I did notice that there wasn't any good "blue" on the grid they provided:

https://theconversation.imgix.net/files/186280/original/file...

My two monitors display the grids a bit differently, but A3 is pretty obviously red, B4 is orange, E7 is the best yellow, H4 is the best green. None of the blues look like the primary color blue though.

I took a sample of the blue colors in a paint program and they all seemed pretty far away from a proper blue. The hue is off. N4, which was presented in the article as blue, is RGB (35, 131, 172). A3 red by comparison is (190, 27, 50) and H4 green is (42, 144, 48).

As an additional test, I edited the grid, drawing rectangles of red (255, 0, 0) and blue (0, 255, 0) over each of the proximate color squares. Pure red is fairly close to A3 whereas pure blue is very different from all blue-like squares on the grid.

It feels to me that something is off about this grid, like it doesn't cover enough of the color space to encompass a proper primary blue, but I don't know enough about color theory to characterize what's wrong with it.
I am not trying to be snarky when I say this, so I'll make it longer than a single word.

No.

That is, Y! Answers was/is a great idea with terrible results. I'm not sure if it should have been moderated better, or if it should have been marketed better. Hell, maybe it should have had a basic literacy test prior to being allowed to post and answer?

I could actually come up with a few hundred ways to have made it better. We know the question and answer format works. It does on many, many sites. It failed there and, largely, that's because of the users. I'm not sure which was worse, the questions or the answers.

I'd love to be given that project and tasked with improving it. It's a great idea, but horribly implemented. I'd like to fix it because I'm fond of trying the impossible and like fixing broken things.

Improving search for it is absolutely not going to help it. No, that's not going to help in the slightest.
I agree with this.

Imagine studying about web design, accessibility and usability for many years. You feel that you have something to contribute to the design of any app.

Then the higher ups just hands you a spec and assigns you to a task to fix this bug/implement this feature without your input.

That's pretty damn demoralizing. It will just push you towards caring more about streamlining your own workflow to rather than care about the actual usability of the app.

Maybe that's the reason why there is so much interest in the in what workflow to use, what IDE/text editor to use, which languages to program in, etc.
I was just pointing out that the reference used by GP is specifically about new cars.

Also, your second reference is also about new cars. I cannot believe anyone spending ~$1000/year on a maintenance of a 'new' car. First three years while it is still covered by warranty you will need an oil/filter change once a year and no new tires. $50/year at the official dealer was the maintenance cost of the last four new cars I owned.

We know the issues around ObjectStreams and rehydrating constructors; mad gadget style vulns etc. But this is a local cache of trusted data which can only ever be touched by the app, and if an attacker is starting to mess around with your app's file storage you are already in a pretty bad situation. And, as I said, this is a placeholder for a proper DB.

In terms of whether "release and iterate" is unacceptable for secure messaging: we make it abundantly clear that the privacy protecting features are still in development and are beta quality and shouldn't be used for anything where privacy is critical. Meanwhile the idea that secure messaging products shouldn't be publicly beta'd prior to a formal GA (especially for stuff as complex as decentralised e2e crypto) feels weird at best.

If you've found fatal crashes or races in the E2E UX, please do the responsible thing and chuck an email to security@matrix.org rather than bragging about non-specifics here. Finally: Matrix's projects span a little bit more than just the Android SDK, which is admittedly mid-development still. So yes, there's loads of low-hanging optimisation work to be done and some areas of crappy code, but that's not remotely the whole picture.

One of the most neglected aspects of Marx is that he thought that capitalism was an inevitable, natural development of industry. He also thought that it was a system full of contradictions and deduced that those contradictions would eventually cause it to transform into another system, communism. Communism was already a wildly popular movement by the time Marx started writing. What he set out to do was explain why there was a conflict in which one side was called capitalism and another was called communism and how that conflict would play out.

Marx's biggest failing was that he did not consider a third possibility: fascism. Such a populist movement was inconceivable to Marx, the epitome of an enlightenment thinker.
Probably legal due to the frequencies involved, but also useless in anything but a completely radio-quiet environment (the ISM bands are specifically allocated to common interference sources --- and the only reason other wireless devices like WiFi and BlueTooth can survive there are due to processing techniques that can transmit/receive below the noise floor, like spread spectrum.)
Uber's in over 600 cities. It wins some and it loses some. But mostly it wins.

