If you have just entered the world of professional software development, you have a certain knowledge, thanks to education and/or training in computer science and programming. But the real business of development is different from school programming, which is something you can't learn from college courses or coding schools.Whether you are a graduate who has just graduated from your first development job, or an older person with a certain amount of experience in programming, the following is a su

To write time in standard format to log files. To convert time (now () to character format "YYYY-MM-DD hh: mm: SS Zzz" Write this function, Delphi system itself also with the Conversion Function formatdatetime ('yyyy-MM-DD hh: mm: SS zzz', now ()) You can also implement this function. Considering that this is a fixed-format conversion function for further optimization. // Actual test results Run 1,000,000 formatdatetime () ==> 2825 Ms Sfformatdattime () ==> 545 Ms // YYYY-MM-DD hh: mm: SS zzzP

, which can lead to a lot of repetitive work. For example, we want to modify the static page CSS based on the class and ID generated by Drupal. Although we can use the theme function and template to rewrite most of the structure of Drupal to achieve the same as static pages, but this is a lot of work, and many projects, do not care about the structure of HTML. Of course, if the project budget is sufficient, then such a overwrite is also to be done, the general project, we still recommend first f

One of the biggest advantages of using ADODB is that, regardless of the backend database, the methods for accessing the database are the same, so developers do not have, however, you must learn another set of different access methods, which greatly reduces the knowledge burden on developers. the previous knowledge can still be used in the future. when the database platform is transfer

Then thread 1 reads the latest correct value. 2.volatile guaranteed atomicity. Knowing the volatile keyword above guarantees the visibility of the operation, but volatile guarantees that the operation of the variable is atomic. Let's look at an example: public

layer, is the CPU L1 or L2 cache of the corresponding cache line invalid); Third: Because the cached row of the cached variable stop in thread 1 's working memory is invalid, thread 1 reads the main memory again when the value of the variable stop is read. Then thread 2 modifies the stop value (there are 2 operations here, of course). Modifying the value in the thread 2 working memory and then writing the modified value to memory invalidates the cached row of the cached variable stop in the w

The answer is no guarantee.Let's look at an example:

access methods, which greatly reduces the knowledge burden on developers. the previous knowledge can still be used in the future. when the database platform is transferred, the program code does not have to be too much updated. In fact, the development concept of ADODB is not the first. DBI appeared earlier than ADODB. It provides Perl to access the database and uses consistent API call interfaces. I believe that friends who have used Perl + DBI will have a similar feeling when they use ADODB

One of the biggest advantages of using ADODB is that, regardless of the backend database, the methods for accessing the database are the same, so developers do not have, however, you must learn another set of different access methods, which greatly reduces the knowledge burden on developers.
