赣州治疗狐臭多少钱赣州整形美容医院去晒斑怎么样One day, the father lets eight year-old son send a letter, the son took the letter , the father then remembered didn’t write the address and addressee‘s name on the envelope.有一天,父亲让八岁的儿子去寄一封信,儿子已经拿着信跑了,父亲才想起信封上没写地址和收信人的名字。After the son comes back, the father asks him: “You have thrown the letter in the mail box?”儿子回来后,父亲问他:“你把信丢进邮筒了吗?”“Certainly”http://mag.e-say.com.cn/wp-content/uploads/2013/10/笑话2.jpg“当然”“You have not seen on the envelope not to write the address and the addressee name?”“你没看见信封上没有写地址和收信人名字吗?”“I certainly saw nothing written on the envelope.”“我当然看见信封上什么也没写”“Then why you didn’t take it back?”“那你为什么不拿回来呢?”“I also thought that you do not write the address and the addressee, is for does not want to let me know that you do send the letter to who!”“我还以为你不写地址和收信人,是为了不想让我知道你把信寄给谁呢!” /201311/262931赣州俪人整形吸脂手术多少钱 First there was a website that predicted when your parents would die; now there#39;s a watch that not only predicts when you will die, it also begins counting down.先是出现了一个能预测你双亲何时去世的网站;现在有一种手表,不仅能预测你将何时去世,而且开始了死亡倒计时。Users fill out a questionnaire about their medical history before subtracting their age from the overall results to get their death score. This score is entered into the Tikker and the countdown begins.使用者首先要填写一张疾病史的调查问卷,然后根据问卷的综合结果减去他们的现有年龄,就得到了他们的死亡倒计时数字。这一数字被输入到手表Tikker中,倒计时就开始了。Dubbed the #39;death watch#39;, Tikker has been created by Swedish inventor Fredrik Colting but far from being morbid, Colting calls it #39;The Happiness Watch#39; and claims it has been designed to help people make the most of their life and cherish the time they have left.Tikker又被称为“死亡手表”,是瑞士发明家弗里德里克·科尔廷发明的。科尔廷绝非出于病态的意图,他把这款手表称为“幸福手表”,并称他的设计意图是帮助人们更好的实现生活价值,珍惜所剩下的光阴。#39;Imagine someone told you that you only had one year left to live. How would that change your life? For all of us life comes with a best-before date,#39; said Colting.“想象一下如果有人告诉你,你的生命只剩下一年时间,你的生活会发生什么变化?对于我们所有人来说,生命都是一次前所未有的约会。” 科尔廷这样表示。#39;While death is non-negotiable, life isn’t. All we have to do is learn how to cherish the time and the life that we have been given; seize the day and follow our hearts.#39;“虽然死亡是不可避免的,生活方式却是可以选择的。我们所必须做的就是学习如何珍惜时间和我们被赐予的生命。把握今天,随心而行。”Colting came up with the idea when his grandfather passed away. To set up Tikker, the wearer fills out a questionnaire by entering information about their medical history.科尔廷是在祖父去世时产生了发明此物的念头。佩戴Tikker的人只需填写一份关于疾病史信息的调查问卷,就可以启动手表。They are also asked whether they drink or smoke and if there are any instances of cancer, diabetes and other diseases in their family.问卷还会问及佩戴者是否酗酒,抽烟,有无癌症,糖尿病等家族病史。We arers are additionally asked about how much exercise they do, as well as how much they weigh before receiving a score.同时佩戴者们还会被问及他们是否锻炼身体,在得出死亡倒计时数字之前体重多少。Their age is then deducted from the results to predict a death date, and the Tikker begins the countdown.然后从结果中减去他们现有的年龄,Tikker就开始倒计时了。 /201408/317566大吉山矿区医院修眉手术多少钱

赣州隆胸医院I don’t think I’m spoiling too many surprises when I reveal that the plot of the film Gravity, a low-orbit spectacular starring Sandra Bullock and George Clooney, involves spacecraft getting hit by space debris. It’s a less fanciful premise than it might seem: in 2009, two unmanned satellites hit each other without warning, nearly 800km above Siberia.关于桑德拉?布洛克(Sandra Bullock)和乔治?克鲁尼(George Clooney)主演的、以近地轨道和壮观的太空为背景的电影《地心引力》(Gravity),我透露一下该片情节与太空垃圾撞击太空船有关,想必不算严重剧透。不过,电影的故事背景并不像看上去那样不可思议——2009年,两个无人卫星就在毫无预警的情况下,在西伯利亚上空近800公里处相撞了。