  • Language Design: Are languages like Python and CoffeeScript really more comprehensible?

    - by kittensatplay
    The "Verbally Readable !== Quicker Comprehension" argument on http://ryanflorence.com/2011/case-against-coffeescript/ is really potent and interesting. I and I'm sure others would be very interested in evidence arguing against this. There's clear evidence for this and I believe it. People naturally think in images, not words, so we should be designing languages that aren't similar to human language like English, French, whatever. Being "readable" is quicker comprehension. Most articles on Wikipedia are not readable as they are long, boring, dry, sluggish and very very wordy. Because Wikipedia documents a ton of info, it is not especially helpful when compared to sites with more practical, useful and relevant info. Languages like Python and CoffeScript are "verbally readable" in that they are closer to English syntax. Having programmed firstly and mainly in Python, I'm not so sure this is really a good thing. The second interesting argument is that CoffeeScript is an intermediator, a step between two ends, which may increase the chance of bugs. While CoffeeScript has other practical benefits, this question specifically requests evidence showing support for the counter-case of language "readability"

  • Editing the Microsoft Security Essentials context-menu

    - by GPX
    As all MSE users would know, the context-menu item that it adds to Explorer is really long, with one whole sentence "Scan with Microsoft Security Essentials...". Is there a way to edit this and shorten it? I figured out the the file shellext.dll is responsible for registering the context menu. I used ResEdit to edit the DLL and changed the string table entry from Scan with ($BrandName) to Scan with MSE. But it still won't change. I've also tried de-registering the DLL and then registering it again. No luck! Any ideas? Or am I doing something wrong?

  • Read-only lock on a SharePoint site collection, or Why can't I edit anymore?

    - by PeterBrunone
    Monday morning, the calls started.  For some reason, long-time users were unable to edit list items.  I figured we had a permissions issue, so I popped in to look at the Site Settings -- and found that I couldn't.  A quick trip to Central Administration showed that I was still listed as a Site Collection Administrator, but I had no power at all on the site collection in question.A quick glance at the logs told me that the server had recently shut down unexpectedly (this is a Hyper-V virtual machine).  Apparently, in the confusion, somehow SharePoint decided to lock the site collection as Read Only.  This can be remedied in one of two ways:1)  In Central Administration, go to Application Management->SharePoint Site Management->Site collection quotas and locks.  Once you have arrived, select the correct application and site collection, and you will have the opportunity to view and set the lock status of the collection (it most likely will be set to "Read-only", and you'll want to move that radio button to "Not locked").2)  Fire up stsadm and issue the following command:stsadm -o setsitelock -url http://myportalsitecollection -lock none

  • Dynamic dns client stops updating when login off Windows

    - by Sami-L
    Running a dynamic dns updater software on Windows server 2008 R2, when I log off the software stops updating, I concluded that I have to look for a dynamic dns client running as service, I found this task a bit heavy since there is a big variety on the net, it needs a long time to make the right choice as many details are to pay attention to, free, masked fees, fees, installed on machine, configured on router, trusted, not trusted, compliant with OS, not, ... That's why I am here to ask for help on this matter, I would like to be advised by skilled people, to find a trusted free dns updater (client) for Windows which can run as service, and maybe which can send email when update fails.

  • Moving a Drupal between linux servers, best practice to avoid file-ownership problems

    - by zero
    I want to port over a Drupal commons 6x24 from a local LAMP-stack to a production webserver. Both systems run OpenSuse Linux. How do I do this, what are the most important steps. How should I handle file-ownership. It's important for me to have to have full control of the file ownership. If I use the wwwrun account, I frequently run into problems, due to a very strict webserver-admin. See for example the long history of looking for fixes and solutions see this thread and even more interesting see this very long and impressive thread here. All troubles I run into have to do with file-owernship and permissions. This is my current setup; Note: This was just a quick hacked installation - quick and dirty.

  • How to control the time before Windows 7 wakes from standby and hibernates?

