• Why does Apache ignore my Directory block?

  - by Codemonkey

  I just moved my projects into a new workstation. I'm having trouble getting my Apache installation to acknowledge my .htaccess files. This is my /etc/apache2/conf.d/dev config file: <Directory /home/codemonkey/dev/myproject/> Options -Indexes AllowOverride All Order Allow,Deny Deny from all </Directory> I know the config file is being included by Apache because it complains if I put erroneous syntax in it (Action 'configtest' fails). My project is reachable through Apache by a symlink in the /var/www directory. The server is running with my user and group, so it has my permissions. My entire dev folder has permissions set to 770 recursively. Despite all this, I'm still getting an indexed display of my project folder when I visit http://localhost/myproject. Why isn't the above config making it impossible to view the folder in the browser?

• Eris Update to 2.1 &ndash; No Problems

  - by Bunch

  I updated my Eris to Android’s 2.1 OS last night and everything went pretty well. I had wanted to update the phone mainly for two reasons. The first was to have the Navigation feature of the Google Maps application and to make YouTube work again. YouTube used to work on the phone and then stopped a few weeks ago. But before I started I looked around various forums and blogs to see what doom and gloom folks were talking about the update. Based on what I read and some common sense I used the following steps: Made sure there was a good charge on the phone. Connected to our WiFi (the download is about 77 megs, not very 3G friendly). Checked that the contacts were synced with the GMail account. As a precaution I copied off any music and pictures from the SD card to my laptop. Started the update process and waited for the download and installation to complete. It took maybe 30 minutes to do everything. After the update I re-synced the contacts and tested out the phone (it does make calls after all). I did need to download the text to speech application to get the Maps Navigation to work but that was easy enough since the application prompted me to download it. And now the YouTube application works again. Technorati Tags: Android

• 403 forbidden error from cron

  - by user112570

  I have some php code that runs fine in a browser but now I want to use the same code and execute it from a cron script I'm getting issues. i tried the command on cron wget -O /dev/null http://www.mydomain.com/test.php but if i try that in the terminal i get the error below. What is the correct command to run a php file from cron? and do I need to add extra line of code to the top of my php file? The problem I'm getting is -bash-3.2$ wget -O /dev/null http://www.mydomain.com/test.php --2012-04-08 15:59:41-- http://www.mydomain.com/test.php Resolving www.mydomain.com... 46.***.***.1 Connecting to www.mydomain.com|46.***.***.1|:80... connected.

• Effective handling of variables in non-object oriented programming

  - by srnka

  What is the best method to use and share variables between functions in non object-oriented program languages? Let's say that I use 10 parameters from DB, ID and 9 other values linked to it. I need to work with all 10 parameters in many functions. I can do it next ways: 1. call functions only with using ID and in every function get the other parameters from DB. Advantage: local variables are clear visible, there is only one input parameter to function Disadvantage: it's slow and there are the same rows for getting parameters in every function, which makes function longer and not so clear 2. call functions with all 10 parameters Advantage: working with local variables, clear function code Disadvantage: many input parameters, what is not nice 3. getting parameters as global variables once and using them everywhere Advantage - clearer code, shorter functions, faster processing Disadvantage - global variables - loosing control of them, possibility of unwanted overwriting (Especially when some functions should change their values) Maybe there is some another way how to implement this and make program cleaner and more effective. Can you say which way is the best for solving this issue?

• Commands don't have permission when using absplute path

  - by Markos

  I have folders set up this way: /srv/samba/video getfacl /srv/samba/video # file: srv/samba/video # owner: root # group: nogroup user::rwx group::--- group:sambaclients:rwx group:deluge:rwx mask::rwx other::--- default:user::rwx default:group::--- default:group:sambaclients:rwx default:group:deluge:rwx default:mask::rwx default:other::--- That means, user deluge has rwx to folder /srv/samba/video. However, when running command as user deluge, I am getting weird permission errors. When in folder /srv/samba/video: sudo -u deluge mkdir foo works flawlessly. But when using absolute path: sudo -u deluge mkdir /srv/samba/video/foo I am getting permission denied. When running sudo -u deluge id, I get output uid=113(deluge) gid=124(deluge) skupiny=124(deluge) which shows that user deluge is indeed in group deluge. Also, the behavior was the same when I gave the permissions also to user deluge not just group deluge. When executing as non-system user, it does work. The reason that I want to use absolute paths is that I am using automatically triggered post-download script which extracts some files into the folder. I have spent way too many hours to solve this problem myself. mkdir isn't the only command that fails, touch is doing the same thing, so I suspect that it's not mkdir's fault. If you need more info, I will try to put it in here, just ask. Thanx in advance.

