• How can I programmatically renumber pages in a PDF?

  - by Andrew

  As a graduate student, I come across PDFs of articles and book chapters on a daily basis. Sometimes these PDFs are paginated correctly internally (that is, if an article starts on page 67, the PDF starts on page 67 as well; not on page 1). When they aren't, I have to open the file in Acrobat and renumber the pages in the "Page Thumbnails" panel. I would love to be able to automate this whole process with a script (bash, Python, AppleScript, whatever) that lets me pass the first actual page number... something like fixpagination example.pdf 67. However, I cannot find any terminal-based program that can re-paginate PDFs. Neither pdftk nor PyPDF seem to be able to deal with pagination. Are there any scriptable programs that can internally re-paginate PDF files?

• Is there way to enable 4 GB RAM in 32-bit Windows OS?

  - by Wahid Bitar

  I upgraded my PC to 4 GB RAM and I get only 3 GB. Windows 7 32-Bit consider that I've 4 GB RAM but didn't use more than 3 GB. Someone told me that MS Windows 32-bit doesn't support RAM larger than 3 GB. So please is there any way to make my OS "Windows 7 32-Bit" support more than 3 GB RAM ? *`Note: I can't move to 64-bit because I've many program doesn't work with a 64-bit OS. Edit:: I tried what Mr. Wonsungi advised me but whenever I check this option: Enable support for 4 GB of RAM I get the following error: 'Cannot access to the registry key HKEY_CLASSES_ROOT\CLSID\{E88DCCE0-11d1-A9F0-00AA0060FA31}.' There is no "CLSID" in my registry, I don't know why!.

• How do I configure hardware raid in a Poweredge 2850?

  - by Eric Fossum

  I just bought a Dell Poweredge 2850 from Craigslist and for the most part I'm happy with it's $300 price-tag, but I cannot figure out where to configure the embedded hardware raid... I've seen online you should hit <CTRL-M>, but while booting my box never says that. I have <CTRL-A> (I think) for an LSI Logic config, but that seems to just program SCSI and verify drives on my SCSI-A and SCSI-B. Anyone have a clue where this RAID config is?

• Poor CPU usage under Ubuntu

  - by remek

  Hello, I just upgraded from Ubuntu 9.10 to Ubuntu 10.04 and I am now experiencing a strange problem. My computer has a quad-core processor, and when I am running several processes simultaneously, none of the cores is fully used. Before the upgrade, when I was running 4 processes, each of them was using 100% CPU (I could see that with the 'top' command). But now, CPU usage oscillates and is always pretty low. Has anybody an idea about this problem? Is it due to Ubuntu or to the program I am running? Thank you very much in advance for your help! Best, remek

• What tools and knowledge do I need to create an application which generates bespoke automated e-mails? [on hold]

  - by Seraphina

  I'd like some suggestions as to how to best go about creating an application which can generate bespoke automated e-mails- i.e. send a personalized reply to a particular individual, interpreting the context of the message as intelligently as possible... (This is perhaps too big a question to be under one title?) What would be a good starting point? What concepts do I need to know? I'd imagine that the program needs to be able trawl through e-mails as and when they come in, and search for keywords in e-mail content, in order to write an appropriate reply. So there needs to be some form of automated response embedded in the code. Machine learning and databases come to mind here, as I'm aware that google incorporates machine learning already in gmail etc. It is quite tricky to google the above topic, and find the perfect tutorial. But there are some interesting articles and papers out there: Machine Learning in Automated Text Categorization (2002) by Fabrizio Sebastiani , Consiglio Nazionale Delle Ricerche However, this is not exactly a quick start guide. I intend to add to this question, and no doubt other questions will spark off this one. I look forward to suggestions.

• No colors when running native windows shell application from mintty

  - by Pete

  Hi. I have installed cygwin (i'm not very experienced with it), and try to run a native windows shell application from it, (msbuild.exe which is the build tool for the .NET framework, to be exact). When I run the application from the normal cygwin bash shell, the output of the application appear as it should with the text colors that I would normally see in the windows command line. But when I execute the program from a mintty terminal, there is no coloring of the output, all text is in the default foreground color. I'm puzzled, because I would have expected the color coding to be the standard ANSI color code escape characters... Can this be fixed?

