  • Storing Projects on Google Drive (Cloud)

    - by JamesKraw
    I've started using Google Drive for my cloud needs and backing up pretty much everything. I've got the app installed so it auto-sync's all my content in most things. My question is this, I am currently coding for iOS (although this applies to any coding project) and am split on storing my project files on Google Drive while using sync. My theory is that if I did use it, I'd never have to worry about system crashes or lost code before backups, but if I do use it it will be sync'ing a-lot and I thought there might be problems with it detecting changes and trying to sync for example half way through compiling. Bandwidth isn't an issue as I have fast connection and unlimited monthly allowance. Has anyone ever used this, or similar cloud-based sync'ing (dropbox etc) for this and knows whether it works or not or whether there are any potential problems etc.

  • Why can't I change my icon theme in gnome-classic?

    - by Shibumi
    I'm running Ubuntu 11.10 (updated) and gnome-classic (I missed it :3) I've tried setting my icon theme, GTK theme, and window theme in gnome-tweak-tool, as well as Ubuntu Tweak, gconf-editor, and dconf-editor. Even though it shows my selections are selected, the icons and themes stay the same. Any Help would be greatly appreciated! Update: I've tested things out on gnome-shell and Unity, and I have full control over icons and such in those environments, but still no control in gnome-classic. I would really like to figure this out. Update 2: It seems that after uninstalling Unity that I have full control over everything. Any explanation (since Unity or some part of it seemed to be the cause) would be really nice.

  • get_hosts script being ignored in LTSP setup on Ubuntu 12.04

    - by Shwetav
    We had a home-grown LTSP load-balancer based on LDM_SERVER and get_hosts in Ubuntu 10.04. After upgrading to Ubuntu 12.04, everything worked fine except that get_hosts is being ignored completely. If we put space delimited list of servers as LDM_SERVER in lts.conf, users can choose a server during login and things work fine. Tried both locations below without any luck so far: 1. /var/lib/tftpboot/ltsp/i386/get_hosts 2. /opt/ltsp/i386/etc/get_hosts Any pointers would be greatly appreciated.

  • Resource Managers - Are they any good?

    - by The Communist Duck
    Hey. I've seen many a time in source code, things like this [well, this is more of a pseudo C++ idea of mine] type defshared_ptr ResourcePtr;// for ease ResourcePtr sound1 = resourceManager.Get("boom.ogg"); sound1-Play(); ResourcePtr sprite = resourceManager.Get("sprite.png"); I was just wondering how useful a class like this was, something that: Loaded media files Stored them in memory Did this at the start of a level - loading screen. Cleaned up Rather than having a system of: Resources are held by entities only, or loose. Responsible for own load into memory. The first is a 'manager' as such; something I feel indicates it's wrong to use. However, it allows for something like a vector of resource names to be passed, rather than having to scramble around finding everything that needs to be loaded.

  • What can I learn to build a (kind of) recommendation system?

    - by lsmagalhaes
    I'm learning how to develop an android app (nothing serious, just for learning and fun), so I devised the following goal: an app that learns with users actions and, some time later, starts to suggest some useful things. For example: The user add some notes daily, in the morning, and mark some of them as done generally on thursdays and sundays, at evening. Based on that behaviour and the relation of the notes marked as done, the app will prioritize notes that are more propense to be marked, and avoid notifying in days where no note is marked. This is a silly example but I think it ilustrates well what I want to do. I know this is a matter of machine learning, but I don't know where I should start learning. To anyone interested, I'm build a backend in Python, so any libraries or frameworks in this language are very welcome. The frontend, by the way, is sencha touch + phonegap.

