> How do you deorbit Venus is such a way that your inflatable balloon city comes to a gentle stop, 30 miles up, and just floats there?

Aerobraking with the balloon? A balloon the size of a city would slow down very fast in a thick atmosphere like that, then slowly descend until it reaches the stable altitude.

> Worse still, when people need to leave and return to Earth, how do you launch a rocket from the balloon city and return to orbit?

Spaceplane? Take off like a glider on a slope runway, then ignite the rocket.

> If there aren't materials to effect a repair, how long until it sinks down into the hellzone? Where are materials manufactured for repairs, and how quickly could they be manufactured and sent there?

That's a true problem. Local manufacturing would be on the surface. An elevator or cable car could make the connection to the ground facilities, if the winds aren't too strong. But the manufacturing of the materials would be extremely difficult in surface conditions.

> If a rocket is trying to land and goes off course, does it squash the balloon city like a grape?

Nope. See first answer.

> Saying that holes can be patched is well and good, but there are some truly catastrophic failure modes that don't seem entirely unlikely.

Possibly.

But the biggest question is why go there?

No, Watt-second-hour = 3.6 kJ, so J to Wh is moving the decimal place couple steps AND dividing by 3.6. The actual units used in circuit designs is mAh, so the decimal has to be moved for another time then divided by 3.7[V] again. That's too much for a smooth-brained man like I am.
AI video generation is a threat to freelance editors
by jamessmithe | 2025-09-22 11:15:09+00:00
Ai generated videos are changing the whole dimension of video creation these days. Recently, I needed some video for projects and I was searching for some tools that can get the job done for me. When I found the tool, my mind was just bloen away with the videos I got from there. The quality and clarity of the videos was simply awesome. I mostly used synthesia, invideo and lunabloomai. When i saw the result, I had this question in my mind. What is the future of the freelance editors since these tools are giving such awesome results? What do you guys think?

I agree that the tone of arguments of many proponents is not helpful. That obscures the fact there are relatively easy things that can be copied from the Netherlands to make a city more walkable that are not expensive. Chiefly: start making a division between "streets" and "roads", where one is just for destination traffic with shops and houses, and the other is a through way to get from one neighborhood to another with as few traffic lights as possible.

People love to get rid of traffic along their house so it's easy to get buy-in from the public to convert their area to a neighborhood without through traffic, even when that means they have to navigate a few blocks to get in and out of their neighborhood. This results in more traffic pressure in the surrounding area, but that's not as bad as you think because you can remove a lot of traffic lights if there are fewer roads in and out of a neighborhood. Slowly build up to more and more of these areas.

If the only cars in a neighborhood street are from people who live there then traffic intensity is low enough that no bike lanes are needed there and kids can play in the street. Finally, if all that works, you can start stringing neighborhoods together with dedicated bike lanes, away from streets with cars. Bike lanes that are not part of a road are surprisingly cheap because road wear scales with the third power of vehicle weight so those rarely need resurfacing.

This is often overlooked, to the point I created a website focusing on "the code we actually put into our computers":

https://whatsrc.org/

It doesn't index all of npm, only if the package was reference by a Linux distribution somehow (e.g. package-lock.json in a tar file used in an Arch Linux PKGBUILD).

I'm starting to wonder if there's a real difference between the populations who use em dashes and those who think it's a sign of AI. The former are the ones who write useful stuff online, which the AIs were trained on, and the latter are the consumers who probably never paid attention to typography and only started commenting on dashes after they became a meme on LinkedIn.

I bought a cheap(£150 at the time) phone 3-4 years ago called "Ulefone" where in a sense the 'case' is built in to the phone. It is marketed as a phone for handymen or outdoor functions.

It is a bit bigger with protective shell around it is bulky, but withstood all the drops that a typical phone would break. There is some flaring around the screen and camera that it prevents most of scratches. The back has some sort of hard rubber but it held up well.

