• How best to look up objects by label?

  - by dsollen

  I am writing the server backed by a pre-written API. I'm going to get a number of strings representing ports, signals, paths, etc etc etc. I need to look up the object associated with a given label, these objects are all in memory (no sql magic to do this for me). My question is, how best do I associate a given unique label with the mutable object it represents? I have enough objects that looking through every signal or every port to find the one that matches is possible, but may be slightly too slow. To be honest the direct 'look at every object' method is probably good enough for so small a body of objects and anything else is premature optimization, but I still am curious what the proper solution would be if I thought my signals were going to grow a bit larger. As I see it there are two options available. First would be to to create a 'store' that is a simple map between object and label. I could have it so that every time I call addObject the object is automatically saved into a hashmap or the like. This works, but relies on my properly adding and deleting each object so the map doesn't grow indefinitely. The biggest issue to me is that this involves having some hidden static map in my ModelObject class that just feels...wrong somehow. The other option is to have some method that can interpret the labels. All of these labels are derived from the underlying objects. So I can look at the signal label, for instance, and say "these 20 characters are the port" to figure out what port I need. This would allow me to quickly figure out what I need. However, if the label method is changed the translateLabelToObject method needs to be updated as well or everything breaks. Which solution is cleaner, or possibly a cleaner solution than either of above? For the record I'm working with sufficient number of variables to make direct comparison a little slow, but not enough to be concerned about memory overhead, written in java. All objects that have labels I need to look up extend the same parent class.

• Will not supporting IE or older browsers drive away potential visitors/users of my site? [closed]

  - by XToro

  Normally a SO browser but this question doesn't fit there, hopefully it fits here. I just want to ask from web designers' point of view if it's wrong to not care about supporting Internet Explorer or older browsers. The site I'm designing looks great in all browsers except IE9-. There are certain things that IE doesn't support or behave like other browsers; webkit stuff, some CSS styles, drop-and-drop files from OS etc etc, but it all works great in Safari, FireFox, Chrome etc. Should I be that concerned? I know there are several people that use IE, but it's limitations have just been causing me more work by having to come up with workarounds. From what I've read, many of the issues I've been having should be solved with IE10, but not everybody keeps up to date. I know of several people who are still using IE6! Again, I'm hoping this is the right place to ask a question like this, and if not, please point me to the right stack exchange site instead of just downvoting me. Thanks! EDIT: Upon further research.... So far this year, IE(all versions) and Chrome have been neck and neck as the top, with IE only squeaking by Chrome, and FireFox a close 3rd. But looking at the top 10 browsers, IE6 doesn't even show up on this list in which the lowest percentage is 1.92%. Source : http://www.w3counter.com/globalstats.php?year=2012&month=7 Having a look at this other site, IE6 shows up in 11th place out of 12, just before "Other" http://www.sitepoint.com/browser-trends-february-2012/ This makes me a little more wary of not spending more time on IE compatibility. However, my site will not be going to a live beta until October or November, and I'm hoping that IE10 will have more features coded into it. Currently, I've written my upload page which is a "drag-and-drop files from the OS" type to simply display "IE is not supported", leaving no other option for IE users to upload pictures because I've spent so much time writing the uploader which does many things other than just upload the files. I will be changing this kinda cold "Access Denied" to a suggestion to upgrade, or install other browsers, with download links for each. Big thanks for the posts here and the interesting links!

• What is hiberfil.sys and How Do I Delete It?

  - by The Geek

  You’re no doubt reading this article because there’s a gigantic hiberfil.sys file sitting in the root of your drive, and you want to get rid of it to free up some space… but you can’t! Luckily, you actually can delete it, and today we’ll show you how. The more memory you have in your PC, the bigger the file will be. So What is hiberfil.sys Anyway? Windows has two power management modes that you can choose from: one is Sleep Mode, which keeps the PC running in a low power state so you can almost instantly get back to what you were working on. The other is Hibernate mode, which completely writes the memory out to the hard drive, and then powers the PC down entirely, so you can even take the battery out, put it back in, start back up, and be right back where you were. Hibernate mode uses the hiberfil.sys file to store the the current state (memory) of the PC, and since it’s managed by Windows, you can’t delete the file. So if you never use it, and want to disable Hibernate mode, keep reading. Personally I stick with Sleep Mode the vast majority of the time, but I do use Hibernate quite often. Disable Hibernate (and Delete hiberfil.sys) in Windows 7 or Vista You’ll need to open an administrator mode command prompt by right-clicking on the command prompt in the start menu, and then choosing Run as Administrator. Once you’re there, type in the following command: powercfg -h off You should immediately notice that the Hibernate option is gone from the Shut down menu. You’ll also notice that the file is magically gone! For more about dealing with Hibernate like setting how long it takes to head into Hibernate mode, you can check out our article on How to Manage Hibernate Mode in Windows 7. Disabling Hibernate Mode in Windows XP It’s a lot easier in Windows XP to get rid of Hibernate mode… in fact, we’ve already covered it before, but we’ll cover it again. Just head into Control Panel –> Power Options, and then find the Hibernate tab. Uncheck the box, reboot your PC, and then you can delete the hiberfil.sys file.

