A system that can sense when it is in a failure mode is analogous to a “detector” in the Neyman-Pearson sense. A detector that says it is OK when it is actually in a failure condition is said to have a missed detection (MD).

OTOH, if you say you’ve failed when you haven’t, that’s a false alarm (FA).

In general, there is a trade-off between MD and FA. You can drive MD probability to near-zero, but typically at a cost in FA.

Again in general, you can’t claim that you can drive MD to zero (other than by also driving FA probability to one) without knowing more about the specifics of the problem. Here, that would be the sensors, etc.

In particular, for systems with noisy, continuous data inputs and continuous state spaces -- not even considering real-world messiness -- I would be surprised if you could drive PD to zero without a very high cost in FA probability.

As a humbling example, you cannot do this even for detection of whether a signal is present in Gaussian noise. (I.e., PD = 1 is only achievable with PFA = 1!) PD = 1 is a very high standard in any probabilistic system.

Discrete-input systems can behave differently.

It used to be a Java applet, now rewritten in JavaScript. Sadly, the Java version vastly outperforms the JS one, at least on my machine, but Java applets are annoying to run nowadays
I think in your case its more likely they mass mailed a neighborhood minus their cable subscribers.
I wish people understood this progression and like learning happened on this curve.
It matters quite a lot when you claim one is "far superior" to others.
I will sometimes check the local college's course on a given subject and obtain some/all of the required book list - I do quite a bit of private study.
The right to be forgotten is meant to protect individuals' privacy. You sound as if you believe that a world in which all knowledge was public forever would be a better world. I disagree with this and think that we have to weigh it with individual privacy and safety. Not to mention the fact that these search engines are not 100% accurate, so it would be beneficial at least to allow people to remove inaccurate sources.

Embarrassing / reputation-affecting knowledge being available to the public forever is not the same as truth being available. Especially now that we see how engines like Youtube go out of their way to offer extreme and provocative information, we should not leave it to search engines to be unregulated sources of information about individuals. Search engines will not tell your employers that you work diligently everyday but they will show an offensive tweet of yours from 2007 if that's what gets clicks and reactions.
Or you can buy a Chinese clone off aliexpress instead.

If I were a gambling man, I'd bet that would just lead to "data warehouse" subsidiaries that would hold the liability. In case of a leak, they'd "go broke", and another would be spun up in its place. Same thing is happening with temp agencies to shield employers from workplace injury liability.

http://projects.thestar.com/temp-employment-agencies/

I completely agree with you. Shit security should cost money. I just think it has to be something like data leak liability insurance. The costs of having shitty security would be reflected in higher insurance premiums. That way, financial math would be firmly on the side of keeping data secure, instead of limiting exposure via corporate shell games.
I have nothing to discuss but I wanna say that I loved Game Programming Patterns and I am really looking forward to read Crafting Interpreters!

I would envision this system to be something such as:

We have a set of standards that define what negligence looks like for data breaches, security, etc. If a company is found to not adhere to these standards they would be found negligent and assessed some financial penalty.

If a company is found to be adhering to the standards, and is hit by a 0-day, the financial penalty would be negligible or 0.
Silent Spring Institute | Newton, MA | ONSITE | Software Engineer

We’re looking for a web application engineer to lead our efforts to design digital tools to communicate research about harmful chemicals in everyday environments.

We measure chemical levels in people’s environments and in their bodies—even a New York Times columnist Nicholas Kristof was tested in one of our studies: http://nyti.ms/2CdcyQ4! We built a web application to help us return individual results in an understandable way to the people who were tested. We need your help turning it into a scalable tool that can be used by more studies to reach tens of thousands of participants. Here’s a description of some of our work so far: https://ehp.niehs.nih.gov/EHP702/.

Silent Spring is relentlessly asking tough questions about the chemicals in our homes and in the products we buy. You’ll be there with us, helping us communicate our findings to create conscious consumers and healthier communities.

You will have opportunities to develop new software tools or lead data science projects, for example, analyzing environmental health data, developing new R packages, or creating novel visualizations of our unique datasets. You will help develop new smartphone tools, like Detox Me (https://silentspring.org/detoxme/) to collect data on the products people are using and track interventions to their reduce exposures.

This is a full time position. We offer competitive salaries, 4 weeks vacation plus holidays, health insurance, and other benefits.

>But I think it would be an overall net negative for abuse in hiding truly relevant information.

