If my fellow Americans hated the rich people that are responsible for all of these homeless individuals half as much as they do said homeless then American wouldn't be half as fucked as it is right now.

The homeless problem is all downstream of shit like the Sacklers pushing opioids and creating millions of addicts for profit. Yet they avoided jail and even can start up new businesses.

The only bad things in the daily NK life you mentioned are poverty and inequality (more about that below [0]). You did not mention famine, physical oppression, lack of healthcare, censorship-all of which are well documented. I am afraid it is not me who is pushing some type of propaganda…

[0] about inequality in communist countries- these countries had much less inequality than western countries. Almost everyone was equally poor. In my home country of Romania the top 100 level apparatchiks (people who rworked directly with Nicolas Ceausescu) had the life style of a surgeon or wealthy dentist in the west: they had a “villa” with 3-4 bedrooms in the Primaverii neighbourdhood and a cottage somewhere. They still had to drive their own Romanian Dacia car. They had good heating and the electrical blackouts did not happen in their neighborhood. They had access to special stores to buy food( they did not wear western clothing). The rest 99.99% of Romanian people were all equally poor: they lined up at the same food queues, lived in the same cold apartments, lacked electricity and medicines equally, drank the same yellow/ brown tap water, listened to the same 2 or 3 western radio stations broadcasting in Romania, etc…

Stalin and the members of his governments also did not live lavishly: Stalin always wore a military coat and all through the 80s the Kremlin looked as drab as ever. His dacha had 4 bedrooms and two floors.

Compare this inequality vs what has been going on in the west. Wealthy people in the west own islands: both Google guys, JP Morgan, the Bush family. They own not just 1 yacht, but another one to follow along with their help on the summer Mediterranean milk-run. They own not just one mansion, but multiple mansions.

I want to conclude this long post by saying that under communism I was personally aware of this difference between the inequality in the west and the equality in communist Romania. And that once Romania overthrew their dictator and inequality exploded I personally felt much better. Sure, 2 or 3 of my classmates started driving to high school in their BMWs-and I spent all of high school in the same patched up jacket. The rich boys had their group physically close and yet separated from us. They were sure to tell girls how much their latest gizmo costed or how big the disco bill from previous night was. Of course they did that in front of poor guys like myself(labagii) All of which is not nice at all. But at least now I had food, heat and electricity-and a chance to leave for better places. I would take this trade-off today just as eagerly as I took it in Dec 89.

>There's a close to 0% chance that I'm never going to bother look at their contents.

More likely scenario, your children, grandchildren or other family members go through your shit after you pass away and discover stuff about you that perhaps you never wanted to share.

This is something I think about a lot because I don't have a "digital legacy plan."

>The term goes back to the 1970s or the late 1960s, and was invented by the puppeteers on Sesame Street. It's documented.

Where, exactly, is this "documented?"

Perhaps my Google(well, DDG, actually)-Fu is deficient as I was unable to find any links to "analingus with a reach around" associated with Sesame Street. The only broadcast media references I could find were radio and movies references from the 2000-2010 period.

As such, please do let me know where to find this documentation. I'd really appreciate it. Thanks!

> Really fixing it would put a double digit percentage of people out of work. I'm all for it, but I can see why politicians are hesitant.

I'd love to hear what you think "really fixing it" is, please share.

I can report that all (almost all?) of the hospitals and their networks both big and small in the area I am in have had layoffs this year of admin staff and healthcare professionals (nurses, doctors, etc). They have reduced bed counts, and cut programs and treatment options available. All of this was done in the name of the "affordability crisis" and is kind of like the 3rd wave of this kind of consolidation, belt-tightening behavior. And..prices haven't gone down, and they keep cutting.

Since we're pretending to know logical fallacies, your deflecting with a slippery slope. Lowering the speed limit by 20 mph is not an extreme change, and it if demonstrates to improve car safety then yes blood should be on your hands for not wanting to drive 20 mph slower.

Alternatively, driving is sometimes necessary to deliver goods and travel. But the funny thing is, is that I would GLADLY ban cars in all cities and heavily invest in high speed rail. Cars would still be needed in this world, but again it's the relative change.

