  • Resources for TDD aimed at Python Web Development

    - by Null Route
    I am a hacker not and not a full-time programmer but am looking to start my own full application development experiment. I apologize if I am missing something easy here. I am looking for recommendations for books, articles, sites, etc for learning more about test driven development specifically compatible with or aimed at Python web application programming. I understand that Python has built-in tools to assist. What would be the best way to learn about these outside of RTFM? I have searched on StackOverflow and found the Kent Beck's and David Astels book on the subject. I have also bookmarked the Wikipedia article as it has many of these types of resources. Are there any particular ones you would recommend for this language/application?

  • Condition check inside a function or before its call?

    - by Ashwin
    Which of these 2 programming styles do you prefer? Why? Are there particular advantages to one over the other? // Style 1 if (doBorder) doTheBorder(); if (doFrame) doTheFrame(); if (doDraw) doTheDraw(); void doTheBorder() { // ... } void doTheFrame() { // ... } void doTheDraw() { // ... } // Style 2 doTheBorder(); doTheFrame(); doTheDraw(); void doTheBorder() { if (!doBorder) return; // ... } void doTheFrame() { if (!doFrame) return; // ... } void doTheDraw() { if (!doDraw) return; // ... }

  • Redirect Log output to sdcard on customer's phone

    - by Tom
    My customers are having a problem with my app, and I have been unable to reproduce the problem on my development phone. How to debug this problem? The android Log class is great, but my customers do not know how to use 'adb' or the USB debug cable. Is there some way to redirect Log output to a file on the phone's SD card? Then the customer could easily email the log file to me. Even if this redirection requires programming on my part, I could at least distribute a 'debug' version of the app. Thanks, Tom

  • How can I tell if a given hWnd is still valid?

    - by Ian P
    Please forgive my ignorance, I'm completely new when it comes to winforms programming. I'm using a third-party class that spawns an instance of Internet Explorer. This class has a property, hWnd, that returns the hWnd of the process. Later on down the line, I may want to reuse the instance of the application if it still exists, so I need to tell my helper class to attach to it. Prior to doing that, I'd like to know if the given hWnd is still valid, otherwise I'll spawn another instance. How can I do this in C# & .NET 3.5? Thanks for the help and I apologize if my winforms nomenclature is all wacky.. haha Ian

  • Is ORM (Linq, Hibernate...) really that useful?

    - by Peter
    I have been playing with some LINQ ORM (LINQ directly to SQL) and I have to admit I like its expressive powers . For small utility-like apps, It also works quite fast: dropping a SQL server on some surface and you're set to linq away. For larger apps however, the DAL never was that big of an issue to me to setup, nor maintain, and more often than not, once it was set, all the programming was not happening there anyway... My, honest - I am an ORM newbie - question : what is the big advantage of ORM over writing a decent DAL by hand? (seems like a double, couldn't find it though) UPDATE : OK its a double :-) I found it myself eventually : ORM vs Handcoded Data Access Layer

  • Redirect print in Python: val = print(arg) to output mixed iterable to file

    - by emcee
    So lets say I have an incredibly nested iterable of lists/dictionaries. I would like to print them to a file as easily as possible. Why can't I just redirect print to a file? val = print(arg) gets a SyntaxError. Is there a way to access stdinput? And why does print take forever with massive strings? Bad programming on my side for outputting massive strings, but quick debugging--and isn't that leveraging the strength of an interactive prompt? There's probably also an easier way than my gripe. Has the hive-mind an answer?

  • How stable or unstable is symfony 2.0 ?

    - by Doron
    Well, I know it's a preview, and I know it says that it's not yet ready for production, and yet I dare ask the question. I need to start building a pretty big application, which is planned to go live at around sep-oct 2010. Lets say I will not release the application to production until the stable version of symfony 2.0 will be released - is it a good idea (well, I'll settle for a viable idea) for me to start building the application using the 2.0 version ? How big is the chance I will need to rewrite/replace code I've written due to core changes in the framework ? Thanks. Edit: the other option right now, is to use symfony 1.4. I have thought and tried Zend Framework, but I refuse to re-invent each and every module, which will cost me a lot of programming hours (if not days/weeks).

