• What are some of the best automated web QA tools out there?

  - by Kant

  Issue We have a series of websites built in ASP.NET that we deploy frequently. Due to the lack of a QA team, we are unable to test the functionality and load of every web page within the site. Question What are some of the top tools for doing QA testing. The tool should include some basic functionality, such as: Notifying parties when unexpected results occur. Expected results should be configurable (i.e. Hit web page A, if the response doesn't have the string, "My intranet portal" in it, notify the appropriate parties). Any help is appreciated.

• Is there any class in the .NET Framework to represent a holding container for objects?

  - by Charles Prakash Dasari

  I am looking for a class that defines a holding structure for an object. The value for this object could be set at a later time than when this container is created. It is useful to pass such a structure in lambdas or in callback functions etc. Say: class HoldObject<T> { public T Value { get; set; } public bool IsValueSet(); public void WaitUntilHasValue(); } // and then we could use it like so ... HoldObject<byte[]> downloadedBytes = new HoldObject<byte[]>(); DownloadBytes("http://www.stackoverflow.com", sender => downloadedBytes.Value = sender.GetBytes()); It is rather easy to define this structure, but I am trying to see if one is available in FCL. I also want this to be an efficient structure that has all needed features like thread safety, efficient waiting etc. Any help is greatly appreciated.

• Why is it a bad idea to use ClientLogin for web apps in the Google API?

  - by Onema

  I just picked up the Google API today to allow some users of our site to upload videos to our own organization YouTube account. I Don't want our users to know our user name and password, but rather give them the option if they want to upload videos to youtube or not. If they choose to do it, they check on a check box and hit the submit button. I keep seeing over, and over in the Developers guide that ClientLogin, which to me looks like the best option to implement what I want to do, is not a good idea for user authentication in web applicaitons. The "AuthSub for web applications" doesn't seem to be the best mechanism for what I want to implement! Any ideas on what to do? Thank you

• How can I tell if my live web-server is overloaded?

  - by Nick G

  We have a live webserver which doesn't seem to be performing all that well. It's a Dell PowerEdge machine, a few years old (dual core, 4GB) which is hosting about 20 low-traffic websites. However it doesn't seem to be as fast as it used to be. How can we determine the cause of this? If it's website traffic, I would be expecting high CPU but CPU usage is quite low and hovers around the 15-30% mark except for very brief periods. I'm wondering perhaps, if rather than CPU performance being a problem, perhaps it's disk thrashing due to the constant read/writes of all the small web files and database queries. It has 4x 7200 RPM SATA drives in RAID 5. So is there a way to check that it's not disk thrashing?

• Will data order in post form be the same to it in web form?

  - by Relax

  Assuming there are 5 inputs in web form <input name='the_same' value='different' /> <input name='the_same' value='different' /> <input name='the_same' value='different' /> <input name='the_same' value='different' /> <input name='the_same' value='different' /> When server side receive the post data, i use a foreach to accept data, say $the_same = new array(); foreach($_REQUEST as $data) $the_same[] = $data; Will the order of data saved in server side be the same to it in web form?

• what's the correct way to crop art when saving for web in Adobe Illustrator?

  - by jela

  I need to save a bunch of illustrations for web use, and I cannot find any 'crop to art dimensions' option when saving them. I've therefore been creating a new artboard for each illustration by clicking on the art with the artboard tool, then deleting the old artboard. This works OK except the new artboard ignores the stroke, so I then have to go back and tweak all the edges of the artboard before saving, or else the stroke edges get cut off. This gets old after hundreds of illustrations. Is there an easier way to do it?

• How to make the Microsoft Word 2010 web install version completely download itself?

  - by Paperflyer

  I installed Microsoft Word 2010 using the handy web installation feature. The way this works is that Word installs a bare minimum of functionality and any time it needs a feature that has not been downloaded yet, it will download it in-place just as needed. The thing is, this is stalling Word every few minutes. Every few minutes, Word takes a small nap while it tries to find some obscure feature somewhere. This is really annoying. Is there a way to just tell the thing to completely download itself? This was a nice functionality for the trial but it is extremely annoying in actual use.

• How to suppress the inclusion of the .Net framework in a installation package created with visual st

  - by Dabblernl

  I built a very simple installation package that only consists of some merge modules. The Setup project explorer shows no dependencies on .Net for these merge modules (and it should not). However, on building the .msi file a requierement for .Net is added to it. Can this be avoided, or do I have to use a third party .msi builder? (I tried the obvious unchecking of any checkbox in the requierements listbox.)

• How can I determine Breaking point of my Web application using JMeter?

