I recently realized that I have developed a social media addiction. It's like a drug every time you get some kind of interaction or validation, for example a like on a comment, and there is a never-ending stream of distractions that can eat up so much time that could be better spent on the people closest to you, or improving yourself or your situation. So I made a difficult choice and about a week ago I deleted Instagram and TikTok from my phone. I'm not sure at what point I will ever go back to those platforms, but the compulsion to check them is already fading. If I do return at some point, I'm going to greatly reduce the list of who I follow, but at this point it is just easier to go cold turkey on all of it.

Home Screen Effect
Have you ever had that problem that you need something from another room in your home, and you go to that room, and instantly forget what it was you came for? And you can't remember what it is until you go back to the original room you were in? This is called the Doorway Effect, and it happens because your mind resets itself to focus on what is in the room that you just entered. The unfortunate side effect of this is that you might forget something important.
I experience something similar very often when using my iPhone, which I like to call the Home Screen Effect. I will often be doing something (not using my iPhone), and think about taking out my phone to do something, for example, search on the web, or take a note, or order something from Amazon, etc. Then I pull out my phone and wake it, and there is a notification, and I follow that notification and then forget why I brought out the phone in the first place. Or perhaps I open Safari and it is on a webpage I was looking at before and I get distracted by that. Or there is an unread badge on social media app that I open and get distracted by.
I even sometimes have this problem when using my computer if I have just context switched to it... I see a Safari tab from before and get distracted by that rather than doing what I need to do. I think there is a similar mental process when context switching into using a device to when we context switch into a new room. I don't remember this being an issue when I was first using the Mac many years ago, before the Internet and before multitasking. You would turn on the computer and open the application that you wanted to run and there were very few distractions because everything was so simple.
Similarly, before smart phones, when you wanted to make a phone call or even send a text message this problem didn't exist.
I think I need to figure out ways of changing my home screen to mitigate this problem.

Idea: Letterpress Tournament
I think the main elements that would make it different from current play would be the following:
1) time limit (either per turn or an overall Chess clock type limit)
2) no ability to consult the Internet or any other resources to come up with words
3) possibility of spectators/audience watching your game

Netflix Blu-ray vs. DVD confusion
I went into the DVD queue and set the format to DVD, and was surprised that they sent me a Bluray. I proceeded to try again on another sub account and the same thing happened.
So today I called Netflix customer support to find out what the deal is. Apparently they must have had a firestorm of complaints from people about getting DVDs of movies that have Blu-rays available. For example, if you added a movie to your queue and only DVD was available at the time, and then a year or two later they make a Blu-ray of it, it used to be that they would just send the DVD because that was the chosen format. Now, they *ignore* the format that you choose in the queue and just send Blu-ray always if available, assuming you have the automatically send Blu-ray option enabled.
In order to get a DVD of a movie that is in Blu-ray, you have to change to manually choose Blu-ray, which means each time you add a movie to your queue you have to pick the format. Or you have to turn the option back and forth whenever you want to get a DVD.
I can understand that there are customers that may want to always get Blu-ray but it seems to me that this problem could be much more easily solved in a way that would meet my needs as well as the "always Blu-ray" and the "mostly DVD, occasionally Blu-ray" folks.
Basically, they would just need to remember whether you had ever manually changed the format in your queue, and if so, respect that. The preference would simply set what your default format is, either DVD or Blu-ray. Then the list would indicate for each item in the queue whether it was DVD, Blu-ray, or Default (which could parenthetically indicate the preference, or that could be mentioned above the list once, or both).
You could very easily migrate people to this new setup by doing the following for all items in the queue which have a choice of format:
- For manual mode, all items that are set to DVD should instead be set to Default (DVD). Blu-ray items stay as Blu-ray.
- For automatic Blu-ray mode, all items are set to Default (Blu-ray), regardless of the setting in the queue because that is actually how things behave today.
If Netflix does not change to something like this, I think they need to change the presentation of the queue when you are in automatic Blu-ray mode, so you know that you never ever will get a DVD for any movie which has Blu-ray available... perhaps just don't show the popup menus at all and show things as Blu-ray, and have a link to turn off the option. Alternately, show popup menus with all of them having Blu-ray, and if you try to change it then it should prompt you to turn off the automatic Blu-ray setting.
Without one of these two approaches, the queue is very misleading because what it shows as the format that you will get is completely ignored in automatic Blu-ray mode.

