The executed bit is an attribute that the FS stores about the file, and isn't technically part of the file itself. Strip all the execute attributes out of your *nix system and see what happens.

This article is just as useless as asking "why are all your file formats different and confusing?" I mean, it's just binary data, right? Why can't they just write all their ones and zeros the same way?

I suppose with unified memory there's no real difference between the kernel and userspace; it's just different security zones. The MMU era used separate memory spaces to enforce security, but it's probably safer in the log ru

One use case is to mount 360 cams on a bunch of motorcycles (fleet) and do a google streetview equivalent. You build a city level streetview pretty quickly. I think at that point you'd just need to do 1 pc every 200 readers and pull th

With any database architecture the goal is to ensure that nothing hits your database if you can help it. We served 13 billion requests last year, according to fastly, and burned 3.84PB of data. Each one of those requests will generate a bun

The true hero in AWS is its authentication and accounting infrastructure. Most people don't even think about it. But authenticating trillions of operations per second is why AWS works. And the accounting and billing. Anyone that does a

Well, google cloud has destroyed entire accounts, but I suppose that's not a storage failure per se.

I'd love to see the data they're getting. This might be the last time that anyone will be able to cross-reference financial data across the federal government.

Nobody should use recursion in production code, period. And no, it's not like malloc. If you don't understand why then you definitely shouldn't be putting recursive calls in your codebase.

People have been trying to shoehorn the Internet into the OSI model for decades. It's like the OSI supporters have waged a campaign to be relevant...and won. It's a nice model, but once it gets above the phy layer it becomes sort

Caching is a funny thing. Just like anything you need to understand if and why you need it. And one other thing is you should be able to fall back if your cache is invalidated. In our case we keep a bunch of metadata in redis that’s relativ

It's essentially portfolio management. You win some, you lose some. And you work at a phone company, and phone companies have interesting problems. I'm sure at some point everyone there felt somewhat obligated to do something to c

When the Internet was built there was an expectation of anonymity. But anonymity and privacy are not quite the same. And in fact, the Internet is not anonymous or private, as there are multiple ways to track and surveil members of the gener

They did it for efficiency. The observation was that the human voice doesn't use most of the audio spectrum, so they optimized everything for voice. A reasonable decision at the time.

I was hoping it was something about reducing process latency by using some obscure IOCTL call or switching the scheduler.

I suppose the latency was reduced because the process wasn't being terminated by the kernel anymore. Really, the title should say "PR_SET_PDEATHSIG doesn't mean what you think it means." The man page for PR_SET_PDEATHSIG
