• MySQL for Excel 1.1.3 has been released

  - by Javier Treviño

  The MySQL Windows Experience Team is proud to announce the release of MySQL for Excel version 1.1.3, the  latest addition to the MySQL Installer for Windows. MySQL for Excel is an application plug-in enabling data analysts to very easily access and manipulate MySQL data within Microsoft Excel. It enables you to directly work with a MySQL database from within Microsoft Excel so you can easily do tasks such as: Importing MySQL Data into Excel Exporting Excel data directly into MySQL to a new or existing table Editing MySQL data directly within Excel MySQL for Excel is installed using the MySQL Installer for Windows. The MySQL installer comes in 2 versions   Full (150 MB) which includes a complete set of MySQL products with their binaries included in the download Web (1.5 MB - a network install) which will just pull MySQL for Excel over the web and install it when run.   You can download MySQL Installer from our official Downloads page at http://dev.mysql.com/downloads/installer/. MySQL for Excel 1.1.3 introduces the following features:   Upon saving a Workbook containing Worksheets in Edit Mode, the user is asked if he wants to exit the Edit Mode on all Worksheets before their parent Workbook is saved so the Worksheets are saved unprotected, otherwise the Worksheets will remain protected and the users will be able to unprotect them later retrieving the passkeys from the application log after closing MySQL for Excel. Added background coloring to the column names header row of an Import Data operation to have the same look as the one in an Edit Data operation (i.e. gray-ish background). Connection passwords can be stored securely just like MySQL Workbench does and these secured passwords are shared with Workbench in the same way connections are. Changed the way the MySQL for Excel ribbon toggle button works, instead of just showing or hiding the add-in it actually opens and closes it. Added a connection test before any operation against the database (schema creation, data import, append, export or edition) so the operation dialog is not shown and a friendlier error message is shown.   Also this release contains the following bug fixes:   Added a check on every connection test for an expired password, if the password has been expired a dialog is now shown to the user to reset the password. Bug #17354118 - DON'T HANDLE EXPIRED PASSWORDS Added code to escape text values to be imported to an Excel worksheet that start with an equals sign so Excel does not treat those values as formulas that will fail evaluation. This is an option turned on by default that can be turned off by users if they wish to import values to be treated as Excel formulas. Bug #17354102 - ERROR IMPORTING TEXT VALUES TO EXCEL STARTING WITH AN EQUALS SIGN Added code to properly check the reason for a failing connection, if it's a failing password the user gets a dialog to retry the connection with a different password until the connection succeeds, a connection error not related to the password is thrown or the user cancels. If the failing connection is not related to a bad password an error message is shown to the users indicating the reason of the failure. Bug #16239007 - CONNECTIONS TO MYSQL SERVICES NOT RUNNING DISPLAY A WRONG PASSWORD ERROR MESSAGE Added global options dialog that can be accessed from the Schema Selection and DB Object Selection panels where the timeouts for the connection to the DB Server and for the query commands can be changed from their default values (15 seconds