  - by Gopu Alakrishna

  How can I determine Breaking point of my Web application using JMeter? I have executed the JMeter Testplan with different concurrent users load. EX. 300 users(0% error), 400 users(7% error in a sample, 5% error in another sample), 500 users(more than 10% error in 4 out of 6 samples). At What value of % Error, I can say system reached the Breaking point.I used concurrent users 300, 400, 500 in a PHP website. Should I consider any other parameter to determine breaking point. How many maximum concurrent users my application can support?

• Apache web server: "proxying" a webapp from another server?

  - by Riddler

  Sorry for the lame terminology - I'm no way a sysadmin... So here's the deal. I have two Linux boxes in the same network, let's refer to those boxes by their IPs, a.b.c.d and e.f.g.h. Each box runs some webapp, normally available like http://a.b.c.d/ and http://e.f.g.h/. What I want to accomplish is this: with some Apache web server (which by the way lives on both boxes) configuration voodoo, the first app would be available via http://a.b.c.d/whatever1/, and the 2nd app would be available as http://a.b.c.d/whatever2/ - but would still reside on another server (e.f.g.h). Long story short - is it at all possible to do this with Apache configuration magic and without touching the webapps and their configuration? If so - how? :) Thanks in advance!

• iOS Question. Is There a Framework for Build Time Based Apps.

  - by dugla

  I have the need for some time based effects in the iPad app I am building. The UIView class animation capability beginAnimatins/commitAnimations is exactly the sort of thing I am looking for but it is restricted to specific properties of UIView deemed animatable. Ideally, I am looking for a solution that lets me drive an a time-based function that can perhaps send messages to a class of my own choosing at the rate I specify in the animation. Specifically, I have a function - my implementation of the RenderMan function "smoothstep" which is essentially an ease-in ease-out curve common in animation. It takes [0 - 1] as input and outputs [0 - 1] as the curve is evaluated. I want to drive this function for a duration of my own choosing at rate of my own choosing. Thanks in advance. -Doug

• What block is not being tested in my test method? (VS08 Test Framework)

  - by daft

  I have the following code: private void SetControlNumbers() { string controlString = ""; int numberLength = PersonNummer.Length; switch (numberLength) { case (10) : controlString = PersonNummer.Substring(6, 4); break; case (11) : controlString = PersonNummer.Substring(7, 4); break; case (12) : controlString = PersonNummer.Substring(8, 4); break; case (13) : controlString = PersonNummer.Substring(9, 4); break; } ControlNumbers = Convert.ToInt32(controlString); } Which is tested using the following test methods: [TestMethod()] public void SetControlNumbers_Length10() { string pNummer = "9999999999"; Personnummer target = new Personnummer(pNummer); Assert.AreEqual(9999, target.ControlNumbers); } [TestMethod()] public void SetControlNumbers_Length11() { string pNummer = "999999-9999"; Personnummer target = new Personnummer(pNummer); Assert.AreEqual(9999, target.ControlNumbers); } [TestMethod()] public void SetControlNumbers_Length12() { string pNummer = "199999999999"; Personnummer target = new Personnummer(pNummer); Assert.AreEqual(9999, target.ControlNumbers); } [TestMethod()] public void SetControlNumbers_Length13() { string pNummer = "1999999-9999"; Personnummer target = new Personnummer(pNummer); Assert.AreEqual(9999, target.ControlNumbers); } For some reason Visual Studio says that I have 1 block that is not tested despite showing all code in the method under test in blue (ie. the code is covered in my unit tests). Is this because of the fact that I don't have a default value defined in the switch? When the SetControlNumbers() method is called, the string on which it operates have already been validated and checked to see that it conforms to the specification and that the various Substring calls in the switch will generate a string containing 4 chars. I'm just curious as to why it says there is 1 untested block. I'm no unit test guru at all, so I'd love some feedback on this. Also, how can I improve on the conversion after the switch to make it safer other than adding a try-catch block and check for FormatExceptions and OverflowExceptions?

• Decorators vs. classes in python web development.

  - by Tristan

  I've noticed three main ways Python web frameworks deal request handing: decorators, controller classes with methods for individual requests, and request classes with methods for GET/POST. I'm curious about the virtues of these three approaches. Are there major advantages or disadvantages to any of these approaches? To fix ideas, here are three examples. Bottle uses decorators: @route('/') def index(): return 'Hello World!' Pylons uses controller classes: class HelloController(BaseController): def index(self): return 'Hello World' Tornado uses request handler classes with methods for types: class MainHandler(tornado.web.RequestHandler): def get(self): self.write("Hello, world") Which style is the best practice?

