Google silently added a new feature that allows searching within a site to search results. This could have normally been done with some well crafted search queries, but this is much nicer. (the screen shot will make this clear)
While this is a awesome feature, it has some sites mad because it will detour people from using their crappy on-site search features, which serve up their own ads and surely don't show competitor's ads.

RFID Credit Cards
RFID is becoming more popular for many things. Credit cards using RFID technology sporting names like 'EZ Pass', 'quick pass', and 'speed pass' are growing. A recent Boing Boing <video netcast episode> is re-raising concerns about the security of such cards.
An older <The New York Times report> featured tests on 20 cards from Visa, MasterCard and American Express, showed that the data was being broadcast in plain text. This data frequently includes the card holder's full name, sometimes even the card number and expiration date.
A common misconception is that RFID is totally insecure by nature. This isn't true. RFID's are just a family of inexpensive devices that broadcast via radio frequencies. Other than their price, these devices are most notable for their tiny size and ability to be self-powered. These devices can capture power from the radio frequency of a requesting device, powering it's self, to make a radio frequency reply.
This misconception comes from frequent news headlines where a poor attempt, or no attempt, was made to protect the data or signals a RFID made. These signals are easily captured, but encryption techniques can be used to protect this data. Designers frequently don't bother.
In some cases, like this credit card situation, an ideally secure encryption scheme may require more elaborate equipment for legitimate readers, possibly an expensive central payment system. This could defeat the entire purpose of making transactions fast.
Some effort should be made using one of many encryption techniques to protect this data. Although the card number maybe be useless without the security code, a plain text card holder's name is surely a bad idea.
A Boing Boing TV <video netcast episode> claims a suitable RFID reader can be purchased for as low as $8 from eBay. Some lady with her hair dyed till its falling out, and a dude who has never washed his hair, demonstrate reading a card through your pocket with a similar device. Their demonstration revealed that the full goods may still be broadcast in plain text by these type of cards.

Lingering VCL Bof exploit
A buffer overflow exploit vulnerability was found in the popular <VideoLAN VLC Media Player> in the parsing of subtitle files. The last release, VLC 0.8.6e was supposed to fix this along with some other issues, but this issue is <reported> to still exist.
The simple fix is to not process untrusted subtitles using VLC. Alternatively you could use a <nightly build>, all though you may run into a bug or stability issues.

Accessing 'Must Sign Up to View' sites
More and more sites try to capture you as a repeat visitor from your casual viewing of their site by forcing you to create an account to view or download their content. We will list a few techniques and services which will help you circumvent this annoying process.
There is a ton of additional services/techniques more than we will list. Feel free to post your favorite in the comments. No account or sign up is required to post comments. The best technique to use may vary by site and the content you are after, but in general the following suggest should be considered in order.
BugMeNot is a site that allows people to share login accounts for accessing sites.

<BugMeNot Firefox Add On>
Web caches are saved copies of web pages. They can let you view sites who are no longer accessible and sometimes can cache sites not normally accessible.
Google automatically shows a link to cached versions of search results as shown above.
<More about Google caches>
The Wayback Machine (referring to the time machine in 'The Rocky and Bullwinkle Show' cartoon) is another web caching service.
<Internet Archive: Wayback Machine>
User Agent spoofing is another possible technique. When a web page is requested by your browser some information is sent along. Part of that information is your <user agent> witch identifies your browser and possibly your operating system and their versions. This is to help websites display properly across many software clients and platforms.
Web search engines have 'spiders' crawling the web indexing web sites. To comply with standards and prevent getting low search engine scores web sites typically do what they can to allow web spiders a larger amount of access to content. Spiders typically are identified by their user agent string. So, by spoofing a web spider's user agent string, you may have some less restricted access to content of sites. The following tools will help you spoof your user agent.
<Firefox add on: User Agent Switcher>
(this may require a quick <Google search of 'user agent list'> to find a list of common user agents to load into the tool.)
<Be The Bot> A web based proxy meant to request pages using a Google or Yahoo spider's user agent string.

Firefox 3 Browse On A Diet
Firefox 3 puts a nice effort into further reducing memory consumption. Initial testing of Firefox 3 Beta 4 shows a dramatic change. In the mist of Internet Explorer 8's less than fantastic standards progress, along with rumors of the IE8 beta being horribly buggy, Firefox's competitive outlook seems good. 
Memory change highlights:
- Reduced memory fragmentation
- Cycle collector
- Tuned Caches
- Image data storage adjustment
- Leak cleanups
