• Ruby: rules for implicit hashes

  - by flyer

  Why second output shows me only one element of Array? Is it still Array or Hash already? def printArray(arr) arr.each { | j | k, v = j.first printf("%s %s %s \n", k, v, j) } end print "Array 1\n" printArray( [ {kk: { 'k1' => 'v1' }}, {kk: { 'k2' => 'v2' }}, {kk: { 'k3' => 'v3' }}, ]) print "Array 2\n" printArray( [ kk: { 'k1' => 'v1' }, kk: { 'k2' => 'v2' }, kk: { 'k3' => 'v3' }, ]) exit # Output: # # Array 1 # kk {"k1"=>"v1"} {:kk=>{"k1"=>"v1"}} # kk {"k2"=>"v2"} {:kk=>{"k2"=>"v2"}} # kk {"k3"=>"v3"} {:kk=>{"k3"=>"v3"}} # Array 2 # kk {"k3"=>"v3"} {:kk=>{"k3"=>"v3"}}

• Problem with accessing in DOM with jQuery

  - by Tristan

  Hello, I changed the tree of my JSON-P output, and i cannot access to my object DOM anymore : Here's my output : jsonp1271634374310( {"Inter-Medias": {"name":"Inter-Medias","idGSP":"14","average":"80","services":"8.86"} }); And here's my jQuery script : success: function(data, textStatus, XMLHttpRequest){ widget = data.name; widget += data.average ; .... I know one level is missing, but if I try to do : data.Inter-Medias.name or data.name.name it's still not working. Any idea please ? I will have case where i'll have multiple Ojbect, so i want to display all of them, how to do that ? for (i=0;i < data.length;i++) Does it look right ? Bonus question : i understand function(data, textStatus, XMLHttpRequest) that in case of success this function is triggered, the data is what the script recieved from his request, but i have no idea what textStatus or XMLHttpRequest are here too and why ?! Thank you.

• Python 3-compatibe HTML to text converter preserving basic structure under permissive licence?

  - by hawk64

  I am looking for a relatively simple HTML to text converter which displays links and works on strings. So far I have tried lynx but performance is too bad, html2text which gives weird and verbose markdown output and is under GPLv3 which is too restrictive for my (BSD-licensed) project, http://effbot.org/librarybook/formatter-example-3.py using htmllib.HTMLParser with formatter.AbstractFormatter and a custom writer, however htmllib.HTMLParser is drpeceated and has been removed from Python 3. So is there any simple, performant, Python 3-compatible HTML to text converter under a permissive license such as MIT/BSD/Apache and the like? Edit: I dont just need something to strip HTML-Tags but also to preserve the basic structure of the HTML, that is output that somewhat resembles that of Lynx.

• Listing and deleting Git commits that are under no branch (dangling?)

  - by Samer Abukhait

  I've got a git repository with plenty of commits that are under no particular branch, I can git show them but when I try to list branches that contain them, it reports back nothing: I thought this is the dangling commits/tree issue (as a result of -D branch), so I pruned the repo, but I still see the case after that: $ git fetch origin $ git fsck --unreachable $ git fsck No output, nothing dangling (right?) $ git show 793db7f272ba4bbdd1e32f14410a52a412667042 commit 793db7f272ba4bbdd1e32f14410a52a412667042 Author: .. But $ git branch --contains 793db7f272ba4bbdd1e32f14410a52a412667042 Gives no output What exactly is the state of that commit? How can I list all commits with similar state, How can I delete commits like those?

• Setting precision on std::cout in entire file scope - C++ iomanip

  - by Ivan

  Hi all, I'm doing some calculations, and the results are being save in a file. I have to output very precise results, near the precision of the double variable, and I'm using the iomanip setprecision(int) for that. The problem is that I have to put the setprecision everywhere in the output, like that: func1() { cout<<setprecision(12)<<value; cout<<setprecision(10)<<value2; } func2() { cout<<setprecision(17)<<value4; cout<<setprecision(3)<<value42; } And that is very cumbersome. Is there a way to set more generally the cout fixed modifier? Thanks

• Streaming data to the browser as a file of unknown size

  - by Sir Psycho

  I have some data which is queried from the database and I'd like to send it to the client as a csv file. The file size varies each time due to the fact that the DB data returned can be of any size. Instead of saving this file to the hard disk, I'd like to send it to the browser at the same time it's being processed into a CSV by my algorithm. Response.Write seems useless. For some reason, the file download dialog is only displayed once my processing is finished. This seems odd as I'm writting all my output to the Response.Output stream. I have downloaded files on the web before where the filesize is not known and the browser just keeps on downloading. Is there any way to achieve this? The following stackoverflow thread did not offer any good advise. http://stackoverflow.com/questions/873995/asp-net-downloading-large-files-of-unknown-size Thanks

• c++ polymorphism and other function question

  - by aharont

  i have got this code: class father{ public: virtual void f() { cout<<1;} }; class son:public father{ public: void f() {cout<<2;} }; void test (father x){x.f();} int main(){ son s; test(s); } the question says: the output is '1', what is the rule about polymorphism that the programmer forgot and how can i fix it so the output would be '2'? there is another rule that the programmer forgot when he wrote the father class, and he need to add an empty function to avoid problems from other sons of the father class. what is the rule and what is the missing function? another question write the g function so the next code would run with no crashes int x=11; g(x)=22;

