• java: speed up reading foreign characters

  - by Yang

  My current code needs to read foreign characters from the web, currently my solution works but it is very slow, since it read char by char using InputStreamReader. Is there anyway to speed it up and also get the job done? // Pull content stream from response HttpEntity entity = response.getEntity(); InputStream inputStream = entity.getContent(); StringBuilder contents = new StringBuilder(); int ch; InputStreamReader isr = new InputStreamReader(inputStream, "gb2312"); // FileInputStream file = new InputStream(is); while( (ch = isr.read()) != -1) contents.append((char)ch); String encode = isr.getEncoding(); return contents.toString();

• How Serializable works with insert in SQL Server 2005

  - by Spence

  G'day I think I have a misunderstanding of serializable. I have two tables (data, transaction) which I insert information into in a serializable transaction (either they are both in, or both out, but not in limbo). SET TRANSACTION ISOLATION LEVEL SERIALIZABLE BEGIN TRANSACTION INSERT INTO dbo.data (ID, data) VALUES (@Id, data) INSERT INTO dbo.transactions(ID, info) VALUES (@ID, @info) COMMIT TRANSACTION I have a reconcile query which checks the data table for entries where there is no transaction at read committed isolation level. INSERT INTO reconciles (ReconcileID, DataID) SELECT Reconcile = @ReconcileID, ID FROM Data WHERE NOT EXISTS (SELECT 1 FROM TRANSACTIONS WHERE data.id = transactions.id) Note that the ID is actually a composite (2 column) key, so I can't use a NOT IN operator My understanding was that the second query would exclude any values written into data without their transaction as this insert was happening at serializable and the read was occurring at read committed. I have evidence that reconcile is picking up entries

• entity framework and dirty reads

  - by bryanjonker

  I have Entity Framework (.NET 4.0) going against SQL Server 2008. The database is (theoretically) getting updated during business hours -- delete, then insert, all through a transaction. Practically, it's not going to happen that often. But, I need to make sure I can always read data in the database. The application I'm writing will never do any types of writes to the data -- read-only. If I do a dirty read, I can always access the data; the worst that happens is I get old data (which is acceptable). However, can I tell Entity Framework to always use dirty reads? Are there performance or data integrity issues I need to worry about if I set up EF this way? Or should I take a step back and see about rewriting the process that's doing the delete/insert process?

• Problem opening Solr *.jsp pages with urllib2.urlopen.

  I'm trying to open a page at http://localhost:8983/solr/admin/stats.jsp but urllib2.urlopen returns a blank string. It works fine for solr/ and solr/admin, but for all the pages above /solr/admin/ I get nothing but a blank string. 76]: t = urllib2.urlopen('http://localhost:8983/solr/admin/stats.jsp') 77]: s = t.read() 78]: s 78]: 79]: type(s) 79]: <type 'str'> 80]: urllib2.urlopen('http://localhost:8983/solr/admin/registry.jsp').read() 80]: In [84]: urllib2.urlopen('http://localhost:8983/solr/admin/schema.jsp').read() Out[84]: I know this isn't a problem with urllib2, but beyond that I am at a loss. I wish solr (or jetty) had an easy to get to log file, so that perhaps it could tell me its side of the story.

• How would I go about writing a Linux TTY sniffer?

  - by alienate

  For educational purposes (not that anyone should care the motivations behind such an exercise) I'd like to write a program that can read/write to/from alternate tty/pty's. I've read papers (from the 1990's) but can't employ the implementation they use, on modern UNIXes. I was hoping that someone had researched into this in the past, or at least, read documentation pertaining to it, that they could provide. I also wonder if (considering the fact that Linux doesn't have STREAMs) if this exercise must be done via a loadable kernel module? I have many questions and probably a misunderstanding of some of the fundamental ideologies that allow such objectives to be put in place, could someone help? :)

• jQuery DataLink - Does DataLink solve my use case?

  - by AnApprentice

  Hello, I recently heard of the jQuery datalink plugin and wondered if I should be using if for the following: I have a an inbox in my app that consists of the following: Inbox (index) - List of Items (list of mails) Inbox (show) Item Viewer (1 mail) Inbox Unread Counter The challenge I'm having now is a user can mark a mail as read/unread in either view which makes keeping the counter accurate challenging. Can datalink help with this? If so how? Also, I read that datalink requires forms is that true? Or can I bind the links to anything like 0 and anytime a mailitem changes from read to unread it would automatically update? Thanks

• How to create a non-persistent Elixir/SQLAlchemy object?

  - by siebert

  Hi, because of legacy data which is not available in the database but some external files, I want to create a SQLAlchemy object which contains data read from the external files, but isn't written to the database if I execute session.flush() My code looks like this: try: return session.query(Phone).populate_existing().filter(Phone.mac == ident).one() except: return self.createMockPhoneFromLicenseFile(ident) def createMockPhoneFromLicenseFile(self, ident): # Some code to read necessary data from file deleted.... phone = Phone() phone.mac = foo phone.data = bar phone.state = "Read from legacy file" phone.purchaseOrderPosition = self.getLegacyOrder(ident) # SQLAlchemy magic doesn't seem to work here, probably because we don't insert the created # phone object into the database. So we set the id fields manually. phone.order_id = phone.purchaseOrderPosition.order_id phone.order_position_id = phone.purchaseOrderPosition.order_position_id return phone Everything works fine except that on a session.flush() executed later in the application SQLAlchemy tries to write the created Phone object to the database (which fortunatly doesn't succeed, because phone.state is longer than the data type allows), which breaks the function which issues the flush. Is there any way to prevent SQLAlchemy from trying to write such an object? Ciao, Steffen

• What segments does C compiled program use?

