Senator Obama: Echoes of President Kennedy

Posted February 19, 2008 by Tom Comeau
Categories: Uncategorized

I was watching Senator Obama speak at a rally in Texas.  He mentioned JFK’s “never fear to negotiate” statement.  It reminded me of this:

      Above all, words alone are not enough. The United States is a peaceful nation. And where our strength and determination are clear, our words need merely to convey conviction, not belligerence. If we are strong, our strength will speak for itself. If we are weak, words will be of no help.

JFK never delivered that speech.  Obama is often compared to JFK, and I get the similarity.  I also get the differences.  I’m a Republican, so I’m disappointed that my party has nobody like Obama.  It looks like Senator McCain will have his hands full.

Audacious rhyme

It’s been a while again, mostly because I’ve been busy.

But this morning I was listening to Antje Duvokot’s Merry-go-round and was struck by this rhyme:

We are slightly scared of death, a little bit afraid
So we celebrate everything we can think to celebrate

I would never have put those two words together.

What it means to be rich.

I stumbled into an article in the Washington Post this morning that includes this comment about the aspirational difference between “middle class” and “rich.”

“The middle-class aspirations include a decent home in a good neighborhood with a good school, and the ability to save for college and to make sure that your children have the opportunities to put themselves on a path to match or exceed yours,” Bernstein said. “If you’re upper class, you think about whether you want to move your horse from one barn to another barn.”

There are several things I find interesting about this notion, including one that happens to be purely about timing.

Teela’s riding instructor (I’m Teela’s dad) just decided to move her business to Arizona, so several of her riding buddies are thinking about new barns for their horses. All but one of them probably makes less than I do. For sure, none of them are rich. I wish I could afford a horse for Teela – a good one – because she’s put a lot of effort into her riding, and is at the point where she could start to compete. But I really can’t afford one, and if I could, I couldn’t afford to keep it.

My household income puts me in the top 6.5% of US households. The NY Times defines “rich” as the top 5%, which is a mere $157,176 in 2004 dollars. I live in the third richest county in the richest country in the history of the world, but I still worry about whether I’ll have enough money to cover a major illness or injury; whether I’d be able to find a job before my savings run out; or whether, if I save and invest carefully, Teela can go to a first or second tier university.

We’ve done a lot of things well, and we’ve been very fortunate, but from either an income or an aspirational perspective, I don’t think I’m rich. That puts me closer to Hilary Clinton than Barack Obama on the definition of “rich.”

Some quotes I like.

Recently on the Manager Tools forums, I shared some of my favorite quotes.

(If you lead or manage people, as a boss, a project manager, or a team lead, you really should be listening to Mike & Mark’s podcasts. Even on the rare occasions that I really disagree, I learn something. I try, with some success to apply what I’m learning to my work. I’m a premium member.)

“Don’t be ridiculous sergeant. They can’t possibly hit us at this.”
- unknown officer, often attributed to a American Civil War General.

This is probably apocryphal, but I don’t care. The point is that the guys in the trenches are closer to the problems, so if you’re going to second-guess them, it’s best to do so from good cover, and concealment.

“It worked!”
- J. Robert Oppenhiemer, at the Trinity test.

This isn’t the quote usually attributed to Oppenheimer, but it is what eyewitnesses agree he said. I usually find it surprising when things work on the first try, particularly when it’s an entirely new system.

“Contact light.”
- Buzz Aldrin. (First words spoken from the Moon.)

When you are in the middle of doing a new thing, get the thing done before you worry about dressing it up. The “Tranquility base here….” line is a great one, but the first few seconds were still about making sure they were down, in one piece, and getting set up to get back off the surface in a hurry if they had to. They had a procedure for touchdown, and they stuck to it, even having just gone through an unexpectedly difficult approach.

“That’s enough of you. Let me talk to Beavis.”
- My brother, an Air Traffic Controller, to a particularly dense pilot.

My brother is both witty and subtle. He is also very well organized, and has little patience with people who aren’t prepared, particularly where safety is involved.

“Research is what I’m doing when I don’t know what I’m doing.”
- Werner von Braun

There is a companion to this quote, which I can’t quite place, that is something along the lines of …Real science starts when you say “that’s not right…” The other thing is, when you get stuck, don’t get frustrated, get interested.

“For every problem, there is one solution which is simple, neat and wrong.”
- H. L. Mencken

When people tell me to keep it simple, or that things should be easy, this is the one I remember. It is far too easy to jump to the wrong conclusion and hope the world is simpler than it actually is.

“Learn the rules so you know how to break them properly.”
- Tenzin Gyatso, 14th Dalai Lama

That’s my plan.

Why Seth Godin Isn’t Right.

