  • What should developers know about Windows executable binary file compression?

    - by Peter Turner
    I'd never heard of this before, so shame on me, but programs like UPX can compress my files by 80% which is totally sweet, but I have no idea what the the disadvantages are in doing this. Or even what the compressor does. Website linked above doesn't say anything about dynamically linking DLLs but it mentions about compressing DESCENT 2 and about compressing Netscape 4.06. Also, it doesn't say what the tradeoffs are, only the benefits. If there weren't tradeoffs why wouldn't my linker compress the file? If I have an environment where I have one executable and 20-30 DLL's, some of which are dynamically loaded an unloaded fairly arbitrarily, but not in loops (hopefully), do I take a big hit in processing time decompressing these DLL's when they're used?

  • Sound unavailable every other session

    - by Oxwivi
    On my desktop running Oneiric, sometimes there's no sound at all, but it would work normally at other times. My setup is built ground-up from minimal Ubuntu, but since sounds work fine, at times, I don't think it is a backend dependency issue. When it works, it will play anything from regular audio files and movies to YouTube Flash players. For the record, I installed LXDE with the alsa-base and alsa-utils packages which are the only audio-related dependencies for the lubuntu-desktop. For a while, I also used persistent Oneiric live USB, and do not recall any sound issues. It's one thing to not play sound entirely, but playing sound only under some very unclear circumstances is something else. Please help me diagnose it.

  • Are all "Important security updates", updates to already installed packages?

    - by Omnicomment
    I'm running 12.04, and I've never downloaded any drivers for the installation of any peripheral devices. Yet, I noticed a fair few "Important security updates" involving drivers/utilities for HP devices/software. I understand if the default installation of Ubuntu came with a set of drivers for these devices - and the update manager, having noticed that they live on my system, went and found newer versions, but still - given I don't use any devices - I'm either forced to download an irrelevant update, sift through the updates to check applicability, or turn off Update Manager altogether: none of which are desirable. First; the obvious - can someone confirm that the list of "Important security updates" on the server that Update manager connects to, is not actually populated with every patch ever written (i.e. for all Ubuntu packages regardless of whether they're installed or not)? Unlikely, but..

  • Can't find ALL wireless networks, just my neighbours

    - by motoringeek
    Been playing with live discs since 10.10 but now have gone ahead and dual booted. I have a Acer 5742z with a Nplify 802.11b/g/n wireless connection. The install went well and drivers seem to be working. BUT, although wireless detects some local networks it doesn't find mine. I have WPA-PSK security on my modem, could this be the problem?? I don't want to change my modem settings as all my other WIFI devices are contected to it. So I need help in finding my home network. A step by step guide would be useful. I am using Windows 7 now to write this but would love it if I could use Ubuntu online. I only can when I connect an Ethernet cable. Thanks in advance.

  • WCF Keep Alive: Whether to disable keepAliveEnabled

    - by Lijo
    I have a WCF web service hosted in a load balanced environment. I do not need any WCF session related functionality in the service. QUESTION What are the scenarios in which performances will be best if keepAliveEnabled = false keepAliveEnabled = true Reference From Load Balancing By default, the BasicHttpBinding sends a connection HTTP header in messages with a Keep-Alive value, which enables clients to establish persistent connections to the services that support them. This configuration offers enhanced throughput because previously established connections can be reused to send subsequent messages to the same server. However, connection reuse may cause clients to become strongly associated to a specific server within the load-balanced farm, which reduces the effectiveness of round-robin load balancing. If this behavior is undesirable, HTTP Keep-Alive can be disabled on the server using the KeepAliveEnabled property with a CustomBinding or user-defined Binding.

  • Where can I start learning to build web applications in C#

    - by Carson Myers
    So far I've written web sites in PHP, except for a pet project of mine written in Python. I'd like to start learning C# for use on the web, but I have no idea where to start. I know nothing of .Net. Are there any good tutorials or online books etc. which give a brief intro to the .Net environment (specifically C#, and specifically for the web)? I'm not even sure what I need to install. Visual Studio I guess, but what else? Anything special, or will VS do the trick?

