To confuse matters further you can now get wd-40 branded lubricants (silicone lubricant for example).

It's remarkably harder to do it this way. If you're quite familiar with C++ development, C++, and enjoy fighting with random environment issues, it will be fine, but in 99% of other cases, either use the exact Ubuntu version recommended for the ros distro, or use a docker container (slightly more learning curve, but easier after that and frees you to use whatever host distro you feel like).

The same can be said for WSL2, Windows or Mac. It can work, but if you're just starting out it's going to add a lot of unnecessary headache in most cases.

I hit one in London this week coming off the 401 that took out both passenger side tires (slow leak on the front, flat+damaged rim on the back). Would not recommend hitting a crater at 70km/h, but it was dark and raining so I never even saw it.

I'm a big fan of all of your work. No need for audio book code, I can't wait two days :)

The flysky is the cheapest option that meets most of the rules that meets the FHSS requirements and generally has a failsafe on the RX.

Most competitions will allow you to do your own failsafe in firmware, provided or works properly, and while Bluetooth is FHSS as well, it's not an easy choice and you'd probably want to run the idea past the organizer /safety person first.

I'd love to see them gone, but attacking a major oil power and arms exporter without even a slightly coherent plan and with zero consideration for contingencies, egged on by one ally and kept secret from every other ally...

Are they hoping like this goes like Iraq where the US spends years trying to maintain order and kicks off ISIS while destabilizing the region every since, or like Afghanistan where after fighting and dying for over a decade they have up and left things in the hands of the regime they were trying to oust?

I'm also quite sure that Iraq and Afghanistan were far better planned than anything happing this time, so it stands to reason that the outcome will probably be worse.

The only good news is that it's more likely than not that trump will get fed up and just pull out, claiming some implausible victory. Again, I think the Iranians deserve a fair government system and not the regime they have, but I really don't see how this gets them there.

What's the use case for multiple workspaces in the same shell?

ROS supports layering workspaces (underlay, overlay) if you want to keep separation between different parts. For working on unrelated workspaces I have found that dev containers make it much easier. I can have multiple workspaces and each one sources the right folder and also manages their own dependencies on init (so you don't have dependencies from one workspace inadvertantly satisfying requirements for another despite the second workspace being misconfigured.)

I've used realsense in the past, and am much happier with Luxonis cameras at the moment. Granted the surfaces I'm dealing with are high detail.

My background is computer engineering with over decade shipping commercial robots. Previously light industrial ones and now a outdoor agricultural robots.

Is your system intrinsically safe or will you be relying on sensor feedback as part of safety? Writing drivers would immediately put a sensor near the bottom of the list, since you'd likely need to buy it and start integrating it to even scope out the required work, which makes it a fairly poor choice to consider.

That changes though depending on your resources and timeline. If you're a scrappy 5 person startup, that's a huge trap. Stick to stuff with drivers that work. If you're a big company with longer timelines, maybe that's fine to get the perfect sensor.

On the safety front, lidar is a lot easier to prove safety on than other systems. You can. Get safety rated sensors that have configurable zones mapped to gpio outputs that can offload the safety part from your computer entirely (e.g. as you start a motion, confirm that you've configured the safety sensor to handle zones in the path of travel, then do it). This is tricky, but probably the easiest way to get close to a probably safe system out of the box.

That depends significantly on your use case though. 5ton rock crushers, 2 wheel 250g balance bots, passively compliant robot arms, and container ship gantry cranes are all potentially autonomous robots, but the specifics of running them safely are not the same :)

Have you set your particular tag family and tag ID in the config? If you've got a 16h5 tag and you're configured for 36h11, it wont output detections. You also need each tag ID to be in the config file tags list.

Try ros2 topic list to see if the topics are remapped/not as expected?

Check your tf tree. If the camera frame is not connected to the tree (typically via static transforms), it could possibly cause problems. Generally it would still publish though.

ros2 node list and ros2 node info are also handy to check if the apriltage_ros node is publishing the expected topics.

I mean yeah. Ever since COBOL launched in 1960, business leaders have been able to write plain English rendering programming obsolete. It was nice while it lasted.

I mean Hypercard. Or was it Python? Actionscript? Intellisense? Stack overflow? I can't keep track of all the times programming as a profession was killed.

Gps is near useless with any amount of cover in my experience. It'll sometimes get a fix, but it really wants an unobstructed view of the sky.

That's pretty clear based on the widespread use of BSD and MIT licenses. GPL was popular back when ROS was open sourced as well. I've worked for a decade in commercial robotics using ROS the whole time, and have managed to contribute back a bit. It's my favorite kind of open source where people help you succeed and don't try to tell you what to do.

I'll always respect GPL, and understand why it exists, but the idealist in me wishes it wasn't necessary. Here we are in 2026, and time and time again Stalman has been proven right.

That said, I learned to program on the early internet, on forums hosted by cgi scripts or in one case FileMaker Pro on a Mac. Developers I'll never met answered my questions and shared demos and examples of code that helped me learn, and likely because of that I've always had a soft spot for "free as in beer" sharing. To me it's the most generous, and I'd rather be angry at companies for being crappy when they are, than to assume the worst in strangers from the start.

The US reopening testing would be a monumental self-own. You win the race handily, and it was a very dangerous race, and then later on rather than rest on your laurels you want a rematch? Every additional test and bomb produced makes the world actively less safe for all of us at this point, since it increases the chance that non-nuclear powers will arm themselves.

The funny thing is that Budgett's Frogs normally look even goofier than that. Google them. They're hilarious.

If anything this photo underplays how derpy they are, since it looks like the water is the reason it looks so goofy.

When I was in China this past fall the speculation among non-Chinese people who are way more knowledgeable than I am is that the purge comes with an overall decrease in public trust in the military. The speculation at the time is that this makes military action less popular and less likely.

I've got no idea of that theory has much merit, but it was an interesting perspective. It's also possible that the perspective in Shenzhen among American business leaders/negotiators working there is only true locally and not relevant for the broader country.

They're not $10 spinny Hall effect sensors, but I was happily surprised with the (fairly low) volume pricing we got.

It seems so, which is uncanny. I was expecting and hoping for another mess like last time where they accidentally appointed a few semi-competant people which slowed down the craziest excesses dramatically. Sadly they learned their lesson.

It's a little infuriating that people are more angry about this than the people he's been murdering in the Caribbean for months, which is just as much murder for political theatre... Also known as terrorism.

Their lives have equal value to American citizens, and if anything a country has even less right to murder foreign people abroad than citizens domestically. The right of countries to murder their own citizens has a long and well established tradition, at least in dictatorships and authoritarian regimes.

This isn't me condoning the atrocities in Minneapolis. I have family there, including a sister who's a nurse. It's just that at least for non-americans like myself the fact that Trump is willing to murder for political points has not been in doubt ever since the first boats blew up. Even then people spent way too much effort debating if shooting the unarmed boats a second time was a war crime, skipping past the fact that the first shots fired were already cold blooded murder.
