• Printing Booklet Page Size in Adobe Reader 4-in-1

  - by Justin Nathanael Waters

  So I have a 70 page pdf document that I'm trying to condense to a small booklet. I tried creating a formula to manually to perform it but it got ugly fast. 35,36,34,37,17,54,16,55,33,38,32,39,15,56,14,57,31,40,30,41,13,58,12,59 29,42,28,43,11,60,10,61,27,44,26,45,9,62,8,63,25,46,24,47,7,64,6,65 23,48,22,49,5,66,4,67,21,50,20,51,3,68,2,69,19,52,18,53,1,70 Once I print the booklet I should be able to cut the sheets in half and set the bottom half behind the top and staple it for a simple book. Which means Page 1 should have pages 35,36,17,54,34,37,16,55 Page 2 should have pages 33,38,15,56,32,39,14,57 And several pages later Page 9 should have pages 19,52,1,70,18,53 But manually doing this is a headache and it seems like the booklet function should contain functionality that can perform this. I'm using a commercial Konica Minolta C452

• Malicious javascript code in my website

• PHPMyAdmin running very slow over internet but fine locally

  - by columbo

  I connect to PHPMyAdmin remotely on a Centos server using my local PC via Firefox. Usually it's fine but today it's really slow (2 minutes to load a page), sometimes timing out. Other connections to the server are fine. The SSH command line is as fast as ever as is the GNOME dekstop over SSH. In fact on the GNOME desktop I can run PHPMyAdmin locally from its browser and it's as quick as ever (which is a solution to the problem of course). I've checked the various log files and seen nothing unusual, I've logged into the MySQL command line and the database is running fine without any slowing what so ever. So it just seems to be slow when I access PHPMyAdmin on the server from the browser on my remote PC (I've tried IE and Firefox, both are slow). Has anyone experienced this or have any ideas what the issue could be. Connecting via CLI through tunnel works OK - problem is in phpMyAdmin for sure. Cheers

• How to handle knowledge handover effectively?

  - by Zizzencs

  Let's say a large enterprise opens a new office in (insert random location here) and want the new colleges up to speed as fast as possible. Let's also say this enterprise is a very typical one with a complex environment, lots of history and almost full lack of documentation. What's already been decided is that the new colleges will receive howto-style documentation for the most typical tasks and will get seme architecture documentation for some of the more complicated systems. Any ideas about improving this process? And more specifically, how should such a howto document look like to be helpful?

• Hooking up many different external HDs simultaneously

  - by cbizz

  I need a large amount of external storage for an upcoming project. I'm planning on purchasing 10 2TB external drives. I need them all hooked up to a single machine at the same time. What issues will I run into? I plan on using 2 power strips and having them all externally powered from the wall. I will use a USB hub to plug in all the drives. I need drive access time to be as fast as possible. I am using Ubuntu Linux(64 bit). Will I be able to mount 10 drives?

• using one disk as cache for others

  - by HugoRune

  Hi Given a PC with several hard drives: Is it possible to use one fast disk as a giant file cache? I.e. automatically copying frequently accessed data to that one disk, and transparently redirecting reads and writes to that disk, so that other drives would only have be accessed occassionally. (writes would have to be forwarded to the other disks after a while of course) Advantages: the other drives could be powered down most of the time; reducing power, heat, noise speed of the other drives would not matter much. cache disk could be solid state. How can I set such a system up? What OS supports these options? Is this possible at all using Windows or Linux?

• Check the disk for problems on Debian Lenny

  - by Equ

  Hi guys! I just bought a VPS hosting with Debian Lenny (I'm new to all this world). I've managed to install and setup everthing I need pretty well. My testing website works fast as expected most of the time, but sometimes it is really slow (response time is about 5-10 seconds). I checked everything and seems that there are may be some disk issues. How can I check the disk for problems/performance? What else could possible cause such a behaviour? Thank you!

• Putting $$s in the middle of an `equation` environment: why doesn't Latex complain?

  - by Charles Stewart

  I was surprised that the Latex code from a recent question didn't throw up any errors, and even more surprised on further investigation, that Crowley's explanation seems to be true. My intuition about the \begin{equation} ... \end{equation} code is clearly off, what's really going on? Consider this, slightly adapted code: \begin{equation} 1: e^{i\pi}+1=0 $$ 2: B\"ob $$ 3: e=mc^2 \end{equation} This seems to prove that Crowley's explanation of such code, namely that "What that code says to LaTeX is begin equation, end it, begin it again, typeset definition of tangens and end the equation" is right: lines 1&3 can only be typeset in maths mode, line 2 only in text mode. Shouldn't Latex see that the \end{equation} is ending a display math that wasn't started by the \begin{equation}?

