I find bitcoin entertaining, and incrementally so the more I have.
Better yet, build an operating system and link it to the cloud.
When you start to scale for your amount of customers and features, you have to manage caching, job queues, and more. Things frameworks like Rails or Django provide mostly OOB. If you’re using Go or Node, you’ll end up writing your own de-facto framework (even if “writing” means pulling in different libraries and gluing them together) around those features, especially in the case of micro services where you’ll want each of those things available in each service.
I don't quite understand this analogy, can you expand on what you mean?
I'm very skeptical of hydrogen as a general solution for reducing carbon emissions. It feels like greenwashing.

"As of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels"

Producing "green hydrogen" is much more expensive:

Yeah, the 1702 is a great display for the 8 and 16 bit eras of gaming and computing.

It comes down to the CRT having a tight color mask and the monitor circuits doing a good job handling the signals. And having seperate color and intensity signals was a bit ahead of it's time. Everyone else got this as s-video.
I want to avoid the downvotes, though. Downvoting is for things that are off topic or don't add to the conversation, or comments made in bad faith. Someone who just happens to be wrong may very well be commenting earnestly in good faith.
gold is a physical asset used in a [lot of stuff](https://geology.com/minerals/gold/uses-of-gold.shtml).
The thonk of an IBM PC power switch too. Not even the click-click of a newer clone's power button.
>On the Ethereum side, the cryptocurrency is used as an incentive for nodes to operate the global EVM (Ethereum Virtual Machine), which processes smart contract transactions.

You don't get paid for running a node unless you're also staking.
The hacker spirit is about curiosity and tinkering with stuff to understand how it works, it is about the beauty of imagining and exploring new ideas and building them (whether they be useful or not). The hacker spirit is not about writing crud apps to maximize business ROI for your company, it is not about trying to scrape the bottom of the barrel to find an idea (a social media app for X) to make yourself and your investors rich. As soon as money flowed into tech, everything changed, and PG was most definitely responsible for that change in part.
The people who make the decisions don't use the product. That's almost always the root cause of this stuff. I worked on a system for my state - another vendor came in and 'took over' all the functionality my system handled. Supposedly. 7 years later, my system powers the exception to the mandate to 'use system X', because... they refuse to provide the functionality that they sold the state. Contractually, "we provide feature ABC", but the reality is.. they don't. I even provided them our code to use - it was paid for with public money, they should just integrate it and then sell it to other people to make their product better. They can't even be bothered to take the code and integrate it... they prefer to continually lie and say "we provide feature ABC" when... they don't. It's beyond insane. A large majority of the people on the ground know it's bad/lacking/broken, but ... they have 0 voice in the matter.
Ask HN: Learning robotics/electronics beyond Arduino?
Background on me: I am a fairly adaptable person with a background in supply chain management but making a living as a data engineer. I've done some machine learning work, a lot of data work, and I've also done quite a bit of mathematical optimization work (LP, MIP, IP, CP). Mostly working within the Java and/or Python ecosystems, but have done a bit of Rust and F# as well.

I'm currently trying to learn electronics / robotics / control theory and I'm struggling a bit as I feel like I've fallen into a gap between extreme beginner and extreme expert. I guess to some extent that is normal, but it seems like everywhere I go for help on something new I get pushed back into the Arduino ecosystem. I'm sure it's possible to take Arduino to a much bigger level, but I'd like to learn some more intermediate concepts like:

* How to write code targeting a non-Arduino microcontroller, preferably with a newer language like Nim, Rust, or Zig (I really value the benefits of higher level languages)

* How to use an RTOS like FreeRTOS, Zephyr, or L4. More than just installing it and running Hello World... I'm looking to take advantage of their actual benefits over the OS-less alternative.

* How to interface with and control devices beyond GPIO pins and PWM protocols.

* How to write actual drivers (instead of doing everything in a `void setup/loop` construct), including any sort of design patterns or general rules for producing higher quality and more reliable and robust code.

Are there any good resources for this sort of jump out of the Arduino ecosystem? More advanced concepts that would allow for building an actual product instead of a weekend project?
They have inherent scrap value at the very least. Copper is really pricey these days and pinball machines have a LOT of wiring.

Parting out the visible bits could be lucrative too, especially if it's a desirable machine like No Good Gofers or Attack from Mars.
Yes, you have to learn how to build a minimal pom.xml to make this compile and run. IntelliJ will do this for you with its Spring Boot project template. After that, it really is this easy.

I consider the boilerplate needed to build a main.go file that starts a gRPC listener to be harder.
It's a myth that taxes are what give currency value. Plenty of currencies needed to pay taxes throughout history have hyperinflated into nothing.
Btc is a more akin to a commodity like gold, which also has no cash flow. It can’t be valued by dcf’ing cash flows, hence methods like stock to flow for valuation or comps.

