OS X Preview PDF display - it has limits

Montreal offers a detailed PDF map of the island ..

... See this Google map of the metropolitan area or download the incredibly detailed city map (pdf format) from the Montreal transit site ...

It's a richly detailed 4.4 MB pure vector PDF.

I tried viewing it in OS X Preview.app. Not such a good idea. Preview pegged my MacBook at 98% CPU and a GB or so of memory.

This is the first time OS X Preview has disappointed me. I hadn't realized it was such a light duty application. I'm contemplating installing Adobe's product, something I try very hard to avoid given Adobe's astounding record of installer dysfunction.

Using Google Voice when traveling internationally

When we visit the old country (Canada) I put my AT&T iPhone in airport mode. So no cell services and no data services. It will work in Canada, but even the voice charges are prohibitive.

So what do I do about for people calling my cell phone while I'm away? How should people from work get in touch with me?

Enter Google Voice.

I forwarded my iPhone number to my local Google Voice number (it's in iPhone settings under phone). In Google Voice turn off forwarding to the iPhone [1] and all other numbers.

Now calls to my mobile to go my GV voice mail. All messages are transcribed, and an email is sent to my Gmail account with the transcription and a link to the audio (which plays, interestingly, in the iPhone's video player -- weird, but it works).

So when I travel voice messages will reach me whenever my iPhone has WiFi services, which is usually a few times a day. Not bad.

When I cross into the US I just turn on the iPhone and turn off forwarding.

Now to see what happens if I try to may a GV call from Canada (I think it won't let me do this, but I'll give it a try).

[1] If you forget to do this, you can set up an infinite loop. GV forwards to the phone which forwards to GV. Ok, so I forgot. Turns out the phone rings for a while but GV eventually goes to voice mail (because you're not picking up the forwarding). If you turn off forwarding to the phone GV picks up incoming calls immediately.

Update 8/26/2013: A more sophisticated version of this.

iPhone notifications – two services that create notifications for email

In the past week or so I’ve come across two different services that create iPhone notifications upon email receipt. One here:

macosxhints.com - Push any email to the iPhone via third-party app

There have been several hints in the past, including these two of mine, with regards to using push email on the iPhone, or using MobileMe with custom reply-to entries, etc. A new application called PushMail ($5; App Store link) seems to me to be the ideal way of using push email (or any mail) on the iPhone…

… Essentially, PushMail gives you your own new email address, something like a@dopushmail.com. Everything that gets sent to that address has a push notification displayed on your phone. The notification displays the sender, the subject, and as much of the email as can fit in a notification. So, you can configure your regular email addresses to all forward a copy of your email to that new address, and you will have your email pushed to you.

This is an option in the settings for most webmail email services such as Gmail, or you can configure procmail to forward a copy, if you've got control of your email server. ..

..You can to the same for free using text free lite - lookup in appstore textfree, they will give you a push enabled smth@textfree.us address, then just forward to that address…

and another:

TUAW: Apple approved Gmail app for iPhone. Has hell frozen over?

TechCrunch is reporting today that an iPhone App that utilizes the Apple Push Notification system to let you know you have new Gmail is about to hit the app store. The app, called GPush, is developed by Tiverias Apps, and gives Gmail users an instant notification that new mail has arrived. iPhone users will still have to read their mail, either in a browser or the Apple Mail client, but the notifications will be essentially instant.

GPush will be US$0.99 for a week, then will be sold for $1.99 after.

The Tiverias sight has more on GPush including an FAQ. It does work with Google Apps.

That means I could create an email account on one of our family Google Apps domains just for push email. Then I could use that whenever I have something I want to be notified of, like an email notification related to a Google Calendar event. Using an account like this has a very important advantage – the way GPush works their server has to hold your account un/pw:

Should I be concerned about providing my password to GPush?

When we created the app, we committed first and foremost to security. We are using multiple levels of encryption including SSL and obfuscation. We had a penetration testing team run their analysis on the server and passed their certification.

Briefly, HELL YES you should be concerned. My Gmail credentials are among the most valuable “things” I own. Steal my car please – at least that’s insured! (It’s also very crummy.) I’m not giving the keys to the empire to any vendor. A purpose build Google Apps account though – that I could do.

I’ll provide an update on how well this works.

We can now tweet from Google Reader

When you click the Twitter link Google Reader opens Twitter with a URL shortened link to the post ..

A flurry of features for feed readers

We've made it easier to share posts you like to Blogger, Twitter, Facebook, and more, with our new 'Send to' feature...