• Internet really slow or stops working on my computer but fine on my laptop and ipad

  - by Fr0zen1

  I know you are going to say that this has been answered already, but it hasnt. None of those solutions worked for me. So this is the problem, and it only occurs on my computer, my laptop,ipad and iphone are just fine. When I`m browsing the net, it laods webpages slow(my speed is 30mb down and 3mb up) and when I start downloading with a another application(steam, utorrent), my browser completely stops working, but the application thats downloading(steam, utorrent) continues to download with a fast spead(2-3mb/s) and I do not know why. I have this issue on all browsers. I have tried chrome, internet explorer and firefox. I have restored my windows but still the same issue and I also have kubuntu installed and it also has the same issue. I do not know why. Any help? Thank you

• How do you do incremental search across multiple text files in VIM?

  - by Alex

  Is there a way to have VIM do incremental search on text files? Vim already does incremental search within the currently open file. Examples of programs that demonstrate the type of search I'm trying to accomplish are Notational Velocity for MacOS, Resop for windows or SimpleNote for the web. These apps do an instant or incremental search in the files of a specific directory and make it easy/fast to narrow down the file you are looking for or create a new file. I use both but would rather live in one editor.(that being VIM) Is there some plug in that would do this?

• Generating a beveled edge for a 2D polygon

  - by Metaphile

  I'm trying to programmatically generate beveled edges for geometric polygons. For example, given an array of 4 vertices defining a square, I want to generate something like this. But computing the vertices of the inner shape is baffling me. Simply creating a copy of the original shape and then scaling it down will not produce the desired result most of the time. My algorithm so far involves analyzing adjacent edges (triples of vertices; e.g., the bottom-left, top-left, and top-right vertices of a square). From there, I need to find the angle between them, and then create a vertex somewhere along that angle, depending on how deep I want the bevel to be. And because I don't have much of a math background, that's where I'm stuck. How do I find that center angle? Or is there a much simpler way of attacking this problem?

• Data transfer is extrem slow after partitioning extern usb drive

  - by user125912

  I bought an extern usb 3.0 drive with 500 gb capacity. OS is Windows 7. I use it with an usb 2.0 slot, no prob. Initially I used it without making several partitions and it was fast as hell. Then I had the great idea to make partitions, one for programs, one for data and one for backup. I chose the free EASEUS Partition Master 9.1.1. and ended up with these partitions: F:Apps, primary, NTFS, 100gb H:Data, logic, NTFS, 250gb B:Backup, logic, NTFS, 150gb THE PROBLEM: When I copy files from C: to F: I get a transfer rate of about 100 KB/S ! When I copy files from C: to H: I get a transfer rate of about 4 MB/S ! thats all muuuch to slow, slower then before. What can I do to speed the shit up? Thanks in advance!

• How to set/keep directory permissions?

  - by Dylan

  I'm using CwRsync to connect from my Windows development machine to a linux webserver : rsync -avuz -e ./ssh --exclude=".svn" /cygdrive/c/xampp/htdocs/project123/ [email protected]:/home/user123/public_html This syncs my development project directory nicely and fast to the server. But after doing this, all directory properties are reset to the local user user123 only, so the website is not available anymore. I need to manually reset those properties. Why is this happening, and how to prevent it? PS. coming from a Windows environment I'm having a really hard time understanding rsync. I copied the above command from some examples... just need to get this one small thing working too...

• App to watch installer and roll back host later?

  - by OverTheRainbow

  I'm looking for a Windows application that can watch everything an install programs does to Windows, and can roll it back to what it was like before installing an application. InCtrl5 is useful to know what an installer did, but doesn't provide a way to return the host to its previous state. I'd like to avoid having to restore a host using eg. CloneZilla just for a small application. The goal is to make it fast to test an application in a test lab. Does someone know of an application that can do this? Edit: I wasn't specific enough: I need a way to totally remove an application but keep all other changes I made after installing the application. Edit: After checking a few of them, I settled on Cleanse Uninstaller, which was capable of removing the whole of an application, although it doesn't watch when it's installed.

• Newbie programmer looking for a fun, small project (pref. C++/Python)

  - by Francisco P.

