  • Soft keyboard does not show when Activity starts

    - by Sarp Centel
    I have added android:windowSoftInputMode="stateAlwaysVisible" to my Activity in AndroidManifest.xml and here's my layout: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <EditText android:id="@+id/EditText01" android:layout_width="wrap_content" android:layout_height="wrap_content"></EditText> <EditText android:id="@+id/EditText02" android:layout_width="wrap_content" android:layout_height="wrap_content"></EditText> <Button android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Send"></Button> </LinearLayout> When the Activity starts, the EditText is focused, but soft keyboard isn't displayed. If I click on the EditText, then I see the soft keyboard. Do I need to set aditional parameters to display soft keyboard when my Activity starts? Thanks

  • iPad: How To Soft Reset, Restore Factory Settings And Erase All Content

    - by Gopinath
    iPad is an amazing gadget from Apple and everyone of us loves to own it. If you are a lucky one to own an iPad here are some basic troubleshooting features that you should be aware. There is no doubt that iPad is an amazing gadget, but similar to other electronic gadgets it refuses to work now and then. When your iPad hangs or refuses to respond you can soft reset it by holding the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. This just reset your iPad and it’s similar to force rebooting your PC. All your settings and data are untouched during this process. The embedded video below shows how to turn off and soft reset an iPad. If iPad Doesn’t Work After Soft Reset – Restore Factory Settings Soft reset should resolve most of the iPad issues like hanging, not responding properly, etc. In case even if your iPad does not work properly after soft reset you can try reset all the setting to factory defaults by navigating through the Home screen > Settings > General > Reset > Reset All Settings.  This will reset all your settings and other iPad customizations to factory defaults but your data(images, documents, apps, etc.) are left untouched. How To Erase All Content Of iPad You may ask why should I erase all the content of iPad? Well may be you are willing to sell it off on eBay by erasing all the content or you want start afresh or some other reason. It is easy to reset all the settings of iPad as well as wipe out all content by navigating through Home screen > General > Reset >  “Erase All Content and Settings.” CC Image credit flickr/korosirego This article titled,iPad: How To Soft Reset, Restore Factory Settings And Erase All Content, was originally published at Tech Dreams.

  • WPF: Soft deletes and binding?

    - by aks
    I have custom objects which implement INotifyProperyChanged and now I'm wondering if it is possible to implement soft delete which would play nicely with binding? Each object would have a IsDeleted property and if this property would be set to true than it would not be displayed in GUI. I was thinking about making a custom markup extension which would decorate Binding class but it hadn't worked out as expected. Now I'm considering using MultiBinding with IsDeleted as one of bound properties so that converter would be able to figure out which object is deleted. But this solution sounds quite complicated and boring. Does anybody have an idea how to implement soft deletes for binding?

