• "Google files": Building a web interface to find/ack/grep

  - by user27915816

  I am working on a project where we would like to have build a web interface that gives the user the ability to "Google" files in a directory in a remote machine. For example, the user would type a string in a box, and then the system would find all files that contain that string and present them in the browser. The system would then give the user the ability click on any of the files to open them/display them in the browser. We want to avoid reinventing the wheel if possible, but don't really know where to start (none of us in the team have much experience building websites). What software packages, libraries or tools exist that can help us get this done?

• Looking for parallel programming problem

  - by Chris Lieb

  I am trying to come up with a problem that is easily solvable in a parallel manner and that requires communication between threads for a test. I also am trying to avoid problems that require require random waits, which rules out dining philosophers and producer-consumer (bounded buffer), two of the classics. My goal is for the student to be able to write the program in less than 20-30 minutes in front of a computer not knowing of the problem beforehand. (This is to prevent preparation more than to come up with something novel.) I am trying to stress the communication aspect of the program, though the multi-threaded nature is also important. Does anyone have some ideas? Edit: I'm using Google Go for the language and testing comprehension of the goroutines/channels combo vs an actors library that I authored.

• Are these interview questions too difficult for entry-level C++ positions?

  - by Banana

  I recently had a few interviews for programming jobs within the financial industry. I am looking for entry-level positions as I specify in the cover letter. However I am usually asked questions such as: - all two-letters commands you know in unix - representation of float/double numbers (ieee standard) - segmentation fault memory dump, and related issues - all functions you know to convert string to integer (not just atoi) - how to avoid virtual tables - etc.. Is that the custom? Because I don't think this kind of questions make sense for someone willing to get an entry-level job. Is it totally crazy to think that they should ask more conceptual questions? This is beginning to driving me nuts, honestly. Thanks

• XNA VertexBuffer.SetData performance suggestions

  - by CodeSpeaker

  I have a 3d world in a grid layout where each grid cell contains its separate vertex and index buffer for the mesh/terrain of that cell. When the player moves outside the boundaries of his cell, i dynamically load more cells in his walking direction based on his viewing distance. This triggers x number of vertex and indexbuffer initializations depending on how many cells that needs to be generated and causes the framerate to drop annoyingly during this time. The generation of terrain data is handled in a separate thread and runs smoothly. The vertex and index buffers are added during the update cycle of the game loop. I´ve tried batching the number of cells to be processed to avoid sending too much data at once into the buffers, which worked ok at a shorter viewing distance (about 9 cells to process), but not as well at greater distances with around 30 cells to process. Any idea how i can optimize this?

• Structuring an input file

  - by Ricardo

  I am in the process of structuring a small program to perform some hydraulic analysis of pipe flow. As I am envisioning this, the program will read an input file, store the input parameters in a suitable way, operate on them and finally output results. I am struggling with how to structure the input file in a sane way; that is, in a way that a human can write it easily and a machine can parse it easily. A sample input file made available to me for a similar program is just a stream of comma-separated numbers that don't make much sense on their own, so that's the scenario I am trying to avoid. Though I am giving the details of my particular problem, I am more interested in general input-file structuring strategies. Is a stream of comma-separated values my best bet? Would I be better off using some sort of key:value structure? I don't know much about this, so any help will probably put me in a better track than I am now.

• How to build list of items available in World of Warcraft?

  - by Cyclops

  There are a number of non-Blizzard sites that show a complete list of available items in World of Warcraft (such as wowhead, etc). I would like to know the best (easiest) way to compile a similar list. I believe some sites are based on user-entered input, which I would like to avoid. Looking at the lua API, it seems that there are functions to get a list of items, but it's not clear if I can just download everything (I remember a reference to throttling somewhere, can't find it now). Does anyone have code samples that would do this, or links to source? Also, Eve Online has made a database of items available (and I do mean SQL database file for download, not the Armory) - is there anything similar for Wow? I'm just looking for the names and stats, not the graphic icons.

