  • Programming language for simple program?

    - by jamherst
    I am wondering about which programming languages people see fit to create a program idea that I had. I am looking to create a fairly simple program whose main functions are adding to, managing, and searching through a database of people, all through a polished GUI. It will be for use in the business world, so I think Windows would be the priority, but Mac and Linux support wouldn't be bad. Also, eventually I would like to add the ability for an instance of one program on a computer to interact with other instances on the same network, mainly through the sharing of a database. Most of my experience is in Java, but I don't particularly like the appearance of Java GUIs, so I'm looking for an alternative. I noticed that a lot of people have suggested C++ or C# in similar posts, so what are some of the advantages/disadvantages of one or both if that is your suggestion. Thanks for any help in advance.

  • Receive anonymous users' input by web upload form or email. Any online service for that?

    - by sja
    Are you aware of any online service or online "platform" allowing users, not previously registered, to upload pairs of picture+comment to a database? It would be a collaborative database of picture+comment pairs. I'm not going wiki or googlegroup, picasa or such because I'd like the user to have the least to do to participate, that is e.g.: take a picture with his phone and email it to an email to an email address. Or go to a web page with an upload form, type in a description, hit OK and that's it. And the goal is also that it be as hassle-less to put up as possible. Yeah I know, it can't programme itself to my requirements :) by I'm suspecting there's a tool or tool combination going a decent way through my needs. Thanks for any info/advice! SJA (NB the final goal is a kind of crowd-sourced census of specific urban items. If you have comment about the potential for spam-overload of my idea, other than "you're doomed", you're welcome!)

  • How do I update Safari on Windows?

    - by James A. Rosen
    I'd like to update Safari to 4.0.5 for security reasons, but I can't figure out how to run the Apple updater manually. On Mac there's usually a "Check for Updates" menu item, but I don't see one on the Windows version. I tried downloading the latest version from http://www.apple.com/safari/download/, but Windows won't let me open the file, saying it is a security risk.

  • Safety concerns on allowing connections to MySQL with no password on localhost?

    - by ÉricO
    In the case of a Linux system, is there any security concern to let MySQL users with standard privileges (that is, not the root users) connect to the database with no password from localhost? I think that enforcing a password even for localhost can add a layer of protection, since, with no password the database access would be compromised if the SSH access is itself compromised. Considering that, would it be less safe to allow no password connection to MySQL than having the same password for SSH and for MySQL? I don't know if that is to be taken into account, but we also use phpMyAdmin to let users administrate their own database. I am asking because I kinda dislike having to put our database passwords unencrypted in the source or configuration files of our applications, where they can easily be leaked unintentionally. Since our servers are configured to run our applications as the Linux user the application belongs to, I was considering allowing no password from localhost as a simple solution. So, would that be a very bad idea or not?

  • What are the best settings of the H2 database for high concurrency?

    - by dexter
    There are a lot of settings that can be used in H2 database. AUTO_SERVER, MVCC, LOCK_MODE, FILE_LOCK and MULTI_THREADED. I wonder what combination works best for high concurrency setup e.g. one thread is doing INSERTs and another connection does some UPDATEs and SELECTs? I tried MVCC=TRUE;LOCK_MODE=3lFILE_LOCK=NO but whenever I do some UPDATEs in one connection, the other connection does not see it even though I commit it. By the way the connections are from different processes e.g. separate program.

  • How to create a user customizable database (like Zoho creator) in Rails?

    - by martjno
    I'm learning Rails, and the target of my experiments is to realize something similar to Zoho Creator, Flexlist or Mytaskhelper, i.e. an app where the user can create his own database schema and views. What's the best strategy to pursue this? I saw something about the Entity-Attribute-Value but I'm not sure whether it's the best strategy or if there is some support in Rails for it. If there was any tutorial in Rails about a similar project it would be great. Probably it's not the easiest star for learning a new language and framework, but it would be something I really plan to do since a long time.

  • database modeling for google app engine for multiple revison of entity.

    - by iamgopal
    hi, in my application ( kind of wiki clone ) - an article is frequently changing. and i need to track all changes that are done on that article. { text only. } one crude way i have done it, is to add a datetime property and create a new entity everytime something change. which is too much database wasting. { and also un-necessary index waste too. } and also need to re-create parent-child and entity relationships. i also have log which can show changes -- but i want some thing easier , so that jumping from one version to another version could be easier. ideas ? thanks.

  • Windows Security popup window pops up each time any connection is made

    - by MC Emperor
    I have a problem with the Windows Security popup below. It pops up every time the system tries to make connection with any internet source. It's very annoying, and I don't know how to resolve the problem. (The popup window below is in Dutch, but says something like Connect to somedomain.com. Then it expects you to give your credentials.) I am running on a Windows 7 x64 OS. Now how do I solve this problem? Is it a Windows Firewall problem?

  • How to separate database entries and display them as individual records using PHP?

    - by Clark
    I used to have database entries separated by ampersands (&), but this was causing certain search issues so I decided to encapsulate my entries on both sides by $ and & symbols like: $this& But I am having trouble displaying all the entries of a cell as individual records. Before I used: $unsplitItems = $row['files']; $files = explode("@", $unsplitItems); foreach ($files as $file) { if(strlen($file)) { echo "<li>$file</li>"; } } Any idea how I can split my records and display all the items in the array as individual entries?

  • Multiuser's impact on Access Database

    - by SilentRage47
    Can someone explain to me how are effected the performances of an Access 2003 DB when it's used by a lot (30) of users on the same LAN? I'm working on a vb6 project with this access 2003 DB wich performs ok on my local PC, but it's terrible when used across 20-30 users. It's there something I can do to improve performance? How can I understand what's the cause of this degradation in performance?

