  • Should I use a binary or a text file for storing protobuf messages?

    - by nbolton
    Using Google protobuf, I am saving my serialized messaged data to a file - in each file there are several messages. We have both C++ and Python versions of the code, so I need to use protobuf functions that are available in both languages. I have experimented with using SerializeToArray and SerializeAsString and there seems to be the following unfortunate conditions: SerializeToArray: As suggested in one answer, the best way to use this is to prefix each message with it's data size. This would work great for C++, but in Python it doesn't look like this is possible - am I wrong? SerializeAsString: This generates a serialized string equivalent to it's binary counterpart - which I can save to a file, but what happens if one of the characters in the serialization result is \n - how do we find line endings, or the ending of messages for that matter? Update: Please allow me to rephrase slightly. As I understand it, I cannot write binary data in C++ because then our Python application cannot read the data, since it can only parse string serialized messages. Should I then instead use SerializeAsString in both C++ and Python? If yes, then is it best practice to store such data in a text file rather than a binary file? My gut feeling is binary, but as you can see this doesn't look like an option.

  • using .NET how to convert iso8859-1 encoded text files that contain Latin-1 accented characters to u

    - by Tim
    I am being sent text files saved in iso88591-1 format that contain accented characters from the Latin-1 range (as well as normal ASCII a-z etc). How to convert these files to utf-8 using C# so that the single-byte accented characters in iso8859-1 become valid utf-8 characters? I have tried to use a StreamReader with ASCIIEncoding, and then converting the ascii string to UTF-8 by instantiating an ascii encoding and a utf8 encoding and then using Encoding.Convert(ascii, utf8, ascii.GetBytes( asciiString) ) — but the accented characters are being rendered as question marks. What step am I missing?

  • How do I install the vi text editor ONLY on my Cygwin installation?

    - by gath
    I have managed to install the Cygwin on my Windows Vista machine. I installed using the default settings. When I try to do vi in the Bash shell, Bash tells me command not found. I believe I need to install the Cygwin editors package which include the vi editor. The nightmare is every time I run the Cygwin setup and select ONLY the editors package and specifically the Vim and select install, Cygwin setup tries to install all other packages, very frustrating!! Is there an easier way of installing just a single package using the Cygwin setup utility?

  • Help! Obj-C/Iphone programming: extracting string from html text and reading off line by line

    - by royden
    hihi, I have this html text response from a particular website: <tr><td valign="top"><img src="/icons/image2.gif" alt="[IMG]"></td><td><a href="crsdsdfs2221.jpg">crash-2221.jpg</a></td><td align="right">14-Jun-2010 14:29 Notice for every line, there is this href=".__", which is an image file with random name and random format. I would like to extract that string within the inverted commas out so that i can append it into a URL path and download the image. I've been looking through this documentation from apple: http://developer.apple.com/mac/library/documentation/cocoa/conceptual/strings/Articles/SearchingStrings.html#//apple_ref/doc/uid/20000149-CJBBGBAI on String programming but couldn't find one that fits my bill. Also after reading it, what code can I use to ensure that I will be reading the next line the next time my function is called( because I want to download the next picture). Hope some kind soul can help me out, thanks!

  • VST plugin : using FFT on audio input buffer with arbitrary size, how ?

    - by Led
    I'm getting interested in programming a VST plugin, and I have a basic knowledge of audio dsp's and FFT's. I'd like to use VST.Net, and I'm wondering how to implement an FFT-based effect. The process-code looks like public override void Process(VstAudioBuffer[] inChannels, VstAudioBuffer[] outChannels) If I'm correct, normally the FFT would be applied on the input, some processing would be done on the FFT'd data, and then an inverse-FFT would create the processed soundbuffer. But since the FFT works on a specified buffersize that will most probably be different then the (arbitrary) amount of input/output-samples, how would you handle this ?

  • Which would be better? Storing/access data in a local text file, or in a database?

    - by TerranRich
    Basically, I'm still working on a puzzle-related website (micro-site really), and I'm making a tool that lets you input a word pattern (e.g. "r??n") and get all the matching words (in this case: rain, rein, ruin, etc.). Should I store the words in local text files (such as words5.txt, which would have a return-delimited list of 5-letter words), or in a database (such as the table Words5, which would again store 5-letter words)? I'm looking at the problem in terms of data retrieval speeds and CPU server load. I could definitely try it both ways and record the times taken for several runs with both methods, but I'd rather hear it from people who might have had experience with this. Which method is generally better overall?

  • What is the effect on record size of reordering columns in PostgreSQL?

    - by Summer
    Since Postgres can only add columns at the end of tables, I end up re-ordering by adding new columns at the end of the table, setting them equal to existing columns, and then dropping the original columns. So, what does PostgreSQL do with the memory that's freed by dropped columns? Does it automatically re-use the memory, so a single record consumes the same amount of space as it did before? But that would require a re-write of the whole table, so to avoid that, does it just keep a bunch of blank space around in each record? Thanks! ~S

  • Need text editor that can save locally AND via FTP for Linux - switching from EditPlus on windows

    - by Cyrcle
    I just switched from Windows to Linux. I've been using EditPlus for many years mainly because of it's ability to save locally, and then send the file via FTP, with easy keyboard shortcuts (ctrl-s to save, ctrl-alt-s to ftp). I also need syntax highlighting and basic code editing features. Is there anything for Linux that can do this? I don't want to run EditPlus via Wine

  • LINQ to XML - How to get Dictionary from Anonymous Object?

