I am not sure on what your commented is based on, but in short: No? High performance software needs to deal with memory, and optimisations often will need some kind of direct control - as in this example where re-using memory is more performant than constantly churning with mmap.
A lot of developers use the terminal as their primary interaction with the computer. Nvim, tmux, etc. Having it be fast is an extreme quality of life improvement. For devs who only ever use the terminal integrated into their ide then it’s probably less important.
not the same person but in the flow of doing things those little pauses (tens of milliseconds) do matter. I open/close nvim (and less-so tmux) a ton, and run lots of commands per day. I don’t want to wait
and once you get used to things being that fast, it’s hard to go back (analogous to what people say about high-refresh screens/monitors)
all that said the speed of the default mac terminal (and other emulators I tried) was always fine for me, performance was not why I switched to Ghostty
I think this kind of thing just bothers some people and not others.
I first started to understand and notice update rates and responsiveness as a gamer playing 1st person shooters.
I hate (ok, I find it a bit jarring) the jerky scrolling of a phone in battery save mode limited to 60(?) FPS. It’s so obviously not connected to your touch anymore.
In terminals it’s things like the responsiveness fuzzy finders and scrolling that I really notice.
I turn off animations everywhere I can.
It’s not impossible to use something slower, but when everything feels instant it’s just much more pleasant, smoother, and feels more productive as a result of the computer working at whatever speed my brain does.
Well, perhaps “performant” isn’t the word you should be using. All code should be performant, where performant is defined as performing at an acceptable level. You might be tempted to then ask if it needs to be ultra high performance? That’s a better question but still off the mark. The correct question is whether YOU need an ultra high performance terminal emulator? If you don’t, you’re free to not use it. I haven’t found a need for it myself, for instance, and I still use the vanilla MacOS term. But that doesn’t mean someone else hasn’t wanted a faster term than the MacOS term and I wouldn’t throw shade on them for scratching that itch, even if I don’t share it.
> Ghostty is a terminal emulator that differentiates itself by being fast, feature-rich, and native. While there are many excellent terminal emulators available, they all force you to choose between speed, features, or native UIs. Ghostty provides all three.
> In all categories, I am not trying to claim that Ghostty is the best (i.e. the fastest, most feature-rich, or most native). But when I set out to create Ghostty, I felt all terminals made you choose at most two of these categories. I wanted to create a terminal that was competitive in all three categories and I believe Ghostty achieves that goal.
> Before diving into the details, I also want to note that Ghostty is a passion project started by Mitchell Hashimoto (that's me!). It's something I work on in my free time and is a labor of love. Please don't forget this when interacting with the project. I'm doing my best to make something great along with the lovely contributors, but it's not a full-time job for any of us.
You've missed all the posts where people complain about a terminal emulator taking 1ms longer to respond to a keystroke than their preferred one, haven't you?
Windows 11 makes me hate everyday computing. From the adverts in the start menu, to the sluggish performance on a computer orders of magnitude more powerful than any XP machine I used. It's just not fun anymore.
American free speech as of 2026 includes openly threatening to invade European territory unless it is given away.
It's funny how America can force it's own crappy content protection laws to the entire globe, but another country can't have their own.
The current administration is burning good will to America with it's allies at an alarming rate. This isn't good for stability or world order. I think this year is could be a contender to be the worst one yet of this millennium as we find other despots empowered by America's actions.
I'm not sure I have ever seen such an unprofessional communication from the CEO of Cloudflare, irrespective of a poorly written Italian law.
The fine was also peanuts for a company the size of Cloudflare.
Given the current political climate I think the tone he is using will turn a lot of Europeans off: Open threats against citizens of an EU country (turning off free cyber protections) and general 'American Exceptionalism' attitude and brown nosing of the current administration.
He is within his rights to pull out of a market, but this is an example of the now-becoming-classic Trumpism of smugly shouting pretty extreme open threats to bully your way into getting what you want (and screw everyone else who isn't America).
It honestly makes me want to add it to the list of American tech companies willing to sabotage Europe for disproportionate reasons. (Currently X, Microsoft) and start planning strategies to decouple from them, if not outright replace.
