  • Mouse buttons and all keyboard buttons except alt and super randomly stops working

    - by bobbaluba
    A couple of times lately, unity appears to not accept button presses from neither the mouse or the keyboard. This happens after a random amount of time, usually a couple of hours, or right after boot. The weird thing is: I can still move the mouse around. I can press alt to get the unity menu thingy (but i can't type anything in it) I can press super to show/hide the unity search. None of the applications seem to get the input Ive tried connecting a second mouse, same issue I can press ctrl+alt+f1 to drop to a shell tty The shell works fine Now, this is definitely a bug, probably in unity(?), but it's hard to search for when I don't know what's causing it. Is there something I can do to debug? I've found some people that appears to be having the same problem with the mouse only, but most of the time, their questions are unanswered or closed for being too specific. What would be a good strategy to fix this? Should I report it as a bug?

  • Oracle Keeps Growing Partner Certifications with Addition of McAfee

    - by Ted Davis
    Viruses stink. Whether it’s the common cold virus, Goatpox virus – yes it exists -- or a computer virus, you name it, viruses stink. When it comes to our computer server infrastructure we all want to make sure our servers are secure from any malware out there. Additionally, installation of anti-virus software is a requirement by many governments and for many enterprises both large and small. Because of the growth of Oracle Linux in their customer base, McAfee recently certified their “McAfee VirusScan Enterprise for Linux” on Oracle Linux.  It delivers always-on, real-time anti-virus protection for Linux environments. Its unique, Linux-based on-access scanner constantly monitors the system for potential attacks. While there have been few viruses found on Linux, you can now feel secure running Oracle Linux in your infrastructure with McAfee on top. We are happy to introduce McAfee into the Oracle Linux family of certified applications

  • Phones, Nokia, Microsoft and More

    - by Bill Evjen
    The phone revolution that is under way at the moment is insanely interesting and continuously full of buzz about directions, failures, and promises. The movement started with Apple completely reinventing what a smart phone was all about and now we have the followers. Though – don’t dismiss the followers, they are usually the ones that come out with the leap frog products when most of the world is thinking about jumping on. Remember the often used analogy – the USA invented the TV – but it was Japan that took it to the next level and now all TVs are from somewhere else other than the USA. Really there are two camps for the phones – the Cool Kids and other kids that no one wants to hang out with anymore. When it comes to cool – for some reason, the phone is an important part of that factor. Everyone wants to show their phone and its configuration (apps installed, etc) to their friends as a sign of (1) “I have money” and (2) I have smarts/tastes/style/etc when it comes to my applications that are on my phone. For those that don’t know – the Cool Kids include: Apple – this is quite obvious as everything Apple produces is in the cool camp. Just having an Apple product on your person means you can dance. Google – this is one of the more interesting releases as they have created something called Android (which in it’s own right is a major brand in itself). Microsoft – you might be saying “Really, Microsoft is cool?”. I would argue that they are indeed cool as it is now associated with XBOX 360, Kinect, and Windows 7. Gone are the days of Bob and that silly paperclip. Well – that’s it. There is nobody else I would stick in that camp. The other kids that weren’t picked for that dodgeball team include: Nokia Motorola Palm Blackberry and many many more The sad part of all this is that no matter what this second camp does now, it won’t be able to get out of this bucket easily. They will always be associated as yesterday’s technology and that association will drive the sales of the phone purchasers of the world. For those in that group, the only possible way out is to get invited to the cool club by one of the cool club members in the hope that their coolness somehow rubs off. To me, this is the move that Nokia is making. They are at this point where they have realized that they don’t have the full scope of the required end to end solution to make this all work. They have the plants to build the phones and the reach of the retailers that sell what they have. What they are missing is the proper operating system for the new world of multi-touch form factor phones. Even the companies that come up with some sort of new operating system for this type of new device, they are still associated with the yesterday and lack the developer community behind them to be the real wave of adoption that this market needs. Think about that – this is a major different between Nokia/Blackberry when you compare it to the likes of Apple, Google, and Microsoft. These three powerhouses having a very large and strong development community that will eagerly take on new initiatives using the skillsets that they have already cultivated over the years of already working with the company. This then results in a plethora of applications that are then placed on an app store of some kind. The developer gets a cut and then Apple/Google/Microsoft then get their cut. It is definitely a win-win. None of the other phone companies and wannabies can provide the same results. What Microsoft was missing was the major phone manufactures coming on board to create and push forward with the phones that are required to start the wave. This is where Nokia can come in and help Microsoft. They have the ability to promote the Windows Phone operating system on a new wave of phones. This does mean that Nokia will sell phones, but they lose out on the application store that they might have been thinking about making some money on as well as controlling the end to end solution. What is interesting is in questioning to oneself if Microsoft will purchase Nokia. It really depends upon how they want to compete and with whom Microsoft views as the major competitor. For instance, they can purchase Nokia and have their own hardware company and distribution network for phones – thereby taking on a model that is quite similar to Apple. On the other hand, they could just leave it up to the phone hardware companies such as Nokia and others to build and promote phones in a model that is similar to Google. Both ways have pluses and minuses. If they own the phone manufacturer, they really can put some thought into the design and technical specifications of the phone that is really designed to exactly how they want it. Microsoft has shown that they have this ability – especially with the XBOX initiative they have done over the years. Think about how good and powerful they have moved forward with XBOX – and I am not talking about just copying what others are doing, but coming up with leapfrog products that are steps ahead of everyone else. Though, if they didn’t do it themselves, they could then leave it up to the phone manufacturers to drive each other to build better and better phones that run the Microsoft OS – competition drives better products. We have seen this with the Android line of phones that are out there on the market. I have read a lot about Nokia investors really upset about the new Microsoft relationship – but really, this is a great thing. I for one am a fan of this relationship (I am also a Nokia stock holder btw). This will mean better days for Nokia.

