Windows 7 won’t boot up, Safe Mode hangs (typically at CLASSPNP.SYS), the System Recovery can’t fix (Bad Patch and AutoFailover errors) and there are no recovery points to revert back to. Sound familiar? There’s a working solution! Read the rest of this entry »

Delete and clear POSTFIX queue in one line

Oftentimes, you may need to just delete all messages in queue (for example, when your script has gone mad and generated too many messages to handle, once you’ve stopped postfix). It’s quite simple, really: Read the rest of this entry »

Touch surfaces and ubiquitous computing. I’m going through the exercise at the moment with portable touchscreen communicators and business enablers.

Three Oh Five – WordPress Upgrade are out
2011
02.08
02.08
The upgrade to 3.0.5 was resleased yesterday. From the release notes:
Two moderate security issues were fixed that could have allowed a Contributor- or Author-level user to gain further access to the site.
One information disclosure issue was addressed that could have allowed an Author-level user to view contents of posts they should not be able to see, such as draft or private posts.
Two security enhancements were added. One improved the security of any plugins which were not properly leveraging our security API. The other offers additional defense in depth against a vulnerability that was fixed in previous release.
Download and upgrade now!

Expire private images to protect privacy on the Internet?
2011
01.11
01.11
A new product over at x-pire.net (which redirects to x-pire.de) was unveiled in Germany today, with the aim of embedding expiry times and information into images so that they cannot be viewed after a certain time. In that way there should be a maximum lifespan to digital images on the web to prevent future embarassment, usage etc. At this stage, the prototype is available as plug-in for Firefox (as well as some other browsers in future), and expounds the idea of a ‘forgetful internet’ so that information is not immortal on the web.

From the WordPress Development Blog:
Version 3.0.4 of WordPress, available immediately through the update page in your dashboard or for download here, is a very important update to apply to your sites as soon as possible because it fixes a core security bug in our HTML sanitation library, called KSES. I would rate this release as “critical.” Read the rest of this entry »
Nudge, nudge, wink, wink – WordPress Upgrade
2010
12.09
12.09
… it’s time to go 0-3, I think — WordPress 3.0.3 is out – but the update is really only applicable to remote publishing-enabled systems…
WordPress 3.0.3 is available and is a security update for all previous WordPress versions.
This release fixes issues in the remote publishing interface, which under certain circumstances allowed Author- and Contributor-level users to improperly edit, publish, or delete posts.

Seems like there is an upstream cable fault (being investigated) that has caused international browsing from South Africa outward to fail.

Stuxnet lessons – and resources

11.27
Just a quick grouping of resources relating to Stuxnet resources and analysis after the targeted infections of the frequency converters of the Vaasa, Finland based Vacon (though Vacon publicly denies this) and Iranian company Fararo Paya.
The bottomline takeaway – never use default passwords (partical attack vector of the PLCs and SCADAs), and keep systems patched (4 zero-day Windows-based attacks). And don’t allow USB devices on a production network (the entry point of the 0.5Mb virus written in C and C++)… Read the rest of this entry »
Proxying all Linux Traffic – set web access for Ubuntu behind a proxy
2010
10.22
10.22
So that it’s documented… I’m using port 8080 as the default port as the likelyhood of your upstream proxy being on 8080 is high – else, typical proxy ports are, of course, 80, 800 (transpartent), 8000, 3128 (squid)
To force your server to force web traffic via a proxy, just two quick things to set – in /etc/environment, export one (or two) variables: Read the rest of this entry »
Search and view gzip’d files

You knew it already – but I keep forgetting – the power of zgrep and zcat both of which behave as their z-less counterparts.
So, to search a gzip’d file, you can simply zgrep <term> <filename.gz>, or to cat/view it, zcat <filename.gz>
Good to come back to in case of impending forgetfulness…
Intel Gigabit Ethernet Card on an old kernel?

For self-reference, mainly:
For the Intel Corporation 82574L Gigabit Network Connection on an old kernel that doesn’t have the drivers compiled into it – get the driver and

it on the platform you’re on, and to be sure (if it doesn’t get done for you) to copy to /lib/modules/2.4.36/kernel/drivers/net/ (your kernel may vary, this is an example only) Read the rest of this entry »
Your Kindle, PDFs, EPUBs, file and format conversion and you

There are two irritations when it comes to the Kindle. First of those is your collection of PDFs you bought or own that you’d like to read as a ‘book’ on the Kindle (without going through the whole long USER@[free.]kindle.com) email and Whispernet delivery process. The other is the EPUB Sony Book reader format files that you have — but that the Kindle doesn’t interpret. Here’s how to get around this. Read the rest of this entry »
Firefox: Paste HTML code from one child frame to parent text-box – src stripped
2010
09.10
09.10
Here’s something fun: use Firefox 3.6.9 to have a set of Javascript code in a child frame append HTML code to a text box in the parent frame, and content of the string is modified:
what was
<img src="foo.jpg" alt="bar" width="1" height="1" />
becomes
<img alt="bar" width="1" height="1" />
which is pretty pointless… Read the rest of this entry »
