> If this involved 2700 tons of ammonium nitrate, does that mean it was the equivalent to 2700 tons of TNT?

No, because ammonium nitrate isn't equivalent to TNT. Various sources give the REF of Ammonium Nitrate as 0.42, so at most it should, by itself, be equivalent to 1134 tons of TNT, but the actual explosion could be less because of inefficient ignition, or more if it set off something else that added to the explosion.

I am on the older end of Gen Z and have noticed the opposite. Snap was cool from 2014 until 2019 but now Insta has a slight edge. I still use both but it varies by whom I'm talking to: some friends I talk to on Snap and some I do on Insta.

Nuclear weapons span a huge range of yields. The W54 yield was as low as 10 tons, about as energetic as a daisy cutter conventional bomb.

We're talking about a huge web framework here. Your comment might apply to small isolated pieces of code. But Django is built on top of thousands if not millions of abstractions. It's absolutely unreasonable to think that it won't change.
One might argue the consumer doesn't get access to products that could be superior due to incumbents choking out innovators (like saplings trying to grow in a forest below mature trees blocking out the sun).

In addition to the higher ad costs leading to higher costs for the consumer and the resulting funneling of those consumers to only a handful of outfits, a major point from the article is the "Smart Campaigns". Google is exploiting small businesses' lack of marketing expertise to push them, often persistently, to using automatic, algorithm based targeting instead of manual keyword targeting. The result is that a lot of the money they put up for advertising goes into a black hole devoid of useful exposure due to the useless keywords that the algorithm picks for them.

They're not just being outbid by larger outfits, but are being lead to believe that they can compete with said outfits by using Google's "Smart Campaigns". Google gets the money from both, but one is being relegated to space that leads to nothing.

Good link. Relevant part on TAS from the link:

One way of facilitating this demand has been the introduction of trading-at-settlement (TAS) orders. TAS allows market participants to buy or sell relative to the daily settlement price before that price has been determined. Over the years, TAS has been associated with several efforts to artificially influence the settle. Exchanges respond to these signs of manipulation by stating that such trading activity will be subject to disciplinary action. But why does an exchange even offer an order type that at the very best can be used as a tool for market participants to walk away from their responsibility to negotiate a fair price?
Thank you! This is correct. We understand there are concerns about Electron (some legitimate and some religious), and we've built this app with those concerns in mind. The backend is Rust, with the arguably most critical components (encryption) being open source libraries (ring). - Ben, 1Password
Those trusts earn their money by investing it in enterprises that actually create value through the use of many employees.

I'm not convinced of TS as of yet for my needs. The vast majority of bugs and complexity in UI code seem to come from state management, asynchronicity, complex validation and the like. Static typing doesn't help with any of these or at least not to a degree that is sufficient. TS also doesn't seem to help at all with performance, which I find to be the most important trade-off for introducing types and the implied complexity.

I'm heavily biased towards small teams and small to medium programs though. I can at least imagine how TS improves ad-hoc documentation in some cases, which can definitely help in the "maintaining the code over a long period by different people"-scenarios.

> Who was it that turned GC off entirely, minimized allocation and just restarted their VMs when they ran out of RAM every couple of hours, was that Netflix?

Every single financial firm out there, using Java for sub-microsecond tasks. Really, there is no other way to keep low latencies if you have your GC messing around every few milliseconds.

This may surprise some people, but Java is ubiquitous in low latency environments such as trading firms. It offers performance close enough to C++, but the developer pool is way larger. Also, when one needs to comply with extremely low latency requirements, the way to go is always dedicated hardware anyway.

If you are interested in the topic, there is this project called OpenHFT that aims to provide high frequency trading tools for Java. Particularly, their Chronicle Queue implementation tries to handle the GC latency issue by storing stuff off heap. Its co-founder, Peter Lawrey, has also delivered a handful of good talks about low latency Java.

Thanks for the paper. The data tables for it just proves my point. For example, in the binary-trees test, Java used 1120 Mb. Go used 228, Rust used 180, Lisp used 373, Haskell used 494 Mb. Only Jruby and Erlang seem to require more memory usage. If a webapp performs similar to this experiment, I could rewrite it in almost any other language and I’d cut the required number of servers in half or more.

People aren't going to do that, though. There's not enough people that understand the issue and are willing to work through the problems to use Firefox.

