  • Copying an sqlite database from file to :memory using C#

    - by davidb
    I have a small database with tables containing a small amount of data which I need to copy into memory. Currently I am using: insertcommand.CommandText = "SELECT sql FROM sqlite_master WHERE sql NOT NULL;"; To pull all the table schema from the file database, however I'm not really sure how to proceed with creating these tables in the new memory database, and copying all the relevant data across. In short, how do I copy an SQLite database from file to memory using C# and System.Data.SQLite?

  • How to pick a great working team?

    - by Javierfdr
    I've just finished my master and I'm starting to dig into the laboral world, i.e. learning how programming teams and technology companies work in the real world. I'm starting to design the idea of my own service or product based on free software, and I will require a well coupled, enthusiast and fluid team to build and the idea. My problem is that I'm not sure which would be the best skills to ask for a programming team of 4-5 members. I have many friends and acquaintances, with whom I've worked during my studies. Must of those ones I have in mind are very capable and smart people, with a good logic and programming base, although some of them have some characteristics that I believe that could influtiate negatively in the group: lack of communication, fear to debate ideas, hard to give when debating, lack of structured programming (testing, good commenting, previous design and analysis). Some of them have this negative characteristics, but must of them have a lot of enthusiasm, nice working skills (from an individual point of view), and ability to see the whole picture. The question is: how to pick the best team for a large scale project, with a lot of programming? Which of these negative skills do you think are just too influential? Which can be softened with good leadership? Wich good skills are to be expected? And any other opinion about social and programming skills of a programming team.

  • Database Mirroring of SQL server

    - by jbp117
    I have two databases that are mirrored to another server using database mirroring. The mirror server has to be down for some reason for few days. Now the production server is having principal databases in (PRINCIPAL/DISCONNECTED) State. Clients can access those databases. So what happens when they keep on adding data to these databases?? Will the data get committed or waits till the mirror comes up?

  • MS Access split database queries

    - by Lance Roberts
    When the frontend of a MS Access db queries a MS Access backend on another machine over the network, does it pull in the whole table/database/file, or does it have some way of extracting just what it needs from the backend, thereby lessening network load.

  • One Database vs. Multiple Databases

    - by Ricardo
    I need to design a system which represents multiple "projects", one per client in SQL Server , something similar to StackExchange... same data model, different sites (one per customer). Each project has the same data model, but is independent of all others. My inclination is to use one database to store all projects. What is your recommendation?

  • Optimal disk partitions for database setup (15 Drives)

    - by Jason
    We are setting up a new database system and have 15 drives to play with (+2 on-board for the OS). With a total of 15 drives would it be better to setup all 14 as one RAID-10 block (+1 hot spare) OR split into two RAID-10 sets one for Data (8 disks) and one for logs/backups (6 disks). My question boils down to the following: is there a specific point where having more drives in a RAID-10 setup will out preform having the drives broken into smaller RAID-10 sets.

  • Efficient way to secure tomcat database connections

    - by Greymeister
    Our customer has a problem with database information in plaintext within a server.xml or context.xml file on the Tomcat server. I've looked at several sites like OWASP and it seems like there's no obvious solution. I've also seen things like this wordpress blog which describe implementing a custom Tomcat extension to do this. There must exist some standard implementation(s) already without having to roll your own. Does anyone have experience with such a solution?

  • Syncronizing XML file with MySQL database

    - by Fred K
    My company uses an internal management software for storing products. They want to transpose all the products in a MySql database so they can do available their products on the company website. Notice: they will continue to use their own internal software. This software can exports all the products in various file format (including XML). The syncronization not have to be in real time, they are satisfied to syncronize the MySql database once a day (late night). Also, each product in their software has one or more images, then I have to do available also the images on the website. Here is an example of an XML export: <?xml version="1.0" encoding="UTF-8"?> <export_management userid="78643"> <product id="1234"> <version>100</version> <insert_date>2013-12-12 00:00:00</insert_date> <warrenty>true</warrenty> <price>139,00</price> <model> <code>324234345</code> <model>Notredame</model> <color>red</color> <size>XL</size> </model> <internal> <color>green</color> <size>S</size> </internal> <options> <s_option>some option</standard_option> <s_option>some option</standard_option> <extra_option>some option</extra> <extra_option>some option</extra> </options> <images> <image> <small>1234_0.jpg</small> </image> <image> <small>1234_1.jpg</small> </image> </images> </product> </export_management> Some ideas for how can I do it? Or if you have better ideas to do that.

