• Windows Mobile deletes my Contacts when deleting a partnership

  - by bitbonk

  Sometimes when I reinstall my PC get a new Work PC or buy a new home PC ,ActiveSync, now the Device Center asks me to delete an existing partnership to setup a partnership with the new PC, since only two partnerships are allowed. When I delete that partnership all contacts that originally came from that partnership get deleted too. How can I prevent that from happening. Do I really always have to remember to frequently backup all my contacts in a safe place? How much redundancy is needed. I hat them on one of my PCs and on my phone.

• How can I set up VLANs in a way that won't put me at risk for VLAN hopping?

  - by hobodave

  We're planning to migrate our production network from a VLAN-less configuration to a tagged VLAN (802.1q) configuration. This diagram summarizes the planned configuration: One significant detail is that a large portion of these hosts will actually be VMs on a single bare-metal machine. In fact, the only physical machines will be DB01, DB02, the firewalls and the switches. All other machines will be virtualized on a single host. One concern that has been is that this approach is complicated (overcomplicated implied), and that the VLANs are only providing an illusion of security, because "VLAN hopping is easy". Is this a valid concern, given that multiple VLANs will be used for a single physical switch port due to virtualization? How would I setup my VLANs appropriately to prevent this risk? Also, I've heard that VMWare ESX has something called "virtual switches". Is this unique to the VMWare hypervisor? If not, is it available with KVM (my planned hypervisor of choice)?. How does that come into play?

• Disappearing Windows Explorer pinned items

  - by surfmadpig

  This has happened twice now in three months: After rebooting, ALL the pinned items from my Windows Explorer taskbar jumplist are gone. Also, recent items from Windows Explorer are much fewer, only one or two if I remember correctly. After the first time I re-pinned the items I wanted, but about a month later it happened again. I re-pinned All other pinned items in other jumplists (e.g. Word) are fine and have never disappeared. Googling for the problem showed that ccleaner can affect this, but I personally do NOT use any cleaners or related progs on this machine. I also think that both times it happened it was after a windows update, although I can't recall what kind of update it was. After each time, Little Registry Editor showed invalid references in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\RecentDocs , but I had NOT used it prior to the deletions. Any ideas on why this happens and how to prevent it?

• Munin fills server memory

  - by danilo

  In the last weeks, it happened several times to me that my vserver (Debian Lenny) was out of RAM (500M) and therefore wasn't able to run apache anymore. When looking at the processes with top, I saw that there were many open munin-limits and munin-cron processes that consumed most of the memory. My guess would be that sometimes Apache temporarily needs more memory, which prevents munin-cron from running. And if munin-cron isn't able to stop itself, it would fill the memory until nothing is left. I don't know whether this guess is true, but could maybe someone know what the problem is and how to prevent it? If necessary I'll remove munin, but I'd prefer to keep it running.

• Share internet with my phone?

  - by Kenneth Cochran

  Most people want to use their cellphone as a modem for their computer, commonly referred to as 'tethering'. I'm actually interested in doing the opposite: Sharing my landline internet connection(which is much faster than any 3G service) with by cellphone. My phone is a Verizon BlackBerry Curve 8330 and it has USB and bluetooth connections. I know both USB and Bluetooth are capable of supporting tcp/ip traffic what's not so clear is: Is IP over USB or Bluetooth standardized? Is it supported on my phone? Has my cellphone company crippled my phone to prevent me from using it?

• Removing past searches from Google Chrome's omnibar

  - by Ram Rachum

  One time I searched for Orange Juice in Chrome's Omnibar. Now, every time I start typing Orange, I get the search suggestion: How do I get Chrome to stop offering me this search suggestion? If I need to edit some config file, I can do that. Please don't post answers if you haven't ensured they work first. (This is intended to prevent people from answering "Press Shift-Delete.") Clarification: I'd prefer a solution in which I can selectively delete entries, not just by time segment. I also prefer a solution that does not involve cancelling any Chrome functionality.

