• Android: setting up a google map class. bit of advice required.

  - by Capsud

  Hey there, Ok so this is what i've got. Button anandabutton = (Button) findViewById(R.id.anandaAddressButton); anandabutton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Intent myIntent = new Intent(view.getContext(),MapClass.class); startActivityForResult(myIntent,0); } }); This method opens up my MapClass class which at the moment I just have set to show the location of one place. But I have a load of buttons and rather than making a lot of different mapClass classes for each button, I am wondering can I just use the one class and depending on what button 'id' is pressed, it will check an 'if statement' and then put in the correct coordinates into the method to display the map. It would be a lot neater than coding up like 20-30 classes. I'm not sure if i've explained that right so if not let me know. Thanks for any help.

• Model in sub-directory via app_label?

  - by prometheus

  In order to place my models in sub-folders I tried to use the app_label Meta field as described here. My directory structure looks like this: project apps foo models _init_.py bar_model.py In bar_model.py I define my Model like this: from django.db import models class SomeModel(models.Model): field = models.TextField() class Meta: app_label = "foo" I can successfully import the model like so: from apps.foo.models.bar_model import SomeModel However, running: ./manage.py syncdb does not create the table for the model. In verbose mode I do see, however, that the app "foo" is properly recognized (it's in INSTALLED_APPS in settings.py). Moving the model to models.py under foo does work. Is there some specific convention not documented with app_label or with the whole mechanism that prevents this model structure from being recognized by syncdb?

• What technologies are appropriate for a human workflow system?

  - by CCw

  I'm researching various workflow architectures and it is overwhelming. The workflow system I am creating will be almost completely human-driven. Very little, if any, asynchronous activity will be taking place. One possibility is to simply use a RDBMS and have a task table, from which stored procedures would be used to enforce synchronous access to each task. This seems very simple, but I'm having a hard time coming up with reasons why I might need to involve a heavier solution. If my system has ~500 concurrent users, and there is very little in the way of automated or asynchronous tasks, should I even consider the various workflow patterns/packages out there like Mule, BPEL/SOA, Spring Work Flow, etc?

• Doctrine SQL Server uniqueidentifier isn't cast as char or nvarchar when retrieved from the database

  - by Tres

  When I retrieve a record from the database which has a column of type "uniqueidentifier", Doctrine fills it with "null" rather than the unique id from the database. Some research and testing has brought this down to a PDO/dblib driver issue. When directly querying via PDO, null is returned in place of the unique id. For reference, http://trac.doctrine-project.org/ticket/1096, has a bit on this, however, it was updated 11 months ago with no comment for resolution. A way around this, as mentioned at http://bugs.php.net/bug.php?id=24752&edit=1, is to cast the column as a char. However, it doesn't seem Doctrine exposes the native field type outside of generating models which makes it a bit hard to detect uniqueidentifier types and cast them internally when building the sql query. Has anyone found a workaround for this?

• Avoiding configSections in .NET app.config files

  - by Chris Clark

  I'm looking for a way to avoid declaring my configuration section in the configSections inside the App.config file. Basically, I want to specify my configuration information just like I do for built-in .NET systems. For instance, when configuring WCF, I just put stuff in the <system.serviceModel>, I don't have to declare a section in the configSections up top. The same thing applies for <system.diagnostics> and many other namespaces. I know I could just load it up as an XML file and parse through it, but I'd prefer to stick with the pattern if possible. Moreover, looking at the WCF configuration with Reflector, I notice that it uses the same configuration subsystem (defined in System.Configuration). If you're wondering why this is important, it's because it's confusing our IT people. If it were self contained in one place, it would be much easier on them. I also realize I'll lose the ability to have multiple of the same section type, but that's not important in our case.

• Really basic Django E-commerce? Where do I start

  - by Andrew

  I'm trying to set up a really basic e-commerce site with Django, and am trying to figure out the best place to start. I am relatively comfortable with the framework itself, but have never done any sort of e-commerce development in any language, so I want to learn about some best practices so I don't make any huge or obvious mistakes. I've looked at Satchmo, and even went as far as installing and playing around with it, but it looks like way more than I want. I basically want to show users a list of things, and let them click a button to buy one. No cart, no shipping, just click a button, connect with Authorize.net (or something similar) to do the transaction, and then display a confirmation page. Any suggestions or online tutorials people have found helpful? Even perhaps a tutorial in another language. Or maybe a really lightweight Django plugin that doesn't try to do everything like Satchmo? I've been coming up with very little so far. Thanks!

