Haha, I'm no physicist, so take anything I say with a grain of salt. Also, I don't think I can address everything you wrote, so apologies for picking and choosing. I'll say what I can:

> the ability to collide ... is more fundamental

That's exactly the funny thing—when physicists say "dark matter" they're saying matter that attracts but doesn't collide. They can only detect it indirectly. I think they normally want to agree with you that matter interacts with light and other matter. "Dark matter" would not be their first choice of explanations.

> the observation of the precession of Mercury constitutes a theory of general relativity

I'm going to get pedantic here and separate observation from theory, because I think it helps talk about it. Mercury was observed to precess oddly, and nobody knew why. For quite a while, the theory was that an unseen planet was doing it. So I'd phrase it only slightly differently:

> the observation of the precession of Mercury constitutes evidence for a theory of general relativity

I draw the distinction because it's central to the debate about dark matter. Weird gravity isn't a theory at all—it's an observation. And it's one physicists pretty much agree on—galaxies are definitely acting weird, with respect to their visible mass.

One possible theory to explain it is dark matter. Another is MOND. Any of them could be true—it's kind of probabilistic. For some physicists this new observation is shifting the probabilities in favor of dark matter, but it's obviously still flawed because we can't really explain dark because we have no positive confirmation of its existence outside of gravity. We'd love to find a WIMP, for example, but we haven't.

No he just releases software that kills a customer, and then publicly releases the data from the car sensors to paint the now dead customer as an incompetent driver. Sounds like exactly the person to trust with my privacy.
Does anyone know if all these recent accidents are with the old MobilEye technology or the new Nvidia system? Or was it a rumour that Tesla was moving towards Nvidia rather than MobilEye (I think MobileEye was the one that didn't want to renew their contract?)?
Doesn't seem dangerous or journalistic at all here. In the UK at least the legal system is already aware and deals quite reasonably with the right to be forgotten. Has done for years.

After a certain period a crime is considered spent and you can not be required to reveal it - except in some very limited circumstances. You'd have to reveal spent crimes if you want to join the police or become a magistrate for instance. You might want senior politicians added on this list perhaps.

If you got a fine or a short prison sentence, the period is relatively short. A long prison sentence for a serious offence is never considered spent. I think there is something of a sliding scale of how long a sentence takes to expire.

I would want essentially the same from the right to be forgotten. A citizen should not have to see Google reminding potential employers of a minor or youth offence 20 years ago when the legal system feels it expired ages ago.

Doesn't seem that complex to achieve either. So what would be the problem then?
Does anyone have any code examples / GitHub repos of Spark projects that are setup with Mill? I've been fighting with build.sbt files for a couple of years and am ready to try out some alternatives.
Hardly, most of the risk to organizations is from citizens lawsuits, not federal regulatory enforcement. There are more lawsuits than ever and as judgements and settlements have been almost entirely on the side of making sites more accessible, the risk of continuing to provide an inaccessible site increases.
Looks really good - excited to try it!

Generally before adopting a language for a new project, (for me) it would need to have things like:

- good build tool including dependency management
- reasonably fast compiler
- decent standard library
- pretty good IDE support
- clear policy about backwards compatibility
- good REPL
- good documentation (including contribution policy and license)

But there are surprisingly few language ecosystems that have all these fundamental features, even after many years (decades) of development! And many others seem to not appreciate how important they are, leading to years of tepid adoption or only niche usage at best.
I'm fairly sure I do have the technical chops to talk about the content, being very used to C++ in all it's glory, but I don't have much to add to the article: once broken down to it's intent/meaning, it's clear to me what it's about and why the code is useful. Which is why I said it's an interesting article. And why I upvoted the post.

That being said, to address your concern: this is HN, where in my experience pretty much anything can get discussed, and not-so-topnotch blog formats is one of those things. Upvotes in this case simply mean others have the same feeling with regards to the general readability of the article. Also note that, as far as I recall, there has been more than one post - not just comment - on HN exactly about this: conveying information in a proper manner is an important aspect of the internet in general. Not just bikeshedding. Even more so for technical stuff, imo.
No, you can be in business, you just can't collect that sort of data.
Once you have sufficient rep on one site, you get 100 rep on all sites which is enough to comment everywhere.

Closed-shop unions are typical where I live. My mistake on them being typical across the world.

However, even in an open shop, the collective bargaining is still limiting the employer to a single vendor with respect to those it wants to hire that are engaged with the union. The only other supply is those who want to bargain on their own, and even then you're probably not going to find too many who are willing to severely undercut the union, unless the union is on the brink of collapse anyway.

The supply is still constrained. Although perhaps not to level it is in a closed shop.

Nvidia Speaks Out Against Rising Price of GPUs Due to Crypto Mining
One of the problems I've run into with using a vpn service is that many services block IPs from common vpn services. While this may be due to abuse originating from those IPs this still seems like a lazy approach to abuse prevention.

One approach that could work around this in many cases is to run a VPS with a private VPN server on a cloud provider. This is beyond the technical ability of the average user though and costs more than most VPN services.

