I find it interesting that within the space of a human lifetime these words can go from secret language to common usage, completely divorced from where they came from. I wonder what my Grandparents think when I discuss having a bevvy.

“On average, compiled languages consumed 120J [joules] to execute the solutions, while for a virtual machine and interpreted languages this value was 576J and 2365J, respectively.”

IMHO it's not quite right to evaluate energy efficiency just by looking at the runtime performance. Compiled (incl. JIT) programs have to be compiled. So for compiled programs, you have upfront costs (e.g. rust, haskell much more than c), you would have to include in the calculation. Then you have programs/script that run once (a day maybe). I wouldn't be surprised if taking this into account would change the calculation.

Yes, I think smartphone keyboards are obviously much better than a dumbphone, but worse than a PC keyboard. The problem is that now smartphone keyboards are used so much more frequently, in so many more situations. You can often tell when someone is typing from a phone in a IM message, an email, or a Hacker News comment.
It's pretty obvious if you're running RabbitMQ which ranks highly in the output of `top` even if no messages are being processed.
Which direction should our society's attitude lean for false positives:

- a few dead innocent cops and some bad guys get away

- a few dead innocent civilians and less bad guys get away

To me it seems clear that the risk should lean towards officers, who chose to be in a dangerous profession, instead of random civilians who have no idea what is going on. Some bad guys getting away seems inconsequential compared to accidental death of innocents.
The difference is with a sock I need to consciously put it in and take it out. Getting a text message with the phone at an angle so I can read it doesn’t matter to me because I still need to pick it up and carefully line it back down to respond.

Yes it takes less than a second but you know what’s even more effortless? A wireless charging mat that I can just set my phone onto.

Not sure what’s so hard to understand about this.
I really like BSD myself, I used it as my primary OS for both desktop and server back in the early 00s.

Nowadays, with a container-centric cloud architecture, it seems like BSD doesn't really have a good answer to Kubernetes, Nomad, etc. If anything, the projects are experimental and/or hobby projects.
That is quite shameful. How to store data in the car is at least a complex problem. Theoretically I might want the data there and other car companies might be doing the same. I assume the GPS devices store previous navigation that is readily accessible in case of a crash. But not wiping data on a refurbished device has no excuse.
I think they should have a bit of fun among themselves even if just how one dress. I did note one of the girls dressed d. park in one of the news. So be her.

I guess it is because no other mat has overlapping coils. In the apple one they wanted you to not care where you put down your devices. Since they have so many coils, it then becomes likely that the 3 active ones overlap.
Just installed openBSD on my 2007 MBPro (OS X does not update etc.). What a charm.

I bought another MBPro in 2017 because I needed the power and the old one had become unreliable (shutdowns due to heat etc.) I use now the old one for home work and as a remote terminal. Could not be happier.
A USB thumb drive. But that would be too easy.

I second that. I have an Anker charging stand and it works beautifully. As it is a stand, there are no alignment problems, and it is easy to keep using the phone, especially, as face id always triggers when looking at the phone when I get a notification. The charging mat I have requires careful alignment and while lying flat, face id usually does not trigger.
Every modern used car on every lot in the country still has the previous owners phone book transferred via Bluetooth along with their navigation destinations and probably garage programmed too. This isn’t new or unique to Tesla.

Just plain global arrays are technically an indirection, but I suppose the performance impact is hard to measure in practice. You have a small number of global pointers (most project will have < 100) that can be expected to be in the L1 cache. The compiler can easily optimize the code by not loading the value of the pointer on each access to an element of the array.

Pointers to pointers are one level more of indirection, both the properties I just described are probably not achievable in practice.

> Why does putting all the information together imply a loss of modularity? You could have structs inside structs, defined in separate files,

Because there is a place that must know them all, bind them all together. And all the client code that wants to use any of the things in there now depends on EACH of them (for a liberal but very real definition of "depends").
> I think another contributing factor to the decline in quality of IM conversations is the use of phone keyboards. They are so much worse to type on than a real keyboard

If I am at a place by myself then I just talk, using speech to text. Speech recognition is pretty good these days, I usually only have to fix small things in the resulting text (names, etc.), and it's much faster than typing a longer message.
Comparing Go's GC to one of the many specialized fine-tunned Java GCs is pointless, I find.

I'm sure you're also aware that recent Go's GC pauses are sub millisecond for most use cases:

"We now have an objective of 500 microseconds stop the world pause per GC cycle." - 2018 Go team

https://blog.golang.org/ismmkeynote

My personal experience with microservices is to expect STW pauses in the 350 microsecond range. The best part is that it requires zero tunning or developer's attention while still being light on memory usage. Can't say the same for Java's default GC.

» The reality is, Battery life on phones have improved to the point that I also rarely need to charge my phone anymore other than what I'm about to go to sleep anyway.

On the Android side, batteries have gotten bigger with phones but more importantly the OS is getting better at battery management. With lineage 16 (Android pie), I can choose to enable battery saver at 75% battery.

Language runtime analysis for server-like programs seems obsessed with putting everything into a single process and address space. With C/Unix, traditionally or at least since inetd, the way to go is start a fresh process per request, which mostly just solves the problem of manual memory management (eg. because the O/S clears up the mess you left behind), at the price of latency. I'd like to see a benchmark comparing these approaches, since gc is far from being free of overhead either.
Your buying Apple. Price as an argument is long gone.

This whole thread is really asinine.

Wireless charging is a seamless, elegant solution to a problem.

It is not the only solution.

It is not a perfect solution.

It is not the cheapest solution.

It is not the most cost effective solution.

It is likely not the best solution for your battery life.

Docks and wires are not an elegant solution.

That's all the argument is.

