  - by JuergenKress

  As Oracle's strategic layer-7 software load balancer product, Oracle Traffic Direct is fast, reliable, secure, easy-to-use and scalable; that you can deploy as the reliable entry point for all TCP, HTTP and HTTPS traffic to application servers and web servers in your network. The latest release Oracle Traffic Director 11.1.1.7.0 is available for ExaLogic and Database Appliance! For download and details please visit the Traffic Director OTN website. It this release, we have introduced some major new functionality and improvements. Web application firewall. Oracle Traffic Director supports web application firewalls. A web application firewall (WAF) is a filter or server plugin that applies a set of rules, called rule sets, to an HTTP request. Using a web application firewall, users can inspect traffic and deny requests to protect back-end applications from CSRF vulnerabilities and common attacks such as cross-site scripting. WebSocket Connections. Oracle Traffic Director handles WebSocket connections by default. WebSocket connections are long-lived and allow support for live content, games in real-time, video chatting, and so on. Support for LDAP/T3 Load Balancing. Oracle Traffic Director now supports basic LDAP/T3 load balancing at layer 7, where requests are handled as generic TCP connections for traffic tunneling. It works in full-NAT mode. Please download and try it out. For more information, check out the data sheet and the documentation.

• When creating an library published on CodePlex, how "bad" would it be for the unit-test projects to rely on commercial products?

  - by Lasse V. Karlsen

  I have started a project on CodePlex for a WebDAV server implementation for .NET, so that I can host a WebDAV server in my own programs. This is both a learning/research project (WebDAV + server portion) as well as a project I think I can have much fun with, both in terms of making it and using it. However, I see a need to do mocking of types here in order to unit-testing properly. For instance, I will be relying on HttpListener for the web server portion of the WebDAV server, and since this type has no interface, and is sealed, I cannot easily make mocks or stubs out of it. Unless I use something like TypeMock. So if I used TypeMock in the unit-test projects on this library, how bad would this be for potential users? The projects are made in C# 3.5 for .NET 3.5 and 4.0, and the project files was created with Visual Studio 2010 Professional. The actual class libraries you would end up referencing in your software would of course not be encumbered with anything remotely like this, only the unit-test libraries. What's your thoughts on this? As an example, I have in my old code-base, which is private, the ability to just initiate a WebDAV server with just this: var server = new WebDAVServer(); This constructs, and owns, a HttpListener instance internally, and I would like to verify through unit-tests that if I dispose of this server object, the internal listener is disposed of. If, on the other hand, I use the overload where I hand it a listener object, this object should not be disposed of. Short of exposing the internal listener object to the outside world, something I'm a bit loath to do, how can I in a good way ensure that the object was disposed of? With TypeMock I can mock away parts of this object even though it isn't accessed through interfaces. The alternative would be for me to wrap everything in wrapper classes, where I have complete control.

• How to selectively route network traffic through VPN on Mac OS X Leopard?

  - by newtonapple

  I don't want to send all my network traffic down to VPN when I'm connected to my company's network (via VPN) from home. For example, when I'm working from home, I would like to be able to backup my all files to the Time Capsule at home and still be able to access the company's internal network. I'm using Leopard's built-in VPN client. I've tried unchecking "Send all traffic over VPN connection." If I do that I will lose access to my company's internal websites be it via curl or the web browser (though internal IPs are still reachable). It'd be ideal if I can selectively choose a set of IPs or domains to be routed through VPN and keep the rest on my own network. Is this achievable with Leopard's built-in VPN client? If you have any software recommendations, I'd like to hear them as well.

