I mean, they are completely different. MongoDB is more-or-less a traditional RDBMS with automated failover and trying to staple on more advanced features. Cassandra is a masterless DynamoDB-ish database with features like hinted handoffs. Y

+1 I definitely agree with this. Today there are many strong languages/frameworks that are just as productive or close to as productive as Rails, particularly with more modern languages. I was really impressed by Phoenix when I worked

Was that an argument? It seems pretty clear that that is not the goal of Rails. I'm arguing here that "Rails can't be performant" is not necessarily true

While the phrasing irks me, I think I agree with the sentiment: "languages that value speed tend to expose more of the details, thus when presented with a performance problem, you have more options ready at your disposable". One o

ActiveRecord is configurable. You have options to bypass the serializer. Rails can't magically have the correct answer to every problem out of the box without tweaking "The default behavior is slow!" "Don't use the

Heck, writing this post is enough to be at least a 1.1x dev. I don't subscribe to the whole "x developer" thing, but this is an amazing list

What about running repairs in something like Cassandra? In some cases it is by design. Here I'm a little surprised an airliner would even go that long without a reboot

To be fair, there have also been plenty of times in this situation where the senior dev was wrong. You were right to question things and we should make sure to continue to encourage questions. The difference between a new grad and a senior

Zoom should really come out with a public statement (does one exist?). They've been called out a number of times over the past week or few and I think it would be wise for them to clear up any misconceptions (or hide in a turtle shell

I find it funny that we can find plenty of bread but flour is a completely different story. I'm a little surprised the demand - I recognize how useful flour is, but I'm surprised so many people actually feel confident enough to do

Yes, every year. When your expenses are 7+ figures annually even small scale changes make a big difference. I work for another large company and we have a small change (~2 week effort and ~200 LoC) that is going to save the company $500k-$1

On the other hand, it's just as easy to say "I told you so" and name a thousand factors that we've cried wolf on. We are working on small data and can't draw conclusions despite our human desire to so

I think for most companies the idea is they don't want entire teams getting sick (or worse) at the same time. It's nice to think there's a larger motive at play here, but I strongly believe self-interest is the primary factor

This is what the future of programming languages should look like. Not necessarily syntactically, but with full-fledged systems out of the box. We're not getting further as a community by just building new source code to plug into our

I think this an interesting analogy. Taking it further - what's great about the Home Depot level skills is that they are often sufficient for me to be able to do routine basic maintenance. This is in-part because many things have becom

It's important to say "no" or "we shouldn't be doing this" especially at startups. In my experience many startups hit a brick wall and it's the responsibility of new hires and promos to try and help the co

This feels like a repackaging of ideas that have been around for awhile. I'm not sure I see the value prop of this over stitching together more loosely coupled solutions that have more of a support base. This looks more cohesive overal

To me, clean code is a separate concern from coherent interfaces. Your change changed the interfaces and although I don't have deeper context, I personally prefer the simpler original interface. Have good interfaces first, then use cle

The market for these is hot but I would generally not call it passive. Timing is critical on many cards and offloading them can be nontrivial. I do this lightly as well, mostly for fun
