• Running external commands improved a bit

  - by Tomas Mysik

  Hi all, today we would like to show you one small improvement related to running external commands (e.g. generating documentation, running framework commands etc.) which will be available in NetBeans 7.3. First, have a look at the screenshot: As you can see, the first line represents the command that is being executed. In case of any error, this command can be easily copy & pasted to the console for deeper investigation (and proper bug reports ;). Also please notice that the Output window now supports background colors. That's all for today, as always, please test it and report all the issues or enhancements you find in NetBeans Bugzilla (component php, subcomponent Code).

• JMeter: how to asign a single distinct value from CSV Data Set Config to each thread in thread group?

  - by JohnnyM

  I have to make a load test for a relatively large number of users so I cant realy use User Parameters pre-processor to parametrize each thread with custom user data. I've read that I should use CSV Data Set Config instead. However I run into a problem with how JMeter interprets the input of this Config. Example: I have a thread group of 3 threads and Loop Count:10 with one HTTP request sampler with server www.example.com and path: \${user}. The csv file (bullet is a single line in file) for CSV Data Set Config to extract the user parameter: 1 2 3 4 5 Expected output is that for thread 1-x the path of the request should be: \x. So the output file should consist of 10 samples per thread namely: for thread 1-1 : 10 requests to www.example.com\1 for thread 1-2 : 10 requests to www.example.com\2 for thread 1-3 : 10 requests to www.example.com\3 but instead i get requests to each \1 - \5 and then to EOF. Does anyone know how to achieve the expected effect with CSV Data Set Config in jmeter 2.9?

• Looking for parallel programming problem

  - by Chris Lieb

  I am trying to come up with a problem that is easily solvable in a parallel manner and that requires communication between threads for a test. I also am trying to avoid problems that require require random waits, which rules out dining philosophers and producer-consumer (bounded buffer), two of the classics. My goal is for the student to be able to write the program in less than 20-30 minutes in front of a computer not knowing of the problem beforehand. (This is to prevent preparation more than to come up with something novel.) I am trying to stress the communication aspect of the program, though the multi-threaded nature is also important. Does anyone have some ideas? Edit: I'm using Google Go for the language and testing comprehension of the goroutines/channels combo vs an actors library that I authored.

• Un virus biologique utilisé à bon escient pourrait augmenter par dix la capacité des batteries, selon des chercheurs américains

  Un virus biologique utilisé à bon escient pourrait augmenter par dix la capacité des batteries Selon des chercheurs américains Les virus sont connus pour leur capacité de duplication et de destruction. Des chercheurs estiment avoir trouvé le moyen d'exploiter à bon escient leur capacité d'auto-renouvellement. En particulier le virus de la mosaïque du tabac (TMV) qui s'attaquent habituellement aux plantes, en particulier le tabac et les tomates. Ces scientifiques américains, qui travaillent sur la façon d'enrober des petites cellules de virus sur des matériaux conducteurs, ont constaté lors d'un test d'incorporation d'une nanostructure sur une batterie...

• "Testing Plan Lite" for web project

  - by Emmmmm

  How do you draft a quick & easy "Testing Plan Lite" for a medium-sized web project (70k lines, 2 developers)? I've seen many tutorials/articles on methods of testing, but all seem cumbersome. For us, the goal is to be able to be able to divide up and delegate testing instructions to our friends for different project segments, browsers, etc. What's the quick & easy way to write test plans for web apps? (the 20 of the 20/80 rule) Thanks!

• New VHD for testing IE6 and IE7

  - by TATWORTH

  Regrettably old versions of IE (6 and 7)  are still in use and it is necessary to test against them. Microsoft recommended using a Virtual Machine to run these old versions. To this end, Microsoft provide free VHD images at http://www.microsoft.com/downloads/en/details.aspx?FamilyID=21eabb90-958f-4b64-b5f1-73d0a413c8ef&displaylang=en These downloads need to be unpacked and run by Virtual PC which isa free download from http://www.microsoft.com/windows/products/winfamily/virtualpc/default.mspx. If your host PC is Windows 7, use XPMORE from http://xpmore.codeplex.com/ to run the images.

