I am unable to edit email message body in evolution following update
in flag

I updated my system and now when I open an email to send, I can add header information but not the body of the message. Same with trying to reply to an email. No cursor will parse to the body of the message. It's read only.

How do I re-enable my message body in evolution?

Performance, Security and Scalability of nginx proxy vs ssh tunnel
in flag

I'm wondering about the difference in performance, security and scalability for nginx and ssh tunnel for a web application.

For my case, I have a VPS set up, whos only job is to forward the traffic to my home router. This traffic travels between the 2 servers unencrypted (HTTP) and I think it would be easier to use a SSH tunnel for this case instead of having to set up HTTPS twice.

OpenVPN adding static ip for client dynamically based on a script
cn flag

In my VPN logic all of my client certificates have the folowing CN template:

number.mycompany.com where number is between 2-65536

For each CN I add a config file which looks like so:

$ cat 65501.mycompany.com
ifconfig-push 10.22.255.221 255.255.0.0

So basically based on the CN number area I configure the static ip in the relevant file, conversion from number to ip logic:

Erasure code overhead for heterogeneous hardware

Cache gems for every build on GitLab Runner

I have a GitLab Runner installed on a Ubuntu server. It uses 'docker' executor.

I want every CI job which executes on this runner to use the same Ruby gems cache, to prevent downloading from rubygems.org the same version several times in a row.

There seems to be two solutions:

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.
