请不要责备英国医院或者NHS没有提前预备抗疫物资


英国的医院不收费,也没有收费处,材料应该都是系统依靠供应链配送,医院是没有用于采购医疗材料的自由资金的。

而且采购流程等都比较规范,按部就班的进行。要提前战略性备货,必须跳过很多流程和法律,只有在国家宣布紧急状态才可以。而国家卫生紧急状态还必须是WHO宣布灾害到一定的级别或者本国灾害到一定程度才可以宣布。这是先有鸡蛋还是先有鸡的问题,很多国家都是这样。我想这可能是很多欧洲国家和美国等发达国家缺少抗疫物资的系统原因。

从这一点来看,WHO迟迟没有参与调查疫情,没有宣布疫情全世界爆发是很多信赖WHO的国家损失惨重的原因之一。

Everything we do after a pandemic will seem inadequate



"Everything we do before a pandemic will seem alarmist. Everything we do after a pandemic will seem inadequate. This is the dilemma we face, but it should not stop us from doing what we can to prepare. We need to reach out to everyone with words that inform, but not inflame. We need to encourage everyone to prepare, but not panic." — Michael O. Leavitt, 2007

A Letter from Italy Warning for Coronavirus


I am writing to you from Bergamo, Italy, at the heart of the coronavirus crisis. The news media in the US has not captured the severity of what is happening here. I am writing this post because each of you, today, not the government, not the school district, not the mayor, each individual citizen has the chance, today to take actions that will deter the Italian situation from becoming your own country’s reality.  The only way to stop this virus is to limit contagion. And the only way to limit contagion is for millions of people to change their behavior today. 

If you are in Europe or the US you are weeks away from where we are today in Italy.

I can hear you now. “It’s just a flu. It only affects old people with preconditions”

There are 2 reasons why Coronavirus has brought Italy to it’s knees. First it is a flu is devastating when people get really sick they need weeks of ICU – and, second, because of how fast and effectively it spreads. There is 2 week incubation period and many who have it never show symptoms.  

When Prime Minister Conte announced last night that the entire country, 60 million people, would go on lock down, the line that struck me most was “there is no more time.” Because to be clear, this national lock down, is a hail mary. What he means is that if the numbers of contagion do not start to go down, the system, Italy, will collapse. 

Why? Today the ICUs in Lombardy are at capacity – more than capacity. They have begun to put ICU units in the hallways. If the numbers do not go down, the growth rate of contagion tells us that there will be thousands of people who in a matter of a week? two weeks? who will need care. What will happen when there are 100, or a 1000 people who need the hospital and only a few ICU places left? 

On Monday a doctor wrote in the paper that they have begun to have to decide who lives and who dies when the patients show up in the emergency room, like what is done in war. This will only get worse. 

There are a finite number of drs, nurses, medical staff and they are getting the virus. They have also been working non-stop, non-stop for days and days. What happens when the drs, nurses and medical staff are simply not able to care for the patients, when they are not there?

And finally for those who say that this is just something that happens to old people, starting yesterday the hospitals are reporting that younger and younger patients – 40, 45, 18, are coming in for treatment. 

You have a chance to make a difference and stop the spread in your country. Push for the entire office to work at home today, cancel birthday parties, and other gatherings, stay home as much as you can. If you have a fever, any fever, stay home. Push for school closures, now. Anything you can do to stop the spread, because it is spreading in your communities – there is a two week incubation period – and if you do these things now you can buy your medical system time. 

And for those who say it is not possible to close the schools, and do all these other things, locking down Italy was beyond anyone’s imagination a week ago. 

Soon you will not have a choice, so do what you can now. 

Please share.

Actions for UK government to stop the Corona Virus

As a tax payer, I am requesting the UK government to declare country emergency and :
1, Ask everyone to work from home if possible
2, Ask everyone to avoid public transportation if possible
3, Ask everyone to shop online if possible
4, Ask everyone to avoid indoor places where lots of people gathering, such as cinema, shopping mall
5, Close all schools
6, setup check point to screen temperature at airport for all passengers
7, Close the board or isolate for 14 days for people from oversea
8, Declare country emergency
9, setup check point to screen temperature at train stations for some areas
10, Ask everyone to keep one metre distance when queuing, talking etc.
11, Ask public facing staff (such as waitress, shop keeper etc.) to wear face mask


Each those measures may only contribute 1% or less on stopping the outbreak, but all added together will save thousands lifes in UK or may stop the breakout.