• CMSs & ERPs for hospital management system

  - by Akshey

  Hi, What are the best free CMSs or CMS plugins or ERPs or any other free tools available for developing a hospital management system? I want to develop it for a children's hospital run by my father. The hospital is small with two doctors. Currently, everything is done manually on paper. The main entities who will be using the system are: Receptionist, the two doctors, chemist and the medical laboratorist. They will use it majorly for keeping the records of the patient. The patients would not be interacting with the system directly. The system needs to be user friendly and should be easy to learn. I was thinking to develop such a system using a CMS or an ERP or any other free tool. I have used wordpress/drupal in past but never used an ERP. Can you please guide me to make such a system using free, and preferably open source, tools? Update: I think it will be mostly a form driven system. What would be easy and better: creating the forms in drupal or using a php framework like symphony or cakePHP? Thanks, Akshey

• Unit testing a text index

  - by jplot

  Consider a text index such as a suffix tree or a suffix array supporting Count queries (number of occurrences of a pattern) and Locate queries (the positions of all the occurrences of a pattern) over a given text. How would you go about unit testing such a class ? What I have in mind is to generate a big random string then extract a random substring from this big string and compare the results of both queries with naive implementations (such as string::find). Another idea I have is to find the most frequent substring of length l appearing in the original string (using perhaps a naive method) and use these substrings for testing the index. This isn't the best way, so what would be a good design of the unit tests for a text index ? In case it matters, this is in C++ using google test.

• Improve Bad testing

  - by SetiSeeker

  We have a large team of developers and testers. The ratio is one tester for every one developer. We have full bug tracking and reporting systems in place. We have test plans in place. Every change to the product, the testing team is involved in the design of the feature and are included in the development process as much as possible. We build in small iterative blocks, using scrum methodology and every scrum they are included in, including the grooming sessions etc. But every release of the product, they miss even the most simple and obvious defects. How can we improve this?

• Vista missing from grub bootlist after installing ubuntu

  - by tacomensa

  I installed Ubuntu on a logical partition a while ago. When I get to the grub bootlist, Vista is not there. What i get is this: Ubuntu, with linux 2.6.32-26 Ubuntu, with linux 2.6.32-26 (Recovery mode) Ubuntu, with linux 2.6.32-25 Ubuntu, with linux 2.6.32-26 (Recovery mode) Ubuntu, with linux 2.6.32-24 Ubuntu, with linux 2.6.32-26 (Recovery mode) Memory test (memtest86+) Windows vista (loader) (on/dev/sda1) windows recovery environment (loader) (on/dev/sda2) "Windows vista (loader)" is an acer erecovery manager Im guessing that grub installed on my primary partition so it overwrite the vista MBR and i dont have the option to boot vista. Is there some way i can just edit the MBR and add vista to it or how will i have to repair this? here is my boot script http://pastebin.com/7HZFjBT7

• Chrome Mobile: The Mobile Web Developers Toolkit (Part 1)

  Chrome Mobile: The Mobile Web Developers Toolkit (Part 1) Building for mobile web requires a different mindset than desktop web development, and a different set of tools. The tools we're used to using often aren't available or would take up too much screen real estate. And going back to the dark ages of tweak/save/deploy/test/repeat isn't exactly optimal, so what can we do? Thankfully there are a number of great options - from remote debugging to emulation, mobile browsers are offering more and more tools to make our lives easier. We'll take a look at a couple of tools that you can use today to make cross platform mobile web development easier and then peer into the crystal ball to see what tools may bring in the future. Join us for Part 1 - as we take a look at a few boiler plates, frameworks and helpful libraries for building the mobile web.

• How do I get started with HTML5? [closed]

  - by daniel.sedlacek

  What is the recommended workflow to learn HTML5? What tools should I install? What SDK? Where to start? How to test? How to debug? What do I read? I understand that what is often labelled as "HTML5 development" is in fact a mixture of HTML, CSS, JS and more, however I don't believe that bigger projects are developed in Notepad. That is why I am asking you to reveal your tips and tricks about your workflow.

• How do I get drivers working for an Nvidia GT560i on 12.04?

  - by keepitsimpleengineer

  I been using a test Xubuntu 12.04 LTS on my 64 bit workstation, because Ubuntu has dropped support for the nvidia graphic adapters my 10.04 LTS and I haven't been able to get them working. Now update manager has upgraded the kernel from 3.2.0-30-generic to 3.2.0-31-generic, and failed to produce a working nvidia module that the X server can load. Fortunately, when launching the 3.2.0-30-generic kernel, I still have use of the X server. Does anybody know a work-around or fix for this? I'm really worried, this is the last working Ubuntu distribution OS on the computer and I don't want to give up on Ubuntu. Details of problem here.

