Or questions that there are no good answers for. Would this subject be covered in journalism school...is there such a thing as journalism school? If not should there be? How are the "free and impartial press" reporters hired other than by billionaires and the like?

The iPod Touch was basically taking an iPhone of the same vintage and cutting out the cellular modem. So a lively app ecosystem was ready to fall out of the box.

MS had nothing comparable to build the Zunes from. Windows CE/Mobile was a technically valid potential base, but it wouldn't easily convert to a sexy consumer-friendly system.
I made a similar web app a while ago.

However, in my web app, I sort by reverse order by default to show the most heated submissions first, with the option to reverse the order.

As a bonus, it also has past archives. Feel free to check it out:

So you're saying, "Grow something unusual."? Something like... water chestnuts? Or mint?

Convert your wheat crop to mint?

Commodities are commodities because there is such a huge demand for them. Niche products are not some super easy to get rich with scheme.

If you want to succeed in the mint market, you'd better do you homework, execute perfectly, and get lucky. Just like in the commodities market.

The Turing architecture is also used in Quadro RTX cards, and those have a ridiculous amount of VRAM.

Is there any professional/computational use for these RT cores beyond raytracing?

One case that comes to mind is perhaps raytracing acoustics, and although interesting it's technically still raytracing.

As far as gaming is concerned, personally I'd love if the RT cores could contribute—however inefficiently—to rendering workload in non-RTX games. It's annoying that 50% of the die is allocated to hardware that requires feature-specific implementations.
There is also Samsung doing 7 nm.
I say no. I use my iPhone heavily as a synth or guitar processor etc. Bluetooth latency is too high to make it useable wirelessly so I require a hardwire into a mixer to perform. The iPhone has the lowest latency audio stack of smartphones when used with a wire. This is important and removing the headphone jack means dongles or latency. What makes this especially bad is that the iPhone camera connector dongle is already required when plugging in many MIDI controllers. This has prevented me from upgrading beyond my 6s as many of my apps are challenged without a real-time audio output that doesn’t also use my lightning connector which I need for the camera connector.

The other reply to this comment does a good job of summarizing a lot of the problems Peterson poses. I would also say he has a cultish following, which means he holds a fair amount of influence, which he doesn't always wield responsibly.

I have also consumed a lot of Peterson content, and much of what he says has a lot of value, and not just for young men. He also holds positions I think are indefensible, unscientific, and highly prejudiced. It is important to embrace nuance and subtleties, loving parts of what we dislike and disliking parts of what we love.
I think this falls between the cracks. Serious programmers (most HN readers) think it is too basic (sic). Non-programmers prefer hacking together cloud apps using Zap or IFTT where no code is needed. Enterprise just want thousands offshore maintaining legacy code
New versions of BASIC are surprisingly common (heck, I even have one that's gotten some super-nice comments).

Mind-blowing BASIC example from the 1970's:

100 A$="ABCDEF"
110 A$ = REP ("123", 4, 0)
120 PRINT A$

The result is ABC123DEF -- at position 4 (strings start at 1), replace 0 characters with "123". So the REP function looks at the statement it's part of, finds the variable that is being assigned to, and uses that as the starting string (!). It's kind of like a function, only with a weird implied variable that only works in an assignment.

You can't just PRINT the result directly, because then how would REP know what the string to change is?

Nowadays "weird" syntax has some solid foundational reason why it's useful or important. This not-really-a-function, though, simply has no justification whatsoever.

(This example is from the BASIC embedded in the Tektronix 4050 terminal).

There are enough variants of BASIC that there's a really nifty handbook with the differences at https://archive.org/details/Basic_Handbook_2nd_Edition_1981_...
What about cloud providers like google? They need high performance throughput in their nics in combination with security. It sounds like that benefits from custom chip design.

