  • Reporting Solution in PHP / CodeIgniter - Server side logic vs client side

    - by dot
    I'm building a report for an end user. They would like to see a list of all widgets... but then also like to see widgets with missing attributes, like missing names, or missing size. So i was thinking of creating one method that returns json data containing all widgets... and then using javascript to let them filter the data for missing data, instead of requerying the database. Ultimately, they need to be able to save all "reports" (filtered versions of data) inside a csv file. These are the two options I'm mulling over: Design 1 Create 3 separate methods in my controller/model like: get_all_data() get_records_with_missing_names() get_records_with_missing_size() And then when these methods are called, I would display the data on screen and give them a button to save to csv file. Design 2 Create one method called get_all_data() and then somehow, give them tools in the view to filter the json data using tables etc... and then letting them save subsets of the data. The reality is, in order to display all data, I still need to massage the data, and therefore, I know which records are missing attributes. So i'd rather not create separate methods by each filter. I'm not sure how I would do that just yet but at this point, i would like to know some pros/cons of each method. Thanks.

  • The Start of a Blog

    - by dbradley
    So, here's my new blog up and running, who am I and what am I planning to write here?First off - here's a little about me:I'm a recent graduate from university (coming up to a year ago since I finished) studying Software Engineering on a four year course where the third year was an industrial placement. During the industrial placement I went to work for a company called Adfero in a "Technical Consultant" role as well as a junior "Information Systems Developer". Once I completed my placement I went back to complete my final year but also continued in my developer role 2/3 days a week with the company.Working part time while at uni always seems like a great idea until you get half way through the year. For me the problem was not so much having a lack of time, but rather a lack of interest in the course content having got a chance at working on real projects in a live environment. Most people who have been graduated a little while also find this - when looking back at uni work, it seem to be much more trivial from a problem solving point of view which I found to be true and I found key to uni work to actually be your ability to prove though how you talk about something that you comprehensively understand the basics.After completing uni I then returned full time to Adfero purely in the developer role which is where I've now been for almost a year and have now also taken on the title of "Information Systems Architect" where I'm working on some of the more high level design problems within the products.What I'm wanting to share on this blog is some of the interesting things I've learnt myself over the last year, the things they don't teach you in uni and pretty much anything else I find interesting! My personal favorite areas are text indexing, search and particularly good software engineering design - good design combined with good code makes the first step towards a well-written, maintainable piece of software.Hopefully I'll also be able to share a few of the products I've worked on, the mistake I've made and the software problems I've inherited from previous developers and had to heavily re-factor.

  • Computers on preexisting Windows 2008 domain accepting accounts from Samba3/4 domain

    - by Ivan Vucica
    I have a web application written in PHP where I would like to allow existing users to log into Windows computers, too. Re-hash of their passwords is doable (by requesting them to change the password). And to solve desync of passwords, I intend to have webapp authenticate users primarily against the domain. I don't want to give webapp users accounts on the existing domain, which we can call example.local. Instead, I want to provide them accounts on a new domain, let's call it webapp.example.local. From some research I have done, setting up a Samba4 domain and joining computers into this webapp.example.local domain would be one way to allow webapp users to log in. But, the computers should be members of the example.local domain. How can I get computers that are members of and are authenticating against Windows 2008-based example.local to also authenticate users against webapp.example.local? Magic keywords seem to be "trust relationship", "forest", etc, but at this point I haven't found a concrete example on how to establish this trust.

  • Save a single web page (with background images) with Wget

    - by mikael
    I want to use Wget to save single web pages (not recursively, not whole sites) for reference. Much like Firefox's "Web Page, complete". My first problem is: I can't get Wget to save background images specified in the CSS. Even if it did save the background image files I don't think --convert-links would convert the background-image URLs in the CSS file to point to the locally saved background images. Firefox has the same problem. My second problem is: If there are images on the page I want to save that are hosted on another server (like ads) these wont be included. --span-hosts doesn't seem to solve that problem with the line below. I'm using: wget --no-parent --timestamping --convert-links --page-requisites --no-directories --no-host-directories -erobots=off http://domain.tld/webpage.html

  • MVC: How to Implement Linked Views?

