I agree. I've worked with people who actually put in 8 hours of work a day on a regular basis, and it had a huge impact on my desire to get things done. Also, working with Germans.

This is a good overview: https://en.bitcoin.it/wiki/Block_size_limit_controversy#Argu... There's a bunch of political reasons on both sizes as well.

So 1.1.1.0/24 doesn't seem to be in the global table from North American carrier perspectives. It's certainly not a routed prefix for any of my machines in North America. The closest prefix I can see an announcement for on

WebRTC doesn't work for browser control of a lot of IoT type stuff. The really high volume cheapo devices speak things like CoAP or DTLS, and they don't have the horsepower to run something like WebRTC. You'd need a level o

It's true, and radio technology has a lot of inefficiencies in the analog bits. Digital RF techniques help, but the Rx amplifier and downconverters, mixers, and stuff all lose a lot of energy in the process. Also, the watch has a cloc

I don't think I've ever seen any design that didn't have decoupling caps across the power lines. I mean, the Murata parts I use have dozens of megaohms of resistance at DC, and the chip is off 90% of the time anyway so there

TI actually makes a specialized power regulator for their OMAP product line to do exactly that. It's this weird little part that includes the power regulating circuitry and some of the analog audio codec stuff for some reason.

They never needed it from a technical perspective, it's there to make provisioning easier. Because the carriers were pretty decoupled from the baseband ecosystem, there wasn't a really good way to get the subscriber keys into the

Cool! Maybe I'll see you at the next convention we end up at.

I agree... as long as radios aren't involved. Getting parts with the necessary tolerances in low quantities and dealing with the board layout is kind of expensive. The analyzer you need to use to figure out why the radio is acting fu

He puts out some interesting ideas, but he forgot that genome sequencing requires some occasionally toxic regeants that are incompatible with bolting DNA sensors all across town. He's spot on about the data firehose problem, though. I

The microphone doesn't work, TI never released packaged firmware for it. There's source code available that should work, but I haven't seen anyone on the forums that managed to get it integrated into an application, much les

You can't weld regular batteries into a lot of applications, and a lot of IoT applications are mobile and vibration sensitive. You'd be surprised how just a little vibration can really mess up your power supply as the springs bou

I'm actually building a product that incorporates a CC1350 in it, which is the variant that has both a 2.4 GHz and a proprietary sub-1GHz radio. These chips are totally amazing. TI used every trick in the book to help the designers sa

Some of the radio handling bits on MSP430 would be more complex due to the lack of 32 bit support. There's also some third party firmware for e.g. the lowpwan stuff that's only available as Cortex binaries. TI keeps trying to pus

Yeah it's just a regular XO. There's some calibration data they stick in a special flash area at the factory that the radio firmware uses to handle temperature compensation for the chip's internal digital oscillator. I also

Greenfield systems work by startups isn't really done these days. If it's not greenfield, it's probably already in c/c++. If it's not a startup, they probably already have a bunch of expensive c/c++ tooling (

If you worked for one of their bigger customers, chances are someone paid for source access and it was available on an internal server :) I browsed through a copy a few jobs ago and it's honestly kind of boring.

I'm trying to find a devops role, and the interviews I've had are all over the map. As far as I can tell, the closest thing to a devops filter is a SRE filter. A lot of the necessary skills are the same between the two roles, bu

In the dashed case, k is going to be zero or one (a<b is true or false). This works, though: int a=0, b=4; while(a < - - - - --b) { printf("b: %d\n", b); }

The thing about Vulkan is it moves a lot of the boilerplate out of the driver and into your app. That way you can just tell the hardware what to do (and not to do) without the driver trying to read your mind via API calls and optimizing th

Binutils has had debuglink support for, like, a decade now. OpenBSD uses it to put the symbols in a separate file. gdb knows how to find it using information in the executable.

There's this thing called return oriented programming that this is a hard counter to. Return oriented programming replaced shell code a while back when stacks became non executable across the board.

It makes sense to me, but we say "left the barn door open." I think the most natural translation is "gaping holes."

I just did a greenfield deployment of Windows Server 2012 R2 for a big virtualization environment, and ReFS was supposed to be ideal for that kind of application. Everyone I talked to about it told me it was a bad idea, mostly because the
