plane stuff

Test flew my RC plane with camera mounted in it today, was fine. Balance good, weight not too bad, added power draw seemed OK, etc. Didn't have the receiver for the camera, though, so I don't have any video footage of it.

The main thing left to fix is that when the motor is on, the power gets so noisy that the camera starts fucking up. So after researching online, I've decided to go to Radio Shack in the morning and buy the appropriate resistors and capacitors (well, just one of each really), and build a lowpass filter. Judging by how the video looks when the noise is there, it appears to be correlated to the speed of the motor (the motor probably spins at upwards of 2000 RPM), so it seems relatively easy to build, say, a 30Hz lowpass (which using a 2.2 ohm resistor and 2200microfarad cap will give me a (workable) voltage drop of 0.2 volts, at 80mA load), which will hopefully take care of it. I'll buy some variety of resistors and capacitors to tweak the filter once I see how it works, too. Fun fun, math meeting electronics, mmm. I'm not sure what the frequency response curve is for a lowpass like this, so I'm shooting really low. Anybody have any experience with doing this? :) I guess I'll find out if I'm completely wrong...

(Perhaps Obvious) Thoughts On Being an Individual Software Developer

Part I - Choosing a License

Disclaimer: I am not a lawyer, these are my thoughts as a software developer.

For me, there are three basic licenses I consider when I'm releasing a piece of software.

1. A Proprietary License

This often seems like a safe first step--keep the source code to yourself, let people use binaries, etc. I'm not aware of any "standard" closed-source licenses one can use (are there any?). So it seems a lot of people end up copying other peoples (expensively crufted) legal text, which may or may not be that good, and raises copyright questions for the license itself.

At any rate, releasing software with a proprietary license has benefits, especially since you can completely monopolize the software, giving you potentially more opportunities. You can always open source it later, too.

The drawbacks to keeping source private are obvious, though. You can't get people to work for you for free! (See Part II, below)

2. General Public License (GPL)

When I want to open source my software, and also want to ensure that any derived versions of my software remain open source, I'll usually choose to use the GPL.

Contrary to what many people seem to mistakenly believe, by releasing your software GPL licensed, you do not give up any ownership or other rights. While you grant other people limited permission to your code, you still have rights including the right to license your code under other (potentially lucrative) licenses as well.

Licensing the software under other licenses does get more complicated once other peoples contributions find their way into your codebase, though. If you intend to license your GPL software under other licenses, you will want to control who can contribute to the codebase (See Part II, coming soon), and work out agreements with them.

3. BSD-like license

Using a BSD-like license on code makes it available for everybody to use, with very little restriction on what they can do with it or how (usually the main stipulation is how credit is attributed). It's really not too far from making the code public domain.

The upshot of a BSD-like license is that you (and everybody else) can do just about anything you want with the software. When other people contribute code, they're giving you that permission as well.

The downside of a BSD-like license is that someone else can take your software, and go make it (via big modification, or slight modification and promotion) into something huge-- and all you will be entitled to is a small credit. Now, the reality is that this could happen if the software was GPL licensed as well, but at least then you'd get access to the modified source code.

Conclusions

Ultimately whatever license you choose someone can always go and (rewriting if necessary) make something big out of your software, so (I keep telling myself to) worry more about the upsides and less about the down.

Proprietary licenses are really good for software where you feel you (or your close associates) will be working on the software a LOT, and want to maintain complete monopolistic ownership and control. This is very attractive to many people (myself included) for a lot of projects. It is completely respectable in my opinion, as long as you feel it is justified.

If however, you feel like a project would benefit greatly from having other people contribute, and the project has potential to be bigger than you've made it already, using the GPL can be a good choice.

I find BSD-like licenses to be good for licensing of libraries (or any other software that you generally want to be used as widely as possible), since people can link (and optionally compile) them with their projects, and not worry about the terms. Take zlib, which is used everywhere, or jnetlib, which isn't used as much but I'll mention for selfish reasons.


