  • After one has made many grid based puzzles how does one make then into a PDF ready for printing

    - by alan ross
    After one has generated many grid based puzzles like sudoku, kakuro or even plain crosswords and now one has to print them in a book. How does one make a pdf (book file) from them automatically. To explain the question better. One has the puzzle ready in computer format like ..35.6.89 for all nine rows. The dot being the empty cell. How does one convert then to a picture on a PDF page complete with box, automatically without doing them individually and then print a book from the pdf file. As can be seen there are other things also printed on the page all this is done automatically.

  • Tracking a single page on another domain in Google Analytics

    - by Ross
    I have access to edit a 'mini-site' hosted on our organisation's parent site. I'd like to track this page using Google Analytics, however I don't have access to the front page so I can't verify this as my domain. Using the tracking code for our main site works, however I don't want this data to be confused with similarly named pages on our site (for example, our mini-site is at /radio, and if we had a /radio at our main site this would be counted as the same). Has anyone been in this situation before? I'd like to just redirect visitors to our mini-site to our main site, seeing as it ranks higher in Google, but I've been told to maintain a separate site with our main features.

  • Are there architecture smells?

    - by C. Ross
    There are tons of resources on the web referring to and listing code smells. However, I've never seen information on architectural smells. Is this defined somewhere, and is there a list available? Has any formal research been done into architecture defects, and their impact on project speed, defects, and the like? Edit: I wasn't really looking for a list in the answers, but documentation (on the web or in a book) about architecture smells.

  • What's the risk of upgrading over SSH?

    - by C. Ross
    When I run sudo do-release-upgrade over ssh, I get the following message. This session appears to be running under ssh. It is not recommended to perform a upgrade over ssh currently because in case of failure it is harder to recover. If you continue, an additional ssh daemon will be started at port '9004'. Do you want to continue? What is the real risk of upgrading over ssh? How does the additional ssh daemon help mitigate this?

  • What should I use for a package name if I don't have a domain? [closed]

    - by C. Ross
    Possible Duplicate: What is the point of Java’s package naming convention? What package name to choose for a small, open-source Java project? I write Java (and derivative languages with package names) for personal use, but I don't have a personal domain name, so the standard packaging naming convention doesn't hold. Since the same convention is used in Maven group-id's, the problem is the same there. What should I use for the root of my package name?

  • Tactics for using PHP in a high-load site

    - by Ross
    Before you answer this I have never developed anything popular enough to attain high server loads. Treat me as (sigh) an alien that has just landed on the planet, albeit one that knows PHP and a few optimisation techniques. I'm developing a tool in PHP that could attain quite a lot of users, if it works out right. However while I'm fully capable of developing the program I'm pretty much clueless when it comes to making something that can deal with huge traffic. So here's a few questions on it (feel free to turn this question into a resource thread as well). Databases At the moment I plan to use the MySQLi features in PHP5. However how should I setup the databases in relation to users and content? Do I actually need multiple databases? At the moment everything's jumbled into one database - although I've been considering spreading user data to one, actual content to another and finally core site content (template masters etc.) to another. My reasoning behind this is that sending queries to different databases will ease up the load on them as one database = 3 load sources. Also would this still be effective if they were all on the same server? Caching I have a template system that is used to build the pages and swap out variables. Master templates are stored in the database and each time a template is called it's cached copy (a html document) is called. At the moment I have two types of variable in these templates - a static var and a dynamic var. Static vars are usually things like page names, the name of the site - things that don't change often; dynamic vars are things that change on each page load. My question on this: Say I have comments on different articles. Which is a better solution: store the simple comment template and render comments (from a DB call) each time the page is loaded or store a cached copy of the comments page as a html page - each time a comment is added/edited/deleted the page is recached. Finally Does anyone have any tips/pointers for running a high load site on PHP. I'm pretty sure it's a workable language to use - Facebook and Yahoo! give it great precedence - but are there any experiences I should watch out for? Thanks, Ross

