  • Run On Sentences in Technical Writing

    - by Sean Noodleson Neilan
    This is just a question to think about. When you write technical documentation and programming comments, do you ever find yourself writing run-on sentences in order to be more precise? Is packing more technical information into one sentence better than creating many little sentences each with a little bit of technical information? I know it's better to have lots of little classes in their own little files. Perhaps this doesn't apply to writing?

  • "Sticky button" configuration under X11/Ubuntu?

    - by John Whitley
    Is there a configuration or app that will enable Sticky-keys like functionality for a pointer button under X11? (On Ubuntu 9.10, FWIW.) To be clear, I'd like a single tap (down/up events) to be treated as a down event, and a following tap to be treated as an up event. Context: I have a trackball with a fourth button that I've mapped to act as horizontal/vertical scroll. This works great. It'd be even better if I didn't have to hold the button down when scrolling.

  • NDC Oslo

    - by Alan Smith
    Originally posted on: http://geekswithblogs.net/asmith/archive/2013/06/14/153136.aspx2013 has been a hectic year for conference presentations so far, NDC in Oslo has been the 6th conference I have attended, and my session there was my 11th conference presentation this year. I have been meaning to make the short trip over from Stockholm to NDC for a few years, and this was the first time I made it. I have heard a lot of great things about the event, and was impressed with the location, the sessions, and most of all the atmosphere around the event boots and during the party on Thursday evening. The session I was delivering was my “Grid Computing with 256 Windows Azure Worker Roles & Kinect” demo, which I have delivered at many events over the past 12 months. The demo went fine. I’m always a little nervous when I try to scale out the application to 256 worker roles, it almost always works well and the application will scale in minutes, but very occasionally there can be a longer delay due to the provisioning process in the Windows Azure data centers. This would not be an issue for many scenarios, but when standing on stage in front of a room full of developers you really want things to run smoothly. A number of people have suggested that I should pre-provision an environment so that it is guaranteed to be there when I run the demo during a session. For me the aim has always been to show the rapid scalability on cloud-based platforms live on stage. Pre-provisioning an environment may make for a more reliable demo but to me that would be cheating, and not half as much fun!

  • Why&rsquo;s Poignant Guide To Ruby

    - by Liam McLennan
    According to Wikipedia, “why the lucky stiff was the persona of an anonymous, but prolific writer, cartoonist, musician, artist, and computer programmer”. He looks a bit like Jack Black. His book, Why’s Poignant Guide to Ruby, is a classic, though it can be hard to find since Why disappeared. If you want to learn the Ruby programming language I highly recommend Why’s Poignant Guide to Ruby. I am including a link here so that others who search for it may find it more easily.

  • Oracle Supply Chain at Pella Showcase, April 24-25, 2012

    - by Stephen Slade
    Nothing promtes a product like a grest customer testimony! For nearly a decade, Pella has been holding these 'open-houses' or Showcases as they are called, to illustrate the utilization of Oracle products in their operations. Building custom windows and doors is not an easy task.  With about a trillion combinations of unique sizes, colors and features availalbe, getting the complex multi-unit custom order wrong can be easy to do. I've been to a few of these Showcases and each time,  continually impressed by the precision, best practices and lean disciplines enacted at Pella. Operations representatives and users at Pella, demonstrate the way in which they use Oracle Supply Chain products to deliver fulfillment excellence. Orders are all custom made and delivered in about a week.  Factory tours are conducted and visitors have a chance to see Oracle in operation on the shop floor, driving informational flow and order accuracy in the 99+% range.  It's a must see for anyone considering expansion of their supply chain footprint.  The event is April 24-25 in Pella Iowa, outside Des Moines.   This year, there is a seperate track for CIOs and executives.

  • Do you have to be good at math to be a good programmer?

