Facebook changes - Pages and identity shifts, Groups going

The people I read don't write about Facebook, so I have to figure it out on my own. Since FB doesn't communicate very well (irony overflows) that can be challenging.

A few things I've noticed lately ...

  • If you own "Pages" you can now switch Identities between being the "Page Owner" and your own identity. The right side identity item has a drop down. I think this may only work for new Pages at the moment.
  • "Groups" are only a shadow of their former selves. There is still support for legacy groups, but you can't create new ones of that style. The new "Groups" are the equivalent of mailing lists limited to personal friends.
  • It's easier to create a Page. There's much less emphasis on proving ownership of an entity or organization -- which is interesting. It's now buried away in a TOS dialog.
  • You can now set FB to use https.
  • There's an occult account setting to disable use of your name in ads targeted at your "Friends".

FaceTime: AutoAnswer, URL, desktop 1 click call

FaceTime for Mac ($1) has an undocumented AutoAnswer feature ...

10.6: Enable AutoAnswer in FaceTime for the Mac - Mac OS X Hints

... defaults write com.apple.FaceTime AutoAcceptInvitesFrom -array-add +15205551212

... defaults write com.apple.FaceTime AutoAcceptInvitesFrom -array-add email@email.com ...

... defaults delete com.apple.FaceTime AutoAcceptInvitesFrom ...

The author used the "strings" command to uncover these options.

I've been looking for this for years [1] (die iChat die!), so, even though I generally avoid undocumented terminal entered preferences, I immediately set this up on my home iMac. I set it to AutoAnswer calls from my iPhone. Then I started up FaceTime and turned my screensaver on (screen is then locked) and placed a call.

With FaceTime on, a green light showed next to my iMac's "iSight".

The screensaver didn't change, but my desktop answered. My phone displayed the video input from the desktop and audio worked.

A few things to keep in mind as you test this ...

  • Preferences are user specific. On a multi-user machine you have to enable it separately on each account.
  • If FaceTime isn't running nothing happens.
  • If the FaceTime window is showing the user gets a brief opportunity to cancel the call.
  • If the FaceTime window is hidden it will answer, but there's no UI indication that a video chat is working.
  • You can configure FaceTime to run on startup.

I'll be testing this out over the next few weeks, then I have to see if I can persuade my elderly parents that this is something worth enabling on their Mac. It would require an upgrade to 10.6, I think I'd left their machine on 10.5.

For an elderly user, or for anyone who wants a very simple way to create call you can create clickable desktop shortcuts or links in a web page ...

In Safari's address bar, type in one of the following URLs:

  • facetime:// appleid
  • facetime://email@address
  • facetime://phone#

... select that URL in the address bar and drag it to the desktop.

When you do this you get a very dull file. Use IMG2ICNS (Free) to turn a photograph of the person you want to call into the file icon. I did this for my mother then put the icon with my picture on her desktop.

[1] Google could never come up with a decent control UI for Google Video Chat.

PS. When reviewing some of these old links, I was struck by how many years we've been trying to get useable 1:1 videoconferencing on the net. We're talking at least 13 years of repeated failure, with only modest recent success with Skype and Google Video Chat. Apple has failed repeatedly. I wonder if this time they'll push it through, but I've thought we were close before.

My MagSafe adapter light goes out periodically

My T-Connector style MagSafe LED (green light) goes off periodically. Disconnecting and reconnecting the T connector will turn it back on.

This Apple support note was written for people like me...

Apple Portables: Troubleshooting MagSafe adapters

...Whether your product is in or out-of-warranty, you can take your adapter to an Apple-Authorized Service Provider or Apple Retail Store for evaluation and replacement if necessary. You may be eligible for a replacement adapter free of charge provided there are no signs of accidental damage...

I've inspected and cleaned the connector. For now I live with it, but if it gets worse I'll have it replaced. Sounds like an understated semi-recall ...

