• Can a custom DPI setting be applied to Remote Desktop sessions?

  - by sejong

  Can a custom DPI setting be applied to Remote Desktop sessions? When you try to change the DPI from a Remote Desktop session, you get a message that display settings can't be changed from a remote session. That made me think that changing DPI from a console setting would work. It did, sort of. If I connected via Remote Desktop to an existing console session with a custom DPI setting, that setting would be applied to the Remote Desktop session. However, if I logged off that session, the custom DPI would not be applied to subsequent Remote Desktop sessions even though it was maintained for subsequent console sessions. It looks like the registry value HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics\AppliedDPI (and perhaps other values) is overwritten at logon, but I haven't been able figure out how to prevent it.

• Can I fine-tune my screen brightness? (Ubuntu Studio, Thinkpad T420s)

  - by Dan S

  I am in a similar situation as question Can I fine-tune my screen brightness? . For me, Thinkpad T420s and Ubuntu Studio 11.10. The brightness keys work fine but the increments are too large. I have the /sys/class/backlight/acpi_video0 and I can see the value of actual_brightness changing as I use the brightness keys - it changes between values 0,3,6,9,12,15. None of the listed answers for fine control works here, as follows: As the root user I can echo integers to brightness in the above folder. As an ordinary user I cannot. I do not have /usr/sbin/gnome-power-backlight-helper (because I'm using xfce perhaps?), and not sure what package it's from or if installing such a package would make sense since it's not what's currently managing the backlight. How can it be done, please?

• What kind of permission is this? (Groups+Roles)

  - by Jorge

  I'm starting to need an access control for roles in my app. I don't know much of this, but I understand how vBulletin works: I create groups, then give permissions to groups. I think that what I need is the Role Bases Access Control (RBAC) , but i'm not sure, because I need groups to give permissions instead of single users (Maybe it's not that complicated to achieve). Example of what I'm thinking: Given a post: Editor's Group has permission to view it before it's published. Editor's Group has permission to edit its content. Public Group (Default) has not permission to view it before it's published. Admin Group has permission to delete the post. So basically I wan't orientation about if RBAC is what I need. And also, how would it be good to store group membership in a user, for example, would be good to have: ID NAME PASSWORD GROUPS (1, MyName, MyPassword, 1/2/3/4/5) and explode it via PHP or one registry for every Group membership in a table named permissions, example: USERID, USERGROUP values (1, 1), (1, 2) Maybe should be the second way because of the formal norms but I didn't study yet Databases 1 at college.

• Pull Request Conversations, Inline Diff Enhancements

  [Do you tweet? Follow us on Twitter @matthawley and @adacole_msft] We deployed a new version of the CodePlex website today. Pull Request Conversations Previously, the only way for project members and users who submitted pull requests to converse was via e-mail. This complicated the review process and made conversations isolated and difficult to track. For this release, we’ve added functionality that enables you to have those same conversations within the pull request page. When you view a pull request, you’ll now see “Comments” and “Changes” tabs, with current comments displayed. Inline Diff Enhancements We tweaked the inline diff experience to make it easier to traverse diff blocks. When you open up the inline diff experience, you’ll now see up and down arrows. To move between the diff blocks, you can use those arrows or utilize the available keyboard shortcuts. Lastly, we have also brought the inline diff experience to the source control changes page for project and fork changesets. You can see both enhancements live by viewing the associated pull request or changeset changes on WikiPlex. The CodePlex team values your feedback. We are frequently monitoring Twitter, our Discussions, and Issue Tracker. If you have not visited the Issue Tracker recently, please take a few minutes to suggest or vote on a feature you would like to see implemented.

• How to setup my texture cordinates correctly in GLSL 150 and OpenGL 3.3?

