there is no strange equipment, if someone rub the net to decisively kicked off, if you are outside, and no one at home, then simply put "wireless switch" set to close. What does "Panel light switch" do? If the pole route is in the bedroom, and the evening panels are flashing, you can just take out your phone and turn off the panel light. It's not an advanced feature, but it's really practical and intimate. Simple upgrade Normal routing can also upgrade firmware, but usually to the official w

Analysis: high concurrency, large data write data, will write the data into memory, accumulate a certain amount, and then in a timed or quantitative write to disk (reduce the disk IO (input/output)), eventually will load the data into memory and provide external access . Characteristics: Advantages: Write data to memory, high performance, fast speed (Weibo, SNS, Seconds Kill product) Cons: You may lose a piece of data in memory that has not yet been saved to disk ways to resolve data wit

weights. Only in this way can we surpass our competitors. Because you are after all, others themselves in other areas have accumulated a lot of weight. To go beyond, of course, you can do more. I have thought of such a way before, we can refer to. But not recommended, it is best to use the way I said above. My approach is this, if my site has three core keywords, in order to assign the site link to the extreme. Then I will have a keyword first to do
