I have spent countless hours trying to use the LIFX API to create a reasonable candle flicker. Probably 40 hours of tinkering, getting inside its head, figure out that it really can't.

I wish I knew about this.

Seriously, I need a smartphone controlled candle.

Yup thats why I use the web client. I have to use it for work, otherwise I would've just used some XMPP client hooked to the public Jabber network.
I assume it will be backed by the same transport channel used for Handoff / Continuity, which is E2E-encrypted between devices and work on either wifi or bluetooth.
When you have kids and perhaps an hour per day alone with your spouse, saving a few minutes on setting the mood has real utility. Imagine the person saving a few minutes finding matches just spent the previous hour doing dishes, cleaning up Lego, taking out the trash, sorting mail, and spent the hour before that wrangling kids into bed while they try with all their might to avoid brushing their teeth for the nth day in a row.

Don't begrudge them their remote control candle.
It tends to happen when the following are true:

a) Previous government experience is highly valuable in private sector employees

b) Government pay is less than this value

b) affects regulatory capture in two ways: it allows civil servants the opportunity to get massive raises by going private (and incentivises them to be nice to future employers) and cripples the recruitment of highly talented individuals who are less dependent on industry advice. I don't think attacking a) is feasible in a modern regulatory state, but b) is readily doable if a government is willing to significantly deviate from standard salary scales for high-value industries. For example, SEC salaries would have to be much, much higher than Department of the Interior salaries. AFAIK, Singapore already does this and has very high talent retention rates. Even within the US government, it isn't entirely unprecedented, since an E-3 Navy special forces operator probably makes 8x the salary of an E-3 Army public relations specialist.
"Just because it's the default doesn't make it easiest nor does it make sense as the default necessarily"

I used to throw them together in Frontpage or Dreamweaver with a few optional scripts. Scripts for things like page counters or menus I just cut and pasted off dynamicdrive.com followed by tests in several browsers. Backend handled forms and such. Worked on every browser, loaded up fast on dialup, and everyone knew what my HTML/CSS code did without training. Can't say that about most of these sites and frameworks these days. So, I'd say it's easiest and a sensible default.

To be clear, I'm not critiquing complex, web applications that truly need advanced tooling client-side. I'm talking about 90+% of what's out there that just publishes content with minimal dynamic elements needed.

See https://news.ycombinator.com/item?id=12541290 for one rule of thumb and methodology.

My experience is that most tests will come out under 5% differences. But most organizations will have some test that they could run with a greater than 15% win.

If your business scale does not allow you to run tests and detect the wins you hope for, you're better off following other people's best practices than you are trying to discover best practices from running your own tests.

Also note that most businesses have a "conversion funnel" where there are a number of steps from visitor to getting paid. If your business is big enough, you want to focus on getting paid. If your business is too small to get results that way, you should get started with just the first step in the funnel. That's what Patrick did with the trial signup form.
I didn't know about this! My last experience messing around with compiling for the PRUs was really frustrating - I gave up after about three days' screwing around with freeware tools that didn't work.

I'm curious why the clients chain requests but the servers don't chain replies. It would be straightforward for servers to emit a CT-style log as they go, thus forcing servers to prove that all their timestamps are in order. With a bit of refinement, it would also allow servers to prove that they didn't generate, say, Thursday's timestamp prior to learning a nonce that was sent to them on Wednesday. If nothing else, this would substantially strengthen its use as a timestamping service.

Also:

> It is the case that the signature, even assuming one request per batch, will add some number of microseconds of latency to the reply. Roughtime is not going to displace PTP for people who care about microseconds.

I'm not convinced that this should prevent extremely precise timestamping a la PTP. The server just needs to indicate, outside the signature, how long its processing took. Sure, this prevents authentication of the fine-grained time, but a client could easily bound the amount that a server can cheat.

I've never heard of a single infrared camera being used for depth-finding...

Are you thinking of some active scanning technology such as LIDAR? Or the infrared grid-of-dots projection that the kinect uses?
Yes, in many areas:

* Higher order functions now specialize on (and possibly even inline!) passed functions

* Anonymous functions are now fast, too

* Fused broadcasting can avoid intermediate allocations and only make one pass through the array

* User-extensible bounds checks allow custom array types to opt-in to skipping bounds checking, enabling SIMD-ification of some for loops

That said, compilation times may take a bit longer due to the LLVM upgrade… but this resulted in an even stronger push towards better performance in many other areas.

i dont think its fair to accuse and scold scrollytelling.
On their homepage they have a tech section where they state:
"Our software is built on top of the Open Source version of Pageflow. We are committed to giving back to the community, which is why we are active contributors, and have open sourced our software too."
and they have put a lot of their software up on github.

