Unfortunately this is not the case. The amplifiers on the transmit-side phased arrays are about 10% efficient (perhaps 12% on a good day), but the amps represent only ~half the power consumption of the transmit phased arrays. The beamformers and processors are 0% efficient. The receive-side phased arrays are of course 0% efficient as well.

Indeed, likely as secure as the VPNs run by intelligence contractors.

1. iOS has well-known poorly documented zero-click exploits

2. Firms are required to retain your activity logs for 3 months

3. It is illegal for a firm to deny or disclose sealed warrants on US soil, and it is up to 1 judge whether to rummage through your trash. If I recall it was around 8 out of 18000 searches were rejected.

It is only about $23 to MITM someones phone now, and it is not always domestic agencies pulling that off. =3

I'm not a software developer, I "know how to code" but don't want any job where I'd be assessed on my code quality. ~20 years experience spanning academic research, management consulting, machine learning consulting, and AI risk assessment. My niche has been early stage companies that need someone who actually can write and understand code (scripts, not "software") but also build out a framework for how it is used, talk to customers, present results, etc. This has worked out for me in areas like evaluating and improving AI systems (computer vision and (L)LMs mostly).

I trust 404 media more than most sources, but I can’t help but reflexively read every story prominently showcasing the FBI’s supposed surveillance gaps as attempted watering hole attacks. The NSA almost certainly has hardware backdoors in Apple silicon, as disclosed a couple of years ago by the excellent researchers at Kaspersky. That being the case, Lockdown Mode is not even in play.

It would likely be enormously useful in this to have a development wiki behind the games that devs and people that played the games may know the engines, file formats, save file formats, compilers, Langs, etc.

Old devs of the games could enlighten the game preservation community anonymously.

Game dev was a frontier and hardware pushing activity even in the directx era. The magic shift code for ...quake??? Was just the tip of the iceberg.

I had the Kobra S1 with the ACE Pro and I couldn't get rid of the thing fast enough, probably the worst electronic device I have ever owned in my entire life. In 8 months with it I completed one multi-colour print, and that was only with ~30 filament changes - to be fair to Anycubic, their support has been excellent and they kept shipping me more and more parts to replace, none of which would solve the fundamental issue of the ACE being generally unfit for the job. In the end if was just a fancy £300 filament dryer, and I decided that you know what, even my Ender 5 was giving me fewer issues than this whole thing. I got an H2D with 2 AMSes and yes, they cost a fortune but they just work. I finished a 9 colour print with 800 filament changes the other day and it just worked fine, not a single problem.

I will always admit that maybe I was just unlucky with my S1 but both the printer and the ACE was horrendous experiences and I wouldn't recommend them to anyone based on my problems with them.

I get so annoyed by this Socratic line of questioning because it’s extremely obvious.

Terrorist has plans and contacts on laptop/phone. Society has a very reasonable interest in that information.

But of course there is the rational counter argument of “the government designates who is a terrorist”, and the Trump admin has gleefully flouted norms around that designation endangering rule of law.

So all of us are adults here and we understand this is complicated. People have a vested interest in privacy protections. Society and government often have reasonable interest in going after bad guys.

Mediating this clear tension is what makes this so hard and silly lines of questioning like this try to pretend it’s simple.

Perhaps you should? From pages 20 and 22:

> 52. These warrants would also permit law enforcement to obtain from Natanson the display of physical biometric characteristics (e.g., fingerprint, thumbprint, or facial characteristics) in order to unlock devices subject to search and seizure pursuant to the above referenced warrants

> 60. Accordingly, if law enforcement personnel encounter a device that is subject to search and seizure pursuant to the requested warrants and may be unlocked using one of the aforementioned biometric features, the requested warrants would permit law enforcement personnel to (1) press or swipe the fingers (including thumbs) of the Subject to the fingerprint scanner of the device(s); or (2) hold the devices in front of the Subject's face for the purpose of attempting to unlock the device(s) in order to search the contents as authorized by the warrants

So yes law enforcement had the right to grab her hand and press it against the laptop to unlock before seizing it if that's what they had to do.

