• why does our network printer not show up on some of our macs, but does show up on others? [on hold]

  - by peter

  We lost power in our building and now cannot get our HP laser jet 5200 to be recognized by half of our computers. We are all Macs, some running OS 10.7.5 can see the printer, others running 10.7.5 cannot, and those running 10.8.5 and 10.9 cannot. We've re-booted the router, turned off and on printer and macs—no go. The printer displays an IP address (dynamically assigned) but we can't access it. Tried to see it using CUPS—same story, can see it on some systems, not on others. Any thoughts?

• Firefox released beta 9 for version 4

  - by anirudha

  Firefox yesterday released 9 beta of Firefox 4. now many plug-in work inside Firefox 4. How to get plugin work in Firefox 4 :- if you like any plug-in who you like to use but not worked in Firefox 4 go to developer site may be they work on them so it’s chance you can get the version who is in development from developer site. because many of plugin wait for a time period for testing or making same version for all plateform like linux or mac osX. How to work with stable and Beta version [standalone] sometime we fell that it’s time wasting because something we need the beta version can’t give. so you can use Firefox 3.6.13 or Firefox 4 both by a trick. you need to install them in other directory. when you trying to install another version beware because they also override the last installation directory so you need to choose the directory where you want to get another version manually.

• What IRC client(s) would allow me to filter out log messages?

  - by Aras

  I have been using Empathy and more recently Pidgin as my IRC client. But there is one feature missing from both of these clients that keeps bothering me. I want to be able to see only what people are actually talking about in each channel. I often like to leave IRC channels open and go back to them and read the messages for the last few hours or days. I saw that IRC clients have been discussed in this post and a few others, but I have not found what I am looking for yet. Here is what I want to see in my IRC client: what actual people say Here is what I do not want to see message about people entering the room people leaving room people changing their status messages or what they are known as people sneezing people's cats sneezing Anyway, you get the picture. What IRC clients are available for Ubuntu that would allow me to configure what I see so that I can see what people are talking about -- and nothing else?

• What Shading/Rendering techniques are being used in this image?

  - by Rhakiras

  My previous question wasn't clear enough. From a rendering point of view what kind of techniques are used in this image as I would like to apply a similar style (I'm using OpenGL if that matters): http://alexcpeterson.com/ My specific questions are: How is that sun glare made? How does the planet look "cartoon" like? How does the space around the planet look warped/misted? How does the water look that good? I'm a beginner so any information/keywords on each question would be helpful so I can go off and learn more. Thanks

• What is the the best way to become an iPhone developer?

  - by Noah89

  I have no experience as a programmer but I'd like to become a iPhone developer. Some people tell me to learn java because it is a Object Oriented Language. Other people tell me to go with C++. However, everyone advises me to actually learn any language and learn what programming is all about before I actually develop for iPhone. Please, let me know what would be the best choice and what books would be good for a total beginner and any website that offers any good tutorials. Thanks in advance for all the feedback.

• Development methodology for single web developer?

  - by CaseTA

  I'm a web developer who mostly works with the LAMP stack when it comes to my own projects. Most of the time I just start coding on a project and fixing bugs and adding features as I go along. Often I'll try to use an existing solution such as Wordpress or Drupal. Now that I'm thinking of creating my own web application with businesses as the target group, I feel there's a need for proper analysis and design. Something lightweight for a one person project and still solid enough to handle requirements, user interfaces, security, etc. If you could recommend methodologies and literature I would be grateful.

• Disable "Ubuntu 14.04" and "Files" from auto sorting alphabetically and THEN<(Disable the then.) automatically going to that location

  - by Doodski Man

  I looked about in Ubuntu 14.04 and I could not find a option to disable a feature that made extra work for me. After renaming something "Files" then reorganizes alphanumerically and then automatically moves the prompt/cursor/highlighting to the new file name at the new alphanumerical location. It's much easier and practical if the working cursor remains in the same area where the file was found that needed name changes or needed name spelling corrections. Windows 7 does what I ask about and it's a huge improvement over that auto sort and then go to the new file location. A example to consider is a file is in the "A" area and then you rename it to a "Z" and you are then taken to the "Z" stuff and need to scroll hundreds of lines back to the "A" section. It's annoying. Thanks for reading and taking the time.

