No, they certainly would mind, because this is something that would cause an uproar among the general population, and that would directly affect their sales, besides bringing lawsuits and very bad press.

This is why corporations care about user security at all. They care only because they want us to buy their products. It's really important to keep the profit motive in mind when talking about corporations. Most aren't inherently evil, but neither are they altruistic. They essentially neutral, wanting only to do business with us, so you can expect them to typically act in their own best interest. This occasionally coincides with their customers' interest, simply because it's good business to treat your customers well, especially in a competitive market.

DVD security was fundamentally flawed and could never work, because there was no way to keep the decryption key secret. Modern cryptography with well-vetted standards is currently (and for the foreseeable future) unbreakable if:

a) you choose a strong key
b) you keep the key secret, and
b) you implement the encryption algorithms correctly and securely

Tech companies, especially phone providers, have a lot more experience doing this than a decade ago. Is it easy to do? No, but it's not nearly as hard as it used to be either.

Hah, tell that to my cat! I was having a problem with mice, and wasn't getting good results with traps, so I adopted her from the local shelter. Now, in return for the cost of a bag of cat food every few months, she's kept the house and yard rodent-free for the last 12 years or so.

D sounds like a neat language that I'll probably never be able to use. I'm a game developer, and C++ has a native compiler for every machine I would ever need my code to run on, as well as an already mature ecosystem (engines, code libraries, sample code, all in C++). In fact, C/C++ is pretty much the only option I have if I want my code to be broadly portable.

It's interesting how a lot of languages don't seem worry too much about backward compatibility, because they want to focus on a clean and better language. Unfortunately, in the real world, there are always massive amounts of legacy code that need to continue to work alongside whatever new whizbang features are introduced, even at the expense of a cleaner or more elegant language.

If I had to give any one reason for C++'s success, it would be the standards committee's stubborn (and in hindsight, wise) refusal to "clean up" the language by removing crufty features and syntax, a lot of which were leftover from C. C++ code from 20 years ago still compiles today mostly unchanged, and that's incredibly important when trying to build up or maintain a large ecosystem. You can see what a huge split it causes in the community when a language breaks compatibility like Python did (2.x vs 3.x), and ultimately, I wonder if it's more damaging than C++'s more conservative approach. As a developer, I'd be hesitant to heavily invest in a language that is more likely to break compatibility and leave me stranded.

I ran into an issue not too long ago with a custom stateless unique_ptr deleter, when one of the interfaces I derived from (in a third party library) was placed ahead of my own interface class in the derived class declaration. My own interface had a virtual destructor, while the library interface did not (which I didn't notice at the time). The deleter was blowing up, and only after I noticed it was off by one was I able to figure out why it was happening: the code was unable to cast properly, so ended up at the wrong address in memory because of the v-table layout.

This was fixed by switching the order of the two interfaces which corrected the in-memory layout so it would work. Alternatively, a shared_ptr would have worked as well, albeit with unnecessary extra overhead in that case. It's not exactly a new gotcha, but the unique_ptr + deleter put enough of a new wrinkle on it to throw me off for a while.

C++ gives you a lot of power and speed, but it definitely comes at a price in terms of issues like this. No one who knows C++ would seriously claim the language doesn't have sharp edges that still trip up full-time professional C++ programmers. Still, I love the power and speed the language gives me, while still affording me protection from the sort of mistakes that crop up in C code. For me, C++11 has been an amazing win so far in terms of overall productivity and code safety.

From someone in the trenches using C++, I can definitely tell you that C++ 11/14 has made a massive difference, along with the adoption of better programming practices that have occasionally been eschewed by game programmers because of speed concerns. I describe the new C++ as feeling like C#, except with far uglier syntax. It's fantastic to be able to almost completely eschew the use of raw pointers (at least ones which I have to use to manage memory). It almost feels like the language has garbage collection, except that RAII + smart pointers work wonderfully on resources as well as memory.

I've been working in what is essentially a version of C++ 98-compatible style for nearly my entire programming career. Modern hardware has really reached a point where game developers can effectively take advantage of some of the real advantages of modern C++. It's remarkable how much more productive you can be when you're not worrying about having to carefully manage memory, tracking down a ref-counted leak, or (worst of all) spending hours or even days searching for some memory stomp.

Best of all, a some of the newer features don't even require a significant amount of overhead, but really just put more work on the compiler instead of the programmer. And there are ways to mitigate some of the downsides of ubiquitous RAII-type design (the cost of creating lots of small object), though custom memory managers optimized for those sorts of scenarios.