• How to be anonymous on IPV6 protocol by not using MAC address in EUI-64?

  - by iugamarian

  The IPV6 protocol has a feature called "Extended Unique Identifier" or EUI-64 witch in short uses the MAC address of the network card when choosing an IPV6 Adress. Proof: http://www.youtube.com/watch?v=30CnqRK0GHE&NR=1 at 7:36 video time. If you want to be anonymous on the internet (so that nobody can find you when you download something, etc.) you need this EUI-64 to be bipassed in order for the MAC address not to be discovered by harmful third parties on the internet and for privacy. How do you avoid EUI-64 MAC address usage in IPV6 selection in Ubuntu? Also for DHCP IPV6?

• Can't connect to wireless without typing sudo modprobe b43 in terminal

  - by user90889

  I just upgraded to 12.04 on an old ACER Travelmate 5320 using Broadcom 4311. I wasn't able to connect to the internet through the wireless for a few days. It didn't even display wireless networks. I was finally able to make it work by following the instructions found here: http://linuxwireless.org/en/users/Drivers/b43#supported However, each time I log on to the computer I have to go to the terminal and type sudo modprobe b43 to make the wireless work. Is there somehow I can avoid this? I have used Ubuntu for many years but always relied on other people to help me with the technical stuff. The terminal is alien to me so I literally follow online forum instructions without knowing what I'm doing. Also, I tried many many things before I managed to make it work. So I'm worried I may have installed something that now conflicts with whatever the sudo modprobe b43 does. Thank you

• Remote Diagnostic Agent (RDA) version 4.30

  - by inowodwo

  posted by Maurice Bauhahn Remote Diagnostic Agent (RDA) version 4.30 was released on December 11th A free download can be accessed via Knowledge Management article 314422.1 and installed in any Enterprise Performance Management 11.1.2.x environment. EPM-specific instructions are available in Knowledge Management article 1304885.1. This RDA version incorporates two new modules (EAS=Essbase Administration Services; HWA=Hyperion Web Analysis) and improvements in modules and profiles relating to twelve other Hyperion applications (EPM, EPMA, ESS, FCM, HFM, HFR, HIR, HPL, HPSV, HSS, PR, and HSV). To follow best practice, run related RDA profiles [for example: "perl rda.pl -vnSCRPp Hyperion1112_EAS"] and attach the output zip file [by default in \rda\output\] to your service requests. The comprehensive set of details provided in such output files should help technicians to avoid delays in handling service requests (by avoiding ping-pong communications resulting from repeated requests for additional values).

• ACPI Events not triggered after booting

  - by user3208188

  I purchased a Convertible (Laptop and Tablet, Ubuntu 14.04 installed) and would like to execute a script when changing from laptop to tablet mode and the other way around. So I created two new files within the /etc/acpi/events folder corresponding to two new scripts in the /etc/acpi folder. Everything works well if I create a new acpid process (e.g "sudo acpid -c /etc/acpi/events -s /var/run/acpid.socket") manually. However, if I do not initiate this process manually the scripts are not executed, even though there is a process running with the same options right after the machine has booted by default. The only difference I can find is the parent pid. If I create the process the parent is "init --user", while the parent of the automatically initiated process is "/sbin/init". Can anyone help me by explaining why this issue happens and how I can avoid to start an acpid process manually every time I boot the device?

• Using mocks to set up object even if you will not be mocking any behavior or verifying any interaction with it?

  - by smp7d

  When building a unit test, is it appropriate to use a mocking tool to assist you in setting up an object even if you will not be mocking any behavior or verifying any interaction with that object? Here is a simple example in pseudo-code: //an object we actually want to mock Object someMockedObject = Mock(Object.class); EqualityChecker checker = new EqualityChecker(someMockedObject); //an object we are mocking only to avoid figuring out how to instantiate or //tying ourselves to some constructor that may be removed in the future ComplicatedObject someObjectThatIsHardToInstantiate = Mock(ComplicatedObject.class); //set the expectation on the mock When(someMockedObject).equals(someObjectThatIsHardToInstantiate).return(false); Assert(equalityChecker.check(someObjectThatIsHardToInstantiate)).isFalse(); //verify that the mock was interacted with properly Verify(someMockedObject).equals(someObjectThatIsHardToInstantiate).oneTime(); Is it appropriate to mock ComplicatedObject in this scenario?

