I used TiddlyWiki a lot to manage my D&D 3.5 campaign back in the day. As I recall, it originally was a true stand-alone HTML document capable of overwriting itself, but once browsers dropped support for this capability, users had to begin using various workarounds, and this remains the status quo today.

TiddlySaver.jar was one such workaround. A check in the Wayback Machine suggests that it was originally required only for Safari, Opera, and Chrome; IE and Firefox needed no such plugin. Nowadays, there are several workarounds, and setting up one is a mandatory installation step: standalone applications, browser extensions, servers, etc. Some are clunky (e.g. you have to keep your wiki in your Downloads directory or the browser can't write to it), and either way, TiddlyWiki is no longer truly a single stand-alone HTML file, at least not for writing purposes. It's still a very versatile tool, though.

> tossing a doc about company benefits into a bot is about the most worthless thing you could do with this tech.

Hahaha, my company has spent half a year pursuing the exact same thing to the letter after one of our VPs got the idea in his head at some AI conference. Rollout kept getting pushed back because of hallucinations in testing. I'm not 100% sure at this point if he forgot he made it a top internal priority and it was quietly shelved or if it's still limping along with no one in HR/upper management willing to give it the green light for release.

(using throwaway because my HN profile is linked to my real identity).

Very interesting model. Some key points from the blog:

* NVIDIA is also releasing most of the data they used to create it, including the pretraining corpus

* The model uses a hybrid architecture consisting primarily of Mamba-2 and MLP layers combined with just four Attention layers. For the architecture, please refer to the Nemotron-H tech report. The model was trained using Megatron-LM and NeMo-RL.

At this size and with only 4 attention layers, it should run very fast locally on cheap 12GB GPUs.

It is in Applied Optimal Control by Bryson and Ho (1969). Yann LeCun acknowledges this in his 1989 paper on backpropagation:https://new.math.uiuc.edu/MathMLseminar/seminarPapers/LeCunB....

> "Since his first work on the subject, the author has found that A. Bryson and Y.-C. Ho [Bryson and Ho, 1969] described the backpropagation algorithm using Lagrange formalism. Although their description was, of course, within the framework of optimal control rather than machine learning, the resulting procedure is identical to backpropagation."

You really need to be in the middle of nowhere for a 200 mile range to be a problem. I've made quite a few trips in my Bolt where I worried there wouldn't be coverage (rural Indiana was my biggest concern), but it consistently turned out to be unfounded. In rural areas chargers certainly thin out, but you can safely drive the interstates and the vast majority of state highway with less than 100 miles between chargers.

Thanks. I understand the motivation for them being there. I think I'm just too old for it or something.

The danger is the fun. Ive noticed many games these days disable alt+f4. I consider it the same weird guardrail. The enjoyment is tricking people into doing things, or having a laugh after having been tricked. It's one really good way to make folks learn.

But also it can be bad. I get it. I'm just old.
Show HN: WhatIfInvest – explore "what if I invested" scenarios
by klinkworks | 2025-08-18 23:37:35+00:00
Hey HN! I built WhatIfInvest to make it easy to answer investing “what if” questions in an approachable way for both new and seasoned investors.

With it you can simulate historical returns for stocks, ETFs, or crypto, backtest custom-weighted portfolios, visualize dollar-cost averaging strategies, and share results instantly with simple links

Some examples you can try include seeing how Nvidia vs. Bitcoin performed over the last 10 years, how a classic 60/40 portfolio held up, or what dollar-cost averaging $100/month into SPY since 2010 would look like.

I realize these comparisons can spark a bit of FOMO, but the intent is to highlight the power of consistent investing and (hopefully) encourage more people to get started.

Would love to hear your thoughts, feedback, or ideas for what to add next.

I don't think they do that good a job of explaining what it is, but the Reddit post linked below included this comment which is helptful: "You know how when you search your notes for something, say a phrase? Well, Bases can basically hold a static search that automatically updates. And, instead of searching all over again, you just click into the Bases file and new notes are just there in the default table format.

On top of that, you can add other properties to the view, especially one like modified date, which updates every time you modify the file. This is useful for seeing which files you haven't looked at in a while. Old concepts often apply to new ones, but we sometimes forget to check back to make that connection explicit."

I doubt RMS frequently borrows phones from strangers. It's usually from people who know him and are with him. They already have the phone, so RMS's using it doesn't increase the tracking it's already doing, and in some ways it pollutes the tracking data, also good.

