  • 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?

  • As a programmer, what are some telltale signs that you're about to get fired or laid off?

    - by plaureano
    If you have ever been fired from a job, did you notice anything different about the behavior of your peers or upper management just before your termination? What are some common signs to look for among your coworkers and project manager(s) that would indicate your position is severely at risk? EDIT: My instincts were right, and I opted to resign rather than face termination. I guess when you have that "gut feeling" that something is about to happen, it's a strong sign that you should be heading for the exit...

  • Faster code with another compiler

    - by Andrei
    I'm using the standard gcc compiler in math software development with C-language. I don't know that much about compilers or compiler options, and I was just wondering, is it possible to make faster executables using another compiler or choosing better options? The default Makefile sets options -ffast-math and -O3 and I think both of them have some impact in the overall calculation time. My software is using memory quite extensively, so I imagine some options related to memory management might do the trick? Any ideas?

  • Restrict second screen to certain window/application

    - by Daniel Hepper
    I have a system with two screens. On the primary screen, I want to use Windows in a normal way. On the secondary screen, I want to display a window of a certain application and nothing else. In no case should anything else than this specific window show up on the secondary screen: no other applications, no dialog boxes. If possible, I want to restrict the mouse pointer to the primary screen as well. I tried UltraMon, but I think my requirements go beyond its features. Any ideas?

  • Hardest concept to grasp as a beginner

    - by noizetoys
    When you were starting to program, what was the hardest concept for you to grasp? Was it recursion, pointers, linked lists, assignments, memory management? I was wondering what gave you headaches and how you overcame this issue and learned to love the bomb, I mean understand it. EDIT: As a followup, what helped you grok your hard-to-grasp concept?

  • Semantic #region usage

    - by Luca
    What's your opinion about using #region folding using application semantic, instead of folding for "syntax". For example: #region Application Loop #region User Management #region This Kinf of stuffs instead of #region Private Routines #region Public Properties #region ThisRoutine // (Yes, I've seen this also!) In this logic, I'm starting fold even routine bodies. I'm starting to love #region directive (even using #pragma region when using C++!).

  • Best Linux Distro for web services (Nginx & node.js) on laptop: Compaq 6710b?

    - by tomByrer
    I haven't used Linux in 5+ years, aside from d/l occasional system recovery CDs off DistroWatch, so I don't know the current landscape. Related postings on this forum are several years old & may not relate to my hardware (Compaq 6710b laptop, Core2Duo Centrino). Requirements: Use the Compaq 6710b laptop's WiFi out of the box enough frequently updated pre-made packages for web hosting & development (Nginx & node.js are biggest concerns, everyone has Apache & PHP, & I'm not crazy about building from source) prefer be easy enough to use, but outside help available (so a small user-base distro is only OK if the community is active & a major disto's packages are compatable) configuration easy to transfer to outside web hosts. You have actually installed/used recommended disto (don't have to be expert) TIA!

  • Backup software for Ubuntu - which one?

    - by Industrial
    Hi everybody, I have spent some time testing out different backup solutions for my small home office during the last weeks, but still haven't found anything that have been working out too well yet. We can definitely work with a non-GUI script if that's what it takes, if only the requirements are fulfilled: Upload to Amazon S3 Europe. We get unbelievable slow uploading speed to US, so uploading 400+ GB of data will not be happening anytime this year... Incremental backups - only changed files shall be uploaded or we will have a big bill from Amazon in the end of each month.. Files should not be uploaded in one big per-folder archive. This is not efficient at all, since if we change one file in a subfolder, a huge two-digit GB sized file would have to be uploaded during next backup. Not good for economy again, or traffic overhead on our internet connection. What options are available to us? Thanks!

  • How optimize queries with fully qualified names in t-sql?

    - by tomaszs
    Whe I call: select * from Database.dbo.Table where NAME = 'cat' It takes: 200 ms And when I change database to Database in Management Studio and call it without fully qualified name it's much faster: select * from Table where NAME = 'cat' It takes: 17 ms Is there any way to make fully qualified queries faster without changing database?

  • Customising Windows 8 Start Screen Tiles

    - by Joe Taylor
    We are looking for an effective way to manage the start screen in Windows 8. So far using WSIM we can add certain start tiles by using the OOBE System - shell setup - SquareTiles and WideTiles properties. However this only seems to work for square tiles and not wide tiles, if anyone has any insight on this it would eb appreciated. However the main question is has anyone managed to modify this screen using a GPO, we can add application shortcuts to the Start menu list on the All Apps page using a create shortcut to all users start menu policy. However as we occasionally deploy apps throughout the year in line with the courses requirements we would want to be able to put a shortcut on the home screen. Is it possible?

