Strange to see a lock-free ring buffer without seeing mention of LMAX/Martin Thompson's Java Disruptor (https://github.com/LMAX-Exchange/disruptor)

Weird to see this here! I've used CoralBlocks in the low-latency trading domain previously. Highly recommend. The API is kind, they're very responsive, and the latency is exceptional (and comes with all the basics like thread pinning built-in for convenience)

The Dacia Sandero starts at around 13k in Europe and by all means a pretty good car. I have a friend who bought one new and told me it has been very reliable.
The Dacia Sandero unfortunately gets a 2 star Euro NCAP rating (which is typical for Dacia cars). Not something I personally would feel safe putting my family into!
WeaselNo7 commented on Ask HN: What's the most creative 'useless' program you've ever written? · Posted by u/reverseCh
A year or so ago, my son needed a tool for making really simple minecraft plans. All the drawing tools out there he could find were overly complex or weren't 'quite right' for him, so I took the opportunity to learn some web and javascript stuff and made this: https://draw.pixelweasel.com/
One outstanding 'todo' was textures!
Then I wanted to make ASCII art automatically from any picture, so I played around and made this: http://ascii.pixelweasel.com/ (again, playing with javascript)
Super cool. Love the interface, was not expecting to be thrown back a few decades!
On mobile, I tried recording to /c/PepTalk, but after recording my voice, none of the buttons ('save', 'play' or 'stop') did anything. So I wasn't sure if it had actually uploaded.
Then when I went back to the /c/PepTalk channel to check I had a popup saying something like 'failed to fetch waves' (sorry, I don't recall the exact error message!).
I'll keep an eye on this ongoing though, as I adore the concept.
That's really interesting to hear; as a generalist, I've had a hard time finding positions that aren't super spiky!
Same boat here. Do we need a hiring market specifically for generalists?
WeaselNo7 commented on WeWork chases new financing as cash crunch looms ft.com/content/f29ecc58-e... · Posted by u/paulsutter
It seems like the value that they are offering is just outsourced-office-management then. Am I wrong in thinking that? It's hard for me to parse what WeWork was "trying" to become. A real estate company that manages offices? An office management company that also does real estate?
That's a big part of it. But their scale and presence also means they get to do things that have been invaluable for us, like being able to book meeting rooms in and have access to other WeWork premises with low effort.

Spreadsheets are phenomenally flexible, but they obviously don't scale well or behave nicely with source control.
I work at Anaplan, and the most common way that our biggest customers discover us is when they've been bitten by spreadsheets as they've scaled, and now they have users emailing spreadsheets around and someone with a full time job collating them.
We've modelled the product around the flexibility, but rigor and scale on top of it.

if you can program, you can read maths (understanding its purpose is a different issue)
this formula defines a function U(x). This means that it gives a recipe that takes a number x and produces a number U(x). The recipe depends on an already prepared set of ingredients: a set of numbers x1, x2, ..., xt, k, and another function f. Now, given a number x, to compute U(x), you first compute all the numbers f(xi)-k*|x-xi|, and then you pick the smallest one. This smallest value is then U(x).
The graph below the formula displays its interpretation. The graph of the function f is the red curve, the points (xi, f(xi)) are the black dots, and U(x) is in green.
Wonderful, thank you!
