ccooffee··on Don’t Talk to Police (2012) [video]
This was a really disappointing video. It is a 30 minute infomercial for a book that constantly says "what if <x>? well, you'll have to read the book".
ccooffee··on Google Is Shutting Down Album Archive
"The Last Question" by Asimov is a classic scifi short story that parallels this comment (presumably intentionally). The story is a short read and available for free on archive.org[0].

ccooffee··on Hackers can steal cryptographic keys by video-recording power LEDs 60 feet away
The "rolling shutter" graphic in this article is great and I appreciate the details provided.

> Activating a rolling shutter can upsample the sampling rate to collect roughly 60,000 measurements per second. By completely filling a frame with the power LED that’s present on or connected to a device while it performs cryptographic operations, the researchers exploited the rolling shutter, making it possible for an attacker to collect enough detail to deduce the secret key stored on a smart card, phone, or other device.

ccooffee··on Don't use custom CSS scrollbars
> Also in terms of accessibility, so long as they're doing CSS-only changes, and the bar is sized compliant and has proper focus states, assistive technology won't care.

Eh, it depends on your audience. My father has very poor eyesight. He doesn't use any assistive tools (e.g. screen readers or magnifiers), but he does need his computer-reading glasses. Accessibility isn't just ADA compliance and/or screen reader support.

ccooffee··on FBI: FISA Section 702 'absolutely critical' to spy on, err, protect Americans
> If you believe that there is never a need for law enforcement decisions to be made that cannot be revealed to the accused party, then that is a separate (and in my opinion, impractical/unreal) point.

Well, uhh, thanks for inviting a "genuine intellectual debate" and then out-of-hand dismissing any disagreements as "impractical/unreal".

We already have the grand jury which is a secret process and can deliver so called "sealed indictments" which prevents the indicted party from knowing they have been indicted. Grand juries have significant oversight and a long history of legal oversight.

FISA "courts", on the other hand, operate in an intentionally ill-defined legal space. To me, FISA courts are just as nonsense as the "unlawful enemy combatant" Bush-era policies. "This system is not _technically_ against the law because we built-in enough loopholes to prevent any actual legal oversight" should not be a valid argument for upholding a corrupt status-quo.

I don't accept the premise that some information is _too dangerous_ to be heard by a grand jury. We already have legal processes to limit exposure, including many trial processes that are done without the jury being present.

ccooffee··on Two men got jobs at Amazon just to steal copies of Zelda
If your goal is to acquire an unreleased video game, they may be a very trustworthy person. But probably not the type of trustworthy you want to manage a store.

The "steal from your employer" angle isn't so great, but "working around the system to accomplish your goals" is an ethos widely lauded here on HN. If the person had placed a pre-order through Amazon and found a way to mark their order as "delivered" when walking out the door with it, I'd have no problem with it.

ccooffee··on Two men got jobs at Amazon just to steal copies of Zelda
> Years from now, the extra few days he got to play won't matter at all.

While I agree in general with the sentiment that time is fungible, I think the story about getting a job to steal a video game might make the whole experience more memorable. "I found a video game on the street and got to play it early" is one thing, but "I got a job so I could steal a pre-release copy of the game" reflects a lot about the character of the person.

The early days playing the game won't matter, but the days spent PRIOR to playing the game will be a treasured memory.

ccooffee··on Had a call with Reddit to discuss pricing
Someone at Reddit has since restored the linked post[0]. I think the content is unchanged, but it may have been subtly edited while it was "[removed]".

> Finally, to ensure that all regulatory requirements are met in the handling of mature content, we will be limiting access to sexually explicit content for third-party apps starting on July 5, 2023, except for moderation needs.

Reddit really buried "no nsfw outside official reddit apps" (from the end of your first link). Didn't Tumblr do something similar and lose a significant fraction of its userbase and revenues?

ccooffee··on Had a call with Reddit to discuss pricing
> 50 million requests costs $12,000

I've never worked on a web platform like Reddit, nor with any per-request priced APIs. Reddit's charge of $0.00024 per request still looks like it is _significantly_ above what their own costs are.

Wasn't Reddit's pay-for-API-access announcement originally phrased as a desire to claw back some of the value that LLMs have found in Reddit data? I don't understand how per-request API pricing actually accomplishes that. (I was vaguely anticipating Reddit's API pricing to have some sort of expensive "firehose" endpoint for OpenAI/Google/Meta/etc to pull from.)

It looks like they're instead going to squeeze out all third-party apps instead. I don't think this bodes well for Reddit's future.

ccooffee··on HBO Max new Captcha system
No idea. I'm not offering solutions, merely complaints that the current approach of "answer a question that is hard for computers and easy for humans" removes disabled people from many places on the internet.
ccooffee··on Purdue Pharma can protect Sackler owners in opioid bankruptcy, court rules
I think cases like this are outside the scope of the Corruption Perceptions Index. At least, your wikipedia link describes it as: (*emphasis* mine)

> The Corruption Perceptions Index (CPI) is an index which ranks countries "by their perceived levels of *public sector corruption*, as determined by expert assessments and opinion surveys.

