• Monitoring Database disk space

  - by Michael Freidgeim

  An article Data files: To Autogrow Or Not To Autogrow? recommends NOT to rely on auto-grow, because it causing delays in unplanned times.We should mtonitor database files(both data and log), and if they close to max capacity, manually increase the size. However it doesn't give references, how to monitor the free space inside databases. I've tried to look how to do it. It can be done manually using   execute sp_spaceused for the database in question or  sp_SOS (can be downloaded from http://searchsqlserver.techtarget.com/tip/Find-size-of-SQL-Server-tables-and-other-objects-with-stored-procedure)Alternatively you can run SQL commands as suggested in Http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=82359 by Michael Valentine Jonesselect [FREE_SPACE_MB] = convert(decimal(12,2),round((a.size-fileproperty(a.name,'SpaceUsed'))/128.000,2)) from dbo.sysfiles aMore useful article Monitor database file sizes with SQL Server Jobs describes how to setup monitoring Finally I found the excellent articleManaging Database Data Usage With Custom Space Alerts, that can be followed even support personnel without much DBA experience.

• Why is my external USB hard drive sometimes completely inaccessible?

  - by Eliah Kagan

  I have an external USB hard drive, consisting of an 1 TB SATA drive in a Rosewill RX35-AT-SU SLV Aluminum 3.5" Silver USB 2.0 External Enclosure, plugged into my SONY VAIO VGN-NS310F laptop. It is plugged directly into the computer (not through a hub). The drive inside the enclosure is a 7200 rpm Western Digital, but I don't remember the exact model. I can remove the drive from the enclosure (again), if people think it's necessary to know that detail. The drive is formatted ext4. I mount it dynamically with udisks on my Lubuntu 11.10 system, usually automatically via PCManFM. (I have had Lubuntu 12.04 on this machine, and experienced all this same behavior with that too.) Every once in a while--once or twice a day--it becomes inaccessible, and difficult to unmount. Attempting to unmount it with sudo umount ... gives an error message saying the drive is in use and suggesting fuser and lsof to find out what is using it. Killing processes found to be using the drive with fuser and lsof is sometimes sufficient to let me unmount it, but usually isn't. Once the drive is unmounted or the machine is rebooted, the drive will not mount. Plugging in the drive and turning it on registers nothing on the computer. dmesg is unchanged. The drive's access light usually blinks vigorously, as though the drive is being accessed constantly. Then eventually, after I keep the drive off for a while (half an hour), I am able to mount it again. While the drive doesn't work on this machine for a while, it will work immediately on another machine running the same version of Ubuntu. Sometimes bringing it back over from the other machine seems to "fix" it. Sometimes it doesn't. The drive doesn't always stop being accessible while mounted, before becoming unmountable. Sometimes it works fine, I turn off the computer, I turn the computer back on, and I cannot mount the drive. Currently this is the only drive with which I have this problem, but I've had problems that I think are the same as this, with different drives, on different Ubuntu machines. This laptop has another external USB drive plugged into it regularly, which doesn't have this problem. Unplugging that drive before plugging in the "problem" drive doesn't fix the problem. I've opened the drive up and made sure the connections were tight in the past, and that didn't seem to help (any more than waiting the same amount of time that it took to open and close the drive, before attempting to remount it). Does anyone have any ideas about what could be causing this, what troubleshooting steps I should perform, and/or how I could fix this problem altogether? Update: I tried replacing the USB data cable (from the enclosure to the laptop), as Merlin suggested. I should've tried that long ago, since it fits the symptoms perfectly (the drive works on another machine, which would make sense because the cable would be bent at a different angle, possibly completing a circuit of frayed wires). Unfortunately, though, this did not help--I have the same problem with the new cable. I'll try to provide additional detailed information about the drive inside the enclosure, next time I'm able to get the drive working. (At the moment I don't have another machine available to attach it.) Major Update (28 June 2012) The drive seems to have deteriorated considerably. I think this is so, because I've attached it to another machine and gotten lots of errors about invalid characters, when copying files from it. I am less interested in recovering data from the drive than I am in figuring out what is wrong with it. I specifically want to figure out if the problem is the drive or the enclosure. Now, when I plug the drive into the original machine where I was having the problems, it still doesn't appear (including with sudo fdisk -l), but it is recognized by the kernel and messages are added to dmesg. Most of the message consist of errors like this, repeated many times: [ 7.707593] sd 5:0:0:0: [sdc] Unhandled sense code [ 7.707599] sd 5:0:0:0: [sdc] Result: hostbyte=invalid driverbyte=DRIVER_SENSE [ 7.707606] sd 5:0:0:0: [sdc] Sense Key : Medium Error [current] [ 7.707614] sd 5:0:0:0: [sdc] Add. Sense: Unrecovered read error [ 7.707621] sd 5:0:0:0: [sdc] CDB: Read(10): 28 00 00 00 00 00 00 00 08 00 [ 7.707636] end_request: critical target error, dev sdc, sector 0 [ 7.707641] Buffer I/O error on device sdc, logical block 0 Here are all the lines from dmesg starting with when the drive is recognized. Please note that: I'm back to running Lubuntu 12.04 on this machine (and perhaps that's a factor in better error messages). Now that the drive has been plugged into another machine and back into this one, and also now that this machine is back to running 12.04, the drive's access light doesn't blink as I had described. Looking at the drive, it would appear as though it is working normally, with low or no access. This behavior (the errors) occurs when rebooting the machine with the drive plugged in, and also when manually plugging in the drive. A few of the messages are about /dev/sdb. That drive is working fine. The bad drive is /dev/sdc. I just didn't want to edit anything out from the middle.

