csnewb··on Ask HN: Have you observed any Covid-19 related panic buying yet?
I'm a Bay Area resident. I went to Costco today at 9:00 AM and it was an absolute shitshow.
csnewb··on What'll happen to all the Kindle books when Amazon dies?
Yes, I do.
csnewb··on What'll happen to all the Kindle books when Amazon dies?
Good question, and that's the main reason I prefer to own physical books over Kindle books. I know that I own a physical book, but a Kindle book can disappear at any moment. Kindles are great while traveling though.
csnewb··on What are some healthy, creative ways to spend downtime while waiting for code?
Go to the gym and lift weights or do some cardio.
csnewb··on Ask HN: Coolest CS Subfields?
Security
csnewb··on Books Recommendation: Breaking down a problem into sub-problems (in general)
Problem Solving 101 by Ken Watanabe provides a toolbox of problem solving techniques. One method I've been using to decompose problems us to use a "logic tree". Start here: https://en.wikipedia.org/wiki/Issue_tree. Another technique is to first explain the problem and solution at a high level (pretend you're explaining it to a friend or coworkers), then write pseudocode for how you would solve it, and then convert that pseudocode to actual code.
csnewb··on Ask HN: How do I find an apprentice?
If you're located in the Bay Area I'm up for it. Or even working together remotely. I'm somewhat junior (3 years of experience) but mentorship is something I've been looking for in my career.
csnewb··on Ask HN: In CS, is it better to be highly specialized or generalized?
Become a T-shaped developer. Have a broad range of skills with a deep expertise in one.
csnewb··on Ask HN: A separate team for fixing bugs?
Oh look, a thread about my current company. I'm actually in a bug fixing team right now separate from the main product development team. It's an extremely difficult position because as someone else mentioned, you need an incredibly deep understanding of the system to truly resolve these bugs. Unfortunately I work on a 20+ year old legacy codebase with minimal documentation and poorly written code, and our dev team is unwilling to spend any time helping to resolve these issues. They're too occupied with churning our new features, while the bug team is abandoned to clean up the mess from all this new code without any sort of help whatsoever. Another perspective that many people don't discuss is that only doing bug fixing is soul crushing. With things constantly breaking, it can be very mentally draining having to fix them. That being, the attrition rate on the team is quite high because there's very little career growth or satisfaction in being a bug fixer. This experience could be exclusive to my company, and I can't say whether it's effective for the business to run things this way since I'm still really early in my career.
csnewb··on How to Ace the Google Interview: Ultimate Guide
Should be titled "How to Ace the Technical Interview in the Bay Area". Even absolute shithole bottom tier companies or unknown startups are asking these questions. Write perfect code on the whiteboard or get rejected. You have to put in A LOT of time into preparation even if you don't want to work at Google, which is ridiculous.
csnewb··on Ask HN: How did you improve your problem-solving skills?
The books that I've read that have helped me immensely: How To Solve It, Problem Solving 101, 5 Elements of Effective Thinking, and Peak: Secrets from the New Science of Expertise. Trying to improve my problem solving ability in coding forced me to look inwards and analyze my thought process to understand why I'm able to solve some problems and unable to solve others. Ultimately I've realized the root cause of my inability to solve hard problems was poor problem decomposition. Every hard problem can be broken down into subproblems, and those can be further broken down until they become easy enough to solve. Then you just connect all the pieces together. It takes a lot of deliberate practice with many problem types to be able to recognize how to decompose problems, however.
csnewb··on A Humility Training Exercise for Technical Interviewers
So basically you're asking for a HackerRank screening. In my experience, if your code doesn't pass 100% of all test cases you get automatically rejected. At least with a human interviewer, they can evaluate your thought process even if the code itself isn't quite correct. Trust me you don't want to me interviewed only by robots.
csnewb··on Ask HN: How to practise Algo/DS for interviews that are every 2-3 years?
Spaced repetition: https://en.wikipedia.org/wiki/Spaced_repetition

