• Computer Science graduate. Master or full-time job? [closed]

  - by Alex

  Possible Duplicate: Is a Master's worth it? I have just gotten my Bachelor's Degree in Computer Science and I have to make choice. Whether to continue with my full-time job I just got or put the job slightly in the background and concentrate on getting a Master's degree. I am currently working as an embedded C developer in a small company. The cool thing is that, because the team is quite small, my engineering ideas really play a part in the final product. Not to mention that I get to work on very different areas of embedded programming: device drivers and development of a Real Time OS. I am very enthusiastic about my job and what I do. On the other hand, in my country there isn't really a master's degree that focuses on embedded development so my gain from getting this degree will mainly in the field of general computer science knowledge. That being said, is it worth giving up all my spare time which I now use to study different areas of embedded devices and work mainly to get a degree rather than pure knowledge and experience in the field I want to work in?

• How to Use Vim-Style Keyboard Shortcuts for OS X Tab Navigation

  - by The Geek

  After switching to OS X when I got a new MacBook Air, one of the first things I needed to duplicate was my extremely customized AutoHotkey setup — the most important of which is using the J and K keys to navigate throughout tabbed windows easily. Yeah, I’m a Vim user. I’ve never been a fan of having to use CTRL + TAB to switch from one tab to the next — to start with, you have to move your hands from the home row, and it’s awkward, and why should I have to do that just because somebody decided that keyboard shortcut before tabs became popular? If you think about it, if tabbed browsers were popular back when keyboard shortcuts were being invented, they would have definitely reserved some of the good shortcuts for switching tabs. On Windows, I’ve always used an AutoHotkey script to make things the way I wanted it:  ALT + J and ALT + K for selecting previous and next tabs. Once you get used to it, it’s extremely awesome, and so much faster than using CTRL + TAB. Of course, I also hacked CTRL + T and CTRL + W into ALT + T and ALT + W so I could open new tabs and close them without moving my hands from the home row. Over on OS X, it turns out that it’s incredibly simple and easy to use CMD + J and CMD + K for next/previous tab navigation, and it works in most applications that support tabs, like Terminal, Safari, or Google Chrome.

• Developer with 4 years experience with Java/C++. How to move into web programming? [closed]

  - by JerryC

  Possible Duplicate: Tips for switching jobs and moving into web based programming? I graduated in 2006 with a computer science degree and got solid grades (3.5 overall 3.8 in my major) For the past 4.5 years I've been working as a Software Engineer doing primarily rich client development. Most of my experience is with Java, Swing and C++. I've done a lot of network programming and I have acquired some skill working & debugging in distributed environments. I would like to switch jobs and move into a role where I can get exposure to some new technologies and frameworks. I would like to move into a more web development role but I find my lack of web development experience is hurting me. 90% of the jobs I see advertised are looking for one of two skill sets: 1) Stereotypical server side Java web developer. Experience with Spring, Hibernate, J2EE, etc. 2) Stereotypical front end web developer. Experience with Javascript, jQuery, HTML5, GWT, CSS, etc I find most of these companies are looking really specifically for this experience and they are not willing to take on good programmers/ CS fundamental guys who lack experience with this stuff. I would love to get a job doing stuff like this, but have my skills become out of date and unmarketable? Any opinions on ways to sell myself to help get a new position?

• Duplicated menu, panel indicators and taskbar

  - by Mykro

  Ubuntu 12.04. The first time I log into Gnome Classic I get a duplicate of every menu, panel indicator and taskbar entry. If I log out and back in again I now have three copies. Log out and log in, four copies and so forth. What would cause this? I can't see any obvious duplicates in the process list: $ ps -A | grep 'gno\|org\|nau' 27439 tty7 00:00:18 Xorg 27610 ? 00:00:00 gnome-keyring-d 27621 ? 00:00:00 gnome-session 27674 ? 00:00:00 gnome-settings- 27709 ? 00:00:07 gnome-panel 27720 ? 00:00:00 gnome-fallback- 27726 ? 00:00:04 nautilus 27736 ? 00:00:00 polkit-gnome-au 28281 ? 00:00:00 gnome-screensav 29016 ? 00:00:00 gnome-terminal 29021 ? 00:00:00 gnome-pty-helpe If it helps, I was recently trying the Nouveau drivers but have now reverted to NVIDIA. Configuration is Separate X Window, Xinerama enabled. Unity is fine, so the problem is limited to the Classic desktop. I haven't had any luck googling these particular symptoms so any tips would be really appreciated. Thanks!

