Noam Sheffer

It is shocking to visit a dead Friend’s twitter page and see “I’m alive” in the profile.

A book by Kawakami Hiromi.

Trying to read but struggling, it is not about the language but I feel I am missing cultural knowledge.


Story managed to interest me and sweep me into a fantasy world, but I think there are some levels of complexity related to Buddhism which I don’t understand .

(Or maybe I am wrong and try to find meaning when there isn’t )


Amalie Emmy Noether

I love The Google Doodle. Especially when I study something new.


This time, it is about Amalie Emmy Noether , A mathematician which contributed to abstract Algebra theoretical physics.    Wikipedia mentions she was German and a Jew, but considering the fact she had to quit her university post due to the Nazi rules, I am not sure we can consider her German.

Inspiring story


On Religion, or is it hate/ignorance

Just received a comment on this blog, praising Hitler and stating that what ever he did was punishing the jews.

Is the writer Muslim?  I don’t know. I know he is using a comcast address in the Washington area.

Stating that 6 Million Jews were killed as punishment for a fictional story in one of the holy books makes me really sad.

(Rejected) Comment quote and screen capture below

He was dispensing the punishment that god had promised the jews for disrespecting him as seen in the quoran. Allah had promised to punish the jews for disreguarding his orders while moses went to get the 10 commandments



Hate comment


Receiving Earthquake and Tsunami warnings which are out of my region can be quite alarming.

Around 8:10AM started to receive Tsunami warnings on my cellular phone.

Tsunami ? Where? why ? – I didn’t notice any earthquake.

Checking further showed that there was an Earthquake off the coast of Iwate, which may cause a Tsunami.

Definitely worth the alerts, yet a bit disorienting.

The image shows the alerts which provided more information on location.


Machine learning – Weeks 1-2

Really enjoying writing Matlab/Octave code for the Machine learning course.

It has been a while since I used Matlab. Was it during a signal processing course, or was it at the Air Force?

Can’t post my code, but can definitely post the result of my calculations.

Hope I can blog about this…

This blog is active for more than 5 years. Actually, active intermittently.

What I noticed is that although the traffic to my blog is almost the same level as it used to be 5 years ago, less people click on ads.

I don’t rely on ads to run my website nor do I expect to earn money, but I do want to figure it out.

Is my placement bad?

Are the ads chosen by Adsense not effective to my audience? -> How do I check that ?

Is it that users block ads or just don’t click ?


I don’t block ads, but I don’t think I clicked on one in the last month.
