• Using the vim split command from the command line to get 4 quater splits

  - by sixtyfootersdude

  I want to open four vim files on the command line: vim file1 file2 file3 But I would like each file to be opened in a separate split: vim -c "split file1" -c "split file2" -c "split file3" file4 (The above splits the screen horizontally 4 times) Ideally what I would like to do is split the screen into 4 squares like: |-------|-------| | | | | | | |-------|-------| | | | | | | |-------|-------| I know how to do this once vim is open but I am unable to do this from the command line (using vs). Any ideas? Everything I try ends up looking like this (or a different variation): |-------|-------| | | | |-------| | | | | |-------| | | | | | | | |-------|-------|

• How to use Application.OnTime to call a macro at a set time everyday, without having to close workbook

  - by Shayne K

  I have written a macro that uses Application.OnTime that works if I manually execute the macro. I'm trying to automate this process so I don't have to write Application.OnTime in "This Workbook" or (Private Sub Workbook_Open() Most of you do this because you can have windows scheduler open the workbook at a certain time which starts the macros on open. I CANNOT USE SCHEDULER. Because I am not able to use windows scheduler I will keep the workbook open and the timer should refresh my data then Call "my Macro" at a certain time everyday. Where do I place this code, and how do I set an auto timer?

• Send Email on GMail SMTP under medium trust

  - by Midhat

  Hi I need to send an email from my app, which will be running under medium trust. My current email sending code that works fine under full trust throws SecurityException under medium trust [SecurityException: Request for the permission of type 'System.Net.Mail.SmtpPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.] Examining my machine.config and allied files reveal that my SMTP access is restricted to Connect. <SecurityClass Name="SmtpPermission" Description="System.Net.Mail.SmtpPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> and <IPermission class="SmtpPermission" version="1" Access="Connect"/> According to MSDN, Connect allows request on port 25 only. But Gmail servers work on port 587. Any workarounds? suggestions?

• Jquery click behaviour

  - by VP

  I'm developing a menu. This menu, will change the background image when you click on a link, as almost all menus does. if i click in one link from the menu, this link backgroun will change the color. My jquery script is: $(function() { $('#menu ul li').click(function() { $('#menu ul li').removeClass("current_page_item"); $(this).addClass("current_page_item"); //return false; }); }); today, with the "return false" commented, when i click on the link under "#menu ul li" it changes the background open the new page and the background is reseted. For sure, if i uncomment the return false, the background works fine but then i cannot open any link. So its looks like after that i open a new page, it reset the classes. How can i make it persistent?

• GDB skips over my code!

  - by sheepsimulator

  So, I've defined a class like DataLoggingSystemStateReceiver { DataLoggingSystemStateReceiver() { // stuff } // ... other functions here }; In main, I instantiate DataLoggingSystemStateReceiver like so: int main() { // ... run stuff Sensor sensor(port, timer); DataLoggingSystemStateReceiver dlss(); Log::notice("started"); return 0; } However, when I step through this code in gdb, it runs: Sensor sensor(port, timer); skips DataLoggingSystemStateReceiver dlss(); and continues with Log::notice("started"); What gives? EDIT: By changing DataLoggingSystemStateReceiver dlss(); to DataLoggingSystemStateReceiver dlss; in main(), the line executes. Can someone explain why?

• Why would a UIDatePicker with no functionality, added to my app via IB, cause my app to crash?

  - by BeachRunnerJoe

  I just added a UIDatePicker to my iPad app using IB, linked it to its outlet in the code, saved it in IB, added the UIPickerViewDelegate to my UIViewController in the code, as well as added the UIDatePicker outlet in code. When I build and run, the app launches, but will crash intermittently when I attempt to open the popover view that contains the datepicker. I say intermittently because the popover view will occasionally open successfully, but never more than once (it always crashes the second time you open the popover, if it doesn't crash the first time). Also, in the console, I get the following messsage objc[594]: FREED(id): message lastClickRow sent to freed object=0x6015a70 Why is this happening and how can I fix it? What does that console message indicate? It may be worth mentioning that the popover view also contains a table view along with the datepicker control. Thanks so much in advance for your help!

