• Working with Active Directory and Windows Small Business Server 2008

  - by AreYouSerious

  I have to say that in most of my time as a network engineer I have had the opportunity to play with servers, but mostly it's been to put our management software on, and that was about it. I have been a Systems Network Engineer for about three months now, and as such I have been respnosible for the configuration of our test devices... this being said, I have had to start working through how to configure and apply such things as GPO through a new forest, domain and OU. This being said I have configured about three different GPO's and applied them to different locations. The first laptop that I brought into the domain took the default Domain group Policy... this was cool, I got excited... then When I tried to bring in the second Laptop, it didn't take the policy. I looked at the configuration, and the default domain policy was applied to domain computers, however since the laptop resides in the SBS Computers of the OU that was created, SBS created individual policies for XP and Vista for that OU, which I was unaware of. So the default policy for that ou overrode the domain policy and none of the options that were defined in the Domain policy were applied... this being said, I am now working on putting the default Domain as an applicable policy in the OU, thus I won't have to reconfigure another policy to mirror the Domain Policy... here goes nothing!!!.... More to follow Later.

• Firefox- How to change font size of items in bookmarks sidebar

  - by TheClamkinator

  In Windows. (I know I can open Desktop > Properties > Appearance > Advanced [and figure out which item determines it; probably Menu]. But, I don't want other things changed - just the bookmarks. This is because I have so many and I want more of them to display. I did see the question on changing font size of items in folder, on bookmarks toolbar, and sub-folders, etc; But, I'm talking sidebar on firefox, I don't have Google Chrome and I am not a developer.

• automated printouts from a wireless printer

  - by Piotr

  I have a wireless printer which is always on, and an always on fanless linux server. Looking at the mprinter project on Kickstarter I started to wonder if there is an app somewhere in the internet already that will allow to prepare an automated daily printout based on some settings. things to be printed could include - weather forecast for my locations, todo`s scheduled for that day, a "quote of a day" or "word of the day", stats from google analytics for my site, and many more ... I would set a printout at 6:15 every work day so its on my printer when I am already up, having a coffee. anyone knows something that can be used for such purpose? While I know this can be done by combining the power of TeX, cron and a script language to manage the dynamic part of the PDF I believe this is a use case someone has already addressed.

• O'reilly certification in PHP worth it?

  - by editzombie

  I asked this question over on stack overflow but I didn't realise it wasn't really the place for not so technical questions. I've seen quite a few related threads on this forum so I thought I'd try and get some feedback here: This is my first time asking a question on this forum, though I´ve read it a lot. I apologise if this is repeating a thread. I´m interested in getting into web development. I am a video editor by trade but living in Spain the way things are at the moment its very difficult to find work. I have some very basic knowledge of HTML and CSS and a little bit of flash and have designed a few little personal websites myself. I also worked for a online marketing production company where I worked a little on blog design in Blogger amongst other social media. So thats my background, but I´m trying to expand my skills and get into web development as a career or in general part of my skill base, I was thinking particularly about PHP/MySQL. I have worked a little on some of the Lynda.com tutorials and have invested in a book (Sams Teach Yourself PHP, MySQL and Apache). I´m still finding it very difficult to progress. I know I should really try some practice projects (any reccomendations would be welcome). But I was also thinking about doing one of the O´Reilly certification courses and was wondering whether it would be worthwhile for a noob like me. I hear that the courses are associated with an American University which I guess gives it more clout. Any other thoughts you guys have about how to make progress in learning web development would be fantasic. Thanks in advance.

• Acer S3 SSD and HD Deleted partitions?

  - by user207784

  I'm new to Linux and Ubuntu, and I think I have a problem. I have an Acer Aspire S3 with 20GB SSD and 320GB HD. I installed Ubuntu 12.04 64bit on it today, and when it asked about partitions, without knowing better, I erased the partitions. There is some information at https://help.ubuntu.com/community/AspireS3 about using the SSD and HD efficiently, but since I deleted the partitions, I don't know what to do. How can I recreate the partitions mentioned in the above link so that I can take advantage of having SSD and HD? I installed GParted, but I don't know what I should do now, and I don't want to screw things up further. I greatly appreciate any help that can be offered me. EDIT: I was playing with GParted, and I just realized that I can see dev/sda and dev/sdb, so perhaps I didn't do something horrible to my partitions. I am also sorry for asking such (dumb?) questions. At this point, is there a way to tell whether I have actually screwed up my partitions? Thanks, Joe

