• Samba 3.3 or later on Slackware 12 - how do I make this happen?

  - by caroulia

  I'm trying to upgrade the Samba server on a Slackware 12 box to serve as PDC for Windows 7 32bit machines (it now has a 3.0.3 and does the job for Win XP machines, but 7 refuses to join the domain - I'm posting this after having tried a few dozen hacks on the windows registry). I'm a newbie on Slackware (I usually dwell in Ubuntu) so I may be going about this the wrong way but this is what I've done so far: The Samba wiki has a couple of hacks for the registry and also seems to suggest a version later than 3.3 (though not in so many words) http://wiki.samba.org/index.php/Windows7 Having scoured the net for later Samba binaries for Slackware 12 and gotten precisely nowhere, I decided that maybe I could compile the blessed thing. But I keep on getting compiler errors. I'm using this SlackBuild script http://ftp.twaren.net/Linux/slackware/slackware-current/source/n/samba/samba.SlackBuild Is there a better way to make this happen? (without upgrading the base system? it has so many finely tuned things running that I don't want to mess with the rest of the setup).

• ifconfig return "unknown interface: no such device"

  - by xolstice

  I'm trying to install a Linux driver for my wireless network card (D-Link DWL-G510) on my Red Hat Linux 7.1 machine with a 2.4.37.9 kernel. I downloaded the serial monkey driver from the sourceforge site and was able to successfully compile the rt73 module and load it into the kernel. The problem now is that everytime I issue the command ifconfig wlan0 up it keeps returning with the following error message: wlan0: unknown interface: No such device. I'm at a loss as to what to do here. I specifed wlan0 as the alias for the rt73 module in the modules.conf and also tried to load the driver with the command modprobe rt73 ifname=wlan0 (this specifies the interface name according to the instructions packaged in the driver), but the error message still keeps coming up. Is there something else I need to do in Linux to configure the wlan0 part or is the module not recognizing the wireless network card? It would be quite strange if it is the later since all information from the Internet is indicating this is the linux driver I should be using for mentioned wireless card.

• Linking LLVM JIT Code to Static LLVM Libraries?

  - by inflector

  I'm in the process of implementing a cross-platform (Mac OS X, Windows, and Linux) application which will do lots of CPU intensive analysis of financial data. The bulk of the analysis engine will be written in C++ for speed reasons, with a user-accessible scripting engine interfacing with the C++ testing engine. I want to write several scripting front-ends over time to emulate other popular software with existing large user bases. The first front will be a VisualBasic-like scripting language. I'm thinking that LLVM would be perfect for my needs. Performance is very important because of the sheer amount of data; it can take hours or days to run a single run of tests to get an answer. I believe that using LLVM will also allow me to use a single back-end solution while I implement different front-ends for different flavors of the scripting language over time. The testing engine itself will be separated from the interface and testing will even take place in a separate process with progress and results being reported to the testing management interface. Tests will consist of scripting code integrated with the testing engine code. In a previous implementation of a similar commercial testing system I wrote, I built a fast interpreter which easily interfaced with the testing library because it was written in C++ and linked directly to the testing engine library. Callbacks from scripting code to testing library objects involved translating between the formats with significant overhead. I'm imagining that with LLVM, I could implement the callbacks into C++ directly so that I could make the scripting code work almost as if it had been written in C++. Likewise, if all the code was compiled to LLVM byte-code format, it seems like the LLVM optimizers could optimize across the boundaries between the scripting language and the testing engine code that was written in C++. I don't want to have to compile the testing engine every time. Ideally, I'd like to JIT compile only the scripting code. For small tests, I'd skip some optimization passes, while for large tests, I'd perform full optimizations during the link. So is this possible? Can I precompile the testing engine to a .o object file or .a library file and then link in the scripting code using the JIT? Finally, ideally, I'd like to have the scripting code implement specific methods as subclasses for a specific C++ class. So the C++ testing engine would only see C++ objects while the JIT setup code compiled scripting code that implemented some of the methods for the objects. It seems that if I used the right name mangling algorithm it would be relatively easy to set up the LLVM generation for the scripting language to look like a C++ method call which could then be linked into the testing engine. Thus the linking stage would go in two directions, calls from the scripting language into the testing engine objects to retrieve pricing information and test state information and calls from the testing engine of methods of some particular C++ objects where the code was supplied not from C++ but from the scripting language. In summary: 1) Can I link in precompiled (either .bc, .o, or .a) files as part of the JIT compilation, code-generation process? 2) Can I link in code using that the process in 1) above in such a way that I am able to create code that acts as if it was all written in C++?

