Hi everyone,

Today, I want to introduce you to my application, formpipedb.

In formpipedb, you can:

Manage Databases: Create new databases from scratch or import an entire database using an SQL script. You can oversee all your databases from a central dashboard, including exporting them to an SQL file for backup.

Create and Manage Tables Visually: Build tables without writing any code. You can define columns, select data types, and establish relationships between tables using a simple interface. You can also create tables by uploading a CSV file or pasting a CREATE TABLE SQL statement.

View and Edit Data Easily: Interact with your data in a spreadsheet-like grid. You can add, edit, and delete rows directly in your browser. The interface offers helpful inputs like dropdowns for linked columns.

Build SQL Queries Visually: Use the no-code query builder to select tables, join data, and filter to find the exact information you need. As you build your query, FormPipeDB displays the generated SQL code in real-time, which you can copy and use anywhere. You can also preview the results and download them as a CSV file.

So sign up today to start using formpipedb.

> If only it weren't for those few tweets, it would be successful and done by now.

Not what I said. I said he did it to try and kill high speed rail, not that he was solely responsible for its failure. And Musk did a whole lot more than tweet.

Just because you are ignorant of the significant evidence that this was (and remains) Musk's goal doesn't mean it isn't true. Ashlee Vance wrote about this way back in 2015: https://x.com/parismarx/status/1167410460125097990 . Just this year he used his involvement in DOGE to cut federal funding for what remains of the project: https://gizmodo.com/musks-doge-takes-aim-at-california-high-...

"How can you have such an uninformed take?" Personal attacks are against HN guidelines.

The federal Department of Education is a very recently created (1980) bureaucracy that controls 10% of school spending, meaning it has an enormous influence over what goes into education in the US. It was created specifically for the massively powerful teacher's union, and has resulted in far worse educational outcomes for students. Student's come last in public schools now.

The headline is about the landing, but the issue here happened at takeoff. There were 100 mph winds at the destination and this was their 4th fallback attempt and their third airport. This flight should never have taken off, the risk of multiple diversions was easily predictable, but the flight took off headed toward an airport in dangerous conditions, got diverted to a second airport that was just as dangerous, then finally to a third where conditions were so bad other flights were being cancelled (https://uk.news.yahoo.com/storm-amy-brings-flight-chaos-2019...) and where it finally landed because it was either land at that airport or land somewhere that is not at all an airport. Once this flight was in the air, disaster was more or less inevitable and we lucked into a narrow eviting window.

If you think of each button press as a matrix being added to the board state where only the row and column are set to 1, along with the commutative nature of the moves (order doesn't matter), then as long as the total number of "flips" from the cumulative matrices of moves is odd, then it will reset the board.

Mathematically I might say that the system's precomputed solution vector is readily apparent.

I’ve been saying this for years now: you can’t avoid communicating what you want a computer to do. The specific requirements have to be made somewhere.

Inferring intent from plain english prompts and context is a powerful way for computers to guess what you want from underspecified requirements, but the problem of defining what you want specifically always requires you to convey some irreducible amount of information. Whether it’s code, highly specific plain english, or detailed tests, if you care about correctness they all basically converge to the same thing and the same amount of work.

Most electronic power supplies for computers and similar devices (like e.g. modern TV) have zero complaints about being fed such DC.

Sadly only those that try to sell to Alirack applications (i.e., Chinese server PSU's like for example Lenovo Servers) bother testing in QA and doing enough design review to officially claim that support on their data plate.

You can tear down a sacrifice from a series of identical consumer PSUs though, and reverse engineer the front end schematic to check that the AC side of the active power factor correction design that you'd find in e.g. a decent gaming PSU doesn't do anything that would react badly to a lack of AC.

This is a great list of academic attacks, but it proves less than you think.

Yes, TEEs have been broken in dozens of ways. Side channels, transient execution, voltage manipulation, interrupt timing... etc. To be fair, you could make an equally impressive list for many security primitives.

The question isn't "can TEEs be broken?" since clearly they can, but rather what's your threat model and what are your alternatives?

What TEEs actually defend against is passive compromise. They force an attacker to actively exploit rather than just read memory. That legal and operational distinction matters enormously in practice.

The alternative to TEE is "no hardware isolation at all," and that's strictly worse for every threat model where TEEs provide value.