• Django: tinyMCE and cross site javascript

  - by pistacchio

  Hi, follow this question, I was able to set some textareas in my admin page as richtext inputs. The most voted answer suggests to follow an example and is what i did. Also, it talks about a problem concerning "blank pages". I'm having the same problem and I'm not able to solve it. I have my media files served by a different server, so MEDIA_URL points to a different host with a different port. To simulate this in my dev environment, I also serve media files from a different port. Debugging the failing javascript, Chrome yelds: Unsafe JavaScript attempt to access frame with URL http://localhost:8000/admin/blog/post/add/ from frame with URL http://localhost:88/s3mangerie/js/tiny_mce/themes/advanced/image.htm. Domains, protocols and ports must match. How to solve this problem? Thanks

  The latest MacRuby release notes (v0.6) state that the authors have managed to get this release working with the SQLite and Nokogiri gems.

• Ruby: writing a network redirector

  - by Shyam

  Hi, I would like to research protocols such as HTTP. As I am learning Ruby, I would like to write a program that works as a "gateway". I would be connecting to it's port on for example 8080 and the program should forward my request to the real host and send back the answers. The idea of my design is something like this: class EchoProxy def run # run a listening socket on port 8080 myinfiniteloop end def myinfiniteloop # continually run this loop unless the app is terminated puts traffic end end Some pointers in the right direction would be great! Thank you for your comments, answers and feedback!

• Cinema4D XML scene not rendering texture

  - by George Profenza

  I exported a basic Cinema4D scene as XML (File Export Cinema 4D XML) then opened up the xml in Cinema4D and it looses the reference to the texture applied. If I open up the original c4d file and render it I can see my texture applied. If I open up the exported xml file and render it the texture is missing. Any way to get around that ?

• What does transactions per seconds for a load balancer mean

  - by Anurag

  I was looking at the product matrix of webmux 592G(load balancer). It says maximum connections per sec = 2.8M Maximum number of transactions = 100,000 What does the above numbers mean. Does above means that load balancer can have 2.8M connections open but only 100K of them will be active per seconds. Also incase any one has used webmux 592G do you guys know in practice how many connections it can have open and what qps it can serve

• firefox: getting access to the list of tabs/windows to restore on startup

  - by robb

  Sometimes ffox fails to restore the previously open tabs/windows. This might be happening when some of the urls to be opened are no longer reachable (e.g. behind a vpn) or after the underlying OS (Windows) has been forcibly restarted (e.g. to complete an automated patch installation). Anyway, after restarting, can this list of urls be recovered somehow? Say for example, I was daft enough to have clicked on "start new session". Can I still get access to the old list of open urls? There is the browser history of course, but it contains a lot of stuff - the urls that were open when ffox last exited are not obvious. It would be neat if they were marked in some way - tagged for example. .robb

• Question regarding the ExtJS License

  - by stephemurdoch

  Let's say I create a CMS that uses ExtJS. I want to avoid the license fee, so I open-source the CMS on github. Now let's imagine that I make your friend Dave a website that uses my CMS. I spend three hundred hours designing a logo and designing the layout. Can I charge a fee for this, and would I be obliged to open-source Dave's website too or is it enough to just open-source the CMS? I find this LPGL license a little confusing. Say hi to Dave for me.

• Click GEvent.addListener with jquery

  - by Jason

  Created a google map with GMap2 and put pinpoints on there that open up a balloon with the address when the pinpoint is clicked. I would like users to be able to click text on the page itself and use jquery to open up the corresponding balloon. However I can't figure out the ID to use to call a jquery click event. Basically I've got a store listing down the left side and when user clicks store name I want it to open up the corresponding balloon. GEvent.addListener(marker_500, "click", function () { map.openInfoWindowHtml(point, myHtml); } Any idea what element tied to this click event is? Tried $("#marker_500").click(); And that doesn't work. Also tried alerting $(this).attr('id'); inside the click function and that is undefined. thanks jason

• ODBC Connection Pooling

  - by beansy

  I have inherited a suite of .Net c# applications from a developer which talk to an Informix database on a unix server. Instead of using the usual practices for managing the database connections (disposable pattern / "open late / close early"), the code seems to open one ODBC connection when each app loads and doesn't close it. Connection pooling is turned via the ODBC administrator. Is there any way of seeing how many ODBC connections are open? What is the effect of turning off connection pooling? Am I right in thinking the .NET framework will use connection pooling anyway?

