• How to get useful feedback/bug reports from users

  - by Mikael Eliasson

  I'm sure most webmasters have recived a mail like this: Creating [insert item here] is not working! When you check it out there is no general problem with the function but rather the user has discovered an edge case. Almost every mail I get is like this and in the long run it gets a bit annoying to always have to ask the user for more information. Is there anything I can do to get my users provide more useful feedback? Right now I have a mailto: for the webmaster mail in the page footer. I was thinking of changing this so that they have to report through a form on the site. Anyone got any experience with this? Do you get better/more reports by having a feedback form instead of giving the users the email?

• Temporary dimming of desktop in 12.04

  - by deshmukh

  I am running Ubuntu 12.04 (almost default install regularly updated) Unity interface on ASUS X53U (AMD Brazos Dual Core C60 with 2GB RAM). On launching Thunderbird and Firefox, the application dims and the cursor changes to wait mode. In case of Thunderbird, this is most pronounced with the wait time of up to a minute. Memory status checked with free indicates around 500MB of free memory on such occasions. The OS is stable and I can switch to a different work-space, etc. What could this be? Is this something normal?

• How to use OO for data analysis? [closed]

  - by Konsta

  In which ways could object-orientation (OO) make my data analysis more efficient and let me reuse more of my code? The data analysis can be broken up into get data (from db or csv or similar) transform data (filter, group/pivot, ...) display/plot (graph timeseries, create tables, etc.) I mostly use Python and its Pandas and Matplotlib packages for this besides some DB connectivity (SQL). Almost all of my code is a functional/procedural mix. While I have started to create a data object for a certain collection of time series, I wonder if there are OO design patterns/approaches for other parts of the process that might increase efficiency?

• A Simple Solution For NetBeans RCP Apps That Need A Groovy Editor

  - by Geertjan

  Take a look at Nils Hoffmann's metabolomic analyzer, especially at the Groovy editor contained within it: Obviously, it would be cool if the Groovy editor in the app above were to have syntax coloring and other editor features helpful in coding Groovy. However, as I showed in If You Include the Groovy Editor, there are multiple dependencies that the NetBeans Groovy support has on other modules that would be completely superfluous in the above application, while they'd make the app much heavier than it is, simply because of all the Groovy dependencies. But today I thought of a simple solution. Why not take the Groovy.g file (i.e., the ANTLR definition), such as this one [though that's probably not the most up to date one, wondering how to find the most up to date one] and then apply the content of this screencast (made by me) to the Groovy.g file: Within a few minutes, you should end up with Groovy syntax coloring. OK, so that's not a full blown Groovy editor, but syntax coloring is surely a cool thing to have in the app with which this blog entry started? Sure, this means creating a new Groovy editor from scratch. But the point is that doing so can be very simple, i.e., the syntax coloring can simply be generated via the simple instructions above. I'm going to try it myself in the next few days, but would be cool if others out there would try this too!

• Make blogger load faster

  - by Wladimir Ivanov

  all. I use blogger as a platform for electronic music blog. Because of the thematics of the blog I embed many iframes (Youtube & Soundcloud). Of course this makes the articles to load slow. Almost each article on this blog consists of some text and many iframes below. What should I do in this particular case in order to make the articles (pages) load faster. Is there any available solution or I should use some jquery like lazy load to load iframes once the scroller reaches them? Any help is greatly appreciated.

• Why is the Touchpad tab missing?

  - by U47

  So my Dell Vostro 3360 came out of the box with an Alps touchpad which was detected as PS/2. Through these steps, I was able to get as far as it appearing to be recognized as a touchpad. Howevver, I do not get the Touchpad tab in the Mouse/Touchpad settings. Two-finger scrolling appears to work, and the Fn-F3 does disable the touchpad, but the settings are so brutal that it is almost impossible to work with. Very difficult to scroll at all accurately. I'm hoping there's some settings which can be tweaked which will help with this. Any ideas? My xinput listing is as follows: ? Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ? GlidePoint Virtual Touchpad id=12 [slave pointer (2)] Thanks,

• SharePoint Client Object Model: Step One

  - by PeterBrunone

  I almost didn't make it out alive.  I followed the instructions in every piece of sample code and every forum post by someone who had no idea why their client OM code wasn't working, and my code still wouldn't get past the page load.  I kept getting "'Type' is undefined" errors when sp.core.js tried to register the SP namespace.As it turns out, you need the help of the default master page (or one like it) to get the object model loaded.  Once I told my sample page to use the default master and modified everything accordingly, it hooked up and ran just fine.Now I can finally get some work done.

