Expert Explains Negotiating with Cybercriminals
I don't know a single person who holds their money in 'cash'. They invest it in the market, real-estate, business development, etc.
Do the Matrix clients still phone-home to some centralized server (Vector, I think it's called) as well as to matrix.org on every launch?

That's what kept me from switching last time; to me a federation client that's going to phone home to a central server is no better from a privacy standpoint than using Signal (which isn't federated but is also end to end encrypted and phones home to its centralized server), and Signal's UX is better thus far.

If that can get solved (and it seems like it can), Matrix looks like it's going to be super awesome.
> Apologists will point to most crypto-mining using renewable energy. Yes, because hydro is the cheapest power. But all the hydro power use can actually limit the power and/or make it more expensive for everyone else.

As an admitted apologist, that's one of the weaker arguments. The most compelling to me is that power usage isn't properly compared to traditional banking. Sustaining all of the people and in person infrastructure required for traditional financial transactions requires more than just calculating the cost of transmitting the transaction. In fact those parts are comparatively cheap, it's the verification that's expensive, in both systems. All of the people employed in banks who play any kind of role have an enormous amount of cost associated with their employment. I'd like to see a comparison of heating and cooling costs for all of the banks in the world, which is just a small slice of the total cost of traditional banking, factored in to comparisons. The only one I've seen compared it to the computing cost for processing VISA transactions, which didn't seem like a proper comparison.

I'm also generally suspicious of some people (not everyone) who's gut instinct to environmental impact are limiting the spread of innovative and extremely useful ideas rather than looking at how to decrease the impact, particularly when those ideas help to decrease reliance on powerful central authorities. Proof of work is the innovation that allowed cryptocurrencies to scale to the level they are today, and it's precisely that work that allows them to operate securely despite being decentralized. Abandoning it because of the impact rather than reducing the impact would be like abandoning cars rather than making them electric and more efficient.

The issue is that production is inelastic compared to demand, so scalping provides no additional value and creates higher prices by making demand seem even higher.

On the topic of spreadsheets:

Rich Harris has it right. LANPAR is in fact the world's first electronic spreadsheet. The inventors/creators also invented implementing Forward Referencing - the cornerstone of spreadsheets. This was in 1969, ten years before Visicac and 14 years before Lotus 1-2-3.
LANPAR was used extensively for Plant Budgeting operations across every telephone company in North America throughout the early 70's.

VisiCalc, SuperCalc and TKSolver did not have Forward referencing. You had to manually refresh the screen (recalculate the entire spreadsheet) and watch to see when cells stopped changing values (if they needed results from cells further in the spreadsheet (left to right, top to bottom).

Lotus 1-2-3 did have Forward Referencing. Multiplan I, did not and accordingly could not hurt Lotus until MultiPlan II incorporated it.

I had communications from magazine editor(s) who simply had not been aware of LANPAR because it was so far ahead of its time, and 10 years later VisiCalc implemented its spreadsheet on Apple's microcomputer - popularizing spreadsheets at a consumer level. So Yes, Rich Harris got it totally 100% right!!

> De-rated units are usually chips that didn't perform as well as they could have

"usually" is not correct here. They are sometimes chips that didn't perform as well, but usually they are actually higher-tier chips that are artificially locked down to perform at lower levels.

AMD had over 80% of their Zen1 chips and over 70% of their Zen2 chiplets coming off the line with 8 fully functional cores. Yet they probably have 60% of their demand being 6-core or 12-core parts (2x 6-core chiplets). What do they do? Lock off 2 cores and sell 8-core parts as 6-core parts and 12-core parts.

It is nice that they have something to do with the chips that actually are broken, but most of them are just gimped for price discrimination and market segmentation.

https://wccftech.com/amd-zen-yields-80-all-8-cores-functiona...

https://www.guru3d.com/news-story/amd-zen-2-production-yield...

Same for the Phenom II X3 - almost all of those really had 4 functional cores and you could usually turn them back on. Why were they being sold as 3-cores? Price discrimination and market segmentation.

Or for a more recent example - the rumors of an impending 3080 Ti launch in January turned out to be true! Someone got a picture of the actual chips, with a big line through the 3080 Ti part number, re-marked with the part number for a 3090. NVIDIA decided to cancel the 3080 Ti launch, and sell the parts as 3090 - and those parts were actually 3090 tier parts that were being marked down and sold as 3080 Tis.

https://videocardz.com/newz/nvidia-quietly-remarking-geforce...

It is a reality in this industry that you are constantly being sold artificially gimped parts, because price discrimination is the financially optimal strategy. It's better to charge a price-insensitive customer way more, and to still have high-volume parts for price-sensitive customers, than to have insufficient inventory to supply price-sensitive customers, or to price everything "fairly" and lose the price-sensitive customers due to prices being too high. But due to the way yields and binning work (you don't want to have high-volume SKUs that are difficult to produce - you want high yields even in your top SKUs) you have the most parts available in the bins that have the lowest volume, and the lowest amount of (broken) parts available in the lower bins that you sell the most of.