  • How do I Fallback to Older DirectX Versions?

    - by smoth190
    I had a feeling that it would be easier to tackle this problem before I got too deep into development (unless, of course if that's a bad idea/the hard way, please inform me...). I'm creating my game to be run ideally on DirectX 11, however, I want to offer it on DirectX 10, and I'm unsure if it is worth offering it for DirectX 9 for XP users. I'm not too sure how this fallback even works, as I can't find many articles on the internet. If someone could give me an in-depth article, that would be great. I've read a little about how since DirectX11 is completely absent on XP, it is hard to even check for support. Someone mentioned having multiple applications for each version, is this a good idea? Thanks to anyone who can point me in the right direction here.

  • 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.

  • Use-cases for node.js and c#

    - by Chase Florell
    I do quite a bit of ASP.NET work (C#, MVC), but most of it is typical web development. I do Restful architecture using CRUD repositories. Most of my clients don't have a lot of advanced requirements within their applications. I'm now looking at node.js and it's performance implications (I'm addicted to speed), but I haven't delved into it all that much. I'm wondering if node.js can realistically replace my typical web development in C# and ASP.NET MVC (not rewriting existing apps, but when working on new ones) node.js can complement an ASP.NET MVC app by adding some async goodness to the existing architecture. Are there use-cases for/against C# and node.js? Edit I love ASP.NET MVC and am super excited with where it's going. Just trying to see if there are special use cases that would favor node.js

