Paying attention to feature distribution alignment (pun intended)

news.ycombinator.com Alex Shtoff 2025-10-31 21:02:12

Intro Yes, I’m making a joke of the tendency to put the words “attention” and “alignment” in any ML paper 😎. Now let’s see how this provocative title is related to our adventures in the land of polynomial features. The Legendre polynomial basis serverd us well in recent posts about polynomial features. One interesting thing we saw in the series is that its orthogonality is, in some sense informativeness. This is because it orthogonal bases produce features, and hence each basis function, in so

Trees on city streets cope with drought by drinking from leaky pipes

Urban trees lining streets fare better in dry spells than those in parks – now it seems that leaky water pipes are the reason for their endurance Trees on the streets of Montreal in Canada benefit from leaky pipes Catherine Zibo/Shutterstock Trees growing on city streets are more resistant to drought than those in parks because they are drinking from an unusual water source: leaky pipes.

gizmodo.com Sabina Graves 2025-11-14 06:00:00

The iconic Bad Wolf from Doctor Who has been playing a mysterious werewolf music teacher in Wednesday season two, and viewers have been left wondering what Billie Piper has up her flowy sleeves on the show. She, alongside whoever Lady Gaga will be playing when the Netflix show returns, remains another intriguing new addition to the show’s stacked ensemble. Piper’s turn as Isadora Capri marks a departure for the actress, whom director Tim Burton cast as a former child prodigy not too unlike Wedn

Installing a mini-split AC in a Brooklyn apartment

news.ycombinator.com Unknown 2025-11-27 03:06:03

Last year, 2024, we replaced four PTACs with a mini-split AC. I’ve been asked about it often enough (by neighbors, coworkers, friends) that I decided to write up the experience. Hopefully it’s useful for you, too. Overall this cost us about $40k, including the cost for closing up the PTAC holes. We’ll probably never make the money back on electricity cost savings, so the main benefits are that we have more quiet and more stable temperatures now and overall I’m glad that we did it.

I switched to this YouTube client and I’m never going back

androidauthority.com Unknown 2025-12-01 04:30:19

Nathan Drescher / Android Authority YouTube has been a part of my life since its early days in the late 00s. It’s no secret that today’s YouTube is a far cry from what it used to be. YouTube was free back then; free from subscriptions, free from ads, even free from terrible video suggestions. It was raw and real. Now when we open the app we’re bombarded with pop-ups and ads and the algorithm is awful at surfacing stuff we want to watch. So like many of you, I went searching for a replacement.

PHP 8.5 adds pipe operator

news.ycombinator.com Unknown 2025-12-12 09:13:43

PHP 8.5, due out November of this year, will bring with it another long-sought-after feature: the pipe operator ( |> ). It's a small feature with huge potential, yet it still took years to happen. What is a pipe operator? The pipe operator, spelled |> , is deceptively simple. It takes the value on its left side and passes it as the single argument to a function (or in PHP's case, callable ) on its right side: $result = "Hello World" |> strlen(...) // Is equivalent to $result = strlen("Hello W

NewPipe adds Android Auto support, bringing YouTube to your car screen

C. Scott Brown / Android Authority TL;DR Android Auto still doesn’t support the official YouTube app, but NewPipe can now fill that gap. The update lets you access playlists, history, and search from your car’s screen. Of course, you’ll only be able to watch while parked. Android Auto has always been pretty strict about what kinds of apps are allowed, but Google is starting to loosen up now, and NewPipe isn’t wasting any time. Thanks to the latest app update, the open-source YouTube alternat

How fast are Linux pipes anyway?

The challenge, and a slow first version # First of all, let’s start with measuring the performance of the fabled FizzBuzz program, following the rules laid down by the StackOverflow post: % ./fizzbuzz | pv >/dev/null 422GiB 0:00:16 [36.2GiB/s] pv is “pipe viewer”, a handy utility to measure the throughput of data flowing through a pipe.
