Don't assume that a "low" version number means it's unusable. The project has commits going back to at least December 2009. Not all software is versioned with the assumption that 1.0 = finished.

Startup Claims C-code To SoC In 8-16 Weeks

unts Algorithms vs. hardware (205 comments)

Algorithms only work well if they fit well with the hardware they're targeting. You have to make certain assumptions, but depending on what your algorithm is, you should know which things you really need to think about (memory, branching, process communication, disk, ...)

Algorithms that get synthesised into hardware will only work well if they're written in such a way that lends itself to synthesis. There's going to be a huge heap of stuff that doesn't fit well, or doesn't work at all. Writing things like Verilog and even System C is very different to writing a piece of software. And let's not even mention the backend stuff like layout - stuff that can have a big impact on performance of the thing you're spending a lot of money fabricating (oh, I guess I /did/ mention it...)

So, maybe a bit ambitious, but if they've solved even some of the problems and helped bring software development and hardware design closer together, well, that's a good thing.

DARPA Targets Computing's Achilles Heel: Power

unts Re:let me answer that with a question (100 comments)

The problem is not just generating the power... it's delivering it and consuming it without breaking/melting. And that's what they're getting at here - getting more FLOPS per watt... not finding out how to push more watts into a system. A silly amount of the energy going into a supercomputer comes out as heat... and a silly amount of energy is then used to remove that heat. Hopefully, by significantly improving the energy efficiency of chips and systems, we can make them a lot more powerful without them needing a whole lot more power. And I haven't even mentioned the mobile/embedded side of the spectrum where its about battery life and comfortable operating temperatures... the same energy efficiency goals apply.

This is the sort of thing we over the pond are very interested in too. Like for example *cough* the Microelectronics Research Group that I'm a part of.

For some services such as wifi there are instructions for various flavours of OS - Windows, Mac, Linux, Android. We have Enterprise WPA2 and the university requires you to install their certificate, but they've done a pretty decent job of documenting it for these OSes. Unfortunately some of the software they advocate is very Microsoft or Windows centric. The Computer Science department goes quite a bit further - its lab machines run CentOS. Up until a couple of years ago there were some old Sun machines knocking about somewhere in the Engineering Faculty.

What's the Oldest File You Can Restore?

unts Backup, or archive? (498 comments)

10 years is not that long, but more to the point, if I am looking for a file on media that is so old, then it must be archived not backed up. A backup is something you keep if you want to safeguard against loss of data on whatever you use as an active data store. An archive is somewhere safe you keep something when you no longer have a regular need to access it, but may still need it in the future. The methods and media for backups and archives are often the same/similar, but in the case where you have something archived, one would assume there is no "live" copy and therefore the archive should itself be backed up.

Given the rate of storage capacity expansion and my comparatively pedestrian storage requirements, my archive policy is that it stays on my computer, and simply doesn't get accessed. That way it's always backed up using my most current backup regime (rsnapshot at the moment), my "archive" isn't really an archive at all, and I don't have to worry about the media getting old, because it's guaranteed to be on my most recent media - the media I use daily.

The iPhone Serial Port Hack

unts Re:Not a secret (217 comments)

THANK YOU!

This is so far from a secret it's not even funny. Imagine if we'd only just discovered what those two pins on the connector did?

Hell, even the breakout board the guy (who's original, non full page ad-encumbered article can be found here) bought has the bloody serial pins labelled.

It's not remotely surprising that an embedded device has a UART on it. It's even less surprising that a device designed to interface with very simple dock devices has a UART exposed via its peripheral connector.

What is surprising is that the combination of breakout board and RS232 line driver somehow managed to be bigger than the phone.

unts Smug UK citizen here (637 comments)

Half of these I don't even need to consider:

Health insurance - We don't pay directly for healthcare here because we are communists.
Birth control pill prescription - I'm male, but ignoring that, contraception is free
Current account with non-pharma drug provider - I don't know what this is but I assume it's somehow related to the two I've just mentioned above.
NPR membership - Why would I want to be a member of the North Pennsylvania Railroad anyway?

Of those that are left, I don't own a car, live in a city that you can walk around quite easily and don't use a gym.

So all I have to choose between is my mobile phone or my landline/broadband. I'll take my landline thanks - there's plenty of public wifi around here (or friends willing to give our their WPA PSK).

