Safeclaw can do most o f what openclaw can do. Emails, telegram, summarize the news, documents, images, OCR, check out sites and crawl links and report back to you. No AI, no apis, it all actually stays on your machine.

It has no language model, it uses vader, sumy, yolo, spacy and a bunch of other ML techniques to give you the experience of openclaw in a safer way. Let me know what you think.

Most business leaders track content metrics that look impressive but mean nothing to the bottom line. Page views don't pay salaries. Social shares don't close deals. If you can't connect your content to revenue, you can't justify your budget. This guide shows you exactly how to measure content performance using metrics that operations leaders and CFOs actually care about—from engagement rates that predict conversion to ROI calculations that prove business impact. No fluff, no vanity metrics, just the data-driven approach that transforms content from a cost center into a measurable revenue driver.

I am no fan of Musk the man. SpaceX is a strong company and Falcon is a solid vehicle. There is not a lot of competition, and NASA trying to in-source design and supply and construction of a new, reusable LEO rocket would be a complete nightmare.

I root for a competitive rocket market, but SpaceX is at the moment critical.

The proof is that they are continuing to launch more mass into orbit than any other entity on the planet - while holding share liquidity events for their employees multiple times a year where they buy back shares. Proof is that they charge a lower cost to orbit than any of their competitors and has done so for years now.

Their revenue from Starlink is slated to be bigger than the entire NASA budget this year.

Perhaps the objection started out with something fundamentally irrational or opinion-based, and someone was ordered to "reverse-engineer" an objection out of that which wasn't trivially refutable - e.g. "the noise from the turbines will keep our submarine sonar from working" or "reports say that human smugglers are hiding aboard the windmills" or whatever.

Probably not. The ISS got a solar array upgrade after its initial launch:

https://www.spectrolab.com/company.html

Twenty-five years after the ISS began operations in low Earth orbit, a new generation of advanced solar cells from Spectrolab, twice as efficient as their predecessors, are supplementing the existing arrays to allow the ISS to continue to operate to 2030 and beyond. Eight new arrays, known as iROSAs (ISS Roll-Out Solar Arrays) are being installed on the ISS in orbit.

The new arrays use multi-junction compound semiconductor solar cells from Spectrolab. These cells cost something like 500 times as much per watt as modern silicon solar cells, and they only produce about 50% more power per unit area. On top of that, the materials that Spectrolab cells are made of are inherently rare. Anyone talking about scaling solar to terawatts has to rely on silicon or maybe perovskite materials (but those are still experimental).

The people eligible for passports are not the same group of people eligible for voter id since there are a few jurisdictions where non-citizens can vote in certain elections. Voting is also a responsibility of the states (even at the federal level), so there isn't really such thing as a federal voter id since each state has different eligibility requirements for voters that don't necessarily align with passport eligibility. Additionally, passport cards aren't interchangeable with passports in most countries.

Also, every four years? Elections happen more or less constantly in this country at some level or another. Federal elections are every two years, BTW, and that's if we ignore special elections for federal candidates. You should learn more about the system you live in.

The current round of stop-and-search would be enabled by making passport cards or some form of universal id. The current legal reality is that you do not need to prove your citizenship on demand if you are already in the US as a citizen. The burden of proof - rightly in my opinion - lies with the government to prove that you are not a citizen. Frankly, I'm quite uncomfortable with "paper's please" entering the US law enforcement repertoire. The fourth amendment was pretty clear about this.

With the CBP using mere presence validated by facial id only at legally protected protests as reason to withdraw Global Entry enrollment, it seems more and more clear that we do not need to be giving more power to the people who do not understand the 4th and first amendments. Removing people from Global Entry for protected first speech is, afaict, directly in violation of the first amendment even if Global Entry is a "privilege"

There are two types of engineers/companies:

1. Clueless: AI is the future, grant it access to everything and let it do everything, from management to execution.
These engineers will be unemployed and companies go bankrupt. This is the majority of the market right now, look what is happening to them from companies to the products themselves.

2. Smart: AI is a tool to improve my work so I can spend less time doing the boring stuff and more time learning and doing cool stuff.
This is the minority and the only companies thriving right now.

Atlassian had on premise option already.

All instances I remember seeing were neglected, not updated running on lowest amount of resources. Everyone in company nagging how slo it is but no one wanted to share budget to improve it.

So for me that experiment „it will be better and cheaper building our own JIRA” was already done. It is going to be cost center that no one will want to throw money at.

When a company is operating at a scale where you are making orders of magnitude more orbital launches than NASA, operating a constellations of 10,000+ satellites, providing internet access to 10s of millions of people and 1 army, has raised $10s of billions in private markets at valuations in the $100s of billions, then the burden of proof is on you claiming the opposite.
by luke5441 | 2026-02-02 23:38:57+00:00
I wouldn't be too sure. Depends on NASAs mission profiles and a lot of factors. Falcon heavy can bring 26.7t to GTO in expendable mode and only 8t in reusable mode. Reusable cost of Falcon is US$97 million vs US$150 million expendable.

