Windows Server 2008 R2 automated reboot everyweek

- by Jean-François Rioux

I'm rather new with Windows / Windows server administration. I heard that rebooting Windows servers everyweek is required to keep it functioning well. So here, we reboot every Virtual Machine running Windows everyday at a specified time, automatically. Coming from a Unix background, I find that rather surprising. But since I don't know much about Windows (actually, I know absolutely nothing about managing Windows Servers) , I was wondering, is there really a use for that? Thank you,

How long do uploaded files stay in the tmp folder in Linux Ubuntu?

- by Jean-Nicolas Boulay Desjardins

I am building a web application where my users will be able to upload files. After the files are uploaded I need to send the files to two other servers, and after they will be deleted from the server where they were just uploaded to. I am wandering is it a good I idea to keep the uploaded files in the tmp/ folder the time the uploaded files are sent to the other two servers or should I move them to another folder incase they get deleted? I am also wandering because I would like to know if I have to build a cron script to get rid of the files that have been transfered to the other servers so that I get my disk space back.

Script on startup without update-rc.d

- by Jean-Philippe Blary

I've a debian minimal installation, and I just want to start a script at startup. So, I've a script at /etc/init.d/myscript, I put a chmod 700, and create symlinks ('S20myscript') into /etc/rc2.d, rc3.d, rc4.d and rc5.d. But the script is NOT launched at all. When I put this script with update-rc.d (or insserv...), it works. I don't understand, am I forced to use this command? (and no, I don't want to use /erc/rc.local). Thanks!

How can I protect files on my NGiNX server?

- by Jean-Nicolas Boulay Desjardins

I am trying to protect files on my server (multiple types), with NGiNX and PHP. Basically I want people to have to sign in to the website if they want to access those static files like images. DropBox does it very well. Where by they force you to sign in to access any static files you put on there server. I though about using NGiNX Perl Module. And I would write a perl script that would check the session to see if the user was sign in to give them access to a static file. I would prefer using PHP because all my code is running under PHP and I am not sure how to check a session created by PHP with PERL. So basically my question is: How can I protect static files of any types that would need the user to have sign in and have a valid session created with a PHP script?

How to install a proxy LDAP

- by Jean-Claude

I have to install an LDAP proxy on a compute cluster frontend. The idea is to avoid the compute nodes to make too many requests on the campus LDAP server. How can I install this to make it work with the school's LDAP? The frontend OS is a RHEL 6.2. I found that I have to install the LDAP server and configure it as a proxy. But all I can find is examples of /etc/openldap/slapd.conf file configuration but after testing different configuration, no results. Furthermore, according to RHEL 6 - Deployment Guide, this config file is obsolete: OpenLDAP no longer reads its configuration from the /etc/openldap/slapd.conf file. Instead, it uses a configuration database located in the /etc/openldap/slapd.d/ directory. Any help is welcomed. Thank you

bootmgr is missing on Toshiba laptop with Windows 7

- by jean

I have a Toshiba laptop with Windows 7 on it. As soon as I turn my computer on it says bootmgr is missing The only thing I can get into is the setup menu. Does anyone know what might be wrong? My step brother thinks that it might be that everything was erased off my hard drive. The last thing he did when he used it was to perform the Toshiba updates and restart the computer. If anyone knows what might be wrong or how I could get my computer up and running please let me know.

