Nickff - Maybe you could have phrased your response a little differently? Highlighting you had trouble following the OPs post because of all the idioms would have been more effect than demanding they change their approach?
I used Reeder for a year, but switched to Miniflux because I wanted an RSS reader that could be used outside of my Apple devices. I do miss having a mobile app of my reader, since Miniflux can sometimes be hard to navigate on a mobile device. I never seriously considered using multiple readers until now. Thanks for the accidental recommendation.
I don’t think anyone is making that claim. But when it comes down to switching cost + recurring costs, people are starting to answer how sticky are these products.
What’s scummy about this? Seems like the poster was giving a perspective where they are trying to maximize outcomes of the non-profit rather than maximize dollars raised.
I like the idea of having a grid highlighting system, but didn’t see any info on what happens when you have more than 49 unique parts in your current 7x7 grid.
Any plans to allow for multiple unique parts in one cube? And if so, would you prefer to mix like parts with like parts, or mix different part types? i.e. one bin holds multiple types of resistors or one bin holds a unique resistor value and a button
Asking because I’ve tried both approaching when setting up lab spaces, but both systems sort of fall apart without the correct maintenance/tidying_up. Apologies if you answered it in the blog and I just missed it.
Either way, I like the idea of busting out the hammer you know how to use.
This reminded me about an old blogpost I read. This linked post may not be the one I remember, but it's close[1].
Back in 2011 there was an earthquake that New Yorkers felt. There were New Yorkers who read tweets of people further south on the East Coast posting about feeling an earthquake, and then the New Yorkers feeling the same earthquake a few seconds later.
There were some news outlets that picked up the story which you can find, but not exactly what OP was discussing.

When designing hardware, you usually define what the expected operating environments are. Some typical environmental considerations are the min/max temperature, debris ingress, shock & vibration. If you know your product is going to operate in an area where material is likely to enter the product, then you can either try to keep that material out (sealing the product up), or make sure that dust entering the product won't cause failures (i.e. electrical shorts won't happen on a board by covering exposed areas with glue or making sure a mechanism can crush/clear particles). It's not necessarily more complexity in the product to navigate these constrains, but it is another thing to consider in the design.
For example, if you're making a phone that is going to be sold around the world, then you're going to worry about arctic/equator temps (will some of your components melt or ICs fail), salty sea air (will the product begin to corrode for people living by a beach), or fast moving elevators (will the speakers pop from a sudden change in pressure).
You can check out this manufacturers robot arms as some examples of existing products. They list some data sheets for their robot arms, including some arms that are IPxx rated. I don't think looking at robot arms is a 1to1 comparison for what you could expect from a humanoid robot since the considerations in the design process are going to be different.

6 months from announcing rePebble (Jan '25) to shipping your first units (July '25) seems like a quick turnaround for a compact consumer electronics device. Curious to know if these first units are closer to a white label of existing hardware or more of a JDM model.
Side note - I got the first pebble through the kickstarter pre-orders in my first year out of high school. Seeing something so novel was definitely a contributor to me switch from CS to Mech E and working in the consumer electronics space now. Thanks for making cool and interesting things :)
Could another benefit be the ability to change payloads? If there was a desire to change the orbits and payloads, then could these serve a function as a more responsive version of existing satellites?
I recommend a video by Joe Scott[1] that explores this What If scenario. He created renders showing what rings may look like from Earth and from Space. He also went into details such as how seasons may have been impacted, or how the night sky wouldn't be as dark because of the sun's reflections.
This is brining back memories of playing with my older siblings. For the long jump, I would smash the buttons as quick as possible and then my sibling would time (triangle?) to jump before the line....looking back at it they probably just wanted me to do the most tiring task.
Thanks for the rec. I'm going to check out "Human Smoke". Now I want to recommend "Letters from a Self-Made Merchant to His Son"[1] which is a collection of letters that a man, who made his wealth through the Chicago meat industry, to his son who went to college. It gave a warming perspective of a parent who would express his love in one letter, and frustration towards his son for showing up to work late in another. It beautifully illustrates a "modern" parent-child relationship in a time period I often imagine as cold and distant.
You could try a battery powered phone charger since it's a "relatively simple" first project. The big hurdle for learning these types of tools is usually "What buttons do I press to create the output that I want.
For the electrical side, there are plenty of schematics online that you can try to copy or use as a starting point. And the CAD side can be a simple box with snap fits. I'd recommend OnShape if you're just starting out since it's the lowest barrier of entry, but Fusion 360 is also good. All in, it should be <$150 for the PCBs + Components + 3D Prints.
After you get the satisfaction of seeing your device charge from something you made, then you'll start getting the itch and find more excuses to make things.
If you don’t want ti deal with doing the testing yourself, the EPA has a list of certified labs that can test your water for you. If you follow the link, you’ll find Michigan’s cert program and a list of contact info for those labs.
I’ve never done it myself, so I don’t have a sense of how expensive it would be.

