Label:Last week, there were clients. HCC compression: In order to reduce the storage to the database bandwidth consumption, so that the storage of HCC compressed all data transferred to the node is decompressed, and when the use of HCC compression, Exadata Intelligent scanning is not available, all the data need to be processed in the data node, Consume all the C
How to let the site be Baidu faster record, first of all, your site is hanging up? Of course, there should be no food so the webmaster and webmaster enthusiasts. HCC has always believed that the Web spider is very human, but also need to pay feelings to seduce spiders to read your website data. Therefore, to the site to be included in Baidu can try to start from the following aspects, of course, there is no guarantee that your site will be included.

The following is a simple example.If a project has three header files and eight C files, we should make the makefile look like the following in order to complete the three rules described above.

Countdownlatch is capable of waking up multiple waiting threads.The thread that reaches its expected state calls the Countdownlatch countdown method, and the waiting thread calls the Countdownlatch await method. If the count value of Countdownlatch initialization is 1, then this is degraded to a single event, that is, a thread notifies other threads, and the effect is equal to the object's wait and Notifyall,count values greater than 1 are common ways The goal is to have multiple threads reach
The interview encountered such a problem: threads A and thread B, how to control thread B in line a start 3 seconds or after thread a runs to start?The topic shows that thread B's start-up time is to meet two conditions:1. After thread a starts 3 seconds2. After the end of thread a runsThis means that as long as the above two conditions have a satisfying, thread B will start.Use Countdownlatch to control call timing, the code is as follows:1 Public classRunAImplementsRunnable {2 PrivateCoun

Control the startup sequence of two threads.
In the interview, I encountered the following question: How can I control thread B to start after thread A starts for 3 seconds or after thread A finishes running?
The question shows that thread B's start time must meet two conditions:
1. 3 seconds after thread A starts
2. After thread A finishes running
That is to say, as long as one of the above two conditions is met, thread B will start.
Use CountDownLatch to control the call sequence. The Code is
understand them very quickly.2. Dimension (Dimension)A dimension corresponds to an argument in a function, or an axis in a function image, which is an n-dimensional vector in linear algebra.(This is also the origin of the name of the dimension). In netCDF, a dimension has a name and range (or length,is a mathematically defined domain, which can be a discrete set of points or a continuous interval. In netCDF, the length of the dimension is basically limited,There can be at most one dimension wit

Dealing with this deadlock problem, spent several days, I believe that the classmate met, same headache, but there is a good helper class words (fortunately. NET API is strong enough), there is no such a headache attention
The solution for this article is only for use with lock (obj) or: Monitor.Enter (obj); .... The way Monitor.Exit (obj)A deadlock similar to purple
If you are using: Autoresetevent.set/rest, Monitor.wait/pulse, Mutex way, please find another method. Auxiliary class

makefile:
Objects = Main. o kbd. O command. O display. O/Insert. O search. O files. O utils. o
Therefore, we can easily use this variable in the "$ (objects)" method in our makefile, so our improved makefile will look like the following:
Objects = Main. o kbd. O command. O display. O/Insert. O search. O files. O utils. o
Edit: $ (objects)CC-O edit $ (objects)Main. O: Main. c defs. hCC-C main. cKBD. O: KBD. c defs. H command.
