fir302b, saving bricks: This fir302b is really abnormal, like other bcm5357 is not so troublesome, but this device is cheap. It only costs 39 RMB for one device, which is very cheap. 1.

Today, when we were working with Sony to solve the bug, they found that they were testing TTL files. A curious afternoon to see what this is a scripting language, for many people, I am not very low ah, haha, this does not understand, but I do not understand, ^-^. with Curiosity, began to read the syntax of the scripting language, after reading actually and C language is no different. 1. Learned how to use the Commnd--connect '/c=3 '-----first open th

TTL index:The TTL collection enables MongoDB to set the expiration time for stored data, after a specified period of time, or at a specified point in time, the collection is automatically cleared by Mongod. This feature facilitates the storage of some data that only needs to be kept for a certain amount of time, such as event data generated by the machine, logs, session information, and so on.First create a

Tags: mongodb ttlThe TTL index (time-to-live index) allows you to set a time-out for each document, which is deleted when the document exceeds that time.You can create a TTL index by specifying the EXPIREAFTERSECS option in Ensureindex:>db.foo.ensureindex ({"lastupdated": 1},{"Expireaftersecs": 60*60*24})The above command creates a TTL index on the lastupdated fi

Introduction:One of the depressing reasons is that the CSDN blog suddenly fails to be opened, and it won't work if I look at it. I think it's unreasonable, It can be opened on a mobile phone or on another machine. Other websites are okay. It is too slow

1 reviewsMAX3483, MAX3485, MAX3486, MAX3488, MAX3490, and MAX3491 are 3.3V, low power transceivers for RS-485 and RS-422 Communications, with one driver and one receiver in each device. The MAX3483 and MAX3488 have a slew-limiting driver that reduces EMI and reduces reflections caused by inappropriate termination-matching cables for error-free data transfer up to 250kbps. The MAX3486 's drive slew rate is partially limited and can achieve a transfer rate of up to 2.5Mbps. The max3485,max3490 and

Modifying the TTL parameter value can prevent hackers from getting the correct information through the network, thereby improving the security of the system. Step 1: Open the Registry Editor window, and in the left pane, expand the hkey_local machinesystemcurrentcontrolsetservicestcpipparameters option. (Switch Input Method: Input method can not switch how to do?) Step 2: In the Drop-down list box on the right side of the window, select the Default

, restart the instance to take effect. You can also use the Client Command config set maxmemory to modify the value. This command takes effect immediately, but will expire after restart. You need to use the config rewrite command to refresh the configuration file. If the redis snapshot function is enabled, set "maxmemory" to 45% of the memory available for the system, because the snapshot requires twice the memory to copy the entire dataset, that is t
