So like LiveContainer[1] which works around ios's signing requirements

It's not an e-ink display, but rather a monochrome transreflective lcd. [1]

I'd say they are bad because they aren't very power efficient. There are boards with nrf52 chips that already have qmk support iirc.

Yes, custom cores in the sense of what apple does.

The cores don't serve the same purpose as the M1 cores. M1 is optimized for single thread at the cost of die size (and a bit of power). I don't have exact numbers, but say the apple M1 core takes 1.5x the die area of N2, the you'd get better performance by putting in 1.5x the number of N2 cores.

Fairing recovery is not abandoned, they decided to fish them out of the water after a soft landing instead of catching them with a net.

Digikey pricing is not indicative of actual volume pricing, especially for FPGAs where they are often many times overpriced when buying from distributors. I doubt the board is sold at an loss, probably sold at a small profit, not that's it's really significant for a low volume dev board.

The circulator[1] is an analogous component in rf, it send the incident power from any port down to the next port, so you can take one port to be the bidirectional connection, and it splits the signal into transmit and receive connections.

The trick to doing smd soldering is reflow. On all budget all you need is a hot air gun, if you put solder and flux on the pads manually before placing the components. With a stencil and solder paste you can save the time tinning the pads, and placing a component every few seconds is quite possible. So if you work really hard and quite possibly break your back you can assemble this board in a day :)

It takes a combination of software and hardware to get good power consumption. In this case, assuming the author has implemented sleep modes on the microcontroller, it's probably the 3g module being not very power efficient.

This is only a cpu core. It lacks the memory controller and peripherals that make a SoC work. It will probably never make its way into a chip tapeout.

In recent years the node names don't correspond to any physical dimensions of the transistors anymore. But since density improvements are still being made, they just continued the naming scheme.

It's in a QFN not QFP package

mitigations=off is all you need on a recent kernel

I'd love to know what makes this theorem so useful, but I doubt I will understand much considering this is in an area of math I know almost nothing about.

I imagine it must be very hard to explain the theorem while making it accessible and interesting to the general public.

In a previous post he said it's 8 years old

> Bitcoin appears to have greater staying power than most nations and currencies in history.

I would not make that statement so soon. Bitcoin has only existed for 10 years. Most nations and currencies, at least in recent history, have lasted for much longer than that.

The booster's trajectory targets offshore or away from droneship in case landing burn fails. The landing burn brings the booster onto the landing pad. See CRS-16 where the booster landed in the water when the booster lost roll control when the grid fins failed.

There's a typo in launch.sh that breaks when you try launch in debug mode

> "{$DEBUG_PORT}"

For rendering yes. For video decoding no. Chromium needs a patch to use VA-API[1].

The title is misleading, they have most likely only been dead for a few months since their bodies were found still decomposing.

You can take screenshots by plugging a usb stick into the scope

Most computers have an Embedded Controller (with integrated flash) that does a lot of motherboard/system specific stuff like power management, flashing leds and even scanning the keyboard matrix on laptops.

Smallest feature size no longer correlates with transistor density in recent years. So manufacturers just use the number to convey increases in transistor density.

See https://en.wikichip.org/wiki/technology_node#History

That one has an i7-5557U, compared to the i7-6500U the current one is selling with, so probably an early prototype.

They say on their website "Atheros 802.11n w/ Two Antenna"

Wi-fi cards are actually a huge issue if you are concerned about privacy. You have no idea what the firmware is doing, and it has access to your entire memory through the pcie interface, and the internet at the same time.

I've never heard of this and I grew up in China. Can you provide a source?

Cortex M cores don't have MMUs, so they cannot be affected. Also in embedded applications you would only be running trusted code anyway

It seems like the domain expired, and now it redirects to a gambling site.
