• How to translate formulas into form of natural language?

  - by Ricky

  I am recently working on a project aiming at evaluating whether an android app crashes or not. The evaluation process is 1.Collect the logs(which record the execution process of an app). 2.Generate formulas to predict the result (formulas is generated by GP) 3.Evaluate the logs by formulas Now I can produce formulas, but for convenience for users, I want to translate formulas into form of natural language and tell users why crash happened.(I think it looks like "inverse natural language processing".) To explain the idea more clearly, imagine you got a formula like this: 155 - count(onKeyDown) >= 148 It's obvious that if count(onKeyDown) 7, the result of "155 - count(onKeyDown) = 148" is false, so the log contains more than 7 onKeyDown event would be predicted "Failed". I want to show users that if onKeyDown event appears more than 7 times(155-148=7), this app will crash. However, the real formula is much more complicated, such as: (< !( ( SUM( {Att[17]}, Event[5]) <= MAX( {Att[7]}, Att[0] >= Att[11]) OR SUM( {Att[17]}, Event[5]) > MIN( {Att[12]}, 734 > Att[19]) ) OR count(Event[5]) != 1 ) > (< count(Att[4] = Att[3]) >= count(702 != Att[8]) + 348 / SUM( {Att[13]}, 641 < Att[12]) mod 587 - SUM( {Att[13]}, Att[10] < Att[15]) mod MAX( {Att[13]}, Event[2]) + 384 > count(Event[10]) != 1)) I tried to implement this function by C++, but it's quite difficult, here's the snippet of code I am working right now. Does anyone knows how to implement this function quickly?(maybe by some tools or research findings?)Any idea is welcomed: ) Thanks in advance.

• Gwibber only launches sometimes

  - by Stephen Judge

  I face this problem where Gwibber only launches sporadically. Sometimes when I click it to launch, it launches and then other times it doesn't. I can't seem to figure out what is preventing it from launching and what sort of information I need to collect, also where to collect it from to make a bug report. I have killed the gwibber-service processes in the System Monitor "it loads three processes called gwibber-service, is this normal" several times and tried to launch Gwibber again, but this doesn't seem to work. The process just called gwibber starts, then the three gwibber-service processes start, then the gwibbber process ends and the three gwibber-service processes remain but the application is still not launching. Generally, I want to know are other people facing the same problem. If someone can give me some guidance on how to triage this problem and get the information need to make a bug report I would be grateful. The upside to this though is at least when it is not launching it is preventing me from wasting endless hours reading my streams on Identi.ca and Twitter, so it is a bit Workrave for microblogging. In which case maybe I shouldn't fix this problem :-)

• Podcast Show Notes: By Any Other Name: Governance and Architecture

  - by Bob Rhubart

  The OTN ArchBeat Podcast returns from a brief summer hiatus with a three-part conversation about IT architecture and governance. My guests for this conversation are Eric Stephens , an Oracle Enterprise architect and a frequent guest on this program. Joining Eric on the panel is Tim Hall , Senior Director of product management for the Oracle Enterprise Repository, Oracle Service Registry, and Oracle Application Integration Architecture. Tim made his first appearance on ArchBeat as panelist on the recent program featuring Thomas Erl. The Conversation Listen to Part 1:Why it's important to revive the dormant conversation about IT governance. Listen to Part 2 (Sept 19): Balancing functional, technical, operational requirements to meet the challenge of defining appropriate governance "guardrails." Listen to Part 3 (Sept 26): Bringing IT architecture out of the ivory tower to make governance a less intimidating, more collaborative process. Additional Resources Leveraging Governance to Sustain Enterprise Architecture Efforts, an Oracle white paper by Eric Stephens. SOA, Cloud, and Service Technologies, a transcript of an ArchBeat interview with Thomas Erl, Tim Hall, and Demed L'Her, in which Tim says the following about governance: "For a long time people have argued that SOA governance is sort of an awkward name, no one wanted to be audited. There's 50% of the world that think, yes, we're going to have to tops down initiative to address this and there's 50% of the world that says that it feels like a heavy weight process that I want no part of. So what I think we should do is change the name…"

