• Last-modified date not showing up in indexed documents

  - by Jared

  We have tried everything, pushing feeds, setting up fields in "document dates" screen to enable all documents in the index to contain a value for Last-modified date. Nothing seems to make documents retain a "last-modified date" in the index. How does one enable a last-modified date for all documents in the index? Note: the meta value will come from an external xml source (not a database). Followed the google instructions for our gsa version (6.4.0.G.22). Yes I know the GSA version is quite old, we've been told by our google-representative support team themselves, that updating the GSA to the latest version "should" resolve the problem, and by "should" I mean, their GSA did the same thing (no last-modified date) and updating our GSA is another can of worms story :)

• C++ and function pointers assessment: lack of inspiration

  - by OlivierDofus

  I've got an assessment to give to my students. It's about C++ and function pointers. Their skill is middle: it the first year of a programming school after bachelor. To give you something precise, here's a sample of a solution of one of 3 exercices they had to do in 30 minutes (the question was: "here's a version of a code that could be written with function pointers, write down the same thing but with function pointers"): typedef void (*fcPtr) (istream &); fcPtr ArrayFct [] = { Delete , Insert, Swap, Move }; void HandleCmd (const string && Cmd) { string AvalaibleCommands ("DISM"); string::size_type Pos; istringstream Flux (Cmd); char CodeOp; Flux >> CodeOp; Pos = AvalaibleCommands.find (toupper (CodeOp)); if (Pos != string::npos) { ArrayFct [Pos](Flux); } } Any idea where I could find some inspiration? Some of the students have understood the principles, even though it's very hard for them to write C++ code. I know them, I know they're clever, and I'm pretty sure they should be very good project managers. So, writing C++ code is not that important after all. Understanding is the most important part (IMHO). I'm wondering about maybe break the habits, and give half of the questions about the principle, or even better, give some sample in other language and ask them why it's better to use function pointers instead of classical programming (usually a big switch case). Any idea where I could look? Find some inspiration?

• Syslog permissions

  - by Niels Kristian

  I'm using the $InputFile facility in rsyslog to monitor various log files scattered around my ubuntu 12.04 server. E.g. nginx, unicorn, rails, postgres, cron etc. Now my problem is, that some of these log files are created with -rw-r----- right, so rsyslog doesn't have read rights. Since I install most of the programs using apt-get, and therefore didn't change anything from default. So, in other words, I would like not to modify every singe log file / daemon to have the right permissions, if I instead could give syslog read access to all of them at once. But the question is - can I do that, and is it the "right thing to do"?

• SQLRally Nordic gets underway

  - by Rob Farley

  PASS is becoming more international, which is great. The SQL Community has always been international – it’s not as if data is only generated in North America. And while it’s easy for organisations to have a North American focus, PASS is taking steps to become international. Regular readers will be aware that I’m one of three advisors to the PASS Board of Directors, with a focus on developing PASS as a more global organisation. With this in mind, it’s great that today is Day 1 of SQLRally Nordic, being hosted in in Sweden – not only a non-American country, but one that doesn’t have English as its major language. The event has been hosted by the amazing Johan Åhlén and Raoul Illyés, two guys who I met earlier this year, but the thing that amazes me is the incredible support that this event has from the SQL Community. It’s been sold out for a long time, and when you see the list of speakers, it’s not surprising. Some of the industry’s biggest names from Microsoft have turned up, including Mark Souza (who is also a PASS Director), Thomas Kejser and Tobias Thernström. Business Intelligence experts such as Jen Stirrup, Chris Webb, Peter Myers, Marco Russo and Alberto Ferrari are there, as are some of the most awarded SQL MVPs such as Itzik Ben-Gan, Aaron Bertrand and Kevin Kline. The sponsor list is also brilliant, with names such as HP, FusionIO, SQL Sentry, Quest and SolidQ complimented by Swedish companies like Cornerstone, Informator, B3IT and Addskills. As someone who is interested in PASS becoming global, I’m really excited to see this event happening, and I hope it’s a launch-pad into many other international events hosted by the SQL community. If you have the opportunity, thank Johan and Raoul for putting this event on, and the speakers and sponsors for helping support it. The noise from Twitter is that everything is going fantastically well, and everyone involved should be thoroughly congratulated! @rob_farley

