• how do you spend your day? a day from a programmer's life [closed]

  - by RBA

  First of all I'm 26 and I'm asking this question because I want to see how do you manage your time. Also I'm interested how do the programmers with a family(wife, several kids) manage their time. I'm asking this due the fact that I'm working aprox 7,5 hours at work (9 to 5), spent 1,5 hours on the way to/from workplace, and when I'm home I must cook/clean/etc and LEARN! And I have the impression that I don't have enough time to learn. Did you have a period similar in your life? To want to learn another language/improve your development/other skills? I saw here and on SO that there are a lot of peoples with +10k points, this in my mind means that they stay on blogs/forums more than 15 hours a day. If you consider this question is a good question, please vote to reopen it. best regards, Radu

• How to properly document functionality in an agile project?

  - by RoboShop

  So recently, we've just finished the first phase of our project. We used agile with fortnightly sprints. And whilst the application turned out well, we're now turning our eyes on some of the maintenance tasks. One maintenance task is that all of our documentation appears in the form of specs. These specs describe 1 or more stories and generally are a body of work which a few devs could knock over in a week. For development, that works really well - every two weeks, the devs get handed a spec and it's a nice discrete chunk of work that they can just do. From a documentation point of view, this has become a mess. The problem with writing specs that are focused on delivering just-in-time requirements to developers is we haven't placed much emphasis on the big picture. Specs come from all different angles - it could be describing a standard function, it could describing parts of a workflow, it could be describing a particular screen... And now, we have business rules about our application scattered across 120 documents. Looking for any document for a particular business rule or function in particular is quite hard because you don't know which document has this information, and making a change request is equally hard because once again, we are unsure about which spec to make the change. So we have maybe a couple of weeks of lull before it's back to specing out functionality for the next phase but in this time, I'd like to re-visit our processes. I think the way we have worked so far in terms of delivering fortnightly specs works well. But we also need a way to manage our documentation so that our business rules for a given function / workflow are easy to locate / change. I have two ideas. One is we compile all of our specs into a series of master specs broken by a few broad functional areas. The specs describe the sprint, the master spec describe the system. The only problem I can see is 1) Our existing 120 specs are not all neatly defined into broad functional areas. Some will require breaking up, merging etc. which will take a lot of time. 2) We'll be writing specs and updating master specs in each new sprint. Seems like double the work, and then do the devs look at the spec or the master spec? My other suggestion is to concede that our documentation is too big of a mess, and manage that mess going forward. So we go through each spec, assign like keywords to it, and then when we want to search for a function, we search for that keyword. Problems I can see 1) Still the problem of business rules scattered everywhere, keywords just make it easier to find it. anyway, if anyone has any decent ideas or any experience to share about how best to manage documentation, would really appreciate it.

• Python text file processing speed issues

  - by Anonymouslemming

  Hi all, I'm having a problem with processing a largeish file in Python. All I'm doing is f = gzip.open(pathToLog, 'r') for line in f: counter = counter + 1 if (counter % 1000000 == 0): print counter f.close This takes around 10m25s just to open the file, read the lines and increment this counter. In perl, dealing with the same file and doing quite a bit more (some regular expression stuff), the whole process takes around 1m17s. Perl Code: open(LOG, "/bin/zcat $logfile |") or die "Cannot read $logfile: $!\n"; while (<LOG>) { if (m/.*\[svc-\w+\].*login result: Successful\.$/) { $_ =~ s/some regex here/$1,$2,$3,$4/; push @an_array, $_ } } close LOG; Can anyone advise what I can do to make the Python solution run at a similar speed to the Perl solution? I've tried just uncompressing the file and dealing with it using open instead of gzip.open, but that made a very small difference to the overall time.

• Test plans and how best to write them

  - by Karim

  We're trying to figure out the best way to write tests in our test plan. Specifically, when writing a test that is meant to be used by anyone including QA staff, should the steps in the test be very specific or more broad giving the tester more leeway in how the task can be accomplished. As a very simple example, if you're testing opening a document in word processing document, should the test read: Using the mouse, open the file menu Choose "Open File..." in the file menu In the open file dialog that appears, navigate to x and double-click the document called y OR Bring up the file open dialog Open the file y Now I realize one answer is probably going to be "it depends on what you're trying to test" but I'm trying to answer a broader question here: If the test steps are too specific do we risk a) making the testing process to laborious and tedious and more importantly b) do we risk missing something because we wrote down too specific a path to achieve a goal. Alternatively, if we make it broad do we depend too much on the whims of the tester at the time and lose crucial testing of paths that are more common to customers/clients?

