Still, the fact remains:

I Did Not Know about multitail.

I’m watching eight different log files from a Windows server through CIFS on my Windows 7 desktop where I’m running Cygwin and multitail. This is both pleasant and awesome-looking, which is not normally the case for watching eight different log files, especially on Windows.

No Solaris 11 for Legacy UltraSPARC http://www.semanticnoise.com/2011/06/no-solaris-11-for-legacy-ultrasparc/ http://www.semanticnoise.com/2011/06/no-solaris-11-for-legacy-ultrasparc/#comments Fri, 17 Jun 2011 19:03:39 +0000 jmcmurry http://www.semanticnoise.com/?p=387 Continue reading ]]> I don’t do a lot of Solaris anymore, and though I’m interested in several of the new features in the upcoming Solaris 11, I wasn’t aware until today that it wouldn’t run on most legacy UltraSPARC systems:

Support for legacy systems that have included the UltraSPARC I, II, IIe, III, IIIi, III+, IV and IV+ processor architectures (as reported by the Solaris ‘psrinfo -pv’ command) has been removed. All Oracle SPARC Enterprise M-Series Servers and Oracle SPARC T-Series Servers will continue to be supported.

Source: http://www.oracle.com/technetwork/systems/end-of-notices/eonsolaris11-392732.html

I’ve always liked the T-Series systems, and have personally achieved what I consider impressive workload consolidation using a few of them. It’s not entirely clear what Oracle means with the above statement, but rumor is that support for the sun4u architecture is gone. That’s a big change from the Solaris 11 Express HCL. I imagine there are lots of places where this means “we will never ever run Solaris 11.”

Reminds me of a certain fruit company. Time marches on.

My Favorite Small Mac OS X 10.7 Features http://www.semanticnoise.com/2011/06/my-favorite-small-mac-os-x-10-7-features/ http://www.semanticnoise.com/2011/06/my-favorite-small-mac-os-x-10-7-features/#comments Mon, 06 Jun 2011 21:40:31 +0000 jmcmurry http://www.semanticnoise.com/?p=370 Continue reading ]]> As usual, some of the most interesting (to me) new features in the next release of Mac OS X are in the cheap seats, not on the highlight reel.  The following items are excerpted from http://www.apple.com/macosx/whats-new/features.html after today’s WWDC announcement of Mac OS X 10.7 Lion:


[Address Book] Yearless birthdays

You can now add birthdays to your contacts without including a year.

[FileVault 2] External drive support

FileVault 2 supports encryption of external USB and FireWire drives.

[Finder] Merge folders

When you try to combine two folders with the same name, the Finder now offers to merge them into a single folder.

[Internet Restore and Utilities] Built into Lion

OS X Lion includes a built-in restore partition, allowing you to repair or reinstall OS X without the need for discs.

[Networking] Low-power wake

In OS X Lion, your Mac can wake up for services such as file sharing, backup, and more without the need to turn on the monitor or attached USB devices.

[Networking] NFSv4 support

Lion includes support for NFSv4. // Not that I’ll use it, but anything that helps NFSv4 is a good thing in my book.

[QuickTime Player] Rotate clips

If you open a video and it’s upside down or sideways, just rotate it to make it right.

[Safari] Drag-and-drop downloads

You can drag downloaded files from the Downloads list to your desktop for easy organization.

[Screen Sharing] Per-user screen sharing

You can remotely log in to a Mac with any user account on that computer and control it, without interrupting someone else who might be using the computer under a different login. // This is going to be a Really Big One for some people.

[System] Windows migration

With OS X Lion, you can migrate all the information from your old PC to your new Mac. Lion automatically transfers your documents, contacts, calendars, email accounts (Outlook and Windows Live Mail), and photos stored in Picasa, and puts them in the appropriate applications. // Family IT guys, REJOICE!

[System Preferences] Custom desktop color

Now you can create a custom solid color from the color picker. // Solves a longstanding embarrassment, which is always good news.

