Enable missing disclosure triangles in Finder

The problem is with the arrangement chosen for the list view.  Using any of the following methods, choose Arrange By | None:


  • The View menu from menubar
  • The gear icon in the Finder window
  • The contextual menu (right + click mouse button)


The Finder in Mac OS X is the application is always running and provides access to the file system of the computer.  This is the Windows Explorer on Windows systems, or something like Nautilus on Gnome-based Linux systems.  The primary interface is a folder paradigm that presents files and folders in a number of different views.

On the Mac, these views are icons, list, columns, and Cover Flow.  To the Finder, the list view is a "stacked" presentation of the files with alternating background colors and a nice feature Apple calls a "disclosure triangle."  This control is present on directory items, and when clicked, will either expand the listing to show a nested view of the contents of that folder or contract an already expanded listing.

The problem is that sometimes these disclosure triangles aren't present.


Disclosure triangles not present.

Setting the Arrange By option to "None" will restore the disclosure triangles.

Skype Now Supports Emergency Calls In the US

With the latest round of updates to Skype , it was noticed today that the instant messaging and VoIP phone service now supports emergency calling in the United States. The release notes for the most recent update to the Android version of Skype indicated that the service now allows calls to be made to US emergency calling systems via 911.  Telephony services like Skype, Google Voice , and Vonage typically don't offer this emergency calling ability without some sort of intermediate step like deferring to the phone's default dialer, as is the case with Voice, or setting up a physical address location ahead of time which is how Vonage handles it. The indication is that Skype will handle the 911 calls natively, but when verifying with an account that does not have a Skype phone number assigned to it, it was found that the instructions in the FAQ explaining how to turn on emergency calling are not accurate.

PHP built-in webserver and IPv6 addresses

Though it's difficult to confirm around the Web, it appears as though the IP address scheme the built-in PHP server uses depends on the host name that's provided.  If a fully-qualified domain name (FQDN) is used, such as server.domain.tld, then the built-in server will be listening for IPv6 based requests.  If the server is started with an IPv4 address identified as the host, then it will naturally listen for IPv4 based requests. The closest to anything official around the Web was a comment in the PHP docs that only seeded this conclusion, at best.  But here it is in any case.

Allow Windows authentication using SQL Server driver with DBeaver

DBeaver will allow Microsoft Windows single sign on access when connecting to Microsoft SQL Server using the SQL Server driver (rather than jTDS ).  From the driver properties settings, set the integratedSecurity flag to true . Open the Connection configuration panel and choose the Driver properties section. Set the integratedSecurity flag to true . A subtle, but important step is to not provide username and password credentials to the connection.
