• How important do you find exception safety to be in your C++ code?

  - by Kai

  Every time I consider making my code strongly exception safe, I justify not doing it because it would be so time consuming. Consider this relatively simple snippet: Level::Entity* entity = new Level::Entity(); entity->id = GetNextId(); entity->AddComponent(new Component::Position(x, y)); entity->AddComponent(new Component::Movement()); entity->AddComponent(new Component::Render()); allEntities.push_back(entity); // std::vector entityById[entity->id] = entity; // std::map return entity; To implement a basic exception guarantee, I could use a scoped pointer on the new calls. This would prevent memory leaks if any of the calls were to throw an exception. However, let's say I want to implement a strong exception guarantee. At the least, I would need to implement a shared pointer for my containers (I'm not using Boost), a nothrow Entity::Swap for adding the components atomically, and some sort of idiom for atomically adding to both the Vector and Map. Not only would these be time consuming to implement, but they would be expensive since it involves a lot more copying than the exception unsafe solution. Ultimately, it feels to me like that time spent doing all of that wouldn't be justified just so that the a simple CreateEntity function is strongly exception safe. I probably just want the game to display an error and close at that point anyway. How far do you take this in your own game projects? Is it generally acceptable to write exception unsafe code for a program that can just crash when there is an exception?

• Minimize useless tweaking of a numeric app

  - by Potatoswatter

  I'm developing a numeric application (nonlinear optimizer), with a zillion knobs to tweak and rising. It's not my first foray into this domain, but this time there are even more variables in the code and I'm on a tight schedule. Don't want to waste time fiddling. Days or even months can potentially be wasted adjusting variables, recompiling, and reprocessing benchmark datasets. The resulting data is viewed and trouble spots are checked. The overall quality of the solution is reported by the program but the meaning of the report could change over time. (Numeric units for the report are one thing I'm trying to nail down.) One main problem is organizing result files to identify each with specific code changes. Note taking can be a pain, is there software to help with this? Are there agreed best practices to making this kind of development cycle reliably move forward? The solver package converges to its optimal solution with mechanical determination, but I'm all too familiar with the way an excess of design decisions can mire development.

• Merging multiple top-level domains into a single domain

  - by user23089

  My client had multiple top-level-domains. Each one represented an insurance program within a specific vertical. For all the sites at these alternate domains, there was a 30/70 mix of duplicate vs. original content. Some of the alternate domains ranked very well for their target keyphrase groups, where others were absent in results pages. We advised the client to merge multiple domains into their existing main domain, for usability and SEO reasons. We recently ran the merger. Here was our process: On the main domain, transfer the content such that it matches 1-for-1 content on the various alternate domains Setup Google Webmaster Tools on the main domain Push the new content on the main domain live and submit a corresponding sitemap to Google Establish 301 redirects on the alternate domains, such that each alternate domain URL points to its respective page on the main domain We did this 12 days ago, and pages (previously on the alternate domains) that had ranked well on Google have now plummeted or are entirely non-existent. Did we do the right thing by merging multiple top-level domains into a single domain? Is this initial dip in rankings normal? How soon should we expect to see it return to its normal rankings?

• Is there an established or defined best practice for source control branching between development and production builds?

  - by Matthew Patrick Cashatt

  Thanks for looking. I struggled in how to phrase my question, so let me give an example in hopes of making more clear what I am after: I currently work on a dev team responsible for maintaining and adding features to a web application. We have a development server and we use source control (TFS). Each day everyone checks in their code and when the code (running on the dev server) passes our QA/QC program, it goes to production. Recently, however, we had a bug in production which required an immediate production fix. The problem was that several of us developers had code checked in that was not ready for production so we had to either quickly complete and QA the code, or roll back everything, undo pending changes, etc. In other words, it was a mess. This made me wonder: Is there an established design pattern that prevents this type of scenario. It seems like there must be some "textbook" answer to this, but I am unsure what that would be. Perhaps a development branch of the code and a "release-ready" or production branch of the code?

