Again, maybe I've had more bad managers than the average (in my 17 years of professional experience I've had 2, maybe 3, good managers), but there's no guarantee that will happen.

Maybe in areas like SV, where good professionals with solid experience have no problem finding another role and companies are actually trying their best to keep good employees that happens more often. What I've seen is people skipped for promotion in favor of the manager's son friend. Or in favor of someone "recommended" from above. Or many other forms of nepotism.

I've seen wonderful managers-to-be being kept in a lower role because the company didn't want to cough up the increase in salary. And, as said before, invariably I've seen these people end up leaving and going somewhere else, causing the department a few problems (organization, lost know-how...).

BTW, reading my comments on this one might think I'm bitter and maybe I am: I worked 6 years in Spain and France, where nepotism is the norm and techies are considered second class citizens. I must say that I don't think I've been skipped for promotion many times and personally I haven't had many issues moving up (and down) the ladder in all the places I've worked. But I also know that one of the reasons for this is that I've never had a problem with getting up and leaving a company if I wasn't happy.

Not really. Tesla's dream was to set up a resonant field around the globe with a few giant base-stations that one could tap into at will to draw power. For many reasons that was an absolutely un-workable proposal, the major ones being that nature put up a roadblock or two on the way to getting that to work on anything but the smallest scale.

For one there is this thing called a power-law which required the voltages to be significantly higher than those needed to make a system like this work in a laboratory, the other is the breakdown voltage of the atmosphere, which causes any voltage in excess of this to return to ground, frying whatever it finds in its way (think lightning).

It would have made for a hell of a display piece.

Of course this does not stop Tesla groupies from claiming the government suppressed the design.

On another note: regular radio frequency transmitters put out enough power that so called 'crystal radios' can be powered by the transmitter directly. So in a way 'the system works' but the amounts of power that you can draw from it are minute. Tesla claimed that you could run regular industrial machinery from his technology. There is a funny parallel between the Tesla story and uBeam, the dreams are remarkably similar. 'Wouldn't it be a good thing if wireless power with substantial power transfer existed?'

There's the fourth option of not judging yourself on whether you are a good programmer or bad programmer but instead just trying to become better (which I think is essentially the conclusion eventually reaches).

It's the shift from a fixed mindset to a growth mindset a la Carole Dweck. That is quite a tough shift to make however when you've been conditioned with lots of feedback from school and university telling you are good and then suddenly that feedback disappears when you start work. Indeed I imagine most programmers aren't actually especially good when they first start - certainly if I looked back at the code I wrote 10+ years ago, I'm sure I would cringe.
A typical RFID chip has nearby a coil that is used to temporarily power up the chip using regular magnetic coupling using a (relatively) low frequency.

That same coil is then used as the antenna (at a much higher frequency) to transfer a little bit of data.

So yes, it's fundamentally different, the article describes energy transfer using radio frequency waves alone.

Do you speak from direct knowledge, or is this a deduction you're making? I can't find any clues in your profile or other contributions, so I don't know whether this is your area of expertise - in which case I would bow to it - or if it's something you've deduced from other reading. The reason I ask is because your assertion is at odds with my understanding.

My understanding is that most small mutations lead to no apparent change at all, hence the robustness. Some small mutations lead to catastrophic changes, as do almost all large mutations.

But some small mutations lead to noticeable changes in the phenotype, and those are the ones that then get selected against. Some of them are beneficial in the existing circumstances, some are not. But the point is that it's small mutations that lead to a comparatively large change in the phenotype.

And that's my point, which you echo:

Yes. Current "genetic algorithms" don't actually do anything like the systems they have been inspired by. I wonder if real progress would be better if the implementations were more faithful.

In New York the signalling system on most lines is ancient. The L train has a CBTC signalling system and it has real time arrival information. The 1/2/3/ and 4/5/6 have had upgrades, though not to CBTC, to provide similar countdown clock functionality. The 7 train is undergoing work to install CBTC.

On other lines, my understanding is that the signalling system doesn't know which train occupies a block, just that a train occupies the block. Which block is occupied isn't sent to a central control center either.

So "there's a Brooklyn-bound train 2 stops away" is the best it can do, since it can know based on which side of the tracks the train is on where the train is going. It can't know the letter or number.

The press have been bad-mouthing our cars recently based on the fact that they explode violently if they crash.

Are they super-duper safe? No. Will driving our cars grant you immortality? also, No.

But no car can promise this, and driving any car inherently runs the risk of dying - No car is provably 100% safe! If you're really worried about this, just don't drive!

Most car drivers won't care anyway, very few people crash their cars on a day-to-day basis, so it's not really relevant.

That's what the author did. That's the entire point of the article.
This is interesting. It's the kind of topic that can easily be interpreted as anyone into their pet big issue and/or worldview, dangerously so.

This could be about The Plight of The Middle class and the cost of housing. Are we really returning to a world of boarding houses? It could be about a less is more world where people are discarding processions, home and contents and living a smaller, more environmental and simpler existence. It could be about demographic and cultural shifts. More single people. It could be about the decline of extended families, communities and multigenerational households. The continued accession of cities…

Anyway, interesting.

Beyond anything else, I think this points at how much of any issue housing is these days. Manufactures goods have dropped in prices for generations to the point where looking back a few generations to a time when cutlery and crockery, salt and other things were wealth is ridiculous. Transport has improved more slowly. Air travel has certainly become a lot cheaper and international travel has become more accessible over the years. So have services like restaurants, gyms and lots of recreational goods. Information has been revolutionized. But housing, it's not really improving with time. We're not better off than our grandparents in many cases.
It's not really map+reduce.

