  • "Class ref in pre-verified class resolved to unexpected implementation" when running android tests i

    - by Mike
    I have a module that builds an app called MyApp. I have another that builds some testcases for that app, called MyAppTests. They both build their own APKs, and they both work fine from within my IDE. I'd like to build them using ant so that I can take advantage of continuous integration. Building the app module works fine. I'm having difficulty getting the Test module to compile and run. Using Christopher's tip from a previous question, I used android create test-project -p MyAppTests -m ../MyApp -n MyAppTests to create the necessary build files to build and run my test project. This seems to work great (once I remove an unnecessary test case that it constructed for me and revert my AndroidManifest.xml to the one I was using before it got replaced by android create), but I have two problems. The first problem: The project doesn't compile because it's missing libraries. $ ant run-tests Buildfile: build.xml [setup] Project Target: Google APIs [setup] Vendor: Google Inc.

  • No USB 04b4:0307 mike input after 10.04

    - by Papou
    I am using an USB phone that is in fact a so-called "sound card" based on the 04b4:0307 chip. In fact, I have two different phones using 04b4:0307 and in fact I have a sound USB key too. This, I believe, is the start of why they call 04b4:0307 "ubiquitous" (instead of oh four bee...). But not "eternal". The mike worked in Ubuntu 9.10 and 10.04 but not later ([email protected]). "not working" means that 04b4:0307 shows in Sound Preference but that its vu-meter is mute. I have posted the full lsusb and the result of tests in various systems here: http://www.papou.byethost9.com/tmp/1043601.html Note: Tests done on VirtualBox (thankfully). But UbuntUnity no longer works on VB, so I used the LinuxMint equivalent. ?hat's fate. I could not find any problem report close enough. What should be my next step? I believe the problem occurs in module snd-usb-audio. One thing I might try if I knew how is hacking a DEB with its 10.04's source. I can hack DEBs. Any hint welcome on how to make a DEB overriding a kernel packed module. I mean that the newly installed module should have precedence, be loaded instead, the module installed with the kernel. TIA !

  • Oracle Service Bus JMS Deployments Utility by Mike Muller

    - by JuergenKress
    For proxy services utilizing the JMS transport, OSB receives messages from destinations by using an MDB. These MDBs get generated and deployed during activation of the service configuration. OSB creates a random, unique name for the J2EE application that gets deployed to WLS. The name starts with “_ALSB_” and ends in a unique series of digits. The EAR files are written to the sbgen subdirectory of the domain home directory. You will see these applications on the WLS console page for “Deployments”. For various operational reasons, there are times when the application name for a given proxy service needs to be determined. Since the generated name of the application doesn’t reflect the name of the service, it becomes difficult to determine the relationship between the service and its EAR file. In fact, it can not be discerned from either the OSB or WLS consoles.Read the full article here.

  • A Rose by Any Other Name..

    - by Geoff N. Hiten
    It is always a good start when you can steal a title line from one of the best writers in the English language.  Let’s hope I can make the rest of this post live up to the opening.  One recurring problem with SQL server is moving databases to new servers.  Client applications use a variety of ways to resolve SQL Server names, some of which are not changed easily <cough SharePoint /cough>.  If you happen to be using default instances on both the source and target SQL Server, then the solution is pretty simple.  You create (or bug the network admin until she creates) two DNS “A” records. One points the old name to the new IP address.  The other creates a new alias for the old server, since the original system name is now redirected.  Note this will redirect ALL traffic from the old server to the new server, including RDP and file share connection attempts.    Figure 1 – Microsoft DNS MMC Snap-In   Figure 2 – DNS New Host Dialog Box Both records are necessary so you can still access the old server via an alternate name. Server Role IP Address Name Alias Source 10.97.230.60 SQL01 SQL01_Old Target 10.97.230.80 SQL02 SQL01 Table 1 – Alias List If you or somebody set up connections via IP address, you deserve to have to go to each app and fix it by hand.  That is the only way to fix that particular foul-up. If have to deal with Named Instances either as a source or a target, then it gets more complicated.  The standard fix is to use the SQL Server Configuration Manager (or one of its earlier incarnations) to create a SQL client alias to redirect the connection.  This can be a pain installing and configuring the app on multiple client servers.  The good news is that SQL Server Configuration Manager AND all of its earlier versions simply write a few registry keys.  Extracting the keys into a .reg file makes centralized automated deployment a snap. If the client is a 32-bit system, you have to extract the native key.  If it is a 64-bit, you have to extract the native key and the WoW (32 bit on 64 bit host) key. First, pick a development system to create the actual registry key.  If you do this repeatedly, you can simply edit an existing registry file.  Create the entry using the SQL Configuration Manager.  You must use a 64-bit system to create the WoW key.  The following example redirects from a named instance “SQL01\SQLUtiluty” to a default instance on “SQL02”.   Figure 3 – SQL Server Configuration Manager - Native Figure 3 shows the native key listing. Figure 4 – SQL Server Configuration Manager – WoW If you think you don’t need the WoW key because your app is 64 it, think again.  SQL Server Management Server is a 32-bit app, as are most SQL test utilities.  Always create both keys for 64-bit target systems. Now that the keys exist, we can extract them into a .reg file. Fire up REGEDIT and browse to the following location:  HKLM\Software\Microsoft\MSSQLServer\Client\ConnectTo.  You can also search the registry for the string value of one of the server names (old or new). Right click on the “ConnectTo” label and choose “Export”.  Save with an appropriate name and location.  The resulting file should look something like this: Figure 5 – SQL01_Alias.reg Repeat the process with the location: HKLM\Software\Wow6432Node\Microsoft\MSSQLServer\Client\ConnectTo Note that if you have multiple alias entries, ALL of the entries will be exported.  In that case, you can edit the file and remove the extra aliases. You can edit the files together into a single file.  Just leave a blank line between new keys like this: Figure 6 – SQL01_Alias_All.reg Of course if you have an automatic way to deploy, it makes sense to have an automatic way to Un-deploy.  To delete a registry key, simply edit the .reg file and replace the target with a “-“ sign like so. Figure 7 – SQL01_Alias_UNDO.reg Now we have the ability to move any database to any server without having to install or change any applications on any client server.  The whole process should be transparent to the applications, which makes planning and coordinating database moves a far simpler task.

