• Java applet icon doesn't show

  - by user295744

  I have a java applet where I've changed the image icon that appears in the top left corner of the window. The code I use is this: Toolkit kit = Toolkit.getDefaultToolkit(); Image frameIcon = kit.getImage("src/myapp/resources/logo.png"); getFrame().setIconImage(frameIcon); Everything works fine until I deploy the applet to a standalone jar. In this case the icon that shows is the default icon, as if the code couldn't find the image. But the image is inside, although it is in the folder: myapp/resources/ What am I doing wrong here? Is this some weird java bug?

• Why does this bash command take up all space on device?

  - by chelmertz

  Hey! I'm a little new on searching via bash, so feel free to give me suggestions on the methods to use instead of this, which I'll never use again :) I'm searching for occurances of a string, recursively in a directory, with ~50 not-that-large php-files in it; some in current directory, some in directories beneath current dir, three levels of directories down at most. The method I'm using is: find . | xargs grep "module" > module.txt When in simple (one level) directories, this works fine, but in this case, the file became 4 GB large until it filled up all space on the partition :) It wasn't even done yet.. Would someone educate me so I won't embarass myself again?

• Serialize Dictionary with a string key and List[] value to JSON

  - by Patrick

  How can I serialize a python Dictionary to JSON and pass back to javascript, which contains a string key, while the value is a List (i.e. []) if request.is_ajax() and request.method == 'GET': groupSet = GroupSet.objects.get(id=int(request.GET["groupSetId"])) groups = groupSet.groups.all() group_items = [] #list groups_and_items = {} #dictionary for group in groups: group_items.extend([group_item for group_item in group.group_items.all()]) #use group as Key name and group_items (LIST) as the value groups_and_items[group] = group_items data = serializers.serialize("json", groups_and_items) return HttpResponse(data, mimetype="application/json") the result: [{"pk": 5, "model": "myApp.group", "fields": {"name": "\u6fb4\u9584", "group_items": [13]}}] while the group_items should have many group_item and each group_item should have "name", rather than only the Id, in this case the Id is 13. I need to serialize the group name, as well as the group_item's Id and name as JSON and pass back to javascript. I am new to Python and Django, please advice me if you have a better way to do this, appreciate. Thank you so much. :)

• Why TortoiseHg not show the "merge conflict"?

  - by Jian Lin

  Short version of the question: Since I already have TortoiseHg, I right clicked on that file trying to see the merge conflict visually, but there is no way to see it? Details: To make a simple case of merge conflict, I hg init a repo on Win 7, and then clone it to another folder. Now, in one working directory, i added the line "the code is 123", committed. And in the other folder, i did an "hg pull" and "hg update" Now, I go back to the first folder, and change "123" to "123abc", and then do an "hg commit" And then I go to the other folder and edit "123" to "123xyz" over there, and do an "hg commit", and when "hg push", it says it can't. So I try to use any visual tool to see how the conflict is like, but ... TortoiseHg doesn't seem to have any option to do that?

• Comments on this assumption about running on dev server vs a real instance in app engine (python)?

  - by Jacob Oscarson

  Hello app engineers! I'm on an app engine project where I'd like to put in a link to a Javascript test runner that I'd like to only exist when running the development server. I've made some experiments on a local shell with configuration loaded using the technique found in NoseGAE versus live on the 'App Engine Console' [1] and it looks to me like a distinction btw real instance and dev server is the presence of the module google.appengine.tools. Which lead me to this utility function: def is_dev(): """ Tells us if we're running under the development server or not. :return: ``True`` if the code is running under the development server. """ try: from google.appengine import tools return True except ImportError: return False The question (finally!) would be: is this a bad idea? And in that case, can anyone suggest a better approach? [1] http://con.appspot.com/console/ (try it! very handy indeed)

• php multidimensional array problem

  - by ntan

  Hi to all, i am trying to setup a multidimensional array but my problem is that i can not get the right order from incoming data. Explain $x[1][11]=11; $x[1]=1; var_dump($x); In the above code i get only x[1]. To right would be $x[1]=1; $x[1][11]=11; var_dump($x); But in my case i can dot ensure that x[1] will come first, and x[1][11] will come after. Is there any way that i can use the first example and get right the array. Keep in mind that the array depth is large. Thats

• 3D line plane intersection, with simple plane

  - by clamp

  hello, i have two points in 3D space which have X-coordinates with different signum. so one of them lies definitely on one side of the X-plane and one on the other. now i want to find the intersection of this plane and the line made up by the two points in the most simple and optimized way. i know how to do general line plane intersection, but since in this case the plane is just the x-plane, i think there should be some shortcuts i can take. thanks!