• Grouping with operands question

  - by Filip

  I have a table: mysql> desc kursy_bid; +-----------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-----------+-------------+------+-----+---------+-------+ | datetime | datetime | NO | PRI | NULL | | | currency | varchar(6) | NO | PRI | NULL | | | value | varchar(10) | YES | | NULL | | +-----------+-------------+------+-----+---------+-------+ 3 rows in set (0.01 sec) I would like to select some rows from a table, grouped by some time interval (can be one day) where I will have the first row and the last row of the group, the max(value) and min(value). I tried: select datetime, (select value order by datetime asc limit 1) open, (select value order by datetime desc limit 1) close, max(value), min(value) from kursy_bid_test where datetime > '2009-09-14 00:00:00' and currency = 'eurpln' group by month(datetime), day(datetime), hour(datetime); but the output is: | open | close | datetime | max(value) | min(value) | +--------+--------+---------------------+------------+------------+ | 1.4581 | 1.4581 | 2009-09-14 00:00:05 | 4.1712 | 1.4581 | | 1.4581 | 1.4581 | 2009-09-14 01:00:01 | 1.4581 | 1.4581 | As you see open and close is the same (but they shouldn't be). What should be the query to do what I want?

• Proxy calls across a DMZ

  - by John

  We need to determine a quick way for our web application deployed in a DMZ to communicate to our SQL server that lives in the protected network. Only port 80 is open and available, and no direct SQL traffic is allowed across the firewall. So take the following simple system. A web page (default.aspx) makes a call (string GetData()) that resides in an assembly (Simple.DLL). GetData() uses ADO.NET to open a connection, execute a SQL call, retrieve the data, and return the data to the caller. However, since only port 80 is available and no SQL traffic is allowed, what could we do to accomplish our goal? I believe a .NET remoting solution would work, and I have heard of an architecture where a remoting layer proxies the call from Simple.DLL in the DMZ to another Simple.DLL that runs on the protected side. The remoting layer handles the communication between the two DLL’s. Can someone shed some light on how WCF/remoting can help us and how to get started with a solution?

• How have popular iPhone games been ported to Android?

  - by Cirrostratus

  I am not asking how could they have been, I want to know the real answer. Doodle Jump, Paper Toss and some others have versions on the iPhone and Android that are nearly exactly the same, with the iPhone version coming first. There is a small Objective-C compiler project for Android's NDK but the timing isn't right for these apps. There's also an Android port of Cocos2d but I doubt Doodle Jump used that. Titanium? Doubtful. As their respective code bases grow, I figure it'd get harder and harder to do an exact port from Objective-C to Java every release so I wonder if there is a better way. Are they sharing C++ code for example?

• Limit Connections with semaphores

  - by Robert

  I'm trying to limit the number of connections my server will accept using semaphores, but when running, my code doesn't seem to make this restriction - am I using the semaphore correctly? eg. I have hardcoded the number of permit as 2, but I can connect an unlimited number of clients... public class EServer implements Runnable { private ServerSocket serverSocket; private int numberofConnections = 0; private Semaphore sem = new Semaphore(2); private volatile boolean keepProcessing = true; public EServer(int port) throws IOException { serverSocket = new ServerSocket(port); } @Override public void run() { while (keepProcessing) { try { sem.acquire(); Socket socket = serverSocket.accept(); process(socket, getNextConnectionNumber()); } catch (Exception e) { } finally { sem.release(); } } closeIgnoringException(serverSocket); } private synchronized int getNextConnectionNumber() { return ++numberofConnections; } // processing related methods }

• ImageMagick on Mac OSX Snow Leopard. Is there any way to get it to compile and run?

