• C++0x implementation guesstimates?

  - by dsimcha

  The C++0x standard is on its way to being complete. Until now, I've dabbled in C++, but avoided learning it thoroughly because it seems like it's missing a lot of modern features that I've been spoiled by in other languages. However, I'd be very interested in C++0x, which addresses a lot of my complaints. Any guesstimates, after the standard is ratified, as to how long it will take for major compiler vendors to provide reasonably complete, production-quality implementations? Will it happen soon enough to reverse the decline in C++'s popularity, or is it too little, too late? Do you believe that C++0x will become "the C++" within a few years, or do you believe that most people will stick to the earlier standard in practice and C++0x will be somewhat of a bastard stepchild, kind of like C99?

• Does a persons' first programming language affect their programming style and if so, how? [closed]

  - by Scott Walsh

  I was speaking to an experienced lecturer recently who told me he could usually tell which programming language a student had learnt to program in by looking at their coding style (more specifically, when programming in other languages to the one which they were most comfortable with). He said that there have been multiple times when he's witnessed students attempted to write C# in Prolog. So I began to wonder, what specific traits do people gain from their first (or favourite) language which are carried over into their overall programming style, and more interestingly what good or bad habits do you think people would benefit from or should be wary of when learning specific language?

• Aside from performance concerns, is Java still chosen over Groovy/JRuby etc.?

  - by yar

  [This is an empirical question about the state-of-the-art: I am NOT asking if Java is cooler or less cool than the dynamic languages that work in the JVM.] Aside from cases where performance is a main decision factor, do companies/developers still willingly chose Java over Groovy, JRuby or JPython? Personal Note: The reason I am asking is that, while I do some subset of my professional work in Ruby (not JRuby, for now), in my personal projects I use Java. While I have written non-trivial apps in Groovy, I prefer Java, but I wonder if I should just get over it and do everything in Groovy. I like Java because I feel that static typing saves me time and aids refactoring. (No, I am not familiar with Scala.) However, I feel that this very empirical, on-topic programming question may inform my decision.

• Right programing language for developing application for Mac

  - by drasto

  I'm planing to buy Mac. I would like to be able to develop GUI aplication for Mac as well. Currently I develop in C# using VisualStudio as IDE. I also know Java and I'm familiar with NetBeans IDE. Application created in both of this languages can run on Mac (as can NetBeans IDE) but I was told that neither C# nor Java is recomended for MacOS X development. So what language is recomended for MacOS X development ? I guess there is some recomodation from Apple for the developers ? I would prefer Object-oriented easy-to-use programing language (nothing like C) with good IDE that supports GUI creating (GUI designer). Thank you for answers

• Whats the most useful programming language?

  - by Sebi

  I know this question was here a lot of times and can't be answered at all, but im not looking for a single name, but rather for an advice in my situation. I learned programming with Java and now I'm developing in Java for more or less 5 years (at the university) and I thinks my programming skills their are really ok/average. I have also small experience in C/C++ and C#. Now I have some spare time and I'd like to learn a new language or deepen the knowledge of Java/C/C++. But how to choose the right language to learn? I'd like to learn a language which will be usefull in the future concerning working in a software development business? I know there is no single answer, but I'm sure you could mention some languages that are more usefull than others.

• What to do with someone who can only use "the one true language"?

  - by Rob Wells

  G'day, How do you work with someone when they haven't been able to see that there is a range of other languages out there beyond "The One True Path"? I mean someone who hasn't grown up to realise that the modern software professional has a range of tools in his toolbox. Someone who has a well-equipped toolbox and then selects the best tool for the job at hand. The person who's knee jerk reaction is, for example, "We must do this is C++!" "Everything must be done in C++!" What's the best approach for these people? How do you open them up to the fact that "not everything is a nail." cheers,

• How to completely remove MySQL from a windows 7 machine

  - by Jazibobs

  I'm new to MySQL struggling to find a version and workbench which works stably on my 64 bit windows 7 machine. I've decided to attempt to completely remove MySQL from my machine and to restart the installation process from scratch. However, after uninstalling all software linked with MySQL using conventional control panel uninstalling means some MySQL windows services still remain on my machine. I can't see any obvious method to remove these and they have since been causing me difficulties when trying to install different versions of MySQL. Could anyone please advise?

