What’s up in research?

After playing for a little while, view
I managed to connect my Macbook Pro to the internet using my mobile phone via bluetooth. I have a small Samsung ZV10 and my service provider is Vodafone New Zealand. The steps are quite simple:

  • Click the bluetooth icon in the topbar and select ‘setup bluetooth device…’.
  • Check that the phone is running bluetooth and that is discoverable (Under settings, practitioner
    connectivity).
  • Select mobile phone in the list of available devices.
  • The computer will search and—we hope—find your mobile phone.
  • The computer will generate a numeric passkey that has to be keyed in and accepted in the phone.
  • Select ‘Access the Internet with your phone’s data connection’ in the next menu.
  • The settings to connect to Vodafone in New Zealand are:
    • username: vodafone.
    • password: vodafone.
    • GPRS CID string: *99#
    • Modem script: Vodafone VC701SI

This explanation is based on the excellent—and illustrated—version by Pukupi.

I have been settling on my final software selection:

  • Quicksilver: which is a great launcher and keeps learning about my preferences. Additional plugins installed: del.icio.us, help dictionary, firefox and iphoto.
  • Office: well, I do exchange a lot of documents with colleagues and friends that use the Windows version. In general works quite well, although compatibility is not perfect. My main issues have been spreadsheets containing lots of VBA or embedded Activex controls and compressed graphics in PowerPoint, which show that puzzling ‘QuickTime and a TIFF/JPEG decompressor are required to view this picture’ message. In addition, Microsoft has not released a Universal binary for Office, and will not do it until they have the next version available, whenever that is.
  • Thunderbird: after trying Mail.app and Entourage, my experience was disappointment with how unreliable Mail.app was (missing emails and crappy IMAP support) and found Entourage too big and clunky.
  • Firefox and Camino: Firefox is a great browser, but it feels a bit un-Macintosh. Camino uses the same engine, but with a nicer interface. I like the ability of closing the tabs just next to their names (a la Safari). However, it does not have (yet) incremental search, which is something that I love in Firefox (PS 2006-06-29. It is possible to have a close button in the tabs of Firefox through the use of the Tab X add-on. PS 2006-06-30. Bob Cantoni points out ‘to close Firefox tabs, just middle-click on the tab to close it; i.e., click the scroll wheel’).
  • R: a great cross-platform (and free) statistical software. I do most exploratory analysis using it, and only go to SAS, using Parallels (see below), when strictly necessary for working with other people.
  • Parallels: allows running windows and I currently use it only to run SAS. It still feels a bit slow, but for writing and prototyping SAS code is good enough. I bought the pre-release copy at US$50.
  • Copywrite: I normally become very easily distracted when using a word processor to write. All the options, fonts and formats become a real nightmare. Enter Copywrite, which is a simple writer’s editor. It allows only basic formatting, so it is very good for the first couple of drafts.
  • Devonthink: after reading Merlin Mann’s comment on 43 folders, I decided to give it a try. I am quite tempted to use it in a continuous basis. It is a good brain dump, where I can put all odds and ends that I normally loose. The current version still has some bugs and missing features, like that the full screen editor works only for plain text and that changing the colours of text may have effects on other parts of the program. Anyway, searching and connecting notes seems to work quite well. I still think that Copywrite’s full screen editor is much better and less distractive. PS 2006-06-30: I have decided to wait until the next version before buying Devonthink: still too buggy for my taste.
  • Writeroom: I just started testing this great full screen writing system. Just write there, no need to save. If I want something a bit more complex, I can type using Markdown and convert it to HTML using Humane.Text service. PS 2006-06-30. Jers Novel Writer is another writing program that supports full screen mode and that deserves a try.
  • TeXShop a highly polished LaTeX distribution, that I am using for writing lectures notes for STAT220 (Biometry I).

Sharing printers in a mixed network

I can not remember another time when I have been using so many computers in such a regular basis. My main work machine is Mastropiero1 (Macbook Pro 15”), although there is an exception for simulation work, where I use Nutcracker (a.k.a. Black Box, a generic 3GHz, Windows XP machine, which just happens not to be beige). In addition, at home I also use Happy Meal2, a Power PC Mac Mini that acts as back up and has the printer connected. Last—and certainly least—I keep Beige Box (a generic 1GHz Windows XP machine) still functional at home, just in case we need some extra simulation capability when time is not an issue.

Last weekend, we bought another cheap windows laptop for Plus Tree, our consulting arm. It is a Compaq Presario V2000, temporarily named Lucrezia Borgia3.

Given that the printer is attached to Happy Meal and that we some times need to access it from either Mastropiero or Lucrezia Borgia using wi-fi, we:

  • Shared the printer (using System Preferences, Sharing), which works for any Mac computer in the network, including Mastropiero.
  • Allowed access from Windows machines—like Lucrezia Borgia—installing Bonjour for Windows, which has a handy ‘Bonjour Printer Wizard’. Use the Wizard and the printer is now available to Windows too. Piece of cake!

Incidentally, after using the Compaq laptop for a while, I can say that it feels as warm as the Macbook Pro on the top surface. The exception is the part above the function keys in the MBP, which is bloody hot.

P.S. 2006-06-30. Welcome to 43 folders’ readers. Five hundred visits in two days; not bad for a small sidebar link.

It has been a log time without writing about research. New country, click new city, unhealthy new job. In addition, thumb
consulting and professional service. Last but not least, family and friends come first: the end result is very little time to blog and even less for writing about research.

So, what am I doing at the moment? Simple, trying to figure out areas where I am not hitting diminishing returns too quickly. For example, estimating two hundred variance components is too rich, if we can do the job with ten. The practical return from all the additional works tends to zero: we are not making much of a difference. So, what’s the point? Yes, I can publish that, but who cares?

From a practical point of view, the real issue for me is on what is affecting competitiveness in a big way. Forestry is a long term endeavour, and the longer the rotation the higher the risk. From that point of view, extending rotation because radiata pine wood quality is not good enough borders on the stupid. Doh, of course is crappy wood; answers:

  1. Use something else or is there life beyond radiata pine?
  2. Select and breed for trees that have decent (I do not mean good) quality.

So, what are my current obsessions?

  • Profitable shorter rotations. What are the limiting factors (hint: crappy wood quality, small size pieces and scale of the operations) to make this happen?.
  • Very early selection of adequate trees. Notice emphasis: selection does not to be perfect to be useful. Adequate selections at age two is much better than good selections at age ten years.
  • Why do trees grow the way they do in wood properties? Why do trees choose different strategies that have such dramatic differences in wood quality?
  • Rapid turn-over breeding strategies. Are we still taking fifteen years for a breeding cycle? It is 2006! Can’t we do any better?

There is an obvious quantitative void in my obsessions, I know. But I am going back to attempting to understand some basic processes before I embark in more number cruncing. Despite of this, I am also interested (but not obsessed) in the following problems:

  • Simulation of breeding strategies. I have a project working on this topic starting in October this year.
  • Mate allocation and population structure. Trying to show that we can get rid of sublines and other artificial groupings when using sensible mating policies.
  • Large scale genetic evaluation: how simple is simple enough? My way to help having frequent genetic evaluations.

What else? I am involved in a couple of three projects with students, dealing with wood quality, breeding or both. I have a new Ph.D. student starting in August on the interaction of economics and breeding. Ah, I almost forgot: there is a large number of lectures coming my way, better look busy…
