  • git tagging comments - best practices

    - by Evan
    I've adopted a tagging system of x.x.x.x, and this works fine. However, you also need to leave a comment with your git tag. I've been using descriptions such as "fixes bug Y" or "feature X", but is this the best sort of comment to be leaving? Particularly, what if a tag encompasses several fixes, it seems not to make sense to have a very long tag comment. Does this mean that I should be creating a tag for every bug fix or feature, or should the tag comments be reflective of something else? I have a few ideas that may be good, but I'd love some advice from seasoned git tagging veterans :) For those who prefer specific examples: 1.0.0.0 - initial release 1.0.0.1 - bug fix for issue X 1.0.0.2 - (what if this is a bug fix for multiple issues, the comment would be too long, no?) Another example, in this example, the comments are more or less the same as the tags, it seems redundant. Is there something else we could be describing? https://github.com/osCommerce/oscommerce2/tags

  • How to get more detailed reason for Thunderbird crashing?

    - by Nick
    I have a computer (10.04) that was previously running Thunderbird 12.0.1 just fine (installed via apt-get via official PPA). I don't know what happened at the time the problem started since this is a multi-user computer and I was not here. However, every time we try to launch TB, we immediately get a dialog that says: We're Sorry Thunderbird had a problem and crashed. Things I've tried: Running thunderbird from a terminal produces no output. I tried apt-get remove thunderbird --purge and then reinstalled Deleting the user's .thunderbird folder and launching still results in a crash Attempting to run thunderbird -safe-mode still results in a crash This problem occurs for all users of Thunderbird on this computer. Is there any way to get more details on why the program is crashing? For example, the specific error that TB is encountering? I tried thunderbird -g but I'm not sure what to do with the debugger.

  • How to fix “Unable to cast COM object of type ‘Microsoft.SharePoint.Library.SPRequestInternalClass’ to interface type ‘Microsoft.SharePoint.Library.ISPRequest” using PowerGUI

    - by ybbest
    I got the error today when debugging some of my PowerShell Script in PowerGUI. The script works perfectly fine in PowerShell console. Then I had spent a couple of hours scratching my head, trying to figure out why. It turns out that the PowerShell Variables Panel causes the problem. Not quite sure why, but collapse the panel fix the problem. Problem: It throws the following exception when debugging my PowerShell Script. Analysis: It turns out that the PowerShell Variables Panel causes the problem. I assume it calls some function to grab value of some of variables which cause the problems. Solution: Collapse or Close the variables panel fix the problem

  • No Wi-Fi after system reboot

    - by ILya
    Something strange is happening... I've installed a Wi-Fi card into my Ubuntu Server 11.04 machine. To configure it I do the following: sudo vi /etc/network/interfaces add: iface wlan0 inet dhcp wpa-driver wext wpa-ssid "Sweet Home" wpa-ap-scan 1 wpa-proto WPA wpa-pairwise TKIP wpa-group TKIP wpa-key-mgmt WPA-PSK wpa-psk <A KEY> auto wlan0 then: $ sudo /etc/init.d/networking restart * Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces * Reconfiguring network interfaces... ssh stop/waiting ssh start/running, process 1522 ssh stop/waiting ssh start/running, process 1590 And my machine successfully gets an ip to my wireless adapter. But after reboot it doesn't get any ip in wireless network. To fix it I run /etc/init.d/networking restart again and all is fine again - it gets an ip. I understand that I simply should add it to my startup scripts to make it work properly, but maybe there is a better way to configure it?

  • Can't adjust screen brightness on Macbook Pro 10,1 Ubuntu 13.10

    - by ben101
    I recently installed Ubuntu on my retina Macbook Pro (following this great guide: http://cberner.com/2013/03/01/installing-ubuntu-13-04-on-macbook-pro-retina/) Everything works fine so far however the screen brightness / backlight cannot be adjusted neither by using the assigned key nor by any other means. I know, I'm not the first to address this problem, but all the suggested solutions I found so far did not work for me. I unsuccessfully tried the following: Including Option "RegistryDwords" "EnableBrightnessControl=1" in the Devices-Section of /etc/X11/xorg.conf the application xbacklight I also haven't found any file such as mbp_backlight or apple_backlight on my system which probably would be a starting point I'm using the Nvidia-driver. (BTW: With the nouveau-driver, the keys to adjust the brightness work. However, with the nouveau driver Ubuntu does not resume from suspend mode) Any suggestions what I can do? Thanks!

  • How do I get my Canon MF4410 printer to work in Ubuntu 12.04?

