  • Top ten security tips for non-technical users

    - by Justin
    I'm giving a presentation later this week to the staff at the company where I work. The goal of the presentation is to serve as a refresher/remidner of good practices that can help keep our network secure. The audience is made up of both programmers and non-technical staff, so the presentation is geared for non-technical users. I want part of this presentation to be a top list of "tips". The list needs to be short (to encourage memory) and be specific and relevant to the user. I have the following five items so far: Never open an attachment you didn't expect Only download software from a trusted source, like download.com Do not distribute passwords when requested via phone or email Be wary of social engineering Do not store sensitive data on an FTP server I have two questions: Do you suggest any additional items? Do you suggest any changes to existing items?

  • Can't install libglib2.0-dev

    - by Joachim Pileborg
    Since Handbrake can't be installed in Oneiric, I decided to try and build it from source instead. The build is interrupted because it complains glib is not installed, so I thought I better install the glib development package. But I cant: $ sudo aptitude install -V libglib2.0-dev The following NEW packages will be installed: libglib2.0-dev{b} [2.30.0-0ubuntu4] 0 packages upgraded, 1 newly installed, 0 to remove and 0 not upgraded. Need to get 1 775 kB of archives. After unpacking 8 831 kB will be used. The following packages have unmet dependencies: libglib2.0-dev: Depends: libglib2.0-0 (= 2.30.0-0ubuntu4) but 2.31.0-0ubuntu1~oneiric1 is installed. Depends: libglib2.0-bin (= 2.30.0-0ubuntu4) but 2.31.0-0ubuntu1~oneiric1 is installed. Internal error: the solver Install(libglib2.0-bin 2.30.0-0ubuntu4 <libglib2.0-dev 2.30.0-0ubuntu4 -> {libglib2.0-bin 2.30.0-0ubuntu4 libglib2.0-bin 2.30.0-0ubuntu4}>) of a supposedly unresolved dependency is already installed in step 237 Aptitude the suggest a solution that involves removing basically all libraries, including libc. How do I install the glib development package?

  • Retrofit WebForms with ASP.NET MVC - NoVa Code Camp 2010.2 Demo

    - by Soe Tun
    Thank you to everyone who attended my Retrofit WebForms with ASP.NET MVC session at NoVa Code 2010.2. It was a fun event for me and I hope you had a great time and learned something from it. I wish I had more time to go over some more important topics in more detail. I *promise* I will be writing blog post series about it since I'll have some vacation time during the December holidays to cover some topics that I didn't get to cover in detail.   Please note that the ".bak" file included in the zip file is a SQL Server Database backup file. You have to restore it on your Database server to run it with the source code demo.   Please feel free to ask me about the demo project through Twitter or from this blog post. I'll be glad to help you out. If you want me to give this presentation at your .NET User Group, please let me know and I'll be honored to speak there also.   Again, thank you all and have a great holiday season. Here is the download link to my Demo project Zip file with the PowerPoint presentation in it. Please let me know if the link doesn't work.

  • What You Said: How You Organize a Messy Music Collection

    - by Jason Fitzpatrick
    Earlier this week we asked you to share your tips, tricks, and tools, for managing a messy music collection. Now we’re back to share so great reader tips; read on to find ways to tame your mountain of music. Several readers were, despite having tried various techniques over the years, fans of doing things largely the manual way. Aurora900 explains: I spent a weekend sorting everything myself once. Took a while, but now I have folders sorted by artist, and within the artist folders are folders for their albums. With my collection at about 260gb, it can be a daunting task, but it’s well worth it in the end. I don’t have the tagging issue as I make sure anything I have is properly tagged to begin with… If I’m ripping a CD I use Easy CD-DA Extractor, which automatically searches a database on the internet for the tags. If I’m downloading something, if its from a reputable source its going to be properly tagged already.

