Career Path: Undefined — Rails Developer T-Shirt
Career Path: Undefined — Rails Developer T-Shirt
Fifteen years of Rails, and the method everyone expected still isn’t defined. A two-sided developer tee for those turning a long debugging career into the next build.
Made to order. Please confirm your size and colour before purchasing; we can’t accept returns or exchanges for selection changes.
Best fit check: measure a T-shirt you already own and compare it with ./size-guide below.
./size-guide
Regular unisex fit. Choose your usual size for a standard fit, or size up for a more relaxed fit.
| size | fits chest (in / cm) | length (in / cm) | sleeve (in / cm) |
|---|---|---|---|
| S | 31–34 / 78.7–86.4 | 28⅜ / 72 | 9¼ / 23.5 |
| M | 35–38 / 89–96.5 | 29⅛ / 74 | 9½ / 24 |
| L | 39–41 / 99–104.1 | 29⅞ / 76 | 9⅝ / 24.5 |
| XL | 42–45 / 106.7–114.3 | 31⅛ / 79 | 9⅞ / 25 |
chest = wearer’s chest circumference. length = highest shoulder point to bottom hem. For the best comparison, measure a tee you already own. Measurements may vary slightly.
./shipping-delivery
Each shirt is made to order. Please allow 2–5 business days for production before it ships.
Typical carrier transit after production is 3–5 business days to the United States, 5–8 to Canada, and 7–14 to Japan. These are estimates, not guarantees.
Standard shipping is free on merchandise orders of C$99 or more. For a one-shirt order, the current flat rate is C$8.59 to Canada; the United States and Japan use a C$4.95 base rate, converted to the market currency at checkout. Final rates are shown at checkout, and split shipments may differ. Tracking is emailed when your order ships.
./returns-exchanges
Because every shirt is made to order, returns or exchanges are not accepted for buyer’s remorse, an incorrect size, or an incorrect colour. Please check the size guide before ordering.
If an item arrives damaged, defective, or misprinted—or your package appears lost—contact us within 30 days of delivery or the estimated delivery date. Eligible issues receive a free reshipment or refund.

After 15 years of building Rails applications, some methods remain stubbornly undefined.
The back print recreates a familiar Rails console session: an experienced Engineer, fifteen years in the framework, and one missing full_time_job. Ruby raises the inevitable NoMethodError before offering a more promising suggestion:
