Nice, France

The third of Dad's galleries:



I recommend you raise the slideshow speed. Here's the link to the flickr page. 
Although I've been there, it was years ago, at a different time. Beautiful, ain't it?

Some Explanatory Videos on Exoskeletons


Here's some more info on Cyberdyne's HAL and Berkeley Bionics' military exoskeleton.


And now the Berkeley Exoskeleton...



Different target uses, both cool :D

Japan's Evil AI Company


Cyberdyne - this is the name of the corporation that created the evil AI Skynet in the Terminator Series, and now, it is the name of a Japanese company that produces exoskeletons. Guess the name of their flagship product... that's right, HAL, another evil AI!



Their technology (like their naming tendencies) is in fact amazing...


HAL stands for "Hybrid Assistive Limb" and it's targeted for medical use. It does what most exoskeletons do - increase power. However, there are a few reasons I like HAL more than other exoskeleton designs.

First, the exoskeleton reads electrical signals produced from motor neurons and translates this into action. In fact, HAL reads the motion faster than humans do, meaning it can move before you do. 



Second, with HAL, you can lift from 2 to 10 times as much, according to the FAQ. Also, the battery life lasts 5 hours, which seems surprisingly long for an exoskeleton of this type. Target capabilities are similar to Raytheon's Sarcos, but that's tethered (for now). Berkeley's exohiker lasts 21 hours, but that's a different type of exoskeleton.

Originally, the price appeared to be around $4200, which would have been amazing, but we don't know for now. It may go up to $20k. Cyberdyne is currently in mass-production, but apparently, from the website, is only selling to Japanese customers (there are plans for expansion though)

Recently (Aug 3rd), Cyberdyne had a demonstration of some company employees walking around using half of the suit:

Why the Touch Book (and Similar Netbooks) will be Awesome for Students


I've been pretty hyped up for the Always Innovating Touch Book since I found out about it off http://www.tabletpcreview.com/. It seems like the best design yet in the "cheap tablets" category.

Students usually already have a laptop and cell phone. The Touch Book fits the niche right between the two as an all-in-one portable device. The main limitation at this point is the lack of ARM support in software, but this shouldn't be too much of an issue. On the human side, a limitation is tech-savvyness. Compiling software for ARM may be confusing for the average user. Unfortunately, Windows 7 won't be supporting ARM. The other faults may be improved by doing some improvements:

http://mirumir-i.blogspot.com/2009/08/my-dream-netbook-aka-12-improvements-to.html

Onoes where's the computer?

Now that we're through with the limitations, here's why the Touchbook is awesome :D


  • Due to the long battery life, it only needs to be charged once a day, preferably in the night.
  • Students can add a GPS USB dongle into the internal USB ports, saving money on GPSes
  • Students can bring all their books in one device, if there are ebook versions of their textbooks (on that note, textbook manufacturers should definitely make all their textbooks available as ebooks)
  • Tablet form factor allows easy note-taking. Although you won't be able to use OneNote(the ultimate note-taking software, imo), Basket Note Pads provides a viable alternative. There's also a pressure sensitive screen that may be able to act as a rudimentary Wacom-style tablet.
  • Since it's cheap ($400 for everything, free software), students can still afford a normal laptop, desktop, or tablet pc.
  • Instant-on. Need info? Whip out your Touch Book. No more waiting for that hibernate screen...
  • Makes spaced-repetition study software like Anki and Mnemosyne much more portable. (Well, it makes all software more portable xD but spaced-repetition software is best used with regular check-ups and reviews, so it's more relevant). You can keep all your study tools in one portable little package!
  • While the Atom and ARM are very close in speed, the Touch Book's ARM OMAP3530 Cortex A8 processor means little to no heat
  • When new tech comes out, the Touch Book doesn't just flounder into obsolescence like other netbooks. Slate mode can be used as a digital picture frame, weather display, alarm clock, video player, GPS...etc.


