 I'd really need to hear the real conversations to know what's up.
 But the answer to the first contractor question probably ought to
 be:

    Adding one contractor will slow us down for 45 to 60 days, then it
    will add X percent to our speed.

 The answer to the second is probably something like:

    There is no such number. We can't vacuum your office in ten
    seconds by using a thousand cleaners. They won't fit in the room.

Sick of smoke!   30 Jan 06
[print link all ]
As my girl-friend is allergic against smoke, going to restaurants in Germany can be a pain, as most restaurants do not yet have non smoking areas. I am jealous of Italy in that respect, where smoking is simply banned in all public spaces.

To make our life easier, I invested 5 hours to setup a simple website to build a database of nonsmoking restaurants. It is a simple rails application.

Help to fill the database.

Why is rails so successful?   20 Dec 05

Interesting blog-entry by Ryan Ripley.

Rails is such a success as it has a strong story, good timing, wentviral, and is authentic.

Ruby/Amazon   19 Dec 05
[print link all ]
Ruby/Amazon is a Ruby language library that allows programmatic access to the popular Amazon Web site via the REST (XML over HTTP) based Amazon Web Services. In addition to the original amazon.com site, the amazon.co.uk, amazon.de, amazon.fr, amazon.ca and amazon.co.jp properties are also supported.

Although the library is still in development, it already provides support for the vast majority of the AWS v3.1 API. For example, all forms of product search are implemented, along with the transaction details API and the remote shopping-cart API.

Ruby/Amazon also offers advanced features not directly available via the AWS API, such as the ability to retrieve all results pages for a particular search, rather than having to deal with AWS responses of 10 results per page. Ruby/Amazon will even use parallel threads to improve the performance of such multi-page searches.

Another advanced feature is the ability to cache responses returned by AWS. If the cache is used (as it is by default), the results of each unique query will be cached and used for 24 hours. The cache can be manually flushed of all or just the expired entries.

One other useful advanced feature is the ability to determine the appropriate Amazon locale for a client, based on its IP address or hostname. This allows you to direct AWS operations to be performed within the correct geographical Amazon site for the given client. German clients can be made to operate within amazon.de, British clients sent to amazon.co.uk, etc.

More features are planned for future versions, such as Amazon Web Services for Sellers. See the TODO file included with the software.

The easiest way to get started is to click on the Amazon class and to follow the examples.

The probabilistic age   19 Dec 05

Q: Why are people so uncomfortable with Wikipedia? And Google? And, well, that whole blog thing?

A: Because these systems operate on the alien logic of probabilistic statistics, which sacrifices perfection at the microscale for optimization at the macroscale. Great read
