  • contractor vs full time employee

    - by Victor
    What is the long term career prospect of a contractor/consultant in IT field vs a full time salaried employee? The usual arguments aside: Stability vs more upfront money;paid leaves vs tax savings;less paperwork vs more freedom;stagnation vs changing job environments etc etc etc Can some one with a long career experience in hopefully both sides of the divide comment on the pros and cons of contracting vs being an employee? This will be beneficial for all if only people with ample experience choose to answer. Comments are always welcome though.

  • Paypal "Subscribe" button: Is it possible to let the subscriber set the amount?

    - by Šime Vidas
    I'm setting up a recurring payment option on my website. I'd like to have two options: Option 1 (for individuals): Fixed $6/mo subscription Option 2 (for organizations): A subscription where the amount is set by the subscriber PayPal's "Subscribe" button does not seem to allow that: When I leave the "Amount" field of the 2nd option empty, I get an error: So, is this not possible? Do all options require fixed amounts?

  • reference list for non-IT driven algorithmic patterns

    - by Quicker
    I am looking for a reference list for non-IT driven algorithmic patterns (which still can be helped with IT implementations of IT). An Example List would be: name; short desc; reference Travelling Salesman; find the shortest possible route on a multiple target path; http://en.wikipedia.org/wiki/Travelling_salesman_problem Ressource Disposition (aka Regulation); Distribute a limited/exceeding input on a given number output receivers based on distribution rules; http://database-programmer.blogspot.de/2010/12/critical-analysis-of-algorithm-sproc.html If there is no such list, but you instantly think of something specific, please 'put it on the desk'. Maybe I can compile something out of the input I get here (actually I am very frustrated as I did not find any such list via research by myself). Details on Scoping: I found it very hard to formulate what I want in a way everything is out that I do not need (which may be the issue why I did not find anything at google). There is a database centric definition for what I am looking for in the section 'Processes' of the second example link. That somehow fits, but the database focus sort of drifts away from the pattern thinking, which I have in mind. So here are my own thoughts around what's in and what's out: I am NOT looking for a foundational algo ref list, which is implemented as basis for any programming language. Eg. the php reference describes substr and strlen. That implements algos, but is not what I am looking for. the problem the algo does address would even exist, if there were no computers (or other IT components) the main focus of the algo is NOT to help other algo's chances are high, that there are implementions of the solution or any workaround without any IT support out there in the world however the algo could be benefitialy implemented/fully supported by a software application = means: the problem of the algo has to be addressed anyway, but running an algo implementation with software automates the process (that is why I posted it on stackoverflow and not somewhere else) typically such algo implementations have more than one input field value and more than one output field value - which implies it could not be implemented as simple function (which is fixed to produce not more than one output value) in a normalized data model often times such algo implementation outputs span accross multiple rows (sometimes multiple tables), whereby the number of output rows depends on the input paraters and rows in the table(s) at start time - which implies that any algo implementation/procedure must interact with a database (read and/or write) I am mainly looking for patterns, not for specific implementations. Example: The Travelling Salesman assumes any coordinates, however it does not say: You need a table targets with fields x and y. - however sometimes descriptions are focussed on examples with specific implementations very much - no worries, as long as the pattern gets clear

  • Computer science [closed]

    - by user73589
    I'm a computer science graduate Information systems department. I graduated this year with GPA 3.8 but I'm totally lost, we didn't work on making applications and writing a lot of codes at college. I feel that if I applied in any job I won't be taken because I don't have any knowledge. I'm a very hardworker but I don't know from where to start and what to do. Should I go for web design and that staff or for Android and mobile applications? What can I do and how to start?

  • Can't read CDs, can't create USB... how do I install Ubuntu?

    - by user68080
    Hello everyone and thank you in advance for your time. I have troubles with the latest Ubuntu distribution: since I upgraded to 12.04 Ubuntu has started having troubles (internal errors, packages that crash repeatedly, I can't install new packages, Ubuntu Software Center crashes, Java apps that worked stopped working and display weird mistakes, files were corrupted... a mess). I ultimately decided to format everything and install 12.04 from scratch. I made a backup and everything, but now I have troubles installing ubuntu 12.04. Specifically, a CD I burned with Brasero that works on another PC is not read by my laptop (not at boot phase, nor inside Ubuntu), and when I try to create a USB with Ubuntu (following the instructions I found on the ubuntu site) Startup Disk Creator stops at 22% saying that "the codes do not match". Any idea on what to do next? No, I can't buy a new PC.

  • Can anyone recommend a good SMS gateway for PHP?

