  • Due to the Classes

    - by Ratman21
    Why does it seem that I am always saying sorry (or in Japanese Gomennasi)?  Well I am late again for blog as you can see. The CCNA class’s part 1 (also known as CCENT) was, well more intense than all of the certification classes before it.   The teacher was cramming as much as he could into us during the week and it was hard to come home and do much more than fall into bed (Well I was doing still doing my Job search and checking up on my web sites and groups).   But I didn’t have much left in the way of blogging (Which by the way is now in 3 different sites). Even though it was hard some times, I really liked the fact I was getting back to something like (and mean really like, in fact I like Cisco routers than some people I know). At the class, I got some software that allows me to simulate setting up and troubles shoot Lan’s or Wan’s.   When we weren’t getting facts for the test thrown at us, we were doing labs with this software. It was fun for me to be able to use the CISCO router commands and trouble shoot router issues. Even if it was just a sim. So now it is study, study, take practices tests and do the labs. I took the week end and more off after cram CCENT week but, now I am back at it.  Also I could not keep up with my Love Dare book during week of the class. No I did not stop or forget what I already learned. I just put the next dare on hold. Well the hold is off starting tomorrow and tonight I think I am going to write a new cover letter. Let’s see what else I can get done tonight. Hmm I think I will try to do a sim of my home wireless LAN and study for CCENT test in about 3 weeks.   So see you tomorrow (I hope).

  • Going Metro

    - by Tony Davis
    When it was announced, I confess was somewhat surprised by the striking new "Metro" User Interface for Windows 8, based on Swiss typography, Bauhaus design, tiles, touches and gestures, and the new Windows Runtime (WinRT) API on which Metro apps were to be built. It all seemed to have come out of nowhere, like field mushrooms in the night and seemed quite out-of-character for a company like Microsoft, which has hung on determinedly for over twenty years to its quaint Windowing system. Many were initially puzzled by the lack of support for plug-ins in the "Metro" version of IE10, which ships with Win8, and the apparent demise of Silverlight, Microsoft's previous 'radical new framework'. Win8 signals the end of the road for Silverlight apps in the browser, but then its importance here has been waning for some time, anyway, now that HTML5 has usurped its most compelling use case, streaming video. As Shawn Wildermuth and others have noted, if you're doing enterprise, desktop development with Silverlight then nothing much changes immediately, though it seems clear that ultimately Silverlight will die off in favor of a single WPF/XAML framework that supports those technologies that were pioneered on the phones and tablets. There is a mystery here. Is Silverlight dead, or merely repurposed? The more you look at Metro, the more it seems to resemble Silverlight. A lot of the philosophies underpinning Silverlight applications, such as the fundamentally asynchronous nature of the design, have moved wholesale into Metro, along with most the Microsoft Silverlight dev team. As Simon Cooper points out, "Silverlight developers, already used to all the principles of sandboxing and separation, will have a much easier time writing Metro apps than desktop developers". Metro certainly has given the framework formerly known as Silverlight a new purpose. It has enabled Microsoft to bestow on Windows 8 a new "duality", as both a traditional desktop OS supporting 'legacy' Windows applications, and an OS that supports a new breed of application that can share functionality such as search, that understands, and can react to, the full range of gestures and screen-sizes, and has location-awareness. It's clear that Win8 is developed in the knowledge that the 'desktop computer' will soon be a very large, tilted, touch-screen monitor. Windows owes its new-found versatility to the lessons learned from Windows Phone, but it's developed for the big screen, and with full support for familiar .NET desktop apps as well as the new Metro apps. But the old mouse-driven Windows applications will soon look very passé, just as MSDOS character-mode applications did in the nineties. Cheers, Tony.