    - by Sarah
    Hello, I know that it may sound a silly question but i am really very confused. I am to work with one application that is having operations like PDF loading,annotation, scrolling,zooming and other such functions. Now my question is that i am little bit confused about what template i should use as i went through Quartz 2D Programming Guide and was little bit confused whether i'll be able to apply the above shown functions with the same guideline,as it displays the pdf page on the whole screen. Or is there any other way around? Please help me..Can i use UIWebView for the same functions as i listed above? I ll be grateful if you can help me. Thank you.

  • amazon ec2 ubuntu with gitlab and nginx - cant load?

    - by thebluefox
    Ok, so I've spooled up an Amazon EC2 server running Ubuntu, and then followed the instructions below to install GitLab; http://doc.gitlab.com/ce/install/installation.html The only step I've not been able to complete is running the following check on the status; sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production I get the following error; rake aborted! Errno::ENOMEM: Cannot allocate memory - whoami Which I presume is becuase my EC2 is just running a free tier setup, so isn't that well spec'd. Regardless, I've been trying to access this through my browser. I've set up the elastic IP and pointed my domain at it (for the purpose of this, lets say its git.mydom.co.uk). Doing a whois on this domain shows me its pointing to the right place. For some reason though, I get the "Oops, Chrome could not connect to git.mydom.co.uk". Now - for a period of time I was getting the Nginx holding page (telling me I still needed to perform configuration). This though disappeared after removing the default file from /etc/nginx/sites-enabled/ (after reading this could be issue on a troubleshooting page). Since then, I've had nothing, even when I symlinked the file back in from /sites-available. I've tried changing the owner of the git.mydom.co.uk file sat inside /sites-enabled and /sites-available to www-data, as suggested here, but I could only change the permission of the file in /sites-available, and not the symlinked one in /sites-enabled. The content of this file is as follows; upstream gitlab { server unix:/home/git/gitlab/tmp/sockets/gitlab.socket; } server { listen *:80 default_server; # e.g., listen 192.168.1.1:80; In most cases *:80 is a good idea server_name git.mydom.co.uk; # e.g., server_name source.example.com; server_tokens off; # don't show the version number, a security best practice root /home/git/gitlab/public; # Increase this if you want to upload large attachments # Or if you want to accept large git objects over http client_max_body_size 20m; # individual nginx logs for this gitlab vhost access_log /var/log/nginx/gitlab_access.log; error_log /var/log/nginx/gitlab_error.log; location / { # serve static files from defined root folder;. # @gitlab is a named location for the upstream fallback, see below try_files $uri $uri/index.html $uri.html @gitlab; } All the paths mentioned in here look ok...I'm about at the end of my knowledge now!

  • C++ option/long option implementation

    - by K Hein
    I am working on a parser for meta programming language using C++ on Linux platform. Right now, I need to implement option/long option for the parser to provide some additional features. Basically, if the user pass in some additional option, the parser needs to store statistics while parsing the text files. I can think of two ways to implement it. One way is to user global to store options entered by users. Another way is to create a singleton class to store options. So I would like to know if there is any other way to implement it. What is the best/most recommended way of implementing it? Thanks in advance. Regards, K.Hein

  • display classes of a namespace in visual studio (C#)

    - by ericyoung7001
    I am a Java programmer, and just starting to use Visual Studio to do C# programming. In Java IDE such as Eclipse, if I do not know the classname in a package, I can just type a dot (.) after a package name, then I will get a list of all the classes in that package in the IDE. How I can configure visual studio to do the similar thing, say, if I click a namespace name in a file (for example, using System), or add a dot after the namespace, all the classes in that namespace will be displayed somewhere in the IDE?

  • Android: Saving custom button and spinner

    - by Jacob Huggart
    Hello All, I am new to Android programming and was handed a fairly large program that is almost complete, but needed support for switching between portrait and landscape view. I added android:configChanges="keyboardHidden|orientation" to the manifest and used onConfigurationChanged to save the view data and that works. However, there is a button that displays the date selected (when pressed a calendar to select the date comes up) and a spinner that displays the current view and is used to select a new view. Those two items are being cleared/reset and do not work at all after the screen flip. I have been attempting to use onSaveInstanceState and onRestoreInstanceState to fix that, but I cannot figure out how to get it to work. Any advice?