• Insert Or update (aka Replace or Upsert)

  - by Davide Mauri

  The topic is really not new but since it’s the second time in few days that I had to explain it different customers, I think it’s worth to make a post out of it. Many times developers would like to insert a new row in a table or, if the row already exists, update it with new data. MySQL has a specific statement for this action, called REPLACE: http://dev.mysql.com/doc/refman/5.0/en/replace.html or the INSERT …. ON DUPLICATE KEY UPDATE option: http://dev.mysql.com/doc/refman/5.0/en/insert-on-duplicate.html With SQL Server you can do the very same using a more standard way, using the MERGE statement, with the support of Row Constructors. Let’s say that you have this table: CREATE TABLE dbo.MyTargetTable (     id INT NOT NULL PRIMARY KEY IDENTITY,     alternate_key VARCHAR(50) UNIQUE,     col_1 INT,     col_2 INT,     col_3 INT,     col_4 INT,     col_5 INT ) GO INSERT [dbo].[MyTargetTable] VALUES ('GUQNH', 10, 100, 1000, 10000, 100000), ('UJAHL', 20, 200, 2000, 20000, 200000), ('YKXVW', 30, 300, 3000, 30000, 300000), ('SXMOJ', 40, 400, 4000, 40000, 400000), ('JTPGM', 50, 500, 5000, 50000, 500000), ('ZITKS', 60, 600, 6000, 60000, 600000), ('GGEYD', 70, 700, 7000, 70000, 700000), ('UFXMS', 80, 800, 8000, 80000, 800000), ('BNGGP', 90, 900, 9000, 90000, 900000), ('AMUKO', 100, 1000, 10000, 100000, 1000000) GO If you want to insert or update a row, you can just do that: MERGE INTO     dbo.MyTargetTable T USING     (SELECT * FROM (VALUES ('ZITKS', 61, 601, 6001, 60001, 600001)) Dummy(alternate_key, col_1, col_2, col_3, col_4, col_5)) S ON     T.alternate_key = S.alternate_key WHEN     NOT MATCHED THEN     INSERT VALUES (alternate_key, col_1, col_2, col_3, col_4, col_5) WHEN     MATCHED AND T.col_1 != S.col_1 THEN     UPDATE SET         T.col_1 = S.col_1,         T.col_2 = S.col_2,         T.col_3 = S.col_3,         T.col_4 = S.col_4,         T.col_5 = S.col_5 ; If you want to insert/update more than one row at once, you can super-charge the idea using Table-Value Parameters, that you can just send from your .NET application. Easy, powerful and effective

• ETPM Forms Accelerator

  - by MHundal

  The ETPM Forms Accelerator provides a template that can be used to enter data related to Registration and Tax Forms.  The Forms Accelerator includes a worksheet for each portion related to forms development (Form Type, Form Section, Form Lines and Form Rules).  The Forms Accelerator provides the details that must be defined in ETPM.  This allows for taking an existing form and translating the details of that form into the spreadsheet.  The spreadsheet can then be used to define the details in the system.  In addition, each of the items to be defined is explained it detail - what the field expects and based on the input, how it impacts the field and form definition.   This is a living document - as there is feedback provided, the document will be updated.  The goal of this accelerator is to be an aide in the Forms Development process.  We encourage feedback to help improve the document.  The document is for ETPM 2.3.1.  Implementations using older version of ETPM will find that some of the field definition options may not exist their current system.   The spreadsheet attached contains the following Worksheets: Instructions:  High-level overview for the different worksheets provided. Form Type:  The fields to be populated when defining the Form Type for a Registration or Tax Form Form Section:  The fields to be populated when creating a Form Section.  The number of sections will differ based on the the form being implemented. Form Lines:  The fields to be populated when creating different Form Lines. The number of lines per section will differ based on the form being implemented. Form Rules:  Based on the form, allows for documenting the Form Rules to be configured based on form instructions and Form Lines.

