Better Memory Chips

  

Engineering scientists at the University of Michigan have found a way to improve the performance of ferroelectric materials, which have the potential to make memory devices with more storage capacity than magnetic hard drives and faster write speed and longer lifetimes than flash memory.

In ferroelectric memory the direction of molecules' electrical polarization serves as a 0 or a 1 bit. An electric field is used to flip the polarization, which is how data is stored.

With his colleagues at U-M and collaborators from Cornell University, Penn State University, and University of Wisconsin, Madison, Xiaoqing Pan, a professor in the U-M Department of Materials Science and Engineering, has designed a material system that spontaneously forms small nano-size spirals of the electric polarization at controllable intervals, which could provide natural budding sites for the polarization switching and thus reduce the power needed to flip each bit.

"To change the state of a ferroelectric memory, you have to supply enough electric field to induce a small region to switch the polarization. With our material, such a nucleation process is not necessary," Pan said. "The nucleation sites are intrinsically there at the material interfaces".

To make this happen, the engineers layered a ferroelectric material on an insulator whose crystal lattices were closely matched. The polarization causes large electric fields at the ferroelectric surface that are responsible for the spontaneous formation of the budding sites, known as "vortex nanodomains".

The scientists also mapped the material's polarization with atomic resolution, which was a key challenge, given the small scale. They used images from a sub-angstrom resolution transmission electron microscope at Lawrence Berkeley National Laboratory. They also developed image processing software to accomplish this.

"This type of mapping has never been done," Pan said. "Using this technique, we've discovered unusual vortex nanodomains in which the electric polarization gradually rotates around the vortices".

A paper on the research, titled "Spontaneous Vortex Nanodomain Arrays at Ferroelectric Heterointerfaces" is available online at NanoLetters.

How To Install Garmin XT on Nokia e 63 (Symbian S60 v3)

I recently bought a Nokia e 63  and asked if the shop keeper could install Garmin XT for me. Guess what? He wants to charge RM 80 (USD 20) for that!



It turns out, it is pretty tough considering my lack of expertise when it comes to Symbian OS phones. I spent 3 days experimenting all possibilities to make it work on my phone. Since it took a lot of my time, I’m going to save yours by teaching you.

Before you do anything, and read all the instructions before hand. It’ll help you to visualize the process.

Download file contains

    * GarminMobileXTforSymbianS603rdEdition_50040.exe
    * GarminMobileXTFreeBasemap_4xxxx.exe
    * GarminMobileXTSupportFiles_4xxxx.exe
    * gmapsupp.img (Malaysian Map, with DUKE highway)
    * garmin_kgen.exe
    * 5800_manual.pdf
    * GarminMobile20_GarminMobileXTOwnersManual.pdf

    Note: You can skip part 1.

1. Setting up Apparatus, The Nokia e 63

   1. Back up all data using PC Suite (go to Nokia website).
   2. Soft reset by pressing *#7370#. Should take about 2-3 mins and you lose all your data (except on memory card). But don’t worry, you have back up remember?
   3. On your Nokia e 63, go to Application > Location > Positioning > Positioning Methods. Enable “Assisted GPS” and “Integrated GPS” ONLY. This will ensure you don’t get charge using WAP or 3G network for Internet.
   4. Go to Application > Location > GPS Data > Position > Options > Satellite status. This will show the satellite signals you’re receiving. Be sure you are outdoor in an open area. Balcony doesn’t work well, believe me I’ve tried. Once you’ve got AT LEAST 4 satellite signal, go back indoor, you don’t want people to think you’re crazy, waving your phone around.
   5. Now you’re ready for GarminXT.

2. Installing GarminXT on Nokia e 63

   1. Once you’ve downloaded, unzip the files to someplace accessible preferably on your desktop.
   2. Connect your phone via USB and select  ‘Mass storage mode’.
   3. From you PC, double click “GarminMobileXTforSymbianS603rdEdition_50040.exe” to install and wait.
   4. Double click “GarminMobileXTFreeBasemap_4xxxx.exe” to install. Wait..
   5. Double click “GarminMobileXTSupportFiles_4xxxx.exe” to install.
   6. Remove USB connection between PC and phone. When prompted ‘Launch GarminXT’ do not click Yes, just Cancel.
   7. From your phone, go to Menu > Settings > Application Manager > Installation files. There should be GarminXT.sis file. Install it.

3. Cracking GarminXT on Nokia e 63

   1. Tell yourself and say “Yes, I’m a cheapskate”.
   2. Run GarminXT from your phone at Menu > Application > Garmin. It will prompt you with some settings. Choose your preferable.
   3. Select “Use other device” when it prompts you to buy or trial. You will get a screen, “Where To?” and “View map”
   4. In GarminXT, go to Tools > Settings > About. Jot down “Card ID”, you will need it. Exit GarminXT
   5. On your PC, run “garmin_kgen.exe” and enter the “Card ID” from previous steps.
   6. Generate it and you will get a string of codes. Copy the codes to Notepad and save it as “sw.unl”. *Be sure you don’t save it as sw.unl.txt”*
   7. Connect your phone to PC and select “Mass storage mode”.
   8. Copy “sw.unl” to Garmin folder. Usually located at E:/Garmin.
   9. Copy “gmapsupp.img” from downloaded file to Garmin folder. “gmapsupp.img” is the Malaysian map.
  10. Disconnect your phone from PC.