Potential issues using member's "from" address and the "sender" header

- by Paul Burney

Hi all, A major component of our application sends email to members on behalf of other members. Currently we set the "From" address to our system address and use a "Reply-to" header with the member's address. The issue is that replies from some email clients (and auto-replies/bounces) don't respect the "Reply-to" header so get sent to our system address, effectively sending them to a black hole. We're considering setting the "From" address to our member's address, and the "Sender" address to our system address. It appears this way would pass SPF and Sender-ID checks. Are there any reasons not to switch to this method? Are there any other potential issues? Thanks in advance, -Paul Here are way more details than you probably need: When the application was first developed, we just changed the "from" address to be that of the sending member as that was the common practice at the time (this was many years ago). We later changed that to have the "from" address be the member's name and our address, i.e., From: "Mary Smith" <[email protected]> With a "reply-to" header set to the member's address: Reply-To: "Mary Smith" <[email protected]> This helped with messages being mis-categorized as spam. As SPF became more popular, we added an additional header that would work in conjunction with our SPF records: Sender: <[email protected]> Things work OK, but it turns out that, in practice, some email clients and most MTA's don't respect the "Reply-To" header. Because of this, many members send messages to [email protected] instead of the desired member. So, I started envisioning various schemes to add data about the sender to the email headers or encode it in the "from" email address so that we could process the response and redirect appropriately. For example, From: "Mary Smith" <[email protected]> where the string after "messages" is a hash representing Mary Smith's member in our system. Of course, that path could lead to a lot of pain as we need to develop MTA functionality for our system address. I was looking again at the SPF documentation and found this page interesting: http://www.openspf.org/Best_Practices/Webgenerated They show two examples, that of evite.com and that of egreetings.com. Basically, evite.com is doing it the way we're doing it. The egreetings.com example uses the member's from address with an added "Sender" header. So the question is, are there any potential issues with using the egreetings method of the member's from address with a sender header? That would eliminate the replies that bad clients send to the system address. I don't believe that it solves the bounce/vacation/whitelist issue since those often send to the MAIL FROM even if Return Path is specified.

asp.net Multiple Page_Load events for a user control when using URL Routing

- by Paul Hutson

Hello, I've recently set up an ASP.net site (not using MVC.net) to use URL Routing (more on the code below) - when using user controls on the site (i.e I've created a "menu" user control to hold menu information) the page_load event for that control will fire twice when URLs have more than one variable passed over. i.e. pageName/VAR1 : will only fire the page_load event once. while pageName/VAR1/VAR2 : will fire the page_load event twice. *Multiple extra VARs added on the end will still only fire the page_load event twice*. Below are the code snippits from the files, the first is the MapPageRoute, located in the Global.asax : // Register a route for the Example page, with the NodeID and also the Test123 variables allowed. // This demonstrates how to have several items linked with the page routes. routes.MapPageRoute( "Multiple Data Example", // Route name "Example/{NodeID}/{test123}/{variable}", // Route URL - note the NodeID bit "~/Example.aspx", // Web page to handle route true, // Check for physical access new System.Web.Routing.RouteValueDictionary { { "NodeID", "1" }, // Default Node ID { "test123", "1" }, // Default addtional variable value { "variable", "hello"} // Default test variable value } ); Next is the way I've directed to the page in the menu item, this is a list item within a UL tag : <li class="TopMenu_ListItem"><a href="<%= Page.GetRouteUrl("Multiple Data Example", new System.Web.Routing.RouteValueDictionary { { "NodeID", "4855" }, { "test123", "2" } }) %>">Example 2</a></li> And finally the control that gets hit multiple times on a page load : // For use when the page loads. protected void Page_Load(object sender, EventArgs e) { // Handle the routing variables. // this handles the route data value for NodeID - if the page was reached using URL Routing. if (Page.RouteData.Values["NodeID"] != null) { nodeID = Page.RouteData.Values["NodeID"] as string; }; // this handles the route data value for Test123 - if the page was reached using URL Routing. if (Page.RouteData.Values["Test123"] != null) { ExampleOutput2.Text = "I am the output of the third variable : " + Page.RouteData.Values["Test123"] as string; }; // this handles the route data value for variable - if the page was reached using URL Routing. if (Page.RouteData.Values["variable"] != null) { ExampleOutput3.Text = "I say " + Page.RouteData.Values["variable"] as string; }; } Note, that when I'm just hitting the page and it uses the default values for items, the reloads do not happen. Any help or guidance that anyone can offer would be very much appreciated! EDIT : The User Control is only added to the page once. I've tested the load sequence by putting a breakpoint in the page_load event - it only hits twice when the extra routes are added. Thanks in Advance, Paul Hutson

Is it possible to print on a networked Windows Print server from an AIX server, without using remote

- by Stringent Software

I have an application on an AIX server (v5.3) that needs to print via a Windows Print Server over the LAN. The simplest way to do this is to use SMIT to setup a remote print queue - which I've done on the test environment - but the IT department have refused to set up a remote print queue on the Production server. I don't have root access to the Production server. Is there any other method for connecting the app to the print server that doesn't involve print queues on the AIX box?