• Ubuntu 12.04 - PPTP VPN is the only Internet Access

  - by user212553

  I know this has been covered. I've read dozens of posts but still have questions. I have a work server whose traffic should never leave my house without encryption. The VPN is PPTP. Currently I have a cron job that checks the status of the ppp0 adapter each minute. If the connection drops, which it does fairly often, it shuts key components down. It's fairly easy to restart PPTP with "nmcli con up id 'myVPNServer'" but there's no assurance it will reconnect and I need a better way to stop traffic (other than killing apps) when ppp0 is down. The two options I've seen discussed are the firewall (UFW, Firestarter, IPTables) or the route tables. I could be easily swayed to consider the firewall option but I focused on the route tables since no new function needs to be started. My questions involve the way the route tables change and then specifics on rules. When I start the PPTP VPN the route tables change. That suggests that if the VPN drops, the table will change back, defeating my stated intent of preventing external traffic. How can I make "sticky" changes to the route table that will persist even if the VPN connection drops? Perhaps the check boxes "Ignore automatically obtained routes" or "Use this connection only for resources on it's network" (which are part of the VPN configuration options)? It would seem that, if I can force the active VPN route table to stay in effect, even when the VPN drops, that this will effectively kill any external traffic should the VPN drop. This will give me the latitude to run a routine to restart the VPN from the command line (assuming the route table rules don't prevent me re-establishing the connection). My route table, with the VPN active is (ip route list): Any comments on what 10.10.1.1 is? $ ip route list default dev ppp0 proto static 10.10.1.1 dev ppp0 proto kernel scope link src 10.10.1.11 VPN_Server_IP_Address via 192.168.1.1 dev eth0 proto static VPN_Server_IP_Address via 192.168.1.1 dev eth0 src 192.168.1.60 169.254.0.0/16 dev eth0 scope link metric 1000 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.60 metric 1

• [EF + Oracle] Inserting Data (Sequences) (2/2)

  - by JTorrecilla

  Prologue In the previous chapter we have see how to create DB records with EF, now we are going to Some Questions about Oracle.   ORACLE One characteristic from SQL Server that differs from Oracle is “Identity”. To all that has not worked with SQL Server, this property, that applies to Integer Columns, lets indicate that there is auto increment columns, by that way it will be filled automatically, without writing it on the insert statement. In EF with SQL Server, the properties whose match with Identity columns, will be filled after invoking SaveChanges method. In Oracle DB, there is no Identity Property, but there is something similar. Sequences Sequences are DB objects, that allow to create auto increment, but there are not related directly to a Table. The syntax is as follows: name, min value, max value and begin value. 1: CREATE SEQUENCE nombre_secuencia 2: INCREMENT BY numero_incremento 3: START WITH numero_por_el_que_empezara 4: MAXVALUE valor_maximo | NOMAXVALUE 5: MINVALUE valor_minimo | NOMINVALUE 6: CYCLE | NOCYCLE 7: ORDER | NOORDER 8:    How to get sequence value? To obtain the next val from the sequence: 1: SELECT nb_secuencia.Nextval 2: From Dual Due to there is no direct way to indicate that a column is related to a sequence, there is several ways to imitate the behavior: Use a Trigger (DB), Use Stored Procedures or Functions(…) or my particularly option. EF model, only, imports Table Objects, Stored Procedures or Functions, but not sequences. By that, I decide to create my own extension Method to invoke Next Val from a sequence: 1: public static class EFSequence 2: { 3: public static int GetNextValue(this ObjectContext contexto, string SequenceName) 4: { 5: string Connection = ConfigurationManager.ConnectionStrings["JTorrecillaEntities2"].ConnectionString; 6: Connection=Connection.Substring(Connection.IndexOf(@"connection string=")+19); 7: Connection = Connection.Remove(Connection.Length - 1, 1); 8: using (IDbConnection con = new Oracle.DataAccess.Client.OracleConnection(Connection)) 9: { 10: using (IDbCommand cmd = con.CreateCommand()) 11: { 12: con.Open(); 13: cmd.CommandText = String.Format("Select {0}.nextval from DUAL", SequenceName); 14: return Convert.ToInt32(cmd.ExecuteScalar()); 15: } 16: } 17:  18: } 19: } This Object Context’s extension method are going to invoke a query with the Sequence indicated by parameter. It takes the connection strings from the App settings, removing the meta data, that was created by VS when generated the EF model. And then, returns the next value from the Sequence. The next value of a Sequence is unique, by that, when some concurrent users are going to create records in the DB using the sequence will not get duplicates. This is my own implementation, I know that it could be several ways to do and better ways. If I find any other way, I promise to post it. To use the example is needed to add a reference to the Oracle (ODP.NET) dll.

• Optionally Running SPSecurity.RunWithElevatedPrivileges with Delgates

  - by Damon Armstrong

  I was writing some SharePoint code today where I needed to give people the option of running some code with elevated permission.  When you run code in an elevated fashion it normally looks like this: SPSecurity.RunWithElevatedPrivileges(()=> {     //Code to run }); It wasn’t a lot of code so I was initially inclined to do something horrible like this: public void SomeMethod(bool runElevated) {     if(runElevated)     {         SPSecurity.RunWithElevatedPrivileges(()=>         {             //Code to run         });     }     else     {         //Copy of code to run     } } Easy enough, but I did not want to draw the ire of my coworkers for employing the CTRL+C CTRL+V design pattern.  Extracting the code into a whole new method would have been overkill because it was a pretty brief piece of code.  But then I thought, hey, wait, I’m basically just running a delegate, so why not define the delegate once and run it either in an elevated context or stand alone, which resulted in this version which I think is much cleaner because the code is only defined once and it didn’t require a bunch of extra lines of code to define a method: public void SomeMethod(bool runElevated) {     var code = new SPSecurity.CodeToRunElevated(()=>     {         //Code to run     });     if(runElevated)     {         SPSecurity.RunWithElevatedPermissions(code);         }     else     {         Code();     } }

