• Apple UDIF read only compressed (bzip2) in my iMac!

  I noticed a new feature added to my iMac:

  'Apple UDIF read-only compressed (Bzip2)'

  What? Why? and how did get there?

  Why do I need?

  I think, but not sure it was added after the last updated iTunes (version 12.1)

  No explanation will be appreciated.

  PS

  It does not appear in my Finder...

  Thank you

  

  

  

  This is the disk image to the Flash Player installer that you downloaded.

  It is not mounted, so it will not be displayed in the Finder.

  With it, selected as shown in the second screenshot, click on the button of the mount. Then, eject in the Finder.

• do I really want to compress all my data?

  Hello

  I'm a peasant total techno and was trying to find out how much space was left on my macbook pro 2009.  In the finder, I saw "compress data" and thought that I remembered how to seller by recommending day to do so.  I clicked it, and my computer is making its way through 183,59 GB of data compression, which according to her, will take 5 days!  When I tried a google search, I came across a lot of complicated things that sounds like you should be only compress one file at a time.

  While we are there, please can you me how do I know how much space is left on my computer?

  Thanks a lot and it's okay if you roll your eyes.

  Hi Dana,

  You compress your entire hard drive? Or only some data on the hard drive folders?

  Compression of data such as pictures, documents, pdf files, and other similar files is perfectly OK!

  A file is made up of a bunch of metadata. Metadata is simply data about data. Well, there is some metadata is just useless in a file and there is no advantage. With compression, the file gets processed and been ejected from some of its attributes and metadata which translates to a much smaller file size.

  However, there are some data that you don't want to compress. It comes to binary files that build the operating system (OS). If you plan to compress these file types, then corruption is likely to occur or may occur. When data compression, make sure that you can do without affecting your operating system files.

  The reason why your compression takes so long is that you MOST likely have a disk speed is very low. Depending on your model laptop and the year, you most likely have a tough guy who has a speed of 5400 revolutions per Minute (RPM). This is... the magnetic disks inside the hard drive that revolve around a single PIN for read and write data. Low RPM train speed slow drive, which slows EVERYTHING down. * And to emphasize, if your drive is old and has a lot of reads/writes that took place during his life, so the speed of the discs degrade. This is what we call performance degradation.

  In your scenario, I guess you have a slow drive, low RAM and a processor low range. Given these factors, it would take time to process and compress all data on your drive.

  I suggest you kill the compression operation. Compression is really intended to those who is EXTREMELY low on disk space and they have no choice OR you have pure RAW data which can slow down operations in an application, you are working with, in which case compress you the data to remove some of that unnecessary metadata.

  In the future, when you get a new machine, it is preferable to an installation on your disk compression before starting to use your machine. The data will be then get compressed by increments, rather than in a single session, which takes a lot of time.

  I hope this helps.

  Thank you

• Compressing files for the WinSxS folder

  I wonder why the folder winsxs in Vista and Windows 7 do not use file compression? Due to the nature of the case, it would not affect the performance of the system and would save several gigabytes of disk space.  The only files that can be skipped is the manifest files that are less than 4 KB of size...

  The INF file is very small, I think it wise to use compression for a file on this folder as well :)

  Each regular on NTFS file can be considered be a single 'hardlink' a data element. You can have multiple hard links, which is like having the same file in two places with just the cost of the extra link and not the data. The '. 'and'.. ' directory? A few hard links in the current directory and the directory's parent. WinSxS is full of files that are installed as components, usually of Windows and other Microsoft software. When these recommended "settled" in a given place, what actually happens is that a new link (hard link) is created in the data file. It is one of the reasons why Vista can be installed that on NTFS - it made prolific use of hard links. The physical files has obvious implications - you're not only compressing the installation media, but only copies of the actual files that make up Windows. If you package, part of what you package consists of installed files - or files that you can install later. And Windows (or other applications) do not always provide a compressed file. For example, Vista will choke if you try to install the libraries shared IIS and its XML schema for winsxs files are compressed. They probably check that it still has the read-only attribute and I forgot to allow the presence of other attributes. Personally, I think it's a bug, but whatever it is, there is a risk that you must be aware of. No need to cherish luxuries (cause everythine come and go) even the life you have is borrowed (Cause you are not promised tomorrow)

  ===========================================
  DavidMCandy is correct... the data is missing.

  Looks like you were using Microsoft Office Picture Manager...

  When you go to edit pictures and choose to compress the images.
  E-mail messages... it reduces the dimensions of the picture in pixels
  to fit in a window of 160 x 160 (it's barely a size of thumbnails)

  Then, when you close the Manager of photo... it displays a dialog box
  who says:

  There are changes that have not been registered
  Save not save cancel

  If you choose... Save... pictures will be compressed and photo
  Farm Manager.  This action overrides (replaces) the original
  (uncompressed) versions of the photos and the recovery is not a
  option.