• Output of System.out.println(object)

  - by Shaarad Dalvi

  I want to know what exactly the output tells when I do the following : class data { int a=5; } class main { public static void main(String[] args) { data dObj=new data(); System.out.println(dObj); } } I know it gives something related to object as the output in my case is data@1ae73783. I guess the '1ae73783' is a hex number. I also did some work around and printed System.out.println(dObj.hashCode()); I got number 415360643. I got an integer value. I don't know what hashCode() returns, still out of curiosity, when I converted 1ae73783 to decimal, I got 415360643! That's why I am curious that what exactly is this number?? Is this some memory location of Java's sandbox or some other thing? Any light on this matter will be helpful..thanks! :)

• How to edit default.aspx on SharePoint site without SharePoint Designer

  - by Magnus Johansson

  On several occations, I have faced the situation that the default.aspx page on a Site doesn't work. More specifically, a reference to a WebPart and/or Control is throwing a error because the assembly is not found. Fine, you just fire up the dreaded SharePoint Designer and remove the dependency line. However, if I wanted to use this method when not having SharePoint Designer, how could this be done? EDIT: Removing the web part using the "?contents=1" web part management page didn't help in my case. The <%@Register tag was still there and had to be removed using SharePoint Designer.

• How to add a suffix at the end of a string in PHP

  - by Golem

  I am trying to add a .html suffix at the end of all strings supplied by the user before it is entered into the database. Here's my code so far: strtolower(str_replace(" ", "_", $postTitle)); The above takes the title of the post the user it trying to make, turns it to lower case, replaces all white spaces with underscores and makes it ready to be entered into a database column called post_url. I just need it to do one more thing and that's to add a .html at the end of each post url. What is the function to do this?

• How do I view Visual Studio BuildLog.htm files without cutting and pasting into an external browser

  - by bgoodr

  This may or may not be specific to VS2005 (as that is the version I'm referring to for this question). I find often the case is that I see this in the Output panel inside Visual Studio 2>Build log was saved at "file://c:\\vsdll_example\MyExecRefsDll\Debug\BuildLog.htm" Now, since that looks and smells like a URL, I would have thought that I could simply left mouse click on it, or left mouse double-click on it, and a browser window of some sort would be displayed. No, that doesn't work. So, to view it, I have to cut and paste the "file://bla/bla/bla" part into an external window. Is there a way to set up Visual Studio to allow me to browse to that file directly, or view it inside Visual Studio IDE, or something to that effect, without the extra fiddling with cutting and pasting? Or is there some type of keybinding I'm not aware of? Thanks, bg

• Why does tokyo tyrant slow down exponentially even after adjusting bnum?

  - by HenryL

  Has anyone successfully used Tokyo Cabinet / Tokyo Tyrant with large datasets? I am trying to upload a subgraph of the Wikipedia datasource. After hitting about 30 million records, I get exponential slow down. This occurs with both the HDB and BDB databases. I adjusted bnum to 2-4x the expected number of records for the HDB case with only a slight speed up. I also set xmsiz to 1GB or so but ultimately I still hit a wall. It seems that Tokyo Tyrant is basically an in memory database and after you exceed the xmsiz or your RAM, you get a barely usable database. Has anyone else encountered this problem before? Were you able to solve it?

• Is the ruby operator ||= intelligent?

  - by brad

  I have a question regarding the ||= statement in ruby and this is of particular interest to me as I'm using it to write to memcache. What I'm wondering is, does ||= check the receiver first to see if it's set before calling that setter, or is it literally an alias to x = x || y This wouldn't really matter in the case of a normal variable but using something like: CACHE[:some_key] ||= "Some String" could possibly do a memcache write which is more expensive than a simple variable set. I couldn't find anything about ||= in the ruby api oddly enough so I haven't been able to answer this myself. Of course I know that: CACHE[:some_key] = "Some String" if CACHE[:some_key].nil? would achieve this, I'm just looking for the most terse syntax.

• How Likely Is It That I'll Get Sued Developing Software?

  - by yar

  It has been a practically unanimous truth on StackOverflow that if you work as an independent consultant, you should probably form a corporation (as seen here), to limit personal liability, supposedly to protect you in case of lawsuit. It seems to me that developing software does not result in many lawsuits, but this is an empirical (objective [and not community wiki]) question: How likely is it that a lone software developer will be sued? Also, by whom (a disgruntled company, coworker)? Since incorporating is basically taking out insurance, the likelihood of catastrophe needs to be taken into account. Also, aren't there standard laws covering, for example, total screw-ups with corporate data that mean that protect the lone cowboy/girl/person/coder?

• Does normalization really hurt performance in high traffic sites?

  - by Luke101

  I am designing a database and I would like to normalize the database. I one query I will joining about 30-40 tables. Will this hurt the website performance if it ever becomes extremely popular? This will be the main query and it will be getting called 50% of the time. The other queries I will be joining about 2 tables. I have a choice right now to normalize or not to normalize but if the normalization becomes a problem in the future i may have to rewrite 40% of the software and it may take me a long time. Does normalization really hurt in this case? Should I denormalize now while I have the time?

• Writing WCF messages to a text log in configurable directory.

  - by Arsh

  Hello everyone, I have a WCF web service that is deployed at IIS. Part of the web service is to validate the inputs using EntLib 4.1 For ex, the string values can be of specific length and so on. In case of the validation being failed a fault exception is raised and the service is supposed to write the message in log file. How do I go about creating the log file to a location that can be configured from a config file. Basically how do we write messages from IIS (since the service is hosted at IIS, I am assuming that that will be the source !!!!) Regards.