• Problem with DualBooting Ubuntu 13.10 and Win7

  - by VinArrow

  this is my first post here on AskUbuntu, not first time using it though. I wanted to install Ubuntu 13.10 on my PC to have all my work stuff there and leave Win7 for gaming. So i did my research on how to Dual Boot when you already have Win7 installed, here are the steps i took Used Disk Management on Win7 and shrunk that partition, leaving 80GB free for Ubuntu. Made a Bootable pendrive following the instructions on Ubuntu`s website. During the installation steps there was supposed to be a Install alongside Win7, but there wasnt, so i chose Something else. Everything was fine and i was able to install Ubuntu no problem on my unallocated 80GB partition (76GB Ubuntu + 4GB swap) There was a prompt for me to restart my PC and so I did expecting to see the dual boot screen (grub right?) Now, when i restarted my PC, Grub never showed up and it booted straight to Windows. Then I did some more research and found out that that could happen. Tried three things then Plugging in bootable pendrive again and selected Try Ubuntu without installing. Then i followed some instructions found here (How can I repair grub? (How to get Ubuntu back after installing Windows?)) and i could chroot into my Ubuntu install just fine. Repaired grub as instructed on that link, restarted the PC and booted straight into Win7 again. Again, used the bootable pen drive to Try Ubuntu... and used the Boot-repair tool (recommended repair). Again, booted straight into Win7. Lastly, i installed easyBCD on my Win7 and made a new entry for Ubuntu (Linux/BSD). When i rebooted the PC, there was the option to choose between Win7 and Linux, chose linux and it didnt work, taking me straight to a command line-like enviroment that read Minimum bash like scripting or something, as if I didn`t have a Linux OS installed. So, I thought I`d try and repair my Ubuntu install. And during the Installation method step there was the choice to install alongside Ubuntu 13.10! and that right there drove me crazy. Here is a screenshot of gparted showing how things are set up now http://imageshack.us/f/801/77u3.png/ Notice on the left-hand side how i can access my installation files just fine. sdb1- win7 reserved space, sdb2- win7 OS, sdb3- 76GB ubuntu install, sdb5- 4GB swap area. Does anyone know why my Ubuntu 13.10 is not being recognized? and what should I do to get it working? Thanks and sorry for the long read and bad english! (BIOS = legacy)

• From 20,663 issues to 1 issue&ndash;style-copping C5.Tests

  - by TATWORTH

  Originally posted on: http://geekswithblogs.net/TATWORTH/archive/2014/05/28/from-20663-issues-to-1-issuendashstyle-copping-c5.tests.aspxI recently became interested in the potential of the C5 Collections solution from http://www.itu.dk/research/c5/, however I was dismayed at the state of the code in the unit test project, so I set about fixing the 20,663 issues detected by StyleCop. The tools I used were the latest versions of: My 64-bit development PC running Windows 8 Update with 8Gb RAM Visual Studio 2013 Ultimate with SP2 ReSharper GhostDoc Pro My first attempt had to be abandoned due to collision of class names which broke one of the unit tests. So being aware of this duplication of class names, I started again and planned to prepend the class names with the namespace name. In some cases I additionally prepended the item of the C5 collection that was being tested. So what was the condition of code at the start? Besides the sprawl of C# code not written to style cop standard, there was: 1) Placing of many classes within one physical file. 2) Namespace within name space that did not follow the project structure. 3) As already mentioned, duplication of class names across namespaces. 4) A copyright notice that spawled but had to be preserved. 5) Project sub-folders were all lower case instead of initial letter capitalised. The first step was to add a stylecop heading plus the original heading contained within a region, to every file. The next step was to run GhostDoc Pro using its “Document File” option on every file but not letting it replace the headers, I had added. This brought the number of issues down to 18,192. I then went through each file collapsing each class and prepending names as appropriate. At each step, I saved the changes to my local Git. The step was to move each class to its own file and to style-cop each file. ReSharper provides a very useful feature for doing this which also fixes missing “this.” and moves using statements inside the namespace. Some classes required minimal work whereas others required extensive work to reach the stylecop standard. The unit tests were run at each split and when each class was completed. When all was done, one issue remained which I will need to submit to stylecop team for their advice (and possibly a fix to stylecop). The updated solution has been made available at https://c5stylecopped.codeplex.com/releases/view/122785.