• Compiling PHP with GD crashes with EXC_BREAKPOINT (SIGTRAP) on PPC Mac

  - by Ömer

  First of all, I should say that I have searched the whole Internet for this problem but I couldn't find any solution yet. I have a Mac mini PowerPC (PPC) and I run Apache webserver (httpd-2.2.22) with PHP (5.4.0) and I do all the configure & compilation jobs by myself. If configure with: './configure' '--prefix=/usr/local/php5' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--sysconfdir=/etc' '--with-config-file-path=/etc' '--with-zlib' '--with-zlib-dir=/usr' '--with-openssl=/usr' '--without-iconv' '--enable-exif' '--enable-ftp' '--enable-mbstring' '--enable-mbregex' '--enable-sockets' '--with-mysql=/usr/local/mysql' '--with-pdo-mysql=/usr/local/mysql' '--with-mysqli=/usr/local/mysql/bin/mysql_config' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-mcrypt' then the PHP works flawlessly. But if I add the GD module by adding these to the script above: '--with-gd' '--with-jpeg-dir=/usr/local/lib' '--with-freetype-dir=/usr/X11R6' '--with-png-dir=/usr/X11R6' '--with-xpm-dir=/usr/X11R6' the PHP gets configured and compiled without any errors but it causes EXC_BREAKPOINT (SIGTRAP) (see the Crash Reporter log below) when I request a page which calls PHP module. It's obvious that something related to the GD module is causing this, probably FreeType module because it's present in the log but it may not be definite of course. When the PHP crashes (or more accurately, httpd) the CPU goes 100% for 10 to 15 seconds until it recovers. I need to use the GD module and keep the Mac mini PowerPC. So, what should I do to solve this problem? Process: httpd [79852] Path: /usr/local/apache2/bin/httpd Identifier: httpd Version: ??? (???)

• 64bit server running in 32bit mode using incorrect locale

  - by Derek Ekins

  I have a 64bit server that we are running an application on in 32bit mode. For whatever reason the locale of the 32bit process is coming through as en-US when the server is set to en-GB. I am guessing that the reason for this is there is that the 64bit and WOW64 are not sharring the locale settings. So my question is how do you set the locale for a 32bit process? This is Windows 2003. The application is an asp.net app running under IIS in 32bit mode. This setup is definitely not my choice.

• Open a terminal window & run command, then close the terminal window if command completed successfully?

  - by Caspar

  I'm trying to write a script to do the following: Open a terminal window which runs a long running command (Ideally) move the terminal window to the top left corner of the screen using xdotool Close the terminal window only if the long running command exited with a zero return code To put it in Windows terms, I'd like to have the Linux equivalent of start cmd /c long_running_cmd if long_running_cmd succeeds, and do the equivalent of start cmd /k long_running_cmd if it fails. What I have so far is a script which starts xterm with a given command, and then moves the window as desired: #!/bin/bash # open a new terminal window in the background with the long running command xterm -e ~/bin/launcher.sh ./long_running_cmd & # move the terminal window (requires window process to be in background) sleep 1 xdotool search --name launcher.sh windowmove 0 0 And ~/bin/launcher.sh is intended to run whatever is passed as a command line argument to it: #!/bin/bash # execute command line arguments $@ But, I haven't been able to get the xterm window to close after long_running_cmd is done. I think something like xterm -e ~/bin/launcher.sh "./long_running_cmd && kill $PPID" & might be what I'm after, so that xterm is launched in the background and it runs ./long_running_cmd && kill $PPID. So the shell in the xterm window then runs the long running command and if it completes successfully, the parent process of the shell (i.e. the process owning the xterm window) is killed, thereby closing the xterm window. But, that doesn't work: nothing happens, so I suspect my quoting or escaping is incorrect, and I haven't been able to fix it. An alternate approach would be to get the PID of long_running_cmd, use wait to wait for it to finish, then kill the xterm window using kill $! (since $! refers to last task started in the background, which will be the xterm window). But I can't figure out a nice way to get the PID & exit value of long_running_cmd out of the shell running in the xterm window and into the shell which launched the xterm window (short of writing them to a file somewhere, which seems like it should be unnecessary?). What am I doing wrong, or is there an easier way to accomplish this?