  • auspex LFS backups

    - by user1250465
    I have some backup tapes which existed on an AUSPEX file server. The backups were written to tape with the SunOs version of the CPIO command. Now that I need to restore them, (of course there are no more auspex servers in existance), the backups won't restore because the headers are not standard. I have dumped the tape images to disk. PAX, CPIO, and TAR cannot read the images. I've tried all of the CPIO format options. The errors I get are "name too long", "byte swapped in header", or just junk output. I can open up the images and read the contents of the files, but cannot restore the images. I have found that SunOs had a special header in CPIO V2.5 images. I have found the source for cpio, now I need definition of the SunOs header inside CPIO?

  • Moving a Drupal between linux servers, best practice to avoid file-ownership problems

    - by zero
    I want to port over a Drupal commons 6x24 from a local LAMP-stack to a production webserver. Both systems run OpenSuse Linux. How do I do this, what are the most important steps. How should I handle file-ownership. It's important for me to have to have full control of the file ownership. If I use the wwwrun account, I frequently run into problems, due to a very strict webserver-admin. See for example the long history of looking for fixes and solutions see this thread and even more interesting see this very long and impressive thread here. All troubles I run into have to do with file-owernship and permissions. This is my current setup; Note: This was just a quick hacked installation - quick and dirty. Well my interest is after the general options i have in the port of a drupal from linux to linux linux-vi17:/srv/www/htdocs/com624 # ls -l insgesamt 224 -rwxrwxrwx 1 root www 45285 19.

  • Project freezed - what should I leave to the people after me?

    - by Maistora
    So the project I've been working on is now going to be freezed for unknown period of time. May be when the project unfreezes it won't be assigned to me or anybody of the current team. Actually we did also inherit the project after it had been freezed but there was nothing left by the team before us to help us understand even the basic needs of the project, so plenty of time passed by until we got to know the project well. My question is what do you think we should do to help people after us to best understand the needs of the project, what we have done, why we've done it, etc. I am open to other ideas of why should we leave some tracks to the others that will work on this project also. Some steps we already have taken: technical documentation (not full but at least there is some); source-control system history; estimations on which parts of the project need improvement and why we think so; bunch of unit tests. What do you think of what we've already prepared and what else could we do?

  • Sound problems in Windows 7

    - by Plastkort
    hi! I hope I reached the correct forum for this question. I have a media computer with a third party audio card (Soundblaster audigy SE) I use a coaxial digital audio cable connected to a Onkyo TX SR508. if I use normal audio, the sound seems very low, I have to set volume atleast to 62 in my amplifier to hear anything, however if I set digital SPDIF I have no means of controlling the audio volume from the PC (only from the amplifier) and this can be nasty if I toggle between movies that uses Digital AC3/THX and movies wihtouth, if I look at movies capable of AC3 the volume gets VERY loud if amp is set to 62, 32 is more than enough volume when using passthrough. so this bothers me is how can I get the same amount of volume with or without digital output? I tried also other soundcards, internal red light Digital audio cable... if I connect to my television I get ok sound on any sound source via HDMI... help :)

  • erratic audio levels on windows vista

    - by old retired dude
    I'm somewhat hard of hearing. I've been listening to my windows Vista machine with a pair of headphones so I don't annoy the others. I have 2 issues: 1) the volume varies enormously depending on the source. Having a windows alert occur while I am listening to a DVD or Youtube is a painful experience. Is there a preferred way to set all the different audio controls so I have a more constant volume? I already have lowered the volumes of the windows alerts. 2)Is there a way to limit the volume of my headphones to protect what is left of my hearing? Is there a software solution or should I be going for a hardware limiter? thanks retired dude

  • Update to SQL Server Configuration Scripting Utility

    - by Bill Graziano
    Last spring I released a utility to script SQL Server configuration information on CodePlex.  I’ve been making small changes in this application as my needs have changed.  The application is a .NET 2.0 console application.  This utility serves two needs for me.  First it helps with disaster recovery.  All server level objects (logins, jobs, linked servers, audits) are scripted to a single file per object type.  This enables the scripts to be easily run against a DR server.  If these are checked into source control you can view the history of the script and find out what changed and when. The second goal is to capture what changed inside a database.  Objects inside a database (tables, stored procedures, views, etc.) are each scripted to their own file.  This makes it easier to track the changes to an object over time.  This does include permissions and role membership so you can capture security changes.  My assumption is that a database backup is the primary method of disaster recovery for databases so this utility is designed to capture changes to objects.  You can find the full list of changes from the original on the Downloads page on CodePlex.