• What's the standard location of a 3D clipping box?

  - by Kendall Frey

  The way I understand 3D rendering, polygons are transformed using several matrices, and they are then clipped if they are not inside a certain box, before projecting the box onto the screen. Before transformation, the visible area is typically a frustum, and after transformation, I am guessing it's a cube. This cube makes the clipping math easier than a frustum would. My question is, what's the 'standard' location/size for this clipping box? I can think of 3 possibilities: (0,0,0)-(1,1,1), (-0.5,-0.5,-0.5)-(0.5,0.5,0.5), (-1,-1,-1)-(1,1,1) Or is there no standard?

• 3D collision detection with meshes using only raycasting?

  - by Nick

  I'm building a game using WebGL and Three.js, and so far I have a terrain with a guy walking on it. I simply cast a ray downwards to know the terrain height. How can I do this for other 3D objects, like the inside of a house? Is this possible by casting many rays in every direction of the player? If not, I would like to know how I can achieve the simplest collision detection possible for other meshes. Do you have to cast a ray to every triangle in every mesh nearby?

• Are CQRS/DDD/Event Sourcing and REST compatible?

  - by Robin Green

  REST seems to promote the idea of a canonical URL for a resource, and PUTing/POSTing back a modified representation of that resource in order to change it. However, with CQRS - Command Query Responsibility Segregation - one can theoretically have a completely different "API" for reading and for writing, which seems to conflict with the REST ideal of one URL for a resource, and no RPC-style "verbs inside the request body". DDD and Event Sourcing sometimes go together with CQRS, which is why I mention them in this question. So, can CQRS be used together with REST? Or is it against the REST way of doing things? What about DDD? And Event Sourcing? Can they be used with REST?

• Returning a mock object from a mock object

  - by Songo

  I'm trying to return an object when mocking a parser class. This is the test code using PHPUnit 3.7 //set up the result object that I want to be returned from the call to parse method $parserResult= new ParserResult(); $parserResult->setSegment('some string'); //set up the stub Parser object $stubParser=$this->getMock('Parser'); $stubParser->expects($this->any()) ->method('parse') ->will($this->returnValue($parserResult)); //injecting the stub to my client class $fileHeaderParser= new FileWriter($stubParser); $output=$fileParser->writeStringToFile(); Inside my writeStringToFile() method I'm using $parserResult like this: writeStringToFile(){ //Some code... $parserResult=$parser->parse(); $segment=$parserResult->getSegment();//that's why I set the segment in the test. } Should I mock ParserResult in the first place, so that the mock returns a mock? Is it good design for mocks to return mocks? Is there a better approach to do this all?!

• remove failed ubuntu installation

  - by kapitanluffy

  i tried installing ubuntu alongside windows 7 Installing Ubuntu alongside Windows and i failed so i decided to go with wubi again. after installing it, i noticed a separate hard disk. i investigated and found out that this hard disk is actually for the failed installation. i don't know where to find it inside the windows system. can anyone please teach me how to remove the 'failed' hard disk. here's a screenshot the left side is the current filesystem. the right side on the other hand is the 'failed' harddisk. i verified that it is the failed one because the wubi installation will provide a 'host' folder for the current partition it is currently installed. i tried looking for the 'failed' one using the windows' commandline but i don't know where to look for the 'failed' disk. (i used the cmd coz i don't want root.disk to mysteriously disappear again.) see http://ubuntu-with-wubi.blogspot.com/2011/01/mystery-of-disappearing-rootdisk.html

• Why Is ModSecurity Unable to Access the Data Directory?

