• Merging Two KML Files to Display Them with Different Marker Icons on Google Maps

  - by Maxim Z.

  Let's say that I have two spreadsheets with addresses. I uploaded these spreadsheets into Google Fusion Tables, geocoded the addresses, and exported the results as KML files. Now, I want to take these two KML files and merge them, while maintaining the location data and using it to map the points with Google Maps. Well, I found a way to easily merge the KML files: import both of them into a "My Maps" map with Google Maps! However, my problem is this: when I do that, all of the locations in my data have the same marker icon on the map. From past experience, I know that these markers can be somehow defined inside the KML files. Is it possible to combine these two KML files while giving one's points one marker icon and the other's points another marker icon? Just in case my question is confusing, what I mean, is giving the first set of points blue markers, for example, and the other set of points red markers, so that they can be overlayed.

• Unable to connect to the Report Server

  - by pghcpa

  Win/7 Professional SQL Server 2008 R2 Express Reporting Services Configuration Manager When I launch it, shows correct Server Name, but report server instance is blank. When I press FIND I get: "Unable to connect to the Report Server " This is my development workstation, so no IIS installed. Seems to work fine on XP. SSMS works fine - no issues. I tried uninstalling SQL Server completely, rebooting, reinstalling a fresh download. Same result. I've googled every article I can find - nothing. Can anyone point me in the right direction in case you've come across this yourself? Thanks.

• Downloading specific video renditions in WebCenter Content

  - by Kyle Hatlestad

  I recently had a question come up on one of my previous blog articles about downloading a specific video rendition.  When accessing image renditions, you simply need to pass in the 'Rendition=<rendition name>' parameter on the GET_FILE service and it will be returned.  But when you try that with videos, you get the error message, "Unable to download '<Content ID>'. The rendition or attachment '<Rendition Name>' could not be found in the list manifest of the revision with internal revision ID '<dID>'. Through the interface, it exposes the ability to download, but utilizes the Content Basket to bundle one or more videos and download them as a zip.   I had never tried this with videos, but thought they had worked the same way.  Well, it turns out you need to pass in an extra parameter in the case of videos.  So if you pass in parameter of 'AuxRenditionType=media', that will allow the GET_FILE service to download the video (e.g. http://server/cs/idcplg?IdcService=GET_FILE&dID=11012&dDocName=WCCBASE9010812&allowInterrupt=1 &Rendition=QuickTime&AuxRenditionType=media).  And if you haven't seen the David After Dentist video, I'd highly recommend it!

• Apache not running from rc.d on FreeBSD

  - by Oksana Molotova

  I'm using FreeBSD 8.3 and Apache 2.2. I didn't install Apache from ports, instead compiled it from source because I wanted to move the binary and configuration to a different path (I'm centering all of the major production daemons and their configurations in a single place). In any case, I based the /usr/local/etc/rc.d/apache22 file on one from a different server where it was installed from ports, I only modified the binary and config paths within. I can manually execute it with /usr/local/etc/rc.d/apache22 start, however even with apache22_enable="YES" in /etc/rc.conf it fails to start. All permissions and ownership are identical to the other server where it works. What am I missing and is there a way to debug this kind of thing?

• Does JAXP natively parse HTML?

  - by ikmac

  So, I whip up a quick test case in Java 7 to grab a couple of elements from random URIs, and see if the built-in parsing stuff will do what I need. Here's the basic setup (with exception handling etc omitted): DocumentBuilderFactory dbfac = DocumentBuilderFactory.newInstance(); DocumentBuilder dbuild = dbfac.newDocumentBuilder(); Document doc = dbuild.parse("uri-goes-here"); With no error handler installed, the parse method throws exceptions on fatal parse errors. When getting the standard Apache 2.2 directory index page from a local server: a SAXParseException with the message White spaces are required between publicId and systemId. The doctype looks ok to me, whitespace and all. When getting a page off a Drupal 7 generated site, it never finishes. The parse method seems to hang. No exceptions thrown, never returns. When getting http://www.oracle.com, a SAXParseException with the message The element type "meta" must be terminated by the matching end-tag "</meta>". So it would appear that the default setup I've used here doesn't handle HTML, only strictly written XML. My question is: can JAXP be used out-of-the-box from openJDK 7 to parse HTML from the wild (without insane gesticulations), or am I better off looking for an HTML 5 parser? PS this is for something I may not open-source, so licensing is also an issue :(

• SQL Server Snapshot Replication Subscriber (Editable or Read-Only)

