  • How to open a page in Chrome from the command line, in a new tab or an existing tab as appropriate?

    - by MattH
    I'm looking for a way to open a given page in Google Chrome from the command line, with the following behaviour: If the given page is already open in a tab, navigate to that tab If the given page is not already open in a tab, open the page in a new tab and show that tab Currently when I open a URL from the command line (e.g. using "open http://godzillahaiku.tumblr.com" on Mac OS X), Chrome will always open the URL in a new tab. I end up with lots of duplicate tabs as a result, which is a minor annoyance. I'm looking for a solution that works on Mac OS X, but a non-OS specific solution would be preferable. I'd consider writing a Chrome extension for this if there's no existing solution.

  • Obscure SPUtility.SendMail Behavior When Manually Passing in Mail Headers

    - by Damon
    There are two ways to send mail in SharePoint: you can either use the mail components from the System.Net namespace, or you can send email using SharePoint's SPUtility.SendMail method.  One of the benefits of the SPUtility.SendMail method is that it uses the mail configuration from SharePoint, so you can manage settings in Central Administration instead of having to go through and modify your web.config file.  SPUtility.SendMail can get the job done, but it's defiantly not as developer friendly as the components from the System.Net namespace.  If you want to CC someone on an email, for example, you do NOT have a nice CC parameter - you have to manually add the CC mail header and pass it into the SPUtility.SendMail method.  I had to do this the other day, and ran into a really obscure issue. If you do NOT pass the headers into the method then SharePoint sends the email using the From Address configured in the Outgoing Mail settings in Central Admin.  If you pass headers into the method, but do not include the from header, then SharePoint sends the mail using the email address of the current user. This can be an issue if your mail server is setup to reject an email from an invalid email address or an email address that is not on your domain.  The way to fix this issue is to always pass in the from header.  If you want to use the configured From address, then you can do the following: SPWebApplication webApp = SPWebApplication.Lookup(new Uri(SPContext.Current.Site.Url)); StringDictionary headers = new StringDictionary(); headers.Add("from", webApp.OutboundMailSenderAddress);

  • What does this WinImage Error Mean?

    - by Kryten
    Hi, I am using WinImage (version 8.0) on Windows XP SP3 to create a VHD File from my Hard Drive, however, everytime I try to, everytime it says: "I/O error in reading data on position 000000007cd40000:00010000. Error 23: Data Error (cyclic redundancy check)." with the options "Abort", "Retry", "Skip" & "Skip All". Everytime I try "Retry" the message comes, if I click skip another message comes up (same as above, except the data position). I have run "CHKDSK /F /R" several times, but the error always appears. What is wrong? Can I safely skip the Errors? Is there anything I can do to fix the error?

  • How to use launchd to ensure an application is running?

    - by zneak
    Hello guys, I use Quicksilver, which is a nifty program that really speeds up my work. I've set it to launch when I log in. However, since Snow Leopard, it's become a bit less stable, and once in a while, it crashes. And obviously, it won't restart by itself. I'm pretty sure I can use launchd to ensure it's always running when I'm logged in. Is there a good guide/example of how to make sure a process restarts when it's killed/terminated/crashed with it?

  • Web Hosting Checklist

    - by Chris
    Hello, I am a web developer that is starting to look into hosting his own website. I would like to showcase my programming skills (PHP, MySQl, C#, Wordpress). My knowledge of languages I am OK with but the actually hosting site is where my knowledge starts to get a little shaky. I know the basics (bandwidth, sub-domains, re-write rules) but I would love your input, to help me formulate a check list of certain web-hosting services that I should be on the look-out for. Also I was wondering if there were any reliable hosting providers who give you the option to host both c# code-behinds and PHP code. As I would like to have two versions of my site, one in C# and one in PHP the hope is that if I need to look for another job this website will help me show possible employers my server side knowledge. I hope this is enough info, I did some researching online but found a bunch of unless articles and I've always have had luck on the StackExchange sites. So hopefully you, can help me. Thanks alot.

