genericpseudo··on Ask HN: How would you turn Twitter around?
There is no such thing as "just words". That's a position only sustainable from privilege.

"2 years after a jury found that Ellen Pao"

... found that Ellen Pao could not prove her case on the balance of probabilities. That's not the same thing as you just said.

genericpseudo··on Cloudflare Reverse Proxies Are Dumping Uninitialized Memory
Which means any user who has used any service which uses CloudFlare, right? At least in theory.
genericpseudo··on Finding the most depressing Radiohead song with R
Apparently the second happiest song on OK Computer is "Fitter Happier". (A pig / in a cage / on antibiotics.)

So much of Radiohead's bleakness is in their use of irony.

genericpseudo··on Finding the most depressing Radiohead song with R
Cute! But, well, this is obviously bullshit:

> the cheeriest, 15 Step

The title line: "fifteen steps and then a sheer drop". A song which makes explicit references to, well, execution by hanging is...

(And "you used to be alright; what happened?" is a repeated motif.)

genericpseudo··on Uber Investigating Sexual Harassment Claims by Ex-Employee
Yes, exactly. Nothing should be off the table if this is nearly as wide-ranging as alleged, up to and including Travis Kalanick's termination for cause as CEO.
genericpseudo··on Reflecting on one very, very strange year at Uber
There is very little good that can happen when a company serves or provides mind-altering drugs to its employees. That includes alcohol.

If your culture is one where that's necessary then the entire management chain should be fired.

genericpseudo··on Wall Street Is Giving Up On Twitter
News is not monetizable because real, actual news is depressing and no-one wants to run ads for chocolate next to pictures of starving kids.

It's always been the fluff which drew the ads; the lifestyle and sports content.

genericpseudo··on Wall Street Is Giving Up On Twitter
Local ad networks masquerading as news organizations. Record labels and newspapers have a lot in common; they were global logistics companies first (the core competence of Atlantic was shipping highly-processed petrochemical discs around the world) and media companies not really at all.

What newspapers had was a lock on the business now owned by Craigslist, with the transport and fulfillment network (newsagents and delivery vans!) being the key asset. Once that went away they were no longer businesses.

They didn't see it that way, but that's because their core business was so good they could afford to delude themselves - it didn't matter that they didn't know what they were really doing, the business model was that powerful. Google is remarkably similar in many ways.

That came with local loop unbundling, neutrality rules, and two competition authorities (local and pan-European) with real teeth.

This is a bad thing how? Serious question. The US would be a much happier and healthier place if it were more like the EU.

genericpseudo··on Ask HN: Will we ever have affordable and attractive urban housing for all?
Energy efficiency. Rural living cannot be made energy-efficient and as such is, ironically enough, catastrophically environmentally unfriendly.
genericpseudo··on Grumpy: Go running Python
By volume numpy is mostly assembler written to the Fortran ABI (it's a LAPACK/BLAS-etc wrapper).
genericpseudo··on Opendoor, a startup worth emulating
It strikes me that maybe the best analogy for your financial model is old-school 19th-century shipping (as in; the reason London is London, more or less)? You're taking a trading risk on illiquid goods but your holding times are reasonably short (certainly under a year, presumably much less than that in hot markets).

What a cool business. Congratulations.

genericpseudo··on Opendoor, a startup worth emulating
They're real-estate market-makers. Market-making is one of the most reliable strategies for making money in financial markets.

This is really smart as long as you can pull it off (and you have the network to get the capital and debt together to get it off the ground).

genericpseudo··on Major advancements in Deep Learning in 2016
This is impossible to respond to without engaging in political analysis (particularly around equality of opportunity), but the reason that a small number of people do the research is largely that it's both expensive and requires a lot of highly specialized knowledge, which typically implies extensive postgraduate education.

Credentials can be abused, sure, and they're a shorthand for a more complex set of concepts, but they are on the whole a very good thing.

