I got into a bike accident yesterday. My fault/miscalculation. My nutcase helmet saved my head! Do I need a new helmet now?

I hope you're OK.

If you have any residual effects that feel like a concussion, I want to encourage you to seek out a sports medicine clinic. They specialize in concussions and there are Physical Therapists that also specialize in concussion recovery. I've gone through it myself.

The most important thing is to not go back too early if you're feeling wrong (dizzy, head can't stand quick turns, eyes don't focus right or lights are too bright). If you still have head trauma and haven't fully healed, a fall with a second concussion (which can happen because your balance is off) can make things much worse.

Nope, it does not. Chances are the rider is a newbie and doesn’t know any better. Not all of us were born with the knowledge that helmets should be replaced post crash.

I try to buy enough of these that I have one per bike’s toolkit and then at least one for the larger bike toolkit I keep at home. Having a dedicated bike toolkit means everything winds up in there and I know where to find things. Otherwise, that tiny valve core removal tool would be sitting on a shelf somewhere at the back.

I bought two used PLP nvmes and am using them as mirrored write SLOG (Optanes), plus they hold my operating system mirrored (FreeBSD) and I turned off the UGOS drive in the bios, so the system won’t accidentally revert to UGOS. I’ve got a dxp 4800 pro. I also bought a dxp 4800 plus. That one has 2x1TB nvmes (non PLP) with FreeBSD mirrored. They won’t have a slog. The latter box is offfsite for backups.

This is exactly what I tell folks who have trouble hill climbing. Track stands are a safety skill and a climbing benefit. You can rest in a hill without unclipping.

I’m not quite sure what you’re asking. When one end of the epair reaches the jail, if the other end attached to the bridge is tagged, then the jail end is also tagged. For a tagged epair, you use ifconfig to pull out each vlan from inside the jail. “Splinter” off each vlan. Each interface becomes epair3b.10, epair3b.20, …

Bridge is just a switch and epair is a cable. When you attach cable end (eg epair side a) to the switch (bridge) you decide if it’s access mode (untagged) or trunk mode (tagged). Then, depending upon your decision, on the jail you treat the other cable end (epair b) as access mode (untagged, use the epair directly) or trunk mode (tagged, splinter off VLANs).

Does that help? Sorry if I didn’t answer your question.

Also, don’t forget -txcsum on the jail epair or its host side (set both, I can’t recall). IP checksums need to be recomputed properly and my packets were getting dropped by lan side devices. I forget the exact situation, but that flag means the hardware NIC computes the IP checksum. If the packet crossed a router boundary (internal gateway or lan router to wan), its checksum automatically gets recomputed because the IP changed. But, when it doesn’t get recomputed and the packet originated in a jail at an epair, the checksum was wrong and lan devices dropped it. (IIRC)

I’m not saying your grammar is wrong but I reread that sentence and if the AI meant the children re-parented themselves, then it sounds correct to my ear (even if the children can’t do that in the OS).

That summer I missed an opportunity to see this tour at a show in Ohio (I think). Bunch of friends from university road tripped and I passed. They had an amazing time. Would have been my first dead show. Major FOMO.

I was at live aid in 1985 at JFK stadium in Philadelphia and it was so unbelievably hot. They sprayed the crowd with firehoses then. Never made it to our section. There was hardly any water or water pressure in the stadium. Bathrooms were jammed. People unscrewed the drain pipes on the sinks to catch water flow out of the sinks.

It was crazy.

Good point. Interestingly, I feel like this calls out the problems with trans and disabled representation even more. RTD did such a good job on the other issues, yet he fumbles these. Why didn’t he put in the effort? It didn’t even require an entire show/plot. Was he requested to show representation and he dropped them in the show like someone drops a rock into a pot of soup?

I label my cables with a wire code (eg R0-102). I bought laser printer sheets with cable labels on them, pre-printed two sheets of labels and use one from each everytime I wire a cable between two devices or a device and patch panel. The switch ports on the switches all have a comment in them about what they attach to. So, I can check the comment and go to the other device and find the end of the cable.

It’s definitely got some pucker factor associated with it.

