403 forbidden on individual Apt packages
jp flag

I am trying to create a Docker container based on Ubuntu 22.04. When I apt-get install packages, I get a weird error: several dozen, sometimes a few hundred, packages succeed without issue, then one individual package will fail with a 403 forbidden error.

This issue is intermittent. When one package fails, it will consistently continue to fail when I retry the Docker build. But once I clear the Docke ...

I use an ASUS X553MA running on Ubuntu 22.04.2 LTS.

The entire visual component would go dormant with no hint of recovery, including the cursor. uname -r gives 5.19.0-46-generic.

Merge PDFs, keep TOC and Page Numebring from original PDFs

The goal is to merge multiple PDF files. The files already have the right numbering and the first pages have Roman numbering which should be conserved. The files also have PDF-ToC/bookmarks that I would like to conserve.

Using sejda-console I was able to conserve the PDF-ToC/bookmarks but not the page numbering.

Sudo access using AD without using FQDN

I've been able to get my server setup where it will allow me to use my AD credentials to login, and sudo works as well, but only if I sign in using [email protected].

How to make any app popup/drop-down on screen (like yakuake)

I love the Yakuake console: with a single key (F12 I believe), you get a terminal that drops-down on top of any app you are currently using. Another tap on that key, the terminal goes away, and can be called again any time (with session preserved). I find it way easier than having to go through alt+tab to find the console I opened 10 minutes ago, possibly on another desktop.

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.
