What is the best metric for auto-scaling GPU instances for machine learning inference in the cloud?

We have an API in AWS with a GPU instance that does inference. We have an auto-scaler setup with the minimum and maximum number of instances, but aren’t sure which metric (GPU/CPU usage, RAM usage, average latency, etc) or combination of metrics should be used to determine when a new instance needs to be launched to keep up with incoming requests.

Are there best practices in regards to what met ...

Problem

I can't use ipmi to control fan speed.

I have an X570D4U-2L2T motherboard with a Ryzen 5600x and am running Ubuntu 21.04.

Can the community advise how I might use ipmitool or ipmiutil to control the fan speeds – either to set a constant value or to set a curve?

Constant timeouts when conecting from LAN to services behind a reverse proxy
cn flag

years after my first home server died, i've decided to have one again. This time for the sake of learning and having more flexibility i'm doing it with docker containers. The thing is, i've set up a reverse proxy with nginx and the let's ecnrypt companion, to provide SSL encription & to avoid forwarding more ports on my router.

This works pretty much flawlessly, from my phone with mobile dat ...

Best practices for database with direct user input
cn flag

I’m currently working on a dynamic project, in which the users feed the database with new objects/data. Other users can later access the data other users provided.

Because the data’s coming directly from the user, I will sanitize the inputs. Nonetheless I don’t want them to feed data directly into my main database, so I thought of putting a new, temporary database in front of the main one.  ...

Are MX record names important?
cn flag

When creating MX records for a domain, is it important what they are called?

I want to manage email through a remote service and have added the appropriate destination and priority. The service that is used to manage the domain (cpanel) does not allow the MX record name to be called @ so I gave it a name like mx1.mydomain.com

Is this is a problem when setting up MX records?

Nginx configuration to make open ports look like they're closed
cn flag

I have ports 443 and 80 open on my firewall and pointing to my Nginx reverse-proxy server. I have Nginx setup so that if anyone accesses ports 443 or 80 using my IP address Nginx returns a 444 error. I would like to set Nginx up in such a way so that if someone does a port scan of my IP address they won't even see the ports as open. Is this something that's possible? My current config looks like this: ...

How do I hook up a business modem with 6 ports to a switched network?
no flag

I have a small business modem that has 6 ports on it, each being a static IP.

My network has grown however to the point where I have more than 6 devices, so I am moving to use a switch, which has other benefits as well.

Does that make my 6 static IPs redundant? Should I just connect one of them to the switch and NAT everything, or is there a way I can use all 6 IPs?

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.