You say that, but according to some reports, only 5% of requests to Google to remove personal information from search results comes from high-profile figures (politicians and the like), the rest is just ordinary people [1]. I know that there is a huge selection bias going on here, but I'm not sure you can discount the data point just based off of that.

How you mean "even in Finland" and "edged out"? Finland resisted Russification when under Russian rule and was more on the Swedish and German language orbit before English took over after WWII.
You don't commit them to Venmo's repos. You make a Venmo-like system controlled by one or more cooperating non-profits acting in countries with strong legal systems for dealing with financial fraud. The protocol and code are open. The charter of the non-profits addresses common concerns about fees, disputes, and so on.

In other words, you use established forms of law and incentives to make organizations that protect their members' interests. You can further decentralize the scheme by having diverse sets of such organizations that have to agree on changes for participation to continue. Each problem is solved in the simplest, most-legally/technically-proven way possible. One can also make the individual customers voting members on things like charter changes that can add more protections later.

"why deal with the middle-persons?"

The author of the original article addressed that. Even the crypocurrencies have middle persons don't most of the stuff that middle-persons do in traditional systems. They're just getting worse results so far in the new model.
I think this is how we should revamp science education. Teach people how to examine the evidence and how one can fool themselves. Less inclined plane problems, more scientific reasoning.
I'd like to see some numbers on how many Google search users understand that the top of page links are ads. Personally, those seem more deceptive.
This is a somewhat misguided article.

Your ISP does not have access to most of your communication, social media usage and searches as that runs thru https.

That is why Facebook and others is completely blocked in China. Had the national carriers been able to surveil and block select communication they would have been asked to do so by the government.

Secondly an ISP charges you a subscription and that is their revenue model. They are not incentivised to build an elaborate profile on your in order to deliver advertisement.

Thirdly ISPs in most countries are required by law to support the police with surveillance information. That is done in transparent way (you can read the laws and ask your politicians).

This police support has always existed sinces the days of the tele monopolies. However now that more communication runs via internet, https and social media, it creates this strange inbalance where the police cannnot get the same access to Facebook (or similar) communication as they can to SMS or voice communication.

Also Facebook provides different level of access to the NSA, the police in Denmark and the police in Myanmar. And do that in a non-transparent manner.

On a desktop computer the power consumption difference is utterly irrelevant. Who cares about a few extra watts when your GPU is guzzling a hundred?
Yes, that's true. I suppose for me, the deception starts at the very beginning from Messenger's UI, which makes it look like any other texting app which uses local storage.
It does, though. The problem is that the most generally notable thing about a boring person who committed a serious crime 20 years ago is in fact the serious crime that they committed 20 years ago.

Put another way, if I put the name of my new neighbor into Google, the resulting webpage I would in fact most want to see as the result would definitely be the article on the murder they committed 20 years ago, even though they have a Facebook page that was updated 10 minutes ago. Facebook page can be result number 2.

If Google didn't show that result at all because it happened 20 years ago, and that person never did anything else notable more recently, I would consider Google to be a little broken.
This is not the time nor thread for a debate on the merits of vaccination, and I'm not in a good enough mood for it right now anyway. If someone honestly believes that 1 in 100 people is going to be harmed by a vaccine, and that the number harmed by refusing vaccinations is less than 1 in 100, then there's probably nothing I could say nor any literature I could cite which would change their mind.
It seems trivial but I think it's important to discuss the aesthetic of these types of things. It's not to nitpick, it's not to make fun of a person or belittle their work (I think most people here agree it's a great post!), it's to engage in a communal discussion about what we learned here so we can apply it elsewhere. Isn't that still in the spirit of HN?

I don't find the parent comment to be the most constructive example but, ignoring the subjective criticism about the jokes, I agree there's something unusually distracting about the format.

For example, the bunnies that highlight content on the right-hand side? If you're reading the entire post, you're going to read some sentences twice over -- So why are these here? For summary? Why couldn't the summary be in a more accessible area like the top?
The +100 that you get for signing up on a new subdomain is supposed to get you over that hump. But I don't remember how much rep you need to get the signup bonus.
You assume that you need to tag manually. You assume that you are forced to do so. Currently, it's perfectly possible to put all files in a single folder. Your OS will be happy about that (except maybe some technical limitation of max filecount of a folder).
"MLF Lullaby" is another absolute gem.
Indeed -- FB will not have a hand in the solution. Cracking the micropayments egg might be the new game that unseats the adtech scourge. One can hope.
You want to go in the other direction - ultra violet. There are LEDs that are in the 360-380nm range that don't produce visible light, but will still charge glow-in-the-dark materials. The higher the frequency, the less efficient it will be, however, and below 320nm they can be hazardous to skin or eyes.
Avoid first principles (to start with), instead focus on a domain you're interested in and buy a DIY kit from a vendor in that domain to solve a niche application. Repeat 3-10 times. Start dabbling in other domains. If you have a question, youtube it.

