  • Live from ODTUG - Big Data and SQL session #2

    - by Jean-Pierre Dijcks
    Sitting in Dominic Delmolino's session at ODTUG (KScope 12). If the session count at conferences is any indication then we will see more and more people start to deploy MapReduce in the database. And yes, that would be with SQL and PL/SQL first and foremost. Both Dominic and our own Bryn Llewellyn are doing MapReduce in the database presentations.  Since I have seen both, I would advice people to first look through Dominic's session to get a good grasp on what mappers do and what reducers do, then dive into Bryn's for a bunch of PL/SQL example. The thing I like about Dominic's is the last slide (a recursive WITH statement) to do this in SQL... Now I am hoping that next year we will see tools vendors show off how they work with Hadoop and MapReduce (at least talking about the concepts!!).

  • My first Windows Phone 7 App: Getting SharePoint Content

    Earlier this week at the Mix10 conference, Microsoft announced the developer story of the Windows Phone 7 Series. As expected, its all about Silverlight! For all the details I highly recommend to watch the recorded keynotes (day 1, day 2). Tonight I could resist trying to build my very first Windows Phone 7 application; the traditional Hello World thingy. Because the developer tools (Visual Studio 2010 and the free Visual Studio 2010 Express) have pretty nice templates, that wasnt much of a challenge....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Is Python worth learning? Is it a useful tool? [closed]

    - by Kenneth
    I recently had a discussion with a professor of mine on the topic of web development. I had recently decided I would learn python to increase my arsenal of web tools which I mentioned to him at that time. He almost immediately asked why I would waste my time on that. I'm not certain but I think he recently started in on researching and studying web development so he could pick up the web development classes that haven't been taught for a while after the previous professor who taught those classes left. I've heard a lot about python and thought maybe he was mistaken about its usefulness. Is python a useful tool to have? What applications can it be used for? Is it better than other similar alternatives? Does it have useful applications outside of web development as well?

  • 8 Deadly Commands You Should Never Run on Linux

    - by Chris Hoffman
    Linux’s terminal commands are powerful, and Linux won’t ask you for confirmation if you run a command that won’t break your system. It’s not uncommon to see trolls online recommending new Linux users run these commands as a joke. Learning the commands you shouldn’t run can help protect you from trolls while increasing your understanding of how Linux works. This isn’t an exhaustive guide, and the commands here can be remixed in a variety of ways. Note that many of these commands will only be dangerous if they’re prefixed with sudo on Ubuntu – they won’t work otherwise. On other Linux distributions, most commands must be run as root.

  • Why don’t UI frameworks use generics?

    - by romkyns
    One way of looking at type safety is that it adds automatic tests all over your code that stop some things breaking in some ways. One of the tools that helps this in .NET is generics. However, both WinForms and WPF are generics-free. There is no ListBox<T> control, for example, which could only show items of the specified type. Such controls invariably operate on object instead. Why are generics and not popular with UI framework developers?

  • Strategies for browser compatibility on web applications in a corporate environment

    - by TiagoBrenck
    With the new CSS 3 and HTML 5 technology, web applications have gained a lot of new tools for a better UI (user interface) interaction, beautiful templates and even responsive layout to fit into tablets and smartphones. Within a corporate environment, those new technologies are required so the company can "follow" the IT evolution and their concurrent, but they also want that those new web applications supports old browsers. How should I deal with this situation? By one side we are asked to follow the the evolution of technology, create responsive layouts and use a lot of cool jQuery plugins. On the other hand, we are asked to support old browsers that do not support those new responsive features, plugins or components. I would like advice and strategies on how to create "modern" web applications that are also supported on old browsers. How does your company deal with this situation? Is it possible to have the same web application run well and beautifully on old browsers, and be responsive and interactive on newer browsers?

