  • Other then legacy and uefi does it have a CSM compatibility support mode? An option to enable usb initialisation before bios? Eg wait for usb initialisation?

    Some “boot faster” options kind of reorder boot initialisation to a point where it’s not holding the system back.

    Though I’m really running out of suggestions… I can imagine you’re pretty frustrated. I know my Dell laptop was a pain to get the right settings to get usb to boot and the stupid 100db beep to silent on boot interruption.



  • I suggest a few more things:

    Try a different brand usb. Different motherboards sometimes don’t support some usb brands. In fact, a Lenovo server I rebuilt refused to boot off certain usbs.

    Some motherboards don’t initialise boot off some usb ports. Sometimes the additional ports are on another controller and initialise too slow.

    Just try a straight working Ubuntu live boot usb to remove any ventoy from equation. Ubuntu has real signed uefi (and no shim) granted by Microsoft. I think that’s how it works, uefi is a mess.

    Try to start isolating all the different factors, and there could be more. It doesn’t necessarily mean anything definitive if it works on another machine.



  • Hmm, so, policy in our office is a clean desk. Before you jump to conclusions, it’s because our secured area and office occasionally has people come through that should absolutely not see what information we have on our desks. This requirement is a compliance issue for our continued contracts and certifications.

    Our work from home policy hasn’t addressed this issue, but it sounds like it’s a clear gap. Your neighbour coming around for a cup of tea absolutely should not be able to see any work related information.

    My assumption is that someone has considered this kind of aspect and had a check to confirm that they’ve done diligence by asking you to reveal your working space. A space the companies sensitive information would be visible. Actually you too should maybe not be looking at your wife’s screen nor materials on her work desk. Depending on the situation.

    Either way, policy comes first so perhaps her employment agreement or employee handbook would reveal more.




  • For me I want to know how much frame latency there is since I’m suspicious and I want to try things to see the effect and I just don’t know how to get that information in an OSD like I can with msi afterburner.

    If someone knows what can do this in Linux, please reply!

    Instead I just stopped all competitive and cooperative gaming. Which is a bit of a shame. Sometimes I’ll load up windows to join friends but usually by the time I’ve updated whatever game I’ve gotten over it.

    Don’t get me wrong, hiccups aside I’m very happy which is why I’m in Linux most of the time. But it’s not always a wonderful world.


  • This will be able to do cross site (apps) information collection within other sites (apps) in this profile. The way this works is one of many, and complicated so: https://blog.mozilla.org/en/products/firefox/cross-site-tracking-lets-unpack-that/

    The idea of profiles is to stop this behaviour and other behaviours through isolation. Along with other practices makes up a privacy-in-depth (layered) approach. It doesn’t solve everything.

    For example if you are in the same house sharing an internet connection, it is possible to say “at least one outstation in this house (IP) are interested in ‘x’ and therefore I should target everyone in that house because people who live together are interested in similar things”. Even if you isolate, you could still teach a data hoarding company like meta you like something simply by them by necessity needing your IP to communicate.

    Some people try to say ‘I’ve got a VPS with a VPN to communicate all traffic through’ but that doesn’t add any privacy, your exposed VPS with its IP is an IP only for you and still all collected information about you would be able to be thumbprinted to that IP across many services (eg instagram whatsapp and Facebook). A public VPN provider in this case adds a layer of obfuscation since you can change your IP rapidly and it’s an IP that’s shared with other unrelated users. Which is exactly why many services like reddit are banning access from them under the guise of “oh training data leaks from VPN, and we want to sell it” bs.

    Anyway it’s a tough world out there to be private. I’m at an age where after 10 years without Facebook and I never had instagram, everyone knows I’m contactable via sms. It’s not secure, it’s barely private, but I don’t really “chat” except at the pub. So that’s where they ask me to visit. Lol.




  • A software shouldn’t use passwords for tls, just like before you use submit your bank password your network connection to the site has been validated and encrypted by the public key your client is using to talk to the bank server, and the bank private key to decrypt it.

    The rest of the hygiene is still up for grabs for sure, IT security is built on layers. Even if one is broken it shouldn’t lead to a failure overall. If it does, go add more layers.

    To answer about something like a WiFi pineapple: those man in the middle attacks are thwarted by TLS. The moment an invalid certificate is offered, since the man in the middle should and can not know the private key (something that isn’t used as whimsically as a password, and is validated by a trusted root authority).

    If an attacker has a private key, your systems already have failed. You should immediately revoke it. You publish your revokation. Invalidating it. But even that would be egregious. You’ve already let someone into the vault, they already have the crown jewels. The POS system doesn’t even need to be accessed.

    So no matter what, the WiFi is irrelevant in a setup.

    Being suspicious because of it though, I could understand. It’s not a smoking gun, but you’d maybe look deeper out if suspicion.

    Note I’m not security operations, I’m solutions and systems administrations. A Sec Ops would probably agree more with you than I do.

    I consider things from a Swiss cheese model, and rely on 4+ layers of protection against most understood threat vendors. A failure of any one is minor non-compliance in my mind, a deep priority 3. Into the queue, but there’s no rush. And given a public WiFi is basically the same as a compromised WiFi, or a 5g carrier network, a POS solution should be built with strengths to handle that by default. And then security layered on top (mfa, conditional access policies, PKI/TLS, Mdm, endpoint health policies, TPM and validation++++)




  • I knew a Datacenter that had hundreds of ps3s for rendering fluid simulation and other such things that at the time were absolutely cutting edge tech. I believe F1 and some early 3d pixar stuff was rendered on those farms. But like all things, technology marched on. fpgpas and cuda have taken that space.

    Cell definitely was heavily used by specialist/nichr industry though.

    I wonder if I can find you some link to explain it better than the rumours I heard from staff that used to work in those datacentres.

    Hmm hard to find commercial applications, probably individuals might have blogged otherwise here’s what I’m talking about: https://en.m.wikipedia.org/wiki/PlayStation_3_cluster



  • Well, what I really wonder is if because the kernel can include it, if this will make an install more agnostic. Like literally pull my disk out of a gaming nvidia machine, and plug it into my AMD machine with full working graphics. If so this is good for me since I use a usb-c nvme ssd for my os to boot from on my work and home machines and laptops for when I’m not worrying. All three currently have nvidia cards and this works ok. I have some games to chill and take a break. My works core OS for work MDM etc unmodified. I like it that way.

    I realise this is not a terribly useful case, but I could see it for graphically optimised VM migrations too not that I have many. Less work in transitioning gives greater flexibility.

    Ah you’re thinking I’m reading your other comments to other people.

    BTW HIPAA is for providers for their patients information handling. Once it’s in the person’s hands, it’s no longer under HIPPA and it no longer applies. If you decide to put your private medical information on a commercial advertisement board on a highway, and it’s not breaking laws to do with acceptable adcertisement (eg gore or smut) you’ll be able to do that to.

    Basically theres no expectation for a individual person to adhere to HIPPA for their own personal information storage and it doesn’t apply.

    My assumption with your lawyer comment, is this was a insurance or otherwise medical malpractice lawyer who might collect this information for their client cases, since without having client/patient requirements, HIPPA is irrelevant.
