If they can simply change the key needed to sign the bios or whatever for new cards coming off their production line they can continue to support cards that were sold before the change and have the limiter for cards made after the change. They could also make a tiny to change to the model number. I don't see how they could possibly be sued for doing so.

Nvidia is making the same money regardless if a miner or gamer buys their existing cards. They won't be losing any money of 100% of their production goes to gamers. As a game er if this reduces miners interest in the products I want I'd say it's good for me.

I don't know about that. If the the typical HN reader cared about solving problems they wouldn't switch jobs every two years and keep rewriting the same things over and over in the latest fad framework.

Are there interesting technical challenges related to Bitcoin mining which induce competition and innovation? I ask because I see Bitcoin mining dismissed in the same way high frequency trading is (if you have enough starting capital/connections, you get to print money). However I know enough about HFT to realise that characterisation is very unfair (plenty of firms go bust, they capture a lot less value than the people they replaced, innovation is rife), is there anything similar going on with cryptocurrency mining, or are the surface level dismissals fair?
I remember years ago (we're talking 20 years), it was possible to circumvent chip level batching between Nvidia Geforce and Quadro.

Geforce was the consumer range, and Quadro was used for workstation graphics.

They both used the same chip .. but a resistor on the board gave the driver an indication of which range the card belonged to.
We get something useful from aluminium production.
Also, give fib(48) a try. Python will switch to bigint, but (https://github.com/gioblu/BIPLAN/blob/master/documentation/n...):

BIPLAN supports only one numeric variable type that is by default int32_t

So, fib(48) will overflow, and probably will return a negative number.

Preferring to give the right answer over giving an answer fast is one of the design decisions Python made.

There also is the unconventional choice to use a global array to store variables, leading to “BIPLAN supports a maximum amount of 116 global variables”. I don’t think changing that to make it growable will affect speed much, though.

For some people the choice is governed by the educational institution. Sure, I could have applied to UofT but my research led me to McGill (and I’m frankly glad that happened).
I’m not a fan. Kinda creepy.
I think it is probably good to tax for Co2 production as a way of addressing global warming. I just don't think we should equate bitcoin production with other CO2 producers. I.e. I personally think that the CPU-cycles used for science on HPCs are much more valuable than the bitcoin mining (that's just my opinion though).
Agreed. Their example is that selecting Elixir was a great choice for them. Cool. That was using an Innovation Token.

I'm guessing that in addition to Elixir, they also used plenty of boring technology. Like using `cron` or `at` rather than writing your own scheduling subsystem. Or building on top of a standard OSS database rather than rolling their own.

The point isn't to _never_ to use new technology, but rather to use enough boring tech that you still have mental bandwidth to pour into the new tech, innovation, or product that will be your competitive edge.
Agree, but I find that I spend more hours problem solving than creating. But that maybe says more about me than about anything else!

I hope so too, please don't let me stop you! :)
How long until gpgpu isn't cost effective for mining? I know a lot of fpgas went on ebay for cheap when the new xilinx line came out. The watt per hash has to be lower for fpgas already. Will the cost of a coin always reflect the current price to make a new one and thus gpgpu will always be a cost effective technique?
I like how you mention that upbringing gives a head start in these positions.

The majority of my bosses were incompetent as hell from a technical or project management perspective and I always wondered how they could be in these leadership positions. And I have a feeling it's knowing the culture of management and the terminology, communication style, and hierarchy enough to build trust with those leaders above them. I had a pretty rough childhood and have always struggled with fitting in with this managerial group and wonder if partly because of that upbringing.

Hilarious and brilliant tip, thank you!
> Kind of sickening, to be honest.

This kind of sorting could actually be a good thing if resources were adequately devoted toward helping problem students find better outcomes. I wonder, for example, if trades education would be better suited for many of the problem students—allowing of course that there are manifold causes for bad classroom behaviors and poor outcomes.

Education is difficult, and I've snipped a rather lengthy comment that would probably be a waste of time to read. In sum, I think differentiation with strong socio-economic support (i.e., a social respect for all lines work and economic support for them) is probably a better solution than dumping people into classrooms who obviously don't belong there (at least not right now). But this is obviously hard to do (or else we'd probably have done it already).
I agree, taxing carbon usage is the correct way to go about this. All the ways I can think of taxing Bitcoin directly wouldn't modify the right behaviors. It seems like the options would be:

* Tax Bitcoin transactions - decreasing Bitcoin transactions wouldn't decrease energy usage

* Tax Bitcoin holdings - this is already accomplished via capital gains taxes, and again, it isn't the holding or usage of Bitcoin that causes the energy usage. It's the fact that Bitcoin has value that causes usage.
Contrary to what some seem to think, for most people, getting a new well-paying job isn't a matter of sending a couple of emails and starting somewhere else for the same or more money the following Monday. I've been unhappy, for certain values of unhappy, for periods at probably every one of the handful of jobs I've had over the years. I've either worked through it or I've switched jobs. But it's never been something I've done casually.

