• When is it ever ok to write your own development tools? (editor into IDE)

  - by mario

  So I'm foremost using a text editor for coding. It's a very bare bones editor; provides mostly just syntax highlighting. But on rare occasions I also need to debug something. And that's when I have to resort to an IDE (mostly Netbeans, but got fiddly Eclipse/Aptana working as second fallback). For general use however IDEs feel not workable to me. It's a visual thing, being used to console UIs etc. And switching back and forth between a text editor and an IDE is slightly cumbersome too. That's why I'm considering extending the editor, not really into a full-fledged IDE - but at the very least integrate a debug feature. Since I'm working on PHP, it seems not that much effort. The DBGp allows to externalize a debug handler from the editor, so it's just minor integration work and figuring out how to shoehorn a breakpoint feature into the editor (joe btw). And while I've also got time to do that, I'm wondering if this is really worthwhile. In this case it's not a needed development tool. It's just for convenience. And the cause for doing it is basically just not liking the existing solution. While over time I might extend and adapt this debugger thing, it initially will be as circumstantial as Eclipse. It inevitably starts out as poor development tool. Furthermore there is likely not much reuse. (Okay, this is not an important point. Most such software exists sans much of a use case. And also obviously, similar extensions already exist for emacs and vim, so it cannot be completely pointless.) But what's a general guideline on attempting to conoct custom development tools, particularily if they are not really needed but satisfy personal preferences? (Usability enhancement not certain.)

• How to "restart/repair" an USB port?

  - by Click Ok

  My laptop have 2 usb ports, but one is broken, so I use an USB hub in the another good USB port. In that USB hub, I use a mouse and keyboard. Suddenly, that USB port doesn't detects the mouse and keyboard (even with the light of the hub is on), and the only solution that I found is restarting the laptop. But just some minutes and the keyboard and mouse goes undetected again... So, I wonder if there is some method/software/etc to "restart/repair" the USB port without restart the PC. Thanks for all!

• Resource Acquisition is Initialization in C#

  - by codeWithoutFear

  Resource Acquisition Is Initialization (RAII) is a pattern I grew to love when working in C++.  It is perfectly suited for resource management such as matching all those pesky new's and delete's.  One of my goals was to limit the explicit deallocation statements I had to write.  Often these statements became victims of run-time control flow changes (i.e. exceptions, unhappy path) or development-time code refactoring. The beauty of RAII is realized by tying your resource creation (acquisition) to the construction (initialization) of a class instance.  Then bind the resource deallocation to the destruction of that instance.  That is well and good in a language with strong destructor semantics like C++, but languages like C# that run on garbage-collecting runtimes don't provide the same instance lifetime guarantees. Here is a class and sample that combines a few features of C# to provide an RAII-like solution: using System; namespace RAII { public class DisposableDelegate : IDisposable { private Action dispose; public DisposableDelegate(Action dispose) { if (dispose == null) { throw new ArgumentNullException("dispose"); } this.dispose = dispose; } public void Dispose() { if (this.dispose != null) { Action d = this.dispose; this.dispose = null; d(); } } } class Program { static void Main(string[] args) { Console.Out.WriteLine("Some resource allocated here."); using (new DisposableDelegate(() => Console.Out.WriteLine("Resource deallocated here."))) { Console.Out.WriteLine("Resource used here."); throw new InvalidOperationException("Test for resource leaks."); } } } } The output of this program is: Some resource allocated here. Resource used here. Unhandled Exception: System.InvalidOperationException: Test for resource leaks. at RAII.Program.Main(String[] args) in c:\Dev\RAII\RAII\Program.cs:line 40 Resource deallocated here. Code without fear! --Don

• isolate web servers on intranet with dfl-800

  - by microchasm

  I administer a small network (10 users). I'm getting ready to deploy a internal webapp that will be hosted and accessed locally only. There are about 10 users on the network (192.168.111.0/24), a win2k3 server, apache (RHEL), and Mysql (RHEL), and various miscellaneous peripheries. I'd like to isolate the apache and sql boxes into a seperate area of the lan to keep things easier to maintain/grow. I've been reading about vlans, subnets, etc.. I'm not clear, however, which would be the best solution for our setup. Thanks for any tips and or advice.

