Another big thing that doesn’t get covered by big O analysis is the potential for parallelization and multi threading, because the difference created by multi threading only amounts to one of those dropped coefficients.

And yet, especially for the workloads being run on a server with 32-128 cores, being able to run algorithms in parallel will make a huge difference to performance.

It may not have been dark out but it was still pretty cool seeing shadows get messed up and seeing the sun get covered through eclipse glasses.

Definitely hoping to travel to one of the total eclipses in the later 20s/30s tho

I don’t actually think eclipse is completely terrible (just saw the opportunity for a meme). My main problem with it is that unlike intelliJ, the UI buttons don’t scale with the font size, making it pretty unusable on my HiDPI laptop.

For now I’ll just stick with IntelliJ/idea IDEs (I have access to an education license for ultimate) and then if/when Idea ruins it I’ll probably just try to integrate my Java workflow into either VS Code or an nvim setup

You’ve fallen into my trap card, I really just wanted everyone else’s eclipse photos here

For anyone else confused: in this case NLP stands for “Network location provider,” not “natural language processing”

Java is reasonably fast though, as the JRE is pretty well optimized at this point. Languages closer to being fully interpreted like JS and Python (technically both python and JS still get compiled to a lower target and then interpreted) are still noticeably slower.

Edit: there’s also the fact that JS/TS runs on a single thread, so it’s inherently limited for applications intended to be scaled up.

As a dev who works on both Java and C# code, modern Java (17+) and C# feel almost exactly the same (not sure if Java has extension methods though).

Bonus points for using Kotlin instead tho. I dislike both Java and C# just because they both allow any object to be null and that’s usually a headache whenever a null exception shows up.

The only thing I like better about C# is the Fixture library for testing. I haven’t found any mature libraries like it for Java yet.

I think we’re on the same page? If an attacker wanted a keylogger they wouldn’t even need to go as far as a screen, there are plenty of other ways (like a 3rd party keyboard app) that would work just as well, if not better, on an iPhone.

Hell, while we’re at it, using a phishing email to get you to enter a password in a fake site or using social engineering to reset your passwords is way more effective than reverse engineering and modding a camera/screen.

There’s no reason why Apple should get to keep exclusive rights on repairs just to profit more on parts. 3rd party screens, cameras, face id modules, etc. aren’t going to suddenly make your phone less secure.

TS and JS are completely single threaded unless you have multiple instances of node running at the same time.

You can have both though. Just add some random menu in the settings that turns bright red when using a non-certified component so security can be easily verified, but don’t needlessly lock people out and charge $500 to fix a $10-50 module on a $1000 phone

Edit: Adding on to this, Ifixit isn’t outlawing verification, the above example of whatever red warning is a clear way they could keep it.

If you think keyloggers require software running on your physical keyboards you’re in for a rude awakening.

Keyloggers are almost always at a pure software level and are conceptually simple to make. So simple that in fact, it’s the same thing as running a regular application with background shortcuts. The only thing that is different is that regular apps aren’t saving/recording anything, they’re just listening for you to press cmd+whatever.

It takes maybe ~10-15 minutes to make a keylogger in Python that could run on any computer, mac, windows, or Linux. Maybe a little longer if you wanted to use a compiled language and properly hide it.

Sorry to burst your bubble.

No, you can’t, because that isn’t a good analogy. Those two situations are not at all the same, but I’ll humor you.

The analogy you’re making is like saying only the company who makes doors is allowed to change the lock on your door, and they’re allowed to just stop offering the lock-changing service whenever they want. They also conveniently put a mechanism in so that whenever a third-party locksmith comes, your door falls apart. Your only option is to buy a new door, doorknob, frame, and hinge because your lock is worn out.

I’m not arguing that it’s the same as a conventional wire, but it is definitely still electricity. Communicating a signal by difference in ionic charge is, by definition, an electric signal, even if it’s the movement of ions in a pump instead of electrons across a solid wire.

Ion potentials are electricity… That’s the same thing as a voltage measurement: a difference in ion charge between two areas. Open the gate and the charge diffuses. That’s a wire.

Edit: poor phrasing with use of the word “wire”, I meant in a sense that it’s moving electricity, not that it’s a conventional solid wire with flowing electrons.

As a current computer science college student who was a TA for 2 semesters, can confirm… It’s wild out here
