What AI actually multiplies

I wrote earlier about why I’m not buying Jira: a solo user can stand up a custom kanban board with an afternoon of AI help and skip the heavyweight tool. So I did. And the part that stuck with me afterward wasn’t the speed, it was how little of the work was mine, and which part of it was.

The reflex is to call it a ten-times multiplier and move on. But that credits the tool with something that was always mine.

Why I'm not buying Jira

I built a Kanban board from scratch recently. I used a ZazenCodes devtool repo as the skeleton, let Claude Code do most of the typing, and the whole thing came together in a morning before work: a web UI for dragging cards around, an API behind it, a CLI for when I don’t want to open a browser. It fits my head exactly, because I shaped every column to fit my head. And sitting there looking at it, I had the obvious thought. Why would anyone ever buy Jira or Trello?

Why Use Cloudflare Pages Free Tier?

Free plan limits that actually matter for a static blog:

  • 500 builds/month (you’ll use maybe 20-30 if you post regularly)
  • 1 concurrent build, 20-minute timeout (irrelevant for Hugo, which builds in under 2 seconds)
  • 20,000 files per site (you have 10 posts; you’d need to write prolifically for a decade to approach this)
  • 25MB max single file size
  • 100 custom domains per project

In practice, none of these will ever touch you with a personal blog.

Let's Encrypt with Nginx

Let’s Encrypt is a game changer for websites.

I thought it was a good idea when Let’s Encrypt introduced the notion of a free CA Authority making SSL more accessible to the public in early 2015. But, I didn’t delve deeper because I was already using sslmate to somewhat automate my certificate management. Then, as I was setting up a new domain, I noticed that Dreamhost was issuing free SSL for any domain, and I thought, “WHAT?? I want that!”

GPG Key Management

GPG2 is a brilliant encryption tool, but so rarely used.

It’s not used mostly because it’s difficult to get buy-in from all the people with whom you want to securely communicate.

But if you use it and are lucky enough to find peers who use it as well, it’s a great boon for secure private communication and data storage.

Keep Your Master Key Safe

This is a key management technique I learned while working at UC Berkeley: Keep your master signing key away from your working keyring and use it only when you need it.

SSL PFS on Nginx

Update 3/10/2016: Cipher list matches recommendations from https://wiki.mozilla.org/Security/Server_Side_TLS.

Update 5/29/2015: Modified cipher list for high security.

Update 12/9/2014: RC4 has been identified by SSL Labs as a weak point in SSL implementations so the example nginx configuration below now includes disabling of RC4 ciphers. This updated configuration means that the horribly outdated browsers IE6 on Windows XP and IE8 on Windows XP will no longer work with your site.

Also, please upgrade to the latest OpenSSL to ensure that TLS POODLE is mitigated via TLS_FALLBACK_SCSV downgrade attack prevention.

GNU Screen Status Bar

If you live in a terminal, you are likely using GNU Screen.

This is a pretty cool way to set a status bar at the bottom of your unix screen session. Add this to your screenrc file (one line):

[dennis@caffeinatedcode ~]% vim .screenrc

caption always "%{=b dw}:%{-b dw}:%{=b dk}[ %{-b dw}%{-b dg}$USER%{-b dw}@%{-b dg}%H %{=b dk}] [ %= %?%{-b dg}%-Lw%?%{+b dk}(%{+b dw}%n:%t%{+b dk})%?(%u)%?%{-b dw}%?%{-b dg}%+Lw%? %{=b dk}]%{-b dw}:%{+b dw}:"

Online Backups for the Truly Paranoid

I like paranoia in design. Well, I take that back. I don’t like it when it inhibits programming experimentation and creativity, but I do like it when it comes to services, and most especially when it comes to backup.

I wanted to write about my experiences with consumer offsite backup services (e.g. Mozy, Carbonite, Jungle Disk) as well as the plain practice of having a redundant storage device onsite. But all that was side-tracked when I recently needed to quickly backup my servers, and discovered tarsnap.
