• Printing Off Center or Images Offset After Upgrade to 14.04 LTS (Brother HL-2240)

  - by fortitude

  :) I have a very frustrating problem with my Brother HL-2240 under Ubuntu 14.04. Bear in mind this was working perfectly under Ubuntu 13.10. In Firefox, when I print a webpage, all of the images are off center and cut off, this is a big deal for my work. In Google Chrome, when I print a webpage, the page is off center, toward the right margin. In Opera, when I print a webpage, all of the white areas within the margins are black, using a lot of toner. PDF opened in document viewer, prints off center. Steps I have taken to troubleshoot: 1) Playing with the printer settings, resetting to defaults, etc. 2) Un-installing the Brother driver and re-installing (linux-brprinter-installer-2.0.0-1 from the Brother website), which works perfectly in Ubuntu 13.10. I see a similar, un-answered question, here. Hopefully this question provides some additional clarity to the matter. If anyone would like some additional detail because she or he is willing to help, please let me know. I can scan output from the printer to show you. Thank you.

• Issue with increasing the root partition from the swap

  - by user211761

  I have an issue with increase the size of my root partition. I have ElementaryOS Luna, and while installing it asked me how much space I want to use. I choosed 15 GB for it, because I want to use this as an alternative system. The issue is that after the installation was complete, I found out that my root partition is only 7 GB big, and SWAP is 8 GB which is useless cuz I have 8 GB of RAM. Now I want to shrink the swap and increase the size of my root partition, so I booted the LiveCD and used GParted. I shrinked the swap without any problems, but now I cant add that free space to any partition. I also turned Swap off. I would add a picture, but I need at least 10 reputation to post images ( Stupid ) Its also worth mentioning that in Gparted its showing my partition in a different way. I would post an image BUT I CANT, so I need to write it down. Its something like this [Pointing arrow down] /dev/sda4 Extended /dev/sda5 ntfs /dev/sda6 ext4 (Which is my main partition) /dev/sda7 linux-swap unallocated Picture:

• Is there any kind of established architecture for browser based MMO games?

  - by black_puppydog

  I am beginning the development of a broser based game in which players take certain actions at any point in time. Big parts of gameplay will be happening in real life and just have to be entered into the system. I believe a good kind of comparison might be a platform for managing fantasy football, although I have virtually no experience playing that, so please correct me if I am mistaken here. The point is that some events happen in the program (i.e. on the server, out of reach for the players) like pulling new results from some datasource, starting of a new round by a game master and such. Other events happen in real life (two players closing a deal on the transfer of some team member or whatnot - again: have never played fantasy football) and have to be entered into the system. The first part is pretty easy since the game masters will be "staff" and thus can be trusted to a certain degree to not mess with the system. But the second part bothers me quite a lot, especially since the actions may involve multiple steps and interactions with different players, like registering a deal with the system that then has to be approved by the other party or denied and passed on to a game master to decide. I would of course like to separate the game logic as far as possible from the presentation and basic form validation but am unsure how to do this in a clean fashion. Of course I could (and will) put some effort into making my own architectural decisions and prototype different ideas. But I am bound to make some stupid mistakes at some point, so I would like to avoid some of that by getting a little "book smart" beforehand. So the question is: Is there any kind of architectural works that I can read up on? Papers, blogs, maybe design documents or even source code? Writing this down this seems more like a business application with business rules, workflows and such... Any good entry points for that?

• Why would he say "We don't want to support MVC3"?

