It’s great advice because it’s a tangible change individuals can make immediately. There is very little we can individually do about the 100 companies, or do at all in the short term. This problem will need to be tackled on multiple fronts simultaneously. Advising people not to do something that could make a real difference doesn’t seem particularly helpful.

I’m fed up reading comments along the lines of ‘we shouldn’t try to solve this problem, because we should be solving this other problem instead’. In every case I’ve seen this argument, there’s absolutely no constraint at all preventing us from doing both.
That's interesting. Can you elaborate? How does it help you?

I build software systems which integrate a software front-end app with hardware, and I don't think I agree with the supposition that using an app to set up hardware is a negative.

Its just that I think that an app/hardware integration ethic definitely has a place in the world. For example, hardware which works with Apple, without allowing third-party (not even Apple) involvement, is a battle being fought.

Hardware vendors should be encouraged to ensure their hardware remains useful for generations, in my opinion. Apps always go stale while the hardware remains operational.

Of course: none of this forgives the vendors using it to spy on its customers.

Hardware like this, anyway imho at this market, is a platform battleground. In all honesty, we have more computer vendors battling it out now, than ever before.

More than likely, putting "compatible with iOS" on the box of an expensive speaker means more shelf-shopping customers. Alas, Bose and Apple probably have, at least, MFI-level involvement...
Maybe it wouldn't be so scary for you, but is everybody else's computer is compromised, did you really win much?
Of course it always depends on the perspective: For a fisher man who wants to export seafood to the EU this is good news. For the average family which has to pay 20% more for everyday goods like vegetables from the Netherlands, not so much. However, Britain has a large trade deficit in goods and services, so in total it is bad news.
All companies exist to serve customer demand, or to serve companies that serve customer demand. Sure, they should be regulated (... thus increasing the price of consumer goods?) On an individual level, traveling less, buying less stuff, or buying less damaging stuff is the best that most people can do.

They only rely on ads because that's the path of least resistance. If the GDPR eventually means that there is no Google or no Youtube anymore – which is not very likely – that just means the cost of Google/Youtube doesn't justify its benefits, assuming markets work at all.

Tea was engineered by the Chinese for thousands of years. Initially it was drunk for its stimulating qualities, as some sort of medicine. If you pluck tea leaves and try to make tea yourself the result will be absolutely unpalatable. Through hundreds of years of growing it, the Chinese figured out rather non-intuitive tricks to make it taste better and better.
The British tried to grow their own tea unsuccessfully for decades. In the end Robert Fortune illegally brought a group of trained Chinese tea workers as well as stolen seedlings to the East India plantations in India.
> I've often wondered what a theory of computation based in differential equations would look like.

The theory of computation is not based on anything; it is fundamental in the sense that it exposes laws of nature (it is heavily based on physical limitations) independent of the means of talking about them. In a very strong sense it is more fundamental than mathematics itself as it is concerned with how hard it is to obtain the answer to a mathematical question without regard to the process of obtaining it. Different representations may, of course, assist us in proving certain theorems in the theory of computation or other areas of computer science.

"Community Care" is a bit of jargon that has a well established meaning.

I think you're suggesting that we lock up everyone who has a mental illness, and then release the ones who aren't dangerous.

About 1% of the population has schizophrenia. About 1% of the population has bipolar. Let's say about 1% of the population has a severe personality disorder. If there are about 320m people in the US you're calling for the incarceration of 9,600,000 innocent people.

The vast majority of those people are not a danger to others, or themselves.

What we need to do is invest in community care, have short hospital stays available if needed, and have forensic "secure units" available for the small numbers of people who pose a serious risk of harm to other people or who have committed criminal acts while mentally ill. We do this because it is cheaper; it is more effective; it is safer; and it respects people's human rights.

I don't think this follows. They could be clustered. A cluster could be made to look a lot like a conventional big-iron server.