That collision heralded a serious problem, first flagged in 1978 by Donald Kessler, then an astrophysicist at Nasa. The concern isn’t that space debris will rain down on us here on Earth: it’s that it will stay up there in space.那次碰撞事故预示出一个严重问题。1978年,美国国家航空航天局(Nasa)的天体物理学家唐纳德?凯斯勒(Donald Kessler)第一次将这个问题带入了世人的视野。令人担心的不是太空碎片会砸到地球上,而是这些碎片会一直留在太空中。The two satellites that collided, Cosmos-2251 and Iridium-33, weighed almost a ton and a half altogether. The result was at least a thousand fist-sized chunks of metal, any one of which could destroy a further satellite, and produce hundreds of further chunks. It takes time for these chunks to fall out of orbit.这两颗相撞的卫星分别是Cosmos-2251和Iridium-33,总重近1.5吨。碰撞后留下了至少1000个拳头大小的金属块,其中任何一块都能再毁掉一颗卫星,并产生成百上千个新的碎块。这些碎块要过很长时间才会从轨道上掉下来。What worried Kessler – and still does – was the prospect of a chain reaction. Too much debris in orbit would make it impossible to launch the satellites that have become an indispensable part of life back on Earth.凯斯勒当时担心的问题(这个问题现在仍然存在)是,太空垃圾可能造成连锁反应。太空轨道上碎片过多可能让人类无法发射新的卫星,而卫星已成为地球上人类生活不可或缺的部分。Nasa is tracking 21,000 pieces of junk 10cm across or bigger – like small cannonballs. In low Earth orbits, they are travelling at about 7km a second (25,200km/h). But space hasn’t been made impassable by debris just yet. There’s quite a lot of room up there, after all. Low Earth orbits are common but include a variety of altitudes, so objects have plenty of ways to fail to hit each other. Geosynchronous orbits, popular with communications satellites, must be exactly 42,164km from the centre of the Earth. But satellites that far out share more than 22bn sq km of space.Nasa正在跟踪2.1万个直径10厘米或更大一点的太空垃圾,这些太空垃圾就像一个个小炮弹。在近地轨道,这些碎片的飞行速度大约为每秒7公里(合每小时25200公里)。不过,太空碎片还没有多到堵塞太空的地步。毕竟,太空的空间很大。近地轨道比较常见,不过近地轨道的海拔高度各不相同,因此人造天体避免相撞的几率很大。而通讯卫星常用的地球同步轨道,距地心高度必须正好是42164公里。不过,在这个距离的轨道上,卫星可使用的太空空域总面积超过了220亿平方公里。Still, some orbits are more crowded than others; more collisions are surely just a matter of time. That was the opinion of a 2011 report from the National Academy of Sciences, “Limiting Future Collision Risk to Spacecraft”, which argued that there is aly enough junk crashing into other junk that the problem will worsen even if there are no further launches.不过,有的轨道仍更为拥挤一些,发生更多碰撞事件肯定只是个时间问题。2011年,美国国家科学院(National Academy of Sciences)发表的报告《限制飞船未来相撞风险》(Limiting Future Collision Risk to Spacecraft)就持这种观点。这份报告声称,太空垃圾相互碰撞的例子已经够多,就算人类现在停止发射新的卫星,这个问题也会不断恶化。Deliberately moving the debris somewhere safer seems possible, but pricey. It’s expensive to tidy up a satellite – or to design one that tidies itself up – and while the benefits of doing so are widely shared, the costs are not. So the clean-up doesn’t happen.主动将这些碎片移至安全地带看上去似乎可行,不过代价高昂。清理一颗卫星(或设计能自行清理的卫星)成本巨大,尽管这么做对大家都有好处,但这样做的成本却不会由所有人分摊。因此,“大扫除”方案是行不通的。The regulation of satellites is no simple matter: Cosmos-2251 was launched by the Russian military; Iridium-33 by a US corporation. The single largest space-junk incident was in 2007, when the Chinese military blew up a satellite just to show that it could. The regulatory authority capable of dictating to all three of those parties does not exist. (The ed Nations did issue voluntary guidelines in 2010.)对发射卫星进行监管可不是简单的事,Cosmos-2251卫星是俄罗斯军方发射的,而Iridium-33卫星则是一家美国公司发射的。而最大的一起太空垃圾事件发生在2007年,当时中国军方炸掉了一颗卫星,只是为了展示中国有能力这么做。目前,能令以上三个国家全都俯首帖耳的监管机构还不存在。(不过,2010年联合国(UN)确实发布过一套由各国自愿遵守的准则。)Economists such as Molly Macauley of Resources for the Future, a think-tank, have been pondering this problem for some time. The obvious economic solution, recently revived by three researchers, Nodir Adilov, Peter Alexander and Brendan Cunningham, is a tax on new satellite launches. Macauley has proposed linking the level of this tax to the design of the satellite – safer designs would attract a lower charge. Another possibility is that satellite operators would put down a deposit, to be refunded once the obsolete satellite had been pushed into a safer orbit.