• PHP: Can pcntl_alarm() and socket_select() peacefully exist in the same thread?

  - by DWilliams

  I have a PHP CLI script mostly written that functions as a chat server for chat clients to connect to (don't ask me why I'm doing it in PHP, thats another story haha). My script utilizes the socket_select() function to hang execution until something happens on a socket, at which point it wakes up, processes the event, and waits until the next event. Now, there are some routine tasks that I need performed every 30 seconds or so (check of tempbanned users should be unbanned, save user databases, other assorted things). From what I can tell, PHP doesn't have very great multi-threading support at all. My first thought was to compare a timestamp every time the socket generates an event and gets the program flowing again, but this is very inconsistent since the server could very well sit idle for hours and not have any of my cleanup routines executed. I came across the PHP pcntl extensions, and it lets me use assign a time interval for SIGALRM to get sent and a function get executed every time it's sent. This seems like the ideal solution to my problem, however pcntl_alarm() and socket_select() clash with each other pretty bad. Every time SIGALRM is triggered, all sorts of crazy things happen to my socket control code. My program is fairly lengthy so I can't post it all here, but it shouldn't matter since I don't believe I'm doing anything wrong code-wise. My question is: Is there any way for a SIGALRM to be handled in the same thread as a waiting socket_select()? If so, how? If not, what are my alternatives here? Here's some output from my program. My alarm function simply outputs "Tick!" whenever it's called to make it easy to tell when stuff is happening. This is the output (including errors) after allowing it to tick 4 times (there were no actual attempts at connecting to the server despite what it says): [05-28-10 @ 20:01:05] Chat server started on 192.168.1.28 port 4050 [05-28-10 @ 20:01:05] Loaded 2 users from file PHP Notice: Undefined offset: 0 in /home/danny/projects/PHPChatServ/ChatServ.php on line 112 PHP Warning: socket_select(): unable to select [4]: Interrupted system call in /home/danny/projects/PHPChatServ/ChatServ.php on line 116 [05-28-10 @ 20:01:15] Tick!

• emacs error: "Symbol's value as variable is void: hostname"

  - by Florian Pilz

  After I installed emacs this error occurs every time on startup. It prevents me from installing plugins, e.g. auctex via aptitude. I already tried to install a plugin by hand (rails for ruby), but doesn't work. The error doesn't contain the message "hostname", but the hostname of my PC is displayed ("bloodredangel-ubuntu"). I changed my hostname to "bloodredangel", but the error message stays the same. While I changed my hostname I saw that in /etc/hostname were two entries: 127.0.0.1 bloodredangel-ubuntu I already asked this question in an ubuntu forum but they couldn't help. They recognised an misconfigured /etc/hosts file, which I corrected, but from time to time these incorrect configurations get attached by something. I didn't add them by hand, maybe it has something to do with the issue. The misconfigurations looked like this: 127.0.0.1 127.0.0.1 bloodredangel-ubuntu localhost.localdomain localhost 127.0.0.1 127.0.0.1:8080 bloodredangel-ubuntu localhost.localdomain localhost I didn't found a solution on the internet, so I hope I will find help here finally.

• PHP shared extensions on Linux

  - by F21

  I am running Ubuntu Server 12.04 and prefer to compile PHP myself as opposed to installing it using apt-get. PHP is running as PHP-FPM. When compiling extensions, I can set it to be compiled as a shared extension using something like --with-bcmath=shared and so on. Are there any benefits to compiling the extensions as shared? I also noticed that the extensions are compiled into a pretty convoluted folder. On my system (my php prefix is /usr/local/php-5.4.9) the extensions end up in /usr/local/php-5.4.9/lib/php/extensions/no-debug-non-zts-20100525. Is there a global way to set a folder so that all shared extensions will be compiled in there? I understand that I can do something like --with-foobar=shared,/usr/local/foobar/ but having to set the extension folder for each shared extension is inefficient and error-prone.

