• Can't get MySQL source query to work using Python mysqldb module

  - by Chris

  I have the following lines of code: sql = "source C:\\My Dropbox\\workspace\\projects\\hosted_inv\\create_site_db.sql" cursor.execute (sql) When I execute my program, I get the following error: Error 1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'source C:\My Dropbox\workspace\projects\hosted_inv\create_site_db.sql' at line 1 Now I can copy and past the following into mysql as a query: source C:\\My Dropbox\\workspace\\projects\\hosted_inv\\create_site_db.sql And it works perfect. When I check the query log for the query executed by my script, it shows that my query was the following: source C:\\My Dropbox\\workspace\\projects\\hosted_inv\\create_site_db.sql However, when I manually paste it in and execute, the entire create_site_db.sql gets expanded in the query log and it shows all the sql queries in that file. Am I missing something here on how mysqldb does queries? Am I running into a limitation. My goal is to run a sql script to create the schema structure, but I don't want to have to call mysql in a shell process to source the sql file. Any thoughts? Thanks!

• Some general C questions.

  - by b-gen-jack-o-neill

  Hello. I am trying to fully understand the process pro writing code in some language to execution by OS. In my case, the language would be C and the OS would be Windows. So far, I read many different articles, but I am not sure, whether I understand the process right, and I would like to ask you if you know some good articles on some subjects I couldn´t find. So, what I think I know about C (and basically other languages): C compiler itself handles only data types, basic math operations, pointers operations, and work with functions. By work with functions I mean how to pass argument to it, and how to get output from function. During compilation, function call is replaced by passing arguments to stack, and than if function is not inline, its call is replaced by some symbol for linker. Linker than find the function definition, and replace the symbol to jump adress to that function (and of course than jump back to program). If the above is generally true and I get it right, where to final .exe file actually linker saves the functions? After the main() function? And what creates the .exe header? Compiler or Linker? Now, additional capabilities of C, today known as C standart library is set of functions and the declarations of them, that other programmers wrote to extend and simplify use of C language. But these functions like printf() were (or could be?) written in different language, or assembler. And there comes my next question, can be, for example printf() function be written in pure C without use of assembler? I know this is quite big question, but I just mostly want to know, wheather I am right or not. And trust me, I read a lots of articles on the web, and I would not ask you, If I could find these infromation together on one place, in one article. Insted I must piece by piece gather informations, so I am not sure if I am right. Thanks.

• TDD vs. Unit testing

  - by Walter

  My company is fairly new to unit testing our code. I've been reading about TDD and unit testing for some time and am convinced of their value. I've attempted to convince our team that TDD is worth the effort of learning and changing our mindsets on how we program but it is a struggle. Which brings me to my question(s). There are many in the TDD community who are very religious about writing the test and then the code (and I'm with them), but for a team that is struggling with TDD does a compromise still bring added benefits? I can probably succeed in getting the team to write unit tests once the code is written (perhaps as a requirement for checking in code) and my assumption is that there is still value in writing those unit tests. What's the best way to bring a struggling team into TDD? And failing that is it still worth writing unit tests even if it is after the code is written? EDIT What I've taken away from this is that it is important for us to start unit testing, somewhere in the coding process. For those in the team who pickup the concept, start to move more towards TDD and testing first. Thanks for everyone's input. FOLLOW UP We recently started a new small project and a small portion of the team used TDD, the rest wrote unit tests after the code. After we wrapped up the coding portion of the project, those writing unit tests after the code were surprised to see the TDD coders already done and with more solid code. It was a good way to win over the skeptics. We still have a lot of growing pains ahead, but the battle of wills appears to be over. Thanks for everyone who offered advice!

• How to write a decent process filter?