• Text message intent - catch and send

  - by Espen

  Hi! I want to be able to control incoming text messages. My application is still on a "proof of concept" version and I'm trying to learn Android programming as I go. First my application need to catch incomming text messages. And if the message is from a known number then deal with it. If not, then send the message as nothing has happened to the default text message application. I have no doubt it can be done, but I still have some concern and I see some pitfalls at how things are done on Android. So getting the incomming text message could be fairly easy - except when there are other messaging applications installed and maybe the user wants to have normal text messages to pop up on one of them - and it will, after my application has had a look at it first. How to be sure my application get first pick of incomming text messages? And after that I need to send most text messages through to any other text message application the user has chosen so the user can actually read the message my application didn't need. Since Android uses intents that are relative at best, I don't see how I can enforce my application to get a peek at all incomming text messages, and then stop it or send it through to the default text messaging application...

• Long running transactions with Spring and Hibernate?

  - by jimbokun

  The underlying problem I want to solve is running a task that generates several temporary tables in MySQL, which need to stay around long enough to fetch results from Java after they are created. Because of the size of the data involved, the task must be completed in batches. Each batch is a call to a stored procedure called through JDBC. The entire process can take half an hour or more for a large data set. To ensure access to the temporary tables, I run the entire task, start to finish, in a single Spring transaction with a TransactionCallbackWithoutResult. Otherwise, I could get a different connection that does not have access to the temporary tables (this would happen occasionally before I wrapped everything in a transaction). This worked fine in my development environment. However, in production I got the following exception: java.sql.SQLException: Lock wait timeout exceeded; try restarting transaction This happened when a different task tried to access some of the same tables during the execution of my long running transaction. What confuses me is that the long running transaction only inserts or updates into temporary tables. All access to non-temporary tables are selects only. From what documentation I can find, the default Spring transaction isolation level should not cause MySQL to block in this case. So my first question, is this the right approach? Can I ensure that I repeatedly get the same connection through a Hibernate template without a long running transaction? If the long running transaction approach is the correct one, what should I check in terms of isolation levels? Is my understanding correct that the default isolation level in Spring/MySQL transactions should not lock tables that are only accessed through selects? What can I do to debug which tables are causing the conflict, and prevent those tables from being locked by the transaction?

• Preventing logrotate's dateext from overwriting files

  - by Thirler

  I'm working with a system where I would like to use the dateext function of logrotate (or some other way) to add the date to a logfile when it is rotated. However in this system it is important that no logging is missing and dateext will overwrite any existing files (which will happen if logrotate is called twice on a day). Is there a reliable way to prevent dateext to overwrite existing files, but instead make another file?. It is acceptable that either no rotate happens or a file is created with a less predictable name (date with an extra number, or the time or something).

• How to query MySQL for exact length and exact UTF-8 characters

  - by oskarae

  I have table with words dictionary in my language (latvian). CREATE TABLE words ( value varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci; And let's say it has 3 words inside: INSERT INTO words (value) VALUES ('teja'); INSERT INTO words (value) VALUES ('vejš'); INSERT INTO words (value) VALUES ('feja'); What I want to do is I want to find all words that is exactly 4 characters long and where second character is 'e' and third character is 'j' For me it feels that correct query would be: SELECT * FROM words WHERE value LIKE '_ej_'; But problem with this query is that it returs not 2 entries ('teja','vejš') but all three. As I understand it is because internally MySQL converts strings to some ASCII representation? Then there is BINARY addition possible for LIKE SELECT * FROM words WHERE value LIKE BINARY '_ej_'; But this also does not return 2 entries ('teja','vejš') but only one ('teja'). I believe this has something to do with UTF-8 2 bytes for non ASCII chars? So question: What MySQL query would return my exact two words ('teja','vejš')? Thank you in advance