Posted July 9, 2007 by Tom Comeau
Categories: Communication, GeekDad

Heidi Miller did a blog entry on The Dip, by Seth Godin a while back. The Dip is one of those little books that is a quick read, but takes time to really understand.

I’m not ready to say Seth Godin is wrong, but I’m sure he’s not right about The Dip.

The premise of The Dip is something I readily understand: The only cases where effort and results have a linear relationship are probably trivial or pathological. Godin’s example is smoking: The more effort you put into smoking, the more pleasure you get from the experience, until you hit a crash. The crash could be quitting, in which case you pay in withdrawal, or it could be cancer and heart disease.

For nontrivial things, you put in more effort, and initially it feels easy. But then it gets harder, and you have to decide if you’re in The Dip, or in what Godin calls the cul-de-sac. If you’re in The Dip, you should power through. If you’re in a cul-de-sac, you should quit now, before you waste any more effort. And if you’re going to quit in The Dip, you should quit too, because otherwise all that effort is wasted.

Godin describes several Dips, and they all do in fact look familiar. His Dips also don’t look like the kinds of problems I care about. Not that the ability to identify problems, invent solutions, manufacture products or design services, sell and deliver aren’t important. They are the kinds of ordinary problems that you can solve, or you can walk away from.

There are three very good reasons to ignore the distinction between The Dip and the cul-de-sac.

The first, oddly, is the very example Seth uses in starting to describe the cul-de-sac: The Space Shuttle.

Even before Columbia, for some of us as far back as Challenger, we understood that the Shuttle was a cul-de-sac. It was never going to give us cheap, routine access to low Earth orbit, and it was certainly never going to take us beyond that orbit, back to the Moon and on to Mars.

But it was, and still is, the only heavy-lift crewed launcher available. Godin is wrong when he argues that canceling the Shuttle would have created an urgent need for a replacement. Most of the people I know believe that canceling the Shuttle before a replacement was defined and started would have simply meant the end of humans in space, at least on US launchers. Even now we face a gap between the Shuttle and its far-less-capable replacement of many years, perhaps decades. We stick, in the cul-de-sac, knowing the Shuttle will never get better, because we need it to accomplish a larger goal.

That larger goal, building the International Space Station, is the second problem with Godin’s analysis: I can’t tell if ISS is a cul-de-sac or a Dip.

Even people who have worked on the program can’t tell if it will be another pointless boondoggle, or a National Laboratory to rival Fermilab or Lawrence Livermore. When the goals are more than ordinary, the ordinary distinctions of The Dip fail me. We have a great deal to learn about the Universe beyond, and a permanent presence in space may be the best way to learn many of those things. The only way to tell if ISS will be a Dip or a cul-de-sac is by experiment.

When we started a Science Fair at my daughter’s elementary school, I had no idea if we’d get any participation. None of the kids were required to participate, and most of them are involved in a lot of after-school sports and other activities. Even once we got people signed up, there was no reason to assume they would show up the night of the fair. But we kept putting more effort in, and now, four years later, the Science Fair runs without me.

An awful lot of things are like that: The only way to tell if you’re facing a Dip, or a crash, or a cul-de-sac is in retrospect. So you stick because you care about the outcome enough to risk a cul-de-sac.

The third reason to stick, when maybe you should quit, is because you care about what you’re doing enough to fail. Almost everything I do that is of any importance is about people, and I care about those people. The limit of my caring is defined by my relationship, and the limit of my willingness to stick is not bounded by my analysis of The Dip. Rather, my willingness to stick is bounded by the limit of my caring.

I have regular conversations with people who used to work with me. I’ll keep trying to help them as long as they keep coming back to ask for help. Some of those people keep getting better, but others are stuck in their own cul-de-sac, and some are currently working through a Dip. I won’t devote my whole effort to them, but I’m willing to spend a couple hours a week because they need the help. I believe that some of these people come back because they see I’m willing to work with people, regardless of immediate return. I hope that when I hit my dip, they’ll help me.  Working through somebody else’s cul-de-sac is an investment in my future ability to power through a Dip, with help.

The extreme case is my daughter. My relationship with her is independent of my expectation of her success or mine.  I’ll never quit.  Whether she ends up as a crack whore on the streets of Baltimore or Secretary-General of the United Nations, she will always have the first, best claim on my energies.  Calculations of Dip or cul-de-sac simply don’t matter, because I care more about the effort than the outcome.

Godin also argues that you should only start down The Dip if you’re going to be “the best in the world” when you’ve finished. I only have two reasons for ignoring that advice.

The first reason is that I do many things simply because I like them. I don’t get much time to ride these days, but when I do, I put my best efforts into the horse and course that I’m on. I am not ever going to be the best rider in any part of the world. I’m not even the best rider in my household: Teela has rocketed past me in skill and endurance in the last year.  I don’t care.  If I get a chance to get in the ring or on a trail with her, I’ll grab it and enjoy it while it lasts.