The school I went to had a common Dynamics exam. It was considered the first “real” engineering course you took, and was the foundation for a lot of upper div classes. Regardless of your teacher or class time; all students took the same exam at the same time. Professors would grade other professors students.
It was also normal for a double digit % of the students to fail the exam and retake the course (me included).
Its not exactly what people think of as a standardized test, but it ensured all students in the school had the same acceptable level of comprehension on the subject.
Sort of. UL and CE are certifications that declare a a product confirms to the standards defined by those groups. The main difference is that UL only focuses on product safety (i.e. Shock and mechanical hazards), while CE covers product safety plus environmental and health requirements.
UL is technically a global standard, but mostly used in USA/Canada. That's only two countries which already have laws governing what can and cannot be put in a consumer device.
I'm not as familiar with the history of CE, so I don't know why CE decided to cover environmental standards. But my speculation is that it's because CE covers ~30 countries with a larger range of laws.
I appreciate seeing a hint at the history of the design changes, but now I'm left wanting more. Seeing a cross-section view (CT scan or CAD) that shows how the connectors are mating or secured would probably help me visualize how these are being used.
Are you saying that what's happening is the permeability of the cell membrane changes with their physical states (from a scale of "more liquid" to "more solid")and that change impacts the transmission rate of the neurons? And an example of this would be an anesthesiologist putting you under is them making your cell membrane more solid to increase the resistance those neuron transmissions experience, just like adding more resistance to a circuit to reduce the voltage?
Disclaimer that biological sciences aren't my strength so I'm just trying to understand what you're saying.
For Stellaris, one of Paradox’s space 4x games, they have a team dedicated to maintenance and a separate team for DLCs. The result are large free updates that improve/rework on the mechanics which compliment the DLCs keeping the games fresh for years.
Usually the base paradox games feel like they’re “missing” major features which makes some DLCs necessary for a more full experience, but by the time that happens the base game is heavily discounted so base+dlc=full price of a new game.
Just felt like I have to add onto the paradox comment since I enjoy their major updates + dlc approach. Whenever I buy one of their games, I know I’ll probably come back to the game for at least 5 years.
Still had this tab open today (in typical tab hoarding fashion), and saw no one else commented. So just wanted to say thanks for sharing this fun fact. I learned something new, and started going down a rabbit hole yesterday because of you!
Hey Alex, I bought the app a few years ago when I first found the website. Just opened it up for the first time in a while, and saw I can buy the course through the app. But wanted to let you know (in the low chance you aren't aware) that purchasing the course through the app is only $20 instead of $25.
Grade level comprehension is an expectation set by the state. Having some standard to aim for gives us a better understanding of if students are generally regressing or progressing.
We're able to see tread lines over time, and raise alarms like this headline, when we know that students now are not learning as much as students of the past.
I’ve been vaguely following all the AI news on text to image and text that comes out from promos. But I have no idea how a benchmark for text would work. Is benchmarking subjective? Is it based on accuracy of information? How do you actually measure a benchmark for something like this?
I think bag_boy was trying to highlight the tragedy that we can still see direct effects of slavery in the United States, not that it's tragic that descendants of Africans live in America
This feels a bit strange. I remember Codecademy as the first wow moment where I saw items being discussed here also being discussed "in the real world".
You're also reminding me that I've been on here for 10 years.
You could also hit your head after tripping while walking, but people don’t wear helmets on walks. I think the point was that there is a comfortable level of risk people are willing to take. If you remove cars from the equation, then the perceived risk is much lower while biking.
Adding “City Beautiful” to the list of channels if you enjoy “Not Just Bikes”! It talks more generally about city planning/urban design, but satisfies the same itch of content.
Just look at the suicides if you aren't buying it....I won't pretend to know what those officers experienced. But when officers are saying they view the actions of their leaders as disgraceful, and talk about a feeling of abandonment, then just maybe we should believe what they say? Or continue to ignore their complaints.
Anything you say can and will be used against you in a court of law.
They’re explicit in saying how they will use information.
Reading *Golden Gates* by Conor Dougherty right now! If anyone is deciding on a book to read about the history of housing policies, then I recommend it to anyone in California over *The Color of Law* (which is also a great book).
Does a great job of painting how decades of decision making led to this point despite decades of warnings.