• How come ASUS sells Ubuntu installed 1225Cs, when we dont have drivers for gma3600?

  - by sumit_gt

  I recently purchased a ASUS 1225C cedar trail netbook. It didn't come preinstalled with Ubuntu like it comes in some markets. I installed Ubuntu 12.04 LTS on it. While Ubuntu works just fine, I am bothered by the lack of proper graphics support because of intel gma 3600. I am aware that this is not a problem of Ubuntu. My question is this: How does ASUS manage to sell these netbooks in other markets with Ubuntu preinstalled? How does ASUS manage to get everything to work? And if they can, why aren't I able to do the same? link: For more on Asus 1225C As you can see, they show Ubuntu working perfectly in the screenshots. Is this false advertising?

• Substitute Items on Internal Sales Orders

  - by ChristineS-Oracle

  Oracle Order Management now enables you to substitute items on internal sales order lines to manage item availability.  Oracle Order Management enables you to substitute items on internal sales order lines to manage item availability. Source organizations can decide to ship a substitute item in case the original item is not available to be shipped. The application supports manual (using Related Items window) and automatic (using ATP functionality) substitutions.To substitute an item on ISO, you must ensure that the value of the Item Substitution on Internal Order system parameter is set to a value other than None. In addition, you must ensure to define substitute item relationships and automatic item substitution setup in the system. The application provides the option to not send the notifications when any change happens on the ISO related to quantity, schedule arrival date, or item. You can control these notifications using the OM: Send Notifications of Internal Order Change profile option. For additional information refer to the Oracle Order Management Release Notes for Release 12.2.4 (Doc ID 1906521.1).

• Touch Event Not Work With PinchZoom

  - by Siddharth

  I was implemented pinch zoom functionality for my tower of defense game. I manage different entity to display all the towers. From that entity game player select the tower and drag to the actual position where he want to plot the tower. I set the entity in HUD also, so user scroll and zoom the region, the tower become visible all the time. Basically I have created the different entity to show and hide towers only so I can manage it easily. My problem is when I have not perform the scroll and zoom the tower touch and the dragging easily done but when I zoom and scroll the scene at that time the tower touch event does not call so the player can not able to drag and drop it to actual position. So anybody please help me to come out of it.

• ASUS U24a can't boot without live disk

  - by user98965

  I recently picked up a new ASUS U24a while travelling in asia. I've managed to go through hell with the UEFI setup, and finally now have a working GRUB. However, I can't manage to get past the "Loading initial ramdisk". If I boot the live CD-USB (only in BIOS legacy mode), I get a wonderful, working Ubuntu. I finally managed to get UEFI installed on the hard-drive (no option for legacy BIOS boot, or I'd be there in a flash!), and can boot in UEFI mode into GRUB2. But... I can't manage to get past the "loading initial ramdisk". It appears that the disk drivers are failing (there is no disk activity after this point). Ideas? pastebin from the boot-repair is at: http://paste.ubuntu.com/1290011/ best, -tony

• MySqlConnection really not close

  - by stighy

  Hi guys, i've a huge problem. Take a look to this sample code private sub FUNCTION1() dim conn as new mysqlconnection(myconnstring) conn.open ---- do something FUNCTION2() ---- conn.close end sub private sub FUNCTION2() dim conn as new mysqlconnection(myconnstring) .... conn.open -- do something conn.close end sub Despite i close regulary all my connection, they remains "open" on the mysql server. I know this because i'm using MySQL Administration tool to check how many connection i open "line by line" of my source code. In fact i get a lot of time "user has exceeded the 'max_user_connections' resource (current value: 5)" My hoster permit ONLY 5 connection, but i think that if i write GOOD source code, this cannot be a problem. So my question is: why that "damn" connections remain open ?? Thank you in advance!

• how to use version control

  - by ptamzz

  I'm developing a web site in php in localhost and as modules of it gets completed, I upload it on the cloud so that my friends can alpha test it. As I keep developing, I've lots of files and I lose track of which file I've edited or changed etc. I've heard of something as 'version control' to manage all those but am not sure how it works. So, my question is: Is there an easy way/service/application available to me to track all the edits/changes/new files and manage the files as I develop the website. As Soon as I'm done with a module, I want to upload it on the cloud (I'm using Amazon Cloud Service). If something happens to the new files, I might want to get back to the old file. And maybe, in a click or two, I get to see the files which I've edited or changed since the last one I've uploaded?