    - by Ricket
    Ever since I reformatted my laptop, it just hasn't been the same. Before reformatting I noticed that if it was in standby for around 24 hours, it would automatically wake up and go into hibernation. I think that's a pretty cool feature and I didn't mind it. But lately, it's been waiting only a few hours (maybe 3-6; I haven't really timed it or paid enough attention) before waking up from standby and going into hibernation. There have been a few instances where this has been bothersome, and I'd like to change it back to a nice long wait time. Where is this setting? What setting in Windows controls the time before the computer wakes up from standby and goes into hibernation?

  • Starting with text based MUD/MUCK game

    - by Scott Ivie
    I’ve had this idea for a video game in my head for a long time but I’ve never had the knowledge or time to get it done. I still don’t really, but I am willing to dedicate a chunk of my time to this before it’s too late. Recently I started studying Lua script for a program called “MUSH Client” which works for MU* telnet style text games. I want to use the GUI capabilities of Mush Client with a MU* server to create a basic game but here is my dilemma. I figured this could be a suitable starting place for me. BUT… Because I’m not very programmer savvy yet, I don’t know how to download/install/use the MU* server software. I was originally considering Protomuck because a few of the MU*s I were more impressed with began there. http://www.protomuck.org/ I downloaded it, but I guess I'm too used to GUI style programs so I'm having great difficulty figuring out what to do next. Does anyone have any suggestions? Does anyone even know what I'm talking about? heh..

  • Windows 7 Bootcamp to see data doubler SATA SSD in Optical Bay Connector

    - by bumble_bee_tuna
    Hi I purchased a OWC data doubler http://eshop.macsales.com/item/OWC/DDAMBS0GB/ ... Long story short it lets you add a second HD to your macbook pro in place of the cd/dvd drive (which is useless anyway, impossible to get stuff out when stuck). My current setup is 600gb intel SSD bootdrive 100gb partition for OSX / 500gb for Windows 7 Prof from Bootcamp (use 99 % of time). My desire is to have a second 300gb SSD to run disk intensive VM's off of. So I added a second 300gb intel SSD (again, NO desire to boot off of) on the sata optical port. I can see the drive no problem if I boot in to OSX, however, can't see it in disk management on Win7 ??? Any ideas similar experience ... Funny thing is I can see it in "Device Manager Disk Drivers" but not Disk Management ??? Also no I don't want to use Fusion/Parallels this is a waste of resources for me.

  • Control convention for circular movement?

    - by Christian
    I'm currently doing a kind of training project in Unity (still a beginner). It's supposed to be somewhat like Breakout, but instead of just going left and right I want the paddle to circle around the center point. This is all fine and dandy, but the problem I have is: how do you control this with a keyboard or gamepad? For touch and mouse control I could work around the problem by letting the paddle follow the cursor/finger, but with the other control methods I'm a bit stumped. With a keyboard for example, I could either make it so that the Left arrow always moves the paddle clockwise (it starts at the bottom of the circle), or I could link it to the actual direction - meaning that if the paddle is at the bottom, it goes left and up along the circle or, if it's in the upper hemisphere, it moves left and down, both times toward the outer left point of the circle. Both feel kind of weird. With the first one, it can be counter intuitive to press Left to move the paddle right when it's in the upper area, while in the second method you'd need to constantly switch buttons to keep moving. So, long story short: is there any kind of existing standard, convention or accepted example for this type of movement and the corresponding controls? I didn't really know what to google for (control conventions for circular movement was one of the searches I tried, but it didn't give me much), and I also didn't really find anything about this on here. If there is a Question that I simply didn't see, please excuse the duplicate.

  • Browser language detection & content ranking for new language on the same site.

