blink(16) prototype is woody and awesome
[originally posted on ThingM blog] A few days ago ThingM friend Rusty, operator of the wonderful SomaFM, wondered if there would ever be a “blink(16)”: a blink(1) with a 4×4 grid of LEDs. Well it turns out that due to a secret feature of all blink(1) mk2s, it’s actually pretty easy to make, if you have [...]

Back in "business"
Just returned from my vacation in Paris. Hotel de Crillon was closed for renovations, Ritz had limited availability also due to renovation, so I had to settle for The Peninsula ;)
Here are a few impressions and observations, while still fresh.
Here are a few impressions and observations, while still fresh.
- taxis only take cash; ride from the airport to Paris center is about 60 euro and takes about 50 minutes;
- the lowest cost Starbucks coffee is twice more expensive than here, at about $4.5 (3 euro), but still a lot cheaper than the "cafe creme" at Les Deux Magots or Cafe de Flore;
- cheques are still used for grocery shopping (!);
- the fixed air conditioning units (installed outside the windows) are probably not allowed, since they would really spoil the beauty of the buildings; posters are also forbidden, though I saw some "pixel art" placed high (that is, hard to remove) on some buildings;
- one can actually live on and retire from a job as waiter or hotel concierge;
- tipping in restaurants or for services is not a habit;
- selling padlocks around famous places is big business;
- Lacoste has a "lab" which also makes beautiful bicycles (this may be of interest to Justin :)
- great Star Wars animatronics in DisneyLand Paris;
- charging stations for electric cars;
- and finally, a (probably expensive) clock :)