  • F# and the rose-tinted reflection

    - by CliveT
    We're already seeing increasing use of many cores on client desktops. It is a change that has been long predicted. It is not just a change in architecture, but our notions of efficiency in a program. No longer can we focus on the asymptotic complexity of an algorithm by counting the steps that a single core processor would take to execute it. Instead we'll soon be more concerned about the scalability of the algorithm and how well we can increase the performance as we increase the number of cores. This may even lead us to throw away our most efficient algorithms, and switch to less efficient algorithms that scale better. We might even be willing to waste cycles in order to speculatively execute at the algorithm rather than the hardware level. State is the big headache in this parallel world. At the hardware level, main memory doesn't necessarily contain the definitive value corresponding to a particular address. An update to a location might still be held in a CPU's local cache and it might be some time before the value gets propagated. To get the latest value, and the notion of "latest" takes a lot of defining in this world of rapidly mutating state, the CPUs may well need to communicate to decide who has the definitive value of a particular address in order to avoid lost updates. At the user program level, this means programmers will need to lock objects before modifying them, or attempt to avoid the overhead of locking by understanding the memory models at a very deep level. I think it's this need to avoid statefulness that has led to the recent resurgence of interest in functional languages. In the 1980s, functional languages started getting traction when research was carried out into how programs in such languages could be auto-parallelised. Sadly, the impracticality of some of the languages, the overheads of communication during this parallel execution, and rapid improvements in compiler technology on stock hardware meant that the functional languages fell by the wayside. The one thing that these languages were good at was getting rid of implicit state, and this single idea seems like a solution to the problems we are going to face in the coming years. Whether these languages will catch on is hard to predict. The mindset for writing a program in a functional language is really very different from the way that object-oriented problem decomposition happens - one has to focus on the verbs instead of the nouns, which takes some getting used to. There are a number of hybrid functional/object languages that have been becoming more popular in recent times. These half-way houses make it easy to use functional ideas for some parts of the program while still allowing access to the underlying object-focused platform without a great deal of impedance mismatch. One example is F# running on the CLR which, in Visual Studio 2010, has because a first class member of the pack. Inside Visual Studio 2010, the tooling for F# has improved to the point where it is easy to set breakpoints and watch values change while debugging at the source level. In my opinion, it is the tooling support that will enable the widespread adoption of functional languages - without this support, people will put off any transition into the functional world for as long as they possibly can. Without tool support it will make it hard to learn these languages. One tool that doesn't currently support F# is Reflector. The idea of decompiling IL to a functional language is daunting, but F# is potentially so important I couldn't dismiss the idea. As I'm currently developing Reflector 6.5, I thought it wise to take four days just to see how far I could get in doing so, even if it achieved little more than to be clearer on how much was possible, and how long it might take. You can read what happened here, and of the insights it gave us on ways to improve the tool.

  • Changing font size of legend title in Python pylab rose/polar plot

    - by LaurieW
    I'm trying to change the font size of the title of an existing legend on a rose, or 'polar', plot. Most of the code was written by somebody else, who is away. I've added:- ax.legend(title=legend_title) setp(l.get_title(), fontsize=8) to add the title 'legend_title', which is a variable that the user enters a string for in a a different function that uses this code. The second line of this doesn't return an error but doesn't appear to do anything either. The complete code is below. 'Rose' and 'RoseAxes' are modules/functions written by somebody. Does anyone know of a way to change the legend title font size? I've found some examples for normal plots but can't find any for rose/polar plots. from Rose.RoseAxes import RoseAxes from pylab import figure, title, setp, close, clf from PlotGeneration import color_map_xml fig = figure(1) rect = [0.02, 0.1, 0.8, 0.8] ax = RoseAxes(fig, rect, axisbg='w') fig.add_axes(ax) if cmap == None: (XMLcmap,colors) = color_map_xml.get_cmap('D:/HRW/VET/HrwPyLibs/ColorMapLibrary/paired.xml',255) else: XMLcmap = cmap bqs = kwargs.pop('CTfigname', None) ax.box(Dir, U, bins = rose_binX, units = unit, nsector = nsector, cmap = XMLcmap, lw = 0, **kwargs ) l = ax.legend() ax.legend(title=legend_title) setp(l.get_texts(), fontsize=8) setp(l.get_title(), fontsize=8) Thanks for any help