• Should a poll framework be closed sourced

  - by samquo

  I was having a chat with a coworker who is working on a polling app and framework. He was asking technical questions and I suggested he open source the application to get more quality opinions from developers who are interested in this problem and are willing to give it heavy though. He has a different point of view which I think is still valid so I want to open this question for discussion here. He says he believes something like a polling framework should not be open sourced because it will reduce its security and validity as people reveal loopholes through which they can cheat. Can't say I completely disagree. I see a somewhat valid point there, but I always believed that solutions by a group of people are almost always better than a solution thought by a single person asking a small number of coworkers, no matter how smart that person is. Again I'm willing to accept that maybe some types of applications are different. Does anyone have an argument in his favor? I'd really like to present your responses to him.

• Google webmaster tools / Geographic location settings

  - by JochemTheSchoolKid

  I am building an website. It has an .nl domain. Now only my domain is showing up on google.nl I hope I can change this somehow that it could be findable in all google's (like google.com / co.uk) and so on. If I look on google forums. They say go to webmaster tools and change your geographic position over there. But I have added this site and I am not able to change it there because there is no select box. I dont have any idea were to search (yes I searched on google offcourse) or where to ask for this special problem. So maybe here can someone redirect me or explain me what is possible and what not. The question is can I make an .nl domain findable in (almost) all google search sites? And so on how can I do that. Picture of my google webmaster tools (nl): http://i.stack.imgur.com/ZuP4L.png

• Testing Reference Data Mappings

  - by Michael Stephenson

  Background Mapping reference data is one of the common scenarios in BizTalk development and its usually a bit of a pain when you need to manage a lot of reference data whether it be through the BizTalk Cross Referencing features or some kind of custom solution. I have seen many cases where only a couple of the mapping conditions are ever tested. Approach As usual I like to see these things tested in isolation before you start using them in your BizTalk maps so you know your mapping functions are working as expected. This approach can be used for almost all of your reference data type mapping functions where you can take advantage of MSTests data driven tests to test lots of conditions without having to write millions of tests. Walk Through Rather than go into the details of this here, I'm going to call out to one of my colleagues who wrote a nice little walk through about using data driven tests a while back. Check out Callum's blog: http://callumhibbert.blogspot.com/2009/07/data-driven-tests-with-mstest.html

• Advice: How to convince my newly annointed team lead against writing the code base from scratch

  - by shan23

  I work in a pretty reknowned MNC, and the module that I work in has been assigned to a new "lead". The code base is pretty huge (~130K or more, with inter dependencies on other modules) , but stable - some parts have grown ugly over the years, but its provably in working state. (Our products are running for years on them, even new ones). The problem is, our lead wants to rewrite the code from scratch, to encompass "finer granularity and a proactive design". I know in my guts thats not a very good idea, but how do I convince him/the rest of the team(who are pretty much more senior than me in terms of years of exp), without sounding too pedantic myself (Thou shalt not rewrite , as Joel et al have clear articles prohibiting it)? I have a good working relation with the person concerned, and don't want to ruin it, but neither do I want to be party to a decision which would surely plague us for years to come !! Any suggestions for a milder,yet effective approach ? Even accounts of how you have tackled such a situation to your liking would help me a lot! EDIT: The code base I'm talking about is not a product/GUI, but at kernel level with all the critical functionalities for our product. I hope now you know why i sound so apprehensive !!

• fix pavucontrol Alsa mixer with creative card

  - by schwiz

  I have been desperately trying to get my creative x-fi soundcard to work with my 10.10 install and I am almost there! I have 1 speaker working and when I open volume control I see that my device is Creative X-fi (Also mixer). However, it appears to be stuck on mono. When I open pavucontrol I get a message that says Connection failed: Connection refused and it exits. Before it closes I can see that playback is set to mono but it won't let me change before it closes. Can someone help me over this last hump? I am running 32 bit 10.10 any advice is much appreciated.

• https:// search results appearing on Google for purely http:// site

  - by hydrurga

  I started weeding through my site's search results from Google today, using a site: search, to determine if there are any links that cause 404s and thus need redirecting. To my amazement I noticed numerous https:// results relating to various pages. My site doesn't have a SSL certificate, doesn't serve such pages, doesn't internally link to https:// pages, doesn't include any such files in its sitemap.xml and, for all of these, never has. I decided to do a Google search for https://<my site> and found one site that incorrectly refers to the root of my site with a https:// prefix - I will try to contact them to get them to correct this. I'm not sure however how Googlebot managed to index the non-root files as https://. I can't find any external links to them and surely, without certification, Googlebot should have stalled at the first request? I've just added the following lines to the site's .htaccess (although the surfer still has to navigate through the browser's "This site is a security risk. Abandon hope all ye who enter here!" message(s) first to get there): RewriteEngine On RewriteCond %{HTTPS} on RewriteRule ^(.*)$ http://www.<my site>.org/$1 [R=301,L] replacing <my site> with my domain name. My big question is this though - I would like to use the Google Webmaster Tools Remove URLs feature to remove the https:// pages from the index. Can I be guaranteed that this will only remove the https:// versions of each relevant page and not the valid http:// versions? My thanks to anyone who can help me out with this particular question and the issue in general.

