• How to efficiently track my geolocation during traveling using iPhone

  - by Peter Kruithof

  I'm going to travel through Thailand and I want to keep track of my location to geotag photos afterwards taken with a digital camera (iPhone's camera is not good enough). There are two things that are important here: I don't want to update manually I want the battery to last as long as possible, since the times I will be able to charge will be scarce I've thought about creating a web page that periodically sends my geolocation to a script that stores it in a database, but I don't know if GPS data is available in Mobile Safari. Second, I want the data I send to be as small as possible, and the frequency this is done s few as possible, because of the pricing of mobile data usage abroad. Any suggestions what would be a good solution here?

• SVN Delete with wildcard?

  - by David Lively

  I'm migrating a VSS repository to SVN and inadvertently included all of the _vti_cnf, *.scc files in the first check-in. I'd like to remove these from SVN. (Not permanently, of course - just in the HEAD). The application in question is quite large, and finding and deleting these files on a folder-by-folder basis will take forever. Suggestions? There must be some obvious way to do this, but the proximity of the weekend is interfering with my higher brain functions.

• How to create simple animations in 3gp format?

  - by yaseemin

  I am trying to create a simple animation which includes face of a famous character. For example Santa Clause. The face and the lips of the character will act according to the given input message. For example if a string is inputed then the lips of the character will be opened and closed till the end of the string while the given input message is vocalized using a text to speech converter. Moreover if the " :) " is used the character in the animation will smile. How could I do this? I was told that I can create this type of animations using "smill". But this is not convenient for the other purposes therefore I need to use a different method. Could you give me any suggestions? Thanks in advence.

• bash tips needed for understanding how to escape characters in command-line

  - by Jesper Rønn-Jensen

  My knowledge of commandline bash is missing on a particular area: I constantly forget how to properly escape characters. Today I wanted to echo this string into a file: #!/bin/env bash python -m SimpleHTTPServer echo "#!/bin/env bash\npython -m SimpleHTTPServer" server.sh && chmod +x server.sh -bash: !/bin/env: event not found That's right: Remember to escape ! or bash will think it's a special bash event command. But I can't get the escaping right! \! yields \! in the echoed string, and so does \\!. Furthermore, \n will not translate to a line break. Do you have some general tips that makes it easier for me to understand escaping rules? To be very precise, I'll accept an answer which tells me which characters I should escape on the bash command line? Including how to correctly output newline and exclamation mark in my example.

• Rake don't know how to build task?

  - by Schroedinger

  Using a rake task to import data into a database: file as follows namespace :db do desc "load imported data from csv" task :load_csv_data => :environment do require 'fastercsv' require 'chronic' FasterCSV.foreach("input.csv", :headers => true) do |row| Trade.create( :name => row[0], :type => row[4], :price => row[6].to_f, :volume => row[7].to_i, :bidprice => row[10].to_f, :bidsize => row[11].to_i, :askprice => row[14].to_f, :asksize => row[15].to_i ) end end end When attempting to use this, with the right CSV files and the other elements in place, it will say Don't know how to build task 'db:import_csv_data' I know this structure works because I've tested it, I'm just trying to get it to convert to the new values on the fly. Suggestions?

• Match regex from right to left?

  - by Balroq

  Hi! Is there any way of matching a regex from right to left? What Im looking for is a regex that gets MODULE WAS INSERTED EVENT LOST SIGNAL ON E1/T1 LINK OFF CRC ERROR EVENT CLK IS DIFF FROM MASTER CLK SRC OF from this input CLI MUX trap received: (022) CL-B MCL-2ETH MODULE WAS INSERTED EVENT 07-05-2010 12:08:40 CLI MUX trap received: (090) IO-2 ML-1E1 EX1 LOST SIGNAL ON E1/T1 LINK OFF 04-06-2010 09:58:58 CLI MUX trap received: (094) IO-2 ML-1E1 EX1 CRC ERROR EVENT 04-06-2010 09:58:59 CLI MUX trap received: (009) CLK IS DIFF FROM MASTER CLK SRC OFF 07-05-2010 12:07:32 If i could have done the matching from right to left I could have written something like everything to right of (EVENT|OFF) until the second appearance of more than one space [ ]+ The best I managed today is to get everything from (022) to EVENT with the regex CLI MUX trap received: \([0-9]+\)[ ]+(.*[ ]+(EVENT|OFF)) But that is not really what I wanted :)

• How to change a grouped UITableView cell's background to black (or non-white)?