Additionally, you still get attestation which gives you cryptographic proof of what code is running.

>> "1g of cocaine might get 10-30 days" > Source please.

Google: how many days of jail time 1 gram cocaine california

As with many legal questions, the matter of jurisdiction comes into play. Possession of any amount in Texas, is supposed to dictate a higher length sentence on average. Florida, heavier than CA but far less than TX guidelines. In actuality, courts tend to sentence based on defendant history and current political climate.

Imagine you're standing on a balcony and discover that the supports are cracked almost all the way through.

Do you shrug and say, that's why they have a safety factor, everything worked as intended? Or do you say, holy crap, I nearly died, how did this happen?

The purpose of the safety factor is to save you if things go badly wrong. The fact that it did its job doesn't mean things didn't go badly wrong. If you don't address what happened then you no longer have a safety factor.

>If you insist on thumping your chest about your independence

Isn't that just basic conflict of interest disclosure? If he didn't say anything, that would be deceptive. As it is, I can make up my own mind and be aware of the link. Or should they just never write anything about Amazon? Your take seems to lack any nuance and present a false dichotomy. I can dislike the influence of large corporations over jocularism and also recognize that bias and influence do not mean 100% control over what every journalist writes.

Interesting! I feel I’ve been kinda foggy in my head since I quit smoking a year or two before covid and it then got worse with the pandemic. And I’ve felt there’s been more effect from a night out with party smoking than just seeing an old friend. Might need to try my own home grown snuff when it’s done and not just give it away.

This is really helpful and I think I understand now.

The approach is basically “accounting for everything that might go wrong to the best of our experience, including problems arising from the complex interactions between the airplane and supporting ground systems and processes, this is how much fuel you need in the worst case scenario. And now lets add more to give us a cushion, and we will treat consumption of this last reserve as tantamount to a crash.”

> thus have much longer glide range

Im gonna be a little pedantic, but the weight has surprisingly small effect on glide range, actually none of the weight affect the range directly, its all from secondary effects.

The glide is given mainly by drag and lift (so body and wing geometry), correlated to certain speed. The weight isnt in the equation at all. What weight does, is increases the speed in which the aircraft achieves this maximum glide ratio, and in higher speed you have higher drag, which finally reduces the range.

Thats why many modern gliders have water tanks in wings, to increase the weight of the glider, moving planes speed of best glide ratio higher, allowing for more efficiency at higher speeds. Its worth it if the atmospheric condition provide strong lifts. Pilot can then dump the water in flight to reduce the wing load, allowing them to land with less speed, or just keep in the air longer as thermals get weaker in the afternoon/evening

(source, I used to be a glider pilot)

Yeah, I'm extremely loyal to ChatGPT Plus and Codex, but is't because OpenAI has a native Mac app that I like, and Codex included with Plus and has served me well enough to not look at Claude. I like GPT-5 quite a bit as a user. I'll concede none of these are small things - they've had my money for 2+ years - but they're not gigantic advantages either.

At an enterprise level however, in the current workload I am dealing with, I can't get GPT-5 with high thinking to yield acceptable results; Gemini 2.5 Pro is crushing it in my tests.

Things are changing fast, and OpenAI seems to be the most dynamic player in terms of productization, but I'm still failing to see the moat.

Because immediate visual feedback is more natural than having to imagine an operation in your head, it's the same logic for multiple cursors - where it's even harder to understand what "change this word" will actually change.

> why THAT of all things?

Because that's a fundamental improvement

There were a few blogs with more detailed explanations, not sure about Helix, but kakoune had it covered https://kakoune.org/why-kakoune/why-kakoune.html

> Kakoune tries hard to fix one of the big problems with the vi model: its lack of interactivity. Because of the verb followed by object grammar, vi changes are made in the dark, we don’t see their effect until the whole editing sentence is finished

Stratechery has always been shallow, but these overt advertisements are disturbing:

- Sneaking in how someone went from a Sora skeptic to a purported creator within a week.

- Calling the result the "future of creation".

- Titling the advertisement "It’s OpenAI’s World, We’re Just Living in It".

What they are doing here is to pitch Sora to attention deficit teenagers in order to have yet another way to make the hair of the favorite content creator red. As if that didn't already exist.

