  • How should I architect a personal schedule manager that runs 24/7?

    - by Crawford Comeaux
    I've developed an ADHD management system for myself that's attempting to change multiple habits at once. I know this is counter to conventional wisdom, but I've tried the conventional for years & am now trying it my way. (just wanted to say that to try and prevent it from distracting people from the actual question) Anyway, I'd like to write something to run on a remote server that monitors me, helps me build/avoid certain habits, etc. What this amounts to is a system that: runs 24/7 may have multiple independent tasks to run at once may have tasks that require other tasks to run first lets tasks be scheduled by specific time, recurrence (ie. "run every 5 mins"), or interval (ie. "run from 2pm to 3pm") My first naive attempt at this was just a single PHP script scheduled to run every minute by cron (language was chosen in order to use a certain library, but no longer necessary). The logic behind when to run this or that portion of code got hairy pretty quick. So my question is how should I approach this from here? I'm not tied to any one language, though I'm partial to python/javascript. Thoughts: Could be done as a set of scripts that include a scheduling mechanism with one script per bit of logic...but the idea just feels wrong to me. Building it as a daemon could be helpful, but still unsure what to do about dozens of if-else statements for detecting the current time

  • What books should be read to become an excelent software architect.

    - by dev-cu
    I know there are good books to start with, but let's make a short list of 3-5 books, i don't think only one book could help you in the way of becoming a good architect. I read some time ago that an architect takes years to have the knowledge and the ability to make good decisions. Suppose someone has the potential, what is the way? Please, answers with books that doesn't repeat over the same theme, making your learning process widely. One short list per answer. Vote up that you think are the best ones. Thanks.

  • Marking up table joins in the Microstrategy project metadata with the architect tool?

    - by ConcernedOfTunbridgeWells
    Hi, I am evaluating Microstrategy 9.0.1 and attempting to build a prototype metadata layer using its Architect tool. The tool doesn't seem to have any specific means to mark up joins in the way that the editing tools for SSRS data source views or Business Objects universes do. How does this work in Microstrategy - I have never used this before and may be making invalid assumptions based on other systems I have seen. If one does do this with MicroStrategy, how is it done?

  • Is this question too hard for a seasoned C++ architect?

    - by Monomer
    Background Information We're looking to hire a seasoned C++ architect (10+years dev, of which at least 6years must be C++ ) for a high frequency trading platform. Job advert says STL, Boost proficiency is a must with preferences to modern uses of C++. The company I work for is a Fortune 500 IB (aka finance industry), it requires passes in all the standard SHL tests (numeric, vocab, spatial etc) before interviews can commence. Everyone on the team was given the task of coming up with one question to ask the candidates during a written/typed test, please note this is the second test provided to the candidates, the first being Advanced IKM C++ test, done in the offices supervised and without internet access. People passing that do the second test. After roughly 70 candidates, my question has been determined to be statistically the worst performing - aka least number of people attempted it, furthermore even less people were able to give meaningful answers. Please note, the second test is not timed, the candidate can literally take as long as they like (we've had one person take roughly 10.5hrs) My question to SO is this, after SHL and IKM adv c++ tests, backed up with at least 6+ years C++ development experience, is it still ok not to be able to even comment about let alone come up with some loose strategy for solving the following question. The Question There is a class C with methods foo, boo, boo_and_foo and foo_and_boo. Each method takes i,j,k and l clock cycles respectively, where i < j, k < i+j and l < i+j. class C { public: int foo() {...} int boo() {...} int boo_and_foo() {...} int foo_and_boo() {...} }; In code one might write: C c; . . int i = c.foo() + c.boo(); But it would be better to have: int i = c.foo_and_boo(); What changes or techniques could one make to the definition of C, that would allow similar syntax of the original usage, but instead have the compiler generate the latter. Note that foo and boo are not commutative. Possible Solution We were basically looking for an expression templates based approach, and were willing to give marks to anyone who had even hinted or used the phrase or related terminology. We got only two people that used the wording, but weren't able to properly describe how they accomplish the task in detail. We use such techniques all over the place, due to the use of various mathematical operators for matrix and vector based calculations, for example to decide when to use IPP or hand woven implementations at compile time for a particular architecture and many other things. The particular area of software development requires microsecond response times. I believe could/should be able to teach a junior such techniques, but given the assumed caliber of candidates I expected a little more. Is this really a difficult question? Should it be removed? Or are we just not seeing the right candidates?

  • Can I display ads on a site whose domain name includes a trademark?

    - by architect
    I own a domain containing a trademarked word. I don't want to get into trouble with the trademark owner so my plan is to use the domain to display information (wiki-style) about the service the trademark owner provides. My question is whether I can display ads on this website to make money. For example, let's say I own Google.org (Google being a trademark). On this domain I would write about the real Google (history, business etc.) Can I get into trouble for having ads on this page including ones that promote other search engines (Yahoo, Bing, etc.).

  • How to architect Rails site that can be edited while running?

