Around the turn of the century there was an ambient music transmission called Blue Mars.

It and Rant Radio Industrial were important sources of music in the early days of streaming. Blue Mars described itself as Music for the Space Traveller:

Long ago, when the waters of Mars were still under the ground and above the sky, our ancestors came to this place and called it “Home”. And from the high Plains of Tharsis to the Elysium Ocean, from as high as Mount Olympus to as deep as the floor of the Hellas sea, one can still hear the song of our brothers and sisters chanting to us throughout the ages.

This melody is one that is made of hopes… It is sang with the voice of nostalgia, and looks ahead with pride. Listen…

The transmission ceased some years ago. For a time, recordings of the stream were rebroadcast at a site called Echoes of Blue Mars, but that too seems to have come to an end. Recently I stumbled across someone who had created YouTube playlists of much of the original music.

There are also playlists for Blue Mars’ two alternative stations. Cryosleep, which was described:

Most people who underwent cryosleep have reported that the mind seems to naturally retreat into a place of infinite tranquility, where the experience of Time itself is distorted in a subtle way.

Although there is no trace of conscious activity in the brain of sleepers, it appears that Experience itself never ceases, creating atemporals bubbles of memories of transcendental calm when the subject awakes.

It may be possible that chemicals used in the cryosleep process alter the outer cortex in a way that is not yet understood, however we believe cryosleep is a perfectly safe means of interstellar travel.

And Voices from Within, explained:

In these days of stellar explorations, encountering alien lifeforms is the dream of many space-travellers, but Language will always hinder the realization of the full potential of such an event.

Thus, Voices from Within tries to prepare cosmonauts for the experience by focusing on the abandonment of Words in favor of Vibrations, which, being uniquely suited to channel your Emotions, will usher Comprehension into the Mind of your new alien friends.

Luer Lock Lubing

Earlier this year I purchased the Occam Lube DIY Kit from Occam Defense. This is a simple but ingenious solution for carrying and applying oil and grease by utilizing the Luer lock system from the medical industry. I shoot tupperware that runs dirty, and I have not travelled enough with firearms to need to think about lubricating them away from home, but I have needed to pack chain lube for my bike on longer tours. In the past I’ve been disappointed by the bottles of both bicycle and firearm lubricant, which may either leak or make it difficult to apply the contents precisely. There’s nothing in the Occam kit that you couldn’t put together yourself, but it is very reasonably priced and I credit it with being my introduction to the idea of using Luer components for lubrication. As soon as I stumbled upon the kit I purchased it.

The Occam kit includes one 30ml Luer syringe, three 3ml Luer syringes, three 22 gauge Luer dispensing tips, three 14 gauge Luer dispensing tips, four Luer caps, and a Luer gender adapter. Oil is drawn up into the large syringe, which is then attached to one of the smaller syringes via the gender adapter. If using grease, the grease is simply packed into the large syringe after removing the plunger, and then pushed into one of the smaller syringes. About 1.5ml of oil (or grease) may be pushed into the small syringe from the large syringe. The remaining 1.5ml of space inside the small syringe is needed to store one of the dispensing tips and the plunger cap. The intent is for the filled, smaller syringes to be placed in various kits and be taken on the road, giving you the ability to store the oil in a leak-proof manner and dispense of small amounts of it in precise areas. For applications where you need very little lubrication, like firearms, this works great.

I had never given much attention to what volume of oil I use when lubricating a bike chain, so I wasn’t sure if the smaller syringes would really be useful for this application. I’ve always been a one-drop-per-roller kind of guy, which I think results in the best lubrication with the least amount of waste. With my current oil of choice, I find that I use a bit over 3ml of oil when servicing my chain. When one of the dispensing tips is stored in the small syringe, the remaining 1.5ml capacity won’t work for me. But I can store the dispending tip separately, fill up the entire 3ml with oil, and still have a very compact, lightweight, and leak-proof option for lubricating on the go.

As happy as this makes me, I admit that carrying lube on a bike isn’t the most pressing concern. Good oil lasts, so unless you’re putting on a lot of miles in challenging conditions, you probably won’t find yourself needing to drop oil away from home. However, I have found that the Luer system is useful even at home, with a few additional purchases to supplement the contents of the Occam kit.

