Maven/Ivy/SBT/Gradle/etc. Are a lot older than NPM. They solved a problem that wasn't well solved before. They're certainly not perfect, but I'm not sure NPM would be where it is today if we as developers hadn't learned from what came before it.

Sure they could be better, but there is a very large community relying on them, and the community is largely pre-complied code with different requirements from node.
If my metric is value provided by software running in production I can't see Node overtaking 20 years of JAVA code by this time next year.
What are the numbers for Cab Drivers? They should've listed that. I'm always skeptical of people pointing out the dirt of their competition when they have their own dirt to deal with.
I don't know why is everybody so much against the driverless cars project.

I think it's at least partly because many people think that truly autonomous driver-less cars are much further away than they seem. (Disclaimer: put me in this camp). That is, getting 90% of the way to a truly driver-less car is hard enough... but it's the second 90% that really kills ya.

Also, assuming driver-less cars do become a "thing", there's no particular reason to think that Uber will perfect them to such a degree that gives them any kind of competitive advantage. In the end, (as this theory goes), car companies will still be the people making cars in the future, and if Uber wants driver-less cars, they will just buy them from GM, Tesla, Toyota, Mercedes or whoever.
Popcorn Linux main idea started when trying to run Barrelfish OS (from ETHZ) we asked ourselfs "can I apply the same ideas to Linux"? Then we ended up in taking a somewhat different route in terms of system design for different reasons, some were technical. My personal perspective on the project was to try to understand if I can power up and down heterogeneous cores at any time, scaling indefinitely in the numbers of cores ... I changed that idea a little bit since I started the project (2012).
The current version of Popcorn Linux supports aarch64 + x86_64. Popcorn Linux runs only on OS-capable processors (no GPUs, no FPGAs). The kernel is not split up. You run different instances of the kernel on different ISA processors - one kernel per processor island (that is a set of processor cores with homogeneous characteristics). When a kernel boots up, if it is not the first one, it will join the community of Popcorn kernels. Operating system services are distributed, therefore things like memory are globally managed.
An applications to run among kernels must be compiled with the Popcorn Linux toolchain, and must be executed inside the Popcorn namespace (just an additional Linux namespace), in which the applications can see all the available memory and CPU cores. When your applications is in the namespace the only thing that it has to do is to call sched_setaffinity to migrate to another core - as easy as POSIX/SMP. You can migrate between different ISA at any point in the code (there is no limitation such as in offloading, that you have to go back as soon as the offloaded function is finished) - this is thanks to the stack rewriter (see below).
The current way Popcorn compiles an application to be run on aarch64 + x86_64 is to produce 2 binaries, one for aarch64 and one for x86_64. For now, the compiler toolchain is modified to align all symbols in each binary at the same address, and all data types have the same sizes; all alignments and paddings are forced the same way. For this reason we used musl, and yes, you need to recompile each library (although this is not strictly necessary in some cases). The executable is statically linked. The operating system cannot cross-ISA migrate your application at arbitrary points, the migration should be explicit in the code itself (but we added some OS-suggested migration, at automatically placed migration points). (If you want to cross-ISA migrate with OS control, you need emulation until a valid migration point, you can check the work from Venkat + Tullsen.) Finally, because the executable code of different ISAs sees the address space identically there is no need of state transformation during migration - this enables the developer to migrate a single thread, or a subset of threads of your application. The only thing that Popcorn transforms during cross-ISA migration is the stack, thanks to Rob that wrote the stack transformation routine. We decided to do not implement a single stack layout because we believed that the current stack ABI is optimized for performance, but as far as I remember we never tested the alternative option.
There is beauty in transitory experiences too most certainly! The unseen rainbow has beauty, but as a human I like to think I am more than a blink of a cosmic eye.

>I think it must be a totally alien, or even irritating, idea to a bunch who expects to paid enormous sum of money because they have done a crash course in JavaScript spanning a month and claims to be able to build websites that can "deliver value" to the business..

What's funny is that some of them are actually being paid enormous sums of money for very little skill investment.

So in light of that, programming is apparently not a field that expects you to master anything before your salary is maximized.
Research on ground truth/back testing
Looking for links, papers, thoughts on how ground truth fits into model development for reporting current periods or forecasting. Applications to financial markets/hedge funds are the most 'obvious,' but need not be constrained.

For example, if one wants to estimate earnings at Best Buy (a la 4square), foot traffic data from their SDK doesn't represent 100% of the visitors, so to better train models it is important to know what percentage of the population they are sampling. Models need to be calibrated against a ground truth, an indisputable source, and this is likely doesn't come from the retailer. In short, having ~24 months of historical and ground truth data can establish sufficient confidence to make forecasts/estimates.

