Don't bother with the links, the comments are more informative. In some of the comments people explain why it's Intel's fault and not Apple, in some comments people explain processor speeds. A lot of it is about the keyboard that they changed, but that is not related to this. My point was more that I think Apple should put the amount of effort into their laptops that they did in 2009, whether or not they do is subjective until we see their new processors.
While I don't know much about phones and suppose you are correct there, I have been disappointed with the hardware that they pushed to their macs the last 5 or so years. For instance, why did they ship newer macs without upgrading to the newest Intel chips?
I guess you can solve anything if you do it yourself, but that was perplexing for me that they would do that. I am not an expert on this, but this happened some time between 2016–2018.
Edit: I stuck with my upgraded 2013 model and even today it's fast and good for the job. Even my 2009 mac is still running. So I am not saying they can't pull it off, I am just wondering whether they give enough attention to their non-iPhone products.
To paraphrase my supervisor "Mathematicians don't read, we write."
Not to be taken literally, of course. But there is some truth in that. If you are an engineer it makes sense to skim all kinds of math books. If you are a mathematician then I would say rather look for something that gels well with your personality and run with it.
I could be missing the plot here, but I always got the impression that Outlook limits (sets) the fonts and colours in order to make the emails look like they "were sent by MS/Outlook". But again, this may be my idiosyncratic MS experience.
1. At setup, Find My generates private key shared to all your Apple devices.
2. The private key generates a perpetual sequence of public keys. These change (iterates to the next) "frequently".
3. The rotating public key is shared accross all (including other people's) Apple devices via Bluetooth and can even do this when it's off.
4. The shared scheme pings to Apple's central system and uploads A. hashes of the public keys in the area and B. the location.
5. When you try to find a device you send your hashed public key to Apples server and they return the last picked up location (encrypted). (You thus need at least 2 Apple devices, one to find the other. Also, they don't say how the previously iterated public keys are remembered.)
Do you mean learn other people's songs from sheet music, or do you mean write down, from the sheet music, the same song again on blank sheet paper?
Edit: Or do you mean write down the song via hearing?