I once suggested some alternatives to him like Meshtastic, but he travels too much to random places for that to be practical.

Isn't it China that adopting renewable more rapidly than anywhere else and also has a booming economy? Although they're also investing in non-renewable energy sources.

My understanding is that "green" investment portfolios which were intended as "ethics over return on investment" have actually outperformed petrochemical stocks for years now, and it's more ideology than economics that's preventing further investment (hence why you see so much renewable energy in Texas which is famously money driven)

> Summaries are subjective

Yes, so what? The comments on a submission are subjective too.

I still don't know who you think the "bad actors", "charlatans", and "sophists" are, how they can "invisibly rewrite history", or what you think "gamed" means, aside from getting people to click the submitted link.

The entire point of my proposal is simply that a summary of the article, longer than the article title but still relatively brief, can frequently be a better guide than the article title alone as to whether the article is worth reading. That's it. So the histrionics about rewriting history and such just seem bizarre and inexplicable to me.

> the objective nature of the original content

Objective in what way? The submitted article may itself be an opinion piece, and often is.

Anyway, nobody would be stopping you from reading the article. Quite the opposite: the point of the summary is to explain why you should read the article yourself!

Here's an example: https://news.ycombinator.com/item?id=44945966 The article title is "What could have been". The article title is so extremely vague as to be useless. I have no clue what it's supposed to be about.

digression: I use Google Fi as my carrier but it's an MVNOs that's largely on T-Mobile. I don't believe Google Fi is selling my location data (they already know it via other ways), but since it runs on the T-Mobile network, they might still be able to? But since I lack a T-Mobile account there's no way to opt out.

Anyway know the story on location selling + Google Fi? Or with MVNOs in general.

"sanctity of the voting booth"?!

> More than one in five polling places have closed over the last decade, according to an ABC News and ABC Owned Stations analysis of data from the Election Administration and Voting Survey, the Center for New Data and the Center for Public Integrity. https://abcnews.go.com/US/protecting-vote-1-5-election-day-p...

This is after Shelby County v. Holder, and now states are shutting down polling stations to suppress the vote --- well you can no longer accuse them that in the courts, but it is clearly what they are doing.

Just like how Alabama passed a voter id law and then closed half their DMVs, the ones in black neighborhoods. https://slate.com/news-and-politics/2015/10/alabama-closes-d...

There's no "sanctity of the voting booth" - shutting down polling stations and DMVs and then requiring people to visit the DMV and the polling station and making it intentionally more difficult for some people, this is all very very obvious and you can't hide it from me by waving a flag in front of my face.

Here's the actual plan:

Require in person voting, "protect" the polling places with armed masked goons working for ICE to "keep illegals from voting" and then call it freedom.

Give me a break. Do you really think we're that dumb?

Please note, the context here is level 1 charging. 7.2KW is level 2.

With level 1 charging is only 3 to 7 miles per hour, so average of 35 miles in a 7 hour day (assuming you drive for your lunch break). Where I am, the average distance to work is around 27 miles (one way), so a net loss of charge.

It has been a problem! Even paper ballots have been a problem!

Jimmy Carter has documented his own first hand account with it.

> We asked John Pope, a friend of ours, to go to the courthouse to represent me. When he arrived he was dismayed to see the local political boss, Joe Hurst, ostentatiously helping my opponent. He was requiring all voters to mark their ballots on a table in front of him and telling them to vote for Homer Moore. The ballots were then dropped through a large hole in a pasteboard box, and John watched Hurst reach into the box several times, remove some ballots, and discard them.

disagree, I think paper ballots are just as easily hacked(printers are cheap). I think that while technical mechanisms are nice and should be used, they should not be depended on to secure the election. The only real solution is to have a politically neutral well motivated uncorrupted election officer corps. and if this sounds hard, it is. Thus why people keep trying to turn to technical means to secure an election and are baffled when it lets them down.

Among it's many faults, I think this is one advantage of the weird US method of running elections at the county level. While it is probably easier to corrupt individual election corps, due to it's distributed nature it is harder to systematically corrupt all of them. This does mean that US elections are strangly inconsistent from county to county, but that is the price you pay for a distributed system.

As a counterpoint to the "electronic election transactions are impossible to secure" platform, look at the credit card processing systems, yes there is fraud, but compared to the volume of daily transactions it is insignificant. the point being, large scale trusted electronic transactions are possible.

Remember, this is basically your own personal Wiki. You can either embrace and accept a rigid organizational structure or not. You are signing up for a lot of up front maintenance and design this way. The alternative is to heavily use links, tags, and other tools that make it easy to find data later.