• how to architect this to make it unit testable

  - by SOfanatic

  I'm currently working on a project where I'm receiving an object via web service (WSDL). The overall process is the following: Receive object - add/delete/update parts (or all) of it - and return the object with the changes made. The thing is that sometimes these changes are complicated and there is some logic involved, other databases, other web services, etc. so to facilitate this I'm creating a custom object that mimics the original one but has some enhanced functionality to make some things easier. So I'm trying to have this process: Receive original object - convert/copy it to custom object - add/delete/update - convert/copy it back to original object - return original object. Example: public class Row { public List<Field> Fields { get; set; } public string RowId { get; set; } public Row() { this.Fields = new List<Field>(); } } public class Field { public string Number { get; set; } public string Value { get; set; } } So for example, one of the "actions" to perform on this would be to find all Fields in a Row that match a Value equal to something, and update them with some other value. I have a CustomRow class that represents the Row class, how can I make this class unit testable? Do I have to create an interface ICustomRow to mock it in the unit test? If one of the actions is to sum all of the Values in the Fields that have a Number equal to 10, like this function, how can design the custom class to facilitate unit tests. Sample function: public int Sum(FieldNumber number) { return row.Fields.Where(x => x.FieldNumber.Equals(number)).Sum(x => x.FieldValue); } Am I approaching this the wrong way?

• Faster 2D Collision detection

  - by eShredder

  Recently I've been working on a fast-paced 2d shooter and I came across a mighty problem. Collision detection. Sure, it is working, but it is very slow. My goal is: Have lots of enemies on screen and have them to not touch each other. All of the enemies are chasing the player entity. Most of them have the same speed so sooner or later they all end up taking the same space while chasing the player. This really drops the fun factor since, for the player, it looks like you are being chased by one enemy only. To prevent them to take the same space I added a collision detection (a very basic 2D detection, the only method I know of) which is. Enemy class update method Loop through all enemies (continue; if the loop points at this object) If enemy object intersects with this object Push enemy object away from this enemy object This works fine. As long as I only have <200 enemy entities that is. When I get closer to 300-350 enemy entities my frame rate begins to drop heavily. First I thought it was bad rendering so I removed their draw call. This did not help at all so of course I realised it was the update method. The only heavy part in their update method is this each-enemy-loops-through-every-enemy part. When I get closer to 300 enemies the game does a 90000 (300x300) step itteration. My my~ I'm sure there must be another way to aproach this collision detection. Though I have no idea how. The pages I find is about how to actually do the collision between two objects or how to check collision between an object and a tile. I already know those two things. tl;dr? How do I aproach collision detection between LOTS of entities? Quick edit: If it is to any help, I'm using C# XNA.

• Keyboard layout to shift wasd keys

  - by Joel Coehoorn

  I like to play video games on my computer. One of the things that bugs me, though, is how the wasd keys became the standard movement keys in first person shooters and mmorpgs. To me, esdf makes a lot more sense, because that matches your normal hand placement for typing. "Fixing" that layout is always the first thing I do when installing a new game. Sadly, this is often a pain in the neck, and some games won't let you do it at all. Is there an alternative keyboard layout you can install that will just switch these around, so the wasd keys fall in the esdf positions? And is low-level enough two work with DirectX/DirectInput, perhaps that works with the language bar for easy swapping back and forth?

• A way to auto cycle (close) through all screen sessions

  - by JBWhitmore

  I frequently use screen when I log into the interactive nodes to a supercomputer that I have access to -- and I often run things and move on. There are about 20 separate nodes that I can log into; and if I check any one of them I'll have something like 4 detached sessions. Each of those sessions will have maybe 5 screen sessions within that. Is there a quick way to cycle through all of these and close them down if they are not running any processes? My current process is to screen -ls and then screen -r #### then type exit until I'm back to the base screen.

• Permission issue when deleting folders

  - by nate

  I can't delete some folders and some actions are being denied because I do not have administrator access. But in my user account it says i am an administrator. I also just upgraded from Windows Vista 64-bit to Windows 7 64-bit, but I had this problem before upgrading, but now I am being denied more things. I also can't reorder the way files are sorted in folders. I can sort them through the default means, but I literally can't drag and drop them if I want to reorder them. I don't know if this is another problem or if it is related. Let me know if you need more information. Thanks!