  - by MadBurn

  I work in a small shop at a fairly big company doing intranet web applications. By small, I mean there is 1 other guy in my position... and he graduated with me last December. (we aren't the only IT, but the only ones in our field) We are switching out an old COBOL system and converting it's only used application suite to a Web App. My company has contracted to a Web Application firm to help with this process who has chosen ASP.NET MVC, during one of the important meetings I asked if they will be using MVC2 or MVC3. Their lead developer said: "MVC2, we don't want to support MVC3. haha" My question is, why is this? This was several months ago and I've been doing extensive and self training gearing up for the MVC switch. From everything I am understanding, MVC3 is just like MVC2 if you don't use Razor and it fixes a number of smaller bugs that MVC2 had. So in my eyes, I can't see any reason to NOT use MCV3. There has to be something I'm missing. Since I don't really have any mentors to turn to in the real world, I'm coming here. What problems are there with MVC3 that might possibly lead him to say this that I'm missing?

• Should I sell video tutorials on my own or via publishers like lynda.com? [closed]

  - by Derfder

  I am asking this because I am deciding between two models right now. One way is to create video tutorials on my own (make some short free videos and long pay per download/stream videos) or sell them to lynda.com or tutsplus. The 2nd way is easier, because they will do all the boring business stuff, will host the files to download etc. In that case, everything I need is a good microphone and obey their guidelines. On the other side if I do it on my own, I have to do all the unwanted business stuff, pay the server and other stuff. This is quite a big downside, however, I will have all the videos under my control in the future. I know that lynda.com has bigger attention and marketing that I am capable, but if you take e.g. phpvideotutrials.com (r.i.p ;), I think Leigh was very successful with relatively small budget. The interesting question will be the cost or how much will they pay me. Would it be less than if I sell it myself+monthly server hosting+other expenses? Any advice from people who actively sell their videos to some companies or do it on they own is highly appreciated.

• Is Version control with GIT useful to work in small projects fon an individual developer? [closed]

  - by chefnelone

  I work as website developer. I develop with Drupal CSM. I have a drupal base installation which has some settings which are sort of default for all my proyects. This drupal installation is my drupal-base folder Every time I start a new project I just duplicate the `drupal-base- folder and start coding the new features I need for the new proyect. The problem is that sometimes I work in more than one projects at the same time and I get a new feature in one of the project that I'd like to commit to my drupal base installation and also to the other projects. Then keeping the sync of all this is nightmare. I thought that Version Control with GIT could help me with this and I went into a tutorial about it. But now I'm not sure if this will be usefull for me. Then my question is: I think that GIT is just usefull for big projects where a team is working all together in the same files. But it is not usefull to work in small and individual projects. Am I right?

• Creating Ideal Customers with Modern Marketing

  - by Richard Lefebvre

  “Without that real-time perspective, it's just not possible to stay in step with what your customers want and need.” — Customer-Obsessed Marketing Is Your Next Competitive Edge Every business talks about focusing on the customer. But few actually deliver. Why? Because digital marketing technology can’t tell a compelling story. It lacks engaging dialogue with no connection beyond the transaction. It’s lost in translation because marketers don’t speak code. And it’s confusing to the customer because marketing and IT can’t connect process and data. Take a look at your digital marketing picture. From a distance it may look fine. But look up close. It’s fragmented and the dots are not connected. You need much higher resolution. Step back and see the big picture. Zoom in on the individual customer. But you’ll need Modern Marketing technology engineered with enterprise grade data management and proven cloud performance. Explore the people, processes, and technology of the Oracle Marketing Cloud. Create a culture of customer obsession.

• Life Is Full Of Changes (Part 1)

  - by Brian Jackett

  Today will be my last day with Sogeti.  I’ve been with Sogeti USA for just over 4 years.  In that time I’ve gotten to work on some great projects, develop relationships with some brilliant and passionate people, participate in the .Net developer and SharePoint communities, and grow my skills in a number of areas I’m passionate about.     As with all good things they must come to an end though.  I’ve accepted a position with another company and will provide more details once the transition has completed.  This decision was a difficult one to make but it provides a great career opportunity on many levels.  As much as my new schedule allows I plan to continue participating in local user groups, speaking at conferences, and blogging.     Speaking of which, you may have noticed my reduced blogging activity in the past few months.  In addition to a career change I’m also in the process of moving to a new residence (only a few miles from my current residence, so I’ll still be in Columbus.)  Searching for a new place, filling out paperwork, and all of the other work associated with this move has taken away a good chunk of the time I used to devote to blogging.  Once everything gets settled out with the move and job change I’ll re-evaluate how much time I can devote to blogging.     A big thanks to Sogeti and everyone who has been so supportive over my time with them.  It’s hard to move on, but I am excited for the prospects that the future will bring.         -Frog Out

