capacity to support a larger pool of threads. The premise of an accurate assessment is that we have to assess which resources will limit the application's ability to scale. In this article, we will assume that the CPU is, and in practice, other resources. The simplest case is that we have enough space to increase the size of the thread pool. If not, you have to consider other options, such as software tuning, adding hardware, or tuning and adding har

attackers has decreased, the damage to each attack is increasing (the number of servers hijacked is only high). Now we have to study carefully, in the end is the lack of skills or safety awareness? Why does the database system continue to run in an older version? Or is there a latent loophole that has not yet been discovered by us? Gevers also said he had to introduce a group of external experts to assist in the analysis of MongoDB issues. The GDI Foundation has a lot of work to do and i

Here, do not put the cart before the horse, some in the direction of business has not been clear, the blind construction of large-scale Internet architecture, is rich + burn money. There are also small startups that blindly mimic Facebook, BAT, for technology and technology. In addition, the de

problem of SQL too long error (default 1M)Scenario Three: Directly query a large time period of data, not statistics, directly back in the library data, in the code (that is, in memory) to go back to the List, for each entity, traversing the time period, the entity to match to this time period, map (key,list), key is the segment number, The list saves the entities for that time period. The data is ultimately counted for each time period. The third scenario, which takes 1-2 seconds, proves again

The scale on the map indicates the degree to which the distance is smaller than the actual distance. The formula is used to indicate: scale = distance/Actual distance on the graph. There are three methods to express the scale. (1) Digital: The scale is displayed in the proportional or fractional Form of a number. For e

Scale generation: mainly related to water quality. If the water quality is hard, the oxygen content in the water is insufficient, and the water molecules are unstable, the solubility of calcium and magnesium ions in the water will decrease, and precipitation will increase, thus forming scale. As long as the water temperature exceeds 60 ℃, especially in the north where the water quality is hard, there will c

The discussion of sparse radicals has been going on for nearly one months, this time to discuss multiscale geometric analysis. However, as the following discussion of these transformations are mainly oriented to the image, and I am now mainly focused on one-dimensional signal processing, so it is not in-depth discussion of these transformations, here only in the conformity of the reference literature to collate some relevant content as their own memo, the concept may not necessarily understand t

(Dark good director ....) SOURCE one)Because the texture is formed by the repeated appearance of the gray scale distribution in the spatial position, there is a certain gray relation between two pixels separated by a distance in the image space, that is, the spatial correlation characteristic of the gray level in the image. Gray-scale co-occurrence matrix is a common method to describe textures by studying