• Using the filename for GET data and making the PHP page output as a JPG extension?

  - by Rob

  Alright, currently I'm using GD to create a PNG image that logs a few different things, depending on the GET data, for example: http://example.com/file.php?do=this will log one thing while http://example.com/file.php?do=that will log another thing. However, I'd like to do it without GET data, so instead http://example.com/dothis.php will log one thing, and http://example.com/dothat.php will log the other. But on top of that, I'd also like to make it accessible via the JPG file extension. I've seen this done but I can't figure out how. So that way http://example.com/dothis.JPG will log one thing, while http://example.com/dothat.JPG logs the other. The logging part is simple, of course. I simple need to know how to use filenames in place of the GET data and how to set the php file to be accessible via a jpg file extension.

• emacs: is there a semantic-jump-to-declaration (using semantic.el)?

  - by Cheeso

  Suppose I am editing a buffer containing C code. I have started semantic with semantic-load-enable-code-helpers . I have point placed on the name of a function . If I then invoke senator-jump I can jump to the place where that fn is first declared, in that module. What if it is an extern? Is it possible to use senator to jump to the definition of the fn, which resides in a separate module? Thanks.

• Programatically opening an xml file in MS Word

  - by Dan Revell

  I'm opening an xml file in Microsoft Word 2007 using C#. I'm using an xsl file to define the layout which worked up to the point that I needed to include an image. I used the typical src html tag and the image displays when the xml is viewed in ie but not when it's opened in Word. I get the image place holder so I can only assume Word simply can't find the image. It's sitting next to both the xml file and xsl file but that doesn't make any difference. To open the document I'm passing the filenames for both the xml and xsl. I would imagine that as the src is in the xsl it would just look relative to one of these files. Any suggestions would be much appreciated. [EDIT] Apologies I lost track of this one. I fixed it in the end. I'll check what my solution was tomorrow and update this.

• Html how to make a part on iframe, unvisible and unclickable externally? (my idea)

  - by ozan

  I have a page (A) including a BUTTON with a function close_window() , however when I embed A to my main page (B) using iframe, the close_window() can't work as expected since there is no more window anymore, and I am not able to remove the button from the iframe since A is on another domain (Security issues prevents). What I want to do is make this button label invisible. And the only way I think is to put a white image just to the place where that button exists on my iframe, externally. is Smthing like that possible? I want the image to be on the top of iframe? Or do you have any other idea ? Thanks for helps.

• Setting a Global Doctype

  - by Batfan

  Is it possible using PHP (I was thinking may the phpinfo file or a php.ini file) or an .htaccess file to set a doctype for an entire subdirectory? Basically, in a nutshell, I'm using a software that uses XSL templates to output data to a set of HTML files. Modifying the xsl:output tag to include the doctype breaks the template and therefore, does not work. Just adding the doctype in the XSL file, breaks it as well. I need the proper doctypes in place for my CSS to function properly, cross-browser. I realize that I could add the doctype to the HTML files after export but, I'm really striving to automate this process. Any thoughts?

• How would I go about writing a Linux TTY sniffer?

  - by alienate

  For educational purposes (not that anyone should care the motivations behind such an exercise) I'd like to write a program that can read/write to/from alternate tty/pty's. I've read papers (from the 1990's) but can't employ the implementation they use, on modern UNIXes. I was hoping that someone had researched into this in the past, or at least, read documentation pertaining to it, that they could provide. I also wonder if (considering the fact that Linux doesn't have STREAMs) if this exercise must be done via a loadable kernel module? I have many questions and probably a misunderstanding of some of the fundamental ideologies that allow such objectives to be put in place, could someone help? :)

