NTU scientists discover a way to produce cheaper, more powerful solar cells

This invention is well placed to power alot of applications :-
Eg.

(1) Replaced battery-powered car. With powerful solar-cell that can convert sunlight into more energy-efficient fuel for car - then no need to invest heavily in backend infrastructure to charge car.
The backend infrastructure that support the solar cell - is the Sun and is free. (有太阳神不用,用电池?)
Anyway this will be an important consideration for car producers to determine which way to go - to produce more battery-charged car or solar cell car.

(After note :- luckily we did not commit heavy investment into infrastructure to charge battery-powered car - otherwise we are doom.)

(2) Can power smartphones and tablets?

(3) Can power house electricity?

(4) Can power outdoor equipment that require energy like CCTV, traffic lights, street lamps etc.

(5) Can power signal sets?

NTU should patent this invention world-wide and not make the mistake the thumbdrive company did by patent it locally - and lost alot of money when the invention was copied freely worldwide without paying royalties.

Obama frustrated by snags in health-care rollout, says Treasury chief

The 14.6 million 1st 10 day of web hit to register the health-care rollout country-wide can be managed by computing the IT resources required (ie. how many web-hit transactions can one server handle, how many web-hit transactions can one server cluster handle - and once reach the limit will redirect to other Data Centres that have not exceed its limit to handle the transactions), the population distribution per region and allocate the web-hit to the respective Data Centres per region per server clusters via server load balancer within the Data Centres and using Global Load Balancer (via load balancing algorithm such as number of transactions, weighted, host dependant etc.) across Data Centres without causing overloading to any particular Data Centres.

Arab League chief says Syria peace talks set for Nov 23

I think there should be a political will to baseline a political settlement that will end the civil war.
As the time tick, more people are killed - including many unarmed civilians, and millions of refugees are suffering each day.

Lessons should be learnt from Iraq, Egypt - whereby if political settlement is not a win-win one - will cause the civil war to erupt again.

A win-win solution - could mean compromise on both sides. And this could be translated that both sides win something and not everything.

Lose-lose solution - is one that both sides lose - both sides win nothing and lose everything.

Second Japanese minister visits controversial war shrine

The more people are unhappy and concerned with the visit, the more people will do it, publicised it.

Because by doing so, it will score political points with virtually not much political cost - but serve the purpose of antagonism.

If no one response or irked by such visits, then no dust will be stir up - and soon it will no longer be news anymore.

别人气我, 我不气。
不然自己憋了一肚子气,气坏了是自己, 不是更自讨没趣?

Well maybe if people still cannot get over it, every visit is celebrated with holding 2 "Mushroom Feast Celebration" by the other sides - then both sides get even up. (Can smoothen the breath - at the same time can feed the stomach with 2 mushroom feasts - lunch & dinner).

If not the other sides can visit their war dead memorial and worship them with "Mushroom" offerings.


The both sides can get a good laugh (you tickle me, I tickle you) ....................

Palestinian president Abbas invites pope to Middle East

As reported :-

"Pope Francis gave him a decorative pen with which Mr Abbas said he hoped to sign a peace agreement with Israel.
"Soon, soon," the pope responded."

If the Peace Agreement between Palestine and Israel can be signed - it will be the "Mother of All Peace" in the Middle East.

Thousands of years of differences, animosity, bloodshed and hatred - can be forgotten and forgiven - and replace them with Compassion and Panna Wisdom.

It can’t be done for so many years. But for this round, Peace is a real possibility if both sides seize it and never let it slips.

“Mission Impossible – is Possible, if the Heart is Willing”.

PAP Community Foundation's website hacked by 'The Messiah': report

For sensitive public website, some good design will help :-

(1) Server and Operating system hosting sensitive public web - should be hardened - whereby all sensitive files must be locked for readonly and not writable and unessential services are properly disable. This prevent malware from infiltrating and attempt to alter system files, change registry parameters and settings, steal information, change password, take control of servers, alter web page without authorisation etc.

(2) Servers are connected through 2 sources - inband (that are public facing) - read only and not writable or very limited write access for eTransaction only. Out-of-band (OOB) - that are only accessable by Administrator with full access right. OOB is internal for server and web management - and not accessible by the public. Public - can only access via inband connection with limited or no write access - that why cannot deface the web page.

Alteration of web pages and services can only by done through OOB and not in-band.
(Note:- Inband and OOB are not routable to one another.)

(3) Use jump server or internal dedicated station to do updating of web services or perform admin function to the servers. Remote administration are disallowed and will be revoked. Thus no way for hackers to hack.

(4) Introduction of 2-factors authentication - even if hackers are able to steal the admin id and password, it still will not be able to access the server and web services to do damaged because another factor of authentication is required.

(5) Make use of directory services with another machines issuing digital certificate to authorise access. Hackers even though can hacked into the directory services with admin right will not have the right digital certificate as it is issued by another machine acting as Certificate Authority.

(6) Use CSP - Critical System Protection - to detect unauthorised hacking, do protection of all server files, detect malware infiltration, do intrusion detection and prevention, prevent web defacement etc.

Hackers who are able to deface a web page in 9 minutes means hackers is able to break and access the server with root admin password (unless the server did not change the factory default admin password) - taking full control of the server in minutes.

Hackers is also able to break the web page admin password - usually no default admin - which means this hackers is very skillful - could be using hacking tools that crack password.
(Oops sorry, with full admin right to the server, hackers will just replace the original web page with his own defaced web page - no need to crack the web page admin password. Think to deep and give the hackers too much respect.)


(After note :-

Of course doing all will be costly - which is meant for eCommerce.

With limited budget, doing some of those mention above - without the use of CSP will be very cost effective - and good to prevent or mitigate what the hackers can do.)
