As long as the as the "abstract constructs" themselves weren't much more complicated than the current real-world economic concepts, it would only be slightly more difficult. You would need some background reading, but not any more than skimming relevant Wikipedia articles for definitions. And in that case, you'd have every reason to be pissed at economists who don't present their findings in much simpler and obvious way.

If, however, the abstract constructs were much more complicated then the current economic concepts, and if you were trying to solve problems on much higher level of abstraction than economists currently are, then it would just be mathematics, and indeed it would be more difficult.

I, personally, cannot imagine how you could rewrite Akerlof's paper to be as hard to understand as Atiyah's. I can, with great difficulty, follow Atiyah's paper only because I spent literally _years_ learning the necessary background material. I am completely unable to relay my understanding to someone who hasn't spent years doing the same. I wish I was -- I'd revolutionize algebraic geometry then, just like Alexander Grothendieck revolutionized it around when the Atiyah's paper was written. On the other hand, if someone rewrote Akerlof's paper in an intentionally obscure way, you could easily rewrite it back in a clear way, once you spend the effort to understand the obscure version yourself.

The thing is: in the long run, yes; in the short run, Waymo is manufacturing its own chipsets that it has a patent on. It's not using COTS kit for on-board processing, which gives it a significant technical advantage that will be hard for competitors to match.
I often think about the Witness Protection Program and how much harder it must be to be a part of it in the age of social media and new forms of instant communication. While it's hard enough to cut off ties with family and friends, etc., it must be much worse when there are so many ways to keep in touch with people. Worse, I can't imagine someone in the program would be able to have any kind of online presence. It would be too easy to leak details about yourself.

Sense 2 is common and not at all new but has been frequently criticized as an illogical misuse. It is pure hyperbole intended to gain emphasis, but it often appears in contexts where no additional emphasis is necessary.

Well, if you are going to force me to actually think about it rather than just fire off one liner advice on the internet to one of the most successful companies in the history of the world like I actually have any idea what I'm talking about:

I would try it with some higher-end stuff first, relying on the same distribution system and then slowly moving the most popular online purchases over to it to ensure that the "walmart" feel is eliminated. I'd focus on a high end "organic produce" feel to the website.

Target did something similar with it's "Up&Up" store brand stuff, and they have done it with clothing lines as well.

The hard part is Walmart admitting to itself that it's image, particularly on the wealthy, online-shopping coasts, is not universally good, and slapping a wally-world star on things is going to drive a lot of good customers away.
Did the same thing, used an old Dell Optiplex Mini tower, put some WD Reds inside -> Now I have a nice NAS with Plex.

> > But you don't need an atomic clock to get Spanner's guarantees.

This comment continues "...but GPS clock-sources will do just fine for Spanner's 6ms quantum". Providing Spanner's guarantees with reasonable performance requires specialized hardware, but there are more options for that specialized hardware than just atomic clocks.

Note that Spanner itself uses both atomic and GPS time sources according to Google's publications; when we talk about "atomic clocks" we're usually talking about the entire category of specialized time-keeping hardware instead of distinguishing atomic clocks from GPS clocks.

> I always hear this from CockroachDB folks and fans, but no details. What are the downsides?

As we describe in our blog post (https://www.cockroachlabs.com/blog/living-without-atomic-clo...), CockroachDB on commodity hardware provides a slightly weaker consistency model than Spanner (serializable instead of linearizable), and latency is sometimes higher as we need to account for the larger clock offsets in certain situations.

If you do have a high-quality time source available, we have an experimental option to use a Spanner-like linearizable mode.
Just the number I found, what do you say it is? 71% of the world lives on less than $10 a day, average globally yearly income is less than $1,500. Even the worst off Americans are extremely well off comparatively to the majority of the world is my point.

Well, I was able to recover from damaging my RPi B+ by simply slotting its microSD card into a brand new RPi2 and everything ran, which is completely astonishing as they are not identical.
There is an important difference. "Flying cars" was always a media and popular culture thing - the vast majority of experts thought they were a long way off, if ever. This is not true of self driving cars.

Self driving cars are also a pop culture thing - and the most aggressive deadlines and comprehensive deployments predictions are unlikely.