So no, it's not a strawman. If anything it was an ad hom.

See "Induction systems"[1] The concept was proposed in 1963, but nobody ever made it work. That's the plan. Magnetohydrodynamic generators [2] do work, but they have electrodes in the gas. That works for jet engine type MHD generators, but fusion plasma is too hot for any solid material.

What they're trying to do is known physics but very hard engineering.

They're also trying for aneutronic fusion, using helium-3. If the plant generates large volumes of neutrons, it chews up the first wall between the reaction and the outside. It also makes what it hits radioactive, so there's a waste problem. Aneutronic fusion uses reactions that (mostly) generate alphas and betas. This is, again, known physics but very hard engineering.

If they can get a demo machine going which solves either problem, that would be a huge advance. So far, that does not seem to have happened.

There are other startups in this space. It's probably the way commercial fusion power will eventually be done. Not via the tokamaks, like ITER.

From their Wikipedia page

> Energy is captured by direct energy conversion that uses the expansion of the plasma to induce a current in the magnetic compression- and acceleration – coils. Separately it translates high-energy fusion products, such as alpha particles directly into a voltage. 3He produced by D–D fusion carries 0.82 MeV of energy. Tritium byproducts carry 1.01 MeV, while the proton produces 3.02 MeV.

> This approach eliminates the need for steam turbines, cooling towers, and their associated energy losses. According to the company, this process also allows the recovery of a significant part of the input energy at a round-trip efficiency of over 95%.

I've been using Claude Code with Serena MCP, but for the past few weeks it's been compressing the context more often. I have two Pro accounts, and it's still not enough for my daily needs anymore :(

Also, Claude Code tends to make very broad search requests, and I keep getting an error from MCP about exceeding 25,000 characters. It happens quite often.

What would you recommend?

Same reason I don't want to have dinner in a restaurant next to someone trying to cut their steak with a chainsaw: at best they are being incredibly obnoxious, at worst they are going to maim me. Just because it is better for your once-a-month weekend lumberjack trip with the boys doesn't mean it is an appropriate one-size-fits-all cutting tool for day-to-day use.

Contrast that with someone having a needlessly powerful computer. How does that impact the rest of the world? Not at all, it only impacts the owner's wallet. Someone's needlessly-powerful computer has never killed a child, or taken up four spots in public. Heck, it'll even downclock when idle, so there isn't even any extra power use to be worried about!

The problem is that the agreement does not seem to specify that the electricity has to come from fusion![1] This is actually common in renewable PPAs - if the specific project doesn't come online then the provider has to find an alternative. But those are usually done with established providers which have > 0MW overall capacity. Helion does not. If the PPA is fixed amount vs fixed price, Microsoft might end up on the hook for inflated wholesale prices instead of cheap fusion.

FWIW I agree with the author of that Data Center Dynamics post, it's quite likely that MSFT and Helion are essentially in cahoots by stoking investors with vaporware. But it also seems like Altman might have sold Nadella 50MW of magic beans.

[1] https://www.datacenterdynamics.com/en/opinions/microsoft-and... This is second-hand, the agreement is not public.

That's irrelevant. The price is what one pays, whether that's residential, commercial, or industrial. Typically only industrial users have any negotiating power, and typically residential customers are the only users who aren't able to claim the expense as a business operating cost.

There's an argument to be made that in a democracy the people could vote themselves lower taxes, but if that were the cast why haven't they already.

Subsidies are paid for by tax payers anyway, so, ya know, TANSTAAFL - There Ain't No Such Thing As A Free Lunch. And there's no guarantee subsidies survive the next election.

You are responsible for the layers. You should either do the design on your own, or let the tool ask you questions and guide you. But you should have it write down the plan, and only then you let it code. If it messes up the code, you /clear, load the plan again and tell it to do the code differently.

It's really the same with junior devs. I wouldn't tell a junior dev to implement a CRM app, but I can tell the junior dev to add a second email field to the customer management page.

Other places have introduced the same limit and haven't seen the same results.

