Twitter Plans to Stop Counting Links and Photos in 140-Character Limit

iPhonehowapple 发表了文章 • 0 个评论 • 254 次浏览 • 2016-05-19 15:16 • 可能属于这些话题

Twitter has plans to stop counting photos and links within the 140-character limit allowed for each tweet, reports Bloomberg. Removing photos and links from tweets will allow tweets with media to contain more text. 

At the current time, photos take up 24 characters and links take up 23 characters, eliminating 47 available characters when both are included in a tweet. Twitter is reportedly introducing the change to give Twitter users "more flexibility" after exploring methods that would allow users to include more text in tweets. 

Twitter has made efforts to give users additional characters to work with in the past, implementing tweet quoting features, using link shorteners, and removing character limits from Direct Messages. 

Twitter has included a 140-character restriction since it launched in 2006, put in place to stay within the limits of the standard 160-character length of SMS messages with 20 characters left as space for a username. Reports in January suggested Twitter was considering eliminating the 140-character limit and allowing tweets to contain up to 10,000 characters as part of a project it called "Beyond 140," but Twitter CEO Jack Dorsey later said the character limit would not be changed. 

Twitter is expected to implement the change in the next two weeks.

Use “Delete Immediately” on Files to Bypass Trash in Mac OS X

iMachowapple 发表了文章 • 0 个评论 • 300 次浏览 • 2016-05-11 19:55 • 可能属于这些话题

The latest versions of OS X include a new ability to immediately delete a file or folder from the Mac, bypassing the Trash can. Essentially how the “Delete Immediately” feature works is by circumventing the Trash and rather than waiting for user action to remove the files, it just deletes the file(s) instantaneously from the Mac, making the delete immediately function faster than the typical manner of removing a file in OS X.

Delete Immediately is a handy feature if you want to rid a file or folder from the Mac right away and without having to manually empty the Trash, it effectively skips the Trash function and just deletes the files. This is not intended to be a replacement for secure empty Trash, however and doesn’t offer the same rewrite function.

There are two ways to access and use Delete Immediately in OS X, with a quick access keystroke and from the File menu. 

There is no way to undo this action so only use Delete Immediately if you really truly do want to vanquish a file from the Mac. 

Delete Files Immediately with a Keyboard Shortcut

The quickest way to access the Delete Immediately function in OS X is through a keyboard shortcut:

Select the file(s) or folder(s) you wish to instantly and permanently delete and hit the following keystroke sequence: Option + Command + Delete
Confirm with the dialog that you wish to delete the files permanently and immediately






[Confirm to delete a file immediately in Mac OS X]

This just circumvents placing the files into the Trash, it deletes the file(s) immediately from the Mac. 

Access Delete Immediately from the Finder

You can also access the Delete Immediately option and skip the Trash by using the File menu in the Mac file system:






[Delete immediately in Mac OS X Finder and bypass the Trash]

Select the file(s) or folder(s) you wish to instantly and permanently delete then hold the OPTION key as you access the “File” menu from the Finder
Choose “Delete Immediately” from the File menu
Confirm with the dialog that you wish to delete the files permanently and immediately






[Confirm to delete a file immediately in Mac OS X]

Again, this skips the Trash, and the files are instantly deleted. The same as using the keyboard shortcut.

Similar to using the Trash is that if a file is locked or in use the Trash action will be prevented, and if you encounter a “item can’t be moved” error, you’ll likely need to quit apps and relaunch the Finder first. 显示全部

Fixing an “Item can’t be moved to Trash because item can’t be deleted” Error in Mac OS X

iMachowapple 发表了文章 • 0 个评论 • 265 次浏览 • 2016-05-11 19:53 • 可能属于这些话题

Deleting files and folders from the Mac is usually as simple as dragging the item to remove into the Trash can, but on rare occasions things don’t quite go as planned. One of the more peculiar errors when trying to remove a file appears in the form of the following message when attempting to send something to the Trash; “The item “filename.ext” can’t be moved to the Trash because it can’t be deleted.”


That error message is not exactly descriptive or helpful, but, as it appears to be a bug related to the Finder, the issue is usually fairly easy to resolve by quitting and restarting the Finder. 

There are several ways to accomplish that, the easiest perhaps being the familiar Force Quit shortcut:

Hit Command+Shift+Escape to bring up the Force Quit menu, select Finder and choose “Relaunch”

Option and Right+Clicking the Finder icon in the Dock gives the same option:

[Relaunching Finder]

If you’re a command line user, you can also choose the killall command in the Terminal app.

Whichever approach you go with, be sure to let the Finder completely load again. Then, once the Finder has opened again, you should now be able to remove the file as intended by sending it to the Trash either with a Command+Delete or by dragging and dropping it into the OS X Dock Trash icon. This is fairly basic troubleshooting, but it does work, and has apparently worked to resolve the error for quite some time judging by user responses on Apple forums

Note that if the file in question is locked, you may encounter yet another error now that’s in the Trash can when you go to actually delete the file. If so, that’s also easy to resolve by forcing the Trash to empty whether contents are locked or not. 

In some cases, the inability to trash a file like this is probably a Finder bug, though since it is easy to trigger the message with partially transferred files, it could also be a protective mechanism against prematurely removing files that are partially transferred either through local file sharing or downloading from the internet. Keep that situation in mind if you’re encountering the error message in when trying to trash something from Finder, as it may be resolved by stopping the active file transfer taking place too. 显示全部

How to Access Files in iPhoto?