  - by NateReid

  I need to create a copy of my SQL 2008 R2 Enterprise database and have it located on the same server as the original. I will be using this second copy of the database as the target of a mostly read-only website. I understand that if I create this copy of the database using snapshot replication that all data changes in the subscriber database will be overwriten in the event of the next replication. The web application will try to write to this database to record login attempts, etc and will fail if its source database is read-only. In my case I do not need to keep these auditing records and they can therefore be overwriten each time a new snapshot is applied. My question is whether SQL Server forces the subcriber database to be read-only and is there any way around this? Thank you, Nate

• Master-Details with RadGridView for Silverlight 4, WCF RIA Services RC2 and Entity Framework 4.0

  I have prepared a sample project with the Silverlight 4 version of RadGridView released yesterday. The sample project was created with Visual Studio 2010, WCF RIA Services RC 2 for Visual Studio 2010, and ADO.NET Entity Framework (.NET 4). I have decided to use the SalesOrderHeader and SalesOrderDetails tables from the Adventure Works Database, because they provide the perfect one-to-many relationship: I will not go over the steps for creating the ADO.NET Entity Data Model and the Domain Service Class. In case you are not familiar with them, you should start with Brad Abrams series of blog posts and read this blog after that. To enable the master-details relationship we need to modify two things. First of all we need to include the automatic retrieval of the child entities in the domain service class. We do this by using the Include method: 1: public IQueryable<SalesOrderHeader> GetSalesOrderHeaders()...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Change Gnome-Panel profile at startup according to number of displays

  - by ifischer

  I'm running Ubuntu 10.04 on a Laptop. I have a startup script which enables external displays, if they are connected. It runs at GDM startup, configured in /etc/gdm/Init/Default. When i'm running without external displays, Gnome should use 2 Panels. When i'm using 2 external displays, Gnome should add an additional Panel to the second display. But this should of course be removed again if i detach the external displays (and restart). Can i configure this use case by using Gnome Panel-profiles? I read that there is a startup option "--profile" for gnome-panel, but i don't know how and where i could switch the profile, especially because this has to be done after recognizing the number of displays. Or can i add a general Gnome profile and switch between those profiles somehow to achieve this behavior?

• arp problems with transparent bridge on linux

  - by Mink

  I've been trying to secure my virtual machines on my esx server by putting them behind a transparent bridge with 2 interfaces, one in front, one at the back. My intention is to put all the firewall rules in one place (instead of on each virtual server). I've been using as bridge a blank new virtual machine based on arch linux (but I suspect it doesn't matter which brand of linux it is). What I have is 2 virtual switchs (thus two Virtual Network, VN_front and VN_back), each with 2 types of ports (switched/separated or promiscious/where the machine can see all packets). On my bridge machine, I've set up 2 virtual NIC, one on VN_front, one on VN_back, both in promisc mode. I've created a bridge br0 with both NIC in it: brctl addbr br0 brctl stp br0 off brctl addif br0 front_if brctl addif br0 back_if Then brought them up: ifconfig front_if 0.0.0.0 promisc ifconfig back_if 0.0.0.0 promisc ifconfig br0 0.0.0.0 (I use promisc mode, because I'm not sure I can do without, thinking that maybe the packets don't reach the NICs) Then I took one of my virtual server sitting on VN_front, and plugged it to VN_back instead (that's the nifty use case I'm thinking about, being able to move my servers around just by changing the VN they are plugged into, without changing anything in the configuration). Then I looked into the macs "seen" by my addressless bridge using brctl showmacs br0 and it did show my server from both sides: I get something that looks like this : port no mac addr is local? ageing timer 2 00:0c:29:e1:54:75 no 9.27 1 00:0c:29:fd:86:0c no 9.27 2 00:50:56:90:05:86 no 73.38 1 00:50:56:90:05:88 no 0.10 2 00:50:56:90:05:8b yes 0.00 << FRONT VN 1 00:50:56:90:05:8c yes 0.00 << BACK VN 2 00:50:56:90:19:18 no 13.55 2 00:50:56:90:3c:cf no 13.57 the thing is that the server that are plugged in front/back are not shown on the correct port. I suspect some horrible thing happening in the ARP-world... :-/ If I ping from a front virtual server to a back virtual server, I can only see the back machine if that back machine pings something in the front. As soon as I stop the ping from the back machine, the ping from the front machine stops getting through... I've noticed that if the back machine pings, then its port on the bridge is the correct one... I've tried to play with the arp_ switch of /proc/sys, but with no clear effect on the end result... /proc/sys/net/ipv4/ip_forward doesn't seem to be of any use when using a bridge (seems it's all taken care of by brctl) /proc/sys/net/ipv4/conf//arp_ don't seem to change much either... (tried arp_announce to 2 or 8 - like suggested elsewhere - and arp_ignore to 0 or 1 ) All the examples I've seen have a different subnet on either side like 10.0.1.0/24 and 10.0.2.0/24... In my case I want 10.0.1.0/24 on both side (just like a transparent switch - except it's a hidden fw ). Turning stp on/off doesn't seem to have any impact on my issue. It's as if the arp packets where getting through the bridge, corrupting the other side with false data... I've tried to use the -arp on each interface, br0, front, back... it breaks the thing altogether... I suspect it has something to do with both side being on the same subnet... I've thought about putting all my machine behind the fw, so as to have all the same subnet at the back... but I'm stuck with my provider's gateway standing at the front with part of my subnet (in fact 3 appliance to route the whole subnet), so I'll always have ips from the same subnet on both side, whatever I do... (I'm using fixed front IPs on my delegated subnet). I'm at a loss... -_-'' Thx for your help. (As anyone tried something like this? from within ESXi?) (It's not just a stunt, the idea is to have something like fail2ban running on some servers, sending their banned IP to the bridge/fw so that it too could ban them - saving all the other servers from that same attacker in one go, allowing for some honeypot that would trigger the fw from any kind of suitable response, and stuffs of the sort... I am aware I could use something like snort, but it addresses some completely different kind of problems, in a completely different way... )