DRM applied to furniture manufacture: Chair self-destructs after 8 uses

unts unts writes  |  about a year and a half ago

unts writes "Taking DRM further than it's gone before, a group of designers have built a DRM'd chair that will melt its own joints and destroy itself after 8 uses. The chair uses an Arduino and sensors to monitor the number of uses, then triggers the melting of a set of joints that hold it together, making the product unusable without some carpentry skills. The video of device at work is both amusing and a little disconcerting... could a company decide that this is a genuinely good idea? Maybe some more spectacular pryo effects would make sure nobody tries to circumvent the DRM measures."

Wire-up your home with no extra wiring: Powerline Ethernet Wallplates

The product is essentially a replacement wallplate for electrical receptacles that includes four powerline ethernet RJ45 connections, providing connectivity throughout a building without the need to run CAT 5e/6 cabling. Performance appears to be good (better than the 802.11n router tested, at least), but what's to stop you simply using regular powerline ethernet adapters where you need them?"

MythTV 0.25 released, new HW acceleration and audio standards support

unts unts writes  |  more than 2 years ago

unts writes "The highly configurable Linux PVR, MythTV, has reached the 0.25 release, over 500 days after the previous full release. New features include VAAPI support, E-AC3, TrueHD, and DTS-HD audio, the ability to control other home entertainment devices via HDMI CEC and additions to the API to allow HTTP live streaming. The release notes for 0.25 don't reflect the release status at the time of writing, but should contain most of the relevant changes.

MythTV can be used as a backend (recorder) and frontend (viewer), but can also feed other frontends such as appropriate versions of XBMC. Hopefully the new HTTP streaming API will lead to even more ways to get your video fix from MythTV."

ARM unveils next gen processor, claims 5x speedup

unts unts writes  |  about 4 years ago

unts (754160) writes "UK chip designer ARM today released the first details of its latest project, codenamed "Eagle". It has branded the new design Coretex-A15, which ARM reckons demonstrates the jump in performance from its predecessors, the A8 and A9. ARM's new chip design can scale to 16 cores, clock up to 2.5GHz, and, the company claims, deliver a 5x performance increase over the A8.

"It's like taking a desktop and putting it in your pocket," said [VP of processor marketing — Eric Schorn], and it was clear that he considers this new design to be a pretty major shot across the bows of Intel and AMD. In case we were in any doubt, he turned the knife further: "The exciting place for for software developer graduates to go and hunt for work is no longer the desktop."

Should German lawyers be able to tell UK media wha

unts unts writes  |  more than 4 years ago

unts (754160) writes "Recently a German mini-notebook manufacturer took exception to Qualcomm's use of the term "smartbook" to refer to ARM powered mini-notebooks. Smartbook AG set about a legal campaign against Qualcomm and has obtained a temporary restraining order in Germany. But the firm hasn't stopped there, seeking to litigate against any media outlet that dare use the word "smartbook" when referring to ARM based notebooks. HEXUS recently fell foul of such a lawyer's letter, but isn't keeping quiet about it:

[...]why has Smartbook AG sent us this letter? Surely they can see that the genie is already out of the bottle. Furthermore, it hasn't even registered the trademark in the US, China, or countless other countries so what does it expect to achieve by threatening a few European journalists? Also, we can't find any evidence of Smartbook AG selling its products outside of Germany. How can it register a trademark in countries where it has no presence? Our feeling is that it's an indirect way of pressuring Qualcomm into settling the matter out of court and buying the trademark for as high a price as possible.

Qualcomm is disputing the restraining order in Germany, and Smartbook AG has stated its desire to sell the trademark."

ARM Linux Shipped With Dell's New Latitude Z

Dell says the system boots in 2 seconds and comes with Firefox installed. They significant news here is that Dell has opted to include a distinct set of hardware to run its instant-on solution — one using ARM's IP. If this optional extra proves popular, then it could assist ARM and its licensees in competition with Intel, and indeed Linux in its battle with Microsoft. HEXUS.channel reports that Dell isn't likely to make this a one-off, either:

We asked the big question: is Dell thinking of offering ARM-only products in future? "It's not in our short-term plans — we will probably have a mix," [Bohar] said. "You can use it for single tasks, but it's not really powerful enough to multitask."

ARM takes the fight to Intel, risks hurting its pa

unts unts writes  |  about 5 years ago

unts (754160) writes "UK CPU designer ARM is moving to make it easier for companies to produce systems containing ARM processors. The company is offering up "hard macro" implementations of its newest Cortex-A9 CPU, ready for integration into System-on-Chip designs, reducing the cost and time involved in designing and testing them. In doing so, it claims it is upping the ante in its battle to beat Intel in the mobile and netbook spaces, and indeed beyond. This is a departure from the existing so-called "ARM ecosystem" whereby its partners must come up with the hard implementation of the cores themselves. However, HEXUS.channel mulls over the possibility of such a move creating issues with existing partners who've already invested heavily in their own ARM-based designs:

The likes of Qualcomm and NVIDIA didn't spend zillions of dollars developing Snapdragon and Tegra respectively, only to find themselves having to compete with numerous other entrants to the market, all facilitated by their supposed partner ARM. This could be an additional reason for ARM to continually make such a big point about how its targeting Intel.

