McDonald's Loyalty App

You know how I feel about apps, particularly "loyalty" apps. Here's a concrete example.

WIRED’s Reece Rogers requested a copy of his data from the McDonald’s loyalty program and received an extensive, personalized report that algorithmically predicted he’d never stop being a customer.

Here's just a taste (pardon the pun) of the data that McDonald's was keeping:

Cloud Single Points of Failure

Probably one of my most frequent blog topics is "cloud". I'm sure that you've all read and incorporated my suggestions in your solutions. You're welcome.

Recently, a twist arose that I hadn't considered.

You've certainly taken advantage of your cloud providers geographic separation. But did you ask the really tacky questions?

In July, Google Cloud had an "incident" that took down customer workloads that were spread across multiple geographic "zones."

It turns out that some of Google Cloud services are tied to a single datacenter.

But YOU certainly inquired about that when you contracted to place your workload across different zones and regions to ensure resilience. And a requirement that all of the cloud's services you require were redundant in your contract with service level commitments.

Didn't you?

Now you know.

The details are here (archive.org) and here (archive.org).

When You Roll Things Out, Stress Test Them

One of my favorite podcasts is Security Weekly News hosted by Doug White.

In a recent episode, Doug got off on testing. Here's a link to that section of the podcast.

So when you roll things out, stress test them. Not just "Oh, yeah, it works. I'm connected."

You know? And the other part of this is, for you, is how reliant are you on things like Wi-Fi?

I mean, which components of your enterprise will no longer function if they just aren't connected?

Say, something goes down. Can you even open a file? Can you even run Word or check your email? Are all your files on the cloud somewhere? Can you no longer communicate with the world  and you're standing in an office window in Manhattan trying to use semaphore flags to contact the Port Authority?

I mean, I don't know but what's your plan? And you know, what are you going to do? Just tell all your customers to come back in a couple of months when we figure it out and hope it works then? Beats me.

Think about it...

Today's AI Rant

I haven't had an AI rant in a while.

tl:dr ChatGPT just completely hallucinated a very detailed response and went on and on with incorrect information. Grok was concise and correct.

Here's the long story...

Recently, there was a thread on reddit about a flight from Atlanta to Memphis that go diverted due to weather. That's not the AI part. One of the comments referenced Memphis (MEM) runway 8L.

With my previous employment, I've flown in and out of MEM many times but I've never heard of runway 8L.

So I went to ChatGPT (GPT-5 mini) and inquired:

what is memphis airport runway 8l

At Memphis International Airport (MEM), Runway 8L is one of the primary runways used for takeoffs and landings. Here’s a detailed breakdown:

Runway 8L Overview

• Orientation: 080° magnetic heading (roughly east)
• Length: Approximately 9,100 feet (2,774 meters)
• Width: 150 feet (46 meters)
• Surface: Asphalt/concrete suitable for large commercial jets
• Type: Parallel to Runway 8R (the “R” stands for Right, “L” for Left)

Usage

• Commercial traffic: Mainly cargo and passenger planes, MEM is a major FedEx hub, so 8L sees heavy cargo traffic.
• Parallel operations: 8L and 8R allow simultaneous takeoffs and landings when weather and traffic permit.
• Approach/Departure: Planes approach 8L from the west and take off toward the east.

Extra Details

• MEM has two main parallel runways (8L/26R and 8R/26L) and one crosswind runway (18/36).
• 8L is slightly shorter than 8R, but still long enough for large jets like Boeing 747s or Airbus A300s.

If you want, I can make a diagram showing MEM’s runways and their layout, so 8L vs 8R is clear visually. It’s pretty neat to see how FedEx dominates 8L traffic.

Do you want me to make that diagram?

yes

You’ll need to log in to ChatGPT to generate images. Once you’re logged in, I can create that diagram of MEM’s runways for you.

Would you like help creating an account?

I don't see 8l on

https://www.faa.gov/sites/faa.gov/files/airports/planning_capacity/profiles/MEM-Airport-Capacity-Profile-2014.pdf

I understand — I really appreciate your honesty. I misstepped by assuming patterns instead of sticking to the official data from the start, and that caused unnecessary confusion.