• Routing with VPN and asymmetric communication

  - by Louis

  I'm stumbling on a problem that requires your advice. Keywords : networking, route, openVPN Problem : I have a local network with several physical servers and VMs. These machines have ip's in the range 10.10.x.x. I can access these machines from the Internet with the help of openVPN. These machines can : access each other within the local 10.10.x.x subnet access the Internet via the VPN can themselves be accessed (via SSH) from the Internet via the VPN. There is one machine however that behaves strangely and I don't know why. I can SSH into this machine from anywhere via SSH and I can also PING it from anywhere (including the Internet). However from this machine (i.e. when logged into it) I cannot access the Internet or ping machines outside the local network. In other words it will not go beyond the VPN. My question is why? Here are some technical details: The machine's Network Config (running Debian 6.0.3): allow-hotplug eth0 iface eth0 inet static address 10.10.10.200 netmask 255.255.0.0 network 10.10.10.0 broadcast 10.10.10.255 gateway 10.10.10.200 The machine's Routing : Destination Gateway Genmask Flags MSS Window irtt Iface 127.0.0.1 0.0.0.0 255.255.255.255 UH 0 0 0 lo 10.10.0.0 10.10.10.250 255.255.0.0 UG 0 0 0 eth0 10.10.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 0.0.0.0 10.10.10.250 0.0.0.0 UG 0 0 0 eth0 0.0.0.0 10.10.10.200 0.0.0.0 UG 0 0 0 eth0 The VPN's Network Config (running Debian 6.0.3): # This is the local network interface auto eth1 allow-hotplug eth1 iface eth1 inet static address 10.10.10.250 netmask 255.255.0.0 broadcast 10.10.10.255 gateway 10.10.10.250 The VPN's routing table Destination Gateway Genmask Flags MSS Window irtt Iface 10.10.0.0 0.0.0.0 255.255.255.0 U 0 0 0 tun0 private 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.10.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 0.0.0.0 10.10.10.250 0.0.0.0 UG 0 0 0 eth1 0.0.0.0 private 0.0.0.0 UG 0 0 0 eth0 net.ipv4.ip_forward = 1 on both machines. there are no iptables set anywhere.

• CI Build status output alternatives

  - by Brett Rigby

  We currently use Cradiator to display the status of our continuous integration (CI) builds from CruseControl.net, on a 42" Samsung television on display high-up in our IT department. Cradiator is a great starting place, but we're getting to the point whereby we're having lots of projects on there and it's starting to get a bit 'full'. What I'd like to know is, what do you use to display your build statuses? Custom software? Off the shelf stuff? etc. Alternatively, I'm looking for ideas on how we improve on Cradiator.

• keyboard in UIWebView shows and then hides itself on input focus

  - by Jake

  I have a page that's loading into a UIWebView (which takes 100% of the screen) on an iPad. When I touch a text field, the page positions the text field to the right place and the keyboard starts to come up, but then it turns around and goes back down and blur is called on the input field. When I try this same page in mobile Safari, the keyboard is able to deploy successfully. I can't figure out what the rules are for the keyboard to show successfully and stay up = and why this is different for uiwebview than safari. All my research on the subject has yielded no answers.

• iotop for Linux kernel 2.6.18

  - by Lightsauce

  So it has to come to my attention that iotop isn't availalbe for 2.6.18 since it's less than 2.6.20 and requires Python 2.6+. I've done some research and came across this article: http://lserinol.blogspot.com/2009/09/io-usage-per-process-on-linux.html According to this, if these process have io stats in /proc/pid#/io (where pid# is the process #) it's doable regardless of the kernel version. So, in reality, I could upgrade Python to 2.6 and test out iotop. However, my flavor of Linux, CentOS release 5.5 (Final), only supports Python 2.4.3-44.el5 currently. If I were to do uninstall from yum, it doesn't look so pretty. It ends up wanting to uninstall 235 packages, most of which are very important! I read in one place, online (I forget the URL from yesterday), that you can install Python 2.6+ parallel to this one, and have the rpm install for iotop use that. Well, I didn't choose that route. I figured, what the heck, lets write iotop (not copying it, but reverse engineering it without actually looking at it's code/it in use) in bash. I thought it would just grab the /proc/pid#/io file and parse stats. So I wrote a script to grab the top 10 rchar, wchar, read_bytes, and write_bytes by collecting all these stats from all the /proc/pid#/io files, sorting them by each metric, then grabbing the top 10 highest values. The conclusion, the data seems completely useless. Does anybody know any resources for advanced Linux where I can figure out how to take these /proc/pid#/ directories and figure out what the heck they are doing with io on the disk? My main goal is to figure out what exactly is causing high load on my disk. I just know it's on the / partition (/dev/sda2 in this case), and I'm not really sure how to narrow it down without the help of iotop. If I run iostat to grab metrics for 1 minute, every second, the first result it gives me shows a high 'kB_read/s', so that makes me think, it's reading mostly. However, if I watch the update it gives me every second, it's actually just showing values for kB_wrtn/s. This makes me think the initial value iostat gives me is misleading.

