That’s a very bad thesis to trade options on. The author believes that BTC is overvalued, but if you look at their reasons for believing it’s overvalued, some of them could have applied to BTC at any point in time over the past several years, and the rest could have applied to BTC and any point in time since it’s creation.

By buying puts on bitcoin (derivatives), they’re not only betting that they’re correct, but also that something will happen in the next 5-6 months that will catalyze the market to correct that valuation. They don’t have any thesis at all for what’s going to catalyze this correction over the next 5-6 months. Their entire investment thesis is that “[they’d] be astonished if we get through 2021 without an explosion”. The investment described in this blog post is just a crypto-bear yolo play, with less thought put into it than your average r/WSB post.

Edit: looking at the options chain for the BTC ETF they’re shorting, NTM puts are trading at $2, so the underlying has to lose about 1/3rd of its value for that trade to break even. If it goes to $0, their maximum profit is ~$400 per ~$200 contract. That’s certainly not a cheap contract.

Lol really i can internally move all the money around i will for free, this must be an american problem ?
I encourage you to read the current research on the medicinal uses of psychedelics and cannabis to see how these substances can actually help people.

People can actually overcome all sorts of mental and physical problems using these substances, and if that's not a net win for society, I don't know what is... especially considering the abominably ineffective mental health system and insanely expensive medical system.

Religious, sacred, and sacramental use of these substances is something many people also value, as is just having fun or connecting to others in loving ways (as with MDMA).

Not everything's about being a worker drone in the system and valuing your life and everything you do by how much you can contribute vs how much you cost.

It seems suspicious that this would be hiding in the eyes. A separate specialized organ would be more like the other senses.
So many things wrong with this article. Taking a bet against bitcoin it totally legit but please don’t over simplify things or make false claims.

“No real world use” for bitcoin and other crypto currencies: ok so the goods I bought for years with bitcoin do not exist? And the trading market you are playing on are not a real world use case?

“ These practices have run rampant on every financial market in human history that hasn’t regulated against them fiercely. Why should Bitcoin be any different?”. That’s the ultimate authoritative argument. “Everybody knows”, “obviously”, etc. Please back up with facts and don’t make general claims like that.

USDT: totally agree. But then don’t trade with usdt. Bitcoin not easily convertible to cash ? Maybe you should pickup a more serious trading desk. On boarding is much more restrictive than mainstream platforms like binance but nothing is more untrue that bitcoin is not liquid. You can settle trades in USD (not USDT) instantly with a serious regulated broker.

Limitations of bitcoin: mining, fees, other. Agree, but nothing of these problems makes bitcoin an insider scam. Is there is a problem there is a solution. Who says that these shortcomings can’t be solved ?
They bought puts so their short position can't blow up, they have a fixed maximum loss (that they've already paid)
What to do with crowd-sourced computing power?
If you had access to an entire network of household PCs, where would you apply all that computing power?

Some context. I built a platform that accelerates CGI processing / rendering for design professionals (architects, animators, interior designers, etc.) by using a network of average household PCs. The product works, and renders for Blender & Vray for SketchUp pretty fast across 50 PCs.

But the margins are terrible. PC suppliers get paid for work completed on their PC, which needs to be enough to make it worth their while (electricity cost, giving up PC usage) but the 3D renderfarm industry is near perfect competition with all its margins competed away, not to mention the licensing costs for distributing the 3D software across all these PCs. There are PC suppliers beating a path to my platform to supply (mostly from Asia) to earn a profit with their PCs, but I'm struggling to solve the demand side of this equation.

So now I'm considering to pivot/change the idea and re-apply all that computing power elsewhere, like supercomputing-as-a-service of sorts but I have no idea where to look and where to begin.

My sanity's going out the window and I have nobody else to talk to about this, so here I am.
Kubernetes is like sex in high school. Everyone says they’ve done it but very few have actually done it.

It’s a bit early to say anything. If anything the death of k8s will be sparked by all those who fail to implement it the right way like we all did with AWS.

I first got into AWS very early on and one of its early official selling points was ephemerality yet most of us treat everything as pets, EC2 has affectively become just a vanilla hosting/managed provider with an API on top.