For a personal knowledge base I think the latter approach saves time in the long run. I have clusters of well organized information. Well tagged and linked. I can always find my movie ideas, projects, and deep thoughts when I want them. I like the idea of just curating the clusters I care about. Just enough organizing. I then have a few highly connected entry points to my clusters. Often I find people don’t link enough in their Obsidian. It’s free and puts things in a more graph oriented layout that the tool can show you.

Edit: oh, also remember, these are text files. Grep still works. Also, we have very powerful CLI LLMs to summarize and categorize text data rapidly. Like “suggest 3 tags for this document based on <prompt magic here>. :)

The actual argument by anyone who cares about voting rights concerns structural barriers to obtaining ID (hint: doesn't include stupidity). India's Aadhaar ID system, which still struggles with duplicate and missing voter records, doesn't magically solve any of the problems you mention.

> Not "let's have just anyone vote and we'll trust their word".

That's not how it works here. Voter registration requires proof of eligibility, poll books, signatures, and address checks are used for verification. Thanks in part to multiple levels of safeguards, impersonation fraud has been effectively non-existent. Of course, Rockland County and similar cases may prove the existence of other attacks on our democracy that don't depend on impersonation fraud.

> that segment is small and rapidly becoming non-existent

Disagree. People vastly overestimate the complexity of hybrids.

The mechanical and electrical components in a Toyota-style planetary gear based hybrid are much simpler than a standard automatic transmission, and demonstrably more reliable than both a conventional automatic and belt-style CVT.

This is a long way of saying, the specific market segment hybrids are a good fit for is the set of all passenger car customers that an EV is _not_ a good fit for. Anyone buying a Corolla, Civic Rav4 or CR-V should be buying the hybrid, and sales seem to be trending that way.

Reels and Shorts derive their power from the fact that we pay higher attention to motion than to colors or shape. Blinking colors attract attention for the same reason. This observation makes it easy to neuter them: reduce framerate from 120 fps to 1 fps unless a touch is detected. This way scrolling will keep working as usual and videos can be watched if you keep pressing the screen, but the unwanted guests that abuse our attention will be left in the dust with 1 fps. Great for battery life too.

> but hybrids are still obviously better

Like a lot of anti-EV commentary^, there's nuance being missed and that is: use case. There is no "X is obviously better" (this is also true for a lot more topics than this)

I have a Nissan Leaf that's perfect for the purposes we bought it, better than a hybrid, far better than a petrol or diesel car. There are also scenarios where a hybrid is better, and there are also scenarios where a great big diesel burning engine is the best option. These gaps are closing though.

^I've had frustrating conversations with relatives when discussing the possibility of buying an EV where they just round-trip through a list of negatives, and I have to explain repeatedly that they don't apply to our use case. Examples:

- Can't tow: I haven't towed anything with any of our ICE cars in years (and we still have the ICE cars anyway)

- Can't take it interstate: We're not planning to take it interstate, and we're not planning on buying one big enough to carry what we'd need for an interstate trip anyway.

- Wouldn't a hybrid be better / safer first option to dip into electric: Not for our very regular and frequent short trips, pure electric is simpler and cheaper, and I've done the research to be confident in the decision.

- Miscellaneous other: We're not actually getting rid of the existing cars (yet) so we're not losing anything you might be worried about us losing.

The Leaf is on track to have saved us nearly $2k in petrol for the year (even taking into account the cost of electricity to charge her). If she lasts another four years she'll have paid for herself.

If the OECD is to be believed, the elephant in the room is that China negated the value of western R&D by about $500B per year since 2010.

That’s why being a fast follower is so valuable, you get everyone else to waste money on the wrong ways to build things. It also causes R&D to show much worse returns.

We’ve worked hard to ensure that cultivated salmon cells are the first ingredient in our salmon saku (after water). After we harvest our cells, we integrate them with plant components to create the desired texture and flavor of a traditional salmon fillet.

In addition to water and cell-cultivated salmon, our saku contains fats derived from canola, sunflower seeds, and algae, soy (an allergen), potato starch, konjac (a root vegetable), beta-carotene and lycopene (natural colors), carrageenan (an extract from red seaweed), and natural flavors.

Hmm. They also compare their place to a microbrewery but I can't find any photos of the actual production process, generally a point of pride for a microbrewery. It sounds less like "lab grown meat" than literally "lab grown cells" + other stuff to mimic aspects of meat texture/flavor/color.

