Transparently tunnel HTTPS using squid with SNI filtering
cn flag

My requirements are:

  1. The proxy should be transparent.
  2. I should be able to filter websites by domain name.
  3. I do not want to decrypt traffic. I'm looking for an SNI sniffing based solution -- no installing certificates on clients.

There are plenty of answers floating around but they are either incorrect (claiming you need to decrypt traffic in order to do this) or incomplete.

Redirect IP to another if not available
tr flag

I have 4 IPs something like that

  1. 10.10.10.11
  2. 10.10.10.12
  3. 10.10.10.13
  4. 10.10.10.14

and two ports 1000 and 1001.

my Linux server should connect those IPs with ports. Now I want to make this process automatic. To be more precise, the server tried to connect 10.10.10.11:1000 but it failed now it should try to connect 10.10.10.11:1001 automatically and so on. The problem is that I do not know how to do it. ...

Oracle : Effect of Stale Partition Statistics on Performance
eg flag

Our production database tables are range partitioned based on date.

Some of the tables and indexes have hundreds of partitions. And some of partitions which are old ( based upon partition key ) have stale statistics. These partitions are most likely not being accessed by our queries.

Sometimes the server exhibits performance problems but we cannot be sure whether the problem is due to those old part ...

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.
