Bestselling Laptops

Posted on by

Mark Pilgrim has a great picture of the top laptops on Amazon.com right now. What I found interesting is that the first Windows laptop is #6 (and no it’s not running an Intel), The #1 and #2 goes to Mac OS X and Linux.

  1. Apple Macbook 13″ (2.4GHz)
  2. Asus Eee 4G 7″ (900MHz)
  3. Asus Eee 4G Surf 7″ (800MHz)
  4. Apple Macbook 13″ (2.4GHz)
  5. Apple Macbook 13″ (2GHz)
  6. HP Pavilion DV2740SE 14.1″ (2Ghz AMD Turion 64 X 2)

Taking a look at the competition it’s pretty clear why. The Times They Are A-Changin’.

That new 9″ Asus Eee looks pretty nice. What would be ideal is if they made the 7″ with a higher resolution and kept the price the same. 9″ is a little large for this class of mobile computing.

rsnapshot For Mac OS X

Posted on by

Lately I’ve been using rsync to keep two hard drives in sync. I’ve been thinking of switching to rsnapshot since it would give me with incremental backup which is much better. What I’ve yet to figure out is if it can handle resource forks (with Apple’s special flag in rsync), and HTS+’s. Google hasn’t returned much on the combination, so apparently there’s very little experience out there. As a result I guess I’m sticking with the more simple rsync until I see otherwise.

Resource Forks Suck

Dear Apple,

Please kill off resource forks. They add an unnecessary complexity to data archiving and management that’s unneeded by todays standards. Since Mac OS X it seems only a few places exist where resource forks are actually used. For example the older pre-Mac OS X “font suitcases” used a resource fork, while the modern “Data Fork Suitcase Format” as it’s name implies, does not1.

One could argue keeping resource forks is good for legacy purposes. But since Mac OS X 10.5 can no longer run Classic even on PPC systems, is there really a need?

If that’s really not possible, could you please make rsync suck a little less?

Ideally since rsync 3.0 looks like it will be a lot better, make it a high profile download for Mac OS X 10.4 and 10.5 similar to what was done to push Safari 3.0. That would be a nice stop gap solution.

I hope you’ll fix this since it’s a real pain in the butt for people like me.

Thanks,
Robert

Mac OS X 10.5.2 Leopard Update

Posted on by

Apple released Mac OS X 10.5.2 weighing in at a hefty 343MB. Generally speaking, Mac OS X 10.5.3 is where the OS is really firing on all pistons. Before that, it’s similar to Windows before SP1. Still some rough spots. This release fixes a fair number of bugs, and adds some polish.

So far so good, it installed fine, rebooted and I’m up and running. Overall not to much changed for me, since my mini doesn’t support menu transparency (which you can now disable). The list view for stacks is a very welcome addition. I’m glad they decided to include that. For larger stacks it’s so much easier to browse.

I don’t have Time Machine running on my mini, so I’m really not sure why Apple decided to make the new menu item for it on by default. In my opinion it should be off unless you setup Time Machine. So I turned that off, and reclaimed a few pixels of valuable menu space.

Still not fixed is the Apple Mail issue I noted before where you can’t view nested mailboxes in IMAP. Maybe next time.

Apple Mail And Folder Management

I use Thunderbird on Windows, but from time to time like to fire up Apple Mail when on my Mac.

Why is it Apple Mail on Leopard doesn’t seem to allow me to view a few mailboxes nested under the inbox on an IMAP account? I haven’t tried under POP3, though I’d venture it’s the same limitation.

You would think they would at least show it linear if it couldn’t display it under inbox. Instead what it does is just not show it. Perhaps it’s important for me to be able to presort my inbox to make it manageable.

MacWorld SF 2008

Another year, another great day of news coverage. I’m obsessed with watching it evolve and monitor several sites throughout the keynote. As expected this was a pretty big one. I suspect this year will contain the most product announcements of any year for Apple. They have a lot of products due for a refresh and announcements expected. Even Steve himself said:

All of this in the first two weeks, and we’ve got fifty more weeks to go.

In all the keynotes I’ve followed, this was the most aggressive agenda. 2008 is going to rock for Apple products.

ZFS On Mac OS X

Posted on by

Anyone with an interest in file systems, data management, large scale storage, and security has been keeping an eye on Sun’s ZFS for a while now. Apple looks like it will ship the first consumer-targeted OS to feature workable ZFS support. It’s in Leopard, but read only. Apple has now released binaries and source. It’s still not ready for prime time (not even bootable, and has some serious bugs), but it’s progressing.

While not in Apple’s implementation yet (it is however planned), ZFS supports things like compression and encryption. ZFS is also a 128bit filesystem, so for the foreseeable future, it’s enough storage for anyone. Dynamic striping and Snapshots are also extremely interesting. I’m curious to know how snapshots in ZFS will integrate into Mac OS X 10.5 Leopard with Time Machine. I wonder if complete ZFS support will make a 10.5 revision or if it will be read-only until 10.6.

