Confusing title, both the original and the one here on HN.

Three french supermarket chains had their refrigeration systems hacked.

Separately, a super market chain serving Belgium and the Netherlands shut down a large chunk of their IT systems due to a "cybersecurity incident", primarily affecting distribution centers and grocery delivery services. But the supermarkets are currently open, and do not have refrigeration issues.

Suspicious timing and these incident could well be related, but that has not been reported so far.

It could well be one ransomware attack on Ahold Delhaize, and an unrelated attack on a refrigeration supplier. Note that a similar refrigeration attack happened happened to a number of US military installations a few weeks ago.

The ones mentioned in this thread all use Kiwix for off-line wikipedia, OSM for maps, Khan for educational videos. It looks like internet-in-a-box is aimed at working well on low-powered devices, whereas nomad expects beefy hardware and includes local AI. Not sure how WROLPi differs from internet-in-a-box.

Maybe it's like linux distros: all based on the same software, but optimized for different use-cases or preferences.

The full report can be found here: https://services.google.com/fh/files/misc/2025_state_of_ai_a...

That 17% increase is in self-reported effectiveness. The software delivery throughput only went up 3%, at a cost of that 9% extra instability. So you can build 3% faster with 9% more bugs, if I'm reading those numbers right.

I've been annoyed with Google search quality lately and was wondering how the others fared on this specific issue. Turns out, mostly not much better.

Bing, DuckDuckGo, Qwant, Ecosia, Brave all had the github repo and nanoclaw.net (the fake homepage) in the first or second place. Marginalia had fascinating results about biology but only tangentially related Nanoclaw results, not the github repo or either the fake or real homepage.

Mojeek was the exception, sort of. It had some random news sites up top, but the github repo in 2nd place and nanoclaw.dev (the real homepage) in the 4th place. The fake nanoclaw.net did not show.

Kagi is the only one I couldn't try because apparently I used up my free credits a year back. Can anyone see how they compare?

Agree with all of that, especially modern supply chain risk (imho the more important reason to opt for VM isolation rather than containerization). But the original article specifically talks Vagrant as an isolation solution, and describes it as not protecting against VM escape, but also that guest-to-host 0day is rare.

Hence pointing out that VM escape is a lot easier than that if your VM management tool syncs folders the way that Vagrant does by default.

It's the default behaviour for Vagrant. You put a Vagrantfile in your repo, run `vagrant up` and it creates a VM with the repo folder shared r+w to `/vagrant` in the VM.

> What you’re NOT protecting against:

> a malicious AI trying to escape the VM (VM escape vulnerabilities exist, but they’re rare and require deliberate exploitation)

No VM escape vulns necessary. A malicious AI could just add arbitrary code to your Vagrantfile and get host access the first time you run a vagrant command.

If you're only worried about mistakes, Claude could decide to fix/improve something by adding a commit hook. If that contains a mistake, the mistake gets executed on your host the first time you git commit/push.

(Yes, it's unpleasantly difficult to truly isolate dev environments without inconveniencing yourself.)

  Location: The Netherlands. I'm flexible with working hours, I usually work with clients from either Western Europe or the USA.
  Remote: Yes
  Willing to relocate: No, but willing to travel/visit
  Technologies: especially Ruby (including Ruby on Rails, Sinatra, and standalone applications), PostgreSQL, Ansible, Linux. Lots of others at the end of my comment.

I do dev/devops/security, usually for startups or scale-ups or other small orgs with limited resources, and I've been doing that for 15+ years. So, if you:

* Have a slow web application that’s often down?

* Want to improve security and don’t know where to start?

* Have a legacy system that needs to be replaced?

* Are considering an acquisition but not sure about the technical side?

I can help with that. For example, in the past I have:

* Massively improved performance and reliability for a data visualization platform.

* Led a large effort to improve security for a cybersecurity SaaS.

* Built a micropayments system for a prominent media startup.

* Rebuilt an aging e-learning platform from scratch for a GDPR compliance SaaS.

* Conducted technical due diligence for acquisitions.

For more information: https://www.luitjes.it

Other tech I've worked with: Elixir, C#, Java (Spring/Hibernate), JavaScript, HTML/CSS/XSLT/XPATH/XSLFO, Elasticsearch, MongoDB, MySQL, Redis, Solr/Lucene, Graphite, Kibana, Grafana, Logstash, Icinga, Jenkins, Varnish, HAProxy, Pound, Nginx, Apache, Passenger, Vagrant, Docker, DCOS, Kubernetes, SSH, OpenVPN, TCP/IP, tcpdump/strace/lsof/etc, AWS (EC2, ELB/ALB, S3, CloudFront, Lambda, Batch, VPC, etc.

This.

If you were writing a script to mass-scan the web for vulnerabilities, you would want to collect as many http endpoints as possible. JS files, regardless of whether they're commented out or not, are a great way to find endpoints in modern web applications.

If you were writing a scraper to collect source code to train LLMs on, I doubt you would care as much about a commented-out JS file. I'm not sure you'd even want to train on random low-quality JS served by websites. Anyone familiar with LLM training data collection who can comment on this?

GrapheneOS is basically the Android equivalent of iOS Lockdown mode. Considering how the threat landscape has changed, it would be nice if Google offered this itself. Or became a long-term sponsor of GrapheneOS, seeing how great a job they've been doing.