• How can an application (like Firefox) be forced to use a certain network interface?

  - by Lekensteyn

  I've two interfaces: eth0 and wlan0 on a notebook. Possible use cases: eth0 grants me Internet access, and wlan0 is currently connected to a router which does not have Internet-connectivity. For development purposes, I need to connect to the wlan0 by default, but use eth0 for surfing eth0 and wlan0 are both connected to the Internet. For a torrent application, eth0 should be used for speed, but for portability of the notebook, SSH should have a connection over wlan0 eth0 is a wire connection, wlan0 is a wireless one. Sensible data should be transferred over eth0, but other traffic can go over wlan0 as well. Is there a way to force applications (like nc.traditional or firefox) to use a certain network interface? A wrapper like example-wrapper eth0 program is fine too if such program exist. It would be nice if it could configured within Firefox (in runtime). I'd like to avoid IPTables solutions if possible.

• Using a GPL licensed library in a commercial app

  - by user577616

  I develop an android application and in my app I use a libary (jar) that I download from the internet. This jar is open-source under the "GNU General Public License v2". I tried to read the text of the license but had difficulty understanding it. My question is: can I use this libary without changing nothing in the jar in a commercial application? I will be making profit from selling my app which uses this GPL-ed .jar file. If possible, I would like to avoid converting my application to open-source.

• How to ensure that a member variable is initialized before calling a class method

  - by Omkar Ekbote

  There's a class with a parametrized constructor that initializes a member variable. All public methods of the class then use this member variable to do something. I want to ensure that the caller always creates an object using the parametrized constructor (there is also a setter for this member variable) and then call that object's methods. In essence, it should be impossible for the caller to call any method without setting a value to the member variable (either by using the parametrized constructor or the setter). Currently, a caller can simply make an object using the default constructor and then call that object's method - I want to avoid checking whether or not the member variable is set in each and every one of the 20-odd methods of the class (and throw an exception if it is not). Though a runtime solution is acceptable (better than the one I mentioned above); a compile-time solution is preferable so that any developer will not be allowed to make that mistake and then waste hours debuggging it!

• Advice on what to learn? [closed]

  - by ICTech

  Currently I work as a .NET C# programmer, quite fresh faced at that (only been working professionally for 8 months) I'm enjoying what I'm doing, but I'm now thinking ahead for other languages to learn. I've heard from quite a few seasoned developers that they reckon it's worth getting in to HTML5. Before I asked this question I read a few of the other questions similar to this, but most were dated back a few years. I'm wondering what your advice would be to an aspiring programmer, what I should avoid going for (i.e. as I understand it Flash is essentially going to be phased out due to HTML5) I was looking in to WPF and the more updated .NET technologies, but someone advised me that WPF stuff will probably be redundant in the future. Thanks for your advice and opinions :)

• SEO problem for site with 2 domains [closed]

  - by Harry

  Possible Duplicate: What is duplicate content and how can I avoid being penalized for it on my site? I have two domains pointing to the same site. I want both domains to co-exist, they share most of the same content, but they differ in design and they are aimed at different markets / rivaling communities. Is there a way to let google know that these two domains are the same site and don't cause me to get hit with a duplicate content penalty? Any other general SEO tips for this situation would also be welcomed. Thanks. Come on man, why was this closed. The linked page is completely irrelevant for me.

• Failed to allocate memory - What is it trying to say?