• Setting up Ubuntu Server on Amazon EC2 for hosting multiple domains with wildcard subdomains

  - by Ashish Kumar

  I'm trying to set up multiple domains on my Amazon EC2 micro instance running Ubuntu Server 12.04. I installed Apache correctly and set up virtual hosts but having problems with wildcard subdomains. This is what my httpd.conf file looks like NameVirtualHost *:80 <VirtualHost *:80> UseCanonicalName Off VirtualDocumentRoot /home/username/domains/%0/html/ </VirtualHost> My DNS records (on Amazon Route 53) are: domain.tld A 1.2.3.4 *.domain.tld A 1.2.3.4 If i create a test.domain.tld directory with the html subdirectory, it works fine. But what I want to do is to redirect *.domain.tld to domain.tld in case there is no directory for the sub-domain accessed. I would also like www.domain.tld to redirect to domain.tld. The system should also work if I decide to host another website, example.com, on the server. I tried Googling a lot but without any luck. Suggestions?

• Interactive Reporting with BI Publisher 11G

  - by kanichiro.nishida

  One of the new features that came out with BI Publisher 11G and made me really excited about is the Interactive Viewer, which allows you to interact with the data presented in the reports and gain more insights about the data. You can have as many Table, Chart, Pivot Table, Gauge components in a single report and all of them are linked together so that you can click on any data point on the components such as Chart, Pivot Table, Gauge, and that would refresh other components in the report to reflect the selection without refreshing the whole report or page. No longer you need to navigate to another report or open other reports to see related data or drill down to the detail data. It’s all there within a single report. Well, sounds cliché but really this is a typical case of ‘seeing is believing’, so instead of reading I would love you guys to take a look so I’ve recorded the following video. Please take a look !   The above video shows you the power of the BI Publisher Interactive Viewer with a real data from San Francisco Airport. The lists shown at the top or the left are one of the new features that we’ll be introducing in coming future very soon, but everything else is there with 11.1.1.3. So why not start today ? And please share your feedback with us!

• Using Umbraco&rsquo;s Dropdown Datatype

  - by MightyZot

  In Umbraco, you could consider document types like models and data types as property types for those modes. For example, you may create a document type called “Prices” to represent a page that displays a list of prices. And, then, you might create a document type called “Price Item” to represent the price list items. A property called “Price” could then represent the price of an item. When you create the Price property, you specify the data type, which in this case might be “Number”, indicating that this particular field accepts only numerical values. Consequently, you could also create a drop down list property called “Category”, allowing you to categorize the items in your price list. To add items to the drop down list, you modify the data type definition in the Developer module of the Umbraco administrative utility. Instead of modifying the drop down data type itself, you should first make a copy by right-clicking on the Data Types node and choosing Create. Give your new data type a name in the Create dialog and click the Create button. In the Edit datatype dialog, change “Render control” to “Dropdown list”.  To add your list items, simply enter that value into the textbox next to “Add prevalue” and click Save or press the Enter key. Now that you have a new drop down list data type created, along with assigned list items, you can use it in your document type definitions just like you would the other data types.