  • The Red Gate and .NET Reflector Debacle

    - by Rick Strahl
    About a month ago Red Gate – the company who owns the NET Reflector tool most .NET devs use at one point or another – decided to change their business model for Reflector and take the product from free to a fully paid for license model. As a bit of history: .NET Reflector was originally created by Lutz Roeder as a free community tool to inspect .NET assemblies. Using Reflector you can examine the types in an assembly, drill into type signatures and quickly disassemble code to see how a particular method works.  In case you’ve been living under a rock and you’ve never looked at Reflector, here’s what it looks like drilled into an assembly from disk with some disassembled source code showing: Note that you get tons of information about each element in the tree, and almost all related types and members are clickable both in the list and source view so it’s extremely easy to navigate and follow the code flow even in this static assembly only view. For many year’s Lutz kept the the tool up to date and added more features gradually improving an already amazing tool and making it better. Then about two and a half years ago Red Gate bought the tool from Lutz. A lot of ruckus and noise ensued in the community back then about what would happen with the tool and… for the most part very little did. Other than the incessant update notices with prominent Red Gate promo on them life with Reflector went on. The product didn’t die and and it didn’t go commercial or to a charge model. When .NET 4.0 came out it still continued to work mostly because the .NET feature set doesn’t drastically change how types behave.  Then a month back Red Gate started making noise about a new Version Version 7 which would be commercial. No more free version - and a shit storm broke out in the community. Now normally I’m not one to be critical of companies trying to make money from a product, much less for a product that’s as incredibly useful as Reflector. There isn’t day in .NET development that goes by for me where I don’t fire up Reflector. Whether it’s for examining the innards of the .NET Framework, checking out third party code, or verifying some of my own code and resources. Even more so recently I’ve been doing a lot of Interop work with a non-.NET application that needs to access .NET components and Reflector has been immensely valuable to me (and my clients) if figuring out exact type signatures required to calling .NET components in assemblies. In short Reflector is an invaluable tool to me. Ok, so what’s the problem? Why all the fuss? Certainly the $39 Red Gate is trying to charge isn’t going to kill any developer. If there’s any tool in .NET that’s worth $39 it’s Reflector, right? Right, but that’s not the problem here. The problem is how Red Gate went about moving the product to commercial which borders on the downright bizarre. It’s almost as if somebody in management wrote a slogan: “How can we piss off the .NET community in the most painful way we can?” And that it seems Red Gate has a utterly succeeded. People are rabid, and for once I think that this outrage isn’t exactly misplaced. Take a look at the message thread that Red Gate dedicated from a link off the download page. Not only is Version 7 going to be a paid commercial tool, but the older versions of Reflector won’t be available any longer. Not only that but older versions that are already in use also will continually try to update themselves to the new paid version – which when installed will then expire unless registered properly. There have also been reports of Version 6 installs shutting themselves down and failing to work if the update is refused (I haven’t seen that myself so not sure if that’s true). In other words Red Gate is trying to make damn sure they’re getting your money if you attempt to use Reflector. There’s a lot of temptation there. Think about the millions of .NET developers out there and all of them possibly upgrading – that’s a nice chunk of change that Red Gate’s sitting on. Even with all the community backlash these guys are probably making some bank right now just because people need to get life to move on. Red Gate also put up a Feedback link on the download page – which not surprisingly is chock full with hate mail condemning the move. Oddly there’s not a single response to any of those messages by the Red Gate folks except when it concerns license questions for the full version. It puzzles me what that link serves for other yet than another complete example of failure to understand how to handle customer relations. There’s no doubt that that all of this has caused some serious outrage in the community. The sad part though is that this could have been handled so much less arrogantly and without pissing off the entire community and causing so much ill-will. People are pissed off and I have no doubt that this negative publicity will show up in the sales numbers for their other products. I certainly hope so. Stupidity ought to be painful! Why do Companies do boneheaded stuff like this? Red Gate’s original decision to buy Reflector was hotly debated but at that the time most of what would happen was mostly speculation. But I thought it was a smart move for any company that is in need of spreading its marketing message and corporate image as a vendor in the .NET space. Where else do you get to flash your corporate logo to hordes of .NET developers on a regular basis?  Exploiting that marketing with some goodwill of providing a free tool breeds positive feedback that hopefully has a good effect on the company’s visibility and the products it sells. Instead Red Gate seems to have taken exactly the opposite tack of corporate bullying to try to make a quick buck – and in the process ruined any community goodwill that might have come from providing a service community for free while still getting valuable marketing. What’s so puzzling about this boneheaded escapade is that the company doesn’t need to resort to underhanded tactics like what they are trying with Reflector 7. The tools the company makes are very good. I personally use SQL Compare, Sql Data Compare and ANTS Profiler on a regular basis and all of these tools are essential in my toolbox. They certainly work much better than the tools that are in the box with Visual Studio. Chances are that if Reflector 7 added useful features I would have been more than happy to shell out my $39 to upgrade when the time is right. It’s Expensive to give away stuff for Free At the same time, this episode shows some of the big problems that come with ‘free’ tools. A lot of organizations are realizing that giving stuff away for free is actually quite expensive and the pay back is often very intangible if any at all. Those that rely on donations or other voluntary compensation find that they amount contributed is absolutely miniscule as to not matter at all. Yet at the same time I bet most of those clamouring the loudest on that Red Gate Reflector feedback page that Reflector won’t be free anymore probably have NEVER made a donation to any open source project or free tool ever. The expectation of Free these days is just too great – which is a shame I think. There’s a lot to be said for paid software and having somebody to hold to responsible to because you gave them some money. There’s an incentive –> payback –> responsibility model that seems to be missing from free software (not all of it, but a lot of it). While there certainly are plenty of bad apples in paid software as well, money tends to be a good motivator for people to continue working and improving products. Reasons for giving away stuff are many but often it’s a naïve desire to share things when things are simple. At first it might be no problem to volunteer time and effort but as products mature the fun goes out of it, and as the reality of product maintenance kicks in developers want to get something back for the time and effort they’re putting in doing non-glamorous work. It’s then when products die or languish and this is painful for all to watch. For Red Gate however, I think there was always a pretty good payback from the Reflector acquisition in terms of marketing: Visibility and possible positioning of their products although they seemed to have mostly ignored that option. On the other hand they started this off pretty badly even 2 and a half years back when they aquired Reflector from Lutz with the same arrogant attitude that is evident in the latest episode. You really gotta wonder what folks are thinking in management – the sad part is from advance emails that were circulating, they were fully aware of the shit storm they were inciting with this and I suspect they are banking on the sheer numbers of .NET developers to still make them a tidy chunk of change from upgrades… Alternatives are coming For me personally the single license isn’t a problem, but I actually have a tool that I sell (an interop Web Service proxy generation tool) to customers and one of the things I recommend to use with has been Reflector to view assembly information and to find which Interop classes to instantiate from the non-.NET environment. It’s been nice to use Reflector for this with its small footprint and zero-configuration installation. But now with V7 becoming a paid tool that option is not going to be available anymore. Luckily it looks like the .NET community is jumping to it and trying to fill the void. Amidst the Red Gate outrage a new library called ILSpy has sprung up and providing at least some of the core functionality of Reflector with an open source library. It looks promising going forward and I suspect there will be a lot more support and interest to support this project now that Reflector has gone over to the ‘dark side’…© Rick Strahl, West Wind Technologies, 2005-2011

