This is going to fall into the category of "Dancing Bear" coding in that it isn't how well it works or how elegant it is, it is that it, like the bear, dances at all. Here's the problem. Three code bases that live in: ohi_kafka/experts-all (python) ohi_kafka/loader_reddit_to_kafka (ruby) ohi_kafka/loader_twitter_to_kafka (ruby) And a series of code modules that define array of regular expressions in a constant always named REGEXES th....

Back in November of last year, I linked to an interesting article by Noah Gibbs on how to encourage a blogging culture at your company . Where Noah focused more on the individual, Dan Luu — in How (some) good corporate engineering blogs are written — looks at organizational factors that lead to successful corporate blogs. I encourage giving both a read. As I begin working toward a version of this at work, I found referring to both he..

You know that awful feeling of personal stupidity when you consistently make the same mistake time after time? Well my approach to addressing that is to document said mistakes, here, each time I make them. Sometimes I take the approach of admitting to them and sometimes I take the approach of just writing them as a blog post. There are two errors, nay three, I make almost every single time I create an RDS postgres instance and I though....

I've recently had the situation where my personal development box (OSX Mojave, Rails, Postgres) has become unstable with, at times, multiple crashes per day. I logged in this morning and found myself getting errors like this: PG::ConnectionBad (could not connect to server: No such file or directory) I did some digging and even though Postgres appeared to be running to brew, it was a false positive due to a leftover postmaster.pd fil..

Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it."

NextRoll’s real-time bidding (RTB) platform has been featured several times in this tech blog: we run a fleet of Erlang applications (the bidders) that typically ranges between one and two thousand nodes. As described in past articles , an ongoing goal of the RTB team —as well as a source of interesting technical problems— is to minimize operational costs as much as possible. An obvious way to reduce costs is to make the system more ef....

I noticed an interesting thing yesterday – the number of COVID-19 cases fell in New York and I was curious (the number on the right is the number of new cases). Here's what I saw: What I was curious about was whether this was a reporting issue due to, perhaps, less testing on Sundays or an actual improvement in things. What I realized was that the lack of a day indicator i.e. "Monday" versus 2020/04/06 made this hard. A quick tweak ..

Every year I look back at myself one year back and cringe. So as a gift to my future self, this is a collection of all my current habits I know I’m making a meme out of myself Note taking I take a lot of notes. After trying many apps I’ve settled on Apple Notes. My thinking here is that the standard Notes app is here to stay. Even if I ever go broke I still should still be able to access it.

Please don’t write your documentation in Markdown got a lot of attention last month, when Hillel Wayne said something both reasonable and familiar: Markdown’s simple syntax does not lend itself to complex technical documents. Antonio Zolotukhin made a similar point back in 2018 , as others have before him, and more will in the future. Their argument makes sense; the idea that this is 1) a problem, and 2) needs addressing, however, does..

I'm a fan of Magnar Sveen's multiple cursors Emacs implementation. It's just so fun to use and works very well with commands bound to my favorite keys. Every now and then I'd like to execute extended commands on all cursors, but they have no keys bound to them. If you're an ivy/counsel fan like me (and all packages by Abo Abo ), you use counsel-M-x to invoke commands. However, counsel-M-x doesn't support multiple cursors out of t....

A few weeks ago, I got myself a Bamboo Slate tablet, and had a lot of fun playing around with the output. The Linux software for talking to that device is Tuhi , which is GUI driven, but also dumps the raw point and pressure data in JSON format into a directory. As a side effect of playing around with that, I published a 2d path simplification library which uses the Ramer-Douglas-Peucker algorithm . Given a sequence of 2D points, ....

Go’s lack of generics means that people can’t overengineer in the way they are used to, so they need to put more thought into their designs. There are some use cases where abstractions with generics are better to the current ones (e.g. the sort package), but by and large, in other languages, people use them to build towers of abstractions which you’ll later need to wrap your head around, which introduce conceptual duplication (e.g. mockin..

They would later become the most pivotal company in the technology world, and their co-founder Bill Gates would become the world’s most prolific philanthropist.

The only time I've been able to seriously, rapidly improve my ability to speak a foreign language was through intensive language courses in college. I was forced to actively speak, read, and write Chinese for 6-8 hours a week (1-2 hours every day). Then study another 5-10 hours a week in preparation for the active sessions. I went three semesters like this before I left school. I've been trying to recreate that intensity since and mostly ....
