1. Less spam.<br>
2. Private DMs, just email the person.<br>
3. Long form.<br>
4. No social media plagues of likes, dislikes, ratios.<br>
5. Identity verification via gpg<br>
<br>
Not necessarily a comprehensive list, and there’s definitely something to be said for twitter’s bitesized content making it easy to consume a stream of consciousness from around the world, both positive, and negative.<br>
<br>
On topic, if anyone has experience using libfabric with OpenMPI I’d be interested to hear. I need to do a little more poking, but trying to get RoCE on anything other than Mellanox still seems to be painful.<br>
