Yeah, this is what I am seeing with https://ollama.com/library/deepseek-r1:32b:

Running ollama and witsy. Quite confused why others are getting different results.

Edit: I tried again on Linux and I am getting the censored response. The Windows version does not have this issue. I am now even more confused.

Interesting, if you tell the model:

"You are an AI assistant designed to assist users by providing accurate information, answering questions, and offering helpful suggestions. Your main objectives are to understand the user's needs, communicate clearly, and provide responses that are informative, concise, and relevant."

You can actually bypass the censorship. Or by just using Witsy, I do not understand what is different there.

The censorship described in the article must be in the front-end. I just tried both the 32b (based on qwen 2.5) and 70b (based on llama 3.3) running locally and asked "What happened at tianamen square". Both answered in detail about the event.

The models themselves seem very good based on other questions / tests I've run.

This is a great collection, thank you. :)

Compiler engineers like fuzz testing. You'll find a bunch of infra for it in llvm. That should mean the easy targets have already been hit, though I wouldn't be too confident of that stance.

Plus there are hordes of academics using Clang/GCC as targets for bug-finding papers. The Csmith [1] paper alone has over a thousand citations at this point. I'd assume most of the low-hanging fruits are picked.

It's pretty easy to remove them by adding one line to the recipe and re-fetching:

Great, thanks!

Someone linked to a Calibre recipe that assembles everything into one ebook. Here is the result if anyone else needs it:

Thanks. It looks like this includes comments which blows up the page count dramatically. A little unfortunate.

Can I ask what you mean with "pretty common"? Do you think more than half of all STEM graduate students had a similar experience as she did? Do you have actual data to support this?

I am asking this because HN neems to be so much more negative of academia than what I am seeing around me.

More generally I think it is worth stressing that any site like this can be a terrible echo chamber at times. Generally there are smart people here, but on some topics I suspect that the consensus could be completely misguided.

> Do you think more than half of all STEM graduate students had a similar experience as she did? Do you have actual data to support this?

Yes, her entire description about her experience (safe for that weirdness with the textbook sweatshop) is relatable. I am not sure what you are looking for but STEM PhD attrition rates speak for themselves. Those do not include PhDs that decide to leave academia after retrieving their PhD. Not to mention the frequently discussed mental health crisis that consistently gets Nature articles.

HN's negativity is comparable to the negativity I have seen with CS, Maths, and Physics PhDs and Postdocs in personal discussions. See also PhD comics: https://phdcomics.com/comics/archive/phd072011s.gif

If you are an idealist you will of course be worn down by the way many academic institutions are set up. There is a ton of writing on this, e.g., https://www-users.cse.umn.edu/~odlyzko/doc/decline.txt

Not to highjack this topic, but she was recommended (like to many others of you no doubt) quite a bit in my Youtube feeds over the last few months; and the first few videos I watched seemed to be solid enough. Yet as I watched a few more, I couldn't shake the feeling that she's so out of left field that she's not just a 'quirky renegade' anymore, but rather a quack who dresses up her quackery with just enough 'real' physics to make it all sound very convincing. (By that I don't mean that she says factually wrong things, but that her conclusions or extrapolations from established facts seem to me, well, outrageous). However, I don't know enough physics to be able to tell if this is a correct feeling, and the Youtube comments are, as usual, one big fanboy fest, which is true for any large enough channel - even those of flat earthers and similarly delusional content).

So my question is - just how serious should she (and others like her, who denounce 'mainstream' academia as much as those other fringe groups who go on and on about the corruption of 'mainstream' media) be taken? Anyone have an opinion on this?

I know nothing about her but the video on her experience in academia is spot on. It's a pretty common experience among STEM academics. You will face the point where you have to compromise your academic "purity" and curiosity for trendy topics to survive. This also implies publishing "bullshit" papers and "bullshit" grants. Only certain types of people make it through that.

Condé Nast is where awesome goes to die.

They seem to be doing okay with the New Yorker, although I do not know how the magazine was viewed before their acquisition.

Sometimes they don't even bother to sell it. In the case of Barefoot Networks, they bought it, spent three years developing the next-generation product, got it to within 80-90% of being ready for tapeout, and then just pulled the plug.

fruffy · 2 years ago

The customer reaction to this decision spoke volumes. The official reason given is margins compared to hardware such as the IPU but, personally, I chalk it up to turf wars. Barefoot had a distinct culture to Intel's other networking units. There is a reason many of its engineers ended up at FAANGs and not other semiconductor companies.