• Solutions for software using many calls to a server

  - by Val

  I am developing software that uses many calls to a server. On a client side it's a Silverlight application. Almost every time a user clicks on a button in it, it sends 1-5 WCF calls to a server. There can be up to dozen or so users at a time. The server is a database server that serves data to a client. I am an intermediate level developer and am thinking about caching some data and syncing my changes from time to time. Are there any official solutions or technologies for it, like, patterns and such?

• Proprietary Driver missing after Kernel upgrade

  - by Chris

  I recently upgraded my kernel to the Linux 3.4 kernel. Upon doing so, I found that it zapped my proprietary driver for my graphics card. As an alternative, I had saved Catalyst 12.8, but now it will not open through Software Center. I tried several other terminal methods, but it seems that many of these postings are bunk. They only work until you're almost done and then you get errors. I just need a little help from somebody who has been there, as I am new to Ubuntu. I'm kind of afraid to reboot because this is my 3rd full load of Ubuntu. Any ideas?

• Are there non-programming related activities akin to solving programming problems ?

  - by julien

  I'm talking about particular activities, for which you can draw parallels with the specific kind of reasonning needed when solving programming problems. Counter examples are activities that would help in almost any situation, like : take a shower or any other, somewhat passive activities, which are only helpful in triggering this sort of asynchronous problem solving our brain does exercise, because you brain simply works better when you're fit EDIT : It seems this question was quite misunderstood. I wasn't asking about what you can do when stuck on a problem but rather, what kind of activities you have in you spare time that you think help you, more or less directly, solving programing problems.

• Programming languages similar to ActionScript 3 / EcmaScript based

  - by Juanlu001

  I almost learned programming and OOP basic concepts with ActionScript 3 on the Flash Platform years ago. Some time has passed since then; I'm not a professional programmer, but I have written code in PHP, Fortran, and now Python. But, lately, I have missed ActionScript 3 OOP implementation, static typing and, I confess, curly braces. As Flash platform is slowly dying nowadays, I'm looking for an Open Sourced programming language similar to ActionScript 3. I've read about Java, which is the most similar one I found, but actually is the only one it doesn't interest me (I started to hate it after bad experiences with web applets). Any ideas? Edit: Added EcmaScript to the title and the tags; I think that is what I am looking for.

• Why doesn't my IDE do background compiling/building?

  - by MKO

  Today I develop on a fairly complex computer, it has multiple cores, SSD drives and what not. Still, most of the time I'm programming the computer is leasurely doing nothing. When I need to compile and run/deploy a somewhat complex project at best it still takes a couple of seconds. Why? Now that we're living more and more in the "age of instant" why can't I press F5 in Visual studio and launch/deploy my application instantly? A couple of seconds might not sound so bad but it's still cognitive friction and time that adds up, and frankly it makes programming less fun. So how could compilation be instant? Well, People tend to edit files in different assemblies, what if Visual Studio/The IDE constantly did compilation/and building of everything that I modified anytime that it might be appropriate. Heck if they wanted to go really advanced they could do per-class compilation. The compilation might not work but then it could just silently do nothing (except adding error messages to the error window). Surely todays computer could dedicate a core or two to this task, and if someone found it annoying it could be disabled by option. I know there's probably a thousand technical issues and some fancy shadow copying that would need to be resolved for this to be seamless and practical but it sure would make programming more seamless. Is there any practical reason why this scenario isn't possible? Would the wear and tear of continually writing binaries be too much? Couldn't assemblies be held in memory until deployed/run?

• How do you track bugs in your personal projects?

  - by bedwyr

  I'm trying to decide if I need to reassess my defect-tracking process for my home-grown projects. For the last several years, I really just track defects using TODO tags in the code, and keeping track of them in a specific view (I use Eclipse, which has a decent tagging system). Unfortunately, I'm starting to wonder if this system is unsustainable. The defects I find are typically associated with a snippet of code I'm working on; bugs which are not immediately understood tend to be forgotten, or ignored. I wrote an application for my wife which has had a severe defect for almost 9 months, and I keep forgetting to fix it. What mechanism do you use to track defects in your personal projects? Do you have a specific system, or a process for prioritizing and managing them?

• how do you remember programming related stuff?

  - by dan leadgy

  How do you remember programming related stuff? Did you get the feeling you did encounter the error you have now a few years ago and you could swear you knew the cause but now you forgot it? Did you work with the xsl's string parsing some time ago but now you can't remember exactly which are the string functions altogether from xsl and you have to start from scratch? Or perhaps you forget about some feature from Apache Commons like "filtering a collection by some predicate" that you surely used in the past. So how do you do it? I tried having a blog but when I develop apps, I never find the time to update the blog or write about my experiences. Also, using a wiki is a nice thing but then I found it difficult to keep a clean separation between them since many times I needed to change a blog post to add new information about that topic. This made me think that I actually should have put this topic in the wiki instead of the blog. Do you have any systems that help you remember about your programming experience? What's your setup?

