• monitor a folder and send files via ftp to clients

  - by user73109

  I am looking for software that will monitor a specific folder and when a file is created in it send that file off via ftp to a client associated with that folder by the software. I have tried software such as smart FTP and cute FTP and they don't seem to monitor folders very consistently. Some of the options with them were to write scripts to delete duplicated files from the transfer queue. I really don't want to have to write scripts for software I purchase. I am not opposed to needing scripting or writing it but I feel I shouldn't have to write scripting to make there software properly do some thing it says it does out of the box. I am currently trying to do this on a Windows XP box though running on a Server 2003 is an option if it would make things easier. I really just want pointed in the correct direction this is all fairly foreign to me

• How to educate business managers on the complexity of adding new features? [duplicate]

  - by Derrick Miller

  This question already has an answer here: How to educate business managers on the complexity of adding new features? [duplicate] 3 answers We maintain a web application for a client who demands that new features be added at a breakneck pace. We've done our best to keep up with their demands, and as a result the code base has grown exponentially. There are now so many modules, subsystems, controllers, class libraries, unit tests, APIs, etc. that it's starting to take more time to work through all of the complexity each time we add a new feature. We've also had to pull additional people in on the project to take over things like QA and staging, so the lead developers can focus on developing. Unfortunately, the client is becoming angry that the cost for each new feature is going up. They seem to expect that we can add new features ad infinitum and the cost of each feature will remain linear. I have repeatedly tried to explain to them that it doesn't work that way - that the code base expands in a fractal manner as all these features are added. I've explained that the best way to keep the cost down is to be judicious about which new features are really needed. But, they either don't understand, or they think I'm bullshitting them. They just sort of roll their eyes and get angry. They're all completely non-technical, and have no idea what does into writing software. Is there a way that I can explain this using business language, that might help them understand better? Are there any visualizations out there, that illustrate the growth of a code base over time? Any other suggestions on dealing with this client?

• Will the Driver Support for Intel HD Graphics be Improved in 12.10?

  - by Hiranya

  I recently installed Ubuntu 12.04 on a HP Pavilion dv4 laptop. This is a core i7 machine with Intel HD graphics and also a separate nVidia VGA card. I had a lot of issues getting Ubuntu 12.04 working on this system. First there were issues booting up the live CD for installation. I worked around that by using the 'nomodeset' option. Then I continued to have similar issues after installation has completed. So I had to permanently add the nomodeset option to my GRUB boot configuration. At the moment I have a working installation but there are many issues: Ubuntu GUI is a bit flaky at times. The mouse pointer goes on and off when hovering over certain icons. Certain things doesn't get rendered properly on the screen. I can't access any of the tty consoles. Hitting Ctrl+Alt+F[1-6] gives me a blank screen. And once that happens I can't even come back to the UI by hitting Ctrl+Alt+F7. I've realized that tty consoles are actually working. I just can't see the text. If I enter a command like 'sudo reboot' into the empty screen the machine reboots. Can't get external displays (monitors, projectors etc) working. But I think this is probably because the VGA out is wired to the nVidia card which is not being used by Linux. colord program crashes every now and then triggering a popup message. So my main question is, will the support for Intel HD graphics be improved in the next release? Or will I have to keep using the nomodeset option in the new release too? Also I appreciate if anybody can shed some light on any of the issues listed above. Thanks in advance.

• I can't see how a mature agile team requires any *management*?

  - by ashy_32bit

  After a recent heated debate over Scrum, I realized my problem is that I think of management as a quite unnecessary and redundant activity in a fully agile team. I believe a mature Agile team does not require management or any non-technical decision making process of whatsoever. To my (apparently erring) eyes it is more than obvious that the only one suitable and capable of managing a mature development team is their coach (and that being the most technically competent colleague with proper communication skills). I can't imagine how a Scrum master can contribute to such a team. I am having a great difficulty realizing and understanding the value of such things as Scrum and manager as someone who is not a veteran developer but is well skilled in planning the production cycles when a coach exists in the team. What does that even mean? How on earth someone with no edge-skills of development can manage a highly technical team? Perhaps management here means something else? I see management as a total waste of time and a by-product of immaturity. In my understanding a mature team is fully self-managing. Apparently I'm mistaken since many great people say the contrary but I can't convince myself.

• Is there such thing like a "refactoring/maintainability group" role in software companies?