There is much truth to what you write. However, the problem occurs when Peterson conflates his politics with his advice for how individuals can improve their lives. As an experienced clinical psychologist with some acquired life wisdom, he seems very well-suited to providing positive, beneficial messages to individuals. His political punditry is not founded on the same sort of genuine expertise.
Have you actually read about any real voting machines presently in use? I find it extremely hard to believe you have done so and come to this conclusion.
Rails isnt very intriguing in 2018, atleast for the minds that seek novelty. A Blog Engine in Rails in 2018 is like, A Website written in Java in 1999. If you are someone who is re-visiting Rails after a few yrs, you realise they haven't learnt anything, they are still creating breaking changes entire API rewrites, new methods that do the same stuff that old ones did, but atleast makes it sound new. Mostly vanity changes.
We already saw that the Threadripper 2990 is starved for bandwidth between Zen packages due to the infinity fabric design.

So you get incredible cinebench performance (and some other 'embarrassingly parallel' workloads), but it doesn't scale to other kinds of programs that have more interthread/interprocess communication.

I guess it remains to be seen what happens with EPYC, but my initial guess is that it will have a similar infinity fabric design to hit 64 cores/128 hyperthreads.

BTW has anyone done an R mclapply benchmark on Threadripper 2990? I was set to buy one until I saw the uneven benchmark scores.
> I think C dominates because it's a language many embedded guys, who often are EE's not CS graduates, can get their head around.

I think that's a pretty unfair characterization.

> C is also deterministic, unlike, say, Python, where you don't have a compiler to catch type errors and things can blow up unexpectedly at run time.

I've been doing a little prototyping at work recently with micropython (not my decision), and this is one of things that frustrated me. There's also lack of good tooling compared to (embedded)C/C++, and the lack of libraries. Regular pure-Python libraries either don't run, or perform very poorly because they don't stick to the subset of the standard library that's "acceptable" in micropython. It's basically a whole different ecosystem to Python, negating a lot of the advantages of Python.
I assumed this was just PowerVR/imagination tech's raytracing patents expiring.

Feel free to educate me regarding how "it" works if you feel my opinion is in error. It seems unlikely that any system will constructed any time soon which doesn't involve onerous secret key distribution, is provably correct, doesn't allow someone to prove after the fact to a third party that they voted a certain way, is secure against insider and outside manipulation, can be verified in a way that an average person could understand. All properties of presently available paper voting solutions.
I remember a DOS (or early Windows) game like this. A top-down, 2D game for two players or 1 + CPU. There were no obstacles, but every time you moved through the background fluid, more fluid was created in your colour (purple / pink), and you could envelop the enemy player by 'swooshing' it around over them.

Can't remember the name...
This will mark me as uncool or whatever but why is HN annoying. I like it
> the only possible reason that a farmer can't charge more than $1.35 for a gallon of milk is that some other farmer is able to produce a gallon of milk for less than $1.35

Not necessarily - if you have demand for 300 units of milk and there are enough producers to match, then when demand halves, the producers are still producing 300 units of milk and paying for the costs to produce that amount of milk. To offset those costs as much as possible, they'll willingly momentarily sell under marginal cost - the production costs have already been spent anyways

I never understood the attraction of PIC in the face of ARM. The ecosystem seemed so much weaker in terms of compilers, libraries, and sheer variety of parts available.
Thanks for the share.. I was just reading about asynchronous io this weekend.
Elixir is great but it will have roughly have the same mind space as Ocaml, Haskell or other ML languages. It is very impractical to hire people for elixir, i can teach people lisp in a day if they know javascript or ruby because lisp supports imperative style aswell. Purely Functional approaches has its demerits most importantly the learning curve and unlearning from the OO and Imperative world. I feel gradual adaptation to functional approach like in lisp languages is better. Most modern lisp/schemes like Clojure/Racket are easier to teach and become productive in than Elixir. Elixir requires serious effort, i had put one month of serious effort to learn Elixir, meanwhile i learnt clojure basics in few hours.
If you enable Bitcode, each device will get their own binary though? Or does that only apply if they later change their architecture?

