How can I identify cause of Azure intercontinental bandwidth?
us flag

We have a small Azure Virtual Desktop setup with about 12 users. There is storage for fslogix containers, and a file share. We also backup a small on-premises server to Azure. All the Azure services are in one region and set to LRS (Locally Redundant Storage).

On Saturday we were charged £16.97 for "intercontinental bandwidth" on that single day. Concerned not only about the cost but also the po ...

accounting GPU compute time on HPC clusters

How do you account for GPU compute time on your HPC clusters ?

I have a growing, and quite heterogeneous (SXM4 A100s, PCIe A100s, NVlinked V100s, PCIe V100s, T4s, AMD cards arriving soon etc...), GPU partition on an HPC cluster (mixed hardware Debian servers running OAR scheduler).

Traditionally, we accounted compute time as seconds per core per job. Despite CPU and memory variability between nodes  ...

MariaDB using much more memory than it should
sa flag

We are using MariaDB 10.3.32 on a Ubuntu 20.04.4 machine with 6 GB of memory, about 20 applications running on it. Databases are all InnoDB.

Even with mostly default settings (see on the bottom), memory usage increases from day to day, seemingly non-stop. After about a month of uptime the OOM killer starts doing its work.

According to this SQL statement, peak memory usage should be around 600 MB. I  ...

Apache 2.4 .htaccess Set Headers for error pages
aw flag
MW.

I am setting some headers using .htaccess for a web page, f. e.:

<IfModule mod_headers.c>
Header set Strict-Transport-Security "max-age=31536000; includeSubDomains"
</IfModule>

This works fine for usual page access, but the headers are not used on error pages like 404 Not Found and 403 Forbidden.

Is there a way to set Headers for error pages using .htaccess?

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.
