That's typically in the case of UB, where compilers can make whatever assumptions they want. In this case, even if the code is completely within the C spec, the compiler cannot guarantee that the data is unmodified.

I'm personally still excited about these chips for laptops. Lower power and higher IPC mean same-ish performance as the previous generations, but with better battery life and thermals. Plus you get better turbo boost, better graphics, built-in support for TB3, WiFi 6, etc. Seems perfect for something like the Surface Pro. The Core uarch is getting dated, yeah, but Intel is going for breadth and better integration here and it looks compelling.
Most consumer cards are designed around media storage so they don't last as long.
SC2 is really about attention management- every action you take, like moving a worker to construct a building that you'll have money for in the future, takes time and attention, and good players will take the minimal action needed to get something done and then move their attention elsewhere while they wait (almost like CPU pipelining). This is why players will do runbys/drop harass at the same time as a big fight. It forces the defending player to spend more attention than the attacker, or risk losing key workers/buildings. APM is just a rough representation of the ability to multitask.
From this perspective, AlphaStar's APM doesn't really matter. If it can instantly understand and juggle different scenarios occuring on the map at the same time (scouting, macro, battles, drop defense), that immediately puts it at an advantage, and many pro level strategies rely partially on pressuring the opponent until they make a mistake.
The high level strategy stuff exists on top of all this, and that's what makes SC2 so difficult. AlphaStar is really impressive, but once it understands the game at some level, I think it's inevitably going to be better than human players. Human players are going to get wins off AlphaStar by forcing tactical errors in weird scenarios, but it's not going to look like typical human games.
I put together a NAS/Plex box with a Kaby Lake Celeron and some hard drives, but I was thinking of splitting it out into separate NFS and Plex servers.
I've been looking at ways to get cryptographically secure random bytes on low power micros, and that's the approach I'm taking. The standard for CSPRNGs is AES-GCM, which is a bit heavy, though. Anyone know if Fortuna still acceptable to use?
I'd definitely be up for putting some assembled spares on Tindie once it's complete. I'll post about it on https://hackaday.io/hylian or https://edwardsh.in once things get going.
I'm interested in indoor air quality, so just looking at PM2.5 trends over time would probably be enough for me. An error of 2x without calibration makes it useless for any sort of air quality index calculation, though. Maybe I'll include a header for the HPMA as well and compare the two.

I'm sure there'll be _some_ blue light. I don't know if a prism would be high resolution enough to tell if it's a dangerous level.
I already got the board you linked, supposedly configured for 700 mA. Haven't tested yet. The datasheet for the part says it can go up to 2A[0], so I could potentially modify the feedback circuit for 1A, which would reach the full 3W rating of the LEDs.
One issue with that driver chip is that the PWM/enable is active low, so I think I may just stick an inverter on the output of the Mesh Bee. The SDK for the NXP part has changed since the ZLL repo was updated, and I haven't had much luck getting it to compile myself.
I already have a normal Hue bulb next to my bed on a schedule, similar to the wake up light, but a light strip right above my head seems more appealing to me.
I'm guessing melanopic lux is the lux output weighted over the spectral absorption curve of your eyes?
Some napkin math: I have ten 3W LEDs, and each might produce around 1000 lux when fully driven. If we drive each at half strength, and half of the generated lux is melanopic lux, that's 2500 melanopic lux.
I originally purchased these nice LED strip bars with enclosure in blue[0], but after reading this site by the manufacturers of a commercial green therapy light[1], I was convinced to switch to turquoise/cyan.
Turquoise isn't that popular so I wasn't able to find any strips/bars, and I got these individual 3W bead LED modules instead.[2]
For the Hue integration, I'm using a Mesh Bee + UartSBee v5[3] with firmware from PeeVeeOne[4]. It outputs PWM, and I'm hooking it up to a cheapo constant current LED driver I got from Aliexpress. Since all the LEDs need to be in series for a constant current driver, I'm probably looking at a ~20V power supply to power the whole thing.
My bedframe has a headboard, so I'm planning on 3D printing some mounts that clamp on top.

Figure 3[0] in the paper seems to show that 500 nm is safe, and that melanopsin has high absorption at 500nm, which has important effects on circadian rhythm[1].
Anyone more knowledgable than me know if this setup is safe?

MicroG has been picking up steam. They're doing OTA updates of Lineage + MicroG now.
Maybe this would fit your usecase? It has an Intel m3-7Y30 onboard.
I put in some horrible last minute hacks to optimize for the autograder and raise my grade, like doing a pseudo-bubble sort. Every time I coalesced two adjacent free blocks, I would compare the adjacent nodes in the linked list and swap them if they weren't sorted. That raised my allocation efficiency a tiny bit for certain test vectors- just high enough to bump my grade up a couple points. :)
I switched over from Pentadactyl to Qutebrowser last year and it's way snappier. And with the experimental WebEngine backend, I haven't run into any rendering or performance issues at all. It also has a vertical tab mode, although it isn't possible to have sub-tabs like Tree Style Tabs.

I was able to snag a Glass for a good price when they killed support (before selling it off again after a couple months). I enjoyed using it, and being on a college campus at the time reduced some of the social awkwardness. I could push notifications to my face with IFTTT and the voice recognition worked reasonably well. Ironically, I found the most useful feature to be the camera. It's liberating to be able to wink and get a snapshot of whatever is in your field of view, whether it's some info you want to remember or a small moment you want to share. I'm on vacation now and find myself fumbling with my phone to take snaps of interesting things I want to share way too often.