    - by Arnaud
    I've been reading a lot about it but it's still really hard to make up my mind. My understand is that if your website provide a link to the other language, this should not be an issue for google as long as your links are clear and clean, google will be able to make his way through it. The website was orginaly in french and I added the english version and I'm just worry that english speaker will just leave if the site is not in the correct language, for the home page I just wanted to get the value from the browser and redirect it to /fr/ or /en/ for the first page. (using php this will be very easy) Could you guys have a look at it and tell me what you think about it http://tinyurl.com/bpc5bn9 I don't want to get it wrong and lost my ranking with google. Also the website has good rank on the french side and the english has been online for 2 weeks and only get few visit a day, is that because all the back link refer to /fr/ and google is cleaver enough to decide that they are 2 differantes website and the back link will have to point to /en/ to increase the ranking value? Or will take few more weeks for the website to grow? Thanks for your hep

  • Easily tell if focused on VirtualBox window?

    - by Benjamin Oakes
    Is there a way to make it very obvious that my VirtualBox window isn't in focus? The problem I'm having is switching between workspaces on Ubuntu or OS X and then trying to type in my Windows virtual machine, only to find that it's not in focus. The Windows window looks like it's in focus (based on the title bar), but I'm actually typing in Firefox on the host machine, for example. It's even worse because the Windows text insertion cursor is blinking to show focus. Ideally, I'd like the VM's display to get unsaturated (e.g. a "partial" grayscale) when not in focus, just to prevent this keyboard-focus problem. Other options would be fine too, as long as I don't have to second guess where my focus is. I'm not using the seamless mode -- the display is all within a window.

  • How to view status of software RAID 1 resynching?

    - by tputkonen
    I have two 500 GB disks and yesterday I mirrored first drive to the second one using software RAID 1. PC has now been on for 30 hours. Both disks say "Resynching", but there is no progress indicator. In addition, there is a small yellow exclamation mark on both disks. My questions are: How long could the synch take for 500 GB drive with about 150 GB of data? PC has 4 GBs of RAM and AMD dual core 4000+ Is there a way to monitor status of the synching? How can I check what the exclamation mark means?

  • How to recover broken dpkg after lucid-bleed ppa-purge?

    - by TryTryAgain
    Did a ppa-purge of lucid-bleed and dpkg didn't downgrade properly and now it is broken. dpkg: PreDepends: tar (>= 1.23) but 1.22-2ubuntu1 is to be installed What scares me is when simulating the removal of dpkg I get: Removing this package may render the system unusable. Are you sure you want to do that? and then the list of packages which depend on it, which will also be removed, is obviously very long. Is it safe for me to remove dpkg just to reinstall it? How would I ensure the list of packages which were also removed are then reinstalled? Will forcing the version of dpkg help? (FYI: simulating a forced version brings up a much smaller list of applications which will also be removed). Any other suggestions? Additional information based on comments: ppa-purge log: http://pastebin.com/1kT8cLvP If I sudo apt-get install dpkg=1.15.5.6ubuntu4.5 I get The following packages have unmet dependencies: libdpkg-perl: Depends: dpkg (= 1.15.8) but 1.15.5.6ubuntu4.5 is to be installed which sucks because that means more would be broken after doing so...but when I force the version through Synaptic I get: To be removed alien, build-essential, cdbs, checkinstall, debhelper, devscripts, dpkg-dev, google-earth-stable, googleearth-package, libdpkg-perl, lintian, lsb, lsb-core, lsb-cxx, lsb-desktop, lsb-graphics, lsb-languages, lsb-multimedia, lsb-printing, lsb-qt4, lsb-security, ubuntu-dev-tools.

  • FreeDOS reinstallation -- accidental script change

    - by jerry2144
    I'm extremely new to FreeDOS and I got a new HP desktop computer with the FreeDOS operating system. I messed up and accidentally changed its scripts and messed around with it's boot order. Long story short, I'm getting a disk error when I boot up. I believe I need to just reinstall FreeDOS and all should be good, but I want to get someone's opinion with much more experience than my own. Also, if someone could guide me through the installation process using a DVD installer that would be amazing. I have already downloaded the FreeDOS iso image and unzipped it. I don't know what I need to do now though. Should I even have unzipped it?

  • MvcReportViewer v.0.4.0 is available!