Coming soon: Part II (or: how to get other people to work on your open source project)

musica es muy divertida

Tuned the piano some more today, most everything had gone flat, no doubt due to the wood adapting to the new pressures of being in tune. Lather, rinse, repeat. Here's me and Biderman jamming with the piano and drums a couple of days ago. mmm. And here's me by myself today.

I'm starting to write a individual software developer's guide to software licensing and open sourcing, at least thoughts and tips from my experiences. I should be posting Part I (choosing a license) tomorrow, and Part II (how to make worthwhile open source software, i.e. how to get people to contribute etc) soon after. I know there may be other guides, but this will be my take (AND I AM RIGHT, DAMMIT! JK).

tunnel vision is now public, and open source

The topic pretty much said it.. Tunnel Vision, baby. GPL licensed, too. Not completely useless, just mostly.

OK so to make Christophe and others happy, here's LanMon, too. BSD licensed this time. Speaking of which, should probably make the other small utilities that are GPL'd BSD too. It's smaller to distribute... ha ha.

bleh

Feeling oh-so-assy.

Here's the halfway done Tunnel Vision app. Need to do the background image modes and an installer and I'll be pretty happy overall.

Got the piano fully tuned, though it's pretty off (I guess tuning strings flattens the others, when it was used to being so far out of tune), so I'll probably go tweak it again soon. Biderman and I managed to record some stuff with it, but I fucked up and haven't put it online yet. It sounds approximately halfway decent, which I'm happy about.

On friday I also cleaned a couple years of gunk from the fretboard of my guitar and bass. Yuck. I guess playing in a dirty garage has its downsides. Anyway...

Once I finish the tunnel vision app, going to make my Jesusonic/MT (multitrack)... a Jesusonic that's good for doing live performance, setting up loops etc. For making crap like this or this.

logo, music, etc

Saw Dungen last night, for their second SF show. Totally ruled. Wish I had a bootleg.

Also got the piano almost tuned. Tomorrow I'll spend another hour or so and it'll be in rough tune (then if I'm feeling it I'll go tweak it into even less bad tune). Yay. Sounds like a piano now.

I ended up using that last Cockos logo for the web site. Yay. I prefer it white on black, too.

And finally, decided to go ahead and finish the old TunView proof of concept I made over a year ago into a more complete application. Woot. Should be a day's work, and it's kinda useful (paranoia, mmm).

another logo attempt

Here is my fourth try at making that Cockos logo work. I like how it scales down for 32x32 icons too, kinda maze-like. Maybe I'll try doing a rainbow colored one, too.

Piano tuning toolkit arrived, I'll get my tune on shortly. woot.

rhodes, logo

Picked up a Rhodes Stage MK I off of craigslist, built in 1978, the same year I was born. Sounds sexy.

Experimented for a few minutes with making a Cockos logo, here are three versions of the same basic concept: revision 1, revision 2, revision 3. I think I like the last one best. Before you complain that it's too annoying looking, understand that it is supposed to be. There's a faint bit of humor in there somewhere...

Oh, and here's a very good NINJAM autosong (the first 5 minutes anyway). Random people rule!

Now L1quid is coming into town to commence his 21st birthday drinkin'. Get ready to get tired of drinkin! I am (ready (to get tired of drinkin))!

a song, more updates

OK so updated things more, went away from the ol' <pre> formatting, and more to normal html, but only in presentation, not so much in the actual writing of entries, anyway. Maybe it'll look right on my treo, now...

The real reason I wanted to update, however, is this acoustic song (featuring David Wiener), which was a couple of first takes (since there was no time to do more), and I totally dig. He's so talented (in my opinion anyway) that he can take some crap I recorded as a ditty and make it completely work as a song. Anyhoo.

page updates

Did some nice little updates to the comments system to better show URLs and auto-link them. Also made a recent comments page that shows you comments sorted by date. And fixed a bunch of stuff (displaying bugs, security holes, begone). Perhaps I should publish this modified version of hlscript as hlscript++, or something.

