  • Function like C# properties?

    - by alan2here
    I was directed here from SO as a better stack exchange site for this question. I've been thinking about the neatness and expression of C# properties over functions, although they only currently work where no parameters are used, and wondered. Is is possible, and if so why not, to have a stand alone function like C# property. For example: public class test { private byte n = 4; public test() { func = 2; byte n2 = func; func; } private byte func { get { return n; } set { n = value; } func { n++; } } } edit: Sorry for the vagueness first time round. I'm going to add some info and motivation. The 'n++' here is just a simple example, a placeholder, it's not intended to be representative of the actual code that would be used. I'm also looking at this from the point of view of looking at the property command as is, not in the context of using it for 'get_xyz' and 'set_xyz' member functions, which is certainly useful, but of instead comparing it more abstractly to functions and other programic elements. A 'get' property can be used instead of a function that takes no parameters, and syntactically they are perhaps only aesthetically, but as I see it noticeably nicer. However, properties also add the potential for an extra layer of polymorphism, one that relates to the 'func = 4;' getting, 'int n = func;' setting or 'func;' function like context in which they are used as well as the more common parameter based polymorphism. Potentially allowing for a lot of expression and contextual information reguarding how other would use your functions. As in many places uses and definitions would remain the same, it shouldn't break existing code. private byte func { get { } get bool { } set { } func { } func(bool) { } func(byte, myType) { } // etc... } So a read only function would look like this: private byte func { get { } } A normal function like this: private void func { func { } } A function with parameter polymorphism like this: private byte func { func(bool) { } func(byte, myType) { } } And a function that could return a value, or just compute, depending on the context it is used, that also has more conventional parameter polymorphism as well, like so: private byte func { get { } func(bool) { } func(byte, myType) { } }

  • Is Innovation Dead?

    - by wulfers
    My question is has innovation died?  For large businesses that do not have a vibrant, and fearless leadership (see Apple under Steve jobs), I think is has.  If you look at the organizational charts for many of the large corporate megaliths you will see a plethora of middle managers who are so risk averse that innovation (any change involves risk) is choked off since there are no innovation champions in the middle layers.  And innovation driven top down can only happen when you have a visionary in the top ranks, and that is also very rare.So where is actual innovation happening, at the bottom layer, the people who live in the trenches…   The people who live for a challenge. So how can big business leverage this innovation layer?  Remove the middle management layer.   Provide an innovation champion who has an R&D budget and is tasked with working with the bottom layer of a company, the engineers, developers  and business analysts that live on the edge (Where the corporate tires meet the road). Here are two innovation failures I will tell you about, and both have been impacted by a company so risk averse it is starting to fail in its primary business ventures: This company initiated an innovation process several years ago.  The process was driven companywide with team managers being the central points of collection of innovative ideas.  These managers were given no budget to do anything with these ideas.  There was no process or incentive for these managers to drive it about their team.  This lasted close to a year and the innovation program slowly slipped into oblivion…. A second example:  This same company failed an attempt to market a consumer product in a line where there was already a major market leader.  This product was under development for several years and needed to provide some major device differentiation form the current market leader.  This same company had a large Lead Technologist community made up of real innovators in all areas of technology.  Did this same company leverage the skills and experience of this internal community,   NO!!! So to wrap this up, if large companies really want to survive, then they need to start acting like a small company.  Support those innovators and risk takers!  Reward them by implementing their innovative ideas.  Champion (from the top down) innovation (found at the bottom) in your companies.  Remember if you stand still you are really falling behind.Do it now!  Take a risk!