NoteBookshowapple 发表了文章 • 0 个评论 • 287 次浏览 • 2016-05-09 01:05 • 可能属于这些话题

If you're new to iPhoto it can be a litle confusing. You may be used to organising files in folders on your Hard Drive. This is a perfectly good way to organise files but pretty hopeless for organising Photos.

 

Remember that file is just a container -  a box - for your Photograph. Think of it this way:  In my iTunes Library I have a file called 'Let_it_Be_The_Beatles.mp3'. So what is that, exactly? It's not the song. The Beatles never wrote an mp3. They wrote a tune and lyrics. They recorded it and a copy of that recording is stored in the mp3 file. So the file is just a container for the recording. That container is designed in a specific way attuned to the characteristics and requirements of the data. Hence, mp3.

 

Similarly, that Jpeg is not your photo, it's a container designed to hold that kind of data. iPhoto is all about the data and not about the container. So, regardless of where you choose to store the file, iPhoto will manage the photo, edit the photo, add metadata to the Photo but never touch the file. If you choose to export - unless you specifically choose to export the original - iPhoto will export the Photo into a new container - a new file containing the photo.

There are times when you need to get to a photo ouside of iPhoto - to upload, to share, to add to a document for instance.

There are many, many ways to access your files in iPhoto:   You can use any Open / Attach / Browse dialogue. On the left there's a Media heading, your pics can be accessed there. Command-Click for selecting multiple pics.
\
It looks a little different in 10.10 Yosemite:

(Note the above illustration is not a Finder Window. It's the dialogue you get when you go File -> Open)
You can access the Library from the New Message Window in Mail:

How do I access my Photos in Aperture?

NoteBookshowapple 发表了文章 • 0 个评论 • 280 次浏览 • 2016-05-09 01:03 • 可能属于这些话题

How do I access my Photos in Aperture?
If you're new to Aperture it can be a little confusing. You may be used to organising files in folders on your Hard Drive. This is a perfectly good way to organise files but limited for organising Photos.

 

Remember that file is just a container -  a box - for your Photograph. Think of it this way:  In my iTunes Library I have a file called 'Let_it_Be_The_Beatles.mp3'. So what is that, exactly? It's not the song. The Beatles never wrote an mp3. They wrote a tune and lyrics. They recorded it and a copy of that recording is stored in the mp3 file. So the file is just a container for the recording. That container is designed in a specific way attuned to the characteristics and requirements of the data. Hence, mp3.

 

Similarly, that Jpeg or Raw is not your photo, it's a container designed to hold that kind of data. Aperture is all about the data and not about the container. What does that mean? Essentially, it means that (regardless of where you choose to store the master file) Aperture will manage the photo, edit the photo, add metadata to the Photo but never touch that file.  If you choose to export - unless you specifically choose to export the original - Aperture will export the Photo into a new container - a new file containing the photo.

 

There are times when you need to get to a photo outside of Aperture - to upload, to share, to add to a document for instance.

 

There are many, many ways to access your photos that are managed by Aperture. Which to use depends on the purpose you have for the image. In general there are two main ways: Media Browsers and Exporting.

 

Media Browsers

 

Media Browsers are all through the OS. They're in every Open... Attach... or Browse... dialogue, they're built into the tool bars of apps like Pages, iMovie, Final Cut X, Word, Mail and so on. Media Browsers access your Aperture Preview.

 

 

Note: That is not a Finder window. It's the dialogue you get when you go File -> Open... in an app...

 

 

Here's the Media Browser from mail

 

 

 

Note that the entire Library is available, note too the search box at the bottom which can be use to search on any text - titles, keywords etc -

 

The Media Browser yields your Aperture Previews. The quality of these can vary depending on the settings you choose in the Aperture Preferences. You must also elect to share the Previews with the iLife apps for the Media Browser to work.

 

There are limitations. There is no way to access a Raw file via Media Browsers, they are always jpeg, they have limited support for Exif and IPTC and so on.

 

Common uses for the Media Browser: when you need to use a shot in a word processing document, in a movie or for a handy email of a shot to family or friends.

 

Note: Drag and drop (or Copy and Paste) from the Aperture Window also gets the Aperture Previews.


 

Exporting

 

 

There is a whole chapter in the manual on Exporting so I'm not going to recap that here. But there are some headlines to note, and common causes of confusion.

 

 

You can access the Export options by selecting a shot or shots and going File -> Export

 

 

You can export the Original file - that's the Raw if you're shooting Raw, or the unedited Jpeg. Basically, this is how you get out exactly what you put into Aperture.

 

 

You can export versions. These are your processed or edited shots. Have a look at the shot below

 

 

There are a lot of options. You can export to Jpeg, Tiff, PNG or PSD, in a variety of sizes and qualities, including metadata or not as you prefer. You can use the existing export presets or, at the bottom of the list you'll see the Edit... option. This allows you to create your own preset. So, if you regularly export to low quality Jpeg at 75% of the size, you can create and name a preset, and save it.

 

For instance, in the shot above you'll see the chosen preset happens to be JPEG-Rett Site - which is a created preset for a specific purpose.

 

 

Some common confusions:

 

Size refers to dimensions - length by breadth. So, a Jpeg at Original size will not have the same file size (or 'weight') in MB or KB as the original. It will be the same dimensions are the original, measured in pixels.

 

 

The File Size (or 'weight') in MB or KB is determined by the Image Quality - and that's an option you set in when you choose (or create) the export preset.

How to deal with the "Activation Server Unavailable" error message when restoring an iOS device
