To Fast? Too Slow? May 20, 2008

I’ve been living on borrowed time. My big home machine’s system disk has been making “chirping” noises for the last several months. And quite nicely, my OS (yes, Vista) warned me before that that the disk was heading towards the dustbin when it started receiving SMART events from the drive. This weekend it finally got bad enough that it caused timeouts and system crashes.
Did you know, that in the time it takes to build less than 100 source files in the ATLAS software system you can:
- Shut down your (already totally backed-up) computer
- Open it up, remove the old hard drive, replace it with a new hard drive
- Boot on a USB key containing Vista
- Tell it to start restoring the computer from the backup
- Get a glass of orange juice
and the build wasn’t quite finished yet. I was going to say “that was easy!” but then I realized that racing against an ATLAS software build isn’t exactly a badge of merit.
I wonder if the multi-core future will fix this slow-build problem? I can use more than one core to do my builds, but everyone has told me not to do it because dependencies aren’t tracked correctly and you’ll end up with a mess.
Science Social Networking May 19, 2008

Now. I might be more willing to spend time on a science social networking site. I can’t tell you exactly what it would offer to get me there because I’m not 100% sure what I want (see this comment on previous past). But…
At any rate, I stumbled on this post on Ars the other day:
When it comes to thinking and working internationally, scientists don’t always do as well as other professions. Scientists trained in the developing world often relocate to the US, Europe or other industrialized nations, taking with them their expertise. The New York Academy of Sciences is determined to do something to help less-well-off nations strengthen their scientific institutions and development, and it’s harnessing the internet to make it happen, through a site called Scientists without Borders.
Clearly not aimed at particle physics (hey, I think we do OK on international collaborations!), still, it sounds interesting. At first, it looks like a contact site - you say what you are good at and then when someone comes along searching for a collaborator they might find you. There is an interesting second half to this site:
This tool will eventually create a record of accomplishments that also identifies the next steps for solving specific problems.
That got me to thinking. We already have such a tool in particle physics - the paper archive (arXiv). I think if you built a physics social networking site you’d have to drive it with data from that site. Already, if you have a new idea, you might troll that site looking for others that have done similar things. Then you might read their papers, perhaps follow up with email or a phone call. Then you’d write your own paper. You’d send them an email about the paper (like a social networking notification) and then they would read it and, of course be impressed. After that perhaps the two of you would co-write the next paper and you’d gain entry into this other person’s network of collaborators. Or something. At the moment all that happens by email. Would it be better if it was somehow automated?!? I don’t quite see it. And how should the model be adjusted for experimentalists?
Maybe friendfeed needs to gets links when one of its members posts a paper.
Lighting no match for computers? May 17, 2008

It is 1am here, and there is a thunder storm raging outside. My first clue was all the lights flickered off and back on again. And yet no computers in the house crashed. Didn’t even loose my network connection! After this happened I took my earphones out and realized there was cheering on the street. The flicker had occurred up and down the street! I’ve never seen something like that and not lost all the computers!
Of course, by writing this I’ll be so screwed it will be weeks before I have enough working computers to post again!
I Don’t Get Social Networking Sites May 16, 2008
Posted by gordonwatts in computers, life.10 comments
I like not to think of myself as too old. You know. I still get it. I’m sure Julia, my daughter, will totally disagree with that in a few years.
But I just don’t get sites like MySpace and Facebook. I like the idea — I have friends all over the world now. Getting updates on what they are doing, where they go for vacation, etc. - all of that would be great. Heck - you know those little status messages people put into IM applications (like “Warm here in Marseille!” or similar) - I love those. Definitely makes me feel more connected.
But I can’t imagine using these things everyday - logging in, maintaining my profile. I already do enough of that with this blog. With Julia, and life here in France, and (especially) work, I never feel like I have enough extra time. The thought of having to maintain my personality on a bunch of web sites - basically duplicating information - is a pain. And having to log into each web site, each one having a different interface. Not for me, I’m afraid. Especially since Julia has arrived I’ve found my time is really at a premium.
This will become a worthwhile investment for me once everything can be aggregated on a local desktop application (yeah, I realize, old skol). I want something that I click on my desk top and then I can see what people since I last checked. Where I can write a few lines (i.e. micro-blog aka twitter), and it will be correctly distributed to all.
Heck - I’m already pissed off at comments in blogs. They are so local. It would be great to track comments. I make a blog posting. Someone riffs on that blog posting in a posting of their own, which generates further comments, which generates a further riff (Ok, that won’t happen with one of my posting) - but basically everything is part of a conversation. As far as I know there isn’t something like that out there.
Time that I might otherwise spend on a social website I tend to spend hacking or perhaps working on something “fun” - often the items are work-connected. Perhaps I am missing something because of that.
How about you out there? You use these social network sites? Is there one that pertains to physics?
Check out the IM Post Comments May 15, 2008