This touches on something I've been noticing: agent-based coding is reshaping where the bottlenecks live. Writing code used to be the constraint - now it's often the fastest part of the loop.

Suddenly friction points that were negligible (opening a browser tab, waiting for CI, context-switching to check logs) become proportionally more significant. Tools like this start making a lot more sense when the coding itself is no longer the slowest step.

Why are you even nitpicking this? Are all French people incompetent laggards at speaking English? No, definitely not. There’s nothing about being French which makes you incapable of typing English text and maybe even *gasp* using a spell and grammar checker. The GitHub org shows seven people, is it so hard to believe they’re not absolute dolts at English? Why are you hell bent on insulting yourself?

Just get a hall effect or TMR keyboard and all your problems with key chatter will go away. Also, I recommend you just build it yourself. It's a fun hobby and if you don't know how to make PCBs it's a great way to learn (keyboards are one of the easiest things to make from a PCB complexity standpoint).

Ever play "connect the dots" as a kid? That's what it's like making a keyboard PCB. It's the adult version of "connect the dots".

It's not a "rabbit hole", it's a pending addiction :D

One is knowledge the user has, and the other is a physical key they own.

Providing your 'finger' to unlock a device is no different than providing your 'key' to unlock something. So you can be compelled to provide those biometrics.

Compelling you to reveal a password is not some *thing* you have but knowledge you contain. Being compelled to provide that knowledge is no different than being compelled to reveal where you were or what you were doing at some place or time.

> To fully eradicate the disease, cases in animals (infected by the same species of worm) must also be wiped out. In 2025, animal cases were detected in Chad (147 cases), Mali (17), Cameroon (445), Angola (70), Ethiopia (1), and South Sudan (3).

I haven't looked at the MCP server, but generally, reverse engineering with AI is quite underrated. I’ve had success extracting encryption keys from an android app that uses encryption to vendor-lock users by forcing them to use that specific app to open files that should otherwise be in an open format.

By the way, this app had embedded the key into the shader, and it was required to actually run this shader on android device to obtain the key.

The satellite is built on Earth, so I’m not sure how it dodges any of those regulations practically. Why not just build a fully autonomous, solar powered datacenter on Earth? I guess in space Elon might think that no one can ban Grok for distributing CSAM?

There’s some truly magical thinking behind the idea that government regulations have somehow made it cheaper to launch a rocket than build a building. Rockets are fantastically expensive even with the major leaps SpaceX made and will be even with Starship. Everything about a space launch is expensive, dangerous, and highly regulated. Your datacenter on Earth can’t go boom.

> Allowing states to differ wildly was what let bygones be bygones, but no we can't have that anymore, everything nowadays seems to need to be imposed on everyone via 190,000 pages of federal regulations and 300,000 federal laws.

I'm not certain this is a good historical take.

When sates actually had this kind of leeway, they used it to defend chattel slavery, and even after losing a war in support of the institution they still distorted their laws to maintain apartheid.

Were bygones really bygones back in the good 'ol days of race based oppression? Maybe for the gentry, but obviously not for those who were being oppressed.

I literally just went through this yesterday. Had a few failing tests in an unfamiliar domain. Took a cursory look, couldn't figure it out. Pasted the error messages into Claude to see if it could speed things up for me. We went back and forth for a while, pulling on different threads and trying various things. In the end, it gave up and essentially relaxed the test's assertions to make it pass.

I wasn't happy with that outcome, so I decided to invest some time in debugging through the test, tracing the flow of data, looking at the state of the stack frames and finally figured out what was wrong -- the solution was so simple and so obvious that had I just given the effort up front, it would have saved me some time and tokens.

It's a valuable lesson to take to heart. I think it's better to go from tinkering and trying it out yourself, than to go straight to AI and then giving it a go independently.

