Muli Ben-Yehuda's journal

I signed up for the gym today. On the one hand, I’m a firm believer that shame is a great motivator, which leads me to suspect that if I commit to writing about my gym escapades (and the associated diet, etc, etc), I’ll actually get stuff done. On the other hand, once I get in the groove of things, I tend to go to the gym a lot, and wouldn’t want they gym experience to overwhelm the other stuff I write about. So, how to strike a balance?

Answer: the muligymdream community, where you can read my uncensored and most likely highly boring gym escapades, should you wish to. This journal will retain its usual non-content.

P.S. if anyone reading this is in the middle of a diet / exercise regime, and wishes to write about it on muligymdream, let me know. United, we stand. Alone, we roll along…

I haven’t written one of these in a while, let’s see if I still remember how.

Spent last week at Austin, Texas. Two days at the Austin Xen summit, and then the rest of the week with the LTC-Xen crew. Mostly it went very well, and the summit was much more interesting than I expected it to be, but we also hit a few snags on the HW side of things. Actually, “snags” is putting it mildly, “bloody painful razor-sharp blades” is a tad more accurate.

This week has been spent trying to catch up after I landed on Sunday evening. My sleep cycle is all screwed up, and my TODO list is growing at a very alarming rate. I better stop blogging soon and start shrinking it 🙂

We are working on an OLS paper proposal on Linux and Xen exploitation of upcoming IOMMUs, which I will post here after we finalize it. I guess that means I’ll attempt to get to OLS again this year, even though I didn’t intend to after last year.

No word yet from Usenix on the two papers we submitted. I am told the acceptance rate this year will be 10-15%. Ouch.

What else? spent most of the week battling with HW, and the battle is not nearly done yet. We are making headway, but paying through the nose for every inch of ground we take. Have devised a circling maneuver to be executed once we take the fortified position immediately to the front. There’s no point in trying to flank it, it must be taken.

I have been reviewing many papers lately, for research and patent purposes. You can see an up-to-date list of interesting papers at citeulike.

Canceled my talk at OSDC and will probably not attend. Can’t afford the time right now. Also, declined to give the drivers talk in the Technion. Can’t afford the time for that either.

Plans for next week: resume the battle and make headway on the bringup; study for upcoming exams; finalize OLS paper proposal and start writing it; slink back to the gym, and don’t look back.