The second reason is that I’ve learned in the last decade or so that I have no idea what I’ll be best at. I thought I would be a terrible parent, and that a child of mine would end up psychotic. I seem to have been wrong about that. I thought I would hate being a manager, but on good days it is very satisfying and on the worst days I still feel better for doing it. (It’s the days in between that are hardest.) I thought our plan, three years ago, for changing the role of matrix managers would lead to many positive, empowering changes. Oops.

The one thing that resonated was Godin’s criticism of half-hearted efforts: Do crappy PowerPoint presentations, because you don’t have the time or energy to do a good one. Do customer service that’s just good enough to keep a customer, rather than amazing customer service that makes a customer-for-life. Ship code that has bugs, but mostly works, because the ship date has arrived and you have to ship something.

Even so, I think Godin fails to recognize how institutionalized that sense of acceptable mediocrity can be. On my best days I can push back against cutting corners and accepting “close enough,” but not every day. On my worst days, I can only do the best I can for my own work. On the days in between, I choose my confrontations, and nibble around the edges, looking for improvement in small ways, and trying to persuade others to keep trying.

That’s the best I can do for now.

Is Junk E-mail Impeding Postal Mail?

Posted June 17, 2007 by Tom Comeau
Categories: Process Change, Software, STScI

I get 200-300 email messages a day in my three accounts, about two-thirds of them in my STScI (work) account.

On a recent day, the Institute junk mail filters caught just 21 messages, one of which was a false-positive. 39 other obvious spam, including several with a charming oversize image of a flayed penis, were not caught. Since the filters catch only a quarter to a third of my spam, and flags things that I thought were on my allowed senders list, I have to check them all.

The false positive is a puzzle: Bruce Schneier’s Crypto-Gram. *.SCHNEIER.COM was on my whitelist, but it seems Bruce switched the return address from MAIL.SCHNEIER.COM to simply SCHNEIER.COM at some point. Still, the message is long, but is all text with some embedded URLs. I don’t know why it’s marked as spam. I get a very similar daily summary from Northrop-Grumman of new JWST documents, but ngc.com has not (yet) been flagged as spam.

The effect, though, is that I have to scan the envelope information of all the spam messages, 60 to 80 a day, looking for false-positives. That’s almost half of my STScI mail, due to the combination of poor rules and a clunky, unreliable whitelist interface. Gmail is a completely different experience, with less total spam, and very rarely do I get a false positive. Better yet, telling Gmail that it guessed wrong (either way) is quick and easy.

What I find interesting is that I use the same technique for junk postal mail. I get 5 to 10 pieces of mail per day about 75% of it junk mail. I scan the envelopes, looking for obvious ads, but also for credit card, refinancing, and home equity loan offers. I discard (shred, actually) most envelopes without opening them. It would only be slightly more efficient to shred them directly into a recycle bin at the mailbox.

But I also get false positives. My mortgage company needed my signature on some paperwork to clarify the agency relationship for tax purposes. From my perspective, the envelope information on the tax-related documents looked the same as the envelope information for the refinance-offer-of-the-month. So I shredded it. Twice.

The first bit of good news is that I get very little porn (or near-porn, “male enhancement”) junk paper mail.

The second bit of good news is that there are things we can do (but don’t) to improve email filtering, like domain keys, authenticated from addresses, and improved blacklist and whitelist user interfaces. We don’t do those things, but we could.

I wonder if the overwhelming load of crap in electronic mail is causing me to look differently at paper mail, or if the overwhelming success of electronic direct mail advertising has increased the volume and sophistication of paper-based direct mail ads. Is my experience unusual? Have others thrown away non-junk paper mail because they are simply tired of plowing through junk mail?

Or is this just the reverse of the Al Gore thinking model: New ways of thinking about old technologies. That, at least, would be amusing.

Tim Wise followup: Implicit Preference?

Posted June 15, 2007 by Tom Comeau
Categories: Communication, STScI

Harvard University has a series of tests of implicit assumptions people make, under the aegis of Project Implicit.

I took a couple of the demo tests, the African American – European American IAT and the Gender – Science IAT. According to the tests, I have a slight automatic preference for black people over white people, and moderate association of male with science and female with liberal arts.

If you register and follow the link to the research side of the project, you get different tests. One of the ones I took was whether I have a preference for “lucky” people. For example, one guy got run over by a bus, while another won a car in a raffle. It turns out I have no preference.

I am occasionally amazed at how preferences develop, and how our unconscious, or at least unacknowledged, preferences affect the decisions we make and the assumptions we act on.

