Transaction rollback is probably what he meant. If that is a familiar topic to you the relation to undo should make sense and his point should be clear. If that doesn't make sense, look up ACID, Transactions, and Migrations in the context of a database.
There is a form of them which is invariant. You just have to write them correctly. Mathematics isn't as amazing as it sounds, there is a some ambiguity in how symbols are defined. Is your gradient with respect to rectilinear coordinates, or more general? Etc.
It's a Friday, quality tends to degrade during the weekend. Usually professionals reading the site tend to view and comment more during the work week while things are compiling/deploying. The weekend tends to be more hobbyist/lonely people like me.
The phrase occured only in the title and article and not in the comment they were responding too. It is possible they did not fully read the article(Most skim or read the title or title and abstract). In which case your response wasn't super helpful.
Not that I have studied this particular behavior, but evolutionary type theories like this one, tend to be found wanting after later research. For a more common example, look at the paleo diet. At a glance, the theory seems a bit bonkers if you consider natural feelings around kissing you may have had around puberty. I would imagine there might be a better explanation than some nuturing/feeding urge.
Edit: Not to be that dude, but for the downvote, explaining better how/why this feeding explanation makes sense would be nice. I thought my comment advanced the conversation somewhat.
The down votes were because you clearly didn't understand what preemption(or that this is really about it being a realtime flag) is or add much to the conversation(mentioning anything at all that might add something, like even a bad question, "I heard people using raspberry pis for embedded, would this help?"). The downvotes on the other guy are because asking for feedback on downvotes is discouraged.
To contribute, the PREEMPT_RT has been around as a set of patches(if not this specific one, then at least some version of making linux a realtime os.). If you need to know that something will run within a specified amount of time realtime matters.
EDIT: Don't use this and think it will help performance, generally it kills throughput.
Passing a "hardcore" coding test is something you can train for, and tends to not correlate well with actual software architecting and optimization knowledge.
I had the opposite experience when I met Jan Hesthaven at a GR conference. Turns out it is a German man's name and not a woman, which I found out after professing how much I love the hard 'J' versions book on spectral methods for time dependent problems.
Ah, I was hoping for some kind of thing about concurrency or reference sharing. Like look out for dangling pointers or something. My brother if you want to learn how a computer works try writing a multithreaded C++ program, the compiler will not help you much if at all. And you will make mistakes. Everyone does, even google as a whole.
So adding that is hard. I mentioned that a bit by alluding to TAILS, storage on USB is interesting since most users just yank it at some point. FSCK and making sure writes complete in nontrivial. Feature detection on boot is interesting as well. Those two points are not things you regularly want. I would prefer my modules compiled into the kernel in Linux terminology.
The article is mostly from the prospective of a B-school grad seeing SaaS's and the particular one was based on property managers which is more concrete as a topic. I didn't get much transfer of the experience to software SaaS's.
> Rust ... how computers actually work under the hood.
A curious C++17 programmer, how does Rust teach you much about "how computers work under the hood?" I thought Rust wrapped most of the ugly bits in 'unsafe' and tried to keep programmers from them?
It is a bit interesting for the future of the product that most of the comments aren't about the actual functionality that this BSD provides. The cool thing here is that you can plug it into any computer like TAILS or a few other Linux distros and use it like your own computer. Most comments seem to focus on the unconventionality of BSD's. A BSD in general is like a linux distro in that they package a kernel and userland together, usually with a package manager or a port system. The great advantage of a BSD is that usually the kernel-libc interface is designed better. For instance FreeBSD used to have a much faster writev implementation compared with Linux(from personal experience and the Advanced Unix Programming Book's test).
Edit: I tried using a \star character before BSD which apparently is italics in this editor.
Why is the graphical installer important to you? Is it to check the GPU is supported? You can usually install a DE after the initial install of the OS easily, and FreeBSD and OpenBSD at least have very nice user friendly installers.
I used to be able to run Matlab on FreeBSD(linux only since ~2016), so that made it much more desktop friendly as far as I was concerned. Currently OpenBSD can't run Wine and doesn't have any Linux compatibility layer. NetBSD had a youngin work on fixing Wine, but that hasn't been merged in to a release.
Kinda my point. If he has this tool it is a potential game changer. If not, why publicize a dumb tool that scavenges my bank account and posts that publicly? Where would I derive value from that? I basically think the product is shit, and degrading and worthless at best, but am trying to provide direction.
So, I am ideal consumer. High value. I would pay. Why would I use your service? I own ~$10k dollars USD. I have >2Million <8Billion in stock. How will you present me?
So I am willing mainly as a form of social currency, a lot of women ask about money early on. I own a lot of unusual investments and some more conventional ones. I exist on my more conventional interests, and I would be silly to say no woman has wanted to know all I own.
People have at least once though the citation escapes me, it was 2006ish. And it could be found in agreement with observation. Not that I believe in it.