    - by DaveDev
    Currently I'm getting a list of HeaderColumns from the following XML snippet: <PerformancePanel> <HeaderColumns> <column performanceId="12" text="Over last month %" /> <column performanceId="13" text="Over last 3 months %" /> <column performanceId="16" text="1 Year %" /> <column performanceId="18" text="3 Years % p.a." /> <column performanceId="20" text="5 Years % p.a." /> <column performanceId="22" text="10 Years % p.a." /> </HeaderColumns> </PerformancePanel> from which I create an object as follows: (admitedly similar to an earlier question!) var performancePanels = new { Panels = (from panel in doc.Elements("PerformancePanel") select new { HeaderColumns = (from column in panel.Elements("HeaderColumns").Elements("column") select new { PerformanceId = (int)column.Attribute("performanceId"), Text = (string)column.Attribute("text") }).ToList(), }).ToList() }; I'd like if HeaderColumns was a Dictionary() so later I extract the values from the anonymous object like follows: Dictionary<int, string> myHeaders = new Dictionary<int, string>(); foreach (var column in performancePanels.Panels[0].HeaderColumns) { myHeaders.Add(column.PerformanceId, column.Text); } I thought I could achieve this with the Linq to XML with something similar to this HeaderColumns = (from column in panel.Elements("HeaderColumns").Elements("column") select new Dictionary<int, string>() { (int)column.Attribute("performanceId"), (string)column.Attribute("text") }).ToDictionary<int,string>(), but this doesn't work because ToDictionary() needs a Func parameter and I don't know what that is / how to implement it, and the code's probably wrong anyway! Could somebody please suggest how I can achieve the result I need? Thanks.

  • Excel - Disable AutoFormatting on Import

    - by Philip Wales
    How can I stop Microsoft Excel from auto formatting data when imported from a text file? Specifically, I want it to treat all of the values as text. I am auditing insurance data in excel before it is uploaded to the new database. The files come to me as tab delimited text files. When loaded, Excel auto-formats the data causing leading 0's on Zip Codes, Routing Numbers and other codes, to be chopped off. I don't have the patience to reformat all of the columns as text and guess how many zeros need to be replaced. Nor do I want to click through the import wizard an specify that each column is text. Ideally I just want to turn off Excel's Auto-Formatting completely, and just edit every cell as it were plain text. I don't do any formula's or charts, just grid plain text editing.

  • Fastest way to store/retrieve a dictionary - SQL, text file...?

    - by AP257
    Hi all, This is a really really super dumb question, so I apologise, but I'd be grateful for some advice. I've got a text file of words and word frequencies. It's very large - theoretically we're talking millions of rows. I just want to retrieve values from the file, and do it as quickly and efficiently as possible (for a web app, in Django). My question is: what is the best way to store and retrieve the values? Should import them into SQL? Or keep the file and use grep? Or put them into a JSON dictionary...? Or some other way? Sorry for the dumb question, would be very grateful for advice!

  • How to unmangle PDF format into a usable text or spreadsheet document?

    - by Chuck
    Upon requesting some daily/hourly sales data from a coworker who is responsible for such requests, I was given a series of PDF files. The point of sale program that is used, for some reason, answers requests for this type of information in the form of PDF files. The issue: The PDF files look to be in a format that should easily be copy and pasted into a spreadsheet. There are three columns that look to be neatly organized across two pages. When copy/pasting the first page, all three columns from the PDF's first page are dumped into a single column consisting of the Date followed by the Hours for the transactions on that day. The end of this Date/Time information is followed by all of the Total Sales values that should be attached a Date and Time of the transaction. (NOTE: There are no duplicated Dates in the Date column, ie, Multiple transactions for a day only have one yyyy/mm/dd listed for the first row but not the following rows.) While it was a huge pain, it was possible to, in about four or five steps, get the single column of data broken out into three columns that matched the PDF. The second page of the PDF file, when attempting to copy/paste into a spreadsheet, creates a single column with the first third of the cells being the Dates from the PDF, the second third of the cells being the Hours of the transactions and the final third of the cells being filled with the Total Sales. After the copy/paste there is no way to figure out which Hours belong to which Dates or Total Sales due to the lack of the duplicated Dates in the Date column as mentioned above. My PDF-fu is next to non-existent. I've just now started to work with PDF editors and some www.convertmyPDFforfree.com websites, so far, with absolutely nothing remotely coming anywhere near usable output. (Both methods have so far done nothing but product blank documents.) Before I go back and pester my co-worker into figuring out a way to create a report in some other format than PDF, is there any method by which to take the data that looks to be formatted correctly in a PDF and copy/paste it into a spreadsheet that will look the same? I appreciate any help that can be made available. The sales data isn't so sensitive that I couldn't part with a bit to let somebody actually see what it is that needs to be dealt with, just let me know. The PDF's are less than 100kb each so sending them shouldn't be a burden to any interested party.

