Drifting phases and noise in phase-change memory

ibmzrl

Re: This is actually kinda cool

The heat generated is mainly related to the write power.

Projection allows smaller volumes of phase-change material, because it limits the high resistance-state of the cell.

Smaller volumes of phase-change material lead to a reduction in write power and thus in a reduction of heat generated.

So, it may be that a memory cell design with a projection layer generates less heat than one without a projection layer. - Wabe W. Koelmans

IBM punts cryptotastic cloudy ID verification services

Re: IBM and "The Man" do not need to be involved

In one scenario, the user can take his/her passport to the local Post Office. The post office will verify your identity and they will provide you with the credential on your smartphone. It could also be done by TSA at the airport, local police station, etc.

This will depend on the country.

Re: I like the concept

Yes, the team has published dozens of papers over the years. For a full list visit: http://researcher.watson.ibm.com/researcher/view_person_pubs.php?person=zurich-jca&t=1

Re: I like the concept

Hi, Dr. Mouse, yes, the concept of a zero knowledge proof has been around for 15 years. The cloud just makes it easier for developers to plug the Identity Mixer code into apps. You can download Identity Mixer from Git Hub today, but as you will see its complicated to deploy.

Re: IRMA

Hi, the first patents on Identity Mixer were filed in the late 1990s and early 2000s. The cloud is only for making the deployment easier for developers. You can also download the code right now from Git Hub.

Re: IBM and "The Man" do not need to be involved

Hi Charles, yes, it comes down to who do you trust. Your local Dept of Motor Vehicles could vouch for you and give you the credentials when you get your drivers license. Or perhaps the local post office can do it. Or it could be an international body like ICANN. You obviously trust your government with your data already, assuming you have a passport or license. Or you trust your credit card company or bank, assuming you have an account.

Tom Chiverton 1, you don't send your personal details to anyone, they always stay with you. That's the point. If you need to prove you are 21, the credential, which sits on YOUR mobile device or YOUR desktop, tells the 3rd party service, YES, Tom is "21 or older" or just says "Yes". The code answers on your behalf. Get it?

Re: Rate Limiting

Yes, the rate limiting is you. You control how many times you want to show your credential to answer the same question. The credential can also respond with, Alice is between 12-100 years old.

IBM claims new areal density record with 220TB tape tech

ibmzrl

Re: 15 years?

Actually the wait is due to you the user. We need to make the tape backwards compatible for two generations and if you jump from 10 TB to 220 TB this isn't possible. The technology from the latest demo will trickle out to make pieces at a time.

IBM details PowerPC microserver aimed at square kilometre array

Re: At least THAT one

The design will be water-cooled. This is just a testing platform. For details visit www.research.ibm.com/labs/zurich/microserver/