  • ASP.NET: Using pickup directory for outgoing e-mails

    - by DigiMortal
    Sending e-mails out from web applications is very common task. When we are working on or test our systems with real e-mail addresses we don’t want recipients to receive e-mails (specially if we are using some subset of real data9. In this posting I will show you how to make ASP.NET SMTP client to write e-mails to disc instead of sending them out. SMTP settings for web application I have seen many times the code where all SMTP information is kept in app settings just to read them in code and give to SMTP client. It is not necessary because we can define all these settings under system.web => mailsettings node. If you are using web.config to keep SMTP settings then all you have to do in your code is just to create SmtpClient with empty constructor. var smtpClient = new SmtpClient(); Empty constructor means that all settings are read from web.config file. What is pickup directory? If you want drastically raise e-mail throughput of your SMTP server then it is not very wise plan to communicate with it using SMTP protocol. it adds only additional overhead to your network and SMTP server. Okay, clients make connections, send messages out and it is also overhead we can avoid. If clients write their e-mails to some folder that SMTP server can access then SMTP server has e-mail forwarding as only resource-eager task to do. File operations are way faster than communication over SMTP protocol. The directory where clients write their e-mails as files is called pickup directory. By example, Exchange server has support for pickup directories. And as there are applications with a lot of users who want e-mail notifications then .NET SMTP client supports writing e-mails to pickup directory instead of sending them out. How to configure ASP.NET SMTP to use pickup directory? Let’s say, it is more than easy. It is very easy. This is all you need. <system.net>   <mailSettings>     <smtp deliveryMethod="SpecifiedPickupDirectory">       <specifiedPickupDirectory pickupDirectoryLocation="c:\temp\maildrop\"/>     </smtp>   </mailSettings> </system.net> Now make sure you don’t miss come points: Pickup directory must physically exist because it is not created automatically. IIS (or Cassini) must have write permissions to pickup directory. Go through your code and look for hardcoded SMTP settings. Also take a look at all places in your code where you send out e-mails that there are not some custom settings used for SMTP! Also don’t forget that your mails will be written now to pickup directory and they are not sent out to recipients anymore. Advanced scenario: configuring SMTP client in code In some advanced scenarios you may need to support multiple SMTP servers. If configuration is dynamic or it is not kept in web.config you need to initialize your SmtpClient in code. This is all you need to do. var smtpClient = new SmtpClient(); smtpClient.DeliveryMethod = SmtpDeliveryMethod.SpecifiedPickupDirectory; smtpClient.PickupDirectoryLocation = pickupFolder; Easy, isn’t it? i like when advanced scenarios end up with simple and elegant solutions but not with rocket science. Note for IIS SMTP service SMTP service of IIS is also able to use pickup directory. If you have set up IIS with SMTP service you can configure your ASP.NET application to use IIS pickup folder. In this case you have to use the following setting for delivery method. SmtpDeliveryMethod.PickupDirectoryFromIis You can set this setting also in web.config file. <system.net>   <mailSettings>     <smtp deliveryMethod="PickupDirectoryFromIis" />   </mailSettings> </system.net> Conclusion Who was still using different methods to avoid sending e-mails out in development or testing environment can now remove all the bad code from application and live on mail settings of ASP.NET. It is easy to configure and you have less code to support e-mails when you use built-in e-mail features wisely.

  • Customizing JBar for Notifications

    - by Ryan Ohs
    Lately I've been using JBar, a very neat jQuery plugin for displaying notifications in my web applications. Unfortunately the original version of JBar only supports binding to the click event of a DOM item. In order to get around this limitation I have modified the source code and posted an updated version on my GitHub account here. The modified version allows you to display a JBar notification by calling a method. I typically use it to display succes or failure messages when doing Ajax calls. I have also included some additional CSS and JS so that you can diplay different styles of notifications. showNotification(message) shows a green "success" message. showWarning(message) shows an orange "warning" message. showMessage(message, className) allows you to specify a custom class to apply to the notification for additional styling purposes. A web page with samples is included.   Get the code here.

  • Creating and Using a jQuery Plug-in in ASP.NET Web Forms

    - by bipinjoshi
    Developers often resort to code reuse techniques in their projects. As far as ASP.NET framework server side programming is concerned classes, class libraries, components, custom server controls and user controls are popular code reuse techniques. Modern ASP.NET web applications no longer restrict themselves only to server side programming. They also make use of client side scripting to render rich web forms. No wonder that Microsoft Visual Studio 2010 includes jQuery library by default as a part of newly created web site. If you are using jQuery for client side scripting then one way to reuse your client side code is to create a jQuery plug-in. Creating a plug-in allows you to bundle your reusable jQuery code in a neat way and then reuse it across web forms. In this article you will learn how to create a simple jQuery plug-in from scratch. You will also learn about certain guidelines that help you build professional jQuery plug-ins.http://www.bipinjoshi.net/articles/aae84a03-b4a8-477d-b087-5b7f42935220.aspx

