Re:UntilThe problem is not that C++ has some subset which is safe, but that it everything else is unsafe and neither the compiler, nor your code reviewers are necessarily going to save you. C and C++ suffer bugs that COULD and SHOULD be caught by the compiler but aren't.
You can code review this subset of C++ til you're blue in the face but the next project over to you may not. Even some of the most reviewed and widespread code in existence has suffered serious errors that were the fault of the language. Look at the Heartbleed bug as one example. And it's extremely clear that when we're talking of software that powers IoT devices, or cars, or hydraulic presses in factories, or X-Ray machines or anything else which has a critical function that even ONE screwup could have catastrophic consequences. Even if your software has less critical failure modes, it's still a pain in the ass if it crashes, leaks, suffers mysterious race conditions or is exploitable because the code has to enforce its own buffer checks.
That's why Rust makes such a good fit for systems software. It shuts down an entire swath of potential programming errors before they can even happen. In the normal course of programming there are no pointers, or null pointers, or explicit memory allocation/deallocation. Things like strings and arrays are intrinsic types and are enforced against their length. Threads that share data MUST protect them with locks or mutexes or have ownership. Things that break in C/C++ at runtime are stopped by the compiler.
C and C++ aren't going anywhere I'm sure, but neither are they defensible by saying if you know the exact subset which is safe that it absolves all the stuff which isn't in that subset.

Re:Most of the web really sucks
Um, I think you lost a zero. The speed of light in a vacuum is 299792458 meters per second, so your 300,000 km/s figure is more than close enough. However, in a single mode glass fiber, it's about 2/3 of that, around 200,000 km/s. 3000 km / 200,000 is 15 ms, and the round trip would be a minimum of 30 ms.

Re:Can't think out of the box
Some folks think they're smart by trying to steer the discussion away from what the asker wants to talk about by suggesting that the question is a case of The XY Problem.
Such behaviour is disrespectful to the asker as it asserts that what they're trying to do isn't useful. If somebody wants to manipulate foo files with an unsuitable bar, then the more informative answer would be to:
a) Answer the actual question asked instead of replacing it with something else.
b) Explain why the method the asker is attempting might not be as productive as they believe.
c) Provide the showoff answer so you can feel good.Something like 'It looks like you're trying to manipulate foo with bar, if you want to do that, use bar.exe -slow foo.txt. However be aware that this doesn't scale since it was written in 1996 and doesn't use multithreading. Instead use multithreaded_baz.exe foo.txt and you'll see a 100x speed increase, also this is open-source.'.

Re:And in fact you do the opposite
Be careful with this -- don't forget to UPDATE those physical envelopes when necessary. And that still doesn't solve intentional breakage where someone changes then absconds with the new controlling credentials.
A stored-in-a-safe envelope is still a single point of attack, albeit good for emergencies. If you want to distribute the password and know you have time to recover it, see Shamir's Secret Sharing Scheme or overview for how this would work. Basically: for T total users force a quorum subset Q of them to agree to use the password. A non-quorum won't work but it doesn't take all T users to recover it either. Personally, I'd use Multipar to generate the details.
And that's only good for passwords. It's better if you can create alternate groups and accounts with different rights (least privilege) and farm those out for daily use. At work in MS AD, we mothballed the original "God" Forest account and schema master and used other just-as-good proxies and groups for daily and special admin.
The idea was that way if anybody not in the original group successfully took over the tree/forest (or we managed to shoot ourselves in the foot!), there was one "hidden" unused account that still had overriding rights over everything that could be used for recovery. Also, "Administrator" was a false ID -- it didn't do anything and had auditing turned on for any failed attempts. No one used it, so if someone TRIED: something is definitively wrong. -

If you need that program and it's so special or difficult that nobody has tried to write it yet, you'll have to pay for people's time. There are a number of code bounty sites. From a quick web search: coderbounty, sourceforge:helpwanted, bountysource, freedomsponsors and other alternatives. I haven't used any of them, so no idea how much publicity they get you.
Maybe you get more exposure if you offer a bounty on Stackexchange. Even if nobody accepts the coding challenge, you may get valuable advice in the answers.
Of course monetary incentives for creative work will fail if there's no intrinsic motivation (see Dan Pink, "Drive"). But funding can give a coder the time needed to attack a problem they find interesting.