Pos assets like Eth also have a running yield so you can discount cashflows on those.
Ordered queue is a priority queue, which can be implemented using a binary heap. A binary heap can be backed with a simple array, which is more cache friendly than a linked list. The worst case is O(logN) for insert and delete, only O(1) for peek. It's better than the O(N) insertion sort on the linked list.

So it comes down to believe that bitcoin trading had an entertainment value of a trillion dollars a few months ago?
Amazing. Needs soundblaster emulation though. I vaguely remember the sound from Dune II wasn't bad.
The US dollar is a medium of exchange, not an asset or an investment. You use dollars to buy things, you don't own dollars just to own dollars.
It still amazes me that people pay for plastic bottles of water!

Edit: I obviously mean in the developed world.
The COVID protests happening in China have already happened all over the West and they're far from over. It's interesting to note how the MSM acted in one case vs how it's acting now.

Without Conflict There Is No Growth
I don't think I can explain to you why this is unsettling in the same way I can't explain why abusing animals is bad, stealing is bad, or anything else is "bad". If we don't already have a shared system of morals which says "abuse of children is bad", then it seems unlikely I'm going to convince you that depictions of child abuse are bad.

To me, this is "bad" because I subscribe to a belief system that thinks abusing children is bad. Balenciaga, in their marketing, has used images which imply the abuse of children. Therefore: this is bad.
The constant combining of altcoins and bitcoin is not helpful. There's a use case that is 'money' in which the value of the object used as money is always deeply disconnected from the underlying asset value (i.e. we never trade factories and cars as money. We still don't even trade stocks as money). Bitcoin is attacking that use case head on. It has features like scarcity, no ability to stop a transaction, etc. as features over other forms of money.

Then there's a huge list of altcoins promising things that are different, are not actually different or helpful, and are really just still targeting being a money like bitcoin or the dollar except the founder of the new currency wants to be the one that centrally controls it. Thus 'crypto' is not a helpful space, but bitcoin could be.
None of this was upsetting. This sort of seems like the "why can't comedians only tell nice jokes?"

Fashion is an art form. Sometimes it makes statements and attempts at subversion.
The US dollar can be traded on very safe markets for any number of commodities fairly trivially. What can I purchase with bitcoin other than USD or other currency? Even the eshops that accept bitcoin only do so to immediately convert into fiat. Prices are still denominated in USD.
I agree that the use cases shown are not representative of the vast majority of projects. After using Tailwind for almost two years, I find the biggest strengths are: a common set of naming conventions (don't underestimate how hard it is to name classes well and consistently across projects); bundling of commonly used features (autoprefixing, purging unused classes); and how well it works with component libraries. Beyond that, Tailwind is just CSS — unlike pre-compilers like SaaS and LESS that actually extend CSS.
Personally, I’d love to see robot drones remotely apply lethal force to people breaking into vehicles, but it’ll be a long time before enough red tape will be cut to make that happen.

Yes. Docker compose is the way to go.
It’s teddy bears in chains. I mean I know I’m French which means it’s probably hard to find someone culturally less attuned with an American regarding sexuality but the whole thing seems to me like a storm in a tea cup. As I said, it’s not tasteful but that’s miles away from being scandalous.
I'm curious, if you're using CSS-in-JS already why not jump to tailwind? Its slightly more restrictive, but I've found the more opinionated style incredibly helpful.

What are the benefits you're getting from CSS-in-JS?
Benchmarks are included on Windows and Mac for: Base R, R + dplyr, R + data.table, Python + Pandas, Knime, Power Query and Easy Data Transform. Alteryx and Tableau Prep are also discussed, but benchmarks are forbidden by their licensing agreement.

While other benchmarks for ETL/data wrangling tools are available ( https://h2oai.github.io/db-benchmark/ ) they tend not to include GUI based tools such as Knime and Easy Data Transform.
Are there any plans to incorporate other video platforms in this client?
Senior front-end engineer here! I hated, HATED Tailwind for ages. It made me super angry that it was glossing over everything that makes CSS great. The ability to write great, maintainable styles seemed lost.

But after a couple of projects using Tailwind, I actually think it's a really solid way to implement styling that scales well as a project/team grows. It's maintainable because it's tightly coupled to markup (like styled APIs), has great first class support for design tokens and once you learn the syntax it can let you express specific css rules in a way that's more clear and concise.

I don't know if it'll have much staying power as the front end community continues to explore how we want to define styles. But what is clear from Tailwind's success is people want high levels of performance, styles tightly coupled to markup, a first-class way to utilise theme tokens etc.

For now if I was to start a new project, I'd likely pick Tailwind unless there was a good reason not to.
This is something of a categorical error, and I'm surprised NNT would employ such sophistry.

