Unfortunately FTP is still used by a concerning large number of support sites with file stores (think manufacturer driver downloads). Personally, I don't mind using a different application to handle FTP as long as the application handling works fine (ie Chrome/FF hand off the URL to an external application like mailto: links, rather than showing you an error page of some sort).

However, I feel like this change has little to do with FTP itself; rather, it might be coming from Chrome's desire to remove the protocol from the navigation bar.
These are usually handled through city property auctions. Bidding usually starts at a few dollars. But you have to read the fine print. They will usually have city, county, state, federal, and private liens on them.

For example a federal treasury auction will discharge IRS tax liens but not state, county, and city charges. I've seen $1mm beach-side homes auctioned for <$100k. But then have $500k+ in state liens on them.

A savvy buyer will get the titles and try to get the liens discharged by negotiating with the other agencies or pay them off. This is factored into the offer they will make on the property. If you think you've stumbled into a method to get rich quick you're sadly mistaken.

We can indeed relate this problem to the “usual” Diophantine approximation problem of approximating a number α by a rational number p/q, but there's a twist.

The “usual” problem, where we want p/q to be close to a real number α, can be thought of as finding Gaussian integers (q + ip) that lie close to the line y=αx in the complex plane, i.e. points z on the lattice such that Im(z)/Re(z) ≈ α.

Here, with α=√3, we want to solve the same problem, i.e. find rational numbers p/q close to α, except that p/q must further be of the form (ad-bc)/(ac+bd) for some (a, b, c, d). Here's the thing: this is precisely the same as saying that (q + ip) is not a Gaussian prime! This is because (a-ib)(c+id) = (ac+bd) + i(ad-bc). (https://en.wikipedia.org/w/index.php?title=Brahmagupta%E2%80...) So any (q + ip) of the form (ac+bd) + i(ad-bc) can be written as the product of two Gaussian integers, and vice-versa.

So the relation between the Diophantine approximation problem and this one is that while there we want to find Gaussian integers close to the line Im(z)=αRe(z), here we want to find composite Gaussian integers close to the line Im(z)=αRe(z).

(Note we can get different "best" approximations depending on how we measure closeness; see my other comment here: https://news.ycombinator.com/item?id=18555240 Also, I expect that as denominators get larger, the primes get sparser, so this becomes closer to the usual problem. Of course in the original post linked here, the goal is to find small solutions, so the difference matters.)
What convenience, though? You can pay for already-hosted Nextcloud and just install and use it.
You mean you can't foresee the unforeseen? No!

But you're right. The moral of the story to Jurassic Park pretty much was "Just because you can science against nature, doesn't mean you should."

But to be fair to, ae. aegypti is technically invasive, to the entire USA. Ridding it TECHNICALLY is a good thing for the local ecosystems. However, I personally don't think the method they're going about it will be as effective as hoped plus it seems like a pandora's box of food chain chaos.

That's kind of where global warming would actually help. Due to the life span and mating cycle, along with egg hardiness, if they have a good drought for about 8-10 months. And then they do extensive hormone pupacide and larvacide treatment. They can nearly eradicate the entire nearby population in one year's time. However, a. aegypti have like an average 800m migration distance within their lifespan (if I remember that right). Thus, they can then do perimeter containment of certain areas to ensure no new migrations into their area. But instead, let's play god and engineer bacteria to fuck with reproductive systems.

For anyone looking for a simpler recap of the event, there's been a 4-part series running at Deadspin that has been an awesome read for me. The last part covering the last 4 matches is here https://deadspin.com/armageddon-looms-over-the-world-chess-c... and there are links to earlier parts in the article. I'm sure there will be a final part covering this victory as well.
I read it more as 'anyone who doesn't support public education isn't a person that should be setting policy for society'.
The coffee shop closest to my house has the same problem. The only times they are open are while I'm at work. They opened right about the time we moved (a little over a year ago), and we were excited to have a play we could go close by. But they are never open when it would be convenient for us.

The dumbest thing in my mind is that they are open for like 4 hours on Saturday (7am - 11am).

I think the problem with that particular coffee shop though is that they lady who owns it also runs a catering / event hosting business, so the needs of the coffee shop come last.
The more interesting thing about this is that it is part of a new type of economics, contraction economics. The global trend toward birth rates below replenishment means that first-world countries are maintaining their population growth through immigration. As some countries embrace restrictions on immigration, and ultimately all countries plateau in their population growth (projected to be around 2100) it means that the driving force behind increases in property value (population increases) will be curtailed.*

As we saw in 2008 curtailing or reversing growth in real-estate can have major impacts on society, but in the future this won't be just a correction it will be a new phase of global economics. There will be fewer humans each year making the total pressure on land values negative. Even before that an aging workforce will cause the total working population to contract (as it already has in Japan). Everything the Japanese do with more land and fewer workers is a canary in the coal mine for the global economy.