  • JSR 355 Final Release, and moves JCP to version 2.9

    - by heathervc
    JSR 355, JCP EC Merge, passed the JCP EC Final Approval Ballot on 13 August 2012, with 14 Yes votes, 1 abstain (1 member did not vote) on the SE/EE EC, and 12 yes votes (2 members were not eligible to vote) on the ME EC.  JSR 355 posted a Final Release this week, moving the JCP program version to JCP 2.9.  The transition to a merged EC will happen after the 2012 EC Elections, as defined in the Appendix B of the JCP (pasted below), and the EC will operate under the new EC Standing Rules. In the previous version (2.8) of this Process Document there were two separate Executive Committees, one for Java ME and one for Java SE and Java EE combined. The single Executive Committee described in this version of the Process Document will be implemented through the following process: The 2012 annual elections will be held as defined in JCP 2.8, but candidates will be informed that if they are elected their term will be for only a single year, since all candidates must stand for re-election in 2013. Immediately after the 2012 election the two ECs will be merged. Oracle and IBM's second seats will be eliminated, resulting in a single EC with 30 members. All subsequent JSR ballots (even for in-progress JSRs) will then be voted on by the merged EC. For the 2013 annual elections three Ratified and two Elected Seats will be eliminated, thereby reducing the EC to 25 members. All 25 seats will be up for re-election in 2013. Members elected in 2013 will be ranked to determine whether their initial term will be one or two years. The 50% of Ratified and 50% of Elected members who receive the most votes will serve an initial two-year term, while all others will serve an initial one year term. All members elected in 2014 and subsequently will serve a two-year term. For clarity, note that the provisions specified in this version of the Process Document regarding a merged EC will apply to subsequent ballots on all existing JSRs, whether or not the Spec Leads of those JSRs chose to adopt this version of the Process Document in its entirety. <end of Appendix> Also of note:  the materials and minutes from the July EC meeting and the June EC Meeting are now available--following the July EC Meeting, Samsung and SK Telecom lost their EC seats. The June EC meeting also had a public portion--the audio from the public portion of the EC meeting are now posted online.  For Spec Leads there is also the recording of the EG Nominations call.

  • Block-level deduplicating filesystem

    - by James Haigh
    I'm looking for a deduplicating copy-on-write filesystem solution for general user data such as /home and backups of it. It should use online/inline/synchronous deduplication at the block-level using secure hashing (for negligible chance of collisions) such as SHA256 or TTH. Duplicate blocks need not even touch the disk. The idea is that I should be able to just copy /home/<user> to an external HDD with the same such filesystem to do a backup. Simple. No messing around with incremental backups where corruption to any of the snapshots will nearly always break all later snapshots, and no need to use a specific tool to delete or 'checkout' a snapshot. Everything should simply be done from the file browser without worry. Can you imagine how easy this would be? I'd never have to think twice about backing-up again! I don't mind a performance hit, reliability is the main concern. Although, with specific implementations of cp, mv and scp, and a file browser plugin, these operations would be very fast, especially when there is a lot of duplication as they would only need to transfer the absent blocks. Accidentally using conventional copy tools that do not integrate with the FS would merely take longer, waste some bandwidth when copying remotely and waste some CPU, as the duplicate data would be re-read, re-transferred and re-hashed (although nothing would be re-written), but would absolutely not corrupt anything. (Some filesharing software may also be able to benefit by integrating with the FS.) So what's the best way of doing this? I've looked at some options: lessfs - Looks unmaintained. Any good? [Opendedup/SDFS][3] - Java? Could I use this on Android?! What does [SDFS][4] stand for? [Btrfs][5] - Some patches floating around on mailing list archives, but no real support. [ZFS][6] - Hopefully they'll one day relicense under a true Free/Opensource GPL-compatible licence. Also, 2 years ago I had a go at an attempt in Python using Fuse at the file-level to be used over the top of a typical solid FS such as EXT4, but I found Fuse for Python underdocumented and didn't manage to implement all of the system calls. My first post here, so I can't post more than 2 links until I get over 10 rep: [3]: http://www.opendedup.org/ [4]: https://en.wikipedia.org/w/index.php?title=SDFS&action=edit&redlink=1 [5]: https://en.wikipedia.org/wiki/Btrfs#Features [6]: https://en.wikipedia.org/wiki/ZFS#Linux

  • Speaker Notes...

    - by wulfers
    At a .Net User Group meeting this week, I experienced two poorly prepared speakers floundering through presentations….  As a Lead Technologist at the company I work for, I have experience training technical staff and also giving presentations at code camps.  Here are a few guidelines for aspiring speakers you might find helpful…   1.       Do not stand in front of your audience and read your slides.  This is  offensive to your audience and not what they came for...  Your slides are there to reinforce the information you are presenting and to give the audience a little clarification on some terms you may use and as a visual aid for some complicated issues. 2.       Have someone review your presentation (slides, notes, …) who speaks the language you will be presenting in fluently.  Also record at least ten minutes of your presentation and have that same person review that.  One of the speakers this week used the word “Basically” fifty times in less than thirty minutes…  I started to flinch every time he used the term. 3.       Be Prepared  -  before the presentation begins.  Don’t make any last minute changes to your presentation or demo code the night before.  Don’t patch your laptop or demo servers the night before.  If possible create a virtual image that you only use for presentations and use that (refreshed before every presentation). 4.       Know the level of expertise of your audience.  Speaking above or below their abilities will make or break your presentation. 5.       Deliver what you promise. The presentation this week was supposed to be on BDD (Behavior Driven Develpment).  The presenter completely ran off track and 90% of the discussion was how his team mistakenly used TDD (Test Driven Development), and was unhappy with the results.  Based on his loss of focus we only heard a rushed 10 minute presentation on DBB which was a disservice to the audience. 6.       Practice your presentation with your own small team before you try this on a room full of people you don’t know.  A side benefit of doing this with your own team is that you can get candid feedback from your team and also get kudos for training your own team.  I find I can also turn my presentations into technical white papers and get a third benefit from the work I’ve put into a presentation. 7.       Sharpen your own saw.  Pick a topic that is fairly current.  Something you would like to learn about and would benefit your current career path. 8.       Have fun doing it.

