Many laptops have a battery preservation mode which avoids full recharges. Long term storage (or worse, usage) at 100% capacity is damaging to a lithium ion battery, so limiting charge capacity to (e.g.) 50% the lifetime can be dramatically extended. It helps in any case, but it's particularly useful if your laptop is usually plugged in. Unfortunately, this feature is often hidden away somewhere, or requires an extra download - almost nobody uses it, which is a shame.

I've got a similar rig, but I'm using the seasonic 400W platinum power supply. It's similarly priced, but it's entirely fanless, and more efficient at typical loads. With just the iGPU, the machine - overclocked and overvolted - still only uses around 20W, which is just next to nothing. At full load it's not much over 100W, and you need to load the GPU and use AVX to even get it to 100W. It's enough for even fairly high end single card GFX builds, and, of course, it's silent.

I use the thermaltake HR22 CPU cooler, which is also fanless (If you want high overclocks, you can always add a fan).

Oh and one minor detail: did you see the final compiled code sizes and how much smaller the optimized versions are (esp. clang!). I'm willing to bet the entire benchmark just code "optimized away" by dead code elimination; and that's an entirely unrealistic situation... Also, where's the code? Is this reproducible?

The benchmark isn't worth anything.

Nerval's Lobster writes "In a previous posting, developer and programmer Jeff Cogswell compared a few C++ compilers on Linux. Now he's going to perform a similar set of tests for Windows. "Like all things Windows, it can get costly doing C++ development in this environment," he writes. "However, there are a couple notable exceptions" such as free and open-source cygwin, mingW, Express Versions of Visual Studio, and Embacadero. He also matched up the Intel C++ Compiler, Microsoft C++ Compiler, and the Embarcadero C++ 6.70 Compiler. He found some interesting things — for example, Intel's compiler is pretty fast, but its annoying habit of occasionally "calling home" to check licensing information kept throwing off the rests. Read on to see how the compilers matched up in his testing."

I think there's some merit to blaming the reporter for being negligent. But it's important to note that that does not in any way, shape or form excuse the behavior of the police in this matter.

Frankly, I think individual officers in cases like these should be held personally responsible for infractions they commit, even if they're just following orders, and even if they didn't know any better. It happens all too frequently that some anonymous police or other organization gets blamed, and the consequences to anyone personally are then irrelevant at best. Perhaps some committee harasses those involved; or the police pays some fine (but that's really the taxpayers paying it, after all) - but at the end of the day, the actual people that in all likelihood intentionally violated other's rights get away scott free.

And there's no pushback from inside the organization, because, well, nobody ever got fired for following orders when there's even a whiff of plausible deniability here. Nobody is taking responsibility for their own actions; so it shouldn't surprise anyone that the police act irresponsibly and unethically despite the fact that most people involved only ever had the best of intentions. If you want it to be normal for the officers in a raid to question the need for it, the circumstances in which it is made, the force with which it is executed, or the damage that is done to those they raid, then there's got to be an incentive for officers to push back and do what's right. Right now, we reward officers for doing what's wrong and punish them for thinking and having a conscience, and that is deeply disturbing.

So? even if true, that's only meaningful if less than 90% of the set of "people that drive and that text" text *while* driving. And that I seriously doubt.

In other words: the frequency of texting surely correlates with the frequency of texting while driving, but I doubt that after correcting for that texting while stopped predicts texting while driving very strongly.

Is it any less "armchair" to simply assume an article is valid without corroboration, or to assume this particular scientist is a fraud without actually checking?

Just because it's more easily said than done doesn't make it untrue - and I strongly suspect none of us particularly care about these specific results anyhow, so of course we'll just comment from afar without actually doing anything.

I mean, if this bothers you, do you have an alternative suggestion?

You suggest that the 5th applies equally serious limitations to all laws, and that therefore Noryungi's argument is irrelevant since it would equally apply to a good law.

I'm not so convinced that's acutally true: The 5th applies particularly well to "crimes" that affect no others. And laws that try to control not how you treat others but how you treat yourself are perhaps intrinsically unwelcome. If you're not even free to make your own choices even when they don't harm others... well, what exactly are you free to do then? Choose a favorite color as long as it's red, white or blue?

Indirectly, the 5th encourages laws that affect how people treat each other or behave publically, and discourage laws about private, unverifiable behavior - and indeed child pornography unfortunately falls in the latter category. And perhaps that's not surprising, because the laws aren't actually targeting the appropriate crime - the "problem" (hopefully) isn't trying to impose control on people (even if you think they're guilty of thoughtcrime), the problem is that it might encourage actual abuse of children.

I think it's wise not to let an emotive but ultimately rather rare crime undermine something so fundamentally beneficial to long-term sustained freedom. The 5th isn't just a good law now, it encourages the system of laws to stay that way, and that's something that we really shouldn't take for granted.