K8s isn’t difficult or complex, it’s just different and once you get it you get it. What ruins it is things like not following its intended paradigm, breaking the isomorphism and determinism of the containers… insisting things ansible, chef, salt, et la.. are still required. Grabbing a shell into container to debug something non app related, effectively breaking the ephemeral nature. The only thing you’ve effectively done is added additional complexity without hacking off any of the stuff that should be dead

Before k8s goes out I think no-code and then by extension no-infra will become a lot more ubiquitous, and if anything no-code will consolidate off a good chunk of our industry
The highest death rate both in the US and Europe was this past winter, long after the virus had already spread to every part of both continents.
Tesla cars catch far less fire than their competitots's, EV or ICE. This has been debunked years ago, check your sources.

As for credits making their profits, first it's like saying early Anazon could never turn profitable and second, just wait for the P/L report of this 2020Q2. You're in for a big surprise (my bet: profitable without counting credits amd even S/X sales!)
The threat model of proof-of-stake (PoS) is weaker than that of proof-of-work (PoW). For example, "initial sync" (a new node joining the network, needing to find the sequence of blocks that everyone agrees is the right sequence of blocks) is much simpler with PoW compared to PoS. And, furthermore, with PoS it's possible to compromise this process by stealing private keys from a group that comprises a majority. An attacker can do this silently, and at some later date start publishing alternative chains, thus breaking initial sync by offering multiple, valid chains to new nodes, thus making them unable to decide.

In contrast, it's not possible to steal a majority of PoW mining power, and sit on it for an extended period, without (a) foregoing a large profit, and (b) risking that others acquire more mining power than you have.

One of the Cardano whitepapers [1] contains a good summary of the advantages of PoW over PoS in Section 5.1.1 under "Consequences of PoS vs PoW":

A crucial difference exists between PoS and PoW at the network layer, with significant design consequences: in PoW-based systems, proof-of-work itself gives honest nodes an advantage over adversarial nodes (as listed below), and this enables system designs that are simpler and more modular. There is no such advantage for honest nodes in PoS-based systems such as Ouroboros.

In PoW systems:

• The number of different block headers with a valid PoW that can be constructed (over any given period of time) is bounded by the total available hashing power in the world. In Bitcoin for example this is one header every ten minutes on average.

• The header PoW can be checked with little computational cost. This does not require any significant or recent state, only a vaguely-recent lower bound on the hashing difficulty value is needed.

• Such a cheap and simple test can be easily integrated into existing distributed algorithms such as broadcast algorithms.

By contrast, with PoS in Ouroboros:

• There is no equivalent of the PoW check that is expensive for the adversaries and cheap for the honest nodes: adversaries can create many apparently valid or actually valid candidate headers or whole chains.

• Block headers can only be fully validated with access to a very recent copy of the full ledger state, and the other preceding headers – which is not a simple stateless check.

• Having the full ledger state relies on the other two pieces of Ouroboros functionality: chain validation and chain selection

At what point a 'name' becomes an 'infodump'? :-D

Or more aptly, what constitutes a single molecule, rather than a complex structure built from a repetitive pattern of almost-equal components?
Other chains are figuring this out now and i havrnt heard of any majot hacks so seems to work out
Shouldn’t the JVM already be doing this, as part of dead code analysis during the compile step? I believe tree shaking in JavaScript also only handles static analysis — eg imports and function calls.

I imagine though usage of something like exec throws DCE right out the window, poisoning the whole program
It seems like you've got a lot of people expressing a similar experience. You're not alone!

But I have to say no, never in my life have I ever experienced something like that. So it's not a human universal.
Internal token money is a great way to mess up incentives in my experience. The most obvious offender is IT that charge silly money for computers. Utilities per head is a fixed cost even though the amount of office area, toilets or Ethernet jacks also are fixed. Etc.

Resources that are underutilized are not borrowed by other departments since they have to pay for it even though the marginal cost of usage is almost zero, so they buy their own or don't bother.

The end game is that the internal fairy tail costs will be used as a excuse to outsource stuff and pay real money to expensive external suppliers to save the pretend money in the department budgets ...
"Markets can remain irrational longer than you can remain solvent." - John Maynard Keynes

Speculating on options based only on irrational pricing is a risky game. You could be waiting years for the correction to occur and it might never occur if the fundamentals change to make the price more rational.

You can increase your safety level with a known catalyst. In this case, it might be something like an SEC investigation into tether, but you'd have to decide on the timing, the probability that occurs, and how much it could ultimately decrease the related stock prices.

