• Can I configure mod_proxy to use different parameters based on HTTP Method?

  - by Graham Lea

  I'm using mod_proxy as a failover proxy with two balance members. While mod_proxy marks dead nodes as dead, it still routes one request per minute to each dead node and, if it's still dead, will either return 503 to the client (if maxattempts=0) or retry on another node (if it's 0). The backends are serving a REST web service. Currently I have set maxattempts=0 because I don't want to retry POSTs and DELETEs. This means that when one node is dead, each minute a random client will receive a 503. Unfortunately, most of our clients are interpreting codes like 503 as "everything is dead" rather than "that didnt work but please try that again". In order to program some kind of automatic retry for safe requests at the proxy layer, I'd like to configure mod_proxy to use maxattempts=1 for GET and HEAD requests and maxattempts=0 for all other HTTP Methods. Is this possible? (And how? :)

• Questions about linux root file system.

  - by smwikipedia

  I read the manual page of the "mount" command, at it reads as below: All files accessible in a Unix system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. The mount command serves to attach the file system found on some device to the big file tree. My questions are: Where is this "big tree" located? Suppose I have 2 disks, if I mount them onto some point in the "big tree", does linux place some "special marks" in the mount point to indicate that these 2 "mount directories" are indeed seperate disks?

• Generate or update a PDF to include an encrypted, hidden watermark?

  - by Dave Jarvis

  Background Using LaTeX to write a book. When a user purchases the book, the PDF will be generated automatically. Problem The PDF should have a watermark that includes the person's name and contact information. Question What software meets the following criteria: Applies encrypted, invisible watermarks to a PDF Open Source Platform independent (Linux, Windows) Fast (marks a 200 page PDF in under 1 second) Batch processing (exclusively command-line driven) Collusion-attack resistant Non-fragile (e.g., PDF - EPS - PDF still contains the watermark) Well documented (shows example usages) Ideas & Resources Some thoughts and findings: Natural language processing (NLP) watermarks. Apply steganography on a randomly selected image. http://openstego.sourceforge.net/cmdline.html The problem with NLP is that grammatical errors can be introduced. The problem with steganography is that the images are sourced from an image cache, and so recreating that cache with watermarked images will impart a delay when generating the PDF (I could just delete one image from the cache, but that's not an elegant solution). Thank you!

• How much does it wear an SD card to be frequently removed/reinserted?

  - by jtbandes

  My digital camera (a Sony a55) stores photos on an SD card. When I want to transfer these to my computer (a mid-2010 MacBook Pro), I have two options: use the USB cable to connect the camera to the computer, or use the computer's built-in SD card reader. The camera's SD card slot is the standard click-in, click-out (spring-loaded) mechanism. My laptop has a simple slot into which the card slides with a little more resistance than the former (the card slides only about halfway in so it can be easily removed). I notice that the card's contacts now have some shiny marks from one or both of these card slots: Does this type of wear threaten to significantly damage the card? Should I avoid switching the card between slots frequently, to extend its lifetime?

• Finding shapes in 2D Array, then optimising

  - by assemblism

  I'm new so I can't do an image, but below is a diagram for a game I am working on, moving bricks into patterns, and I currently have my code checking for rotated instances of a "T" shape of any colour. The X and O blocks would be the same colour, and my last batch of code would find the "T" shape where the X's are, but what I wanted was more like the second diagram, with two "T"s Current result      Desired Result [X][O][O]                [1][1][1] [X][X][_]                [2][1][_] [X][O][_]                [2][2][_] [O][_][_]                [2][_][_] My code loops through x/y, marks blocks as used, rotates the shape, repeats, changes colour, repeats. I have started trying to fix this checking with great trepidation. The current idea is to: loop through the grid and make note of all pattern occurrences (NOT marking blocks as used), and putting these to an array loop through the grid again, this time noting which blocks are occupied by which patterns, and therefore which are occupied by multiple patterns. looping through the grid again, this time noting which patterns obstruct which patterns That much feels right... What do I do now? I think I would have to try various combinations of conflicting shapes, starting with those that obstruct the most other patterns first.How do I approach this one? use the rational that says I have 3 conflicting shapes occupying 8 blocks, and the shapes are 4 blocks each, therefore I can only have a maximum of two shapes. (I also intend to incorporate other shapes, and there will probably be score weighting which will need to be considered when going through the conflicting shapes, but that can be another day) I don't think it's a bin packing problem, but I'm not sure what to look for. Hope that makes sense, thanks for your help

• Boot failure randomly. Can someone help?