  • ROA on top of SOA

    - by Vaibhav Pujari
    I already have a stable Service Oriented Architecture for my application which exposes services as API calls. (the verbs) Now, I need to build a Resource Oriented Architecture to expose a RESTful API to interact with the application objects. (the nouns) What are the best practices to reuse the existing services: - without any persistence inside my new code. - without putting unnecessary logic into the REST layer i.e. it should ideally just leverage the services provided by SOA API. I want this layer to be as thin as possible. - without modifying the existing SOA API - allow easy extension of the REST API i.e. it should be easy to add more resources without changing the (yet to be written) core code. (I want to make resource names and their associated actions configurable so more contributors can easily add resources without a need to understand my module) Any advices/suggestions how to achieve this? Edit: Adding more info My Stack: My existing stacks is in Java. But since I plan to just use the services, I don't think that should affect the design of new REST code. I am planning to implement the new REST code in PHP. How well the services map to resources? Some services are mapped well i.e. there are services for creating, updating application objects. But for other application objects, there are no direct services available. More importantly, there are actions beyond just create, update etc. that apply to application objects. And I would like to provide some way for these actions to be exposed through REST. Since these are verbs, how do I deal with them? Where exactly I need help? I would appreciate any help towards high level design to accomplish the task along-with making the framework extendible. For instance, tomorrow there are some new services added to my SOA layer, I want to make sure it is easy for a fresh developer to write a REST call by simply registering a new resource (in a config file/db) and write code for connecting it with SOA calls. Just like plugin.

  • 8GB, but have to run Windows Xp (32 Bit). Anything I can do with the additional memory?

    - by user12889
    I ordered a new computer with 8GB RAM with the plan to run Windows 7, 64Bit. Turns out now, that I need to run a 32Bit OS (XP or 7) due to some software which does not run on 64Bit yet (not even with any of the available compatibility settings / modes). Is there anything I can do with the memory above 4GB in this scenario? I'm willing to consider creative solutions like running a hypervisor under XP that offers the memory as a RAM-Disk for swapping etc. ? The software that does not run on 64Bit is CISCO VPN (there seems to be a half-working solution for that) and CISCO IP phone / webcam integration "CISCO Unified Video Advantage" (there is apparently no solution for that).

  • Roll your own free .NET technical conference

    - by Brian Schroer
    If you can’t get to a conference, let the conference come to you! There are a ton of free recorded conference presentations online… Microsoft TechEd Let’s start with the proverbial 800 pound gorilla. Recent TechEds have recorded the majority of presentations and made them available online the next day. Check out presentations from last month’s TechEd North America 2012 or last week’s TechEd Europe 2012. If you start at http://channel9.msdn.com/Events/TechEd, you can also drill down to presentations from prior years or from other regional TechEds (Australia, New Zealand, etc.) The top presentations from my “View Queue”: Damian Edwards: Microsoft ASP.NET and the Realtime Web (SignalR) Jennifer Smith: Design for Non-Designers Scott Hunter: ASP.NET Roadmap: One ASP.NET – Web Forms, MVC, Web API, and more Daniel Roth: Building HTTP Services with ASP.NET Web API Benjamin Day: Scrum Under a Waterfall NDC The Norwegian Developer Conference site has the most interesting presentations, in my opinion. You can find the videos from the June 2012 conference at that link. The 2011 and 2010 pages have a lot of presentations that are still relevant also. My View Queue Top 5: Shay Friedman: Roslyn... hmmmm... what? Hadi Hariri: Just ‘cause it’s JavaScript, doesn’t give you a license to write rubbish Paul Betts: Introduction to Rx Greg Young: How to get productive in a project in 24 hours Michael Feathers: Deep Design Lessons ØREDEV Travelling on from Norway to Sweden... I don’t know why, but the Scandinavians seem to have this conference thing figured out. ØREDEV happens each November, and you can find videos here and here. My View Queue Top 5: Marc Gravell: Web Performance Triage Robby Ingebretsen: Fonts, Form and Function: A Primer on Digital Typography Jon Skeet: Async 101 Chris Patterson: Hacking Developer Productivity Gary Short: .NET Collections Deep Dive aspConf - The Virtual ASP.NET Conference Formerly known as “mvcConf”, this one’s a little different. It’s a conference that takes place completely on the web. The next one’s happening July 17-18, and it’s not too late to register (It’s free!). Check out the recordings from February 2011 and July 2010. It’s two years old and talks about ASP.NET MVC2, but most of it is still applicable, and Jimmy Bogard’s Put Your Controllers On a Diet presentation is the most useful technical talk I have ever seen. CodeStock Videos from the 2011 edition of this Tennessee conference are available. Presentations from last month’s 2012 conference should be available soon here. I’m looking forward to watching Matt Honeycutt’s Build Your Own Application Framework with ASP.NET MVC 3. UserGroup.tv User Group.tv was founded in January of 2011 by Shawn Weisfeld, with the mission of providing User Group content online for free. You can search by date, group, speaker and category tags. My View Queue Top 5: Sergey Rathon & Ian Henehan: UI Test Automation with Selenium Rob Vettor: The Repository Pattern Latish Seghal: The .NET Ninja’s Toolbelt Amir Rajan: Get Things Done With Dynamic ASP.NET MVC Jeffrey Richter: .NET Nuggets – Houston TechFest Keynote