Perhaps this is a knee-jerk reaction, but I was not expecting this from Cloudflare.
the fine being 2x revenue from italy is not peanuts. The threat to leave the country is more than fair. If we are talking about sabotaging europe we should focus in the first place on chat control laws and how those slowly slip into adoption...
> Perhaps this is a knee-jerk reaction, but I was not expecting this from Cloudflare.
You’re surprised that an American CEO is speaking out against a large fine many believe is bogus, instead of not saying anything to avoid offending…Europe? I don’t think anyone in the world right now is intimidated by the EU, from China to the US to Russia.
> these days anyone who says "I support Palestine Action"
They have a video of people from this group attacking police with sledgehammers. It is strange how much of this 'direction action' is harming Ukraine support and not Israel. If people wanted to support Palestine they can do it without attacking their own countries' military - which is not operating in Israel at all.
> "she was murdered by ICE"
They have a video of her being shot, pretty much needlessly. I'd say that should be manslaughter at a minimum.
"They have a video of people from this group attacking police with sledgehammers"
Do you have the name or names of the person accused of 'attacking police with sledgehammers'?
I've heard a lot about this, but it's difficult to get to actual sources about exactly what is alleged.
Even if this did happen as you say. attachking police with sledgehammers is assault, potentially even attempted murder. There's plenty of laws for that.
> Do you have the name or names of the person accused of 'attacking police with sledgehammers'?
You should be less flippant.
The accused's name is Samuel Corner. He and his friends are still on trial for their actions.
Here's the bodycam footage where you see Samuel Corner attack police seargent Kate Evans with a sledgehammer while she was on the ground, fracturing her spine. Watch from 3m05s to 3m10s:
The group's stated aim is to stop the UK or any UK companies giving Israel any military support. They target companies who they think supply Israel. They break in and smash them, and as you've hopefully just seen with your own eyes, they are not afraid to attack people with sledgehammers. They use violence to achieve their political aim. They are terrorists and belong in prison.
> Samuel Corner, 23, [...] Oxford University graduate from Devon [...] when asked why he struck Sgt Evans with the sledgehammer, he replied: "It was me not really knowing what I was doing
Thanks Samuel. That Oxford degree really shows, doesn't it?
It feels to me like there's a distinction between "on one occasion, one person in group X did Y" and "group X does Y", and it's the second of those that (for some choices of Y, including "attacking police with sledgehammers") could justify calling group X a terrorist group.
Obviously "on one occasion, a person in group X did Y" is evidence for "group X does Y". If Samuel Corner attacked a police sergeant with a sledgehammer during one Palestine Action, er, action, then that's the sort of thing we expect to see more often if PA is generally in favour of attacking police with sledgehammers. (Either as a matter of explicit open policy, or as a nudge-nudge-wink-wink thing where everyone in PA knows that if they start smashing up police as well as property then their PA comrades will think better of them rather than worse.)
But it falls way short of proof. Maybe Samuel Corner sledgehammered a cop because Palestine Action is a terrorist organization after all; but maybe Samuel Corner sledgehammered a cop because Samuel Corner is a thug or an idiot or was drunk or whatever. Or maybe Samuel Corner sledgehammered a cop because the cops were already being violent with the Palestine Action folks and he was doing his (ill-advised) best to protect the others from the police. (This, as I understand it, is his account of things.)
(An Oxford University graduate attacked a police officer with a sledgehammer. I take it you would not say that that makes the University of Oxford a terrorist organization, and you wouldn't say that even if he'd done it while attending, say, a university social function rather than while smashing up alleged military hardware. It matters how typical the action is of the organization, what the group's leadership thinks of the action, etc.)
I took a look at the video. It's not easy to tell what's going on, but it looks to me as follows. One of the PA people is on the ground, being forcibly restrained and tasered by a police officer, complaining loudly about what the police officer is doing. (It isn't obvious to me whether or not her complaints are justified[1].) There is another police officer, whom I take to be Kate Evans, nearby, kneeling on the ground and helping to restrain this PA person. Samuel Corner approaches with his sledgehammer and attacks that second police officer. I can't tell from the video exactly what he's trying to do (e.g., whether he's being as violent as possible and hoping to kill or maim, or whether he's trying to get the police officer off the other person with minimal force but all he's got is a sledgehammer).
