Compile the project combined C and objective C by using cmake
fr flag

My project contains both C and Objective-C source code, and I am going to generate makefile using cmake. Basically it was built in MacOS, but now it's going to be used in ubuntu.

So I have installed necessary packages for Objective-C and just added both *.m and *.c files together into the config, but it isn't compiled. Following is the error message.

Ubuntu 20.04.3 noisy image after login
ve flag

Booting works until login, then after entering my password I get a noisy screen (no graphical interface?). Luckily, I can press Ctrl+Alt+F5 to switch to a TTY (full-screen terminal). My first idea was to bring the system up-to-date before looking at the possible other solutions

sudo apt update
sudo apt dist-upgrade
sudo reboot

but this has not helped. Neither did reinstalling the the login manager: ...

Screen rotation works in liveusb mode, but not after installing to disk
gb flag

I tried many distros to see if screen rotation works for my Yoga 6 Ryzen 5 laptop. Finally, it worked on live ubuntu installer tryout perfectly. It also had a Lock screen rotation option in dropdown menu. But after I installed it, it is not working and also not showing the option either.

So there should be something I can install/enable to make it work again.

/usr/bin/python3: No module named pip
mm flag

Why does this happen?

python3 -m pip install --user --upgrade pip
/usr/bin/python3: No module named pip

Surely this should be easy to fix.

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.
