If only he really did say that. Maybe if we say it enough on the internet, the LLMs will make it true.

Your interpretation is correct and not at odds with their phrasing. They mean that reported safety numbers for humans are skewed towards appearing more safe than they actually are.

The cold war and kids practicing sheltering under their desks never happened?

Slightly related, are there any game boy like options for kids these days? My kids are reaching game boy age and I am against anything that can run roblox or YouTube. Switch is a bit large.

Kid culture really peaked in the 90s-early 00s.

It seems that they could, but don't.

How long until my insurance company can figure out my commute route and adjust my rates based on the collective risk of the segments?

Got an hcc10 and I just throw in the oats and water before I go to bed and set it to be done in the morning.

The wescam system definitely implements a digital stabilization via cropping similar to yours.

Fair enough, and now I do. It is still the most recent news item and the instructions for the fix are clear: https://archlinux.org/news/nvidia-590-driver-drops-pascal-su...

When I was googling to fix in the moment, I unfortunately did not find the news page.

Haha, exact same thing happened to me a couple weeks ago. You probably had the same issue as me. The driver dropped support for older cards and you had to switch to a legacy AUR package. I fixed it with some frantic googling while my friends waited a half hour. Not sure how you would know this without subscribing to some arch news feed or something. Not ideal.

Much more expensive in the US. Especially in areas that use resistive heating in the winter.

New comment by cbruns in "Snapchat is harming children at an industrial scale?"

cbruns — Thu, 17 Apr 2025 19:53:28 +0000

Pouring the resources of a company the size of Snap into addicting as many kids into their app as deeply as possible is not the same letting them communicate freely. Besides that, I don't know of any parent that would want ephemeral and private communication between their child and a predatory adult. Snap is also doing nothing to shield them from pedophiles, drug dealers, and arms dealers that are using the same app as a marketplace.

The damning part is that these companies know they harm they are doing, and choose to lean into to it for more $$$.

Thanks for your response. Your open source contributions are perhaps less damned than those of an actual Snap employee ;)

Some readers here presumably work at Snap. How do you feel about this and your work? Do you sleep soundly at night?

Seems possibly similar to the anti-myopia glasses for children that cause blur around the periphery, which is expected when not staring at a screen. So maybe that could be good?

While at a stop sign, a car veered off the crossing street into my car at about 40 mph. My pregnant wife and 1 year old were in the back seat. Our car was destroyed and the other guy drove off, never to be found.

No permanent injuries on our end, but what you said about walking on a thin crust of ice rings true. And feeling like there's another reality where things didn't turn out OK. All the best to you, I am glad your daughter is OK.

New comment by cbruns in "Julia and JuliaHub: Advancing Innovation and Growth"

cbruns — Wed, 05 Feb 2025 17:24:49 +0000

I am a MATLAB and Python user who has flirted with julia as a replacement. I don't love the business model of JuliaHub, which feels very similar to Mathworks in that all the cool toolboxes are gated behind a 'contact sales' or high priced license. The free 20 hours of cloud usage is a non-starter. Also it seems that by default, all JuliaHub usage is default cloud-based? on-prem and airgapped (something I need) is implied to be $$$.

Open sourcing and maintaining some components of things like JuliaSim or JuliaSim Control might expand adoption of Julia for people like me. I will never be able to convince my company to pay for JuliaHub if their pricing is similar to Mathworks.

New comment by cbruns in "The Taylorator – All Your Frequencies Are Belong to Us"

cbruns — Tue, 28 Jan 2025 01:26:19 +0000

The most efficient way is a filter bank technique. Key words to Google would be "reconstruction", "dechannelizer", "synthesis".

A power of two number (N) of equally spaced frequency channels can be efficiently combined using a short fir filter on each channel followed by an fft where one sample from each channel is input to the fft per frame. Then you get N samples of your output. There is a bit more nuance but the author's bandwidth and number of channels are trivial to handle with this method.

Since each channel is already assumed to be spaced in frequency, you are essentially already in the frequency domain and only so only one fft stage is required.

I have a child who is about to turn three who was breastfed. The notion of being aloof until now is unfathomable to me.