    - by Nick
    I'm looking for an SMS gateway that has the following criteria: Supports sending from short codes Opt-in capabilities for end-user (will require user to opt in before sending message) Has a clean API, preferably an XML/ REST API, although SOAP is fine The cheaper the better Honestly, I keep searching and searching all permutations of "SMS Gateway API" etc... on Google and I can't find any great services that can support all of these criteria. There are a lot of really SEO optimized sites and I can't tell which of them are legit. I'm looking for something that will be easy and quick to implement, and none of my colleagues have any recommendations. What APIs have you used (preferably with PHP) that have gotten this job done? Which services have been the most pleasant to deal with, both technically and support-wise? Update: Will be sending primarily (probably solely) in the US.

  • Encrypt images before uploading to Dropbox [migrated]

    - by Cherry
    I want to encrypt a file first before the file will be uploaded to the dropbox. So i have implement the encryption inside the uploading of the codes. However, there is an error after i integrate the codes together. Where did my mistake go wrong? Error at putFileOverwriteRequest and it says The method putFileOverwriteRequest(String, InputStream, long, ProgressListener) in the type DropboxAPI is not applicable for the arguments (String, FileOutputStream, long, new ProgressListener(){}) Another problem is that this FileOutputStream fis = new FileOutputStream(new File("dont know what to put in this field")); i do not know where to put the file so that after i read the file, it will call the path and then upload to the Dropbox. Anyone is kind to help me in this? As time is running out for me and i still cant solve the problem. Thank you in advance.

    Hi! I am implementing ToolTip in Java as to make users having an easier time to use the product.

Anyone got any expertise within the field that know how to avoid this problem? Cheers, Skarion

  • Wordpress Multisite (Subfolders) - Google Analytics Tracking

    - by mmundiff
    I have a Wordpress multisite subfolder instance that I would like to track via Google Analytics. I guess optimally this would be a plugin which I could track each site in two places The Main Tracking Code which totals all traffic from the Multisite instance The Individual Site tracking code to see how each site specifically is doing. I think this plugin would have worked for me if I had a subdomain multisite instance: http://wordpress.org/extend/plugins/google-analytics-multisite-async/installation/ I know I can manually place the dual tracking code (http://www.markinns.com/articles/full/adding_two_google_analytics_accounts_to_one_page) but that would involve editing a theme and I have multiple sites using TwentyEleven template. I don't think I can edit the theme and not have it wreak havoc on the rest of the sites using TwentyEleven. So has anyone done this? Is there a a technique I'm missing? Is there a plugin available to do this in Multisite Subfolder installations? Is there a way to manually insert GA codes into themes which are used by multiple sites? Any insight is appreciated.

  • If you had to teach professional development to students that just graduated school, what would be the topics?

    - by user2567
    The idea is to give them more chances to be efficient in a professional environment. Most students are good with theory, most of them are smart, but they have to learn how to solve common technical problems. They will be better programmers as they practice, but maybe we can help them with some introduction training. Which topics you would select for a two weeks full time training? It's an open question, I don't want to suggest things that will reduce the answers to a particular field.

  • What should a Python developer know while learning Ruby?

    - by C J
    I have been a Python programmer for about 18 months, consisting of one internship and a few side projects, and I consider myself pretty comfortable in the language. However, there seems to be a lot of attention on Ruby in the programming field, but not a lot on Python anymore. So in learning Ruby, are there going to be Pythonic things that are just bad practices in Ruby? What should I watch out for, and what should I avoid?

  • Would SQL certification be a good idea to compensate for a gap in experience?

    - by SK9
    I have a couple of years of experience with SQL Server, mostly basic tasks of writing queries and stored procedures, but have not been employed for a number of years (getting my masters in a totally unrelated field). I've been applying for months and no prospects yet as it seems most companies are worried about the gap in my employment. Do you think it would be worthwhile to get a SQL certification? I'd really appreciate your insights since I truly don't know what to do. Thanks!

  • How to incoporate Taiwan into ISO 3166-1?

    - by Misha
    I received a rather heartfelt e-mail from a user on our site explaining that Taiwan wasn't a province of China and that they wouldn't register until this was changed. Our site is made from a dozen or so valued contributors so we are going to change it. See issue here: http://www.iso.org/iso/country_codes/iso_3166-faqs/iso_3166_faqs_specific.htm. I found the lines to edit in my CMS, but we have valued users from both China and Taiwan. I was wondering the most politically neutral way to amend my country codes. What should the entries for China and Taiwan say?
