> And there it is: You can’t prove it’s not true. “The idea that AGI is coming and that it’s right around the corner and that it’s inevitable has licensed a great many departures from reality,” says the University of Edinburgh’s Vallor. “But we really don’t have any evidence for it.”

That's the most important paragraph in the article. All of the self serving excessive exaggerations of Sam Altman and his ilk, predicting things and throwing out figures they cannot possibly know. "ai will cure cancer, and demetia! And reverse global warming! Just give more money to my company which is a non profit and is working for the good of humanity. What is that? Do you mean to say you don't care about the good of humanity?" What is the word for such behaviour? It's not hubris, it's a combination of wild prophecy and severe main character syndrome.

I heard once, though i have no idea if it's true that he claims he carries a remote control around with him to nuke his data centres if they ever start trying to kill everyone. Which is obviously nonsense but is exactly the kind of thing he might say.

In the meantime they're making loads of money by claiming expertise in a field which doesn't even exist and in my opinion never will, and that's the main thing i suppose.

JIT workaround helps UTM VMs and iSH/ashell (Linux emulation), https://onejailbreak.com/blog/stikdebug-ios/

> StikDebug works around those restrictions by using a local VPN profile to manage the JIT process securely within the app. Once you approve the VPN configuration, StikDebug can communicate with sideloaded apps and activate JIT automatically when you launch them. This means that users on iOS 26 can finally enjoy the same performance benefits that developers used to unlock only through Xcode or jailbreaking.

Continuity is fundamentally a topological property of a mapping. It just means that for a mapping F and a point p, for any neighborhood del of F(p), we can find a neighborhood eps of p such that F(eps) is contained entirely in del. In simpler terms, if you draw a little ball around F(p), I can find a little ball around p whose image under F is contained in the little ball you drew around F(p). If I have coordinates on the sphere that suddenly jump between 0 and 2*pi, I can’t satisfy this property, because points that are arbitrarily close on the sphere will be mapped to opposite sides of the “coordinate square” with sides [0,2*pi).

The Mercator projection is obtained by removing two points from the sphere (both poles) and stretching the hole at each pole until the punctured sphere forms a cylinder, then cutting the cylinder along a line of longitude. So you can see that the 3 discontinuities in the Mercator projection correspond to the top and bottom edges (where we poked a hole at each pole) and the left/right edges (where we cut the cylinder). (Note that stretching the sphere at the poles changes the curvature, but cutting the cylinder does not. The projection would have the same properties on a cylinder.)

It is possible to continuously map the sphere to the entire (infinite) plane if you just remove a single point (the north pole): place the sphere so the south pole is touching the origin of the plane and for any point on the sphere, draw a line from the north pole through that point. Where that line intersects the plane is that point’s image under this mapping (called the Riemann sphere).

It doesn't change anything with their higher tier sales. Those are bought for a reason that a lower tier device cannot satisfy.

My worry (from Apple's POV) is that all the people who buy the cheapest Mac (currently for $1k) will instead go for this new "base model". And I suspect there's a large cohort of people who "just want a Mac".

Fairly confident the CPU has never been the reason you can't install whatever you want on an iOS/iPadOS device. Also not the reason you can't install macOS on it either.

If you want macOS, you buy a Mac. You want iPadOS, you buy an iPad. And if you want an iPad Pro that can double up as a Mac in a pinch, you feel awkward while Tim Cook death stares at you until you empty your pockets.

In all seriousness though, I have an iPad Pro and a MacBook (as a lot of people here do I'm sure) and it would make a poor laptop. And how do you switch between macOS and iPadOS? I don't see a way to have that not be clunky because of all the different metaphors. I'd rather just have both (actually I'd rather just have the MacBook as the iPad sits largely idle, as I'm also sure a lot of people's do).

I travel internationally. These arcane rules also do not affect me.

Me: Lifelong, native-born citizen of a western nation. 1 or 2 international trips of less than 2 weeks each year.

Author: Immigrant to his country of residence. Applying or soon to apply for citizenship or permanent residency. Has taken multiple, lengthy international trips and also appears to have had immigration status in different countries .

Conclusion: If you are more like me than the author then international travel will not require navigation of arcane and contradictory rules.

> you take the position that [...] those people are not that bad.

I genuinely can't see where you get this except by deliberately misconstruing. I'm saying that "bad" is a nuanced position, and that we (collectively, including all the oppressed groups you're imagining) got through the last century or so in a much better position than we might have had the leaders we picked (yes, including Cheney) been more reflective of the ones ruling the rest of the world.

> If you [...] see it from the point of view of [...] humanity as a species, then of course you're right.

Well... yeah? It sounds like you're admitting to some nuance, but want it not to reflect the world we actually live in? Well... it does.

While this is an interesting data point, the main thing it tells us is that when the algorithm has no information about your preferences, that it skews racist.

