Edit: this appears to be fixed now: https://lemmy.ml/post/22203615/14801411

All images in posts on lemmy.ml are currently being resized to 256px on the longest dimension (width/height), even if they are image posts, not intended to be just article thumbnails.

Is this an intentional change? It makes text in images illegible and means that I have to view the original post to see the original image on every image post.

If this is a deliberate space-saving measure, could it be tuned for a little better usability? For example, increasing the maximum size of image when the post is an image post (as opposed to a web link that generates a thumbnail) and setting a size threshold to trigger resize (ie. most small images could be left alone).

Some examples from my feed:

Threat actors are utilizing an attack called "Revival Hijack," where they register new PyPi projects using the names of previously deleted packages to conduct supply chain attacks.

The technique "could be used to hijack 22K existing PyPI packages and subsequently lead to hundreds of thousands of malicious package downloads," the researchers say.

If you ever install python software or libraries using pip install then you need to be aware of this. Since PyPI is allowing re-use of project names when a project is deleted, any python project that isn't being actively maintained could potentially have fallen victim to this issue, if it happened to depend on a package that was later deleted by its author.

This means installing legacy python code is no longer safe. You will need to check every single dependency manually to verify that it is safe.

Hopefully, actively maintained projects will notice if this happens to them, but it still isn't guaranteed. This makes me feel very uneasy installing software from PyPI, and it's not the first time this repository has been used for distributing malicious packages.

It feels completely insane to me that a software repository would allow re-use of names of deleted projects - there is so much that can go wrong with this, and very little reason to justify allowing it.

Description: "Featured is a playthrough of a blitz chess game between Rodrigo Vasquez and Vladimir Kramnik from an Early Titled Tuesday event which was held on October 17th, 2023. Kramnik recently admitted, via a YouTube comment on this topic of fair play surrounding him, that he played several tournaments under someone else’s chess.com account. This act violates chess.com’s Fair Play Policy. Kramnik played under Denis Khismatullin’s account, “Krakozia”. I share reasons why this is a violation of fair play policy, how a player can be negatively impacted because of it, and provide Kramnik’s YouTube comments where he attempts to explain it all."

Most people know at this point that when searching for a popular software package to download, you should be very careful to avoid clicking on any of the search ads that appear, as this has become an extremely common vector for distributing malware to unsuspecting users.

If you thought that you could identify these malicious ads by checking the URL below the ad to see if it directs to the legitimate site, think again! Malware advertisers have found a way to use Google's Ad platform to fake the URL shown with the ad to make it appear like a legitimate ad for the product when in fact, clicking the ad will redirect to an attacker controlled site serving malware.

Don't click on search ads or, even better, use an ad-blocker so that you never see them in the first place!

A reported Free Download Manager supply chain attack redirected Linux users to a malicious Debian package repository that installed information-stealing malware.

The malware used in this campaign establishes a reverse shell to a C2 server and installs a Bash stealer that collects user data and account credentials.

Kaspersky discovered the potential supply chain compromise case while investigating suspicious domains, finding that the campaign has been underway for over three years.

[SOLVED]: The issue was caused by having "Show read posts" unticked in Settings. This will hide your own posts from you!

I recently made a post^[1]^ to this community about a bug that I experienced and reported.

The post does not appear in the New feed for /c/lemmy_support nor does it appear in my user profile under Posts ^[2]^.

However the post does have 3 replies (from users on multiple different instances) which means that other users can see it across the fediverse, so it's not a federation issue. (Also, my account and the community are both hosted on the same instance - lemmy.ml).

I was not subscribed to /c/lemmy_support at the time I made that post, but I am subscribed now to see if that affects my visibility of this post.

Is this a bug, or am I misunderstanding how lemmy works?

Interestingly, if I view my profile while logged out, it does show the posts that I made, but when logged in it shows zero posts in my profile.
