I pitched this exact idea to my fiancé a few days ago (and have no clue why it came up). she didn’t think it was a good idea, but now I can tell her that it was good enough to patent.

I am half way done with mine, which means I only have 3/4 left to write, then I will be 90% done.

My boss read the first chapter I turned in, decided I know what I am doing, gave me some basic feedback, and has completely checked out since then lol.

My pocket DAC/Amplifier Combo, works over Bluetooth and wired, built in mic. Allows me to both have great audio quality for music over wired and use my favorite IEMs wirelessly when sound quality isn’t my first concern (biking, working in my lab, chores, etc). I used to just use my wired DAC for listening to my phone, but having the flexibility of choice makes life so nice.

I just wish they had used a better battery, I have had to send it in multiple times for battery swelling.

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 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).

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.

When I was a kid, it was playing card rubberbanded to my chainstay so I could pretend I was riding a motorcycle from the noise

Nowadays, I prefer to just let out wolf whistle. Pierces even the best noise cancelling headphones and busiest traffic noise.

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
