  • Using Enums for comparing string values in Switch

    - by kaleidoscope
    Problem Scenario: There is an enum keeping track of operations to be performed on a table Public Enum PartitionKey { Createtask, Updatetask, Deletetask } User is entering the value for the operation to be performed and the code to check the value entered in switch case. Switch (value) {           case PartitionKey.Createtask.ToString():          {          Create();          break;          }          case PartitionKey.Updatetask.ToString():          {           Update();           break;          }          case PartitionKey.Deletetask.ToString():          {           Delete();          break;          } } and it displays as error as “.” Solution: One of the possible implmentation is as below. Public Enum PartitionKey: byte { Createtask, Updatetask, Deletetask } Switch ((PartitionKey)(Int32.Parse(value))) {          case PartitionKey.Createtask:          {                   Create();                   break;          }          case PartitionKey.Updatetask:          {                    Update();                   break;          }          case PartitionKey.Deletetask:          {                    Delete();                   break;          }          default:          {                   break;          } } Technorati Tags: Enum,A Constant Value is required,Geeta,C#

  • Why is Prolog associated with Natural Language Processing?

    - by kyphos
    I have recently started learning about NLP with python, and NLP seems to be based mostly on statistics/machine-learning. What does a logic programming language bring to the table with respect to NLP? Is the declarative nature of prolog used to define grammars? Is it used to define associations between words? That is, somehow mine logical relationships between words (this I imagine would be pretty hard to do)? Any examples of what prolog uniquely brings to NLP would be highly appreciated.

  • Petites tables ou grandes tables... Quelles conséquences sur les performances des bases de données ? par SQLpro

    Bonjour, La plupart des développeurs sont persuadés que mettre toutes les informations dans une même table rendra leur base de données plus rapide... Et l'on voit apparaître dans la base de nombreuses tables de plusieurs dizaines de colonnes. C'est une vue à court terme, car dés que la base de données commence à croitre ou que le nombre d'utilisateur augmente, les performances deviennent vite catastrophique...

  • Automatic Statistics Update Slows Down SQL Server 2005

    I have a database which has several tables that have very heavy write operations. These table are very large and some are over a hundred gigabytes. I noticed performance of this database is getting slower and after some investigation we suspect that the Auto Update Statistics function is causing a performance degradation.

  • Allow members of a group to be unlocked by a specific account on AD

    - by JohnLBevan
    Background I'm creating a service to allow support staff to enable their firecall accounts out of hours (i.e. if there's an issue in the night and we can't get hold of someone with admin rights, another member of the support team can enable their personal firecall account on AD, which has previously been setup with admin rights). This service also logs a reason for the change, alerts key people, and a bunch of other bits to ensure that this change of access is audited / so we can ensure these temporary admin rights are used in the proper way. To do this I need the service account which my service runs under to have permissions to enable users on active directory. Ideally I'd like to lock this down so that the service account can only enable/disable users in a particular AD security group. Question How do you grant access to an account to enable/disable users who are members of a particular security group in AD? Backup Question If it's not possible to do this by security group, is there a suitable alternative? i.e. could it be done by OU, or would it be best to write a script to loop through all members of the security group and update the permissions on the objects (firecall accounts) themselves? Thanks in advance.

  • Is it viable to become a contract programmer straight out of college?

    - by M G
    I have a Bachelor of Science in Computer Science and four months research experience designing and implementing a research project. I realize this is highly dependent on my skill set - which includes C, C++, Java, Python, and SQL. I feel I have an advantage in two ways: I am young and am not afraid to work overtime. I am willing to take lower pay to gather a client base/experience, and work nights/weekends to get a few projects under my belt. This may be cliche, but I feel that I can learn new technologies quicker than most. At the very least, I am not a slow study. With this being said, is it viable for me to become a contract programmer? Or do I need the 10+ year skill set that most contractors bring to the table?

  • DVD/CD burning .zip: is it more reliable, faster, longer lasting to burn a zip of files rather than the files as a folder?

