From Lux-Sci: Real-world vulnerability? What is  affected by BEAST?

This problem can affect people browsing secure web sites, allowing eavesdroppers to gain full access to your accounts on those web sites under certain conditions.  It does not affect

It does affect:

  • Accounts you may have with secure web sites that you login to, like PayPal, LuxSci, Gmail, Bank of America, Facebook, etc.

 

Solution:

It is not yet feasible to use a browser or webhost that supports TLS 1.2. For now, here is LuxSci's advice:

The Take Away Message

People should always be concerned and aware of security as the landscape changes constantly.  We think that beyond the need to upgrade and to implement software fixes, consider the following:

  • We should actually use SSL and TLS whenever possible. Insecure sites puts our browser and computer at risk, as we have no control over what malicious third party may inject into our browsing session.  SSL and TLS actually protect us from that threat.
  • When going to secured web sites, it is best to start in a new browsing session or one that has only visited other secure (https://)  sites.
  • Make your home page a secure site and your other secure sites easily-accessed via bookmarks
  • Use a separate web browsers for normal insecure browsing and for access to your secure sites.
  • Keep your software, web browsers, operating system, anti-virus, and other components up to date.

Mac OS X: Removing information about completed print jobs

Posted by Paul Gurney

In Mac OS X v10.5 and later, it's impossible to remove (clear) information about completed print jobs without this tip.

Products Affected:   Mac OS Printing/Fax (any version), Mac OS X 10.5, Mac OS X 10.6, OS X Lion

If you would like to clear the list of completed print jobs for any print queues (which will also clear any pending or active print jobs), Apple says to: Delete the printer, then add it again.

 

Wow, that's a bit of a hassle. Instead, you can Clear the entire print queue in OS X with a Terminal command. Launch Terminal and type:

cancel -a -

Preventing future print jobs from appearing in the completed jobs list (advanced)

If you would like to prevent all future print jobs from being included in the list of completed jobs, open Terminal and execute this command:

cupsctl PreserveJobHistory=No

You can later restore the default behavior of retaining a list of completed print jobs by resetting the printing system, or by opening Terminal and entering the command:

cupsctl PreserveJobHistory=Yes

Too bad Apple didn't make the Delete button actually work in the Printer Manager!

CSS 3 – Box Shadow properties

Posted by Paul Gurney

The box-shadow property in CSS3 allows a comma-separated list of shadow attribute values.

These specify, in order, the horizontal offset, vertical offset, optional blur distance and optional spread distance of the shadow);

Then,  an optional color value and an optional ‘inset‘ keyword.

Inset lets you create an inner shadow, rather than the default outer shadow.

Examples:

  box-shadow: 5px 5px;
  box-shadow: 5px 5px 15px #888;
  box-shadow: inset 2px 2px 2px 2px black;
  box-shadow: 5px 5px #666, -12px -12px #f4f4f4, 0px 0px 15px 15px #cc6600;

These are supported in newer browsers.

Mac Users: Configuring new Mail Accounts in Thunderbird 3

Posted by Paul Gurney

Creating a new Account for which you want to use the Global Inbox

When you create a new POP mail account in Thunderbird, the Account Wizard may ask if you want to use the Global Inbox for that account. If it does that (and you want a global inbox), check that feature. If it doesn't ask (recent versions don't) then you need to select "Global Inbox (Local Folders account)" in Preferences -> Advanced -> Config Editor .

Try to do that before Thunderbird checks for new mail to avoid complications.

 

If you often create new accounts, you can set the default in the Account Wizard by setting the preference :

mail.accountwizard.deferstorage

to

true

(to check the box by default), or false (to clear the box by default).

 

In a new Thunderbird profile this preference does not exist initially, so you must create it as a new Boolean preference.

On the Mac, right-click in the editing window, and choose "New..."

 

Changing the Global Inbox setting for an existing account

To change the Global Inbox setting for an existing account, you need to follow three simple steps.

 

Change the destination Inbox

Go to "Tools -> Account Settings -> Server Settings" and click on the "Advanced" button. A dialog box will then pop open.

To set the account to use the Global Inbox, select "Global Inbox (Local Folders Account)" and click "OK".

Important: if the account already has messages in the Inbox or other folders, you should copy or move these messages into Local Folders before setting the account to use the Global Inbox. If you don't copy or move the messages into Local Folders and you set the account to use the Global Inbox, the account will no longer be displayed in the folders pane and you will not be able to access those messages unless you go back and undo the Global Inbox setting.

To set the account to not use the Global Inbox, select either "Inbox for this server's account" or "Inbox for different account" and click "OK".

Check settings for other folders and filters

After you have changed the account's setting for which Inbox to use, see if any of the following need to be changed:

  • Go to "Tools -> Account Settings -> Copies & Folders", and look at the destination folders for Sent, Drafts, and Templates. Make sure that the messages for each will be stored in your preferred folder locations.
  • If you are using junk-mail filtering for the account, go to "Tools -> Account Settings -> Junk Settings" and verify that the folder selected for Junk messages is the one you want to use.
  • If you have set up any filters, go to "Tools -> Message Filters" and make sure that they will work properly with your new Inbox configuration. Especially important if you are changing an account so that it will start using the Global Inbox: if you have set up any filters that sort messages into any of the folders for the account, you should disable/delete those filters or change the destination folders.

Exit and restart Thunderbird

Important: exit Thunderbird and restart before downloading mail into any account whose Inbox/Global Inbox setting you've changed. If you do not exit and restart, messages might continue to download into their "old" locations (e.g., into the individual account Inbox rather than the Global Inbox).

Human Costs of an iPad

Posted by Paul Gurney

From a NYTimes article titled "In China, Human Costs Are Built Into an iPad"

http://nyti.ms/Adv0Kp

“You can either manufacture in comfortable, worker-friendly factories, or you can reinvent the product every year, and make it better and faster and cheaper, which requires factories that seem harsh by American standards,” said a current Apple executive.

“And right now, customers care more about a new iPhone than working conditions in China.”

Important exposé.
