This is a fantastic in-depth look at debugging a complex problem, and the fact that the rest of the system remained stable is a testament to the quality of the engineering work that the Oxide team put into this. I'm personally quite in

Do be aware, though, that this is just a way to make builds fail fast if you have an older compiler. It doesn't put the compiler in a mode that makes it reject features introduced after that version. If projects want to maintain an MSR

Disclaimer: I'm not an expert in Cilium! Only recently got into reading about it because of Jessie Frazelle's tweet about it. Still planning on deploying it into my small homelab. It's my understanding that Cilium chose to do

This depends on the CNI plugin you're using. In particular, Cilium implements the entire firewall in eBPF.

I highly recommend you do a search for Firesheep - the tool that really started the push for HTTPS everywhere. You're right that a malicious network operator would be in a position to request users install root certs, but the problems

Another fascinating look into text on computer screens is this article: https://gankra.github.io/blah/text-hates-you/ . Just goes to show that text rendering is actually absurdly complex, unless you drastically res

> You can for the most part just convert the LLVM bitcode that the Rust compiler would output to the equivalent C snippet. Sounds like a good argument to resurrect the LLVM C backend. As it stands, the Rust core team has no desire to imp

Honestly, even with minor versions, I'd prefer to use something like dependabot, or for a bot to open a pull request bumping versions. Tons of authors mess up semver in subtle ways, it's just much easier to avoid problems if you j

For one, respected community member pcwalton has argued against compiling to C, citing the difficulty in producing performant, memory-safe output. For another, from personal experience, I can comment that compiling to C in such a way that d

What's more, the Gentoo maintainer that filed the issue lists a number of platforms that CPython itself doesn't even support.

Indeed, a commenter demonstrates that resolving the issue on Alpine Linux was as simple as adding an `apk add rustc cargo` to their Dockerfile.

Uhh, they do embrace bigotry. The official Gab twitter feed has posted openly bigoted comments, not just quoted from their site.

That's unfortunate, since an IOMMU is an excellent solution to this kind of problem, especially when one considers all the potential Linux USB stack vulnerabilities that can be exploited if you assume the modem is untrustworthy.

by moosingin3space 7y ago
You can use an IOMMU to isolate DMA to a separate security domain. This is how Qubes OS works.

Fellow UMich grad here. Shapiro library (formal name for UgLi) was always a great place to study because you had plenty of noise isolation from other people, especially the upper floors. On North Campus, CS majors had two major study spaces

I'm excited about this project too, but how does it "reduce the influence that Google and Facebook have on the Web"? It seems pretty orthogonal if you ask me.

All of these sources show memory safety problems getting worse or staying equally prevalent, which directly contradicts the parent's claim that memory safety is "much less of an issue than it used to be".

> Memory safety is much less of an issue than it used to be. This is demonstrably false: https://twitter.com/LazyFishBarrel/status/112900096574140416... Additionally, new "safe" C++ APIs aren't:

That can be made a runtime concern - if you use Kata Containers as a runtime for Docker, it'll use a VM instead of kernel namespaces.

This is an excellent analogy and I can't understand why it's being downvoted. Software is only as useful as its surroundings find it useful.

To those of us who actually contribute to the Linux desktop ecosystem, this isn't news.

Signal can use WebSockets, as their non-FCM version (downloaded from their website) does. I've come to agree with Daniel Micay about the best way to separate apps from Google services: https://www.reddit.com/r/Grap

The UMich network isn't "improperly configured". NAT-less networks have been around since the beginning of the Internet, and IPv6 networks don't use NAT (unless they're accessing IPv4-only targets, but that's C

I'm no Linus Torvalds fan, but his rant (and follow-up) on PAE explains why this is actually a terrible idea: 1) https://www.realworldtech.com/forum/?threadid=76912&curposti... 2) https://www.realwo

What if your DHCP doesn't give you a private IP address? When I was at the University of Michigan, my personal laptop always received a public IP address. Or if I'm in a pure-IPv6 setup, using prefix delegation/SLAAC? This pr
