warning BC40056: Namespace or type specified in the Imports 'MS.Internal.Xaml.Builtins' doesn't cont

- by Heinzi

I have a WPF VB.NET project in Visual Studio 2008. For some reason, Visual Studio thinks that it needs to add an Imports MS.Internal.Xaml.Builtins to every auto-generated XAML partial class (= the nameOfXamlFile.g.vb files), resulting in the following warning: warning BC40056: Namespace or type specified in the Imports 'MS.Internal.Xaml.Builtins' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases. I can remove the Imports line, but, since this is an auto-generated file, it reappears every time that the project is rebuilt. This warning message is annoying and clutters my error list. Is ther something that can be done about it? Or is it a known bug?

Does using GCC specific builtins qualify as incorporation within a project?

- by DavidJFelix

I understand that linking to a program licensed under the GPL requires that you release the source of your program under the GPL as well, while the LGPL does not require this. The terminology of the (L)GPL is very clear about this. #include "gpl_program.h" means you'd have to license GPL, because you're linking to GPL licensed code. And #include "lgpl_program.h" means you're free to license however you want, so that it doesn't explicitly prohibit linking to LGPL source. Now, my question about what isn't clear is: [begin question] GCC is GPL licensed, compiling with GCC, does not constitute "integration" into your program, as the GPL puts it; does using builtin functions (which are specific to GCC) constitute "incorporation" even though you haven't explicitly linked to this GPL licensed code? My intuition tells me that this isn't the intention, but legality isn't always intuitive. I'm not actually worried, but I'm curious if this could be considered the case. [end question] [begin aside] The reason for my equivocation is that GCC builtins like __builtin_clzl() or __builtin_expect() are an API technically and could be implemented in another way. For example, many builtins were replicated by LLVM and the argument could be made that it's not implementation specific to GCC. However, many builtins have no parallel and when compiled will link GPL licensed code in GCC and will not compile on other compilers. If you make the argument here that the API could be replicated by another compiler, couldn't you make that identical claim about any program you link to, so long as you don't distribute that source? I understand that I'm being a legal snake about this, but it strikes me as odd that the GPL isn't more specific. I don't see this as a reasonable ploy for proprietary software creators to bypass the GPL, as they'd have to bundle the GPL software to make it work, removing their plausible deniability. However, isn't it possible that if builtins don't constitute linking, then open source proponents who oppose the GPL could simply write a BSD/MIT/Apache/Apple licensed product that links to a GPL'd program and claim that they intend to write a non-GPL interface that is identical to the GPL one, preserving their BSD license until it's actually compiled? [end aside] Sorry for the aside, I didn't think many people would follow why I care about this if I'm not facing any legal trouble or implications. Don't worry too much about the hypotheticals there, I'm just extrapolating what either answer to my actual question could imply.

Python namespace in between builtins and global?

- by Paul

Hello, As I understand it python has the following outermost namespaces: Builtin - This namespace is global across the entire interpreter and all scripts running within an interpreter instance. Globals - This namespace is global across a module, ie across a single file. I am looking for a namespace in between these two, where I can share a few variables declared within the main script to modules called by it. For example, script.py: import Log from Log import foo from foo log = Log() foo() foo.py: def foo(): log.Log('test') # I want this to refer to the callers log object I want to be able to call script.py multiple times and in each case, expose the module level log object to the foo method. Any ideas if this is possible? It won't be too painful to pass down the log object, but I am working with a large chunk of code that has been ported from Javascript. I also understand that this places constraints on the caller of foo to expose its log object. Thanks, Paul

How is the 'is' keyword implemented in Python?

... the is keyword that can be used for equality in strings. >>> s = 'str' >>> s is 'str' True >>> s is 'st' False I tried both __is__() and __eq__() but they didn't work. >>> class MyString: ... def __init__(self): ... self.s = 'string' ... def __is__(self, s): ... return self.s == s ... >>> >>> >>> m = MyString() >>> m is 'ss' False >>> m is 'string' # <--- Expected to work False >>> >>> class MyString: ... def __init__(self): ... self.s = 'string' ... def __eq__(self, s): ... return self.s == s ... >>> >>> m = MyString() >>> m is 'ss' False >>> m is 'string' # <--- Expected to work, but again failed False >>> Thanks for your help!

