crypto erase

We know that the security problems are becoming more and more serious, and there are many information leakage problems in some places. For example, a swap partition. The swap partition frees up some of the space in the hard disk space when the system's physical memory is not available for use by the currently running program. The freed space may come from programs that have not been manipulated for a long time, and the freed space is temporarily saved to the swap partition until those programs a

Original: HTML5 Erase effect for eraser　　Disclaimer: This article is original article, if need reprint, please indicate source waxes, thank you!　　Recently the project just used this effect, that is, a bit like a scratch card, on the mobile device, a picture is scraped off to show another picture. As follows:Demo Please poke right:demo 　This is quite common on the Internet, originally wanted to directly online to find a demo to apply his method on the

, so the system will be caught in the repeated error correction, but can not repair the dead loop, eventually causing the system to think that the block address is damaged (bad block), but The SSD itself does not remap the physical block address corresponding to these logical block addresses (LBA), so this failure occurs, but the actual storage unit is not corrupted.Some of the new SSD users, encountered the above situation, generally think that the SSD has been a problem, must be repaired throu

Based on the HTML5 canvas technology to achieve the erase, scraping card effect, gently scraping the layer can simulate the real effect.Principle: Draw a gray mask on the canvas element with canvas canvas and other APIs, and then draw a transparent graphic by listening to the user's mouse move or gesture, so that you can see the real picture (or background image) in the canvas background, which is the erase

In practice, the string series in c ++ -- initialization, deletion, and Case sensitivity of string (construct erase upper-lower) The string has an iterator design pattern, and I have not yet realized the benefits brought by the iterator. Many times I can use methods similar to array indexes to complete the task. Scenario 1: Delete all uppercase letters of a stringHere the erase method is used: #include

Template methodGenerate instances of specific classes in a more streamlined way. The difference with the factory method is that the template class (abstract class) is used to control the process of the entire instantiation (a bit like the factory management class, the template method to control the overall process, and the concrete creation process is implemented by its subc

Perform a "Health Check" on the machine and find that the Bad Sectors in Zone E are 8192 bytes. Run the Win98 disk scan immediately.Program, Cannot be repaired, or run the NDD disk Repair Tool. I remember seeing how the High-level hard drive repairs the logical bad track.ArticleFormat the file first.Immediately go to the advanced formatting Area E under DOS, and then enter Win98. As a result, I almost collapsed on the Chair: The bad sectors were not eliminated, but increased by more than 3 m. Ho

If all DIY do not want to, manually empty the _common_block, _common_diy_data and _common_template_block table, and then delete all sub-folders under \data\diy\, to ensure that all your previous DIY clean , just like Disciz X, which has never been DIY.After the removal of DIY content, honestly first delete the module, and then delete the frame, do not dream of directly delete the frame will be connected to the module to help you delete, as for the front desk diy "empty" really can empty, and foo