• How can I upgrade my server's kernel without rebooting?

  - by Oli

  This is a loaded question because I'm already aware of, and am very interested in ksplice. The problem is that since they were bought by Oracle, they have been forced to pull numerous server distributions from the offerings. The answer isn't as simple as it once was. I noticed a question on Unix.SE that states: You can build your own ksplice patches to dynamically load into your own kernel Great! But how?! I've installed the free ksplice package in the repo on my desktop (not ksplice-uptrack which is non-free) and now want to generate and apply updates. What's the process? Are there any scripts out there to automate the process? Moreover, if all the machinery required for rebootless upgrades is sitting there in the kernel (and ksplice package), why on earth aren't we taking advantage of it by default? Note 1: I am happy for a solution beside ksplice but it has to deliver the same thing: rolling updates to the kernel that can be applied without rebooting the server. Note 2: I'll say it again; the main ksplice "service" does not support Ubuntu Server. It used to but it doesn't any more. When I talk about wanting to use ksplice, I'm talking about the open source tools in the ksplice package. Any answer that talks about ksplice-uptrack is probably not what I'm after as this is the part that integrates directly with aforementioned "service".

I have arranged the object in the scene as a list one below another Object1 Object2 Object3 When I click the Object1 --- should change to ObjectImage1 Object2 ----should change to ObjectImage2, but the above image of object1(objectImage1) at present should change to Object1 Object3 ----? should change to ObjectImage3,but the above image on object2(objectImage2) should change to Object2 These is similar to selection.I have coded Like when I click of Object2 its changing to ObjectIamge2 but the first object is not changing to object1 from objectImage1.Can anybody help me coding it out. Edit: public GameObject newSprite; private Vector3 currentSpritePosition; void Start() { newSprite.renderer.enabled = false; currentSpritePosition = transform.position; //then make it invisible renderer.enabled = false; //give the new sprite the position of the latter newSprite.transform.position = currentSpritePosition; //then make it visible newSprite.renderer.enabled = true; } void OnMouseExit(){ //just the reverse process renderer.enabled = true; newSprite.renderer.enabled = false; } This is the code used to change the material: public GameObject newSprite; private Vector3 currentSpritePosition; void Start(){ newSprite.renderer.enabled = false; } void OnMouseEnter(){ //getting the current position of the current sprite if ever it can move; currentSpritePosition = transform.position; //then make it invisible renderer.enabled = false; //give the new sprite the position of the latter newSprite.transform.position = currentSpritePosition; //then make it visible newSprite.renderer.enabled = true; } void OnMouseExit(){ //just the reverse process renderer.enabled = true; newSprite.renderer.enabled = false; }

• How to define type-specific scripts when using a 'type object' programming pattern?

  - by Erik

  I am in the process of creating a game engine written in C++, using the C/C++ SQLite interface to achieve a 'type object' pattern. The process is largely similar to what is outlined here (Thank you Bob Nystrom for the great resource!). I have a generally defined Entity class that when a new object is created, data is taken from a SQLite database and then is pushed back into a pointer vector, which is then iterated through, calling update() for each object. All the ints, floats, strings are loaded in fine, but the script() member of Entity is proving an issue. It's not much fun having a bunch of stationary objects laying around my gameworld. The only solutions I've come up with so far are: Create a monolithic EntityScript class with member functions encompassing all game AI and then calling the corresponding script when iterating through the Entity vector. (Not ideal) Create bindings between C++ and a scripting language. This would seem to get the job done, but it feels like implementing this (given the potential memory overhead) and learning a new language is overkill for a small team (2-3 people) that know the entirety of the existing game engine. Can you suggest any possible alternatives? My ideal situation would be that to add content to the game, one would simply add a script file to the appropriate directory and append the SQLite database with all the object data. All that is required is to have a variety of integers and floats passed between both the engine and the script file.

