• Calendar icon in unity shows wrong date

  - by felix

  There is a column of icons in unity on the far left and one of them has the number "31" in big numerals. If you mouse over it it says "Google Calendar" and if you click on it you get google calendar which of course shows the correct date. Today is November 3. Shouldn't it say "3" instead? If I type "date" from the command line I get Sun Nov 3 21:19:37 GMT 2013 I see this was fixed for Chrome at least in 2011 http://gmailblog.blogspot.co.uk/2011/04/5-years-of-google-calendar-and-new.html .

• After a domain change, what can I do to recover lost traffic, rankings, impressions etc? [duplicate]

  - by Felix

  This question already has an answer here: How do I rename a domain and preserve PageRank? 3 answers I moved my site to a legacy exact-match domain I purchased about a couple of months ago. I have seen significant reduction in traffic, impressions, and rankings. I did all the right steps/best practices: change of address in GWT, map old site hierarchy and match to new site for 301 redirects etc. Indexation has gone through the Google process: old site has all but dissappeared from he index and new site is indexed, albeit with some 404 errors which I am addressing. Does anyone else who has gone through eh domain change process have any thoughts/advice? Thanks!

• What is required to create local business rich-snippets complete with sitelinks AND breadcrumbs?

  - by Felix

  I have a local business directory site. I would like to markup my business listing 'profile' level pages for display as enhanced listings/rich-snippets complete with business names, addresses and phone numbers. I would also like to display site-links and path-based breadcrumbs to help users navigate site directory hierarchy (which is deep). Is there a limit to the amount of breadcrumbs a site can leave? Is there a separate limit on the number of breadcrumbs which Google/Bing will display in the SERP? What kind of markup language(s) would be needed to best position my site to show site-links AND breadcrumbs? For example: Find a business Browse by Location State City Zip or Find a business Choose Service Browse by location State City Thanks all!

• 12.04 doesn't boot anymore after a power failure

  - by Felix

  I'm a Windows user and I have no experience with Linux and Ubuntu. I installed Ubuntu 12.04 on my netbook (Asus 1215B) and everything works fine. Yesterday I ran the "update application" and updated over 120 "things" (I have no idea what exactly). After that I was asked to reboot, and I did. Ubuntu starts again and at the load screen with these 5 dots that normally begin to change color, it freezes. After 20 minutes I took out the battery to try another reboot (yes, not the the best idea), and now nothing happens. I boot from the HDD and I get an Error BOOTMGR is missing. I have important data on the hard drive. Is there an option to get this fixed? Or if not, to at least get the data from the hard drive? Ubuntu 12.04 64-bit Edit: it is ONLY Ubuntu on this Netbook, which uses the whole 500gb HDD as 1 Partition. Filesystem is NTFS. Whole Hardware seems okay. The USB drive which i used to instl the Os was formated in fat32

• Twitter API similar to Google Alert

  - by Felix Perdana

  I am trying to create a web application which have a similar functionality with Google Alerts. (by similar I mean, the user can provide their email address for the alert to be sent to, daily or hourly) The only limitation is that it only gives alerts to user based on a certain keyword or hashtag. I think that I have found the fundamental API needed for this web application. https://dev.twitter.com/docs/api/1/get/search The problem is I still don't know all the web technologies needed for this application to work properly. For example, Do I have to store all of the searched keywords in database? Do I have to keep pooling ajax request all the time in order to keep my database updated? What if the keyword the user provided is very popular right now that might have thousands of tweets just in an hour (not to mention, there might be several emails that request several trending topics)? By the way, I am trying to build this application using PHP. So please let me know, what kind of techniques I need to learn for such web app (and some references maybe)? Any kind of help will be appreciated. Thanks in advance :) Regards, Felix Perdana