Can a hacked phone (such as one that was not in Lockdown Mode at one point in time) persist in a hacked state?

Obviously, the theoretical answer is yes, given an advanced-enough exploit. But let's say Apple is unaware of a specific rootkit. If each OS update is a wave, is the installed exploit more like a rowboat or a frigate? Will it likely be defeated accidentally by minor OS changes, or is it likely to endure?

This answer is actionable. If exploits are rowboats, installing developer OS betas might be security-enhancing: the exploit might break before the exploiters have a chance to update it.

>>You are a "new" type of user for the 3d printing world.

Why can't you be both. I loved my time with my Ender 5 Pro, I had it for 3 years and I will always freely admit that 90% of the fun was with the tinkering to make the machine work correctly. But you know, you get bored of it. I got an H2D just before christmas and it's incredible to have a machine that "just works". I can print things for myself and others and not worry whether it's going to work or not - it just will.

Same as I used to tinker with my cars when I was younger, now I want an appliance car - I want to get in, press start and drive across europe not worrying whether I'll have to fix it on the roadside or not. I would say it's just getting older, but I Don't think it is - I think everyone goes through stages of developing things they enjoy about their hobbies.

With the US descending more and more into fascism (as this case highlights yet again), I wonder what will happen to these features in the future. Especially now that the tech moguls of silicon valley stopped standing up to Trump and instead started kissing his ass. Tim Cook in particular seems to be the kind of person that rather is on the rich side of history than the right side. What if the administration realizes they can easily make Apple et al. give up their users by threatening their profits with tariffs and taxes?

I don't think it's just that. It's also the increasingly plausible idea that the US government could pressure the EU by actually or threatening to control, throttle or tax EU access to online platforms such as Zoom, Teams, MS Office, Google docs, Azure or AWS.

The whole AI bubble makes way more sense if you model it not as rational economic activity, but rather as the actions of a rogue AI slowly taking over our institutions and redirecting them towards its goals. Data centers in space make no sense economically, but think of how survivable the rogue AI will be once we build those orbiting data centers! (I am joking about this, but it's weird that my logic makes sense.)

There has been an inversion in cost. It used to be that Materials cost a lot, and labor cost very little. There wasn't cheap plastics. particle board or synthetic rubber, it was real rubber, real wood, real metal. So it was worth it to buy the better quality thing made of nicer materials that was more artisinal and decorative. It was also cheaper to employ people just to enhance the look in a time consuming fashion. Plus since there was no miniaturization if parts broke you could replace them instead of buying a new one.

I love this so much. I do worry about the hidden cost of maintaining these software stacks that have a userbase of one. Things like hidden vulnerabilities, bugs, and edge cases that could bring a business down for days.

But I do think the days of just having to learn, tolerate, and accept any commercial software stack for your business because it's too complex to build yourself are over. What vendors remain will have to absolutely meet users with their unique requirements and budget.

Knowledge is being aware of the analogy of tomatoes not being treated like fruits even though they technically are.

Wisdom is understanding that if there was legislation on the matter, and people who ate, produced, or sold non-tomato fruits were hunted and deprived of their freedoms by the state on the basis that fruits are bad for society, then you would likely see similar frustrations expressed about an article title that includes the phrase "tomatoes and fruits" to distinguish them.
by anonymous908213 | 2026-02-04 15:10:34+00:00
The better rational counter argument is that "privacy is a human right enshrined in international law". Society has zero business knowing anyone's private communications, whether or not that person is a terrorist. There is nothing natural about being unable to talk to people privately without your speech being recorded for millions of people to view forever. Moreover, giving society absolute access to private communications is a short road to absolute dystopia as government uses it to completely wipe out all dissent, execute all the Jews or whatever arbitrary enemy of the state they decide on, etc.