  - by konr

  Hi there, I'm building a program that communicates with Emacs, and one of the challenges I'm facing is writing Emacs's process filter function. Its input string is a series of s-expressions to be evaluated. Here is a sample: (gimme-append-to-buffer "25 - William Christie dir, Les Arts Florissants - Scene 2. Prelude - Les Arts Florissants\n") (gimme-append-to-buffer "26 - William Christie dir, Les Arts Florissants - Cybele: 'Je Veux Joindre' - Les Arts Florissants\n") (gimme-append-to-buffer "27 - William Christie dir, Les Arts Florissants - Scene 3. Cybele: 'Tu T'Etonnes, Melisse' - Les Arts Florissants\n") (gimme-append-to-buffer "28 - William Christie dir, Les Arts Florissants - Cybele: 'Que Les Plus Doux Zephyrs'. Scene 4. - Les Arts Florissants\n") (gimme-append-to-buffer "29 - William Christie dir, Les Arts Florissants - Entree Des Nations - Les Arts Florissants\n") (gimme-append-to-buffer "30 - William Christie dir, Les Arts Florissants - Entree Des Zephyrs - Les Arts Florissants\n") (gimme-append-to-buffer "31 - William Christie dir, Les Arts Florissants - Choeur Des Nations' 'Que Devant Vous' - Les Arts Florissants\n") (gimme-append-to-buffer "32 - William Christie dir, Les Arts Florissants - Atys: 'Indigne Que Je Suis' - Les Arts Florissants\n") (gimme-append-to-buffer "33 - William Christie dir, Les Arts Florissants - Reprise Du Choeur Des Nations : 'Que Devant Nous' - Les Arts Florissants\n") (gimme-append-to-buffer "34 - William Christie dir, Les Arts Flor*emphasized text*issants - Reprise De L'Air Des Zephyrs - Les Arts Florissants\n") The first problem that I've faced is that the string is somehow not fully formed when the function is so called, so writing something like (mapcar 'eval (format "(%s)" input-string)) won't work. To deal with this first problem, I was using a loop. The full function I wrote is: (defun eval-all-sexps (s) (loop for x = (ignore-errors (read-from-string s)) then (ignore-errors (read-from-string (substring s position))) while x summing (or (cdr x) 0) into position doing (eval (car x)))) Now the second problem that showed up is that the function is called twice with a somewhat large input, first with valid but partial content, then with what looks like pieces of the remaining data. To solve this problem, I'm considering using a junk variable to hold up what remains from a loop and then concatenating it to the input of the next call, but I was wondering if you guys have any other suggestions on how to deal with such a problem more elegantly. Thanks!

• Hadoop streaming with Python and python subprocess

  - by Ganesh

  I have established a basic hadoop master slave cluster setup and able to run mapreduce programs (including python) on the cluster. Now I am trying to run a python code which accesses a C binary and so I am using the subprocess module. I am able to use the hadoop streaming for a normal python code but when I include the subprocess module to access a binary, the job is getting failed. As you can see in the below logs, the hello executable is recognised to be used for the packaging, but still not able to run the code. . . packageJobJar: [/tmp/hello/hello, /app/hadoop/tmp/hadoop-unjar5030080067721998885/] [] /tmp/streamjob7446402517274720868.jar tmpDir=null JarBuilder.addNamedStream hello . . 12/03/07 22:31:32 INFO mapred.FileInputFormat: Total input paths to process : 1 12/03/07 22:31:32 INFO streaming.StreamJob: getLocalDirs(): [/app/hadoop/tmp/mapred/local] 12/03/07 22:31:32 INFO streaming.StreamJob: Running job: job_201203062329_0057 12/03/07 22:31:32 INFO streaming.StreamJob: To kill this job, run: 12/03/07 22:31:32 INFO streaming.StreamJob: /usr/local/hadoop/bin/../bin/hadoop job -Dmapred.job.tracker=master:54311 -kill job_201203062329_0057 12/03/07 22:31:32 INFO streaming.StreamJob: Tracking URL: http://master:50030/jobdetails.jsp?jobid=job_201203062329_0057 12/03/07 22:31:33 INFO streaming.StreamJob: map 0% reduce 0% 12/03/07 22:32:05 INFO streaming.StreamJob: map 100% reduce 100% 12/03/07 22:32:05 INFO streaming.StreamJob: To kill this job, run: 12/03/07 22:32:05 INFO streaming.StreamJob: /usr/local/hadoop/bin/../bin/hadoop job -Dmapred.job.tracker=master:54311 -kill job_201203062329_0057 12/03/07 22:32:05 INFO streaming.StreamJob: Tracking URL: http://master:50030/jobdetails.jsp?jobid=job_201203062329_0057 12/03/07 22:32:05 ERROR streaming.StreamJob: Job not Successful! 12/03/07 22:32:05 INFO streaming.StreamJob: killJob...

• Decrypting a string in C# which was encrypted with openssl in php 5.3.2

  - by panny

  maybe someone can clear me up. I have been surfing on this a while now. I used openssl from console to create a root certificate for me (privatekey.pem, publickey.pem, mycert.pem, mycertprivatekey.pfx). See the end of this text on how. The problem is still to get a string encrypted on the PHP side to be decrypted on the C# side with RSACryptoServiceProvider. Any ideas? PHP side I used the publickey.pem to read it into php: $server_public_key = openssl_pkey_get_public(file_get_contents("C:\publickey.pem")); // rsa encrypt openssl_public_encrypt("123", $encrypted, $server_public_key); and the privatekey.pem to check if it works: openssl_private_decrypt($encrypted, $decrypted, openssl_get_privatekey(file_get_contents("C:\privatekey.pem"))); Coming to the conclusion, that encryption/decryption works fine on the php side with these openssl root certificate files. C# side In same manner I read the keys into a .net C# console program: X509Certificate2 myCert2 = new X509Certificate2(); RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(); try { myCert2 = new X509Certificate2(@"C:\mycertprivatekey.pfx"); rsa = (RSACryptoServiceProvider)myCert2.PrivateKey; } catch (Exception e) { } string t = Convert.ToString(rsa.Decrypt(rsa.Encrypt(test, false), false)); coming to the point, that encryption/decryption works fine on the c# side with these openssl root certificate files. key generation on unix 1) openssl req -x509 -nodes -days 3650 -newkey rsa:1024 -keyout privatekey.pem -out mycert.pem 2) openssl rsa -in privatekey.pem -pubout -out publickey.pem 3) openssl pkcs12 -export -out mycertprivatekey.pfx -in mycert.pem -inkey privatekey.pem -name "my certificate"

