Unbootable Mac

Note to self: When your Macbook is having repeated issues waking from sleep, don’t sleep it in the middle of installing a big piece of software that has a complicated installer… On forcing a reboot the damned thing hung at the ‘Starting Mac OS X’ scroll bar screen, and stayed hung. Looking at the syslog at the console showed the last boot activity was coreservicesd crashing. Uh Oh, time for some panicked googling.

Solution: Boot into single user mode using Command-S, mount the root filesystem rw, then: mv /Library/Caches /foo followed by reboot. Everything seems fine now, just need to restart that installation ;-)

Server disk woes over and done with?

I finally managed to get all the relevant modules into an initrd this evening, and managed to upgrade from the SuSE 9.3 stock 2.6.11.4-21.13-bigsmp to the current rpm from SuSE 10.1, 2.6.16.21-0.13-bigsmp. The difference is immense. On excalibur, which is an IBM x335 with dual SCSI drives in a RAID1 mirror, I’ve gone from 2.4MB/sec to 69MB/sec.

A painless process, albeit made a little hairier by having to play ‘hunt-the-dependency’ with drivers in the initrd as LSI seem to have rejigged things since the old kernel.

If only I’d twigged it was a driver issue that was thwarting me sooner… at last I can type ‘ls’ without people whinging at me!

On the bright side, my VIA based dedicated server from BlackCat seems to be coping with the load of teamspeak plus 3 or 4 forums admirably.

Week 51 tablet firmware & video encoding.

Got around to installing the 3.2005.51-13 firmware today (available from Nokia) over lunchtime. Flashing went without a hitch, and setting everything back up wasn’t too much of a chore. Restored bookmarks from backups (the utility to back things up seems reliable so far…), but left settings to be set manually as I wanted to get rid of an undeletable mail account that I’d acquired. Everything seems snappier (as with the previous upgrade), and it seems that after importing excalibur’s SSL cert into the tablets store IMAP now works, sort of. No proper folders or decent multiple account support still and SMTP seems mysteriously broken, but it has been checking mail every 5 minutes all afternoon and hasn’t died yet! At this rate it’ll be usable by next year…

While reinstalling software I decided to try re-encoding an XVid for use with the video player again… last time I tried I didn’t get sound. Since then I’ve found Media Convertor, which works as expected, producing very watchable video.

WebDAV b0rkeness

My boss recently was having trouble mounting WebDAV shares on his iBook (running Tiger 10.4.3) - it had been working fine, but just stopped working for no apparent reason, giving a ‘-50′ popup error. Sniffing traffic on the network showed the machine wasn’t sending out any https requests… there were however some messages in the system logs (UNIX core to the rescue!), and to cut a long story short, a quick ‘Repair Permissions’ from disk utility fixed it. Still a bit uneasy about why this happened in the first place though.

N770 First Impressions & Firmware Download

Got a Nokia 770 on release weekend, thankfully as they seem to have sold out very quickly. First thing to do with it ? Install stuff of course (after playing with the great browser and suprisingly useless e-mail client). Of course, after I installed an xterm, ssh client and gaim the thing bricked itself. And no firmware to download on the official nokia site. Well, some searching came up with a developers firmware download link. Coupled with the OS X firmware flasher and the USB cable, the following command line fixed things, along with enabling root access via R&D mode: sudo ./flasher.macosx -F Nokia_770_0.2005.42-9.bin -f –enable-rd-mode -R

At least the very slick phone bluetooth setup and setting things up to work with the office and home wireless made the reinstall painless. Lucklily I didn’t experience the WPA key-length issues some people have reported. And I discovered the ‘backup all settings to MMC’ option, which will make life easier in future.

Once it was back up and running again, I battled the e-mail client some more. Seems it dislikes IMAPS (at least to my cyrus mailstore) and/or large mailboxes. POP3S and a pruned-to-7-days mailbox seems to placate it, but I’d really like to see proper IMAP support - Inboxes-per-account, folders etc shouldn’t be that hard to implement, surely?

Realplayer comes installed with it, and copes fine with the BBC radio streams. Not quite perfected settings for reencoding DivX videos for optimal playback yet.

The web-browser (Opera I believe) seems to cope fine with most things I’ve thrown at it - certainly it’s great for general forum whoring, the superb screen making for excellent text, even at small font sizes. On the ‘home’ screen there’s a neat RSS reader along with a slightly random ‘home’ page button (which I don’t think I’ve used yet), and a DI Play button… uh… internet radio I mean ;-)

Overall, worth £250, and a nice first product in what I’m assuming will be a series. A few rough edges, but that’s to be expected IMO. All I’d ask for in the next software release (due in 2006 allegedly) is a better e-mail client, and preferably some PIM functionality (iSync!). Be interesting to see what IM and VoIP standards it will support in this release.
