In the ideal case, the answer to your second questions seem to be obviously "yes"; the market in active managers will hit an equilibrium where their salary is paid by the additional info they bring. However, it seems clear from the current situation that the market is far from ideal since there have been too many active managers for decades. Whatever it is that allows them to persist (human overconfidence, salesmen, principal-agent problems) has not been eliminated, even if "word has gotten out" so that investors have began to develop a partial immunity against them. Knowing exactly where the new equilibrium will be requires a detailed understanding of that mechanism, which I don't think anyone has.

Poor guy... he only made $5.2 million...?
> The loss of customers and reputation should a major security concern arise

The potentially nice thing about regulation is that you can have some level of trust in a compliant manufacturer. In your example, customers don't know anything about the security of their chosen vendor until a breach happens.. At which point, presumably they leave that manufacturer (and they fix their shit or die), and go to a new manufacturer who hasn't had a breach yet, or has used PR expertise to hide their mishaps, or... maybe they are actually secure. But who knows? Customers don't have the details they need to do anything but hop about randomly between manufacturers.
Is the US even manufacturing non-military firearms at a rate sufficient for 2k/day to slip out through smuggling? That seems extraordinarily unlikely.
Yeah I think this was more of a fun-time hobby project than a serious candidate for the NBL. Quoting the note:

"This is the first language I have ever designed or implemented. There are also a lot of features not yet implemented and probably bugs not yet fixed. The interpreter is currently also just a tree walker, and not a faster bytecode vm."
Would it be worth an effort if there was an open source protocol of secure communication of IOT devices?

For example, many solutions use MQTT, why not make a secure TCP/UDP one by implementing one of the higher layers in OSI stack?
The H2O server, on the first request, sends a cookie that includes a signature of all the files a server pushes: https://h2o.examp1e.net/configure/http2_directives.html#http...

If, on subsequent requests, the cookie is sent along with the request, H2O doesn't send those files.

Video shows man forcibly removed from United flight because it was overbooked
Flying is a relatively small contributor. But as spodek pointed out, a flight can take a year's worth of CO2 emissions for one person if we're aiming for a 2-degree change. That just shows how far over that limit we are going. We're going to have to do all the big things you alluded to, but if we don't also tackle smaller things like flying less, we're still going to be over the limit.
It varies by region. In some places any tree with a trunk radius > 4" is listed automatically, for example.

Everyone blames online retailing, buy the matter of the fact is that wages still are not keeping pace with even cost of living, and more and more people are having to cut out unnecessary things in order to make ends meet.

People love to go to malls, but they aren't going to go spend $75 on a polo shirt when they have a $400 electric bill.

As wages continue to lag, this will affect online retailers as well eventually.

I'm guessing JD has lawyers smart enough to protect the company against something like this. For one, I'm guessing the purchaser / licensee agreed to binding arbitration.

This is actually a very good point. I'm from Africa and currently living in North America. It is interesting to compare and contrast my views about the value / benefit of education vs my parent's. In a lot of countries in Africa, education is a privilege (I was VERY lucky). Few can access it so it is a rather strong signal.

I do agree with the spirit of the parent comment however, in that there are a lot of false and unconscious assumptions about "Africa" held by NAers that need to be rooted out and extinguished.
As I understand it, the client has an opportunity to proactively cancel pushes of assets it already has cached.

The server will send a "push promise" which basically says "I'm going to send this file to you", and then the client can come back and say "don't bother, I already have it". And this all happens in parallel with the download of other assets (like the main page), so it doesn't really slow anything down.

Here's an article I read which goes into how server push works in a lot more detail: https://hpbn.co/http2/#server-push

> It's not only a crime, it's an extremely serious crime. What on Earth are you talking about?

Today it is. Back then it wasn't. (Or rather, it wasn't seen as such.) It was, by definition, a number that people made up based on their gut feeling (NOT hard data), and there was no regulation or precedent for what sort of number you could make up.

Notice that in the linked article, the Bank of England carefully doesn't deny putting pressure on banks to keep Libor low, and just says that: ""

Or see the article I linked elsewhere in the thread about Barclay's who was perfectly open with analysts and regulators that they were lying about Libor to improve their share price: http://dealbreaker.com/2012/07/same-old-boring-story/

Yes, we see it as a serious crime now, but it's pretty clear that circa 2007-2008, that was not a common view.

> LIBOR is a derivative of daily rate data which is shared between banks [...] You can't tell investors that the rate is based on a daily measurement of interbank risk

It's neither of those things, and I certainly hope investors weren't being told that, because that would be a lie. It's literally the result of asking some banks, "hey, if you went and borrowed some money...how much do you reckon you'd get charged?". And it turns out that's horribly subjective, not very useful, and prone to manipulation!

> This is to protect against malicious operators from getting CAs to give them certificates without authorization of the domain owner. The reason this is necessary is because the method that CAs use to validate that they're issuing the certificate to the right person is not standardized, and so you end up with a bunch of potential ways that an operator could fraudulently get a certificate that are hard to stop. I know in the past, some CAs would issue to certificates to anyone with root@, admin@, or any one of a list of privileged email addresses. Do you want email admins to be able to create whatever certificates they want for your domain? No.

I don't see how CAA protects against this. If you're using CAA, presumably your email admin could just request a certificate from one of the whitelisted CAs. The only saving factor is if your whitelisted CAs don't support email-based verification.
> The tools needed for this were pretty expensive though, and needed some expertise, as the process was somewhat complicated.

There's a pretty good chance that was done intentionally.
Basically yes. The client can cancel the streams for pushed assets that are in cache. But the server doesn't have this information (natively) when one page is requested.

