  • Taking a look at the Mindscape Phone Elements for WP7.

    - by mbcrump
    I recently heard that Mindscape HQ had released the Windows Phone 7 Controls and had to take a look at them. 100 FREE LICENSE GIVEAWAY! Before we get to the screenshots, you will be pleased to learn that my usergroup called “Allaboutxaml” has partnered with Mindscape HQ and are giving away 100 license. You can check out the site here to get your free controls. But please hurry as after the 100 are gone then I will not have any more to give away! A few links to read first: The official blog post from Mindscape HQ detailing the release. They also have the links to download the trial and get started. The phone elements official forum! So, let’s get started. After you download the controls go ahead and double click the .exe to get started installing them. After everything is installed then you will have the following program group. I’d recommend clicking on the Phone Elements Directory to get started: Let’s go over each element: Bin – Just the .DLL that’s required to use Mindscape HQ WP7 Controls in your project. Documentation – a .CHM File that will show you how to get your project up and running quickly. Resources – Just a few image files Samples – This is a full WP7 project that details every controls. The thing that I was most interested in was how the controls look and is it easy to use. I always believed if your paying for controls then you should hold my hand through using them. You will be pleased to know that Mindscape made it very easy to use. First, the WP7 project in the “Samples” folder just works. Double click on the solution file and you are in an emulator looking at the controls. Since you have the source code for every control, it’s a matter of copying/pasting the code in your project to get it to work. What I did, was play with the controls in the emulator until I found one I could use. Then I looked at the Visual Studio solution and found the Page that contained the control. Mindscape makes this very easy to do with their layout: So, the one that I was interested in was the Looping List Box.  Here is a demo of it: I wanted to see how they were populating the numbers 1-100 so I found the code behind and noticed it was just this one line. LoopingListBox1.DataSource = new NumericDataSource() { MinValue = 1, MaxValue = 100 }; In case you are wondering, the NumericDataSource was created by MindScape and you can view the Declaration to find out more about it:   So, the controls are pretty much that easy to use. Play with the emulator and find the control you want to use. Find the XAML file in the Sample Solution and copy/paste the code. Let’s go ahead and take a look at the controls available: They also have a great variety of Charting controls: Overall it’s a nice set of WP7 controls. Feel free to leave a comment below on anything you would like to see and I will make sure that Mindscape HQ get the message. Don’t forget if you are the first 100 people reading this article then you will get a free license.  Subscribe to my feed CodeProject

  • How to be Agile when new work keeps affecting completed work?

    - by jdln
    The project I'm working on is to re-skin an existing website. The functionally will stay the same, its just the styles that are changing. The HTML is not changing, I'm only modifying the CSS files. The site is pretty complex. There are dozens of pages. Users can be logged in and have a number of different roles. Depending on their role the content of the page and what pages they are allowed to see varys. We're using GIT and Github. I'm trying to write CSS that works as components. So when the same form elements, headings, etc appear on multiple pages they are already styled and are consistent. Most of time this is working well. Sadly the format and class names in the HTML are at times messy and unpredictable. When I fix something on one page it can break another. The job is also harder as no one knows exactly all the variations that are possible due to the user roles. As such I'm continuously finding new variations as I go along. I'm making headway by putting a lot of comments in my CSS. If I need to remove a CSS rule Ill comment it out so I can still see it with the chrome dev tools, and ill put a comment in the CSS saying why I removed it and for what page this was done. This means that if on another page I'm about to add add the rule to fix a different problem, there is more of a chance I will see how this would break the first page. This allows me to either find a different solution that will work for both pages, or I can make the override page specific. This has been working quite well for me. If I had complete free reign and the only deadline was to finish the project by the end then this method would be fine. However my manager is trying to mitigate risk by breaking the work into areas to be completed per sprint. This is counter to how I have been approaching things as something like my typography styles will affect all other pages on the site. The other issue is that the different stakeholders want to sign off each section as I go along. However once I've finished a section it may change if I change CSS that affects it and also affects a new section I'm working on. I've asked that the stakeholders have a quick unofficial sign off in stages (eg per sprint), and have the final official sign off at the end of the project, but this is being met with resistance. I do understand why it would be higher risk to do this, but the only way to guarantee that a signed off section will not change is to make ALL future changes page specific. In addition to this I'm being told that all work that I push to the Git repo should be ready to go live, and as such should not contain any code comments. This is risky for me as I wont know until I've finished the site if I will ever benefit from these comments or not. Has anyone else been in a similar situation and managed to find a compromise that worked for my development approach and also the desires of management and stakeholders to have a more Agile approach? A more Agile workflow works great when you can break the work into components and know that once something is done it wont be affected by future work. However the nature of this project makes this hard to achieve.

  • My Favorite Free Windows Phone Twitter App

    - by Tim Murphy
    Windows Phone 7 has been out for about two years now.  In that time I have switched back and forth with different free Twitter apps.  Mostly the has been because someone has mentioned one or another that they like.  I figured I would give a quick run down of what I felt were the pros and cons of each.  These are only the ones that I have used and your mileage may vary.  So here we go. WP7 Built-In Twitter Functionality While it is great that Microsoft put this functionality in, it is extremely limited in usefulness.  Some apps leverage it to allow you to share pictures or information they contain.  In all though, I don’t use it unless it is the quickest way to get something out. Official Twitter App The official Twitter app isn’t a very big step up from the phone functionality.  It gives you a better timeline view and better attachment handling, but it makes you bounce to a browser page to see images that are linked to a tweet. TweetCaster This was my main Twitter app for quite a while.  It is the only one with InstaPaper integration so that you can save you a tweet and review it later.  My main problem is that it crashes too much when it can’t find a connection.  It also only previews yfrog and twitpic images and only once you go to the detail of a tweet.  Other than that it is a solid Twitter client. moTweets This is my current favorite. It has nice image display in your timeline which I have not seen on any of the other apps.  There are two modes that you can use with this app.  The first is standard to most Twitter apps that allows you to navigate to a tweet and do the usual operations.  The second is what they call Quick Buttons.  In this case you do not see the content of the tweet but go straight to the let’s get something done stage.  It is an interesting take.  I do miss the Instapaper integration and it has a tendency to show a blank timeline list once in a while after you view detail entry.  If you scroll the list it restore your timeline, but you lose you place and are put to the first entry. Seesmic I am not very fond of this app.  The first thing is that it makes you pick a “Space” when you enter the app.  This is really “which account do you want to see”.  On top of that it does not show who retweeted an entry in your timeline and then only tells you how many people RT the post when you look at the detail.  There is a Speak feature that will read you a single tweet, but you have to navigate to the tweet and then to a menu to make it work.  We will have to see if this gets better with the features in Windows Phone 8.  Other than that it is another basic feature app.  Summary In the end I am sticking with moTweets.  I would appreciate it if they added the Instapaper capability and fixed the one bug.  If they did that I would be really happy with the product. del.icio.us Tags: Twitter,Windows Phone 7,WP7,TweetCaster,moTweets,Seesmic

