  • Thunderbird: "Could not initialize the application's security component" [closed]

    - by user unknown
    In Thunderbird, on startup, I get the error message: "Could not initialize the application's security component" The message continues to check permissions of the profile, and free disk space. df -h shows, that I have 19G free disk space. find . -not -perm -644 -not -perm -600 -ls shows: No file without rw-permissions for me. Before the error occured, thunderbird worked well. But I changed my main mail-account. I had two, let's call them A and B, and used mainly A, but now I wanted to deaktivate it, and receive and send automatically via the second. I Had problems moving the filters from inbox A to inbox B (missing copy-functionality). In the web, I found (mollazine) hints, to move key3.db, cert8.db and secmode.db out of the way, but it didn't work for me. Another hint was to uninstall Quickcam(?. sic!), but I don't have Quickcam. A third to recreate the profile, but I have subdirectories, filters, addressbook, groups - mails back to the year 2003. I don't want to risk the loss of data. The whole errormessage is: Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features. When I open the error-console, it is empty.

  • High-level description of how experimental C++ features are developed?

    - by Praxeolitic
    Herb Sutter in a video answers a question about the concepts proposal considered for C++11 and from his remarks it sounds like multiple groups offered prototype implementations but all of them left concerns about slow compile times. The comment surprised me because it suggests that, at least in some cases, the prototypes being developed are not just proofs of concept -- they're even expected to perform. All the work that must take has me curious. For mature languages, especially C++, how are experimental language features developed? Is it much different from developing a compiler that implements a standard? Does a developer have a sense of if it will work and perform or even if it ever could? What are the most time consuming parts and are any parts surprisingly easier than one might expect? The question is not what does the C++ standards committee do, but rather the part that comes before. When an experimental implementation for a proposal is being put together and there aren't any completely solidified rules, how is the sausage made? I'm not a professional compiler developer nor do I expect answers with step by step accounts. I'd like a high-level idea of how this would be done or if there are any general patterns at all. I don't know what to expect from the answers but even if there are no rules to the process and the small number of people who do this just cowboy it and then, for stuff that worked out, write up the "official version" as a proposal, that answer would still be informative.

  • Using 2d collision with 3d objects

    - by Lyise
    I'm planning to write a fairly basic scrolling shoot 'em up, however, I have run into a query with regards to checking for collision. I plan to have a fixed top down view, where the player and enemies are all 3d objects on a fixed plane, and when the enemy or player fires at the other, their shots will also be along this fixed plane. In order to handle the collision, I have read up a bit on collision detection in 3d, as it is not something I have looked into previously, but I'm not sure what would be ideal for this situation. My options appear to be: Sphere collision, however, this lacks the pixel precision I would like Detection using all vertexes and planes of each object, but this seems overly convoluted for a fixed plane of play Rendering the play screen in black and white (where white is an object, black is empty space), once for enemies and once for the player, and checking for collisions that way (if a pixel is white on both, there is a collision) Which of these would be the best approach, or is there another option that I am missing? I have done this previously using 2d sprites, however I can't use the same thinking here as I don't have the image to refer to.

  • batch file to disable network share on Windows XP

    - by Robb
    Loosely related to this question Network Share causing Cygwin to run slowly after 'ls', I'd like to write a little batch file that I can execute to disconnect the host from any network shares and subsequently another batch file to reconnect. Ideally, this would be something that I can execute from a PuTTY terminal, SSHed into the box running cygwin. I'm pretty sure the batch files can be written easily, but I don't know about executing them from a PuTTY terminal. Regardless, I'd still like the batchfiles anyways. For the sake of simplicity my process would be: Log into server via PuTTY Run batch files to disconnect shares Do what I need to do Run batch files to reconnect shares Exit session, closing PuTTY

  • C# 2d array value check [duplicate]

    - by TLFTN
    This question already has an answer here: 3-in-a-row or more logic 4 answers I've managed to create a 2d array, then made it fill up with random numbers, like this: int[,] grid = new int[5, 5] ; Random randomNumber = new Random(); var rowLength = grid.GetLength(0); var colLength = grid.GetLength(1); for (int row = 0; row < rowLength; row++) { for (int col = 0; col < colLength; col++){ grid[row, col] = randomNumber.Next(5); Console.Write(String.Format("{0}\t", grid[row, col]));} Console.WriteLine(); } This results in an array with random values. Example: 3 0 0 3 3 1 3 3 3 2 0 0 2 0 4 3 3 2 0 3 4 0 3 3 0 Notice those three 3s which are connected to each other(in the second row), now how would I check if there's a match like this?

