I'm Ronaldo, Newbie of Stackoverflow.
I'm having a problem, On my PC it's running Windows 10 Build 1803, Then I installed QEMU, but not only that, I installed the graphical version which is QtEmu.
Then I wanted to virtualize CentOS 3.1, with Disk 1, Disk 2 and Disk 3. But I don't know how to eject the disk in QtEmu, I tried it in PowerShell and I couldn't, not even in CMD, just the serial0, and the keyboard is not works, only on the PC that works. the Mouse is ok. But QEMU Monitor is out of QtEmu! Is there any way to install QEMU Monitor on Windows, with QtEmu?
Please help me!
QEMU can be started with option "-monitor" so you can send commands to it there. I never used QtEmu so not sure how it starts QEMU. If you figure out how, check out https://qemu.weilnetz.de/w64/2012/2012-08-24/qemu-doc.html#pcsys_005fmonitor.
So basically, you can use "change" command to mount and unmount a CD drive or other storage devices. For example, "change ide1-cd0 /tmp/file.iso" to mount an image file. The device names are not fixed across different VM configurations. "info block" can tell you what name you need to use.
sorry i just discovered QEMU, it's far now, but it can help people in the future.
I dislike QTEmu and others IHM, too much bugs currently (2022)..
With QEMU
default mode: you can directly have an access with the window, go to view and you can switch by clicking on "compat monitor 0" . You can also detach the monitor.
sdl: ctrl+alt 2.
Here:
Identify your devices by "info block"
As you can see here, i ran without anything (it's just to show).
To change/add content of your cd-rom, "Change "
here my device is "ide1-cd0"
Path can be your physical or virtual drive, a disk image, you can always swap according your needs.
As you can see now, i use "R:", a virtual device from a software like daemon tools (an alt).
I think it's better, before to swap, to eject from the guest... But perhaps
it depends of your OS. For the while i used it, the most of time, with win98x.
I am trying to install MySQL on a Windows 10 PC. I downloaded the installer package and followed those steps
Went to https://dev.mysql.com/downloads/windows/
clicked on "MySQL Installer"
Scrolled to Generally Available(GA) Releases section
Clicked on "Windows (x86, 32-bit), MSI Installer" (mysql-installer-community-5.7.21.0.msi) and it started the download.
Once the download was complete, I double clicked on the installer and it gave a usual pop-up for any installation like,"Do you want this app to make changes to your device?" after clicking on "yes" for the answer to this question, it shows "Please wait while Windows configures MySQL-Installer-community" like below screenshot.
And then it keeps showing this installation progress bar for a very long time. Like more than 7-8 hours and the installation never completes
So it seems something is wrong as I don't think MySQL installation needs this long time. I tried to restart my computer and then delete any files related to MySQL from my computer and then started the whole process of installation again. But no luck yet
Anyone has any suggestion on this or did anyone face this kind of issue before? If so, is there a fix or a work around for this?
ok. So finally this is how I resolved my issue. And I found the solution at https://bugs.mysql.com/bug.php?id=82004 . The solution to this problem is to close an open "Windows installer" (the one using 0 memory and CPU) via task manager and the installation should begin running as expected.
Alternative solution: Use an administrator command prompt to run the MySQL installer on Windows 10. Details:
(Note: if you have any problems in the following steps, you can try to restart your computer. Then restart the steps.)
Right-click the Start/Windows icon in the bottom-left corner of Windows.
Click: Windows PowerShell (Admin).
A window asks: Do you want to allow this app to make changes to your device? Click: Yes.
Change to the directory with the MySQL installer. For example, if you downloaded the MySQL installer, type something like:
cd C:\Users\my_username\Downloads\
(Note: To save some typing, you can type a few characters, and then press the tab key, to make Windows show you various auto-completion options.)
Run the MySQL installer. Type something like the following command---make sure to include the period and backslash at the beginning---and press Enter.