I wrote a few days about about using IM at work. Old people social networking (!?).
At any rate, the comments there are much more interesting than the post. If you’ve not read them I strongly encourage you to go back and take a look.
So I just counted up the # of contacts I have in my contact list: 65. Of those two are personal (my wife and her brother). A handful are MIT specific (4), the rest are all cms coworkers. - Mike M.
0 to 60 in 3 weeks May 15, 2008

One of the nice things about being on a new experiment is that I’m not key to its operation. If I don’t do something, or if I sleep late then the experiment won’t be impacted. Not having that responsibility is nice - relaxing. I’ve been operating like this for almost a year now. I and a student and a bunch of others have been working hard to release a note on bottom quark tagging calibration. Fun, and will become key when data arrives. But real data will arrive only if we are lucky later this year. So, not so much pressure.
But, frankly, I’m getting tired of no pressure! There is definitely a part of my personality that likes being in the thick of it.
About 3 weeks ago I started working on a high priority software task - modifying how we write out some of our b-tagging data. The reason this is high priority is we are preparing our software for the first data - so all major changes like this need to go in so we aren’t stuck with the data in an old format. A little bit scary - all of a sudden I’m giving updates in several meetings, I get asked about how things are going in random emails. And I’m deep in the middle of the code muck - something I really don’t understand at a fundamental level.
Have to say, it is fun!! Hopefully I won’t tire of the fun until after I’ve finished the task!
Core Dump May 12, 2008
Posted by gordonwatts in Fermilab, SLAC, computers, life.add a comment
A little bit of fluff. I suspect about half the people who read this blog already know this. I keep forgetting it — though I use the words “core dump” almost everyday (hey - right now I’m working on ATLAS software!).
The term “core dump” relates to an old type of computer memory, in use before the advent of silicon chips, which used grids of tiny magnetized rings to store information. When a computer program in such a system crashed, a record was created about the state of the memory. “Core dump” has come variously to mean any fatal error in a program, as well as slang for getting the long version of a story from someone.
This is from the SLAC today web mailing. The Fermilab version is a bit depressing right now: any day now the layoffs will be announced - and that day is going to be depressing when it finally arrives.
All Stand Still May 10, 2008

We were out having a pre dinner drink near the Vieux Port this afternoon when the square suddenly filled with people. Then someone blew a whistle. We were sort-of aware there were lots of people, but then after the whistle we looked around and noticed someone pointing a banana, frozen in time. What?? A weird sort of flash mob, perhaps? Plenty of weird stuff going on this afternoon in Marseille. We are going to miss Marseille when we have to return to Seattle.
You Know You Are a Physicist when… May 9, 2008

Noticing something very bad is about to happen when your child sits down on a raised plaque at the base of a tree, and you only have a split second to give warning, your brain comes up with the following sentence: “Honey - Julia shouldn’t sit on that inclined plane because it is covered in poop!”
Who Uses IM For Work? May 8, 2008
Posted by gordonwatts in physics life.16 comments
On the drive from Marseille to Genova I asked the 3 others in the car if they used Instant Messaging (IM). I was the oldest in the car (getting close to 42!) and the rest ranged from mid thirties to late thirties. All are like me in that they have permanent positions. All have students, though I was the only professor - the rest were at labs around France.
How many people used IM for work? None other than me. Who used IM at all? None, other than me. On the way back I was in a car with graduate students - so mid to early twenties - but I totally forgot to ask them. However, since I rode with their advisors on the way out there I can be pretty safe in guessing they don’t use IM for conversations about physics with their advisors.
So, I have a bunch of questions. Do people use it mainly for social interactions? Or am I just in a bubble and it turns out that lots and lots of people use it for work and I just move in the wrong circles?
It was the day, not much more than two decades ago, that HEP lead the world in computing hardware and (to a lesser extent) software. We had to push it forward - the power and flexibility was just not there. I think if you look at the way we operate now - it looks very similar to how it looked back in the ’60’s. Command line. Simple text editors (vi and emacs are BIG). Batch jobs. The older set are only just getting off pine - a text/terminal mail program (moving mostly to the FireFox mail mail reader, and some to web clients).
Is there something holding us back? Or are we as a field voting with our feet: these things don’t help us get new physics results out? Perhaps we usually are in labs where you can run from one office to another and so email is good enough? IM interrupts our workflow and so we don’t want to let it in? What about all those Web 2.0 tools out there? Much of that is based on social networks and so if a lot of physicists don’t get on there, then it doesn’t really help. Are we slowly building critical mass? Or does it just not excite us yet?
Comments?
Just to make sure I stay ahead of the curve, I’m trying out friend feed - think of it as a way to aggregate all of your online activities… Of course, I don’t have many online activities.