• Working with volonteers

  - by JavaCecilia

  I've been engaged as a scout leader in the Scout movement since 1993, working on a local and national level, leading both kids and other scout leaders.Last year, the Swedish Scout Association invited 40000 scouts aged 14-17 years old from 150 countries around the world to go camping for 10 days. I was on the planning team with a couple of hundreds of my closest scout friends and during a couple of years we spent our spare time planning logistics, food, program, etc to give these youths an experience of a life time. It was a big and complex project; different languages, religion (Ramadan was celebrated during the camp) and the Swedish weather were some of the factors we had to take into account. The camp was a huge success, the daily wow factor was measured and people truly had fun and got to know each other. I learnt a lot and got friends around the globe - looking back at the pictures it feels unreal that we managed it.The Java platform as OpenJDK and its' future is a similar project in my mind. With 9 million developers and being installed on 3 bn devices, the platform touches a lot of users and businesses. There's a strong community taking Java into the future, making sure it stays relevant. Finding ways to collaborate in a scalable way is the key to success here. We have the bylaws directing how decisions are made, roles are appointed and how to "level" within the community. Using these, we can then make contributions according to our competence and interest and innovate taking our platform into the future.If you find a way to organize volunteers towards a common goal, solving conflicts, making decisions, dividing the work into manageable chunks and having fun while doing it - there's no end to what you can achieve.

• What should a programmer's yearly routine be to maximize their technical skills?

  - by sguptaet

  2 years ago I made a big career change into programming. I learned various technologies on my own without any prior experience. I really love it and feel lucky with all the resources around us to help us learn. Books, courses, open-source, etc. There are so many avenues. I'm wondering what a good routine would be to follow to maximize my software development skills. I don't believe just building software is the way, because that leaves no time for learning new concepts or technologies. I'm looking for an answer like this: Take a new concept sabbatical/workshop 2 weeks per year. Read 1 theoretical and 1 practical programming book per year. Learn 1 additional language every 2 years. Take a 1 week vacation every 6 months. Etc. I realize that the above might sound naive and unrealistic as there are so many factors. But I'd like to know the "recipe" that you think is best that will serve as a guide for people.

• Developing an Interface to a Dynamic System

  - by radix07

  I work for a small company and have been designing a GUI to interface our embedded system. The problem with this embedded system is that it is not a finished product (may never be) and is constantly under development and being tweaked and updated for different customers and applications in small volumes. So to deal with this I made a program that can export all the data from a spreadsheet where most of the embedded system variables are sourced from and throw them into a small database for the GUI application to use. This database program I made also spits out a cross reference file for the embedded system which allows the GUI to look up all the variables. This system works pretty well so far, and is even integrated with version control among the GUI, database, and embedded system. The big problem is that there is constant development on several projects that use this system and it gets terribly tedious to keep the system up to date and bring in new changes. This has gotten to the point to where I have had to code the GUI to dynamically (generically) generate all interfaces since I am never guaranteed to find the same data the same way. I have not been able to come up with a good way to uniquely identify the data I import from excel since all fields are able to be changed (due to engineering stubbornness, code re-factoring and/or excel issues) and I cannot assign a fixed reference within the sheet itself. So, are there any good methods or ideas on how to handle the chaos?