  - by tommytwoeyes

  Update I think we've solved this; the problem appears to have been a result of the /modsec_storage directory having an incorrect value for its SELinux context type. However, we're still not sure, because although after I changed the SELinux context type value, Apache was able to create files in that directory for the global and ip collections (global.dir/global.pag and ip.dir/ip.pag), the new files still have zero bytes. I'm new to ModSecurity and am not sure if the files are empty because something is wrong with the configuration or if ModSecurity has simply determined it doesn't need to store IP addresses persistently after each transaction ends. Anyone able to offer guidance here? I've recently installed ModSecurity (v2.5.12 / CRS v2.0.8) on our production server, and everything works great, except for these errors that it keeps writing to the Apache error log: Failed to access DBM file "/modsec_storage/global": Permission denied [hostname "www.internationalstudent.com"] [uri "/includes/soc_bookmarks/images/delicious.png"] [unique_id "LZ6jc38AAAEAAFO6408AAABO"] Failed to access DBM file "/modsec_storage/ip": Permission denied [hostname "www.internationalstudent.com"] [uri "/includes/soc_bookmarks/images/delicious.png"] [unique_id "LZ6jc38AAAEAAFO6408AAABO"] After following the instructions for file permission settings in the ModSecurity handbook by Ivan Ristic, with no success, I created a /modsec_storage directory, set the owner & group to apache, and set the permissions for the directory recursively to 777. However, ModSecurity is still reporting the same permission errors, so I am stumped. Can anyone tell me how to fix this?

• Drawing territories border in 2d map

  - by Gabriel A. Zorrilla

  I'm programming a little web strategy game. In the country map I pretend to display each country with a national color. The issue is how to render the borders in a simple and efficient way. Right now I'm planning to set a field to each tile called "border" with values from 0 to 8. The algorithm would check for EVERY tile is its adjacent has a different "owner". If the tile is inside the territory, the border value would be 0, because would not have adjacent any tile with different owner, if not, would vary between 1 (north) clockwise to 9 (north-west) and then draw the border. I find this simple but too processor-intensive. Are there any other "pro" choices to render territories borders?

• Setup basic proxypass in Apache

  - by Eric

  I have a web application that communicates to a web service deployed on the same server. The web app was written with Tibco General Interface and works well only when it is running locally on the development system. When I deploy the web app to the Apache server it fails with code 200 apparently due to cross domain data. I use Firefox as a browser. I have tried changing Internet Explorer to access cross domain data and it works however IE is not an option. Web application runs on 192.168.2.205 (port 80). Web service runs on 192.168.2.205:8040 I have tried a number of things with proxypass inside Apache with no luck.

• Question on refactoring and code design

  - by Software Engeneering Learner

  Suppose, I have a class with a constant static final field. Then I want in certain situations that field to be different. It still can be final, because it should be initialized in constructor. My question is, what strategy I should use: add this field value into the constructor create 2 subclasses, replace original field usage with some protected method and override it in subclasses Or create some composite class that will held instance of my class inside and somehow change that value? Which approach should I use and why?

• Square Reader Modified to Record Off Old Reel-to-Reel Tape [Video]

  - by Jason Fitzpatrick

  The Square Reader is a tiny magnetic credit card reader that has taken the mobile payment industry by storm. This clever hack dumps the credit card reading in favor of snagging the audio from old music reels. Evan Long was curious about whether the through-the-headphones interface of the Square Reader could be used to read audio data off old magnetic recordings. With a very small modification (he had to bend a metal tab inside the reader to allow the audio tape to slide through more easily) he was able to listen to and record audio off old reels. Watch the video above to see it in action or hit up the link below to read more about his project. iPod Meets Reel [via Make] HTG Explains: What Is Windows RT and What Does It Mean To Me?

• Is there any way to add a new location to the list of places where nltk looks for the wordnet corpus?