    - by Rob
    Is it more reliable, faster, longer lasting to burn to CD/DVD a zip (or a few large zips) of files rather than the files as a folder? Just thinking if 1000s of small files would not be as efficiently recorded compared with one or a few large zips. Also, even after the burning program verifies the disc, I also use Beyond Compare to compare the files with those on the disc. Always binary compares as identical but I hear the drive stuttering presumably as the head is being shifted only slightly each time to seek the next file, which leads me to think that its best to make one or more zips and copy those locally to compare. Or is it that burning invidual files to the disc is not as readable which causes the head to stutter. There aren't any problems, my disc burns are reliable, just thinking more of efficiency and longevity, the discs burn and verify fast enough on my 18x DVD burner. I'm using ImgBurn mostly. Also used Nero in the past. I burn whole discs closed, finalised. Not sure which write mode but would think Disc At Once from a temporary cached image made by the burning program would be the most reliable.

  • Routing WIFI and LAN for specific traffic

    - by jakebird451
    I have two network devices aboard my macbook pro: WIFI (en1): Used for general traffic. Connects to an ip of 192.168.19.* via DHCP LAN (en0): Used for specific traffic. Connects to an ip of 192.168.2.10 as a static IP. Does not connect to a router, only a switch for direct routing connection. I have 4 IP addresses I need to access on the LAN: 192.168.2.1 192.168.2.21 192.168.2.20 192.168.2.30 The rest of the traffic needs to go to WIFI. I have tried setting up a routing table for the specific ip addresses, but I only managed to mess up my network. I do not venture out into the world of networking too often, but this was the latest command I have been trying: sudo route add -host 192.168.2.30 -interface en0 This command killed my ability to use ping. It told me that ping could not allocate memory (is that even possible)? It also killed my wifi access. Logging out and back in fixed the issue. I really do not mind to make this solution permanent, so I am fine with a temporary routing.

  • Passing class names or objects?

    - by nischayn22
    I have a switch statement switch ( $id ) { case 'abc': return 'Animal'; case 'xyz': return 'Human'; //many more } I am returning class names,and use them to call some of their static functions using call_user_func(). Instead I can also create a object of that class, return that and then call the static function from that object as $object::method($param) switch ( $id ) { case 'abc': return new Animal; case 'xyz': return new Human; //many more } Which way is efficient? To make this question broader : I have classes that have mostly all static methods right now, putting them into classes is kind of a grouping idea here (for example the DB table structure of Animal is given by class Animal and so for Human class). I need to access many functions from these classes so the switch needs to give me access to the class

  • Windows Server 2008 R2 Standard to Enterprise Problems

    - by boburob
    A few months ago I setup a Citrix XenApp cluster running on Windows Server 2008 R2 Standard Edition using the temporary 180 day license key. Recently the company bought a Windows Server 2008 R2 Enterprise DataCenter license. This means I need to upgrade the Windows edition from Standard to Enterprise. I attach the disk to the VM and start the upgrade process through XenCenter, it runs through all checks and unpacks all Windows files and seems to create a Windows Setup partition, it then reboots and trys to boot into this partition and I get a blue screen telling me to CHKDSK the hard drive with the following error message: STOP: 0x0000007B As XenApp is already setup and working I really do not want to go down the route of rebuilding this server (as I already had to do this once down to issues with XenApp). The server did have 8GB of RAM assigned to it, I have tried reducing this down to 2GB's as I read this can cause an issue. Also I can boot back into the Windows Server 2008 R2 Standard partition without any problems. UPDATE I have managed to get round the urgency by re-arming the license, giving me another 180 day trial..but would be nice to work out why this is happening!

