Comment Re:Would a Spar be Repairable? (Score 1) 57

Woah... Dumb question, but would a wing spar be repairable or replaceable?

Coward said, because when the wing falls off at 30,000 feet, rest assured - it's okay, because Airbus has good documentation. All fixed.

No, of course a broken spar is A Very Bad Thing when it happens in midair.

Is this changing-the-timing-chains-in-an-Audi difficult, or is this replacing-your-spinal-cord-without-killing-you impossible?

Are these planes repairable? I think it's a reasonable question.

(Of course, with the Audi, if has anything more than a loose gas cap it's not economically feasible to repair, but that's what you get with European engineering.)

Comment Re:I want to see inexpensive plugin hybrids but .. (Score 1) 135

You might want to read up on how current hybrid vehicles actually work, 'cause it seems you have more than one misconception going on.

I have. For instance, my latest vehicle is the Ford F-159 XLT,, the full-hybrid model of the F-series pickup truck line. Power train is:
  - 6 cylinder dual-turbo engine. (runs low power but approoximately doubles output when a lot is needed.)
  - 47 HP motor-generator "pancake" on the engine side of the ttransmission, to scavenge / return power to./from a 1.5 kWhr lithium battery.
  - 10-speed automatic transmission, working with the lithium battery;s main alternator to fine-tune match the engine/mogen to the current driving situation. Max power of engine plus hybrid mogen; 430 hp.
  - full four wheel drive.

So it's primarily a gas-engine power train with an electric-car motor mechanically coupled to the engine shaft. Many other hybrids, from the venerable prius onward, are similar, with plug-in variants having a big scavaging/peaking battery good for pure electric operation of tens of miles rather than a minute or so and a wall-powered charger added.

What I'm looking for is essentially a pure electric - totally electronic "transmission" consisting of alternator(s) between the batteries and the motor(s), plus a tiny engine-generator able to burn gas and feed some teens of KW of charging power into the batteries when running down the road or parked near it.
 

Comment cobalt chemistry, not so nice. (Score 1) 115

Do the Waymo batteries use one of the lithium chemistries including cobalt, or a non-cobalt chemistry such as lithium iron phosphate?

Cobalt chemistries have a higher power/weight and energy/weight ratio, which made them the go-to chemistries for vehicle batteries. But they also produce oxygen when the cells overheat, leading to an unextinguishable runaway fire hazard: A burning cell makes enough heat to ignite the adjacent cells, so the whole assembly of them goes. Bad enough when it's a car's worth, but a disaster if it's a shipping-container sized module of a utility energy storage site. (And even worse when the site is a building full of racks, which someone had "protected" from fire with water-spraying, equipment-shorting system, so the whole site burns up, as happened recently with one in California creating a toxic mess.)

That's why purpose-built stationary lithium energy systems use non-cobalt chemistries - heavier, but a shorted cell just kills itself without getting hot enough to light off its neighbors.

I want to see inexpensive plugin hybrids.

But not like the current ones, which are primarily an engine/tranny powertrain with a motor/generator + small battery for scavenging downhill/braking energy for later accelleration/uphill/cruise/power-boost.

I want ones that are primarily a battery-electric with a small aux engine-generator (say 15-20 HP range), big enough to power crusing with a bit left over for gradually charging. That would let you range-extend by the size of your gas tank plus fillups (i.e. indefinitely if only gas is available) or go from battery empty to back on the road in a couple tens of minutes.

The backup engine would only run at max-efficiency speed and could use an atkins-like cycle (see "liquid piston engine") to get the max power out of the fuel. Most operation would use power-grid charging (when available and cheaper than fuel).

Comment YouTube Audio Quality - Bad Production (Score 1) 100

It's just that the entire YouTube is appallingly bad.

A lot of the audio production in individual videos is really bad. This isn't anything to do with YouTube per se, not their compression algorithms or other features. A lot of YouTubers have absolutely no concept of microphone placement, of using audio compression, of reducing background noise. All of which are things which will drastically affect audio quality and the ability of a speech-to-text model to create subtitles.

It would be nice if YouTube would normalize all the uploaded videos to one set standard. Note I'm not suggesting that they compress the videos as that might change the intended presentation of professional audio productions. I just mean peak-finding normalization which could be implemented losslessly and without breaking existing video links.

Having said that, when I look at my own channel - and I am not claiming to have great audio; I have a host which would destroy a lavalier microphone in mere seconds. YouTube's subtitling is really good. It automatically switches between English and French and Hebrew, and even with a fair bit of background noise (welding, grinding, cooking, crowd noise, music) it generally gets the text correct. So I don't know what the original complaint is, except that it's not perfect. Well, guess what, neither is human hearing. How about that famous Jimi Hendrix line, "Excuse me while I kiss this guy."

