• SQL Server Migration Assistant for Oracle problem

  - by Paul

  I've recently installed SSMA on my computer and after connecting to both the Oracle instance (which holds the database to be converted) and the SQL Server. I've mapped the needed schemas from oracle to mssql. The problem is that when i click on the report button for the assessment report there's an error popping up: Assesment Error : Nothing to Process The output window states: Starting conversion... Analyzing metadata... Conversion finished with 0 errors, 0 warnings, and 0 informational messages. There is nothing to process. Has anyone got experience with SSMA. I can't figure out what I am doing wrong. Thank you.

• Hiera concatenated lookup from yaml

  - by Brian

  I am trying to configure the puppet-logstash module via Hiera. When I make the call to hiera('profiles::logstash::config'), the return value is a concatenated string. It tells me that it cannot convert a String into a hash. shipper.pp class profiles::logstash::shipper() { $shipper_config = hiera('profiles::logstash::config') notice("${shipper_config}") class { 'logstash': ensure => 'present', version => '1.4.1-1_bd507eb', status => 'enabled', } profiles::logstash::config { $shipper_config: } include logstash } hostname.yaml classes: - os::repo - profiles::logstash::shipper profiles::logstash::config: - {content: this is a test, order: 10} Output when used with notice(): order10contentthis is a test Did I order my YAML wrong?

• Cannot access internet or remote network after connecting to Windows VPN

  - by Kiewic

  I set up a VPN by creating an incoming VPN connection (VPN server) in my Windows 8 machine at home (not a Windows Server). I forwarded the PPTP port in my router (port 1723) to this machine and enabled PPTP passthrough. In a second Windows 8 machine out of home, I created an outgoing VPN connection (VPN client). And I am able to connect to my home VPN, but I don't have access to any home resource or even internet. This is the output of the client ipconfig: And this are the settings of my VPN server: UPDATE: My VPN server has assigned the 192.168.1.144 IP adress at my home network. So, I tried setting the "IP address assignment" range from 192.168.1.150 to 192.168.1.200. And when a VPN client gets connected, it gets an address in that range, but it doesn't make any difference.

• Retrieve malicious IP addresses from Apache logs and block them with iptables

  - by Gabriel Talavera

  Im trying to keep away some attackers that try to exploit XSS vulnerabilities from my website, I have found that most of the malicious attempts start with a classic "alert(document.cookie);\" test. The site is not vulnerable to XSS but I want to block the offending IP addresses before they found a real vulnerability, also, to keep the logs clean. My first thought is to have a script constantly checking in the Apache logs all IP addresses that start with that probe and send those addresses to an iptables drop rule. With something like this: cat /var/log/httpd/-access_log | grep "alert(document.cookie);" | awk '{print $1}' | uniq Why would be an effective way to send the output of that command to iptables? Thanks in advance for any input!

• no download and install progress, no error message (no text at all!) for sudo gem install merb

  - by Delirium tremens

  I'm using ruby 4.2, rubygems 1.3.5-1ubuntu2 and Ubuntu Lucid Lynx. I installed ruby and rubygems with Synaptic. Since "The gem command will output its progress while it sucks down and installs all the necessary gems for a full Merb install. " is written at http://wiki.merbivore.com/howto/installation/gems, when I type sudo gem update --system, I get: "ERROR: While executing gem ... (RuntimeError) gem update --system is disabled on Debian. RubyGems can be updated using the official Debian repositories by aptitude or apt-get." and rubygems has list, build and help commands, I'm wondering if in Ubuntu rubygems is used only for something other than downloading. If it isn't, why isn't rubygems showing any text for sudo gem install merb?

• apache not starting in vagrant vm

  - by jimmyjambles

  I used Puphpet.com to create a Vagrant VM to be used for web development. The problem I am having is that the VM cannot start apache on boot. $ sudo /etc/init.d/apache2 start * Starting web server apache2 * * The apache2 configtest failed. Output of config test was: apache2: Syntax error on line 36 of /etc/apache2/apache2.conf: Syntax error on line 1 of /etc/apache2/mods-enabled/authz_default.load: Cannot load /usr/lib/apache2/modules/mod_authz_default.so into server: /usr/lib/apache2/modules/mod_authz_default.so: cannot open shared object file: No such file or directory Action 'configtest' failed. The Apache error log may have more information. the system is ubuntu 12, not sure what modifications I have to make to the puppet config to fix the problem.