[1] I get the impression that she feels she has the right not to suffer any pain while being forcibly restrained by police, which seems like a rather naive view of things. But I also get the impression that the police were being pretty free with their tasering. But it's hard to tell exactly what's going on, and I imagine it was even harder in real time, and I am inclined to cut both her and the police some slack on those grounds.
It's highly misleading, even though not technically false, to say that Corner attacked Kate Evans "while she was on the ground"; she certainly was on the ground in the sense that she was supported by the floor, and even in the sense that she wasn't standing up -- I think she was crouching -- but it's not like she was lying on the ground injured or inactive; she was fighting one of the other PA people, and she was "on the ground" because that PA person was (in a stronger sense) "on the ground" too.
For the avoidance of doubt, I do not approve of attacking police officers with sledgehammers just because they are restraining someone you would prefer them not to be restraining, even if you think they're doing it more violently than necessary. And I have a lot of sympathy with police officers not being super-gentle when the people they're dealing with are armed with sledgehammers.
But the story here looks to me more like "there were a bunch of PA people, who had sledgehammers because they were planning to smash up military hardware; the cops arrived and wrestled and tasered them, and one of the PA people lost his temper and went for one of the cops to try to defend his friend whom he thought was being mistreated, and unfortunately he was wielding a sledgehammer at the time" than like "PA is in the business of attacking cops with sledgehammers".
None of that makes Kate Evans any less injured. But I think those two possibilities say very different things about Palestine Action. Carrying sledgehammers because you want to smash equipment is different from carrying sledgehammers because you want to smash people. Attacking police because they are a symbol of the state is different from attacking police because they are attacking your friend. One person doing something bad in the heat of the moment because he thinks his friend is being mistreated is different from an organization setting out to do that bad thing.
There are plenty of documented cases of police being violent (sometimes with deadly effect) with members of the public. Sometimes they have good justification for it, sometimes not so much. Most of us don't on those grounds call the police a terrorist organization. Those who do say things along those lines do so because they think that actually the police are systematically violent and brutal.
I think the same applies to organizations like Palestine Action. So far as I can tell, they aren't systematically violent and brutal. Mostly they smash up hardware that they think would otherwise be used to oppress Palestinians. (I am making no judgement as to whether they're right about that, which is relevant to whether they're a Good Thing or a Bad Thing but not to whether they're terrorists.) Sometimes that leads to skirmishes with the police. On one occasion so far, one of them badly injured a police officer. It's very bad that that happened, but this all seems well short of what it would take to justify calling the organization a terrorist one.
> The group's stated aim is to stop the UK or any UK companies giving Israel any military support. They target companies who they think supply Israel.

Yet none of them are being prosecuted under the terrorism act, or on any charge related to terrorism.
I think they meet the definition of "terrorists" by their stated goals and acts. But it seems there's reticence by the CPS to break out the Terrorism Act.
Palestine Action is already a proscribed group because of spraypainting RAF planes. I would say this raid seems more terroristic than base invasion, but what do I know? I'm not the Home Secretary.
It raises questions, because while the Terrorism Act is heavily criticised for being overbroad and making a number of otherwise innocuous things crimes, the CPS haven't used it against this group of people, who'd face prison just for being a member, or claiming to be a member of Palestine Action. Maybe the CPS can't reliably prove they are?
> "My friends were in danger and they [the police] were getting quite hands-on.
They were petulantly resisting arrest (it looks on camera to scream instead of just complying calmly) while committing destructive/violent crimes. The police were very restrained here. There was no danger from the police, at all.
Now a police officer doing their job has a spinal injury. Palestine Action says they will not stop doing 'direct action' (sabotage, property destruction, violence). They deserve the proscription.
> The quote from the article continues. You cut it off.
I quoted three separate snippets from the article that I wanted to draw attention to, and gave you the URL to read the rest yourself.
I'm of the opinion that, someone who sledgehammers an unaware opponent and claims in their defense "I was just trying to help", they are being disingenuous. Especially as one of Britain's most elite and privileged youngsters.
