Ciena figures out ways to increase throughput of fiber channels. The Verge Decoder podcast interviewed the CEO Gary Smith. It is one of those companies that you have never heard of but has been plugging away for 20 years. It’s a public company and all your data is squeezed down fiber lines using their technology.

Encouraging Effective Future Behavior through Feedback
I have been listening to the podcast “Manager Tools” for over 10 years and practicing their recommendations in my own company and projects.
Mark and Mike got together after their retirement for this cast and went into detail regarding the “The Purpose of Feedback” in a 3 part podcast series.
I summarized the three podcasts to make sure these gems are committed to memory.
The purpose of feedback is to:
Encourage effective future behavior
Organizations can’t really “encourage” so the task of encouragement falls onto a manager.
It doesn’t matter if the feedback is negative or positive. There is only one feedback model. (see below)
The tone of all feedback is positive to “encourage”.
Encouragement creates stronger relationships, Stronger relationships improve trust. Trust improves results and retention. Results and retention are the two key deliverables of every manager in the world.
Effective feedback doesn’t focus on the mistakes. Trying to do a root cause analysis will result in feedback that is too long. The purpose of feedback is not to talk about the mistake.
The shorter the model is, the better. 10-minute feedback session will result in you not providing feedback, but 10 seconds of feedback will be more effective. Feedback should be about small things, don’t try to accumulate a pattern of behavior.
Simply ask for something different in the future. Make it about the organization and not the individual. Describes a gap between what they did and what the goals and objectives are.
Feedback is a verbal measure of a directs contribution or lack of contribution to the mission and goals of the organization. (Some directs might feel judged, and you may need to say that you are not judging.) Managers and professionals don’t judge. They plan and measure.)
This is where you are, relative to what the organization needs from you.
Managers jobs are not to look for mistakes, but to encourage staff to be effective. Fear-based tactics don’t work and don’t help with retention.
Steps to give feedback
- Hey, can I give you some feedback?
- When you did that thing you did. (behavior)
- The outcome that happened
- Thank you, well done/Can you work on that? Can you do that differently?
The purpose of feedback is either, change their behavior in the future or do more of the same in the future. Don’t punish people or spend a lot of time talking about the past because that erodes trust. There is nothing you can do about the past.
Behavior is the engine of all systemic organizational success: not systems, processes, code, margins profit.
It is all about behavior. Behaviors have to be aligned to goals.
Motivations, intents, and attitudes. Intent is not what is important for the organization, so focus on behaviors. Motivation trap: All motivation is self motivation.
Behaviors can’t be faked. No need to guess or interpret.
Aggregated effective behavior leads to results.
Give feedback only about behaviors. Behaviors that you can give feedback on are:
- The words you say
- How you say them
- Your facial expressions
- Your body language
- Work product: Quantity, Quality, Accuracy, Timeliness, Documentation, Safety
When receiving negative feedback, directs will want to switch the conversation to what they meant. Tell them you know they meant well. Intent is not what is important for the organization.
All work behaviors are available to everyone all of the time (meritocracy). The manager needs to know what behaviors to ask for that align with the organization’s goals.
Use this model to stop the manager’s judgment and arrogant teaching.
Effective management is all about behaviors.
Summary: Encourage effective future behavior.

New Open Sourced VPN: Obscura
When new Rust applications come out I pay attention because the language attempts to make code more secure. Obscurais a new VPN open sourced on GitHub. It claims to not be able to log my activity and it is supposed to disguise traffic from network filters. It is actually reusing Mullvad VPN exit nodes. As I’m going behind the great firewall I’ve bought a month to test it.
Tip of had to Larry Salibra for bringing Obscura on my radar.
Genmo a good site to make some short AI Videos
Checking out Genmo to create AI-Generated Videos. Gotta take the temperature of this ever-evolving part of AI.
If we could just combine Singapore and Hong Kong we would have a perfect city:
When I asked for a Scottish Terrier, I didn’t expect such a cute puppy with the floppy ears. Seemed to do a good job with the mechanics and even threw in some tulips. I figured an all-black dog would be challenging, and it blew out the highlights when trying to simulate the sun shining off the fur.
Will check back in a couple of months.
New Launcher App Pieoneer forces my hands off the keyboard
I preordered the new Mac App called Pieoneer when I saw the cool design of the app.

My first stumbling block was when I forgot what the last symbol on the right in this graphic means:

After searching, it is of course the “Tab” key, but normally an App would let you know that. Strangely, if you click on the button and customize the keypress it writes “Tab” instead of the symbol.
What stopped me from using the program after I figured out how to call the Pie on my screen was that to select an option, I had to move my hand to my trackpad and then click.
For me, a launcher keeps your hands on the keyboard, and so I’m going to stick with the built-in spotlight. It was a promising design.
Parcel Shipments stopped from China and Hong Kong
During my decade in Shenzhen, Drop-shipping became a big business. The first startup I joined was based on it before it had that name. Some of it was based off a postal loophole that just got closed. AliExpress shipments are going to drop.

Using Mullvad VPN on Apple TV
I wanted to watch the “LA FireAid Concert” from Singapore, however, seems the concert was restricted internationally. I use the Mullvad VPN and realized they didn’t have an Apple TV version of their app.
Fortunately, I also had been playing with a private network app called Tailscale.
My first attempt was to use my Mac as an exit node of Tailscale while connected to the Mullvad VPN. This routed my Apple TV traffic through my Mac and then through Mullvad. Once I realized I had to approve the exit node in the Tailscale interface, it was a success!
For the first five minutes it was great, and then it started buffering and stopping. I was so close and tried to find out why Mullvad didn’t have an Apple TV app. According to their website, it is on the roadmap, but meanwhile, Tailscale actually has a Mullvad integration. For an extra $5 bucks a month, you can use Mullvad as an exit node. So you can set up the Tailscale app on Apple TV to connect to Mullvad. Once I paid for this add-on, I was able to get my Apple TV to direct its traffic to Mullvad and the buffering and skipping stopped.
