• is OpenID really that bad?

  - by DoPPler

  I have seen this question on Quora where lots of people seem to agree that OpenID is bad, even going as far as stating that: OpenID is the worst possible "solution" I have ever seen in my entire life to a problem that most people don't really have Then I've seen articles and tweets referencing that question saying that OpenID has lost, and Facebook won. It's sad to read as I quite like the OpenID (or at least idea behind it). I literally hate getting yet another login/password for page (I'll forget it anyway) - it's a pretty serious issue for me and I know lots of people with the same problem. Thus I thought that OpenId is a great solution but I'm not sure anymore. So the question is should I still bother to implement OpenID or it's not worth it? What is the most robust and convenient (from the user perspective) way to identify and authenticate an user?

• How to generate `AllowDeactivateGrabs` in command line ?

  - by boffin

  I am using XFCE-Ubuntu and do a lot of my development work there. In my case, when I sometimes use Xilinx ISE, the mouse cursor hangs as a Grab pointer and then stops responding. The entire X environment becomes unusable and I have to kill it and restart. This is becoming a serious annoyance. I saw this bug: AllowDeactivateGrabs is broken I see that sending AllowDeactivateGrabs in command line can kill the Grab. In my case, I am doing this on a remote server, so it is the application in the remote server (over X2GO) getting messed up. I am able to login in command line and kill X. Is there a way to generate AllowDeactivateGrabs in command line ? So I dont mess up my other applications and potentially lose data.

• How do developers find the time to stay on top of latest technologies?

  - by u2sonderzug

  I was a freelance web developer until circa 2004 when I started going down the management route but have decided to try to get back into development again (specifically JavaScript and HTML5 web/mobile web apps) and I really get the impression to be truly good at these and similar fast moving technologies a constant amount of time is required to be set aside to invest in getting better at existing skills in addition to learning new skills. I understand right now since I am getting back into things there is a pretty steep learning curve, but seeing how good many guys are out there - the only way I see of getting up there is putting in a serious amount of time. For those working as fulltime developers, what I am trying to understand is this - on most days, how much time in the office is spent actually grinding out code compared to learning/research. I could easily spend 2-4 hours daily getting on top of the best ways to go about doing things. Do most good developers who are employed full time invest significant hours outside of work sharpening their skills? Or maybe I'm looking at all of this completely wrong?

• How can I apply Readme Driven Development to an ongoing project?

  - by Metalcoder

  I'm assigned to a project where the goal is to update an existing software. This software was developed in a totally ad hoc manner, which means that any documentation generated is outdated, confused and just plain useless. I do not want to retroactivelly produce all the missing artifacts, since this would just be a waste of time. The code base is ugly, and really need some serious refactoring, but this is another story. What I want is to apply Readme Driven Development to guide this project. So, basically, I want to write a Readme, which will document every change meaningful at the user level. The problem is, I have no idea about how to structure this document. For me, it's pretty clear that it should have a different layout than the traditional Readme. I really want to document changes, and not the current state of affairs. Any ideas?

• Last fortnight...

  - by rajeshr

  In the last fortnight, I had an opportunity to meet up with some very energetic folks, who actively participated in a couple of OU programs on Solaris 11 and MySQL. I thank them for their participation and hope all of 'em had a good learning experience showing up for Oracle University programs. As always, I'm publishing below a moment from each of the aforesaid programs. MySQL DBA session in Bangalore. It's unfair if I don't express my heartfelt thanks to each of 'em for a serious teach back session through out the training program and I wish to do so by publishing moments from each one's teach back assignment: Below is a class photograph from Solaris 11 Administration Session in Bangalore.

• Shutdown problem in ubuntu 12.04 LTS

  - by sudeep

  I am using Ubuntu 12.04 LTS and I'm getting a serious bug: When I try to shutdown my system, my screen goes blank but my CPU fan keeps running, i.e. the processor is still working but I am not able to see anything on my screen. I need to power off my machine for a complete shutdown. I am using a desktop with an Intel P4 processor. I found a solution on the internet involving modifying the GRUB config file. But even after doing so I wasn't able to eliminate the issue.

• What can I learn to build a (kind of) recommendation system?