Update 3/6/11: It seems to be fixed, or at least a lot better. I guess it just needed to be cleaned.

The black YouTube screen problem and the HTML 5 workaround

My 11yo got a "black rectangle" for all YouTube videos today. This is popularly known as the YouTube "black screen" problem, and Google's own engineers say ...

why do Youtube videos no longer load on Firefox? - YouTube Help

... Our engineering team has been working on this for a while. We haven't been able to identify the source of the problem yet, but the details you've provided have really helped...

It's a Flash problem, but it's not Firefox specific. It can strike any Flash-based browser. What a surprise that Flash should have a bug that even Google can't fix ... :-).

There are many Google hits on this problem, but of course there's no fix. The problem comes and goes.

I found that if I took the "embed" URL and opened it in Safari that the video would play. So it's related to YouTube's default video presentation. Upgrading to Flash 10.2 didn't help.

What helped was forcing Safari to load the HTML 5 version of the video. There are several ways to do this

I ended up doing the last one, and I set the options to default to 720p. It works.

My next step would have been to install Chrome, which has both WebM and a Google-authored Flash player.

PS. Ben says it "looks cooler" now.

Update 2/20: See comments for other ways to work around this. Windows 7 is also affected. I'm seeing Flash 10.2 problems on many sites, I suspect there are hardware acceleration problems with older hardware configurations.

Managing spam text messages on the AT&T iPhone

AT&T doesn't provide a way to block spam text messages. They suggest signing up for a $120/year service that enables number blocking.

Yeah, mobile phone companies are pure Satan.

AT&T does provide a reporting service:

Answer Center | AT&T - What should I do if I receive spam text messages on my wireless phone? ...

To report spam text messages to AT&T: When you receive text spam, forward the whole message to short code 'SPAM' (7726) from your wireless device. There is no charge to report mobile spam. Messages forwarded to 7726 do not count toward your data usage or voice package.

To this on the iPhone you

1) view the SMS text message conversation

2) tap EDIT at the top of the screen

3) check off the message(s) you'd like to forward

4) tap FORWARD at the bottom right of the screen

Problem is, this only forwards the message, not the sender number. When you submit AT&T replies with a request for the sender number. I had to inspect my incoming message list to find that, and I couldn't copy paste. I had to do the old memory/pencil thing.

RIP Password - Google's two factor authentication

Google is rolling out comprehensive mobile phone based two factor authentication to regular Google accounts ...

Official Google Blog: Advanced sign-in security for your Google account

... If you like, you can always choose a 'Remember verification for this computer for 30 days' option, and you won't need to re-enter a code for another 30 days. You can also set up one-time application-specific passwords to sign in to your account from non-browser based applications that are designed to only ask for a password, and cannot prompt for the code....

Some notes from the help page (emphases mine, square parens my comments)

... Soon after you turn on 2-step verification, non-browser applications and devices that use your Google Account (such as Gmail on your phone or Outlook), will stop working. You'll then have to sign in using your username and a special password you generate for this application...

... If you have an iPhone, iPod or iPad, [3G or later, needs iOS 4] we recommend you use the Google Authenticator application to generate verification codes. The application doesn't require an Internet connection or mobile service to generate verification codes. If you would prefer to receive your verification codes by text message or phone call, follow the directions for Text or voice message below....

... Adding a backup number ensures you can receive a verification code to sign in even if your primary phone isn't available or working. ...

... After you set up your phone to receive verification codes, you will be given 10 backup codes. These backup codes can each be used once each to substitute for a verification code. These could be useful whenever you don’t have access to your phone (for example, while you are traveling)...

... If you've lost access to your phones, you can always sign in using one of your printed backup codes [and then turn off two factor authentication?], which you generated when you first turned on 2-step verification. If you've lost your phones and don't have your backup codes, you'll need to fill out an account recovery form...

... An application-specific password [revocable] is similar to a verification code in that you don't have to memorize it. However, application-specific passwords are longer than verification codes and you do not enter them into web browsers. In addition, you do not get application-specific passwords from your phone -- instead, to generate an application-specific password...

