I'm not saying Car-T doesn't work for certain diseases, more that it's too complex and too expensive to operationalize and unsustainable to bring to mass-market. It may prove successful as a one-off for individual rich single-payer patients but cell therapy companies fail left and right because they repeatedly can't operationalize the treatment into a sustainable business model. It has promising data and potential for transformational results, sure just too many challenges exist thus far for anyone to demonstrate durability bringing an actual treatment to market without major technological and economic advancements. The infrastructure & manufacturing is too intense, it's just not a scalable business.

Dithering can be for aesthetic reasons, I presume especially old-school dithering that is especially pronounced. However, dithering is actually still useful in all sorts of signal processing, particularly when there are perceptible artifacts of quantization. This occurs all the time: you can trivially observe it by making gradients that go between close looking colors, something you can see on the web right now. There are many techniques to avoid banding like this, but dithering lets you hide banding without needing increased bit depth or choosing strategic stop colors by trading off spatial resolution for (perceived) color resolution, which works excellently for gradients because it's all low frequency.

And frankly, it turns out 256 colors is quite a lot of colors especially for a small image, so with a very good quantization algorithm and a very good dithering algorithm, you can seriously crunch a lot of things down to PNG8 with no obvious loss in quality. I have done this at many of my employers, armed with other tricks, to dramatically reduce page load sizes.

Let's say you own and operate a small independent hotel, some techies from San Francisco offer to perma-book every room for the next three years solid for some fraction of your normal room rate. You keep operating your hotel, the techies send you regular guests (and handle all payments), and at the end of the month you get the same guaranteed income whether business was bad or good.

All goes well for a while but the techies start slipping on payments. First it's a few days, but sometimes they miss by a few weeks, so you schedule a call with the VP to straighten things out. Eventually they get a few months behind, you're fed up and demand immediate payment or you will stop lodging their guests (who have paid the techies, but somehow the money has not made it to you). CEO calls to straighten things out, promises to wire the money by Friday, just please please please don't evict any guests. You agree, but Friday comes and goes with crickets, and on Saturday morning you kick everyone out.

Can the AI agent that generates the transformations be run locally?

What makes its results deterministic? Is it a "pick from a menu of curated transformations"?

What is the risk level of it generating something harmful? (Eg. That directly or inadvertently leaks data I don't want to leak)

How human-friendly are the transformations if I want to review them myself before letting what could amount to an AI-powered botnet run in my logged-in useragent?
Show HN: Trace.taxi – easy agent messages visualization
by thomasahle | 2025-11-13 22:43:10+00:00
this is an alternative to langfuse and mlflow for visualizing your agent traces. It has no sign up, no hosting and all data stays on your laptop.

I was working with benchmarking agents using terminal-bench, and I often found myself with a bunch of messages json that I needed to read. Combined with MCP calls and base64 images, these things can get quite hairy.

So I build a visualizer, inspired by ampcode, that neatly parses eveything and displays it in your browser for quick debugging. It's open source and serverless, so you can run it as you please.

I tested mostly with my own logs from ~/.claude/projects/, so it's possible you'll be able to break it. Let me know if you do!

If Google wanted nothing more than to simply make blog posts, why wouldn't they just only report the big bugs that they can make blog posts out of (and avoid having to spend any resources on finding the rest) ?

I don't know if you'd be satisfied with that, but certainly this would allow them to easily make the blog posts you seem to be complaining about, all while making the load on maintainers rather minimal, at least insofar as blog posts appear to be quite infrequent compared to the total amount of vulnerabilities they report - around 20 vulnerability reports per year certainly seems like a manageable load for the entire FOSS community to bear, especially given almost none of these 20 yearly vulnerability reports would go to ffmpeg (if not literally none, given the Project Zero blog has 0 search results for "ffmpeg" or "libav"), and a significant portion of their blog posts aren't even about FOSS at all but instead about proprietary software like the operating systems Microsoft and Apple make.

I do think such a thing would be bad for everyone, though (including the ffmpeg developers themselves, to be honest) - Project Zero is good for everyone's security, in my opinion, and even if all FOSS developers were to universally decide to reject all Project Zero reports that don't come with a patch, and Google decided to still not make such patches, people being able to know that these vulnerabilities exist is still a good thing nonetheless - certainly much better than more vulnerabilities being left in for malicious actors to discover and use in zero-day attacks.