• Is there a way how to customize my keyboard layout in Xubuntu in a graphical way (by clicking)?

  - by Honza Javorek

  Possible duplicate, but I really couldn't find a solution. I would like to adjust my US keyboard layout, e.g. to add possibility to type some special characters on combination of right Alt + another character, etc. Moreover, my arrow up is dead, so until I buy another keyboard, I'd like to use my right shift as my arrow up, ASAP. However, there seems to be no way how to edit my keyboard layout easily in Xubuntu :( I found no editor and I really don't want to spend years in some configuration files and terminal (not that I can't, but I really really don't want). KLE - the only editor I could find, but no installation guide, no package, no PPA, no idea how to make it working (and uninstallable if not needed one day) Editor in Ubuntu - apparently not present in Xubuntu I found several tutorials how to change the layout, but they all seems to be complicated and not easy to follow. I don't want to spend a weekend in terminal or so, I am looking for an app to launch, make some clicking, finish my work by hitting Save button and - done! Please, is there such solution? For humans?

• Dual displays not working with Xinerama in Ubuntu 12.04

  - by user68489

  I just upgraded from Ubuntu 10.10 to 12.04. I had been using a display configuration just like the one described at http://bitkickers.blogspot.com/2009/08/rotate-just-one-monitor-with.html without any problems under 10.10. I have an nvidia Quadro FX 380 and have upgraded to the latest drivers (295.49). Everything appears to be fine when the system first boots up. However, after logging in, the left screen goes black, and the right screen displays what should be displayed on the left screen. Logging into Ubuntu 2D somewhat improves things. The left screen correctly displays the left portion of the desktop but the right screen contains a duplicate view of the left screen. Turning off Xinerama and enabling TwinView appears to fix the issues but does not allow the right monitor to be rotated. Since the display problems start to occur only after logging on, I thought it might have to do with carryover user configuration from 10.10 but the problems persist even when logging in as a guest. Clicking on System Settings - Displays results in the error message "Could not get screen information - RANDR extension is not present." Any help would be greatly appreciated.

• Ubuntu live cd : black screen and blinking cursor

  - by IFasel

  I try to install ubuntu 12.04 on my computer. I can get to the purple screen on the live cd but then, if I choose "Installing Ubuntu", I have a black screen with a cursor blinking (and nothing else happens). My PC : acer aspire M3920, CPU i5-2300, 8 Gb RAM, NVIDIA gt 405. What I already tried : I tried with 12.04 and 13.04 daily build I tried with a live usb and with a live dvd I tried the following boot options : nomodset, acpi=off I googled a lot and it seems that it could be a graphic card problem. Do you know any other boot options that I could try ? UPDATE This is not a duplicate : I've tried all the common boot options (nomodeset, noacpi...) and it doesn't change anything. With the option "no splash" (instead of "quiet splash"), I can see what happens before the forever-blinking cursor : [sdg] no caching mode present [sdg] assuming drive cache : write trough ata8.00: excetion Emask 0x52 ... frozen ata8 : SError : { RecovData RecovComm UnrecovData...} ata8.00 : failed command : IDENTIFY PACKET DEVICE ... ata8.00 : status : { DRDY } ata8 : hard resetting link Does somebody know what it means ? N.B. astonishingly, Puppy Linux boots fine (but Debian, Fedora and Ubuntu do not) Solution In fact, it was not a graphic card problem. I had to disconnect the dvd drive and connect it to another free sata connector (I don't really understand why Ubuntu had trouble with this connector and Windows 7 not). After that, everything worked fine.

• What is a good way to refactor a large, terribly written code base by myself? [closed]

  - by AgentKC

  Possible Duplicate: Techniques to re-factor garbage and maintain sanity? I have a fairly large PHP code base that I have been writing for the past 3 years. The problem is, I wrote this code when I was a terrible programmer and now it's tens of thousands of lines of conditionals and random MySQL queries everywhere. As you can imagine, there are a ton of bugs and they are extremely hard to find and fix. So I would like a good method to refactor this code so that it is much more manageable. The source code is quite bad; I did not even use classes or functions when I originally wrote it. At this point, I am considering rewriting the whole thing. I am the only developer and my time is pretty limited. I would like to get this done as quickly as possible, so I can get back to writing new features. Since rewriting the code would take a long time, I am looking for some methods that I can use to clean up the code as quickly as possible without leaving more bad architecture that will come back to haunt me later. So this is the basic question: What is a good way for a single developer to take a fairly large code base that has no architecture and refactor it into something with reasonable architecture that is not a nightmare to maintain and expand?