Visit the Authorizing applications & sites page (pictured below) under your Google Account settings...

Soon it will be safe to use my Google services on untrusted (keystroke logger possible) machines -- like my office XP box. I'll configure my trusted machines to remember verification. My iPhone will run an RSA-token like authentication code generator. I will keep at least one backup code in my wallet - albeit in a permuted form.

Of course I will wait several weeks before I switch over. I'm no fool. I'll let the brave and inexperienced take the arrows of early adoption.

The traditional password isn't quite dead yet, but it has one (rotted) foot in the grave.

Thanks Google. Special credit for making Google-authenticator open source and standards based ...

The Google Authenticator project includes implementations of one-time passcode generators for several mobile platforms, as well as a pluggable authentication module (PAM). One-time passcodes are generated using open standards developed by the Initiative for Open Authentication (OATH) (which is unrelated to OAuth).

These implementations support the HMAC-Based One-time Password (HOTP) algorithm specified in RFC 4226 and the Time-based One-time Password (TOTP) algorithm currently in draft.

10 Minute Mail - a disposable email address

10 Minute Mail gives you a temporary email address on demand. Good when you're forced to provide an email address for product registration or to deal with some other marketing-inspired blackmail. I suppose it's also useful for criminal activity.

Personally I have a yahoo.com address that is purely used for junk mail. That works fine; I set the spam filter to the highest setting and it still seems to work. Makes the marketing droids happy, they think it's worth something. If 10 minute mail really caught on then email traps would refuse to accept it.

Using OS X Spaces, Expose, Minimize and Hide - best practices 2.0

I'm an old dog. It takes work to change my habits. A year ago I took a look at how I use my OS X workspace: Using OS X Spaces, Expose, Minimize and Hide - best practices.

Since then I've switched all my machines to 10.6. This is what I do now (I use two displays):

  • I've given up on Spaces. It almost works, but some multi-window apps get scattered across Spaces. Even when it works, it's not quite right. Even in 10.6 it fits poorly with Expose, Minimize, and Hide. I think Apple has given up too; the newest keyboards have a labeled shortcut key for Expose, but not for Spaces. I now use Spaces only when I'm running Fusion -- it gets its own Space.
  • I love 10.6 Expose. There are four things you need to know
    • If you click-hold on an app's doc icon Expose shows only that app's windows
    • If you show all windows in Expose, then click on an app's doc icon, you see only that app's windows
    • With 10.6 minimized windows show up in expose in their own row
    • Hidden windows do not show up in Expose -- unless you click on the app's doc icon. Then they are forced to appear.

With 10.6 I recommend ...

  • Learn Expose.
  • Use minimize and the "grow" button [1]
  • Don't use Spaces except for unusual cases such as running a VM. I might try using my 2nd Space just for Aperture.
  • Don't use Hide and Hide Others. They are legacy functions left over from Mac Classic. They don't mesh well with Expose.

[1] The "grow" button is problematic. iTunes is completely non-standard for minimize and grow (need to hold opt key to get correct behavior), and many apps simply expand to the entire screen instead of following the "grow to best size" algorithm.

Reeder and Reader change how I read the NYT

My Google world editions experiment has a B grade so far. It's not bad, but Google's news algorithms underrate the NYT and the Guardian. I get too many 2nd and 3rd tier news sources.

Fortunately, my favorite Google Reader iPhone client [2] has changed the way I access the NTY. Reeder.app has integrated Arc90's Readability.

Why does this matter? It matters because the NYT's feed posts are not full text. They're simply pointers to the web articles and they are not mobile-optimized. Byline, my previous iPhone GR client, used to cache these articles [1] so they were fast to display, but Reeder doesn't. Until recently I used Reeder's integrated Google or Instapaper mobilizers to read NYT articles, but that stopped working.