• Recovering from 'grub rescue>' crash

  - by DocSalvage

  I did a dumb thing... I forgot that Ubuntu 10.04 (Lucid) switched to Grub2 which puts a ton of *.mod files (kernel modules) in /boot/grub. I thought they were soundtrack files put there erroneously and moved them. Needless to say, the next reboot was traumatic. I was presented with something I had no memory of ever seeing... a 'grub rescue' prompt. With the help of how-to-fix-error-unknown-filesystem-grub-rescue however, I was able to recover... Discovered that Grub Rescue does not have 'cd', 'cp' or any other filesystem commands except its own variation of 'ls'. So first I had to find the partition with the /boot directory containing vmlinuz... and other boot image files... (failed attempts not shown) grub rescue> ls (hd0,4) (hd0,3) (hd0,2) (hd0,1) grub rescue> ls (hd0,2)/boot ... grub ... initrd.img-2.6.32-33-generic ... vmlinuz-2.6.32-33-generic Then manually boot from 'grub rescue' prompt (no command history either!)... grub rescue> set root=(hd0,2)/boot grub rescue> insmod linux grub rescue> linux (hd0,2)/boot/vmlinuz-2.6.32-33-generic grub rescue> initrd (hd0,2)/boot/initrd.img-2.6.32-33-generic grub rescue> boot This boots and crashes to the BusyBox prompt which DOES have some rudimentary filesystem commnds. Then I moved the *.mod files back to the /boot/grub directory... busybox> cd /boot busybox> mv mod/* grub busybox> reboot The reboot was successful but that was a lot of work. Is there an easier way?

• Understanding List formatting in MSWord

  - by John

  I've never understood how formatting works in MSWord for lists... it mostly just works but sometimes becomes incredibly stubborn about enforcing styles you don't want, especially when copy-pasting into a list and working with multiple, multi-layer lists. What are some good ways to understand how it works, so one can work with Word, instead of fighting against it? Here's an example... I want a list like: 1)first test CHECK: a)something b)another thing 2)another test CHECK: a)it works b)it doesn't crash I find Word really doesn't like this... I try creating one mini-list and copy pasting but typically the numbering on the sub-lists doesn't re-start automatically, etc. I'm using Word 2007 but I remember it being this way in earlier versions too.

• My boss is feuding with his boss. My workload is expanding What should I do?

  - by steve

  These two have always had a somewhat shaky relationship when they were on the same level. The other guy was recently promoted to director and now my boss reports to him. On the surface, they appear to get along when they get together, but my boss despises the man and badmouths him every chance that he gets (to peers, subordinates, etc). He believe that the director is setting him up to fail. The Director and upper management is holding my boss responsible for the not-so-great performance by the team as of late. He's been playing games to make my boss look bad. Due to lay offs, we don't have the manpower to deliever the results that we did before...but expectations have not lowered...and my boss is taking the heat for it. Now he's on the warpath and starting to micromanage. He's giving everyone more work. He's forcing us midlevel guys to take responsibility for the level one techs' performance. I'm spending less and less time coding....and more time babysitting vendors, techs, etc. I'm not so sure that's a bad thing because I'm sorta burnt out on coding, but I don't really care for the idea of having to be responsible for others poor performance....isn't that the manager's job? Anyway, do you guys have any suggestions on dealing with the situation?

• How do I get rid of Adobe Download Akamai software on a Mac?

  - by CT

  I installed Adobe's Download Manager Software when I was downloading a CS4 trial. It was called Akamai. I can not seem to get rid of this pesky thing. I have Little Snitch installed so I was annoyed that it showed that this app would phone home for updates every login. I felt this was an unnecessary process I wanted rid of. I've uninstalled it using App Cleaner. Now on login the Akamai app does not produce any Little Snitch prompts. "SoftwareUpdateCheck" does. SoftwareUpdateCheck wants to connect to a950.gi3.akamai.net on TCP 80. SoftwareUpdateCheck is /System/Library/CoreServices/SoftwareUpdate.app/Contents/Resources/SoftwareUpdateCheck. How do I rid myself of this? Mac OS X 10.6

• Apache only transferring partial content from a Samba share

  - by thaBadDawg

  I have an Apache server running on CentOS 5.3. It currently hosts 12 sites with no known issues. (I say this to point out that up to this point my Apache installation has performed flawlessly) I'm adding a new site where the DocumentRoot of the new VirtualHost is a Samba share. When at the command line of the server I can cp video.m4v ~ and the whole file is copied properly to my home directory. But when I try to access the file from IE/Firefox/Safari/Chrome it only passes back a partial result of 33k. The same thing is happening with my image and audio files. If I make the files local to the server by copying them from the share and then serving them up then the files transfer. Any ideas?

