  • Know the real culprits

    Jump

  • NYC has ~3.75mil housing units.

    Based on your 5amp draw, thats 600w, which a bit on the low side, but we can use it as an average. Assuming most (75%) of residences have AC units, 2.775 million AC units try to run at the same time, using 1665 MW.

    Also, please stop using that 150MW usage of times square, particularly if you're taking it from GoogleAI. I cannot find ANY data supporting that (see possible originating claim for its use here).

    Data instead suggests ~35MW draw for the billboards, using a huge overestimation of the draw (since it assumes all buildings in times square have the same number/size of billboards as times square tower, which is false). This is ~2% of the energy required/used by AC units (not including starting draw), which is tiny.

    Its worth us pushing for, but lets be clear about what kind of impact that will have on the grid.

  • Apparently Canadians are notorius cheaters in the sport of Curling

  • Yeah, I agree. I think its extremely unlikely that this was intentional in the sense of cheating. It'd be a weird way to cheat.

  • I appreciate you finding that article - interesting one.

    I'm very much amateur curler, and can't see how that tiny touch would impact it, but maybe it does at that level of competition.

    Using a perfect shot to stop on the button with no spin, and energy= all kinetic (1/2mv2) =friction energy(F*deltaX), we get a release speed of 1.8m/s (with a .006 coefficient), and a 2.98m/s speed (with a 0.016 coefficient).

    Using the same equation, I go ahead and rerun the number, but adding a distance of 0.1m, a value I used as a good approximation of a reliable accuracy of an Olympic throw, and a time of 0.2s (the approximate time I estimated based on the video), which means a deltaX2 of 0.36m, or 0.596m.

    1/2mv2+fapplieddeltaX2 = ffrictiondeltaX Fapplied comes out to 0.326N to 0.526N which is a miniscule amount.

    That seems to indicate that a tiny touch DOES have the potential to make a significant difference. Some sources say 0.25 to 0.5N is required for a keyboard press, so its roughly on par with that

    But, how much of a difference does the sweeping make on stone speed? Its easy to say that tiny change can impact things, but how does it compare to, say, sweeping hard vs not sweeping?

    This study shows a sweeping change of 45+/-8mm. Thus a change of 25% on top of that is not insignificant.

    So the last question is, does it make sense for someone to train specifically by cheating this way rather than doing it right and just pushing off with a more accurate force? That's likely going to be subjective, but seems difficult to me.

    Who knows, maybe this is a crutch and it is making a difference. Sounds like they need to stop doing it any case, whether a way they've trained or not. Or wear a camera showing they don't touch the rock and just hover their finger behind it.

  • Canada not on track to hit net-zero by 2050, or meet any climate targets: study

    Jump

  • The problem I have is with how productivity is measured. Either GDP or GNI are both negatively impacted by positive planning and bureaucracy, but are driven positively on paper by cheap, breakable goods requiring regular repairs and replacement.

    For example, City/designers of a road take an additional 500 hours to do design work which provides an increase of 10 years in lifespan. Now that doesn't need to be repaired for longer, meaning less future costs (driving down the cost side), while at the same time increasing the hours spent. This has a negative impact on GNI, but is actually a GOOD thing by any rational persons view of the situation.

    Or someone produces a set of clothes at a reasonable price that lasts twice as long. If people all move to that product, our GNI would drop despite that being a positive change.

    Or thousands of frivolous or stupid lawsuits due to problems avoided by proper planning and/or bureaucracy show up as a benefit to GDP/GNI despite being a waste of time and money.

    Using productivity as an end measure misses a lot of important points and measures that a modern society should be aiming for.

  • Indian gangs are terrorising Canada

    Jump

  • Sounds like the "loophole" we need to address is our lack of funding courts and justice systems - a problem seen Canada wide. Seems like a very easy and popular way to solve the issue.

  • Ottawa sees dramatic drop in speed compliance after photo radar scrapped

    Jump

  • Ontario only just allowed speed cameras at all, and specifically only in community safety zones recently, which would be why you haven't historically seen them. Most municipalities only had a few so cycled them through their CSZs.

  • Carney reaches tariff-quota deal with China on EVs, canola

    Jump

  • I can't say I'm too surprised. I'm not involved in the auto sector in anyway, but the media I've seen about it with respect to Canadian manufacturing has been all negative - US companies or US owned companies pulling their manufacturing out of Canada despite deals made (looking at you Stellantis). If our auto sector is diminishing/pulling out, what do we have to protect?

    That being said, I'd like to see more manufacturing jobs here as part of that deal, but I'm entirely uninformed on how that would work or what it would look like.

  • Ottawa sees dramatic drop in speed compliance after photo radar scrapped

    Jump

  • Problem is people aren't good judges of what is, in fact, a safe speed.

    Edit: the second problem is that making it feel unsafe while not being unsafe (or unfeasible to maintain or prohibitively costly) leaves very few options.