  • Ideal backup appliance for backup software like Bacula?

    - by Ricket
    I'm at a small company and we (the IT department of two) manage <100 client computers and a handful of servers. Currently we're using a company's appliance to handle backup; it does a small backup every night and a full backup every weekend, and a guy comes on Wednesday to take an offsite backup drive (and gives back last week's drive to swap with it). The backup is done only on the servers' hard drives, because our client computers and employees make sure not to store anything worthwhile on their own computers. So it's a pretty simple situation. Lately this system, mainly the appliance, has been having problems, so we are looking for an alternative. I'm researching other companies but also looking into what we might expect from trying to do this ourselves. There will undoubtedly be a large learning curve, but hey, that's what serverfault is for, right? :) So anyway I was looking at Bacula. Feature list sounds great, documentation is plentiful, but it's only software. So my question is, what is the ideal backup server to run the Bacula server software on? And not only the server but other related appliances. Our current backup appliance uses only hard drives, not tape drives. It has several plugged into it at one time, in hotswap bays on the front of the machine. I couldn't help but notice though, it's hardly more than Windows XP with hard drive bays, a PCI eSATA card (which connects to another appliance extension piece with 2 more bays), and their software. Since the company will take back their appliance if/when we cancel with them, where can I go to configure a server with these kinds of things? And should I consider switching to tape drives? What other concerns should I be thinking about when I pick out hardware for a backup server? Maybe I'm being naive, I'm sure Dell (and any other computer company) sells them in the small business section of their website, but I wanted to make sure that there's not some other more recommended place that other companies are getting their hardware from, and that I don't need anything special for Bacula.

  • Looking for home networking hardware and software advice

    - by phobos7
    Note: I originally wrote this up in a blog post. I've removed any affiliate links that I put in my original post to ensure I don't annoy anybody. I've recently moved home and I now need to go to the trouble of sorting out my home network yet again. We had Virgin broadband in Hertford but you can't get Virgin in the street we've moved to so I've had to go with O2 Broadband. Normally I prefer to use my own hardward, and previously used the DLink DIR-655 router which was great, but in this situation I am using the O2 Wirelss Box III since I only have an old Netgear DG834PN Wireless G modem router and I'd rather be using Wireless N. Anyway, the place we have moved into has only one phone point in the hallway, has the best TV point in one room and the best place to put the TV and other entertainment stuff in yet another room. So, networking the house up for Internet and TV is required. The diagram below shows the things that I'll have in my home network but there are three points where I'm not quite sure what hardware to us. Wireless Access Point/Bridge, that acts only as a wireless to wire bridge and not an AP, that links up a Media Centre/PC and a couple of consoles to the network. I'm pretty much settled on us an Acer Aspire Revo R3600 as my media PC, probably with Ubuntu or Windows and XBMC installed. Wireless Access Point/Bridge, that acts only as a wireless to wire bridge and not an AP, that links up a device that can decode and stream TV from a TV aerial across the network. The device that is connected to 2). At the moment I'm considering a HDHomeRun by SiliconDust. At the moment I'm considering either the TP LINK TL-WA701ND 150Mbps Wireless Lite N Access Point (very cheap at Amazon) or the Netgear 5 GHz Wireless-N HD Access Point/Bridge. I'd love to get some insight into what you would do in my situation. What Wireless Access Point/Bridge should I put at points 1) and 2)? What device should I choose for point 3) that can decode and stream a TV signal? Is the Acer Aspire Revo R3600 a good choice? ![alt text][6] Note 2: I've also posted this question on AVForums.

  • Handling bounced email when using a postfix smarthost

    - by Mark Rose
    I'm running a high availability cluster, and so far, most things work great. I have two external machines that act as outgoing mail hosts (smarthosts). The internal hosts are configured to relay all email through these two external facing hosts. My smarthosts' main.cf looks like this: myhostname = lb1.example.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases mydestination = lb1.example.com, localhost relayhost = mynetworks = 127.0.0.0/8 10.1.248.0/24 My internal hosts' main.cf looks like this: mynetworks = 127.0.0.0/8 myhostname = web1.example.com mydestination = $myhostname, localhost.$mydomain, localhost relayhost = [10.1.248.3] smtp_fallback_relay = [10.1.248.2] lb1's internal IP is 10.1.248.2, and lb2's internal IP is 10.1.248.3. On the external hosts, email for root and www-data is forwarded to [email protected] with /etc/aliases. One advantage to using the smarthost setup is that spam filters and the like can connect back to the sending sending server. All email is sent fine, and headers look like this: Received: from lb2.example.com ([198.51.100.3]) by mx.google.com with ESMTP id y17si1571259icb.76.2011.01.13.18.20.32; Thu, 13 Jan 2011 18:20:32 -0800 (PST) Received-SPF: neutral (google.com: 198.51.100.3 is neither permitted nor denied by best guess record for domain of [email protected]) client-ip=198.51.100.3; Received: from db1.example.com (unknown [10.1.248.20]) by lb2.example.com (Postfix) with ESMTP id D364823C0BE for <[email protected]>; Thu, 13 Jan 2011 21:20:31 -0500 (EST) Received: by db1.example.com (Postfix) id C9FA7760D6A; Thu, 13 Jan 2011 21:20:31 -0500 (EST) Delivered-To: www-data@localhost Received: by db1.example.com (Postfix, from userid 0) id C1632760D6C; Thu, 13 Jan 2011 21:20:31 -0500 (EST) The problem is bounced/reject email. The external machine tries to forward the email back to the internal machine, e.g. www-data on web1 sending an email that bounces (such as a user signing up with a bad email address). An additional complication is using Google mail for the main example.com domain. In lieu of specifying every internal host in the external hosts' mydestination, is there a better way of setting things up, keeping in mind I can't adjust touch the mx for example.com?