That's true to a point, but... is that just being lazy? Aren't those all in "compressed" vector maps and could be rendered as needed with video hardware?

Don't get me started on icons. Icons, if anything, have gotten progressively worse somehow with more resolution and colors. It's almost like the reduced color palette caused more sudden color transitions and communicated the icon's purpose back in the day.

Which might have underpinned material design... but that entire movement, at least its major expressions (e.g. Windows 8/x) is an utter disaster.

In my state, they report the number of students who took the state test for each school as a percentage of population. I would be suspicious of any school that doesn't have over 98% take.

Yeah they can have a few kids not take it, but the overall score still is impacted by 98%.
Is BTC really more stupid way to burn resources than making sports cars? F1 racing? Gold mining?

There are tons of things the society could do without and be better off. Or maybe not, who decides? Surely it shouldn't be majority as then we will approach Idiocracy level of civilization in no time with Kayne designer flip-flops getting a yay and NASA or a new semi-conductor start-up getting a may.

I think there are two problems with crypto currencies:

1) Pollution and carbon emission is not taxed but should be.

2) Regulators allowing the situation where magic token is the only way to do certain kind of trades while competition faces insurmountable mountain of regulation and requirements. If it was possible to make fast money transfer system without hiring the army of lawyers in every country you want to operate then BTC would never gain any traction.

I have yet to see this in an enterprise setting, maybe my standard for "average python dev" is too high.
Realistically, miners aren’t going to turn the equipment off as long as the ROI is positive, however narrowly. When it the ROI becomes too small to mine, they’ll sell the equipment to someone else who can run it cheaper.

The mining equipment is also diffusing into the hands of people who don’t pay their own energy bills. I’m part of an IT forum where network admins are constantly sharing stories about employees trying to hide mining equipment in the office to use the free power and cooling for pure profit. Similar situation in school dorms.

The idea of miners turning these things on only during rare times of excess grid capacity is a myth. They’re running 24/7 and they’re consuming energy that would otherwise be sent to the grid to offset fossil fuel consumption elsewhere.

I think it behooves the US and any other country serious about both climate change and extra-planetary exploration and colonization to develop a robust terrestrial nuclear power program as well as encouraging a trained cadre of nuclear engineers who can manage nuclear power sources on other planets, satellites and space-craft.
Agree completely. I think these numbers look more realistic as well: https://en.wikipedia.org/wiki/List_of_countries_by_GDP_(PPP)...

Sorry for the "downvotes are the disagree button" that you are experiencing for raising good and interesting discussion points, and frankly calling out misleading numbers that were posted. I didn't know that the average German was worse off and poorer than the average person from Greece (I guess finally the wealth transfer from Germany to Greece is being reflected in the numbers! - kidding, kind of).
The GP comment mentions the need for finding engineers with "a proven track record of delivering value", yet here we have a concern about "hiring random Java developers".

Is the industry biased against great engineers who have been working with Java for the past 20 years, even if they "deliver value" (which is pretty much impossible to determine externally)?

That’s my town! And it’s actually totally unnoticeable, 98% of people in town have no idea.

The real only effect it had on most citizens were the fires that got started at a few mines, from electrical overloads. Now it’s a big pain if you want a large load of power, which makes starting a high power demand business a lot harder around here.

We also have a ton of indoor pot farms, this is the best place in the country to grow indoors because power is so cheap.

I think it can be simultaneously a classic, especially in historical context, and very heavy-handed. It's a good film but it's also one I'm not in a big hurry to rewatch.
Trading is a soulless activity but the psychological, social and superstitious aspect of it are quite interesting. It taps deep into the fear/hope/chaos part of our brains.

Everybody is angry to see $crypto reaching 300% but when it dips back half, nobody wants it anymore, until it grows again. Trading flips our natural reflexes upside down.

The guru/superstition aspect is also something rare.. the actual knowledge of traders is really thin, but it can sound sophisticated if not advanced for the average crowd. Paired with the fact that all that is said comes with a "work 70% of the time" there's always enough room to justify errors and failures and still look like a guru to your crowd of wannabee-rich.

That said it's also a good tool to learn about calculated risk, adventurous and also balance (many start glue to their screens but with time you know how to not overspend your time like this).

As you noted, this is just your opinion - are we going to have a person or group that decides what forms of Co2 usage are most "worthy", and adjust taxes accordingly? And let's say we do go down that path - one could certainly make the argument that Bitcoin usage from folks fleeing oppressive regimes are much more worthy than Co2 used to search for aliens or participating in far out HPC research.

