I met with a client earlier this week who asked me to go over their vulnerability scans for a bit of a sanity check. He asked some important questions, but one in particular seems worth sharing. What can we do with Java? Can we solve the Java problem?
Cyber security podcasts I listen to
Yesterday, after reading a post in which I cautioned about a popular security podcast, someone asked me what cyber security podcasts I do listen to. I wrote this up a long time ago and never posted it for some reason, so now I’m correcting the oversight. Here’s my collection of the best of the best security podcasts.
These are the security podcasts I’ve been listening to for several years now and continue to recommend. Security podcasts are a good way to keep in touch with current issues, and also a good way to get continuing education.
Repair a Marx 709 transformer

Internally, a Marx 709 transformer differs little from a Marx 1209, so those instructions work for actual repair. But disassembly is a bit different, so I’ll walk through the disassembly process now.
Repair a Marx 1209 transformer

Want to repair a Marx 1209 transformer? There are two schools of thought. One is that small, sub-75 watt transformers from starter sets aren’t worth fixing because they are so cheap. The other is that since they are so cheap, you have nothing to lose by trying.
Marx didn’t design its transformers to be fixed, but the design is extremely simple. The hardest part really is getting the case apart and then getting it back together. If Marx had designed them to be serviced, like its competitors did, they would have cost more, so we wouldn’t have as many Marx trains to enjoy today. So it’s easy enough to forgive Marx for this.
Let’s dive in.
Sakai trains: The “Japanese Marx”

Sakai trains were made in HO and O gauge by a Tokyo-based manufacturer and sold abroad, particularly in the United States and Australia after World War II. Sakai’s O gauge product bore a curious resemblance to Marx. I have read speculation that Marx once used Sakai as a subcontractor, and Sakai used the tooling to make its own trains rather than returning it to Marx, but there are enough differences that I don’t think that’s the case.
What I do know is that Sakai’s O gauge product was a curious blend of cues from Lionel and Marx and the trains worked pretty well. They’re hard to find today, but not especially valuable since few people know what they are. They turn up on Ebay occasionally.
“Super utility” tinplate train cars
Tin train cars had a variety of methods to couple them together, but by far the most common method was a coupler commonly called tab-in-slot. The tab from one car mated with a slot in the next. All of the train manufacturers used a variant of this method at one point or another, and all of them would be able to couple together, if not for one nagging detail: height.
Repair a Marx reverse unit

When it comes to Marx repairs, the reverse unit is the end of the innocence. Motor repairs are rather easy; reverse unit repair can be as hard as you want it to be.
I’ll share some things I do that seem to make it easier to service a Marx reverse unit.
Fix a seized Lionel motor
I got a 4-wheel Lionel motor over the weekend. It was seized up to the point that the wheels wouldn’t turn, which meant I got it for almost nothing. The fix isn’t always this easy, but it’s common enough to be worth taking a chance on these neglected motors.
The low-effort fix for a Marx motor

I had a Marx motor that wouldn’t run, and I fixed it with almost no effort. If you need to get a Marx motor running again but can’t put a lot of time and effort into it, I’ve developed a quick fix. It’s only temporary, but if you want to run trains today instead of fixing them, it can get you out of a pinch.
You need a screwdriver and one drop of Rail-Zip.
How to install American Flyer track locks

To held tracks hold together without nailing them down permanently, AC Gilbert marketed its #694 track locks. Sometimes people also call these track clips. The locks are u-shaped pieces of tin that came in a brown envelope with instructions on the front. If you’ve lost the instructions, or bought the clips secondhand and never got them, here’s how to install American Flyer track locks.
These track locks are indispensable for setting up a layout on the floor.