How much does it cost to develop and maintain the reusability? Is it worth the trade-offs in lower tons to orbit due to more weight? Is it worth it adjusting the payload into smaller units, including developing things like refueling in LEO?

Idk, I'm not on the inside doing those calculations...

Tesla cars made in Shanghai are sold in Europe and other places. That is helping them be competitive and they haven't had much price pressure until recently. Just because the Chinese have their own internal competition and deflation which drove their prices down aggressively doesn't mean it was a bad idea to build there. Also the idea the Chinese couldn't figure it out without an American company coming there first to show them is pretty silly.

Tesla Shanghai opened in 2019

BYD made their first hybrid in 2008 and they were a battery company since the 90s

Sadly this seems correct. When Trump was re-elected Elon Musk pushed for Jared Isaacman to be appointed as NASA administrator. When the pick went another way, it led to some real friction between Musk and Trump. Now, with Isaacman finally at the helm of NASA, it looks like Musk’s influence over the agency has come full circle.

It's hilarious how transparent a money grab this entire thing is.

"You need to show a Real ID for security, otherwise how do we know you won't hijack the plane?"

"Well I don't have a Real ID."

"Ok then, give us $45 and you can go through."

So it was never about security at all then, was it?

And don't get me started with all the paid express security lanes. Because of course only poor people can weaponize shoes and laptops.

When does the market realize this is all just a shell game and the emperor really has no clothes?

We saw this on a much smalelr scale a decade ago when one of Elon's companies (Tesla) acquired a second one of Elon's companies (SolarCity) because it was broke and owed a ton of money to a third one of Elon's companies (SpaceX).

Elon was forced to go through with his impulsive Twitter acquisition by a Delaware court, an acquisition that was not only secured by a bunch of Tesla stock but also a bunch of Qatari and Saudi royal money. He then mismanaged Twitter so badly Fidelity wrote down its value by at least 80% [1].

So what did Elon do? Raised even more questionable foreign money into xAI, diverted GPUs intended for another of his companies (Tesla) into Twitter and then "merged" Twitter into xAI, effectively using other people's money to bail him out from an inevitable margin call on his Tesla stock.

Interestingly, Twitter was reportedly valued at $33 billion in this deal [2], significantly more than the less than $10 billion Fidelity valued Twitter at. Weird, huh? With a competent government, this would be securities fraud that would have you spend the rest of your life in jail. And even with all that, $11 billion was lost on the deal.

So here we are and it's time for the shell game to be played again. Now it's SpaceX's turn to bail out the xAI investors.

And what is the argument for all this? AI data centers in space. Words cannot describe how little sense this makes. Launch costs (even if the Starship launch costs get to their rosy projections), cooling in space, cosmic rays (and the resulting errors) and maintenance. Servers constantly need parts replaced. You can just deorbit the satellite instead but that seems like an expensive way of dealing with a bad SSD or RAM chip.

A former NASA engineer with a PhD in space electronics who later worked at Google for 10 years wrote an article about why datacenters in space are very technically challenging:

https://taranis.ie/datacenters-in-space-are-a-terrible-horri...

I don't have any specialized knowledge of the physics but I saw an article suggesting the real reason for the push to build them in space is to hedge against political pushback preventing construction on Earth.

I can't find the original article but here is one about datacenter pushback:

https://www.bloomberg.com/opinion/articles/2025-08-20/ai-and...

But even if political pushback on Earth is the real reason, it still seems datacenters in space are extremely technically challenging/impossible to build.

I think regardless of implementation, if the added complexity reduces reliability and introduces forced failure modes it's reasonable for people to avoid these systems altogether. For example, EGRs causing fouling or DEF engine throttling.

This may be true for our group, but I know numerous blue collar workers at the poverty line struggling due to these systems. Corporations / manufacturers have no incentive to make these systems more accessible. Even if they did, more complex -> more expensive to repair.

What olds? The shutdown here was ostensibly for national security reasons.

> Let them cancel the wind farms if that means a free hand to develop solar.

That's not actually a bargain anyone has the power to agree to in a binding way. The people protesting the appearance of wind farms are on the coasts, the people protesting solar are in the country's interior. There's no "deal" you can make to get the latter instead of the former. Just build all the power generation and then we'll have cheaper electricity and a more resilient grid.

The CAA allows parties with no standing to sue, to magically have standing to sue, and then have their victims pay lawyers fees (or otherwise go to jail[0]). So there's no need for the EPA to get involved. You can just be sued by, say " Utah Physicians for a Healthy Environment" and end up paying unlimited lawyers fees because some guy 300 miles away says you dropped a particle of carbon on them.

That's a bit of an understatement. Every single LLM is 100% vulnerable by design. There is no way to close the hole. Simple mitigations like "allow lists" can be trivially worked around, either by prompt injection, or by the AI just deciding to work around it itself (reward hacking). The only solution is to segregate the LLM from all external input, and prevent it from making outbound network calls. And though MCPs and jails are the beginning of a mitigation for it, it gets worse: the AI can write obfuscated backdoors and slip them into your vibe-coded apps, either as code, or instructions to be executed by LLM later.