Re:Lineage OS
So we will have Android distros from now on?
We long have had. See XDA-developers. Some minor distributions support multiple devices. Then there's AOSP-based distributions which are much of a sameness, though with different launchers and baked-in apps. There used to be AOKP and SOKP, the Android Open Kang Project (and Sonic...) but they both seem to have gone away. Now there are many lesser AOSP derivatives. And then, of course, CyanogenMod, which is now going to be Lineage.
I miss SOKP, it's what I was running on my Moto G 2016 (Titan) but then basketbuild asplode and then there was no more SOKP. So now I have the last nightly of CM14 on, and it's working well.

Uh
Another said that Windows 10's spyware aspects made him give up on his beloved PC platform and that he will use Linux and Android devices only from now on
Sounds like someone is in for a rude awakening about Android. (I think Win10 is worse than stock Android re:data collection, but if your primary concern is privacy...)
As to the question itself: It absolutely is, for varying definitions of "cool" and "fun". I'm a 90s kid (so many things I have to remember) so I didn't cut my teeth on a C64, but as a youngling I got sucked in by the potential of PCs and what I could do with them after discovering epic tools like "dir" at 12. (Oh, and playing Zork.) There's still a tremendous amount of potential, but a lot of us have turned what were once hobbies into jobs and started specializing in a sub-aspect of computing. The former can easily deprive the "cool" of the hobby if your job is a negative aspect of your life (and thus whatever "computing" you do is associated with that negativity), and the latter limits the "fun" because the simple problems are mostly rote at this point and discovery means chasing the long-tail, if at all.
In my case, a major lure for general computing—that made it "cool" or "fun"—was that discovery. While I've lost my own wonder and interest (for varying reasons), there seems to be as much uncharted territory now as there was in the 80s/90s: augmented/virtual reality, Internet-of-Things, alternative inputs (particularly in motion controls and applied to VR), biomedical, brain interface (both direct and indirect, such as simple headgear that react to brain waves). Computers are far cheaper and more powerful than they were, with software that can allow Joe American to start basic 3D modelling with something he picks up at Best Buy.
Computing itself isn't necessarily static: I think we're going to see computers in general converge, where either your phone/tablet is also your main PC, which, when docked, has more processing power (Nintendo's upcoming Switch is reported to work this way, in fact) or "always-on"+"cloud" means your various devices are just UI for data on the internet. Regardless of which direction you prefer, either will be enough of a shift to provide tons of creation/discovery potential driven by demand.
A point of general agreement was that big tech companies in particular don't treat computer users with enough respect anymore.
A bunch of assholes deciding against consumer interests (and then consumers rewarding them for such) doesn't deprive computing of being "cool" or "fun"; it just means you may have to seek alternative platforms depending on the aspects of computing that drive you and how you want to enjoy that.

