How to replace text in PDF documents?
bj flag

When I am modifying a PDF document, there is a situation that the same name or number needs to be modified to the same content. If there is a replacement function, it is much more convenient than to find and modify one by one. Both Word and Excel have this function, so does PDF also have this function?

I have been a Mac for a number of years and I am hoping to become a Penguin Fan for the purposes of technology development.

I am in the process of developing connected technology which requires TCP connection from vehicle mounted devices.

Can you advise on how I can create a TCP Socket please. I will need port 2095 to be open and to accept connections when the devices power up.

I no longer have permissions to create/resize/mount/unmount any partitions in my system
in flag

I can access and edit in all of my current harddrives. But I can't create a new partition anymore. I can force create a partition in gparted or using 'sudo gnome-disks', but then it keeps giving me an error message when accessing that partition. My other drives it just gives me a udisks-error-quark, 4 if I do anything besides read/write on the harddrive.

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.
