- Watched I Think You Should Leave with Tim Robinson. Some good sketches, some average.
- LSU national champs.
- Bought, trimmed, brined a $15 prime brisket.
- Since I have the tax/house loot sitting in my BOA, I’m temporarily eligible for preferred rewards. Not gonna get another card or anything, but there are some small perks like no ATM fees at non-BOA ATMs, etc.
- Paid the $53 parking ticket for the garage next to tower 12 last friday.
- HDFS = hadoop distributed file system. Part of the Apache Hadoop suite.
- Did a cloud product comparison review between the gigantic stacks of AWS vs Apache vs Azure.
- While I was working on the Netflix takehome assignment, the position was closed (over the weekend). Dunno if that meant filled or headcount-cancelled. The hiring manager emailed personally and said that she liked me and wanted to personally forward to another hiring manager. I looked through all the open engineering reqs in Los Gatos / Los Angeles and asked for the python runtime group.
- I really do like 23andMe.
- Forget privacy, murder charges, general data paranoia. Accountability is good. More data is good. And this data is about as fundamental as it gets.
- Leads to connections. Leads to drugs. Leads to wellbeing.
- It’s a fantastic business model. You’re paying them to give them data, which is their actual product.
- Average US credit score in 2019 was >700. Higher than I thought it would be.
- Google and FB building little towns of housing complexes near their headquarters to offer affordable housing (+ convenience, – work/life balance). https://medium.com/cxo-magazine/google-and-facebook-are-building-the-ultimate-perk-housing-3ec8ba3c4f6b.
- Current vegas money lines, niners and chiefs both favorites at -320.
- The most career interceptions is 81. There used to be a lot more. The most for active players is 35, Richard Sherman.
- Features like search autocompletion should have a response time <100ms.
- A trie (pronounced try) is a specific type of tree, where the nodes are characters.
- For the english alphabet with 26 letters, it’s just a tree with:
- Root node = null.
- Each node can have up to 26 child nodes, one for each next letter.
- Traversing down any path spells a word, (the path being the return string).
- With these properties, you can look up a word quickly. O(l+n), where l is the length of the prefix that you’re checking against, and n is the number of nodes underneath that trie subset (because you have to traverse all of them). Then you’d usually do a sort, for klogk more, where k is the length of the valid words you found.
- This is used for stuff like autocompletion / look-ahead text.
- Jeddah Tower will open this year and surpass Dubai’s Burj Khalifa as the tallest building, but then the Dubai Creek Tower should open the year after that and take the crown back. It costs over $1b. It will be over 1km tall.
- Remember to consider a timescale. If a particular computation is expensive, but the user doesn’t need accuracy of the data down to a resolution of seconds/minutes, just compute it and cache it once an hour or something!
- Jeop GOAT day 4. Ken won!
- FTP = file transfer protocol.
- I didn’t know LinkedIn was the original creator of Kafka; Apache is simply the steward nowadays.
- Wanted to subscribe to highscalability’s RSS feed, but gmail doesn’t offer native support for RSS (anymore). This is crazy. I don’t want to have to create an account with a standard newsreader and use it as a middleman. I’ll just check the blog manually, but it’s a shame to have to do so in 2020.
- Bought a new food processor.
- Amazon called, basically said that hiring was a consensus, but they were considering bumping up from II to senior. They wanted to get more data points to confirm, so they requested a second, shorter, onsite interview with more senior developers.
- 2hrs instead of 6.
- Same format, half behavior and half technical for each hour. 1 would be another problemsolving question and 1 would be another system design question.
- The behavioral halves would be split among a specific 4 of the LPs: think big, invent and simplify, be right, hire the best.
- Overall, I feel good about this? It’s more work, but it’s the chance for an early promotion. 2hrs for a stressful onsite is easier than working for a promotion internally for a year. In the worst case, I hope there’s no offer retraction for the lower level if the second onsite goes poorly, for some strange reason. In general, I’m happy to see that the interviewers recognized some good principles and suggested higher leveling without my solicitation – the exact opposite of SpaceX :). Moving forward with gratitude, no matter what happens.
- Emailed Citadel and Google to let them know so that we can accelerate those tracks to stay in sync.