Re:Patentee needs to be shot in the head.
This is not a novel invention. This is trivially obvious from hitting the problem 'I am deploying lots of drones'. All of the above solutions are obvious and un-novel and in no way not obvious from prior art.
Prove it, then. If it's not novel, you should be able to find someone doing it before November 2014. Otherwise, by definition, it's novel.
And if it's not obvious, then you should be able to find all of the elements of the claim in one or more pieces of prior art from before November 2014. I'll help. Here's Claim 1:1. A method of operating an uncrewed autonomous vehicle (“UAV”) comprising:
establishing, at the UAV via a communication interface, communication with a mesh network comprising a plurality of other UAVs;
generating first location data of the UAV using a first navigation system onboard the UAV, wherein the first location data indicates a first location of the UAV;
receiving external data from one or more of the plurality of other UAVs in the mesh network;
generating second location data using a second navigation system, wherein the second location data indicates a second location of the UAV;
determining that the first location data differs from the second location data by a threshold value;
determining operation of the UAV is compromised based at least in part on the external data;
transitioning to a fail-safe mode wherein the UAV is configured to disregard one or more of commands, the first location data, or the second location data; and
transmitting alert data indicative of: the compromise of the UAV; and last available location data of the UAV.Now, establishing mesh networks and receiving data over mesh networks has been done since at least 2007, according to Wiki.
Here's a post from April 2014 on redundancy in airplane autopilot location guidance, so there's generating first location data and second location data, but it doesn't mention the threshold comparison, and states that the transitioning is manual with only two computers. So that doesn't help.It's very easy to say that something is trivial in hindsight, but that's like saying that someone "looks" guilty. It's a lot more difficult to prove it with evidence, and that's what's required, legally.

Re:Confirmed Existence?
What's a "placeholder"? There's a lot of things we can't observe directly. By this line of reasoning, quarks and gluons are definitely "placeholders", since we're never going to observe an isolated quark or gluon.
A place holder. A placeholder is just that. They have been in use since we've done science, and are critical to advancing science. It's kind of like the old "Strange and mysterious are the ways of God" that bible people use when backed into a corner, but with one critical difference.
The bible people use their term as a way of squelching further argument or discussion. Science placeholders are used as noting that there is "something going on here that we don't understand" or know what it is, but instead of folding the tents and saying strange and mysterious are the ways of the universe, and stopping further research, the placeholder acknowledges the anomaly, and allows further research, and often the further research clarifies just what the placeholder is.
Observing directly is not a requirement for confirmation or denial of a placeholder. http://physics.stackexchange.c... has a pretty good explanation. "Quarks" were indeed placeholders when first proposed in the mid 1960's. Further experiments have exposed things that act just like quarks were predicted to act. https://en.wikipedia.org/wiki/... warning - headache inducing stuff.

Re:At least iOS is still around.
They're literally the same thing. Apple's "secure enclave" uses the ARM A7's TrustZone/SecurCore tech, which is basically an independent CPU in the same die. There's nothing magical about it - Android's been supporting it for eons now: https://source.android.com/sec...
Sorry, still incorrect. Although Android is (gradually) getting better, slowly, it still is hit and miss, depending on which SoC your device OEM decides to use.
The only thing I was incorrect about is that I was under the impression that the SE was a separate component, rather than being implemented on-die in the Axx SoC. Other than that, my assertion that iOS' Security is more robust than Android's, stands.

It's Hiya, and I don't like its lack of privacy
This is merely a rebranded version of Hiya, which still requires surrendering your entire contact list and conversation metadata to a third party without any masking.
Then again, even if each phone number was stored as a PBKDF2 hash, since there are only 3-4 billion legal phone numbers in the NANPA numbering system (given 370 area codes). I estimate this would take under 45 minutes on a quad-GPU system (divide by the number of nodes in your cluster). I suppose this is a decent hurdle, but not quite good enough to make me happy. Maybe the solution would be to also include the victim's area code's primary state in the hash (which would then require 12-36 hours to break), but then you'd have limited utility when dealing with interstate regions like the DC Metro area or the Tri-State Area.
Security and privacy often butt heads, but I think that the right design can facilitate the right balance. The same goes with security vs freedom (we all know the Ben Franklin quote, right? "Those who sacrifice liberty for security deserve neither"). None of these are opposites.
I'd feel a lot better if Hiya had a regular transparency report, but I can't find such a thing.

Re:Oh well...
Coming to terms with who you actually are is a sign of maturity.
You can use the same argument for depressed people. We all went through it as teenagers, but if you're depressed as an adult, clearly you never matured. I'm not going to pretend to be able to fully comprehend the force of why, and clearly neither can you - but we also don't have the condition, and much like an addiction to drugs, I'm pretty sure neither of us will ever fully understand the force behind it unless we actually became drug addicts ourselves. I daresay that if it matters enough to them that they're willing to undergo the extensive and sometimes absurdly difficult tests and procedures to change, and they report a high increase in happiness afterwards, I think there must be more to it than merely a phase - and it would probably be wise to remember that not everybody lives in your shoes...

