• How to track opens and pageviews in PDFs?

  - by Osvaldo

  I know how to track clicks in links to pdfs and pfd's downloads. But I need to track how many times a PDF is opened after being downloaded and if possible track how many times certain pages are shown to users. Tracking has to be done without warnings that personal information is being sent somewhere. I do not want readers personal informations, just to know how many opens happened, so this warnings would be inaccurate. Can anyone help by pointing to a tutorial or an example? If you are sure that this can't be done, can you please point to documentation that explains why?

• Should I implement an interface directly or have the superclass do it?

  - by c_maker

  Is there a difference between public class A extends AbstractB implements C {...} versus... public class A extends AbstractB {...} AbstractB implements C {...} I understand that in both cases, class A will end up conforming to the interface. In the second case, AbstractB can provide implementation for interface methods in C. Is that the only difference? If I do NOT want to provide an implementation for any of the interface methods in AbstractB, which style should I be using? Does using one or the other have some hidden 'documentation' purpose?

• My boss decided to add a "person to blame" field to every bug report. How can I convince him that it's a bad idea?

  - by MK_Dev

  In one of the latest "WTF" moves, my boss decided that adding a "Person To Blame" field to our bug tracking template will increase accountability (although we already have a way of tying bugs to features/stories). My arguments that this will decrease morale, increase finger-pointing and would not account for missing/misunderstood features reported as bug have gone unheard. What are some other strong arguments against this practice that I can use? Is there any writing on this topic that I can share with the team and the boss? I find this sort of culture unacceptable to work in but want to try and change it before jumping ship. Any input is appreciated.

• Frameworks for targetting multiple environments

  - by Werlang

  What should drive the decision behind doing development upon one or more than one framework? For instance, an ERP is (mostly) run on a Windows station. It leverages full access to device's resources, like printers, barcode readers, fingerprint readers and the like. It's usually more responsive and easier do develop with. That being said, some parts of it must be accessed exclusively in self-service mode, by enterprise's customers, suppliers and partners. This could be accomplished with smartphones, tablets, or even desktops running a web browser. What are the economics behind that? Should two team be kept, each one doing work upon its own framework? Or the most permissive framework should be chosen? Should I care something other than HTML technologies? Should I consider native technology for each device?

• Dynamic Post-build event in Visual Studio

  - by SSumner

  I am building a video server application that has multiple projects in Visual Studio. One project, the video server project, needs to call a shell script to generate documentation. This works fine when you build the video server project, because the script is simply cd "$(SolutionDir)" start documentationgenerator However, there is also an SDK project that, when built, also builds the video server project. However, when it does this, it does not know where the shell script is, since it tries to use the SDK Project's Solution Directory. SDK Project Video Server Project shell script So the question is: how do I make the SDK Project find the Video Server Project? I checked the MSBuild properties and there are no properties that seem to deal with 'nested' projects.

• Ubuntu 10.10 screen goes nuts and unreadable

  - by ChazD

  Running Ubuntu 10.10 in its own partition, also have Oracle Virtualbox 4 with Windows XP. Because i previously had a problem with a dark screen when i let the laptop on and i didn't use it for a long while i had set Power settings to Never sleep, never let the Display sleep. Monitor on install set to Laptop resolution 1400 by 1050, refresh rate 60 Hz, rotation Normal. The problem was when the computer was left on and i returned after about an hour, the screen was unreadable, similar to what used to happen to graphics cards before multisync became normal. So it appears as though the graphics card was asked to use a resolution it couldn't handle and went nuts. I had to power off the system, on restart everything was fine. Thanks for any suggestions.

• Programming vs Planning

  - by MattW

  Recently I have been tasked with more High level planning assignments due to the lead developer of my team leaving. I hate long term planning. My brain just doesn't naturally seem wired for it and I am not interested enough in it to spend the time to learn it (it is hard enough to keep up with the programming side of the picture). Can I still be a good programmer without being a high level planer too? Are you expected to be good at planning out the entire product and picking a date, as part of being a senior programmer. Is it possible to be a good programmer and not a high level planner?

• Scrum in a consulting environment?

  - by Darla

  Is it possible to introduce scrum to a consulting environment? On any given week I might belong to 4 different teams, each with a different PM, BA and dev team (I am a designer). It doesn't seem feasible, time wise, to be able to be part of that many teams/projects as there would need to be daily stand-ups for each, sprint reviews, etc. I should add these projects are not necessarily software, but mainly ecommerce web projects. Can someone who has done this speak to how you approach it?

• Can I use my VirtualBox 3.* VMs with VirtualBox 4.0? If so, how come the repository doesn't have it?

  - by ximbim

  I had the following repository for virtualbox in my /etc/apt/sources.list: deb ttp://download.virtualbox.org/virtualbox/debian maverick non-free Then I found out there was a new version when I opened it today (the program prompted me with a window to manually download it from Oracle's site). Then I tried sudo apt-get update && sudo apt-get upgrade and got nothing. Here you have a way to add virtualbox-4.0 to your apt-get, but the problem is that it isn't updating, meaning I would have the two installed. I'm also worried if I'll have to do something like that each time it updates since that would defeat the point of apt-get. I've been using virtualbox with the apt-get update for more than a year now and this is the first time it has happened, so I was wondering if there would be a way to just update my current installation.