  • Indesign Import XML into Automatic Page generation, data merge

    - by taudep
    I've created some InDesign Pages that I want to use as templates. I've created an XML file with all the appropriate data. I want to merge the XML data with the InDesign page and have a few hundred pages automatically generated. I've been reading online and working with InDesign's "Import XML" features without any luck. The documentation has been pretty poor for me. And Google searches haven't returned much fruitful. Edit: I'm updating this to now include my present steps 1) I create a Master Page of my template 2) I add a bunch of text frames where I want the imported data from the XML file to be places 3) I open the "Tags" window and Import and XML file 4) I mark my text frames in the Master Document with the appropriate tags 5) I then add a lot of pages (like 200) to the document 6) Then I use "Import XML" to try and get the data brought in and filled across all 200 pages. This is where I fail. So there's something I'm missing. It might be that InDesign doesn't work as I'm expecting... Anyone have any good tips for mail-merge like functionality with an XML document and auto-generation of InDesign pages? BTW, here's an example of Adobe's great documentation for merging repeated XML elements. There's gotta be more...InDesign CS4 Docs: XML-Importing XML-Working with Repeating Data EDIT: Here's some of the sample XML, notice the ITEM will repeat.

  • Vista install works on one computer, but bluescreens another (on which Vista is known to work)

    - by Ken
    I hope my explanations make some sense -- please ask for clarification if they don't. I had a computer running Windows Vista (Ultimate, 64-bit). All was well! Then one day there was a nasty power surge at the office, and it died. (We didn't have surge protectors at the office, unfortunately. I assumed our lines were conditioned elsewhere, or was not an issue here. Oops.) After some testing, it was determined that the PSU, motherboard, and RAM were bad. While waiting for new hardware to arrive, I put my hard disk in a spare PC which had identical parts (mobo/CPU/RAM/PSU/video). Everything worked perfectly. The only way I could even tell it wasn't my computer is because Vista asked to re-activate itself with the new hardware, which worked fine, too. So the hard disk seems OK. Then the new parts arrived. The old motherboard model is no longer manufactured, so it's a new one with the same CPU/RAM/videocard/etc. slots. The PSU is also new, while the RAM I'm using is from the spare PC mentioned above. When I put it together and tried booting with my old hard disk, it starts to boot Windows, and then (fairly early in the process) gives a bluescreen and immediately reboots (so I can't see whatever the bluescreen is trying to tell me). I tried "safe mode", which also bluescreened. I tried booting the Vista DVD and running the repair utility, which found a Vista install, confirmed that it would not boot, and, eventually, declared that it was unable to repair it. I installed Vista fresh on a new hard disk, with the new mobo/etc., and it works perfectly. (That's what I'm running now.) I've also booted a Linux CD here, which ran great, and I've run Memtest86+ for a while, which found no errors. So all the hardware apart from the old hard disk seems OK, too. I don't think the problem is with my old Vista hard disk, since I used that with another mobo/CPU just fine. I don't think it's any other part of the new hardware, since I'm able to use it (and test it) with no trouble. It's just the combination of my old Vista install plus the new PC hardware that's not happy. I can get my data off my old hard disk and onto my new hard disk, and reinstall my apps, but it would be nice if I could fix things so I could continue to use my old hard disk as before. The latest hypothesis I've heard is that Vista had trouble with the new hardware (i.e., motherboard), but we have no idea what to do about that (except Safe Mode, which didn't work). Suggestions? Hypotheses for what's not right about this combination of Vista install and motherboard? Thanks!

  • Migrate from MySQL to PostgreSQL on Linux (Kubuntu)

    - by Dave Jarvis
    Storyline Trying to migrate a database from MySQL to PostgreSQL. All the documentation I have read covers, in great detail, how to migrate the structure. I have found very little documentation on migrating the data. The schema has 13 tables (which have been migrated successfully) and 9 GB of data. MySQL version: 5.1.x PostgreSQL version: 8.4.x I want to use the R programming language to analyze the data using SQL select statements; PostgreSQL has PL/R, but MySQL has nothing (as far as I can tell). A long time ago in a galaxy far, far away... Create the database location (/var has insufficient space; also dislike having the PostgreSQL version number everywhere -- upgrading would break scripts!): sudo mkdir -p /home/postgres/main sudo cp -Rp /var/lib/postgresql/8.4/main /home/postgres sudo chown -R postgres.postgres /home/postgres sudo chmod -R 700 /home/postgres sudo usermod -d /home/postgres/ postgres All good to here. Next, restart the server and configure the database using these installation instructions: sudo apt-get install postgresql pgadmin3 sudo /etc/init.d/postgresql-8.4 stop sudo vi /etc/postgresql/8.4/main/postgresql.conf Change data_directory to /home/postgres/main sudo /etc/init.d/postgresql-8.4 start sudo -u postgres psql postgres \password postgres sudo -u postgres createdb climate pgadmin3 Use pgadmin3 to configure the database and create a schema. A New Hope The episode began in a remote shell known as bash, with both databases running, and the installation of a command with a most unusual logo: SQL Fairy. perl Makefile.PL sudo make install sudo apt-get install perl-doc (strangely, it is not called perldoc) perldoc SQL::Translator::Manual Extract a PostgreSQL-friendly DDL and all the MySQL data: sqlt -f DBI --dsn dbi:mysql:climate --db-user user --db-password password -t PostgreSQL > climate-pg-ddl.sql mysqldump --skip-add-locks --complete-insert --no-create-db --no-create-info --quick --result-file="climate-my.sql" --databases climate --skip-comments -u root -p The Database Strikes Back Recreate the structure in PostgreSQL as follows: pgadmin3 (switch to it) Click the Execute arbitrary SQL queries icon Open climate-pg-ddl.sql Search for TABLE " replace with TABLE climate." (insert the schema name climate) Search for on " replace with on climate." (insert the schema name climate) Press F5 to execute This results in: Query returned successfully with no result in 122 ms. Replies of the Jedi At this point I am stumped. Where do I go from here (what are the steps) to convert climate-my.sql to climate-pg.sql so that they can be executed against PostgreSQL? How to I make sure the indexes are copied over correctly (to maintain referential integrity; I don't have constraints at the moment to ease the transition)? How do I ensure that adding new rows in PostgreSQL will start enumerating from the index of the last row inserted (and not conflict with an existing primary key from the sequence)? Resources A fair bit of information was needed to get this far: https://help.ubuntu.com/community/PostgreSQL http://articles.sitepoint.com/article/site-mysql-postgresql-1 http://wiki.postgresql.org/wiki/Converting_from_other_Databases_to_PostgreSQL#MySQL http://pgfoundry.org/frs/shownotes.php?release_id=810 http://sqlfairy.sourceforge.net/ Thank you!

