My latest hobby is deleting email. I used to keep it all, but I get way too much and I don't care about a lot of it. Now I've started to delete it. My new rule is if a machine wrote it, I am not interested in keeping it very long. It might be news, it might be a special offer, it could be a cvs commit, an error message on my server, but basically if I didn't look at it and act on it in a certain period of time then a) it's now old and probably useless and b) I can probably get the same information still somewhere else.
It's so liberating to see my inbox full of just personal emails that people typed to me. I think subscribing my own personal email to mailing lists is a time stealer, let alone Amazon, Barnes&Noble, Borders etc etc all spamming me regularly. So... they have all been nuked, even from my backups!
I've even discovered that Apple's Mail.app is not quite so slow as
I thought - it was doing quite a good job in face of a massive
overload of impersonal machine generated email.

Multiple Bifurcations is a term that I first heard from Andy Grove when he explained the future of Intel product positioning.
In my case, however, it's just a good term for how I'm slowly losing my mind. Instead of being interested in "Unix", now one has to consider Solaris, Mac OS, Linux, BSD etc. They all have their strengths and weaknesses, such that I can't just standardise on one. I love my old SPARC machines, for example, and Solaris is best on those. I use my various Macs for music, video, email and web browsing. Gotta have those. But for my webserver, my home-brew Slackware Linux machine is still plugging away after several years reliable duty.
Similarly, for blogging, I started off using Blosxom on Linux. It's really simple and I can work disconnected too. On my webserver I can post from a simple ssh session, or I can work on my mac and then upload afterwards.
However, for blogs with themes, photos, counters etc, I have been
experimenting with "iWeb". It's just about ok for a first 1.0 release
of a product, but has some shocking limitations. For example if you
have a slideshow, every photo is shown with a sort of reflective
foreground, like it was standing on a black shiny surface. There is no
way to turn this off. Personally I hate it. HATE IT. Also there is no
way to participate in the quality of photos, I can't ask for bigger
images, or smaller thumbnails, or more sharpening. I think that Flickr
is most likely better. Finally, a friend of mine has Aperture and a
quad Powermac with 4.5GB and produces some fairly nice slideshows
using that setup.

My Sun rep was kind enough to arrange an Ultra 40 box as a demonstrator. I've had it up and running for a couple of weeks now and overall, it's great. Herewith some of the highlights and lowlights. Drawbacks :
Otherwise though, it's an awesome machine. I replaced the cheap mouse with a Logitech item I had lying around, since the "middle button" function was sticky (you push in the scroll-wheel, but often it wouldn't click out again). Since the machine has convenient front-facing USB ports I simply plugged in the extra mouse and it just worked. I love USB.
I even like the new Sun Type 7 USB key, and fortunately it came with the PC layout that I prefer (Ctrl key below the shift key). If I were Rich Teer I would have been disappointed not to get the unix layout, but I've just never learned to type that way.
The noisy high-speed fan noise is only the first time power is applied to the box, once it settles it has, so far, never made that kind of noise again, apart from one time it accidentally got unplugged.
Since the machine is a demonstrator, I wasn't sure what kind of spec. I would be getting. I discussed it with my rep and tried to emphasize the things that are useful in my team and those that are not. In particular, we don't use a spectacular amount of RAM, nor high-end 3D visualisation.
For some reason, though, I ended up with the "large" configuration, which is as follows :
So I probably have the fastest PC at my office.
The machine came with Solaris 10 pre-configured, however since I no longer have any Solaris responsibilities at work, I reinstalled it with Windows XP Pro 64-Bit edition.
Sun did a nice job with the Windows drivers for this machine, after downloading and burning the ISO CD image they provide, we were able to get everything working nicely.
Once I finish setting the machine up for my main responsibility
(running a Windows development team) I hope to stick in a second hard
drive and set up a double or triple boot environment so we can explore
this machine under Solaris 10 and Linux as well. Our source code
repository is kept on Unix and runs a homebrew bunch of perl scripts,
so a nice unix dev box may come in handy from time to time also. I
have some ideas about using ZFS with our CVS setup, and this box would
most likely just fly as a ZFS host.

I've been away from blogging for a bit. I started blogging due to some encouragement from the OpenSolaris pilot crew and Jim Grisanzio, but then the OpenSolaris launch was so amazingly full of life and expert blogging, I didn't feel like there was much more to say. But life has settled down a little bit and perhaps I will be able to find the time.
So what's new? Well, lots of things... apologies for a 'portmanteau' blog post, I will behave myself and categorise entries properly following this one.
On the Solaris front I recently dipped my toe into Solaris x86. Previously over about 10 years of using Solaris, I had never seen or logged into an x86 incarnation. I converted an old Linux machine I had lying around unused and got b27a installed fairly easily. Netbooting, loopback filesystems and endian-neutral DVD images should make this all extremely convenient for the well-organised, however for hardware where it's unknown whether the OS will install, I prefer good old fashioned CD images. After all if there is a good chance that the install may fail at any point, then it makes sense to sit and babysit the process... so then feeding in CDs every few images is not much additional hassle. That's my excuse anyway.
The nominal reason for all this was I wanted to play with ZFS and the machine seemed like a nice target since it has 4 scsi drives. I got as far as making a mirrored pool and filesystem and mounting it and creating a txt file. It really is as simple as the blogs from the ZFS team claim. Very impressive. I plan to use the mirrored space for my most critical files - my documents, email, programming projects and digital photos. I've been distracted from getting any further by problems with the X11 configuration (naturally, I always have problems with this it seems) and also the NIC configuration.
The machine has a genuine DEC Tulip chipset 10/100 ethernet card, which unfortunately cannot be persuaded to run at anything better than 10Mb half-duplex under Solaris. Fairly horrible for a machine I am prepping to be a fileserver. I tried various setting in /kernel/drv/dnet.conf including a reconfiguration boot each time, but to no avail.
First impressions are that Solaris x86 on this machine, in its default install, is a bit of a dog. Slow to start, slow to shut down and not that snappy in between. However, I am sure this is partly because lazily installing the entire set of software on a machine with only 256MB RAM, as I did, makes no sense. It was a first install, I plan to do it again when a ZFS enabled build makes it to an official Solaris 10 point release, or perhaps Solaris 11 comes out. And ... yes, I did know that I could pick and choose the packages myself if I wanted to. For a first install the urge is always to finish the job and she what the machine can do.
On the other hand, Solaris nicely recognized both SCSI host adapters and didn't barf when it noticed the IDE channel is idle. Yes, this is a PC with nothing connected to the IDE controller : SCSI hard disks, SCSI cd-burner, SCSI tape drive, SCSI zip drive. Has an original Athlon 750Mhz slot-A cpu. In 2001 this was something of a dream machine in my eyes.
For my trusty Sun Blade 1000 I upgraded the backup facilities. As much as my DDS3 drive gave good service, a Quantum DLT7000 is a significant step up. I managed to get a factory refurb with very low hours on the heads for about $300 on Ebay. 35GB native capacity and DLT tapes have a bit more reassuring heft and solidity than DAT tapes. Some people apparently feel that the non-helical-scan formats are a more reliable choice for backups, I wouldn't know, but choice is always useful. I can for example backup up selections from that machine to cheap, ubiquitous DDS3 media, but occasionally do an archival level 0 dump to good old DLT tape and put it away for safekeeping.
Other stuff I'll blog :