• My father is a doctor. He is insisting on writing a database to store non-critical patient information, with no programming background

  - by Dominic Bou-Samra

  So, my father is currently in the process of "hacking" together a database using FileMaker Pro, a GUI based databasing tool for his small (4 doctor) practice. The database will be used to help ease the burden on reporting from medical machines, streamlining quite a clumsy process. He's got no programming background, and seems to be doing everything in his power to not learn things correctly. He's got duplicate data types, no database-enforced relationships (foreign/primary key constraints) and a dozen other issues. He's doing it all by hand via GUI tool using Youtube videos. My issue is, that whilst I want him to succeed 100%, I don't think it's appropriate for him to be handling these types of decisions. How do I convince him that without some sort of education in these topics, a hacked together solution is a bad idea? He's can be quite stubborn and I think he sees these types of jobs as "childs play" How should I approach this? Is it even that bad an idea - or am I correct in thinking he should hire a proper DBA/developer to handle this so that it doesn't become a maintenance nightmare? NB: I am a developer consultant of 4 years and I've seen my share of painful customer implementations.

• Can't seem to install the correct version of PHP, using apt-get install

  - by Mark Tomlin

  I'm using Ubuntu 11.04 LTS server, it's a new install on a VPS box from MediaTemple (their ve server). I'm trying to install PHP 5.4.3 on this box, but I'm having a common problem not matter what version I get. I'm trying to get the php-cgi process, so I do the command apt-get install php-cgi and that installs, but does not provide me with the php-cgi executable. I need this so that I can run php-cgi -b 127.0.0.1:9000 and have it has a FastCGI process for my nginx install. Any idea what I can do to get this to work, bonus points if you can get this to work with PHP 5.4.3, because all I can seem to install is PHP 5.3.5.

• Restoring using SyncBack without profiles

  - by Thomas Matthews

  I backed up my internal hard drive (C:) using SyncBack onto an external (USB) hard drive with maximum compression. I then performed a clean install of Windows Vista onto the computer. I forgot to copy the SyncBack logs before the clean install. And now when ever I try to restore a directory, the RAR/ZIP files are copied to the system hard drive instead of extracting their contents to the hard drive. Also, SyncBack is not traversing the folders during the Restore process. How can I tell SyncBack to expand the compressed files? I am running the freeware version of SyncBack. I have to create new log files (unless SyncBack put them somewhere on the external drive). My alternative is to write a program that traverses the folders on the external drive and extracts files from the RAR/ZIP files. I am using Windows Vista, Service Pack 2, and the data size prior to backup was about 200 GB. (The backup process took over 72 hours due to "hiccups").

• Inconsistent booting problem 12.04LTS on Asus U46E RAL7

  - by G. He

  The laptop is dual booting with windows 7 and ubuntu 11.10. For 11.10 to boot, I had to add 'nolapic' in GRUB boot options. I downloaded 12.04LTS LiveCD yesterday and made a CD and a bootable USB stick. With both USB and LiveCD, occasionally I can boot into 12.04. But many times, the boot process stuck at some point. For USB boot, sometime it works. But other times, it seems to stuck right after seeing the message: NMI watchdog enabled. takes one hw-pmu counted [0.408590] #2 The number in [] changes. Some times it stuck at #2, and sometimes at #3. For LiveCD boot, sometime it works. But when it stuck, it stuck at different places. At times, the boot process go directly to a blank screen with a blink '_' at up left corner. Sometime it went a bit further, after showing options to try/install ubuntu then stuck with a blank screen with blink '_'. Anything I can do to get around of this?

The command I'm currently thinking of is tcpdump -i iface -n -t -q. Is it guaranteed that tcpdump will process all packets? What happens if the CPU is working to full capacity? The format of the output lines is IP ddd.ddd.ddd.ddd.port > ddd.ddd.ddd.ddd.port: tcp 1260. What exactly is 1260? I have the suspicion that it is the payload in bytes of the packet, which would be exactly what I need, but I'm not sure. It might be the TCP Window Size. Or perhaps there is an even better way of doing this? I thought about a LOG rule in iptables, but tcpdump seems easier and I don't know whether iptables can log the packet lengths.

• Can you say "Architect?"