• UITouch Events and Table Views

  - by Andy

  I'm working on a navigation-based iPhone-only app that serves two main purposes: One, to present data in a hierarchical view, allowing users to drill down and eventually edit said data, and, two, to all users to perform a default action when the table view cell is tapped. I now need to offer a small set of options tied to the same data; however, both the didSelectRowAtIndexPath: and accessoryButtonTappedForRowAtIndexPath: methods are obviously taken. So, my options seem to be to implement a double-tap method, wherein the small list of additional options would be presented after (you guessed it) a double-tap on said table row; or, preferably, a tap-and-hold method. From what I can tell, tap-and-hold seems like the way to go in SDK 4.0 - which does me no good right this red-hot minute. I decided to go with the double-tap option, but I'm having a little trouble. First and foremost, the touchesBegan:withEvent: method does not seem to be getting called at all; a breakpoint placed within the method is never called while the application runs, and the table view responds exactly as it did before I inserted the method (which is to say, it performs the default action): - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *aTouch = [touches anyObject]; if (aTouch.tapCount == 2) { [NSObject cancelPreviousPerformRequestsWithTarget:self]; } } Second, I don't really need to handle a single-tap - the didSelectRowAtIndexPath: method can handle the single-tap just fine. The double-tap is the funky one I want to handle. I suspect the answer is going to contain the phrase, "You can't have the table view handle the single-tap and the touchesBegan: method handle the double-tap. The touch handling methods have to handle all of them." I would really appreciate some guidance from some of you who've dealt with this issue. Thanks in advance.

• phpUnit - mock php extended exception object

  - by awongh

  I'm testing some legacy code that extends the default php exception object. This code prints out a custom HTML error message. I would like to mock this exception object in such a way that when the tested code generates an exception it will just echo the basic message instead of giving me the whole HTML message. I cannot figure out a way to do this. It seems like you can test for explicit exceptions, but you can't change in a general way the behavior of an exception, and you also can't mock up an object that extends a default php functionality. ( can't think of another example of this beyond exceptions... but it would seem to be the case ) I guess the problem is, where would you attach the mocked object?? It seems like you can't interfere with 'throw new' and this is the place that the object method is called.... Or if you could somehow use the existing phpunit exception functionality to change the exception behavior the way you want, in a general way for all your code... but this seems like it would be hacky and bad....

• How to get age field in Google Docs form:

  - by Juhele

  we need to create a form asking the clients for their age. Is there any way to create a field where you can only fill in numbers - maybe only 4 numbers like 1976 or 2011. Second alternative could be date. It would be perfect if I could limit the number - something like "not lower than 1800 and not higher than 2012" to prevent invalid numbers. I can create question with drop down list, but creating a list of all possible years would be stupid and incomfortable to choose from. thanks much

• Precision of Interval for PL/SQL Function value

  - by Gary

  Generally, when you specify a function the scale/precision/size of the return datatype is undefined. For example, you say FUNCTION show_price RETURN NUMBER or FUNCTION show_name RETURN VARCHAR2. You are not allowed to have FUNCTION show_price RETURN NUMBER(10,2) or FUNCTION show_name RETURN VARCHAR2(20), and the function return value is unrestricted. This is documented functionality. Now, I get an precision error (ORA-01873) if I push 9999 hours (about 400 days) into the following. The limit is because the default days precision is 2 DECLARE v_int INTERVAL DAY (4) TO SECOND(0); FUNCTION hhmm_to_interval return INTERVAL DAY TO SECOND IS v_hhmm INTERVAL DAY (4) TO SECOND(0); BEGIN v_hhmm := to_dsinterval('PT9999H'); RETURN v_hhmm; -- END hhmm_to_interval; BEGIN v_int := hhmm_to_interval; end; / and it won't allow the precision to be specified directly as part of the datatype returned by the function. DECLARE v_int INTERVAL DAY (4) TO SECOND(0); FUNCTION hhmm_to_interval return INTERVAL DAY (4) TO SECOND IS v_hhmm INTERVAL DAY (4) TO SECOND(0); BEGIN v_hhmm := to_dsinterval('PT9999H'); RETURN v_hhmm; -- END hhmm_to_interval; BEGIN v_int := hhmm_to_interval; end; / I can use a SUBTYPE DECLARE subtype t_int is INTERVAL DAY (4) TO SECOND(0); v_int INTERVAL DAY (4) TO SECOND(0); FUNCTION hhmm_to_interval return t_int IS v_hhmm INTERVAL DAY (4) TO SECOND(0); BEGIN v_hhmm := to_dsinterval('PT9999H'); RETURN v_hhmm; -- END hhmm_to_interval; BEGIN v_int := hhmm_to_interval; end; / Any drawbacks to the subtype approach ? Any alternatives (eg some place to change a default precision) ? Working with 10gR2.

• Character Set Issues when Upgrading from Symfony 2.0.* to Symfony 2.1.*?

