Check the reference client buglist, they got hit with a slowloris resource exhaustion combo. They fixed the resource exhaustion (kind of), they did not address the slowloris vulner…

> Where is the contradiction? I said that you can't verify the header until you have downloaded the entire block - meaning the time between a false header being submitted and the l…

lol, I marked every tenth led manually and counted twice - the number is correct, the marketplace is wrong. https://imgur.com/a/NqVXtDd https://www.mblock.com.tw/upload/Investor/ev…

> What are you even talking about here? 900KB takes a fraction of a second to transfer on a modest internet connection... You are assuming that there are no bad actors in the netwo…

> Where are you getting ideas like this? How fast do you think internet connections are? As fast as the packet source wants? The only way to defend against a slowloris DoS is by ac…

> I'm unclear on where you got 104x78. https://www.alibaba.com/product-detail/Hot-sale-small-pitch-... Module Res Size P1.923 104*78 200*150 I went ahead and counted... 128x96 (12,…

> Malicious actors can't give a bogus header, because you can verify the bogus header doesn't have enough PoW. Ok, I guess you don't know how verification works. Here are the 19 st…

Unless I'm misreading the page, it is claiming a resolution of 104x78. So that means 8,112 LEDs. The HDSP-2132 is made of 8 character elements, each element has a resolution of 5x7…

You are overlooking the disadvantage of not verifying the prior hash, which you can't do until you can verify hashMerkleRoot, which you can't do until you have collected the entire…

> What numbers are you basing that on? Bitcoin is 1.5KB/s. You know you can't verify an incomplete block, right? If you think you can just plow ahead after getting the first packet…

When you blow up the transaction limit you physically centralize the verification process. This is why you'd see miners gamble with sitting on a solved block and secretly beginning…

Yes, but they will be dealing with a currency that has mathematical guarantees - which changes things entirely. Imagine a scenario in which self driving cars are not only the norm,…

He was pretty upfront with the the possibility that his problems with rust were of his own making. The places he tried to leverage conditional compilation could be charitably descr…

Oh and it gets better: known bad data is still repeated, despite the poster being told why it was bad data - over a year ago. Pointing this out results in flagging, for reasons tha…

I've never seen an estimate that withstood any kind of scrutiny. I've seen estimates based on both fundamental misunderstanding of the function of mining, and wild assumptions rega…

It has been done a few times, but I doubt there would be any kind of market for it. https://hackaday.io/project/85515-redotmatrix Electroluminescent glass panels on the other hand.…

Yeah, the HDSP-2132 is a common display component in military hardware. I'm sure that readability figures into it (especially for NVGs), but so does hardiness. My hopes of an 80x24…

I wasn't kidding when I said "parroting". You are regurgitating a number derived from lazy thinking. https://news.ycombinator.com/item?id=21289486

lol, you seem to be forgetting every other system related to and directly supporting payment networks, clearinghouses, etc... oh, and all the regulatory frameworks. And the FED :)

It is odd, I've been involved in the cryptocurrency scene from the beginning, and I've seen the whole "Bitcoin kills Mother Gaia" talking point pop up every couple of years - but I…

Yeah, it isn't something that is feasible if you can't tailor the infrastructure to the underlying data. An SQL backend is about as generic as it gets, hence the poor results. Ente…

Yup, the most resource constrained form (PCRE2 would be the Cadillac-DoS-my-webapp option). I don't know how abnormal my problem is, but I've run into several cases where I needed …

It would be very nice if you could search based on file name, as you can with btdig.com. If you could somehow provide BRE without melting down, that would definitely put you way ah…

More an IBM archeology question: aside from the scattered projects to catalog specific product lines, are you aware of a more general effort? I've been pulling together a lot of th…

Funny, I was just over on ibm1130.org the other day - so the ALD diagram jumped right out. http://media.ibm1130.org/1132_Printer_ALD_Jun67.pdf