• Rendering multiple squares fast?

  - by Sam

  so I'm doing my first steps with openGL development on android and I'm kinda stuck at some serious performance issues... What I'm trying to do is render a whole grid of single colored squares on to the screen and I'm getting framerates of ~7FPS. The squares are 9px in size right now with one pixel border in between, so I get a few thousand of them. I have a class "Square" and the Renderer iterates over all Squares every frame and calls the draw() method of each (just the iteration is fast enough, with no openGL code the whole thing runs smootlhy at 60FPS). Right now the draw() method looks like this: // Prepare the square coordinate data GLES20.glVertexAttribPointer(mPositionHandle, COORDS_PER_VERTEX, GLES20.GL_FLOAT, false, vertexStride, vertexBuffer); // Set color for drawing the square GLES20.glUniform4fv(mColorHandle, 1, color, 0); // Draw the square GLES20.glDrawElements(GLES20.GL_TRIANGLES, drawOrder.length, GLES20.GL_UNSIGNED_SHORT, drawListBuffer); So its actually only 3 openGL calls. Everything else (loading shaders, filling buffers, getting appropriate handles, etc.) is done in the Constructor and things like the Program and the handles are also static attributes. What am I missing here, why is it rendering so slow? I've also tried loading the buffer data into VBOs, but this is actually slower... Maybe I did something wrong though. Any help greatly appreciated! :)

• Changing wallpaper depending on time of day via script or batch file?

  - by Patrick

  I want to have 2 different wallpapers that change according to time of day (6 and 22 hours respectively) and only want to display the night one after 22 hours and the day one only after 6 hours and until 22 hours. I didn't find a program that can do this after a standby, so I thought it should be easy to realize with the task scheduler running a script. Now the question is not only how to realize such a script, but also if the script should include the time checking or the task scheduler. I'm not sure what would work better with long times of the PC being in standby. I tried a few scripts already from similar questions and hoped I could modify to them to my needs, but they didn't work at all. Anyone able to help me? TIA.

• Can I remove a RAR file's (known) password without recompressing the archive?

  - by Abluescarab

  Long title. Anyway, I haven't been able to find an answer to this question. I know the password to the RAR file, I locked it myself, but now all I want to do is remove the password because it's too much of a pain in the butt to type it in every time. Is there a way to do this in WinRAR or an equivalent program? The only thing I knew to do was to extract it, then create a new RAR without the password. It's not a life-or-death issue, but it would be nice to know. Thanks for your time! EDIT: I just saw a bunch of related questions that appear to ask the same thing. The only solution I saw was using a DOS command to yadda yadda yadda. Here it is: How to remove password protection from compressed files Is there an easier way? Thanks again!

• Extract Certs from Apache

  - by user271619

  Recently I've had to uninstall a single Self-Signed SSL Certificate from one of my Apache boxes, specifically for an outside party. That's not really a problem for me, since it was easy. What confuses me is how they knew I had a self-signed certificate. The domain I provided them was not related to the domain with the self-signed certificate. Does this mean Apache publicizes the Virtual hosts in the httpd.conf file? I asked the outside party what software they used to extract information from my server, and they provided this GitHub link: https://gist.github.com/4ndrej/4547029 I figured I'd ask the community first, before I attempt installing the Java program.

• Is there a way to reliably backup and restore a complex network configuration on Windows XP?

  - by djangofan

  I have some Windows XP laptops (10+) that host a ad-hoc WIFI network connection to wireless PDA devices. The laptop itself is connected via a 3rd party VPN radio network. The radio network itself seems to be reliable. If one small thing goes wrong with the network configuration then the PDA loses connectivity and so I need a way to backup a networking config , either via a script or a 3rd party program, so that I can restore a working network configuration if something goes wrong. Is this possible? Does anyone have any ideas?

