Comment Re:Stenotype (Score 1) 307

I'm not sure anyone has come up with the optimal keyboard layout for typing English, which I interpret to be the least amount of effort to type the most common words.

I did a quick comparison of QWERTY, Dvorak and Colemak on the finger movements required to type the most common trigraphs in English, which are: THE, AND, THA, ENT, ION, TIO, FOR, NDE, HAS, NCE, TIS, OFT, MEN, ING, EDT, STH. I threw in STR since that one is a very common consonant cluster.

The result: on QWERTY, you have to reach off the home keys 39 times and use the same finger more than once in typing 7 of the trigraphs.

For Dvorak, it was 13 reaches off the home keys, and no repeat finger usage.

For Colemak, it was 12 reaches off the home row, and 2 trigraphs that required using a finger repeatedly.

I see the value in increasing alternating hand usage to increase speed, but there is also something to be gained from having common trigraphs clustered so you can hit them in a rolling motion with your index, middle, and ring fingers.

For example, S-D-F and F-D-S, J-K-L and L-K-J are quick to type on QWERTY but rarely appear in English. Those prime key locations should probably belong to S-T-R and I-O-N.

I'll see your Wells and raise you a Watts:

"Let me tell you what happens if this thing gets out," she said quietly. "First off, nothing. We outnumber it, you see. At first we swamp it through sheer numbers, the models predict all sorts of skirmishes and false starts. But eventually it gets a foothold. Then it outcompetes conventional decomposers and monopolizes our inorganic nutrient base. That cuts the whole trophic pyramid off at the ankles. You, and me, and the viruses and the giant sequoias all just fade away for want of nitrates or some stupid thing. And welcome to the Age of Behemoth."

Comment Re:Unreliable hardware (Score 1) 536

I'm not sure I agree that it's possible to develop defect-free software. All hardware is unreliable. Mean time between failure.

Just to clarify, "defect-free" doesn't mean the software will always run correctly under any conditions regardless of hardware state. It just means that *given* the integrity of the hardware, the software will not have any uncontrolled failure modes.

Zero Day Hole In Samsung Smart TVs Could Have TV Watching You 249

chicksdaddy writes with news of a remote exploit in Samsung Smart TVs, and a warning for those who got one with a built-in camera. From the article: "The company that made headlines in October for publicizing zero day holes in SCADA products now says it has uncovered a remotely exploitable security hole in Samsung Smart TVs. If left unpatched, the vulnerability could allow hackers to make off with owners' social media credentials and even to spy on those watching the TV using built-in video cameras and microphones. In an e-mail exchange with Security Ledger, the Malta-based firm said that the previously unknown ('zero day') hole affects Samsung Smart TVs running the latest version of the company's Linux-based firmware. It could give an attacker the ability to access any file available on the remote device, as well as external devices (such as USB drives) connected to the TV. And, in a Orwellian twist, the hole could be used to access cameras and microphones attached to the Smart TVs, giving remote attacker the ability to spy on those viewing a compromised set."

Brain Cells Made From Urine 116

Press2ToContinue writes "Scientists have found a relatively straightforward way to persuade the cells discarded in human urine to turn into valuable neurons. The technique, described online in a study in Nature Methods this week (abstract), does not involve embryonic stem cells. These come with serious drawbacks when transplanted, such as the risk of developing tumors. Instead, the method uses ordinary cells present in urine, and transforms them into neural progenitor cells — the precursors of brain cells. Researchers routinely reprogram cultured skin and blood cells into induced pluripotent stem cells, which can go on to form any cell in the body. But urine is a much more accessible source."

Exactly. That was my first thought on reading this: "If there's a better way, show us. Come up with a solution. What's stopping you?"

In reality it's not that obvious, or someone would have thought of it already. I would look at engineering practices and see how they handle failure modes. Sometimes it is better to let the thing break as long as you design it to do the least amount of harm when it does.

It's possible to develop defect-free software as long as all factors are under your control. E.g. a program that runs on unreliable hardware can never be made reliable.

Artificial Wombs In the Near Future? 367

New submitter DaemonDan writes "The first successful pregnancy by IVF was accomplished over 50 years ago, essentially creating a multi-billion dollar industry. Many scientists are trying to take it one step farther with a 100% test tube baby brought to term in an artificial womb. 'Cornell University's Dr. Hung-Ching Liu has engineered endometrial tissues by prompting cells to grow in an artificial uterus. When Liu introduced a mouse embryo into the lab-created uterine lining, "It successfully implanted and grew healthy," she said in this New Atlantis Magazine article. Scientists predict the research could produce an animal womb by 2020, and a human model by early 2030s.' The author of the article seems to believe that birth via artificial wombs could become the new norm, but is it really feasible, desirable or even affordable for the majority of Earth's population?"