• Returning multiple datasets from a stored proc in VB

  - by Ryan Stephens

  I have an encrypted SQL Server stored proc that I run with (or the vb .net equivalent code of): declare @p4 nvarchar(100) set @p4=NULL declare @p5 bigint set @p5=NULL exec AA_PAY_BACS_EXPORT_RETRIEVE_S @PS_UserId=N'ADMN', @PS_Department=N'', @PS_PayFrequency=2, @PS_ErrorDescription=@p4 output select @p4, @p5 this returns 2 datasets and the output parameters for the results, the datasets are made up of various table joins etc, one holds the header record and one the detail records. I need to get the 2 datasets into a structure in VB .net (e.g. linq, sqldatareader, typed datasets) so that I can code with them, I don't know what tables any of this comes from and there are alot of them Whooopeee!!! I came close using Linq to SQL and IMultipleResults but got frustrated when I had to recode it every time I made a change to the designer file. My feelings are that there must be a simple way to do this, any ideas?

• android accelerometer accuracy is extremely poor

  Wrote a simple program that prints out accelerometer output. mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE); mSensorManager.registerListener(this,mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_FASTEST); It turns out that: The accelerometer output is always set to "lowest" as determined by: public void onAccuracyChanged(Sensor sensor, int accuracy) { if (collectingData){ accelPrecision.setText("accelerometer accuracy: " + accuracy); } } The actual accelerometer readings are very inaccurate - about 2%-5% fluctuations even when it's resting on the table as far as I can tell it's the same problem on Nexus S, Nexus One and G1 Any idea how it could be made mode accurate / what sets a

• Django: Data corrupted after loading? (possible programmer error)

  I may be loading data the wrong way. excerpt of data.json: { "pk": "1", "model": "myapp.Course", "fields": { "name": "Introduction to Web Design", "requiredFor": [9], "offeringSchool": 1, "pre_reqs": [], "offeredIn": [1, 5, 9] } }, I run python manage.py loaddata -v2 data: Installed 36 object(s) from 1 fixture(s) Then, I go to check the above object using the Django shell: >>> info = Course.objects.filter(id=1) >>> info.get().pre_reqs.all() [<Course: Intermediate Web Programming>] # WRONG! There should be no pre-reqs >>> from django.core import serializers >>> serializers.serialize("json", info) '[{"pk": 1, "model": "Apollo.course", "fields": {"pre_reqs": [11], "offeredIn": [1, 5, 9], "offeringSchool": 1, "name": "Introduction to Web Design", "requiredFor": [9]}}]' The serialized output of the model is not the same as the input that was given to loaddata. The output has a non-empty pre_req list, whereas the input's pre_reqs field is empty. What am I doing wrong?

• What happens to a SIGINT (^C) when sent to a perl script containing children?

  - by CmdrGuard

  I have a Perl script that forks. Each fork runs an external program, parses the output, and converts the output to a Storable file. The Storable files are then read in by the parent and the total data from each of the children are analyzed before proceeding onto a repeat of the previous fork or else the parent stops. What exactly happens when I issue a ^C while some of the children are still running the external program? The parent perl script was called in the foreground and, I presume, remained in the foreground despite the forking. Is the SIGINT passed to all children, that is, the parent, the parent's children, and the external program called by the children??

• Calling Tortoise from command line and build if new code (how to know if tortoise updated anything)?

  - by Iakob

  I am writing a batch file which is supposed to update the source files from tortoise and - if anything new was gotten - build the solution. Should be a very simple task. My batchfile looks like this (I've removed the non-essentials) set updatepath=%1 set solution=%2 set output=%3.txt call TortoiseProc.exe /command:update /path:%updatepath% /closeonend:2 call %devenv% %solution% /Build Debug /Out %output% Now, I'd like to know if tortoise actually got new code for me and the not build if it didn't. How do I do this? I am running Windows Vista (The batch script is called from another batch script about 7 times - one for each project I need updated and - perhaps - build).

• Can somehow show progress on file upload without using AJAX?

  - by nimo

  Let's say that I upload a file using a basic multipart post. The server then receives the request and starts to execute the server side code. Can I somehow in that state start to output the response and after some data is sent start to receive the file? Finally when the file is uploaded I output the rest of the response. If this is possible I can display file upload progress without using ajax? I guess this might depend on what I run server side. But let's assume that I have full network control.

• Django admin proper urls inside listview

  - by hinnye

  Hi, My current target is to give users the chance to download CSV files from the admin site of my application. I successfully managed to create an additional column in the model's list view this way: def doc_link(self): return '<a href="files/%s">%s</a>' % (self.output, self.output) doc_link.allow_tags = True This shows the file name and creates the link, but sadly - because it's inside my 'searches' view - it has an URL: my_site/my_app/searches/files/13.csv. This is my problem, I would like to have my files stored in the admin media directory, like this: http://my_site/media/files/13.csv Does somebody know how to give url which points "outer" from the model's directory? Maybe somehow tell Django to use the ADMIN_MEDIA_PREFIX in the link? I'd really appreciate any help, thanks!

  Hi I have a C++ console Exe which does some progamming. Now i wanted to write a C# GUI which does some of the programming that the C++ exe does. I was thinking of few approaches, Write the C# GUI with all programming in C++ done from scratch.(I do not want to do this for the amount of rework it entails) Build a C++ dll which does the programming and have it imported in GUI app.(Now here i have a concern. How do i capture the output of the routines in c++ dll and display it in GUI? Should i return the output as string for every routine that the app calls.? Since i dont know managed c++ iam going to build an unmanaged C++ dll. )
