• How Is there anyway to Compile Notepad++?

  - by user44179

  I really like using Notepad++ to write HTML and such. After I started using Ubuntu I looked around for an alternative to Notpad++. I found a thread which lead me to try Geany and a few others, but I really miss Notepad++. Is there anyway I could compile it from the source code to use on Ubuntu? I know its written in C++. Could I just open it in Code::Blocks and compile it? You can get the source here. I wouldn't mind hearing about other alternatives, but really want to know if compiling it is possible. Thanks

• Disabling IPv6 on a single interface

  - by ijw

  I'm slightly weirded out by the fact that Ubuntu won't process ipv4 DHCP unless you explicitly tell it to, but will happily take ipv6 RAs unless you tell it not to. Is there any way to change the default behaviour to be 'do nothing unless I explicitly turn it on'? (Note to answerers: I'm not looking to globally disable ipv6, or completely turn off autoconf. I'm looking to disable autoconf by default (as in, I don't want ipv6 unless I say so in /etc/network/interfaces, in the same way that I don't just get a v4 address unless I've explicitly turned on dhcp). What's happening is that, for any interface that's up - e.g. has an ipv4 config - a v6 address tends to just turn up on the interface as well, despite the fact that I've not enabled that explicitly. The solutions to date are fine as far as they go, but if I disable v6 or autoconf globally, I can't then re-enable v6 on a per-interface basis with a simple command in /etc/network/interfaces. I'm fairly sure I'm asking for the moon on a stick, mind you.)

• How best to merge/sort/page through tons of JSON arrays?

  - by Joshiatto

  Here's the scenario: Say you have millions of JSON documents stored as text files. Each JSON document is an array of "activity" objects, each of which contain a "created_datetime" attribute. What is the best way to merge/sort/filter/page through these activities via a web UI? For example, say we want to take a few thousand of the documents, merge them into a gigantic array, sort the array by the "created_datetime" attribute descending and then page through it 10 activities at a time. Also keep in mind that roughly 25% of these JSON documents are updated every day, and updates have to make it into the view within 5 minutes. My first thought is to parse all of the documents into an RDBMS table and then it would just be a simple query such as "select top 10 name, created_datetime from Activity where user_id=12345 order by created_datetime desc". Some have suggested I use NoSQL techniques such as hadoop or map/reduce instead. How exactly would this work? For more background, see: Why is NoSQL better for this scenario?

• Qualifying 'happiness' in software development?

  - by mummey

  It occurred to me today that often the real goal of questions asked on sites such as this one (where the questions tend to be more open-ended than say, SO) is for the OP to become happier upon achieving the result. We often excuse this by saying our desire is to be more productive or release a better product, but if you continue to look down this path you can determine that the OP seeks greater productivity or product-quality because those are important to his/her 'happiness'. With that in-mind I ask this: Have their been efforts to study software development from this perspective? In other words, what practises increase happiness in those who develop software as a career, and who, if anyone, has researched this specifically? As I mentioned above, they may include strategies that increase productivity or improve product quality, but by no means should they be limited to just those.

• Change guest username

  - by Eelviny

  Now, looking around on Google shows me some ways in which to customise the settings of the Guest session. But, I would love a way to change the name of the Guest account. Basically, I'm planning to take some laptops out to a school in Africa and want to rename the "Guest" account in 14.04 to "Student" so the students use that. They tend to store stuff on USB sticks and they're using the Guest account so they can't break anything. EDIT: I'll expand on this slightly. They're using the guest account simply for the reason it doesn't save anything after logoff. This was a specific thing the teachers have asked for. I don't mind if the actual username remains guest behind the scenes, but as long as it shows up as Student to on Unity. Any way of going about this?

• How to write efficient code despite heavy deadlines

  - by gladysbixly

  Hi all, I am working in an environment wherein we have many projects with strict deadlines on deliverables. We even talk directly to the clients so getting the jobs done and fast is a must. My issue is that i'd always write code for the first solution that comes to my mind, which of course I thought as best at that moment. It always ends up ugly though and i'd later realize that there are better ways to do it but can't afford to change due to time restrictions. Are there any tips by which I could make my code efficient yet deliver on time?

• Why do i keep forgetting things? [closed]

  - by Mr.Anubis

  I am currently learning many things at the same time in C++ and coded many data structures and algorithms and some small applications. When I suddenly try to remember something that I coded many months ago, my mind completely goes blank. It's like I'll have to re-learn the whole thing. For example, recently I was thinking to refactor my BST data structure, when I realized that I don't even remember how I coded it or how does it works internally. Does this happen with many others? Or is it me only? How do I overcome this problem?

• dedicated domain name VS just folders under a single domain?

  - by Ben Keating

  I run WordPress-Multisite for several sites. Each of these sites resolve under a single domain, e.g. example.com/foo/, example.com/bar/. I also have domain names for these e.g. foo.com, bar.com. which are currently redirects, so if a user hits foo.com, they are redirected (301) to example.com/foo/. My question is, should it be the other way around? should I use the dedicated domain names directly? What are the pros/cons of putting multiple sites under a single domain vs their own dedicated domains. I guess im asking with SEO and findability in mind.