  • BizTalk 2009 - Project Creation Failed

    - by StuartBrierley
    A couple of weeks ago I had some issue with my BizTalk Server 2009 development environment  which resulted in a reinstall of Visual Studio 2008 and the Visual Studio 2008 Service Pack 1. Following this reinstall I began to have problems when trying to create  BizTalk 2009 projects: Error Details: “Create BizTalk Project …. Project Creation Failed” It turns out that this is a known issue with BizTalk Server 2009 and Visual Studio 2008, whereby the installation of the Visual Studio Service Pack 1 can cause corruption to the BizTalk installation preventing the creation of any new projects. To resolve this issue go to control panel > add or remove programs > Microsoft BizTalk Server 2009 and select Change or Remove.  When the window opens choose “Repair”.  Upon completion you should once again be able to create BizTalk projects.

  • Developing an ELO like point system for a multiplayer gaming site

    - by Alejandro Piad
    I'm currently working on a gaming site where users will submit virtual players for different games, like Chess, Nash, Backgammon, Go, etc. The idea is that users don't compete themselves, but through their virtual players. There will be leagues, tournaments, and other competition formats. The question is which would be a good rating system for users in this environment. Take into account that every user may have many different virtual players playing in many different games. As a general guideline I would like to guarantee the following properties: Users who have a lot of mediocre players should not score higher than users with a few very good players. A user with a high rating should not be penalized if he adds a new bad player, until he has had enough time to improve his player. Users who don't play often should not score higher than users who play every day. Thanks in advance.

  • Install using a Logitech Keyboard and mouse with bluetooth dongle?

    - by Ryan
    I'm trying to install 12.10 on my system, but my mouse and keyboard are not working during installation. I use the Logitech MX5500 Bluetooth mouse+keyboard combo with a Bluetooth dongle. My keyboard and mouse work in my UEFI bios, and during the Windows 7/8 installation. My keyboard also works in the Ubuntu screen that allows me to set options, install, use the live cd, etc, before boot. I'm wondering if anyone knows a way to get this dongle working during the installation process so that I can actually install 12.10.

  • Benchmarking CPU processing power

    - by Federico Zancan
    Provided that many tools for computers benchmarking are available already, I'd like to write my own, starting with processing power measurement. I'd like to write it in C under Linux, but other language alternatives are welcome. I thought starting from floating point operations per second, but it is just a hint. I also thought it'd be correct to keep track of CPU number of cores, RAM amount and the like, to more consistently associate results with CPU architecture. How would you proceed to the task of measuring CPU computing power? And on top of that: I would worry about a properly minimum workload induced by concurrently running services; is it correct to run benchmarking as a standalone (and possibly avulsed from the OS environment) process?