One thing to consider: before Stack Overflow (and the internet in general), it was harder to learn about fringe languages but it was also therefore harder for fringe languages to get the kind of business toe-hold that made learning them a financially-valuable expenditure of time.

Windows 10 ‘Kill Switch’ Can Identify and Block All Illegal Downloads
The lack of visibility is partially because apps can store files in various locations.

Outside of the app binaries and such you have their core data, stuff that gets generated or downloaded on first run.

Besides that you have a cache directory pr app that is housed outside of the tree location of the binaries and main data.

More recent Android versions have introduced yet more complications on this via the storage access framework, by providing APIs that give apps limited RW access to "external" storage areas without having to request the related permission.

And that's without going into the whole history of just what "external" means when dealing with Android file storage.

Waymo is going to be able to inspect Uber's LIDAR and get additional expedited discovery:

"Waymo is hereby granted further expedited discovery in aid of possible further provisional relief. Subject to the protective order, and upon reasonable notice, Waymo’s counsel and one expert may inspect any and all aspects of defendants’ ongoing work involving LiDAR — including, without limitation,schematics, work orders, source code, notes, and emails — whether or not said work resulted in any prototype or device. Withrespect to its trade secret misappropriation claims only, Waymo may take seven further depositions on seven calendar days notice, may propound 28 reasonably narrow document requests for which the response time is reduced to 14 calendar days, and may propound 28 reasonably narrow interrogatories for which theresponse time is also reduced to 14 calendar days. If Waymo moves for further provisional relief before trial, then all its declarants in support of such motion must sit for depositions on an expedited basis. Otherwise, defendants may take only normal, unexpedited discovery. After Waymo has exhausted its expedited discovery, it may continue with normal discovery."
First and foremost: This is really cool, and thank you for sharing! (It's also the first explanation of the terms in the matrix equation for SVD that I've happened across that has really clocked for me: much appreciated.)

Here's my worry, speaking as someone who knows physics but not all that much audio processing. I feel like this approach will inevitably put a whole lot of (unhelpful!) emphasis on the detailed phase information of the various sounds. The near-perfect cancellation of the average track illustrates this: two loops of the exact same bass drum beat offset by a fraction of a second will be treated as orthogonal or even opposite by this algorithm, but they're essentially identical as perceived by the listener.

Conceptually, I imagine what you'd want is some way of encoding the various loops whose average came out sounding like a real average, rather than as nearly silent due to phase cancellation. My first instinct is to say "take the FFT of each loop first, and then run your PCA on that". Maybe that's not the right answer: like I said, I'm not an audio processing expert. But I suspect that right now your analysis is spending a huge fraction of its effort effectively trying to get the first drum beat to happen at precisely the right fraction of a second, and separately to get the second drum beat to happen at precisely the right fraction of a second, and separately the third, and the fourth, and so on. And heaven help you if the different loops' bass drums are tuned to marginally different notes.

Edit: Only after writing this did it sink in that the top overall comment's remarks (by "highd") about earlier dimensional reduction were getting at the same issue. I'll leave this here, just in case the different framing is useful.

I've started to think we might have the causality reversed here: government is inefficient not because it's 'the government', it's inefficient because the problems it concerns itself with don't have efficient market-based solutions (e.g. poverty alleviation, national defence etc.).

If you think about government delivered services as simply a provider operating in a market for that service, you'll find a startling large proportion of them are natural monopoly markets, or markets that produce public goods (non-rivalrous and non-excludable e.g. national defence). Would a private monopolist be more efficient in these situations, simply because they are not 'the government'?

America is not a democratic nation (that's like saying all bugs were written by the programmer so all bugs are features). Democracy was tried in Greece and even Romans didn't use it.

The sheer fact that we have a constitution to limit the powers of the democratically elected govt means that we applied a patch on democracy from beginning itself.

If relying on the goodness of the govt were a feature, then we wouldn't need a constitution (which technically isn't even a patch but rather a unit test supplied with the system, which in itself can be modified).
"The basic problem of our world is that it is ruled by 20-sometings that loath working on "old" tech. The epitome of this is the FOSS world that goes through a wrenching rewrite churn every 5 years or so as new heads take over "old" projects."