If you don't actively review this material you're going to forget it. I created my own study guide for data structures/algorithms that I frequently review to prevent forgetting any concept. Every few days, or at least once a week, I'll take a blank sheet of paper and try to write down everything I possibly know about every fundamental data structure, including pseudocode and real code for operations such as searching/insertion/deletion. When I go through interviews I read my notes and do this active recall exercise at least once a day every day. Unfortunately there's no shortcut and you have to actively think about and code this material in order to remember it (if your day job doesn't involve knowing those things).

csnewb··on Ask HN: How much time to devote to learning algorithms vs. creating software?
Technical interviews only test your data structures and algorithms skills and your actual work experience is mostly irrelevant. If you want to crack an interview, grind leetcode and practice writing code on a whiteboard. If you want to become a better developer, create software.
csnewb··on Why Do Rich People Love Endurance Sports? (2017)
The San Francisco Marathon (for 2019) costs $233 to register for the full marathon, and about $143 for the half. It's definitely overpriced here.
csnewb··on How to Be Successful
#2: Have almost too much self-belief. Self-confidence has been something I've struggled with my entire life, to the point where its crippled my career growth as a developer. I've been told that I'm a good developer, but if I only believed in myself I could go a lot further and become truly great. However, it's hard for me to believe in myself when I don't have a lot of data points to prove that I AM competent and capable. Over the past 3 years of working full-time yes I've accomplished some things, but none of them were truly difficult or ground breaking. I'm always pushing myself harder to learn more and get better, but it never feels like its having enough impact on me actually growing. So if all I have are at best average/mediocre accomplishments, how do I convince myself that no, I AM great, that I CAN do this? I feel like if I start having a lot of self-belief it'll just become a lie that will blind me from my weaknesses and cause me to stop growing.
csnewb··on Ask HN: What are must-know concepts for back end development?
Read these two books: "HTTP: The Definitive Guide" and "Web Scalability for Startup Engineers".
csnewb··on When hiring senior engineers, you’re not buying, you’re selling
That's hilarious and so true. Last year I interviewed for a senior back-end engineering position at a well known mid-sized company in the Bay Area. They put me through 2 technical phone screens and a 6 hour onsite interview, grilling me in detail about system design, domain knowledge, personal experience, and of course doing endless exercises of writing solutions to algorithmic problems on a whiteboard. I really felt like I nailed the interview but they still rejected me because they thought my technical skills weren't good enough. 7 months later I start applying to jobs again via LinkedIn, and guess what, that exact same position on the same team is still open. It seems insane that during the past 7 months they couldn't find a single person to fill that role. Makes me wonder if they know what they're really looking for.
csnewb··on Ask HN: What are the best-designed products you've ever used?
2015 15" Macbook Pro. The screen size and resolution is perfect for coding and watching movies. Keyboard is super comfortable, the touchpad is the best of any laptop I've ever used. The physical size and weight of the laptop is hardly noticeable in my backpack. It integrates flawlessly with all my peripherals like a mechanical keyboard, mouse, external monitors, etc. macOS is also sleek and simple. The overall experience of using that MBP is a pleasure.
csnewb··on Ask HN: What books/activities do you recommended for being more charismatic?
You can't learn this in a book. You need to put yourself out there (in social settings) and learn through trial and effort. Much like reading books about weight lifting won't make your body grow muscle, you need to actually get inside a gym and put in the work.
csnewb··on Ask HN: A project you gave up on? (time, cost, you were not smart/ready enough )
I was given a take home project to complete as part of an interview process for one company. I was given 48 hours to implement a basic chat server in Golang. I didn't know Golang, but the hiring manager thought it'd be a good challenge to see how quickly I learn new things and deliver results. I spent an entire weekend learning Go and tried to be honest about using only 48 hours to write the application. I wasn't given any skeleton code, had to implement the whole thing from scratch. I never made an entire web app from scratch especially in language I wasn't familiar with so the learning experience felt like drinking from a firehose. I learned a ton but couldn't complete the project because it was a bit too much on top of my full-time job and going through interviews with other companies, so I submitted my barely functioning code in shame and knew that was automatic rejection right there. I wonder if I'm just a shitty developer or if given enough time I would have been able to make it work.
csnewb··on Ask HN: Books you plan to read in 2019?
Sci-fi

- Ready Player One

- Pattern Recognition

- Burning Chrome

- Do Androids Dream of Electric Sheep?

