Author here. I definite brought some old bias and history to this. At the time address space was more limited (32-bit) and kernel interfaces were O(n), but you're right that these issues are not as relevant today and the numbers don&#x

Author here. You're right in the sense that some forms of function coloring have good tradeoffs, though I think that's a watered down version of that original meaning. The point is that async/await tracks the wrong thing in t

I think the practitioner angle is what makes interesting. Too many BEAM advocacy posts are theoretical. I would push back on the "shared state with locks vs isolated state with message passing" framing. Both approaches model concu

I think systems end up mutable not because anyone chose it but because their tools make mutation the path of least resistance. Kafka succeeded not because "immutable logs are better" was a new idea but because it made the immutabl

Great survey. One thing I'd push further on your principle 2.3: the reason .context() chains work better than stack traces isn't just ergonomics, it's that they preserve causal information rather than mechanical information.

Agreed. There's quite a bit of room for optimization if your language design allows for it. Plus you have flexibility to make different tradeoffs as computer architectures and the cost of various operations change over time.

Judging by the content of the article I get the sense that he didn't choose that title. The gist seems to be that some previous wars helped focus our values and priorities of spending, and that recent wars lacked that focusing aspect.

As someone who has read countless resumes for the standard set of tech jobs, one page should be more than enough space. If you have a portfolio or can point to online projects you've worked on, then put a link in the resume so potentia

My comments were not a serious proposal. I was replying to a comment that lacked intellectual rigor and I proposed the opposite to point out some logical flaws. That said, cash transfers can help bring people out of poverty. A flat redistri

That depends on how the money is used. If it is just consumed, then sure, but if it's invested then it can be a renewable source of income. For instance, what if that money makes the difference in buying a car to commute to a better jo

That actually sounds like a worthwhile experiment. I doubt the 100 richest would be worse off or at a lack for opportunities to become rich again. And I bet giving $40K to a family of four (since you include children in your 300m count) in

It's not about banning or allowing, it's about counting the true costs and benefits of the trade, not the immediate effects. And you don't need philosopher kings to do this, just basic math and science. This particular articl

This is basically systems thinking, which was around before Scott Adams was born. It's okay for people to independently come to the same conclusion in a way that's meaningful to them. He's not claiming an invention, he's

This isn't bad for just Google. RSS aggregators were also getting the "everything's fine" message. I thought I had a bug in my aggregator until I went to the site and realized it was down.

Linode gives you 8 cores even at the low tier. Granted it's at lower priority but in practice I get way more than 1 core's worth of CPU.

As long as there's a switch to turn it off, you'll be just fine. Meanwhile millions of poorly monitored sites will be less vulnerable to attack at the cost of what I suspect will be relatively infrequent update snafus. All securit

I second 2001. Way ahead of its time in special effects and realism about space. The cinematography is Kubrik at his best. Plus it was the first film I ever felt was mind expanding.

Although, unexpectedly this is not due to a growth in the number of discouraged workers. It's not clear where they went. See http://www.motherjones.com/kevin-drum/2012/09/why-did-labor-...

This is math describing the effect not the cause, so the title is inaccurate and misleading.

I understand the googly eyed take on "the way of the future" of cars, but self-driving cars are going to be too impractical to become ubiquitous for much longer than 5-10. Maybe this all works great in metro areas with mild weather, but it'

I was interested in what webhooks are, but there was no link in the article. Aha! I thought to myself, I'll look it up on the internet, and behold there was webhooks.org, which I assume is its home. Going there I find no description of what

One from my workplace is "potato" as in "extremely low hanging fruit", features so easy and cheap to implement it's just like picking them up off the ground.

Agreed. And in the "what matters most" question they didn't include anything about making something useful for the customer, users, world, society, etc. Doing something meaningful is the most important factor to me.

That's surprisingly low. I would have expected more of a long tail of failures approaching 70%. Maybe more people than expected are lowering their target to ensure it's reached.

That's true but irrelevant. Military spending as a percentage of GDP has decreased significantly over the last 50 years. Government healthcare spending as a percentage of GDP has grown unabated over the same time and shows no signs of stopp