The victory lap from Sam Altman and all the money being raised makes people forget the following:

- Open source LLM models at most 12 months behind ChatGPT/Gemini; - Gemini from Google is just as good, also much cheaper. For both Google and the users, as they make their own TPU; - Coding. OpenAI has nothing like Sonnet 4.5

They look like they invested billions to do research for competitors, which have already taken most of their lunch.

Now with the Sora 2 App, they are just burning more and more cash, so people watch those generated videos in Tiktok and Youtube.

I find it hilarious all the big talk. I hope I get proven wrong, but they seem to be getting wrecked by competitors.

This is unfortunately exactly why I never used (neo)vim or kakoune (or tbh, sublime text whose lsp integration I have never successfully gotten working). Going from school (Java + NetBeans/C# + Visual Studio) to work (C#/JS + Visual Studio -> C#/TS Visual Studio Code) I had expectations for certain language features being available by default. Helix is the first editor of its ilk to get configuration out of my way so I can effectively write code the way I'm used to.

We already have robots that work in shared human spaces, and our experience in that domain has shown that you need to put a lot of thought into how to do this safely and specifically how to prevent the robot from accidentally harming the humans. Ask anyone with a robotic cnc machine how they would feel about running the machine without its protective housing for example. I expect they will start to throw up just a little bit. Flexibility is exactly the opposite of what you need until we have a CV and controller combination that can really master its environment. I could forsee a lot of terrible accidents if you brought a humanoid robot into a domestic environment without a lot of care and preparation for example.

The footage is analog (on film). It was shot with 0 pixels, so 4k pixels on an edge doesn't matter. Side note, footage itself is a term derived from film (how many feet of film).

You can scan film into whatever digital resolution you want. You could do an 8k scan if you felt like it. You might run into issues where the resolving power of the film is less than the scan, but 4k is not an unreasonable resolution to pull out of well lit studio shot movie stock.

What's really going wrong: [1]

It's not the boring process. It's the use of concrete curing accelerants producing toxic sludge.

Often, the accelerants would spill into groundwater and mix with concrete and other debris, creating a toxic mix of sludge, sometimes about two-feet deep, that workers would often have to trudge through. The OSHA report cited workers with permanently scarred arms and legs, and one instance in which a worker was hit in the face and seared with the chemical mix. Temperatures would regularly rise to 100 degrees as workers often toiled for 12 hour days, sometimes for six or seven days a week, at a worksite nicknamed “the plantation” by some workers, who spoke to the Nevada safety agency for its report. Workers also claimed having to ask for permission to use the bathroom.

That's the OSHA complaint. The environmental complaint comes from disposing of that sludge.

Sludge removal and treatment is a standard problem in tunneling. Usually, it's pumped out with "trash pumps" that can tolerate rocks and sand. Then it goes through some basic processing - screen out the big rocks, separate water from wet sludge, run the water through a mini sewerage treatment plant on site, squeeze more water out of the sludge, add bentonite as an absorbent to lock up toxics, and truck away the dry sludge.[2]

What it seems The Boring Company has been doing is dumping the wet sludge on a vacant lot in Las Vegas [3] and waiting for the water to run off or evaporate. The vacant lot isn't even out in the desert outside the city; it's in town, and the nearby mall is annoyed.

Reports of water two feet deep in the tunnels means they skimped on pumps and water processing. They're using a TBM, which makes a concrete tube as it digs. Most tunneling operations keep the completed tube dry.

I worked on a python codebase for several years that had over two million LoC. The code was well-organized and under constant development by at least ten devs. There were Java components in the larger project that were occasionally touched on, and it was always slower to work with those parts.

A well organized python codebase really is faster to work on than other languages. If your dev work is slowing down as the codebase grows, that's a sign you're accruing tech debt by not keeping up with organizing it.

> The minutia is sticky with these sort of almost-but-not 'universal' interfaces.

True, but that's not really applicable here since LLMs themselves are not stable, and are certainly not stable within a vendors own product line. Like imagine if every time Oracle shipped a new version it was significantly behaviorally inconsistent with the previous one. Upgrading within a vendor and switching vendors ends up being the same task. So you quickly solidify on either

1) never upgrading, although with these being cloud services that's not necessarily feasible, and since LLMs are far from a local maxima in quality that'd quickly leave your stack obsolete

or

2) being forced to be robust, which makes it easy to migrate to other vendors

When we were in Vegas for Def Con, one of the tube stations was next to one of the Las Vegas Convention Center entrances. I'd occasionally hang out there with friends, and once every half an hour or so, we'd see a lonely Tesla weave through the traffic cone path and disappear into the nethers.

