Checking your units is a basic sanity check that we teach students. But as we advance, physicists throw away that wisdom. Theorists especially have an annoying habit of doing this, because all the repetitions of "c", "hbar" etc "k_B" etc clutter up their equations.

But I preffer to keep that stuff in, even when doing pretty abstract stuff. Essentially because I wanted the type annotations. For example my favorite convention for the Minkowski metric is:

[c^2 0 0 0]
[ 0 -1 0 0]
[ 0 0 -1 0]
[ 0 0 0 -1]

That way your vectors are just $(t, x, y, z)$, where $t$ has units of time and the rest of space. Your covectors do come out oddly as $(c^2t, -x, -y, -z)$, but that's what makes them covectors.
> Oh, and forget doing your own maintenance or buying parts to do so. No such luck - Unlike a real car manufacturer, Tesla won't sell them to you.

That might be a legitimate criticism of an economy priced car targeted at a very cost sensitive market, but a Tesla Model S is not that car.

I doubt a significant fraction of owners of recent model year $100k+ luxury cars are doing their own maintenance, or there are enough who want this to justify the business case for owner self maintainability.

I believe that a market for a cheap owner repairable EV exists or eventually will, though. Perhaps Tesla will offer something in that segment but if they don't other manufacturers will.

I'm actually very interested in CRDTs and related approaches, and I've been exploring active research directions in the area, but I'm not sure they share many usage patterns with data stores like Postgres, which support very general access and update semantics.

The primary restriction for anything involving CRDTs is that no operation can "take back" something added by a previous operation, so the data in question can only evolve monotonically. It's great when you can get away with it, but it's unclear how often you can actually get away with it.
Thanks!

It was my first domain name I ever bought back in 2001.

Started a t-shirt business to pay for my best friend to join our frisbee team on spring break after he had been bankrupt by medical bills beating cancer. It took off a bit and paid my rent in grad school (Madison).

At some point I got scammed by Nigerians and had to shut it down due to the cash flow screwing up production.

Strangely, while at Madison it also lead to inspiring Elliot Bisnow, and me helping him launch Summit.co (along with other crazy tales like a spin off t-shirt co locking horns with a fledgling TheFacebook).

Years later I set up a printful shop with the designs as a legacy memorial, though we rarely sell many shirts now.

But I think if you play ultimate frisbee, @175g.com is the best email address domain you could want!

I'm just reading your blog now. The first article has this statement in it:

>The fundamentals are broken and whatever happens to the price in the short term, the long term trend should probably be downwards. I will no longer be taking part in Bitcoin development and have sold all my coins.

That was written back in January 2016. I think you were wrong about that.
It's not a dupe of that story, the author is describing her own case. I didn't have enough characters to include the entire title. She does summarize the think tank story in the first three paragraphs, but her own reporting comes after that.
The ideal state of charge for a lithium battery is 50%. So charging between 20% and 80% would significantly lengthen battery life. If you wanted to completely optimize for low battery degradation you'd charge between like 49% and 51% and only have a few minutes of usage, but that kind of defeats the point of keeping a lot of battery capacity.

One of the biggest reasons why GitHub (for example) uses a separate subdomain is so that a persistent XSS exploit on their UGC domain cannot access HTTPOnly cookies or other information from their real domain. Impersonation is a bigger problem for a government, but it's also a security measure against how broken the current security model for things like cookies is.
Then you lose the update mechanism because that's tied to the play store and not the OS. One of the more subtle ways that google maintains hegemony over android.

I don't care much for Apple but I agree they're the best of the lot when the lot consists of companies like Facebook, and Google.

My beef with Apple is their holier-than-thou attitude when it comes to Apps on their store. They didn't allow Gab.

In the past they've kicked out political parody apps. Finally they allow hate speech masquerading as religion while banning criticism of the same.

None of them are a monopoly. There are alternative search engines, email providers, and phone OSs. There are alternative social media platforms and alternative online and physical marketplaces. There is no natural factor about them that tends toward a monopoly (like limited wireless spectrum or need for public right of way).
US Government doesn't have the right to selectively punish people or their companies just because it's politically popular right now.