  • Connecting Windows 7 to legacy Linux Samba share

    - by bconlon
    I have had to rebuild my Windows 7 PC and all has gone fairly well until I tried to connect to a Samba share on a legacy Linux box running Redhat 8. No matter what combination of domain / user /password I would just see the same message of: "The specified network password is not correct." This is a misleading error, very annoying and a little confusing until I found a hint that Windows 7 default authentication was not supported on older Samba implementations. I guess I figured this out once before as it used to work before the rebuild! Anyway here is the solution: 1. Control Panel->System and Security->Administrative Tools->Local Security Policy (or run secpol.msc). 2. Select Local Policies->Security Options->Network security: LAN Manager authentication level. 3. Select 'Send LM and NTLM - use NTLMv2 session security if negotiated' and click OK. #

  • Getting many files from a SharePoint Document Library the easy way

    - by Stacy Vicknair
    As an individual who does not use Internet Explorer as their primary browser, there is a great feature that you may never notice that allows you to easily copy files to and from a document library: the Open in Windows Explorer link. In browsers such as Chrome or Firefox this link may not appear. I know this isn’t a major groundbreaking feature, but it’s really easy to overlook and it’s worth knowing about, especially when you need to create a local copy of a full document library. In this quick blog we’ll go over how to access this feature in both SharePoint 2007 and 2010. First, make sure you are in Internet Explorer. These options may not show in other browsers. In SharePoint 2007, browse to the document library you would like to access then select Actions > Open with Windows Explorer. In SharePoint 2010, browse to the document library you would like to access then select Library Tools > Library > Open with Explorer from the ribbon.

  • Can't ping Ubuntu laptop from my LAN

    - by oskar
    My laptop has Ubuntu 10.10 and is connected to my router with full internet access, yet I can't ping it from other computers on my LAN. I tried the following: I can successfully ping those other computers from my Ubuntu laptop, so I didn't accidentally connect to someone else's network. I can successfully ping my Ubuntu laptop from itself, though I don't know if that means anything. I haven't messed with iptables at all, so it currently doesn't have any rules set that would cause it to reject anything. I made a DHCP reservation for my laptop's MAC address in my router to make sure I was always using the correct IP address. Please note that I am using a "command line only" install of Ubuntu, so I can't use any GUI network config tools. The reason I want to ping it is because I am trying to run an NFS server on the laptop, yet despite correctly setting it up I cannot access the NFS volume on another computer because it isn't even visible on the network right now.

  • Inside Red Gate - Be Reasonable!

    - by Simon Cooper
    As I discussed in my previous posts, divisions and project teams within Red Gate are allowed a lot of autonomy to manage themselves. It's not just the teams though, there's an awful lot of freedom given to individual employees within the company as well. Reasonableness How Red Gate treats it's employees is embodied in the phrase 'You will be reasonable with us, and we will be reasonable with you'. As an employee, you are trusted to do your job to the best of you ability. There's no one looking over your shoulder, no one clocking you in and out each day. Everyone is working at the company because they want to, and one of the core ideas of Red Gate is that the company exists to 'let people do the best work of their lives'. Everything is geared towards that. To help you do your job, office services and the IT department are there. If you need something to help you work better (a third or fourth monitor, footrests, or a new keyboard) then ask people in Information Systems (IS) or Office Services and you will be given it, no questions asked. Everyone has administrator access to their own machines, and you can install whatever you want on it. If there's a particular bit of software you need, then ask IS and they will buy it. As an example, last year I wanted to replace my main hard drive with an SSD; I had a summer job at school working in a computer repair shop, so knew what to do. I went to IS and asked for 'an SSD, a SATA cable, and a screwdriver'. And I got it there and then, even the screwdriver. Awesome. I screwed it in myself, copied all my main drive files across, and I was good to go. Of course, if you're not happy doing that yourself, then IS will sort it all out for you, no problems. If you need something that the company doesn't have (say, a book off Amazon, or you need some specifications printing off & bound), then everyone has a expense limit of £100 that you can use without any sign-off needed from your managers. If you need a company credit card for whatever reason, then you can get it. This freedom extends to working hours and holiday; you're expected to be in the office 11am-3pm each day, but outside those times you can work whenever you want. If you need a half-day holiday on a days notice, or even the same day, then you'll get it, unless there's a good reason you're needed that day. If you need to work from home for a day or so for whatever reason, then you can. If it's reasonable, then it's allowed. Trust issues? A lot of trust, and a lot of leeway, is given to all the people in Red Gate. Everyone is expected to work hard, do their jobs to the best of their ability, and there will be a minimum of bureaucratic obstacles that stop you doing your work. What happens if you abuse this trust? Well, an example is company trip expenses. You're free to expense what you like; food, drink, transport, etc, but if you expenses are not reasonable, then you will never travel with the company again. Simple as that. Everyone knows when they're abusing the system, so simply don't do it. Along with reasonableness, another phrase used is 'Don't be a ***'. If you act like a ***, and abuse any of the trust placed in you, even if you're the best tester, salesperson, dev, or manager in the company, then you won't be a part of the company any more. From what I know about other companies, employee trust is highly variable between companies, all the way up to CCTV trained on employee's monitors. As a dev, I want to produce well-written & useful code that solves people's problems. Being able to get whatever I need - install whatever tools I need, get time off when I need to, obtain reference books within a day - all let me do my job, and so let Red Gate help other people do their own jobs through the tools we produce. Plus, I don't think I would like working for a company that doesn't allow admin access to your own machine and blocks Facebook!

