You are primarily going to get responses from people on threads like this who like and use DDG regularly. Selection bias. If you didn't find DDG useful, you wouldn't be using it, and probably don't have much commentary to add.

I don't see them truly competing with big budget search engines, but it's probably easy enough to make decent money from keyword ads and if you can sell the brand, you can get enough users to cover a smaller machine footprint and R&D budget that's orders of magnitude smaller.

The results are probably not awful (I don't use it). Result quality gets exponentially more difficult as you try to push that boundary, so you can probably get 80% of the quality there with 1% of the investment. The results may be good enough for plenty of folks, but I highly doubt they will ever be better than the big budget search engines.
I've read that it can only be done once every 7 years.

Ah, the old "trick a system process into overwriting a link destination" ploy. That used to be a popular exploit method on UNIX in the 1980s.
Incidentally, I was looking into these citations yesterday and many are serious ones. Which is worrying.
I use a metasearch engine (searx) for precisely this reason. It aggregates results from any number of search engines, sending request to them in a very generic, non-identifying form, then displays them all on one page with a tag next to it to indicate where the source of the result came from. You can host Searx yourself or use a public instance, but using the public instance means you trust the operator to not log/filter results/inject ads(I don't know if folks do, but it would be possible) or do other nefarious things. It's pretty easy to host it yourself..
1. Skill Building. I.e., the same reason we start teaching them to write letters in kindergarten even though they won't have a practical need for writing until late in elementary school. So that there's a foundation to build on later.

2. Feedback. E.g., there are some good fractions apps that help students understand what it means to "divide" a set of things into a set of groups of things. you can do that on pencil/paper or with other props, but there's no tight feedback loop.

It's unclear whether (2) is strictly a good thing; learning how to validate your own results is also an important skill...
>The robocalls cite no evidence supporting the claim that net neutrality rules will raise cell phone bills and slow down Internet service.

Because only people in favor of Net Neutrality are allowed to do that. Remember before the repeal, proponents of Net Neutrality claimed we would all have to pay more or receive slower service? I certainly do.

I'm not in favor of these robocalls any more than I'm in favor of Net Neutrality supporters lying to people. arstechnica are pure hypocrites. They did exactly this, now they complain about the other side doing the same.

>Perhaps your ISP will throttle the high-bandwidth BitTorrent file-sharing protocol—or whatever replaces it. (Remember the Comcast BitTorrent debacle that resulted in Comcast paying $16 million?) Or maybe your ISP will just charge you extra to use it.

No you are not correct and I've been downloaded by people that don't know the history of DNS Certification Authority Authorization (CAA), which became required in 2017.

Let's Encrypt launched 2016, which meant that unless you were doing HPKP with long pin times and had traffic that already had hit your endpoint, if someone was on your gear (but lacked your private key) they could impersonate you for free and with no messing around with stolen credit cards to CAs.

To verify for Let's Encrypt—contrary to what you recall—all you are required to prove is that you can set a specific value at a path for the domain you are responsible for.

DNS verification is an option; but few use it.

Let's Encrypt has meaningfully reduced the barrier for certificate forgery. Every startup should set CAA headers now, but few do. It's still good that Let's Encrypt exist but it has its drawbacks.
User defined types are __no__ different than "native" types.

You are talking to the llvm compiler, sure you are talking in Julia most of the time, but if you happen to want to talk in C or FORTRAN or ASM in the middle of your high level script, just do. No marshalling of I/O or data structure impedance it all compiles the same.
I should add the caveat *in the United States. It would obviously be a pretty dumb comparison for Singapore or Reykjavík. I'd also add that the 10s in Fahrenheit also make nice comfort delimiters. 20 is frigid, 30 is ~freezing, 40 is cold, 50 is cool, 60 is warm, 70 is room temp, 80 is hot, 90 is excessively hot, 100 is oppressive. Again, obviously you can do the same thing with the 5s in Celsius but it does work nicely for the average person.

I'm not really saying this is better than Celsius, just that it's understandable why it's not changing as quickly as some would like. I will say that the industries that have specific reason switched fairly quickly. For instance, aviation uses feet, inHg, statute+nautical miles but does temperature in Celsius because pilots overwhelmingly care about whether it's above or below freezing outside.
Why does this story get flagged?

Is it a unreputable news source?

Is the articles information factually incorrect?

