  • One of the risks is the fuel getting jammed. Since they’re spheres, they should have very low friction. But they already saw that defects in the coating can raise that risk. They would need very strict QC on manufacturing the pellets, and the entire system must be designed to mitigate the chance of wear causing damage. There would naturally be a buildup of debris over time, but fine carbon dust usually serves as a lubricant anyway. They would need to prevent contaminants entering the core.

    Even if there was a jam, is there a foolproof way to stop the input, even during a power failure? Can the pellets sit in the reactor forever without getting too hot when the cooling is down?

    Is any of this human controlled? Part of Chernobyl was someone ignoring a failure and choosing not to shut down until it was too late - is that a possibility here?

    So yeah, saying failure is impossible is literally what they said with the Chernobyl-style reactors when they were new. They did safety tests on those to see what would happen if the power failed, which was itself the catalyst for the failure. Just say that you have a new, extremely safe design, be open about how it works, and don’t tempt fate?









  • Core Odoo pros: Odoo is great at what it does. It’s modular, and let’s you consolidate a lot of business software into one place where it can all talk to itself. Generally, this makes accounting teams very happy, since invoicing, inventory (esp GAAP), and expenses are all generated mostly automatically. The UI has really improved recently, and performance scales well. Odoo has some good functional tutorials on their website that guide you through using the features.

    Core Odoo cons: If your business has some need outside of what Odoo expects you to use it for, good luck. Unless it’s a minor thing, you’re probably better off changing your SOPs to fit Odoo rather than trying to change Odoo to work for you. Of course, you don’t know whether it’s a minor thing unless you have someone with Odoo familiarity – but we’ll get to that.

    Custom Odoo pros: Almost all of the business logic is written in Python with a fully extensible framework. It’s designed to be modified, and it’s pretty friendly. The docs aren’t great, but the community is. The Odoo Community Association (OCA) maintains a large library of OS extensions, divided by business area. Even if you don’t find what you need, it’s a great place to learn by example on creating custom modules. Simple UI changes are mainly handled by XML, which again is fairly easy to pick up by studying examples.

    Custom Odoo cons: There’s a learning curve, as with anything. Something you thought should be a simple change might turn out to be a pit of vipers. If you’re trying to do web app changes, I will pray for you. Odoo has started to roll out OWL, a JS framework based on React and Node.js, but documentation on JS in Odoo is basically non-existent, and Odoo devs avoid JS like the plague.

    If your company is looking to change, Odoo has implementation partners, who will tailor Odoo to your needs. Partner prices vary widely, and you get what you pay for. It really depends on your company’s size and budget. You still pay licensing, etc. through Odoo itself.

    Avoid odoo.sh (Odoo’s SaaS option) at all costs, I have never seen it go well. Avoid Studio (allows UI changes without coding) at all costs, it turns into spaghetti every time.




  • A lot of your hair care depends on if it’s curly or straight, oily or dry, thin or thick, etc.

    For managing hair in your face, hair bands are good. If you’re not tying it back as tight as a gymnast or something, you’re probably not putting enough strain on it to cause balding. If you want better ways to hold it back, spiral hair ties like these are more gentle and tangle less than normal elastic ones. Long barrettes for the back of the head like this keep hair on the sides from falling into your face. They look especially good with curly hair, and if you’re worried about it looking too feminine (which you probably shouldn’t) you can get subtle black ones. Side braids are a really good way to control the sides, and make you look like a Viking. You would need to get good at French braiding or have someone do it for you.

    For hair care, it really depends on what makes your hair happy. I have very curly hair that goes about halfway down my back. I wash it about once a week, more if it gets dirty. I start with a pre-wash scalp oil. I use a really gentle shampoo or none at all, then a really good conditioner or hair mask meant for curly hair. After showering, I use a de-frizz leave in conditioner, then a hair oil, then a pomade on the tips, all using the scrunch method. I never brush my hair when it’s dry, I carefully comb tangles out in the shower while the conditioner or mask sits. Brushing will destroy curls.

    I highly recommend Jonathan Van Ness for care advice, and his products are excellent, but pretty pricey. Unfortunately, you get what you pay for, and it’s hard to find cheaper alternatives that work nearly as well.
