Let's think about the output of this program. Maybe some friends think it's 10000. But in fact, running it will find that the results are inconsistent each time, is a number less than 10000.

A single row contains a list of the shortest moving orders that point all pointers to separated by spaces.
If there are multiple solutions, output the one that makes it connect to the smallest number. (For example, 5 2 4 6

operational expenses related to power, cooling and maintenance.2. Hybrid RAID SolutionFrom a hardware perspective, building a hybrid RAID solution can use any capacity SSD and HDD (though the number of SSDs and HDDs must be the same). If the RAID array uses a different drive size, the drive capacity is the smaller one. For example, a RAID 1 With 1 128GB SSDs and 2TB HDDs, the logical device is 128GB. A RAID 10 uses 2 128GB SSDs and 2 2TB HDDs, and the logical device is 256GB. The remaining HDD

]);
This defines five columns, which can be configured by parameters: IDs are used to identify columns, which can be used in CSS to set styles for all cells in an entire column, and columns that can be automatically expanded are identified by this ID; the header is the column name; the width is the widths of the columns; Sortable is used to indicate whether the column can be sorted, dataindex, and ignor

Selection of SCSI devices1.SCSI CardSCSI cards are key to the entire SCSI device chain, and there are several factors to consider when choosing:(1) The brand of the SCSI cardChoosing a brand is important, Adaptec is a SCSI card boutique, like CPU Intel, is already the SCSI standard, of course, compatibility is no problem, and expensive price may be the only problem.

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
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
before writing the volatile variable).Thread A writes a volatile variable, and then thread B reads the volatile variable, which essentially is thread a sending a message to thread B through main memory.
Does 5.volatile guarantee atomic sex?
Knowing from above that the volatile keyword guarantees the visibility of the operation, but does volatile guarantee that the operation of the variable is atomic?

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
which the driver of PostgreSQL, Informix, and Sybase is contributed by the development of the Free Software Community ).
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

In addition, ADODB should be familiar to people who have used ASP. Such friends should be very easy to accept.