What 5 things should SQL Server get rid of?

- by BuckWoody

I’ve been “tagged” by my friend Paul Randal. It’s a high-tech way of making someone else do what you want, but since it’s Paul, well, I guess I’m OK with that. He’s asked in his recent blog entry “What five things would you get rid of in SQL Server if you were in charge?” This is, of course, a delicate issue. After all, I work at Microsoft, so anything I say here might be taken as a criticism that would require action – but of course it really doesn’t. Interestingly, you may have more to do with what goes in to SQL Server than I did even as a Program Manager where I “owned” a feature. Unlike many places I’ve worked, Microsoft really does drive its products by what its users want – not every time, and not every user request, mind you, but overall I think we hit the mark pretty well. So, with all of that said, and of course the obligatory statement of “these are my own opinions, and have nothing to do with any official Microsoft position in any way, and do not reflect the opinions of other Microsoft employees or management”, here goes. 1. Get rid of SQL Server Management Studio Does that surprise you? After all, when I was a Program Manager, I actually owned the general architecture for SSMS. But those on my team probably would have been able to guess this one for you. I think that SSMS is a fine development tool. But I think that it does less of a good job for managing a system. It’s based on Visual Studio, probably one of the best development IDE’s around. And when I develop code, I really like it. But for a monitoring/management tool, I prefer a snap-in to the Microsoft Management Console (MMC). I know, the old one (prior to 3.0) was kludgy, difficult to use and program in. But that’s changed. Of course, when I bring this up, you’ll probably immediately say “But I don’t have that in XP.” And that’s one of the reasons we didn’t go there. (But I still don’t like SSMS for management.) 2. ShrinkDB I think this discussion has been done to death, so I’ll leave it at that. 3. SQL Server Agent Does that one surprise you as well? In my mind, since we ALWAYS ride on Windows, just use the task scheduler there, along with PowerShell. You could log the results in Windows logs, files, back into SQL Server, whatever. It’s just a complexity we don’t need in SQL Server. 4. SQL Server Error Logs We have a full logging setup in Windows. They’re well done, easy to understand and ubiquitous. We should just use that. 5. Several SKU’s I won’t say which, but we have a few SKU’s of SQL Server that need to go. And we need to figure out how to help you understand clearly where you need to go to Enterprise or Data Center. Most folks are trying to push Standard edition to do things it isn’t designed to do, and then they think SQL Server won’t scale. I think we can do a better job of showing you where Standard Edition will hit the wall, and I think with fewer choices it would be pretty simple for you to pick the right one. Well, once again I’ve probably puzzled some folks and angered others. I think my work here is done. :) Back to you, Paul.

SQL Syntax to count unique users completing a task

- by Belliez

I have the following code which shows me what users has completed ticket and this lists each user and the date they close a ticket. i.e. Paul Matt Matt Bob Matt Paul Matt Matt At the moment I manually count each user myself to see their totals for the day. EDIT: Changed output as columns instead of rows: What I have been trying to do is get SQL Server to do this for me i.e. the final result to look like: Paul | 2 Matt | 5 Bob | 1 My code I am currently using is and I would be greatful if someone can help me change this so I can get it outputting something similar to above? DECLARE @StartDate DateTime; DECLARE @EndDate DateTime; -- Date format: YYYY-MM-DD SET @StartDate = '2013-11-06 00:00:00' SET @EndDate = GETDATE() -- Today SELECT (select Username from Membership where UserId = Ticket.CompletedBy) as TicketStatusChangedBy FROM Ticket INNER JOIN TicketStatus ON Ticket.TicketStatusID = TicketStatus.TicketStatusID INNER JOIN Membership ON Ticket.CheckedInBy = Membership.UserId WHERE TicketStatus.TicketStatusName = 'Completed' and Ticket.ClosedDate >= @StartDate --(GETDATE() - 1) and Ticket.ClosedDate <= @EndDate --(GETDATE()-0) ORDER BY Ticket.CompletedBy ASC, Ticket.ClosedDate ASC Thank you for your help and time.

