How to Manually Update TP-Link Deco Firmware

It’s less a how-to, but a PSA for Deco mesh routers users — the online automatic updates for firmwares on smartphone apps or web management are not working. In my case, automatic update said the version 1.2.13 is the latest, but the support page from TP-Link website clearly states v.1.2.14 is the latest with the patch I am looking for.

How to Run Interval Comparison in Shortcuts

It’s the allergy season of the year. My favorite weather apps are yet to cover South Korea’s allergy-related forecast, so I end up pulling present data from local sources. That being said, the number I get is not put into the useful context; I want to know if it’s low, moderate, or high, not the actual pollen count.

How to Stop External Monitors Waking Up Alone on macOS

If you happen to be using an external monitor with your Mac, either laptop or desktop, you may have noticed it has tendency to display blank dark display for brief moments only to go back into sleep, or standby mode, again. It’s less an issue as the Mac itself is not fully waking up, but it is nonetheless a problem as the monitor will keep trying to display ‘something’.

How to Transfer to eSIM: Lessons From SKT SIM Breach

Though the title may sounds like a proper how-to, I ended up deciding to write it as “documentation” of what happened in my particular case. It obviously won’t work for everyone, and your mileage will vary greatly. I believe the common core issues for everyone would be that nearby carrier stores would not have enough physical SIM cards to serve all the affected customers, roughly 23 millions, so we are being waitlisted. Unless you absolutely do need a physical SIM card, you can apply for transfer to eSIM. This post covers staying in the same contract, but changing the carrier…

How to Change Language on PS5 for Titles with Multi-Language Support

It’s one mouthful how-to post title, but the premise is simple for those of us who need this feature. There are PS5 titles that are sold under multi-language support, but the game itself simply lacks the language settings. For example, recently I found out Unicorn Overlord is sold with Chinese and Korean support in PlayStation Korea; the only problem is, my console being set in English, the game defaults into Chinese instead of Korean or English.

How to Record Blood Pressure for HealthKit with Shortcuts

While there are good blood pressure monitors with IoT features attached, not all products support Apple HealthKit, let alone have accuracy required to be useful. As some reviews would have put it, smart BPM may not have ‘bang for the buck’, and the convenience offered by the device may not worth the bother if the measurements weren’t accurate in the first place.

How to Fix Roborock Room Names on Home App

Roborock began to roll out Matter support on its latest models, and with it, HomeKit can now finally see a Roborock branded robot vacuums. So far, my experience with vacuum supports on Matter platform was it cannot completely replace the manufacturer’s official app; however, it is useful enough to automate “stop” or “pause” where it would be easier to take advantage of other IoT sensors.

How to Change Mail App Badge Counts to All Unread

With the introduction of Mail app categorizations in the iOS 18, Apple is now walking the same path other email services have been on for decades and equally created a gimmick — auto email categorizations. With or without AI, I’ve never seen email categorizations work properly in any context, let alone professional one. Had any tech giants have the technology to create an email butler, we would have seen it first changing the tide of losing fight that is the spam emails.

How to Troubleshoot Steam Synchronization Issues

This isn’t the solution that will fix all synchronizations on Steam platform. Instead, I decided to keep it as a documentation purpose, as most of the posts and articles I could find on the subject hardly touched on it. If you are seeing “Unable to sync” on the Steam client for all games, you are on the same boat as I was.

How to Scan Documents into PDF on Notes App

I understand there are good scanning apps available on the App Store, but their life-time licenses are not competitively priced to that of specialized scanners for going paperless. One such brand known for book scanners and included scanning suite is Czur, and its scanner starts as low as $99 on Amazon; whereas, some of the popular scanning apps I could had monthly or annual subscriptions attached to it. If you scan documents on a regular basis, I would recommend investing on a good scanner and the suite.

How to Batch Incrementally Edit Times on Photos

One of the nonsense I had to pull myself through during scanning old family albums was its lack of metadata. I could guess the date of when the photo might have been taken, but photo library apps of any kind would rely on time stamps as well to order the photos. In order to correctly display which photo was taken first from the roll, the program relies on time stamps; and it is that very time stamps scanned photos do not have.

How To Band-Aid Fix mDNS not Resolving Over VPN

I’m calling it a band-aid fix, because this is technically not a “fix”. As far as I could find, it is technically not possible to use mDNS (Bonjour) over VPN. Only when the remote client is bridged through VPN mDNS packets can reach the client, but it causes its own havoc, especially less useful for home and small office environment as not all devices would support bridge mode. Apparently the problem itself, trying to reroute mDNS packets over VPN, is rather an obscure goal, and routers and its firmwares simply do not support such functionalities.

How to Iterate Through Dictionary on iOS Shortcuts

I’ve talked about using dictionary in Shortcuts to handle data. If you started using one in a custom shortcut, there is one odd bit that may not be immediately obvious if you try to loop through the dictionary; it loops with the entire dictionary as the Repeat Item. It defeats the purpose of using iterating through dictionary if it cannot parse the dictionary for iteration.

How to Fix iCloud Photos “Unable to Join Shared Library”

I recently started digitizing family albums; it was more or less a moral lesson on the importance of metadata. The lab did pull through. The stack of negative films my family had couldn’t be “scanned” in traditional sense, so we had them digitized in a photo lab. The results from the lab were underwhelming yet expected — many films had aged. But it wasn’t anything but the Apple’s Photos app that troubled me the most. It wouldn’t let another family member to join the shared library.

How to Upgrade WiFi Router Platform-Agnostically

Upgrading a router every few years takes more than what it should. The price tag on these machines is generally on par with entry-level smartphones, and smartphones with the average upgrade cycle of 4 years have better upgradability and migration softwares. Not to mention, all the manufacturers are eager to support migration away from the competitors. Routers, from my experience, don’t do that.