As others have said, there are workarounds using cookies. Which is yet another abuse of a very bad feature of HTTP.

I would say, based on my experience that indeed it does require some level of specialization which most don't have today. I'm fighting with an IoT manufacturer right now because they ship the same root private key on every one of their devices. This is a pretty simple concept to understand:

"Are all your device privates derived from the same key? Do you ask your users to install your public root to get past security warnings?"

Yet they clearly don't understand PKI 101 and think what they are doing is completely appropriate because they are "following standards" while of course missing the bigger picture entirely.

I've been working as a contractor for the last few years, so have experience of several companies. All have them have employed people over 40 and 50, some also over-60s, in all kinds of roles including writing code and management. Generally, their experience in delivering software is invaluable, regardless of technologies used.

People online tend to under-estimate how many people over 30 are involved in tech, for the simple reason that they tend not to use social media as much.

If you're talking specifically about your current job, then maybe they expect career progression to mean moving to management. Talk to your line manager to see what the coding career path is - if there isn't one then maybe you might have to consider finding another job at a place which does have coding career paths.

" Upon unboxing an IoT device and first power-on, require physical contact (via NFC?) with user's primary smartphone/wearable, and register the device with the user's third-party cloud account (i.e. Apple's iCloud/HomeKit)."

Sorry, you lost me here. The last thing we need right now is another database of users' personal information. Why every gadget should be attached to my personal phone?

"Only allow control of the IoT device from the smartphones/wearables that are signed into the user's iCloud/Google/Microsoft/etc. account."

No again. It's enough Google owns my phone and email, I don't want it to own my home. What happens when Google's algorithm decides to ban you for no apparent reason (there are plenty of such horror stories around)?

Tl;DR if that's the price to pay for IoT security, I'm resorting back to "dumb" devices or going to live in woods.
For what I see, this is a problem for the consumer market on one side and for the small manufacturers on the other.

Nothing more than another line or an extension of home / office / factory appliances for them.

I disagree. I find that SASS mixins provide the same reusability as classes but in a much cleaner way. True, it makes your HTML and CSS very coupled, but it does provide you with a true clean separation of content and presentation.

I find

// style.scss
@mixin button($color, $size) { ... }

.download-book {
@include button(
$color: red,
$size: big
);
}

.send-email {
@include button(
$color: blue,
$size: small
);
}

// index.html
<button class="download-book">Download book</button>
<button class="send-email">Send email</button>

much cleaner than

// style.scss
.button { ... }
.red { ... }
.blue { ... }
.big { ... }
.small { ... }

// index.html
<button class="button big red">Download book</button>
<button class="button small blue">Send email</button>

1. When you change the visual aspect of an element, you go to the stylesheet and don't go adding/removing classes from the content layer (HTML).

2. When using generic names like "button", "big", "small", etc... I always find myself in a naming conflict at some point. The likelihood of semantic names having conflicts is much smaller.

Of course, your CSS file becomes a lot bigger. But when enabling compression, the stylesheets using mixins turn out to be smaller (see https://tech.bellycard.com/blog/sass-mixins-vs-extends-the-d...). Also, your HTML file is likely smaller too when using semantic classes.
...except these are going to a very small group of people? And very likely not collectors or hunters.

PIR sensors are reasonably cheap and have low power consumption. They could be battery powered and connected to a local low-power wireless network (transmitting only, and at low data rate), which would make installation easy. It wouldn't take much battery capacity to beat the expected lifespan of a IoT device. They're generally good at discriminating between humans and pets, but if a pet did trigger it the worst that would happen is you waste a little electricity or fuel as you give it some light or heat you didn't intend to. You stand to lose much more if somebody hacks your internet connected solution. And if you're laying still enough to avoid triggering a PIR sensor you're probably sleeping and want the light off. And most phones are not waterproof so they cannot be used in the shower, so IoT does no better there.

I think it's unlikely that the IoT door lock features add enough security to make up for the increased attack surface compared to the local only version.
Not all are killed. Millions of captive chickens live much longer and peaceful lives than its wild counterparts (They do not need to care for the danger of being burned alive in an indonesian fireforest for example). Many laying and pet hens die for natural causes after ten years or so roaming around some garden or farm. This is a lot of sun-bathing, clucking and scratching time to enjoy for a middle sized bird with plenty of predators that normally would not reach its first birdday. Even broilers live longer than most wild chicks.

Arpad Elo's rating system has no single defined reference pool of players. The way it works is that you take a pool of players, establish the rating that unknown new players will receive (1500 in some cases) and then the system evolves from there. There are many disparate pools of players using the Elo system for their ratings, across many games.

Just because it was not calibrated with humans does not mean it is not an "Elo" system.

> You don't think that people on the other ends of trades that depended on Barclay's Libor rate were depending on it being objective or accurate?

I certainly hope that people were not depending on Libor being an objective metric, because that would imply they hadn't the foggiest clue what Libor is or how it's calculated.

(Also, "Barclays was ripping them off" implies Barclay's was on the other end of the trade, but that's not typically what happened. A more representative example might be "hedge fund buys a bunch of mortgage backed securities pegged to Libor + some number; Barclay's lies to try and avoid going under and pushes the Libor rate down a fraction of a hair, meaning a few million homeowners pay slightly less interest than they "should", and the hedge fund makes slightly less money that it "should". Which is, sure, horrible, and people have paid large fines and gone to jail for it. But it's hard to get too outraged over it; compare it to, eg, the banks who knowingly resold bad mortgages.)