• Custom EntityNotFoundDelegate

  - by Felix

  Hi all, I get a org.hibernate.ObjectNotFoundException when I want to delete an object which doesn't exist anymore via hibernate. I just want this exception to be ignored. I could catch the exception and ignore, this would be a solution maybe. But, since there is a hibernate support for ignoring this exception through org.hibernate.cfg.Configuration#entityNotFoundDelegate, I would like to use its advantage and control it using configuration. The question is then, how can I introduce my own/custom implementation of EntityNotFoundDelegate to the org.hibernate.cfg.Configuration? Does anybody have a sample code for me? Just an additional tip, I use Spring Framework as well in my project. Here is the exception that I get: Caused by: org.springframework.orm.hibernate3.HibernateObjectRetrievalFailureException: No row with the given identifier exists: [de.mycompany.domain.ResultObject#810b1334-32d3-02b0-e044-769e0ab48e48]; nested exception is org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [de.mycompany.domain.ResultObject#810b1334-32d3-02b0-e044-769e0ab48e48] at org.springframework.orm.hibernate3.SessionFactoryUtils.convertHibernateAccessException(SessionFactoryUtils.java:660) at org.springframework.orm.hibernate3.HibernateAccessor.convertHibernateAccessException(HibernateAccessor.java:412) at org.springframework.orm.hibernate3.HibernateTemplate.doExecute(HibernateTemplate.java:424) at org.springframework.orm.hibernate3.HibernateTemplate.executeWithNativeSession(HibernateTemplate.java:374) at org.springframework.orm.hibernate3.HibernateTemplate.delete(HibernateTemplate.java:865) at org.springframework.orm.hibernate3.HibernateTemplate.delete(HibernateTemplate.java:859) at de.mycompany.utils.dao.impl.PersistentDaoImpl.delete(PersistentDaoImpl.java:50) at de.mycompany.utils.service.ServiceImpl.delete(ServiceImpl.java:68) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:307) at org.springframework.aop.framework.ReflectiveMethodInvocation.invokeJoinpoint(ReflectiveMethodInvocation.java:182) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:149) at de.mycompany.utils.service.ServiceInterceptor.invoke(ServiceInterceptor.java:43) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:171) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:204) at $Proxy3.delete(Unknown Source) ... 14 more Caused by: org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [de.mycompany.domain.ResultObject#810b1334-32d3-02b0-e044-769e0ab48e48] at org.hibernate.impl.SessionFactoryImpl$2.handleEntityNotFound(SessionFactoryImpl.java:409) at org.hibernate.proxy.AbstractLazyInitializer.checkTargetState(AbstractLazyInitializer.java:108) at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:97) at org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:140) at org.hibernate.engine.StatefulPersistenceContext.unproxyAndReassociate(StatefulPersistenceContext.java:594) at org.hibernate.event.def.DefaultDeleteEventListener.onDelete(DefaultDeleteEventListener.java:90) at org.hibernate.event.def.DefaultDeleteEventListener.onDelete(DefaultDeleteEventListener.java:74) at org.hibernate.impl.SessionImpl.fireDelete(SessionImpl.java:793) at org.hibernate.impl.SessionImpl.delete(SessionImpl.java:778) at org.springframework.orm.hibernate3.HibernateTemplate$26.doInHibernate(HibernateTemplate.java:871) at org.springframework.orm.hibernate3.HibernateTemplate.doExecute(HibernateTemplate.java:419) ... 30 more And my versions: Hibernate: 3.3.1 Spring: 2.5.6 Thanks in advance!

• ocjective-c Obtain return value from public method

  - by Felix

  I'm pretty new to objective-C (and C in general) and iPhone development and am coming from the java island, so there are some fundamentals that are quite tough to learn for me. I'm diving right into iOS5 and want to use storyboards. For now I am trying to setup a list in a UITableViewController that will be filled with values returned by a web service in the future. For now, I just want to generate some mock objects and show their names in the list to be able to proceed. Coming from java, my first approach would be to create a new Class that provides a global accessible method to generate some objects for my list: #import <Foundation/Foundation.h> @interface MockObjectGenerator : NSObject +(NSMutableArray *) createAndGetMockProjects; @end Implementation is... #import "MockObjectGenerator.h" // Custom object with some fields #import "Project.h" @implementation MockObjectGenerator + (NSMutableArray *) createAndGetMockObjects { NSMutableArray *mockProjects = [NSMutableArray alloc]; Project *project1 = [Project alloc]; Project *project2 = [Project alloc]; Project *project3 = [Project alloc]; project1.name = @"Project 1"; project2.name = @"Project 2"; project3.name = @"Project 3"; [mockProjects addObject:project1]; [mockProjects addObject:project2]; [mockProjects addObject:project3]; } And here is my ProjectTable.h that is supposed to control my ListView #import <UIKit/UIKit.h> @interface ProjectsTable : UITableViewController @property (strong, nonatomic) NSMutableArray *projectsList; @end And finally ProjectTable.m #import "ProjectsTable.h" #import "Project.h" #import "MockObjectGenerator.h" @interface ProjectsTable { @synthesize projectsList = _projectsList; -(id)initWithStyle:(UITableViewStyle:style { self = [super initWithStyle:style]; if (self) { _projectsList = [[MockObjectGenerator createAndGetMockObjects] copy]; } return self; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { // only one section for all return 1; - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSLog(@"%d entries in list", _projectsList.count); return _projectsList.count; - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // the identifier of the lists prototype cell is set to this string value static NSString *CellIdentifier = @"projectCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; Project *project = [_projectsList objectAtIndex:indexPath.row]; cell.textLabel.text = project.name } So while I think everything is correctly set, I expect the tableView to show my three mock objects in its rows. But it stays empty and the NSLog method prints "0 entries in list" into the console. So what am I doing wrong? Any help is appreciated. Best regards Felix

