To add to your comment about density of the transportation network itself, you also need housing/commercial density near those transit stops to feed people into the transportation network. Real estate developers aren't going to lead the charge in areas where housing/commercial density doesn't yet exist without an incentive (demographics, transit, etc.) and in the case of transportation density there is arguably no better incentive for developers because they can be guaranteed that people will "show up," en masse, at mass transit stops like moths to flame. Not hard to justify building at those locations (note that there is a difference, one I don't have the ability to quantify/source, between bus stops every block or two and light or heavy rail stops with the latter being much more compelling to the developer).

Specific to LA, here are a couple of projects where moths -> flame -> incentivized developers:

Data Lake to GPUs – BlazingSQL and RAPIDS Initial Benchmark
I'm unclear what you're asking for? The computer-supported peer-instruction phone app example is based on work by Eric Mazur at Harvard (physics; physics education research; peer instruction). The AI example is simply a generic computer-human process hybrid, taking the existing teacher/tutor task of productively managing student grouping and learning, and scaling it with computer-based monitoring and optimization.

Prior art? If your interest is in patents, my fuzzy understanding is Mazur regrettably took a familiar path. Unable to get follow-on research funding on the topic, he created a startup, with Harvard patent(s) (on what exactly I must of course avoid knowing) for table stakes and moat. The startup of course failed, and was acquired by a large dysfunctional education incumbent for the anticompetitive "value" of the patents. Leaving society arguably much worse off than if the original physics education research had never been funded at all.

It's my fear that the conjunction of education with computer-human hybrid processes, and with with AR/VR, given the regulatory capture of patent policy, and plummeting ordinary skill levels, is creating a toxic stew of patents that will profoundly impede innovation in education in the US for many years.

Isn’t that the intent behind the EU’s right to be forgotten?
I don't remember exactly where, but the option is in your (web-accessible) Netflix account settings, not on your PS4 specifically. I assume it applies everywhere.
I agree it should be done with caution and even more regulation. I disagree that securitizing mortgages was the absolute cause of the financial crisis.

I do think that the manner in which it was done and the disregard with which it was executed was the cause of the financial crisis. With banks offloading risky debt as if it were AAA to other institutions, all passing the buck to someone else making it someone else's problem until the bubble imploded and everything fell to pieces - like a giant Ponzi scheme.

I'm not saying that mislabeling wasn't fraudulent, it was. What I'm saying is that spreading the risk among your portfolio allowing those who need it to leverage lower interest rates is less predatory than forcing them to make interest payments they can't afford, thus keeping them in debt slavery longer.

You spend less time in debt slavery if you don't have exorbitant interest rates making up the bulk of your loan repayments... this is why countless times, I end up buying a new car rather than used, because when the interest payments and restrictive loan terms are taken into account, the monthly payments for a new truck aren't significantly different than those for a previously owned. Sure, the used truck at 9% will be paid off 2 years quicker, but more of my money is paid back towards the privilege of having the loan instead of paying for the cost of the truck.

I'm already paying that amount every month and I'm used to making those payments, would I rather pay off a used truck that I had to compromise on a whole bunch of features, or would I rather have the brand new truck with exactly the featureset I want at the same monthly rate, but for an extra couple of years?

I don't mind the extra couple of years payment to have the one I really want - especially given that my monthly payments for both well within my budget. I don't want to pay for the loan. I want to pay for the truck.

So that's the difference. Forcing someone to pay the higher interest rate means they can't have what they really need because they're paying more for the loan than they are for what they need. They could pay the same amount for a larger mortgage with lower interest rates and have the nicer home.

I guess this is a long winded way of saying that despite the mortgage lender's fraudulent and underhanded execution, there is a perspective here that's valid.
"Could you be thinking more of a "pure developer perspective" than "pure CS perspective" perhaps?"

Yes, sure. Julia is an interesting language, CS-wise. My only point, inasmuch as I had one, was that there are other languages out there that have those same features.

"If I want to get things done, I'd stick to Python for now though due to sheer momentum."

I tried python, because you're right, it has the momentum and is the obvious first choice for numerical computing after you've had your fill of Matlab. Unfortunately, for a lot of the code I write, speed matters. In large part I'm prototyping my own numerical methods, not totally relying on numpy/scipy. The last time I tried python for numerical code development I ended up with a routine that was two orders of magnitude slower than it needed to be. I rewrote the entire thing in Julia, with little to no effort towards optimizing it, and it was immediately 50x faster than python and within a factor of two of what I needed. I put a couple of days of effort into optimization and I got it down to 2-3x faster than required.

