Replacing iDisk with online storage of your own
With the June 30, 2012 death of Apple's MobileMe service looming just a little over two months away, some Mac users are still wondering what to do to replace one of the keystone pieces of the service -- iDisk. Macworld's Glenn Fleishman provided some tips today on how to replace iDisk with your own online storage using some common Mac apps that let you treat a remote FTP, SFTP, WebDAV, or Amazon S3 server like a Mac volume. The trick, says Fleishman, is to get file-sharing access via a hosting company or a storage system like Amazon S3, Google Storage, or Rackspace Cloud Files, and then use either Nolobe Software's Interarchy (US$30) or Panic's Transmit ($34) to create a Mac-mountable volume. Of the two Mac apps, Fleishman notes that Transmit works most like the default mode of iDisk. It provides a glimpse into the remote server's file structure, but doesn't download or sync files locally. As such, if you need to open a large remote file to edit it on the Mac, you must first wait for the file to be downloaded. After an edit is made, saving the file requires the file to be uploaded back to the source. That can definitely take some time. Interarchy's Net Disk feature is more like iDisk with synchronization enabled, allowing a Net Disk to synchronize changes to your computer, from your computer to the server, or in both directions. This ends up working more like Dropbox, where files are stored locally instantaneously, but then synchronize with the server behind the scenes. Fleishman includes instructions on how to create a mountable disk using either Transmit or Interarchy. Just remember to get your iDisk replacement into place prior to June 30th!
iPhone 4 has 802.11n, but not the "awesome" 802.11n
I suspect many people were very happy to see that the iPhone 4 was listed as having 802.11n. I know that I was. I have a dual-band network at home which separates 802.11n from 802.11b/g, and that's made a huge difference in transfer times. But there's also another benefit of 802.11n: it can use the 5GHz frequency band instead of the 2.4Ghz. Without going into too much detail, most (but certainly not all) of the benefit of 802.11n comes if you use 5Ghz, because it isn't cluttered with other devices like 2.4Ghz is. So imagine my dismay when I went to the iPhone 4 technical specifications page and saw "802.11b/g/n Wi-Fi (802.11n 2.4GHz only)" listed there. I wanted to double check my suspicion that this was bad news for people who want to avoid the interference issues that come with 802.11b/g. When you have a question about Wi-Fi, especially in the Mac world, the guy to ask is TidBITS & Seattle Times columnist Glenn Fleishman. If you've ever read a great, informed (and informative) article on Wi-Fi that even a mere mortal could understand, chances are pretty good that Glenn wrote it. He wrote the most thorough analysis of the Wi-Fi woes at the iPhone 4 demo that I have seen anywhere. I asked Glenn about this on Twitter, and he confirmed my fears that 802.11n in 2.4Ghz will suffer from the same interference that b/g devices do. This makes "802.11n" partly just a marketing bullet point for iPhone 4 instead of a truly beneficial feature. If you're currently running a 5GHz-only N network, your iPhone won't take advantage. For 2.4GHz N networks, you will probably get some speed boost over G (Glenn estimated perhaps 1.5x when using an 802.11n base station). When copying a 940MB file over my home Wi-Fi network between a Mac desktop and laptop, 802.11n took 2 minutes, 14 seconds compared to 15 minutes 45 seconds on 802.11g. Then again, most people won't be doing large wireless file copies to/from their iPhones until/unless wireless synchronization comes along. So yes, Apple can boast that the iPhone 4 has 802.11n and they're telling the truth, but don't expect much practical difference day-to-day. Glenn suspects that given the newer chip and more efficient use of the radio spectrum, we might get better battery life on N than on G -- but we won't know for sure until the iPhones arrive.
Take Control of Back to My Mac / Screen Sharing in Leopard
Glenn Fleishman of Macworld, Wi-Fi Networking News and TidBITS fame has written two new Leopard ebooks, both published today by Take Control Books. The new titles, Take Control of Back to My Mac and Take Control of Screen Sharing in Leopard, are part of the popular Take Control ebook series. Take Control of Back to My Mac provides many tips on how to get .Mac's MobileMe's problematic remote access service up and working for you, while Take Control of Screen Sharing in Leopard discusses the many tools available for sharing your Mac screen with others. The books are $10 each, but if you purchase both ebooks and enter CPN006780611BUN as a coupon code, you'll get an immediate $5 discount. There's no excuse to suffer in silence with Back to My Mac anymore!In the interest of disclosure, I've written two titles for Take Control Books, neither of which are discussed in this post.[Via TidBITS]
802.11n getting prelim certification in March 2007
Starting in March 2007 the Wi-Fi Alliance will start certifying next-gen WiFi products, which puts us at ease a little bit. As CNET reports, the ultimate goal is, of course, to make sure that all the prelim 802.11n stuff out there plays nice with each other, which currently can mess up existing legit WiFi networks. For those of you who haven't been keeping score at home, 802.11n has been fraught with total confusion since the beginning. Back in May 2006, the IEEE rejected the first 802.11n draft by a wide margin, failing to garner a simple majority, let alone the required 75 percent supermajority. Later that month, Glenn Fleishman at Wi-Fi Net News told us that Task Group N received around 12,000 comments on the proposed draft -- compared to the 2,000-some that most drafts generate -- which is another very bad sign. Unfortunately though, it still looks like the real deal officially official final ratification won't be done until 2008. The short version? Just to be safe, stick with your current WiFi setup until there's a new man in the White House, ok? [Via Wi-Fi Net News]
IEEE source: draft 802.11n timeline slipping yet again
More bad news for MIMO fans (if there is such a thing): Glenn Fleishman over at Wi-Fi Net News is reporting that an IEEE member has informed him of a delay in the timetable for expected approval of the final draft of the 802.11n Wi-Fi standard, from sometime this summer to late fall or even early winter. Fleishman's source claims that Task Group N received around 12,000 comments on the proposed draft -- compared to the 2,000-some that most drafts generate -- which is yet another bad sign following the group's earlier failure to garner even a simple majority in favor of the current proposal, much less the 75% supermajority needed for passage. With draft approval seemingly several months off at the least, it could be a year or even a year and a half before a final 802.11n standard is ratified, meaning that those folks who are already snatching up pre-N gear will have to wait even longer to find out if their hardware ends up being compatible.[Via Ars Technica]