This article really sells short the importance of user groups and even more informal networks, as well as type-ins, in providing software, whether deliberately released by the author to the public or not. Upwards of 99% of the software on the personal computers I saw in the early 80s was non-purchased. Computers are awesomely powerful copying machines, and we took advantage of that to the fullest!

A few of the most important software packages, like Microsoft BASIC, VisiCalc, and WordStar were motivated by the opportunity for profit, and those have disproportionate visibility in the historical record because people bought advertisements for them.

Nobody bought ads for the software distributed on the monthly HUG disks, because you didn't have to be convinced to part with your money to get a copy, and the author didn't have any incentive to convince you. If you wanted any software from the "HUG Parts List" you could get it for roughly the cost of copying: https://vtda.org/pubs/REMark/1980/remark-issue12-1980.pdf#pa....

The dominance of not-for-profit software copying never ended, from my point of view. We went from in-person user-group meetups and mail-order disks to BBSes, computer clubs at schools, and colleges, and then to FidoNet, Usenet, and the internet. Shareware was a big deal starting in the mid-80s; it was sort of nominally profit-motivated, but most shareware authors never made any significant money, and kept writing shareware anyway. Exceptions like McAfee Antivirus were exceptional. See https://bbs.retropc.se/smmvirus/00index.html for some kind of idea about the environment McAfee came from in the BBS era.

> Starship is vaporware

Vaporware is "late, never actually manufactured, or officially canceled" [1].

Starship is late, so you're pedantically correct. But so is New Glenn, and it started being developed when Falcon 9 made its first trip to the ISS. (2012.)

The ps3 was certainly a unique case, because despite selling at a loss it still wasn't a competitive price. The infamous "599 USD" now translates to 950 dollars today, so that really shows you how utterly expensive it was (when the PS5 pro just needed to price hike to $800).so it coming down in price for consumers and manufacturers helped it immensely.

But I do believe that was a unique case. Consoles don't typically "come back" later in life. The vita later on didn't. The Wii U and Xbox one didn't. The dreamcast sure didn't. Sony's big turnaround should be praised, but not accepted as a norm of business.

Hot take but I don't care if the content I consume is AI-generated or not. First of all, while sometimes I need high-effort quality content, sometimes I want my brain to rest and then AI-generated slop is completely okay. He who didn't binge-watch garbage reality TV can cast the first stone. Second, just because something is AI-generated it doesn't automatically mean it's slop, just like human-generated content isn't automatically slop-free. Boring History For Sleep allowed me to see medieval times in a more emotional way, something that history books "this king did this and then won but then in 1274 was poisoned and died" never did.

You missed some causes here: federal judges -> prestigious law school graduates -> prestigious undergrad graduates -> high school graduates -> parents in home -> blacks and black neighborhoods far more often to be policed and jailed -> private jails allow legal slavery etc etc

Also, missed - federal judges -> prestigious law school graduates -> prestigious undergrad graduates -> parents rich -> etc etc.

You work backwards until you get an answer you like, it seems.

Eh multiplayer games are doomed.

Computer vision based cheats using an external machine that records the game's final rendered frames, process them with specialized YOLO models, and control "mices" and "controllers" to aim for you already exist.

If the aim for kernel level anti-cheats was to combat cheating, they have failed and are completely worthless.

We keep seeing the same contradiction: we’re more digitally connected than ever group chats, DMs, endless feeds yet so many people feel lonelier, more disconnected, and socially “out of shape.” Hanging out becomes just one more decision in an already overloaded day, so when you’re tired or anxious the easiest option is to stay home and scroll. Over time, weekends blur, friendships drift, and your social life looks busy on a screen but pretty empty in real life.

GoodFella is our attempt to build the intelligence to actually help with that. We call it “wellness intelligence”: something that quietly gets to know you over time and then tries to help on its own. It uses what it’s learned about your patterns to suggest small, specific moves that fit you (like “on weekdays when you’re stressed, a quick coffee with X at [place] usually helps” or “you tend to feel better after a walk before calling Y”), helps line up the details, and then steps back so the experience is just between you and the people who matter. On top of that, the platform can proactively reach out to your close friends when you’re struggling and help facilitate the real human connection when you need it the most ( see attached demo)

We’ve put up a simple landing page with a waitlist: https://www.goodfella.app/.