Based purely on my own observations, I'd guesstimate that station sees about 50-75 cars per day.
by Aeolun | 2025-10-10 18:38:35+00:00
I don’t think that’s so much? A car burns 1 liter to travel 15 kilometer’ish, and carries 4 people.

An airplane burns 40 liters to travel 15 kilometers too (900 kph), but carries 160 people.

That’s about 40x more than the car, so the fuel economy per passenger is about the same.

Of course jet fuel is probably a bit more polluting, but it’s still interesting how close it is.

its not THAT exceptional. I myself know several people who bootstrapped themselves into being descent software engineers. Traditional education is certainly fine for some people but its not the only way for the masses to learn. whats missing is the discipline of pushing yourself when you have no immediate extrinsic motivation.

You might have had a point a few decades ago when the information itself was difficult to fine but with the internet and online courses, its easier than ever to teach yourself in a "nontraditional" setting.

This seems like a reasonable response by MIT. I’m struggling to understand where the core disagreement lies though. Would someone who is opposed to this “compact” care to explain their view? I’m not interested in baseless name-calling (“fascist” etc) but I am interested in cogent reasoning.

I didn’t read the compact itself, but I did read the wikipedia article about it, and it seems to be a very positive set of criteria (safeguarding individuality and merit, protecting against the formation of ideological monoculture, protecting against hostile nation-state actors, etc)

It’s bizarre actually, because these institutions should be doing all of these things already. I don’t know what to make of the fact that they aren’t.

This game is old as the world, "Christian" is different things to different people. How many would call Trump "Christian"?

The point being, one man's Christian is another man's anti-Christian, that is, anyone can be either depending on the whim of the Watcher and if the Watcher isn't watched, anyone can be a domestic terrorist, suddenly or gradually.

I think history would agree eventually that his timing was unfortunate. The changes in technology (social media, smartphones,etc..) and the 2008 financial crisis culminated in large scale social changes and dissatisfaction. That along with aging politicians stuck in their old ways was a huge challenge. And he could have maybe overcome all that except for the fact that even in Obama's own lifetime, half the country didn't want black people to have the same rights as whites, so he had to deal with the racism.

It all comes down to money and the gravity center of finance. Those who wanted in on commerce and rising wealth used racial attacks against him to inflame a discontent society, and the figurehead of that inflammation seized power. As they say, "America sneezes and the rest of the world catches cold", it would have been britain, ottomans,hispania, portugal, baghdad,ctesiphon, karakorum,venice,rome,etc.. in different times of history. but it is the US now, and as a result the world caught the fascism fever. I think that means Obama inadvertently was instrumental in the collapse of US-centric world older and in the shifting of center of gravity once again. I don't see beijing picking up the slack, it would be less chaotic if it were that simple. but i'm concerned the US itself won't make it till the end of this decade and I don't know what will come afterwards.

China has been in times past set to take on the throne but they've been complacent and isolationist. That I think means a contraction of US's reach and influence with an unfilled vacuum, starting in Europe and spanning the globe. It might be decades before there is any kind of stability. It's basically wealthy people of the west not wanting to accept reality that's keeping things afloat so far.

If McCain won in '08 and Obama won in '12, the swing may have been wildly different. If Romney won '12 there wouldn't be a trump admin. You'll notice that a lot of people agree that things started going really bad around 2013-15, that's on Obama's second term, after the snowden leaks. Brexit and other far right movements also peaked then. He isn't responsible and he didn't mean to, but the current state of things wouldn't have occurred without him.

One thing he could have helped though. He could have avoided making fun of an insecure billionaire at the white house correspondent's dinner. and that certain billionaire (with a long documented history of discriminating against blacks and working for the russians), wouldn't have made it his mission in life to dismantle reverting that represented Obama.

> there appeared to be one vehicle in service on the entire system

I watched that video the other day, pretty sure it didn’t say that. What it did point out though is that in most of the system, other than the one main line, there’s just one single-lane tunnel so that when a car is in a tunnel going one way, cars going the other direction have to wait to enter the tunnel until the tunnel is clear.

The title of the video seems pretty accurate: “The Vegas Loop Is Getting Progressively More Stupid.”