  • How can I broadcast video live (preferably wirelessly)?

    - by Blixt
    Update I've gotten plenty of feedback on the software solutions and the unanimous solution for having a handheld device to record video seems to be to use a mobile phone (I was hoping there'd be some webcam-like device with wifi support...) I'd appreciate more hardware suggestions now. That is, what mobile phones have good video recording quality (and battery time)? I'm looking for a solution to broadcast video live on the internet from a location (an apartment), with a device that can be carried around. What options are there? I'm looking for complete solutions (i.e., what hardware to use, what software to use, how it should all be set up.) Currently, I have my mobile phone (Nokia N95 8GB) with Qik installed connected to wifi, but unfortunately the videos get bad quality (especially since it's indoors with poor lighting) plus the battery gets used up quickly.

  • How to manage credentials on multiserver environment

    - by rush
    I have a some software that uses its own encrypted file for password storage ( such as ftp, web and other passwords to login to external systems, there is no way to use certificates ). On each server I've several instances of this software, each instance has its own password file. At the moment number of servers is permanently growing and it's getting harder and harder to manage all passwords on all instances up to date. Unfortunately, some servers are in cegregated network and there is no access from them to some centralized storage, but it works vice versa. My first idea was to create a git repository, encrypt each password with gpg and store it there and deliver it within deployment system, but security team was not satisfied with this idea and as it is insecure to store passwords in repository even in encrypted view ( from their words ). Nothing similar comes to my mind. Is there any way to implement safe and secure password storage with minimal effort to manage all passwords up-to-date? ps. if that matters I've red hat everywhere.

  • Open Source webapp that shows PC / Projector status in 30+ Lecture rooms

    - by Seanchán
    I am looking for a simple web application that only has a simple graphical representation of the current status of 30+ lecture rooms. I.e. Green = good, Red=bad i.e. PC or Projector not working. With a little message and a ETA as well. I am not looking for monitoring software, merely a way for a tech to flag a room as "technically challenged" until 1PM or until "Friday 10AM". With a message for those lecturers who are interested: "Waiting on replacement bulb" or "Power supply gone" I know this is a simple thing to code up yourself, but I am looking for something that has been around for a few years that has some cool extra little functionality that you wouldn't think of yourself. I just can't find anything like that out there. And just to be clear: not monitoring software, more like lecturer feedback web app.

  • Why are invariants important in Computer Science

    - by Antony Thomas
    I understand 'invariant' in its literal sense. I also recognize them when I type code. But I don't think I understand the importance of this term in the context of computer science. Whenever I read conversations\white papers about language design from famous programmers\computer scientists, the term 'invariant' keeps popping up as a jargon; and that is the part I don't understand. What is so special about it?