You could argue that I should have gotten better at optimizing python, and maybe you'd be right. I'm no python expert. But in my limited interaction with the python community, the answer to faster python seems to be, at the end of the day, to write the parts of the code you really need to be fast in C and call them with the python FFI. Which is what numpy does, if I understand correctly. Whereas I can write that same code directly in Julia and it's generally fast enough.

For a lot of use cases speed doesn't really matter. But for robotics (my field) or self driving cars or machine vision or a lot of other embedded applications, it does matter.
I would think that the performance difference between a 2013 and 2018 MBP would be significantly larger than the performance difference between a 2013 and 2015 MBP.

Having said that, MBP to MBP comparisons are not always apples to apples (sorry about the pun). You need to compare MBPs with CPUs from the same family as well.

Electron has its place, which is allowing web developers to make 'native' apps without learning new technology. When you are downloading any free software built on Electron, realize that it likely started as a labor of love that the person decided to open source or make available for free.

That said, large companies using Electron is what I don't get. You can't expect me to believe Slack doesn't have the resources to create an actual app for their product.
Slanted though it may be, Fox's reporting is generally about as on the level as their contemporaries, and their written articles are a notable step up from their tv coverage.

They've even received some praise from Sy Hearsh for having what he saw as one of the most promising investigative teams in the industry (I'll have to find the interview later today and update the comment with a link).

I do question the wikileaks rating, but wikileaks isn't a news site, and everything they publish ought to be a matter of 'buyer beware'.

I also question Microsoft's decision to include the plugin at all. I'd rather not have an arbiter of truth looking over my shoulders, reminding me what i should or shouldn't read.
Banks (almost?) never want to repo and own a property. In most situations the bank 1. spends a bunch of opex to work out / sell off the property, and 2. has to remit any excess to the borrower.

There are predatory operators known colloquially as “loan to own” guys, but they are usually unregulated and operating in the business world where the collateral value is less observable.

For a bank, I believe Other Real Estate Owned (OREO, the balance sheet category where foreclosure properties are carried) is always considered a black mark and a burden, dragging down ROA/ROE.
Kind of! They allow systems with slightly different clock rates to adjust. A system sending data nominally at 10 Gb/s can actually run slightly faster to a system running slightly slower b/c their timing bases (crystals) oscillate at slight different frequencies.

I'm fine with slower hardware, and agree in principle with what the article is saying, but not poor displays. The reason I pick a MacBook over a Thinkpad is because the screen quality is cash money compared to the 1080p on the stock T series. I just can't do 1080p anymore.

Also, you could solve this problem by just using a VM. If it really bothers you to have so much RAM and CPU, just spin up a 1401 in VirtualBox and use that for all your dev needs.
Charter schools are basically government subsidized private schools for "middle class" kids who live in resource poor public school districts. They are like magnet schools but they were opened up to private and for profit entities. Parents like them because they concentrate well motivated kids. Republicans like them because they will help bust unions. This will basically continue the current socioeconomic stratification we have.

We would do a lot better investing in intensive early childhood education, providing after school care as well as subsidizing 3 meals a day to our kids.

I wonder if this is typical end-of-cycle behavior:
1. Sub-prime is back
2. UK lenders announce mortgages where loan amount is set with reference to joint child and parental income
3. Other examples of frothiness welcome.

I wonder if banks get to see the end coming ahead of everyone else - but in order to meet business targets, have to relax lending requirements to keep the party going just a little bit longer.
It seems to me that you expect a lot from a short opinion piece written on a personal site.
I'm not so much talking about "me too" specifically, that said, I don't feel that minor tweaks to process or formula are deserving of another patent and many years of protections. And, as I said, I don't feel that there should be a single provider at all. The licensing for patents can be worked out, but imho if the sale of the drug required dual, independent sourcing as a requirement there would be at least some push downward on pricing.

> that it has withheld publishing information for questionable reasons

This is echoed quite a bit lately, I have not seen any evidence to support it. Is there any documented case where WikiLeaks withheld information? Is the criticism about the fact that they have a release schedule rather than always immediately publishing? They're a journalism group at the end of the day, don't they have a right to publish stories in a way that maximizes impact?
Actually, while I'm here—if anyone knows of a platform that has an outdated Netflix app without autoplay support, please let me know. I will buy hardware for this.

Is the package management story significantly worse for js/node than other languages or is it just a meme? If it actually does have more issues, why? Are the npm maintainers less rigorous than, maven central (for example)?

Java is lucky enough to have a lot of very solid Apache libraries built with enterprise money. Is the culture different for js and npm?
I don't disagree that descriptors like "extreme poverty" are inherently vague, but I think that's kind of the point - that regardless for where the exact line is, we can all agree there's some point where people are unambiguously in the world of "extreme poverty". For people in that world, we can easily pick out the hugest pain points in their struggle - lack of healthcare, lack of housing, and so on. And then, we can structurally change how these resources are distributed by society in a way such nobody will have to live without them.

