> FWIW, I don't see a 10 second delay. I see a delay of roughly 2.5 seconds (Firefox; Chrome is a bit slower), followed by a Unity splash screen (which you can disable once you buy a license). But the delay obviously depends on the speed of the user's machine and network.

I don't know if it's barely downloading. Looking at the Dev tools, it looks like it downloads assets, then takes a good while to parse them.

> Even if some systems, like physics, can be removed if not used, Unity is still a full-blown 3D game engine. It can of course also do 2D, but it'll almost inevitably have a higher overhead than a dedicated 2D WebGL engine.

So, there's no way to not "load" the 3D component or other components besides physics, or is there?
Ah, I'm behind the times. Thanks!
Relate 'karma' to the ability to post at all?

More karma, more posting; less karma, less posting. Everyone starts every month/week/day with only so much, no roll-over per timeframe. Modify it so that 'popular' threads cost more to post in. You can give karma to others too via the upvote and take it away with a downvote, but still no roll-over. Troll/shill accounts would still get upped around en masse, but less so and it would be 'easier' for mods to tell. (I'm sure you can model this without too much effort vis a vi prisoner's dilemma). You'd have to pick and choose which to comment in. Posting content would work similarly, but a slight mod to the cost to posting.

Is the drilling mud pumped down to create that pressure then, or is it naturally present? Or one pumps water down to turn the grit into a slurry?
Last time I was in Shanghai a couple years ago, it seemed like a good 20% of the motorbikes on the street were actually electric bikes. A dizzying variety of electric bikes too. I've yet to seen that kind of uptake of electric bikes in Vietnam or Thailand. Would be great if most motorbikes were electric, and cars too.
I call BS. You're just hyper sensitive to it now. There is absolutely no way FB is able to spy on people through their phone mics at this time.
I'm pretty sure folks generally mean highly processed foods - high fructose corn syrup, for example, and some modern vegetable fats. This is pretty vague, of course. And sometimes folks include older methods such as making sausages and bacon to it. They could mean something like mycoprotein (quorn branded meat replacements) or pea protein based meat replacements (Beyond meat, for example), though those hardly seem to be in the same sort of category even though they seem pretty processed.

The question is why I bring up the processing that we make good use of, actually. :)
That book indeed is really really good. Though i have one feedback, they should have solutions to "Extra problems" they have at the end of chapter (maybe separately). Have been stuck at closures for couple of days now, where you are supposed to implement your own cacher with hashmap.
How does this compare to relying on Parameter Store if you're in AWS?
Webassembly (and JavaScript) are single-threaded. The platform has web workers, but they are more like processes since they mostly don't share data.

There do seem to be some proposals to add threads, though. Also, it's possible (but hard) to build cooperative multithreading on top of it; apparently Go is going to do that.

Can you please elaborate more how to be a producer rather than just a consumer in maths? Advice like to do more maths rather than read it is clear and a regular undergrad can follow it. Producing in maths sounds like writing papers to me that I can hardly imaging as an undergrad student. It is actually a problem for me as for a software engineer: in programming I can produce rather early and it creates a motivational feedback plus helps learing things better. With maths I cannot get the feeling of creating anything, the only pleasure is in solving problems from books.
Coltrane Pitch Diagrams: Wrapping notes around a torus
My small brush with this: back in the summer of 1990, I did a summer internship with Doug Lea who led the JSR 166 group that led to java.util.concurrent. My work was on a concurrency library for a parallel computer called the Encore Multimax
Yeah this dropped off the front page very quickly. Came back to find the comments probably half an hour after viewing it at the 5th spot, but it was no longer there.

It's obvious why it's done but always serves as a reminder of HNs lack of impartiality on submissions.
Nice to see PKCE included, though no mention of the state param. Also not a great experience to log in via a web browser, and not really more secure given a malicious app could just fake a browser. Magic links with PKCE + app-site association would be better.

Some tips:

1. Don't build your own OAuth 2 server.

And if you're just doing auth for your own apps - not providing auth services for third parties to integrate with - I wouldn't suggest using OAuth at all. It's much more complicated and you're much more likely to make mistakes.

It isn't a bad idea to (carefully) read and learn from the principles of the OAuth 2 spec in order to make your own auth services, but I'd generally suggest avoiding making an OAuth server by hand unless you are very experienced in doing this. There are a lot of silly mistakes you can make due to the over-complication.