• XNA stopped compiling my model x files

  - by HuseyinUslu

  So I've a 3d game project I'm working on and I'm using 2 model files (SkyBlock.x and AimedBlock.x). So until now everything was all good and my models files were compiled all okay and I was able to use them within my game. With the latest changes (which I don't know what caused it really) - XNA stopped compiling my model files and instead only outputs files; AimedBlockxnb - 1kb SkyDome.xnb - 1kb SkyDomeTexture.xnb - 1389 kb SkyDomeTexture_0.xnb - 419 kb So I created a test XNA game project and moved all my asset's to new solution content project's and tried compiling them and saw that they're all good. AimedBlockxnb - 2kb SkyDome.xnb - 13kb SkyDomeTexture.xnb - 4097 kb SkyDomeTexture_0.xnb - 683 kb So I guess my main project sucks there but I couldn't came with a solution. I even tried overwriting my game's content project with new game's content project (which was all okay) but it didn't work. Anybody had similar issues?

• programming can be taken as specialization - but what will I do still unclear [closed]

  - by C4CodeE4Exe

  I am bit confusing about my goals although whole motivation thing is $$$ but still there is something pushing me to pursue higher studies(being frustrated from boot-licking attitudes of peers and lottery system here in India for promotions,pay hikes and onshore opportunities). I am afraid I do not have any goals.I am software developer mainly in JAVA, but an ECE graduate.I want to work in programming languages. My problem is that I am not even Jack of all trades.I have experience in programming and thats where I am good(self-pro-claimed or atleast people say this treating them as a critics). I have decided to go with the wind and applying for programming languages as my specialization.But I know how to code,write test cases,how Perosnal and commercial IT insurances solution works.What I do not know is how to show that what I will do during my masters.I have no idea about what to showcase, how would my work ex will help me. totally oblivious thoughts... thanks waiting for replies....

• What's your advice for getting Oracle Certified Professional Java Programmer certificate?

  - by den-javamaniac

  Hi. I intend to get the certification but am not completely sure how to effectively prepare myself. So I'm wondering if you have any advice on the matter; in particular I would like to know: - What should the basic learning/practicing plan look like? - Which book (set of books) should be considered? - Which practical exercises should be performed? NOTE: I've got several years of corporate experience (mostly web apps, though), but I want to be 100% sure I'll pass the test (that's the reason the issue is raised).

• About to graduage from good school without any progamming skills

  - by newprint

  Not sure if it is good place to ask this question, but found this section to be suitable. I am about to graduate from good school (in the US) with Computer Science degree, having good grades and high GPA. I have no freaking clue how to write a good program, how to properly test it... nada, zero. We were never been tough how to write software. Ye, sure the Comp. Architecture class is important, and I can tell you a lot about how MIPS processor works, and I can tell you about Binary Trees and Red-Black Trees and running time of operations in Big Oh, but it has nothing to do with programming in "real" life. For god sake, none of my classmates know how to use STLs or write templated code !!! To be honest, I found that many of my classes to be waste of time. What should I do ? How to step into real life and learn how to program ?

• Is there a way I can verify my Google Analytics custom report?

  - by SnowboardBruin

  I want to track scrolling on my website since it's a long page (rather than multiple pages). I saw several different methods, with and without an underscore for trackEvent, with and without spaces between commas <script> ... ... ... ga('create', 'UA-45440410-1', 'example.com'); ga('send', 'pageview'); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 100, true]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 75, false]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 50, false]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 25, false]); </script> It takes a day for counts to load with Google Analytics, otherwise I would just tweak and test right now.

• Is programming or computer science in general, all about algorithms?

  - by wakandan

  As a grad student, I find it more and more common for prestigious companies (like Google, Facebook, Microsoft,...) to put algorithm questions in their test and interviews. A few startups I applied to also asked about algorithms. I wonder if algorithms fluency is the most important thing for software developer in those companies? If the answer being yes, what are the best method or resources for one to learn & practice about algorithms effectively? I can't seem to get interested in solving seemingly too complicated problems found in most textbook or websites. Though easily understand basic algorithms (like quicksort, bubblesort,...), I find it immensely difficult to remember and reuse them later. Thanks. P/S: If you ask me what I like, it's building good softwares to solve users' problems innovatively. I suppose that does not necessarily mean the software has to be very complicated.

• Is this a valid HTTP response? [migrated]

  - by fatmck

  I am writing a web server using C++, which responds the following for all requests: static std::string rsp[] = { "HTTP/1.1 200 OK\r\n", "Server: WebServer\r\n", "Content-Type: text/html\r\n", "Content-Length: 3\r\n", "Connection: close\r\n", "\r\n", "123" }; the content "123" can be successfully shown in browser. But when I use apache-ab to do a test, ab always show errors like this: ab -n 1 -c 1 http://127.0.0.1:1080/ apr_socket_recv: Connection reset by peer (104) I thought that I'm closing the socket too quickly, so I commented the close() function. But ab just hold, ab seems to be waiting for a complete response.