• LVS TCP connection timeouts - lingering connections

  - by Jon Topper

  I'm using keepalived to load-balance connections between a number of TCP servers. I don't expect it matters, but the service in this case is rabbitmq. I'm using NAT type balancing with weighted round-robin. A client connects to the server thus: [client]-----------[lvs]------------[real server] a b If a client connects to the LVS and remains idle, sending nothing on the socket, this eventually times out, according to timeouts set using ipvsadm --set. At this point, the connection marked 'a' above correctly disappears from the output of netstat -anp on the client, and from the output of ipvsadm -L -n -c on the lvs box. Connection 'b', however, remains ESTABLISHED according to netstat -anp on the real server box. Why is this? Can I force lvs to properly reset the connection to the real server?

• Auto-mount in fstab no longer working until manually running 'sudo mount -a'

  - by Brett Alton

  I have 3 SMB shared drives I need to connect to for work purposes. I had Ubuntu 10.10 Maverick and had all my drives loaded into fstab to be auto-mounted. Everything worked fine for a while but just before I upgraded to 11.04 Natty, the fstab auto-mount stopped working. Unfortunately I don't know what changed I made to my machine or what update installed that made this occur. /etc/fstab {snip} //192.168.7.3/apache_proj/ /home/brett/Desktop/apache smbfs guest,rw,iocharset=utf8,uid=1000,gid=1000 0 0 //192.168.7.3/apache_54321/ /home/brett/Desktop/54321 smbfs guest,rw,iocharset=utf8,uid=1000,gid=1000 0 0 //freenas.local/shared/ /home/brett/Desktop/shared smbfs guest,rw,iocharset=utf8,uid=1000,gid=1000 0 0 //lamp/www/ /home/brett/Desktop/lamp smbfs username={snip},password={snip},rw,iocharset=utf8,uid=1000,gid=1000 0 0 When the machine boots, I run this command to get them to mount: $ sudo umount /home/brett/Desktop/54321 /home/brett/Desktop/shared /home/brett/Desktop/apache; sudo mount -a [sudo] password for brett: umount: /home/brett/Desktop/54321: not mounted umount: /home/brett/Desktop/shared: not mounted umount: /home/brett/Desktop/apache: not mounted Warning: mapping 'guest' to 'guest,sec=none' Warning: mapping 'guest' to 'guest,sec=none' Warning: mapping 'guest' to 'guest,sec=none' mount error: could not resolve address for lamp: No address associated with hostname (I run that umount as a just-in-case).

• Project Manager that wants to lock in time estimate with a signed contract

  - by sunpech

  At a previous employment, a project manager (PM) wasn't satisfied with the delivery time of the code on a project I was on. I was told by my project lead that that the PM was considering having me sign a contract to lock-in my time estimates I gave for tasks and delivery dates. The situation on the project was that we were working with new technologies, codebase, coding standards, and very prone-to-change requirements. I was learning new things and applying them the best I could on requirements that kept on changing. The requirements throughout the iterations grew by 2-3 times, with my estimate-to-complete growing by roughly 5-8 times. The only things that didn't change were the estimates and delivery dates. Yes, I did end up missing most deadlines. And I was working on some very new technologies that no one else on the entire development team could really help out on because they wouldn't be familiar with it. At least not easily. It seemed to me then, that the PM wanted his numbers to add up-- and thus wanted me to sign a contract to "ensure" that I would always deliver working code on time. I suppose with a signed contract the PM could use it against me if I couldn't deliver on time. I believe what happened next was that other project managers and/or project leads defended me, and didn't let this happen. My question is, should this raise a red flag about the manager? Is it common practice for a manager to lock-in time estimates of a software developer with a signed contract? Or in this case, try to. Please note, I was a full time employee, not an independent consultant. Update: I want to add that I did give new estimates weekly, but it seems the original estimates and delivery dates were what the PM was fixated on.

• How can I stop sysprep from interacting with boot on windows 7

  - by Grofit

  I have recently had a laptop sent back to supplier for fixing a mainboard fault. I got it back today and every time it boots up I am faced with: "Setup is preparing windows for first time use" Then once it gets to the desktop I get the sysprep dialog come up asking if I want OOBC or Audit actions. I can close it, but it just keeps coming back, and I cannot find any startup or boot actions, even downloaded autoruns, and that cannot find anything to do with it. Ideally I do not want to format/fdisk as I have just spent hours installing everything on the laptop and I have my primary C:/ which has all windows and at worst case I can get rid of that, but I have a secondary partition D:/ which has alot of stuff I cant lose as its work related and important. Also to make matters more difficult I do not have a windows 7 disk, it was just pre-installed and they dont provide a disk. Any help would be great!

