3 Ways in Which CD Keys Are Helping Game Developers and Publishers to Fight Piracy

Peer-to-Peer networks and various other internet portals have been infamous for contributing towards piracy of video games. Developers and publishers spend a lot of time and money for coming up with the latest games. Years of research, innovation, creativity and efforts are required to build a game that appeals to the fans. The investment is usually in the order of millions of dollars. The least that the developers expect is their fair share in the revenue earned by the games.

But piracy seems to disrupt all of that. Developers have had to simply watch their hard work go to waste as people made illegal copies of the games and sold it with unauthorized keys that were pretty easy to replicate by anyone who had the right tools and just the right amount of technical understanding.

And just when things were getting worse, the games were given CD keys that were not only platform specific, but also specific for each copy of the game. Now this made it absolutely difficult for the games to be subjected to piracy. And with the developments in internet technologies, these keys are now not only used for accessing the game, but they are also used for downloading the games for consoles and desktop platforms that have cloud services. Check out the following benefits of CD keys which are in fact helping game developers to fight piracy.

CD Keys are Specific to Every Copy of the Game

Game publishers / developers are making use of advanced keys that are not only very specific to each copy of the game but they are also aligned to the specific platform that is compatible with the game. Moreover, with the games now being offered on cloud services, you need to get genuine serial codes for downloading the game. This has eliminated the possibility of piracy significantly.

Keys Once Activated Can Never Be Used Again

The one-time use feature was available for previous games also, but the possibility of using it as a base for regenerating matching keys or almost compatible keys was pretty much existent. There were also a chance that a particular serial code might work for another copy of the game. Such chances were not that frequent, but it could have worked by sheer luck. Now, CD key providers have implemented stringent quality checks, where every single key that they obtain from the publisher is verified for authenticity before it is dispatched. If someone does try to sell it off after use, then the key would be of no use. With the rising awareness about legal serial codes, customers are less susceptible to such threats as they would prefer to buy from a genuine source rather than seek out such keys from the internet.

Various Additional Perks are Provided Along with CD Keys

By providing value added perks such as discounted Downloadable Contents, season passes and assistance in queries, CD key providers are encouraging people to support authentic serial codes. Such benefits can never be provided to those who have simply ripped the keys from some forum or portal on the net.


Gaming is fun and attracts the attention of a lot of people, but it can be made even more fun if you get the real thing with all the perks and benefits. It may appear rather insignificant, but if you consider the perspective of the game developers, then the codes have the potential of having a major positive impact on the revenue that they earn from the sales. This is a great step towards fighting piracy and giving gamers the experience that they deserve.

Fun Educational Games to Play in the Classroom

Students that are engaged in learning are more likely to enjoy learning and will, in turn, be more open to retaining your lesson. Fun educational games can assist in the fun. By using everyday objects to create curiosity, students and teachers can both increase the joy of the learning environment. Even adults prefer novelty. Think about the last time you had to sit in a lecture. Most adults get up, text, or talk during these types of presentations. Students are expected to not do any of those things and tend to tune out instead. Teachers should remain aware of those tendencies and keep it fresh and exciting. Fun educational games can be incorporated in math, spelling, and writing in your classroom.

Math lends itself easily to educational games. Many teachers continually complain about students not knowing rote math facts. The first five minutes of math class is perfect time to practice math concepts. Find a small football, koosh ball, or stuffed animal that can easily be held and passed from student to student. Set a timer for three minutes (more or less depending on your class), along with an expected amount of answers to get in that time limit as a class. Next, write a “magic number” on the board. Students will be giving the teacher different facts that will correspond to the “magic number” that are not replicas of what has already been given. The teacher starts the timer, gives the first student the answer item, and waits for a fact that would result in the “magic number.” The teacher writes the fact on the board, and the student passes the answer item to another student of their choosing and repeats the process. Answers that are repeats do not count. The goal is for the class to reach the predetermined amount of answers before the timer runs out. Teamwork is evident in this game!

Memorizing spelling lists can be torture for some students, but this fun educational game could be just the ticket to help. Place students in groups of six to eight. Each group pulls a chair up into a circle facing on another. The teacher chooses one student from each group to be the starting speller. The teacher then calls out a spelling word from the weekly list. The first student says the first letter, and then the group spells out the word around the circle, each student stating the next letter. If a letter is incorrect, the word must start over with the next student in the circle. Once the word has been spelled out correctly, the team puts their hands up to either side of them (side high fives) to form a circle and to indicate to the teacher that they have finished. The teacher waits until she sees a visual of all groups with high fives up before moving on to the next word. Groups will begin completing to finish first and fun with spelling will be evident!