• Can we 301 redirect to a new page, but still publish the old content somewhere else?

  - by KBS

  We have a page on the site which ranks well for an SEO term (top 5) but contains old information. We have added a new page but Google doesn't rank it that well. Information on these pages is time sensitive. Old: example.com/2013-related-information.html New: example.com/2014-related-information.html Obvious solution is to delete old page and do a 301 redirect to the new page. Now, can we still keep the old page by giving it a new URL. example.com/2013-related-information.html is redirected to example.com/2014-related-information.html example.com/2014-related-information.html is recreated with a new address such as example.com/new-2013-related-information.html What we are trying to do is to send the user to the fresh page but still not destroying the record copy if someone wants to go and dig up the old information.

• Continuing to code on large projects

  - by user3487347

  I am a hobbyist programmer, and I've started many medium - sized projects to work on just by myself. These include games, a raytracer, physics simulations etc. By the time these projects get to a certain size (around 5000 lines), I begin to slow down in adding features to the program. This is not because of a lack of ideas of what to implement in a program, but rather a struggle in how to go about it. In particular, I'm afraid of breaking what I already have working in order to implement a new feature. I've tried using version control like Git and Subversion, but these seem unnecessary when you are a one man team. I simply have a folder of "versions" of my program, one for each major change I make. How do I keep coding past this 5000 line mark? What about the 50000 line mark?

• Is there a way to determine if a database has been altered, then to push new data to the Application

  - by TeamGB

  All our (my company) currently applications pull information from that database, is their a way to get the following types of databses to either push data or push an event to allow the application to pull data. Access SQL Oracle File systems (Files and folders) The issue today is that most of our application spend a large amount of time constantly looking at databases and file system checking to see if data has changed . It would be better for the database to inform the application when data has changed. Are there tools within Visual studio to allow this or are there tools within the database / filesystem to do this? All ready asked this on stack overflow but go no answer. I've been doing some more research but I cant seem to get any further. My manager has asked to investigate it as it would mean our applications are much quicker and efficient.

  I installed Starcraft II wings of liberty via playonlinux, it installed fine, it starts up fine, but when I go into a game the map does not show, it is just black, but all my buildings/units/mineral line shows up, but everything else is black, also all the abilities do not have any graphics, and I can not see my player portrait in the menus.

Can anyone help? Thank you in advance!

• Need your opinion: which domain should I use for the blog?

  Reader new to my blog might have wondered why blog lives in a .NZ domain: to make a long story short is because when I started my blog I was soo excited about my relocation to New Zealand that I registered a .NZ domain. Then I came back to Italy, and started to work in Milano. Last autumn I had to chance to go back to New Zealand again, but at the same time the offer to work for an European Institution arrived. And then my .net.nz domain didn't make sense any more. And because it seems like I've...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Technical website - Should I assume that my visitors will use a modern browser?

  - by marco-fiset

  I am in the process of creating my own website, which will include a technical blog. I want to build my website using modern technologies such as HTML5 and CSS3. Since my website will be targetted at programmers and mostly tech-savvy users, should I take for granted that these people will be using a modern browser? Or should I make my site compatible with older browsers just in case? I don't want to go through the pain of adapting my website to be compatible with browsers I assume won't be used.

• Upgrade to Ubuntu 13.10 disabled track pad, brightness, sound on Lenovo Z570

  - by Vizir

  I just upgraded to Ubuntu 13.10 using Ubuntu's software update. It seemed to go all right, however after the system restarted and booted up Ubuntu 13.10, it began experiencing several problems. Some of them were due to expected conflicts with the updated OS, however right now I cannot figure out why certain hardware functions are now "broken" and how to fix them. As far as I can tell, these are the sound (permanently muted), mic (picks up no sound), brightness (set at maximum brightness regardless of using keyboard shortcuts or moving the screen brightness slider) and trackpad (mouse does not move, however plugged-in USB mouse does) This sounds to me like a driver issue, however I cannot figure out how to re-enable my drivers, re-install them, or whatever I have to do here. This did not happen durring my upgrades from 12.04 to 12.10, or 12.10 to 13.04, so I'm at a total loss as to why this happened this time around. My computer is a Lenovo Z570, dual-booting Ubuntu and Windows 7 from GRUB 2. Windows is working fine as far as I can tell.

