You're ignoring the effect of the medium itself.

Education requires sustained engagement. Books are conducive to that kind of deep engagement with the material. It requires perseverance, an ability to sit with a topic at the expense of indulging all the cheap distractions that may be available to them (the internet furnishes these gladly and easily). TikTok and bite-sized social media is certainly not conducive to that. The train never leaves the station. Social media's very form consists of feeding the impulsive indulgence of distraction. It only produces superficiality and trains the user's attention span to contract, or to never develop in the first place.

Gamifying learning is a fool's errand. Children are easily distracted, because they haven't yet learned discipline. They need something to counteract these urges, like removing the tempting distraction, an environment that is saturated with relationships and habits that enable good behavior and pursuits, or the threat of punishment for straying from good behavior.

No not at all, it is done completely differently though.

Before when I was talking about the needle in a haystack problem which is the biggest weakness of the modern big data era.

So to give a really concrete example imagine you need to meet a source clandestinely in the past it’s lots of sneaking around doing surveillance detection routes and meeting in hotel rooms and things like that. Those days are completely dead. You stand out immediately.

Instead you’re looking to have very normal and plausible reasons to be in the same space together while remaining in a large crowd and not having contact usually outside of that.

So imagine you and I both get season tickets to the local sports team and we go there to watch a game just as regular fans and we find a way to communicate in that crowd.

Even the best data analysis / ML algorithms are only ever going to see two people going to a sports match every few weeks. There’s nothing interesting about either one of them that stands out.

It’s just a very different way of doing business basically but hopefully that’s an illustrative example to show you what I mean.

Great, let's do that when the negative externalities of cars are properly priced into their usage. This is the number one reason that's causing such sentiments, and rightly so. Expecting people to approach it differently before that is fixed is unrealistic. Currently, cars are subsidized to an absurdly higher level than public transit. That's the status quo. A change of that status quo means moving car subsidies to public transit subsidies, unless you raise taxes, which will make the exact same people defensive and hate you.

Look at Greater Tokyo. 37 million people - and they have everything. Pedestrians, cyclists, cars, taxies, buses, surface roads, expressways, trains, subways, monorails, high speed rail, ferries, etc. All interconnected, and all being used to capacity at rush hour every day. It's absolutely insane, but every time I visit I'm in awe at how easy it is to get around (albeit unpleasant at times).

There's a huge spectrum between dense city center and suburbia; at present, I do consider my area to be "walkable", but it's not anywhere close to a dense city and there sure aren't "corporate HQs" anywhere nearby.

I do value having several gyms and restaurants (and friends) within just a short bike ride from my current house; and since one of the gyms I visit regularly is in the shopping mall, if I have an interest to cook something specific, I can buy whatever's necessary with like 5-10 mins of extra overhead.

And I do go to the local convenience store more or less daily anyway, if only for some snack, produce or fresh bread. There's a shop in each direction wherever I'd want to go, so the only way for me _not_ to inadvertently pass by one would be if I didn't leave my home at all entire day.

I'm not discounting anyone's general preference for country life, it's perfectly valid; I'm just saying that some of the things you're saying seem overexaggerated.

She's just one nutjob figurehead.

I'm talking about the larger number of people who supported, and are seemingly still supporting the deranged figureheads. When you examine the details, none of these policies actually benefit America - and doubly so with the incompetent execution. Yet as the results become increasingly undeniable, the supporters are twisting themselves into ever-tighter knots trying to stay in that fictional universe.

Great question! I’m one of the collaborators on the project. Right now, the MCP server doesn’t “correct” hallucinations itself, but it enforces a strict tool interface: the LLM can only call valid ROS topics, services, or actions that actually exist and that are explicitly exposed as safe to use. This information is provided through the MCP, so if the model hallucinates a command, the call simply fails gracefully rather than executing something unintended.

For more advanced use cases, we’re also thinking about adding validation layers and safety constraints before execution — so the MCP acts not just as a bridge, but also as a safeguard.

> this means that the trip was made easier by car, not that a trip was impossible and is now possible.

If someone chooses to not make a trip then I count it as impossible. I could walk across the North Pole to Europe, but I think everyone would agree when I say the trip is impossible anyway despite that.