• Grep all files in a directory and print matches with file name

  - by javanix

  I have a list of log files that I create as part of a video encoding script that I wrote. I would like to search all of them and print out certain statistics from the encode - how fast they were encoded, what settings were used, etc. I can search for the average framerate in one file via this 1 liner: cat ${filename} | grep average which outputs: work: average encoding speed for job is 23.211176 fps and search for the ratefactor: cat ${filename} | grep RF I would like to search all files in the directory and print off one, or prefereably both pieces of information along with the filename. Is there any way I can use find or grep to get this in a one-liner, or do I need to write a script? I would like output like this: /home/javanix/filename.log <RF line> <average line> I would like this to either work using FreeBSD 9 or Ubuntu 12.04.

• Computer won't reboot without waiting for a while

  - by Benjamin

  I've got an unusual problem with my computer. When ever I reboot my computer it won't boot, I get a few beeps from the BIOS and nothing else, however if I wait for a few minuets the computer will boot perfectly. I tried to count the beeps and I get around 7-9 of them; the first two are noticeably closer together than the rest. [Edit: I'm now reasonably confident it's 1 long followed by 8 short beeps.

• Versioning APIs

  - by Sharon

  Suppose that you have a large project supported by an API base. The project also ships a public API that end(ish) users can use. Sometimes you need to make changes to the API base that supports your project. For example, you need to add a feature that needs an API change, a new method, or requires altering of one of the objects, or the format of one of those objects, passed to or from the API. Assuming that you are also using these objects in your public API, the public objects will also change any time you do this, which is undesirable as your clients may rely on the API objects remaining identical for their parsing code to work. (cough C++ WSDL clients...) So one potential solution is to version the API. But when we say "version" the API, it sounds like this also must mean to version the API objects as well as well as providing duplicate method calls for each changed method signature. So I would then have a plain old clr object for each version of my api, which again seems undesirable. And even if I do this, I surely won't be building each object from scratch as that would end up with vast amounts of duplicated code. Rather, the API is likely to extend the private objects we are using for our base API, but then we run into the same problem because added properties would also be available in the public API when they are not supposed to be. So what is some sanity that is usually applied to this situation? I know many public services such as Git for Windows maintains a versioned API, but I'm having trouble imagining an architecture that supports this without vast amounts of duplicate code covering the various versioned methods and input/output objects. I'm aware that processes such as semantic versioning attempt to put some sanity on when public API breaks should occur. The problem is more that it seems like many or most changes require breaking the public API if the objects aren't more separated, but I don't see a good way to do that without duplicating code.

• HDMI connection does not support HDCP

  - by mroggi

  Hi, My problem: error message when playing blu-ray movies stating that the HDCP encryption could not be established. My setup: A new projector (EPSON EMP TW700) with a HDCP-compliant HDMI port a PC with a brand-new graphics adapter (Sapphire HD 4350 512MB DDR2) supporting HDCP Connection made with a DVI cable (it's installed in my wall) and a DVI-HDMI adapter to connect the projector Latest drivers and software My questions: What can I do to establish the HDCP connection? Would it help to use the HDMI output of the graphics adapter instead of the DVI (could it be that the HDCP chip is only supported on HDMI?) Any other ideas? I am very thankful for any hint.

• What's about Java?

