Not to nitpick, but wombats can actually run pretty fast when they want to - up to 40kph. And I reckon kangaroos, while fast, aren't very manoeuvrable; if they're on a line they tend to stay on that line, right into the path of the vehicle.
Koalas, though, geeze - they're slow, drunk usually, and don't give a damn. I almost hit one once, slamming on the brakes and almost going off the road, and the damn thing didn't react at all, just kept unconcernedly strolling across. Doubt anything can stop them except fences combined with safe crossings (tunnels, wildlife bridges).
> during the 2004 Indian Ocean tsunami when broken hazardous waste containers eventually found their way onto Somali shores leaving a large majority of the population suffering from various illnesses, such as radiation sickness
This sounds extremely doubtful. Tsunami-borne hazardous waste containers breaking up in Somalia en masse? Radioactive waste!? And a "large majority" of Somalians were poisoned by this?
I don't usually like to play the wiki-pedant but a very big  on that.
I have to admit I love the sound of a good engine - and aeroplanes, and boats, trains, everything. It's the sound of power. Watching cars race without that sound is a far less emotive experience. One of the commentators on tonight's Bahrain race said that the safety car sounded much better than the race cars, and I wistfully agreed.
That said, I do think some people overdo it a bit and I actually like that FIA is willing to force innovation, even if it's (initially?) unpopular.
Mercedes has been dominant the past two races as well so it's not necessarily a spoiler to say they have been owning the season. On the other hand today's race ended a few hours ago and I didn't expect to run into race results on HN of all places. Oh well.
To be fair to him, a thread all about which team is dominating F1 is the kind of place on HN that I would expect to see races discussed. Not sure that shouldve taken you by surprise! Anyway, sounds like the race was good enough for you to enjoy anyway.
Were we watching the same race? The last 11 laps were an epic battle between Rosberg and Hamilton, and the mob contending for points was no less thrilling. I thought it was a great race, at least at the end.
And have you already forgotten 2013? Red Bull won every single race in the second half of the season. Yeah, Mercedes is on top, for now, it's not like a constructor has never been dominant before.
Is it though? We haven't even arrived in Monaco yet, anything could happen and the drama has been amazing to watch so far. Take tonight for example... Vetel being instructed to let Ricciardo pass and complying, Force India going 3/5, Hamilton and Rosberg dueling, Massa(??) blitzing the field on the start. The president of Ferrari walking out in disgust. That horrendous flip...
This doesn't even get into new arrivals like Magnussen and his amazing debut. This season is far from over and getting more interesting by the day.
> There's nothing in the comment you replied to that indicates any cavalierness about "gay rights"
You missed the point. The GP's comment, by dismissing gay right's relevance to mozilla, implicitly treated the matter in a "cavalier" manner.
Let's do a little find/replace to prove the point. Eich donated $1000 to the KKK. The GP notes that lynching niggers has nothing to do with the day to day operations of Mozilla, so what's the big deal. The parent is dismayed by how trivial black person's rights are considered by HN. What's your comment, tptacek?
After using the toilet, do you wash your hands, or just wipe them?
You've just demonstrated why washing toilets are superior. I cannot understand our misplaced, hollow pride in not adopting something which simply works better. I've even heard some especially crazy people try to say the japanese toilets are "perverted" - the hold tradition has on some people is just insane.
Japanese toilets are simply better. For some bizarre reason we've resisted adopting them here. It boggles the mind.
Installation involved adding a T-adapter to my sink's cold water line. The whole setup takes about 5-10 minutes if you know what you're doing, or about 30 if you don't. Even if you know nothing about plumbing, you can install this thing with some patience (and probably in well under an hour).
I've been very happy overall. There are lots of similar bidets for varying prices, but the core functionality can be had for $25. I haven't felt the desire to spend any more, this thing just works.
We go through a lot less toilet paper, though we still use some for the drying. This may be too much information, but I do feel subjectively much cleaner. When we travel somewhere without a bidet, it's definitely on the edge of my mind that I miss my setup at home.
I do get weird looks when we have company, but who cares. Continue smearing poop on your butts, heathens.
Woah, neat! My girlfriends whinges about using too much toilet paper (which... well, she does. Way too much) and I've always loved the washlet style things, so this is awesome! Thanks heaps for the link :)
I like that it's cheap but pretty much the bare minimum feature of a Japanese washlet is to let you set the temp of the water. Lots of places I've lived the water gets pretty cold especially in the winter. OW! ;)
I also used to think of Japanese toilets as weird , and overly complex for the task (that may be partially true) but after buying a 35 dollar bidet attachment for my apartment toilet, using any other bathroom feels barbaric. I've resorted to carrying moist wipes when out of town, but even those are a far cry from the efficiency and cleanliness afforded by a washlet/bidet.