Aggregate survey results recursively by manager

What I am trying to do sounds pretty simple but I am struggling to find a neat, quick way of doing it. I want to create a sproc that takes an Srn and returns back all the staff under that Srn in the structure. If there is a score for QuestionId of 16 then that indicates a completed survey. I would like to return a line for the Srn entered (The top manager) with a count of completed surveys for the direct reports under that manager. Under that I would like each manager under the original manager with a count of completed surveys for each of their direct reports and so on. I would like to see the data as such below when I set the top manager to be Joe (ABC2). UserName | Completed | Total ============================ Joe | 2 | 2 Paul | 1 | 2 David | 0 | 2 TOTAL | 3 | 6

SQL View with Data from two tables

- by Alex

Hello! I can't seem to crack this - I have two tables (Persons and Companies), and I'm trying to create a view that: 1) shows all persons 2) also returns companies by themselves once, regardless of how many persons are related to it 3) orders by name across both tables To clarify, some sample data: (Table: Companies) Id Name 1 Banana 2 ABC Inc. 3 Microsoft 4 Bigwig (Table: Persons) Id Name RelatedCompanyId 1 Joe Smith 3 2 Justin 3 Paul Rudd 4 4 Anjolie 5 Dustin 4 The output I'm looking for is something like this: Name PersonName CompanyName RelatedCompanyId ABC Inc. NULL ABC Inc. NULL Anjolie Anjolie NULL NULL Banana NULL Banana NULL Bigwig NULL Bigwig NULL Dustin Dustin Bigwig 4 Joe Smith Joe Smith Microsoft 3 Justin Justin NULL NULL Microsoft NULL Microsoft NULL Paul Rudd Paul Rudd Bigwig 4 As you can see, the new "Name" column is ordered across both tables (the company names appear correctly in between the person names), and each company appears exactly once, regardless of how many people are related to it. Can this even be done in SQL?! P.S. I'm trying to create a view so I can use this later for easy data retrieval, fulltext indexing and make the programming side simpler by just querying the view.

Getting an invalidoperationexception when deserialising XML

- by Paul Johnson

Hi, I'm writing a simple proof of concept application to load up an XML file and depending on the very simple code, create a window and put something into it (it's for a much larger project). Due to limitations in Mono, I'm having to run in this way. The code I currently have looks like this using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Windows.Forms; using System.IO; using System.Collections; using System.Xml; using System.Xml.Serialization; namespace form_from_xml { public class xmlhandler : Form { public void loaddesign() { FormData f; f = null; try { string path_env = Path.GetDirectoryName(Application.ExecutablePath) + Path.DirectorySeparatorChar; // code dies on the line below XmlSerializer s = new XmlSerializer(typeof(FormData)); TextReader r = new StreamReader(path_env + "designer-test.xml"); f = (FormData)s.Deserialize(r); r.Close(); } catch (System.IO.FileNotFoundException) { MessageBox.Show("Unable to find the form file", "File not found", MessageBoxButtons.OK); } } } [XmlRoot("Forms")] public class FormData { private ArrayList formData; public FormData() { formData = new ArrayList(); } [XmlElement("Element")] public Elements[] elements { get { Elements[] elements = new Elements[formData.Count]; formData.CopyTo(elements); return elements; } set { if (value == null) return; Elements[] elements = (Elements[])value; formData.Clear(); foreach (Elements element in elements) formData.Add(element); } } public int AddItem(Elements element) { return formData.Add(element); } } public class Elements { [XmlAttribute("formname")] public string name; [XmlAttribute("winxsize")] public int winxs; [XmlAttribute("winysize")] public int winys; [XmlAttribute("type")] public object type; [XmlAttribute("xpos")] public int xpos; [XmlAttribute("ypos")] public int ypos; [XmlAttribute("externaldata")] public bool external; [XmlAttribute("externalplace")] public string externalplace; [XmlAttribute("text")] public string text; [XmlAttribute("questions")] public bool questions; [XmlAttribute("questiontype")] public object qtype; [XmlAttribute("numberqs")] public int numberqs; [XmlAttribute("answerfile")] public string ansfile; [XmlAttribute("backlink")] public int backlink; [XmlAttribute("forwardlink")] public int forwardlink; public Elements() { } public Elements(string fn, int wx, int wy, object t, int x, int y, bool ext, string extpl, string te, bool q, object qt, int num, string ans, int back, int end) { name = fn; winxs = wx; winys = wy; type = t; xpos = x; ypos = y; external = ext; externalplace = extpl; text = te; questions = q; qtype = qt; numberqs = num; ansfile = ans; backlink = back; forwardlink = end; } } } With a very simple xmlhandler xml = new xmlhander(); xml.loaddesign(); attached to a winform button. Everything is in the same namespace and the xml file actually exists. This is annoying me now - can anyone spot the error of my ways? Paul

