The State of ZFS On Linux

rrohbeck Re:Unfamiliar (366 comments)

The same can be said for any file server and workstation. I still don't understand why ECC is so unpopular.

The State of ZFS On Linux

rrohbeck Re: Unfamiliar (366 comments)

Hmm, does it get faster on a bigger CPU? 8x3TB gives you 500-600 MB/s with a HW RAID6.

Intel Discloses Core M Broadwell Speeds, Feeds and Performance Expectations

rrohbeck Re:Tick/Tock has become NOP/NOP (60 comments)

Well as long they have little competition why should they push anything?

I can only hope that AMD and TSMC or GloFo will do something about that.

NRC Analyst Calls To Close Diablo Canyon, CA's Last Remaining Nuclear Plant

Some experts say it's because shale gas expanded too fast so that a glut depressed the price and nobody made money any more.

The Quiet Before the Next IT Revolution

rrohbeck Re:Ah yes (145 comments)

Moore's law was about a one node shrink every 18 months, meaning a reduction in structure sizes by sqrt(2), i.e. twice the number of transistors at the same die size. The reduction in size meant a reduction in gate thickness and operating voltage by sqrt(2) and a reduction of capacitances by a factor of two. Those allowed an increase in clock speed of sqrt(2) at constant power. None of that is happening any more.

NOAA: Earth Smashed A Record For Heat In May 2014, Effects To Worsen

rrohbeck Re:GLobal warming scien is simple (547 comments)

The carbon increase in the atmosphere can a) be compared with the amount of fossil fuels burned and b) has a different isotope isotope composition because 14C has only a few thousand year half life so fossil carbon is practically devoid of 14C. Not speculative at all, falsifiable and tested.

ACTA is back

rrohbeck rrohbeck writes  |  about 2 years ago

rrohbeck (944847) writes "From eff.org:

The shadow of the Anti-Counterfeiting Trade Agreement (ACTA) is back in Europe. It is disguised as CETA, the Canada-European Union and Trade Agreement.

A comparison of the leaked draft Canada-EU agreement shows the treaty includes a number of the same controversial provisions, specifically concerning criminal enforcement, private enforcement by Internet Service Providers (ISPs), and harsh damages."

The $25/£15 computer from the UK

rrohbeck rrohbeck writes  |  more than 3 years ago

rrohbeck (944847) writes "Electronics Weekly brings us a report on the Raspberry Pi, a computer the size of a USB stick with USB (for keyboard/mouse/network/storage), composite/HDMI video out and power connectors and a memory card slot. It runs a 700MHz ARM11 with 256MB of memory and is designed as a teaching tool, envisioned to boot Ubuntu right into interactive Python like the BASIC computers that got many of us hooked on programming.
There is a lot of interest from developing countries and chances are that there will be a buy one, give one program.

"There is an energy barrier at the start of the learning curve," said Upton. With the Spectrum or the BBC micro, even if you only wanted it to run a game, you turned it on and it immediately said 'BASIC' and you could write
>10 print "Hello world"
>20 goto 10.
A lot of us got sucked in by that and became programmers."

PCs just don't cut the mustard."

Apple engineer builds Antikythera out of Legos

4KB disk sectors are coming

rrohbeck rrohbeck writes  |  more than 4 years ago

rrohbeck (944847) writes "Anandtech brings us an article about WD's campaign to increase disk drive sector size to 4KB, and the reasons behind it. They are basically better format efficiency, better error correction, and less overhead everywhere. Every modern OS uses at least 4KB block sizes, but some may create misaligned partitions, making the use of alignment tools or even 512B sector emulation necessary.
Now when we re-align everything, can we please think of SSDs too and align partitions and everything else on at least 1MB boundaries?

It's been a long time coming — I remember talk about this from 5 years ago or so."

Amazon US refunds Windows license fee too

rrohbeck rrohbeck writes  |  more than 5 years ago

rrohbeck (944847) writes "Today Amazon credited my card with $65.45.

After ordering an Eee PC 1005 HA from amazon.com, I asked them for a refund for the cost of Windows XP via the "Contact us" form. At first they told me to cancel any items on my order that I wanted a refund for, but after I explained that XP was preinstalled on the machine they got it. They asked what the cost of the OS was, and I answered that I had no idea but that Amazon UK refunded GBP 40.00. Within a few hours I got a response saying "I've requested a refund of $65.45 to your Visa card."

Somehow I doubt that Amazon will charge Asus or even Microsoft, but maybe they will one day if more people do this.