[Time Machine] Local snapshots

OS X Lion lets you take the Time Machine experience with you when you’re away from your Time Capsule or backup drive. Time Machine keeps a spare copy of the files you create, modify, or delete right on your Mac. Now if you accidentally delete a file while on the road, you can recover it from a local copy.

[Time Machine] Encrypted backups

Keep your Time Machine backups secure by backing up to an external USB or FireWire drive encrypted with FileVault 2. // This is a Really Big One in general.

[Other Features] Resize from any edge

You can now resize a window from any side or corner. // Solves another (and more annoying) longstanding embarrassment.


I’m looking forward to the big stuff like Versions and Mission Control (not to mention the kinda-amazing Lion Server deal), but these little things are always my favorite part of a new Mac OS X release.

Maggie http://www.semanticnoise.com/2011/04/maggie/ http://www.semanticnoise.com/2011/04/maggie/#comments Mon, 18 Apr 2011 02:20:35 +0000 jmcmurry http://www.semanticnoise.com/?p=328 Continue reading ]]> This is going to be sad.

Maggie is gone.

She had been sick for the last several months with nearly every horrible thing that can happen to a Boxer dog, and finally it just became too much. We took her to the emergency vet on Sunday and she didn’t come home. She’s better off, the pain is gone, she has found peace, and so on. All the standard things people always say absolutely apply here, and as usual, none of them help very much.

Maggie knew how to press the top of her head right into my chest when I needed it. Maggie smelled like maple syrup. Maggie loved having her belly rubbed, and cheese, and her big pillow on the couch. Maggie hated thunderstorms and wanted to hide under my office desk until they were over. Maggie limped out on arthritic hips and a bum leg to hop around in the yard under the giant oak tree with me because no matter how old she got or how much it hurt, she was still a puppy on the inside and she wanted to play.

Maggie was the first dog to notice Simon in his crib as we brought him home, and I will never forget the amazing look on her face when she saw him.

For eleven years, this beautiful, soulful dog loved me and I loved her. I have a 77 pound hole in my chest, and it hurts. I hope it always does a little bit; in that way, she’s still here.

New Job: St. Jude http://www.semanticnoise.com/2011/02/new-job-st-jude/ http://www.semanticnoise.com/2011/02/new-job-st-jude/#comments Sat, 19 Feb 2011 18:08:14 +0000 jmcmurry http://www.semanticnoise.com/?p=308 Continue reading ]]> I have a personal re-org announcement for you:

Yesterday was my last official day as a system administrator at The University of Memphis. I’m starting at the end of this month as a Enterprise Network Storage Architect at St. Jude Children’s Research Hospital.

I was at the U of M for a little over five years, and for the most part, I really enjoyed it. I worked with some good people in the IT Division and throughout the University. I did interesting technical work and had my share of successes. I developed professional and personal relationships that I truly appreciate. I started and finished a graduate degree in my spare time.

Most importantly, I met Molly.

I’m looking forward to St. Jude. It’ll be fun to work on projects where you can say “petabyte” with a straight face. I’m excited to contribute to the work the researchers are doing, and a quick walk through the halls of the main buildings makes it obvious that this work is important and often miraculous.

Most importantly, I can occasionally have lunch with Molly. And Simon.

– Yes, this is a mouthful.

Simon James McMurry was born Tuesday, December 22, 2010 at 8:11am. Eight pounds, three ounces, 20 inches.  Lots of hair, dark eyes, chubby cheeks, ten fingers, ten toes.

Simon gives a meaningful stare from his hospital bassinet (2010 Dec 22)

Simon is beautiful and funny and I love him more than I ever dreamed I could.

Since he’s been home, the three of us have gotten to know each other in a hundred different ways. Molly and I are doing great with him so far, but I think that’s mostly because he’s a really great baby. “Team Simon,” we remind each other when adult fussiness is about to flare up.