• Glimpse: Open Source Web Development

  - by Elizabeth Ayer

  We’re delighted to announce that Red Gate will be backing Glimpse! For those of you who aren’t familiar with the project, Glimpse is an open source tool which does for the server what Firebug does for the client. It’s been in beta for the last year, and we’re very excited to give Glimpse the support and dedicated effort needed to take it to a v1 and beyond. Glimpse’s founders (Nik Molnar and Anthony van der Hoorn) have joined Red Gate, and they’re just as excited as we are about the opportunities that active development of Glimpse will bring. They will continue to write code, support the community and drive the project forward (as they’ve done since its inception). With full-time attention on growing Glimpse and its community, users and developers can expect the project to accelerate, with frequent releases of new functionality. Red Gate is excited about its first major involvement with open source. You may well be wondering, though, why Red Gate is doing this. Glimpse dovetails beautifully with Red Gate’s .NET tools, which makes Glimpse an ideal framework for plugging in advanced, paid-for functionality (like performance analysis) the way web developers want to see it. As a means to this end, we will contribute to the Glimpse open source project in order to broaden its adoption and delight web developers. Since bringing in .NET Reflector in 2008, we’ve learnt sharp lessons from the community about the right and wrong ways to engage with developers, not to mention the enduring value of free. Glimpse further shows what the .NET community can achieve through open source collaboration, and we’re looking forward to working with the Glimpse community to make something enduring and awesome. Nik and Anthony, themselves passionate advocates of community-driven software, will continue to control the Glimpse project, steering it to best meet the needs of its users and contributors. If you have any questions or queries about Glimpse, or Red Gate’s involvement in the project, please tweet with the #glimpse hashtag, contact us at Red Gate on [email protected], or post to the Glimpse Development Forum on Google Groups.

• Preparing a new physical system with VMWare

  - by Max

  I need to create a new installation of Windows, but at the same time I need this computer. So I decided to create a new physical disk from within VMWare, install windows/drivers/software and then just replace the HDD in the computer. I've bought a new HDD, split it into two partions and installed Windows 7 using the VMWare's ability to use phusical disks. I can see the windows files and directories that have been created on this partition, but when I'm replacing the HDD in the host machine it cannot boot from it. Why is that? Is it at all possible to create a bootable physical disk with VMWare or I should create a virtual disk and then use some HDD imaging tool to copy the HDD image to a physical disk? Maybe there's a better way of installing a new system and working on the computer at the same time?

• Can't add printer on Windows XP

  - by SuperFurryToad

  I've added a HP 4250 printer to about half a dozen Windows XP PCs in our office without any problems whatsoever, but for some reason I haven't been able to add it to one particular PC today. I go through the Add Printer wizard to add a local printer attached to the PC, enter the new port number as a Standard TCP/IP Port, install the driver. At the end of the wizard I get the following error message: Full error message: "windows cannot connect to the printer. either the printer name was typed incorrectly, or the specified printer has lost its connection to the server." This doesn't make any sense as I am able to ping the printer from the PC. The print spooler is running, and any firewall software on the local PC is switched off.

• Transfer nearly an entire file system to a fresh install as smoothly as possible

  - by Xander

  I've got a friend who needs his computer working in just a few hours. His files are safe, however, he managed to corrupt his main install of Windows 7. My plan is to go in with a Linux disk, copy his C:\ do a backup drive I've got and then reinstall. Restoring many of his files will be pretty simple (such as documents and such), however, things such as applications won't transfer as easily. Is there any easy way to transfer applications such as MS Office (which he needs in the morning) or other commercial software packages without having to go through the hassle of locating the keys and reinstalling them completely? I don't think just moving them over will work just because of the fact that I'm sure much of that is stored in the registry (validation stuff and such). Anyways, quick responses would be super nice! Also, additional help would be great!

• Working with fubar/refuctored code

  - by Keyo

  I'm working with some code which was written by a contractor who left a year ago leaving a number of projects with buggy, disgustingly bad code. This is what I call cowboy PHP, say no more. Ideally I'd like to leave the project as is and never touch it again. Things break, requirements change and it needs to be maintained. Part A needs to be changed. There is a bug I cannot reproduce. Part A is connect to parts B D and E. This kind of work gives me a headache and makes me die a little inside. It kills my motivation and productivity. To be honest I'd say it's affecting my mental health. Perhaps being at the start of my career I'm being naive to think production code should be reasonably clean. I would like to hear from anyone else who has been in this situation before. What did you do to get out of it? I'm thinking long term I might have to find another job. Edit I've moved on from this company now, to a place where idiots are not employed. The code isn't perfect but it's at least manageable and peer reviewed. There are a lot of people in the comments below telling me that software is messy like this. Sure I don't agree with the way some programmers do things but this code was seriously mangled. The guy who wrote it tried to reinvent every wheel he could, and badly. He stopped getting work from us because of his bad code that nobody on the team could stand. If it were easy to refactor I would have. Eventually after many 'just do this small 10minute change' situations had ballooned into hours of lost time (regardless of who on the team was doing the work) my boss finally caved in it was rewritten.

• Will Vimperator always be this awesome?