Are the atomic builtins provided by gcc actually translated into the example code, or is that just f

- by Jared P

So I was reading http://gcc.gnu.org/onlinedocs/gcc-4.1.0/gcc/Atomic-Builtins.html, and came across this: type __sync_and_and_fetch (type *ptr, type value, ...) type __sync_xor_and_fetch (type *ptr, type value, ...) type __sync_nand_and_fetch (type *ptr, type value, ...) These builtins perform the operation suggested by the name, and return the new value. That is, { *ptr op= value; return *ptr; } { *ptr = ~*ptr & value; return *ptr; } // nand Is this code literal? or is it just to explain what gcc is doing atomically using c-like syntax? And if this is the direct translation, can someone explain how it is atomic?

python: strange behavior about exec statement

- by ifocus

exec statement: exec code [ in globals[, locals]] When I execute the following code in python, the result really confused me. Some of the variables were setup into the globals, some were setup into the locals. s = """ # test var define int_v1 = 1 list_v1 = [1, 2, 3] dict_v1 = {1: 'hello', 2:'world', 3:'!'} # test built-in function list_v2 = [float(x) for x in list_v1] len_list_v1 = len(list_v1) # test function define def func(): global g_var, list_v1, dict_v1 print 'access var in globals:' print g_var print 'access var in locals:' for x in list_v1: print dict_v1[x] """ g = {'__builtins__': __builtins__, 'g_var': 'global'} l = {} exec s in g, l print 'globals:', g print 'locals:', l exec 'func()' in g, l the result in python2.6.5: globals: {'__builtins__': <module '__builtin__' (built-in)>, 'dict_v1': {1: 'hello', 2: 'world', 3: '!'}, 'g_var': 'global', 'list_v1': [1, 2, 3]} locals: {'int_v1': 1, 'func': <function func at 0x00ACA270>, 'x': 3, 'len_list_v1': 3, 'list_v2': [1.0, 2.0, 3.0]} access var in globals: global access var in locals: hello world ! And if I want to setup all variables and functions into the locals, and keep the rights of accessing the globals. How to do ?

Lost all privileges since upgrading to 13.10

Since upgrading to 13.10, I no longer have the 'privileges' to do the following things: Mount USB/CDROM drives Run software centre or software updater Press the GUI shut down or restart buttons Unlock my account in the 'settings - user accounts' section (padlock is greyed out) Also, when logging on as a guest user I get error messages relating to Compiz crashing with SIGSEGV and it hangs on a blank wallpaper screen.

Accessing Python module fails although its package is imported

- by codethief

Hey Stackers! :) My Django project's directory hierarchy looks like this: + pybsd |---+ devices |---+ templates |---+ views |---+ interaction |---- __init__.py |---- geraete.py |---- geraetemodelle.py |---- geraetegruppen.py |---- __init__.py |---- ajax.py |---- html.py |---- misc.py |---- __init__.py |---- urls.py |---- __init__.py |---- urls.py (Please excuse the German names. I preferred not to replace them here since it would add yet another possible error source when trying out the solutions you'll hopefully suggest and answering your questions.) Every request to http://URL/devices/.* is dispatched to the urls.py file living in /devices: # ... from views import html, ajax, misc, interaction urlpatterns = patterns('', # ... (r'^ajax/update/(?P<table>[a-z_]+)$', ajax.update), (r'^ajax/delete/(?P<table>[a-z_]+)$', ajax.delete), (r'^ajax/select_options/(?P<table>[a-z_]+)$', ajax.select_options), (r'^interaction/geraete/info/(?P<geraet>\d+)$', interaction.geraete.info), (r'^interaction/geraete/delete/(?P<geraet>\d+)?$', interaction.geraete.delete), (r'^interaction/geraetemodelle/delete/(?P<geraetemodell>\d+)?$', interaction.geraetemodelle.delete), (r'^interaction/geraetegruppen/delete/(?P<geraetegruppe>\d+)?$', interaction.geraetegruppen.delete), # ... ) All URL definitions work except for those referencing the interaction package. I'm constantly getting the following error: File "/home/simon/projekte/pybsd/../pybsd/devices/urls.py", line 33, in `<module>` (r'^interaction/geraete/info/(?P<geraet>\d+)$', interaction.geraete.info), AttributeError: 'module' object has no attribute 'geraete' I double-checked that the __init__.py files don't contain anything. Maybe you've already found the (Python- or Django-related?) mistake I made and am apparently unable to see. If not, read on. In any case, thanks for reading this long post! Isolating the problem 1st test It works if I provide the view functions as strings: (r'^interaction/geraete/info/(?P<geraet>\d+)$', 'devices.views.interaction.geraete.info'), (r'^interaction/geraete/delete/(?P<geraet>\d+)?$', 'devices.views.interaction.geraete.delete'), (r'^interaction/geraetemodelle/delete/(?P<geraetemodell>\d+)?$', 'devices.views.interaction.geraetemodelle.delete'), (r'^interaction/geraetegruppen/delete/(?P<geraetegruppe>\d+)?$', 'devices.views.interaction.geraetegruppen.delete'), ... or add yet another line to the imports: from views.interaction import geraete, geraetemodelle, geraetegruppen Using from views.interaction import *, however, doesn't work either and results in the same error message. 2nd test I created a file test.py in /devices: from views import interaction print dir(interaction) Output: simon@bsd-simon:~/projekte/pybsd/devices$ python test.py ['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__'] Again, no sign of the modules I created in the interaction package (geraete.py, geraetemodelle.py, geraetegruppen.py). Unlike in urls.py, trying from view.interaction import geraete, geraetegruppen, geraetemodelle in test.py results in ImportError: No module named view.interaction this time. 3rd test I started the Django shell: $ python manage.py shell >>> import devices.views.interaction.geraete >>> dir(devices.views.interaction.geraete) ['Abteilung', 'Auftrag', 'Auftragsvorlage', 'Geraet', 'Geraetegruppe', 'Geraetemodell', 'HttpResponse', 'HttpResponseBadRequest', 'HttpResponseRedirect', 'Raum', 'Standort', '__builtins__', '__doc__', '__file__', '__name__', '__package__', 'delete', 'info', 'models', 'move', 'render_to_response'] >>> $ python manage.py shell >>> from devices.views.interaction import geraete >>> dir(geraete) ['Abteilung', 'Auftrag', 'Auftragsvorlage', 'Geraet', 'Geraetegruppe', 'Geraetemodell', 'HttpResponse', 'HttpResponseBadRequest', 'HttpResponseRedirect', 'Raum', 'Standort', '__builtins__', '__doc__', '__file__', '__name__', '__package__', 'delete', 'info', 'models', 'move', 'render_to_response'] >>> $ python manage.py shell >>> import devices.views.interaction >>> devices.views.interaction.geraete Traceback (most recent call last): File "<console>", line 1, in <module> AttributeError: 'module' object has no attribute 'geraete' >>> dir(devices.views.interaction) ['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__']