  - by Adam Stacey

  I have recently upgraded my staging test site to the latest version of Symfony and updated all the vendors using composer as instructed in the upgrade document that comes with the download. Everything has all updated fine, but I have noticed now that some bits of HTML are not displaying in the Twig templates. I did a comparison with the current live site and it appears to be a character set issue. As an example I had a drop down list that had the following value in: Kitchen Ducting > Ducting Kits > Ducting Kit 4” / 100mm In the updated site the drop-down list item just appeared blank. When I used Twig's raw function it then displayed the item again, but with the dreaded question mark in a black diamond. Kitchen Ducting > Ducting Kits > Ducting Kit 4? / 100mm Things that you should know that may help: The staging test site and live site are both on the same server. In my httpd.conf file I have 'AddDefaultCharset utf-8'. In my php.ini file I have 'default_charset = "utf-8"'. The HTML file served has the Content-Type meta tag 'content="text/html; charset=utf-8"' My database is InnoDB and uses 'utf8' as the default character set and 'utf8_general_ci' as default collation. All tables in the database also use the defaults. I looked into BOM with UTF8, but could not work out if that was a problem or not?

• Flex 4 / Flash 4 Add to Current State

  - by user163757

  I am having a little difficulty working with states in Flex (or Flash) 4. Lets say that my application has three states; the default (base) state, state 1, and state 2. State 1 should always be based on the base state, that's easy enough to accomplish. However, I would like state 2 to be based on the current state (either base or state 1). I can't for the life of me figure it out. I tried setting the basedOn property of state 1 to "this.currentState", but that just crashes my browser. <s:states> <s:State name="default"/> <s:State name="state1"/> <s:State name="state2" basedOn="{this.currentState}"/> </s:states> <s:TitleWindow id="configWindow" includeIn="state1" width="250" height="100%" close="configWindow_closeHandler(event)"/> <s:Panel id="settings" includeIn="state2" width="200" height="200"/>

• How do I set up routes to enable me to call different actions on the same controller?

  - by Remnant

  I am building my first asp.net mvc application for learning and development purposes and have come across an issue that I'd like some guidance with. Suppose I have a controller with two actions as follows: public class MyController : Controller { public ActionResult Index() { dbData = GetData("DefaultParameter") return View(dbData); } public ActionResult UpdateView(string dbParameter) { dbData = GetData("dbParameter"); return View(dbData); } } On my webpage I have the following: <% using (Html.BeginForm("UpdateView", "MyController")) %> <% { %> <div class="dropdown"><%=Html.DropDownList("Selection", Model.List, new { onchange="this.form.submit();" })%></div> <% } %> I have the following route in Global.asax: public static void RegisterRoutes(RouteCollection routes) { routes.MapRoute("Default", "{controller}", new { controller = "MyController", action = "Index"}); } The issue I am having is as follows: When I use the dropdownlist I get an error saying that /MyController/UpdateView could not be found. It therefore seems that I need to add an additional route as follows: routes.MapRoute("Default", "{controller}", new { controller = "MyController", action = "UpdateView"}); However, this causes two new issues for me: Due to the hierachy within the routing list, the similarity of the routes means that the one that appears first in the list is always executed. I don't see why I need to create another route for UpdateView. All I want to do is to retrieve new data from the database and update the view. I don't see what this has to do with the URL schema. It feels like I have gone down the wrong track here and I have missed something quite fundamental?

• How to lock the c prompt?

  Is there anyway to lock the command prompt? I need my computer to require a password to use the command prompt. I lock the workstation occasionally but sometimes I forget and if I could just prevent my roommate from doing the "c: net user user *" to change my password it would be great. I do not want to have to use the rundll.32 user command with script to automatically lock the computer. Just a way to lock the c prompt. Sorry for not saying this earlier, I'm running a vista 32bit Asus gene II motherboard with a core i7 CPU

• rsync - how to set/keep directory permissions?

  - by Dylan

  I'm using CwRsync to connect from my Windows development machine to a linux webserver : rsync -avuz -e ./ssh --exclude=".svn" /cygdrive/c/xampp/htdocs/project123/ [email protected]:/home/user123/public_html This syncs my development project directory nicely and fast to the server. But after doing this, all directory properties are reset to the local user 'user123' only, so the website is not available anymore. I need to manually reset those properties. Why is this happening, and how to prevent it? PS. coming from a Windows environment I'm having a really hard time understanding rsync. I copied the above command from some examples... just need to get this one small thing working too...