• How to build a good service layer in ASP.NET?

  - by Swippen

  I have looked through some questions, technologies for building a good service layer but I have some questions regarding this that I need help with. First some information of what I have for requirements. We currently have a number of web applications that talk to each other in a spiderweb looking way (all talking to each other in a confusing way via webservices and database data). We want to change this so that all applications go through a service layer where we can work more with cache and encapsulate common functionality and more. We want this layer to also have a Web API so that 3rd party clients can consume information from the service. The problem I see is that if we build the service layer with say MVC4 Web API don't we need to communicate between the application using the webAPI meaning we have to construct URLs and consume JSON/Xml. That does not sound too effective. I assume a better method would be working with entities and WCF to communicate between the application but then we might loose the Web API magic? So the question is if there is a way to consume a service layer as both a Web API (JSON/XML) and as a more backend service layer with entities. If we are forced to use 2 different service layers we might have to duplicate some functionality and other bad things. Hope the question is clear enough and please ask if you need any more information.

• Do ALL your variables need to be declared private? [closed]

  - by skizeey

  Possible Duplicate: Why do we need private variables? I know that it's best practice to stay safe, and that we should always prevent others from directly accessing a class' properties. I hear this all the time from university professors, and I also see this all the time in a lot of source code released on the App Hub. In fact, professors say that they will actually take marks off for every variable that gets declared public. Now, this leaves me always declaring variables as private. No matter what. Even if each of these variables were to have both a getter and a setter. But here's the problem: it's tedious work. I tend to quickly lose interest in a project every time I need to have a variable in a class that could have simply been declared public instead of private with a getter and a setter. So my question is, do I really need to declare all my variables private? Or could I declare some variables public whenever they require both a getter and a setter?

• Will we be penalized for having multiple external links to the same site?

  - by merk

  There seem to be conflicting answers on this question. The most relevant ones seem to be at least a year or two old, so I thought it would be worth re-asking this question. My gut says it's ok, because there are plenty of sites out there that do this already. Every major retailer site usually has links to the manufacturer of whatever item they are selling. go to www.newegg.com and they have hundreds of links to the same site since they sell multiple items from the same brand. Our site allows people to list a specific genre of items for sale (not porn - i'm just keeping it generic since I'm not trying to advertise) and on each item listing page, we have a link back to their website if they want. Our SEO guy is saying this is really bad and google is going to treat us as a link farm. My gut says when we have to start limiting user useful features to our site to boost our ranking, then something is wrong. Or start jumping through hoops by trying to hide text using javascript etc Some clients are only selling 1 to a handful of items, while a couple of our bigger clients have hundreds of items listed so will have hundreds of pages that link back to their site. I should also mention, there will be a handful of pages with the bigger clients where it may appear they have duplicate pages, because they will be selling 2 or 3 of the same item, and the only difference in the content of the page might just be a stock #. The majority of the pages though will have unique content. So - will we be penalized in some way for having anywhere from a handful to a few hundred pages that all point to the same link? If we are penalized, what's the suggested way to handle this? We still want to give users the option to go to the clients site, and we would still like to give a link back to the clients site to help their own SE rankings.

• Is text-only mode a saving or a problem for battery savings?

  - by Robottinosino

  A friend is flying to the US from Europe and asked me a very thought-provoking question, which I am not remotely able to answer with substance so I am asking it here: How to absolutely maximise battery life on an Ubuntu (laptop) install? do not rush to mark this as duplicate, there is an important point here: does -GNOME- help or worsen battery life? Let me provide some context: The only task he needs to perform is: edit text files in Vim. He is unsure whether running GNOME will drain his battery life more or actually save him some battery life given the smarts of GNOME's power management features like "switch this peripheral to -power save- after X minutes..." (GNOME might just be a configuration front-end for settings that are governed by command-line utils for all I know?) He could perfectly well boot the system in text-only mode and use the automatic 6 virtual consoles for his needs, if that's a saving at all over running tmux (I think so because of all the smart buffering/history/etc the latter does by default?) Exactly how would you advise him to run his laptop during his flight? What I told him already: power off WiFi in the BIOS, not from the "GUI" power off Bluetooth switch off the courtesy light and use low monitor brightness play music off of his phone, not mp3blaster do not use his tiny portable mouse (and do not attach any other USB gimmicks like "screen light", etc) stop development services he will not be using, especially apache2, tomcat, dovecot, postgresql, etc. Potentially: - switch off his cron jobs? (he does an rsync + tar + 7za of his "work in progress" every so often) I think the above is standard stuff one could get off StackExchange, and with many duplicates... the core of this question is, I think: __ will running Ubuntu in text-only mode be a saving in terms of battery life or a problem? why? (provide some technical arguments) __ I think it will be a saving but I am also scared about "other things" detecting and enabling advanced chipset power management features only when some services are started.. and fear these "services" may be off in text-only mode?