Intel's new mid-range i7, i5 chips tested

unts unts writes  |  about 5 years ago

Steve Kerrison writes "Today the lid is lifted on Intel's new Lynnfield mid-range processor models, with such names as Core i5 750, Core i7 860 and Core i7 870. Making sense of all the model numbers, HEXUS examines the new Core i5 and i7 models, explaining the difference between them and existing Core i7 processors along with a brief look at the new P55 chipset. The chips are then benchmarked against other Core 2, Core i7 and AMD Phenom chips.

Intel's decision to release new processors based on the potent Nehalem architecture has been long overdue. There's been little change in the previous 10 months, really, as the chip giant's harvested the range-topping LGA1366 architecture for all it's worth. Now, though, the introduction of the Lynnfield range of CPUs will see Intel transition much of its mid-to-high-end stock to LGA1156-based Core i5/i7 CPUs.

Asus' single-PCB, dual GTX 285, 4GB graphics card

unts unts writes  |  about 5 years ago

Steve Kerrison writes "Despite a lack of new high-end graphics chips from Nvidia and AMD so far this year, add-in-board manufacturers are finding ways to make the most of what's already out there. Asus has gone the route of outrageously outlandish, by designing and manufacturing a dual-GTX 285 on a single PCB and equipping it with 4GB of memory. That probably rules it out for 32-bit systems, then. Hexus has an exclusive look at the showboating graphics board, dubbed the Asus ROG MARS, examining its construction, performance, power consumption and heat output.

We can think of ten reasons not to buy one, easily, but also one immutable rationale for throwing down a lot of cash for the MARS. It's fundamentally outlandish enough to be cool — a sheer brute-force approach to graphics. If you win the lottery or are lucky enough to work for Goldmine Sachs and it's bonus time, buy a bit of history... and a 5GHz Core i7 to get the most out of it. Everyone else wistfully laugh at the exuberance of ASUS' R+D department.

ARM hopes to lure Microsoft away from Intel

unts unts writes  |  more than 5 years ago

Steve Kerrison writes "With the explosion of netbooks now available, the line between PC and mobile phone is becoming much less distinct. ARM, one of the biggest companies behind CPU architectures for mobile phones (and other embedded systems), sees now as an opportunity to break out of mobiles and give Intel a run for its money. HEXUS.channel quizzes Bob Morris, ARM's director of mobile computing on how it plans to achieve such a herculean task. Right now, ARM's pushing Android as the OS that's synonymous with the mobile Internet. But it's not simply going to ignore Microsoft:

What if Microsoft offered a full version of Windows (as opposed to Windows Mobile or Windows CE) that used the ARM, rather than X86 (Intel and AMD) instruction set? Then it would be a straight hardware fight with Intel, in which ARM hopes its low power, low price processors will have an advantage.

Morris wouldn't be drawn on whether this will ever happen, but he seemed quietly confident it would, pointing out that Microsoft will be missing out on an increasingly large market if it doesn't. "The pieces for fundamental change are already within the industry," he said.

ATI vs. Nvidia on Linux - The State of Play Today

unts unts writes  |  more than 5 years ago

Steve K writes "Historically, Nvidia has been regarded as the better candidate for providing 3D acceleration in Linux. But with more people than ever dipping their feet into the desktop Linux pool, AMD/ATI has responded by increasing its Linux driver efforts. HEXUS's Jo Shields takes a look at a pair of beefy graphics cards, one Nvidia, the other ATI, taking a look not just at 3D performance, but also at accelerated video playback and their control panels. FTA:

So who is the winner of this heated battle then? You are — the consumer. Whilst NVIDIA still came out on top, it did so with only the smallest of margins in most cases — and you can feel confident that owning a Radeon is no longer a blocker to a decent experience in Linux.

Hooray for consumer wins."

The company has issued a letter to a number of speed test websites stating that it will be testing the testers — so to speak — in order to share with potential and existing customers the accuracy of the tests they're using to determine the speed of their net connection. The company has a vested interest in ensuring speed tests have suitable testing capacity — it will soon be launching a 50Mbps cable service in the UK.
