Measuring by occupancy rate isn't accounting for landlords withholding units from the market in the expectation that they'll find a tenant/buyer willing to pay more for them later, which is an allocation of supply the same as if someone was living there, and is caused by overall supply constraints creating the expectation of continued high rents.

It also fails on the other end because there are many alternatives to local housing other than homelessness, like selecting less local housing with an unreasonably long commute or living in units designed for fewer occupants in violation of the fire code. You essentially have unaccounted for over-occupancy. People having more money doesn't solve any of those problems without more housing for the money to buy, and interferes with solving homelessness as well because higher wages in general could cause people in those situations to move to existing unoccupied units before the existing homeless do.

I periodically think of getting one, but it would only work for a section of the house, albeit the section that could use the most regular vacuuming. But that same section is also where there tends to be the most clutter/cords laying about, etc.

In the end, my compromise was to get a good cordless vac which I can run for a few minutes if the crumbs and other debris get too objectionable.

Kentucky is 75% coal powered, mostly using old existing coal plants.

As those plants age out of their usable lifetime, Kentucky utilities will have to choose between some combination of renewables and storage or natural gas or nuclear, all of which have higher costs than operating the defunct coal plants, but lower capital costs than building new coal plants. This will result in a rise in their prices over time.

Of course, comparing the future costs of new non-coal plants doesn't account for the huge existing public health and environmental costs of burning coal for electricity, which would be avoided by any of the other technologies.

Whether the machine learning model is "sophisticated" doesn't seem critical on the face of it.

I guess it depends whether there are a lot of non-pothole events that look like pothole events to "naive" signal processing. Do you need deep learning for this problem? I don't know but I would be skeptical without a citation.

But I am interested in more info and examples. If someone can give a bunch of examples I would adjust my view.

Of course there is no guarantee truths about the universe are simple. Newtonian mechanics is extremely simple, yet it is only true as a limiting case of relativistic mechanics, which is not as simple. Maybe relativistic mechanics is only true as a limiting case of an even more complex theory, et cetera.

What we should value is not simplicity, but power of explanation.
The Rise and Fall of the Carbon Dioxide Theory of Climate Change – Rex Fleming
Yes, it is true, many programming they don't do such a good job. I do try to make better software, but will not always succeed. Also computer hardware is becoming too complicated too actually, I think. I generally don't add so much dependencies to a program though. Some people (including myself) do still write DOS programs sometimes. The web browser is too complicated. I use IRC and NNTP, I think they are much better anyways than Slack and so on (and even this HN, too, I think). I do program in C (I use other programming languages as well, but mainly C). Many programs I think have too many animations. And a lot of programs, they just write it stupid!! TeX is good and it still works more than thirty years later, and is fast, too. But anyways I don't like WYSIWYG, so that is why I don't use LibreOffice and Microsoft Word and so on.

That's one way to lower price, but in an industry of razor sharp hardware returns if you really want to make something cheap you do it by getting money from services and if those "services" include interest based advertising then it's even better. Just look at why all modern TVs are "smart TVs" and default (often hard to disable) "call home" tracking features.

The internet is already a huge step up in communication from 20 years ago. Turns out people use that to find ideologically likeminded people meaning tribalist movements everywhere are stronger now than before internet came along. 90's were full of optimism about how tribalism could be overcome that is completely vanished now.

From the same technological situation you describe I can only think of how people would use that only to further isolate themselves. At least today, physical location sometimes dictate you have to interact with people outside of your own social class and background. What you describe could reduce that, making every one retreat even further into their echo chamber.

People already live in close proximity to millions in cities. They generally don't hug each other; more fixated on rushing past each other, avoiding eye contact.

The gradual return of symmetric connectivity, which is underway today, as well as edge adoption of IPv6, could/should usher in a revitalized era of peer-to-peer and other decentralized computing models.