• Forgot password to development database

  - by ninja08

  I've created a database using terminal while following along with a tutorial. Although I had a lot of trouble getting the databases to install. Now after finally getting it to work I changed a few things, actually just the name of the database using the rake command to just "next". The password should be 'secret password'. How can I change the password or find out what it is or change it? It doesn't seem to be edited my databases.yml file with the password, especially since it still just says 'root' as username with now password in there.

• Dojo and Separate JavaScript File

  - by Bunch

  For a project I needed to use the ArcGIS API for some mapping. To use this you need to use Dojo but in this case all it really comes down to is adding some require lines and a addOnLoad on your web page. At first everything was working great, the maps rendered and the various layers would populate as needed. Once it was working I started moving the various javascript functions into their own files to keep everything nice and neat. Then the problems started, mainly the map would not show up any more. So that was a pretty big problem. Luckily the fix was pretty simple, just move the dojo.addOnLoad line into it’s own script tag. If I had the dojo.addOnLoad in the same script block as the various require lines it would not work as expected. Works: <script type="text/javascript" language="javascript" src="javascript/test.js" />     <script type="text/javascript">       dojo.require("esri.map");       dojo.require("esri.tasks.locator");       dojo.require("esri.tasks.query");       dojo.require("esri.tasks.geometry");  </script>  <script type="text/javascript">      dojo.addOnLoad(init);  </script> Does not work: <script type="text/javascript" language="javascript" src="javascript/test.js" /> <script type="text/javascript">       dojo.require("esri.map");       dojo.require("esri.tasks.locator");       dojo.require("esri.tasks.query");       dojo.require("esri.tasks.geometry");       dojo.addOnLoad(init); </script> Technorati Tags: JavaScript,Dojo

• andEngine dynamic sprites

  - by Blucreation

  Ive just started with andEngine the past week and i only started learning java/android 3 weeks. I can use a for loop to add multiple sprites to the screen but when i try to check collisions on them it only does it to one and not the rest. I want to be able to add a specific number for sprites made from the same texture to the scene, add collision detection to them and also make them slide across the screen (im making a game where you avoid the obstacles). My simple code: private void createobstacle(float pX, float pY) { obstacle = new AnimatedSprite(pX, pY, this.mObjTextureRegion.deepCopy(), getVertexBufferObjectManager()); obstacle.setScale(MathUtils.random(0.5f, 3f)); scene.attachChild(obstacle); } private void createobstacle(int num) { for(int i=0; i<=num; i++ ) { final float xPos = MathUtils.random(30.0f, (CAMERA_WIDTH - 30.0f)); final float yPos = MathUtils.random(30.0f, (CAMERA_HEIGHT - 30.0f)); createobstacle(xPos, yPos); } } Ive read about arrays but i cannot find any tutorials about anything im stuck with. Any help would be great!

• Making python run on my webserver

  - by richzilla

  Hi all, im getting a bit stuck regarding options for running python scripts on my server. From the research ive done so far, i can see i need to modify apache slightly to run python scripts, by using either mod_wsgi or mod_python. Two issues i have: mod_python doesnt appear to be maintained anymore (last release, 2007) mod_wsgi appears to require modification of my httpd.conf file on a per application basis. What im wanting to know, is there a way of getting python scripts to run in the same way as php, i.e. just by going to index.py etc... or is it more involved than that? At present im just trying to set it up on my xampp install. Any help would be appreciated.