I could use the NYT's iPhone app to read the NYT, but that's a source-specific workflow. Worse, the NYT iPhone app doesn't integrate with my Google Reader shares.

Now, however, Reeder with readability works perfectly with the NYT. To the NYT it looks like I'm fetching pages via a browser, but Reeder's readability function post-processes the page so it renders perfectly on my iPhone.

Screen shot 2011-01-22 at 2.41.30 PM.pngMy NYT workflow starts with the NYT RSS resource page. From there I added about 10 feeds to Google Reader. Individual feeds belong to any of several "folders", but they all belong to an "NYT" folder.

In Reeder.app the articles show as short titles and introductions. By tapping a small icon, or using a spread-finger gusture, I tell Reeder to load the entire article using Readability. From there I can share via Google Reader Shared Items or add notes. Those shared items, in turn, go into my twitter stream. (Typically with truncated annotations. I'm not among those who praise Twitter's insane string length limits).

It's a far better workflow than using the NYT iPhone app. Recommended.

[1] I'm not sure the NYT allows this any more.
[2] There's an iPad client too. A Mac OS X client is in beta, but on the desktop I typically use Google Reader's native web interface.

The surprisingly quiet OS X App Store: I buy iWorks' Numbers.app

I'd been considering buy iWorks for a while. I've been particularly interested in Apple's Numbers.app, as I don't have a desktop spreadsheet on my Macs and I don't want to install Office. I've been using Google Spreadsheet for a few years, but that's an annoying experience. I've also considered Mariner Calc, but it seems a lost (noble) cause given the growth of iWorks [1].

I was going to wait for the next version of iWorks, but with the OS X (Apple) App Store launch Numbers is sold separately for $20. I decided to combine a Numbers purchase with a visit to the App Store. Along the way I picked up Spanning Sync's Contact Cleaner for $5 (recommended). Here's what I learned.

I'll dispense with Numbers first. On initial testing, Numbers feels like an OS X version of AppleWorks' spreadsheet. Some of the UI elements are bizarre. It includes data filters, for example, but the data filter checkbox is grayed out until you click the "+" control to the right of the criteria entry fox. Clearly this was not built by Apple's A team.

Numbers will import from Microsoft Excel, AppleWorks 6, CSV, tab delimted and Open Financial Exchange (OFX) format. It exports as Excel and CSV (amazingly, not Apple's longstanding tab delimited format). The installer does not include a user guide, but there's a help file link to Apple's user guide download site. I expect the DVD version of Numbers has more templates and examples than the App Store version.

Numbers is probably worth about $20, especially if it works for Emily. It's not worth more than that given its proprietary file format.

Numbers is worth $20, that is, depending on its DRM. This is the interesting part of the Apple Store. How does the DRM work?

You purchase an app from the Apple OS X App Store using your iTunes account. You don't get an installer. Installation is managed by "App Store.app". There's no "uninstall" documentation in the associated help function or anywhere on Apple's site (drag package to trash basically). If you change machines you're supposed to authenticate to the App Store using your iTunes credentials and reinstall. If you want to install on multiple machines (apparently supported by the DRM, Darwin knows what the EULA says) you authenticate and install on each.

The installer has no progress indicator. It feels like it's a very early beginning, which is typical of new Apple products. If you click on the "Purchases" icon you will see a progress bar (137MB download) [2].

The installer places the app into the Global "Applications" folder, not the user Applications folder. It is available to all accounts on the host machine. I don't know if vendors can change this. As an experiment, I zipped up the Numbers.app package from my Applications folder and copied it to a 10.6.5 machine that didn't have App Store installed. It ran there without complaint.

I also tried copying to a G5 running 10.5. It didn't work on this machine. Whereas iWorks '09 supports the G5 (universal app) the Numbers.app downloaded from the App Store is Intel only. This isn't an Apple problem of course -- Apple doesn't license these apps to be installed outside of the App Store, much less on a G5. Still, there are, for now, some advantages to buying Numbers on the DVD.