How to use alternate from addresses with Gmail on iPad or iPhone
You need to set up your Gmail account as a generic IMAP account (not using the Gmail selection). Then simply copy a comma character, and then paste that into the address field and enter all your from addresses separated by commas.

More on dollar coins and modernizing US currency
I was able to get about $20 in Presidential dollar coins at the bank and so I filled up the top two slots with them. I've used them a few times so far and had no problems getting businesses to accept them. Since $20 won't last very long, I decided to order a box of $250 Thomas Jefferson dollar coins from the US mint. They have a special offer with no shipping charges to encourage more coins to be introduced into circulation.
I've talked about things which the US could learn from other countries before. Since then I learned about the Coin Coalition and Save the Greenback, two groups that lobby our federal government both for and against dollar coins. The Coin Coalition is mainly the vending machine industry, and Save the Greenback represents the Bureau of Engraving and Printing employees as well as paper and ink suppliers. I've also read that polls indicate that the public prefers dollar bills to coins. I suspect this is mainly due to ignorance. Most people have probably never seen the new dollar coins, and many think that "In God We Trust" was removed when it was really just moved to the edge. (The latest presidential dollar coins moved "In God We Trust" back to the front of the coin.)
Here's what I would like to see happen to modernize our currency:
1) discontinue the penny
2) stop printing the dollar bill
3) increase production of dollar coins
4) increase production of $2 bills
Doing #1 and #2 opens up space in cash registers to put dollar coins and $2 bills both of which exist and are underused. Eventually I think it would make sense to transition to $2 coins like the rest of the English speaking countries of the world have, but this would be an easy change to do now. Also, increased production of $2 bills might placate Save the Greenback somewhat. Getting rid of the penny will also open up space in pockets and purses for the dollar coin.
The Congressional Budget Office estimated in 2000 that switching from dollar bills to dollar coins would save about $500 million dollars a year due to the much longer lifespan of coins (30 years vs 18-22 months for bills). Getting rid of the penny would probably save some money as well. Printing more $2 bills could offset this somewhat, but that would be worthwhile to get us moving in the right direction. Perhaps after one successful bill to coin transition, the government would be more likely to see the benefit of a $2 coin.
If this transition ever happens, my Portsou will be fine because I can just put a stack of dimes where the pennies are today. This is how it is used in Canada. Also, if we ever create a $2 coin, hopefully it is just slightly larger than the current dollar coin in which case I could put it in the upper left slot where the Canadian $2 coin goes.

What to do when you get a chain forwarded email
Step 1)
Do not immediately forward this to all your friends/family/coworkers.
Step 2)
Skim the message enough to get the key idea and do a simple Google search to see if there are any web pages about this email. A good site to look at is snopes.com.
Step 3)
Assuming that the email is a hoax, misleading, old news, etc., reply to the sender (and optionally the other recipients) of this message about what you found. That will save everyone a lot of time.

