ultraluminous··on Wage Stagnation
"...many companies find ways to skirt corporate tax... but not all, and not really the majority (but preferentially the huge companies)"

So that's basically the case for progressive corporate tax. Everyone acknowledges that small/medium business pay the full tax rate, while large/huge corps always never anything close to it. With progressive taxation you can directly impact the latter and not the former.

ultraluminous··on Wage Stagnation
Which system is identifying the 10x engineer? What generates that gap in pay? It sorts of sounds like you are trying to fit reality into a model and not vice versa.

Thee last part of the transport is not marginal in the real world. Increased local consumption drives transport, retail, marketing, etc. etc. Real life economic modeling is not a simple supply/demand, widgets made/sold chart.
ultraluminous··on The Decline of Historical Thinking
"after Wikileaks and Snowden"

https://en.wikipedia.org/wiki/Edward_Snowden

"In 2013, Snowden was hired by an NSA contractor, Booz Allen Hamilton, after previous employment with Dell and the CIA.[1] On May 20, 2013, Snowden flew to Hong Kong after leaving his job at an NSA facility in Hawaii, and in early June he revealed thousands of classified NSA documents to journalists Glenn Greenwald, Laura Poitras, and Ewen MacAskill. Snowden came to international attention after stories based on the material appeared in The Guardian and The Washington Post. Further disclosures were made by other publications including Der Spiegel and The New York Times. "

It's fairly ironic given the context of the article and GP's comment, but it doesn't sound to me like you're forming your opinion on "the media" on a rational, factual basis.

I also suspect that you (perhaps subconsciously) exclude whichever bloggers/youtube'rs/podcasters from your personal definition of "the media"

ultraluminous··on The Decline of Historical Thinking
Well, your explanation is also fundamentally wrong. There is nothing "stupider" about learning how to arrive to a consensus and how to drive a result. The notion that learning math "makes" your thinking "smarter", but also simultaneously unable to affect a large scale change on society (cause politics are stupid!!1) is so obviously wrong I'd question the underlying assumption.

I think that's a very very narrow and specific definition of identity that most literature would disagree with. There's far more to identity then racial identity (or sexual/gender for that matter).

People incorporate anything and everything into their identity. Vegan/Crossfitter/Burner are all core identity components for many many people.

The "negotiation with society" is a function of how the individual externalizes it, and what type of reinforcement they expect to receive back.

To your example, Rachel Dolezal could maintain her self selected racial "identity" in peace and quiet if the society she was sharing it with was Tumblr and not the NAACP.

ultraluminous··on Ketamine Could Soon Be Used to Treat Suicidal Ideation
I don't have an opinion on the subject in either direction, but I was struck by this sentence -

"ketamine doc who realizes that the situation he's treating requires psychiatry for optimum outcome, recognizes they lack said experience, and makes you go to someone with that experience, is also bad?"

The "ketamine doc" you're advocating people should see to treat their persistent psychological conditions such as PTSD or Depression, has no experience or background in treating any psychiatric/psychological conditions at all (and they get credit for recognizing that!).

Given the above, what service does the "ketamine doc" provide other than selling the ketamine? Like, what difference does it make that they are a doc? The access to an IV drip? The ability to google dosage? I can do renal function work ups with my family physician.

I'm genuinely confused on what value they add beyond a street dealer (assuming identical substance quality, home tests do exist).

Which is to say, a doctor is generally understood to be something beyond a prescription pad and should actually be involved in the treatment he's supposedly providing. Also, I feel like this "treatment" model is highly likely to incentivize profit-maximizing-pill-pushing clinics rather than compassionate therapists.

ultraluminous··on Instacart paying 80 cents an hour because worker received a large tip
The point being made that you're repeatedly ignoring is that that in this scenario the staff gets the tips. Only the staff. In no point in time, whether it's individual tips or tips sharing, does the restaurant receive any part of the tips pool.
ultraluminous··on Backdoor in event-stream library dependency
All these arguments about Moral/Legal liability are just head-scathingly nonsensical to me.

Look, if you're pulling external dependencies into your project from anywhere, and you don't version pin and hash compare those dependencies every time you build, then you get ZERO security guarantees. Simple as that. You might have some "in a perfect friendly world" expectations, but no guarantees, no recourse and no one else to blame when the world does not conform.

