• Netbeans automatically changes the file owner when updating files

  - by Alon_A

  We use Netbeans IDE 7.2 to edit our PHP files. In the Run Configuration it is configured as Remote Web Site to automatically save the changes on our web server (Centos OS 6.3). The problem is that every time it is updating the files the owner of the file is changed from apache:apache to userThatUploadedTheFile:users. This causes us problems with SOAP cache files that are configured with apache:apache ownership, and we need to manually chownit back to apache:apache. We've checked the "Preserve Remote File Permissions" checkbox, so the permissions are not changed, only the owner. Is there any solution to preserve the ownership ?

• Create shortcut key to insert new row using Excel 2010

  - by Dave Jarvis

  Tried to create a macro in Excel to insert a row: Sub InsertRow() ' ' InsertRow Macro ' ' Keyboard Shortcut: Ctrl+Shift+I ' Selection.EntireRow.Insert End Sub However, this does not insert a new row without first manually selecting a row. Every solution I've found requires that a row be highlighted before inserting a new row. See also: http://www.shortcutworld.com/en/win/Excel_2010.html How would you create a shortcut key (e.g., Ctrl+Shift+J) to highlight the current row and insert a new row? Thank you! Update Looks like Shift+Space highlights the current row.

• Best way to solve the game 'bricolage'

  - by maggie

  I am trying to solve the following game http://www.hacker.org/brick/ using some kind of AI. The target of this game is to finally clear the board by clicking on groups of at least 3 bricks of the same color and removing them. If a group is disappearing the remaining bricks above will fall down or be moved left if a column got no bricks left. The higher the level - more colors and larger board. I already guessed that a pure bruteforce approach wont scale nice for higher levels. So i tried to implement a monte carlo like approach which worked ok for the first levels. But i am still not confident i will make the maximum level of 1052 with this. Currently i am stuck @~ level 100 :) The finding of the solution takes too much time... Hoping that there is a better way to do this i read some stuff about neural networks but i am really at the beginning of this. Before becoming obsessed by ANNs i want to be sure it is the right way for my problem. So my question is: Does it make any sense to apply an ANN to this game? Any suggestions?

• How to optimize process of outlook files (*msg) conversion to .pdf?

  - by Lilly

  The aim is to convert several messages from Microsoft Outlook (2003 and/or 2007 versions) to .pdf files. Condition: One message should generate a corresponding single pdf file. If possible, pdf file should be named with date format YYYY-MM-DD (e.g. 2011-02-16.pdf). The current process, limited by softwares such as CutePDF, requires the conversion performed one message at a time. I'm looking for a solution that allows the conversion of several messages at once, but under the condition abovementioned (mainly: one message = one pdf file).

• Can't connect nonlocally after 12.10 upgrade

  - by user101815

  I've just upgraded one of my systems from 12.04 to 12.10. Now I can't connect on that system beyond my local network. Connections within the local network seem to work fine, and I can make nonlocal connections from other machines (like the one I'm asking this question from). I suspect that some routing information has been messed up, but I don't know where to look for it. It's not a nameserver problem -- pinging outside sites by their IP addresses doesn't work either. I have another laptop next to this one, also running Kubuntu 12.10. On the one that can't connect, arp produces no output. On the other one, it produces 192.168.0.1 ether 00:23:69:fa:ce:ae C wlan0 On the working machine, the output of netstat starts with some tcp entries. On the nonworking one, those entries are absent. I asked this question on the Ubuntu forum but haven't gotten any answers there. One further complication: since the troublesome machine has no outside connection, it's extremely difficult to download anything to it. For what it's worth, "ping 8.8.8.8" produces "connect: Network is unreachable". Update: after a lot of fiddling, I have my external world back. I don't know what the key action was, but the first indication of progress was that "ping 8.8.8.8" worked. At that point I still didn't have a working nameserver, so external URLs didn't work. But I did this (based on an online post, of course): sudo dpkg-reconfigure resolvconf and answered Yes to all prompts. That did the trick!! Apparently my problem was unique, or close to it, since I couldn't find any online references to it: local net working, remote net not working, including explicit IP addresses. So I suppose that if no one else has this problem, no one cares about the solution!!