Other Touch Book-like products that I see potential in are the Asus T91 and T101h, Gigabyte T1028, and Intel Classmate. There's also the rumored Mac tablet... The Asus products especially are appealing, since multitouch Windows 7 versions are coming out soon. If you want an informative comparison, look here: http://www.touchbookfans.com/forums/showthread.php?p=414 


The T91 - Wait for the multitouch/Windows 7 version

At the moment though, the Touch Book seems to be the best option. Unfortunately. production and shipping seems to be rather problematic (there is a backlog of pre-orders), so if you order now, it may take a while before it arrives. It may be prudent to wait for reviews.

Combating Apathy (Education Ideas 1)

Recently, I found out that my old Chinese School had almost died completely, partly due to this recession. In one year, they lost around 100 students. I used to go every Friday night in the school year. While we had lots of fun, for many, there was little learning going on. Supposedly, we learned the language and culture of Taiwan and China. In actuality, many learned nothing. In the higher grades, apathy spread like a disease. Few people did their homework. People skipped classes and many dropped out altogether. Because teachers didn't like failing students, grade inflation run rampant. A huge gap developed between the students who were doing well and those who weren't... 


 I'm sorry to say that I was one of the students affected. I believe it started in 9th grade. No one seemed to care (although some undoubtedly did, like the 7th grader in our class).

So what can we do to fix this ongoing situation? I believe reform should begin with the teachers:

  1. Make grades worth something. By late junior high and high school, kids seem to realize that grades from Chinese school don't affect their academic careers. Perhaps arrange something with local high schools so Chinese school grades can be counted for high school credit. Also, look at point 2. Create dedicated AP and SAT curriculums. More controversially, try returning a portion of their tuition in return for good grades.
  2. Don't be afraid to fail students and hold them back a grade. This point and point 1 work together. Teenagers can be extremely self-conscious and would work hard to avoid staying back a grade (and having their egos destroyed).
  3. Teach to a more standardized curriculum. At this moment, although every teacher uses the same books, the number of words they teach and difficulty levels vary greatly.
  4. Share teaching resources! Don't hoard them for yourselves! Ugh... My mom is a teacher at this Chinese School and I've seen how human and selfish teachers can be. As long as people are credited, it should be fine.

I'll share more ideas and student-side issues when I think of them :D

Finals over! Quickie Update

Excuse me for the lack of a post yesterday; I just finished Macroeconomics finals at a community college close by :D While it wasn't exactly a lot of fun, I am no longer a financial illiterate. The class also reiterated the joy of learning for the heck of it. I checked out all sorts of books on finance and investment and hope to learn even more.

The class was also significantly easier than my normal university classes, and I don't have to worry about grades (my uni doesn't count the credits). Thankfully, this made the period relatively stress-free.

On another note, I took 3 showers yesterday to try to get rid of the smell of that nasty tersi foam stuff. I still smell like sulfur. Hopefully my dermatologist assigns me another medicine before I head back to college. Read more...

Cinque Terre, Italy

This is another set of Dad's photos, this time of Cinque Terre in Italy. He took them on the same trip to Barcelona November 2008.

Personally, I think this place is awesome. Wish I were there.

Dad's going to be giving me more photos to put up, so if you like them, stay posted!

Bye Bye Patchy Itchy Skin!

This is to help anyone who might have the same problem diagnose themselves:

I've had patchy skin since I was in jr. high. My skin itched when I got too hot/exercised too much. I looked online and at first thought it could be vitiligo. However, my skin wasn't turning pure white.

Today, I finally went to the dermatologist to get it checked out. Apparently, it's called Tinea Versicolor and is an infection by a common yeast relative, Malassezia globosa. It likes oily skin, and probably because of that, commonly occurs in teenagers.

Well, there's a way to treat it, and it's with an unpleasant-smelling lotion called tersifoam:



I didn't post any pictures of skin cause honestly, it's not pleasant. But if you want to check, go google it. 

P.S. Don't worry, it's not contagious, and everyone has already has small numbers of M. globosa on the skin