• Grub can not boot after resizing windows XP (NTFS) partition. What is to be done? [closed]

  - by cipricus

  Possible Duplicate: How to Repair Grub while dual booting ( win7 / ubuntu 11.10) I had installed Lubuntu on a PC with Windows XP and used dual boot for some time with no problems. Since I had almost abandoned Windows (kept it for printing...) I decided to resize its ntfs partition and add the free space to my Ubuntu space. Tried that with a gparted stick and a live cd but would not work due to an issue related to the ntfs partition: gparted signaled with a red exclamation point that there was a problem with that partition. I read that a checkdisk might solve it but in the end used EaseUS in Windows to shrink (resize) the ntfs partition and create a new one (ext3) from the space left. All seemed ok with that procedure: but resizing the partition and moving the data might have affected the grub file: or whatever the following message means, which I get when trying to start my pc: error: file not found grub rescue> Booting from a live cd I see, beside the shrinked windows partition and my old linux one, the newly created partition, containing a directory called lost+found that I cannot open.

• Form development optimization

  - by Juan

  Like many web developers I do forms all the time. I found myself doing the same all the time: placing input fields, assigning a name to each, ajax the form, then create the PHP which involves to assign a PHP var to each $_REQUEST['var'], escape and validate data, build the html and emailing the results. So I found that 70% of the work is duplicated but I just can't duplicate a page and change the fields. I end up wasting more time reformatting, deleting and adding different fields than creating from scratch. I started planing to program a "list of IDs to html+php" converter in which I'd input all the IDs and this would output the basic html and php. Then I thought: there's got to be thousands of developers that go through this, I'd be reinventing the wheel. So this is my question, I'm trying to find that wheel that somebody must have invented already. I found this: http://www.trirand.com/blog/jqform/ which does more or less what I'm looking for but it's an expensive solution and it has too much functionality for what I'd be using it. Which tools do you use to optimize repetitive task about HTML and PHP?

• How to encourage domain experts familiar only with C into a C++ opensource project [closed]

  - by paperjam

  Possible Duplicate: How to persuade C fanatics to work on my C++ open source project? I am launching an open-source project into a space where a lot of development is done Linux-kernel-style, i.e. C-language with a low-level mindset. My project is broad and complex and uses aspects of the C++ language and libraries, including the Boost library to best effect for simple, slightly syntactically sweetened, elegant and well structured high level code. We are using C++ templates too to avoid duplication of code and for static polymorphism in code specialisation for performance. Many of the experts in this field are well used to pure C-language projects. How can I persuade them to contribute to my idiomatic C++ based project? I have no objection to C-language subcomponents or the use of a C-like subset for parts of the project so that might be part of the answer. This is a rewritten and retagged rehash of my previous question that was closed. Apologies to those who read and answered for it not being constructive. I hope this new question is viewed as constructive. Please note that this is not a language advocacy question and please keep answers in that spirit.

• Spend Analytics on a Grand Scale

  - by jacqueline.coolidge(at)oracle.com

  The Wall St. Journal reports in Billions in Bloat Uncovered in Beltway that a recent study by Government Accountability Office (GAO) has released a massive study of several programs and agencies that cost U.S. taxpayers billions of dollars each year.  This report help save $100 to $200 Billion dollars by identifying duplicate spending and ineffective programs that can be consolidated or eliminated. Now, that is spend analytics on a massive scale! It remains to be seen how actionable that information will be.  Certainly, there have been studies before that identify wasteful spending.  But, it’s a great case of the power of business intelligence and spend analytics.   Many companies do find significant savings when they implement spend and procurement analytics. What makes for an excellent spend analysis? It should be: Objective and provide visibility across programs and/or divisions A cross functional analysis that links financial with performance metrics Prescriptive and actionable Spend and procurement analytics have been HOT during the economic downturn! I expect 2011 will see many more companies get serious about spend analytics and would love to hear from companies who are willing to share their experience.

