    Chunchunmaru_ got a reaction from SlimyPython in Linux 5.1 kernel hit by SSD TRIM bug which causes massive data loss   
    Summary: Looks like there is a bad commit in the Linux 5.1.2 kernel, which in some circumstances issuing a ATA TRIM causes actual data to be discarded instead of deleted blocks.

    Looks like Windows 10 is not the only one to get data loss after updates.

    So far, it appears the issue happens if:
    LUKS+dm_crypt if:(Linux kernel software encryption) A Samsung SSD is used Linux 5.1.2 is used  

    It should be noted that this happens only when ATA TRIM is issued, so when the "discard" fstab option is used or the weekly "fstrim" service cron/systemd timer is enabled, or a manual fstrim is issued through CLI.

    Ubuntu based distros should not be affected by this as it doesn't use the Linux 5.1 kernel.

    Arch Linux/Manjaro users sadly are affected, on Manjaro the fstrim is enabled automatically, while on Arch it has to be issued or configured manually.
    I do not know if other distros are affected

    Since it's a bug related to the device mapper, this could happen on any filesystem

    Mitigation: The best thing you can do is to shut down the system immediately and use another kernel.
    You can also try disabling the fstrim timer by issuing this command, but it's not very recommended:
    `systemctl disable fstrim.timer` `systemctl stop fstrim.timer` Or if you are an expert, checking in /etc/fstab for the discard parameter (but you are basically screwed up if you have this enabled as it's a continuous trim)
    Remember for your SSD health and optimal performance, to re-enable those options once everything is over by just replacing disable with enable, and stop with start.

    That could actually mean there are more people in the security team for finding vulnerabilities, which would be reasonable, still better than if someone else or hackers finds out by themselves

    Chunchunmaru_ reacted to GoodBytes in Zero day exploit in windows 10 1903   
    Also, the graph has issues.
    Windows 7 and Vista should be together as Windows 7 was mostly polishing Vista interface, and a few new features here and there which many of them if not all, doesn't affect security, and the removal of Vista Gadgets which was found to be a big security issue.
    Windows 8 has much less users, so you have less attention by security experts.
     
    Another thing to consider, is that security issues can date back to older version of Windows, so how where do they position the security flaw? In this situation, do they mark it on current version of Windows even though it might work for Windows XP (for example), or they mark it for the first version of Windows with the security flaw.

    Not really anonymous. It's from SandboxEscaper who has done similar things in the past. It's a very troubled individual which basically hates western counties and have several exploits up for sale, but only to "enemies of the us".

    Chunchunmaru_ reacted to TrigrH in [PC] Borderlands 2 Help   
    Borderlands 2 solo is quite easy, let me give you some key points of information:
    Level is everything, if the enemies are more then 2 levels higher than you, you're fucked. Do side quests to get your level above the enemy if your are struggling.
    Focus lower capacity and faster charging shields, so you can use cover to regen at mitigate damage.
    Keep swapping to more and more powerful weapons.
     
    If all the above fails, send me your sav file and I can change the class and skills so you don't need to make a new character.

    I wanted to point out this bit (and speaking in general). People seem to forget that turbo clocks aren't supposed to be guaranteed, but base clocks should be. If the computer can't maintain base clocks, then we have a problem.

    My guess is they use porting layers from DirectX to OpenGL which could increase the overall hardware requirements

    Anyway, as I said try what I said here
    Remember to press ESC as soon as possible, this should immediately show a verbose output, try also to remove "quiet" and "splash" parameters, if it still doesn't work

    We should all remember that Microsoft are in fact convicted criminals who has at several points in the past been brought to court for things such as EEE and been found guilty. 
     
    I wouldn't really say this is fear mongering as much as it is being cautious and reminding people about Microsoft's history.

    You're assuming that they actually make changes (extensions) to improve their product. However, several times in the past it has been the case where changes were done for the sole purpose of making things more difficult for competitors.
     
    I am all for competition, but EEE has in the past been more about making competing solutions worse rather than improving one's own product. When that happens, it's bad.
     
    And you also have to think of interoperability, which is a very valuable asset. Even if for example J/Direct (one of Microsoft's attempts at EEE) had offered some benefit over JNI, the pros of that approach (I don't think there were any) should have been weighted against the drawback (it ruined cross compatibility, which was the entire point of Java).
     
    And if you try to argue that Microsoft just tried to improve Java, please keep in mind that J++ (Microsoft's now discontinued version of Java for Windows) actually had fewer features than the one offered by Sun.
    Microsoft went "oh you want to use that feature? Sorry but that doesn't work on Windows" and as a result, programs which ran on things like GNU/Linux and MacOS would not work on Windows. And because of that people stopped using those functions even though they were useful.

    It's entirely possible to do EEE even though something is open source.
     
    That's because open source doesn't offer any protection from EEE. And don't call it "fear mongering" when it has happened over, and over in history. Hell it's still happening these days. If you want a real world example of this look no further than Google and web standards.
     
    KHTML, the browser engine developed by the KDE project, was and still is open source and forked over to WebKit by Apple, which kept it open source.
    WebKit was then forked to Blink by Google, and it is open source.
     
    It's open source all the way through. Yet here we are, with Google creating their own web standards and protocols which can negatively impact other browsers.
     
    I am sure even folks over at Microsoft would agree that what Google is doing with the web is a form of EEE, despite all of it being open source.
     
     
     
     
    I don't see why they would need to do a custom Kernel for that to work though. That should be handled through Kernel modules. But maybe that is what they mean by "custom Kernel". I guess it remains to be seen. I am skeptical though.
     
     
    WinAPI is alive and well, and will most likely be the primary tool for a majority of Windows developers for years to come. Microsoft are still introducing new features to it.

    Then they want to use Windows. I know that many people wrongly assume that Windows was a bad thing to use. Using Windows applications is not really better on any other OS.