    - by cw'
    I'm developing a java application to visualize time series. I need (at least) three linked views, meaning that interaction with one of them updates the others. The views are: A list represents the available and currently selected time series. The selected time series are used as input for subsequent computations. Changing the selection should update the other views. A line chart displays the available and selected time series. Time series should be selectable from here by clicking on them. A bar chart shows aggregated data on time series. When zooming in to a period of time, the line chart should zoom in to the same period (and vice versa). How to implement this nicely, from a software engineering point of view? I.e. I'd like to write reusable and clear, maintainable code. So I thought of the MVC pattern. At first I liked the idea of having the three view components observing my model class and to refresh views upon being notified. But then, it didn't feel right to store view related data in the model. Storing e.g. the time series selection or plot zoom level in the model makes implications about the view which I wouldn't want in a reusable model. On the other hand, having the controllers observe each other results in a lot of dependencies. When adding another view, I'd have to register all other views as observer of the new view and vice versa, passing around many references and introducing dependencies. Maybe another "model" storing only view-related data would be the solution?

  • netmask: command not found

    - by Ian R.
    I purchased a new server with a few ip's so I modified the /etc/network/interfaces file recently so that my ip's can go live. While editing that file I created a backup and deleted the original file. I recreated the interfaces file using the touch command and gave +x permissions but now, when trying to restart the interface (/etc/network/interfaces restart) I get all sorts of errors: /etc/network/interfaces: line 10: iface: command not found /etc/network/interfaces: line 11: address: command not found /etc/network/interfaces: line 12: netmask: command not found /etc/network/interfaces: line 13: auto: command not found Can any1 point what I forgot to do? Thanks.

  • Keep cube spinning after fling

    - by Zero
    So I've been trying to get started with game development for Android using Unity3D. For my first project I've made a simple cube that you can spin using touch. For that I have the following code: using UnityEngine; using System.Collections; public class TouchScript : MonoBehaviour { float speed = 0.4f; bool canRotate = false; Transform cachedTransform; public bool CanRotate { get { return canRotate; } private set { canRotate = value; } } void Start () { // Make reference to transform cachedTransform = transform; } // Update is called once per frame void Update () { if (Input.touchCount > 0) { Touch touch = Input.GetTouch (0); // Switch through touch events switch (Input.GetTouch (0).phase) { case TouchPhase.Began: if (VerifyTouch (touch)) CanRotate = true; break; case TouchPhase.Moved: if (CanRotate) RotateObject (touch); break; case TouchPhase.Ended: CanRotate = false; break; } } } bool VerifyTouch (Touch touch) { Ray ray = Camera.main.ScreenPointToRay (touch.position); RaycastHit hit; // Check if there is a collider attached already, otherwise add one on the fly if (collider == null) gameObject.AddComponent (typeof(BoxCollider)); if (Physics.Raycast (ray, out hit)) { if (hit.collider.gameObject == this.gameObject) return true; } return false; } void RotateObject (Touch touch) { cachedTransform.Rotate (new Vector3 (touch.deltaPosition.y, -touch.deltaPosition.x, 0) * speed, Space.World); } } The above code works fine. However, I'm wondering how I can keep the cube spinning after the user lifts his finger. The user should be able to "fling" the cube, which would keep spinning and after a while would slowly come to a stop due to drag. Should I do this using AddForce or something? I'm really new to this stuff so I'd like it if you guys could point me in the right direction here :) .

  • How does the TuneIn mobile application resume a live stream, when the connection breaks?

    - by navnav
    So I have this TuneIn application on my phone, which allows me to listen to many radio stations. It also allows me to rewind and pause the live stream, which I know is doable with today's technology. What gets me puzzled, though, is how when the internet connection breaks, the live stream will stop, but, when the connection comes back, the app can just pick up from where it broke. Why it gets me puzzled is because there is no way for the app to cache the live stream when the net connection has gone, yet it can start the live stream back up, from where it broke. Is there is possible to start a live stream, at a specific point of the audio stream? Or are they using some other method?

