jlewallen··on OpenIPC: Open IP Camera Firmware
I just successfully used the Cinnado T23 installer on a Q5 and it worked. It did seem to take two tries, but I could have been being impatient.
jlewallen··on Long live American Science and Surplus
We used to have Electronics Warehouse here in SoCal (Riverside) I miss them but admit I would rarely go. Selection was definitely better than Radio Shack, but catered to an electronics era my personal designs had grown away from.
jlewallen··on Launch HN: Enhanced Radar (YC W25) – A safety net for air traffic control
This is true, for anybody curious about this: https://en.wikipedia.org/wiki/Capture_effect
jlewallen··on Sci-fi books that you may never have heard of, but definitely should read
I'm surprised Greg Bear never came up here. I started with Blood Music, but I've enjoyed many of his books.
jlewallen··on Crafting Interpreters with Rust: On Garbage Collection
Crafting Interpreters is such an amazing work.

There's at least one other Rust implementation of lox that I know of (https://github.com/tdp2110/crafting-interpreters-rs) (no unsafe)

It's always interesting to see how different people approach the problems in their own language or relative isolation. I agree with others here, the real value of the original work lies in avoiding copy and paste.

jlewallen··on Anyone who looks at this code instantly becomes insane
I'd bet they made that function so they had a single place to intervene on text being written, not necessarily for the brevity/aesthetics.
jlewallen··on C++ Programming Questions to Ask on Interview (2017)
Glad to see this as well. I'm about to hire some C++ developers for embedded work and have never been a fan of this type of interviewing, if only because I know I personally don't excel at this style and consider myself extremely competent. I'm hoping to find ways of assessing incoming candidates along the lines you've briefly touched on in this thread!
jlewallen··on Make plastic printed circuits with a standard laser cutter [video]
I had a good experience with AllPCB recently. They even reached out for clarification on an extraneous drl file I had included in the gerbers zip accidentally.
jlewallen··on Banning Netflix, Amazon from Festivals and Awards Is Wrong
I did the same when I moved into a smaller 1 bedroom and had to choose between having a television or my small apartment woodshop. It's been great.
jlewallen··on Why is setState asynchronous?
Do you maintain a 1:1 relationship between reduced state and components? I'm curious because your word choice seems to imply you do and I'm wondering how popular that is if so.
jlewallen··on Building an Operating System for the Raspberry Pi
If I remember correctly, TCL uses a very simple overlay system based on squashfs. Most (all?) of the tooling and package management stuff is also written in bash.
jlewallen··on Building an Operating System for the Raspberry Pi
You might want to check into Tiny Core Linux.
jlewallen··on Mining Bitcoin with pencil and paper: 0.67 hashes per day (2014)
Or just DIY with this:

jlewallen··on Regarding the NiceHash security breach
I had always assumed the wrench would come out because the wrench-holder had at least some knowledge about my Bitcoin holdings.
jlewallen··on Marijuana company buys California ghost town
I've driven through Nipton more times than I can count. It's a ghost town, I don't know how people survive there.
jlewallen··on Spotify preps to go public with 60M subscribers
Thank you for mentioning JQBX!
jlewallen··on CirQuoid – PCB Prototyping Tool
Can't agree more. We have an othermill that's come in handy mostly for intermediate boards that involve mashing together other already made boards. We can get boards back from OSH in a week. We even experimented with a "24 hour" turn around service that skips the soldermask.
jlewallen··on What is the oldest living organism on the planet?
Absolutely fantastic book. I was surprised to learn there were a few examples closer to me that I had expected. Of course, their precise locations are usually obscured.
jlewallen··on Rust on RTL8710 running FreeRTOS
JeeLabs has some stuff on Forth in the uC world: http://jeelabs.org/2016/02/dive-into-forth/
jlewallen··on C++17 – better than you might think
I just took a very quick look at Bazel and saw that Windows support is "Highly Experimental" which concerned me. I've been looking around in this space recently as I'm getting into C/C++ again (ARM uC stuff) and all three platforms are fairly important to me for what I'm doing. I'm a big Gradle fan and Bazel seems like a natural next step if it's not problematic.
jlewallen··on Timer-Tab
When the first wave of smart watches came out I was shocked to learn that timers weren't core functionality.
jlewallen··on tl;dr Legal : Software Licenses in Plain English
Neat. Was just wondering about the Creative Commons Attribution Share-A-Like license with regard to a hardware project and used this to sanity check my interpretation. I also was very glad to find this page when I went looking: https://tldrlegal.com/license/tldrlegal-terms-of-service#ter...
jlewallen··on I’m a Coastal Elite from the Midwest: The Real Bubble Is Rural America
Agreed, and sorry, didn't mean to imply they were similar arguments at all.
jlewallen··on I’m a Coastal Elite from the Midwest: The Real Bubble Is Rural America
I applaud your efforts to understand this as I'm eager to also. It's a mentality or similar to one I've found myself in deadlock with before. For example, I asked a relative of mine if they would sacrifice themselves to save the lives of N number of people and there was no value of N they considered worth more than their own life. This relative found it uncomfortably easy to ignore and even justify the suffering of strangers. Not to say that the GP feels precisely this way. I'd hate to ascribe this particular belief to anybody that didn't directly espouse it.
jlewallen··on Donald Trump is the president-elect of the U.S.
This kind of cavalier talk about unleashing unfathomable misery on innocent people is one of the things that terrifies me most about the future.
jlewallen··on Interactive graphic: Every active satellite orbiting earth
If you didn't notice, try the easter egg: "To see the relative speed of orbits (and possibly melt your browser), press Q and then the space bar. "
jlewallen··on Why we won't be selling Genuino or Arduino any more
I've been working on a project that's using Adafruit's Feather line extensively and I've been very happy. The ones with the M0 chip are great to work with. Edit: They're using ATSAMD21G18
jlewallen··on Musicmap
Anybody interested in this would also be interested in the amazing work of Glenn Mcdonald:

jlewallen··on The TSA is a waste of money that doesn't save lives and might actually cost them
> and passengers wouldn't stand for it anyway.

This. We live in a different world now. I find it very difficult to imagine a plane full of people not standing up together to take down a threat.

jlewallen··on SoundCloud launches Go: a subscription service
I'm a huge Spotify fan and if you've found Discover weekly useful you might like the following other resources for discovering new music:

http://furia.com/newparticles/current.html

http://everynoise.com/engenremap.html

https://open.spotify.com/user/spotify/playlist/3rgsDhGHZxZ9s...

There's more, of course but I agree that many of the curated playlists lean towards popular music. I also follow /r/spotify on reddit and every now and then there's a good playlist on there.