  • How to remove hyperlink but keep text for an array of links?

    - by Keith Donegan
    My question is fairly similar to this question: Remove hyperlink but keep text? but, I can't seem to workout how I can feed an array of class names and do this in one go? For Example <a class="unwrap" href="#">Blah</a> <a class="unwrap" href="#">Blah</a> <a href="#">Blah</a> <a class="unwrap" href="#">Blah</a> I would just like the links with the unwrap class to be modified.

  • How to store multiple variables from a File Input of unknown size in Java?

    - by AlphaOmegaStrife
    I'm a total beginner with my first programming assignment in Java. For our programming assignment, we will be given a .txt file of students like so: 3 345 Lisa Miller 890238 Y 2 <-(Number of classes) Mathematics MTH345 4 A Physics PHY357 3 B Bill Wilton 798324 N 2 English ENG378 3 B Philosophy PHL534 3 A Dandy Goat 746333 Y 1 History HIS101 3 A" The teacher will give us a .txt file on the day of turning it in with a list of unknown students. My problem is: I have a specific class for turning the data from the file into variables to be used for a different class in printing it to the screen. However, I do not know of a good way to get the variables from the input file for the course numbers, since that number is not predetermined. The only way I can think of to iterate over that unknown amount is using a loop, but that would just overwrite my variables every time. Also, the teacher has requested that we not use any JCL classes (I don't really know what this means.) Sorry if I have done a poor job of explaining this, but I can't think of a better way to conceptualize it. Let me know if I can clarify. Edit: public static void analyzeData() { Scanner inputStream = null; try { inputStream = new Scanner(new FileInputStream("Programming Assignment 1 Data.txt")); } catch (FileNotFoundException e) { System.out.println("File Programming Assignment 1 Data.txt could not be found or opened."); System.exit(0); } int numberOfStudents = inputStream.nextInt(); int tuitionPerHour = inputStream.nextInt(); String firstName = inputStream.next(); String lastname = inputStream.next(); String isTuitionPaid = inputStream.next(); int numberOfCourses = inputStream.nextInt(); String courseName = inputStream.next(); String courseNumber = inputStream.next(); int creditHours = inputStream.nextInt(); String grade = inputStream.next(); To show the methods I am using now, I am just using a Scanner to read from the file and for Scanner inputStream, I am using nextInt() or next() to get variables from the file. Obviously this will not work when I do not know exactly how many classes each student will have.

  • Reading bytes from a text file that has the form of machine code in C?

    - by rashid
    I have a text file with machine code in this form: B2 0A 05 B2 1A 01 B3 08 00 17 B2 09 18 where an instruction has this format: OP Mode Operand Note: Operand could be 1 or 2 bytes. Where:(example) OP = B2 Mode = 0A Operand = 05 How can I read the bytes in a variable? As shown in the above example. When i read the file I get individual characters. I have an array of pointers where I read individual line, but still cannot solve the problem of reading a byte. Any ideas,suggestions. I hope I am not confusing anyone here. Thank you.

  • How to modify the Title Bar text for SQL Server Management Studio?

    - by DaveDev
    Sometimes I keep multiple instances of SQL Server Management Studio 2005 open. I might have the dev database open in one, and the production database open in another. These appear in the Windows task bar with the text "Microsoft SQL Serve...", which means it's impossible to differentiate between them unless I open the window and scroll the Object Explorer up to see what server the window is actually connected to. Is ther any way that I can get the window to display the server name first, and then the name of the application? Like "Dev-DB.database_name - Microsoft SQL Serve..." or whatever?

  • Keeping User-Input UITextVIew Content Constrained to Its Own Frame

    - by siglesias
    Trying to create a large textbox of fixed size. This problem is very similar to the 140 character constraint problem, but instead of stopping typing at 140 characters, I want to stop typing when the edge of the textView's frame is reached, instead of extending below into the abyss. Here is what I've got for the delegate method. Seems to always be off by a little bit. Any thoughts? - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text { BOOL edgeBump = NO; CGSize constraint = textView.frame.size; CGSize size = [[textView.text stringByAppendingString:text] sizeWithFont:textView.font constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap]; CGFloat height = size.height; if (height > textView.frame.size.height) { edgeBump = YES; } if([text isEqualToString:@"\b"]){ return YES; } else if(edgeBump){ NSLog(@"EDGEBUMP!"); return NO; } return YES; } EDIT: As per Max's suggestion below, here is the code that works: - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text { CGSize constraint = textView.frame.size; NSString *whatWasThereBefore = textView.text; textView.text = [textView.text stringByReplacingCharactersInRange:range withString:text]; if (textView.contentSize.height >= constraint.height) { textView.text = whatWasThereBefore; } return NO; }