  • Migrating My GWB Blog Over To WordPress

    - by deadlydog
    Geeks With Blogs has been good to me, but there are too many tempting things about Word Press for me to stay with GWB.  Particularly their statistics features, and also I like that I can apply specific tags to my posts to make them easier to find in Google (and I never was able to get categories working on GWB). The one thing I don’t like about WordPress is I can’t seem to find a theme that stretches the Content area to take up the rest of the space on wide resolutions…..hopefully I’ll be able to overcome that obstacle soon though. For those who are curious as to how I actually moved all of my posts across, I ended up just using Live Writer to open my GWB posts, and then just changed it to publish to my WordPress blog.  This was fairly painless, but with my 27 posts it took probably about 2 hours of manual effort to do.  Most of the time WordPress was automatically able to copy the images over, but sometimes I had to save the pics from my GWB posts and then re-add them in Live Writer to my WordPress post.  I found another developers automated solution (in alpha mode), but opted to do it manually since I wanted to manually specify Categories and Tags on each post anyways.  The one thing I still have left to do is move the worthwhile comments across from the GWB posts to the new WordPress posts. The largest pain point was that with GWB I was using the Code Snippet Plugin for Live Writer for my source code snippets, and when they got transferred over to WordPress they looked horrible.  So I ended up finding a new Live Writer plugin called SyntaxHighlighter that looks even nicer on my posts If anybody knows of a nice WordPress theme that stretches the content area to fit the width of the screen, please let me know.  All of the themes I’ve found seem to have a max width set on them, so I end up with much wasted space on the left and right sides.  Since I post lots of code snippets, the more horizontal space the better! So if you want to continue to follow me, my blog's new home is now at https://deadlydog.wordpress.com

  • Acer S3 SSD and HD Deleted partitions?

    - by user207784
    I'm new to Linux and Ubuntu, and I think I have a problem. I have an Acer Aspire S3 with 20GB SSD and 320GB HD. I installed Ubuntu 12.04 64bit on it today, and when it asked about partitions, without knowing better, I erased the partitions. There is some information at https://help.ubuntu.com/community/AspireS3 about using the SSD and HD efficiently, but since I deleted the partitions, I don't know what to do. How can I recreate the partitions mentioned in the above link so that I can take advantage of having SSD and HD? I installed GParted, but I don't know what I should do now, and I don't want to screw things up further. I greatly appreciate any help that can be offered me. EDIT: I was playing with GParted, and I just realized that I can see dev/sda and dev/sdb, so perhaps I didn't do something horrible to my partitions. I am also sorry for asking such (dumb?) questions. At this point, is there a way to tell whether I have actually screwed up my partitions? Thanks, Joe

  • How would you diagnose an integrated network card that doesn't show up on the device list?

    - by Tomer Gabel
    I've been setting up a server based around a Gigabyte GA-G33M-DS2R motherboard (G33, PCH9R with integrated Realtek 811B network device. I've enabled it in the BIOS, but it doesn't show up in the pre-boot PCI device list, isn't recognized by Windows (even after installing the chipset and networking drivers) and doesn't even show up via lspci. I've tried cycling power, disabling, cycling again, enabling, cycling again etc. to no avail. I'm sort of at a loss at this point; the board isn't under warranty anymore, but I'd rather not have to replace it. Any advice would be greatly appreciated...

  • Using template questions in a technical interview

    - by Desolate Planet
    I've recently been in an argument with a colleague about technical questions in interviews. As a graduate, I went round lots of companies and noticed they used the same questions. An example is "Can you write a function that determines if a number is prime or not?", 4 years later, I find that particular question is quite common even for a junior developer. I might not be looking at this the correct way, but shouldn't software houses be intelligent enough to think up their own interview questions? I've been to about 16 interviews as a graduate and the same questions came up in about 75% of them. This leads me to believe that many companies are lazy and simply Google: 'Template questions for interviewing software developers' and I look down on that. Question: Is it better to use a set of questions off some template or should software houses strive to be more original and come up with their own interview material? From my point of view, if I failed an interview and went off and looked for good answers to the questions I messed up on, I could fly through the next interview if the questions are the same.