I have to say, I agree with Bjarne's answers, especially his answer to the notion of dropping compatibility with older features. While it does make the language more complex to keep that cruft around, it's equally important to allow programmers to wrap up older libraries with newer interfaces, for example, and make sure the codebase still compiles cleanly. Since I started out on my own just a year and a half ago, I had the advantage of starting my game codebase from scratch, so I could use the most modern techniques, but I've worked at places with 10 to 15 year old codebases. There's just no way all of that is going to get rewritten in the near future, so backward compatibility is hugely important for the C++ community.

Overall, C++ gets a lot of grief for it's ugly syntax and nasty gotchas, but modern techniques have really eliminated a huge percentage of those. Personally, I tend to view C++ like an extremely sharp kitchen knife. It can be a dangerous tool for novices, and you certainly don't want to use it when a butter knife will do, but there are some jobs that simply demand it.

Hell, Windows is significantly different than Windows from one version to another. That's not why Linux fails on the desktop.

Linux for servers has a significant advantage when serving up internet-related traffic. The job it needs to do is largely platform-agnostic, because it's working with open standards. Given that it can do the exact same job that MS servers can for zero cost, suddenly it has a real advantage and no real downsides.

However, the desktop is a different story. It's not about the OS so much as the software. Linux has a lot of free software that's pretty good. Some of it is as good as their counterparts on Windows. In my experience, though, most are a far cry from what you can find on Windows. And worse, there are a lot of programs for which there are simply no comparable Linux products at all. The desktop is still about what sort of programs you can run locally, and Windows still completely dominates here.

Of course, like you mentioned, Microsoft did it's absolute damnedest to throw that away by inventing a brand new ecosystem incompatible with their old "legacy" desktop platform. They seem to be backpedaling enough that Windows 9 will probably be a decent OS, but we'll see. I'm just waiting for them to lose their square-blocked, flat shaded, primary colored, butt-fugly UI fetish.

I believe those articles demonstrate several things, but it's impossible to tell in what proportions:

* Educational indoctrination from birth, censorship, and propaganda seem to be effective
* Some are afraid to say what they really think, especially when being quoted on the record
* Some don't mind authoritarian regimes or censorship

It's important not to draw conclusions solely from what people say when there are obvious external factors which may be influencing the truthfulness of their statements. The poll data linked in the second article indicated the information was gathered from phone calls and in-person interviews, which means the people responding could not be certain their opinions weren't being tracked or monitored in some way. If you can get in trouble for criticizing the government, and then poll people to see if they have any criticisms of the government, are you surprised when they tell you they have no real complaints?

That makes a lot more sense. I couldn't even imagine how load times could be 45 minutes. Those are build times, not load times.

Still, that wasn't their only complaint. Whatever their technical merits, the team ended up unhappy with Unity, and seemed much more happy with Unreal, apparently. In the end, we'll probably find out if the real problem was the tools or the developers who couldn't use them properly when we see the final game - the proof of the pudding, if you will.

If you read the article, the $500 fee isn't really the primary issue. It's only particularly galling because it appears that the fee is used to license a product that's more or less a workaround for an abysmally poor-performing editor. That fee is in *addition* to everything else, if I understand correctly. I mean, 45-minutes to load a project? Are you kidding me? How do you even manage that on modern hardware? There's nothing more frustrating than a clunky workflow or limited tools that you have no way of fixing yourself. That really seemed to be the driving factor in the switch.

I've worked on large games before (200+ developers). We used our own custom engine and tools, and our designers could start up the game editor and be working in about half a minute or so. It's not impossible to keep things nice and snappy for the end users, even with *massive* amounts of content. You just have to be a bit clever about things.

I think that's a potential problem with a company that does nothing but write engines for others to use. They don't have to actually talk to the people that are suffering because of poor decisions they made, or crappy limitations that they never bothered to address. It makes a big difference when you can walk down the hall and watch people at work using the tools you made. There's a pretty big difference between a fully featured game and little tech demos or samples.

Damn, I still can't get over that 45-minute+ load time. There would be blood flowing in the isles if we made our designers go through that, and rightly so.

Comment: Re:While Buying Back $1.5 Billion In Stock (Score 1) 206

Someone who buys a product with others' tax money is still a drain on the economy, because not only was there a loss of revenue from an actual worker / producer used to buy that product, there was also overhead in the transfer of that revenue. It can no more be a net benefit back to the economy than a perpetual motion machine can sustain its own energy.

Whether or not you feel someone is "working" or not, if their capital is invested, that money is then being used to move the economy forward. Business borrow money in order to expand product lines or upgrade equipment. Individuals borrow money to purchase a car or a home. However, it's dependent on people having capital to invest. In other words, even if someone isn't working, their money probably is. And make no mistake, there's not enough wealth at the top to pay for the government's current spending levels. We could tax the top 10% at 100% rates and it wouldn't even fix our current deficit.

It's unwise to base fiscal policy on emotions such as jealousy towards wealthy people or a desire for social justice. Blaming the rich for not paying their fair share make for great politics but poor fiscal policy.