.\mysql-installer-community-8.0.11.0.msi
Note: The idea of using an administrator command prompt came from John Geffe, in the link below, which was cited in the answer written by the original poster (user8425592):

Bug #82004 MySQL Installer freezes during "Please wait while Windows configures..." phase

To get past this problem I had to run the .msi installer from an the
Administrator command prompt. Hopefully this helps someone in the
future.

John Geffe: Thanks! Your note on installing as an administrator seems
to have taken care of the problem.
this did the trick for me: https://ao.ms/mysql-community-server-msi-installer-hangs-on-windows-10/
run cmd (commandline) as Administrator
cd to your location that you downloaded the .MSI to
run the “msiexec” commandline tool with option “/i” as follows:
msiexec /i [replace with file name]
example: msiexec /i mysql-installer-community-5.7.20.0.msi
Another thing that worked for me was running the installer in compatibility mode for previous version of Windows. You can try that as well.
Go to the link you provided (the first one) and try installing MySql Workbench. That is the version that is commonly used, and one that I verified works in Windows 10. Here is the link: https://dev.mysql.com/downloads/workbench/
Obviously, make sure you choose the right architecture, have the correct permissions to install software, and have enough space on your hard drive, or on the machine you are installing to.
Please install "Update for Visual C++ 2013 and Visual C++ Redistributable Package" from Microsoft Site "http://download.microsoft.com/download/0/5/6/056DCDA9-D667-4E27-8001-8A0C6971D6B1/vcredist_x64.exe"
Please look here at https://support.microsoft.com/en-in/help/3179560/update-for-visual-c-2013-and-visual-c-redistributable-package
Yes, I also got the same problem on my Windows 10.
Followed the Powershell solution and it worked.
Just repeat the above:
Click Start on bottom left corner
Scroll down the application list until Windows Powershell
Select Windows Powershell again on sub-menu
Type in cd (to change to your .msi folder)
Type .\xxxxx.msi (this is the installer file name)
All good.
Once you install the above package run the installer again and do the steps. You will be able to install the mysql-installer-community-5.7.21.0 for 64 bit windows 10
closing Windows Installer instances using 0 memory and CPU helps me to get past this problem.
For me on Window-10 machine, there was a problem with the "mysql-connector-net-8.0.11.msi". I was not able to uninstall this and hence all my subsequent efforts to install MySQL were failing. I did the following to overcome this issue.
Re-installed "mysql-connector-net-8.0.11.msi" Get it here and used the 'Repair' option
Installed the "mysql-installer-web-community-8.0.11.0.msi"
These two things solved my problem. Hope this helps.
The reson is your antivirus didn't allow the mysql, so Disable protection(until restart),( in your task bar right side click the arrow and right click to antivirus,to select (Disable protection(until restart)).then restart your computer again install mysql installer it will work.
For this issue just run .msi file in command administration like
E:\mysql-installer-community-8.0.20.0.msi\
follow this link:
https://kb.foxitsoftware.com/hc/en-us/articles/360040660611-How-to-install-MSI-from-command-line-with-administrator
In my case, an upgrade to 5.7.29 on Windows 10 via mysql-installer-web-community-8.0.20.0.msi, the install froze "backing up the database". The log tab showed no activity for 8 minutes. I clicked on cancel, then at the "are you sure" prompt I declined to cancel, and all of a sudden the install was working again. Very strange...
I encountered the same problem, preparing but can never get started. Tried to close other installation programs with no use, but I took the inspiration and proceeded with restart the computer and it worked nicely. So, I think the issue is to get rid of everything that could be in the background running that somehow interferes the installation.
You should run the installer as an administrator but this specific installation may not provide an option for this. Some might have it but it's most likely that it's unavailable for many users. So you should run it in cmd or powershell. And don't forget to run these shells as an administrator coz that's the whole point here. Once there, navigate to the installer's location which usually is in the downloads directory and run it using this command ./name.msi
Make sure no other ongoing installation of this instance. Close it if there exists one and undo the changes made by uninstalling it from the panel. If still facing difficulties, try restarting your machine and repeat this procedure...
