• Adding Windows 7 to grub4dos menu.lst

  - by antonio

  I am trying to create a multiboot USB drive with grub4dos. I started with a working bootable WinPE-like USB drive, based on Windows 7. I modified the drive MBR with grubinst.exe (hd1), copied in its root grldr and the menu menu.lst file: color blue/green yellow/red white/magenta white/magenta timeout 30 default 0 title Win 7 test rootnoverify (hd0, 0) chainloader /bootmgr I get the error: Try (hd0, 0). This partition is ntfs but with unknown boot record Try (hd0, 1) ... ... Cannot find GRLDR. If I hit a key, anyway it boots Windows 7. I would like to drop to the GRUB command shell, but when I hit "c" Grub boots into Windows.

• BDD (Behavior-Driven Development) tools for .Net

  - by tikrimi

  For several years, I use TDD (Test-Driven Development) to produce code. I no longer plans to work without using TDD. The use of TDD significantly increases code quality, but does not guarantee that the code is the code that corresponds to the requirements specifications (write the "right code" with BDD as opposed to the write "code right" with BDD). Dan North has described in an article in published in 2006 the foundations of the BDD (Behavior-Driven Development). In this article, he introduces the formalism "When Given Then". This formalism is used in all tools dedicated to BDD. This is a short list of open source BDD tools that you can use with .Net : SpecFlow: Here you can find an article in MSDN Magazine and 2 webcasts (http://channel9.msdn.com/posts/ASPNET-MVC-With-Community-Tools-Part-2-Spec-Flow-and-WatiN and http://channel9.msdn.com/posts/ASPNET-MVC-With-Community-Tools-Part-3-More-Spec-Flow-and-WatiN) published on Chanel9. NSpec: This is certainly the most used project. There are many examples on the web. StoryQ: This project is hosted on Codeplex. This small project is very simple to implement and very useful.

• Knowledge Pathways Designer - Recommended Settings

  - by ted.henson

  The General page of the Options dialog box contains the application preferences for Knowledge Pathways Designer. It is recommended that you leave certain settings as they are, unless you have a specific reason for changing them. The following are a few of the settings on the General page with an explanation of the recommended setting. They are in the order they appear on the page: Allow version 2.0 style links: This option should remain disabled unless you were using content that was created using version 2.0 of Knowledge Pathways and you want the same linking functionality that existed in that version 2.0. This feature enables you to reuse parts of titles that contain no AUs. However, keep in mind that this type of link is not a true link, but a cross between a copy and a link. To create a 2.0 style link, you drag and drop sections between titles. You can only create 2.0 style links to sections that belong to the Title AU. When creating a version 2.0 style link, your mouse pointer will change to indicate a 2.0 link is being created. Confirm deletion of outline items and Confirm deletion of titles: It is recommended that these options remain enabled to avoid deleting something by accident. Display tracking data loss warning when opening a published title: It recommended that this option be enabled so you will receive the warning message when you open the development copy of a title, reminding you of the implications of your changes. ulCopy files when converting a Section to an Assignable Unit: This option should remain enabled unless you have a specific reason for not copying the files. If this is disabled, you will (in effect) lose your content files upon converting because they will not be copied to the new AU directory on the content root. In this case, you would need to use Windows Explorer to copy your files manually. Working with Spelling Options All of the spelling options are enabled by default. Your design team can review these options to determine if you want to make changes, depending upon your specific needs. Understanding Dictionary Options You should leave the dictionary options as they are, unless you have a specific reason for changing them. While you can delete the user (customizable) dictionary, doing so is not recommended. Setting Check In/Check Out Options The ability to check in and check out titles and AUs will impact the efficiency of your design team. Decide what your check in and check out processes are before you start developing titles. The Check In/Check Out page of the Options dialog box contains two options that affect what happens when you open a title using the Open Title dialog box. Both of these options are enabled by default and are described below: Check Out for editing enabled: This option ensures that the Check Out for editing option will be selected when you open the development copy of a title from the Open Title dialog box. If this option is disabled, you must select the Check Out for editing option every time you want to check out a title for editing. Attempt to Check Out for entire branch: When this option is enabled, Designer checks out the selected title and all AUs and sections that are part of that title, provided they are available for check out. If this option is disabled, you will only check out the Title AU and anything that belongs to that Title AU (e.g., sections, questions, etc.), but not other AUs. The Check In/Check Out page of the Options dialog box also contains options that control what happens when you close a title. You can choose one option in the Check In when Closing a Title area. The option selected is a matter of preference and you should determine which option is most appropriate for your design team.

• Is there a way to create a copy-on-write copy of a directory?