• embedded tomcat 7 behind iis 7.5 proxy ssl problems

  - by user1058410

  I'm using embedded tomcat 7 behind a iis 7.5 proxy server, with requests being forwarded to tomcat with arr. Everything works fine unless iis is set to require ssl. Then things like links that are generated dynamically in .jsp files on tomcat don't work right. For example if a link is supposed to point to _https://somewhere.com:443 it will be wrote as _http://somewhere.com:8080 (8080 is the port tomcat is running on). The problem seems to come from when tomcat looks at itself to build out the url it sees correctly that it is running on _http://somewhere.com:8080, but i need it to think otherwise. Does anybody know how to accomplish this without using ssl between iis and tomcat? Sorry for the underscores in front of the imaginary urls.

• Yelp, Google's API for restaurants help

  - by chris

  Ok I have looked into this, and I'm not sure if anyone else has experience with it. I'm having termendous difficulties with Yelp and Google's API. To help explain what I am trying to do here is the concept of the website. We would have to pull restaurants based on user distance, and then randomize them based on quality of restaurant based on feedback from review websites (Yelp, Google, urbanspoon, zagat, opentable, kudzu, yahoo - doesn't have to be from all), and feedback from our users (on results page for the random restaurant users can select good recommendation/bad recommendation). There’s a lot we could calculate for our formula. Things that will dictate your results will be based on if you’re at home or work. If you’re at home you will have more time to drive out to the city to grab some dinner or lunch. If you’re at work we would have to recommend restaurants nearby as lunch is typically 30 minutes to a hour. A 30 minute lunch would require take out most likely or quick service. A hour lunch break you could dine in at a local fine dining restaurant. So in a nutshell, user comes to website. Select if they're at home or work, click submit and we will have a random restaurant selected for them to go. If they don't like it they can click retry and a new restaurant can show. The issue I am having is using the API to gather all the restaurants in the US. I know it can be done because there are similiar websites/apps that pull restaurants that are closest to you such as Ness, Alfred, and I believe there's two more but I can't remember the names. Anyone know if this can be accomplish?

• Self-imposed lockout from program

  - by Alex

  I'm plagued with a lack of willpower. I recently started looking for solutions, and came across a program for macs called SelfControl which completely blocks one's access to a given set of websites for a given period of time (you can delete the program/restart your computer/do almost anything and it will still block those sites for the specified time period, and doesn't require a password to do it.) Unfortunately, there are no windows analogues. The one that comes the closest is Cold Turkey. It has the functionality whereby you set a time in the future, specify a list of websites (or programs - eg explorer, firefox, chrome) and you are blocked from accessing them for the whole duration. No password can undo it, no system reboot, etc. The problem is that the program is a buggy piece of garbage, and in order to ensure that you're not locked out from websites forever, you have to run an uninstaller which is just an exe file accessible at any time which completely defeats the purpose of a self-imposed program lockout. I want to make a better version of that program, or find a simple way to prevent access to a given set of programs over a given period of time with no way around it. I've only taken a few introductory courses in java (math major), but the internet is really having a negative effect on my studies, and the only way I can do work is to eliminate all distractions. What do I need to learn in order to make a program with the following properties: Given a set of .exe files, and a time in the future , this program will prevent access to the given .exe files until current time = given time restarting the computer doesn't interfere with the program, one can't uninstall the program until current time = given time, one can't create another instance of the program to block itself I don't care how much programming knowledge i need to acquire in order to make this program, so please give me a specific list of things that I need to study in order to make this happen, or if something like this exists, then please let me know.

• EE vs Computer Science: Effect on Developers' Approaches, Styles?

  - by DarenW

  Are there any systematic differences between software developers (sw engineers, architect, whatever job title) with an electronics or other engineering background, compared to those who entered the profession through computer science? By electronics background, I mean an EE degree, or a self-taught electronics tinkerer, other types of engineers and experimental physicists. I'm wondering if coming into the software-making professions from a strong knowledge of flip flops, tristate buffers, clock edge rise times and so forth, usually leads to a distinct approach to problems, mindsets, or superior skills at certain specialties and lack of skills at others, when compared to the computer science types who are full of concepts like abstract data types, object orientation, database normalization, who speak of "closures" in programming languages - things that make little sense to the soldering iron crowd until they learn enough programming. The real world, I'm sure, offers a wild range of individual exceptions, but for the most part, can you say there are overall differences? Would these have hiring implications e.g. (to make up something) "never hire an electron wrangler to do database design"? Could knowing about any differences help job seekers find something appropriate more effectively? Or provide enlightenment or some practical advice for those who find themselves misfits in a particular job role? (Btw, I've never taken any computer science classes; my impression of exactly what they cover is fuzzy. I'm an electronics/physics/art type, myself.)

