Last time I looked you need a huge amount of elements to get good angular resolution. For Wifi two things.

1. All you care about is getting the ratio of multipath energy high enough that you can resolve independent signals.

2. Remember RF power is measured in db and your radio's power consumption is in linear watts. 6db better signal margin means you use half the amount of energy. Useful for devices that run off batteries, have issues with heat dissipation.[1]

3. Less energy transmitted means your effective cell size gets smaller.

[1] Crusty old EE pointed out to me once the difference between a 85% efficient power supply and a 90% one is 65% less heat to get rid of. Same thing is true of RF power amps.
Sadly it talk against "Relational databases" instead of "RDBMS implementations".

The relational model is incredible powerfull. Maybe graphs need something seriously specializes (and indexes, of course) but the relational model do fine:

- Relational
- Key-value
- Document
- In-memory
- Search

In fact, a index (that is the thing that need to be fit for the case) can be modeled as key-value, so, as relational.

Relational won agains the NoSql in the past because is MORE powerfull, flexible.

---

What need to change, is the specifics of the implementations. And yet, relational adapt fairly easy.

In fact, just look how many stores add a sql-layer on top. Ironically, SQL is what need a easy makeovers, no the relational model....
You missed my point. What one observes in experiment can not be explained by a wave theory or a particle theory alone, or in shorter (but uninformative) phrasing you can say that there is "wave particle duality". But what is the theory that actually works? It is not the theory of wave particle duality (which just stands for "we had to use two contradictory theories" before we can find the more precise theory). The more precise theory is that of quantum fields: there are no particles and no waves, just quantum fields that in certain parameter regimes are well approximated by particles or waves.
Sure and you could buy SCO UNIX for that machine for only $3500.

Everyone knew DOS was awful, but it had all the software, and the alternatives (e.g. OS/2) were worse. Once Windows matured, adoption was immediate.
So you're saying neither (say) VirtualBox nor other GNU software qualify as open-source? They seem to fail the very first sentence of criterion #1, since they place restrictions on when/how you can redistribute the source/software in aggregation with other sources/software.
...doesn't this just reinforce that having family connections matter more? Are you more likely to follow the advice of your family or some stranger? If your family connections have insight and/or inside knowledge of markets, aren't you more likely to accidentally take good advice than the average joe? You're still not immune to bad advice, but you have a higher percentage chance of having higher quality information to act on.

Thanks. The choice of gcc was somewhat arbitrary so clang could work too. I actually fiddle a bit with lldb before this.

From your description, it sounds like I'd really ought to removing optimizations (with -O0 from what's suggested here).

For variables, local variables can be optimized out (something I recall seeing in gdb without -O0) but all global variables are still kept, right? (At least, the ELF has names and addresses.)
That's because they haven't studied philosophy. I have a background in the sciences, and what I observed is that, in terms of how they think when they are actually doing science, as opposed to explaining it to people who are not scientists, they work out of a set of assumptions pretty much the same as Pragmatism.

Opportunity costs are very, very real and very often overlooked when people give this kind of advice. For 95% if all workloads encountered by the types of people who dwell on this forum, there is zero value add in running your own data center.

One interesting thing about evolution is that meta-evolution is evolution. In other words, we see "Darwinian" as opposed to "Lamarckian" evolution not because the latter is impossible, but because there is adaptive advantage to the former. Gregory Bateson works this out from cybernetic first principles in one of his books. "Steps to an Ecology of Mind" I think. An evolving system of either kind will evolve to evince mostly Darwinian evolution.

Another way to understand this is to consider that you cannot distinguish "Darwinian" vs. "Lamarckian" in the evolution of single-celled microbes. Microbes don't grow old and die. Each Amoeba is billions of years old. (HeLa cells are called immortal.[1]) A change in the cytoplasm of an ancestor cell would be carried into both daughter cells.

In "Selfish Gene" Dawkins works out how death and birth have adaptive value for genes in multicellular species. The meta-evolutionary "choice" to reproduce by sex and children (rather than, say, budding, or metamorphosis, or some kind of mass mitosis) is "made" by the normal process of evolution, not some additional meta-process.