I've only had to replace the screen protector within 3 years as the scuffs and marks made it difficult to see in well-lit environment.

I wouldn’t rate those as very serious issues for this project. They’ll only be triggered if there are over MAX_INT lines or depth levels in the input. Yes, an attacker might be able to do that, but you’d have to put that input in a memory buffer to call this code. On many smaller systems, that will OOM.

Skimming the code, they also are loose in parsing incorrect json, it seems:

static bool sj__is_number_cont(char c) { return (c >= '0' && c <= '9') || c == 'e' || c == 'E' || c == '.' || c == '-' || c == '+'; } case '-': case '0': case '1': case '2': case '3': case '4': case '5': case '6': case '7': case '8': case '9': res.type = SJ_NUMBER; while (r->cur != r->end && sj__is_number_cont(*r->cur)) { r->cur++; } break;

that seems to imply it treats “00.-E.e-8..7-E7E12” as a valid json number.

case '}': case ']': res.type = SJ_END; if (--r->depth < 0) { r->error = (*r->cur == '}') ? "stray '}'" : "stray ']'"; goto top; } r->cur++; break;

I think that means the code finds [1,2} a valid array and {"foo": 42] a valid struct (maybe, it even is happy with [1,2,"foo":42})

Those, to me, seem a more likely attack vector. The example code, for example, calls atoi on something parsed by the first piece of code.

⇒ I only would use this for parsing json config files.

Being tiny is one thing, but the json grammar isn’t that complex. They could easily do a better job at this without adding zillions of lines of code.

I was looking through my work email (my personal email is already too far gone) and realized 90pct of the messages were computer generated. Maybe not AI, but still all automatic process fired messages. I was looking for emails that were deliberately drafted by a human, not even sent only to me. Just messages that a human intentionaly made in the moment. Can't filter them out.

The terrifying reality is that there is no one to delegate to.

If we would magically spawn the theoretically ideal candidate who plans to do everything exactly the way you want it done then there is zero chance you will vote for them.

This goes for all voters. Exactly 100% of them without rounding anything.

https://www.fec.gov/data/candidates/president/?election_year...

You can't argue you don't need to know any of them because they aren't popular enough.

Democracy badly needs a better formula for discovery or some other means to add signal to the noise like a license to drive the country or some financial reward to get a diploma.

Maybe we could train an LLM to interview the voter.

If they can be private indefinitely, then you wouldn't need to keep them secret.

These attacks on freedom will continue until every computing device is mandated to have an ML system tracking your every input. And no communication method is safe from that.

Not even steganography would save you because more and more people would do it and they'd make it illegal too.

EDIT: Technology can give us tools to fight it but this has to be defeated at the political level, likely by enshrining privacy is a core human right.

- Going one after another for EU presidency since 2022 these countries were in favor: Sweden, Spain, Belgium, Hungary. Poland didn't want to include encrypted communication. Denmark wanted to include everything (text, links, videos, images, calls) but dropped text and calls after criticism (for now).

- Germany is currently not opposed to it (https://news.ycombinator.com/item?id=45273854).

- EU doesn't require all countries to support it on the council level (or parliament level). You just need at least 55% countries (at least 15) that represent at least 65% of citizens. To block it you need at least 4 countries that represent at least 35% of citizens, we are at ≈22%.

My ex was on antidepressants which had a huge impact on her life. If she missed her meds or (god forbid) was late on her prescription, it was terrifyingly bad.

Orthogonally, she also had sensitivities to light and epileptic symptoms. She told the doctor this, and the doctor doubled her dose of antidepressants. Just one of many, many stories. I've come to consider the higher-level of medicine quite scientific, but the on-the-ground doctors as unscientific. They mostly don't have time or enough feedback to make good decisions in most cases I've seen. That's a profession that shouldn't work on faith.

Yes, but any phone number will work. That’s irrelevant to the crypto part.

