Sure, on paper, that will always be possible - just not in the age of signed kernel images that are cryptographically verified by your immutable bootloader.

FWIW (and iirc), with programs using recent-ish glibc, you will never see a call to open() in the wild unless the program takes special care to bypass the implicit libc wrapper. glibc will transparently convert these calls to openat() under

You can stop output on a terminal (emulator) by exercising flow control. If you get overwhelmed by `tail` (or a similar tool's) output, hit ^S. If you are ready to resume, strike ^Q.

Given that the actual reviewers of scientific works aren't paid, I'd say that the publishers like Springer and Elsevier came up with a pretty good system (first and foremost good for themselves, though) to do just that. ;)

Could it? Yes. Will it? Maybe. Would I count on it in all cases? No. Also, I find it preposterous to rely on a second automated system to cancel out the mistakes the first one made.

That's just like, your opinion, man. The tens of thousands of users that migrated to other networks feel differently about the matter.

I have several networking devices around the country with OpenWrt on them (for example, at my mom's house). They serve different needs, with different selections of packages installed, and are not of the same hardware, so keeping them

Just a few weeks ago, I fixed a problem in an internal tool (that still also runs on an ancient Solaris 10 box) by switching from `awk` to `gawk`, since the former would briefly whine on stderr and quit whenever a line in its input would co

While I find this post and the ideas presented very interesting on the technical level, work in that direction ("remote attestation", making devices "tamper-proof") tends to give me a dystopian vibe - foreshadowing a wor

I don't see that (some communities opting for libera.chat, some for OFTC) as a problem, though. Recent events show that some amount of IRC network diversity can only be a good thing.

Template rendering performance has always been one of my gripes with ansible. Have you ever taken up the challenge to debug/profile it, and get to the bottom of that seemingly obscene slowness? (It's one of those things I always p

This right here. For programs that do not require access to an X11 display, you could also work around the problem of not really trusting the code to not do anything that isn't in your best interest by using `sudo` (or `su` or `setpriv

But you don't get to have that! You get the "insane" syntax oh bash, encapsulated in a ridiculously verbose and frankly quite unintuitive JavaScript contraption that seems to provide little, if any, benefit. Also, Shell scrip

This embodies so much of what is wrong with some JavaScript programmers' (that I've known personally) mindset that I find it hard to distinguish from satire...

$oldjob had that too, and it worked really well for most people - tech and business alike. I like IRC because it makes you focus on what really matters instead of some sort of seamless Giphy or Wikipedia "rich"-content integration

I don't see how appending --cpus 2 --memory 500mb to the argument vector liberates these options' definer from "understanding [...] the subsystems that power it", and reflect on their potential impact. And I&#x2

Linux disagrees; try strings /proc/*/environ to see for yourself. On Solaris/SunOS, you could use `pargs -e $PID`. And so on. Having separate UIDs to run your processes A and B under shields either one from peek

I've not seen such a design yet, but if you don't need that kind of bandwidth for your WAN link (and I guess you won't - but tell me otherwise, and I will certainly be a wee bit jealous ;)), you can always just attach a switc

Personally, I would never buy SoHo networking hardware that does not have decent OpenWrt support - the platform is supremely flexible, hackable, and secure. If you're in the market for a new device, look at https://openwrt.o