"We shall not cease from exploration, and the end of all our exploring will be to arrive where we started and know the place for the first time." — T. S. Eliot

I've often thought that the ideal post-scarcity lifestyle would be to live in giant gardens (in giant rotating space habitats no less) where we can run around hunting, gathering, telling stories around the campfire and sleeping under the stars, and occasionally spending time in the lab or workshop or in zero-g building stuff.

i.e. hunting and gathering -> agriculture -> industrialisation -> automation -> hunting and gathering (and space engineering)

To my eyes, this code is much less clear than code that uses absl mutexes. Also, to my understanding, reentrant mutexes are much slower than ordinary mutexes, and are never necessary.

But, I have been using absl mutexes for more than ten years, so I'm a bit biased.
I’m 50 and I have also been asked why I don’t use Facebook or LinkedIn.

Surely you could still use it for hints? (ie. "stroke X followed by stroke Y has a Z% higher chance of being this character rather than that one", much like some phone keyboards use the prior/next words entered to correct words so they make sense in context).
Ok. Now consider what happens with slices/arrays instead of maps.

1) for k := range list {}

2) for k, i := range list {}

In python, the equivalents are:

1) for x in lst:

2) for x, y in enumerate(lst):

So are these "the same" ? No.
If you have two charged black holes, orbiting closer until they collide, then they must emit electromagnetic radiation. I'm not sure how high is the frequency of the orbits just before the collision and how much energy they can dissipate in this way, but it's definitively not 0.

Also, he Hawking radiation is an intrinsic property of the black holes, you can't disconnect it. I doubt that anyone has calculated if the Hawking radiation increase or decrease during a black hole - black hole collision. My guess is that it increase and if you are nearby you would see a flash of light. The technical detail that the light doesn't come from inside the black holes is not meaningful. The whole black hole - black hole collision also includes all the Hawking-like radiation emitted.
VS Code is set to rule the developer world. The core and extension model is designed beautifully. While the core editor is concentrated at performance, the extensions provide feature rich functionality for each developer needs.
I'm moderately impressed, but I wonder why they would bother. I use VS Code as a powerful text editor and occasionally as a sorta JavaScript IDE. Java and .NET have fantastic IDEs already that are extremely hard to beat.

I do sometimes browse in Lynx. I'm not even ashamed to admit it.

I also will sometimes use a browser that is graphical but doesn't support much, such as Midori. If you're a Windows user, there is an obscure browser called OffByOne and I used to use that one on a regular basis.

For much of my browsing, I don't need much more than text. Sometimes, I do like images. I'll use a lightweight browser for that.

On my tablet, like I am now, I have zero non-default apps installed, and don't intend to add any. So, I'll make use of the linked site, or similar, when I find a page that I want to see and it won't behave well for Safari.

It's kind of nice to browse the web with one of the lightweight browsers. Links2 also works, as does elinks, for lightweight experiences. I think both have Windows builds and links2 can be found pre-compiled with https support - I'm pretty sure. OffByOne is the one I generally recommend. I don't think it has ever actually had a security vulnerability. I'm not sure how many people use it, but it probably totals in the double digits!

I don't actually remember how I found OffByOne? I think I may have been looking to include a basic browser in an application I was making for myself. They do have a free stand-alone product, but it wasn't open source when I last looked. That was ages ago.

No, it's precisely because it has bearing that people oppose it.

Traffic lights are green/yellow/red in the US.

They are rouge/orange/rouge in French (translation: green/orange/red).

Some languages perceive the middle color as yellow, some as orange.

Is there any part of our leviathan government left which does not indulge special interest groups and rent seekers, or mire citizens in mystifying, stultifying bureaucracy?

I've personally interacted somewhat deeply with the SSA/HHS (helping with medical care for a grandfather), my state's Department of Education (trying to start up an independent school), administrative local law enforcement (obtaining a seller's license for liquor while in college for a job), and several city/town/village councils/boards (planning/permitting local events).

For all my interfaces with the state, my answer to that question is still, "no, I've yet to find a single part of government which doesn't do some or all those things." Hell, even the student government at my university did those things.

Maybe HN commenters describe so many things as regulatory capture or rent-seeking because that's what our world is now.
That's exactly what I was wondering about, and here's the answer. I love HN!

So from the article:

> Black holes [merging] produce gravitational waves but not light.

So really, if you were orbiting such a pair of about-to-merge black holes, the gravitational waves produced by the merger would cause just nm-scale fluctuations?

Also, 1 AU seems awfully close to a pair of orbiting ~25 solar-mass black holes. I skimmed the paper, and didn't see anything about how the orbital distance evolved, leading up to the merger. One could probably calculate that from the mass and spin estimates, it's over my head. So maybe, at 1 AU, the about-to-merge black holes would look effectively like a point mass. Anyone want to venture a guess?
Run. Seriously. Here's why:

You are running a business, or at least trying to. Ruling by consensus doesn't work, eventually. And that's when shit will start hitting the fan.

