I did a survey of the cost of buying hard drives (of all sorts), microsd/sd, USB sticks, CDs, DVDs, Blu-rays, and tape media (for tape drives).

I excluded used/refurbished options. Multi-packs (5 USB sticks) were excluded, except for optical media like CD-ROMs. Seagate drives were excluded because Seagate has a poor reputation.

Per TB, the options are (from cheapest to most expensive):

• Tape media (LTO-8) at $4.52/TB, but I recommend against it. A tape drive is about $1,600 (twice that new). That’s a breakeven at 150-300TB. Also, the world is down to one tape drive manufacturer, so you may end up screwed in the future.
• 3.5″ internal spinning hard drives, at $15.00/TB. Currently the best option is 8TB drives.
• Optical media, at $16.71/TB. 25GB blu-ray disks are cheapest.
• 3.5″ external hard drives, at $17.75/TB. Currently the best option is 18TB drives.

• 2.5″ portable spinning hard drives, at $22.00/TB. Currently the best option is 5TB drives.

• SSD drives, at $42-$46/TB. Best option is 1TB.

• USB sticks, at $59/TB. Best option is 128GB sticks.
• MicroSD cards, at $62/TB. Best option is 512GB cards.

Changes since the last survey (4 months ago):

• Amazon’s search improved. Less refurbished drives and sponsored listings.
• Spinning drives: 22TB 3.5″ drives became available
• Spinning drives: Prices for the previous cheapest option (4TB) rose, making 8TB the new cheap option.
• SSDs: Prices dropped by about 30%.
• MicroSD/SD: Prices dropped slightly.
• Optical: The cheapest option (25GB blu-ray) dropped 30%.
• Optical: I stopped gathering data on the cost of BR-RE
• Tape: LTO-7 tape drives are now available used, halving the break-even point on tape.

It’s no longer november, but I’m still doing a project a day. It’s an all-month hack-a-thon!

Yesterday’s project was Hack-A-TV-Guide (demo, source). It’s a TV Guide generated from Wikipedia. I got the idea from having written isrickandmortyout.com. Why not do the same thing, but for every show?

I’m going to call this one a flop. There’s a good version of this project, but I ran out of time. Basically all it does is display info about a show, which is not very useful.

Today’s project is Hack-An-Uptime (demo, source). It’s a simple experiment where you press a button every day.

This was a very simple project. I’m curious what will happen with it.

I’m continuing Hack-A-Day, I think. Today’s project is Hack-A-Bug (demo, source). It’s a bug reporter I can add with one line to any of my projects.

It’s november, and I’ve decided this month that I’m going to do 30 projects in 30 days. It’s an all-month hack-a-thon!

This is November 30th, so this will be the last project.

Today’s project is Hack-An-MMO (demo, source). It’s a small collaborative art RPG. You can draw people, places, and things to populate the tiny world. Have fun!

Today’s project is Hack-An-Adventure (demo, source). It’s a coloring book. It’s designed to be relaxing.

Today’s project is Hack-A-Farm (demo, source). It’s a simple tile-based RPG. You can walk around as a chicken, admire your house, and plant and harvest two types of crops.

My main goal with this project was to work with spritesheets or animation before, which I had never done. Showing off the individual tiles is deliberate. Also, the game should respond well to smaller and larger screens, I hope.

I had a good time with this one, and I’m happy with how much I got done in a day. I originally planned to do more fluid walking (it was called Hack-A-Walk), but it was more fun to add crops instead.

I re-used some of the logic from Hack-A-Minigame and Hack-A-Snake. I’ve been finding d3 to be mildly useful, if a little annoying.

Today’s project is Hack-A-Snake (demo, source). Yesterday I wrote a game where an AI plays snake. Today I thought, hey, I should release that with keyboard controls so people can just play Snake.

Today’s project is Hack-A-Minigame (demo, source). It’s the classic Snake, but the twist is you can only save and load the game. Rather than controlling the snake, it moves at random under AI control. You have to repeatedly save and load to make progress.

Credit to Jeff Lait’s “Save Scummer” 7-day roguelike for inspiration. Although actually, this whole minigame is mostly for a future project!

Today’s project was Hack-An-Experiment (demo, source). It’s designed to present the basics of experimental algorithmics, while also getting me acquainted with d3.

I have to say, I keep seeing d3 sold as a “graphing” library. And it’s definitely not. Maybe you could write one on top of it.
