  1. There's always two camps of PC Gamers: one who declares the next "Crysis" is some game, and another who says the same game is horribly unoptimized.

      On a side note, Crysis itself is not optimized to scale on today's hardware, so I guess both sides are technically the same thing 🙃

      If I ever do LED for looks, I’ll make sure I can like play movies & stuff with it. 


      Maybe install a laser light show with like lights that move up & down like a rave haha. 

      At Linus tech, get on it Haha.

  3. Have fun not sleeping tonight post part something: https://medium.com/hackernoon/im-harvesting-credit-card-numbers-and-passwords-from-your-site-here-s-how-9a8cb347c5b5


    tl;dr, it's possible to inject code into an NPM module that does bad things, and almost nobody would be able to A: notice or B: figure it out.

      This update brought to you by Privacy.com! And Honey! 

  4. Seeing some more PS5 news made me think "can't wait for the so-called 'console killers' that people attempt"


    Because so far nobody's been able to make one that isn't a joke. (Well I mean, they're serious, but to me it's laughable)

    1. Sauron


      That's why I used to make "alternatives" rather than "killers" - until both AMD and Intel just gave up on low end CPUs.

  5. iFixit updated the 2019 Mac Pro teardown by taking apart MPX module for the video card.


    Holy bare bones board Cook:

      It may be a trick of the eye by the fact MPX boards are large, but here's a Sapphire RX 580 for reference:


    2. Windows7ge


      Based on the position of both those connectors I would beg to guess the power delivery and most of the control circuitry for the display ports are on the motherboard.


      If that sounds accurate it's beyond me why any manufacturer would do that. But I mean, hey it's Apple, "Think different!" am I right?


      But then again it kind of makes sense. They wouldn't want you plugging their GPU in another vendors board. Best way of doing that, don't put all the components on the card.

    3. Mira Yurizaki

      Mira Yurizaki

      @Windows7ge I think you're right. The two chips marked yellow are DP to HDMI converters and the card only has HDMI outputs.


      A few DP connections are probably being routed back to the MPX slot to feed the Thunderbolt controllers.


  6. When I'm bored, I think about why communication standards measure in bits per second rather than bytes per second:

      So it's NOT  just because bigger number is better? Interesting

  7. More random thoughts of the day! Well more like one.


    RDNA 2 GPU goodness

    Considering Microsoft confirmed the Xbox Series X uses RDNA 2, and it's basically all but confirmed going to be in the PS5, and with both companies spouting out ray tracing capabilities, it looks like this year AMD will hop on that ray tracing bandwagon. And it looks like RDNA 2 will support other DirectX 12 features like Variable Rate Shading.


    So it looks like Navi was AMD's Maxwell 1. Hopefully this means games in the future will start taking advantage of these new features.

  8. Random thoughts of the day (I wonder if I should make this into a blog series, but you know, I keep doing that)


    On CacheOut

    At the surface it sounds scary: An exploit that can dump data anywhere in the processor even in so-called secure enclaves. But before people start panicking it's helpful to take a step back, breath, and take hopefully calm approach to looking at this.


    To me, security is ultimately about the following: risk management. I know that I cannot completely secure a system. I'm also human who's lazy and would do the minimum amount of work as possible. So security becomes the following:

    • How valuable is the thing I'm trying to secure?
    • How much of a problem is it if someone gains access to the thing I'm trying to secure?
    • How often do I need the thing I'm trying to secure?

    Depending on how I answer it, I may be more relaxed or more strict with what I'm trying to secure. For example, throwaway online accounts aren't valuable, wouldn't be much of a problem if someone gained access to it, and frequency of use is sort of irrelevant. So I wouldn't implement something like 20 random character passwords and 2FA. But say an email account I use that's valuable, is a problem if someone gained access to it, but I use it often. I will use a hard password and 2FA, but I relax 2FA to be used only on the first login.