    - by Ilya Verbitskiy
    Originally posted on: http://geekswithblogs.net/ilich/archive/2014/06/04/mvcreportviewer-v.0.4.0-is-available.aspxToday I released new version of MvcReportViewer. This release contains mostly bug fixes reported by library users. I am glad to see that Open Source model works and people try to contribute to the project! Thank you everybody for your bug repots and help with the project. Version 0.4.0 Added support for ASP.NET MVC 5 Removed jQuery dependency. I have not tested it on IE8 or earlier versions. Any help with testing is welcome! Fixed problem with SSRS keep-alive cookies. Keep-alive cookies are issued every time a report is opened during a browser session. Many people don't restart their browsers and in my case, Chrome doesn't get rid of the cookie session data on close - had to manually delete them for the reports to start working again. I added KeepSessionAlive control settings to manage SSRS keep-alive behavior. It is set to false by default to fix Bad Request 400: Request Too Long issue. You can find usage example in Fluent.cshtml. Fixed the bug when ReportViewer Control parameters was not parsed when ShowParameterPrompts parameter had not been set. Changed public static MvcReportViewerIframe MvcReportViewer method to use IEnumerable<KeyValuePair<string, object>> reportParameters instead of simple object. The reason is users reported that they mostly use multiple report parameters’ values. Added support for SSRS hosted on Windows Azure. Users should set MvcReportViewer.IsAzureSSRS property to true in Web.config to use Windows Azure authentication. I do not have Windows Azure SSRS and build the code using http://msdn.microsoft.com/en-us/library/gg552871.aspx#Authentication article. It would be nice if somebody from community tested the change or provided me a test report on Windows Azure for testing purposes.

  • How to share malicious source code?

    - by darma
    I have a client whose site (not one i developed) is infected by a trojan/malicious code. I have asked him to send me the dirty files in a zip but either gmail or unzipping is blocking them. I've tried text files and word files, and i'm suspecting many different file types will be blocked the same way, either by my mail client, anti-malware software, browser etc. (which is normal). Do you know a way he could share those lines so i can read them and do some research about the malicious source code? An image/screenshot of his text editor would be an idea but the files are long + i'd prefer to be able to copy/paste from them. Thank you!

  • "RPC Server is unavailable" on Windows 7 Client with Samba3 making logon impossible

    - by HalloDu
    I am running an Samba 3.4.* Server with LDAP Backend on Ubuntu 10.04 LTS as a PDC for purely Windows 7 Clients (about 50). It worked quite fine for a long time, but now sometimes on some machines (really strange to replicate) I cannot login, because he tells me that there are no logon servers. When I look in the machines eventlog after logging in locally, the only error it shows is: "RPC Server is unavailable". The system was ported quite a while back from another machine running the same software versions to this new one. Are there maybe trust or caching issues between the workstations and the domain controller? The number of machines affecting is steadily increasing and so do you know any reason as to why this problem occurs? Any information on workstation and domain trust would also be welcome (After googleing I did not find anything really enlightening).

  • Non-Obvious Topics to Learn for Game Development

    - by ashes999
    I've been writing games for around 10 years now (from QBasic to C# and everything in-between). I need to start stretching my skills into different areas. What are other, surprising topics I should read up on? Expected topics would include the usual suspects: Programming language of your choice Scripting language Source control Project management (or Agile) Graphics API Maybe some AI (A* path-finding?) Physics (projectile physics) Unit testing (automated testing) I'm looking for more esoteric topics; things that you don't expect to need to know, but if you do know them, they make a difference. This could include things like: Art skills (drawing, lighting, colouring, layout, etc.) Natural language processing The physics of sound (sound-waves, doppler effect, etc.) Personally, I feel that having technical art skills (eg. can make decent art-work if you can only come up with ideas; or, following Photoshop/GIMP tutorials) was the most beneficial for me. This is not intended to be an open-ended question; I'm looking for specific skills that helped you and you expect will continue to benefit you in the short- and long-term.