• Problem modifying read-only files on Samba NAS

  - by Felix Dombek

  Hi, I have files on a Samba server in the local company network and accessing them from a Windows Vista machine. Usually, if I want to delete a directory containing write-protected (read-only) files, Windows would ask "This file is read-only, are you sure?". However, when I do this with a dir on the server, Windows just tells me that I need permissions. The workaround is to remove the read-only flag from the directory and all contained files and then deleting. However, I have a TortoiseSVN versioned dir on the server, and the .svn dirs contain read-only files. I need to remove the read-only flags from the dir before every commit, or else it fails. This is quite distressing and shouldn't be so. Does someone know how to attack this problem? (If someone knows how to tell TortoiseSVN to not make its files read-only, that would probably be ok as well) ... Thanks!

• Messed up USB stick doesn't show in blkid

  - by Felix

  I was playing around with a USB stick (booting archlinux with qemu off of it and trying to perform an installation on the same stick at the same time -- brave, I know, but I was just messing around). Now, after failing to boot and install at the same time, it seems I have sort of messed up my stick. What I think happened is that I used cfdisk to wipe everything on it and create one big partition, but formatting it then failed, so now there's a big partition with no filesystem. Just to make it clear: I'm not worried for my stick, I know I can recover it at any point. What I find intriguing is that after plugging the stick into my computer (using Ubuntu), there's no (terminal) way to find out what block device (/dev/sdx) it has associated. The only way I could determine that was with GParted: But blkid shows the following: /dev/sda1: UUID="12F695CFF695B387" LABEL="System Reserved" TYPE="ntfs" /dev/sda2: UUID="A0BAA6EABAA6BC62" TYPE="ntfs" /dev/sdb1: UUID="546aec8b-9ad6-4571-b07a-adba63e25820" TYPE="ext4" /dev/sdb2: UUID="2a8b82d8-6c6e-4053-a446-bab970d93d7c" TYPE="swap" /dev/sdb3: UUID="7cbede7d-c930-4e59-9d1b-01f2d79bd092" TYPE="ext4" No trace of /dev/sdc. My question is: if I didn't have a graphical interface (to use GParted), how would I have known which block device is my stick?

• dns in a small network with router and AD domain

  - by Felix

  I have a small office network with router (running OpenWRT), Windows Domain Controller (used to be 2008R2; I just backed it up and upgraded to 2012), about a dozen AD clients (3 server and windows workstation) and several non-AD clients (network printer, PBX). The problem is that the clients can't access servers by name (only by IP). I tried all kind of permutations. Right now domain controller runs DNS server for all desktops; but unless I put an entry in hosts file - I can only get by IP. I have router as DHCP server (since not all devices are on AD); and except for Domain Controller all IP addresses, including "static", are assigned by the router. Most frustrating, some servers sometimes just work! for example, I can often get to the Linux box by name (it is part of Domain using Beyond Trust Integration Services); but I can never get to SQL Server box. Seems like non-domain devices see more names than domain members... This network should be fairly typical; but I couldn't get any guidance about how to set up DNS/DHCP service to make all nodes happy. The closest is this question, but still it's different! Thanks

• Cmd+Less Than (10.8.2) not working after Xcode (4.5.x) installed

  - by Felix Lieb

  I had to reinstall my MBP recently. I stress Cmd+Less Than a lot for switching between Xcode's main window and the Organizer for documentation. The standard OSX-shortcut for doing that is Cmd + Less Than. After installing Xcode it didn't work any longer. I saw, that Xcode uses Cmd+LT for "Edit Schemes", a rarely used option. Even after deleting the shortcut for "Edit Schemes" in Xcode, Cmd+LT didn't work. How can I get Cmd + Less Than to work again? Mac OS X Mount Lion 10.8.2 Xcode 4.5.2 I have less than 10 reputation on superuser (acutally first post here), so I can't post the answer to my question. Would yo be so kind and upvote this question, so I can officially answer the question? The question, as well as the answer is only correct, if you use German keyboard layout.