• ODEE Green Field (Windows) Part 2 - WebLogic

  - by AndyL-Oracle

  Welcome back to the next installment on how to install Oracle Documaker Enterprise Edition onto a green field environment! In my previous post, I went over some basic introductory information and we installed the Oracle database. Hopefully you've completed that step successfully, and we're ready to move on - so let's dive in! For this installment, we'll be installing WebLogic 10.3.6, which is a prerequisite for ODEE 12.3 and 12.2. Prior to installing the WebLogic application server, verify that you have met the software prerequisites. Review the documentation – specifically you need to make sure that you have the appropriate JDK installed. There are advisories if you are using JDK 1.7. These instructions assume you are using JDK 1.6, which is available here. The first order of business is to unzip the installation package into a directory location. This procedure should create a single file, wls1036_generic.jar. Navigate to and execute this file by double-clicking it. This should launch the installer. Depending on your User Account Control rights you may need to approve running the setup application. Once the installer application opens, click Next. Select your Middleware Home. This should be within your ORACLE_HOME. The default is probably fine. Click Next. Uncheck the Email option. Click Yes. Click Next. Click Yes Click Yes and Yes again (yes, it’s quite circular). Check that you wish to remain uninformed and click Continue. Click Custom and Next. Uncheck Evaluation Database and Coherence, then click Next. Select the appropriate JDK. This should be a 64-bit JDK if you’re running a 64-bit OS. You may need to browse to locate the appropriate JAVA_HOME location. Check the JDK and click Next. Verify the installation directory and click Next. Click Next. Allow the installation to progress… Uncheck Run Quickstart and click Done.  And that's it! It's all quite painless - so let's proceed on to set up SOA Suite, shall we?

• IPv6, isn't it just a few extra bits?

  - by rclewis

  It's always an interesting task, to try and explain what you do to family and friends. I have described IPv6 as the "Next Generation Internet"  or "Second Internet" but the hollow expressions on my kids faces scream for the instant relief of the latest video game.  Never one to give up easily, I have formulated a new example - the Post Office... Similar to the Post Office the Internet delivers mail and packages based on addresses. As the number of residences, businesses, and delivery locations increased, the 5 digit ZIP Code (Washington, DC 20005) was expanded to ZIP+4  allowing for more precise delivery points (Postmaster General, Washington, DC 20260-3100). Ah, if only computers were as simple.  IPv6 isn't an add-on or expansion of the existing IPv4 Addressing, it is a new addressing model which will allow the internet to grow from a single computer in the basement of a university or your parents kitchen table, to support the multitude of smart phones, smart TV's, tablets, dvr's, and disk players, all clambering to connect for information. Unfortunetly there are only a finite number of IPv4 public addresses left, and those are being consumed at an ever increasing rate. Few people could have predicted the explosive growth of the internet or the shortage of IPv4 addresses we now face - but there is a "Plan B" and that is the vastly larger address space of IPv6.  Many in the industry have labeled this a "business continuity" problem,  when in fact most companies will be able to continue conducting business once they run out of existing IPv4 Addresses. The problem is really a Customer Continuity problem, how will businesses communicate with existing customers and reach new customers online who's only option is to adopt IPv6 when IPv4 is depleted? Perhaps a first step is publishing a blog that is also accessible via IPv6, it's just a few extra bits. Join us for the Oracle OpenWorld 2012 Session:   Navigating IPv6 @ Oracle Thursday, Oct. 4th 2:15PM - 3:15PM  Palace Hotel - Concert   Learn more about IPv6 Technologies at Oracle

• dual boot ubuntu installation mishap

  - by user590849

  I have Windows 7 pc ,where i had 2 partitions, a c drive for my system files and a d drive for my data. I decided to install ubuntu 11.10 a couple of days ago and thought of install it in a separate partition of its own. So i made a separate Linux partition of 30GB. I downloaded ubuntu on my usb stick and installed. During the installation process i was asked where to install ubuntu so i opened up a screen that was similar to this one There were six partitions present ( I had made only 3 partition via windows). Their names were totally different from the ones that i had given in windows. So i selected a drive which had the same size as my Linux partition that i had made in windows ( no other partition had the same size). I clicked on install now and got an error message saying that "There was no root folder set". I set the newly made partition as my root folder and clicked install now. Now out of the 6 partitions that were created 3 were logical ( i had only created 3 partitions in windows). As soon as i clicked install now, the system asked me where i wanted to put my "swap space". I selected one of the logical drives and hit install. Ubuntu successfully installed on my system and at the end it asked me to reboot. I did and got the following error message: "missing operating system". I was shocked. I tried my windows recovery disk ( that i had gotten when i had purchased my laptop) and there i went into startup repair. In the startup repair option i was not able to locate windows. The system asked me to click the "Load drivers" button to load the drivers to my harddrive where windows was installed, but i could not locate any drivers to my harddrive. I tried this several times but to no success. I panicked and installed ubuntu, now this time click "ok" at every step( not worrying about the partition and all). The os installed correctly and i am now able to access my harddrive. NO data within the c drive is lost. All the windows system files are intact. I wish to recover my windows installation. How do i go about it? Thank you in advance. I do not want to format my computer and install windows again.