Beyond that, there is really nothing wrong with monopolies in general, only if they became monopolies via government corruption like, ma bell, wired ISPs, alcohol, and possibly big banks, big defense, and big pharma. Google built search from nothing and remains by far the best offering. Facebook spends exorbitant sums to aquihire its rivals and preserve its market share. Amazon has always reinvested and certainly has made shopping and web hosting less expensive for me.

While I agree they have too much of our personal information and influence with elected officials, the solution isnt more regulation which would crown a loser and make lobbying an even better investment. Should we also break up Bing, Twitter, and EBay?

Those are reasons not to automate, but they're not arguments against automation. If there is too much automation in an economy (across industries) then there are fewer people available to buy products that are being made. From a Marxian point of view, purchase of automation machinery is part of the cycle of capital crises, and contributes to the tendency for the rate of profit to fall for the employer of automation, because he extracts less surplus value, as machinery embodies dead labour and only has the running cost of 'replenishing' this labour by replacement of its parts or general maintenace of it, these costs coming out of the surplus value extracted anyway.

There's a wonderful little essay by Ernest Mandel on the effects of automation on the amount of wage labour employed in his own time (the 80s), why this occurs, and how capitalism deals with automation versus how a Socialist mode of production might do so: https://www.marxists.org/archive/mandel/1985/xx/future.html

Edit: a relevant little quote follows.

"Japanese socialists [7] have tried to study the effects of new technologies especially on the automobile industry. Also stressing qualitative aspects of the changes (loss of skills, increase in accidents, emergence of new layers of workers and of skills etc.), the authors find a reduction of shop floor workers of around 10% at the most highly ‘robotised’ automobile plant in Japan, Nissan’s Myrayama Plant, between September 1974 and January 1982, accompanied however, by small increases in white-collar personnel. Even the Japanese ‘company unions’ seem worried by these developments, ‘life-long employment’ still the rule in Japan notwithstanding (Japan Economic Journal, February 21, 1984)."
No doubt some people can do that. But the original quote is comparing broadband to the railroads. The railroads (and mining) supported a broad economy with various roles for lots of different kinds of people. I have a hard time believing that broadband is going to have the same effect through remote sales and database admin jobs.

>>customer obsession is #1.

Their straight-up customer support is outsourced, but works well enough from a scaling perspective. Given how large the company is, I also agree that they get an A- at worst.

But more importantly, their domination of logistics is a truly impressive feat. There is a constant flow of articles on HN, reddit, and everywhere else about how Amazon's prices are no longer the cheapest and how they are a monopoly and how you should shop around and JET.com and blah blah.

No one cares that it's not the cheapest. It's almost like people forgot that 10 years ago, buying things online and dealing with horrendous shipping was a nightmare, complete pain in the ass, and took forever. Amazon decided to grab USPS by the neck and make them work Sundays (how do you get a government institution to do that?!) and develop their own logistics network to deliver many items same-day, or even within an hour. It's truly an amazing feat that puts customers' minds at ease; there is no wonder why there is such loyalty to Amazon.

Solving that customer problem is like an act of God to the masses.

It's definitely related, but it's not a duplicate.

This article is written by Kashmir Hill, describing how a story she wrote in Forbes six years ago that was unfavorable to Google was suppressed.

The article you linked to is by Barry Lynn writing in the Washington Post about how he was forced out of the New America think tank in June of this year for writing in support of the European Union fining Google for antitrust violations.

I'm glad that gizmodo is covering free speech (I believe they're left leaning in general). Just make sure to verify all the claims made in any politically biased publication.

The bigger issue is that people have this mistaken impression that think-tanks are independent academic institutions.

They're not.

They're private organizations that corporations go to and pay them to write a research paper that aligns with their corporate interests. That's what think-tanks are. That's their business model. They're not academia.

Google is this think-tank's customer. And when it fired the guy, the think-tank is basically making themselves more customer-friendly. Calling them "evil" is like calling a customer "evil".
So this all hinges on a deleted story being removed from search results too quickly? Google crawls some sites (especially high-traffic news sites like Forbes) more frequently than others. And why should a deleted article still show up in search results? It's entirely plausible to me that there was no manual intervention.