Another example is estimating storm surge/wind patterns. 30 years of historical/ground truth is required for insurance purposes (not legally required, but establishes enough statistical confidence).

I'm looking for papers, thoughts, directions, etc.... from various industries/application areas to understand the relationship between historical data, ground truth and accuracy/confidence.
> automate the job

This is never a bad thing. The only bad thing is if your society doesn't account for the potential of automation and just leaves the unemployable destitute. But that is a political problem, not an economic one - being able to produce without any labor is one of the greatest accomplishments of economic development you can possibly have.

It does reflect that, in most western countries (and the US in particular) we have a glass house for an economy, propped up in large part by bullshit jobs that exist to satisfy the broader markets demand for comprehensive employment of citizens, and if you throw a pebble in that lake the ripples could break the dam holding a huge portion of the US workforce in employment right now.

Bezos is close to being the richest man recognized by western institutions (tyrants around the world probably control more assets, but can't utilize them on demand) and has the potential to spearhead the social and political changes necessary to adapt to the changing economic reality nobody wants to acknowledge, and that his company is near the forefront of bringing about. But that isn't particularly a way to spend money - it is more that he will hold the respect of oligarchs and politicians the world over and might be able to persuade some of them, if he were so persuaded himself, that like global warming this is not a can to just kick indefinitely down the road until overnight you see 50% unemployment and start seeing public hangings of the elite come back into vogue.
The Wonkavator is real: ThyssenKrupp unveils its maglev elevator
I gave up on Clojure despite spending a lot of hobby time on it and moved to Scala because it's simply a much easier language to sell to other engineers and management.

For me the C/C++ was a minor issue since if you're going to the trouble to do it on the JVM you may as well build that part in Java.
That is some great sourdough bread by the way!
Solution to shrink digital data storage
Very nice! I feel this space is under-developped. Luna reminds me a lot of Apple's Quartz Composer.

Visually representing anything complex is an immense challenge, but just like code is broken down into units (files/functions/whatever), a visual tool that can provide a fractal-like representation of a system would be awesome.

(I'm looking to dig deeper in this space for some pet projects.)
$1.5M Contest for Algorithms to Identify Concealed Items in Body Scanner Images
I tested it also for inclusion into cperl to replace the horrible old spencer regex code with longjmp for logical control and double parsing, and came to my conclusions. Rust's will get better eventually, but PCRE2 also gets better every week. That time PCRE2 was a bit faster, and supported more features. And it has a JIT. Only Hyperscan, PCRE2 and sregex have a JIT.

I haven't checked Rust's feature list, sorry. I ruled it out for serious usage very early, and it's still evolving.

Captures are very important for us. Same as UTF8.
There was once the idea to switch to a limited engine like RE2 after the first scan of the regex when it doesn't do backtracking. But then I would switch to Hyperscan instead, which has the best compiler, besides having a very good SIMD optimized runtime.

I suppose the words "pyramid scheme" has been mentioned before... hah, you gotta love the way technology does it, shall we call it Pyramid Scheme 2.0? Promise everyone profits, investors and workers alike, but scam the workers, and maybe there'll be profit for the investors, somewhere in the future.
It's clear enough. You're comment seems to be the only one confused about the point I make. We have some wiggle room in terms of population capacity - it's not that difficult a concept.
Interesting how you're misstating the rights attempts to oppress other people as "traditional values" or the courts protecting minorities as overturning the will of the people; it's easy to dress up bad behavior from the right in vague accusations against the left to deflect from the problem that is actually the right just being awful.

> Attempts to shut down Chick-fil-A in various states.

That's what happens when come out publicly as a pro-oppression organization, you're going to get blow-back from those trying to escape said oppression; this is hardly surprising or unwarranted. There's no reason a restaurant needed to take an anti-gay stance, crying about those actions having consequences is just silly.

> There have never been any olive branches extended by the left.

That's simply so untrue one can't even take it seriously. Obama continually attempted to work with the right so much so that one of the biggest critiques from his own party was stop trying to cooperate with them when they're doing nothing but obstructing anyway. He even passed a Republican health care law in a failed attempt to get bipartisan support on the issue.

> And even when the republicans own congress they somehow have to cede control to the democrat (see Obama years for reference).

They did no such thing, they obstructed for 6 years straight, they didn't cede anything. They filibustered so much they quite literally broke the government and started a new era of "no cooperation at all" that we're going to be paying for for the rest of our lives.

You're right, the "right" has given up; they've given up any connection to reality and an awareness of their own behavior and how awful it is. Oppression doesn't simply become acceptable because you label it "traditional values".
C doesn't let you have destructors that automatically clean up whatever got initialised in the Init method (if it was called), but C++ does.
Large scale short term programs can be very harmful though, e.g. Bezos shows up and gives everyone shoes and clothes, putting every shoe/clothing manufacturer (except the one he bought the shoes/clothes from) out of business, then when things have gotten better there's only one place to get shoes and clothes.