    - by Charles Roper
    It seems that conventional wisdom suggests that good programmers are also good at math. Or that the two are somehow intrinsically linked. Many programming books I have read provide many examples that are solutions to math problems, or are somehow related to math as if these examples are what make sense to most people. So the question I would like to float is: do you have to be good at math to be a good programmer?

  • Today I talk about you

    - by BuckWoody
    Some time back I posted a blog entry (mirrored here and here) asking you how you design databases. Out of those responses, my own experience, studies I read, and interviews I conducted, I collected a wealth of data. Thanks for your responses. So what am I going to do with that information? Well, all along I had planned for that to be used today. I am giving a presentation at an event called “TechReady” called “How Your Customers Design Databases”. This is a Microsoft-internal event, where technical professionals like myself, salespeople, and the product team get together to talk about what has been working, what doesn’t, what is coming and hopefully (fingers crossed here) what the product team can do to help us help the SQL Server community. I’ve mentioned before that I teach database design as part of a course I run at the University of Washington. I’m also planning to give a mini-lecture from that series at TechEd 2010, so if you’re coming stop by. I’d love to meet you. So today I talk about you – thanks for the input. I hope you and I can make a difference in the product. Might take a while, but it’s nice to know your voice is being heard.

  • What effects do various drugs have on coding style / productivity? [closed]

    - by codecraft
    Can anyone tell me what the effect of various drugs are on coding style, and if coding on drugs can be more productive, or more fun? Are some types of drugs better suited to certain tasks and phases of software development? And which programming languages are best suited to coding on drugs? It would be great if you could back up your answers by data, probably even code snippets showcasing the effect of the drug experience.

  • Cloud service and IM protocol advice, for a backend to group chat mobile app

    - by Jonathan
    Overview I’m going to develop an app on Android and iOS. It will allow users to set up group ‘chat rooms’ and talk on chat rooms set up by other users. The service needs to be highly scalable, such that it could accommodate a massive increase in users overnight (we can only dream). Chat requirements The chat protocol used should be flexible: it should allow me to determine who can view/post on ‘chat rooms’ based on certain other factors, as determined by the first poster/creator of the particular ‘chat room’. It should also allow for users to simply install the app and begin using the service, after only providing a simple nickname (which could be changed later). Chat protocol plans Having looked around I think the XMPP protocol is the best candidate. In particular the Multi-user chat extension looks like what I’ll need. Would this be most suited to my requirements, or do you know another potential solution? Cloud service I have been deciding between Amazon Web Services, Google App Engine and Windows Azure. I’m coming to the conclusion that Azure will be best, as it is easier to manage than AWS (ease of scalability will be a key factor in the design), I think it may be less restricted than GAE, plus Azure will soon have toolkits to allow easy interfacing with both Android and iOS phones. Is this the decision you would have made, or would you recommend/look into other cloud services? General project philosophy I have only recently started looking into this project’s feasibility, and am no expert on any of its aspects. So wherever possible I will leave the actual implementations to experts, i.e. choosing a higher-level cloud service, using a well-documented plugin of a, proven reliable, group chat protocol etc. My background I have some programming knowledge from a computer science degree. Main languages I’ve used have been Java and Python, but I don’t want this to affect design decisions for the project. The most appropriate languages for the task should be used, i.e. I don’t mind learning a lot of new skills (my current programming levels are relatively basic anyway). Thank you Thanks for reading, and any advice you have about any aspect would be greatly appreciated :-)

  • Replicating EFS encrypted files

    - by floyd
    Recently I attempted to configure Microsoft's DFSR on Windows 2008 R2 to replicate a folder which was encrypted with EFS. The setup gave no errors or warnings, but later I read that DFSR does not support EFS in any way. There were also event logs in the DFSR event log indicating an encrypted file was found and wont be replicated. http://technet.microsoft.com/en-us/library/cc773238(v=ws.10).aspx#BKMK_052 My question is, are there any tools that would allow this to occur? Software based preferably.This would be replicating over LAN to destination node for two servers on the same domain.

