A non-comprehensive list of bugs with NETGEAR ReadySHARE
  • ReadySHARE only supports drives up to 4TB in size. Some routers have an even smaller limit.
  • If you are using a drive with multiple partitions, ReadySHARE can, between firmware upgrades (or maybe reboots?) switch which partition is presented in which Samba folder.
  • ReadySHARE seems to change the mount point / "share name" of attached devices based on the the current phase of the moon.

Multi-stage Dockerfiles with perl and perl-slim

The benefits of using multi-stage Docker builds is well-known. Using multi-stage builds with a pure Perl setup is trivial -- all it involves is copying the /usr/local/lib/perl5 directory:

FROM perl:5.28 as builder
COPY cpanfile cpanfile
RUN cpanm --installdeps .

Tips for working with s3cmd on

Working with s3cmd on

This document lists some problems I encountered using s3cmd on and how I solved them.

Uploading with the ONEZONE_IA class

s3cmd sync doesn't support the --storage-class argument, and even that doesn't support the ONEZONE_IA storage class. You can still upload objects to that class by specifying the x-amz-storage-class header, but s3cmd sync will ignore that. The best solution I have is to upload your files as you normally would, then use s3cmd modify to set the storage class after upload.

Tracking recurring reminders

I use my Fastmail calendar to track recurring reminders, like regular maintenance, or scheduling a doctor's appointment, or requesting a credit report, etc. I create each reminder as an all-day event on a calendar only for reminders, and configure each event to send me an email reminder on the day of the event.

This approach is simple and flexible:

  • Recurrence rules make it trivial to configure a task to repeat at any interval, whether it be on the nth day of the month every m months, or every other year, etc.
  • With an Inbox Zero approach, reminders stay out of the way until they're relevant, and can be

Warning about Vanilla eGift Cards

If you receive a Vanilla eGift Card, you should know that the link to the page with your eGift card details will expire after some weeks. The link can supposedly be reissued, but it must be requested by the person who purchased you the eGift card over the phone. So, best to save the card details somewhere once you receive them.

The eGift Card funds are advertised as never expiring. It's not clear to me if that guarantee holds for funds left inactive for a long period of time.

Guide to the Defined Contribution Plan for UCSC undergraduates

Guide to the Defined Contribution Plan for UCSC undergraduates

First, a disclaimer: I am neither a lawyer nor a financial adviser, and if I were, I wouldn't be your lawyer or financial adviser. This is neither financial advice nor legal advice. I didn't even study this stuff.

That said, I've provided sources where appropriate. In particular, I'll refer to these documents:
