• CSS and HTML incoherences when declaring multiple classes

  - by Cesco

  I'm learning CSS "seriously" for the first time, but I found the way you deal with multiple CSS classes in CSS and HTML quite incoherent. For example I learned that if I want to declare multiple CSS classes with a common style applied to them, I have to write: .style1, .style2, .style3 { color: red; } Then, if I have to declare an HTML tag that has multiple classes applied to it, I have to write: <div class="style1 style2 style3"></div> And I'm asking why? From my personal point of view it would be more coherent if both could be declared by using a comma to separate each class, or if both could be declared using a space; after all IMHO we're still talking about multiple classes, in both CSS and HTML. I think that it would make more sense if I could write this to declare a div with multiple classes applied: <div class="style1, style2, style3"></div> Am I'm missing something important? Could you explain me if there's a valid reason behind these two different syntaxes?

• Count a row VS Save the Row count after each update

  - by SAFAD

  I want to know whether saving row count in a table is better than counting it each time of the proccess. Quick Example : A visitor goes to Group Clan, the page displays clan information and Members who have joined the group,Should the page look for all the users who joined the clan and count them, or just display the number of members already saved in table ? I think the first one is not possible to get manipulated with but IT MIGHT cost performance Your Ideas ?

• Web to Print system - which client side technology should I use

  - by mr null

  I'm getting started to develop Web to Print system. My main concern is which client-side techology should I use: jQuery/CSS Flex/ActionScript or something else? For now, idea is that user/customer choose Product eg: Business card Attributes: Dimensions,Paper type, ... etc Template or blank Adjust product (editor) Preview & order Output should be PDF 300dpi. My main issue is: adding/adjusting text in editor. (font size, font family...). Because application should be cross browser. And I think that 10px Arial can't be the same in Firefox 5 and IE 8. It must be pixel perfect in every browser. If somebody order $100 of business cards, and text is different that he/she saw when ordering - that is a big problem. So, Flash platform should be the answer. But, as I see it's dying technology, 2012 is here - HTML5 is replacing Flash rapidly. I hope that you understand me, so every guideline or few smart words would be very appreciating.

• Freelancers do you have a surcharge for going to client site to work?

  - by user35072

  I'm currently new to freelancing as a programmer and need to work what some of the "norms" are without making myself look like an amateur. I've already won some work from a local company doing C# development and quoting an hourly rate for work that i am doing from my office. However on one upcoming project I've been asked to come on-site (client office) to work a full week. Is it reasonable to charge more than my regular hourly rate for working on site? And how should i justify the extra charges?

• A good substitute for ASMX web service methods, but not a general handler

  - by Saeed Neamati

  The best thing I like about ASP.NET MVC, is that you can directly call a server method (called action), from the client. This is so convenient, and so straightforward, that I really like to implement such a model in ASP.NET WebForms too. However, in ASP.NET WebForms, to call a server method from the client, you should either use Page Methods, or Web Services, both of which use SOAP as their communication protocol (though JSON can also be used). There is also another substitution, which is using Generic Handlers. The problem with them however is that, a separate Generic Handler should be written for each server method. In other words, each Generic Handler works like a simple method. Is there anyway else to imitate MVC model in ASP.NET WebForms? Please note that I can't change to MVC platform right now, cause the project at our hand is a big project and we don't have required resources and time to change our platform. What we seek, is a simple MVC model implementation for our AJAX calls. A problem that we have with Web Services, is the known problem of SoapException, and we're not interested in creating custom SoapExctensions.

• Django as Python extension?

  - by NoobDev4iPhone

  I come from php community and just started learning Python. I have to create server-side scripts that manipulate databases, files, and send emails. Some of it I found hard to do in python, comparing to php, like sending emails and querying databases. Where in php you have functions like mysql_query(), or email(), in python you have to write whole bunch of code. Recently I found Django, and my question is: is it a good framework for network-oriented scripts, instead of using it as a web-framework?

• Why are PHP function signatures so inconsistent?

  - by Shamim Hafiz

  I was going through some PHP functions and I could not help notice the following: <?php function foo(&$var) { } foo($a); // $a is "created" and assigned to null $b = array(); foo($b['b']); var_dump(array_key_exists('b', $b)); // bool(true) $c = new StdClass; foo($c->d); var_dump(property_exists($c, 'd')); // bool(true) ?> Notice the array_key_exists() and property_exists() function. In the first one, the property name(key for an array) is the first parameter while in the second one it is the second parameter. By intuition, one would expect them to have similar signature. This can lead to confusion and the development time may be wasted by making corrections of this type. Shouldn't PHP, or any language for that matter, consider making the signatures of related functions consistent?

• Is it reasonable to expect knowing the whole stack bottom up?

  - by Vaibhav Garg

  I am an Sr. developer/architect/Product Manager for embedded systems. The systems that I have had experience with have typically been small to medium size codebases - typically close to 25-30K LOC in C, using 8-16 and 32 bit low end microcontrollers. The systems have been entirely bootstrapped by our team - meaning right from the start-up code to the end application code has either been written by the team, or at the very least, is thoroughly understood and maintained by us. Now, if we were to start developing more complex systems with complex peripherals, such as USB OTG et al. (think, low end cell phones), there are libraries and stacks available commercially and from chip vendors that reduce the task to just calling the right APIs and being able to use those peripherals. Now, from a habit point of view, this does not give me and the team a comfortable feeling, not being able to comprehend the entire code tree, with virtual black boxes at the lower layers. Is it reasonable to devote, and reserve, time getting into the details of how the APIs are implemented, assuming that the same would also entail getting into details of relevant standards (again, for USB as an example)? Or, alternatively, should a thorough understanding of the top level usage of the APIs be sufficient? This of course assumes that the source codes to all libraries are available, which they are, in almost all cases. Edit: In partial response to @Abhi Beckert, the documentation is refreshingly very comprehensive and meticulously maintained, AFAIK and been able to judge. I have not had a long experience with the same.

• C++ program...overshoots? [migrated]

  - by Zdrok

  I'm decent at C++, but I may have missed some nuance that applies here. Or maybe I completely missed a giant concept, I have no idea. My program was instantly crashing ("blah.exe is not responding") about 1/5 times it was run (other times it ran completely fine) and I tracked the problem down to a constructor for a world class that was called once in the beginning of the main function. Here is the code (in the constructor) that causes the problem: int ii; for(ii=0;ii<=255;ii++) { cout<<"ent "<<ii<<endl; entity_list[ii]=NULL; } for(ii=0;ii<=255;ii++) { cout<<"sec "<<ii<<endl; sector_list[ii]=NULL; } entity_list[0] = new Entity(0,0); entity_list[0]->_world = this; Specifically the second for loop. The cout references are new for the sake of telling where it is having trouble. It would print the entire "ent 1" to "ent 255" and then "sec 1" to "sec 255" and then crash right after, as if it was going for a 257th run through of the second for loop. I set the second for loop to go until "ii<=254" which stopped all crashes. Does C++ code tend to "overshoot" for loops or something? What is causing it to crash at this specific loop seemingly at random? By the way, entity_list and sector_list point to classes called Entity and Sector, respectively, but they are not constructing anything so I didn't think it would be relevant. I also have a forward declaration for the Entity class in a header for this, but since none were being constructed I didn't think it was relevant either. EDIT: It was due to the new Entity line, I assumed wrongly that the fact that altering the for statement to 254 fixed the crashes meant that it had to be there. I still don't understand why the for loop is related, though.

• Pause and Resume and get the value of a countdown timer by savedInstanceState [closed]