For the moment then, the app store Numbers.app DRM is light. Even if Apple vanished next year, you could still use Numbers. Unlike, say, what happens to Google's Documents when Google vanishes someday. Of course this is likely to change, and there are probably options to make the DRM controls tighter even with the current store.

In bullet form, some further impressions of the Jan 2011 App store

  • Vendor pricing is largely unimpressive. It's usually identical to retail. Yes, I'm looking at you, Omni Group! Considering the DRM uncertainties and installer absence most geeks will want to buy direct. Of course since Apple takes a 70% cut ...
  • Apple's prices are price competitive. Apple's 70% overhead goes to, you know, Apple. I like the unbundling of iWorks and iLife. Since Apple doesn't offer upgrade discounts on most products the App Store versions are interesting. Of course there's no installer, no universal apps, probably fewer templates, etc. Still, for Apple products the App Store is interesting.
  • The $80 new user price of Aperture is aggressive (it's about the upgrade price for current users). Be warned, however, that Aperture is not iPhoto Pro. Apple is slowly turning Aperture into iPhoto Pro but there are still missing data structures. If you migrate, for example, you lose all your Album and Event annotations. At Apple's current lethargic pace they are probably 3 years away from turning Aperture into a true iPhoto upgrade. (Sure, they market it as an iPhoto upgrade. Did you know Apple lies?)
  • I did see a few interesting utilities and, of course, small games. We all expect to see more OS X versions of iOS apps distributed this way, but there aren't many yet.
  • In general the app store felt sparse and quiet.

What's in the App Store?

  • Apple's consumer products and Aperture (which used to be "Pro" but is slouching towards being, maybe one day but not yet, iPhoto advanced).
  • Printshop 2 by Broderbund (Wow. Still exists.)
  • World Book encyclopedia for $30
  • Omni Group products, all at list price
  • MarsEdit
  • TextWrangler and BBedit
  • Yojimbo
  • Spanning Sync utilities (I bought Contact Cleaner for $5)

Apps that aren't there (yet)

  • Rogue Amoeba: Their wonderful apps help us do things like capture streaming audio. Not supported by Apple!
  • Apple's professional market products
  • Mathematica: Probably too expensive
  • Filemaker apps: Pro and Bento. This surprised me. Are they just not ready? Do they violate guidelines? Is the 70% cut too harsh?
  • Nisus Writer Pro: It's on the way, but not there yet.
  • Most of Mariner's software
  • Adobe products
  • Microsoft products
  • Many of the interesting niche market information management apps

I suspect that the smaller vendors are going to come along, but the price advantage for Apple products is harsh. Few will be able to compete with that. [3]

[1] iWorks, of course, has completely proprietary file formats. The only saving grace is that many files embed PDF in the package structure, so perhaps we can dig out the PDF and interpret the data after Apple disappears in 2027. I fear the battle for open file formats has been lost. Sometimes the good guys go down, but there will be many replays in years to come. For documents I use Nisus Writer Professional, despite its clumsy handling of images (no $#@! compression?!) and worthless HTML export. The default RTF output is as close to a standard file format as 2011 provides.
[2] I've read that the file that download is an installer, but it's hidden and deleted after installation. It doesn't go the trash.
[3] Eventually this may get them into European antitrust issues.

Update 1/30/11: There is more to Numbers that I realized. One of the big limitations of Excel is that you your print surface is your worksheet. In Numbers worksheets are distributed on the print/view workspace. That is a big improvement. I need to do a separate post on Numbers.

How I synchronize OS X Contacts with Google Contacts and my iPhone

Abandon all hope, ye who enter here. Dante.

This one is for Martin.

I have synchronized my OS X Address Book entries with Google Contacts and MobileMe/iPhone for over a year. It mostly works. This is how I would do the Google Calendar part of it if I were starting out today. The MobileMe stuff is relatively easy [1] and I won't describe it further.

Before I begin, however, I require any reader to pass through three gates of informed consent ...