• How can I remove unwanted cropped pages from Acrobat

  - by Servant

  Executing the crop command in Acrobat from a 3000pt * 2000pt document to 1500pt*1800pt only hides the document outside of the new boundaries but the original document still remains without change; if anyone uses the touch-up tool and moves the content, all "hidden" information outside the cropped page may appear again by dragging it into view. The page acting as a window (or a mask) to display the 3000pt * 2000pt. I am wondering if there is a solution to crop permanently the document without reprinting it again into PDF file? Please find pictures attached: http://i.stack.imgur.com/5JTPg.png http://i.stack.imgur.com/HPokv.png

• "Unmet Dependencies" problem when trying apt-get install

  - by GChorn

  Anytime I try to install python packages using the command: sudo apt-get install python-package I get the following output: Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: linux-headers-generic : Depends: linux-headers-3.2.0-36-generic but it is not going to be installed linux-headers-generic-pae : Depends: linux-headers-3.2.0-36-generic-pae but it is not going to be installed linux-image-generic : Depends: linux-image-3.2.0-36-generic but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). This seems to have started when these same three packages showed up in Ubuntu's Update Manager and kicked an error when I tried to install them there. Based on the suggestion in the output above, I tried running: sudo apt-get -f install But this only gave me several instances of the following error: dpkg: error processing /var/cache/apt/archives/linux-image-3.2.0-36-generic_3.2.0-36.57_i386.deb (--unpack): unable to create `/lib/modules/3.2.0-36-generic/kernel/drivers/net/wireless/ath/carl9170/carl9170.ko.dpkg-new' (while processing `./lib/modules/3.2.0-36-generic/kernel/drivers/net/wireless/ath/carl9170/carl9170.ko'): No space left on device Now maybe I'm way off-base here, but I'm wondering if the error could be coming from the "No space left on device" part? The thing is, I'm running Ubuntu as a VirtualBox VM but I've got it set to dynamically increase its virtual hard drive space as needed, so why am I still getting this error? Here's my output when I use dh -f: Filesystem Size Used Avail Use% Mounted on /dev/sda1 6.9G 5.7G 869M 88% / udev 494M 4.0K 494M 1% /dev tmpfs 201M 784K 200M 1% /run none 5.0M 0 5.0M 0% /run/lock none 501M 76K 501M 1% /run/shm VB_Shared_Folder 466G 271G 195G 59% /media/sf_VB_Shared_Folder When I perform sudo apt-get -f install and the system says, After this operation, 192 MB of additional disk space will be used. Does that mean 192 MB of my virtual machine's current memory, or 192 MB on top of the rest of my free space? As I said, my machine normally dynamically allocates additional memory from the host machine, so I don't see why there would be memory restrictions at all...

• Can mod_rewrite Conditions/Rules be executed in random order?

  - by Tom

  I have some mod rewrite rules that test for the presence of a file on various NFS mounts and I would like that the tests occur randomly, as a very rudimentary way to distribute load. For example: RewriteEngine on RewriteCond %{REQUEST_URI} ^/(.+)$ RewriteCond /mnt/mount1/%1 -f RewriteRule ^/(.+)$ /mnt/mount1/$1 [L] RewriteCond %{REQUEST_URI} ^/(.+)$ RewriteCond /mnt/mount2/%1 -f RewriteRule ^/(.+)$ /mount2/$1 [L] RewriteCond %{REQUEST_URI} ^/(.+)$ RewriteCond /mnt/mount3/%1 -f RewriteRule ^/(.+)$ /mnt/mount3/$1 [L] RewriteCond %{REQUEST_URI} ^/(.+)$ RewriteCond /mnt/mount4/%1 -f RewriteRule ^/(.+)$ /mnt/mount4/$1 [L] As far as I understand mod_rewrite Apache will look for the file on /mnt/mount1, then mount2, mount3 and so on. Can I randomize this on each request? I understand this is an odd request but I need a creative solution to some unforeseen downtime. On a side note, do I need to redeclare RewriteCond %{REQUEST_URI} ^/(.+)$ each time like I have done? Thanks