I re-tested a couple of the cards (notably, the Sony and Kingston cards), and they were just as painfully slow. The benchmarks took like 20 minutes (with the faster cards they only take 3-4 min).

If you use knockoff cards (no brand at all, like one that came with one of my cheap drones), the performance is so abysmally slow you might think the Pi locked up for a few hours.
Parts are KEY!!!

Crucial Items.

- A real soldering station.

- Solder

- ALL THE RESISTORS

- ALL THE WIRES (Solid core is really handy for mocking with breadboards

- A good multimeter

- A good power supply

- Breadboards

- Shrink tube

I think that covers the main things. Also nice to have are

- Heat gun

- fume hood (this is overkill for a hobbyist probably)

- Oscilloscope (I hear they are getting nearly affordable)

- Crimps (molex)

- A real crimping tool (Not pliers. One of the ratcheting ones.)

- All the other stuff I forgot about.
FWIW, this is like saying "how do I self-learn programming?" - in that there is some common underlying theory, and then specific branches you travel down. it helps to have a goal or project, so it anchors you down one of those roads.

I was schooled in electronics for 5 years - I have the fundamentals down enough that I can reason about things. I can draw the schematic for a power supply, but I couldn't tell you what sort of capacitive or inductive circuitry specifications would be needed.

On the other hand, i'm building a MTG card sorting machine; and while i've never controlled relays and stepper motors before with software, I know enough that I can fill-in-the-blanks and what sort of issues to be mindful of.

So projects helps a lot - always be tinkering with something or somethings. Watching youtube channels (like aVe) that are tinker-focused and do experiments and explore electronics theory and applications - that can help a lot too.

Also, checkout a hamfest if there's any near you coming up. You see all sorts of crazy stuff there that can inspire all sorts of projects. Just don't go with too much money or room in your car.
This seems to be a common thing across all online support communities, even ones where the software company has outsourced support to their community. I'd love to see a solution to it, as it makes discussions incredibly frustrating to read.
FB (and other data collection businesses) pose a greater threat because they have direct access to your content rather than passive streams of increasingly encrypted data. And web trackers get access to your browsing behavior even if you aren't a user in a way that gives them more oversight on TLS connections since they're embedded (somewhat unwittingly) by webpages throughout the internet.

TLS limits what your ISP can see. So until they block encrypted traffic it doesn't scare me too much.
Cooling would be more of an issue in the vacuum of space. Even my little engraving laser requires water cooling, that satellite would be covered in radiators. Don't forget the targeting system needs power and cooling too.

Mirrors... Shooting from above is the "cleanest" shot. Hitting debris at an angle will change the debris orbital path (non-deterministic for rotating junk) until it re-enters the atmosphere. That's a risk for space control, which relies on predictable orbits.

Capacitors are a solution if the laser requires far more energy than the solar panels, but that lowers the cleanup rate of one satellite.

Like I said, the idea works. However, there are tradeoffs between price and results - I don't know that there's a practical balance.
If you already trust the accountant, he can set up a conventional database, and you can look stuff up there. Much simpler and cheaper.

A blockchain-based shared ledger is only useful in case the participants don't trust each other. In which case you cannot do anything with it to help detecting counterfeits.
I'm not saying it was developed for Zuck in the last few days. Yeah, I think it was definitely an internal tool or secret ability before. But one could easily imagine that they really were going to roll it out to public users sometime -- and now they're rolling it out earlier to save some face.

Back in '77, op-amps weren't as good as they are now in terms of PSRR and output power. That push-pull output stage is quaint but given that they wrapped it in the feedback loop of the last op-amp, it may have been a necessity at the time.
It's better than the no-name cards, and even slightly faster than some of the secondary-brand cards (Transcend, PNY, Sony, Kingston, Toshiba).

It's not a terrible choice for a starter card, but you can get the Evo+ cheaper for the same capacity, if you can stand to flash it yourself :)

That site is still not for discussions. It is however a site for Q&A on the software development process and architecture which tends to softer questions.

There really is a feeling of "too little, too late".

Not in the sense FB cannot make improvements. Of course they can.

What is too little, too late is reversing the direction that the Zuckerberg story has taken.

The media can build someone up and they can also destroy someone.

As the recent Rolling Stone article suggested in no uncertain terms, there has been great damage done to media and journalism (and arguably to society) by having FB as a "filter" between the reader and the news source.

They have not managed the relationships well enough it seems.

Have a look at this article:

https://www.theguardian.com/technology/2018/apr/06/mark-zuck...

Anecdotally I have heard Zuckerberg discussed in the ways described in this article. I have no doubt he was trying to carefully craft an image for the American public.

But, today, who can trust this young man who has the personal lives of billions of people on his servers... now that they have seen how he reacts in a crisis? (Perhaps we should say "fails to react".)

There is a certain irony I see in the failure of Zuckerbergs PR team. Someone who has been in PR for many years once explained to me the effect of FB on PR. Needless to say, it wasnt positive. PR traditionally relied on the media and its ability to reach the targeted audience. To a large extent, FB controls this now.

Whether any of this will matter long-term, who knows? Ask Wall Street?