  - by Bob Rhubart

  Photo by Jennifer Ortiz In his article, It's Time To Occupy IT, AIIM CEO and president John Mancini examines the evolution of "Systems of Engagement," the social technologies that are transforming how customers and employees relate to and interact with companies. Surviving the disruption that transformation entails is a matter of when, rather than if, a given organization embraces the change. But as Mancini points out, that transformation will require a "new breed" of IT professional: "While addressing this kind of challenge requires technical skills, it also requires process and customer acumen more often found in the business than in our IT departments. It requires a new type of information professional, whose expertise includes technical and domain knowledge, but who also has an idea of how the pieces of a process that spans the worlds of Systems of Record and Systems of Engagement should fit together. Gartner estimates that the demand for this new breed of information professional will grow by 50 percent by 2015." Though Mancini makes no reference to the title, the skills he desribes are those of the IT architect. While the specific definition of the role remains fodder for seemingly endless discussion and debate on various social networks and forums, the fact remains that the skills required for success in the evolving world of IT will increasingly involve a deep understanding of how all the pieces fit together.

• Visual Studio 2010 editor painfully slow

  - by Daniel Gehriger

  I'm running out of patience with MS VisualStudio 2010: I'm working on a solution containing ~50 C++ projects. When using the editor, I experience a lag of 1 - 2 seconds whenever I move the cursor to a different line, or when I move to a different window, or generally when the editor losses and gains focus. I went through a whole series of optimizations, to no avail: installed all hotfixes for VS2010 disabled all add-ins and extensions disabled Intellisense deleted all temporary files created by VS2010 disabled hardware acceleration unloaded all but 15 projects disabled tracking changes closed all but one window and so on. This is on a Dual Core machine with SSD harddrive (verified throughput 100MB/s), enough free space on HD, Windows 7 Pro 32-bit with 3GB of RAM and most of it still free. Whenever I type a letter, CPU usage of devenv.exe goes to 50 - 90% in process monitor for 1 - 2 seconds before returning to 5%. I used Process Explorer to analyze registry and file system access, and I only notice frequent accesses to the .sln file (which is quiet small), and a few registry reads, but nothing that would raise a red flag. I don't have this problem with solutions containing less projects, so I'm inclined to think that it's related to the number of projects. For your information, the entire solution has been migrated over the years from VS2005 to VS2008 to now VS2010. Does anyone have any ideas what else I could do to resume work on this project, other than returning to VS2008?

• Release/Change management - best aproach

  - by Bob Rivers

  I asked this question an year ago in StackOverflow and never got a good answer. Since Programmers seems to be a better place to ask it, I'll give it a try... What is the better way to work with release management? More specifically what would be the best way to release packages? For example, assuming that you have a relatively stable system, a good quality assurance process (QA), etc. How do you prefer to release new versions? Let's assume that we are talking about a mid to large "centralized" web system (no clients), in-house development. This system can be considered "vital" for a corporate operations. I have a tendency to prefer to do this by releasing packets at regular intervals, not greater than 1 to 3 months. During this period, I will include into the package,fixes and improvements and make the implementation in production environment only once. But I've seen some people who prefer to place small changes in production, but with a greater frequency. The claim of these people is that by doing so, it is easier to identify bugs that have gone through the process of QA: in a package with 10 changes and another with only 1, it is much easier to know what caused the problem in the package with just one change... What is the opinion came from you?

