What about this is agile? >We can set up the assumption that today, each new application supporting API should be a cloud-ready application. By cloud-ready, we expect that it should have the following properties: The ability to adapt dyn

Yeah I understand why a product like Matlab which needs accuracy across a wide range of end use cases would need to consider things like this.

It's a 20min+ video about a guy soldering a NAND flash chip to a board designed to accept said NAND flash chip. Amazingly, Scotty manages to still make it interesting by giving you an unpolished view of his process; he documents his fa

I always try to relate these floating point issues back to real situations. Is there really a case where you would use a quadratic equation such as this and what kind of precision would you really be interested in? In the first example, the

I'd say that sometimes the raw economics works against you and it can be very difficult to change that. As an example take micro-payments, I'm sure hundreds of startups have tried to make it work but the economics don't stack

I'm not sure this is proving anything except that by developing an algorithm that filters out some predictions you can improve upon those predictions. And that is probably quite obvious given there are some users (presumably) on the si

This sort of proves that there is no such thing as "Wisdom of the Crowds". There seems to be a bit of a cult myth [1][2] about groups being able to "on average" outperform even the best individuals but that seems to be b

In 2017 they were claiming to be founded in 2015 [1] and didn't disclose that they were affiliated with financial companies. A few days ago [2] they were claiming to be founded in 2016 and disclosed that they were affiliated with finan

But unlike FDA approved drugs, registered dietitians and licensed physical therapists your service is not accredited and can't legally give the advice that it claims to give. As an example Ohio state law says that "only licensed d

Well not quite. The test net is actually a hybrid of proof of work and proof of stake [1]. Proof of work is used as the main decider in the case of a fork, however if long forks are seen then checkpoints validated by proof of stake are used

A dietitian is a different service though. Registered dietitians are trained, accredited professionals that can legally give you medical advice. This service will not give you medical advice.

On a positive note sharding technology does have great promise because of the problems that it can potentially solve. With Bitcoin you can only validate a transaction by having all of the unspent transactions in memory [1]. With a sharded s

Your terms state that "The services are not medical advice or treatment". If that is the case then this service is operating in a legal grey area where customers could be under the impression that medical advice is being given out

The section I particularly have a problem with is "How is the randomness for random sampling generated?" Everyone seems to think this is a solved problem but the reality is it is extremely difficult to solve. (The same problem exi

Typically you'd use a ceramic antenna on a product like this. What is the difference in radiated efficiency between this antenna and a ceramic one? I'm guessing there are other design considerations though, such as cost and circui

Even at 250k transactions per second that's over 20 billion transactions per day which seems unlikely. 1k transactions per second (100 million per day) is probably a closer ballpark figure for a company like Uber, given they only have

And it's relatively easy to prove intuitively. If you pick a random point in time, the time from that point to the point of finding the next block will be 10 minutes. That is globally true. The point will also be randomly distributed i

I completely agree but in this formulation of the problem the honest miners started at t=-10 so may have found the block before the dishonest miners in the timeframe from t=-10 to t=0.

by barbegal 9y ago
Craig Wright would be correct if not for the information that the dishonest miners found the "next" block. If anyone could have found the next block and the dishonest miners simply found a block at t=0 then the expected time for t

That allows an unscrupulous insurer to use a sybil attack to create insurance contracts with itself that it then pays out against emptying the smart contract pot.

by barbegal 9y ago
Smart contracts don't even work for insurance. Smart contracts require the insuring party to tie up capital to make sure they can satisfy the claim in the event that a claim is made. The problem is that each insurance smart contract ma

I don't necessarily buy this story because the facts don't really add up and there is no real evidence that this occurred. The source of the story is described to be one of Mark's friends "Here's how Mark described

Sadly this book is probably of limited use because it doesn't appear to cover getting BLE (Bluetooth low energy) to work with Android and iOS. Using BLE according to the standards is relatively simple if you have control over both ends

I don't understand how this network will work in practise. I can broadly understand the physical layer. There will be a big increase in bandwidth over other systems. More satellites and higher frequencies means more data in the system

I see what you're saying, I think my definition of EAV is probably not the correct one. In a real EAV where you have just one table and you only change data not the table structure you can only really query for a list of attributes. In

Maybe I haven't understood the article fully but I don't understand the use case here. Showing data in columns vs rows is purely about representation of the data as opposed to how it is stored in a database. The first query with o

To some degree yes. Many members of the Ethereum foundation have made large profits from the price of Ethereum going up. They have also taken a cut from the more scammy ICOs by acting as advisors (brand ambassadors). Furthermore the Ethereu

I would presume that something this low level is quite commercially sensitive so unfortunately we might never find out. As far as I can tell they have not released any technical information about how the original microcode update worked.
