Reminds me of the NET SEND command in windows 2000-xp. Allowed sending a popup text message to specific (or all with a wildcard!) machines on a network.

Sure there were times where such a feature would be convenient ("server going down for maintenance, please save your work", etc), but overall ripe for abuse. They disabled it in a service pack and took it out altogether in subsequent versions.

Back in my senior year of high school during Spanish class I naively used NET SEND to send a message to one of my classmates. The only problem was that I failed to specify the user in the command and instead used *. This ended up sending a message to all computers in the school district.

I remember the computer administrator coming into the class saying “Are you aware one of your students is sending messages to the entire school district?” My heart sank.

I ended up getting in-school suspension. Considering this was my first ever “offense” in school, I felt like a badass going out with a bang.

A classmate did the same, although the outcome was far worse.

We studied at university in the medical faculty, which happened to be housed in the academic hospital. We found out the hard way that the network was not segregated, his netsend command crashed all the ICU terminals...

Just that the guy isn't to blame. That's like saying "By switching off the lights in the break room I shutdown the power in all the operation rooms"

Same, apart from the suspension. On my first computer science class. That was... not fun.

The professor classified me as the annoying kid, until I surpassed his expectations with the first programming excercises :P

I did the same in 8th or 9th grade, but on purpose and I sent a crap ton. The admin stormed in and yanked the laptop out of my hands and revoked my PC privileges for ~3 months. Fun.

I caused havoc in high-school with that. And finding a way of executing binaries inside Novell's Netware thing, via the "Open" dialog within any Office application's Visual Basic macro editor haha

Renaming executables to explorer.exe worked with the application whitelisting solution my school implemented.

That's how we ended up with 8-player age of empires 2 deathmatches after hours ;)

I created a directory with alt+255. It was an unprintable character and showed up last in any dir listing. At most it added an extra new line. That’s how I was one of the only students whose apps didn’t get caught during auditing.

That brings me back. All .exe were blocked.

However it turned out that you could rename them .bat or .cmd and they would execute just fine.

I think Doom 2 multiplayer was extra fun because of the added need to be aware not just of in-game enemies but also the need to be aware of the teacher and be ready to instantly quit at any moment.

Haha, me too :D

Wrote a batch script that used a wildcard - it took them a while to find it and I was very lucky the only 3 persons who knew who it was wouldn't tell anyone. One was a teacher and I am thankful until today that he didn't screw up my life with telling this.

Hah! I did this one at a call center job back in the day, not believing that their sysadmins would possibly leave it open.

I was wrong. I did something like "NET SEND lol" and it sent out a popup to every workstation on the network. Hundreds of them.

Good times.

Once students learnt the NET SEND command, the school was plagued with popups... IT security is an evolving thing I guess.

I had so much fun with that back in school. Our machines were running Win NT 4.0 and and the computers were labelled with a the network name. So I would check the names of the machines my friends were on, or the whole class if I was feeling bold and then create a batch file to send them hundreds of messages.

Back in 2002 or so, NET SEND was a vector for spammers to send messages over the internet as well.

There's a notifications setting in my version of Teams that allows you to turn on / off a notification when a new thread is started, per channel.

There is also the "Channel mentions" setting, allowing you to turn off @${channel_name} messages.

Our CEO gave up on slack long ago. Email is the best way to get their attention.

And to be honest Email is ok. Email is like writing a letter and it should be.

You write it, think about it send it.

In a chat you just type and send as you think and decoding that stuff in hindsight is more work.

I’d rather get one focused and well thought out mail than 20.messages of which a quarter shouldn’t even bother me.

There is no real reason why you couldn’t write Slack messages as well composed as an email. But nearly nobody does.

Slack and Teams are different. Slack has muting. Teams does not.

I'll note that we never actually acted on this plan. The idea came up when we were comparing the two. The designated Microsoft Guy at the office was pushing Teams, because it's free as in beer. However, the inability to mute or leave a channel was a big 'wtf' and I'm honestly shocked that two years later they still haven't fixed it. It was a show-stopper for us back then and still would be now.

Why wouldn't you just Hide a Team you aren't interested in? I've hidden most of the Teams in our organisation because they aren't relevant to me.

Teams has mute on channels

On individual channels it does, on an entire team it doesn't. You can mention a team itself (rather than a channel in that team) and there's no way to mute that afaik.

I guess not all CEOs know what muting a channel means.