  • Language Agnostic Basic Programming Question

    - by Rachel
    This is very basic question from programming point of view but as I am in learning phase, I thought I would better ask this question rather than having a misunderstanding or narrow knowledge about the topic. So do excuse me if somehow I mess it up. Question: Let's say I have class A,B,C and D now class A has some piece of code which I need to have in class B,C and D so I am extending class A in class B, class C, and class D Now how can I access the function of class A in other classes, do I need to create an object of class A and than access the function of class A or as am extending A in other classes than I can internally call the function using this parameter. If possible I would really appreciate if someone can explain this concept with code sample explaining how the logic flows. Note Example in Java, PHP and .Net would be appreciated.

  • Putting data from local SQL database to remote SQL database without remote SQL access enabled (PHP)

    - by Shyam
    Hi, I have a local database, and all the tables are defined. Eventually I need to publish my data remotely, which I can do easily with PHPmyadmin. Problem however is that my remote host doesn't allow remote SQL connections at all, so writing a script that does a mysqldump and run it through a client (which would've been ideal) won't help me here. Since the schema won't change, but the data will, I need some kind of PHP client that works "reverse". My question is if such a client exists and what would be recommended to use (by experience). I just need an one way trip here, from my local database (Rails) to the remote database (supports PHP), preferable as simple and slick as possible. Thank you for your replies, comments and feedback!

  • Dynamic programming - Coin change decision problem?

    - by Tony
    I'm reviewing some old notes from my algorithms course and the dynamic programming problems are seeming a bit tricky to me. I have a problem where we have an unlimited supply of coins, with some denominations x1, x2, ... xn and we want to make change for some value X. We are trying to design a dynamic program to decide whether change for X can be made or not (not minimizing the number of coins, or returning which coins, just true or false). I've done some thinking about this problem, and I can see a recursive method of doing this where it's something like... MakeChange(X, x[1..n this is the coins]) for (int i = 1; i < n; i++) { if ( (X - x[i] ==0) || MakeChange(X - x[i]) ) return true; } return false; Converting this a dynamic program is not coming so easily to me. How might I approach this?

  • Differences & Similarities Between Programming Paradigms

    - by DaveDev
    Hi Guys I've been working as a developer for the past 4 years, with the 4 years previous to that studying software development in college. In my 4 years in the industry I've done some work in VB6 (which was a joke), but most of it has been in C#/ASP.NET. During this time, I've moved from an "object-aware" procedural paradigm to an object-oriented paradigm. Lately I've been curious about other programming paradigms out there, so I thought I'd ask other developers their opinions on the similarities & differences between these paradigms, specifically to OOP? In OOP, I find that there's a strong focus on the relationships and logical interactions between concepts. What are the mind frames you have to be in for the other paradigms? Thanks Dave

  • Why aren't we programming on the GPU???

    - by Chris
    So I finally took the time to learn CUDA and get it installed and configured on my computer and I have to say, I'm quite impressed! Here's how it does rendering the Mandelbrot set at 1280 x 678 pixels on my home PC with a Q6600 and a GeForce 8800GTS (max of 1000 iterations): Maxing out all 4 CPU cores with OpenMP: 2.23 fps Running the same algorithm on my GPU: 104.7 fps And here's how fast I got it to render the whole set at 8192 x 8192 with a max of 1000 iterations: Serial implemetation on my home PC: 81.2 seconds All 4 CPU cores on my home PC (OpenMP): 24.5 seconds 32 processors on my school's super computer (MPI with master-worker): 1.92 seconds My home GPU (CUDA): 0.310 seconds 4 GPUs on my school's super computer (CUDA with static domain decomposition): 0.0547 seconds So here's my question - if we can get such huge speedups by programming the GPU instead of the CPU, why is nobody doing it??? I can think of so many things we could speed up like this, and yet I don't know of many commercial apps that are actually doing it. Also, what kinds of other speedups have you seen by offloading your computations to the GPU?

  • Pair programming tools that are not remote

    - by JonathanTech
    I am currently in a job where we practice serious pair programming on windows machines. We both have a set of keyboards, mice, and we have two monitors, which works well for switching who's the driver really easy, but there are some points in the session that I would like to start writing tests at the same time that my pair is writing implementation. I am wondering if there is any program that would allow me to have effectively two cursors and keyboard focuses on the same computer. If they don't exist then I am willing to experiment with my own solution, but I would like input as to how to best accomplish this. I am most familiar with .Net 3.5 technologies, but I also know Java and am willing to learn C++ to solve this problem. If I was creating the solution myself I would go down the road of being able to grab the input of one hardware device (i.e. a specific mouse that's installed) and prevent Windows from moving the pointer, and instead move my own programs pointer independently.