  - by dukeofgaming

  So, I work in a company that does embedded software development, other groups focus in the core development of different products' software and my department (which is in another geographical location) which is located at the factory has to deal with software development as well, but across all products, so that we can also fix things quicker when the lines go down due to software problems with the product. In other words, we are generalists while other groups specialize on each product. Thing is, it is kind of hard to get involved in core development when you are distributed geographically (well, I know it really isn't that hard, but there might be unintended cultural/political barriers when it comes to the discipline of collaborating remotely). So I figured that, since we are currently just putting fires out and somewhat being idle/sub-utilized (even though we are a new department, or maybe that is the reason), I thought that a good role for us could be detecting areas of opportunity of refactoring and rearchitecting code and all other implementations that might have to do with stewarding maintainability and modularity. Other groups aren't focused on this because they don't have the time and they have aggressive deadlines, which damage the quality of the code (eternal story of software projects) The thing is that I want my group/department to be recognized by management and other groups with this role officially, and I'm having trouble to come up with a good definition/identity of our group for this matter. So my question is: is this role something that already exists?, or am I the first one to make something like this up?

• Cannot boot: FGLRX 8.780 + Kernel 2.6.35-25

  - by pluc

  The situation before this all happened is pretty standard. I have a HP Pavillion dv5 laptop with an ATI Mobility Radeon 4200 series. It always worked fine with Ubuntu for as long as I can remember. However, at one point, something happened and truly made a majestic mess of things. It might've been extra repos I enabled with Ubuntu Tweak - I do not know. But something made it so that my system would not boot any longer. And when I say "won't boot", this is what I mean: - Durning a normal bootup, any entries (except Windows) selected with GRUB (or BURG, not even sure which one I'm using anymore) will spawn the Ubuntu loading screen - then try to start X (or GDM) 5 times. The screen goes to dark, black and back to the Ubuntu loading screen. Then it just stays there until I spawn another TTY. I have no idea what is happening or why. There are no errors in my logs, and I'm truly at a loss here. I've linked three files: Xorg.0.log, the output of dmesg and the GDM log: Xorg.0.log: http://ubuntu.pastebin.com/tpVKc2tc dmesg: ubuntu.pastebin.com/Nd5aYj45 gdm's :0.log: couldn't post due to lack of points :( Let me know if any of you more knowledgeable folks can restore some sanity in my life. Any help is greatly apreciated.

• How to optimize a box2d simulation in action game?

  - by nathan

  I'm working on an action game and i use box2d for physics. The game use a tiled map. I have different types of body: Static ones used for tiles Dynamic ones for player and enemies Actually i tested my game with ~150 bodies and i have a 60fps constantly on my computer but not on my mobile (android). The FPS drop as the number of body increase. After having profiled the android application, i saw that the World.step took around 8ms in CPU time to execute. Here are few things to note: Not all the world is visible on screen, i use a scrolling system Enemies are constantly moving toward the player so there is alaways to force applied to their body Enemies need to collide between each others Enemies collide with tiles I also now that i can active/desactive or sleep/awake bodies. Considering the fact that only a part of the enemies are possibly displayed on screen, is there any optimizations i can do to reduce the execution time of box2d simulation? I found a guy trying an optimization based on distance of enemies from the player (link). But i seems like he just desactives far bodies (in my case, i could desactive bodies that are not visible). But my enemies need to move even when they are not visible on screen, and applying forces will not workd on inactive bodies. Should i play with sleeping bodies here? Also, enemies are composed by two fixtures and are constantly colliding with each others and with tiles but i really never need to get notified about that. Is there anything i can do to optimize this kind of scenario? Finally, am i wrong to try to run simulation at 60FPS on mobile and should i try to make it run at 30FPS?

• One way sync with either Dropbox or Google drive on linux and windows

  - by sup

  I could not google this one. I would like to use Dropbox or Google drive only as backup, so I would like to ensure I only upload to those services and never download (unless done manually via the web interface). There would be several of us uploading stuff to one account, so we would need to ensure we don't accidentaly delete something on another guy's machine by doing some changes on our local machine. Is there a simple way to do this automatically - i.e. by running a daemon that will upload eveyuthing in a given folder but never download anything? I am on linux, so that complicates things a bit, but I am also interested in windows solutions.

• Launching multiple applications with a single command/script/shortcut

  - by Bill

  I realized a few days ago that every time I sit down at work, I do a few things after unlocking my computer. First, I open up Firefox, then I open up Chrome, then I log in to Digsby. I realized I could probably save repeating this daily by writing a small batch script to open up Firefox and Chrome , but I couldn't figure out how to make it work.. and since the whole effort is to save time I don't want to bash my head around in the windows command prompt to do it. I also tired this in powershell but ran in to a bunch of security nonsense. Is there a way to do this that I am missing? Bonus points if somebody has figured out how to manipulate Digsby via COM , scripting, or python =)

• better options for screen?