Gate 1. “Do I feel lucky?” Well do ya, punk?

If there's anything in this post you don't understand, you shouldn't try this. It could blow your Address Book apart. You might spend months reassembling it.

Gate 2. Read my 2011 resolution on managing complexity.

This is on the premature adoption end of things. It's taken about twenty years of boring, career destroying committee work to develop an incomplete and flawed standard sharing calendars and invitations. We're ten years of pain away from a similar standard for exchanging contact information.

Gate 3: Scan my Synchronization is Hell post.

Ok, you're informed. If you proceed, as a fringe benefit, you may come to understand why healthcare, a trillion dollar industry, seems stuck in the dark ages of IT. If it's hard to get address books to communicate, how much harder is it to send patient records from system A to system B? You may start to understand things like Halamka's post on a "Universal Exchange Language" for healthcare (heavens, but he's an optimist).

I use OS X Address Book as the "source of truth". That's where I add new addresses, and that's where I define what gets pushed to Google. If most of your contacts are in Google you would take a different approach.

Step 1: Buy Spanning Sync's Contact Cleaner ($5, App store) and try Spanning Sync ($25 a year, $20 if you use my referral code NXC8PS, 15 day free trial). I don't use it sync calendars, just contacts.

Step 2: Back up Address Book. Then use Contact Cleaner to clean it up; note warnings about unusual suffixes and the like. Sync works best with a first name, last name for individuals (no spaces) and a string (with spaces) for "companies".

Step 3: Define a group in Address Book that you'll sync to Google Contacts. Start small and build up. I call mine "Google Sync. Configure Spanning sync to only sync that group:

Screen shot 2011-01-15 at 11.00.46 AM.png

Step 4: After sync used Contact Cleaner again. Try a few reps until you're no longer getting duplicate or messed up contacts.

Step 5: As you use Google, keep an eye out for duplicates. Use Google's merge tool opportunistically. It works well, better than OS X Address Book merge.

Step 6: Over time add more names to the Address Book Google Sync group. Until you've got every address you care about synchronizing.

- fn --

[1] Apple controls both data models and they're roughly congruent, at least if you're on 10.6.6. I don't sync via iTunes because I already own MobileMe and it lets me sync to my accounts on multiple machines. The rest of my family can't sync directly because we all share one iTunes account, they have to sync to MobileMe and separately to their OS X accounts on multiple machines.

Spanning Sync contacts cleaner - a quick review

I bought Spanning Sync's Contact Cleaner for $5 from the OS X App Store.

I've used their flagship product for years to sync my OS X Address Book to Google. It's relatively expensive ($25 or so a year) but it mostly works. Since synchronization between differing data models is an impossible problem, "mostly works" is excellent.

So I was willing to give this utility a try.

Briefly, for an early product, it works pretty well. It has a few bugs, but it's definitely worth $5. The app offers to make an Address Book backup on 1st use -- that's a good idea.

I'm a pretty good test case because

  • I sync my OS X Address Book to both Google (Spanning Sync) and MobileMe
  • I have over 800 cards in my personal book (more in my separate corporate directory)
  • I routinely define a "Family" as a "Business" to get around the first name, last name problem.
  • For individuals I often link them into "Families" by use of the "Business" field to hold a family name (or, in my case, the domain name for our family)

These are the bugs I found:

  1. If you choose open in Address Book, then change type from individual to business in Address Book, Contact Cleaner will crash
  2. Details view for "one name" errors omits email addresses
  3. Details formatting not always optimal
  4. Can't manage the individual to company conversion

I'm also a bit suspicious about how it manages group memberships when it merges or alters contacts. This may just be my paranoia coming out.