• Integrating with a payment provider; Proper and robust OOP approach

  - by ExternalUse

  History We are currently using a so called redirect model for our online payments (where you send the payer to a payment gateway, where he inputs his payment details - the gateway will then return him to a success/failure callback page). That's easy and straight-forward, but unfortunately quite inconvenient and at times confusing for our customers (leaving the site, changing their credit card details with an additional login on another site etc). Intention & Problem description We are now intending to switch to an integrated approach using an exchange of XML requests and responses. My problem is on how to cater with all (or rather most) of the things that may happen during processing - bearing in mind that normally simplicity is robust whereas complexity is fragile. Examples User abort: The user inputs Credit Card details and hits submit. An XML message to the provider's gateway is sent and waiting for response. The user hits "stop" in his browser or closes the window. ignore_user_abort() in PHP may be an option - but is that reliable? might it be better to redirect the user to a "please wait"-page, that in turn opens an AJAX or other request to the actual processor that does not rely on the connection? Database goes away sounds over-complicated, but with e.g. a webserver in the States and a DB in the UK, it has happened and will happen again: User clicks together his order, payment request has been sent to the provider but the response cannot be stored in the database. What approach could I use, using PHP to sort of start an SQL like "Transaction" that only at the very end gets committed or rolled back, depending on the individual steps? Should then neither commit or roll back have happened, I could sort of "lock" the user to prevent him from paying again or to improperly account for payments - but how? And what else do I need to consider technically? None of the integration examples of e.g. Worldpay, Realex or SagePay offer any insight, and neither Google or my search terms were good enough to find somebody else's thoughts on this. Thank you very much for any insight on how you would approach this!

• Need Help with partitions and such Dual Booting 13.10 w/ windows 7

  - by Aymax

  so I've spent the past couple days freaking out about this and looking for answers, and I decided to resort to asking on forums. probably should have before I wasted 2 entire days. so I am trying to DUAL-INSTALL Ubuntu 13.10 with my x64 Windows 7 home premium computer. I have 6 gb of ram, 1TB hard drive, and a 3.3GHZ dual core processer (just in case it matters). I've managed to figure some things out. I've burned the ubuntu files onto a DVD, and I have been able to successfully run it off the disk. I also shrunk my Windows partition by 120Gb and partitioned that for Ubuntu (all using the windows Disk Manager). Problems: When I turn my computer on with the DVD in the tray, the computer cant find windows. it flashes a screen real quick that says something about not being able to find an operating system, and then goes to "grub" and asks what i want to do with Ubuntu. this scares me, because I don't know if that means that I will not be able to boot windows if I install Ubuntu. The Ubuntu 13.10 installer does not detect my Windows operating system. I only have the options to Erase everything on my drive, or "something else." I choose that, which brings me to 3 I don't understand the partition table. I have no idea which drive im selecting to install stuff on, much less which one to select. I tried to tell by the amount of memory partitioned off, but none of the numbers seem to be accurate. Plus, all the names are dev/sda(#). I know Ubuntu knows the name of my partition, because on the sidebars it shows the names of the different drives, including the partition I made; so why don't they use the names? I have no idea what I'm going to be erasing. I've read that I should know which is which by the file system type, but they are all NTFS, including the one I made. my only other option was FAT, none for EXT2 or any of that like people said to do. My main concerns are that of accidentally erasing windows or not being able to access windows. any feasible solution is helpful, weather it helps me with the install or to make Ubuntu see windows. I realize this question has been asked much, but i have found no feasible answers so far. I am relatively new to this, and have never installed an operating system before, so I do not know most of the jargon. please keep it relatively simple, please. I am not a programmer. Thanks.

• Laptop freezes and seems to crash, but continues working after waiting for a few minutes [closed]

  - by Corwin

  I've had this old notebook laying around and because i was missing a second machine (My wife usually steals the first ;) ) I considered installing Linux. As a php developer I work with Linux servers (usually fedora) on a daily basis and because its an older machine that I want to use for development, linux seemed the best option. Speedwise I expected a good experience, better than Windows 7 on the same machine. The results where terrible. I tried ubuntu 12.04. The shell never got past showing the background. The system doesn't freeze since the mouse still works and I can use ctrl+alt+f2 etc to enter terminal mode. I expected hardware problems en even exchanged the harddisk en Ram memory. No luck though, so I started over and tried 11.10 Same results so I tried 10.04.4 which did install properly. Not sure if unity was the problem, but it seems likely. But then I tried simply things like surfing on the net, the system frooze and I thought it crashed so after a few minutes I pulled the plug and rebooted. But it happened again and I waited. After a few minutes the system came back to life like nothing happened. Long story short. Besides the fact that the entire interface is very sluggish, any and all graphical functions freezes the system. The more elaborate the animation would be, the longer it freezes. I switch chromium from window to fullscreenmode and had to wait 15 minutes to continue. I don't see the animation that's probably supposed to be in between. It just freezes and then after unfreezing its fullscreen. I don't think its a bug. I suspect the problem is with my graphics card. Like I said, its and old system. So old that I can't even find the original Ati drivers anywere. (I'll post the details of my system at the end of my post) I'm at a loss as to what to do next. I tried other Distro's. So far only dreamlinux works normally. Linux Mint won't start as a live CD. I think I simply need a driver update but I can't find them anywhere. Does anyone have the same experience ? Maybe even someone who has or had the same notebook running Ubuntu at some point ? Anyway, here are the specs: http://www.nec-driver.com/nec-driver/NEC-Versa-P550---FP550-Driver_421.html

