This is my story without advice or conclusions:

10 years of lower back pain. Average of 5 serious strikes a year would take me out for 3 or 4 days completely. A feeling of weakness or mild pain occurring regularly in between those. Nothing on MRI. Lots of different Physio etc at different times. Special chairs, special cushions, Difene (diclofenac) ... too much.

Late 2016 got sciatic pain for the first time. Took me out for 5 days. Got over it. Started Pilates. Early 2017 got hit with sciatic pain again - decided to just go through it. After 6 weeks I gave in and took some very heavy anti-inflammatories. Woke up with massive stomach pains and assumed I was reacting to the drugs. Went to the hospital and was diagnosed with Appendicitis. They took it out. Spent a couple of days taking lovely drugs. Got out. Back still rough but different somehow. Took a valium just once, slept 16 hours.

Have not had any back pain for 9 months. No drugs. No special exercise. No idea what happened. My back just feels different.
I see that France dominates 2 fewer nations than South Korea. Does this number have any meaning? In a way, South Korea did better in this way.

Is this really an explanation of why manually iterating over a list is simpler than just calling a method?

Get is simpler precisely because it hides the complexity.

> Or maybe "Why aren't you using your language's library methods to loop over that list?"

What makes those methods not subject to the "hiding complexity" objection?
Popularity is only one aspect. The only thing split popularity means is that you probably don't want to make the choice with that as your top criterion. Also, people preferring A doesn't automatically mean you'll alienate them by choosing B. Choosing this default because it's more secure, in the face of a split vote, seems like a pretty decent option to me (and I say this as somebody who would've voted for the other option).

> Nicotine is a highly bioactive compound with effects ranging from being a natural pesticide in tobacco leaves to causing addiction in tobacco users. For cancer, there is some biological basis for proposing that nicotine may promote cancer based on experimental studies that have limitations in replicating human exposure and on mechanistic studies, but human evidence is lacking (Lee et al. 2005, 2012; Dasgupta and Chellappan 2006; Zheng et al. 2007; Catassi et al. 2008; Chen et al. 2008b, 2010; Egleton et al. 2008).

If people could understand what computing was about, the iPhone would not be a bad thing. But because people don’t understand what computing is about, they think they have it in the iPhone, and that illusion is as bad as the illusion that Guitar Hero is the same as a real guitar. That’s the simple long and the short of it.

Some kids learn guitar. Some kids fantasize about learning guitar. Apple makes machines that enable the computing equivalent of both of these things.

You're never going to turn all listeners into musicians, all readers into writers, all theater-goers into actors. You can't even get everyone to dance at a wedding with an open bar. Technology can play a role in getting a few more people over the line, but Alan Kay's head is way too far in the clouds for him to even see the problem that way.

Honestly, I think what he's done is dissociated himself from his own snobbery. He talks about technology failing humanity, but he's really saying he doesn't like people. He doesn't like how most people think and live. Why else would he constantly be disappointed in technology failing to turn all of humanity into always-on cultural creatives? It's like he looks at books and says, well, the dream for books is for everyone to read challenging literature, but at the beach or on the subway you see mostly "Eat Pray Love" and Stephen King, so clearly books have failed.

People are doing the same dumb shit with books and technology that they did without it. They choose passive consumption. When I complain about it, I'll blame it on technology so I don't sound like a misanthrope.

He constantly talks about creating, learning, and education, but he doesn't bring any attention to any current work supporting these activities. He doesn't say, look, here's this great work being done for kids, and it's limited because the iPad needs this feature. He doesn't say, look, here's this great computing system I use to support my own work, and it be a lot better with this specific kind of OS or hardware support. Instead of talking about how the Apple hardware is holding back current work, he's talking about how it fails to implement his own ideas from thirty years ago.

You'd think he could find SOME new idea to promote and celebrate, if only to point out what he thinks progress looks like, but apparently Apple has snuffed out every worthwhile avenue of improvement by a few unfortunate unfortunate hardware choices.

My impression (from helping family set up off-to-college computers over the past couple of years) is that modern teenagers typically have over a TB of photos shot on their iphones. And that doesn't include video. They're on track to need 5 TB of storage just for still photos by the end of their lifetime.

