measure, isn't AMD also fabless because TSMC makes their chips? (or at least their big processors)
I guess what I mean by "making" is "designing and having someone fabricate for them". That is what would set it apart from all of the other ARM chips out there today.
Linus made this argument in a different forum yesterday (paraphrasing from memory): "Look, something has to be authoratitive when it comes to parameters. On a linux system, that's the kernel".
Which is aribitrary, but not without merit.
No. This is the kernel command line we're talking about, after all. Its original intent is to be used to send options and information to the kernel and, by extension, kernel modules. The fact that user-space programs can read/proc/cmdline and get options passed in from the bootloader (e.g different menu entries) is frankly a hack. The least any user-space programmer should do is make sure their chosen strings don't clash with already-existing parameters. Re-using the "debug" flag is inappropriate, even if it didn't flood dmesg and hang the system.
I saw an amazing example of how the stations screw up their use of HD just a few months ago. Channel Ten was showing a live F1 race on One in SD, while their HD channel was showing Fast Foward (or Full Frontal?) from the 90's upscaled to 1080p. Wow.
It consists of an inherently lossy encoding in the frequency domain (like MP3) plus an encoding of the difference between the lossily encoded audio and the original.
While a few other lossless formats do this (mostly for backward-compatibility), FLAC does not convert the audio into the frequency domain. It either uses a polynomial or linear function:

Those hardkernel boards sure are interesting but lack the GPIO of these boards. I think a better comparison is to the Cubieboard. It also has a 1 GHz Cortex-A8 with lots of GPIO pins, but has 1 GB of RAM, 4 GB of flash and a SATA port. It's also a bit more expensive, but I'm pretty sure TI has been subsidising the Beagle boards.
In the mid-00s, more and more people started learning about Android...
Android was announced in 2007 and the first Android phone wasn't sold until late 2008. Even the Neo1970 was from 2007/08, so I don't know what the submitter is referring to.
The ARM ISA may seem "complex" when you describe it like you have, but each instruction is still a fixed size, they all follow one of only a limited number of formats (R-type, etc), and memory is only accessed by load/store instructions. That's why many prefer the term "load/store architecture". Anyway, these things really help to simplify your instruction decoder stage and keep memory accesses simple. These in turn make it easier to implement things like pipelines, out-of-order execution, branch prediction, etc. And that's only the stuff that has been implemented in ARM so far. I wonder how long until ARM develops a core with more advanced features, like register renaming and specularitive execution, and how it will perform then compared to x86 (which already has these things).
He has a long history of saying stupid things and then mostly failing to wiggle his way out of the ensuing controversy. The guy's just a twit, basically. You can tell he's not very bright.
Would some Aussie please fill us in... what is this for?
It's to cover polititian's arses. Even though we've never had a real problem with terrorism, no polly wants to be held responsible for "not doing enough" when/if something does happen.
The ARM architecture provides a lot of integer performance, with little to no floating point performance.
That hasn't been true for a while now. Floating point support (in various versions of "VFP") have been standard since ARMv6 (e.g ARM11) and were optional in ARMv5 (e.g ARM9, ARM10, XScale). ARMv7 (e.g Cortex-A8/A9/A15...) has NEON ("advanced SIMD") as an option that most licensees also include. So ARM cores now have pretty good floating point performance too.
Oh, that's right. Hasn't Broadcom licensed any of the Cortex cores yet? No wonder they're able to make them so cheap; they're several generations behind and ARM Holdings mustn't be charging much in royalties.
How far behind? Well each of the Cortex-A9 cores in this OMAP 4-based SoC perform about 2.5 times better than ARM11 at the same clock speed. So each one could get about the same amount of work done as the 700 MHz ARM11 while puttering along at only 280 MHz. The dual-core OMAP 4460 running at 1.2 GHz has about 1200 * 2 * 2.5 / 700 = 8.57 times the processing power of the Raspberry Pi. Hmm... $25 * 8.57 = $214.29. So the $187 price of the PandaBoard ES (subsidised by TI) may be worth it!
The secret ingredient is Nvidia's five-core Tegra 3 chipset
You really think these compact machines use sets of chips? Quite the opposite. They're systems on a chip (SoC), often even a package on a package (PoP) i.e multiple chips layered into one package. Now, don't get smart and point out that technically a PoP is a chipset - they're used for packing an SoC with DRAM and flash memory. The multiple functions of a chipset (e.g peripheral interfaces) are all on the one chip of the SoC.
The anonymous poster gave a good answer, so sorry for repeating some of what he/she said: I mean "fake" as in they did everything necessary to get the degree (exams, assignments, lab work, etc) but then publicly denounced the subject and made statements that flat out contradicts everything that they studied/said/wrote in getting the degree. An example is someone getting a degree in geology and then supporting the idea of the biblical flood as a factual event. They'll say that radiometric dating is wrong and that rocks, fossils, and geologic formations were all laid down in the flood about 6000 years ago. They'll use the authority of their degree (often from a prestigious university e.g Harvard) to give credence to all the crackpot "alternative" explanations that are necessary to support their dogmatic beliefs.
The problem is not that they don't "believe" the subject of their degree. One normally gets a degree with the intention of applying the knowledge and/or skills you've supposedly attained. Using it merely as a prop and misinforming the public is bad faith (somewhat ironically). And for the institution there is the problem of reputation - it could easily raise questions about the institution's selection and grading criteria.
Tell them the only way they'll get a degree from a respected institution is to not be an idiot.
Sadly, there are now a few creationists with degrees in things like biology or geology. They manage to fake their way through uni/college and then go on the creationist lecture tour circuit touting their degrees. It's the classic argument from authority fallacy: "I have a degree, so everything I say is factual. God did it. Really. I have a degree."
Studying religion(s) doesn't necessarily mean you have to practise or believe it. In fact, studying religion is quite likely to result in you seeing religion as just mythology and not believing it.
The architecture puts ARM into more direct competition with Intel and its 64-bit Xeon processors.
Gee, what about AMD and the AMD64 architecture that they developed? You know, the one that Intel eventually had to adopt (license?) when their 64-bit Itanium didn't quite live up to their expectations of being the next architecture that everyone moved to?
Oh, and ARM Holdings don't make chips. They design architectures and implementations that others license and put into actual chips. The summary wasn't so clear on that, and it's a point that lots of people often overlook.
Your economy is in the crapper, Australia's isn't. We're doing pretty well, partly thanks to our mining sector selling raw materials to China. We also had a recession back in 1987 due (from what I'm hearing now) to bad assets. It had the result of (eventually) clearing out all of those bad assets and leaving our banks stronger than before. So when the GFC hit everyone, we were able to weather it rather well. You guys haven't, and you haven't gotten rid of the toxic assets that caused it in the first place! We're all in for more pain...
I'm sure most people here will go on and on about how it's not FLAC, and whatever.
Maybe. But the nice thing about lossless encoding is that there's no generational loss. So just transcode your FLAC rips to ALAC to send to your Airport thingies. Still equivalent to the original CD!

Wait... is ARM making its own chip? I don't think they've done that since like the ARM1/2.

This is still OTA, just digital.

its not the vendors. don't blame them. its the creator of android.
Yeah, just look at how badly Google's Nexus devices are supported compared to phones/tablets supported by their manufacturers. It's terrible!