Have fun
I had the same Problem, A simple solution is to give access the "SYSTEM" to the msiserver...I know, this is hard to understand what I am saying....You can Simply see this Video and you will definitely find the answer https://www.youtube.com/watch?v=6SdXMjXmnUk, It is a matter of just 3 minutes...
I encountered the same issue of taking too much time to install mysql community installer.I tried 3 times by cancelling the installation and restarting to perform a new installation.But had same issue. I tried 2 things
First to end all tasks associated with installation which I performed for installing mysql using Task Manager
Reinitiated the installation but didn't solved my issue.
Secondly tried to install through Windows Powershell as admin, which solved the problem.
Click on the Windows icon/start on the bottom left corner.
Right click and select the option Windows Powershell (Admin).
A pop up window will ask Do you want to allow this app to make changes to your device?....Click Yes.
Now cd to your downloads folder/wherever you downloaded the .msi file (For example cd C:\Users\MYPC\Downloads).
Once you reach to the folder where the .msi file is kept, run the following command.
.\mysql-installer-web-community-8.0.23.0.msi (Note: this is the version which I have downloaded, modify as your version).
I have PHPStorm, but when I'm writing native function (for example str_poss, return, parent...) it very often freeze for about 10 seconds. I have no idea what I'm doing wrong. But it happen to me on Windows7 and on Ubuntu also. Has anyone same trouble? Thanks.
PHPStorm used to "lag" for me before quite often too... but I managed to fix it in the following ways (It did take a bit of tweaking/experimenting though to get it to work! But now it is blazing fast once again!)
Here is what I did to optimize it:
1) If you are on Linux - Make sure you are using Oracle Java on your system, not Open JDK
From: https://intellij-support.jetbrains.com/entries/23455956-Selecting-the-JDK-version-the-IDE-will-run-under it says:
On windows: "JDK is bundled with all the product installers and it's recommended that you will use the provided JDK version unless there are any specific issues.
32-bit JDK is located in IDE_HOME\jre directory and is used by the 32-bit product executable.
To run the IDE in 64-bit mode you will need to download and install 64-bit JDK (not JRE) distribution and install it yourself. IDE will find and use it from the registry when you run the 64-bit .exe file (available only for IntelliJ IDEA right now, other products can use the .bat file to run in 64-bit mode)."
2) Disable any plugins you do not ABSOLUTELY NEED! Especially any 3rd party plugins you may have installed**
GBC from PhpStorm 7 very slow and sluggish on netbook, optimize IDE for responsiveness? also had some insties:
3) Disable language injections: File -> Settings -> Language injections. un-check as many boxes as you're comfortable with. HTML was the real killer for me.
4) Disable inspections: File -> Settings -> Inspections. uncheck as many as you don't need.
I hope this helps!
I am on a mounted VM drive and everytime I was going back to PHPStorm it freezes for 5-10 sec.
Unchecked the box "Synchronize files on frame activation", in Settings > General > Synchronization, seems to solve the issue for me.
PHPStorm 7.1 on Linux
A solution I found which drastically increased my speed without having to disable any plugins or disable inspections (because they are useful - why would you want to disable them) was to enable OpenGL.
First of all go to: path-to-phpstorm\bin\PhpStorm64.exe.vmoptions
Then add these two lines below the others:
-Dawt.useSystemAAFontSettings=lcd
-Dawt.java2d.opengl=true
This helped me to get that 'eye' logo disappear and show a green tick on 6000 line file in 3 seconds rather than 2 minutes. Amazing how much difference it made.
If you're using JetBrains Toolbox, go into the Settings beside PhpStorm and crank up the "Maximum heap size". I find about 3000 MB is good.
If you're not using Toolbox, find and open phpstorm64.vmoptions and add this line:
-Xmx3000m
It does the same thing.
