Infineon SLE 66 CL PE chip achter de nieuwe “veiliger” OV Chipkaart is reeds gehacked – Reactie | Pro | Tweakers.net

Posted by jpluimers on 2011/10/07

Security by obscurity maakt het alleen maar lastiger, maar uiteindelijk gaat de nieuwe veiliger OV Chipkaart ook gehacked worden, zeker nu de achterliggende Infineon SLE 66 CL PE chip gehacked is.

#tzdb Civil Suit Filed, Involving the Time Zone Database: Arthur David Olson and Paul Eggert need help (via Slashdot)

Posted by jpluimers on 2011/10/07

The tzdb (Timezone Database) is an important database of current and historical timezone information.

Yesterday, it became clear that a civil suit was filed on September 30, 2011 by Astrolabe over parts of the historic data in the tzdb.

As a reasult, the tzdb download and mailing list has been shut down (already archived at the WayBack machine).

This might be speculative, but I find the coincidence with the plans of the IETF taking over the maintenance of the tzdb, as well as the sudden number of edits on the Wikipeda tzdb page before the suit was filed stunning (thanks Ghostworks for pointing me to the latter).

A lot of software depends on the tzdb (Unix, Linux, Mac, Windows, IBM, you name it). As soon as you have used a timezone like “Europe/Amsterdam”, you have likely used the tzdb in one form or the other.

Arthur David Olson and Paul Eggert most likekely need help, lets hope one of the big companies helps them.

PS: When I started writing this blog post, the tz database Wikipedia page didn’t mention the law suit, now it does. But given the frequent changes mentioned above, I’m not sure which information on that page is correct or incorrect.

Why can’t I move the Program Files directory via the unattend file? – via: The Old New Thing – Site Home – MSDN Blogs

Posted by jpluimers on 2011/10/07

You cannot move the C:\Program Files directory to another volume without installing Windows on that volume.

A small abstract from the explanation by Raymond Chen: The symbiotic relation between C:\Windows\WinSxS and C:\Program Files through NTFS hard links prevents you to move C:\Program Files (nor WinSxS) to a different disk volume. Both directories need to be on the same volume because of the NTFS hard link limitation.

NTFS hardlinks do save a ton of diskspace, even though WinSxS will keep growing over time, which means you need to do some careful disk volume planning, especially on SSD drives.

Registry Search-Replace tools – correcting the havoc after a data migration

Posted by jpluimers on 2011/10/07

A while ago, I found myself in the situation where at a corporate client the user profiles had moved on the LAN. Very understandable: it was one of the migrations towards DFS. They notified this in advance, so I made backups of everything (home drive and user profile) just to make sure.

The move indeed caused all sorts of havoc, because the data was moved, but the registry was only slightly modified.

Some of the errors I got were like these:

[Internet Explorer - Search Provider Default]
A program on your computer has corrupted your default search provider setting for Internet Explorer.

Internet Explorer has reset this setting to your original search provider, Live Search (search.live.com).

Internet Explorer will now open Search Settings, where you can change this setting or install more search providers.
[OK]

and

[Desktop]
\\old-server\old-share\user-id\Desktop refers to a location that is unavailable. It could be on a hard drive on this computer, or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the Internet or your network, and then try again. If it still cannot be located, the information might have been moved to a different location.
[OK]

Below some of the ramblings on what I did to get everything working again, including registry searches when you are not allowed to run RegEdit, searching through text, and the places in the registry that had to change. Read the rest of this entry »