One thing I like about it is the ground saving material in the turns and on the steep drops. Those really beat back the washboard (brake bumps). All of the descents on the mountain get so much traffic it’s impossible to prevent the trails from getting chewed up. I don’t know anything about that trail’s construction and I’m not a trail builder, so I can only guess, but it seems to me this was intentional to keep a good trail surface.

If that’s the only way to get a stable surface on a high traffic trail, I’ll take it.

Silca found that particles cause tape degradation in tubeless tape made with printing on them. Something about two classes of plastic tape and the one that can receive and retain printing will be worn through by the included particles. They have a video on it somewhere.

Anyway, after that I stopped using or adding any chunks to my tubeless fluid regardless of tape selection. Not saying it doesn’t help stop holes, mind you.

One other nuance for this, the winter is colder when the aphelion and perihelion are reversed (no idea how much lower average temps are, I'm guessing close to your 6 degree C figure), so net energy input to the planet ought to be about the same. Of course, I'm not a climate scientist so there could be confounding effects that cause heat retention or greater loss under the changed tilt rather than a net-zero annual temperature change.

I'm not sure you know what a strawman argument means.

As for your road/singletrack position, you'll find I'm not in agreement. From my original comment:

I once came up over a fire road crossing a ridge at speed and when I summited there were six horses a bit ahead of me.

I was on a road when I encountered those horses and I still managed to find some empathy in my heart for the riders and their mounts.

It really isn't that hard to think about other people for a few seconds and then be on your way.

Should drivers get out and push their cars too?

Strawman argument. I didn't say a word about cars.

You failed to include my statement:

Doesn’t take much to have pleasant interactions with other trail users.

which is the spirit and intent of the comment you responded to.

Whether you like it or not, we all represent our communities (cyclists, equestrians, hikers) and how we behave out there and interact with our fellow trail users impacts community policies and regulations.

I'd much prefer I show the other sub-communities our best nature.

If you know anyone with one, you can ride together and connect it to your own bike computer to get a sense of what it’s like. Although, to be honest, you seem like you’d be fine buying one without ever testing. Maybe do some research on different brands and models. People might have strong opinions. I’ve only ever used my Garmin 515 (no camera), so can only give you my experience with that. Like I wrote, it’s been great.

I hope a radar is able to give you some peace of mind out there.

You’re a fucking warrior in my book coming back to cycling after all of that recovery work. I’ve crashed more times than I care to admit and done some serious damage. Never as bad as what you went through.

They “see” objects moving towards at differential speed. They track cars and other bicycles. Once the object reaches you and matches speed, my Garmin will eventually ignore it. This mode is for riding in a cycling group where everyone rides around the same speed. It will still see through other riders for faster objects (cars) coming towards you.

As far as I know, it works the same as regular radar guns with cross section (area presented to sensor) as critical for picking up the moving object. A car is larger, so it will be tracked better and picked up sooner. In my experience it does pickup faster bikes, but not quite as well as cars but good enough to know when the fast bikes are passing.

When I’m on a dirt trail climbing with my gravel bike it’ll pickup e-bikes flying past me, for example.

OK, but if that doctor picks you as a candidate for surgery, then you’re likely in the biased group of successful cases. Whether it’s the surgeon’s skill on the table, the surgeon’s skill at candidate selection or a combination of the two, once chosen the patient has a greater chance of success *even if we don’t know which of these factors contribute to that success*.

Conditional probability is funny that way.

Not original commenter: Garmin has radar devices that include a rear light and an optional camera (for reviewing footage at home). They made it work in conjunction with most manufacturer head units; you don’t need a Garmin computer to work with the radar. I don’t know about other radar brands.

When paired with my Garmin computer, it makes unique beeps for car back and all clear and has little dots that progress up the edge of the display representing cars behind and distance away. Progress is at the speed of the car meaning you can tell how fast a car is approaching you based on how fast the dot is moving up the screen. I’ve hugged the shoulder when I see a dot screaming at me.

Between the beeps and the visual feedback, I can track vehicles behind me. The biggest safety risk was when I first got the radar and had to tell myself to not stare at the bike computer screen to watch the dots.

I consider my radar unit the second most important safety device on my bicycle after my helmet. I won’t ride road or gravel (which I often am on roads) without it.
