Privacy renzev • 2 months ago • 100%

I've just been playing around with https://browserleaks.com/fonts . It seems no web browser provides adequate protection for this method of fingerprinting -- in both brave and librewolf the tool detects rather unique fonts that I have installed on my system, such as "IBM Plex" and "UD Digi Kyokasho" -- almost certainly a unique fingerprint. Tor browser does slightly better as it does not divulge these "weird" fonts. However, it still reveals that the google Noto fonts are installed, which is by far not universal -- on a different machine, where no Noto fonts are installed, the tool does not report them. For extra context: I've tested under Linux with native tor browser and flatpak'd Brave and Librewolf. What can we do to protect ourselves from this method of fingerprinting? And why are all of these privacy-focused browsers vulnerable to it? Is work being done to mitigate this?

Hi all! I recently built a cold storage server with three 1TB drives configured in RAID5 with LVM2. This is my first time working with LVM, so I'm a little bit overwhelmed by all its different commands. I have some questions: 1. How do I verify that none of the drives are failing? This is easy in case of a catastrophic drive failure (running `lvchange -ay <volume group>` will yell at you that it can't find a drive), but what about subtler cases? 1. Do I ever need to manually resync logical volumes? Will LVM ever "ask" me to resync logical volumes in cases other than drive failure? 1. Is there any periodic maintenance that I should do on the array, like running some sort of health check? 1. Does my setup prevent me from data rot? What happens if a random bit flips on one of the hard drives? Will LVM be able to detect and correct it? Do I need to scan manually for data rot? 1. LVM keeps yelling at me that it can't find `dmeventd`. From what I understand, `dmeventd` doesn't do anything by itself, it's just a framework for different plugins. This is a cold storage server, meaning that I will only boot it up every once in a while, so I would rather perform all maintenance manually instead of delegating it to a daemon. Is it okay to not install `dmeventd`? 1. Do I need to monitor SMART status manually, or does LVM do that automatically? If I have to do it manually, is there a command/script that will just tell me "yep, all good" or "nope, a drive is failing" as opposed to the somewhat overwhelming output of `smartctl -a`? 1. Do I need to run SMART self-tests periodically? How often? Long test or short test? Offline or online? 1. The boot drive is an SSD separate from the raid array. Does LVM keep any configuration on the boot drive that I should back up? Just to be extra clear: I'm not using `mdadm`. `/proc/mdstat` lists no active devices. I'm using the built-in raid5 feature in lvm2. I'm running the latest version of Alpine Linux, if that makes a difference. Anyway, any help is greatly appreciated! --- How I created the array: ``` pvcreate /dev/sda /dev/sdb /dev/sdc vgcreate myvg /dev/sda /dev/sdb /dev/sdc pvresize /dev/sda pvresize /dev/sdb pvresize /dev/sdc lvcreate --type raid5 -L 50G -n vol1 myvg lvcreate --type raid5 -L 300G -n vol2 myvg lvcreate --type raid5 -l +100%FREE -n vol3 myvg ``` For education purposes, I also simulated a catastrophic drive failure by zeroing out one of the drives. My procedure to repair the array was as follows, which seemed to work correctly: ``` pvcreate /dev/sda vgextend myvg /dev/sda vgreduce --remove --force myvg lvconvert --repair myvg/vol1 lvconvert --repair myvg/vol2 lvconvert --repair myvg/vol3 ```

Fun fact: Torx screwdrivers are compatible with Torx Plus screws, but Trox Plus screwdrivers are only compatible with Torx screws that are one size larger

Context: LaTeX is a typesetting system. When compiling a document, *a lot* of really in-depth debugging information is printed, which can be borderline incomprehensible to anyone but LaTeX experts. It can also be a visual hindrance when looking for important information like errors.

Brave Browser renzev • 2 months ago • 90%

# Update Apparently this *is* patched out by Brave, but it is enabled by default. See u/Engywuck@lemm.ee 's comment below! --- Vanilla chromium gives google's websites special treatment by offering detailed CPU info, among other things. This is implemented through a hidden browser extension. You can prove this by yourself by running `chrome.runtime.sendMessage("nkeimhogjdpnpccoofpliimaahmaaome", {method: "cpu.getInfo"}, (response) => {console.log(JSON.stringify(response, null, 2)); }, );` on google.com through the browser console. For me, it gives the following info: ``` { "value": { "archName": "x86_64", "features": [ "mmx", "sse", "sse2", "sse3", "ssse3", "sse4_1", "sse4_2", "avx" ], "modelName": "Intel(R) Core(TM) i7-2620M CPU @ 2.70GHz", "numOfProcessors": 4, "processors": [ { "usage": { "idle": 28238205, "kernel": 827581, "total": 32762960, "user": 3697174 } }, { "usage": { "idle": 1455131, "kernel": 743391, "total": 6209241, "user": 4010719 } }, { "usage": { "idle": 1448653, "kernel": 769970, "total": 6068506, "user": 3849883 } }, { "usage": { "idle": 1450274, "kernel": 744886, "total": 5948597, "user": 3753437 } } ], "temperatures": [] } } ``` Note that this doesn't work on other websites like lemmy.world, only google. What I am confused about is that I can replicate this behavior in Brave. Why does brave reveal this information to google, and to google only? From what I understand, it can be used for fingerprinting and tracking. Shouldn't this be patched out? Is my testing methodology flawed? Will this be fixed? Brave version: `Version 1.67.123 Chromium: 126.0.6478.126 (Official Build) unknown (64-bit)` running on linux via flatpak