The notion that the author of the package could/should do anything to mitigate that for you is ridiculous. Ignoring many, many plausible coercion/honest mistake scenarios, just consider that a once-reputable maintainer can over time become malicious. That's it. If you have any actual real security requirements, then I'm sorry but you don't get to say "but but but DRY!!!" and call it a day. You are responsible for what software you run in your product.

ultraluminous··on NewSQL databases fail to guarantee consistency and I blame Spanner
You can also just configure the client to point to a single db node and have an applicative monitoring based update to the db connection string upon failover. Then you're not actually dependent on your client loadbanacing logic. It's very robust and if you follow CQRS also highly available.
ultraluminous··on NewSQL databases fail to guarantee consistency and I blame Spanner
There's a substantial difference between High Availability (HA) clustering and Load Sharing (LS) clustering. In an HA cluster a production database can run on a single active node while replicating to a separate standby node. Network partitions will cause a lag in replication but will not present an external consistency issue as there's still only one active node at any time. When the partition is resolved the replication catches up and all is right with the world. Which is to say, you can scale vertically while having both reliability and availability.

Hard "distributed systems" problems in databases generally only creep up when you're trying to deploy a multi-active system.

ultraluminous··on Wharton professor says America should shorten the work day by 2 hours
What if they retired at 35 after selling their parents company or inherited real estate? Or do you think that's rare in a country that doesn't believe in inheritance taxes?
ultraluminous··on Wharton professor says America should shorten the work day by 2 hours
What does any of that have to do with anything? I don't know if you've heard of the concept but working in shifts is a thing. It even allows employers to stagger their employees' schedules such that they can acheive a 24/7, without a single employee working 24h straight! The general labor force will work it out just fine and in some cases (such as elementary schools) will actually benefit greatly from re-evaluating their current work load.

I still don't know why programmers think their profession is so fabulously unique that their office time scheduling can't even apply to any other industry.

ultraluminous··on Dark Motives and Elective Use of Brainteaser Interview Questions
The problem is that the interviewer asks for a number. If the question was phrased as "How would you go about finding out the GoogleAds B2B revenue in Italy for 2017, which tools and methods would you use", I'd totally go for that question.

The reason is that to many people (myself included) your answer above is nonsensical.

  “With ~50M people capable of clicking ads, and assuming they click one ad a day at 20cnt CPC, it would be around 3.6bn. I think my assumptions are on the high side, but order of magnitude is probably correct”  
Where did the "people capable of clicking ads" 50M estimate come from? Why one ad a day on average? Why not 0.2? Or 15? Why 20c CPC and not 0.001 euro cent? Why not 1USD?

I'm all for "first-principals based structured thinking" but asking someone to demonstrate that by generating a rudimentary formula, that won't survive any contact with reality, and populate it with almost completely random values, seems like a weird way to go about it.

ultraluminous··on Nile: decentralized, commission-free, local-economy focused Amazon alternative
There's very little to no correlation between "difficulty to get adoption/sales" and "time to market". This very article is about displacing Amazon (founded in 1994) in the ecommerce space and the very top comment is about OpenBazaar (started in 2016). You can develop your business in golang or rust or f#, but if the business idea is irrelevant or unviable then your developer economic productivity is exactly zero.
ultraluminous··on Uber shuts down self-driving trucks unit
That's one more of those "irrational exuberance" regarding the future of autonomous driving. It would never even come close to being legal if it's only better than the average driver. It will need to be better than the 95th percentile of human drivers at the very least. 48% of the human population are not going to accept a more dangerous, potentially deadlier, car ride because it's "safer on average".
ultraluminous··on BitTorrent is selling for $140M to Justin Sun and Tron
1) That assumes that what drives housing prices is residential ownership.

2) What is a "justifiable" P/E multiple? What is the justification (other than past values) for _any_ P/E ratio? What were the drivers of either the numerator or denominator?

This is to say, that macro and micro economics try to model extremely complex systems. When trying to analyze "value" it's worth considering that your mental model might not be accounting for many/most of the relevant forces.

ultraluminous··on Surviving Your 40s
I bet you'd get a similar answer from psychologists mostly because well adjusted people tend to not visit them.

You're also making a selection bias, assuming people that see a psychologist are not well adjusted. It's equally possible that only well adjusted people seek psychological consult, while others are sublimating their problems.

I don't necessarily agree with that conclusion either, but I think it's worth pointing out. Especially when discussing emotional maturity.

ultraluminous··on Tesla Looked Like the Future, Now Some Ask If It Has One
Car companies and software companies have completely different capital requirements and cash-flow constraints. Tesla is not a small software startup. They are a 40-60 billion industrial manufacturing company that is burning through its already-dwindled cash reserves while struggling with manufacturing bottlenecks. Coincidentally, said manufacturing is Tesla's sole method of generating revenue. They already have massive amounts of outstanding debt. Even before Moody's downgrade, it was not going to be easy to finance.

