Cobalt founder here.

I was initially skeptical... but Cobalt was a problem-centric creation. We started the company after speaking with security practitioners who were clamoring for after-hours coverage & insisted that cameras & access control just couldn't provide the responsiveness & customer service that their organizations demanded. CCTV cameras are great for entry and egress. But they suffer from a host of issues: extremely costly to install, upgrade, maintain, and monitor (upto $75/mo/stream); are seldomly upgraded (analog cameras are still common!); huge bandwidth consumption to cover large areas; provide no real-time responsiveness; and are only used after the fact for investigations. But guards were just so expensive -- so companies just left major gaps in their security coverage.

We see the robots as a compliment to existing static infrastructure, where the systems automatically communicate & work together. In fact, some of these systems are built into the robots too: cameras (obviously), access control badge reader, and a heck of a lot of compute & other sensors. The concept is quite simple: Mobility is becoming increasingly cheap, and enables you to reposition your most-capable resources to the right place at right time. It's the most capable edge sensing & computation feasible, and the human-in-the-loop lets you provide a host of other capabilities too. In effect, we're allowing a single, remote person to be in many locations at once -- particularly during the low-utilization after hours (nights, weekends, & holidays). It's similar to the force multiplication that CCTV provided decades ago!

I'm not an expert on personality so won't disagree (except to say that I am a little sceptical of a static personality profile actually existing and I think people who always vote a certain way would be the easiest to regress and also the most useless to target).
As I said in another post, it really depends on what part of your privacy you are trying to protect. It is also a mistake to think of anything on the internet as a private forum.
Creating Laws for Computer Security (2016)
The suggestion that these countries are doomed due to population decline is complete nonsense, as Japan has shown. Automation is enabling less people to have to work to maintain the same standard of living.

As you said worst case scenario immigrants could fill in the gap (certainly no shortage of people trying to immigrate to western Europe). Social cohesion could go down, but that doesn't mean the only option is American style "every man for themselves" hypercapitalism.
Ask HN: Like Patreon but for donors?
I'm looking for a service where I could set up a monthly subscription to bill my credit card a certain amount. Then I could go into a control panel and assign a certain amount/percentage to various nonprofit groups or websites. The service would take care of everything, doling out the money to the organizations for a small fee, possibly even anonymously to prevent getting buried in email and notifications. Having all the tax deduction info in one place would be nice too.

So with Patreon where I might donate $5/mo, the service I'm thinking of would more likely be in the $20/mo, $100/mo or higher range and go towards more pressing causes like curing diseases and preventing environmental catastrophes.

I've entered midlife and want to help the world, especially in these times. But it's hard to find the energy to get involved so I would feel better donating. I searched the web and couldn't really find a service that did everything and that's as user-friendly as Patreon so thought I'd ask here. Thanks for any help you can provide.
Why do you denigrate the job of management? Without it the organization doesn't function.

Leadership without management is useless.
It's easy to see why people would be irritated, but at the same time, if a company is losing vast amounts of money providing a service, then it's inevitable they're going to start getting creative about charging more.
Let's say I take age and income of everyone in a city and train a regression model that predicts income from age. The model has slope and intercept that "encode" the information from all the people.

It would not be possible to make inferences about the income of any particular person from the slope and intercept, so it would be ok to share those values in, say, a journal article, even though disclosing income of a particular person would not be ok.
Imposition of any penalty is a conviction unless there is a voluntary plea. Charge is absolutely not what he meant, especially since that was a base he already explicitly covered.
The fire seems pretty severe too. I wonder what caused the battery containment to fail?
And I'd wager the Linux kernel has become more complex in the past couple decades too. But so what?

This is Clickbait. the website is known to publish such article. Don't give them a click.
What that has to do with anything? The author didn't advocate for reinventing the database or operating system in application code.

Also, Rust is very much an antithesis of write-only code; it's specifically aimed for programming at large.
It’s worth noting that C++ has been adopting python’s functional attributes, from range-based loops, <algorithm> , duck-typing, and fold expressions, to libraries supporting Python’s style more directly. Range-v3 [0] and cppitertools [1] stand out to me. The former is in a current proposal for inclusion in the C++20 standard.

Code Craft: What Is It, and Why Do You Need It?
Thanks for the reminder. We were seeing how the LP converted before updating the rest of the site.. several months ago :)

That goes with the job when you're marking a non-web service - the website is quite distinct from the product and so doesn't see the same kind of attention or have the same kind of urgency.
It is reasonable to assume that a marketing message written with the profile of the targeted person in mind works better than generic message.

In Facebook campaigns you can use certain things, such as user's interest, to select who sees your message.