It's a machine designed to fight all your attempts to make it secure.

> Cars, and in particular, parking, kills cities. Parking is sponge that sucks all the life out of places.

Yes, and. If you start charging for parking to try to fight against this without also improving public transportation, it just kills cities faster. I avoid going into downtown cores where I will pay $25-$40 to park for an hour or two to eat at a restaurant, which means those restaurants can only support their businesses off captive people during the work day, which means that moving to remote work widely across society devastated downtown cores in a way you would not have expected. All because I can get downtown in 15 minutes from my house in my car but it takes 3 hours and 20 minutes by bus and there is no other public transport in the 7th largest city in the US by population.

Cars are the enemy, sort of, but the biggest enemy is the complete lack of any reasonable public transport in almost every major US city, which needs to exist to fairly ratchet up on parking.

Surely it varies a lot and everyone is in an industry bubble to some extent, but from my experience in some non-tech industries (healthcare, manufacturing), Linux workstations were nonexistent and working with the Linux servers was more a sign of an ops role. People who wrote code for a living didn't touch them directly. Last StackOverflow survey [1] puts it at something like 50% use Windows at work, 30% Mac, 20-40% Linux (breakdown of WSL and Ubuntu as categories seems confusing, maybe the raw data is better).

Show HN: Nono – Kernel-enforced sandboxing for AI agents
by decodebytes | 2026-02-02 23:42:40+00:00
The problem: AI agents execute code on your machine. Prompt injections, hallucinations, or compromised tools can read ~/.ssh, exfiltrate credentials, or worse. Application-level sandboxes can be bypassed by the code they're sandboxing.

I have been around security for a long old time now (i started something called sigstore a few years back) and have seen this pattern so many times before.

nono uses OS-level isolation that userspace can't escape:

Linux: Landlock LSM (kernel 5.13+) macOS: Seatbelt (sandbox_init) After sandbox + exec(), there's no syscall to expand permissions. The kernel says no.

What it does:

nono run --profile openclaw -- openclaw gatewa
nono run --allow . --net-block -- npm install
nono run --secrets api_key -- ./my-agent

Filesystem: read/write/allow per directory or file Network: block entirely (per-host filtering planned) Secrets: loads from macOS Keychain / Linux Secret Service, injects as env vars, zeroizes after exec

Technical details:

Written in Rust. ~2k LOC. Uses the landlock crate on Linux, raw FFI to sandbox_init() on macOS. Secrets via keyring crate. All paths canonicalized at grant time to prevent symlink escapes.

Landlock ABI v4+ gives us TCP port filtering. Older kernels fall back to full network allow/deny. macOS Seatbelt profiles are generated dynamically as Scheme-like DSL strings.

Limitations:

macOS: Currently allows all reads to make executables work. Tightening in next release. Linux: Landlock doesn't cover everything (no UDP filtering until recent kernels, no syscall filtering - that's seccomp territory) No Windows support (yet?)

GitHub: https://github.com/lukehinds/nono
Docs: https://docs.nono.dev
Site: https://noto.sh

Apache 2.0. Would love feedback on the security model, especially from folks who've worked with Landlock or Seatbelt. Having said that, the code needs a good tidy and I am not exactly proud of it, so go easy on me!

the Venezuelan oil leases you are talking about was 1990s, not 1970s.

for Venezuelan oil leases to be comparable to wind farms you'd have to have the Venezuelan govt say "we are taking the leases away because we don't want any more offshore oil production", rather than "we are taking these leases away because you are rich and we want to pump the oil ourselves"

the cancelled Venezuelan oil leases were a taking, but that word is less useful in the case of wind farms. I would imagine firms with wind farm contracts would be made whole (i.e. get back lost investment, but not get back potential profit) but it's not a case of the wind farms being given to somebody else or those areas being put to some other use.

if you are "environmental" you might think it's a great loss not to pursue the wind approach, or that it's a great idea to shut down offshore drilling, but that's political not property ownership/taking.

AnkiHub people seem kind of slimy in my experience (at least their leader, "The AnKing"). I hope they figure out a good leadership situation, and make stronger commitments to openness.

Anki is in a very solid position to be forked if anything happens, so even if this is bad news I have faith in the larger community.

> tone: I don't really understand orbital mechanics, but I do understand geopolitics a bit.

Thanks for the clarification, I guess that explains this (from you):

> Think about how hard it would be to practically take out Starlink.

and this:

> My entire point is that constellations in GEO

which you've now corrected.

Moving on:

> My entire point is that constellations in LEO take hundreds of Falcon 9's worth of mass to orbit and delta-v to destroy them, as in-orbit grenades which approach gently. This IS REALLY HARD

So let's not do that .. how hard is it to render the entire LEO zone a shit show with contra wise clouds of frag that cause cascading failures?

Forget the geopolitics of China et al. .. LEO launch capabilities are spreading about the globe, it's not just major world powers that pose a threat here.