  • DNS security (hijacking?)

    - by Jongsma
    I am hosting my website on Linode and am also using their DNS/naming servers. (ns1.linode.com etc.) It occurred to me that I never have had to authenticate that the domain is mine when I added it to the domain to the DNS manager, or at any other point. I now wonder whether it would be possible for other Linode users to 'hijack' my domain by simply adding the same domain zone and pointing it to their own server. I wouldn't know how Linode could determine which are the real/authentic records. How can I be sure this doesn't happen?

  • C++: calling non-member functions with the same syntax of member ones

    - by peoro
    One thing I'd like to do in C++ is to call non-member functions with the same syntax you call member functions: class A { }; void f( A & this ) { /* ... */ } // ... A a; a.f(); // this is the same as f(a); Of course this could only work as long as f is not virtual (since it cannot appear in A's virtual table. f doesn't need to access A's non-public members. f doesn't conflict with a function declared in A (A::f). I'd like such a syntax because in my opinion it would be quite comfortable and would push good habits: calling str.strip() on a std::string (where strip is a function defined by the user) would sound a lot better than calling strip( str );. most of the times (always?) classes provide some member functions which don't require to be member (ie: are not virtual and don't use non-public members). This breaks encapsulation, but is the most practical thing to do (due to point 1). My question here is: what do you think of such feature? Do you think it would be something nice, or something that would introduce more issues than the ones it aims to solve? Could it make sense to propose such a feature to the next standard (the one after C++0x)? Of course this is just a brief description of this idea; it is not complete; we'd probably need to explicitly mark a function with a special keyword to let it work like this and many other stuff.

  • Computer Locks Up Completely When Resuming From Standby

    - by kcoppock
    Okay, so I'm having a strange issue lately with my desktop, and off the top of my head I'm not sure what the problem is, so I'm hoping for some ideas on how to track down the cause. First, my PC: AMD Phenom 9600 Quad-Core 2.4 GHz 4 GB DDR2 160 GB boot HDD 1 TB & 120 GB secondary HDD Nvidia GeForce 8600 GTS Windows 7 Professional 64-bit I have my power settings as follows: Turn off the display: 10 minutes Turn off hard disk: 20 minutes Sleep after: Never After a while, I'll come back to use my computer again, wiggle the mouse, and the screen comes back on like normal, but the desktop is unresponsive. I can move the cursor, but nothing responds to clicks or keyboard entry. If I click a few times with the mouse, the computer eventually locks up completely and the mouse cursor stops moving as well. After I restart, everything works just fine. Is there a log you recommend checking or really any suggestions would be welcome at this point. Thanks!

  • Reformatting and version control

    - by l0b0
    Code formatting matters. Even indentation matters. And consistency is more important than minor improvements. But projects usually don't have a clear, complete, verifiable and enforced style guide from day 1, and major improvements may arrive any day. Maybe you find that SELECT id, name, address FROM persons JOIN addresses ON persons.id = addresses.person_id; could be better written as / is better written than SELECT persons.id, persons.name, addresses.address FROM persons JOIN addresses ON persons.id = addresses.person_id; while working on adding more columns to the query. Maybe this is the most complex of all four queries in your code, or a trivial query among thousands. No matter how difficult the transition, you decide it's worth it. But how do you track code changes across major formatting changes? You could just give up and say "this is the point where we start again", or you could reformat all queries in the entire repository history. If you're using a distributed version control system like Git you can revert to the first commit ever, and reformat your way from there to the current state. But it's a lot of work, and everyone else would have to pause work (or be prepared for the mother of all merges) while it's going on. Is there a better way to change history which gives the best of all results: Same style in all commits Minimal merge work ? To clarify, this is not about best practices when starting the project, but rather what should be done when a large refactoring has been deemed a Good Thing™ but you still want a traceable history? Never rewriting history is great if it's the only way to ensure that your versions always work the same, but what about the developer benefits of a clean rewrite? Especially if you have ways (tests, syntax definitions or an identical binary after compilation) to ensure that the rewritten version works exactly the same way as the original?