Yeah, Parakeet runs great locally on my M1 laptop (through MacWhisper). Transcription speed of recordings feel at least 10x faster than Whisper, and the accuracy is better as well. Push to talk for dictation is pretty seamless since the model is so fast. I've observed no downside to Parakeet if you're speaking English.

Aside from secondmind [1] I don't know of any companies (only because I haven't looked)... But if I had to look for places with strong research culture on GPs (I don't know if you're) I would find relevant papers on arxiv and Google scholar, and see if any of them come from industry labs. If I had to take a guess on Bayesian tools at work, maybe the industries to look at would be advertising and healthcare.I would also look out for places that hire econometricists.

Also thank you for the book recommendation!

India's voter ID cards are federal IDs issued by the Election Commission of India. There is no such widespread federal ID in the United States and likely no feasible candidates for quickly ramping up ID card issuance to all U.S. voters. And my guess is that most political support for voter ID laws is paired with explicit opposition to any competently-run federal ID program.

>There isn’t a single day where I don’t have to deal with software that’s broken but no one cares to fix

Since when does this have anything to do with AI? Commercial/enterprise software has always been this way. If it's not going to cost the company in some measurable way issues can get ignored for years. This kind of stuff was occurring before the internet exists. It boomed with the massive growth of personal computers. It continues to today.

GenAI has almost nothing to do with it.

iirc this bug existed from release but didn't impact the game until years later after a sizable number of DLCs were added to the online mode, since the function only got slower with each one added. Not that it's fine that the bug stayed in that long, but you can see how it would be missed given that when they had actual programmers running profilers at development time it wouldn't have raised any red flags after completing in ten seconds or whatever.

I feel like this vision of the world is completely antithetical to how humans work. I assert that humans don't want a UI that adapts to their use case, that they want an UI that is predictable and works the same every time, and it is funny to me, like how many companies realize they need to get rid of their cli/dsl in order to grow.

What? The requirements for this are nothing like what is required for sterilization of a Mars rover. NASA's goal is to not have a single iota of foreign organic material on rovers, which is obviously not even close to what is required here. The only thing you need to worry about with this stuff is whether there are any dangerous bacterium in it (e.g. salmonella), which can be readily monitored and avoided without herculean effort. And unlike real salmon, parasites and viruses won't have much opportunity to gain a foothold.

I do agree that youtube has made it much easier to self-promote, and that today's model has replaced the old one and is doing decently. Still, the at least by the numbers, the music industry is still smaller than it used to be. Unfortunately, money is a powerful resource, and it's not like the music industry took everything and completely screwed over the musicians. They helped struggling musicians survive, giving them a chance to make it, while taking care of a lot of the non-music-related tasks that are actually very time consuming - promotion, lining up performances, lining up interviews, learning the successful strategies for giving a band a chance to succeed, networking... It is really another job in itself and is very difficult.

Labels still do this today, but it's just the number of opportunities for musicians is smaller.

Although, again, do agree that youtube (and somewhat spotify from what I've heard) has made a huge difference. I've heard a few times that Youtube is probably one of the best resources for self promoting music, but being good at making videos on youtube is not easy to do well and is also another job in itself.

> - easy storage management, the "rampant layer violation" of zfs we really need;

Except in zfs you have to think if you really want that device in that pool or that vdev. I use btrfs, slow and kinda unsafe, specifically because you just specify raid1c2/raid1c3/raid1c4 and it kind of survives c-1 dead disks (until you run out of disk space and everything goes to flames).

> - integration of such storage to the software stack, from the OS to single packages, it's a nonsense having to "spread" archives in a taxonomy to deploy them or downloading archives to be unpacked as well for updates when we have send-able filesystems (zfs send of snapthots) and binary diff (from a snapshot "tagged version" of a fs-package to another, sent over internet).

We (kinda, for some very generous definitions of) have that in composefs? But I still sense even with that, you still want some resemblance of sanity in your indivual layers.

Weird ad hominem flex. And "across" doesn't imply multiple accounts at once. People who register with their company email may be forced to create a new account when they leave the company (perhaps with sudden and unexpected loss of access to the account).

Here's the actual guideline (not rule):

"Throwaway accounts are ok for sensitive information, but please don't create accounts routinely. HN is a community—users should have an identity that others can relate to."

People have commented both appreciating your clear definitions and calling you out for the condescension, with a perfect xkcd suggesting an attitude change. It's up to you how you react to such feedback.