Simon sees the toy giraffes in his Pack 'n Play (2011 Jan 02)

I am Simon’s full time PR agent. Facebook, Flickr, Twitter, email, etc. There are lots of family and friends to keep in the loop. It’s been fun, but there’s a limit. I’m not interested in sharing minute details of his life to the public at large, but I suspect he’ll show up here quite a bit.

The New Apple TV http://www.semanticnoise.com/2010/10/the-new-apple-tv/ http://www.semanticnoise.com/2010/10/the-new-apple-tv/#comments Mon, 04 Oct 2010 19:42:44 +0000 jmcmurry http://www.semanticnoise.com/?p=284 Continue reading ]]> We have a new Apple TV. Herein, my experience.

It’s almost ridiculously small. Considering it’s basically a TV-connected 8GB iPod Touch, that’s not a surprise, but next to a Playstation 3 and 52″ TV, it’s nearly invisible. I really appreciate the lack of a power brick. It has a 6W power supply, which is maybe 1/16 what the PS3 requires.

Note that the Apple TV is connected via Ethernet to an Airport Extreme, which is connected via Ethernet to a cable modem on Comcast. Also connected via Ethernet to that Airport Extreme: the aforementioned PS3 and a Mac mini, which would ideally be on its way out of the den and into my office, but apparently not just yet.

Also note: no cable or satellite TV at our house, just Comcast data. We had Comcast WHATEVER_PACKAGE_SUPERB for the initial six months after the cable modem showed up, but never watched anything other than things we could already stream online. I have no interest in paying for traditional television service because it’s packed to the very top with Idiocracy-style nonsense.

But good TV, we like. We watch it (completely legally) via The Intarnet.

Apple ID

You use your Apple ID to turn on Home Sharing so the Apple TV can access content on iTunes from a computer on your network. I was immediately frustrated because my Apple ID had a space in the username, but the on-screen keyboard for the Apple TV doesn’t include a space character. I tried a few things, got frustrated, and used the Apple ID site to give in and change my Apple ID to an email address. This made me a bit sad; my Apple ID has been around for a long time and I had to go change it on all my devices. Once changed, the Apple TV set up fine and I could see iTunes stuff from the Mac mini. Bittersweet.

iTunes Content

I have a Season Pass on the iTunes Store for Mad Men. It downloads on the Mac mini. It shows up nicely on the Apple TV. It also manages to mark viewed content as viewed, which is very nice. I ranted for around five minutes the other day while walking to lunch about how annoying it is to play content stored in iTunes on Computer A (master) using iTunes sharing from Computer B. In my experience, metadata like played/unplayed, play counts, ratings, etc. doesn’t get updated on Computer A, which makes it much less useful. I know why this is, but it bugs me, especially for podcasts. The Apple TV appears to do this, at least for purchased TV.

I haven’t rented anything directly on the Apple TV. I don’t know if I’ll do that anytime soon, since most of the movies I want to watch are on Netflix and most of the shows are on Hulu. Most of both are Not Available for rental from the iTunes Store.

Songs, podcasts, my own non-iTunes Store videos stored in iTunes, etc. all played back fine on the Apple TV. Unless I find otherwise, my assumption is that if iTunes can play it, it can show up on the Apple TV. Works for me.

Netflix

The new Apple TV is much better as a Netflix player than the PS3 because there’s no fan, no disc (though that goes away this month, I hear), and both startup times and responsiveness are much better. It’s just a few seconds from selecting “Netflix” to hearing “Previously on Veronica Mars…”

One thing I don’t like: a few times while streaming Netflix video, it’s suffered from a cycle like this:

  1. Playback freezes for maybe ten seconds
  2. Playback resumes for five or ten seconds
  3. Repeat

This has only happened during a weekend night, but I don’t know if that’s significant. The last time it happened, I immediately switched to the Mac mini running Safari, netflix.com, and the Silverlight-based player, and saw no further hiccups. That makes me think there’s something different about the Apple TV (either its software or the Netflix backend it requires) that caused the issue. Annoying.

