    ...  That's sort of a take off on the joke that you don't have to outrun the bear, just your friend.

    Too often it seems we think we can rely on having big locks (aka "13 character passwords") on things.   But, often better is:
    1)  Security through obscurity
    2)  Immediate notification (such as when a sign on is attempted or a new device connected or especially if there is an invalid attempt.)

    For myself, I keep MAC authorization enabled so that, if I don't know your MAC address, you aren't getting in.
    This is really ridiculous. Your point about outrunning the friend and not the bear might have been true ten years ago (maybe) but it isn't today, when automated scans sweep every target in range, and are capable of trying many types of exploit.

    "Security through obscurity" is occasionally better than no security, but it's not better than any sort of real security. Immediate notification is basically useless in most contexts now due to attack volume. (If I looked at every time fail2ban banned an IP on a mailserver I'd never have time to eat or sleep.)

    As others have pointed out, your notion that MAC security does anything useful is risible.

    In short, this is an excellent example of why you should never take security advice from strangers on the internet. (Don't take mine, either. Pay a professional.)

  • Hands-on with Apple's new Core i9 iMac 5K with Vega graphics: benchmarks and first impress...

    JustSomeGuy1JustSomeGuy1
    So far, in sustained loads, the machine will maintain right around 3.9 GHz for long periods of time. I'll ask Andrew about fan noise, but given that he did the voiceover for the video with it blazing, it probably isn't bad.
    So that's pretty interesting. The earlier 5ks could get pretty loud. If this cooling system is the same... then presumably it can get loud too, and if it didn't, that means it's not being pushed. And if that's true, then you could adjust the fan speed curve to get more cooling at the top end, in which case... well, it depends on how Apple set PL1/PL2/Tau, and maybe some other things. I also vaguely recall reading how someone had messed with PL1/PL2 settings on Macs but I don't remember if it worked or not.

    Not complaining about the first writeup, but we could really use more info as you get it.

    1) The 9900k is well-understood, and you're claiming it doesn't throttle, but there's still more to be said: what speed will it sustain over long-term usage? Just rated, or is some boost still feasible? Either way, what do the fans sound like then?
    2) More benchmarks of the Vega! I have yet to even see anyone identifying what this chip is. Is it a cut-down Vega with 8 more CUs disabled, making it run at ~6/7th the speed of the Vega 56? (What about ROPs, memory type/bandwidth, etc.? I haven't seen anything at all on this hardware.) If not, what is it?
    3) Speaking of which, Unigine is fine (if we have the settings, as someone said above) but what would really be nice is a few comparisons! How does this stack up against the iMac Pro (V56/64) and previous iMac 5k?
    4) Did you find out if you can install a SATA disk in the SSD version? This is a pretty significant question. If you could stick a 2TB SATA SSD in there, then fuse it with the 256/512GB native SSD, that would make for a lot of very fast storage, much much cheaper than Apple's. How hard would it be to replace the HDD in the smallest fusion model (for those really on a budget)?
    5) Screen quality?
    6) Speakers?

  • Video: Galaxy S10e versus iPhone XR benchmarking showdown

    AI, this is starting to get embarrassing. You need to do better. You completely ignored the comments on your previous flawed benchmark article, and you're making the same mistakes here.

    So the A12 beats the 855 despite having half the performance cores.
    Why is that a surprise? That's what happens when you have a company building components in tandem, and optimizing those components for the software/firmware they're designed to use. It's no secret that Android is a complete disaster when it comes to efficiency. 
    You're entirely mistaken. This has nothing to do with vertical integration, Apple's software/firmware, etc. Those are good things, and important for device performance (as Samsung demonstrated last year on the S9 with their seriously busted scheduler) but they are irrelevant to the issue of underlying chip performance.

    The A12 is simply a vastly superior chip. In fact the A11 is competitive with the 855 (and the Kirin 980). This is purely a hardware issue. Someone here already posted a link to Anandtech, and I recommend you follow it. They're doing much better and more in-depth work on this topic than any other site.

    This AI benchmark article is surprisingly (and uncharacteristically) flawed. It should be updated.
