• MySQL Locking Up

  - by Ian

  I've got a innodb table that gets a lot of reads and almost no writes (like, 1 write for every 400,000 reads approx). I'm running into a pretty big problem though when I do INSERT into the table. MySQL completely locks up. It uses 100% cpu, and every single other table (in other databases even) have their statuses set to "Locked" until the INSERT is done. This is a big problem because MySQL stays locked up for up to 4 minutes. I'm using version 5.1.47 (rpm from mysql.com). Any ideas?

• Program can't start because dll is missing

  - by Kruug

  Any executable that I attempt to run on this laptop pops up an error stating The program can't start because LPK.dll is missing from your computer. Try reinstalling the program to fix this problem. I have tried doing regsvr32 lpk.dll from within system32, but that returns the error The module "lpk.dll" was loaded but the entry-point DLLRegisterServer was not found. Make sure that "lpk.dll" is a valid DLL or OCX file and then try again. I was able to copy the DLL file from a working computer, but I get the same issue. How would I go about registering this DLL? Or, alternatively, which program would I have to reinstall to get the DLL to work again? The system is Windows 7 Professional 64-bit with Service Pack 1. I would really like not to reinstall the OS, but at this point, I'm about ready to.

• How to divide work to a network of computers?

  - by Morpork

  Imagine a scenario as follows: Lets say you have a central computer which generates a lot of data. This data must go through some processing, which unfortunately takes longer than to generate. In order for the processing to catch up with real time, we plug in more slave computers. Further, we must take into account the possibility of slaves dropping out of the network mid-job as well as additional slaves being added. The central computer should ensure that all jobs are finished to its satisfaction, and that jobs dropped by a slave are retasked to another. The main question is: What approach should I use to achieve this? But perhaps the following would help me arrive at an answer: Is there a name or design pattern to what I am trying to do? What domain of knowledge do I need to achieve the goal of getting these computers to talk to each other? (eg. will a database, which I have some knowledge of, be enough or will this involve sockets, which I have yet to have knowledge of?) Are there any examples of such a system? The main question is a bit general so it would be good to have a starting point/reference point. Note I am assuming constraints of c++ and windows so solutions pointing in that direction would be appreciated.

• Restoring a Windows 7 backup onto Server 2008 R2

  - by Colin Desmond

  I have recently moved my main machine from Windows 7 to Server 2008 R2. Just before I did the install, I used the Windows Backup facility to create a backup on a file share. I am now using the Server Backup facility in 2008 R2 to restore this and it is not working. When I use another Win7 machine, I point the restore program at the folder containing the backup fileset and it lets me look through them. In R2, I point it at the same folder and it tells me that "The specified remote share does not contain any backup." I naively assumed that the two systems would be compatible, is this not the case? Is there anyway to get that data back again?

• Domain Controller Placement

  - by Matt

  I've been working through some Exchange training documentation (the official MS e-learning package) and all of the design scenarios allude to placing at least one DC from your forest root domain in every site. I'm not sure whether this just relates to Exchange, but I can think of a number of issues we experience in our forest that would be resolved by this. For example, a Microsoft support engineer has stated that EVERY client in a child domain (i.e. all workstations and member servers) need access to a forest root DC to check certificate/template permissions, even on a subordinate CA. I have attempted to locate documentation or guidelines from Microsoft on this, but have not been able to find anything. I found the Domain Controller Placement guide, but it's only a form - you would use it to document where you will place your DCs, but it doesn't give any guidance on where you should deploy them. Does anyone know where, or if, I can find any such documentation?

• Checking for collisions on a 3D heightmap

  - by Piku

  I have a 3D heightmap drawn using OpenGL (which isn't important). It's represented by a 2D array of height data. To draw this I go through the array using each point as a vertex. Three vertices are wound together to form a triangle, two triangles to make a quad. To stop the whole mesh being tiny I scale this by a certain amount called 'gridsize'. This produces a fairly nice and lumpy, angular terrain kind of similar to something you'd see in old Atari/Amiga or DOS '3D' games (think Virus/Zarch on the Atari ST). I'm now trying to work out how to do collision with the terrain, testing to see if the player is about to collide with a piece of scenery sticking upwards or fall into a hole. At the moment I am simply dividing the player's co-ordinates by the gridsize to find which vertex the player is on top of and it works well when the player is exactly over the corner of a triangle piece of terrain. However... How can I make it more accurate for the bits between the vertices? I get confused since they don't exist in my heightmap data, they're a product of the GPU trying to draw a triangle between three points. I can calculate the height of the point closest to the player, but not the space between them. I.e if the player is hovering over the centre of one of these 'quads', rather than over the corner vertex of one, how do I work out the height of the terrain below them? Later on I may want the player to slide down the slopes in the terrain.

