  • Finding easily parseable chemical element data

    - by nickname
    I am writing an application that needs simple data found (mostly) on the periodic table of elements, such as atomic mass, atomic number, state, etc. However, I would prefer not to manually enter this data. I managed to find the NIST website (http://www.nist.gov/pml/data/edi.cfm) with all of the data I need, but not in a downloadable format. Where can I find this data? Preferably, it would be in an XML/YAML/JSON/other documented format, however, any format would be helpful.

  • Sharing accounts between multiple computers running Ubuntu Linux

    - by john
    My school has a computer lab full of machines running Red Hat Linux. They have it set up so that you can log into any computer in the lab, and it automatically loads your desktop, home directory, etc, which makes it so all computers in the lab look the same to you, regardless or which one you're using. I have two computer at home running Ubuntu Linux. Could I do this same thing with my computers at home? What's it called, and how do I find documentation on how to set it up? Thanks!

  • How to program simple chat bot AI?

    - by Larsenal
    I want to build a bot that asks someone a few simple questions and branches based on the answer. I realize parsing meaning from the human responses will be challenging, but how do you setup the program to deal with the "state" of the conversation? EDIT: It will be a one-to-one conversation between a human and the bot.

  • CD-R suddenly unreadable?

    - by TheD
    I have a CD-R which has worked fine for a good while. All of a sudden, Windows can no longer read its data. It's not scratched, it's clean and Windows can detect the disk and usage of space on it. But whenever I attempt to access the data stored: Explorer crashes Or after 5-10 mins of trying to read it, it opens up and just shows a desktop.ini file in Explorer. This happens on multiple machines. Any ideas? Is there a way to recover the data? For example - some sector by sector recovery software if any exist for CD's?

  • Thin web server - single or multiple instances per IP address:port?

    - by wchrisjohnson
    I'm deploying a rack/sinatra/web socket app onto several servers and will use thin as the web server (http://code.macournoyer.com/thin/). There are almost no views to show, so I am not front-ending it with a traditional web server like Apache or nginx. In general, you see thin started and the underlying config file for it has the number of server instances to start, say 3, and the port to start with, say 5000. So, in my example, when thin starts, it starts up three instances on a range of ports, starting on port 5000. If I have a series of virtual machines, say 3, 6, 9, etc. that I treat as a cluster, would/should I choose to start a single thin instance on each VM, or multiple instances on each VM? Why? Thanks - Chris

  • How to install remote software NOT on a domain?

    - by Nicros
    I have a situation where some software (that I wrote) is going to be deployed on 60 laptops for an event. The laptops are all running windows 7, but there is no domain controller, and they will all be connected to a 192.168.x.x network using wifi. Is there any convenient way to push the software (consisting of an msi file) can be pushed out to all the laptops and installed? I looked at WMIC, but I think that requires machines be joined to a domain, as does Group Policy. The other alternative is Powershell, but I have literally 4 hours to do this and will have no time to figure out the right script. It's not the end of the world if it has to be done manually (I can find volunteers) but it would be nicer if it could be automated somehow.

  • Lustre - is this bad form?

    - by ethrbunny
    Im going to be consolidating several 'server rooms' into a single installation soon. Part of this effort will be finding a home for 5Tb (and growing) of files / logs. To this end Im looking at Lustre and appreciating its ability to scale. The big vendors want to sell me a $20K SAN to manage this but Im wondering about buying several iSCSI units (like this http://www.asacomputers.com/3U-iSCSI-Solution.html) and using VMs for the OSS machines. This would let me fail-over to cover problems and not require a dedicated system for each OSS. Given articles like this (http://h30565.www3.hp.com/t5/Feature-Articles/RAID-Is-Dead-Long-Live-RAID/ba-p/1422) that talk about how RAID is not keeping up with drive density Im leaning towards more disks with lower capacity each. Again - some akin to the iSCSI array above. Tell me why this is a terrible idea. Do I really need to invest in a PE710 for each OSS/OST?