  • iPhone Application failing to come back from sigkill

    - by overscore
    I have no idea if this is intended behaviour, but whenever the application exits (say, the user is double-clicking the home button and pressing on the red dash on the icon) I get the dreaded SIGKILL. Now, when I try to launch the app again all I get is the old screen state and a frozen (I presume ?) program. It could be because of clunky memory management, but NSZombieEnabled doesn't seem to agree. Any thoughts ?

  • recommendations for disk -> usb backup software

    - by TWood
    Recently I lost a tape drive and rather than repair the unit I decided that backups to usb external drives would be cheaper. In the past I used NTBackup and figured that the new server 2008 R2 backup wbadmin utility would be able to meet my needs. It does not. I am looking for recommendations for another utility that i can use. My requirements are: -backup local disk in addition to files on a network share -scheduled task integration (or some gui options to manage schedule) -non-incremental backup Basically I could do this all with WBAdmin if it just supported network shares. I saw some links that described attaching a vhd pointed to a network share but I am trying to avoid hacks like that. If i'm going to do all that trouble I'd just as well manually copy the directories over myself. If anyone has any software suggestions that might make this task easier for me let me know please. I am considering BackupAssist but can only find a few reviews here and there for it.

  • When is `x IS NOT NULL` not the same as `NOT(x IS NULL)`

    - by Mark Hurd
    For what x is The expression x IS NOT NULL is not equal to NOT(x IS NULL), as is the case in 2VL (quote from this answer, which is quoting Fabian Pascal Practical Issues in Database Management - A Reference for the Thinking Practitioner -- near the end of that answer) My guess is when x IS NULL is NULL, but I cannot guess when that would be (i.e. I haven't checked the SQL standard).

  • How do I program a hardware button on my laptop?

    - by daniel11
    So I have a set of touch screen buttons on the top of my laptop's keyboard, (one turns on power save mode, one disables/enables the mouse touch pad, one toggles the wifi adapter, and two turns the volume up/down). However there's another one that opened a file backup utility that came with my laptop. Since I bought my laptop, I've uninstalled that utility, rendering this button useless. Would it be possible to reprogram that button to open another file or program on my computer? And if so, what are the requirements and how would I go about doing it? Thanks in advance!

  • C# or windows equivalent of OS X's Core Data?

    - by Nektarios
    I'm late to the boat and have only just now started using Core Data in OS X / Cocoa - it's incredible and is really changing the way I look at things. Is there an equivalent technology in C# or the modern Windows frameworks? i.e. having managed data types where you get saving, data management, deleting, searching all for free? Also wondering if there's anything like this on Linux.

  • Is it a good practice to always use smart pointers ?

    - by Dony Borris
    Hi, I find smart pointers to be a lot more comfortable than raw pointers. So is it a good idea to always use smart pointers? ( Please note that I am from Java background and hence don't much like the idea of explicit memory management. So unless there are some serious performance issues with smart pointers, I'd like to stick with them. ) Any advice would be greatly appreciated. Thanks.

  • 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.

  • EXCEL function working like SQL group by + count(distinct *)?

    - by Solo
    Suppose I have an EXCEL sheet with below data CODE (COL A) | VALUE (COL B) ============================== A01 | 10 A01 | 20 A01 | 30 A01 | 10 B01 | 30 B01 | 30 Is there an EXCEL function working like .. SELECT CODE, count (Distinct *) FROM TABLE GROUP BY CODE CODE | Distinct Count of Value =================================== A01 | 3 B01 | 1 or, better yet, Can we have an excel formula pasted in Column C to get something like this: CODE (COL A) | VALUE (COL B) | DISTINCT VALUE COUNT WITH MATCHING CODE (COL C) =============================================================================== A01 | 10 | 3 A01 | 20 | 3 A01 | 30 | 3 A01 | 10 | 3 B01 | 30 | 1 B01 | 30 | 1 I know I can use pivot table to get this result easily. However due to reporting requirements I have to append the "distinct count" column to the excel sheet, hence pivot table is not an option. My last resort is to use Excel Macro (Which is fine), but before that I would like to learn whether excel functions can accomplish this kind of task. Many thanks!