• Pattern or recommneded refactoring for method

  - by iKode

  I've written a method that looks like this: public TimeSlotList processTimeSlots (DateTime startDT, DateTime endDT, string bookingType, IList<Booking> normalBookings, GCalBookings GCalBookings, List<DateTime> otherApiBookings) { { ..... common process code ...... while (utcTimeSlotStart < endDT) { if (bookingType == "x") { //process normal bookings using IList<Booking> normalBookings } else if (bookingType == "y") { //process google call bookings using GCalBookings GCalBookings } else if (bookingType == "z" { //process other apibookings using List<DateTime> otherApiBookings } } } So I'm calling this from 3 different places, each time passing a different booking type, and each case passing the bookings I'm interested in processing, as well as 2 empty objects that aren't used for this booking type. I'm not able to get bookings all into the same datatype, which would make this easier and each booking type needs to be processed differently, so I'm not sure how I can improve this. Any ideas?

• Two parallel line segments intersection

  - by Judarkness

  I know there are many algorithms to verify whether two line segments are intersected. But once they encountered parallel condition, they just tell the user a big "No" and pretend there is no overlap, share end point, or end point collusion. I know I can can calculate the distance between 2 lines segments. If the distance is 0, check the end points located in the other line segments or not. And this means I have to use a lot of if else and && || conditions. This is not difficult, but my question is "Is there a trick( or mathematics) method to calculate this special parallel case?"

• Uniform distribution of binary values in Matlab

  - by JohnIdol

  I have a requirement for the generation of a given number N of vectors of given size each consistent of a uniform distribution of 0s and 1s. This is what I am doing at the moment, but I noticed that the distribution is strongly peaked at half 1s and half 0s, which is no good for what I am doing: a = randint(1, sizeOfVector, [0 1]); The unifrnd function looks promising for what I need, but I can't manage to understand how to output a binary vector of that size. Is it the case that I can use the unifrnd function (and if so how would be appreciated!) or can is there any other more convenient way to obtain such a set of vectors? Any help appreciated!

• How to get the list of files in a directory in a shell script?

  - by jrharshath

  Hi, I'm trying to get the contents of a directory using shell script. My script is: for entry in `ls $search_dir`; do echo $entry done where $search_dir is a relative path. However, $search_dir contains many files with whitespaces in their names. In that case, this script does not run as expected. I know I could use for entry in *, but that would only work for my current directory. I know I can change to that directory, use for entry in * then change back, but my particular situation prevents me from doing that. I have two relative paths $search_dir and $work_dir, and I have to work on both simultaneously, reading them creating/deleting files in them etc. So what do I do now? PS: I use bash.

• Android: Get the screen resolution / pixels as integer values

  Hi guys, this is a really simple question on which I've found no answer :/ How can I quickly access the screen resolution (width, height) as integer values? I've tried this one, but it always shows zero on my emulator: DisplayMetrics dm = new DisplayMetrics(); int width = dm.widthPixels / 2; In my case I want to dynamically create a table with tableRows, each containing two cols. This cols all shall fill half of the screen in width. Can someone give me a hint?

• How to get Anchor text using DomDocument?

  - by Click Upvote

  Say I have this html: <a href="http://example.com">Test</a> I parse it using dom document with this code: $dom = new DomDocument(); @$dom->loadHTML($html); $urls = $dom->getElementsByTagName('a'); And then I run this code: foreach ($urls as $url) { //echo "<br> {$url->getAttribute('href')} , {$url->getAttribute('title')}"; foreach ($url->attributes as $a) { echo "<br>$a->name is $a->value"; } echo "<hr><br>"; } When I do this, I only see 'href' as an attribute of the url, there's no way to get the 'anchor text' (in the above case 'Test'). How can I get the anchor text of the link?

• Specific Strings And NSScanner

  - by Garry

  I need to determine whether a string (sourceString) contains another string (queryString) and if it does, at what offset. I'm guessing that NSScanner might do the trick but I don't fully understand the documentation. Let's say sourceString = @"What's the weather in London today?" If I set queryString to equal @"What's the weather", I'd like a method that would determine that, in this case, YES (sourceString does contain queryString) and the offset is 0 (i.e. at the start of sourceString). Any suggestions?

• Is Classic ADO still viable for a mixed managed/unmanaged App?

  - by Andy Dent

  We have a complex architecture with much logic in unmanaged code that needs database access. Currently this is via ODBC drivers and MFC classes and we're considering the issues of migrating our abstraction layer to use ADO or ADO.Net. In the latter case we'd have to be pushing database logic back up into the .Net layer. I'm trying to decide if the pain of invoking the database via .Net callbacks is offset by the improvements in ADO.Net. The Wikipedia comparison was interesting although I'm not sure I believe all the points in the comparison table (eg: does ADO.Net always use XML to pass data?). A 2005 comparison shows ADO.Net performing dramatically faster. Microsoft's guide to ADO.Net for ADO programmers suggests we will gain much from going to ADO.Net especially the way that data is available in native (.Net) types rather than solely through OLEAutomation's Variant.