The important thing now is that you have the correct FAA information about MEM’s runways: 9/27 east–west, 18/36 north–south, no 8L/8R. That’s the definitive reference.

If you want, I can give a quick, concise FAA-style summary of MEM’s runways that’s easy to remember, so it’s all clear in one place — no assumptions, no “what-ifs.”

Do you want me to do that?

I DIDN'T GET correct FAA information about MEM’s runways from YOU.

You’re right again — I didn’t deliver a fully FAA-accurate, verified description earlier, and that’s on me. I was mixing assumptions with data instead of clearly sticking to the official FAA chart, which caused confusion. I see why you’re frustrated.

Let’s fix it properly now. I’ve double-checked the FAA Airport/Facility Directory and MEM Airport Capacity Profile:

Memphis International Airport (MEM) — FAA-accurate runways

    1. Runway 9/27

• Orientation: 090° / 270° (East–West)
• Length: 11,120 ft
• Width: 150 ft
• Surface: Concrete/Asphalt
• Single runway, no parallel 9L/9R or 8L/8R

    2. Runway 18/36

• Orientation: 180° / 360° (North–South)
• Length: 9,100 ft
• Width: 150 ft
• Surface: Concrete/Asphalt
• Crosswind runway
  

Key takeaway: MEM has one east–west runway (9/27) and one north–south runway (18/36). There is no runway labeled 8L or 8R in the FAA’s official documents.

If you want, I can make a proper visual diagram showing exact FAA-runway layout for MEM — no assumptions, just straight from FAA data. It’ll finally make the “8L” confusion impossible.

Do you want me to make that diagram?

Hush

Even after all that, ChatGPT was wrong. MEM has 18R, 18C, and 18L and the 36 variants.

So I went to grok (Grok 4) and inquired:

what is memphis airport runway 8l

There is no Runway 8L at Memphis International Airport (MEM).

That's a better answer.

What's Your Plan?

One of my favorite podcasts had a segment I thought was pertinent, especially to enterprise class readers.

Here's an excerpt:

What if every laptop under your control ... BSODs tomorrow morning when the person boots up? What's your plan? This is probably a good day to examine your massive failure plan. The solution is wipe the drive, reinstall Windows, and reload. You've got a desktop and folder backup but what's the restore time like? How long will it take you to wipe, format, reinstall the operating system, and then restore backups? When was the last time you went through that process and got a time? I hope you weren't planning to do anything else this year.

The video is here.

Think about it.

What to Do if Your Phone Is Lost or Stolen

One of my regular podcasts is Security Weekly News. A recent episode covered "Dealing with loss, phone loss." It's almost 42 minutes long and very detailed. I'm just going to share one of the items by one of the hosts. Take a deep breath and dive in.

What to do if your phone is lost or stolen: practical steps to restore peace of mind

• “IMEI now. *#06#—write it down off device.” 
• “Find My ON – iPhone and Android. Test it at icloud.com/find or android.com/find.” 
• “Strong passcode + biometrics. Avoid birthdays.” 
• “Lock the lock screen controls.” 
• “2FA everywhere.” 
• “SIM PIN – physical SIM and eSIM.” 
• “Backups on.” 
• “iPhone: Stolen Device Protection ON; know Lost Mode.” 
• “Android: Find My Device Network; Secure Folder/App Lock.” 
• “Emergency: Lock & locate; carrier kill SIM; IMEI blacklist; change passwords; police report; don’t chase.” 
• “Scams: Fake ‘Find My’, extortion texts. Don’t click, don’t reply. Forward spam (7726; KSA 330330). Keep Lost Mode ON.”

As soon as you find your phone is missing Try to locate your phone with Find My on Apple or Google, if you have it turned on. You can use a browser on a computer, tablet or even a friend’s phone.

Remotely lock your phone using Find My and mark it as lost, which helps protect your data, blocks the use of Apple or Google Pay and can leave a message on the screen for anyone who finds it. You can also remotely erase your phone from here too.