Yes. In many cases, comments help with understanding posts, and seeing value vs bullshit. Also, I sometimes find myself on HN, when researching problems, and it's comments and cited resources that are most useful.
There was a dialect called Business BASIC that was popular for business apps in the 1970s. It supported things like record-based file I/O (creating a navigational database), the creation of multiple concurrent tasks (on a 64k machine!), as well as exception handling in the form of additional params that specified which line numbers to branch to on error for all I/O operations.

Business BASIC was ported to mainstream PCs and other micros as the market for dedicated Business BASIC minicomputer systems waned. It still lives on today in the form of two dialects: ProvideX and BBj. And people are still writing/maintaining applications in it.
I'm quite excited about the different groups trying to reduce manufacturing costs of antimatter and use it for space propulsion.

Positron Dynamics is putting up a cube sat in the near future to demonstrate feasibility.

Generating antimatter is easier in space and using it instantly gets rid of storage hassles.

The amount needed for a trip to Mars would be around 10mg, the journey time would be measured in weeks.

Possibly the best hope there is for constant acceleration spacetravel.

I’ll state it here again, but if anyone reading this lives within a reasonable distance to an Alamo Drafthouse, it is absolutely worth it.

I live in Dallas where we’re fortunate to have a half dozen of them. They’re all great, the food is excellent, staff is great, and on and on and on. I love this place and I go at least once a month probably and more during busy months.

It’s worth it!

You are absolutely correct and I completely agree; this is part of what I wanted to get at. Google also uses this two-fold "data-gathering disguised as a service" methodology in its captchas -- as your reference to "capare" reminded me. :)
To continue the analogy: The amount of reachable fruit depends a lot on the availability of tools. That’s why we didn’t have computer science in the copper age. There have a lot of new tools been developed recently, eg deep learning, and new areas of expertise have been unlocked with it. One just has to figure out what kinds of fruit are reachable now.
Absolutely minimizing the data and details you leave behind is very good advice.

But I wonder how long - with state-of-the-art aggregation and correlation techniques - lying will be an effective strategy. You can say you are Peter, but if you at the same time accidentally and regularly give your position away from an address that only has an Anna living there (together with other Anna-specific data) you will be found out soon enough. And you also run the risk of an algorithm marking you as unreliable or prone to lying (and other misunderstandings about you).
For hydroponics, I've heard of lettuce being commercially grown, but nothing else - it's more expensive than just farming a large section of land.

And for automation, yes it is a threat, but often times more expensive than just paying cheap labor, which it seems the world won't be running out of in the short term
Yeah they can keep them. Worst nut.
You can lie about the birth date by picking something in the neighborhood and still be close enough to your real age to hit the creation path, per your comment, that complies with COPPA.

Moving from Canada to the US was a shock - in Canada, prescribing opioids was rare - but you could get codeine painkillers over the counter, but that was when things got really bad.... here, simple dental procedures were met with Percocets and Oxycontin...

The basic difference seems to be in Canada, you're a patient while in the US, you're a customer... and the docs don't want their customers to be in pain. That appears to be changing.

Not to be rude, but you are literally talking to someone who was in charge of this, looked at the graphs daily, and made the call when we went over the OTA limit on iOS. When I say multiple-apks are a large reason for the discrepancy, you should give me the benefit of the doubt. It's not the only reason mind you.

I apologize for the late reply. The idea for this response came to me just now as I was absently-minded scrolling through old comments, and I wanted to try expressing it. Don't feel obligated to respond.

I think we agree that individual humans are driven by a diverse set of incentives and motivations, some of which cause the pursuit financial gain, but many of which do not.

It seems that you are saying that a public company is an entity that purely seeks financial gain (at least, as its meta-objective -- e.g. it may take actions that it believes will increase profits in a rather indirect way, with direct monetary loss initially), and that non-monetary incentives are not a meaningful factor. Please correct me if I don't have that right.

Public companies are made up of people, so if your above argument is to hold, it requires that the non-monetary incentives driving those individuals are _utterly and completely_ suppressed, at least for any actions and decisions related to their work.

