vizio issues

In development, sometimes we need to do some network-related testing on our computers, so we have to simulate the network environment locally.In a simulated network environment, you will often encounter problems with access rights. Now I'm going to write my own solution. I use the simulation server site is sites, about this, you can go to see my another article.First go to the folder,See if you have the following files, which are not created, and you can use the Touch username.config command at

Today in Ubuntu work suddenly appeared on the screen up and down a roughly 2 centimeters of black bar, feeling the screen was stretched horizontally, inexplicably, began to think that the simple adjustment of the resolution is good, in the system settings display found only two optional parameters, and the object is unknown, because previously did not notice here, Not aware of anything unusual.

restart MyEclipse with new Virtul machine memory paramters to increase this m Emory. Failure to does so can result in data loss.The recommended Eclipse memory parameters is:eclipse.exe–vmargs-xms128m-xmx512m-xx:permsize=64m-xx:maxpermsize=128mThe following commands are available to resolve this issue:The command is: eclipse.exe-vmargs-xms256m-xmx700m-xx:permsize=150m-xx:maxpermsize=300mAssuming my eclipse is under E:\eclipse-SDK-3.2.1-win32\eclipse, the command I need is:CD E:\eclipse-SDK-3.2.1

memory of the system-xx:permsize: Minimum heap size. Generally reported that the memory is not enough, it is said that this is too small,The remainder of the heap space is less than 5% warning, it is recommended to set this slightlyLarger, but depending on the size of your machine's memory to set-xx:maxpermsize: Maximum heap size. This one's a little bigger.-xmx512m 5% is 25.6M, theoretically requires-XMX value and-xx:maxpermsize must be greater than 25.6MChange the parameters inside to-vmargs-

The first problem encountered is not: Error-mpdf requires mb_string functions. Ensure. PHP is compiled with Php_mbstring.dll enabled.There is no problem in the Windows environment, and it is encountered under deployment to Linux. The solution is to execute the command yum install php-mbstring.x86_64You can view StackOverflow's problem, address connection http://stackoverflow.com/questions/12708855/ Ensure-that-php-is-compiled-with-php-mbstring-dll-enabledMpdf

1. VirtualBox There is no 64-bit system option problem: Use the securable tool to detect if the computer supports virtualization, if it is supported to restart the computer to enter the BIOS to see if virtualization is turned on2. After installing Ubuntu, the native ping does not pass the virtual machine: Check the setting item network connection mode whether the bridge connection is selected, the NIC is consistent with the network card connected to your native computer.3, ping virtual machine X

and enter. 2. Networking issuesIn fact the setup is very simple, must correspond clearly.In the case of a wired host connection, the virtual machine settings use NAT mode, share the IP address with the host, then enable VMNET8 for the host's adapter, and set the advanced settings of their local connection for Internet access to shared mode.Restarting the virtual machine can be done. After the completion of these two work will be the system to update the relevant patches, installation of inp