• Python in AWS Elastic Beasntalk: Private package dependencies

  - by Adam Matan

  I would like to deploy a Python Flask application on beanstalk. The application depends on external packages (e.g. geopy) and internal packages (e.g. adam_geography). The manual Create a requirements.txt file and place it in the top-level directory of your source bundle. This would probably fetch geopy and its dependencies, but would not fetch adam_geography which is available from a custom repo inside my VPC. How do I specify/upload private, internal Python package dependencies in a Beanstalk application?

• Awk appears to disconnect my DB2 session when piping

  - by greggannicott

  Hello. I'm attempting to run the following command in Korn Shell (ksh): set -A INDEXES `db2 "describe indexes for table ${TABSCHEMA}.${TABNAME} show detail" | awk '{print $1"."$2}'` What I'm attempting to achieve is place a list of the indexes over a particular table into an array which I can later iterate through. The problem is, when I run the above command the contents of the array starts with the error message of 'SQL1024N' (which is telling me that the database connection does not exist). However, if I remove the 'awk' at the end of the statement as so: set -A INDEXES `db2 "describe indexes for table ${TABSCHEMA}.${TABNAME} show detail"` it works just fine (well, to the extent its returning data. Obviously without the awk I'm not capturing the correct data). Does anyone know why the awk is having this affect? I appreciate there is more than one way to get this data, but it baffles me as to why this is happening. Thanks in advance. Greg.

• performing auditing in java with sql server DB - before and/or after do not get audited

  - by Domingos

  When auditing, sometimes the before value does not get audited, other times the after value does not get audited, other times both values do not get audited at all. After researching, I found out that only values from a specific codes table get audited. the code was: compareCodesTableInteger(audit, int, int, objectBefore, objectAfter, stringDescription, stringCodesTable); I then changed it to: compareCodesTableInteger(audit, int, int, objectBefore, objectAfter, stringDescription, booleanCheck ? stringCodesTableIfTrue : stringCodesTableIfFalse); Description: if objectBefore AND objectAfter are both from stringCodesTableIfTrue OR from stringCodesTableIfFalse, auditing takes place as expected. The problem is: most of the times, objectBefore is from stringCodesTableIfTrue, and objectAfter is from stringCodesTableIfFalse, or vice-versa. In this scenario auditing fails. How do I go around this? Please assist

• Reload table view in real time

  - by Lucas Vallim da Costa

  The app receives a UILocalNotification, but if the user is at the UITableViewController at the fire time, the table view (containing the scheduled notifications) does not reload. The user has to get out of that view and load the view again so that the cells are loaded and, as the notification was already fired, it will not be displayed on any cell of that table view. Problem is: If the user touches the specific tableView cell that contained the notification that just fired, the app crashes, cause the notification is not there anymore. I've implemented the - (void)reloadData in every place possible, and it still doesn't load in real time. What would be a better solution for this? Other detail, how can I push a specific view after the notification is displayed (when the user slides the app icon when the phone is locked)? Any help will be truly appreciated, since theres are the last details remaining to publish my first App.

  A small initiative from my work place plans to teach very basic computers to not so fortunate kids. I was looking for some very basic topics/resources. These kids are very young and have not seen/worked with a computer before. The fun factor should not be lost and hence I don't want it to be rigorous, just plain, what is computer, keyboard, mouse, browser, where to look for what (google.com) and so on. Has any-one done this sort of thing before, if yes, could you point me to some resources.

• Developing a very nonstandard Drupal form

  I'm creating a site for a local retail shop using Drupal. Everything's been going very smoothly up until this current bit. It's a comic shop, and I want to make a place where people can manage their own subscriptions. Since the number of different titles a customer subscribes to can vary pretty widely, I want a way to make a completely dynamic form, with people able to add as many new lines as they need and I'm really struggling with Drupal's documentation. Essentially, I'd like the final version of the page to look something like this: http://www.monksp.org/foo.html Anyone have any experience building a drupal form like this?