  - by b-gen-jack-o-neill

  Hi, I read on OSDev wiki, that protected mode of x86 architecture allow you to create separate segments for code and data, while you cannot write into code section. That Windows (yes, this is the platform) loads new code into code segment, and data are created on data segment. But, if this is the case, how does program know it must switch segments to the data segment? Becouse if I understand it right, all adress instructions point to the segment you run the code from, unless you switch the descriptor. But I also read, that so colled flat memory model allows you to run code and data within one segment. But I read this only in connection to assembler. So, please, what is the case with C compiled code on Windows? Thanks.

• International JRE6 or JDK6 or reading a file in "cp037" encoding scheme

  - by Reddy

  I have been trying to read a file in "cp037" encoding scheme using JAVA. I able to read a file in basic encoding schemes like UTF-8, UTF16 etc...After a bit of research on the internet i came to know that we need charset.jar or international version of JRE be installed to support extended encoding schemes. Can anyone send me a link for international version of JRE6 or JDK6. or is there any better way that i could read a file in cp037 encoding scheme. P.S: cp037 is a character encoding scheme supported by IBM Mainframes. All i need is to display a file in windows, which is being generated on IBM Mainframes machine, using a java program. Thanks in advance for your help... :-)

• Which twitter client can synchronize unread tweets?

  - by Tom Burger

  Right now I'm forced to read all the tweets in a single client on a single device (TweetDeck on my Android phone). If I would switch to another device and/or client, I would need to search for the last unread tweet, which is sometimes complicated (too many tweets). So, the question: Is there a client who can keep the status (read/unread) on tweets across multiple devices? My target systems would be now Android and MS Windows, but also Linux might be handy.

• Update music file details - Java.

  - by Desorder

  Hi all, Well, I'm a music fan guy, and now with my 18000 music collection, it's getting very hard to maintain. So, I would like to ask I could of question to help to write an app to maintain it for me. 1- How can I access a music file and read details of it?

I would like to achieve a final result of given a directory, my app would read the file, collect some information and query the source for a complete list of detail and update my file. Thank you guys for any help...

• Reading a simple Avro file from HDFS

  - by John Galt... who

  I am trying to do a simple read of an Avro file stored in HDFS. I found out how to read it when it is on the local file system.... FileReader reader = DataFileReader.openReader(new File(filename), new GenericDatumReader()); for (GenericRecord datum : fileReader) { String value = datum.get(1).toString(); System.out.println("value = " value); } reader.close(); My file is in HDFS, however. I cannot give the openReader a Path or an FSDataInputStream. How can I simply read an Avro file in HDFS? EDIT: I got this to work by creating a custom class (SeekableHadoopInput) that implements SeekableInput. I "stole" this from "Ganglion" on github. Still, seems like there would be a Hadoop/Avro integration path for this. Thanks

• Drupal does not recognize my website has been installed

  - by Marcos Buarque

  After a successful Drupal install, I was trying to follow the security recommendations and reverted the settings.php file to 444 permissions (read, read, read). Then, all of a sudden, right after doing that, Drupal does not recognize the installation process was completed. It went back to the install screen. Worst of all. I did chmod back to 666 (write, write, write) but it does not work any more. When I move forward as if I was going to install Drupal again, he tells me he does not have permissions to create the files folder under sites/default... But since the installation has already been completed... the files folder is already there... I am puzzled... Could it be some sort of server caching? Since this is one of my first adventures with a Linux server, I am a bit confused. Any help appreciated... Thanks.

• Config file format

  - by Felics

  Hello, does anyone knows a file format for configuration files easy to read by humans? I want to have something like tag = value where value may be: String Number(int or float) Boolean(true/false) Array(of String values, Number values, Boolean values) Another structure(it will be more clear what I mean in the fallowing example) Now I use something like this: IntTag=1 FloatTag=1.1 StringTag="a string" BoolTag=true ArrayTag1=[1 2 3] ArrayTag2=[1.1 2.1 3.1] ArrayTag3=["str1" "str2" "str3"] StructTag= { NestedTag1=1 NestedTag2="str1" } and so on. Parsing is easy but for large files I find it hard to read/edit in text editors. I don't like xml for the same reason, it's hard to read. INI does not support nesting and I want to be able to nest tags. I also don't want a complicated format because I will use limited kind of values as I mentioned above. Thanks for any help.

• Do Managers in Python Multiprocessing module lock the shared data?

  - by AnonProcess

  This Question has been asked before: http://stackoverflow.com/questions/2936626/how-to-share-a-dictionary-between-multiple-processes-in-python-without-locking However I have several doubts regarding the program given in the answer: The issue is that the following step isn't atomic d['blah'] += 1 Even with locking the answer provided in that question would lead to random results. Since Process 1 read value of d['blah'] saves it on the stack increments it and again writes it. In Between a Process 2 can read the d['blah'] as well. Locking means that while d['blah'] is being written or read no other process can access it. Can someone clarify my doubts?
