christofd··on Interactive course to explore Chrome DevTools
nicely done! very helpful intro.
christofd··on Official Hacker News T-Shirt
nice and subtle :)
christofd··on Bill Gates Says There Is Something Perverse In College Ratings
That explains a lot actually. Powerful and simple explanation for the world we live in. However, pretty much the opposite of the so-called "trickle-down" mechanism... more like "trickle-up".
christofd··on Don’t worry, Europe: you’re about to get a new beginning
Well said. This matches my experience living for a long time in Germany (south and north), and interactions with French. I remember (from friends) the problems at DLR in Munich (German Aerospace Center) with senior French engineers trying to pull rank, which doesn't work in team-based German work culture.

Also, spot on with Anglo news coverage not really speaking for/ capturing the essence in continental Europe. E.g. current Anglo news criticizing northern European countries for 'austerity' measures (well, it's their money, so obviously they will not hand it out gladly).

It's an elusive topic with hardly any good information. Quite unusual to see such a balanced reply here.

christofd··on Apple's tribute to Steve Jobs, one year on.
Pierre Fournier does a super smooth rendering of all the suites... he's like a French machine, technically perfect & soulful interpretation. especially the 6th preludium is a joy to hear as he climbs up the stairway.

yeah, Casals is the man. don't like rostropovich rendition IMHO.

currently playing those Suites on a Carbon Fiber Luis & Clark instrument - luisandclark.com

christofd··on Wolfram Alpha Personal Analytics for Facebook
Yeah, stuff with a scientific bend doesn't get shared, although it has impact. It creates its own niche, with considerably less noise.

Sorry to broaden the scope, but this made me think...

In stock markets, you have the concept of "noise traders", less well-informed traders. They sort of create their own dynamics, sometimes even generating good return on investments, where better informed traders stay out of the market.

Social dynamics... not sure if it's possible to derive some new fundamental laws, because human behavior is too fluid. Maybe in the end (after years of "big data" number crunching) all we get is some empirical observations and weak correlations.

christofd··on Wolfram Alpha Personal Analytics for Facebook
Wow. That's impressive. Big step forward in social analytics.
christofd··on The effect of typefaces on credibility
regarding comic sans use at CERN... often found that scientists like hideous designs. it's a way of saying that we work on serious stuff.

a lot of sites at MIT, CMU have that mark... the more prestigious, the uglier.

of course it has to be a certain style of ugly.

christofd··on Canada’s vanishing tech sector
agreed. been looking at this for a while. If you're Canada based you gotta reach out internationally (Europe, U.S., Asia) to acquire funds, projects, ideas. Thinking domestic is not optimal.
christofd··on Famous judge spikes Apple-Google case, calls patent system “dysfunctional”
well, this was 30 years in the making...
christofd··on Piccsy Pitchdeck
alarms were going off when I read "pitch deck"...
christofd··on Poll: HN Meetup in Munich, Germany
same here, now in Toronto.
christofd··on Can we kill the music business too?
great wall of text! you have a weblog or so? interested in the intersection of technology and cultural stuff as well... i'm based in toronto, btw. quite often in nyc. cheers.
christofd··on I Have No Talent
Great advice. My Dad always told me I suck at music. But I just wouldn't give up. I destroyed one Cello bow along the way in frustration for my lacking skill, but now 20 years later I got this beast under control.

Then, of course, there are the people that are hopeless, and no amount of practice will get them over the hill.

christofd··on Poll: Hackers, do you play any musical instruments?
Cello, turntables (vinyl and a digital system like Serato), dabble a little on piano, sang in a choir
christofd··on Why do people pay for webapps?
Good list.
christofd··on Why programming and musical talent go together: enjoying seeing patterns
Yeah, I play strings and I hated that scene. You can even deduce from this scene that Depardieu hasn't learned to play any type of instrument, which can be said for a lot of Hollywood actors faking it on camera.

