] | Don't use **get\_template\_directory\_uri()**. Use **get\_template\_directory()** instead. Your code should look like this:
```
load_theme_textdomain( 'transparent', get_template_directory() . '/languages' );
$locale = get_locale();
$locale_file = get_template_directory() . "/languages/$locale.php";

29,319,123 | It appears that `CWInterface` is deprecated in 10.10 Yosemite, and it has been replaced with `CWWiFiClient`.
In `CWInterface` I would normally use the `setPower` method to disable WiFi, but I do not know of a similar method in `CWWiFiClient`.
Does anyone know how to disable WiFi with `CWWiFiClient`?
Thanks. | 2015/03/28 | [

] | Get CWInterface instance like this:
```
let _en: CWInterface! = CWWiFiClient.sharedWiFiClient().interface()
```
and now you can use the `setPower` method to disable WiFi again! | According to Apple CWInterface and setPower is still current in 10.10, but has just been modified.

] | You can use `bc` command:
```
elapsed_time_in_ms=$(echo "scale=3;$elapsed_time/1000000" | bc)
```
The `scale` basically sets the number of digits you want after the `.` | This can also be done using shell parameter expansion or via `printf`. For example, running the following two sequences one after the other printed out `1349883230.715` and `1349883230.721` in one run, and `1349884003.025` and `1349884003.032` in another.