The work you've done isn't nearly as i.lortant as the work you'll have to do. It's unclear if you have the right skill sets to get to the next level now. And the skill sets you may or may not have, but will need, are worth way more than the nth developer. And if you all don't see why building to support 3 channels first, when you don't have customer validation is a problem, you don't have the right skill sets

If you are all friends now, you won't be soon; no matter what path you choose.

My advice, find someone who has the experience with running early stage startups and figure out what terms they would need to step in. That should give you an idea of a reasonable way to structure the deal.

Some things to note, the CEO is timely responsible and that's worth way more than each incremental dev, in terms of equity.

Profit-sharing is a great idea. But, it doesn't have to be tied to equity per se.

Figure out if you are all serious about turning it I to a start-up or just having fun coding. Then, go from there.
There’s certainly a chance of that happening, but that’s a much more acceptable risk than letting an unrepentant criminal claim another victim.
US government has the farm bill which provides some form of insurance:
https://www.washingtonpost.com/news/wonk/wp/2014/01/28/the-9...

This provides a price insurance for farmers. This year's price was set at: $3.96 per bushel for corn and $10.19 per bushel for soybeans (reference - http://www.wisfarmer.com/story/news/2017/03/08/corn-soybean-...)

So with the support prices, unless the yield prices goes below support, people will still grow corn.

As how does it affect Canada? For one, Canada will surely be having it's own insurance program. Second, It is a simple arbitrage play, if Canadian supply is cheaper people will buy cheap corn from there and import to US.

Curious what price level you would say is unprofitable to grow corn?
Yes, NNS and BNS collisions are very messy. NNS are also very likely to form a BH.

> Will we reasonably ever hear a supermassive BH collision?

Hopefully! They'll certianly be looked for. There are some extremely massive SMBHs out there (e.g. Blazar QSO B0218+357), and it's reasonable to think that at least some of them are the result of mergers of SMBHs rather than, say, a rain of smaller BHs (and dust, gas and stars) onto an already big BH (which may also happen).

In theory as opposed to _unrestrained_ capitalism. As the idea goes, abusive monopolies get out-competed. The logic goes that money will inevitably buy power, so a government of limited purview (but unlimited strength to check market excesses within that purview) is best.

I take your point, though -- that "No True Scotsmen" capitalism, like actual factual communism, is an ideal that has never been achieved, and that incentives will always render it imperfect. It does empirically seem a rather safer ideal to aim for, though.

An important thing about layers, about defense in depth, is that you can’t even begin to attack one mechanism until you’ve defeated its predecessors. DANE + TLS doesn’t give you layers. If I can subvert your DNSSEC, I can endorse a fresh TLS key, and win. If I can subvert your TLS, I win.

This is defense in breadth, a strategy known mostly for its close association with defeat.

In my case most often it’s a hygienist who takes the x-rays, not the dentist. But even assuming it’s the dentist, and the dentist is paid at 200k/y, that translates into $100 per hour or about $1.7 per minute. It never takes more than 10 min to do the x-rays, so the labor cost of a set of x-rays can be at most $20, most likely much lower.

Oh you’re right, I somehow missed that. Well that makes things more interesting doesn’t it.

I guess that leads back to my question (in another comment) about whether or not face paint would effect it.
Wouldn't the CO2 be absorbed over a period of time, which the combustion would do it all at once, being a net positive as far as the environment is concerned?

Or perhaps I don't understand how CO2 harms the environment well.
It was brought to my attention in another comment that they do have an IR light to illuminate the face besides the dots.

Now I’m even more curious about the face paint.
First of all, it’s pretty clear from the whitepaper that the sensor and the Secure Enclave speak over an encrypted channel - you’re not going to be able to inject valid data.

Second, the point of using an IR image (in addition to the depth image) is that a simple 3D print is not going to provide valid spoofing - it will not match the IR absorption profile of a live face. Additionally, they are also likely testing for liveness by looking for changes from image to image, even if it’s just saccades of the eyes.

Third, Apple implies that they are taking a sequence of images. They can, for example, look for changes in IR images associated with blood flow correlated with your heartbeat, which prove you are alive and may be distinguishing from individual to individual. The secure enclave could also request specific changes in the images that can’t be predicted in advance, thus foiling attempts at feeding in canned images.

In short, I don’t think it’s anywhere near as simple as you propose.