Things the US could learn from other countries
Credit cards - Standardized PIN pads
In Australia and New Zealand, all PIN pads have the same layout of buttons and the sequence is always the same. Swipe/insert card, press button for payment type (cheque/savings/credit), then enter PIN or press OK. Additionally, they can use a PIN for credit card transactions which is quite convenient. US credit cards do not support this feature and require a signature.
Cash
Additionally, cash is much easier to deal with in Australia and New Zealand, for several reasons:
- include sales tax in advertised price - this leads to round number pricing on most items. It is very common for prices to be whole dollar amounts.
- no pennies - this one is a no brainer. Just round everything off to the nearest 5 cents (or 10 cents in NZ). Because of reason one above, this is often not even necessary.
- 50 cent pieces and 20 cent pieces - this reduces the number of coins you need to make change for a dollar. In NZ you only need 4 coins max - a 50, two 20s, and a 10. In Australia it's 6 coins - a 50, a 20, two 10s, and two 5s. In the US you need 11 coins - three quarters, a dime, two nickels, and 5 pennies. Almost half the coins in that scenario are pennies. Update: if you remove the constraint that the total be exactly a dollar you can do it with 10 coins: 3 quarters, 2 dimes, a nickel, and 4 pennies. That's $1.04 total.
- Dollar and two dollar coins - we have dollar coins and two dollar bills in the US but they aren't really used much for some reason. This is silly because we end up having to replace one dollar bills often due to wear. Coins last much longer than bills. Additionally, the two dollar coin allows you to make change for a 5 with just three coins - a one dollar and a pair of twos.
- 50 dollar bills - when you withdraw cash from an ATM in Australia or New Zealand, some or all of it comes in 50s. Any business will commonly make change for a 50, even for a small transaction. In NZ, you get a mix of 20s and 50s from the ATM. When dealing with $300 it is really nice to have less bills - six/nine instead of 15 in the US.
- Plastic money - leave it in a pocket and send it through the wash - no worries.
- Different color for each denomination - we are moving this direction with the new versions of bills but in other countries each bill is fully a different color rather than just green tinted with some accent. Makes it easier to distinguish and sort bills.
I can understand the barriers to change on this, but the metric system makes so much more sense. It seems to be intelligently designed rather than random or haphazard iike the Imperial/statute/whatever system that we have.
In addition to making things hard on ourselves dealing with unit conversions, we have to adjust to metric when traveling.
Not to mention our low performance in science education and trade deficits with the rest of the world... I have to think that switching to metric would at least improve our situation.

How to set up port mapping for iChat video chatting





Saturday, November 15, 2008
Time Capsule update
On the Time Capsule, I had to set up port mapping to match the previous configuration of the LinkSys. I also set up static DHCP mappings to match what was already set up. Enabled PPPoE client and DHCP server.
LinkSys changes:
- reset to defaults
- disabled WiFi
- disabled internet/WAN connection
- disabled DHCP server
I also needed to connect one of the LAN ports of the LinkSys to one of the LAN ports of the Time Capsule.
After setting all this up, I noticed the AirPort menu extra started showing the connected time for the PPPoE connection, which is a bit annoying. Luckily I was able to figure out that you turn this off from a submenu that shows up from the network name in the AirPort menu.
Another discovery I made was that with Leopard it is now possible to have multiple computers on the home network set up to do video chats. The secret was to map different incoming ports to different computers. In Leopard, iChat will try port 16402 and then continue trying lower port numbers down to 16393. Given that the Time Capsule is more flexible with port mapping, it was easy to set aside 16401 and 16400 for the laptops, while leaving all the old iChat ports for the Mac mini.

Already Voted
This election is the first time I am actually turning in my ballot before election day, however. Kathy and I went through the propositions today and made our decisions. It's tough when there are 12 statewide propositions and 4 local propositions. Seems like we are doing the legislature's job for them sometimes.
In the end, I voted no on most of the propositions, though I did vote for a few. I also found a cool new website called Ballotpedia with lots of information for anyone who hasn't voted yet.