One of the great predicates of modern economics (perpetual expansion) will need to be re-thought. In some ways it's great news (more space for everyone after the great pinch of the 21st century) but in others it will necessarily wipe out the speculative aspect of many current growth markets. Contraction economics means deflation becomes a norm not an exception.

* Urbanization means cities will lag behind this reversal.
From the blog:
"I write this as the FreeBSD Handbook does not cover all that information in the 11.13. Power and Resource Management chapter. The FreeBSD on Laptops article part 4. Power Management is from the ancient times of FreeBSD 10.1-RELEASE. There is some information on the FreeBSD Wiki page but parts of it are outdated."

The best way to help FreeBSD (or any open source projects in general) is to submit diffs to the project documentation itself, than to have lots of documentation scattered among blogs (which will soon become outdated also).

The project benefits by having up-to-date documentation, the users benefit by having a single source of truth and a lot of questions in the mailing lists are saved by users not following documentation which probably are no longer relevant.
But how? To me it sounds like a safety feature.
>Now you want to regulate private companies like public utilities?

Most public utilities are private companies. That's why it's called regulation and not nationalization.

>The switching cost in the US of changing phones is going to your provider and trading your phone in every six months to a year.

No, most of the switching costs are the costs (monetary and in unpaid labor of learning new tools and workflows) to users of switching from one platform to another. This empowers the gatekeepers to extract higher rents which, by definition, add no value to society.

>When did not having an app stop people from participating in society?

When people start building transportation access into them or make it contingent to being able to do some jobs it becomes a necessary tool for participating in society. The average car costs over $30k, that doesn't mean we would have put up with things like proprietary gas stations either.
No (or long-broken) tests and no easy (at least partially automated and otherwise documented) way to build and/or run the code locally are the norm for others' codebases I've inherited. Those two things qualify it as "awful" I'd say, all on their own. Especially in languages like Ruby or JS where you're practically crippled in an unfamiliar codebase without tests and/or being able to poke around in the running application. Both being absent is a near-perfect signal there are tons of other problems, of the screw-up sort and not the we-had-to-cut-corners-for-actual-reasons sort.

Comically bad security holes, actual or implicit (framework-created) SQL queries in a for loop for no good reason (well, because the developer had no idea how to use SQL, and hadn't developed an appropriate allergy to unnecessary network communication, are probably the reasons), hilariously misguided attempts to fix the wrong thing to improve performance ("we'll move it to jruby!" well sure but your actual problem is you chose an inappropriate database and are using it poorly, but at least you made your build pipeline worse for marginal benefits, so there's that). Ruby in your node project just to run a very basic task queue (!?). Et c., et c., c-beams off the shoulder of Orion, tears in the rain, et c.

Inheriting something even half-decent is really, really unusual. I wouldn't bad-mouth half-decent. I just rarely see it.

[EDIT] this probably varies a great deal by platform. I imagine it's a bit less common to have a total train-wreck of an iOS app, to pick another platform I've worked on, than something server-side.
If this can get me tables out of pdf's generated by crystal reports it would be a godsend for testing. This has been a nightmare to try and solve, the best option so far has been adobe cloud but they don't offer an API for that. I'm excited to try it out.
I agree with you in general, but I think a better rule would be to almost never rewrite code.

I know that everyone thinks their predecessor was an idiot. And I agree that full rewrites are usually a bad idea. But sometimes, the predecessor genuinely was an idiot, and the code really is that bad. If the use cases and inputs and desired outputs are well documented enough, a full rewrite can be the right choice.

It depends on the size of the system, too. A full rewrite of something as complex as Netscape is asking for trouble. If it's something that can be rewritten in a day, or even a few weeks, it might okay to go ahead and do it.

Of course, by the time you've got enough experience to accurately estimate how long a rewrite will take, you've probably got enough experience to just refactor the old code without going insane.
Also, you can use a tool like https://www.npmjs.com/package/source-map-explorer to see if there's code in your bundle you don't expect!

A rule of thumb from the European Union is that it takes four competitors before prices come down. Two form a duopoly, and it's to the advantage of both parties not to lower prices. Four have trouble holding prices up. Whoever's losing market share tends to cut prices.

Antitrust law needs to reflect the rule of four.

Fuseless – Serverless CFML Lambda Functions
Quite excited for this! We have currently been experimenting with using DynamoDB, and managing our own rollups of our incoming data (previously on an RDS, which is not a good choice for this kind of data).

---

I've seen a lot of people complain about pricing, so I thought I'd share a little why we are excited about this:

We have approximately 280 devices out, monitoring production lines, sending aggregated data every 5 seconds, via MQTT to AWS IoT. The average messages published that we see is around ~2 million a day (equipment is often turned off, when not producing). The packet size is very small, and highly compressable, each below 1KB, but let's just make it 1KB.