  • How to open files which are located in VirtualBox's Guest Machine from Netbeans of Host Machine

    - by Bakhtiyor
    I have Ubuntu 10.04 installed in my Host Machine and it has VirtualBox. I have Guest Machine wich runs Ubuntu 10.10. I have NetBeans installed in Host Machine and need to open my project files which are located in Guest Machine. The reason I need it is because in my working place I have not access to install any applications, that is why I have Guest Machine where I have Web Server installed on it and also I have one web application that I am developing. I need to open that web application files from Guest Machine's Netbeans in order to modify/create new files for my web application. I have configured SSH server of Guest Machine and added port redirection in the VirtualBox so that now I can connect to it from Host Machine. But I could not find any way to open those files from Netbeans. Could anybody give me advice about how can I do that please? UPDATE I forgot to say that I don't want to use SharedFolders.

  • Easing the Journey to the Private Cloud with Oracle Consulting

    - by MichaelM-Oracle
    By Sanjai Marimadaiah, Senior Director, Strategy & Business Development – Cloud Solutions, Oracle Consulting Services Business leaders are now leading the charge on how their firms can profit from cloud solutions. Agility and innovation are becoming the primary drivers of the business case for the cloud, even more than the anticipated cost savings. Leaders need to find the right strategy and optimize the use of cloud-based applications across their enterprise-computing infrastructure. The Problem – Current State With prevalent IT practices, many organizations find that they run multiple IT solutions serving similar business needs. This has led to the proliferation of technology stacks, for example: Oracle 10g on Sun T4 running Solaris 9; Oracle 11g on Exadata running Linux; or Oracle 12c on commodity x86 servers. This variance has a huge impact on an organization’s agility and expenses, and requires IT professionals with varied skills as well as on-going training for different systems and tools. Fortunately there is a practical business strategy to overcome this unneeded redundancy. Thus begins a journey to the right cloud computing solution. The Solution – Cloud Services from Oracle Consulting Services (OCS) Oracle Consulting Services (OCS ) works closely with our clients as trusted advisors to proactively respond to business needs and IT concerns. OCS understands that making the transition to cloud solutions begins with a strategic conversation, based on its deep expertise for successfully completing private cloud service engagements with several companies. For a journey to the cloud, Oracle Consulting Services leads the client through four phases– standardization, consolidation, service delivery, and enterprise cloud – to achieve optimal returns. Phase 1 - Standardization Oracle Consulting Services (OCS) works with clients to evaluate their business requirements and propose a set of standard solutions stacks for various IT solutions. This is an opportune time to evaluate cloud ready solutions, such as Oracle 12c, Oracle Exadata, and the Oracle Database Appliance (ODA). The OCS consultants, together with the delivery team, then turn to upgrading and migrating existing solution stacks to standardized offerings. OCS has the expertise and tools to complete this stage in a fraction of the time required by other IT services companies. Clients quickly realize cost savings in tools, processes, and type/number of resources required. This standardization also improves agility of the IT organizations and their abilities to respond to the needs of various business units. Phase 2 - Consolidation During the consolidation phase, OCS consultants programmatically consolidate hundreds of databases into a smaller number of servers to improve utilization, reduce floor space, and optimize maintenance costs. Consolidation helps clients realize huge savings in CapEx investments and shrink OpEx costs. The use of engineered systems, such as Oracle Exadata, greatly reduces the client’s risk of moving to a new solution stack. OCS recommends clients to pursue Phase 1 (Standardization) and Phase 2 (Consolidation) simultaneously to reduce the overall time, effort, and expense of the cloud journey. Phase 3 - Service Delivery Once a client is on a path of standardization and consolidation, OCS consultants create Service Catalogues based on the SLAs requirements and the criticality of the solutions. The number and types of Service Catalogues (Platinum, Gold, Silver, Bronze, etc.) vary from client to client. OCS consultants also implement a variety of value-added cloud solutions, including monitoring, metering, and charge-back solutions. At this stage, clients are able to achieve a high level of understanding in their cloud journey. Their IT organizations are operating efficiently and are more agile in responding to the needs of business units. Phase 4 - Enterprise Cloud In the final phase of the cloud journey, the economics of the IT organizations change. Business units can request services on-demand; applications can be deployed and consumed on a pay-as-you-go model. OCS has the expertise and capabilities to establish processes, programs, and solutions required for IT organizations to transform how they interact with business units. The Promise of Cloud Solutions Depending the size and complexity of their business model, some clients are able to abbreviate some phases of their cloud journey. Cloud solutions are still evolving and there is rapid pace of innovation to transform how IT organizations operate. The lesson is clear. Cloud solutions hold a lot of promise for business agility. Business leaders can now leverage an additional set of capabilities and services. They can ramp up their pace of innovation. With cloud maturity, they can compete more effectively in their respective markets. But there are certainly challenges ahead. A skilled consulting services partner can play a pivotal role as a trusted advisor in the successful adoption of cloud solutions. Oracle Consulting Services has expertise and a portfolio of services to help clients succeed on their journey to the cloud.

