The Internet?
lmc··on PCs refuse to shut down after Microsoft patch
> my PC always comes back to the login screen immediately after I manually use "sleep" from the power menu. I have to to the sleep thing again. Has anyone else run into this issue?

Yes. By default moving the mouse or brushing the trackpad wakes the PC up... so when you have a fast machine it goes to sleep quicker than you can take your hand off the mouse. The solution is to turn off 'Allow device to wake' for the mouse in device manager. Well, that's been my experience anyway, there could be other causes I'm not aware of.

lmc··on Replit founder Amjad Masad isn’t afraid of Silicon Valley
Ha, fair points. But i still think you're wrong. Any group going around hitting people with slegehammers shouldn't be tolerated.
lmc··on Replit founder Amjad Masad isn’t afraid of Silicon Valley
Whatever. I suggest you take some time to reflect on your biases. What if a group used similar tactics to try and shut down e.g. gay friendly spaces?

Guess you didn't see the footage of them attacking the police with sledgehammers?

lmc··on Scientific production in the era of large language models [pdf]
My field now is Earth observation/geoinformatics and my recent connections are mostly academics and applied programmers. Also, mostly Europe-based and very few in the US. My feed is mainly about new papers, conferences, tools, webinars etc..

I used to do corporate software dev and my feed (and work) back then wasn't that interesting. I barely used the site.

In my field it's mostly in LinkedIn now.

lmc··on Linux is good now
"the real problem is a feeling that my computer isn't mine, that I am somehow renting this thing I put together with my own two hands from an AI corporation in Redmond."

I've installed Windows on all the PCs I've built for home and work over the last 20 years or so, until my latest in October. It was the ads in the lock screen that pushed me over the edge. Why should I pay for a license for that? Double-dipping fools. Am happily running Bazzite now.

lmc··on ACM Is Now Open Access
Cool, thanks for the perspective.
lmc··on ACM Is Now Open Access
Interesting, thanks for the reply. I wasn't aware grad students were so heavily involved in the review process, thought it was more postdocs.

Sorry, it's not obvious to me - how might payment for reviewers affect their decision making?

lmc··on “You should never build a CMS”
It didn't read as LLM-generated to me. And having some experience with CMS development, the article has plenty of substance. You can check previous blog articles from the same author far predating LLMs - here's one from 2018: https://www.sanity.io/blog/getting-started-with-sanity-as-a-.... The main difference i see with the OP article is it's a bit more emotive - probably a result of responding to a public trashing of their product.

The main point I'd like to raise in this comment though is that one of us is wrong - maybe me or you - and our internal LLM radar / vibe check is not as strong as we think. That worries me a bit. Probably LLM accusations are now becoming akin to the classic "You're a corporate shill!".

lmc··on Average DRAM price in USD over last 18 months
I just checked my go-to stores in Europe. Holy shit. I bought a 5200-speed 16GB DDR5 kit in October for 55 eur. Now it's selling for 240 eur. The 6000-speed model is now 390 eur.
lmc··on ESA Sentinel-1D delivers first high-resolution images
Typically you will get an image pair for an area every 6-12 days. The phase used in interferometry is massively affected by atmospheric conditions, which can vary a lot in this time, and are difficult to correct for. So, one pair is often not enough for this. But if you look at a bunch of pairs for that area over a longer time period, you might be able to correct for the atmospheric effects and get your differential height map. You can get more accurate elevation models 'out of the box' with different systems, e.g., the SRTM (one of the most well known publicly available global elevation maps) [1] was made with insar but 2 antennas on one craft, and Germany's TanDEM-X [2] is a pair of satellites flying in formation a few hundred meters apart, capturing the same area at the same time.

lmc··on ESA Sentinel-1D delivers first high-resolution images
What you can get in a single image are 5.5cm wavelength microwave backscatter - this means surface materials can be differentiated by looking at texture differences at that scale. So - tarmac vs a ploughed field, for example. There's 2 polarizations as well, so you can identify e.g. vegetated areas also, which scatter the signal in a different way.

A single image from Sentinel-1 won't give a height map directly, but a pair can using interferometry (InSAR), as the phase of the backscattered signal is also measured. With that you can derive something about the terrain. It's not super accurate though for absolute height maps.

And yes the signals pass through cloud and it works at night.

Ah yes, somehow I missed this :-S. Would edit my comment if I could.
lmc··on Researchers demonstrate centimetre-level positioning using smartwatches
The title is very misleading. The technique (RTK) depends on using a second receiver, not just a smartwatch on its own.
lmc··on Beliefs that are true for regular software but false when applied to AI
> With AI systems, almost all bad behaviour originates from the data that’s used to train them

Careful with this - even with perfect data (and training), models will still get stuff wrong.

lmc··on Study mode
> I'll personally attest: LLM's have been absolutely incredible to self learn new things post graduation.

How do you know when it's bullshitting you though?

lmc··on Study mode
I honestly don't know how they convince employees to make features like this - like, they must dogfood and see how wrong the models can be sometimes. Yet there's a conscious choice to not only release this to, but actively target, vast swathes of people that literally don't know better.
lmc··on TODOs aren't for doing
In my code these days, I have:

TODO

SHOULDDO

COULDDO

The TODOs generally don't make it to main, the others sometimes get picked up eventually.

lmc··on Map Features in OpenStreetMap with Computer Vision
> I will be happy to continue the discussion on what is a good prediction or not. I have mapped a lot of swimming pools myself and edited and removed a lot of (presumably) human contributed polygons that looked worse (too my eyes) than the predictions I approved to be uploaded.

Something else you need to be mindful of is that the mapbox imagery may be out of date, especially for the super zoomed in stuff (which comes from aerial flights). So e.g., a pool built 2 years ago might not show up.
