• Using VMware's ESXi, can I plug in 30 USB Wireless adapters and allow each of 30 VMs one?

  - by 31eee384

  I'm assuming ESXi will act very similarly to VMware Workstation or other products, so answers based on knowledge of those programs might also help. I want to plug in 30 USB Wireless or Ethernet adapters into my server, and let each VM access one and only one of these devices. Unfortunately, I don't have the hardware to just try it out as the purchase of hubs and adapters hinges on the result of this question. The answer could be a resounding "yes, easy!" and that would be great. I couldn't find any answers to this question with google, and it's possible that this is because it's so easy to do. Thanks!

• Opportunities in Cloud Computing

  - by Paul Sorensen

  A recent article from CIO Journal indicates that there is an extreme labor shortage (in certain technology areas) that is is leading to upward pressure on wages for IT Workers. This represents a great opportunity for those with certain skill-sets, among which include Java (Oracle certification is mentioned specifically). The article points out that a key driver of the labor shortage is the expansion of cloud computing. Cloud computing is set up to make life extremely simple for end-users, but the model pushes the complexity to back-end systems which are sophisticated, enterprise-level computing stacks (Oracle has an extensive set of cloud computing solutions). These complex systems require very highly-skilled IT professionals (the best-of-the-best) to successfully develop, implement, administer and maintain them. What this mean for you is that there is opportunity for those who have the appropriate skills at the appropriate levels. If you want to be a part of this opportunity you should do a self-assessment of your own skill-sets and experience. Based upon your results you can decide where it would be most appropriate to spend your time and resources for the highest return on your investment. By expanding and sharpening your skills and by gaining greater experience you will be better prepared to take advantage of career opportunities (like this) that come along periodically. As you evaluate your needs remember that Oracle University has a tremendous selection of high-quality eduction offerings (including training and certification) that can you help move your career forward. Thanks and best of luck!

• Working for Web using open-source Technologies

  - by anirudha

  As a Web Developer we all have own dream to make a great web application. a great application was built upon high discipline and best practice on the process of development then we can make modification easier in future as if we want. the user feedback also have a matter because they tell us what they want or expected with the application we make day and night. sometime they report a nice story , experience or a problem they got with our application. so that's matter because they telling about our application much more because they use our software and a part of process of future development or next version of application we make. so the Web have a good thing that they updated as soon as possible. in desktop application their is a numbers of trouble client have when they want to use our application. first thing that installation of software never goes right on every system. big company spent a big amount of money to troble these problem the user have with their software.   Web application is nice implementation of application because their is no trouble with installation all have same experience and if something goes wrong patch come soon and no waiting for new version. Chrome even a desktop application [browser] but they automatically update themselves so their is no trouble for user to get next version now hasseles.    Web application development in Microsoft way have their own rule , pattern practice to make better application in less time. the technologies i want to show you here is some great opensource example like MySQL jQuery and ASP.NET MVC a framework based on ASP.NET server side language.   For going to next step we need to show you a list of software you need to have to fully experience this tutorial.   Visual Web Developer 2010 Express Edition  MySQL [open-source RDBMS]   Query [open-source javascript library]   for getting these software you need to pay nothing.   Visual Web Developer can obtained from Microsoft.com/Express or if you are student or Web Developer you are eligible to get the Visual studio professional and many other great software from Microsoft through their Dreamspark or WebsiteSpark programmes.   MySQL is a great Relational Database management software who are freely available from MySQL.com as a database monitorting tool you can use MySQL workbrench who can be freely get from MySQL official website or many other free tool are available for begining development with MySQL   jQuery is a great library for making javascipt development easier and faster.you can obtained jQuery from jQuery.com their official website.

• Finding the best practice for a game simulating tool

  - by Tougheart

  I'm studying Java right now, and I'm thinking of this tool as my practice project. The game is "League of Legends" in case anyone knows it, I'm not actually simulating the game as in simulating game play, I'm just trying to create a tool that can compare different champions to each other based on their own abilities and items bought inside the game. The game basics are: Every player has a champion in a team of 5 players playing against another team. Each champion has a different set of abilities (usually 4) that s/he uses to do damage to opposing champions. Each champion gets stronger by buying different items, increasing the attack it deals or decreasing the damage received. What I want to do is to create a tool to be used outside the game enabling players to try out different builds for their champions and compare the figures against other champions they usually fight against. The goal is to enable players get a deeper understanding of the different item combinations (builds) that can be used during the games, instead of trying them out in real games which can be somehow very time consuming. What I'm stuck at is the best practice I should follow to make this possible using Java, I can't figure out which classes should inherit from which, should I make champions and items specs in the code or extracted from other files, specially that I'm talking about hundreds of items and champions to use in that tool. I'm self studying Java, and I don't have much practice at it, so I would really appreciate any broad guidelines regarding this, and sorry if my question doesn't fit here, I tried to follow the rules. English isn't my native language, so I'm really sorry if I wasn't clear enough, I would be more than happy to explain anything that's not understood.

