It's been a mixed bag of a week, but at least I'm feeling well enough to feel like I've had a week.

Things I've learned this week:

  • Mac OS X does not have a 'csplit' command (say what?!)
  • Fink does have a package that includes 'csplit' ... so I also learned about Fink (took a big detour in the middle of a wee project for [livejournal.com profile] anniemal to install Fink on her machine; I am so very glad I wasn't doing that over dialup).
  • Lynx, the web browser, is my friend -- no, wait, I can't count that because I knew that already.
  • Screen-scraping is not as fugly as I'd feared (but it's still technically-ooky enough that I'd rather use other tools when I can -- I did look very carefully for buttons labelled "XML", "RSS", or "Atom" before resorting to my first screen-scraping script).
  • I have no USB keyboards in my house (okay, that's more "noticed because it suddenly became relevant", rather than "learned", but I felt like sticking it in the list).
  • I may have to start using Microsoft Outlook after all ... not to send or read mail, nor to manage my calendar, to-do list, and contacts, but simply as a data way-station because it's the one tool/format that all the different gizmos that I'd like to keep synchronized to each other (which I will use for info-management and communication) all know how to connect to. Sheesh.
  • The Ericsson hands-free adapter from two-phones-ago won't work on my current phone after all, even if I do remember where I left it.
  • I still generate more comments than code when I'm programming, at least when I'm going to let anyone else get a peek at it or might ever want to edit it in the future. I guess one good habit I deliberately acquired actually stuck.
  • "Model number" on the bottom of a Sun peripheral refers to the type of case the peripheral is housed in, not the interesting thing inside (fortunately there's also "Part number", which I really hope does translate to something like "this is such-and-such type of CD drive").
Things I have not yet learned:
  • How to make the camera-phone communicate to my computers -- it doesn't want to talk to the Windows software I downloaded (maybe that computer has a broken COM port?), and (at least as far as I can tell using Google and the "search" box on the Ericsson web site) there doesn't seem to be Linux software for it ... nor Mac, but I don't have access to an OS X machine that has an RS-232 port anyhow, so Mac software would have to be for OS 9 or earlier to be relevant anyhow.
  • How to make an iPod talk to a Linux machine (Google found me instructions but the phone stuff has distracted me from going through them).

It was nice to feel like a useful geek this week, a nice change from my usual "the world doesn't want a geek who can't work full-time" feeling. Okay, one project was a favour and the other was barter, so I'm not "working", but feeling like my admittedly rusty skills are useful is nice.

(Hmm. I wonder whether there's a version of iTunes for OS 9 -- that might be easier than setting up the iPod under Linux, once I get ahold of a USB keyboard.)


The weather seems to have finally made up its mind to be autumnal, after flip-flopping on the issue for a while. Wednesday night my house was too warm; last night and today it's been cool enough for me to want clothing (at least a bathrobe). Which reminds me that it's time to start putting plastic over the windows again, and past time to have been thinking about obtaining heating oil (I'm still probably weeks away from turning on the furnace, but I should've been sorting this out already).

Before Pennsic, I thought, "There ought to be a dip in fuel costs between the end of the summer travel season and the start of the winter heating season, right? I'll see what's feasible to obtain then." But after Pennsic, prices didn't exactly get friendly, and then Katrina gave oil companies an excuse to squeeze a little more. Whooooops! I blew that one. The one hopeful sign is that prices this week are about thirty cents lower than what I was seeing shortly after Katrina. Still, a couple hundred galloms of heating oil ... %wince%. (It looks like this house needs about 700 gallons a winter to stay a little chilly but not cold enough for guests to have to keep their coats on; half that if I just aim for not letting the pipes freeze and only turn it up when I'm ill or have guests; two hundred gallons if I keep it chilly and we have a really mild winter. But all of these estimates require that I repair/replace the electric space heaters that have died over the past couple of years, so that I can keep a bedroom, the office, and most importantly the bathroom at something warmer than "fingers feel like they're falling off" temperatures.

My brother has suggested biodiesel for my furnace. I haven't checked yet to see whether anyone's selling that locally, and whether it's much cheaper (and I want to double-check that it won't require modifications to my furnace, but I think that's true). Of course, he was talking about do-it-yourself biodiesel, meaning that I should go ask the local fast food restaurants to give me their used fryer oil and do whatever chemistry is needed to clean it up for use as fuel. I haven't looked up the steps, but I'm not feeling very hopeful about the job of processing a couple hundred gallons (the size of my tank) turning out to be something I'm up to unless I have a Really Good Week all in a row, fibromyalgia-wise. But I need to look that up.

Transportation of the used cooking oil would also be an issue to sort out, and I haven't checked to see whether restaurants are still throwing old oil away or have started selling it to commercial biodiesel producers already. Whee, another research project. If it does turn out to be both practical and nearly free, that could make my house more comfortable than it's been any previous winter.

