I have several machines in my network which are not using proxy to outbound.

I want to redirect all traffic, using route tables, to an appliance so that appliance ingests that clean traffic and send it to a proxy, or at least to a proxy socks.

Is there a tool to conveniently mount&inspect aws ebs volumes?
cn flag

I am currently in the process of cleaning up some unused EBS volumes in a quite messy AWS account.

Before deleting the volumes I want to make sure that nothing vital is being deleted, so I occasionally need to mount the volume and see what is inside.

The problem is that the volumes have not been labelled and in most cases I don't even know what file system is supposed to be used when mounting the vo ...

I have a problem for which I have not found a solution anywhere.

The problem is that we have deployed proxy servers in front of our game services and here we use haproxy for tcp traffic and nginx for udp traffic.

Everything works fine, meaning players can connect and play, but at random, our players are dropped from the servers for a reason: timeout

And the nginx error log gives this kind of error:

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.