• Can't add client machine to windows server 2008 domain controller

  - by Patrick J Collins

  A bit of background before I dive into the gritty details: I have a single server running Windows 2003 Server where I host my ASP.net website and SQL Server + Reports. I've been creating ordinary windows user accounts to authenticate my users, and I enabled integrated windows authentication with impersonation. I've set up a bunch of user groups which correspond to certain roles (admin, power user, normal user, etc) and I test membership to enable or disable certain features. Overall, I'm pretty happy with the solution, it was quick to setup and I don't have to worry about messing around storing passwords and whatnot. Well, what I'm trying to do now is set up a new environment with 3 servers (Web, SQL, Reports) and I'd like these three servers to share common user accounts. I understand that I could add these three machines to a domain, which means installing Active Directory on one of the machines. I am barking up the wrong tree here? Would you suggest an alternative configuration? Assuming that I stick with AD, I have a couple of questions regarding DNS. To be honest, I'd rather not fiddle around with the DNS settings because my ISP already has their own DNS server which works just fine. It would appear however that DNS and AD are intertwined. Firstly, if I am to create a new domain in called mycompany.net, do I actually need to be the registered owner of that domain name and ensure the DNS entry points to the IP address of the machine hosting AD? Secondly, for the two other machines that I am trying to add to the domain, do I need to fiddle with their DNS settings? I've tried setting the preferred DNS Server IP address to that of my newly installed AD, but no luck. At this point, I can't add the two other machines to the domain. Here are some diagnostics that I have run based on a few suggestions I read on forums (sorry they're in French, although I could translate if needed). I ran nltest, which seems to indicate that the client can discover the domain controller. When I run dcdiag, the call to DsGetDcName fails with error 1722, not really sure what that means. Any suggestions? Thanks!

• Having IIS remote management problem with my vista machine managing Server 2008 IIS 7.5

  - by Breadtruck

  I am trying to use IIS 7 Remote Management installed on Vista Ultimate SP1. Connection is to IIS 7.5 on Windows Server 2008 Webserver R2. Tried on both full & core install. When I connect up, the console wants to download and install new features. Microsoft.Web.Management.IisClient 7.5.0.0 Microsoft.Web.Management.AspnetClient 7.5.0.0 I check the boxes and click OK and it downloads them and asks if I want to install them, but after I click run it just quits. I tried just choosing one or the other, same thing. I ran IIS Remote tool as administrator. These features installed correctly on my XP machine. Any ideas? UPDATE : If I had any Rep I would offer like 500 rep to get this fixed!

• IIS Server on XP Machine with tweaked registry and services

  - by user420667

  I have been trying for some time now to setup a webapp on my XP machine at home. Prior to doing this, I had tweaked the registry settings, fiddled with disabling and enabling servies, without recording what I tweaked, which I imagining could be what's causing the problem. I don't want to "reboot" to factory settings, although I suppose that would be nice to know how to do as well. I am more interested in finding out what settings could have influenced the behavior, and who I could contact / what information I could send them that would aid in solving the problem. Thanks.

• restoring myisam mysql db on a different machine

  - by RainDoctor

  I have copied the web db directory(/var/lib/mysql/data/web/), when mysql is not running. I transferred this directory to another machine, where mysql is running. web db's stuff is myisam based. I am thinking about how to restore this on a different server. The strategy I have on my mind is the following. copy the data directory of web db to the new server. on new server, 'create database web', which creates a directory in /var/lib/mysql/data copy all files from the step to the new directory created in 2. bounce mysql My question: how to deal with information_schema for this new db?