    - by Kevin
    I have a Canon i-sensys MF4410 laser printer. I am running a dual boot system with Windows 7 and Ubuntu 12.04. The printer works in Windows and Ubuntu sees it when I attempt to add a new printer but I cannot get it to work in Ubuntu. (It previously worked fine under Ubuntu 8.?) I have tried installing (and un-installing) the driver cque-en but, although Ubuntu sees the printer, it does not find the driver. I have even tried using the generic laser and 'text only' drivers but these do not work. If anyone can help and it requires using terminal please give detailed instructions. Thanks Kevin

    I updated Ubuntu to 13.10 last night and wifi was working fine until I went to wake up my computer this morning and no WiFi connection. I am on a iMac with Qualcomm Atheros AR93xx Wireless Network Adapter [168c:0030] (rev 01). The only solutions I have seen so far are for broadcomm WiFi drivers. There is no wifi driver in addition drivers only graphics drivers. Not sure how to fix this, Any help would be greatly appreciated. UPDATE: WiFi works after reboot but doesn't after being put to sleep nor does Ethernet connect after sleep.

  • Google Talk Plugin in GMail on MacBook 2,1

    - by jrc03c
    I'd like to use the chat section in GMail to make phone calls. I've downloaded and installed the Google Talk plugin, and it acts like it knows what it's doing. But when I try to make calls, the internal laptop mic doesn't work at all (i.e., no one on the other end can hear me). In the GMail chat settings, I've tried selecting "Default Device" for the microphone, as well as "Internal Audio Analog Stereo." No matter which setting I try, none seem to work. As I said at the top, this is only a problem in Ubuntu; it works just fine in OSX and Windows (which means that yes, my Google Voice account is properly configured). Here are my tech specs: Ubuntu 10.10 Kernel Linux 2.6.35-24-generic Gnome 2.32.0 Google Chrome 8.0.552.237 Google Talk Plugin (google-talkplugin) 1.8.0.0-1 MacBook (2,1) w/ internal microphone Any help will be greatly appreciated! Thanks!

  • Installing ubuntu on MacBook Pro 9,1

    - by pratnala
    I bought a MacBook Pro 9,1 (Mid 2012, 15inch, NOT retina). Can anyone tell me how to install Ubuntu 12.04 on it? I already have Windows installed via BootCamp. Also, where to install drivers for Ubuntu and all? This link https://help.ubuntu.com/community/MacBookPro has nothing for 9,1 so please help me. If I have to remove BootCamp and reinstall Windows manually because BootCamp doesn't allow resizing of partitions, that's fine. Please tell me how to install Precise on MBP 9,1 Thanks!

  • Ubuntu no longer prompts for root privilege (but doesn't give it either)

    - by Elad Avron
    So on 14.04 LTS I was playing around with some settings to solve another problem, and somehow managed to screw things up and now Ubuntu no longer asks for root privileges before trying to perform administrative actions. The catch is that my user does NOT have them by default, which means those actions ALL fail. I can still run "sudo " from terminal and it'll ask for my password and work fine, but any GUI that requires root just fails without asking anything. Any ideas what I did wrong and how to solve it? Thanks in advance.

  • Sharing code in LGPL and proprietary software

    - by Martin
    Hi I'm working on a piece of software that'll be released as a dll under LGPL. The software interfaces with hardware from a small company that has provided me with the needed libraries and some code to use them correctly (not only headers but its all in a separate file). As far as i know, the same code is used in their proprietary software that they don't intend to open source but they'd be fine releasing the piece of code they've given me. Now here's the question: What license could be used on the code I got from the company? I guess using GPL or LGPL would make them violate GPL when using the same code in their other software. Is MIT a good idea? Is it ok to just include a file with MIT license on it in my otherwise LGPL:ed project? Since I'm not the copyright holder, I'd have to ask the company to apply the license obviously but that shouldn't be a problem. Thanks /Martin

  • Cannot connect to google talk using empathy/pidgin after upgrading

    - by levesque
    I can't seem to be able to connect to google talk using either pidgin or empathy after upgrading to Ubuntu 10.10 (fresh install). I do not know why... empathy just writes "Connecting ..." forever and never connects. What can I do from there? Google talk's web interface works just fine for me so I doubt it is a firewall issue. EDIT: In fact sometimes it's able to connect (empathy), it just takes a LOOONG time (I'd say about 5 mins), longer than I am willing to wait. On the other hand, the web interface is able to connect in seconds.