  - by BCS

  I'm thinking of a situation where I would have something that creates a copy of a directory, tweaks a few files, and then does some processing on the result. This wold be done fairly often, maybe a few dozen times a day. (The exact use case is testing patch submissions; dupe the code, patch it, build/test/report/etc.) What I'm looking for could be done by creating a new directory structure and populating it with hard links from the origonal. However this only works if all the tools you use delete and recreate files rather than edit them in place. Is there a way to have the file system do copy-on-write for a file? Note: I'm aware that many FSs use COW at a block level (all updates are done via writes to new blocks) but this is not what I want.

• Storing multipe credentials for the same server.

  - by EmFi

  I have a need to connect to the same exchange server with multiple accounts. I'm using Extra Outlook to simultaneously load different profiles connecting to each account. Here's a simplified example of the accounts I need to use: log in to test.local.domain user1: [email protected] user2: [email protected] user3: [email protected] I am always being prompted for passwords when opening an Outlook instance. Essentialy only the last username/password combination for each server is stored by Vista. So if I launch Outlook with the same profile I used last, before starting launching using a profile for a different account, I'm not prompted for authentication. Aternatively, adding a new entry in Vista's Stored User Names and Passwords dialog with credentials for user2, when there is alraedy an entry for user1 on the same target server will replace the existing user1 entry with the new user 2 entry. I'm guessing the same thing is going on silently behind the scenes when I provide Outlook credentials. How can I configure Vista's credential management to store credentials for multiple users on the same server?

• How to install OpenOffice 3.1 in Headless Mode?

  - by Geo

  I need to setup OpenOffice in a linux box that will never have X installed. Every time I run the setup program of the OpenOffice installer it complains that the system does not have an X Terminal. I am using OOo_3.1.0_LinuxIntel_install_wJRE_en-US.tar. I have done this headless install for version 2.4, but we are having some performance issues and we will like to test the 3.1 version. The rpm -i *rpm does not work, since it is also looking for libgnome inside it. We are trying to install the system in a CenOS 5.1. Any ideas are welcome?

• Where is the SQL Azure Development Environment

  - by BuckWoody

  Recently I posted an entry explaining that you can develop in Windows Azure without having to connect to the main service on the Internet, using the Software Development Kit (SDK) which installs two emulators - one for compute and the other for storage. That brought up the question of the same kind of thing for SQL Azure. The short answer is that there isn’t one. While we’ll make the development experience for all versions of SQL Server, including SQL Azure more easy to write against, you can simply treat it as another edition of SQL Server. For instance, many of us use the SQL Server Developer Edition - which in versions up to 2008 is actually the Enterprise Edition - to develop our code. We might write that code against all kinds of environments, from SQL Express through Enterprise Edition. We know which features work on a certain edition, what T-SQL it supports and so on, and develop accordingly. We then test on the actual platform to ensure the code runs as expected. You can simply fold SQL Azure into that same development process. When you’re ready to deploy, if you’re using SQL Server Management Studio 2008 R2 or higher, you can script out the database when you’re done as a SQL Azure script (with change notifications where needed) by selecting the right “Engine Type” on the scripting panel: (Thanks to David Robinson for pointing this out and my co-worker Rick Shahid for the screen-shot - saved me firing up a VM this morning!) Will all this change? Will SSMS, “Data Dude” and other tools change to include SQL Azure? Well, I don’t have a specific roadmap for those tools, but we’re making big investments on Windows Azure and SQL Azure, so I can say that as time goes on, it will get easier. For now, make sure you know what features are and are not included in SQL Azure, and what T-SQL is supported. Here are a couple of references to help: General Guidelines and Limitations: http://msdn.microsoft.com/en-us/library/ee336245.aspx Transact-SQL Supported by SQL Azure: http://msdn.microsoft.com/en-us/library/ee336250.aspx SQL Azure Learning Plan: http://blogs.msdn.com/b/buckwoody/archive/2010/12/13/windows-azure-learning-plan-sql-azure.aspx