At the beginning you think it’s easy, but when it’s your turn, you realize that actually it’s not as easy as you thought it would be. Especially nowadays, when we’re living difficult times and finding a job is a challenge. This is why I felt lucky when I joined Oracle. Do you want to know how did I do it? My name is Markéta Kocová and I am working as a Customer Intelligence Support Intern within Oracle Prague. Before this job I have, I was focused on my studies, going also abroad for one semester in Rostock University in Germany. I decided though to gain some working experience. In November 2011, I joined Oracle, this one being my first job. I never thought I would be part of such a big company, but here I am! I have to say that I think it’s quite difficult to find a job and thus job search might be exhausting. What did help me? I think it was the networking. The more people you know, the more chances you have to find a job. This is how I’ve heard about this internship. I think internship programs are a great opportunity for young people to gain experience and also to start building a career. As companies are looking for the candidates with the best skills and some experience, it’s difficult to get a job. It’s a paradox isn’t it? You are applying for a entry-level position, but you won’t get it because they’ll be searching for someone who has experience. This is why internship is a good solution to improve your skills. You will learn many things, you might get a mentor and also perform given tasks. What else could you do? In my opinion you should invest in yourself. Try to focus on both education and skills. In order to get a good job in an international and successful company, it’s not enough a university diploma. You could learn a foreign language because it’s usually required. Employers are also looking for good computer skills, so this could be something you could take into consideration before applying to a job. There are also some personal characteristics like communication abilities, self-reliance, self-confidence or ability to solve the crisis situations that companies look at when hiring a person. You could consider attending some training in order to improve these soft skills. Getting a job is difficult, but also when you make it and get one you’ll still finding challenging to stay there. You might realize it is not the dream job, but being patient and trying to learn as much as possible will help you to achieve more. I think every experience is valuable. I’ve been through this type of situation, but the environment, my colleagues and the atmosphere in office have always been great and made me love my job! Thanks guys!

  • Can Windows Media Player create playlists based on folder structure?

    - by Chaulky
    Over the years I've carefully molded my digital media collection into a series of folders that make it easy for me to find what I'm looking for. I recently discovered the awesomeness that is streaming video from Windows 7 Media Player to the PS3 so I can watch it on the big screen without all the hassle of hooking the computer up to the TV. The problem is, I totally lose my carefully crafted folder structure and all my videos become one giant mess again... not cool! As a temporary solution, I've created a few playlists for my favorites (Dexter Season 4, Dexter Season 5, Breaking Bad Season 1, etc.). This is a HUGE pain in the a$$. So, is there a way to get Windows Media Player (on Windows 7) to maintain some sort of folder structure based on the location of the actual video files? So if I have my videos sorted into folders by show and season, Media Player will pick that up and let me browse it in the same way. As an alternative answer, I'll accept suggestions for a program that can also stream to PS3 and has this "folder organization" feature.

  • cPanel FTP account access to sym links from parent directory

    - by totbar
    I would like to give a potential developer temporary access to some of my projects. I have almost everything in its own subdomain, and each directory is a sibling to my public_html directory. It looks something like: ("developer" is the cPanel account name.) developer/ *This is the top level directory for the cPanel account. "/home/developer" site1/ *site1.mysite.com site2/ *site2.mysite.com site3/ *site3.mysite.com public_html/ *www.mysite.com ... etc I created a directory inside public_html called tempdev and I added symbolic links to each of the sibling directories listed above. My understanding of cPanel is that I can only assign one user with "Special FTP Access" per domain. I really dont want to give a complete stranger my login creds, (its just a development environment but still). So I used the cPanel FTP account creator UI. It will not allow me to assign the user access to the directories outside of public_html. I cant even give access to public_html either. So I made the tempdev directory in www and created the symlinks. Using the new account, I can see the symlinks, but I can go into them. Is there a better way to accomplish what I am attempting?

  • Connect USB hard drive to wireless router on RJ45 port? Possible?

    - by lawphotog
    just a quick story behind. I was trying to set up wireless networked hard drive at home. My wireless router doesn't take USB. I am considering few options. First i was considering to get something like WD My Cloud. My router is an old one provided by service provider. It only has 10/100 Ethernet. WD My Cloud has Gigabit interface. So unless i changed a new router, data transfer will be slow. So upgrading the router is a must if i want fast transfer speed. Plus I already own an external hard drive with USB 3.0 interface. So if I get a router like Netgear D6300, i can get a decent speed wireless shared drive at home. And i can use my existing HDD instead of WD My Cloud. But the router isn't cheap so I am saving up for that. In the meantime I found out the existence of USB to RJ45 adaptor. I read the reviews and some say it works for them and for some don't. They didn't really say what they were trying to do so I'm confused. So if i bought an adaptor like this, can i connect my existing HDD (USB) with my existing router (RJ45) and use it as a shared drive for data transfer? I know it will be slow as the adaptor will only have USB 2.0 and 10/100 for Ethernet. But it's fine as it's for temporary until i got my new router.

  • Updating files with a Perforce trigger before submit [migrated]

    - by phantom-99w
    I understand that this question has, in essence, already been asked, but that question did not have an unequivocal answer, so please bear with me. Background: In my company, we use Perforce submission numbers as part of our versioning. Regardless of whether this is a correct method or not, that is how things are. Currently, many developers do separate submissions for code and documentation: first the code and then the documentation to update the client-facing docs with what the new version numbers should be. I would like to streamline this process. My thoughts are as follows: create a Perforce trigger (which runs on the server side) which scans the submitted documentation files (such as .txt) for a unique term (such as #####PERFORCE##CHANGELIST##NUMBER###ROFL###LOL###WHATEVER#####) and then replaces it with the value of what the change list would be when submitted. I already know how to determine this value. What I cannot figure out, is how or where to update the files. I have already determined that using the change-content trigger (whether possible or not), which "fire[s] after changelist creation and file transfer, but prior to committing the submit to the database", is the way to go. At this point the files need to exist somewhere on the server. How do I determine the (temporary?) location of these files from within, say, a Python script so that I can update or sed to replace the placeholder value with the intended value? The online documentation for Perforce which I have found so far have not been very explicit on whether this is possible or how the mechanics of a submission at this stage would work.

  • Products missing from backend after import

    - by byronyasgur
    My client imported about 70 products into magneto and the all imported properly it seemed, but now only about half of them appear in the catalog ( backend ) searching for the SKU returns no results. I have searched the net for an hour looking for some information on this but I cant find any, furthermore I cant seem to find out how to verify whether the products are in the database or not, I thought I could just look for the products table in phpmyadmin, but Magento's EAV database structure looks more complicated than I'm used to. Does anyone know how to fix this, or even to locate products in the database. Edit : From talking to the client she thinks that this might have happened after she did a reindex.

  • How much isometric sprites can one optimize by mirroring and alike?

    - by Tom
    I am working on a basic isometric game, and am struggling to find the correct mirrors. I have managed to get SE out of SW, by scaling the sprite on X axis by -1. Same applies for NE angle. Something is bugging me, that I should be able to also mirror N to S, but I cannot manage to pull this one off. Am I just too sleepy and trying to do the impossible, or a basic -1 scale on Y axis is not enough? What are the common used mirror table for optimizing 8 angle (N, NE, E, SE, S, SW, W, NW) isometric sprites?

In the box where I should be able to choose a partition, none are available to choose from, it is blank. I know that HP has decided to use 4 partitions. How do I go about deleting all the partitions using the LiveCD? I've never used GParted before and am a bit lost when it comes to anything to do with partitions.