EDIT: (I’m throttled and can’t reply to the child reply) - I said ANY phone number will work. You can get a number from any country, or a VoIP number, or a landline. It doesn’t need to be a sim card from the country you’re in. It doesn’t need to be a sim card at all. Any number will work.

If your country requires details to get a number, get a number from a different country. Unless you’re in China or Russia, we’re on the same internet with the same access to jmp.chat and others.

i know this is amazing concept but you can just.. not follow the law, and use 'illegal' encrypted communication.

Steganography to do key exchange on any compromised channel using DH, and then you just send normal encrypted messages - their magical idea is to do client side scanning.

this does require control over your device, but such regulations would just spring up black market for such devices.

Could he have done more? Sure. But he spent a lot of political capital getting the ACA done. Then he followed traditional political decorum when the GOP pushed him around that in hindsight was a mistake. If all the rules both written and unwritten are going to be thrown out, the obviously it's best for the person who throws them out.

I haven't done any deep dives into their road data but there was ~80 GB of it, mostly from TomTom, in the August release. I think the big question would be how much overlap there is with HERE and how would the metadata compare.

TomTom did a few write ups on their contribution, this one is from 2023: https://www.tomtom.com/newsroom/behind-the-map/how-tomtom-ma...

If you have QGIS running, I did a walkthrough using the GeoParquet Downloader Plugin with the 2.75B Building dataset TUM released a few weeks ago. It can take any bounding box you have your workspace centred on and download the latest transport layers for Overture. No need for a custom URL as its one of the default data sources the plugin ships with. https://tech.marksblogg.com/building-footprints-gba.html

The government is emergent behavior of evolutionary pressures.

For most of human history, war of aggression was a matter of a cost-benefit analysis which often have more benefit than cost. That has changed (relatively) recently because of how destructive it is that even the winner does not gain from it.

Point being, hierarchical authoritarian structures are very good at war (and other kinds of competition). That's why they exist. But they should no longer be needed.

They are entrenched and we need to evolve away from them.

Slate Star Codex' take on Adderall (and ADHD) is a good read: https://slatestarcodex.com/2017/12/28/adderall-risks-much-mo...

In short: no-one "has" ADHD. We just decided that people on the lower end of the spectrum in the "ability to concentrate" trait deserve a bit of a boost from otherwise illegal drugs to function in the society. Being in this lower end is called "having ADHD".

DHH has great instincts when it comes to programming and technical projects, but he is not a very smart guy about anything else. Further, he is a bit of a low class buffoon. So just use his stuff and ignore whatever else he rants about on his own time and property, this is the only way to get by in life. You couldn't read a book, watch a movie, or enjoy any music, if you constantly had to vet the authors against your own political views.

Start charging users to submit a vulnerability report.

It doesn't matter if it made by AI or a human, spammers operate by cheaply overproducing and externalizing their work onto you to validate their shit. And it works because sometimes they do deliver value by virtue of large numbers. But they are a net negative for society. Their model stops working if they have to pay for the time they wasted.

As a non-white British person i have no problem with native meaning certain ethnicities - after all, no one would call a white American a native American.

What is very, very troubling is his idea that London of all places should be an ethnically white city. London has been multi-ethnic since the 70s or 80s, if not earlier. It is very much a world city.

The other thing is that he is Danish and seems to be projecting his feelings about Denmark onto Britain. He does not really understand how British people feel. The organiser of the march he praises is such as toxic figure for his blatant bigotry that the Reform Party (the most right wing party that has seats in Parliament) turned down a $100m donation from Elon Musk rather than allow him to join the party. e ethnic makeup does not bother any white Londoners I know (I grew up in London, so I do know a lot of people there). In fact, the only person I can recall complaining about it in real life was also foreign European.

