Notes

Just a few days back, I got worried about my gym habits: given I am lifting fairly heavy weights at an age of ~35, how badly could I injure myself, especially because I began serious lifting late in my life? Well, I injured my lower back today while squatting. It is painful but I am not sure how bad it really is - I think I’ll find that out by tomorrow. ...

BrainStation invited me as a guest: In terms of the content for the talk itself, the narrative would surround your overall career trajectory and life on the job as a Software Engineer. Attendees: ~20 professionals, who are about to embark on their journey into the world of software engineering, from BrainStation’s ongoing cohort in Vancouver. Where: Virtually, on Zoom. Recording: The talk wasn’t recorded. See slides here. The feedback later was positive: ...

Ask from the coordinator: To break it down further, a potential format for the 1-hour session could be something like: - Introduction to yourself, your career journey, and your role at AWS - A potential case study or work example, exemplifying how you utilize your skills at work - Job search tips for when they eventually begin applying - Q&A Portion Flow: Intro: Major stages of my career and some of my mistakes along the way so that you can avoid those in your career. Adobe and Snapdeal: Adobe Story and e-commerce website: distributed systems and some frontend work. Excited about technology but didn’t know expectations in a corporate environment. They don’t teach you this in college. Tip 1: Ask for feedback from well-intentioned peers. Amazon: 10+ years now. Won’t bore you with all the teams I’ve been part of, so just the interesting ones. Lambda: I joined because I was excited about the potential of serverless. However, a very new field for me and I struggled. VM ballooning. Tip 2: How to make learning durable? Code yourself. Even if you are following a tutorial, rewrite on your own. Anki. Lookout for Metrics: Intentionality == “know what you’ll get out of a certain project”. I work in SageMaker. About SageMaker. I-ML org: we provide cloud based IDEs - JupyterLab or VS Code - for ML. Example of my work: Cosmos. Tip 3: Work backwards from customers, not a solution == solution should follow the problem, not the other way around.

Fairy lights: Red is load, middle is data and the third wire is ground. For power, red is again load and the other is ground. Regular LED strip lights: They mention +ve, ground and data on the strip itself. Make sure data direction is correct while wiring up. In long runs, you need to inject power in between connections because of voltage drop. Even if power supply can provide enough amperage, you may need injection, possibly using the same supply.

An example use case is to pass hard drives to Open Media Vault so that it can club them together behind MergerFS. Helpful commands: # Commands to find the right disk ID. lsblk -o +MODEL,SERIAL,WWN ls -l /dev/disk/by-id | grep -i sdb find /dev/disk/by-id/ -type l|xargs -I{} ls -l {}|grep -v -E '[0-9]$' |sort -k11|cut -d' ' -f9,10,11,12 # Then, pass through. # Here, use the right number for `-scsiN`. Once the following is run, the disk will show up in Proxmox GUI too, under the VM's "Hardware" section. qm set 103 -scsi1 /dev/disk/by-id/ata-ST4000VN008-2DR166_ZDHBBLLT Helpful resources: ...

Don’t want “string lights”. How to control via HAOS? WS2812B. Nice brands: ALITOVE or BT-Lighting. (The latter is available on Ali Express too.) Might need multiple power supplies depending on the length of the lights. Lights usually take DC and will dictate output voltage of the adapter you need to buy. 0.02 amps per LED is safe. (Max requirement is thrice that.) Power adapter should obviously support a higher number. 30 LEDs per meter: 150 LEDs * 0.02 == 3 amps total. 60 per meter -> 300 LEDs -> 6 amps total. Alitove good brand. Calculator: https://wled-calculator.github.io/ WLED controller. Check Athom WLED controller. List of tools: https://quinled.info/2018/10/01/tools-and-equipment/ Diffusers: Muzata is a good brand. Logic level shifting: https://electricfiredesign.com/2021/03/12/logic-level-shifters-for-driving-led-strips/

In the past, when I tried applying some DS record(s) to nic.eu.org, it sometimes complained that they were invalid. To remedy that, I had to format those similar to the following. Specifically, the first 4 fields were missing when it complained. ketanvijayvargiya.com. 3600 IN DS 2371 13 2 64_CHARACTER_LONG_STRING

Kiddo’s third birthday Yesterday was such a great day for me. It was kiddo’s third birthday and I had a lot of fun with him. He too said the same and that made me even happier! In the morning, I was hanging out with him while his mother prepared a little surprise for him - with cake and balloons - in his room. In the evening, I got him a giant “happy birthday” balloon and he was genuinely happy playing with it. For Diwali, we lighted up a few sparklers - his first, wore traditional kurta-pajama, ate chole-puri for dinner and read a book called “How to cheer up dad” which we recently got from the local library. ...

One option is to buy a silicon diffuser with regular strip lights. For example https://www.amazon.com/gp/product/B0B2WMM5WN https://www.amazon.com/Muzata-Silicone-Spotless-Flexible-Enclosed/dp/B08QM6YK7X or https://www.amazon.com/Muzata-Silicone-Channel-Flexible-Enclosed/dp/B0B4FQCB6D Could I use a Shelly RGB with this? Govee’s 1m lights are just $70 though.