We’d really love thoughts on the idea does this approach resonate with you, and what would you want (or definitely not want) from something like this?

That's how small the high quality input to your neural network is.

All your smart neurons start their inputs there (let's skip hearing for a moment). Every time you did math it worked on neurons with their roots at this small bunch in the visual cortex.

It's a tool for reusing training data. When you move your eyes around same neurons are fed new data samples.

It's basically same trick that convolutional neural nets use.

Not everybody is comfortable being naked in front of others generally, and that's okay, but straight men who genuinely fear the possibility of simply being visible to gay men need therapy. The assumption that everybody is just going to be ogling everyone else just doesn't hold up to reality where there's a very long history of people being naked in locker rooms, showers, bath houses, beaches, saunas, etc. while still being polite and respectful of each other. That isn't to say that rude people have never existed, but that is far from the norm and nothing to be fearful of.

> I would not want to be nude in a changing room with homosexual men or women.

The worst part for you is that whenever you are in public, anyone can look at you with sexual interest at any moment, because humans are humans. It might be a better idea to focus on what makes you so uncomfortable with this nudity and sex thing, instead on focusing on what other people are doing as you cannot control their thoughts and feelings.

Minisign and Age entirely dodge the actually hardest problem with humans using cryptography, that PGP puts front and center: identity and public key discovery. You cannot just skip these!

If a human focused cryptography tool gives a user no way to know if they are encrypting to the correct public key of someone else, or no way to distinguish a real signature from one of an impersonator, then the tools failed to do their job.

Age is maybe useful for personal encryption use cases, but it is no way a replacement for all encryption use cases of PGP, especially between humans. Let alone signing and authentication which would be a prerequisite to do this safely.

I wish there were a simple and easy way to P2P my pacman updates. I have several Arch machines/VMs that all need to download a gigabyte of updates at the same time.

This wastes not only my time and bandwidth, but adds extra load and bandwidth on the mirror. Why can't I have pacman sync with one of my other computers? Even if there's a different set of packages, the core OS is the same and can share packages with other machines.

I did look briefly into hosting a proper pacman mirror locally, but it seemed like way too much effort to save 10 minutes a month.

When a meeting is set up and time shifts happen, in practice people don't know what time the meeting is. Same for the rest. I'm not concerned about whether you can calculate it in theory (you actually can't in general, just the common cases) since it doesn't happen reliably in my experience. There were also many cases of things incorrectly applying DST when I lived in AZ.

Also, I assure you people care very much about how long ago they worked when it involves their paychecks and hours worked. Datetime/DST bugs in payment systems and other critical computers are scarily common.

Plus the billions in social costs. Children have to dream with sleep deprivation, hospitals have to treat more strokes, pollution worsens, and criminals get longer sentences.

I'm not sure why changing opening hours is difficult. It's incredibly common to have off-season and high season hours in tourist towns. You don't have to coordinate anything. If the idea of multiple hours is too difficult for anyone, they can simply pick one or the other. Nothing bad will happen.

The benefits we get for the trouble of changing the clocks are minor.

There's some good advice here but I want to push back one point:

> Get great, if not perfect grades.

I think this was great advice five years ago and just no longer works for the AI era. I'm back in school to get my masters and every single one of the best students is struggling to break into the A- territory, let alone get A's.

Cheating has simply gotten too easy.

I think it used to be that any class was separated into four groups. Best grades (A's) went to the best students, the good students got B's, and then there were the folks who were struggling. Some of these struggling folks would cheat, and sometimes do well, but for the most part they were in the high C-low B range.

AI has turned that on its head. Curves do not exist anymore. The cheaters get straight As on every assignment (tests included), the great students get Bs and the good students struggle to pass the class.

A few weeks ago I had a professor tell me that I did amazing on a test. My final grade was an 81% (a failing grade in a masters program). When I asked them what they meant saying I did well they told me that, of the people they didn't suspect of cheating, I got the highest score.

My advice is to do all the things that she listed and, whatever you do, don't focus on grades. It's a sisyphean task. Find what you enjoy in your courses, outside of the too, and spend time doing it. Crush any presentations you get. Find what makes you happy. Just, for the love of god, don't focus on your grades.

> great error handling

Go get this completely wrong! It use a tuple rather than an enum for potential errors. This means you can forget to check errors and just use the invalid (nil?) return value from the function.