Is it off-topic or otherwise astray from the guidelines?
I've worked most construction trades and built three houses that my wife and I designed. The devil is in the details. Some machine layering out concrete like a 3D printer is something I saw in Popular Science decades ago. I always wanted to see it happen. Even with a giant 3D printer, you'd have to have people there to lay conduits for plumbing, electrical, etc. The devil is in the details and most of those details are hidden from view. Out of sight, out of mind for most people. Once you do these jobs you realize there is so much that goes into a house.

Once a house is built in a way that is "out of the norm", you'll raise a few eyebrows from inspectors too. We had that issue and it was because it was a timber framed house like someone might have made 100+ years ago - no bolts, nails screws, metal brackets, etc. It was 100% put together with joints and pegs. The inspector only walked around with his jaw on the floor. We finally sat him down to show that we did our homework and followed engineering guidelines - but they weren't guidelines that he was familiar with.
I keep my house at 78 in the summer. Enough to feel comfortable compared to outside, especially with the humidity reduction. When I'm at home I wear shorts and a light T shirt. Commercial buildings at 70-72 are uncomfortably cool to me when the outside temp is 90, but I agree that 78 is probably too warm for typical professional work attire.
It's a good article and the strategy is appropriate as part of a more diverse portfolio. My point wasn't that the article was bad, but that holding till maturity only gives the illusion of bypassing interest rate risk.

"The only real risk to principal is being locked in to a rate that's lower than inflation for an extended period."
in fact the IRS says it costs about 20 cents/mile more
Don't tell anyone that thinks A/C comes at a high environmental cost, anything about what would be needed to make Mars viable for even a single person to stay there. They might blow a gasket. Forget about if we get to building a small village on the Red Planet.
Ive heard of people using propane as a refrigerant over 30 years ago and it probably goes much farther back. Back in the day it was considered much less efficient, but of course those super effective old refrigerants it was compared to aren't sold anymore so it might not be far off.
Ublock origin with all filters enabled is the only thing that makes Youtube usable in my opinion.

Youtube is a horrific service. The recommendations are terrible, the UX sucks, too many ads, they dont know how to use the sreen real-estate.

I freaking hate youtube.

WRT to real-estate, I see that the video I am wanting is taking up ~20% of the screen, then there is a list of completely unrelated content, and I have to click to see the date of the submitted video.

The UX is different on every single device. Phone, machine, ipad, browsers differ... its just a mess.
Thanks! That review alone is worth a HN submission and I'm not even a hobbyist physicist by any stretch of the imagination.
Dell have computers with Ubuntu pre-installed.
Even really nice furnaces lose some energy up the flue, so they are less than 100% efficient. They hit ~95%, which is really good, but it's less than 100%.
I got my report from them, it's a mix of disturbingly detailed and laughably inaccurate.
‘Autonomy’ Review: Fast-Tracking a Driverless Car
It's fine now, following CAA records is now mandatory, but prior to 2017 we didn't and even now most websites don't use it. CAA should be mandatory in a Let's Encrypted world because it's now trivial to create a HTTPS cert. It no longer requires stolen credit card details.
Etching doesn't have to be super messy if you are experienced in it and have all the equipment set up. I would also recommended using ammonium persulphate over ferric chloride as it's a see-through and a bit less nasty.

I few months ago I would have dismissed DIY PCBs altogether in a heartbeat. But I visited my friend who etches PCBs on the regular and as long as you are OK with the limitations there
is a lot to be said for holding your design in your hand minutes after having layed it out. I wrote a bit about this experience in my blog: https://blog.monostable.co.uk/posts/etching-oscillators-in-z...
The Chip That Changed the World
ARP cache poisoning occurs at the switch not the router. It is an awesome form of attack, but access to the switch and the availability of that compromise are limited in scope. A single switch can only have so many machines connected even with VLANs. It also requires access from within the local LAN.

I really don't think anybody is thinking of ARP poisoning when all these comments here mention public facing MiTM attacks merely because a page is served with HTTP instead of HTTPS. Since ARP is only layer 3 it really doesn't care if the page is sent via HTTPS and works the same either way.
It will if/when Crostini becomes mainline. For now, I'd agree - the iPad has a browser, and that's all the Chromebook has.
My family built our home starting in about 1990 when I was in high school. We built the entire thing ourselves. The only parts we didn't fabricate were the cabinets that my uncle built. We built a 3 bedroom 2 bath home with a study. I really cannot remember how big it was.

We built a 'pier and beam' foundation that created a cawl space under the house. We did our own plumbing, electrical, and hvac. We built in the country where the required inspections were minimal.

