Batteries have one advantage over over supplies: extremely low noise. Even an good LDO will bump up the noise floor, and a cheap lcsc part will do so too. Plus you’s want a reasonably low dropout and quiescent current, which also increases price. Maybe 10ct in volume is reasonable for such a part - and yes, that will absolutely eat the margin
None of the high end chips were made in Chinese fabs, and the device barely qualifies as a “laptop” besides the form factor. For some bizarre reason they used a USB5744 USB 3.2 5Gb/s hub chip, which tells me the following:
Unless We get better close up tear down photos, this devices primary purpose is propaganda
LPCAMM seems more useful overall as a product.
Only if you need 2-4 sticks, otherwise they take up too much PCB space. Look at servers and how a good chunk of their volume is filled with dozens of sticks. You cant simply lay them down flat.
LPCAMM may have better specs, but DIMM requires a smaller area on the PCB and can make better use of the vertical space.
A slight heating is perfectly normal and nothing to worry about. A microwave is fine tuned to heat food, or more precisely the water within. Other materials such as the glass on the back of the phone also absorb some energy, but only a tiny fraction.
People joke about this all the time, and I here the sarcasm in your comment, but technology has come far since the iphone 6 or 7.
Most high end phones have wireless charging build it. Between the receiver coil and the rest of the phone is a thin sheet of ferrite material to prevent the electromagnetic field from getting to the sensitive electronics. Battery technology has also improved a lot, so much that even relatively cheap phones like the Realme GT Neo 5 charge at 150W!
From the technical perspective the limit is the cable and connector, because there would be too much losses that heat up the cable to dangerous levels and rapidly degrade the contact area in the connectors. Manufacturers don’t want to deal with this security risk, not the increased RMA rates within the mandated guarantee period, so they artificially limit the charging rate.
Thing is: You absolutely can charge at higher speeds if you bypass the cable altogether! A microwave outputs usually somewhere between 150W-1000W, so stick to the lower end to be on the safe side. The screen of the phone must face down, because the charging coil is placed on the back. You also must prevent overcharging by setting the timer correctly: If your phone battery has 15Wh capacity, and you are charging with 150W, you must at most charge for 1/10 of an hour, or 6 minutes (less if you are just topping up your phone).
One final note: fast charging does put increased wear on the battery, so I only recommend to use it when you need it, for example when you need to make a flight and are already running late.
I am aware of the basic arguments behind inflation/deflation, and neither is good in excess.
Typically central banks targets inflation of 2% these days, but we all know the real inflation for necessities is far higher (>4%). Inflation disproportionately affects the poorer - rich people have the fast majority of their wealth “stored” in stocks or real estate, which rise in valuation as people rush into these markets to protect the little they have. I’d argue that inflation rates are artificially pushed far higher then is sustainable, simply because those who decide are the same people who benefit the most.
I consider a low but predictable inflation rate about 1% ideal (0-2% is acceptable short term variation) for the following reasons:
Yes, this idea is not without risks. But the way I see it the forced “we have to improve value by 2% every year” exponential grow can only go on so long before we (humanity) hit the finite limits of this planet.
At least with the government you can vote the bastards out.
In theory. In reality all parties serve the same lobbyists.
Continuous exponential growth is actually something our financial system was DESIGNED FOR. It it makes no sense our inflationary money makes no sense.
This is the most hilarious part. One system literally has exponential growth, while the other is literally created to combat this.

If you really need to hide money from your government, pls consider a pocket change amount of xmr in case shtf. Take care brother, don’t let the feds get you.
One time phone numbers are another good thing, to avoid the ever increasing tracking we are all exposed to.
Love it for donations. Monero specifically is also super fast: open wallet, scan QR, enter amount, hit send. Easily done in 30s or less.
It’s also good for VPNs, because now the VPN provider needs to figure out who owns the IP, rather then looking up the clear name in the payment info. Doesn’t make you anonymous, but reduces risk of data brokers buying your personal info.
In most countries it’s illegal to purchase or sell non-OTC medicine without a doctors note (buyer) and license (seller). Even if government doesn’t care, I’m sure that big pharma would like to keep their profit margins.
nothing-to-hide
In most civilized countries the law is “innocent until proven guilty” - and if I (and the vast majority of people) are innocent, why the fuck is tracking a thing?
My preferred lemmy instance is funded with xmr.
And a deflationary nature is known to cause bubbles.
I mean centuries of inflationary monetary policy also caused bubbles, sooo…

God I wish more artists would support direct donations. Yoink the file from wherever and in exchange sneak 10 bucks into the artists pockets.
Which breakthrough do you mean? Can you rephrase your question?
I find spending a bit more on batteries goes along way. Although the nominal voltage and size may be the same, better batteries have lower internal resistance, ie provide the same current with less voltage sag. This prevent the low bat detection from tripping prematurely.