  • How to combine Translate and Soft Deletable Behavior in CakePHP 1.2.7?

    - by m99
    Hi guys, i'm trying to combine Translate Behavior and Mariano Iglesias' Soft Deletable Behavior Revision 49. But always if a want to soft delete a record which hasMany other records, which are translated (located in the i18n-table partly), the related hasMany records aren't soft deleted. Example: Post hasMany Comments (dependent = true) Post actsAs SoftDeletable Comments actsAs SoftDeletable, Translate Post record get's soft deleted, but I also get an error for the dependent Comment records and they aren't soft deleted. Any suggestions? Thanks in advance Marco

  • LINQ to SQL: filter nested objects with soft deletes

    - by Alex
    Hello everyone, I'm using soft deleting in my database (IsDeleted field). I'm actively using LoadWith and AssociateWith methods to retrieve and filter nested records. The thing is AssociateWith only works with properties that represents a one-to-many relationship. DataLoadOptions loadOptions = new DataLoadOptions(); loadOption.LoadWith<User>(u = > u.Roles); loadOption.AssociateWith<User>(u = > u.Roles.Where(r = > !r.IsDeleted)); In the example above I just say: I want to retrieve users with related (undeleted) roles. But when I have one-to-one relationship, e.g. Document - File (the only one file is related to the document) I'm unable to filter soft deleted object: DataLoadOptions loadOptions = new DataLoadOptions(); loadOption.LoadWith<Document>(d = > d.File); // the next certainly won't work loadOption.AssociateWith<File>(f = > !f.IsDeleted); So, is there any idea how to filter records within the one-to-one relationship? Thanks!

  • Memory mapped files and "soft" page faults. Unavoidable?

    - by Robert Oschler
    I have two applications (processes) running under Windows XP that share data via a memory mapped file. Despite all my efforts to eliminate per iteration memory allocations, I still get about 10 soft page faults per data transfer. I've tried every flag there is in CreateFileMapping() and CreateFileView() and it still happens. I'm beginning to wonder if it's just the way memory mapped files work. If anyone there knows the O/S implementation details behind memory mapped files I would appreciate comments on the following theory: If two processes share a memory mapped file and one process writes to it while another reads it, then the O/S marks the pages written to as invalid. When the other process goes to read the memory areas that now belong to invalidated pages, this causes a soft page fault (by design) and the O/S knows to reload the invalidated page. Also, the number of soft page faults is therefore directly proportional to the size of the data write. My experiments seem to bear out the above theory. When I share data I write one contiguous block of data. In other words, the entire shared memory area is overwritten each time. If I make the block bigger the number of soft page faults goes up correspondingly. So, if my theory is true, there is nothing I can do to eliminate the soft page faults short of not using memory mapped files because that is how they work (using soft page faults to maintain page consistency). What is ironic is that I chose to use a memory mapped file instead of a TCP socket connection because I thought it would be more efficient. Note, if the soft page faults are harmless please note that. I've heard that at some point if the number is excessive, the system's performance can be marred. If soft page faults intrinsically are not significantly harmful then if anyone has any guidelines as to what number per second is "excessive" I'd like to hear that. Thanks.