    In life it doesnt matter if you do one thing for 15 years. You will end up waking one day and asking stuff that are equal to "how do i walk?" :) My specific question is that as a new entrant to C# and OOP i am stepping into many little "details" that need to be addressed. Written a lot of code in VB.NET / cobol / simple php e.t.c surely does not help much into the OOP world... So , even after reading entry level books for C# and watching some videos i recently found out about the "factory model design" for applications. I would appreciate if any of you guys recomment some reading on application design architecture for further reading...

    - by user3215
    Does anybody know how to apply a customized user settings to other existing or new users?. Something like a customized preferences settings for system wide so that everybody posses those settings and below will explain in clear what I actually ment. On every machine I will install the following: Eclipse Mysql Query Browser and Admin Mysql Workbench Oracle VirtualBox Thunderbird ----------- ----------- ----------- If I install them by apt, this will automatically create shortcuts in Applications but when I build them from source or extract the tar ball, I will have to add New Item at it's relevant place going to System-->Preferences-->Main Menu to make them available as a shortcuts and this settings are applied only for the account I login and perform them. How could I make this preferences settings for complete system wide which applies for all users? or if there is a way to apply a customized user settings to other users will also be ok.

  • Computer Networks UNISA - Chap 15 &ndash; Network Management

    - by MarkPearl
    After reading this section you should be able to Understand network management and the importance of documentation, baseline measurements, policies, and regulations to assess and maintain a network’s health. Manage a network’s performance using SNMP-based network management software, system and event logs, and traffic-shaping techniques Identify the reasons for and elements of an asset managements system Plan and follow regular hardware and software maintenance routines Fundamentals of Network Management Network management refers to the assessment, monitoring, and maintenance of all aspects of a network including checking for hardware faults, ensuring high QoS, maintaining records of network assets, etc. Scope of network management differs depending on the size and requirements of the network. All sub topics of network management share the goals of enhancing the efficiency and performance while preventing costly downtime or loss. Documentation The way documentation is stored may vary, but to adequately manage a network one should at least record the following… Physical topology (types of LAN and WAN topologies – ring, star, hybrid) Access method (does it use Ethernet 802.3, token ring, etc.) Protocols Devices (Switches, routers, etc) Operating Systems Applications Configurations (What version of operating system and config files for serve / client software) Baseline Measurements A baseline is a report of the network’s current state of operation. Baseline measurements might include the utilization rate for your network backbone, number of users logged on per day, etc. Baseline measurements allow you to compare future performance increases or decreases caused by network changes or events with past network performance. Obtaining baseline measurements is the only way to know for certain whether a pattern of usage has changed, or whether a network upgrade has made a difference. There are various tools available for measuring baseline performance on a network. Policies, Procedures, and Regulations Following rules helps limit chaos, confusion, and possibly downtime. The following policies and procedures and regulations make for sound network management. Media installations and management (includes designing physical layout of cable, etc.) Network addressing policies (includes choosing and applying a an addressing scheme) Resource sharing and naming conventions (includes rules for logon ID’s) Security related policies Troubleshooting procedures Backup and disaster recovery procedures In addition to internal policies, a network manager must consider external regulatory rules. Fault and Performance Management After documenting every aspect of your network and following policies and best practices, you are ready to asses you networks status on an on going basis. This process includes both performance management and fault management. Network Management Software To accomplish both fault and performance management, organizations often use enterprise-wide network management