Browser WAR

Browser Warfare: Shiretoko To Wrestle IE, Chrome
The next version of Firefox is on its way; you can download and test the alpha release of Shiretoko.



Mozilla, the creator of Firefox, has released the second alpha of Firefox's new version -- code named Shiretoko. The new browser is available for Linux, Mac and Windows. Looks wise, there is a big facelift in the new browser. Although it looks close to IE 7 or 8, but it is not as innovative as Chrome. Shiretoko is built on the pre-release version of the Gecko 1.9.1 platform, which forms the core of rich Internet applications such as Firefox. To download Shiretoko, click here.
But, keep in mind, this is a bleeding edge release intended for developers and testers only. Current users of Mozilla Firefox should not use Shiretoko Alpha 2. If you want to only try this out then only download it. This Alpha of Shiretoko, Gecko 1.9.1, introduces several new features which include support for the HTML 5

Mass Effect Review

Streamlined combat and numerous minor improvements make this great game even better.

The Good

  • All the awesome stuff that made Mass Effect on the 360 great   
  • Tech/Biotic power hotkeys make combat fast and fluid   
  • Numerous small improvements add up nicely.

The Bad

  • Still hampered by graphical hitches   
  • Brief, intermittent load screens.

When Mass Effect was originally released last November on the Xbox 360, it unveiled a vast, beautiful galaxy populated by diverse, fascinating alien races. Players stepped onto this stage as Commander Shepard, a hero at the vanguard of humanity's ascension in the arena of galactic politics, and thus began an epic story bolstered by engaging characters and rich, branching dialogue. Exciting combat and robust skill management completed the package, but it was not without flaws. Many small issues have been addressed in the PC release, and the result is a more streamlined, more playable version of one of the best role-playing games in recent memory.

The bulk of Mass Effect remains the same, so for our thoughts on the story, character customization, dialogue, quest structure, and combat abilities, please read our review of the 360 version. This review will focus on the PC experience and how it differs from console play.

None of the changes are drastic overhauls, but they do have an appreciable effect on the gameplay. One of the biggest tweaks is to the combat screen, along with squad commands which you can now issue inidividually. Pressing the space bar will bring up a heads-up display where you can change weapons or powers and issue commands to your squad. Odds are you'll use this pause very rarely, because your weapons are mapped to the function keys and your biotic/tech powers can be assigned to the number keys.

Without frequent pauses, Mass Effect further distances itself from the ponderous, tactical feel of combat in previous BioWare role-playing games. Instead, it feels like a bona fide third-person action title. Gunning down small groups of enemies while barely breaking a stride is still immensely satisfying, as is blasting your way out of larger pitched battles--only now you can unleash multiple tech or biotic attacks on the fly. You can dart out from cover, take down enemies' shields, and explode their weapons--all while shooting them--and be back behind cover in a matter of seconds. The real reward of this faster, more fluid action is the sense of power it imbues. Wielding your formidable abilities with ease really makes you feel like the badass warrior you were meant to be, and it makes combat more exciting and fun.

Unfortunately, all those tech and biotic power animations flying around can cause the frame rate to suffer on less than godly computers. This will really only happen during battles with numerous foes, and though it isn't much more than a brief stumble, it's distracting. Slightly more distracting are the frequent in-game load screens. Masked by long elevator rides on the 360, load times have actually decreased in length but increased in frequency for the PC version. Elevator rides are shorter, but you'll often be ambushed by a two- to four-second pause (the screen dims and a small "loading" icon appears) when you're coming up on a battle or entering a new area. Again, these pauses are brief enough that they don't bring things to a screeching halt, but they are a bit of a nuisance.

A few other tweaks have positive effects on the game. The inventory system is much easier to manage with a mouse and keyboard, and long lists of items won't reset to the top every time you sell something near the bottom. The Mako vehicle sequences are easier to manage thanks to the implementation of dedicated forward and reverse buttons in place of the 360 version's viewpoint-dependent controls. A new hacking and decrypting minigame, in place of the old button-matching one, is both more interesting and more suited to the game: You must move a small arrow through concentric circles to reach the core while avoiding stationary and rotating barriers. It's generally easy to accomplish once you get the hang of it, but the time limit and tricky perspective shifting help keep it entertaining. Keyboard hotkeys allow quick access to the map and squad upgrade screens, and the quicksave button is a great way to ensure you won't have to do too much backtracking. They aren't big changes, but the aggregate benefit is definitely noticeable.ystem. In the 360 version, you have to temporarily pause the action to use any weapons or biotic/tech powers beyond the one you currently have equipped. On the PC, this pause is still available, but weapons and powers have been consolidated onto one s

All the things that made Mass Effect great on the 360--the story, the conversations, the galaxy, the combat, the soundtrack, and the characters--are still great on the PC. The changes that have been implemented don't radically alter the game in any way, but they have enough of a positive impact to make it easy to recommend the PC version over the 360 version. On top of that, BioWare is offering the downloadable expansion "Bring Down the Sky" free to PC players, though at the time of this review that content was not yet available. Whether you're a seasoned Spectre looking to suit up again, or a newcomer who has never set foot on the Normandy, the refined PC version is your best choice for experiencing this excellent game

Cryptography Lesson 3

3. TYPES OF CRYPTOGRAPHIC ALGORITHMS

There are several ways of classifying cryptographic algorithms. For purposes of this paper, they will be categorized based on the number of keys that are employed for encryption and decryption, and further defined by their application and use. The three types of algorithms that will be discussed are (Figure 1):

  • Secret Key Cryptography (SKC): Uses a single key for both encryption and decryption
  • Public Key Cryptography (PKC): Uses one key for encryption and another for decryption
  • Hash Functions: Uses a mathematical transformation to irreversibly "encrypt" information



Big Bang Theory

Big Bang Theory - The Premise
The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something: our universe. The big bang theory is an effort to explain what happened during and after that moment. 