Re:America hates Hillary Clinton
which adopted the idiotic winner take all formula, which pretty much completely undermined the original intent of the Electoral College
The "original intent" of the Electoral College was to give slave states a way to count their slaves toward their representation in the POTUS election, without having to do anything crazy like actually allow those slaves to vote. The southern states wouldn't agree to a Constitution that called for a straight vote, because their plantation-societies would have been heavily outvoted every election, and there would never be a slaveholder POTUS.
With the EC and the 3/5th compromise in place, 4 of the first 5 Presidents were owners of slave plantations.
Protecting slavery is what the EC was created for. All other reasons for it you may have heard are just a big steaming pile of marketing.

Re: Genuine question
Except that electors in the past have cast votes against the candidate they were supposed to support, and in this particular election one of the parties doesn't really like it's candidate anyway. Apparently three republican electors have pledged not to vote for Trump.
Faithless electors are almost always protest votes. In other words, you'll only see one if their vote won't change the result.
The only time an elector has ever voted for the other major party candidate was in 1796, and the only time it happened when the electors in question thought they were going to change the result by doing it was 1800. The rules (Constitution) were changed after that. Using electors to overturn the election result just will not happen.
I don't like it either, but I've been a Democrat a long time, and this is not my first loss to have to live through, and it likely won't be my last. Sometimes, even if you are 100% right, you have to be in the opposition for a term or two. Its healthy for the country in the long-run.

4425*850=4 million pounds of satellite
That is an enormous amount of weight to send up. Space-x is aiming for (has not achieved) $1,000 per pound. Their current cost is more realistically $4,000.
4425*850*4000=$150,450,000,000. Then add the cost to send up another 4427/7=630 satellites per year (630*850*2000(because they'll get costs way down if they can send up that much material)=$1 billion dollars per year. They need to spend 150 billion dollars initially and an ongoing 1 billion dollars per year.
In 2014 SpaceX had a "market cap" of (optimistically) 12 billion dollars. Let's assumt that 12 billion dollars have already been justified. Now rumors of an IPO have been heard, so let's assume a massive over-the-top IPO: 13 billion dollars. Then add in a billion dollars. (assuming every penny they can scrape together goes to this plan) 12+13+1=26 billion. Using realistic numbers for launch costs and hyper-optimistic numbers for funding, they're about 125 billion dollars short. And I don't see Trump signing a 125 billion dollar Space-X pork bill. If we're very optimistic about launch costs that hypothetical bill could go as low as a still-highly-unlikely 75 billion dollars. -

Re: Sonic Boom
This article claims it was 110db at take off. Loud yes. But that has nothing to do with the volume at ground level while the plane flies at Mach 2.2 at 55k feet.
Can anyone dig up a reference for an actual sound reading taken while Concorde over-flies at max speed and max elevation?
There is also this, which starts out very promising and I got excited that it may actually answer the damn question. But it doesn't. The guy claims that the sonic boom is equivalent to a loud trumpet at 0.5m, which may be true, but makes no correction for the fact the concord is 55k feet away.
Some more info here, but still nothing definitive.
The problem is all the reference points don't apply, since the main comments are from those observing the space shuttle (Mach 25 vs Mach 2.2) and military jets at much lower altitude, i.e. performing maneuvers. What we really need is a sea captain's report from the middle of the Atlantic.

