If you had vision that bad, the State of California would not let you get a drivers license, they require at least one of your eyes to be 20/40. Anyway, the point of the GP is that the brain isn't the only piece of wetware doing image processing, but more to the point the current state of the art CV really is not up to the task.

And it really doesn't seem like it's going to be there anytime soon.
Rust is a really fantastic language but trivial examples can be misleading. We run a Rust app in production at ChartMogul.

Real life Rust business logic is much, much gnarlier than in a GCed language like JS. You need to manage memory so you need to deal with references and deref, lifetimes, Box, Cell, ARC etc.

For an open source example of what kind of complexity arises in real life check out crates.io:

Lots of misinformation in this article. My favorite one is "Plasma is dead". Meanwhile Plasma MVP was just demoed at Devcon last month...
Yeah, I mean I see this article as a not-so-subtle middle finger to computer science elitists, so I don't think backlash was unexpected (on the contrary, welcomed).

React itself represents a shift in webdev thought where, instead of desperately trying to establish itself as a "respectable" programming field (see: any Google web technology), it instead focuses on being as accessible as possible and embraces the populist nature of the web. This article is just an extension of that ideology.

And, as you've indicated, anyone who would be horrified by that ideology probably is already horrified by the web to begin with.
the decentralized nature of the e911 system is what made it fault tolerant. moving these systems to a more centralized topology is probably going to cost them alot of money in downtime and fines from the FCC in the long run...
And then you repeat endlessly education inequalities.
This could reduce the cost of making silicon chips, and make it easier as well.
That doesn’t address solar and wind being drastically cheaper than nuclear fission. It would be wasteful to continue to poor dollars into fission at this point, versus scaling up renewables and battery manufacturing further.

Whether the race is rigged is irrelevant; the race is over.
<- is a comprehension, its like a for loop.

-> is like for everything else like case and cond

= is bind operator and is only used when you want to pattern match
I don't think I understand your point. If you believe the headline and think you're more likely to get fired when you're 50+, isn't that a sign that you might have no choice but to "sell your best years" (presumably the <50 ones), if anything?

> Make sure you live a life and have a plan so that when you get fired ... you can still live a good life.

Well yeah, I think just about everyone would like to have both a great life and financial security. The problem is that those two goals can be at odds for some/most people.
This is very common because of the way transport is built and sold.

Doing real traffic engineering where shared risk link groups do not exist for the active and standby links is a lot of work and, moreover, is hard to keep working as operators change their networks (for maintenance, for other reasons).

On top of the basic difficulty, there are other issues - layering makes this opaque, the service providers have become completely de-skilled, the business model for MPLS is getting killed by Over-The-Top providers who pretend they can give you equivalent service using multiple links and IPSEC tunnels. And so on.

When reading this I think of my deep knowledge of TCP (especially the pain points) and yet it is "The Internet" for the past while. Compared to simpler protocols like Delta-T and later/better protocols like XTP, TCP still "won" for a variety of reasons (adoption, good enough, numbers of implementation, hardware implementation, etc)

There are a couple reasons I think Ethereum might prevail over bitcoin:

* Vitalik is young and "all in", god willing he will have many decades to refine and improve Ethereum. Think Linus and Linux versus the cabal of Bitcoin and BSD core leadership.

* Most of the criticism in this article are things that have slipped committed or expected dates. The community is aware of the problems and is looking forward to fixing them despite it taking longer than expected. It's ok to be wrong and off on dates if you get it right "just in time" which is only obvious after the fact.

All in all, Bitcoin might be BSD and Ethereum might be Linux. BSD was technically better for a decade, but Linux had the central leadership of a young Linus and scaled better in adding new developers and corporate users into the mix at the right time. That seemed to matter more than quality, stability, and longevity of governance at least up until now.

It's perfectly valid to point out the technical flaws and remind people they missed their commitments. But I'd caution against making financial decisions with too much weight on that alone, which would be about as effective as making them on the expected good will of the community of a cryptocoin :)
Im new (1yr or so) to elixir, never really believed in dialyzer, but a few weeks ago I noticed my vscode started dialyzing my code in real time and it's caught several errors that would have been hard to catch, and whatever vscode plugin I'm using makes it hard to not write typespecs.

Bell curves are a lie though. What if you taught well and everyone understood your lesson and they fared well on the test ? The French way of grading without a curve is much better in that aspect.

The edit button is a wonderful tool.

Besides, the fact that I can drive my car relying primarily on two eyes and a brain suggests that it must be possible to extract and process the information to drive a car with stereo vision, and without LIDAR. LIDAR may become cheap and small enough that it should be added purely from a safety perspective - more better information is better. However, I think plenty of experts would agree that theoretically it is possible without.

Here are some experts that think it works without LIDAR, so you may wish to edit “every”. https://arxiv.org/pdf/1708.09839.pdf
No, no, no... you got it all wrong... They should be using COBOL...
If every condition is important to the business, as is implied in this case, it would be very valuable to have tests to cover them.
Hilarious that you posted a clip from Uncorked as some form of evidence, because no one has ever lied on reality tv to make things more dramatic.
I'm not sure what your argument was? But I'll reply with a few points.

