The format of the examples you have given look fine. Here are 2 thoughts.


Perhaps you are editing the file directly rather than via 'crontab -e', in which case cron would not receive a signal...

If your sole objective is to run Ubuntu inside Virtualbox as per your first sentence, then there is no need to install Windows in a separate Virtualbox VM. There can be reasons for choosing to do...

This ought to do it:


AccountA$ chmod go=r ~/.Xauthority # Allow AccountB to copy this file
AccountA$ su AccountB
AccountB$ cp ~AccountA/.Xauthority ~

For a program you need data structures and algorithm. You've made a start at some data structures but you are lacking an algorithm. Choose an algorithm...

Thanks. That's helpful so I can now do:


$ git clone myalias:/path/to/repo.git

but that still didn't work - same timeout error.

It turns out that for this server, the URL must have a...

We've recently changed hosting provider and are having trouble getting git working.

ssh works with authorized_keys so:


$ ssh user@myhost -p NNNNN

works, giving me a shell (albeit a...

We would need to see some code in order to be able to determine why it is not doing what you expect. However, as I understand it, when a pthread exits, it does not raise any signal, nor does it when...

The reason the new size wasn't recognised appears to be because there was a snapshot of the VM. Removing the snapshot has solved the problem.

Format: vdi, Dynamically allocated storage. as per OP. Are you suggesting that resizing a dynamically sized vdi doesn't work?

Thanks for your replies. However, Windows sees the disk (not the partition) as still only 100GB. Therefore there is no free space into which to expand the partition. Thinking that this might be a...

The host system is Ubuntu Studio 20.04. This hosts a Windows 10 VM with 100GB disk which I want to increase to 150GB.

I have done:


VBoxManage modifyhd Win10Dev64-disk002.vdi --resize 150000

There would be only one copy of the code segment in memory. However, I'm not sure what you mean by reentrant. What I understand by that is: https://en.wikipedia.org/wiki/Reentrancy_(computing)

Beaten to it.

Is that your system time? If so, can't you set it to something more realistic?

Welcome to the forums. Pasting output between CODE tags is preferred to external links to images.

"/5" is not a valid format for the minute field. If you want the job to run at 5 past the hour...

Everything you mention is completely normal on Studio 20.04. What makes you think there is a problem?

If you need some reassurance, the CRON messages in auth.log will match with CRON messages in...

Typo. It should be modprobe not modprob.

Your tree structure mentions .gpr files. Your use statement refers to .grp files. gpr != grp.

Isn't this new thread just a duplicate of yesterday's https://ubuntuforums.org/showthread.php?t=2442088 ?

That first line asks for the script backup.sh to be run once every minute from 02:00 AM until 02:59 AM. That seems a bit odd... but if that's what you intend then ok.
Please elaborate on "this...

Is /backups/storage-mnt a native Linux filesystem, i.e. not Fat32, NTFS etc.?
How is it mounted?
Can you write to Projects? e.g.

ssh remtusr@192.168.10.24 /usr/bin/touch...

I'm assuming this is Ubuntu Studio 19.10 and not 9.10. The following works for me.
1. Get credentials from /etc/mysql//debian.conf
2. Start mysql using those credentials.
3. Then

The default jre in both 19.04 and 19.10 is openjdk-11-jre, i.e. java 11. See https://packages.ubuntu.com/disco/default-jre and https://packages.ubuntu.com/eoan/default-jre

glibc's malloc is thread safe. I think that mallocs that you are likely to come across in this day and age will be thread safe. It is guaranteed to be in C11 (but not in C99).

You will not...

pthread_create succeeds, then immediately you return from main. returning from main terminates all running threads and stops your program. So your mt function never gets chance to print its message,...