  • Part 5: Choose the right tool - or - why

    - by volker.eckardt(at)oracle.com
    Consider the following client request “Please create a report for us to list expenses”. Which Oracle EBS tool would you choose? There are plenty of options available: Oracle Reports, or BI Publisher with PDF or Excel layout, or Discoverer, or BI Publisher Stand Alone, or PDF online generation, or Oracle WebADI, or Plain SQL*Plus as Concurrent Program, or Online review option … Assuming, you as development lead have to decide, you may decide by available skill set in your development team. However, is this a good decision? An important question to influence the decision is the “Why” question: why do you need this report, what process is behind, what exactly you like to achieve? We see often data created or printed, although it would be much better to get the data in Excel, and upload changes via WebADI directly. There are more points that should drive your decision: How many of such requirements you have got? Has this technique been used in the project already? Are there related reusable’s you may gain from? How difficult is it to maintain your solution? Can you merge this report with another one, to reduce test and maintenance work? In addition, also your own development standards should guide you a bit to come to a good decision. In one of my own projects, we discussed such topics in our weekly team meeting. By utilizing the team knowledge best, you may come to a better decision, and additionally, your team supports your decision. Unfortunately, I have rarely seen dedicated team trainings or planned knowledge transfer to support such processes. Often the pressure to deliver on time is too high to have discussion and decision time left. But exactly this can help keeping maintenance costs low by limiting the number of alternative solutions for similar requirements. Lastly, design decisions should be documented to allow another person taking this over easily. Decisions shall be reviewed and updated regularly, to reflect related procedures or Oracle products respective product versions. Summary: Oracle EBS offers plenty of alternatives to implement customizations. Create and maintain a decision tree to support the design process. Do not leave the decision just on developer side. Limit the number of alternative solutions as best as possible; choose one which is the most appropriate also from future maintenance perspective.

  • SMTP POP3 & PST. Acronyms from Hades.

    - by mikef
    A busy SysAdmin will occasionally have reason to curse SMTP. It is, certainly, one of the strangest events in the history of IT that such a deeply flawed system, designed originally purely for campus use, should have reached its current dominant position. The explanation was that it was the first open-standard email system, so SMTP/POP3 became the internet standard. We are, in consequence, dogged with a system with security weaknesses so extreme that messages are sent in plain text and you have no real assurance as to who the message came from anyway (SMTP-AUTH hasn't really caught on). Even without the security issues, the use of SMTP in an office environment provides a management nightmare to all commercial users responsible for complying with all regulations that control the conduct of business: such as tracking, retaining, and recording company documents. SMTP mail developed from various Unix-based systems designed for campus use that took the mail analogy so literally that mail messages were actually delivered to the users, using a 'store and forward' mechanism. This meant that, from the start, the end user had to store, manage and delete messages. This is a problem that has passed through all the releases of MS Outlook: It has to be able to manage mail locally in the dreaded PST file. As a stand-alone system, Outlook is flawed by its neglect of any means of automatic backup. Previous Outlook PST files actually blew up without warning when they reached the 2 Gig limit and became corrupted and inaccessible, leading to a thriving industry of 3rd party tools to clear up the mess. Microsoft Exchange is, of course, a server-based system. Emails are less likely to be lost in such a system if it is properly run. However, there is nothing to stop users from using local PSTs as well. There is the additional temptation to load emails into mobile devices, or USB keys for off-line working. The result is that the System Administrator is faced by a complex hybrid system where backups have to be taken from Servers, and PCs scattered around the network, where duplication of emails causes storage issues, and document retention policies become impossible to manage. If one adds to that the complexity of mobile phone email readers and mail synchronization, the problem is daunting. It is hardly surprising that the mood darkens when SysAdmins meet and discuss PST Hell. If you were promoted to the task of tormenting the souls of the damned in Hades, what aspects of the management of Outlook would you find most useful for your task? I'd love to hear from you. Cheers, Michael