  • Implementing cache system in Java Web Application

    - by TGM
    I worked with JPA (Eclipselink implementation) and Hibernate. As I understand these two have great caching systems. I am interested in caching in a Web application and in order to better understand the process I'm trying to implement something on my own. Sadly, I cannot find any in depth documentation about this subject. I'm interested in things like high scalability, sharing memory on different machines and other important theoretical matters. Is there any tutorial or open project I could check out? Thank you! *LE: * I want to cache DB information in POJOs just like JPA or Eclipselink

  • A programmer who doesn't get to program - where to turn? [closed]

    - by Just an Anon
    I'm in my mid 20's, and have been working as a full time programmer / developer for the last ~6 years, with several years of part-time freelancing before this, and three straight years of freelancing in the middle of this short career. I work mostly with PHP and the Drupal framework. By and large, I focus on programming custom pieces of functionality; these, of course, vary greatly from project to project. I've got years of solid experience with OOP (have done some Java & C# years ago, too) including intensive experience with front-end development, and even some design work. I've lead small teams (2-4 people) of developers. And of course, given the large amount of freelancing, I've got decent project- & client-management skills. My problem is staying motivated at any place of employment. In the time mentioned I've worked (full-time) at six local companies. The longest I've stayed at any company was just over a year. I find that I'll get hired and be very excited and motivated for the first few months, but the work quickly gets "stale." By that I mean that the interesting components (ie. the programming) get done, and the rest of the work turns into boring cleanup (move a button, add text, change colours, add a field). I don't get challenged, and I don't feel like I'm learning anything new. This happens repeatedly time and time again, and I always end up leaving for either a new opportunity, or to freelance. I'm wondering if perhaps I've painted myself into a corner with the rather niche work market (although with very high demand and good compensation) and need to explore other career choices. Another possibility is that I may be choosing the wrong places of employment, mostly small agencies, and need to look into working for a larger, more established firm. I find programming, writing code, and architecting solutions very rewarding. When I'm working on an interesting problem I lose all sense of time and 14-16 hours can fly by like minutes. I get the same exciting feeling when I'm doing high-level planning of a complex system, breaking up the work and figuring out how everything will tie-in together. I absolutely hate doing small, "stupid" changes that pose no challenge, yet seem to make up more and more of my work. I want to find a workplace where I will get to work on such tasks, be challenged, and improve in all areas of product development. This maybe a programming job, management, architecture of desktop apps, or may be managing a taco stand on a beach in Mexico - I don't know, and I need some advice and real-world feedback. What are some job areas worth exploring? The requirements are fairly simple: working with computers interacting with others challenging decent pay (I'm making just short of 90k / year with a month of vacation & some benefits, and would like to stay in this range, but am willing to take a temporary cut in pay for a more interesting position) Any advice would be much appreciated!

  • SEO - A Crash Course

    Search engine optimization, otherwise commonly referred to SEO, is a way to make web content appear as high as possible in search engine rankings. Here, we'll discuss a number of ways you can use this valuable tool to your advantage for your website. Using text on your website and on titles and things of this nature will be used to create placement on web pages. Keywords repeated throughout a page will bring it up towards the top based on the phrase a search engine user types into the search box. You will want to use a keyword phrase in your title tag, the website URL, and about a 4-6% keyword phrase density in your overall page text. Additional locations that these keyword phrases are important include within inbound links, within headings, in the beginning of a document, in alternative text tags, and in metatags.

  • Port flash game to native android

    - by wirate
    Alright here is the problem: the creators of a quite popular flash-based game have asked me to port their game to Android. They are not interested in any other platforms so we don't need to be worrying about iOS or PC. They want the best performance on just Android (I guess that's the point of porting a flash-based game. They could have just went with it) They found Unity 'slow'. How would the performance (on android) of other engines compare? Are they expecting too much i.e. finding Unity slow? I am in favor of Unity since development is a little easier with more things being visual (I am not experienced as you might have guessed). This would be an example of the type of game I am to port Thanks!

  • When must arbitrary precision arithmetic functions be used in PHP?

    - by Tjorriemorrie
    My colleague uses the Binary Calculator functions in bandwidth calculations; as much as terrabytes, and with percentage splitting on allocation. His usage of these functions appears correct in order not to lose a byte; although he seems to be using them now for everything. The manual only says: For arbitrary precision mathematics PHP offers the Binary Calculator which supports numbers of any size and precision, represented as strings. How much is any size? Is it really necessary? How big is the default float in PHP? Are there any good advice regarding this or things to keep in mind?