  • Importing tab delimited file into array in Visual Basic 2013 [migrated]

    - by JaceG
    I am needing to import a tab delimited text file that has 11 columns and an unknown number of rows (always minimum 3 rows). I would like to import this text file as an array and be able to call data from it as needed, throughout my project. And then, to make things more difficult, I need to replace items in the array, and even add more rows to it as the project goes on (all at runtime). Hopefully someone can suggest code corrections or useful methods. I'm hoping to use something like the array style sMyStrings(3,2), which I believe would be the easiest way to control my data. Any help is gladly appreciated, and worthy of a slab of beer. Here's the coding I have so far: Imports System.IO Imports Microsoft.VisualBasic.FileIO Public Class Main Dim strReadLine As String Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim sReader As IO.StreamReader = Nothing Dim sRawString As String = Nothing Dim sMyStrings() As String = Nothing Dim intCount As Integer = -1 Dim intFullLoop As Integer = 0 If IO.File.Exists("C:\MyProject\Hardware.txt") Then ' Make sure the file exists sReader = New IO.StreamReader("C:\MyProject\Hardware.txt") Else MsgBox("File doesn't exist.", MsgBoxStyle.Critical, "Error") End End If Do While sReader.Peek >= 0 ' Make sure you can read beyond the current position sRawString = sReader.ReadLine() ' Read the current line sMyStrings = sRawString.Split(New Char() {Chr(9)}) ' Separate values and store in a string array For Each s As String In sMyStrings ' Loop through the string array intCount = intCount + 1 ' Increment If TextBox1.Text <> "" Then TextBox1.Text = TextBox1.Text & vbCrLf ' Add line feed TextBox1.Text = TextBox1.Text & s ' Add line to debug textbox If intFullLoop > 14 And intCount > -1 And CBool((intCount - 0) / 11 Mod 0) Then cmbSelectHinge.Items.Add(sMyStrings(intCount)) End If Next intCount = -1 intFullLoop = intFullLoop + 1 Loop End Sub

  • Tree Surgeon 2.0 - The future on the T4 Express

    - by Malcolm Anderson
    If you've never been a fan of TreeSurgeon (http://treesurgeon.codeplex.com/) then skip this post.However, if have been there have been some interesting developments over the last couple of years.The biggest one is T4Recently Bill Simser wrote a detailed post about the potential future of tree surgeon, called "Tree Surgeon - Alive and Kicking or Dead and Buried" He raised the question:Times have changed. Since that last release in 2008 so much has changed for .NET developers. The question is, today is the project still viable? Do we still need a tool to generate a project tree given that we have things like scaffolding systems, NuGet, and T4 templates. Or should we just give the project its rightful and respectful send off as its had a good life and has outlived its usefulness.For myself, the answer is, keep it.I've spent the last couple of years doing agile engineering coaching and architecture and from my experience, I can tell you, there are a lot of shops out there that would benefit from having Tree Surgeon as a viable product.  Many would benefit simply from having the software engineering information that is embedded in the tree surgeon site be floating around their conversation.Little things like, keep all of your software needed to run the build, with the build in the version control system.Have your developers and the build system using the same build.Have a one-touch buildSeparate your code from your interfacePut unit tests in first, not lastI've seen companies with great developers suffer from the problems that naturally come from builds taking 3 and 4 hours to run.  It takes work to get that build down to 10 minutes, but the benefits are always worth it.  Tree Surgeon gives you a leg up, by starting you off with a project that you can drop into your Continuous Integration system, right out of the box.Well, it used to be right out of the box.  Today, you have to play with the project to make it work for you, but even with the issues (it hasn't been updated since 2008) it still gives you a framework, with logical separations that you can build from.If you have used Tree Surgeon in the past, take a few minutes and drop a comment about what difference it made in your development style, and what you are doing differently today because of it.

  • Self-hosted browser-based remote desktop script?

    - by rlsaj
    I need a self-hosted browser based remote desktop script that will connect me from any PC to my work PC. I need to either host this script within my own dedicated hosting or on my work PC. The PC that I need to remote into is always the one PC (Win7) and the IP never changes, and I have access to the Router/Firewall within. I have tried many remote desktop services and applications - LogMeIn, Team Viewer, (Ultra/Tight) VNC, GoToMyPC and iTeleport Connect and even Windows Remote Desktop - and the web services (or ports) are blocked at whatever free wi-fi/hotel/coffee shop I am at. Note that I will need to be able to access this from any PC, so I won't be able to install any applications (or use any portable software) - hence my thinking that it will need to be browser based on a standard (not blocked) port. If I can set up a web based remote desktop application - really a homebrew LogMeIn - then I should solve my problem. What is the best option here?

