How to lock Fn if you have one on your keyboard

How to lock Fn if you have one on your keyboard

You will notice a small padlock icon on the Esc key if that is the case for your keyboard. To lock the Fn key, simply press the Fn key and the Esc key together. Once the lock icon lights up, the Fn key has been successfully locked. To unlock, you can press both keys together again.

When it is locked, you don't have to press Fn together to get F5 or something else like that. Enjoy!

Scientists: Time to tweet

@chip_small

Time to tweet Nature (2011). doi:10.1038/nj7371-141a Author: Gaston Small Ecologist Gaston Small uses social media to talk about his work. Others, he says, must join him.

Social media can be used to predict social activity?! [Twitter]

This kind of research must be interesting! However, the conclusion may not so accurate because many people in some areas cannot access these media. Hence at the current stage of development, the first trial is going to be confined to Latin America. Sample is a problem!

In this kind of research, some institutes who control the knots to monitor the internet flow will have the definite advantage. Right now, I think the winner will be USA as they have the most IP control server (I do not know much about IT science, hope no problem here for understanding).

The Visual Impact of Gossip

流言蜚语造成的负面印象，要对人的视觉产生较长时间的影响（相对于中性和正面的印象）。这就不奇怪了，为什么现在媒体抓眼球的信息大多是八卦之类的负面信息。人原来生来就好这口！哈哈，想拒绝，那得淡定！

美国霸权的科技基础

最近随便查了一下SCI文章各个领域的情况，发现所统计的21个领域，美国发表的文章按照引用排名全部是第一。接下来的2，3名主要有德国，英国，日本，加拿大等。德国的实力也是很强大！

又查了一下两个顶级期刊中美国（USA），澳大利亚（Austrlia），中国（PR China)发表文章的情况，下面是数量和百分比。很能说明问题。纵然有politics在里面，还是能说明实力的！
Nature, USA(33489, 33.4890 %), Australia(1969, 1.9690 %), PR China(471, 0.4710 %);
Science, USA(45402, 45.4020 %), Australia(1069, 1.0690 %), PR China(497, 0.4970 %)；

Do not fool others on ebay!!! News from www.smh.com.au

eBay seller faces fines after bidding on own items to raise prices

MARTIN WAINWRIGHT

April 22, 2010

A British seller on eBay who drove up prices for his own goods by secretly bidding for them faces fines of up to £50,000 ($83,000).

Paul Barrett also used a second account on the internet auction site to post positive feedback. The company said the case, the first prosecution of its kind in Britain, was a clear warning against the practice of ''shill bidding'' to bump up prices.

powerpoint 输入中文问题

Powerpoint不能输入中文的原因：最近要用ppt 2007 做一个中文报告发现不能输入中文。换了几个输入法也不行。原来是关闭了输入法设置里的"高级文字服务"导致的。我在选项里一打开，PowerPoint就可以正常输入熟悉的方块字了

Human behaviour: Walking in circles

传说中的鬼打墙，最近有研究小组进行了研究，揭示了其中的原因。在光线较弱的情况下，比如黑夜，人倾向于转圈行走，不过半径比较大。如果完全蒙上眼睛，半径只有10m左右。表明人的行动要有参照物，不然就陷进去圈圈了。同样，如果在沙漠里面，只有很少的参照物，也是会迷失方向，造成恐怖的‘鬼打墙’。很有意思的研究。感兴趣的可以根据题目连接进入页面去查看详细信息。

Summary
Common belief has it that people who get lost in unfamiliar terrain often end up walking in circles. Although uncorroborated by empirical data, this belief has widely permeated popular culture. Here, we tested the ability of humans to walk on a straight course through unfamiliar terrain in two different environments: a large forest area and the Sahara desert. Walking trajectories of several hours were captured via global positioning system, showing that participants repeatedly walked in circles when they could not see the sun. Conversely, when the sun was visible, participants sometimes veered from a straight course but did not walk in circles. We tested various explanations for this walking behavior by assessing the ability of people to maintain a fixed course while blindfolded. Under these conditions, participants walked in often surprisingly small circles (diameter < 20 m), though rarely in a systematic direction. These results rule out a general explanation in terms of biomechanical asymmetries or other general biases [1,2,3,4,5,6]. Instead, theysuggest that veering from a straight course is the result of accumulating noise in the sensorimotor system, which, without an external directional reference to recalibrate the subjective straight ahead, may cause people to walk in circles.
