Even after reading this excellent article by the guy behind Halide, I’m still mystified by Apple’s ProRAW format. The question that keeps popping up in my mind is: if computational photography processing is involved in creating the ProRAW file (in DNG format), how can we still call this a variant of a RAW image?

Today, I finally saw the Dune movie, by the Canadian director, Denis Villeneuve. As a Canadian myself I’m so proud of him! It’s not a movie review, far from it. Let me just say that when I think about this movie, the word “equilibrium” comes to my mind. The movie is well balanced: storyline, intrigue, visual effects (visual effects serving the story), music, Dune’s world imaginary world. But the best for me were those “ornithopters”. Wow, they were sooooo cool! Can’t wait for the next part.

Have you seen the movie? What do you think of it?

From 1993 to 1994, I owned a PowerBook Duo 210 sporting a trackball, a low-profile keyboard and a grayscale screen. I didn’t like the trackball as the pointing device. The keyboard wasn’t that great either. But, it was small, highly portable. Coupled with the Duo Dock and an external monitor, it was a cool and novel setup. It’s been a long time ago. This article was written using a M1 MacBook Air, in a coffee shop.

Why is Carrot Weather so popular? I’m a weather enthusiast and I like trying new weather-related applications. I use many all year long, but Carrot Weather is not part of my application arsenal. They recently introduced updated weather maps, but to get a sense of them, I would need to subscribe for a year subscription. Most of the interesting features are available in the premium tier. I like the maps feature, but I wonder how better they will get compared to the ones that I’m already using in MyRadar. iOS 15 brought a significant update to the weather too, but I find the maps lacking radar resolution.

If there are users of Carrot Weather subscription, tell me more, tell my why it is so nice?

👨🏻‍💻 I think it’s important that you know a bit about who’s behind this continuous musing feed. So, here you go.

Dear visitor, welcome to my blog. My real name is JF Martin, but I prefer to be called Numeric Citizen in cyberspace. This is my pen name (learn why I’m using this name). I’ve been an IT (Information Technologies) professional since the early nineties. I’m 58, I’m probably getting old, I know. I have many hobbies, but writing is the one that’s taking up much of my spare time. I spend about twenty hours a week on writing and publishing (fully documented here). Why? Get the answer in “I read, I learn, I write, I Share”. As explained in this post, I write about my passions, which revolve around Apple, photography, privacy protection and climate change.

As you can see, I have more than enough interests to inspire me. So much so that they are the source of my monthly newsletter.

You can find more information about me here.

That’s about it! 😳😅

Going back in time on previously published content can be the source of a few smiles. My oldest post on my main blog is about Micro.blog. Here is an excerpt:

This morning I found out the existence of a blogging platform called Micro.blog. Something very special. Very lean. Very light. Without ads. Leaner than WordPress. Yet capable. Close to Twitter but with less clutter.

It’s funny. It’s not about introducing my blog or something like “hello” world.

Well, well, well, it seems that data portability among CMS is an issue. Who knew! I’m trying to find an easy way to move a few posts from my WordPress blog into my Ghost website. Exporting data from WordPress seems like an all-or-nothing situation. There are a few plugins available for this. The problem is that the content isn’t easily imported into Ghost. The latter does have a plugin, but it doesn’t support selecting posts. I don’t want to do this manually.

Any idea or suggestions?

Update 2022-02-16: There is a follow-up to my quest, read all the details here

According to this year’s Six Colors Report Card, relationships between Apple and its developers’ community is in terrible shape. The trend isn’t looking good either.

Marco Arment said, “Apple’s tightening grip on App Store fees, attempts to reach into other parts of businesses that they don’t deserve, and extremely entitled and galling statements on the matter continue to be distasteful and extremely damaging to their reputation. It seems like a huge strategic blunder to inflame developer relations, generate bad PR, invite more regulatory scrutiny, and risk governments imposing much worse changes for such a small percentage of their revenue.”

Is Apple still able to read the room temperature, or it is blind because of its financial successes? For once, I think Apple should copy Microsoft’s leadership.

As reported in my previous blog post, I had a chance to perform a “tech refresh” of my sister’s WiFi installation at her house. As a satisfied user of Ubiquiti product, the Dream Machine, I suggested to go with a lower end model, the Amplify HD. She has a big two levels home, with numerous rooms that poses a challenge for good wireless connectivity. It was a delightful experience, from the unpacking to final configuration. It’s a beautiful device with an informative display.

The setup was simple. Turning off the AirPort Express after taking note of the SSID, so I could reuse it with the same password. This prevents the reconfiguration of every device connecting to the WiFi with an already known SSID-password combination. After the initial power up sequence, the router will ask the user to download the configuration application from the App Store. An account has to be created with Ubiquity. Thankfully, Sign In with Apple is available.

The next phase happens on the iPhone with an initial discovery over Bluetooth. The setup process is quick and flawless. As expected, a firmware update was waiting to be applied. During the update process, it was the right rime to deploy the two WiFi extenders, in strategic places where the WiFi signals used to be weak. Once completed, I could name each devices with a more meaningful name, to represent where were each device. All in all, the process took less than 30 minutes. It’s a very Apple-like experience. The following table shows the situation before and after the new router. Numbers speaks for themselves.

Mission accomplished. Another happy customer. I came back with the old AirPort Extreme. No idea what to do with it.

In mid-2020, I wrote about my experience of replacing an aging Apple AirPort Extreme with an Ubiquiti’s Dream Machine. Today, I’m kind of repeating the experience, but this time with the Amplify HD router, also from Ubiquiti, for my sister. Don’t expect a complete review, but expect a post with a few observations. My sister is having weak WiFi issues in her house and I suggested her to get the kit to form a mesh network. I’ll be taking measure before and after to see if it brings meaningful improvements in her big house. Stay tuned.