  - by Silviu Turuga

  What is Java? In very short words, Java is a programming language that let you make an application that can be run on different operating systems, no matter we are talking about Windows, Mac OS, Linux or even embedded devices, such as RaspberryPi. When you compile a Java program, instead of getting a binary output as you get on other programming languages, you'll get a Java intermediate code, called Java bytecode. This is interpreted at run time, by a virtual machine that is specifically for the hardware and operating system you are using. What Java do i need? There are 5 major versions of Java: Java SE(Standard Edition) - this is what I'll use on most of my tutorials. Most of the examples will run on Java 6, but for others you'll need Java 7. Java EE (Enterprise Edition) - used for enterprise development Java ME (Micro Edition) - for running Java on mobile and different embedded devices such as PDAs, TV set-top boxes, printers, etc. Java Embedded - for some embedded devices such as Raspberry Pi, where the resources are limited JavaFX - to develop rich content User Interfaces. This is also something that will use a lot. More detailed information can be found on Oracle's website If you just want to run java applications you'll need the JRE (Java Runtime Environment) installed. If you want to program and create new applications, then you'll need the JDK (Java Development Kit).  How to check if Java is already installed? From command line, if you are on Windows, or from Terminal on Mac enter the following: java -version You should get something like this, if you have java installed on your system: java version "1.6.0_37" Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909) Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode) Note: your current Java version might be different from mine. More information https://www.java.com/en/download/faq/whatis_java.xml http://en.wikipedia.org/wiki/Java_(programming_language) Next steps Install Java SDK Chose an IDE. I recommend NetBeans as it is very easy to use and also let you quickly create the GUI of your application Alternatives are Eclipse, Komodo Edit (for Mac), etc. There are plenty of solutions both free or paid.

• Xmodmap configuration

  - by Krishna S

  On my Debian Linux machine Ctrl+Alt+F1 is bound to a virtual terminal. I can see the corresponding entry by running xmodmap -pke keycode 67 = F1 XF86_Switch_VT_1 F1 XF86_Switch_VT_1 Per this thread, which I might add is consistent with what I've read elsewhere, the columns on the right hand side of = correspond to key, Shift+key, AltGr+key and Shift+AltGr+key. Given that, I don't understand how the keycode mapping for F1 (above) works for Ctrl+Alt+F1. It seems it should really be either Shift+F1 or Shift+AltGr+F1? Here's the output of xmodmap -pm on my machine: shift Shift_L (0x32), Shift_R (0x3e) lock Caps_Lock (0x25) control Control_L (0x42), Control_R (0x69) mod1 Alt_L (0x40), Alt_R (0x6c), Meta_L (0xcd) mod2 Num_Lock (0x4d) mod3 mod4 Super_L (0x85), Super_R (0x86), Super_L (0xce), Hyper_L (0xcf) mod5 ISO_Level3_Shift (0x5c), Mode_switch (0xcb) Can anybody explain it?

• Linux - Multiple service statuses with one command

  - by Jimbo

  I'm trying to retrieve a list of multiple service statuses in Unix. I'm using the service command: man page. The statuses all start with the transmission-daemon string, for example. I require the ability to list multiple services' statuses, with a single command. Here is what I'm currently trying (and failing) with: Here I'm trying to grab a list of statuses using grep. service $(ls /etc/init.d | grep "transmission-daemon") status Here I'm trying to list all statuses, and then grep for them. service --status-all | grep "transmission-daemon" This produces the following, which isn't much help: How can I effectively achieve what I require with a single command, so that I can then continue piping to awk for further customisation? Desired example output: transmission-daemon started transmission-daemon2 stopped transmission-daemon3 started

• Broadcom BCM4313 takes ages to connect

  - by Drazgo

  I'm having issues with my broadcom BCM4313 wireless adapter.

• What arguments can I use to "sell" the BDD concept to a team reluctant to adopt it?