for the connection timeout and 30 seconds for the query timeout). MySQL Bug #68732, Bug #17191646 - QUERY TIMEOUT CANNOT BE ADJUSTED IN MYSQL FOR EXCEL Changed the Varchar(65,535) data type shown in the Export Data data type combo box to Text since the maximum row size is 65,535 bytes and any autodetected column data type with a length greater than 4,000 should be set to Text actually for the table to be created successfully. MySQL Bug #69779, Bug #17191633 - EXPORT FAILS FOR EXCEL FILES CONTAINING > 4000 CHARACTERS OF TEXT PER CELL Removed code that was replacing all spaces typed by the user in an overriden data type for a new column in an Export Data operation, also improved the data type detection code to flag as invalid data types with parenthesis but without any text inside or where the contents inside the parenthesis are not valid for the specific data type. Bug #17260260 - EXPORT DATA SET TYPE NOT WORKING WITH MEMBER VALUES CONTAINING SPACES Added support for the year data type with a length of 2 or 4 and a validation that valid values are integers between 1901-2155 (for 4-digit years) or between 0-99 (for 2-digit years). Bug #17259915 - EXPORT DATA YEAR DATA TYPE NOT RECOGNIZED IF DECLARED WITH A DISPLAY WIDTH) Fixed code for Export Data operations where users overrode the data type for columns typing Text in the data type combobox, which is a valid data type but was not recognized as such. Bug #17259490 - EXPORT DATA TEXT DATA TYPE NOT RECOGNIZED AS A VALID DATA TYPE Changed the location of the registry where the MySQL for Excel add-in is installed to HKEY_LOCAL_MACHINE instead of HKEY_CURRENT_USER so the add-in is accessible by all users and not only to the user that installed it. For this to work with Excel 2007 a hotfix may be required (see http://support.microsoft.com/kb/976477). MySQL Bug #68746, Bug #16675992 - EXCEL-ADD-IN IS ONLY INSTALLED FOR USER ACCOUNT THAT THE INSTALLATION RUNS UNDER Added support for Excel 2013 Single Document Interface, now that Excel 2013 creates 1 window per workbook also the Excel Add-In maintains an independent custom task pane in each window. MySQL Bug #68792, Bug #17272087 - MYSQL FOR EXCEL SIDEBAR DOES NOT APPEAR IN EXCEL 2013 (WITH WORKAROUND) Included the latest MySQL Utility with a code fix for the COM exception thrown when attempting to open Workbench in the Manage Connections window. Bug #17258966 - MYSQL WORKBENCH NOT OPENED BY CLICKING MANAGE CONNECTIONS HOTLABEL Fixed code for Append Data operations that was not applying a calculated automatic mapping correctly when the source and target tables had different number of columns, some columns with the same name but some of those lying on column indexes beyond the limit of the other source/target table. MySQL Bug #69220, Bug #17278349 - APPEND DOESN'T AUTOMATICALLY DETECT EXCEL COL HEADER WITH SAME NAME AS SQL FIELD Fixed some code for Edit Data operations that was escaping special characters twice (during edition in Excel and then upon sending the query to the MySQL server). MySQL Bug #68669, Bug #17271693 - A BACKSLASH IS INSERTED BEFORE AN APOSTROPHE EDITING TABLE WITH MYSQL FOR EXCEL Upgraded MySQL Utility with latest version that encapsulates dialog base classes and introduces more classes to handle Workbench connections, and removed these from the Excel project. Bug #16500331 - CAN'T DELETE CONNECTIONS CREATED WITHIN ADDIN You can access the MySQL for Excel documentation at http://dev.mysql.com/doc/refman/5.6/en/mysql-for-excel.html You can find our team’s blog at http://blogs.oracle.com/MySQLOnWindows.

