True... though "588/user" is more digestable than "588/current user but likely accounting for future growth which is why there is a premium - though we can't be sure that userbase does continue to grow considering the cloud of uncertainty around this deal and that the user base is largely gen z/particularly young and it is not proven that they will be sticky"

They go on to acknowledge the growth profile and valuation multiples vs competitors based off projected profits ...which is probably the more useful way to look at it -

There have been reports of investors valuing TikTok around $50 billion in the takeover bid, this is approximately 50 times its projected revenue for 2020. Many publications have compared this to SnapChat’s market capitalization which sits around $33 billion at the moment (15 times its 2020 projected revenue). While Snapchat exists within the same social media ecosystem the comparison has to account for two factors.

1) TikTok vs Snapchat’s position in the growth cycle 2) TikTok vs Snapchat’s core proposition


hmm you're right. I wonder why that is...maybe the percentage skew of content creators to consumers..I'm sure there's more to it too


“At a market cap of $755 billion (at point of writing) Facebook’s per user value is around $288. If Facebook is some leading indicator for the pinnacle of per user value for social media, then at $50 billion for the roughly 85 million American users, TikTok’s per user value would be $588.”

I think facebook would pay a hefty premium even above that; handing Microsoft a buzzing social media platform on a silver platter - with the weight of Microsoft's resources behind it. Surely Zuckerberg's nightmare manifest...and he has no real chance of trying to outbid - what with all the anti-trust press.


I would have preferred if Facebook bought TikTok. It would have been easier to run ads.


Microsoft are one of Facebook's investors, although a relatively small one.


Yeah, i guess full ownership gives them all the upside/control/ability to integrate with their other projects/ambitions.


“We’re competing against free,” Jeffrey Katzenberg says referring to the likes of youtube and social media platforms like TikTok. “We have to offer something that is meaningfully, measurably, quantifiably, creatively different. They don’t know how to do what we do, with all due respect,…”

This is what always strikes me...the knowledge that you are competing against a "new" category of entertainment but the hubris to dismiss it in one fell swoop...why wouldn't you ask "why did this cattegory crop up"; "is there something new going on here that they do better than us?"


The original google blog post being referenced - http://ai.googleblog.com/2020/05/federated-analytics-collabo...

‘A ctrl+f for ‘privacy’ brought the word up thirteen times – the subtext was very much ‘at Google, we think about privacy’. But what makes this particularly interesting is that decentralised data analysis isn’t a new concept and didn’t find its origins in privacy.'


"Mahajan describes six tools: dimensional analysis, easy cases, lumping, picture proofs, successive approximation, and reasoning by analogy. Illustrating each tool with numerous examples, he carefully separates the tool—the general principle—from the particular application so that the reader can most easily grasp the tool itself to use on problems of particular interest. Street-Fighting Mathematics grew out of a short course taught by the author at MIT"

That short course looks like its still available on edx - though it's archived - I seem to be able to access the material.

https://www.edx.org/course/street-fighting-math


The content looks quite interesting for a mathematician too—so I'm sorry that the advertising needs to be antagonising.

But even Keep the Aspidistra Flying was basically mutilated by circumstance [1] and it's still a great book. So, I'll take the insults towards mathematicians with humour and actually read some of it—I often switch between grumpy rigour to applicative speed. We all need to earn an income.

[1] https://en.wikipedia.org/wiki/Keep_the_Aspidistra_Flying#Lit...

Edit: Just to be clear, my comment on mathematicians is not on your quote, but this quote from OP's post:

> an antidote to mathematical rigor mortis


How on earth is any of the advertising antagonizing? I had to read through the course page twice to look for anything remotely resembling a criticism and came up blank.

If it is the quote you added to the bottom of your comment, my question still stands. That isn't an insult to anyone (certainly not mathematicians) but rather a comment that many people freeze up when it comes to mathematics (at least that was my interpretation).


There is a somewhat common attitude towards abstract mathematics that its preciseness is something of a bother to people and that it requires some kind of "cure".

Immanuel Kant wrote about it [1] and many engineers have a varying degree of animosity towards pure mathematics. So, in the book's description they say this:

This engaging book is an antidote to the rigor mortis brought on by too much mathematical rigor, teaching us how to guess answers without needing a proof or an exact calculation.

I don't like the advertising, or the description if you will, as it basically tries to discount rigour. One can simply say it's an addition to the usual rigour of mathematics for the sake of daily street fighting style problem solving. The way they state it, however, it sounds like they are saying that rigorous math is not necessary.