People who are likely to have crashes are likely to be able who ignore the limit. One of the biggest problems in modern policy-making is the introduction of wide-ranging, global policies to tackle a local problem (one place that introduced this limit was Wales, they introduced this limit impacting everyone...but don't do anything about the significant and visible increase in the numbers of people driving without a licence which is causing more accidents...and, ironically, making their speed limit changes look worse than they probably are).

I've been developing AI apps for the past year and encountered a recurring issue. Non-tech individuals often asked me to adjust the prompts, seeking a more professional tone or better alignment with their use case. Each request involved diving into the code, making changes to hardcoded prompts, and then testing and deploying the updated version. I also wanted to experiment with different AI providers, such as OpenAI, Claude, and Ollama, but switching between them required additional code modifications and deployments, creating a cumbersome process. Upon exploring existing solutions, I found them to be too complex and geared towards enterprise use, which didn't align with my lightweight requirements. So, I created Hypersigil, a user-friendly UI for prompt management that enables centralized prompt control, facilitates non-tech user input, allows seamless prompt updates without app redeployment, and supports prompt testing across various providers simultaneously.

The world differs greatly when it comes to socially acceptable (or even legal) honking. In Sweden barely anyone honks unless to avoid serious accidents. In Spain, there is some honking, even when you just mildly inconvenience someone. In Peru, honking is a way of life/driving, and to communicate with other drivers, even when you just pass someone normally.

No. A phantom type is a type whose only use is to communicate a constraint on a type variable, without having a runtime value that corresponds to it.

Typestate is a bit closer: it communicates some property where an operation (typically a method invocation) changes the property and hence the typestate. But there isn't necessarily a mechanism that renders the value in the old typestate inaccessible. When there is, then this indeed requires some linearity/affinity ("consuming the object"), but typestate is something built "on top".

https://en.wikipedia.org/wiki/Magnetohydrodynamic_generator is the gist of it. If you have enough conductive plasma then just moving it through a magnetic field generates a current. Applied to fusion power, you heat the plasma through the fusion reaction then divert part of the plasma through the MHD generator.

Tbh, I very much doubt that this is a realistic path in the coming decade (but would love to be proven wrong). AFAIK no experimental reactor has yet generated any net electrical power at all, let alone with any big (ie dozens to hundreds of) MW MHD generators. Getting even one of these aspects working would be a major advance, let alone doing both at once.

> you've fallen into the far right rabbit hole, and this is what "catch you when you say something they don't like" means

It might be true for this particular person, but people being a live minefield waiting to blow up in your face is more general experience. Regardless of your views, no matter how benign and out of mainstream controversy you perceived them to be, they will be taken as a reason to view you negatively by someone you know and sever or at least degrade the connection. People can mostly tolerate each other because they share very limited slice of themselves.

If you trip on such snag with AI you can just start another chat session. With people you basically need to find and befriend another person.

As someone who lives and regularly drives in Helsinki, I feel that most kilometers I drive are on roads that allow 80km/h. The 30km/h limits are mostly in residential areas, close to schools and the city center (where traffic is the limiting factor and it's better to take the public transit).

So while 30km/h might be the limit for most of the roads, you mostly run into those only in the beginnings and ends of trips.

The elephant in the room is that NIMBYs are powerless in Japan.

In the US, people value individuality. In Japan, they have this saying: If a nail sticks out, hammer it flat. NIMBYs are ostracized for being a burden on society.

No matter if the neighbors like it or not, houses regularly get bulldozed to build new high-rise apartment buildings instead. Replacing a single family home with a 20-floor skyscraper easily 50x-es number of available apartments on the market, thereby massively pushing prices down.

I don't think this generalization is quite fair. I'm sure this is true for some folks and their social circles, but for those of us who engineer and know our way around a Home Depot, the capacity is a game changer. I used to have to rent or borrow trucks for my projects.

Not to mention Christmas trees, moving, helping friends out, etc.

At least the Fiat Multipla was a great car. It is filled to the brim with small features which improve the driving experience, and it is a miracle that it can fit six(!) people. It has a massive amount of storage space and great visibility, what's not to like?

Besides the way it looks, of course. But if you're inside a Multipla, at least you don't have to look at its exterior?

