How to count the frequency of each word in a 2 GB file? when a beginner encounters a problem, count the frequency of each word in a 2 GB file, after modifying the memory limit, the error "Allowed memory size of xxxx bytes exhausted" is still reported. The total number of lines or characters in the test can be output. how can this problem be optimized? ini_set("memory_limit", "-1");function calcWordFrequence

In the IP address- gt; in the evaluation of geographic location conversion, the article mentions that using the ip2addr function to directly read IP addresses is the most efficient to directly read IP database files using the ip2addr function in the evaluation of IP address-> geographic location conversion., compared to using a MySQL database to store IP data, SQL queries are the most efficient. However, the IP database file QQWry. dat is GB2312 encoded. Now I need the geographic location result

In the evaluation of IP address- gt; geographic position conversion, ip2addr function is the most efficient function to directly read IP database files. compared with MySQL database, SQL queries are the most efficient. However, the IP database file QQWry. dat is GB2312 encoded. Now I need the geographic status results of UTF-8 encoding. If MySQL is used, data can be converted The article "IP address-> geographic status conversion evaluation" mentions that using the ip2addr function to directly r

The computer on hand is still a second-hand machine bought in Kunming. It has been almost four years since, with M memory and 60 GB hard drive, when I first bought it, I had already fallen behind the times. Now, I am about to enter the ranks of antique machines. Finally, I thought about it and planned it. With the help of my colleagues, I moved my host back from the computer market. AMD dual-core, GB hard

According to foreign media reports, the Research Institute iSuppli recently said that Google's upcoming free network storage space may be as high as 50 GB. Google's network storage space will reach 50 GB At the end of November, it was reported that Google would launch the network storage service, allowing users to store files on Google servers on local computers. This service is free of charge, but u

. It is more concise and readable than multi-threaded code. This project was launched by EVE Online and is indeed strong in concurrency and performance. Similar to Python, you can consider replacing Python with the original system. :) Why MongoDB? Http://www.mongodb.org We can see many popular apps using MongoDB on the official website, such as sourceforge and github. What are the advantages of RDBMS? First, the advantage in speed and performance is the most obvious. It can be used not only as a

Create a boot disk for an image larger than 4 GB by using ultraiso, and use ultraiso4gb The ultraiso software is very convenient for boot disks. It is generally used for linux, windows, and Shenma. However, ubuntu generally only has 1-2 GB, windows desktop edition is usually about 3 GB, so you don't have to consider this issue. However, when you want to create

In 64-bit Linux, how does one run a 32-bit application? In the case of 32-bit programs, it is advantageous to use a 32-bit system and use RAMDISK to allocate unrecognized memory to the hard disk for virtual memory! Although the 64-bit system can recognize more than 3 GB memory, it cannot make 32-bit programs use more than 3 GB memory! With more than 3 GB of memor

When a CentOS 5.6 machine needs to upgrade the memory to 6 GB, the system is found to be 32-bit, so the search can enable the 32-bit system to support 4 GB memory or above. How does one enable 32-bit linux/Centos to support 8 GB memory? The kernel-based PAE installation supports a method larger than 4 GB memory. Linux/

Using the IP2ADDR function to read the IP database files directly is the most efficient, and SQL query is the most efficient one, compared with the MySQL database to store the IP data. However, the IP database file QQWry.dat is GB2312 encoded. Now I need UTF-8 coded geographic results. If you use the MySQL method, you can convert the data to the UTF-8 code when it is stored in the database. But QQWry.dat file can not be modified, only the output of the IP2ADDR function can be dynamically convert

For more information about how to enable 32-bit windows and linux systems to support 64 GB memory-Linux Enterprise applications-Linux server applications, see the following. From: http://blog.163.com/herod_xiao The relationship between the number of computer addresses and memory. The maximum memory supported by a 32-bit computer is 2 to the power of 32 to 4 GB, and the maximum memory supported by a 64-bi

How to enable the 32bitLinux host to support a large memory of more than 4 GB-Linux Enterprise Application-Linux server application information is described below. The times are different, and the memory is getting bigger and bigger. 4 GB memory is nothing for the server, but the maximum memory addressing space supported by the 32-bit system is 2 ^ 32 = 4 GB.

1. Two strategies for optimizing the Model:1) method based on residual errorResiduals are actually the difference between real and predicted values, in the process of learning, first learn a regression tree, and then the "real value-predictive value" to get the residuals, and then the residual as a learning target, learning the next tree, and so on, until the residual difference is less than a threshold of nearly 0 or the number of regression tree reached a threshold. The core idea is to reduce