  • Online DATAFILE MOVE in Oracle Database 12c

    - by Ulrike Schwinn (DBA Community)
    Einige Operationen im Datenbankumfeld können nicht nur offline sondern auch online durchgeführt werden. Ein wichtiges Kennzeichen einer Online Operation ist dabei, dass Abfragen und DML Operationen während des Ablaufs der Operation (beispielsweise einer Reorganisation) ohne Unterbrechung weiter laufen können. Je nach einplanbarer Maintenance Zeit ist es daher durchaus wünschenswert, gewisse Operationen online durchzuführen. Generell gibt es in jedem Datenbankrelease einige Erweiterungen im Umfeld von Online Operationen. Besonders im aktuellen Release 12c gibt es eine Vielzahl neuer Operationen zu diesem Thema.Während der ersten 12c Veranstaltungen fand besonders das Kommando "DATAFILE ONLINE MOVE" besondere Aufmerksamkeit bei vielen Kunden. Aus diesem Grund wird im aktuellen Tipp dazu eine kleine Einführung gegeben.  Mehr dazu erfahren Sie hier.

  • Performance & Security Factors of Symbolic Links

    - by Stoosh
    I am thinking about rolling out a very stripped down version of release management for some PHP apps I have running. Essentially the plan is to store each release in /home/release/1.x etc (exported from a tag in SVN) and then do a symlink to /live_folder and change the document root in the apache config. I don't have a problem with setting all this up (I've actually got it working at the moment), however I'm a developer with just basic knowledge of the server admin side of things. Is there anything I need to be aware of from a security or performance perspective when using this method of release management? Thanks

  • How much faster is a database running in RAM?

    - by orokusaki
    I"m looking to run PostgreSQL in RAM for performance enhancement. The database isn't more than 1GB and shouldn't ever grow to more than 5GB. Is it worth doing? Are there any benchmarks out there? Is it buggy? My second major concern is: How easy is it to back things up when it's running purely in RAM. Is this just like using RAM as tier 1 HD, or is it much more complicated?

  • MySQL Access in Php to a database created in C-Panel

    - by Rhys Drury
    Basically, i'm having trouble connecting to a mysql database using a php web page. I created the database in C-panel using the wizard i'm connecting like this $db_host = "localhost"; //your host Database address $db_username = "xxxx"; //your account username $db_pass = "xxxxx"; //your account password $db_name = "xxxxx"; //your database name @mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql"); @mysql_select_db("$db_name") or die ("no database"); But all my page seems to do is trigger the " could not connect to mysql" my page does have wordpress installed at the minute but I'm planning to get rid of it as I'm creating my site myself. I'm just baffled why it can't connect, because in Phpmyadmin ( a feature on C-panel) it says the database is in localhost.

  • Which would be better? Storing/access data in a local text file, or in a database?

    - by TerranRich
    Basically, I'm still working on a puzzle-related website (micro-site really), and I'm making a tool that lets you input a word pattern (e.g. "r??n") and get all the matching words (in this case: rain, rein, ruin, etc.). Should I store the words in local text files (such as words5.txt, which would have a return-delimited list of 5-letter words), or in a database (such as the table Words5, which would again store 5-letter words)? I'm looking at the problem in terms of data retrieval speeds and CPU server load. I could definitely try it both ways and record the times taken for several runs with both methods, but I'd rather hear it from people who might have had experience with this. Which method is generally better overall?

  • Security considerations when giving access to SQL Server db for a web application

    - by rem
    I need to expose our SQL Server 2008 database for an access from a asp.net web application. This is a new task for me, so I would like to know what basic security requirements are there for configuring software and hardware components of web server and DB Server. Is it OK to have both Web Server (Windows Server 2008) with IIS holding ASP.NET application and SQL Server 2008 on the same machine? Should I have to install additional firewall, like Forefront TMG? Should it be on separate computer? In case a web application is hosted on an external web hosting privider server and SQL Server DB on a our internal server what are "pro's" and "con's" of such configuration?

  • Preventing users from deleting SQL data

    - by me2011
    We just purchased a program that requires the users to have an account in the MS SQL server, with read/write access to the program's database. My concern is that since these users will now have write access to the database, they could directly connect to the SQL server outside of the program's client and then mess with the data directly in the tables. Is there anyway I can prevent access to the database while still allowing access via the client program?

  • Would you store binary data in database or in file system?

    - by paul
    This is a question which has been asked before (large-text-and-images-in-sql) but mainly for data which will be changed. In my case the data will be stored and never changed. Just seems sensible to keep everything together. Are there any reasons why I should not store static binary data in a database? Assuming it is a sensible thing to do, are there any advantages to storing such data in separate tables? (You might begin to realise now that I'm not a DB expert...) Clarify: There will probably be no more than 10-20 users but these will be in the US and in the UK. The binary data will have to be transfered in any case.

  • How can I load a SQLITE database from a buffer with the C API ?

    - by rockeye
    Hello, I am trying to load a database from the memory instead of opening a .sqlite file. I have read the C/C++ API reference but I can not find the proper method. The buffer I am trying to load is simply an sqlite file loaded in memory. I just want to use this buffer (a const char* array) without using the filesystem (I could have saved this buffer in a file, then load the file, but no). First, I create a memory DB : mErrorCode = sqlite3_open_v2(":memory:", &mSqlDatabase, lMode, NULL); This returns SQLITE_OK, then I tried to use the buffer as a statement and call preparev2(MyDB, MyBufferData, MyBufferLength, MyStatement, NULL) but it's not really a statement, and it returns an error. Same result if I call directly exec(MyDB, MyBufferData, NULL, NULL, NULL); I guess there is an appropriate method to achieve this as it might be common to load a DB from a stream or from decrypted data... Thanks.
