  • In my first year of university, we had a fun project to make us get used to physics. One of the projects required filming someone throwing a ball upwards, and then using the footage to get the maximum height the ball reached, and doing some simple calculations to get the initial velocity of the ball (if I recall correctly).

    One of the groups that chose that project was having a discussion on a problem they were facing: the ball was clearly moving upwards on one frame, but on the very next frame it was already moving downwards. You couldn’t get the exact apex from any specific frame.

    So one of the guys, bless his heart, gave a suggestion: “what if we played the (already filmed) video in slow motion… And then we filmed the video… And we put that one in slow motion as well? Maybe do that a couple of times?”

    A friend of mine was in that group and he still makes fun of that moment, to this day, over 10 years later. We were studying applied physics.



  • OK, so you have the opinion of people with flagship or even midrange phones, now here I come with my budget phone, a Redmi Note 8.

    I’ve used budget phones all my life since, well, they’re cheaper. The truth is that yes, you do notice some animation stuttering and some delayed responses, especially as the years go by and you have more apps installed (probably doing stuff in the background) and the apps you do have keep updating to be more bloated.

    This phone in particular makes it very hard to multi-task, as it’s very liberal with killing apps in the background to save RAM. This is annoying. But I’m using MI UI instead of stock android, and I’m sure I could change this.

    Honestly, I do feel like I’m being left behind and that I’m going to have to switch phones more often than if I had a more expensive model. But so far I haven’t encountered any apps I could not run (or even that I could run but only with too much stutter, making for a terrible user experience). So I’ll keep using it until I truly feel left behind, which can take a surprisingly long time. My usage time tends to rival that of people with flagship android phones and iPhones (maybe I even come out ahead)

    But you specifically asked about animation stutter. It does happen but it simply doesn’t bother me at all. It’s not constant, only happening when the phone is doing something else at the same time, and even when it does I can wait a few seconds and it’ll be fine. You also mentioned lag when opening an app, so much that you thought it didn’t register your input. It doesn’t happen to me since, while the app itself can take some time to open, the icon has feedback so I know I pressed it.

    Overall, I don’t think any of these issues are enough to bother me significantly for a good few years.

    A lot of people are replying as if OP asked a question. It’s a link to a blog post explaining why a kilobyte is 1000 and not 1024 bytes (exactly as the title says!). OP knows the answer, in fact they know it so well they wrote an extensive post about it.

    Thank you for the write up! You should re-check the spelling and grammar as some sections had some troubles. I have a sentence I need to go to the post to get, so let me edit this later!

    Edit: the second half of this sentence is a mess: “The factors don’t solely consist of twos, but ten are certainly lot of them.” Otherwise nothing jumped out at me but I would reread it just in case!



  • I was in the exact same boat as you. Except I also switched because Bitdefender, the anti-virus I used at the time, was not playing nice with Firefox.

    Earlier this year, like a few months ago, I decided to try and switch back. It was seamless. In like half an hour I had every bookmark, most passwords, and even some new extensions that have saved me a lot of work since. I recommend you try it and keep Chrome installed on the side in case you run into some problems, but I think after a few days you’ll realize you don’t need it for much.

    (in my case it’s still installed for when I inevitably remember that I forgot to transfer a random password that didn’t automatically migrate)

    Yes, a lot of people are very excited about applications that would require this material in bulk, like power transmission, and I don’t see this happening with the fabrication methods we have now. Still incredibly excited about this, though, and crossing my fingers that the results can be replicated and confirmed quickly!


  • You seem to be very knowledgeable about this field so I won’t try to change your mind, as I can tell you’re more familiar than I am. In fact, I also have my own reservations from reading the actual paper. The same authors actually have another paper in the same topic with the same material with a preprint out after this one, and I doubt someone would salami publish results as marvelous as these ones instead of just going for a single massive impact factor journal.


  • I wrote a whole thing and it sounds super condescending. I’ll leave it here but I’ll let you know I only wanted to tell people about Pre-prints and ArXiv as a whole, it was never my intention to disrespect you or any others! I even had to add this first paragraph as I felt bad about it… But here goes:

    Most papers I’ve seen are written in MS Word.

    In Physics, which I admit is what these people work in, papers written in LaTeX are more common. But still, not most of them are. No clue about Computer Science and stuff, I mostly work in Nanotechnology, Biotechnology and stuff, so mostly physics and bio stuff (…can you tell which of these fields is mine and which I’m only tangentially related to? Hahaha)

    After they are written in MS Word or paint, they are submitted for review. If they are approved (probably after a few rounds of revisions) they are submitted to the editors, which turn the paper into something that does not look written in MS Word.

    But this is arXiv. It’s a pre-print server. People submit their papers before they go through the whole peer review process. Which means that these papers can have a few very significant mistakes, or even be fraudulent or wrong. That would be my main concern.

    Of course, most of these pre-prints are not the final version of any paper - typically people submit them to pre-prints for a few reasons, while the paper is in peer review. Or often the paper has even already been accepted for publication, but they submit the version without any sort of peer review to the pre print server (I’m actually very early in my scientific career and only have one paper as first author, so this is the part I don’t remember as well. I think we submitted it to ArXiv after it was accepted for publication, but before it was published, and we sent the earliest draft we had submitted for review). These reasons are, off the top of my head:

    • The paper gets out faster, so people can see their amazing results earlier. Especially if they are worried about being the first to publish, as it’s very common for a reviewer with vested interests to block a paper from being published while they work on a very similar project. It’s not plagiarism per se, as these are loooong projects and typically the reviewer would already have a very mature project that they heavily invested in.
    • Most if not all journals are OK with the pre-print being freely available even after the article is published, even if the journal itself has a hefty fee for accessing the paper (or even for allowing your paper to be Open Access, which is typically very expensive for authors…)
    • Finally, a smaller reason: this is the paper as the authors intended, before those pesky reviewers got their hands on it. For you and I this is a negative, for authors this can be a positive. Often, reviewers will have their own interests and ask you to change your paper accordingly, most often by citing one of their papers… The peer review process is anonymous, but somehow you can always tell when this happens!

    So: don’t worry about the formatting, worry about the content! Let’s wait until this passes - or fails - peer review before accepting it or discarding it. It could be super exciting results! Or a big pile of nothing.