  • using own mail server with external domain and dns. Now have internal dns. dkim test not working

    - by mojotaker
    I am not very knowledgeable in this area, but have been able to make great head way. Now i am stuck I setup my own mail server, e.g mailbox.example.com. I had the domain dns point to my mail server in my office. i was able to set up everything working fine. such as dkim and spf records. Recently i decided to setup an internal dns server in the office so as to resolve some addresses for some development servers internally. Ok the problem now is my mail server is sitting on the internal dns server (the mail server is on the same box as the dns server) its still able to send and receive emails but not sure if dkim is working properly. when i try to do a dkim test "amavisd test keys" i get "invalid (public key: not available)" and i know that that means i have a dns issue. so what should i do? I am currently looking at my internal dns zonefile and i dont know what to do (i am using bind dns server on an ubuntu-server box). do i configure a dkim txt record on the local dns ? or is there a way to forward dkim "request" to the external dns ? or do i have this whole thing done wrong ? To be clear Basically my internal domain name is the same as my external domain name (i.e example.com) i have a mail server within my internal domain mailbox.example.com, that uses my external domain dns (external dns has been setup to point to my emailserver (which of course is now sitting behind my internal dns)) dkim (i dont think its working because it fails the dkim test") Need help in determing the proper setup What is the proper way to set this up ? thank you Update: Here is my local dns zone file ; ; BIND data file for local loopback interface ; $TTL 604800 @ IN SOA webserver.example.com. root.example.com.

  • Mac OS X behind OpenLDAP and Samba

    - by Sam Hammamy
    I have been battling for a week now to get my Mac (Mountain Lion) to authenticate on my home network's OpenLDAP and Samba. From several sources, like the Ubuntu community docs, and other blogs, and after a hell of a lot of trial and error and piecing things together, I have created a samba.ldif that will pass the smbldap-populate when combined with apple.ldif and I have a fully functional OpenLDAP server and a Samba PDC that uses LDAP to authenticate the OS X Machine. The problem is that when I login, the home directory is not created or pulled from the server. I get the following in system.log Sep 21 06:09:15 Sams-MacBook-Pro.local SecurityAgent[265]: User info context values set for sam Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in pam_sm_authenticate(): Got user: sam Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in pam_sm_authenticate(): Got ruser: (null) Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in pam_sm_authenticate(): Got service: authorization Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in od_principal_for_user(): no authauth availale for user.

  • openstack, bridging, netfilter and dnat

    - by Craig Sanders
    In a recent upgrade (from Openstack Diablo on Ubuntu Lucid to Openstack Essex on Ubuntu Precise), we found that DNS packets were frequently (almost always) dropped on the bridge interface (br100). For our compute-node hosts, that's a Mellanox MT26428 using the mlx4_en driver module. We've found two workarounds for this: Use an old lucid kernel (e.g. 2.6.32-41-generic). This causes other problems, in particular the lack of cgroups and the old version of the kvm and kvm_amd modules (we suspect the kvm module version is the source of a bug we're seeing where occasionally a VM will use 100% CPU). We've been running with this for the last few months, but can't stay here forever. With the newer Ubuntu Precise kernels (3.2.x), we've found that if we use sysctl to disable netfilter on bridge (see sysctl settings below) that DNS started working perfectly again. We thought this was the solution to our problem until we realised that turning off netfilter on the bridge interface will, of course, mean that the DNAT rule to redirect VM requests for the nova-api-metadata server (i.e. redirect packets destined for 169.254.169.254:80 to compute-node's-IP:8775) will be completely bypassed. Long-story short: with 3.x kernels, we can have reliable networking and broken metadata service or we can have broken networking and a metadata service that would work fine if there were any VMs to service. We haven't yet found a way to have both. Anyone seen this problem or anything like it before? got a fix? or a pointer in the right direction? Our suspicion is that it's specific to the Mellanox driver, but we're not sure of that (we've tried several different versions of the mlx4_en driver, starting with the version built-in to the 3.2.x kernels all the way up to the latest 1.5.8.3 driver from the mellanox web site. The mlx4_en driver in the 3.5.x kernel from Quantal doesn't work at all) BTW, our compute nodes have supermicro H8DGT motherboards with built-in mellanox NIC: 02:00.0 InfiniBand: Mellanox Technologies MT26428 [ConnectX VPI PCIe 2.0 5GT/s - IB QDR / 10GigE] (rev b0) we're not using the other two NICs in the system, only the Mellanox and the IPMI card are connected. Bridge netfilter sysctl settings: net.bridge.bridge-nf-call-arptables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-ip6tables = 0 Since discovering this bridge-nf sysctl workaround, we've found a few pages on the net recommending exactly this (including Openstack's latest network troubleshooting page and a launchpad bug report that linked to this blog-post that has a great description of the problem and the solution)....it's easier to find stuff when you know what to search for :), but we haven't found anything on the DNAT issue that it causes.