2. Don't use passwords.

It's 2018. Passwords are really not a good way to secure your system. You're going to end up building an email-based password reset system anyway right? So just cut to the chase and use magic-link based login only. It's pretty easy to do securely.

3. Keep it simple.

If you're implementing something you don't fully understand, or think you probably understand, but haven't considered every possibility, you're likely to introduce vulnerabilities. A simple auth protocol which you fully understand will perform better than a complex one you don't understand.
When Steve Jobs was away due to his illness, Bertrand Serlet presented Mac OS 10.6 (Snow Leopard) at the WWDC June 2009 with the startling slide that said "0 new features". There was sustained applause from the crowd. But in fact there was a very significant under-the-hood new feature called "Grand Central Dispatch". It is a low-level API that removes a lot of the pain of multithreading. Essential for OS X and iOS developers, as it turns out.
The biggest thing I'm missing is a quick way to switch between groups. Unless there's some kind of shortcut or other thing I'm missing.
That's by the way the reason there are so many tunnels in Stockholm but very few in Göteborg. It is very easy (relatively speaking) to dig tunnels through granite but very hard through muddy sediment. Some tunnels are still being dug in Göteborg but they are much more expensive than in Stockholm.

Nowadays, one of the main problems of digging in Stockholm is that there are already so much stuff dug out that it is hard to find room for new tunnels!
> Homelessness in the SF Bay area was the most confusing to me. I met people there who could've been myself in 10 years, but they were homeless or had once been homeless just because they couldn't afford a place to live there.

Mental illness and drugs (which really should probably be folded into mental illness) is actually a bigger factor.

1) Saint Reagan (/s) dismantled a bunch of the infrastructure to help those with mental illness in the name of, say it with me now, "Efficiency of the private sector". Consequently, the mentally ill wind up on the streets or in jail--neither of which is actually a good solution. We've only had about 5 years since removing most of the nitwits from the state legislature/Congress (the jungle primaries and redistricting commission have been in effect since 2010 and it flushed most of the Republican nitwits--and Mueller may get the remaining ones), and building/fixing takes more time than dismantling.

2) It also didn't help that some places were actually busing in their mentally ill population to San Francisco.

3) San Francisco weather doesn't kill people. Morbidly, being sufficiently mentally ill in, say, Pittsburgh or Cleveland, probably kills you in winter (and possibly summer).
I can never justify the use of delegates for pattern matching purposes. It's just way too much overhead, and so would discourage the use of these abstractions.
On GPUs, fp16 is quite a bit more power-efficient (and bandwidth-efficient) than fp32.

There are a lot of states of vacuum. Our space is either in rock bottom stable state or in metastable one.

Sometimes impostor syndrome doesn't need to be fixed. I am beginning to think there's one UC system school which is afflicted by Teaching assistants who shouldn't themselves be able to pass a programming job interview.

I've pointed out to interviewees that user input in one problem can result in circular references. I point out, as a hint, that thing A can refer to thing B, then thing B can refer to thing A, and you'd wind up with an infinite looping execution in one part of the code. How can we detect this? So then these 3.8+ GPA Comp Sci grads tell me to write a conditional that detects a 2-element loop. Not an algorithm that can detect the cycle, but just a conditional that only detects the 2-element cycle. Then I have to ask, well what about a 3-element cycle? To the credit of most of the applicants, they then try to incoherently describe an algorithm involving some kind of hash table, but then never give anything which is implementable. Once, the applicant didn't yet realize there can be n-element cycles, then proceeded to literally handwave away all graph algorithms.

These same applicants usually have a hard time writing their own recursive algorithm. Would you want to trust your startup coding to people who don't habitually think at least one step ahead? Come on! These things used to be covered in the first algorithms class! This should be Freshman Year stuff!
They mention that the solution remained cost neutral. Given that they're now running a huge number of additional instances, I'm curious as to how that could be the case. I wonder if they e.g. put a dollar figure on downtime, based on expected lost subscriptions?
Apple News is great. I use it more than pretty much any other app aside from Safari.

This has nothing to do with "getting your feelings hurt".

Not everyone is built as strong as you, it bothers some people.
Most of the replies are criticising the ghastly inefficient app. What is wrong with that?
How is the electricity used by the ev produced?