Even after having gone through the experience, I'm not sure what pointers I would give you here other than be prepared to do a lot of hard work and, if you finish, you'll probably be really glad you did it!
Why Virtual DOM is slower
Why are you surprised? Zed Shaw is notorious for being belligerent.
If you go to Google Scholar and search "Tai's model," you can find that this from 1994:

"Tai's formula is the trapezoidal rule"

http://care.diabetesjournals.org/content/17/10/1224.short

As well as Tai's response:
http://care.diabetesjournals.org/content/17/10/1225.2.short

As a fellow academic, it seems to me like Tai wasn't really claiming to have reinvented the wheel here (or maybe I should say the area under the wheel). It looks to me like she took what my psychologist friends call the "Least Publishable Unit" (LPU) too much to heart. She claims, in the response, that she was asked to publish it by some colleagues so that they could cite her in a paper of their own; it's unclear to me why they would need to cite such a thing, but most likely it was just the typical explanation - where you cite your friends at any possible opportunity, even when they recapitulate Isaac Newton ;)

Granted, I think it's a weak rationale, but I suspect it's not so much that no one involved knew calculus; it's more that they wanted to drum up more citations for people inside their field rather than outside. In fact, I see that even the people who wrote in to protest managed to rack up 7 citations.
So how do we make POSIX II happen?
In all seriousness, are we not allowed to complain about glitches now, particularly if the glitch means 'increased diversity'?
As leephilips said, there's a package, but it's nowhere near what Mathematica can do symbolically. Julia was more intended as a numerical Matlab replacement.

However, it could have a lot of potential here. It is a fully homoiconic language with real macros, so it could be a very good fit for symbolic math, just as Maxima is built in Common Lisp.

It would be great if there was a real effort towards that. Mathematica is still really the only game in town.
A good example of a game that lets kindergartners play with concepts that even kids much older often struggle with is Dragonbox: https://dragonbox.com/

This kind of self-directed, exploratory learning can be very effective.
Ask HN: What type of work allows you to write lots of fun algorithms?
Hey guys,

As a web developer I've realised how rarely I get to actually write a nice meaty algorithm.

It's always highly enjoyable when I do and I find that even though it's more complex than plumbing CRUD apps together, I create way less bugs because my mind is fully engaged on one task.

What type of development work out there allows you to spend lots of time writing fun algorithms?

Thanks!
Don't put your home near place names like "floodville", "lavafornia", "poisonwell" or "mudbottom". Is surprising how many people still insist (and are allowed) on building their home inside the floodable areas near rivers. If there are very old trees or even better very old houses standing around, put a green checkmark in your notebook.

Let the floor, columns and beams to be managed by a professional. Furniture is heavy and your house will need to stand a lot of weight. You can live with a door misplaced opening against the light switch, but not with a treacherous floor.
The anti-herd is real.
which just shows what a huge scam AVs are nowadays
I see the same trend on Indeed.co.uk. In the last year or so there have consistently been about 40% more Django roles than Rails in London. At Angel.co, however, Rails is still more popular. I put this down to the general increase in Python adoption rather than anything specific to Django.
On a side note, Disney will pull its movies from Netflix to launch its own service, Disney Play.
Ha!

For whatever it's worth, physicists aren't necessarily up on everything written by the medical community. Take for example, these letters to Diabetes Care written in 1994 criticizing Tai's article soon after it was published:

This is sad because it shows that general enducation standards have dropped dramatically across the board given that this sort of stuff really should be (and used to be) known by every high school student..
Nobody's denying the facts you gave...lack of competition, lack of transparent pricing, etc.

But to use people's lives as leverage to extract absurd amounts of money goes well beyond being immoral, it's just downright evil.
Something in our soul has a far more violent repugnance for true attention
I don’t understand. The view would be the same. It would be the same as having as having roofs. Just slightly raised and maybe a different color. No problem with views.
Well it's 2 years later so I hope the same tech would be cheaper ;)

What would they add beyond sci-hub?
Other note-taking tools generally do it by breaking strokes into lots of little line segments, each with a different width coming from the pressure. It works pretty well, and if the program stores the pressure-location data, the stroke width can be adjusted later. I do this all the time in Squid on Android, and have extracted stroke data from PDFs it exports.
I have a relative sick with cancer right now and I’m seeing this first hand. Hearing stories like this you hope it’s a one off, but it’s absolutely the norm of how insurance companies operate.

My aunt is still employed, fully insured, and every day is a fight between her and her insurance company. They randomly deny claims for chemo treatments, and put her through invasive procedures to verify the disease after doctors formally diagnosed her.

The list of landmines they strategically place that could cause her to lose her insurance seems to only grow. This payment isn’t made on this date? Insurance gets cancelled. This form isnt filed on this day three months from now? Insurance gets cancelled. Forget the fact that she is too sick to work; her insurer is already busy trying to figure out how to not pay.