  • Java app makes screen display unresponsive after 10 minutes of user idle time

    - by Ross
    I've written a Java app that allows users to script mouse/keyboard input (JMacro, link not important, only for the curious). I personally use the application to automate character actions in an online game overnight while I sleep. Unfortunately, I keep coming back to the computer in the morning to find it unresponsive. Upon further testing, I'm finding that my application causes the computer to become unresponsive after about 10 minutes of user idle time (even if the application itself it simulating user activity). I can't seem to pin-point the issue, so I'm hoping somebody else might have a suggestion of where to look or what might be causing the issue. The relevant symptoms and characteristics: Unresponsiveness occurs after user is idle for 10 minutes User can still move the mouse pointer around the screen Everything but the mouse appears frozen... mouse clicks have no effect and no applications update their displays, including the Windows 7 desktop I left the task manager up along the with the app overnight so I could see the last task manager image before the screen freezes... the Java app is at normal CPU/Memory usage and total CPU usage is only ~1% After moving the mouse (in other words, the user comes back from being idle), the screen image starts updating again within 30 minutes (this is very hit and miss... sometimes 10 minutes, sometimes no results after two hours) User can CTRL-ALT-DEL to get to Windows 7's CTRL-ALT-DEL screen (after a 30 second pause). User is still able to move mouse pointer, but clicking any of the button options causes the screen to appear to freeze again On some very rare occasions, the system never freezes, and I come back to it in the morning with full responsiveness The Java app automatically stops input scripting in the middle of the night, so Windows 7 detects "real" idleness and turns the monitors into Standby mode... which they successfully come out of upon manually moving the mouse in the morning when I wake up, even though the desktop display still appears frozen Given the symptoms and characteristics of the issue, it's as if the Java app is causing the desktop display of the logged in user to stop updating, including any running applications. Programming concepts and Java packages used: Multi-threading Standard out and err are rerouted to a javax.swing.JTextArea The application uses a Swing GUI awt.Robot (very heavily used) awt.PointerInfo awt.MouseInfo System Specs: Windows 7 Professional Java 1.6.0 u17 In conclusion, I should stress that I'm not looking for any specific solutions, as I'm not asking a very specific question. I'm just wondering if anybody has run into a similar problem when using the Java libraries that I'm using. I would also gladly appreciate any suggestions for things to try to attempt to further pinpoint what is causing my problem. Thanks! Ross PS, I'll post an update/answer if I manage to stumble across anything else while I continue to debug this.

  • Cannot import SQLite with Python 2.6

  • Du tells me it can't find the current directory?

    - by C. Ross
    I'm on AIX, and in some directories I can't use the du command. I get the follow error message: du: 0653-175 Cannot find the current directory. Obviously the current directory exists, and I have permissions to it. I can list the directory and create files in it, both before and after I ran du. What could possibly be wrong here? The du command works just fine in my home directory. A quick google search turns up a bunch of forum posts of the same problem, but no clear answers.

  • dedicated server - cgi-sys/defaultwebpage.cgi redirect when accessing via server IP

    - by Ross
    This isn't so much of a problem, but would like to know why this happens. we have a dedicated server running WHM. If I access the server via its IP address directly I am automatically redirected to http://xx.xxx.xx.xxx/cgi-sys/defaultwebpage.cgi I know how to edit this page (this isnt the problem) I'm just curious why I get redirected to this .cgi page, rather than simply remain @ xx.xxx.xx.xxx/ and view my default "landing page", if you like. What setting could I change so that if anyone visits my server IP, they do not get redirected to xx.xxx.xx.xxx/cgi-sys/defaultwebpage.cgi For instance if you visit 173.194.37.104 (google), you view the google home page, but URL remains the same. Hope this makes sense. thanks

  • Clients not updating with approved updates from WSUS

    - by Ross
    Hi All, I've been a bit behind in my windows XP updates recently, and I have about 18 or so I need to roll out to all our users, according to WSUS. I'm trying it on a couple of test PCs, and so far i've had no luck. On each one, one update would install (and need a reboot), and nothing else since.

For example: spider31.yandex.ru - 77.88.26.27 spider79.yandex.ru - 95.108.155.251 etc.. I can put some deny in robots.txt but not sure if it respect this. I am thinking of blocking a list of IP ranges. Can somebody suggest some general solution.