• GLIBC_2.8 not found

  - by Thomas Nilsson

  As a newbie I seem to have messed up my upgrade leaving my system in a very unstable state. I attempted an upgrade from 8.04LTS which ended in an error about libc and kernel upgrades. I tried to upgrade the kernel but am now unsure if that worked, because when I retried my dist-upgrade there was a lot of errors about pre-dependencies and leaving packages un-configured. Now I have a system that answers almost every command with: /lib/libc.so.6: version `GLIBC_2.8' not found (required by /lib/libselinux.so.1) I probably should try a complete re-installation, but I'm investigating if there is any possibility of getting a working glibc so that I at least can have some commands working to ensure that my backups are recent etc. before doing the clean install. not even 'ls' works without saying "glibc_2.8 not found".

• Happy Birthday Java EE 6+GlassFish 3!

  - by reza_rahman

  It has been almost exactly three years since Java EE 6 and GlassFish 3 were announced. It's worth pausing a moment to take stock of what has happened since. Both Java EE 6 and GlassFish 3 have been game changers. EE 6 has brought Java EE back in the limelight. To see evidence of that look at presentations like these from independents like Bert Ertman and Paul Bakker: JavaOne 2011: Migrating Spring Applications to Java EE 6 from ertmanb Likewise, the GlassFish community has proven to be a powerful disruptive force in the Java application server landscape. It's impact is evident from this percent growth rate chart from indeed.com of major Java application servers: Please join us in wishing both GlassFish and Java EE a very happy birthday and many more to come with Java EE 7, GlassFish 4 and Oracle's capabale stewardship...

• how can I get 32-bit program to run on 64-bit Ubuntu?

  - by Carol

  Sorry to be asking this, but I have read quite a few posts and articles a lot of places wrt the issue I am having, to no avail. I am trying to get a Second Life Viewer (Firestorm) to run, and just keep getting the '64-bit error message' it throws. I have installed every 32-lib I can find, still doesn't work. I think I am surely missing some setting somewhere, or running Firestorm from the wrong place, or something, but I have no idea what. FWIW, Firestorm loads but doesn't behave right in the 32-bit version, either. I have actually tried several linux distros, 32 and 64-bit. Mint 32-bit runs it straight off, and Mint 64-bit throws the '64-bit error'. openSUSE, any version, won't run it at all. Oh, and all the other SL viewers I have tried behave the same way. I am beginning to wonder if my set-up just doesn't like linux. Here is my system info: CPU: Intel(R) Core(TM) i5 CPU 750 @ 2.67GHz (2661 MHz) Memory: 4026 MB OS Version: Linux 3.2.0-29-generic-pae #46-Ubuntu SMP Fri Jul 27 17:25:43 UTC 2012 i686 Graphics Card Vendor: ATI Technologies Inc. Graphics Card: ATI Radeon HD 5700 Series I appreciate any help anyone can give me! Thanks so much! Carol :)

• What constitutes proper use of threads in programming?

  - by Smith

  I am tired of hearing people recommend that you should use only one thread per process, while many programs use up to 100 per process! take for example some common programs vb.net ide uses about 25 thread when not debugging System uses about 100 chrome uses about 19 Avira uses more than about 50 Any time I post a thread related question, I am reminded almost every time that I should not use more that one thread per process, and all the programs I mention above are ruining on my system with a single processor. What constitutes proper use of threads in programming? Please make general comment, but I'd prefer .NET framework thanks EDIT changed processor to process

• Repacked proprietary software keeps updating the same deb

  - by Johannes

  I repacked a proprietary program delivered as tar file to a deb file for having a company wide repository. I used reprepro to set up a repository and signed it. A unix timestamp is faking a versioning numbering, so I can have different (real) versions installed at the same time. Almost everything works as expected. The deb file looks like this: mysoft8.0v6_1366455181_amd64.deb Only problem on a client machine it tries to install the same deb file over and over again because it thinks its an update. What do I miss: control file in deb package looks like this: Package: mysoft8.0v6 Version: 1366455181 Section: base Priority: optional Architecture: amd64 Installed-Size: 1272572 Depends: Maintainer: me Description: mysoft 8.0v6 dpkg repackaging and the config in the repository: /mirror/mycompany.inc/conf/distributions: Origin: apt.mycompany.inc Label: apt repository Codename: precise Architectures: amd64 i386 Components: main Description: Mycompany debian/ubuntu package repo SignWith: yes Pull: precise Help much appreciated Added guide: This Is the guide I used to create the repository.
