• Should I install an AV product on my domain controllers?

  - by mhud

  Should I run a server-specific antivirus, regular antivirus, or no antivirus at all on my servers, particularly my Domain Controllers? Here's some background about why I'm asking this question: I've never questioned that antivirus software should be running on all windows machines, period. Lately I've had some obscure Active Directory related issues that I have tracked down to antivirus software running on our domain controllers. The specific issue was that Symantec Endpoint Protection was running on all domain controllers. Occasionally, our Exchange server triggered a false-positive in Symantec's "Network Threat Protection" on each DC in sequence. After exhausting access to all DCs, Exchange began refusing requests, presumably because it could not communicate with any Global Catalog servers or perform any authentication. Outages would last about ten minutes at a time, and would occur once every few days. It took a long time to isolate the problem because it was not easily reproducible and generally investigation was done after the issue resolved itself.

• SSH - SFTP/SCP only + additional command running in background

  - by Chris

  there are many solutions described to get ur SSH-connection forced to only run SFTP by modifying the sshd_config by adding a new group match and give that new group a Forcecommand internal-sftp Well that works great but i would love to have a little more feature. My servers automatically ban IP's which try to connect often in a short time. So when you use any SFTP-Client, which opens multiple connections to work faster it can get banned instandly by the server for a long time. The servers have a script to whitelist users by administrator. I've modified this script to whitelist the user, which runs the script. All i need to do is now get the server to execute that script, when somebody logins. On SSH it's no problem, just put it in .bashrc or something like, but the Forcecommand don't runs these scripts on login. Is there any way to run such a shellscript before or at the same time as the Forcecommand get fired?

• Default profile for large

  - by user63434

  Hi I am setting up a master image to clone to all same machine type Windows 7 client, I login as administrastor and installed all the programs and changed the desktop settings etc, but my local administrator profile is 244megs in size, which will become the default profile of the local machine when sysprep, we have a 2003 server that I want to use mandatory profile for all login users which means I need to copy this profile to the server so when any users login to the domain they are using this profile, loading a 244megs profile is going to be very slow since it will be removed from the client when they logoff. So next time they login it will take a long time again. Is there anything I can do, can I just copy just the bare minimum files from the default profile to the server, as I am not sure what parts I need, I read that I must copy my documents, my documents/pictures so the folder redirection will work. What else do I need to copy to the server? I have firefox xmark sync also and MS words etc. THanks

• Nested/multiple brace-matching in Notepad++

  - by Melodic

  In Notepad++, is it possible to force all (or at least the 3 or 4 deepest) pairs of braces/brackets/parens/etc. that enclose the cursor to become highlighted? Preferably in different colors for each matched pair? For instance, in this example: int main(char** args) { if(blah) { ... } } If we place the cursor anywhere in the if-block, the main function's opening and closing braces should become one color, while the if-block's braces become another. The coloring for each block should stay the same as long the cursor is still in that block.

• Should sanity be a property of a programmer or a program?

  - by toplel32

  I design and implement languages, that can range from object notations to markup languages. In many cases I have considered restrictions in favor of sanity (common knowledge), like in the case of control characters in identifiers. There are two consequences to consider before doing this: It takes extra computation It narrows liberty I'm interested to learn how developers think of decisions like this. As you may know Microsoft C# is very open on the contrary. If you really want to prefix your integer as Long with 'l' instead of 'L' and so risk other developers of confusing '1' and 'l', no problem. If you want to name your variables in non-latin script so they will contrast with C#'s latin keywords, no problem. Or if you want to distribute a string over multiple lines and so break a series of indentation, no problem. It is cheap to ensure consistency with restrictions and this makes it tempting to implement. But in the case of disallowing non-latin characters (concerning the second example), it means a discredit to Unicode, because one would not take full advantage of its capacity.

• Any way to overwrite (not merge) Outlook contacts when importing from a file?

