It was certainly helpful for me to understand how interface builder and objective-c interactive. The book helps understand that very well.

Main-memory databases in the early 90s were figured out the issues when all pages can be accessed in constant time. A solid state disk characteristics is no different from main memory.
So far it seems this is only a VPN that provides encryption between you and google servers. I understand it would improve security when using free Wifi or public terminals ?
Where are the hotspots? Also why would it only work in SF?
>The reason government regulates cigarettes and booze is because your use of them can cause harm to other people. Government is not protecting you from yourself, it protecting others from you.
That is bogus. What harm can one cause by smoking a cigarette in my own house without no one around. Yet the governments regulates it.
Governments have always regulated (often based on political pressure). We might not agree with the regulations but still we have to follow them.
We all can love Google's technology, but allowing Google to monitor email communications is a bad precedent.
I am sure if Google gets away with this, Microsoft will be not far behind. Microsoft is already going to have a indexed file system in Longhorn. Then with hotmail/msn they will provide a backup space and then target ads based on this information. So Microsoft will have everyone personal computer's indexed.
Gmail might be the first communication carrier which is going to listen to personal communications and sellwhat it learns information to its customers.
Imagine the phone company listening to conversions and then sending you offers for products based on what you talk about.
This is very different than spam/virus scanning. In that the email is scanned but compared against a pattern. In Gmail's case, the email is scanned and information is gleaned from it.
I think Gmail starts a dangerous precendent. Once companies think it is okay to listen to personal communications then the possibilities are scary!
The project is a interest idea. But do not see a real world practicallty. The examples mentioned in the article are useful for publishing research papers.
But I do not see a human sitting and drawing pictures to find things realiably.
"Launch file" after downloading has been enabled for.exe files
Is this a feature that just encourages more viruses?
Typical Microsoft poducts often having similar functionality
and the mom-and-pop crowd ends up messing their computer!
Oh! I forget the mom-and-pop crowd does not use Mozilla.
Main Memory Databases have been researched for nearly 10 years now and there are a number of commercial products.
For details you can check out: TimesTen Polyhedra DataBlitz
etc..
The idea it to have enough RAM to be able to store all the database in memory. This gives higher performance than a fully cached Oracle for two primary reasons:
- there is no buffer manager so data can be directly accessed.
- the index structures use smart pointers to access the data in memory.
Typically the data is mapped using mmap or shared memory. Each application can have the databae directly mapped into its memory space.
For providing persistence, typically main memory databases provide transaction logging and checkingpoint to be able to recover the data. Various techniques have been developed to be able to do this without affecting performance.
This is similar to what Guliani did in NYC with his quality of life initiative.
For minor crimes (jumping subway turnstile etc..), individuals were taken to the police station and finger printed. The rational given was when individuals move onto bigger crimes, they are easier to catch.
NYC did not publish this list as a list of criminals for the future, but they just increased their database.
In the US, privacy of a individual is NOT a fundamental right and the state will continue to collect as much information as they can of their citizens.
That I can put my laptop to sleep, and wake immediately, and still have many TCP/IP connections open, is incredible to me.
I would agree that MAC OS X being a UNIX is much more stable than older versions.
But most folks I know will not change until they are use their 56K modem to connect reliably to the internet. The v90 modem scripts have been completely flacky in Mac OS X , and most users boot up OS 9 when they want to connect to the internet.
iChat is actually a nice chat client: unobtrusive, mostly well-integrated into the system and Address Book, and easy on the eyes (it's also a little buggy; expect a few crashes).
That seems that a bad design choice. It has
a Microsoft feel to it , where applications
have the ability to mess with each other
and end up being unmaintainable or break basic
security models.
From a social viewpoint, folks who use AOL
prefer having different identities and
not have their real name from Address book
show up to the whole AIM world. Hence integration
does not seem to be very usable by real people.
Microsoft had a conference of some sort this week or last week in Seattle where they invited faculty from all over the world to increase their interaction with academia.
I am sure various proposals would come out of this: - windows source code to academia for students to hack with. (Beats me why would any student want to do this;-)) - more MS sponsered 'research' ofcourse based on MS technology.
It sucks a monopolistic company with money will decide what students are taught in CS/EE departments around the world.
The short answer is yes, they
have most of the unix goodies. I had the same question before I bought
my PowerBook. I walked into a Apple Store
and twiddled around in the Terminal
window to check if my unix goodies are there. Perl, tcsh etc.. is standard. gcc is part of developer CD (free download)
The link has some of the answers you are looking for. Though I would recommend walking into a Apple store

Does the group you are going to work in excite you?
It should be a small exicting group and people.
In large companies, work culture within different organisations
can differ.

note it does not sem to work now,
I was able to get the OS X PPTP client to work with a generated
user/passwd.
It worked for a while. Now it seems to have stopped.
So far it seems this is only a VPN that provides
encryption between you and google servers.
I understand it would improve security when
using free Wifi or public terminals ?

Also why would it only work in SF?
Seems like vapourware to me.
I was able to cancel my Vonage subsciption.
But to return the box, I did not want to pay the postage.
So I walk into their office in NJ. I try to create a scene
and leave the box. But they refuse.
I had to go next door to a post office (reallly right next door),
and mail it to them.

Yes, all email is parsed/read and stored by _somebody_.
But NO ONE indexes email messages to gather information
and sell this information to advertisers. This is where
Google is crossing the line.
If the phone company listened to conversions
and send targeted advertisements based on what
they listen to. Would that be okay?
We all can love Google's technology, but allowing Google
to monitor email communications is a bad precedent.
I am sure if Google gets away with this, Microsoft will be not far behind. Microsoft is already going to have a indexed file system in Longhorn. Then with hotmail/msn they will

Since webmail is simple to use and requires no configuration of email clients. Most users understand web browsing.
Other than the /. crowd, who knows
the meaning of POP3/SMTP.
Gmail might be the first communication carrier
which is going to listen to personal communications and sellwhat it learns

Oracle was the first to have the restriction
for publishing performance data.