  Hello everyone, I have some experience in Scheme and C++ (read: a semester of each) I know the very basics of Python (used it for physics simulations with the Visual Python module). Can you recommend me some fun and small (i.e. don't take much time) projects on either Python or C++? I have no real preferences, just that it is fun :P Thanks for your time! PS: I've tried projecteuler and python challenge. Euler is good, but more about math than coding, and py challenge just didn't work for me.

• Simple 2 way encryption for C#

  - by Matt Dawdy

  I'm looking for very simple encrypt and decrypt functionality for some data. It's not mission critical. I need something to keep honest people honest, but something a little stronger than ROT13 or Base64. I'd prefer something that is already included in the .Net framework 2.0 so I don't have to worry about any external dependencies. Pre-emptive EDIT: I really don't want to have to mess around with public/private keys, etc. I don't know much about encryption, but I do enough to know that anything I wrote would be less than worthless...in fact, I'd probably screw up the math and make it trivial to crack.

• Can't set element ID in JavaScript, it's always undefined

  - by Dylaan Alith

  Hi, I want to have a function that generates ID's on the fly for a given jquery object, if it doesn't have one already. These ID's should then be used in future requests. I came up with the code below, but it doesn't work. The ID's are never set. The commented out alert statement below always return undefined. I always pass code like $(this) or $(options.el) as a parameter to substitute 'el'. Initially, the elements do not have explicitly ID set in HTML. Any help would be appreciated, here's the code: getElementId: function(el) { if(undefined == el.attr('id')) { el.attr('id',"anim-"+Math.random().toString().substr(2)); } // alert(el.attr('id')); return el.attr('id'); },

• Time of splitting and encoding video with ffmpeg increases exponentially

  - by Rnd_d

  I'm trying to split video by subtitles and encode into .mp4(h.264/aac) using ffmpeg, but it takes so much time! First pieces of video are splited and encoded really fast, but for each iteration time increases, and so 40 min video takes all night or more. Small 3 min video takes max 10 mins. cmd for splitting and encoding: ffmpeg -i filename.avi -ss 00:00:0(time of sub start) -t 0:0:3(time of sub duration) -acodec libfaac -vcodec libx264 -bf 0 -f mp4 filename.mp4 ffmpeg version N-34849-g07c7ffc (last, i think) How I can make it faster? Are there, maybe, some magic arguments for ffmpeg or some hacks?

• What we call this kind of chaining in C#

  - by Thinking

  Can you please tell me what kind of construct in C# is this. Code Golf: Numeric equivalent of an Excel column name C.WriteLine(C.ReadLine() .Reverse() .Select((c, i) => (c - 64) * System.Math.Pow(26, i)) .Sum()); Though I am new to C# (only two months exp so far), but since the time I have joined a C# team, I have never seen this kind of chaining. It really attracted me and I want to learn more about it. Please give some insight about this.

• Moving files with batch files from one pc to a server, to a another pc - worried about disk corruption

  - by AnchientAnt

  I use scheduled tasks that calls a batch file, that calls more batch files to move about three files from a pc, to a server, then to multiple other pcs. It all happens very quickly, as they are small files. Are there any pitfalls for how fast these transfers happen? I'm just mildly concerned about causing some disk corruption somehow. I use logic like 1. Call MapToPc if files exist then move file to folder on server. Disconnect 2. Call SendtoPCs If files exist (the files just moved to the server) then MapToPCs Move all files Disconnect All of this happens in about 2 secs or less. edit: this on windows 7, server 2003, xp respectively

• A 4-byte Unsigned Int for Sql Server 2008?

  - by Jeff Meatball Yang

  I understand there are multiple questions about this on SO, but I have yet to find a definitive answer of "yes, here's how..." So here it is again: What are the possible ways to store an unsigned integer value (32-bit value or 32-bit bitmap) into a 4-byte field in SQL Server? Here are ideas I have seen: 1) Use a -1*2^31 offset for all values Disadvantages: need to perform math on the values before reading/writing/aggregating. 2) Use 4 tinyint fields Disadvantages: need to concatenate values to perform any operations 3) Use binary(4) Disadvantages: actually uses 4 + 2 bytes of space

• Need an idiot-proof picture resizing program for Windblows.

  - by marcusw

  My friend needs to resize some pictures as part of a web publishing job, but he is rather clueless when it comes to computers. I am in charge of teaching him how to do this, but only have Linux (albeit with Wine installed) at my disposal for testing. Could you guys recommend a fast, easy, batch-capable, and hopefully open-source program that will resize pictures to the resolution he wants? It doesn't have to be anything fancy, but it needs to be quick and easy to use. Thanks!
