    My goal for the summer was to finish my PhD. I defended on Friday and am now Dr. Drail, so I actually accomplished my summer task for once. I sacrificed all my sleep and sanity to do so, as I was told at the 11th hour to redo a major analysis that made up 1/4 of my dissertation, but I fucking got it done.




  • I am a physicist. I am good at math, okay at programming, and not the best at using programming to accomplish the math. Using AI to help turn the math in my brain into functional code is a godsend in terms of speed, as it will usually save me a ton of time even if the code it returns isn’t 100% correct on the first attempt. I can usually take it the rest of the way after the basis is created. It is also great when used to check spelling/punctuation/grammar (so using it like the glorified spellcheck it is) and formatting markup languages like LaTeX.

    I just wish everyone would use it to make their lives easier, not make other people’s lives harder, which seems to be the way it is heading.



  • Former chain of vegan subs out of SoCal named Subvegan had some of the best sandwhiches I have ever tasted, vegan or otherwise. Vegan deli meat and vegan cheese quality vary, but this place had the hookup for the best of both. A 9in sub was $12, loaded so fat it barely closed and was two meals worth for any normal person.

    Their italian sub, the Godfather, had (vegan) turkey, ham, salami, provalone, cheddar, pepperoncini peppers, tomato, arugula, olives, onions, mayo, and italian dressing. The bread was always the perfect ratio of crunch to fluffy, their sauce portion was always on point, and their veggies were fresh as fuck. I salivate even just typing it out.

    My fiancee and I would order in advance to have a sub waiting for us whenever we visited her family in Anaheim. It was the best. We started making plans in June to move out there so she could live near her parents and they closed their doors in July. Good vegan subs are a rarity, let alone vegan subs that stand out in quality against their non-veg counterparts. I am still in mourning.

    Not to dunk on word, if I need slightly more flexibility than a native .txt reader, it will do in a pinch. That being said:

    Word: Oh, you want a table? Good luck getting your excel sheet to cary everything over properly, and god forbid you change a formula. You want to write it natively in word? Lol no.

    Latex: tabularx goes brrrr


    Word: Equations? Have fun properly tracking equation numbers and manually formatting your text to center justified every time.

    Latex: $ $, \( \), and \begin{equation} go brrrr.


    Word: Figures? Hope you anchored everything properly, it would be a shame if your entire document layout got shifted…

    Latex: What the fuck is an anchor? top, here, bottom, those are your options. Add an exclamation mark if you’re feeling spicy.



  • I did all my Quantum Field Theory homework in Latex, the professor required it. My classmates would write everything out by hand and then transcribe it, meanwhile my officemate and I could think/write/math in Latex, so we only had to write our homework once. The prof lifted the requirement halfway through the semester after everyone else complained, but I never looked back.

    The only thing that prevented a 100% Latex-only semester was the goddam section where we had to draw Wick diagrams. There just wasn’t a reliable way to draw them on my computer, as the Feynman diagram tools stuggled with the nuances of Wick diagrams. I still included the hand-drawn versions as figures in Latex, but it felt like cheating.

    I did figure out how to write the Wick’s theorem bracket notation in Latex though (not that I’ll ever need to again), so that made up for it a bit. I wager that I spent more time researching obscure Latex packages than actually solving the problems that semester.

    I love Latex so much, I even made a template for generating profesional looking DND item cards for my table that I submitted to overleaf: https://www.overleaf.com/latex/templates/d-and-d-item-card-template/ndfdspmmxnrn


  • I had a bad flea infestation after taking in a stray puppy for all of 1 day before I got it to a rescue. I went from noticing one flea to noticing a couple to seeing them everywhere in a manner of days, about a month after the puppy left us our present. It was a pain in the ass and made me hyper paranoid, so I learned how to handle it the proper way.

    I agree with what others have said as a first step: Flea Bath and/or nitenpyram to remove the fleas on the kitty, flea preventative to keep them off. Wash all the fabrics and surfaces, especially near your cat’s hangout spots, and dry on high heat.

    Vacuuming daily is a triple threat at reducing the numbers: Sucks up the eggs/larvare/pupae/adults, the vibration and warmth tricks pupae to emerge (they can be dormant for up to 6 months and their shell acts like velcro, making them hard to remove) which speeds up the cycle and reduces the risk of reinfestation, and cleans up the grime that the larvae feed on before pupating. Just make sure you use a bagged vacuum or seal the vacuum waste somehow before tossing it. If the infestation is minor, keeping up to date on the preventative and regular vacuuming should be enough.

    If you find more, especially down the road a few months, it probably means an infestation started under your nose. If you can afford it, a pest control pro is the best solution. If you can’t, the best flea killer spray for whole home infestations is Precor 2625. It is a whole home premise spray that kills the fleas at all stages, both on contact and by disrupting their reproductive cycle. You’ll want to either kennel your kitty for a day to apply it, as the contact kill chemical can make cats sick, or at the very least quarantine them and do the spray over a couple days away from them. Get a coverall suit, N95 mask, and spray all low surfaces, all fabrics that can’t be dried on high heat, under couch cushions, all corners and crevices around the floor and your bed, literally everywhere below knee height and anywhere your cat might like to climb or hide.

