Re: @Richard12

Renewables have their place. The Gobi, Sahara, most of Southwest USA, etc for solar (and wind in some cases). Solar is more likely than wind turbines to give decent returns. Wave (tidal) turbines are a good start too, but the best move forward would be nuclear plants. With huge amounts of electricity available at fractions of the cost of power today, electric-only cars, trains, equipment, etc would take off in a big way. Imagine proximity chargers (induction or otherwise) under parking stalls at Walmart (or just plugs, either way), down freeway stretches, at the employee parking at work, etc. Your furnace would be electric rather than gas. Hot water would be electric rather than gas. Another big thing would be the readily available electricity for the fusion reactor experiments, since those take the power of an entire city (or more!) to actually get the reactor jump-started (and running, since they're not self-sustaining yet).

iPad 3 chip leak squeaks dual-core tweaks

Ammaross Danan
Boffin

Re: Cores

@Renato:

The performance metric that counts is the amount of RAM on the device. "Droidtards" have real multitasking, so they can switch between web-browsing (while it's loading) to pull up their playlist, pop over to a remote desktop window, jump back to their picture album, etc etc etc, all without causing disconnects (with the webpage or remote desktop), nor having to page RAM to/from the flash storage. Without this multitasking ability for iOS, they don't need to load up iDevices with more than their 512MB allotment. (iOS has limited multitasking for i-branded apps only, so yes you can play your iTunes music while surfing, I know).

Now, how to power all of these things, plus anything else that might come up in the next year or so you own the device? A quad-core chip should do it. Since the platform is threaded as a standard (unlike the Windows environment of yester-year), all 4 cores could actually get used. Zipping around on a single core with a 800x600 screen (or worse, the phone you cited) won't see much of a performance bottleneck (CPU-wise) with your apparent workload. Mine, however, makes even 1GB RAM dual core chippery fall over (props to the Galaxy Tab 10.1 for handling it best though). We'll see if the iPad2S can top what we can pick up today with the Asus Transformer Prime.

Apple goes to European Commission with complaint about Motorola

Ammaross Danan
Boffin

Re: How in hell can "standards-essential patents" exist?

The crux of the matter is that Motorola offered their FRAND licensing to Apple to an amount that falls within the "Fair and Resonable" licensing scheme (albeit likely the top end, but still within the limits), and Apple rejected it and STILL used the patented technology. Similar to Apple suing Samsung for using an OS (which they got from Google) that had rounded corners on icons that are arrayed in a grid on the screen. If the technology supplied by Qualcomm is the only infringment in question, and if the licensing to Qualcomm covers third-parties that use said Qualcomm chips, then Motorola doesn't have a leg to stand on. Of course, this is likely not the case, or else this suit would have been readily tossed already.

Intel pushes Ivy Bridge out a little further

Ammaross Danan
Boffin

Re: Only a 'Tick'

There's more than just a die shrink in Ivy Bridge. The tri-gate transistors and the bump in integrated graphics performance just to name two. Need more? Extra PCIe lanes, PCIe 3.0 and native support for USB3. The die shrink and tri-gate transistors alone allows them to drop the core voltage fairly significantly, thus saving power.

My money is sitting until Ivy Bridge comes out. I doubt AMD will come up with a suitable competitor by then (not holding my breath with Piledriver), which is why Intel can sit on their stockpile rather than slash prices a bit to shift it.

Re: Re: Pure marketing ploy

"...while Intel is also troubled by its Sandy Bridge processor inventory, the CPU giant plans to delay mass shipments of the new processors to minimize the impact"

So, because their CPUs are still priced high (just shy of launch prices, due to no real competition from AMD), no one buys their chip stocks en masse, so rather than slash the price a bit to shift them, they'll just sit on their current prices until their stockpile goes down.

Come on AMD! This is what competition is supposed to prevent!

Laser boffins blast bits onto hard drive at 200Gb/sec

Ammaross Danan
Boffin

Life Span != MTBF

"OCZ VERTEX 3 SATA III 2.5" SSD 240GB life span is 2 Milion hours."

Mean-Time Between Failure is not "Life Span." Here's an example from a reference:

Example: "MTBF of 100,000 hours. [This figure] indicate[s] that in a population of 1,000,000 batteries, there will be approximately ten battery failures every hour during a single battery's four-hour life span. This is because during that one hour, the 1,000,000 batteries were operational for a sum of 1,000,000 hours; dividing total uptime (1,000,000) with MTBF (100,000) we get the average number of failures."

So, one SSD in a group of 2mil dying every hour, while good odds, doesn't ensure your drive won't pop its clogs in the next 2 hours. Next in line is that mainstream mechanical drives barely crest the 1mil MTBF mark...

As for write-endurance, I've heard of numerous drives having hardware/firmware deaths, but not many (if any) write-endurance problems.

Revealed: Apple's plea for fairness in mobile patent war

Ammaross Danan
FAIL

Default Rate

"...would like the threat of injunction removed from all FRAND patents, so no one could use a FRAND patent to have anyone else's products removed from the shelf."