HP ProBook overheating and cursor jumping

I have a 2014 HP ProBook 450 G1 15.6-inch (Intel Core i7 2.2GHz, 8GB RAM, 750GB HDD, Windows 7 Professional). The temperature of CPU rise very quickly up to 100 degree and the mouse cursor is jumping towards the edge of the screen about once every second.

This issue has been for about two years. The laptop was very expensive and I do expect it to last longer.

-----------------------------------------
Update on 4/Jan/2010: After uninstall and delete the touchpad drive a few times, and then install the Synaptics driver 17.0.18.8 seems solved the overheat issue. The touchpad is still disabled as I always use external mous, but the cursor still jumping.

I won the court case against Churchill Home Insurance

People may recall that my house was damaged by the storm on Feb/2018. Churchill Home Insurance refused my claim, so I took the Churchill Insurance to the court.

Churchill Home Insurance refused to discuss for a settlement and insisted to go to the hearing.

Fortunately, I finally won the case on the hearing at the Cambridge County Court by myself (I don't appoint any solicitors).

Despite I won the case, I don't suggest others to take the similar action without solicitors. It was so stressfull, just not worth the time and effort.

Huawei is really in trouble without ARM licenses

Huawei is in really trouble with business stopped by ARM.

A mobile phone chip usually has many CPUs apart from the 4 or more main cores which are well known by most of consumers. It wouldn't surprise me if there are more than 10 small CPUs such as ARM M0, M3 of M4 inside.

Without licenses from ARM for those small cores, I expected Huawei is no more able to make the Kiren chip legally.

Let's wait and see.

Boeing Issue is System Failure of Management

The Boeing problem is not a single technical issue, it is a system failure of the management including specifying, design, verification, validation, quality control and certifying.

Looking backwards, there are some obvious flaw of the MCAS system on the very early specifying stage, and none of the later management process including FAA checking caught the problem.

If those management system issues cannot be addressed by Boeing, then I expect more and more issues will be discovered, some may more serious than the MCAS system flaw.

Boeing is still trying to limit the issue in technical level which is the most dangerous thing.

Not sure what is causing the issue, it might be the HDD or FreeNas 11.


Setting:
Lenovo TS104  + ESXi 5.5
SAMSUNG 2TB
WD RED 4TB
FreeNAS 11 on ESXi


-----------------------------
update on 21/Oct/2018:
It might be caused by the use model combined with FreeNas and HDD. I was created 6 ESXi 500GB HDD files which made a 3TB striped volume in FreeNAS. It is likely FreeNAS considers that all 6 HDDs are independent and wait for the responses of the "sync write access" from all the 6 HDDs. Since the 6 HDDs are actually from a single physical HDD, so it is possible causes too much load for a single HDD and results HDD hung.

I am now testing a single ESXi 3TB HDD file to make the volume in FreeNAS, it has been running for a few days and so far looks good.

Churchill Home Insurance is a Joke

The roof of house was damaged by the storm at night of 2/January. Churchill Home Insurance declined my claim. Churchill Home Insurance said it is because is not properly maintenanced and there's no storm reported despite storm news reported on various news.

关于虐童现象


女儿在约5岁时(约8年前)回国探亲,到国内当地一很有名的幼儿园体验生活。因为没有习惯午睡,被看护的阿姨(老师)恐吓说要扔出窗外,至今她记忆犹新。看护阿姨知道她是国外小孩,只是体验几天。女儿当时也不敢告诉大人,最近几年她长大慢慢懂事了才告诉大人。

这里并没有责备看护阿姨的意思,只是想说除了体罚,还有精神上的惩罚。另外大部分家长自己(包括受过高等教育的我)也会对小孩体罚和精神惩罚。

这些并不是某特定人的过错,也许需要官方教育牵头下至少一代人的努力;如果没有官方教育牵头,只是任凭社会自己纠正,一代人也许远远不够。等到家长不会对自己小孩进行体罚(惩罚)的那一天,这些现象才可能会慢慢减少。

呼吁大家能够用自己的影响力,从身边做起,争取让这种现象慢慢减少。

Everspring SA413 Z-Wave USB Stick with Openhab2

I just made Eversprint SA413 Z-Wave USB stick working with Openhab2, no special driver or special configuration is needed, it just working. This stick is bloody cheap, it only cost me £5.99 from the ebay.