  • How to connect two subnet with Windows Server?

    - by 9dan
    Hello, I have some work to do in a small office. This office has two separate Internet connections. One is a kind of DSL line and connected through the Internet sharing router (DHCP). One is a leased line with public IP adresses (No DHCP). This leased line provide only 30 IP addresses and the gateway is provided by the ISP. Some workers use private IP provided by the router, some workers use manually setup public IP. There is a Windows 2008 R2 server with two NICs, connected to each lines. I want to connect/merge(?)/bridge(?) two subnet with this server so that users from the different subnet can access each other. How can I accomplish this? Something like, add gateway function to this server and public IP users change the gateway to point this server.. It it possible ? Sorry for my rambling. Thanks in advance.

  • Word 2007 "Out of Memory or Disk Space" Error on launch.

    - by Adam
    Word 2007 is installed on a Vista Home Premium machine and whenever it starts up it opens what appears to be a dynamic installer to do something and then throws up the "Out of Memory or Disk Space" error. Word 2007 never completes starting up. Reinstalling Word hasn't helped and if I can avoid reinstalling Windows until Windows 7 is released and get Word working in the mean time, that would be ideal. I've been looking around for a solution, once of which seemed to point to a problem with the user account. I created a second user on the machine and Word still had the same problem. The other solution that seems possible is a corrupted normal.dot/normal.dotm file. However, even in the location it should be, I can't seem to find it. Am I going in the right direction with this? Is there another solution I haven't come across that will fix this? If it is possible that renaming normal.dot/normal.dotm how can I find it?

  • What's wrong with cplusplus.com?

    - by Kerrek SB
    This is perhaps not a perfectly suitable forum for this question, but let me give it a shot, at the risk of being moved away. There are several references for the C++ standard library, including the invaluable ISO standard, MSDN, IBM, cppreference, and cplusplus. Personally, when writing C++ I need a reference that has quick random access, short load times and usage examples, and I've been finding cplusplus.com pretty useful. However, I've been hearing negative opinions about that website frequently here on SO, so I would like to get specific: What are the errors, misconceptions or bad pieces of advice given by cplusplus.com? What are the risks of using it to make coding decisions? Let me add this point: I want to be able to answer questions here on SO with accurate quotes of the standard, and thus I would like to post immediately-usable links, and cplusplus.com would have been my choice site were it not for this issue. Update: There have been many great responses, and I have seriously changed my view on cplusplus.com. I'd like to list a few choice results here; feel free to suggest more (and keep posting answers). As of June 29, 2011: Incorrect description of some algorithms (e.g. remove). Information about the behaviour of functions is sometimes incorrect (atoi), fails to mention special cases (strncpy), or omits vital information (iterator invalidation). Examples contain deprecated code (#include style). Inexact terminology is doing a disservice to learners and the general community ("STL", "compiler" vs "toolchain"). Incorrect and misleading description of the typeid keyword.

  • Is there a method to export the URLs of the open tabs of a Firefox window?

    - by hekevintran
    If I have a Firefox window open that contains 10 tabs, is there a way in Firefox or by a plug-in to get the URLs of those 10 tabs as a text file or some other format? Right now if I want to do this I need to copy the URL of tab A, paste it somewhere, move to tab B, and repeat. I could also bookmark all the tabs into a folder and export that, but that seems like such a hassle. If there is no such method, could someone point me to some documents that describe the basics of writing a Firefox plug-in. I am willing to write this myself if there is no "standard" way.