    I Have a macro containing a line that will change the formula of a cell using R1C1 formula type. The formula is: ActiveCell.FormulaR1C1 = _ "=IF(R[0]C[-2]=0,"",(R[0]C[-20]-R[0]C[-16]))" When ever I attempt to run the macro it always comes up with a dialog box saying Run-time error '1004': Application-defined or object-defined error. And when you click debug it highlights those 2 lines in the macro. And I can't figure out how to fix it. Can anyone help?

  • HP-UX -> Linux incremental remote backup

    - by stack_zen
    Hi. I've the need to setup a differential backup process from a range of remote HP-UXes to a central RHEL5 server. I'd happily go with rsync, problem is, stock HP-UX 11.11 has no built-in rsync and I don't have permissions to install any software on the remote stock HP-UXes. How should I approach this? HP-UX provides: fbackup (HP-UX exclusive) cpio (available in RHEL5, allows backing up only the files which changed, but always grabs the totality of the file) ssh remote_user@remote_host 'find /u01/engine/logs/ -type f -name "*.log" | cpio -o | gzip -' | cpio gunzip - | -idmv Those solutions don't really answer my incremental (bandwidth efficiency) problem do they?

  • Microsoft Outlook tips and tricks for improving user experience?

    - by Roee Adler
    I'm one of those heavy Microsoft Outlook users, currently working on the 2007 version. God knows this tool is heavy and may impose problems. I wondered what the Super User crowd has to suggest in order to improve the usage experience. Several suggestions of my own: Always work in cached mode (Tools--Account Settings--Change--Use Cached Exchange Mode) Use Outlook's local archiving capabilities Use Outlook's RSS reader - it's simple and allows offline access to your feeds If you have e-mail subscriptions to magazines, blogs, etc. - create a subdirectory to keep them, and a rule to automatically move them there when they arrive (one rule per subscription, based on the sender e-mail.) You can also share suggestions that require configuration of Exchange Server, for those of us who can make bring them to their IT managers. What are your suggestions? PS: "Use Gmail" is not an accepted answer, some of us don't control what email system we use...

  • Is it safer to use the same IV all times data are encrypted, or use a dynamic IV that is sent together the encrypted text? [closed]

    - by kiamlaluno
    When encrypting data that is then send to a server, is it better to always use the same IV, which is already known from the receiving server, or use a dynamic IV that is then sent to the receiving server? I am referring to the case the remote server receives data from another server, or from a client application, and executes operations on a database table, in the table row identified by the received data. Which of the following PHP snippets is preferable? $iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td), MCRYPT_RAND); $ks = mcrypt_enc_get_key_size($td); $key = substr(md5('very secret key'), 0, $ks); mcrypt_generic_init($td, $key, $iv); $encrypted = mcrypt_generic($td, 'This is very important data'); send_encripted_data(combine_iv_encrypted_text($iv, $encrypted)); $ks = mcrypt_enc_get_key_size($td); $key = substr(md5('very secret key'), 0, $ks); mcrypt_generic_init($td, $key, $iv); send_encripted_data(mcrypt_generic($td, 'This is very important data')); In which way is one of the snippets more vulnerable than the other one?

  • Experience with MQ File Transfer Edition?

    - by mfinni
    We've got several processes that move files across servers - SFTP, FTP, SCP; Windows, Linux, AIX; there is a workflow component (usually require a control file with filenames and hash values to move a batch of related files). The action is often initiated on our servers to get the files, so we need to make sure they're done being written. We have some homegrown scripts to do this, but they don't always work properly, and troubleshooting, maintenance, and log review is not easy this way. There's a lot of servers, and our scripts don't have central logging or a dashboard/console/etc. We're looking into commercial products to do this. Has anyone used MQ File Transfer Edition? Another team in our company is using Aspera, does anyone have any thoughts on that, or other favored products? I have no idea what our budget is for this, yet. Just trying to get a handle on the product space from the perspective of other admins.

  • Automatic server redirect that passes through as the referring site

    - by nsearle
    Hey All, As always, I would like to thank all of your help and assistance in advance. I am looking for a way to automatically redirect a user to a site and maintain the redirect site as the referral site. Let me explain the process and what is needed in a step by step format. User clicks on a desired link in an email User is navigated to testdomain.com User is automatically redirected to test.com/landing test.com sees testdomain.com as the referral site Data is gathered via Google Analytics I am unsure as if this PHP code will take care of it, or not - header("Location: http://google.com", true, 303); I could test and that is most likely what I am going to do. But I would like to understand a little more as to WHY this would or WHY this wouldn't work.