• F# WPF Form &ndash; the basics

  - by MarkPearl

  I was listening to Dot Net Rocks show #560 about F# and during the podcast Richard Campbell brought up a good point with regards to F# and a GUI. In essence what I understood his point to be was that until one could write an end to end application in F#, it would be a hard sell to developers to take it on. In part I agree with him, while I am beginning to really enjoy learning F#, I can’t but help feel that I would be a lot further into the language if I could do my Windows Forms like I do in C# or VB.NET for the simple reason that in “playing” applications I spend the majority of the time in the UI layer… So I have been keeping my eye out for some examples of creating a WPF form in a F# project and came across Tim’s F# Twitter Stream Sample, which had exactly this…. of course he actually had a bit more than a basic form… but it was enough for me to scrap the insides and glean what I needed. So today I am going to make just the very basic WPF form with all the goodness of a XAML window. Getting Started First thing we need to do is create a new solution with a blank F# application project – I have made mine called FSharpWPF. Once you have the project created you will need to change the project type from a Console Application to a Windows Application. You do this by right clicking on the project file and going to its properties… Once that is done you will need to add the appropriate references. You do this by right clicking on the References in the Solution Explorer and clicking “Add Reference'”. You should add the appropriate .Net references below for WPF & XAMl to work. Once these references are added you then need to add your XAML file to the project. You can do this by adding a new item to the project of type xml and simply changing the file extension from xml to xaml. Once the xaml file has been added to the project you will need to add valid window XAML. Example of a very basic xaml file is shown below… <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="F# WPF WPF Form" Height="350" Width="525"> <Grid> </Grid> </Window> Once your xaml file is done… you need to set the build action of the xaml file from “None” to “Resource” as depicted in the picture below. If you do not set this you will get an IOException error when running the completed project with a message along the lines of “Cannot locate resource ‘window.xaml’ You then need to tie everything up by putting the correct F# code in the Program.fs to load the xaml window. In the Program.fs put the following code… module Program open System open System.Collections.ObjectModel open System.IO open System.Windows open System.Windows.Controls open System.Windows.Markup [<STAThread>] [<EntryPoint>] let main(_) = let w = Application.LoadComponent(new System.Uri("/FSharpWPF;component/Window.xaml", System.UriKind.Relative)) :?> Window (new Application()).Run(w) Once all this is done you should be able to build and run your project. What you have done is created a WPF based window inside a FSharp project. It should look something like below…   Nothing to exciting, but sufficient to illustrate the very basic WPF form in F#. Hopefully in future posts I will build on this to expose button events etc.

• Issues printing through ssh tunnel and port forwarding

  - by simogasp

  I'm having some problems trying to print through a ssh tunnel. I'd like to print from my laptop to a network printer (Toshiba es453, for what matters) which is in a local network. I can reach the local network using a gateway. So far I did the following: ssh -N -L19100:<Printer_IP>:9100 <username>@<ssh_gateway> Basically i just mapped the port 19100 of my laptop directly to the input port of the printer, passing through the gateway. So far, so good. Then, i tried to install on my laptop a new printer with the GUI config tool of ubuntu, so that the new printer is on localhost at port 19100 (as APP Socket/HP Jet Direct) , then I provided the proper driver of the printer. In theory, once the tunnel is open I should be able to print from any program just selecting this printer. Of course, it does not work. :-) The document hangs in the queue with status Processing while in the shell where I set up the tunnel I get these errors on failing opening channels debug1: Local forwarding listening on ::1 port 19100. debug1: channel 0: new [port listener] debug1: Local forwarding listening on 127.0.0.1 port 19100. debug1: channel 1: new [port listener] debug1: Requesting [email protected] debug1: Entering interactive session. debug1: Connection to port 19100 forwarding to 195.220.21.227 port 9100 requested. debug1: channel 2: new [direct-tcpip] debug1: Connection to port 19100 forwarding to 195.220.21.227 port 9100 requested. debug1: channel 3: new [direct-tcpip] channel 2: open failed: connect failed: Connection timed out debug1: channel 2: free: direct-tcpip: listening port 19100 for 195.220.21.227 port 9100, connect from ::1 port 44434, nchannels 4 debug1: Connection to port 19100 forwarding to 195.220.21.227 port 9100 requested. debug1: channel 2: new [direct-tcpip] channel 3: open failed: connect failed: Connection timed out debug1: channel 3: free: direct-tcpip: listening port 19100 for 195.220.21.227 port 9100, connect from ::1 port 44443, nchannels 4 channel 2: open failed: connect failed: Connection timed out debug1: channel 2: free: direct-tcpip: listening port 19100 for 195.220.21.227 port 9100, connect from ::1 port 44493, nchannels 3 debug1: Connection to port 19100 forwarding to 195.220.21.227 port 9100 requested. debug1: channel 2: new [direct-tcpip] As a further debugging test I tried the following. From a machine inside the local network I did a telnet <IP_printer> 9100, got access, wrote some random thing, closed the connection and correctly I got a print of what I had written. So the port and the ip of the printer should be correct. I tried the same from my laptop with the tunnel opened, the telnet succeeded but, again, the printer didn't print anything, getting the usual channel x: open failed: errors. I'm not a great expert on the matter, I just thought that in theory it was possible to do something like that, but maybe there is something that I didn't consider or I did wrong. Any clue? Thanks! Simone [update] As further debugging test, I tried to replicate the procedure from a machine in the local network. From that machine, I did ssh -N -L19100:<IP_printer>:9100 <username>@<ssh_gateway> (note that now the machine, the gateway and the printer are in the same local network) then I tried again the telnet test with telnet localhost 19100, I got access and everything, but I didn't get the print but the usual error channel 2: open failed: connect failed: Connection timed out Maybe I am missing some other connection to be forwarded or maybe this is not allowed by the administrators. Of course, if I connect via ssh tunneling to the local machine from my laptop through the gateway, I can successfully print using the lpr command (from the local machine). But this is what I would like to avoid (yes, I'm lazy...:-), I would like to have a more 'elegant' and transparent way to do that.