Peer-to-peer models last thrived when connectivity was predominantly symmetric (e.g., the early days of DSL) and faded quickly as asymmetric connectivity became mainstream. I think the decline of decentralization and the rise of asymmetric connectivity are intertwined; neither necessarily caused the other, but they are correlated. One could argue asymmetric connectivity became popular because users only wanted to consume rather than share/serve. But similarly, people stopped sharing and serving because their connectivity discouraged that use case.

Today, symmetric connectivity is returning, such as in the form of 1G/1G fiber connections to the home. Combine this with infinite static IP addresses, and ever rising edge compute capacity, and I think decentralization is inevitable. I won't predict the magnitude, but as a fan of decentralization, I personally hope it is at least significant.
> if enough of them were sufficiently unsatisfied for a long enough time there would be a revolution of some sort

That's precisely what has been happening periodically since we started having governments and states (around 8000-10000 years ago).

One way to measure the value of a government is to estimate how much people would voluntarily pay for the government services if they were not forced through taxation and inflation. As governments are highly inefficient and bloated, most likely nobody would pay the services they provide, and would prefer more efficient free market alternatives if they had a choice.

Now, governments still have to give something back in order to avoid an instant revolt. Modern governments do that through debt spending, meaning: they make the future generations pay (through debt) for the "economic growth" that the current generation enjoys.

Wiping all data in Google Chrome is enough for Google to lose track of you.

Windows 10 leaking personal data hasn't been conclusively proven by anyone in the entire world. There's no evidence Microsoft has ever downloaded a single file off Windows 10 PCs (except for telemetry, e.g. application minidumps, which doesn't uniquely identify you, or contains any of your personal documents). Disabling telemetry in Windows 10 isn't too difficult either.

There's a lot of unwarranted mass hysteria in regard to the most innocuous things in this world which is perhaps an indication that people have no other real worries to attend to.

Even this post about "staying private in Android" is overblown out of proportions. Yes, there are individual apps which abuse your data but you can get rid of them.

Yes, Google assigns a unique identificator to your Android device but that doesn't mean this data is leaked/sold left and right.

And no one is even talking about the fact that US cell operators have been implicated in tracking their users 24/7 and it's not apparent they've stopped doing that.

Your cellphone company (which also serves for most as an Internet operator) is already a threat enough not to use any cell phone at all.

Then there are technologies to break into cellular networks by impersonating cell towers and monitor users against their will and I'm quite sure this feature is used and abused to no end by at least three-letter agencies in the US.

If you're an average American you're passing by dozens if not hundreds of CCTVs daily which are monitoring your whereabouts 24/7.

Privacy in this world only exists for those who don't use the perks of our modern society or who's quite rich and can afford their own island without dealing with the rest of the world.

It is generally not the rich that resent it. The rich simply see taxes as a cost of doing business that they should attempt to minimize as they would any cost.

Then again, we didn't understand methylation - we are starting to get that.

I expect breakthrough about 5 years after we understand the pathways to differentiation and know how to do/undo methylation.

See Aubrey de Grey Wilt idea- but take it with a pinch of salt too, as cells with short telomeres tend to do bad things and grow cancerous. Think about the opposite: infusions of stem cells turned young again (telomeres), then primed to differentiate into what we want (ex: knee: cartilage)

Re: unused computers: I don't see technology on the horizon that would tackle usage of unused systems in any way that could compete with the low-friction of something like AWS. I'm not saying it's impossible, only that it doesn't seem like a problem that is getting much attention.

Re: Amazon: Most of the other venues you mention are secondary markets for the exact same sellers. People have their own Shopify, Etsy, Ebay, etc., storefront but then also sell on Amazon because that's where so much of the market is. As far as I can tell it's an increasing trend in that direction.
I'd love to know exactly how you figure it's more efficient. Sure, it's more efficient for the bureaucrats, but for the market as a whole? If you give me $1,000 a month, I can promise you I won't just be spending it on my needs every month. Even people in massive debt don't always spend towards their needs effectively.

> All of these problems are easily addressed by using smart switches instead of smart lights.