Yes, this is very similar to Wordpress companies. However it is still their source code, and scrollytelling's webpages are better... dare i say.
I think it's a lot harder to get past TypeScript's type checker. It's probably possible, but I can't think of a way to do it off the top of my head without casting to any. It's a lot easier to show correctly executing javascript programs that would be rejected by the type checker.
How?

Do you think the infringing code would have been removed without public shaming? Not necessarily out of malice, but in large organisations these matters tend to be forgotten or idle for a long time.

Anyway they did try to settle things amicably, to no avail.
Is there anything noteworthy under the hood that would compel power users to upgrade? None of the features listed on Apple.com look like things that would be useful from my perspective.
"While it’s probably neat to be able to light a candle from your phone, it’s a fantastic example of something the world could do perfectly well without."

The world was doing perfectly well without a lot of things we have today. Sometimes the ideas seen as stupid are what open doors to previously unimagined possibilities and innovation.
This happens at several levels. Smartphone-controlled candles are a great example. Personally, what I find sad is that while many of the best programmers in the world are busy writing the next blogging framework or javascript UI library, scientific software that can make a great impact in our lives (and is a huge challenge even for the most experienced developer) is being written by PhD students with zero experience in programming.

But I do not think the experienced developers or the inexperienced students are to blame here. To be honest, I do not know who would be.
> Imagine the person saving a few minutes finding matches

Seriously? This person owns candles. Chances are they keep a lighter or match next to them. I'm all for user empathy, but this just seems to be making up a use case that seems really unlikely.

Those are nuclear-sized dollar numbers. I don't know of any solar PV farm that has been built in a single $3 billion phase. Flexible scaling is one of the big advantages of PV projects over other types of electricity generation projects. There are economies of scale as solar projects go up to (IIRC) 20 megawatts, but above 20 MW costs per unit are pretty flat. So investors can take a much smaller risk with e.g. a $50 million project of 25 megawatts, see how it performs over a few years, and invest in larger projects (or a larger number of tens-of-megawatts projects) if they like the results.

5 years is also an unusually long timeline for constructing a solar PV project. The largest PV project in the US, the 579 megawatt Solar Star in California, was completed in 3.5 years. It also began supplying (partial) power to the grid about a year after construction started. Since a big PV project is practically a bunch of little projects tiled together on the same site, energy payback and financial payback on a big PV project can begin well before construction officially completes. That's in contrast to big "chunky" generating investments like a traditional storage-backed hydroelectric dam, or a nuclear reactor, where you have to build in large increments and can't turn on parts of the plant as you finish them. If small nuclear reactors ever get commercialized -- and I hope they do -- they too should offer more tolerable financial/schedule risk than today's gigawatt-plus reactor designs.

Until they get US citizenship they do remain Indian nationals. And for Indian origin people it can easily take 10-15 years after graduation to get US citizenship.

Also identifying with India and actually going back and living in India are two vastly different things. Most of them will talk and plan but never leave for India as facilities, money and comfort of the first world will be just too much leave. Of course some of them may go for CEO/very senior position to establish office in India and then come back after some time.

Please stop implying that having a critical opinion implies a defense of banning these things.
Ehhhh... I disagree on a few levels.

I do automation projects for friends on the side and every project starts with what is essentially flipping a bit or driving an output and grows from that. Home automation really is a matter of solving a dozen small problems to resolve the bigger one. To say automating a candle has no tangible benefits is looking at the small problem and failing to see how the larger problem exists outside it.

What does it take to light a pilot light on a burner, heater, dryer, etc? I'm going to guess that the smaller problem involved in the bigger picture here is much the same. I definitely could sell a cellphone controlled burner in my job (though the regulations that sit in place are probably another hurdle.... outside the scope of this discussion though).

And here's the other stupid thing. If people are willing to pay for it then it's not a bad idea. Someone was just clever enough to see if there was a market of people willing to buy the "smaller problem" without thinking of complicated ways to apply it. At a simple level, if its profitable, its useful.

That profit likely drives this business to solve bigger problems. Think of it as a seed funding by creating stupid candles to apply technology to the larger problem. They don't necessarily have 6 or 7 figures of cash sitting out there to solve the big problem but to rope a bunch of people into the candle is enough to get them off the ground running.

On another side of it ask what the person would be doing if they couldn't do that. There's no guarantee they'd gravitate towards something deemed "Beneficial" to humanity.
>federal law doesn’t prohibit the discussion of classified information over unsecured networks."

Seriously? "Oh, man, we sure left a loophole you can drive a truck through! Better update the training materials to make sure clearance holders know this is kosher..."

Sorry, but my prior on this claim is just way too low to casually accept that the analysis, as given in the first link, is plugging the relevant laws into the facts. Classified-material law just doesn't make sense if something like that is legal.
Dedal: accelerating construction industry’s transition
I also find this frustrating. For applications where it happens frequently, you can map paste/paste-and-match to keystrokes you can remember using System Prefs > Keyboard > Shortcuts > App Shortcuts. There isn't a global change you can make without 3rd party tools, AFAIK.