  • Ubuntu 12.04 transmission-daemon and zfsonlinux: bad file descriptor and corrupt pieces

    - by Ivailo Karamanolev
    I'm running a Ubuntu 12.04 with zfsonlinux and transmission-daemon. The issues: sporadic Bad File Descriptor and Piece #xxx is corrupt errors. After I recheck the torrent, everything seems fine. That happens only when downloading: once it's in seeding mode. This only happens after the torrent client has been running for some time. I installed zfsonlinux from the offical stable ppa (https://launchpad.net/~zfs-native/+archive/stable). I previously tried running transmission-daemon from the Ubuntu repository, but since I've switched to building the latest transmission from source with the latest libevent (all stable) - same thing. I've seen bug reports (https://trac.transmissionbt.com/ticket/4147) for that issue, but none of them seem to have a solution. How can I fix these errors, or at least understand where they come from and what I can do to rectify the issue?

  • Sorting: TransientVO Vs Query/EO based VO

    - by Vijay Mohan
    In ADF, you can do a sorting on VO rows by invoking setSortBy("VOAttrName") API, but the tricky part is that, this API actually appends a clause to VO query at runtime and the actual sorting is performed after doing VO.executeQuery(), this goes fine for Query/EO based VO. But, how about the transient VO, wherein the rows are populated programmatically..?There is a way to it..:)you can actually specify the query mode on your transient VO, so that the sorting happens on already populated VO rows.Here are the steps to go about it..//Populate your transient VO rows.//VO.setSortBy("YourVOAttrName");//VO.setQueryMode(ViewObject.QUERY_MODE_SCAN_VIEW_ROWS);//VO.executeQuery();So, here the executeQuery() is actually the trigger which calls for VO rows sorting.QUERY_MODE_SCAN_VIEW_ROWS flag makes sure that the sorting is performed on the already populated VO cache.

  • Can&rsquo;t install Transport HUB in Exchange 2010

    - by Kelly Jones
    When building my latest SharePoint 2010 demo virtual machines, I decided to try installing Exchange 2010 as well.  Now, I’m not an Exchange admin, but I thought “how hard can this be?”  Well, a little more than I thought. Pretty early during the install, I got an error saying that it couldn’t “install Transport HUB”.  I double checked that my VM was meeting all of the requirements, both hardware and software, and everything looked fine. After much researching, it turns out that the error was caused by not having IPv6 enabled on the network adapter inside the virtual machine.  I had turned it off because I thought I wouldn’t need it.  I guess Exchange 2010 does.