  - by lonestar21

  OK. So I love screen. It has saved my bacon a few times when machines crash or get disconnected from the network. However, there are enough reasons keep keep me from using screen for everything, which include: Pain in the butt scrolling. Why can't I just interact as though this is a normal bash shell? My keyboard shortcuts are gone. I have a number of things customized in my bash environment, is there a way to get them to work in screen as well? Are there any tools our tips that I can use to make my screen-using experience as high quality as my bash using experience?

• Less daunting front end for SQL Server

  - by Martin

  We currently have a few users who have been using Access very succesfully to throw around large amounts of data. We've now got to the point where the data is just too large to be held in Access, as well as wanting to hold it in a single place where multiple users can access it. We have therefore moved the data over to SQL Server. I want to provide a general tool that they can use to view the data on the server and do some simple things like run queries and filters and export the data for offline manipulation. I don't want the support headaches that might come with rolling out SQL Management Studio, and neither do I want to have to create an Access database with links for each current database or ones that are created in the future. Can anyone recommend a simple tool that will connect to a server, list all the databases and allow a user to drill into a table and look at the data. Many thanks.

• @staticmethod vs module-level function

  - by darkfeline

  This is not about @staticmethod and @classmethod! I know how staticmethod works. What I want to know is the proper use cases for @staticmethod vs. a module-level function. I've googled this question, and it seems there's some general agreement that module-level functions are preferred over static methods because it's more pythonic. Static methods have the advantage of being bound to its class, which may make sense if only that class uses it. However, in Python functionality is usually organized by module not class, so usually making it a module function makes sense too. Static methods can also be overridden by subclasses, which is an advantage or disadvantage depending on how you look at it. Although, static methods are usually "functionally pure" so overriding it may not be smart, but it may be convenient sometimes (though this may be one of those "convenient, but NEVER DO IT" kind of things only experience can teach you). Are there any general rule-of-thumbs for using either staticmethod or module-level functions? What concrete advantages or disadvantages do they have (e.g. future extension, external extension, readability)? If possible, also provide a case example.

• Rendering multiple squares fast?

  - by Sam

  so I'm doing my first steps with openGL development on android and I'm kinda stuck at some serious performance issues... What I'm trying to do is render a whole grid of single colored squares on to the screen and I'm getting framerates of ~7FPS. The squares are 9px in size right now with one pixel border in between, so I get a few thousand of them. I have a class "Square" and the Renderer iterates over all Squares every frame and calls the draw() method of each (just the iteration is fast enough, with no openGL code the whole thing runs smootlhy at 60FPS). Right now the draw() method looks like this: // Prepare the square coordinate data GLES20.glVertexAttribPointer(mPositionHandle, COORDS_PER_VERTEX, GLES20.GL_FLOAT, false, vertexStride, vertexBuffer); // Set color for drawing the square GLES20.glUniform4fv(mColorHandle, 1, color, 0); // Draw the square GLES20.glDrawElements(GLES20.GL_TRIANGLES, drawOrder.length, GLES20.GL_UNSIGNED_SHORT, drawListBuffer); So its actually only 3 openGL calls. Everything else (loading shaders, filling buffers, getting appropriate handles, etc.) is done in the Constructor and things like the Program and the handles are also static attributes. What am I missing here, why is it rendering so slow? I've also tried loading the buffer data into VBOs, but this is actually slower... Maybe I did something wrong though. Any help greatly appreciated! :)

• How to setup email server in ubuntu 12.04LTS(debian 7 wheezy/sid) running on linode vps

  - by shihon

  I am working on email server, since i tried several times to create email server on ubuntu12.04LTS with postfix + dovecote + postfixadmin + courier + clamav + spamassassin. But everytime i install these packages i face new problems, like mails send to localhost users and found in users maildir. But I can't determine how to configure/setup for send an email to external smtp like gmail, yahoo. The most worst thing i can't determine how to use sasl, because i am not using SSL so it is not worthy for my domain.

• How to use ssh-agent (and graphic passphrase dialog) in Kubuntu 10.10?

