    Or when you ask for feedback on the structure and what to include before you polish a bunch of stuff that would be cut or rewritten, only to be returned a half-finished low-effort style (“grammar”) nit-pick of a draft with increasingly angry comments about repeated “errors”, culminating with swearing at you, how dare you waste his time, how dare you not read his Grammar_Lesson.docx (God help you, you did) and submit a draft that doesn’t follow its rules (it was largely compliant), you’re a native English speaker anyhow and should know better, and what the fuck is compound 12a, you didn’t define it anywhere but keep referring to it (it was defined in-text in the previous paragraph and in the figure above it), fix it all and the rest of the doc before you bother him again.



  • Depends what is meant by green. Acetone is decent for health and safety (flammability notwithstanding) but is produced from petrochemicals and tied to the production of phenol (petroleum -> benzene and propane (or natural gas -> propane), propane -> propylene, benzene + propylene -> cumene, cumene + O2 -> phenol + acetone). Not much chlorophyll involved. Also has somewhere between a moderate to obscene CO2 burden depending on how you draw that box in and around the oil industry, but so do most commodity chemicals.

    I for one haven’t used heavy metal catalysts in a year

    Maybe not directly, but a lot of commodity chemicals rely on some truly vile metal mixtures for catalysis :)

    Aqua regia ain’t no piranha, and also ain’t the most concerning thing in my post lol.

    Ah bromime. Super dense, low MW, and low bp, all making dosing accurate amounts a heroic feat. If you store your bromine cold, you can precool the pipette by sucking up and spitting out a few times before transfering, which helps cut down the vapor.

    That’s just bad management / just put it on high vacuum

    Yes. The whole thing is satirizing the “Safety -> Against” bit. Each piece, though exaggerated for effect, has a basis in something I’ve seen over the years.

    Regarding NMR tubes though, the answer in my old group was precious metal complexes, which have a tendency to mirror out once they’ve done their bit. Or just existed for too long; a lot of them were touchy. The mirror tends to resist solvents and scrubbing. Nitric acid alone sometimes was enough to remove it depending on the metal, but often not. At some point the cost, effort, and danger are all supposed to outweigh just binning the lot and buying new tubes, but my PI was allergic to buying new things.

    Like, so what if we store our tBuLi with other low-flash point flammables? And pyrophoric oxidizers? In the same bin? That’s stuck in a block of ice in the 30-year-old freezer because it hasn’t ever been de-iced?

    What if the power goes out for a long period of time and the tBuLi goes for a swim? Or we say you have to de-ice the freezer?

    Haha sounds crazy. And, I wouldn’t have to do the shitty quench before disposal. Or work on that project anymore.

    Because you’re injured or because PI fires you?

    Haha, yeah :)

    Oh, while you’re here, does this still smell like DCM? I can’t tell if I rotavapped it all off and the NMR tubes all need aqua regia (sorry my b).




  • I don’t use gVim, but for work stuff that I don’t have to share (mosly just notes), I use markdown in Obsidian w/ vi mode :) It’s not FOSS and Electron is bloat, but it is really slick, and my boss approved expensing the $50 seat license for business. I might check out logseq in the future, but Obsidian was a lot more mature back when I was looking around. My only beef is that Markdown doesn’t natively support sub/superscripts, which are kinda important for chemistry. Most editors implement extensions, but they’re not always portable.


  • Do you have an alternative to suggest?

    For the general user? Not really, I’m just venting :) I have the unsubstantiated, possibly irrational belief that MSO UX ought to be far more polished after having existed for so long. Like you said, most of my frustrations have workarounds, even if they are buried or tedious (though the tedium is part of my contention).

    For making slides or posters, someone in school recommended to lay out a poster or each slide completely in ChemDraw (basically a specialized, widely used vector-based WYSIWYG editor for organic chemistry) and paste the lot onto a PPT slide. That works reasonably well and makes everything have a consistent look, especially since most slides of mine contain chemdraws of molecules anyway. ChemDraw does have its own warts and somewhat limited functionality beyond drawing molecules and text. Also, since like 2019 the rendering and UI have gotten so much slower. For posters and basic diagraming, I currently use Inkscape, pasting things as needed. Inkscape also has its quirks, but its interface is so much more powerful and the UI so much more responsive than either ChemDraw or PPT that it is the clear winner for me. Though, it is also not winning any startup races.

    For Excel, you’re unfortunately correct; there is no suitable WYSIWYG spreadsheet replacement. While I can do essentially all of the typical numerical hacking I do in Excel with (IMO) a better experience in LibreOffice Calc, it falls down when I need to show it to someone else. The charting in Calc is lackluster, and it doesn’t play nice with Office file formats. Also, my workplace (though not me personally) makes heavy use of Excel UI + VBA + fortran (!) DLLs for reactor modeling…

    LO Writer is probably the closest to Word in usability, but compatibility with Word files is still subpar, mostly to do with styling and formatting. Both are bloated for probably 50% of my use (e.g., writing up informal procedures or meeting minutes). Wordpad (RIP) is nice in that regard.

    it used to be a direct menu item but now it is quite buried…

    My colleague swears that UI in MSO before Office 2007 was so much better, but I can’t comment much on that.


  • I mean, it’s okay… I feel like I run into inconveniences in MSO every day. Off the top of my head (solutions welcome):

    • Absurd startup times for opening documents. Worse if there isn’t an instance of the app already open. Part of the blame goes to my company’s antivirus software, but Excel and PowerPoint are easily my slowest-starting apps, and Word is the runner-up. All UI animations are also stupidly slow, though I think that was a design choice.
    • A pasted graphic goes to the center of the slide in ppt regardless of the current zoom or view. Annoying for making large posters, exacerbated by delayed rendering of lots of graphics.
    • Likewise, zooming occurs relative to slide’s center, not the current zoomed view or from the mouse pointer.
    • No easily accessibly horizontal scroll outside of using a touchpad (i.e., scrollbar only). Tilting the mouse wheel (if I even have access to such a mouse) either doesn’t work or only slightly nudges the view. Also makes posters tedious in combination with pasting issue. Something like shift+mousewheel would be nice.
    • Dragging a scroll bar does not update the view until you release it.
    • Sometimes the amount of space between a bullet point and text in a PPT text box changes when all others are remain the same. Possibly a skill issue related to styles. Still frustrating.
    • Dragging objects autoaligns them to seemingly everything except what I want it to. I now run with snapping turned off.
    • Pasting charts between documents changes to destination formatting/styling by default.
    • Pasting text from external sources keeps formatting by default. Never have I ever wanted to copy a web page’s or email’s font, color, and size into my own docs. I could have sworn that there were also circumstances where ctrl+alt+v doesn’t work properly, but I can’t seem to remember/reproduce that at the moment.
    • Dates in Excel. It’s a meme, but also true.
    • Excel seems to have a “root” window (the doc opened first), and it does not play nice with virtual desktops. If you try to open a spreadsheet from Windows Explorer or some other app (e.g. web browser) on VD B while the root window is on VD A, you are forcibly switched to VD A, where the doc actually opens (after a complimentary delay, of course). Then I have to find the freaking window in Task View and move it back to VD B. There is a reason I wasn’t adding more windows to VD A to begin with. Incidentally Word and other MSO apps do not have this issue for some reason.
    • If one doc window freezes/stops responding, they all do.
    • Aligning things in Word
    • A few common color palettes are not colorblind-friendly.