This might be because, absent other information, the algorithm defaults to the "average" user's preferences.

Or it might be evidence of intentional bias in the algorithm.

The next piece of data we need is, if we take a new account, and only interact with non-Nazi accounts and content (e.g. EFF, Cory Doctorow, Human Rights Watch, Amnesty, AOC/Obama/Clinton etc), does the feed become filled with non-racist content, or is it still pushed?

But X doesn't have a lock on live information.

What people obsess over and see on X is literal propaganda

If something matters so much to your life that you can't wait the hour or so it takes to filter through normal channels, you will not need X to tell you it is happening, and knowing an hour early will not help you

Instead, X will tell you that the USA is loading nukes onto planes getting ready to fly to China (that the video shows is not nukes, not going to china, and from a marketing video several years back)

X will tell you to invest in <Scam>

X will tell you some right wing propaganda like Seattle being on fire.

People who still insist that X has good, reliable, and timely news are saying they have really bad FOMO. If you validated everything that came from X attempting to tease out the signal from the noise, that validation takes longer than just waiting for actual news to filter out. So instead, people who get their "news" from X just don't validate.

X is worse than the tabloids at the checkout line, and those tabloids have on occasion broken world news. But if you bought one every single day because of that, you would be a moron.

The thing that helped me get over that ffmpeg bump, where you go from copying stack overflow answers to actually sort of understanding what you are doing is the fairly recent include external file syntax. On the surface it is such a minor thing, but mentally it let me turn what was a confusing mess into a programing language. There are a couple ways to evoke it but the one I used was to load the whole file as an arg. Note the slash, it is important "-/filter_complex filter_file"

https://ffmpeg.org/ffmpeg-filters.html#toc-Filtergraph-synta...

"A special syntax implemented in the ffmpeg CLI tool allows loading option values from files. This is done be prepending a slash ’/’ to the option name, then the supplied value is interpreted as a path from which the actual value is loaded."

For how critical that was to getting over my ffmpeg hump, I wish it was not buried halfway through the documentation, but also, I don't know where else it would go.

And just because I am very proud of my accomplishment here is the ffmpeg side of my project, motion detection using mainly ffmpeg, there is some python glue logic to watch stdout for the events but all the tricky bits are internal to ffmpeg.

The filter(comments are added for audience understanding):

[0:v] split #split the camera feed into two parts, passthrough and motion [vis], scale= #scale the motion feed way down, less cpu and it works better w=iw/4: h=-1, format= #needed because blend did not work as expected with yuv gbrp, tmix= #temporial blur to reduce artifacts frames=2, [1:v] #the mask frame blend= #mask the motion feed all_mode=darken, tblend= #motion detect actual, the difference from the last frame all_mode=difference, boxblur= #blur the hell out of it to increase the number of motion pixels lr=20, maskfun= #mask it to black and white low=3: high=3, negate, #make the motion pixels black blackframe= #puts events on stdout when too many black pixels are found amount=1 [motion]; #motion output [vis] tpad= #delay pass through so you get the start of the event when notified start=30 [original]; #passthrough output

and the ffmpeg evocation:

ff_args = [ 'ffmpeg', '-nostats', '-an', '-i', camera_loc, #a security camera '-i', 'zone_all.png', # mask as to which parts are relavent for motion detection '-/filter_complex', 'motion_display.filter', #the filter doing all the work '-map', #sort out the outputs from the filter '[original]', '-f', 'mpegts', #I feel a little weied using mpegts but it was the best "streaming" of all the formats I tried 'udp://127.0.0.1:8888', #collect the full video from here '-map', '[motion]', '-f', 'mpegts', 'udp:127.0.0.1:8889', #collect the motion output from here, mainly for debugging ]

Geo-discounted membership fees aren’t food stamps pricing discrimination under the USDA restrictions. I’m not trying to unilaterally eliminate pricing differentials based on income, I’m just trying to find a way for a grocery store to lower the costs of food, without being exploited by wealthy people, during a food stamps crisis. I suspect the USDA can’t regulate club membership discounts, but someone else can research that.

Having just switched up to the M4 air you're not wrong. Unless you have the 8GB version and it's causing you memory pressure (which it may not be), or you really need that extra display output (I did), it's a wonder machine still 5 years later.

Also, that wedge design might be peak laptop. It's just soooo nice when lifting off a surface. I know that sounds ridiculous but the attention to detail that went into that design is next level.

Even though I'm not in the market, part of me really hopes the MacBook SE (or whatever they call it) uses the wedge design to clear chassis parts like they did with the SE iphones (although I doubt it).

If you're not actually using SNAP benefits for that particular purpose, I don't think this applies. But it won't matter, because the threat will have the desired chilling effect.

> Imagine, for example, a retailer that offers SNAP discounts only on the worst cuts of meat they otherwise have trouble selling

Oh, yes, we're just looking out for the vulnerable SNAP recipients...

