Turla’s watering hole campaign: An updated Firefox extension abusing Instagram
Pretty crazy.
The extension will look at each photo’s comment and will compute a custom hash value. If the hash matches 183, it will then run this regular expression on the comment in order to obtain the path of the bit.ly URL:
(?:\\u200d(?:#|@)(\\w)

Looking at the photo’s comments, there was only one for which the hash matches 183. This comment was posted on February 6, while the original photo was posted in early January. Taking the comment and running it through the regex, you get the following bit.ly URL: bit.ly/2kdhuHX

Looking a bit more closely at the regular expression, we see it is looking for either @|# or the Unicode character \200d. This character is actually a non-printable character called ‘Zero Width Joiner’, normally used to separate emojis. Pasting the actual comment or looking at its source, you can see that this character precedes each character that makes the path of the bit.ly URL

Exclusive: The Leaked Fyre Festival Pitch Deck Is Beyond Parody | Vanity Fair
This is the worst future ever.
As the pitch deck claims, within the first 48 hours of the social-media blitz, the Fyre Starters had reached “300 million social impressions”—impressions being the kind of dumb synonym one uses instead of the word “people,” in the same way someone at a bar tries to sound smart by saying he is “inebriated” instead of “drunk.” (And to be fair, an impression isn’t even a sentient person. It’s essentially reaching a person when they aren’t paying attention.) To pull off the 300 million impressions, McFarland and Ja Rule partnered with a P.R. agency, a creative agency, and Elliot Tebele, a once-random nobody who has created a social-media empire by siphoning other people’s jokes into the Instagram account @FuckJerry.

One of the biggest deceits of the entire media campaign was that almost all of the 400 influencers who shared the promotional videos and photos never noted they were actually advertising something for someone else, which the Federal Trade Commission requires. This kind of advertising has been going on for years, and while the F.T.C. has threatened to crack down on online celebrities and influencers deceitfully failing to disclose that they are paid to post sponsorships, so far those threats have been completely ignored.

Instagram: Making the Switch to Cassandra from Redis, a 75% 'Insta' Savings
shifting data out of RAM and onto SSDs -- unsurprisingly, big savings.
a 12 node cluster of EC2 hi1.4xlarge instances; we store around 1.2TB of data across this cluster. At peak, we're doing around 20,000 writes per second to that specific cluster and around 15,000 reads per second. We've been really impressed with how well Cassandra has been able to drop into that role.