Disagree thoroughly. The reason why people push shit through the security-updates channel is because of money and structural pressure from management to ensure adoption of the company's new $THING.
This ruling was actually relatively good news for Uber, it could have been worse. It's only a partial preliminary injunction, they can still continue working on self-driving technology.
I've observed a growth in Lyft drivers in Dallas, too.

When I first started using Lyft in 2014, there were many times when attempting to request a ride would return an error saying there are no nearby drivers, especially during rush hour (trying to get a ride at 8am was simply a no-go), and it wasn't uncommon for the nearest driver to be 20+ minutes away at various times of day. I actually heard a lot of drivers complain to me about how Lyft sends them pings from people ridiculously far away and saying that it would be better for all involved if Lyft didn't try to match people that far away and just returned an error instead.

Now? Neither of those situations have happened in recent memory. I can't remember the last time I got the "no drivers available" error, and at the absolute worst, I might get a driver 15 minutes away in the height of rush hour.

Edit: Forgot one more thing. I used to see drivers who had two phones for both Uber and Lyft all the time. Nowadays I don't see anyone doing that anymore.
One of the small things that may impact speed greatly, is that WASM has a real integer type, it isn't a float like JS has.

Some benchmarking has been talked about before [0], the upshot being C->WASM has a slowdown around 16-25ms. That's a hell of a lot faster than JS in a lot of places.

Unfortunately, as soon as you hook into the HTML APIs, like giving JS a result, you're back to JS speeds.

The tasks I want to accomplish using my PC are more important to me than the tasks you want to accomplish using my PC. If the latter get in the way of the former, I will take whatever steps are necessary to prevent this from happening.

One might reasonably claim that allowing Windows Update free reign prevents malicious software installing itself on my PC and introducing undesirable behaviour.

However, if the introduction of undesirable behaviour by malicious software is a risk, but the introduction of undesirable behaviour by Microsoft a certainty, the incentives do not favour enabling automatic updates.

The best solution, of course, is to switch to a stable Linux distro.

Waymo is allowed to look at the devices and supporting documentation and see if there is any stolen IP.
Another interesting tidbit is that as storage fills up, Android slows down.

I suspect this is an artifact of using the Linux kernel. As said kernel puts a focus on IO ops, and the EXT file systems spend a whole lot of time looking for contiguous free space before committing a write.

Thus if your app do a bunch of writing (say syncing local data with the cloud) at start, it will start quite slowly on a near full Android device.
Alright man. Can you tell me which consumer-facing OS doesn't do those that you mentioned by default? Apple downloads setup files for major OS upgrades as well as system updates automatically without my consent too. I don't want Siri on my Mac too.

As a software engineer, I often reflect on how much my own job prevents or cuts existing jobs for humans. At least in my case, it seems that cutting out human work creates more jobs.

Let's imagine I build a feature that makes it twice as fast for us to close a sale in our pipeline. Do we cut half our sales force? Of course not--we would rather keep all the people and make double the sales. This brings us even more revenue, which we use to hire more sales people and more software developers, growing the company and providing more jobs.

Perhaps this simple logic can't apply to all cases, but I've certainly seen it apply a lot!

Wow, this article is so far off the ruling. Alsup found the patent infringement cases meritless and said Waymo's trade secret claims are an overreach and that Waymo is trying to claim ownership over general principles and approaches in the field.

Uber will be allowed to keep working on the SDCs and on LIDAR. Only strikes against Uber is that Levandowski can't work on LIDAR, which Uber already took action on before the injunction was unsealed, and the discovery rights granted to Waymo.

This article is a perfect example of the extreme media bias against Uber.

Edit: two downvotes within seconds of posting the truth? I know that downvote baiting is frowned upon but these posts are filled with so many people astroturfing for Google, Waymo and Lyft that this comment is going to get downvoted anyways, because some people really don't want the truth to be the most upvoted comment. Honestly all these stories look like the Apple stories that inevitable turn into fanboy flamewars. There are so many HNers with conflicts of interest upvoting these stories and participating in them that almost none of the comments can be trusted as genuine or rational.
