I ve been doing endurance testing on microSD cards for 2 1/2 years now. I ve gotten coverage in publications such as TechRadar, TechSpot, Tom s Hardware, IGN, and numerous social media posts. I ve destroyed over 150 cards from over 30 different brands and I have over 100 cards from 30 different brands that are going through Continue reading "Dear SanDisk, Please Do Better: An Open Letter"
When it comes to my ongoing project, The Great MicroSD Card Survey, I ve been categorizing my cards into one of three groups: The intent was that name-brand cards would be those cards that came from well-known, reputable manufacturers; off-brand cards would be those cards that came from less well-known manufacturers; and knockoff cards would be Continue reading "What s In A Name?"
On July 27, 2023, I ordered my first batch of microSD cards from AliExpress: three Kioxia Exceria G2 32GB s, a Kodak Ultra Performance 32GB (the gold version), three Hiksemi NEO 8GB s, two Hiksemi NEO 32GB s, three Microdrive 16GB s (yes, the ones with the Bart Simpson design on them), three SanDisk Ultra 32GB s, a Sansumg PRO Continue reading "The Great MicroSD Card Survey: Two Years Later"
It s been exactly one year since I started this project. I ve set up 8 machines with close to 70 card readers running around the clock. I m writing 101 terabytes of data per day. I ve written 18 petabytes of data to 181 microSD cards and destroyed 51 of them. Don t believe me? Check out my graveyard: Continue reading "The Great MicroSD Card Survey: One Year Later"
If you ve been following my microSD Card Survey, you might have noticed that I publish manufacturer IDs for (almost) all of the cards that I ve tested (save a few where they came DOA or where I tested them before I thought to dump the registers off the card). I know that there are other resources Continue reading "SD Card Manufacturer IDs"
Today, I m posting the preliminary results of a project I ve been working on for the last six months now. For lack of a better name, I m calling it The Great microSD Card Survey. Think of it as the answer to such questions as just how good are microSD cards that you buy off of AliExpress? , Continue reading "I m destroying a bunch of microSD cards. For science."
Last updated: 3/28/2025 I get questions a lot about what PayPal users in any given country can do. Admittedly, PayPal doesn t do a very good job of advertising this. But hopefully, I can help shed some light on this. (There used to be a page you could access that would show you what PayPal supported Continue reading "PayPal Country Availability"
Note: tl;dr at the end. I recently came into possession of a Lanier MP C4502 (which is, as far as I can tell, just a re-branded Ricoh Aficio MP C4502). Thank god for government surplus. I have a Macbook that I use for work, and I wanted to see if I could get it to Continue reading "How I got a Ricoh Aficio MP C4502 Working on Mac OS X Mojave"
Update 4/9/2021: Now includes a Python example! PayPal offers the abillity for you to receive webhooks for transaction notifications. This isn t exactly new it was introduced with the REST APIs back in 2013(-ish?). But for those of you still using IPN, you should know that webhooks has some big advantages over IPN. First, webhooks Continue reading "Validating PayPal Webhooks Offline (Almost)"
I originally posted this article to x.com on August 3, 2010. Since that time, x.com has been repurposed, and my posts have been taken down. I have reposted this here for informational and historical purposes. (Updated 8/9/2010 to include recurring_payment_expired) There are several different values for the txn_type variable in an IPN message that are Continue reading "Recurring Payments IPNs"