  • Indesign Import XML into Automatic Page generation, data merge

    - by taudep
    I've created some InDesign Pages that I want to use as templates. I've created an XML file with all the appropriate data. I want to merge the XML data with the InDesign page and have a few hundred pages automatically generated. I've been reading online and working with InDesign's "Import XML" features without any luck. The documentation has been pretty poor for me. And Google searches haven't returned much fruitful. Here are my present steps: I create a Master Page of my template I add a bunch of text frames where I want the imported data from the XML file to be places I open the "Tags" window and Import and XML file I mark my text frames in the Master Document with the appropriate tags I then add a lot of pages (like 200) to the document Then I use "Import XML" to try and get the data brought in and filled across all 200 pages. This is where I fail. There's something I'm missing. It might be that InDesign doesn't work as I'm expecting... Does anyone have any good tips for mail-merge like functionality with an XML document and auto-generation of InDesign pages? By the way, here's an example of Adobe's great documentation for merging repeated XML elements. There's got to be more... InDesign CS4 Docs: XML-Importing XML-Working with Repeating Data Here's some of the sample XML, notice the ITEM will repeat. I've also truncated the data in the "desc" tag: <output> <item> <user_name>taude</user_name> <date>2009-02-21</date> <title>Wishful Thinking</title> <desc>Skiing up in Vermont on a beautiful day.

  • Alpha plugin in GStreamer not working

    - by Miguel Escriva
    Hi! I'm trying to compose two videos, and I'm using the alpha plug-in to make the white color transparent. To test the alpha plug-in I'm creating the pipeline with gst-launch. The first test I done was: gst-launch videotestsrc pattern=smpte75 \ ! alpha method=custom target-r=255 target-g=255 target-b=255 angle=10 \ ! videomixer name=mixer ! ffmpegcolorspace ! autovideosink \ videotestsrc pattern=snow ! mixer. and it works great! Then I created two videos with those lines: gst-launch videotestsrc pattern=snow ! ffmpegcolorspace ! theoraenc ! oggmux ! filesink location=snow.ogv gst-launch videotestsrc pattern=smpte75 ! ffmpegcolorspace ! theoraenc ! oggmux ! filesink location=bars75.ogv And changed the videotestsrc to a filesrc and it continues working gst-launch filesrc location=bars75.ogv ! decodebin2 \ ! alpha method=custom target-r=255 target-g=255 target-b=255 angle=10 \ ! videomixer name=mixer ! ffmpegcolorspace ! autovideosink \ filesrc location=snow.ogv ! decodebin2 ! alpha ! mixer. But, when I use the ideo I want to compose, I'm not able to make the white color transparent gst-launch filesrc location=video.ogv ! decodebin2 \ ! alpha method=custom target-r=255 target-g=255 target-b=255 angle=10 \ ! videomixer name=mixer ! ffmpegcolorspace ! autovideosink \ filesrc location=snow.ogv ! decodebin2 ! alpha ! mixer. Can you help me? Any idea what is happening? I'm using GStreamer 0.10.28 You can download the test videos from here: http://polimedia.upv.es/pub/gst/gst.zip Thanks in advance, Miguel Escriva

  • OSX 10.6.6 SSH md5 break-in check

    - by Alex
    Information Recently one of the linux servers that I access was compromised to steal passwords and ssh keys using a modified ssh binary. This lead me to question if the attacker had compromised my OSX Laptop which had ssh access turned on. A sophos virus scan turned up nothing, and I did not have rkhunter installed before the attack, so I could not compare hashes of the system binaries to be sure. However because OSX is relatively standard for each of their major releases, I asked fiends for md5 hashes md5 /usr/bin/ssh and md5 /usr/sbin/sshd as a basic first check to see if there was anything different about my machine. A few emails later I have found the following data: Version (Arch) [N] MD5 (/usr/bin/ssh) MD5 (/usr/sbin/sshd) OSX 10.5.8 (PPC) [3] 1e9fd483eef23464ec61c815f7984d61 9d32a36294565368728c18de466e69f1 OSX 10.5.8 (intel) [5] 1e9fd483eef23464ec61c815f7984d61 9d32a36294565368728c18de466e69f1 OSX 10.6.x (intel) [7] 591fbe723011c17b6ce41c537353b059 e781fad4fc86cf652f6df22106e0bf0e OSX 10.6.x (intel) [4] 58be068ad5e575c303ec348a1c71d48b 33dafd419194b04a558c8404b484f650 Mine 10.6.6 (intel) df344cc00a294c91230c65e8b7332a79 b5094ccf4cd074aaf573d4f5df75906a where N is the number of machines with with that MD5, and the last row is my laptop. The sample is relatively heterogeneous spaning a few years of different makes and models of Apples, and different versions of 10.6.x. The different hash for my system made me worried that these binaries might have been compromised. So I made sure that my backup for the week was good, and dived into formatting my system and reinstalling OSX. After reinstalling OSX from the manufacturer DVD, I found that the MD5 hash did not change for either ssh, or sshd. Goal Make sure that my system is does not have any malicious software. Should I be worried that this base install of OSX (with no other software installed) has been compromised? I have also updated my system to 10.6.6 and found no change as well. Other Information I am not sure if this is helpful information, but my laptop is a i7 15 inch MacBook Pro bought in Nov 2010, and here is some output from system_profiler: System Software Overview: System Version: Mac OS X 10.6.6 (10J567) Kernel Version: Darwin 10.6.0 64-bit Kernel and Extensions: No Time since boot: 1:37 Hardware: Hardware Overview: Model Name: MacBook Model Identifier: MacBook6,2 Processor Name: Intel Core i7 Processor Speed: 2.66 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per core): 256 KB L3 Cache: 4 MB Memory: 4 GB Processor Interconnect Speed: 4.8 GT/s Boot ROM Version: MBP61.0057.B0C SMC Version (system): 1.58f16 Sudden Motion Sensor: State: Enabled On the laptop, I find: $ codesign -vvv /usr/bin/ssh /usr/bin/ssh: valid on disk /usr/bin/ssh: satisfies its Designated Requirement $ codesign -vvv /usr/sbin/sshd /usr/sbin/sshd: valid on disk /usr/sbin/sshd: satisfies its Designated Requirement $ ls -la /usr/bin/ssh -rwxr-xr-x 1 root wheel 1001520 Feb 11 2010 /usr/bin/ssh $ ls -la /usr/sbin/sshd -rwxr-xr-x 1 root wheel 1304800 Feb 11 2010 /usr/sbin/sshd $ ls -la /sbin/md5 -r-xr-xr-x 1 root wheel 65232 May 18 2009 /sbin/md5 Update So far I have not gotten an answer about this question, but if you could help by increasing the number of hashes that I can compare against, that would be great. To get hashes, and version numbers, run the following on osx: md5 /usr/bin/ssh md5 /usr/sbin/sshd ssh -V sw_vers