  • How do I stop CRM from asking for admin credentials when printing report

    - by Ac0ua
    Problem: When printing a report in CRM, I am asked by the UAC for admin credentials. There is a long URL: https://(crm_hostname)/reserved.ReportViewerWebcontrol.axd?ReportSession=(ID)ControlID=(ID)Culture=1333&UICulture=1033&ReportStack=1&OpType=PrintCab Info: There are three users that have the issue laied out here. They are not admins of any kind. It looks like it is asking for permission to allow SQL Server Reporting Services 2008 to run. When I put my credentials in, it just brings up the Print dialog box (this is fine, just stop asking for credentials). I know this might sound silly but I downloaded and installed "SQL Server Reporting Services 2008" hopping my credentials would give permission right from the beginning. Giving the users local admin, I was told is not an option. Note: I did post this on community (dot) dynamics (dot) com but, they are not a very active website. Thanks for any help even if it just points me in the right direction!

  • Benefits of Server-side Coding

    There are numerous advantages to server scripting languages over client side languages in regards to creating web sites that are more compelling compared to a standard static site. Server side scripting are scripts that are executed on a web server during the compilation of data to return to a client. These scripts allow developers to modify the content that is being sent to the user prior to the return of the data to the user as well as store information about the user. In addition, server side scripts allow for a controllable environment in which they can be executed. This cannot be said for client side languages because the developer cannot control the users’ environment compared to a web server. Some users may turn off client scripts, some may be only allow limited access on the system and others may be able to gain full control of the environment.  I have been developing web applications for over 9 years, and I have used server side languages for most of the applications I have built.  Here is a list of common things I have developed with server side scripts. List of Common Generic Functionality Send Email FTP Files Security/ Access Control Encryption URL rewriting Data Access Data Creation I/O Access The one important feature server side languages will help me with on my website is Data Access because my component will be backed with a SQL server database. I believe that form validation is one instance where I might see server-side scripts and JavaScript used interchangeably because it does not matter how or where the data is validated as long as the data that gets inserted is valid. However, I would have to say that my personal experience would have to sway me in deciding what type of languages to use for form validation because they both have advantages and disadvantages based on the each situation.

I have carefully examined the latest trends in the Computersphere with whatever tools I had at my disposal (nothing really fancy was used) and came to a conclusion that for a database pro the *hottest* topic today is undoubtedly the #BigData and all the rapidly growing and spawning ecosystem around it.

  • Screen flicker -> Severe System Slowdown?

    - by Adam Robinson
    I'm using a Dell D830 laptop, and over the last few weeks it's been developing a very irritating screen flicker problem that leads to the system slowing down almost to the point of unusability. At seemingly random times (no commonality between how long the system has been running, what I was doing, what applications were open, etc.) my screen (I use two external LCD's with the laptop closed in a dock) flickers for a moment, then the system becomes incredibly slow. The screen redraws painfully slowly--almost like what you might expect to see with generic graphics drivers installed--and the entire system is maddeningly unresponsive. The only thing that seems to be able to correct the issue is a restart. I've checked the event logs and nothing out of the ordinary is there, and definitely nothing that's common to all of the events. I'm running XP Pro SP2. Any ideas?

    In my HTML5 canvas game, I need to cross-fade two sprites which have some glow around them. (Glow is backed into sprites.) Initially, the first sprite is visible. During the cross-fade the first sprite should vanish, and be replaced with the second one. How exactly the cross-fade is done — does not matter, as long as it is smooth and there are no visual glitches. I've tried two techniques: During the cross-fade I simultaneously interpolate alpha of the first sprite from 1.0 to 0.0, and alpha of the second sprite — from 0.0 to 1.0. With this technique I can see background in the middle of the cross-fade. That's because both sprites are semi-transparent most of the time. During the cross-fade I first interpolate alpha of the second sprite from 0.0 to 1.0 (first sprite alpha is at 1.0), and then interpolate alpha of the first sprite from 1.0 to 0.0. With this technique background is not seen, but the glow around sprites flashes during the cross-fide — when both sprites are near the full visibility. In non-HTML5 game I'd use shaders to do cross-fade separately in RGB and alpha channels. Is there a trick to do the cross-fade I need in HTML5 without visual glitches?