- Hyperion

- A Fire Upon The Deep

Technical (backend development + security)

- HTTP: The Definitive Guide

- RESTful Web Services

- Designing Data Intensive Applications

- Web Scalability for Startup Engineers

- The Art of Software Security Assessment

- The Web Application Hacker's Handbook

- A Philosophy of Software Design

- Clean Architecture

- The Go Programming Language

- Refactoring (new 2nd edition)

- Algorithm Design Manual

- Cracking The Coding Interview

I'll definitely be able to get through all the sci-fi novels, but not the technical stuff. At minimum I need to go through the technical interview prep books, refactoring, and designing scalable applications.

csnewb··on Migration trends in U.S. metro areas
I'm a Bay Area resident but visited Austin for the first time over the weekend. It's an amazing city, but the locals were openly unhappy about any more Californians moving there. Seems like there's already a big ex-CA population.
csnewb··on Ask HN: Your most useful purchase of under $100 in 2018?
I recommend Limber 11 to get started: https://www.bodybuilding.com/fun/limber-11-the-only-lower-bo...

Eventually you'll need to fine tune the program according to your needs. Becoming A Supple Leopard is basically the encyclopedia for mobility programs/exercises: https://www.amazon.com/Becoming-Supple-Leopard-2nd-Performan...

csnewb··on Ask HN: Your most useful purchase of under $100 in 2018?
$20 foam roller. As someone who lifts weights, runs long distance, but also sits at a desk for 8+ hours a day, my body gets so incredibly tight by the end of the day. As soon as I get home I spend 20-30 minutes working on mobility from my neck down to my ankles. The foam roller helps a lot with that. It's painful but I feel so much better after.
csnewb··on Ask HN: How many times have you been rejected?
This year I've failed about 15-20 technical phone screens and two onsite interviews. These were SWE roles at SF Bay Area companies and I have 3 years of experience working in the area as well. I'm going to take a break for a few months, do some more interviews next year, and if that doesn't work out then I'm giving up on trying to find a new software engineering job and will become a lifer at my current company.
csnewb··on Ask HN: Does anyone else keep their own knowledge wiki?
All my notes are stored in Google Docs, but I sometimes worry that if it ever suddenly becomes deprecated or I'm locked/banned out of my account for whatever reason I'll lose many years of important knowledge. I wonder if I should copy/paste all my notes from Google Docs into plaintext files.
csnewb··on Ask HN: How do I consciously improve my reading and retention skills?
To improve information retention you should exercise your "information retrieval". Basically, take a sheet of paper, write down the name of a topic you're learning or a book you're reading, and then write down as much information as you can remember about it. Compare your notes against your previous attempts to identify what you need to focus on studying/remembering more. Repeat this exercise until you can comfortably recall all the main ideas.

Two books I highly recommend that can help you with improving reading and learning skills: 1) "Make It Stick" by Peter C. Brown 2) "How To Read A Book" by Mortimer J. Adler.

Good luck!

csnewb··on Ask HN: How do you re-engage with your sense of wonder?
I work in the security industry, and for me, it was attending the DEF CON conference. I was feeling very demotivated and burned out at my current job, but going to the conference rekindled my drive and thirst for learning. Being surrounded by so many like minded who are incredibly passionate about their craft, and actually talking to and learning from these people opened my eyes to how many interesting things there are to learn. Of course, the presentations and workshops were very educational as well. I just bought like five books that I want to devour as soon as I get home, and start working on more projects in my spare time. In your situation, maybe going to a conference or even a local meetup group, or just in general surrounding yourself with passionate people, might reignite your sense of wonder. Good luck!
csnewb··on Ask HN: Is there a MOOC provider that deals in more advanced topics?
IMO once you're past the beginner stage of learning a technical topic (which is what most MOOCs provide), you have to either develop side projects or work on open source projects to learn more advanced concepts.