We then currently funnel this data into Lambda, which processes it, and puts it into DynamoDB and handles rollups. The costs of that whole thing is approximately $20 a day (IoT, DynamoDB, Lambda and X-Ray), with Lambda+DynamoDB making up $17 of that cost.

Finally, our users look at this data, live, on dashboards, usually looking at the last 8 hours of data for a specific device. Let's throw around that there will be 10,000 queries each day, looking at the data of the day (2GB/day / 280devices = 0.007142857 GB/device/day).

---

Now, running the same numbers on the AWS Timestream pricing[0] (daily cost):

- Writes: 2million * $0.5/million = $1

- Memory store: 2 GB * $0.036 = $0.072

- SSD store: (2GB * 7days) * $0.01 (GB/day) * 7days = $0.98

- Magnetic store: (2 GB * 30 days) * $0.03 (GB/month) = $1.8

- Query: 10,0000 queries * 0.007142857GB/device/day --> 71GB = free until day 14, where it'll cost $10, so $20 a month.

Giving us: $1 + $0.072 + $0.98 + $1.8 + ($20/30) = $4.5/day.

From these (very) quick calculations, this means we could lower our cost from ~$20/day to ~$4.5/day. And that's not even taking into account that it removes our need to create/maintain our own custom solution.

I am probably missing some details, but it does look bright!

And you can get pretty close to being schemlass with the json column, and maybe with the inverted index.
But you don't get the choice, given the applications. It's not clear to me how Plan9 would help with relevant problems; it was tried on Blue Gene at one stage. If I got the choice of something different, it would likely be capability-, microkernel-based, which might actually help with the jitter problem.
Which do you think is more likely to develop students into citizens capable of independent thought:

a) Sitting at a desk. Not allowed to talk unless called upon. Exactly following a schedule determined by authority figures.

b) Being free to move about the room. Able to choose your activity with your peers.A constructivist or "discovery" model, where students learn concepts from working with materials, rather than by direct instruction.

The first describes the typical public school. The second describes a Montessori school https://en.wikipedia.org/wiki/Montessori_education

Given the inertia of the system, it is unlikely that the public education system can be reformed from what it is. Why not support parents choosing a school based on what they consider best for their children as long as the schooling meets minimum standards? However, when politicians support this options, there are people that paint them as villains for "not supporting public education". Someone can support "public education" the concept of educating the public, and not support "public education" the system which is often driven by various special interest groups.

> USB has always "just worked"

I remember plenty of issues with USB device compatibility. Mostly when someone failed to follow the standards, of course—fully compliant devices and host controllers have generally worked well together, at least since USB 1.1. But there are a lot of non-compliant devices out there. Bluetooth isn't much different in that regard: if both devices follow the spec it tends to work well, but it's much more likely that one or both of the devices takes a "shortcut" or two in the name of saving a few cents. The fact that Bluetooth devices are typically battery-powered and thus strongly incentivised to cut corners to save a few milliwatts doesn't help.

However, the standards certainly aren't perfect even when implemented correctly. The most awkward aspect of the Bluetooth experience, in my opinion, has to do with pairing. There shouldn't by any limit to the number of simultaneously paired devices. They should just exchange signed credentials during the pairing process, and either device (but typically the more general-purpose one, such as the phone or laptop) should be able to present these pairing credentials later to establish a connection. The headphones, car stereo, or other special-purpose, storage-limited device shouldn't need to remember anything about the devices permitted to connect.

The idea is immutable micro-transactions to track operations in a complex inventory system. Consider a situation where a customer finds a nail in their banana. This 'blockchain' db could be used to recognize where the banana was sold, what truck delivered it, where that specific banana and was sourced.

It can be an interesting solution or vaporware depending on your level of interest. I personally think micro-transactions and blockchain do not go well together but reading debates about the tech is still interesting.

I actually code in the command line, usually. Vim.
I've often said the same thing. I think when there are too many, it's not useful (though in some very real sense, every artist is its own genre), but of course one genre is useless too. Some people say "why have any genres at all", but as someone who's tried to explore musical connections where I haven't been able to find established genre names -- like between old folk music from some smaller countries, or the continuum of music featuring accordions, horns (especially trumpet and clarinet), acoustic guitars/lutes, and strings that goes from Russia down to Turkey and beyond -- it can be really painful to find related music and artists without good genres.

The trick is a good balance, and I personally find that electronic music and metal (as another poster mentioned) have genres that are often too small for my purposes.

That makes it impossible to properly implement POSIX on top of it and seems like a poor design.

The correct design is to have both a "root" and a "current object" associated with every "file descriptor object" and allow ".." to work up to the "root" (and thoughtfully handle cases where the "current object" is moved outside the "root").

You can't do it with paths because that doesn't track directories being renamed, that would cause the descriptor to suddenly become inaccessible in the middle of an operation.