In general, comparing a massive company's notable operational issues to "software project delivered late" is nonsensical. If your software company's sole source of revenue is selling packaged units of your software and your company is continuously showing that it's unable to deliver those units of software in time, creating massive cash shortages - then yes, the market cap of your software company is going to suffer.

ultraluminous··on Half of the US government's financial assets are student loans
Though I agree with you that bankers should face many many more personal repercussions to engaging in improper risk management, but stabilizing banks is not about bailing the rich. The financial system holds not only main street's deposits, but also future paychecks, loan re-payments, home mortgages and, well, basically anything to do with money. When that system stops working the world stops turning, so to speak. On a certain day in 2007 Ford Motors didn't know whether they would be able to make payroll the next day, because the inter-bank money market has completely dried up. That's what bailing banks is about. Though again I agree in principal - bank shareholders, executives and board members (or partners) should've paid a much much higher personal price during all this.
ultraluminous··on Crime in New York City Plunges to a Level Not Seen Since the 1950s
I've had no trouble taking cabs and ubers to and from the bronx at least a dozen of times (and in particular the south bronx) at all hours of the night and all days of the week. A few times it was an uber pool that had other riders in it (meaning they managed to find a cab too).
ultraluminous··on India’s IT industry laid off more than 56k employees this year
The funny thing is that for all your grandstanding about developer importance and productivity and what not, the only point you successfully manage to get across is that you are an obnoxious child that no one would wish to work with.
ultraluminous··on Tax-Free Bitcoin-To-Ether Trading in US to End Under GOP Plan
The in-kind rule is not going to apply to any kind of crypto. TFA states it's now formally restricted to domestic real-estate.
ultraluminous··on What Bitcoin shows us about how money works
It does answer your question - what you're misundestanding is that "distributing money throughout the economy" is fiscal policy, not monetary policy. That's what the OP meant by "fiscal policy is necessary" and "the government dropped the ball on fiscal policy". The Federal Reserve, as a body, and monetary policy in general by extension, does not posses the tools to enact fiscal policies.

EDIT: oops didn't see OP already clarified.

ultraluminous··on IOTA: A tangled mess
What you did is point out a few real problems in our current economic reality of which inflation is one part. In no way does this say anything about how deflation solves any of them, or even leads to worse scenarios.. Think about the issues you mentioned - wage stagnation, unsustainable expectation of growth in corporate profits, systemic inequality etc. - Now ask yourself "how will removing monetary inflation and replacing it with monetary deflation affect these systemic issues, in which direction will it drive them, how and why?" If you still come out on the pro-deflation side, I'd be happy to hear your perspective.
ultraluminous··on IOTA: A tangled mess
Still in alpha but accepts real-money deposits in the tens of thousands. I think the market was unprepared for anyone being that brazen.
ultraluminous··on Etsy Announces Move to Google Cloud
Bin packing is the actual academic term for this class of problems so the intended snark in using quotes is a bit misplaced.

Furthermore, running k8s to pack containers into AWS instances that are are themselves actually full blown VMs running on a hypervisor is of course one way to do computing. It is perhaps worth considering that there are others, more direct ways that can be achieved more economically.

ultraluminous··on Coinbase Wants Wall Street to Resolve Its Bitcoin Trust Issues
What he's describing is that the overwhelmingly vast majority of people (who are supposed to replace fiat with ctypto in the future) reside on one end of the pole. The end with all the real-life, non-ideologically-constrained usability.
ultraluminous··on Coinbase Wants Wall Street to Resolve Its Bitcoin Trust Issues
"maybe you made them angry and tried to do something illegal on their site so they shut your user down."

Ahh, crypto-punk-decentralized-liberatrians never seize to amaze with the level of double-think they can achieve. How someone can hold both "the government is evil and might take your money" and "maybe you made this website angry so they didn't give you your money" at the same time is truly impressice.

ultraluminous··on Coinbase Wants Wall Street to Resolve Its Bitcoin Trust Issues
This is childish and disingenuous. Yes, counterparty party risk can only be reduced. And only mathematical constants can actually be absolute. However for practical people operating in the real world there's an infinite difference between 20% risk and 0.005% risk. Infinite.

Same with your comment about exchanges - yes the NYSE and NASDAQ can go down. Once or twice a year. For 20 minutes. Coinbase (and Gemini and GDAX and Kraken and everyone) are going down for about x5 times that in any given week. Which is not a "a small qualitative difference". It's an infinite difference.