  • nmap reports host up when it isn't

    - by martianway
    On an Ubuntu VM I ran: sudo nmap -sP 192.168.0.* This returned: Starting Nmap 5.00 ( http://nmap.org ) at 2010-12-28 22:46 PST Host 192.168.0.0 is up (0.00064s latency). Host 192.168.0.1 is up (0.00078s latency). Host 192.168.0.2 is up (0.00011s latency). . . . Host 192.168.0.254 is up (0.00068s latency). Host 192.168.0.255 is up (0.00066s latency). The problem is I only have 4 live machines on 192.168.0.* so why did nmap report every ip in the subnet has a live host? The ip address of the Ubuntu machine is 192.168.28.131 From this VM I can ping the live systems on my internal subnet 192.168.0.* and get the expected response. And if I ping a machine that doesn't exist I can get no response as expected.

  • Setup local EC2 style cloud?

    - by John Kramlich
    I was recently given 3 dual opteron 2400 servers with 4GB of RAM and 120GB hard drives. I am interested in setting up something similar to Amazon's EC2 for my own personal web development use. Basically, I would like to spin up instances from an ISO or other disk images and have them available to test and develop software. Are there open source solutions I can use to accomplish this? I am assuming one of the machines will need to act as a controller of some sort for the other two. I use Sun's VirtualBox on my local development machine to virtualize various versions of Microsoft Windows. However, I'm not sure if that's the best tool for what I am trying to achieve. I apologize in advance if this question is to vague to get meaningful responses. I am new to cloud computing and fairly new at server administration.

  • Get the "source network address" in Event ID 529 audit entries on Windows XP

    - by Make it useful Keep it simple
    In windows server 2003 when an Event 529 (logon failure) occures with a logon type of 10 (remote logon), the source network IP address is recorded in the event log. On a windows XP machine, this (and some other details) are omitted. If a bot is trying a brute force over RDP (some of my XP machines are (and need to be) exposed with a public IP address), i cannot see the originating IP address so i don't know what to block (with a script i run every few minutes). The DC does not log this detail either when the logon attempt is to the client xp machine and the DC is only asked to authenticate the credentials. Any help getting this detail in the log would be appreciated.

  • Windows Home Server is showing signs of death

    - by Guy
    I have a Windows Home Server (HP EX485 MediaSmart Home Server) and it started acting up about 4 weeks ago and a few days ago complained of a corrupt database and would I like to try and recover it? Yes, I would but I ended up losing all backups. I have to reboot it frequently for the client machines to be able to see it. I have 4 hard disks in the computer. I suspect that the primary hard disk is going bad. My first question: How can I confirm if it's going bad or not? I'm thinking about removing the primary disk and replacing it with one of the others and reloading the OS with the server restore disk. I know that I'll lose everything (but I recently did anyway) but is there any other reason why I should not do this?

  • Does CakePHP treat all INT fields as ID's for join tables?