  • 56.6 Modem with CallerID

    - by Fuod
    Does anyone still know anything about the 56.6 modems? I'm looking for one that is easy to access via C#/VB.Net, has Caller ID and is either low-profile or USB. Also that neat little feature that lets the modem block the call from the phone (pass-through) until it has received the CallerID info would be really nice! Obviously I could just go to Best Buy and get what they have but I have no way of knowing how friendly it would be to write code for and I don't want to make multiple trips returning/exchanging etc. I'm not going to be doing anything with voice or voice mail, just recording the number from CallerID. Thanks!

  • Beaglebone Black running Debian, does device tree overlay act as an api?

    - by user3953989
    This maybe more of a Linux specific question but... I've been reading many tutorials and it seems that you can use JavaScript, Python, and C++ to write code for the Beaglebone Black(BBB). It looks like the way C++ interfaces with the BBB hardware is via reading/writing text files on the OS while Python has it's own library. All the C++ examples out there control the GPIO and PWM via reading/writing to text files. Is this the only way to access the hardware or just how Linux does drivers?

  • IIS 7 with PHP in Domain with Windows Authentication

    - by Michal Saiyan Hajdony
    I have Windows Server 2008 R2 x64b installed with IIS 7, PHP 5.5. This server is added to domain exampledomain , so I have win authentication enabled and all others disabled. I left the two default providers NTLM and negotiate, I granted IIS_IUSRS read access to wwwroot. So far it has worked for me only as I am added to the Administrators group which has read/write access to wwwroot folder. Yet, when someone else is trying to connect, he gets a credentials window and when he puts the domain name and password he cannot get access to the page. The issue is solved when I add read permission to "Domain users" - then all works fine. BUT. My issue is that if one opens windows explorer and types \\servername\wwwroot one can see the files and read them. I have never configured IIS before so I know I miss some really important thing. How can I solve the file visibility problem?

  • Is it safe to use up all memory on linux server, not leaving anything for the cache?

    - by Temnovit
    I have a CentOS server fully dedicated to MySQL 5.5 (with innodb tables mostly). Server has 32 GB RAM, SSD disks, and avarage memory usage looks like this: So about 25GB is in use and about 6.5GB is cached. I am experiencing performance problems with WRITE queries, so I was thinking, is this the optimal cache size? I might increase innodb buffer size, so that linux cache would become smaller, or decrease it, so it would be bigger. What is the optimal used/cached memory balance for busy MySQL server on linux?

  • Versioning files in Windows XP

    - by Mike Cole
    I would like to set up an archive folder in Windows XP that would allow me to drop several different versions of the same file, and have it store each version. I would envision this to work similar to the recycle bin, where you can drop the same file 10 times and it stores each version. Anybody know how I can do this? Thanks! Edit: Using a Version Control System is complete overkill for this situation. I may just write a script that appends a date/time stamp to the file when added to the folder.

  • What's the advantage of using a bash script for cron jobs?

    - by AlxVallejo
    From my understanding you can write your crons by editing crontab -e I've found several sources that instead refer to a bash script in the cron job, rather than writing a job line for line. Is the only benefit that you can consolidate many tasks into one cron job using a bash script? Additional question for a newbie: Editing crontab -e refers to one file correct? I've noticed that if I open crontab -e and close without editing, when I open the file again there is a different numerical extension such as: "/tmp/crontab.XXXXk1DEaM" 0L, 0C I though the crontab is stored in /var/spool/cron or /etc/crontab ?? Why would it store the cron in the tmp folder?

  • Lenovo N100 and Samsung SSD 830, shouldn't this go faster than 100MB/s?

