I don't think that's entirely clear. At least for cpus, less transistors in practice means you get rid of super-scalar architectures, and over-engineered microcode decoding and branch-prediction units. This leads to a modest reduc

For readability and conciseness you would most likely use a fold instead. The fold/or Foldable interface factors out the mechanism of the traversal of the relevant data-structure - list, vector, tree etc. Functional languages are an im

The business case may have been questionable, but the DAO was not prima facie a scam. It lost value and mission due to poor technical implementation.

The flash crash on GDAX? That was the non-decentralized code of a single exchange executing.

The same approach works well for forum discussions. One tab representing the forum, and child-tabs to track the comments section. For instance with HN, tabs provide quick navigatable references back to discussions that are relevant to my in

With a lhs vertical tree-style tab-manager, I'm at around 100-200 tabs. It works the same as an expandable chapter/section navigation metaphor, except I control the content and nesting.

There are various price-stable currency projects hosted on the eth/evm, backed by uncorrelated off-chain and on-chain collateral.

How so? HFT generally provides liquidity and is arguably a good thing, for people wanting to execute infrequent trades, on otherwise thin volume markets.

A counter-argument is that the Lightening work is a proprietary development outside of bitcoin core (lead by Blockstream) and the work is even patent-encumbered. They state the ip is for defensive purposes only - however that is questionabl

Nice job. Ethernet still isn't mainline for H3 and the linux kernel. I'm quite tempted to try this.

Trustzone is ARM's hardware access control. But I suspect AMD's PSP which incorporates an on-die ARM core rather than just implement the Trustzone ip, is doing a lot more. Reportedly it can manage DMA actions itself independently

Do you write the tests first - before the code - and while still exploring the domain? That's the guiding principle of TDD. Writing tests after the code has been written - to lock down behavior, quickly identify breakage, and support r

I would trust my own multi-threaded code too, but it requires much stronger knowledge of expected behaviors and code paths. I have had the misfortune to try and debug other's multithreaded code. Having a debugger connected to a product

Do you have proofs for your code that it can't deadlock or livelock? How strong are your claims - would you trust it in a life support system, or aircraft auto-pilot, or similar role?

Anyone know if it is an emulator, or an on-demand isa translator that operates at runtime? I wonder what the implications are for infringement.

No AMD run an on-die ARM co-processor, with dma access to memory and memory-mapped hardware such as ethernet controllers.

Another problem with large Java DI framesorks is that they obscure (with xml and weird conventions) a fundamentally simple operation. They also often resort to state-changing property-setters versus pure constructor args. Dependency injecti

The high-level meaning of a transaction is to send all the contents of an address. So if you only want to send partial payment, then you need two transactions - one to the foreign destination address and one back to yourself for the remaini

Not to mention, that such a discovery would be significant enough - that a protocol upgrade and fork would be inevitable, in order to protect addresses retroactively.

Could you explain what phase is? I understand haskell types, and I suspect Template haskell mostly works as an AST translator. A Google search on macros and phase, just turns up diet and bodybuilding preparation advice!
