  1. Most developers should do their job faster and with better quality and stop arguing with their Product Managers.

    Well, Devs *should* argue for things that need to be in there, but yes they should also be professional enough to do what is required to make the product available to customers (certified and all). However, a PM also needs to find a way to make everything fit within the guidelines. It may be that a given feature the PM is arguing for breaks something else that is also extremely important. Thereby if the PM doesn't have a development background then they too are dysfunctional and only being a hindrance to the team and product.

    Either way, professionalism goes both way. Work with the team to make the feature some feasible for the product.

    Unattributed -- The repo is named "wix/WordPress-Editor-Android" ... I would call that a pretty explicit case of attribution.

    Wix seems to be in compliance with the GPL. The source for the entire version of their editor is available on GitHub. Matt Mullenweg seems to be aware of this repo and yet he insists that there is some additional and unidentified code that is not publicly available. When one uses terms like "stolen", it is irresponsible to not be explicit about the details.

    The question is if the distributed Wix mobile app linked to the GPL code. If it's linked, then you also need to post the source code to the Wix mobile app.

    Depends on how it is linked - https://en.wikipedia.org/wiki/... - but you could be riding a dangerous line.

    That said, I opened up Wix's GitHub site, did a search for "word" and found 3 repos - 2 were forks, and the third is likely the project in question. Analyzing that third project (licensed under a MIT permissive license) - it's got some Java (Android) and Objective C (iOS) code; and I think you'd be hard pressed to call it linking by any form. Both rely on a third party parser to do the JavaScript interactions (as applicable for each OS) using WordPress JS API names for sake of the parser and interfacing appropriately there. So it's very likely in that gray area of controversy - an area not well covered by the GPL or community norms; and the App store policies don't help matters at all either.

    >Whether the memory space is shared is nothing to do with the legal text of the GPL.

    Actually it absolutely IS what matters - which is EXACTLY why THAT is where the GPL draws the line - because it's where the LAW and Court Precedent has drawn the line. Because once the code shares a memory-space, it becomes part of the same greater whole - and THAT is legally a derivate work. If, at no point, do the two pieces of code combine into one thing - then it's not a derivative work - just two programs which coexist and copyright does not apply to that.

    Shared Objects (*.so) (dynamic linking) on Linux do not necessarily share the *same* memory space when loaded for use by a program - especially with the Automatic Random Address Loading that has been happening of late to increase security . Focusing on memory space is a misnomer that will not get you very far.

    Now, Windows provides an interesting case as it has two types of Dynamic Linking - one which operates identical to the Shared Objects on Linux/Unix, and another that makes a dependency on the associated DLL. The hard dependency on the DLL probably will be triggered more like a Static Link, but it can be quite murky.

    So again, you're left with the questions of: (a) is the library essential for the software to run? (b) can it be replaced without modification? That is, if you didn't have the library at all, would the program still work on its own - possibly in a degraded state? If so, then it's non-essential and not a derivative work. This is how most plug-in style programs function, and thereby a GPL plug-in for a non-GPL-compatible program doesn't affect the main program.

    And if you can replace the library without modifying the program then you are solely dependent upon the API. Some communities are okay with that kind of linking without requiring the same license, some are not.

    Of course, devs are best to make sure any library is LGPL instead of GPL and you get around a lot of things. Very few libraries are solely GPL or AGPL for exactly that reason.

    I'm sure it does. But it also doesn't run on a whole heap of devices you imagine it runs on. Point is. The entire world isn't Linux, and there's a shitload of custom code out there, far more than the GP implied.

    But it sure runs a whole lot more than you think it does. It's pretty much the backbone of the world right now.

    That's not to say custom OSes and code, etc don't come into play - they do; but >5/10 times it'll be Linux; the rest split between QNX, Firmware only systems, VxWorks, Windows Embedded (WinCE/Phone/Embedded/etc - the 10 different brands MS has for the market), IOS (not iOS), and Custom Code. The majority of that you'll also likely find an SSH or Telnet server with BusyBox box behind it.

    And, FYI, almost no one writes their own OS for embedded any more; you typically will only see that in Firmware only systems; everything else uses something that already exists, and Linux is the cheapest solution that it most easily ported or more likely already is ported, so minimal work to get moving and release a product. (Note: In these markets it is the same level of effort for getting a commercial OS like Windows or QNX to work as it is to write any required Linux drivers; so there is no difference in required dev time, but there is in the required license expenditures. Support costs are generally equal too. So all-in-all, Linux does end up being cheaper.)

    False. PocketPC was a desktop clone for small device form factors that sucked so bad it was hilarious. Sure if you wanted Win95/NT4 on a phone it'd have been great...but then, you had to use a stylus to do anything as that was your mouse, and it required a full keyboard. Could it be considered a Smart Phone? Yes, but it absolutely sucked and never really had a very big market share - no where near majority by any means.

    Palm and then RIM won b/c they actually did stuff the user cared about in easy to use manners.

    Google set their eyes specifically on overtaking RIM and Apple came up and offered something compelling that wasn't a stuffy old blackberry clone.

    Yes, Google and Apple aimed at displacing RIM b/c RIM was the de facto standard for anything more than a basic cell phone. If you wanted email, you got a Blackberry. RIM would probably still be a leader in the market if they hadn't screwed up with a highly centralized network design and had a 1 week network outage - which led to a lot of execs getting iPhones and demanding that their IT departments integrate the iPhone so they could use it; both Apple and Google exploited that, though Apple was the clear winner having a superior and flashier product that the Exec's loved.

    The end result is that Apple is the Market Leader for the Smartphone, if you're not doing it Apple's way, you are doing it wrong. Google recognized that and changed Android from knocking off Blackberry to knocking off iOS, Nokia meanwhile kept on trucking out phones that appealed to people who didn't care about smartphones. Microsoft's killed it's own market share in order to push Windows Phone 7, then 8, and now 10. Each time halving their market share. So they went from 11% in 2001 to 0.7%.

    Microsoft screwed up and lost it's foothold in the mobile scene. Had they never dumped the PocketPC, they might be market leaders today.

    Well, if Microsoft hadn't abandoned PocketPC (aka Windows Mobile) then yes they'd probably have a bigger market share, but it'd still be a pittance compared to Apple and Google. As I said, PocketPC was basically the Windows Desktop in a small form factor - it would not be able to compete with Android or iOS. It also didn't have updates of any kind - builds were done by hardware vendors (not Microsoft) and there was no AppStore kind of thing for it. What you got when the device shipped is what it had when you retired it.

    But that was always the Microsoft motive operandi - everything was focused around the Windows Desktop Environment or was an extension of it. For mobile, they put out PocketPC/WindowsMobile to exand Windows Desktop to mobile/small form factors; they put out Windows Server to push Windows Desktop into the Server Room; then extended Windows Desktop into the XBox to capture game consoles; they put out Windows 10 IoT to capture things like RasperryPi's (accessible and programmable only via Visual Studios, no direct user-interface).

    No, Microsoft has not really learned the lesson of the failed Windows Phone experiment - that they won't ever hold the entire market, that people don't want Windows on everything. They're done a bit better with Azure and responding with LInux capabilities on it - but it still runs on top of Windows and all the overhead that incurs.

Stage 3 departs from orbiter and without using any extra fuel could make it's way into the sun - really, the sun has this awesome thing called a gravity well, and all you need to do is get the stage 3 section into that gravity well and the sun will do the rest.
