I've been doing Crossfit since December and wow.

That manifesto I just read there was pretty scary and cult-like, complete with totally off-topic jabs at socialism and uh, science?.

I'm having a hard time reconciling that with what my wife and I have experienced at our local Crossfit gym, which has been among the most supportive and pressure-free experiences I've ever had in my life.

To be honest, nobody's ever even mentioned diet to me there and I'm pretty overweight. The Crossfit diet seems to be low-carb, high-protein, high-vegetable which frankly is very sensible and not exactly extreme.

One thing I'd been warned about before doing Crossfit was that they don't always teach proper form for weighted exercises and that therefore there's an injury risk. I've been very wary about that. But the instructors at my gym are super responsive and proactive when it comes to my form. High marks there.

As others have said, Crossfit gyms are independently operated. Culture is going to vary by gym. I suspect (like anything else) the gyms that garner the most attention are the ones that are kinda on the fringe and not the majority where you go do fun/grueling workouts with a supportive community.
This is an insightful comment; had this happened in a western country (which it easily could) people would have gone "hey - that's how the world works". But since it happened in China with the current sentiment it is a different story ...
There is no money in that.
Everybody wants to live a lifestyle that presently requires burning fossil fuel, buying electronics, using plastics, etc. Two possibilities:

- technological advancement lets everyone indulge in this lifestyle without those externalities, or ones that are worse

- people voluntarily dial down their consumption (of food that has flown from across the world because it’s not in season, of electronics made with rare earth metals, etc), travels, and so on.

Both seem extremely unlikely and it’s hard to keep hope.
I agree with you but I fear we are in the minority, because Average Joe wants fast with shiny wheels, and is completely ignorant or complacent about some esoteric idea of a right to privacy.

Something something get what they deserve.
I have the greatest respect for gymnasts, because they are basically top of the heap for pound for pound strength. It's not an area of expertise for me though, so please enlighten me: if using momentum to get a kipping muscle up and then gradually reducing the momentum assist until you can do it strictly isn't the right progression, what is?
> music stars to earn their money in the concerts they sold out due to "piracy" and not from selling CDs

this is not entirely true; musicians also earn a significant amount of money based on how many times their songs are played on streaming services like Spotify.

Hasan Minhaj had a bit about this in Patriot Act, explaining that this is the reason artists like Li'l Pump are releasing albums with dozens of two-minute songs—shorter tracks means more plays means more $$.

What this means, and what trips me out about using Spotify (or even YouTube), is that I literally can't listen to music on their platform without putting money in someone's pocket. Great for artists I love, sad for cultural curiosities I want to understand but decidedly don't want to support, like Li'l Pump or Chris Brown.
I did CrossFit for 5 years and a shoulder surgery and visited about 30 gyms during that time. What you’re saying isn’t disingenuous but it’s thoroughly idealized and unrealistic.

Workouts with high volumes of technical movements are regularly programmed. RFT workouts with 60 snatches. High volumes of kipping pull-ups. Form goes to shit when you get tired, period, whether you are running or snatching, but being on a clock does not lend itself to slowing down, setting up right, and doing a technical movement with good form. It’s completely antithetical to it.

The coaching quality at CF gyms is widely varied and in my experience most of the folks regardless of their great intentions have no business coaching that many people doing that many complex movements.

There are much safer ways CF could be doing things. Ditch snatches and kipping pull-ups for a start. Snatches are dangerous when done improperly and kipping pull-ups are specifically bad for shoulder joints in individuals who have not built up enough strength to do several strict pullups.

Two things stand out to me as startling/interesting.

First, CrossFit is sort of presenting FB as a public health threat. Obviously it is, but I don’t hear a lot of entities make that argument.

Second, CrossFit is doing a role reversal, saying that they will place FB under review, they will decide if FB is an appropriate platform for them. In a way, they’re assuming a dominating position (yes everyone knows FB is bigger/stronger, but you can still scare bears off by shouting and looking large, and even weaker players can find upper hands or shift position). That’s a strange take on receiving FB’s perceived abuse that I have not observed before.

I have mixed feelings about this. My gut feelings here are:

1. Randomness in general is fine. Magic: The Gathering packs or blind bags or Kinder Surprise eggs should not be banned[1]. Plenty of digital games do have random drops too. If I pay Blizzard $15 per month for WoW, I can kill a dragon once per week, which has a chance of dropping an item for me, which has a chance of being a cosmetic appearance I need to complete a set. But that's fine, I think. (Right?)

2. Loot boxes in digital games are...fine...ish? I don't think Overwatch is a huge problem. Some titles have done this in a way which is fine, but overall it does feel a bit scarier than the things in example 1. (Although it's not always clear how it differs from the WoW example...)