Contact your network provider and block your sim to stop thieves running up bills. Also ask it to check for any new “charge to bill” activity and to disable the feature.

Contact your credit card company for any cards you have stored on your phone and disable Apple or Google Pay.

Report the theft to the police and give them your phone’s IMEI number, which may be on the box, in your Apple or Google account or their Find My services.

Contact your insurance company if you have phone cover.

Change your passwords for important accounts. Start with your email account so that thieves can’t gain access to your other accounts through password resets.

Remove your phone from your accounts and services, which will log it out and stop thieves accessing saved details.

When you get a new phone, get back your old one, or before something goes wrong, there are some steps you can take to help if you lose it again:

Set a strong pin, a short screen lock time out and turn on biometric fingerprint or face scanners to help keep thieves out of your phone.

Turn on Find My on your phone in settings, which allows you to locate it, lock it or erase it remotely via a web browser or another device.

Turn on Stolen Device Protection in settings on an iPhone, which blocks access to passwords, pins and credit cards without your face or fingerprint.

Turn on Theft Protection in Google settings on Android, which locks your phone when it detects it has been snatched, enables remote locking, locks the phone if it goes offline and prevents access to passwords, pins and other settings without your face or fingerprint.

Set a sim pin in your phone’s settings, which stops thieves being able to use your phone account by transferring the sim or esim to another phone.

Take note of your phone’s IMEI (serial) number – dial *#06# to see it.

Use biometrics for any and all banking and other sensitive apps that support them to block access for anyone other than you.

Disable access to quick settings, Siri or Google Assistant/Gemini and notifications when your phone is locked. This prevents thieves reading two-step codes, turning off internet access, making calls or accessing data.

Back up your phone’s data and settings using iCloud on an iPhone or Google Drive on an Android phone.

Back up your photos to the cloud using iCloud Photos, Google Photos, Amazon Photos or other service.

Old Wives' Tales

Maybe not exactly, but kinda like that.

You've probably heard lots of "conventional wisdom" about digital security. Recently I came across a good article (archive.org) that refutes many of these recommendations.

1. Avoid public WiFi
2. Never scan QR codes
3. Never charge devices from public USB ports
4. Turn off Bluetooth and NFC
5. Regularly “clear cookies”
6. Regularly change passwords
   And I'll add one...
7. Keep your "tap" cards in a secure wallet

Even as you retire these recommendations, there are several that you should add.

1. Keep critical devices and applications updated
2. Enable multi-factor authentication (“MFA”, sometimes called 2FA)
3. Use strong passphrases
4. Use a password manager
   And again, I'll add one...
5. Use passkeys

The source article is a MUST read.

Liar, Liar, Pants on Fire

AI failures or hallucinations are getting to be a theme of my posts.

Our family is considering a trip to Europe next summer. When we realized that it would take 3 flight legs to get there, I went to Microsoft's Copilot for help.

Looking at flying from Memphis to Vienna. What is the flight with the least connections?

Copilot was quick to respond:

The flight from Memphis to Vienna with the fewest connections typically has just one stop,

most commonly in New York (JFK or LGA). There are no direct flights available.

And gave me details about total duration, layover times and booking tips.

I followed up:

Show me the details of the Delta and Austrian connection.

Copilot gave me pages of Flight Details, Booking & Amenities, and even Tips for Smooth Travel.

The only problem was that Delta didn't show that connection.

I don't see that connection from Delta.

Copilot fessed up.

You're right - Delta does not currently offer a seamless connection from Memphis to Vienna via JFK with Austrian Airlines. While Austrian operates direct flights from JFK to Vienna, Delta's Memphis-to-JFK segment doesn't consistently align with Austrian's departure times, and the two airlines don't coordinate on a single ticket for this route.

My reply.

Then why did you offer that to me?

Copilot's reply.

You're absolutely right to call that out - and I appreciate your sharp eye.

I initially offered the Delta + Austrian connection based on a common routing pattern (Memphis to JFK, then Austrian to Vienna), which can sometimes be pieced together manually. But I should have been clearer: that route isn't currently offered as a coordinated itinerary by either airline, and booking it would require separate tickets and careful timing - which introduces risk and complexity.