Although, there is the rare breed of actor that plays an instrument.

christofd··on Boost your productivity with Hemingway’s hack
A rough assessment - needs some more thought:

Exactly. This advice might apply more to a creative process, where original thought counts above all else. I imagine being truly creative is an exhausting activity, knowing several professional artists (oil paint). You're basically holding a large set of options simultaneously in your head and try to make unique connections between them. The value is not in how many iterations of connections you go through, but coming up with something unique at all.

Development strikes me more similar to solving cross-word puzzles, or playing mine-sweeper, where activity is more guided, focused along a smaller set of options, with lots of trial and error in the process: it's sort of "focused play"/ experimentation. Here it seems more valuable IMHO to keep on going once you're in the flow. You're not looking for that one special connection, that will make your day, but are solving many little problems that aggregate over time.

I could imagine science-based development work to be creatively exhausting as well, where you're trying to prove some theorem etc. Hemingway's advice might apply itself nicely in this case.

I'd like to see more blog posts on how to solve different types of problems. E.g. I know that walking away from a hard problem after you're exhausted works out well (the subconscious keeps on working on it), or as Hemingway proposes, walking away right before you become exhausted.

My two cents.

christofd··on Predictions for 2010
Ah, good to know :)
christofd··on Predictions for 2010
Not sure this is correct procedure, exposing the privacy of a HN fellow. I personally would have second thoughts posting that.
christofd··on The decline of the MBA will cut off the supply of bullshit
Hmmm... you might be right. Business people, representing capital owners in a world with increasing capital concentration, exert a lot of leverage. Leverage pays well.
christofd··on The decline of the MBA will cut off the supply of bullshit
Seconded. BS becomes official. (Dilbert doesn't count; The Economist has to say it)
christofd··on Getting things done by procrastinating
Yes! How to cure the fear of the blank page. One of the first articles that I've found how to deal with this problem.

You can't break procrastination head-on. It's gotta be tricked to defeat it.

christofd··on Semantic Versioning - A technique for avoiding "dependency hell"
Interesting idea. I could imagine whole environments of development stacks being defined: e.g. a Rails 2.3.5 production stack, or a Django stack, or a Clojure webdev/ data mining stack, and all according to exact version numbers.

I could see that for Big Ticket projects such as Rails/ Clojure/ Django etc. people would maintain an up-to-date 'semver' database.

The only thing is that the name 'semantic' is not really a winner (it sets people on edge). Maybe something else will survive in the end, unless people are comfortable enough with the pragmatic value of the idea and will look past the name.

christofd··on How Facebook Is Making Friending Obsolete
Interesting. I'd second that. More to come.
christofd··on Erlang Creator Joe Armstrong Wants to Ditch AJAX, Loves Chrome's New Web Sockets
Something new to play with. Joe hits the sweet spot, regarding powerful & pragmatic, again.

Websockets + Erlang... nice.

christofd··on Wattvision (YC W09) Shows The Power Of Simple, Realtime Energy Monitoring
Very nice seamless implementation: device, connection, web-based, iphone. Full circle. Very professional. Great Name.
christofd··on Are You a Guitar Player or a Club Owner?
I actually value the notion to try to attach a metric to a fuzzy term like 'happiness', even though it doesn't work. At least it displays the will to measure everything.

Edit: happiness = serotonin level in spinal fluid. Suicide cases show low levels after autopsy.

christofd··on New Ruby on Rails Tutorial book-in-progress
e.g. I fondly recall the use of the 'Haversine formula' (calc. distance on a sphere with given lat, lng) built in SQL, instead of using one of the available Geo ruby libraries/ gems (although I'm not sure, if those gems were available back in 07).
christofd··on New Ruby on Rails Tutorial book-in-progress
Really like Michael's clear writing style (remember reading Railsspace back in 07). Thx for this new resource.

Also like the fact that he doesn't use many gems, but discusses building stuff from scratch (regarding Railsspace book).