While I'm a bit atypical in tolerating loneliness, if it's a problem for people then I think AI is not the solution, or any soulless computer system really. Loneliness in the human social space is usually balanced, lonely people will meet in pairs or groups and cancel out their loneliness. This people-based system is somewhat resistant against abuse because people are pairwise interested in keeping the system going. (Of course there are spies and such who prey on emotions but they're not common as far as I know.)

With AI, the meta changes and suddenly you must pay for system. The system could start jacking up prices or punitively denying politically unpalatable people their loneliness treatment simply because of the prevailing social forces. Especially if ekeing out more profit over time is the true objective, providing the social good of allaying loneliness will become secondary. I don't see this as a good thing. It is basically an AI form of drug dealing with extra steps.

I creates something similar in concept but with different goal. I wanted to be able to watch videos with sponsor block on iPad ideally using Plex.

I found self hosted solution like this but I was very dissatisfied with how that worked

on other hand I wanted to check out loco.rs framework, so I decided to implement my own solution.

basically you are able to add channels/playlists on many many platforms that yt-dlp supports, you can select what should be cut out using sponsor block and you choice how many days you want it (videos older that that are automatically deleted)

> Speed traps (that's probably what is talked about here) are a very targeted from of surveillance, only taking pictures of speeding vehicles.

Speed cameras in practice will use ALPR, and by the time the hardware capable of doing ALPR is installed, they'll then have the incentive to record every passing vehicle in a database whether it was speeding or not, and whether or not they're "allowed" to do that when the camera is initially installed.

It's like banning end-to-end encryption while promising not to do mass surveillance. Just wait a minute and you know what's coming next.

it's been a long time since i used screen. afaik screen had one session per process. you could switch processes by detaching from one and attaching to another. in tmux it's all one process, which allows you to create new sessions and switch them interactively and move windows from one session to another, or even have a window in more than one session. i can also see all windows from all sessions:

(0) - main: 6 windows (1) ├─> 0: elvish- (2) ├─> 1: elvish*: "[mosh] embee@foo:~" (3) ├─> 2: elvish (4) ├─> 3: elvish: "embee@bar:~" (5) ├─> 4: elvish: "[mosh] embee@fedora:/etc" (6) └─> 5: elvish (7) - local: 6 windows (attached) (8) ├─> 0: elvish (9) ├─> 1: elvish- (M-a) ├─> 2: [tmux]* (M-b) ├─> 3: elvish (M-c) ├─> 4: elvish (M-d) └─> 5: elvish (M-e) - dev: 7 windows (attached) (M-f) ├─> 0: elvish* (M-g) ├─> 1: elvish- (M-h) ├─> 2: elvish (M-i) ├─> 3: elvish (M-j) ├─> 4: elvish

That’s underselling the community around it. Most subsystems have dedicated maintainers at this point, and it’s improving at a reasonable rate. It’s just new and new tools don’t have the full set of features of older tools.

I’m assuming based on your dismissal of people using a new terminal emulator instead of one which has been around for decades, that you don’t want any time or effort invested in new tools.

Just a few months ago I couldn't imagine paying more than $20/mo for any kind of subscription, but here I am paying $200/mo for the Max 20 plan!

Similarly amazed as an experienced dev with 20 YoE (and a fellow Slovak, although US based). The other tools, while helpful, were just not "there" and they were often simply more trouble than they were worth producing a lot of useless garbage. Claude Code is clearly on another level, yes it needs A LOT of handholding; my MO is do Plan Mode until I'm 100% sure it understands the reqs and the planned code changes are reasonable, then let it work, and finally code review what it did (after it auto-fixes things like compiler errors, unit test failures and linting issues). It's kind of like a junior engineer that is a little bit daft but very knowledgeable but works super, super fast and doesn't talk back :)

It is definitely the future, what can I say? This is a clear direction where software development is heading.

Have it generate the code. Then have another instance criticize the code and say how it could be improved and why. Then ask questions to this instance about things you don't know or understand. Ask for links. Read the links. Take notes. Internalize.

One day I was fighting Claude on some core Ruby method and it was not agreeing with me about it, so I went to check the actual docs. It was right. I have been using Ruby since 2009.