  - by lsmagalhaes

  I'm learning how to develop an android app (nothing serious, just for learning and fun), so I devised the following goal: an app that learns with users actions and, some time later, starts to suggest some useful things. For example: The user add some notes daily, in the morning, and mark some of them as done generally on thursdays and sundays, at evening. Based on that behaviour and the relation of the notes marked as done, the app will prioritize notes that are more propense to be marked, and avoid notifying in days where no note is marked. This is a silly example but I think it ilustrates well what I want to do. I know this is a matter of machine learning, but I don't know where I should start learning. To anyone interested, I'm build a backend in Python, so any libraries or frameworks in this language are very welcome. The frontend, by the way, is sencha touch + phonegap.

• HTML5 / Native / C# & Mono [closed]

  - by iainjames88

  My apologies for the subjective nature of this question but I'm unsure as to which path to follow. I would like to do a bit of indie game development for the iPhone (nothing serious, just something I've wanted to pursue). At my university we aren't taught Java or Objective-C but C#/.NET and HTML5/JavaScript. Is it worth taking what I already know and try to accomplish my goal using, for example, C# and Mono or should I invest the time and learn Objective-C? I don't have a problem learning something new alongside my course (I love learning new stuff) and time isn't a factor. I'm slightly in favor of learning Objective-C for as it would be another string to my bow in the workplace, but it would be nice to stay with C# because it is what I'm used to.

• Why most use Cygwin and not Uwin?

  - by user287424

  Most academic researchers I know target just *nix, and rely on Cygwin to make their applications available on Windows. I have tried many of these projects and always found them too unstable for serious use when running on Cygwin. Uwin looks like a promising alternative to Cygwin. I haven't tried it yet, but I found several comments that it is faster and more stable. However, I haven't seen any use of Uwin to support running *nix apps on Windows. What are the social and/or technical reasons behind Uwin's lack of popularity?

• Game Object Design

  - by oisin

  I'm having a problem with the way I designed my first simple game in C++. I have GameObject (abstract class) and ObjectA which inherits the update() and draw() methods from GameObject. My main loop contains a linked list of GameObject*, and while that list is not empty it cycles through it, calling update on each one. Up until this point, I thought the design was standard(?) and would work. However, when I call update on ObjectA() I run into two problems: ObjectA can die which messes up the list, which in turn throws off the loop in main. ObjectA can spawn more ObjectA's but these are local scope and the update() goes out of scope, creating problems in main's list of GameObjects. I think my design if alright, but I'm having such problems with segmentation faults that there must be something seriously wrong with at least one part of my implementation. If anyone could point out any serious mistakes or simple examples of this being done (or even alternative designs) then I would greatly appreciate it!

• Diminishing Returns - When is it Time to Take Your Website Live?

  Being a perfectionist is not always the best way to be. Especially in a world where being first to market isn't the worst thing ever. Like many things in life, deciding when to take your new website live is a fine balancing act. The sooner you can start building up a readership or client base, the better; but you risk serious damage to your site's reputation if its functional and technical performance is below par. So when is the right time?

• JFileChooser for directories on the Mac: how to make it not suck?

  - by Mike Hearn

  The JFileChooser in "directories only" mode on the Mac has two serious, crippling problems: 1) You cannot create directories with it 2) You cannot switch drives This is rather a huge problem for my installer app. As far as I can tell, Apple provides no way around this problem, you can't even activate the non-native directory chooser ... so the only alternative is to find a free/open source pure-Java replacement widget. Does anybody know of one?

• Theming Drupal Panels

  I created a homepage layout using Panels 3, mostly of blocks created by Views. Now I'd like to apply the visual look and feel as it was designed & sliced. Panels adds an serious amount of divs to its markup. I dont necessarily need to remove this but I do need to add certain classes, id's and change some of the tags used in its markup. What is the best way to go about this?

• j2me MIDP: detecting if phone has a data plan

  - by SB

  Is there a way to determine what kind of data plan a device has so an app provides a less rich experience if a data plan is not available? I imagine the connector factory would still be able to return me an HTTPConnection but it would cost the user serious money for lots of data, and I'd like to be nice and prevent that. I thought there would be a way to query device capabilities in the MIDP API, but maybe it's in CLDC?