  - by desgua

  I often get stuck at the boot on battery. I can suspend and hibernate without any trouble (even on battery). If I plug the energy cable everything goes right most of the time (edited June 13). Adding "acpi=off" doesn't solve the issue. Disabling power save from LAN at BIOS doesn't solve this too. Memory test seems to be ok: I can even compile a kernel without a problem: Has someone a tip for this? (I have the same questions marks in my mind as the image shows if not more :-/ ) obs.: this is an upgraded installation from Natty alpha. edited I (May 22): I've installed a brand new final 11.04 and got the bug again. edited II (June 13): I thought it was solved but it is not. After spending eight days off, the same problem happened even with the power cable connected. I had to reboot about 6 times until success. edited III (June 14): I can boot (even with battery) if I disconnect the cable and take off the battery for a few seconds. This lead me to conclude that maybe something is kept into memory of some hardware. Maybe or maybe not related but I also have touchpad issues (jumps) with this machine. edited IV (June 25): I opened gconf-editor and went to apps gnome-power-manager and disabled everything possibly related to suspend or hibernate. No help. Also I grabbed a Fedora live usb pendrive and got the same problem: So I think it is a hardware problem related issue.

• Un-table a cell range in Excel 2007

  - by Joe

  In Excel 2007, if you highlight a block of cells and then "Format as Table", it doesn't just apply colors and formatting, it somehow marks those cells as being a table. Now I want to get rid of the table, but keep all the cells (i.e. keep the data). So I tried clearing the table style and formatting, but Excel still recognizes those cells as being a table. I can tell because: When I select a cell that was in the table, Excel still displays the "Table Tools / Design" tab I cannot merge cells that were in the table <- this is what's annoying me So, how do I un-table those cells? I want to keep all the cell data and formatting, but have Excel not recognize them as a table.

• Are Snow Leopard text substitutions scriptable?

  - by yonatron

  I prefer using typographical quotation marks when possible, so I love the Smart Quotes part of Snow Leopard’s text replacement feature. But there are a few cases in which I need to toggle it, and it’s a pain to do so from the contextual menu when I’m typing. Is there any way (preferably via AppleScript, but I can deal with other suggestions) to toggle specific types of text replacement for the frontmost text-input control? And if so, what’s a good way to assign it to a globally-accessible keyboard shortcut (via 3rd-party app if necessary)?

• Friday Stats

  - by jjg

  As some of you may have noticed, we've recently opened a new repository in the Code Tools project for small utilities which can be used to gather info about the OpenJDK code base and builds. 1 The latest addition is a utility for analyzing the class file versions in a collection of class files. I've posted an example set of results from analyzing the class files in an OpenJDK build on Linux. 2. Most of the files are version 52 files as you would expect, but there is a surprising number of version 51 and 50 files, as well as a handful of v45.3 files as well. Digging deeper, it turns out that Nashorn is still using version 51 class files, and the Serviceability Agent is still using version 50 class files and one 45.3 class file, leaving the remainder of the 45.3 class files coming from RMI. For more info on the different class file versions, see Joe Darcy's class file version decoder rIng. Thanks to Stuart Marks for planting the seed for the class file version tool. See the project page, repo, and mail archive. http://cr.openjdk.java.net/~jjg/cfv-summary/open/

• Monit send alert to nagios NSCA

  - by mYzk

  I want to monitor a web with monit check host function and if the site is down then alert it to nagios nsca so it sends the info to nagios and nagios marks it as status OK or host down for example. The problem is that how can I make the monit alert fuction send the info to nagios nsca. I am not sure that this will work, but what I came up with is: set alert exec 'echo -e "nagios nsca format" | /usr/local/nagios/bin/send_nsca -H serveraddress -c /usr/local/nagios/etc/send_nsca.cfg' Would this work and is it the best solution to work with or can it be done some other way?

• Dealing with bad/incomplete/unclear specifications?

  - by eagerMoose

  I'm working on a project where our dev team gets the specifications from the business part of the company. Both the business management and the IT management require estimates and deadline projections, as they should. The good thing is that estimates are mostly made by the actual developers who get to do the required features. The bad thing is that the specifications are usually either too simple (it turns out you're left with a lot of question marks over your head because a lot of information seems to be missing) or too complex(up to the point that you can't even visualize where everything would "fit" in the app). More often than not, the business part of the specs are either incomplete or unaware of what can and can't be done (given the previously implemented business logic). Dev team is given about a day per new spec to give an estimate and we do try to clear uncertainties, usually by meeting up with whoever did the spec. Most of the times it turns out that spec writers haven't really thought everything through, and it's usually only when we start designing and developing that we end up in trouble, as a lot of the spec seems to have holes. How do you deal with this? Are you generous on estimates in advance?

I then install Acronis Disk Director (which detects it) but marks it as offline. if i try to change it to online, nothing happens. (actually the lights on the HD blink - meaning communication and goes back into offline mode). The lights on the HD return to a solid which mean "working properly".