• Mouse pointer size inconsistent

  - by charon00

  Since installing Ubuntu 12.04, I've been having a problem with the mouse pointer size. On the desktop, it is quite a bit larger than it should be (24), though the different cursors (editing text, hyperlink hand, etc) are correct. The size changes to the correct size when the pointer is over some application windows (GVim, Netbeans, Firefox), but then changes back once it is moved out of the window. There was a similar question here, but the Xdefaults solution did not work for me, and I didn't want to try the one requiring editing the icon image. In addition, I've tried changing the cursor theme using sudo update-alternatives --config x-cursor-theme as well as using the dconf-editor, but though I can change the theme, the size issue remains. In case it's relevant, I'm running on a dual-screen setup with monitor sizes of 2560x1600 and 1920x1080, using the NVidia video driver. Is there another way to control pointer size, or a setting that might be messing it up? EDIT: These are the values/options I have for update-alternatives and in dconf-editor. I'm now wondering if Netbeans and Firefox are making the mouse pointer smaller than it should be, but I'm not sure how big 24 should be... update-alternatives: Selection Path Priority Status ------------------------------------------------------------ 0 /usr/share/icons/DMZ-White/cursor.theme 90 auto mode 1 /etc/X11/cursors/core.theme 30 manual mode 2 /etc/X11/cursors/handhelds.theme 20 manual mode 3 /etc/X11/cursors/redglass.theme 20 manual mode 4 /etc/X11/cursors/whiteglass.theme 20 manual mode * 5 /usr/share/icons/DMZ-Black/cursor.theme 30 manual mode 6 /usr/share/icons/DMZ-White/cursor.theme 90 manual mode dconf-editor: I can't post the image since I'm a new user but the cursor-size is set to 24 and the cursor-theme is DMZ-Black.

• Cross-platform builds with OGRE3D via CMake. Any tips?

  - by frarees

  I've been trying to compile a simple project for both OSX and Windows platforms, using OGRE3D, but I've got some problems on the way. I'm using CMake to create my platform specific project files (VS solution & Xcode project). Some problems I found are: OGRE3D source is distributed in 2 flavors, Windows sources and UNIX/OSX sources. In OSX, compiling dependencies (freetype, FreeImage and specially OIS) is such a pain. I don't know how to handle precompiled dependencies (they exist for both Win & Mac). May sound like a noob question, but I would appreciate some tips on this. Resources, forum posts, anything. There exists any "cross-platform base project for OGRE3D" on the net? Would be really helpful if someone who already managed to do this can bring some light. Btw, I'm not basing the project on OGRE3D, it's just that is the biggest library I'm probably using, so I depend a lot on it. Thanks in advantage!

• copying corrupted images from a dvd.

  - by Pennf0lio

  Hi, Are there software you know that can copy images from a DVD? now the problem is there images in the DVD that are corrupt that I won't force to copy, If the software can recover the file and copy it that would be cool, If it cannot then skip the file. The dvd is kinda large and I don't want to sit and wait there. I want the DVD do the decision, If it can recover then recover if it cannot, then skip. And do you know other solution copying corrupt files? thanks!

• GLSL custom interpolation filter

  - by Cyan

  I'm currently building a fragment shader which is using several textures to render the final pixel color. The textures are not really textures, they are in fact "input data" to be used in the formula to generate the final color. The problem I've got is that the texture are getting bi-linear-filtered, and therefore the input data as well. This results in many unwanted side-effects, especially when final rendered texture is "zoomed" compared to original resolution. Removing the side effect is a complex task, and only result in "average" rendering. I was thinking : well, all my problems seems to come from the "default" bi-linear filtering on these input data. I can't move to GL_NEAREST either, since it would create "blocky" rendering. So i guess the better way to proceed is to be fully in charge of the interpolation. For this to work, i would need the input data at their "natural" resolution (so that means 4 samples), and a relative position between the sampled points. Is that possible, and if yes, how ? [EDIT] Since i started this question, i found this internet entry, which seems to (mostly) answer my needs. http://www.gamerendering.com/2008/10/05/bilinear-interpolation/ One aspect of the solution worry me though : the dimensions of the texture must be provided in an argument. It seems there is no way to "find this information transparently". Adding an argument into the rendering pipeline is unwelcomed though, since it's not under my responsibility, and translates into adding complexity for others.

• Laptop won't load an OS or even an OS setup.

  - by Talasan Nicholson

  My fiancé's laptop started to crash and would get BSOD errors to the point that she couldn't even boot up because it would either take forever or just crash. So I figured I'd try to reformat, as it's done this before and this was the solution last time. On Windows 7, it will not go passed the "Setup is starting..." screen. On Windows XP, it crashes once the setup is about to start (BSOD). I shut it down and let it sit for 5+ hours, in case it was overheating, but it's doing the same thing anyway. By now, I figure it's something to do with the hardware but I hope not. Any ideas?

• What is the most concise, unambiguous syntax for operator associated methods (for overloading etc.) that doesn't pollute the namespace?