  • Picking Core Language For Large Scale Web Platform

    - by ryanzec
    Now I have work with PHP and ASP.NET quite a bit and also played around few other language for web development. I am now at a point where need to start building a backend platform that will have the ability to support a large set of applications and I am trying to figure out which language I want to choose as my core language. When I say core language I mean the language that the majority of the backend code is going to be in. This is not to say that other languages won't be used because my guess is that they will but I want a large majority of the code (90%-98%) to be in 1 language. While I see to benefit of using the language that is best for the job, having 15% in php, 15% in ASP.NET, 5% in perl, 10% in python, 15% in ruby, etc… seems like a very bad idea to me (not to mention integrating everything seamlessly would probably add a bit of overhead). If you were going to be building a large scale web platform that need to support multiple applications from scratch, what would you choose as your core language and why?

  • Worker processes not starting in IIS 7.5. What should I check?

    - by locster
    I have a Windows 7 machine (Windows version 6.1.7601 SP1 Build 7601) with IIS installed. At some point the installation appears to have become 'corrupted' in some way, as any requests are now met with the message: Service Unavailable HTTP Error 503. The service is unavailable. In IIS manager IIS is started and the app pool I am using reports itself as 'Started', yet there is no w3wp.exe process listed in the process list in task manager (I am a local admin and have clicked the 'Show processes from all users' button. I have enabled logging for the web site (at default location of %SystemDrive%\inetpub\logs\LogFiles), but this folder is empty. I am assuming that this log output is written by w3wp.exe as it handles requests (no w3wp.exe, no log file?). Presumably there is another layer of request handling that is responsible for starting the worker processes, does thsi layer have log files I can check, and/or can I uninstall/re-install that layer? Thanks.

  • Building a List of All SharePoint Timer Jobs Programmatically in C#

    - by Damon Armstrong
    One of the most frustrating things about SharePoint is that the difficulty in figuring something out is inversely proportional to the simplicity of what you are trying to accomplish.  Case in point, yesterday I wanted to get a list of all the timer jobs in SharePoint.  Having never done this nor having any idea of exactly how to do this right off the top of my head, I inquired to Google.  I like to think my Google-fu is fair to good, so I normally find exactly what I’m looking for in the first hit.  But on the topic of listing all SharePoint timer jobs all it came up with a PowerShell script command (Get-SPTimerJob) and nothing more. Refined search after refined search continued to turn up nothing. So apparently I am the only person on the planet who needs to get a list of the timer jobs in C#.  In case you are the second person on the planet who needs to do this, the code to do so follows: SPSecurity.RunWithElevatedPrivileges(() => {    var timerJobs = new List();    foreach (var job in SPAdministrationWebApplication.Local.JobDefinitions)    {       timerJobs.Add(job);    }    foreach (SPService curService in SPFarm.Local.Services)    {       foreach (var job in curService.JobDefinitions)       {          timerJobs.Add(job);       }     } }); For reference, you have the two for loops because the Central Admin web application doesn’t end up being in the SPFarm.Local.Services group, so you have to get it manually from the SPAdministrationWebApplication.Local reference.

  • Acer Aspire 5542G overheating with ubuntu/kubuntu 12.04

    - by james
    I have an Acer Aspire 5542G laptop purchased couple of years ago. All these days, i used windows 7 on it . Then I tried ubuntu 12.04 . Everything was fine except the overheating issue. I updated ubuntu with all security fixes and available updates but nothing solved the problem. With idle use like internet browsing, the cpu fan speeds up a lot and i can feel very hot air coming from the vent (comparable to playing serious 3d game in windows). But it will not go to a point of freeze and shutdown. But as long as im using it, with no intensive tasks at all, the laptop stays too hot. This wasn't the case with windows7. In windows 7 the fan will not rotate at all with normal use. I heard there was manufacturing defect with some acer laptops, but i think it wasn't the case with my laptop since windows7 runs perfectly. I updated the bios to latest version. I cleaned dust in the vents. I tried kubuntu 12.04 up-to-date. Nothing solved the issue. My laptop specs are: CPU : AMD turion2 x2 M500 @ 2.2GHz GPU : AMD Mobility Radeon HD4570 3GB RAM and 320GB hard disk.