Also the Heima Z Wave Door/Window Sensor (HS1DS) working fine with SA413 in Openhab2.

Configuration and pair can be done via the Habmin.



Here is a small user manual for HS1DS ZWAVE door sensor:

  1) Slide the back to one end to remove the back.
  2) Press the small switch a few (some people say 3) times, light on front will blink green indicate pair mode
  3) Hold the switch while install the battery will do factory reset which will erase setting. (Not checked, forgot where I read this)

美国教授写给被开除中国留学生的信:做人 做学问(转)

  本文作者是一位来自美国的哲学教授。她现在是美国C大的终身教授,曾任美国哲学协会“亚洲哲学和亚洲哲学家委员会”委员。近年来,她在海内外发表大量散文、诗歌、小说及哲学论文,作品曾获“联合文学奖新人奖”等多种奖项。

  作者所在大学开除了一位来自中国的研究生,而作者本人正是这位研究生的导师。从这一事件中,作者观察到中美大学教育的差别,同时郑重地给这位被开除的留学生写了一封信,坦诚地表达了她本人的观点。从中,我们看到了作者诲人不倦的谆谆教导之心。这也给广大已经或即将赴海外留学的中国学生提供一个重要的参考,同时对于中国大学教育以及想送孩子出国留学的家长也有一定的借鉴意义。

  开除一个研究生,在任何大学都不是一件小事。各个大学可能标准会不同,但都有严格、严肃的程序,且会给学生预先警告和上诉机会。以文中的C大为例,该校的研究生院在学生得到第一个坏成绩时,就送一封警告信给他,同时告知项目导师。如果某研究生得到三个C,那一定要开除。除非学生有充足理由,向研究生院董事会上诉,说明他有特殊原因,才得了坏成绩。因为,C大研究生院规定,学生平均分数必须达到3.0 (平均成绩为B)才能毕业。研究生毕业,一般要36个学分左右,得了三个C 后,学生基本没有可能再把平均成绩拉成B了(文中的这个学生得到第一封警告信时并不在乎。得到第二封时,有一点害怕,但还顽固地认为:他能把教授哄住,摆平。他就是做了这样的错误假定)。研究生院董事由各学院20多位教授组成,就算导师不支持学生上诉(导师认为学生不可能把成绩拉上来了),学生依然可以上诉,20多个教授要看学生获得等级分C的课的作业和成绩,再根据学生上诉理由、导师评价,最后投票决定是让学生回到项目里继续学业,还是开除。如果研究生院董事会投票结果是开除,基本就是定局。虽然学生还可以再向教务长上诉,但那个上诉就是反对20多位董事的决定,学生基本没有可能成功。美国大学宽进严出,学费又高,就是进了研究生项目,学生都好好学习,谁也不敢假定学位就稳稳到手了。

  XX同学:

  接到你要求“保留学籍”的上诉被研究生院董事会驳回的消息,我想告诉你:这是你的失败,也是我的失败。你很难过,我也很难过。一个教授,一辈子培养不了多少研究生。你祟拜的Y教授,刚去世,他一辈子也就培养了九个“东西方比较哲学”的研究生。我创建的C大“东西方比较研究”,从第一个研究生到最后一个研究生,一共十一个。你是第十一个。现在,第十一没有了。因为项目停了,以后也不会再有。在美国,或在C 大,遍地都是西方文化,加开一点中国文化研究项目,很不容易,全是教授自愿作出的无偿贡献。所有的研究生,都是教授的作品。我用同一个标准要求所有的研究生,我希望每一个作品都是杰出作品。你被取消学籍,第十一个作品报废。你没达到标准,是我和你的共同失败。

  你想到的是:你的前途中断了。这是不对的。你的前途依然有无限多的选择。你可以从商,在网上办你的杂文网站,或回中国办公司,再换一个能收你的项目学习,等等。我希望你在别的行业和地方能有成就。如果,你下了决心要在学术界做学问,我下面写的东西,是给你的临别礼物。如果你不想做学问了,下面的话,你根本不用看。世界上路很多,不一定要做学问,做个好人,就值了人生。你可以就看到这句为止:“你当个好人,我祝你好运。”

