FAQs about Mailinator

FAQs about Mailinator: "So if the government issued a subpeona to Mailinator to divulge emails or logs, you'd rat me out?

Holy crap, yes. I'm not going to jail for you, I have a boyish face and very (very) supple skin."

Bloglines | My Feeds (3516) (1): "I have this theory about the behavior of squirrels and how they are like certain large software companies, especially SAP, the giant Enterprise Resource Management vendor headquartered in Germany. But obviously the most interesting part is the squirrels, so let's start there.

You are driving down a street in your car and up ahead there is a squirrel at the side of the road eating a nut. You aren't on an intercept course, there is no way you are going to hit that squirrel. So what does the squirrel do? At the very last possible moment, rather than watching you drive by, THE SQUIRREL DARTS STRAIGHT FOR YOUR CAR, passing inches in front of or behind the front tires.

Why does he do that?

Obviously I'm a guy with too much time on my hands because I've given this quite a bit of thought."

IEEE Spectrum: Vegas 911: "He and his team are currently working on upgrades to IBM DB2 Anonymous Resolution, previously known as ANNA. A more sophisticated spin on NORA, ANNA, in Jonas's words, 'anonymizes' data before it is shared and analyzed. 'It's a new way to find a few bad guys without shaving down the Constitution at the same time,' he says. He also works on data privacy issues with the Task Force on National Security in the Information Age, run by the Markle Foundation, in New York City, and with the Center for Democracy and Technology, in Washington, D.C"

Shared nothing parallel programming - O'Reilly Radar

Shared nothing parallel programming - O'Reilly Radar: "Our small database footprint project had the goal of externalizing as much computation off the database engine - pushing this processing into share nothing parallelizable pipelines. So we also did such things as externalized serialization (no more using the database engine to dole out unique record ID’s) and eliminated virtually all stored procedure and triggers - placed more computational weight on these 'n' wide pipeline processes instead"

IBM's eight-core Power7 chip to clock in at 4.0GHz | The Register

IBM's eight-core Power7 chip to clock in at 4.0GHz The Register

The IBM documents have the eight-core Power7 being arranged in dual-chip modules. So, that's 16-cores per module. As IBM tells it, each core will show 32 gigaflops of performance, bringing each chip to 256 gigaflops. Just on the gigaflop basis, that makes Power7 twice as fast per core as today's dual-core Power6 chips, although the actual clock rate on the Power7 chips should be well below the 5.0GHz Power6 speed demon.
In fact, according to our documents, IBM will ship Power7 at 4.0GHz in 2010 on a 45nm process. We're also seeing four threads per core on the chip.

Mark's Blog : Pushing the Limits of Windows: Physical Memory

Mark's Blog : Pushing the Limits of Windows: Physical Memory: "The Memory Manager keeps track of each page of memory in an array called the PFN database and, for performance, it maps the entire PFN database into virtual memory. Because it represents each page of memory with a 28-byte data structure, the PFN database on a 128GB system requires about 930MB"

My Way News - AMD changes CEO as turnaround pressure intensifies

My Way News - AMD changes CEO as turnaround pressure intensifies: "One notable fumble happened in the aftermath of the original Opteron chip's success. A technical glitch delayed the launch of the Opteron's successor by eight months, forcing AMD to slash the price of its existing chips to stay competitive."

How Prozac sent the science of depression in the wrong direction - The Boston Globe

How Prozac sent the science of depression in the wrong direction - The Boston Globe: "In recent years, scientists have developed a novel theory of what falters in the depressed brain. Instead of seeing the disease as the result of a chemical imbalance, these researchers argue that the brain's cells are shrinking and dying. This theory has gained momentum in the past few months, with the publication of several high profile scientific papers. The effectiveness of Prozac, these scientists say, has little to do with the amount of serotonin in the brain. Rather, the drug works because it helps heal our neurons, allowing them to grow and thrive again."

http://blogs.intel.com/research/2008/06/unwelcome_advice.php: "The second path usually requires at least some degree of going back to the algorithmic drawing board and rethinking some of the core methods they implement. This also presents the “opportunity” for a major refactoring of their code base, including changes in languages, libraries, and engineering methodologies and conventions they’ve adhered to for (often) most of the their software’s existence."