• Which are the best techniques to protect a 'homemade' framework from unlogged visitors?

  - by Hermet

  First of all, I would like to say that I have used the search box looking for a similar question unsuccessfully, maybe because of my poor english skills. The way I currently do this is checking in every single page that a session has been opened. If not, the user gets redirected to a 404 page, to seem like the file which has been requested doesn't exist. I really don't know if this is sure or there's a better and more safety way and I'm currently working with kind of confidential data that should never become public. Could you give me some tips? Or leave a link where I could find some? Thank you very much, and again excuse me for kicking the dictionary.

• How to setup Lucene/Solr for a B2B web app?

  - by Bill Paetzke

  Given: 1 database per client (business customer) 5000 clients Clients have between 2 to 2000 users (avg is ~100 users/client) 100k to 10 million records per database Users need to search those records often (it's the best way to navigate their data) Possibly relevant info: Several new clients each week (any time during business hours) Multiple web servers and database servers (users can login via any web server) Let's stay agnostic of language or sql brand, since Lucene (and Solr) have a breadth of support For Example: Joel Spolsky said in Podcast #11 that his hosted web app product, FogBugz On-Demand, uses Lucene. He has thousands of on-demand clients. And each client gets their own database. They use an index per client and store it in the client's database. I'm not sure on the details. And I'm not sure if this is a serious mod to Lucene. The Question: How would you setup Lucene search so that each client can only search within its database? How would you setup the index(es)? Where do you store the index(es)? Would you need to add a filter to all search queries? If a client cancelled, how would you delete their (part of the) index? (this may be trivial--not sure yet) Possible Solutions: Make an index for each client (database) Pro: Search is faster (than one-index-for-all method). Indices are relative to the size of the client's data. Con: I'm not sure what this entails, nor do I know if this is beyond Lucene's scope. Have a single, gigantic index with a database_name field. Always include database_name as a filter. Pro: Not sure. Maybe good for tech support or billing dept to search all databases for info. Con: Search is slower (than index-per-client method). Flawed security if query filter removed. One last thing: I would also accept an answer that uses Solr (the extension of Lucene). Perhaps it's better suited for this problem. Not sure.

• Is it possible to use Django's testing framework without having CREATE DATABASE rights?

  - by superjoe30

  Since I don't have a hundred bazillion dollars, my Django app lives on a shared host, where all kinds of crazy rules are in effect. Fortunately, they gave me shell access, which has allowed me to kick butts and take names. However I can't do anything about not having CREATE DATABASE rights. I'm using postgresql and have a killer test suite, but am unable to run it due to the code not being able to create a new database. However I am able to create said database beforehand via cPanel and use it with Django. I just don't have CREATE DATABASE rights. Is there a way I can still run my test suite?

• How do Go web apps function from a server perspective?

  - by Metropolis

  Hey Everyone, I followed the directions on how to create web applications using Go, and I was able to get an application working great. One thing I am confused about though is, when you run the application (./8.out), the terminal will sit there and listen on port 8080 until somebody accesses a page. Does the terminal need to stay up all of the time to run the web application? Does the application act like apache? Does apache need to be run next to this app? Setting this up on a server environment seems very confusing to me right now because I dont understand what the best way to do this is. Thanks for any help on this, Metropolis

• Objective-C memory management issue

  - by Toby Wilson

  I've created a graphing application that calls a web service. The user can zoom & move around the graph, and the program occasionally makes a decision to call the web service for more data accordingly. This is achieved by the following process: The graph has a render loop which constantly renders the graph, and some decision logic which adds web service call information to a stack. A seperate thread takes the most recent web service call information from the stack, and uses it to make the web service call. The other objects on the stack get binned. The idea of this is to reduce the number of web service calls to only those appropriate, and only one at a time. Right, with the long story out of the way (for which I apologise), here is my memory management problem: The graph has persistant (and suitably locked) NSDate* objects for the currently displayed start & end times of the graph. These are passed into the initialisers for my web service request objects. The web service call objects then retain the dates. After the web service calls have been made (or binned if they were out of date), they release the NSDate*. The graph itself releases and reallocates new NSDates* on the 'touches ended' event. If there is only one web service call object on the stack when removeAllObjects is called, EXC_BAD_ACCESS occurs in the web service call object's deallocation method when it attempts to release the date objects (even though they appear to exist and are in scope in the debugger). If, however, I comment out the release messages from the destructor, no memory leak occurs for one object on the stack being released, but memory leaks occur if there are more than one object on the stack. I have absolutely no idea what is going wrong. It doesn't make a difference what storage symantics I use for the web service call objects dates as they are assigned in the initialiser and then only read (so for correctness' sake are set to readonly). It also doesn't seem to make a difference if I retain or copy the dates in the initialiser (though anything else obviously falls out of scope or is unwantedly released elsewhere and causes a crash). I'm sorry this explanation is long winded, I hope it's sufficiently clear but I'm not gambling on that either I'm afraid. Major big thanks to anyone that can help, even suggest anything I may have missed?

