  • Integrate code generation with eclipse c++ build

    - by Dan
    Hi, I am using Eclipse for C++ development on windows. I have also written a code generator that take an xml file and produces several C++ files. The project I am working on is currently setup to use the internal builder. What I would like to do is to run the code generator as part of the build process. My problem is that I haven't been able to find a way to make Eclipse identify that the files are present (or have been updated) without 'Refeshing' the project. So although I can run the code generator as a pre-build step, the files generated aren't guaranteed to be included in the build. Does anybody know whether there is a way to make Eclipse do a refresh after the pre-build step or something to that effect, using the internal builder? Thanks

  • open encrypted file with php

    - by stormdrain
    Hi, I'm looking for a way to open encrypted files that are stored on a server. I'm using mcrypt to encrypt the files. I was initially going to create a class that would open the file, decrypt it, write it to a new location, then open that. But I have convinced myself there is a better way (I just don't know what it is). It seems like there should be a way to stream it (?) to the browser once it's decrypted. The initial setup would just link to the file location and the browser would take over (e.g. .pdf files would bring up a dialogue offering to open or save the file). If possible, I'd like it to do the same after decoding. Pointers? Advice? Bueller? Thanks!

  • Linux filesystem with inodes close on the disk

    - by pts
    I'd like to make the ls -laR /media/myfs on Linux as fast as possible. I'll have 1 million files on the filesystem, 2TB of total file size, and some directories containing as much as 10000 files. Which filesystem should I use and how should I configure it? As far as I understand, the reason why ls -laR is slow because it has to stat(2) each inode (i.e. 1 million stat(2)s), and since inodes are distributed randomly on the disk, each stat(2) needs one disk seek. Here are some solutions I had in mind, none of which I am satisfied with: Create the filesystem on an SSD, because the seek operations on SSDs are fast. This wouldn't work, because a 2TB SSD doesn't exist, or it's prohibitively expensive. Create a filesystem which spans on two block devices: an SSD and a disk; the disk contains file data, and the SSD contains all the metadata (including directory entries, inodes and POSIX extended attributes). Is there a filesystem which supports this? Would it survive a system crash (power outage)? Use find /media/myfs on ext2, ext3 or ext4, instead of ls -laR /media/myfs, because the former can the advantage of the d_type field (see in the getdents(2) man page), so it doesn't have to stat. Unfortunately, this doesn't meet my requirements, because I need all file sizes as well, which find /media/myfs doesn't print. Use a filesystem, such as VFAT, which stores inodes in the directory entries. I'd love this one, but VFAT is not reliable and flexible enough for me, and I don't know of any other filesystem which does that. Do you? Of course, storing inodes in the directory entries wouldn't work for files with a link count more than 1, but that's not a problem since I have only a few dozen such files in my use case. Adjust some settings in /proc or sysctl so that inodes are locked to system memory forever. This would not speed up the first ls -laR /media/myfs, but it would make all subsequent invocations amazingly fast. How can I do this? I don't like this idea, because it doesn't speed up the first invocation, which currently takes 30 minutes. Also I'd like to lock the POSIX extended attributes in memory as well. What do I have to do for that? Use a filesystem which has an online defragmentation tool, which can be instructed to relocate inodes to the the beginning of the block device. Once the relocation is done, I can run dd if=/dev/sdb of=/dev/null bs=1M count=256 to get the beginning of the block device fetched to the kernel in-memory cache without seeking, and then the stat(2) operations would be fast, because they read from the cache. Is there a way to lock those inodes and/or blocks into memory once they have been read? Which filesystem has such a defragmentation tool?

  • Web App fails when moved to production environment. Which server permissions do I need?

    - by Ashley Ward
    I have developed a small web app. This app allows users to upload images. It also produces text files with the names of those images (the names are stored and retrieved to/from an MySQL Database.) I have developed this app using MAMP. To create the uploaded image files I use the PHP function imagejpeg('my/path/name.jpg') and to delete the files I use the PHP function unlink('folder1/folder2/name.jpg') to write to the text document I am using the function fopen('folder1/folder2/name.txt', 'w') all three of these functions produce errors related to permissions - now the site has been moved to a live hosting environment. Why is this? and what permissions do I need to set the folder's folder1 and folder2 to? I know that permission 777 is generally bad because it opens up your server to the public. However what I have found is that the functions fail to work unless I use 777 on the folders. Can anyone shed any light on my dilemma?

  • My Ruby Code: How can I improve? (Java to Ruby guy)

    - by steve
    Greetings, I get the feeling that I'm using ruby in an ugly way and possibly missing out on tonnes of useful features. I was wondering if anyone could point out a cleaner better way to write my code which is pasted here. The code itself simply scrapes some data from yelp and processes it into a json format. The reason I'm not using hash.to_json is because it throws some sort of stack error which I can only assume is due to the hash being too large (It's not particularly large). Response object = a hash text = the output which saves to file Anyways guidance appreciated. def mineLocation client = Yelp::Client.new request = Yelp::Review::Request::GeoPoint.new(:latitude=>13.3125,:longitude => -6.2468,:yws_id => 'nicetry') response = client.search(request) response['businesses'].length.times do |businessEntry| text ="" response['businesses'][businessEntry].each { |key, value| if value.class == Array value.length.times { |arrayEntry| text+= "\"#{key}\":[" value[arrayEntry].each { |arrayKey,arrayValue| text+= "{\"#{arrayKey}\":\"#{arrayValue}\"}," } text+="]" } else text+="\"#{arrayKey}\":\"#{arrayValue}\"," end } end end

  • Configuring sendmail to forward mail for a specific domain to a specific mail server without using M

    - by aHunter
    I am new to sendmail and would like to configure sendmail to forward all mail for a specific email address to another internal mail server. I need it to ignore the MX records and only send it to the server I specify but am not sure which files to edit or how to configure the sendmail config. Is it sufficient to add the server to the /etc/hosts and the /etc/mail/local-host-names files? Thanks in advance.

