Comment Wringers on washing mashines (Score 1) 635

The old technology I am giving up are the wringers on top of washing machines.

They're dangerous (you can get your fingers caught) and they mess up more delicate fabrics. Also, the newer washing machines with the agitators that churn the wash around do just as good a job.

Also, zippers. Velcro is much easier to work with and it never gets stuck and it doesn't hurt as much to snag your dick on velcro.

Dr Manhattan is unlikely to come into being from energetic mouons interacting with fissile reactor fuel rods.

I'm sure they said a spider-man was unlikely to come into being from being bitten by a radioactive spider, too. But guess what happened.

Either way, as someone who doesn't know from nothing, I'm completely in favor of bombarding nuclear rods with muons. Because I like saying "muons". "Muons...muons..." If you watch yourself in the mirror when you say "muon" your mouth makes a little kissyface. Fun!

Now please excuse me. This bottle of single-malt isn't going to drink itself.

Comment Image processing (Score 4, Interesting) 181

I use -- and write -- image processing software. Correct use of multiple cores results in *significant* increases in performance, far more than single digits. I have a dual 4-core, 3 GHz mac pro, and I can control the threading of my algorithms on a per-core basis, and every core adds more speed when the algorithms are designed such that a region stays with one core and so remains in-cache for the duration of the hard work.

The key there is to keep main memory from becoming the bottleneck, which it immediately will do if you just sweep along through your data top to bottom (presuming your data is bigger than the cache, which is typoically the case with DSLRs today.) Now, if they ever get main memory to us that runs as fast as the actual CPU, that'll be a different matter, but we're not even close at this point in time.

So it really depends on what you're doing, and how *well* you're doing it. Understanding the limitations of memory and cache is critical to effective use of multicore resources. You're not going to find a lot of code that does that sort of thing outside of very large data processing, and many individuals don't do that kind of data processing at all, or only do it so rarely that speed is not the key issue, only results matter. But there are certainly common use cases where keeping a machine for ten years would use up valuable time in an unacceptable manner. As a user, I am constantly editing my own images with global effects, and so multiple fast cores make a real difference for me. A single core machine is crippled by comparison.

Comment Sources of water (Score 1) 708

The moisture source for lakes and rivers is -- inevitably -- precipitation over lands upstream. Either as direct runoff, or as recurring eruptions from underground aquifers. If the prevailing winds don't bring the more humid air over the cooler, higher landscape, sure, you'll see drought. But you'd see it anyway, more heat or not. When the prevailing winds are bringing more moisture over those same types of terrain, you're going to see more precipitation, not less.

The historical record bears this out. When the earth is warmer, we get (a lot) more plant growth. That's simply not going to happen if the precipitation is reduced for any reason. And, at least as far as I am aware at this time, there is no mechanism that would cause reduction in precipitation. Warmer air holds more moisture, yes, and that effect is in full view in the tropics -- with deluge level rainfall when that moist air hits colder atmosphere and the moisture inevitably precipitates as rain. 400 inches / year as opposed to about 100 inches / year in otherwise similar temperate regions.

I would certainly agree that if the wind patterns change, then the rainfall will too. In both directions. But it seems a little farfetched to say that such changes will result in a consistent decrease in winds traveling onshore. What would such a claim be based upon?

Comment Re: Impacts (Score 1) 708

Is this year actually a warmer year? Didn't I just read that we're in a 20-year hiatus in the warming trend?

Yes, warmer air holds more moisture -- anyone who has worked the steam tables to convert between relative and absolute humidity knows that (and I have done so for my auroral photo opportunity prediction freeware), but it's also susceptible to precipitating more moisture when convection brings that moist air up into the colder altitudes. That's why tropical rainfall tends to be in deluges as compared to, for instance, the typical rain shower in Pennsylvania. We know for a fact that the tropics are warmer and wetter in terms of rainfall amounts per year -- and that since they are warmer, their air can hold more moisture. But that's not stopped them from having much more rainfall than anywhere else. While there certainly may be outlier statistics, the general case seems clearly to be: warmer = wetter = more rainfall.

Temperate rainforests get as much 100 inches / year. Tropical rainforests get up to 400 inches / year. If it's not the heat that's doing it, what do you propose is the mechanism?

If it *is* the heat that's doing it, then what is the mechanism where more heat, heat that corresponds with previous tropical climates in the earth's past, won't repeat the same effect here? Looking at the past CO2 level graphs as correlated with plant growth and temperature, there's a very strong correlation with CO2 and plant growth, and with temperature. Plants love CO2, but they still need moisture to survive, and where there's more plant growth, it's pretty much a certainty that there's a significant water supply.

So far, anyway, the idea of warming in the tropics -- or anywhere there's basically unlimited water and related prevailing winds -- leading to drought seems to be a non-starter.

It's not that I can't accept it, it's just that to accept it, I need a sound scientific reason to do so. Just saying that one expects drought in the tropics seems like hand-waving at this point. There are plenty of legitimate concerns - a slight, very, very slow rise in sea level, movement of crop-appropriate bands in cultivated areas, that sort of thing, but tropical drought doesn't appear to be one of them.

Also, recent news shows increased plant growth worldwide... something to think about in a situation where CO2 is known to be increasing at an accelerated rate.

Comment Re:Broadwell (Score 1) 181

But if I'm trying to game on an old i5-750, wouldn't this be a good time to upgrade to one of the cheaper 4-core Haswells that are running 3.8mhz instead of 2.7? Maybe a Haswell i5 (I guess, I'd need a new mobo then, right?) And the latest PCI-E for a new graphics card.

I don't like to buy the newest and best, but when the second newest becomes cheap. I've got a really nice case, but I'm not sure if I could put a new processor into my old motherboard or if it would even be worth it.

I'd like to do something before the fall games come out. Would I be better off just upgrading my old Radeon HD6850 to a nvidia 760 or a Radeon R9 285 or something?

And did I fall through a wormhole and end up at Tom's Hardware?

Most won't even care about that, they just install without reviewing.

I doubt it's much different in other platforms. Mac OS or Android or Linux. When there is an update, most people don't have the time to carefully go over what it's doing. Nor should they.

When the plumber comes to my house, as he did yesterday, all I care about is that the hot water is coming and the toilets flush. I don't crawl under the sink to see if he properly greased the pipes or whatever the hell it is plumbers do.

I have met people who work for Microsoft and Apple and they are neat and earnest and are by all appearances proper and trustworthy citizens. I've also met people who contribute to open source OSs. They look like the guy who stands on the on-ramp with a sign asking for change. A little bit dangerous with greasy hair and a a psychotic glimmer in the eyes.

I'm kidding of course, and just tweaking people who use Linux (like myself), but as Eclipse (played by Frank McRae) said to Sylvester Stallone upon his imprisonment in the classic American film Lock Up, "You gotta trust somebody. Let me hip you to the joint."

Comment Re:G'Day Valve, (Score 2) 139

some might find it more convenient than dealing with dodgy/illegal web sites, poor quality cracks, possible malware, and other annoyances.

The top torrent sites are a lot less "dodgy" than uplay (and have better uptime), and the best of the scene outfits put out cracked products that are often more stable than the companies that produce the games.

How many times have we heard about games that had huge problems because of their DRM that were fixed in the torrent?

There may be arguments for using Valve/Origin/Uplay etc over torrents but the ones you mention aren't really among them.