http request to cgi python script successful, but the script doesn't seem to run

I have configured cgi scripts for my apache2 web server. Here is what I want to do: Client uploads the image to the server. (this already works) On success, I want to execute the python script to resize the image. I tried the following and the success function does execute but my python script does not seem to execute: Javascript code that sends the request: var input = document.getElementById('imageLoader'); imageName = input.value; var file = input.files[0]; if(file != undefined){ formData= new FormData(); console.log(formData.length); if(!!file.type.match(/image.*/)){ formData.append("image", file); $.ajax({ url: "upload.php", type: "POST", processData: false, contentType: false, success: function() { var input = document.getElementById('imageLoader'); imageName = input.value; var file = input.files[0]; formData = new FormData(); formData.append("filename", file); $.ajax({ url: "http://localhost/Main/cgi-bin/resize.py", type: "POST", data: formData, processData: false, contentType: false, success: function(data) { console.log(data); } }); // code continues... resize.py: #!/usr/bin/python import cgi import cgitb import Image cgitb.enable() data = cgi.FieldStorage() filename = data.getvalue("filename") im = Image.open("../JS/upload/" + filename) (width, height) = im.size maxWidth = 600 maxHeight = 400 if width > maxWidth: d = float(width) / maxWidth height = int(height / d) width = maxWidth if height > maxHeight: d = float(height) / maxHeight width = int(width / d) height = maxHeight size = (width, height) im = im.resize(size, Image.ANTIALIAS) im.save("../JS/upload/" + filename, quality=100) This is the apache2.conf: <Directory /var/www/html/Main/cgi-bin> AllowOverride None Options +ExecCGI SetHandler cgi-script AddHandler cgi-script .py .cgi Order allow,deny Allow from all </Directory> cgi-bin and python script file permissions: drwxrwxr-x 2 mou mou 4096 Aug 24 03:28 cgi-bin -rwxrwxrwx 1 mou mou 1673 Aug 24 03:28 resize.py Edit: Executing this code $.ajax({ url: "http://localhost/Main/cgi-bin/resize.py", type: "POST", data: formData, // formData = {"filename" : "the filename which was saved in a variable whie the image was uploaded"} processData: false, contentType: false, success: function(data) { alert(data); } }); it alerts the following: <body bgcolor="#f0f0f8"><font color="#f0f0f8" size="-5"> --> <body bgcolor="#f0f0f8"><font color="#f0f0f8" size="-5"> --> --> </font> </font> </font> </script> </object> </blockquote> </pre> </table> </table> </table> </table> </table> </font> </font> </font><body bgcolor="#f0f0f8"> <table width="100%" cellspacing=0 cellpadding=2 border=0 summary="heading"> <tr bgcolor="#6622aa"> <td valign=bottom> <br> <font color="#ffffff" face="helvetica, arial"> <br><big><big><strong><type 'exceptions.TypeError'></strong></big></big></font></td ><td align=right valign=bottom ><font color="#ffffff" face="helvetica, arial">Python 2.7.6: /usr/bin/python<br>Sun Aug 24 17:24:15 2014</font></td></tr></table> <p>A problem occurred in a Python script.

