Automatic Browser Tab Refresher | Forum Promotion

How many of you use addons to your browsers, that allow you to refresh any page/tab, at any rate you want it to, to stay up to date on something? I have one for Mozilla Firefox, and Google Chrome. I generally use it to keep tabs of certain forums, while I am not looking directly at it. For example, I may use it to refresh FP every few minutes or so, or leave it running on a 30 second refresh of the whose online page. Granted, not all the time. I personally hate running it on the index of XF forums, as most of them have the automatic stuff on the index.

 

sql server – Troubleshooting an automatic failover in 2 node multi subnet AG

I am trying to troubleshoot an automatic fail over that happened on our below infra- both of below running on HYPERV VMs

SQL1 – 8 cores 64 GB RAM – No load running (Primary) running on
SQL1SQLins

SQL2- 8 cores 64 GB RAM – No load running (secondary) running on
SQL2SQLins

Both are running SQL2017 (RTM-CU16) enterprise

While browsing in sql error log the very first error message it starts

A connection timeout has occurred on a previously established
connection to availability replica”SQL2iSQLins with
id{3w17383381-e4y2e483y-u92u329}Either a networking or firewall issue
exists, or the endpoint address provided for the replica.

Looking at MS documentation -> here seems above has been resolved and should not be applicable for SQL2017. Is it true or anyone still has faced this issue?

After 2 minutes in error log i see messages saying ” Always on Availability group connection with secondary database established for database bjsas on replica sql2sqlins”

But soon again in a minute i see
“The local replica of AG-VBDR’ is preparing to transition to resolving state and all failover messages

What happened if MS saying issue is fixed or am i looking in wrong direction?

Do MySQL can do automatic EXPLAIN on every query?

We only have two Junior DBAs, no Senior DBAs, no one to guide us. We need to review each and every query for almost 30 large projects. Each query took between 5 minutes and two hours depending on the query. As a reviewer, it was a real drag on my time.

My question is, do MySQL can do automatic EXPLAIN on each query, without having to run EXPLAIN by hand and log the result of un-optimized queries? Or maybe by cronjob? If possible, how to do this?

debian – Automatic restart of isc-dhcp-server

I’m a Debian and Raspbian newbie, and have a question about automatically restarting the ISC DHCP server.

I have a Pi running Raspbian and the ISC DHCP server at a remote site with flaky power. Everything’s on a UPS, but when the Pi comes back after power loss and UPS battery drain, systemctl shows the DHCP server status as failed.

I think this is an order-of-operations issue, where the Pi comes online before the router or switch are up, and can’t start the service as a result.

How to get systemd to handle automatic restart of the DHCP server when it gets in this state?

I’m aware of the “Restart=always” command for systemctl, but can’t find a unit file for the DHCP server to append it. The dhcp client has one, but not the server. This puzzles me, since the output of “systemctl list-unit –type=service” includes the DHCP server.

Thanks in advances for clues on getting this service to restart.

settings – Why does Automatic Graphics Switching keep re-enabling itself without my involvement?

I disable Automatic graphics switching under Energy Saver, as it significantly slows my Macbook Pro (10.15.5). Yet this checkbox keeps getting re-enabled when I have not touched it!

How can I prevent that? Or failing that, how can I disable this from the command line? (I’ll write a script to run every ten minutes.)

If everyone is supposed to be equal, wouldn’t bringing back affirmative action give automatic preference to some people?

several years back, a guy who sat on the admissions board of an Ivy League medical school said that, if they went strictly on merit, 100% of incoming medical students would have been Asian females for three straight years…

he said, quite simply, that they could not let that happen…and cited the university’s commitment to “diversity” as the primary reason…