So, in Apple's case, if you reject licensing a FRAND patent, due to being asked the high-end of the stick of a "fair and reasonable" price, simply because you wanted the El Cheapo end, and go ahead and make the product anyway expecting to just fight it out in courts (if it comes to that, as it's expensive for SMBs), you don't get the right to block said company from selling the device and are simply left with spending millions in court to get your previous "fair and reasonable" royalty they owed you legally anyway?

Samsung Series 7 Chonos 15.6in Core i7 notebook

All Roads Lead to Rome

When you design a laptop, there's little you can do to get a "solid" feel. Sure, they could carve the laptop case out of steel, but that wouldn't satisfy the weight category now would it? Aluminium it is. You can see this in PC cases, steel for cheapos with aluminium for higher end.

Keyboards have some potential variation, but chiclite style is still fairly common, no big news there. Black keys on an aluminium surround? Oh noes.... At least they're backlit.

Various designs stray into the realm of blending trackpads, minimizing the bezel, or going for a designer plastic casing vs metal. Why Samsung didn't pick one of these other options? The question to you is, "Do you think it's fugly?" Why would they pick those other designs if you answered "yes"?

Fortunately, all this consideration and market research was unnecessary for Samsung to conduct, as it could simply ape the hodge-podge that Apple tossed together.

Symantec: 'NetBackup 7.5 speeds backup 100X'

NetBackup complexity

Yes, NetBackup is more complex. rsync would only be part of the Big Picture. You still wouldn't be able to do client-side dedup (disk/processor intensive), but you'd at least get a synthetic backup with inline compression during transport. rsnapshot would help you manage backup snapshots, similar to NetApp, but at a far worse disadvantage. Then there's the matter of CPIOing it to tape or the like, which NetApp can handle in spades (as long as you like managed tape sets). The advantage your rsync/rsnapshot has is cost, at the expense of "lets hope it keeps working." Granted, NetApp becomes a black box appliance as well, but at least it has commercial support....

Foxconn tooling up for iPhone 5

Fair Response

Nice constructive response Sparticus. My allusion to 6mo-old tech is in comparison to selling tech, not development tech. When the iPad2 came out, it sported a 800x600 resolution, which had been exceeded by other manufacturers. It had a slower core-clock. Definitely half the RAM of other products. Apple does a wonderful job of putting a pretty bow on top of near-top-of-the-line kit, but selling it at premium.

HOWEVER, what were the chinese polishing which contributed to the dust which exploded? iPADS! Not a plastic-framed HP, IBM computer or Nokia phone.

Retailer drops Eee Pad Transformer Prime, claims quality issues

Ammaross Danan

Well aware

I'm well aware of the "price it high to stab the initial buyers" of economics. The point I was making is that the Prime isn't stabbing at a lofty starting price (such as is done with graphics cards) and sinking down to a "reasonable" price. Much like the iPad (when have you seen the iPad2 base model "sink" in price?), it is sold at a fair price and doesn't necessarily "sink" toward an "equilibrium" price. Hence the comparison. I'm just pointing out the obvious benefits of the product; no "iRage" required.

"...as they pay more..."

It can be had, with the keyboard dock, for under $500, which is better than the iPad of similar 16GB storage can claim. Only things that beat it would be sub-par 'droid-based tablets of a dual-core (or less!) variety. I, for one, am glad they stuffed it with a quad-core chip, decent RAM and storage, and pitched it at a price-point to make one seriously pass over a Galaxy Tab...

Narrowmindedness

Yep, a load of crap forced upon the workers by management is a common plague. I was in the fortunate position to steer our midsized biz away from tape backups (had 4 servers with tape drives, just to pull the data in time for nightlies, granted the CTO wanted full nightlies...) to a D2D2D method. Unfortunately, there's not many affordable solutions out there for how we wanted/needed to do it. A NetApp VTL gets halfway there, but that's a 5-digit figure for an "almost fits" solution. Needless to say, a Linux server and some development time, we have a proper functional system now. Not quite as clean as a pretty packaged NetApp server, but it does precisely what we wanted.

TrueCrypt

I don't know of a common encryption system that isn't vulnerable if the password has been entered and the machine is still on, but TrueCrypt is a great option still. For one, they're aware of this RAM issue, and they actively wipe the RAM that contained the valid decryption key when you properly unmount a TrueCrypt volume or shutdown. Therefore, if you want security, just unmount your volume or shutdown the system properly (don't yank the plug). You're safe. As for decrypting a TrueCrypt volume, they may be referring to the same type of RAM vulnerability to do so. I doubt their rainbow tables or dictionary attacks will work against a TrueCrypt volume with a decently long password (15+ chars) and a keyfile or two. Rainbow tables used to crack WEP were several TB in size.

RAM

RAM contents have a decay period. When you power up a computer normally, RAM registers are reset to zero automatically, since they may contain latent data. If you take a RAM stick and stuff it in a device that is designed not to do this, you may be able to read the contents if you're quick enough.