> We will eventually reach the limit on what the human body can perceive in terms of audio and video quality

Maybe on a flat screen across the living room. But when you have, say, 20k (~800 megapixels), you can expand the field of view to cover the entire sphere. Add in computational photography that allows refocusing and a (limited) amount of movement, and there is the potential for amateur-shot video to soak up any amount of storage you can buy.
This has always seemed to me like an obvious setup for anyone with enough solar capacity to routinely run a surplus - particularly in states where the local utilities have purchased legislative support for near-punituve connection charges or effectively zero rates for anyone interested in selling surplus power back into the grid.

Edit: Not an outdoor setup but a setup to use all electricity surplus to regular needs for mining instead.
If artists don't get paid directly by sales to consumers absolutely nothing bad will happen. Society will have an abundance of artistic output and artists will find ways to monetise their art anyway. Don't pretend otherwise.

Well, when you put it that way..."
At the heart of every mechanical watch lies a coiled spring. Within that spring energy is stored that wants to be released.

This energy is released through the wheel train, which is a set of cogs with reductions (some of them attached to the hands).

Left to its own device this system would just spin as quickly as possible until the spring is unwound.

To prevent this, somewhere in the train there is something called a lever escapement. Simple put, this puts a stick in a cog at regular intervals to prevent it from spinning and unwinding freely. This stick is timed by a weight that spins from left to right. This stick literally is what makes watches tick, since that's where the ticking sound comes from.

Spring Drive doesn't poke a stick into a wheel to prevent the system from freely unwinding. What it does do is add magnets to the wheel and stationary coils around it. The wheel can't spin freely since it has to overcome the magnetic induction as the magnets pass the coils. That's the reason SpringDrive doesn't tick and the hands glide instead of stopping and starting.

If it's still unclear, try looking up escapement levers first. There should be a lot of clear animated explanations online.
Ah, good catch, and this is why I should wait for caffeine levels to peak before screeding.

At work we have a lot of customers now, many of them with large security orgs. Their approaches vary a lot, presumably because of their experiences and security maturity.

Beyond a certain level, there is always a security org and quite typically it has veto powers that override any local manager's budgetary concerns. Whether that veto is applied well is quite distinct from the way it creates a ceiling over potential spending on features.

That all said, I agree that there are fundamental properties of security that will cause it to be consistently under-attended relative to what a more actuarial or financial model would suggest is rational. It is only observable in its absence, but most feedback systems -- formal or informal -- rely on observable signals. Market releases may lead to a juicy bonus at many companies. Invisible improvements won't.

I've thought about this a lot in the past few months and published a bunch about it internally at Pivotal. I'm not alone, of course. We're streets ahead of many vendors, but I also feel we're only getting started on the deeper and more difficult process of blending it deeply into our cultural DNA. It's a culture which believes in doing the right thing, but also a culture which detects vetoes as faults and routes around them.

Interesting times.

I'm not sure whether it's comparable, but Chris Squire from Yes spent months "hibernating" in a hotel after a bad trip with homemade acid:

“I’d had lots of good acid trips prior to that. But I made the mistake of trying some acid some friends of mine had homemade. That knocked me back, and I did sort of hibernate in an apartment in Kensington and spent quite a few months — maybe as much as a year — just playing bass.”

It doesn’t clearly show the mainspring, however at around 10:45 you can see the small gear spinning. That is being driven by the mainspring, and if you removed the escapement it would spin super quick until the mainspring was unwound.

It’s the constant rocking back and forth of the regulator that limits the speed that small gear (called the escape wheel) can rotate, therefore limiting how quickly the mainspring releases it’s energy.

> The majority of people don't want to be on pills.

Well I'm sure that even the addicts don't "want" to be on pills. The real question is how many people actually are unnecessarily addicted. Do you believe that most are not? If so how would you substantiate that? If you want I can start listing out anecdotal information that would support the opposite of what you are saying, but that would get us nowhere right?
I thought it was a PA jingle .. crazy.
As someone who's worked a lot in support and has been out of it for a while now, this article utterly misses the point and reeks of whining and excuse-making.

Anyone who's spent time in the support trenches knows that the rest of the company has contempt for them and doesn't know what actually happens on support calls. Getting everyone to do support, at least for a little while, shows what kind of problems support people encounter, both technical and social. Developers in particular see support staff as below them, not equals, and without any CS experience they're often clueless about what goes on in CS - they get a bit more empathic when they've actually seen what happens.

