Perhaps Emacs Big God are not bothered to write articles, feel the online Chinese emacs data is small but not whole, there are a lot of outdated. Since I've benefited a lot from Emacs, from writing code to data sorting to drawing to writing paper to the final big paper ... So I want to write an Emacs series of articles, on the one hand for the promotion of Emacs blocks, on the other hand is also a catalyst, I hope to learn a lot of exchanges. The series of articles probably includes the followin

error. A common workaround is to use a case statement to determine if the denominator (denominator) is 0, and then divide the operation. Select Case-num_users = 0 Then 0 else total_sales/num_users end; The way ASE statements are actually very difficult to see, and the denominator is reused. If this is a simple situation, if the denominator is a complex expression, then the tragedy comes: it's hard to read, it's hard to maintain and modify, and it's a bunch of bugs. At this point we can look a

shortcut key C-a] to paste the contents stored in buffer into the current window.6.6 More screen FeaturesLike most Unix programs, GNU screen provides rich and powerful customization capabilities. You can specify more in the default level two profile of screen/ETC/SCREENRC and $HOME/.SCREENRC, such as setting screen options, customizing the binding key, setting the screens session self-launch window, enabling multiuser mode, customizing user access control, and more. You can also specify the scr

example, I can do this:[email protected] ~]# CP file1 File2 In this sequence of commands, focusing on that function, he said to copy file1 this file as File2, and put it in the background to run, that is, after running this command, in this one terminal interface can still do other work! And when this command (CP file1 File2) is finished, the system will display the completed message in your terminal interface! Very convenient! The system resource allocation problem of multi-person an

Set represents an unordered set, the set element is not repeatable; Map represents a collection of multiple key-value pairsFrom the inheritance system diagram of set and map, if the name analysis, set and map are inextricably linked. And from the map interface provided in the JDK, you will find that a method is provided: SetImport Java.util.hashset;import Java.util.iterator;import Java.util.map;public class Simpleentry Java Collection Research one: se

have to take a [comfort zone], learn in [learning area], and overcome fear. Second, you have to make small goals for yourself, such as practicing some code every day, and sticking to it, and at the same time, focusing on your weaknesses and practicing, solving those low-level problems, turning them into automatic actions without having to go through the brain, and then having time and brainpower to solve higher-order problems. . And in the course of practice to focus attention, so long-term per

There are a lot of friends in the group asked me PPT has a lot of pictures how to better to show it? I personally think there are a lot of methods, but also to clarify your PPT to apply the occasion, so today to borrow a Yi Tian of "PPT picture switching effect Research" a text to explain the new idea of PPT picture switching. Now go to the point of understanding the iphone's friends know that the image of their browsing switch effect is very good, d

The Logic:iterator label (hereinafter referred to as "the label") is a very common label in struts, which is used to loop through the values in a given container object So commonly used tags, the source code of course need to take out the study, the following list of several research results: 1, the label internal use collection to represent the given container, all the given container objects (such as ARRAYLIST,MAP, etc.) will be converted into col

follow the line of sight flow is roughly two kinds, The Gutenberg chart is a design idea for line balancing from the Gutenberg Chart of John Gutenberg. He suggested that when people browse the page or layout, the line of sight tends to move from top to bottom, from left to right eye movement. The upper-left corner is the beginning and the lower-right corner is closed. So the headlines of the newspaper, the title of the magazine, the logo of the website and so on are all important information

In the previous essay As we all know, the list in the. NET Collection class is a sequential one-dimensional array, and unlike array, we can more easily manipulate the list type collection, such as inserting data, deleting data, sorting, and so on. NET source list is how to achieve it? Do we have other costs when we use the advantages of list versus array? What can we learn from the list source? With these questions, let's start today.
