Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !

Bruce Schneier ( //; born January 15, 1963) is an American cryptographer, computer security specialist, and writer. He is the author of several books on general security topics, computer security and cryptography, and is the founder and chief technology officer of BT Managed Security Solutions, formerly Counterpane Internet Security, Inc.
A son of Martin Schneier, a Brooklyn Supreme Court judge, Bruce grew up in Flatbush, attending P.S. 139 and Hunter High School. After receiving a physics bachelor's degree from the University of Rochester in 1984, he went to the American University in Washington, D.C. and got his master's degree in computer science in 1988. He was awarded an honorary Ph.D from the University of Westminster in London, England in November 2011. The award was made by the Department of Electronics and Computer Science in recognition of Schneier's 'hard work and contribution to industry and public life'.
In 1994, Schneier published "Applied Cryptography", which details the design, use, and implementation of cryptographic algorithms. More recently he published "Cryptography Engineering", which is focused more on how to use cryptography in real systems and less on its internal design. He has also written books on security for a broader audience. In 2000, Schneier published Secrets and Lies: Digital Security in a Networked World. In 2003, Schneier published Beyond Fear: Thinking Sensibly About Security in an Uncertain World.
Schneier writes a freely available monthly Internet newsletter on computer and other security issues, Crypto-Gram, as well as a security weblog, Schneier on Security. The weblog started out as a way to publish essays before they appeared in Crypto-Gram, making it possible for others to comment on them while the stories were still current, but over time the newsletter became a monthly email version of the blog, re-edited and re-organized. Schneier is frequently quoted in the press on computer and other security issues, pointing out flaws in security and cryptographic implementations ranging from biometrics to airline security after the September 11 attacks. He also writes "Security Matters", a regular column for Wired Magazine.
Schneier revealed on his blog that in the December 2004 issue of the SIGCSE Bulletin, three Pakistani academics, Khawaja Amer Hayat, Umar Waqar Anis, and S. Tauseef-ur-Rehman, from the International Islamic University in Islamabad, Pakistan, plagiarized an article written by Schneier and got it published. The same academics subsequently plagiarized another article by Ville Hallivuori on "Real-time Transport Protocol (RTP) security" as well. Schneier complained to the editors of the periodical, which generated a minor controversy. The editor of the SIGCSE Bulletin removed the paper from their website and demanded official letters of admission and apology. Schneier noted on his blog that International Islamic University personnel had requested him "to close comments in this blog entry"; Schneier refused to close comments on the blog, but he did delete posts which he deemed "incoherent or hostile".
To Schneier, peer review and expert analysis are important for the security of cryptographic systems. Mathematical cryptography is usually not the weakest link in a security chain; effective security requires that cryptography be combined with other things.
The term Schneier's law was coined by Cory Doctorow in his speech about Digital Rights Management for Microsoft Research, which is included in his 2008 book Content: Selected Essays on Technology, Creativity, Copyright, and the Future of the Future. The law is phrased as:
Any person can invent a security system so clever that he or she can't imagine a way of breaking it.
Few false ideas have more firmly gripped the minds of so many intelligent men than the one that, if they just tried, they could invent a cipher that no one could break.
Schneier is critical of digital rights management (DRM) and has said that it allows a vendor to increase "lock in." Proper implementation of control-based security for the user via trusted computing is very difficult, and security is not the same thing as control.
Schneier has said that homeland security money should be spent on intelligence, investigation, and emergency response. Defending against the broad threat of terrorism is generally better than focusing on specific potential terrorist plots. According to Schneier, analysis of intelligence data is difficult but is one of the better ways to deal with global terrorism. Human intelligence has advantages over automated and computerized analysis, and increasing the amount of intelligence data that is gathered does not help to improve the analysis process. Agencies that were designed around fighting the Cold War may have a culture that inhibits the sharing of information; the practice of sharing information is more important and less of a security threat in itself when dealing with more decentralized and poorly funded adversaries such as al Qaeda.
Regarding PETN- the explosive that has become the terrorists’ weapon of choice- Schneier has written that only swabs and dogs can detect it. He also believes that changes to airport security since 11 September 2001 have done more harm than good and defeated former head of the Transportation Security Administration, Kip Hawley, in an Economist online debate by 87% to 13% regarding the issue.
Schneier has criticized security approaches that try to prevent any malicious incursion, instead arguing that designing systems to fail well is more important. The designer of a system should not underestimate the capabilities of an attacker; technology may make it possible in the future to do things that are not possible at the present. Under Kerckhoffs's Principle, the need for one or more parts of a cryptographic system to remain secret increases the fragility of the system; whether details about a system should be obscured depends upon the availability of persons who can make use of the information for beneficial uses versus the potential for attackers to misuse the information.
Schneier is a proponent of full disclosure, i.e. making security issues public.
Schneier and Karen Cooper were nominated in 2000 for the Hugo Award, in the category of Best Related Book, for their Minicon 34 Restaurant Guide, a work originally published for the Minneapolis science fiction convention Minicon which gained a readership internationally in science fiction fandom for its wit and good humor.
Schneier has been involved in the creation of many cryptographic algorithms.
