• Why is iPhone mail much faster than Mail.app?

  - by Will Robertson

  It is noticeably faster to send and receive mail on my iPhone than on my MacBook, both through a Gmail IMAP account. (I'm still using Leopard, though.) I have a few rules set up in Mail, but it seems like the slowdown on the Mac is in the communication to Google's servers. Any explanations?

• 7zip: how to extract to std output?

  - by Jason S

  I have 7z 4.65 and am trying to extract a single file to standard output. The 7z command-line help says -so is the command-line parameter to extract to standard output, but when I try this: >>> 7z e -so dist\dlogpkg.jar META-INF/MANIFEST.MF 7-Zip 4.65 Copyright (c) 1999-2009 Igor Pavlov 2009-02-03 Error: I won't write data and program's messages to same terminal how can I fix this? There doesn't seem to be a command line param to suppress the normal 7z stdout messages. (edit: the equivalent operation in "unzip" would be unzip -p dist\dlogpkg.jar META-INF/MANIFEST.MF which works fine. But I'd like to use 7z for various reasons.)

• Sound card problem, no audio device detected

  - by Paul

  I bought a new sound card because my built in sound card did not function. When I open YouTube, Media Player or anything that can create a sound my computer will hang up and sometimes when I start my computer it will hang when the Windows XP sound will activate. Update: My computer has no audio. It says NO AUDIO DEVICE. I already installed Realtek AC97 and Realtek High Definition Audio Driver and I also pasted stream.dll to the Windows and system32 folders and I restarted my computer but it still says NO AUDIO DEVICE. Please help me. Thanks

• GNU Screen and Finch Not Playing Nicely

  - by Sean M

  I use finch for instant messaging, and for persistence, finch is one of the things that runs in my screen session. There are three main computers that I access my screen session from, and each works at a different screen resolution. Because of the different resolutions, when I switch computers, I use screen -rd to attach to my screen session. Using screen -x results in problems. When I attach to the session, though, finch experiences display problems. I have to wait up to several minutes for finch to become responsive - it doesn't redraw properly at all. Trying to switch between chats just writes ^n and ^p, or ^(1-9) for numbers. It fixes itself after some time. Using ctrl-l does not help. Switching back and forth between screen windows does not help. This is an annoying behavior that I don't experience with any other applications running in screen. Is this a bug in screen or finch, and if not, what can I change about my configuration to correct it ? (would appreciate it if "finch" could be used as a tag for this instead of or in addition to "pidgin")

• AnyCPU/x86/x64 for C# application and it's C++/CLI dependency

  - by Soonts

  I'm Windows developer, I'm using Microsoft visual studio 2008 SP1. My developer machine is 64 bit. The software I'm currently working on is managed .exe written in C#. Unfortunately, I was unable to solve the whole problem solely in C#. That's why I also developed a small managed DLL in C++/CLI. Both projects are in the same solution. My C# .exe build target is "Any CPU". When my C++ DLL build target is "x86", the DLL is not loaded. As far as I understood when I googled, the reason is C++/CLI language, unlike other .NET languages, compiles to the native code, not managed code. I switched the C++ DLL build target to x64, and everything works now. However, AFAIK everything will stop working as soon as my client will install my product on a 32-bit OS. I have to support Windows Vista and 7, both 32 and 64 bit versions of each of them. I don't want to fall back to 32 bits. That 250 lines of C++ code in my DLL is only 2% of my codebase. And that DLL is only used in several places, so in the typical usage scenario it's not even loaded. My DLL implements two COM objects with ATL, so I can't use "/clr:safe" project setting. Is there way to configure the solution and the projects so that C# project builds "Any CPU" version, the C++ project builds both 32 bit and 64 bit versions, then in the runtime when the managed .EXE is starting up, it uses either 32-bit DLL or 64-bit DLL depending on the OS? Or maybe there's some better solution I'm not aware of? Thanks in advance!

• const correctness

  - by ra170

  I was going through: C++ FAQs about inheritance and decided to implement it (just to learn it) #include "Shape.h" void Shape::print() const { float a = this->area(); // area() is pure virtual ... } now, everything (well, almost) works as described in item: faq:23.1 except that print() is const and so it can't access the "this" pointer, as soon as you take out const, it works. Now, C++ FAQs have been around for a while and are usually pretty good. Is this a mistake? Do they have typo or am I wrong? If I'm wrong, I would like to know how is it possible to access the "this" pointer in a const function.