  • Can I change the system's "Browse for Folder" dialog globally?

    - by Chris Phillips
    As far as I know, everyone hates the "Browse for Folder" dialog: This dialog is always too small, rarely remembers locations well, and worst of all: forces you to navigate your entire computer using a tedious tree structure. Now, to be fair, some of the problems are likely to do with how apps are invoking the control -- not setting a size or a default directory, etc. But the problem about the tedious tree control remains. Is there any way to customize your Windows installation to use a different control? Preferably an app/installer that does it for you safely, but dropping in a compatible DLL or similar technique would be okay too. Or are we stuck with this terrible control forever?

  • KDE: How can I select audio output device for mplayer?

    - by grimripper
    I recently installed Kubuntu 13.10 64-bit, and I'm having a problem with selecting audio output device. In Phonon, when I select audio device preference order and press Apply, Amarok and Dragon will immediately switch to the preferred device. VLC and SMplayer are not affected. VLC has its own setting for selecting the output device, but SMplayer remains a problem. It always plays audio on internal audio, and I can't change output to HDMI. How can I select HDMI for SMplayer's audio output device? I don't know if it matters, but when I select HDMI audio in Phonon and click Test, the test sound plays on the internal audio output as well. In the hardware settings tab, the front left and front right test buttons play audio on HDMI. Also, volume up/down buttons affect HDMI volume when SMplayer is focused. This would make sense if I could get SMplayer to play audio over HDMI, but it would be better if the volume keys affected SMplayer's own volume, or the "mplayer2: audio stream" which appears in volume control while mplayer is playing. EDIT: I've recompiled mplayer with alsa support, and can now select the audio output device from SMplayer's settings. Didn't affect the issue with Phonon of course, but it's a suitable workaround.

  • Cannot boot from a hard drive

    - by Martin Melka
    I have a problem booting from a hdd. I used to have it as my main drive before I bought an SSD, so I had been able to boot from it. But for some reason, now, half a year later, I can't get it to work. I completely erased it, deleting data and partitioning (using EASEUS Partition Master), then I installed Kubuntu (without changing anything in the installer), but it simply won't boot up. It always boots the drive with Windows and when I unplug this drive, it only gives me an error "PXE-E61: Media test failure, check cable", I guess it's trying to boot from LAN. I tried installing the system on a freshly deleted drive, without any other drives plugged in the pc, but the problems persist. This is how the drives look now (first one has Windows 7 installed, the second one Kubuntu): I am lost. I mean, after doing a fresh wipe and a clean install without altering anything, it should work. But it doesn't. What can be wrong here? Thanks

  • Tip: Keeping the ADF Mobile PDF Guide up to date

    - by Chris Muir
    This is a little tip for customers using Oracle's ADF Mobile. If you're like me, it's possible you don't rely on the online HTML version of the Mobile Developer's Guide for ADF, but rather download a PDF version of the file to use locally (look to the "PDF" link to the top right of the guide).  For me the convenience of the PDF is it's faster, I can search the whole document easily, I can split read the document across two pages on my home monitor, if I lose my internet connection the document is still available, and it's easy to read on my iPad (especially on long haul flights to the US across the Pacific where there is no internet connection!). The trigger point for me to download the Oracle PDF documentation has always been on a new point release of JDeveloper.  However in the case of ADF Mobile, as an extension to JDeveloper it is releasing at a much faster and independent schedule to JDeveloper and this includes updates to the documentation. As such the 11.1.2.4.0 ADF Mobile PDF guide you have locally might be out of date and you should take the opportunity to download the latest version.  This is also particularly important for ADF Mobile as not only are many new features being added for each release and included in the new documentation, but the guide is under rapid improvement to clarify much of what has been written to date.  Our documentation teams are super responsive to suggestions on how to improve the guides and this often shows per point release. How do you tell you've the latest guide? Look to the document part number which right now is "E24475-03".  This is a unique ID per release for the document, the first part being the document number, and the part after the dash the revision number.  If the website document number has a higher revision number, time to download a new up to date PDF. One last thing to share, you can follow the ADF Mobile guide document manager Brian Duffield on Twitter to keep abreast of updates. Image courtesy of Stuart Miles / FreeDigitalPhotos.net

