Glad you're enjoying the program. Glidebook is really experimental at this point. Although I use it myself for all of my logging activity, it's incomplete in various ways and isn't intended for public consumption yet. If you're able to get some good use out of it, great! Some sort of import functionality is an obvious thing to have, but it doesn't exist at the moment. Are you a programmer at all? I guess that you must have some skill i....

Mike I downloaded your "Logbook". Great job. Much better than my feeble attempt. Question: How can I import aa CSV file into your logbook? I have almost 400 flights in my excel spreadsheet and I would hate to re-type this into the logbook. Bob

I’ve had some of my most intense music experiences in this place, often while working out. (Anyone else had similar experiences at high altitude?) Just got back from my daily workout in the darkened aerie above the gymnasium where they were playing the U2 concert film “Live in Paris: The Joshua Tree.” Songs from The Unforgettable Fire taking me straight back to freshman year, 1985: friendships and first loves… my incense-filled room ac....

Despite the morning’s wind and low visibility, colleague Joanna just arrived from Berkeley hand-carrying some cables and a special surprise from Jerry at LBNL, carefully packaged in anti-static plastic and bubble wrap. It’s the printed circuit board from one of our Digital Optical Modules, one which failed visual inspection and is therefore scrap for engineering purposes. I.e., a nice, flat, attractive paperweight. I’m touched, particula....

It’s 10:05 AM and getting close to bed time. The weather today is strange – quite warm (almost minus 10F) but with 21 knot winds, making the wind chill about 50 below. The snow is blowing high and visibility is poor at times. But it’s quite beautiful. Life is settling down into a routine, of sorts. Wake up as late as possible, usually before dinner. Clean up room, go to gym, meditate, have breakfast. Start work when satellite rises aroun....

This post was taken from a Mahalo Answers Question I answered. I thought rather then risk Mahalo going away (since Jason Calacanis has said hes working on something else) I thought I would copy it here. Question How will a Athlon 64 PC with 512 of ram hold up as a home server. Whats the best setup… read details. I want to setup a drag and drop file server as well as a voip server like teamspeak. Also have a low user website. What O..

In the next few days, the last few 'Cubers are arriving on Station to help us with end-of-season commissioning of the new strings. Many more IceCube people are leaving, however… most of them drillers. It will be nice to be here when things are a bit quieter. The winter-overs are already talking about how great it will be when we summer folk are gone. Some people pay a fair chunk of change to fly here for an hour or two, look around, and ....

You know - most technologies change drastically over time. As a result, I got my hands on an old BlackBerry 950 model from 1998 (the 850/950 series were the original BlackBerry smartphones on the 800/900 MHz Mobitex networks, respectively). The problem is this: It really hasn’t changed that much. Aside from the color and graphics, the BlackBerry 950 running BlackBerry Device Software 2.5 had pretty much the same applications and functi..

Primary keys only need to be unique; there's many characteristics they often have but don't need to have

There is often a misunderstanding about primary keys in database tables. Primary keys identify rows uniquely, so the only property they have to obey is they must be unique . Primary keys don’t have to be numbers. But if they are, here are a few properties these numbers don’t have to have: Numerical PKs don't indicate ordering, i.e. which row was inserted first. Looking at the highest PK value doesn't indicate the number of ro..

The Beineke Rare Book & Manuscript Library at Yale is blogging a word a day from Samuel Johnson’s seminal A Dictionary of the English Language . Their selections are so far tending toward the obscure (i.e. bandog ), and include great photos of the book and many handwritten additions and corrections. I wonder how many of these words were actually in common usage in 1755, especially those where Shakespeare is given as the only reference..

I think my previous excitement was unfounded … probably was just some guy playing around, not a real bot… But I’m patient.

It’s amazing that the following all works: Using my terminal program ( PuTTY on Windows, set to UTF-8) connected to a Linux computer (terminal settings set to UTF-8), created a file whose name had various Unicode characters The shell allowed me to type those characters (vi ) The standard programs such as "ls", "cat", "vi" seemed to be able to handle these file names I checked the file into the Subversion version control sy..

There was a question about PRECOMPUTE_SUBQUERY hint in an Oracle Forums thread . Here I will post the answer I gave there and also elaborate it more as it explains a little known interesting fact about Oracle cursor management. Also it allows me to introduce few advanced Oracle troubleshooting scripts by example. This is a fairly long post, but if you are interested in some Oracle cursor management and SQL execution internals, keep on re....

An Email Address Field Should Be Called "email address" (Not "email")

Naming is extremely important in software development. Any software that deals with emails probably also deals with email addresses. Emails and email addresses are two completely different types of objects, with a completely different set of attributes, and a completely different set of actions which one can perform on them. Even if your application only deals with the one or the other type, it would be unwise to confuse them.

Lsof (list open files) is a really useful tool for troubleshooting open file decriptors which prevent a deleted file from being released or a shared memory segment from being removed.

My room in the A4 wing of the Elevated Station Been here about 58 hours so far and the reason I am counting in hours instead of days is that my sense of days is pretty shot. I have a screwy sleep routine: 10 hours awake, 3 hours asleep. Lather, rinse repeat. I am trying to be up at night (we keep New Zealand time here) for the satellite hours but usually that entails a long nap in the middle, which curtails my sleep during the day. I’ll....
