"Get Your Hands Dirty with BGP" tutorial at next month's RIPE meeting

At the RIPE-70 meeting next month in Amsterdam I'll be doing a tutorial on BGP: "Get Your Hands Dirty with BGP".

This is the "light" version of the regular BGP training that I do several times a year: the theory part will be around 30 minutes and then about two hours of hands-on BGP using the Quagga routing software running in a virtual machine on the participant's laptops.

If you're attending the RIPE meeting and you're interested in participating, please go to this page and send me an email so I know how many people to expect.

→ Keynote '09: Connecting Objects with an Adjustable Line

I honestly thought I knew pretty much everything there is to know about Apple's Keynote presentation program. I was wrong. I didn't know this:

When you want to join two objects with a line, the easiest way to do it is to use a connection line (rather than creating a separate line as a shape). Two objects joined by a connection line remain joined even if you reposition the objects on the slide canvas.

C.G.P. Grey's RSS feed

CGP Grey videos are now available in convenient video podcast form.

This is great. I love his videos, but hunting them down on Youtube is just too much work these days. With a podcast, watching/listening episodes in order (well, once you turn off all of this "newest on top" nonsense) is easy and new episodes automatically pop up. Youtube, on the other hand, seems to go out of its way to make it difficult to watch stuff in order and quickly find new stuff. Apparently, they really need you to go with the flow and just watch whatever video they feel should be next.

This is the link to the RSS feed and this the link on iTunes. Too bad the feed currently only has a single episode.

The Dell P2415Q fits 2.5 pages of A4

After yesterday's post about the Dell P2415Q monitor, I wondered how many sheets of A4 paper fit on the screen. Answer: height-wise, it's a perfect match:

At 52 cm, you can fit almost 2.5 sheets side-by-side. Interestingly, Apple's Preview application (middle) knows the size of the screen, and PDFs zoomed to 100% are exactly the right size. Unfortunately, due to the menu bar, the title bar and toolbar, the A4 PDF won't completely fit on the screen and in full screen mode Preview zooms to 98%.

Pages (left) and Word, on the other hand, still operate under the delusion that screens have a resolution of 72 pixels/points per inch, and need to be set to about 130% zoom.