We're talking about replacing a single large machine running, say, 16 VMs (each with an IP), with 16 small machines (each with an IP). Put an Ethernet switch at the last-mile and it's virtually the same, no? Different number of MAC addresses, sure.

That arbitrary computation could be described with differential equations is an immediate corollary of Turing's 1936 paper: because a Turing machine could be constructed in the physical world, its operation can be described with differential equations. An immediate corollary of that is that differential equations are undecidable (i.e. differentiability does not give us more power).

Not what I was expecting, normally I would expect a real time clock to keep running when the system was turned off, so you would be able to have accurate current date/time.

> There are more than 2,000 billionaires worldwide but only about 480 NBA players (32 teams with roughly 15 people on the roster). And if you think about it, becoming a billionaire usually involves multiple skills (good at programming + business, bill gates. Good at research/analysis + cultivating a rare temperament that allows you to act on the insights produced by the research even when everyone around you is losing their shirt, Warren Buffett etc, etc).

That's not really true. Once you are billionaire you can stay a billionaire for decades. Meanwhile most NBA players don't have long careers, many stay in the league only for a few years. I'd expect that over 10-20 years there have been more NBA players than billionaires.
You could take a CPU design at the transistor level and use the techniques from SPICE to turn it into a system of ODEs. But that seems like a massive complication that would make it hard to reason about high-level concepts.

This is a guess: if an app can do a Bluetooth scan it can then look up the device IDs online and figure out where you are. So it needs location permission. Perhaps Android should give apps anonymized Bluetooth IDs.
Could you just put the time estimate in the title of the task?

For such a simple project, there is going to be strong urge (from both internal and external sources) to go down the path of feature creep.

First an hour estimate, then uploading photos, then descriptions... pretty soon you've got a half-baked Trello and user attrition because you're not as good as Trello... or Airtable.

I don't know much about the Apple II but I'm surprised that external circuitry is required to effectively count the number of frames. Isn't there already a way to count the number of frames without hardware hack on this computer?

Beyond that, an RTC without battery backup to maintain the time across reboots might not be extremely useful. Given the low precision I'd consider this more like a hardware timer than an RTC, but I'm probably splitting hairs now.

It's still a cool hack nonetheless, it's always refreshing to see how simple and straightforward it is to hack these old machines, both in hardware and software. Can you imagine doing something like that on a modern system? I mean, it's doable but it'll take more than three lines of assembly to get it to work correctly.
that was chosen to build smaller ovens, not because of a "resonating frequency".

Yes, I think that at least some of what Von Neumann is calling for is complexity theory.

It's easy to forget how recent complexity theory is. While Hartmanis and Stearns laid the foundations in 1965, its first concrete result came only in '71 (Cook) and '72 (Karp), and it took much longer for more results, and, more importantly, their meaning, to sink in (at least until the '80s if not later) among computer scientists who are not themselves computational complexity researchers. In fact, some of the most basic results complexity researchers rely on are from the mid 80s (circuit complexity), which makes complexity theory one of the youngest fields in computer science. It is about half the age of neural networks, and even younger compared to programming language theory.

Some famous assertions/hypotheses/aspirational programs in computer science, including by people like Dijkstra, Tony Hoare and Robin Milner, predate complexity theory, and should be seen in a different light because of that. And because it is so young compared to other branches of computer science, it is sometimes ignored by researchers working in older disciplines, if only because their own basic results predate complexity theory.
The "normal" physical systems we build (say houses and hydraulic systems) are mostly "continuous". This means small changes in the inputs generally result in small changes in the behaviour of the system. So, for example, if the screws on your kitchen cabinet doors are not tightened quite enough, the cabinet doors might wobble a little -- that is, a small change resulted in a small change.

On the other hand, systems based on digital logic are very "discontinuous". A small changes in an input can result in the system behaving vastly different. A single-bit error in a computer program can result in an if-then-else switching from the true branch to the false branch, and thereby running an entirely different piece of code. So your computer is a single bit flip away from fintech entrepreneurs using your entire bank account to rent AWS time to mine Bitcoin.