• Working with vectors and transformations

  - by user29163

  I am going to write an graphical 2D application that allows user to create polygons and transform them through transformation such as rotation an so on. I was hoping someone can give pro and cons arguments for the different choices I got in my mind. (Its all in Java btw!) a). Represent vectors by filling matrices with 'real' numbers. This means making a matrix datas tructure that supports multiplication, transposing etc b). Make a own vector class, such that I can make a matrix class that support those vectors.

• What should I think about when switching from Python to Java?

  - by Nick Rosencrantz

  I was a Java developer in the early 2000s, switched to Python in 2008 and now Iäm working in Java again. Is there anything special you think I should keep in mind when going back to a Java environment? I used to work with EJB 1.0, I didn't work with EJB 2.0 and now we have JPA instead. I'm comfortable programming in Java and my new job with Java is much better than my Python job even though Python is my favorite language the tools and others things about my Java job makes it much better. I found when I searched jobs that demand for Java developer was much greater than demand for Python programmers- do you have a similar experience? Thank you

• Best language or tool for automating tedious manual tasks [closed]

  - by Jon Hopkins

  We all have tasks that come up from time to time that we think we'd be better off scripting or automating than doing manually. Obviously some tools or languages are better for this than others - no-one (in their right mind) is doing a one off job of cross referencing a bunch of text lists their PM has just given them in assembler for instance. What one tool or language would you recommend for the sort of general quick and dirty jobs you get asked to do where time (rather than elegance) is of the essence? Background: I'm a former programmer, now development manager PM, looking to learn a new language for fun. If I'm going to learn something for fun I'd like it to be useful and this sort of use case is the most likely to come up.

• Who makes laptops for Ubuntu?

  - by Tim Lytle

  I'm looking for a laptop and would like to avoid the whole 'is this [specific configuration of hardware] compatible with Ubuntu?' process by finding a laptop manufactured with Ubuntu in mind. I know of system76, but are there any other manufacturers making laptops built to run a standard build of Ubuntu? I'm not counting Dell, as - from my experience - their 'Ubuntu' laptops/netbooks require their build, and because of that have their own set of compatibility issues. UPDATE: And as mentioned in the comments, Dell is no longer selling systems with Ubuntu to consumers.

• When do you change your major/minor/patch version number?

  - by dave4351

  Do you change your major/minor/patch version numbers right before you release or right after? Example: You just released 1.0.0 to the world (huzzah!). But wait, don't celebrate too much. 1.1.0 is coming out in six weeks! So you fix a bug and do a new build. What's that build called? 1.1.0.0 or 1.0.0.xxxy (where xxxy is the build number of 1.0.0 incremented)? Keep in mind you may have 100 features and bugs to go into 1.1.0. So it might be good to call it 1.0.0.xxxy, because you're nowhere close to 1.1.0. But on the other hand, another dev may be working on 2.0.0, in which case your build might be better named 1.1.0.0 and his 2.0.0.0 instead of 1.0.0.xxxy and 1.0.0.xxxz, respectively.

• In the absense of a CS degree, how can I "fill in the gaps" so to speak?

  - by Richard DesLonde

  The problem here is that "I don't know what I don't know". How can I fill in those gaps? What is it that a computer science degreed person will know that I don't? Note: This isn't a personal question. I'm not asking you to read my mind so you can tell me where my knowledge is lacking. I'm really asking "Where/how can I get the knowledge a computer science degree would give me, without getting one?" Example: I don't know anything about compilers, but I understand that comp sci majors often are required to write some sort of compiler. This seems like something that would be useful to know. Etc.

• Ubuntu 13.04 is showing some error while opening my computer

  - by Singh

  Few months before when I was using Ubuntu 12.04 then I found some errors while starting my computer. Due to this problem I had given my CPU to a shop to repair it I don't know what he has done to my CPU but I only know that finally I got my CPU with Ubuntu 13.04. The technician was unable to make any partition and I also think that he had installed 13.04 over 12.04 and so now my computer is showing some error when I'm starting my computer the error is as follows: error: attempt to read or write outside of the disk 'hd0'. grub rescue _ Before showing this error, few times my computer was working very slow. So kindly someone tell me that is there any way by which I can start my computer. Please also tell me that what things I have to keep in mind while using Ubuntu so that in future I find no difficulties(errors) while using Ubuntu.

• Is an 'if password == XXXXXXX' enough for minimum security?

  - by Prof Plum

  If I create a login for an app that has middle to low security risk (in other words, its not a banking app or anything), is it acceptable for me to verify a password entered by the user by just saying something like: if(enteredPassword == verifiedPassword) SendToRestrictedArea(); else DisplayPasswordUnknownMessage(); It seems to easy to be effective, but I certainly would not mind if that was all that was required. Is a simple check on username/password combo enough? Update: The particular project happens to be a web service, the verification is entirely server side, and it is not open-source. Does the domain change how you would deal with this?