• Flex wordwrap issue with multiple text instances

  - by Craig Myles

  Hi, I have a scenario where I want to dynamically add words of text to a container so that it forms a paragraph of text which is wrapped neatly according to the size of the parent container. Each text element will have differing formatting, and will have differing user interaction options. For example, imagine the text " has just spoken out about ". Each word will be added to the container one at a time, at run time. The username in this case would be bold, and if clicked on will trigger an event. Same with the news article. The rest of the text is just plain text which, when clicked on, would do nothing. Now, I'm using Flex 3 so I don't have access to the fancy new text formatting tools. I've implemented a solution where the words are plotted onto a canvas, but this means that the words are wrapped at a particular y position (an arbitrary value I've chosen). When the container is resized, the words still wrap at that position which leaves lots of space. I thought about adding each text element to an Array Collection and using this as a datasource for a Tile List, but Tile Lists don't support variable column widths (in my limited knowledge) so each word would use the same amount of space which isn't ideal. Does anyone know how I can plot words onto a container so that I can retain formatting, events and word wrapping at paragraph level, even if the container is resized?

• Core-Plot crash only in Release Configuration

  - by denbec

  Hey everyone, I really don't know a solution or even an idea to get around the following failure. It only happens in Release Configuration on the Device - Simulator and Debug Configuration work fine. It also only appears on the second launch. So if I have the phone connected to my mac, build the application and run it, everything works fine. If I then close the app and restart, it crashes. After long search, it seems that the error comes from the following line: x.majorIntervalLength = CPDecimalFromFloat(2.0f); The code before: CPLayerHostingView *chartView = [[CPLayerHostingView alloc] initWithFrame:CGRectMake(0, 0, 320, 160)]; [self addSubview:chartView]; // create an CPXYGraph and host it inside the view CPTheme *theme = [CPTheme themeNamed:kCPPlainWhiteTheme]; CPXYGraph *graph = (CPXYGraph *)[theme newGraph]; chartView.hostedLayer = graph; graph.paddingLeft = 20.0; graph.paddingTop = 10.0; graph.paddingRight = 10.0; graph.paddingBottom = 20.0; CPXYPlotSpace *plotSpace = (CPXYPlotSpace *)graph.defaultPlotSpace; plotSpace.xRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(0) length:CPDecimalFromFloat(100)]; plotSpace.yRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(0) length:CPDecimalFromFloat(10)]; CPXYAxisSet *axisSet = (CPXYAxisSet *)graph.axisSet; CPXYAxis *x = axisSet.xAxis; x.majorIntervalLength = CPDecimalFromFloat(2.0f); If I comment the last line, everything works fine (off course the interval length is not correct). I would appreciate any help! Thanks in advance!

• If you could take one computer science course now, what would it be?

  - by HenryR

  If you had the opportunity to take one computer science course now, and as a result significantly increase your knowledge in a subject area, what would it be? Undergraduate or graduate level. Compilers? Distributed algorithms? Concurrency theory? Advanced operating systems? Let me know why. (Note that I appreciate this isn't a far fetched scenario - but time and inertia might be preventing people from taking the course or reading the book or whatever)

  This Code triggers selection change event twice. how can I prevent it ? Currently i m using a flag or focused property to prevent this. But what is the actual way ? I am using it on winfoms EDIT My Mistake in writing Question, here is the correct code that i wanted to ask private void frmGuestInfo_Load(object sender, EventArgs e) { this.dgvGuestInfo.SelectionChanged -= new System.EventHandler(this.dgvGuestInfo_SelectionChanged); dgvGuestInfo.DataSource=dsFillControls.Tables["tblName"]; this.dgvGuestInfo.SelectionChanged += new System.EventHandler(this.dgvGuestInfo_SelectionChanged); } private void dgvGuestInfo_SelectionChanged(object sender, EventArgs e) { //this function is raised twice, i was expecting that this will not be raised }

• Get content of XML node using c#

  - by Adam S

  Hi all, simple question but I've been dinking around with it for an hour and it's really starting to frustrate me. I have XML that looks like this: <TimelineInfo> <PreTrialEd>Not Started</PreTrialEd> <Ambassador>Problem</Ambassador> <PsychEval>Completed</PsychEval> </TimelineInfo> And all I want to do is use C# to get the string stored between <Ambassador> and </Ambassador>. So far I have: XmlDocument doc = new XmlDocument(); doc.Load("C:\\test.xml"); XmlNode x = doc.SelectSingleNode("/TimelineInfo/Ambassador"); which selects the note just fine, now how in the world do I get the content in there?