    In addition to those questions, the following information is also valuable in assessing risk:

    1. What I know ("Known knowns")
    2. What I don't know that I'm aware of ("Known unknowns")
    3. What I don't know that I'm not aware of ("Unknown unknowns")

    The goal is to obviously minimize #3 and #2. But even if I have a lot of knowns but few unknowns in general, that doesn't make something insecure by default. If anything, having more knowns means I can formulate mitigations and contingency plans should they be exploited. #2 is hard to form mitigations or contingency plans for and #3 is practically impossible.


    In any case, my take on CacheOut is this:

    • For a home user, they're likely not going to be targeted as this attack is for focused pinpoint pieces of data. This is useful for someone who wants the keys to a data vault.
    • According to commenters on Y Combinator, this is an exploit of the TSX system, which is off by default in most cases.


      Before people get all nutty as usual:

      This is another TSX (transactional memory) issue, and you can disable TSX without much of a problem.


      The attacker basically needs to be running a binary on the machine (not JS in a browser or anything).


      The leakage is extremely slow, about 225 byte/minute for ASCII text (a 4k page in 18 minutes). I'm not sure if that was an exact recovery either, just a probabilistic one. With noise reduction to enhance recovery, they said it took twice as long - so about 113 byte/minute.


      It seems to be able to only be able to control the bottom 12-bits of the address to recover (but I didn't fully get why) and require the process to be either reading or writing the data to get it into L1 cache somehow, so just sitting in RAM isn't good enough.


      attacker still needs to figure out an address (even with ASLR there is still a lot of guessing, and if you have really sensitive data, just move it every second until you wipe it).


      Interesting, but kind of a non-issue.

      I wouldn't call it a non-issue, but if this is the characteristic of the attack, it makes home users less of a target.
    • Also keep in mind that just because an exploit can't happen on one system, doesn't mean it's not exploitable in another way. Often these exploits are focused and poke at something with the architecture implementation itself. So while the AMD crowd may be cheering on, I feel the potential for issues with AMD is just as large because of how few known knowns there are about Zen.

      Remember, even a few years ago we didn't know about speculative execution attacks.


    On Sonos and the idea of "planned obsolescence"

    I sort of glazed over the specifics of what happened, but the idea of "planned obsolescence" was thrown around enough that I thought I'd throw in my own input.


    The first part is what even is "obsolescence." Is something obsolete the moment something better comes out? Then this raises question of if Core i5s are obsolete because Core i7s exist. Though people would go "no we mean when the next gen comes out." So if we add in the word "planned" meaning the company had a plan to do something, then wouldn't "planned obsolescence" apply to everything damn thing? Lots of companies are planning on making a new, better product, so by the letter of the phrase, everything has planned obsolescence.


    Okay, so obviously I'm gaming the argument here. But I'd argue that just because a company doesn't want to support a product anymore doesn't make it "planned obsolescence" as long as the product can still work as a stand alone product. I did read somewhere that supposedly if you put one of Sonos's unsupported speakers online, it'll "brick" the speaker, but that's reaaaaaallly silly. Any company that tries to pull that off will have a fast track ticket to a class action lawsuit (which won't help the consumers, but a major expense is a major expense) and/or a fine from the FTC.


    But if someone is butthurt that older products won't get new features... okay, well what do you want the company to do? You may as well complain that Microsoft isn't supporting Windows 10 on your 20 year old Pentium III machine. If they're taxing the microcontroller inside of the speaker to the limit, there's not much else you can do. I mean, you could swap out the board for another, but that's not something you should expect an end user to do. Plus it'll probably cost an arm and a leg anyway.

      Yeah you should definitely make a blog series, good food for thought!

      I’ve a few. I wouldn’t use them because idk how long the springs will hold up. Additionally IF I can find someone that could repair it, idk how much that’ll cost. 


      They're cool heirlooms though. 

    3. TVwazhere


      I actually think they're pretty cool. I showed interest in my fathers that he got as a teenager in high school, and as a high school graduating gift they got me my own....


      About a year later the fucking hands fell off the middle spindle and were resting at the bottom of the glass LOL 😂

      That's more interesting than the Indian head penny I found on the floor one day at work. Printed in 1903. Doesn't have significant value.