From skimming the court order, it seems that this is an instance of private sector corruption. In 2004, the Purdue board (which included at least 6 Sackler family members) created a policy to indemnify the board, executives, and some others against any claims/suits/etc. There was a narrow carve-out where a court decision that someone acted in "bad faith" would void the indemnification.

ccooffee··on Lyft’s plan to take control of its maps and its future
> By late 2019, Lorimer and Justin Moore, then the head of engineering, were ready to form a team to “do the impossible” — create a home-grown mapping system.

THE IMPOSSIBLE: A "home-grown" mapping system built on OpenStreetMaps?

Lyft seems to really lack any imagination if _that_ was considered impossible.

ccooffee··on HBO Max new Captcha system
I'm not sure I agree that it is "a bad thing".

The current internet culture seems quite happy to slap captchas all over the place. When they first rolled out, captchas were predominantly a barrier for "write access" (e.g. make an account, complete a sale, write a comment). But companies like Cloudflare have been putting captchas everywhere for mere read access.

Because Captchas are designed to be easy for ("normal") people but hard for machines, they often disallow disabled users. I'm a ("mostly normal") 35 year old, but I _really_ struggle with captchas. I despise when Cloudflare tosses a captcha challenge before loading a page, as I'll need to spend 3-5 minutes of effort to figure out which tiny pictures have a stoplight, motorcycle, or crosswalk.

Will someone come up with a less restrictive anti-bot solution? I hope so. But even if not, I'm not sure it matters. According to comments in this thread (and elsewhere on the internet about the HBO Max captcha), many of these captchas are _already_ terrible at excluding robots. We're using captchas to exclude low-sophistication robots and disabled users. Seems wrong.

ccooffee··on HBO Max new Captcha system
Good, I can't wait for the CAPTCHA to go away. They're accessibility nightmares _by design_.
ccooffee··on Comparing iPhone 13 vs. iPhone 14 for Astrophotography

ccooffee··on UMD Study Finds Brain Connectivity, Memory Improves in Adults After Walking
From the study[0][1-pdf], the exercise routine was walking on a treadmill with adjustable gradient. The objective was to keep participants in the 50-60% heart rate range for 30 minutes, which was done by altering the gradient and speed. Including the 10 minutes warm-up and 10 minutes cool-down, this gave 4x weekly workouts of 50 minutes to the mostly 75+ year old patients.

Given that the participants were screened to be low-exercise individuals beforehand, this gives some evidence that "exercise more" is a reasonable treatment for low-activity seniors experiencing cognitive decline.

Because it stood out as weird to me, I want to remark that the study's participation requirements explicitly filtered out depressed patients, day-to-day impaired patients, and anyone left-handed (???).

ccooffee··on Ice loss from Greenland and Antarctica hits new record
> our dummy ancestors were around 50 million years ago

While true, this vague statement may be misinterpreted by readers. Per Wikipedia[0], about 55 million years ago is the first fossil evidence of any apes. The 'homo' genus, which is what I'd consider "our dummy ancestors", doesn't appear until 2 million years ago (and anatomically modern humans 300,000 years ago).

ccooffee··on SFPD obtained live access to business camera network in anticipation of protest
SCOTUS has repeatedly considered the "chilling effect" of government policies to be sufficient to strike down government policies. Here's a long article from MTSU about the history of the "chilling effect" on First Amendment jurisprudence: https://mtsu.edu/first-amendment/article/897/chilling-effect

tl;dr: having a "chilling effect" is, according to SCOTUS, often (but not always) the same thing as "actively suppressing" freedom of speech.

ccooffee··on Meta AI announces Massive Multilingual Speech code, models for 1000+ languages
Very fair point. I've never seen it used, but SignWriting is already in the Unicode standard[0] (at U+1D800 - U+1DAAF).

I suspect Meta/Facebook doesn't have a lot of content to work off of. I've only been able to find community-generated examples of SignWriting on the official website[1], and none of those seem to be using Unicode characters. MMS is an audio-to-text tool, so it seems unlikely that it can be trivially expanded to take in visual data (pictures of text or video of ASL being performed).

I suspect the process of turning viewed ASL into SignWriting text will be very difficult to automate. I would not be surprised if such a project would either use a different textual encoding or directly translate out to English (which also sounds terribly hard, but these LLM advances recently have surprised me).

Thanks for sharing. This is a well-written and well-presented account of how mass-produced woodprint paintings show noticeable change between early- and later-printings.
ccooffee··on Meta AI announces Massive Multilingual Speech code, models for 1000+ languages
American Sign Language, ISO-693-3 code 'ase', does not have a formal written or spoken grammar. Obviously, the list of MMS supported languages[0] does not include support for 'ase' because MMS is a tool for spoken language and, as an intermediate state, written language.

ccooffee··on Breakthrough deal to prevent Colorado River from drying up
> I forget the # and am not willing to look it up right now.

I gotchu.