I'm not an expert on Facebook analytics, but I believe you can get pretty good stats on how your campaigns are working, how much promoted posts get shared etc.

This sounds like the holy grail for advertising. You get to write your message for certain profile and get quick feedback how it worked. Even if the system is not perfect, you would have an advantage compared to somebody else who is spending the same amount of money and not using similar targeting.

Maybe their model also allowed them to find social influencers with many followers. Being able to targer these people and get them to share your message would be really good.

The article compares this to the effectiveness of traditional voter targeting methods. I'm not sure what the parameters used on those are, but maybe all of them are not available on FB, justifying the need for something else.
Mainly because it makes boatloads more money than a single cookie cutter option.

Yep. When I went to high school, literally no one showered. I never saw a single person shower after gym class.

The thing that baffles me about it, is that if you're going to do physical activity like that, a shower after should be mandatory unless you are going home. Otherwise it's pretty gross. The result will be people not trying hard in gym, or people being unsanitary.

I guess this is all because we're ashamed of our bodies or afraid of sexual perverts? What the hell happened to us that we are this way?

I would have been afraid to shower in high school, the way it was. I have since showered in front of many strangers in the military and nothing bad has ever happened to me as a result. If you do have something odd happen, then that should be dealt with. But come on man, high school is not a prison. You are pretty safe to take a shower there.

tl;dr our society would rather be dirty and gross than see the naked bodies of our peers or be seen.
Really they should have some kind of flag when they get a high number of autopilot disconnects ( or steering overrides) happening in the same place. I had to disconnect every day because it ignored temporary lane stripe markings, and it never improves, despite Tesla’s claim of fleet learning.

Seems an obvious way to improve: look at where your drivers are overriding your system.

And what's the significance of this? I'm genuinely puzzled.

I think you can't even trace all of the effects, so it can be neither proven nor disproven. You would need to study something much simpler than human beings.

And it might be more accurate to say the POTENTIAL is what scales. And this is one more technology that some people don't exploit at all and that others make the most of.

But it is right enough to describe the gist of the situation.

TiDB provides many some ways to let the deployment easier. If you just want to have a try on the single machine, we provide docker-compose (https://github.com/pingcap/tidb-docker-compose). But if you don't like docker, the single binary may be easier.

For the business users, we support ansible and K8s deployment, both can help them run the TiDB easily and quickly in production. The deployment is not a problem so far.

IMO, for the distributed system, if you need to operate many instances (10, 100 or even more), what you pay attention to most is not whether the instance is one single binary or not, but is how to operate all these easily. At that time, there is no much difference.
I thought that eGPUs work through stuff like thunderbolt, where you're basically using a PCI Express port, so the slowness would only come from the length of cables relative to an internal GPU?

Fact is practically everyone who makes an impact large enough to be remembered is one kind of asshole or another. That's just how it is, people aren't perfect, and if even our heroes can't get it right maybe we shouldn't be so hard on eachother.
There’s an unfortunate corollary to this, which is that if you try to create a libertarian paradise, you will attract three deeply virtuous people with a strong committment to the principle of universal freedom, plus millions of scoundrels. Declare that you’re going to stop holding witch hunts, and your coalition is certain to include more than its share of witches.

So while some small percent of Reddit’s average users moved over, a very large percent of its witches did. Sometimes the witchcraft was nothing worse than questioning Reddit’s political consensus. Other times, it was harassment, hate groups, and creepy porn.

When one platform (youtube) starts banning/demonetizing certain people, and you create a new platform that guarantees free expression, that new platform is going to get swarmed by the people who were banned by the incumbent platform. If YouTube's methid of selecting people be banned/demonetized is reasonably in line with what the average viewer dislikes (no necessarily what they would want banned), then when the new platform gets flooded with content from those banned from YouTube, the average viewer will find little to like on the platform.

Many people made their living off of YouTube ad revenue. Still do. You might be right that it's not the best source of income for the typical producer.

However, right now, a lot of producers are angry at YouTube for their changes to their ad policy. Now's the time to drive a large number of big content producers off of YouTube and onto your new platform, because they are actively searching for a new one. But they're motivated by the loss of their ad revenue, so they're not going to be interested in a platform that doesn't pay out ad revenue at all, that doesn't address their concerns.

Yes, it's bizarre that the article's title is falsified in the first paragraph. But maybe the title is using "endangered" in a nontechnical way.

This actually happened. A glitch with the 737-800 [0] radar altimeter caused the aircraft to go into flare (touchdown) mode at altitude resulting in the jet to basically dropping out of the sky, with rapidly decreasing airspeed.

They should have been able to fly manually and safely land with a faulty radar altimeter. It is likely the crew didn't understand the significance of the fault, even though Boeing had issued previous warnings.

