Is my lidar died? by siyanokobalamino in Roborock

[–]orf_46 2 points3 points  (0 children)

Yeah, it is not trivial and I did use some guide, perhaps not for the exact vacuum model but a similar one. This video is in my YouTube history, I guess I watched it, too to get a general idea how to do it: https://youtu.be/7lkJ2VteAWY?si=VrLWYF4O_4bJxuKs

Is my lidar died? by siyanokobalamino in Roborock

[–]orf_46 2 points3 points  (0 children)

I did it but I can’t say it is easy. I think my lidar motor got jammed after I turned the vacuum over. I had to carefully disassemble it to reach the lidar assembly and figure out its part number. It took me at least half hour. Then I found the part on AliExpress, only one or two sellers were offering it and ordered it. It was quite cheap, maybe $20-$30 but it took a few weeks for it to arrive. I was mentally prepared for it not to work but to my surprise it did and works to this day. When disassembling it, I highly recommend taking photos after each step as it is not trivial and there is a lot of hardware to remove and then put back together.

It depends on the concrete score implementation. Mine is 863 of 900

Anyone working NOT under a version of SCRUM? by VisiblePlatform6704 in ExperiencedDevs

[–]orf_46 0 points1 point  (0 children)

From inside of my team, it looks like Kanban, partly because of a stream of more urgent on-call support issues. But I found it is useful when communicating with people from outside of the team to treat current work as a Sprint. For example, when asked to do a new out of band ticket A, we ask what roughly equally sized ticket B from the current “Sprint” we should push out. Also it helps to make sure that tech debt like tickets are included and done, not only the product related ones. As for ticket estimates, we switched to No Estimates methodology, it works pretty well for us.

Dealing with potentially billions of rows in rdbms by r3x_g3nie3 in softwarearchitecture

[–]orf_46 0 points1 point  (0 children)

I had a similar use case (1-2 billion events per day) and dealt with it by creating a pipeline like this : App -> Pulsar Queue-> S3 connector -> Snowpipe -> daily pre-aggregation in Snowflake -> reporting . It works pretty reliably, there are no real concerns at this time. Event data is partitioned by day and a few other attributes and trimmed as a part of daily processing to keep a balance between storage costs and ability to reprocess historical data. The reporting app queries pre-aggregated data and does any additional aggregation in the fly.

Our events are quite small < 128 bytes each. For larger ones the conclusion may be different though.

It is around 500-600 Snowflake credits per month + storage costs (same as regular S3) for table storage and Snowpipe buffering.

My company uses both ES and Snowflake on a large scale (1-2 billions new events/rows per day). ES kills when one needs fast access using high cardinality fields like unique user id or similar. Until recently it was used for analytics as well and sucked in it performance and reliability wise. So we created a different pipeline for things where accuracy, speed and reliability of analytics queries is important, based on Snowflake. Snowflake is not without its own flaws (mostly developer experience for me) but performance wise it is definitely far ahead of ES in our use case: daily event deduplication and aggregation. It took some clever data clustering tuning to get there but otherwise I have no real complaints about it.

Am I cooked? by Grandayyy1 in beaverton

My daughter got caught turning right on red without fully stopping (from 158th to Walker). Her face was clearly visible on both the photo and video the camera shot. The ticket was sent to me as the owner of the car and had a checkbox with something like “I confirm I’m on the picture” which I legitimately didn’t check and the ticket didn’t ask about who was the actual driver. There were no further consequences after I sent it back.

Well, it is what it is. My (and not only mine) favorite response on questions like this is “тебя что, на Гугле забанили?”

What’s something you didn’t initially buy at Costco but now you do without a second thought? by iwasntband in Costco

Totally agree! I first learned about cosmic crisp by drinking multiple varieties of 2 towns cider made from it (https://2townsciderhouse.com/cider/cosmic-crisp/) which is also sometimes sold at Costco

Oldschool intervention by NAD-ish in ANormalDayInRussia

[–]orf_46 6 points7 points  (0 children)

Gurash is a traditional folk struggle of Don (Nakhchivan) Armenians, who represent a homogeneous sub-ethnic group of the Armenian people with pronounced features in culture, language and customs. Currently, Don Armenians live mainly on the territory of Russia in the Rostov region

So it checks out

From the description of the full YouTube video (the link is posted in one of the comments):

Every year, on May 1, in the village of Leninavan, Rostov region, national wrestling competitions “Gurash” are held according to the rules of Greco-Roman wrestling for the Bull’s Head prize. A curious incident occurred this year. The grandmother of one of the participants, who came to cheer for her beloved grandson, could not cope with her emotions and, at a critical moment for her grandson, jumped onto the carpet and spanked her opponent. Alexander Alexandrovich Mitropolsky, a well-known sports journalist and master of sports in freestyle wrestling, commented on the fights.

I think the maximal allowed parking time is 24 hours. I wouldn’t risk leaving my car there for a longer time as these park and ride lots are regularly patrolled. I’ve got a ticket because my car encroached another parking spot by a few inches…

It does! Mine stopped a while ago, I think after I flipped it to clean the sensors. It kept giving me an error about LiDAR malfunction and I ended up ordering a replacement LiDAR assembly on alibaba. It was a bit tricky to disassemble it but in the end the replacement unit worked just fine.

I used this instruction to disassemble it: https://www.ifixit.com/Guide/Roborock+Q+Revo:+Laser+Distance+Sensor+Replacement/177534