  • Hypertransport sync flood error

    - by Carl B
    What is it? And what causes it? Is it only for uncorrectable DIMM Errors(Troubleshooting DIMM errors)? When an UCE occurs, the memory controller causes an immediate reboot of the system. During reboot, the BIOS checks the Machine Check registers and determines that the previous reboot was due to an UCE, then reports this in POST after the memtest stage: A Hypertransport Sync Flood occurred on last boot 3 BIOS reports this event in the service processor’s system event log (SEL) as shown in the sample IPMItool output There are what seems to be some suggested answers to include Bad Caps Bios verisons (happens in one version not the other) Graphics card issues Lack of power to the CPU The list of possible generators seems to target everything but the computer case.

  • Does the HTMLEditor control raise any client-side events?

    - by SAMIR BHOGAYTA
    The HTML Editor has three modes: Design, HTML Text and preview mode. Design mode is in an IFrame. HTML Text is prensented in a TextArea and preview mode is in another Iframe. The code rendered about these three modes is as below. iframe id="editor1_ctl02_ctl00" name="editor1_ctl02_ctl00" marginheight="0" marginwidth="0" frameborder="0" src="javascript:false;" style="height:100%;width:100%;display:none;border-width:0px;" /iframe textarea id="editor1_ctl02_ctl01" class="ajax__htmleditor_htmlpanel_default" style="height:100%;width:100%;display:none;" /textarea iframe id="editor1_ctl02_ctl02" name="editor1_ctl02_ctl02" marginheight="0" marginwidth="0" frameborder="0" src="javascript:false;" style="height:100%;width:100%;display:none;border-width:0px;" /iframe In design mode, we can use the following JavaScript to append a callback function in onKeypress event. script type="text/javascript" var count = 0; function pageLoad() { $get('editor1_ctl02_ctl00').contentWindow.document.body.onkeypress = function() { count++; $get('cc').innerHTML = "you input " + count + "charactors"; }; } /script As a same way, you can append another keypress event on TextArea and preview IFrame.

  • What can I do to make sure my code gets maintained in a developer light environment?

    - by asjohnson
    I am a contract data analyst, so I bounce between jobs every 3-6 months, which I find to be a good fit for me, but it leads to some problems when it comes to coding. I mostly do statistics (I've asked a similar question on cross validated, but the answers there are not relevant here), but I have also found out that the business world loves excel and loves copying and pasting the same thing over and over again even more. This led me to learn how to write VBA scripts and then VB.NET programs to automate as many of these reports as I can. I am certain my programs are not the most elegant, but I put a good bit of effort into making sure they work under as many cases as I can test, I add in exceptions and try to code so the program can handle changes in the files that it processes, but there is a limit, if you remove a huge portion of the data, there is a good chance my program is going to trip up, which I accept will inevitably happen. Usually a pretty minor change in the code fixes the problem and I do try and comment my code and make it readable under the assumption that some other person will have to read it some day. My problem is that I generally get put on teams of folks with essentially no experience with programming (like VBA would be a huge stretch for anyone I work directly with). I am wondering what I should be doing as the person that wrote the code to do my best to keep it maintained. I have two approaches in mind (outlined next), but would be very happy to get any advice. Solution 1: Find the more tech savvy coworkers and run them through the programs and what basic changes can be made. Honestly automating excel is about as easy as it can get when it comes to programming, so I feel like I could teach someone the basics of maintaining it pretty quick. Solution 2: Get in touch with the IT department and show them what is going on and maybe they will be able to help. The problem here is that the IT department is constantly swamped (as I'm sure many of you know) and I feel like kind of a jerk for dumping more things on them. I do leave my personal email address with places and am willing to answer quick questions via email, but I view the need for more exhaustive maintenance as something of an inevitability and would like to make sure I do my due diligence to make sure it gets done. I imagine some combination of the two approaches outlined there, but is there any kind of heads up I should give IT? I feel like I would be annoyed if I started getting requests to fix a program that I had never seen from some random guy that is no longer there.

