Interested users can perform a text search which can either be broad or very specific. Advanced search parameters allow to specify a timeframe, place of publication, publication section, frequency and language among other parameters. It is furthermore possible to only search for information that are freely available. Free newspaper articles are available instantly while those that are not free require a registration on the site and the purchase of a 24-hour or 7-day pass which are good for 100 and 200 articles during that time (the website selling the passes was unavailable at the time of writing so no information on the pricing scheme)

A free search will only yield a few results compared to a full text search. Searching for Jack the Ripper will for instance displays 23 free results but 2035 free and pay to view results. All contents of the newspaper library are usually available for people in UK higher and further education and in some public libraries.

Newspaper articles can be printed and marked as favorites. The British Newspaper archive can be accessed freely by people from all over the world.

For most of us (at least for me), that research involves the fun little dance of switching between Microsoft Word and the Internet, constantly reading, writing, losing my place, cursing the world, crying uncontrollably, and then getting back to work. But I digress.

One of the best tools out there, of the many I’ve tried to avoid that vicious cycle, is WebNotes. I use it constantly as a student and a professional, and it offers the most features and best usability of any application out there.

WebNotes, at its most basic, is an annotation tool. The first step is to install the toolbar (which works in Firefox and Internet Explorer), or the bookmarklet (which works in pretty much every browser, but with a couple fewer features). When you visit a website, the WebNotes software lets you can either highlight the text on the page, or make sticky notes with comments on the page. Everything you annotate is automatically added to your WebNotes organizer, for easy access later.

Once you’ve annotated a few pages, check out the WebNotes organizer. From there, you can either see the Web pages in their original form, view your highlights and comments on top of the page, or see only your markups. You can also search through your highlighted text and annotations, which makes finding that killer quote you came across an impressively easy proposition.

You can share notebooks, or individual notes (the organization and filing features of WebNotes make sharing them easy), which makes WebNotes great for collaborating on research within a group. There’s no emailing files necessary, no trying to figure out which version is most up-to-date; instead, all your research lives in one constantly-updated place.

For the more professional users, there’s the ability to create a “Report,” which is a well-designed aggregation of all your notes and highlights on a given subject. I’ve used it for giving presentations, or just summarizing research to someone else – it’s much more useful than I initially thought it would be.

The bottom-line of WebNotes is that it streamlines all your research. One, everything goes into one place, meaning there’s no hunting through twelve different Word documents to find what you want. Two, there’s no copy and paste – just highlight or comment, and everything gets saved automatically. The best thing about WebNotes, though, is that it lets you avoid the inevitable hunt through a page you know is useful, but that you can’t for the life of you figure out why.

A few weeks ago, WebNotes launched a “Pro” version, which adds some serious functionality to WebNotes. The biggest update, at least in my own use, is that WebNotes Pro lets you highlight and comment on PDF files. Particularly in school, I do a ton of reading PDF’s, and hate changing between the PDF and Word constantly so I can take notes. With WebNotes, that’s all avoided, and PDF markups go right into my organizer. (If you love the idea of PDF markup, but don’t want to use all that WebNotes has to offer, give Foxit Reader a look – it’s got all the markup love you could want.)

The Pro version also offers better support, and Multi-Color highlighting. It’s aimed squarely at professionals and students who do a lot of research from a lot of different sources, and WebNotes wants to be the source for all your research and informational bookmarking. For me, personally, it’s become indispensable in both cases.

The Pro version costs $9.99/month, but there’s a 50% discount for students who use the promo code “student101″. For gHacks readers, however, there’s an even better deal:

3 FREE months of the full, WebNotes Pro interface. The first 50 people to click this link will get three months free of the Pro features, to test to your heart’s content.

If you don’t want the added features (and the price tag), you’ll be reverted to the free version of WebNotes – which is pretty great itself – after three months is up.

What do you think of WebNotes? Is there a better application out there?

Google adds columns to the spreadsheet that differ depending on the search term. A search for people for example will reveal names, images, descriptions and their dates of birth and death with the option to add new suggested columns at the end of the spreadsheet which can include notable ideas, main interests or schools / interests. A search for metal on the other hand reveals information about the density, cas number, melting point, atomic number or crystal system.

Google Squared is therefor an interesting option when researching information that can be grouped. The conventional way of looking up all American Presidents would be to either perform a search on a search engine and look at the first results that come up or directly visit an encyclopedia like Wikipedia for the information. Most result pages however contain additional text and it is up to the researcher to find the right information.