Extremely costly choice would be choosing .Net or Java and never releasing at all. Creating Hack advanced whole PHP ecosystem and cost nothing in the grand scheme of things.

> Dropbox had to rewrite their sync engine in Rust, and I think they also have rewritten backend stuff in Go.

Bah, idiots, should've just waited 4 years until Go and Rust came into existence.

Geely seems like a poor choice in vehicles, I wouldn't be surprised if they end up paying enormous tariffs on it or if it ends up being impossible to work on or use here. I'm sure Geely is willing to take a loss to enter the US market but I would not be buying the vehicles for my high-tech autonomous startup from a Chinese manufacturer with no experience in the US

I've never seen a $300 one but I've seen $70 ones. I don't think they're nefarious in that sense, but these boxes are usually scams.

They come preloaded with a pirate iptv service that only works for 1-2 months then they ask you to pay something like $70/year to keep watching. There's tons of providers for these IPTV services so bundling them with the boxes is a way to make it easy to access while gaining subscriptions, you can just buy a cheap android TV box yourself, install the apk and get a cheaper IPTV provider.

Most of these boxes/providers don't last more than a couple years as authorities tend to go after them when they get too big. My dad uses them to watch portuguese TV--it would be impossible to watch certain channels outside the country otherwise--and in the past 10 years he changed provider 3-4 times.

Does the way "manifold" is used when describing subsets of the representational space of neural networks (e.g. "data lies on a low-dimensional manifold within the high-dimensional representation space") actually correspond to this formal definition, or is it just co-opting the name to mean something simpler (just an embedded sub-space)?

If it is the formal definition being used, then why? Do people actually reason about data manifolds using "atlases" and "charts" of locally euclidean parts of the manifold?

summary:

The creator argues that most dishwashers are designed to use a pre-wash dose and a main wash dose of detergent, a fundamental often ignored by single-dose pods, and presents independent ASTM testing confirming the new powder matches or exceeds the performance of a leading premium pod. The video also features a detailed demonstration using temperature logging and peanut butter to stress the importance of purging cold water from the hot water supply line before running a dishwasher, particularly in North America, to ensure the water reaches the optimal enzymatic temperature needed for effective cleaning. This is further reinforced by showing how adding pre-wash detergent dramatically improves the initial cleaning phase, especially with fats and oils.

> Right, in the same sense that existing Starlink constellation is a Death Star.

"The cluster radius is R=1 km, with the distance between next-nearest-neighbor satellites oscillating between ~100–200m, under the influence of Earth’s gravity."

This does not describe anything like Starlink. (Nor does Starlink do heavy onboard computation.)

> The example they gave uses 81 satellites…

You're right. Change the words "they were pushed" to "they chose". There's your agency.

> How about people have principles and don't change them to chase audience/money/fame, eh?

You assume that "having principles" means having your principles, and that for someone to disagree must mean they are unprincipled and simply chasing money/audience/fame. This kind of attitude comes across as incredibly arrogant and un-self-aware, and people/voters en masse want nothing to do with it.

The reality is that many millions of people are principled, and they simply have different principles.

For example, "opposing views should be aired and discussed" is a principle widely held by many millions of voters that the left has had an incredibly hard time understanding, respecting, and digesting.

What EBT money?

This is private businesses choosing to offer discounts to customers who'd otherwise be eligible for using EBT funds that are not available. In other words, a credible argument could be made that it's none of the government's damn business.

> I would like to see more of that money going to school meals, lunch and breakfast. Feed the kids directly, with another amount going to parents. Ia that feasible?

That's not the alternative here. There's no alternative here. Trump has said explicitly that he has no intention of offering ANYTHING until the Democrats agree to open up the Government again, on his terms.

I had a friend in high school who brought in the Tesla coil he made with among other things a PSU from an old computer.

I pestered that kid so hard about DC-DC voltage regulators and he did not know enough electronics to design one from first principles. I think ladder circuits was as far as he got. But I wanted step-down not step-up transformers.

15 years later when the first gen of really good LED flashlights with built-in voltage regulators popped up I owned at least one at all times.

I would say attaching things together with or from an LLM would be the analogy. Being a mechanic and being an engineer are both technical jobs which require skill, but one is design focused while the other is system focused.

I would also disagree that "professional engineer" is a meaningful distinction from engineer. I don't really think of an engineer as being something you can do casually, it's a profession.

Also re-reading my comment I should have said adjacent to mechanical engineering, generally you don't get a degree in mechanical engineering to become a mechanic.

The Radeon 8500 from 2001 was even cheaper than that, roughly 300 USD... the voodoo 3 3500 from 1999 was roughly 200 USD... if you ask me, we don't need graphics chips as intense as we have now, but the way they crank them out every year and discontinue the older models ruins most of the value of buying a GPU these days.
