A company’s logo should be evocative of their strengths. So suggesting they, principally, shit all over everything is apt.



8 Million Requests Later, We Made The SolarWinds Supply Chain Attack Look Amateur
Alt Title: How to take over the world using abandoned S3 Buckets Watchtowr has moved on from using expired domains to assume authority over entire TLDs and instead is using blind trust in S3 addresses to infiltrate governments and militaries across the world. > The TL;DR is that this time, we ended up discovering ~150 Amazon S3 buckets that had previously been used across commercial and open source software products, governments, and infrastructure deployment/update pipelines - and then abandoned. > As for the research itself, it panned out progressively, with S3 buckets registered as they were discovered. It went rather quickly from “Haha, we could put our logo on this website” to “Uhhh, .mil, we should probably speak to someone”. > These S3 buckets received more than 8 million HTTP requests over a 2 month period for all sorts of things - > > - Software updates, > - Pre-compiled (unsigned!) Windows, Linux and macOS binaries, > - Virtual machine images (?!), > - JavaScript files...

When I I’ve exhausted my Subscribed (HOT) and All (Top 12 Hours) Lemmy feeds but still have the desire to scroll, I usually head over to Printables to look at 3D prints for a while… see what my printer will be doing for the next week. I really like the filtering options that model site has. Less often I’ll do the same on MyMiniFactory


Sure.

I’m about to design a new ceiling lamp nut for our kitchen, because the original has gone missing after a light bulb change. I’ll use a spare metal nut then print a cover to go on it so it looks intentional.


Because experts usually know their worth and charge accordingly.


A Flipper Zero. I probably have the components to make something functionally equivalent, but that form factor, all-in-one nature, and simple UI look nice.

I have no need for it, I just want to tinker.


Fixing and adapting things around the house is what I like most about having a 3d printer.

I’m pretty sure the first printer is now paid for itself by doing that. Just because of things I haven’t had to pay to replace. As of this summer I’m up to 3 printers and I can’t claim I’ve paid for all 3.


I’d change “I” to “pxmipexokal” just to screw over everyone’s typing speed.


That the air will clear so I can spend the holiday weekend outside my house.



I learned how to but haven’t been behind the wheel of a manual transmission car since the 90s.

In my family you couldn’t get a drivers license until you know to drive any car and also the basics of maintenance. Other things I have’t done since (roughly) the 90s: change my oil/coolant/brake/transmission, change various filters, replace pump seals, or replace hoses/belts. But I have to admit, its handy to know how to do all that.


My next step is custom boards and smds, and an oscilloscope seems like a good way to diagnose when reflow goes wrong. I already have had some fights with I2C using dev boards. But really I’m eyeing one because I have allusions about doing fine calibration on analog sensors.

I should add that I’ve been talking myself out of an oscilloscope for 2+ years now. I don’t REALLY need one.


Mine is pretty basic but is built on the shoulders of giants. Also that $20 was from pre-pandemic / pre-chip shortage prices. I’m guessing it’s more like $35 now, or maybe high $20s from ali express.

I use Home Assistant for home automation. It has a now official addon called ESPHome for easily configuring esp devices and adding them to Home Assistant.

I bought some cheap dev boards off amazon and thankfully they worked
    an esp8266 microcontroller with IC2 headers and a microusb port already onboard
    a bmp280 that measures temp, humidity, and barometric pressure
    a lux sensor with a plastic dome over the top
I soldered them together on a prototyping board

All the components were supported by esphome, so I just needed to write the device config and then flash the devboard via esphome (in a web browser) over the built in usb.

I 3d printed a housing for it, but you can also buy boxes. It needs airflow but also needs to stay dry. You can use a spray sealant to help avoid corrosion from ambient humidity. I skipped that step because I want to see how quickly it becomes problematic… and I should probably check on that.





Electronics / microcontrollers.

Took just a few months to go from, “I can make a wifi connected weather station for like $20 in components!?” to “oscilloscopes cost how much?”


I read most of the DOS 6.0 manual around 1994. This was the era of memory management. Computers had 640k of conventional memory despite my PC having 4M of total ram. Every TSR you could extract out to high or extended memory would have a massive impact on the performance of high demand applications (like all my important applications from Lucas Arts…). I managed to get mouse, soundcard, video, and other drivers loaded and still have 580+K of free conventional memory.

Now I design web scale server architectures capable of handling hundreds of requests per second with five 9’s of uptime (for a few years anyway), and that memory management, from back when I was a tween, is still one of my proudest technological achievements. Thanks DOS manual!