• Google Indexing Issue after htaccess changes

  - by Klement

  I have a site called www.FuneralCoverFinder.co.za. I have about 30 pages on the site and usually have 29 indexed. (Excluding 15 blog posts) They are new. I recently upgraded my entire site and made some redirection changes in my .htaccess file. I have made my url's more SEO friendly (Removing index.php/) and redirecting dead pages to working pages. I have tons of unique content all checked by grammarly and plagium to ensure I have no duplicate content. I have since resubmited my sitemap to Google and now have only one page indexed. It was within a couple of minutes. I usually see results almost immediately after submitting, now it's stuck on 1 page indexed. I assume I might have made errors in the .htaccess file as this was my first attempt. The site runs perfectly and all the url's redirect the way they should. I'm scared I have some or other loop, although the website runs fine. I still see many of my old indexed pages in the SERP's, I'm just worried that the issue with the new sitemap can cause my rankings some harm. My website is pretty SEO optimized onsite. I have about 1500 indexed backlinks and have been building them steadily over about half a year. I would really appreciate some clarity on this matter.

• How to maintain a demo version of an application?

  - by O.O

  I need to be able to demo our production application to prospective clients. The way I have it setup today is simple. The demo application is an exact duplicate of the production system, except that the data in the database is obfuscated to protect our current clients' data. This works great because it doesn't require any application changes. Boss dropped a potential BOMBSHELL today and said that the demo system needs to contain a special link and that ONLY shows up on demo. He went on to explain that in the future there may be much bigger differences between the demo and production apps (e.g. an entire area of functionality). What do I do now? Some things I have thought about doing: Maintain a different branch in subversion specific to the demo system Create an installation package that has the changes for demo, then revert and build a production installation package Modularize the application (no idea how) Say: "Screw you! I will not do it!" (LOL) Use some sort of conditional logic in the app to determine if it is a demo or a production app. E.g. (if the URL contains 'demo' then show else hide). If you haven't guessed by now, this is a web application Anyways, I have no experience in this scenario as to which one is better or if none of these are any good.

• Should I be concerned that I can't program very fast without Google? [closed]

  - by seth

  Possible Duplicate: Google is good or bad for programmer? I'm currently in college to be a software engineer, and one of the main principles taught to us is how to learn for ourselves, and how to search the web when we have a doubt. This leads to a proactive attitude - when I need something, I go get it. Recently, I started wondering how much development would I be able to do without internet access and the answer bugged me quite a bit. I know the concept of the languages and how to use them, but I was amazed by how "slow" things were without having the Google to help in the development. Most of the problems I have are related to specific syntax. For example, reading and writing to a file in Java. I have done this about a dozen times in my life, yet every time I need to do it, I end up googling "read file java" and refreshing my memory. I completely understand the code and fully understand what it does, but I am sure that without Google it would take me a few tries to get the code correct. Is this normal? Should I be worried and try to change something in my programming behaviour?

• With Google DFP (Small Business) is it possible to disable AdSense in an Ad Slot on a per-request basis?

  - by Daniel Pehrson

  Setup: I run a network of websites that target different hobby niches and have a section dedicated to community classifieds. I serve advertising on these sites through Google DFP for Small Business with AdSense enabled on the slots. Problem: One of the next sites in my network will be targeting the firearms/shooting industry and as such the classifieds section will not comply with the prohibited content guidelines of AdSense regarding the sale (or coordination of sale) of weapons. I work very hard to comply with the guidelines of my partners even if I don't understand/agree with them and after talking with many people have decided that the best option is to disable AdSense serving on that section of that website, while leaving it on for the rest of the network. Solution: Right now my only idea for this is to duplicate all my site's ad slots and tack a "_sensitive" onto the end of each one (eg. header and header_sensitive) conditionally registering ad slots based on whether or not I am in the sensitive section of the sensitive site. My hope however is that there may be a way to accomplish this without duplicating all my ad slots possibly with some sort of options to the GA_googleFillSlot() call that allows me to say "load ads from this slot but do not serve AdSense no matter what."
