Massive Bug in Intel, AMD, ARM and other Processors in Handling VM Memory

In the last few days, we started hearing about a massive bug in the implementation of the VM memory handling.

Intel has been frantically working on fixing host machines kernels in order to prevent one VM from accessing the memory of other VMs that run on the same machine.

Of course, most users are not going to attempt to read someone else memory so in that sense, most of us are relatively safe. But all of those who are not so lucky and have uninvited guests on their systems are running at very high risk. The information available from Intel says the memory is accessible only in Read mode. ...

Probably an action that would be used to clear everything out.

This is an interesting concept: have a tag that can clear everything that we have done so far and start over. If you have a single time line, this is certainly useful. Since version 3, however, we get the DefineSprite tag that has a very similar capability (except that it does not have the ability to delete anything from memory, this comes in version 5 with access to external animations that can be created and thrown away dynamically.)

Your cell phone is hackable...

This is a quite interesting article which I thought I should share and keep a copy of!

Most of us, even if we can determine whether a piece of software (or hardware!) can be hacked, we just do not have the time to spend on testing each device we use to ensure that no hackers will be able to get it. We rely on the manufacturer to do that work for us.

This article shows that even though all manufacturers have protections, all are vulnerable! And that means your data is vulnerable on your cell phones... Hope this does not scare you too much!

Note by the way that those people who have plenty of ...

A new kind of memory!

Researchers are always testing new methods to enhance computers. These days, as presented in the Physical Review Letters (Dec 29, 2008), people have been working on phonons. These are heat particules.

LinuxWorld Conference & Expo 2008

This year, 2008, I decided to register and go to LinuxWorld. It is in August and my kids are not at school so it was easy to manage. Also, I had to go to the French consulate to get a birth certificate for my daughter. In other words, I had the chance to do two things at once!

I found it quite interesting to hear that many people were not too excited about the event. Many of the people walking around are like me: they themselves sell their own Linux solution. In other words, they are not going to be customers. I had the chance to talk with Roger Levi, the Vice President of the Open Platform ...

AJAX, CSS, HTML, XML, SOAP, LAMP… and now Web 2.0?

Dear reader,

Yes. With all these terms, it is quite easy to get lost.

As a developer, my skills are quite extensive. I started with Logo, learned assembly language, BASIC, C, C++… and all these other languages in between, those that most people pass by such as Ada, Eiffel, Icon… And the languages you kind of have to learn because you’re in it: Bourne Shell, configuration files for 100 different software, Makefile, etc.

And once you know all of these languages, you think you’re done. Well… Not quite!

The web has got it’s own set of languages! It
