Odd Git Licensing Message on OSX

Wed, 18 Sep 2013 23:28:52 +0000

Today,IOS 7 dropped to the general public. As usually comes with the release, there was an Xcode update. I updated.

For some time, I’ve been using the git bundled in Xcode as it makes it simpler to get updates as they come with Xcode. Today, that yielded an amusing message.

I use git via an alias in my .bashrc

alias git='xcrun git'

A simple version check reveals all:

git –version

Oops… git is apparently subject to Apple’s licenses.

Killing “find” Errors

Mon, 09 Nov 2009 05:46:53 +0000

I’ve used the unix filesystem search utility find for many years. Though, like most things, until forced to learn its deeper secrets, I generally get by with only the most basic knowledge.

One of the cool things about find is that you can specify a search and then execute an action on the results, all in one command.

This example is probably my most common use of find:

find . -type d -name .svn -exec rm -fr {} \;

This means: find, in the current directory (.), a directory (-type d), named .svn (-name .svn), and for every result (-exec) remove that directory (rm -fr {}) . The “{}” represents the matched path string, and the “;” is required to end the “-exec” command.

Mac Mini DVI-HDMI on LCD HDTV

Sun, 14 Jun 2009 21:26:49 +0000

I recently purchased a Mac Mini to be my home media computer. I plan to blog more about that later. For now, the only tricky thing about using a Mini has been using my TV for a monitor.

There’s a lot of noise on the web (or Google at least) when trying to search for a solution to using a Mini’s DVI output on LCD TV’s. Typically they recommend using DisplayConfigX or SwitchResX to tweak your display modelines, timing, resolution, and just generally dive deeper than I like into display configuration. My solution was MUCH simpler.

Foxmarks: Bookmark Synchronization Heaven

Sat, 21 Feb 2009 22:19:25 +0000

Long have I searched for the magic bullet solution to my bookmark synchronization woes. I’ve wanted a simple plugin that would synchronize my bookmarks between multiple installations of Firefox and Safari, thus making it simple to access said bookmarks from any computer, or between the two commonly used browsers on my Mac. I’ve looked at many options, but always the solution only allows me to sync one browser or the other, leaving me looking for some secondary sync tool to get between Firefox and Safari on my Mac itself, not via network or a proper sync.

Building a Hackintosh Successful Attempt #1

Tue, 17 Feb 2009 05:32:39 +0000

Since getting a Mac Book Pro for work, I’ve become quite the fan of OS X. As a unix/software guy, I really enjoy having the power of a BSD/Unix system readily available, without having to install some hack like cygwin. (I’m not knocking cygwin, it’s a really nice Windows add-on, but I prefer not to run Windows, in general.) I also like the OS X user interface, and lately, that it runs the very cool boxee media center software. So, I wanted to build a boxee box. My options were AppleTV, Mac Mini, or Hackintosh. The Mac Mini was more money than I wanted to spend for an untested solution. The AppleTV would probably be a good solution, especially now that it’s getting more testing from the boxee community, but I wasn’t sure about it. Finally, I thought that a Hackintosh would be a cool project, give me not just boxee but a full OS X system, and I could buy the parts for $235 from newegg. That’s a cheap computer, and especially a cheap Mac.

I went with an Intel D945GCLF2 motherboard. It’s a mini-ITX board with built in dual Atom 330 processors, the kind of CPU’s used in the new and inexpensive NetBook computers. It’s a very low power solution, but with the dual processors most of the research I did suggested it should do 720p HD content. It has a S/PDIF header for digital audio out, but requires an extra cable and I have yet to test it. VGA out is less preferable than DVI, but again, this is cheap, and my Samsung 46″ LCD has VGA-input, so it certainly works. Also, it’s limited to a single 2GB DIMM, so max out that RAM early. 🙂

I bought the following from newegg:

D945GCLF2 motherboard – $80
Any old PATA (SATA should work, too) DVD Burner – $25
2GB Kingston 240-pin DDR2 667 SDRAM – $21
APEX MI-100 Black/Silver Mini-ITX Case w/ 250w PSU – $56
80GB Western Digital SATA Hard Drive – $37
Shipping/Handling + rush processing – $15

Total cost: $234

Full disclosure: I later bought a cheap USB bluetooth dongle ($25) and Apple’s Bluetooth keyboard and mouse (full retail, ouch) as that was the best wireless control solution, but any USB keyboard and mouse combo should work fine for normal usage.

Bonjour Avahi Addendum

Thu, 06 Nov 2008 16:23:53 +0000

A while back I wrote about advertising Linux services via Avahi/Bonjour. Since then I’ve made a few changes to my setup.

First, I nixed netatalk for direct AFP support. My primary reason for using it was to gain a more Mac-like network filesystem which would make Time Machine happier. Well, Time Machine uses a sparse bundle disk image on it’s target; after learning about that, using AFP seemed a bit unnecessary. Also, Samba CIFS/SMB seemed to perform better. I don’t have solid benchmarks for this, but simple file copies seemed to be consistenly faster with Samba. One of the biggest annoyances about netatalk was all the extra hidden files and folders it created. I run a hybrid network, I have more Mac machines, but also Windows, plus I browse file systems on the command line quite often; and those excess files pushed me over the edge.

Second, I nixed Time Machine. Just when I thought everything was working perfectly, it completely blew up and could no longer access its data store. Not good for a backup solution. I plan to write about my new home backup solution sometime, but it’s basically rsync with a few key points.