MySQL died during the night on a 12.04.1 Ubuntu

- by Olivier

I can't explain why, but somehow during the night, one of my MySQL running on an Ubuntu 12.04.1 box broke. The service is running but I can't login anymore (to SQL), the previous password is not working anymore. It does not looks like the server has been compromised (nothing in /var/auth.log) It looks like some automatic security upgrade (server is configured to perform those) has occured and broke something. The MySQL server has restarted a couple of times in the logs at the time errors started to happen (I get email when CRON task fail). In the logs it complains about an unset root password (I do have cron job running all day using SQL so the password was set & working for months). Anyway I can't login without password either!

Using cd to go up multiple directory levels

- by Tossrock

I'm dealing with java projects which often result in deeply nested folders (/path/to/project/com/java/lang/whatever, etc) and sometimes want to be able to jump, say, 4 directory levels upwards. Typing cd ../../../.. is a pain, and I don't want to symlink. Is there some flag to cd that lets you go up multiple directory levels (in my head, it would be something like cd -u 4)? Unfortunately I can't find any man page for cd specifically, instead just getting the useless "builtins" page.

vim how to comma align

- by anon

I have a bunch of code of the form: someVector.push_back(Foo("some name", 1.0, 3.1415926); someVector.push_back(Foo("different length name", 89.0, 2.717); ... 20 more entries I want sufficient space to be inserted so that my code is comma aligned, i.e. the "1.0," 's comma and the "89.0"'s comma are aligned -- is there builtins to do this?

gcc compiling error on Solaris 10

- by osman toker

I want to compile a source code, but there are some compiling errors about __sync_xxx functions (__sync_bool_compare_and_swap etc.) GCC version on machine is 3.4.3 (it must be gcc 4.1 or over for supporting atomic builtins), so I have downloaded GCC v4.6, copied it to another directory (I didn't remove v3.4.3) then change the $PATH path for GCC but it doesn't work (the same error occurs). I want to ask that is only changing gcc path with export PATH=... enough for compiling with new GCC?

effective functional sort

I'm programming a function for a TI-NSpire, so I can't use the builtins from inside a function. What is the most generally efficient algorithm for sorting a list of numbers without modifying the list itself? (recursion and list-splitting are fair game, as is general use of math.)

- by ted

Sorry for my English; I was trying to create db with rake in RoR application that has been configured for MySQL(gem installed, settings changed). After that attempt mysql-server broke: d@calister:~$ mysql ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) mysqld is not running at all: d@calister:~$ ps aux | grep mysql d 3769 0.0 0.0 4368 832 pts/0 S+ 18:03 0:00 grep --color=auto mysql And also it doesn't seem it would like to run: d@calister:~$ sudo service mysql start start: Job failed to start Any suggestions?

Usabe of Python 3 super()

- by deamon

I wonder when to use what flavour of Python 3 super(). Help on class super in module builtins: class super(object) | super() -> same as super(__class__, <first argument>) | super(type) -> unbound super object | super(type, obj) -> bound super object; requires isinstance(obj, type) | super(type, type2) -> bound super object; requires issubclass(type2, type) Until now I've used super() only without arguments and it worked as expected (by a Java developer). Questions: What does "bound" mean in this context? What is the difference between bound and unbound super object? When to use super(type, obj) and when super(type, type2)? Would it be better to name the super class like in Mother.__init__(...)?

django 'if' statement improperly formatted

- by Zayatzz

Im getting strangest error in django so far: 'if' statement improperly formatted Template that raises the error is this: {% if diff >= 0 %} <span class="pos">+{{ diff }} {% else %} <span class="neg">-{{ diff }} {% endif %} </span> <span>{{ a }}</span> view that has a and diff in context is this: def add(request, kaart_id): if request.is_ajax() and request.method == 'POST': x = Kaart.objects.get(id=kaart_id) x.pos += 1 x.save x = Kaart.objects.get(id=kaart_id) from django.utils import simplejson diff = x.pos - x.neg a = "(+1)" context = { 'diff':diff, 'a':a } return render_to_response('sum.html', context, context_instance=RequestContext(request)) It does not matter what equation i use in if, , =, ==.. they all raise the same error. and as far as i can tell its all by the book: http://docs.djangoproject.com/en/dev/ref/templates/builtins/#id5 Alan.