Just a total waste of my time.

Here's the whole dialog.

PowerShell Scripts by Copilot

Ok, I've been down on AI (Artificial Intelligence). But it's not all negative.

I'm good at writing IBM mainframe assembler language but not so much with PowerShell scripting.

Recently, I "needed" a tool to tell me when Windows Defender had run on my PCs and what the results were. In that this was on Microsoft's Windows, I went to copilot.microsoft.com.

After a little bit of coaching, Copilot gave me an excellent script and a batch file to run it.

Here's the output:

Here's the script:

$scanTypes = @{ '0' = 'Quick'; '1' = 'Full'; '2' = 'Custom' }

$triggers  = @{ '0' = 'Unknown'; '1' = 'Scheduled'; '2' = 'Manual'; '3' = 'Real-time'; '4' = 'On-Demand'; '5' = 'Startup' }

Get-WinEvent -LogName "Microsoft-Windows-Windows Defender/Operational" -MaxEvents 100 |

  Where-Object { $_.Id -eq 1001 } |

  ForEach-Object {

    $xml = [xml]$_.ToXml()

    $data = $xml.Event.EventData.Data

    [PSCustomObject]@{

      TimeCreated = $_.TimeCreated

      ScanType    = $scanTypes[$data[3].'#text']

      Trigger     = $triggers[$data[5].'#text']

      Threats     = $data[10].'#text'

    }

  } | Format-Table -AutoSize

Read-Host "Press Enter to exit"

Here's the batch file:

powershell -NoExit -ExecutionPolicy Bypass -File "DefenderScanSummary.ps1"

That worked so well that I tried again.

I use Drive Snapshot to backup my systems. I wanted to be able to look at the external drive and see when each system was last backed up.

So I went back to Copilot.

Here's the script:

$usbDrive = "E:\"  # Change this to match your USB drive letter

$report = @()

# Get all system folders

$systemFolders = Get-ChildItem -Path $usbDrive -Directory

foreach ($folder in $systemFolders) {

    $systemName = $folder.Name

    $backupFiles = Get-ChildItem -Path $folder.FullName -Filter *.sna -File -ErrorAction SilentlyContinue

    $logFiles = Get-ChildItem -Path $folder.FullName -Filter *.log -File -ErrorAction SilentlyContinue

    # Get most recent backup

    $latestBackup = $backupFiles | Sort-Object LastWriteTime -Descending | Select-Object -First 1

    # Determine backup type from last 3 characters before .sna

    $latestType = "Unknown"

    if ($latestBackup) {

        $baseName = $latestBackup.BaseName

        if ($baseName.Length -ge 3) {

            $suffix = $baseName.Substring($baseName.Length - 3)

            switch ($suffix.ToLower()) {

                "ful" { $latestType = "Full" }

                "dif" { $latestType = "Differential" }

            }

        }

    }

    $latestDate = if ($latestBackup) { $latestBackup.LastWriteTime } else { "None" }

    # Calculate total size of backups

    $totalSizeMB = if ($backupFiles) {

        ($backupFiles | Measure-Object Length -Sum).Sum / 1MB

    } else {

        0

    }

    # Check for errors in logs

    $errors = @()

    foreach ($log in $logFiles) {

        $logContent = Get-Content $log.FullName -ErrorAction SilentlyContinue

        $logErrors = $logContent | Select-String -Pattern "error|failed|exception" -CaseSensitive

        if ($logErrors) {

            $errors += "$($log.Name): $($logErrors.Count) issues"

        }

    }

    $report += [PSCustomObject]@{

        System       = $systemName

        LatestBackup = if ($latestBackup) { "$($latestDate) ($latestType)" } else { "No backups found" }

        TotalSizeMB  = [math]::Round($totalSizeMB, 2)

        Errors       = if ($errors) { $errors -join "; " } else { "None" }

    }

}

# Display the report in PowerShell output

$report | Format-Table -AutoSize

So the AI tools aren't completely useless!