I purchased Luer lock bottle caps for 15-415 threading, 24-410 threading, and 20-410 threading. Between these three sets of caps I can convert most existing lube bottles to the Luer system. If I come across an oil in a bottle with some other type of threading (as is the case with Boeshield T-9), I transfer it into an appropriately sized bottle with standard threading.

I also purchased a few additional dispensing tips (the angled ones are nice), and a package of syringe tip caps to make the lids leak-proof when no dispensing tip is attached.

I can now be sure that none of my oils will leak, which is important to me whether the bottle is in a bag or a toolbox. Using a Luer gender adapter, I can easily transfer oil to a smaller travel sized container, be it one of the Occam syringes or simply a 0.5 oz bottle, or any other Luer-compatible container. Using a dispensing tip, I can accurately deposit precise amounts of lubricant, eliminating waste.

All of this is entirely unnecessary, but I find that small improvements in efficiency like this do translate to a higher quality of life. If you ever find yourself dispensing small amounts of a liquid, and you have a personality that values accuracy and precision (and tidiness), I’d definitely recommend picking up an assortment of Luer components. The Occam Lube DIY Kit is a great place to start.

Old bar tape can be used to wrap various hand tools.

A few weeks ago I installed a new set of handlebars. My old tape was cut too short for the new bars, so I had to replace it. I used the old tape to improve the grip and padding of a hammer, chain whip, and breacher bar.

I use Blokada to reduce the amount of advertisements on my telephone.

Blokada registers itself as a VPN service on the phone so that it can intercept all network traffic. It then downloads filter lists to route the domains of known advertisers, trackers, etc to a black hole, exactly like what I do on my real computer with hostsctl. For me it has had no noticeable impact on battery life. I have found it especially useful when travelling internationally and purchasing cellular plans with small data caps. The only disadvantage I have found is that Blokada must be disabled when I want to connect to a real VPN via WireGuard or OpenVPN.

Blokada must be installed via F-Droid (or directly through the APK) because Google frowns upon blocking advertisements (but at least Google allows you to install software on your telephone outside of their walled garden, unlike their competitor).

Last year I bought a set of Orfos Pro lights.

The Orfos Pro is a simple and flexible LED light that is powered by a separate USB battery. I use the white light model as my bike headlight. This means that, when not in use, the light has a male USB Type-A plug hanging off the bike. In inclement conditions I usually want light, so I’ll have the connector inserted into a battery. I haven’t been too worried about protecting the plug when not in use. Over the past 14 months I haven’t noticed any problems. But when I saw the CozyCaps USB Caps I decided they would be a worthwhile addition to the setup. I expect they will do a good job of protecting the connectors from dirt or light moisture.

I power the headlight with an Anker PowerCore 5000, which mounts to the down tube via a Twofish Bikeblock.

Sof Sole Athlete Performance Insoles

Last year I mentioned replacing the insoles in the Altama OTB Boots with Ortholite Fusion Insoles. The Ortholite insoles fit well in the OTB boots, and make the footwear zero-drop (or at least close enough to it that I can’t tell the difference). It is a lower volume insole that Altama’s default rubber one, and so requires tighter lacing. Unfortunately, the availability of this insole appears to be limited. I’ve also decided that it is a little too soft for my taste. I like a firm footbed. The Ortholite Fusion, while thin, allows my foot to sink into it slightly more than I would prefer.

When I bought my ranger green OTB boots earlier this year I could not find the Ortholite Fusion insoles in stock in my size. So I went looking for alternatives and ended up with the Sof Sole Athlete Performance Insoles. I bought mine from The Insole Store. I mention this because The Insole Store actually provides measurements for heel thickness, forefoot thickness, and arch height. This is critical information for making an informed purchase of an insole, and yet very few retailers or manufacturers provide it. The Insole Store also supports filtering by characteristics, such as walking and running insoles without arch support, which makes it easy to narrow down the wide array of options. This kind of stuff seems like it would be common sense for anyone selling footwear, but it isn’t, so I give my money to The Insole Store.