I had the same problem on Ubuntu. The IDE was freezing regularly on two different PCs (Using a desktop pc at home and a laptop at work), both have as OS Ubuntu 18. The freezing time was about 1-2 minutes.
It stopped after I restart IDE with VM-option: -Dawt.ime.disabled=true

I have the iMacros plugin for Google Chrome installed and I want to be able to run a .iim file from a Batch file.
I have seen many options online but they all seem to work only if you have the actual iMacros program (not just the plugin).
For example, some solutions look like:
C:\Program Files\Mozilla Firefox\firefox.exe imacros://run/?m=test.iim
Also an option that seemed to originally have worked for pluggins was:
C:\Program Files\Mozilla Firefox\firefox.exe http://run.imacros.net/?m=test.iim
But this apparently has not been working for some years now.
Are there any options to opening a iMacro file from a Batch file, only having the plugin?
Thank you.
Well, it depends on the version and OS of your computer. If you are using Windows then you might want to check to see if that version is compatable with what you are trying to do. If you are using Mac then make sure your iOS is compatable as well. Different versions of OS do different thing. For example, Windows XP batch filing does things differently than from Windows 8.1 or Windows 7.
Another example:
:start
Color 0a
Echo hello world.
Pause
:end
Cls
Color 0b
Echo hello again.
Pause
This will work in Windows 8 because it allows for color changes when cls clears the screen. However, this will not work in Windows 7, or when I tried it didn't work.
I have a very intermittent issue (and now constant failure) launching gnu-screen on OSX from hudson. I have a shell script that does just this:
#!/bin/bash
screen -dm -S foobar
From the command-line as the hudson user this works just fine, and this screen session show up with screen -ls. From the hudson task this does not work. It used to work for a few hours and I have no idea why it does not work any more.
What I've tried so far:
Put the screen command into a separate bash script. Eg. /tmp/foo.sh
Put path prefixes in case the screen command is not found. But screen -ls works just fine, so that's not it
Run screen in non-detached mode, just as a test. This fails as expected with "Must be connected to a terminal.". So this means that screen at least is thinking of doing the right thing.
Run screen as a LaunchDaemon that i start with a launchctl (create the plist file as OnDemand). Same problem.
Is there some way I can debug what's going on? I can't think of how to figure out why things are not working and I'm completely out of ideas. And I don't see any logs that might help either.
My System is: OSX 10.6.5; screen ver. 4.00.03
Update:
I just thought to look in /var/log/system.log and I see:
Feb 24 23:19:00 macmini2 com.apple.launchd[1] (0x1037c0.anonymous.screen[57291]): Switching sessions is not allowed in the system Mach bootstrap.
Feb 24 23:19:00 macmini2 com.apple.launchd[1] (0x1037c0.anonymous.screen[57291]): _vprocmgr_switch_to_session(): kr = 0x44c
I'm going to have to research this further it seems, but I don't want to go down the path suggested in my first couple of searches for this error, which are to install fink version of screen, or to build screen from source. I'd rather keep the machine as is if at all possible (though I'm not against compiling screen from source if that's the only solution).
I've found a solution to my problem, and I suspect it's bad protocol to answer my own question, but for the sake of others who may have this issue, here's how I got around this ..
The easiest/only solution seems to be to build screen from source. Steps are very simple and straight-forward:
git clone git://git.savannah.gnu.org/screen.git
cd screen/ && ./mktar.pl && tar xfz screen-4.1.0.tar.gz
cd screen-4.1.0
./autogen.sh && ./configure && make
sudo cp screen /usr/local/bin/
/usr/local/bin/screen --version
Using this new screen for all daemons or background processes (eg. Hudson's shell launcher, cron'ed tasks that try to use screen, etc.) works very smoothly. This also keeps the system screen (/usr/bin/screen) unaltered.
References:
This apple forum thread is what gave me the idea to build from source.
I just found this stackoverflow solution. It's basically the same solution, so I've voted it up.