Comment Look up "human shields" (Score 1) 255

And a douche bag of a president who drops bombs next to schools and kills 135 kids . Should resign on the spot for that.

Look up "human shields", the practice of siting military targets among (or in or under) large collections of non-military civilians, in order to deter strikes against them or produce propaganda claims of atrocities when they're attacked anyhow.

In such situations the fault for the "collateral damage" is assigned to the side that set up the arrangement, not the side that hit it.

Nevertheless, it should be noted that the US has been trying very hard to use precision munitions and extreme military intelligence to take out military targets with as little harm to the innocents they're embedded among as possible, with impressive success. Compare the amount of collateral damage in this war to any of those conducted in the 20th century.

Comment Comparing your accent to claimed residence history (Score 1) 255

He's doing the bare minimum sniff test of verifying that *you* are the guy whose name is on the bookings and not someone sneaking in on someone else's name who can't even pronounce the name on your fake id.

At least in the case of people claiming to be returning citizens I've been told that they're comparing your accent to your claimed residence (or residence history).

Different words are acquired at different ages, and many are pronounced with regional variations. An expert can talk to you for a few minutes and come up with a pretty good age-map of where you lived as you grew up. An agent with a modicum of training can detect a mismatch between how you pronounce certain words and your claimed residence and pass you through quickly or keep you around and drill more deeply. (If you now live in an area with a regional accent wildly different from where you grew up it can help to answer a where-do-you-reside question with "Footown, but I grew up in Barstate".)

I presume they are doing something similar, though no doubt with lower resolution, on the world-wide level for visitors from other countries.

Comment Did the Space Station put Pepper in the Radiator? (Score 1) 39

I'm reminded of all the BMW cars I've previously owned where it was often said "If there's no oil under it, there's no oil in it"...

Ahh, yes... German cars. If every decent car company does something with 6 parts, the Germans will find a way to make it require 27 parts. All of which are horribly expensive and require specialized tools to install. Or they'll put the timing system at the back of the engine so that a routine service item becomes an engine-out procedure. Garbage cars driven by people who don't know any better.

The space station leak reminds me of an old trick for a leaky cooling system in a car: put pepper into the radiator.

The little flecks of ground pepper get washed around the cooling system and eventually block tiny cracks in the radiator or other places. Putting a raw egg into a *cold* radiator will do the same thing; when the engine gets warm it cooks and blocks the leak. Both of these tricks have saved me on the road, they do work. But they are temporary and you need to thoroughly flush the cooling system after the repair.

I wonder if the Space Station has had the same sort of thing happen - airborne dust blocking a leak?

Comment The Pedophile Prophet is the Problem. (Score 1, Insightful) 173

For 17 years before Oct 7, Gaza lived under an Israeli-imposed land, air, and sea blockade that restricted food, fuel, medicine, movement, and trade, widely described as collective punishment of 2+ million civilians.

Or, maybe because Palestinians keep on attacking Israelis (and everyone else) in the name of their Pedophile Prophet - peace be upon the illiterate 7th-century caravan robber and warlord - so Israelis rightly have no interest in incorporating them into civil society.

clean water became scarce,

...because the Palestinians were digging the water pipes out of the ground and turning them into makeshift rockets...

electricity was limited to hours a day,

...electricity and desalinated water which were both being provided by Israel because the Palestinians are more concerned with appeasing their Pedophile Prophet than with getting their shit together and building power plants and desalination plants...

making Gaza unlivable.

Gaza is unlivable because of the Gazans. Somalia is unlivable because of the Somalis. All of the Muslim world is unlivable because Islam is an evil ideology. The Jewish people (People of Judea) were established in Israel 6,000 years ago and laid the groundwork for the establishment of Western Civilization, approximately 4,500 years before a self-important warlord and pedophile declared himself to be the messenger of something called allah.

And what is allah? God is supposed to be omniscient. So He tells us to call Him yud-hey-vav-hey... but then after meeting the Pedophile Prophet, He changes His mind and wants to be called allah? An omniscient being didn't know in advance what He wants to be called and changes His mind about His own name? This is NOT the God of the Jewish and Christian people.

You're free to believe whatever you want. But when what you believe promotes death for the sake of forcing your beliefs on others, it's time for your ideology to take a long and hard look in the mirror.

This is what Israel is fighting. How to beat your wife - according to Palestinian TV.