software. There various software packages that do this, each collect data from multiple networked devices at regular intervals, in a process called polling. Each managed device runs a network management agent. So as not to affect the performance of a device while collecting information, agents do not demand significant processing resources. The definition of a managed devices and their data are collected in a MIB (Management Information Base). Agents communicate information about managed devices via any of several application layer protocols. On modern networks most agents use SNMP which is part of the TCP/IP suite and typically runs over UDP on port 161. Because of the flexibility and sophisticated network management applications are a challenge to configure and fine-tune. One needs to be careful to only collect relevant information and not cause performance issues (i.e. pinging a device every 5 seconds can be a problem with thousands of devices). MRTG (Multi Router Traffic Grapher) is a simple command line utility that uses SNMP to poll devices and collects data in a log file. MRTG can be used with Windows, UNIX and Linux. System and Event Logs Virtually every condition recognized by an operating system can be recorded. This is typically done using event logs. In Windows there is a GUI event log viewer. Similar information is recorded in UNIX and Linux in a system log. Much of the information collected in event logs and syslog files does not point to a problem, even if it is marked with a warning so it is important to filter your logs appropriately to reduce the noise. Traffic Shaping When a network must handle high volumes of network traffic, users benefit from performance management technique called traffic shaping. Traffic shaping involves manipulating certain characteristics of packets, data streams, or connections to manage the type and amount of traffic traversing a network or interface at any moment. Its goals are to assure timely delivery of the most important traffic while offering the best possible performance for all users. Several types of traffic prioritization exist including prioritizing traffic according to any of the following characteristics… Protocol IP address User group DiffServr VLAN tag in a Data Link layer frame Service or application Caching In addition to traffic shaping, a network or host might use caching to improve performance. Caching is the local storage of frequently needed files that would otherwise be obtained from an external source. By keeping files close to the requester, caching allows the user to access those files quickly. The most common type of caching is Web caching, in which Web pages are stored locally. To an ISP, caching is much more than just convenience. It prevents a significant volume of WAN traffic, thus improving performance and saving money. Asset Management Another key component in managing networks is identifying and tracking its hardware. This is called asset management. The first step to asset management is to take an inventory of each node on the network. You will also want to keep records of every piece of software purchased by your organization. Asset management simplifies maintaining and upgrading the network chiefly because you know what the system includes. In addition, asset management provides network administrators with information about the costs and benefits of certain types of hardware or software. Change Management Networks are always in a stage of flux with various aspects including… Software changes and patches Client Upgrades Shared Application Upgrades NOS Upgrades Hardware and Physical Plant Changes Cabling Upgrades Backbone Upgrades For a detailed explanation on each of these read the textbook (Page 750 – 761)

  • Microsoft launches two new Data Centres for Azure in US to meet growing demand

    - by Gopinath
    In order to meet the growing demand for Windows Azure in US, Microsoft has launched two new data centres in US – East US and West US. With the addition of these two data centres the number of Azure data centres across the globe has grown to 8 and 4 among them are located in US. The two new data centres are providing Computer and Storage resources and few enthusiastic customers already deployed their applications. The other services like SQL Azure and AppFabric will be offered by these data centres in the coming months. The addition of new data centres is a good sign to Microsoft as the customer demand for their Cloud offering is growing. Amazon Web Services is the pioneer in Cloud Computing and they offer wider range of Cloud Services compared to Microsoft. Source: Windows Azure Blog

  • Where can you find your first customers as a freelancer?