  10. If you're using a GeForce card and don't want to deal with DCH drivers, which require the Control Panel to be installed from the Microsoft Store, NVIDIA still provides so-called Standard Drivers at https://www.nvidia.com/Download/Find.aspx?lang=en-us


    If you installed a DCH driver, you will need to uninstall it first. You may need to run DDU as well to ensure Windows doesn't try re-install the DCH driver.

      I think i'm going to purchase a new build and give my son my pc, but i will probably upgrade the gpu for him to a 970 or 980. @Mira Yurizaki

  11. Cyberpunk 2077 is delayed because "console limitations" https://comicbook.com/gaming/2020/01/23/cyberpunk-2077-ps4-xbox-one-release-date-delay/


    I mean, if you were planning on releasing to the PS4/XB1, you should've known what you were signing up for. Especially since The Witcher 3 is on them.

      right. Although, id rather wait longer than sooner to get a game that isn't broken and is fun to play. Although i don't believe this is for changes to story as much as platform issues. I'll give them the benefit of the doubt for now, do to their past title, but they really should of stradegized better then they did.

    3. Mira Yurizaki

      @dizmo Whether or not a game's developers ultimate ambitions are for a game is irrespective of how much they know about the system they're targeting. If they didn't learn anything about the system, which for all intents and purposes didn't change, when developing an application on it, then I don't know what to say other than they're incompetent in that regard.


      Also "performing at its best" would require you to develop from the baseline requirements anyway, because if it performs really fast on lower end hardware, it's going to perform even better on higher end hardware. Developing on lower end specifications first doesn't mean the game is going to suffer. Look at Cry Engine 3. It's designed to work on the Xbox 360 and PlayStation 3, and yet Crysis 3 was a beast to run at maximum quality. Or heck, we could look at id Tech 6, designed to run at 1080p 60 FPS on the OG PlayStation 4 and Xbox One, but you can easily achieve 200+ FPS with maximum detail on a PC.


      If you set your baselines on higher-end hardware... well uh, your baseline is for the higher-end hardware. Maybe by some fluke going lower-end in hardware spec won't really hurt the base performance goals that were set, but that's the exception, not the rule.

    4. dizmo


      Oh I see. So you expect them to know how a new engine is going to work on a platform they haven't used it on. Got it.

      Sure, but if you're aiming at low end hardware there are features you simply aren't going to work that hard to implement, as they won't work. I'd still rather them have it set at a higher level than last gen consoles.

  12. Running an NES on nothing but AA alkalines be like 😎


  13. What if working on the PlayStation 4 and Xbox One inspired AMD to create the socket AM4 platform?

    1. imreloadin


      I'm pretty sure the failure that was AM3 was what actually inspired them😂

    2. Mira Yurizaki

      Mira Yurizaki

      AM3 was a decent platform. I would argue maybe FM2 was a disaster, but that was just an APU centric AM3.

  14. "AMD jebaited itself"

      Also I sort of question Steve's words on NVIDIA killing the 1660 Ti so that AMD would've been forced to compare it to the 1660 Super. I'm sitting here going "What is this then?"




    2. tophercrunch


      Thats funny i just saw that video card too and was questioning this @Mira Yurizaki

      Honestly, I thought it was going to be about Google search results going towards the Nvidia 5600.

      Why doesn't it show storage space utilization for you? Do you have your drives set as dynamic?

      My SSD gets close to 60ºC easy when I'm gaming, it sits directly under the GPU.

      You can do excellent surround or even directional audio effects just with two channels in headphones. I think the problem was no one wanted to take advantage of it because it requires more thought than just regular stereo.

      @Tech_Dreamer I wouldn't say it has it's limits, because if you can mix using binaural techniques, then it's physically accurate to how you would actually hear it.


      But few, if any, applications and media actually employ this technique.

      Worked for me, without headphones :D I don't have a good pair to test with, so can't speak for the headphone experience 😅

  23. New idea for my unicorn monitor to make it less unicorn: using white microLEDs in a full-array backlight for LCD panels instead of using RGB microLEDs only.