  - by Dan

  I'm trying to create a contact list for Outlook 2010 that will contain contact information for every person in my company. I intend on keeping the list current, which means I will be manually adding new employees to the contact list, and removing contacts who no longer work here. The contact list will reside in its own subfolder within the Outlook Contacts folder. I want to periodically export this contact list as a .csv file, and allow the other employees in the company to import it into Outlook on their own computer, thus providing them with a comprehensive and up-to-date company contact list. The problem is, Outlook 2010 only wants to merge contact lists, not overwrite them. This means that any contacts who are no longer with the company will not be removed from the contact lists on employee stations. Is there any way to force Outlook 2010 to overwrite the contact list? Oh how I long for the days of Outlook 2003 and its tidy .pab files.

• Web application access different between Domain Name and IP

  - by h82

  in our office, we have a web application running. When we access the application by the domain name, http://server.domain.com/application/name it will display the current version of application. However, when we go by the IP address, http://192.168.1.111/application/name it will display the old version of that application. One thing is that we can access that application either by http://server.domain.com/ (it will be redirected to the long URL automatically) or http://server.domain.com/application/name when we are using domain name. But only accessible via the exact URL when we use IP address. Why is it showing the old version and how can it be corrected? It is running JRun4, Apache on Red hat. I've checked in httpd.conf a bit but could not find any. Please advice what should be done to display the same (updated version) when we access using domain name or IP address. Thank you.

• What is excessive swapping.

  - by amateur barista

  This post led me to ask that question. Cache contention On a large site, if you are using MyISAM, contention occurs in the database tables when the cache is forced to clear after a node or a comment is added. With tens of thousands of filter text snippets needing to be deleted, the table will be locked for a long period, and any accesses to it will be queued pending the purge of the data in it. The same is true for the page cache as well. This often causes a "site hang" for a minute or two. During that time new requests keep piling up, and if you do not have the MaxClients parameter in Apache setup correctly, the system can go into thrashing because of excessive swapping.

• Do I really need to reboot for AD changes to be applied?

  - by stimms

  Every time I request a permission change the IT group at my company instructs me to wait 20 minutes and reboot the computer. I cannot believe that in this day and age you still need to reboot the computer to clear whatever cache stores the permissions locally. It feels like something out of the NT 4 days. Do you actually still need to reboot the computer? Is a logout/login sufficient? Is there still a long time(20 minutes) for the changes to propagate through the AD tree?

• Forwarding requests throught Apache to openVPN

  - by Ency

  I am wondering if it is possible to redirect requests through Apache to eg. OpenVPN. As long as I need to bypass firewall, I need to use port 80/443 for openVPN, but there is Apache server which has both port for itself. Client ---> Firewall (allows 80/443 only) --->| ---> Apache (80/443) ---> OpenVPN (1194) | -------------------------------------------- My Server I was thinking about mod_proxy, but I am not sure if it is good idea, have you got any ideas? I hope possible solution will be applicable on virtual host as well.

• What maintenance is required for a Postfix setup?

  - by JonLim

  I've taken a look at the setup and configuration process for a Postfix server, planning to use it for just sending emails out from my server. So far, I have these steps: Setup Postfix Configure Postfix Install DKIM Set SPF records Tune for performance Debug Seems rather straightforward. However, I was just wondering: are there any actions I should be taking for periodic maintenance of my Postfix setup? Thanks! EDIT: Also, just curious, how long would this entire setup ideally take? 30 - 60 minutes? More?

• Our company has 100,000s+ photos, how to store and browse/find these efficiently?

  - by tobefound

  We currently store our photos in a structure like this: folder\1\10000 - 19999.JPG|ORF|TIF (10 000 files) folder\2\20000 - 29999.JPG|ORF|TIF (10 000 files) etc... They are stored on 4 different 2TB D-link NASes attached and shared on our office network (\\nas1, \\nas2, and so on...) Problems: 1) When a client (Windows only, Vista and 7) wishes to browse the let's say \\nas1\folder\1\ folder, performance is quite poor. A problem. List takes a long time to generate in explorer window. Even with icons turned off. 2) Initial access to the NAS itself is sometimes slow. Problem. SAN disks too expensive for us. Even with iSCSI interface/switch technology. I've read a lot of tech pages saying that storing 100 000+ files in one single folder shouldn't be a problem. But we don't dare go there now that we experience problems on a 10K level. All input greatly appreciated, /T

• I can write code...but can't design well. Any suggestions?