  • CSS&ndash;margin or padding

    - by woodbase
    I was beginning the implementation of a new design, and once again I found that my margin property on a div-tag, did not behave as I expected. So I decided to look for best practice when it comes to using margin or padding. What I found was this very short and concise description of the difference between the two: “Margin is on the outside of block elements while padding is on the inside. Use margin to separate the block from things outside it, padding to move the contents away from the edges of the block.” So what is best practice? Well it depends on the context. In my case I should have used padding…

  • Using a texture as an integer array (OpenGL 3.3, shader version 3.3)

    - by Cubic
    I'm trying to have something like an integer array uniform for my fragment shader (I only need read access). Since it's a fairly large chunk of data (not so large that uploading it in every frame would be impossible, but enough to make me want to rather not do it). Essentially I want to just pass it a uniform telling the shader where this "array" is. I believe I can use a 1D texture for this, but I don't know how (actually, I don't know how to do many things because I just can't seem to find a reference for GLSL 3.3, I only ever find references for the C API). This sounds like a rather basic question and I'm sure it's been answered already somewhere, but I keep searching and can't quite find what I'm looking for.

  • in sending with name using ? (counting), how does the process happen? [closed]

    - by sam
    Sometimes expressions has two states. the result of analyses might be two different things but at the end, there might be the same answer(result) for them.(the way we get to the answer is different,but the result is the same) for example: P-Q = M P-T = M in lambda we have two solutions. 1.sending with name. (in ALGOL it have over load) 2.sending with value Example: Q: (?y.(yy) (?x.(xx)a)) 1.sending with name (?x.(xx)a ?x.(xx)a) ((aa)(aa)) 2.sending with value (?y.(yy) aa) ((aa)(aa)) now here is the question, in sending with name that used ? (counting), how does the process happen? How this sending (transmittal) happen? How does it work?

  • Grouping GridView on Windows 8

    It took me a few minutes to get the grouping working on the GridView on my Windows 8 app. I’m sharing what I did just so others can get it working sooner and go by the rest of their work. In VS 2012, I added a Grouped Items Page to my Windows 8 application project. By default, the template will add some sample data, so you can just run it to see how things look. Let’s see what it takes to show our custom data on the page. I’ll stat with the data source. 1: public class Team 2: { 3: public Team( string...(read more)

    I have a Maxtor OneTouch External Harddisk 160gb that i purchased recently. At first my Ubuntu 10.10 could not mount it. I opened disk utility which recognized it but with no filesystem. I proceeded to try formatting it but this error popped up Blockquote Error creating partition table: helper exited with exit code 1: Error calling fsync(2) on /dev/sdb: Input/output error Blockquote I resorted to Gparted. Things turned worse; it wasn't even listed in the list of devices. Does anyone have a solution to this problem? Any help is appreciated.

  • What's New in JMS 2 - Part 1

    - by reza_rahman
    JMS 2 is one of the most significant parts of Java EE 7. One of the principal goals of the JMS 2 API is improving developer productivity by reducing the amount of code to work with JMS by adopting programming paradigms like higher level abstractions, dependency injection, annotations, runtime exceptions, the builder pattern and intelligent defaults. In a recent OTN article, JMS 2 specification lead Nigel Deakin covers the ease-of-use changes in detail. The article is the first of a two part series on JMS 2. For more visual folks, there is my JMS 2 slide deck: What’s New in Java Message Service 2 from Reza Rahman You can also check out the official specification yourself or try things out with the newly released Java EE 7 SDK.

  • In setting up dual Boot with Windows XP and Ubuntu, which OS do I install first?

