Problem DescriptionIt is said that in a long long time ago, poor rabbit experienced the biggest blow in life-the race lost to the turtle, heart depressed, vowed to avenge, so hid in the Hangzhou Xiasha Agricultural Park hardships painstaking practice, and finally practiced into a stunt, can not rest at a constant speed (VR m/s) has been running. The rabbit has been trying to find a chance to teach the turtle a shame before the snow.Recently, HDU held
Comet on Adobe Max to show you from Google spreadsheet, from the Web page and other sources directly to the data into the design manuscript, impressive. This is a clear trend that most applications should support this year.
Real data, whether for design decisions or product decisions, will have a very direct effect. (already have too many products to see the effect of the picture self feeling super good, real one on line dad don't know)

Smart objects
Fortunately, there have been many articles about the power of the Internet of things. Intelligent objects will interact with humans and their surroundings using technologies such as AI and machine learning. The most typical examples are driverless cars, drones, smart kitchens and smart homes that are also emerging. Gartner predicts that these smart objects will become increasingly interconnected and continue to improve our standard of living.

Security enterprise Crowdstrike wrote in its malware sample analysis article. "Looking at the missing part of the code, we will find that this is not a well-laid targeted attack behavior ."
Crowdstrike's security researchers explained that from the Trojan attack behavior, it seems that malicious software

The third-party control has two controls: UICommandManager and UIPanelManager, which are helpful for plug-in insertion and display.
When this host is instantiated, an Apllication class is first instantiated, and then an important attribute value is assigned to MapControl, PageControl, and MainPlantform in this instance.
Therefore, the interaction between the host and the plug-in is not di

According to the latest news from the foreign media, Microsoft HoloLens, an inventor recently said that the smartphone has died, the future will
In distributed system, redundant data is the means of guaranteeing reliability, so the consistency maintenance of redundant data is very important. In general, a write operation must update all redundant data to be called a successful end. For example, a data on 5 devices have redundancy, because do not know the reading data will fall on which device, then a write operation, must be 5 devices are updated to complete, write operations to return.For systems with frequent write operations, the bott