• Exchange 2013 Virtual Machine: Backup just mailboxes and clear logs

  - by Ben Curtis

  I have a Windows Server 2012 machine running Exchange 2013 running as a KVM virtual machine. For my VM guests, I do full image based backups from the host, so that I can quickly restore to any host server simply by copying over the disk image files. This means I don't need a nightly full system backup. That being said, without running a VSS Full Backup, the Exchange logs get massive (Specifically, the performance logs which are 500MB a day). In addition, I would also like to have a nightly backup of just the mail database. What is the best way to accomplish this? A full backup of the C:\Program Files\Microsoft\Exchange Server\V15 folder as I found in one tutorial did not clear out the logs. Thanks, Ben

• How to refactor while keeping accuracy and redundancy?

  - by jluzwick

  Before I ask this question I will preface it with our environment. My team consists of 3 programmers working on multiple different projects. Due to this, our use of testing is mostly limited to very general black box testing. Take the following assumptions also: Unit Tests will eventually be written but I'm under strict orders to refactor first Ignore common Test-Driven Development techniques when given this environment, my time is limited. I understand that if this were done correctly, our team would actually save money in the long-term by building Unit-Tests before hand. I'm about to refactor a fairly large portion of the code that is critical. While I believe my code will accurately work when done and after our black box testing, I realize that there will be new data that the new code might not be able to handle. What I wanted to know is how to keep old code that functions 98% of the time so that we can call those subroutines in case the new code doesn't work properly. Right now I'm thinking of separating the old code in a separate class file and adding a variable to our config that will tell the program which code to use. Is there a better way to handle this? NOTE: We do use revision control and we have archived builds so the client could always revert to a previous build, but I would like to see if there is a decent way of doing this besides reverting. I want this so they can use the other new functionality delivered in the new build. Edit: While I agree I will need to write Unit Tests for this, I don't believe I will capture everything with them. I'm looking for ways to easily be able to revert to the old, functional code should anything happen. While I know this is a poor practice, I'm planning on removing this code after our team can guarantee that the new code works to the same standards as the old.

• Flame Experiments Aboard the ISS Yield Surprising Results

  - by Jason Fitzpatrick

  Recent flame-based experiments aboard the International Space Station yielded results scientists simply thought couldn’t happen–combustion in microgravity is a curious thing. Smithsonian magazine reports on the findings: Here on Earth, when a flame burns, it heats the surrounding atmosphere, causing the air to expand and become less dense. The pull of gravity draws colder, denser air down to the base of the flame, displacing the hot air, which rises. This convection process feeds fresh oxygen to the fire, which burns until it runs out of fuel. The upward flow of air is what gives a flame its teardrop shape and causes it to flicker. But odd things happen in space, where gravity loses its grip on solids, liquids and gases. Without gravity, hot air expands but doesn’t move upward. The flame persists because of the diffusion of oxygen, with random oxygen molecules drifting into the fire. Absent the upward flow of hot air, fires in microgravity are dome-shaped or spherical—and sluggish, thanks to meager oxygen flow. “If you ignite a piece of paper in microgravity, the fire will just slowly creep along from one end to the other,” says Dietrich. “Astronauts are all very excited to do our experiments because space fires really do look quite alien.” Hit up the link below for the full article including how NASA is applying the findings.

• On an unencrypted public wi-fi hotspot, what exactly is a packet sniffer doing to get another computer's packet?

  - by hal10001

  I get mixed results when reading information security articles, some of them stating that in order to do something similar you need to also setup some sort of honeypot with a running access point and local Web server to intercept traffic. Then other articles seem to indicate you don't need that, and you can just run Wireshark, and it will detect all packets being sent on the network. How could that be, and what exactly is a packet sniffer doing to get those packets? Does this involve intercepting wireless signals transmitted over the wireless protocol and frequency via the NIC on the computer running a program like Wireshark?

• what software will rip a CD to flac files in one step?