Eeebuntu 3.01 doesn't have network (wired or wireless) drivers for the new generation of Eee PCs, but Karmic Alpha-3 does and looks quite good already. I love the Launcher! Now let's see how long the battery will last if I run Linux only off the SDHC card and don't spin the hard drive much. Voila, poor man's SSD.

Oh and peeling off the "Designed for Microsoft Windows XP" sticker is easy too."

British teen 'saved by Facebook'

'A British teenager who took a drugs overdose has been saved after the American girl he was chatting to online raised the alarm.
The 16-year-old boy from Oxfordshire had sent her a message suggesting he intended to commit suicide.'

The girl in Maryland told her parents, who called the police, who went from the White House via the UK embassy to local UK police in Abingdon, Oxfordshire. They found the teen in the fourth house they checked."

YouTube music videos blocked in the UK

"YouTube is blocking all premium music videos to UK users after failing to reach a new licensing agreement with the Performing Right Society (PRS).
Thousands of videos will be unavailable to YouTube users from later on Monday."

So I guess they'd rather have no licensing revenue from YouTube and force UK users to learn about proxies and P2P."

Forry Ackerman dead at 92

In recent years he had to sell the "Ackermansion" and most of the about 300,000 items of memorabilia it stored due to mounting health bills. The LA Times prints an obituary today."

Site against California's Prop 8 being DoS'd

rrohbeck (944847) writes "A site against California's Proposition 8 (Gay marriage ban) is apparently being subjected to a DoS attack.

eqca.org reports:
SACRAMENTO — 10/30/08 — Today the NO on Prop 8 campaign's Web site (http://www.noonprop8.com/) was the victim of what appears to be a coordinated attack designed to bring the system down. According to http://www.calitics.com/, the denial-of-service attack (DoS) on the NO on Prop 8 website occurred before 11:30pm, Wednesday, October 29th and coincides with a similar attack on Florida's NO on 2 campaign, the Constitutional Amendment Against Marriage Equality.

The verdict, delivered by a jury 3,300 miles from his home in Girdwood, Alaska, comes just eight days before Election Day, when Stevens was hoping to win re-election to an eighth term.'"

Vanadium batteries for renewable energy

rrohbeck rrohbeck writes  |  more than 5 years ago

rrohbeck (944847) writes "Compensating for the intermittent nature of wind and solar power needs conventional power plants to fill the gaps or large scale energy storage like hydroelectric.
Large batteries, for example based on the sodium-sulfur system are an alternative. Discover magazine runs an article on recent improvements with the vanadium redox battery, which is another system that can provide MW/MWh batteries. The smallest ones are "closet" size, so don't count on them for cars — yet, but they could be an option for UPSs too."

North pole might be ice free this summer

rrohbeck rrohbeck writes  |  more than 6 years ago

rrohbeck (944847) writes "The north pole might be without ice for the first time this summer, reports The Independent. 'It seems unthinkable, but for the first time in human history, ice is on course to disappear entirely from the North Pole this year.'
'Seasoned polar scientists believe the chances of a totally ice-free North Pole this summer are greater than 50:50 because the normally thick ice formed over many years at the Pole has been blown away and replaced by huge swathes of thinner ice formed over a single year.'
Although melting of floating ice doesn't increase sea level, it's a sign of major thawing in the arctic, and 'If it happens, it raises the prospect of the Arctic nations being able to exploit the valuable oil and mineral deposits [...] which have until now been impossible to extract because of the thick sea ice above.'"

The brightest Gamma Ray Burst ever

rrohbeck rrohbeck writes  |  more than 6 years ago

rrohbeck writes "The universe honored Arthur C. Clarke's death on March 19 with a record number of Gamma Ray Bursts overall and the brightest GRB ever observed: GRB 080319B.
At a distance of about 7.5 billion light years, the associated explosion was the farthest object ever visible to the naked eye for a short time and the intrinsically brightest.
Space.com has an article about the event detected by NASA's SWIFT satellite and observed by many others."

rrohbeck writes "The New York Times has a story on what Blue Origin, [Amazon.com founder] Jeff Bezos' space company is up to after his Texas land grab. A couple of Flash videos show a short successful test hop of the "Goddard" test vehicle.

The Goddard has a science-fiction sleekness. Videos show the craft taking off and landing again with a loud whooshing sound. In one view, one of the nine rocket nozzles jitters as it maintains the ship's attitude. Goddard resembles the DC-X, another vertical-takeoff-and-landing craft under development in the 1990s by McDonnell Douglas for the Defense Department and NASA until the government pulled the plug.
And in case you're an aerospace engineer, they're hiring."