3. In some cases, we have figured out ways to weaponise this in very dangerous ways (eg, kompu gacha). If you then target children, which some do...it's not good.

4. This is a very effective monetization technique. But to put it another way, it's a way that developers can obtain the resources they need to make good content (and there are many F2P game which do have good content!)

5. ....but those resources come from whales, and while some of those are just wealthy individuals with eccentric hobbies, others are what we'd call in other contexts "problem gamblers". "I get a cool game for free because other people have gambling addictions" is not a good argument to be making!

6. I'm reflexively skeptical of the governments ability to regulate things like this well, because it's fast moving and highly technical. There is every incentive for a company who has perfected a new more effective technique for exploitative monetisation to push for a ban on the methods its competitor's use. Unintended side effects and regulatory capture are very real.

So....I dunno. Some people are doing bad things, but I struggle to define it. We probably all have run across a mobile game doing pretty shady things, but does that mean all loot boxes should be banned? And would this law really help, on balance?

[1]: Yes, I know Kinder Surprise eggs are banned in the US due to them being, allegedly, choking hazards. I don't think they should be, but at any rate, they shouldn't be banned because they contain a random toy.

Powerlifting is definitely not the same as general CrossFit and is pretty obviously a dangerous sport. I would guess that based on the amount of jerking and twisting I see in CrossFitters doing powerlifting that the injury rate would be higher still within that specific discipline. Again, all speculation on my part.

I’m thinking an intense workout with good form and control vs. a standard CrossFit workout.
My own little soapbox is that if you buy a product, it should always be possible for the consumer to return it to exactly the state it was at the time of purchase.

So no forced or unrevokable updates that ruin (or even change) things.

I have a TV that has on multiple times broken things with firmware updates, and there is no known way to downgrade. I'd name and shame the company but I'm sure that almost every manufacturer gets away with the same bullshit. Same with cellphone manufacturers.

From reading the article, I think they mean “determined” in the sense of controlled. They changed the potential distribution in the electrodes, and the single-electron wavefunction changed in a controlled way. The “geometry” is presumably the spatial probability distribution, including the spin.
Did CrossFit for 5 years and a shoulder surgery. During that time I visited about 30 gyms all over the US. At no point did I ever see rhabdo treated as anything but a serious concern. There was a gym somewhere that did that Uncle Rhabdo stuff but it’s inaccurate to act as though that is or was the prevailing attitude in CrossFit.

I have several issues with CF but this idea that rhabdo is glorified is not true.

We can only hope that US voters will end up electing a government with a functioning moral compass in the near future. Perhaps said government could end up pardoning the whistleblowers exposing the crimes of the previous governments.

You could spend all day arguing whether Assange is a journalist/publisher, or whether he's still just Mendax getting his rocks off. You could argue about Manning and Snowden's methods. You could argue about every other whistleblower's way of coming forward. But you can't deny that each of these people exposed serious crimes perpetrated by the US government. Spying on citizens, torture, war crimes, etc.
I don't want to be this person - but who gives a hoot whether Everest is dirty or not? It is probably in the 1% of the hardest places to get to on Earth list, and the only people that go are the rich or sherpas who are employed by the rich. I think China/Nepal should make sure some of that $50k+ permit fee is going towards cleanup for long term profit maximization, but I don't see why any otherwise normal person should care about it.
Starlink – SpaceX’s broadband internet system
We are very far away.

We are several theoretical and engineering breakthroughs away from a scalable quantum computer with sufficiently many error-corrected, logical qubits to do something useful with Shor's algorithm. The current rate of error-correction needs to decrease by a factor of 10 - 100. The current state of the art in physical qubits needs to increase by a factor of at least 10,000.

If we assume the number of usable physical qubits doubles every year while the decoherence rate halves every year, it's plausible a quantum computer could be designed to break 2048-bit RSA in slightly under 20 years.[1] To be generous, we'll also assume the implementation and engineering work doesn't meaningfully increase that estimate once the design is finished.

This is an optimistic forecast, to put it mildly. There are credible arguments from skeptics[2][3] in the academic community that it's not actually possible to build a quantum computer capable of breaking RSA in practice. Likewise, everything I've mentioned is only in regard to the known unknowns we need to resolve. It's very probable there are a variety of unknown unknowns to contend with as well.

This is also all aside from the possibility (emphasized by the first report I cited) of a looming winter in quantum computing research. In order to actually reach a point where RSA can be broken, the field needs to start paying out the checks it's been writing. This means actually achieving quantum supremacy and developing legitimately useful quantum computers - scalable or otherwise - for industry applications.