Perhaps it's questionable that Google wanted the article taken down in the first place. It's hard to know the legitimacy of that request without knowing the specifics of any NDAs applicable to the meeting. But at the least, the article would damage the relationship between those two groups at those two companies.
What can I say? My actual experience differs from yours. I have no doubt that there are many fly-by-night operations out there that don't know how to configure their networks properly, but I know of at least two examples that seem to do just fine. There are no significant problems with latency or jitter or lost packets. You seem to take strong issue with data caps. They are unfortunate, but I don't really see any way to avoid that in a wireless environment. Heck, even in a wired environment, I suspect you'll find some limits hidden in the fine print. Even then,the data limit appears to be more of an issue of willingness to pay than any fundamental limitations of the technology: i.e. if customers pay for packages with higher caps, the ISP will have the income to maintain the network to support the higher caps.

Energy costs are a tiny fraction of launch costs. If rocket fuel could be had for free, it wouldn't noticeably change overall costs.
Thank you. I was just dismissing that last sentence without much consideration. I see your point.
If this account is even remotely accurate, this goes well beyond "quashing ideas it doesn't like" and into chilling effects on reporting public-interest information. The New America affair was ostensibly about Lynn's opinion of an event that was already public knowledge (and, by extension, the opinionated policy stance of the organization). In this case Google was seemingly trying to keep questionable marketing tactics out of the public eye altogether.
She says it was her own decision to pull the story down. But yes, clearly they were leaning on her.

Seeing type errors logged is only "good" if they are catching actual bugs. A large amount of Scala type errors aren't bugs I would have had in Python; they're hoops I wouldn't have needed to jump through like worrying about whether a parameter should be a "Long" or an "Int".

> Apple has time and time again demonstrated to be reasonably ethical

Along with the things others have mentioned, their campaigning against right to repair seems pretty unethical to me.
Hi, I work on the LogDevice team at Facebook.

Within an epoch, the sequencer is a single process on a single machine and gives out LSNs sequentially. When a sequencer dies, and a new one is started, its first job is to fix up the end of the last epoch. If it can't find any copies of a given record, it inserts a "hole plug," to store the fact that the record is lost. So, except for hole plugs (which should be very rare), the only gaps are between epochs as you say.

Suppose you have 10 LogDevice servers, and you store 3 copies of every record. Then the client will have connections to all 10 machines, and each machine will push whatever records it has to the client. Crucially, the servers always push records in order. So if a client gets record N from machine 7, then gets record N+2, it can be sure that machine 7 doesn't have a copy of record N+1.

Once you've got record N+2 or higher from at least 8 machines, without getting record N+1 from any of them, you can be sure that at least one copy of the record has been lost. If those 8 servers have complete information, you can report to the user that the record has been lost.

Sometimes other people know more about something than I can afford to figure out by myself, and listening to what they have to say can be useful.
Controlling the information that we're exposed to is incredibly powerful. If you tweak the results - positively or negatively - it's easy to nudge, influence, and eventually convince people of what you want.

As I've cited often:

> "We predicted that our manipulation would produce a very small effect, if any, but that’s not what we found. On average, we were able to shift the proportion of people favouring any given candidate by more than 20 per cent overall and more than 60 per cent in some demographic groups. Even more disturbing, 99.5 per cent of our participants showed no awareness that they were viewing biased search rankings – in other words, that they were being manipulated."

Apple's objection isn't to paying for bandwidth, it's to fast lanes:

"Paid fast lanes could replace today’s content-neutral transmission of internet traffic with differential treatment of content based on an online provider’s ability or willingness to pay."

It's not questionable marketing tactics they were trying to keep out of the public eye, it was the suggestion that they're abusing their dominance in search to enter a new market (in this case social networks).
I'm on the LogDevice team at Facebook. The "copy set" is the subset of server machines that a given record is stored on. For example, if you have a cluster with 10 machines numbered 0 through 9, then the copy set for record 1 might be 3, 6, 8; for record 2 might be 0, 2, 5, etc. Copy set can change with each record. The node set (the list of 10 machines) is fixed for the length of an epoch.

I think the best sport for that is actually basketball. NBA contracts are far more lucrative, and NBA rosters far smaller, and injuries are far less common, which makes NBA players more athletic and talented than NFL players by far.

Consider also the fact that many great NBA players were also standout high school football players who gave it up for basketball. You don't really see that happening the other way. NBA players (and soccer players) also have to exercise more continual decision making skills, since there's no stoppage between plays or radios for the coach to signal plays.