Screen time in general is correlated with depression ( https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5574844/ ), so it shouldn't be surprising that specific screen time activities are correlated with depression.

It's popular to demonize Facebook, but the reality is that sedentary activities in general are highly correlated with depressive symptoms. This goes both ways: Being sedentary instead of active is unhealthy and can exacerbate depression, and being depressed can exacerbate sedentary behavior.

Facebook is just one example of a sedentary activity, but watching TV and using a computer for leisure are also highly correlated with depression.

It's entirely possible that Facebook has some unique properties that make it worse than other sedentary time-wasting activities, but we need to be honest that it might simply be equivalent to other sedentary screen time activities in this regard. Without actual data, we're just guessing and projecting our feelings about Facebook onto correlation studies.
Agreed. Unfortunately I don't see that going away. Politicians don't write bills - lobbyists do.
I was going to say this myself and it's the exact reason I left all social media platforms. So many times I came away feeling bad about myself, I can do that plenty on my own, I don't need digital help.
> Such a vanishingly small percentage of cryptocurrency activity is actually used for trade (as opposed to speculation) that it is a novelty and newsworthy when it actually happens.

First, that last part is definitely not true. People do accept Bitcoin and buy things with it, and it’s not newsworthy at all unless it’s a meme-driven electric car company boss doing it. But secondly, why do these percentages actually matter? At what point does my valid use of something become dismissible because another use case which you don’t like gets popular? Do we dismiss people who actually like playing the Pokémon card game because lots of people collect the cards purely for speculation now?
Well, I wouldn't consider working for ad-based businesses and don't rely on advertising in business models for my startups.

Some extremists will always try to push for the state of moral indifference (i.e. things are benelovent or evil, only two options)

We are seeing this everywhere already. Examples:

- Voting for republicans means you are killing gay people. Some will go as far as 'no vote' means you kill gay people.

- Working at Facebook means you killed Rohingya.

There is another option: nobody cares _really_ because working at Facebook is in no way as evil as working for the companies that you mentioned.

If we followed the same logic, then TV would be evil. It's addictive and sure cause depression. Hell, Hacker news makes me miserable sometimes with all these Show HN posts...
I don't think that's right. The UN is sanctioning X could be approval or disapproval.

Maybe they're sanctioning vaccine sharing. Maybe they're sanctioning nuclear weapons testing.

Now if we say 'applying sanctions' it definitely means disapproval.
That's fine in isolation, but mixing that inside a comma-separated list is not a good idea.

I used to port Unix to 68ks - there were several ways to get around this issue - 68010s could happily take a page fault, or you could use the (tacky and expensive) two 68k thing (few did, it was a real pain).

For a traditional swapping kernel (ie anything prior to SVr2) the only time you ever needed to be able to recover from a page fault was when you did automatic stack extension, there was a simple solution to this, have the compiler emit a "tst n(sp)", or similar instruction at every subroutine entry - because it was an instruction without side effects the kernel could recognise it, extend the stack space (by enough extra to be able to do the next call, hence the 'n') and resume execution by faking the appropriate kernel stack frame

Doesn't this assume you only get liquidated below your initial purchase price?

With something as volatile as cryptocurrency it's not exactly a crazy idea that you'd buy at say $30k, take a loan at $60k and get liquidated at $50k and get stuck with a big tax bill
I guess I feel like someone who did 8 years of school and I believe 4 years of residency which altogether generally costs them over $100k should be compensated for those expenditures of time and money. I don't feel that an aspirin should cost $5 just because you're laying in a hospital bed.

Maybe it's the opacity surrounding billing. What exactly costs $7k when you are hospitalized for 3 days? Hell, let's skip the ER and the procedures and go with a mental health inpatient stay. There's 72 hours of oversight by the staff. If they're making $20/hour, which isn't off-base to my knowledge and may be generous as they generally aren't BSNs, that's $1440 in wages. Food for 3 days and maybe an hour, hour and a half of the doctor's time over the course of 3 days, and medication. Those additional things don't add up to the remaining $5,560. Even with the cost of the building, electricity, janitors, it doesn't add up. So why does it cost so much for a 3 day stay without an emergency medical procedure?
To build an open source decentralised Discord alternative you need a tool-box of primitives - that’s what Matrix is. Then clients like Element (https://element.io) sit on top to fill in the rest.

We don’t think the model for Spaces is overcomplicated. In fact it’s simpler than Discord (no role-based permissions; just power levels).
It appears that screen time in general is linked to depression, with or without Facebook. Example study: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5574844/

Binging TV shows, binging Facebook, and binging internet usage in general are all highly correlated with depression.