  • First Foray&ndash;About timeout

    - by SQLMonger
    It has been quite a while since I signed up for this blog site and high time that something was posted.  I have a list of topics that I will be working through and posting.  Some I am sure will have been posted by others, but I will be sticking to the technical problems and challenges that I’ve recently faced, and the solutions that worked for me.  My motto when learning something new has always been “My kingdom for an example!”, and I plan on delivering useful examples here so others can learn from my efforts, failures and successes.   A bit of background about me… My name is Clayton Groom. I am a founding partner of a consulting firm in St. Louis Missouri, Covenant Technology Partners, LLC and focus on SQL Server Data Warehouse design, Analysis Services and Enterprise Reporting solutions.  I have been working with SQL Server since the early nineties, when it still only ran on OS/2. I love solving puzzles and technical challenges.   Enough about me… On to a real problem… SSIS Connection Time outs versus Command Time outs Last week, I was working on automating the processing for a large Analysis Services cube.  I had reworked an SSIS package and script task originally posted by Vidas Matelis that automates the process of adding new and dropping old partitions to/from an Analysis Services cube.  I had the package working great, tested, and ready for deployment.  It basically performs a query against the source system to determine if there is new data in the warehouse that will require a new partition to be added to the cube, and it checks the cube to see if there are any partitions that are present that are no longer needed in a rolling 60 month window. My client uses Tivoli for running all their production jobs, and not SQL Agent, so I had to build a command line file for Tivoli to use to run the package. Everything was going great. I had tested the command file from my development workstation using an XML configuration file to pass in server-specific parameters into the package when executed using the DTExec utility. With all the pieces ready, I updated the dtsconfig file to point to the UAT environment and started working with the Tivoli developer to test the job.  On the first run, the job failed, and from what I could see in the SSIS log, it had failed because of a timeout. Other errors in the log made me think that perhaps the connection string had not been passed into the package correctly. We bumped the Connection Manager  timeout values from 20 seconds to 120 seconds and tried again. The job still failed. After changing the command line to use the /SET option instead of the /CONFIGFILE option, we tested again, and again failure. After a number more failed attempts, and getting the Teradata DBA involved to monitor and see if we were connecting and failing or just failing to connect, we determined that the job was indeed connecting to the server and then disconnecting itself after 30 seconds.  This seemed odd, as we had the timeout values for the connection manager set to 180 seconds by then.  At this point one of the DBA’s found a post on the Teradata forum that had the clues to the puzzle: There is a separate “CommandTimeout” custom property on the Data source object that may needed to be adjusted for longer running queries.  I opened up the SSIS package, opened the data flow task that generated the partition list table and right-clicked on the data source. from the context menu, I selected “Show Advanced Editor” and found the property. Sure enough, it was set to 30 seconds. The CommandTimeout property can also be edited in the SSIS Properties sheet. In order to determine how long the timeout needed to be, I ran the query from the task in the development environment and received a response in a matter of seconds.  I then tried the same query against the production database and waited several minutes for a response. This did not seem to be a reasonable response time for the query involved, and indeed it wasn’t. The Teradata DBA’s adjusted the query governor settings for the service account I was testing with, and we were able to get the response back down under a minute.  Still, I set the CommandTimeout property to a much higher value in case the job was ever started during a time of high-demand on the production server. With this change in place, the job finally completed successfully.  The lesson learned for me was two-fold: Always compare query execution times between development and production environments, and don’t assume that production will always be faster.  With higher user demands, query governors, and a whole lot more data, the execution time of even what might seem to be simple queries can vary greatly. SSIS Connection time out settings do not affect command time outs.  Connection timeouts control how long the package will wait for a response from the server before assuming the server is not available or is not responding. Command time outs control how long a task will wait for results to start being returned before deciding that the server is not responding. Both lessons seem pretty straight forward, and I felt pretty sheepish once I finally figured out what the issue was.  To be fair though, In the 5+ years that I have been working with SSIS, I could only recall one other time where I had to set the CommandTimeout property, and that memory only resurfaced while I was penning this post.

  • Installation of 11.10 on new drive (no OS)

    - by Jeffrey Vincent
    I have a Dell Dimension 600 XPS Phoenix BIOS version A03, the original HD crashed and burned. Dell didn't send OS disks (was on the original drive and no back up disks), so I am trying to install Ubuntu 11.10 on the new drive. The new drive is a Western Digital 1TB. I formatted the new drive by putting it in an enclosure and formatting it with Windows 7 on my HP system. When I put the cd in the cdrom it boots to the cd with the Advanced user screen (won't boot into the usually Windows GUI). When I try to install (or run from live Cd) I get the same error message. Same with trying the various boot options. The message is: VFS: cannot open root device "(NULL)" or unknown-block(8,1) Please append a correct "root=" boot option: Here are the available partitions: Kernal Panic- not syncing: VFS: Unable to mount rootfs on unknown-block(8,1) and then it lists Trace messages then freezing. Any help or suggestions are appreciated in advance.