Plenty of things have value that are not securities or contracts or bonds subject to net present value of discounted future cash flows. Gold, precious art or houses are all valuable but have zero (or negative) value under discounted cash flow analysis.

The proper way to interpret discounted future cash flow analysis of crypto is to say that crypto isn't a security. That isn't even necessarily true, since something like an Ethereum token could in fact have future cash flows and be security-like, but it is true for Bitcoin.

The problem is that the utility of crypto in the real economy is quite low, so its price is driven almost entirely by speculation, with some niche uses like being a relatively stable medium of exchange in failed state-economies like Venezuela. If you wouldn't have a reason in a functioning economy to buy anything beyond drugs with Bitcoin (and the public nature of its ledger makes even that use case suspect), then it won't have stable prices. That's a vicious cycle undermining BTC.

If Ethereum had one or two killer apps, I have a feeling Bitcoin would become both price stable and much more valuable. But that's a big "if." Crypto kitties, NFTs and weird monkey photos aren't it.
Tales of the M1 GPU
The 060 was released[1] a full year after the Pentium and was significantly slower. It certainly wasn't a bad CPU, in an alternate universe where Motorola didn't fall as far behind on fab process as they did (or were able to find a second source to compete with Intel et. al.) you could absolutely see 68k continuing on as a dominant architecture. But in the real world of 1994, it was too little, too late, and is remembered now more as a bookend to an era than a processor design.

[1] On paper. In fact it never really "reached market" until significantly later when a few folks started shipping it in embedded contexts. The only desktop/server/bigsystem users ended up being upgrades to existing '040 designs.
There are good research jobs in industry which are serious and mathematical. However they also require you to be serious and mathematical. I’d venture to say at this stage that most “data scientists” are either self taught segues from adjacent fields or have a shallow relevant background.

The serious places don’t want you… so you end up at the place that can’t tell the difference, and the self fulfilling prophecy begins.
I am in favor of free speech. However, I can't help but think the mainstream internet activist left and right are engaged in a trolling war.

This art is probably intended to be edgy, just like the faux-satanism fashion, it's meant to rub freedom of expression in the faces of certain people the in-crowd dislikes. All that is happening is mutual provocation and outrage. The same thing is happening on Twitter with performative trolling and then people claiming that Twitter is now a threat to democracy. Obviously, that means a lot of people who claim to want free speech only want it for themselves.

This particular speech that I don't like is a threat to society

Pinball machines do have inherent value. They are made up of actual physical components that can be used for something unrelated. Granted, that inherent value is much, much lower than any price you'll see them sold for, but it is there.
Learn how DoorDash built a secure data transfer to a new payment processing vendor by establishing a private network link using AWS Direct Connect.
The problem isn't the checksum algorithm, it's that TCP/IP only protects packets in-flight. The checksums aren't kept on-disk, so errors can creep in after they've made it across the network.

Well, and also TCP/IP checksums are small enough that you'll relatively frequently see errors sneak through them. But that's not likely to be what you were noticing.
Funny, I always thought hackers were supposed to work smart and belittle those that "work hard, always", especially those doing it for a "corpo". I don't consider myself an old-time hacker, but this comment makes me laugh at the expected servitude from one such person.

I also don't get where the hacker ethos comes in when you're surrounded by barely competent fools coming out of a 6 month bootcamp and banging a quarter of a million per year, because the suits in this "larger corpo" you believe to be irrelevant are banking on growth metrics to get money in this greater fool world.
It's still not that unsettling as the parent comment tried to portray it.

I'm actually not sure what caused such a repulse from that comment, it's the usual edgy haute couture show, the way it was described in that comment made me expect a lot more than what I watched. I thought there would be some deeply unsettling stuff and was wondering how it was even allowed on a fashion show. It's just mud, some models walking around with the pieces of the season and... That's it?

The chained BDSM teddy bears with the kids pictures are actually in bad taste and more unsettling than the show but in a "how the fuck did the artistic directors think this would be viewed as?" way than anything else. Because it's truly in bad taste to try to refer to any kind of child abuse.

To me the shock portrayed by the parent comment of yours is actually a bit shocking, might be that my life's experiences made me a bit unfazed to this forced edgy bit though.
Agreed.

I've run a "data science consultancy" in some form or fashion for three years now.

When people say "data science" they mean one of three things:

(1) MLE

(2) Data Management

(3) Data Analysis or Business Intelligence (applications of the same skillsets).

(1) has a lot of ongoing innovation, be it in MLOps, autoML, mapping frontier ML to business cases, etc. Innovation is expensive if the investment strategy is unprincipled. (2) is a critical and essential part of making data a usable asset. Management is expensive if it exists solely as a control process and gatekeeps access and use. (3) is core and will never get away from the adhocs and the standard flows, but the inferences are often dubious or not logically justifiable and requires depth of statistical knowledge (rare) to do well -- and courage to call out BS.

