Notes

Setup Find the installable: Router name: Archer C7 v2 AC 1750. While searching for OpenWRT firmware, I had to look for a US specific one (which had -us in its name) and shorten the filename to firmware.bin before installing. UI available here. SSH from computer’s CLI: ssh root@192.168.1.1 Setup password-less SSH once: ssh-copy-id root@192.168.1.1. (This might not work. If so, directly upload your SSH public key from the UI. Also, remove this instruction!) Security - WPA2 with AES. Also Set custom DNS server to that of Next DNS: Network -> Interfaces -> WAN/WAN6 -> Edit -> Advanced Settings -> Use custom DNS servers. Once for IPv4 and IPv6 each. https://dnsleaktest.com/ If one or more WiFi networks die intermittently and you see deauthenticated due to inactivity error in System Log, follow this guide. Essentially, add option disassoc_low_ack '0' to config wifi-iface section of the /etc/config/wireless file. Periodically restart the router: crontab -e Add to the bottom: 0 4 * * * reboot.

Also, see: What’s running on my cloud server?. Here’s a list of things that are running on my Raspberry Pi: OpenMediaVault, which runs the following: A Samba server on a 5 TB hard-drive. Pi-hole: I use the Docker+Portainer way to do that. A scheduled job to back up data to rsync.net A Tailscale daemon that allows me to connect to the Pi, and the services running on it like the above, when I am away from home. An alternative would have been to run something like PiVPN on the Pi and allow port forwarding on my router. However, Tailscale seems way more straightforward.

Mix 1/2 cup of baking soda and dishwashing liquid each and maybe little essential oils. (This will be sufficient for a tub and couple of wash basins.) Apply the mixture and leave for 10 minutes. Scrub and clean it off.

Allegro: Allegro pediatricians don’t visit Swedish hospital on delivery. The following are accepting new patients: https://www.allegropediatrics.com/care-team/providers/jean-sahs-md-faap-doctor-bellevue https://www.allegropediatrics.com/care-team/providers/mona-chhabra-md-faap-doctor-bellevue https://www.allegropediatrics.com/care-team/providers/david-reuter-md-phd-faap-doctor-bothell Seattle Children’s Hospital: Don’t have any.

sudo apt-get install samba sudo mkdir -m 1777 /media/unencrypted_drive/SharedFolder sudo chown pi:pi /media/unencrypted_drive/SharedFolder Put the following at the end of /etc/samba/smb.conf: [global] smb encrypt = off ... [RaspberryPiShare] path = /media/unencrypted_drive/SharedFolder public = no writeable = yes browsable = yes create mask = 0777 directory mask = 0777 Setup credentials: sudo smbpasswd -a pi Then: sudo systemctl restart smbd Tips: Use ext4 file system if using Linux. Connect RPi with router through an Ethernet cable. Make sure the cable supports gigabit connections, otherwise overall throughput won’t go above 100 Mbps.

Deep Learning: Whenever you define a neural network, either as a vanilla Python function or as a nn.Module, it should only take a mini-batch of training data as input. For e.g., for a net that works on images, the input will only be X whose shape could be [256, 1, 28, 28]. Here, 256 is the number of items in each mini-batch, 1 is the number of channels (for gray-scale images) and 28 * 28 is the size of the images. First element of the input is always the batch-size. Loss function should only return a scalar (or a Tensor of size 1). That is because PyTorch’s backward function only works on scalars.

Hikes Mailbox - difficult, so attempt when there isn’t snow. https://www.kingcounty.gov/depts/transportation/metro/schedules-maps/trailhead-mailbox-peak.aspx North Cascades Hidden Lake Lookout - 8 mi. Alltrails. Perry Creek - 10.5 mi. Olympic Lena Lake - looks gorgeous for a summer hike - 7 mi. Google maps. https://www.alltrails.com/trail/us/washington/colchuck-lake-trail - 8 miles. Lime Kiln Trail - 7 miles. Only one hour from Seattle. Cape Lookout - 5 miles - 4.5 hours drive from Seattle. Longer through US-101 but might be prettier. Good camping locations Moran State Park on San Juan Islands. (Has five freshwater lakes for swimming and non-motorized boating.) Spencer Spit State Park. Backpacking Enchantments. (It’s difficult.) Hoh River Trail. Jade Lake: ~26 miles over 3 days with elevation gain, which means a lot of hiking in addition to learning how to backpack. (Probably not that great for me.) Resources: ...

I am considering relocating to London or Vancouver BC next year. Differences between the two places Major: London is very close to India. For e.g., Delhi is just 9 hours away as compared to ~22 hours from Vancouver. We’ll be upper middle class in Vancouver and middle class in London. We won’t starve or anything, just that we’ll have lesser savings in the latter. Salaries will be lower in London. Tech scene less bustling in London, so lesser opportunities to switch companies. Taxes, rents and expenses will most probably be higher in London. While we could buy a home in Vancouver right when we move, we won’t be able to in London for at least a few years. Minor: London’s outdoor scene isn’t as great as that in Vancouver. Should be okay though as Himalayas and Alps are still accessible with a little bit of planning. On the other hand, London is very close to Europe (including Norway and Iceland)! Public transportation better in London. City vibe better in London. It will take slightly longer to get permanent residency in London (~5 vs <2 years). What’s the same Healthcare is free. Education until high school: definitely free in London but probably so in Vancouver too. Other noteworthy things London: Visa situation for parents: While I am on work visa, they can apply for a long-term Standard Visitor visa that lasts 2, 5 or 10 years. That will allow them to stay for 6 months on every visit. Once I become a UK citizien, they can get a family visa which will allow them to stay for a longer duration and make them eligible for UK healthcare. College isn’t free in the UK but could be in some European countries. Vancouver BC Where to live: https://www.teamblind.com/post/Good-places-for-immigrants-to-settle-in-Greater-Vancouver-2hGoqL4c

I began part 1 of the Fastai course sometime in Q4 2019. After an inordinate amount of time for something that I could and should have finished in about 3-4 months, I git pushed my last notebook couple of weeks ago. Nevertheless, I was excited but then, just two days later, Fastai launched a newer, and possibly a more improved, version of their course! The new course is better for a few reasons. ...

Teams in: London. AWS Code Guru. Prime Video (i.e. PV) has a huge presence. Alexa. A new team from IMDb TV, possibly because they have some technology overlap with PV. Cambridge. S3. Kinesis. His team, CDK, is geographically distributed, so he reports to a manager in Seattle. Visa and relocation: Amazon relocates on some tier 2 general work visa. Monthly quota (as opposed to yearly quota in H1B). Took him 2.5 months, even after delays. Temporary accommodation for 1 month. Stay: City Center, which is where Amazon is. (No downtown.) Amazon in zone 1. Buying a home: Zone 1 crazy expensive. Zone 2 & 3 - apartment maybe. Zone 3 onwards - houses maybe. Zone 4 to office - 45 mins one way through subway. Rent: Some US-style apartments, but mostly condos rented out by owners. Managed either by owners or, more commonly, by agencies. Horror stories common. If landloards specific about how tenant should maintain the place, that’s a sign that the place might be good. ~2000 pounds for 2BR in zone 2. No car needed. Good public transportation. Finances: 30-50% salary drop. Significant increase in tax. No car expenses. Life: Cultural diversity is insanely good. Outdoors not as accesible (because you’ll probably take trains which will take time) or as beautiful as that in PNW. Flights to Europe dirt cheap.
