Since this is HN, I'm gonna pick a nit. > A clever and witty bash script running on a unix server somewhere is also not utilitarian coding, no human ever directly benefited from it. Back around 2010, my friend Mat was doing cloud co

If you are good enough at the task of "finding a cofounder" that you can offer useful advice on it, you are... bad at some very critical things. This is not a task anyone should be experienced enough to be good at.

I saw a headline about the book on Reddit and made a joke to a friend of mine: "How much you wanna bet it uses mmap?" Well... It uses mmap.

Because employers _want_ people to be fungible. The quest to quantify and systematize hiring is a Quixotic effort at solving real challenges, but it persists because nobody has come up with an actual solution.

Almost, but not quite the audience for your question. I was going to use Heroku, but the security requirements for my app made that a non-option. Instead, I went with simple Terraform that spins up CoreOS nodes, using cloud-init to spin up

My home folder is a git repo (with a very extensive .gitignore, so I'm only versioning dotfiles, ~/bin, etc), with a branch per machine. Copying over the .git folder to a new machine is step 1. From there, I selectively restore

Rails + graphql-ruby + ActiveAdmin + Devise + SideKiq/Faktory + Postgres remains a ridiculously productive combination for me. I'm leaning more towards Faktory these days because it makes it possible to move individual jobs from R

The workaround I've found: Select the relevant line(s), but before releasing the mouse button, cmd-c (or the equivalent shortcut in your local computing environment). But yes, it's incredibly annoying. Especially for those of us

As I touched on, the cost can vary a lot depending on the particulars of the situation. For example, one company I came into was using Redshift and fighting a lot of problems with it. The problems stemmed from a combination of not knowing

Well, for starters, it's simply untrue that every company (likely) will (barring bankruptcy of course) eventually need extreme scale, and the implicit assumption that the up-front cost of implementing such scalability is necessarily wo

I think you're crossing the streams a bit here. Twitter designed _Snow_flake. _Sony_flake is a reimplementation that changes the allocation of bits, and the author acknowledges that the maximum ID generation throughput ceiling is low

I suspect the surrounding context is Apple threatening to yank the Hey app for bypassing Apple's cut by not using IAPs for managing subscriptions.

What you're doing by keeping up to date continuously is reducing the cost of a major version bump down the road -- should that become required. For example: If you had a Rails 3 app, and you updated to Rails 4 when Rails 4 came out, t

I've never quite gotten the hang of `git add -p`, so I use `git gui` (incl. with Homebrew version of git, among others), or other tools that let me do partial staging/unstaging via line-selection with a mouse. It's a handy w

It's just serialization as a workflow mechanism, and it really gets rid of a lot of workflow cliffs. It's also nothing to be afraid of: You can absolutely do everything programmatically, using the same (mostly-public) APIs that t

Octopress, which is built on Jekyll. Unfortunately I bet on Octopress waaaay back in the day when it was essentially a very customized Jekyll install. This has led to a situation where updating to a newer release of Octopress, or even upg

Just saw your question on a thread from a couple weeks ago about building a TD game. As I'm only now seeing it, I apparently can't respond directly anymore. Email me -- jfrisby at MrJoy dot com and I'll be happy to offer so

I've now worked at two companies in that space -- a startup I cofounder in 97, and a much later-stage startup I recently joined -- and all I can say is... shrug The company I'm currently at is certainly making things better for

i suspect that even without the ridiculous hoops, the incompetent will always spend a disproportionate percentage of their time job hunting, and thus making the hiring process challenging.

by jfrisby 10y ago
It's a combination of two things: 1. We're bad at hiring, as an industry. We just aren't very good at identifying good candidates. 2. We're an industry where the average skill level is below the minimum threshold of com

I had a chance to ship the first Tower Defense game for iOS. The OS X game I was porting had some crippling performance problems that were incredibly hard to track down. The problem was two-fold: 1. The relevant tools (Unity3D) were extrem

Nobody who works on safety-critical systems is an idiot incapable of imagining or caring about the consequences of their errors. Your ignorant, fact-free fear-mongering is antithetical to saving lives. 1. An immense number of lives are bein

I have empathy for the ~33,000 people that die every year because humans are terrible drivers. You do not. You want to take a moral posture that condemns thousands of people to needless deaths because you're so caught up in emotion yo

Except that the car wasn't autonomous here. The human behind the wheel had been explicitly instructed to keep hands on the wheel and feet on the pedals -- and that it was his responsibility to override the machine's judgement if c