Re:Just curious...
1) It's already being done. Commonly.
2) Something closer to this. The one you linked produces 128W continuously, plus 2KW of thermal energy. On that kind of power you could run continuous communication with Earth, not just bursts for a couple seconds per day.
3) The probes being small, can be considerably accelerated - rocket equation works in both directions; tiny dry mass can afford a lot of extra delta-V. And you could use colloid thrusters or other similar extreme-ISp ion microthrusters to accelerate them a lot over long time using the RTG energy before it's needed to power the radio.
4) I'm not willing to ballpark the number of the probes, because that number is precisely dependent on precision of ground stations to determine their position. Suffice to say Jupiter definitely exerts clearly detectable influence on probes in LEO - not something on the margin of detection threshold but actual clear readouts. So your ballpark (0.06AU) is way off. Consider each probe covering a "corridor" of 10AU radius a more likely figure and a rather conservative estimate.

2) Anti-glare LCD panels
They have been since forever. My 15" from 2013 has anti-glare stuff on the screen.
3) Ports (you know, things like USB 2.0/3.0, Ethernet, headphone/microphone jacks, DisplayPort, etc)
It has four ports that are any of those things you want plus more, with a very high rate of transfer.
4) More than 16GB of RAM
:Not impossible you know. It will just cost a lot more. Since the OS is less bloated than Windows and uses memory compression tech now, it's sort of like having a 32GB Windows laptop though...5) User replaceable batteries, OR a built-in battery of sufficient capacity this doesn't matter
It's (b) already. If you must replace it (though why you would, I don't know, I've not had to in three years of service from my current laptop) you can do that yourself with some effort, or just take it to any Apple store and have them do it on-site for a small fee.
6) Keyboards with a reasonable amount of key travel (0.5mm or whatever it is on the nMBP is hardly sufficient)
This is frankly a stupid ask, it's not the travel (at least not all), it's how the keyboard feels to use.
7) Apparently, I can add "keyboards with a reasonable amount of physical keys" to this list as well

Okay, what's the minimum delta-v required to pull that off?
The best answer I could find (without a ton of effort, honestly) is this. I have no idea how the calculation is done, so I can't comment on the accuracy, but the claim is that a bi-elliptic transfer could potentially do it in between 3000-8000 m/s (from LEO). Take that for what it's worth.

Still supports Right-Click "Run Anyway"; so quitchetbitchin'. This is actually MUCH safer for ALL Users, while still allowing Power Users to do what they need to.

"Allow apps" from only "sanctioned" sources now
I see in System Preferences, Security & Privacy, General, that Apple no longer thinks you have the right to run downloaded programs.
The "( ) Anywhere" option has been completely hidden.
Allow apps downloaded from
( ) Mac App Store
( ) Mac App Store and identified developers
( ) Anywhere <-- Now hidden!?WTF !

Re:UmIs the problem of cheap blue LEDs News worthy? The conversation certainly is. News can inform but need not always be just current events, particularly on the Internet where nothing is paper.
Slashdot is a news aggregation site. Ostensibly for 'News for nerds, stuff that matters' at founding. In practice is was a blog for Rob Malda, CmdrTaco. It was also a website with an accidentally really good commenting technology.
Been around long enough to see the jokes about not reading the article? Then you have probably been around long enough to see the argument that a lot of the people still visiting the site do so for the conversation in the articles. They provide everything from group-think arguments, good counter-arguments and funny jokes about the topic to warnings about click-bait, pay-wall free options and corrected sources.
If Slashdot had ever depended upon the quality of the articles it would have failed when it was still Chips-n-Dips hosted on a university student account. The commenting system is more than a chance to keep up your HTML skillz. People in the know are really providing the value. (Queue complaints about Facebook's model, etc.) However, getting quality articles is important to attracting the readership that does not know about the site.
For instance, this article currently doesn't shows up in Google search for annoying LEDs, being a day old. But the top link is for lifehacks.stackexchange.com for whatever reason. Stackechange and Amazon dominate the front page. I almost feel sorry for companies with products on that page. Even with no such thing as bad marketing, being known for having annoying lights on your non-party-joke product is not a good thing.
The Blue LED backlash article on McConnell's blog is page three. And he discusses a vendor that sells low intensity LEDs for computer products. But I expect - or at least hope - this slashdot article to make it to at least page three with McConnell's blog if not higher.