  • Lotus Notes 8.5.3 "Unable To Invoke Program"

    - by Ross Doughty
    Just got a little issue with some of my users today, when trying to open an email attachment in Lotus Notes, they get the error Unable To Invoke Program. Now, they can always just save the attachment and then open it through windows explorer, which is fine, but I would rather get a proper solution for this. Knowing almost nothing about Lotus Notes does not help me I know but I think it may have something to do with the default file association, however my colleague tells me that Notes uses the windows file associations, which are working. Any ideas anyone?

  • Set JENKINS_HOME in Tomcat7?

    - by C. Ross
    I'm trying to set up Jenkins in Tomcat7 on Ubuntu. I installed Tomcat7 and deployed jenkins.war, and I now see the Jenkins home page at http://myhost:8080/jenkins, but it's attempting to create the Jenkins directory at /usr/share/tomcat7/.jenkins, which it can't for security reasons. I've already created /srv/jenkins and given the tomcat7 group permissions, and want to set JENKINS_HOME to that path. I've tried adding it to the tomcat configuration in /etc/tomcat7/server.xml: <GlobalNamingResources> <Environment name="JENKINS_HOME" value="/srv/jenkins" type="java.lang.String" override="false"/> <!-- Default settings --> And I've also tried adding it to the automatically created context file in ROOT/META-INF/context.xml (there is no $CATALINA_HOME/conf as far as I can tell). <Context path="/" antiResourceLocking="false" > <Environment name="JENKINS_HOME" value="/srv/jenkins/" type="java.lang.String"/> </Context> But even after restarting tomcat7 I still get the same result (trying to use /usr/share/tomcat7/.jenkins). Where do I need to set the environment variable for JENKINS_HOME in Tomcat7?

  • Error message: do not have authority to access this function

    - by Ross
    Hi. I just reinstalled Windows on my computer after getting a virus. I worked with it for a while and everything worked as it should. I then used a backup of the computer that I had made a week or so earlier and copied the backup over my user folder. (That is, I took the folder named "Joe" from the backup drive and copied-replaced the whole thing over the folder named "Joe" on the new Windows install.) To do this I had to work from an Ubuntu live CD because some of the files were in use. Now the problem: After I did this copying my computer says that I have no authority. Anytime I try to access anything that is part of the operating system (Explorer, Personalize, Control Panel, etc) I get an error message that says I don't have the authority to do this. I am able to access things that aren't part of the OS: Chrome, Firefox, my accounting software, Rockbox, but nothing that is part of the OS. I only copied over the User file, so I didn't mess with the registry or anything, so I have no idea why this should be. Does anyone out in cyberspace have any idea? Thank you.

I'm also getting this error repeatedly in the logs 06/06/2010 08:26:56.563783 zmwatch[28234].INF [Restarting capture daemon for main_room, shared memory not valid] 06/06/2010 08:26:56.812964 zmwatch[28234].INF ['zmc -d /dev/video0' starting at 10/06/06 08:26:56, pid = 29214] 06/06/2010 08:27:06.814486 zmwatch[28234].INF [Restarting capture daemon for main_room, shared memory not valid] 06/06/2010 08:27:07.054854 zmwatch[28234].INF ['zmc -d /dev/video0' starting at 10/06/06 08:27:07, pid = 29219] I've already tried following the instructions in the FAQ for increasing shared memory, but that doesn't seem to work. What do I need to do to get this working?

  • How do I silence strace's message "[ Process PID=15733 runs in 64 bit mode. ]" ?

    - by Ross Rogers
    I'm using memoize.py, but strace keeps injecting the following into the program output each time a process is executed: [ Process PID=15733 runs in 64 bit mode. ] or [ Process PID=16503 runs in 32 bit mode. ] How can I silence strace such that it doesn't inject these statements into the log file? At the very least, I'd like these statements to only go into the output file that memoize.py is instructing strace to use. It's already telling strace to put its output into a specific file ithrough arguments -o /tmp/OUTFILE. Note that strace is being called with the -f parameter to follow child processes.