• Suscribers locking during snapshot replication

  - by remi_bourgarel

  Hi all :) Here is my architecture : I have a main server and 4 replica (the servers are synchronized with snapshot replication). The replication is working fine, except for one thing : during the replication a lot of SELECT request on one of the replica fail with a time-out. Here are my questions : Can I avoid these time-out ? If I can't : how can I detect the start and the end of the replication to redirect all the request on one of the replica to the main ? Thanks Sorry if you already answered to that kind of question but I couldn't find anything.

• HDMI video output not working for external monitor

  - by user291852

  I have installed from scratch ubuntu GNOME 14.04 with gnome-flashback on my old HP HDX 16 laptop (core 2 duo p8600 + nvidia GT9600M + 4GB of ram) and I have problems with the HDMI output (I use it to extend my desktop on a dell U2412M 1920x1200 monitor). In the following I summarize the configurations that I have tried: Using the open source nouveau drivers, only the laptop monitor works, no signal from the external monitor connected to the HDMI output. However, the output of the xrandr command show that the HDMI output is connected with the correct resolution 1920x1200 (I find this thing really weird). Nouveau drivers with VGA connection works without problems on the external monitor, but the image is blurry compared to the HDMI connection. Using the nvidia drivers (I have tried different versions: nvidia-331-updates and the xorg-edgers versions nvidia-334 and nvidia-337) the HDMI output works, but I have system instabilities, random crashes and display freezes. I can't even enter in terminal mode with ctrl-alt-f1, so I have to manually shut down the laptop with the power button. I really would like to use the HDMI output with the nouveau drivers to avoid the system instabilities that I experienced with the nvidia drivers, but I can't figure out how to make it works.

• Game-a-Week One

  - by Matt Christian

  Anyone who chats with me on a semi-regular basis knows I am absolutely horrible at completing something from beginnning to end.  Often times I'll begin something, lose interest at some point, and end up moving onto the next thing.  For example, I have 1/2 a full game created, 1/3 of a novel written, and half of a model set created.  Needless to say, unless I have some sort of pressure to finish something I don't stick to it. Recently however one of my online buddies challenged me to create a simple game.  The start date was last Thursday and the final game needed to be delivered by this next Sunday (giving me just over a week).  However, I am going out of town this Friday so will need to deliver it by Thursday, giving me exactly 1 week to develop a game.  Here is what the game needed to include: The player should be able to shoot Shooting things should score points Sounds very simple, but given a single week to produce all art assets plus the game isn't an easy task.  So far I've developed: An animated Main Menu that loads via script files, allows the user to start a new game or exit the game The game is 3D and the player can move around the play area with an 'over-the-shoulder' camera HUD elements are drawn to display the player's current score When the player presses Esc they are shown a pause menu where they can resume the game by pressing Esc again, or quit the game by pressing Space There are also 2 items implemented that don't work perfectly: JigLibX physics library implementation On the main menu there is an arrow symbol that rotates to always point at your mouse I've got 2 days of development left so hopefully I can get collision working, some of the art cleaned up, and some more of the camera functionality working.  Also, I'll need to take some time to package the game up which hopefully shouldn't take too long.

• Explanation on how "Tell, Don't Ask" is considered good OO

  - by Pubby

  This blogpost was posted on Hacker News with several upvotes. Coming from C++, most of these examples seem to go against what I've been taught. Such as example #2: Bad: def check_for_overheating(system_monitor) if system_monitor.temperature > 100 system_monitor.sound_alarms end end versus good: system_monitor.check_for_overheating class SystemMonitor def check_for_overheating if temperature > 100 sound_alarms end end end The advice in C++ is that you should prefer free functions instead of member functions as they increase encapsulation. Both of these are identical semantically, so why prefer the choice that has access to more state? Example 4: Bad: def street_name(user) if user.address user.address.street_name else 'No street name on file' end end versus good: def street_name(user) user.address.street_name end class User def address @address || NullAddress.new end end class NullAddress def street_name 'No street name on file' end end Why is it the responsibility of User to format an unrelated error string? What if I want to do something besides print 'No street name on file' if it has no street? What if the street is named the same thing? Could someone enlighten me on the "Tell, Don't Ask" advantages and rationale? I am not looking for which is better, but instead trying to understand the author's viewpoint.