  • SBSMonitoring.mdf reached limit

Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. CREATE DATABASE or ALTER DATABASE failed because the resulting cumulative database size would exceed your licensed limit of 4096 MB per database.

  • Isn't MVC anti OOP?

    - by m3th0dman
    The main idea behind OOP is to unify data and behavior in a single entity - the object. In procedural programming there is data and separately algorithms modifying the data. In the Model-View-Controller pattern the data and the logic/algorithms are placed in distinct entities, the model and the controller respectively. In an equivalent OOP approach shouldn't the model and the controller be placed in the same logical entity?

  • Windows DHCP Server - get notification when a non-AD joined device gets an IP address

    - by TheCleaner
    SCENARIO To simplify this down to it's easiest example: I have a Windows 2008 R2 standard DC with the DHCP server role. It hands out IPs via various IPv4 scopes, no problem there. WHAT I'D LIKE I would like a way to create a notification/eventlog entry/similar whenever a device gets a DHCP address lease and that device IS NOT a domain joined computer in Active Directory. It doesn't matter to me whether it is custom Powershell, etc. Bottom line = I'd like a way to know when non-domain devices are on the network without using 802.1X at the moment. I know this won't account for static IP devices. I do have monitoring software that will scan the network and find devices, but it isn't quite this granular in detail. RESEARCH DONE/OPTIONS CONSIDERED I don't see any such possibilities with the built in logging. Yes, I'm aware of 802.1X and have the ability to implement it long-term at this location but we are some time away from a project like that, and while that would solve network authentication issues, this is still helpful to me outside of 802.1X goals. I've looked around for some script bits, etc. that might prove useful but the things I'm finding lead me to believe that my google-fu is failing me at the moment. I believe the below logic is sound (assuming there isn't some existing solution): Device receives DHCP address Event log entry is recorded (event ID 10 in the DHCP audit log should work (since a new lease is what I'd be most interested in, not renewals): http://technet.microsoft.com/en-us/library/dd759178.aspx) At this point a script of some kind would probably have to take over for the remaining "STEPS" below. Somehow query this DHCP log for these event ID 10's (I would love push, but I'm guessing pull is the only recourse here) Parse the query for the name of the device being assigned the new lease Query AD for the device's name IF not found in AD, send a notification email If anyone has any ideas on how to properly do this, I'd really appreciate it. I'm not looking for a "gimme the codez" but would love to know if there are alternatives to the above list or if I'm not thinking clear and another method exists for gathering this information. If you have code snippets/PS commands you'd like to share to help accomplish this, all the better.

  • Software design of a browser-based strategic MMO game

    - by Mehran
    I wonder if there are any known tested software designs for Travian-like browser-based strategic MMO games? I mean how would they implement the server of such games or what is stored in database and what is stored in RAM? Is the state of the world stored in one piece or is it distributed among a number of storage? Does anyone know a resource to study the problems and solutions of creating such games? [UPDATE] Suggested in comments, I'm going to give an example how would I design such a project. Even though I'm not sure if I'm proposing the right one. Having stored the world state in a MongoDB, I would implement an event collection in which all the changes to the world will register. Changes that are meant to happen in the future will come with an action date set to the future and those that are to be carried out immediately will be set to now. Having this datastore as the central point of the system, players will issue their actions as events inserted in datastore. At the other end of the system, I'll have a constant-running software taking out events out of the datastore which are due to be carried out and not done yet. Executing an event means apply some update on the world's state and thus the datastore. As scalable as this design sounds, I'm not sure if it will be worth implementing. For one, it is pointless to cache the datastore as most of updates happen once without any follow ups. For instance if you have the growth of resources in your game, you'll be updating the whole world state periodically in which case, having incorporated a cache, you are keeping the whole world in RAM (which most likely is impossible). So can someone come up with a better design?
