- Comment on The Sodium-Ion Battery Revolution Has Started 4 days ago:
CATL wholesale pricing per kWh is already almost 50% below lifepo with a goal of sub $20/kWh pricing in coming years.
- Comment on The Sodium-Ion Battery Revolution Has Started 4 days ago:
More durable, cheaper, can be operated at a wider temperature range and much safer, but at a cost of lower energy density.
They look like a big step forward for uses where density matters little, like grid energy storage or small scale home backups.
- Comment on Does the US charge tariffs on handbags from France? 2 weeks ago:
Courier company will nickel and dime you every chance they get. E.g. paying customs fees online before package arrives vs paying with CC on delivery can save you $10-15 in same cases.
- Comment on Does the US charge tariffs on handbags from France? 2 weeks ago:
De minimis was suspended for all imports into US several weeks ago.
- Comment on Does the US charge tariffs on handbags from France? 2 weeks ago:
It’s more complicated:
- Tariff depends on the country of origin of the handbag - simplifying a bit where it was made, not where it was sent from. E.g. if it was made in Vietnam you are paying tariff for Vietnam even when buying from France.
- Country of origin has to be declared (and sometimes documented) by the seller. Not all of them know how to properly do that.
- You pay tariffs on full invoice, including shipping costs.
- If what you are buying is discounted and both full price and discount amount are on the invoice you might initially be forced to pay tariffs on full price and then fight customs to get a partial refund. This usually happens when the seller is sloppy when filing customs paperwork or just includes an invoice and has customs sort it out.
- There will be extra fees for customs brokerage. IDK what the current rates are with major courier companies, but I’d guess $30-60
- Once you go over $2500 shipment value it gets more complicated
Source: handled customs for about 40 shipments from Canada and EU to Amazon warehouses in the USA.

- Comment on Dedicated service user or not ? 3 months ago:
It’s always effort vs risk.
Since it’s a do once and forget kind of thing I’d rate effort rather low.
As for risk in the worst case scenario a single service being compromised means all of them are with the attacker getting access to everything those services can access, including all the credentials. Will you make an effort to be on top of all the updates for all services?
At home all containers for any service get a separate user. At work every container does.
- Comment on Pensioner robbed of $1,338 is taking NAB to court for millions 3 months ago:
He’s asking for exemplary (punitive) damages - something that can be granted for egregious conduct as a way of scaring others from doing something similar. Since it’s supposed to scare banks into compliance the amount is not that crazy.
- Comment on What are some FOSS programs that are objectively better than their proprietary counterparts? 6 months ago:
So am I. I’ve been writing software for a living for almost 20 years, so when I wanted to make a slightly more complicated box to 3d print openscad was my first choice too. Then I tried freecad and hated it with passion. Eventually I ended up making it in solidworks - it sucked the least of the tools I’ve tried.
- Comment on What are some FOSS programs that are objectively better than their proprietary counterparts? 6 months ago:
It’s great when what you are designing is best described as code, but I find it absolutely not worth the hassle otherwise, because even basic things like chamfers/fillets are extremely hard to execute.
- Comment on Trump Admin Considering Giving $10,000 To Each Person In Greenland To Annex The Island 6 months ago:
Greenland gets about that much per person in subsidies every year, so gl with that.
- Comment on How likely is it that Trump will be the first President assassinated since Kennedy? 6 months ago:
As much as I hate the guy I hope he isn’t killed. The last thing we need is republicans having a martyr, especially before they find out how bad for them he is.
With tariff fallout there are decent chances they will not have a majority for a long time. After the tariff act of 1930 they went from having 14 seats more than democrats to a low of 16 seats out of 96 In senate in just 8 years. After that they had a senate majority once and congress majority twice in the next 50+ years.
- Comment on Is cops being evil/lazy/incompetent a USA specific thing, or is it the same everywhere in the world? 7 months ago:
Mandatory training to become a police officer:
- US: 600-700 hours on average, much of which is gun and combat training and not policing
- Canada 2080 hours
- Spain 2880 hours
- Germany 4000 hours
With that little time spent training and heavy combat focus a US cop might get as little as 2-4 weeks of training on everything that a cop does that doesn’t involve guns.

- Comment on What is your ideal ambient humidity? 8 months ago:
Check silica packet effectiveness below 50% humidity… It’s not great. Molecular sieve on the other hand has no problem getting humidity below 5%. I managed to buy a 10kg bucket of 3A sieve for about $120 and it’s going to be enough for many years.
- Comment on What is your ideal ambient humidity? 8 months ago:
I store all my filament in ziplock bags with some 3a molecular sieve - even after 2 years in 45-65% humidity at 21C room I don’t have to dry PETG.
- Comment on What kind of special knowledge or equipment does piracy groups have? 11 months ago:
- HDCP had flaws and keys up to version up to 2.1 were extracted/reversed. In addition to that there is hdfury device that legally and following HDCP licencing terms downgraded 2.2 to lower 2.x versions to provide compatibility. They got smarter and blocked downgrading in later versions. Blocking HDCP older than that would also break compatibility with devices that don’t support versions of the standard newer than late 2012. Add a capture card and you are set.
- Widevine L1 keys were extracted from a Qualcomm CPU in 2021. They are also stored in Intel CPUs in SGX which had so many flaws over the years I’d be surprised nobody grabbed keys at some point
- Both audio and sound has to be decrypted and analog at some point - you can capture it if you have the hardware and willingness to e.g. grab it at a LCD display ribbon. Not as good/convenient as decrypting it, but it is an option.