  • Analysis Services Tabular books #ssas #tabular

    - by Marco Russo (SQLBI)
    Many people are looking for books about Analysis Services Tabular. Today there are two books available and they complement each other: Microsoft SQL Server 2012 Analysis Services: The BISM Tabular Model by Marco Russo, Alberto Ferrari and Chris Webb Applied Microsoft SQL Server 2012 Analysis Services: Tabular Modeling by Teo Lachev The book I wrote with Alberto and Chris is a complete guide to create tabular models and has a good coverage about DAX, including how to use it for enriching a semantic model with calculated columns and measures and how to use it for querying a Tabular model. In my experience, DAX as a query language is a very interesting option for custom analytical applications that requires a fast calculation engine, or simply for standard reports running in Reporting Services and accessing a Tabular model. You can freely preview the table of content and read some excerpts from the book on Safari Books Online. The book is in printing and should be shipped within mid-July, so finally it will be very soon on the shelf of all the people already preordered it! The Teo Lachev’s book, covers the full spectrum of Tabular models provided by Microsoft: starting with self-service BI, you have users creating a model with PowerPivot for Excel, publishing it to PowerPivot for SharePoint and exploring data by using Power View; then, the PowerPivot for Excel model can be imported in a Tabular model and published in Analysis Services, adding more control on the model through row-level security and partitioning, for example. Teo’s book follows a step-by-step approach describing each feature that is very good for a beginner that is new to PowerPivot and/or to BISM Tabular. If you need to get the big picture and to start using the products that are part of the new Microsoft wave of BI products, the Teo’s book is for you. After you read the book from Teo, or if you already have a certain confidence with PowerPivot or BISM Tabular and you want to go deeper about internals, best practices, design patterns in just BISM Tabular, then our book is a suggested read: it contains several chapters about DAX, includes discussions about new opportunities in data model design offered by Tabular models, and also provides examples of optimizations you can obtain in DAX and best practices in data modeling and queries. It might seem strange that an author write a review of a book that might seem to compete with his one, but in reality these two books complement each other and are not alternatives. If you have any doubt, buy both: you will be not disappointed! Moreover, Amazon usually offers you a deal to buy three books, including the Visualizing Data with Microsoft Power View, another good choice for getting all the details about Power View.

  • Apple MagicMouse randomly loses connection

    - by Yuval
    My Magic Mouse periodically randomly loses connection to my macbook, sitting approximately a foot and a half away from it. There are no software updates available for Snow Leopard (10.6.3). I have a bluetooth keyboard (that sits a little closer to the macbook, though I'm not sure this is the issue) that rarely suffers from this problem. Google results mostly suggest to update the software but I have the most updated version of it already. Does anybody have any idea what could be causing the issue? Is this simply a defective mouse? Additional info: I tried replacing the batteries with new ones, making sure they are sitting tightly in their position with no change in behavior (still disconnects periodically). Also, this doesn't seem to be a problem that the mouse is turning itself off to save battery - it does not reconnect when I move or click it. If I wait long enough (a couple of minutes) it reconnects on its own. Otherwise I have to go to the bluetooth menu with my macbook touchpad and choose "yuval's mouse - Connect"

  • Doubts about Cloud Infrastructure

    - by Pravin
    Maybe a little more of the same questions that others have asked but wanted to clarify my doubt, for some years run my hosting company (reseller of esds) and I've done well so far, but I am determined to bring quality and server technology to offer another level. So far I have understood that there is a difference between cloud and cluster servers because the cluster function as load balancers that distribute in different servers roles and use the servers less overloaded in the cloud is the union of multiple servers and then the same is vitualized unlike the cluster that is allowed to use the resources of the CPU and RAM servers in the virtualized environment. My approach is to use 3 dedicated servers to create a cloud server, My doubts: Does this type of cloud servers are only reserved for big companies? (Either because the union of the servers is done by hardware or software with high price) What characteristics should these servers meet? Possibly through software which should be used? Available? Thanks for your time, Cheers!

