• Why does Perl's Crypt::SSLeay timeout on Intel Mac OS X machines?

  - by Joe

  A have a Perl cron job that recently started having its HTTPS connections start failing with an error of "500 SSL read timeout". I've tracked that the error is being thrown as part of an alarm in Crypt::SSLeay, but I don't know if this is simply something taking too long to respond. So far, I've adjusted the timeout from the default 30 seconds to 10 minutes and it still times out. I've moved the script to other machines, and those on Intel Mac OS X systems all time out, while those under Linux, or on PPC Mac OS X systems run fine, so I don't think it's changes on the network or remote server. When the process started having problems does not coincide with any software updates or reboots on the machine, and I've contacted the server I'm connecting to, and everyone claims that they haven't changed anything. Does anyone have recommendations on trying to debug HTTPS, or have you ever seen this behavior and give recommendations on something I might've overlooked at that could've caused this problem?

• 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?

• Check if a php script is running

  - by Nirmal

  I have a script that listens to a jabber server and responds accordingly. Though it's not supposed to stop, last night it did. Now I want to run a cron job every minute to check if the script is running, and start it if not. The question is, how do I check if a particular script is still running? Some solutions have been posted here, but those are all for Linux, while I am looking for a Windows solution. Any ideas please? Thanks.

• the best "Simple" CMS system suitable for .Net MVC

  - by Truegilly

  Hello, I'm developing a MVC .Net site and would like to implement a CMS system. So far I have looked at Umbraco, which looks good but the help is poor and the getting started video section is empty, and dotnetnuke, which again looks good but I get the impression its aimed at non developers, plus to has much more than I need and want. In my last job I created a basic custom CMS system that worked by simply adding values into the database, the application called the text from there. it worked fine but I don’t have the source code. what I'm after is a simple CMS system that really just controls text and images, I dont need all the fancy stuff thats in umbraco and dotnetnuke, all the design and CSS i can do myself. also as im working with MVC (which is awesome, and such a breath of fresh air compared to the web forms/telerik crap I have to put up with at work) it needs to be compatible. A simple CMS, can anyone provide any suggestion ? Truegilly

• JavaScript or Qt way to update a select box value?

  - by Pirate for Profit

  So I have the following HTML and am trying to change which item is selected. <select name="coolselectbox"> <option value="default" selected="selected">---</option> <option value="something">Something</option> <option value="something-else">Something Else</option> </select> Here's what I've tried: QWebElement defaultOpt = this->page()->mainFrame()->findFirstElement("option[value=default]"); QWebelement somethingOpt = this->page()->mainFrame()->findFirstElement("option[value=something]"); defaultOpt.removeAttribute("selected"); somethingOpt.setAttribute("selected", "selected"); And then also: QWebElement selectBox = this->page()->mainFrame()->findFirstElement("select[name=coolselectbox]"); selectBox.setAttribute("value", "something-else"); However neither of these seems to get the job done. Does anyone know a Qt solution, or is there perhaps some JavaScript snippet I can run to do this?

• The equivalent of this Perl regex in PHP

  - by Jamie

  Hi all, What would be the equivalent in php of this regex in php: I.e. which function would do the same job. if (/^([a-z0-9-]+)\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)$/ and $1 ne "global" and $1 ne "") { print " <tr>\n"; print " <td>$1</td>\n"; print " <td>$2</td>\n"; print " <td>$3</td>\n"; print " <td>$4</td>\n"; print " <td>$5</td>\n"; print " <td>$6</td>\n"; print " <td>$7</td>\n"; print " <td>$8</td>\n"; print " </tr>\n"; } Thanks very much! :-)

• array_merge vs array_value for resetting array index

  - by Jamex

  I have 1 array that I want to re-index. I have found that both array_values and array_merge functions can do the job (and I don't need 2 arrays for the array_merge function to work). Which is faster for a very large array? I would benchmark this, but I don't know how and don't have the large array yet. Before re-index: Array ( [0] => AB [4] => EA [6] => FA [9] => DA [10] => AF ) After re-index: Array ( [0] => AB [1] => EA [2] => FA [3] => DA [4] => AF )

• Devising a test strategy

  - by Simon Callan

  As part of a new job, I have to devise and implement a complete test strategy for the companies new product. So far, all I really know about it is that it is written in C++, uses an SQL database and has a web API which is used by a browser client written using GWT. As far as I know, there isn't much of an existing strategy, except for using Python scripts to test the web API. I need to develop and implement a suitable strategy for unit, system, regression and release testing, preferably a fully automated one. I'm looking for good references for : Devising the complete test strategy. Testing the web API. Testing the GWT based application. Unit testing C++ code. In addition, any suitable tools would be appreciate

• How to get an internship with a low GPA?

