• What's a good Minimal Server-Side Javascript Framework?

  - by Nick Retallack

  So I was writing a web app with web.py that uses plenty of client-side javascript, and my database is on couchdb so the queries are in javascript too, and eventually I just got to thinking, why not skip the python and go all javascript? Besides, some functions need to run once on the client and again on the server to make sure you're not spoofing, so why translate between javascript and python? So I'm looking for a simple lightweight javascript web framework. All I really need is the url routing, request and response stuff (standard wsgi?), and a way to hook into a big http server like nginx. What do you guys recommend?

• SVN project folder tree structure vs production folder tree structure

  - by Marco Demaio

  While developing a PHP+JS web application we always try to separate big blocks of code into small modules/components, in order to make these last ones as much reusable as possible in other applications. Let's say we now have: the EcommerceApp (an ecommerce main application) a Server-file-mgr component (a component to view/manage file on server) a Mylib (a library of useful functions) a MailistApp (another main application to handle mail lists) ... EcommerceApp needs both Server-file-mgr component and Mylib to work Server-file-mgr needs Mylib to work MaillistApp needs both Server-file-mgr component and Mylib to work too. My idea is to simply structure the SVN project folder tree putting everything at the same level: trunk/EcommerceApp trunk/Server-file-mgr trunk/Mylib trunk/MaillistApp But in real life to make these apps to work the folder tree structure must be the following: EcommerceApp |_ Mylib |_ Server-file-mgr MaillistApp |_ Mylib |_ Server-file-mgr I mean Mylib and Server-file-mgr needs to be inside the EcommerceApp/MaillistApp folder. How would you then structure the SVN folder, as I did or in a different/better/smarter way???

• Testing sample code in python modules

  - by Andrew Walker

  I'm in the process of writing a python module that includes some samples. These samples aren't unit-tests, and they are too long and complex to be doctests. I'm interested in best practices for automatically checking that these samples run. My current project layout is pretty standard, except that there is an extra top level makefile that has build, install, unittest, coverage and profile targets, that delegate responsibility to setup.py and nose as required. projectname/ Makefile README setup.py samples/ foo-sample foobar-sample projectname/ __init__.py foo.py bar.py tests/ test-foo.py test-bar.py I've considered adding a sampletest module, or adding nose.tools.istest decorators to the entry-point functions of the samples, but for a small number of samples, these solutions sound a bit ugly. This question is similar to http://stackoverflow.com/questions/301365/automatically-unit-test-example-code, but I assume python best practices will differ from C#

• XML documentation to context sensitive help

  - by Yonas

  These days a number of commercial and open source tools have been developed for this purpose. However(unfortunately), non of them meet my requirement for specific problem I am dealing with. Currently, I am working on a project that exposes a different classes and functions to user as scripting interface. the user can use the objects from custom scripting interface and call methods to solve some specific problem. The problem I am facing is users of my classes need some sort of documentation in order to write their script efficiently. To address this problem am planing to use the compiler generated XML file to provide context sensitive help, which allows users to mouse over on any of the controls and corresponding methods from the GUI and read the reference documentation of the class/method. Now ... here are my questions: Can I get the sample source code? Can any one give me someone point me to some sort of best approach to address the problem?

• Java Prepared Statement arguments!

  - by Epitaph

  I am planning to replace repeatedly executed Statement objects with PreparedStatement objects to improve performance. I am using arguments like the MySQL function now(), and string variables. Most of the PreparedStatement queries I have seen contained constant values (like 10, and strings like "New York") as arguments used for the "?" in the queries. How would I go about using functions like now(), and variables as arguments? Is it necessary to use the "?"s in the queries instead of actual values? I am quite confounded.

• Android app copy protection and data files

  - by Ben Mc

  I'm going to rephrase this question. As it turns out the original answer wasn't definitive and problems were found. ======================================================================= In my app, I access my sqlite database at the following hard-coded location in my code: /data/data/com.mydomain.appname/databases/database.db If I turn ON copy protection in the Market Place, will my app still have access to this location? Or will I have to change it to something like: */data-private/*data/com.mydomain.appname/databases/database.db (or something like this) Since I have a Dev phone only, I have no way of testing to see if my app still functions normally after turning on copy protection. Thank you!