  • An alternative to Google Talk, AIM, MSN, et al [closed]

    - by mkaito
    I'm not entirely sure whether this part of stack exchange is the most adequate for my question, but it would seem to me that people sharing this kind of concern would converge either here, or possibly on a more unix-specific sub site. Either way, here goes. Background Feel free to skip to The Question, below. This should, however, help those interested understand where I'm coming from, and where I expect to get, messaging-wise. My online talking place-to-go has been IRC for the last fifteen years. I think it's a great protocol, and clients out there are very good. I still use, and will always continue to use IRC for most of my chat needs. But then, there is private instant messaging. While IRC can solve this with queries and DCC chats, the protocol just isn't meant to work too well on intermittent connections, such as a mobile device, where you can often walk around places with low signal. I used MSN for a while, but didn't like it. The concept was awesome, but I think Microsoft didn't get the implementation quite right. When they started adding all that eye candy, and my buddies started flooding me with custom icons and buzzing my screen to it's knees, I shut my account and told folks that missed me to just email or call me. Much whining happened, I got called many weird things for not using MSN, but folks eventually got over it. Next, Google Talk came along, and seemed to be a lot better than MSN ever was. The protocol was open, so I could use whatever client I felt a fancy for. With the advent of smart phones, I just got myself a gtalk client on the phone, and have had a really decent integrated mostly-universal IM solution. Over the last few months, all Google services have been feeling flaky. IMs will often arrive anywhere between twenty minutes and one hour after being sent, clients will randomly disconnect, client priorities seem to work sometimes, and sometimes just a random device of those connected will get an IM. I think the time has come to look for greener grass. The Question It's rather hard to put what I'm looking for into precise words. I guess I just want something that is kind of like MSN/Gtalk, but that doesn't let me down when I need it. IRC is pretty much perfect, but the protocol just isn't designed to work well on mobile devices. Really, at this point I'm considering sticking to IRC for desktop messaging, and SMS/email on the phone, but I hope that in this day and age there is something better out there.

  • Linux Mint Wireless doesn't connect

  • Understanding vhosts settings

    - by Matt
    Ok so i have a server and I want to put a few applications on and i am having vhost configuration problems. Here is what i have and I want some direction on what i am doing wrong...ok so the first file is /etc/apache2/ports.conf NameVirtualHost 184.106.111.142:80 Listen 80 <IfModule mod_ssl.c> Listen 443 </IfModule> <IfModule mod_gnutls.c> Listen 443 </IfModule> then i have /etc/apache2/sites-available/somesite.com <VirtualHost 184.106.111.142:80> ServerAdmin [email protected] ServerName somesite.com ServerAlias www.somesite.com DocumentRoot /srv/www/somesite.com/ ErrorLog /srv/www/somesite.com/logs/error.log CustomLog /srv/www/somesite.com/logs/access.log combined <Directory "/srv/www/somesite.com/"> AllowOverride all Options -MultiViews </Directory> </VirtualHost> when i visit somesite.com everything works great but when i add another vhost and lets say thats named anothersite.com. So i have /etc/apache2/sites-available/anothersite.com <VirtualHost 184.106.111.142:80> ServerAdmin [email protected] ServerName anothersite.com ServerAlias www.anothersite.com DocumentRoot /srv/www/anothersite.com/ ErrorLog /srv/www/anothersite.com/logs/error.log CustomLog /srv/www/anothersite.com/logs/access.log combined <Directory "/srv/www/anothersite.com/"> AllowOverride all Options -MultiViews </Directory> </VirtualHost> then i run the following commands >> sudo a2ensite anothersite.com Enabling site anothersite.com. Run '/etc/init.d/apache2 reload' to activate new configuration! >> /etc/init.d/apache2 reload * Reloading web server config apache2 ...done. but when i visit anothersite.com or somesite.com they are both down..What is going on with the vhosts. Could it be the NameVirtualHost declaration with the ip or something...maybe my understanding of vhost settings is not clear. What i dont understand is why do both site now all the sudden not work at all.I would highly appreciate the clarity By the way anothersite.com or somesite.com are the only things I changed to make it more readable

  • long access times and errors in iis application

    - by user55862
    I am having an issue with an IIS application (details of environment at the end of the message). The web site works great most of the time and I cannot reproduce any error in our test system. On the live system however with on averare of 5-15 requests per second I have a problem with that some requests (about 0.05%) will take over 300 seconds to complete. The other requests complete withing 5-10 seconds. It seem like if all the errornous requests end up with a Timer_EntityBody error in the error log. I have never seen this as an end user but I guess that they will receive some kind of error message. I am trying to find out what can be causing this errornous behaviour. Any ideas are welcome. I have read something about that there can be an MTU issue if ICMP and MTU protocols are blocked in the firewall. Does that sound reasonable? I have also read about updating to IIS 7 should do the trick. Does it sound reasonable? I think that the problem has another cause but I have no idea of what. I have tried running hte perormance monitor, monitoring for database locks and active transaction counts. I can see some of these in the perfmon log for the MSSQL server (another machine) for example: Active transactions is sometimes peaking and sometimes for long periods Lock waits per seconds is sometimes peaking Transactions per second is sometimes peaking Page IO Latch wait is sometimes peaking Lock wait time (ms) is sometimes peaking But I cannot see that any of these correlate to the errors in the IIS error log. On the IIS server machine I can also see with perfmon that some values peak a few times during a day: Request execution time Avg disk queue length I can neither see that any of these correlate to the errors in the IIS error log. In the below code I have anonymized by replacing some parts with HIDDEN The following can be seen in the access log 2010-10-01 08:35:05 W3SVC1301873091 **HIDDEN** POST /**HIDDEN**/Modules/BalanceModule.aspx - 80 - **HIDDEN** Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.4506.2152;+.NET+CLR+3.5.30729;+.NET4.0C;+.NET4.0E) ASP.NET_SessionId=**HIDDEN** 400 0 64 0 2241 127799 At the same time the following can be seen in the error log: 2010-10-01 08:35:05 **HIDDEN** 1999 **HIDDEN** 80 HTTP/1.0 POST /**HIDDEN**/Modules/BalanceModule.aspx - 1301873091 Timer_EntityBody Test+Pool I can tell the following about the environment: Server: Windows Server 2003 x64 SP2 running on VMWare HTTP Server: IIS v6.0 with ASP.NET 2.0.50727 Antivirus: Trend Micro OfficeScan (Is it a good idea to have this on a server?)

