2nd Amendment Rights?

Yes, peanuts are getting more and more dangerous. Fortunately, we're not from from the 2nd-Amendment kicking in and preserving our right to bear peanuts.

Before long, they'll be as dangerous as fruit and we'll have to learn self defence...

Right now, Mr Apricot, come and me with that peanut !!!

(shoots him, eats the peanut)

The deceased, Mr Apricot, is now 'elpless

IBM explores 67.1m-core computer for running entire internet

Alan Walker

Market share vs. market size

I can imagine the discussion with marketing...

Researcher (proudly) "We've come up with a computer that can run the entire Internet".

Marketing (orgasmically) "Ooh, ooh, that's incredible. How many of these do you think we can sell?"

Researcher (sheepishly) "Ummm, errr - one"

Marketing (rolls eyes, sneaks out of the room)

Mainframe now obsolete for data warehousing

Alan Walker

Where are the benchmarks?

Two thoughts on this:

1) I haven't seen any TPC data warehousing benchmarks vs. Oracle / Teradata / others. If the mainframe were truly faster and cheaper, they'd be publishing objective data. Show me the numbers!

2) A mainframe can only replace hundreds of PCs when the PCs are not busy. Consolidation and virtualization is great in this environment, and Xen / VMware / Solaris containers can also do this. There's no magic about a mainframe CPU, it's not really any faster than an x86 chip (I've benchmarked both).

Is the relational database now a commodity?

Alan Walker

Not a commodity yet...

A couple of random thoughts:

1) Databases aren't interchangeable, as many programmers tend to use evry last feature in the book - and the vendors want you to do that as it creates lock-in. So, moving from one database to another for many applications can be a painful experience and involves a lot of retesting.

2) Resilience and 24/7 operations just aren't there yet. We've seen the "unbreakable" just lock up for no reason, or corrupt its own data pages.

That said, for many users and many applications, databases are fast becoming a commodity. Download MySQL and you can be up and running pretty quickly.

Microsoft and Cisco eye Iceland for green server farms

Alan Walker

And the best part...

A big part of energy consumption is the air conditioning to keep the servers cool. In Iceland, you should be able to just leave the window open instead.