  - by Doug Treadwell

  Python tends to add double underscores before its built-in or overloadable operator methods, like __add(), whereas C++ requires declaring overloaded operators as operator + (Thing& thing) { /* code */ } for example. Personally I like the operator syntax because it seems to be more explicit and keeps these operator overloading methods separated from other methods without introducing weird prefix notation. What are your thoughts? Also, what about the case of built-in methods that are needed for the programming language to work properly? Is name mangling (like adding __ prefix or sys or something) the best solution here? What do you think about having another type of method declaration, like ... "system method" for lack of creativity at the moment. So there would be two kinds of declarations: int method_name() { ... } system int method_name() { ... } ... and the call would need to be different to distinguish between them. obj.method_name(); vs obj:method_name(); perhaps, assuming a language where : can be unambiguously used in this situation. obj.method_name() vs obj.(system method_name)() Sure, the latter is ugly, but the idea is to make the common case simple and system stuff should be kept out of the way. Maybe the Objective-C notation of method calls? [obj method_name]? Are there more alternatives? Please make suggestions.

• Linux/OS X dualboot on a Macbook Pro with RAID

  - by GaretJax

  I'd like to install Gentoo Linux on my Macbook Pro by keeping my current OS X installation. I currently have OS X installed on a RAID 0 on two 160GB Intel SSDs and I'd like to create a new partition for Gentoo alongside OS X without losing the RAID setup but, from what I read on the net, Apple's software RAID is poorly (read "not at all") supported: BootCamp refuses to create a windows partition on a RAID volume rEFIt is not able to boot an OS from a software RAID even Apple's recovery partition for Lion can't be created on a RAID volume Is there a way to dual boot my Macbook while keeping the RAID solution?

• Excel 2010: How to color the area between charts?

  - by Quasdunk

  Hello, I asked this question already on stackoverflow but it hasn't been answered yet. Instead I was advised to try it here, so here I go :) So there's that simple XY-Line-Chart in Excel (2010). It is surrounded by two other graphs which are parallel but offset by the same factor in both the positive and negative direction - something like this: ---------------- (positively offset parallel graph) ---------------- (main graph) ---------------- (negatively offset parallel graph) Now I want to color the space between the main graph and the offset ones, but I just can't seem to find a way! Is it maybe possible with VBA? Or is there maybe a solution for Excel 2007?

• Repository query conditions, dependencies and DRY

  - by vFragosop

  To keep it simple, let's suppose an application which has Accounts and Users. Each account may have any number of users. There's also 3 consumers of UserRepository: An admin interface which may list all users Public front-end which may list all users An account authenticated API which should only list it's own users Assuming UserRepository is something like this: class UsersRepository extends DatabaseAbstraction { private function query() { return $this->database()->select('users.*'); } public function getAll() { return $this->query()->exec(); } // IMPORTANT: // Tons of other methods for searching, filtering, // joining of other tables, ordering and such... } Keeping in mind the comment above, and the necessity to abstract user querying conditions, How should I handle querying of users filtering by account_id? I can picture three possible roads: 1. Should I create an AccountUsersRepository? class AccountUsersRepository extends UserRepository { public function __construct(Account $account) { $this->account = $account; } private function query() { return parent::query() ->where('account_id', '=', $this->account->id); } } This has the advantage of reducing the duplication of UsersRepository methods, but doesn't quite fit into anything I've read about DDD so far (I'm rookie by the way) 2. Should I put it as a method on AccountsRepository? class AccountsRepository extends DatabaseAbstraction { public function getAccountUsers(Account $account) { return $this->database() ->select('users.*') ->where('account_id', '=', $account->id) ->exec(); } } This requires the duplication of all UserRepository methods and may need another UserQuery layer, that implements those querying logic on chainable way. 3. Should I query UserRepository from within my account entity? class Account extends Entity { public function getUsers() { return UserRepository::findByAccountId($this->id); } } This feels more like an aggregate root for me, but introduces dependency of UserRepository on Account entity, which may violate a few principles. 4. Or am I missing the point completely? Maybe there's an even better solution? Footnotes: Besides permissions being a Service concern, in my understanding, they shouldn't implement SQL query but leave that to repositories since those may not even be SQL driven.

• An international mobile app - Should I set up EC2 instances in multiple regions?

  - by ashiina

  I am currently trying to launch an mobile app for users around the world. It is not a spectacular launch which will get millions of users in weeks - just another individual developer releasing an app. I know enough about the techniques of managing timezones, internationalizing string, and what not ( the application layer ). But I cannot find any information on how I should manage my EC2 instances... Should I be setting up EC2 instances in different regions around the world? Is that a must-do, or is it an overkill? I'm aware that it's the ideal solution in terms of performance, but it becomes very tough managing servers in multiple regions. DB issues, AMI management, etc... I'd much rather NOT do so. So I would like to know the general best practice when launching an international app/website. Note: For static contents, I know it's better to use a CDN, so I'm planning on doing so.