But that's for next week. Today, I get ready for tomorrow.

Mac OS X does not have a 'csplit' command (say what?!)

What version of Mac OS X? 10.4.2 most certainly does.

[loiosh:~] ckd% which csplit
/usr/bin/csplit
[loiosh:~] ckd% uname -a
Darwin loiosh.broad.mit.edu 8.2.0 Darwin Kernel Version 8.2.0: Fri Jun 24 17:46:54 PDT 2005; root:xnu-792.2.4.obj~3/RELEASE_PPC Power Macintosh powerpc

There is an iTunes for Mac OS 9, but I think the latest is v2 or v3 and it may not support newer iPods.

10.3.9

Glad to hear they remedied that oversight in 10.4

I'm pretty sure the hand-me-down iPod I was recently given is an "older" unit. The itty-bitty writing on the back says model A1040, apparently from 2003. 40GB.

What freaks me out a little is that this handheld device meant for casual walkabout use has as much storage capacity as the file server for my home LAN.

My (employer-provided) camera phone does not transfer the pictures on the serial cable by any means so far discovered, even by reading the manuals and the support pages on the web.

It will quite happily transfer the pictures on the IR port.

... of all the annoying design decisions ...

Designers make some downright baffling decisions. :-(

I can probably find one that fits.

The phone should transfer pictures via the cable using the software on the Sony Ericsson site. Did you download the version for the Z500a? The serial port should be easy to test. Jumper pins 2 and 3 together, fire up a terminal emulator, and see if it echos back what you type.

I suspect you could burn straight veggie oil in the furnace, but you might look into the cost of cleaning the injector gun before trying!

I am using the software from the Ericsson site for the Z500a, yes. Or at least I think I am. At one point when I was looking at Z500a stuff, clicking on what I thought was a within this context" link got me to a page of downloads for a later model, but I'm pretty sure I got that sorted out before downloading the program. I'll try a loopback on the port later, or I'll try a different Windows box (once I stuff the RAM back into the one that's currently apart). A bad port would not surprise me. If it were expected to be this complicated, I figure you would have warned me, so I suspect a hardware or Windows-configuration problem.

I'd heard something about having to remove water and glycerine (or glycerides?) from used cooking oil ... but I haven't done the research yet. I'll see what Wikipedia says about it tonight.

There's always the possibility of a bad phone and/or data cable too.

I've seen two approaches to running diesel cars on veggie oil. It seems like the furnace would be similar.

1) Make biodiesel:

- filter out the chunks
- adjust the ph of the oil
- add methanol
- stir
- wait
- skim off glycerin (about 20% by volume)
- Everything that's left is biodiesel


or

2) the easy way (sort of)
-filter out the chunks
-warm the oil
-burn it

The problem with #2 is that the car won't start if the injection system is plugged up with solidified oil, so it must be switched back to diesel before shutting off. I suspect that a furnace would be ok if the tank doesn't get too cold.

An iPod is basically a Firewire (or USB in the case of newer units) hard drive. Only the latest versions of the iPod are USB-only; 3rd and 4th generation units support both, and the oldest ones are Firewire-only. If you've got the Windows version, it's formatted with the FAT32 file system, if you have the Mac version, it's formatted to HFS+. So you'll need hardware the supports either Firewire or USB, and a Linux kernel that both supports your chosen interface and has read/write support for the appropriate filesystem. FAT32 is no problem; HFS+ requires something relatively recent.

The music player portion of the iPod is all in a directory called iPod_Control (in the Mac version; I assume it is similar in the Windows edition but don't have a way of checking). Inside here is a binary file iPodPrefs, and directories Device, Music, and iTunes. Device contains two files, a binary file Preferneces that presumably contains your iPod settings, and a SysInfo file that contains hardware data in ASCII text. Music contains a series of sub-folders named F??, each of which contain the actual music (.mp3, .aac, .mp4, .m4p, etc.), presumably based on some sort of hash algorithm. Finally, the iTunes directory contains a set of binary files that contain the iTunes playlists and databases, and mapping data that connects these playlists to the music files in Music/F??/.

You can extract all of the music from an iPod by mounting it and copying Music/*/* to some other location. Loading music in is harder, since the files in iTunes/ need to be updated. You will need an application that understands the iTunes playlist and database file formats, since these can't be readily hand-edited. There is at least one GUI application for doing so - see gtkpod.sourceforge.net for more information.

There *is* a version of iTunes for Mac OS 9, but as I recall the last OS 9 edition was iTunes 2.x; I think this version supports iPods, but probably doesn't support the iTunes Music Store (and therefore can't transfer songs from the Music Store to an iPod because of the DRM issues involved). I don't know where you could download a copy - perhaps VersionTracker could help, but I doubt it's available from Apple's site.

I have a spare USB RS-232 adaptor. Works with OS X. Does have some sort of
speed limit (which is why it got replaced). It'll go 9600bps, but not 56K.