• How to Create SharePoint List and Insert List Item programmatically from a Windows Forms Application.

  - by Michael M. Bangoy

  In this post I’m going to demonstrate how to create SharePoint List and also Insert Items on the List from a Windows Forms Application. 1. Open Visual Studio and create a new project. On the project template select Windows Form Application under C#. 2. In order to communicate with Sharepoint from a Windows Forms Application we need to add the 2 Sharepoint Client DLL located in c:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI.  3. Select the Microsoft.Sharepoint.Client.dll and Microsoft.Sharepoint.Client.Runtime.dll. (Your solution should look like the one below) 4. Open the Form1 in design view and from the Toolbox menu add a button on the form surface. Your form should look like the one below. 5. Double click the button to open the code view. Add Using statement to reference the Sharepoint Client Library then create method for the Create List. Your code should like the codes below. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Security; using System.Windows.Forms; using SP = Microsoft.SharePoint.Client; namespace ClientObjectModel {     public partial class Form1 : Form     {         // url of the Sharepoint site         const string _context = "urlofthesharepointsite";         public Form1()         {             InitializeComponent();         }         private void Form1_Load(object sender, EventArgs e)         {                    }         private void cmdcreate_Click(object sender, EventArgs e)         {             try             {                 // declare the ClientContext Object                 SP.ClientContext _clientcontext = new SP.ClientContext(_context);                 SP.Web _site = _clientcontext.Web;                 // declare a ListCreationInfo                 SP.ListCreationInformation _listcreationinfo = new SP.ListCreationInformation();                 // set the Title and the Template of the List to be created                 _listcreationinfo.Title = "NewListFromCOM";                 _listcreationinfo.TemplateType = (int)SP.ListTemplateType.GenericList;                 // Call the add method to the ListCreatedInfo                 SP.List _list = _site.Lists.Add(_listcreationinfo);                 // Add Description field to the List                 SP.Field _Description = _list.Fields.AddFieldAsXml(@"                                     <Field Type='Text'                                         DisplayName='Description'>                                     </Field>", true, SP.AddFieldOptions.AddToDefaultContentType);                 // declare the List item Creation object for creating List Item                 SP.ListItemCreationInformation _itemcreationinfo = new SP.ListItemCreationInformation();                 // call the additem method of the list to insert a new List Item                 SP.ListItem _item = _list.AddItem(_itemcreationinfo);                 _item["Title"] = "New Item from Client Object Model";                 _item["Description"] = "This item was added by a Windows Forms Application";                 // call the update method                 _item.Update();                 // execute the query of the clientcontext                 _clientcontext.ExecuteQuery();                 // dispose the clientcontext                 _clientcontext.Dispose();                 MessageBox.Show("List Creation Successfull");             }             catch(Exception ex)             {                 MessageBox.Show("Error creating list" + ex.ToString());             }          }     } } 6. Hit F5 to run the application. A message will be displayed on the screen if the operation is successful and also if it fails. 7. To make that the operation of our Windows Form Application has really created the List and Inserted an item on it. Let’s open our SharePoint site. Once the SharePoint is open click on the Site Actions then View All Site Content. 7. Click the List to open it and check if an Item is inserted. That’s it. Hope this helps.