I think I know how to do it but I cant confiugre it right. This is what I tried: I turend on ip forwarding (for sure) I set eth1 default gw to the right ip on the wan I tried to set eth0 default gw to the same ip (but i couldnt) What or how can I do this, I was trying with linux route command, but I got stuck.

• Internal speakers do not work

  - by Nikcefo

  I have a new (from scratch, not update) installation of Ubuntu 12.10 on my notebook, Asus A3Ac (It is based on Intel Centrino - Pentium M with full duplex Intel HDA codec). In older versions of Debian-based systems Intel HDA audio didn't work correctly. Alsamixer display wrong outputs and inputs (more than notebook really have). In clean installations internal speakers were playing, but they didn't mute when headphones was plugged in. There was a solution (propably not the best but working) - edit as root /etc/modprobe.d/alsa-base.conf and add a line "options snd-hda-intel model=z71v position_fix=1". After restart it worked correctly (alsamixer displayed correct devices and internal speakers were muted after I plugged in headphones). It was also working in Ubuntu 12.04. In Ubuntu 12.10 I have another problem. The alsamixer in default (don't have to edit alsa-base.conf) display correct outputs and inputs but internal speakers don't working if the headphones isn't plugged in. I have to manually disable "Auto-Mut" option in alsamixer, then the internal spakers works (but of course they don't mute when the headphones are pluged in). Thanks for any idea how to fix it. I'm not sure if it is a bug or it's caused by a "specific hardware". Tomas

• Disable writing RAID degraded mode

  - by jolivier

  I have a RAID5 with 5 disks on my machine and suspect the motherboard chipset to fail at some points and make my raid going in degraded mode. Last time it happened I noticed it on the failure of the 2nd drive connected to the same chipset and lost a lot of data. So I would like to prevent this, and especially I would like to have mdadm disable writes on the raid if one of the disk fails. So that in between I get notified, I recover and can use my system again. Sadly I could not find it in man mdadm so I was wondering if this is possible via a tool or hidden option since for me it looks like a standard feature of a RAID system. If this is not possible I would also be happy with a solution to stop the raid if degraded.

• $DISPLAY dependent gtk themes

  - by Vlad Seghete

  I have a computer at home that I log into remotely. The "monitor" for it is a TV, so I want gtk applications to use a large font and icon theme, which I managed to do by editing the ~/.gtkrc-2.0 file and some other similar stuff. What I want to be able to do is have a separate theme for when I'm logging in remotely. The best way to explain is that I would like my gtk theme choice to be dependent on the X display that the application is started on. For example, if I start something on :0.0 then that is the TV and I want large fonts, but if I start it on localhost:10.0 I want to use a regular size font, because it will get rendered on my laptop screen. The elegant solution would be to have some sort of IF statement in the .gtkrc-2.0 file that checks the $DISPLAY variable and behaves accordingly. The problem is I can't find any documentation on control structures in .gktrc files, or if it's even possible to do that.

• Trouble getting PHP, Apache, and Zend talking to eachother (localhost)

  - by Joel

  Hi guys, I've searched through several other questions, but haven't found my solution. THe main reason is that I'm not even sure if I have all these things properly installed. I have a hosting account, and have always just deployed everything into the internets, but I'm finally trying to figure out how to get my desktop set up right for learning Zend Framework. I have Apache Server 2.2, PHP, And Zend Framework installed. I'm trying to do this tutorial: http://akrabat.com/wp-content/uploads/Getting-Started-with-Zend-Framework.pdf The problem is when I click on the link: http://localhost/zf-tutorial/public I get an Error 404. If I type in http://www.localhost I get "It Works!" in the browser. I'm thinking this means I have Apache installed correctly, but am not pointing correctly to the Zend tutorial? Thanks for any help!

• Raid 5 scsi fault

  - by HaLaBi

  I have no much knowledge about servers and I was looking all day around the internet about finding a solution to my raid 5 problem. All of a sudden two disks failed. The server won't boot (HP Proliant, windows 2003 R2, very old maybe 10 years old). I know that if one disk is faulty then I can add a new disk and rebuild it and things will be fine, the problem is two went faulty :( is this normal? two at the same time? is there any other thing I can do and I am not aware of? other than taking them out and reinserting them back? Windows won't boot. The Array menu shows that disks 0 and 4 are "Missing". Any other tricks or things to do? It is important because for some unknown reason the back up job did not work for a month and I just found out, so I need to make these raid 5 back online again.