  • Need help making an ODBC MySQL Connection

    - by Andy Moore
    Short Version: How do I connect from PowerShell to an ODBC 5.1 MySQL Driver? I can't seem to find any connection strings that accurately have a "Provider" field for this particular instance. (See bottom of this question for examples/errors) ===== Long Version: I'm not a server guy, and I've been handed the task of setting up PowerGadgets on our network. I have a MySQL server running on a Linux box, that is configured for remote access and has a user defined for remote access as well. On my windows desktop PC, I have PowerGadgets installed. I installed the MySQL ODBC 5.1 connector, and went to Control Panel Data Sources and set up a User DSN connection to the database. The connection, user, and pass seem to be correct because it lists the tables of the database in my windows control panel. Where I'm running into trouble is in 3 places in PowerGadgets: When selecting a data source, I can select "SQL Server". Inputting the servers IP address does not work and I can't get this option to work at all. When selecting a data source, I can select "OleDB". This screen has a wizard on it, that appears to populate all the correct information (including database table names!) for me. "Test Connection" runs great. But if I try to complete the wizard, I get the error "The .NET Framework data provider for OLEDB does not support the MS Ole DB provider for ODBC Drivers." When selecting a data source, I can select "ODBC". This screen does not have a wizard and I cannot figure out a "connection string" that works. Typically it will respond with the error "The field 'Provider' is missing". Googling ODBC connection strings doesn't reveal any examples with a "provider" field and have no idea what to put in here. The connection string (for #2) above contains "SQLOLEDB" as a provider, and upon inputting that value into this connection string I get the same connection error that #2 gets. I believe I can solve my problems by figuring out a connection string for #3 but don't know where to get started. (PowerGadgets also allows for PowerShell support but I believe I will run into the same problem there) == Here's my current PowerShell connection that doesn't work: invoke-sql -connection "Driver={MySQL ODBC 5.1 Driver};Initial Catalog=hq_live;Data Source=HQDB" -sql "Select * FROM accounts" Spits back the error: "Invoke-Sql : An OLE DB Provider was not specified in the ConnectionString. An example would be, 'Provider=SQLOLEDB;'. == Another string that doesn't work: invoke-sql -connection "Provider=MSDASQL.1;Persist Security Info=False;Data Source=HQDB;Initial Catalog=hq_live" -sql "select * from accounts" And the error: The .Net Framework Data Provider for OLEDB (System.Data.OleDb) does not support the Microsoft OLE DB Provider for ODBC Drivers (MSDASQL). Use the .Net Framework Data Provider for ODBC (System.Data.Odbc).

  • Issue with VMWare vSphere and NFS: re occurring apd state

    - by Bastian N.
    I am experiencing issues with VMWare vSphere 5.1 and NFS storage on 2 different setups, which result in an "All Path Down" state for the NFS shares. This first happened once or twice a day, but lately it occurs much more frequent, as specially when Acronis Backup jobs are running. Setup 1 (Production): 2 ESXi 5.1 hosts (Essentials Plus) + OpenFiler with NFS as storage Setup 2 (Lab): 1 ESXi 5.1 host + Ubuntu 12.04 LTS with NFS as storage Here is an example from the vmkernel.log: 2013-05-28T08:07:33.479Z cpu0:2054)StorageApdHandler: 248: APD Timer started for ident [987c2dd0-02658e1e] 2013-05-28T08:07:33.479Z cpu0:2054)StorageApdHandler: 395: Device or filesystem with identifier [987c2dd0-02658e1e] has entered the All Paths Down state. 2013-05-28T08:07:33.479Z cpu0:2054)StorageApdHandler: 846: APD Start for ident [987c2dd0-02658e1e]! 2013-05-28T08:07:37.485Z cpu0:2052)NFSLock: 610: Stop accessing fd 0x410007e4cf28 3 2013-05-28T08:07:37.485Z cpu0:2052)NFSLock: 610: Stop accessing fd 0x410007e4d0e8 3 2013-05-28T08:07:41.280Z cpu1:2049)StorageApdHandler: 277: APD Timer killed for ident [987c2dd0-02658e1e] 2013-05-28T08:07:41.280Z cpu1:2049)StorageApdHandler: 402: Device or filesystem with identifier [987c2dd0-02658e1e] has exited the All Paths Down state. 2013-05-28T08:07:41.281Z cpu1:2049)StorageApdHandler: 902: APD Exit for ident [987c2dd0-02658e1e]! 2013-05-28T08:07:52.300Z cpu1:3679)NFSLock: 570: Start accessing fd 0x410007e4d0e8 again 2013-05-28T08:07:52.300Z cpu1:3679)NFSLock: 570: Start accessing fd 0x410007e4cf28 again As long as the issue occurred once or twice a day it really wasn't a problem, but now this issue has impact on the VMs. The VMs get slow or even hang, resulting in a reset through vCenter in the production environment. I searched the web extensively and asked in forums, but till now nobody was able to help me. Based on blog posts and VMWare KB articles I tried the following NFS settings: Net.TcpipHeapSize = 32 Net.TcpipHeapMax = 128 NFS.HartbeatFrequency = 12 NFS.HartbeatMaxFailures = 10 NFS.HartbeatTimeout = 5 NFS.MaxQueueDepth = 64 Instead of NFS.MaxQueueDepth = 64 I already tried other settings like NFS.MaxQueueDepth = 32 or even NFS.MaxQueueDepth = 1. Unfortunately without any luck. It would be great if someone could help me on this issue. It is really annoying. Thanks in advance for all the help. [UPDATE] As I explained in the comment below, here is the network setup: On the production setup the NFS traffic is bound to a separate VLAN with ID 20. I am using a HP 1810 24 Port Switch. The OpenFiler system is connected to the VLAN with 4 Intel GbE NICs with dynamic LACP. The ESXis both have 4 Intel GbE NICs using 2 static LACP trunks containing 2 NICs each. One pair is connected to the regular LAN and the other one to the VLAN 20. And here is a screenshot of the vSwitch: Switch configuration: Port configuration: On the lab setup its a single Intel NIC on each side without VLAN, but with different IP subnet.