• PASS: Budget Status

  - by Bill Graziano

  Our budget situation is a little different this year than in years past.  We were late getting an initial budget approved.  There are a number of different reasons this occurred.  We had different competing priorities and the budget got pushed down the list.  And that’s completely my fault for not making the budget a higher priority and getting it completed on time. That left us with initial budget approval in early August rather than prior to June 30th.  Even after that there were a number of small adjustments that needed to be made.  And one large glaring mistake that needed to be fixed.  We had a typo in the budget that made it through twelve versions of review.  In my defense I can only say that the cell was red so of course it had to be negative!  And that’s one more mistake I can add to my long and growing list of Mistakes I’ll Never Make Again. Last week we passed a revised budget (version 17) with this corrected.  This is the version we’re cleaning up and posting to the web site this week or next.

• Pandaboard crash on startup or freeze after minutes

  - by Meach

  I just received my Pandaboard ES (rev B) and I am having trouble after installing ubuntu-omap4-addons. Once I copied the image ubuntu-12.04-preinstalled-desktop-armhf+omap4.img on my sd card and boot the pandaboard with it, I run the following commands: sudo add-apt-repository ppa:tiomap-dev/release sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install ubuntu-omap4-extras At the end of the installation of ubuntu-omap4-extras, Ubuntu tells me that a problem occurs when the console displays: ldconfig deferred processing now taking place Clicking on "report the problem" tell me that the problem concerns pvr-omap4-dkms. I read somewhere that this can happen and it is better to reinstall pvr-omap4-dkms. Which I am doing by running: sudo apt-get install --reinstall pvr-omap4-dkms I reboot. Then the board has sometimes difficulties to start Ubuntu: it freezes during the loading page, only action I can do is unplugging the board to start it again. Some other times, Ubuntu load successfully but then freeze at another random time, in the range 20 - 40 minutes. I searched on internet for similar bug and found this: https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4/+bug/971091 So I typed this in: update-rc.d ondemand disable apt-get -y install cpufrequtils echo 'ENABLE="true" GOVERNOR="performance" MAX_SPEED="0" MIN_SPEED="0"' > /etc/default/cpufrequtils cpufreq-set -r -g performance reboot But it doesn't seems to fix the bug. Another detail: on startup, before the loading screen of Ubuntu (when there is the two penguins displayed :)), it shows this: [0.297271] CPU1: Unknown IPI message 0x1 [0.308990] omap_hwmod: mcpdm: _wait_target_ready error: -16 [0.354705] omap_mux_get_by_name: Could not find signal uart1_cts.uart1_cts [0.354766] omap_hwmod_mux_init: Could not allocate device mux entry [2.107086] thermal_get_slope:Getting slope is not supported for domain gpu [2.107116] thermal_get_offset:Getting offset is not supported for domain gpu [2.107299] stm_fw: vendor driver stm_ti1.0 registered [8.725555] OMAPRPC: Registration of OMAPRPC rpmsg service returned 0! debug=0 Any idea what can be wrong? I am not that good with Ubuntu so any help will be appreciated. Cheers! Meach

• Using Clojure instead of Python for scalability (multi core) reasons, good idea?

  - by Vandell

  After reading http://clojure.org/rationale and other performance comparisons between Clojure and many languages, I started to think that apart from ease of use, I shouldn't be coding in Python anymore, but in Clojure instead. Actually, I began to fill irresponsisble for not learning clojure seeing it's benefits. Does it make sense? Can't I make really efficient use of all cores using a more imperative language like Python, than a lisp dialect or other functional language? It seems that all the benefits of it come from using immutable data, can't I do just that in Python and have all the benefits? I once started to learn some Common Lisp, read and done almost all exercices from a book I borrowod from my university library (I found it to be pretty good, despite it's low popularity on Amazon). But, after a while, I got myself struggling to much to do some simple things. I think there's somethings that are more imperative in their nature, that makes it difficult to model those thins in a functional way, I guess. The thing is, is Python as powerful as Clojure for building applications that takes advantages of this new multi core future? Note that I don't think that using semaphores, lock mechanisms or other similar concurrency mechanism are good alternatives to Clojure 'automatic' parallelization.

• How do I log which process is deleting a file on Windows XP?

