FWIW I didnt take the blog as a dunk on CUDA, just as an impressive outcome from the blog writer in Mojo. It's awesome to see this on Hopper - if it makes it go faster thats awesome.
So there is highly efficient matrix transpose in Mojo
All three Mojo kernels outperform their CUDA counterparts, with the naive and swizzle kernels showing significant improvements (20.6% and 14.8% faster respectively), while the final optimized kernel achieves essentially identical performance (slightly better by 4.14 GB/s).
The "flag" here seemed innapropriate given that its true this implementation is indeed faster, and certainly the final iteration could be improved on further. It wasn't wrong to say 14% or even 20%.
Users of the site only have one control available: the flag. There's no way to object only to the title but not to the post, and despite what you say that title hit the trifecta: not the original title, factually incorrect, and clickbait. So I'm not that surprised it got flagged (even if I did not flag it myself).
Email the mods at hn@ycombinator.com. There's a chance they'll remove the flag and re-up the post.
I do find it amusing that all comments are focused on the US. There are hundreds of countries around the world were TV stations are black boxes and presidential / prime ministerial hopefuls have no platform to express themselves. Having access to a platform that can promote and answer content as users are searching for answers on them (at least how it reads on face value) seems incredibly important. I do however agree that transparency around who gets access to the platform is critical for user trust.
Well consider the number of 3rd party services that would shut or require a significant amount of development to get back online as a result of google shutting down:
Thanks for the question. We try to make the transaction process as fast as possible. As long as you ship your device the same day you do your swap, you can get your new device as fast as 2 days later. USPS Priority Mail shipping is used both ways and is free of charge. The time also varies based on location.
Have you read the sites context ? It's not a pyramid scheme. Lets recall what a pyramid scheme is expressly defined as
"A pyramid scheme is a non-sustainable business model that involves promising participants payment or services, primarily for enrolling other people into the scheme, rather than supplying any real investment or sale of products or services to the public"
Now lets read what the site does
"We buy your products for Honey. You buy anything using Honey." - all the products you buy using honey are new according to the site. There isn't a second hand market place on this site - so there is not any supply issues here. The supply is the company sending out products based on the current market value of the products interpreted into their model.
You sell your product, they will give you virtual currency in order to lock you into their ecosystem and then you buy a new product based on that honey value. Please explain to me, in lay terms, how that explanation is equal to the definition of pyramid scheme above ?
Frankly speaking, dealing with morons from craigslist is becoming a pain in the ass and if the value is not that different and these guys can give me the convenience, delivery and remove headaches - great. It comes down to their pricing vs. others in the market (gazelle and so on)
>You sell your product, they will give you virtual currency in order to lock you into their ecosystem and then you buy a new product based on that honey value. Please explain to me, in lay terms, how that explanation is equal to the definition of pyramid scheme above ?
Thank you for pointing out that you don't use their currency to buy the products they purchased from their other customers (though it makes me wonder what they're doing with them then).
But let me put it this way: There are three ways they can offer you more for your products in fake currency than in real currency. 1) They expect users to hold an ever-increasing amount of their currency in their accounts and not spend it immediately. If too many users tried to spend their currency all at once they would go out of business and you would lose your money; it's a pyramid scheme. 2) They give you $440 instead of $400 for your iPhone, but then a new product that would cost $400 on Amazon costs $440 in their currency. It's not a real discount. 3) They take less as profit than Amazon, even on top of Amazon's economies of scale, which is almost certainly not sustainable.
I'm terribly sorry. But your continued use of "pyramid scheme" is just wrong.
1) "they expect users to hold an ever-increasing amount of their currency in their accounts and not spend it immediately."
> Where does it say that ? Unfortunately no where. And who wants to hold their currency ? Use case: I want a new phone. I accept the offer from swapidy for X currency and then buy a new iphone at X currency. At what point do I want to hold my currency ? No, I want a new phone and if their pricing makes sense I transact. Thats it.
2) "too many users tried to spend their currency all at once they would go out of business and you would lose your money;"
> At what point would you loose your money ? The currency is valid and you can purchase an item. They send you that item. I am assuming your inference is that they do not stock any of the items they sell and I am unclear where you draw that inference from ? Please let me know if you have some sort of information that I do not other than what is illustrated on the site. If you transact and sell your phone, you send it to them and I assume they will subsequently sell that. You purchase a new phone and they send you that new phone. There is obviously the requirement for inventory and stock and so on. Thats a business and cost inventory issue, nothing else. If the company fails, you become a creditor - like when any company fails. It's a trust issue and up to them to ensure that its trust worthy.
3) "it's a pyramid scheme."
> No, its not. Refer above and please refer to Wikipedia or other sources to learn about pyramid schemes.
4) " They give you $440 instead of $400 for your iPhone, but then a new product that would cost $400 on Amazon costs $440 in their currency. It's not a real discount. "
> Amazon is not a fluctuating pricing market like ebay or other such services. You will receive a standardized cost on Amazon for a extended period of time whereas this site infers you will receive the current daily market rate or close enough. This is the difference and therefore ultimately the difference in the pricing mechanism. If you want cash, transact at some other market and see if the pricing differential is more advantageous than what they offer. Some items will be cheaper and some will not be - don't tell me they actually want to run a site that makes money ? The use of virtual currency is to lock a user into their service and there is nothing wrong with that if you want to accept their buy offer which is more than you would receive elsewhere. No one is forcing your hand to transact.
5) "They take less as profit than Amazon"
> How do you know what profit they take ? Feel free to let me know.