• xinet vs iptables for port forwarding performance

  - by jamie.mccrindle

  I have a requirement to run a Java based web server on port 80. The options are: Web proxy (apache, nginx etc.) xinet iptables setuid The baseline would be running the app using setuid but I'd prefer not to for security reasons. Apache is too slow and nginx doesn't support keep-alives so new connections are made for every proxied request. xinet is easy to set up but creates a new process for every request which I've seen cause problems in a high performance environment. The last option is port forwarding with iptables but I have no experience of how fast it is. Of course, the ideal solution would be to do this on a dedicated hardware firewall / load balancer but that's not an option at present.

• What is the value of workflow tools?

  - by user16549

  I'm new to Workflow developement, and I don't think I'm really getting the "big picture". Or perhaps to put it differently, these tools don't currently "click" in my head. So it seems that companies like to create business drawings to describe processes, and at some point someone decided that they could use a state machine like program to actually control processes from a line and boxes like diagram. Ten years later, these tools are huge, extremely complicated (my company is currently playing around with WebSphere, and I've attended some of the training, its a monster, even the so called "minimalist" versions of these workflow tools like Activiti are huge and complicated although not nearly as complicated as the beast that is WebSphere afaict). What is the great benefit in doing it this way? I can kind of understand the simple lines and boxes diagrams being useful, but these things, as far as I can tell, are visual programming languages at this point, complete with conditionals and loops. Programmers here appear to be doing a significant amount of work in the lines and boxes layer, which to me just looks like a really crappy, really basic visual programming language. If you're going to go that far, why not just use some sort of scripting language? Have people thrown the baby out with the bathwater on this? Has the lines and boxes thing been taken to an absurd level, or am I just not understanding the value in all this? I'd really like to see arguments in defense of this by people that have worked with this technology and understand why its useful. I don't see the value in it, but I recognize that I'm new to this as well and may not quite get it yet.

• Should all public methods in an abstract class be marked virtual?

  - by Justin Pihony

  I recently had to update an abstract base class on some OSS that I was using so that it was more testable by making them virtual (I could not use an interface as it combined two). This got me thinking whether I should mark all of the methods that I needed virtual, or if I should mark every public method/property virtual. I generally agree with Roy Osherove that every method should be made virtual, but I came across this article that got me thinking about whether this was necessary or not. I am going to limit this down to abstract classes for simplicity, however (whether all concrete public methods should be virtual is especially debatable, I am sure). I could see where you might want to allow a sub-class to use a method, but not want it overriding the implementation. However, as long as you trust that Liskov's Substitution Principle will be followed, then why would you not allow it to be overriden? By marking it abstract, you are forcing a certain override anyway, so, it seems to me that all public methods inside of an abstract class should indeed be marked virtual. However, I wanted to ask in case there was something I might not be thinking. Should all public methods within an abstract class be made virtual?

• Wow is very faster on GNOME Shell comparing to unity

  - by João Vinholi

  I have been trying to run WoW on ubuntu 12.04. When I run it on unity, the frame rate is very low and it is impossible to play. Although, when I launch it on gnome shell, for some reason, the frame rate gets very high and the playing experience is very comfortable. The problem is that I prefer running unity instead of gnome shell, but I like to play WoW too. Is there a way to run WoW on unity, with no lag?

• Search Engine Marketing Tools the Best Means For Better Ranking on Search Engine Result Pages

  For any website a better ranking on the search engine result pages is the most desired thing. And for that reason there is a huge competition to get within the top ten ranking on the result pages. The point behind this is that when a website gets within the top ten ranking on the result pages it is most likely that the site would receive more visitors than the sites on the later pages.

• Image storage social network (Host plan)

  - by Samir

  I'm wondering what the best way is to host images on a social network site. Let's say that I expect my social network to reach 500.000 users in 2 years time. That would mean that if every user uploaded about 100 images and every image is 1 MB that I will have to need: 500.000 * 100 * 1 MB = 50.000.000 MB which means 50 terabytes. I'm not sure how I can best setup my hosting plan in order to have a solid bases to store my images and eventually store video files as well. Which hosting plan would you recommend me to start with and how can I enhance the plan?