• reinventing the wheels: Node.JS/Event-driven programming v.s. Functional Programming?

  - by ivanTheTerrible

  Now there's all the hype lately about Node.JS, an event driven framework using Javascript callbacks. To my limited understanding, its primary advantage seems to be that you don't have to wait step by step sequentially (for example, you can fetch the SQL results, while calling other functions too). So my question is: how is this different, or better than just functional languages, like CL, Haskell, Clojure etc? If not better, then why don't people just do functional languages then (instead of reinventing the wheel with Javascript)? Please note that I have none experience in either Node.JS nor functional programming. So some basic explanation can be helpful.

• Where do I find a good explanation of Javascript-ese

  - by tzenes

  I realize that title may require explanation. The language I first learned was C, and it shows in all my programs... even those not written in C. For example, when I first learned F# I wrote my F# programs like C programs. It wasn't until someone explained the pipe operator and mapping with anonymous functions that I started to understand the F#-ese, how to write F# like a F# programmer and not a C programmer. Now I've written a little javascript, mostly basic stuff using jquery, but I was hoping there was a good resource where I could learn to write javascript programs like a javascript programmer.

• Creating a multi-page PDF doc

  - by codemercenary

  Hi, has anyone already created a PDF document in an iPad app. i see that there are new functions in the UIKit to do this, but I can't find any code example for this. BOOL UIGraphicsBeginPDFContextToFile ( NSString *path, CGRect bounds, NSDictionary *documentInfo ); void UIGraphicsBeginPDFPage ( void ); I found an example that is supposed to work on the iPhone, but this gives me errors: Fri Apr 30 11:55:32 wks104.hs.local PDF[1963] <Error>: CGFont/Freetype: The function `create_subset' is currently unimplemented.

• what is duck typing?

  - by ashish yadav

  I recently read an article about duck-typing.It said about calling functions of different classes using object of any class. Is it true?And how will the compiler do it on runtime? I apologize if i am not clear.But it really fascinates me , if we could do it dynamically. So if u people got any idea.I am all ears. thank you!! how will the function be accessed by object of any other class. that violates the basic principle of OOP.and that too dynamically during runtime. And is this feature possible in case of OOP languages?

• How to link a SQlite Extension Source File into Xcode for iPhone?

  - by crunchyt

  I use a statically linked library for Sqlite in an iPhone Xcode project. I am now trying to include a .C extension to Sqlite in this project. However, I am having trouble making the Sqlite in the build SEE the extension. The statically linked Sqlite library works fine. Also the .C extension works on my desktop, and builds fine as a statically linked library in Xcode. However, the custom functions it defines are missing when called. For example, I load the extension as so with no errors. SELECT load_extension('extension_name.so'); But when I try to call a function defined in the extension, I get this message DB Error: 1 "no such function: custom_function" Does anyone know much about linking a Sqlite extension into an Xcode project?

• Hex representation of Euro Symbol €

  - by Rahul

  Hi I was using XVI32 (Hex Editor) to get the hex representation of the Euro symbol and it gives me the value as 80. Another site: http://www.string-functions.com/string-hex.aspx does the same. I am not able to understand why the hex representation is 80 instead of 0x20AC. This 0X80 gives 128 in decimal and if I use Alt+0128 it actually produces the Euro symbol. Could somebody throw some light on what could be the logic behind this conversion from string to hex conversion ? Thanks

• jQuery selective hover

  - by Vitor

  Hello everyone, I'm trying to do a simple task with jQuery: I have a list of words which, when hovered, should fadeIn its corresponding image. For example: <a href="#" class="yellow">Yellow</a> <a href="#" class="blue">Blue</a> <a href="#" class="green">Green</a> <img src="yellow.jpg" class="yellow"> <img src="blue.jpg" class="blue"> <img src="green.jpg" class="green"> I'm currently doing it this way for each link/image: $('a.yellow').hover( function () { $('img.yellow').fadeIn('fast'); }, function () { $('img.yellow').fadeOut('fast'); }); The method above works fine, but as I'm still learning, I guess there's a better way to do that instead of repeating functions. Can anyone give me some light here? How can I improve this code?