The thing is, anything past abstract algebra is (at some level) politics.
genericpseudo··on Tell HN: Political Detox Week – No politics on HN for one week
> the world is fundamentally and inescapably political

Thank you for saying this.

It feels like what we're seeing here from HN leadership is denial - or abdication – of moral responsibility. That's a choice you can make, and it's known to be an argument going on within Facebook right now. It doesn't impress me much, but in all honesty, HN doesn't; this place has real problems with sexism and racism.

Speaking personally, I guess it means I'm unlikely to ever apply to YC, because I weigh these moral – call it social justice, that's fine with me – considerations pretty highly in choosing who I work with. Other people will find different personal calculuses here. Many YC founders are my friends and they speak highly of the people involved; this just happens to be over my personal line.

Nevertheless, I'm still just... disappointed.

> Even if you don't come away agreeing with the conclusions of Marxist economists, etc., understanding it is worth the time it takes

Yes! It's a useful lens – just as Hayek is. No-one has a monopoly on absolute truth in the social sciences, so understanding (and empathizing with) all the framing narratives, most all of which have some kind of a point, is crucial to being able to navigate these kinds of discussion.)

Understanding Marxist (and Hayekian) thought has been very helpful to me in framing my own politics – which, ironically enough, wind up being moderate market/social liberalism in the European tradition.

> those with the means of production have hoarded the benefits

And, behold, we see someone rediscovering the central tenet of Marxist economic theory.

(Entirely serious; not an insult. HN readers could really do with a more balanced economic diet – reading more Marxist theory and less Chicago School...)

genericpseudo··on Exact mapping between Variational Renormalization Group and Deep Learning (2014)
Nice to know I've not completely lost my physical intuition. (Used to study solid-solid phase transitions.)
genericpseudo··on Exact mapping between Variational Renormalization Group and Deep Learning (2014)
This is very much not my area of physics (I worked in condensed matter), but from what I know I'm not seeing anything which looks outrageously implausible.

I think the intuition is something like this, and I'm going to be really informal here so please indulge me while I have a go at the pop-science version (and experts, please correct me!)

One of the ways deep learning is useful, compared to other feature extraction schemes, is that (in most formulations) it's a multi-scale method (it learns features at various length scales from very short to very long, specifically as you ascend/descend layers in the network).

The renormalization group is a mathematical framework for reasoning about how physics changes between length scales. Very informally, the hardest unsolved problem in physics is building a single theory which works for both the very short and the very big – very big problems (astrophysics) have an effective theory in the form of general relativity, very very short length scales have effective theory in the form of quantum field theory (basically all of modern particle physics), and the rest of physics (e.g. quantum mechanics, which from a purely theoretical perspective just is the entirety of chemistry and materials science...) is likewise somewhere in between on the great cosmic measuring stick.

So far so Powers of Ten, right?

The challenge is building a mathematical structure for transforming between these length scales in such a way as to have a coherent single theory which works for all of them. This is what people mean when they talk about "unification" in physics. The best mathematical framework we have for that thus far is the renormalization group.

So this paper – which I have no more than skimmed – purports to show that these two mathematical structures are (in some deep sense) more or less the same shape, which would make sense given that the problems they are solving are the same kind of shape (making sense of something at a range of length scales).

So it could be wrong, but it's not obviously misguided. Is it useful? In terms of practical machine learning applications right now, probably not (and ditto, but more strongly, in terms of theoretical physics). But if it means a bunch of mathematical techniques worked out in one domain can be ported over to the other (in practice, from particle physics to analyzing deep neural networks), that'd be useful!

It's not so bad, actually; you have to file FBAR, which will take you a couple of hours, but that's about it.

Oh, England and France are entirely about the narcissism of small differences. (Also England and Scotland, hence the Auld Alliance of Scotland and France.)

Life's too short to work with pollutors.

And yes; I want working with Thiel to be a large net economic loss, because I believe that's the language he understands. This is the only effective tool I have to try and do that. It's nowhere near enough, but it's what I've got.