  • Can Linux play HDMI 1.4a 3D stereoscopic content?

    - by SofaKng
    I'm aware that there are no Bluray players for Linux but I'm wondering if it's possible to play Full 3D HD (1080p, Side-By-Side) MKV files (or Bluray BDMV folders, etc). Full 3D HD files are actually two 1080p frames "side-by-side" so the effective resolution is 3840x1200. In order to play these properly the software needs to switch to TV into 3D mode (or however HDMI 1.4a works). I don't think simply playing the 3840x1200 resolution file will work so are there any options out there?

  • Growable data structure in MATLAB

    - by rlbond
    I need to create a queue in matlab that holds structs which are very large. I don't know how large this queue will get. Matlab doesn't have linked lists, and I'm worried that repeated allocation and copying is really going to slow down this code which must be run thousands of times. I need some sort of way to use a growable data structure. I've found a couple of entries for linked lists in the matlab help but I can't understand what's going on. Can someone help me with this problem?

  • StreamWriter stops writing when file is opened from web link

    - by fearofawhackplanet
    Following on from my previous question... The following code creates log files on a web server: private void LogMessage(Message msg) { using (StreamWriter sw = File.AppendText(_logDirectory + DateTime.Now.ToString("yyyyMMddHH") + ".txt")) { sw.WriteLine(msg.ToString()); } } The log files are linked to from an admin page on the web site: foreach (FileInfo file in logDir.GetFiles()) { Response.Write("<a href='http:// .... /Logs/" + file.Name + "'>" + file.Name + "</a>"); } I'm getting the problem that after someone looks at one of the log files from the link, that log file stops being written to.

  • Creating managed file transfer software in java

    - by Shekhar
    Hello, I have been asked to do some POC on how we can provide a software solution which will be able to manage files. Manage files means it will be able to move files from source to destination servers. The client gave us 4 page document detailing what sort of software they are looking for. They dont want to use existing commercial softwares. They want to build their own customizable software. Has anybody worked on this type of project? Please provide your inputs on how should i approach this project. The software should be platform independent and should be built in java.

  • array_merge vs array_value for resetting array index

    - by Jamex
    I have 1 array that I want to re-index. I have found that both array_values and array_merge functions can do the job (and I don't need 2 arrays for the array_merge function to work). Which is faster for a very large array? I would benchmark this, but I don't know how and don't have the large array yet. Before re-index: Array ( [0] => AB [4] => EA [6] => FA [9] => DA [10] => AF ) After re-index: Array ( [0] => AB [1] => EA [2] => FA [3] => DA [4] => AF )

  • Old solutions being recalled in VisualStudio

    - by user1437135
    I have an odd scenario that I can't figure out, and would appreciate any advice offered. I'm running VisualStudio 2010 pro. I have a web application solution with 6 projects. On one occasion I opened up some files from a number of backup solutions to look at some historic code. I viewed them and closed the files. I did this with my current project open. I may have rebuilt the solution with them open but I'm not sure. I recently did a 'find', searching the whole solution, and noticed that the files from the backups are referenced as being part of the solution. How do I remove them?

  • What format is "undf"?

    - by ZlateWay
    By accident, I recently removed some videos from my phone. I tried to restoring them with Recuva and TuneUp Utilities and the results were "undf" files. I tried to open with VLC, Media Player Classic and other video players to no avail. Where/how do I find out the codec for these files? I would really love to be able to watch these videos again.

  • how can I send messages to/from a Websphere Message Broker from an embedded C client (no JVM)?

    - by queBurro
    What are my options for pubsubing (or point to point but pubsub is better) messages to and from an IBM message broker from an embedded headless C/C++ linux client that doesn't have a JVM? Ideally we want large file transfer (2GB once per day off of the client) encryption (SSL) reliable ('assured' delivery / QoS2, maybe QoS1 would do) The client in question currently only has exes and some bash scripts, I've been playing with MQTTv3 and RSMB, but for that I'd have to chomp the large files up (and reassemble back home) and I don't want to get into that if there's a transport that will do this for me? I've looked at MQTTv5 (but our client's got no JVM); JMS (no JVM) and XMS? which again looks like it gives me a C API but then needs the JVM to be installed on the client (or am I wrong?) any clues or hints would be appreciated, cheers

  • Does gunzip work in memory or does it write to disk?

    - by Ryan Detzel
    We have our log files gzipped to save space. Normally we keep them compressed and just do gunzip -c file.gz | grep 'test' to find important information but we're wondering if it's quicker to keep the files uncompressed and then do the grep. cat file | grep 'test' There has been some discussions about how gzip works if it would make sense that if it reads it into memory and unzips then the first one would be faster but if it doesn't then the second one would be faster. Does anyone know how gzip uncompresses data?
