As I understood it’s enough to have “access to run privileged application” anywhere where the packet goes through. So, not necessarily at client or server sides. Or did I misunderstand?

I think he's referring to CPU mitigations: https://en.wikipedia.org/wiki/Transient_execution_CPU_vulner...

That sycophancy has recently come roaring back for me with GPT-5. In many ways it's worse because it's stating factual assertions that play to the ego (eg "you're thinking about this exactly like an engineer would") rather than mere social ingratiation. I do need to seriously try out other models, but if I had that kind of extra time to play around I'd probably be leaning on "AI" less to begin with.

Ok, but if I run (say) HTTPS over the innermost tunnel, then I suppose that HTTPS will take care of any discrepancies.

The malleability of the ciphertext matters because it enables certain circuit tagging attacks as the article explains. It means that the exit relay could confirm you are using a guard relay also controlled by them and thus discover your origin IP address.

There are many reasons that these cryptographic tagging attacks are a lot worse than just the timing correlation attacks that are possible if you control the guard and exit of a client: https://archive.torproject.org/websites/lists.torproject.org...

Nice article and especially so for including the parsing that most people just outsource. What's great about using an emulator is that you can also do fun things with the syscalls like implementing your own "virtual filesystem" instead of just translating directly to the x86_64 equivalent syscall: https://github.com/gamozolabs/fuzz_with_emus/blob/master/src... (not my code but basically something like this)

Two bugs to know about. First, you are using a deprecated API call that fails in Firefox. Second, you are using an HTTP endpoint that fails to upgrade to HTTPS to call the GoodReads API, which also fails with HTTPS-Only enabled in both Chrome and Firefox.

The idea seems good, but since I can't import my GoodReads successfully, it's hard for me to try

OK, I think the problem was that you are only supposed to input the user ID number. I just limited the form to numbers only and updated the description to make this more clear.

I tried to import my book list with "Import goodreads" button and inputting https://www.goodreads.com/user/show/68515148-andrew but it said "import failed, see console"

Hi, I just realized that the confusion here was that you are only supposed to input the numeric user ID. I just limited the form to numbers only and updated the description to make this more clear.

Ah. My fault. I put the whole URL in the User ID box instead of just the User ID.

Do you know how your model compares to Cinematch's SVD? Does your model use only books rated highly or also include low rated ones?

costco · 3 months ago

I am not familiar with Cinematch, is there a writeup about it? When training I used every input book and did not include ratings as a feature. In the future I want to experiment with treating 1 or 2 star ratings as negative feedback.

Import doesn't work for me.

costco · 3 months ago

Can you access your profile page in incognito (ie is your account public)? Alternatively, if you have more than 5000 books in your shelf, that might break it. I just tried a number of users and I was able to import them all.

I would love to be able to filter the resulting list by removing certainly all books that in the same series but I think removing all books by authors that I have already listed would be great to get new things that I haven't already read. The resulting recommendations maybe included 1 new book for me.

costco · 3 months ago

I did not add what you requested exactly because I think in many cases authors have written less popular books that people may not be aware of but if you try again you should see less highly repetitive things like 5 of the same series in a row in the results.