• Compiling external C++ library (Octave) for iPhone (Fortran compiler missing?)

  - by Shaggy Frog

  A friend of mine asked me if it would be possible to port the Octave project to the iPhone. I haven't compiled an external package for an iPhone project before, so I downloaded the source code, and then used some scripts found on a couple of different Web sites (one, two) to try and build the libraries. However, when I try either of these scripts (which are nearly identical), they eventually die during the configure phase with the following error output: [...snip checks...] checking whether we are using the GNU Fortran 77 compiler... no checking whether accepts -g... no checking how to get verbose linking output from ... configure: WARNING: compilation failed checking for Fortran 77 libraries of ... rm: conftest.dSYM: is a directory checking for dummy main to link with Fortran 77 libraries... rm: conftest.dSYM: is a directory none checking for Fortran 77 name-mangling scheme... configure: error: cannot compile a simple Fortran program See `config.log' for more details. Is the problem that the iPhone SDK/Xcode doesn't include a Fortran cross-compiler, or am I doing something wrong?

• How do you invoke a python script inside a jar file using python ?

  - by Trevor

  I'm working on an application that intersperses a bunch of jython and java code. Due to the nature of the program (using wsadmin) we are really restricted to Python 2.1 We currently have a jar containing both java source and .py modules. The code is currently invoked using java, but I'd like to remove this in favor of migrating as much functionality as possible to jython. The problem I have is that I want to either import or execute python modules inside the existing jar file from a calling jython script. I've tried a couple of different ways without success. My directory structure looks like: application.jar |-- com |--example |-- action |-- MyAction.class |-- pre_myAction.py The 1st approach I tried was to do imports from the jar. I added the jar to my sys.path and tried to import the module using both import com.example.action.myAction and import myAction. No success however, even when I put init.py files into the directory at each level. The 2nd approach I tried was to load the resource using the java class. So I wrote the below code: import sys import os import com.example.action.MyAction as MyAction scriptName = str(MyAction.getResource('/com/example/action/myAction.py')) scriptStr = MyAction.getResourceAsStream('/com/example/action/myAction.py') try: print execfile(scriptStr) except: print "failed 1" try: print execfile(scriptName) except: print "failed 2" Both of these failed. I'm at a bit of a loss now as to how I should proceed. Any ideas ? cheers, Trevor

• SQLiteDataAdapter Fill exception C# ADO.NET

  - by Lirik

  I'm trying to use the OleDb CSV parser to load some data from a CSV file and insert it into a SQLite database, but I get an exception with the OleDbAdapter.Fill method and it's frustrating: An unhandled exception of type 'System.Data.ConstraintException' occurred in System.Data.dll Additional information: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. Here is the source code: public void InsertData(String csvFileName, String tableName) { String dir = Path.GetDirectoryName(csvFileName); String name = Path.GetFileName(csvFileName); using (OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dir + @";Extended Properties=""Text;HDR=No;FMT=Delimited""")) { conn.Open(); using (OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM " + name, conn)) { QuoteDataSet ds = new QuoteDataSet(); adapter.Fill(ds, tableName); // <-- Exception here InsertData(ds, tableName); // <-- Inserts the data into the my SQLite db } } } class Program { static void Main(string[] args) { SQLiteDatabase target = new SQLiteDatabase(); string csvFileName = "D:\\Innovations\\Finch\\dev\\DataFeed\\YahooTagsInfo.csv"; string tableName = "Tags"; target.InsertData(csvFileName, tableName); Console.ReadKey(); } } The "YahooTagsInfo.csv" file looks like this: tagId,tagName,description,colName,dataType,realTime 1,s,Symbol,symbol,VARCHAR,FALSE 2,c8,After Hours Change,afterhours,DOUBLE,TRUE 3,g3,Annualized Gain,annualizedGain,DOUBLE,FALSE 4,a,Ask,ask,DOUBLE,FALSE 5,a5,Ask Size,askSize,DOUBLE,FALSE 6,a2,Average Daily Volume,avgDailyVolume,DOUBLE,FALSE 7,b,Bid,bid,DOUBLE,FALSE 8,b6,Bid Size,bidSize,DOUBLE,FALSE 9,b4,Book Value,bookValue,DOUBLE,FALSE I've tried the following: Removing the first line in the CSV file so it doesn't confuse it for real data. Changing the TRUE/FALSE realTime flag to 1/0. I've tried 1 and 2 together (i.e. removed the first line and changed the flag). None of these things helped... One constraint is that the tagId is supposed to be unique. Here is what the table look like in design view: Can anybody help me figure out what is the problem here?