The march was not actually that big. There have been many larger protests in London. From protests against the Iraq war (about five times the turnout), against the ban on huntings with dogs (nearly three times as many) and both pro and anti Brexit. It was by far the largest the far right has been able to organise, but they only managed that by labelling it a march for free speech (I do think there is a genuine problem with free speech in the UK, and I wish we had the sort of protections the US does).

We all have been tricked to be sick of "social justice" as it has been purposefully exploited to exhaustion until no one cares any more. This is the same method and rhetoric applied through history.

No one measures how far megariches are getting from common folks and just point the guns where they can see because they are led through mediatic misformation campaigns.

It does not need to be a convoluted plan, but it is an opportunity where those same ones are using to sell their guns (oops I mean AI).

You all be killing each other very soon because you are believing in such campaigns for creating "the enemy".

There is no "enemy" who is worried if they'll be able to feed their kids tomorrow. You are being manipulated.

Without AI, it was really hard to get to understand some docs. Today if you don't use AI for these situations shrugs

Most cases it is not that docs author forgot users wont have same toolchains. Simply do not bother reducing config files to share just source code. Indirectly pushing users to make use of same tools.

Hopefully in 20 years no one will be going to check the source code of anything, and programming is elevated even more.

50 years is crazy amount of time, to stay this primitive. Tech shouldn't just evolve for end users.

This is the key.

Germany founded the Federal Constitutional Court of Germany (Bundesverfassungsgericht) to make sure they don't go Fascist again.

The US needs a similar structure with similar protections (term limits, mandatory retirement age, 2/3 majority needed for nominations and shared power of naming the members).

And it's explicitly a court for constitutional matters, not random cases.

Why would I think that? I just dislike how Americans refuse to criticize their own side when they do bad things and I feel that is the biggest problem you have.

Most people don't switch side over small differences, so as long as Democrats continue to follow Republicans into becoming worse and worse nothing will change.

And why do I complain about Democrats? Because you should try to convince the reasonable one, you can't change Trump, but you can maybe change Democrats. But as long as Democrats continue to play along you are doomed, if not this term it will be the next or the one after that, but at some point it will happen.

And no, no amount of "Trump is the devil, see all he has done" will make people stop voting for him. You have to improve the democrats, not throw more shit at Trump. The 2024 election was lost by the Democrats, it was not won by Trump. Trump didn't get more votes in 2024 than 2020, but he won anyway since democrats got so many fewer votes.

- Your summary section should be 1-2 paragraphs that summarize your experience and skills in a narrative format. Not a list of specific things you accomplished. Something like, "Experienced developer with 10+ years of experience at a variety of startup companies writing Python..."

- Those specific accomplishments should be listed under each of your jobs, and there should be no more than 3-4 per job. Right now you have too many things listed under each job, and at least 50% of them are irrelevant

- Don't list all of your jobs in one place at the top of the Experience section.

- In general, the formatting feels very cramped and difficult to read. You need to give each section more white space. Write out the full month and year, not "Feb '19". And the spacing with commas and parentheses you have in these sections is not correct:

Funded Startup(100 people) - Noida, India/Vancouver,Canada

- Your independent projects section doesn't have much information. You need to explain what that site/project is, not just give its name.

It is very unlikely that Israel will ever withdraw its 500,000 citizens from Judea and Samaria, given the result from the 8,000 citizen withdrawall from Gaza.

An equal territorial exchange is much more realistic, as part of a two-state comprehensive package. However, "63% of Palestinians, 65% of Israeli Jews, and 13% of Israeli Arabs are opposed to this two-state comprehensive package.', see https://pcpsr.org/en/node/989 .

Yeah.. About that ... What is a "native Brit"? A white person? Isn't a 2nd or 3rd generation Londoner from Muslim or catholic background with non white skin a British?

I can't see how it was calculated but if you check government numbers, legal migrants are less than a 1% and illegal are not even close to that.

If you are worried about how much they cost, I'm sure they are less than the war in Russia, or many of the electoral campaigns for sure.

Are you sure this info is unbiased and well curated?