• Find methods related to testcases in Java

  - by user3623718

  I want to automatically change some methods in the program. These methods contain some compiler error and my program aims to fix these compiler errors. After fixing compiler errors I need to run test cases related to the changed method (or class) to know it is correct and if not which test cases failed. As the programs under investigation are very big, I only need to run test cases related to changes. As an example, if I change one method, then I need to only run test cases related to this method. Therefore, what I need is to programmatically be able to find test cases related to each method, and class. It is also useful if there is a tool that can do that for me. As an example, a tool which creates a matrix shows each test case is related to which method(s) One easy way to do that is to run all test cases and save functions they accessed. However, the problem is at the beginning the input program contains compiler error and it is not possible to run test cases because of these compiler error. Please let me know what is the best way to do that. An API or a tool that I can be used programmatically is the best for me.

• What is the average page size for single page application (SPA)? [on hold]

  - by Emmanuel Istace

  I'm developing a single page application with a lot of css & javascript. For now the page is 1.3Mo composed by 5 section. Here are the rounded stats : Document : 10kb Style : 60kb Images : 450 kb (already compressed, include a big gallery thumbnails) Javascript : 700kb - 600kb of "framework" (jquery, jquery-ui, boostrap, modernizer, waypoint, ...) and 100kb of custom js. Fonts : 125kb And the site is not finished yet. (Will include gmap api, and some others...) My questions are : Do you have any statistics about the average weight of an SPA? As this is the whole website, do you think it's acceptable? Is lazy load (for images) a solution? What will be impact for SEO ? Is the "200kb rule" of google still relevant? Do you know great tools to detect which javascript code is not used during the the exection of a page and then the availability to optimize these 700kb of framework js stuffs? Can a caching strategy be an answer?

• Windows Recovery from Grub messed up my computer?

  - by Hudson Worden

  Ok so I'm a noob when it comes to Operating Systems and I think I really messed up this time. So I have a laptop that dual boots Windows 7 and Linux Mint 11. I was trying to boot into Windows 7 but it would just have a black screen with a blinking cursor. So I turned off my computer and tried again. Still a black screen with a cursor. So I thought "well it must be broken somehow and I remembered seeing something like 'Windows Recovery' from the boot menu so I should try it." So when I turned on my computer a third time I selected 'Windows Recovery' (Something like that I can't remember exactly what it was called). After I had selected that I got a white Windows window that said in big red letters "ERROR". I turned off my computer again a turned it back on expecting the Grub menu to reappear. I was wrong. Instead I am greeted with error: no such partition grub rescue. Then I put in a live CD for ubuntu 11.04 and tried looking at my partitions using the disk manager. Looking at my partitions I notice that there isn't a Linux partition anymore and in its place is a unallocated space partition yet the Linux Swap partition is still there. My windows partition is still fine and I can access the files in it. If you understand what has happened, is there anyway I can get my files back? I don't care about reinstalling the OS again. I just want those files that are in the Linux Mint partition.

• Printer Canon MP540 succesfully added finally but doesn't print? (Attached Debug log)

  - by NES

  i tried to setup my printer in Ubuntu 10.10. I had to use special guide to install because Canon used libcupsys2 in its packages and ubuntu expects libscupsys i followed this guide in reference to this advice. The first problem was this one (the ubuntu "add printer dialog asked for root credentials". The suggested workarout in Launchpad to create a root password worked. Now i added the printer. It's available for printing. Then i got an error message "cups insecure filter" which prevented me from printing. That could be solved by setting the need root rights in the /usr/lib/cups/filter/ directory. The error message disappeared after restarting cups service. Now it should work but it doesn't. The main problem is now, the printer seems to be proper setup but when i try to print a document, the printer icon appears for short time in gnomepanel. There's a printing job in Queue which got completed, but the printer doesn't print. I attached the Debuglog provided by printer error control, had to upload to another site, since it was to big in the question body here. Perhaps someone can identify the problem with it? Note: i know that it once worked fine with an older release of Ubuntu, but not sure which version this was.