• Does an LTS desktop get any updates after three years?

  - by Oli

  In cleaning up an answer today, I noted the following: LTS desktops get updates for three years LTS servers get updates for five years An Ubuntu desktop is (essentially) a superset of server packages. So in the fourth and fifth year, if LTS Server gets Kernel updates*, are these also provided for LTS Desktop? What about other core-system stuff? I realise the Kernel is a little special because there is a -server variant but are updates pushed for -generic (et al) too?

• Tracking down memory issues affecting a website

  - by gaoshan88

  I've got a website (Wordpress based) that became unresponsive. I SSH'd into the server and saw that we were out of memory. Errors in my apache log files indicated the same... things failing to be allocated due to lack of memory). Restarting the server fixes it. So I look in access.log and error.log around the time of the incident but I see nothing strange. No extra traffic, no unusual requests. In fact the only request around the time of the problem was one from Googlebot for an rss feed... at that point I start to see 500 response codes in the logs until the machine was rebooted. I look in message.log hoping to see something but there is nothing at all for that entire day (which is odd as there are entries for every other day). The site has a large amount of memory allocated to it and normally runs using about 30% of what is available. My question... how would you go about trying to track this down at this point? What are some other log files I could check or strategies I could take?

• incorrect DNS entries on server 2008 r2

  - by user137841

  On the main DC (windows server 2008 R2 standard) in our network I have to clear some old DNS entries every now and then in the Forward and Reverse Lookup Zones. I have set the server Aging/Scavenging settings to Scavenge stale resource records, with both the No-refresh interval and Refresh interval to 5 days. Yet every now and then I still have to logon to the sever and remove the DNS entries for computers that is not part of the domain anymore or has been renamed ect. Is there a different way to automatically remove the old entries?

• Fast, reliable data transfers from/to China

  - by Nils

  We are a small company and we will need to transfer rather large amounts of data (10GB+ each time) between Europe and China in the near future. As many may have experienced, Internet connections to or from China can be rather unreliable and slow at times without any apparent reason. For example, while sending data to China via FTP generally works well, it can be painfully slow in the other direction. Currently, we are investigating new ways to have high transfer rates in both directions. So far we have tried: FTP (see above) FTP over VPN services (generally slower than direct connections) F2F (like Retroshare or Freenet - slow!!) Aspera (fast but expensive!) BitTorrent (unreachable end nodes, b/c of firewalls which we must not configure) We would like to try: Cloud storage (e.g. Amazon S3, Google Storage) - are those services always and reliably reachable from inside China? Point-to-Point VPN (currently not possible, b/c of the network, see above) I'd be especially grateful to hear from people who have already dealt with this kind of problem before.

• What are differences between sell side platforms (Admeld) and self-serve platform (AdReady)?

  I was confused with sell side platforms (e.g. Admeld) and self-serve platforms (e.g. AdReady) as both are serving services to publishers. I would like to know the differences in order to get the answer of "which platform is suitable for a medium size website publisher, and why?" references: http://en.wikipedia.org/wiki/Sell_Side_Platform. http://www.masternewmedia.org/self-serve-advertising-services-guide-to-the-best-do-it-yourself-ad-management-platforms/.

• What programming language(s) could I develop this app with for an iPhone

  - by Keon Davies

  The app I'm thinking of making would be little similar to fruit ninja. The app/ game would involve different types of animals flying straight at and you have to choose the right item to catch the animal before he gets to you. For example to capture a fish you would have to select the net and then click on the fish to capture it. Also I would like to have a leader board too. Which programming language(s) could I use to develop what I just described?

• Memory allocation strategy for the vertex buffers (DirectX 10/11)

  - by Alex

  I have the following question. I write CAD system. So I have a 3D scene and there are many different objects (walls, doors, windows and so on). User can add or delete some objects. The question is: how can I organise the keeping of vertices for all my objects. I can create vertex buffer for every object. But I think drawing/switching from one buffer to another would have performance penalty. Another way - I can create several big buffers for every object type. But I don't understand how to update such buffers. It is too big to update whole buffer (for example buffer for all walls). What I need to do if I want to delete the object from the middle of the buffer? Actually I have the similar question: http://stackoverflow.com/questions/5515700/how-to-properly-update-vertex-buffers-in-directx-10 Most examples I've found work with very static models. Therefore, they tend to create a single vertex buffer with their list of points, and then are just manipulated by matrix transformations. I, on the other hand, will be updating the scene very often.