  • Gmail flagging emails as spam despite SPF being enabled and working perfectly

    - by Asif
    I have a website where people can recommend contents to their friends using their email. The issue is that emails are being flagged as spam whereas if I do the same from my development machine things are working out fine. I have enabled SPF and it is perfect. When sending through website, the email appears as this in Gmail Inbox: From [email protected] to [email protected]. When I send it from my development machine it appears as : From xyz.com via mywebsite.com to [email protected] mailed by mywebsite.com and this is exactly how I envisioned it. From what little I could figure out by looking at the source of emails in Gmail is that when sending from my development machine Gmail correctly recognizes my domain as mywebsite.com for which SPF is enabled and hence it treats it as genuine email. Whereas Gmail recognizes my domain as [email protected] when sent through the website. Can someone tell me why it does so? Any help would be really appreciated.

  • Port forwarding on D-Link DIR-615 super-slow, useless

    - by Jaroslav Záruba
    Hello I have replaced my old router with DIR-615 from D-Link, and now the port forwarding is so slow it makes the router practically useless. Accessing the router itself (admin UI) is without issues, no delay whatsoever. But when I try to access a service on another computer in the network the requests take minutes and minutes. (E.g. I can see source of my GWT-app main page, but loading additional CSS and JS files takes years.) If anyone could recommend any further diagnostics I should do to figure out what is happening it would be great. Few notes: happens with more services (web-app on Tomcat, viewing directory index via Apache) it does not make a difference whether the service is hosted on wired or wireless PC accessing the service on a localhost works fine turning off firewall on the target PC does not make difference either (makes sense) when I replace this router with the old one (both 192.168.1.1) everything works fine I see nothing suspicious in the router's log I believe I have the latest firmware (4.11) DIR-615 sucks, it already died once completely Regards Jarda Z.

  • Enable live streaming on website

    - by Somebody
    I have a server colocated in a datacentre (dedicated 1Gbit line, SSDs, etc.) running CentOS 5.4 64-bit. I want to stream live video from a device (webcam, camcorder, whatever.) to my server which inturn can re-broadcast it on demand through a flash player (such as Flowplayer) so that more users will be able to watch the stream since the server is quite fast. Does a solution like this exist already (streaming software from live source to flash media server) or will I need to hire someone to code it? I see that VLC has an option to stream video.. will that be suitable in this case? Or is there a better way to do it? I don't want a browser based solution on my end. It'll be great if this can be done without running an X server but I don't mind either way. This will be running on a dedicated PC at home.

  • How do you configure ISC Bind to support GSS-TSIG Updates?

    - by netlinxman
    First, has anyone EVER configured ISC bind 9.5.0 OR greater with support for GSS-TSIG Dynamic DNS Updates AND gotten it to work? If so, what is the configuration that was used to make that happen? I feel close to having this working. I see that GSS cred passes w/o apparent error during the TKEY negotiation with an Active Directory DC and the BIND DNS server: client 192.168.0.30#52314: query gss cred: "DNS/[email protected]", GSS_C_ACCEPT, 4294967256 gss-api source name (accept) is [email protected] process_gsstkey(): dns_tsigerror_noerror client 192.168.0.30#52314: send But, when the Update is sent, it is refused: client 192.168.0.30#58330: update client 192.168.0.30#58330: updating zone 'example.com/IN': update failed: rejected by secure update (REFUSED) client 192.168.0.30#58330: send Does anyone have this working in the real world?

  • Are less domains better than more domains in active directory?

    - by johnny
    A colleague of mine wants to add a domain to our forest. He said it would be good for security. I believe him but I have no idea why it is any better than with just one domain. I read this on Wikipedia but it has no source: "Microsoft recommends as few domains as possible in Active Directory and a reliance on OUs to produce structure and improve the implementation of policies and administration." I have no idea if it's right or not. I was hoping for comments. Thank you.