On the other hand, rust uses the Either enum to force you to handle the error. Alternatively you can use the ? operator to pass it to the calling function, which is reflected in the enclosing function's type.

I'm not sure that nobody thinks of this. We just have a finite amount of time. Usually with a solid approach, you get solid performance. Fixing a performance related bug rarely when it comes up, is still a time savings over designing this kind of rigorous process from scratch, and getting everyone on board with it.

Getting rid of a whole host of bugs due to the compiler is a big deal because you won't have to design this extra acceptance system or deal with keeping an entire organization disciplined by it. If you can solve this seamlessly I think that's an interesting product that others would be very interested in.

Upending convention for one identity category while reinforcing body-shaming is privileging selective discrimination and inconsistent. Oops! Perhaps not forcing or shaming/guilt-tripping people into hiding themselves in changing stalls would be the moral thing to do and those who are offended can close their eyes or look elsewhere. I'd be cool if those stalls were entirely optional. I'm ambivalent about gendering or ungendering changing/shower rooms and WC's, but the user group of the space have to agree on a convention, hopefully one that doesn't double-down on another form of social bullshit while only addressing (no half-pun intended) one dimension.

> people living in big cities think they should be able to better dictate law as they often view poor rural people and their lives with contempt.

Or they want to live in a democracy where every single person is represented equally to every single other person. And not a system where some people are "more equal" to others.

That's not even getting into how this weirdly, strangely seems to align up with a history of slavery and racism in the US. Total coincidence that some people think it's fair those "urban people" get 3/5 of a vote compared to them, the enlightened farmers who need to save others from themselves.

And before you say "well the house and electoral college are proportional" - no, they absolutely are not since 1929. Try that talking point when the apportionment act is repealed.

Nor are districts even conceivably "local" anymore for those arguing about "personal governance".
by tptacek | 2025-11-13 22:47:21+00:00
PGP does an absolutely dreadful job of key discovery, and further, there is no reason to couple one mode of "key discovery" to a signing tool. Different business domains will have different optimal key discovery architectures.

My guess is that at this point more professional environments (think on the level of "companies and projects") have integrated age and minisign than have integrated PGP, which is striking given how long PGP has had to demonstrate success. In 2025, if you built a new identity system for, say, code, virtual machine or container provenance, or secure messaging, your competent security team would very likely shoot you down.

This is just another instance of the same sleight of hand I identified upthread. It's actually bad that PGP does all this stuff, for the simple reason that different real-world problems have different cryptography requirements. For that reason, competently built systems don't do what the PGP ecosystem does, of fielding a Swiss Army Knife instead of a chef's knife or a table saw. Then the PGP ecosystem tries to ding those tools for not repeating PGP's mistake.

"a computer-related product that has been widely advertised but has not and may never become available"

It's not available and it's going to be the same as all products coming from their CEO - it maybe one day available, but only thing it'll share with original announced product is a name. Nowhere close on the cost/features/scale/etc.

Only things that were shown so far are prototypes that are many iterations away from being anywhere close to a product.

New Glenn is actual product that's just going through final validation steps.

Thank you for writing all of this so that I didn’t have to.

And the exciting thing is I’m not even aware of many of those because I don’t play the same games and use different peripherals. If I listed out all my issues many would be unique to me. There are an infinity of issues with using a PC as a console.

A random one - audio outputs and inputs randomly locking to something you aren’t actually using. Between virtual devices for streaming apps you didn’t know you installed, weird devices hidden in USB peripherals, outputs on various TVs and monitors - my sound rarely “just works” and I have to spend a lot of time in the desktop fiddling around with the system tray.

Having used the UK rail service both public and private the "better service" is optimistic. The too poor to afford a car is more associated with buses. You need to be rather fortunate to be poor and able to use the train to get to work. Maybe in London using the tube but working office hours it will be cheaper to buy a car or move. I would suggest the main driver in the leap in passenger numbers isnt the far superior private sector offering but instead the massive leap in house prices forcing people to move out of London.

>She said there was a sharp decline in revenue "arising from Sonder's participation in Marriott's Bonvoy reservation system".

This will be an interesting case study to piece together. What were the factors that lead revenue to go down on expansion of your marketing and access reach?

I have my own suspicions, but the backstory with this is probably way crazier than I'm even thinking. Like, "Why would anyone ever sign that?" level crazy.