According to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago. What is a "singularity" and where does it come from? Well, to be honest, we don't know for sure. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of "black holes." Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of infinite density are called "singularities." Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something - a singularity. Where did it come from? We don't know. Why did it appear? We don't know. 

After its initial appearance, it apparently inflated (the "Big Bang"), expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe. It continues to expand and cool to this day and we are inside of it: incredible creatures living on a unique planet, circling a beautiful star clustered together with several hundred billion other stars in a galaxy soaring through the cosmos, all of which is inside of an expanding universe that began as an infinitesimal singularity which appeared out of nowhere for reasons unknown. This is the Big Bang theory.

Big Bang Theory - Common Misconceptions
There are many misconceptions surrounding the Big Bang theory. For example, we tend to imagine a giant explosion. Experts however say that there was no explosion; there was (and continues to be) an expansion. Rather than imagining a balloon popping and releasing its contents, imagine a balloon expanding: an infinitesimally small balloon expanding to the size of our current universe. 

Another misconception is that we tend to image the singularity as a little fireball appearing somewhere in space. According to the many experts however, space didn't exist prior to the Big Bang. Back in the late '60s and early '70s, when men first walked upon the moon, "three British astrophysicists, Steven Hawking, George Ellis, and Roger Penrose turned their attention to the Theory of Relativity and its implications regarding our notions of time. In 1968 and 1970, they published papers in which they extended Einstein's Theory of General Relativity to include measurements of time and space.1, 2 According to their calculations, time and space had a finite beginning that corresponded to the origin of matter and energy."3The singularity didn't appear in space; rather, space began inside of the singularity. Prior to the singularity, nothing existed, not space, time, matter, or energy - nothing. So where and in what did the singularity appear if not in space? We don't know. We don't know where it came from, why it's here, or even where it is. All we really know is that we are inside of it and at one time it didn't exist and neither did we.

Big Bang Theory - Evidence for the Theory
What are the major evidences which support the Big Bang theory?

  • First of all, we are reasonably certain that the universe had a beginning.
  • Second, galaxies appear to be moving away from us at speeds proportional to their distance. This is called "Hubble's Law," named after Edwin Hubble (1889-1953) who discovered this phenomenon in 1929. This observation supports the expansion of the universe and suggests that the universe was once compacted.
  • Third, if the universe was initially very, very hot as the Big Bang suggests, we should be able to find some remnant of this heat. In 1965, Radioastronomers Arno Penzias and Robert Wilson discovered a 2.725 degree Kelvin (-454.765 degree Fahrenheit, -270.425 degree Celsius) Cosmic Microwave Background radiation (CMB) which pervades the observable universe. This is thought to be the remnant which scientists were looking for. Penzias and Wilson shared in the 1978 Nobel Prize for Physics for their discovery.
  • Finally, the abundance of the "light elements" Hydrogen and Helium found in the observable universe are thought to support the Big Bang model of origins.

Big Bang Theory - The Only Plausible Theory?
Is the standard Big Bang theory the only model consistent with these evidences? No, it's just the most popular one. Internationally renown Astrophysicist George F. R. Ellis explains: "People need to be aware that there is a range of models that could explain the observations….For instance, I can construct you a spherically symmetrical universe with Earth at its center, and you cannot disprove it based on observations….You can only exclude it on philosophical grounds. In my view there is absolutely nothing wrong in that. What I want to bring into the open is the fact that we are using philosophical criteria in choosing our models. A lot of cosmology tries to hide that."4 

In 2003, Physicist Robert Gentry proposed an attractive alternative to the standard theory, an alternative which also accounts for the evidences listed above.5 Dr. Gentry claims that the standard Big Bang model is founded upon a faulty paradigm (the Friedmann-lemaitre expanding-spacetime paradigm) which he claims is inconsistent with the empirical data. He chooses instead to base his model on Einstein's static-spacetime paradigm which he claims is the "genuine cosmic Rosetta." Gentry has published several papers outlining what he considers to be serious flaws in the standard Big Bang model.6 Other high-profile dissenters include Nobel laureate Dr. Hannes Alfvén, Professor Geoffrey Burbidge, Dr. Halton Arp, and the renowned British astronomer Sir Fred Hoyle, who is accredited with first coining the term "the Big Bang" during a BBC radio broadcast in 1950.

Big Bang Theory - What About God?
Any discussion of the Big Bang theory would be incomplete without asking the question, what about God? This is because cosmogony (the study of the origin of the universe) is an area where science and theology meet. Creation was a supernatural event. That is, it took place outside of the natural realm. This fact begs the question: is there anything else which exists outside of the natural realm? Specifically, is there a master Architect out there? We know that this universe had a beginning. Was God the "First Cause"? We won't attempt to answer that question in this short article. We just ask the question:

Does God Exist?