• Multithreaded Windows FOR batch command

  - by Axarydax

  Hi, do you know if there is a simple way to run FOR command in batch file on multiple threads? What's the point of having 4 cores if I can't run my tasks in 4 parallel threads? For example, if I am optimizing PNGs with PNGOUT, the command I would use is for %i in (*.png) do pngout "%i" But this is highly paralellizable task in which the sub-tasks do not depend on each other at all. To run this in 4 'queues' I'd write something like for -thread 4 %i in (*.png) do pngout "%i" Do I need to write my own for-like app that would be able to do this or is there available free solution?

• How do I get a Dell Latitude e6420 working?

  - by David_G

  I've just installed Ubuntu 12.04 (64-bit) on a brand new Dell Latitude e6420, and I'm having a few problems. This laptop has an Optimus (?) setup - i.e. integrated gfx and an Nvidia Quadro NVS 4200M. First problem - I ran setup, etc, and discovered that I can only run unity2d - If I try and login with unity3d, it just defaults to 2d. This is with nvidia-current installed (302.07). Note also that I can't run nvidia-settings ("You do not appear to be using the NVIDIA X driver."), and there is no additional drivers found ("No proprietary drivers are in use on this system"). I tried to troubleshoot this, and removed nvidia, leaving (I guess) just Nouveau drivers - In that case, unity3d did work, but I was stuck with the open source Nouveau drivers powering the integrated graphics. So, obviously, I want to run unity3d, and be using the more powerful Nvidia graphics card. I've tried a bit of tinkering around, but I'm not sure the best way to proceed, or perhaps more importantly, I'm not sure of what the best final solution might be. I've heard about bumblebee - but frankly, I would prefer to have the proprietary Nvidia drivers working properly. Any help would be much appreciated!

• Project Management Software / 1 maybe 2 developers

  - by Ominus

  I am looking for software that I can use to "manage" multiple projects (5 - 10). Here are the features I would like but any recommendation is welcome. Bug/Feature tracking on a per project basis. Some way to keep all documents, diagrams, specs, requirements, in one place with the project. Better yet a tool where all these things or most of them could be authored. Task management during the development phase with milestones and estimates/actuals. Git integration I have been doing contract work and i have been doing really well for myself as far as getting projects but its becoming VERY hard to manage everything in an efficient manner. I am trying to learn about best practices when it comes to software programming methodologies and the more I read the more i realize that I am just managing these projects poorly. I am getting things done but the more I take on the less "solid" everything is. I am afraid if I don't get some good solid tools/practices in place I am going to do my customers and myself a disservice. The problem is that there are SO many options that its hard to weed through them all. I was at a point today where I had decided that I would just code my own (there is some irony here)! Obviously everyone has their likes dislikes I would love to hear from some of you lone programmers and how you manage everything since our needs aren't exactly the same thing that a large team might need. I also want a solution that can scale to 2 maybe 3 developers if I end up hiring some people to help with my work load. Thanks again for your usual insights!

• Storing editable site content?

  - by hmp

  We have a Django-based website for which we wanted to make some of the content (text, and business logic such as pricing plans) easily editable in-house, and so we decided to store it outside the codebase. Usually the reason is one of the following: It's something that non-technical people want to edit. One example is copywriting for a website - the programmers prepare a template with text that defaults to "Lorem ipsum...", and the real content is inserted later to the database. It's something that we want to be able to change quickly, without the need to deploy new code (which we currently do twice a week). An example would be features currently available to the customers at different tiers of pricing. Instead of hardcoding these, we read them from database. The described solution is flexible but there are some reasons why I don't like it. Because the content has to be read from the database, there is a performance overhead. We mitigate that by using a caching scheme, but this also adds some complexity to the system. Developers who run the code locally see the system in a significantly different state compared to how it runs on production. Automated tests also exercise the system in a different state. Situations like testing new features on a staging server also get trickier - if the staging server doesn't have a recent copy of the database, it can be unexpectedly different from production. We could mitigate that by committing the new state to the repository occasionally (e.g. by adding data migrations), but it seems like a wrong approach. Is it? Any ideas how best to solve these problems? Is there a better approach for handling the content that I'm overlooking?

• PASS Summit Preconference and Sessions

  - by Davide Mauri

  I’m very pleased to announce that I’ll be delivering a Pre-Conference at PASS Summit 2012. I’ll speak about Business Intelligence again (as I did in 2010) but this time I’ll focus only on Data Warehouse, since it’s big topic even alone. I’ll discuss not only what is a Data Warehouse, how it can be modeled and built, but also how it’s development can be approached using and Agile approach, bringing the experience I gathered in this field. Building the Agile Data Warehouse with SQL Server 2012 http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=2821 I’m sure you’ll like it, especially if you’re starting to create a BI Solution and you’re wondering what is a Data Warehouse, if it is still useful nowadays that everyone talks about Self-Service BI and In-Memory databases, and what’s the correct path to follow in order to have a successful project up and running. Beside this Preconference, I’ll also deliver a regular session, this time related to database administration, monitoring and tuning: DMVs: Power in Your Hands http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=3204 Here we’ll dive into the most useful DMVs, so that you’ll see how that can help in everyday management in order to discover, understand and optimze you SQL Server installation, from the server itself to the single query. See you there!!!!!