  • ASP.NET Web API and Simple Value Parameters from POSTed data

    - by Rick Strahl
    In testing out various features of Web API I've found a few oddities in the way that the serialization is handled. These are probably not super common but they may throw you for a loop. Here's what I found. Simple Parameters from Xml or JSON Content Web API makes it very easy to create action methods that accept parameters that are automatically parsed from XML or JSON request bodies. For example, you can send a JavaScript JSON object to the server and Web API happily deserializes it for you. This works just fine:public string ReturnAlbumInfo(Album album) { return album.AlbumName + " (" + album.YearReleased.ToString() + ")"; } However, if you have methods that accept simple parameter types like strings, dates, number etc., those methods don't receive their parameters from XML or JSON body by default and you may end up with failures. Take the following two very simple methods:public string ReturnString(string message) { return message; } public HttpResponseMessage ReturnDateTime(DateTime time) { return Request.CreateResponse<DateTime>(HttpStatusCode.OK, time); } The first one accepts a string and if called with a JSON string from the client like this:var client = new HttpClient(); var result = client.PostAsJsonAsync<string>(http://rasxps/AspNetWebApi/albums/rpc/ReturnString, "Hello World").Result; which results in a trace like this: POST http://rasxps/AspNetWebApi/albums/rpc/ReturnString HTTP/1.1Content-Type: application/json; charset=utf-8Host: rasxpsContent-Length: 13Expect: 100-continueConnection: Keep-Alive "Hello World" produces… wait for it: null. Sending a date in the same fashion:var client = new HttpClient(); var result = client.PostAsJsonAsync<DateTime>(http://rasxps/AspNetWebApi/albums/rpc/ReturnDateTime, new DateTime(2012, 1, 1)).Result; results in this trace: POST http://rasxps/AspNetWebApi/albums/rpc/ReturnDateTime HTTP/1.1Content-Type: application/json; charset=utf-8Host: rasxpsContent-Length: 30Expect: 100-continueConnection: Keep-Alive "\/Date(1325412000000-1000)\/" (yes still the ugly MS AJAX date, yuk! This will supposedly change by RTM with Json.net used for client serialization) produces an error response: The parameters dictionary contains a null entry for parameter 'time' of non-nullable type 'System.DateTime' for method 'System.Net.Http.HttpResponseMessage ReturnDateTime(System.DateTime)' in 'AspNetWebApi.Controllers.AlbumApiController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter. Basically any simple parameters are not parsed properly resulting in null being sent to the method. For the string the call doesn't fail, but for the non-nullable date it produces an error because the method can't handle a null value. This behavior is a bit unexpected to say the least, but there's a simple solution to make this work using an explicit [FromBody] attribute:public string ReturnString([FromBody] string message) andpublic HttpResponseMessage ReturnDateTime([FromBody] DateTime time) which explicitly instructs Web API to read the value from the body. UrlEncoded Form Variable Parsing Another similar issue I ran into is with POST Form Variable binding. Web API can retrieve parameters from the QueryString and Route Values but it doesn't explicitly map parameters from POST values either. Taking our same ReturnString function from earlier and posting a message POST variable like this:var formVars = new Dictionary<string,string>(); formVars.Add("message", "Some Value"); var content = new FormUrlEncodedContent(formVars); var client = new HttpClient(); var result = client.PostAsync(http://rasxps/AspNetWebApi/albums/rpc/ReturnString, content).Result; which produces this trace: POST http://rasxps/AspNetWebApi/albums/rpc/ReturnString HTTP/1.1Content-Type: application/x-www-form-urlencodedHost: rasxpsContent-Length: 18Expect: 100-continue message=Some+Value When calling ReturnString:public string ReturnString(string message) { return message; } unfortunately it does not map the message value to the message parameter. This sort of mapping unfortunately is not available in Web API. Web API does support binding to form variables but only as part of model binding, which binds object properties to the POST variables. Sending the same message as in the previous example you can use the following code to pick up POST variable data:public string ReturnMessageModel(MessageModel model) { return model.Message; } public class MessageModel { public string Message { get; set; }} Note that the model is bound and the message form variable is mapped to the Message property as would other variables to properties if there were more. This works but it's not very dynamic. There's no real easy way to retrieve form variables (or query string values for that matter) in Web API's Request object as far as I can discern. Well only if you consider this easy:public string ReturnString() { var formData = Request.Content.ReadAsAsync<FormDataCollection>().Result; return formData.Get("message"); } Oddly FormDataCollection does not allow for indexers to work so you have to use the .Get() method which is rather odd. If you're running under IIS/Cassini you can always resort to the old and trusty HttpContext access for request data:public string ReturnString() { return HttpContext.Current.Request.Form["message"]; } which works fine and is easier. It's kind of a bummer that HttpRequestMessage doesn't expose some sort of raw Request object that has access to dynamic data - given that it's meant to serve as a generic REST/HTTP API that seems like a crucial missing piece. I don't see any way to read query string values either. To me personally HttpContext works, since I don't see myself using self-hosted code much.© Rick Strahl, West Wind Technologies, 2005-2012Posted in Web Api   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • Storing large data in HTTP Session (Java Application)

    - by Umesh Awasthi
    I am asking this question in continuation with http-session-or-database-approach. I am planning to follow this approach. When user add product to cart, create a Cart Model, add items to cart and save to DB. Convert Cart model to cart data and save it to HTTP session. Any update/ edit update underlying cart in DB and update data snap shot in Session. When user click on view cart page, just pick cart data from Session and display to customer. I have following queries regarding HTTP Session How good is it to store large data (Shopping Cart) in Session? How scalable this approach can be ? (With respect to Session) Won't my application going to eat and demand a lot of memory? Is my approach is fine or do i need to consider other points while designing this? Though, we can control what all cart data should be stored in the Session, but still we need to have certain information in cart data being stored in session?

    - by AaronBertrand
    A long time ago, in a galaxy far, far away... Okay, it was here on earth, a little over 5 years ago. With SQL Server 2005, Microsoft introduced a very useful feature called the DAC. DAC stands for "dedicated administrator connection"... you can read about it here , but essentially, it allows you a single connection into the server with priority resource allocation - so you can actually get in and kill a rogue process that is otherwise taking over the server. On its own this was a fine acronym choice,...(read more)

  • Keyboard Function Keys Do Not Work

    - by Anthony Burman
    I use the Microsoft Natural MultiMedia Keyboard 1.0A. The keyboard is not a wireless board. The Escape button and the function keys have never worked. I am currently running on 10.10. On previous incarnations the keys never worked either. However a recent journey through all the Microsoft options in System Preference Keyboard Layouts suggested that the Escape button could be functional. The current setting is Generic 105-key (Intl) PC. Can I find out whether the keys can be made to work or not? Of the top buttons, nothing happens when I press My Documents; a small red cross appears at the top right of the screen when I press My Pictures and the Media, Mail and Web/Home buttons work just fine. Thanks, Anthony.