I would love for the rest of the country to get over whatever biases or anxiety keeps us from mainstream adoption of an objectively superior system for bathroom hygiene.
After experiencing an electronic bidet in Japan for the first time during a holiday, I returned home wondering how on earth did I manage without it. I was sold. I bought a YoYo 770 for 800$ as soon as it appeared in Europe.
Exactly. There's something about water, the universal solvent and universal lubricant. It's probably the same reason that same doctor recommended sitz baths, and a big secret to most bulk forming fiber is that it absorbs a lot of water.
> Japanese toilets are simply better. For some bizarre reason we've resisted adopting them here. It boggles the mind.
That's not true. One major reason we don't adopt them is the cost of installation. If you have an existing house, chances are there's not an electrical outlet next to the toilet. Why is is important? Because Japanese toilets require power. Why does this suck? Electricians are not keen on working on bathrooms because of all the pre-existing pipes, so to do the job right, they'll probably have to rip off all the walls. Once the electricians are done, you probably have to hire a bathroom remodeler to fix everything up, because again not many licensed people are keen on working on the bathroom unless they specialize in it.
First, the outlet for the shaver and blow dryer are far enough from the toilet that you'll need an extension cord that crosses your sink which isn't going to work. Second I've never seen a false ceiling in a residential bathroom. Not that having one would make it a lot safer. The bathroom is not a place for a hack. You really need to do it the right way or not at all.
I'm skeptical that this is the primary reason. Everything you say is true but a LOT of people spend loads of money renovating bathrooms in the US. Just go down to a Home Depot and look at all the fancy sink, shower, jacuzzi, etc. hardware. Yet I've never seen a Japanese toilet in an American home. In general, toilets just don't seem to be something that gets any sort of special treatment in bathroom remodels. And none of the companies that make all the aforementioned hardware make anything other than standard sit toilets AFAIK.
I suspect it's just something that most Americans (and Europeans) simply haven't experienced or are even aware of. And it probably doesn't help that the initial reaction is probably negative--which may be why nobody's made a serious attempt to push these in the US.
As I've already mentioned, it's the labor that's expensive in either time or money since there are pipes behind the drywall that you're going to rip apart. Also some people put tile over their drywall, the very people more likely to buy an expensive Japanese toilet. We're talking a few thousand dollars.
I'm just trying to convey my experiences with bathroom remodeling on my own house. Anyone is free to listen or ignore my advice.
I never said it wasn't a valid idea. It's just a hard and expensive one. You guys will find out once you become home owners in the future. Also a Japanese toilet costs the same as a cheap car. If you haven't already guessed, I wanted one for my bathroom for years now. It's just not practical.
What did I miss? OP is arguing that we should wash our behinds for the same reason that we wash our hands. Yet the reason we wash our hands is to reduce a threat that does not exist (at least, not as readily) for our behinds.
And now semantic satiation has kicked in for "behind."
That's a valid point, but not one that directly supports the argument for bidets. Since most people (at least in my neck of the woods) shower at least once a day, personal hygiene is usually accomplished.
Here's the reason it sounds weird to those (like me) that haven't tried: your hands don't have a source of, er, soil, tucked into them in a crevice. So getting them as wet as you like doesn't have any downside.
I've used a Japanese toilet and for me the hand washing facility attached to it is meaningless as I do not understand why would anyone ever wash their hands with cold water. Especially I do not understand people who simply wash their hands by dipping them into cold water for a second.
But maybe the culture of washing hands with warm water and soap is merely in North Europe. And maybe I am illusioned by the effectiveness of warm water.
> why would anyone ever wash their hands with cold water.
Well it depends on the time of the year. In winter, you certainly don't use them that much because water is freezing cold. But as soon as it turns april-may, water becomes lukewarm or even relatively hot in summer months (summers are excruciatingly hot in Japan), so then it's not an issue anymore.
> And maybe I am illusioned by the effectiveness of warm water.
Do you mean warm water is more effective at washing ? There's actually no basis for that. Surfactants matter more than temperature.
> Japanese toilets are simply better. For some bizarre reason we've resisted adopting them here. It boggles the mind.
They are not cheap in Japan, by the way. If you buy a new apartment they are included by default(these companies work like Mafia to secure contracts with new apartment complex builders), but new ones you buy directly from TOTO are like... "what?" when you see their prices.
Do you use soap to wash your hands? or just rinse them off with water (especially if you happened to get a little on you)?
Do you then pick up your chicken wings or pork ribs with your butt cheeks and stick them into your mouth, proceeding to lick off the excess sauce/grease?
I have just demonstrated why your example has a complete lack of logic or value.
FWIW, I use a baby wipe. This uses less water and about the same amount of paper. it actually does a little better job, is quicker and far more economical. My toilet will last 40 years with about 10% of the purchase and maintenance costs. I also carry wipes around to use in public restrooms so while you may get clean at home, I get clean on the road as well.