  - by Meltemi

  Just want to make sure I'm not overlooking something obvious... It seems like it should be trivial to set the background color (black is fine) of a UITableView's cell to something other than white or completely transparent so that you can display your data with white text. However, with my attempts I lose the corners on my grouped table view and it all looks like crap. I've seen & understand the methods described by Matt Gallagher about customizing TableView cells with exotic gradients, etc. but wanted to be certain before heading down that path...

• store/load numpy array from binary files

  - by Javier

  Dear all, I would like to store and load numpy arrays from binary files. For that purposes, I created two small functions. Each binary file should contain the dimensionality of the given matrix. def saveArrayToFile(data, fileName): with open(fileName, 'w') as file: a = array.array('f') nSamples, ndim = data.shape a.extend([nSamples, ndim]) # write number of elements and dimensions a.fromstring(data.tostring()) a.tofile(file) def readArrayFromFile(fileName): _featDesc = np.fromfile(fileName, 'f') _ndesc = int(_featDesc[0]) _ndim = int(_featDesc[1]) _featDesc = _featDesc[2:] _featDesc = _featDesc.reshape([_ndesc, _ndim]) return _featDesc, _ndesc, _ndim An example on how to use the functions is: myarr=np.array([[7, 4],[3, 9],[1, 3]]) saveArrayToFile(myarr,'myfile.txt') _featDesc, _ndesc, _ndim = readArrayFromFile('myfile.txt') However, an error message of 'ValueError: total size of new array must be unchanged' is shown. My arrays can be of size MxN and MxM. Any suggestions are more than welcomed. I think the problem might be in the saveArrayToFile function. Best wishes, Javier

• A good design pattern for almost similar objects

  - by Sam

  Hello, I have two websites that have an almost identical database schema. the only difference is that some tables in one website have 1 or 2 extra fields that the other and vice versa. I wanted to the same Database Access layer classes to will manipulate both websites. What can be a good design pattern that can be used to handle that little difference. for example, I have a method createAccount(Account account) in my DAO class but the implementation will be slightly different between website A and website B. I know design patterns don't depend on the language but FYI i m working with Perl. Thanks

• Creating a process in a non-zero session from a service in windows-2008-server?

  - by Itay Levin

  Hi, I was wondering if there is a simple way for a service to create a process in user session? My service is running as a user(administrator) account and not as a LocalSystem acount, therefore i can't use the WTSQueryUserToken function. i have tried calling OpenProcessToken(GetCurrentProcess,TOKEN_ALL_ACCESS,TokenHandle); but when i use this token to run CreateProcessAsUser(TokenHandle,.....) my process is still running in session 0. how can i resolve this issue? I'm using an Ole automation so i don't really care on which session the process will be running on, as long it is not the session 0 - because the Ole from some reason doesn't create its processes (winword.exe for instance) in session 0, but rather it creates them in other user sessions. Any suggestions will be welcome. Thanks in advance.

• IE HTTPS Ajax request image not showing up

  - by Sha Le

  Hi: In IE (7 or 8) and HTTPS mode, following RESPONSE is delivered for an AJAX request. My issue is the img was NOT requested at all by IE (figured out using Fiddler), broken img is shown instead. It all works perfectly in HTTP mode in IE and other browsers no problem rendering in both mode (please don't tell me not to use IE). Any thoughts/work-arounds/suggestions?

• Loop through text nodes inside a div

  - by crosenblum

  I am trying to do a text replace, but to do so, i need to loop through the text nodes of a div. Each Div upon clicking, loads via ajax it's appropriate content. But then I need to do text-replacing inside any of the text nodes inside there. My current code, after loading the ajax content, loops through all text nodes of the whole page, and therefore is too resource intensive. I have been looking for hours trying to find out how to both loop thru a div, and get the text nodes... and this has to work in firefox, google chrome and ie6. Any thoughts or suggestions?