• Find possible variations of one item out of multiple baskets.

  - by tugberk

  I have three baskets of balls and each of them has 10 balls which have the following numbers: Basket 1: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 Basket 2: 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 Basket 3: 21, 22, 23, 24, 25, 26, 27, 28, 29, 30 What would be the possible variations If I were to pick one ball from each basket? I guess this is called as Probability in Mathematics but not sure. How would you write this code in C# (or any other programming language) to get the correct results? Edit: Based on @Kilian Foth's comment, here is the solution in C#: class Program { static void Main(string[] args) { IEnumerable<string> basket1 = new List<string> { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10" }; IEnumerable<string> basket2 = new List<string> { "11", "12", "13", "14", "15", "16", "17", "18", "19", "20" }; IEnumerable<string> basket3 = new List<string> { "21", "22", "23", "24", "25", "26", "27", "28", "29", "30" }; foreach (var item1 in basket1) foreach (var item2 in basket2) foreach (var item3 in basket3) { Console.WriteLine("{0}, {1}, {2}", item1, item2, item3); } Console.ReadLine(); } }

• How to choose an open source, Asterisk friendly firewall?

  - by Lucas

  I'm in pain. We are moving to a SIP based VOIP system and for whatever reason, we could not get our hosted Asterisk solution to work with our Sonicwall. Our VOIP provider gave up and is recommending an open source vendor, pfSense. A little background: We have about 30 users in our network. We use a few IPSec VPN connections for remote networks. I would like, but don't need, application layer filtering. We're active internet users, so properly traffic shaping is probably a concern. How can I tell if an open source firewall will handle VOIP setup smoothly with a hosted Asterisk system?

• Does lshw list the "factory" speed of a memory module or the effective speed and how to find the former?

  - by Panayiotis Karabassis

  I hope I phrased this correctly. lshw gives: description: DIMM Synchronous 400 MHz (2.5 ns) product: M378B5773CH0-CH9 vendor: Samsung physical id: 0 slot: DIMM0 size: 2GiB width: 64 bits clock: 400MHz (2.5ns) And indeed the memory speed is set is set to 800MHz in the BIOS, which I think makes sense since it is a double rate. On the other hand, Googling strongly suggests that to this product number corresponds the PC3-10600 type, which is 1333MHz, not 800MHz. And this seems to be confirmed in the BIOS, where if I select Auto for memory bus speed, 1333MHz is selected "based on SPD settings". However in the latter case, the computer does not boot, i.e. the kernel panics, complaining that something attempted to kill the Idle process. So, I am I am beginning to suspect that I have been given defective memory, the technician that installed saw this, and lowered the bus speed. Is this a possibility?

  I have domain accounts that I have created as contacts in another trusted domain so that they can see them in their Exchange GAL. I need a way to extract the phone number field from UserA (user account) in DomainA and import it into UserA (contact) in DomainB. I get the logic, it's just the code (vbscript/powershell/whatever) that eludes me. The logic as I see it: Connect to source AD (ou/subtree) Extract user accounts from OU and subcontainers including first name, last name, display name, and phone number Connect to target AD (ou/subtree) Verify/match contact with extract in #2 above based on display name Update phone field with phone number in extract Write log of success and failures Anybody able to help?

• Remote file copy util (like rsync) but that will take account of data already copied (in this sessio

  - by Rory McCann

  Let's say I have a directory with 2 files, both are identical and quite large (e.g. 2GB ea.) I want to rsync that directory to a remote host. As I understand it (and I could be wrong), rsync calculates checksums of files. Surely if it sees 2 files with the same checksum it can just copy the first file, then do a local copy on the remote host for the 2nd file? That would make it faster, no? On a similar note, doesn't rsync hash all the remote files before copying? If it saw a different file with the same hash as a file that was to transfered, it could do a local copy on the remote host. Does rsync support this sort of thing? Is there some way to turn it on? Is there a tool similar to rsync that will do this sort of 'hash based' local copies?