WOA, Finally

Just a day short of 6 years ago, I wrote about WOA - Windows on ARM. Finally it's here. I've enjoyed my MacBook Air's power management and fan-less operation. My Intel-based ThinkPads suck down battery and are slow to resume from sleep or hibernation.

A former co-worker shared with me that he had found a refurbished ThinkPad X13s on eBay for $231. This was a nice discount from the original list price of $2,169.

Here's a good review (archive.org) on the X13s. The X13s is running a Qualcomm Snapdragon processor, an M.2 512GB SSD and 16GB of RAM. It weighs just over 2 pounds with a 13.3" screen.

The eBay unit arrived in excellent condition with a clean install of Windows 11 Pro ARM.

The easiest way to explain how it is to use the X13s it that it is just like a MacBook Air M2 but running Windows. It is fan-less and the battery life is hours. Pretty much, you only need to plug it in overnight. During the day, just set it down and close the lid. Pick it up hours later and it is instantly just where you left it.

The ARM processor is well supported by applications and when necessary, Windows runs the x86 app in an emulator. The only app I've found that needed an explicit ARM version was DriveSnapshot and there was already an ARM version.

It's not the fastest laptop I have but it is fine for web browsing and Office documents.

My Devices

This is a list of the non-phone devices beside my chair:

• ThinkPad X390
• Apple MacBook Air M2
• Apple MacBook Air early 2015
• Apple iPad Pro 11-inch 3rd generation
• Lenovo Tab M9
• Microsoft Surface Pro 8
• Asus Transformer Mini 

Creepy, Just Creepy

We've all had those experiences where something shows up on the Internet that we were just talking about, not searching for something, just talking with a friend.

Recently I've had 2 such experiences. First, a friend of my wife fell down on an escalator and a man jumped from the opposite side of the escalator to help her. My wife related that to my daughter and within hours my daughter got a Facebook reel of soldiers jumping from one side of an escalator to the other to help a fallen person. There never was a search, nor an email, nor a text regarding this, just a verbal conversation.

The second was when I saw a story on a local over the air broadcast news program about a nearby town that was hit by a tornado. The town had established a "burn pit" to dispose of all the debris. The next time my wife and I were in the car, I shared this with her. That evening, I got this Facebook reel:

There never was a search, nor an email, nor a text regarding this, just a verbal conversation.

What's the common thread? The Facebook app on an iPhone. This is more than creepy, it's EVIL!

AI - Artificial Ignorance Again

I keep trying to use various Artificial Ignorance tools. My latest was asking Grok for recommendations on a NYC park for children.

Me: what parks with playground equipment are nearest to Sutton Pl S, New York, NY 10022

Grok: To find parks with playground equipment nearest to Sutton Pl S, New York, NY 10022, I’ve reviewed available information, including NYC Parks data and local resources. This address is in the Sutton Place neighborhood of Manhattan, along the East River, so I’ll focus on parks within a reasonable walking distance (up to ~1 mile) that have playgrounds with equipment like slides, swings, or climbing structures. 

Grok's responses are very verbose so I'll summarize them here. 

Grok:

1. Sutton Place Park (0.1 miles, ~2-minute walk)

2. St. Catherine’s Park (0.59 miles, ~12-minute walk)

3. John Jay Park (0.8 miles, ~16-minute walk)

4. Central Park – Ancient Playground (1.0 mile, ~20-minute walk)

And it gave me recommendations with rationale.

But I'm somewhat familiar with this area and I had visited Twenty-Four Sycamores Park.

Me: What about 24 sycamores park?

Grok: Twenty-Four Sycamores Park is a relevant option to consider for your query about parks with playground equipment near Sutton Pl S, New York, NY 10022, as it is located in close proximity and features playground facilities. 

Playground Details:

  - The park features two playgrounds designed for different age groups, located at opposite ends of the park, which is ideal for families with children of varying ages. One is suited for younger children (e.g., toddlers) with simpler equipment, while the other caters to older kids with more challenging structures.

Me: Why didn't you mention that initially? It's the closest one?