    - by Jook
    I recently upgrated my Lenovo N100 0768 with a Samsung SSD 830 - specified to support 520 MB/s read and 320MB/s write. However, having only SATA1 with max. of 150MB/s speed, it has to run in a slower mode - of course. But, shouldn't it be more on the edge of this limit than ranging between 90-115MB/s and averaging around 103MB/s? Or is this really as much as I can expect? Tested with HD-Tach. Has anyone comparable results on a SATA1 controller with a SSD drive faster than SATA1? Preferably similar to the Samsung 830?

  • Which jar has JBox2d's p5 package

    - by Brantley Blanchard
    Using eclipse, I'm trying to write a simple hello world program in processing that simply draws a rectangle on the screen then has gravity drop it as seen in this Tutorial. The problem is that when I try to import the p5 package, it's not resolving so I can't declare my Physics object. I tried two things. Download the zip, unzip it, then import the 3 jars (library, serialization, & testbed) a. import org.jbox2d.p5.*; doesn't resolve but the others do b. Physics physics; doesn't resolve Download the older standalone testbed jar then import it a. Physics physics; doesn't resolve; Here is basically where I'm starting import org.jbox2d.util.nonconvex.*; import org.jbox2d.dynamics.contacts.*; import org.jbox2d.testbed.*; import org.jbox2d.collision.*; import org.jbox2d.common.*; import org.jbox2d.dynamics.joints.*; import org.jbox2d.p5.*; import org.jbox2d.dynamics.*; import processing.core.PApplet; public class MyFirstJBox2d extends PApplet { Physics physics; public void setup() { size(640,480); frameRate(60); initScene(); } public void draw() { background(0); if (keyPressed) { //Reset everything physics.destroy(); initScene(); } } public void initScene() { physics = new Physics(this, width, height); physics.setDensity(1.0f); physics.createRect(300,200,340,300); } }

  • IE session (-nomerge) manager

    - by skrco
    I'm looking for an application that can manage (save/open) multiple Internet Explorer instances (to be precise nomerge sessions), host them in single window and arrange these instances e.g. in tabs, so in result you have double tab bar. In functionality it's similar to Remote Desktop Manager, where you can create Web session, but in embedded mode you cannot set the nomerge option. I've been searching the web, but with no results. So I put this question whether anyone know of such application or workaround. Or I have to write my own app.

  • need a different backup solution

    - by DigitalJedi
    I just built a new media/backup server using Ubuntu 12.04 64bit. I installed a hard drive to be used only for music, pictures, and videos and formatted it fat32 so my 1 and only Windows PC could map those folders as netshares. My laptop, also running Ubuntu 12.04, is what I am using the most so new media is first downloaded on my laptop. I've already got the music, videos, and pictures folders from my server mounting as shares on my laptop on boot thanks to some fstab edits and sshfs. Now I'm wanting either an app or script that could backup any new files I add to my local media folders to the mounted folders on my server. I've been Googling all day and found a few apps like rsync but they seem to have issues with ext4 to vfat backups. I thought maybe a script would be best but I'm new to scripting in Linux and don't want to mess anything up. Basically I am looking for something that will backup only newly added files to the server. I figure I could schedule it once a week. There are some stipulations. For example, my local music folder has over 700 folders for each artist/band then sub folders inside those for albums. I want something smart enough to only copy newly added content so I'm guessing the modified date would probably be a good condition if I were scripting. I'm rambling. Any suggestions would be GREATLY appreciated. I'm not finding anything to suit my needs. I'm almost to the point of just learning bas scripting so I can write something but then it will be a couple weeks or so before I have a possible solution and I'd like something in place sooner.

  • Trying to mount an NFS directory from a Mac with another user

    - by Yair
    I have a username on an ubuntu server, lets call it user a. I want to mount a directory from that server to my Mac, on which I have another username, lets call it user b. My problem is that, after I mount the directory (using the disk utility app) I can view files on the server but can't modify or create new files on it. I checked, and if I change the permissions of the server directory so that its open to everyone (chmod 777), I can write to it. So what I need to know, is how can I specify the username and password in the NFS client when setting up the mount? That is, I want to specify that I'm trying to log in as user a to the server.