Very few people have the depth to do all three. What I have found is that many businesses hope for capacity in all three, plus some basic SWE, in the hope that they can decrease labor expenses. Not an irrational hope, to be frank, but ultimate the iron law of business holds: you can have it good, fast, or cheap -- pick two and be happy with one.

My core observation (and one I see validated based on client interest and experience) is that this is not new and has happened before -- it is the hype cycle in action. The digitization process (including moving to digital and then moving to Web) had a similar cycle. When you treat "data science" like its a silver bullet it will generally fail to do anything but suck budget. When you embed it with your technology teams and treat it as an iterative add, as useful as devops, etc., you have a better chance for value add.
Back when it actually worked as a decentralised global ledger capable of allowing transactions without trusting a central party it was revolutionary. Then it got hijacked to discard that property and it is indeed of zero value. There are still plenty of other cryptos that actually work, but the market is so stupid, scammy and manipulated, that this hardly matters and btc acts as a giant sink of value sucking all of the air out of the room and suffocating anything else that could actually work.

I think until it's dead we're not going to see any change from that.
Yes, but Warren Buffer doesn't live in El Salvador, so the only thing he could do with BTC is sell it to someone for USD so the point still stands
So Bitcoin should be priced according to the size of the El Salvadorian economy. Not all of the economy, but the economy conducted in bitcoin. Bitcoin can't take credit for people using alternative currencies to pay their taxes in El Salvador, or using it to buy groceries, pay rent, etc.
Pretty much all high fashion is bizarre by the standards of average people who don't deal in it.

Grouping people who call it that in with people going whole hog on the moral panic serves no productive purpose other than to lend legitimacy to the moral panic.

You will eventually reap what you sow with this "everyone who has a criticism is an extremist" rhetoric.
For me its been the questionable stewardship of vscode (https://github.com/omnisharp/omnisharp-vscode/issues/5276) driving me away from vscode and the Emacs from Scratch videos from the System Crafters youtube channel driving me towards Emacs. When I was looking for alternatives I stumbled on those videos and they blew me away.

Also Emacs 28/29 has been way more welcoming and easy to get started with than when I first tried 8 or so years ago.
Yikes. No, we'd look for a shoal of fish, then throw a homemade explosive in the middle. Still horrible.
It doesn't have underlying physical assets, it does have the backing of large stable government. This is largely the same reason why the USD is more stable than, for example, the Kenyan Shilling.
I have no axe to grind, irt data science/engineering, as I have no experience in either.

However, it seems this person's biggest gripe is with good old crap management; the bane of business for hundreds of years.

This line stood out:

> Companies all over were consistently pursuing things that could be reasoned about a priori as being insane ideas– ideas any decently smart person should know wouldn’t work before they’re tried.

That pretty much summarizes why I have been told that today's companies want only young people. Us "olds," are "negative naysayers," who say things like "You know that the laws of physics forbid this, right?" or "I tried that, a couple of years ago. It didn't work out, and here's why...".

Apparently, young people are able to do the impossible, because they haven't been told it's impossible, and mixing "olds" with them, spoils the soup, by telling them it's impossible (or maybe a lot more difficult that they imagine).
You would have an immediate market for them since dollars are the only legal way to pay your taxes. Since everyone must do this, it creates a kind of Schelling point such that everyone defaults to using dollars for everything else also.

If you produce something of value in return for Bitcoin, you must still acquire dollars to pay your taxes. If you refuse, men with guns will escort you to jail. That is what ultimately backs Buffet’s preferred currency.
Theranos was exceptional in its industry, where most actors sell valuable products, have existed for decades if not centuries and will continue to do so for the foreseeable future.

BlockFi is just your typical blockchain company, a complete waste of money if not a scam, see FTX, Terra, BitConnect, MtGox and so on. An exception to the rule would be a company that's not a complete disaster run by ignorant, arrogant scammers.
Just as one data point, I have never used straight.el, package.el as it exists in even Emacs 26 is sufficient for me for all my packages. I think this is true for the majority of Emacs users that use packages.
Own assets people need. It’s a pretty simple investing philosophy.

Crypto doesn’t produce anything, nor can you buy anything with it you can’t buy with fiat except perhaps drugs online. What’s the value of magic tokens whose speciality is avoiding monetary controls for illicit goods? No one needs crypto (macro scale), so why would you buy it? Because you hope a greater fool comes along.
Even if they were shock chasing, it's just a really fucked up thing to do (and those are the mildest terms I can put it in). There are plenty of ads I see where I go "well they took it a little far but I can understand what they are trying to do". Making references to CP in photoshoot with children going many many many steps beyond just "shock chasing".
But it’s not the only one, unlike the USD