• how to do this in shell

  - by user150674

  I have a very large file, named 'ColCheckMe', tab-delimited, that you are asked to process. You are told that each line in 'ColCheckMe' has 7 columns, and that the values in the 5th column are integers. Using shell functions indicate how you would verify that these conditions are satisfied in 'ColCheckMe' if In the same file, each value in column 1 is unique. How would I verify that? Also how to write a shell function that counts the number of occurrences of the word “SpecStr” in the file 'ColCheckMe' I tried the first part which checks for the valid number of field and checks the 5th field being integer field. nawk ' NF != 7 { printf("[%d] has invalid [%d] number of fields\n", FNR, NF) } $5 !~ /^[0-9]+$/ { printf("[%d] 5th field is invalid [%s]\n", FNR, $5) }' ColCheckMe now i wanna verify in the same file if the value in column 1 is unique. Also is there a way to write a shell function to count the occurrences of the world "SpecStr" in the file 'ColCheckMe' Thanks a lot

• What useful GDB scripts have you used/written?

  - by nik

  People use gdb on and off for debugging, of course there are lots of other debugging tools across the varied OSes, with and without GUI and, maybe other fancy IDE features. I would like to know what useful gdb scripts you have written and liked. While, I do not mean a dump of commands in a something.gdb file that you source to pull out a bunch of data, if that made your day, go ahead and talk about it. Lets think conditional processing, control loops and functions written for more elegant and refined programming to debug and, maybe even for whitebox testing Things get interesting when you start debugging remote systems (say, over a serial/ethernet interface) And, what if the target is a multi-processor (and, multithreaded) system Let me put a simple case as an example... Say, A script that traversed serially over entries to locate a bad entry in a large hash-table that is implemented on an embedded platform. That helped me debug a broken hash-table once.

• Daubechies-4 Transform in MATLAB

  - by Myx

  Hello: I have a 4x4 matrix which I wish to decompose into 4 frequency bands (LL, HL, LH, HH where L=low, H=high) by using a one-level Daubechies-4 wavelet transform. As a result of the transform, each band should contain 2x2 coefficients. How can I do this in MATLAB? I know that MATLAB has dbaux and dbwavf functions. However, I'm not sure how to use them and I also don't have the wavelet toolbox. Any help is greatly appreciated. Thanks.

• Starting to make progress Was [MediaRecorder prepare() causes segfault]