  • Understanding the SQL Server 2008 R2 Installation Center

    - by Enrique Lima
    What is available to us through those links?  Have you taken the time to explore and identify what could be useful to you? One of many gems that has come to my attention is the possibility of provisioning SQL Server to work in an image based environment (hint: Virtualization Template perhaps?!?).   Planning: Includes requirements information, documentation, how to guides, online documentation installation and other tools. Among the other tools you will find the System Configuration checker and The Upgrade Advisor. Both tools very important to ensure your deployment and installation would be successful.     Installation:  This sections focuses on getting installations going, from standalone to cluster when it comes to new instances.  Add new nodes to an existing cluster, and also perform upgrades (in this case to SQL Server 2008 R2).  Also part of this is the option to find updates available.   Maintenance: We find in this section, options that will assist us in tasks like repairing corrupt installations to removing nodes from a cluster. An option that is interesting (and we should discuss benefits later in another post) is to be able to do an Edition Upgrade, this is a feature expansion and addition based on your product installation (Developer to Enterprise, for example)   Tools:  From the System Configuration Checker to identify readiness for deployment in a successful manner, to being able to report on features installed.  And being able to run upgrades of existing packages developed in the 2005 offering to the 2008 R2 release for SSIS.   Resources: Useful and essential links to gather information and guidance.   Advanced: Here is where it gets interesting.  I break this down into 3 main groups: Installation Automation: When you install SQL Server there is a configuration file that gets dropped (ConfigurationFile.ini) that would allow for you to perform automated installations.  There are switches and options that go with this to have that process working. Cluster configuration for Sysprep: Create images that are cluster ready, 2 options, start the prep work, and then the complete once at the final destination. Stand-alone configuration for Sysprep:  Like the clustering counterpart, 2 options, prep and complete.  Giving you the option to create standard templates for your SQL Server deployments. I find it fitting that the 3 topics listed here should (and will) be additional topics I will discuss.   Options: Very clear and specific about what this means. Select the Processor Type or the Installation Media Root Path.

  • Android Array Lag?

    - by Mike
    I am making a platform game for Android. It is sort of a tile based game. I added bullets and enemies with AI and a bunch of tile types. I created a simple map with no Enemies. Everything was running well and smooth until I shot a bunch of bullets randomly everywhere. A couple of hundreds of bullets later, the FPS lowered. I made a test to find out if the bullets were the problem so I made another simple map with just a tile to stand on and left it for a while. Minutes later, I played around with it a bit to check if the FPS changed and it didnt. I reloaded the same map and shot a lot of bullets. Minutes later, the FPS was visibly lower even after the number of bullets were zero. Points to note: Programmed FPS is 30 Tested on a Samsung Galaxy Y and Samsung Galaxy W Any tile, enemy, bullet that is off screen is not drawn to prevent lag Bullets collide with Tiles (if they dont collide with in 450 frames, they are removed from the array) I used List bullets = new ListArray(); I used bullets.add(new Bullet(x, y, params...)); I used for(...){ if(...){ bullets.remove(i); } } Code for bullet: private void drawBullets(Canvas canvas) { for (int i = 0; i < bullets.size(); i++) { Bullet b = bullets.get(i); b.update(canvas); //updates physics if (b.t > blm) { //if the bullet is past its expiry bullets.remove(i); i--; } else { if (svx((b.x)) > 0 && svx(b.x) < width && svy((b.y)) > 0 && svy(b.y) < height) { // if bullet is not off screen b.draw(canvas); // draw the bullet } } } } I tried searching for solutions and references but I have no luck. I'm guessing that the lag has something to do with the Array and the Bullets or Classes that I've loaded? I'm not sure! Someone please help! Thanks in advance! :)

  • 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();     } }

  • Physics Engine [Collision Response, 2-dimensional] experts, help!! My stack is unstable!