  - by Jason Baker

  A lot of changed majors and some other mitigating circumstances have left me with a pretty low GPA. My GPA in the last couple of semesters hasn't been stellar, but my grades have gotten a LOT better. I want to try and start putting in some resumes to get a good internship this summer. I do think that I have some decent experience for someone at my level, but I see my GPA being a pretty big potential stumbling block. Is there anything I can do to help my chances of getting a good internship? (For the record, the mitigating circumstances aren't something I'd feel comfortable discussing with a potential employer. I'd prefer getting a job by proving my merit, not making excuses.)

• Is it possible to destroy a CDI scope?

  - by Matt Ball

  I'm working on a Java EE application, primarily JAX-RS with a JSF admin console, that uses CDI/Weld for dependency injection with @ApplicationScoped objects. Minor debugging issues aside, CDI has worked beautifully for this project. Now I need some very coarse-grained control over CDI-injected object lifecycles. I need the ability to: Remove an injected object from the application context, or Destroy/delete/clear/reset/remove the entire application context, or Define my own @ScopeType and implementing Context in which I could provide methods to perform one of the two above tasks. I'm fully aware that this is across, if not against, the grain of CDI and dependency injection in general. I just want to know Is this remotely possible? If yes, what is the easiest/simplest/quickest/foolproofiest way to get the job done?

• Ways to divide the high/low byte from a 16bit address?

  - by Grissiom

  Hello, I'm developing a software on 8051 processor. A frequent job is to divide the high and low byte of a 16bit address. I want to see there are how many ways to achieve it. The ways I come up so far are: (say ptr is a 16bit pointer, and int is 16bit int) ADDH = (unsigned int) ptr >> 8; ADDL = (unsigned int) ptr & 0x00FF; and ADDH = ((unsigned char *)&ptr)[0]; ADDL = ((unsigned char *)&ptr)[1]; Does anyone have any other bright ideas? ;) And anyone can tell me which way is more efficient?

• a quick overview on access

  - by masfenix

  Hey I am a university student (math major), but programming since I was little (read: 14). I am starting a new programming job tomorrow at a very big company. However I just found out that I might be just working with access for a couple of weeks (macros and whatnot). Can someone just give me a general rundown on how to create and use VB in access. What I mean is how do tables refer to themselves (as objects? as what name?) how to run queries through vb and such. thanks all.

• Is Work Stealing always the most appropriate user-level thread scheduling algorithm?

  - by Il-Bhima

  I've been investigating different scheduling algorithms for a thread pool I am implementing. Due to the nature of the problem I am solving I can assume that the tasks being run in parallel are independent and do not spawn any new tasks. The tasks can be of varying sizes. I went immediately for the most popular scheduling algorithm "work stealing" using lock-free deques for the local job queues, and I am relatively happy with this approach. However I'm wondering whether there are any common cases where work-stealing is not the best approach. For this particular problem I have a good estimate of the size of each individual task. Work-stealing does not make use of this information and I'm wondering if there is any scheduler which will give better load-balancing than work-stealing with this information (obviously with the same efficiency). NB. This question ties up with a previous question.

• Internet and Intellisense bad for your memory?

  - by Barry Jones

  Having programmed for a while now I have noticed that I am becoming more and more reliant on the internet and intellisense to do my job. But I was wondering how much that has effected my knowledge over the past year or so. But does this matter? For example I am more likely now to remember that when I need to program against objects I have no knowledge about, I will go to the System.Reflection namespace and a quick look down the list will provide me with enough detail to get going again. But if you was to ask me which classes etc are required I would struggle to name them all. This problem of remembering seems to manifest itself more when going for interviews when people seem to focus more on the minute detail of obscure areas of the .NET framework and not on the wide and varied knowledge and experience of the applicant. Anyway I digress. Does anyone else think that maybe its time to turn of the intellisense and try and find better ways to learn, then quick fixes and work arounds of the internet?