    - by Adam Smith
    I want to start doing freelance work, but no matter how I look at it, it seems like the best way to get customers and to have work most of the time, you have to already be in the freelancing game. Most freelancers I've talked to have had the same customers over the years or got new customers because their satisfied clients referred them. What I'd like to know from the successful people here that work as freelancers is how do you start doing business when you haven't yet set foot in freelancing? I want to start small, creating websites that won't require me to hire other people other than maybe a designer I already know. (I'd like to create desktop applications as well, but I think I should keep that for later when I'm more experienced) . I thought about localized Google ads or visiting companies and meeting the people in charge there, but I wouldn't know which kind of businesses to look for or if it's even a good way to approach this. Anyone care to share their personal startup experiences / advice that can help future freelancers?

  • Open source framework quality [closed]

    - by Jonas Byström
    It's not hard to find snippets, components or tools/toolkits in the open source world which holds the quality bar really high. Myself I use git, python, linux, gcc, bash and a whole range of others on a daily basis, and I love them. But when it comes to bigger frameworks, which are intended for facilitating larger tasks of an application without much interference, I'm not as enthusiastic. I've tried a few commercial frameworks (game engines), which were okay, but all big open source frameworks which I've used myself, or which I have seen used in applications were decidedly worse than the commercial equivalent. But I'm not sure if my experience was typical. Where have bigger open source frameworks for facilitating larger tasks of an application been able to equal or exceed commercial frameworks, and how were they better?

  • How to Forward Ports to a Virtual Machine and Use It as a Server

    - by Chris Hoffman
    VirtualBox and VMware both create virtual machines with the NAT network type by default. If you want to run server software inside a virtual machine, you’ll need to change its network type or forward ports through the virtual NAT. Virtual machines don’t normally need to be reachable from outside the virtual machine, so the default is fine for most people. It actually provides some security, as it isolates the virtual machine from incoming connections.

  • Video capture Performance

    - by volting
    I have noticed high CPU utilization in a number of applications (except mplayer) which read from the embedded webcam on my laptop. Bizarrely CPU utilization varies proportionately to the level of illumination present. I know that that high CPU usage has nothing to do with rendering the video, as I have written a simple app using the OpenCV library to simply grab frames from the webcam, and cpu usage is still high. I think that mplayer might be using my GPU (and the other apps aren't), but since its not an issue with rendering, I dont think this explains anything. Cheese Low light --- ~12% CPU Bright Light ---- ~63% CPU Camorama Low light --- ~7% CPU Bright Light ---- ~30% CPU Opencv C++ library, (display in a single highgui window) Low light --- ~13% CPU Bright Light ---- ~40% CPU (same test on windows 7, 4-9%) Mplayer No problem, 1-2% regardless of light levels Note: If all I want't to do is capture a feed from my webcam I would use mplayer and forget about it, but I'm developing an application which uses the OpenCV to capture a video feed among other things, performance is important.

  • Is the abundance of Frameworks dumbing down programmers?

    - by Gratzy
    With all of the frameworks available these days ORM's DI/IoC etc. I find that many programmers are losing or don't have the problem solving skills needed to solve difficult issues. I've seen many times unexpected behaviour creep into applications and the developers unable to really dig in and find the issues. It seems to me that deep understanding of whats going on under the hood is being lost. Don't get me wrong, I'm not suggesting these frameworks aren't good and haven't moved the industry forward, only asking if as a unintended consequence developers aren't gaining the knowledge and skill needed for deep understanding of systems.

  • Is it worth to learn programming for windows?

    - by Herr Kaleun
    as a programmer, i was skeptical about (Microsoft) desktop software back in the early 2000s (i was a kid then) and yet, i was right. So i advanced to PHP in 2004 and began working on Web applications. When i look at the software world today, i really can't understand, how software for Microsoft or call it, "windows" should have a future. Is it still worth, learning it? I have a strong feeling that, in about 3-4 years, mac will have the dominance in the Personal Computer market. If i am wrong, please correct me. Thanks!