Bitcoin mining depends on finding a hash that starts with a whole bunch of zeros, which is more or less equivalent to being just close enough to a jesus that you can sell it for money.

Joining a mining pool gets you a relatively fixed payout, counteracting the lottery nature. You'd only have to burn one box of matches to get a guaranteed payout of 300/730000 of a jesus match.

Yes it's still a waste of power.
Redux, IMO is a beautiful state management library.

Were you following Dan’s tutorial on Redux? Because that is a beautifully made tutorial as well. (https://egghead.io/redux)

If you have tried to build a substantially big app with React alone, you will find yourself lost in passing down the props and callbacks and hoisting variables and what not. You definitely need a state management library where you can CRUD from all your React components. Thats where Redux/Mobx comes into picture, unless you want to write a new one.

I agree that Redux needs a lot of boilerplate though.
What you're saying here goes against any reasonable macroeconomic theory.

Deflation causes spending to stop because people hoard money, as spending stops, economies dry up, and voila... economic stagnation at best. But no one without a formal education is Economics is likely to even be remotely aware of that.

Inflation, and Keynesian economics, have empirically served the world quite well. The government's and social policies that go with them not so consistent BUT and this is the important part-- Economics doesn't give a fuck. Inflation is a tool to allow an economy to grow, deflation is a tool to shrink an economy.

Economics is the science of resource management, it's not an opinion. Your opinion is as depressing to me as it is empirically wrong.
Some specific examples of real deadlines I'm thinking of include: Giving a talk at a conference, submitting a bid for a contract, anything involving the court system (continuances are by no means guaranteed), a product launch with a firm already publicized date, or even worse, a product launch with a firm already publicized date and dozens of external partners (this is what I do at work).

In most of these cases you can't really scale back; you're either ready by the deadline or you're not, with catastrophic consequences for not being ready.

So that plan is save money in your post tax accounts (non retirement) and keep some insulated from the market fluctuations?

No offense op, but if you have a clear idea, it’s better to communicate clearly. Why play riddles and not flat out state what you’re trying to state?
All of that started with a mod for Quake 2 called Action Quake. You could break your legs by falling or bleed out, and had to bandage, that kind of thing. It was the predecessor to Counter Strike, which in turn birthed a lot of modern shooter mechanics.

There is a HUGE market in China for counterfeit products. In China, even Mercedes-Benz you buy might be entirely counterfeit! Until recent years, these fake products didn't leave China to come to US shores. Now these merchants are simply creating web of LLCs and have Amazon ship it off their crap on Prime. At least dozen product categories were reported as counterfeits in various reviews like Duracells, headlamp, bulbs, USB cables, board games, GoPro like cameras, razor blades etc. I wish Amazon at least made it compulsory to disclose "Made in XYZ" in product description (isn't that a law anyway?).
Yes sorry I was being inexplicit about variable rebinding. I'm used to Julia where variable refers to the lexical form.... Identifier? And not to the actual underlying data, which is called the value.

I'll write up my credo linter and see if you like it.

Your guard idea is pretty good, but I would appreciate it even more if those guards existed in dev and test and got yanked in prod.
I do a lot of work where I rapidly mature business functions/processes, generally related to analytics and data work. I basically fill a self-supporting business role, while handling the technical needs until the processes fully mature.

A core concern of mid/upper level management is sustainability, reproducibility, and maintainability of processes. The CTO wanted a format that could be reliabily reproduced by the skill sets that were staffed, even if the report itself was less robust than the Data Studio version. By introducing a new capability to a client, the CTO is in a bind to either adjust staffing to ensure deliverability of that capability or potentially risk losing a client if they ever have to switch back to the previous reporting after having elevated the clients expectations.

And the issue expands beyond that one client. It can potentially disrupt the expectations of other clients, and shift internal demand away from the types of reports your existing staff are capable of producing. And that's a huge can of worms since the demand may shift faster than attrition, leaving the CTO in the uncomfortable spot of having an existing staff with a rapidly dwindling internal demand and yet still needing to aggressively hire for the newer skillset.

If it had been used internally, rather than being exposed to the client, then it probably would have been received better by the CTO.

A technical analogy would be the CTO learning that a manager had approved exposing an unofficial API to important external users, and that the users loved it. So then you either piss the users off by taking it away and shifting them back to the cruddy old official API, or suddenly have a need to put resources behind ensuring that unofficial API is up to snuff and matches the same SLA with your official one.
Love this initiative. It's absolutely valid to plant a flag at the extreme end of the standards-vs-featureful spectrum.

Good.

Unemployment is at a local minimum for the last couple of decades. Schools have to exist and teachers leaving raises demand for teachers so schools will actually have to compete, maybe a mass exodus will get the shitty school situation in the US fixed a little bit.

The most powerful form of protest is to leave for something better.

- Less punctuation?

- Shift-indentation blocks?