If you'd like to quote more of the article:
> When asked by his barrister Tom Wainwright whether he was willing to injure a person or use violence during the break-in, he replied: "No, not at all".
Read that back to yourself while watching the attack footage again. Is this credible testimony?
Wow, thanks. It was really shameful for amiga386 to intentionally hide that critical context. They even omitted the comma showing that there was additional context (and replaced it with inappropriate snark).
I find it horrifying (though not surprising) how many people can assume that just because you express some level of support for a group, you are complicit in all actions taken by that group.
In the extreme, that sort of view makes it impossible to have criminal lawyers.
(And not far below that extreme, we have people using all their power to go after independent judges and lawyers with every extrajudicial tool at their disposal, legal system be damned.)
The nuance between speech and action was one of the many casualties of social media. I wonder if, back in the 90's, people would get arrested for holding "FREE KEVIN MITNICK" posters, if we'd had two decades of social media before it.
UK military is operating in Palestine (very frequent military flights from their post-colonial base in Cyprus), and is operating in Israel (when they were shooting down drones, etc.), and is supplying Israel with weapons (directly by soldier training and indirectly by allowing to use their military bases), and joined in international coverup (they have detailed intelligence on what Israel was doing in Gaza, which they never released publicly any part of).
Pretty solid basis for direct action.
If they provided this level of support for Russia, they'd be a new Belarus.
Equating surveillance flights off the coast with "operating in the country" is tenuous at best. If that's the threshold, Russian military is already operating in Britain (see Yantar's adventures).
The mental effort a lot of people has made to pretend they aren't entirely powerless and irrelevant for stopping Israel's crimes is deeply impressive. The reality is that there's nothing the UK can do to stop Israel as long as the US is supporting them (short of going to war with both the US and Israel), but this reality is at odds with the desire to do something, so people invent and inflate leverage where there isn't any. Moreover, most of the time the very same people oppose creating more leverage for the future, as your added qualifier of "post-colonial" implies. It's depressing.
It's not off the coast, they're circling directly over the territory of Palestine, without invitation from Palestinian state, and against interests of Palestinians.
Post-colonial only implies that Cyprus was a UK colony, and now is not, but still retains some bases in there.
Not direct intervention; but we fly sorties, provide intelligence, ship military equipment, build systems for... None of which we provide Israel for their current war.
It's just odd to me that Israel draws so much Ire when the UK deals with all sorts. There are many worse things happening that doesn't get a second of airtime.
Not that your comment is relevant, but why is there a narrative of obstruction when you can visibly see Renee Good wave another truck by moments before she was killed?
The newly released footage is truly a political Rorschach test. It is unbelievable to me that anyone without diminished mental capabilities could believe that exonerates the camera man.
If I recall correctly this was in direct response to British citizens being kidnapped and held hostage inside Gaza. These were intelligence sorties with the express aim to help locate UK citizens.
So UK citizens were not kidnapped? Or are you implying the UK were not doing intelligence flights, but were attacking Gaza directly, or had boots on the ground directly? Because I have seen absolutely zero reporting to infer that.
Like all defenders of the indefensible, you will shift the goalposts incessantly to suit the narrative you wish to defend.
First it was, "The British military isn't doing anything in Gaza, anyone who says otherwise is lying."
Now it is, "The British military might be doing something in Gaza, but they're justified in doing so, and it's limited to protecting British citizens anyways."
What will it be now?
"While the Ministry of Defence (MoD) claims these flights are solely for locating Israeli hostages held by Hamas, AOAV found that the RAF conducted 24 flights in the two weeks leading up to and including the day of Israel’s deadly attack on the Nuseirat Refugee Camp on 8 June 2024, which killed 274 Palestinians and injured over 700."
"On October 19, 2024, four days after it had been at RAF Brize Norton, the “Re’em” aircraft with registration 272 appeared directly over Gaza at 7:32 p.m. local time, less than 5km away from Beit Lahiya, a city in north Gaza. Three hours later, at 11:20 p.m., the IAF bombed a residential complex in Beit Lahiya killing at least 73 people.