Add options to select box without Internet Explorer closing the box?

- by Paul Colby

Hi, I'm trying to build a web page with a number of drop-down select boxes that load their options asynchronously when the box is first opened. This works very well under Firefox, but not under Internet Explorer. Below is a small example of what I'm trying to achieve. Basically, there is a select box (with the id "selectBox"), which contains just one option ("Any"). Then there is an onmousedown handler that loads the other options when the box is clicked. <html> <head> <script type="text/javascript"> function appendOption(select,option) { try { selectBox.add(option,null); // Standards compliant. } catch (e) { selectBox.add(option); // IE only version. } } function loadOptions() { // Simulate an AJAX request that will call the // loadOptionsCallback function after 500ms. setTimeout(loadOptionsCallback,500); } function loadOptionsCallback() { var selectBox = document.getElementById('selectBox'); var option = document.createElement('option'); option.text = 'new option'; appendOption(selectBox,option); } </script> </head> <body> <select id="selectBox" onmousedown="loadOptions();"> <option>Any</option> </select> </body> </html> The desired behavior (which Firefox does) is: the user see's a closed select box containing "Any". the user clicks on the select box. the select box opens to reveal the one and only option ("Any"). 500ms later (or when the AJAX call has returned) the dropped-down list expands to include the new options (hard coded to 'new option' in this example). So that's exactly what Firefox does, which is great. However, in Internet Explorer, as soon as the new option is added in "4" the browser closes the select box. The select box does contain the correct options, but the box is closed, requiring the user to click to re-open it. So, does anyone have any suggestions for how I can load the select control's options asynchronously without IE closing the drop-down box? I know that I can load the list before the box is even clicked, but the real form I'm developing contains many such select boxes, which are all interrelated, so it will be much better for both the client and server if I can load each set of options only when needed. Also, if the results are loaded synchronously, before the select box's onmousedown handler completes, then IE will show the full list as expected - however, synchronous loading is a bad idea here, since it will completely "lock" the browser while the network requests are taking place. Finally, I've also tried using IE's click() method to open the select box once the new options have been added, but that does not re-open the select box. Any ideas or suggestions would be really appreciated!! :) Thanks! Paul.

using ajax to post comments in cakephp results in 404 error, but no errors locally?