Electricity is not clean or dirty per se, as it is only a method of energy transport (well, it is a bit dirty per se, since it has losses - which can obviously be discarded if it is used to connect clean production facilities and replace dirty energy production)

Couldn't agree more with these points. I'd like to point out that

> It isn't a bad idea to read and learn from the OAuth 2 spec in order to make your own auth services

has actually lead to quite horrible auth systems. I've seen bad stuff in large enterprises due to this ("we're smarter, we'll solve it for our use case" -> "Oops, we didn't think about session replay").

I recommend OAuth2 for complex systems with many involved parties and clients. There it can really reduce complexity. For normal apps with maybe 1-2 consumers, cookie-based security is secure and good enough!
I have to say that I love the galaxy note 8.0 for note taking. So much so that I'm trying to buy up as many as I can find so that I will always have one.
There are 2 main reasons for this:

1st: I love the size. The 10s are a little too big to cart around in a jacket pocket, and the note phones are too small to be a decent notebook. (I must admit though, I'm rethinking this point, as I used to be a huge moleskin fan)

2nd: The Samsung s-note app from that time is awesome! Honestly, every time samsung comes out with a new pen based tablet or phone, I always check it out. And I'm looking for 2 features: a: the ability to import a pdf file & b: goddamned smart shapes! I suck at drawing, and so I love that on my 8.0 I can draw a shitty square or circle and the software will make it look all ship shape. But they seemed to have removed that feature from newer versions of s-note, and I haven't found a 3rd party app that can do just those 2 things.

Any pointers to an app that will allow me to import pdfs and draw on them using smart shapes would be awesome!
I think a big draw for homelessness in SF specifically is the abnormally mild and consistent climate. It rarely gets colder than 45F, or warmer than 90F.
The Intel CPUs were performance-competitive with the SD8xx chips at the time but most of the newer zenfones use slower SD6xx chips.

My experience with the Zenfone 2 was not very positive though. It seems to have been more Asus's fault than Intel's, but also Intel could have done a better job with their kernel. Yes the CPU was fast relative to its price (because Intel was dumping them) but almost everything else about it was not very good. Battery life was poor, seemingly because Intel never got core parking to work in their Android kernel (I also owned a Lenovo Atom tablet which had the exact same problem so I'm going to blame Intel here). Most apps ran pretty fast but anything with ARM binaries ran very slowly in emulation or in a few cases didn't work at all. ASUS's Android skin was terrible and had an obscene amount of preinstalled bloatware. There were loads of bugs, and installing updates was always a guessing game of whether it improved things or made it even worse. Sometimes GPS wouldn't work. The Marshmallow update was both extremely late and extremely buggy. The plastic back started developing cracks after about a year without ever dropping it.

The ability to run windows software in either Wine or a VM was a rather cool-but-useless novelty.
The Pope's Politics
You interview to get into Google at a specific level (new grad, SWE III, etc). They don't reveal which project you will be working on until the offer stage though. So it's possible that you can be in the interview process for months only to find out you'll be working on some kind of old legacy maintenance role.
I'm currently writing a PWA and using https://www.npmjs.com/package/sw-precache-webpack-plugin to generate the service worker on each build.
It's nice because it's a whole chunk of what would otherwise be application logic that I now give zero thought too.
You raise a good point. EnvKey minimizes the number of secrets that you need to deal with, but you still do have to protect ENVKEYs (the access keys that EnvKey generates).

The idea here is to create a simple 'base layer' for access that can work with any host. Environment variables fit the bill nicely because you'll almost always have some way to set one, and access to these will generally be coupled to server-level access.

That said, I'm definitely interested in adding other options for integration.

For example, I'm currently working on a way to store encrypted configuration in S3 buckets you control instead of in EnvKey's cloud. With this approach, you could define bucket policies (for both development and production-level secrets), that would restrict access by IP or by security group. That way, even if an ENVKEY leaked, it couldn't be used outside of a privileged context.

There are definitely other possibilities too. I'll look into the CNC server approach. Thanks!

“Your Office in Your Pocket” – Influential Entrepreneur Series
It looks really interesting, and I would definitely consider it (we're in the process of re-thinking our secret management solution. It works, and it's secure, but a bit clunky). We're a small bootstrapped company with only 4 developers currently.