• Libgdx detect when player is outside of screen

  - by Rockyy

  Im trying to learn libGDX (coming from XNA/MonoDevelop), and I'm making a super simple test game to get to know it better. I was wondering how to detect if the player sprite is outside of the screen and make it so it is impossible to go outside of the screen edges. In XNA you could do something like this: // Prevent player from moving off the left edge of the screen if (player.Position.X < 0) player.Position = new Vector2(0, player.Position.Y); How is this achieved in libgdx? I think it's the Stage that handles the 2D viewport in libgdx? This is my code so far: private Texture texture; private SpriteBatch batch; private Sprite sprite; @Override public void create () { float w = Gdx.graphics.getWidth(); float h = Gdx.graphics.getHeight(); batch = new SpriteBatch(); texture = new Texture(Gdx.files.internal("player.png")); sprite = new Sprite(texture); sprite.setPosition(w/2 -sprite.getWidth()/2, h/2 - sprite.getHeight()/2); } @Override public void render () { Gdx.gl.glClearColor(1, 1, 1, 1); Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); if(Gdx.input.isKeyPressed(Input.Keys.LEFT)){ if(Gdx.input.isKeyPressed(Input.Keys.CONTROL_LEFT)) sprite.translateX(-1f); else sprite.translateX(-10.0f); } if(Gdx.input.isKeyPressed(Input.Keys.RIGHT)){ if(Gdx.input.isKeyPressed(Input.Keys.CONTROL_LEFT)) sprite.translateX(1f); else sprite.translateX(10f); } batch.begin(); sprite.draw(batch); batch.end(); }

• How to make Excel's "Auto Fit Row Height" feature actually auto fit the row height?

  - by DanM

  For every generation of Excel I can remember (including 2010, which I'm using now), Excel's "Auto Size Row" features sometimes fails to actually auto size a row when the cell contains wrapped text. When it works properly, all the text is revealed and there is no additional space below the last line of text. When it fails, it adds extra space below the text. To make matters worse, what you see is not always what you get, i.e., text that appeared okay on screen gets cut off when it's printed. You also get different sizing depending on whether you are zoomed in/out or at actual size. Simple test case: Why is there a one-line gap after the text in cell A1 but in A2? (I double-checked that I applied Auto Fit Row Height to both rows. Zoom level is 100%.) Is there any known remedy for this without resorting to manually adjusting the row heights (which is not practical for more than a handful of rows)?

• GRUB-2 Bootloader fails to load for lack of floppy drive. Ubuntu 10.4 & Windows XP

  - by kammer

  2010.07.21 while trying to install Ubuntu 10.4 Hello all, I've been trying to install Ubuntu 10.04 on my Dell workstation and am unable to get the Grub-2 bootloader to load properly. It seems to be failing for lack of a floppy drive on the system resulting in an error message that reads : error: fd0 cannot get C/H/S values. I've gone through the Grub-2 page at https://help.ubuntu.com/community/Grub2 to no avail and other sources having similar problems have likewise turned up no solutions. I would certainly appreciate any insight, here's the background: A while back I was trying to install a different version of Linux and had the same problems, then had to set the project aside for a bit. I don't think this has anything to do with Linux or Ubuntu per se, but rather Grub. The system is an old (4-5 years) Dell workstation that has one drive (128 GB) set up for Windows XP and a second new drive (500GB) which I installed for Linux. There is a DVD/CD drive and the system contains no floppy drive at all. In one attempt to get this working I tried modifying the BIOS to indicate there was a floppy drive - this created a failure earlier in the chain with the BIOS failing to load properly, not unexpected, just a shot in the dark at that point.

• Limiting Sybase ASE 15 CPU usage on VM

  - by reiniero

  I've set up a single CPU Sybase ASE 15.7 test/hobby/experimentation system on a Debian Squeeze x64 KVM VM. I notice the CPU load goes to 100% and stays there. Definitely not a Sybase guru, only interested to see if some programs I'm running work on the database. Looking at Sybase docs it seems ASE detects the machine is idle and then takes over all processing just waiting for a connection (and if needed, doing some housekeeping apparently). Normally that would be fine but as it is running in a VM it's taking away processor resources other VMs could use - and the increased fan noise of the PC near my desk annoy me. I've tried to remedy this: set the "runnable process search count" parameter from DEFAULT (2000 IRC) to 3 in /opt/sybase/ASE-15_0/SYBASE.cfg from http://sybase.reygrobellet.com/tutorials/install_sybase_vb/standalone04_configure_oralin11#TOC-Configure-kernel I added this to my /etc/init.d/sybase startup script: echo 0 /proc/sys/kernel/randomize_va_space (though I don't think it'll make much difference) How can I tell Sybase to "behave" and not hog the processor - I don't mind reduced performance.

• how to print labels from UPS printer on UPS website

  - by paynes_bay

  I have several computers, in my office, that have UPS printers attached to them. On most of these computers if you go to ups.com, login, and print a shipping label out, it prints out just fine. The website somehow selects the appropriate printer and prints to it. It doesn't present a prompt, asking you to select the printer, the number of pages, etc - it just prints it. Only problem: there's one computer on which it's not doing this and I don't know why. I can see the printer in Printers and Faxes and can print out test pages from the Properties tab, so the printer clearly works - it just isn't printing out from UPS's website. Any ideas?

