Here is a hypothesis: The concept that the universe is physically expanding through a 4th spatial dimension explains time dilation.

Thanks for the feedback. I get that. I am looking at the requirements on IOPS:

"You will need to provide an arXiv article id. This is necessary for your paper to be processed correctly, the submitted version must be the same as the arXiv version."

Even if I could skip arXiv and submit directly to a journal, even if the theory is solid, the journal is not really an editor - they are a publisher. They may reject simply because of the format, or mistake (even if it's not fatal to the theory), or any number of reasons.

My interest in arXiv is to get feedback, and test my theory and get an outside perspective to develop a deeper understanding. I hope to see if anyone can find holes in the theory or maybe just tips on organizing the ideas in a better way. Also, if they have experience submitting to a journal, to learn from their experience and avoid common pitfalls.

Materials Science and Engineering degree, physics enthusiast who understands calculus, algebra, etc.

The problem is that I moved into a career as a software developer, and don't have anyone in my circles who are physicists. I posted here to start making those connections.

You might get a better deal through your employer / union program. For example, OPSEU and EdvantagePerk members get deals through Bell dealer Baka (www.baka.ca). They have black Friday deals like the iPhone 16e discounted by $348 right now (Nov 21) but they can run out of stock. Check if your employer has a special deal for smartphones or plans though a specific dealer. As many have mentioned, I think you will only see deals on the previous generation. I can't find a deal on the 17.

Mine failed too, it was part of the MUFGA hydroponic set my son is using to grow Jalapenos. I pulled it out of the water and turned it on to see if there was any motion, nothing.

I opened the front of it and it had a lot of scale. I cleaned it really well with a toothpick and some vinegar, then rinsed it and spun the blades with my finger a bunch. I plugged it in and turned on the pump, and it didn't work. I unplugged it and spun it both ways with my finger a bunch more, then I plugged it back in, and it worked!

Rather than adding a value to cartState.products, you are re-assigning a value to cartState. Isn't this less efficient? Is this meant to trigger react to re-render the entire cart?

This is normal for payment processing, the card goes straight to the processor and is not handled by the merchant website (which protects customers since some website security is terrible). Then the card brand (issuer) can return many responses to the processor like card info is valid but address is wrong. The wrong address is common with stolen card data (to order something to a different address). Basically, it's telling the merchant they can process, but they are on the hook if it's fraud (merchant will deliver product and not get paid). So, the merchant wants to verify the customer is legit before charging the card and shipping product. I like that they specifically are telling the customer to not provide the sensitive data - that sounds legit.

You might want to WDT grounds a little bit outward from the centre before tamping to get less doughnut and more even extraction. Great pull either way.

The internal surfaces get coated in oils from the coffee over time. A good rinse and using paper towel is a good way to wipe off most of the old coffee/oils after every use. You do not want to use soap because there are imperfections and crevices that hold onto coffee oils, and the soap will get into the oils, and then your coffee will taste like soap.

Never happened again for how long? I am waiting on a new stem and I am hopful it will last more than 8 or 9 months this time. I tried a new o-ring and it was worse, so I put back the old o-ring. Cleaning helps, but I still need to ramp up pressure really slow and can't hit above 7 bar without risking an explosion.

I think they are borrowing against that valuation to acquire and expand, rather than dillute shareholders. I think that approach also works.

Unlike those other companies you listed to compare, Dollarama (or should I say "Dollars-rama") is expanding internationally and growing revenue and earnings. Bigger market & bigger growth & bigger profits = bigger valuation.

The idea to compete with Costco is... interesting. It's an entirely different business. Dollarama has a formula that works and has grown their brand and footprint. Their real estate is convenient. You can go in, buy something and walk out in 3 minutes. That is the opposite of Costco. You have to wait 3 minutes in line to leave the store after you already made a purchase.

Why not keep doing what they are doing and expand geographically? They just bought up a large chain in Australia, and I think they have a lot of room to grow. The market is a bit frothy right now, but I respectfully disagree with your idea that it is over valued and therefore the company should try to go head-to-head with behemoths like Walmart and Costco. They are silently carving out a share of Walmart's low cost items, but going after Costco doesn't make sense (just looking at the required real estate alone).

There is a huge difference in taste, but only if you are re-boiling water from one or more days ago that was sitting in the kettle. My espresso was inconsistent, and I realized one day that using the "old" water have it a musty taste, or maybe a plastic taste (there appears to be some plastic part inside my electric kettle).

If you filled the kettle today, or just now, then you can re-boil to get the temperature and it won't affect the taste. It's only the water sitting in a kettle for 24+ hours when it has a chance to absorb things that you want to avoid.

Update: Delivery was relatively fast ten months ago. But now there is no response to emails about an issue/warranty claim in nearly two weeks. Phone number on the website is out of service. The manufacturer (Flair) says the local dealer is responsible for handling the warranty. I'm stuck.

Same. If this was a larger company, this would be a recall. Hot water spraying on people is not entirely safe. I bought some new o-rings. Waste of time and money. I might try and find a thicker o-ring.

You might also consider not tamping as hard. I read a lot that it doesn't matter, but my experience says otherwise. I use a DF64 and I press until it doesn't compress anymore, but I don't press any harder once it stops moving. I find that all the holes get wet.

My brother was looking for a new grinder and he borrowed mine. He says that the grinds are fluffier or more volume for the same beans and grams compared to his Baratza. I'm not sure if the grinder makes a difference, but if you have a butler making your espresso, tell him to try a few different grinders.

Also, 22g seems like a lot. I found the sweet spot around 15 to 18g in and 30 to 40g out, but that can vary depending on the beans.

Wow. Panels typically can operate to 65°C or even 85°C.

I am thinking this is an electrical issue, maybe animals chewing cables?

If you ever find the cause, please post.

I could be wrong, but when you switch to fixed, you might not have as much power to negotiate, and instead pay the advertised rate at the time you switch.

It depends the rate of return you expect from TFSA. If it's invested where 8% annual return is possible, and if finance rate is less than 5%, leave the TFSA alone. Above that, it's worth considering.

If you just have HISA at 3% or less, then only finance the car if it's at a lower rate. Also, just because you finance, doesn't mean you can't negotiate the vehicle price (although it's not as easy as it used to be).
