• What's the best approach when it comes to updating a production(on ec2) machine that can't go down?

  - by Ryan Detzel

  We have three main servers on ec2, web, database, and search. I logged in today to find: 77 packages can be updated. 45 updates are security updates. which scares the crap out of me so I want to update these machines asap but I'm scared to just run the updates on a live running system. Is this safe to do, what's the best approach when it comes to doing security updates on production machines?

• Home server running 2008 R2 intermittently bringing our internet down by creating a large amount of connections [closed]

  - by Philip Strong

  Possible Duplicate: My server's been hacked EMERGENCY My Server 2008 R2 home server is intermittently (every 30 minutes or so, for about 3-4 minutes) creating a huge amount of connections which reaches the 4096 connection limit, thus effectively DOSing our internet connection. I've run a couple of network traffic monitors, and it appears to be a system process causing the problem. I thought I'd fixed it by reinstalling Comodo Antivirus, but it appears that wasn't the problem. Any thought? Thanks in advance.

• iPhone SDK: How do I create an overlay drop-down menu?

  - by arooaroo

  Hi, I have a UIViewController containing its UIView which occupies the available screen (inbetween the tabbar and nav bar). I'd now like to add a simple toolbar which is situated at the top of the UIView which will contain some buttons. One of the buttons should display a drop down menu which is displayed as an overlay over the UIView. I'd quite like this menu to be a UITable as it could contain many items. The problem I'm having is I can't see the best way to go about this. I'm wondering whether there's a simple strategy. Here's an example of the type of feature I'm looking for... Menu hidden: http://www.flickr.com/photos/peterevers/3147678219/in/photostream/ Menu displayed: http://www.flickr.com/photos/peterevers/3148550320/ I expect the above example is emulated in UIWebView using HTML/CSS. Is there a "proper" way? TIA

• Problems with tk85.dll when shutting down an application that embeds the Python interpreter.

  - by George Edison

  My C++ application embeds the Python interpreter, but seems to be having some trouble when it shuts down. Right after the main window closes, I get a segmentation fault (this is Windows, but we'll call it a segmentation fault anyway). The stack trace is below: #0 102AD580 tk85!Tk_MainWindow() (C:\Users\Nathan\Documents\Projects\PowerPad 1.3\bin\Debug\lib\tk85.dll:??) #1 103082DD tk85!XSetStipple() (C:\Users\Nathan\Documents\Projects\PowerPad 1.3\bin\Debug\lib\tk85.dll:??) #2 102214A3 ??() (C:\Users\Nathan\Documents\Projects\PowerPad 1.3\bin\Debug\lib\tk85.dll:??) #3 10220000 ??() (??:??) #4 00000000 ??() (??:??) Where would I even begin to debug this problem?

• displaying keyboard raises memory... but it never comes down iPhone

  - by Joshep Freeman

  Hello again. I encountered a weird behavior in memory just by displaying the default keyboard. I've just created a project with an .xib file for testing purposes. This .xib file has an UITextField element in it and it's connected in the .h via: @property(nonatomic, retain) IBOutlet UITextField *sometext; The .m has no changes but: - (void)viewDidAppear:(BOOL)animated { [someText becomeFirstResponder]; } As you see it's very very simple. The problem is that once the keyboard is shown, the memory allocated for it NEVER goes down. I've tested this scenario in another project with the only difference of having two .xib files. Standar pushViewController and popViewController calls are made. Instruments show an increase of 600kb in memory allocations [which are a lot more in the actual iPhone device]. All in all, hehehe. My question is: How do I release the memory allocated for the keyboard?.

• How to tell if XUL menupopup opens down or up?

  - by Jon

  I have an extension that can be placed on any toolbar (like the bookmarks, menu or status bars). In general, the context menu opens downward, but when placed on the status bar and Firefox is closed to the bottom of the screen, the context menu opens upward. I'd like to try reordering the context menu based on its up or down orientation, so that the same options are always closest to the mouse. For example, when opened downward it appears like this: -- (mouse) --------------- - MenuItem A - --------------- - MenuItem B - --------------- - MenuItem C - --------------- - ....... - --------------- When it opens upwards its like this: --------------- - MenuItem A - --------------- - MenuItem B - --------------- - MenuItem C - --------------- - ....... - --------------- -- (mouse) However, I'd like "MenuItem A" to appear closest to the mouse at all times, since its the most common item. I can render the items dynamically, so I really just need to find out the orientation.