The way a lot of people get into electronics, as a hobby, is wanting a piece of hardware for a simple application, seeing existing solutions are very expensive, and discovering a community of people building their own solutions.

The way a lot of people get out of electronics, as a hobby, is loosing interest. Seeing something you built come to life is a great way to maintain interest, getting stuck in theory and first principals may delay that gratification long enough to loose interest. Later on it's fantastic for building something new from scratch that no one has seen before (even more gratifying.)

For every generation this is different so depending how old the person you're asking you'll likely get a different 'stock answer' about how they got into it.

In the 50's it was radio equipment. In the 60' was home built hi-fi. In the 70's it was kit computers. In the 80's it was a lot of radio controlled aircraft. In the 90's a lot of car tuning. In the 2000's it was modchips for video game consoles. In the 2010's a lot of stuff with Arduinos for smarthome, smart clothing, art projects. The details and exact time periods may vary a bit but the general idea is you get something tailored to your needs better and cheaper than buying off the shelf.

A good place to start is find a project someone else has done and written up, recreate it, modify it, then publish your twist on it. Repeat. For instance, here is a good starting point to add custom mood-lighting to your home: https://learn.adafruit.com/adafruit-neopixel-uberguide

Keep a journal of things you have open questions about as you're going through these projects on dropbox paper (for instance) and fill them in with knowledge by asking on forums, stack exchanges, youtube, here and elsewhere.
It should be noted im not sticking up for Trump, just addressing the idea of attributing a company bankruptcy to company owners as if they personally filed bankruptcy, as done by OP.

Still if you want to attribute the bankruptcies of companies to Trump personally because he was CEO...post a link, because I don’t think Trump was an employee of these companies at all, much less responsible for day to day operations of the casinos as CEO.

He was an owner for sure and likely sat on the board, not unlike many SV investors and VCs of startups that fail everyday.

> In my opinion the real solution here is to be more understanding to stupid things people have done in the past.

If you think the real solution is to change the way the world thinks about, and judges, everyone else then you're being remarkably naive.
These days it is a lot easier to get a good grounding in electronics. I would recommend you get a copy of The Art of Electronics by Horowitz and Hill, and ideally the teacher's manual (which has answers for many of the exercises).

Then get a simple "combo" tool (oscilloscope, signal generator, power supply, digital multimeter) like the OpenScope MZ[1] or the Espotek Labrador[2]. Add a handful of components, a wireless breadboard and some jumpers and you've got enough to do most of the labwork that the first few years of an undergraduate EE program can do.

If you can find an old Maxitronic "n00 in 1 electronics projects" kit[3] they give you a pretty solid platform for building different circuits that you could analyze fairly completely with the USB attached lab instruments.

Depending on how it goes (if you're doing circuits from the all in one kit or building them out of the Art of Electronics book) you can look at how things interact and get a solid feel for things.

This is what I've started with, too. Make: Electronics, Make: More Electronics, and the 3-volume Encyclopedia of electronic components by Charles Platt are really great.

The 8-Bit Computer video series by Ben Eater (reshared on HN recently, https://eater.net/8bit/) was the first thing I saw which ignited a passion for understanding the hardware underpinnings of computing.

ElectroBoom, GreatScott, EEVBlog, Julian Ilett, and Adafruit YouTube channels are really great, too.
That's certainly what they're doing with the buildings. The dancing man and face animations look like frame-by-frame tho (which is why they are likely video I would imagine)

That said if they can do just non-organic forms well and leave organics to polygons - that would be pretty incredible.
I find myself becoming increasingly worried about the future. My quality of life _right now_ is pretty good. But last year, I was part of a massive layoff (whole company shut down with no notice) and I found myself out of work for months. And I'm competitive: I have a master's degree in CS, decades of experience, up-to-date "skills" in a market that is supposedly facing a talent shortage - yet I found myself rejected out-of-hand, sometimes without even an interview, from dozens of positions that I was 100+% qualified for. I can't help but wonder - if it's this bad for _me_, how bad must it be for people who have aren't quite as squeaky clean as I am?
Also, if something goes wrong it's your fault anyways because you're supposed to keep 100% of your attention on the road.
I actually never considered the astronomical symbols, that would work too. Not sure I would use emoji though, I mean, at least with Chinese writing it is still writing and once you know how, they're trivial to write, and in the case of year/day/month, about as trivial as any letter of the alphabet.
You're post nicely summarizes the dual nature of the evolution fo the C++ standard: it gets more complex in certain ways, so the language hopefully gets simpler in other ways.