    - by Chris Kimpton
    Hi, I am writing a Rails app that "scrapes/navigates" some other websites and webservices for content. I am using Mechanize and Savon to do the heavylifting. But given the dynamic nature of the web, I'd like to make my calls to these editable by the admin users of the site - rather than requiring me to release a new version of the site. The actual scraping thread happens async to the website, using the daemons gem. My requirements are: Thinking that the scraping/webservice calling code is quite simple, the easiest route is to make the whole class editable by the admins. Keep a history of the scraping code - so that we can fairly easily revert if we introduce a problem. Initially use the code from the file system, but as soon as thats been edited and stored somewhere, to use that code instead. I am thinking my options are: Store the code in the db (with a history table for the old versions) Store the code in a private git repo somewhere and access that for the history/latest versions. I am thinking the git route might be easiest, given its raison d'etre is to track file history... But perhaps there is a gem/plugin that does all this for me, out of the box? Thanks in advance for any tips/advice. ~chris

  • Can I architect a web app so it can be deployed to either the cloud or a dedicated server / VPS ? Ho

    - by CAD bloke
    Is there are an architecture versatile enough that it may be deployed to either a cloud server or to a dedicated (or VPS) server with minimal change? Obviously there would be config changes but I'd rather leave the rest of the app consistent, keeping one maintainable codebase. The app would be ASP.NET &/or ASP.MVC. My dev environment is VS 2010. The cloud may, or may not be, Azure. Dedicated or VPS would be Win Server 2008. Probably. It is not a public-facing web site. The web app I have in mind would be a separate deployment for each client. Some clients would be small-scale, some will prefer the app to run on a local intranet rather than on the web. Other clients may prefer the cloud approach for a black-box solution. The app may run for a few hours or it may run indefinitely, it depends on the client and the project. Other than deployment scenarios the apps would be more or less identical. As you may see from the tags, I'm assuming a message-based architecture is probably the most versatile but I'm also used to being wrong about this stuff. All suggestions and pointers welcome regarding general architectures and also specific solutions.

  • Storing secure keys on Ubuntu web server

    - by Sencha
    I'm running Ubuntu 12.04 Precise with a DUNG (Django, Unix, Nginx & Gunicorn) environment and my app (as well as various config files) is stored in a python virtual environment inside /srv, which the www-data user has access to. The nginx & gunicorn processes are all run as www-data. My web app requires secure credentials which I am storing in an environment.sh file. This file contains various exports and is run using source before the gunicorn processes execute. My concern is the location of the environment.sh file and it's permissions. Will it be okay storing this file inside the /srv folder where the www-data has access to it? Or should it be stored and owned by root somewhere else such as /var/myapp/environment.sh? Also, regarding the www-data user, if any of my web processes (which are run as www-data) are compromised and someone gains access to them, does that mean that the user could potentially read any file on the system, even if they can't write? Including my secure keys?

  • Multiple SSH private keys for the same host

    - by Sencha
    How can I store 2 different private SSH keys for the same host? I have tried 2 entries in /etc/ssh/ssh_config for the same host with the different keys, and I've also tried to put both keys in the same file and referencing it from one hosts setting, however both do not work. More detail: I'm running Ubuntu server (12.04) and I want to connect to GitHub via SSH to download the latest source for my projects. There are multiple projects running on the same server and each project has a GitHub repo with it's own unique deloyment key-pair. So the host is always the same (github.com) but the keys need to be different depending on which repo I'm using. Different /etc/ssh/ssh_config versions I have tried: Host github.com IdentityFile /etc/ssh/my_project_1_github_deploy_key StrictHostKeyChecking no Host github.com IdentityFile /etc/ssh/my_project_2_github_deploy_key StrictHostKeyChecking no and this with both keys in the same file: Host github.com IdentityFile /etc/ssh/my_project_github_deploy_keys StrictHostKeyChecking no I've had no luck with either. Any help would be greatly appreciated!

If you doubt the power to continuity, take a minute to realize that the entire value proposition of hypervisor-style virtualization is centered around it." -- William Vambenepe (tags: oracle otn cloud virtualization) Merv Adrian: Oracle Exadata: a Data Management Tipping Point "In this second version of its newest platform, Oracle not only provides the latest technology in each part of the data-management architecture, but also integrates them under the full control of one vendor, with a unified approach to leveraging the full stack." -- Merv Adrian (tags: oracle exadata database)

    The centerpiece of every OTN Architect Day event is a panel discussion the gathers all of the session speakers togehter to respond to questions from the audience. I generally try to record these discussions, usually by stiking my iPad on top of one of the PA speakers, with mixed results. Fortunately, the A/V tech at the venue for the Los Angeles event, held on October 25, 2012, had the necessary gear to get a good-quality recording of the panel discussion. So starting this week the OTN ArchBeat Podcast will feature a short series of highlights from those discussions. Listen to Part 1: Dude, What's My Role? Members of the Architect Day panel respond to an audience question about what happens to traditional IT roles in a cloud environment.
