One of the cleverest features of the rational expectations revolution was the appropriation of the term "rational." Thereby, the opponents of this approach were forced into the defensive position of either being irrational or of modeling others as irrational, neither of which are comfortable positions for most economists.
(Barro 1984)
I suggest that critics instead adopt the attacking position of describing this concept (the capacity to foretell the whole future of the economy) as a dictionary would, as "Prophetic Expectations".
That's the point when I will stop helping someone. When it feels like every time they ask for my help, they don't retain anything. Sure sometimes it's easier to explain some language feature by quickly typing an example. But if I end up writing most of the code to solve your assigned tasks on your keyboard, and you don't seem to be learning anything, why do you work here again?
They could have closed this loop hole by providing a royalty free font showing how the character should be rendered. Without that each platform is *forced* by copyright law to deviate from each other.
Probably just by launching; market://details?id=<package_name>.
If the phone has "unknown sources" turned on, you could save the apk to the sdcard and launch the file url. Perhaps using a content provider to stream the apk directly from your assets folder.
It's a rematerialisable constant. In a tight loop under register pressure, the compiler might choose to keep reloading the value into a register. Shrinking the op code may mean that the code of the entire loop fits into a cache line....
Compiler engineers certainly do think about these things. Even if most developers don't care as much, there's a HPC project somewhere with someone employed to worry about these kinds of problems. Plus it might allow them to get better performance numbers on a specific benchmark.
X (the protocol) isn't really going away. You can run a cut down X server that does all of the decorations and so forth, then draws the window via Wayland. It isn't perfect, it may not appear exactly the same as it used to. In this way X joins VNC & RDP as client applications that can draw windows or desktops on a Wayland compositor.
The main "problem" in this case; Once you create and publish the details of a transaction, there is no way to invalidate it. Even if it hasn't appeared in the block chain for 2 weeks, you cannot assume it will never happen.
The rest of TFA is speculation about the how this transaction *might* have been ignored by the mining cartels in order to defraud someone. By hoping that an attempt would be made to create a second transaction, with different inputs, to make a payment to the same people.
Option 4 is unlikely, they made too many separate changes to enable this backdoor;
1. Use the broken Dual_EC random number generator.
2. Use their own Q constant, not the standard one decodable by the NSA.
3. Send 32 raw bytes from the RNG in a network packet.
4. Add a hard coded ssh password, with the same format as a debug string.
Whoever did this was trying to be underhanded. Leaving few clues in the source code and compiled binary. But there's no way these changes were accidentally included test code.
No, these are not "standard-breaking" errors, as this is how the standard for blueray is written. The blueray disk include interpreter bytecode that can read these memory values, derive decryption keys & decode blocks of video. The rest of the video is encrypted with AACS.
We're talking about a targeted attack that requires local (-ish) access. Firstly you can probably assume the target has a locale appropriate to their location. However that isn't required, as a USB HID device can send raw 16-bit unicode.
That's a hex dump of a PE.exe file. They then type a powershell script to convert it to binary. That's arbitrary code right there. Unless you have gone to unusual lengths to prevent the launching of an.exe.
Don't need to know the keyboard layout. Only need to guess that it's a window's machine that is unlocked. You could also move the mouse or perhaps press the scoll-lock key occasionally to prevent the screen saver from automatically starting.
Unlike most of the other responses that I scanned through at the time, which required a browser exploit, or ftp access. This approach could be used to run arbitrary code without the assistance of a 3rd party server, or a known browser exploit. It only depended on Win+R, cmd, notepad and powershell. And I'm sure that list could be reduced further.
First we define what Avogadro's number is. Based on a measurement of the number of atoms in a silicon sphere of known mass. The ratio between the weight of a single silicon atom and plancks constant is already known, so this would give us a way to convert from plancks constant to a new definition of a kilogram.
Of course, measuring the number of atoms in a silicon sphere is hard to reproduce. Enter the other competing method, the watt balance.
Place an object on a speaker cone, then measure the current required to hold it aloft. Move the speaker cone, measure both the created voltage and the velocity. We can use these measurements of current, voltage, velocity and a measurement of the local acceleration of gravity, to calculate the mass of the object. This is equivalent to measuring the value of an electrical watt in SI units, which allows us to also compare the measured mass to plancks constant.
Oh, right "who didn't buy into". I think I parsed that differently for some reason. I've been following Steve Keen, well before 2007. We got rail-roaded into predicting the timing of a property crash here, but underestimated the lengths Rudd would go to. With China slowing down, we're in for a bumpy ride.
There might be another crash, with a couple of high profile failures. Then we could all gloat and say "I told you so". But we might just see more of the same QE crap to keep the banks afloat while they slowly rot away from the inside. I'm not going to try and call it though.
Australian here, who DIDN'T buy into the ridiculous bubble housing market here
Yes we did. Rudd kept the bubble going during the crisis with his first home owner boost, plus the interest payments got more affordable with the downturn. Just when it looked like it might be popping.
Our debt fueled housing bubble will burst eventually.

No. No they won't.

How about a reimplementation of a Commodore C65?
How many unique English tweets are possible? How long would it take for the population of the world to read them all out loud?
Even with only 140 characters, there are *a lot* of possible English phrases.
And what if you tried to store them all for future reference? You'd end up boiling the world's oceans.

The summary almost had the full feature list anyway. You could have edited all those links into it so you didn't have to repeat yourself.
Yep, it's really not that hard.
They are also trying to block spammers who are trying to bulk harvest email addresses. For that traffic, each request *is* a simple GET.

Sure it's not "news" to many of us, but might still be interesting to some.
If you want bookmark management, use an add on..
Simple bookmark management should be built in. But perhaps even that should be an add on, just one that is installed & enabled by default.