  - by user396089

  I feel that I am good at writing code in bits and pieces, but my designs really suck. The question is how do I improve my designs (in order to become a better designer). I think schools and colleges do a good job of teaching people as to how to become good at mathematical problem solving, but lets admit the fact that most programs taught at school are generally around 1000 - 2000 lines long, which means that it is mostly an academic exercise and no way reflects the complexity of real world software (a few hundred thousand to millions of lines of code). This is where I believe that even projects like topcoder/project euler also won't be of much help, they might sharpen your mathematical problem solving ability - but you might become a theoretician programmer; someone who is more interested in the nice, clean stuff, and someone who is utterly un-interested in the day to day mundane and hairy stuff that most application programmers deal with. So my question is how do I improve my design skills? That is the ability to design small/medium scale applications that will go into a few thousand of lines of code? How can I learn design skills that would help me build a better html editor kit, or some graphics program like gimp?

• SEO Blog Indexing : Dot Wordpress Versus a Registered Domain?

  - by rumspringa00

  I've used Wordpress for a few of my client's sites, mostly small businesses and ecommerce sites. I have found through Google Analytics as well as the All in One Webmaster plugin that when it comes to social media, using Wordpress is a surefire way of getting your site indexed by Google and occasionally Bing and Yahoo. Since I am a heavy WP user, I'd like to contribute by registering a dot Wordpress domain for my portfolio. When using a WP installation concurrently with a WP domain, e.g. myportfolio.wordpress.com, will the site be more or less likely to be indexed rather a generic myportfolio.com domain? I've seen mixed opinions where people seem to favor a WP domain for URL output where others say that it's a moot point, and that Google will not favor a WP domain over a dot com domain as long as your meta tags are updated and content is keyword optimized. I tend to disagree and believe a WP domian would more likely be indexed and output more URLs over an individual, laconic domain like myportfolio.com. Am I wrong? Thanks in advance!

• Windows W8, L8 and now H8

  - by raccoon_tim

  Windows 8 is having to endure with a lot of headwind at the moment. The weather forecast doesn’t appear to improve in the near future either with prominent game developers and publishers taking to the barricades accusing Microsoft of building a closed ecosystem. I am forced to side with this opinion as I too see services the likes of Steam as playing an important role in the gaming world, which just happens to be an industry that cannot be sidelined. What Microsoft is attempting to do is merge the PC and mobile markets. The Windows Marketplace is to be the only place where you can purchase Windows applications in the future starting now with Metro apps. This is what Apple, Google and Microsoft have been doing with mobile devices for some time now and it’s what we have all come to expect. The PC market is different, however. It has always been open, which has resulted in a diverse market allowing for third parties to build successful distribution and marketing networks. You could argue that Microsoft is just doing something that Steam has been doing for a long time now but the difference is that Microsoft would own both the marketplace AND that operating system, which would eventually give it dominance over the whole Windows application distribution network. Currently there is no real alternative to Windows in the PC gaming world but I would expect to see Mac OS and Linux getting more popular if Microsoft does not notice the signals coming from the gaming industry and choose to once again open up the markets on the PC.

• How should oracle vbox look like in terms of Memory, CPU and Performance? [duplicate]

  - by Nicholas DiPiazza

  This question already has an answer here: Can you help me with my capacity planning? 2 answers I've got a need for a ton of VMs to simulate some realistic load testing scenarios. I've got a bunch of different host machines that differ in ram, cpu's, etc. What should my resource manager look like? Is there a standard way to know what the CPU, Memory and Disk Utilization should be given your CPUs + Memory available + Disks available? For example, I have a box: MemTotal: 50 Gb CPUs: 8 CPUs are pretty much 100% all day long. Memory is at about 60%. Swap not getting hit. Little bewildered by why the VMs, while doing the exact same test script, are showing different virtual memory consumption. Huh.