  • nginx + Jetty - thousands of connections stuck in LAST_ACK

    - by virulence
    I have a FreeBSD machine with jails -- two in particular, one that runs nginx and another that runs a Java program that accepts requests via Jetty (embedded mode) Jetty receives upwards of 500 requests/sec constantly and there has been an issue lately where I will constantly have over 60,000 connections in the LAST_ACK state between nginx and jetty. Distribution of all connections (includes some other services, particularly php-fpm) root@host:/root # netstat -an > conns.txt root@host:/root # cat conns.txt | awk '{print $6}' | sort | uniq -c | sort -n 18 LISTEN 112 CLOSING 485 ESTABLISHED 650 FIN_WAIT_2 1425 FIN_WAIT_1 3301 TIME_WAIT 64215 LAST_ACK Distribution of nginx - jetty connections root@host:/root # cat conns.txt | grep '10.10.1.57' | awk '{print $6}' | sort | uniq -c | sort -n 1 3 CLOSE_WAIT 3 LISTEN 18 FIN_WAIT_2 125 ESTABLISHED 64193 LAST_ACK I'd prefer every request to fully close the connection. Clients requests are about 10 minutes apart from each other so connections must be closed. Some of the connections, tcp4 0 0 10.10.1.50.46809 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46805 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46797 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46794 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46790 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46789 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46771 10.10.1.57.9050 LAST_ACK etc.. On Jetty's end I've set maxIdleTime to 2000 -- before this all connections were in ESTABLISHED but they are now LAST_ACK On Jetty's end I've set Connection: close (i.e response.setHeader(HttpHeaders.CONNECTION, HttpHeaderValues.CLOSE);) Jetty never reports a lot of open connections -- always very few. PF/IPFW is not currently being used nginx - reset_timedout_connection is on I cannot figure out how to get nginx or jetty to forcibly close the connection, is this simply something that needs to be fixed in Jetty so that it fully closes the socket after the request finishes? Thanks a lot in advance EDIT: forgot my nginx config for the proxy setup- proxy_pass http://10.10.1.57:9050; proxy_set_header HTTP_X_GEOIP $http_x_geoip; proxy_set_header GEOIP_COUNTRY_CODE $geoip_country_code; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_set_header Connection ""; proxy_http_version 1.1; EDIT2: Forcing Jetty to close the connection via request.getConnection().getEndPoint().close() does nothing -- it's obvious the connection IS being closed (as it's in LAST_ACK) but why isn't it getting past this? Is Nginx keeping the connection open to the backend for some reason?

  • Apache modules: C module vs mod_wsgi python module - Performance

    - by Gopal
    Hi A client of ours is asking us to implement a module in C in Apache webserver for performance reasons. This module should handle RESTful uri's, access a database and return results in json format. Many people here have recommended python mod_wsgi instead - but for simplicity of programming reasons. Can anyone tell me if there is a significant difference in performance between the mod_wsgi python solution vs. the Apache + C.module. Any anecdotes? Pointers to some study posted online?

  • What is a good Very-High level UI framework for JavaScript?

    - by Robert Gould
    I need to write a temporary Web-based graphical front-end for a custom server system. In this case performance and scalability aren't issues, since at most 10 people may check the system simultaneously. Also it should be PHP or Python (server) & JavaScript (client) (can't use Flex or Silverlight for very specific non-programming related issues). So I know I could use YUI or jQuery, but was wondering if there is something even more high-level that would say allow me to write such a little project within a few hours of work, and get done with it. Basically I want to be as lazy as possible (this is throw-away code anyways) and get the job done in as little time as possible. Any suggestions?

  • How to query data from a password protected https website using C# .NET

    - by Addie
    I'd like my application to query a csv file from a secure website. I have no experience with web programming so I'd appreciate detailed instructions. Currently I have the user login to the site, manually query the csv, and have my application load the file locally. I'd like to automate this by having the user enter his login information, authenticating him on the website, and querying the data. The application is written in C# .NET. The url of the site is: https://www2.emidas.com/default.asp. I've tested the following code already and am able to access the file once the user has already authenticated himself and created a manual query. System.Net.WebClient Client = new WebClient(); Stream strm = Client.OpenRead("https://www3.emidas.com/users/<username>/file.csv");

  • In what language was MSDOS originally written?

