  1. Re:Subject bait on A Skeptical View of Israel's Iron Dome Rocket Defense System · · Score: -1

    Of the two hundred or so rockets shot at my city in the past week, we had our first casualty yesterday: an 80 year old woman was injured when a rocket fell outside her house. So far as I know (by hearing the different booms of both successful hits and Iron Dome intercepts) this was only the fourth or fifth rocket to get past the Iron Dome into the city. I'll ask my daughters tomorrow morning: they are the ones keeping score of the booms that they hear.

    You're post was interesting but had so many unfounded logical leaps that the conclusion about Iron Dome effectiveness doesn't follow. I'd be fascinated if you could reply, including your daughters' tallies, but with a precise accounting...

    (1) Out of two hundred or so rockets shot "at" your city, how many were on a trajectory that they'd actually have landed "in" your city? Not many because they're so wildly inaccurate? Or most because your city is large?

    (2) You mentioned 200 hundred rockets shot at your city. Is this the sum of the tallies of "two different kinds of boom" you mentioned, or does the number come from a different source?

    (3) Is the low casualty rate better explained by a high intercept rate by Iron Dome? Or by the inaccuracy of the rockets coupled with the fact that statistically a high proportion of possible landing targets wouldn't hurt someone? Or by the fact that so many people in your city sensibly seek shelter? Or by the fact that the rockets are fairly rudimentary and don't pack much explosive and are unlikely to do damage unless they randomly score a hit almost on top of someone? I suspect that the other factors are dominant and the low casualty rate is therefore not a good guide to the effectiveness of Iron Dome.

    (4) If by sound you distinguish an IronDome hit from a rocket that hits the ground, do you assume that all "ground" hits land in your city?

    (5) In your tallies, you said you heard 4-5 rockets hit the ground. How many did you hear intercepted by Iron Dome?

    (6) Do you think the range of your hearing hit-the-ground and hit-by-IronDome are equivalent?

    The point is a free service being abused is expected. It is not as if noip encouraged abuse and were paid by abusers.

    Expected: That the owners of no-ip should continue to make their own profits from advertising revenue, and a bunch of legitimate users should continue to get free dyndns service, and the benefit to these two groups comes at the expense of a wider pool of internet users who suffer from malware (and at the expense of unpaid volunteers to police no-ip since they're not spending enough resources to do it effectively themselves).

    Does that sound like a fair trade to you? Not to me. Count me out.

  3. Re:No-ip isn't shady on Tired of Playing Cyber Cop, Microsoft Looks For Partners In Crime Fighting · · Score: -1, Troll

    I think No-ip sound very shady...

    April 2013: the OpenDNS blog reported that no-ip was the second most popular dynamic-DNS site for malicious software. http://labs.opendns.com/2013/0... -- No-IP responded that they have a very strict abuse "policy", and they want other people to help by reporting violations of the TOS to them. They also scan daily and filter by keyword. http://labs.opendns.com/2013/0...

    February 2014, the Cisco blog reported that no-ip had risen to be the worst offender: http://blogs.cisco.com/securit... -- No-ip again responded that they have a strict abuse policy, and they want other people to report violations of the TOS to them, and they scan daily and filter by keyword. http://www.noip.com/blog/2014/...

    Were no-ip doing a good enough job at policing themselves? It doesn't sound like it to me, not at all. It sounds like they have a decent "policy" but don't go out of their way to enforce it, their daily manual scans aren't up to what's needed, their keyword filters are easily bypassed. They can sound hurt all they want that OpenDNS and Cisco and Microsoft wrote public blogs or took action rather than reporting the individual offenders to No-IP first. But the fact that No-IP does so badly, and got worse, shows they weren't taking adequate action themselves.

    You say they're "very responsive" to reports of abuse. But honestly, if their strategy for combating abuse rests SO HEAVILY upon volunteers to report abuse, and their strategy hasn't been working so far, then they have a bad business model.

  7. Re:Good bye source compatibility on Apple Announces New Programming Language Called Swift · · Score: 4, Informative

    Are you sure about the "metro"? Name is dead, but I was under impression that all new windows "apps" had to be written in C# against a new SDK that has neither binary nor source compatibility with Win32/posix/C/C++. I'd be glad to be wrong

    You're wrong! You can write Windows Store apps in C++ just fine. This C++ can use win32, posix, STL etc just fine. (however, all apps run in a sandbox, so some win32/posix functions aren't as powerful as normal, e.g. the sandbox doesn't let a Windows Store app enumerate files on the hard disk outside of the files it's allowed to touch).

    You can also write Windows Phone apps in the same C++. So a mobile app developer could write their core in posix platform-neutral C++, and have it portable across Android+iOS+Windows. I know a few who do.

    Of course posix doesn't have anything to do with windowing systems or touch, and win32 APIs (e.g. gdi32.dll, user32.dll) don't apply to windows store or phone apps since they don't have GDI or the traditional windowing system. So your C++ code will invoke new WinRT APIs to access the new functionalities. WinRT is perfectly compatible with posix/win32 APIs. Indeed, for some functionality (e.g. audio), you're REQUIRED to use win32 APIs because they're not exposed in WinRT.

    Here's some example code that shows how you'd mix the new WinRT APIs to get hold of sandbox-specific stuff, and then interop with traditional posix APIs. It also shows how the asynchronous nature of WinRT APIs combine with the synchronous traditional posix APIs:

            auto f1 = Windows::ApplicationModel::Package::Current->InstalledLocation;
            create_task(f1->GetFolderAsync("Assets")).then([this](StorageFolder ^f2)
            {
                    create_task(f2->GetFileAsync("Logo.scale-100.png")).then([this](StorageFile ^f3)
                    {
                            auto path = f3->Path;
                            FILE *f = _wfopen(path->Data, L"r");
                            byte buf[100];
                            fread(buf, 1, 100, f);

    "What exactly are they trying to patent?" -- it says so right there in the first claim, and it's stupid that you spent more time looking up prior art of what you *ASSUMED* the patent was about, rather than actually reading the patent.