  如果你往下看了,那我假设你想知道为什么你刚开始往“做学问”这条路上走,就失败了的原因。如果,你还想走做学问的路,下面的话会对你有用。我对你直话直说。

  事实上,我从来没有跟你绕过弯子,也没有改变过对你的要求。你失败的原因,有些是你自己的责任,有些是那些把你教成这种样子的教育模式和社会环境的责任,有些是我的责任。

  先讲我的责任。我的责任是:我不应该录取你。因为你想要的东西,我无法给你。

  你想要的是到美国来见识一圈,和教授搞好关系,使一些点子,让教授按着你的设计,给你一些作业,你轻轻松松得到一个学位;再靠这个学位,说自己成为学者了,然后在中国或美国找个挣钱多又体面的工作。你说你将来想在大学当教授,你还对我说过不止一次,你必须得到这个学位。我懂这个学位对你的重要性。

  但是,我能教给你的,是做人和做学问的基本原则,让你成为一个尊重知识、热爱真理的人。在学术领域,你必须不为任何利益撒谎,只说真话,且对自己说的每一句话负责任;你必须脚踏实地,一步一步去寻找未知,没有捷径可走;你还必须知道自己的局限和无知,把你个人的角度和判断低低地放在“公正”之下,这样,你才能开始做学问。要想从我这里得到学位,你必须达到这些标准,我不卖学位。我的知识可以无偿贡献给愿意跟着我一起寻找真理的学生,但不做交易。

  这是我们之间的误区。我是在你选了我的两门课之后,才认识到我们之间的这个误区。这个误区,造成我们之间的所有冲突。我认识到,把你录取来,是我犯的错误,也是对你犯的错误,让你错误地计划了前景。

  其次,讲你的责任。讲你的责任,其实是我对你的最后评价。或,是我给你的解释——为什么你不适合做学问。你可以成为一个很好的商人、公司老板或其他什么职业人士。搞学术,和经商或当清洁工,没有职业高下的不同,但明显有职业要求的不同。做学问,要有品格,最首要的是,得做人。我前面说的误区,与其说是学术上的,不如说是如何做人上的。你在C 大期间,做学问的技术,我时时刻刻在教你,那些技术都详细写在你的每一篇作业和论文上了。但是,关于做学问和做人的关系,我没跟你讲透彻。在谈你的责任时,我会讲这个问题。

  因为你本科成绩不好,我亲自在北京对你面试后,才决定录取你。录取你,是我拍的板。当时,我对你的判断是:人很聪敏。但是,那是一个错误判断,因为那个错误判断,我得分担你失败的责任。现在,我对你的评价是:你不聪敏,你没有一点儿做学问的人所必需的聪敏。这种聪敏就是苏格拉底说的“我知道我的无知”。

  你一进校的时候,就认为在美国上大学很容易,你知道怎么能玩得转。你不停地显出你什么都懂;参加讨论,不懂的事,你也常常不懂装懂,胡说一通。上课,你原着不读,必读书不买,看一些网上第三手的书评、简介,就敢宣称:书读完,懂了。就敢狂加评论。你有种种理由认为你是对的,所以,你可以轻而易举地宣称,你懂了,你比同学教授都懂得快。你有你的机巧。但你的读书“机巧”我完全不看好,那是做生意的机巧,不是做学问的技术。我对你的判断是,在我的前三门课上,我要求的必读书,你不是没读,就是没读懂。你真正开始认真读的一本书,是我的第四门课“比较逻辑”上的《逻辑》。这本书,目前,你读懂了60%。这是你的进步。