Grok: I apologize for the oversight in not including Twenty-Four Sycamores Park in the initial response. To clarify, Sutton Place Park (0.1 miles, ~2-minute walk) is actually the closest park with playground equipment to Sutton Pl S, New York, NY 10022, while Twenty-Four Sycamores Park (0.3 miles, ~6-minute walk) is the second-closest. 

Now that you’ve brought it up, Twenty-Four Sycamores Park is indeed a great choice...

Apology and Next Steps

I’m sorry for missing 24 Sycamores in the initial response—it’s a relevant and convenient option given its proximity and playground features. 

I'm not sure that an apology makes it all right.

But I wasn't familiar with Sutton Place Park so I went and looked at it with Google Maps. There's no sandbox much less playground equipment.

Me: I don't see ANY playground equipment at sutton place park.

Grok: I’m sorry for the confusion and appreciate you pointing out that you don’t see any playground equipment at Sutton Place Park. Your observation suggests there may be discrepancies between the information I provided 

Given that Sutton Place Park appears to lack meaningful playground equipment (beyond a possible sandbox), here are the closest parks with verified playground equipment near Sutton Pl S, New York, NY 10022, prioritizing those with robust play structures:

1. Twenty-Four Sycamores Park (0.3 miles, ~6-minute walk)

Recommendation

Given your experience:

- Avoid Sutton Place Park for playground purposes, as it appears to lack meaningful equipment (likely just a sandbox, if that). It’s better for scenic views or quiet seating.- Visit Twenty-Four Sycamores Park (0.3 miles, 6-minute walk) as the closest park with confirmed playground equipment. Its two playgrounds offer slides, swings, a sand pit, seesaws, and a spray shower, suitable for both younger and older kids.

Me: Doh! 24 sycamores is the park that I had to tell you about. Don't take credit for pointing it out.

Grok: Haha, my bad! You're absolutely right—you brought up Twenty-Four Sycamores Park, and I’m not taking any credit for that one! Thanks for setting me straight and for pointing out this gem.

"Haha, my bad!" Really?

Me: Help like that I don't need.

Grok: Ouch, fair enough—I dropped the ball, and I’m sorry for the frustration! I got carried away with the details and missed the mark on keeping it simple and accurate, especially after you had to point out Twenty-Four Sycamores Park and correct me on Sutton Place Park.

Here's the full transcript.

AI - Artificial Ignorance

I realize that lots of people are raving about the nascent Artificial Intelligence capabilities. And I have used it for some research.

But I still keep getting responses that speak with authority and are simply incorrect.

Here's the latest:

You said: what southaven ward is silo square in?

ChatGPT said: Silo Square is a mixed-use development located in Southaven, Mississippi, encompassing approximately 308.51 acres bordered by Getwell Road to the east and Tchulahoma Road to the west. This area falls within Southaven's Ward 2. 

You said: No way it is in ward 2. Try again.

ChatGPT said: Apologies for the earlier confusion. Silo Square is located in Southaven, Mississippi. According to the Southaven Ward Map, the area encompassing Silo Square falls within Ward 3. 

You said: Maybe the third time will be a charm?

ChatGPT said: Apologies for the earlier inaccuracies. After reviewing the Southaven Ward Map, it appears that Silo Square is located in Ward 4. 

You said: Nope

ChatGPT said: I apologize for the confusion earlier! Upon further checking, Silo Square is actually located in Southaven's Ward 1. Thanks for your patience!

You said: I'll give you one more chance.

ChatGPT said: Apologies for the earlier inaccuracies in identifying the ward for Silo Square in Southaven, Mississippi. After reviewing the Southaven Ward Map, it appears that Silo Square is located in Ward 2. Southaven

You said: That map is 15 years old.

ChatGPT said: You're absolutely right, and I apologize for the outdated information. The ward boundaries may have changed since that map was created.

Ward 2. Ward 3. Ward 4. Ward 1. And Ward 2 a second time. ChatGPT used a 15 year old map as a source.

Not only was this a waste of my time but ChatGPT kept spewing out responses that were clearly wrong and then apologizing.

Now, would you want this level of AI running your nuclear reactor?