• Rotate image in Quartz? Image is upside down! (iPhone)

  - by Johannes Jensen

  I don't want to transform the ENTIRE context. I'm making a game with Quartz, and I'm drawing my player with lines, rects and ellipses. And then I have diamong.png which I rendered at 0,0 in the top left of the screen. Problem is... It renders upside down! How would I rotate it 180 degrees? Here's some of my code: CGImageRef diamondImage = CGImageRetain([UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"Diamond.png" ofType:nil]].CGImage); CGContextDrawImage(context, CGRectMake(0, 0, 32, 24), diamondImage); If it's of any help, I'm using Landscape mode, with home button to the right. It's defined both in my .plist, and in my ViewController's -shouldAutorotateToInterfaceOrientation:interfaceOrientation: How would I rotate/transform it?

• C# WPF: Combobox isn't jumping down the list as I type when I use a multiconvert on it.

  - by michael paul

  Basically, I have a combobox that is built by doing multibinding (multiconverter) for the memberdisplaypath. The problem is if the combobox is selected and I start typing, it doesn't jump down the list. Doesn't it go by what's displayed in the combobox for typing? That is, if the combobox is setup like so: //value/display (please disregard how weird the numbering is...) //ref - the value is built upon an observablecollection of a class. ref / "" ref / "10 - Very much agree." ref / "15 - Somewhat agree." ref / "19 - No weight." ref / "23 - Somwhat disagree." ref / "33 - Very much disagree." If the user presses the "1" key it should jump to "10 - Very much agree." But, instead it just sits there...

• Red Hat cluster: Failure of one of two services sharing the same virtual IP tears down IP

  - by js.

  I'm creating a 2+1 failover cluster under Red Hat 5.5 with 4 services of which 2 have to run on the same node, sharing the same virtual IP address. One of the services on each node needs a (SAN) disk, the other doesn't. I'm using HA-LVM. When I shut down (via ifdown) the two interfaces connected to the SAN to simulate SAN failure, the service needing the disk is disabled, the other keeps running, as expected. Surprisingly (and unfortunately), the virtual IP address shared by the two services on the same machine is also removed, rendering the still-running service useless. How can I configure the cluster to keep the IP address up?

• How should I build a privacy drop-down (select) menu?

  - by animuson

  I'm trying to build something similar to Facebook's privacy selection menu, except without the 'custom' option. It will only list a few options such as 'show to all', 'show to friends only', or 'completely hidden'. Right now I'm thinking of using simple JavaScript to change a hidden input field to the new value they click on, so if they clicked on the division for 'show to friends only' it would change the corresponding field, say 'email_privacy', to 1. Is there a better way to do this or am I pretty much on track? P.S. I am not planning on using a select element, I was planning on building a custom drop-down menu using CSS since select elements are so highly non-customizable. I'm doing it this way to save space, rather than having this massive selection menu at the right which takes up a bunch of space. Note: I'm not really interested in using jQuery, that's just extra libraries and crap that I don't want to load. I can do it in JavaScript just as easily so I might as well use that.

• Have you ever turned-down morally questionable or unethical web work?

  - by louism

  i'm just wondering if you guys have ever had a situation where you were offered a web development project which you turned down because you felt it was unethical or morally questionable. i've only had this once. i was offered a contract to develop a website for a meat abattoir (i.e. slaughterhouse). what's the problem you may ask? i'm vegetarian. i know, it's not an egregious dilemma, but it just didn't seem right to me. i have a female graphic designer friend who declined to work on a sex toys website where she was working at the time. funny thing is, it wouldn't bother me to work on a porn site (as long as it wasn't anything shifty - e.g. dwarfs + donkeys, that sort of thing). anyone else ever had a similar experience?