On October 24, 2024, nine days after traveling to the UK, the same 272 aircraft was located at 9:30 p.m. less than 5 miles from Jabalia camp. An hour later, at 10:40 p.m., airstrikes were recorded destroying apartment blocks in Jabalia. The aircraft remained airborne patrolling the airspace near Gaza until it was recorded at 10:36 p.m. near Ashdod, a coastal city near Tel Aviv, flying towards Hatzor Airbase."
Well the Russian drones are munitions, so that's not comparable. Is the UK dropping bombs on Gaza? I have seen zero reporting to say they have.
The UK might be flying spy planes outside it's airspace when it's citizens were kidnapped. That's not a "combatant". Was the UK a combatant when flying spy planes near the Ukraine border?
I think you are way off the mark based on reporting, I'm not even sure how you are coming to these stated opinions.
No, they're not dropping munitions, they're simply coordinating with the Israeli military to facilitate the dropping of munitions, doing everything possible save putting boots on the ground (that we know of). So you're right, in that case Britain is more like China in this situation, perfectly blameless.

Do you understand the code?
What was the speed up from months to weeks? You just didn't know what to type? Or you didn't know the problem domain? Or you found it hard to 'start' and the AI writing boiler plate gave you motivation?
In my experience with AI tools, it only really helps with ideation, most things it produces need heavy tweaking - to the point that there is no time savings. It's probably a net negative because I am spending all of my time thinking how to explain things to a dumb computer, rather than thinking about how to solve the problem.
The main advantage is I can run it in parallel and iterate often.
The speed up is also avoiding looking up reference manuals endlessly just to produce some Qt Widgets.
I’m a fairly recent convert, I only started “vibe coding” a couple of months ago, after hearing how good Opus was. I had been a skeptic until then.
I am a decentralist by nature and prefer open standards and self hosting. I’ve had my own *nix servers since I was twelve (nearing forty) so it really pains me to admit how good it is to use these corporate products.
I am not a programmer by trade.
I use it to write software for my domain of expertise. The value of what I am creating is enormous.
Both ChatGPT and Claude produce good code, in my opinion.
> It’s a bit strange how anecdotes have become acceptable fuel for 1000 comment technical debates.
It's a very subjective topic. Some people claim it increases their productivity 100x. Some think it is not fit for purpose. Some think it is dangerous. Some think it's unethical.
Weirdly those could all be true at the same time, and where you land on this is purely a matter of importance to the user.
> Yet, I’d love to see less discussion driven by anecdotes and more discussion about productizing these tools, where they work, usage methodologies, missing tooling, KPIs for specific usecases. And don’t get me started on current evaluation frameworks, they become increasingly irrelevant once models are good enough at instruction following.
I agree. I've said earlier that I just want these AI companies to release an 8-hour video of one person using these tools to build something extremely challenging. Start to finish. How do they use it, how does the tool really work. What's the best approaches. I am not interested in 5-minute demo videos producing react fluff or any other boiler plate machine.
I think the open secret is that these 'models' are not much faster than a truly competent engineer. And what's dangerous is that it is empowering people to 'write' software they don't understand. We're starting to see the AI companies reflect this in their marketing, saying tech debt is a good thing if you move fast enough....
This must be why my 8-core corporate PC can barely run teams and a web browser in 2026.
How many 1+ hour videos of someone building with AI tools have you sought out and watched? Those definitely exist, it sounds like you didn't go seeking them out or watch them because even with 7 less hours you'd better understand where they add value enough to believe they can help with challenging projects.
So why should anybody produce an 8 hour video for you when you wouldn't watch it? Let's be real. You would not watch that video.
In my opinion most of the people who refuse to believe AI can help them while work with software are just incurious/archetypical late adopters.
If you've ever interacted with these kinds of users, even though they might ask for specs/more resources/more demos and case studies or maturity or whatever, you know that really they are just change-resistant and will probably continue to be as as long as they can get away with it being framed as skepticism rather than simply being out of touch.