    - by Register Sole
    Previously, I struggle with the sequential impulse-based method I developed. Thanks to jedediah referring me to this paper, I managed to rebuild the codes and implement the simultaneous impulse based method with Projected-Gauss-Seidel (PGS) iterative solver as described by Erin Catto (mentioned in the reference of the paper as [Catt05]). So here's how it currently is: The simulation handles 2-dimensional rotating convex polygons. Detection is using separating-axis test, with a SKIN, meaning closest points between two polygons is detected and determined if their distance is less than SKIN. To resolve collision, simultaneous impulse-based method is used. It is solved using iterative solver (PGS-solver) as in Erin Catto's paper. Error-correction is implemented using Baumgarte's stabilization (you can refer to either paper for this) using J V = beta/dt*overlap, J is the Jacobian for the constraints, V the matrix containing the velocities of the bodies, beta an error-correction parameter that is better be < 1, dt the time-step taken by the engine, and overlap, the overlap between the bodies (true overlap, so SKIN is ignored). However, it is still less stable than I expected :s I tried to stack hexagons (or squares, doesn't really matter), and even with only 4 to 5 of them, they hardly stand still! Also note that I am not looking for a sleeping scheme. But I would settle if you have any explicit scheme to handle resting contacts. That said, I would be more than happy if you have a way of treating it generally (as continuous collision, instead of explicitly as a special state). Ideas I have: I would try adding a damping term (proportional to velocity) to the Baumgarte. Is this a good idea in general? If not I would not want to waste my time trying to tune the parameter hoping it magically works. Ideas I have tried: Using simultaneous position based error correction as described in the paper in section 5.3.2, turned out to be worse than the current scheme. If you want to know the parameters I used: Hexagons, side 50 (pixels) gravity 2400 (pixels/sec^2) time-step 1/60 (sec) beta 0.1 restitution 0 to 0.2 coeff. of friction 0.2 PGS iteration 10 initial separation 10 (pixels) mass 1 (unit is irrelevant for now, i modified velocity directly<-impulse method) inertia 1/1000 Thanks in advance! I really appreciate any help from you guys!! :)

  • Why is my collision detection not accurate?

    - by optimisez
    After trying and trying, I still cannot understand why the leg of character exceeds the wall but no clipping issue when I hit the wall from below. How should I fix it to make him stand still on the wall? From collideWithBox() function below, it shows that playerDest.Y = boxDest.Y - boxDest.height; will get the position the character should standstill on the wall. Theoretically, the clipping effect won't be happen as the character hit the box from below works with the equation playerDest.Y = boxDest.Y + boxDest.height;. void collideWithBox() { if ( spriteCollide(playerDest, boxDest) && keyArr[VK_UP]) //playerDest.Y += 50; playerDest.Y = boxDest.Y + boxDest.height; else if ( spriteCollide(playerDest, boxDest) && !keyArr[VK_UP]) playerDest.Y = boxDest.Y - boxDest.height; } void initPlayer() { // Create texture. hr = D3DXCreateTextureFromFileEx(d3dDevice, "player.png", 169, 44, D3DX_DEFAULT, NULL, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, D3DX_DEFAULT, D3DX_DEFAULT, D3DCOLOR_XRGB(255, 255, 255), NULL, NULL, &player); playerRect.left = playerRect.top = 0; playerRect.right = 29; playerRect.bottom = 36; playerDest.X = 0; playerDest.Y = 564; playerDest.length = playerRect.right - playerRect.left; playerDest.height = playerRect.bottom - playerRect.top; } void initBox() { hr = D3DXCreateTextureFromFileEx(d3dDevice, "brock.png", 330, 132, D3DX_DEFAULT, NULL, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, D3DX_DEFAULT, D3DX_DEFAULT, D3DCOLOR_XRGB(255, 255, 255), NULL, NULL, &box); boxRect.left = 33; boxRect.top = 0; boxRect.right = 63; boxRect.bottom = 30; boxDest.X = boxDest.Y = 300; boxDest.length = boxRect.right - boxRect.left; boxDest.height = boxRect.bottom - boxRect.top; } bool spriteCollide(Entity player, Entity target) { float left1, left2; float right1, right2; float top1, top2; float bottom1, bottom2; left1 = player.X; left2 = target.X; right1 = player.X + player.length; right2 = target.X + target.length; top1 = player.Y; top2 = target.Y; bottom1 = player.Y + player.height; bottom2 = target.Y + target.height; if (bottom1 < top2) return false; if (top1 > bottom2) return false; if (right1 < left2) return false; if (left1 > right2) return false; return true; }