This isn't going to stop me from helping out people I meet and see in need, but as a large scale program it is (at least long term) harmful.
>Constructive mathematicians believe the reals exists.

I think when people mention the "reals" they are usually referring to the uncountable reals, which you can't construct, compute, name, or know:

https://arxiv.org/abs/math/0404335

...(maybe skip to chapter 5 to get to the meat of it). So constructivists don't believe in those types of numbers, and so get "choice" as a theorem instead of an axiom.
Those are really wonderful benches.

Well gold also has little intrinsic value. Of course, it has uses like in the manufacture of technology, but most gold is used for making useless shit into shiny useless shit. Crypto has uses, too though. Such as facilitating payments, DLT, etc.

All value is assigned. So, what then, besides traditional consensus, makes gold 'intrinsically valuable' without also making cryptocurrencies intrinsically valuable?
Except everybody hates Status for their terribly executed ICO which basically DoS'd the whole Ethereum network.

Square NYC is hiring
If we as a nation are going to be as opposed to unions and collective bargaining then some other mechanism needs to be in place to give labor some pricing power. The tax on labor is greater than the tax on capital. The pricing power for low skilled jobs is clearly heavily tilted in favor of employers. At some point, where we are headed maybe slavery will make a comeback.

Since I have no interest in seeing them survive, I'd take a the Bob Nardelli/Melissa Meyer approach of guaranteeing a nice golden parachute for myself, then drive the company over the cliff, and collect the payout on the way out the door.

Or, give up on the model of turning drivers into serfs for the benefit of privileged hipsters and focus on more mass-transit solutions.

I don't use IE, but I don't use Chrome either and refuse to use Chrome. Why I refuse to use Chrome isn't the point of this response, the point is there are reasons why I refuse to run Chrome and if you make it so your site is only accessible via Chrome then I won't be visiting your site.

What I just said about Chrome could be said for any browser, a lot of people have different reasons for not running certain browsers on their system. To generalize it's a bad idea to make your site accessible only via a specific browser.

They're currently being investigated by the Justice Department and fired dozens of people over sexual harassment. They also maybe knowingly stole self-driving tech. Seems like a few big deals.

And those are just the bigger issues, there are numerous issues with local municipalities and also issues with driver quality (someone in my state was raped by a driver who has since fled the country) and workforce satisfaction.

There are a series of issues that will be problematic for them as they approach the need for more funding. If they aren't triaged now they're going to have bigger issues in the near future.

Honestly this is the smartest thing they've done in a while.

It does, and it can be, but in situations where it matters, the static create function typically returns a value from a preallocated pool of memory, so objects are all contiguous and cache friendly.

If this is true if uber, that it has no path to profitability, isn't it also true of ubers competitors?

A lot of Uber's costs to date have been proving that ride-sharing is a thing that consumers want to do (market education) and that governments don't want to stop (lobbying). Their competition get the benefit of that Uber's investment in those things for free, so it might be the case that Uber will fail and their competition won't.

That's by no means saying it's definitely the case, but being the first mover has downsides as well as advantages.

You are exactly right. But who said that strawberries should be inexpensive and found in every fridge in America? What you have just acknowledged is that strawberries are not cheap. They should not be cheap.

The real danger here is not that Americans will be deprived of strawberries. The danger is that some American who does not actually harvest strawberries will not be able to profit so much from strawberries. Their business will be in jeopardy. It is obviously bad for America when we drive businesses out of business. American business people need to be able to have somebody else do all the work very cheaply so that the American business person can profit.

If nobody values your product enough to pay its true costs, the answer is to reduce costs by having somebody else work cheaper. If the free market doesn't support cheaper labor costs, you need to use some other method to reduce labor costs. Wielding control of immigration status is one tool to incent cheaper labor.

> It depends on scale and the skills available to you.

Skills -- yes. Scale? That's kind of the point, nowadays. You don't need a large staff to accomplish scale.

> I doubt it's the cause of their issues.

Their eng/ops approach wasn't the cause of any business issues, AFAIK. That's why my comment is directed around what happens when business performance suffers -- you start looking for cost reductions.
I think both are true. Uber paved the way to significant improvements in taxi-ish services. Even traditional taxi services have bumped up their game in the face of actual competition. If at the end of all this we just wind up with Lyft, Uber still deserves some credit there.

With all that being said, I probably won't be happy with the outcome of the lawsuits surrounding the shenanigans either. What will likely happen is Uber will get some hefty fines. But the people who will pay those fines are Uber's customers (and potentially investors). The more focus we can put on criminal and civil penalties for the individuals involved, even if that meant literally every person in the company, the better.