I don't mean that in a moralizing sense btw - I think it is a natural part of aging and gaining experience, shifting priorities, being burned too many times. A lot of business owners 30 years ago probably truly didn't need to "learn that email thing", because learning it would have required more of a time investment than it would yield, due to being later in their career with less time for it to payoff, and having already built skills/habits/processes around physical mail that would become obsolete with virtual mail. But a lot of them did end up learning that email thing 5, 10, whatever years later when the benefits were more obvious and the rest of the world had already reoriented itself around email. Even if they still didn't want to, they'd risk looking like a fossil/"too old" to adapt to changes in the workplace if they didn't just do it.
That's why you're seeing so many directors/middle managers doing all these though leader posts about AI recently. Lots of these guys 1-2 years ago were either saying AI is spicy autocomplete or "our OKR this quarter is to Do AI Things". Now they can't get away with phoning it in anymore and need to prove to their boss that they are capable of understanding and using AI, the same way they had to prove that they understood cloud by writing about kubernetes or microservices or whatever 5-10 years ago.
> In my opinion most of the people who refuse to believe AI can help them while work with software are just incurious/archetypical late adopters.
The biggest blocker I see to having AI help us be more productive is that it transforms how the day to day operations work.
Right now there is some balance in the pipeline of receiving change requests/enhancements, documenting them, estimating implementation time, analyzing cost and benefits, breaking out the feature into discrete stories, having the teams review the stories and 'vote' on a point sizing, planning on when each feature should be completed given the teams current capacity and committing to the releases (PI Planning), and then actually implementing the changes being requested.
However if I can take a code base and enter in a high level feature request from the stakeholders and then hold hands with Kiro to produce a functioning implementation in a day, then the majority of those steps above are just wasting time. Spending a few hundred man-hours to prepare for work that takes a few hundred man-hours might be reasonable, but doing that same prep work for a task that takes 8 man-hours isn't.
And we can't shift to that faster workflow without significant changes to entire software pipeline. The entire PMO team dedicated to reporting when things will be done shifts if that 'thing' is done before the report to the PMO lead is finished being created. Or we need significantly more resources dedicated to planning enhancements so that we could have an actual backlog of work for the developers. But my company appears to neither be interested in shrinking the PMO team nor in expanding the intake staff.
It could be really beneficial for Anthropic to showcase how they use their own product; since they're developers already, they're probably dogfooding their product, and the effort required should be minimal.
- A lot of skeptics have complained that AI companies aren't specific about how they use their products, and this would be a great example of specificity.
- It could serve as a tutorial for people who are unfamiliar with coding agents.
- The video might not convince people who have already made up their minds, but at least you could point to it as a primary source of information.
These exist. Just now I triedfinding such a video for a medium-sized contemporary AI devtools product (Mastra) and it took me only a few seconds to arrive at https://www.youtube.com/watch?v=fWmSWSg848Q
There could be a million of these videos and it wouldn't matter, the problem is incuriosity/resistance/change-aversion. It's why so many people write comments complaining about these videos not existing without spending even a single minute looking for them: they wouldn't watch these videos even if they existed. In fact, they assume/assert they don't exist without even looking for them because they don't want them to exist: it's their excuse for not doing something they don't want to do.
That video was completely useless for me. I didn't see a single thing I would consider programming. I don't want to waste time building workflows or agentic agents, I want to see them being used to solve real world difficult problems from start to finish.
> How many 1+ hour videos of someone building with AI tools have you sought out and watched?
A lot, they've mostly all been advertising trite and completely useless.
I don't want a demonstration of what a jet-powered hammer is by the sales person or how to oil it, or mindless fluff about how much time it will save me hammering things. I want to see a journeyman use a jet-powered hammer to build a log cabin.
I am personally not seeing this magic utopia. No one wants to show me it, they just want to talk about how better it is.
At least the European laws are debated, and more often than not will then be voted down. America has the similar laws for the state, they're just secret and do not help the average person.
It is also getting harder to argue against descriptive laws on communications when Grok is churning out child pornography and X thinks that's just "the user's fault".
I wonder how hard it would be to get seat belts enshrined in law in the modern day if they never existed. Europe is already throwing out a bunch of safety standards because King Trump wants unsafe American vehicles to be sold in the EU. How about the US stops making crap cars? Oh sorry, that's the "ungrateful" European in me. Trump really is throwing out 80 years of shared progress and proving the anti-US stance that all of it's allies are just vassals.
