HAProxy - Images dynamically generated on page load, client has to hit refresh
jp flag

Clients access our web server through our HAProxy reverse proxy (2.4.3-4dd5a5a).

Some web pages contain JPG images which are dynamically generated on page-load. When accessing through haproxy, the client has to hit "refresh" for the generated images to appear.

Is there some kind of time-out setting that needs to be adjusted on the proxy (backend?) to delay the loading of the JPG image until it is ge ...

I have a user that needs to connect to a remote machine M (via ssh) and run one in a fixed set of commands (say N in total).

These commands rely on python, libraries thereof, and privileged access to the network (which machine M has).

Prevent nginx to cache certain parts of a site

Everything works fine on our website, but we have the issue that when a customer buys a course, nginx cache prevents customer to see that purchase on his/her space, this is fix when nginx cache is erased. So we want nginx not to cache that specific process of buying and reflecting the purchase.

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.
