  • How long has it been curing and how off was the mixture?

    Way too little hardener = will remain tacky

    Somewhat too little hardener = will cure, just more slowly

    Too much hardener = will cure quickly

    The specifics come down to the expoy in question and whether or not the maker pads their ratio one way or the other to make it easier to use.

    If you’re only somewhat off, I would give it time and you’ll probably be OK. If you’re way off, I would still give it time but would be less hopeful.



  • Qualcomm’s stuff is within single-digit percentage points of the current-gen AMD and Intel chips both in power usage, performance, and battery life

    Back in June, the new Snapdragon X processors were a lot more efficient than their x86 based counterparts. I can personally attest to much lower levels of heat generation.

    The problem is that the current tradeoff is that huge amounts of the software you’ve been using just does not work, and a huge portion of it might NEVER work, because nobody is going to invest time in making it behave.

    I agree with the sentiment, but IMO this is a PC and Windows problem. I would also extend this beyond pure comparability. I say this for a few reasons

    • I lose about 5% charge/day with my laptop asleep. It does wake up very quickly, but 5%/day feels like a lot. At this point, I don’t think Microsoft has a strong incentive to really optimize the kernal for efficiency
    • Historic massive variability in hardware across devices also makes it hard to optimize efficiency, although the current crop of snapdragon x laptops seem to have less variability
    • One of the strengths of windows is that it can run applications written 20+ years ago fairly reliably. There’s a ton of software that’s still floating around that hasn’t been actively supported in years. I don’t see all of these software companies desiring to port their code over, especially without guarantees that the market will adopt ARM (the Apple approach) or until they see the ARM adoption rate go up (the current Windows approach)

    All that said, I’ve had zero issues with emulation so far. I never personally used a M1 max when they launched, but from reports of that era the current Windows experience is at least as good as that.


  • I own a Lenovo Yoga slim 7x Gen 9, which is powered by a Snapdragon X. It certainly checks the “good enough” box. I use it primarily for photo culling/editing (I’m a holdout dedicated camera user). It is more than fit for purpose there, stays cool, is slim, and although I know the fan has come on a few times I wouldn’t have known if it wasn’t on my lap. When I bought mine, it was also one of the better deals - you could upgrade to 32 GB of memory and a SSD for under $125 in total. The SSD also isn’t soldered, but the memory is. The 3k OLED display is amazing, but if you want the ultimate battery sipper it’s probably not the best choice. I still get tons of runtime per charge, but am somewhat sad that I lose about 5% charge per day thanks to the laptop not really being off while asleep.

    The biggest downside is linxu support is very hit and miss depending on the laptop in question, which means you’re tied to windows 11. I don’t have the time to tinker with it, so I haven’t looked much further into it than this.







  • lol. Amusingly, my wife’s Dell Latitude 7400 with an i3 has much better stand by battery life than my 7x slim. The slim does wake up a ton faster - by the time the lid is open it’s already doing facial unlock and it it sees me it unlocks immediately and is “fully awake”, but I suspect this is achieved at the expense of more battery consumption while sleeping.

    The 7x slim loses around 5% / day when asleep :(


  • Recall was the headline feature for Copilot+ PCs.

    When a wave of ARM powered Windows laptops, and now a few desktops launched, they were all Copilot+ for whatever reason. They all marketed the NPU, but struggled to really say what the NPU unlocked that you couldn’t do with a CPU or GPU. Other marketing gimmicks were a better background blur and an AI drawing assistant in I think paint. I think you could also do “AI stuff” in photos, but don’t think that was local.

    Honestly, I think everyone missed the punchline on ARM. The promise is lower heat and greater battery life. There was no need to bundle that with AI gimmicks. But clearly a PM thought so and now they’re trying to save face. Really taking advantage of ARM and pushing for battery life, by optimizing the kernal and changing what happens in standby, would probably be a bigger engineering lift.

    /Thoughts from a rando who bought an ARM powered Windows laptop and generally likes it but has never touched the NPU enabled stuff






  • As a parent of younger kids, we’re sorry. We come armed with as many activities as possible and will take our kids outside if they’re too excited until food gets to the table. That will help them focus on eating.

    We very rarely went out to eat when they were toddlers due to fear of our kids bothering others and understand that our desire to experience some level of normalcy shouldn’t come at the expense of others.

    All that said, if the parents are trying to keep their kids occupied, please extend some grace. Being a parent can be extremely isolating and we’re simply trying to pretend like we still get to do normal things once in a while.


  • Yes. I epoxy filled some voids in a wood top for a desk I made a few years back. I used frog tape (fancy masking tape) on the bottom and it worked fairly well. Some epoxy still escaped and some of the tape was a bit difficult to get off. Be sure you do this over something like waxed paper for easier cleanup.

    Like you, I tinted my epoxy black.

    I used disposable cups for measuring, measured by weight on a digital scale (don’t forget to weigh an empty cup), and mixed with a popsicle stick. Pour on the top around the cracks. Don’t go too nuts on the first pour and let it fully cure. It will work its way into the cracks if you’re using a crack filler - that stuff is very thin. Why not go big on the first pour? It will minimize the mount of leakage you get on the backside.

    I sanded the top down afterwards and finished as per usual. The fill is very low key, which is what I wanted.
