I imagine they don’t want the possibility of the researcher just getting a new academic email and continuing to do it. Also, it forces the university to react since the researcher clearly isn’t willing to stop judging by their responses.



Discord themselves have a pretty bad privacy track record AFAIK. Obviously not a raging dumpster fire like Microsoft, but still.




The first rule of pentesting is to get goddamn permission before you exploit something. Come to think of it, what they did is probably federally illegal under computer abuse law.


If they don’t force the users to share their personal information, scrapping would not be the big problem they face now.

Clearly they don’t give a shit so…




Does the heat-sink get very hot as well when you run it like that?

Actually, not really. It gets hot to the touch, but it certainly doesn’t feel like “it’s cooling a 120 C chip” hot. I can keep my finger on it for quite a while before it gets painful.

but the RAM chips are over-heating

The RAM is on top of the chip, so I assume it’s cooled by the heatsink too.


Anyone else been burned by getting the /dev/sdX letter wrong?

I’m getting into single board computers, and I’ve overwritten my external hard drive twice now trying to flash OS images to SD cards using dd (good thing my important data is backed up). To be fair, it’s totally my fault, but I’m curious if anyone else has done this…


I use CherryTree and Xournal++ on desktop, and Scarlet Notes on Android. All of them are open source.


Ah yes, the classic victim blaming line: “you should have defended yourself better if you didn’t want me to attack you”


Armbian SBC locks up after a while under heavy all-core CPU load

I have an Odroid HC2 with an Exynos 5422 8-core processor running Armbian Buster. When I perform a computational task that loads all the cores to close to 100% (in my case, pigz, which is a multithreaded gzip), the entire system locks up after a fairly short while, to the point where it won’t even r…



Btrfs performing poorly on random access operations?

I suspected that btrfs partitions are kind of sluggish compared to ext4 when performing many small operations, so I benchmarked three separate partitions on the same hard drive, one ext4, one btrfs, and I threw in NTFS for good measure. This was done on a hard drive which was formatted between tests…


What are some good USB Wi-Fi adapters are natively supported by the Linux kernel?

I have single board computers running Armbian, and so far I’ve just been communicating with them over UART, but obviously I need network connectivity for them. Are there any USB Wi-Fi adapters that are natively supported by the Linux kernel without needing to download something first? I really pre…


I got some concerns with the “fake news” part of this post. Let me just clarify what I meant by “blatantly fake news”. Personally, I’ll only remove things that are without a doubt false, and maliciously so, things like “Trump won the 2020 election”, “Climate change isn’t real” or “Vaccines cause autism”. Or, from “news” sites that have been proven to be puppets of organizations like the CIA. Stuff that “might be wrong” is generally left to up/down votes.

Though keep in mind that I’m talking about removing things at the site level with this, moderators of individual communities are generally free to remove stuff the admins don’t have a problem with at their own discretion.

I block mousemove, touchmove and scroll, and other events which are basically these but with a different name.


Regarding blogspam
pin

In the recent months, we’ve been getting more blogspam accounts, and the administrators have been discussing behind the scenes on how to deal with it. Blogspam is against the rules of this Lemmy instance and is treated the same as any other spam. That is, offending posts will be removed and blogspam…


Plenty of great suggestions already, and I echo most of them, but I’m going to add two that I haven’t see mentioned:

  • Luminous for blocking specific JavaScript events and event handlers (I use it mainly for reducing the effectiveness of session recording).

  • uMatrix for blocking site (anti)features such as scripts, cookies, media, XHR, etc on a per-domain per-site basis. IMO it provides the most granular control among all the similar blockers.

Sadly, it seems they’re both no longer being developed, but they still work fine for the time being. I’ve also been thinking of picking up the Luminous codebase in the future.


however really disliked that pretty much all TVs today are Smart TVs

I think you should be fine if you never connect it to the internet. We’re not at the stage where TVs have their own independent data connection (yet).

Though you can still get dumb consumer TVs if you look hard enough, but I agree that they’re becoming rarer.


I definitely would, but again, I don’t own the TV nor do I normally watch it (I mostly watch videos on my Degoogled Android phone or Linux PC).



Smart TV suddenly stopped looking up tracking domains. Is this bad?

I have a Samsung smart TV that is configured to use my Pihole instance as its DNS. When it was first set up, it looked up a blocked Samsung domain every few seconds whenever it was on (this is with ACR tracking “disabled” in the settings). Now it doesn’t anymore, but I still get activity from its IP…


Yeah, I think a benefit of compute modules in today’s tech environment is that it’s self contained and can be made for extremely backward and forward compatibility and let you use whatever compute hardware you want, especially one of the open source standards out there.

(copied here from another one of my replies)


Anyone who denies it at this point is either living under a rock or has ulterior motives.


For a hypothetical modular laptop, would you prefer one based around an integrated system-on-module or everything separate?

Modular laptops are few and far between, but the concepts and in-market products that I have seen seem to fall into two general categories: ones that are based around a removable system on module with the CPU and RAM soldered, and ones that are all-out discrete for everything, including socketed CPU…



What are some good themes for making Qt and GTK apps look consistent with each other?

I use KDE Plasma, which is great, but it always bothers me on the default themes, most third party apps have a different design language compared to the desktop and system apps due to them being GTK and Plasma being Qt. Are there any good themes that can be installed for both Qt and GTK and make the…


What do you think of USB C as a charging connector compared to a magnetic charging connector?

My first laptop was a Surface, so was my second, both having the magnetic Surface Connect port. Recently though, I bought a new Lenovo Thinkpad, which charges via USB C. My first thoughts were that the USB C was a lot less convenient. With a magnetic connector, I could just wave the cable at the por…




How do you deal with the non-static IP when hosting something from home?

I have a few single board computers at home that I want to try hosting some public facing stuff with, but what’s the best way to deal with the fact that my home internet is not on a static IP? Would I have to host my site from a DynDNS domain and hope that when the IP changes, the DNS caches of user…


Are there any light projects I can run on a Raspberry Pi Zero?

I have a Raspberry Pi Zero W that is serving as my Pihole server, but that only uses about 10% of its very underpowered CPU, and I feel like I’m not getting my money’s worth. Anyone have any lightweight project ideas I can run on it to use up more of its resources? …