• laptop will not boot after attempting upgrade to 13.10

  - by naerwenya

  I wanted to update my OS to the new 14.04 LTS. I was running 12.04 LTS before and followed the advice that upgrades should be done in steps. I first upgraded to 12.10, which seemed to work fine, and later to 13.10. This was all done through the Software Manager. After the last upgrade, I am no longer able to boot up my computer. The GNU GRUB menu opens up, but after selecting Ubuntu, it just stalls with a blank purple screen. If I select one of the other kernels, it also stalls after "Loading initial ramdisk...". I can't get into the Recovery Menu, either. I'm still rather new to Linux and may have possibly made the situation worse. Unfortunately, nothing has worked yet. I tried reinstalling from a flash drive and on my first attempt, the wizard recognised a previous installation. Unfortunately, the wizard also didn't like how my partitions were set up (I didn't change anything) and gave an error before closing. Unfortunately, I didn't write the error down, but it was about the boot partition. On the next attempt and ever since, the installation wizard has stated that "This computer currently has no detected operating systems." This is strange, because I could see the disk and even access my files when booting up from the USB. At this point, I decided to back up my important files using dropbox. Before losing all my files, I wanted to try the Boot-Repair tool, which also produced no results, and the files are no longer visible when booting from USB. The link to the Boot-Repair log is at http://paste.ubuntu.com/7457249/. If I then proceed through to the "Something else" installation option, I can see that the partitions still exist. This is what they look like: /dev/sda free space (size indicated 1MB) /dev/sda1 efi (33MB of 98 MB used) /dev/sda2 efi (352634MB of 746330MB used) /dev/sda3 swap (3725MB, none used) free space (0MB) Is there any way I might be able to get my computer to work and preserve my files as well?

• Windows 7 pro remote desktop true multi monitor support patch or hack

  - by Ryan D

  After hours of research the closest i came to any patch that could fix this was a concurrent sessions patch which is not what i want. I have two machines both windows 7 professional. Its not an option to upgrade either to ultimate as the computer being remoted is in another state at our corp office. I need Dual monitor support and would have used the multimon i:1 edit thing however the other tower is not Win 7 ultimate. I have read over and over how it is not supported except with ultimate and enterprise and 2008 server. What have they put into windows 7 ultimate that is not in Win 7 pro and how can i get it or patch Win 7 pro to give it the same functionality. I would have paid for a software patch had i been able to find it anywhere. Summary: I am looking for the ability to remote to a Win 7 pro computer with another Win 7 computer while being able to use Dual monitors. Is there anyone that has the skill or balls to help with this? Most Respectfully Ryan

• Windows 2012/IIS 8 + ASP.NET MVC Applicaiton 403.14 (Forbidden) - The Web server is configured to not list the contents

  - by WiredPrairie

  I have a very simple MVC 4 application I'm trying to deploy to a Windows 2012 server. Inconsistently, when navigating to the root of the web application (http://localhost/app), it returns a 403.14-Forbidden: Detailed Error Information: Module: DirectoryListingModule Notification: ExecuteRequestHandler Handler: StaticFile Error Code: 0x00000000 Requested URL: http://localhost:80/test1/ Physical Path: c:\apps\test1\ Logon Method: Negotiate The web application is: Is a very vanilla VS2012 MVC4 Intranet template -- with only a tweak to a label to prove things were working. runs in an Integrated v4.0 application pool setup to use Windows authentication application pool has a custom AD Identity assigned (so it can gain access to a SQL server) application pool identity has read permissions in the c:\apps\test1 folder in which it is running It's an MVC4 application, targeting .NET 4.0 currently -There's no default document in an MVC4 application (like a default.aspx), as there shouldn't need to be one. I don't want to enable directory listings (as that's not the real error).

The reason I say it's inconsistent is that I've seen it work, then I've published, and the error returns. I can't find a pattern to the issue (and right now, I haven't been able to get it work again, at all). The 403 is returned from a local or remote web browser. I've had trouble finding a solution that isn't intended for older versions of Windows (like suggestions to reinstall ASP.NET which won't work on Windows 2012). I really don't know what else to try.