Context for newbies: Linux refers to network adapters (wifi cards, ethernet cards, etc.) by so called "interfaces". For the longest time, the interface names were assigned based on the type of device and the order in which the system discovered it. So, `eth0`, `eth1`, `wlan0`, and `wwan0` are all possible interface names. This, however, can be an issue: "the order in which the system discovered it" is not deterministic, which means hardware can switch interface names across reboots. This can be a real issue for things like servers that rely on interface names staying the same. The solution to this issue is to [assign custom names based on MAC address](https://wiki.alpinelinux.org/wiki/Custom_network_interface_names). The MAC address is hardcoded into the network adaptor, and will not change. (There are other ways to do this as well, such as setting udev rules). Redhat, however, found this solution too simple and instead devised [their own scheme](https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/7/html/networking_guide/sec-understanding_the_predictable_network_interface_device_names) for assigning network interface names. It [fails at solving the problem](https://bbs.archlinux.org/viewtopic.php?id=245428) it was created to solve while making it much harder to type and remember interface names. To disable predictable interface naming and switch back to the old scheme, add `net.ifnames=0` and `biosdevname=0` to your boot paramets. The template for this meme is called "stop doing math".

Firefox on Debian stable is so old that websites yell at you to upgrade to a newer browser. And last time I tried installing Debian testing (or was it debian unstable?), the installer shat itself trying to make the bootloader. After I got it to boot, apt refused to work because of a missing symlink to busybox. Why on earth do they even need busybox if the base install already comes with full gnu coreutils? I remember Debian as the distro that Just Wroks(TM), when did it all go so wrong? Is anyone else here having similar issues, or am I doing something wrong?

Context: Permissive licenses (commonly referred to as "cuck licenses") like the MIT license allow others to modify your software and release it under an unfree license. Copyleft licenses (like the Gnu General Public License) mandate that all derivative works remain free. Andrew Tanenbaum developed MINIX, a modular operating system kernel. Intel went ahead and used it to build Management Engine, arguably one of the most widespread and invasive pieces of malware in the world, without even as much as telling him. There's nothing Tanenbaum could do, since the MIT license allows this. Erik Andersen is one of the developers of Busybox, a minimal implementation of that's suited for embedded systems. Many companies tried to steal his code and distribute it with their unfree products, but since it's protected under the GPL, Busybox developers [were able to sue them](https://en.wikipedia.org/wiki/BusyBox#GPL_lawsuits) and gain some money in the process. Interestingly enough, Tanenbaum [doesn't seem to mind](https://www.cs.vu.nl/~ast/intel/) what intel did. But there are [some examples](https://donatstudios.com/License-Grumbles) out there of people regretting releasing their work under a permissive license.

Explanation: Python is a programming language. Numpy is a library for python that makes it possible to run large computations much faster than in native python. In order to make that possible, it needs to keep its own set of data types that are different from python's native datatypes, which means you now have two different `bool` types and two different sets of `True` and `False`. Lovely. Mypy is a type checker for python (python supports static typing, but doesn't actually enforce it). Mypy treats numpy's `bool_` and python's native `bool` as incompatible types, leading to the asinine error message above. Mypy is "technically" correct, since they are two completely different classes. But in practice, there is little functional difference between `bool` and `bool_`. So you have to do dumb workarounds like declaring every bool values as `bool | np.bool_` or casting `bool_` down to `bool`. Ugh. Both [numpy](https://github.com/numpy/numpy/issues/18876) and [mypy](https://github.com/python/mypy/issues/10385) declared this issue a WONTFIX. Lovely.

Many "alternative" search engines are better for privacy, but they are still vulnerable to censorship, because they rely on g\*\*gle and m\*crosoft's indices for their search results. This isn't a deep-hidden secret either, many of them disclose what search index they use on the "about" page, for example: - https://duckduckgo.com/duckduckgo-help-pages/results/sources/ - https://support.startpage.com/hc/en-us/articles/5138782571796-Why-isn-t-a-particular-site-appearing-in-the-results - https://www.ecosia.org/privacy There are still search engines that (claim to) maintain their own index.

I recently wanted to run [tegaki](https://tegaki.github.io/), and my experience is pretty much summed up by the meme. I consider myself fairly tech-savvy, but I just couldn't figure out how to compile it. So I just gave up, downloaded the `.exe` and put it into a fresh wine prefix. After installing CJK fonts, everything ran fine. Now I'm trying to get [gpaint](https://www.gnu.org/software/gpaint/) to work. ~~My distro recently dropped support for `gtk+2` (which I am fairly pissed about, since it's the last good version of GTK+), so I have to set *that* up manually as well.~~ **[[[ EDIT: gtk2 is alive and well. I was just being and idiot and searching for `gtk2`, when the package is actually called `gtk+2`. ]]]** I installed all of the dependencies that `./configure` told me to, but I still kept getting obscure errors when running `make`. So, here's my question: what tools make the process of running abandonware easier? Docker containers? Also, what can I use to package abandonware in order to make it easy for *other* people to run? Flatpak? Appimages? Any advice is appreciated! Also, inb4 "just find a modern alternative". That would be a reasonable solution. I don't want reasonable solutions!

Context: Even though Chromium has native support for AVIF, a very nice image format, Microsoft goes out of their way to remove it from Edge, which is a chromium fork. Jpeg XL (JXL) (not to be confused with Jpeg (JPG) or Jpeg 2000 (jpg2k) ) is another nice image format, which, IIRC, is only supported in Firefox.