  To prevent this from happening in the future... create renamed
  copies of the photos 'before' compression and only compresses
  copies of famous.

• change the rate of compression of files zipped / achieve smaller files

  I'm trying to compress files for easier downloading, but the zip file is only compress the file by about 1 MB, is it possible to compress the file more?

  N ° in general all utilities file compression give the same result, the compression ratio you get depends on compressible how files are. Photos and videos are often as tablet as they can get, and because programs are made mainly of random data which don't compress well, they compress much further.

• compress the question from the table

  My question is simple:
  
  If I execute this SQL:
  

  ALTER TABLE some_table_name MOVE COMPRESS;

  and the table is already compressed, Oracle jump or spend time re - compress?
  
  Why I ask this is because I have a few nice PL/SQL that loops through all the tables
  in my schema, I have about 1800 tables and it compresses, but it takes a long time, hours
  and I would like to only compress Tables which are not already compressed, so compressed, jump, so
  that's why I ask... try to determine whether or not PL/SQL needs a dry:-)

  To continue the question I found the following:

  (a) have compression enabled for a table does not necessarily mean that the data is compressed. If compression is enabled with the statement:

  ALTER TABLE tablename COMPRESS;
  

  the existing data in the table remain uncompressed.

  However the execution of the order

  ALTER TABLE tablename MOVE COMPRESS;
  

  Compress in the existing data in the table and it is caught in time.

  Try to compress an already compressed or partially compressed table is taken on time. Oracle will analyze the data in the table again and try to compress.
  I did a test on a table with half million records already compressed and time was almost the same as the initial compression.

  You can do a quick test on your environment to verify that.

  Sorry for the misinformation, I provided before.

• Need information/advice on dataware House on 11g compression

  We have an initiative to compress our constantly growing data warehouse.
  
  Is level operating system AIX, db version 11 GR 1 material, will go to 11 GR 2.
  
  We would like to know where I can get a link about what is best to apply a reclassification compression in data warehouse db.
  
  I tried the oracle documentation and don't know where to look.
  
  and more compression is a licensed product? No performance issues? and practical advice are appreciated here.

  Compression of the table requires no any key that is the only compression is made through direct additional licenses insert good enough for a data warehouse. Obtain and maintain a compression for regular and up-to-date inserts to a license for Advanced Compression.

  Performance for inserts using the direct method does not seem to impact to load performance, but updates and regular inserts take somewhat of a sudden when you use compression. Queries that have all significant IO operations seem to benefit the most compression and more the number of I/o operations more than the impact on performance tends to be. Remember that compression takes a CPU hit for compression and compression operations, while this doesn't seem to be really big, that this is a consideration if your system already has problems of CPU resources.

  I found that partitioning and compression used together provides the best performance when using the partition key and partitioning offers benefits for facilities management, scope/level partitioning offers the benefits of a data warehouse management.

  A few references in addition to the documentation which is a decent place to start research on google about Oracle Advanced Compression also returns tons of results:

• Compression PNG in Photoshop

  In saving an image in Photoshop as a PNG, the only compression options are small/slow and fast/none. Is it possible to manually set the compression level to somewhere between these two options?

  Hi Lindsay!

  If you use the backup to the Web feature rather that record under, select PNG - 8, which gives you more control over the export parameters.  See the image below.

  However, if your concern is the size of the file, you might be better to save it in JPEG format, rather than lower the quality of a PNG image as JPEG files recorded using high quality will often smaller than a comparable PNG with no noticeable quality reduction.

  I hope this helps!

  I think that the problem is a network file or because I put the wrong password and I cannot detect this error. as I said the VPN working properly with another MAC using the same network.

  Help...

  You shouldn't be messing with the security features of the operating system.

  Problems may have to do with the network, or client software that you use.

  I start by making sure all the software are updated and then create a new entry, vpn, double control system that everything has been entered correctly.

  FWIW, I use the built-in features of VPN on El Capitan to connect to my University regularly and without problem.

  I'm not familiar with "Fortinet", and I suspect that you may need to be updated, or simply use the built-in VPN.

• The Windows fax service cannot start because there is no such thing as a privilege in the fax service account.

  I'm trying to set up Windows Fax and Scan to store faxes "received" in a folder encrypted (EFS). (I use Windows Vista Business).

  The fax service will not start if it set to log on as a "local system account", but faxes are stored with the certificate of local system and inaccessible to other users.

  To work around this problem, I tried to configure the Fax Service to log on under a specific user account. However, after that and try to re - start the Service I get.