    - by nebukadnezzar
    In what language was MSDOS originally written in? The Wikipedia Article implies either C, QBasic or Pascal, but: C was invented to write UNIX, so I don't believe it was used to write MSDOS Pascal seems popular to teach programming, but not really popular to write Operating systems in QBasic didn't seem to be very popular for Operating Systems at the time MSDOS was developed (or was *BASIC ever very popular to write Operating Systems in it?) Except these three languages there is also Assembly, but I assume that Microsoft already switched from Assembly to a "higher" level language? Since C was originally invented for UNIX, I still wouldn't think Microsoft is using C... although the Microsoft API is written in C (I find this kind-of oxymoronic, actually). Can anyone enlighten me on this topic?

  • PHP - Frameworks, ORM, Encapsulation.

    - by Ian
    Programming languages/environments aside, are there many developers who are using a framework in PHP, ORM and still abide by encapsulation for the DAL/BLL? I'm managing a team of a few developers and am finding that most of the frameworks require me to do daily code inspection because my developers are using the built in ORM. Right now, I've been using a tool to generate the classes and CRUD myself, with an area for them to write additional queries/functions. What's been happening though, is they are creating vulnerabilities by not doing proper checks on data permission, or allowing the key fields to be manipulated in the form. Any suggestions, other than get a new team and a new language (I've seen Python/Ruby frameworks have the same issues).

  • Netlink user-space and kernel-space communication

    - by sasayins
    Hi, I am learning programming in embedded systems using Linux as my main platform. And I want to create a Device Event Management Service. This service is a user-space application/daemon that will detect if a connected hardware module triggered an event. But my problem is I don't know where should I start. I read about Netlink implementation for userspace-kernelspace communication and it seems its a good idea but not sure if it is the best solution. But I read that the UDEV device manager uses Netlink to wait a "uevent" from the kernel space but it is not clear for me how to do that. I read about polling sysfs but it seems it is not a good idea to poll filesystem. What do you think the implementation that should I use in my service? Should I use netlink(hard/no clue how to) or just polling the sysfs(not sure if it works)? Thanks

  • Best approach to design a service oriented system

    - by Gustavo Paulillo
    Thinking about service orientation, our team are involved on new application designs. We consist in a group of 4 developers and a manager (that knows something about programming and distributed systems). Each one, having own opinion on service design. It consists in a distributed system: a user interface (web app) accessing the services in a dedicated server (inside the firewall), to obtain the business logic operations. So we got 2 main approachs that I list above : Modular services Having many modules, each one consisting of a service (WCF). Example: namespaces SystemX.DebtService, SystemX.CreditService, SystemX.SimulatorService Unique service All the business logic is centralized in a unique service. Example: SystemX.OperationService. The web app calls the same service for all operations. In your opinion, whats the best? Or having another approach is better for this scenario?

  • SQL Server Agent 2005 job runs but no output

    - by alimack
    Essentially I have a job which runs in BIDS and as as a stand lone package and while it runs under the SQL Server Agent it doesn't complete properly (no error messages though). The job steps are: 1) Delete all rows from table; 2) Use For each loop to fill up table from Excel spreasheets; 3) Clean up table. I've tried this [MS page][1] (steps 1 & 2), didn't see any need to start changing from Server side security. Also SQLServerCentral.com for [this page][2], no resolution. How can I get error logging or a fix? Note I've reposted this from Server Fault as it's one of those questions that's not pure admin or programming. I have logged in as the proxy account I'm running this under, and the job runs stand alone but complains that the Excel tables are empty?

  • Disabling mouse movement and clicks altogether in c#

    - by ThaNerd
    At work, i'm a trainer. I'm setting up lessons to teach people how to "do stuff" without a mouse... Ever seen people click "login" textbox, type, take the mouse, click "password", type their password, then take the mouse again to click the "connect" button beneath ? So i'll teach them how to do all that without a mouse (among many other things, of course) At the end of the course, i'll make them pass a sort of exam. So i'm building a little wizard based app in which i present some simili-real-life examples of forms to fill in, but i want to disable their mouse programatically while they do this test. However, further in the wizard, i'll have to let them use their mouse again. Is there a -- possibly easy -- way to just disable the mouse for a while, and re-enable it later on? I'm on C# 2.0, programming under VC# 2k5, if that matters

But it 404's on the SQL Compact 4.0 CPT2 and it's tools. I was able to get the runtime from the Microsoft downloads page but the tools I am not able to find. I can not install WebMatrix because the tools are a prerequisite. Does anybody know where to get them from now?
