MacRumors iPhone Blog: Apple Forces Removal of ‘Free Memory’ Functionality From iPhone Applications

While third parties are limited from developing background applications for the iPhone, Apple allows their applications such as the iPod, Safari, and Mail applications to continue to run. After prolonged use, these background applications may take up most of the memory (RAM) on the iPhone that can create interface sluggishness and prevent some memory-intensive applications from loading.

users wishing to avoid a complete device restart force quit Mail, Safari, and iPod if necessary by holding down the sleep-wake button until the red slider appears and then holding the home button until the application quits.

High end compact cameras

Right now I carry a monstrous 5d ii with 3-4 lenses (24-105, 16-34, 100-400, 50 f1.4 for available light). But there is a big gap between a 3mp iPhone and 25 pounds of 21mp gear. What’s in between is finally getting filled in with micro 4/3 and high end compacts. The ideal is a point and shoot with optical viewfinder, true iso 400-800 with low noise and great fast optics with decent zoom say 24-105 equivalent. Interchangeable lenses are nice too.

We aren’t completely there yet but getting close. Here are some choices.

1. Panasonic Lumix lx3. $500. Is current leader. Sensor is about 0.5 inches so decent. Really fast lense. Sort of compact. Main issues are lack of viewfinder and sensor is still small.

2. Olympus digital ep-1. $800 Use micro 4/3. Like a small rangefinder. Sensor is relatively huge at 2x factor vs. 1.6x for aps-sized digital rebel. Almost a buy except it has no optical viewfinder.

3. Canon s90. This is a lx3 killer. 10mp which is actually unintuitively better because u want bigger pixels for less noisy performance. No reviews yet.

4. Panasonic micro 4/3. Even better but $1500 so hard to justify

Converting from exchange to google gcal and contacts

Given exchange isn’t reliable on calendar how can I use can iPhone, blackberry, iCal on mac, outlook on pc against googles backend mail, contacts and calendar.

First off since last year google has done all the work to allow exchange replacement. It is a mess to figure out and I’m sure there r many bugs. Bemut here is how to convert.

1. For calendar, sync entourage to iCal with entourage selecting sync preferences.
2. Export iCal calendar. It us an ics file
3. Import into google calendar.

For contacts.

1. Sync entourage to nac addressbook via preferences/sync/to address book

2. In addressbook choose o
Preferences google and this eventually sinks all.

Now both contact and calendar is in.

1. If u have iCal then set it up to in preferences/ caldav/ so u can see gcal.

2 do same for iPhone by picking right activesync server.

Cloud 9

WikiAnswers – What is the meaning of the idiom ‘on cloud 9’

According to the “Morris Dictionary of Word and Phrase Origins,” the phrase is based on U.S. Weather Service terminology. This theory holds that cloud types are numbered, and that “cloud nine” is the designation given to “cumulonimbus” clouds, the highest-flying clouds around, making them an apt metaphor for being “on top of the world.”

When “you’re on cloud nine” you feel wonderful!

Where does the phrase “on cloud nine” come from?

The phrase to be on cloud nine, meaning that one was blissfully happy, started life in the United States and has been widely known there since the 1950s; it’s since spread worldwide. It’s said to have been popularised by the Johnny Dollar radio show of that period, in which every time the hero was knocked unconscious he was transported to Cloud Nine. But that wasn’t the origin of the phrase. It’s been around since the 1930s, though early examples show a lot of numerical variability, with the cloud sometimes being as low as number seven or eight or as high as thirty-nine, though seven and nine were most common.

These discrepancies make me suspect the usual explanation of its origin, which is that it comes from the US Weather Bureau. The story is that this organisation describes (or once described) clouds by an arithmetic sequence. Level Nine was the very highest cumulonimbus, which can reach 30,000 or 40,000 feet and appear as glorious white mountains in the sky. So if you were on cloud nine you were at the very peak of existence.

The term has always had close associations with the euphoria that is induced by certain chemicals — alcohol in its earlier days but more recently crack cocaine — so perhaps we shouldn’t ask for too great a level of exactness in counting. And the cloud here is an obvious reference to some drug-induced dreamy floating sensation. But I suspect, without having anything so restricting as evidence, that seven was chosen because it’s a traditional lucky number and that today’s more usual nine appears for similar reasons — for example it also turns up in dressed to the nines and the whole nine yards.