  - by dwilde1

  Folks, I have a situation where my MediaRecorder instance causes a segfault. I'm working with a HTC Hero, Android 1.5+APIs. I've tried all variations, including 3gpp and H.263 and reducing the video resolution to 320x240. What am I missing? The state machine causes 4 MediaPlayer beeps and then turns on the video camera. Here's the pertinent source: UPDATE: ADDING SURFACE CREATE INFO I have rebooted the device based on previous answer to similar question. UPDATE 2: I seem to be following the MediaRecorder state machine perfectly, and if I trap out the MR code, the blank surface displays perfectly and everything else functions perfectly. I can record videos manually and play back via MediaPlayer in my code, so there should be nothing wrong with the underlying code. I've copied sample code on the surface and surfaceHolder code. I've looked at the MR instance in the Debug perspective in Eclipse and see that all (known) variables seem to be instantiated correctly. The setter calls are all now implemented in the exaxct order specced in the state diagram. UPDATE 3: I've tried all permission combinations: CAMERA + RECORD_AUDIO+RECORD_VIDEO, CAMERA only, RECORD_AUDIO+RECORD_VIDEO This is driving me bats! :))) UPDATE 4: starting to work... but with puzzling results. Based on info in bug #5050, I spaced everything out. I have now gotten the recorder to actually save a snippet of video (a whole 2160 bytes!), and I did it by spacing the view visibility, prepare() and start() w.a.a.a.a.a.y out (like several hundred milliseconds for each step). I think what happens is that either bringing the surface VISIBLE has delayed processing or else the start() steps on the prepare() operation before it is complete. What is now happening, however, is that my simple timer tickdown counter is getting clobbered. Is it now that the preview and save operations are causing my main process thread to become unavailable? I'm recording only 10fps at 176x144. Referencing the above code, I've added a timer tickdown after setPreviewDisplay(), prepare() and start(). As I say, it now functions to some degree, but the results still have anomalies. // in activity class definition protected MediaPlayer mPlayer; protected MediaRecorder mRecorder; protected boolean inCapture = false; protected int phaseCapture = 0; protected int durCapturePhase = INF; protected SurfaceView surface; protected SurfaceHolder surfaceHolder; // in onCreate() // panelPreview is an empty LinearLayout surface = new SurfaceView(getApplicationContext()); surfaceHolder = surface.getHolder(); surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); panelPreview.addView(surface); // in timer handler runnable if (mRecorder == null) mRecorder = new MediaRecorder(); mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); mRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); mRecorder.setOutputFile(path + "/" + vlip); mRecorder.setVideoSize(320, 240); mRecorder.setVideoFrameRate(15); mRecorder.setPreviewDisplay(surfaceHolder.getSurface()); panelPreview.setVisibility(LinearLayout.VISIBLE); mRecorder.prepare(); mRecorder.start(); Here is a complete log trace for the process run and crash: I/ActivityManager( 80): Start proc com.ejf.convince.jenplus for activity com.ejf.convince.jenplus/.JenPLUS: pid=17738 uid=10075 gids={1006, 3003} I/jdwp (17738): received file descriptor 10 from ADB W/System.err(17738): Can't dispatch DDM chunk 46454154: no handler defined W/System.err(17738): Can't dispatch DDM chunk 4d505251: no handler defined I/WindowManager( 80): Screen status=true, current orientation=-1, SensorEnabled=false I/WindowManager( 80): needSensorRunningLp, mCurrentAppOrientation =-1 I/WindowManager( 80): Enabling listeners W/ActivityThread(17738): Application com.ejf.convince.jenplus is waiting for the debugger on port 8100...

• Break nested loop in Django views.py with a function

  - by knuckfubuck

  I have a nested loop that I would like to break out of. After searching this site it seems the best practice is to put the nested loop into a function and use return to break out of it. Is it acceptable to have functions inside the views.py file that are not a view? What is the best practice for the location of this function? Here's the example code from inside my views.py @login_required def save_bookmark(request): if request.method == 'POST': form = BookmarkSaveForm(request.POST) if form.is_valid(): bookmark_list = Bookmark.objects.all() for bookmark in bookmark_list: for link in bookmark.link_set.all(): if link.url == form.cleaned_data['url']: # Do something. break else: # Do something else. else: form = BookmarkSaveForm() return render_to_response('save_bookmark_form.html', {'form': form})

• Graphviz DOT arrange Nodes in circles, layout too "compact"

  - by Ivo Wetzel

  I'm halfway there please see the edit OK here's my problem, I'm generating a graph of a python module, including all the files with their functions/methods/classes. I want to arrange it so, that nodes gather in circles around their parent nodes, currently everything is on one gargantuan horizontal row, which makes the thing 50k pixels wide and also let's the svg converter fail(only renders about the half of the graph). I went trough the docs(http://www.graphviz.org/doc/info/attrs.html) but couldn't find anything that seems to do the trick. So the question is: Is there a simple way to do this or do I have to layout the whole thing by myself? :/ EDIT: Thanks to Andrews comment I've got the right layout, the only problem now is that it's a bit to "compact"... so the question now is, how to fix this?

• Python Windows File Copy with Wildcard Support

  - by Wang Dingwei

  I've been doing this all the time: result = subprocess.call(['copy', '123*.xml', 'out_folder\\.', '/y']) if result == 0: do_something() else: do_something_else() Until today I started to look into pywin32 modules, then I saw functions like win32file.CopyFiles(), but then I found it may not support copying files to a directory. Maybe this functionality is hidden somewhere, but I haven't found it yet. I've also tried "glob" and "shutil" combination, but "glob" is incredibly slow if there are many files. So, how do you emulate this Windows command with Python? copy 123*.xml out_folder\. /y

• ruby on rails named scope implementation

  - by Engwan

  From the book Agile Web Development With Rails class Order < ActiveRecord::Base named_scope :last_n_days, lambda { |days| {:conditions => ['updated < ?' , days] } } named_scope :checks, :conditions => {:pay_type => :check} end The statement orders = Orders.checks.last_n_days(7) will result to only one query to the database. How does rails implement this? I'm new to Ruby and I'm wondering if there's a special construct that allows this to happen. To be able to chain methods like that, the functions generated by named_scope must be returning themselves or an object than can be scoped further. But how does Ruby know that it is the last function call and that it should query the database now? I ask this because the statement above actually queries the database and not just returns an SQL statement that results from chaining.