  • The term "interface" in C++

    - by Flexo
    Java makes a clear distinction between class and interface. (I believe C# does also, but I have no experience with it). When writing C++ however there is no language enforced distinction between class and interface. Consequently I've always viewed interface as a workaround for the lack of multiple inheritance in Java. Making such a distinction feels arbitrary and meaningless in C++. I've always tended to go with the "write things in the most obvious way" approach, so if in C++ I've got what might be called an interface in Java, e.g.: class Foo { public: virtual void doStuff() = 0; ~Foo() = 0; }; and I then decided that most implementers of Foo wanted to share some common functionality I would probably write: class Foo { public: virtual void doStuff() = 0; ~Foo() {} protected: // If it needs this to do its thing: int internalHelperThing(int); // Or if it doesn't need the this pointer: static int someOtherHelper(int); }; Which then makes this not an interface in the Java sense anymore. Instead C++ has two important concepts, related to the same underlying inheritance problem: virtual inhertiance Classes with no member variables can occupy no extra space when used as a base "Base class subobjects may have zero size" Reference Of those I try to avoid #1 wherever possible - it's rare to encounter a scenario where that genuinely is the "cleanest" design. #2 is however a subtle, but important difference between my understanding of the term "interface" and the C++ language features. As a result of this I currently (almost) never refer to things as "interfaces" in C++ and talk in terms of base classes and their sizes. I would say that in the context of C++ "interface" is a misnomer. It has come to my attention though that not many people make such a distinction. Do I stand to lose anything by allowing (e.g. protected) non-virtual functions to exist within an "interface" in C++? (My feeling is the exactly the opposite - a more natural location for shared code) Is the term "interface" meaningful in C++ - does it imply only pure virtual or would it be fair to call C++ classes with no member variables an interface still?

  • Active directory over SSL Error 81 = ldap_connect(hLdap, NULL);

    - by Kossel
    I have been several day to getting AD over SSL (LDAPS) I followed exactly this guide. I have Active Directory Certifica Service installed (stand alone Root CA), I can request cert, install certs. but whenever I want to test the connection using LDP.exe I got this famous error ld = ldap_sslinit("localhost", 636, 1); Error 0 = ldap_set_option(hLdap, LDAP_OPT_PROTOCOL_VERSION, 3); Error 81 = ldap_connect(hLdap, NULL); Server error: <empty> Error <0x51>: Fail to connect to localhost. I have been searching, I know there are many thing can cause of this error, I tried most thing I can then I decided to post it here. I tried to look if any error in system log, but nothing :/ (but I could be wwrong) can anyone tell me what else to look? UPDATE: I restarted AD service following error showed in event viewer: LDAP over Secure Sockets Layer (SSL) will be unavailable at this time because the server was unable to obtain a certificate. Additional Data Error value: 8009030e No credentials are available in the security package

  • Is there a good Lotus Notes open-source alternative?

    - by Ben S
    At my work we use Lotus Notes 6.5 for our email, meeting scheduling and instant messaging. I can't stand the horrible UI, buggy meeting scheduling and overall '90s feel when using it and would love to replace it with open-source alternatives. So far I've been able to setup Thunderbird for email, and I should also be able to configure pidgin to do IM, but I can't find any replacement for the meeting scheduling. I need to be able to receive meeting requests and respond to them. I've looked around trying to get the Thunderbird plugin Lightning to manage the scheduling, but everything I've read so far requires me to export .ics files from Lotus Notes or otherwise keep Lotus Notes around for day-to-day activities. I've also looked into using Evolution as the client, but I found even less information for it than I did for Thunderbird. How can I easily send, receive and respond to Lotus Notes meetings using an open-source alternative? Alternatively, if there exists a full drop-in replacement to Lotus Notes I would also consider it. Note: My desktop at work is a Windows XP machine, though I wouldn't be opposed to a solution requiring cygwin at this point. Edit: I have no power over the server. I only want a compatible client.

  • Dell Perc 6i with FreeBSD 8.1 errors with mfi0: COMMAND xxxxxxxx TIMEOUT AFTER xxx SECONDS

    - by jDempster
    We've recently bought two Dell PowerEdge R710 servers with Perc 6i controllers and 6x 135GB SAS Drives. We'd done some pretty extensive testing on a Dell PowerEdge R510 server with a Perc 6i and 4x 135GB SAS Drives running FreeBSD 8.1 for it's wonderful ZFS support and mfiutil. We hadn't had any problems with the R510 and had got to a point where we where happy with the performance of ZFS. Since running FreeBSD 8.1 on the R710 we've been getting errors from the RAID controller. mfi0: COMMAND 0xffffff80005d1770 TIMEOUT AFTER 6178 SECONDS This usually brings the system to a stand still. But it doesn't always happen, and performs very well up until it does happen. We've been running the disk as 3 mirrored drives striped in ZFS. So far we've noticed that running the drives with RAID10 on the RAID seems to work without errors (still testing). At first I thought hardware error as we'd been running FreeBSD on the R510 with the same controller without any issues. But both R710 have the same issue. All controllers are running the same firmware.