• Reocurring unpack failed on git repo improted from svn

  - by xavier

  I have a git repo created from svn with git-svn. Everything converted just fine, but from time to time, when I try to git push, I get: error: unpack failed: unpack-objects abnormal exit Other repos on our server (created from scratch or imported from svn) work fine. The solution is usually to unstage, commit and push files one by one, modify the one that fails (e.g. add a whitespace or something) and commit it once again. It's obviously very irritating, for big commits it's a productivity killer - and requires a lot of server pushes. I'd be grateful for any suggestions on where to look, I couldn't google anything up.

• How do I make a backup of a live server?

  - by Jurily

  At my new job, I have a production server with the following qualities: Windows (XP I think), ancient hardware Absolutely vital database No backups whatsoever Everyone in the company has full admin rights, the passwords are stored in a .txt on the global share No installers, except for the OS The machine itself is sitting on a wooden shelf 5 feet above the ground against an external wall with frequent truck traffic on the other side; the shelf is already bent from the constant load Hasn't been rebooted in $DEITY knows how long, my predecessor wasn't even sure if it would survive it UPS is installed, but since everything is hooked up to it, it would last 10 minutes tops No spare parts or hardware budget How do I make a full backup with minimal impact on the server? I'm not sure how close it is to a total meltdown. For all I know, plugging in a USB stick could kill the company, and of course it will be all my fault, since "it was running fine before you touched it". The ideal solution would be a VM, so I have a test environment as well (separate of course).

• Moving away from PHP and running towards server-side JavaScript [on hold]

  - by Sosukodo

  I've decided to start moving away from PHP and server-side JavaScript looks like an attractive replacement. However, I'm having a hard time wrapping my head around how others are using Node.js for web applications. I'm currently using Lighttpd with FastCGI PHP. The one thing I like about PHP is that I can "inline" my scripts in the document like so: <?php echo 'Hello, World!'; ?> My question is: Is there any server-side JavaScript solution that I can use in this manor? For instance, I'd love to be able to do this: <?js print('Hello, World!'); ?> Is there such a thing? I'm not looking for opinions about "which is better". I just want to know what's out there and I'll explore each of them on my own. The important thing is that I'd like to use it like I demonstrated above. Links to the software along with implementation examples will be considered above other answers.

• Does Windows notice when a VM is moved around?

  - by Martin

  I'm thinking of migrating a Desktop machine (Windows XP) to a VM solution (VirtualBox or MS Virtual PC). The reason is that I need a new hardware anyways and I don't want to (cannot properly) reinstall all the "business" apps on there. So my plan goes as follows: I'll pull an image of the machine and restore it to a Virtual Machine using Acronis Universal Restore or some other tool that can restore to dissimilar hardware. (The process is largely irrelevant for this question I think.) Once I have this virtual machine properly running I'll move it to a new PC. So the question now is. Are there any caveats wrt. to Windows (XP?) being installed in a VM and the VM machine being moved around on different host computers? Can anything break in the OS inside the VM? Will there be troubles wrt. to Windows activation?

• Lustre - is this bad form?

  - by ethrbunny

  Im going to be consolidating several 'server rooms' into a single installation soon. Part of this effort will be finding a home for 5Tb (and growing) of files / logs. To this end Im looking at Lustre and appreciating its ability to scale. The big vendors want to sell me a $20K SAN to manage this but Im wondering about buying several iSCSI units (like this http://www.asacomputers.com/3U-iSCSI-Solution.html) and using VMs for the OSS machines. This would let me fail-over to cover problems and not require a dedicated system for each OSS. Given articles like this (http://h30565.www3.hp.com/t5/Feature-Articles/RAID-Is-Dead-Long-Live-RAID/ba-p/1422) that talk about how RAID is not keeping up with drive density Im leaning towards more disks with lower capacity each. Again - some akin to the iSCSI array above. Tell me why this is a terrible idea. Do I really need to invest in a PE710 for each OSS/OST?