  - by halo

  I have recently switched from Ubuntu to kubuntu, both version 10.10. Unfortunately in KDE the ssh passphrase dialog doesn't work out of the box. Everytime my ssh private key is used I need to enter my password. This is neither secure nor comfortable. I have done comprehensive research on the net but only found out dated documentation. Several things I tried didn't work out. Current status: SSH setup working with direct passphrase input ssh-agent running in X session $SSH_AUTH_SOCK set to ssh-agent's socket in X session How to enable ssh-agent for keeping the passphrase in memory for ~15mins and as a bonus always use a graphical dialog for its input? I use asymmetric SSH key pairs for pushing/pulling in Git VCS logging remotely into different server systems

• Incremental search in Visual Studio

  - by Jalpesh P. Vadgama

  Visual studio is a Great IDE and there are still lots of feature that not known to developers. Incremental search is one of them. This is a amazing feature to find code in particular document and its available from Visual Studio 2010 and carried over in Visual Studio 2012. Incremental search allows developers to search in document without blocking UI and allow to search as they type. Interesting!! right.. So let’s open visual studio and see how it works. Once you open Visual Studio and press Ctrl + I and type something it will find the string without blocking your visual studio UI. Just like following. In the above code you can see that, I have typed Cons and You can see that whole console word is highlighted. Even you can see that find dialog box on top right corner of visual studio 2012 like following. Same way if you see the footer in visual studio where it is finding cons in current document like following. Isn’t that great now we find things very easily and we don’t have to remember whole word like Console. Hope you like it. Stay tuned for more updates.

• How do I daemonify my daemon?

  - by jonobacon

  As part of the Ubuntu Accomplishments system I have a daemon that runs as well as a client that connects to it. The daemon is written in Python (using Twisted) and provides a dbus service and a means of processing requests from the clients. Right now the daemon is just a program I run before I run the client and it sets up the dbus service and provides an API that can be used by the clients. I want to transform this into something that can be installed and run as a system service for the user's session (e.g. starting on boot) and providing a means to start and stop it etc. The problem is, I am not sure what I need to do to properly daemonify it so it can run as this service. I wanted to ask if others can provide some guidance. Some things I need to ask: How can I treat it as a service that is run for the current user service (not a system service right now)? How do I ensure I can start, stop, and restart this session service? When packaging this, how do I ensure that it installs it as a service for the user's session and is started on login etc? In responding, if you can point me to specific examples or solutions I need to implement, that would be helpful. :-) Thanks! Jono

• When to use MySQL replication or DRBD for HA on Xen VM?

  - by user62513

  I'm setting up a database which needs to be needs to provide High Availabilty. My primary concern is high performance and robustness (I don't want something that will fail fast and badly). The database is accessed by the application at an average of 300 qps. It's will run on Xen VMs and it has some InnoDB tables as well as MyISAM tables. The VMs are connected via ethernet 100Mbit/s ethernet cables. Which of the two - MySQL replication or DRBD - would you recommend in such a situation? Or should I use DRBD to make the master database Highly Available and use MySQL replication on the slaves? I'm a developer so these things are all not so easy for me to make a sound judgement.

• Removing integrated video card drivers broke other hardware?

  I just purchased and installed an XFX ATI Radeon HD 4650 video card. The installation instructions said to remove the old video card drivers before installing the new driver. I did both things, but now every time I start my computer, the Found New Hardware wizard pops up for the following three devices: PCI Device SM Bus Controller Other PCI Bridge Device Furthermore, my LAN port no longer functions. The cable's connected, and the light on the port comes on, but the computer can't find any servers when I attempt to connect with it. The modem and router are working, and obviously I'm able to use the other computer here to post this. What do I do to fix this?

• Real RAM latency

  - by user32569

  Hi, very quick question. When I look for RAM timing, I got 2 different explanations on what is CAS latency. First states, its the time after command to read has been issued from CPU and data are send to data bus. Second says its time betwen column in memory layout has been activated. So, where is the truth? I mean, when I want to know total RAM latenci, in case 1, ot would be just CAS times one clock time. In second case, it would be CAS+other things like RAstoCAS and so times one clock time. Thanks.

• How to know what dll or services taskhost.exe is hosting?

  - by tigrou

  I have recently discover a new process in the task manager : taskhost.exe (maybe it was there before but i did not notice it) As the name implies, it seems to be used for running dll in background (like rundll32.exe). Is there a way to know which dll / services this process is hosting ? i would like to know for which purpose it is used and if there is some malware or not. I know it is possible to see which services svchost.exe process is hosting using process explorer utility. I have checked taskhost.exe threads and their stacks using process explorer, here is what i get : So it seems it is used for sound (winmm + playsndsrv). But there is also other things for which very few information is provided (ex : thread 1456, taskhost.exe as start address and nothing relevant can be found in stack (same for 1464, 2272 and so). So maybe it is not the right way to do.

• What's the easiest way to upgrade a single laptop hard drive?

  My HD is coming near the end of it's life and I wondered if producing an image of the original was all that was required? What's the best software to use for this and how can I accomplish it - can I use my other laptop for the image file or do I need to buy an external HD to accomplish the clone? Does having several partitions of both FAT32 and NTFS with partition magic installed affect things at all? Is it just a matter of making the image, swapping in the new HD and copying the image to that?