  • How to securely enable file sharing over PPTP on Windows 2008 Server

    - by Damage
    I have set up a Windows SBS 2003 domain (LAN) and a stand-alone Windows 2008 Server (web server) at another location (workgroup). I established PPTP VPN connection (SBS dials web server) over which users from LAN should be able to access web server. On web server I enabled TCP/IPv4 and File and Printer sharing protocol. It has a few external addresses (one of them is default) AND one local address (192.x.x.x) assigned to network adapter. Firewall allows port 445 for file sharing. There's the problem - I can not enable web server file shares to be visible to LAN users and ONLY to LAN users: From SBS I can access webserver but I cannot access webserver from LAN workstations (XP, Vista). I have had same configuration - I have just replaced old (web server) Windows 2003 server with 2008 so SBS settings are the same (static route, DNS etc.). How can I enable file sharing on web server for LAN workstations? Now I have opened File and printer sharing to the internet which is of course totaly unsecure. I tried to secure the tunnel so I moved RAS (VPN) connection (Network Center) on web server to "Private" profile and moved firewall port 445 to "Private" profile but suddenly file sharing does not work and I cannot telnet webserver on port 445. How can I secure file sharing so I do not have to open it to the internet?

  • Need an expert advice on *X display manager, window manager and composit manager combination

    - by fakemustache
    Hello! I have fought with myself whether or not i should ask this question but I find myself stuck and I need another expert opinion. I can't seem find the right combination of display and window manager (and composit manager). I have tried so many different combinations but most of them don't work for me. I have been working with Linux for a few years now and currently I'm running Gentoo with GDM, Openbox(stand alone, Gnome aware) and xcompmgr. But I have tried Metacity, Awesome and Fluxbox with and without Compiz, but always with GDM. What I want: A lightweight, HIGHLY configurable environment that doesn't rely on mouse-input too much (except for web browsing and image processing). At 95% I work with multiple consoles and desktops on multiple screens. What makes me ask is that most lightweight environments seem somewhat "unfinished" and show unexpected behavior quite often. And of course I want an environment that's not TOO ugly to look at as I use it at an average of 10 hours a day. :) Any thoughts? What do you use in a similar situation? Thanks for any advice! (Please excuse my english as I'm from Germany, btw greetings from Berlin ;)))

  • Virutal Machine loses network connectivity on Hyper V Cluster

    - by Chris W
    We're running a number of VMs on a 6 node failover cluster of blades using Hyper V. We have an intermittent issue (every few days at different times - not a fixed frequency) of VMs losing network connectivity. Console access to the VM suggests all is fine and the underlying blade has normal connectivity. To resolve the problem we either have to re-start the VM or, more usually, we do a live migration to another blade which fires up connectivity and we then migrate it back to the original blade. I've had 3 instances of this happen with a specific VM running on a particular blade however it has happened once with a different VM running on a different blade. All VMs and blades have the same basic setup and are running Windows 2008 R2. Any ideas where I should be looking to diagnose the possible causes of this problem as the event logs provide no help? Edit: I've checked that each blade is running the latest NIC drivers and all seem to be fine. Something that is confusing me - a failover or restart of the VM resolves the issue. Whilst I need to work out the underlying issue that is causing the NICs to hang I'm also concerned that the VM didn't failover to another node which would have solved the outage for me. Is there a way to configure the cluster so that it can tell that the VM guest has lost connectivity and fail it over? As things stand the cluster is assuming that the VM is running happily as I presume Hyper V says everything is great even though there is a problem.

  • Subversion and Quickbooks Files

    - by Jorge Fernandez
    I currently have a large problem on one of the file servers I manage for an Accounting Firm. Quickbooks has a tendency to create multiple files of the same thing over and over to prevent data loss. This is a good thing when you handle just a few files. But at an accounting firm it becomes a problem. Some of the older clients have 5-10 files in their respective folders, each with a different cut off date. Because of user error some of these file aren't labeled properly with their correct cutoff dates. This is where Subversion came to mind. Using the revision system would allow for 1 file to be master and have all of its revisions. Has anyone ever tried this with Quickbooks files? I've only used SVN with code for applications making each file size much smaller. How does SVN stand up with larger files like 10-25MB? I'm not exactly sure how SVN handles revisions - does it keep a duplicate of the files and duplicates the disk space space needed?

