  • Help deciding on an area of study for a PhD [closed]

    - by ale
    I am going to start a PhD in about 1 year. My undergraduate degree is in computer science and my master's is in artificial intelligence. I want to get ideas about what's going to be hot in say 5 years i.e. what could I spend 3-4 years studying to potentially have expertise that will be applicable to industry and the computing world ? Impossible to answer factually but some ideas and thoughts would be great. I have narrowed my ideas down to AI (yes, even more AI) and information security. AI seems to becoming popular again but security is always a going to be useful. From a career point of view, if I were to stay working in software development then this might actually be the best move but I've always wanted to do a PhD! Many thanks :).

  • I need to create an employee schedule/appointments program, but I don't know how to set it up

    - by robz228
    I work for a gym. I am the programmer, its just me, nobody else! Gets really frustrating when there's nobody to bounce conceptual ideas off of. I'm getting rid of our archaic paper binder systems for tracking appointments and what not. I've made a lot of things successfully already, now I'm trying to tackle the personal training department. What I want: Trainer information and work schedule Appointment booking that can be done by time slot with all available trainers for that time, or by trainer with all available hours for that trainer What I've tried so far: I started with an 'appointments' database, a 'trainers' database, and a 'schedules' database. This became so complicated trying to fit the schedule in that I scrapped it. Does anyone know know the best way to structure the tables for this and how to sort of make them communicate correctly? I don't need specific code, I just need help understand how to make this thing!

  • "Never do in code what you can get the SQL server to do well for you" - Is this a recipe for a bad design?

    - by PhonicUK
    It's an idea I've heard repeated in a handful of places. Some more or less acknowledging that once trying to solve a problem purely in SQL exceeds a certain level of complexity you should indeed be handling it in code. The logic behind the idea is that for the large majority of cases, the database engine will do a better job at finding the most efficient way of completing your task than you could in code. Especially when it comes to things like making the results conditional on operations performed on the data. Arguably with modern engines effectively JIT'ing + caching the compiled version of your query it'd make sense on the surface. The question is whether or not leveraging your database engine in this way is inherently bad design practice (and why). The lines become blurred further when all the logic exists inside the database and you're just hitting it via an ORM.

  • Where is the best and easiest place to store global website settings [migrated]

    - by Darkcat Studios
    I'm just putting together an internal data system for a client, which is ASP.NET VB, backed by an SQL database, on an in-house IIS7.5 dedicated server. I want to store certain global settings, such as the age limit for news articles, admin contacts etc, in a file NOT within the database (i.e. to avoid unnecessary database query's) Where would the best place to store this be? global.asax? app.config? or a custom XML file? how would i import these at runtime? (probably to session variables) ETA: Also - the settings must be editable from within the site, i.e. an admin section i'm yet to build

  • Synchronize Azure SQL (cloud) with Azure SQL Emulator (local)?

    - by Sid
    We have an Azure service (web role) that heavily depends on the database. For offline development/testing, we'd like to have the app+db run offline within the emulators. Running the webrole itself within the emulator is straightforward but doing so for the Azure SQL storage isn't so. What is the simplest way to ensure that the cloud Azure SQL database and the emulator/local Azure SQL database are in sync? We can afford some level of staleness for simplicity of sync operation (meaning it's ok for the local copy to be a few hours stale versus mirroring every write as soon as it happens) Thanks

  • Do I need to do an "apt-get update" after adding a PPA?

    - by Sat93
    After adding a new ppa to the repository, is it necessary to update the whole database? By "whole database" I mean is it necessary to update index's of each and every packege? If it's not necessary, then how can I update only that specific package whose ppa I have just added into the repository. For example, if I add an ppa by typing the following in terminal, sudo add-apt-repository ppa:tiheum/equinox then we normally run the following command after it, sudo apt-get update But how can I update the only package which is associated with the above ppa, instead of updating the whole database.