• &ldquo;Why do transactional messages all have the same priority?&rdquo;

  - by John Breakwell

  I answered this question on the MSMQ forum on MSDN and thought it worth sharing here. The poster wanted to know why all transactional messages have a fixed priority of zero (instead of 0 through 7). They wanted the guaranteed delivery of messages to a queue but wanted to assign different levels of priority. Some aspects of MSMQ were defined way back in the last century and this is one of them. If I remember right, the reason was to avoid the following scenario: You have a single transaction of 3 messages (a, b and c) with priorities 5, 3 and 4 respectively. The messages are sent in order a,b,c The messages arrive in the queue and are arranged in order a,c,b to reflect priority order This breaks the guaranteed order part of the transaction.  I know that very few people send more than one message in a transaction but that is a scenario that MSMQ has to be able to handle; for the majority, including yourself, this scenario is irrelevant which is why you are surprised by the absence of transactional priorities. The options, therefore, available to the Microsoft developers were to: Implement code that allowed you to send messages with variable priority as long as any messages within the same transaction were the same priority, or Define a set priority for all transactional messages As you can understand, option 1 would be a complicated arrangement with all the necessary enforcement, error handling, user education and documentation, etc. Sure, it would have been possible to implement option 1 but I expect the product group decided to invest the development time in some other aspect of MSMQ. Now, with five versions out there, it would be confusing to change how the product operates, in addition to potentially breaking exisiting systems that have been working fine for years. So, balancing cost and risk against customer demand, I would not expect this feature to ever change.

• Hide/Unhide rows based on more than one cell value

  - by Mike

  Please help me I am using the following code to hide rows if cell values are 0: Private Sub Worksheet_Calculate() Dim LastRow As Long, c As Range Application.EnableEvents = False LastRow = Cells(Cells.Rows.Count, "I").End(xlUp).Row On Error Resume Next For Each c In Range("I9:I48") If c.Value = 0 Then c.EntireRow.Hidden = True ElseIf c.Value > 0 Then c.EntireRow.Hidden = False End If Next On Error GoTo 0 Application.EnableEvents = True End Sub It works perfectly, but I would like for the code to also check column K (the same range K9:K48) if both cells in a row are 0 then the row must be hidden. How can I change the code to do this?

• How do you assign resources and keep begin, end and duration of a task intact?

  - by Random

  I have problems with assigning more than one resource to a group of tasks. The idea is simple, my tasks are in one group and are manually scheduled to particular begin and end dates. I want to assign more than one resource to keep task duration and dates (fixed duration) and increase work. For top level tasks it works fine but as long tasks are grouped, the duration of each is extended to reach group end date and work remains. For the problematic tasks, the Gantt chart looks like this: One resource attached (good) ( Task 1.1 ) ( Task 1.2 ) (Task 1.3) More than one resource attached (wrong) ( Task 1.1 )....................... ( Task 1.2 ).......... (Task 1.3) So for tasks like that, I want to have a fixed schedule and just increase work by adding resources that work in the same time, but sometimes MS Project does leveling to do resources work sequentialy.

• How to force "Windows Explorer" to open new folders in the same window

  - by yoshiserry

  I have been searching for an answer to this question for a very long time. I have checked the "open folders in the same window" radio button in the general tab of folder options. I have also been told to uncheck the launch as seperate processes button in the view tab of folder options. I'm thinking some how this must be a registry issue. Anyone know a registry hack that will fix this problem and force windows explorer to open folders in the same window. I'm sick to death of having so many windows open. Im running Windows 7 Ultimate Beta 7100.

• Why Does My Laptop Freeze Up When Docked?

