magila··on NSF faces shake-up as officials abolish its 37 divisions
My experience is that discrimination in hiring is never openly advocated for obvious reasons. Instead you get what could be called "stochastic discrimination" where there is pressure to "increase diversity" without elaboration on how that should be achieved in the face of a not so diverse pool of qualified candidates.
magila··on The GPU, not the TPM, is the root of hardware DRM
Watermarking was a problem when Widevine L1 was first introduced. Pirates seem to have found a way to scrub the watermark from their releases. Either that or someone is burning a _lot_ of cash on playback hardware judging from the rate of 4K WEB-DL releases.

magila··on Block YouTube ads on AppleTV by decrypting and stripping ads from Profobuf
Source? I've seen a variety of claims about the revshare split on youtube, but I've never seen any official source of those numbers.
magila··on Cloudflare Registrar now supports .dev domains
I've never quite understood this idea that Cloudflare is an MITM. An MITM is by definition a covert intermediary. Cloudflare is a service provider that's deliberately employed by a site operator. If CF is a MITM then so is AWS, GCP, and every other CDN service provider.
magila··on Numbering Should Start at Zero
Great, now you've messed up all the other math that uses the modulo operator. The mathematical operators behave the way they do for well established reasons that long predate the invention of computers. It's going to be a tough sell to get everyone to adopt a wholesale refactoring of modulo arithmetic (and likely number theory in general) just for the "convenience" of one based indexing.
magila··on Numbering Should Start at Zero
In fact the vast majority of algorithms which involve doing computation on indexes beyond increment/decrement are naturally implemented with zero-based indexing. When using ones based indexing you end up having to convert to zero based, do the computation, then convert back to one based.

Another common example of this is circular buffers. Computing the bounded index from an arbitrary index is simply i % c with zero based indexing, but becomes (i-1) % c + 1 with one based indexing.

magila··on Asus Zenfone 10
I'd be willing to overlook a lot for a new Android phone with dimensions similar to the Sony Xperia XZ1 Compact. The market for small Android phones is extremely thin right now. There are only two phones which can run Android 13 and are less than 145 mm tall, and they're both less than a year away from EoL (Pixel 4a and Pixel 5).
magila··on XTS-210 25hp rotary engine; 1/5th size/weight of diesel piston engines
It's also not a turboprop if it's using a ducted fan. Chuck keeps using that word, I do not think it means what he thinks it means.
magila··on CATL has announced a new “condensed” battery with 500 Wh/kg
Eh, not really. Most "battery breakthrough!" press releases are about some new exotic chemistry while most mass produced battery improvements in the last 20 years have come from incremental improvements to existing chemistries and better packaging.
magila··on Lessons from America’s astonishing economic record
As someone with a chronic condition who has had to make many appointments with specialists over the years, 6-12 months is a gross exaggeration. IME the typical wait time to be seen by a specialist in the US is between 2 and 3 months. The worst I've seen is 4 months.
magila··on Direct evidence of the use of multiple drugs in Bronze Age from human hair test
Drug prohibition in the US was motivated more by hate for black/brown people than sky daddies.
magila··on Cigna saves millions by having its doctors reject claims without reading them
It still doesn't make sense. This whole ordeal has taken place over about 6 months. If anything, forcing me down the surgery route has pulled their costs forward in time, not pushed them back.
magila··on Cigna saves millions by having its doctors reject claims without reading them
I also have Crohn's and am going through this right now. Months of delays and denials for a new drug lead to two hospitalizations. I'm currently on TPN (IV nutrition) while I taper my Prednisone dose as low as possible prior to surgery.