  • Mike Cohn-style burndown charts in JIRA

    - by Fuzzy Purple Monkey
    We use Jira/Greenhopper for our project planning/tracking. The built-in graphs are great, but when a new issue/story is added during a project, the whole burn-down graph moves up rather than increasing the part of the graph when the issue was added. Ideally I'd like to generate a Mike Cohn-style burndown graph, which shows a hump when new issues are added. Does anyone know of any plugins that support this, or been able to extract this data directly from the database?

  • Visual Modeler in VS 6

    - by Yogi Yang 007
    Till date I have used only VB6 Professional for developing apps. But recently I have joined a company which owns VS 6 Enterprise (or some such version) I was just exploring what is available in VS 6 Ent. and I found Visual Modeler. The tutorial provided with it is not good enough. I was wondering if there is any detailed tutorial(s) for Visual Modeler? Is Visual Modeler a cut down version of Rational Rose? I have never used such a tool for developing apps. What are the benefits of developing apps like this? The document claims that one can speed up development and modifications of VB6 & VC++ 6 applications. How true is this claim? My company also has Ration Rose 6. Which is better Rational Rose 6 or Visual Modeler that comes with VS 6 Ent.?

  • What&rsquo;s wrong with See[Mike]Code? (no relation)

    - by mbcrump
    I have been hearing a lot about the website See[Mike]Code. Basically, the site creates an interview url and a job candidate url and lets you see the potential programmer’s code (specifically .NET developer). Below is the candidate’s URL   Below is the interviewer url   So you might think, ah, this is a good thing. We can screen candidates cheaper and more efficiently. In reality, this is only a good thing if you want your programmer to develop using notepad.  I use the most efficient tools that exist to do my job. I would simply fire up VS2010 and type “for” and hit the tab key twice and get the following template.   I have no problem keeping MSDN/Google in one of my monitors. I spend time learning VS macros and using Aurora XAML/Expression to produce my XAML for WPF. Sure, I can write a for loop without using the VS Macro, but the real question is, “Why should I?”. My point being, if you really want to test a .NET programmer knowledge then fire up his native working environment and let him use the features of the IDE to develop the simple 10-line program. For a more sophisticated program, then give him 20 minutes and allow access to msdn/google. If the programmer cannot find at the right path then give him the boot.

  • Unable to install updates on 14.04 LTS

    - by Mike
    I have been getting update notifications for a few weeks now but whenever I attempt to install them I get this message; The upgrade needs a total of 74.6 M free space on disk '/boot'. Please free at least an additional 29.8 M of disk space on '/boot'. Empty your trash and remove temporary packages of former installations using 'sudo apt-get clean'. First of all I don't have permission to access /boot (don't know why as its a standalone machine and i'm the only user). Secondly, I emptied the trash; Thirdly, I launched Terminal and entered sudo apt-get clean I was a asked for a sudo password. I entered my system password. Re-entered sudo apt-get clean. The cursor stopped blinking - I assumed it was doing it's "thing". I let it go for about 10 minutes then exited Terminal. Tried to install the updates but just got the same message. Is there something i'm ignorant of? This is the output I get from the command df -h and I have no idea what it all means! @Tim, What's bash and why am I denied access to fstab and /boot? mike@mike-MS-7800:~$ /etc/fstab bash: /etc/fstab: Permission denied mike@mike-MS-7800:~$ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/ubuntu--vg-root 913G 11G 856G 2% / none 4.0K 0 4.0K 0% /sys/fs/cgroup udev 1.7G 4.0K 1.7G 1% /dev tmpfs 335M 1.6M 333M 1% /run none 5.0M 4.0K 5.0M 1% /run/lock none 1.7G 14M 1.7G 1% /run/shm none 100M 52K 100M 1% /run/user /dev/sda2 237M 182M 43M 81% /boot /dev/sda1 487M 3.4M 483M 1% /boot/efi /dev/sr1 31M 31M 0 100% /media/mike/Optus Mobile mike@mike-MS-7800:~$ I ran this from the terminal and all is now working. dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge

  • Alternative site to Mike Gunderloy's "The Daily Grind" (Larkware)?

    - by splattne
    As a developer who is always looking for new resources and information, I loved Mike Gunderloy's blog "The Daily Grind" on www.larkware.com ("We get up early, so you don't have to.") Unfortunately (for me) Mike decided to discontinue the blog in December 2007. So, my question: is there a similar blog / site which provides such good links and resources on a daily basis? I couldn't find one. Thanks! Update: to be clear: I am specifically looking for a site like larkware.com, a kind of aggregator/meta-site of information about interesting articles, components, software for (.NET) developers.