• When can I publish a software tool written at work?

  - by AlexMA

  I'm working on a software problem at work that is fairly generic, but I can't find a library I like to solve it, so I'm considering writing one myself (at least a bare-bones version). I'll be writing some if not all of the 1.0 version at work, since I need it for the project. If turns out well I might want to bring the work home and polish it up just for fun, and maybe release it as an open-source project. However, I'm concerned that if I wrote the 1.0 version at work I may not be allowed to do this from a legal sense. Obviously I could ask my boss (who probably won't care), but I'm curious how other programmers have dealt with this issue and where the law stands here. My one sentence question is, When is it okay (legally/ethically) to open-source a software tool originally written by you for work at work? What if you have expanded the original source significantly during off-hours? Follow-up: Suppose I write the whole thing at home on my time then simply use it at work, does that change things drastically? Follow-up 2: Note that I'm not trying to rip off my employer (I understand that they're paying me to build products that they own)--I'm just wondering if there's a fair way of doing this for all involved... It would be nice if some nonprofit down the road could use my code and save them some time. Also, there's another issue at stake. If I write the library for a very simple, generic thing (like HTML tables in Javascript), does that mean I can never again do so on my own time without putting myself at legal risk (even if it was a whole new fresh rewrite or a segment of a larger project). Am I surrendering my right to write code for this sort of project for the rest of my life (without this company's permission), since the code at work might still be somewhere in my brain influencing me? This seems related to software patents, as a side-note.

• Server goes offline. What to look for?

  - by Jonathan Sampson

  I'm using a new virtual server through GoDaddy, and this morning I received a call from the powers that be informing me our website was offline. After confirming this, I requested a power cycle through our GoDaddy control panel, and within a minute or two the server was back online. I made the call, and reported the news that we're back up. Of course, a couple minutes later we're down again. I tried connecting through PuTTy, and it takes forever to prompt me for a username, and each successive prompt takes a long time to come up. I'm using CentOS. So my questions are: How can I determine the cause? What types of things can I do to prevent this in the future? One interesting, and perhaps relevant, observation is that yesterday our bandwidth consumption was about 20% greater than our top figures from the past month.

• Setting up a software company...

  - by ThePower

  Hi all, I am a Software Engineer who wants to start developing and selling a range of products. I have some in depth ideas that I would like to go on to develop individually and sell under my own company name. Does anyone with any experience in this process have any information with regards to the route to take and process of setting things up so that I may be able to sell my applications? Also any information regarding copyrighting the material would be excellent. I am looking for the easiest way to set up a business that will allow me to have a name in which I can start selling applications to a variety of sources under. I didn't quite know which site to post this on so I hope it is relevant for superuser. Regards, Lloyd

• How do I setup a Gnome 3.2 VPN connection (Fedora 16)

  - by mpeters

  I just switched to Gnome 3 on a new laptop to try it out. Lots of things are different, but I think I can get used to them. But I'm having a real problem trying to figure out how to get the new network manager to setup a VPN through the GUI. I have openvpn, NetworkManager and NetworkManager-openvpn installed, but when I click on the network icon in gnome-shell there is nothing about vpn connections in there. When I click the "Network Settings" link in that menu I just see menus for Wired, Wireless and Network Proxy and none of those screens has anything for VPN connections either. Any suggestions about where I need to look to setup my connections and how to make it easier connect when I need to?

• How to make WinServer's AD work with Linux DNS/DHCP on VMware?

  - by Borald

  Hope you're fine. I got 2 virtual machines : Windows Server 2008 with Active Directory installed. Linux that works as a DNS and DHCP Server I need to make them work together, but I don't if this is going to be possible because VMWARE is sharing the NIC with other virtual machines and computer itself. I've assigned different IP static adresses to the servers. Is there a way for me to make these things get interconnected and test them on some virtual clients ? Any help will be much appreciated... (useful links,tutorials,..) Thanks in advance !

