AWS Deploy without deleting files

I'm new to AWS and I'm having trouble with deploying a project. Every time I deploy using the CLI, all the files created by my application is wiped.

Now I'm sure I'm just falling victim to my own incompetence, but I'm having a hard time tracking down the right process/design to ensure that I can keep some parts of my data while updating. I suspect I have to save the data to another location outsi ...

Intel x550 NIC rx_dropped packet on Debian 10
cn flag

I have just added an Intel x550T2 10Gb NIC on my Debian 10 server, and noticed that I have a lot of rx_dropped errors. The card is on a correct PCIe extension slot (PCIe3.0 x8). At the moment, it is linked to a 1Gb switch which run perfect with the native onboard Intel i210 NICs. No drop or error on those ones.

Here is some info for the i210 NIC :

SPF Records: Outlook shows fail, Google shows pass

I am using Office 365 for emails, and have configured the DNS SPF record as:

I am running a Graphite based collection, and have a couple of Prometheus only apps that I would like to be able to monitor through that.

KeepAlived UDP Load Balancer with DTLS

I have a cluster of servers that rely on UDP for client communications. Among the few LBs that support UDP there is KeepAlived which however operates at layer 4: I have a minimum of experience with LB of layer 7 therefore, if with KeepAlived I wanted to use DTLS or similar protocols, how should I act at LB level to operate in accordance with DTLS? From my modest knowledge I don't think it's possible: so ...

Latest 0.39.1 version does not allow accessing objects without listing the directory content before

Our servers restart nightly and we noticed that as of yesterday (with the release of 0.39.1) our servers did not properly start up anymore.

We noticed that when we try to access files on a bucket (mounted through gcsfuse) - we get access denied / file not found errors. So for example the following structure:

Restricting traffic between AWS VPCs
za flag

I have two VPCs: A and B.

I want any node in A to be able to open a TCP connection to any node in B, but not the other way around. Any node in B must also be able to open outgoing connections to public internet hosts. What is the best way to achieve this?

Use case: VPC A contains many sensitive internal services, and VPC B contains nodes that run completely untrusted code. VPC A needs to make HTTP r ...

Is it worth it to install and configure fail2ban for an Bind9 authoritative DNS server?

In our project infrastructure we have a nameserver, based on bind9. This nameserver is configured as primary and authoritative, so it is quite important. The question is, should I install and configure fail2ban for the purpose of protecting this DNS server? Is it worth it?

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.