A Project Idea: iPhoto to WordPress [gallery] Export

Thu, 23 Oct 2008 05:52:02 +0000

I’ve been spending some time getting my son’s blog setup. In doing so, I discovered that as of WordPress 2.5, there is built-in [ gallery ] functionality. Though it isn’t full featured, it’s pretty nice, and perfectly integrated with WordPress, since, well, it IS WordPress.

Currently the process to put photos into a gallery is:

Choose photos in iPhoto
Export chosen files to disk
Create new WordPress post
Add media via WordPress uploader

This isn’t too bad, especially for a geek who’s used to lots of arcane workarounds to accomplish simple goals. But… for my wife or others who don’t want the hassle, this is basically annoying.

Beating the Cisco VPN Client Error 51 On Leopard

Tue, 22 Jul 2008 16:10:01 +0000

I had this error popup today on my Mac OS X Lepopard 10.5.4 machine.

This is not cool as, well, I NEED MY VPN TO WORK!

Thankfully google came to my rescue. The solution is to execute the following in Terminal:

sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart

Thanks for the answer, VirtuallyShocking.com.

Plainview: presentations ala web

Thu, 05 Jun 2008 09:18:11 +0000

I just stumbled onto the coolest little app for Mac. Plainview is a web browser based on WebKit (also the guts of the Safari browser). What’s unique is it’s intended to NOT have chrome (the name for all tose fancy navigation bars, address text boxes, menus etc). It’s slim… so slim the chrome is non-existent. This is a full-screen mode web browser, intended to utilize the full screen real estate for presentations! Essentially, instead of having to take screenshots of websites and put them into power point or something, you can just demo the site. It’s awesome… and i’m not even explaining it as well as they did… but I am tired. 🙂

Using Microsoft Entourage on my Mac

Wed, 26 Mar 2008 11:01:30 +0000

I’m not really a Microsoft fan, nor do I consider myself a Microsoft hater. I generally like Linux and free Open Source software, and as a network and software engineer type I really like the power and flexibility of Unix-like operating systems. I made the switch to Mac because I wanted to see what all the fuss was about, and if I would benefit from a “Unix like system that just works.” Though there were a few bumps in the road, I’m pretty happy overall. Sometime maybe I’ll post about my Mac experience and thoughts in a broader sense.

Advertising Linux Services via Avahi/Bonjour

Sun, 27 Jan 2008 22:20:42 +0000

Update: most of this information is still correct but an update for combining service definitions into one file and setting an icon is available here: bonjour-avahi-addendum

In my last post I outlined how I followed others’ directions to enable netatalk on Linux and Time Machine backups to a shared AFP folder. Originally, I also described how to put all your shares on netatalk. I suppose if only have Mac clients or you REALLY want to use AFP, you can do so. As I worked with files over AFP shares, I started noticing that the performance seemed to be quite bad. No, I didn’t benchmark, but copying large video files to a shared folder over my gigabit network was substantially slower over AFP (netatalk) than over CIFS/SMB (samba). I use my network shares pretty heavily, so this was a concern. Also, netatalk tries very hard to replicate an HFS filesystem complete with resource fork support. This means that your shared directories end up with lots of extra folders named “.AppleDouble”(and a few others) containing Mac specific info. (Note: even on CIFS you’ll get the “.AppleDB” folders unless you disable a setting in Finder. I can deal with .AppleDB better than .AppleDouble AND .AppleDB) So, because of these two issues I decided to try using CIFS and samba again.

Time Machine backup to Linux via Netatalk

Thu, 24 Jan 2008 07:26:49 +0000

So, when I got the upgrade from Tiger to Leopard on my MacBook Pro, I was looking for a good backup solution. I’ve used rsync in the past, but when I saw that Apple had a new Time Machine backup tool, I was curious to give it a shot. The catch is you basically needed an external USB or Firewire drive, until they recently came out with the Time Capsule. Anyway, tonight I got the itch to really see if I could make Time Machine work without buying extra hardware. I mean, seriously, I’ve got a good hunk of mirrored disk sitting on my home server; that seems like a good place to do backups.

Some googling found me this link to a blogger who’d done it!

I’ll make my own version of this post, since I had a few differences from the original I where I found the info.

Safari Session Save & Restore with ForgetMeNot

Fri, 09 Nov 2007 14:46:12 +0000

My foray into the Mac OS X world is fraught with daily challenges as I try to learn my way around this new environment.

Firefox has long been my browser of choice on Windows and Linux. So now, I’ve used it on Mac, and while I still like it, I’ve felt the urge to try out “Mac native” apps such as the bundled Safari web browser. For the most part, switching to Safari meant learning new keyboard shortcuts, but one thing that was really killing me is that if I closed Safari or it crashed, I lost all my tabs. I am a pretty heavy user of the auto session save in Firefox.

Tabbing to HTML Form Elements in Mac Web Browsers

Wed, 31 Oct 2007 20:33:18 +0000

So, I’m a MacOS newbie, just switched over from Windoze / Linux. I figured, it’s cool, things “just work”, and it’s got a Un*x/BSD core. What else is there? Hehe, the interface has definitely been a challenge.

So, the first huge problem that drove me nutz was that in Firefox, I couldn’t tab to checkboxes, some buttons, multi-select boxes, etc. I asked around, but found others with the same problem.
