jml7c5··on Parallels confirms MacBook Neo can run Windows in a virtual machine
People keep claiming this, but my experience is that it's pretty similar. My mom's PC accidentally had only 4GB of RAM for the past 5 years (whoops), and we only noticed it a month ago because the cheap SSD was finally dying due to heavy swapping.
jml7c5··on 10% of Firefox crashes are caused by bitflips
As I understand it, DDR5's on-die ECC is mostly a cost-saving measure. Rather than fab perfect DRAM that never flips a bit in normal operation (expensive, lower yield), you can fab imperfect DRAM that is expected to sometimes flip, but then use internal ECC to silently correct it. The end result to the user is theoretically the same.

Because you can't track on-die ECC errors, you have no way of knowing how "faulty" a particular DRAM chip is. And if there's an uncorrected error, you can't detect it.

jml7c5··on Evolving descriptive text of mental content from human brain activity
As I understand it, the big challenge with brain electrodes is that because they are implanted in a big jiggly piece of jelly, they shift out of position and/or cause localized scarring. The practical effect is that the brain-electrode interface "wears out" after a while, and you can't get useful data. Has this been solved, or are implants still temporary?
jml7c5··on CXMT has been offering DDR4 chips at about half the prevailing market rate
It's easy to misread, but they're not arguing that. Note the "eventually" and "but right now".
jml7c5··on A solver for Semantle
Regarding Semantle, I found that Pimantle (https://semantle.pimanrul.es/) is a much more satisfying implementation to actually play. It provides a 2D visualization of guesses, which lets you see the clusters and lines of similarity more clearly.
jml7c5··on List animals until failure
Hmm, what's this one?

  var h = hash(guess);
  if (h==7182294905658010 || h==6344346315172974) { return "Adorable guess, but it's spelled “rosy”."; }
I'm guessing they're hashes for "<something> rosie" or "<something> rosey", but what?
jml7c5··on Android’s desktop interface leaks
Surprisingly, no. It's a "premium" feature these days.
jml7c5··on Ask HN: What recent UX changes make no sense to you?
Are you sure your browser isn't unloading tabs to save memory? I think Chrome enabled automatic unloading a while ago, and it's been standard on mobile browsers for ages.
jml7c5··on Apple introduces new AirTag with longer range and improved findability
Ironically, one of the reason Google's offerings are (were?) worse is because Google prioritized privacy and required pings from multiple phones to count a tracker as seen.
jml7c5··on Alex Honnold completes Taipei 101 skyscraper climb without ropes or safety net
Netflix has a stream with close-up cameras, as they were the ones who arranged the whole thing. Unfortunately the commentary and color grading are both terrible: https://www.netflix.com/watch/81987107

A YouTube search pulls up a stream filmed from the ground (a nearby building?) using a zoom lens: https://www.youtube.com/watch?v=Vzthkg2ti2Q

A little bit of humor for your Sunday reading.
jml7c5··on Phoenix: A modern X server written from scratch in Zig
It's a matter of designing and proprosing a protocol for it. X11's screensaver support was also a protocol extension.

There probably hasn't been much interest in it because screens can easily be powered off remotely, which was not the case in 1992.

jml7c5··on Super Mario 64 for the PS1
That link gives a 403 for me, presumably because fabiensanglard.net disabled hotlinking.

For others who run into the same problem, the file can be accessed via https://fabiensanglard.net/gebbdoom/index.html#:~:text=High%... . (I've highlighted the link to click.)

jml7c5··on Malware embedded into audio driver is silently recording from system mic
According to the vx-underground Twitter account, this is just Regin (which was first described in 2014): https://x.com/vxunderground/status/1995309917805179141

jml7c5··on Environment variables are a legacy mess: Let's dive deep into them
I'm surprised you say that. Iosevka is quite beloved as a monospace font. I use it for all my terminals, etc.

What sort of typing speed do you reach with it?
jml7c5··on The fix to the iPhone Antennagate in 2010 was 20 bytes
No, it was a real hardware issue, too. Applying a thin layer of kapton tape would reduce the drop by 8 dB.

jml7c5··on Discord customer service data breach leaks user info and scanned photo IDs
Per Discord's press release, it appears only a small subset of photo IDs were leaked:

>The unauthorized party also gained access to a small number of government ID images (e.g., driver’s license, passport) from users who had appealed an age determination.

It's not paywalled on my end. What message do you get?
jml7c5··on Vapor chamber tech keeps iPhone 17 Pro cool
Oppo uses these in some of their phones. They gave a factory tour to the "Know Art" Youtube channel, which made a good video on it: https://youtu.be/qAZ-q3KmDHM
jml7c5··on DeepSeek says its hit AI model cost just $294k to train
No, their calculation is based on a rental price of $2/hour.
jml7c5··on AMD claims Arm ISA doesn't offer efficiency advantage over x86
I think you may have misread that post. It said Linux was 5 hours, MacOS was 6.5 hours. There's a gap (Linux gets 77% the life of MacOS), but it's apparently not that significant.
jml7c5··on An attacker’s blunder gave us a look into their operations
You're supposed to spy on an organization's users and machines for the benefit of the organization that has contracted you. That's not what you're doing here. You've taken an adversarial relationship with your (potential) customer, acting to harm them.

Presumably legal, but morally gray.

jml7c5··on AMD claims Arm ISA doesn't offer efficiency advantage over x86
Other ARM laptops also have much worse SoCs, so it's not really apples-to-apples.
jml7c5··on I am giving up on Intel and have bought an AMD Ryzen 9950X3D
The big problem with ECC for me is that the sticks are so much more expensive. You'd expect ECC UDIMMs to have a price premium of just over 12.5% (because there are 9 chips instead of 8), but it's usually at least 100%. I don't mind paying reasonable premium for ECC, but paying double is too hard to swallow.
jml7c5··on Everything from 1991 Radio Shack ad I now do with my phone (2014)
We're on the verge of another consolidation, where laptops and tablets become dumb shells for phones. (Exceptions: "hardcore" gaming, software development, content creation.) But yes, there's less to capture.
jml7c5··on Stripe Launches L1 Blockchain: Tempo
Even if they were a fraud, at this point they've made enough money that they could be well capitalized. I'd love to know if they were a fraud (and I suspect they were), but I suspect they got past the "fake it until you make it" hurdle.

Fortunately the LA Times mini is still free, though the ad-wall can be long (15 seconds).

That's been an issue for years. Their swipe detection is completely broken.
