问题 I have the following problem and I need to know if there´s a way to fix it. I have a client who was cheap enough to decline buying a backup plan for his postgreSQL databases on the main system that runs his company and as I thought it would happen some day, some OS files crashed during a blackout and the OS needs to be reinstalled. This client didn't have any backups of the databases but I managed to save the PostgreSQL main directory. I read that the databases are stored somehow inside the

Retrieve/Recover deleted Netbeans project

由 跟風遠走 提交于 2019-11-28 05:43:24
I was just working on my Netbeans project and accidentally deleted it and don't know how to recover it. Is there a tmp folder that the deleted project is stored in. Or am I forever doomed? Thanks, Lucas http://www.recuva.com/ saved me countless times when I first started with Visual C# opening the IDE and making mini programs without saving. All your files are stored in a temporary folder and exiting Visual C# wipes them. Just do a recuva scan and sort files found by modification time. Deleted files are recoverable, overwritten files however are a different story, so run the program as soon as

If they have, then you should be able to git your changes back by looking for them in git reflog . 回答2: Foy anyone who is facing

Linux wrong path exported. How to recover ~./bashrc file

由 帅比萌擦擦* 提交于 2019-11-27 15:52:05
While I try to set java path on ~./bashrc file i exported like: PATH=/usr/local/jdk1.6.0/bin export PATH which I guess makes all the other path missing.So it makes me any of the core command like cp not working. I am aware the default ~./bashrc file will be there on /etc/skel . But since none of the common comments working i am not able to copy it. Is there any way we can revert original ~./bashrc ? Put something like: PATH=/your/jdk/bin/path:${PATH} export PATH That way, your path gets prepended to the regular PATH environment. And simply log out and log back in to reset your environment. Or

How to return a value in a Go function that panics?

由 别来无恙 提交于 2019-11-27 14:50:19
My Go function is expected to return a value, but it may panic when calling a library function. I can use recover() to capture this in a deferred call, but how can I return a value in this case? func MyFunc() string{ defer func() { if err := recover(); err != nil { // What do I do to make MyFunc() return a value in case of panic? } }() SomeFuncThatMayPanic() return "Normal Return Value" // How can I return "ERROR" in case of panic? } You can use named result parameters . Name your return values, and in the deferred function when panic was detected, you can change the values of the return

How can I detect a hang in QEventLoop?

由 孤人 提交于 2019-11-26 16:29:18
问题 I am not sure if the title of my question is formulated correctly, so to explain what I really mean, consider the following example: I create a QApplication and a QWidget with a QPushButton on it. Then I attach a handler to the click signal from the button that looks like this: void MyWidget::on_pushButton_clicked(){ //Never return while(true); } Finally I start the event loop for the application and when I run the program and the window shows up click the button. This will in my case stall