  - by Michael Haren

  I have a Dell Latitude D520. First with Windows XP and now with Windows 7, it completely freezes/locks up if I dock it while it's awake. If I hibernate/sleep, dock, then wake/resume, everything's fine. I installed the Dell Notebook System Software for Vista (No Win7 version available) and updated the bios to the latest version but the problem persists. As long as I remember to put this thing in standby before I dock it, it's extremely reliable--it survives my daily commute and heavy use and typically only reboots a few times a month. Any other ideas for things I can try?

• Scaling sprite velocity / co-ordinatesin Android

  - by user22241

  I'm trying to find the answer to a question that I've had for a long time, but am having trouble finding it! I hope someone can help :-) I'm trying to find information on how to scale sprite velocity / movement / co-ordinates. What I mean by this is how do I get a sprite to move at the same speed relative to the screen size / DPI so that it takes the same amount of real-time to get from one side of the screen to the other? All of the posts pertaining to sprite scaling that I can find on the various forums relate to the size of the sprite, but this part of it I'm OK with so far, it's just that when I move a sprite, it kind of gets there at different speed depending on the dpi / resolution of the device. I hope I'm making sense. This is the code I have so far, instead of using explicit amounts, like 1, I'm using something like the following: platSpeedFloat= (1 * (dpi/160)); //Use '1' so on an MDPI screen, the sprite will move by 1 physical pixel Then basically what I'm doing is something like this: (all varialble previously declared) platSpeedSave+=platSpeedFloat; //Add the platSpeedFloat value to the current platSpeedSave value platSpeed=(int) platSpeedSave; //Cast to int so it can be checked in the following statement if (platSpeed==platSpeedSave) //Check the casted int value to float value stored previoiusly {floorY=floorY-platSpeed; //If they match then change the Y value platSpeedSave=0;} //Reset Would be grateful if someone could assists - hope I'm making sense. The above doesn't seems to work the sprite moves 'faster' on lower DPI screens. Thanks

• Iterative and Incremental Principle Series 5: Conclusion

  - by llowitz

  Thank you for joining me in the final segment in the Iterative and Incremental series.  During yesterday’s segment, I discussed Iteration Planning, and specifically how I planned my daily exercise (iteration) each morning by assessing multiple factors, while following my overall Implementation plan. As I mentioned in yesterday’s blog, regardless of the type of exercise or how many increment sets I decide to complete each day, I apply the 6 minute interval sets and a timebox approach.  When the 6 minutes are up, I stop the interval, even if I have more to give, saving the extra energy to apply to my next interval set.   Timeboxes are used to manage iterations.  Once the pre-determined iteration duration is reached – whether it is 2 weeks or 6 weeks or somewhere in between-- the iteration is complete.  Iteration group items (requirements) not fully addressed, in relation to the iteration goal, are addressed in the next iteration.  This approach helps eliminate the “rolling deadline” and better allows the project manager to assess the project progress earlier and more frequently than in traditional approaches. Not only do smaller, more frequent milestones allow project managers to better assess potential schedule risks and slips, but process improvement is encouraged.  Even in my simple example, I learned, after a few interval sets, not to sprint uphill!  Now I plan my route more efficiently to ensure that I sprint on a level surface to reduce of the risk of not completing my increment.  Project managers have often told me that they used an iterative and incremental approach long before OUM.   An effective project manager naturally organizes project work consistent with this principle, but a key benefit of OUM is that it formalizes this approach so it happens by design rather than by chance.    I hope this series has encouraged you to think about additional ways you can incorporate the iterative and incremental principle into your daily and project life.  I further hope that you will share your thoughts and experiences with the rest of us.

• How can I send SMS from my PC using my Android Phone (Galaxy S3)

  - by Dean Rather

  I've been a long-time Nokia fan, but finally succumbed to the Samsung Galaxy S3's amazing screen, & Android's Open community. One feature I use a lot (about a hundred times a day...) is Nokia PC Suite's ability to send SMS via the phone. It: Uses my phone's contact list. Notifies me when I get an sms. Allows me to send SMS using my PC's keyboard. Essentially turning SMS into just another IM medium I use on the PC. How will I do this with the Samsung Galaxy S3 + Windows 7?