  • Storage sizing for virtual machines

    - by njo
    I am currently doing research to determine the consolidation ratio my company could expect should we start using a virtualization platform. I find myself continually running into a dead end when researching how to translate observed performance (weeks of perfmon data) to hdd array requirements for a virtualization server. I am familiar with the concept of IOPs, but they seem to be an overly simplistic measurement that fails to take into account cache, write combining, etc. Is there a seminal work on storage array performance analysis that I'm missing? This seems like an area where hearsay and 'black magic' have taken over for cold, hard fact.

  • node.js server not running

    - by CMDadabo
    I am trying to learn node.js, but I'm having trouble getting the simple server to run on localhost:8888. Here is the code for server.js: var http = require("http"); http.createServer(function(request, response) { response.writeHead(200, {"Content-Type": "text/plain"}); response.write("Hello World"); response.end(); }).listen(8888); server.js runs without errors, and trying netstat -an | grep 8888 from terminal returns tcp4 0 0 *.8888 *.* LISTEN However, when I go to localhost:8888 in a browser, it says that it cannot be found. I've looked at all the related questions, and nothing has worked so far. I've tried different ports, etc. I know that my router blocks incoming traffic on port 8888, but shouldn't that not matter if I'm trying to access it locally? I've run tomcat servers on this port before, for example. Thanks so much for your help! node.js version: v0.6.15 OS: Mac OS 10.6.8

  • Debian: Give users permission

    - by 50ndr33
    I have a www-data that was automatically set up when I installed Apache. I have a ftpuser that I configured myself to use with ProFTPd. I use a MySQL database with users that use this user to log on. The problem is that Apache with PHP is working as it should, but I cannot add files with FTP. I tried to do chmod 777 mysite.com, and it worked, but now Apache gave me a 500 internal error. I suppose chmod isn't the correct way to go. I deleted my folder and made a new one. How can I give ftpuser permissions to read and write, while www-data should not loose its permissions. I don't have much experience with Linux command line. Thanks!

  • How do I develop database-utilizing application in an agile/test-driven-development way?

    - by user39019
    I want to add databases (traditional client/server RDBMS's like Mysql/Postgresql as opposed to NoSQL, or embedded databases) to my toolbox as a developer. I've been using SQLite for simpler projects with only 1 client, but now I want to do more complicated things (ie, db-backed web development). I usually like following agile and/or test-driven-development principles. I generally code in Perl or Python. Questions: How do I test my code such that each run of the test suite starts with a 'pristine' state? Do I run a separate instance of the database server every test? Do I use a temporary database? How do I design my tables/schema so that it is flexible with respect to changing requirements? Do I start with an ORM for my language? Or do I stick to manually coding SQL? One thing I don't find appealing is having to change more than one thing (say, the CREATE TABLE statement and associated crud statements) for one change, b/c that's error prone. On the other hand, I expect ORM's to be a low slower and harder to debug than raw SQL. What is the general strategy for migrating data between one version of the program and a newer one? Do I carefully write ALTER TABLE statements between each version, or do I dump the data and import fresh in the new version?

  • Why is the remove function not working for hashmaps? [migrated]

    - by John Marston
    I am working on a simple project that obtains data from an input file, gets what it needs and prints it to a file. I am basically getting word frequency so each key is a string and the value is its frequency in the document. The problem however, is that I need to print out these values to a file in descending order of frequency. After making my hashmap, this is the part of my program that sorts it and writes it to a file. //Hashmap I create Map<String, Integer> map = new ConcurrentHashMap<String, Integer>(); //function to sort hashmap while (map.isEmpty() == false){ for (Entry<String, Integer> entry: map.entrySet()){ if (entry.getValue() > valueMax){ max = entry.getKey(); System.out.println("max: " + max); valueMax = entry.getValue(); System.out.println("value: " + valueMax); } } map.remove(max); out.write(max + "\t" + valueMax + "\n"); System.out.println(max + "\t" + valueMax); } When I run this i get: t 9 t 9 t 9 t 9 t 9 .... so it appears the remove function is not working as it keeps getting the same value. I'm thinking i have an issue with a scope rule or I just don't understand hashmaps very well. If anyone knows of a better way to sort a hashmap and print it, I would welcome a suggestion. thanks