• Why is my concurrency capacity so low for my web app on a LAMP EC2 instance?

  - by AMF

  I come from a web developer background and have been humming along building my PHP app, using the CakePHP framework. The problem arose when I began the ab (Apache Bench) testing on the Amazon EC2 instance in which the app resides. I'm getting pretty horrendous average page load times, even though I'm running a c1.medium instance (2 cores, 2GB RAM), and I think I'm doing everything right. I would run: ab -n 200 -c 20 http://localhost/heavy-but-view-cached-page.php Here are the results: Concurrency Level: 20 Time taken for tests: 48.197 seconds Complete requests: 200 Failed requests: 0 Write errors: 0 Total transferred: 392111200 bytes HTML transferred: 392047600 bytes Requests per second: 4.15 [#/sec] (mean) Time per request: 4819.723 [ms] (mean) Time per request: 240.986 [ms] (mean, across all concurrent requests) Transfer rate: 7944.88 [Kbytes/sec] received While the ab test is running, I run VMStat, which shows that Swap stays at 0, CPU is constantly at 80-100% (although I'm not sure I can trust this on a VM), RAM utilization ramps up to about 1.6G (leaving 400M free). Load goes up to about 8 and site slows to a crawl. Here's what I think I'm doing right on the code side: In Chrome browser uncached pages typically load in 800-1000ms, and cached pages load in 300-500ms. Not stunning, but not terrible either. Thanks to view caching, there might be at most one DB query per page-load to write session data. So we can rule out a DB bottleneck. I have APC on. I am using Memcached to serve the view cache and other site caches. xhprof code profiler shows that cached pages take up 10MB-40MB in memory and 100ms - 1000ms in wall time. Pages that would be the worst offenders would look something like this in xhprof: Total Incl. Wall Time (microsec): 330,143 microsecs Total Incl. CPU (microsecs): 320,019 microsecs Total Incl. MemUse (bytes): 36,786,192 bytes Total Incl. PeakMemUse (bytes): 46,667,008 bytes Number of Function Calls: 5,195 My Apache config: KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 3 <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 120 MaxRequestsPerChild 1000 </IfModule> Is there something wrong with the server? Some gotcha with the EC2? Or is it my code? Some obvious setting I should look into? Too many DNS lookups? What am I missing? I really want to get to 1,000 concurrency capacity, but at this rate, it ain't gonna happen.

• Why are my DNS Lookups so long (300+ms) when accessing my web site?

  - by Travis

  I'm running a Fedora 11 server with Apache 2. I'm trying to optimize so things are as fast as possible from the server side, and I'm noticing (via Firebug for Firefox) that upon loading the homepage of one of the sites on the web server that for every file it loads (HTML, CSS, JavaScript, GIF, PNG, JPG, etc.), it does a DNS lookup. All of the files it is looking up are local to the server, so I'm surprised to see it even do a DNS lookup. Also, each of these lookups is in the 150-450ms range, which is way too high for my liking. I've tried adjusting /etc/resolve.conf to use Google's Public DNS servers. I restarted the network service and tapped the page again, but the numbers didn't go down. I've reverted back to the default DNS servers since I didn't see any gain. Any ideas on what is causing it to: a) do the dns lookup in the first place, and b) take so long when doing the actual lookup? Thanks in advance.

• Where is a Web Development Career fueled by Passion? [closed]

  - by JMC Creative

  Quick Background Since learning basic html 5 years ago, I've become completely obsessed with the technology, the logic, and the thrill of solving problems involved with building websites. I am still stuck at a thoroughly non-programming type job, but would really like to move into the field of web programming/design. I have no educational background in the field (was trained as a fine artist and tutor), but in the past few years have progressed fully self-taught (and self-motivated) from html to css to php, mysql, jquery, and am now building rich web applications. The Question How can I prove to a company that even though I have no education, I have a passion to learn whatever is thrown my way? ...That essentially I would come at every issue with not only knowledge, but with a passionate desire to solve it, whether that means tackling a new language or debugging code for hours at a time? p.s. Sorry for the stupid title.