But if and when FB assures us that they have everything under control, I will have doubts. This is an evolving story. We are seeing only the tip of the FB iceberg.
Sure. You can have daily sprints if you like --- if you know what you're doing.

The rule with frameworks is this: the more time you spend thinking and screwing around with the framework, the more you're either doing it wrong or it's hurting more than helping. Scrum/Agile should just work, just like your C compiler just works. It's a tool that operates almost invisibly in the background while you make stuff people want. If it takes a long time to work with it, or you spend a lot of time fussing with it or arguing over whether you're doing it right or not? You've got something backwards somewhere.

People end up with long sprints and tons of meetings either usually because they don't understand what they're doing or they're doing it the wrong way. Personally I prefer week or less sprints. Anything else tends to grow a bunch of meeting BS over time that's non-productive.
Sidestepping your title authenticity question a bit: the risk of going with the clickbait headline is that you simply won't get any substantive comments because a critical mass will skip the posting -- that may have happened here (4h in and nothing yet). Meanwhile there is a third option: find another outlet that covered the topic is a less clickbaity fashion.
It raises the question...what other liberties did Zuckerberg take on facebook?

The reddit thing was petty, but didn't really do any material damage. Uber's God View was more troubling...showing how you could track politicians/celebs usage of the platform.

But facebook...this admission opens the door to speculation that Zuckerberg could have theoretically taken ad hoc 'God Mode' actions against users of his personal interest...read their messages, view their activity logs, etc. Only Facebook knows, for now.
Coming from an amateur bodybuilder yes it is everywhere. I've been on for a couple years now. Once you've done some cycles you realize how many people use especially what is known as 'fake nattys', people who claim to not use publicly in interviews and Instagram etc but have physiques which could never be possible without gear.

Most amateur sports from what I've found such as cycling (bikes not gear), martial arts, football, you can bet most people are using to some degree.

The op mentioned masters class, and there's a tight correlation there to older men being prescribed trt. A lot of people also take that and then up the dose a bit more to the point where they're running a full cycle and should be taking an AI.

That's another aspect as well where people will claim it's just trt dose, but no I'm sorry but when you got puffy nipples because of your trt dose and no AI you're on a full cycle.
> A gun in the hands of a qualified, reasonable person is a legitimate means of self defence, but I can't think of why that should apply to something like an AR-15, which is built to kill as many people as quickly as possible.

If AR-15 style weapons, which use .223 cartridges, were banned, that would still leave sporting rifles, which use the larger and more powerful .308 cartridge. That cartridge was the size used in the battle rifles of the WWI / WWII era that were standard before the evolution of the assault rifle. (Assault rifles have smaller cartridges because the range and power of the standard battle rifle cartridge was found to be unnecessary and the smaller cartridges allowed soldiers to carry a larger quantity.)

Given that, it's hard to see how an AR-15 ban is anything other than a cosmetic ban.
What the fuck. There is nothing journalistic about their compulsive instinct to archive everything (and to spend a lot of money on enabling not just crawling the web, but rather.. pretty much everything.)

This would be like like giving some average reddit.com/datahoarder/ person a right to be forgotten, except that particular person happened have to crawl pretty much the entire world and probably knows enough to get 90% of the global population to get fired, if it wanted to.
One quick question.

You talk about a VM allocating memory. In the process of constructing my own simple-as-possible VM, I figured allocation would be done by the routines involved, with the VM just providing CPU-like facilities for accessing raw memory. What are the advantages of a VM allocating memory?

Well, yeah. But on the other hand, the complaint records aren't going to be deleted even under Pai.

The complaints likely won't go anywhere anytime soon. But when Pai's successor is working to repair the damage, there's a decent chance that one of the things they'll have to do is go through the agency's records to figure out what was ignored. Having a record of the complaint will at least give them options in the future.

So file the complaint, even if it's unlikely to matter in the short-term. :)

> ISPs have to work around widespread (and growing) encryption, while Google/Facebook have your _actual_ data.

Today. But in terms of risk moving forward, I think ISPs are way worse. Two reasons:

1) I really can choose not to use Google/Facebook. There exist very solid, privacy-respecting alternatives for every service these two companies offer. It's a matter of consumer choice.

This is not the case for ISPs. If my (one) local "high-speed" ISP demands that I install a new root cert so they can MITM all my traffic, my choices are to a) capitulate, or b) find a way to live with very low-speed DSL/dial-up.

Monopoly power backed up by a vast network of cables has way more staying power than monopoly power backed up by social network effects (FB) or superior software offerings (Gmail).

2) You might argue that history demonstrates we don't have to worry about ISPs demanding to MITM customer traffic. But Historically, ISPs weren't incentivized to snoop because of regulatory barriers that prevented collection/use of data for advertising purposes. In the case of US ISPs, changes in regulator landscape suggest that past behavior doesn't guarantee future behavior.

It's times like these that I'd like to be able to bookmark HN conversations.
A while ago I would have recommended you get The Art of Electronics, and The Student Manual for this, and then some cheap tools and components, and then just work your way through the student manual doing all the experiments and then reading the main book to learn the theory.

That's still a good choice, but you'll notice it's getting a bit outdated.