  - by Catherine grace Balauro

  I have developed a countdown timer and I am not sure how to pause and resume the timer as the TextView for the timer is being clicked. Click to start then click again to pause and to resume, click again the timer's text view. This is my code: Timer = (TextView)this.findViewById(R.id.time); //TIMER Timer.setOnClickListener(TimerClickListener); counter = new MyCount(600000, 1000); }//end of create private OnClickListener TimerClickListener = new OnClickListener() { public void onClick(View v) { updateTimeTask(); } private void updateTimeTask() { if (decision==0){ counter.start(); decision=1;} else if(decision==2){ counter.onResume1(); decision=1; } else{ counter.onPause1(); decision=2; }//end if }; }; class MyCount extends CountDownTimer { public MyCount(long millisInFuture, long countDownInterval) { super(millisInFuture, countDownInterval); }//MyCount public void onResume1(){ onResume(); } public void onPause1() { onPause();} public void onFinish() { Timer.setText("00:00"); p1++; if (p1<=4){ TextView PScore = (TextView) findViewById(R.id.pscore); PScore.setText(p1 + ""); }//end if }//finish public void onTick(long millisUntilFinished) { Integer milisec = new Integer(new Double(millisUntilFinished).intValue()); Integer cd_secs = milisec / 1000; Integer minutes = (cd_secs % 3600) / 60; Integer seconds = (cd_secs % 3600) % 60; Timer.setText(String.format("%02d", minutes) + ":" + String.format("%02d", seconds)); //long timeLeft = millisUntilFinished / 1000; }//on tick }//class MyCount protected void onResume() { super.onResume(); //handler.removeCallbacks(updateTimeTask); //handler.postDelayed(updateTimeTask, 1000); }//onResume @Override protected void onPause() { super.onPause(); //do stuff }//onPause I am only beginner in android programming and I don't know how to get the value of the countdown timer using savedInstanceState. How do I do this?

• Wecam not detected

  - by Richard

  after much research ang googling, my web cam is still not recognized. In the time of Ubuntu 11.04 it was working fine. I did a fresh install of 11.10 and not more web cam. All the cheese and camera monotor and V4L tests and all failes with "cannot connect to /dev/video0" or equivalent. The output of 'lsusb' shows the webcam Bus 001 Device 002: ID 05a9:2640 OmniVision Technologies, Inc. OV2640 Webcam What I noticed is that neither /dev/v4l nor /dev/video* exists. If I re-install the v4l package all the /dev/video* are created, but no /dev/v4l If I reboot the /dev/video* are NOT created. I think the trouble is that the device are not created at boot time. I have a DELL Inspiron 1525 and until this fresh install the web cam worked fine. Can somebody help ? Thanks a lot Richard

• One click access to bookmarked files?

  - by dunderhead

  On my Windows machine with just one click I can launch favourite or bookmarked files that I use on a daily basis, which is a great time-saver. Is there any way to do this with 11.10 Unity? Ideally I would like to right-click on an icon in the launcher and have a list of files appear that I could then left-click to launch, but I'd be happy for any simple solution. Please note that I am not referring to recently used files lists - these do not work at all because the bookmarked file will always drop off the bottom of any recently used file list.

• Is there a quick way to enter uppercase accented characters?

  - by agnul

  I know I can enter any character I need using the character-map applet, but that means grabbing the mouse/opening the "run" dialog, switching to another window, selecting the character, copying... you get the idea. Is there a quicker way to enter characters that are not available on the keyboard (and are not available as alt-gr combinations)? In my specific case I'm using a laptop with the Italian keyboard layout, but I suspect a general solution exists.

• How to change tooltip background color in Unity?

  - by kayahr

  In a lot of applications the tooltips are just plain ugly (White text on black background, way too much contrast) or even unreadable (black or dark blue text (Hyperlinks) on black background). I want to change the background color of the tooltips to some medium gray or even some yellow or something like that, maybe even something semi-transparent. Here is a screenshot of Eclipse which displays some source code in a tool tip with black text on black background: Switching to a different theme (Something other than Ambiance or Radiance) helps but I like Ambiance and I want to keep it. It's just this darn tooltip color which is absolutely unacceptable. I found several solutions for older Ubuntu versions but they no longer work with Unity in Ubuntu 11.10 because I can't find any function to customize the Ambiance or Radiance theme. So how do I do that in the current Ubuntu version?

• ROOT_MISMATCH error after following FAQ directions

  - by Adko

  While using Ubuntu One in 11.04 I am unable to change my account info. When I made the switch to 11.04 I forgot that I already had an Ubuntu One account so, I made a new one. However, upon going through one of my email accounts I found my old Ubuntu One login information. I then attempted to switch the account associated with my desktop to my first email. Now, despite following the directions found at https://wiki.ubuntu.com/UbuntuOne/FAQ/WhatToDoWhenSyncdaemonSaysRootMismatch I continue to get the error "File sync error. (local and server roots are different (ROOT_MISMATCH))". Any help would be appreciated.