• My Windows 7 has suddenly stopped displaying Unicode symbols

  - by Felix Dombek

  For some strange reason, my computer suddenly doesn't show certain unicode characters anymore! I have no idea what happened. Affected applications include Windows Explorer (should be Japanese characters), Google Chrome (should be a heart), and Winamp (should be stars): Russian, German etc. characters are displayed normally. Chrome also displays Japanese script on websites, but not in the GUI. How can I fix it? Update: I have tried to use System Restore to fix it. I needed to go back in time quite a while because the most recent restore points didn't solve it so I used one from the middle of November. After that restore, Unicode symbols were displayed again. Then I updated my system with Windows Update again because those were removed during the restore. After that, the error occurred again! I then did a restore to a point before my new updates, but the error persists, and the old restore point (which I used before) is gone and there are currently no other snapshots of the system. Any suggestions on what to do now? Update 2: I could find a workaround: Control Panel ? Region and Language ? Administration ? Change Language for Unicode-incompatible programs to Japanese (Japan). All mentioned programs display their symbols correctly again. However, I don't consider this a fix because these programs are not usually Unicode-incompatible, and it also leads to some (non-serious) artifacts in some programs. I still welcome an answer that tells me what went wrong here and how to fix the issue.

• Web based interface for open SSL client certificates

  - by Felix

  Hi there! We are currently developing a apache2-based web application and want to invite some beta testers to give it a try. To be on the safe side, access should be provided by individual browser certificates (.p12) which are issued using a (fake) CA. Our users should be passing a complete register/login process and some of them will be granted administrative privileges within the application. That's why a preceding simple web-based authentication won't be sufficient. Atm, I am using a serverside shellscript to generate the certificates each time. Do you know about a small, web-based tool to simplify the process of generating / revoking those certificates? Maybe an overview of the CA's index.txt plus the option to revoke a cert and a link to download them directly?

• MySQL won't stop doing stuff

  - by Felix

  Sorry for the title of the question, here's my problem: I've been trying to set up some scripts that import a lot of stuff hourly from an external source. They seemed to work fine, so I set up a cronjob to run them every hour. One day later I find six or seven instances of that script just hogging the MySQL server, making it unresponsive. I killed their processes, but MySQL was still not responding. I had to kill MySQL, reboot and then MySQL started working again (who knows on what) and being unresponsive (yes, I did remove the scripts from the cronjobs). I SHOW PROCESSLISTed and killed every process I could find. Still nothing, MySQL is hogging the HDD and is at the top of top and making the server load go up in the sky. I don't know what to do, if I kill and start it again it will probably do the same thing. What should I do?

• How to choose which fields are available via LDAP from an Active Directory

  - by Felix Eve

  I'm using PHP to do an ldap search and then pull the attributes out using ldap_get_attributes. This returns an array of data (that can be seen here) however there are some fields that are missing such as Organization Title, department, company, address and telephone number. How to I make these fields available? There is a similar question here: http://www.petri.co.il/forums/showthread.php?t=15227 I've followed the steps outlined there an tried changing some access permissions but am not really sure what I'm doing and can't see any permissions that directly relate to the fields that I can see when I edit a user in the "Active Directory Users Computers" window. I am a PHP developer, not a Windows server administrator so am finding configuring an AD rather challenging so please don't assume any level of knowledge about AD. I've asked the same question on stack exchange but understand this is a more relevant place to ask.

• how to add value to windows installer property table

  - by Felix

  According to MSDN installer sets ROOTDRIVE to the local drive that can be written to having the most free space. In my situation it is a slow USB drive that I use for nightly backup, but I would prefer to use my C drive for the install folder. But somehow I can't figure out how to set this property from command line or through PowerShell. I found that it is possible, but these instructions don't make any sense

• How much space do NTFS hardlinks/symlinks occupy?

  - by Felix Dombek

  Well, I guess it must be something proportional to the original filename plus the new filename for symlinks, and only the new filename for hardlinks, but how does this affect the disk space exactly? I just made a folder with about a hundred thousand symbolic links in it, and the folder still reported 0 bytes usage. I may be mistaken, but I even think the free capacity of the drive remained the same. Then I permanently deleted the folder and the sizes still stayed the same. Could I fill up a hard disk just with symlinks? Or does NTFS have limitations in that no more than x symlinks are allowed on one drive/in one folder, so the capacity of the drive cannot be reached?

