More lightning updates

Over the past two weeks, I’ve flown to California, visited my friend Arvin, attended ASPLOS 2006, flown home, spent some quality time with my lovely wife, eaten lots of barbecued meats, and attended the BeerAdvocate Belgian Beer Fest. A quick rundown:

- California/Arvin. Flew out Friday evening and arrived in San Jose around 8 pm. Had a tasty sushi dinner with Arvin and his girlfriend Melissa. The sushi rolls were more “out there” then what you typically see here in Boston. I enjoyed it.

Saturday we did go-karts at GoKart Racer, which is a “real” karting place with two serious tracks and timing and lots of stats. They even put your times up on the web. We did a practice session, then qualifying and a 15-minute race. My practice times were pretty terrible and varied wildly, but my race times were remarkably consistent. Both Arvin and Melissa beat me, but I didn’t embarrass myself for never having done it before. I thought this was awesome, and I would love to do it again. There’s a similar place in Boston called F1 Boston, maybe we’ll go for my birthday (hint, hint :) ).

Later Saturday we played poker with some of Arvin’s friends. Ran into Sophia there, which was a pleasant surprise. Haven’t seen her in maybe 2 years. Hung out with these people the rest of the day, played Set, had Korean food for dinner, then watched a kung-fu movie while the girls played Sudoku.

Sunday, Arvin and I went to this bar called Toronado in San Francisco. BeerAdvocate says this is the best beer bar in SF, so I wanted to go and try some West Coast brews. I was not disappointed. It’s pretty divey, in the Haight district, but they had great beers and very good prices (~$4 for a reasonably large serving). I had a Pizza Port Hop Suey (double IPA) and a Full Sail Vesuvius (Belgian-style tripel), and I picked an English Ales Black Prince Porter on cask for Arvin. All were very tasty, but I was most impressed by the cask porter. Delicious!

- California/ASPLOS. Sunday evening, I went to the San Jose Hilton for the welcome reception for ASPLOS. Met up with Sam right at the sign-in table, then went in to schmooze. Met lots of cool people. Actually, that pretty much sums up my conference experience. I met lots of cool people who are doing interesting things, and I got lots of ideas from listening to the talks and talking to people. It was especially fun to meet the people from UT-Austin with whom Sam had done his graduate work. Also, it’s cool to meet people whose papers you’ve read or whose textbook you own. You get to put a face with the name, and their research goes from something intangible to the product of an actual person’s effort and intellect.

- Quality time with the wife/barbecued meets. Yes, these go together. :) When I got back, I talked Catherine into going to the Midwest Grill for dinner on Thursday night. This is one of those Brazilian BBQ places where the waiters walk around with giant hunks of meat on swords, and you call them over and they cut off a piece for you. All you can eat meat, heavenly. Catherine is not a big fan, but I love it. I’m just glad that she humors me and comes with me.

- Beer fest. Saturday night, Cath and I went to the Belgian Beer Fest with her father and a couple of family friends. I made an effort to try beers that I haven’t seen or wouldn’t normally buy, so that meant avoiding the local Belgian-style stuff (which is usually excellent, don’t get me wrong), and going for the authentic Belgian beers. I tried a couple of traditional lambics, and I liked them, in particular the Boon Geuze and the Cantillion Geuze. Also enjoyed the Urthel Hop It and Quadrium. Frankly, my palate was too tired for me to pick my favorites; I couldn’t judge subtlety and would tend to just pick the most outlandish beers. But I can’t say I had a bad beer the whole time. I always have a great time at these fests, and this one was no exception.

Free wireless – security implications?

I’m sitting in the last talk from this year’s ASPLOS. There’s an open network here for conference-goers to use. Maybe 1/8 of the people in this room are currently typing away on their laptops. I’m sure this has been done, but I’d like to set up a packet sniffer and just capture data on what other people are doing. I bet you could get all kinds of secret data (passwords, etc.) from people using non-secure communications methods, even at a conference where everyone should know better.

Let me give an example. On my laptop, I use Thunderbird to check both my Tufts and Comcast emails. Comcast allows you to check your email with a plaintext username and password, or you can use SSL to encrypt it. People *should* use SSL, but they probably don’t. When I checked after checking my email the first time, I was broadcasting my username and password in plaintext. Very bad. And I use that password elsewhere. I fixed it, but anyone within range of my laptop’s radio could have logged that info.

I bet other people here are also leaking more info than they realize. Cookies, for example. Many websites have automatic login based on cookies, and the cookies are sent in plaintext. I could capture those cookies and use them to impersonate others.

Lots of interesting security problems here. Would be interesting to present the findings at the same conference where you gathered the data.

Lightning updates

A quick round of lightning updates on what’s been going on the past few weeks:

- Catherine ran the BAA Half Marathon on Sunday, October 8. My cousin Oh and I went down there with her and hung out while she ran, and later Catherine’s parents came down for the finish. A friend was also running, so we met up with his wife while he ran and had breakfast. It was a pretty cool experience. I got to meet Steve Runner, the guy who does the Phedippidations podcast that Cath and I listen to. The race atmosphere was very cool, with thousands of people all ready to run 13.1 miles. I thought I would be sad because I still can’t run because of my knee, but it actually wasn’t that bad. Cath did very well, finishing in 2:21, which was a good bit faster than her goal of 2:30. Yay for Cath!

- This past weekend, Cath and I went to Julio’s Liquors in Westborough for their Fall Beer Classic. This was pretty much a free beer fest. They had reps from maybe 30 different breweries, pouring most of their beers. There was no fee, though we did donate $4 to some charity for tasting glasses. The beers were delicious. I drank mostly strong beers for some reason, and my favorite was probably the Alesmith Speedway Stout. This was an imperial stout brewed with coffee, and among BeerAdvocates it is considered maybe the best imperial stout. It definitely lived up to its reputation; even after I had tried 10 other strong beers, the Alesmith made me sit up and take notice. It was that good.

This Fall Beer Classic thing was awesome. It was maybe 80% as good as a BA fest, but totally free and less crowded. A++, would attend again.

- Next week I am attending ASPLOS (Architectural Support for Programming Languages and Operating Systems) in San Jose. The conference doesn’t start until Sunday night, but I’m flying out tomorrow to spend a couple of days with Arvin. Should be awesome. I’m also excited about the conference. I’ve never been to a big conference like this before. Sam says I shouldn’t go to all of the talks; instead, I should mingle and meet people. I’ll try to do that, but it’s tough to be outgoing all the time.

Beer fest tickets = acquired

Cath says that’s a dorky title, but I’m comfortable with what I am. :)

Went by Harpoon this morning to pick up tickets for the BeerAdvocate Belgian Beer Fest later this month. We have quite a crew going: Cath and I, Cath’s father, and a couple who are family friends of Catherine’s. It’s going to be awesome. I’m excited to try some of the Belgian beers I usually don’t drink, such as the trappists (aside from Chimay) and the lambics/krieks.