  我想告诉你:你这种很坏的学习方法,至少得为你的三个“C”和两个“I”,负一半责任。

  用你那种学习方法做不了学问。你可以东找一点西找一点猎奇的信息,放到你的网站上,让大众读着玩(这是你的权利),就像旧时茶馆里说书的、传小道消息的人,目的就是吸引听众兴趣一样。这没什么不好,也是一种传媒方式。但这种方式绝不能用来做学问。做学问,不是猎奇,也不是快速地搜罗信息。做学问,是一点一点地积累,在他人工作的基础上,拨开前面让人看不清楚的杂草,细细地分析;用理性拷问自己,拷问先人;然后,向前小心翼翼地放一块小小的新石头,让后人踩着,不摔下来。这就是为什么维特根斯坦将能不能把思维说清楚看作是一个道德问题。你很爱说,也总是在说。但是,你很少能把问题说清楚。在做学问上,“凡你能说的,你说清楚;凡你不能说清楚的,留给沉默。”(维特根斯坦,Tractatus)在一知半解的时候,你胡说,那叫“扩散无知”,是害人、误导,是浪费别人生命。做学问的人,要对自己说的每一句话负责任。如果你不能,或不想负这个责任,你别走这条路。我不培养产品推销商(不会),也不培养哗众取宠的网络编辑(没能力)。

  因为你学识基础很差,你得弥补这个致命缺陷,才能去做学问。学识基础差并不要紧,你从基础开始好好补,是能赶上去的。但是,你却用了一些奇怪的、与学者品格不相容的方法来掩饰你的致命弱点。第一个例子,你刚来的时候,和我谈话,动不动就扯出一些社会“名人”,这个,那个,你跟他们都认识。你说的这些“名人”,我半个也不认识,也不知道你为什么要把这些人的名字夹在你和我的谈话中。我也不想认识这些社会“名人”。如果他们有成就,我为他们高兴,但是,他们与你我都无关。你要做学问,好好跟我学,不必去追啥社会“名人”。学术不是社交,不是出名,是坐冷板凳。你做学问的目的,必须是对真理的热爱和对未知的好奇心。名不名与学者无关,得奖也是天上掉下来的馅饼。对学者来说,做学问本身,就是乐趣所在。想用社会“名人”来衬托你自己的地位,你要么是骗人,要么是骗自己,都是想掩饰你先天的不足,没有自信心。如果你不想用你自己的人格魅力赢得他人的信任,你也不能做学问。

  再一个例子,就是你在XXX课上的抄袭问题。你可以跟我解释,从网上复制了东西,贴下来当作业交给我,不叫“抄袭”,是我“误解”了。事实上,我也没真报告你抄袭。你也用不着解释来解释去,说你不是存心要抄袭,怪我不理解。我理解或是不理解,其实都不是关键。关键是:一,我没有报告这事件;二,不管我“误解”不“误解”,事实是你交来的作业,7%以上绝对与网上他人的东西一样,这就叫“抄袭”(按C大校规定义,7%以上雷同就叫“抄袭”)。这件事,是我坚决反对你想找捷径、借以掩盖你的基础差和没有治学能力的缺陷的开始。我就此警觉并反对你的走捷径,一直和你对抗到上周的最后一次考试。

  对你第一次“抄袭”这事本身,我只希望你说一句话:“对不起,我再不这样做了。”然而,我得到的却是一次又一次的报怨:为什么我不理解你的解释——那不是“抄袭”。我没有报告你抄袭,甚至都没有取消你的奖学金,这是我所能做到的对你的最大保护,是给你改正机会。但,你要我接受“那不是抄袭”,这是你在指鹿为马,还公然要求你的教授跟着你一起自己骗自己,真是滑天下之大稽。你可以赖掉一个错误,我可以不追究,但你同时也失掉了我对你的信任。如果,你还想做学问,你永远要有能力和勇气认识和承担自己的错误,不然,你不能做学问。

  你自己要承担的责任,还包括你的人格分裂。这一点,不能全怪你,人格分裂是畸形教育的结果,这也是我最后要讲的你的社会背景的责任。你是我见过的最自相矛盾的学生。当我想到你的社会背景,我对你的人格分裂抱有同情。但是,我还得指出,这是病态。你应该尽快找心理学家帮助,治好这个毛病。做学问的人,必须里外一致,言行一致。

Successfully installed Samsung 850 EVO SSD on samsung np530u3b

Just follow the steps below:

(from: http://superuser.com/questions/510311/trying-to-install-windows-7-on-samsung-530u3c-laptop-wont-boot )



First, some background. This laptop comes with a 1TB HDD and an 8GB iSSD, which is used as a cache to speed up Windows and apps. Samsung uses Diskeeper's ExpressCache software for that purpose. This SSD causes a rather large problem to the Windows installer. For whatever reason, Windows refuses to install its "System Reserved" partition on the HDD, downright refusing to proceed with the installation if the SSD is already partitioned for ExpressCache. But, repartioning the SSD and just letting Windows install itself, doesn't make things easier. In fact, it causes major troubles. It appears that the BIOS really doesn't want to boot off the SSD, which is where Windows decided to install its boot partition. So, here's the thing- how to get the HDD into a state where both Windows and Samsung's BIOS were happy, and the SSD free for ExpressCache use.