  Error: 1297 as a service privilege is needed to function properly does not exist in the service account configuration.

  One of the services that begins with the "local system account" does not automatically start with a normal user account and if you get the message.  Most of the services are designed to start with the local system account and not a special user account (actually, not on my system using a specific user account for services).  I think that part is OK and you must return it to the local system account (so eliminate the error message and remove that as a problem to solve).

  I think the question may also be a permissions problem in the user access to the fax.

  To view your permissions, right-click on the file/folder, click Properties, and check the Security tab.  Check the permissions you have by clicking on your user name (or group of users).  Here are the types of permissions, you may have: http://windows.microsoft.com/en-US/windows-vista/What-are-permissions.  You must be an administrator or owner to change the permissions (and sometimes, being an administrator or even an owner is not sufficient - there are ways to block access (even if a smart administrator knows these ways and can move them - but usually should not because they did not have access, usually for a very good reason).)  Here's how to change the permissions of folder under Vista: http://www.online-tech-tips.com/windows-vista/set-file-folder-permissions-vista/.  To add take and the issuance of right of permissions and ownership in the right click menu (which will make it faster to get once it is configured), see the following article: http://www.mydigitallife.info/2009/05/21/take-and-grant-full-control-permissions-and-ownership-in-windows-7-or-vista-right-click-menu/.

  To resolve this problem with folders, appropriating the files or the drive (as an administrator) and give you all the rights.  Right-click on the folder/drive, click Properties, click the Security tab and click on advanced and then click the owner tab.  Click on edit, and then click the name of the person you want to give to the property (you may need to add if it is not there--or maybe yourself). If you want that it applies to subfolders and files in this folder/drive, then check the box to replace the owner of subcontainers and objects, and click OK.  Back and now there is a new owner for files and folders/player who can change the required permissions.  You can change now switched to read-only (even if the main folder indicates that they are always read-only - you can access yourself as the owner).  You can keep them in read-only to other users, customers and administrators even (although they can support themselves and access, if they wish, and it is really not that you can do to stop it except protect the file with a password by using a 3rd party product.)  Here is more information on the ownership of a file or a folder: http://www.vistax64.com/tutorials/67717-take-ownership-file.html.  To add take ownership in the menu of the right click (which will make it faster to get once it is configured), see the following article: http://www.howtogeek.com/howto/windows-vista/add-take-ownership-to-explorer-right-click-menu-in-vista/.

  If that is indeed a problem of certificates (and it seems there is a but looks like he takes care of himself with the Wizard), then we must make the certificate available to all users of the system (from where it is now stored) - and I think I saw how to do this in secpol.msc.  Here is some information I found on EFS secpol.msc in the public key policies (you can get it by entering this in the area of research and the antering and then a double click on the program icon that appears) where you would put in place.

  --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

  The Encrypting File System (EFS) is an encryption technology of base file used to store the encrypted files on NTFS file system volumes. Encrypted files cannot be used unless the user has access to the keys needed to decrypt the information.

  Encryption is transparent to the user that encrypted the file. This means that you don't have to manually decrypt the encrypted file before that you can use. You can open and edit the file as you normally would. Once you encrypt a file or folder, you work with the encrypted file, or a folder like you do with any other file or folder.

  The use of EFS is similar to using permissions on files and folders. Both methods can be used to restrict access to the data. However, an attacker who gets physical access unauthorized to your encrypted files or folders will be prevented from reading. If the intruder tries to open or copy your encrypted file or folder, he or she receives an access denied message. Permissions on files and folders do not protect against unauthorized physical attacks.

  You encrypt or decrypt a folder or file by setting the property of encryption for files and folders, as you define another attribute such as read-only, compressed, or hidden. If you encrypt a folder, all files and subfolders created in the encrypted folder are automatically encrypted. It is recommended that you encrypt at the folder level.

  You can also encrypt or decrypt a file or folder using the Cipher command.

  When you work with encrypted files and folders, keep in mind the following information:

  • Only the files and folders on NTFS volumes can be encrypted. However, you can use Web distributed authoring and versioning (WebDAV), which also works with NTFS, to transfer files in encrypted form.
  • Files or compressed files can also be encrypted. If the user marks a file or folder for encryption, that file or folder will be uncompressed.
  • Encrypted files are decrypted if you copy or move the file to a volume that is not an NTFS volume.
  • Moving files unencrypted in an encrypted folder will automatically cause these files to be encrypted in the new folder. However, the reverse will not automatically decrypt files. The files must be explicitly decrypted.
  • Files marked with the system attribute cannot be encrypted, nor can files in the system root directory structure.
  • Encrypt a file or a folder does not protect against the removal or the list of files or directories. Anyone with the appropriate permissions can delete or list encrypted folders or files. For this reason, the use of EFS in combination with NTFS permissions is recommended.
  • You can encrypt or decrypt files and files located on a remote computer that has been enabled for remote encryption, but, in this version of Windows, the data that is transmitted over the network by this process is not encrypted. Other protocols, such as Secure Socket Layer/Transport Layer Security (SSL/TLS) or Internet Protocol security (IPsec) must be used to encrypt data while they are transmitted over the network. (You can also use WebDAV, as described in the first bullet, to pass the file in encrypted form.)