  - by RubyKing

  I'm trying to do texture mapping in GLSL 150 and OpenGL 3.3 Here are my shaders I've tried my best to get this correct as possible hopefully this is :) I'm guessing you want to know what the problem is well my texture shows but not in its fullest form just one section of it not the full texture on the quad. All I can think of is its the texture cordinates in the main.cpp which is at the bottom of this post. FRAGMENT SHADER #version 150 in vec2 Texcoord_VSPS; out vec4 color; // Values that stay constant for the whole mesh. uniform sampler2D myTextureSampler; //Main Entry Point void main() { // Output color = color of the texture at the specified UV color = texture2D( myTextureSampler, Texcoord_VSPS ); } VERTEX SHADER #version 150 //Position Container in vec3 position; //Container for TexCoords attribute vec2 Texcoord0; out vec2 Texcoord_VSPS; //out vec2 ex_texcoord; //TO USE A DIFFERENT COORDINATE SYSTEM JUST MULTIPLY THE MATRIX YOU WANT //Main Entry Point void main() { //Translations and w Cordinates stuff gl_Position = vec4(position.xyz, 1.0); Texcoord_VSPS = Texcoord0; } LINK TO MAIN.CPP http://pastebin.com/t7Vg9L0k

• How can I insert the quoted price of gold from kitco.com into my excel spreadsheet?

  - by Frank Computer

  kitco.com provides a realtime price quote for gold and other metals. I have a spreadsheet which makes calculations based on the price of gold and would like for this realtime value to automatically be updated on my excel sheet. I tried 'get external data' from a website but that didn't work. any ideas? EDIT ADDED: Kitco has a gadget called KCAST which displays realtime quotes on the Windows taskbar. I tried capturing those values from the taskbar but that didn't work either. Maybe if Kitco provided an API or feed, it could be done?

• Are specific types still necessary?

  - by MKO

  One thing that occurred to me the other day, are specific types still necessary or a legacy that is holding us back. What I mean is: do we really need short, int, long, bigint etc etc. I understand the reasoning, variables/objects are kept in memory, memory needs to be allocated and therefore we need to know how big a variable can be. But really, shouldn't a modern programming language be able to handle "adaptive types", ie, if something is only ever allocated in the shortint range it uses fewer bytes, and if something is suddenly allocated a very big number the memory is allocated accordinly for that particular instance. Float, real and double's are a bit trickier since the type depends on what precision you need. Strings should however be able to take upp less memory in many instances (in .Net) where mostly ascii is used buth strings always take up double the memory because of unicode encoding. One argument for specific types might be that it's part of the specification, ie for example a variable should not be able to be bigger than a certain value so we set it to shortint. But why not have type constraints instead? It would be much more flexible and powerful to be able to set permissible ranges and values on variables (and properties). I realize the immense problem in revamping the type architecture since it's so tightly integrated with underlying hardware and things like serialization might become tricky indeed. But from a programming perspective it should be great no?

• opengl 3d point cloud render from x,y,z 2d array with texture

  - by user1733628

  Need some direction on 3d point cloud display using openGl in c++ (vs2008). I am brand new to openGl and trying to do a 3d point cloud display with a texture. I have 3 2D arrays (each same size 1024x512) representing x,y,z of each point. I think I am on the right track with glBegin(GL_POLYGON); for(int i=0; i<1024; i++) { for(int j=0; j<512; j++) { glVertex3f(x[i][j], y[i][j], z[i][j]); } } glEnd(); Now this loads all the vertices in the buffer (i think) but from here I am not sure how to proceed. Or I am completely wrong here. Then I have another 2D array (same size) that contains color data (values from 0-255) that I want to use as texture on the 3D point cloud and display. I understand that this maybe a very basic opengl implementation for some but for me this is a huge learning curve. So any pointers, nudge or kick in the right direction will be appreciated.

• Best Practice: What can be the hashCode() method implementation if custom field used in equals() method are null?

  - by goodspeed

  What is the best practice to return a value for hashCode() method if custom field used in equals are null ? I have a situation, where equals() override is implemented using custom fields. Usually it it is better to override hashCode() also using that custom fields used in equals(). But if all the custom fields used in equals() are null, then what would be the best implementation for hashCode()? Example: class Person { private String firstName; private String lastName; public String getFirstName() { return firstName; } public String getLastName() { return lastName; } @Override public boolean equals(Object object) { boolean result = false; if (object == null || object.getClass() != getClass()) { result = false; } else { Person person = (Person) object; if (this.firstName == person.getFirstName() && this.lastName == tiger.getLastName()) { result = true; } } return result; } @Override public int hashCode() { int hash = 3; if(this.firstName == null || this.lastName == null) { // <b>What is the best practice here, </b> // <b>is return super.hashCode() better ?</b> } hash = 7 * hash + this.firstName.hashCode(); hash = 7 * hash + this.lastName.hashCode(); return hash; } } is it required to check for null in hashCode() ? If yes, what should be returned if custom values are null ?