Personally I think the kind of work I do rewards learning things/executing things fast. I take extended periods of doing the same things as a.. bonus? Things will always change, and in FE development I feel like it's all integration. Which is fine for me, and what I want to sharpen is to be quick and have a feel of what kind of integration does the business/story/ticket needs. Balancing that with maintainability and teamwork is what's interesting. The programming part is only a tool for me. I'm happy that I get paid to solve problems mainly with my programming/abstract thinking skills instead of managing skills or negotiation skills; not programming itself.
I never remember my dreams, and I suspect I'm aphantasic. As far as I'm concerned, 99.something% of my sleep follows the pattern of fall asleep -> void outside of time -> wake up.

There are extremely rare fleeting moments where I might wake up and remember some details about a dream for a few seconds, but then I lose it. Those would be counted on one hand per year, easily.
The issue is that docker circumvents a platform security control without warning.

Docker on Ubuntu has a critical security vulnerability, with a track record of being exploited. That, clearly, is something that should be fixed ASAP.

If you have just a single layer, sure, blame yourself for poor security practices. Services should listen to unix domain sockets or internal networks only. They should have authentication in place. Machines should not have routable IP addresses. Machines should have externally applied firewalls. And so on. That doesn't mean the security layer that did fail shouldn't be fixed.
It doesn't have to be perfect, from static analsis you can get what people want. It won't cover dynamically created keys but people don't use it anyway. You'd just have to provide list of entrypoints and ie. vscode plugin could gray out or put horizontal grey bar for code that's shaken. It would be great plugin.
"n" is the number of bits (what you referred to as "X").

Storing one value into a tree is O(log(X)). However, storing all possible values for X bits is 2^X operations, each of which requires log(X) sub-operations to store it.

Pre-calculating all possible input-output mappings requires looking at every possible input value. Thats 2^X.

That isn't what P =? NP is looking for. The forward function, A, isn't a big look-up table. Instead, it's a much smaller set of transformational steps. So if A(y) is defined as y+1, you can code it with about X primitive logical operations. One operation could be "output[least significant bit] = xor(input[least significant bit], 1)". That operation causes a transformation to every single input value, and is thus very powerful and economical. Other operations would ripple the carry to the more significant bits; the next-to-least-significant operation transforms half of the input values, the next bit affects one quarter of them, and so on.

P =? NP asks if it's always possible to come up with a reasonably small set of transformations that go the opposite way. You can't do that with a process that looks at the discrete values. If it's possible it will require some kind of comprehension of the algorithm's structure. We can't (in polynomial time) create an inverse of "y+1" by listing what happens for each possible input value. We need to recognize that the inverse function is "result - 1" and provide the primitive operations for that.

I find hard to believe that you can decompile any app that has bothered implementing key pinning (which I always assumed is done at app level, not OS).
The amount of people who don't care even on this site vastly outnumber those who do. And this is the cream of the crop compared to any other community in security/digital awareness.

Thinking about this ratio among the average population makes me think the worst is yet to come.
Depends on the bug, if it hurts the business it's generally fixed instantly, if it's just an annoyance, feet are dragged.
Holy shit, I've been running open ports for a year with docker, completely ignoring my firewall!
This has to be fixed ASAP.

yeah. the black caucus. are you for real?
It's funny how the rest of the World is suddenly expected to adhere to U.S. cultural boundaries even though they simply don't apply. All of a sudden I've somehow changed ethnicity to "White". Simultaneously, people of African, Middle-Eastern and Indian origin -- some of the most ethnically diverse areas on the entire planet -- are just considered "Black" and thought of as a single group.

It's outright ridiculous.
Oh I can rephrase it if need be.

Rephrased Question:
What was the last year in recorded history that the global average temperature was lower than average?

As a second question,

Define x = “normal” || “average”

If you are questioning what “x” or “x temperature” is as an axiom, then what is your definition of “x”?

I don’t want to talk past you if you have a different definition.
If you have a different definition than I do however, I need to understand what that definition is before we have any sort of discussion.

No, no, no. Cryptocurrency fans keep making that up.
In fractional reserve banking, the bank uses deposits to make loans. The loans have collateral behind them, often real estate. There are real assets backing the loans.

That's not how Tether works.

Tether is supposedly invested in "commercial paper", but that has to be fake. If they were really buying commercial paper, they'd be in the top 10 commercial paper buyers. The trading desks that trade short term commercial paper would see billions of dollars of transactions from Tether. Traders report they're not seeing that.