  • Apache virtual hosts - Resources on website not loaded when accessed from other hostname than localhost

    - by Christian Stadegaart
    Running virtual hosts on Mac OS X 10.6.8 running Apache 2.2.22. /etc/hosts is as follows: 127.0.0.1 localhost 3dweergave studio-12.fritz.box 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost Virtual hosts configuration: NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot "/opt/local/www/3dweergave" ServerName 3dweergave ErrorLog "logs/3dweergave-error_log" CustomLog "logs/3dweergave-access_log" common <Directory "/opt/local/www/3dweergave"> Options Indexes FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory> </VirtualHost> <VirtualHost *:80> ServerName main </VirtualHost> This will output the following settings: *:80 is a NameVirtualHost default server 3dweergave (/opt/local/apache2/conf/extra/httpd-vhosts.conf:21) port 80 namevhost 3dweergave (/opt/local/apache2/conf/extra/httpd-vhosts.conf:21) port 80 namevhost main (/opt/local/apache2/conf/extra/httpd-vhosts.conf:34) I made 3dweergave the default server by putting it first in the list. This will cause all undefined virtual hosts' names to load 3dweergave, and thus http://localhost will point to 3dweergave. Of course, normally, the first in the list is the virtual host main and localhost will point to main, but for testing purposes I switched them. When I navigate to http://localhost, my CakePHP default homepage shows as expected: Screenshot 1 But when I navigate to http://3dweergave, my CakePHP default homepage doesn't show as expected. It looks like every relative link to resources are not accepted by the server: Screenshot 2 For example, the CSS isn't loaded. When I open the source and click on the link, it opens the CSS file in the browser without errors. But when I run FireBug while loading the webpage, it seems that the CSS file isn't retrieved. (<link rel="stylesheet" type="text/css" href="/css/cake.generic.css" />) How can I fix this unwanted behaviour?

  • Dynamically load images inside jar

    - by Rahat Ahmed
    I'm using Slick2d for a game, and while it runs fine in Eclipse, i'm trying to figure out how to make it work when exported to a runnable .jar. I have it set up to where I load every image located in the res/ directory. Here's the code /** * Loads all .png images located in source folders. * @throws SlickException */ public static void init() throws SlickException { loadedImages = new HashMap<>(); try { URI uri = new URI(ResourceLoader.getResource("res").toString()); File[] files = new File(uri).listFiles(new FilenameFilter(){ @Override public boolean accept(File dir, String name) { if(name.endsWith(".png")) return true; return false; } }); System.out.println("Naming filenames now."); for(File f:files) { System.out.println(f.getName()); FileInputStream fis = new FileInputStream(f); Image image = new Image(fis, f.getName(), false); loadedImages.put(f.getName(), image); } } catch (URISyntaxException | FileNotFoundException e) { System.err.println("UNABLE TO LOAD IMAGES FROM RES FOLDER!"); e.printStackTrace(); } font = new AngelCodeFont("res/bitmapfont.fnt",Art.get("bitmapfont.png")); } Now the obvious problem is the line URI uri = new URI(ResourceLoader.getResource("res").toString()); If I pack the res folder into the .jar there will not be a res folder on the filesystem. How can I iterate through all the images in the compiled .jar itself, or what is a better system to automatically load all images?

  • Understanding Asynchronous Programming with .NET Reflector

    - by Nick Harrison
    When trying to understand and learn the .NET framework, there is no substitute for being able to see what is going on behind at the scenes inside even the most confusing assemblies, and .NET Reflector makes this possible. Personally, I never fully understood connection pooling until I was able to poke around in key classes in the System.Data assembly. All of a sudden, integrating with third party components was much simpler, even without vendor documentation!With a team devoted to developing and extending Reflector, Red Gate have made it possible for us to step into and actually debug assemblies such as System.Data as though the source code was part of our solution. This maybe doesn’t sound like much, but it dramatically improves the way you can relate to and understand code that isn’t your own.Now that Microsoft has officially launched Visual Studio 2012, Reflector is also fully integrated with the new IDE, and supports the most complex language feature currently at our command: Asynchronous processing.Without understanding what is going on behind the scenes in the .NET Framework, it is difficult to appreciate what asynchronocity actually bring to the table and, without Reflector, we would never know the Arthur C. Clarke Magicthat the compiler does on our behalf.Join me as we explore the new asynchronous processing model, as well as review the often misunderstood and underappreciated yield keyword (you’ll see the connection when we dive into how the CLR handles async).Read more here

  • How to use mount points in MilkShape models?