• Help Email Account Management among multiple users

  - by CogitoErgoSum

  So I preface this with saying this may belong in IT Security, not too sure feel free to move. Currently we have an email account [email protected] - hosted via google apps (as is all our email). We had an incident where we had to terminate an employee. This employee however had the password for this account as we have 20-30 people utilizing it at any given point to manage customer emails etc. Thinking on this I feel there must be a better way to manage access. With Google you can associate upto 10 email accounts to another the problem is we have more like 20-30 people going. We were evaluating tools such as SalesForce and Assistly where people have their own login credentials and then the system contains the appropriate smtp information for the [email protected] email address to send emails from it rather than a users personal account. Aside from those options does anyone have any other thoughts? One suggestion floated was moving everyone to desktop clients and saving the PW info there so they could only login from their physical workstation but we may have situations where we'd like employees to work remotely. Does anyone have experience with this sort of system where ~20-30 people are responding from one email box and how to manage security and access?

• Are Windows Domain Service Accounts Really Necessary?

  - by Zach Bonham

  One of the biggest problems we have in automating application deployments is the idea that running IIS AppPools and Windows Services under domain service accounts is a 'best practice'. Unfortunately, this best practice sometimes causes deployment headaches in that either we need to provision a new domain level service account quickly, or once we have the account, we now need to manage the account credentials. I had a great conversation about not making domain level service accounts a requirement and effectively taking one of two approaches: Secure at the node level using machine account(domain\machine$) and add the node to appropriate ActiveDirectory/Sql groups/roles Create local app specific accounts on each machine (machine\myapp) and add that account to appropriate ActiveDirectory/Sql groups/roles (the password here can change per deployment, it doesn't need to be stored) In both cases, it seems that its easier to manage either adding an account to appropriate group/role, or even stand up new, local account, than it is to have to provision a new domain level account and manage those credentials. This would hopefully ease the management burden on ActiveDirectory, Sql Server and Operations teams as there would be no more password management. We've not actually been able to implement this in practice yet. I am coming from a development background, so I'm curious as to how many ways this approach could go wrong? Can we really get rid of domain level service accounts with this direction? I'd appreciate any thoughts from anyone who has taken this path! Thanks! Zach

• Win7 Domain User Profile- Desktop Icon management best practices request

  - by Doltknuckle

  Here's the situation: We have a large (5,000+ user) organization that is currently using folder redirection to manage the windows desktop icons. This folder is redirected to a network share where we can centrally manage the different sites and such. When a user tries to use a computer when the network is not available, they are unable to use any shortcuts in the Public folder. We only redirect the C:\Users\%username%\Desktop folder. Does anyone have any suggestions of how to go about managing desktop icons? We still want a central location to manage these items, but find a way to keep the system working when the network is unavailable. As a point of clarification, the network rarely goes down. We do have instances where a few computers do not have a network connection. Usually, something is simply unplugged. Since we have multiple sites, the line from a branch to the central office has gone down a few times. This is more of an attempt to maintain a positive end user experience when disconnected from the network.

• Sudden issues reading uncompressed video using opencv

  - by JohnSavage

  I have been using a particular pipeline to process video using opencv to encode uncompressed video (fourcc = 0), and opencv python bindings to then open and work on these files. This has been working fine for me on OpenCV 2.3.1a on Ubuntu 11.10 until just a few days ago. For some reason it currently is only allowing me to read the first frame of a given file the first time I open that file. Further frames are not read, and once I touch the file once with my program, it then cannot even read the first frame. More detail: I created the uncompressed video files as follows: out_video.open(out_vid_name, 0, // FOURCC = 0 means record raw fps, Size(640, 480)) Again, these videos worked fine for me until about a week ago. Now, when I try to open one of these I get the following message (from what I think is ffmpeg): Processing video.avi Using network protocols without global network initialization. Please use avformat_network_init(), this will become mandatory later. [avi @ 0x29251e0] parser not found for codec rawvideo, packets or times may be invalid. It reads and displays the first frame fine, but then fails to read the next frame. Then, when I try to run my code on the same video, the capture still opens with the same message as above. However, it cannot even read the very first frame. Here is the code to open the capture: self.capture = cv2.VideoCapture(filename) if not self.capture.isOpened() print "Error: could not open capture" sys.exit() Again, this part is passed without any issue, but then the break happens at: success, rgb = self.capture.read() if not success: print "error: could not read frame" return False This part breaks at the second frame on the first run of the video file, and then on the first frame on subsequent runs. I really don't know where to even begin debugging this. Please help!

• My First F# program

  - by sudaly

  Hi I just finish writing my first F# program. Functionality wise the code works the way I wanted, but not sure if the code is efficient. I would much appreciate if someone could review the code for me and point out the areas where the code can be improved.