The measurements provided by The Insole Store for the Sof Sole Athlete Performance Insoles are:

Thickness at heel: 7.75m
Thickness at forefoot: 4.6mm
Arch height: 20mm

I’m happy with anything up to a 4mm drop. These have a 3.15mm drop, which is close enough to zero that I can barely tell the difference. I wasn’t sure about the 20mm arch height. That’s a 12.25mm climb up from the heel, which sounded high, but I ordered the insole anyway. When wearing them, I don’t notice any rise in the arch. They feel flat, which is what I want.

It’s interesting to compare these Sof Sole insoles to something like the Superfeet Carbon Insoles. This is what Superfeet markets for low-volume, minimalist athletic footwear.

Thickness at heel: 5.5mm
Thickness at forefoot: 2.75
Arch height: 30mm

The heel and forefoot numbers are great. Nice and thin, with only a 2.75mm drop. But the 24.5mm climb from the heel to the arch is ridiculous. I tried a pair of these once, and it feel like standing on a golf ball.

I’ve been very happy with the Sof Sole Athlete Performance Insoles. I ended up buying a second pair. They are trim-to-fit, but the Men’s 9-10.5 size slid perfectly into my size 10 D Altama OTB boots without any trimming. They are thicker than the Ortholite Fusion Insoles, but firmer, which I think allows for better energy transfer. The higher volume translates to a fit that is much more similar to Altama’s stock rubber insoles, but with a material that makes more sense if you aren’t planning to take the boots under water. I’ve tried wearing one Sof Sole insole in one boot and one Altama rubber insole in the other, and the fit feels nearly identical. I recommend the Sof Sole insoles if you’re unhappy with the breathability or tackiness of the insole that came with the Altama OTBs, and I think they are worth consideration for other footwear in the lightweight hiking category. They are likely too thick for minimalist running shoes.

A Brief Survey in Marin

This past Sunday I rode to Mount Tam.

The electrical grid was down throughout Marin county, and for some reason that meant the state had closed some of the roads in the park to motorized traffic. Fortunately my vehicle runs on man-power and works just fine when the power is out. I figured the closure would make the ride more pleasant and I would just slip around any gates.

As I was riding in the general direction of fire I decided it would be prudent to throw a radio in my handlebar bag. From past experience I know that my cell phone reception can be spotty at the best of times in the hills and valleys up there. I assumed that the power outages and strong winds wouldn’t do me any favors. (It turns out I was right.)

After much climbing and much wind I reached Ground Equipment Facility J-33. This abandoned Nike missile site on the West Peak of Tamalpais is a reliable site for radioing. It has been host to a couple Field Days and was the destination of last year’s SOTA trip. And it’s a nice spot to bicycle to.

The Marin Amateur Radio Society maintains an excellent network of linked repeaters that I was able to hit immediately upon turning on my radio. Despite the distance, I was also able to reach back into San Francisco. Line of site to Sutro Tower meant I had a clear, strong signal on the San Francisco Radio Club repeater W6PW. I talked to a guy on there who told me that the Marin Radio Amateur Civil Emergency Service had been activated due to the fires. I keep some of the Marin RACES simplex frequencies programmed into my radio, just in case Godzilla walks through the bridge and we have to coordinate across the bay, so I jumped over to those channels to listen for any action. After that I was able to reach out to the East Bay, and listen to the effects of the fires that had just started that day in Contra Costa County.

After completing my survey of the airwaves I flew back down to sea level at approximately Mach 3, though I had to stop once for a California Highway Patrol helicopter that decided to use the gated off road as a landing pad.

It’s impressive what you can get done on a little handheld radio with 5 watts and a small antenna, assuming you can get to a good position. A bicycle is a good way to get there.

This time of year it is traditional for me to treat my saddle.

While the weather is still warm and pleasant here in Baghdad by the Bay, the hot sun and ass sweat of summer is fading into the past, and The Great Wet is on the horizon. Tonight I took my saddle to the sink and rinsed it off with some Dr. B. I don’t wash it every year, but it looked like it wanted it. After drying, I treat it to a sensual massage with a healthy helping of Obenauf’s LP. Obenauf’s products have served me and my leather well for a while now, and it’s a nice treat for my skin. The saddle will take a couple of coatings tonight. In the morning I’ll wipe off the top, and then give it an ass polishing with the day’s riding.