  • BizTalk 2009 - Service Instances: Last 100

    - by StuartBrierley
    Having previously talked about the lack of the traditional HAT in BizTalk 2009, the question then becomes how do you replicate some of the functionality that was previsouly relied on? I have already covered the Last 100 Messages Received, the Last 100 Messages Sent, and the Last 50 Suspended Messages queries so what about service instances? The BizTalk 2009 Group Hub allows you to search for suspended service instances and also running service instances, but not the two together. In BizTalk 2004 we had a query in HAT to return the last 100 service instances.  Lets create a direct replacement in the BizTalk 2009 Hatless environment. Basically we are creating a query to search for the last one hundred tracked service instances:

  • Are there keylogger viruses that affect Ubuntu?

    - by Ryan McClure
    I just within the last few hours had my Amazon and Gmail accounts hijacked. Purchases were made through my Amazon account that I didn't authorize...in fact, I wasn't even in my room. According to Gmail, the IP address of when I got hijacked was where I live. Enough rambling, here's my question: are there keylogger viruses on Ubuntu? I am not sure if either i accidentally let my password out there somewhere, or maybe I have a keylogger. I'm currently installing ClamAV to scan for viruses. Any help would be absolutely appreciated.

  • Copying logins to another server

    - by DavidWimbush
    I'm busy setting up a new server to replace our main live server and part of that is to get the logins copied over. The database users will come over when I restore the databases but I wanted to get the logins they relate to, with the same SIDs, passwords and other properties as they have on the current server. In fact I don't even know the passwords for the logins created by our Sage accounting package - apparently they are generated by the setup using a number of ingredients unique to each installation. I did some Googling and fount this KB article: http://support.microsoft.com/kb/918992/, which more or less did the trick. It produces a set of CREATE LOGIN statements with the SIDs and hashed passwords. But it didn't include the default language, which can subtly or dramatically alter the behaviour of date-related SQL. So I added that bit and you can help yourself here.

  • Incremental file system backups

    - by brunopereira81
    I use Virtual Box a lot for distro / applications testing purposes. One of the features I simply love about it is virtual machines snapshots, its saves a state of a virtual machine and is able to restore it to its former glory if something you did went wrong without any problems and without consuming your all hard disk space. On my live systems I know how to create a 1:1 image of the file system but all the solutions I'v known will create a new image of the complete file system. Are there any programs / file systems that are capable of taking a snapshot of a current file system, save it on another location but instead of making a complete new image it creates incremental backups? To easy describe what I want, it should be as dd images of a file system, but instead of only a full backup it would also create incremental. I am not looking for clonezilla, etc. It should run within the system itself with no (or almost none) intervention from the user, but contain all the data of the file systems.

  • Thought Oracle Usability Advisory Board Was Stuffy? Wrong. Justification for Attending OUAB: ROI

