The trick is to redesign the bricks for worse tolerances. With 3D printers you can print very nuanced springy elements that are impossible to achieve with injection molding. I got some reasonable bricks years ago on…
There is also prompt processing that's compute-bound, and for agentic workflows it can matter more than tg, especially if the model is not of "thinking" type.
Yes, 140W sustained, 160W burst (~10 seconds).
Clickhouse is a network server, duckdb and polars are in-process databases. It's like postgres vs sqllite.
You can take a look at orange pi 5 plus. It has M.2 for WiFi and M.2 for SSD, both PCI-E. It's in $100+ category though.
Orange Pi 5, "plus" version also has 2gen 1-lane pci-e (M.2 wifi), and 3gen 4-lane pci-e (M.2 SSD) and 2x2.5Gbit ethernet. 8nm, pretty power efficient. I've measured it to run at 0.7A@5V idle and 1.2A@5V with all 8…
You'd need to spend at least 110kWh to convert CO2 back to propane, maybe much more. No matter what you do, LPG -> CO2 -> LPG cycle has to be energy-negative.
To be precise, that'd be called MPU -- memory protection unit.
MMU allows linux to provide a "flat" memory space to each userspace process. This memory space is assembled from 4KB pages that can be randomly dispersed throughout physical memory. Say, you want to malloc() 1MB of…
Sorry, I meant to write "voltage regulator" about which parent asked about, not sure how I ended up with "linear regulator".
I believe that without qualification "linear regulator" could be just anything that regulate voltage. Usually you can easily tell from schematics around it if it's some switching IC, an LDO or a module. And if you have…
I've yet to see a voltage regulator IC with built-in caps. DC-DC modules sure, but author argues that this kind of info (module / ic) should be present in schematics. BTW, some linear regulators can't handle ceramic and…
I think he meant that in 3-rd world countries iPhones are luxury items bought by rich people in position of power.
Well racism connotations permeat everything in US, it's overheated/taboo topic there. Not so much in the rest of the world, see two top dictionary definitions from google: To punish (a person) without legal process or…
Let's see: - judged by angry mob -- yes, - no ability to defend oneself -- yes, - killed -- no (though seeing polarization and level of anger here it's possible that he'll be eventually physically assulted), - person…
Um, I'm actually worried that I or other person will be punished for something that they didn't do. In the third world country I live in you'd have to accuse someone and then bribe the judge. Turns out that in US one…
I don't have US cultural background and it looks insane to me, about level of witch hunts or lynch mobs. Like one accusation of peadophilia is enough to ruin a life, and lives of others that dare to voice opinions…
I haven't tried it, but it should be doable. A lot of linux-based rust libs wrap C libs and link to them, or compile their own embedded version during build. Same thing here too, though there could be some problems…
AFAIK LM3S6965 is used in the book as a target for QEMU, and no one endorses to use the chip in actual hw.
Absolutely this. The same price and the Bluepill has much more powerfull CPU. The problem is HAL support. Some periphery is supported, other is not. ADC and DMAs for UARTs were merged just recently. Stuff like SPI / I2C…
For me imaginary input has less details and exists in a separate plane, and it never mixed up with real senses, in the sence that I always know which is which and to my knowledge I've never mixed them up when awake…
Yes. You can also run "watch cat /proc/meminfo" in console and watch "Dirty" and "Writeback" fields to see dynamics (and how long you have to wait).
It should re-poll only when a new file is added. In op's usage scenario it won't be very ofthen. The systemd solution may be even better, though it seems there is no way to ignore changes in temporary files that emacs…
In that setup entr only watches files that existed when systemd service was first started. So new files won't trigger backup. Something like this should work: while true; do find $ORG_DIR | entr -d -r rclone sync -v…
If on Linux, try running fstrim from time to time. More free space makes life of SSD's garbage collector / defragmenter much easier. I've anecdotally noticed that running fstrim reduces freezeups under heavy load from…