    - by Jonnie
    I am trying to save a User, their Profile, and some tags and my join table that links the profile and the tags keeps getting messed up. The profile model is called Instructor, the tag model is called Subject. The Instructor has a phone number and a zip code and for some reason CakePHP thinks these are the fields it should use when creating entries in my join table. My Join table always comes out as: id | instructor_id | subject_id | 1 | 90210 | 1 | // thinks that the zip code is an instructor_id 2 | 1112223333 | 1 | // thinks that the phone number is an instructor_id 3 | 1 | 1 | // thinks that user_id is an instructor_id 4 | 1 | 1 | // the actual instructor_id, this one's correct 5 | 90210 | 2 | 6 | 1112223333 | 2 | 3 | 1 | 2 | 4 | 1 | 2 | My Models: class Instructor extends AppModel { var $name = 'Instructor'; var $belongsTo = array('User', 'State'); var $hasAndBelongsToMany = array( 'Subject' = array( 'className' = 'Subject', 'joinTable' = 'instructors_subjects', 'foreignKey' = 'instructor_id', 'associationForeignKey' = 'subject_id', 'unique' = true, 'conditions' = '', 'fields' = '', 'order' = '', 'limit' = '', 'offset' = '', 'finderQuery' = '', 'deleteQuery' = '', 'insertQuery' = '' ) ); } class Subject extends AppModel { var $name = 'Subject'; var $hasAndBelongsToMany = array( 'Instructor' = array( 'className' = 'Instructor', 'joinTable' = 'instructors_subjects', 'foreignKey' = 'subject_id', 'associationForeignKey' = 'instructor_id', 'unique' = true, 'conditions' = '', 'fields' = '', 'order' = '', 'limit' = '', 'offset' = '', 'finderQuery' = '', 'deleteQuery' = '', 'insertQuery' = '' ) ); } My Model Associations: User hasOne Instructor Instructor belongsTo User Instructor hasAndBelongsToMany Subject Subject hasAndBelongsToMany Instructor My form data looks like: Array ( [User] = Array ( [username] = MrInstructor [password] = cddb06c93c72f34eb9408610529a34645c29c55d [group_id] = 2 ) [Instructor] = Array ( [name] = Jimmy Bob [email] = [email protected] [phone] = 1112223333 [city] = Beverly Hills [zip_code] = 90210 [states] = 5 [website] = www.jimmybobbaseballschool.com [description] = Jimmy Bob is an instructor. [user_id] = 1 [id] = 1 ) [Subject] = Array ( [name] = hitting, pitching ) ) My function for processing the form looks like: function instructor_register() { $this-set('groups', $this-User-Group-find('list')); $this-set('states', $this-User-Instructor-State-find('list')); if (!empty($this-data)) { // Set the group to Instructor $this-data['User']['group_id'] = 2; // Save the user data $user = $this-User-save($this-data, true, array( 'username', 'password', 'group_id' )); // If the user was saved, save the instructor's info if (!empty($user)) { $this-data['Instructor']['user_id'] = $this-User-id; $instructor = $this-User-Instructor-save($this-data, true, array( 'user_id', 'name', 'email', 'phone', 'city', 'zip_code', 'state_id', 'website', 'description' )); // If the instructor was saved, save the rest if(!empty($instructor)) { $instructorId = $this-User-Instructor-id; $this-data['Instructor']['id'] = $instructorId; // Save each subject seperately $subjects = explode(",", $this-data['Subject']['name']); foreach ($subjects as $_subject) { // Get the correct subject format $_subject = strtolower(trim($_subject)); $this-User-Instructor-Subject-create($this-data); $this-User-Instructor-Subject-set(array( 'name' = $_subject )); $this-User-Instructor-Subject-save(); echo ''; print_r($this-data); echo ''; } } } } }

  • Timer vs setTimeout

    - by Christophe Herreman
    The docs for flash.utils.setTimeout() state: Instead of using this method, consider creating a Timer object, with the specified interval, using 1 as the repeatCount parameter (which sets the timer to run only once). Does anyone know if there is a (significant) advantage in doing so? Using setTimeout is a lot easier when you only need to delay 1 call.

  • OpenGL, how to set a monocrome texture to a colored shape?

    - by Santiago
    I'm developing on Android with OpenGL ES, I draw some cubes and I change its colors with glColor4f. Now, what I want is to give a more realistic effect on the cubes, so I create a monochromatic 8bit depth, 64x64 pixel size PNG file. I loaded on a texture, and here is my problem, witch is the way to combine the color and the texture to get a colorized and textured cubes onto the screen? I'm not an expert on OpenGL, I tried this: On create: public void asignBitmap(GL10 gl, Bitmap bitmap) { int[] textures = new int[1]; gl.glGenTextures(1, textures, 0); mTexture = textures[0]; gl.glBindTexture(GL10.GL_TEXTURE_2D, mTexture); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); gl.glTexEnvf(GL10.GL_TEXTURE_ENV, GL10.GL_TEXTURE_ENV_MODE, GL10.GL_REPLACE); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, GL10.GL_ALPHA, bitmap, 0); ByteBuffer tbb = ByteBuffer.allocateDirect(texCoords.length * 4); tbb.order(ByteOrder.nativeOrder()); mTexBuffer = tbb.asFloatBuffer(); for (int i = 0; i < 48; i++) mTexBuffer.put(texCoords[i]); mTexBuffer.position(0); } And OnDraw: public void draw(GL10 gl, int alphawires) { gl.glColor4f(1.0f, 0.0f, 0.0f, 0.5f); //RED gl.glBindTexture(GL10.GL_TEXTURE_2D, mTexture); gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA); gl.glEnable(GL10.GL_TEXTURE_2D); gl.glEnable(GL10.GL_BLEND); gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY); gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, mTexBuffer); //Set the face rotation gl.glFrontFace(GL10.GL_CW); //Point to our buffers gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertexBuffer); //Enable the vertex and color state gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); //Draw the vertices as triangles, based on the Index Buffer information gl.glDrawElements(GL10.GL_TRIANGLES, 36, GL10.GL_UNSIGNED_BYTE, indexBuffer); //Disable the client state before leaving gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY); gl.glDisable(GL10.GL_BLEND); gl.glDisable(GL10.GL_TEXTURE_2D); } I'm even not sure if I have to use a blend option, because I don't need transparency, but is a plus :) Thank's

  • Screen rotation hot key (CTRL+ALT+UP) not responding, what's going on?