  - by jcollum

  I'm using EAC to rip files to FLAC. Seems fine. But for a large amount of CDs (200 or so) the process is a little labor intensive. There's 4 or 5 clicks in there that seem extraneous -- EAC seems to want to rip the CD to a set of WAV files then (after all those files are ripped) I have to select "Process WAV files" (I'd get it exact, but EAC is occupied right now). I'd like to send all of it to FLAC files in just a few steps: get cddb info, select art, rip. Is there a way to do this with EAC that I'm missing? Haven't been able to find anything on the web that explains this. Is there a better program for this?

• Quiet Sound while recording using the "Stereo Mix" option on Windows XP.

  - by DragoonX

  I'm trying to record some of my work, and the video capture program I'm using works fine. It's HyperCam2, and since it's not really professional, I don't care about that little thing in the corner. Anyways, If I check the record sound option and put it on the highest quality, and I want it to record the sounds playing from my computer, I have it record the "Stereo Mix" setting. However, after a quick test, I saw that even though my computer was at max volume, the recorded sound was very quiet, almost inaudible. Thinking it was just HyperCam, I downloaded Audacity, and only met similar results. While I'm not entirely savvy with hardware, I BELIEVE this to be my soundcard: SoundMAX Integrated Digital HD Audio

• Distinct operator in Linq

  - by Jalpesh P. Vadgama

  Linq operator provides great flexibility and easy way of coding. Let’s again take one more example of distinct operator. As name suggest it will find the distinct elements from IEnumerable. Let’s take an example of array in console application and then we will again print array to see is it working or not. Below is the code for that. In this application I have integer array which contains duplicate elements and then I will apply distinct operator to this and then I will print again result of distinct operators to actually see whether its working or not. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Experiment { class Program { static void Main(string[] args) { int[] intArray = { 1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 5 }; var uniqueIntegers = intArray.Distinct(); foreach (var uInteger in uniqueIntegers) { Console.WriteLine(uInteger); } Console.ReadKey(); } } } Below is output as expected.. That’s cool..Stay tuned for more.. Happy programming. Technorati Tags: Linq,Distinct

• how to split a pcap file into a set of smaller ones

  - by facha

  I have a huge pcap file (generated by tcpdump). When I try to open it in wireshark, the program just gets unresponsive. Is there a way to split a file in set of smaller ones to open them one by one? The traffic captured in a file is generated by two programs on two servers, so I can't split the file using tcpdump 'host' or 'port' filters. I've also tried linux 'split' command :-) but with no luck. Wireshark wouldn't recognize the format.

• Setting different default applications for different Desktop Environment

  - by Anwar

  I am using Ubuntu 12.04 with default Unity interface. I installed later the KDE desktop, XFCE, LXDE, gnome-shell and Cinnamon. The KDE comes with different default applications than Unity, such as kwrite for text editing, konsole as virtual terminal, kfontview for font viewing and installing, dolphin as File browser etc. Other DE come with some other default applications. The problem arises when you want to open a file such as a text file, with which can both be opened by gedit and kwrite, I want to use kwrite on KDE and gedit on Unity or Gnome. But, there is no way to set like this. I can set default application for text file by changing respective settings in both KDE and Unity, but It become default for both DE. For example, If I set kfontviewer as default font viewing application in KDE, it also opens fonts when I am in Unity or Gnome and vice versa. This is a problem because, loading other DE's program takes long time than the default one for the used DE. My question is: Can I use different default applications for different DE? How?

• In IIS why do HTTP requests use the host header, and FTP requests do not

  - by Keeno

  So.... In IIS, if you use the in-build FTP you need to combine the FTP host header in the FTP username e.g. www.hello.com|domain/username So, the FTP program gets its "hook" from the username. However, you can connect to the FTP site using www.hello.com:21 over the FTP port. Why then, doesnt the FTP service work the same way as the HTTP service? IIS knows what site to serve back based on the host header after all.... Thanks!

