Similar in how you order, not similar in price at all. Order of magnitude more expensive for hobby-grade boards.

> maybe only 20% higher depending on what service you take

For higher-end board that seems likely. For cheap hobby-grade boards just the job fee[1] is more than 10 boards delivered is from JLCPCB.

That said, thanks for reminding me. Will definitely compare next time I need boards.

The job fee seems to include shipping, which makes it more reasonable. But Aisler's "estimated dispatch" for the budget service is Jan 26. That's 10 business days + shipping, making it not very competitive with JLCPCB's 10-15 business days including the slowest/cheapest shipping.

Express service adds ~20 EUR, roughly the same cost as picking DHL express delivery on JLCPCB.

Just checked myself using a board I already had manufactured, and can confirm it's a lot higher than JLCPCB or PCBWay.

Maybe for rapid prototyping it is okay, but at scale, to make one board is more than the entire selling point of the whole device.


Reminds me of Runge-Kutta methods[1] of numerical integration, specifically RK2 since they only have one intermediary update.

The theorems took me right back to my finite element methods class at university, with Banach spaces and proving convergence of fixed point functions using Cauchy sequences.

Hopefully someone more well-versed in the field can chime in on the meat of the paper, looks like a good win from afar.

I recall reading about a paper in SciAm or American Scientist a couple of decades ago, where they had trained a ML model to predict regional conflicts or civil wars. The main input was scarcity of food, mainly through price IIRC.

They trained it on historical data up to the 90s or so, and had it predict the "future" up to the time of the article. And as I recall it did very well. They even included some actual near-future predictions as well which also turned out pretty accurately as I recall.

Which I suppose isn't a huge surprise after all. People don't like to starve.


Link?

My memory isn't good enough to recall the name of the paper, however doing some searching I see the field has not stood still. Here[1] is an example of a more recent paper where they've included more variables. A quote from the conclusions:

The closest natural resource–society interaction to predict conflict risk according to our models was food production within its economic and demographic context, e.g., with GDP per capita, unemployment, infant mortality and youth bulge.

As a Windows user since 3.x days, I complain mostly about UX issues these days. It's also clear leadership is not aligned with what I want with my desktop.

I've hardly had hardware issues since I moved to Windows 2000. Sure some, but few enough I can't recall any in particular.


It was, some 25+ years ago.

No it wasn't. Only in your head

Don’t be a troll.

Over 90% of desktops had Windows back then. So yea, that's everybody. Unless you're being pedantic because one guy was using IRIX on an SGI workstation, or the odd Mac.

> csv files. MS Excel can read some malformed csv files.

At work we have to parse CSV files which often have mixed encoding (Latin-1 with UTF-8 in random fields on random rows), occasionally have partial lines (remainder of line just missing) and other interesting errors.

We also have to parse fixed-width flat files where fields occasionally aren't fixed-width after all, with no discernible pattern. Customer can't fix the broken proprietary system that spits this out so we have to deal with it.

And of course, XML files with encoding mismatch (because that header is just a fixed string that bears no meaning on the rest of the content, right?) or even mixed encoding. That's just par for the course.

Just some examples of how fun parsing can be.


I feel product management from a lot of large companies is often very disconnected.

A semi-random recent example from someone else, Samsung changed contacts list in recent update, so now recently added contacts is above favorite contacts, and it's done in such a way I now have to scroll to get to my favorites... like WTF.

Samsung aren't unique though. Microsoft for example has spent the first few years if each release of their OS usable since Vista, with the exception of Windows 7.


I'd don't think they are disconnected. That would just attribute carelessness where malice should be attributes I believe they are intentionally removing these features to push some metrics to increase their bonuses.

I thought that level was great. To me it really sold someone with a jumbled up mind trying to push on through.

Without that level Max Payne wouldn't have been anywhere near as memorable for me.


Split the difference with std::moveable().

Also signals it doesn't actually move, while remaining just as fast to type.
