• How do I write raw binary data in Python?

  - by Chris B.

  I've got a Python program that stores and writes data to a file. The data is raw binary data, stored internally as str. I'm writing it out through a utf-8 codec. However, I get UnicodeDecodeError: 'charmap' codec can't decode byte 0x8d in position 25: character maps to <undefined> in the cp1252.py file. This looks to me like Python is trying to interpret the data using the default code page. But it doesn't have a default code page. That's why I'm using str, not unicode. I guess my questions are: How do I represent raw binary data in memory, in Python? When I'm writing raw binary data out through a codec, how do I encode/unencode it?

• Searching in Rails 3

  - by cbarton

  Here is the situation: I have the need to search for specifics or generals, much like expedia.com or your local library catalog search. In that there are fields that may or may not be filled out based on the individual need. It acts much like an "advanced search page". I have all of that code done for the models/controller and such and have it setup with a Searches controller along with matching model and views. The question that I have is there a way to cut down the amount of parameters posted to GET so that the url isn't search?search[:a]=""+search[:b]=""+search[:c]="x"... plus the unicode checkmark. I only want the filled out fields to be shown in the response link especially minus the checkmark. cbarton

• How do I indent multiple lines at once in Notepad++?

  - by cdeszaq

  In many text editors that are aimed at programmers, if the user has a selection that spans more than 1 line and presses the TAB key, those lines are indented by 1 TAB (or a number of spaces, depending on how the editor is configured). However, this does not seem to be the default behavior of Notepad++. Is there a way I can do this in Notepad++, or is there a plugin that I can get to allow me to do this? Edit: Upon additional testing, shift-tab correctly un-indents the lines as expected, but only a tab simply inserts a tab wherever the carat is. This is in version 5.4.5 Unicode

• Python BeautifulSoup Print Info in CSV

  - by Codin

  I can print the information I am pulling from a site with no problem. But when I try to place the street names in one column and the zipcodes into another column into a CSV file that is when I run into problems. All I get in the CSV is the two column names and every thing in its own column across the page. Here is my code. Also I am using Python 2.7.5 and Beautiful soup 4 from bs4 import BeautifulSoup import csv import urllib2 url="http://www.conakat.com/states/ohio/cities/defiance/road_maps/" page=urllib2.urlopen(url) soup = BeautifulSoup(page.read()) f = csv.writer(open("Defiance Steets1.csv", "w")) f.writerow(["Name", "ZipCodes"]) # Write column headers as the first line links = soup.find_all(['i','a']) for link in links: names = link.contents[0] print unicode(names) f.writerow(names)

• Reading bytes from JavaScript string

  - by Jan

  I have a string containing binary data in JS. Now I want to read, for example, an integer from it. So I get the first 4 characters, use charCodeAt, do some shifting etc. to get an integer. Problem is that strings in JS are UTF-16 (instead of ASCII) and charCodeAt often returns values higher than 256. The Mozilla reference states that "The first 128 Unicode code points are a direct match of the ASCII character encoding." (what about ASCII values 128?) How can I convert the result of charCodeAt to an ASCII value? Or is there a better way to convert a string of four characters to a 4 byte integer?

• Velocity templates seem to fail with UTF-8

  - by steve

  Hi, i have been trying to use a velocity Template with the following content: Sübjäct $item everything works fine except the translation of the tow unicode characters. The result string printed on the commandline looks like: Sübjäct foo I searched the velocity website and the web an this issue, and came uo with differnt font encoding options, which i added to my code. But those won't help. This is the actuall code: velocity.setProperty("file.resource.loader.path", absPath); velocity.setProperty("input.encoding", "UTF-8"); velocity.setProperty("output.encoding", "UTF-8"); Template t = velocity.getTemplate("subject.vm"); t.setEncoding("UTF-8"); StringWriter sw = new StringWriter(); t.merge(null, sw); System.out.println(sw.getBuffer()); Can anyone give me some hints, how to fix this issue?

• Why isn't my javascript working on a local HTML file using UIWebView loadRequest:?

  - by Raphael

  Hi Everyone, I have a script that generates a temporary HTML file that has links to external Javascript files that it requires to run. <script src="file:///Users/raphaeldefranco/Library/Application Support/iPhone Simulator/User/Applications/BA9E724E-76BD-4F28-B224-54B4C73786D6/LogTen.app/Reports/Time by Year/../../Tools/PlotKit/Base.js" type="text/javascript"></script> The links are absolute and they are to the right place (There is a CSS link as well that uses the same method and it works fine). I've been using the following, which finds images and CSS just fine but for some reason won't run the .js. [webView loadRequest:requestObj]; I've tried changing the encoding of the files. I had a problem getting the CSS to work until the file was in unicode, but so far no luck. All the Script files are bundled with my project etc. Thanks in advance!

