Paint the Tiger, Carve the Swan

According to an item that just popped into my feed, there is now a version of Navicat that connects to Oracle DBs.

Cool. I like Navicat.

How do you pronounce XIB?

I’d say it as ZIB. You know, like xylophone?

You can’t have a class with the name “Availability” in a project built with XCode 3.1.

You can with XCode 3.0, but CFNetwork, and I assume a heap of other classes use a class called “Availability” to define if objects are available in a particular version of the OS.

I’m trying to make a control that allows me to indicate when a record in my application is synced with the AddressBook person of the same name - I have made it so that I can only enable syncing when a person with the exact same name exists in both places, but to indicate it, I want to use a button that shows a pressed-in state, but also alters the image.

I want the image to be black-and-white by default, but when pressed in, it becomes coloured.

Apparently, this isn’t possible. You can either have a button which changes it’s image, or displays a pressed in look.

Might have to subclass it.

Update: You can subclass it, but there’s no need to. Just give yourself a reference to it (myButton, for instance), and then:

[[myButton cell] setShowsStateBy:NSPushInCell | NSCellLightsByContents | NSCellLightsByBackground];

I’m about to create a small application that uses Sparkle to do updates - not to publish anything, but just to see how it works, and make sure I can. I read a couple of things before beginning. One was an argument against Sparkle, or rather, an argument for an Independent Software Update…

ISU would allow all applications to be upgraded at once

[From Stoneship > Thoughts on Sparkle]

Now, I have quite a few applications on my machine that I don’t use very often. Even something like Acorn, which I use maybe once a week, right down to stacks of apps I almost never use.

Some of these get updated quite often. I don’t really care to download every update on a regularly updated application, when I’m probably going to have multiple updates before I use the application again. So, I quite like that it checks for updates about as often as I use it.

Which means applications like Changes.app, which I use virtually every day, and ExpanDrive, which I use virtually every hour, are kept up to date, whilst Acorn, which I just used a couple of minutes ago for the first time for ages, are only updated infrequently.

This can be taken with a grain of salt - I don’t know much about Sparkle other than it is pretty cool.

Or how to make a single-display Mac Mini Media Center even better.

I have a Mac Mini that records all of my favourite programs (almost) automatically. It runs EyeTV (by default), and can play movies stored on either a local FireWire hard drive, or a LAN server (running OpenSolaris, and using ZFS, incidentally).

One annoying thing is that to set up a new smart playlist, or edit a movie, or do anything on the machine, whilst I can remote in and do stuff, this all displays on the TV.

However, using ScreenRecycler, it seems like I can trick the Mac Mini into thinking he (his name is jens!) has two monitors. Thus, with some swizzling, I can have the EyeTV full-screen display on the “real” monitor, and the desktop on the other one.

Doing this means that I can happily edit a movie (say, to remove advertisements), whilst the TV still displays the live TV (or being viewed video).

Run ScreenRecycler on the Media machine. You may need to restart if this is the first time you have run it, as it installs some driver. I’m hoping it’s pretty safe…

After running ScreenRecycler when the system has the driver installed, I needed to run JollysFastVNC to get ScreenRecycler to give me a second display. I was using ARD (and still do), which when I then reconnected showed me the whole desktop, with a menu enabling me to choose which display (or both) to view. I chose to view both displays for now.

I then loaded up the Displays preference pane, and moved the menu bar to the ScreenRecycler display.

I made the ScreenRecycler display run in a higher resolution (1280×960, so that it fits nicely onto my external monitor on my laptop at full-size). I then went to the EyeTV preferences, and made sure the full-screen display went onto the “real” monitor. This apparently has the side effect that quicktime movies will also play on this monitor, so that’s quite good.

Finally, I made new Live TV and Recording open in a new window. This enables me to edit a movie while Jaq is watching another. It does, however, mean that it is a little cumbersome to switch between tuners (need to view both monitors, and do some more swizzling), but it’s workable. It was always hard to switch tuners anyway, at least with the Apple Remote.

This makes for a fairly cool setup. I’m fiddling a little more before I buy ScreenRecycler (like, does it work better upon startup?), but it looks pretty promising.

Well, not mine, exactly.

Flinders Learning Online doesn’t render properly in Safari 4 (Developer Preview). It doesn’t display the sidebar, which has quick access to topic information.

It basically makes it unusable.

I think the system is the Blackboard Learning System, or something similar.

I can’t post this in ecto - I think the Safari 4 DP is fucking with that too.

Anyway, if I log into the BLS using any application that uses WebKit as its renderer, I see the following:

If I resize the window, it fixes itself:

By default, Safari in Leopard doesn’t show tabs.

defaults write com.apple.Safari AlwaysShowTabBar 1

Now, it does.
