AI found Mysterious fast radio bursts from deep space, ‘could be aliens’
The origin of fast radio bursts (FRBs), millisecond-long pulses of radio waves, may be generated by black holes or super-dense neutron stars merging together. However, for such astrophysical phenomena events randomly repeated at the same location twice has a tiny chance.

First Commercial Quantum Computing System from IBM
The system can be used to predict events that are almost impossible for classical computing, but which quantum computing is uniquely adept at solving. For example, predict financial events, optimize logistic problems.
𝑖ℏ∂Ψ(𝑞,𝑡)∂𝑡=HΨ(𝑞,𝑡)
Quantum mechanics describe our world as entangled waves in time and space (or a set of vectors where time and space dimensions are just mathematical presentations), instead of collection of small particles moving in space. This means that, because of this property of measurement in quantum mechanics, our universe is inherently a non-local, and everything seems connected. In another word, any quantum mechanics interaction has the whole universe considered, that's why it is simpler to predict financial events for quantum mechanics -- complexity and considering the influence of outside world is not a problem at all in quantum mechanics!
Here is an example program I ran on a 3 qubits IBM Q quantum computer. It demonstrate the quantum entanglement.
qreg q[2];
creg c[2];
cx q[0],q[1];
measure q[0] -> c[0];
measure q[1] -> c[1];

13473227341 or 3473227341 is a phishing phone number
Searching for 13473227341 yield a Chinese city as origin; after removing the country code 1, searching 3473227341 shows it is a New York phone number.
This kind of robotic phishing phone calls are trying to collect legitimate phone numbers or even personal informations.
The best action is not to give any response and look up for the phone number to tell if it is really belong to a business.
7183180198 is a phishing phone number
This number is not a real number, but from phishing software. It is trying to collect phone numbers if you pressed 1.

My bad experience on fedora 10 network bug

I wish I knew fedora 10 have a network bug for static ip configuration, but I didn't!
I went through the normal steps.
Check OS information with "uname -a" and "dmesg head -1".
Check network information with "ifconfig", "/sbin/route -n" and a few ping and traceroute.
Ask my friend for the default gateway and the previous ip address (it's better to use the previous ip to save us from nasty kinks).
Educate my friend about the Linux desktop, where to find the GUI to fill in the ip address and default gateway.
Ahaaaa, here's the catch! She kept complaining that linux automatically changes netmask to gateway...
So, I decided to go the sure way --
Ask her to add default gateway into
/etc/sysconfig/network
/etc/sysconfig/network-scripts/ifcfg-eth0
And restart the network service by typing "service network restart"
She still complained that linux automatically changes netmask to gateway...
I got confused, but make another try -- "route add default gw xxx.xxx.xxx.xxx eth0" -- and got more confused after getting "siocaddrt no such process".
Now it's my time to panic...
After googling for a while, this post finally explained everything:
"Unfortunately, to date (8th/Dec/2008) there is a bug with system-config-network (GUI Version) in which it incorrectly stores the network mask as the default gateway address."
"Fedora 10 disables the "network" service in preference to using "NetworkManager", therefore NetworkManager will need to be disabled before enabling and configuring the network service."
Now I'm happy my friend's firefox can link to pages.

Yahoo! 360° is closing today
"Make sure to save or download your existing content before July 13, 2009. On this date, all remaining material on Yahoo! 360° will no longer be accessible."
Yahoo! 360° has many nice blog feature to it, easy to use and give user a social networking site running by Yahoo!. As many users noticed long time ago, Yahoo! 360° gets slower and slower, besides, the social aspect of Yahoo! 360° turned out not so successful, there are plenty of other social networking sites which just fulfill a different function.
I think many users will move to blogger or blogspot after the closing.

Blog on WordPress got suspended
This blog has been archived or suspended for a violation of our Terms of Service.
The above scaring image is what I saw when visiting my blog at wordpress tonight.
I wonder what happened to my blog?
As I google "This blog has been archived or suspended for a violation of our Terms of Service. wordpress". I realized many people got automatically banned by their Spam-Filter. Wordpress's current Spam-Filter technology using words or links alone to detect the untrustworthy content, which isn’t context-aware. They may ban ppl for a bad link in the post or ban ppl because of taking others content.
I guess a post copied from a blog caused the trouble, but I I DO put a link to the source at the first line of my post as source article! Anyway, I should receive an email from their supporting group soon.
By the way, complaining on the WordPress.com Forums is not an option now, because the supporting group became clever after dealing with numerous similar cases.
You've been blocked. If you think a mistake has been made, contact this site's administrator.

Bing continue to gain market share
Microsoft Corp.'s new Bing search engine was available two weeks ago, with a $100 million marketing campain.Just in two weeks, Microsoft's share of search results pages -- a measure of the intensity of search activity by online users -- rose to 12.1% between June 8 and June 12.
It is unclear, if bing will shake the dominate position of Google and Yahoo which have U.S. market share around 60% and 20% respectively.
Compared with Google, bing has a more attractive user interface, and optimized for searching on shopping, travel, health and local businesses. Rumors said, Larry Page had teamed up his top experts to analyze the bing's algorithms. The war is coming? Let's see.

Obama Sees 10% Unemployment Rate

President: “Yes,”
Hunt: Before the end of this year?
President: “Yes,”
President: “I think that what you’ve seen is that the pace of job loss has slowed and I think that the economy is going to turn around. But as you know, jobs are a lagging indicator. And we've got to produce 150,000 jobs every month just to keep pace. we will end up seeing recovery shortly.”
Biggest Health Care Reform in US history is coming

June 17 (Bloomberg) -- The largest expansion of U.S. health care since the creation of Medicare in 1965 may emerge from legislation designed to reshape the medical industry and change how Americans receive and pay for care.
Congress today begins crafting legislation that Democratic leaders plan to push through both chambers by their August recess. The measure may require all Americans to get medical insurance, force insurers to accept all patients and end the tax break for employer-paid health benefits. These changes may be hammered out with unprecedented speed at the urging of President Barack Obama, who four days ago said “this is the moment.” The U.S. will spend more than $2 trillion this year on health care, the Health and Human Services department reported in February.
Obama has made a health-care overhaul his top domestic priority, using his February budget proposal to call it a “moral” imperative to extend coverage to the country’s 46 million uninsured. Obama also tied the long-term fiscal soundness of the U.S. to controlling medical costs. Health care consumes 18 percent of the U.S. economy and may rise to 34 percent by 2040, the White House Council of Economic Advisers reported June 2. The coming weeks will be pivotal if the House and Senate are to meet their goal to send Obama a single bill in October. “The president wants a bill by Oct. 15,” Baucus said in an interview yesterday. “He’ll get it.”
One issue is taxing employer-provided health benefits, which Obama opposed during his presidential campaign. In an interview yesterday with Bloomberg News, Obama said he wouldn’t rule out such a proposal.
“I don’t want to predetermine the best way to do this,” he said. “I’ve already put forward what I think is the best way. Let me see what comes out of the Hill and we’ll have that debate then.”

Signs for economy recovery.

#1 Sales at U.S. retailers rose in May for the first time in three months as shoppers returned to automobile showrooms seeking bargains from the ailing carmakers.
#2 Crude oil rose for a third day, climbing above $72 a barrel for the first time in seven months as the International Energy Agency raised its demand forecast and China’s net imports jumped to a 14-month high.
#3 Fewer Americans filed claims for unemployment benefits last week, indicating the deepest job cuts may be subsiding even as companies hold off on hiring.