> Unlike actual people mining farms can be placed right next to power source so it's easier to use Nuclear / Wind / Solar / Hydro for such purposes.

While electricity transportation is an issue, it's not a huge one compared to the likes of storage and actually having something generating electricity. And, as it turns out, a lot of the mining farms just use coal (https://decrypt.co/43848/why-bitcoin-miners-dont-use-more-re...), with only around 40% of the energy coming from renewables. Even if they were only using renewables, it's still not zero carbon, since renewables also need to be built & since the total power consumption is increased, older coal plants might be used for longer.

For something, where the economic value is comparatively low.
>Every Terawatt of energy that goes into Bitcoin is a Terawatt of energy that isn’t being put into the grid to send to homes or industries or other users.

Not really. Electricity is tough to transport over distances and interconnects are expensive and have limited capacity. That's why new hampshire's retail cost for electricity is 17 cents/kWh[1] but quebec only pays 5.8 cent/kWh

One should identify professions where a little bit of programming can provide value and then offer them a simple platform based on Javascript that lets them achieve simple business goals. Deployment should be trivial, not require maintaining servers and the results of the program should be easily accessible to relevant members of the organization. I am not sure which shape this sort of platform would take. It wouldn't be far off from Google spreadsheets where you can write arbitrary Javascript but that's just a starting point. People should be able to click a simple app together over the course of a single day and write code for the interactions.

I know that this is very similar to no code platforms but I personally don't see the need to avoid code. The value is in avoiding the need to maintain a wide variety of skills that are merely a side effect of creating and deploying an app. Having a solid foundation in programming and databases but not in all the other skills that make software engineering "engineering", is where I see the most value.

For someone who only derives value from programming, the need to learn CSS, HTML, what version control is, what testing is, how to deploy software, learn a backend framework, learn a frontend framework etc is just a barrier to entry for these individuals.
The mining GPUs that they announced aren’t based on Ampere but on Turing AFAIK from the hash rate numbers that they gave.

I made a python library/framework for processing images and frames of videos. There is a command line tool to use some built-in functions, and it can be used as a library to create a pipeline of custom operations on images as numpy arrays.

Employees are hired guns. Employees want a tolerable job and a good salary while the executives and owners want to maximize profits.

If programmers can act with “complete entitlement” sometimes it’s only because they are some of the few workers who can demand something from their jobs, even without a union backing them. Most workers do not have that privilege/leverage.
"you could buy electricity for around 2.5 cents per kilowatt." this is a typo. they meant 2.5 cents per kilowatt hour.

i think its really interesting that elon musk has changed his public stance on bitcoin. originally, and for a long time, he described bitcoin as an alternative to cash but not an alternative to centralized banking because the primary purpose of money is to act as a database or tool for resource allocation. i had never thought of it that way and it intrigued me. overall he was basically dismissive of crypto. but then recently he has endorsed bitcoin, offered to buy out dogecoin investors and other things. and he hasnt elaborated on why he turned around, and joe rogan was too stupid to ask him when he came on the podcast recently.

Does this tool help repressive governments track people across accounts? That’s sure what it looks like.
I'm sure people PW is working on that, but the failure rates on commercial aircraft parts are already ridiculously low. Bad things will always happen.
Social media might be an amplifier, but the vehemence with which proponents of crypto defend its legitimacy reminds me of the people who defend MLMs. If you say "hey, isn't this a pyramid scheme?" to folks who have managed to slip into a profitable tier of the... well.. pyramid, they immediately lash out with circular claims like "obviously this isn't a pyramid scheme, because those are illegal!"

So yeah, everyone defending crypto is trying to bootstrap the illusion of its value as anything while simultaneously trying to un-map it from comparisons to recognizable scams. They have more dollars than they should tied to both of these dreams.

It was a calculated risk. Since the company I was working for, at the time, was never going to use Swift, my "bread and butter" was at no risk, whatsoever. We were a C++ shop. I just started working with it on nights and weekends.

Being a C++ shop, however, we were quite familiar with Lattner and LLVM, so we were aware of his propensity for WIN. That gave me some confidence, going forward. Also, Apple didn't just announce a language. They also announced a full system API, as well as a product roadmap. The API showed they were serious about it. Those don't come in Cracker Jack boxes. They take some serious work and investment.

It was definitely a risk, but I'm a conservative, scarred veteran of many errors in judgment (can you say "OpenDoc"? I knew you could!). I wasn't about to run into a burning dumpster, half-assed, and I thought it was worth it. I knew it would take four or five years to mature, and it has. I tend to play the long game. I learned that, from all those years, working with the Japanese.