    The preventative is supposed to last 7 months, slightly longer than the longest normal pupae duration, so that multiple flea generations will be affected. I do recommend a second spray 1 month later, just to be safe, and continue daily vacuuming over the entire premise for at least that first month to expedite the lifecycle as much as possible.


  • I use Tidal for listening to music on my phone most of the time, whether wired or wireless. That, plus USB Audio Player Pro for wired listening, gives a pretty good sound quality over my DAC. At home and in my work office I have dedicated DACs and tube amps for driving my cans (Schitt Modi + Littleblack Mk.2 in my office, Schitt Mobius + Feliks Echo 2 at home).

    I use the dedicated DAC on mobile for a few reasons:

    1. My phone doesn’t have a headphone jack and I have been dissapointed by most USBC-to-3.5mm dongles’ build quality, so using a higher quality DAC gets around that.

    2. I also generally prefer a balanced 4.4mm jack over an unbalanced 3.5mm, both for a more solid physical connection and to reduce crosstalk, and my DAC has both 3.5/4.4mm ports.

    3. For wireless. I use IEMs that have a wired connection and the bluetooth adapters/replacement cables are pretty low quality in my experience (low battery capacity, poor sound quality, poor build quality, finnicky connectors, etc.) and a combo bluetooth/wired dac is avoids most of these issues. It also means I can keep the DAC and my phone in different places on my person (great for having my phone on a stand while biking and keeping the DAC in my pocket, or leaving my phone charging while I listen to music in my lab).


  • No, the Ifi GoBlu. Great sound quality, great aesthetic, convenient size, garbage battery quality. I have had to send it in 3 times for swelling. Each time, I have buckled down more on making sure I was more careful with charging; using a smart charging or low power USBC AC adapter, then using only low voltage adapters, finally demanding they send me an AC adapter designed for it since they didn’t include one.

    Such a significant thing to cheap out on with a $200 piece of tech, especially when LiPo batteries are already so cheap. They also refused to send spare batteries as well this last time, which I am more than capable of replacing myself, to save ~3 weeks of time. I have decided that if it happens again, I will just find a comparable size/voltage battery and solder it in myself to spare myself the hassle.




  • I work on a 0nuBB search doing detector R&D, this is spot on, but has 2 extra components. The three elements needed for explaining the asymmetry are:

    1. CP Violation
    2. Lepton or Baryon Number violation
    3. Interactions out of thermal equilibrium

    These are the Sakharov conditions for Baryogenesis/Leptogenesis. #1 has been observed via the weak interaction but not in large enough quantities and is not observed via strong interactions, #2 is what proton decay and 0nuBB searches look for, and #3 can be, at least partially, explained by the expansion of the universe as a non-equilibrium interaction.

    To get from leptogenesis to baryogenesis requires theretical physics I only barely understand using particles call sphaelerons that convert leptons to baryons.




  • Fighter as a class is only as cliché as the story behind it from an RP perspective imo. An assassin who has only relied on his mental acuity (precision and brain blades) and stealth to reach their goals deciding that they need to more formally learn how to be an effective combatant doesn’t read as cliché to me, it seems very pragmatic. Or having escaped near death time and time again in combat, an assassin learning by trial and error how to improve their odds of surviving direct combat. Or literally extracting the knowledge via their soulknife abilities from every fighter they slay, adding experiences into their repertoire. Loads of potential there for a fun Rogue/Fighter build.

    I have three questions that I ask every time I theorycraft an MC build (and some example prompts):

    1. Why do you want to MC? Is it to make a more powerful character/to diversify your skills/to fill a niche in the party/for narrative completeness/etc?

    **2. Why is your character developing these new skills? ** Does your character have a latent predisposition to this change? Did they get challenged in a way that necessitated change? Did a party member/mentor influence them to try out a new skillset?

    3. Do you want the change to alter your concept for the character (both in combat and RP), and how does that fit with the character you play?

    Answering these questions helps me a lot in deciding how to explain the MC decision, flesh out the character concept, and work it in to the game as written. If you just want to mix it up or beef up your character, that is fine too, but I think it is more satisfying when you can bridge the RP and the mechanics.



  • My two cents is that multiclassing should be driven first and foremost by what seems cool or fun, then looking at story consideration, and finally looking at optimization. Rogue is one of the best classes for MC, it has endless synergy with basically every other class, so I don’t think there is a wrong answer in terms of viability. Rogue/bard is super fun, allowing for a super versatile character in terms of being the face and skillmonkey, rogue/fighter is a potent martial combination, and warlock rogue has neat RP potential and some nice interplay between invocations and roguish abilities (darkness, mask of many faces, etc.)

    How has you character been played so far? A dashing trickster would lend itself to bard (swords, whisper, or lore), a deadly and efficient assasssin would lend itself to fighter (BM or echo knight if allowed), or a curious seeker of secrets would lend itself to warlock (hex blade is the best choice for a mixed martial imo).