• Shuttle FB51 mobo does not boot with external USB drive attached [closed]

  - by user127236

  I am repurposing an old Alienware desktop as a home media server. The PC is based on the Shuttle FB51 motherboard. The BIOS is a Phoenix Version 6.00 PG, release date 12/16/2002. I have loaded Ubuntu 12.04 LTS on the internal hard drive. I am using a Western Digital WD Elements 1.5 TB USB 2.0 Desktop External Hard Drive for media storage. When the external drive is plugged in and the PC is powered on, it freezes very early in the BIOS self-test, even before it begins the memory test. If I unplug the drive, the self-test proceeds without further problems. I can plug the USB drive back in when the self-test is complete, and Ubuntu will boot and find the external drive normally. I've tried several changes to the BIOS setup without finding a cure for the boot issue. Any assistance gratefully accepted. JGB

• For how long do I need to store the logs?

  - by mindas

  I will soon be running an internet-based public service which will physically be hosted in the UK on a virtual server. The virtual server is provided by the ISP. I was wondering if there is/are any legal requirement(s) to keep access logs, and if yes - for how long? There is a Wikipedia article that touches this subject but I'm afraid my brain just can't grasp the legislative gibberish. I believe there's EU law and there's UK law; and I do need to comply to both, right? Can somebody explain this in pure layman's terms?

• Access Control Service: Programmatically Accessing Identity Provider Information and Redirect URLs

  - by Your DisplayName here!

  In my last post I showed you that different redirect URLs trigger different response behaviors in ACS. Where did I actually get these URLs from? The answer is simple – I asked ACS ;) ACS publishes a JSON encoded feed that contains information about all registered identity providers, their display names, logos and URLs. With that information you can easily write a discovery client which, at the very heart, does this: public void GetAsync(string protocol) {     var url = string.Format( "https://{0}.{1}/v2/metadata/IdentityProviders.js?protocol={2}&realm={3}&version=1.0",         AcsNamespace,         "accesscontrol.windows.net",         protocol,         Realm);     _client.DownloadStringAsync(new Uri(url)); } The protocol can be one of these two values: wsfederation or javascriptnotify. Based on that value, the returned JSON will contain the URLs for either the redirect or notify method. Now with the help of some JSON serializer you can turn that information into CLR objects and display them in some sort of selection dialog. The next post will have a demo and source code.

• How to change color of a cell in one sheet if its value increases or decreases from another cell value in a different sheet

  - by Sean Coffey

  I am putting together a workbook with 52 sheets for the weeks in the year. In this workbook there are multiple columns for percentages on each sheet. I want to be able to change the color of each cell based on whethernit increases (green) or decreases (red) from the same cell in the previous sheet. I have the formula i.e. =IF(ISERROR(B4/D4),"0", B4/D4) to calculate my percentages but I don't know how to put the reference in for this change. Any help?

• Client Side Prediction for a Look Vector

  - by Mike Sawayda

  So I am making a first person networked shooter. I am working on client-side prediction where I am predicting player position and look vectors client-side based on input messages received from the server. Right now I am only worried about the look vectors though. I am receiving the correct look vector from the server about 20 times per second and I am checking that against the look vector that I have client side. I want to interpolate the clients look vector towards the correct one that is server side over a period of time. Therefore no matter how far you are away from the servers look vector you will interpolate to it over the same amount of time. Ex. if you were 10 degrees off it would take the same amount of time as if you were 2 degrees off to be correctly lined up with the server copy. My code looks something like this but the problem is that the amount that you are changing the clients copy gets infinitesimally small so you will actually never reach the servers copy. This is because I am always calculating the difference and only moving by a percentage of that every frame. Does anyone have any suggestions on how to interpolate towards the servers copy correctly? if(rotationDiffY > ClientSideAttributes::minRotation) { if(serverRotY > clientRotY) { playerObjects[i]->collisionObject->rotation.y += (rotationDiffY * deltaTime); } else { playerObjects[i]->collisionObject->rotation.y -= (rotationDiffY deltaTime); } }

• Can I redeploy Citrix Xencenter Images in Amazon EC2?

  - by Mike Pinch

  Okay - I'm running Citrix Xencenter in my datacenter. My understanding is that Amazon EC2 is a very customized flavor of Xencenter. Based on that, I would like to know whether there is a method to utilize the .VHD disk images generated by Citrix Xencenter in the Amazon EC2 cloud. I realize that I can install tools into the OS and make my own images but that is not what I'm looking for. I'd like the efficiency of taking the images and redeploying them, or at least converting then redeploying. I basically would like to have all my backups running in the cloud, so that is my motivation.