  • Multiple subnets on isc-dhcp-server using ddns with bind9

    - by legioxi
    On my network I have two subnets: 10.100.1.0/24 - Wired/wireless 10.100.7.0/24 - VPN Both subnets are served by isc-dhcp-server running on a Debian VM. This same VM runs bind9 for my DNS. ISC-DHCP-SERVER is configured to use DDNS and update BIND9 with hosts/IPs. Everything runs great until a device drops off the wired/wireless network and pops onto the VPN. When connecting on the VPN, a DHCP lease is handed out on the new subnet but DDNS does not update BIND9. Since the device has A/TXT/PTR records it appears ISC-DHCP-SERVER won't switch them to the new IP. The logs show: Connect to wireless: Nov 6 20:55:13 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': adding an RR at 'demo-iphone.internal.mydomain.com' A Nov 6 20:55:13 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': adding an RR at 'demo-iphone.internal.mydomain.com' TXT Nov 6 20:55:13 core-server dhcpd: DHCPACK on 10.100.1.160 to FF:FF:FF:FF:FF:FF (demo-iphone) via eth0 Nov 6 20:55:13 core-server dhcpd: Added new forward map from demo-iphone.internal.mydomain.com to 10.100.1.160 Nov 6 20:55:13 core-server dhcpd: Added reverse map from 160.49.21.172.in-addr.arpa. to demo-iphone.internal.mydomain.com Switch to VPN: Nov 6 20:56:34 core-server dhcpd: DHCPOFFER on 10.100.7.101 to BB:BB:BB:BB:BB:BB (demo-iphone) via 10.100.7.0 Nov 6 20:56:34 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': update unsuccessful: demo-iphone.internal.mydomain.com: 'name not in use' prerequisite not satisfied (YXDOMAIN) Nov 6 20:56:34 core-server dhcpd: DHCPREQUEST for 10.100.7.101 (10.100.1.2) from BB:BB:BB:BB:BB:BB (demo-iphone) via 10.100.7.0 Nov 6 20:56:34 core-server dhcpd: DHCPACK on 10.100.7.101 to BB:BB:BB:BB:BB:BB (demo-iphone) via 10.100.7.0 Nov 6 20:56:34 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': update unsuccessful: demo-iphone.internal.mydomain.com/TXT: 'RRset exists (value dependent)' prerequisite not satisfied (NXRRSET) Nov 6 20:56:34 core-server dhcpd: Forward map from demo-iphone.internal.mydomain.com to 10.100.7.101 FAILED: Has an address record but no DHCID, not mine. One thing to note is that the MAC of the device when connecting via VPN is the MAC of my Cisco ASA5512X and not the actual device. The ASA is relaying the DHCP request from the VPN client to the VM running ISC-DHCP-SERVER. Is there a way to get DDNS working in this scenario?

  • Layer 3 switch routing

    - by Yoshiwaan
    I need help moving over to using our layer 3 switch as the inter vlan routing device rather than our cisco router. I've mostly got it working but I've got stuck near the end and need some advice (I think I just need a bit of education on the subject really). Cur I have a Dell PowerConnect 7048 connecting to a Cisco 1841 router. I've got a few key excerpts from the configs to provide the key information. On the powerconnect I have the following: ip routing ip default-gateway 172.31.14.1 ip route 0.0.0.0 0.0.0.0 172.31.14.1 253 ! interface vlan 1 ip address 172.31.14.254 255.255.255.0 exit interface vlan 2 ip address 172.31.19.254 255.255.255.0 exit interface vlan 4 ip address 172.31.16.254 255.255.255.0 ! interface Gi1/0/1 description 'Link to L7Router01' switchport mode trunk switchport trunk allowed vlan except 3,7-4093 exit ! and on the Cisco the following: interface FastEthernet0/0 ip address 172.31.14.1 255.255.255.0 ip nat inside ip virtual-reassembly ! interface FastEthernet0/0.2 description Accounts VLAN encapsulation dot1Q 2 ip address 172.31.19.1 255.255.255.0 ip nat inside ip virtual-reassembly ! interface FastEthernet0/0.4 description Voice VLAN encapsulation dot1Q 4 ip address 172.31.16.1 255.255.255.0 ip nat inside ip virtual-reassembly ! So what I'm doing is moving clients over so that their default gateway is a 172.31.x.254 address rather than a 172.31.x.1 address. This works great for inter-vlan routing, I have no issues with this. The switch can also access the router no worries, and users on the 172.31.14.0/24 network can access all interfaces and sub-interfaces on the router, including 172.31.14.1. They can also access all of the interfaces that the router connects off to, no worries there. The problem I have is that users on the 172.31.16.0/24 and 172.31.19.0/24 subnets cannot access either 172.31.14.1 or any of the subnets the router connects to. They can, however, connect to BOTH of the sub interfaces on the router from either subnet. What am I missing here? Why can't the vlans connect to the non-sub interface on the router? Are tagged packets being sent to this interface?