  - by Jordan Milne

  I'm having an issue with a file getting deleted seemingly randomly throughout the day. The vendor of the software whose file is getting deleete says that another piece of software installed on the computer is deleting it, while the other software's vendor says the opposite. I've tried using Process Monitor so I can pinpoint exactly what's deleting it, but even when filtered specifically to that file, createfile operations are being triggered a few times a second, and I can't seem to filter it to deletions specifically. Is there a tool or script I can use to specifically monitor deletion attempts on a single file?

• How do I negotiate for colo space?

  - by randy melder

  I guess this isn't a technical question, but it definitely is something IT teams deal with, so here goes: I'm looking at getting a rack at a local colocation facility. I'm weighing the options versus building out in a cloud platform. We are REALLY low bandwidth and power. There's a total of six hosts for the total operation. You can assume we use <= 10 amps of power and <= 2Mbps 95th percentile. Do you have any advice for getting the best deal?

• SQL Server Database Settings

  - by rbishop

  For those using Data Relationship Management on Oracle DB this does not apply, but for those using Microsoft SQL Server it is highly recommended that you run with Snapshot Isolation Mode. The Data Governance module will not function correctly without this mode enabled. All new Data Relationship Management repositories are created with this mode enabled by default. This mode makes SQL Server (2005+) behave more like Oracle DB where readers simply see older versions of rows while a write is in progress, instead of readers being blocked by locks while a write takes place. Many common sources of deadlocks are eliminated. For example, if one user starts a 5 minute transaction updating half the rows in a table, without snapshot isolation everyone else reading the table will be blocked waiting. With snapshot isolation, they will see the rows as they were before the write transaction started. Conversely, if the readers had started first, the writer won't be stuck waiting for them to finish reading... the writes can begin immediately without affecting the current transactions. To make this change, make sure no one is using the target database (eg: put it into single-user mode), then run these commands: ALTER DATABASE [DB] SET ALLOW_SNAPSHOT_ISOLATION ONALTER DATABASE [DB] SET READ_COMMITTED_SNAPSHOT ON Please make sure you coordinate with your DBA team to ensure tempdb is appropriately setup to support snapshot isolation mode, as the extra row versions are stored in tempdb until the transactions are committed. Let me take this opportunity to extremely strongly highly recommend that you use solid state storage for your databases with appropriate iSCSI, FiberChannel, or SAN bandwidth. The performance gains are significant and there is no excuse for not using 100% solid state storage in 2013. Actually unless you need to store petabytes of archival data, there is no excuse for using hard drives in any systems, whether laptops, desktops, application servers, or database servers. The productivity benefits alone are tremendous, not to mention power consumption, heat, etc.

• Open Source Projects for Beginning Coders?

  - by MattDMo

  After working as a molecular biologist at the bench for many years, I lost my job last year and am thinking about a career change. I've been using open-source software and doing Linux system administration since the mid 90s, and have written/improved some small shell/Perl/PHP scripts, and am very comfortable building from source, but never progressed to creating non-trivial programs de novo. I want to move to actually learning real programming skills and contributing back to the community, with the possible eventual goal of getting into bioinformatics as a career in the future. I'm a stay-at-home dad now, so I have some time on my hands. I've done a lot of research on languages, and have settled on Python as my major focus for now. I'm set up on GitHub, but haven't forked anything yet. I've looked around OpenHatch some, but nothing really grabbed me. I've heard the advice to work on what you use/love, but that category is so broad that I'm having trouble finding any one thing to get started on. What are your suggestions for getting started? How do you pick a project that will welcome your (possibly amateurish) help? With a fairly limited skill set, how do you find a request that you can handle? What are common newbie mistakes to avoid? Any other advice?

