Bob Morales posted:I want to see benchmarks. Remember how slow the Intels were at running PowerPC apps with Rosetta I do remember, but I'm hoping they've improved the state of the art, or the speed will be 'good enough'. CPUs are a lot faster now, but lightweight applications are still lightweight applications. You wouldn't want to do serious computation through a translation layer, but you wouldn't want to do serious computation on a mobile-first device either. I'm thinking for example, MBP stays x86 as a desktop replacement, MB runs ARM with x86 translation for compatibility. The fewer x86 applications you run, the faster and more battery-friendly your experience. I'm just thinking out loud. Microsoft does a good job with research most of the time, so hopefully they find something that works. Photoshop being demonstrated being not-too-laggy is a good sign.

I'm wondering how well stuff that's targeted directly at the SIMD stuff (and worse, uses the ATI/NVIDIA GPU's) that can't be re-compiled for whatever reasons

I just finished installing a second SSD into my 2013 27" iMac. I was almost ready order the SATA/Power cable from hong kong and wait 30 days but I found I Fix Mac Computers and even though their website seemed pretty scammy with all the god references ( http://www.ifixmaccomputers.com/about-us-ifix-mac-momputers) I can attest that they are for real. Just be prepared for poor english grammar and Jesus fish/ power by GOD listed on everything

Do people commonly have admin accounts but use a separate user account on personal computers? Hadn’t considered it but was recently suggested to me

Ok is this something I can start doing now? I’m a little dumb sometimes. Like if I set up a new user account under my admin account will I have to set up a bunch of new stuff and like add safari plugins and download apps and poo poo for that user that are already on my admin user?

Why in the world would you do that? Your Administrator account isn't elevated by default, you have to enter your password as if you were a user account on the sudoer list. If you want to pretend like you are not an admin, never enter your password after you log in.

GoldfishStew posted:I’ve had it suggested multiple times and Apple suggests it on their site for security purposes For me, the reason to have another account is if you ever want a 'vanilla' account—if you run into an issue or somehow corrupt your user profile. That's not usually an issue, but if you are an 'under-the-hood' user, you may be changing your UID, or shell acount or messing with POSIX things. Having another account is like having another way to get into your house if the key to the front door breaks off in the lock and you can't get in. If you have an issue with your default profile, you can test it against the other profile and perhaps obviate the need to re-install the OS.

So, I guess that Intel CPU bug is going to be hitting us too https://www.theregister.co.uk/2018/01/02/intel_cpu_design_flaw/ No word from Apple about a patch yet, but no doubt one's coming. We didn't even have the opportunity to use AMD :/

Housh posted:The patch can slow computers down by 30%...wow...shouldn't this be big news everywhere? Well, it's big news among tech people, and it's really big news to anyone who operates cloud infrastructure. The reality is that most consumer workloads are not maxing out the CPU with syscall heavy tasks like lots of random DB reads, and no one benchmarks 'du -s' at home for shits and giggles. It won't really affect gaming or rendering or productivity or anything that isn't massively syscall heavy, and PCID on more modern chips (4th gen forward I think) can reduce the overhead by avoiding TLB flushes. Current synthetic benchmarks of the Linux KPTI/FUCKWIT patch put the impact at anywhere from 5 to 50% and I personally only heard about this late last night and I try to keep on top of stuff like this so ---- it'll get there. We don't really know what the real world impact is going to be.

I looked pretty long at the Dell XPS 13 and some of the ThinkPads when I was getting my 2016 mbp. Superior battery life and less concerns about screen/build quality kept me on the Mac. I do backend web app stuff so most everything I rely on is open source & cross platform and I know linux/freebsd as a server pretty well. I've had Fedora Workstation installed in a VM to get a feel for using it as a desktop. The one sticking point on the software side is 1Password. I use the old localvaults at home and we use 1P For Teams at work heavily. They've only recently begun to address this with a CLI tool and completely browser based app but it so far it requires the subscription service (not a dealbreaker but something I'm delaying as long as I can), and it's Chrome-only (absolutely a dealbreaker)

I have been away from macs for several years and would like a sanity check. I have a late 2011 15 inch MacBook Pro that has been sitting around, and I am thinking about bringing it back out of its hibernation. I had a lot of slowdown issues in it that made it nearly unusable back when I stopped using it, and I never investigated them, but I just updated to High Sierra after turning it back on, which seems to have fixed the problem, whatever it was. Any reason this can’t be a workhorse today? I imagine battery life won’t be what I expect on a new laptop, but I don’t need it to. It has a 2.5ghz chip (i7-2860QM), which benchmarks competitively to today’s chips. If I go from 4gb of ram to 8? 16? And replace the hard drive with an SSD (or replace the dvd with an SSD, seems like an option), then am I missing anything where this should still work like a champ for several years? I haven’t kept up with OSX changes, so I would hate to spend the money and realize then that I am missing a bunch of modern features that are the best parts of MacOS. Best I can tell, now Thunderbolt 3 is a big thing, but i don’t have new peripherals, and the new SSD file system, which getting an SSD installed should take care of. I don’t really have a used case for the computer or spending the money, and it looks like about $300 for 16gb of ram and a 500gb SSD, or about $190 for 8gb/ 256gb SSD. Maybe use it to do editing of my iCloud photos, but I have Lightroom on my PC, so that’s not really necessary. I might be better off selling the laptop and buying a newer model to be a toy spare Mac, or just putting it back in the drawer. If I were to go through with the refresh though, anything I’m missing? Thanks!

One of the reasons I got away from using it. Probably going to die again with actual use, or with a replacement might I be good? Edit: looks like Apple repaired it in 2014 and again in 2015 due to graphics screwups. Tewdrig fucked around with this message at 22:28 on Jan 3, 2018 |

Gaming devices will be impacted by using a KAISER variant to mitigate, any driver call still uses syscalI() to one degree or another. It doesn't matter since KAISER doesn't address either Spectre exploit, just Meltdown. To me the Spectre exploits are more devastation since those appear to be an issue related to CPU architecture in general. Intel, AMD and ARM vulnerable to Spectre.

SourKraut posted:Isn’t the OSX fix only applicable to Meltdown? I’m pretty sure OSX is still affected by Spectre also. I haven't really looked into any new info yet today, since I was up all night doing a breakdown of this for management at work. Double Map explicitly protects against meltdown. Spectre is different since it leverages exiting user mode programs to do the lifting and targets user memspace. It's going to require patches for the actual programs that can be leveraged (hopefully before, but likely after a program is discovered to be vulnerable to exploitation). quote:Meltdown breaks the mechanism that keeps applications from accessing arbitrary system memory. Consequently, applications can access system memory. Spectre tricks other applications into accessing arbitrary locations in their memory. Both attacks use side channels to obtain the information from the accessed memory location. Personally to me Spectre is worse, because it can be leveraged to reveal sensitive information like passwords or other private data in the user's memspace. from the Spectre white-paper: quote:We created a simple victim program that contains secret data within its memory access space. Next, after compiling the victim program we searched the resulting binary and the operating sys- tem’s shared libraries for instruction sequences that can be used to leak information from the victim’s address space. Finally, we wrote an attacker program that exploits the CPU’s speculative execution feature in order to execute the previously-found sequences as transient instructions. Using this technique we were able to read the entire victim’s memory address space, including the secrets stored within it. I mean the ultimate fix for this is a change to CPU architecture, which can take years.