/me drools and waits for the piano tuning kit to arrive. and my blisters to heal.

piano workin

Spent a few hours carving/painting/attaching new black (sharp) keys for the piano today, woot. Also started tuning it. I ended up killing my fingers (blisters and whatnot) since I lacked proper tools, but it started to take shape. I didn't break any strings, even (though Biderman did, haha). So this evening I ordered a tuning kit, to aid in this venture. I know, I should just hire a professional, but A) I'm not sure if this piano is worth it and B) I'm going to wait until the piano is in a (more) climate controlled environment. Tuning wouldn't last long where it is now. But tuning it myself is proving to be very fun, and you get some really weird sounds at different times, when you have each of the strings for a note off the right amount, the harmonics are really fascinating. Anyhoo...

hit me, another update

woot, made this page look like the pictures pages etc. fun with php. that is all.

Oh yeah, I also posted the Mac versions of Winamp on my code page, since nobody else seems to distribute them. Not that anybody would really want to use it, but a few people might find it entertaining.

planes and pianos

Been flying my F-27 more, so much fun. Tried increasing the throw even more 
today, but it was too much, and the servo/radio combination didnt have enough
precision for me to fly as smooth as I'd like-- which is a shame, cause the
snap rolls were fun.

When Francis was in town we got a Slo-V (made by Parkzone as well), too. We
didn't get to fly it while Francis was here, but I managed to yesterday, and
while it is in fact very slow, it's also very underpowered. At 65F 80' above
sea level, it doesn't seem to have enough power to get out of ground effect!
I don't think I ever got it over 15' up (ground effect is usually 2x the 
wingspan, right?). It does travel nice and slow, though. Anyway...
I picked up a free piano off of craigslist last night (thanks for the help, 
everybody).. Going to start fixing it up a little. And then once it's
somewhere that is more temperate I will have it tuned/etc. Starting to make new
tops for the sharp (black) keys, using some spare basswood lying around. 
If anybody has any good resources for piano parts, let me know. 

A terrible little jam I made with the new piano is here.

busy day

Somehow I managed to get up at 7am today, drink some coffee, and do a bunch of
things.

A year ago I bought little foam R/C ready to fly parkflyer from parkzone, 
called the F-27. Today I finally got my shit together and went to fly it. 
And much to my relief, I still had it (it being R/C flying skills, heh). Was 
quite a bit of fun, and that plane is so light and has so much surface area
that it's really quite entertaining, you can get it moving and then burn off
so much speed nearly instantly. So after my first couple of flights (at a 
baseball field in Potrero), I cranked up the control throws and went to 
Golden Gate Park, in the wind, and flew it some more. Fun fun yum yum. When
parkzone's 3D flyer comes out, I'm so getting one.

We had a pretty good rehearsal/arranging session today, too.  A big difference 
from the nearly 4 hour drunken jam on sunday.  I have to say, I've found that 
after playing a lot in NINJAM, playing in person is so much easier. In many 
ways, NINJAM makes for good practice (like training at high altitude, etc).

crazy times

The stuff going on in New Orleans (and the rest of the gulf coast as well) is
just insane. All of the articles I read end up really fucking with my mind.

There's shoutcast streams up of police scanners in the area, so we had some
little NINJAMs to them. Which was a very strange experience, listening and 
adapting. Wishing I could do something to help. Here is one 22 minute segment.
Complete with Brennan ranting on shit.

Having said that, we all can do shit to help, at least somewhat.
If only we had some real leadership who could take control of this mess.

I hate how everybody is all like "let's not make this about politics now" but I
mean really, when is it ever a good time?

Sigh. An extra $200 billion would go a long way in the coming year, too bad we 
already blew it somewhere else.

Oh yeah, and Top Gear is on the discovery channel now. Such a great show.
Interesting, funny, well shot, and just plain awesome.  The guys who make it 
seem like they must have a fucking awesome time doing it.
