using two networks on Ubuntu 20.04
vn flag

I have around 10 computers in the same network, all with 10G network cards who have two network connectors. I would like to create a frontend network for internet and some light synchronization between the computers and one backend to transfer large files (100G each) between the computers. I'm not sure how to set up the computers for them to know that when it's internet they will use the port 1 and one  ...

Alter GTK2 style (only) in Ubuntu 20.04

3x5

I know there's Qt5ct for tweaking the look of QT apps in Ubuntu, but I have a couple apps I use a lot (like gmusicbrowser) which are only stable in a gtk2 version.

In the case of gmusicbrowser, the space around words in tabs is too narrow, and the contrast between colors is too slight for things like highlighting alternating rows. I want to tweak the GTK2 style, or change its theme, without alter ...

No shadows on menus in Firefox 91

After upgrade to Firefox 91, the menus in Firefox no more have shadows around them. This looks ugly and makes the menus less visible on top of the webpage. Is there any way I can bring them back? Maybe some tweak in theme's CSS?

Firefox menus were always styled a bit differently from other applications menus (for example note the difference on separators and submenu arrows on enclosed screenshots ...

Why am I the only one who can connect to my Minecraft server?
cn flag

I'm local-hosting a Minecraft Java Edition server on Lubuntu 20.04, and only people on the LAN can join it. I've set up a port forward for the PC with port 25565, disabled the entire firewall, but nothing works. I tried canyouseeme.org, and port 25565 is open, so I figure it's something with Lubuntu. I set up the iptables rules following this github file: https://gist.github.com/Maxopoly/6c925a1f18f9e2f3b ...

I'm porting older in house software to 21.04. I run rpcgen without error, it creates a ".h" file that has the expected "#include <rpc/rpc.h>", but I cannot locate a package that actually contains the header file that rpcgen expects. Suggestions?

TIA.

Ubuntu does not see whole partition after resizing

I have a 1TB NVME Samsung SSD which had 2 major partitions (apart from efi).

One 325GB which contained Ubuntu, and one about 600GB which contained Windows.

I decided to stop dual-booting to use only Ubuntu. So I booted on live usb, and using gparted, i removed the 600GB partition, I expanded the 325GB to fill the empty space and I fixed grub.

Everything went well except Ubuntu doesn't see the expanded  ...

gnome-shell excessive CPU usage / slowness on tracePersistentRoots

In the last few days, gnome-shell has started performing very poorly. The UI becomes very slow, and eventually almost unusable with a lag between clicks and response taking a few seconds.

The symtomps do not start immediately, but within a few minutes. Killing the process, or restarting it (using ALT-F2 and entering r), the usage (usually) recovers - at least to the point that the rest of the UI is ...

But today I figured out something strange.

Folder home was full due to some files and other stuff that I'm working.

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