来自智库“未来资源研究所”(Resources for the Future)的经济学家莫利?麦考利(Molly Macauley)曾对这问题进行过一段时间的思考。经济学上有一个显而易见的解决方案——对新发射卫星征税。该方案最近在三位研究人员——诺迪尔?阿迪洛夫(Nodir Adilov)、彼得?亚历山大(Peter Alexander)和布伦丹?坎宁安(Brendan Cunningham)——的努力下再次流行起来。对此,麦考利提议将卫星设计与征税多少挂钩,设计得更安全的卫星可以少收一点税。另外,还有一种可能是,卫星运营方付一笔押金,这笔押金在过期卫星被移至更安全轨道后返还。This is one of those all-too-common situations when it is easier for economists to announce the optimal policy than it is for politicians to implement it. As with climate change, there’s a burden to be shared here, a threat of uncertain magnitude, and plenty of opportunity for free riding.不过,经济学家宣布一种最优政策容易,政治家实现起来可就难了——这样的事可谓屡见不鲜。太空垃圾问题和气候变化问题类似:需要大家共担责任,面临的威胁大小难以预料,有许多“搭便车”的机会。Yet this is a far cheaper problem than climate change, with a smaller number of decision makers. It should be easier to reach an agreement on space junk than on greenhouse gases. Alas, that is a not a very encouraging comparison.不过,解决这个问题比解决气候变化问题便宜多了,参与决策者也少得多。比起温室气体问题,太空垃圾问题应更容易达成共识。唉,这样的对比可不算令人鼓舞。 /201311/265471寻乌县做双眼皮手术多少钱 赣州俪人医院整形美容中心好不好

赣州美白针价格The sixth scam of Christmas is the drive-by download路过式下载Sadly you do not have to agree to download software from a malicious site for it to happen. There are ways in which malware can be wheedled on to your machine just by visiting a site.We all roam randomly around the internet, especially when looking for presents, so it is hard to avoid such sites. However, try to watch for a trail that leads you into totally uncharted waters. It#39;s difficult, but think before you click.令人沮丧的是,即便你不同一个恶意网站下载软件,骗子也能得逞。路过式下载(drive-by download)是一个在未经你同意或你不知情的情况下自动下载到计算机上的程序。And, keep your virus checker and your browser up to date. Both increasingly afford some protection again this type of scam.这种情况很难避免,因此点击前一定要三思。此外,保持病毒检查程序和浏览器的更新也是一种有效的防护措施。The seventh scam of Christmas is the fake free wi-fi假的免费wi-fiFor those who do venture out you will doubtless take refuge at some point in somewhere like a coffee shop, and often it appears to have free wi-fi.Such wi-fi connections should be considered insecure, so you should not visit any site where you need to enter credentials, card details or the like.All of that might be visible to others who can monitor your insecure connection to the free wi-fi.这种wi-fi很可能会出现在咖啡厅等地方,这种连接是很不安全的。你输入的凭据、卡的信息等重要资料都会被骗子获悉。The eighth scam of Christmas is the wi-fi probewi-fi探测Something few realise is that when we connect our mobile phone to a wi-fi, it keeps a record of the connection.Thereafter if the device is not connected to a hotspot, it continues to send out requests to connect to all the previous networks to which it had linked.These can be and we are revealing all wi-fis we have previously joined.In effect, your movements can be tracked and often your home network will even reveal where you live just by the name you have given it.Don#39;t give scammers information they might use against you in some form of con.当我们把手机连接到wi-fi,就有了连接记录。以后手机如果没有连接到新的无线热点(Hotspot),它就会继续向此前连接过的网络发送请求。这些连接记录都是可以读取的,这就意味着可以追踪你的行动甚至是住址。The ninth scam of Christmas is a combination of the last two免费wi-fiamp;wi-fi探测If you keep your mobile wi-fi turned on there are methods whereby, as your mobile sends out a request to connect to a hotspot, a scammer can then pretend to be that very wi-fi. Your mobile is relieved to have found a connection it knows and so attempts to create a link, potentially giving away your wi-fi password.