Was arrested for DUI, but that's not my main concern. I have been bombarded with phone calls, texts, and mail from lawyers and insurance companies. Where did I consent to my information being sold?

I have hit what I think is a BIOS bug. I want to know if others can reproduce it. If you have 24/32 GB memory for w530, and set the display settings in BIOS to "integrated only" and "disable os detection for optimus", the machine performs 10X slower or worse (rough estimate, but I can do more precise debugging later). It's very apparent and independent of the OS. Can anyone check ?

I have a simple choice plan with 10 lines. After some back and forth with the website, store and phone, it turns out that although my account allows adding more lines up to 12 in total, the plan doesn't. The website errors out, and even the reps get an error at the end. This is a simple choice plan with 2.5 (currently 4) GB data per line. I don't want to switch plans.

I have the grandfathered family stateside international + mobile add-on to my simple choice plan which was offered only for a short period. It works fine for the most part. However, when calls aren't free, the rates are supposed to follow their website (https://www.t-mobile.com/coverage/international-calling). It turns out that I am being billed different (higher) rates than the website. Perhaps the grandfathered plan follows a different rate, but I can't find any other rates published on t-mo's website. Fortunately, my charges weren't that high, and the rep I spoke to was nice enough to do manual adjustments to the bill. I would like some official documentation from t-mo on this if someone

This affects at least W530 with 32 GB RAM, and possibly others.

To check if you are affected: On a system with latest microcode and OS updates, run:

dmesg | grep -i l1tf

If you see the following messages, you are affected

[ 0.038426] L1TF: System has more than MAX_PA/2 memory. L1TF mitigation not effective.

[ 5.421833] L1TF CPU bug present and SMT on, data leak possible. See CVE-2018-3646 and

https://www.kernel.org/doc/html/latest/admin-guide/l1tf.html for details.

The workaround will likely need a mem argument in grub. Relevant bug report:

Affects all distros since it's a kernel bug

Since there haven't been any successful posts regarding this setup, I'm sharing this so that others can try and improve this. This should work on at least a few thinkpads.

Laptop: Thinkpad W530, Card: Quadro K2000M

What works (so far): Linux host, Linux guest with nouveau driver

Setup: Pretty standard. Luckily, the IOMMU group is isolated with only the GPU and a bridge in it. GPU can be passed through without too much trouble.

Main challenges:

• GPU vbios isn't easily accessible in this setup since it's not on the card. It's a part of the system bios, which the driver is supposed to read through ACPI calls.
• There are a few ways to extract it. I tried nouveau's debugfs interface fir

I've never been able to get tab completion to work well for RHEL repos. My clients are connected to Satellite. Is there some setting on Satellite to enable this ? I'm not talking about the feature in general. It works on CentOS/Fedora, and it even works for public repos that you install yourself. I have bash-completion & bash-completion-extras. The problem is specifically with RHEL channels. It appears that clients never cache the contents, or do something else terribly inefficient. So every time you hit a tab, "/usr/bin/python -t /usr/share/yum-cli/completion-helper.py" will spike up to 100% CPU for a good 30 seconds after which it'll come back with the auto-complete suggestions. It's p

Disclaimer: I don't have much experience with apache or php, but I am comfortable with linux systems.

I have setup rtorrent + rutorrent in the past for a single user. In the standard configuration, which you'd see in most setup guides, the php scripts would run under the apache user. This also means giving apache some permissions to access the user's home directory. This is not ideal, but it can be mitigated a bit with selinux. You set the http context only for a few directories under the user home that apache needs access to.

However, I think this approach doesn't sound too good for multi-user scenarios. If through an exploit, you can get get the same privilege level as apache, you would

I've seen a clip of this show posted on reddit. I remember it as British, but it could've been anywhere from that region (Scottish, Irish, etc.). I don't remember the accent too well, but the style of humour was quite British. It has a female lead who has a very deadpan style, and she interviews people. She is some sort of a reporter/journalist. In the clip that I remember, she asks a constable various things about the law, and something along the lines of, "Can you arrest yourself ?". This would have been a show from the 80s or 90s going by the quality of the video that I remember.