My reference to George Orwell is simply that when he wrote Keep the Aspidistra Flying his publishers made him write a lot of things he didn't want to write, and they even specified the amount of words the books needed to have (which is is somewhat understandable, but limiting still).

[1] https://en.wikipedia.org/wiki/Critique_of_Pure_Reason. However, note that this is about metaphysics and one can argue that pure mathematics is not what he was critisising and that his work doesn't directly try to disprove the use of axioms, without which mathematics cannot exist.


> How on earth is any of the advertising antagonizing?

The word "antidote" is used in the book's summary, which is defined as (via Google) "a medicine taken or given to counteract a particular poison." One could take the "poison" to be mathematical rigor, or something similar.

Perhaps this does not change your opinion, but I do not think the original comment was completely off base.


> even Keep the Aspidistra Flying was basically mutilated by circumstance

You think the British intelligentsia would react kindly to an honest portrayal of the class system?


Orwell's book's structure was dictated by the publishers, but I still love the content. My allusion was because I am wondering why the description needs to insult pure mathematics in order to promote Street Fighting Mathematics.

And similarly to Orwell's book, it seems like Street Fighting Mathematics does actually have interesting content, despite whatever the reason may be that they need an "antidote" for general mathematics.


I see what you're saying.

I think the author meant the same thing as Feynman when he described the "Greek" and "Babylonian" approaches to mathematics.

For all but a select few (pure mathematicians), the "Babylonian" approach is a lot more fun. Both approaches are clearly necessary and useful in different settings.

With the advent of systems like the Lean theorem prover, the two approaches may start to see a lot more overlap.



Edit: I'm 50:50 on whether they take the negative press hit of publishing this anyway. If they publish without name included - everyone still finds out the name of the "flippant" writer. If they don't it just concedes that their attitude was wrong to begin with. They are in a tough spot now - hard to feel sorry for them given the asympathetic position they assumed.

SlateStarCodex shutting down in direct response to the hubris/disregard of one NYT reporter hungry for a story. This parasitic appetite for airtime come-what-may approach to journalism needs to be checked. There's no reason the writer couldn't leave the real full name out of the article once requested and with legitimate concern aired by the person hes naming.

I'm glad "Scott" is taking this stance if only for the fact that it puts the onus of hard/difficult decisions back on the NYT - i.e. why despite legitimate concerns are your writers comfortable doxxing people?

The key highlight for me -

"When I expressed these fears to the reporter, he just said that me having enemies was going to be part of the story. He added that “I have enemies too”. Perhaps if he was less flippant about destroying people’s lives, he would have fewer.

(though out of respect for his concerns, I am avoiding giving his name here.)

After considering my options, I decided on the one you see now. If there’s no blog, there’s no story. Or at least the story will have to include some discussion of NYT’s strategy of doxxing random bloggers for clicks."


It's not just the New York Times either. Take a look at what happened to the NightJack blog in the UK (and in that case, it turned out that the Times had illegally hacked the blogger's email to get their information and then lied about it in court to dodge an injunction).


Wow, had not read about that!


> why despite legitimate concerns are your writers comfortable doxxing people?

This is especially important to ask when a big complaint of the NYT staff about the Tom Cotton is editorial was that it was directly endangering their safety.

Apparently the NYT does not have the same concern about other’s safety.


Or, as with much else in the woke lexicon[1], they don't use the word "safety" in the way that most people understand it.

paywalls are getting more and more effective. I remember when it used to lag and you could stop the page before the paywall kicked in!


I've heard the term seamfulness in design before without properly grasping it and it took me some time to flesh out. The basic gist as I understand it is that our experience of the "real world" is characterized by intrinsic knowledge of limitations (seams) - but knowledge thereof allows for intuitive navigation of said seams - knowing where the edges/seams are gives us a more satisfying/richer experience than running headlong into less-understood limitations where the seams have been hidden from us (ironically for our own convenience).

From the article "when we know where the seams are and how to manipulate them. The power in being able to manipulate the seams creates an elevated experience, one that emulates the ease of a seamless experience with the added power of control. Where seams help you identify how any one element interacts with the broader environment, the knowledge of ‘beautiful seams’ (source) could become invaluable to the user experience."


What a beautiful way to map out the terrain - I immediately feel inspired to use this as a starting point for hobby-research projects. Only problem is now i'm inclined to check the alternatives to "ego graphs" as a starting point for research!

I have a sneaking suspicion that SEO/keyword mapping with all the resources devoted to that space may have some tools that elaborate on this idea - though im no expert. If anyone knows of useful tools to replicate this in browser I am all ears.


You can call the autocomplete API from JS and then filter and draw the graph. Apparently you don't need an API key and it supports firing requests at the rate of typing.