Some advice on using Contact Cleaner

  • Turn off all other sync while using this tool. I sync my OS X Address Book to both MobileMe (and thus to my iPhone) and to Google Contacts [1]. Just disable your network connection.
  • If you edit in the Address book, save your changes (click out of edit mode) then Rescan in Contacts Cleaner. Otherwise it won't pick up your edits.
  • I like to make changes in Address Book then rescan - gives me more control and I can see the full results
  • Be wary if you use non-default Address Book fields. This kind of cleanup is a very hard problem.

[1] I sync a selected subset of my entire Address Book to Google Contacts. I create new addresses in OS X and then let them sync to Google. Once they sync I can safely make smaller edits on either side (esp. email address updates). I can also do merges safely on the Google side. Group assignments are independent. I define a "Family" entry as a type of "Business", that seems to work.

iTunes PDF books won't sync to your iBooks app?

You are frustrated.

You can drag and drop PDFs to the iTunes Library icon (iTunes open). They get organized into the Books section. They seem to sync to your iPhone (iPad). Except they don't. Nothing shows up.

You've tried everything. Maybe even inspected permissions.

Try this.

Open iBooks.app.

See that lovely little button that says "Books"?

Tap it.

Now you see your PDFs.

You are welcome.

PS. You can create a collection called "All" and, using Edit, tap on items, then tap Move you can put your Books and PDFs together.

Authenticate your Google Apps email - and help finish email spam

The web is overwhelmed by splogs and garbage sites full of noiseware (emphases mine) ...

Why We Desperately Need a New (and Better) Google

... Content creation is big business, and there are big players involved. For example, Associated Content, which produces 10,000 new articles per month, was purchased by Yahoo! for $100 million, in 2010. Demand Media has 8,000 writers who produce 180,000 new articles each month. It generated more than $200 million in revenue in 2009 and planning an initial public offering valued at about $1.5 billion. This content is what ends up as the landfill in the garbage websites that you find all over the web. And these are the first links that show up in your Google search results.

Google is falling, because it's trapped by its own business model.

It looks bad, just as bad as email spam was just three years ago. Today, though, email spam is dying.  The cure was clear by the late 90s, but it's taken ten years to really work. The answer was differential filtering based on the managed reputation of an authenticated sending service. Today we call that Domain Keys Identified Mail or DKIM. DKIM doesn't identify the sender, it identifies the sending service. The sending service then assumes responsibility for the sender (they know who the sender is). If the service doesn't police its users, it gets a bad reputation -- and starts being filtered aggressively.

Gmail accounts have used DKIM for a while, but Google Apps email has made do with SPF -- an inferior solution. Google has only now rolled DKIM out to Google Apps users. If you use Google APps you should enable this (it's not automatic yet). Without it the email you send will be increasingly "second class" and more likely to be filtered out.

It took about two minutes  activate DKIM for our free Google Apps family domain. We were able to use the automated method because that domain is managed through Google's Registrar partner - eNom. It sounds like it might be trickier to activate for domains managed by my favorite registrar/hosting service - DreamHost though I expect it will eventually be automatic everywhere.

We beat email spam. It wasn't that hard, though the fix did take a long time implement. It's clear we could do the same thing with garbageware sites. That fix, however, may require a company other than Google ...

Replacing a broken 3G iPhone screen: what iFixit doesn't tell you

I used the iPhone 3G Front Panel Assembly from iFixit $70) to successfully replace a broken 3G iPhone screen. I followed the iFixit assembly directions, watched a video for a related procedure and improvised when both omitted critical steps.

You shouldn't try this. I estimate the average non-obsessive geek has a 50% chance of ending up with a fixed phone, a 30% chance of ending up with a more broken phone, and a 20% chance of ending where they started less $70 or so. Once you do this successfully once the odds of success increase dramatically, but the learning curve is steep. If you insist, then please read this post carefully. It will boost your success rate to 75%.

I recommend finding someone who's done this before and paying them to fix your phone. Or see how much you call sell the broken phone for, the buyers will easily fix it. Or buy a 3G display assembly instead ($100) and avoid about 30% of the repair hassle.