• Mapping drives on MacOSX (Leopard/Snow Leopard) permanently inside LAN

  - by Shyam

  Hi, How do I "map" shared folders on a Mac, permanently? With map, I do not mean 'connect', but permanently add it to the system so it exists after reboot. Since workstations tend to shutdown, I wonder also the symptoms and cures in case that happens. In Linux, this can be done using the fstab file, but I noticed that volumes are mounted in a different structure than Linux. I need this to backup some workstations, doing a recursive job over a single directory, that should contain the shared folders. I use Terminal to access the main system, so by preference, the solution would be nice that works within a bash shell vs GUI. I can access all folders in Finder. Thanks!

• How to ...set up new Java environment - largely interfaces...

  - by Chris Kimpton

  Hi, Looks like I need to setup a new Java environment for some interfaces we need to build. Say our system is X and we need to interfaces to systems A, B and C. Then we will be writing interfaces X-A, X-B, X-C. Our system has a bus within it, so the publishing on our side will be to the bus and the interface processes will be taking from the bus and mapping to the destination system. Its for a vendor based system - so most of the core code we can't touch. Currently thinking we will have several processes, one per interface we need to do. The question is how to structure things. Several of the APIs we need to work with are Java based. We could go EJB, but prefer to keep it simple, one process per interface, so that we can restart them individually. Similarly SOA seems overkill, although I am probably mixing my thoughts about implementations of it compared to the concepts behind it... Currently thinking that something Spring based is the way to go. In true, "leverage a new tech if possible"-style, I am thinking maybe we can shoe horn some jruby into this, perhaps to make the APIs more readable, perhaps event-machine-like and to make the interface code more business-friendly, perhaps even storing the mapping code in the DB, as ruby snippets that get mixed in... but thats an aside... So, any comments/thoughts on the Spring approach - anything more up-to-date/relevant these days. EDIT: Looking a JRuby further, I am tempted to write it fully in JRuby... in which case do we need any frameworks at all, perhaps some gems to make things clearer... Thanks in advance, Chris

• Architecting Python application consisting of many small scripts

  - by Duke Dougal

  I am building an application which, at the moment, consists of many small Python scripts. Each Python script processes items from one Amazon SQS queue. Emails come into an initial queue and are processed by a script and typically the script will do a small unit of processing (for example, parse email and store some database fields), then an item will be placed on the next queue for further processing, until eventually the email has finished going through the various scripts and queues. What I like about this approach is that it is very loosely coupled. However, I'm not sure how I should implement live. Should I make each script a daemon which is constantly polling it's inbound queue for things to do? Or should there be some overarching orchestration program or process? Or maybe I should not have lots of small Python scripts but one large application? Specific questions: How should I run each of these scripts - as a daemon with some sort or restart monitor to restart them in case they stop for any reason? If yes, should I have some program which orchestrates this? Or is the idea of many small script not a good one, would it make more sense to have a larger python program which contains all the functionality and does all the queue polling and execution of functionality for each queue? What is the current preferred approach to daemonising Python scripts? Broadly I would welcome any comments or opinions on any aspect of this. thanks

• Have SSIS' differing type systems ever caused you problems?

  - by jamiet

  One thing that has always infuriated me about SSIS is the fact that every package has three different type systems; to give you an idea of what I am talking about consider the following: The SSIS dataflow's type system is made up of types called DT_*  (e.g. DT_STR, DT_I4) The SSIS variable type system is based on .Net datatypes (e.g. String, Int32) The types available for Execute SQL Task's parameters are based on something else - I don't exactly know what (e.g. VARCHAR, LONG) Speaking euphemistically ... this is not an optimum situation (were I not speaking euphemistically I would be a lot ruder) and hence I have submitted a suggestion to Connect at [SSIS] Consolidate three type systems into one requesting that it be remedied. This accompanying blog post is not however a request for votes (though that would be nice); the reason is actually subtler than that. Let me explain. I have been submitting bugs and suggestions pertaining to SSIS for years and have, so far, submitted over 200 Connect items. If that experience has taught me anything it is this - Connect items are not generally actioned because they are considered "nice to have". No, SSIS Connect items get actioned because they cause customers grief and if I am perfectly honest I must admit that, other than being a bit gnarly, SSIS' three type system architecture has never knowingly caused me any significant problems. The reason for this blog post is to ask if any reader out there has ever encountered any problems on account of SSIS' three type systems or have you, like me, never found them to be a problem? Errors or performance degredation caused by implicit type conversions would, I believe, present a strong case for getting this situation remedied in a future version of SSIS so if you HAVE encountered such problems I would encourage you to leave a comment on the Connect submission accordingly. Let me know in the comments too - I would be interested to hear others' opinions on this. @Jamiet