Upper middle class PTA leaders assume that the people around them grew up the same way they did, and it never occurs to them that one of their number grew up poor. We get something of a break on the religious issue, because there are enough Muslims, Jews and Bhuddists to avoid the automatic assumption that everyone is Christian, but they were shocked to find a Wiccan. (Atheists don’t even surprise even the most Christian among them.) They assume that, because they want to “protect” their daughter from information about sexuality so that she’ll wait until marriage, that I want the same thing, and am trying to provide the same “protection.” In fact, the most shocking thing I think I’ve ever said to another parent was that I hoped my daughter would learn a lot about sex, so that she could make her own choices. I hope she’ll wait until she’s old enough to know her own mind, but I would be surprised and concerned if she committed to a marriage with no experience at all. From the look on that mom’s face, you’d have thought I was pimping my daughter.

People do have preferences about who they like being around. We build “tribes” around common interests, both online and offline. I value diversity, and I also value shared goals and aspirations. Building those communities based on expressed preferences is healthy. Picking your associates based on your assumptions, particularly assumptions about skin color and gender isn’t tribalism, it’s racism and sexism.

I’m fortunate to have grown up in a racially mixed environment, and to have been exposed to both poverty and wealth. While I could have made different choices and gotten a better technical education, I think having a liberal arts background has made me a wider person.

So to torture the metaphor at the end of Tim Wise’s talk, I recognize the stinking pot of two-day-old gumbo, and I’m willing to help clean up. The problem is, I don’t think I know how to clean it. I’m inclined to throw it out, but I fear replacing the pot would be expensive, and dangerous.

So, watch the talk, and think about the problem. If you have ideas for how to clean the pot, I’d like to hear them.

Looking for Help on FOS

Posted June 14, 2007 by Tom Comeau
Categories: SEB, STScI, Webb Space Telescope

We are looking for help for the Flight Operations Subsystem team.

The position is posted internally now, but will be external any time. The ideal person would have experience with control center systems, ideally building one, and be experienced in working with developer, astronomer and system engineering communities here and at Goddard. This is work that Carl Biagetti is leading, and Carey Myers is starting to work on.

To quote me:

The JWST Flight Operations Subsystem Engineer will be responsible for refining the FOS operations concept, defining systems requirements, interfaces and architecture as well as supporting the development of FOS elements and their integration with the JWST Science and Operations Center. The FOS Systems Engineer will work under the direction of the STScI FOS Systems Engineering Lead as a member of a concurrent engineering team responsible for the FOS Ground System. This position will require interaction with JWST science, operations and development staff, the JWST NASA GSFC project, JWST contractors and representatives of other missions to achieve the work objectives.

Knowledge of the state of the art in satellite control center systems is required. This includes experience with the following: one or more NASA GSFC developed systems such as TPOCC, ITOS, ASSIST, HST CCS; one or more commercial systems such as EPOCH, ECLIPSE or OS/COMET; ground station and communications satellite interfaces; satellite command procedures languages; satellite control center operations procedures.

If you are somebody like that, or know somebody like that, I want to talk to you, even if you aren’t interested in doing this kind of work yourself. (For one thing, I can use help on the interview team!)

This is new stuff for us, so it’s a challenging, exciting opportunity.

Women like the work, but not the workplace.

Posted June 1, 2007 by Tom Comeau
Categories: GeekDad, Software

A while back I expressed surprise about girls being more effective than boys at a particular programming task. The more I learn, the less I’m surprised.

The problem, it seems, is not the conventional wisdom that girls don’t like math and science, and they just need to be encouraged to be interested in those things. The problem is that while girls and women do like those subjects, they don’t like the behaviors of people who work in those areas.

Debra Perlman, in eWeek a couple weeks ago, writes:

The vast majority of women working in the field of technology enjoy their jobs, finds the “Women in Technology 2007″ report published by WITI (Women in Technology International), a trade association, and Compel, a management consulting and research firm. Of the survey’s nearly 2,000 female respondents, 75 percent said that they would encourage other women to pursue similar interests.

Yet, female tech workers have mixed feelings about their companies’ climates, with only 52 percent believing that their organizations offer a favorable one for women.

So women do like the work, but they don’t like the workplace they see around them. Some of these behaviors are policy decisions. (Follow the link in the article for a couple of examples.)

Some are the result of discrimination, as I previously discussed, and as we saw from a couple of court cases this week. An important point, missed in some of the coverage of the Supreme Court case, is that a jury found salary discrimination did exist at Goodyear, but The Court found the claim was barred by the plain language of the law. The GE Transportation case will not suffer from that defect.

Next week at the Institute we’ll also have some discussions around behavior, which we’ve known since the 2000 employee survey is a problem. Women get ignored, their input is not solicited, and their achievements are not recognized.

That shouldn’t happen either.
