| Cannot add accent marks on character, as accent marks immidiately appear before the next key press Posted: 05 Jul 2022 11:24 PM PDT In short, I am trying to type the acute e character. For some reason, on my office computer (Linux Mint Cinnamon), I cannot write the character as I am used to. The way I would normally do it, is
So instead if é, I get ´e. It is the same for other characters, for instance if I wanted ñ, I would press My keyboard layout is Norwegian. |
| Posted: 05 Jul 2022 11:07 PM PDT OS - SLES Version - 15-SP3 I am successfully updating the external network interface name from ens33 to eth0. On reboot, the ifconfig is giving output with eth0 as a device and SSH is also turned on. I need to turn on the SSH without a reboot after performing the same changes(external network interface name change from ens33 to eth0). Can someone please help me to know how can I do that ? |

| Why is play Minecraft on mx linux so smooth Posted: 05 Jul 2022 10:00 PM PDT Lately I've been trying to experiment with some linux distributions, then try to play games there such as minecraft. I tried:
I could use MX Linux as the main distribution. However, because a lot of information says that some of the most Ubuntu packages can't run on MX Linux, I'm also hesitant to use it. Can someone explain why minecraft is running so efficiently on MX Linux. Because I want to configure the same settings on Ubuntu to run smoothly like MX Linux. I think that this is a matter of drivers or kernel compatibiliy, but I'm not sure because there are many factors that determine linux performance. Spec:
I didn't try to another game than Minecraft, but I will test next. |
| Posted: 05 Jul 2022 08:38 PM PDT I was working on downloading iTerm2 on my M1 2020 MacBook and ran into a problem while downloading homebrew. In order to reinstall, I deleted /opt/homebrew directory and now all my files are gone. I have tried to recover those files to no avail. How can this be?

| Pinging Result between A & B KVM guests in same subnet Posted: 05 Jul 2022 08:26 PM PDT I have a Ubuntu 20.04 KVM host running with a number of web and application VM guests. Suddenly, there is 1 web proxy server can't be connected. NOTE: there is a network team to manage the network I try to ping from web proxy server to all other machines at KVM management console. It works. 192.168.11.61 (proxy) -> 192.168.11.60 (Host), 192.168.11.62 (app1), 192.168.11.63 (app2) REMARK: in order to troubleshoot, I disable ufw for all guests and the host. Then, I try to ping 192.168.11.61 (proxy) from all of the above. None of them is working. Interesting Findings Then, I try to ping 192.168.11.61 from 192.168.11.62. Meanwhile, I ping to ping 192.168.11.62 from 192.168.11.61. At this time, both of them are pinging each other with reply to each other. Once I stop the ping action from 192.168.11.62, again the 192.168.11.61 cannot be reached. For the above scenario, I have never seen it. The network team is saying that it is likely a problem of my KVM & firewall settings. ** Additional Notes **

| Posted: 05 Jul 2022 08:41 PM PDT I am not sure how to look for this, so please direct me to the answer if it's around somewhere. I also want to apologize in advance if the title of the question is not clear, I couldn't think of a better description. This is a simplified example of what I am trying to do. Let's say I have these two directories that are on different hard drives:
Now, what happens is that if they are ordered alphabetically, dir1/ and dirA/ are related, so I want to extract some files from dir1/ and copy them inside dirA/. The same happens with dir2/ and dirB/, dir3/ and dirC/, etc. I am sure there is an easier/better/more correct/faster way to do this, but right now I am stuck on this idea and can't think of any other way, so what I am thinking of doing is to: I would be doing this on the assumption that it will always loop both folders in the right order, but I am afraid that something could go wrong. Is there any other way of doing it that I ignore? Thank you very much for any help you can provide! |

I would like to print only first line and skip that second line. Second field numbers increasing up to ~1300 and decreasing to 1 after.

| how to run "play start" as a linux service Posted: 05 Jul 2022 09:09 PM PDT I want deploy a play framework web application from source, and run "play start" to start the application. I wrote a startup script in /etc/init.d/ which execute "daemon play start" when service start, but the service start command did not return. I guess it's because play start is waiting for me to give him a Ctrl+D. "nohup" can fix it, but with "nohup", I have to run "kill -9 xxx" to stop the application, which is not what I like. What's the best way to run a play framework application from source as a linux startup service. Thanks a lot. |