> This does not work in populated areas with high demand. (This is incredibly well studied)

You absolute can and I disagree with the studies. Now I will agree that building 50 layers of highway bridges needed is not a reasonable thing to do, but it still a solvable engineering challenge if we wanted to put the money into it.

I really wanted to like Tarsnap and gave it a good hard look for my backup needs. Ultimately my problem was that there's no way for me to gauge how much the service will cost me. Going just by the amount of data in my home dir, it would be cost prohibitive to upload to Tarsnap. The site does assure me that thanks to compression and deduplication, the actual cost will be far less than I might estimate, which is great! But also, as far as I can tell there's no way to have the client give me an estimate of "here's how much data you actually have once the secret sauce is applied". So while the dedup and compression might make the costs far more reasonable, I won't actually know until I pay to store some data. Which means I might find that suddenly I owe Colin a lot of money if the size savings aren't very big due to my data not being very amenable to those measures. That's not a risk I'm willing to take, so ultimately I pursued other options.

Fwiw.. I have a "normal" private git server over SSH, but for public projects, it copies merges into blessed branches to public, read-only repos accessible via HTTPS. Here's an example:

https://www.bi6.us/GI/B/

I sort of punted on receiving patches and merge requests because most of the projects I'm distributing in this way aren't really open source, but "published source" and there's a small community of people who use them. The people who use the public, read-only repos know how to generate patches and distribute them via email or (in one case) uploading them to an S3 bucket.

Anyway... your mileage may vary, but it's worked reasonably well for a small community. Not sure I would recommend it for a huge open source project.

Out of the box, I agree. I've got my feed well-curated at this point such that I get very little of that type of garbage pushed my way. I recently viewed the YouTube main page in an incognito window and, good lord, the default experience is an absolute cesspool of AI-generated nonsense, ragebait, and straight-up spam.

> The more remote your living is, the more everyone else is subsidizing your existence.

This is an uncritical viewpoint, you're simply describing a society. It doesn't matter where you live, you're soaking up the labor and capital of the wider net of people. That's what it is to have a civilization, and ours is so deeply interconnected that all relationships are inherently reciprocal. The trivially measurable flow of money doesn't say anything of substance as it's a second order abstraction, only that the mechanisms and pipelines by which money move are situated in cities. It's not urban labor and urban resources that builds, maintains and operates that infrastructure or the social fabric that it serves and is served by.

> It's one thing for the people who already live there or genuinely need to live out there, it's another thing for people to choose to live out there for "personal reasons".

On the contrary, the negative health effects of cities are empirically measurable[1][2][3]. We should be striving at all times as human beings to move past having them at all, and should look to building towards healthier, lower density living and encourage it for anyone who is capable of doing so. We cannot fall into the trap of building, encouraging and valuing objectively worse living conditions in the name of efficiency, the entire point of this whole system is to lead better lives, not to make the numbers go up.

> requiring internet access to access local media

Good news! You can whitelist exceptions by IP/subnet

Go into Plex Settings, then Settings > Network (show advanced). Scroll down to "List of IP addresses and networks that are allowed without auth"

"Comma separated list of IP addresses or IP/netmask entries for networks that are allowed to access Plex Media Server without logging in. When the server is signed out and this value is set, only localhost and addresses on this list will be allowed."

Put your local subnet and netmask into that (e.g. "192.168.1.1/255.255.255.0") and you should be all good

FYI, I also have "Secure Connections" set to "Preferred", but I don't know if that makes a difference for this or not

Yeah I know schools like that exist, I just doubt that they are anywhere near the majority.

The games I have been to recently have a medic of some kind, the coaches, band/drumline director, police officers for security, plus a bunch of teachers doing other things. They may not be getting paid extra to do it, but they're still employees and a portion of their time is being used for the game.

First, a disclaimer. I’ve worked with Ankur, and he is a brilliant, super-organized, and methodical engineer.

Personally, I’m on the other end of the spectrum. I’m still up for a good organization, and I do my own simplified version of PARA[1] + Johnny Decimal.[2] However, I’m beginning to tend more and more towards how Steph Ango uses Obsidian[3] while still maintaining simplicity and ways to walk out when needed. I’m either listing a list of files based on keywords, either via the Open command or the Search feature. I, sometimes, use a Universal Search Extension for Obsidian, but I can live without it.