In short, there is no a priori reason to believe that the life of Earth has not evolved intelligence. (After all, we are intelligent.) What I mean is, the machinery of evolution itself will have evolved to be able to direct its own evolution, IF intelligently self-directed evolution is adaptively valuable.

If you want to prove that Nature is not intelligent you have to show that there is adaptive value to remaining "dumb". Given what we now know about adaptive systems, that's the only way Nature would have evolved without ambient intelligence: if it pays to act dumb.

That is an excellent question.

The answer is super complex and many factors play a role in the technical bits - if we ignore the commercial bits.

DSL lines are capacitively coupled to ground over their entire run length. This limits the frequency at which the line will operate reliably (a typical DSL modem will perform a whole series of tests to figure out which bands are 'safe' to use).

Other factors are dodgy connections in the line, other DSL lines in the same trunk cable causing interference, crappy termination causing impedance mis-match between the transmission lines and the driver hardware and limited usable bandwidth for a carrier wave to superimpose your data on top of. The smaller the available frequency band(s) the less data you can send.

Think of 'POTS' (the Plain Old Telephone Service) wiring as just about the worst possible means of transporting data that you could find. All things considered that DSL works at all is a small miracle and it took a good bit of engineering and some changes to the infrastructure (mostly the removal of the boost coils in the lines) to allow it to work.

LTE ('air' as you call it) has a huge advantage. It starts off as a GHz range carrier signal with modulation bands up to 200MHz wide (but more typically between 20 and 60MHz). That's an awful lot of bandwidth. The lack of connectivity is made up for by having a fairly dense network of base stations.

Of course you need to share those base stations with everybody else but as long as it is just you you can see phenomenal speeds, far in excess of what your DSL line is capable of.

If your DSL line could use carrier frequencies in the 100's of MHz without losing definition then DSL could be just as fast. Unfortunately the physical medium is crap and there isn't much to be done about that short of replacing it with coax (and that's called cable, and it's faster than DSL if you are on your own but - again - you will share that run of coax with a lot of your neighbours).
Wow, I hadn't realized that WiFi standards were developed like this. Looking down the page, I see a bunch of TM symbols, endorsements from massive companies, and no technical details or even attempt to describe anything related to security. Not very confidence-inspiring to an outsider.

The Google proposal does have quite a few things going for it, IMO.

The TS heap-allocates all coroutine frames by default and hopes that can be optimized out; the Google proposal treats the coroutine frame as an anonymously-typed object much like a lambda and leaves allocation (or not) up to the surrounding library.

The TS has a huge pile of extension points to control behavior; the Google proposal provides the same functionality via a single operator overload (which plays a role similar to the argument passed to call-with-current-continuation).

The TS has co_yield, co_return, and co_await; the Google proposal has a single operator that takes the place of co_await, while co_yield and co_await are made unnecessary by its interface.

The Google proposal does have some things that need to be solved, but (again IMO) it's a much more promising direction than the TS.

> Menus across the top of the screen, inherited from Xerox Alto whose portrait format monitor made vertical space most plentiful, did not make so much sense on the Macintosh landscape monitor, still less so on today's letterbox monitors

Are you proposing a NeXT-style floating vertical menu? I'm trying to envision one that either wouldn't take up more usable screen real estate than a thin strip at the top of the screen or would have to constantly be re-arranged and am coming up short.

> required clicking twice in rapid succession

To open a file you could always select the file then choose "Open" from the File menu (or press Cmd-O). Double-click was just a shortcut. Same thing with the oft-maligned "dragging floppy disks to the trash to eject" - the standard method was selecting "Put Away" from the menu.

Just as some people have trouble double-clicking, others have trouble mistaking the left and right mouse buttons. The solution isn't so clear-cut.

I usually brought my own keyboards (you can get one with MX browns or mx brown clones for $35-75 on amazon) to whatever job.. but at this one they saw my keyboard, said "Budget of $100, spec out whatever you want, and we'll order it."

The guy said "$150 for a keyboard and mouse of someone's choice, amortized over a year or two, is a tiny price to pay to keep our people happy."

I ended up with a Das 4C board at work (with browns) and a custom double-shot keycap set (bought out of my own pocket).

