Jordi, MA, Laia and Jana

Jordi's second daughter was born this week, on Wed morning, congrats!

Everything went great, very smooth. They named her Laia. He hasn't been able to send me the pics just yet - he sent an email Thu but had forgotten the camera at the hospital.

Instead, he sent a few pics of Jana, his first-born. She and Biel - the son another one of best my friends from childhood, Toni Serena - play together at the zoo:





Geek

And for the random geeky comment of the day:

Windows XP SP2 introduced a few new twists to TCP/IP in order to babysit users and "reduce the threat" of worms spreading fast without control. In one such attempt, the developers limited the number of possible TCP connection attempts per second to 10 (from unlimited in SP1). This argumentative feature affects server and P2P programs that need to open many outbound connections at the same time.

The "forward-thinking" of Microsoft developers here is that you can only infect 10 new systems per second via TCP/IP. Mmmh... If you also consider that each of those infected computers will infect 10 others at the same rate:

second 1: 1+10 computers
second 2: 10+10*10 computers (110 new ones)
second 3: 10+100*10 computers ( 1110 new ones)
second 4: 10+1000*10 computers (11110 new ones)
...
all the way to 10*60 + 10^60 computers in a single minute (that's a number with 60 digits, or it would far exceed Earth's population).

So, we've established this is not going to stop a worm spreading. At best it's going to delay it a few seconds, limit possible network congestion a bit, and limit the use of your PC to 10 connection attempts per second in the process. This is all fine, but still, users should have the option to easily disable or change the setting. Although the setting was registry editable in XP SP1, it is now only possible to edit it by changing it directly in the system file tcpip.sys. To make matters worse, that file is in use, so you also need to be in Safe mode in order to edit it.

Either that, or use a tool like this:

Got a message from my parents, they are at the beach this weekend, cool. It's Labor Day in Spain, and they have Monday off. Must be nice

Here's a pic my mom sent of her in a new jacket at home, and also a pic of my sister-in-law's birthday a couple of weeks back. Nice cake



Back

Back in NY, at least for a couple days. Will take me a while to catch up. Got up early today, been doing things around the house all morning.

Random comment: those plastic containers used by many consumer packaged goods are such a pain to open. I end up cutting myself half the time, and cursing. The manufacturer's goal is to deter shoplifting by making it super-hard to get the packages open at the store. The end result is that the packages are very hard to open even if you use power tools, 5 knives, and 2 scissors.

Went to the dentist yesterday. Standard scheduled checkup. No problems. Funny how they always tell you that you need to floss more, and point out your gums bleed a bit. The thought that always comes to mind for me is: "Well, maybe they bleed because you are poking around in my mouth with a sharp metal object!"

Will be in Cinci again Wed, Thu, Fri most likely.

I have to post a couple pics from Vegas when I have a minute.

Thu

Late dinner last night. Met Maria, a friend of Charles', briefly. She is considering moving to NY for work, currently working at P&G, wanted to get my impressions on moving from Cinci to the Big Apple. She has a PhD and works in the Chemistry/Pharmaceutical area I believe. Interesting.

Will be a busy morning in the Cinci office. Will catch a flight back this afternoon.

Talked to Bill late last night, he went out with Sanja, it went well.