  - by Programming Noob

  I can't use the nltk wordnet lemmatizer because I can't download the wordnet corpus on my university computer due to access rights issues. I get the following error when I try to do so: ********************************************************************** Resource 'corpora/wordnet' not found. Please use the NLTK Downloader to obtain the resource: >>> nltk.download() Searched in: - '/home/XX/nltk_data' - '/usr/share/nltk_data' - '/usr/local/share/nltk_data' - '/usr/lib/nltk_data' - '/usr/local/lib/nltk_data' ********************************************************************** When I had the same issue at home, I could resolve it by two ways: Using nltk.download(), the standard way and Creating a new folder at location /home/XX/nltk_data and just pasting the corpus directory inside it. Now at the university I only have access to /home/XX/bin and not /home/XX directly. So is there anyway I could paste the wordnet corpus into /home/XX/bin and then somehow make nltk look for the corpus in that folder?

• Technologies similar to Flash and Silverlight for Desktop apps

  - by M.A. Hanin

  Long story short: we use Flash as a partial GUI in our .NET desktop applications. Normally, this means that the Flash player control sits in some WinForm, playing a movie file. Changes in the real world are presented in the movie (e.g., a light-bulb turned on in the real world? a matching one will light up inside the Flash movie), and interaction with the instances in the movie will affect the real world (clicked the light-bulb? the light bulb in the real world will turn on). My question is: which technologies / products can offer me similar capabilities? Of course, I'm looking for something that can compete with Flash / Silverlight: animations, object-oriented scripting and design, powerful tools allowing the artists to design symbols conveniently, etc... static image objects won't cut it

• How Lead-Acid Batteries Work [Video]

  - by Jason Fitzpatrick

  Every morning when you go out and start your car, you’re pulling power from a lead-acid battery. But how exactly do they work? In this informative video we see how lead plates and sulfuric acid provide the power your car craves. Courtesy of Engineer Guy Video: Bill explains the essential principles of a lead-acid battery. He shows the inside of motorcycle lead-acid battery, removes the lead and lead-oxide plates and shows how they generate a 2 volt potential difference when placed in sulfuric acid. He explains how the build up of lead sulfate between the plates will make the battery unusable if it discharged completely, which leads him to a description of how to make a deep cycle battery used for collecting solar energy.

• Matrix Pattern Recognition Algorithm

  - by Andres

  I am designing a logic analyzer and I would like to implement some Matrix Algorithm. I have several channels each one represented by a row in the matrix and every element in the column would be the state, for example: Channel 1 1 0 0 1 0 1 1 0 1 Channel 2 1 1 0 1 1 0 0 1 1 Channel 3 0 1 0 1 1 0 1 0 0 Channel 4 0 0 1 0 0 1 0 0 1 I would like to detect a pattern inside my matrix for example, detect if exist and where the sub-matrix or pattern: 1 0 1 1 I think it can be accomplished testing element by element but I think there should be a better way of doing it. Is there any Java API or any way to do it ? If there is a API ARM optimized for NEON instructions would be great also but not mandatory. Thank you very much in advance.

• How to produce assets effectively on large Flash game projects?

  - by Antoine Lassauzay

  I have been working on Flash games professionally for two years now and somehow, having our artists producing assets the right way is one of our biggest challenge. More precisely, it is very hard to have them following any kind of structure and/or standards, nor taking into consideration performance. I would say also the most of our issues concerns UI and related animations. Our current workflow is (on a Facebook hidden object game) : Artists produce PSD and animate prototypes in Flash Artists re-organize their FLA files to be a bit more "programmer friendly" Programmers retouches assets until they have the right structure and export classes inside a SWC, from Flash Programmers try to improve performances, sometimes degrading the quality of game graphics Our main idea is to hire somebody dedicated to prepare assets for programmers but I am really looking forward to improving the pipeline. I was wondering if you guys have tips of any kind to improve this workflow, whether it be team organization, training, tools or tips with Flash. Any explanation on your asset pipeline is well appreciated too.

• Mobile game production workflow using Html5 and visual studio

  - by Mihalis Bagos

  I want to know of any framework, that lets you build/test applications inside Visual Studio using Html5/JS. We need to be able to have an emulator (like the one on android sdk) for as many devices as possible, and we need to be able to run the application with as few steps as possible (using the "RUN" command in visual studio is no1 choice). Also, this extends to build and deployment to app stores. Is there a way to circumvent the cloud services and build locally? I am at a loss of the plethora of tools and technologies available for game design using Html5. However, I really don't like the way implementations try to get you to rely on their cloud services, so services like appmobi are at the bottom of the favored list.