• Powerpoint missing from DCOM config

  - by Paul Prewett

  I have an application that automates the creation of powerpoint files in an ASP.NET environment. This requires that I install powerpoint on the server and also set permissions in the DCOM configuration snap-in (dcomcnfg) to give permissions to the launching user ([DOMAIN]\ASPNET in this case) to run the application. I have this setup running successfully on several Win2k3 machines. I am configuring my first Win2k8 machine and after installing powerpoint on the server, the "Microsoft Powerpoint Presentation" node in DCOM config is not showing up. Other installed Office apps are showing (Excel, Graph, etc...), just not Powerpoint. So when I attempt to run the application, I get an "Access denied" error, which is exactly what I would expect. The user doesn't have permission. Therefore, access denied. The specific error log entry is: The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID {91493441-5A91-11CF-8700-00AA0060263B} to the user [DOMAIN]\ASPNET I searched the entire list for the CLSID, too, thinking maybe the name wasn't loading properly. No dice. I also re-ran the setup program for Office thinking maybe there would be some option or something I unchecked in the custom setup options, but I saw nothing that looked helpful. I'm flummoxed. Can anyone out there suggest something to help me get Powerpoint to show up in the list of DCOM applications? Many thanks.

• RouterOS on Hyper-V (v3/2012) - any way to get it working?

  - by TomTom

  Trying to set up a small VPN point to connect into a remote Hyper-V cluster using ROuterOS. Anyone got it working ON Hyper-V with the latest builds of RouterOS? It seems the legacy network adapter is not supported anymore either (or just broken). The platform is a Windows Server 2012 RC. This is not a high performance setup - the RouterOS wont do the routing for more than the backend administrative access, and the only real traffic we will see there is when ISO images for new operating systems are uploaded. Otherwise we will have possibly RDP traffic as well as web / http traffioc, but this is internal only (dashboards, some control panel). The server has no public business. So the price for non virtualized network cards is ok for me. After hooking up - ping just does not work. After some time I see in windows (arp -a on the command line), so I know that the Hyper-V side is set up properly. Just no packets arrived. I have turned off all protection on Hyper-V (or : not turned them on), so no MAC spoofing protection etc. in the Advanced page for the legacy adapters. Unless I can get it work I will have to resort to using a windows install as router / VPN endpoint, which introduces another OS into the fabric (we run all routers etc. so far on mikrotik in hardware, which is why I want this one to be RouterOS, too). And no, putting hardware there is NOT an option - the cost would be significant.

• Telling subversion client to ignore certificate errors

  - by Pekka

  I have set up a copy of Redmine through the Bitnami Redmine Stack and am having trouble accessing a remote SVN repository through https. The trouble seems to be related to the fact that I don't have a signed certificate, and the certificate provided doesn't match the host name (I am accessing the same server through a number of host names). I am new to Ruby, Mongrel, Rails and Redmine. Following the advice in this forum thread, I changed the path Redmine uses to invoke the svn client in \apps\redmine\lib\ redmine\scm\adapters\subversion_adapter.rb from SVN_BIN = "svn" to SVN_BIN = "svn --trust-server-cert --non-interactive --config-dir c:/user/temp" I was hoping that the --trust-server-cert option would fix the certificate problem. However, I am still getting the following error message in mongrel.log: svn: OPTIONS of 'https://server.xyz:8443/svn/reponame': Server certificate verification failed: certificate issued for a different hostname, issuer is not trusted (https://server.xyz:8443) Does anybody know what to do about this? Additional info: I re-started the mongrel service after each change I am sure the configuration change has taken effect because subversion has created a full configuration directory in c:\user\temp I can access the remote repository using command line svn no problem The remote repository runs on a Windows box with VisualSVN

• Routing static IP traffic on a Comcast Business Class IP Gateway (SMCD3G-CCR)

  - by Jakobud

  We are in the process of replacing our firewall, which is currently the only thing connected to our Comcast Business Class modem. Comcast gives us 5 static IP addresses. Currently, all traffic to all 5 static IPs goes directly to the existing firewall. Eventually, obviously all traffic will goto the new firewall, once the old firewall is removed from the network. But in the meantime, as we will have two firewalls plugged into the same Comcast modem, I need to route certain traffic to the new firewall instead of the old one. The firewall switchover is going to be slow and gradual as I am testing it, so I can't simply unplug the existing firewall and plug in the new one. So my question is, how do I tell the modem to route all traffic that goes to a specific IP to goto the new firewall instead of the old one? I've logged into the web interface for the modem, but the available options aren't very clear. There is a 1-to-1 NAT option (which I can't seem to get the interface for it to work properly) but I also see a "Static Routing" section. I always understood Static Routing to refer to routing data within the LAN though, so I'm not sure if that's what I'm looking for or not. Keep in mind, I'm not looking to do simple port forwarding. I'm wanting 100% of traffic to certain public static IPs to go to the specified connected firewall (I'll deal with service policies there). The modem is an SMC SMCD3G-CCR and is labeled as a Comcast Business Class Business IP Gateway. Any help or direction would be greatly appreciated.