  • Red Gate and the Community

    - by RedAndTheCommunity
    I was lucky enough to join the Communities team in April 2011, having worked in the equally awesome (but more number-crunchy), Finance team at Red Gate for about four years before that. Being totally passionate about Red Gate, and easily excitable, it seems like the perfect place to be. Not only do I get to talk to people who love Red Gate every day, I get to think up new ways to make them love us even more. Red Gate sponsored 178 SQL Server and .NET events and user group meetings in 2011. They ranged from SQL Saturdays and Code Camps to 10 person user group meetings, from California to Krakow. We've given away cash, software, Kindles, and of course swag. The Marketing Cupboard is like a wonderland of Red Gate goodies; it is guarded day and night to make sure the greedy Red Gaters don't pilfer the treasure inside. There are Red Gate yo-yos, books, pens, ice scrapers and, over the Holidays, there were some special bears. We had to double the patrols guarding the cupboard to protect them. You can see why: Over the Holidays, we gave funding and special Holiday swag (including the adorable bears), to 10 lucky user groups, who held Christmas parties - doing everything from theatre trips to going to shooting ranges. What next? So, what about this year? In 2012 our main aim is to be out there meeting more of you. So get ready to see an army of geeks in red t-shirts at your next event! We also want to do more fun things like our Christmas party giveaway. What cool ideas do you have for sponsorship in 2012? An Easter Egg hunt with SQL server clues? A coding competition? A duelling contest with a license of SQL Toolbelt for the winner? Let me know.

    I was looking for a way to avoid deleting my users from DB, but instead to mark them as deleted and don't bring them back in queries. I found this plugin http://grails.org/plugin/hibernate-filter, which was a great tool for the task. But when I tried to implement my solution, I passed trought same problems whose solutions wheren't (or I was not able to find) on internet. So, next, I describe the way that I solve the problem of soft delete.

  • A Couple Android Soft Keyboard Questions

    - by Rich
    This is kind of a repost, and I apologize for any broken rules, but I have a couple of questions about the soft keyboard on Android phones: 1) I have an Android app with a couple different views (that the user switches between). How can I determine which is the current view?? I need to get the current view to execute the code that hides the virtual keyboard. 2) How can I check whether the virtual keyboard is currently being displayed (so I can filter the actions of my various hard keys)?? Thanks, R.

  • Show soft keyboard when Activity starts

    - by Al
    I have 2 activities, A and B. When A starts, it checks for a condition and if true, it calls startActivityForResult() to start B. B only takes text input so it makes sense for the soft keyboard to automatically pop up when B start. When the activity starts, the EditText already has focus and it ready for input. The problem is that the keyboard never shows up, even with windowSoftInputMode="stateAlwaysVisible" set in the manifest under the <activity> tag for B. I also tried with the value set to stateVisible. Since it doesn't show up automatically, I have to tap the EditText to make it show. Anyone know what the solution might be?

  • Hide Soft Keyboard Not Working ...

    - by stormin986
    I'm developing on the Droid Incredible (and have tested on a 1.5 AVD Emulator as well), and one of the tabs in my tab widget consists of a listview and a row with an EditText and a Send button (for a chat feature). I am using the following to close the soft keyboard once I click Send, but it's not working. This is identical to code I've found elsewhere that people have upvoted as correct. See anything I'm missing? // in Button's onClick(): EditText chatTextBox = (EditText) findViewById(R.id.chat_entry); // Handle button click ... chatTextBox.setText(""); InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); imm.hideSoftInputFromInputMethod(chatTextBox.getWindowToken(), InputMethodManager.HIDE_IMPLICIT_ONLY); I also tried changing the flag to 0. No luck. Anyone know what's up??

  • How to test soft deletion event listner without setting up NHibernate Sessions

    - by isuruceanu
    I have overridden the default NHibernate DefaultDeleteEventListener according to this source: http://nhforge.org/blogs/nhibernate/archive/2008/09/06/soft-deletes.aspx so I have protected override void DeleteEntity( IEventSource session, object entity, EntityEntry entityEntry, bool isCascadeDeleteEnabled, IEntityPersister persister, ISet transientEntities) { if (entity is ISoftDeletable) { var e = (ISoftDeletable)entity; e.DateDeleted = DateTime.Now; CascadeBeforeDelete(session, persister, entity, entityEntry, transientEntities); CascadeAfterDelete(session, persister, entity, transientEntities); } else { base.DeleteEntity(session, entity, entityEntry, isCascadeDeleteEnabled, persister, transientEntities); } } How can I test only this piece of code, without configuring an NHIbernate Session?

