I use Go as my preferred language and I think the author is mostly right. There’s no way for me to know or even check what are the possible errors this function can return? Sure, sometimes a comment in the library might be illuminating, but

genuinely curious, can you steel man stored procedures? views make intuitive sense to me, but stored procedures, much like meta-programming, needs to be sparingly used IMO. At my new company, the use of stored procedures unchecked has reall

off the original topic, but on topic for this - Yes! Gibson recognized they were getting cut out of the vintage market and started making not only the reissues (RIs), but also the limited edition copy-of-famous-person's-guitar. What ge

ADHD-haver here. I do the same thing but with music. I created a playlist of albums I've heard hundreds of times. The songs are in album order and when I play the list I play from the start of an album somewhere in that list. It keeps

Oh man, thousands of up votes for a Led Zeppelin reference. This mirrors my experience as a musician. Learning to play gave me the confidence to go into different scenarios and recognize that I had to tolerate being bad first and then I wou

Hire for fire feels like an urban myth. We do a lot of work to find you, interview you, hire you, and train you. Managing someone out is also a lot of work. That being said a company as big as Amazon will always have edge cases.

i think this is too pessimistic. via FBA they've also enabled thousands (hundreds of thousands?) of small businesses and a cottage industry of others that have formed around them.

Not sure what the J was for. Internally it’s been IHM since I joined. “Inventory Health Management” is a backronym. I won’t spill the - albeit boring - beans on where IHM actually comes from.

Flippantly, because hardware is cool! Plugins - software for audio programs - are available but audio engineers are famously persnickety.

I don't have perfect pitch so it's not that I hear a note and see the color it's more like when I think of a note, chord, or mode I see a color in my minds eye. When I'm playing I am aware at a high level the notes I&#x2

Can’t find a reference, but i think it does. I used in the past year for that purpose exactly. Also, checkout typing.io which has lessons based on open source code.

as always, Miley Cyrus is right. I use this mapping in my current setup and find it really useful.

I wrapped my head around the ergodox by realizing that you have to use layers. It's not supposed to map 1:1 with a regular keyboard. I use a modified version of the default symbol layer that's more programmer friendly (I think) an

I disagree. I found the book enlightening as I was experiencing growing pains moving to a more senior role on my team (less time for getting things done, more time helping others, etc) and this book helped me realize that it was to be expec

I’ll have a blog post out in AWS Big Data in a few weeks but the parent is right in that it’s not terribly difficult. Should take about an hour with testing to get a Pyspark script together to read in a DynamoDB table and write it out to S3

This architecture is meant for business intelligence purposes, not for oltp queries. You're right, it would be pretty expensive to power a user facing service this way. However, I read a harrowing / awe-inspring blog post about so

The Lambda is included in the DynamoDB exports CloudFormation templates. It's embedded in the file template itself. Thumbs up on the Glue Dev endpoint. It's been killer. I had trouble setting up a Notebook (I wanted to get fancy w

In general, it's not uncommon for startups of the Goodreads vintage to outgrow a simple Rails app and use a more service oriented architecture. We've actually had services for about 5 years now, but we haven't been very vocal