- by Paul

Using an ajax helper created for use with Jquery I've created a form that posts comments to "/comments/add", and this works as expected on my local wamp server but not on my production server. On my production server I get a '404 error, cannot find /comments/add'. I've spent quite a bit of time searching for a resolution with no luck so far. I've focused on trying to identify a gap but nothing jumps out at me. Here are some observations: works as expected on local wamp server requestHandler is listed as component files on both local and production server are the same controllers folder has write access autoLayout and autoRender are both set to false Here is the form in my view: <div class="comments form"> <?php echo $ajax->form('/comments/add', 'tournament', array('url' => '/comments/add', 'update' => 'Comments', 'indicator' => 'commentSaved'));?> <fieldset> <legend><?php __('Add Comment');?></legend> <div id="commentSaved" style="display: none; float: right;"> <h2>Loading...</h2> </div> <?php echo $form->hidden('Comment.foreign_id', array('value' => $tournament['Tournament']['id'])); echo $form->hidden('Comment.belongs_to', array('value' => 'Tournament')); echo $form->input('Comment.name'); echo $form->input('Comment.email'); echo $form->input('Comment.web', array('value' => 'http://')); echo $form->input('Comment.content'); ?> </fieldset> <?php echo $form->end('Submit');?> </div> And here is my 'comment's controller add action: function add() { if($this->RequestHandler->isAjax()) { $this->autoLayout = false; $this->autoRender=false; $this->Comment->recursive =-1; $commentInfos = $this->Comment->findAllByIp($_SERVER['REMOTE_ADDR']); $spam = FALSE; foreach($commentInfos as $commentInfo) { if ( time() - strtotime($commentInfo['Comment']['created']) < 180) { $spam = TRUE; } } if ($spam === FALSE) { if (!empty($this->data)) { $this->data['Comment']['ip'] = $_SERVER['REMOTE_ADDR']; $this->Comment->create(); if ($this->Comment->save($this->data)) { $this->Comment->recursive =-1; $comments = $this->Comment->findAll(array('Comment.foreign_id' => $this->data['Comment']['foreign_id'], 'Comment.belongs_to' => $this->data['Comment']['belongs_to'], 'Comment.status' =>'approved')); $this->set(compact('comments')); $this->viewPath = 'elements'.DS.'posts'; $this->render('comments'); } } } else { $this->Comment->recursive =-1; $comments = $this->Comment->findAll(array('Comment.foreign_id' => $this->data['Comment']['foreign_id'], 'Comment.belongs_to' => $this->data['Comment']['belongs_to'], 'Comment.status' =>'approved')); $this->set(compact('comments')); $this->viewPath = 'elements'.DS.'posts'; $this->render('spam'); } } else { $this->Session->setFlash(__('Invalid Action. Please view a post to add a comment.', true)); $this->redirect(array('controller' => 'pages', 'action'=>'display', 'home')); } } As you can see I've made sure that 'autoLayout' and 'autoRender' are set to false, but in Firebug I still get a 404 error stating /comments/add cannot be found on the production server. I should also point out that I'm using jquery, jquery.form and jquery.editable as well as a ajax helper created to be used with jquery. Any help or even suggestions about how to trouble shoot this is really appreciated. Cheers, Paul

Programming concepts taken from the arts and humanities

- by Joey Adams

After reading Paul Graham's essay Hackers and Painters and Joel Spolsky's Advice for Computer Science College Students, I think I've finally gotten it through my thick skull that I should not be loath to work hard in academic courses that aren't "programming" or "computer science" courses. To quote the former: I've found that the best sources of ideas are not the other fields that have the word "computer" in their names, but the other fields inhabited by makers. Painting has been a much richer source of ideas than the theory of computation. — Paul Graham, "Hackers and Painters" There are certainly other, much stronger reasons to work hard in the "boring" classes. However, it'd also be neat to know that these classes may someday inspire me in programming. My question is: what are some specific examples where ideas from literature, art, humanities, philosophy, and other fields made their way into programming? In particular, ideas that weren't obviously applied the way they were meant to (like most math and domain-specific knowledge), but instead gave utterance or inspiration to a program's design and choice of names. Good examples: The term endian comes from Gulliver's Travels by Tom Swift (see here), where it refers to the trivial matter of which side people crack open their eggs. The terms journal and transaction refer to nearly identical concepts in both filesystem design and double-entry bookkeeping (financial accounting). mkfs.ext2 even says: Writing superblocks and filesystem accounting information: done Off-topic: Learning to write English well is important, as it enables a programmer to document and evangelize his/her software, as well as appear competent to other programmers online. Trigonometry is used in 2D and 3D games to implement rotation and direction aspects. Knowing finance will come in handy if you want to write an accounting package. Knowing XYZ will come in handy if you want to write an XYZ package. Arguably on-topic: The Monad class in Haskell is based on a concept by the same name from category theory. Actually, Monads in Haskell are monads in the category of Haskell types and functions. Whatever that means...