如果手机wi-fi是开着的,手机会向无线热点发送连接请求,这时候虚假的wi-fi就可以趁虚而入,“假装”自己就是你所要连接的那个wi-fi。Worse still, your mobile might think it has a secure connection and start to send other data that can be picked up by the scammer.这种情况下可能会泄露你的wi-fi密码。更糟糕的是,手机以为自己在安全网络中,它会传输一些数据,而这些数据又会被骗子截获。This and the two previous scams can all be stopped by simply turning off your wi-fi on your mobile#39;s settings when not on a hotspot you trust.所以如果身处一个无法信任的无线热点,请关闭手机的wi-fi设置。The 10th scam of Christmas is the insecure website不安全网站Whether intentional or not, some websites still ask you for your credit card details - and much other valuable personal data - without offering a secure connection.一些网站会要求你给出信用卡的详细信息和其他有价值的个人数据,却无法提供安全连接。Know how your browser tells you that you have a secure connection - look for the padlock symbol or change of coloured address bar or whatever it is.If you don#39;t have a secure connection don#39;t trust that site with your details.要确定连接是否安全,可以查看挂锁标识和地址栏颜色的改变。They either can#39;t be bothered, in which case they don#39;t deserve your custom, or they#39;re a fake.Even if it is a secure connection make sure you click on the padlock symbol or similar to check that the site is registered to who you think it is.如果认为连接不可靠,不要给出详细资料。即便连接是安全的,也要确保点开的网站就是你所要上的那个网站。The 11th scam of Christmas is the Man In The Middle (MiTM)中间人A Man in the Middle add-on may be watching over everything you are doing. There is no point in having a secure connection to your bank or shopping site if there is a piece of software sitting on your machine that can all of the data before it is secured for transmission.A particularly common MiTM scam is for a ;helper; application that has been installed to make your life easier when using your browser.This helper may be helping itself to anything you enter on the screen.The safest way to avoid this is to ensure that you have no ;add-ins; running.If you know how, you can try this by manually configuring your browser but there are tools available, often from the banks free of charge, to do this for you.如果你的电脑里有一个软件可以在安全传输前读取所有的数据,那么或者购物网站的安全连接就毫无意义了。常见的“中间人”(MiTM)骗局就会将一个“Helper”软件安装到电脑里,让你使用浏览器时更加简单。但是这个软件可以访问你输入的任何东西,为了避免它的干扰,最好确保没有“插件”运行。The 12th scam of Christmas is the nastiest of them all: the phone call来电不善It is worth being sceptical about whether the person calling you is who they say they are. You#39;re having trouble with that new laptop you bought as a present. You#39;ve just about got it running but you can#39;t quite figure out how to finish it off.All of a sudden the phone rings and a voice says: ;This Microsoft/Apple/Google/Dell/HP we see that you have managed to connect to the internet using one of our machines/software but look like you could do with some support. We#39;re here to help you. All we need is your username and password…;These scammers work on the principle that eventually they will find someone in exactly that position and upon receiving such a call the frustrated user is very likely not to question but rather welcome the caller.All this caller is trying to do is help themselves to your login details and steal valuable data from your machine.Sadly, there are more than 12 scams to watch out for, but be particularly aware of those scams that take advantage of the time of year.Context is everything to the successful scam. If it appears relevant, useful or personal it is much more likely to succeed.想象一下,你买了一台新的笔记本电脑,刚刚让它开始运行,但是无法上网。这时一个电话打进来,告诉你他们可以提供帮助,只要你提供用户名和密码。事实上,骗子是想获得你的登录信息,并从你的电脑中窃取有用数据。 /201312/270433 石城县保妥适多少钱崇义县激光去痘印多少钱