• SQL Server - Searching string with international characters using LIKE clause

  - by Nikhil

  Hi, I have a field 'Description' which can have product descriptions with any unicode characters. If I search for a description which contains an international character, with a LIKE condition (word searched with does not have the international character) I get the following results: Ex: GEWÜRZTRAMINER is one of the descriptions. When I do: Select * from table where Description LIKE '%GEWURZTRAMINER%', it retrieves the entry. When I do: Select * from table where Description LIKE '%GEWURZ%', the entry is not retrieved. (Note: the search condition does not include the Ü but has a U) Is there a way around this so that I can retrieve with '%GEWURZ%' as well? SQl Server 2008

• PHP Variable Encryption

  - by NCoder

  I have the following code that creates an encryption in PHP: $password = "helloworld"; $passwordupper = strtoupper($password); $passwordencode = mb_convert_encoding($passwordupper, 'UTF-16LE'); $passwordsha1 = hash("SHA1", $passwordencode); $passwordbase64 = base64_encode($passwordsha1); The instructions I have from the system I'm trying to connect to states: The encoding process for passwords is: first convert to uppercase, then Unicode it in little-endian UTF 16, then SHA1 it then base64 encode it. I think I'm doing something wrong in my code. Any ideas?! Thanks! NCoder

• What encoding uses Flash Builder to send non english data to server?

  - by Ole Jak

  In my site I use Unicode... I hoped when I'll connect Flash Builder to my server (using Data - connect to HTTP ) It will work with my API sending Russian text as UTF-8 but instead it sends Þûõó ïúушúøý to my API and so to DB and so on instead of my favourite UTF-8 &#1056;&#1091;&#1089;&#1089;&#1082;&#1086;&#1077; &#1048;&#1084;&#1103; 2... So what encoding uses flash builder and How to make Flash Application send UTF-8 data to my server or some other readable format?

• Using xsl:character-map on text nodes only

  - by jramos95

  I am trying to create a generic stylesheet that can convert all Latin characters in Unicode to uppercase ASCII characters. Using <xsl:character-map> works well except for one thing: namespaces. The character map converts all of my namespaces to upper case, which I do not want. Is there a way to utilize a character map to do what I want to all the other nodes while leaving the namespaces untouched? I see the disable-output-escaping attribute might be an option, but I haven't been able to make it work.

• Adding items to dictionary if condition is true, else dont - python

How can I fix it? I'm simply trying to do: if the path.pathval has either ? or & in it: add to dictionary else: pass #forget about it. Thanks!

• How to parse JSON string that can be one of two different strongly typed objects?

  - by user852194

  Background: I'm invoking a web service method which returns a JSON string. This string can be of type ASConInfo or ASErrorResponse. Question: Using the DataContractJsonSerializer, how can I convert the returned JSON string to one of those objects? Thanks in advance I have tried the following technique, but it does not work: public static object test(string inputString) { object obj = null; using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(inputString))) { DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(object)); obj = ser.ReadObject(ms) as object; } return obj; } [WebMethod] public string TypeChecker() { string str = "{\"Error\":191,\"ID\":\"112345678921212\",\"Length\":15}"; //string strErro = ""; object a = test(str); if (a is ASResponse) { return "ASResponse"; } if (a is ASErrorResponse) { return "ASErrorResponse"; } return "Nothing"; }

• is it safe to refactor my django models?

  - by Johnd

  My model is similar to this. Is this ok or should I make the common base class abstract? What are the differcenes between this or makeing it abstract and not having an extra table? It seems odd that there is only one primary key now that I have factored stuff out. class Input(models.Model): details = models.CharField(max_length=1000) user = models.ForeignKey(User) pub_date = models.DateTimeField('date published') rating = models.IntegerField() def __unicode__(self): return self.details class Case(Input): title = models.CharField(max_length=200) views = models.IntegerField() class Argument(Input): case = models.ForeignKey(Case) side = models.BooleanField() is this ok to factor stuff out intpu Input? I noticed Cases and Arguments share a primary Key. like this: CREATE TABLE "cases_input" ( "id" integer NOT NULL PRIMARY KEY, "details" varchar(1000) NOT NULL, "user_id" integer NOT NULL REFERENCES "auth_user" ("id"), "pub_date" datetime NOT NULL, "rating" integer NOT NULL ) ; CREATE TABLE "cases_case" ( "input_ptr_id" integer NOT NULL PRIMARY KEY REFERENCES "cases_input" ("id"), "title" varchar(200) NOT NULL, "views" integer NOT NULL ) ; CREATE TABLE "cases_argument" ( "input_ptr_id" integer NOT NULL PRIMARY KEY REFERENCES "cases_input" ("id"), "case_id" integer NOT NULL REFERENCES "cases_case" ("input_ptr_id"), "side" bool NOT NULL )

• Tallying records using annotate() not working as should.