• What is the best way to store anciliary data with a 2D timeseries object in R?

  - by Mike52

  I currently try to move from matlab to R. I have 2D measurements, consisting of irradiance in time and wavelength together with quality flags and uncertainty and error estimates. In Matlab I extended the timeseries object to store both the wavelength array and the auxiliary data. What is the best way in R to store this data? Ideally I would like this data to be stored together such that e.g. window(...) keeps all data synchronized.

• What is the diffference between "data hiding" and "encapsulation"?

  - by john smith optional

  I'm reading "Java concurrency in practice" and there is said: "Fortunately, the same object-oriented techniques that help you write well-organized, maintainable classes - such as encapsulation and data hiding -can also help you crate thread-safe classes." The problem #1 - I never heard about data hiding and don't know what it is. The problem #2 - I always thought that encapsulation is using private vs public, and is actually the data hiding. Can you please explain what data hiding is and how it differs from encapsulation?

  - by Natalia Rachelson

  People turned out in droves for Steve Miranda's Apps Cloud General Session. Steve, as engaging as ever, covered our Apps strategy in the cloud and reinforced that Oracle has a complete set of cloud services including: •    Human Capital Management•    Talent Management•    Sales and Marketing•    Customer Service and Support•    Financial Management•    Procurement, Sourcing, and Inventory•    Project Portfolio Management•    Governance, Risk, and Compliance... all delivered on top of the Social, Platform, and Common Infrastructure.Steve talked about Fusion being the centerpiece of our Cloud Services. The fact that Fusion is 100 percent standards based is a big, big deal! In addition, our ERP Cloud Service is the most complete cloud service on the market. And email marketing is dead -- social marketing is where the action is. It's also where Oracle is investing heavily from a Sales & Marketing Cloud perspective. Steve covered the strategic acquisitions Oracle has made to enhance our organic Cloud offering. Specifically, Oracle bought RightNow to make our Customer Service and Support Cloud service complete. We also bought Taleo to add Recruiting and Learning capabilities to our Talent Management Cloud. Steve talked about our customers and how they are benefiting from the use of a variety of our Cloud Services. Red Robin is driving lower labor and food costs with Oracle ERP Cloud Service. He used Elizabeth Arden as the profile customer for HCM and Talent Management Service, UBS for HCM and Talent Management Service, and Brocade for Talent Management. All these customers are benefiting from a comprehensive and fully integrated HR platform that aligns compensation with performance and enhances workforce motivation and retention. At the same time, Hitachi Data Systems is using Oracle Taleo Performance Management Cloud to recruit the right competencies, pinpoint areas of improvement, and develop and monitor employee goals to support the global account organization. KLM and Overstock.com are gaining the benefits of Oracle's Customer Service and Support Service from RightNow by better engaging and serving customer needs online and through call centers. And last but not least, Graco and Key Energy are leveraging mobility features and sales forecasting and territory management capabilities within the Oracle Sales and Marketing Service. They expect to gain better visibility to sales information and drive more efficient sales campaigns and empower their sales force with data they need to make sales. Overall, Oracle Apps Cloud Services are enjoying a significant momentum in the marketplace. Steve projected an air of confidence and enthusiasm highlighting Oracle's latest successes with Cloud services.

• Why do I have to manually 'Restart Management Network' on vSphere 5 host after reboot to get networking available?

  - by growse

  I've got a couple of vSphere 5.0 hosts in a small lab environment here and I've noticed a strange behaviour. When on of the hosts gets rebooted, it is unresponsive to the network until I log into the ESX console, Press F2 to customize and select Restart management network. Once this is done, the networking works perfectly as expected. Each host has two NICs which are trunked together using Etherchannel to a Cisco 3750. The link is also a .1q VLAN trunk and the management network is configured on VLAN121 with the VM traffic configured on VLAN118. Why would the host be completely dead to the world until I physically kick it?

• Cygwin's RSYNC for large data transfer

  - by Tim Brigham

  I'm using rsync from Cygwin to do a large scale data transfer from an aging HP MSA 1000 to a new DAS attached to a different server. I have a daemon running on the remote server in read only mode and a local copy writing the files to disk. One of my servers is an image repository with over a million files spread across about 300 directories. Each file averages only a couple hundred kilobytes. More so than any other box this one is proving problematic. The rsync process will work for a while - some times 20 minutes, some times an hour - and then it simply quits and sits idle at a given file name. I have verified that the file isn't corrupt on the remote server and that the file is successfully created on the local drive. I ran the rsync client in -vv mode, which returns nothing. I checked out the logs created by the daemon. I looked at the network utilization on the interface, which is sitting idle. I looked at the AV settings to see if anything could pose a problem there. I even updated to the latest release of Cygwin. What do I need to in order to keep this connection up? EDIT: The client system is using the command rsync.exe server::Drives/f/Repo/ /cygdrive/T/Repo --archive -P -vv The server is using the command rsync.exe --daemon --no-detach --config "rsyncd.conf" The contents of rsyncd.conf: use chroot = false strict modes = false hosts allow = 192.168.100.9 log file = c:/rsyncd.log uid=0 gid=0 [Drives] path = /cygdrive read only = yes EDIT: The file server is 2003, the disk type on the array is GPT and the size is of the array is about 4 TB. EDIT: Stranger.. It looks like the process is reliably erroring out at about 175,000 files. Rsync runs fine when I pick the same directory it has problems with one at a time. EDIT: rsync version 3.0.9 protocol version 30 Copyright (C) 1996-2011 by Andrew Tridgell, Wayne Davison, and others. Web site: http://rsync.samba.org/ Capabilities: 64-bit files, 64-bit inums, 32-bit timestamps, 64-bit long ints, no socketpairs, hardlinks, symlinks, IPv6, batchfiles, inplace, append, ACLs, xattrs, iconv, symtimes A similar failure occurred when going from the same set of files with Cygwin to a Linux install. It didn't happen until several hours later than normal however.