• [Scala] Applying overloaded, typed methods on a collection

  - by stephanos

  I'm quite new to Scala and struggling with the following: I have database objects (type of BaseDoc) and value objects (type of BaseVO). Now there are multiple convert methods (all called 'convert') that take an instance of an object and convert it to the other type accordingly - like this: def convert(doc: ClickDoc): ClickVO = ... def convert(doc: PointDoc): PointVO = ... def convert(doc: WindowDoc): WindowVO = ... Now I sometimes need to convert a list of objects. How would I do this - I tried: def convert[D <: BaseDoc, V <: BaseVO](docs: List[D]):List[V] = docs match { case List() => List() case xs => xs.map(doc => convert(doc)) } Which results in 'overloaded method value convert with alternatives ...'. I tried to add manifest information to it, but couldn't make it work. I couldn't even create one method for each because it'd say that they have the same parameter type after type erasure (List). Ideas welcome!

• NHibernate handling mutliple resultsets from a sp call

  - by Michael Baldry

  I'm using a stored procedure to handle search on my site, it includes full text searching, relevance and paging. I also wanted it to return the total number of results that would have been returned, had paging not being there. So I've now got my SP returning 2 select statements, the search and just SELECT @totalResults. Is there any way I can get NHibernate to handle this? I'm currently accessing the ISession's connection, creating a command and executing the SP myself, and mapping the results. This isn't ideal, so I'm hoping I can get NH to handle this for me. Or if anyone has any other better ways of creating complicated searches etc with NH, I'd really like to hear it.

• How to use Linq with Castle ActiveRecord

  - by Ronnie Overby

  I am playing around with Castle ActiveRecord and noticed that the download included the file, Castle.ActiveRecord.Linq.dll. I haven't found any documentation for using Linq with ActiveRecord, only some old blog posts. What is the usage pattern? Is Castle.ActiveRecord.Linq ready for production use? I'm using reflector, pending an answer.

• JavaCC: How can one exclude a string from a token? (A.k.a. understanding token ambiguity.)

  - by java.is.for.desktop

  Hello, everyone! I had already many problems with understanding, how ambiguous tokens can be handled elegantly (or somehow at all) in JavaCC. Let's take this example: I want to parse XML processing instruction. The format is: "<?" <target> <data> "?>": target is an XML name, data can be anything except ?>, because it's the closing tag. So, lets define this in JavaCC: (I use lexical states, in this case DEFAULT and PROC_INST) TOKEN : <#NAME : (very-long-definition-from-xml-1.1-goes-here) > TOKEN : <WSS : (" " | "\t")+ > // WSS = whitespaces <DEFAULT> TOKEN : {<PI_START : "<?" > : PROC_INST} <PROC_INST> TOKEN : {<PI_TARGET : <NAME> >} <PROC_INST> TOKEN : {<PI_DATA : ~[] >} // accept everything <PROC_INST> TOKEN : {<PI_END : "?>" > : DEFAULT} Now the part which recognizes processing instructions: void PROC_INSTR() : {} { ( <PI_START> (t=<PI_TARGET>){System.out.println("target: " + t.image);} <WSS> (t=<PI_DATA>){System.out.println("data: " + t.image);} <PI_END> ) {} } Let's test it with <?mytarget here-goes-some-data?>: The target is recognized: "target: mytarget". But now I get my favorite JavaCC parsing error: !! procinstparser.ParseException: Encountered "" at line 1, column 15. !! Was expecting one of: !! Encountered nothing? Was expecting nothing? Or what? Thank you, JavaCC! I know, that I could use the MORE keyword of JavaCC, but this would give me the whole processing instruction as one token, so I'd had to parse/tokenize it further by myself. Why should I do that? Am I writing a parser that does not parse? The problem is (i guess): hence <PI_DATA> recognizes "everything", my definition is wrong. I should tell JavaCC to recognize "everything except ?>" as processing instruction data. But how can it be done? NOTE: I can only exclude single characters using ~["a"|"b"|"c"], I can't exclude strings such as ~["abc"] or ~["?>"]. Another great anti-feature of JavaCC. Thank you.