  • Quality Assurance & Quality Control = verification & validation?

    - by user970696
    According to a book (page below), reviewing e.g. design (verification activity) is quality assurance. I would not agree, I would say its quality control because we are checking the conformance to specification, plans and detecting deviations (defects) as we do in quality control. But what would be an example of QA then? Could you give me a clear example that proves/disproves what is this book saying? Software Testing: Srinisvasan Desikan, Gopalaswamy Ramesh

  • Port forwarding no longer works

    - by Auryn
    Prior to testing an OpenVPN installation, I setup a basic VPN server using the software already built into Windows 7. Port forwarding on the Linksys router worked as normal and I was able to connect remotely. After doing an install of OpenVPN Access Server on a spare box running Ubuntu, and adding new ports to be forwarded I was unable to access the VPN from an external source as the required ports all indicated that they were closed. (During testing XRDP and VNCSERVER were also installed to facilitate access to the box) Checking back on the Windows 7 VPN resulted in no access to that vpn setup either. All ports are now reporting a being closed despite being previously open even ports that were being used for other services. Adding and removing port forwarding rules seem to have no effect. At this point, in order to troubleshoot, both the firewall and anti-virus software have been disabled on the Windows 7 machine. Could this be just a router issue? Is there any way out of this without having to reset and reconfigure the router?

  • Random Monday Thoughs

    - by Terry Goldman
    On this Monday morning my thoughts center on why is it so hard to embrace governance, any form of governance for that matter, be it software development governance, SOA governance, data governance, IT governance, so on a so fourth?Most customers that I meet tend to think that they don't need don't need governance as all is good within the enterprise. The question I generally pose to colleges and customers, is you have to think of governance as an insurance policy. Take of instance, if you just bought a new car, perhaps your "dream" car, would you drive it on the open streets without having the car insured? Probably not.Governance is what insurance is to new cars, be it to SOA, IT transformations and software development. Governance is a insurance policy against risk of failure. Now once I put it in this context, ask yourself, does governance have value to your organization? Most people now get it. Once the seed of governance is planted at the executive level of an organization, it becomes a exercise in planting an that idea into key personnel within the organization. Then the justification for governance grows and grows across the enterprise.Thats my food for though in this Monday morning.FYI, stay tuned for an upcoming multi-part article on using Oracle Enterprise Repository to build a Enterprise Continuum as described in TOGAF v9.0.

  • How do you deal with translating theory into practice?

    - by Mr. Shickadance
    Hello all! Being a computer scientist in a research field I am often tasked with working alongside professionals outside of the software domain (think math people, electrical engineer etc), and then translating their theories and ideas into real-world implementations. I often find it difficult when they present a theoretical problem which appears to be somewhat disconnected from reality. I am not saying that the theory is bogus, only that it is difficult to translate into real-world situations. For example, recently I have been working with software defined radios. We are exploring many different areas, but often the math specialists in my group would present a problem which is heavily grounded in theory (signal processing, physics, whatever). I often struggle at times where it is hard to draw direct parallels between the theory and the real-world implementation that I need to develop. Say we are working on an energy detector, the theory person in my group would say "you need to measure the noise variance with no signal present." This leads me to think "how the hell do I isolate noise from a signal in reality?" There are many examples, but I hope you see where I am going. So, my question is how does one deal with implementation of theoretical concepts when the theory seems detached from reality? Or at least when the connections are not so clear. Or perhaps, the person with the 'theory' may be ignorant of real restrictions? Note: I found this to be a hard question to ask - hopefully you are following me. If you have suggestions on how I could improve it, by all means let me know! Thanks for looking! EDIT: To be a bit more clear, I understand in situations like this that I must learn that specific domain myself to an extent (i.e. signal processing), but I am more concerned with when those theoretical concepts do not appear to be as grounded in practice as one would like.