This is a classic case of chasing after the ideal solution and ending up nowhere instead of making a compromise and actually improving things. It would be far better for everyone if Mozilla used the Chromium engine and built features on top of that like Microsoft is doing. Instead they are putting massive amounts of effort into a rendering/js engine that will always be "broken" because it's not exactly the same as Chrome.

If not for the racial context, what other motivation would there be to change the terms? In what other context would someone object to arbitrarily assigning one color as good and one color as bad? Had they historically been called bluelist and purplelist, I do not think anyone would honestly argue that there would be such demand for changing the names.

It's also unproductive on your part to say that we can't make safe assumptions. The post that I replied to mentioned that people don't like the terminology because it relates white to good and black to bad. That is obviously a response to the racially charged times. To claim otherwise is to lie. I find it doubtful any major tech companies (or anyone for that matter) were discussing changes these terms because they are more "semantically explicit" before 2020 and were not doing so in response to some ill-assigned racial undertones that do not actually exist.

As far as jumping the gun, it is not as absurd an argument as you are characterizing it to be. People do seek control the context in which white and black can be used. The terms whitelist and blacklist are generally accepted and people have little trouble deducing their meaning. Colors do have cultural meaning outside of race - brides generally wear white dresses, people wear black to a funeral, black ties are considered formal, etc.
Theres seem to be a hardware button to turn these on and off. The solution should be simple:

Good point about heat waste disposal. That's why you almost always see nuclear reactors along lakes/rivers/oceans, which is bad for other reasons as we saw with Fukushima, and all of that hot water being released wreaks havoc with riparian/marine ecosystems. Nuclear has downsides beyond the most obvious one, that of the risk of fallout.

> I think that fission is not a good fit for terrestrial power.

Heh, it's even worse off-planet. If you think dumping the waste heat is hard when you have access to an atmosphere/large bodies of water, wait until you try it when you don't!! ;)
I certainly don't think there are right and wrong answers here, btw.

> while I am certainly no security expert

While this is the circulated wisdom, I would respond:

1. This idea keeps us from ever learning how authentication works. "It's surely too hard". But by delegating it to complicated framework abstractions, we tend to guarantee that we never know how our app's authentication works.

2. Authentication can be surprisingly simple. Seeing it in the code is a feature. Maybe, "oh, it's just res.cookie('token', securelyRandomNumber())" vs. "hmm, I hope someone writes a blog post about how Ruby on Rails' Devise gem works!" or "I hope the framework's authentication wiki pages answer my exact question!"

Frameworks sometimes make simple things complicated. I remember a common Rails/CodeIgniter question was how to redirect the user to the page they were viewing once they log in. That should be trivial. I think Devise eventually got a "redirectAfterLogin = true" config option, but that's kind of my point -- "I hope the framework thinks of my use-case" can be an unpleasant game to play.

Of course, there are always trade-offs. I reckon I've simply been burned enough times, perhaps more than you, to prefer erring on the other side for a change. After after 10 years I do prefer it.

I can imagine truly horrific bespoke hand-rolled frameworks that you probably have in mind. I won't defend those, haha. This is probably one of those things where your preferences are determined by what just happened to burn you the most so far which is most likely a coin flip.
Don't own a Tesla, and am just going from memory. I believe the "pet mode" was implemented the same time the interior protection feature was. So the pet mode was a user option to allow the car to be kept at a reasonable temp for pets / kids, whereas the interior protection feature would automatically kick in if it got too hot regardless of what the user wanted.

That's not how I read it. GP's #1 says that you're already saving $25 just looking at the cost of parts because the panel is about the same price as a traditional head unit and then there's the wiper switch. (Maybe you're right though, that they're not really saving on the switch.)

But then, #2, you factor in the cost savings associated with simplified manufacturing (which, as GP explains, goes well beyond just the wiper switch). This is what makes the panel approach much cheaper.
This is the right answer. Substraction is accurate, as much as it can be given the its inputs. It’s everything (combined) leading up to it that isn’t.

Pretty sure Instagram won the Snap battle when they copied stories. Not sure who still considers Snap a major contender in the long run.

I wouldn’t say Instagram is fading. Just that Tiktok is keeping the younger generation away from it. Snap is losing on both sides because of them.