The funny/sad thing is: between my hospitalizations, TPN and related home health care, and surgery, this is all going to cost my insurance far more than the drug they were denying would have. One would hope this provides them with motivation to better judge the necessity of treatments, but I'm not holding my breath.

magila··on Amazon to lay off 9,000 more workers after earlier cuts
I honestly can't tell if you're serious.
magila··on Linux Intel WiFi driver broken with 5&6GHz bands for longer than three years
Qualcomm's Atheros descended chips are generally the best bet for Linux support, especially for use in an AP. In other words you want a chip supported by the ath10k or ath11k driver depending on which generation of wifi you want. 10k = 802.11ac, 11k = 802.11ax.
magila··on Suing to protect right of incarcerated people to receive physical mail
My understanding is that most people opt to waive their right to a speedy trial after consulting with a lawyer. The reason is invoking the right guarantees the prosecutor will go hard in the paint pressing the maximum possible charges and generally making the defendant's life as unpleasant as possible.
magila··on Fix Intel CPU Throttling on Linux
If Intel wanted to use power/thermal limits for market segmentation they'd be locked down like the turbo frequency tables on non-K CPUs.
magila··on Mercedes-Benz previews its operating system MB.OS
Mercedes' reputation for reliability is mostly a legacy of the 60s and 70s. Their cars from that era were absurdly overbuilt, especially the diesel powered models. You will still find diesel MBs from the 70s on the road today, some of them having racked up 500k miles or more.
magila··on Eggspensive
In the US "pasture raised" is the key phrase to look for. That means what most people think when they read "free range". Neither "cage free" nor "free range" means much in the US.
magila··on Nintendo Will Pay Its Workers 10% More
RPGs were more expensive than other games due to a combination of high development cost, high cartridge cost (RPGs took a lot of ROM storage), and relatively small market (action games were more popular).
magila··on Math breakdown: Anime homing missiles
I always assumed the Sidewinder missile was named based on the snake's ability to sense prey by thermal radiation.
magila··on EPA proposes to strengthen air quality standards
It seems to me the complexity argument works in favor of cap-and-trade. While the global climate and global economy are both staggeringly complex systems, we can predict the former significantly more accurately than the latter. Thus it would be simpler to set the allowable emissions by policy and let the market work out the economic side.
magila··on Ask HN: What supplements do you take that have good scientific backing?
I think the biggest concern people have with cheap supplements is not so much efficacy as contamination with heavy metals and other nastiness. Especially with the vast majority of the raw ingredients being sourced from China. People are counting on the domestic distributer's testing to catch quality control issues before the product reaches consumers.
magila··on Gut epithelial barrier damage caused by dishwasher detergents and rinse aids
I suffered from chronic diarrhea for years which I attributed to Crohn's disease. This seemed obvious since diarrhea is a very common symptom of Crohn's, but its onset had been several years after I was diagnosed and prior to that I had tended more towards the opposite problem (constipation). I was thus always suspicious that the root cause lay elsewhere. After much experimenting I found that if I ran my dishwasher through an extra rinse cycle the diarrhea went away.

I tried many different detergents but never found one which didn't cause problems, so I've just continued to run an extra cycle. My GI doctor didn't really believe me when I told him. I wonder how many people are having their IBS/IBD symptoms exasperated by detergent residue left on their dishes.

magila··on US National Debt Tops $31T
The problem is markets are unpredictable and non-linear. It's not as simple as "we can rack up debt until it starts to become a problem then ease off". Events can (and historically often have) conspire to cause a country's debt situation to change from seemingly fine to disastrous on a radically shorter timeframe than one would expect assuming a linear response to increasing debt.
magila··on “When are we going to use this in our everyday life?” (2017)
Football players lift weights because it is known to be one of the more effective ways to build muscle strength. Do we have evidence to support the claim that learning calculus is particularly effective at improving general cognitive ability?
magila··on Zen4's AVX512 Teardown
The problem is the CPU itself isn't the one measuring voltage, it gets that information from the motherboard's VRM controller. The accuracy of the reported value can vary depending on the controller, how it's configured by the motherboard's firmware, and the physical circuit design.

That being said, with new motherboards generally using fully digital VRM controllers the reported value should be pretty close in most cases.

magila··on Hash collisions and exploitations – Instant MD5 collision
That page hasn't aged all that well. The prediction that applications would need to switch to a new hash function "every few years" hasn't panned out. The feared improved attacks on SHA-2 have failed to materialize. Applications that chose SHA-2 20 years ago are still quite secure today.

It seems we just weren't very good at designing hash functions in the 90s.

magila··on YouTube ads appear to be ramping up, with as many as 10 unskippable ads
No, which is the main reason why I don't subscribe.