• 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.

• Getting through a lengthy book?

  - by Mr_Spock

  This may seen like a weird question, but since we're challenged--as engineers--to constantly adapt to changing technologies, we always find ourselves buried in documentation. That said, we also need to consider that time is of the essence because people want their stuff fixed and improved with little hesitation if any. How do you get through lengthy manuals, books/manuals within a short period of time? Take for example: "The Linux Programming Interface," by Michael Kerrisk, which is roughly 1500 pages in length. How would you get through a monster of a book like this if you're pressed for time while still learning most of the material?

• Can Agile/Scrum be used by 1 or 2 developers?

  - by Dillie-O

  Everything I've been reading and researching up to this point describes how Agile/Scrum works great with teams of about 4 to 6 members, maybe even more. In my current shop, we have about 8 developers or so, but given the nature of the volume of projects and the number of departments we support, we never have more than 1 or 2 folks assigned to a given project. Can I still use Agile/Scrum with a team of 1 or 2 developers? I'm working on making the pitch to my manager to start working with this methodology, but I need to be able to explain how to scale things back for a small developer crew, or convince them to make sure we get more members on a given project.

• Is this ask ubuntu, or am i in twilight zone? [closed]

  - by user66987

  I had a question to canonical, but that got closed. Is this ask ubuntu? Sure doesn't seem like it. I had a valid question, but since it contained critisism of one of the ubuntu teams, it got closed down. All I am after is a 100% translated ubuntu into my language. But my local team do not work, so this will not happen. So much for an open community. Well, I will think real hard next time I can help someone, and I will probably not. Since I can't get any help. I have one question, and this is directed at someone in charge of ask ubuntu. Why does a valdid question get locked down? My closed question Yeah, this is such a good comunity. Don't expect any help from me in the future.

• What type of application is this called?

  - by boatingcow

  I am working on a web-based application which combines elements of what my client would call a CMS (content management system) and CRM (customer relations management) but also adds in many other business-specific features such as bookings management, staff task allocation management, wages calculations, document version control etc. However, I'm struggling to find a catch-all term for this type of application so I can research how other people have gone about creating such an integrated solution. Can anyone recommend a term I can use to refer to this, both internally in our team, for the client so they know what to call the 'system' and also for me personally, so that I can ask the Stack community further questions?

• How to convince the agile product owner to change their mind? [closed]

  - by Joshiatto

  A friend of a friend ran into a situation recently in which the agile product owner specified features down to exactly what every single user click should look like. The problem is, the dev team has already figured out a way to accomplish the business value in fewer clicks (better UX), but in the past, questioning the product owner has led to career disaster. How do we convince the product owner to change their mind and go along with our recommendation? What can be done within the agile model to fix this situation and how do we accomplish it? On a bigger level: What can be done to make agile product owners better at their job to prevent this kind of thing from happening?

• Hiring developers - listing IDE as a requirement?

  - by suslik

  I've been looking at some job postings and noticed that a fair amount of them list IDEs under the 'required skills' section, even for senior positions. This is not localized to one company either, but rather it's something that comes up once in every few postings. I am perplexed by this job requirement, as my mentors and some of the best coders I've seen in my life were VIM/Emacs ninjas. Similarly, when I work with people I don't much care what tools they use as long as they are productive on the team. Can someone please explain the rationale behind hiring managers making IDEs an official job requirement?

• is requiring a video player download acceptable

  - by wantTheBest

  Our site currently is going to require our users to download a player to view videos they will want to view on our site. The videos get uploaded by users from various sources (smartphones in 3gp format for example). However most people have Flash on their machines. I am trying to 'make a gentle stand' and tell the team that requiring a download of a video player is not acceptable. My thinking is this: instead of allowing people to upload 3gp and other formats then re-serving the exact format on REQUESTs from our site's users we will instead use a video converter such as FFMpeg to convert every uploaded video to FLV for viewing on flash. so when a user requests to view one of the videos on our site -- boom they probably already have Flash installed so we just play the video in their Flash player. I feel serving up FLV flash video is best. Does it ring true that requiring, say, a 3gp player download just to view a video is the wrong approach?

• How to enable a Web portal-based enterprise platform on different domains and hosts without customization [on hold]

  - by S.Jalali

  At Coscend, a cloud and communications software product company, we have built a Web portal-based collaboration platform that we like to host on five different Windows- and Linux-based servers in different hosting environments that run Web servers. Each of these Windows and Linux servers has a different host name and domain name (and IP address). Our team would appreciate your guidance on: (1) Is there a way to implement this Web portal-based platform on these Linux and Windows servers without customizing the host name, domain name and IP address for each individual instance? (2) Is there a way to create some variables using JavaScript for host name and domain name and call them from the different implementations? If a reference to the host/domain names occurs on hundreds of our pages, the variables or objects would replace that. (3) This is part of making these JavaScript modules portable and re-usable for different environments and instances. The portal is written in JavaScript that is embedded in HTML5 and padded with CSS3. Other technologies include Flash, Flex, PostgreSQL and MySQL.