There are two kinds of people in the world: there are those who you can negotiate with, and there are those who fly airplanes into buildings. You cannot negotiate with this. You cannot make peace with this. The only thing they understand is being completely and utterly obliterated, and then playing the victim.

I wouldn't wipe my ass with the Palestinian flag. Doing so would be disrespectful to my feces.

Comment Electronic Shelf Tags are essential (Score 2) 108

I thought everything was a dollar!

Right... I worked for The Beer Store, the brewer-owned private company which distributes beer across the Province of Ontario. Our Premier (roughly equivalent to a State Governor) made a campaign promise of "A buck a beer!".

So, a new empty can cost roughly $0.20 at the time. The law in Ontario is that shelf prices include tax and deposit. So, the can is $0.30 - twenty cents for the can itself, plus another dime for the deposit to make sure the used can comes back for recycling.

Now, on top of that, you have to make a food-grade beverage, pay your excise tax to the federal government, and then there have to be profits for the manufacturer and the distributor/retailer (that would be Brewers Distributing Limited dba. The Beer Store).

Customers would come to me and - with that "I know more than you even though I haven't held a job in 16 years" expertise - tell me that we were going to be carrying "buck a beer" because they voted for Doug Ford (who also cut their welfare increases).

"When do you get it? It's gotta be soon!"

"The first shipment arrives February 31st, so mark your calendar!"

I must have used that line 500 times. Only one person realized that there's no February 31st. To his credit, he had to come back to the store to tell me. LOL

Exactly ONE brewer made the Buck A Beer - Cool Brewing of Etobicoke, in Doug Ford's riding. We were lucky if we got a single case (24 beers) a month. Promise fulfilled... Right.

Anyway... The Beer Store's shelf tags were printed at the distribution center and sent to stores with truckloads of beer and empties in and out. Of course, you always had too many tags you didn't need, and were always short of the shelf tags that you did need. If a tag was outdated and wrong, you have to - ethically if not legally - honour the price. And, of course, if a tag was damaged or lost, there was no tag for that product. All of this hearkened back to The Beer Store's roots as Brewer's Retail where everything was behind a counter and we had a selection wall. In a newer self-service store like mine, this did not work.

Electronic shelf tags were implemented. It was amazing. Snap the tag into place on the shelf. Scan the tag. Scan the product. Press a button. The scan gun would beep and a moment later, the tag would update with the item description and price.

Price changes? Automatically updated on all tags.

Now, something about selling addictive substances: Sometimes someone decides that the item's price is what they have, not what the shelf tag says. And they will argue with you until the cows come home. You get jaded to it.

"That will be $2.25 for the can of Pabst Blue Ribbon 5.9."

"The tag says $1.95 so you have to give it to me for that. You forgot to update the sticker."

"No sir, I assure you that it doesn't. They're not stickers, they're electronic and tied to the POS."

"It says $1.95."

"Sir, if the shelf tag says $1.95 for Pabst Blue Ribbon 5.9, I will give you a full case of it. On the house."

For a moment, they're elated. And then they realize that I'm coming out from behind the counter to call their bluff. In front of the lineup of impatient customers during the daily 10:01AM opening rush. Catcalls. Whistles. Jeers.

Walk over with the dude... shelf tag says $2.25 for PBR 5.9. Now, at this point, I'm annoyed, and I'm not going to short my till $0.30 for him. Or suggest to him an alternative beer that is $1.95 a can. If he'd just passed me all his change and come up a little short, I would have covered it. Personally, out of my pocket, if I didn't have a few nickels and dimes perpetually floating around my cash. I've spent way too much time on both sides of the counter at The Beer Store, so I have plenty of empathy - just don't be an asshole.

Anyway... Dollar stores are dealing with customers who are on the very bottom economic rung, whether from addiction or for some other bad life event. Now, sometimes these people are a nickel away from being able to afford a can of beer - or a jar of baby food. I have seen split tender three ways for a $2 item - $0.50 from returning 5 empty cans, $0.97 by scraping a prepaid Mastercard from last Christmas to the last cent, and then $0.55 from under the sofa cushions or wherever. Unexpected price changes can drastically upset plans these people have made to get a few supplies with their very last dollar.

"I can get a box of Kraft Dinner at Dollarama for $0.50, and two cans of cat food at A Buck Or Two with the other $0.50..." I've seen it, and I've personally lived it.

The shelf tags, especially at a dollar/discount/alcohol/cannabis store of any sort, must be accurate. As an experienced retail manager, electronic shelf tags are simply essential.

You can sell the boss on implementing them with the operational savings, the labour of having to change stickers with every price change. Electronic shelf tags will pay for themselves in very short order.