• Windows 8 auto-hibernate from sleep not working on Retina MacBook Pro

  - by frenchglen

  I have a similar question to this one. Only my context is the 15" Retina MacBook Pro - and Windows 8. I have just the original Mac OS X Mountain Lion on there, then Windows 8 via Bootcamp. no rEFIt installed. (I just press ALT every time I restart windows, actually as a security measure to stop tech-unsavvy thugs, who, if the laptop is stolen, think it's only a mac and don't discover my Windows as quickly as they would've, and by that time I remotely activate various anti-theft mac apps and nab them that way). SO: like the related question asks, why isn't it behaving like it should? The Windows 7 FAQ states: Will sleep eventually drain my laptop battery? If your laptop battery charge gets critically low while the computer is asleep, Windows automatically puts the laptop into hibernation mode. But this is just not happening - on my rMBP Windows 8. It seems EVERY time I set the laptop to sleep (when it reaches 10%), then arriving home and plugging it in and hoping to simply resume my work, it does NOT save the session to disk and I lose ALL my work. Who's fault is it? Win 8's (a bug, grr)? Or Apple's EFI system (maybe fixable via editing EFI options/do I have to install refit to make it work perhaps?) Or maybe changing windows power options can somehow fix the problem? Thanks for your help.

• Groovy concurrency: A better way to aggregate results semantically?

  - by Stefan Kendall

  I need to call a number of methods in parallel and wait for results. Each relies on different resources, so they may return at different times. I need to wait until I receive all results or time out after a certain amount of time. I could just spawn threads with a reference to a shared object via a method call, but is there a better, more groovy way to do this?

• How to run MS C++ 6.0 on Windows 7

  - by hotei

  I have MS Windows C++ version 6.0 on XP. I'd like to move it to a Windows 7 platform but when I try to install it there I get some garbage about it not being compatible, proceed at your own risk etc. When I proceed, it (not surprisingly) doesn't work. Is there a way to convince these Microsoft tools to play nice with each other? I have Win7 home edition, but I would be willing to upgrade to Win7 Pro IF I knew it would work under the "XP emulation" mode. Failing both those options, what is the least expensive "upgrade" path for C++? I don't need a bunch of other junk, just the C++ compiler. The goal is to retire my XP system since currently the only reason I keep it is to compile C++ programs that eventually are run under Win7. Thanks, Hotei

• Recursive String Function (Java)

  - by Jake Brooks

  Hi, I am trying to design a function that essentially does as follows: String s = "BLAH"; store the following to an array: blah lah bah blh bla bl ba bh ah al So basically what I did there was subtract each letter from it one at a time. Then subtract a combination of two letters at a time, until there's 2 characters remaining. Store each of these generations in an array. Hopefully this makes sense, Jake

• Is there a way to copy the file paths of ALL active windows' opened files?

  - by frenchglen

  The context of this question, is here. I actually know the answer to my question is yes - like I say in my context, this program can do it (somehow). So the really question is, how can I do it. What code do I put in a simple batch file? (or do I have to compile a tiny c++ exe? and run that exe in the batch file?) Might this code be a solution? (.....EnumDesktopWindows?) To clarify, I know that there's e.g. NirSoft OpenedFilesView which shows allll the technically-opened files in Windows, but it's just the 'visible' user-opened ones that I'm after (whatever you can see in Task Manager's Applications tab). Thanks.

• Is there a way to reuse an XmlReader?

  - by uriDium

  I have a process that uses an XmlReader. I have already done a lot to squeeze maximum performance out of it. So far we have had huge gains from using the Reader as opposed to XmlDoc or DataSet.GetXml(). We expect to get XML many times a second and I would like to avoid the overhead of recreating the reader every time. I have already cached the XmlReaderSettings but is there anyway to reuse the XmlReader or do I need to recreate it every time?