4. Restore your Nokia e 63

   1. Reconnect your phone via PC Suite.
   2. Restore your settings through back up.

5. Setting up GarminXT on  Nokia e 63

   1. You don’t need your PC anymore. Shut down and conserve energy.
   2. Run GarminXT on your phone.
   3. Go to Tools > Settings > System > Remote GPS. Change to “Use Attached GPS” by disabling the “Bluetooth GPS”.
   4. Go to Tools > Manage My Data > Map Sets > MapSource. Make sure all maps are enabled.

6. Toying GarminXT on  Nokia e 63 .

   1. Switch off your fans and lights. Go out.
   2. Run GarminXT, (duh!).
   3. Select “View Map” and wait for a while. The satellite will find you. It took me 5 mins or so. Just have patience and faith.
   4. Now you’ll see where you are.
   5. Go back and select “Where To?”. If you’re at home and wants GarminXT to store you current location as home, then select “Home”
   6. “Where To?” is rather confusing. I usually use “Where To?” > Point of interest. There’s lots of shopping malls, hospitals, banks, ATM machines etc. from there, you’d know where to go.
   7. Pat yourself and say “Well done”. The rest is up to you.

DiGi Easy Prepaid gives you FREE calls & SMS to your “buddyz”.

DiGi Easy Prepaid gives you FREE calls & SMS to your “buddyz”.

Nowadays when DiGi gives something for FREE, I need to think twice, “how long will it be free?” Anyway, if it could benefit you until it is no longer free, then this is still useful isn’t it? ;)
So what is exactly free with DiGi Easy Prepaid? Have you heard of Friends & Family (FnF) ? I am sure all DiGi users are familiar with this.  They still retain FnF in the new prepaid plan but only limited to 3 numbers. Does it look bad? Actually no, because the other 3 number is under their new feature which is called “Buddyz”. Alright, what the heck is this Buddyz? This is where things comes for FREE :) . For these 3 Buddyz numbers, you can call and sms for free.
Not only that, you will also get 10 FREE sms to any network when you reload RM10 :) . Yeah, it is all for free (but hopefully they don’t come up with silly restriction later like how they did for DiGi Campus). Oh ya, another thing that is worth to mention. You will only be charged a maximum of RM3 per day for your internet usage (the old plan was RM5 maximum, am I right? )
Adverts:
Below is the plan table :
* Please click on the image for larger view.
The unfortunate thing about this new plan is, if you are a DiGi Prepaid (RM1) user, you cannot convert this plan. Yes, you have read that right. Conversion from other plans are allowed except for :
  1. DiGi Prepaid (after daily usage reaches RM1)
  2. DiGi Biz Prepaid
  3. DiGi Family Prepaid
  4. Edisi Khas
  5. Prepaid Internet
  6. DiGi Prepaid™ Campus
If you are on any other DiGi prepaid plans except for those above, you can change to this DiGi Easy Prepaid for RM3 (yes, RM3 will be deducted from your credit).
Alright, now let’s discuss about the core features of this prepaid plan which is Buddyz :) . Similar to Friends & Family (FnF), you can add another number into your Buddyz list. It is only limited to a maximum of 3 numbers & all these 3 numbers must only be DiGi numbers (but it can be under any plan, prepaid & postpaid). The 1st 3 addition is FREE. After you have used up all the 3 slots, you will be charged if you want to change any of those numbers. How much will you be charged? It will be RM10 per change. Quite expensive compared to FnF change isn’t it? Well, since you can call those numbers for free, I think RM10 is fine :)
So, do you have any questions? Let’s discuss about it here :)
UPDATE 2/10/2010 : As for calls, you can’t call it entirely free. There is a limit of 60 hours per month. This is what DiGi says at their T&C :
If the Subscriber consistently exceeds the usage of 60 hours a month of FREE Calls, DiGi reserves the right to disable the Buddyz™ call feature without any notice. As such, the Subscriber shall continue the service thereafter without the Buddyz™ feature. It must be emphasized that DiGi shall not provide any notice whatsoever to the Subscriber prior to or after exceeding such limit.
Obviously you are at risk of being converted to normal plan but hey, 60 hours per month is huge. It will be about 2 hours per day :) . If you want to speak longer than that, you might as well go & meet up the person directly.
Another thing worth mentioning. As for the free SMS that you will get when you top up, it will only be a maximum of 30 SMS given at a time. So you may not want to top up more than RM30 at a time. :P
It is better to read up their T&C to understand better on the limitations of DiGi Easy Prepaid (LINK)
UPDATE 5/11/2010 : DiGi Easy Prepaid sim pack’s price is now RM16.80. You can still find some old stock for RM10.80 (if you are lucky and the dealer is not updated about this) but DiGi has officially increased the price to RM16.80. Pre-loaded credit is still the same – RM8.00.