• Dell Media Direct is rebooting my machine when it goes into sleep mode

  - by wsanville

  I've got a Dell Studio 1535 laptop, which shipped w/ Vista 32-bit. I've since formatted and installed Windows 7 64-bit. Everything has been fine for months, but recently, every time I leave my machine unattended and it goes to sleep, it wakes with the Dell Media Direct splash screen, and then goes to the "Windows was not shut down properly..." dialog that asks if you want to boot safe mode/start Windows normally/etc. The stupid button is also stuck on currently, but even when it is off, the problem still occurs. From the searching I've done, I've learned that the program is installed on its own partition, but I'm fairly certain I formatted everything. See screenie of my partitions: How can I stop the madness? Update: I've removed the 39 MB OEM Partition and it is still happening.

• Programmatically get the WLAN config of a machine and use netsh to setup new profile

  - by Maestro1024

  How can I programmatically get the wireless LAN configuration of a machine and use netsh to setup new profile? I am having trouble getting the netsh command to set the ssid of a new card. I installed the drivers and plugged it in. I see in ipconfig it says the "media is disconnected" (fair enough). I then send the following command netsh wlan connect name=profile1 ssid=myNetwork interface="Wireless Network Connection 2" problem is I get an error "There is no profile "profile1" assigned to the specified interface. What is a profile for a wireless card? What should I set it to? How can I get my SSID set and connected for the card?

• Security Essentials not installing and I suspect my machine is infected with malware

  - by Jim

  My mouse seems to be automatically right-clicking every few seconds, and sometimes constantly. My cursor will abruptly become an hourglass for a moment every once in a while, as well. It happens in spurts, as in it hasn't happened for about 10 minutes, but the preceding 20 before that it was happening constantly. I suspect that my machine is infected with malware of some sort, so I've tried installing Microsoft Security Essentials, but it presents the following error upon installation failure: My questions are: How can I solve the MSE installation issue and run a scan? Are there any indications that malware isn't actually my issue? Is MSE my best way to go about solving my issue, assuming that malware actually is the problem? Many thanks!

• How to manage configuration & automatic rollout of 20 virtual machines

  - by Lucas Meijer

  I have a TeamCity build server, with about 20 "build agents", both Windows and MacOS machines. Often, I need to install a newer version of XCode or VisualStudio or some other tool. Having to do this on all machines manually is boring and error prone. I'm trying to find out what is the best way to achieve the following: make it easy to change a system configuration, without having to do it on all machines manually. make it easy to add a new machine to the group. ensure the machines are as identical as possible The jobs these machines are executing is relatively heavy, fully consuming 8 cores, and be very heavy on IO. It's fine if the solution includes spending money.

• Using WinSCP with SSH server and 2 machine hops

  - by Mike

  I'm on a windows machine using putty to ssh into my schools server. From there I need to "slogin -XY machine1" and then "slogin -XY machine2" . Ideally, I'd like to use WinSCP to connect and transfer files. I know I can do this by using two copies of PuTTY , one to ssh into the server and create a proxy, and the second PuTTY to connect to the proxy and login to machine1 and create a second proxy. I can then use winSCP to connect to the proxy server and login to machine2... Is there a simpler way of doing this?

• Java 6.0 Virtual Machine re-caches application on every load

  - by David Neale

  I have a Java application which is loaded and cached by the JRE and for most users it only needs to cache once unless the application software has changed. However, I have one computer that caches the entire application every time they load it. It is not the version of the JRE, I have that running on other machines. It also works on this machine if logged in as a local admin, just not as a standard user. Does anybody have any ideas on what might be causing this?

I know I should use seperate machines but I'm on a budget this time of year. I also havn't kept up with hardware for quite a few years. Basically I know I want quad core, multiple monitor support (no gaming requirements). A lot of RAM, very quiet case and super fast HDD (SSD OR 10,000RPM)for compiling and latency. I will store libraries and other data on a USB drive. Sound card is not needed as I will be using an audio interface, all other music recording equipment is taken care of also. I could do with some decent monitor recomendations also. All suggestions welcome, thanks.