The arguments outlined are not particularly strong unless you are already predisposed to not liking Bitcoin (which is fine, not liking a particular security is a perfect reason not to invest in it - however it's a bad reason to bet against it)

1: BTC is not controlled by insiders. Sure it's a great headline but once you account for the fact that a BTC wallet owned by an exchange that pools large amount of customer funds is not the same as Alice's Ledger nano you will quickly realize that assets are actually reasonably disbursed across many parties. Eg: https://insights.glassnode.com/bitcoin-supply-distribution/

2: BTC by design will take around 10 minutes to confirm a transaction, further you will actually want 3-6 transactions to be really confident in finality. I agree, I am not waiting inline at the grocery for 60 minutes either. However dismissing layer 2 solution like lightening network deserves something better than handwaving. Lightening network works very well in my experience. Also I need to wait 5 days to transfer cash from my broker to my credit union, I wish I could use BTC. Finally wire fees are a trash fire.

3: Tether. Trading tether (or USDC or DAI) into fiat is quick and easy. Converting USDC to dollars is also easy. Yes tether is 'kinda suss' in a bank run scenario. USDC however is audited and regulated. I've seen papers both indicating that loose tether issuance distorts BTC prices and papers that cannot find a correlation. So this feels like a tossup (personally I hope all the fines and scrutiny on tether forces some house cleaning but I am not holding my breath)

4: lack of regulation. Regulation is not a cure all, Madoff pulled the wool over auditors eyes for years, no one was prepared for LTCM, regulators couldn't stop the 08 financial meltdown, and so on. BTC has no native ability for centralized control, however it also has 100% transaction transparency. That it extremely valuable. Finally centralized exchanges need to comply with local rules and regulations (have you seen the travel rule? That's some forceful regulation there).

5: is actually a repeat of 1 and 3. The insiders argument is overblown and turning stablecoin into fiat doesn't require 'good luck'. ( I am a very unlucky person but have done this multiple times myself).

6: PoW is ecologically unfriendly. Yes BTC energy usages should give pause. However it is only fair to talk about them in the context of the ecological effects of fiat money. Fiat printing is the way we have financed the last 20 years of war (whatever happened to war bonds??). If BTC underpinned our currency system there'd be a lot less room for environmentally destructive jingoism.

7: Libertarians are dumb so they must be wrong. Nothing to say here but ad hominem arguments don't seem effect asset prices.

I struggle to find arguments here that would give me conviction to say BTC will crash in 6 months. I am 99.9% convinced that Tim Bray doesn't like BTC as a financial instrument but that has no meaningful impact on BTCs price... (It is not like he's Elon Musk ;) - actually I think Elon's market moving mojo is all gone now)
I know that Microsoft is doing some kind of treeshaking in Blazor (basically a .NET runtime in WASM), since they do not want to ship a full .NET base library to the browser. Not JS related, but the problem is the same - you want to ship as little data as needed on websites that are dynamically loaded.
Just add all the sizes, and account for padding (there isn’t any here because everything other than the flags field is bytes arrays)
I was initially annoyed by this, and then thankful. I have learned never to install apps of this kind, and thus the fact that Reddit has made itself unpleasant to use from a browser is a helpful little nudge away from a time-waster.
This proposes to add expanding accordions to the navbar and to some pages. Will these work without JavaScript?
That makes no sense? There isn’t any padding, and if the bytes are not 8 bits it’ll never work anyway.
Python's single dispatch just means that if I do `foo.bar()`, the meaning of bar depends on the type of `foo`. So that is not recent, but a core part of the language.

Another difference to Python is that you can't add new methods post-hoc to types in Python. That's a big problem, but this has nothing to do with single/multiple dispatch. E.g. Rust has single dispatch but allows post-hoc methods.
That is the hardest way. It is easier to regulate Facebook and make it behave correctly than to try to change the behavior of a thousand million people in hundreds of countries that want to be in contact with their friends and loved ones.
Does anybody else experience a similar phenomenon but with their auditory system? Whenever I'm falling asleep in a room with white noise (usually a fan) I swear I hear people talking, songs, animal noises... But it's just the fan.
Sure but that has no relevance whatsoever to the article do the objection is irrelevant.
I experience exactly the same thing, with me it happens when I am very tired. When I was younger (<10 yr) it made me really afraid. I can remember a new years eve that I was so tired and scared that I was literally terrified and hid in the corner of the room and my parents did not know what was happening to me.

Now I know what is happening and I just take it as a sign that I'm very tired. It's comforting to see someone else describing the same thing that is happening to me.

My "logic puzzle" is moving endless amounts of large, heavy cubes in holes that keep on appearing when I fill them. The visual aspect is only a part of it, the emotional feeling of the endless task is another.