  - by S.Robins

  I am a bit of a vocal proponent of the BDD methodology. I've been applying BDD for a couple of years now, and have adopted StoryQ as my framework of choice when developing DotNet applications. Even though I have been unit testing for many years, and had previously shifted to a test-first approach, I've found that I get much more value out of using a BDD framework, because my tests capture the intent of the requirements in relatively clear English within my code, and because my tests can execute multiple assertions without ending the test halfway through - meaning I can see which specific assertions pass/fail at a glance without debugging to prove it. This has really been the tip of the iceberg for me, as I've also noticed that I am able to debug both test and implementation code in a more targeted manner, with the result that my productivity has grown significantly, and that I can more easily determine where a failure occurs if a problem happens to make it all the way to the integration build due to the output that makes its way into the build logs. Further, the StoryQ api has a lovely fluent syntax that is easy to learn and which can be applied in an extraordinary number of ways, requiring no external dependencies in order to use it. So with all of these benefits, you would think it an easy to introduce the concept to the rest of the team. Unfortunately, the other team members are reluctant to even look at StoryQ to evaluate it properly (let alone entertain the idea of applying BDD), and have convinced each other to try and remove a number of StoryQ elements from our own core testing framework, even though they originally supported the use of StoryQ, and that it doesn't impact on any other part of our testing system. Doing so would end up increasing my workload significantly overall and really goes against the grain, as I am convinced through practical experience that it is a better way to work in a test-first manner in our particular working environment, and can only lead to greater improvements in the quality of our software, given I've found it easier to stick with test first using BDD. So the question really comes down to the following: What arguments can I use to really drive the point home that it would be better to use StoryQ, or at the very least apply the BDD methodology? Can you point me to any anecdotal evidence that I can use to support my argument to adopt BDD as our standard method of choice? What counter arguments can you think of that could suggest that my wish to convert the team efforts to BDD might be in error? Yes, I'm happy to be proven wrong provided the argument is a sound one. NOTE: I am not advocating that we rewrite our tests in their entirety, but rather to simply start working in a different manner for all future testing work.

• Automatically keep your local git repos clean

  - by kerry

  Most developers using git are probably aware of a command ‘git gc’ that has to be run from time to time when you notice your git commands are running a little slow. This command cleans up your git repo and makes sure everything is nice and tidy. If you have not run this command lately, you will notice a huge performance increase in your git commands after running. It’s a bit annoying to have to run this command when you notice that your git performance is suffering. The command also takes a while if you have not run it recently. With this in mind, I decided to create a method to automatically run this command from time to time. So I decided to overload cd similar to how rvm does. All you have to do is paste the method in your .profile file and it will run the command every time you enter a directory with a git repo. You’ll notice a little pause when entering the directory, it’s not insufferable but if you would prefer, you can add an & to the end of the command to have it run in the background. I chose the pause over the pid output of the background command. Here it is in all it’s glory. View the code on Gist.

• How to bulk mail-enable contacts from AD in Exchange 2007?

  - by George Hewitt

  Hello, We have several thousand 'contacts' setup in AD already for a faxing system. We're migrating to an online fax provider that uses e-mail rather than plain old telephone. So, we've bulk edited all the AD records so that the 'mail' attribute is populated with the right e-mail address in the right format. Now, how do we enable these contacts within Exchange 2007? I've looked through http://technet.microsoft.com/en-us/library/bb684891.aspx but that only seems to talk about manually editing the CSV output to specify the external addresses. AD already knows the external e-mail addresses - I just need the info in Exchange! Any thoughts?

• wireless blocked after installing ubuntu 12.04

  - by Cornelia Frank

  I am using a lenovo S10-3 ideapad; had no problems with earlier version of ubuntu, only since installing 12.04. Have looked through many of the questions on the same issue and tried potential solutions but cannot seem to solve my problem. The hardware switch is in 'on' position and the wireless light comes on very briefly (2-3 sec) when the laptop starts up but then goes off and stays off. Pressing FN+F5 does nothing at all. I'd be grateful for any assistance.