I can believe that the non-monetary incentives are _heavily_ suppressed by the company, but I don't think this suppression is so utterly effective such that those incentives should be entirely disregarded. I'm not sure how much weight we should place on these other factors, but it certainly seems that it usually won't be 0.
To put this in more context:

at the time there were 32 file servers, each with a 60 disk array attached. Thats almost 2000 spinny disks.

At that scale we'd expect about one failing disk every two weeks+. We were covered by a 24/7/365 4 hour warranty. This means that a replacement disk will appear within 4 hours, anytime of the year.

From what I understand the old disks are taken back, examined, refurbished and sent out again. I've heard that its often head alignmet, and or track setup issues that cause the most problems.

But yeah, there is waste....

+in practice we had a lot more disks than this, as we needed fast online backup. so we'd normally have at least two failed disks a week.
Why are RT cores so different than normal shader cores? What instructions/memory fetch does a ray trace operation do that couldn't be implemented as an added instruction set on the shader cores to navigate the volume tree?

From the article, the best I can see is the following, but can't that be solved with microcode or as an extra rendering pipeline stage?

> In comparison, traversing the BVH in shaders would require thousands of instruction slots per ray cast, all for testing against bounding box intersections in the BVH

I ask, because having more slightly larger general purpose cores seems better for traditional rendering and raytracing than dedicating all that die space to pure single-purpose RT cores.

This article contradicts itself in at least one significant way without providing a real explanation for the contradiction.

Early on the article claims "Apple tells CNET that it won't delete your movies, either. At least, not ones you've downloaded.". But that's not a useful answer because it doesn't provide any real security about one's downloaded works.

Later CNET says "We can't be sure what will will happen if Disney -- or any other content provider -- "recalls" a digital purchase, as a publisher did with an ebook of George Orwell's 1984 on Amazon back in 2009.".

Keep in mind that Amazon made a similar pledge to what Apple reportedly told CNET. As Richard Stallman rightly points out in https://stallman.org/amazon.html "In response to criticism, Amazon promised it would never do this again unless ordered to by the state, which I find not very comforting.". In other words, Amazon tacitly acknowledges it retains the power to do this again.

It's far more useful to examine the situation along the lines of which party retains what power over the user, or to look at how much freedom users have in the situation.

Therefore the real hinge here (which goes completely unaddressed in the CNET article) is software freedom (the freedom to run, inspect, share, and modify published computer software). If one uses free software to locate and read/play the work, then one has a chance to make sure that the free program won't betray their interests -- continuing to read/play the work at any time, for any reason, and do so without spying on or reporting the activity to others without explicit consent from the user.

But if one uses proprietary (nonfree, user-subjugating) software to access a downloaded copy of the work, one's access to the work is in jeopardy. One can't be certain that copy will be readable/playable through that proprietary software. Perhaps the proprietary software will delete that copy of the work (putting aside what's legal or, more importantly, ethical for the moment, it is worth noting that proprietors retain the technical power to do exactly this in most people's common use of media). Perhaps the proprietary software will report on the user's attempt to read/play the work thus notifying someone what's being read/played and from where.
Can anybody briefly describe how a 3x funding increase would change things from "may not be able to invent" to "[likely] to be able to be produced in the foreseeable future"? I'm very disappointed that news articles no longer hit on even the most fundamental questions like this. Instead articles now take a position (you should be in favor of donating money to [x,y,z]) and then go from there.

This seems to challenge belief. There are almost always rapidly diminishing returns on increasing allocation of resources once you reach a certain baseline. And almost is a weasel word there -- I can't think of anything where this is not true. Just like 50 programmers won't work 50 times faster than 1 programmer on a given task, 50 times the amount of money dedicated to a task will often provide far less than 50x the return. And the article's premise is suggesting not only a linear return on investment, but a largely exponential one.

Of course this all goes out the window when you're desperately understaffed or underfunded, but if $3 billion a year is anything remotely close to 'desperately underfunded' then it makes one wonder if that may be a product of waste and inefficiency than a lack of funding.