• md5sum repeatedly gives different checksum for same file on same machine

  - by Joel

  I have a very small and quite old hard drive disk, about 32G. On to this disk I have copied a largish tar file, about 5G. When I run md5sum to generate a checksum on this file I repeatedly get different results (on the same machine and the same file). This obviously should not happen. If I repeat the experiment with a much smaller file, as expected the checksum is the same each time. I can only assume that because the large file is spanning most of the disk, and it is an old drive, I am experiencing a lot of read errors on the hard drive - and it needs replacing? Could there be any other good reason for this? Something I can do to fix the problem other than buying a new disk? Update: sha1sum also produces inconsistent results.

• Will Dolphin emulator run (smoothly) on this machine?

  - by Mark

  Product Specs: Intel® NM10 Express chipset /w Intel® Atom® D525 (dual-core, 1.8 GHz) I think the most I can put in there for RAM is 4 GB. (They don't make 8 GB SODIMM do they?) The Dolphin site is pretty vague about requirements: Windows XP or higher, or Linux, or MacOSX Intel Fast CPU with SSE2. GPU with Pixel Shader 2.0 or greater. Some integrated graphics chips work but it depends on the model (and only with DirectX 9). I'm trying to make a light-weight quiet little machine for streaming video and playing eumulators, and I'm trying to figure out the minimum requirements I will need to do what I want. I know I'm not supposed to ask for product recommendations here, so if you could just advise the minimum requirements in terms of CPU, graphics card, and RAM, that'd be helpful.

• Routing to various node.js servers on same machine

  - by Dtang

  I'd like to set up multiple node.js servers on the same machine (but listening on different ports) for different projects (so I can pull any down to edit code without affecting the others). However I want to be able to access these web apps from a browser without typing in the port number, and instead map different urls to different ports: e.g. 45.23.12.01/app - 45.23.12.01:8001. I've considered using node-http-proxy for this, but it doesn't yet support SSL. My hunch is that nginx might be the most suitable. I've never set up nginx before - what configuration do I need to do? The examples of config files I've seen only deal with subdomains, which I don't have. Alternatively, is there a better (stable, hassle-free) way of hosting multiple apps under the same IP address?

• Password manager solution: Symbian based phone and a Linux machine (Windows is not important, but wo

  - by Kent

  Hi, I currently use KeePassX to manage my passwords on my Linux (Xubuntu) machine. It's nice to have all the passwords encrypted, but sometimes I'd like to be able to tell a password when I'm on the run. Therefore I'm looking for a solution which I can synchronize with my phone. I have a Nokia N82 which is a Symbian OS v9.2 based phone for the S60 3rd Edition platform with Feature Pack 1. I like an open source solution if it's possible. In case it isn't I wouldn't mind paying for a good solution. If Windows may be added to the synchronization mix it's nice, but it's absolutely not a primary requirement (I don't even have any computer running Windows).

• Correct password for ssh key rejected when ssh-d into machine

  - by user20342

  When I am logged into my machine directly, I can do all git operations, and when prompted for a password, the password is accepted. When I ssh into the same box and run git operations on the same repos, the password is rejected. Relevant section of .ssh/config looks like this: # Generic settings Host * ServerAliveInterval 600 ControlPath /tmp/ssh-%r@%h:%p ControlMaster auto KeepAlive yes IdentityFile ~/.ssh/id_rsa.pub Transaction looks like this when I login when I ssh into my box: {12-12-03 9:41}hbrown-wks2:~/workspace/spt/project@master??? hbrown% git pull Enter passphrase for key '/home/hbrown/.ssh/id_rsa.pub': Enter passphrase for key '/home/hbrown/.ssh/id_rsa.pub': Enter passphrase for key '/home/hbrown/.ssh/id_rsa.pub': Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. Using bash does not appear to make a difference (i.e. ssh-agent /bin/bash). This is a recent development, but I can't cite the change that caused it.