• Using Postgres on Volusion site

  - by Sean

  Okay, I apologize if this is so basic that I should know the answer, but I'm not sure where else to go for the solution. I would like to start a small store site using Volusion. I would like some custom ASP code to query data that I currently have in a Postgres database. I would like to be able to just move the database file(s) onto the Volusion server via ftp and access them from my store site (via the custom ASP). Do I need to install Postgres onto the server to do this, or can I just ftp my database file(s) and access them with the ASP code? I think I need to install Postgres, but would like to do this without such an installation if possible.

  This is my first time developing Android applications. I'm developing an Android app on Eclipse on Windows 7. I would like to run the Android app from the Windows 7 command line interface. I have my Android device connected to the PC. The workspace directory that I use to store the Android project is C:\Users\Guest\Desktop\Software Applications Development\Java\Android Moblie Applications Projects\Eclipse Indigo for Java EE x64-bit\project workspace I opened the command line interface and I changed the working directory to the Android workspace directory. cd C:\Users\Guest\Desktop\Software Applications Development\Java\Android Moblie Applications Projects\Eclipse Indigo for Java EE x64-bit\project workspace I included Android sdk platform tools directory into the PATH environment variable. c:\Users\admin\Android-sdks\platform-tools Then I entered this into the Windows 7 command line interface: ant debug I have this error message on the cmd: ant is not recognised as an internal or external command, operatable program or batch file. What is the solution to this problem?

• Alternatives to Citrix GoToAssist ?

  - by Evan Carroll

  Citrix GoToAssist is a really nifty little web application for customer support that allows you to take control of someones OSX, or Windows machine. Essentially, it works likes this: You log in to your management console You get a code You give them a code, and a website (fastsupport.com) They go there and enter in the code They accept the browser applet which installs a program on their computer You have control of their desktop You can see their desktop, configure applications, etc. They can also see when you disconnect. It is really rather nifty, but it doesn't support Linux and it is rather expensive (660$ a year). Does anyone know of any alternatives to this? I'm looking for a solution as simple on the user as this one, that doesn't require firewall configuration or setting up ssh/vnc/rdesktop etc.

• Dediced server for all network functions?

  - by Alan

  I want to set up a fictional network configuration for a school in my neighborhood. They have about 50 computers altogether, 2X20 in computer rooms for students and another 10 scattered around for various professors. They should all access the internet through a dedicated Linux router machine. What they would like is to have domain names for those three computer groups. Lab1, Lab2 and Professors. The computers in Lab2 and Lab1 should have static ip and should all be named by numbers. So there should be 1@Lab1, 2@Lab1.... etc. And the Professors network should have a DHCP, with authentication. Is it an ok solution to have all these functions on a single server? (The one which will be used as a router) Do I have to set a local DNS for domain naming? Do the host names for Lab computers have to be set on the clients, or can they be automatically assigned?

• Internet problems

  I've got problems on my freshly installed windows Xp machine. I cannot connect to the internet and I've tried various 'solutions' provided to me by the help and support center. Surprisingly none of them worked... Anyways, I've got 3 pc's next to me sharing a lan which is connected to the internet though a modem. The computer I use right now uses windows xp aswell and runs without any problems. I've tried everything on not working computer. I've ran the connection wizard several times, but it's not working :( Also I've very little experience with this version of windows, so I'm sorry if the solution is obvious.

• Is there a way to set up message moderation in Exchange 2007?

  - by Nate Pinchot

  Is there a way to get a feature in Exchange 2007 similar to message moderation in Exchange 2010 through the use of third party tools or otherwise? I've Googled things like "exchange 2007 outbound email approval" to no avail. We are working on getting Exchange 2010 implemented but I need an interim solution if at all possible. The reason for this is from a customer service perspective. I am willing to use a small process to be a smart host if needed. I would appreciate any suggestions or advice. Edit: My apologies, I should have been more clear that I am trying to moderate/approve outgoing email from certain users, not moderate/approve email sent to a distribution group.

• How can I disable the beep when I plug in/unplug my laptop's AC adapter?

  - by Dunaril

  My Packard-Bell laptop is emitting a loud, annoying beep when I connect or disconnect it to/from an AC power source. Whether I have headphones plugged in or not does not change anything; the sound goes out of the speakers and wakes everyone up. Do you know of any ways to eliminate this sound? I searched around the Internet and found a solution involving setting a specific volume bar to 0 in the playback settings, but I did not find it on my laptop. I am using Windows 7.