• Nullable types and ?? operator C# [en-US]

  - by ruimachado

  Nullable types vs Non-nullable types   While developing our C# projects its frequent the null comparison operation to avoid null exceptions. This simple operation is mainly coded using the "var x = null" code example inside an if clause. However not all types of variables are nullable, which means that setting a variable to null is not allowed in every cases, it depends on what kind of type are you defining. But what if there was an extension to your non-nullable type that would convert your variable types to nullable? This extension really exists. As I said before in C# you have nullable types which represent all the values of an underlying type, and an additional null value and can be declared easily using "T?", where T is the type of the variable and for example the normal int type cannot be null, so its a non-nullable type, however if you define a "int?" your variable can be null, what you do is convert a non-nullable type to a nullable type. Example: int x=null;     Not allowed     int? x=null;   Allowed     While using nullable types you can check if a variable is null the same way you do it with nullable types:     But what about setting a default value when a certain variable is null?   In this cases the c# .net framework let you set a default value when you try to assign a nullable type to a non-nullable type, using the ?? operator. If you don't use this operator you can still catch the InvalidOperationException which is throw in this cases. For example  without the ?? operator :     Using the ?? operator your code becomes cleaner and more easy to read and you get a bonus, you can set a default value for multiple variables using the ?? in a chain set.     That’s it,   Thanks, Rui Machado rpmachado.wordpress.com

• Simple C: How do I scan this information in properly?

  - by Doc

  OK this is a simple question but for some reason I just can't get it right. I have to scan from a file hundreds of lines of code and store it in a array (which I can normally do a ok job with) however At one point the code will specify a number that then corresponds to the next batch of chars ints and floats going into various arrays. As I know I am not describing this correctly here is a example. one line of the file I am reading will contain something close to this. 0221 T 2 S P 850 150 0.90 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Name_of_place 0104 L 1 F 400 1.00 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Ballroom the problem I am having is This part here 0221 T 2 S P 850 150 0.90 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Name_of_place 0104 L 1 F 400 1.00 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Ballroom The rest after this is Generally the exact same however at this point the number at the front descides all the values that are going in. I am almost completely lost on how to write a way that can scan this and store the data into arrays correctly

• How to properly set CPU Units for OpenVz VEs

  - by gucki

  According to all the sources I read (openvz wiki, various mailinglists, forums, ..) the values of the cpuunits settings are relative to each other. So when all are equal and the system is busy, all receive the same cpu share. But something still puzzles me with that: why is there a tool "vzcpucheck" which shows "the power of the node/ host": Current CPU utilization: 18000 Power of the node: 880001 Why is there (do I need) an absolute number when all settings are only relative? Shouldn't those two settings result in exactly the same? ve1: 1 ve2: 1 ve3: 1 = 3 ve1: 293334 ve1: 293334 ve1: 293334 = 880001 (power of the node) What's the difference?

• JavaScript and the User Experience

  5 sites I commonly vist at home: Google.com Gmail.com Linkedin.com Capella.edu Codeplex.com All of the top 5 sites I visit at home use JavaScript and is applied in various ways for various reasons. Gmail and Google make use of Ajax to retrieve information without the user having to call another page. In addition, all 5 of the websites use JavaScript to enhance a user's experience. Examples of this can be found in content rotation on Capella's main site and the displaying and hiding of specific content sections from within our course room. Codeplex uses Ajax and JavaScript to show dynamic content on its homepage and allow users to page through the data. I think there use of JavaScript is well placed and enhances the viewing experience of the user because it reduces the amount of interaction a user has to perform for them to obtain information they are looking to see. I have used JavaScript in various ways. One of the most memorable ways was to enable an HTML table to be able to have its rows paged and sorted based on the values in each table row.

• Do you write unit tests for all the time in TDD?