• Android design advice - services & broadcast receivers

  - by basudz

  I'm in the process of learning the Android SDK and creating some projects to get a grasp on the system. The current project I'm working with works just fine but I'd like to get some advice about other ways I can go about designing it. Here's what it needs to do. When a text message is received from a specific number, it should fire off a toast message that repeats at a certain interval for a specific duration. To make this work, I created an SMS BroadcastReceiver and checked the incoming messages for the number I'm looking for. If found, an IntentService would be started that would pull out the interval and duration from saved shared prefs. The IntentService would then fire off a broadcast. The BroadcastReceiver for this would catch it and use the AlarmManager to handle the toast message repetitions. This all works just fine, but I'm wondering if there's a cleaner or more efficient way of going about doing this? Any suggestions or advice?

• EVGA GTX650Ti Boost / Ubuntu 12.04 / 2 X-Star WQHD

  - by user210045

  I bought 2 X-Star WQHD monitors which, predictably, did not work with my on board video card. Yesterday I installed the EVGA card and have been trying to get the NVIDIA drivers to work. I tried to install the 304 .run, I tried to remove that and then install the nvidia-current, then I tried to activate the proprietary driver from within Ubuntu...for the first couple of attempts, I was able to see 800x600 or something close on the X-Star displays but now all I see is flashing colors on those. On my older Samsung monitor (S22B300B 21.5") is still displaying through the EVGA card. Any thoughts on how to go about fixing this?

• Why are the proposed BADSIG (on apt-get update) fixes secure?

  - by EvanED

  I'm running apt-get update, and I see errors like W: GPG error: http://us.archive.ubuntu.com precise Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <[email protected]> It's not hard to find instructions on how to fix these problems, for instance by asking for the new keys with apt-key adv --recv-keys or rebuilding the cache; so I'm not asking about how to fix these. But why is this the right thing to do? Why is "oh, I need new keys? Cool, go get new keys" not just defeating the purpose of having a signed repository in the first place? Are the keys signed by a master key that apt-key checks? Should we be doing some additional validation to ensure that we're getting legitimate keys?

• Which app can I use for easily annotating pictures/screenshots?

  - by koushik

  Often I need to annotate (draw some arrows, lines, basic shapes like squares, ellipses etc and enter some text) on top of pictures (JPG, PNG images) and screenshots (again png images). I would also need to be able to crop, resize etc. I tried the Gimp but I could only enter text and perform all image transformations but couldn't find a way to draw boxes etc. I finally settled to Openoffice.org draw, but I know that isn't what I want, because in oodraw I need to insert my pic into a drawing and resize it (or the drawing) to fit and then go about making changes and finally export to png... Is there any image editor that allows adding shapes and text to jpg & png files and save the modified file in its place? If the tool can also have template collections (like dia does) for shapes that is an added bonus.

• What is an achievable way of setting content budgets (e.g. polygon count) for level content in a 3D title?

  - by MrCranky

  In answering this question for swquinn, the answer raised a more pertinent question that I'd like to hear answers to. I'll post our own strategy (promise I won't accept it as the answer), but I'd like to hear others. Specifically: how do you go about setting a sensible budget for your content team. Usually one of the very first questions asked in a development is: what's our polygon budget? Of course, these days it's rare that vertex/poly count alone is the limiting factor, instead shader complexity, fill-rate, lighting complexity, all come into play. What the content team want are some hard numbers / limits to work to such that they have a reasonable expectation that their content, once it actually gets into the engine, will not be too heavy. Given that 'it depends' isn't a particularly useful answer, I'd like to hear a strategy that allows me to give them workable limits without being a) misleading, or b) wrong.