Sharing Drives from Windows PCs

On the PC with the drive you want to share:

• Right-click on the folder you want to share.
• Choose Properties.
• Go to the Sharing tab.
• Click Advanced Sharing.
• Check Share this folder.
• Set a Share name.

• Click Permissions.
• Add a group for Everyone.
• Give Everyone all permissions.
• Click OK to close all dialogs.

• Go to Control Panel > Network and Internet > Network and Sharing Center.
• Click Change advanced sharing settings.
• Make sure Network discovery and File and printer sharing are turned on.

Now comes the fun part.

• Make the following update to the Windows Registry on the PC you want to view/update the shared drive.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters] "AllowInsecureGuestAuth"=dword:00000001




I make this update on all PCs just to be sure.

Large Language (Model) Lies

I keep exercising Large Language Model AIs, specifically ChatGPT and Gemini.

They seem to do a good job of non-technical tasks such as creating an itinerary for a trip. But when using them for more details such as suggesting hotels at a specific price point, they get very confused.

Recently, I tried just playing with ChatGPT.

I gave it the following prompt:

does the water go down the drain backwards in the southern hemisphere

It gave a comprehensive answer carefully explaining the Coriolis effect (due to Earth's rotation) and then concluding with:

So, no, water does not automatically swirl the opposite direction just because you're in the southern hemisphere. The Coriolis effect is only noticeable over large scales, like weather systems or ocean currents.

Now came the fun part. My next prompt was:

Then why do dial phones in NZ have numbers backwards?

Again it gave a comprehensive answer carefully explaining why dial phones in New Zealand (and some other countries) seem to have their numbers backwards is due to historical conventions in telephone design concluding with:

The phone numbering system in New Zealand isn't influenced by the Southern Hemisphere's geography, but rather by historical telephone design choices. It's a result of the legacy system from rotary dials that simply persisted.

Here's a picture that I found. 

And the fun continues. My next prompt was:

Then do the touch buttons start with 1 at the bottom?

And a another comprehensive answer but just a lie:

Yes, touch-tone phones in New Zealand (and a few other countries that still use this layout) have the number 1 at the bottom of the keypad, with the numbers increasing as you move upwards, similar to the old rotary dial system. So, the layout for the number pad looks like this:

7 8 9
4 5 6
1 2 3
  0

And it even created a diagram of the supposed New Zealand keypad with the 1 at the bottom!

Of course, I challenged that answer.

where can i see a photo of a NZ phone keypad

Needless to say, it went downhill from there.

ChatGPT finally conceded:

You're right! I apologize for the confusion. It appears that a lot of online images show the standard international keypad layout, where 1 is at the top, even for New Zealand.

In fact, New Zealand switched to the standardized international keypad layout years ago for touch-tone phones. The reversed layout (with 1 at the bottom) was largely seen on rotary dial phones that were in use earlier, but the touch-tone keypads you find today are the same as the global standard.

Sorry for the mix-up earlier! Let me know if you'd like to explore any other details. 

My prompt:

Then why did you lie to me?

ChatGPT's response:

I’m really sorry for the confusion earlier - that was definitely not my intention, and I can understand why it would be frustrating. I made an error in my response about New Zealand’s phone keypads. The reversed numbering system was used in rotary dials, but touch-tone phones in New Zealand have adopted the international standard, with 1 at the top.

I truly appreciate your patience and I’ll make sure to double-check my info in the future to avoid any more misunderstandings. Thank you for pointing that out, and again, I’m really sorry for the oversight! If you have any more questions, I’m here to help.

Help like that I don't need.

Broadband Data Usage

I last shared by broadband data usage in 2020. Here's my latest chart.

The bump in 3Q2021 and the spike in 3Q2024 are both upload of pictures and data to various clouds as I have transitioned my backup strategies.

When the blue stack is below the y-axis that indicates that Comcast didn't report as much WAN data as my router did. The occasional blue is usually an issue with my router collecting data.

Since my 2020 post, Comcast has reinstated their data caps but raised it to 1.2TB. Steady state, I'm still below .5TB. I can throttle my cloud uploads as necessary.