How to transfer local Time Machine backups to Time Capsule
1) Connect the external hard disk and the Time Capsule (via gigabit Ethernet) to the same computer.
2) Complete a backup to the hard disk, then turn off Time Machine while doing the conversion.
2a) If you have other computers backing up to the same hard disk, make sure those have a current backup as well before continuing.
3) Unmount the external hard disk.
4) In Disk Utility, create a new disk image from device from the external hard disk. Select the partition rather than the whole disk. I saved the image directly to the Time Capsule. This will take a long time. In my case, it took over 12 hours.
5) Unplug the external hard disk.
6) At this point, you have a .dmg with the complete contents of the external hard disk. This needs to be converted to a .sparsebundle image. This can be done using "hdiutil convert -format UDSB harddisk.dmg" on the command line. The sparse bundle will be smaller than the .dmg since free space is not copied into the sparse bundle image. In my case, I had enough space on the Time Capsule to fit both images at the same time.
6a) After the conversion was completed, I removed the .dmg file, and made another copy of the .sparsebundle. This is because I was backing up both my MacBook and Kathy's MacBook to the same external drive. In a single computer case this is not needed.
6b) Next, the two images need to be fixed up to only contain the relevant files and free space on the Time Capsule. I mounted each image and deleted the inappropriate set of backup files. This seemed to work best dragging the top level folder under Backups.backupdb to the trash and then doing rm -rf in Terminal on the files. Emptying the trash might work as well but seems to be slower.
6c) After removing unneeded files, to free up space on the Time Capsule, unmount the disk image. Then run "hdiutil compact image.sparsebundle" in Terminal. This will remove unused band files from the sparse bundle.
7) Configure Time Machine to use the Time Capsule and start a backup. Once a disk image is created, stop the backup. The image should be named <computer>__<uuid>.sparsebundle. Remove this image and rename the sparsebundle you created to match the name. Then do a backup again. You should still be doing this over Ethernet.
8) After the first backup, wireless backups should be fine.
The only other consideration is that the image size may not be correct (500GB vs. 1TB), but I don't suspect to run into that limit any time soon, and it is easy enough to resize using hdiutil.

Time Capsule arrived
So far I am liking the Time Capsule. Right now I have it set up in bridge mode and am still using the LinkSys WRT54G as the main router. Here are some of the tradeoffs between the two routers:
* Time Capsule has a built in hard disk which can be used for wireless backup
* Time Capsule supports USB printer sharing (thinking of moving the inkjet printer to be shared this way - it's currently shared by the Mac mini)
* LinkSys supports dynamic DNS which I am currently using... Time Capsule supports Back to My Mac, but doesn't seem to support dynamic DNS
* LinkSys has 4 100Mbit ports plus 1 uplink port, Time Capsule has 3 Gigabit ports and 1 uplink port
* LinkSys is 802.11g, Time Capsule is 802.11n
* Time Capsule requires a reboot for any configuration change, which takes 30 seconds or something. Config changes on the LinkSys happen much faster.
Overall, I think I should be able to totally replace the LinkSys with the Time Capsule, but the first challenge is to transfer our last 9 months of backups over to the Time Capsule. This is not as simple as you might think because the Time Capsule needs backups in sparsebundle disk image format, and the backups we have are just stored as files on the hard disk directly. I have an idea for how to get this working which is taking a while. If my plan works I will post an update on how to do it for anyone who's interested.

Thanksgiving preparations
Also, is it just me or is it really, really annoying that everyone seems to have forgotten about waiting until the day after Thanksgiving to start the Christmas music and decorations? In some cases, Christmas stuff was out even before Halloween.

Recent upgrades
The upgrade turned out to be both easier and harder than I expected. Getting the top case off was fairly easy, but dealing with the bluetooth and AirPort antennas and the plastic cage that holds the optical drive and hard drive was harder than I expected. Still it didn't take too long and now the mini is running nicely from the internal hard disk.
The other upgrade I did recently was to switch over compact flourescent bulbs from incandescent for most of the lights at home. The 60W and 40W equivalent bulbs work pretty well now (come on instantly, no noise, soft white light). And, they aren't that expensive. A 4 pack was about $7 at Home Depot. This is still more than conventional incandescent bulbs, but the 75% savings on power consumption and longer life end up making them cheaper over the life of the bulb. And less power consumption is better for the environment given that a large percentage of our power is generated from coal power plants.
The only remaining lights that are still not CFL or regular flourescent are two 75W flood lamps on a dimmer switch and a 30/70/100W 3-way bulb in the lamp by the bed. I have yet to find a 3 way CFL that is anything other than 50/100/150W equivalent, which ends up being really huge to be able to put out the top light level. That would be fine except it won't fit in the lamp I have. Dimmable flood CFLs exist as well but it looks like they may not fit exactly in the track light fixture I have.