• How to play an MKV 3D side-by-side video?

  - by djechelon

  I have a video in Matroska format (MKV, file extension .mkv), 3D half-SBS, where the 1280x720 frame shows the left-eye frame on the left and the right-eye frame on the right. I don't have a 3DTV, but I have NVidia 3D Vision: I tried to open it with PowerDVD 10 with no result (program hangs). With the same PowerDVD, I tried to play the Avatar 3D trailer downloaded from YouTube (MP4 format), but it now shows it the two frames. PowerDVD 10 is advertised to support 3D and 3D Vision. Why can't I play these videos? NVidia Stereoscopic player plays the Avatar trailer fine, but it doesn't support MKV.

• How can I force Parallels' networking to obtain an IP through a wireless router?

  - by RLH

  Here is my setup. I have a Macbook, Thunderbolt display and an Ethernet connection plugged into the Thunderbolt display. During the day, most of my network use can (and should) operate across the ethernet associated with my display. However, I also need to be able to connect up to a wireless router. This hasn't been a problem on the Mac OS X side, but the program that I need to run on the router has to obtain an IP address from the wireless access point. Considering my current setup, how can I leave it so that I can access the internet in OS X, yet have my Window 7 instance running in Parallels, get it's assigned IP address from a wireless router that my Mac is also connected to? I've fiddled around with the Parallel's network settings for an hour, and I can't get Parallel's to see the router, even though my Mac is certainly connected to it.

• Malicious Software

  - by Bb

  I had a program created for me recently and didn't really think about it being executable posing a threat since I pretty much trust the source but not completely. I then thought about the fact that a keylogger, or any kind of spyware or malicious software could've been possibly binded to it. This made me wonder about all the other stuff I download daily from places or people (torrents) I don't think twice about. My question is, how can someone find out if there has been some sort of keylogger binded to the software you're running or other things binded? What are some good ways to find out and stop these things?

• Good free OCR with GUI for correcting mistakes? (for Windows)

  - by Hugh Allen

  I've used SimpleOCR, which has a nice GUI for correcting mistakes. Unfortunately it makes a lot of mistakes! (and suffers other bugs and limitations) On the other hand Tesseract is more accurate but has no GUI at all. Is there a free OCR program for Windows which has a nice GUI and a low error rate? I want it to highlight suspect words (by OCR uncertainty, not just spell checking) and show the original (bitmap) word while I'm editing the OCRed word similar to what SimpleOCR does. Open-source would be best, followed by freeware, then trial / demo / crippleware a long way behind.

  - by user63411

  Possible Duplicate: How do you find a new software to download? I see that the most time I spend on the computer I lose to just searching for suitable software. How you do it? What is your way to find software? Do you first go to a forum or google? Which torrent site? which P2P program, website or server? For example: "I need a software that have functions as a remote desktop and also lets you copy and paste (drag and drop - file manager). And after few hours searching on Google I downloaded LOGMEIN Pro2, but than I see that is just trial. So if I need to find alternative I will spend another whole day. Where to go? I am not an amateur but I need a better system. I need better introduction on how to find what is the suitable software.

For some reason when I shutdown Ubuntu the Foobar2000 process is ended abnormally in Wine and when it runs next time I get an annoying "start in safe mode?" message. Not a huge problem, but I'd like it fixed. The safe mode message only appears if a file called "running" is present when Foobar2000 starts (if it isn't deleted when closed properly). So by deleting "running" then starting Foobar2000, the message doesn't appear. I thought it would be easy enough to enter this as a startup command, however it doesn't want to work. The command I am using is rm '/home/henry/.wine/drive_c/users/henry/Application Data/foobar2000/running';'/home/henry/.wine/drive_c/Program Files (x86)/foobar2000/foobar2000.exe' which works fine if I just run it from terminal, the file is deleted then foobar2000 runs. Does anyone know why this isn't working at startup? Also, will this run with a terminal visible? How can I make just the gui appear? Thanks