  EFS policy settings

  You can use Group Policy to configure a number of EFS settings.

  Allow or disallow the EFS

  You can choose to allow or prohibit the use of EFS altogether. If you do not configure the policy settings for EFS, it is OK.

  The EFS options

  If you choose to allow EFS, you can also select a number of options, such as whether to automatically encrypt the Documents folder of the user, to require a smart card for use with EFS, to cache keys created based on a smart card, to enable the encryption of the Windows page file, or to notify users to make the backup copies of their encryption keys.

  EFS certificate

  EFS encryption is based on the pairs of keys associated with certificates. In most managed environments, the certificates are issued by a certification authority (CA) running in the field. Users can automatically be issued a certificate from the CA without manual intervention. EFS settings include a drop-down models of certificates that are available in the field list so that you can specify which certificate template to use for autoenrollment.

  Note
  	The list includes all the models of certificates, present in the field. An administrator must configure the CA so that certificates can be issued. Some displayed certificates are not available.

  In cases where a certificate cannot be issued by a certification authority, EFS can use a self-signed certificate created on the local computer (there is a section in secpol.msc to create a certificate). You can choose to disable this functionality and specify a default key length.

• Artifacts R400 weird screen (integrated graphics) running Win 7 RTM

  Pretty much no matter what I do - I keep seeing weird "artificats" on my screen (integrated display and when to use an external monitor).  It is not a particular activity that requires even if switching windows exacerbates the problem.  I tried to use the pre-installed driver Win 7 and the latest drivers from Intel's RTM (Intel® Graphics Media Accelerator Driver for Windows 7 Release Candidate), and it made no difference.

  What I see on the screen, it's as if a DVI connection is bad, but I can only compress/maximize the active window and immediately cleared debris from the screen.  I have a lot of free memory and don't have many applications open at any time. If I take a screen when this happens, debris from the screen appears there too, probably isn't the output device, but something is happening with the graphics card itself.

  I disabled the Aero graphics until someone can help me understand what is happening.  I should not have done it on a new computer laptop!  What is the problem here?

  All,

  We have published a official tip on what lies on our support site.

  Visual corruption - ThinkPad R400, R500, T400, T400s, T500, W500, X 200, X200s, X 200 Tablet, X 301

  Symptom

  Visual corruption is seen on the screen. He tends to start isolated to a specific application window, but then starts quickly appear on all other windows in the application, and the office. Corruption usually appears as garbled text or images scrambled.

  Configurations affected
  The following configuration:
  Microsoft Windows Vista or Windows 7 (32-bit or 64-bit)
  Intel Virtualization Technology for Directed-IO (VT - d) is enabled in the BIOS Setup utility.
  There are two bars of memory DIMM in the system, and they have a different size (for example, 2 GB and 1 GB).
  On one of the following systems:
  ThinkPad R400(*1), R500(*2)
  T400(*1), T500(*1), T400s ThinkPad
  ThinkPad W500(*1)
  ThinkPad X 200, X200s, X 200 Tablet, X 301
  * 1: for models with switchable graphics, the system must be integrated graphics mode to see the failure.
  * 2: models with integrated only graphics.

  Workaround

  Option 1:
  Disable virtualization for directed-IO (VT - d). This can be done in the BIOS Setup utility. When the system is first start (during POST), press F1 to enter the Setup utility. Then enter the Config menu and the submenu of the CPU. Changing VT - d for persons with reduced mobility.

  Option 2:
  Make sure that there is only a single memory DIMM in the system.

  Option 3:
  Make sure the memory of two DIMMs in the system are of equal size. For example, both are 2GB.
  VT - d
  Virtualization for directed-IO (VT - d) technology is an assist of hardware for virtualization of i/o device (primary the DMA and interrupts). VT - d is not necessary to support a virtual machine running (to the knowledge of Lenovo at the moment). Some VMMs require that material help for virtualization to be activated, but it is a separate VT - d setting. In the same screen of the BIOS Setup, there is a parameter called virtualization technology, which is the most commonly used feature.
  Here is a link to the Intel site describing Vt - d.