That's really all the progressive agenda is, right? We recognize that having no healthcare at all (and the associated problems with that level of poverty) is immoral, so we want healthcare for all, even if we have to raise the marginal tax rate at the top level to do so (and so on).

I don't think there needs to be a formula for what constitutes "extreme poverty" to make poverty less painful for America.

Edit: or to put it another way, since most everyone agrees that going full communism is categorically a bad idea, partially socializing resources that can be considered a common good is a good alternative. We already do this with plenty of things, like the military, we're just looking to take it a step further where appropriate.
I don't think the US healthcare budget can't be improved. I just don't think the way to improve it is to eliminate it altogether to pay for a fraction of the US population to receive $12k handouts instead.

And the pensions budget is mostly spent on disbursing cash to people with the right social security number - precisely the thing you're advocating doing more of....

Ask HN: What is the product development process at your company/startup?
I work at a fast growing startup and if there is one thing that is certain it is change. Everything changes fast and everything and everyone needs to adapt. Part of that is the product development process (the process of creating software/product from ideation to execution).

I am wondering how other companies (established or growing) went about designing their process. For example:

- Discovery Phase: Ideation phase -> Validation phase -> Design phase -> Testing phase -> Debrief phase

- Backlog Refinement Phase

- Sprint phase
- Sprint planning
- Daily standups
- Code review phase
- Design review phase
- Sprint retrospective

- Code Deployment phase

Also what would be some of the best practices applied (what kind of code reviews sessions happen, CI/CD requirements, etc.)

Its an endemic problem in almost all industries that upward mobility means "management" despite it often being a completely divergent and esoteric skillset from the job you were hired on for, and often one that is less resource intensive to train for - learning good managerial skills can often be a weekend seminar, versus the years it takes to become competent in a companies codebase.

But of course the boss sets the salaries so thats where the money ends up going.
There is a similar line of thinking for audio engineers who do a final mix/master of music before it is sent off to radio, streaming platforms, etc.

After spending hundreds or thousands of dollars on expensive sound systems and professional speakers, engineers realized the average users listen to their music through inexpensive mediums. A cheap pair of headphones, a small bluetooth speaker, or even laptop speakers. They rarely listen to their music through mediums where the full audio spectrum is present, so in order for an engineer to get a mix that translates well across all mediums, they do their final mixes and tweaks on devices like a pair of apple earpods, or a more famous example, the Yamaha NS-10 [0].

The line of reasoning being: if you can get it to sound good on a basic speaker, it will sound great on high end systems, which is a win-win!

I vaguely recall a talk by Stefan Karpinsky where he mentions meeting one of the big names in compiler land (working on V8 or something) and they said Julia's JIT is just a lazily evaluated AOT compiler, and as a result much simpler than the JITs typically seen in other languages.
It's not an issue of "clogged" vs "not clogged" but "more clogged" vs "less clogged" and "have an option to bypass gridlock" vs "don't have an option". You have to compare to the counterfactual. Yes, transit-friendly cities have clogged freeways, but it's much better than it would be if they didn't have the trains at all -- see what happens whenever BART shuts down.
I think that's just the Docker for Mac client (and Hypervisor.framework). I think the disk I/O performance was bad, the last time I used it was for Node.js/Postgres about two years ago. I was able to really speed up the integration test suite by disabling fsync for Postgres.

If you were running native Linux it should be a lot faster.
Interesting. Thanks for posting this, it really helped me understand what the issue is.
Your reasoning and the conclusion resonates a lot with my own findings for a project that we tried to bootstrap. GCP's GKE and Istio integration are becoming more compelling to consider them for containerized workloads. EKS isn't quite there. One of the things we are struggling with is finding a qualified partner who can help us build our new project on GCP. We don't have a mature infrastructure team and while we try to bootstrap one, we would like to rely on partners to help us move the needle. Even partners in GCP premier list don't have case studies of migrating monoliths to GCP. Most of them talk about GSuite migration which isn't quite the same. AWS wins this battle. They have far more mature partners with better track record and thought leadership. I wonder if you see this the same way. Maybe partnership is not crucial for you? Some insights from the community would help.
Holy Traits are used extensively in the standard library (for iteration and collections among other things).
Has any metropolitan area ever gotten car usage to meaningfully decrease? Yeah there are cities that have high (and increasing) transit ridership, but they never had high car ridership.

Once someone starts tasting driving, they're hooked on it. The best bet for transit would be to market to the next generation.

This is one thing I thoroughly miss from Perl's CPAN: modules there have extensive testing, thanks to the CPAN Testers Network. It's not just a green/red badge but reporting is for the version triplet { module version, perl version, OS version }. I really wish NPM did the same.
