That may be so, but being killed isn't the only thing that pedestrians are concerned with. At best it's plain annoying to have a someone on a bike squeezing around pedestrians (remember that even a slow-moving bike is likely faste

Riding on the sidewalk is a terrible idea. The sidewalk is for pedestrians, not people weaving around on bikes. I'm massively pro-cycling, but bikes belong either in dedicated infrastructure or on the roads. Roads must not be monopoliz

It is a staggering read for sure. It's heartbreaking to imagine that little girl playing with something she thinks is a toy without knowing it is silently killing her. It's easy to think the victims were stupid for playing with a

It’s very unlikely that the name change will require any substantial technical changes within Facebook. I can’t imagine renaming configuration files, services, and so on just to reflect the parent company’s name changing. This is just makin

I don't think a semicolon is right here. Are you proposing this? "He spent a sabbatical conducting field work on Trinidad and Tobago; and in Suriname." That sounds very odd indeed — I wouldn't say the sentence with a sem

All of these are problems. None are more urgent to resolve than climate change. All the buying local in the word won’t mean anything at all when vast swathes of land are inhospitable to human life, there is unprecedented mass displacement,

Interesting! What is the overhead of this? We found that jemalloc's heap profiling had a small (perhaps 1-2%? It's been a while) CPU penalty and, depending on the complexity of the code being profiled and the sample rate, potentia

Nice write up! Using BPF to trace malloc/free is good example of the tool’s power. Unfortunately, IME, this approach doesn’t scale to very high load services. Once you’re calling malloc/free hundreds of thousands of times a second

The wording is a bit unclear (rushed, no doubt) but I expect this means the DNS servers stopped announcing themselves as possible targets for the anycasted IPs Facebook uses for its authoritative DNS [1], since they learned that the network

I agree that there's an awkward emphasis on how FB prioritizes security and privacy but nothing is deceptive here. Had the audit bug not subsequently cut off access to internal tools and remote regions it would be easy to revert. Had t

No. A network like Facebook's is vast and complicated and managed by higher-level configuration systems, not people emailing patches around. If this issue is even to do with BGP it's much more likely the root of the problem is som

Right. I’m just surprised that WhatsApp was just called out as worse than Facebook messenger. Both are owned by the same company but one of them is technically much more secure. (Yes, FB has the keys to the kingdom and can technically do wh

Haha. What possible market is there for knowing which other binaries Zoom (desktop) users run? OMG Zoom users also run Chrome, cat, and init! That'll be $10k please.

Yes, at this company there was a very neat dataset of, essentially, the output of `ps` on every host taken every N minutes. Metadata about each process also included things like binary build time, commit, open ports, UID/GID, etc. It m

There’s nothing in /proc/PID/cmdline etc that would definitely confirm an app has a GUI. The two concepts are at very different layers of the stack — to the OS the GUI is just another app on top of the kernel. Mayyyyyybe Zoom