• mouse and mousepad not working properly

  - by snake

  Ubuntu 12.04 LTS Samsung Q35 The mouse pad has stopped working, only the buttons work. The external mouse is also behaving very oddly, the mouse pointer works, but the button is not working properly, it has to be pressed many times or held down to select anything, and when anything that I select behaves as though the mouse is being clicked all the screen, settings will keep changing, the page will scroll, sliders will move up and down, tabs will toggle etc, so everything is unusable with the mouse, cannot even use the browser as it keeps scrolling the page up and down. I have tested the mouse on another computer, and it works fine. Please bear in mind that I am also a complete Linux novice, I installed Ubuntu on an old laptop for my kids, that is the limit of my experience.

• How can I access old KMail emails after upgrading to Ubuntu 11.10?

  - by Gary Kleppe

  I initially installed Ubuntu 11.04 and used KMail for my email. All well and good. Then I upgraded to Ubuntu 11.10. Presumably an upgrade of KMail took place as part of this. Now KMail won't even run; when I try, it tells me "Failed to fetch the resource collection" and crashes. I don't mind switching to another email client, but I'd very much like to be able to recover all of the emails I have stored in KMail. Any suggestions on how to do this? Thanks for any help anyone can provide.

• Why I loose my page rank after 301 redirect?

  - by rajesh.magar

  As we all know Google treat sub-domain as completely separate domain so we have to fight for both, to get ranked in search results. Right! So one of my client website was like they having "example.com" and "Blog.example.com". So in mind to keep all stuff in one place we redirect "blog.example.com" to "example.com/blog/" But in this case we where loose our pagerank and still wondering where we went wrong or it just take few more time to showoff. so what is the reason behind this will be. Thanks in advance.

• Switching domains in one's career?

  - by rocknroll

  I have been a C++,Qt programmer for the last 3.5 years and have hit a plateau in terms of doing something new. Work has been repetitive and routine. I personally believe it is time to move on but off late I am getting more offers in mobile development like Android,Iphone etc. The latest offer I have is for objective-C based profile. I do not have the slightest idea about objective-C apart from that it is Object oriented C resembling C++ but not exactly a clone. Questions in my mind are --what are the pros/cons of this careers switch or for any such switch? --Is it good for one's career to change domains after sometime? --How difficult it is to get back to one's previous area of proficiency? Thanks

• google maps based desktop application

  - by dramaticlook

  I want to build a desktop application which has google maps embedded to it. This app should have a thread to read coordinate data online a usb microphone to use. This application will move the google map markers to their new locations based on the data retrieved from online connections on each refresh. As far as I know gmaps has a javascript API so the first idea in my mind was to embed this mapview into a java applet. So the application will run on a browser. Im not sure if this will work. Do you guys have any idea about this or any other advices you might have? Thanks in advance!!!

• Can we ask idea of software?

  - by jailed abroad

  I am new to Programmers Stack Exchange. I have read the faq. I have a basic question here that can I ask about the idea of developing software. Just for sake of example, I have started a job in software house and my CEO hands me a project. And I have no idea or flow chart in my mind through which I would develop that application. For example client needs an E-diary. I have idea of WPF but lacking flow of app. So my question is can I ask about the app that "what would be the idea to develop the application"?

• How to set up a mail server on Linux only for sending admin/debug emails?

  - by ChocoDeveloper

  I need to send server reports to myself from my remote servers, and I don't mind them going to spam, so I don't need SPF, DKIM, etc. I tried using mailutils to send something like this: uptime | mail -s "uptime" [email protected], but the emails don't go through. In /var/mail/root I received a message saying the HELO was invalid. So then I tried also adding -r root@my-ip, and now I don't get any error messages but I don't receive the email either. How can I do this?

• "Failed to mount Windows share" error in Samba

  - by Ranjith R

  This is the situation. There are 3 machines in the office. The Operating systems on them are respectively, Linux mint Ubuntu 12.04 Windows Vista The Ubuntu (#2) machine is supposed to be the common file server between the machines #1 and #3. Machine #2 has two hard disks. One is a 500 GB NTFS empty drive and the other is a 160 GB ext4 drive. My plan is to make the 500 GB as the file sharing disk. When I share a folder like ~/Documents using Nautilus context menu on machine #2, I can access the files easily on both #1 and #3, but when I try to share some folder on 500 GB disk, I get an error on machine #1 that says Failed to mount windows share I do not mind formatting the drive to ext4 if needed, but I am sure that something simple is wrong. EDIT I took @Marty's comment as a hint and used ntfs-config to configure automount of that partition. It is working now. Thanks

• What is the difference between _Procedural Generation_ and _Random Generation_?

  - by U-No-Poo

  Today, I got into an argument about the term "procedural generation". My point was that its different from "classic" random generation in that procedural generation is based on a more mathematical, fractal-based, algorithm leading to a more "realistic" distribution and the usual randomness of most languages are based on a pseudo-random-number generator, leading to an "unrealistic", in a way, ugly, distribution. This discussion was made with a heightmap in mind. The discussion left me somehow unconvinced about my own arguments though, so, is there more to it? Or am I the one who is, in fact, simply wrong?