• Problem with document.location.href

  - by novellino

  Hello, I am new to Javascript and Web development and I have a question regarding the document.location.href. I am using a cookie for storing the language the user prefers and then load the english or the swedish version depending on the language. The default language in the beginning is the same as the browser's language, and my index.jsp is the swedish one. The first time everything works fine. The problem is when the cookie exists already. The basic code is: if (language!=null && language!=""){ if (language=="en-US" || language=="en-us") document.location.href = "en/index.jsp"; } else{ //Explorer if (navigator.userLanguage) language = navigator.userLanguage; //other browsers else language = (navigator.language) ? navigator.language : navigator.userLanguage; if (language!=null && language!=""){ setCookie('language', language, 365, '/', 'onCheck'); if (language=="en-US" || language=="en-us") document.location.href = "en/index.jsp"; else if(language=="sv") document.location.href="index.jsp"; } } When the cookie exists we enter the first "if", and there, if the language is swedish it opens the default blabla/index.jsp page. When the language is set to engish it should open the blabla/en/index.jsp but instead it opens the blabla/en/en/index.jsp which of course is wrong. Does anyone know what I am doing wrong?? Thanks

• How to proxy and encrypt all my internet traffic with Win7 and Win2008R2?

  Hi, I have a Windows 7 laptop and a Windows 2008 R2 server. How can I encrypt and route all my internet request from the Win7 laptop to the Win2008R2 server? I guess the server would be called a proxy? Goal is to prevent unencrypted network snooping. I found this article about using SSH, but I would prefer an official windows integrated solution. What's the Microsoft "way" on this? http://lifehacker.com/237227/geek-to-live--encrypt-your-web-browsing-session-with-an-ssh-socks-proxy I would like this to work for all internet traffic, not just browser traffic and I would like to set this up on many Win7 clients.

• Is there a useDirtyFlag option for Tomcat 6 cluster configuration?

  - by kevinjansz

  In Tomcat 5.0.x you had the ability to set useDirtyFlag="false" to force replication of the session after every request rather than checking for set/removeAttribute calls. <Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster" managerClassName="org.apache.catalina.cluster.session.SimpleTcpReplicationManager" expireSessionsOnShutdown="false" **useDirtyFlag="false"** doClusterLog="true" clusterLogName="clusterLog"> ... The comments in the server.xml stated this may be used to make the following work: <% HashMap map = (HashMap)session.getAttribute("map"); map.put("key","value"); %> i.e. change the state of an object that has already been put in the session and you can be sure that this object still be replicated to the other nodes in the cluster. According to the Tomcat 6 documentation you only have two "Manager" options - DeltaManager & BackupManager ... neither of these seem to allow this option or anything like it. In my testing the default setup: <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/> where you get the DeltaManager by default, it's definitely behaving as useDirtyFlag="true" (as I'd expect). So my question is - is there an equivalent in Tomcat 6? Looking at the source I can see a manager implementation "org.apache.catalina.ha.session.SimpleTcpReplicationManager" which does have the useDirtyFlag but the javadoc comments in this state it's "Tomcat Session Replication for Tomcat 4.0" ... I don't know if this is ok to use - I'm guessing not as it's not mentioned in the main cluster configuration documentation.

• SIGABRT on iPhone when changing xib

  - by Boz

  I've just finished off an app for the iPhone which, until today, ran fine on the iPhone simulator and actual devices. I tried changing the xib which is loaded in the applicationDidFinishLaunching method in my application delegate class - all I did was change the string in initWithNibName. When I launch the app on the simulator, the Default.png image is shown, then the app crashes with an uncaught exception. When running on a device, the Default.png image is shown for about 10 seconds, the UI is never loaded and I get 'GDB: Program received signal: "SIGABRT".' on the Xcode status bar. Debugging shows that applicationDidFinishLaunching is never actually reached before the app crashes. Setting the starting xib back to the original solves the issue, but now I've made a change and saved it in the Interface Builder and the app shows the same issues as above - I've made no code changes at all. Is this a memory issue, or a known issue of a common mistake? NOTE: I've made no code changes whatsoever, and the only changes I've made to the xib are cosmetic, the IBOutlets are all intact.
