> 7. The Apple troubleshooting guides are out of date. They do not note that if you have a firmware password on a T2 Mac, you cannot reset PRAM as expected and therefore cannot resolve screen brightness issues this way. You also cannot run diagnostics due to the black screen.
I've seen at least one, but it's proprietary and internal to my bigco. I'm willing to bet there's quite a few more at other bigcos. So lucky for you if you can avoid them, but I'm pretty sure there's many of us who don't get that choice.
I do this often, too. Just FYI: all you need to do is tell WhatsApp "Never mind, I'm not actually changing my number" when prompted (which should only happen once per SIM card change). That's it. You'll continue being identified to your WhatsApp contacts by your "home" phone number (not your temporary one).
Car. Nightstand. Kitchen counter while you cook/wash dishes. There's a myriad situations where you want to use your device hands-free. In fact, it's the driver behind an entire new product category (see Amazon Echo, Google Home, etc.).
I'm sorry, but this line of argument is not even wrong as it relates to the entire modern infosec field, which is founded on the fact that there is no such thing as "100% security"; that is why concepts such as "threat models" and "defense in depth" exist.
Also, proving a program "correct" (for some definition of correctness that presumably includes "secure") is undecidable, ergo there cannot be such a thing as a "100% secure language". No, not even Erlang, nor Haskell, nor anything which is remotely close to Turing-complete. So all we can do is, in fact, decrease the attack surface.
That is indeed what the post you're replying to meant. Note that the pointed-to value is a constant string, yet the pointer itself is being modified. That's a fairly common idiom in C string-handling code, only possible because it's a const char , not a const char const.
> No one has ever found an efficient algorithm for an NP-complete problem, and most computer scientists believe no one ever will.
I find these kinds of assertions somewhat misleading. There _are_ "efficient" algorithms for, one could say, "pragmatic variations" of NP-complete problems. Some only work on some subset of cases (perhaps most of the useful ones), or non-deterministic (but you run them enough times and get the right answer), etc.
They don't break it down per-product, but the whole segment was $9.1B revenue out of $20.4B for the quarter. And the only hint we get about this product specifically is:
"Devices revenue decreased $1.8 billion or 49%, mainly due to lower revenue from phones, driven by the shift in strategy for the phone business, as well as lower Surface revenue. Phones revenue decreased $1.5 billion or 58%, as we sold 5.8 million Lumia phones and 25.5 million other non-Lumia phones in the first quarter of fiscal year 2016, compared with 9.3 million and 42.9 million sold, respectively, in the prior year. Surface revenue decreased $236 million or 26%, primarily driven by the release of Surface Pro 3 in June 2014."
In fact, I believe they are doing exactly this in El Capitan. Under the umbrella of "Rootless", you will no longer be able to arbitrarily modify [1] some special blessed OS processes, like Finder.app.
I came in here to make exactly your points 2 and 3. They cannot be overstated: they haven't even gotten the budget math to work out yet.
Given unlimited resources, sure, who wouldn't want free universities. But making it work within our real-life constraints means something else is going to suffer for that, and in today's reality it's going to be really hard to make the case that this is a priority. (Especially when many high school graduates are still basically illiterate, so only elite graduates will make it in, which means we'll be further subsidizing the elite).
This reminds me of the people who, at the dawn of the smartphone age, were proudly boasting of their dumbphone's week-long battery life vs. the nightly recharging required by smartphones.
Until they realized they were completely missing the point, since they were comparing a phone to _a pocket computer with a constant data connection_. Most have since stopped boasting and just silently plug in their phone every night.