  • Friend of Red Gate

    - by Nick Harrison
    Friend of Red Gate I recently joined the friend of Red Gate program.   I am very honored to be included in this group.    This program is a big part of Red Gates community outreach.   If you are not familiar with Red Gate, I urge you to check them out.    They have some wonderful tools for the SQL Server community and the DotNet community.    They are also building up some tools for Exchange and Oracle. I was invited to join this program primarliy because of my work with Simple Talk and promoting one of their newest products, Reflector. Reflector is a wonderful tool.   I doubt that anyone who has ever used it would argue that point. Red Gate did a wonderful job taking over the support of Reflector.   I know many people had their doubts.    The initial release under Red Gate should set those fears to rest.   I was very impressed with how their developers interacted with their users during the preview phase! Red Gate is also a good partner for the community.    They activly support the community, sponsoring Code Camps, sponsoring User Groups, supporting the Forums, etc. And their tools are pretty amazing as well.

  • red-black tree - construction

    - by Chaitanya
    Recently, I have been going through search trees and I encountered red-black trees, the point confusing me is, In r-b tree, the root node should be black thats fine, now how will I decide whether the incoming node assumes red or black color. I have gone through the wiki article but have not found a solution for this. I might be wrong, but I would be happy if someone can guide me through the exact material. Thank you.

  • Red-Black trees - Erasing a node with two non-leaf children

    - by SalamiArmi
    Hi all, I've been implementing my own version of a red-black tree, mostly basing my algorithms from Wikipedia (http://en.wikipedia.org/wiki/Red-black_tree). Its fairly concise for the most part, but there's one part that I would like clarification on. When erasing a node from the tree that has 2 non-leaf (non-NULL) children, it says to move either side's children into the deletable node, and remove that child. I'm a little confused as to which side to remove from, based on that. Do I pick the side randomly, do I alternate betweek sides, or do I stick to the same side for every future deletion?

  • Red Gate does Byte Night 2012

    - by red(at)work
    On the 5th of October 2012, a team of nine plucky Red Gaters braved the howling wind and the driving rain to sleep outside. No tents or mattresses were allowed – all we took for protection were sleeping bags, groundsheets, plastic sacks and Colin’s enormous fishing umbrella (a godsend in umbrella-y disguise). Why would we do such a thing? For Byte Night, an annual tech sector sleepout in support of Action for Children, who tackle the causes as well as the consequences of youth homelessness. Byte Night encourages technology professionals to do for one night a year what thousands of young people have to do every night – sleep rough.  We signed up for Byte Night in the warm, heady midst of the British summer, thinking it couldn’t possibly be all that bad. Even on the night itself – before the rain began to fall, sat in the comfort and warmth of a company canteen, drinking wine and eating chill and preparing to win the pub quiz – we were excited and optimistic about the night that lay ahead of us. All of that changed as soon as we stepped out into one of the worst rainstorms of the year. Brian, the team’s birthday boy, describes it best: Picture the scene: it’s 3 am on a Friday. I’m lying outside, fully clothed in a sleeping bag, wearing a raincoat, trussed up inside a large plastic pocket, on a ground sheet beneath a giant umbrella, wedged so tightly between two of my colleagues that I can’t move my arms. I’m wide awake, staring up at the grey sky beyond the edge of the umbrella; a limp, flickering white glow hints at a moon somewhere behind the drifting clouds. I haven’t slept since we first moved outside at 11 pm. Outside. Did I mention we were outside? I’m hung over. I need the loo. But there is no way on earth that I’m getting out of this sleeping bag. It’s cold. It’s raining. Not just raining, but chucking it down. It’s been doing this non-stop since 10pm. The rain sounds like a hyperactive drummer on the fishing umbrella, and the noise is loud and relentless. Puddles of water are forming all over the groundsheet, and, despite being ensconced inside the plastic pouch, I am wet. The fishing umbrella is protecting me from the worst of the driving rain, but not all of me is under it, and five hours of rain is no match for it. Everything is wet. My left side has become horribly damp. My trainers, which I placed next to my sleeping bag, are now completely soaked through. Mmm. That’ll be fun in the morning. My head is next to Colin’s head on one side, and a multi-pack of McCoy’s cheddar and onion crisps on the other. Don’t ask about the tub of hummus. That’s somewhere down by my ankles, abandoned to the night. Jess, who is lying next to me, rolls over onto her side. A mini waterfall cascades from her rain-pouch onto my face. Bah. I continue to stare into the heavens, willing the dawn to hurry up. Something lands on my face. It’s a mosquito. Great. Midnight, when this still seemed like fun – when we opened some champagne and my colleagues presented me with a caterpillar birthday cake, when everyone was drunk and jolly and full of stoic resolve – feels like a long time ago. Did I mention that today is my birthday? The remains of the caterpillar cake endure the same fate as the hummus, left out in the rain like a metaphor for sadness. It’s getting colder. I can see my breath. Silence has descended on the group, apart from the rustle of plastic. And the rain, obviously. Someone snores, and I envy whoever it is the sweet escape of sleep. I try to wriggle a bit further down inside my sleeping bag, but it doesn’t want to be wriggled into. Only 3 hours till dawn. 180 minutes. I begin to count them off, one at a time.  All nine of us got to go home in the morning, but thousands of children across the UK don’t have that luxury. If you’d like to sponsor the Red Gate Byte Night team, our JustGiving page can be found here.   Chris, before the outside bit actually happened. More photos from Byte Night Cambridge 2012 can be found here.