I have to say, though, that the pricing looks a bit intimidating. Not from the cost perspective, but just the complexity of it all. And you seem to penalize growth (there was a discussion[0] on HN that I think you triggered actually).

I really find it hard to estimate how many config requests or connected servers we might have... And the last thing I want is for things to stop working or trigger some unknown billing when we're bootstrapping new servers, or re-jigging our configs.

Per developer sounds totally reasonable to me. You're aiming to make secrets management simple. Can't your pricing mirror this?

Visas Issued to Foreign Students Fall
Obviously, having a captive userbase to extract revenue from is good for their valuation. It probably isn't so great for the users though.
We already had reserved the failover capacity to ensure it was available during failover so running more instances is just taking advantage of that.
I used to be in the home-building industry...

With a team of three carpenters a hand-saw and hammers I could build a house like the one in the picture in 48 hours out of a sustainable material - softwood. With a nailgun I could go quicker still.

I could use a 4x2 studding wall, plywood, breather membrane, counter-batten, clad with larch featheredge. Once up a vapour barrier could stapled inside and recycled paper insulation blown in. Inside that I could line out with fire resistant plasterboard (drywall to my transatlantic cousins) (backed with urethane if extra insulation is needed). This design is easily prefabricated if desired.

To contrast with the concrete one this would

a) use sustainable materials

b) meet the building code of a developed nation.

If you are dead set on a concrete wall then just build a set of plywood forms (shuttering as it was called in my day) and cast it in place. A day to put the forms up and pour. The forms are reusable too once set. Now you have a bunker to insulate, waterproof and line out. In the UK you would need to build some kind of studding inside your pill-box for insulation and damp control, much like the 'barn-conversions' the UK is full of. This makes the concrete bit semi-redundant.

Sorry but I think this is a poor application of 3d printing. All we need now is a start-up to build a house with a cloud-based block-chain to get the VC's really excited.

If you want to look at some really quick constructions there are the brilliant post war 'pre-fabs' of the UK, designed to replace housing lost to bombing. Some could be assembled on-site in 4 hours! There are many still in use today. If it wasn't for the amount of asbestos used there may have been many more still remaining. https://en.wikipedia.org/wiki/Prefabs_in_the_United_Kingdom
I'd argue that a cross-internet reputation service would fix this problem.

1. The reputation system is affected by voting on all sites in which you participate.

2. The history of your participation across sites is viewable in your history (ala reddit, HN)

3. Your reputation is displayed with you participation wherever you participate.

Sites could then put reputation limits only allowing users above a certain reputation to participate. Making the cost of toxicity increase.

The biggest problem would be getting the walled gardens to adopt the system.
We don't know if either hypothesis is testable. Multiverse is not as mysterious as "god did it" (a.k.a magic), it's a very specific hypothesis.

You can "explain" absolutely anything with god/magic, and many religious people do. Try that with multiverse. It doesn't work.

Semantic Image Segmentation with DeepLab in Tensorflow
Just putting this into context, NYT has an article "How China Is Challenging American Dominance in Asia" on their front page. Not saying it's intentional on their part, but it may be useful to understand how the title "China is Winning" impacts the publication's larger narrative and how that can shape peoples' perspectives.
A major issue with using "useful/helpful-ness" as our metric for success is quantifying the term. A self-report Likert scale is susceptible to users just rating 1 or 7, or saying its useful
even when it was not (https://en.wikipedia.org/wiki/Self-report_study#Disadvantage..., not the greatest citation, but I am short for time).

The issue then looks at what is "success" in a MOOC. If the goal is to just have videos online, I'll just watch YouTube (as I have my own lecture series there). However, observing is considered one of the lower level of learning and things like Bloom's taxonomy point out there needs to be some type of interaction for better learning gains. These interactions require the student to have a more active role in the learning process. If they are not interacting with the system (logging in, watching videos, completing exercises, etc.), then they are not taking this needed active role. This is where "drop out" begins to be quantified and where then we can measure what worked, what didn't.

To address you example, if the user stops at 70%, researchers will ask "why?" From there, analysis of student behaviors, effectiveness of interface/instruction/material, etc. will arise. If the ability to study these things is confounded by the fact that the vast majority quit before completion, it makes it harder to answer the "Why" and "How do we fix it" questions.

Again, what we quantify as "successful" is still up for debate; but if a student drops out, it becomes harder to tell if they learned from the course and if it was student or material that drove that decision.