• Broadcom 4313 Signal strength very low on an HP Pavilion dv4

  - by thegreyspot

  I have a HP pavilion dv4 4141US laptop running fresh ubuntu 11.10. This laptop has a broadcom 4313gn chipset for the network card. The network card is using the brcmsmac driver. Which, I heard else where on askUbuntu that its the best driver to be using for this card. I can connect to my network, however I have extremely low network signal. Right now I am right in front of the router, and I only get 72%. If i go to the room directly behind the router's wall, i get no signal, where as with windows 7 I get a nice 70% percent. UPDATE: I use WEP at home and an open wireless connection at work. Both have same result. Both are completely different routers. Also you G What can i do?

• Diagnosing xmodmap errors

  - by intuited

  I'm getting this error when trying to use xmodmap to get rid of caps lock: $ xmodmap -e 'clear Lock' X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 118 (X_SetModifierMapping) Value in failed request: 0x17 Serial number of failed request: 8 Current serial number in output stream: 8 I'm running xfce on Maverick "10.10" Meercat. This problem did not occur before I added the Keyboard Layouts applet to a panel; before doing that, I was able to run my xmodmap script to swap Esc and CapsLock: !Remap Caps_Lock as Escape remove Lock = Caps_Lock keysym Caps_Lock = Escape It may be relevant that I chose alt-capslock as the keyboard switch combo in the Keyboard Layouts preferences. I've had a similar problem before, on a different machine, running openbox. On that machine, this problem started when I upgraded to Lucid, and has persisted in Maverick (release 10.10). I reported a bug in xorg. However, it remains unclear whether it's really a problem with xorg, or if I'm just doing something wrong with my configuration. Have other people experienced this problem? Can someone shed some light on what's going on here? It seems there are quite a few layers involved, and I don't understand any of them particularly well, so any information would be helpful. update I've discovered that the problem is specifically triggered by adding the Canada layout variant "Multilingual" (ca-multix). If I instead add the variant "Multilingual (first part)", the problem does not occur. I think this will probably end up being a usable workaround, but I don't yet know what the difference between these variants is. I've filed a freedesktop issue, and am commenting on a related ubuntu issue.

• The new Google Analytics - what new useful features have you found?

  - by Rob

  If you don't know already a new version of Google Analytics has just come out. On first initial views it doesn't seem like much of an improvement on the previous version. There's lot's linking to Google's social stats but I'm yet to see the value of that. Also it doesn't seem to make the best use of the important data, it's tending to push referral sites, keywords to the back and bring the less important data to the front. Is that a sign of things to come??? One feature I did find interesting was the visitors flow as it shows the visitors path through your site. What new features have you found useful/interesting?

• Why is Google not indexing my forum?

  - by jsoldi

  I have this web site that as you can see on the top right has is a "Forums" button that links to my forums. My problem is that if, for instance, I make a Google search "site:heliumscraper.com answers" I don't get any result, even though the word "answers" is in the forum's board index and it has been there for a few months already. I don't have a robots file. I also uploaded a sitemap to Google that contained the forum. I'm thinking the problem might be the fact that the only link from my main page to the forum opens in a new window. Could this be the problem?

• Are copyright notices really required?

  - by Alasdair

  Ever since I made my first web page 13 years ago I have followed the pattern of showing a copyright notice in the footer of each page. Over the years the format of this notice has changed in the following way; Copyright © <NAME> yyyy. All rights are reserved. Copyright © <NAME> yyyy © yyyy <NAME> © <NAME> This has generally mirrored the format used by Google. However, I recently noticed that they no longer display a copyright notice on their home page nor have one in their source code/meta tags. I see they still display it on most (if not all) other pages. I understand that Google are very keen to keep the word count down on their homepage, which could be the reason for this sacrafice, but my question is more general and relates to all websites. Since I've always just done it out of habit, I'm hoping someone can explain if/when I a copyright notice is actually required to protect your content and rights. Also, when it is required, is there a format in which the notice must adhere to in order to be valid?

• trouble setting up dns for vps

  - by Zenph

  I had registered a domain at namecheap and forwarded the dns to my host at vps.net. The strange thing is, when I did that the site was showing up. I even uploaded files and everything was displaying correctly on my new domain. Now, it is just the namecheap holding page again. I have no idea why this is happening as I haven't touched the configuration since it was working. Could anyone point me in the right direction? When I enter http://domain.com it redirects to http://www.domain.com and the namecheap holding page is shown. Prior to this domain.com was showing what the host was serving. I am completely lost and have no idea where to start so I'd appreciate any help I can get.