• Best method to cleanly shut down an application launched via another.

  - by JYelton

  I couldn't find any close answers to this, so I'm consulting the experience of SO users: Scenario: I have two small C# winforms applications where one behaves as a server or host, the other as a client. They share data via SQL Server, in terms of configuration settings. I am currently launching the client application (which only needs to run periodically) from the server application via Process.Start() and terminating it via Process.CloseMainWindow() (after finding it in the process list). While it seems clean enough, I wondered if there's a better way. Question: Which way would be best to instruct the client application to shut down: Continue using Process.CloseMainWindow()? Implement WCF between the applications? (I would need help on how to do this.) Set a variable in SQL that the client application checks for? Some other way?

• Find value of selected item in Drop down menu.

  - by Ozaki

  I have a drop down menu in an ASPX page along the lines of: <form> <select name="cars"> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="fiat" selected="selected">Fiat</option> <option value="audi">Audi</option> </select> </form> That is dynamically generated from another controller (value and label). After the user selects one of the options I need to find out what the selected value/label (will be the same) is so I can hit an update button and retrieve the data on that option. What would be the easiest way to find out the value of the user "selected" option?

• How do you determine up/down latency of a web app.

  - by Brodie

  I am trying to work out how to calculate the latency of requests through a web-app (Javascript) to a .net webservice. Currently I am essentially trying to sync both client and server time, which when hitting the webservice I can look at the offset (which would accurately show the 'up' latency. The problem is - when you sync the time's, you have to factor in latency for that also. So currently I am timeing the sync request (round trip) and dividing by 2, in an attempt to get the 'up' latency...and then modify the sync accordingly. This works on the assumption that latency is symmetrical, which it isn't. Does anyone know a procedure that would be able to determine specifically the up/down latency of a JS http request to a .net service? If it needs to involve multiple handshakes thats fine, what ever is as accurate as possible. Thanks!!

• Why does tokyo tyrant slow down exponentially even after adjusting bnum?

  - by HenryL

  Has anyone successfully used Tokyo Cabinet / Tokyo Tyrant with large datasets? I am trying to upload a subgraph of the Wikipedia datasource. After hitting about 30 million records, I get exponential slow down. This occurs with both the HDB and BDB databases. I adjusted bnum to 2-4x the expected number of records for the HDB case with only a slight speed up. I also set xmsiz to 1GB or so but ultimately I still hit a wall. It seems that Tokyo Tyrant is basically an in memory database and after you exceed the xmsiz or your RAM, you get a barely usable database. Has anyone else encountered this problem before? Were you able to solve it?

• How can I track down these Firefox warning messages?

  - by Charles Anderson

  Since I upgraded to jQuery 1.4.4 I've been getting several new warning messages when I run my unit tests in Firefox 3.6.13. Here's a typical one: Warning: Unexpected token in attribute selector: '!'. Source File: http://localhost/unitTests/devunitTests.html Line: 0 Or the even more useful: Warning: Selector expected. Source File: http://localhost/unitTests/ui/editors/iframe2.html?test=15 Line: 0 The web page renders nicely, and all my JavaScript code seems to be running okay too, so I'm reluctant to spend a potentially large amount of time chopping away at my code to track these messages down. However, can anyone suggest what's provoking the warnings?

• Is it faster to count down than it is to count up?

  - by Bob

  Our computer science teacher once said that for some reason it is more efficient to count down that count up. For example if you need to use a FOR loop and the loop index is not used somewhere (like printing a line of N * to the screen) I mean that code like this : for (i=N; i>=0; i--) putchar('*'); is better than: for (i=0; i<N; i++) putchar('*'); Is it really true? and if so does anyone know why?

• How do I get the name of the test method that was ran in a testng tear down method?