• Knowledge base web app -- need a demo mode

  - by Smandoli

  I was contracted to build an on-line knowledge base that searches and cross-references many thousands of replacement parts for a niche industry. My client furnishes this app to his customers on a subscription basis. It uses MySQL and PHP and it works great. I want to deploy it in "demo mode" to sell my skills. I want the user to see the functions, but I have to guard the data for my client. My first idea was to obfuscate the results. That's at cross-purposes with showing how well it searches. I'm considering a limit on how many searches you can perform, but that's awkward too as someone could visit every day and get more answers than we would prefer. Other posts I've found are about letting people interact with an app, but without the challenge of protecting a big knowledge base. Can you suggest an approach? (Note, I put the tag obfuscation, but not sure it applies because java code obfuscation seems to be unrelated.)

• clear javascript console in Google Chrome

I've tried to console.log(console); and got this functions below... assert: function assert() { [native code] } constructor: function Console() { [native code] } count: function count() { [native code] } debug: function debug() { [native code] } dir: function dir() { [native code] } dirxml: function dirxml() { [native code] } error: function error() { [native code] } group: function group() { [native code] } groupEnd: function groupEnd() { [native code] } info: function info() { [native code] } log: function log() { [native code] } markTimeline: function markTimeline() { [native code] } profile: function profile() { [native code] } profileEnd: function profileEnd() { [native code] } time: function time() { [native code] } timeEnd: function timeEnd() { [native code] } trace: function trace() { [native code] } warn: function warn() { [native code] } __proto__: Object [ I guess there's no way to clear up the console... but I wanted someone to say it to me... ]

• Prototyping Object in Javascript breaks jQuery?

  - by blesh

  I have added a simple .js to my page that has some pretty mundane common-task sort of functions added to the Object and Array prototypes. Through trial and error I've figured out that adding any function to Object.prototype, no matter it's name or what it does causes javascript errors in jQuery: The culprit? Object.prototype.foo = function() { /*do nothing and break jQuery*/ }; The error I'm getting line 1056 of jquery-1.3.2.js, in the attr:function { } declaration: /*Object doesn't support this property or method*/ name = name.replace(/-([a-z])/ig, function(all, letter) { return letter.toUpperCase(); }); Apparently G.replace is undefined. While it's obvious that there's something I'm just not wrapping my head around with prototyping, I'm failing miserably to figure out what it is. To be clear, I'm not looking for a workaround, I have that handled... what I'm looking for is an answer to 'Why?'. Why does adding a function to Object.prototype break this bit of code?

• NSNumberFormatter crashing iPhone SDK 4.0b2

  - by Ward

  Hey there, I've got an app that's been in the app store for a while and functions perfectly on OS 3.1 - 3.13. However, when tested on 4.0b2 I noticed that it crashes in the same place every time, but only on the device, never on the simulator. I'm using a 3GS to test. On loadView I initialize an NSNumberFormatter object which is declared and retained in the interface so I have access to it everywhere. In my method I call it several times to convert string values into nsnumbers to be stored in a mutable dictionary. Here's an example: [myDictionary setObject:[myStyleFormatter numberFromString:@"1"] forKey:@"hours"]; [myDictionary setObject:[myStyleFormatter numberFromString:@"30"] forKey:@"minutes"]; [myDictionary setObject:[myStyleFormatter numberFromString:@"10"] forKey:@"seconds"]; For some reason it crashes as soon as it tries to set hours. The error is "attempt to insert nil value (key: hours)" Have I been doing something wrong all along? Has the api changed for 4.0b2? Thanks, Howie