• Open Source CMS with linked sub-sections and users

  - by Teegijee

  I work at a small college that wants to make "sites" for all of the academic departments (~30). I managed to talk them out of their original idea: 30 individual Wordpress installations. What a maintenance nightmare! What I'm looking for is a CMS (preferably Python or PHP, as those are my areas of expertise) that can automagically create a subsection (or subsite, whatever the appropriate vernacular) complete with user and a couple of headings based on a template. So, I could just click a button and have a new subsection for a new department complete with its own authorized user, and default subsection headings/menu/pages. Is this just wishful thinking? I don't mind getting my hands dirty (this would be the whole of my job duties), so what platform would be a good starting point for something like this? Open source is a must for me as I have literally no budget, and I'm probably going to have to dig pretty deep into the application.

• Is using an OS's functions for retrieving file content type reliable (using PHP < 5.3)?

  - by letseatfood

  I am using PHP versions < 5.3. Is it reliable to use the OS's functions for retrieving file content types? I am just trying to make sure that files are of a specific type before displaying them in a browser. I don't want to rely on just using the file extension. mime_content_type() is deprecated and I do not have the PECL Fileinfo extension. In my case I am using Windows or Linux for my development servers, depending on the job.

• Scrum metrics for quality

  - by zachary

  What is the best way to measure QA in scrum? We have members who typically test and they are measured against how many bugs they find. If they don't find any bugs then they are considered to be doing a bad job. However, it is my understanding that the developers and quality people are considered one in the same. I would think that they should be judged against the same metrics... not different metrics then the developers who may also be doing testing work... What is the best way to handle metrics for QA and should QA people have separate metrics from developers in scrum? Any documents or links someone can point me to in regards to this?

• How has test first development changed the way you write software?

  - by Toran Billups

  I've started to find that I can't write software without writing a test first. I ask this subjective question because I want to hear what others in the community think about the reasons I can't go back to writing production code without a test first. If you can't write a test for something you don't understand it Without a regression test you can't clean the code You are going to test it anyway, spend the time to do it right Evolutionary design is possible without fear You actually write less code yourself Fast feedback cycles save time and money Job security (less bugs makes your boss happy) It actually makes my work more enjoyable

• Text code decoding

  - by Diana Villafane

  Hello. I am an English/Spanish Spanish/English translator. I have been given a job where I have to translate Spanish text messages sent from cell phones. Some of them are in code. I assume each set of figures represents a letter. Is there any website where I can find information on how to decipher the code? For instance, the first message says: ‘0x69 ox61 0x6e 0x70 0x72 0x2e 0x6e 0x65 0x74 0x2f 0x3f 0x64 0x34 0x39 0x31 0x66 0x30 0x37 0x38 0x35 0x35 0x32 0x39 0x62 0x36 0x31 0x31 0x00 Thank you for any help you provide.

• Images saved with D3DXSaveSurfaceToFile will open in Paint, not Photoshop

  - by bsruth

  I'm using D3DXSaveSurfaceToFile to save windowed Direct3D 9 surfaces to PNG, BMP and JPG files. There are no errors returned from the D3DXSaveSurfaceToFile call and all files open fine in Windows Photo Viewer and Paint. But they will not open in a higher end image editing program such as Paint Shop Pro or Photoshop. The error messages from these programs basically say that the file is corrupted. If I open the files in Paint and then save them in the same file format with a different file name, then they'll open fine in the other programs. This leads me to believe that D3DXSaveSurfaceToFile is writing out non-standard versions of these file formats. Is there some way I can get this function to write out files that can be opened in programs like Photoshop without the intermediate step of resaving the files in Paint? Or is there another function I should be using that does a better job of saving a Direct3D surfaces to an image?

• Integrating TFS and MySQL

  - by user294043

  We are developing an application with Visual Studio 2008 and TFS. Our database is a MySQL DB. As we develop we keep the new queries that need to be applied to the database of our new release as the New Version Update Queries. Right now I'm keeping them in a simple text file (which is a painful task!). I know that TFS integrates with MSSQL and makes this job very easy. I've already asked our consultant from Microsoft if there is any way to integrate TFS and MySQL, and his answer was "NO". So I was wondering if anyone knows any smart way of handling this issue?