My point was that "not everyone uses Chrome" is not a good response to the question of 1Password vs just using the browser's password storage (which was the original question), because Chrome isn't the only browser that saves passwords. I wasn't making any judgement on using the browser vs 1Password, though I think some people interpreted my comment as such.
I'd agree that it's in a non-technical way. Most people only think of "the endangered species list". Colloquially, "Not on" would be on Least Concern (which is every species that's not on anything higher), and anything higher than (including Vulnerable) that would be "on the list". The paragraph your parent quotes further explains the details as to what specifically was happened, which also educates people that what they may believe is a binary state (on/off the list) is actually more granular than that.

Edit to add: looks like there's a step between Least Concern and Vulnerable: Near-threatened. Also, the definition of Vulnerable is "faces a high risk of endangerment in the medium term."

Is that a likely problem for the kernel, actually? Given that there's no API stability, and the fact that syscalls are an explicit ABI anyway, I don't see how that'd matter for linux?

Recently created a third party SDK DLL in c++ and could not pass c++ types natively (unless you coupled to compiler and maybe version of compiler).
This is an excellent point, however even so you'd still have another problem. Let's say this all works great, and we get to the prices that make it feasible. You're still just adding one go around to the carbon cycle. The fuel you burn at the power plant once gets back converted to fuel once, then turns into CO2 that you can't recover when coming out the back of a 777.

The only way this technology gets to the point where it's net carbon neutral or negative is if it can process the highly dilute CO2 coming out of the free air efficiently rather than the highly concentrated CO2 coming out of a power plant. I have a sense that the dilute case is quite a bit more challenging to make work at scale and efficiently.
Exactly. Lots of bias here. They aren’t deep thinkers.

Yes, yes it is too much to ask.

I won't judge a body for being a brony, or a never-nude, or a benign cultist, or a thousand other things. I don't expect normalcy from anyone.

That said, there are unqualified evils in the world. Things and acts that slowly crush and rend human lives, making the world a darker place, more filled with despair, jealousy, and hatred. Slavery, including debt slavery, is one. The sex trade, the topic at hand, is another.

To not speak out against evils of that scale and consequence is to side with them.

Changing topics back to your quibble about infidelity: it's also evil, if on a more personal scale. Where there are vows of that weight and import, abandoning them unilaterally is ruinous to yourself, your family, those who know you, and many that you will never know or meet. It may not be a matter for the law, but it's not a silly little quirk to smile and wink at.
> C, C++ and Rust can't use a bump allocator since you need a compacting GC to do so.

It's actually very common to do this in performance oriented code. You allocate a decently sized temporary chunk of memory at the start of some period of work (say a frame of a game, or something like that) and then most/all temporary allocations are done from that in a bump pointer fashion. None of it get's freed, but in practice this isn't a big problem as long as you allocate a sufficiently large buffer (or handle overflow by allocating a second)

At the end of the period of work, you free the buffer. In the end you pay for a single malloc/free (and even this you can reduce if you re-use the buffer multiple times), despite having possibly many more allocations.

The downside is that you have some restrictions, you need to be sure none of the objects in the buffer outlives it, in C++ you probably want to ensure all the objects you allocate from it are trivially destructible, etc.

Either way, it's very common to do this sort of thing, at least in C and C++. That's partially because the system allocator is typically slow, but mostly because this sort of control is a big reason to use languages like this.

That’s reminiscent of programming safety through best practices.
I vehemently disagree with the assertion that all social media is a net negative on one's life.

First of all, there are many people who make a living off of social media, and HN itself is social media which for me personally has had a very positive impact on my life. But let's ignore this for a second.

Social media simply allows one to expand their network and influence way beyond what one could accomplish solely offline. This means being exposed to opportunities that one may have never encountered via p2p word of mouth alone, whether that be job postings, business opportunities, potential clients, business partners, knowledge, motivation, etc.

Social media of course can be a toxic waste of one's time (eg. the default Reddit homepage). Social media addiction is a serious problem that needs to be addressed. If you're compulsively checking your Facebook/Instagram every 5 minutes then that's probably a serious problem (unless you make a living off those platforms) that needs to be addressed. For the rest of us who maybe check it for 5-10 minutes in the evenings during our downtime, it's not really a big deal.

Also I'd imagine that the author is a huge recipient of the positive end of social media even if only indirectly, his blog articles and such being shared through social media in order to market his book. I discovered his work over a decade ago through his blog which I used to actively follow. So it's a little bit hypocritical of him to knock on bloggers. But I totally agree with his observation that as a whole we're losing our ability to focus, and social media addiction is a serious problem.