And they really don't need to have that as an advantage over regular cabs as their service already is superior. In my city (Sydney) I would take Uber even if it wasn't cheaper because every time I get in a regular cab they either try and go a slow way or when we get to the destination they hit some buttons and the fare jumps by a few dollars even though we haven't gone over a toll road or the time of day doesn't have a penalty rate.

I don't think this is a case of them actually judging Asian applicants as having a bad personality. There's nothing subjective actually going on here. Harvard was using the only subjective factor in the process to achieve their own goals for affirmative action.

They failed. Hopefully this blows up in their face as it should. The way to end racial discrimination in this country is to stop discriminating based on race.

I totally agree, but I like bad analogies.

There is a similar problem with Special Relativity and Classic Newtonian Mechanics. Let's pick an usual object like a pool ball. To understand it completely you must apply Special Relativity, but for everyday calculation you can approximate its behavior with Classic Mechanic and the approximation is good to play pool, throw it at a target and whatever you usually need. Moreover, you can apply all the theory of a Rigid Body and analyze how it rotates. The problem is that there are no rigid bodies in Special Relativity, because any change must affect all the ball instantly. So a rigid body is sometimes a very good approximation, but there are no true rigid bodies.

In a quantum object in some experiments they can be approximated very well as a particle, and in other experiments they can be approximated very well as a wave. But this are only two good approximations that make the calculations much easier but are not the exact behavior of the object.

I think that at the beginning of discovery of quantum mechanics nobody know what was happening and only know that some object were weird and sometimes they ware well approximated as particles and sometimes they ware well approximated as waves. Later they discovered the "true" nature of these object that sometimes can be approximated as a wave or as a particle, but it is much more difficult to explain to someone that doesn't want to learn the math.

California has tens of thousands of local businesses, and yet only one official office to police them?

Lets say I get ripped off by a restaurant, store, or local company (and I find out later after looking at my CC bill), what recourse do I have? Call the police? What are they going to do? Do they even handle financial fraud? File with the attorney general of California? Is his office really going to look into my issue? Do we just assume all companies are law-abiding? This doesn't make sense to me.

(I know you can call your CC company and dispute the charge, but that doesn't punish the company doing it, except maybe not crediting them that one charge, that is not a deterrent to overcharge your customers, there should be some form of punishment by a government authority)

I have experienced the same type of frustration and sympathize. The laws governing nature are simple and elegant, but they work at a level quite remote from the parameter regimes we experience macroscopically, so they indeed seem unintuitive.

There are many good resources online that can help (I encourage you to search for them), but the truth is that you need to spend many hours reading and solving problem sets to build something you can call intuition. I promise you, it is worth it, but there are many other things that are worth it too.

They certainly don't speak for me. In fact while I found this post interesting, and I like how the author tried to get into Traister's mindset to empathize with how he may have become misguided, I felt like it meandered into personal attacks a bit more than necessary.

Maybe I'm just sensitive because I have gotten excited about having learned something and rushed to share my knowledge, only to be cut off at the knees by the more august folks who told me I was in fact doing it wrong. :-)

But also, we've all written bad code, right? Have you ever written code that you've held your nose while writing, working under annoying idiosyncrasies of the problem domain / business requirements, and you just know at some point another developer is going to come along and read that code without having the full context of the situation, and think you're an idiot, and you won't be there to defend yourself?

While it's not quite the same situation that's the kind of empathy I'm feeling here. Who knows the circumstances that led to this book. The author of this blog post admits there was a dearth of material on learning C pointers at the time so I think Traister's heart was in the right place in trying to fill that gap, however misguided.

Great, happy to stop debating.
This dispute isn't about the probabilities or the math, it's about what the probabilities/math are modeling. Is it a non-classical wave-function woo that collapses, including backwards in time? Is it evidence for multiple realities? Is there a pilot wave or other hidden variables? Or is it mostly a matter of ignorance of the exact state of the quantum system, requiring us to use probabilities?
But this duality has never been offered by anyone as an "explanation" of quantum behavior. Because it is the quantum behavior - as directly observed in experiment; and it is quantum mechanics (rather than QFT as its relativistic form) that provides a clear explanation of this apparent duality.