This is so true. I really wonder about all the people installing these WiFi enabled light bulbs into lamps that end up being connected to some regular dumb switch next to the door in the wall...what's your rationale for putting the "smarts" in the bulb and not the switch, the device whose sole purpose has always been to stop and start power distribution to a dumb bulb that just glows when it gets powered?

The failure mode of augmented switches, if the smart control stuff for some reason doesn't work or is not accessible, is super obvious and simple: they just revert to being a switch on the wall.
And it's not just about that, it's also often just more convenient to enable the light the old-fashioned way by touching a rectangle when entering a room. I'm very satisfied with my light setup, allowing control of the living room lights via programmed conditions as well as by a Logitech Harmony remote. But most other members of my family tend to ignore these and just like to use the switch. Sometimes I do as well, like when entering or exiting the room, but I wouldn't want to miss the additional remote control options. With the smarts in the switch (and the home control server behind it wiring it all together), we're all satisfied.
I know quite a few game devs (side-effect of both living in Malmö and being active on the TiGsource forums) and if there is one common thing I hear about Unity it's how it does not seem to care at all about backwards compatibility, and how upgrades can completely screw over projects.

I don't know what the story is with Godot (beyond the breaking changes between 2.0 and 3.0 that was mentioned in the linked blog post) but if that is a lot better then I can imagine that some game devs might be more interested in Godot for that reason too.

Those of us doing it mostly roll our eyes at how VCs and (especially) marketers describe it, so I agree with you, but the "is it ML or stats?" conversation has been going nowhere for as long as this round of AI hype has been here.

That said, uber and lyft certainly benefit from much more interesting ML and stats than just "simple statistics." For example, setting prices and incentives to properly balance the driver side against the rider side of the marketplace.

> The fact that it's open source is also big, because there are often bugs in the Unity engine that I can't fix since I don't have source access.

And very bad ones, at that; which will persist for years and several major versions.

For instance: let's say you have a game that supports user generated content via loading asset bundles. This being the lowest barrier to entry for games to leverage the unity editor for UGC, it's quite common.

Well, now and always, and known and reported since at least 5.2, any asset bundle that references a class not found in the compiled game client will crash the client on load.

The only work around is to write your own asset bundle inspector and pre-analyse on load.

I feel like there were others but can't find them.
The tl;dr of the technique is to use /proc/$pid/mem to overwrite the stack. (Since you don't have direct control of the instruction pointer this way, there's some complexity in loading shellcode somewhere and having the process return to it to get it to usefully execute your code, much like an actual stack-corruption exploit.)

On a normal Linux system, /proc/$pid/mem is protected by the same kernel permission check as ptrace, and a Linux security module like Yama, the thing that disables ptracing unrelated processes on Ubuntu etc., will also block this tool (which the README mentions). It seems like it's mostly useful for cases where people are blocking the ptrace syscall (like Docker's default syscall filter, maybe?) and not loading an LSM.

Cool demonstration that blocking the ptrace syscall isn't sufficient. By the way, blocking /proc too isn't sufficient either: there's the process_vm_writev and process_vm_readv syscalls that work like writing/reading /proc/$pid/mem. I think it's harder to write a robust tool using only those syscalls, but I wouldn't bet on it being impossible.

If you really want to do syscall filtering to confine an untrusted process (as opposed to reducing attack surface from potential bugs in otherwise-permissible syscalls, which is I think Docker's goal), you need to start from empty and allow syscalls instead of starting from full and blocking them. Alternatively, maybe just run the untrusted code as another user account or something.

They mention that Mozilla supports their HTML5/WASM efforts, which makes sense
Yup! I got started with this book and automated a bunch of things in one of my internships about 3 years ago. I was in a network administration focused program in university. I decided to automate a ton of the repetitive tasks that people on my team had to do (creating config files with specific line endings for finicky cisco devices, creating an inventory of all our network connected devices, parsing and comparing large spreadsheets, etc).

Looking back, my code was absolutely atrocious and I was on a team of 1 (just me) but this book and that 4 month co-op is essentially what got me to transition from applying to network admin roles after graduation to applying and getting a platform engineering focused role and focus on software development. It's what I've been doing ever since!