  • Soft lockup after upgrade - cannot install from live CD

    - by nbm
    I dual-boot MacIntel Core 2 duo. nVidia graphics. Ran upgrade from ubuntu 13.10 to 14.04 (64 bit). On restart ran into {numbers} Bug: soft lockup - CPU#0 stuck for 22s! [swapper/0:1] Tried loading earlier kernel: same problem Tried re-installing ubuntu from a liveCD that has worked in the past: version 13.04. Same problem. Tried re-partitioning hard drive using Mac OS X disk utility and then installing ubuntu 14.04LTS from liveCD. Same problem. Not possible to verify liveCD disk (creates same "soft lockup" bug.) Tried installing from the liveCD with version 13.04 that I know works (that's how I got Ubuntu on this machine in the first place.) Same problem. I know this is not a hardware problem as OS X works just fine, I am using it right now on the same machine. I have been using various versions of Ubuntu for 2 years. Things I cannot do: Open a terminal Verify CD image Start ubuntu from CD (same soft lockup problem) This problem is similar to some other questions, none of which have been satisfactorily answered: Ubuntu 14.04 soft lockup on Vostro 3500 Cannot do fresh install of Ubuntu 13.04 while booting from DVD: "soft lockup" bug Live CD stalls when installing Ubuntu 13.10 UPDATE 6/11/14: Following some much-appreciated advice from bain (see below) I burned a 12.04LTS disk and started with kernel parameters: noapic, no1apic, acpi=off, nomodeset, elevator=deadline, and clocksource=jiffies. With all of these parameters I was able to load the 12.04LTS CD ("Try without installing"). It worked fine. However, as soon as I tried to install Ubuntu from the CD, my wired ethernet (eth0) connection would hang. There are already various askubuntu questions and bug reports about this problem, none of which had answers for me. (E.g., dhclient eth0 does nothing, none of the various reset commands does anything, manually setting IP &etc does nothing. I could reliably kill the ethernet connection by clicking "install ubuntu" every single time.) I could go ahead and install 12.04 without an internet connection, but the install would freeze after mostly completing (I tried several times.) There were some relevant error messages in the details of the install output script that, IIRC, had to do with searching for missing files and not being able to access eth0 (internet) to get them. To be honest I gave up at that point and I'm not sure I wrote those down. If I find some notes I will post them. At this point I no longer have Ubuntu on my system. I wiped the partitions and am using exclusively OS X. I am leaving this question in case it helps anyone else with similar problems. I love open source and I love Linux, and the next machine I get I will probably just build from Arch. At the moment I miss repositories and a lot of other things about Ubuntu, but the OS X terminal is 'nix, I can pretty much use all the open source apps I like, and while I am not a fan of the Apple software it gets the job done for me. Unlike Ubuntu, which can't even install. I realize this isn't necessarily a place for a soapbox speech, but when I first installed 12.04 several years ago there were already people in the community complaining that Canonical was going too "commercial". But I loved it. Several years later and all I've seen is Canonical adding more not-so-useful bells and whistles to Ubuntu while continually failing to fix basic problems on upgrades. With a dual-boot (and sometimes triple-boot) system it always took me some tweaking to get an upgrade to work, and to some extent that is okay. But at this point I feel like Canonical ought to just put a price tag on Ubuntu. All I see is more commercialism and advertising and product tie-ins, and ongoing problems do not get fixed. I am a big fan of open-source, not-for profit enterprise. I am also a big fan of for-profit enterprise, which certainly has its place and usefulness. I am not a fan of companies who pretend to be in favor of open source but really are just out to make a buck, and IMNSHO that is what Canonical has become. This is a great community and I wish you all the best, but my next install of Linux will not be Ubuntu.

