PHP 7.4 on Ubuntu 18.04 (bionic)
ru flag

I'm having trouble getting PHP 7.4 to install on 18.04 now, as it seems to depend on a version of libc6 that is not available on 18.04.

I have no tried building from source as I would like to avoid that if possible.

Get all hostnames in local DNS for current Windows server
ec flag

I've deployed BGInfo from SysInternals to all of our servers, both physical and virtual. However, a few of our servers have multiple hostnames to support "backward compatibility" with some of our legacy software systems after a server was replaced or its functions were merged with another server. In some cases, this may include several "alternate" hostnames that go back several years.

EXAMPLE:

I have a vServer (16GB RAM, 6 vCores) running Ubuntu Server (Linux 4.15.0) with a few docker containers.

A few days ago, I deployed a new container, and it would simply refuse to start with weird native crashdumps from docker-compose, most including these error message:

Matrix + coturn: TLS not working

I'm trying to get (as a Docker stack) Matrix Synapse (matrixdotorg/synapse) together with Coturn (coturn/coturn) to work. Matrix is fully working with TLS certs. Also the coturn server works with disabled TLS without any problems. But when I enable TLS then it fails completely.

iOS 14.7.1 + Exchange 2019 - Server certificate no longer trusted

After upgrade to iOS 14.7.1 I am no longer able to sync my email/calendar/contacts with company Exchange 2019.

Our Exchange uses certificate issued by our enterprise CA and these seem to become untrusted after the upgrade to iOS 14.7.1.

Hybrid AAD Network - Network Share Problems
in flag

My work is currently migrating from a fully on-prem environment to Microsoft 365 and SharePoint. However, due to various reasons, we've had to keep our on-prem domain active. Our domain controller runs on Windows SBS 2011 (Yes, I am aware that this is very, very old software, but the budget hasn't been there to upgrade it). Therefore, we have a virtual machine running Server 2012 that runs AD Sync. We h ...

The `containerd` daemon fails to start due to IO error (and subsequent segfault)

Running on Manjaro Linux, kernel 5.13. After system update, containerd service fails to start and segfaults after it cannot run garbage collection. Logs are attached on Pastebin.

After short investigation, I found out that problem is that contained receives IO error when it tries to write to its database (particularly to the file /var/lib/containerd/io.containerd.metadata.v1.bolt/meta.db). However, this  ...

Ubuntu server 2020.4 network bridge for KVM not starting

I'm attempting to configure a bridge to be used for a KVM host on Ubuntu 2020.4 LTS. The basic configuration with netplan works, but the bridge does not work until I manually add the ethernet interface to the bridge with brctl. But when doing that the connection becomes flaky and eventually stops. How can I have this start up automatically when booting ? What is wrong to make my connectivity go away  ...

How to protect 15-amp circuit from UPS with 20/30-amp draw
az flag

I managed to pick up a great deal on a CyberPower OR2200LCDRT2U UPS. Unfortunately this box has a NEMA L5-30P input plug (NOT a L5-20P as specified on the product page). In the location I'm trying to set this up, I only have a 15-amp circuit with a 15-amp breaker. Further, it's basically on the opposite side of the house from the breaker, so I suspect that running a dedicated 30-amp line would be  ...

TCP packets split into ACK and PSH,ACK in Docker

I am working on a mainly TCP based Game Server and just tried to run it in a Docker container. However, I observed that when accessing the Server in a container (via the Game Client), the packets for every SeqNo are split into two parts.

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.