  • Database .NET

    - by Guilherme Cardoso
    Database .NET is an awesome tool that allow us manage several database in simultaneous (SQL Server, MySQL, Oracle, etc). What lead me to install this tool was an problem that must be shared by must developers. Tools like SQL Server Management Studio consume to many resources, and if you don't have a decent computer you'll get problems in performance, and that's my case! With Database .NET we can access an SQL Server for example, and make several actions to database (crud operations, manage procedures, etc).Of course that this tool can replace the use of SQL Server Management Studio for example!  But it's really usefull if  you just need to perform small operations because it consumes many fewer resources. This tool don't need to be installed (it can be used as an portable application). One tip: if you are using SQL Server Express for example, don't forget to check the server name in Database .NET connection. In my case i've to change from GUILHERM-196634 to GUILHERM-196634\SQLExpress. Project: http://fishcodelib.com/Database.htm Download: http://fishcodelib.com/files/DatabaseNet3.zip

  • Legal Precautions of Customizing Ubuntu LiveCD

    - by Voulnet
    Hello everyone, the organization I work at wants to create a custom Ubuntu LiveCD, the customizations are: Pre-installed programs, plugins, some device drivers, and aesthetics such as icons and backgrounds, as well as changing Firefox's homepage and removing unneeded packages. Not big changes, obviously, and we wish to distribute this custom image for clients to use as a bootable CD or USB stick in order to have a quick environment where all our tools are available instantly. What are the licensing and legal consequences of this? What if some of the programs or plugins that are to be pre-packaged are not GPL'd? I should finally note that we are not changing any code in the kernel or any other distro component. Thank you for your time!

  • How to find data usage of a user on my website?

    - by Dharmik
    I have a website (project) where users get logged in, do their work and then they log out. I need to build a report that displays how much each person has used of data. (bandwidth, how much was downloaded in Kb, etc) So the process may be like counting start of usage from user login to user logout. I have seen a little about Webalizer and AWStats for something like this, But I am not sure how they work. I have tried Content-Length but some pages don't send content-length.I have also seen mod_bandwidth but still I am little confused. This process is needed for my site because now, our company is thinking of charging per usage and also bandwidth allocation for each users (according to their membership). I haven't worked with this type of tools, I am newbie in this matter. I have done only simple websites not any setting like this in Apache or Linux. My project is in Codeigniter.

  • Ask the Readers: Are You A Second Screen Multi-tasker?

    - by Jason Fitzpatrick
    Television watchers are no longer keeping their eyes continuously glued to the screen–increasingly smartphone, tablet, and laptop users have merged their mobile device and television time. Are you one of the second screen multi-taskers? Image courtesy of Umani, a TV-companion application for iPad. According to Nielsen user surveys, at least 80% of mobile device owners have used their device while watching television in the past month–27% said they use their mobile device alongside the television multiple times a day. What the survey results are light on, however, is an in depth look at what the users are doing with their second screen. This week we want to hear about whether or not you’re one of the second screen multi-taskers and what you use your mobile device for during your television/movie time. Sound off in the comments and then check back in on Friday for the What You Said roundup.