My final thoughts, especially on the UX, are that, eventually, when it becomes commonplace to run a local LLM, I should most likely be just using Spotlight/Alfred or something to open, search, link, and all of that while I just keep adding contents into their own ”boxes” that I have categorized at the gate while filing the documents/content.

I’m not sure if I can even explain what I’m thinking, but the above is a precursor to what I believe will happen soon enough.

Show HN: Browser extensions for my privacy-first temporary email service
by gkoos | 2025-09-10 14:59:15+00:00
I previously shared a simple disposable email tool focused on privacy (no tracking, no signup). https://nullmail.cc

Now I've released extensions for Chrome and Firefox to make it easier to use: - Generate a new address in one click from the toolbar - Manage temp mailboxes from the extension (until they expire) - No need to open the site each time (although the extension does open it) - Same approach: minimal, privacy-first, open-source backend

Firefox Add-on: https://addons.mozilla.org/en-GB/firefox/addon/nullmail-exte...

Chrome Extension: https://chromewebstore.google.com/detail/nullmail-extension/...

Curious to hear from others - do you prefer temp mail in the browser toolbar, or sticking to the website?

I'm with you, like I said it's not okay. It just isn't rape, as I understand the word. Extortion sure. Despicable sure. Illegal I don't know but it definitely seems to me like it should be.

I just don't see any reason to use the word rape for it. I think people want to use it because it sounds bad and they want to express that this person is a bad person, but on the other hand it devalues the word in a way.

Like did he rape someone or did he "rape" someone? Any time I hear about some celebrity rape thing that's what I wonder. Is the guy a actual rapist or are people just putting the rape label on a less severe (although possibly still despicable) act?

Honestly I am not sure the point you are trying to make. In what world is that at all ok?

You know damn well that if they raided a largely white work site people would be up in arms (people are already up in arms, but who would be up in arms would be different). But clearly its fine since they are not white, perfectly normal to detain people before making sure they should be detained.

The US has over the past ~40 made a system that celebrates big time winners, both of stocks, housing, etc.

There are no big time winners without big time losers.

What you are discovering now are fundamental consequences of inequality. It is not just for housing, but for all aspects of the society.

Either we celebrate the winners in an in-equal society, or we instantiate an equal society.

You can't have your cake and eat it too - neither can the losers of the Florida housing market.

I don't see it as a status thing - I see it as a convenience thing.

If I want to fork your code and contribute back, that means I need to be on the same system as you.

There's a bunch of Gnome projects which require me to sign up to their specific git hosting service before I can contribute.

On most git servers, I have to fork in order to send a PR, which often means I have to create a fork on their system - which means I need to set up something to replicate it to my local machine.

It's all friction.

I'd love to see a project on (for example) GitHub and then clone it to my GitLab, work on it there, and send a PR from GL to GH.

I was about to suggest employing PingCastle to audit domains for weak default configurations such as these, but apparently, PingCastle still doesn't complain about RC4 enabled Kerberos accounts - only about DES. So now is a good opportunity to check any domains you are responsible for by hand.

Note that since the 2022 update KB5019964, AES is the default for all AD accounts that did not have the administrator explicitly set a different encryption scheme. However, administrators may have done that on your domain in the past, because back in the day, the default encryption scheme was not even RC4, but DES, which is even worse. Some people therefore set everything to RC4 by hand, before AES was introduced as an option.

The allowed encryption types are set via the msDs-supportedEncryptionTypes attribute on each individual AD account. This property is a 32 bit bitmask, where 8 is AES128, 16 is AES256, and any other bits set are garbage encryption schemes. However, if the attribute is set to 0, the account reverts to the default, which ever since the aforementioned patch has been 24 (AES128|AES256).

Anyway, the following Powershell (run with elevated permissions on the domain!) lists you all insecure user accounts:

Get-ADUser -Filter 'msDs-supportedEncryptionTypes -ne 0 -and msDs-supportedEncryptionTypes -ne 8 -and msDs-supportedEncryptionTypes -ne 16 -and msDs-supportedEncryptionTypes -ne 24'

Remember that computer accounts have passwords too:

Get-ADComputer -Filter 'msDs-supportedEncryptionTypes -ne 0 -and msDs-supportedEncryptionTypes -ne 8 -and msDs-supportedEncryptionTypes -ne 16 -and msDs-supportedEncryptionTypes -ne 24'

You made a clear assertion about the need for cars, regardless of urban density.