  • reinventing the wheels: Node.JS/Event-driven programming v.s. Functional Programming?

    - by ivanTheTerrible
    Now there's all the hype lately about Node.JS, an event driven framework using Javascript callbacks. To my limited understanding, its primary advantage seems to be that you don't have to wait step by step sequentially (for example, you can fetch the SQL results, while calling other functions too). So my question is: how is this different, or better than just functional languages, like CL, Haskell, Clojure etc? If not better, then why don't people just do functional languages then (instead of reinventing the wheel with Javascript)? Please note that I have none experience in either Node.JS nor functional programming. So some basic explanation can be helpful.

  • Perl: Event-driven Programming

    - by Shiftbit
    Is there any POSIX signals that I could utilize in my perl program to create event-driven programming? Currently I have multi-process program that is able to cross communicate but my parent thread is only able to listen to listen at one child at a time. foreach (@threads) { sysread(${$_}{'read'}, my $line, 100); chomp($line); print "Parent hears: $line\n"; } The problem is that the parent sits in a continual wait state until it receives it a signal from the first child before it can continue on. I am relying on 'pipe' for my intercommunication. My current solution is very similar to: http://stackoverflow.com/questions/2558098/how-can-i-use-pipe-to-facilitate-interprocess-communication-in-perl If possible I would like to rely on a $SIG{...} event or any non-CPAN solution.

  • chomsky hierarchy and programming languages

    - by dader51
    Hi, I'm trying to learn some aspects of the CH ( chomsky hierarchy ) which are related to PL ( programming languages ), and i still have to read the Dragon Book. I've read that most of the PL can be parsed as CFG ( context free grammar ). In term of computational power, it equals the one of a pushdown non deterministic automaton. Am I right ? If it's true, then how could a CFG holds a UG ( unrestricted grammar, which is turing complete ) ? I'm asking because, even if PL are CFG they are actually used to describe TM (turing machines ) and through UG. I think that's because of at least two different levels of computing, the first, which is the parsing of a CFG focuses on the syntax related to the structure ( representation ? ) of the language, while the other focuses on the semantic ( sense, interpretation of the data itself ? ) related to the capabilities of the pl which is turing complete. Again, are these assumptions rights ? thanx a lot.

  • Programmer productivity by programming language?

    - by Jason Baker
    In code complete, there's a nice table listing how productive a programmer is depending on language. Jeff Atwood has a nice blog post about it. This chart is at least 4 years old by now. I'm curious: have there been any more recent studies done on this? (insert standard anti-flamewar boilerplate here... we're all adults) Update: I appreciate everyone's opinions on the subject and whether or not this is a relevant question or not. But that's not really what I'm asking for. I'm wanting any studies on the subject. I'm inclined to agree with most of the opinions posted thus far, but I'd like to see if there's any research to back that up. And I'm also aware that choice of programming language is a complicated subject that depends on other factors like developer familiarity. To me, this is all the more reason to have these kinds of discussions backed by research. Also, thanks for the link, Robert Gamble.

  • Entitiy Framework: "Update Database from Model" instead of "Generate Database from Model"

    - by David
    Hey everyone, I have created a Entity Framework 4 model with Visual Studio 2010 and generated a database from it. Now I found myself adding new properties (with default values), changing documentation of columns, changing names of columns, changing types of columns several times. All tasks that do not require much "extra work" in order not to be possible to be achieved automatically (in my humble opinion). Everytime I did "Generate Database from Model" and lost of course the table data. Is there a way just to update the database's architecture so to say - leaving the table data untouched? Maybe with some user interaction especially when changing types etc.? Or would this functionality be simply too difficult to be realized to work in a reliable way? Thanks in advance! Cheers, David

  • Seeking Functional Programming Lexicon

    - by Randall Schulz
    Hi, Knowing the argot of a field helps me a lot, especially since it allows me to converse intelligently with those who know a lot more than I, so I would like to find a good lexicon of Functional Programming terms. E.g., I repeatedly encounter these: Functor, Arrow, Category, Kleisli, Monad, Monoid, a veritable zoo of Morphisms, etc. I also notice many of these appear with prefixes such as "covariant", "co-", "endo-" etc. Of these, I can say I actually understand Monoid and Covariant and sort of get Monad, but the rest are still gibberish to me. (Note that I don't mean this list as exhaustive and I'm not looking to have these defined or described for me here, I'm looking for learning resources.) Can someone point me towards an FP lexicon? It need not be on-line, as long as it's possible to find it (and it's not a rare volume for which I'd have to pay many tens of dollars).
