Explanation of differences between corvettes, frigates, destroyers and cruisers (as recorded from a Quora discussion):

1. (THREAD) So, it seems like the deplatforming debate is once again kicking off, so I thought I would introduce some of the earlier work that was done in this area back when ISIS was buck wild on social media. What have we learned over the last six years might be useful today:

2. One of the earliest studies that discussed the impact of suspensions of ISIS accounts was @intelwire and Morgan's piece: The ISIS Twitter Consensus.

They found that suspensions did have an impact on replies and retweets and overall dissemination.

3. After suspensions, the die-hard supporters dedicated themselves to creating new accounts, but others whittled away: “it appears the pace of account creation has lagged behind the pace of suspensions”

4. On the specific question of how suspensions impact the Twitter network, see this piece by @intelwire and @IntelGirl111, which explores how suspensions impact these groups, including major disruptions to dissemination and decline in follower count:

5. Another study by @Aud_Alexander similarly found that ISIS supporters were finding it hard to “gain traction” after Twitter took a harder stance on the group.

In my quest to write a fast IPv4+6 parser, I have written a slow-but-I-think-correct parser, to use as a base of comparison.

In doing so, I have discovered more cursed IP address representations that I was previously unaware of.

A thread!

We start out simple, with IPv4 and IPv6 in what I'll call their "canonical form":

192.168.0.1
1:2:3:4:5:6:7:8

Various specs call these "dotted quad", dot-separated fields each representing 1 byte; and "colon-hex", colon-separated fields each representing 2 bytes.

The first bits of complexity come from IPv6. In canonical form, common addresses would end up with long runs of zeros in the middle. So, "::" allows you to elide 1 or more 16-bit blocks of zeros:

1:2::3:4 means 1:2:0:0:0:0:3:4

Next up, for cursed historical reasons, IPv6 permits you to write the final 32 bits of the address in dotted quad form. Effectively, you can splat an IPv4 address onto the end of IPv6 addresses!

1:2:3:4:5:6:77.77.88.88 means 1:2:3:4:5:6:7777:8888

And of course, you can combine the two!

fe80::1.2.3.4 means fe80:0:0:0:0:0:102:304

@curaffairs The author doesn't know enough about search to have written that article and the reason he's having those problems is AI algos like Rank Brain and Google's attempts to use natural language processing nothing to do with SEOs.

1/x

YMYL is not evaluated at the site level, but the query level.

Again this is on Google, not SEOs because they want to surface better sites.

And those devaluations are part of Core Updates which SEOs like me recover sites from.

2/

Featured Snippets are not optimized for - you can use certain HTML to be pulled in one but there is no definite use case where Featured Snippets are shown or that your site's will show for it. Also doesn't always come from the #1 result.

& that's Google not the SEO.

3/

Also there are many times when an SEO doesn't want their site in the Featured Snippet cuz it doesn't result in a click to the website. But we have no control over what Google pulls as Feature Snippets except to put in a meta tag to exclude us from them

4/

And Neil Patel is not an SEO. Most senior level SEOs see him as nothing more than a scammer because reportedly he's ripped them off by stealing their content and articles and passing them off as his.