Transducers arise out of realizing that transformations between (possibly infinite) lists can be encoded as a "reducer transformations", "transducers". When you work in this encoding you automatically get lazy transformation (since everything goes through a function call) and the avoidance of intermediate data structures (since everything goes through a function call!).

Moreover, there's a neat property of this encoding, a CPS encoding, which is that function composition still "works", it just works "backwards".

I really am not a fan of the lack of versioning, even with that explanation. Of course diamond dependencies are a problem. But they haven't actually fixed that problem; they've just declared a method for picking one of the two dependencies that is ill defined ("whichever one you happen to have pulled in first"). At least with versioning I get told that there's an incompatibility in the expectations between two libraries.

With Go's removal of version numbers, they haven't removed any of the complexity of resolving incompatibilities, they've just hidden the fact that there is one. I would have much preferred a strategy of maintaining version numbers, and resolving them via "either you specify what version you want pulled in, or we'll build with the most recent and throw a warning".

> An affordable alternative... for single people without families. You can perform most of the basic functions of life, but reproduction is a major one, too.

For what it's worth I've lived a very happy life as a kid in a 2-room apartment, in about 70 sqm. Granted, I used to spend most of my time in front of our apartments' block, playing with other kids. If it matters I grew up in Eastern Europe.

What I wanted to say is that resorting to "but would someone think of the children?" in this kind of situation in order to mask the harm done on the environment because of McMansions and huge houses in general is the wrong way to do it.
“Spiral of Revenge” – Aamulehti
How can one even remotely think that an app like Telegram can be secure, as long we know the very platforms it's running on are hackable (there are more than enough 0days on the market)?! Yeah, maybe it's expensive and a bit friendly-fire-ish to target platform holes on a large scale, but still...

My bet is that the real bad guys always use face2face when possible, and voice/video with codewords and visual cues when there's no other choice... and maybe an encripted sdcard carried by hand/mail when they really need to cary large volumes. They can't be stupid enough to use anything else for such high risk stuff!

I'd guess that the only people actually depending on good consumer-lever crypto are whistleblowers, anti-goverment protesters and individuals and companies that truly value their privacy for one reason or another! Are these the people we want to hurt here?!

Here's the difference between GA and GP

In this case it's GA, so your genome directly maps to characteristics. So (let's say) chassis density is N bits. Mutate the MSB of that and the change will be big

GP on the other hand would "build a car". And what usually happens during evolution is that some aspects gain resistance to mutation through some form of redundancy. So instead of Chassis density being a number it might be a crazy math expression that is not affected by small changes.

Also a lot of "genes" have no effect on the final product. But having a bigger genome (in this way) effectively lowers mutation rates.

It is "junk DNA" but actually has a purpose

No, it doesn't really make much sense.

The diamond dependency problem only happens when two indirect dependencies are identical but on different versions and that these two versions are incompatible. That's two big if's. 99% of the time, it's not a problem.

Notice first that this is a pretty rare problem since libraries tend to be backward compatible these days. And if you happen to come across a bad behaved one, you simply exclude the one you don't want from the graph, problem solved.

This problem has been fixed in Maven for almost ten years now, the only reason why you would not implement this crucial feature in a version manager is laziness.
Well, in Clojure they solve the problem that the standard functions are inefficient when you chain a bunch of list manipulations together (because they all return lazy lists) and neatly sidestep the fact that Clojure doesn't have generators.

That's completely incorrect: it's trivial (and common) to just ignore errors in Go:

> just trying to become better, which I think is essentially the conclusion eventually reaches

Yes, though there's a lot more detail to it than "just trying", mostly about good ways to get there: shortening the feedback cycle of improvement through peer feedback, getting past the fear of failure by lowering the cost of mistakes through blameless review. And that "being smart" is the wrong criterion, which I think is the "growth mindset".

Organisations are about politics and status. As a sideline, sometimes useful work gets done.

>In that scenario, Adam has not done a good job as a manager, and he's definitely not a good leader.

One difference between good and bad management is that good managers understand politics, they understand people, and most of all they understand the consequences of different political options. (I mean effective and ineffective, not good vs evil.)

Effective managers don't - ever - rule by formula, campfire or sports coach platitudes, or read-it-in-a-book business mythology.

So if you're dealing with someone who does any of the above as a first choice, they're unlikely to be making rational choices, or to have any deep understanding of the team(s) they're managing.

Evil managers can have a good understanding of consequences but their choices will be designed to increase their own income and status at the expense of their team/company. So they can appear to be doing stupid counterproductive things, but in fact they'll likely be promoted because they're gaming the system. They're a horror to work for, because they'll exploit their team as a resource and discard it without looking back. (I've seen people boast about this. It's not hypothetical.)

Good managers have an interest in developing the talent in their team as well as shipping good things and getting themselves promoted. But they won't be doing it with platitudes like "Leave space for people to act like managers" and then punishing anyone who actually does. They'll be more politically adept than that.

The big problem for employees is that politics and culture are invisible. I've seen plenty of management books, but I can't remember seeing a useful book that explains the practical differences between exploitation/support and good/bad good/evil management. Simple metrics like hours worked are a start, but a bigger picture with standard examples of management practices and styles, and supportive/unhealthy team cultures would be very useful.