  • Windows 8 on iSCSI with LIO target: thin provisioning

    - by LubosD
    I have installed Windows 8.1 on an iSCSI target. This target is provided by Linux LIO and is backed by a sparse file. One of the reasons I created such an installation was thin provisioning. In other words, when I free disk space on Windows, LIO should punch holes into the file, thus free storage space on the Linux server as well. I have checked my kernel's sources and the SCSI UNMAP command is really supported for file-backed targets. On the other hand, deleting files on Windows doesn't lower the amount of space taken by the backing file on Linux (checked with du). Actually, the backing file sometimes grows even more. Some sources on Google say Win8 should support UNMAP/DISCARD on iSCSI, but even in Wireshark I only see ordinary read and write commands when files are being deleted. Any way to fix or troubleshoot it?

  • how to recover lost partitions data

    - by TheJoester
    I have a 2TB SATA drive that was being used as file storage on my UBUNTU computer. I was re-imaging my windows box so I used that drive to back up some files to it. I did this by taking the drive from my windows PC and putting it in my UBUNTU PC, mounted it and copied the files over. After the windows refresh I thought it would be easier to take the 2 TB drive and dock it in the external dock my Windows case has built in. Anyway it would recognize in BIOS but windows would not see it (because it was EXT3 or EXT4) so when I went into the disk manager it advised me the drive needed to be initialized. Me not thinking I initialized it as a GUID Partition table. Now it sees it as a blank drive, even in UBUNTU. I have done nothing else to write or change the drive. I was wondering if there is a qay to repair the old partitioning and get access to my files back? many thanks! EDIT: I followed the instructions in the link @kniwor sent me. I used the command sudo gpart -W /dev/sda /dev/sda and here was the result: Guessed primary partition table: Primary partition(1) type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) size: 0mb #s(1) s(2861671176-2861671176) chs: (1023/254/63)-(1023/254/63)d (178130/202/1)-(178130/202/1)r Primary partition(2) type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) size: 0mb #s(1) s(3484550160-3484550160) chs: (1023/254/63)-(1023/254/63)d (216903/55/1)-(216903/55/1)r Primary partition(3) type: 000(0x00)(unused) size: 0mb #s(0) s(0-0) chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r Primary partition(4) type: 000(0x00)(unused) size: 0mb #s(0) s(0-0) chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r Not sure it found what I wanted. suggestions?

  • To program in free time as a programmer, is to show that programming is passion. If not, is the programmer good? [closed]

    - by SonofWatson
    Possible Duplicate: I don't program in my spare time. Does that make me a bad developer? A lot of blogs and advice on the web seem to suggest that in order to become a great developer, doing just your day job is not enough. For example, you should contribute to open source projects in your spare time, write smartphone apps, etc. In fact a lot of this advice seems to suggest that if you don't love programming enough to do it all day long then you're probably in the wrong career. That doesn't ring true with me. I enjoy my work, but when I come home from the office I'm not in the mood to jump straight back onto the computer and start coding away until bedtime. I only have a certain number of hours free time each day, and I'd rather spend them on other hobbies, seeing friends or going outside than in front of the computer. I do get a kick out of programming, and do hack around outside of work occasionally. I'm committed to my personal development and spend time reading tech blogs and books as a way to keep learning and becoming better. But that doesn't extend so far as to my wanting to use all my spare time for coding. Does this mean I'm not a 'true' software developer at heart? Is it possible to become a good software developer without doing extra outside your job? I'd be very interested to hear what you think.

  • ubuntu 9.10 on an external usb drive: grub1 does not work

    - by Toc
    I have installed Ubuntu on a partition of my external usb drive. Since I had problems with grub2, I have uninstalled it and installed grub1. But then the usb drive didn't boot anymore, and I am forced to the limited shell of grub1. If I write manually kernel (hd0,4)/vmlinuz-2.6.31-15-generic root=/dev/sdb4 ro quiet splash initrd (hd0,4)/boot/initrd.img-2.6.31-15-generic boot then Ubuntu is loaded, but if I execute the commands root (hd0,4) setup (hd0) as explained at http://www.gnu.org/software/grub/manual/html_node/Installing-GRUB-natively.html#Installing-GRUB-natively, next time I boot from usb I am forced again to the grub limited shell. How can I restore a working grub?