In general, we are drawn to discrete logic because it's easy to write programs to do different things based on different inputs. However, von Neumann was worried about this, because no machine works perfectly -- every computer runs with a certain probability of error, and computers run fast enough that even a low probability of error can compounds very quickly. And if a single small error can result in radically different results, how can you trust the result of a computer program?

In this note, written in 1947, he expressed the hope that if you could make computers behave continuously, you could not worry about small errors, because they would only have a small impact on the result.

However, a few years later von Neumann ALSO invented the alternative, modern way of handling these issues! In his 1956 paper _The Synthesis of Reliable Organisms from Unreliable Parts_, he proved that it was possible to use redundancy in a way to drive the error probability arbitrarily low, enough that you COULD trust the output of a computation.
Enthalpy is energy required to create a system. Internal energy required to make up the system (to bring it's internals to given Temperature, pressure ect), but there is additional work needed to position the system in the universe (that is, to free some space for it, like moving (working on) water or air to place the system of volume V in it).
Meatless Mondays won't cut it. But even if we were to offset our worst carbon excesses—such as intercontinental air-travel and meat—ethical consumerism won't solve the climate crisis. Most other people simply won't offset their emissions. We need coordinated policy approaches to climate change.

And policy needs to be global in scope. Because even if advanced economies were to reduce their emissions to zero, this would be insufficient to prevent warming with substantial risks. Note that emerging economies are producing an increasingly large share of total global emissions, while the share from advanced economies is dwindling, now accounting for only 35% of global emissions. This trend continued past 2015 and is forecast to continue in the coming years.

By 2040, emerging economies will produce 75% of all emissions, while only 25% will come from advanced economies.

But policy-makers are still stuck in a mid-2000s mindset. Back then, their emissions were still the highest in the world and they had to focus their policies on reducing their own emissions. This no longer makes sense.

Advanced economies have a special obligation to do more to lower emissions in all countries. Why is it our responsibility? Because our per capita emissions are still the highest and we have emitted the most carbon since the industrial revolution.

Only if the policies of advanced economies lead to reduced emissions in all countries, can we prevent dangerous climate change. The most effective policies to prevent climate change are those that stimulate clean energy innovation. In other words, those that stimulate progress or breakthroughs in clean energy technologies (or any low-carbon technology that lowers emissions as well as demonstration projects, i.e. RD&D). Providing the global public good of cheaper clean energy technology helps all countries reduce their emissions.

Yes. The CPU ran at 1 MHz and instruction timings were deterministic and well-documented, so it wasn't hard to write a delay loop for any number of microseconds.

There were sound synthesizers that could play chords, all based on toggling a digital output connected to a speaker with the right timing patterns.

I think that Von Neumann raise three important issues, two of them are largely solved, and one of them is not yet solved.

- Hardware failures

- Complexity theory

- CS and Formal logic is combinatorial rather than analytical, we can't use the powerful tools of mathematical analysis to solve those combinatorial problems.

Bluetooth can also be used to track location with those beacon things shops us. I believe this is the reason they changed it (Bluetooth didn't used to need Location perm).
Just note that the perf loss is 20-40% in their benchmarks, so in your case, you'd need to bump that 4.4Ghz to 5.5-73.GHz, which is a tall order.

In any case, the article is worst-case FUD-like nonsense. No idea what the eventual perf loss will be, but it's a safe bet it'll be less than that.

Consider that it's likely safe enough for 99% of usages for the OS to allocate CPU cores to processes in pairs, and that would incur only a small penalty. And something smarter is almost certainly possible, too.

I'll stop themeing apps and their icons once I don't see a single piece of software that has an UI and an icon look like as it were made in the 90s, also implement dark theme. Providing a more consistent UI for new users on a distro is also better idea than leaving it up for the developers.

The GNOME back button being wrongly themed is solved by switching GNOME to dark mode (`gnome-tweak-tool`) and a dark theme. The engine isn't the best but devs don't make it easy either.