• Sorting for 2D Drawing

  - by Nexian

  okie, looked through quite a few similar questions but still feel the need to ask mine specifically (I know, crazy). Anyhoo: I am drawing a game in 2D (isometric) My objects have their own arrays. (i.e. Tiles[], Objects[], Particles[], etc) I want to have a draw[] array to hold anything that will be drawn. Because it is 2D, I assume I must prioritise depth over any other sorting or things will look weird. My game is turn based so Tiles and Objects won't be changing position every frame. However, Particles probably will. So I am thinking I can populate the draw[] array (probably a vector?) with what is on-screen and have it add/remove object, tile & particle references when I pan the screen or when a tile or object is specifically moved. No idea how often I'm going to have to update for particles right now. I want to do this because my game may have many thousands of objects and I want to iterate through as few as possible when drawing. I plan to give each element a depth value to sort by. So, my questions: Does the above method sound like a good way to deal with the actual drawing? What is the most efficient way to sort a vector? Most of the time it wont require efficiency. But for panning the screen it will. And I imagine if I have many particles on screen moving across multiple tiles, it may happen quite often. For reference, my screen will be drawing about 2,800 objects at any one time. When panning, it will be adding/removing about ~200 elements every second, and each new element will need adding in the correct location based on depth.

• internet speed and routers are controlled by whom

  - by Ozgun Sunal

  i need to learn two things. each is related to other a bit. The first one is, while our LAN speed is usually 100 Mbps or at gigabit levels(very big compared to WAN speeds), WAN speed for instance DSL connections are far less than this. However, we are able to download huge files at those Mb speeds. Isn't this weird? [my real concern is why WAN speed is lower than LAN speeds] Who controls those routers around the large Internet? (while we, as web clients are connected to Internet, packets travel through those routers to the destination network/s).But, are those routers all inside the ISP network and if not, who controls those large numbers of routers?

• How should an undergraduate programmer organize his time learning the maximum possible?

  - by nischayn22

  I started programming lately(pre-final year of a CS degree) and now feel like there's a sea of uncovered treasure for me out there. So, I decided to cover as much as is possible before I look out for a job after graduation. So, I started to read books (The C++ Programming Language, Introduction to Algorithms, Cracking the Coding Interview, Programming Pearls,etc ) participate in StackExchange sites, solving problems (InterviewStreet and ProjectEuler), coding for open source, chatting to fellow programmers/mentors and try to learn more and more. Good,then what's the problem?? The problem is I am trying to do many things, but I am doubtful that I am still utilizing my time properly. I am reading many books and sometimes I just leave a book halfway (jumping from one book to another), sometimes I spend way too much time on chatting and also in getting lost somewhere in the huge internet world, and lastly the wasteful burden of attending classes (I don't think my teachers know good enough or I prefer learning on my own) May be some of you had similar situation. How did you organize your time? Or what do you think is the best way to organize it for an undergraduate? Also what mistakes am I making that you can warn me of

• Find & Replace in blogger

  - by Benjol

  (I just learnt that Yahoo are shutting down Geocities, this is a bummer as I used my account there to host two icons, in the days when Blogger didn't upload gifs. Now those two icons are referenced in every one of my 600+ posts). Blogger doesn't have a "Find & Replace in all posts" function. I'm wondering about using the API to hack something together, and wondered if anyone has already tried playing with the API, if there are any tips or things to avoid. Also if there isn't a sneaky shortcut (like switching to ftp, doing the replace locally then switching back?). Not 100% programming related, please be lenient, or at least answer my question before closing it!

• Building a List of All SharePoint Timer Jobs Programmatically in C#

  - by Damon Armstrong

  One of the most frustrating things about SharePoint is that the difficulty in figuring something out is inversely proportional to the simplicity of what you are trying to accomplish.  Case in point, yesterday I wanted to get a list of all the timer jobs in SharePoint.  Having never done this nor having any idea of exactly how to do this right off the top of my head, I inquired to Google.  I like to think my Google-fu is fair to good, so I normally find exactly what I’m looking for in the first hit.  But on the topic of listing all SharePoint timer jobs all it came up with a PowerShell script command (Get-SPTimerJob) and nothing more. Refined search after refined search continued to turn up nothing. So apparently I am the only person on the planet who needs to get a list of the timer jobs in C#.  In case you are the second person on the planet who needs to do this, the code to do so follows: SPSecurity.RunWithElevatedPrivileges(() => {    var timerJobs = new List();    foreach (var job in SPAdministrationWebApplication.Local.JobDefinitions)    {       timerJobs.Add(job);    }    foreach (SPService curService in SPFarm.Local.Services)    {       foreach (var job in curService.JobDefinitions)       {          timerJobs.Add(job);       }     } }); For reference, you have the two for loops because the Central Admin web application doesn’t end up being in the SPFarm.Local.Services group, so you have to get it manually from the SPAdministrationWebApplication.Local reference.