• object won't die (still references to it that I can't find)

  - by user288558

  I'm using parallel-python and start a new job server in a function. after the functions ends it still exists even though I didn't return it out of the function (I used weakref to test this). I guess there's still some references to this object somewhere. My two theories: It starts threads and it logs to root logger. My questions: can I somehow findout in which namespace there is still a reference to this object. I have the weakref reference. Does anyone know how to detach a logger? What other debug suggestions do people have? here is my testcode: def pptester(): js=pp.Server(ppservers=nodes) js.set_ncpus(0) fh=file('tmp.tmp.tmp','w') tmp=[] for i in range(200): tmp.append(js.submit(ppworktest,(),(),('os','subprocess'))) js.print_stats() return weakref.ref(js) thanks in advance Wolfgang

• PHP gallery, thumbnail listing

  - by Benjamin

  Hi everyone, I am planning a dynamic PHP photo gallery and having difficulty deciding on the best way to display the thumbnails after they have been retrieved via MySQL. I considered using an inline unordered list but this resulted in the thumbs being stacked one on top of the other (touching). Also tried a table but not sure how I would start the next row after x number of thumbnails. Any suggestions on page layout for this purpose? I will be using Lightbox to cycle through the photos themselves, that isn't the issue. Also, would a while() loop be best for fetching the list of thumbs and inserting the appropriate HTML? Thanks! -Ben

• MS CRM - getting the field that caused a form save

  - by CraigF

  I have a MS CRM 4 form where when certain fields are changed, I need those fields to be written to an excel sheet. So, I edited the form field onchange event to call crmform.save() which triggers a plugin to run that writes the field value to a named range (1 cell) of an excel sheet. However, I don't know which field caused the save. Is there a way to get that information? (Not all fields on the form need to go to the excel sheet) If I use this: DynamicEntity target = (DynamicEntity)Context.InputParameters[ParameterName.Target]; I can look at specific fields, but I have no way of knowing which ones changed. Any suggestions?

• A JTAG emulator for use with a Hawkboard and OpenOCD?

  - by David Brown

  I'd like to try bare metal ARM programming with the Hawkboard, but the deployment process looks awful. I'm totally new to this, so I could be misunderstanding the instructions, but it appears that I have to use a program called AISgen to convert the binary file, then boot with u-Boot over UART and copy the AIS binary into memory. Not only is that a lot of stuff to do every time I make a change, it also doesn't give me the ability to debug with GDB. The best solution for this that I can find is JTAG. But the prices for these JTAG emulators look ridiculous. I'm not even sure which ones will work with the Hawkboard and which ones won't. So far, my best bet appears to be the Flyswatter, but the pin layout is different. Basically, I need something that's relatively cheap and works with the Hawkboard and OpenOCD. Any suggestions? Or is there another way I could do this, perhaps?

• Multiple .obj Models in THREE.js and detecting clicked objects

  - by ZedBee

  I have been following along this example to load .obj Model using three.js. Since I needed more than one model to load so I tried this loader.addEventListener( 'load', function ( event ) { var object = event.content; object.position.y = - 80; scene.add( object ); }); loader.load( 'obj/model1.obj' ); loader.load( 'obj/model2.obj' ); First: I don't know whether this is the right approach or not since I searched but didn't find any tutorial loading more than one .obj models. Second: I want to be able to click different models on the screen. I tried this which doest not seem to work for me. Any suggestions on this?

• Creating colour schemes based on an existing scheme

  - by Neil Barnwell

  I have a colour scheme based around yellow, for warning messages on a website. It amounts to a slightly orange bordered box, with a pale yellow fill. The exact colours are: #FED626 (border) #FFF7C0 (fill) I want to know if it's possible to convert this scheme mathematically or algorithmically somehow, to come up with a blue version where the border is the "same amount" of blue as this one is yellow. Is this possible, or do I just "pin the tail on the donkey" on a colour pallet to get roughly the right one? I ask, because I'd quite like to be able to calculate this on the fly, to perhaps implement something in .less. To give you an idea, I tried swopping the red and blue values on those two, and came up with this: #26D6FE (border) #C0F7FF (fill) That wasn't too hard, but think about if I wanted a pink colour scheme... :)

• Will be self-taught limit me?