Fun items get students thinking in this fun writing activity. The teacher will need to find several (3-5) interesting everyday objects and place them in a fun gift bag. The presentation is part of the fun. At the beginning of writing class, the teacher will pull out each item from the bag and show each to the class. If time allows, pass the items around. The teacher should not say names of the items as that might stifle the creativity of the students. After the class has seen and/or toughed the items from the bag, they are given seven minutes to “free write.” Students must use each of the items in their creative writing story, while still following writing format. Conventions, such as spelling, are not as important in this activity. By finding unusual items, such as plungers, potato mashers, or rare coins, students will expand their background knowledge and increase their creative thinking skills. After finishing, encourage a few students to share their work. There are sure to be lots of giggles with this educational game in your classroom!

Fun learning games are so important to incorporate in your classroom as much as possible. Review or filler times are a perfect opportunity to try out some of these ideas. When the learning is fun, your students will love coming to see you each and every day. Have fun!

MoS2 Low Friction Coatings – Not Just For The Aviation Industry Anymore

MoS2 low friction coatings (also known as molybdenum disulfide, also spelled, disulphide) are regarded the most widely used form of solid film lubrication today. What makes them unique (with the other dichalcogenides) is the weak atomic interaction (Van der Waals) of the sulfide anions, while covalent bonds within molybdenum are strong.Thus, lubrication relies on slippage along the sulfur atoms. All the properties of the lamella structure are intrinsic. No external form of moisture is required. In fact, best performance from MoS2 low friction coatings is attained in the absence of water vapor, which are prone to surface adsorption. This makes them ideal under vacuum.There are a number of methods to apply MoS2 low friction coatings, including a simple rubbing or burnishing, air-spraying resin-bonded or inorganically bonded coatings, and more recently by sputtering through physical vapor deposition (PVD).Thickness will vary, depending on form of MoS2 low friction coatings, but typically ranges between 5 to 15 micrometer. Sputtering techniques can produce thin films of 0.2 micrometer. While plasma sprays will result in higher builds, beginning at 0.003 inch or more.Friction coefficient less than 0.05 is attainable, but will also vary with humidity and sliding conditions. Tests show friction decreases with increasing vacuum strength. Friction also lowers with higher load, faster surface speed, or both. In fact, MoS2 low friction coatings are superior to both graphite and tungsten disulfide (WS2). Friction with MoS2 low friction coatings is independent of particle size, though the larger particles can carry more load.Dry lubrication for MoS2 low friction coatings remains superior at higher temperatures, with oxidation rates remaining relatively low at temperatures up to 600 degrees Fahrenheit. And in dry, oxygen-free atmospheres, lubricating performance, even with oxidation products, is stable to 1300 degrees Fahrenheit.Higher air flow can affect oxidation kinetic rates in atmosphere. Molybdenum oxide products (MoO3) and sulfur dioxide. Since MoO3 alone offers dry lubrication, based on its relative softness, molybdenum disulfide coating are ideal in higher temperature environments. At higher temperatures, though, they are better suited under vacuum. In atmosphere, they are prone to water adsorption from air based on their hygroscopic properties.As with the other dry film lubricants, while differences may prove negligible, you will have to determine which is better for you: longer wear life or better performance, using MoS2 low friction coatings. Generally, friction will be slightly higher by coating both surfaces, rather than coating one surface only. But wear life will increase coating both surfaces.Friction can be good in so many areas of life. Without it we could not easily stop and start our motion, or change direction. But in moving machinery, friction causes considerable loss of energy, poorer performance, not to mention limiting wear life.As with many non-lubricated systems, the static coefficient of friction is higher than the dynamic coefficient of friction. The resultant motion is often referred to as ‘stick-slip’. Basically, the two surfaces stick together until the elastic energy within the system has accumulated to some threshold, where a sudden, forward slip takes place. Under magnification, it’s apparent the union of two surfaces is often limited to intimate contact only at the tips of a few of the asperities (small scale, surface irregularities). At these point areas, pressures relating to contact may be near the hardness of the softer material. Thus, plastic deformation occurs on some localized scale. This is known as cold welding. Where bonded junctions are formed between two materials.For lubrication to occur, these bonds, this adhesive component of friction, must be broken. And this is where products like MoS2 low friction coatings serve well.So, where are these products used today? Consider aerospace, automotive, marine and electronic, for starters. There, you’ll find MoS2 low friction coatings, again and again.