• Apache VERY high page load time

  - by Aaron Waller

  My Drupal 6 site has been running smoothly for years but recently has experienced intermittent periods of extreme slowness (10-60 sec page loads). Several hours of slowness followed by hours of normal (4-6 sec) page loads. The page always loads with no error, just sometimes takes forever. My setup: Windows Server 2003 Apache/2.2.15 (Win32) Jrun/4.0 PHP 5 MySql 5.1 Drupal 6 Cold fusion 9 Vmware virtual environment DMZ behind a corporate firewall Traffic: 1-3 hits/sec avg Troubleshooting No applicable errors in apache error log No errors in drupal event log Drupal devel module shows 242 queries in 366.23 milliseconds,page execution time 2069.62 ms. (So it looks like queries and php scripts are not the problem) NO unusually high CPU, memory, or disk IO Cold fusion apps, and other static pages outside of drupal also load slow webpagetest.org test shows very high time-to-first-byte The problem seems to be with Apache responding to requests, but previously I've only seen this behavior under 100% cpu load. Judging solely by resource monitoring, it looks as though very little is going on. Here is the kicker - roughly half of the site's access comes from our LAN, but if I disable the firewall rule and block access from outside of our network, internal (LAN) access (1000+ devices) is speedy. But as soon as outside access is restored the site is crippled. Apache config? Crawlers/bots? Attackers? I'm at the end of my rope, where should I be looking to determine where the problem lies?

• Setting up Ubuntu Server on Amazon EC2 for hosting multiple domains with wildcard subdomains

  - by Ashish Kumar

  I'm trying to set up multiple domains on my Amazon EC2 micro instance running Ubuntu Server 12.04. I installed Apache correctly and set up virtual hosts but having problems with wildcard subdomains. This is what my httpd.conf file looks like NameVirtualHost *:80 <VirtualHost *:80> UseCanonicalName Off VirtualDocumentRoot /home/username/domains/%0/html/ </VirtualHost> My DNS records (on Amazon Route 53) are: domain.tld A 1.2.3.4 *.domain.tld A 1.2.3.4 If i create a test.domain.tld directory with the html subdirectory, it works fine. But what I want to do is to redirect *.domain.tld to domain.tld in case there is no directory for the sub-domain accessed. I would also like www.domain.tld to redirect to domain.tld. The system should also work if I decide to host another website, example.com, on the server. I tried Googling a lot but without any luck. Suggestions?