• Is there something similar to 'rake routes' in django?

  - by The MYYN

  In rails, on can show the active routes with rake (http://guides.rubyonrails.org/routing.html): $ rake routes users GET /users {:controller=>"users", :action=>"index"} formatted_users GET /users.:format {:controller=>"users", :action=>"index"} POST /users {:controller=>"users", :action=>"create"} POST /users.:format {:controller=>"users", :action=>"create"} Is there a similar tool/command for django showing the e.g. the URL pattern, the name of the pattern (if any) and the associated function in the views?

• Is there a 128 or 256 bit double class in .net?

  - by AKRamkumar

  I have an application that I want to be able to use large numbers and very precise numbers. For this, I needed a precision interpretation and IntX only works for integers. Is there a class in .net framework or even third party(preferably free) that would do this? Is there another way to do this?

• Clarification required re use of .NET Assemblies in GAC - Use to use Globally?

  - by Cognize

  Hi, I've done much reading and experimentation today regarding sigining of assemblies, and their installation into the GAC via various methods (mscorcfg.msc / drag and drop). What I thought, was that once a file was in the GAC, you did not need to make references from projects in Visual studio. I know that you CAN make references via the usual Add Reference, Browse etc, but I thought it was automatic. Testing proves this not to be the case. I came across a forum post looking to achieve the same outcome that suggested adding to the machine.config file under system.web as below. This did not work, it in fact broke visual studio until I removed it. <assemblies> <add assembly="Blah.Framework.Logging, Version=1.0.3806.25580, Culture=neutral, PublicKeyToken=0beed4b631ebc3cd" /> </assemblies> What I want to know, is am I right in my assumed use of assemblies in the GAC, and is there a way of making them globally available?

• Windows command line built-in compression/decompression tool?

  - by Will Marcouiller

  I need to write a batch file to unzip files to their current folder from a given root folder. Folder 0 |----- Folder 1 | |----- File1.zip | |----- File2.zip | |----- File3.zip | |----- Folder 2 | |----- File4.zip | |----- Folder 3 |----- File5.zip |----- FileN.zip So, I wish that my batch file is launched like so: ocd.bat /d="Folder 0" Then, make it iterate from within the batch file through all of the subfolders to unzip the files exactly where the .zip files are located. So here's my question: Does the Windows (from XP at least) have a command line for its embedded zip tool? Otherwise, shall I stick to another third-party util?

• Cisco ASA and SixXS IPv6 tunnel endpoint?

  - by Martijn Heemels

  I recently installed a Cisco ASA 5505 firewall on the edge of our LAN. The setup is simple: Internet <-- ASA <-- LAN I would like provide the hosts in the LAN with IPv6 connectivity by setting up a 6in4 tunnel to SixXS. It would be nice to have the ASA as tunnel endpoint so it can firewall both IPv4 and IPv6 traffic. Unfortunately the ASA apparently can't create a tunnel itself, and can't port-forward protocol 41 traffic, so I believe I would have to do one of the following instead: Set up a host with it's own IP outside the firewall, and have that function as tunnel-endpoint. The ASA can then firewall and route the v6 subnet to the LAN. Set up a host inside the firewall that functions as endpoint, separated via vlan or whatever, and loop the traffic back into the ASA where it can be firewalled and routed. This seems contrived, but would allow me to use a VM instead of a physical machine as endpoint. Any other way? What would you suggest is the optimal way to set this up? P.S. I do have a spare public IP address available if needed, and can spin up another VM in our VMware infrastructure.

• Approach for monitoring internet backbone traffic volume

  - by Greg Harman

  I'm interested in getting a picture of relative volume across different internet backbones. In particular, I'd like to see how traffic volume over a given route differs over the course of a day or from one day to the next. InternetTrafficReport.com is the closest approximation to this that I've found online, and their approach is to test ping times to a number of key routers from several geographically-dispersed servers. This sounds like one straightforward way to measure, but I don't have several geographically-dispersed servers. Is there a different approach for sampling this type of information from a single server?