• Dropping the full-time high-pay gig - I need help choosing a smart path that I can rely on to produce enough to survive comfortably ($2,500 per month)

  - by Jeff V

  I have about 6 years of full time experience developing web applications and tools. I know perl, python, PHP, ruby, and a good deal of SQL and relational theory. I have never had to choose a self-employed path as I have always had full time work or a bank account (credit cards) to support a big project. I'm planning to move out of the country to an area that will not offer local employment, and need some advice on what to focus on. I want to move in no more than six months, I have enough savings to live for an additional six months, but I would like to conserve it as much as possible. I enjoy taking risks, so I'm not looking for discussion of whether this is a good idea or not. I want advice on the most reliable solution given my skill set. Some paths I'm considering: Learn objective-c and build quality Apple software. Develop subscription based web tools for SEO, or other Marketing applications Attempt to acquire freelance projects by developing a reputation within open source projects, freelancer.com, and other online communities The last time I left my job, I was building a startup (that went under), and missed out living in a beautiful place due to the amount of time I worked. I would like to work 30-40 hours per week max. I can dedicate 10-15 hours per week while at my current job to prepare and learn. A preemptive thanks for the advice...

• Data Access Objects old fashioned? [on hold]

  - by Bono

  A couple of weeks ago I delivered some work for a university project. After a code review with some teachers I got some snarky remarks about the fact that I was (still) using Data Access Objects. The teacher in question who said this mentions the use of DAO's in his classes and always says something along the lines of "Back then we always used DAO's". He's a big fan of Object Relational Mapping, which I also think is a great tool. When I was talking about this with some of my fellow students, they also mentioned that they prefer the use of ORM, which I can understand. It did make me wonder though, is using DAO's really so old fashioned? I know that at my work DAO's are still being used, but this is due to the fact that some of the code is rather old and therefor can't be coupled with ORM. We also do use ORM at my work. Trying to find some more information on Google or Stack Exchange sites didn't really enlighten me. Should I step away from the use of DAO's and only start implementing ORM? I just feel that ORM's can be a bit overkill for some simple projects. I'd love to hear your opinions (or facts) about this.

• SEO questions about PR, Page Structure, and Other

  - by jasondavis

  A couple of basic questions related to SEO. 1) If I have a site that has several different niches that I am trying to promote from. Example Web Developer broke down into section of Web Design, Graphic Design, Programming, Software for SEO purposes, would it be better to use subdomains for these main sections or use the main domain with a folder like structure? 2) Is PR different for each page of a domain or ever page has a PR of the same on that domain? Also do sub-domains have a different PR? 3) When entering a hugely over saturated niche such as web-design, is it even possible to compete with the big sites that have been ranked on google #1 page for years? 4) Lastly, I have read about how important titles, link anchors, and headings are for SEO and how content is the most important. So left's say we are building a standard header, body, sidebar, footer page. In the the actual markup, would it be better to make sure the main content comes before the sidebar on the page or does this probably not make a difference? 5) I seen mentioned in another answer here that microformats can help with SEO, is there any fact behind this? Thank you for any info on this

• We really only have ONE rule...

  - by Chris G. Williams

  Had to show someone the door today... bummer.     At Big Robot Games we really only have one rule and it's not all that complex:   If you're going to hang out here all day, you should satisfy AT LEAST one of the following criteria: 1) You buy some food and/or drinks. 2) You occasionally buy product. 3) You play as part of a sanctioned tournaent or gaming group. 4) You act like you have some sense (i.e. have manners.)   We would love it if you manage to do all of the above, of course, but we're really perfectly content to settle for only getting a 1-2 of them at a time.    We don't have a problem with people bringing food in, and we understand that you aren't going to buy a game every time you come here. And yes, we know that people enjoy hanging out here with their friends. We can even overlook your odd quirks and personality issues, provided you're spending a little money once in a while (this IS a BUSINESS, after all.)   However... if you can't manage to do ANY of the things I listed above, and then you get lippy with me about it, well... it's time to say goodbye.