There is however on problem associated with Google Squared which makes the concept prone to error: There is no quality control. Google Squared fetches information from all over the web which can lead to errors. Take a look at the results in the picture above. The spreadsheet tells us that the philosopher Plato was born on November 7, 1964. A click on that specific entry displays additional birth days including 424-423 BC of Wikipedia. Plato’s birth year taken from Wikipedia’s is however marked as low confidence data in this case.

While it is easy to spot such obvious flaws it becomes more difficulty. Who can say that the density of Platinum is really 21.45, that the maximum speed of the German WWII tank destroyer Jagdpanther was indeed 46 km/h or that Saturn’s orbital period is 29.46 years.

This means that it is always advised to find at least one additional source of information that backs up the information presented by Google Squared.

Then I spotted a post about PersonalBrain over at Rarst’s website entitled Mapping stuff in PersonalBrain and it seemed to be exactly the software that I was looking for. Both applications are written in Java and available for Windows, Linux and Macintosh.

The elements are called thoughts and originate from one home thought in PersonalBrain. Each thought, except for the home thought, consists of a name and at least one link to another node in the system. The user can write down notes for every thought on the map that can contain additional information. There is also the option to add attachments like text documents or web links to each node. Additionally users can add tags, set types and colors for each node separately.

The option to add links as attachments to nodes and the ability to write down additional notes are invaluable for my research. Other users might find other features more interesting but those two are the main ones why I have decided to switch the mind mapping software.

PersonalBrain comes with a lot of build in customizations like themes that can be applied to change the looks of the mind map. Something that might appeal to users who use PersonalBrain for presentations but nothing that adds real value to the application. More interesting than that are the options to filter and search nodes of the mind map.

Another interesting feature is the export function. It is possible to export the mind map as simple html or html with XML Information, the former providing simple access to the core information while the latter displays a static mind map.

Words are chosen by probability and suggest alternatives which more often than not make more sense than the first word. This introduces a new technique to spy on users without having to actually access the computer at all, all that is needed is a good view of the hands and the measure of the keyboard.

The second spy tech could come right out of the latest James Bond movie. The researchers at Saarland University managed to write a computer algorithm that is capable of interpreting reflections of the computer screen on objects. The quality of the telescope plays an important role, a normal $500 telescope was able to read 12 point fonts of a reflection that was 5 meters away from the computer and 198 point fonts from a distance of ten meters.

A more powerful Dobson telescope for $27500 was able to yield the same results from a maximum distance of 30 meters. Other tests allowed the researchers to view the monitor from a white wall that was 2 meters away from the computer screen.

The best way to defeat the techniques ? Don’t access a computer in public, always close the curtains when working with your computer and make sure no cameras are installed in the room with a computer.

The first project demonstrated a digital whiteboard, something that sells for several thousand Dollars, emulated by the Wiimote and additional hardware that do not cost more than $10. The software used in the demonstration can be downloaded from the researchers website and it actually has been downloaded about 500.000 times.

The other project demonstrated a head mounted 3d- viewer. This system was also using the Wiimote and some additional hardware. He mentioned that this technique will be included in a game by Electronic Arts as an Easter Egg.

As of September 2007, Nintendo has sold over 13 million Wii game consoles. This significantly exceeds the number of Tablet PCs in use today according to even the most generous estimates of Tablet PC sales. This makes the Wii Remote one of the most common computer input devices in the world. It also happens to be one of the most sophisticated. It contains a 1024×768 infrared camera with built-in hardware blob tracking of up to 4 points at 100Hz. This significantly out performs any PC “webcam” available today. It also contains a +/-3g 8-bit 3-axis accelerometer also operating at 100Hz and an expandsion port for even more capability. These projects are an effort to explore and demonstrate applications that the millions of Wii Remotes in world readily support.

The homepage of Johnny Lee contains another video that is demonstrating how it is possible to track fingers with the Wiimote.

Hyperwords is giving you access to commands and searches that are able to interact with words on every page that can be accessed with Firefox. Just mark text on a website and the Hyperwords menu pops up automatically with a lot of choices such as translating the text, looking it up at various sites and maps, converting numbers or emailing it.

It is possible to change the default action that is required to make the Hyperwords menu appear which I would recommend. I sometimes mark text for others reasons which is why I changed it to appear only when I mark text and press F2 as well.

This extension is a great asset for everyone who is working with Firefox. It does not really matter if you are a blogger, researching information for the University or a working on sites that are in a language that you do not speak fluently. Should be useful for almost everyone out there.