  - by Martín Fixman

  About a week ago I started using Vim, and fell completely in love with it. However, today I installed the Vimperator extension on Firefox, and through there are some problems (all of which will be solved after using it until I get used to it), I found it great. However, I'm still in the "Holy fuck this is totally awesome" phase of software testing, and in some time will go back to the "I have this thing" phase. Just to be sure, will it be a good idea to use it regularly? I want to hear experiences about users and ex-users.

• Import PDF in Inkscape without per character spacing

  - by Morinar

  I have a PDF form I imported into Inkscape. It did a pretty great job of created an SVG from it, however it appears to have given per character x coordinates to each tspan in every text block. I'm not sure, but I think this is making the FOP render that our software does ridiculously slow (running it through other renderers like IBEX it seems fine). I'd like to import it but have it not do per character positions. I can't seem to find any sort of PDF importing options at all. Does such a thing exist? Or is there perhaps some other, better freeware application I could use to generate the SVG from the PDF then use Inkscape to do adjustments from there? Thanks in advance.

• Getting Unity 3D working on legacy Nvidia card

  - by user69545

  I installed the latest nVIDIA drivers for my FX5500 card. I understand that the X server version does not officially support this driver or card but was wondering what I can do to get compiz running. I have researched for hours on this issue but cannot come up with an answer for myself. I might be doing all this for nothing but I wanted to at least try. Here is the output of my test: mike@mike-linux-box:~$ /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce FX 5500/AGP/SSE2 OpenGL version string: 2.1.2 NVIDIA 173.14.35 Not software rendered: yes Not blacklisted: no GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no So I was wondering what is the "Not Blacklisted" test? Is this the Nouveau Blacklisting? nVIDIA driver did that automatically. Does this need to be removed? Any help would be appreciated. I just want to run compiz effects. Thanks.

• Advancing my Embedded knowledge.....with a CS degree.

  - by Mercfh

  So I graduated last December with a B.S. in Computer Science, in a pretty good well known engineering college. However towards the end I realized that I actually like Assembly/Lower level C programming more than I actually enjoy higher level abstracted OO stuff. (Like I Programmed my own Device Drivers for USB stuff in Linux, stuff like that) But.....I mean we really didn't concentrate much on that in college, perhaps an EE/CE degree would've been better, but I knew the classes......and things weren't THAT much different. I've messed around with Atmel AVR's/Arduino stuff (Mostly robotics) and Linux Kernals/Device Drivers. but I really want to enhance my skills and maybe one day get a job doing embedded stuff. (I have a job now, it's An entry level software dev/tester job, it's a good job but not exactly what my passion lies in) (Im pretty good with C and certain ASM's for specific microcontrollers) Is this even possible with a CS degree? or am I screwed? (since technically my degree usually doesn't involve much embedded stuff) If Im NOT screwed then what should I be studying/learning? How would I even go about it........ I guess I could eventually say "Experienced with XXXX Microcontrollers/ASM/etc...." but still, it wouldn't be the same as having a CE/EE degree. Also....going back to college isn't an option. just fyi. edit: Any book recommendations for "getting used to this stuff" I have ARM System-on-Chip Architecture (2nd edition) it's good.....for ARM stuff lol

• Best way to replicate servers

  - by Matthew

  I currently have two servers both with linux software RAID1 configurations. They use heartbeat and DRBD to create a shared DRBD device that hosts a a exported NFS directory. The servers run Ubuntu Server with a LXDE GUI and some IP These servers are going to be placed on fishing vessels to act has redundant storage for IP cameras. My boss wants me to figure out the most efficient way to create these servers. We might be looking at pushing out several systems a week. Each configuration will be almost identical besides IP addressing. What would be the best method to automate the configuration process? We are trying to cut down on labor costs to set these up. Imaging and Proceeding are both on my mind right now