• Trace flags - TF 1117

  - by Damian

  I had a session about trace flags this year on the SQL Day 2014 conference that was held in Wroclaw at the end of April. The session topic is important to most of DBA's and the reason I did it was that I sometimes forget about various trace flags :). So I decided to prepare a presentation but I think it is a good idea to write posts about trace flags, too. Let's start then - today I will describe the TF 1117. I assume that we all know how to setup a TF using starting parameters or registry or in the session or on the query level. I will always write if a trace flag is local or global to make sure we know how to use it. Why do we need this trace flag? Let’s create a test database first. This is quite ordinary database as it has two data files (4 MB each) and a log file that has 1MB. The data files are able to expand by 1 MB and the log file grows by 10%: USE [master] GO CREATE DATABASE [TF1117]  ON  PRIMARY ( NAME = N'TF1117',      FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL12.SQL2014\MSSQL\DATA\TF1117.mdf' ,      SIZE = 4096KB ,      MAXSIZE = UNLIMITED,      FILEGROWTH = 1024KB ), ( NAME = N'TF1117_1',      FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL12.SQL2014\MSSQL\DATA\TF1117_1.ndf' ,      SIZE = 4096KB ,      MAXSIZE = UNLIMITED,      FILEGROWTH = 1024KB )  LOG ON ( NAME = N'TF1117_log',      FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL12.SQL2014\MSSQL\DATA\TF1117_log.ldf' ,      SIZE = 1024KB ,      MAXSIZE = 2048GB ,      FILEGROWTH = 10% ) GO Without the TF 1117 turned on the data files don’t grow all up at once. When a first file is full the SQL Server expands it but the other file is not expanded until is full. Why is that so important? The SQL Server proportional fill algorithm will direct new extent allocations to the file with the most available space so new extents will be written to the file that was just expanded. When the TF 1117 is enabled it will cause all files to auto grow by their specified increment. That means all files will have the same percent of free space so we still have the benefit of evenly distributed IO. The TF 1117 is global flag so it affects all databases on the instance. Of course if a filegroup contains only one file the TF does not have any effect on it. Now let’s do a simple test. First let’s create a table in which every row will fit to a single page: The table definition is pretty simple as it has two integer columns and one character column of fixed size 8000 bytes: create table TF1117Tab (      col1 int,      col2 int,      col3 char (8000) ) go Now I load some data to the table to make sure that one of the data file must grow: declare @i int select @i = 1 while (@i < 800) begin       insert into TF1117Tab  values (@i, @i+1000, 'hello')        select @i= @i + 1 end I can check the actual file size in the sys.database_files DMV: SELECT name, (size*8)/1024 'Size in MB' FROM sys.database_files  GO   As you can see only the first data file was  expanded and the other has still the initial size:   name                  Size in MB --------------------- ----------- TF1117                5 TF1117_log            1 TF1117_1              4 There is also other methods of looking at the events of file autogrows. One possibility is to create an Extended Events session and the other is to look into the default trace file:     DECLARE @path NVARCHAR(260); SELECT    @path = REVERSE(SUBSTRING(REVERSE([path]),          CHARINDEX('\', REVERSE([path])), 260)) + N'log.trc' FROM    sys.traces WHERE   is_default = 1; SELECT    DatabaseName,                 [FileName],                 SPID,                 Duration,                 StartTime,                 EndTime,                 FileType =                         CASE EventClass                                     WHEN 92 THEN 'Data'                                    WHEN 93 THEN 'Log'             END FROM sys.fn_trace_gettable(@path, DEFAULT) WHERE   EventClass IN (92,93) AND StartTime >'2014-07-12' AND DatabaseName = N'TF1117' ORDER BY   StartTime DESC;   After running the query I can see the file was expanded and how long did the process take which might be useful from the performance perspective.    Now it’s time to turn on the flag 1117. DBCC TRACEON(1117)   I dropped the database and recreated it once again. Then I ran the queries and observed the results. After loading the records I see that both files were evenly expanded: name                  Size in MB --------------------- ----------- TF1117                5 TF1117_log            1 TF1117_1              5 I found also information in the default trace. The query returned three rows. The last one is connected to my first experiment when the TF was turned off.  The two rows shows that first file was expanded by 1MB and right after that operation the second file was expanded, too. This is what is this TF all about J

• Change smtp name

  - by Misterb

  Hello, My question is probably very easy to answer but I have been struggling with this the whole day. Actually, I would like to change my smtp.mail name and account that is shown as sending the emails in the header. I changed the "From" but it shows only in the "visible" part of the email and there are values that are different in the header. In this example : Received-SPF: pass (google.com: domain of [email protected] designates 67.221.174.127 as permitted sender) client-ip=67.221.174.127; Authentication-Results: mx.google.com; spf=pass (google.com: domain of [email protected] designates 67.221.174.127 as permitted sender) [email protected]; dkim=pass (test mode) [email protected] [email protected] account=bounce Thank you in advance!

• PHP script timed out, or otherwise killed on Apache under CentOS (shared host)

  - by MarkS

  When trying to run a PHP script (CentOS, Apache, PHP 5.2), that may take a long time, it is apparently killed after 45 minutes. PHP script is invoked from a web browser, and in certain situations, it will do a lot of work processing a POP3 mailbox and sending emails as part of an automated monitoring system. Running the PHP script from the command line might be a better option, but I want to understand what is going on so far. I ran a test script, and it appeared to finally give an internal server error (500?) after 45 minutes. Where is this limit set and what is killing the script, if that is what is happening? It's running on a shared host on Hostgator.com.

• List SQL Server Instances using the Registry

  - by BuckWoody

  I read this interesting article on using PowerShell and the registry, and thought I would modify his information a bit to list the SQL Server Instances on a box. The interesting thing about listing instances this was is that you can touch remote machines, find the instances when they are off and so on. Anyway, here’s the scriptlet I used to find the Instances on my system: $MachineName = '.' $reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $MachineName) $regKey= $reg.OpenSubKey("SOFTWARE\\Microsoft\\Microsoft SQL Server\\Instance Names\\SQL" ) $regkey.GetValueNames() You can read more of his article to find out the reason for the remote registry call and so forth – there are also security implications here for being able to read the registry. Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems. Always check the script on a test system or Virtual Machine, not a production system. Yes, there are always multiple ways to do things, and this script may not work in every situation, for everything. It’s just a script, people. All scripts on this site are performed by a professional stunt driver on a closed course. Your mileage may vary. Void where prohibited. Offer good for a limited time only. Keep out of reach of small children. Do not operate heavy machinery while using this script. If you experience blurry vision, indigestion or diarrhea during the operation of this script, see a physician immediately.
