I don't see the similarity. Would you please substantiate your claim? Going to the article you cited, the ultimate magic appears to be the use of macros. Defining composable (mini-)languages that are appropriate for a given domain is indeed

Similar, but not the same. California / Cascadia / Mormonland form different entities on his map, but are all lumped under San Francisco Federal Reserve District.

If the hardware access is taken care by the hypervisor, doesn't this imply the hypervisor supports the functionality of device drivers, i.e. the hypervisor has become the OS? Granted, it may delegate the device driver work to a some VM, in

I can only hope that from now on reviewers of Mr. Musk cars will turn their mobile phones in data recording stations and even the field. Broder was taken by surprise; there is little precedent for the kind of irrelevant spin he was the subj

An interesting question is why do developers prefer runtime extensibility over compile time extensibility? Runtime extensibility trusts whatever happens to come on the wire, compile time extensibility explicitly whitelists the exact set of

Duh, blocks are evaluated in leftmost order. This is neither news, nor particularly profound in any number of popular curly brace languages. Rewritten with curly braces, so it's recognizable by most Blub programmers out there: { { pri

Edward talks about the monad laws, especially the associativity one. But that is kind of simplistic, because the domain over which the laws apply can be shaped quite complexly, leading, for example, to IO or State being "monads". I fail t

Add auto-complete to the command line and everyone will start using long form without the need to beg. Imperfectly remembering the flag spelling is a rather large annoyance, short flags avoid this problem at the cost of crypticism, autocomp

Out of technical curiosity, would it be reasonable to remove YAML from the source tree and check for the lack of exploit via "find $APP_ROOT -name "*.rb" | xargs grep YAML"?

FRP is super nice, but no magic. I found that it makes it natural to decompose the codebase in model/view/controller and encourages an explicit state machine for updating the model. At the same time, a time-varying value is a plain old obse

The core issue is that the system relies on bargaining instead of truth. But we can't make judgements of the system in abstract. The system is the sum of the actions of its participants. In that sense, it is perfectly fine to call out indiv

Indeed words have a meaning. If you issue a statement that "the defendant is charged with crimes that carry a maximum sentence of 35 years", then you inherently quantify the gravity of the defendant acts as a 35 year jail time crime. If, in

Given how the rest of the society works, I'd be not surprised that "incompetent" really means "poorly connected" and that the whole system is just a $1.5 million racket to get a "well connected" lawyer to grease your case.

There is one detail: she never added, in public, "I'm seeking X years". She always kept talking about the maximum penalty. The ball is in her court and Linus is right to call her backpedaling a lie.

Perhaps this may sound harsh, but if you handle large amounts of money and are informed that your software stack allows arbitrary code execution then: You pull off the plug ASAP. Better have customers unable to use the service for one day t

You add tainting propagation to every method in the system that handles tainted user input. Hopefully, this will encourage you to untaint the user input ASAP and build native objects out of it. Now, of course, if you take untainted strings

The APIs are exactly the same. One is explicit, reading its signature is enough to understand what it does, the other one is implicit, requiring reading the method body. The implicit version readability mass increases fast as it makes furth

I'm assuming that emitting "movzx edi, byte [PTR]" is using x86 as the target, thus retargeting for ARM will likely require a complete rewrite of the brainf#ck jit. In that sense retargeting is hard. But I may be wrong! I am looking for a f

TL;DR DynASM is a toned down JIT compiler which directly generates target assembly instead of a more abstract IL. Retargeting and optimizations will be hard. I'm looking forward the next installment, where (hopefully!) one generates target

What about spec the "why", then engage with the team to figure out the "what", then let the team figure out the "how" by themselves. Believe it or not, the PM is not the only one with problem-solving skills on the team to tackle the mapping

As long as there is a mechanical transformation from one style to another, this is not abstracting, is merely shifting the syntax. You do introduce more named test points, but you risk of creating too many tests at a too small granularity,