One is old, painful and requires though, the other, does not.

It doesn't need to be a perfect argument, you don't have to buy into it. But unless you've tried it, please keep your opinions to yourself, because there is unlikely a chance you'll really "get it" and your single sided perspective is really not that useful.
> I know many who almost never charge their phones, essentially always living at 5%.

That's amazing since I'm the opposite. I always try to be near or at 100% (both phone & laptop) while I'm at my desk.

My local airfield is at -19ft and the landed altitude reported by Mode-S varies from -25ft ( GNSS sourced ) to -275ft ( pressure based on 1013hPa ). Hence why asking for the local air pressure QFE is essential.

I thought about some about 360 videos and oh boy it looks hard. First of all it uses obnoxious amount of data. Oculus go for example has resolution of 2560 x 1440 (1280x1440 per eye) and horizontal fov in region of 90 degrees. You need about 5k in horizontally to fill 360 degrees of horizon and at least 1440 vertically for video to look decent. All this bandwidth and even that is not that good. For best vr experience you would need to go for 360 3d video so final resolution is doubled. That gives us 5120 x 2880 video. Couple that with 60fps for additional immersivness and I don't even want to know how many gigabytes you will need for any mid length video. And that is only technical part of problem.

Second problem is that there is no framing in cinematic sense. You don't worry about filming crew accidentally getting in frame or bouncing off mirror. You need to either hide them entirely or embrace somewhere in 'frame'. It's okish in documentaries or videos from live events (eg music concert from front row). Immersion in headset gives you another problem. Any scene cut needs slow fade to black so you don't induce motion sickness (no fast action scenes with changing camera every other second). Speaking of motion sickness, camera must be fixed or move very slow.

Vr and 180 or 360 movies are very young and we need whole new generation of filmmakers but from what I have seen it has great potential. Properly made 180 3d films are immersive and you actually feel like you are there

Well in general it's always a nack when I get that kind of message. I don't want to be pressured into starting a synchronous conversation if I don't know what the conversation is going to be about.

"Hey got a minute?" => no

"Hey got a minute for A?" => yes

"Hey got a minute for B?" => no
It is. For a majority of the fleet RNP1 and RNAV5 use GPS as the primary means of navigation with INS as a backup for a limited amount of time if GPS is unavailable.
Ideally, the best way to balance online rhetoric is for left of center creators to generate more frequent and more compelling content (without admins needing to finesse algorithms or censor/shadow ban content in pursuit of a digital Fairness Doctrine).

By sheer quantity mainstream media leans center left and online indie media leans center right. You could say that taking the whole landscape into account that constitutes some kind of tenuous balance overall - but it would be nice if both mediums were more balanced.

Interesting aside: conservative talk radio has always been more popular than liberal talk radio - is this just the online expression of the same phenomenon? People on one side of the aisle tending to enjoy listening to and watching political content at greater length than their counterparts?

> I'd be kinda shocked if airplanes were just jam-syncing the clocks of their nav computers to the output of a GPS, and then had those nav systems be dependent on that time

Obligatory not an aircraft software engineer, but I can say with some certainty that this is not the case. Aviation software, despite the recent issues with the 737 MAX, is generally designed and implemented to very high level of redundancy and SPOF-avoidance.

From an airbus manual, to give you some idea:

A300-600s, A310s, A320s, A330s and A340s with GPS PRIMARY

The navigation system of these aircraft consists of 2 FMS, 3 IRS, 2 GPS and radio navaid sensors. The GPS position is primarily used for FM position updates, however if GPS PRIMARY is lost, FM reverts to radio updates or to IRS ONLY navigation when outside radio navaid coverage.

FM(S) = Flight Management (System). IRS = inertial reference system (THREE of them). If GPS is lost or malfunctioning, the FMS falls back to that - which is periodically updated by reference to RNAV ground-based radio beacons. GPS could simply switch off worldwide and aircraft would be fine, just like they were pre-GPS.

There is no conceivable reason the navigation system would especially care about the time being received from its GPS units, let alone perform some critical calculation based upon it. This article is pretty uninformed fear-mongering.

Unless the objects you're working with happen to be contiguously arranged in the arrays then it might be 100 cache lines for those 100 pointers.

> the government decides how much to spend on care

This is true, there are limits to what the government will pay. The NHS, which isn't far from the gold-standard for socialized medical care, does indeed not stock some drugs that are deemed too expensive. Here's a good write-up of QALY's and the NHS:

https://www.bbc.com/news/health-28983924

If your child had been born with spina bifida in the UK, all treatment would have been free. This treatment would include (from 2018) pre-natal surgery, post-natal surgery, physiotherapy for life, occupational therapy for life, special educational needs, mobility aids for life, and all manner of treatment for association problems, including kidney treatment for life[0]. Here's a summary of the NHS treatment for it:

https://www.nhs.uk/conditions/spina-bifida/treatment/

> In a country with socialized medicine they’d probably have just let her die

How much research did you actually do on this point? I'm always amazed by how much Americans suck up the death panels bullshit. If a fraction of what all y'all believe about socialized medicine was true, then free medical care wouldn't be free at point of use in literally every other civilized country on the planet.

That you are willing to believe all the world except Americans are idiots for the way we have our healthcare setup beggars belief, and reflects poorly.
and I doubt your claim, that extending a meta-circular toy interpreter with some remotely macro-like feature will help any Lisp beginner to understand Lisp macros.

There is already a bunch of good material out there, teaching the use of Lisp macros for both beginners and for medium-level users. Advanced-level users will find a lot of teaching&research in the Scheme literature/...

Paul Graham himself has written a good and well-known book on it. it does a good job explaining macros and their use. It's called 'On Lisp' and there is no need to replicate its content here.