  - by mcaaltuntas

  I have been designing and developing code with TDD style for a long time. What disturbs me about TDD is writing tests for code that does not contain any business logic or interesting behaviour. I know TDD is a design activity more than testing but sometimes I feel it's useless to write tests in these scenarios. For example I have a simple scenario like "When user clicks check button, it should check file's validity". For this scenario I usually start writing tests for presenter/controller class like the one below. @Test public void when_user_clicks_check_it_should_check_selected_file_validity(){ MediaService service =mock(MediaService); View view =mock(View); when(view.getSelectedFile).thenReturns("c:\\Dir\\file.avi"); MediaController controller =new MediaController(service,view); controller.check(); verify(service).check("c:\\Dir\\file.avi"); } As you can see there is no design decision or interesting code to verify behaviour. I am testing values from view passed to MediaService. I usually write but don't like these kind of tests. What do yo do about these situations ? Do you write tests for all the time ? UPDATE : I have changed the test name and code after complaints. Some users said that you should write tests for the trivial cases like this so in the future someone might add interesting behaviour. But what about “Code for today, design for tomorrow.” ? If someone, including myself, adds more interesting code in the future the test can be created for it then. Why should I do it now for the trivial cases ?

• Excel - Disable AutoFormatting on Import

  - by Philip Wales

  How can I stop Microsoft Excel from auto formatting data when imported from a text file? Specifically, I want it to treat all of the values as text. I am auditing insurance data in excel before it is uploaded to the new database. The files come to me as tab delimited text files. When loaded, Excel auto-formats the data causing leading 0's on Zip Codes, Routing Numbers and other codes, to be chopped off. I don't have the patience to reformat all of the columns as text and guess how many zeros need to be replaced. Nor do I want to click through the import wizard an specify that each column is text. Ideally I just want to turn off Excel's Auto-Formatting completely, and just edit every cell as it were plain text. I don't do any formula's or charts, just grid plain text editing.

• Dividing with Gnu's bc

  I'm just starting with Gnu's bc and I'm stuck at the very beginning (very discouraging...). I want to divide two numbers and get a float as result: $bc bc 1.06.94 Copyright 1991-1994, 1997, 1998, 2000, 2004, 2006 Free Software Foundation, Inc.

• How do I populate multiple records of data into a PDF form like a mail-merge?

  - by user38801

  I have Acrobat Pro, and I have a PDF with a form on it. Assuming the fields in the form correspond to a data source (like rows in an RDBMS table or xml file), I want to then print multiple copies of the PDF file, with each copy having the values of a different row in the data source. It is preferable to directly interface with an actual database, rather than having to save an XML file every time I do this. If this involves programming that's cool too, I only posted here because the question didn't seem appropriate for StackOverflow. Thanks!

• gmetric data submitted doesn't follow dmax value

  - by 580farm

  I have a custom script that is querying a metric port for an application that I'm running and submitting parsed values to ganglia via gmetric. The script runs every minute, so I submit the data to ganglia using the following gmetric options: /usr/sbin/gmetric -g ec2 -s positive -t uint32 -d 600 -n "$NAME" -v $VALUE -x 60 But for some reason there are still gaps in the graphing data: Is there something in my formatting that is preventing the dmax/ttl of the last metric received from being honored? Is there anyone who does custom metric collection that has run into this problem before that can shed some insight or provide some tips as to how to best correct this?

• Should static parameters in an API be part of each method?

  - by jschoen

  I am currently creating a library that is a wrapper for an online API. The obvious end goal is to make it as easy for others to use as possible. As such I am trying to determine the best approach when it comes to common parameters for the API. In my current situation there are 3 (consumer key, consumer secret, and and authorization token). They are essentially needed in every API call. My question is should I make these 3 parameters required for each method or is there a better way. I see my current options as being: Place the parameters in each method call public ApiObject callMethod(String consumerKey, String consumerSecret, String token, ...) This one seems reasonable, but seems awfully repetitive to me. Create a singleton class that the user must initialize before calling any api methods. This seems wrong, and would essentially limit them to accessing one account at a time via the API (which may be reasonable, I dunno). Make them place them in a properties file in their project. That way I can load the properties that way and store them. This seems similar to the singleton to me, but they would not have to explicitly call something to initialize these values. Is there another option I am not seeing, or a more common practice in this situation that I should be following?

• Apache mod_header rule to change all cookies to secure

  - by Supowski

  I would like to change all cookies to be secure and http-only. I works fine for one cookie, but doesn't work when multiple cookies are set in response. Apache mod_header rule should change cookies from: Set-Cookie cookie1=value; Path=/somePath Set-Cookie cookie2=value; Path=/somePath to Set-Cookie cookie1=value; Path=/somePath; Secure; Http-Only Set-Cookie cookie2=value; Path=/somePath; Secure; Http-Only I use mod_headers for it with following rule: Header edit Set-Cookie ^(.*)$ $1;Secure;HttpOnly It works fine when only one cookie is set, but if there is more than one, it just removes all the following and they are not set at all. Any help how to write mod_headers rule for multiple values? or the problem is in something else?