With correlation, it's important to remember that causation doesn't necessarily flow in only one direction. It's likely that depression causes increased sedentary activity, including Facebook usage. It's also entirely possible that social media usage encourages depression by displacing more productive, healthier activities.
They are not economic parasites. They are the physical manifestation of the Invisible Hand. These are people doing God's work making an efficient market. If you don't want arbitrageurs to capture that value, maybe NVidia should start pricing their products correctly so that they capture the value. This isn't rocket science.

> If this has any effect on anybody who isn’t a crypto miner, it’s going to be to open up possibilities and/or save them money. I have trouble finding fault with that, and we’re surrounded by far more egregious erosions of our “right” to buy and use general-purpose computers.

This is a wildly short-sighted take.

Because I have nothing to hide and if this has an effect on anybody besides them it's just going to be to make their skills more valuable.

Then they came for the debuggers--
But I still didn't speak out, because we're already surrounded by egregious erosions of our right to buy and use general-purpose computers, so what's the point, amirite?

Pretty exciting stuff, still trying to wrap my head around some of the technical possibilities outside of chat. Just to be clear, a room can be contained in multiple spaces, right? Or even, if I'm understanding it correctly, in multiple places in a hierarchy in the same space?

The Element blog post talks about setting up admin spaces and community spaces. So if rooms aren't exclusive to a single space I could build custom, private spaces that pull rooms from multiple different communities I'm a part of.

That's a really cool feature that Discord doesn't have right now.
it's ridiculously unfun playing multiplayer against folks who have exceedingly fancy exotic gear I had no time or patience to grind for. I say had because I couldn't go grind out that gear anymore if I wanted to, if I had the hundreds or thousands of hours. gear is a apart of seasons, so you are either there, grinding for it, or you are forever without.

for a brief moment Bungie was going to at least phase out some of the old amazing war trove folks had built but "popular" outcry & a wave of un-nuanced brutal bad press ruined that.

the game sucks. you can't have both an MMO grind aspect and a competitive fps pvp. unless you only care about an ever smaller ever more selective community of die hards who ways have played your game and always will, at a copious rate, and you are willing to sacrifice the fun of every other person who plays your game.

First the operating definition of white supremacy, so we're on the same page:

> White supremacy culture is the idea (ideology) that White people and the ideas, thoughts, beliefs, and actions of white people are superior to People of Color and their ideas, thoughts, beliefs, and actions.

And from Jones and Okun (2001) we have a cluster of traits which are identified with white supremacy:

- perfectionism

- sense of urgency

- defensiveness

- quantity over quality

- worship of the written word

- paternalism

- either or thinking

- power hoarding

- fear of open conflict

- individualism

- only one right way

- progress is bigger, more

- objectivity

- right to comfort
Really cool experiment!

I wish they had included a detailed costs breakdown, as it seems like it might cost too much to be viable.

> Satoshi fixed a bug (that reverted it back to the initial rules everyone agreed upon).

The Bitcoin chain fork where the bug manifested wasn't reverted. Instead, a chain fork where the bug didn't manifest outgrew the one that did, and is now the canonical fork. If they wanted, miners could continue to mine the fork where the bug manifested. The point is, the Bitcoin protocol didn't change at all -- it merely presented miners and users a choice between two conflicting histories. You can start up a miner on the other fork today if you wanted.

This is not true for Ethereum. Because the undecidability of the EVM precludes miners from determining whether or not a given transaction would touch the DAO contract without first executing the transaction for less than the cost of executing them, there was really no good answer to dealing with the DAO hack. The options were:

* Let the DAO hacker keep the proceeds (this became Ethereum Classic)

* Change the network protocol to prevent the DAO code from ever running (this is Ethereum today)

* Change the EVM so it would permit miners to determine which contract(s) are reachable from a given transaction, thereby allowing them to filter out contracts that could move the DAO funds (a path not taken, because censorship)

The reason is they don't want private individuals entering danger zones just to make a buck - a profiteer could easily end up a victim from the dangerous situation.

> No, I think this is the first time a GPU has been heuristically trying to detect what you're doing and self-limiting in response

nah, remember when NVIDIA decided that Titans were now prosumer cards and would get Quadro series drivers, and then performance tripled in CAD applications once the limiters were removed?

https://wccftech.com/nvidia-titan-xp-titan-x-385-12-driver-u...

The distinction between a Quadro and a GeForce has literally always been drivers and firmware. NVIDIA would have the card look at the specific API calls being made and if it decided you were a CAD application then it'd slow itself down on GeForce cards, while running normally on Quadro.

AMD does the same thing with Radeon Pro, and Frontier Edition cards, and so on.
