I'd rather just use TAI and never have to worry about anything. Let the conversion to UTC be the client's problem. Having the length of a second always be the same is kind of important.

I'm one of those kids. I'm about 30 years old now and my diet is pretty much shit. It's actually kind of funny/embarrassing when my shopping cart has bags of pizza rolls and hot pockets. I take full responsibility, but I

That would be odd if true. I've personally created a BSP and did board bring-up on a platform based on the NXP LS1046A (one of their ARM based QorIQ SoCs). That chip uses DDR4 and didn't require any blobs (aside from the Ethernet

I’ve been hosting my own homeserver for a few years on my own personal computer with a residential internet connection. It’s technically a violation of Verizon’s TOS but they don’t seem to care, probably since the traffic isn’t crazy. I hav

Does anyone know if the chip can be purchased from distributors like Mouser or Digikey? If not, will it be eventually? This is the first thing I look at before deciding to invest in learning a new chip. I specifically look for something tha

Not necessarily. The amplifiers sometimes are though. In a normal 2 or 3 way speaker cabinet, you'll have an analog crossover which consists of something like a capacitor in series with the tweeter (high pass filter), and an inductor i

It's funny because most (if not all?) of their datasheets are freely available for download right from their website. Why would they bother doing this?

LCD's don't refresh like CRTs do. The frame is basically persistent until the next frame comes. What _does_ "refresh" is the backlight in the sense that the brightness is controlled by PWM. However, there are many monito

It did take some persuading. I think the main reason I was able to pull it off was ironically because they're not that technical. I bet most of my friends don't even know what Slack or Discord is. That's not to say they'

I'd say it's almost in "just works" territory for everyone except the person who has to actually administer the homeserver (me). I absorb a lot of the complexity for my friends. The only thing that's a little cumber

I can only offer my own personal experience: Matrix has been working well for me for a couple years now. However, I probably have a more narrow use case than you're thinking of. I run a small homeserver and use it to communicate with a

For now. My guess is that one of the reasons Valve has been working so hard on the Linux gaming front is the fear of this changing.

In many cases, these all can use the same pins anyway. Like on some NXP SoCs I've worked with, you just had a bunch of SerDes lanes that could be assigned to any number of functionalities (SATA, SGMII, PCIe, etc.).

It's a discussion. If I saw someone on the street wearing these, it's not like I'd go up to them and be like "why did you waste your money on those?". Anyway, the issue for me is that these are supposed to be audiop

Okay, I wanted to say this before but felt it was too off topic: Never, ever, buy any Samsung appliances. I own a few rental properties. The failure rate on any and all Samsung appliances is insane. Their dryers are the worst. The belt tens

Well, for appliances, those are probably the same brands you'd end up with anyway even after doing research.

> since DMA requires cooperation from the host CPU Not really. I mean, yes, in the sense that the IOMMU has to be configured to allow it, but after that, it's fair game. Any PCI device can read within the inbound translation window.

My first thought was: how come the frame isn't just dropped due to a bad checksum? Then I remembered a piece of Ethernet test hardware I worked with. It had a bad SRAM chip or something which would result in all of the payloads having

For me, it's the fact that I'm going "out". It's somewhat of a special occasion. Similar to the difference between going to a restaurant to eat versus just getting takeout from the same place.