- GC or not to GC?

- Bare-metal executables / static libs?

- Opt-in duck-typing and mandatory interfaces?

- Capabilities?

Yup. It does narrow it down pretty good. You know it’s true or not true. Nothing else is probably true.
Energy production is heavily regulated and centralized to a few entities. Very much like financial institutions.

It's highly unlikely that the free market somehow sorts this out in the future, considering that it's the free market that gave rise to these power law distributions to begin with.
I dont think it is so easy. Subduction zones have what are called accretionary prisms, which are basically sediment that is sloughed off the top of the subducting plate. Thus, if you want the nuclear waste to be subducted, you have to bury it deep enough, though I can't say quite how far - given the scale of the crust, I'd say you're looking at something on the order of miles at least. Which is extra challenging considering subduction zones are already under thousands of feet of ocean.
Wine might be a better comparison (at least a Rolls and a Toyota look different). Many could tell the difference pretty well between a $5 and $20 bottle (hint: the $20 one is the one not loaded with sugar), but not a whole lot of people can tell the difference between a $20 bottle and a $200 bottle. The law of diminishing returns kicks in pretty quick with both wine and audio. I think with audio once you’re in over a few hundred bucks for your set that wall comes up pretty quickly.
This is scary. I love and hate C, been using it almost 40 years. Its use seems more and more like juggling razor blades, wishing not to get cut but still always wondering when it will happen next.

Rust, Pony, Crystal, Go, Elixir, Haskell, OCaml, Lisp, Clojure have their merits to address most of C's shortcomings, offer much higher levels of abstraction (productivity) and provide these features that didn't yet exist when C grew up. Languages were mostly built bottom-up.

But really, C is often used as a portable-ish lingua franca, along with similar but different: JVM bytecode and LLVM IR, for writing nearer to bare metal (native assembly or runtime).

Can the mods remove this inane clickbait? How is this tech related or anything but political flamebait ?
It's not about copyright infringement. The problem is that counterfeits are typically sold at same price and more often than not experience is severely degraded. I personally have lost several hundreds of dollars worth of gadgets due to counterfeit duracells. Most importantly customer is being lied about what they are actually sold.
Princeton doesn’t provide any better instruction than a good state school.

What it provides is a circle of friends for your son or daughter that come from a different socioeconomic class. Which will allow your kids to operate smoothly in that class when they get out of college.

Sure PHP+Ajax still works, knock yourself out using that approach if you want. I won’t want to maintain your code, but feel free.

While I don’t disagree with the general notion that old stuff still works and new stuff is not necessarily better, this notion is incredibly well-worn around these parts. It really would be nice if people stopped driving it into the ground pretending it’s an interesting or original or contrarian point.

What I do find interesting is one of the replies by someone saying they quit webdev back in the PHP+ajax days, precisely because they found that approach so much less simple than it is often claimed to be. That’s an actual interesting point! But we don’t want to talk about that, we want to talk about “JS devs love everything shiny that came out 3 days ago.”
<- is used for with as well and that is not a comprehension, and in feel way more like an = pattern match. -> is used in lambdas, which is kind of like case (but not cond).
I had a professor who taught algebra and pedagogy of math in local university. He has a nice scheme for grades (1 to 5 in Russia are F to A respectively): each lecture except the first starts with 3-5 minute test on previous topics, marks for working at practice hours and final exam. The grade was calculated as an average of avg(tests)+avg(practice)+exam, so you have to work throughout the whole semester or you won't have a chance for C or higher which is a minimum to pass.

I'm not saying that it's completely bad, but with Bitcoin the devs work really hard to improve the software to make sure that the time for full resync doesn't grow too much, and that it can run on an average laptop that has SSD.

The biggest problem with the fast sync is that sometimes when Ethereum node gets stuck, the devs just suggest to do a new fast sync, which - in my opinion - requires enourmous amount of trust in the developers. Hard forks also require a lot of trust, as old software can't be run side-by-side with new software to validate the blockchain.
I couldn't find other IDEs that fulfill my need for remote C/C++ development (not just debugging). Maybe Eclipse has that feature as well, but the last time I tried it required me to install Java on the remote machine and start the server by myself, while in Netbeans everything works out of the box and it copies the server to the remote for you (using scp I think). Code analysis is superb, remote git/svn works, I get to browse the function call graph etc.

Then one time last year, VS Code was hyping, and I boarded the hype train. C/C++ seems to work... but not so well for my needs. There is no remote git, it uses your computer's compiler for parsing (I had it use WSL's gcc). Everytime I search for howtos of remote C for VS Code, all I see are answers where they ask you back, if you have git why aren't you developing on your computer? Well there's the in-house build system as well, which I don't think I can replicate well on my PC.

Too bad C/C++ is no longer an official shipped feature of Netbeans since Apache, but the installable plugin still works well so I have no complaints.
Nothing as complete that I know of. It isn’t crazy to use Emacs just for Org Mode. At least check under the hood and see what you think some time. I know some vim users that use Emacs solely for Org :)