  - by ?????

  It seems that I have more trouble getting standard Unix things to run on Snow Leopard than any other platform--including Windows cygwin For the past couple of days, I've been trying to get ImageMagick to run on Snow Leopard. The most obvious way, Mac Ports, fails: tppllc-Mac-Pro:ImageMagick-sl swirsky$ sudo port install imagemagick ---> Computing dependencies for p5-locale-gettext ---> Configuring p5-locale-gettext Error: Target org.macports.configure returned: configure failure: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_perl_p5-locale-gettext/work/gettext-1.05" && /opt/local/bin/perl Makefile.PL INSTALLDIRS=vendor " returned error 2 Command output: checking for gettext... no checking for gettext in -I/opt/local/include -arch i386 -L/opt/local/lib -lintl...gettext function not found. Please install libintl at Makefile.PL line 18. no Error: Unable to upgrade port: 1 Error: Unable to execute port: upgrade xorg-libXt failed Before reporting a bug, first run the command again with the -d flag to get complete output. tppllc-Mac-Pro:ImageMagick-sl swirsky$ Not wanting to spend another two days figuring out why my libintl doesn't have a "gettext" function, I tried a different route: the script mentioned here: http://github.com/masterkain/ImageMagick-sl This script downloads and installs an ImageMagic independently of MacPorts issues tppllc-Mac-Pro:ImageMagick-sl swirsky$ /usr/local/bin/convert dyld: Library not loaded: /opt/local/lib/libiconv.2.dylib Referenced from: /opt/local/lib/libfontconfig.1.dylib Reason: Incompatible library version: libfontconfig.1.dylib requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0 Trace/BPT trap It downloads everything and compiles fine, but fails when I try to run it, with the message above. So now I'm two steps away from ImageMagick, trying to get a newer libiconv on my machine. I downloaded the latest libiconv, compiled and built it. I put the resulting library in /opt/local/lib, and I still get the same error message: tppllc-Mac-Pro:.libs swirsky$ sudo mv libiconv.2.dylib /opt/local/lib/libiconv.2.dylib tppllc-Mac-Pro:.libs swirsky$ convert dyld: Library not loaded: /opt/local/lib/libiconv.2.dylib Referenced from: /opt/local/lib/libfontconfig.1.dylib Reason: Incompatible library version: libfontconfig.1.dylib requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0 Trace/BPT trap Now here's something interesting. The error message shows it's looking in /opt/local/lib/libiconv.2.dylib. otools -L shows that this does implement 8.0.0: tppllc-Mac-Pro:.libs swirsky$ otool -L /opt/local/lib/libiconv.2.dylib /opt/local/lib/libiconv.2.dylib: /usr/local/lib/libiconv.2.dylib (compatibility version 8.0.0, current version 8.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.0) tppllc-Mac-Pro:.libs swirsky$ And, for good measure, I set the DYLD_LIBRARY_PATH to make sure this directory is the one for dynamic libraries. So even though I do have a library that provides 8.0.0, it's being seen as 7.0.0! Any ideas why this would happen? So here's my question: Is it possible to get ImageMagick to run on OSX Snow Leopard? Are there any binary distributions that have static libraries baked in so I don't have to worry about these issue/

• abandon session in asp.net on browser close..kill session cookie

  - by Tuviah

  So I have a website where I use session start and end events to track and limit open instances of our web application, even on the same computer. On page unload i call a session enabled page method which then called session.abandon. This triggers session end event and clears the session variable but unfortunately does not kill the session cookie!! as a result if other browser instances are open there are problems because their session state just disappeared...and much worse than this when I open the site again with the zombie session still not expired, I get multiple session start and session end events on any subsequent postbacks. This happens on all browsers. so how do I truly kill the session (force the cookie to expire)