For frequently-used shortcuts that have hard-to-remember modifiers, I change them to the full set of shift-ctrl-opt-cmd so that just mashing my hand across the entire corner of the keyboard will get the job done. Has the nice side effect of (usually) avoiding the unexpected overwrite of other default app shortcuts.
People care because its a pretty big early milestone for a company. Especially if it happens pretty quickly and you can talk about some customers.
Instead of asking for a prospective employee's salary history, I think that an ethical employer should disclose the anticipated salary range for a position, and confirm that it would be acceptable if an offer were to result from the interview process. Any other approach is about creating a negotiating advantage for the employer.

It’s easy to knock something together with JS. It’s very difficult to make it work well, certainly in our experience harder than having reasonable fallbacks.

I've had to use CCS a few years ago, and it was a buggy monstrosity. I don't understand why silicon vendors have to wrap their dev tools into such horrid IDEs. One reason I loved working with AVRs is that I could get a gcc-like interface, so that I knew exactly which options and parameters were used rather than some godforsaken IDE do some magic for me and get in my way. Having to hunt down options in modal windows and tabs is enough to make my blood boil just thinking about it.

Embedded development requires very precise control and knowledge about what you're doing, and IDEs more often than not get in the way of doing that.

> Siri and Google both do fine with my general questions and commands

I think it depends. For instance asking Siri while my phone is locked what time it is and Siri will tell me (useful when I'm across the room, in the shower, etc). Google? I ask it for the time and it tells me to unlock the phone. Yet Siri can't handle asking anything about current events whereas Google can.

If only there were a way to combine them or at least see progress on them working on their shortcomings.
Your resume is so far down the list of things that will get you the job that the formatting question should go to a specific person who can answer the question.

That is, if you can't get the basic question of "best resume format to get through hoops at company x" answered, any formating work you could do is swamped by orders of magnitude by building contacts in the company work.

What is it with people these days and making all kinds of contrived, fantastical excuses to rationalize an idealized outcome. There is absolutely no way you can even have a chance at accurately guessing second order derivative reasons. Reality is that they were cut and the would not have been cut if they had been valuable. There is no sense in playing ifs, ands, or buts in a contrived manner.

The conventional definition of "pure" is that the result of the function is the same for the same input. You might include "throws an exception" as a possible "result" for a JavaScript function, or you might not (generally not).

So the fact that your implementation of mean() returns a float when you expected an int (honestly, there are no ints in JavaScript, just floats which happen to have integer values, why would you expect that?) or returns undefined doesn't mean that the function is impure, it just means that the function doesn't do what you thought that it should do.

For example, I can write the function:

function addOne(x) { return x + 1; }

I think there is no conceivable generally useful definition of "pure" under which this function is not pure, and yet... it could overflow the stack, it could run out of heap memory if you pass a string depending on how much heap memory is available...

The generally useful definition of "pure" is just that if f is pure, I can save y = f(x) and use y instead of f(x), or vice versa, or I can eliminate f(x) completely if I don't need the result. The fact that extreme corner cases, like out-of-memory situations, can result in slightly different behavior is something that we like to gloss over.

Back in the day, no link on a google domain that pointed to a google domain was a 404 link. That's right, zero 404s, site wide.

So the 404 page was pretty much only seen by IT folk--people who would type in their own URLs instead of clicking links...

And those people, the people who type a lot... had probably seen the old meme in which the trailing ! in a string of !!! is replaced by a 1, as would happen if you were typing quickly and let go of shift a little early...

Thanks - all very important questions. A large part of marketing is perception. There was nothing radically different about the Mac when it got to the Intel/BSD revision - other than the overall user experience. Everything felt very clean and precise - from the hardware to the software.

That said, I think there is huge room for improvement in a couple areas. One is rethinking the programming environment - how easy it is to get into, how fragmented it is by a hardware ecosystem, how can you gain C-level performance while making the environment less rigid, how can you make dependencies a no-brainer, how can you make a UI system so good that nobody will want to use anything else - the list goes on and on. I would love to rethink hardware but realistically that is the difference between a million dollar startup and a billion dollar one. That said, the superficial aspects of hardware have room for improvement or niches that can be attacked. For example, I would love to have a portable device (like a laptop) that is able to compete with the comfort of my desktop (and yes, I regularly use the best laptops - they do not compare to my desktop in my experience :) ). I.e. something that can be ported around easily, but does not necessarily have to rest on my lap.

Does the world need another OS? Technically not - because need is a very strong word. :) Does the world want a better OS? To be honest, I am not sure how strong the demand is or how great the apathy is there - I think only the real-world market could tell.

In a way, its really similar to the question "do we need any more programming languages?" We can make do with what we have, but I would be arrogant to say we could not produce anything better. :)
