Does Memory Optimizers and RAM Boosters really useful?


Many companies want to sell you “memory optimizers,” often as part of “PC optimization” programs. These programs are worse than useless — not only will they not speed up your computer, they’ll slow it down.
Such programs take advantage of inexperienced users, making false promises about boosting performance. In reality, your computer knows how to manage RAM on its own. It will use RAM to increase your computer’s performance — there’s no point in having RAM sit empty.

Is Your Computer’s RAM Filling Up? That’s Good!

Memory optimizers are based on a misunderstanding. You may look at your computer’s RAM and see it filling up — for example, you may have 4 GB of RAM and see that 3 GB is full with only 1 GB to spare. That can be surprising to some people — look how bloated modern versions of Windows are! How are you ever going to run additional programs with so little memory available?
In reality, modern operating systems are pretty good at managing memory on their own. That 3 GB of used RAM doesn’t necessarily indicate waste. Instead, your computer uses your RAM to cache data for faster access. Whether it’s copies of web pages you had open in your browser, applications you previously opened, or any other type of data you might need again soon, your computer hangs onto it in its RAM. When you need the data again, your computer doesn’t have to hit your hard drive — it can just load the files from RAM.

The truth behind jailbreak tool - How can Evasi0n make a FREE jailbreak tool for iOS?

Each year, fans and hackers always waiting eaglerly the iOS jailbreak event (it's a major event). This year, people still waiting the jailbreak for iOS, but something has changes: jailbreaks becomes big business.
jailbreak IOS TaiG marketing

For example, Evasi0n's hacker team jailbreak both iOS 6 and iOS 7. After jailbreak iOS 7, iPhone users with Chinese language found that a program automatically installed named "TaiG". TaiG is an App Market which offered Chinese-language apps, and the important is thousand iOS app "cracked" (pirated, no license required).

The group made "around a million dollars" in placement fees for adding TaiG to Chinese iPhones. While the actual number is currently unknown, my source explained that the rumors were true and that the fee was well within that “order of magnitude.”
The Evasi0n team, for their part, responded online to allegations that they had been paid to put pirated app stores on users’ phones:
"Yes, we have benefitted financially from our work, just as many others in the jailbreak community have, including tweak developers, repo owners, etc. Any jailbreak from us will always be free to the users but we believe we have a right to be compensated in an ethical way, just as any other developer. However, the interests of the community will always be the most important thing to us. When releasing the jailbreak, we pledged all our donations to foundations supporting the interests of the community. We are deeply upset at how we have inadvertently distressed the community and we are focused on fixing it.".

Evasi0n also said that TaiG have many pirated app: "We are very upset that despite our agreement and review by their team, piracy was found in the store. It was not acceptable and they have been strenuously working to resolve the problem in good faith, and have removed all instances of it that we have brought to their attention".

Jay Freeman, a developer with nick name "saurik"creator of Cydia, said: "The jailbreak works and people should use it". Cydia is a popular “feature store” that allows users to shop for tweaks and updates to their iPhone’s OS.
"The thing that bugs me [about TaiG] is there’s tons of piracy in it. We’re not about piracy. It used to be that if you wanted to pirate you did have to jailbreak. That’s no longer the case. But people still look at us we’re those pirate assholes", said Freeman.

Jailbreaking is a business now. Saurik himself makes a living off of having his app installed on jailbroken phones and the Evasi0n team, among others, make money selling space in their apps. In short, things have come a long way since the lone hacker spent time cracking iOS in his spare time.

What does the TaiG partnership mean? Very little, in the long run. Even George Hotz (nick name Geohot), a well-known early iPhone jail breaker, attempted to sell his own jailbreak technique to unidentified buyers for $350,000 to a commercial customer.
In the end, Evasi0n released theirs for free, heading potential for-pay jail breakers off at the pass. That they made money for adding TaiG, in fact, should be immaterial.

Everyone want their work paid. Freeman also said that "Evasi0n do good work and I think they deserve money for it". That the TaiG app store contains pirated material, however, is another matter entirely. Now that jailbreaking is a business, people want to get paid, but not this way.