• Xen Disk Performence Issues

  - by user98651

  I'm currently using Xen PV on CentOS 5 with my domU's as flat files running on a hardware RAID controlled (write cache enabled) formatted with XFS. On the dom0 I can get about 500MB/s in a 2GB dd write from /dev/zero however on the domU's I'm lucky if I get 10MB/s (it is usually around half that). I've tried changing the disk scheduling to NOOP on the domU's, changed some mount parameters and tweaked the performance allocations of both the dom0 (prioritize CPU) and domU's (increase RAM and VCPU allocations). None of these steps have produced any noticeable change in performance. My instinct here is that it is not a hardware problem, due to the solid performance of the dom0. Any ideas on what might be causing this problem? I'm considering moving to LVM based domU's.

• How to refactor to cleaner version of maintaing states of the widget

  - by George

  Backstory I inherited a bunch of code that I'd like to refactor. It is a UI application written in javascript. Current state: We have main application which consist of several UI components. And each component has entry fields, textboxes, menus, etc), like "ticket", "customer information", etc. Based on input, where the application was called from, who is the user, we enable/disable, hide, show, change titles. Unfortunately, the app grew to the point where it is really hard to scale, add new features. Main the driver (application code) calls set/unset functions of the respective components. So a lot of the stuff look like this Main app unit function1() { **call_function2()** component1.setX(true); component1.setY(true); component2.setX(false); } call_function2() { // it may repeat some of the code function1 called } and we have a lot of this in the main union. I am cleaning this mess. What is the best way to maintain the state of widgets? Please let me know if you need me to clarify.

• Dropping the full-time high-pay gig - I need help choosing a smart path that I can rely on to produce enough to survive comfortably ($2,500 per month)

  - by Jeff V

  I have about 6 years of full time experience developing web applications and tools. I know perl, python, PHP, ruby, and a good deal of SQL and relational theory. I have never had to choose a self-employed path as I have always had full time work or a bank account (credit cards) to support a big project. I'm planning to move out of the country to an area that will not offer local employment, and need some advice on what to focus on. I want to move in no more than six months, I have enough savings to live for an additional six months, but I would like to conserve it as much as possible. I enjoy taking risks, so I'm not looking for discussion of whether this is a good idea or not. I want advice on the most reliable solution given my skill set. Some paths I'm considering: Learn objective-c and build quality Apple software. Develop subscription based web tools for SEO, or other Marketing applications Attempt to acquire freelance projects by developing a reputation within open source projects, freelancer.com, and other online communities The last time I left my job, I was building a startup (that went under), and missed out living in a beautiful place due to the amount of time I worked. I would like to work 30-40 hours per week max. I can dedicate 10-15 hours per week while at my current job to prepare and learn. A preemptive thanks for the advice...

• Needing to concatenate between cells that change daily. I want to be able to automate this vs manual

  - by Harold

  I use concatenate to pull data together from different cells in my spreadsheet. Since my data changes daily, I want the formula to also change daily without having to manually input the new cell in the concatenate formula. I am looking for a way to do this but not sure how. Can anyone out there help me out please!? I appreciate the assistance in advance! Maybe this will help to explain what I need. I have a row of data from D4:AH4 that I insert daily based on the new day. When I use the concatenate and us the following formula: =CONCATENATE(TEXT('Raw Data'!B4,"m/d")," ",TEXT('Raw Data'!C4,"")," ",TEXT('Raw Data'!E4,"0.0%"))... E4 being the cell that changes daily where next day would be F4, G4, etc... All other parts of the formula will stay the same. I hope this helps! Thanks! :)

• How to appear very professional on my first freelance project?

