1) Maybe edit "Ask HN: " into your title?

2) As a low-level C++/C/asm/hardware guy I'd like to get into Rust but haven't yet got started because I haven't had a recent project that would benefit. Not quite your question.

3) When dinosaurs still roamed the Earth many many people thought that a sprinkling of XML would fix everything, with similar levels of hype to the current LLM wave. I do regularly use XML (eg as XHTML source for my Web site, and in my RSS podcast feeds), but not for everything. Also see SOAP and WSDL...


There has been a lot of very aggressive SPAMming here over the last few weeks, and it would not astonish me if things had been tightened up to mitigate it.

But the forum I was an admin for, for many years imposed a "no links in a hurry" rule to deter the morons in a hurry who SPAM...


That makes sense from the moderators’ perspective. In any case, I was able to submit just a little while ago, so it seems to be resolved. Thanks for the explanation.


I find that aggression and unpleasantness and threat of violence a total turn off and did not make it to the end. Also, I think that some of the numbers were probably badly wrong, but I'm not going to pick through the abuse to check...

I spent a long time working in finance one way or another, including as a founder/director of a small e-money issuer, and I have at least from this time ASSUMED that gift cards carry a very inflated AML risk.

Plus I have no desire to carry scrip when I could have fungible cash or equivalent, so I would not buy a gift card. I have received a few.


I think you’re operating with the right mindset.

Looking at the linked story, the trigger seems to have come from redeeming a gift card bought at a major retailer.

Even if the purchaser uses a legitimate store, the user can’t really know the full supply-chain history of a prepaid code, and that uncertainty alone creates room for unexpected flags.

For people who already have a credit card, gift cards are a fuzzy choice if the goal is simply to load balance onto an account.

Something somewhere in the chain probably tripped a rule — maybe fraud-related, maybe a processing anomaly — and from the outside it’s impossible for the user to see which.


IMHO "efficient" isn't really the right term in your second para. The PV generation per W incoming is actually a little lower at higher ambient temperatures, but is otherwise fairly constant.

I assume that you mean higher kWh/y/kWp, ie you get more generation out of a given solar panel in the south each year.


"Effective" might be the better word.

It's unfortunate that "efficiency" has both engineering and economic definitions.


I meant kw h/m^2/d I think, but I'm not sure what the simplest way to say that is

I think you and I are saying the same thing though!


In the GB (UK mainland) grid only ~2% of energy is lost in transmission; distribution is more typically ~5%. And we did put most of our big thermal power generation in the middle of the country, which is now causing difficulties as we need to re-jig transmission to accept offshore wind and interconnectors.

Solar PV on rooftops is great, injecting power directly at the load, eliminating transmission and distribution losses until there is excess to spill back to grid. It would be helpful if we stopped running an entirely artificial timetable in winter that demands heavy activity well outside daylight hours, so that demand better matched availability.


I do.

If this is your thing, at least prefix the title with "Show HN: " please, else it's just drive-by SPAM.