But it turns out that actually urban density is pretty good indicator of reasonable public transport. of _course_ there are black spots, rural england lost its trains in the 60s and busses in the 2000s.

But

The british didn't make the tube for tourism, given that they've not built anything transport wise since the 90s (except the Elizabeth line)

Paris didn't make the metro for tourists, because they are french, they're not going to spend money on dirty tourists who get in the way.

the Netherlands didn't make trams for tourists, they can cycle like the rest of us.

I understand skepticism in the age of LLM-generated content and CAPTCHA-solving bots. What I don't understand is why people choose such weird hills to die on and think that posting about it will accomplish anything. Do you think people will read your comment and go "gee, I was going to use Kagi but now I won't because this random person has a bad feeling about a series of comments they remember seeing"?

I signed up for a specialist forum not too long ago and posted an honest review of a product because I hadn't been able to find one anywhere on the internet. Immediately a bunch of people accused me of being a "shill" for a direct-to-consumer business that's been powered by a Yahoo storefront for the last 20 years, as though a business that's run by a guy with an AOL e-mail address is sophisticated enough to figure out Fiverr and astroturf their reputation on a phpBB forum.

Think about it for just a moment - do you really think that the Hacker News audience is large enough or full of enough tastemakers to sway an alternative search engine's market share? It isn't. If Kagi wanted to do that they'd hire TikTok influencers.

The PostgreSQL license does not have a termination clause, you added that. I see that you are trying to use the PostgreSQL license as the basis and simply add the patent clause onto it, but it fundamentally changes the license.

I hope you can look at the Apache 2 patent grant as a better clause- or even adopt something like Google's Additional IP License found here- https://www.webmproject.org/license/additional/, which doesn't modify the open source license but instead adds an additional grant as a separate license.

Supabase is doing great work, thank you!

I do some personal R&D and want to keep it under wraps until I'm ready to share it to the world. Keeping stuff on services you can depend is great for many things (I use SourceHut, btw.), but sometimes you want to have your code on-premises.

This is not the next billion dollar business, but I don't want to share the code until I write a couple of papers on it, and anchor the code's and idea's provenance correctly.

I had a softer stance on the issue, but since AI companies started to say "What's ours is ours, and what's yours is ours", I need to build thicker walls and deeper moats.

No, it won't be permissively licensed if I open source this.

I had to double-check my source and I realize the error was mine. “40% read at or above an eighth grade level” is the correct description of the state-level data I was looking at, which is distinct from the general metric used for literacy.

This led me into a bit of a rabbit hole trying to understand what in fact the official literacy rate is measured by if it’s so wildly different from - indeed almost double — the portion who can read at an eighth grade level.

The data is actually quite interesting. US National Center for Education statistics administer tests to assess “the ability to understand, evaluate, use, and engage with written texts to participate in society” and an individual falls into one of five categories. Official literacy definition considers above category one (“below basic”), but it is category three that maps approximately onto “eighth grade knowledge” (thus four as high school, five as post-graduate). The most interesting thing I found in the data is exploring that gap between two and three, ie states that have a high attainment of official literacy but then very low rates of the higher levels. California, for example, has the highest percentage of people below level two, but a relatively high percentage at level three and above — obviously I haven’t considered the data for long enough to conclude, but that suggests to me largely a question of immigration/non-English speaking populations. The state I’m from does better than California on attainment of level two, but significantly worse at attainment of three or above.

States where level 3+ > levels 1-2: District of Columbia, Washington, Minnesota, Oregon, Massachusetts, North Dakota / Utah / Colorado.

States with lowest level 3 (ie “eighth grade” equivalent) attainment: Mississippi 35%, Louisiana 35%, West Virginia 37%, New Mexico 39%, Nevada 39%, Alabama 39%, Arkansas 39%, Texas 40%, Tennessee 40%, Kentucky 41%.

TLDR that gap looks like an interesting way to separate issues with a state’s educational system from other questions. Whatever the best measure of literacy may be, it seems like the bar should be a bit higher than just “native speaker of the measured language.”

I understand where it's coming from, but I have to disagree about the populist activism part. I don't think that pedestrians should worry about how to fit cars in their proposed solutions. That's something for the car proposers to do. It's not like the other way around is different. Just take a walk in any big city and you will see how pedestrians are a second thought in most of the roads.
