Serial Line Tester (not just a monitor)
cn flag

I'm looking for a serial (RS-232) line tester, not just a monitor. I want to introduce delays and errors for test purposes. I can find plenty of serial monitors, but none that have features for testing by simulating adverse conditions. Any pointers?

Accessing Ubuntu via X2Go (or similar remote desktop) with OpenSSH based certificates?
in flag

Is it possible to connect to Ubuntu using OpenSSH-based certificates with X2Go or some equivalent Remote Desktop system?

That is, where you have IdentityFile and CertificateFile in the ssh config.

I haven't found yet a way to get X2Go to do this, even with the alternative convention of providing the usual id_rsa and then naming the certificate file id_rsa-cert.pub.

Can I recover a db password?
bd flag

For our project in GCP, the app has a production Postgres db instance, we don't have the current password, therefore we can't access the db other than through the app. If we change the password, then we can access the db let's say using PGadmin but the app becomes inaccessible. We don't know where in the code that was deployed the password is. Is there any way to recover this password? or where in the c ...

docker/podman container with public IPv6
br flag

I have got a server with IPv4 address and IPv6 /64 subnet (let's say 2001:db8::/64), both public. Server itself has the following IPv6 address: 2001:db8::1/64. The gateway is fe80::1 (which causes problems with docker/podman, because it's not in the same subnet).

My goal is to create docker/podman container (WWW server, for example) with its own public IPv6 (let's say 2001:db8::2/64). From my understandi ...

I only noticed this when I always get disconnected playing online games. So I investigated pinging Google.com or 8.8.8.8. So I noticed I get high ping or even request timeout on regular intervals. So I pinged my router/gateway (192.168.xxx.xxx) and got the same results.

enter image description here

But I tried pinging the same wireless network using my Mac and Android phone and I don't see this issue. It must be my Windows laptop. I ...

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.
