Shared Web Hosting

KnownHost
KnownHost
KnownHost Gets Top Marks in Shared Web hosting!

I got so fed up with my Web hosting provider (who will go nameless) that I decided to switch the hosting of my websites, and I'm glad I did!

After a careful, thorough search I settled on KnownHost, in part because it's fiercely independent, not part of a big conglomerate, and my experience has been stellar:

  • Migration was free, fast and efficient, even my tricky legacy apps.
  • Support has been outstanding, fast and responsive. 
  • Performance has been spectacular. My websites have never been so fast!
  • Ownership means they prioritize customers, not shareholders.  

Bottom Line: Premium hosting at a reasonable price point, ideal for those who value quality over the lowest cost. Highly recommended.

Lithium USB-C Rechargeable AA Batteries

Lithium USB-C Rechargeable AA Batteries
Lithium USB AA Batteries
At last, AA batteries that maintain constant 1.5 volts!

A big problem with alkaline AA batteries is that cell voltage decreases with discharge, so motors run slower and lights get less bright. Standard rechargeable NiCd and NiMH AA batteries suffer from lower cell voltage to begin with. But the latest lithium technology solves both problems:

  • Constant voltage: The best ones maintain a constant 1.5 volts until near depletion, when they step down to 1.1 volts to signal that it's time to recharge. Motors and lights thus deliver peak performance.
  • Convenience: The latest version recharges rapidly though a USB-C socket, which makes recharging super convenient.
  • Options: In addition to AA, lithium rechargeable batteries are also available in AAA, D and 9V form factors with the same great benefits. 

But beware marketing hype. Many of the less reputable batteries on the market make exaggerated, misleading claims. CARDIENS earns my Best Product rating by not making such claims.

Best Consumer VPN 2025-2026

Private Internet Access VPN
Private Internet Access VPN

Why you need a Virtual Private Network (VPN)

  • Encrypts your internet traffic, making it harder for others to read.
  • Hides your IP address and approximate location.
  • Helps protect your privacy from ISPs, advertisers, and other trackers.
  • Adds extra safety on public Wi‑Fi, where networks are easier to snoop.
  • Can help you access content or services that are region-locked while traveling.
  • Can help bypass censorship in places where websites or apps are blocked.

Why Private Internet Access (PIA) is my current favorite consumer VPN

  • Strong privacy: Independently audited no-logs policy and open-source apps.
  • Security features: Kill switch, strong encryption, split tunneling, and ad/tracker blocking. 
  • Large server network: 90+ countries.
  • Unlimited device connections: One subscription can cover all your devices.
  • Streaming and torrenting: Streaming-optimized servers and port-forwarding. 
  • Extra privacy tools: RAM-only servers and multi-hop options. 
  • Solid value: Affordable. 

Caveat 

  • Ownership: Kape Technologies conglomerate which is now private.

Electric Shaver Lubricant

Squalane Oil
Squalane Oil
Squalane Oil

To maintain your electric shaver in top condition it's important to regularly clean and lubricate it. The most common recommended lubricants are made from refined mineral oil, but they have two drawbacks:

  • Mineral oil can cause skin irritation.
  • They can be hard to clean up.

The secret lubrication alternative is squalane, a natural plant-derived oil that's good for your skin in addition to being good for your shaver, with high heat stability and viscosity. Plus it's inexpensive, available for only about $10 (e.g., at Target).

Android Alarm Routine Fix

Android Alarm Routine
Android Alarm Routine
Calendar Events and Task Announcements

As a result of Google messing with Android Tasks and Calendar Events, the presets for announcing them in an Alarm Routine may no longer work.

The work-around is to remove the presets and replace them with Try adding your own custom actions:

  • Tell me about today's calendar
  • Tell me about today's tasks

Note: The two Adjust Media Volume settings in my example are to first set the volume to 50 for a quiet room, and lastly to set the volume to 85 for normal daytime operation.

AI Threats to Privacy and Security

Duck.Ai by DuckDuckGo
Duck.ai by DuckDuckGo
Perplexity AI Now Requires Login

Should that concern you? Yes! Because your login facilitates harvesting and selling your personal information. It's called monetization, a sign of growing pressure on AI companies to stanch the flood of red ink.

Fortunately, there are a number of good AI alternatives that are less concerning from a privacy and security standpoint. Arguably the best of them is Duck.ai by DuckDuckGo. Private AI Chat. Free. Not only is it privacy-focused, like DuckDuckGo itself, but it also provides useful AI model choices. See Best Free AI Models You Can Run in a Browser Without Login.

If you want to use Perplexity as a guest to avoid the login, either:

  1. delete site cookies (to reset the guest allowance), or
  2. use it in a private/incognito browser window.

Google Pixel 9 Pro

Google Pixel 9 Pro
Google Pixel 9 Pro
Beauty that's only skin deep 

The Google Pixel 9 Pro is a study in contradictions. On the outside, it is one of the most refined, premium-feeling Android phones ever. On the inside, it is powered by a chip that would be more at home in a $500 mid-ranger than a $999 flagship, that's further handicapped by an out-of-date memory interface.

The heart of the Pixel 9 Pro is the Tensor G4. On paper, it is an 8-core processor built on Samsung’s 4nm node. In reality, it is a chip that barely outpaces its predecessor and gets crushed by the competition in raw power. It only has roughly half the multi-core power of a modern Snapdragon or Apple A-series chip.

Worse, to extend battery life, Google has resorted to aggressive power management, especially of background tasks. The result is a phone that lacks the responsiveness and smoothness of a high-end phone. It's particularly noticeable on speech-to-text, where phone struggles make it painful to the point of being unusable.

It also falls down on AI tasks. Google is pushing its Gemini AI to manage the phone, but it lacks the quick and predictable response of the old algorithmic Assistant (which is fortunately still available).

Is there a better phone? Not if you value the compact size. The better phones are bigger. 

Bottom Line: It's a decent phone if you get it on sale, tune it carefully, and don't push it too hard. 

Note: There is now a Pixel 10 Pro, but it's not much better than the Pixel 9 Pro.