    - by ultan o'broin
    Looking for reasons tell your boss why your organization needs to join the Oracle Usability Advisory Board or why you need approval to attend one of its meetings (see the requirements)? Try phrases such as "Continued Return on Investment (ROI)", "Increased Productivity" or "Happy Workers". With OUAB your participation is about realizing and sustaining ROI across the entire applications life-cycle from input to designs to implementation choices and integration, usage and performance and on measuring and improving the onboarding and support experience. If you think this is a boring meeting of middle-aged people sitting around moaning about customizing desktop forms and why the BlackBerry is here to stay, think again! How about this for a rich agenda, all designed to engage the audience in a thought-provoking and feedback-illiciting day of swirling interactions, contextual usage, global delivery, mobility, consumerizationm, gamification and tailoring your implementation to reflect real users doing real work in real environments.  Foldable, rollable ereader devices provide a newspaper-like UK for electronic news. Or a way to wrap silicon chips, perhaps. Explored at the OUAB Europe Meeting (photograph from Terrace Restaurant in TVP. Nom.) At the 7 December 2012 OUAB Europe meeting in Oracle Thames Valley Park, UK, Oracle partners and customers stepped up to the mic and PPT decks with a range of facts and examples to astound any UX conference C-level sceptic. Over the course of the day we covered much ground, but it was all related in a contextual, flexibile, simplication, engagement way aout delivering results for business: that means solving problems. This means being about the user and their tasks and how to make design and technology transforms work into a productive activity that users and bean counters will be excited by. The sessions really gelled for me: 1. Mobile design patterns and the powerful propositions for customers and partners offered by using the design guidance with Oracle ADF Mobile. Customers' and partners' developers existing ADF developers are now productive, efficient ADF Mobile developers applying proven UX guidance using ADF Mobile components and other Oracle Fusion Middleware in the development toolkit. You can find the Mobile UX Design Patterns and Guidance on Building Mobile Apps on OTN. 2. Oracle Voice and Apps. How this medium offers so much potentual in the enterprise and offers a window in Fusion Apps cloud webservices, Oracle RightNow NLP and Nuance technology. Exciting stuff, demoed live on a mobile phone. Stay tuned for more features and modalities and how you can tailor your own apps experience.  3. Oracle RightNow Natural Language Processing (NLP) Virtual Assistant technology (Ella): how contextual intervention and learning from users sessions delivers a great personalized UX for users interacting with Ella, a fifth generation VA to solve problems and seek knowledge. 4. BYOD Keynote: A balanced keynote address contrasting Fujitsu's explaining of the conceprt, challenges, and trends and setting the expectation that BYOD must be embraced in a flexible way,  with the resolute, crafted high security enterprise requirements that nuancing the BYOD concept and proposals with the realities of their world of water tight information and device sharing policies. Fascinating stuff, as well providing anecdotes to make us thing about out own DYOD Deployments. One size does not fit all. 5. Icon Cultural Surveys Results and Insights Arising: Ever wondered about the cultural appropriateness of icons used in software UIs and how these icons assessed for global use? Or considered that social media "Like" icons might be  unacceptable hand gestures in culture or enterprise? Or do the old world icons like Save floppy disk icons still find acceptable? Well the survey results told you. Challenges must be tested, over time, and context of use is critical now, including external factors such as the internet and social media adoption. Indeed the fears about global rejection of the face and hand icons was not borne out, and some of the more anachronistic icons (checkbooks, microphones, real-to-real tape decks, 3.5" floppies for "save") have become accepted metaphors for current actions. More importantly the findings brought into focus the reason for OUAB - engage with and illicit feedback though working groups before we build anything. 6. EReaders and Oracle iBook: What is the uptake and trends of ereaders? And how about a demo of an iBook with enterprise apps content?  Well received by the audience, the session included a live running poll of ereader usage. 7. Gamification Design Jam: Fun, hands on event for teams of Oracle staff, partners and customers, actually building gamified flows, a practice that can be applied right away by customers and partners.  8. UX Direct: A new offering of usability best practices, coming to an external website for you in 2013. FInd a real user, observe their tasks, design and approve, build and measure. Simple stuff to improve apps implications no end. 9. FUSE (an internal term only, basically Fusion Simplified Experience): demo of the new Face of Fusion Applications: inherently mobile, simple to use, social, personalizable and FAST, three great demos from the HCM, CRM and ICT world on how these UX designs can be used in different ways. So, a powerful breadth and depth of UX solutions and opporunities for customers and partners to engage with and explore how they can make their users happy and benefit their business reaping continued ROI from those apps investments.

  • Fast pixelshader 2D raytracing

    - by heishe
    I'd like to do a simple 2D shadow calculation algorithm by rendering my environment into a texture, and then use raytracing to determine what pixels of the texture are not visible to the point light (simply handed to the shader as a vec2 position) . A simple brute force algorithm per pixel would looks like this: line_segment = line segment between current pixel of texture and light source For each pixel in the texture: { if pixel is not just empty space && pixel is on line_segment output = black else output = normal color of the pixel } This is, of course, probably not the fastest way to do it. Question is: What are faster ways to do it or what are some optimizations that can be applied to this technique?