I did not attempt the $40 front panel procedure. iFixit rates that as "difficult". In English this translates to "impossible".

Lastly you can pay Apple $200 and they'll do a perfect job. Keep in mind that a new 4G iPhone costs about $700 out of contract and a new working 3G is probably worth at least $350.

If you do proceed consider also replacing the battery at the same time. About half of the hardest steps are common.

I hope by this time you've stopped, but perhaps you're already committed. Or maybe you want to make a business out of this. That would make sense, especially for someone in college where broken iPhones must be common. Here's what I learned (this supplements, but does not replace, the video and the ifixit directions)

Ordering and shipping

  • The front panel assembly does NOT include tools. I missed that, because I started out looking at the insane option of the "front panel" only kit. You definitely need the plastic spudger. You could use a very slender flexible knife or a scalpel blade in place of the metal spudger. I had a magnetic 00 philips screwdriver, I don't know if their's is magnetic.
  • It's surprisingly hard, with a worn black 3G iPhone, to identify that it is, in fact, a 3G iPhone! Elders will need a magnifying glass.
  • The model numbers on Apple's site are only for the first batch of devices. I visited Apple's site and followed their external identifier directions.
  • The assembly came inside loose bubble wrap and a simple envelope; I'm surprised it made it.
  • The parts don't say Apple anywhere.

Preparation

Here's what I laid out. I was able to make up for the parts I didn't order, I had an old spudger that was fine. I think the screws are all the same but I had a different bowl for each and a picture of the step behind each bowl. The tweezers and compressed air were essential. The white paper is sticker backing to hold the cursed black tape removed during the procedure. I wish I had had a magnifying glass, but I'm 51. A bright light source should suffice for the under 40 crowd.

It took me about 2.5 hours to do this with several breaks when I ran into problems. An expert could do it in under 20 minutes.

iFixit front panel assembly directions

Read the directions very carefully several times and watch the video for the similar but harder front panel assembly. This is what they left out:

  • My panel came with a screw in place. Look for this and remove the screw. If you don't know this you'll discover the screw when you do the reassemby; and you'll have to take it all apart again.
  • The panel has plastic covers you'll want to remove only at the time of assembly.
  • The video is an edited series of cuts. It omits several key operations.
  • Reassembly is harder than disassembly.
  • I wore latex gloves (powder free) to reduce hand oils and sweat getting on things.
  • The relevant portion of the video is from about 1:13 to 2:06. Watch that several times, unfortunately key parts were excised.
  • Manufacturing changes over time. There are differences between the very first 3Gs and later models.
  • There are two forms of cable connection. There's a standard pressure join and there's the iPhone destroying FPC connector (see below). When reassembling you really need to visually line up the pressure connectors. It takes a modest push to seat them; you will then feel a soft but obvious "thunk". If you don't clearly feel this they're not really connected.

The treacherous black tape

  • Study this carefully before your remove it.
  • At one point you are instructed to remove some black tape. This is very hard to do, I had to work one end up. A scalpel might help. Use tweezers. The tape will curl; but mine curled in a benign way. Leave the curled loop on your paper. When you reassemble, either have someone hold the phone for you or put it in a clamp of some sort. I think the best approach would use a light locking clamp to hold the tape and tweezers. Reposition it, hold it in place, try to flatten it out.

The FPC connector

As of 1/2011 there is a key image missing from the assemblydirections at "step 6". if you haven't done this before you will have NO idea what is meant by the "PFC lock"

I have tried to capture it below, but I should have used a macro lens. It is that small. The PFC lock is a 1mm x 3-4 mm white bar that sits over the distal end of cable 3 as it emerges from a black connector cover. It is shown here in the unlocked, upright position. A simple flick of the plastic spudger will flip it up. Then cable 3 will slide out.

To reinsert cable 3 I suggest using fine tweezers on the black cable sheath to push it into the black housing above until the white line on PFC cable is about at the proximal side of the black cable cover. Then flip the PFC lock down.

Good luck.
