  • How long do uploaded files stay in the tmp folder in Linux Ubuntu?

    - by Jean-Nicolas Boulay Desjardins
    I am building a web application where my users will be able to upload files. After the files are uploaded I need to send the files to two other servers, and after they will be deleted from the server where they were just uploaded to. I am wandering is it a good I idea to keep the uploaded files in the tmp/ folder the time the uploaded files are sent to the other two servers or should I move them to another folder incase they get deleted? I am also wandering because I would like to know if I have to build a cron script to get rid of the files that have been transfered to the other servers so that I get my disk space back.

  • How can I protect files on my NGiNX server?

    - by Jean-Nicolas Boulay Desjardins
    I am trying to protect files on my server (multiple types), with NGiNX and PHP. Basically I want people to have to sign in to the website if they want to access those static files like images. DropBox does it very well. Where by they force you to sign in to access any static files you put on there server. I though about using NGiNX Perl Module. And I would write a perl script that would check the session to see if the user was sign in to give them access to a static file. I would prefer using PHP because all my code is running under PHP and I am not sure how to check a session created by PHP with PERL. So basically my question is: How can I protect static files of any types that would need the user to have sign in and have a valid session created with a PHP script?

  • How to install a proxy LDAP

    - by Jean-Claude
    I have to install an LDAP proxy on a compute cluster frontend. The idea is to avoid the compute nodes to make too many requests on the campus LDAP server. How can I install this to make it work with the school's LDAP? The frontend OS is a RHEL 6.2. I found that I have to install the LDAP server and configure it as a proxy. But all I can find is examples of /etc/openldap/slapd.conf file configuration but after testing different configuration, no results. Furthermore, according to RHEL 6 - Deployment Guide, this config file is obsolete: OpenLDAP no longer reads its configuration from the /etc/openldap/slapd.conf file. Instead, it uses a configuration database located in the /etc/openldap/slapd.d/ directory. Any help is welcomed. Thank you

  • bootmgr is missing on Toshiba laptop with Windows 7

    - by jean
    I have a Toshiba laptop with Windows 7 on it. As soon as I turn my computer on it says bootmgr is missing The only thing I can get into is the setup menu. Does anyone know what might be wrong? My step brother thinks that it might be that everything was erased off my hard drive. The last thing he did when he used it was to perform the Toshiba updates and restart the computer. If anyone knows what might be wrong or how I could get my computer up and running please let me know.

  • SharePoint: Can't Connect to a Configuration Database When Using Configuration Wizard

    - by Denis
    Hello everyone. I wonder if you could help me with the following problem: We have a SharePoint farm consisted of two servers with an NLB (a load balancer), a database server and an index server (4 servers in total). The issues initially appeared when we were trying to change Search settings via Shared services provider and an error was appearing with the message I can’t even remember now. To fix that problem, we decided to restart Search services on the Index server via Central Administration… and the process had stuck with a status “stopping” for several days. We’ve found a few solutions on the forums, but nothing had helped. Then we’ve tried to exclude the Index server from the farm, but yet again, Search services would not stop. However, after a week we’ve noticed that the services finally stopped. That was a prologue. So, after the Search services have finally stopped, we decided to return the Index server back to the farm via the SharePoint Configuration wizard. When we click on a button “Search database instances” (don’t know the exact name in English, we have a Russian version), a correct database name and user are automatically appear in the relevant fields. Then we supply a password for the user and click “next” two times and the configuration begins. Unfortunately, at the second stage we receive the error “Could not connect to a configuration database” with the exception in the log file: “Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.” Now we can’t figure out why the configuration wizard can’t connect to the configuration database. Any suggestions will be really appreciated.

  • Paperclip and xhr.sendAsBinary

    - by Denis
    Hi, I use paperclip to add a file to my model. I want to use the new feature of firefox 3.6, xhr.sendAsBinary, to send a file with an ajax request. Here is how I build my request : var xhr = new XMLHttpRequest(); xhr.open("POST", "/photos?authenticity_token=" + token + "&photo[name]=" + img.name + "&photo[size]=" + img.size); xhr.overrideMimeType('text/plain; charset=x-user-defined-binary'); xhr.sendAsBinary(bin); name and size are saved in my model without problem but the file itself is not catched by paperclip. my model class Photo < ActiveRecord::Base has_attached_file :photo, :styles => { :medium => "300x300>", :thumb => "100x100>" } end the migration def self.up add_column :photos, :photo_file_name, :string add_column :photos, :photo_content_type, :string add_column :photos, :photo_file_size, :integer add_column :photos, :photo_updated_at, :datetime end and my controller # POST /photos # POST /photos.xml def create @photo = Photo.new(params[:photo]) respond_to do |format| if @photo.save format.html { redirect_to(@photo, :notice => 'Photo was successfully created.') } format.xml { render :xml => @photo, :status => :created, :location => @photo } else format.html { render :action => "new" } format.xml { render :xml => @photo.errors, :status => :unprocessable_entity } end end end Any idea how to solve this issue?