Before installing Windows and things to keep in mind

  1. For your convenience, you might need to print this guide and read once before proceeding.
  2. Backup your drivers to an External Flash Drive or DVD, using Samsung Recovery Solution. (Bear in mind that you don't have any network connection after a clean install and neither a backup partition at your pc)
  3. Make sure your BIOS are set to boot from DVD or USB Drive, by changing priority. If you choose to use a USB, you have to disable "Fast BIOS Boot" as well.
  4. In case of using a bootable USB for the installation, a message might emerge, implying that drivers are not installed and cannot proceed further. Just click "Cancel". Then, you will be brought back to the welcome screen. At that moment, remove the USB drive and plug it back in, to a different USB port this time. Click "Install Now" again. The installation should proceed as usual.

Installing Windows

  1. Insert the istallation media on your laptop.
  2. At the Windows Setup Wizard, select "Custom Install" to view all disks.
  3. At the "Advanced" option, choose to format all disks and delete the SSD.
  4. Press "Shift+F10" to launch cmd. Otherwise, reboot into the Windows Setup wizard and choose the "Repair" option, in the bottom left corner, and in the tools menu choose cmd.
  5. Type in diskpart to get into the partition tool.
  6. Use the commands list disk and list part to determine which disk is what (check size parameters). For me, Disk 0 was the HDD and Disk 1 was the SSD. The following instructions assume this.
  7. Select the HDD: sel disk 0
  8. Delete all partitions on it: clean
  9. Create a 100MB partition for Windows 7 (or 350MB for Windows 8): create part primary size=100 (or size=350)
  10. Format it: format fs=ntfs quick
  11. Assign it a letter: assign letter=f (if F: is in use, pick another one. Use the list vol command to see all volumes and their letters)
  12. Create a partition that fills the rest of the disk: create part primary
  13. Format the large partition: format fs=ntfs quick
  14. Assign it the letter C: assign letter=c
  15. Exit both Diskpart and cmd.
  16. Reboot back to Windows Setup Wizard to install Windows into the large partition that was just created. !!CAUTION!! When Windows restarts your machine to complete the installation, do NOT change priority at the BIOS menu as usual, but instead boot from the installation media, once more, and choose the "Custom Install" option.
  17. There is a great chance that Windows installed its System Reserved partition on the SSD, so choose the "Advanced" option and delete the SSD. Launch cmd (Shift+F10) and type diskpart.
  18. Use the commands list vol and assign to ensure that both the system (F:) and the boot partition (C:) still have drive letters.
  19. Select the system partition (sel vol f) and mark it as active: active
  20. Exit diskpart and at cmd type the command: bcdboot c:\windows /s f:
  21. Reboot and you're good to go.

After the installation

  1. The easiest way to have Samsung's Easy Settings and ExpressCache installed to your machine is through the backup created by Samsung Recovery Solution, since you don't have an internet connection after the clean install. (Even when you get to have one, do not connect during this proccess (because of Windows Update interference) and wait till it finishes)
    1. Browse the DVD or External USB Drive to find the "SystemSoftware" file and launch the "SecSWMgrGuide.exe".
    2. Install "Easy Software Manager".
    3. Install everything from the "Drivers" tab.
    4. From the "Miscellaneous" tab, install "Windows 7 SP1 Critical Updates" and "Windows 7 SP1 common patches".
    5. From the "Utility" tab, install "Easy Settings" and ExpressCache".
    6. Finally, choose any other software you might need.
    7. You are ready to connect the internet and install Windows Updates.
  2. In case you didn't backup your drivers using Samsung Recovery Solution, you need to manually download and install these drivers from the Samsung's website.
  3. To find out if ExpressCache is working, run cmd as administrator and type ECCmd -INFO. If it's marked as mounted and gives you the application's information then you're fine.