Just head over to the settings page, and enable the services you want to use.... you can create your own 'Send to' link with a URL template...

To share an item on one of your sites, simply click the 'Send to' button and choose your service. If you're into keyboard shortcuts, 'shift-t' will do the same.

It's a lesser version of what I wanted Byline to do. It's interesting, but, darn it, they got it wrong! I want a single button that would let me write a comment for sharing in Google Reader, and have that comment (length limited) go to Twitter. Also there's no option to send a post to multiple sites at the same time.

You can also send to Blogger, but it sends the entire page to the editor. I don't know if I'll find it very useful for blogging.

Overall, it's a step in the right direction, but only a smallish step.

Update 4/25/10: This is still not a part of the mobile reader UI. I think it's a dead end.

Verizon's WiFi service doesn't support OS X

This surprised me ...

Macintouch - Mac Marginalization:

... the rumor is that Verizon intends to support Mac users on its WiFi service in October, about 4 months after making the service available to Windows users. Such a delay could have been avoided by simply using platform agnostic user-verification methods....

Verizon chose to use some proprietary logon app?! That's such a peculiar choice it casts doubt on all of Verizon's technical judgment.

The persistent virtue of old machines

I'm typing this post on a G3 iBook running OS X 10.3 and Camino 1.6.8.

I've not used this laptop for a while, it sits in the kitchen and Emily owns that space. So I was surprised to discover that it works very well as a web client (though the battery life is rather minimal -- the LiON battery died years ago).

The secret, of course, is to know when to stop upgrading. Theoretically it could run 10.4, but I know that would be slower than heck (it came with OS 9 and, I think, 10.1 or 10.0). Camino is a beautiful browser and this version runs very well on 10.3 (even has Expose!) . The iBooks always had great radio reception, and the 802.11b Time Capsule connection works (though there were some oddities initially).

Google, of course, is doing the heavy lifting. They keep getting faster, so my iBook keeps getting faster. That's the Chrome OS promise.

It's not just the iBook. Upstairs, with some hardware fixes and a few workarounds, my ancient XP box keeps getting faster with each release of Chrome. (My G5, however, is kinda slow with 10.5. I should have stuck with 10.4. The MacTel transition shortened the G5 lifespan.)

Computing ain't what it used to be. Feels to me like we need one powerful machine to manage photo, video, backup and file services, and everything else can just coast ... (Wii for games.)

PS. Considering the build quality of many netbooks, an old laptop with a newish battery is pretty price and performance competitive.

Facebook Pages: Beware the traps

I recently created a Facebook "Page" for the Minnesota Inline Skate Club. It was easy to create it, but I ran into two well known flaws.

I’ll describe those, but first I need to distinguish a Profile from a Page. A Profile is the representation of a person and is typically bound, behind the scenes, to a phone number. So a Profile is a pretty strong identity claim. Every Facebook user has a Profile.

A Page is a public manifestation, it’s always associated with exactly one Profile. The Profile owns the Page. Pages typically belong to organizations, businesses, and public figures.

Pages are fairly easy to create, though like all things Facebook there’s no obvious documentation. There are, however, two significant flaws:

1. The Page Creator is the Page Owner. Ownership cannot be changed; Pages cannot be moved from one Profile to another. The Owner is always an admin. The Owner may appear in the list of Fans, but they cannot post as a Fan. Everyone else who ‘friends’ a Page is a Fan. The Owner may make Fans administrators.
2. Owners can appear in the Fan list, but they are not truly a Fan. An owner cannot post with their Personal Profile, they always post as the Page.

The Facebook Page Admin forums have hundreds (thousands) of posts complaining about these two issues. The pleas are not answered.

It appears that the “proper” way to create a Page at the moment is to

1. Create a new Profile that will own the page (Page_Profile). Do this using a transferrable email address. So this is a transferrable Profile.
2. Create the Page.
3. Logout and login with your personal Profile (Personal_Profile). Become a Fan of the Page.
4. Logout and login with your Page_Profile. Promote your Personal_Profile to admin.

Now, depending on how you login to Facebook (which Profile you wear) you can post to your Page either as a Fan or as the Page (ex. Minnesota Inline) itself.

This is obviously a rather awkward arrangement; I wonder if the creation of a Page_Profile is even legitimate with Facebook’s Terms of Service. Facebook really does need to fix this, but I’m sure the fixes are not trivial.