• For large files compress first then transfer or rsync -z? which would be fastest?

  I have a ton of relativity small data files but they take up about 50 GB and I need them transferred to a different machine. I was trying to think of the most efficient way to do this. Thoughts I had were to gzip the whole thing then rsync it and decompress it, rely on rsync -z for compression, gzip then use rsync -z. I am not sure which would be most efficient since I am not sure how exactly rsync -z is implemented. Any ideas on which option would be the fastest?

• (Vista) Discover what app is reserving a shortcut key?

  - by Eddie Parker

  My problem is this: I've always managed to map WIN+V to foobar2000's "Next song" keyboard shortcut. For some reason, on this new machine, I can't. I've done this before on Vista, so the only thing I can think of is that some other application is holding onto this shortcut key. When I try to assign the shortcut key in foobar2000, nothing registers. When I press it outside of foobar2000, nothing occurs either. I'm at a loss as to how to proceed. Are there any apps to see what hooks are being requested by what application? Or is there a better way of diagnosing this?

• Wake timers don't wake computer from sleep mode

  - by Joe

  I'm got a custom built PC running 64 bit Windows 7 Ultimate. So far everything works great except for one thing: it will not wake up from sleep mode for a wake timer or scheduled task. Sleep mode itself works great. If it's sleeping, it wakes successfully when I press the power button, mash the keyboard, wiggle the mouse, or send a WOL packet. The only problem is wake timers. I even tried the program WakeupOnStandBy but it looks like that uses wake timers, so it doesn't do anything for me either. And yes, wake timers are enabled: Any ideas on how to fix the problem, or troubleshoot it? I'd imagine that there would be a log somewhere telling me exactly why the wake timers are having trouble, but if there is I haven't found it.

• Windows XP Disc: corrupt or not corrupt?

  - by Wesley

  Hi all, I just finished one of my builds and am trying to install Windows XP onto it. Here are the specs beforehand... Intel Pentium 4 Northwood 2.4 GHz (512KB L2, 533MHz FSB) QDI Superb 4 Motherboard 2x 1GB PC3200 DDR RAM Seagate 80GB IDE HDD Bestec 250W PSU 16MB NVIDIA TNT2 Pro Samsung DVD-ROM USB 2.0 PCI Card Generic PCI Modem The issue right now is that when I'm running through the Windows Setup from my XP Pro SP3 disc, partway through the setup says that a random file on the disc is corrupt and the computer needs to be restarted. Every time I tried booting it up, a different file was noted as corrupt. However, I tested the same disc on another computer and the Windows XP disc ran to the end of the setup screen without error. I tried this on another computer and the same thing. What could possibly be happening on this one build to cause it errors during the Windows Setup? Thanks in advance.

• How not to suffer from ideologists when you're a pragmatic person?

  - by Lukas Eder

  My story: I'm a pragmatic person. Sometimes, the most simple solution to a problem to get the job done is the one that fits best for me, if its not an utter blasphemy and reproach to any design principles. Check out my answer to this question on stackoverflow. Simple. Works. Was accepted. Could be improved. Is clearly not perfect. And along comes this guy. He downvotes me, comments on the question how his answer is better, more accurate etc and calls me "plain wrong". Reminds me of this comic strip. :-) While on stackoverflow I can laugh at these things because those people are far away, in the real world I'm suffering from ideologies every now and then. Heck, I'm not creating a miracle piece of software, I need to keep that huge legacy thing running, and it's an adventure to me every day. I don't have the time or passion to beautify my code (or other people's code) to that extent. My question(s): How do you deal with ideologies / ideologists, when you're a pragmatic person? How do you deal with pragmatism / pragmatists, when you're an ideologic person? I'm interested in both point of views. Tell me your experience. But please, be fair, somewhat objective, and understand that you may NOT be entirely correct and your opinion is NOT the only true one... :-)

• Internet Connectivity Issue

  - by MastaChief11

  Lately, I have been having issues connecting to the internet on one of my computers. The computer I am using now, however, is on the same network as the computer I am posting from. The issues seemed to randomly start about 2 days ago, and the only thing that seemed to fix the issue was to connect to Hotspot Shield VPN. I do not get any yellow warning signs by the Wi-Fi icon in the taskbar. I am sometimes able to use Google search, but I can never go to a website. I am also not able to re-install Hotspot Shield or update Flash because they have to connect to their company's servers. I have tried other VPN services just to see if it would fix anything, but as I expected, nothing changed. I am unsure of how I can fix the issue, and I appreciate all help given. I am running Windows 7 64 Bit Pro on a custom-built computer. Thanks.