• Browser Statistics for Geekswithblogs.net

  - by Jeff Julian

  I love Google Analytics!  It helps me so much during my day-to-day maintenance of Geekswithblogs.net and our other sites.  I can see so much data about our visitors and come up with new ways of delivering more content to our readers so they can really get the most out of our community.  Browsers and Browser Versions is a big indicator for me to help decide what we can support and what we need to be testing with.  The clear browsers of choice right now are Chrome, IE, and Firefox taking up 94.1%.  The next browser is Safari at 2.71%.  What this really brings to my attention besides I better test well with Chrome, Firefox, and IE is that we are definitely missing an opportunity with Mobile devices.  We really need to kick up the heat when it comes to a mobile presence with Geekswithblogs.net as a community and the blogs that are on this site.  We need easy discovery of new content and easy tracking of what I like.  I am definitely on mission to make this happen and it will be a phased approach, but I want to see these numbers changes since most of us have 2 or 3 mobile devices we use for Social activities, but tools are lacking for interacting with technical data besides RSS readers.

• How to modify partitions after install?

  - by ChocoDeveloper

  I wanted to have Ubuntu with full disk encryption on one big partition, and Windows on a small one. In 12.04, only the Server Edition installer has full disk encryption, so I used that and then installed ubuntu-desktop. When it asked for the size, I reduced it from ~999GB to ~750gb. Now after the install, on both gparted and disk utility I see /dev/sda2 taking ~931GB, and nothing unallocated, so I can't create a partition for windows. I got the size right, because when I right-click inside a folder, then hit 'properties', I see Free space: ~690GB (I don't know why it's not ~750GB, but at least it's not 900). The command df -h shows the same. So what can I do? Normally I would just resize a partition with gparted to create unallocated space, then create the partition. But here I have two problems: gparted does not seem to be showing the correct values, and also it says it does not support LUKS so I'm afraid it will mess things up. Any thoughts?

• How can I get better at explaining complex software processes to developers?

  - by Lostsoul

  I'm really struggling with my software specs. I am not a professional programmer but enjoy doing it for fun and made some software that I want to sell later but I'm not happy with the code quality. So I wanted to hire a real developer to rewrite my software in a more professional way so it will be maintainable by other developers in the future. I read and found some sample specs and made my own by applying their structure to my document and wanted to get my developer friend to read it and give me advice. After an hour and a half he understood exactly what I was trying to do and how I did it(my algorithms,stack,etc.). How can I get better at explaining things to developers? I add many details and explanations for everything(including working code) but I'm unsure the best way I can learn to pass detailed domain knowledge(my software applies big data, machine learning, graph theory to finance). My end goal is to get them to understand as much as possible from the document and then ask anything they do not understand, but right now it seems they need to extract alot of information from me. How can I get better at communicating domain knowledge to developers?

• My first blog post…

  - by steveh99999

  I’ve been meaning to start a blog for a while now, (OK, for several years…..) - finally now, here it begins First post, something really simple but, a wise-man once told me about the best way to improve SQL server performance. Store Less Data. That's it.. that's all there is to it... Over the years, I've seen the following :- -  a 200Gb database which held 3 days data. Once business requirements changed, we were able to hold only 1 days data in this database. -  a table developed by DBAs to hold application table cardinality information - that information was collected at 2 hour intervals every day for 7 years ! After 7 years the DBA space-info table had become the largest table in the database - 60 million rows !  It was a simple change to remove alot of the historical intra-day data and change the schedule to run only once per evening. Suddenly that table held 6 million rows instead of 60 million.... - lots of backup and restore history held in msdb. See this post by Brent Ozar for more details on this issue. Imagine how much faster the backups, DBCC Checks and reindexes ran when the above 3 changes were implemented ?   How often do you review your big databases \ tables to see if you’re actually holding only data that is really required by the business ?