    - by Jamie
    The other day my son (11 months) discovered a new hot key combination on my laptop. As I'm sure many of you are aware (I wasn't until the other day), on machines with Intel Graphics, pressing CTRL+ALT+{any arrow key} rotates the screen. After I recovered from my shock, and did a little sideways Googling to figure out how to fix it, I decided this might actually be useful. I read a lot of online documentation, and it fits better on the screen when it's rotated. Since it's a laptop, I hold the machine like a book and read it. It worked great all afternoon yesterday. But today at work I tried to show a friend this new trick, using the same laptop, and found that the CTRL+ALT+UP no longer works. I can rotate it to any orientation but the normal one. I'm guessing something else is intercepting this hot key, but what could be doing this?

  • Unable to deactivate windows xp by modifying the license in the registry

    - by ConorWalsh
    I need to deactivate windows xp so I can set it up with a new license. Every tutorial I've visited follow the same steps. (Example http://www.ehow.com/how_6665848_deactivate-windows-xp-pro.html) The tutorials state that the 00BE timer file located in the registry needs to be modified. It is found by going to the registry and navigating through "HKEY_LOCAL_MACHINE," "Software," "Microsoft," "WindowsNT," "CurrentVersion" and "WPAEvents." After the file is modified Windows should be deactivated. However it never does. The value changes but when I run the command to add a new license key it states "windows is already activated". I've done this before on other machines at it worked fine. I can't find any other methods to change the license in XP. Has anyone ever had this issue or knows of another way of deactivating windows?

  • Black screen after scheduled resume from sleep

    - by macbirdie
    I have a problem with my two Windows 7 setups at home. Whenever a scheduled task wakes up the machines from sleep, a black screen with a mouse cursor appears. If I move the mouse or press any key, desktop appears. The biggest problem is that during that black screen phase the display, sometimes even the PC too, doesn't go to stand by after a set period of time in power settings. If I get the desktop to show up, standby functions work fine. Display goes blank after a few minutes and as soon as the task doesn't need the PC, it goes back to sleep. It's frustrating that this "feature" is wasting energy and keeps lighting up the pc in the middle of the night for me to find it that way after I wake up. I found a handful of threads on the intertubes about the issue, but there were no answers in any of them. It sometimes happens in my XP machine at work as well.

  • EF recovery from invalidoperationexception caused by server being down

    - by Jonn
    I had a windows service relying on EF, and it was running fine until the server went down. The problem was after the server went up again, it didn't fix itself and still threw the error: INTERNAL ERROR: Execution of the command requires an open and available connection. The connection's current state is broken. Not being very proficient in EF I'm not aware of how I could recover from such a scenario, and why it occurred in the first place? Anyone had this happen before?

  • Running IPv4 program in IPv6 network

    - by stobyer
    I have an IPv4 windows client program and IPv4 Linux server. What I need is to run them in pure IPv6 network, although machines have dual stack. At the beginning I thought it's not a problem: I'll use 4in6 protocol (rfc2473) and that's all. I found a simple guide for Linux configuration here, but when I started to configuring windows 7, I couldn't find how to do it. There are plenty of info on how to tunnel IPv6 over IPv4 (6in4, Teredo) but not an opposite. Does anyone know how to do it? Thank you.

  • How can I stream video from my XP sp3 desktop to my win 7 laptop?

    - by Robb
    I would like to stream media from my XP sp3 desktop to my Win7 laptop. I currently have Windows Media Player 11 on both machines. The XP one is set up for the media sharing service as far as I can tell. I have also set the 'Play To' option to my Win 7 machine on the XP WMP. However, the only way I've been able to 'stream' is to simply tell my Win7 WMP to add a network folder to its libraries. This seems to work over the wifi but it does stutter a touch, even with a 20 second buffer. The stuttering also appears randomly, maybe 4-5 times during a 22 minute show. I feel like I'm doing something wrong. Is this setup OK or am I missing something?
