Just to add to the other great response, the “D2” pictured above is configured with one ultraviolet emitter and one “deep” red emitter which is not an easy combination to find. And there is a wide range of emitters to choose from based on preference.
Thanks for posting this. Additionally, I think highlighting some great posts in the sidebar like @containerfan@lemmy.world ’s Anduril diagrms https://lemmy.world/post/1038159 would be great since it shows what’s unique about this small community (on Lemmy).
Moisture could be a problem, found this manufacturer faq:
Energizer Non-Rechargeable Batteries: Frequently Asked Questions Is it a good idea to store batteries in a refrigerator or freezer? No, storage in a refrigerator or freezer is not required or recommended for batteries produced today. Cold temperature storage can in fact harm batteries if condensation results in corroded contacts or label or seal damage due to extreme temperature storage
Simon mentioned these represent 3 lights, hopefully including a single-cell mechanical switch light. There appears to be one e-switch single-cell with charging, and unclear if the 2-cell has tail, electronic, or both.
This s6 config is awesome value and I don’t think you’ll be disappointed, especially running in 18350 mode.
Found this beamshot on the other site but I can also say from personal experience that theres a nicely defined hotspot for a tube light.
A posthumous sequel to 1984? Sounds a bit dystopian to me!
Then again I enjoyed Grendel, a retelling of Beowulf from a different point-of-view, so perhaps Julia could be enjoyed in the same way.
I also still like the older Thrunite catapult v1 which preceded Wurkkos’s ts11. It has reasonable output and good runtime for its size, but ts11 can be found for cheaper and has anduril and aux with a possibly slightly worse driver.
How about Mankerlight MC13 II with SBT90.2 ($110 USD) emitter or sft40 ($65)?
http://mankerlight.com/mankerlight-mc13-ii-90-2/
It’s a larger 18350 light that twists open to 18650. The TIR is similar to Thrunite Catapult v1 and possibly Wurkkos ts11.
.
A 21700 tube was also released as part of a bundle or here: https://www.killzoneflashlights.com/products/manker-21700-tube-for-mc13-ii-e14-iv.
I don’t have this light but it seems like OK value for the higher price (for very short bursts of throw, not sustained).
Agreed. My copy lost this documentation link in the original which gives more detail about the horizontal scaling: https://join-lemmy.org/docs/administration/horizontal_scaling.html.
It seems really straightforward (which is a good thing), each backend Lemmy_server handles incoming requests and also pulls from a shared queue of other federation work.
Time zones are an endless source of frustration, this one doesn’t sound too bad though:
Going forward, all timestamps in the API are switching from timestamps without time zone (
2023-09-27T12:29:59.113132) toISO8601timestamps (e.g.2023-10-29T15:10:51.557399+01:00orZsuffix). In order to be compatible with both 0.18 and 0.19, parse the timestamp asISO8601and add aZsuffix if it fails (for older versions).
Oh sorry I mixed that up, the Wurkkos rep called it “bead-blasted” but that sounds more like stonewashed than brushed.
There were also some alternate finishes for the previews, maybe one will make it into production.
Real RGB? Does this mean we can now control the color?
That’s right, check out https://lemmy.world/post/3287635 for some pics.
I was confused about the engraving but I like your idea to ask for “no engraving” as the option. Only the first 30 get a custom one so maybe everyone else will have the logo engraving.
Olight Obulb looks good for kids. Max 55 lumens and sustains close to that for 3 hours (review), waterproof and with a kid-friendly appearance. $20 on amazon currently.
These don’t provide much illumination but the Niteize rechargeable glow sticks are good kid lights too.
I can see why this data structure might be abused and/or chosen for an inappropriate use-case since it seems to offer a lot of value for the tiny amount of space required.
if you need to know a key is definitely in that space. You still have to perform the lookup.
This is a good description. I think the name “filter” is appropriate for their best use cases, when you want to remove members of some other set if they are probably members of the bloom filter set, and can accept that you might remove some extras due to false positives.
Problems like that come up from time-to-time.
This data structure uses a 2-dimensional array to store data, documented in this scala implementation: https://github.com/twitter/algebird/blob/develop/algebird-core/src/main/scala/com/twitter/algebird/CountMinSketch.scala. I’m still trying to understand it as well.
Similar to your idea, I had thought that by using k bloom filters, each with their own hash function and bit array, one could store an approximate count up to k for each key, which also might be wasteful or a naïve solution.

I haven’t used them in Spark directly but here’s how they are used for computing sparse joins in a similar data processing framework:
Let’s say you want to join some data “tables” A and B. When B has many more unique keys than are present in A, computing “A inner join B” would require lots of shuffling if B, including those extra keys.
Knowing this, you can add a step before the join to compute a bloom filter of the keys in A, then apply the filter to B. Now the join from A to B-filtered only considers relevant keys from B, hopefully now with much less total computation than the original join.
Collage sounds really interesting , will check it out. Another variation on bloom filter I recently learned about is count-min-sketch. It allows for storing/incrementing a count along with each key, and can answer “probably in set with count greater than _”, “definitely not in set”.
Thanks for adding more detail on the DB use-cases!
A more focused throw channel with the same color temperature as the flood channel would be great.
Sft-70 is 6 volt right? Otherwise this would seem like the perfect spot for an sft-40 3000k.
Well yes, but this is an internet forum for flashlights. That’s pretty weird too.
If you’re willing to try Aliexpress, Convoy offers a cheap twistable AAA light with a basic low CRI emitter in three color temps for under $10. It’s better than other twist lights I’ve used like because both “on” and “off” are tightly secured to the body so the light won’t fall apart or turn itself on.