• Trouble installing Ubuntu 12.04 from USB

  - by Kyle J

  I want to dual-boot Ubuntu Desktop 12.04 on my new ultrabook which has an Intel i7 3517U processor 6GB RAM Windows 7, 64-bit no CD/DVD drive I created my bootable USB stick using pendrivelinux.com with the "ubuntu-12.04.1-desktop-i386.iso". I am following these directions because they include nice screenshots; however, I do not get very far in the process. I am able to boot into the Live Desktop, and then I try to install onto my hard disk. Here are the series of actions that I take next: First, I see this ( http://i.imgur.com/vucYH ) window, and click 'continue' Then I get this ( http://imgur.com/2wESc ) window, and click 'continue' again This appears: and I get worried because it seems like there is no recognition that I have Windows installed. According to the directions I am following, I should see /dev/sda1 and /dev/sda2 partitions. In the drop-down menu at the bottom the only "Device for boot loader installation" is /dev/sdb and no information is shown. I am hesitant to click 'Install Now' for fear of what it might do to Windows. 4. I click 'Quit' and cancel the installation, but then about 5 seconds later this ( http://imgur.com/a/yXi0C ) window pops up (I have expanded it to full screen to scroll and show all the details). 5. Another second later this ( http://imgur.com/vxcrN ) comes up. I'm not sure how relevant this is. Does anyone have any insight into this issue?? Why does it not show my current Windows partition? What would happen if I tried to continue with the installation process? Thanks! PS - sorry, it would only let me post 2 hyperlinks as a new user

• Why is my root filesystem always scanned at boot?

  - by luri

  I always have a pause at boot saying my filesystems are being checked (with a "press C to cancel" note, too). Actually (seeing boot.log) I think it's the / fs, which is located at /dev/sdb5 Several questions altoghether, here (hope this does not break any rule): Is this normal? Can I (or even should I) prevent this anyhow? According to boot.log (below) the fs does not seem to be 'clean', or, at least, it's in an state or condition that makes fsck always can it for errors for a while (just a few seconds). How can I fix it? Edit: This is my boot.log: fsck desde util-linux-ng 2.17.2 udevd[515]: can not read '/etc/udev/rules.d/z80_user.rules' /dev/sdb5: 249045/32841728 ficheros (0.3% no contiguos), 20488485/131338752 bloques init: ureadahead-other main process (1111) terminated with status 4 init: ureadahead-other main process (1116) terminated with status 4 Password: * Starting AppArmor profiles [160G Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox [154G[ OK ] * Setting sensors limits [160G [154G[ OK ] And this is dumpe2fs results for the filesystem being checked (well, the relevant part of the log): Filesystem volume name: <none> Last mounted on: / Filesystem UUID: 42509bf9-f3e6-460a-8947-ec0f5c1fbcc8 Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize Filesystem flags: signed_directory_hash Default mount options: (none) Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 32841728 Block count: 131338752 Reserved block count: 6566937 Free blocks: 110850356 Free inodes: 32592701 First block: 0 Block size: 4096 Fragment size: 4096 Reserved GDT blocks: 992 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 8192 Inode blocks per group: 512 Flex block group size: 16 Filesystem created: Fri Dec 10 19:44:15 2010 Last mount time: Mon Feb 14 17:00:02 2011 Last write time: Mon Feb 14 16:59:45 2011 Mount count: 1 Maximum mount count: 33 Last checked: Mon Feb 14 16:59:45 2011 Check interval: 15552000 (6 months) Next check after: Sat Aug 13 17:59:45 2011 Lifetime writes: 331 GB Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 256 Required extra isize: 28 Desired extra isize: 28 Journal inode: 8 First orphan inode: 28049496 Default directory hash: half_md4 Directory Hash Seed: d3d24459-514b-4413-b840-e970b766095b Journal backup: inode blocks Journal features: journal_incompat_revoke Tamaño de fichero de transacciones: 128M Journal length: 32768 Journal sequence: 0x0005e0c4 Journal start: 1 This is the relevant (at least I think this is the fs being checked) line in fstab: #Entry for /dev/sdb5 : UUID=42509bf9-f3e6-460a-8947-ec0f5c1fbcc8 / ext4 errors=remount-ro 0 1

• MySQL taking a long time to start

  - by Dscoduc

  I'm running Windows Server 2008 with MySQL installed and every time I reboot the server the MySQL Service doesn't start right away. A look into the Windows Eventlog shows that the MySQL Service was hung at startup. Looking at the Services.msc console shows the service state at Starting... Eventually, like 10 minutes, the MySQL Service actually finishes the startup process and the database becomes available for my Wordpress server... I looked at the MySQL .err files and didn't find anything that would indicate a delay in the statup process... Can anyone suggest a way to determine what is causing the delay, and more importantly, how to prevent the delay in the MySQL Startup?