• Mouse pointer size inconsistent

  - by charon00

  Since installing Ubuntu 12.04, I've been having a problem with the mouse pointer size. On the desktop, it is quite a bit larger than it should be (24), though the different cursors (editing text, hyperlink hand, etc) are correct. The size changes to the correct size when the pointer is over some application windows (GVim, Netbeans, Firefox), but then changes back once it is moved out of the window. There was a similar question here, but the Xdefaults solution did not work for me, and I didn't want to try the one requiring editing the icon image. In addition, I've tried changing the cursor theme using sudo update-alternatives --config x-cursor-theme as well as using the dconf-editor, but though I can change the theme, the size issue remains. In case it's relevant, I'm running on a dual-screen setup with monitor sizes of 2560x1600 and 1920x1080, using the NVidia video driver. Is there another way to control pointer size, or a setting that might be messing it up? EDIT: These are the values/options I have for update-alternatives and in dconf-editor. I'm now wondering if Netbeans and Firefox are making the mouse pointer smaller than it should be, but I'm not sure how big 24 should be... update-alternatives: Selection Path Priority Status ------------------------------------------------------------ 0 /usr/share/icons/DMZ-White/cursor.theme 90 auto mode 1 /etc/X11/cursors/core.theme 30 manual mode 2 /etc/X11/cursors/handhelds.theme 20 manual mode 3 /etc/X11/cursors/redglass.theme 20 manual mode 4 /etc/X11/cursors/whiteglass.theme 20 manual mode * 5 /usr/share/icons/DMZ-Black/cursor.theme 30 manual mode 6 /usr/share/icons/DMZ-White/cursor.theme 90 manual mode dconf-editor: I can't post the image since I'm a new user but the cursor-size is set to 24 and the cursor-theme is DMZ-Black.

• How to increase the disk cache of Windows 7

  - by Mark Christiaens

  Under Windows 7 (64 bit), I'm reading through 9000 moderately sized files. In total, there is more than 200 MB of data. Using Java (JDK 1.6.21) I'm iterating over the files. The first 1400 or so go at full speed but then speed drops off to 4ms per file. It turns out that the main cost is incurred simply by opening the files. I'm opening the files using new FileInputStream (and of course closing them in time to avoid file leaks). After some investigating, I see that Windows' disk cache is using only 100 MB or so of RAM although I have 8 GiB available. I've tried increasing the cache size using the CacheSet tool but any values I provide are considered out of range. I've also tried enabling the LargeSystemCache registry key but (after rebooting) the CacheSet tool still indicates I'm using 100 MB of cache (and doesn't increase during the test run). Does anybody have any suggestions to "encourage" Windows 7 to cache my 9000 files?

• How to modify partitions after install?

  - by ChocoDeveloper

  I wanted to have Ubuntu with full disk encryption on one big partition, and Windows on a small one. In 12.04, only the Server Edition installer has full disk encryption, so I used that and then installed ubuntu-desktop. When it asked for the size, I reduced it from ~999GB to ~750gb. Now after the install, on both gparted and disk utility I see /dev/sda2 taking ~931GB, and nothing unallocated, so I can't create a partition for windows. I got the size right, because when I right-click inside a folder, then hit 'properties', I see Free space: ~690GB (I don't know why it's not ~750GB, but at least it's not 900). The command df -h shows the same. So what can I do? Normally I would just resize a partition with gparted to create unallocated space, then create the partition. But here I have two problems: gparted does not seem to be showing the correct values, and also it says it does not support LUKS so I'm afraid it will mess things up. Any thoughts?

• Does admin=true and root has the same privileges on AIX?

  - by Boaz Tirosh

  Does a user in /etc/security/user with the parameter admin set to true (admin = true) has the same privileges as the root user? According to IBM (full information here): admin Defines the administrative status of the user. Possible values are: true The user is an administrator. Only the root user can change the attributes of users defined as administrators. false The user is not an administrator. This is the default value. Is there another type of user, or are admin and root the same?