  • Outlook 2007 / 2010 Calendar: hide meetings in specific category

    - by Jeroen
    Question Is there any easy way in Outlook 2007/2010 to show/hide meetings in a specific category? Preferably only for a specific view (the Month view, in this case). Note: I was almost done writing this question, adding just one more "What I've tried" option, when I found an acceptable (though imperfect) solution. Remembering this SE blog post I figured I might as well post it after all and answer it myself. And who knows, perhaps someone else has a more elegant solution. The reason for me personally is that I'd like to hide the "small, recurring meetings" like our daily stand-up meeting in the month view. I'd prefer an Outlook feature that is meant for this (there must be one for this, right?), but I'm open to workarounds or plugin suggestions as well. What I expected to find somewhere was a list of categories (with added option "No category") where you could select/deselect from which categories you'd see meetings. Something like this mock-up: What I've tried Edit "View Settings", and use a "Filter..." on categories. This has several disadvantages, the major one is that the filter only allows me to choose what I want to show, but not what I want to hide. Even if I tick all categories but one for the filter it would still hide any uncategorized meeting. Similar to 1, but then using Advanced filters. Still a bit clumsy as changing views can be up to three clicks, but this is the best solution so far (see the corresponding answer below). Creating a sub-calendar for these "small" meetings that I wish to hide. This felt a bit clumsy and like overkill, but did provide an easy "select/deselect" option to show/hide these meetings. Search for plug-ins that do this. Couldn't find one (yet).

  • Selenium server causes crazy load on server - how to prevent?

    - by Eric
    I'm running this linux: Linux host.themepark.com 2.6.32-220.4.1.el6.x86_64 #1 SMP Tue Jan 24 02:13:44 GMT 2012 x86_64 x86_64 x86_64 GNU/Linux And I run the Selenium stand-alone server on my box with this command: java -jar /home/l/cron/selenium-server-standalone-2.24.1.jar > /logs/selenium.log 2>&1 & Here's the problem: as soon as I do that, the server load starts skyrocketing. I even went back and downloaded older versions of the Selenium server, but same results with 2.23.1, 2.23.0, and 2.19.0. Note that the server load starts going nuts before I issue ANY commands to Selenium or do anything else. All I'm doing is firing up the server, per the command above. This used to work perfectly on my server without causing massive server load, so something has changed, but I'm not sure what. My server is a managed VPS so I don't know if there is some kind of auto-update script that kicked in or what... but it's a problem. (Incidentally, even though the server load climbs like crazy, everything still works: after firing up Selenium, my server creates a screen with Xvfb so Firefox will be happy, then a PHP script talks to Selenium to do what it needs to do before shutting everything down. It takes a LONG time, and the load gets all the way up to 8 [!!!] before it is finished, which kills my web server and makes the main site horribly unresponsive... but it does get everything done.) Any suggestions for what is going on, why it's started doing this and/or, most importantly, how I can make Selenium not kill the server when it starts up... would be GREATLY appreciated!

  • Best way to mount 3-4 monitor like this?

    - by jasondavis
    I just purchased 2 HP 2009m widescreen monitors, they are not the biggest thing on the block, they are like 19-20" and are only around 150-200$ so I think they are perfect. I bought 2 of them just to make sure I like them, with the full intention of purchasing more to make either a tripple or quad display. I now I am stuck trying to decide, if I purchase 1 more to have a tripple display I would then like to just wrap the third monitor to either the rigth or left side, I could do this without a mount most likely pretty easy. If I decide to go with 2 more monitors to make a quad display then I would like to add the 2 new monitor directly above the 2 that I have now. So it would make a grid of 2 wide and 2 high. I have posted a few photos belwo to show them now with the 2 I have, you will notice that I have them tilted inwards to make more of a "V" shape instead of them being side by side and "STRAIGHT". Now if I decide to make thegrid of 4 then I will need to buy or build a stand to hold them all tightly together (no whitespace or gap between the grid of monitors) but I would like to still have both rows invert to make the slight "V". Do you know of any existing stands I could purchase that would hold all 4 monitors without making them be STARIGHT without the "V" shape? Any tips appreciated please, also they do have holes in the back for VESA. a few photos... (they are from iphone and lighting made them note very good but you can see what I am working with here)

  • Where do I connect the HDD LED wires on my RAID adapter?

    - by Giffyguy
    I'm using a Promise FastTrak TX8660 with RAID 5. The manual (and Google) just doesn't seem to explain how exactly to connect a standard two-pin HDD LED wire to the eight available pins on the card. The Manual just says - To connect your LED, follow the following diagram: The card itself resembles the diagram: But it doesn't make any sense to me. All I have is a two-pin connecter for HDD LED on the front of my computer case. I don't need anything fancy like the fault LED or seperate indicators for each drive. I just want to be able to see when my RAID 5 array is working, that's all. I don't know what the "R" and "G" stand for, but my HDD LED wires are red and white. I tried connecting the red wire to the "R" pin and the white wire to the "G" pin, but that just makes the LED on the front of my case light up indefinitely, even when the computer is idle. Which pins am I suppose to connect the HDD LED header to for basic activity indication?