• Tumblr custom domain not redirecting properly

  - by Manic

  I decided to host my blog at Tumblr, using their custom domain setup (http://blog.smokingfishgames.com/ instead of http://smokingfishgames.tumblr.com). However, it's been 72 hours and I'm still getting spotty redirection. It works some of the time--I go and see the page and blog, and it's all fine. However, it occasionally just stops working and redirects back to my web host, which is a directory with nothing but a single file called BUGGER.html (which I stuck in to make sure that it was my web host and not some Tumblr empty directory). Clearing the Chrome DNS cache makes the problem go away--for a while. After a few minutes, or an hour, or however long, I'll start seeing BUGGER.html again. I clear the cache, and poof, the blog shows up. The thing that's curious to me is that when I clear the cache and get BUGGER.html again (which happens occasionally), I can look at my Chrome DNS cache and see assets.tumblr.com UNSPECIFIED blog.smokingfishgames.com UNSPECIFIED www.tumblr.com UNSPECIFIED IP addresses and expiration times omitted for brevity's sake--if they're important I'm sure I can replicate the issue. This implies, to me anyway, that my browser is reaching Tumblr but getting bounced back to my web host. Any reason why this would be happening, or is this a normal symptom of DNS propagation? If it is a problem, should I be bothering Tumblr or my host with it, or is this something I can fix myself?

• Very fast Laptop Heating due to very high CPU usage by dwm.exe

  - by Sushan Shrestha

  My laptop gets heated very fast and when I check the task manager, I find dwm.exe consuming very high CPU (mostly 100%). In the beginning I found the message "The graphic adapter has been stopped and recovered".Also I am getting one error message "Cidaemon.exe has stopped working" very frequently. During this period also, cpu usage is 100% which is consumed by dwm.exe. I have run ccleaner and Kingsoft PC doctor monitor to fix the register problem but the problem has not been solved. My display adaptor is : NVIDIA NVS 5200M. After the driver update, I am not getting "The graphic adapter has been stopped and recovered" but dwm.exe is still consuming 100% CPU one time in about 5 mins. Multiple restarts has not helped. Laptop Model: Dell Latitude E6430. Thanks in advance.

• A design for watching IPTV anywhere in the house?

  - by Carlos

  I'm currently getting TV and internet via IP to my house. The service comes into an ISP-supplied Router (ST585) which is in turn connected to an IPTV box. I need to replace the router, as it's port forwarding seems to be broken, so I was thinking of getting a box with an IGMP proxy. I once mistakenly got a non-IGMP box, with the result that the internet worked, but the IPTV didn't. The trouble is, I have no idea how to set up the IPTV part of the installation. I do have a copy of the ST585 configuration, but it doesn't look anything like the Cisco stuff that I learned about at CCNA. What are the steps necessary to reproduce the IGMP setup? I was thinking of WireSharking the communications on the network, but I suppose I'd need a hub for that? As a bonus, since the packets are coming in with the TV signal, is it possible to mess with the IGMP setup so I can watch TV anywhere in the house?

• Network connection fails when downloading data

  - by Guus

  In the past few weeks, I've noticed my network connection becoming unstable while downloading files. I'm not sure how to diagnose this issue. I've found that my network connections appear to be temporarily unresponsive (for periods up to a minute or so) while I'm downloading a file (that's large enough to not be downloaded instantly). The problem occurs when downloading data through a webbrowser, but also when using SCP to download data from a remote location. During the period in which network connections are unresponsive, every resource that I try to access over the network is unavailable. This includes: The download itself (SCP reports a 'stalled' download) Web pages (won't load - browsers report 'resource unavailable') SSH sessions (CLI freezes) VPN connections (connections terminate) IM client connections (client starts reconnection attempts) ... (everything is pretty much dead) I've noticed that during such a period, I cannot even access the (web-based) administrative console of the router on my LAN at home (although it remains reachable for other devices). The problem occurs when connected to my home network, but also when I'm in the office. Other devices than my laptop are not affected. Given the above two characteristics I assume the problem cause lies within my laptop, not the network infrastructure. I'm running Ubuntu 11.10. Apart from applying automatic updates from Ubuntu, I can't think of a change that I applied to the OS that could have started the problems. I'm absolutely positive that this issue did not occur up to a few weeks ago (as it's very noticeable, and only started to annoy me in the last few days). When the problem occurs, applications that make use of a network connection fail visibly (I get popups telling me that a VPN connection is broken, for instance). The network manager does not report any issues related to my wifi-connection though. Help?