Then, according to Thomas Veil on the Phrase Finder website:

The true and original origin of “Cloud 9” is derived from Buddhism.

The state of being in “Cloud 9” is the penultimate goal of the Bhodisattva.

Check on Martin Luther King’s paper on
“The Chief Characteristics and Doctrines of Mahayana Buddhism”.

“The Mahavastu, a late Hinayana work, gives a list of ten stages in the progress of the Bodhisattva, and the same number is retained, with modifications in detail, by the Mahayana authorities… In the ninth stage the seeker reaches the point when all his acts are unselfish, done without desire. Finally the Bodhisattva reaches the tenth stage in which he becomes a tathagata, a cloud of dharma.[Footnote: Radhakrishnan, op. cit., pp. 601, 602.]

I believe that the ninth cloud is also referred to as “The Bright Cloud of Great Refuge”.

Finally, we have Christi the Wordsmith, who weighs in with:

In Dante’s Paradise, the 9th level of heaven is closest to the Divine Presence, which itself dwells at the 10th and highest heaven. This notion may have enhanced the popularity of the expression on cloud nine.

So it seems that there is no single answer. Which, in my opinion, makes your question particularly fascinating.

Miscellaneous Postings

From the last trip to Ho Chi Minh City, always like to collect a list of conveniences and places to get things. It’s amazing what a few queries can produce.

Anyway first some random facts on connections from Seattle. Best flight in terms of time is for an afternoon flight BTW if you are concerned about what are the more comfortable seats, Seatexperts.com is an amazing site. Tells you what the best seats are etc.

NWA. Leaves 1415 SEA via NRT and arrives 2310 SGN. Seats on first leg at 150 degrees on a A330. Main issue is that the seat power doesn’t work on either leg, so you are warned.

KE 20/681. Leaves 1440 SEA via ICN and arrives 2220 SGN which is faster. The seats are flat but incline 150 degrees in business class and they do have a first class. Haven’t tried it yet and more expensive than Northwest. But they don’t fly everyday. They skip Weds and Sunday. 777-200 on SEA ICN leg and then a -300 on ICN SGN leg. Some of the -200 have Kosmo Sleepers which are true lay flat seats.

If you have to work the whole day, there are some interesting choices:

Eva Air 25. Leave 0210 SEA and arrives 1130 SGN via TPE which is as efficient as NWA flight, but really good if you have work to do in Seattle and give you half a day in SGN. In business class on their A777-300, they are 2-2-2, slanted lay-flat seats and you want the center aisle so people aren’t climbing over you. They have 120VAC too and a panasonic AVOD.

And if you are stuck on United, the connections are works, but at least the flights have lay-flat seats. You can check on Suite Dreams. This site shows all the upgraded planes. Right now all the 767s and most of the 747s. But the routes include SFO-SYD and SFO-HKG. So you can take SEA-SFO-HKG-SGN, this takes a long time 9AM-10PM, but at least you get there on UA 869

For instance there is normally an online expat community like alloexpat.com

Places to eat, drink and be merry

Veggies. Best place to buy produce
Cafe Mojo. Good cool coffee next to the Sheraton
Xu. Good ex-pat drink bar.
Anham Gourmet Market. All those treats from home
Vino’s. Wine, yes its 2x the price, but you can get it
The Temple Club. Near Sunwa Tower, Hey Branjolina can’t be wrong when the eat
Cepace. Wine and drinks for the late night next to Lancaster
Q Bar. In the Opera house

Calling overseas

Time once again for the annual review of calling overseas. Let’s pick a random example country and see how low the rates can go. For instance, if you want to call a Vietnam cell phone, what are the costs

From US to Vietnam Cellular

If have a mobile phone and sign up for AT&T World Connect, the cost is $0.50/minute. Much lower than the $3/minute if you don’t have a plan and you pay $5.00/month for the service, so it’s a good first cut.

If you have Skype and you call to another computer, then it’s free. If you call to a Vietnam mobile then it is $0.32/minute.