• Do ALL your variables need to be declared private? [closed]

  - by skizeey

  Possible Duplicate: Why do we need private variables? I know that it's best practice to stay safe, and that we should always prevent others from directly accessing a class' properties. I hear this all the time from university professors, and I also see this all the time in a lot of source code released on the App Hub. In fact, professors say that they will actually take marks off for every variable that gets declared public. Now, this leaves me always declaring variables as private. No matter what. Even if each of these variables were to have both a getter and a setter. But here's the problem: it's tedious work. I tend to quickly lose interest in a project every time I need to have a variable in a class that could have simply been declared public instead of private with a getter and a setter. So my question is, do I really need to declare all my variables private? Or could I declare some variables public whenever they require both a getter and a setter?

• String manipulation functions in SQL Server 2000 / 2005

  - by Vipin

  SQL Server provides a range of string manipulation functions. I was aware of most of those in back of the mind, but when I needed to use one, I had to dig it out either from SQL server help file or from google. So, I thought I will list some of the functions which performs some common operations in SQL server. Hope it will be helpful to you all. Len (' String_Expression' ) - returns the length of input String_Expression. Example - Select Len('Vipin') Output - 5 Left ( 'String_Expression', int_characters ) - returns int_characters characters from the left of the String_Expression.     Example - Select Left('Vipin',3), Right('Vipin',3) Output -  Vip,  Pin  LTrim ( 'String_Expression' ) - removes spaces from left of the input 'String_Expression'  RTrim ( 'String_Expression' ) - removes spaces from right of the input 'String_Expression' Note - To removes spaces from both ends of the string_expression use Ltrim and RTrim in conjunction Example - Select LTrim(' Vipin '), RTrim(' Vipin ') , LTrim ( RTrim(' Vipin ')) Output - 'Vipin ' , ' Vipin' , 'Vipin' (Single quote marks ' ' are not part of the SQL output, it's just been included to demonstrate the presence of space at the end of string.) Substring ( 'String_Expression' , int_start , int_length ) - this function returns the part of string_expression. Right ( 'String_Expression', int_characters ) - returns int_characters characters from the right of the String_Expression.

• Mail sent from local Postfix marked as "possible phishing" in Outlook

  - by leo grrr

  Hi folks, Sorry for the newbie question--this is not my area of expertise by a long shot. I work at a small development shop and we finally got around to doing code reviews. (Yay!) I set up an instance of Review Board -- an open-source code review tool -- on one of our local servers but it doesn't seem to like talking to our hosted Exchange server to send notification emails. I decided to just install Postfix on that same box and send mail from localhost, which is working much more reliably, but Outlook disables all links in the email announcements and marks it as possible phishing. What is making these emails look suspicious and what can I change? Would the best thing be to figure out how to relay to Exchange from Postfix? Thanks!

• 7.0.1 and Photoshop openGL requirements

  - by mcgd

  Hi, I'm running Workstation 7.0.1 on a 64-bit Linux host, with a Vista guest, and the Aero theme works a treat - full marks for getting that working! However, when running Photoshop there are some operations (like interactive image rotation) that seem to require graphics support that VMWare doesn't have - attempting to do these operations returns an error that the functionality "only works with OpenGL enabled windows". It seems that it needs OpenGL 2.0 and Shader Model 3.0 which I gather are supported under Workstation 7 - do I need to put in additional settings of some kind? I've updated to the right version of VMWare Tools, and the video driver is listed as "VMWare SVGA 3D (Microsoft Corporation - WDDM)". I see that in 6.5 there was an option to switch between the beta WDDM driver and the SVGAII driver, but I assume the features of both of these would have been merged into the standard driver in 7.0? Thanks -Matthew

Now the boss wants me to work from home, so I want to share my Asus display with a Windows XP laptop. No doubt once my wife sees this, she will want to do the same thing, but with a Windows 7 laptop. So what I would like, I think, is your recommendations for a KVM switch (or better solution) that allows the Mac and a (windows 7 or windows xp) laptop to share the Asus display. Bonus marks if they can share Apple keyboard and magic mouse, but am quite happy to use separate mouse keyboards. The MacPro is the one that is always connected, the laptops come and go. Any ideas? Thanks in advance for any help.

• Scroll bar for vim(curses-based one, not gvim)?

  As a Linux user, I have been quite comfortable with CLI and TUI tools, but I miss the little scrollbar present in almost every GUI program. It has always been easier for me to know how long the file is and where I am from the scrollbar instead of "9752 lines, 24%". What I expect is a ASCII scrollbar that looks like | | | | # # # | | | and I can configure to appear on the left or right (and if on the left, the relative position to line numbers and fold marks). Is there already a Vim plugin to do this, or how can I write my own one? Vim's plugin framework doesn't seem to support such UI modifications directly.