• SOA Starting Point: Methods for Service Identification and Definition

  As more and more companies start to incorporate a Service Oriented Architectural design approach into their existing enterprise systems, it creates the need for a standardized integration technology. One common technology used by companies is an Enterprise Service Bus (ESB). An ESB, as defined by Progress Software, connects and mediates all communications and interactions between services. In essence an ESB is a form of middleware that allows services to communicate with one another regardless of framework, environment, or location. With the emergence of ESB, a new emphasis is now being placed on approaches that can be used to determine what Web services should be built. In addition, what order should these services be built? In May 2011, SOA Magazine published an article that identified 10 common methods for identifying and defining services. SOA’s Ten Common Methods for Service Identification and Definition: Business Process Decomposition Business Functions Business Entity Objects Ownership and Responsibility Goal-Driven Component-Based Existing Supply (Bottom-Up) Front-Office Application Usage Analysis Infrastructure Non-Functional Requirements  Each of these methods provides various pros and cons in regards to their use within the design process. I personally feel that during a design process, multiple methodologies should be used in order to accurately define a design for a system or enterprise system. Personally, I like to create a custom cocktail derived from combining these methodologies in order to ensure that my design fits with the project’s and business’s needs while still following development standards and guidelines. Of these ten methods, I am particularly fond of Business Process Decomposition, Business Functions, Goal-Driven, Component-Based, and routinely use them in my designs.  Works Cited Hubbers, J.-W., Ligthart, A., & Terlouw , L.

• Does LDAP fit the role of a user database for an application?

  - by Spredzy

  I (my company) run a webservice that integrates pieces of few entreprisey-level software. Most of them offer different type of authentication but all offers at least LDAP. I was wondering if storing my application users directly in an LDAP directory would be a good idea. This way all the application I am using could rely on it for authentication purpose. I am aware that LDAP is not a database per se, but it is a datastore. I am also aware that there is no kind of constraints thus deleting a user on the LDAP directory won't do anything on my actual data, but this case would be taken care of with an extra process. My main question here is : is there any reason why I shouldn't use LDAP as my users database ?

• How to take advantage of two Internet connections (WiFi / Wired) ?

  - by Madhur Ahuja

  I have two separate internet connections, one through WiFi and other Wired. However, generally I have observed that Windows try to use only one ( mostly faster one/ Or Wired by preference - I am not sure). Is there a way I can take advantage of having both ? For example I can have my web browser use the wired one and my torrent software use the Wifi One. PS: This question may be regarded as duplicate but reason I am posting it again is I have not found any concrete answer for it. Two internet Connections, one LAN - how to share?

• Windows cannot access my external harddisk partition but all partition managers can

  Some weird problem happened to my Maxtor 500GB external harddisk, it all started when it once freezed during some operation. Now when I insert the drive in a USB slot, Windows asks me to format it, and if I try to open the drive from my computer it says, "not accessible".. I tried most of the major partition managers and partition recovery software. All of these can see and access my partition normally. It showing the free space and used space correctly. But Windows can't. Please help me out. Including a screenshot: On the left side, the partition manager can access and see my data in the corrupted partition, and on the right side Windows can't

  I want to watch the videos on a friends computer on the LAN without having to download it. Both of us are running ubuntu. Now one way is to ssh to his computer, cd to the directory where the video is and run the falling command: cat video.avi | ssh me@mycomputer mplayer - This works. However the problem is that I cannot seek inside the video as in can't go forward or backward in it. Is there a method by which I can watch the videos and also seek in them ? I can install any software on his comp and my comp to aid this process. I have root level access on both computers. Any suggestions ?

• Oracle Java Olympics Between Russia, Ukraine, Belarus, Ukraine and Kazakhstan

  - by Tori Wieldt

  Last month, 151 universities in 11 locations (Saint-Petersburg, Moscow, Donetsk, Tomsk, Odessa, Rostov-on-Don, Ekaterinburg, Khabarovsk, Almaty, Kiev, and Samara) competed in the second round of the Oracle Java Olympics. For two weeks in February, the best university students from Russia, Ukraine, Belarus, Ukraine and Kazakhstan were invited to compete with each other and prove just how good they are in Java programming.  A team of engineers from Oracle Development center in Saint-Petersburg prepared the set of problems to solve during the competition. To win, participants needed to show deep knowledge of Java technologies from Classloader and NIO to Reflection and JavaDB. Students in each location had a PC with Oracle JDK 1.7u2 and Netbeans 7.1.  As a testing system, the organizers used the open source software Ejudge (with several tweaks specifically for the competition).  Participants submitted their solutions to the remote server where they were tested by prepared test harnesses. All results were posted in real-time. "I followed the competition coming in from the many sites, and it was a really exciting experience, like a horse race or football game!" exclaimed Java Evangelist Alexander Belokrylov. Congratulations to everyone who competed! The Olympic finals will on April 4th.