  • TDD - Red-Light-Green_Light:: A critical view

    - by Renso
    Subject: The concept of red-light-green-light for TDD/BDD style testing has been around since the dawn of time (well almost). Having written thousands of tests using this approach I find myself questioning the validity of the principle The issue: False positive or a valid test strategy that can be trusted? A critical view: I agree that the red-green-light concept has some validity, but who has ever written 2000 tests for a system that goes through a ton of chnages due to the organic nature fo the application and does not have to change, delete or restructure their existing tests? If you asnwer to the latter question is" "Yes I had a situation(s) where I had to refactor my code and it caused me to have to rewrite/change/delete my existing tests", read on, else press CTRL+ALT+Del :-) Once a test has been written, failed the test (red light), and then you comlpete your code and now get the green light for the last test, the test for that functionality is now in green light mode. It can never return to red light again as long as the test exists, even if the test itself is not changed, and only the code it tests is changed to fail the test. Why you ask? because the reason for the initial red-light when you created the test is not guaranteed to have triggered the initial red-light result for the same reasons it is now failing after a code change has been made. Furthermore, when the same test is changed to compile correctly in case of a compile-breaking code change, the green-light once again has been invalidated. Why? Because there is no guarantee that the test code fix is in the same green-light state as it was when it first ran successfully. To make matters worse, if you fix a compile-breaking test without going through the red-light-green-light test process, your test fix is essentially useless and very dangerous as it now provides you with a false-positive at best. Thinking your code has passed all tests and that it works correctly is far worse than not having any tests at all, well at least for that part of the system that the test-code represents. What to do? My recommendation is to delete the tests affected, and re-create them from scratch. I have to agree. Hard to do and justify if it has a significant impact on project deadlines. What do you think?

  • That’s a wrap! Almost, there’s still one last chance to attend a SQL in the City event in 2012

    - by Red and the Community
    The communities team are back from the SQL in the City multi-city US Tour and we are delighted to have met so many happy SQL Server professionals and Red Gate customers. We set out to run a series of back-to-back events in order to meet, talk to and delight as many SQL Server and Red Gate enthusiasts as possible in 5 different cities in 11 days. We did it! The attendees had a good time too and 99% of them would attend another SQL in the City event in 2013 – so it seems we left an impression. There were a range of topics on the event agenda, ranging from ‘The Whys & Hows of Continuous Integration’, ‘Database Maintenance Essentials’, ‘Red Gate tools – The Complete Lifecycle’, ‘Automated Deployment: Application And Database Releases Without The Headache’, ‘The Ten Commandments of SQL Server Monitoring’ and many more. Videos and slides from the events will be posted to the event website in November, after our last event of 2012. SQL in the City Seattle – November 5 Join us for free and hear from some of the very best names in the SQL Server world. SQL Server MVPs such as; Steve Jones, Grant Fritchey, Brent Ozar, Gail Shaw and more will be presenting at the Bell Harbor conference center for one day only. We’re even taking on board some of the recent attendee-suggestions of how we can improve the events (feedback from the 65% of attendees who came to our US tour events), first off we’re extending the drinks celebration in the evening! Rather than just a 30 minute drink and run, attendees will have up to 2 hours to enjoy free drinks, relax and network in a fantastic environment amongst some really smart like-minded professionals. If you’re interested in expanding your SQL Server knowledge, would like to learn more about Red Gate tools, get yourself registered for the last SQL in the City event of 2012. It’s free, fun and we’re very friendly! I look forward to seeing you in Seattle on Monday November 5. Cheers, Annabel.
