herdrick··on Your body wasn’t built to last: a lesson from human mortality rates
Can you point to some great artists and writers who studied art history or literature? I agree that formal study and practice of music (not the same as studying music history btw) has lead to a lot of great music.
herdrick··on Your body wasn’t built to last: a lesson from human mortality rates
Studying art and literature isn't the same as creating it.
herdrick··on Uncloaking a Slumlord Conspiracy with Social Network Analysis
Was that the best Frontline ever or what? Thanks.
herdrick··on Dropping a Magnet Through a Copper Pipe
Yes. You could expect it to bounce off the walls of the pipe, though.
herdrick··on Google can be used as a graphic calculator
thanks!
herdrick··on Google can be used as a graphic calculator
that's it, thanks
herdrick··on Google can be used as a graphic calculator
Anyone know how to denote 'log base 2'? This: "log (x)" assumes base 10.
herdrick··on You'll be dead soon - Carpe Diem
I wonder what the product / prototype was.
herdrick··on Am I the only one that thinks TDD is really antithetical to agile development?
Of course not. Most startups avoid TDD.

More generally, trust your gut, especially when people start talking about Methodologies. Your instincts are good.

herdrick··on The King of Human Error
Wow. I was going to disagree with you... then I read the quiz and note. It's worse than a mere error, the quiz writer is willfully throwing away knowledge about the world.

They didn't give conditional probabilities but of course we can, and should, use what we know about the world to make guesses at P(E|'likes math'), or at least whether that's greater than P(L|'likes math'). It surely is and you can do something similar with carpentry and an apolitical nature.

It's true that even with the assumptions I've given above you can't come up with a precise answer - none of the choices are any good - you can certainly say that "...the correct response being precisely 30 percent" is thoroughly wrong.

herdrick··on Apple's Supply Chain Secret
I read in the 90s that Microsoft's suppliers appreciated that MS never went the 'net 30' or 'net 90' route like other Fortune 500 corps and just paid as soon as they got the bill.

Where are the news reports of this incident?
herdrick··on Steve's Google Platform rant
AWS was pirate operation

That's amazing to me. I thought such things were never done in software anymore because: why not leave the company and do the same thing in your own startup? Same hard work, high risk, etc, but with giant upside. Was it because of something wrong with Seattle's startup culture?

herdrick··on "Unknown or expired link." - Why?
Please don't call people or their work 'moronic' (or the like) here.
herdrick··on The elevator pitch of failure (how and why I simplify when asked why we failed)
This was really great. Thanks.
herdrick··on I develop free software because of CUNY and Blackboard
What is Blackboard?
herdrick··on Steve Jobs’ Personality is Integral to Apple
I admire Steve deeply. But in this post you see what was probably the worst thing about him: people feared the guy. Maybe that's unavoidable if you have high standards - I'd really like to know. But I don't think this is a case of fearing his high standards, just fearing an ordinary "That's stupid" reaction.

I only mention this because I think a lot of us here want very much to be like Steve. We need to work to avoid imitating the wrong things.

herdrick··on The College For-Profits Should Fear
The key paragraph:

"WGU’s answer to the status quo is to offer a degree that is based on competency rather than time. By gathering information from employers, industry experts, and academics, Western Governors formulates a detailed, institution- wide sense of what every graduate of a given degree program needs to know. Then they work backward from there, defining what every student who has taken a given course needs to know. As they go, they design assessments—tests—of all those competencies. “Essentially,” says Kevin Kinser, a professor of education at the State University of New York at Albany, “they’re creating a bar exam for each point along the way that leads to a degree.”"

herdrick··on The Decline of Unfettered Research (1995)
I recommend the Readability bookmarklet.
herdrick··on Ruby in any input field. Meet Yoke - (Python, Bash, Perl, PHP supported too).
When you install for Python you need to make the keyboard shortcut yourself, but I don't see an app to invoke. Is there something installed (in /usr/local/bin ?) that I can execute?
herdrick··on Physicist cuts plane boarding time in half
I don't think you'd call this a Monte Carlo simulation. It's just an experiment.
herdrick··on Aaronsw indicted for hacking MIT network to download millions of JSTOR docs
Thanks for the dissenting opinion.

Is this worse than the sort of thing that goes on in the early days of most startups, including our most revered? People around here have a lot of respect for pg, rtm, tlb and their startup Viaweb - go back to "Founders at Work" and read how they got computer time needed to get the startup going. That kind of thing is practically universal in startups. The good ones, anyway.

So Aaron appears to have cut some corners in getting an interesting project off the ground. Slap him on the wrist.

herdrick··on Python idioms
You don't need a macro to do that in a lisp. Typically you just use a built in 'partial' function, which just makes a closure that will call the original function. (It's simple, so you can just make your own if you're using a lisp without it built in.)
herdrick··on Mistakes You Can’t Afford to Make with Stock Options
I only bring it up because a lot of people do "try to stick it through to an exit" only due to that bias. It's a sad waste of talent.

EDIT: In fact, I think that whole section should say the opposite: "2. Refusing to quit with unexercised options"

herdrick··on Mistakes You Can’t Afford to Make with Stock Options
Very good post, aside from this: "So if you join a startup and don’t exercise, you should probably try to stick it through to an exit." No. If you're thinking of quitting, presumably an exit which will make you rich is not imminent. Hanging on to a job when you have better alternatives elsewhere so as not to lose the possible value of your options usually is a tragic case of the 'endowment effect' bias in action.
herdrick··on Storm - the Hadoop of realtime processing
OK, thanks! That's valuable info.
herdrick··on Storm - the Hadoop of realtime processing
Nathan, we'd love to hear your postmortem on BackType's experience with Neo4J, and how Sphinx is turning out.
herdrick··on Storm - the Hadoop of realtime processing
Ah yes, I should have read not scanned "3. Distributed RPC". Thanks.
herdrick··on Storm - the Hadoop of realtime processing
This sounds great.

This is the traditional realtime processing use case: process messages and update a variety of databases.

Question: I typically think of real-time as a need for user-facing things, i.e. handling a user's requests before he gets bored and goes away. Is Storm set up for that? Or is it mostly meant to update a database with results rather than return them to a waiting process?

herdrick··on WWU: Computer science department needs to step up to the future
Riordan said the computer science department could be doing more... in terms of forging ties with technology leaders...

It's funny, WWU CS has a repuation for being a very pro-Microsoft department. Not sure what's really going on here.