• How much network latency is "typical" for east - west coast USA?

  - by Jeff Atwood

  At the moment we're trying to decide whether to move our datacenter from the west coast to the east coast. However, I am seeing some disturbing latency numbers from my west coast location to the east coast. Here's a sample result, retrieving a small .png logo file in Google Chrome and using the dev tools to see how long the request takes: West coast to east coast: 215 ms latency, 46 ms transfer time, 261 ms total West coast to west coast: 114 ms latency, 41 ms transfer time, 155 ms total It makes sense that Corvallis, OR is geographically closer to my location in Berkeley, CA so I expect the connection to be a bit faster.. but I'm seeing an increase in latency of +100ms when I perform the same test to the NYC server. That seems .. excessive to me. Particularly since the time spent transferring the actual data only increased 10%, yet the latency increased 100%! That feels... wrong... to me. I found a few links here that were helpful (through Google no less!) ... Does routing distance affect performance significantly? How does geography affect network latency? Latency in Internet connections from Europe to USA ... but nothing authoritative. So, is this normal? It doesn't feel normal. What is the "typical" latency I should expect when moving network packets from the east coast <--> west coast of the USA?

• Default permissions for courier imap folders

  - by JoeCoder

  I'm using courier imap. When a mail client creates a new folder, it's created on the filesystem with 640 permission. I need it to be writable by the group, or 660. I currently have /etc/courier/imapd IMAP_UMASK=007, but that's not enough. I'm not sure what else to try. Any ideas? I'm using ubuntu server 12.04. EDIT: I added a 50pt bounty to this. For an acceptable answer, I need a way to make it work from a package in a standard repo. If I download source and compile it myself, it won't be automatically kept up to date with security fixes. If I don't find a better answer, I'll add code to the admin script to call another sudo approved script to chmod -R the whole directory before every change. But this is kind of hack-ish.

From the little JSON knowledge I have, I thought this format for the response from server { "post": { "username": "someusername", "message": "this is a sweet message", "image": "http://localhost/someimage.jpg", "time": "present time" }, } How much knowledge of JSON should I have to accomplish this purpose? Also it would be great if someone could provide me links of some tutorials for sending and parsing JSON Objects.

• multicast tcpdump and subscriptions

  - by Karoly Horvath

  From the multicast howto: IP_ADD_MEMBERSHIP. Recall that you need to tell the kernel which multicast groups you are interested in. If no process is interested in a group, packets destined to it that arrive to the host are discarded. If you don't do that, you won't see those packets with tcpdump. Is it possible to subscribe to all multicast traffic so I can do a tcpdump for all existing traffic? I would think IGMP doesn't allow this, so probably not.. but maybe you can configure a switch to still send all multicast traffic. Is that possible? Is it possible to do subscription (for a specific IP) with a command line tool? (note: I know how to do this in C.. but would prefer to use an existing tool and not compile a separate program for this)

• Best CPUs for speeding up compiling times of C++ w/ DistGCC

  - by Jay

  I'm putting together a distributed build farm with DistGCC to speed up our teams compile times and just looking for thoughts on which processors to use in the hosts. Are we going to get a noticeable decrease in time using 8 cores vs. 4-hyperthreaded cores? Big difference in time between i7 and Xeon? etc, etc. Just need advice from people who've put together kick-a build clusters. We've got a majority of the normal things to speed up builds in place (pre-compiled headers, ccache, local gigabit connections between them, tons of ram, etc) so please just give advice on the best processor to use. And money is a factor, but anythings doable if the performance increase is noticeable. Thanks. Jay EDIT: Although any advice IS welcome, please refrain from "Do this first" posts as we're not planning on skimping on things like SSD, maxed out RAM, etc. My personal system is a iMac Quad-core i5 with 8GB of RAM. When I build our project locally, my processor floats around 99-100% a majority of the time, which makes me assume it is a bottleneck, even if you made everything else faster. My ram on the other hand doesn't even get close to maxing out. It's also worth noting that I did research this, however every discussion I could find was primarily for gaming machines, which is obviously a different beast in usage.