• Fix Online Management - Which SEO Mistakes Should Be Eliminated?

  In search engines, websites are very keenly observed before being ranked and it is very obvious if we end up making certain small mistakes. However, nobody is aware about the fact that these small mistakes can cause serious blunders to their websites. The most important requirement for developers is that they should recognize their mistakes, correct them as soon as possible using good online reputation management skills and remove Google results that act against them.

• LdapErr: DSID-0C0903AA, data 52e: authenticating against AD '08 with pam_ldap

  - by Stefan M

  I have full admin access to the AD '08 server I'm trying to authenticate towards. The error code means invalid credentials, but I wish this was as simple as me typing in the wrong password. First of all, I have a working Apache mod_ldap configuration against the same domain. AuthType basic AuthName "MYDOMAIN" AuthBasicProvider ldap AuthLDAPUrl "ldap://10.220.100.10/OU=Companies,MYCOMPANY,DC=southit,DC=inet?sAMAccountName?sub?(objectClass=user)" AuthLDAPBindDN svc_webaccess_auth AuthLDAPBindPassword mySvcWebAccessPassword Require ldap-group CN=Service_WebAccess,OU=Groups,OU=MYCOMPANY,DC=southit,DC=inet I'm showing this because it works without the use of any Kerberos, as so many other guides out there recommend for system authentication to AD. Now I want to translate this into pam_ldap.conf for use with OpenSSH. The /etc/pam.d/common-auth part is simple. auth sufficient pam_ldap.so debug This line is processed before any other. I believe the real issue is configuring pam_ldap.conf. host 10.220.100.10 base OU=Companies,MYCOMPANY,DC=southit,DC=inet ldap_version 3 binddn svc_webaccess_auth bindpw mySvcWebAccessPassword scope sub timelimit 30 pam_filter objectclass=User nss_map_attribute uid sAMAccountName pam_login_attribute sAMAccountName pam_password ad Now I've been monitoring ldap traffic on the AD host using wireshark. I've captured a successful session from Apache's mod_ldap and compared it to a failed session from pam_ldap. The first bindrequest is a success using the svc_webaccess_auth account, the searchrequest is a success and returns a result of 1. The last bindrequest using my user is a failure and returns the above error code. Everything looks identical except for this one line in the filter for the searchrequest, here showing mod_ldap. Filter: (&(objectClass=user)(sAMAccountName=ivasta)) The second one is pam_ldap. Filter: (&(&(objectclass=User)(objectclass=User))(sAMAccountName=ivasta)) My user is named ivasta. However, the searchrequest does not return failure, it does return 1 result. I've also tried this with ldapsearch on the cli. It's the bindrequest that follows the searchrequest that fails with the above error code 52e. Here is the failure message of the final bindrequest. resultcode: invalidcredentials (49) 80090308: LdapErr: DSID-0C0903AA, comment: AcceptSecurityContext error, data 52e, v1772 This should mean invalid password but I've tried with other users and with very simple passwords. Does anyone recognize this from their own struggles with pam_ldap and AD? Edit: Worth noting is that I've also tried pam_password crypt, and pam_filter sAMAccountName=User because this worked when using ldapsearch. ldapsearch -LLL -h 10.220.100.10 -x -b "ou=Users,ou=mycompany,dc=southit,dc=inet" -v -s sub -D svc_webaccess_auth -W '(sAMAccountName=ivasta)' This works using the svc_webaccess_auth account password. This account has scan access to that OU for use with apache's mod_ldap.

• Any way to recover ext4 filesystems from a deleted LVM logical volume?