Unless you are wealthy enough to pay for everything yourself, everyone in the US should expect to be left behind by the health insurance they’ve paid their entire life for as soon as the insurer can figure out how to do it.

"Ich bin wirklich glücklich, talentierte Hochzeitsanbieter zu nennen, aber es war gut, dass unsere Fotografen eine Ausnahme waren, weil Robert und Gail in der gleichen Agentur in Gails vorherigem Leben als Grafikdesigner arbeiteten. Gail und David sind unglaublich talentiert.

Wir können wirklich nicht in Worte fassen, wie sehr wir unsere Fotos schätzen und das Video hervorheben; Wir waren total hin und weg. "

Is this the complete "book" the racist Jeong is famous for having written? At 79 pages it's basically a pamphlet.
I will add another couple of points.

In kindergarten (many decades ago) sometimes we were given individual assignments, such as sticking figures in the right place, coloring things, basic counting... But other times we were forced to interact with our peers and "play together."

As someone who has always struggled to interact with other people, and who had not met any other kids before/except in kindergarten, I think those times were very formative. Hard, but formative.

I still struggle with people as an adult, but I think I would be worse off had I spent that time in front of a screen, whether touch or not, instead of interacting with other kids, including hard times like being excluded from the group with they best toys and stuff like that.

Also, I was using a keyboard (Model M!) as young as 3 years old, and the Microsoft Mouse not much older. I remember watching my dad add the mouse ISA card inside the computer, and learning to use three 5" floppies in the right order: first the DOS one, then the mouse driver one, type MOUSE.COM or something similar, then the Windows 1.0 floppy, and finally I could use Paint or Othello :-)

I think early computers increased my ability for concentration. That's interesting, considering modern devices are said to decrease it.
DuckDuckGo is a great search engine, I've been using it for a while. The only thing that stops me from fully moving to DuckDuckGo is eseential DOM load speed.
Google search results page loading speed is two times faster.

DuckDuckGo needs to hire a Frontend wizard that will address all the issues with load speed and hopefully make it quicker than competitors.
https://duck.co/help/results/sources says they have 400 sources which is special cases like Wikipedia,etc. The core search is powered by Bing (Yahoo uses Bing) and Yandex in Russia.
Does anyone know who NYCMesh peers with? From their FAQ:

"Are you an Internet Service Provider (ISP)?
No, we are not an ISP, we are a community that shares ownership of a network. Collectively we have our own internet connection at our “supernode”. Also some of our members share their own internet connections.

Our network peers with other networks at an internet exchange point and provides access to the internet without traditional ISPs. We are a non-profit project of the New York chapter of the Internet Society (ISOC-NY)."

I'm confused. While I definitely believe that you are correct in that assessment, the example you gave doesn't seem relevant.

Mary Tai was an EDD (doctorate of education), not a physicist. and the reply was from the mathematical community, not the medical community.
Hi Marjin, I've been extremely impressed working with Codemirror. The event API is really easy to work with and I love the ease of switching syntax modes and color schemes.

I'm building a product around CodeMirror and as a vimmer, I intend to carry Vim mode with me.

Will CodeMirror6 implement vim mode in a similar fashion?

I'll send you some coin either way, thanks again for developing such a great project!
As someone whos AC at work died during the summer in Dallas my productivity after the AC went out was a quarter to a fifth of my output before. The cost to my employer for that reduction is well worth the cost of AC.
This post reads perfectly if you replace DDG with "Google" and believe it's 1999.

Sure Google had a vastly superior algorithm but I don't think too many people really grasped that at the time.

Why should string be fundamental?
I wasn't going by any sort of order. Repair seems to have been left out on the 3 R's.

I remember opening up equipment from before 1980, and you were greeted with circuit schematics, diagrams, and replacement part numbers. Replacement of a single component was usually simple, and very cost effective. For some, it may take a few weeks to get the thing, but arrive it did.

Now, people throw out wide screen TVs and all sorts of electronics. Why? A cap popped, or a resistor burned out. Someone spend $399, and it was foiled by a $.05 component. But what about swapping the board responsible? Nope, it's all "non-user-servicable" aka buy more crap you lazyass consumer.

And what this cat litter cleaner ultimately is; it's a device that does a thing as long as you keep feeding money in it from the approved source. It's not like a pillow, or a chair, or a tv. It would be more like those, if it weren't for the fact that built in is a device that obeys its owner - and you aren't that owner; you're the owned.