Finally, D-Wave's progress isn't relevant here. They're building a quantum annealer, not a general-purpose quantum computer. All the foregoing is based on the idea of building a general-purpose quantum computer to implement Shor's algorithm. Annealing methods aren't applicable.

Here's a good blog with a breakdown of costs to climb Everest and how they're evolving: http://www.alanarnette.com/blog/2018/12/17/how-much-does-it-...

Sounds like 2019 is the year of China exerting full control over the Tibet-side approach:

"In my mind climbing in Tibet has just become more expensive and more controlled. While the intent of some of this is good (trash, centralized rescue) others are onerous in nature and can result in unexpected expenses. Climbing Everest from the North or Tibet side was historically seen as cheaper, wilder, freer and more independent than the Nepal side. Well, that ship has sailed. If you want a more independent 8,000-meter climb, Everest is no longer on the table. Take a look at Makalu or Dhaulagiri."

> I'll take the imperfect security of forcing various agencies to expend resources to go after me personally (which is a small chance of happening) versus the ease of them simply vacuuming up all the bits.

On the one hand: protection against passive monitoring is a clear win. On the other hand, in my opinion, saying something like: "which is a small chance of happening" is kinda problematic: you don't need that security, and if some agency targeted you, like, maybe there is a minor chance of personal embarrassment. However, there are also people in the world that when they are targeted, they could face prison time or worse. And the people with the most to lose, are also the most likely to be targeted. So, IMO, it would be somewhat irresponsible to rely on tcpcrypt - it gives people that don't really need protection protection that they don't need, but leaves everyone that does out to dry.

The thing is - I just can't think of a use case where it makes sense. HTTP is often used with TLS - and TLS offers protection against active attackers. Many new protocols are based on HTTP - right or wrong, that generally means they get TLS with whatever library they use. DNS is moving toward DoT and DoH. SMTP has STARTTLS already which does the same thing. FTP has been replaced by SFTP / SCP. Telnet is replaced by SSH. Instant messaging protocols have built in security.

What protocol and who would actually benefit from this?
You are assuming that everybody in this system is honest: researchers, funders, and companies. None of these entities need to be honest to do research or to come up with topics. This is a big fallacy with academic research: nobody needs to be honest or truthful, and as much as you like to believe they are, they have no reason to be honest. I have experienced this first hand during my PhD life.

> Researchers are normally happy to do important things and they have good ideas.

That's not how research works, however---at least not what I experienced. Usually a goal is the prerequisite of the funding. If that goal doesn't align up with the interest of the company/or the funder, there won't be any funding to begin with. That's a lie that researchers tell themselves, that they have the freedom to work on w/e they find amusing.

> Academia being driven by money has less to do with academia and more with lack of money it needs to work on independent research.

Sure. If academia was a utopia that wasn't so dependent on money (and fame), science would take over. That utopia isn't anywhere in sight, however. Try going through academic job market: a popular question you get is how you are going to bring money into the university. If you don't have a good answer, you won't get a position. As a professor, you will be spending 80%+ of your time writing grants or, as you put it, begging different companies for money. The other 20% is spent on classes and bureaucratic headaches. A good professor that I knew had a long rant on how she never gets to do research anymore (from a very well known university).

People twist words and data to make their point, get a publication, make a name for themselves, get more money, and repeat the cycle, all in the name of research and science.

My point isn't that the academic people as a whole are bad, but many of them are trying to survive and are willing to do w/e it takes to bring in money. It is very easy to abuse the bunch when people are trying to survive.

All I am suggesting is that you need to be critical when reading academic papers. Regardless of the content, topic, etc. read and decide for yourself---if it is a field that you are proficient in---or read opinions on counter points.

> Now you aren't even supposed to do `new`, but rather std::shared_ptr<...> or std::unique_ptr<...> (as appropriate).

Apples and oranges. Smart pointers are wrappers over raw pointers. They extend functionality, but are not the same.

> Except that you generally create them with std::make_shared() and std::make_unique()

Again, apples and oranges. You're confusing factory functions that wrap memory allocation for convenience with actual memory allocation.

At most you could only complain that those factory methods duplicate the role of constructors, which would be silly.

> And then you have the fun of passing those to a function. Do you pass by value (shared_ptr) or by reference (I believe you do not) or pass a naked pointer (when you need to pass a unique_ptr to a function that uses, but does not modify or cache the pointer, if I remember correctly).

There is no duplication in your examples. You are just unaware of how those functionalities are used.

The thing is, you still need to validate the session id, if you want to know who you are talking to. And in order to do that, you probably need to do something like use x509 certs. And once you do that, you've basically re-arrived at the same layering issues that TLS has.

So, like, the protection against passive listeners is nice. But, what I don't understand is a specific example of where using tcpcrypt would be better than just using a widely used TLS library.