In think the GP was correct in pointing out that the ways in which the language is getting more complex is a problem for implementations of the compiler and/or the standard C++ library.

You may be correct that the GP was unfairly calling the committee "eager" to make the language more complex. But perhaps we can agree that the language is becoming more complex, and that the complexity comes at a cost.
Weird coincidence: this post uses Sputter, an EVM implementation written in Clojure, and there's a Clojure-inspired Lisp named "Sputter" at the top of /r/golang right now. Threw me for a loop. Maybe with some tweaking, you could run Sputter in Sputter?
One aspect is the physical thing, try some soldering kits where you do simple through-hole components on a single-layer PCB. While this is more part of the manufacturing and less of the designing and theory, it does give you a great sense of accomplishment when you make your first few circuits work.

While there are many ways to connect components like breadboards and stripboard, and many modern and digital versions of circuits, getting some experience with basics, even something as simple as a low-component flip-flop to flash one or two lights, will help you translate thought and theory into knowledge and experience.
I'm sorry but if your friend spent $80k on a development company and didn't do enough due dil to ensure that the company he was spending all of that money with wasn't outsourcing it - that's on him.

There are a dozen basic things he could have done in order to ensure that he wasn't stiffed. Off the top of my head:

- Visiting the offices meeting the team, including those people specifically assigned to his project

- Requesting staged payments so he pays as phases are met and not prior to receiving any deliverables

- Checking the contract to ensure there's no mention of outsourcing. Did he even check the contract at all?

- Getting references from former customers to ensure the validity of any claims made by the development firm

- Searching online for feedback and reviews about the firm

- Just asking questions in general. "Where is my app going to be developed and who by?" seems like an obvious one before you spend nearly a hundred thousand dollars

Edit: Looking at your post history you seem to be associated with a software development company. Did you not speak with your friend about his decision to spend an extraordinary amount on a development project ahead of him getting in this mess?
Good to see Western Digital will stay relevant. After years of buying their products I was concerned they'd fade into obscurity without a viable SSD product.

Conner got absorbed by Seagage. Micropolis rebranded and went bankrupt. Maxtor got sponged up by Western Digital. Hard to bet on a horse that lasts.
Best advice here. Totally agree.

With respect to oscillators, the old saying of “amplifiers oscillate; oscillators don’t” comes to mind. Electronics is a cruel and unforgiving field.

Also burn myself and let the magic smoke out and I’m apparently qualified in this field. Go figure :)

A broken Tektronix scope will teach you more about electronics than a textbook too. I think I’ve had about 20 of the things over the years.
I didn't see in the description or the demo: What's the frame rate of this display?
To which Apple would basically go "...yeah, because we respect users privacy" and shrug.

Google would look pretty bad if it continued to complain at that point.
That's a little disingenuous. Intel's 700 series SSD does not have anomalously high power. The Optane SSD, based on a completely different technology, has power consumption that is higher but is the top performer in many other metrics.
>cant deny it does a lot of good for a lot of people

I'm not convinced. On the surface the connectivity seems good but I've seen it poison so many people into bubble-thinking that I think it's doing far more damage than good.
That's really interesting. Does that mean then that the i in words like pai and イェス is classified as a consonant? I've seen ヴ - a variation of ウ (u) to simulate v, but had never thought of i as a potential consonant.
The plain HTML example is a bit of a straw-man. It's beyond "dated", being a faux pas for all but the most ascetic of users.

My interpretation of "resources" here would be time / money. Making sure a site is accessible by everyone takes effort which is difficult to justify, particularly if you're already stretched to capacity.
Well, being part of the problem doesn't prevent one from complaining about the problem.

But I see interesting stats in my network panel:

HTML - 33.25K

CSS - 65.89K (the bulk of which is Twitter, which looks to be the same stylesheet loaded multiple times; 3.2K without Twitter)

JS - 53.62K (it appears all of it is Twitter)

Images - 658.75K

Media - 206.12K

Stop using Twitter's code and build for users turning off images/media gets you a half-decent loading website.