  - by asprin

  In my early days of programming I often used to get memory related fatal errors in the following format: Fatal error: Allowed memory size of <some big number> bytes exhausted (tried to allocate <some small number> bytes) in /path/to/filename.php on line <some line number> I'm a little embarrassed to state that even though I have figured out how to solve them and take steps to avoid them altogether, I'm still not quite sure what exactly does the message translate to in simple words. For example, if I get a message such as: Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 4000 bytes) in ........ on line 34 As things stand at the moment, I assume it to be stating that the script consumes 67108864 bytes of data, but only 4000 bytes are available during runtime. Am I right in my assumption? If not, what's the correct interpretation?

• Joining and compressing all javascript files together - good idea?

  - by Tomáš Zato

  Curently, I avoid loading any unnecesary scripts on individual pages of my site. I have a class that remembers all javascript files that were requested during PHP processing and adds them to HTML. I was just thinking that I could merge the current set of files, save the result in special directory and let the browser download just one, big file. Since the number of possible combinations is not very high, I would end up with about 10 combined files for different pages. I've never seen that on any site. What are the reasons not to do it? I need very fast page load.

• Settings object with singleton pattern

  - by axis

  I need to build an object that will have only one instance because this Object is dedicated to the storage of vital settings for my application and I would like to avoid a misuse of this type or a conflict at run-time. The most popular solution for this, according to the internet, is the Singleton pattern. But I would like to know about other ideas or solutions for this; also I would like to know if other solutions can be much more easy to grasp for an user of this hypothetical library. Thanks.

• How do you usually manage callbacks in Java using Swing library?

  - by none

  I'm quite new to the Java Swing programming, and GUI development as well. As a beginner, I'm currently reading Design Pattern, but finding what I'm looking for is quite hard, most of the times. So far, I've never had huge problems defining a view hierarchy - I just use to subclass component from component. But the hard-to-do here is how managing callbacks, which often become hard to maintain due to the hard code. During my last projects, I tried to separate GUI, Listener and Callbacker objects which cooperated together, but in this way it was really hard adding new features. So, which kind of best patterns or best practices do you tend to use when trying to maintain, add new features or even worst avoid to hard-code classes which manage callbacks method in this kind of frameworks (mainly Java Swing)?

• Using Minified Page Specific JS [migrated]

  - by Mike C

  I've been working on a rather large scale project which makes use of a number of different pages with some very specific Javascript for each of them. To lessen load times, I plan to minify it all in to one file before deploying. The problem is this: how should I avoid launching page specific JS on pages which don't require it? So far my best solution has been to wrap each page in some additional container <div id='some_page'> ...everything else... </div> and I extended jQuery so I can do something like this: // If this element exists when the DOM is ready, execute the function $('#some_page').ready(function() { ... }); Which, while kind of cool, just rubs me the wrong way.

• Collapsible menu and amount of links in a web page

  - by dstonek

  One of my pages contain three levels of a collapsible menu (JS + CSS from mycssmenu.com). There are a dozen first level items displayed to users, each one with various second level items, and finally a lot of third level items, each one containing a related link. This generates a lot of internal links (300+). Because of SEO should I change the way the collapsible menu is displayed to reduce link amount? What do you suggest? I would like to avoid users to have to open a new page just to only see what are third level items and eventually follow one of its links.

• Are session aware Models a bad thing?

  - by kevtufc

  I'm thinking specifically in Rails here, but I suspect this is a wider question. In a Rails web application I'm using data from the session in models in order that the models know who is logged in. I use this in a method which filters out some data from the database depending on a very simple permissions system. The thing is: using sessions in models in Rails requires a bit of a workaround. It works, but I've a feeling that it's something that I shouldn't be doing and I'm worried there's a big gotcha I'm missing. I suppose the Right Thing To Do would be to return all the data and filter out the not-wanted bits in the controller before passing that to the view, but doing it in the model seems to avoid quite a bit of code duplication and so feels "cleaner." Can anyone tell me why or shouldn't do this? Or that it's not a problem?