  - by Isaiah

  I'm 21 and am pretty efficient in html/css, python, and javascript. I also know my way around lisp languages and enjoy programing in them. My problem is that I'm extremely self-taught and not quite confident that I could land a job programing, but I really need a job soon as I've just become a father. I haven't even created a resume yet because I'm not really sure what to put on it except my lone experience. So I wanted to ask, will being primarily self-taught with some experience on small projects I've done for a few clients limit me too much? I mean I know I need some kind of education so I've enrolled part time in a community college to work on a degree in computer science, but it's years till then. And if it will limit me a lot, what kind of skills would be good to work on to make my chances any better? Thank You

• Change color on single-series line chart using rCharts and Highcharts?

  - by Sharon

  Is it possible to change the color of a line using rCharts and Highcharts so that the line color changes depending on a factor? I've done this with ggplot2 but would like to make an interactive version if possible. I've tried h1 <- Highcharts$new() h1$chart(type="line") h1$series(data=mydf$myvalue, name="", groups = c("myfactor")) h1$xAxis(tickInterval = 4, categories = mydf$myXaxis) but that's not working, line stays the same color. Sample data myvalue <- c(16, 18, 5, 14, 10) myXaxis <- c(1,2,3,4,5) myfactor <- c("old", "old", "old", "new", "new") mydf <- data.frame(myvalue, myXaxis, myfactor) Thanks for any suggestions.

• Has anyone combined soap.py or suds with python-ntlm?

  - by Chris R

  I'd like to replace an app's current (badly busted and crufty) cURL-based (cURL command-line based!) SOAP client with suds or soap.py. Trouble is, we have to contact an MS CRM service, and therefore must use NTLM. For a variety of reasons the NTLM proxy is a bit of a pain to use, so I'm looking into python-ntlm to provide that support. Can suds or soap.py be made to use this authentication method? If so, how? If not, any other suggestions would be fantastic.

• Openfire scalability question XMPP Server

  - by candoyo

  Hello! Do you guys know how well openfire scales? My users will be using the application to do normal chatting like msn no file transfer for now. We will be using Amazon's EC2 server to run the chat server we would like to support over 1 Million users in total and around 30-50K active users during peak times. Since clustering is now opensource, I though Openfire might be the way to go, how much will it cost for the coherence license or can I bipass that somehow? Also, I wanted to develop plugin for Openfire if we go with it. Any pointers on how to set up a dev env and get going would be helpful too! Thanks ya'all! :)

• PHP: How to use mysql fulltext search and handle fulltext search result

  - by garcon1986

  Hello, I have tried to use mysql fulltext search in my intranet. I wanted to use it to search in multiple tables, and get the independant results depending on tables in the result page. This is what i did for searching. $query = " SELECT * FROM testtable t1, testtable2 t2, testtable3 t3 WHERE match(t1.firstName, t1.lastName, t1.details) against(' ".$value."') or match(t2.others, t2.information, t2.details) against(' ".$value."') or match(t3.other, t2.info, t2.details) against(' ".$value."') "; $result = mysql_query($query)or die('query error'.mysql_error()); while($row = mysql_fetch_assoc($result)){ echo $row['firstName']; echo $row['lastName']; echo $row['details'].'<br />'; } Do you have any ideas about optimizing the query and format the output of search results?

• How to associate node with products in Drupal/Ubercart

  - by henrijs.seso

  I am looking for a way to allow users to add node reference to each product or whole cart @ checkout. I am making web site where users can buy items and then receive them on board flight. Products are fixed, but user needs to tell for which flight he is buying items. Flights are nodes and users has flagged these nodes so there is no problem making View with users flagged flight nodes. How would I associate one of these nodes with purchase? Nodereference from CCK would be cool, but checkout is probably not node. Any suggestions for approach?