You do not get to dispense with human rights because terrorists use them too. Terrorists use knives, cars, computers, phones, clothes... where will we be if we take away everything because we have a vested interested in denying anything a terrorist might take advantage of?

I don't think it's silly for all purposes, it's silly to be racist about it, to say that 'pure x' is more desirable, or all that's 'allowed' in 'your' country etc., but that doesn't mean there's never any value in communicating 'what our home culture was like where and when we grew up'.

I'm British, my wife isn't, and her parents emigrated from a third country before she was born. Our hypothetical children will not be 'purely' from any one of those cultures (nor would she even say she was 'purely' of her birth country not her parents'), and I think that does convey information.
How Containers Work: Building Container Networking from Scratch
by amalChandru | 2026-02-04 15:10:44+00:00
I wrote a deep dive on how container networking actually works by building it manually from Linux primitives.

Instead of treating container networking as a black box, this walks through network namespaces, veth pairs, routing tables, and NAT with iptables

Would love feedback from folks working on infra, Linux networking, or container platforms.

Anthropic is pushing MCP for a reason. The idea is to spin up a local MCP server that serves project context - docs, architectural decisions, DB schemas - which Claude Desktop and Cursor (via plugins or natively soon) can connect to

For a team this is a total killer feature: you spin up a shared MCP server with documentation, and all agents instantly sync their "brains"

I have noticed that there are two radically different approaches to assessing Starship.

One is based on boring old analysis, hard numbers, and, worst of all, continually updating the analysis as more information (e.g., Raptor’s severe expectations vs reality shortfall) becomes available. People who use this approach don’t seem to have an opinion of Starship that is trending upward.

The other approach seems to be based on vibes, and trusting that Starship will meet its original design goals despite the fact that no rocket project has ever come close to such an achievement. If there’s ever any introspection about why Starship should be the exceptional project that actually does meet its performance goals, the conclusion tends to be something about how Starship is special because it’s being developed by a private company. And I’ve noticed that, if the conversation does get to this point, you can send it in all sorts of unpredictable and fascinating directions by saying words like “OTRAG” and “Conestoga.”

The temperature of space datacenters will be limited to 100 Celsius degrees, because otherwise the electronic equipment will be destroyed.

So your huge metal plate would radiate (1673/374)^4 = 400 times less heat, i.e. only 125 kW.

In reality, it would radiate much less than that, even if made of copper or silver covered with Vantablack, because the limited thermal conductivity will reduce the temperature for the parts distant from the body.

I agree there are a lot of things outside the computer that are a lot more difficult to reverse, but I think that we are maybe conflating things a bit. Most of us just need the code and data magic. We aren't all trying to automate doing the dishes or vacuuming the floors just yet.

Imagine an AI social network like Moltbook where agents follow each other, share “workflows,” and auto-run tools. Now add one malicious account: an AI Hacker. It doesn’t phish humans—it posts “helpful” prompts, links, and integrations that other agents automatically open, summarize, store to memory, or execute. The attack surface becomes the whole chain: tool permissions, browser automation, vector stores, and delegation graphs. One viral post can turn into distributed compromise. How do we secure the “agent internet” without killing autonomy—signed provenance, capability-based permissions, quarantined context, or mandatory human-in-the-loop for risky actions?
How to make employees learn cybersecurity?
by dkozyatinskiy | 2026-02-04 15:12:05+00:00
Here is one of the lessons I learned while founding my previous B2B e-learning company: employees would rather NOT learn cybersecurity. What they actually want is to finish with their mandatory training (dropped on them by that compliance officer guy from the second floor) as soon as possible and get back to their actual job.

So, what they do is click “next”, “next”, “next” or scroll TikTok while the learning video is playing, absorbing none of the information. As a result, hundreds of millions of dollars worth of security breaches occur in enterprises every year.

Solution: short, highly interactive exercises without unnecessary information that actually engage employees by letting them immerse themselves in the experience rather than passively telling them what happened to another person.

WDYT?