I mainly do this because I have itching/chapping issues if I don't.
> an ongoing conversation Patrick and I had been having with Colin, not all of which HN is aware of
The knowledge that there's missing context, which was provided in some sort of back room inside-baseball hn-elites secret discussion to which I was not a party and will never be granted access, kind of makes me wish the article had never been posted in the first place.
"Here's my article - which you'll never understand, because you weren't there, because you're not cool enough". Great.
GPUs are ubiquitous. When you have optimizations of hashing algorithms, like for scrypt and sha1 before it, you end up with specialized hardware often coming out of a few hardware companies dominating the entire mining scene.
That means a stark concentration of mining power, because it means "average joe shmoe" can't just start running cgminer on their integrated openCL hardware and get coins at reasonable rates for the money invested (in power).
I think it is too late for litecoin, and would rather see them implement this in a less entrenched altcoin like peercoin, because there is too much inertia and scale now to change it in the litecoin space.
I understand and agree with, to some extent, the argument against centralisation. However, I don't see how this fork solves it - it's switching from one form of centralisation (ASICs) to another (huge clusters of mining rigs).
GPUs may be ubiquitous but it's not viable to run a mining rig with just one, which means that all those GPU miners are basically running "specialised hardware" too. Joe schmoe does not just happen to have an 8-GPU tower computer lying around.
I run a 2-GPU tower and make a couple bucks a day with zero upkeep effort on my part.
It's not totally vanilla hardware like the 15-watt laptop I'm typing this on, but it is common enough I happened to have it already.
With ASICs the barrier to entry is five figures. (Most of the cheaper ASICs have terrible payoff timelines) With GPUs the barrier to entry is far, far lower. You won't make it rich on a $150 GFX card, but you can make some revenue.
My Cuckoo Cycle PoW (https://github.com/tromp/cuckoo)
configured to require for instance 7GB of memory, is
all of the above. And is very power friendly, since
only 5% of the runtime is computation and 95% is waiting
for main memory random access latency...
Sure, if you can come up with a good proof-of-work algorithm that runs well only on CPUs.
It could be possible. The straightforward way would be, I believe, to use an algorithm that has weak parallelism and depends strongly on branching. CPUs are king of branching, and both GPUs and ASICs get ahead by taking advantage of parallelism.
Although, one nice thing about GPUs being the standard-bearer, is it makes most general purpose server hardware useless for mining. That's good in that it makes hijacking a webserver to mine bitcoins, a largely pointless affair.
I've seen some mining rooms which disprove your notion that GPU-only mining will stop the capitalised players having an advantage. They always will.
And yes, it's always a balancing act. The network adjusts the difficulty based on total hashrate, not on power efficiency, which is just an overhead. More and more people will pile in until the difficulty is high enough to render mining unviable. However, ASICs at least will shift the balance more towards hardware costs vs the raw power cost that it is now, and reduce the number of useless components that need to be manufactured, etc.
The difference is if those with capital have a linear scaling of power in the mining or if there is a sheer cliff followed by linear growth, because without an ASIC you can't effectively mine at all.
Everyone has a GPU, and your gpu is usually on the same magnitude of efficiency (assuming its modern) as the optimal GPU miner for any given algorithm. With ASICs, the barrier to entry is huge, so you have less "casual" miners. The casual miners significantly dilute the power of concentrated mining operations.
the energy usage of bitcoin and the altcoins is, in my opinion, one of the few things that could threaten its viability long term. people aren't going to be able to understand the reasoning that this is the cost of decentralization - it's going to look like a phenomenal waste of energy, even if low-powered ASICs are doing most of the work. not that the average consumer has a problem with that, but govts might.
i wonder if there is a solution to the byzantine general's problem with that is resistant to 50% malicious nodes but doesn't require so much energy overhead. even proof-of-stake coins still require energy wasting.
Well, commercial organizations that own office space are already forming and expanding around BitCoin - so the cost of keeping those businesses physically open would be in addition to the cost of keeping the BitCoin network up and running. It's not like we're getting rid of the need for buildings.
If we're going to do that, why not get rid of GPUs, too. ASICs are merely an efficiency increase, just like GPUs were.
I somehow suspect, however, the proponents of this change are not "regular joes", who might have an intel HD2000 in their laptop. And if we're going to play the "democratising" card, with GPU mining it's a lottery of where you happen to live - electricity prices vary wildly around the globe. ASICs help to take that out of the equation, so if anything they're more "democratic"!
As I discussed in another comment, we could get rid of GPUs too, but first you have to find a suitable algorithm that works well on CPUs but not GPUs or any conceivable ASIC. That may or may not exist.