It was actually laughable when the article talked of CS being considered a finely-honed skill that takes years; I can guarantee you, that's not how anyone treats support staff. No-one ever talks of a concept like a "10x support staffer".

In any case, CS is like hospitality: it's an unpleasant job that can be done without much training, isn't well-paid, and few people like it or want to stay in it long-term. It's that unpleasantness which is the real reason why the author doesn't want to do it, not some supposed passion for high-quality CS.

It would be analogous to a security breach of a manufacturer's database of keycuts and corresponding locks, not outright refusing to lock your doors.
I'm sure someone will pipe up with a more exact answer (likely using permutation and/or combination in their specific mathematical senses), but I believe it's because summing medals is algebraic, and with the given weights there's no way for the sum of any combination of non-identical medals that equals any other. The values of 𝛑 and 𝛑² (and the patient, unacknowledged workhorse 1) provide this. Looking at a simple case where s is the number of silvers and b the number of bronzes, there's no value of b that can equal any value of s·𝛑. You could use another triple of weights, such as (𝛑, e, 1) as well.

Having spent a great deal of time - most of my career, really, doing performance optimization, some of this rings true, but much of it doesn't.

Rule 2 only applies if you can just decide that your current level of performance is "pretty great" and then parachute away to another project. Otherwise if you find that, instead of 1 hot spot taking 80% of your time, you have 5 warm spots taking 16% of your time, you have 5x as much thinking to do to fix your problems and get that potential 4x speedup (assuming you could get cut that 80% down by a factor of 16).

Rule 4 is an argument from bad implementation. It's harder to get fancy algorithms right, but what does it mean to say an algorithm is buggier than some other algorithm. Are we seriously meant to think that there are some bugs buried in Strassen's matrix multiply?

Rule 3 is dubious. It seems to imply that the performance cost of fancy algorithms on low N matters, which assumes that we are actually executing the algorithm quite a bit. Perhaps we've picked the wrong fancy algorithm? Maybe if you have a godzillion tiny matrix multiplies you shouldn't be using Strassen's but you might still get a performance win from doing something 'fancy' that's tuned for large numbers of small matrix multiplies...

As for Rule 5, this is probably the best of the lot. That's why I like to use languages that allow me to describe my data structures in detail... even going so far as to say that the contents of my user-built containers have types. Ahem.
> I understand how this whole idea got started — customers are the lifeblood of any business. And keeping communication lines open between customers and the entire team is definitely important.

^^ This right here is one example of the article missing the point. It doesn't even have internal consistency - if the devs only spent their first month doing some CS as the article states, then after the first month they don't maintain those supposed open lines of communications.

I think Amazon is trying to shift away from that approach with the push to get a "Game of Thrones" type show on Prime Video.

Here's Stratechery's take on it:

> ... focusing Amazon Prime Video on massive hits that break through into the popular consciousness rationalizes the service considerably. If the ultimate goal is signups, then by definition producing shows that everyone is talking about is more important than building out a fleshed-out content library. Netflix has to worry about having plenty of content to keep people coming back; Amazon has the rest of Prime to accomplish that.

That's what I came here to say. It's a selective COX-2 inhibitor so maybe you could argue it's like celecoxib (which is prescribed for some types of pain, mainly acute). The point being that back pain and most chronic pain isn't really inflammatory, save neuropathic pain.
Right. That analogy it more correct, but it doesn't make it follow logically. It's like a someone having the keys and address for each key.
It does. Locking your house provides some security.

But it would no longer provide security if every person in the country had a copy of your key.
Thanks for that.

The middlebrow dynamic has to do with assuming one knows more than one does and trying to constrain the spectrum of variation. Since unexpected variations are often the most interesting, that is a big bad deal.
I dunno about the engineers where you work, but a lot of the game programmers at (name witheld, but pick any company. They all seem similar) are not good with interpersonal soft skills. Granted, I didn't read the article before looking at the comments (helps me weed out articles that are a waste of time), but most of our engineers (myself included) would just walk away from the CS role on tilt having learned nothing more than to be grateful they don't have to interact with any people, much less people who have gotten angry enough to contact CS, as a means of making their living. Maybe I'm completely wrong and I just got unlucky with myself and the engineers at the 3 companies I've worked at with programmers, and they really do enjoy confrontational human interactions. I've been wrong before, but the stereotype fits pretty close, though exaggerated, with my experience.
That's a different argument, than the one in the first line, to which I completely agree.
