How to convert DjVu to PDF without increasing file size?
fr flag

I am satisfied with the tools I use for annotating/marking up PDF (highlighting and searching for text, mostly), which is why I want to convert my DjVu files to PDF.

But the converters I have used always blows up the file size. And some do not even preserve the text layer.

What tools are available which achieve both

  • preservation of text layer
  • no explosion in PDF file size ?

On Ubuntu 21.10 on an IMac mid-2011, the built in mic volume is really low, even when:

  • In system settings: the mic input volume fader is at max.
  • In pavucontrol: the built in mic input is at 100%
  • In alsamixer: all the input faders are at the max

but the built in mic volume is still really low.

I am using a Normande - VSIM1001 laptop that originally came with Windows 10 Home. I have installed Ubuntu on it but cannot get the wifi to work. I have also tried installing Xubuntu 20.04.3, but still encounter a No network devices available message.

When I plug in a USB dongle, it recognizes it and works fine.

How can I resolve this issue?

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.