  • Issues with ACTION_HEADSET_PLUG broadcast in Android

    - by Denis M
    I've tried these phones: Moto Backflip 1.5, Nexus One 2.1 Basically I register BroadcastReceiver to get ACTION_HEADSET_PLUG broadcast and look on 3 extras that come in intent: state name microphone Here is the description from API: * state - 0 for unplugged, 1 for plugged. * name - Headset type, human readable string * microphone - 1 if headset has a microphone, 0 otherwise Issue #1: Broadcast comes when activity is started (not expected), when screen rotation happens (not expected) and when headset/headphones plugged/unplugged (expected). Issue #2: Backflip phone sends null for state + microphone, 'No Device' as name when headset/headphones unplugged, and sends null for state + microphone, 'Stereo HeadSet'/'Stereo HeadPhones' as name when headset/headphones plugged. Nexus even worse, it always sends null for state + microphone, 'Headset' as name when headset/headphones plugged or unplugged. Question: How it can be explained that API is broken so much on both 1.5 and 2.1 versions and different devices, manufactures?

  • Matplotlib subplots_adjust hspace so titles and xlabels don't overlap ?

    - by Denis
    With say 3 rows of subplots in matplotlib, xlabels of one row can overlap the title of the next; one has to fiddle with pl.subplots_adjust( hspace ), annoying. Is there a recipe for hspace that prevents overlaps and works for any nrow ? """ matplotlib xlabels overlap titles ? """ import sys import numpy as np import pylab as pl nrow = 3 hspace = .4 # of plot height, titles and xlabels both fall within this ?? exec "\n".join( sys.argv[1:] ) # nrow= ... y = np.arange(10) pl.subplots_adjust( hspace=hspace ) for jrow in range( 1, nrow+1 ): pl.subplot( nrow, 1, jrow ) pl.plot( y**jrow ) pl.title( 5 * ("title %d " % jrow) ) pl.xlabel( 5 * ("xlabel %d " % jrow) ) pl.show() My versions: matplotlib 0.99.1.1, python 2.6.4, Mac osx 10.4.11, backend: Qt4Agg (TkAgg = Exception in Tkinter callback) (For many extra points, can anyone outline how matplotlib's packer / spacer works, along the lines of chapter 17 "the packer" in the Tcl/Tk book ?)

  • Decrypting “long” message encrypted with RSA java

    - by Denis
    Hi this is the same question, that was asked two years ago: Java/JCE: Decrypting “long” message encrypted with RSA I had a large byte array and rsa keypair, initiated by value 1024. Using rsa encryption and the specified size of the key is strong requirement, I can't change it. So I can't use symmetric encryption with asymetric encryption symmetric key. I can't use any other keys. I had a byte array and need ciphered byte array to be returned. I wonder if there is any ready tool, that can manage with this problem? Sorry for such an amateurish question, but I really need a help.

  • How to configure web proxy for Jing

    - by Denis
    Jing is great. But it won't start unless it can phone the mother ship. My internet access is via corporate web proxy. Jing doesn't seem to offer any way of configuring its connection to the internet. You'd think it would just use the windows internet connection settings that work for browsing, but no dice. Anyone solve this problem? Maybe there are some configuration files or registry settings that would fix this? Thanks!

  • iPhone autorotation for too many objects on screen

    - by Denis
    Hi! I have a BlahAppDelegate, BlahViewController and no nibs in my iPhone app project. Only some subclasses of UIView in addition. All this is situated in main.m. My app has 6 subclassed UIViews. Each of it contains 18 UIImageViews. I need to get autorotating work. Or custom rotating. Or something. For example it would be nice to fade the screen out when device is rotated, then move/resize views and then fade screen out. But I don't know how to automate it, without writing a resizing code for each of objects. Please help me if you can.

  • What are the benefits of using Boost.Phoenix?

    - by Denis Shevchenko
    Hello all! I can not understand what the real benefits of using Boost.Phoenix. When I use it with Boost.Spirit grammars, it's really useful: double_[ boost::phoenix::push_back( boost::phoenix::ref( v ), _1 ) ] When I use it for lambda functions, it's also useful and elegant: boost::range::for_each( my_string, if_ ( '\\' == arg1 ) [ arg1 = '/' ] ); But what are the benefits of everything else in this library? The documentation says: "Functors everywhere". I don't understand what is the good of it?

  • Big datastructures in functional programming

    - by Denis Gorodetskiy
    I'm newbie in Functional Programming. I have a huge neural network with thousands of neurons and every connection between neurons has its weight. I have to update these weights very often, several thousand times per learning session. Is FP still applicable here? I mean in fp we can't modify variables and only able to return new variables not changing previous values. Does this mean I have to recreate whole network on every weight update?

  • IDN aware tools to encode/decode human readable IRI to/from valid URI

    - by Denis Otkidach
    Let's assume a user enter address of some resource and we need to translate it to: <a href="valid URI here">human readable form</a> HTML4 specification refers to RFC 3986 which allows only ASCII alphanumeric characters and dash in host part and all non-ASCII character in other parts should be percent-encoded. That's what I want to put in href attribute to make link working properly in all browsers. IDN should be encoded with Punycode. HTML5 draft refers to RFC 3987 which also allows percent-encoded unicode characters in host part and a large subset of unicode in both host and other parts without encoding them. User may enter address in any of these forms. To provide human readable form of it I need to decode all printable characters. Note that some parts of address might not correspond to valid UTF-8 sequences, usually when target site uses some other character encoding. An example of what I'd like to get: <a href="http://xn--80aswg.xn--p1ai/%D0%BF%D1%83%D1%82%D1%8C?%D0%B7%D0%B0%D0%BF%D1%80%D0%BE%D1%81"> http://????.??/???????????</a> Are there any tools to solve these tasks? I'm especially interested in libraries for Python and JavaScript.