• UDP multicast streaming of media content over WIFI

  - by sajad

  I am using vlc to stream media content over wireless network in scenario like this (from content streamer to stream receiver client): The bandwidth of wireless network is 54 Mb/s and UDP stream's required bandwidth is only 4 Mb/s; however there is trouble in receiving media stream and quality of playing specifically in multicast mode; means I can play the stream but it has jitter and does not play smoothly. In uni-cast I can stream up to 5 media streams correctly, but in multicast mode there is problem with streaming just one media! However when I stream from client some multicast streams; the wifi access-point can receive data correctly and I can see the video in "udp streamer" side correctly even when number of multicast streams increases to 9; But as you see I want to stream from streaming server and receive media in client size. Is this a typical problem of streaming real-time contents over wireless networks? Is it necessary to change configurations of my WIFI switch or it is just a software trouble? thank you

• Question about ubuntu untrusted source, gpg, keyserver

  - by ???

  I have mirrored the ubuntu archive repository (I must say it's rather huge). Then, I can apt-get install with no problem, but it prompts with following warning: WARNING: The following packages cannot be authenticated! xxxx, xxxx, ... Install these packages without verification [y/N]? Well, you can always install it. But, I can't install from the ubuntu software GUI. Which require trusted source. So, 1. How to force the GUI to install untrusted package? 2. Should I configure GPG to receive some public keys? (I've already installed ubuntu-keyring, debian-keyring, but it still untrusted) 3. Should I configure GPG to receive unknown keys from some specific keyservers, automatically?

• How do I start my career on a 3-year-old degree [on hold]

  - by Gabriel Burns

  I received my bachelor's degree in Com S (second major in math) in December 2011. I didn't have the best GPA (I was excellent at programming projects and had a deep understanding of CS concepts, but school is generally not the best format for displaying my strengths), and my only internship was with a now-defunct startup. After graduation I applied for several jobs, had a fair number of interviews, but never got hired. After a while, I got somewhat discouraged, and though I still said I was looking, and occasionally applied for something, my pace slowed down considerably. I remain convinced that software development is the right path for me, and that I could make a real contribution to someones work force, but I'm at a loss as to how I can convince anyone of this. My major problems are as follows. Lack of professional experience-- a problem for every entry-level programmer, I suppose, but everyone seems to want someone with a couple of years under their belt. Rustiness-- I've not really done any programming in about a year, and since school all I've really done is various programming competitions and puzzles. (codechef, hackerrank, etc.) I need a way to sharpen my skills. Long term unemployment-- while I had a basic fast-food job after I graduated, I've been truly unemployed for about a year now. Furthermore, no one has ever hired me as a programmer, and any potential employer is liable to wonder why. Old References-- my references are all college professors and one supervisor from my internship, none of whom I've had any contact with since I graduated. Confidence-- I have no doubt that I could be a good professional programmer, and make just about any employer glad that they hired me, but I'm aware of my red flags as a candidate, and have a hard time heading confidently into an interview. How can I overcome these problems and keep my career from being over before it starts?

• Ubuntu 13.10 AMD/ATI proprietary driver slow boot time, lengthy login/logout delays

  - by NahsiN

  Ubuntu 13.10 is causing me major headaches with my AMD/ATI HD 5770 GPU. Below is a list of problems I am currently encountering. 1) The boot time is extended by at least 25s after installing catalyst 13.4. Using open source radeon drivers, my boot time till the login screen is ~10s. With catalyst 13.4 installed, the boot time increases to ~35s. This was not the case in Ubuntu 13.04, 12.10 or 12.04. I have done the driver installation manually (instructions from wiki.cchtml.com) and using software center and there is no difference. I have not tried the catalyst 13.8 beta driver. 2) After manual installation of catalyst 13.4, I get stuck at a black screen after logging in. I have to purge fglrx to resolve the problem. I tried sudo amdconfig --initial -f but it didn't help. 3) The delay between logging in and unity being displayed is ~10-15s for BOTH open source and proprietary drivers. During the delay, it's just a black screen. Whenever I logout, there is again a ~10-15s delay with the login screen appearing stuck before lightdm allows me to enter my password again. This is ridiculous! Yes, I could stick with open source radeon drivers but I would like to install Steam and play my Valve collection on the machine. Is anybody else encountering similar issues?
