ry comparing news feeds from CNN against those from the BBC. I am subscribed to various feeds from both and in CNN no descriptions are bound to the titles. Why even syndicate if the subscriber gets 2-word provocative titles? The BBC is different, possibly because it has no commercial interests. It also opened its news API to the public recently, which was inarguably a wise step.

The ‘greedy feed’ attitude will possibly change due to Google’s embedment of adverts in feeds. This, in turn, is likely to set a precedent and motivate competitors (e.g. Overture) to do likewise. The official Google Factory Tour includes a preview of AdSense in feeds; see the picture at the bottom-right corner of the page.

The BBC published an article about a model which solves the “I’m my own Grandpa” paradox in the context of time travel. The model is based on laws of quantum mechanics.

Researchers speculate that time travel can occur within a kind of feedback loop where backwards movement is possible, but only in a way that is “complementary” to the present.

In other words, you can pop back in time and have a look around, but you cannot do anything that will alter the present you left behind…

Some months ago, an automatic and effective way of obtaining music was described: no need to run any heavy graphical program; no need to select music (only sources of music of the desired genre); no limits on bandwidth or volume.

Taking this further, Dr. Scott Tobkes explains about his method of bringing commericals to a halt.

Something I’ve had fun doing lately is recording live of archived streaming audio from radio stations around the country

There are innumerable subjects and programs. I record it to mp3 or wav, and listen in my car or PC, while fast-forwarding through the commercials. I know that there are aggregators that will make this a seamless process like Ipodder.

I don’t like to call them podcasts. I use this program…

It wasn’t long ago that the Internet Archive was mentioned. This amazing, non-profit resource has been storing snapshots of the Web since 1996. It is now revealed that the entire system is Linux-powered. It can hold over a petabyte (1000,000 gigabytes) in volume and yet remain affordable.

here is a great deal of talk about AJAX recently. It is the new branch of development which makes real-time interaction possible. To take examples from Google, GMaps allow movement around the map without the reloading of a page; Google Suggest fetches possible completions from the server in real-time; GMail is another AJAX-rich Web application. The main advantage of this technology is that it one does not need to refresh entire pages, but just modify little bits whenever required.

There are simple ways of indicating change and increasing usability. The lastest release of the Horde project, for example, has plenty of subtle feedback for interaction. A few instances: the pointer changes to a finger when unfolding menus, “+” changes to a “-” and vice versa; Hovering will result in different background colours to indicate severity.

There are some very nice demos in the Open Source library named Rico. I was impressed at first, but I soon spotted a major drawback. The pages devour signals so mouse gestures, for instance, begin to misbehave. Also, browser compatibility is limited, which makes pages like that a bad choice for practical purposes. Another example of flexible designs shows the great powers of modern browsers.

There has recently been some gossip about Google’s project which involves 3D maps of San Francisco, as well as other cities. More details have been disclosed today (Kudos to Slashdot) including some pictures and related research papers (PDF).

An example of output maps, which can be generated by trucks with laser tracers

Polaroid-o-nizer applies a sequence of transformations and adds effects which create fancy images on-line. There is a simple yet flexible Web interface which enables you to customiseoutput images.

Let us put the famous Lenna to the test, as was done some months ago with the image-to-text transformer. Below is the result.
