How to install latest ca-certificates on Ubuntu 14
sm flag

I have an Ubuntu 14.04.5 LTS installation. It just recently became unable to verify modern Let's Encrypt certificates. The current version of ca-certificates is 20160104ubuntu0.14.04.1. apt search ca-certificates tells me that the package is upgradeable to 20170717~14.04.2 from trusty-updates, but I think that's probably not modern enough.

I see ca-certificates version 20210119~18.04.2 in bionic-upd ...

LMMS isn't starting on raspberry pi 4b runing Ubuntu 21.04
cn flag

It started two or three days ago. I installed ubuntu 21.04 on my raspberry pi 4b, and installed lmms on it. It worked well enough, but one day, I tried switching from pulseaudio to jackd2 as the audio server. I turned the latency down to the lowest possible. (I would show a screenshot, but the lmms gui isn't working.) It shows the startup screen, but now it won't show the gui. Sometimes an error window  ...

Using Alacritty to write LaTeX (with vim) can't launch Evince to preview
eg flag

I use Neovim to write LaTeX files with the Alacritty terminal. After writing the files I want to preview them with Evince. However, Evince doesn't launch. I don't know why. If I use the default terminal, it works!

In Neovim I use VimTeX or vim-latex-live-preview to preview. Both of them work well in the default terminal but not in Alacritty.

Does anyone know why?

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.
