New VMs are provisioned with a startup script (bash), which, on rare occasions, fails in some way. However, the VM is still able to start, launch it's workload, and pass it's health checks.

Is there some setting in GCE / MIGs that says "if the init script does not execute successfully ...

Windows 10 random time outs

The repeater is wirelessly connected to the router and added to a mesh. I am locally connected to my repeater with a RJ45 cable, directly connected to my motherboard NIC.

TCP slow start and duplicate ack
au flag

In TCP slow start, what happens when 3 duplicate ack is received. I am aware of the recovery process in congestion avoidance, however I read a blog post that if 3 duplicate acks are received in slow start, TCP perform fast recovery. I was under the impression that whether it is RTP or 3 dup ack, in slow start, TCP fall back to initial cwnd value.

"The final way in which slow start can end is if  ...

mtls configuration in NGINX - upstream chain validation
us flag

I have several questions regarding the mtls configuration in NGINX:

When configuring with ngx_http_proxy_module, to verify upstream certificate, does upstream's TLS chain have to be stored in a cert which is used in proxy_ssl_trusted_certificate property? or just the Root CA certificate? or intermediary and root?

The server's TLS chain looks approximately like this:

What is the difference between 0.0.0.0/0 and 0.0.0.0/1?
br flag

In the history, I mostly used 0.0.0.0/0 for "match every IP address". Recently, I saw a 0.0.0.0/1 subnet filter.

What is the difference between 0.0.0.0/0 and 0.0.0.0/1 and what's the practical use of 0.0.0.0/1?

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.