I am however curious if they have given any thought to solid state storage. It’s pretty clear that’s where the future is headed. While ZFS targets size rather than performance (meaning the two won’t collide for some time as solid state storage won’t be practical for large storage arrays for a few more years), I wonder if ZFS would be able to do things like wear-leveling. So far I haven’t seen any documentation to hint that the feature exists (I’d presume it doesn’t). No idea if it would be something that could be added or if it’s nearly impossible.

New Home Server

Over the past few weeks, I’ve been in the process of setting up a new home server. The previous one was an old Beige G3 (266MHz) running Mac OS X 10.2 that was starting to show it’s age. The new system is a much more capable B&W G3 (400MHz) running Mac OS X 10.4. Despite only a slight increase in clock speed, the B&W G3 has much more modern hardware (USB, Firewire) not to mention more room for more storage. The opportunities are endless.

Decided to go with a multi-drive setup considering the extra bays. The system had a still usable 40GB Seagate Barracuda IV drive which would make a perfect system disk for OS/Software. Installed via a ACard ATA/66 controller it’s no speed daemon, but for the purpose it’s fine. For the data drive I decided to get a SIIG SATA card and a pair of Seagate SATA drives I found a good deal on at BestBuy. The drives were Seagate ST303204N1A1AS, which corresponds to 320GB. Inside the boxes as expected were (the newer and better) ST3320620AS, which is a Seagate Barracuda 7200.10 with firmware 3.AAE (not the AAK people have had in the past). Perfect.

Next I wanted to replicate data across the drives on a cron. Initially I was thinking rsync, since as of 10.4, it’s resource-fork aware. It turns out that’s not really true. I ended up going back to SuperDuper to copy between the drives. It only copies changed files, and once a week will delete removed files (so if you accidentally delete something, there’s still a chance to recover, unless you do it at the wrong time). Not a bad solution IMHO. Still would prefer rsync more. Initial backup took less than 1/2 hour. Just a few minutes should be enough to keep the disks in sync. I briefly considered setting up RAID, but decided against it since RAID is not backup. It doesn’t protect against things like corruption.

Apple needs to kill off resource forks ASAP. They should have done so when moving to Mac OS X several years ago.

Next up, I tried putting a copy of TechTools Pro I no longer use on my Mac Mini since upgrading to Leopard on the system, but that resulted in some drive problems that I couldn’t resolve without uninstalling. They seem to know about the problem, but haven’t fixed it. You see the following error repeatedly in the system.log file until you reboot:

kernel[0]: IOATAController device blocking bus.

Drag.

Also updated mrtg, and this time compiled GD, libpng, libjpeg, etc. all by hand, rather than use fink. Last time I went with fink, which saved me a few keystrokes, but when fink no longer updated packages for 10.2, left me high and dry. This time I think I’ll avoid it when possible. I need to try getting RRDtool setup at some point, since it’s so much better.

I use a few php scripts for easy admin of the box, and decided PHP 4 wasn’t adequate since it’s pretty much discontinued. So I upgraded to php 5.2, and all seems good so far. I think Apache 1.3.33 will serve me just fine for the moment, so not upgrading that.

I might give setting up BIND a try, since local DNS would be pretty handy for easily accessing the server without modifying the host file on computers.

I also disabled things like spotlight, which have absolutely no purpose on this box.

On another note, glib for some reason won’t compile for me. No clue what’s going on. Overall it’s looking pretty good. Should be about ready for real use. Just want to make sure the backups work as expected.

Calculator Phoning Home? Not Really

Wasn’t sure what this is all about, but according to Little Snitch 2.0 (which is awesome by the way) the Calculator in Mac OS X 10.5 (Leopard) apparently phones home. Based on the url http://wu-calculator.apple.com one would assume that’s checking for updates (wu typically stands for web update). Though I find this somewhat odd considering Mac OS X has an update system that’s all encompassing. I decided to take a closer look. Earlier it was said that 10.5 was phoning home, though that turned out to not be the case.

Calculator Phoning Home

So I did a little sniffing around (literally packet sniffing), and here’s what I found. On load it sends the following (seemingly blank) request to apple for currency conversion info. The response is the exchange rate. I’ve got a copy for reference below for anyone who wants to see. Calculator seems to use CFNetwork to communicate (not surprising). What’s interesting is that this info doesn’t seem to be cached, every time you load calculator it’s requested.

So yes, it does technically ping the mothership, but no it doesn’t seem to send back any data worth being concerned about. The only thing noteworthy is the cookie. The cookie itself is characteristic of Omniture, an analytics company (who provides analytics services to Apple among many of the largest sites on the web). This seems like a side effect of the implementation (likely sharing stuff from webkit). I don’t think Omniture is pinged during this transaction, so unless Apple were recording that cookie and matching it against web analytics data. I’d consider that extremely unlike even if I put a tin foil hat on my head. I guess Apple could further neutralize any privacy concerns by modifying the implementation to not send a cookie. At that point they would only have your IP to go by (which could be behind a proxy and therefore isn’t very reliable). I don’t think think this is a privacy risk, but also don’t think it would be so bad for Apple to modify and drop the cookie to make it more anonymous. Or at least give the option to not request data every time.