• Multiplayer tile based movement synchronization

  - by Mars

  I have to synchronize the movement of multiple players over the Internet, and I'm trying to figure out the safest way to do that. The game is tile based, you can only move in 4 directions, and every move moves the sprite 32px (over time of course). Now, if I would simply send this move action to the server, which would broadcast it to all players, while the walk key is kept being pressed down, to keep walking, I have to take this next command, send it to the server, and to all clients, in time, or the movement won't be smooth anymore. I saw this in other games, and it can get ugly pretty quick, even without lag. So I'm wondering if this is even a viable option. This seems like a very good method for single player though, since it's easy, straight forward (, just take the next movement action in time and add it to a list), and you can easily add mouse movement (clicking on some tile), to add a path to a queue, that's walked along. The other thing that came to my mind was sending the information that someone started moving in some direction, and again once he stopped or changed the direction, together with the position, so that the sprite will appear at the correct position, or rather so that the position can be fixed if it's wrong. This should (hopefully) only make problems if someone really is lagging, in which case it's to be expected. For this to work out I'd need some kind of queue though, where incoming direction changes and stuff are saved, so the sprite knows where to go, after the current movement to the next tile is finished. This could actually work, but kinda sounds overcomplicated. Although it might be the only way to do this, without risk of stuttering. If a stop or direction change is received on the client side it's saved in a queue and the char keeps moving to the specified coordinates, before stopping or changing direction. If the new command comes in too late there'll be stuttering as well of course... I'm having a hard time deciding for a method, and I couldn't really find any examples for this yet. My main problem is keeping the tile movement smooth, which is why other topics regarding synchronization of pixel based movement aren't helping too much. What is the "standard" way to do this?

• cleaning up pdftotext font issues

  - by mankoff

  I'm using pdftotext to make an ASCII version of a PDF document (made with LaTeX), because collaborators prefer a simple document in MS word. The plain text version I see looks good, but upon closer inspection the f character seems to be frequently mis-converted depending on what characters follow. For example, fi and fl often seem to become one special character, which I will try to paste here: ? and ?. What is the best way to clean up the output of pdftotext? I am thinking sed might be the right tool, but am not sure how to detect these special characters.

• Fatal X server error: Failed to submit to batchbuffer

  - by Jan

  Ubuntu 10.04 Lucid Lynx used to run fine on my computer. Since a few weeks, my X server crashes out of the blue while the computer is idle and I'm logged into a Gnome session. (I'm then greeted with a new GDM login prompt). After the crash, /var/log/gdm/:0.log.1 has the following: Fatal server error: Failed to submit batchbuffer: Input/output error Please consult the The X.Org Foundation support at http://wiki.x.org for help. ~/.xsession-errors.old has symptoms of X clinets dying: nm-applet: Fatal IO error 11 (Die Ressource ist zur Zeit nicht verfügbar) on X server :0.0. dmesg says: [191848.390081] [drm:i915_hangcheck_elapsed] ERROR Hangcheck timer elapsed...

• How to write regex in asp.net MVC 3 razor

  - by anirudha

  here is a small trick to write regex and exceptional code in MVC3. first trick is use @@ instead of @ it’s work don’ worry output goes @ not @@. second trick is that you can use <text></text> tag in MVC to use some code who give error because viewengine does not accept them. like var pattern = new RegExp(/^(("[\w-\s]+")|([\w-]+(?:\.[\w-]+)*)|("[\w-\s]+")([\w-]+(?:\.[\w-]+)*))(@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$)|(@\[?((25[0-5]\.|2[0-4][0-9]\.|1[0-9]{2}\.|[0-9]{1,2}\.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\]?$)/i);   this regex not work because it’s use @ so replace them to @@ e var pattern = new RegExp(/^(("[\w-\s]+")|([\w-]+(?:\.[\w-]+)*)|("[\w-\s]+")([\w-]+(?:\.[\w-]+)*))(@@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$)|(@@\[?((25[0-5]\.|2[0-4][0-9]\.|1[0-9]{2}\.|[0-9]{1,2}\.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\]?$)/i); now it will work. second way is that use text tag in MVC to make them work like <text> function isValidEmailAddress(emailAddress) { var pattern = new RegExp(/^(("[\w-\s]+")|([\w-]+(?:\.[\w-]+)*)|("[\w-\s]+")([\w-]+(?:\.[\w-]+)*))(@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$)|(@\[?((25[0-5]\.|2[0-4][0-9]\.|1[0-9]{2}\.|[0-9]{1,2}\.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\.){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})\]?$)/i); return pattern.test(emailAddress); } </text>