• Maintaining C/C++/Java skills as a web developer

  - by wwwuser

  When I was in college I learned how to program in C, C++, and Java. Currently, I'm a web developer using front end and back end technologies (HTML/CSS/JS, PHP, MYSQL). While the sorting algorithms and OOP concepts that I learned in college can be applied to web development, I'm looking for ways to keep up my knowledge of all languages. I enjoy programming in C-Style (C/C++/Java) languages and front-end/back-end technologies. Unfortunately, there aren't many options to use C-style languages to build websites. However, I would like to keep up my knowledge and skills in the languages I learned in college as I know they will continue to help me with my growth. What resources are available to keep challenging myself in C-style languages that are relevant to web development? Would contract work for C-style languages be beneficial? Are there sites that offer algorithm challenges? Any help is appreciated. I'm also interested in how others that have asked themselves this have solved this problem.

  - by Bec

  i think that's what i need? i'm not sure i'm trying to run a command line program (BLAST, from NCBI) but it won't recognise the commands (blastall, formatdb, etc.) so i think i need to add the folder the bin is in to the path environment variable? i think that's what i need to do? i think that's what it's called? I think i've been shown this a few times, but i don't need to do it often, so i keep forgetting.

• Can a GPO Startup Script starts a background process and exit immediately?

  - by pepoluan

  I have Googled, and not yet found an answer. Scenario: One of my GPOs have a Startup Script that takes a long time to finish. For some reasons, we have to run the scripts synchronously. Naturally, this causes slow startup time (sometimes as long as 15 minutes!) before the Logon screen appears. After profiling and analyzing the perpetrator script, I conclusively determined that the step where it's taking a long time to finish will not affect the result of the succesive GPOs. In other words, that particular step (and all steps afterwards) can run in the background. My Question: Is it possible for the Startup Script to just 'trigger' another script/program that will run to completion even when the Startup Script exits? That is, the "child processes" of the Startup Script continues to live even when the Startup Script's process ends? Additional Info: The Domain Controllers are 2008 and 2008 R2's. The workstations are Windows XP.

• Cannot access windows share

  - by Wrigley

  I have an accounting program specifically tailored to the IT industry, its called Fincon (exe based). It basically works on a client to server directory base system. the server is currently running on a windows 7 machine with a NTFS partition. I have installed Wine. Have the shared Windows directory mounted with what I assume is the correct command for such being (mount -tsmbfs //servername/sharedir /mnt/fincon -0 usename=username,password=password). I can see the shared dir although it does take a bit long to access it on the Ubuntu machine via the mapped directory but instant via normal network browsing. I have also set up the mapped directory to my D: drive in Wine and have pointed the fincon.ini to read server field from D: directly. Here's my issue, it seems that for some odd reason I cant write to the mapped directory from Ubuntu, yet I can with my Windows machines, the permissions are set correct on the Windows 7 share and I really dunno what I'm missing. I'm quite a Linux noob just switched yesterday. Thanks guys for any help in this would be quite appreciated. As I'm pulling out my hair here and really want to migrate my work PCs to a Linux OS as it just gives less issues than Windows does ever.

• How can I fix my C++ compiler as it isn't loaded by default?

  - by GNR

  Recently I had installed the Ubuntu flavour of the Linux operating system. I had opened a terminal and just wrote a sample C program to check if it is compiling. When I saved the sample file and compiled with cc a.c, errors comes that the standard library is not loaded (i.e stdio.h). When I went to help pages, it says that the C or C++ compiler doesnt gets loaded by default and we should do it ourselves. So can anyone help me out to fix this problem, i.e to load the C/C++ compiler.

• Random touchpad and keyboard freezes on new 10.10 installation

  - by ancaleth

  My touchpad and keyboard freeze up on my newly installed Ubuntu 10.10. I was using Ubuntu 10.4 via wubi before on this Laptop where this problem never occurred. (I did not migrate wubi or upgrade to 10.10, it's a fresh start. 64-bit on Dell Studio, plenty of RAM, plenty of free space on partition etc.) I can't say there is a pattern yet, once it happened during the download of packages with the Update Manager, once it was just using Firefox, no other program running. I was forced to shut down manually. In between these crashes the laptop was booted once, updates were installed etc., firefox was used and there weren't any problems. Both crashes should be in the attached kern.log and I noticed there were some error problems before the last crash (at the end, obviously). It seems the wireless was experiencing problems. This wasn't noticed on the user end, since the touchpad + keyboard were already frozen. kern.log: http://paste.ubuntu.com/552617/ How can the freezes be fixed?