If get a phonecardsreview.com and looks at the reviews then a good service to use from your cell phone is one that uses local access number and then dials to Vietnam, Nobelcom.com comes out pretty well there is a really complex array call to Vietnam Landline and Vietnam Cellular cards that are hard to figure out. They mainly differ on rounding and the weekly connection fee. So for instance the apparent cheapest called Hello Vietnam Cellular is 5.4 cents per minute, but it rounds to the nearest 5 minutes (so at least $0.25) and has a $4/month fee.

On the other hand, there is 9.0 cent card that rounds to the nearest second and has no monthly fee. The cross over point is how many minutes you are calling. If you call more than 114 minutes/month every month then the Hello Vietnam. That is because 9.0-5.4 is the difference of  cents against the $4 monthly fee ($4/(0.09-0.054)=111 minutes). So it depends on your call volume. The nice thing about prepaid is that if you don’t use it, you aren’t having to cancel. The deal here is if you buy $40 and have auto-recharge on, then the first card is actually $35 which will give you 470 minutes. Then you can see how your use goes. The payback against Skype is that is 4x cheaper!

As another example the $0.075/minute card has a $0.49/month so this pays back compared with the $0.090 card or 0.49/(0.090-0.075)=32 minutes/month minimum usage. So that makes the 7.5cent card the best buy if you are calling reasonably regularly every month.

Finally, the $0.064/minute card is a $2.80/month, so pays off at 133 minutes.

Calling from Vietnam wired phone to and from the US

This is more complicated. You can use Vonage which gives a local number and then people can dial to you. But it is $20/month. Your phone gets a US phone number, so anyone from the US can call it for cheap and you call using VOIP to anywhere in the US for a low cents per minute.

If you want to save the $20/month, you can use Skype from your computer, but that isn’t super convenient. So, you really need a handset to do this. While there are Wifi handsets that do this, most folks haven’t like the battery life or another features of the Belkin or the Linksys that does this.

The best solution is a DECT phone which is lower power and generally better. Google Shop has reviews of the Linksys iPhone CIT 400 that are general good and not super expensive at $130. It works with Skype.

For Skype, you need Belkin Wifi phone and then you need Skype In, so that there is a US phone and then this routes to the Wifi

Calling from Vietnam to US

Well, Vonage at $20/month has been the traditional way, but if you want to use Skype which is way cheaper. The main issue is that if you don’t want a computer on all the time, then you really want the Skype firmware built in and then have an IP connection. There are three flavors. A traditional corded phone, a Wifi wireless phone, a DECT wireless phone.

The corded phone is cheapest and most likely to work well. The Belkin F1PP010EN-SK Desktop Internet Phone for Skype has the best reviews on Amazon for any Skype phone. So seems like a good safe choice. You can dial out over Skype, but more importantly, you can buy Skype In and have a US phone number attached to it, so you can call from the US into any overseas country.

And surprisingly for a Wifi phone, the no-name brand Ipevo S0-20 Wi-Fi Phone for Skype seems much better than the Belkin Wi-Fi Phone for Skype F1PP000GN-SK, Netgear SPH200W or even the discontinued Linksys CIT400.

iPhone Speakers

There are so many units out there and iLounge doesn’t spend much time reviewing these days as the market has stabilized, so what are the best systems out there for sound:

  1. Boston Acoutics Horizon Duo-i as a clock radio Logitech lead for a while with the discontinued Anywhere High-Performance (A) which beat the Bose Soundeck (B+), but disappointed with the Anywhere Dream (B). So Boston Acountics (A-) has the new mantle at $200. I’ve used the iHome iP99 clock radio and they sound just Ok and it isn’t iPhone compatible. 
  2. Boston Acoustics i-DS3 Plus (B+) is a 2.1 sound system that is like a mini-stereo for your iPhone/iPod, so more appropriate if you want great sound quality. It can also be used with a TV as a 2.1 stereo system because is has RCA jacks. $386 from Amazon
  3. Logitech Pure-Fi Anywhere 2 (A-). Probablyt best compromise in portable “boom box” speakers for the Iphone/iPod.