• Can I use only a HDMI monitor?

  - by Felix

  I recently found out there are such things as PC monitors with TV capabilities (or TVs that can be PC monitors), and the idea kind of tickles my fancy. I'm thinking of getting one of these gadgets, and if I do, I will connect it to my PC via HDMI (my graphics card has builtin HDMI), so that I also get sound to the TV. The reason for this is because I have a 2.1 sound system which I want to use both on the PC and the TV. Basically, I want the configuration to look like this: Cable --------> TV --> 2.1 Sound System PC --HDMI--> TV --> 2.1 Sound System My question is: can I use a setup like this? Can I not have a classic VGA monitor? Will I be able to see non-graphical interfaces (such as the BIOS, GRUB, a Linux terminal, ...) through HDMI on the TV? I use Windows 7 and Ubuntu.

• Cannot terminate process, "already terminated"

  - by felix-freiberger

  On Windows 8, I regularly get processes into a state where I can't terminate them. Skypekit.exe seems to be the process that's most likely to trigger that issue, but other processes can do that, too. When I try to terminate these processes, I sometimes get an "access denied" message, sometimes nothing happens - but every following attempt to kill that process results in an "access denied" message, too, even though I... have administrative rights (and ran the task manager with it) own that process have the right to terminate it "Process Hacker 2" shows a more detailed error message, stating that I couldn't terminate the process because it already is terminated. Still, the process is most definitely still there, because every task manager I tested still can see it. Process Hacker's "Terminator" is unable to kill such a process, but when running the "Close the process' handles" tactic, Process Hacker gets stuck himself, leaving its windows in "not responding". In that state, other task managers are in turn unable to kill Process Hacker. The only way I found to actually end these processes is to shutdown (which works without any problems). Why is this happening? How can I kill these processes?

• How can I insert auto-numbered sentences in LibreOffice Writer?

  - by Felix Dombek

  I want to achieve a formatting like this: Some text which references (1), for example because (1) might be an example sentence for some grammatical structure which is explained here. This is auto-numbered text object 1.                                                                                      (1) The number on the right is assigned automatically. If another auto-numbered object is inserted before this, it will change to (2), as will all references in the surrounding text. Some more surrounding text. How can I insert such numbered sentences and references to them in LibreOffice 3.5.1?

• Upgrade or replace?

  - by Felix

  My current PC is about four years old, although I have made upgrades to it throughout its existence. The current specs are: (old) Intel Pentium D 2.80Ghz (32K L1 / 2M L2), Gigabyte 945GCMX-S2 motherboard (old) 2.5GB DDR2 (slot0: 512MB @ 533Mhz; slot1: 2GB @ 667Mhz) (new) HIS Radeon HD 4670 - I think this is limited by the motherboard not supporting PCIe 2.0 (?) (old) WD Caviar 160GB - pretty slow (new) WD Caviar Black 640GB (if any more specs are relevant, let me know and I'll add them) Now, on to my question. I've been having performance issues lately, both in video games and in intensive applications. A couple of examples: Android application development (running Eclipse and the Android emulator) is painfully slow (on Linux). I only realized this when, at my new job as an Android dev, both tools are MUCH quicker. (I'm not sure what CPU I have there) The guys at my new job got me NFS Hot Pursuit, in which I barely get like 5-10FPS, even with graphics options turned all the way down My guess is that the bottleneck in my system is my CPU, so I'm thinking of upgrading to a Quad Core i5 + new motherboard + 4GB DDR3 (or more, 'cause I know you'll all jump and say 8GB minimum). Now: Is that a good idea? Is my CPU really a bottleneck, or is the whole system too old and I should replace it? I run Windows 7 on the old, 160GB HDD (which is on IDE, by the way). Could this slow down games as well? Should I get a new drive for Windows if I want to play new games? I know nothing about power supplies. Could that be a problem / will it be a problem if I upgrade to an i5? How come DiRT2 works on full graphics settings (pretty amazing graphics by the way) and NFS Hot Pursuit pulls only 5-10FPS?

• Tools to extract text from powerpoint pptx in linux?

  - by felix

  Any there any linux tools that will extract the text from a Powerpoint pptx file? I tried catppt but it just returns file.pptx is not OLE file or Error. abiword --to=txt file.pptx also returns an empty text file. I can open the file in libreoffice but it doesn't seem to have an "export as text" option. As a guess I also tried libreoffice --headless --convert-to txt:Text file.pptx but that doesn't even return an empty file.