    - by markl
    I'd like to install both Ubuntu 12.04 and Windows XP on a Dell laptop, and I was thinking about using a dual boot structure, and using the bulk of my hard drive as empty hard drive space to share files between the two operating systems (so choice of file system type is very important in this set-up). The kind of partitioning structure I would like to use is Partition 1 - Ubuntu 12.04 (root) (20GB) Partition 2 - Ubuntu /home (20GB) Partition 3 : Free Space (560GB) Partition 4 : Windows XP (35GB) Partition 5 : SWAP (3GB) (Total Hardrive Capacity is ~640GB) My question is; what is the best way to go about setting up this kind this system? Should I install Windows XP first and setup the partitions, and then install Ubuntu which I believe will install the GRUB bootloader for OS booting choice or Do I install Ubuntu first, setting up the available partitions and then perform a WIndows install? Please let me know if there is anything in this setup that I have left out and should know about, including things related to setting particular partitions as logical or primary, and whether the boot partition and the filesystem partition should actually be two separate partitions.

  • Double equals (Not equality) during assigning Java

    - by FabianCook
    When I tried searching this I would just get things on equality. When I was reading through some documentation for navigation in Android I had come across something I had never seen before. I came across this: mTitle = mDrawerTitle = getTitle(); It almost looks like something you can do in JavaScript where you can take the first not-null variable and assign it to a variable. In JavaScript I would do this: mTitle = mDrawerTitle || getTitle(); And it would return the first not null, in Java, is this double equals usage the equivalent in Java? What is this type of expression called?

  • loadparm.c:4864, leaking memory?

    - by RandomOzzy
    I’m running Ubuntu 14.04 Server with a LAMP stack, Samba, and FTP, no GUI, just SSHing into the server and working on it. I’m having trouble searching down a solution to this issue, but as far as I can Google for it, it might have something to do with Samba. no talloc stackframe at ../source3/param/loadparm.c:4864, leaking memory?? The warning doesn't pop up at any kind of regular intervals or in response to the same or repeated actions. It pops up between things I’m doing - changing directories, editing files, copying stuff, and it often pops up when I first log in. Has anyone got experience fixing this issue?

  • Whats the problem with reporting ?

    Its the reports.   Take this for example, it is a report generated during a demo of Report Builder 3.0 by someone in MS marketing. She says things like “..and you can see easily how my divisions are doing”. No you can’t you’ve just got a bunch of numbers. This is really the issue with reporting systems and especially with Microsoft reporting. The problem is that people think generating a report is about getting lists of numbers onto a page. Reporting services is great at doing that and its very...(read more)

  • gnome-panel has multiple rows -- how to undo that?

    - by towi
    On Ubuntu 12.04 I use openbox with a single "gnome-panel" started. But after trying to configure my two screen in Xinerama mode I got additional rows of panels each time X restarted. And despite I completely reverted to my one-screen-X-config the gnome-panel displayed has 4 rows (4 at top sreen, 4 at bottom) only the outermost row has content, the other 3 are empty there is only one gnome-panel process running some widgets appear 4 times, too, although they run only once when I switch away from openbox using unity I am back to 1 row temporarily What went wrong here? How do I undo that? Things that did not help: rm -Rf .gnome2 .gconf/ .compiz-1/ pkill panel, and restarting it

  • How do you manage all of the information you have learned and found? [closed]

    - by B Seven
    Possible Duplicate: How do you manage your knowledge base? What do you use for personal note taking to keep track of everything you learn? Are you always Googling or searching StackOverflow to answer the same questions? Or searching for and copying and pasting existing code? I feel like I have a poor memory, especially remembering things like syntax. Are there any knowledge management systems that would work well for a programming language or operating system? It would be great if there were a way to save everything I learn in an easy to search system. Does such a thing exist? Maybe you would be able to search by question (How to sort an array?, How to set static IP?), or by tag (sort, array, enumeration, iterator, IP). I know it would be easy to develop my own system, but I thought it would be great to learn what works for other people.

  • Ideas for how to structure a developer class/course? [on hold]

    - by Andy
    Let's say I need to teach a 3-8 week course in programming/development at a technical school (no kids) (regardless of language or technology and the target audience is beginners). I need ideas to make it a awesome class where I : Maximize the students learning and experience Make sure they don't fall a sleep Engage the students Make it exciting! I can always do traditional lecture+exercises and repeat this pattern over and over, but I think this is to old-school. Things I have considered to add to the course are: - Require pair programming - Code-review together with the students I would like suggestions on how to make a modern training class state really awesome?