Therefore, REGFAIL for not explaining such, and YOUFAIL for not reading up first. :)

Snaps confirm new CPU for Apple iPad 3

Just determine your Total Cost of Ownership. Fortunately, you have an iPad1, so you likely have all the dongles and adapters needed to interface with common stuff (computers, speakers, tvs etc). You can get a Transformer Prime with the keyboard for less than the 16GB iPad2. How much does the bluetooth iPad keyboard cost? The Transformer keyboard even comes with a battery pack the size of what's in the tablet. Plus, you can get it NOW. Not a hard decision really, considering the "rumored" items are just what the Prime already has (minus the supposed screen resolution and the obvious assortment of Android-common connectivity slots).

A few comments

Joe: "i'd expect people who are buying higher end GPUs to be more likely to opt for an SSD instead of a traditional HDD."

You can't squeeze Battlefield 3, World of Warcraft, Crysis 2, and other such games onto a 120GB SSD comfortably, nor does it make much sense to do so. These gamer enthusists likely would need additional storage for multimedia and the like as well. Just because someone is willing to pay ~$400 for a video card (or two) doesn't mean they'll fork out for an upgrade on a computer on the eve of the Ivy Bridge launch, or the eve of the new Radeons and GeForce cards. And they certainly would avoid paying premiums on new HDDs when their old one(s) can be carried forward.

Article: "And the higher prices of disk-drives constrained some PC OEMs' ability to include a GPU in their systems"

That should likely read: "And the higher prices of disk-drives constrained some PC OEMs' ability to include a GPU in their systems, forcing them to realize there's a GPU built into the CPU nowadays anyway." (since most are flogging Intel, or pushing a cheapo AMD with on-board (integrated) GPU.

Sad News

The sad news is, RAID5 (and now default RAID6) is the cheapest way to maximize storage space with as few disks as possible. (10x2TB disks in RAID6 gives more space than 10x2TB in RAID10 for instance.) Unfortunately, RAID10 is in the same (but slightly better-but-worse off) position as RAID6. To rebuild a RAID10 failed disk, the system only needs to access a single disk and copy it verbatim. However, with an unrecoverable read error on the single disk (less likely than would happen in a RAID6 btw, do the math!), you end up in the same pecarious boat as RAID6, with less disk space, but better performance.

Now, this segways into the next point to take: SSDs bottleneck RAID cards in any form of checksum (RAID5-ish) setup. Now, with how the firmware for SSDs are designed, a URE is extremely less likely compared to a whole-disk failure, thus proving them likely more ideal in a striping environment (also considering that in a mirroring setup, each drive would theoretically have the same exact writes and wear, assuming the controller doesn't use an RNG for allocation or cleanup, thus suggesting near-same failure times, which isn't seen as often due to varying endurance for each cell). Side note would be that the drive would fail in read-only mode, thus a "custom" RAID solution could use it to rebuild most/all of the replacement disk....but I digress. Disk storage will still be the leader when it comes to shear data storage, thus the need to address resiliency in RAID. An interesting thought/solution would be a RAID0+1+1, which would scale slightly worse (available space-wise) than RAID61, have 1disk less worse-case resiliency, but a lot better rebuild performance and rebuild resiliency (as the first RAID0 would work at full speed and the second would be used for mirrored reads (think read striping across mirrored disks as well as across the stripe), and the one disk that is the second mirror to the disk that failed can be soley dedicated to restoring the missing drive. (Don't bring in the primary, as it would cause head-thrashing on the target rebuild disk since 2:1 read:write would only work if it was appropriately striped reads). A single URE would be protected against due to the dual mirror remaining, or if you're unlucky single disk remaining. Any involvement of checksumming would unfortunately hobble any SSD implementation of such an array, but for disks, it could be acceptible. The caveat for a RAID011 is that it has worst-case resiliency on par with a triple-checksum stripe (RAID7 I believe). It just has the benefits of having low processing overhead and near RAID0 performance even in "degraded" mode, which could be more important than the lower resiliency in some/most cases.

Any other thoughts or flames?

AMD readies answer to Intel's Ultrabook

Ammaross Danan
Boffin

Trinity will have a slighly upgraded GPU compared to Brazos, however Ivy Bridge will have a significant step up in GPU from Sandy Bridge. Will it bring enough performance to compete against an integrated Radeon? Not a chance. They're mainly trying to include DX11 support and pump out a few more FPS. Trinity's biggest weakness will be the Bulldozer cores, which would hobble any GPU beefier than the built-in one. This is where Ivy Bridge will excel, allowing Intel to significantly underclock/volt their laptop-binned chips and maintain on-par performance (with Trinity) at significantly lower TDPs. With an add-on wifi chip, it will use more power than the built-in WiFi planned for Ivy Bridge, so :( to that too. Will the price save AMD? Likely, as raw CPU performance is no where near as important (or noticable) for the lay user nowadays. The battery life will be a decisive factor though, separating out the long-lifers from the perma-plug users.