• How to troubleshoot a service failure?

  - by AngryHacker

  I get a GPF dialog box out of the blue fairly often (like about 2 hours after I turn on the computer). It basically says that svchost.exe had a failure... (see the corresponding Event Log entry below). Event Type: Error Event Source: Application Error Event Category: (100) Event ID: 1000 Date: 5/18/2010 Time: 7:41:16 PM User: N/A Computer: DKHA-IPSA Description: Faulting application svchost.exe, version 5.1.2600.5512, faulting module ole32.dll, version 5.1.2600.5512, fault address 0x0004eaa9. Shortly after this error pops up, the computer pretty much grinds to a halt (e.g. some UI elements on the desktop simply do not respond). And I have to do a hard reboot. How do I troubleshoot this type of thing? P.S. The PC has all the latest patches and nothing is missing in the Device Manager.

• Thunderbird 3.0 - how to prevent new message indicator from clearing?

  - by Joe Casadonte

  I just installed Thunderbird 3.0 and there are a few things driving me batty. When new email is delivered it has a faint star to the left of the subject (this is different than the new star column thing). In the old days (i.e. last week) the new message indicator wouldn't go away until I read the message or left the folder and returned. Now, as soon as I do anything with any email message, all new message indicators are cleared. How can I go back to the old behavior? Thanks!

• How do I restore a backup of my keyring (containing ssh key passprases, nautilus remote filesystem passwords and wifi passwords)?

  - by con-f-use

  I changed the disk on my laptop and installed Ubuntu on the new disk. Old disk had 12.04 upgraded to 12.10 on it. Now I want to copy my old keyring with WiFi passwords, ftp passwords for nautilus and ssh key passphrases. I have the whole data from the old disk available (is now a USB disk and I did not delete the old data yet or do anything with it - I could still put it in the laptop and boot from it like nothing happend). The old methods of just copying ~/.gconf/... and ~/.gnome2/keyrings won't work. Did I miss something? 1. Edit: I figure one needs to copy files not located in the users home directory as well. I copied the whole old /home/confus (which is my home directory) to the fresh install to no effect. That whole copy is now reverted to the fresh install's home directory, so my /home/confus is as it was the after fresh install. 2. Edit: The folder /etc/NetworkManager/system-connections seems to be the place for WiFi passwords. Could be that /usr/share/keyrings is important as well for ssh keys - that's the only sensible thing that a search came up with: find /usr/ -name "*keyring* 3. Edit: Still no ssh and ftp passwords from the keyring. What I did: Convert old hard drive to usb drive Put new drive in the laptop and installed fresh version of 12.10 there Booted from old hdd via USB and copied its /etc/NetwrokManager/system-connections, ~/.gconf/ and ~/.gnome2/keyrings, ~/.ssh over to the new disk. Confirmed that all keys on the old install work Booted from new disk Result: No passphrase for ssh keys, no ftp passwords in keyring. At least the WiFi passwords are migrated.

• In *nix, how to determine which filesystem a particular file is on?

  - by smokris

  In a generic, modern unix environment (say, GNU/Linux, GNU/Solaris, or Mac OS X), is there a good way to determine which mountpoint and filesystem-type a particular absolute file path is on? I suppose I could execute the mount command and manually parse the output of that and string-compare it with my file path, but before I do that I'm wondering if there's a more elegant way. I'm developing a BASH script that makes use of extended attributes, and want to make it Do The Right Thing (to the small extent that it is possible) for a variety of filesystems and host environments.

• Why would a terminal server be kicking users off after about 5 minutes?

  - by Matt

  I have a terminal server that was restored from an old 1U server to an IBM HS20 Blade running ESXi. The restore was using shadow protect hardware independent restore. All appeared to be functioning well but we're finding that users are being periodically kicked off after around 5 minutes or so. The interesting thing is it doesn't appear to be a simple disconnect but the whole session has gone like it was logged out. There is nothing significant in the event log, and certainly nothing from terminal services that is logged. I've also checked the client computers and from the client computers logged into our other terminal server and there wasn't any issues there. It doesn't appear to be network related. Any ideas?
