🕵️‍♂️ How Google's PageRank algorithm works

The PageRank algorithm gives each page a rating of its
importance, which is a recursively defined measure of importance, based on if important pages link to it.
It's recursive because the importance of a page refers back to the importance of other pages that link to it

Here's how it works in practice:
1⃣ We start with some pages and crawl them for links

2⃣ Each page has 1/N points (where N as the total number of pages)

3⃣ Add points to each page for the amount of links to it, divided by the number
of links emanating from the sources of these links

4⃣ If a page has no links redistribute its points equally among all the other pages

🔁 Repeat until the page points stabilise (what really happens repeating is that at each repetition there's a damping of the redistribution, but that's not easy to understand or explain 😅 but you can imagine it as a "decay" of points being redistributed)

The first area to focus on is diversity. This has become a dogma in the tech world, and despite the fact that tech is one of the most meritocratic industries in the world, there are constant efforts to promote diversity at the expense of fairness, merit and competency. Examples:

USC's Interactive Media & Games Division cancels all-star panel that included top-tier game developers who were invited to share their experiences with students. Why? Because there were no women on the

ElectronConf is a conf which chooses presenters based on blind auditions; the identity, gender, and race of the speaker is not known to the selection team. The results of that merit-based approach was an all-male panel. So they cancelled the conference.

Apple's head of diversity (a black woman) got in trouble for promoting a vision of diversity that is at odds with contemporary progressive dogma. (She left the company shortly after this

Also in the name of diversity, there is unabashed discrimination against men (especially white men) in tech, in both hiring policies and in other arenas. One such example is this, a developer workshop that specifically excluded men: https://t.co/N0SkH4hR35

I could create an entire twitter feed of things Facebook has tried to cover up since 2015. Where do you want to start, Mark and Sheryl? https://t.co/1trgupQEH9

Ok, here. Just one of the 236 mentions of Facebook in the under read but incredibly important interim report from Parliament. ht @CommonsCMS https://t.co/gfhHCrOLeU

Let’s do another, this one to Senate Intel. Question: “Were you or CEO Mark Zuckerberg aware of the hiring of Joseph Chancellor?"
Answer "Facebook has over 30,000 employees. Senior management does not participate in day-today hiring decisions."

Or to @CommonsCMS: Question: "When did Mark Zuckerberg know about Cambridge Analytica?"
Answer: "He did not become aware of allegations CA may not have deleted data about FB users obtained through Dr. Kogan's app until March of 2018, when
these issues were raised in the media."

If you prefer visuals, watch this short clip after @IanCLucas rightly expresses concern about a Facebook exec failing to disclose info.

A company as powerful as @facebook should be subject to proper scrutiny. Mike Schroepfer, its CTO, told us that the buck stops with Mark Zuckerberg on the Cambridge Analytica scandal, which is why he should come and answer our questions @DamianCollins @IanCLucas pic.twitter.com/0H4VMhtIFu

“Why are Tumblr and Facebook cracking down on sex so much? And why is Facebook in so over zealous about it? It’s all Apples fault!” Etc etc

I can explain all. It is largely the fault of a set of US laws called SESTA and FOSTA.

Butt plugs were originally sold as a miracle cure for headaches, acne, and insanity

Thread, article here and h/t: @qikipedia :
https://t.co/Ts84xnmWKJ

For a long time, medicine was pre-occupied with the question "can this be solved by putting something in the butt?"

Take, for example, tobacco smoke enemas, in which 18th Century physicians saw drowning victims and attempted to de-deadify them by blowing tobacco smoke up their rectums with a pipe.

Despite having no medical benefit whatsoever, the practice was popular, and enema kits lined the Thames like lifebelts, ready to be used as one final humiliation for somebody who was crap at swimming.

This practice ended sometime after 1800 when it became apparent that it didn't really work, given how the anus famously isn't really connected to the lungs, but doctors weren't quite finished with having a poke around in the old anus to see what happens just yet.

A quick thread on intelligence analysis in the context of cyber threat intelligence. I see a number of CTI analysts get into near analysis paralysis phases for over thinking their assessments or over obsessing about if they might be wrong. (1/x)

Consider this scenario. A CTI analyst identifies new intrusions and based on the collection available and their expertise note that the victims are all banks. Their consumer wants to know when threats specifically target banks (not just that banks are victims).

The CTI analyst has, from their collection, at this time, and based on their expertise enough to make an activity group (leveraging the Diamond Model in this example) that meet's the requirement of their consumer. So what's the problem?

The CTI analyst begins to over think it. "What if I had more collection? Would my analysis change? I really don't *know* they aren't also targeting mining companies in Australia as I don't have collection there."

The analyst knows their analysis is going to be shared. Maybe even public. "What if another team or professional intelligence firm has more collection and ends up noting that it isn't banking specific at all. Banks are victims, not targets. Will my consumer distrust me later?"

1. The major problem most startups face is marketing and the ability to carve out a niche, find and retain paying customers.

Even with a stellar developer team and a stellar product, your startup may not grow or survive without a great marketing and sales teams.

2. Start growing your audience before you’ve a product or an idea.

You should start promoting yourself and building your audience before you have a finished product or even before you have a great idea that you want to build.

3. Don’t wait to start building your audience after you’ve launched a product.

Most first-time developers actually ignore marketing.

They’re oblivious to the challenge of attracting people to take a look at something they’ve created.

4. At least until they see their first project crash and burn within hours of the launch.

There are so many times that I have seen developers spend countless hours building something, releasing it with no fanfare...

5. and only then trying to figure out how to promote it by asking marketing questions on Indie Hackers, Quora or Hacker News. Don’t make that mistake.

On 13 October Mtila as defacto overlord of the Boko Harram gang, allegedly carried out his penultimate cash-in-transit robbery. Sources say he sustained a head wound in a shootout with security guards. Some friends believe he was killed by a fellow

He died two days later, on 15 October, after allegedly being in a coma for more than a day. His funeral was a spectacle, held on Nyanga Sports fields on 24 October and attended by hundreds of people. Sources say it was made possible by Paarl businessman Lukhanyo "Spur" Mangena.

1) My Stan Lee story happened when I was in 5th grade. I was visiting NYC with my Dad and had read the address for Marvel in the comics I read constantly. I begged my Dad to take me and to his credit he did. And guess what? It was just an office.

2) We were down in the lobby and I was kind of crushed. I don’t know what I expected, The Thing and the Yancy Street Gang to be sitting around smoking cigars? Anyway, my Dad was taking a beat to figure where we were going next and a guy came up to us.

3) He was wearing a white shirt and tie and said to Dad “Is he disappointed because. The Marvel offices were just offices?” My Dad said yes and then the guy who had gray around his temples and a mustache said “hold on a second” and opened one of those office mailboxes with a key.

4) He then handed me a thick stack of EVERY SINGLE MARVEL COMIC COMING OUT THE NEXT MONTH. “Here you go. Keep reading Marvel comics” he said and then walked off. I left in a daze and about 15 minutes later it hit me “Gray around the temples, mustache... That was Stan Lee!”

5) Later when I wrote on the Ant Man movie I told Kevin Feige the story, the year, look of the guy etc and Kevin said “That’s exactly the kind of thing Stan would do and he would have been there then. That was him.” Rest In Peace Stan Lee and thank you for the comics.