  • A Star Path finding endless loop

    - by PoeHaH
    I have implemented A* algorithm. Sometimes it works, sometimes it doesn't, and it goes through an endless loop. After days of debugging and googling, I hope you can come to the rescue. This is my code: The algorythm: public ArrayList<Coordinate> findClosestPathTo(Coordinate start, Coordinate goal) { ArrayList<Coordinate> closed = new ArrayList<Coordinate>(); ArrayList<Coordinate> open = new ArrayList<Coordinate>(); ArrayList<Coordinate> travelpath = new ArrayList<Coordinate>(); open.add(start); while(open.size()>0) { Coordinate current = searchCoordinateWithLowestF(open); if(current.equals(goal)) { return travelpath; } travelpath.add(current); open.remove(current); closed.add(current); ArrayList<Coordinate> neighbors = current.calculateCoordAdjacencies(true, rowbound, colbound); for(Coordinate n:neighbors) { if(closed.contains(n) || map.isWalkeable(n)) { continue; } int gScore = current.getGvalue() + 1; boolean gScoreIsBest = false; if(!open.contains(n)) { gScoreIsBest = true; n.setHvalue(manhattanHeuristic(n,goal)); open.add(n); } else { if(gScore<n.getGvalue()) { gScoreIsBest = true; } } if(gScoreIsBest) { n.setGvalue(gScore); n.setFvalue(n.getGvalue()+n.getHvalue()); } } } return null; } What I have found out is that it always fails whenever there's an obstacle in the path. If I'm running it on 'open terrain', it seems to work. It seems to be affected by this part: || map.isWalkeable(n) Though, the isWalkeable function seems to work fine. If additional code is needed, I will provide it. Your help is greatly appreciated, Thanks :)

  • Giving a scanner-printer-combo a zoom function when copying ?

    - by ldigas
    You know how everytime you go to a photocopying shop, photocopiers always have a neat zoom function (it can take whatever you give it, and zoom it in/out, so your copy comes out smaller or larger). I got one of those neat 3-in-one printer machines. It has a copy button on it, but it also has some software that comes with it (Epson SX115 to be exact is the model). Apart from going into some photo manipulation application, is there some way (software) to give it that feature. So, in short, I need something that can scan a page, scale it to let's say, a quarter of its size, and then print it out ? Anyone knows of anything like that ?

  • Panic Transmit file upload

    - by 1ndivisible
    I've ditched Coda and bought Transmit. I'm a little confused by the file uploading. I have exactly the same folder structure remotely and locally, but if I right-click a file and choose Upload "SomeFileName.html" The file is always uploaded into the root of the remote site, even if the file is in a folder. If I choose to upload a file at assets/images/some_image.png I would expect it to be uploaded to the same folder on the remote server, not the root. Coda dealt with this perfectly and also told me what files had been modified and needed uploading. Transmit doesn't seem to do either of these things. So my questions are: How can I upload a file to the same path on the remote server without having to drag and drop Is there any way to have Transmit mark edited files or upload only edited files. [There is no tag for Transmit so if someone with more rep could make and add one that would be grand]

  • XNA hlsl tex2D() only reads 3 channels from normal maps and specular maps

    - by cubrman
    Our engine uses deferred rendering and at the main draw phase gathers plenty of data from the objects it draws. In order to save on tex2D calls, we packed our objects' specular maps with all sorts of data, so three out of four channels are already taken. To make it clear: I am talking about the assets that come with the models and are stored in their material's Specular Level channel, not about the RenderTarget. So now I need another information to be stored in the alpha channel, but I cannot make the shader to read it properly! Nomatter what I write into alpha it ends up being 1 (255)! I tried: saving the textures in PNG/TGA formats. turning off pre-computed alpha in model's properties. Out of every texture available to me (we use Diffuse map, Normal Map and Specular Map) I was only able to read alpha successfully from the Diffuse Map! Here is how I add specular and normal maps to my model's material in the content processor: if (geometry.Material.Textures.ContainsKey(normalMapKey)) { ExternalReference<TextureContent> texRef = geometry.Material.Textures[normalMapKey]; geometry.Material.Textures.Remove("NormalMap"); geometry.Material.Textures.Add("NormalMap", texRef); } ... foreach (KeyValuePair<String, ExternalReference<TextureContent>> texture in material.Textures) { if ((texture.Key == "Texture") || (texture.Key == "NormalMap") || (texture.Key == "SpecularMap")) mat.Textures.Add(texture.Key, texture.Value); } In the shader I obviously use: float4 data = tex2D(specularMapSampler, TexCoords); so data.a is always 1 in my case, could you suggest a reason?
