SPF Too Many DNS Lookups issue
co flag

In our scenario, We're running into an issue with our SPF records in route53. We are receiving SPF Too Many DNS Lookups because we are using multiple mail services. Is there a way to resolve this? I saw one thread stating to run a look up on the domains and include them by IP but that doesn't seem too stable of a solution. Another said to us PTR but that seems like the same path. Is there a better way y ...

Information request for alternatives to TN3270/ISPF/OSHELL and more
br flag

I have started a new job which involves daily access to a Mainframe. This is my first experience with interacting with such a beast. My colleague has been helpful in getting me started, but I can't help but think that maybe he has been in the job too long.

Is it really the case that accessing via a TN3270 terminal is still standard practice ? Why can I only open one session at a time ? This is  ...

Add Subject Encoding in Postfix
br flag

How can I use postfix to encode subjects with special characters?

I am using a proprietary software which does not encode the e-mail subject header. If the header contains a special character (for example german umlaut: öäüß) it causes problems on the receiver side.

The software runs on Linux and uses to local postfix daemon to send the e-mails. Can I somehow add the encoding in postfix?

How to limit log size on Elastic beanstalk with Corretto 8/Amazon Linux 2 platform?
in flag

We recently migrated one of our applications to the "Corretto 8 running on 64bit Amazon Linux 2/3.2.12" platform. Now we're seeing the issue that the log files are filling up our disk volume in a span of a bit over a week. We didn't have the issue before.

What's annoying is that we're streaming those logs to cloudwatch, so we really don't need them on the instance itself. What's even more annoyin ...

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.