  • Ottawa sees dramatic drop in speed compliance after photo radar scrapped

    Jump

  • Studies done up and down streets and in areas with rotating speed cameras show a long lasting impact in the areas most likely to have children crossing the roads.

    Its not a fix-all solution for everywhere, but its sure as shit better than what we have, and the revenue from them was legislated to be used TO create those traffic calming measures you want.

  • Cramped conditions questioned on recent WestJet flight

    Jump

  • Wild. I'm a tall guy (6'5"), and I can just barely squeeze into normal seats if my wife is beside me, letting me knees flare out wide. I cant imagine I'd even fit into these seats, particularly if I didnt know/realize this was a change that had happened.

    Time to avoid westjet until they sort out that shit.

  • Grid-Scale Bubble Batteries Will Soon Be Everywhere

    Jump

  • Unless I'm mistaken, hydronic systems like those USUALLY require a pump to circulate the water.

  • Canada Post is already one of the world’s most cost-effective postal systems

    Jump

  • I'm glad there IS data to do this comparison. Nothing I've seen from proposed cuts has made me believe that they are in the best interest of mail delivery, and its good to see that Canada Post is doing so well relative to other countries.

  • Canada's inflation rate stayed flat in November but grocery prices grew at fastest pace in nearly 2 years

    Jump

  • I'm confused - are you arguing for lower property values as a driving method to reduce COL, or for trying to redistribute housing prices?

  • Transit violence rising across Canada — in some cities by nearly 300%; Exclusive data shows crime rates still well above pre-pandemic levels

    Jump

  • 50 per 100,000 people.

    I don't think we should be using the States as our goal/bar as to what is normal or acceptable for violence. What are the rates in Europe? What about Japan or Korea?

  • The military plans for a volunteer force to defend Canada

    Jump

  • Arguing that were not better than the US or Russia (the two biggest neighbours and both much more aggressively imperialistic than Canada), is extremely disingenuous.

    I think Canada has the potential to do better and I'm not about to give it up or roll over for another country to come in, particularly one like the US who has shown an incredible swing towards facism and aggression to LGBTQ and POC. Me defending this country, if they were to invade, would have direct benefits to those of my family who are LGBTQ and those of my friend group who are immigrants. Arguing that because Canada has a problem with wannabe monopolistic companies and a bleed over of American individualism its basically as bad as any other is a stance I disagree with.

    The most likely deployment for these forces would be natural disasters and support - something I'm interested in doing anyway. If this does come out its something I'd explore and see if its a good fit.

  • Ontario to consolidate conservation authorities, create new oversight agency

    Jump

  • Its been a nightmare working with CAs recently (last 3yrs), but that's largely due to budget cuts and staffing losses.

    Fund them properly and set strict guidelines for plan review turnarounds, and you'll see improvements.

    But alas its the classic "defund then claim its not working" be that he pulls everywhere.

  • Prime Minister Mark Carney says Canada will double its non-US exports as Canadians can’t rely on US

    Jump

  • I mean at the least it looks like we're taking some steps to avoid the clusterfuck that the USMCA resigning is likely to be by getting ahead of it.

    Its not hard to double exports to other countries when your main trading partner (US) stops taking your stuff. Talking out of my ass, but it seems like doubling exports to other countries wouldn't be that hard when we wind up having a surplus because US trade dries up. Seems like it'd push prices of our goods lower and hurt Canadians, which is what he seems to be implying to me.

  • Woman fined £150 for pouring coffee down drain

  • Lol, this is not anything new or crazy - All of NA infrastructure is built the same way. I'd be surprised if there were many places in the world that weren't built this way.

  • Canada’s largest private sector union urges government to keep surtax on EVs imported from China

    Jump

  • The union said lifting the surtax now would risk undoing recent investments in vehicle assembly, battery production and critical minerals. It is asking Ottawa to extend the surtax for at least 24 months, broaden it to include EV and battery components, and reinstate federal EV rebates restricted to Canadian and North American-built vehicles. The union also wants stronger enforcement against goods made with forced labour. Unifor said Canada should align its approach with the United States and Mexico. The U.S. has combined tariffs of 127.5 per cent on Chinese EVs and plans to restrict connected car technology by 2027, while Mexico raised its EV import tariffs to 50 per cent this year after Chinese vehicles surged to 70 per cent of its market.

    I don't disagree that China is going to flood our markets with cheap EVs, with huge impacts on our own auto plants.

    But holy fuck guys, we just dropped our previous pledge of 30% EV by 2026. What's the plan - indefinitely push off electrification? We're getting lapped by China on renewable and electrification technology, and its only going to get worse if we dont FORCE companies to electrify and move faster.

    On top of that, the US companies are all starting to move their car manufacturing back inside the US. Our auto sector is in serious trouble regardless of our move here, and continuing to put our eggs in the US basket is a mistake, IMO.

    Keep a 50% tariff, which still places these cars into an affordable price point here. Given the problems the China auto sector is in, they'll likely still move cars with that rate. Then earmark those tariffs to retrain those auto workers, or support a canadian EV manufacturer.