1944's "UTILIZATION OF WATERS OF THE COLORADO AND TIJUANA RIVERS AND OF THE RIO GRANDE" treaty between the US and Mexico established the "International Boundary and Water Commission" (IBWC). The text of the 1944 treaty is available from IBWC's website[0][1].

According to the text of the 1944 treaty (article 10 deals with the Colorado River), Mexico is entitled to at minimum 1.5 million acre-feet of water per year from the Colorado River, and in wet years is entitled to 1.7 million acre-feet of water.

Based on the submitted article, which says "3m acre-feet of water is expected to be conserved over the next three years". If that comes down to 1m acre-feet per year, that's 2/3 of the quantity of water guaranteed to Mexico.

ccooffee··on The end of the accounting search
This makes intuitive sense, but isn't an idea I'd thought of before. Are there any resources you'd point to as an intro to terminal/CLI/etc UX (especially any that contrast against GUI instincts)?
ccooffee··on Ask HN: I have 176 logins/accounts. How many do you have?
On its own, the information in those private accounts is probably not interesting. I used to use the "few sites get a unique and secret password, but most reuse the same 10 character one" ruleset, but I became worried about how much data could be aggregated about me. By re-using the same password, I felt like I gave a simple test that attackers could use to definitively confirm "user XYZ on site ABC is the same as ccooffee".

I'm now firmly in the "everything gets a unique password" camp. There are 4 important passwords I type myself, but everything else is in a password vault.

ccooffee··on Tell HN: Today Is Global Accessibility Awareness Day
I worked for a US government contractor. According to US law, any software we sold to the federal government has to make accessibility a primary concern. The company never paid more than lip service to the idea. (The closest we ever got was showing that a particular screen reader _could_ make sense of a very very small part of the application.)

Eventually the company was sued by a former user who had been fired from a US government job for low performance when using the company's software. The company settled out of court for some amount of money, but never changed the company policies. To my knowledge, that company still doesn't take accessibility seriously despite the law and despite having settled at least one court case about it.

Perhaps the UK is able to enforce their requirements in a way to actually cause changes in behavior, but it wasn't the case in the US in the 2010s.

ccooffee··on ChatGPT app for iOS
The problem also occurs when searching for any low-ranking results in the iOS store, regardless of getting the exact name correct. A friend released a crossword game, and when searching the exact name of the app, it still comes up as the seventh result behind one ad and five other (much more popular) crossword apps with different names.
ccooffee··on Scientists regenerate hair cells that enable hearing
From the article on PNAS[0]:

> Despite the progress in our approach to achieve HC regeneration in the adult cochlea in vitro and in vivo, major challenges remain before potential clinical applications. First, regenerated HCs need to be terminally differentiated and fully mature, and to be located in the sensory epithelial region such that their stereocilia contact the tectorial membrane to mediate the mechanoelectrical transduction, as well as be able to survive long term. The current regenerated HC-like cells are immature and the time frame we used is not ideal to determine their long-term survival. One potential reason for the lack of terminal differentiation is the continuous Atoh1 expression mediated by adenovirus, which is known to impact HC maturation and is detrimental to HC survival (9, 56). Future studies to express Atoh1 transiently in the reprogrammed SCs could address the issue. Second, the surgical procedure of “cochleostomy” in the adult cochlea severely damages the microenvironment of the cochlea including extensive OHC death around the injection site. Future studies using an alternative delivery vehicle with a minimally invasive surgical procedure such as an AAV with round window injection could significantly improve HC regeneration efficiency without causing trauma to the inner ear. Third, major efforts should be made to identify/create new AAVs or novel delivery vehicles such as nanoparticles capable of targeting adult cochlear SCs for reprogramming. Finally, the restoration of hearing in adult deaf animal models significantly and reliably by HC regeneration will elevate the field of HC regeneration to a clinically relevant stage.

It sounds like the authors have found a more effective way to trigger generation of immature Hair Cells than was already known, but they're several large steps away from "restoration of hearing in adult deaf animal models".

However, the submitted article (from hms.harvard.edu) summarizes the findings as:

> [Authors] reported creating a drug-like cocktail of different molecules that successfully regenerated hair cells in a mouse model by reprogramming a series of genetic pathways within the inner ear.

While it's not outright false, the "successfully regenerated" isn't the way I'd interpret the PNAS paper. Perhaps I misread the paper.

ccooffee··on A mutation turned ants into parasites in one generation
I disagree. The question,

> Has science ever observed speciation via natural selection amongst a sexually reproducing cohort?

posits a world where we can iteratively ask-and-answer questions if scientists are paying attention to speciation. The fossil record provides many many snapshots of different beings, from which we can infer speciation. By seeing the split _as it happens_, we can test hypotheses.

ccooffee··on Lyft CEO tells employees they must return to the office
To me, Lyft's entire brand is "not as good as Uber, but not as shitty to drivers as Uber". Maybe they've done something else innovative, but their PR is so vapid that I've never noticed. Your "maybe ok if your company doesn't foresee any big changes coming" is exactly what I expect of Lyft.
