Registering in Windows10 regsvr32 xxx.ocx reported an error but the call to DIIRegisterServer failed with error code 0x80040200…

There is a machine to read the resident id card on the website. It needs to install some registered activeX controls
and then enter the specified directory to execute the following command
regsvr32 XXX. Ocx
reported an error:
but the call to DIIRegisterServer failed with error code 0x80040200

 
Baidu once, found the reason is very simple, need to use the administrator identity to run
Type CMD from the control panel and right click Run as Administrator

This time it worked

Modify the screen resolution after installing Ubuntu 16.04 (xrandr: Failed to get size of gamma for output default)

Ubuntu 16.04 has only one option after installation, 1024×768. Using the xrandr command has an error:

xrandr: Failed to get size of gamma for output default

You can’t set it using the CVT command, nor can you modify xorg.conf.
Solutions:

打开：/etc/default/grub
搜索：#GRUB_GFXMODE=640x480
编辑：640x480 改成你想要的分辨率，并取消前面的#
例如：GRUB_GFXMODE=1920x1080 
更新：sudo update-grub
重启: reboot

If the above method has not been solved, then there is another situation is the video card driver has not been installed, the need to reinstall the video card driver can solve the above problem.

Apache server startup prompt HTTPD: apr_sockaddr_info_get() failed for
After configuring Apache on RedHat Linux 5 and CentOS 5 servers, always report an error when starting or closing:
HTTPD: apr_sockaddr_info_get() failed for XX (host name)
HTTPD: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName
does not affect the normal start of apache though say! But it always felt like there was something wrong. Because an Apache startup process is stuck in the process
Found under the data, the original is the host name setting is not caused! Not in the/etc/HTTPD/conf/HTTPD. Set the ServerName conf so it will use the name of the host to replace, will first go to have a host defined in/etc/hosts.
. To solve this problem, set ServerName or enter your host name MYHOST in /etc/hosts, like this:
> Vi /etc/hosts
127.0.0.1 localhost.localdomain localhost XX (host name)
The command to view the hostname is: hostName
 
Additional errors that may occur:
Stopping HTTPD: [root@bogon xy]# service HTTPD restart

Remove the # before ServerName from httpd.conf.

Browser prompt: Source mapping error: request failed with status 404 Source URL: http://xxx.js Source mapping URL: jquery.min.map

Browser Jquery1.9.1 min.js newspaper script error no jquery.min.map file
 
I recently encountered this problem when Browsing personal websites
Let me first say what a Source map file is.
Source map file is after js file is compressed, the variable name of the file replaces the corresponding, variable location and other metadata data file, generally this file and min.js main file are placed in the same directory.
Such as the original variable is the map after compression, compressed by variable substitution rules may be replaced with a, then the source map file will keep a record of the mapping information, so that the benefits of that is to say, at the time of debugging, if there is some JS error, then the browser will by parsing the map file to merge compressed JS, the developers can use the code to debug, uncompressed, this will bring us a lot of convenience!
Solutions:
Remove the sentence “// @sourcemappingURL =jquery.min.map”

 
 

springboot : Failed to decode downloaded font 和 OTS parsing error

Hello, I’m Roast Duck:
I have seen many people who have similar problems with me, but they have not solved my problems:

Failed to decode the listed font and OTS Parsing Error:
Trying to move the wOFF file to another static resource folder that can be loaded, it still cannot be loaded.
The browser opens access directly to the login page. The guess is that the static resource for the font is blocked.
 
Please refer to this:

Error details
Manifest merger failed : Attribute application @ appComponentFactory value = (. Android support. The v4. App. CoreComponentFactory) from [com. Android. Support: support – compat: 28.0.0] AndroidManifest. XML: make haste – 91
is also present at [androidx. Core: the core: 1.0.0] AndroidManifest. XML: value = “- 86 (androidx. Core. App. CoreComponentFactory).
the Suggestion: Add ‘tools: replace = “android: appComponentFactory” element to the at AndroidManifest. XML: 5:5 – the sons to override.

Solution 1: Add useAndroidX and enableJetifier as shown in the figure

android.useAndroidX=true
android.enableJetifier=true

Note:
this method does not need to add the classpath ‘com. Jakewharton: butterknife – gradle – plugin: 10.0.0’
but will import android. Support. V7. App. AppCompatActivity modified into import androidx. Appcompat. App. AppCompatActivity
is also all references Androidx package

Solution 2: Use the lower version of the package directly, as shown in the figure
Delete the build.Gradle plug-in at the top of the module, either one of the two below

apply plugin: ‘com.neenbedankt.android-apt’
apply plugin: ‘android-apt

The dependency in build.gradle under module is changed to :(only these two are needed)
// butterknife component injection

implementation'com.jakewharton:butterknife:8.6.0'
annotationProcessor'com.jakewharton:butterknife-compiler:8.6.0'

Note: the use of android package or the original
import android. Support. V7. App. AppCompatActivity

Mac reports an error zsh: fork failed: resource temporarily unavailable (reasons and solutions)

Mac report ZSH: fork failed: Resource Permanently (reason and solution)
MacOS version: 10.15.3 (19D76)
why
A few days ago, I used django-crontab to do the timing task and forgot to delete the task, which led to the continuous creation of processes in the background, and finally the terminal kept reporting errors, and the new browser and files could not be opened.
Check the following command to see that there are 1000+ processes in the background

 ps -ef | grep cron | wc -l

The solution
During this period, try to close crontab directly, but cannot close it all the time

sudo /usr/sbin/cron stop # 关闭命令
cron: cron already running, pid: 177

Final solution
First of all, empty the crontab task, delete what was created by what, for example, I passed django-crontab
So the command to remove the task is python manager.py crontab remove
Then batch delete the cron process

ps -ef | grep /usr/sbin/cron |grep -v grep | cut -c 9-15 | xargs sudo kill -9

Solve it!!
conclusion
The Mac exception occurs because the thread or open file exceeds the system limit. If such an exception is reported as an error and is frequent, and the restart does not work, you need to consider whether there is some program frantically starting the process in the background. Don’t go to modify the Mac thread/file limit, to find the root cause, if indeed because development demand process, then can consider to modify the Mac itself limits, otherwise just solve the abnormal surface, but the process is still on your background, constantly eat your system resources.

Quickly solve the problem of Vmware virtual machine “\\.\Global\vmx86”: the system cannot find the specified file

If your VMware virtual machine prompts this error:”

Unable to open kernel device "\\.\Global\vmx86": 系统找不到指定的文件. Did you reboot after installing VMware Workstation?
Failed to initialize monitor device.

”
Try this:
1. Shut down the virtual machine, download the green cracked version of Vmware and get the Vmware installation package
2. Unzip a folder, search for “vmx86.sys” in this folder, and copy
3. Enter this path: C:\Windows\System32\drivers, and search “vmx86.sys”. If this file exists, replace it (note that the backup is replaced)
4. Enter “Run” in the start menu: NET Start VMx86 and press OK;
5. Start the virtual machine and everything goes back to normal.

Note: This method is feasible for personal testing. Please refer to the network for some steps.