  - by Vegar Nilsen

  The other day I had a proper brain fart moment while expanding a disk on a Linux guest under Vmware. I stretched the Vmware disk file to the desired size and then I did what I usually do on Linux guests without LVM: I deleted the LVM partition and recreated it, starting in the same spot as the old one, but extended to the new size of the disk. (Which will be followed by fsck and resize2fs.) And then I realized that LVM doesn't behave the same way as ext2/3/4 on raw partitions... After restoring the Linux guest from the most recent backup (taken only five hours earlier, luckily) I'm now curious on how I could have recovered from the following scenario. It's after all virtually guaranteed that I'll be a dumb ass in the future as well. Virtual Linux guest with one disk, partitioned into one /boot (primary) partition (/dev/sda1) of 256MB, and the rest in a logical, extended partition (/dev/sda5). /dev/sda5 is then setup as a physical volume with pvcreate, and one volume group (vgroup00) created on top of it with the usual vgcreate command. vgroup00 is then split into two logical volumes root and swap, which are used for / and swap, logically. / is an ext4 file system. Since I had backups of the broken guest I was able to recreate the volume group with vgcfgrestore from the backup LVM setup found under /etc/lvm/backup, with the same UUID for the physical volume and all that. After running this I had two logical volumes with the same size as earlier, with 4GB free space where I had stretched the disk. However, when I tried to run "fsck /dev/mapper/vgroup00-root" it complained about a broken superblock. I tried to locate backup superblocks by running "mke2fs -n /dev/mapper/vgroup00-root" but none of those worked either. Then I tried to run TestDisk but when I asked it to find superblocks it only gave an error about not being able to open the file system due to a broken file system. So, with the default allocation policy for LVM2 in Ubuntu Server 10.04 64-bit, is it possible that the logical volumes are allocated from the end of the volume group? That would definitely explain why the restored logical volumes didn't contain the expected data. Could I have recovered by recreating /dev/sda5 with exactly the same size and disk position as earlier? Are there any other tools I could have used to find and recover the file system? (And clearly, the question is not whether or not I should have done this in a different way from the start, I know that. This is a question about what to do when shit has already hit the fan.)

• What is the difference between "data hiding" and "encapsulation"?

  - by Software Engeneering Learner

  I'm reading "Java concurrency in practice" and there is said: "Fortunately, the same object-oriented techniques that help you write well-organized, maintainable classes - such as encapsulation and data hiding -can also help you create thread-safe classes." The problem #1 - I never heard about data hiding and don't know what it is. The problem #2 - I always thought that encapsulation is using private vs public, and is actually the data hiding. Can you please explain what data hiding is and how it differs from encapsulation?

• When is a glue or management class doing too much?

  - by jprete

  I'm prone to building centralized classes that manage the other classes in my designs. It doesn't store everything itself, but most data requests would go to the "manager" first. While looking at an answer to this question I noticed the term "God Object". Wikipedia lists it as an antipattern, understandably. Where is the line between a legitimate glue class, or module, that passes data and messages from place to place, and a class that is doing too much?

• Correcting tree from messed up file tree in NTFS partition

  - by Fullmooninu

  It's a real messed situation, but I'm quite at the end of my options. It's my personal hardrive, so it's very important for me, and yes, I have no backup =( The short story: 1) I have two discs. One with Windows, and another where I had a bit of empty space at the front of the disk, so i could install Linux. The rest was occupied by a 1.8TB NTFS partition filled with data. 2) I installed Linux, and after a while realized there was not enough space for everything, so I tried using Gparted, and told it to re-size the NTFS partition, to a lesser size. 3) The system jammed. I had to reboot and broke the Resizing operation. Here's what I did to fix it: a) Rebooted into Linux Live, and used Testdisk,to deep analyze the disk, and recover the possible partitions. It found several versions of the NTFS partitions, probably made during the resizing. I told Testdisk to open every one of them, and only one could list its files. When trying to open the other options on Testdisk, it showed an error message. I assumed the one without errors, to be the correct one, and I told Testdisk to recover the partition, and write a new MBR. b) The partition had errors, and Linux has a NTFS fixing tool, used it, but the system still had errors. c) So I booted into windows and use chkdsk to correct all errors in the partition. d) Everything seems fine, but now, back in Windows, when I open one file, it opens another file, or part of another file. As in, some files took up the position of other files. What I think happened is that I recovered an old tree, and not the most current one. And that one just happened to be intact, while the most recent one was damaged. As such, the files that were moved during the failed resizing, were now, during the automatic correction, assumed wrongly to be in their correct places. So when I open a file, it tries to open another one. Radiohead - Creep.mp3 will open and it will actually be a bit from another song, or even code from a jpg. Some files seem to be all right, but others have seemed to have had their position taken by others. Anyone knows of something really powerful that can help me solve this?