You don't even need them to be big, even a low budget car's infotainment touchscreen is enough. Mine has adaptive brightness, so it means that at night in a dark road it'll be at lowest brightness, with black/gray, which makes it even less visible.

Facebook is always there for people but it is not the talk of the town any more.

A decade ago you could have everyone on it for their entire lunchbreaks, deep-stalking their mates. But nowadays people are not engaged with it compulsively.

Younger people don't use it because their parents are on it.

Content isn't made by people for Facebook because it won't show in their friends feeds.

Advertisers that are small to medium size businesses don't get a return from spending their money there, so they have left too.

Before Facebook there was the printed telephone book and the Yellow Pages. People and businesses had to be in the phone books because someone might want to contact them that way. But the Internet and email came along. Facebook is a bit like that, people are there but no more engaged than they are with a printed telephone book.

Facebook bought WhatsApp and Instagram to keep the same eyeballs. Because of that Facebook are successful.

But TikTok is the new, cool app in town. 80 million users in the US apparently, not all of them teenage girls.

Youtube is likely doing the same thing. It just have the political sensitivity to not state it out loud. And honestly, come on, every entertainment platform does that, range from roadside stripper house to movies, whether it is desirable or not.

They saved $25 in parts on the wiper controls. They saved more on labor. They also saved parts and labor on controls for AC/heat/fan controls, mirrors, driving mode selection (comfort/sport), traction control, regenerative braking, heated seats, and probably a bunch of other things I'm missing.

For the wipers specifically, putting it in the screen is questionable for safety reasons. The rest of it definitely saves them money.

Why Does Apple Still Exist in 2020?

> So to go back to my question, if it's actually the people

> who support this, do you consider them the enemy too?

It's a tough one. There's a lot of misinformation and propaganda out there in China and until people have a balanced idea of what the various truths are, I don't know if it can be held against them. They are likely told that they are all extremists from the only authoritative source they have available to them, you can understand why they hold the views they hold (even if we would agree they are not nice views to hold).

That said, there are people out there that hold extreme views I don't agree with (in many different social circles/cultures). As long as they don't act on these ideas and are able to be productive members of society, then it's enough to agree to disagree.

In general we need a better approach towards radicalization, and for that in my opinion we should try to solve problems internally first. Western society for example has extreme far-right and extreme far-left minorities, it's not yet clear how we step these people back from the edge (i.e. violence).
I don't think that's true. We had the same construction problems in the 70s when we wouldn't have had such a shortage. There are tons of super smart people working on nuclear startups right now, with big funding.

It's all bad management, bad execution, and bad promises. And since few of any around the world have been able to keep construction promises recently, it may just be part of the natural variability of the construction process. And 2-3x variability is not a desirable trait for $10B projects, where most of the lifetime cost is in the upfront construction.

This is just a branding thing though right? We've had all sorts of social networks that each rise and fall. If Facebook has the formula for a successful network and can apply that formula over and over again that's pretty successful.

Facebook is probably the the company most able to claim to have achieved this, with facebook.com and Instagram being two big hits, arguably Messenger and WhatsApp too. TikTok is probably the biggest sign that they have actually failed to hit a 3rd generation.
Sorry. My context here is cable boxes, which do communicate bidirectionally and somehow take even longer than DVB receivers to change channels. If you're actually receiving everything all the time, then there are other things you can do to make channel switching not take ridiculously long.

This is absolutely not true in the United States. Therapists are licensed in each state and it can cause severe professional problems and ethics situation.

FB also has a Stories feature as Instagram, in turn from Snapchat, but I barely see anyone use it while everyone and their cat (literally) use Instagram Stories.

Also, FB took a more advanced friend list concept from Google+ but few use or know how it works. (Like how “Acquintances” are your friends but they are pushed down by the algorithm)

It is apparent that it’s hard to just shoehorn different usage patterns due to different social cultures evolving on the respective networks. Let’s see how they do this time...
This has happened to me multiple times as well.
I think there's so many ways to connect on the internet that every social app has it's own role and purpose. Everything is fading away as users age and their preferences change. On top of that there are always new apps which are trying to attract new users and lock them in until something new doesn't come out that's why Zuck was obsessed with competition. He tried buying Twitter and Snapchat but they refused on the other hand Instagram and WhatsApp gave in.
