Love Zotero, have been using it since I started out as a researcher. I've found the PDF view to have noticeably more lag than either preview or skim, but I can live with that for entire package (and can just open the papers in those readers).

What has been causing you stress? (If you don’t mind me asking?)
trostaft · 2 months ago
It's nothing special. I'm an academic and usually I balance my desire to work / deadlines and family obligations. The last month I screwed up my management and got frustrated at both. I was holding that emotion even after crunch-time had passed.

Sometimes a lighthearted piece is all you need to remember to release. What's the saying? "The sea of bitterness is vast. Turn back, and you may yet see shore." I still love what I do, even if it got tougher than expected for a moment.

What a wonderful article. My stress has been drowning my joy in something I once found fulfilling. While reading this, I suddenly remembered it. Thank you.

> If the mere sight of the above is like a punch in the face for you, don't worry. I'm not going to math you to death in what follows. I will only remind you of a tiny basic part of it that I think relates to languages.

Yes, that mathematical expression is like a punch in my face, but not for the reason you think. I am offended that the rank of the matrix does not match the dimension of the matrix, not that I'm seeing a matrix.

You probably mean that the size of the matrix is incompatible with the size of the vector?

What are review papers for anyway? I think they are either for

1) new grad students to end up with something nice to publish after reviewing the literature or,

2) older professors to write a big overview of everything that happened in their field as sort of a “bible” that can get you up to speed

The former is useful as a social construct; I mean, hey, new grad students, don’t skimp on your literature review. Finding out a couple years in that folks had already done something sorta similar to my work was absolutely gut-wrenching.

For the latter, I don’t think LLMs are quite ready to replace the personal experiences of a late-career professor, right?

I've found (good) review papers invaluable as an academic. They're really useful as a fast ladder to getting up to speed in a new area. Usually they have a great literature review (with the important papers to read afterward), a curated list of results important to understand, and good intuition about how to reason. It's a compactification of what I would have to otherwise gain by working in an area for years. No replacement for it, of course, but does make it easier attain.

I don't understand the appeal of an (majorly-)LLM generated review paper. A good review paper is a hard task to write well, and frankly the only good ones I've read have come from authors who are at apex of their field (and are, in particular, strong writers). The 'lossy search' of an LLM is probably an outstanding tool for _refining_ a review paper, but for fully generating it? At least not with current LLMs.

I've made a test for myself. Screen split into two parts, two small squares moving and bouncing. First square moves every frame, second square skips every second frame, but moves 2x. So basically one half of the screen is full FPS, another half of the screen is half FPS. And I implemented it as a "blind test", so I could make a guess and then check it.

For screen with 60 FPS, the difference between 30 FPS and 60 FPS was pretty obvious and I could guess it 100% of the time.

For screen with 144FPS, the difference between 72FPS and 144FPS was not obvious at all and I couldn't reliably guess it at all. I also checked it with a few other persons, and they all failed this simple test.

So now I'm holding firm opinion, that these high-FPS displays are marketing gimmick.

https://pastebin.com/raw/hwR62Yhi here's HTML, save it and open. left click reveals which half is "fast" (full FPS) or "slow" (half FPS), scroll changes speed, F5 generates new test.

Pretty cool test, but I wonder how fast you ran them at? I was able to distinguish between full and half after increasing the speed to around ~2000 units.

> I'm sure I could learn to be slightly faster on dvorak/colemak, but nothing beats the convenience of always having guaranteed access to qwerty, everywhere I go.

Colemak/Dvorak is not about speed, but about comfort and avoiding RSI (though I would place the actual layout somewhere far down on the list, a proper ergonomic KB is top priority). Also, in my ~8 years on Colemak lack of access to it was a problem exactly 0 times. I don't type books on other people's computers, and if I would, typing blind on a keyboard I am not used to is anyway a hopeless endeavor.

Do you have any opinions on ergoKB? I've begun to notice some pain, not in my wrists, but in my upper forearms and am thinking about something to fix that.

I cannot for the life of me understand the Omarchy hype. The Linux community has been theming their distribution installs for decades. What distinguishes this from that?
trostaft · 5 months ago
I don't think it's that crazy. Hyprland has, for a long time, looked really lovely when configured. But most don't want to configure it, the linux ricing community is really small in proportion to even the people who want to install Linux. Omarchy is dead-simple to install, has good documentation, decent opinions[1], and has huge influence because of DHH himself. I stopped running it myself after while, in favor of configuring my own Hyprland install, but it's an easily accessible shiny new thing by someone with a big following. Seems reasonable to me that people like it.

[1]: I don't agree with all of them, e.g. the chatbot shortcuts. But they're trivial to disable and/or redirect and, indeed, the project does a good job of trying not to mess with your changes.