  - by iamserious

  I need some help on appearing very professional on my first freelance project. How / What should you do to achieve this? Background: I started as a full time web developer 18 months ago, two promotions later I am now a senior software engineer. I've never had any problems with designing / developing / coding a complicated system. I thought I could use some help for Christmas and I started bidding for a project and now I have one - from a very reputable lawyers association in London. I have no problem dealing with the actual implementation of the system, but I have no idea how to appear professional throughout the whole process. About the project: This lawyers association are starting a distant training courses and in addition to having a website to show off all their clients etc, they want a students area where their students would log in, download course materials allocated to them etc.. and an admin section where they assign courses to students / create new ones / upload materials etc.. Questions breakdown: 1) How should I start with the requirement gathering? Is using scrum a good idea, or should I use something like Volere Template - and what should I do with it? should I submit a copy to the client etc.. 2) How often should I meet the client? Would once a fortnight would be good? 3) What are the processes / protocols that I need to follow so that they would be satisfied with me and think that I am very professional 4) How much should I charge for the product? 5) How should I get a quote / contract / receipt for the whole project? 6) What are the steps that professional freelancers go through, during the life cycle of a project? My Research so far Looking at How much should I charge doesn't help.. I live in London, zone 1, though I have no idea how much a project of this size would cost. Help on this would be appreciated. How to be professional articles talks about the work / time management etc and not the actual process, what would real people do etc.. it's like academia theory, but not practical. If this needs revising, please let me know, do not close it because of whatever reason, I will edit the question or details to fit the needs. Thanks for reading a lengthy question.

• Developing with Oracle ADF Mobile and ADF Business Components Backend

  - by Shay Shmeltzer

  It's great to finally have the Oracle ADF Mobile solution out there. If you are not familiar with ADF Mobile - it basically lets you build applications that run on iOS and Android devices using the concepts you already know - components based UI constructions (same idea as JSF), taskflows, data controls, Java and of course JDeveloper. I created one demo that shows how to build an on-device application that gets data from local Java files (that run on the device - yes we do Java on iOS too) - you can see it here. However, one thing many of you might be wondering is how can you get data from your database into these mobile applications. Well if you already built your data access with Oracle ADF Business Components then here is a two step video demo that shows you what to do. The steps are: 1. Expose ADF Business Components as Services 2. Create an ADF Mobile application that consumes the above services with the Web service data control Simple right? That's the whole point of ADF Mobile - making on device application development as simple as possible. Try it out on your device.

• Anemic Domain Model, Business Logic and DataMapper (PHP)

  - by sunwukung

  I've implemented a rudimentary ORM layer based on DataMapper (I don't want to use a full blown ORM like Propel/Doctrine - for anything beyond simple fetch/save ops I prefer to access the data directly layer using a SQL abstraction layer). Following the DataMapper pattern, I've endeavoured to keep all persistence operations in the Mapper - including the location of related entities. My Entities have access to their Mapper, although I try not to call Mapper logic from the Entity interface (although this would be simple enough). The result is: // get a mapper and produce an entity $ProductMapper = $di->get('product_mapper'); $Product = $ProductMapper->find('[email protected]','email'); //.. mutaute some values.. save $ProductMapper->save($Product) // uses __get to trigger relation acquisition $Manufacturer = $Product->manufacturer; I've read some articles regarding the concept of an Anemic Domain model, i.e. a Model that does not contain any "business logic". When demonstrating the sort of business logic ideally suited to a Domain Model, however, acquiring related data items is a common example. Therefore I wanted to ask this question: Is persistence logic appropriate in Domain Model objects?

• Good practices when optimizing HTML5/Javascript Game Developement [closed]

  - by hustlerinc

  I'm just starting out as a game developer and have created a few crappy but playable clones of classic games like pong, and bomberman. Being self taught (bless the internet) I do this by just stuffing in code to make the games work. Now I feel the time has come to create something complete, for this I need to know how a game is structured. I've searched on the web but there isn't that much to be found. The only "high-level" language I know is javascript so reading a tutorial or article based on C++ doesn't help me that much. I'm looking for good resource's pedagogically covering the theory and possibly examples (in Javascript or pseudo code that is understandable for a beginner) of how the game pieces fit together. From the start screen to asset loading and running the game loop. I'm not looking for anything complicated like reading through a 4000 line source code. All I want to learn is where, how and when the main parts of every game should be called. If you know any good resources to share, or maybe even have an answer for me I would deeply appreciate it.

• Using DNS entries to determine location

  - by Raphink

  I'm trying to think of a clean way to determine the location of machines (mainly, which datacenter they belong to) based on their network settings. I would like it to be dynamic, and I'm thinking of using special DNS records that would be specific to the DNS server in each datacenter. For example, you could have: root@machine1# dig TXT mysite ... mysite 3600 IN TXT "DC1" ... root@machine2# dig TXT mysite ... mysite 3600 IN TXT "DC2" ... etc. I know that DNS has a special LOC record for location, but it takes coordinates, so it doesn't help in my case. Is there a standard way of addressing this issue, another special type of record for it, or some standard entries in TXT records?