  - by 47

  I have two classes: Vehicle and Issues....a Vehicle object can have several issues recorded in the Issues class. What I want to do is to have a list of all issues, with each vehicle appearing only once and the total number of issues shown, plus other details....clicking on the record will then take the user to another page with all those issues for a selected vehicle shown in detail now. I tried this out using annotate, but I could only access the count and vehicle foreign key, but none of the other fields in the Vehicle class. class Issues(models.Model): vehicle = models.ForeignKey(Vehicle) description = models.CharField('Issue Description', max_length=30,) type = models.CharField(max_length=10, default='Other') status = models.CharField(max_length=12, default='Pending') priority = models.IntegerField(default='8', editable=False) date_time_added = models.DateTimeField(default=datetime.today, editable=False) last_updated = models.DateTimeField(default=datetime.today, editable=False) def __unicode__(self): return self.description The code I was using to annotate is: issues = Issues.objects.all().values('vehicle').annotate(count=Count('id')) What could be the problem?

• Tag suggestion (not tag autocomplete)

  - by takeshin

  AJAX autocomplete is fairly simple to implement. However, I wonder how to handle smart tag suggestion like this on SO. To clarify the difference between autocomplete and suggestion: autocomplete: foo [foobar, foobaz] suggestion: foo [barfoo, foobar, foobaz], or even better, with 'did you mean' feature: [barfoo, foobar, foobaz, fobar, fobaz] I suppose I need some full text search in tags (all letters indexed, not just words). There would be no problem to do it witch regex or other patterns for limited number of tags (even client side). But how to implement this feature for big number of tags? Is there any particular reason (besides URL) the tags on SO are dash separated? What about Unicode characters in tags? I store the tags in the table with the following columns: id, tagname. My SQL query returns objects with following fields: id, tagname, count

• What weird encoding is movistar Venezuela sms on blackberry using?

  - by cjp

  Send an sms using the normal GSM TextMessage API on the BlackBerry, get back garbage. It's not unicode, phone is set to 7-bit send. Byte size is only off by one. Is there some default crypto thing, or some weird encoding they use? This code works most everywhere else in the world; this definitely seems like a movistar problem. The string that comes back is random 7-bit ascii except for a few high order bytes. Needless to say the source input text is totally 7 bit chars, which should work in sms, ISO-8859 and look the same in UTF charsets. Anybody seen this or got sms working in code on movistar VZ blackberries?

• formatting european characters from JSON results

  - by mlecho

  hi, i am building an application that imports JSON results and parses the objects to a table cell. Nothing fancy, but in my results, many of the terms/names are European with characters such as è or ú which come out as \u00E9 or \u00FA. I think these are ASCII ? or unicode? ( i can never keep em staight). Anyway, like all good NSSTring's, i figured there must be a method to fix this, but i am not finding it....any ideas? I am trying to avoid doing something like this: this posting. Thanks all.

• Will Haskell be a good choice for my task?

  - by Narzanka

  I'm starting a new project and don't know which language to use. My 'must have' requirements are: Be able to run on Windows/LinuxMacOs natively (native executable) - user should be able to just run the exe (when on Windows for example) and see the results. No runtimes/interpreters (no jvm, clr, etc) - one file download should be enough to run the application. Full unicode support. Be able to manipulate OS threads (create them, run multiple tasks in parallel on multi-core CPUs, etc). Be reasonably fast (Python level performance and better). To have some kind of standard library that does low-level, mundane tasks. Not very niche and have some community behind it to be able to ask questions. My 'nice to have' requirements are: Language should be functional It should have good string manipulation capabilities (not necessarily regex) Not extremely hard to learn I'm thinking about Haskell now but keeping in mind OCaml as well. Please advice if my choice is correct.

• Java deserialization speed

  - by celicni

  I am writing a Java application that among other things needs to read a dictionary text file (each line is one word) and store it in a HashSet. Each time I start the application this same file is being read all over again (6 Megabytes unicode file). That seemed expensive, so I decided to serialize resulting HashSet and store it to a binary file. I expected my application to run faster after this. Instead it got slower: from ~2,5 seconds before to ~5 seconds after serialization. Is this expected result? I thought that in similar cases serialization should increase speed.

• Windows C++: LPCTSTR vs const TCHAR

  - by mrl33t

  In my application i'm declaring a string variable near the top of my code to define the name of my window class which I use in my calls to RegisterClassEx, CreateWindowEx etc.. Now, I know that an LPCTSTR is a typedef and will eventually follow down to a TCHAR (well a CHAR or WCHAR depending on whether UNICODE is defined), but I was wondering whether it would be better to use this: static LPCTSTR szWindowClass = TEXT("MyApp"); Or this: static const TCHAR szWindowClass[] = TEXT("MyApp"); I personally prefer the use of the LPCTSTR as coming from a JavaScript, PHP, C# background I never really considered declaring a string as an array of chars. But are there actually any advantages of using one over the other, or does it in fact not even make a difference as to which one I choose? Thank you, in advanced, for your answers.