  - by Zachary Spencer

  Basically I have a tear down method that I want to log to the console which test was just ran. How would I go about getting that string? I can get the class name, but I want the actual method that was just executed. Class testSomething() { @AfterMethod public void tearDown() { system.out.println('The test that just ran was....' + getTestThatJustRanMethodName()'); } @Test public void testCase() { assertTrue(1==1); } } should output to the screen: "The test that just ran was.... testCase" However I don't know the magic that getTestThatJustRanMethodName should actually be.

• Is it possible to cut down the size of Flex 4 deployments?

  - by Robusto

  My bin-release for a very simple Web project using Flex 4 is weighing in at 1.5MB. 40% of that is taken up by one single file which is over 600K all by itself. Here are the files that take up most of the volume: framework_4.0.0.14159.swz 608KB spark_4.0.0.14159.swz 311KB textLayout_1.0.0.595.swz 153KB There are others as well, but this is over a megabyte right there. All this was fine when I was writing components for a large Flex application, but now I need to do widgets on an HTML page using a CMS. Are all these files really necessary to deploy? Are there things I can do to cut down the weight?

• How to scroll whole visible page down to an anchor with a smooth effect (Scriptaculous or jQuery)?

  - by ChrisBenyamin

  Hey community, I want to create an navigation with anchors. By clicking on a navigation link, the whole visible page should scroll down to the clicked anchor. The most important is the following structure of the page. --------------- (Begin visible browser area) NAV1 nav2 nav3 content --------------- (Begin/end visible browser area) nav1 NAV2 nav3 content --------------- (Begin/end visible browser area) nav1 nav2 NAV3 content --------------- (end visible browser area) Finally all content is in a single document and the height of the current page (selected by the nav-item) has to be calculated (with a JS Library). I prefer PrototypeJS/Scriptaculous and jQuery. The scroll effect should be a smooth slide/ effect. Chris

• What is the correct HTTP status code to send when a site is down for maintenance?

  - by alex

  Is there a HTTP status code to tell Google (and others) to go away, index me again later? Basically, one that semantically tells clients that the site is down for maintenance? The ones I have considered are 304 => Not modified 307 => Temporary redirect 410 => Gone 503 => Service Unavailable I'm leaning towards the last one, but was just curious as to which one was proper choice. Thanks Update Is this the correct way to send it with PHP? header('Status: 503 Service Unavailable');

• Drop down selection not registered when form submitted quickly?!

  - by Abs

  Hello all, I have noticed a strange thing that happens on my web app when the server is under heavy loads (I am remoting on to the Windows Server). I have a drop down box which is generated dynamically (server side). When I make a selection and quickly press the submit button to indicate my selection the next page does not register my selection but if I do it a bit more slowly it will. I have not come across this before, has anyone? I know its a small issue but there are a lot of "trigger happy", including me... should I put a delay before the form is submitted? If I do, I can only guess the right amount of time. Or is there an underlying problem with my web app? Thanks all

• How to track when my application has unexpectedly shut down?

  - by Vilx-

  I'm writing an application whose purpose involves a lot of logging of different events. Among those I would also like to have an event that the application was shut down - even if unexpectedly like because of a power loss. Naturally, when the power goes out I don't get a chance to write anything anywhere. So my idea was to continuously write a timestamp in some known location (say, once per minute), and when the application was next run, it could determine the approximate time of the unexpected shutdown. A precision of 1 minute would be acceptable for me. However I'm worried that caching at the OS and disk level might interfere with this approach. Is there a better way or if not - how to make sure that the data I just wrote is REALLY written out to the physical medium? Added: Oh, almost forgot the buzzword line: Windows XP and above; .NET 3.5; C#.

• How to handle request/response propagation up and down a widget hierarchy in a GUI app?

  - by fig-gnuton

  Given a GUI application where widgets can be composed of other widgets: If the user triggers an event resulting in a lower level widget needing data from a model, what's the cleanest way to be able to send that request to a controller (or the datastore itself)? And subsequently get the response back to that widget? Presumably one wouldn't want the controller or datastore to be a singleton directly available to all levels of widgets, or is this an acceptable use of singleton? Or should a top level controller be injected as a dependency through a widget hierarchy, as far down as the lowest level widget that might need that controller? Or a different approach entirely?