    - by vividos
    I have bought the Warriors & Commoners model pack from Frogames and the pack contains (among other formats) two animated models and several non-animated objects (axe, shield, pilosities, etc.) in MilkShape3D format. I looked at the official "MilkShape 3D Viewer v2.0" (msViewer2.zip at http://www.chumba.ch/chumbalum-soft/ms3d/download.html) source code and implemented loading the model, calculating the joint matrices and everything looks fine. In the model there are several joints that are designated as the "mount points" for the static objects like axe and shield. I now want to "put" the axe into the hand of the animated model, and I couldn't quite figure out how. I put the animated vertices in a VBO that gets updated every frame (I know I should do this with a shader, but I didn't have time to do this yet). I put the static vertices in another VBO that I want to keep static and not updated every frame. I now tried to render the animated vertices first, then use the joint matrix for the "mount joint" to calculate the location of the static object. I tried many things, and what about seems to be right is to transpose the joint matrix, then use glMatrixMult() to transform the modelview matrix. For some objects like the axe this is working, but not for others, e.g. the pilosities. Now my question: How is this generally implemented when using bone/joint models, and especially with MilkShape3D models? Am I on the right track?

  • c++ How to use angular velocity that derived from inertia and force(torque) in 3d

    - by user1217203
    I am relatively new to game development. May my terminology and description are not appropriate. Please excuse my poor phrasing and help me by giving advice on how to question better if this question seems less fitting. I really appreciate your efforts. Hi. I am having hard time interpreting the set of values I have. I have inertia and force(torque) in terms of x y z. FYI I used x and y coordinates as my ground, flat coordinates and z as my up/down. I am assuming that since f = ma, that angular acceleration must be a = f / m. So I divide my torque by inertia. Then I add those x y z values to my angular velocity variable's x y z. However these x y z values confuse me. Don't I need angle/sec or radian/sec sort of values in order to apply rotation? The x y z values I have seemed to not say anything about radians or angular movement. Question : If I have ( 1, 2, 3 ) or any ( x, y, z ) as my angular velocity, how do I actually apply it as angular movement? FYI Here I am pasting my code : float mass = 100; float devidedMass = 1.0/12 * mass; Vec3 innertia( devidedMass* (_box._size.z*_box._size.z + _box._size.x*_box._size.x), devidedMass* (_box._size.y*_box._size.y + _box._size.x*_box._size.x), devidedMass* (_box._size.y*_box._size.y + _box._size.z*_box._size.z )); box._angAccel += forceAng/innertia; box._angVelo += box._angAccel; box._angAccel.allZero(); source of my inertia calculation http://www.health.uottawa.ca/biomech/courses/apa4311/solids.pdf

  • Speed up file access on home network

    - by kurasa
    I have 2 PCs (Windows 7 Ultimate) and a Mac running Windows 7 using vmware fusion on my home network tied together using WRN1000 NETGEAR Router On one of the PC's I have a set of file (MYOB .myo). These use a data source to access the data in the files. Operations (reading,writing) to the .myo on the PC which hosts the files is fine but the other 2 it is painfully slow/unreliable and I am wondering what I can do to speed this up. Some ideas I have are 1. Turn off the Windows firewall on all the windows installations on the home network 2. Buy another router. Specifically a router which I can connect a USB flash drive on the back where I can put the .myo files and all the PC can access the files from the USB flash drive on the router (does this speed things up?) Any advice greatly appreciated on how I can speed up this access to data