• What naming pattern can I use for sequential file naming (photos) when only their relative sequence is known?

  - by Juhele

  I got some old scanned photos and I want to put them in correct order. Unfortunately, I have no possibility to find out the exact order, only relative one like: "hm, this photo was surely taken after this one" and organize them step-by-step by manually changing numbering again and again. Is there any program (best free or opensource), where could I interactively put the photo in correct order straightaway (maybe by changing the order by dragging with mouse) and finally apply some file renaming to keep the file order? thank you in advance PS: running Windows (XP and 7), but if you know something for linux, let me kno too, please

• Can the "Documents" standard folder be rescued and how?

  - by romkyns

  Anyone who likes their Documents folder to contain only things they place there knows that the standard Documents folder is completely unsuitable for this task. Every program seems to want to put its settings, data, or something equally irrelevant into the Documents folder, despite the fact that there are folders specifically for this job. So that this doesn't sound empty, take my personal "Documents" folder as an example. I don't ever use it, in that I never, under any circumstances, save anything into this folder myself. And yet, it contains 46 folders and 3 files at the top level, for a total of 800 files in 500 folders. That's 190 MB of "documents" I didn't create. Obviously any actual documents would immediately get lost in this mess. My question is: can anything be done to improve the situation sufficiently to make "Documents" useful again, say over the next 5 years? Can programmers be somehow educated en-masse not to use it as a dumping ground? Could the OS start reporting some "fake" location hidden under AppData through the existing APIs, while only allowing Explorer and the various Open/Save dialogs to know where the "real" Documents folder resides? Or are any attempts completely futile or even unnecessary?

• Need to automount dvd or cdrom at fixed mount point in Ubuntu 11.04

  - by Lindsay Haisley

  Ubuntu 11.04, by default, automounts a cdrom or dvd at /media/<vol_name>. I need to make the automounting system use a fixed name instead of the volume name for all CDs or DVDs inserted into this particular drive, e.g. "/media/op-drive0". A bit of searching turns up pretty much the same solution I used, successfully, on an older, gentoo box, which is to create an fdi file for hal, along the lines of the instructions at https://bbs.archlinux.org/viewtopic.php?id=91450. This doesn't seem to work on this box. Other sources say to use the gnome-mount utility to set the mounting properties. Ubuntu 11.04 doesn't know about the gnome-mount program. Any ideas?

• Windows terminating system processes

  - by jemper

  To be sure nobody will answer me with advice on not trying to terminate critical (system) processes - I'm relatively experienced in programming and Windows in general - I'd know what I'm doing so far. So there are these processes that can't be terminated with taskkill - system processes in general. But there also is, for example my Anti Virus program that makes itself "unterminateable". How can I access and mainly terminate system processes under windows? (kill.exe by Microsoft doesn't work) How do processes like anti-virus programs protect themselves? How can you turn them off again, then?

• Windows 7 is blocking ports

  - by Caleb1994

  I am trying to open port 80 and 3690 for HTTP and svnserve respectively. I have Windows Firewall off, and have tried temporarily disabling Mcafee VirusScan Enterprise, to no avail. According to http://www.yougetsignal.com/tools/open-ports/, both ports 80 and 3690 are still blocked. I can't think of what would be blocking them if Windows Firewall and my antivirus are disabled. Here is the output of netsh firewall show state Firewall status: ------------------------------------------------------------------- Profile = Standard Operational mode = Disable Exception mode = Enable Multicast/broadcast response mode = Enable Notification mode = Enable Group policy version = Windows Firewall Remote admin mode = Disable Ports currently open on all network interfaces: Port Protocol Version Program ------------------------------------------------------------------- 3690 TCP Any (null) 22 TCP Any (null) 80 TCP Any (null) 1900 UDP Any (null) 2869 TCP Any (null) Any help? I'm not sure what each item on the list of enabled/disabled items is, but "Operational Mode" is disabled, so I assume that one refers to me disabling Windows Firewall. I know that since Windows Firewall is off, this output might not be useful, but I figured I'd include it just in case, haha.