Hulu

Ha! It doesn’t do Hulu. The Mac mini seems like it might have to stay put. Hulu Plus is not the answer for me, and I don’t know what answer it provides to anyone who doesn’t want to watch back episodes of The X-Files on their iPad. (Not that there’s anything wrong with that.)

Hulu itself is great for watching recent shows, but Hulu Plus requires a subscription payment to still show you ads and not allow you to watch content you’re used to seeing on a mobile or TV-connected device. (Unless you have a Mac mini on your TV…)

It is deeply stupid to have to think about what device and signal path I have to use to watch an episode of freaking Glee.

I am well aware that the Apple TV will probably never let me view Hulu content without jailbreaking. I have made my peace with this.

Internet Radio

I listen to Groove Salad. It is great. It is a simple menu item on my TV now. This is awesome.

Flickr

It’s very easy to flip through pictures and slide shows from Flickr contacts. Images look nice and the UI is very responsive.

Except for those two times it crashed and the Apple TV had to reboot.

YouTube

I watched video from my friend Steven Bryant. I generally dislike actually using YouTube, but this looked good, was more or less easy to navigate, and provided a much more elegant experience than the YouTube web site or iOS app.

Except for that one time it crashed and the Apple TV had to reboot.

The Remote App

The updated Apple Remote app is on my iPhone. The gestures to control the Apple TV are not entirely intuitive, but the basics are fine. The big win is being able to use your iPhone to type on-screen, because using the IR remote is just as horrid as any other similar input method.

Incidentals

  • I haven’t noticed a method to control volume. This is good. Controlling volume in one place (the AV receiver) is much more intuitive and results in less frustration compared to the three places (app, OS, receiver) that I get with the Mac mini.
  • 100Base-T is all you get with the Apple TV. It’s meaningless, but I don’t know if Apple sells anything else without Gigabit Ethernet.
  • You have to use a dedicated menu item in iTunes (Advanced -> Choose Photos To Share…) to select images you’d like to view on the Apple TV. It seems weird, but since you never plug the Apple TV in (unless it’s broken), I guess the normal interface of select device, then select options wouldn’t work.
  • I mean it: it’s comically small.

I don’t regret the purchase, especially at $99. I’d like a few rough edges smoothed out, and I don’t know what to do about Hulu. I know there are other teeny-tiny media-to-TV devices on the market these days, but this is the one I have and it’s been good overall.

Windows Wireless http://www.semanticnoise.com/2010/10/windows-wireless/ http://www.semanticnoise.com/2010/10/windows-wireless/#comments Fri, 01 Oct 2010 13:39:38 +0000 jmcmurry http://www.semanticnoise.com/?p=271 Continue reading ]]> Dorks: I am about to trash Windows.

Non-dorks: Sorry, nothing to see here.

I think I first used wireless networking on a ThinkPad X31 back in like 2002 or something. The last time I regularly used a Windows notebook was maybe in 2004. Last night, I had the pleasure of helping set up a wireless network at my favorite Halloween scary place on some admittedly not-modern Windows hardware.

My observation: Using a Windows machine to connect to and use a wireless network remains an embarrassment.  The OS might manage it, or your manufacturer may have decided to put their own wireless management software in the way, but getting things to Just Work is fraught with peril.  Much more so if you’re smart and turned off SSID broadcast and enabled the best encryption your access point can manage.

The alternative is this:

Screenshot of Mac OS X 10.6 dialog for joining a wireless network

I sometimes use Windows 7 on a desktop and don’t hate it. I’m sure wireless configuration is better in Windows 7 (not that it could be worse), but I think I’ll stick with the alternative.

So here’s WordPress 3.0.1, which didn’t break anything, and seems pretty nice, and comes with a default theme that I think is better than other (free) themes I’ve tried in the past.

I really appreciate not having to maintain my own PHP. WordPress is good.