  • Two Values Enter, One Value Leaves

    - by Bunch
    This is a fairly easy way to compare values for two different controls. In this example a user needs to enter in a street address and zip code OR pick a county. After that the application will display location(s) based on the value. The application only wants a specific street/zip combination or a county, not both. This code shows how to check for that on an ASP.Net page using some JavaScript. The control code: <table>     <tr>         <td>             <label style="color: Red;">Required Fields</label>         </td>         <td style="width: 300px;">             <label style="color: Red; font-weight: bold;" id="reqAlert" ></label>         </td>     </tr>     <tr>         <td>             <asp:Label ID="Label3" runat="server" Text="Street Address"></asp:Label>         </td>         <td style="width: 200px;">             <input id="Street" type="text" style="width: 200px;" />         </td>     </tr>      <tr>         <td>             <asp:Label ID="Label5" runat="server" Text="Zip Code"></asp:Label>             &nbsp;         </td>         <td style="width: 200px;">             <input id="Zip" type="text" style="width: 200px;"/>         </td>     </tr>     <tr>         <td>             <label style="color: Red; font-size: large;">-- OR --</label>         </td>     </tr>     <tr>         <td>             <asp:Label ID="Label2" runat="server" Text="County"></asp:Label>         </td>         <td style="width: 200px;">             <asp:DropDownList ID="ddlCounty" runat="server">                 <asp:ListItem Value="0" Text="" />                 <asp:ListItem Value="1" Text="County A" />                 <asp:ListItem Value="2" Text="County B" />                 <asp:ListItem Value="3" Text="County C" />                                </asp:DropDownList>         </td>     </tr> </table> <input id="btnMapSearch" type="button" value="Search" onclick="requiredVal()" class="actionButton" /> The onclick for the button runs the requiredVal javascript function. That is where the checks take place. If only one item (street/zip or county) has been entered the application will carry on with it’s locateAddr function; otherwise it will show an error message in the label reqAlert. The javascript: function requiredVal() {     var street = document.getElementById("Street").value;     var zip = document.getElementById("Zip").value;     var countyDdl = document.getElementById("ctl00_Content_ddlCounty");     var county = countyDdl.options[countyDdl.selectedIndex].text;     var reqAlert = document.getElementById("reqAlert");     reqAlert.innerHTML = '';   //clears out any previous messages     if (street != '' || zip != '') {         if (county != '') {             reqAlert.innerHTML = 'Please select only one required option';  //values for both were entered         }         else {             locateAddr();         }     }     else if (street == '' && zip == '' && county == '') {         reqAlert.innerHTML = 'Please select a required option';  //no values entered     }     else {         locateAddr();     } } Technorati Tags: ASP.Net,JavaScript

  • Emails not arriving to client's inbox. Server not on black list.

    - by EBroker
    Hi, I'm sending emails to my clients who are hosted on GoDaddy for both their website and email. For some reason, my system's emails are no longer reaching their inbox. My email server sends them alerts when an action is completed. These alerts are posted in my system and my email server is sending these out, but there are no bounceback emails. There have been no issues in the past year, but in the past two weeks the problem started cropping up. My clients were forced to switched to a web-based email provider like Gmail, Hotmail, Yahoo to receive their alerts. This is a temporary solution that works in the interim. I contacted GoDaddy and they are indicating that I am not being blocked. I also have a GoDaddy account and can confirm that my alerts aren't arriving in the inbox regardless of whatever safe sender items I employ in the webmail interface. I even switched all the system's outbound emails to Plain Text, no luck. Can anyone provide some insight and point me in the right direction? Thank you in advance.

  • Question regarding drives

    - by user205934
    I am a new Ubuntu user who has spent a lot of time on Windows. A very common practice for me on Windows was making two drives, C: and D: , storing installs/files in C:, and I used D: for backup or if I downloaded something that I wanted to save, I saved in D: When installing Ubuntu, it asked me if I wanted to replace Windows 7. I thought it would install Ubuntu on C: but instead it used the whole partition, nevertheless I recovered my backup using testdisk. What I wanted to do was to create a similar backup drive on Linux too. My current partition table: sda 8:0 0 232.9G 0 disk +-sda1 8:1 0 230.9G 0 part / +-sda2 8:2 0 1K 0 part +-sda5 8:5 0 2G 0 part [SWAP] sr0 11:0 1 1024M 0 rom So should I use Gparted to create another sda3 and store my important data on that? Also my current sda2 is listed as an extended partition, should I delete it? It's a very small partition, just 1K.