• Why can't the compiler/JVM just make autoboxing "just work"?

  - by Pyrolistical

  Autoboxing is rather scary. While I fully understand the difference between == and .equals I can't but help have the follow bug the hell out of me: final List<Integer> foo = Arrays.asList(1, 1000); final List<Integer> bar = Arrays.asList(1, 1000); System.out.println(foo.get(0) == bar.get(0)); System.out.println(foo.get(1) == bar.get(1)); That prints true false Why did they do it this way? It something to do with cached Integers, but if that is the case why don't they just cache all Integers used by the program? Or why doesn't the JVM always auto unbox to primitive? Printing false false or true true would have been way better. EDIT I disagree about breakage of old code. By having foo.get(0) == bar.get(0) return true you already broke the code. Can't this be solved at the compiler level by replacing Integer with int in byte code (as long as it is never assigned null)

• Java/BlackBerry build error overriding too many classes

  - by behrk2

  Hey everyone, Has anyone ever heard of overriding too many classes in Java? Perhaps this issue is just related to BlackBerry development, but I was wondering if it is an issue in Java, too. Let's say I have the following: LabelField lblTitle = new LabelField(title) { protected void paint(Graphics graphics) { graphics.setColor(0x00FFFFFF); graphics.clear(); super.paint(graphics); } }; LabelField lblSubTitle = new LabelField(releaseYear + ", " + rating) { protected void paint(Graphics graphics) { graphics.setColor(0x00FFFFFF); graphics.clear(); super.paint(graphics); } }; This code works. However, I've noticed that by overriding the paint() method multiple times in many different classes throughout my project, I receive the error: I/O Error: Cannot run program "jar": CreateProcess error=2, The system cannot find the file specified My only solution thus far is to clean up my GUI code...minimize it and reuse it. Perhaps its good that this happened so I can be less careless about creating GUI code all over my classes. Anyways, I was just wondering if anyone has heard of this before. If you are interested in reading more about the issue I have been facing, check out the following link: BlackBerry Java Development Forums

• SQLiteDataAdapter Update method returning 0 C#

  - by Lirik

  I loaded 83 rows from my CSV file, but when I try to update the SQLite database I get 0 rows... I can't figure out what I'm doing wrong. The program outputs: Num rows loaded is 83 Num rows updated is 0 The source code is: public void InsertData(String csvFileName, String tableName) { String dir = Path.GetDirectoryName(csvFileName); String name = Path.GetFileName(csvFileName); using (OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dir + @";Extended Properties=""Text;HDR=Yes;FMT=Delimited\""")) { conn.Open(); using (OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM " + name, conn)) { QuoteDataSet ds = new QuoteDataSet(); adapter.Fill(ds, tableName); Console.WriteLine("Num rows loaded is " + ds.Tags.Rows.Count); InsertData(ds, tableName); } } } public void InsertData(QuoteDataSet data, String tableName) { using (SQLiteConnection conn = new SQLiteConnection(_connectionString)) { using (SQLiteDataAdapter sqliteAdapter = new SQLiteDataAdapter("SELECT * FROM " + tableName, conn)) { using (new SQLiteCommandBuilder(sqliteAdapter)) { conn.Open(); Console.WriteLine("Num rows updated is " + sqliteAdapter.Update(data, tableName)); } } } } Any hints on why it's not updating the correct number of rows?

• Debugging a release only flash problem

  - by Fire Lancer

  I've got an Adobe Flash 10 program that freezes in certain cases, however only when running under a release version of the flash player. With the debug version, the application works fine. What are the best approaches to debugging such issues? I considered installing the release player on my computer and trying to set some kind of non-graphical method of output up (I guess there's some way to write a log file or similar?), however I see no way to have both the release and debug versions installed anyway :( . EDIT: Ok I managed to replace my version of flash player with the release version, and no freeze...so what I know so far is: Flash: Debug Release Vista 32: works works XP PRO 32: works* freeze I gave them the debug players I had to test this Hmm, seeming less and less like an error in my code and more like a bug in the player (10.0.45.2 in all cases)... At the very least id like to see the callstack at the point it freezes. Is there some way to do that without requiring them to install various bits and pieces, e.g. by letting flash write out a log.txt or something with a "trace" like function I can insert in the code in question? EDIT2: I just gave the swf to another person with XP 32bit, same results :(

• iPhone app memory leak with UIImage animation? Problem testing on device

  - by user157733

  I have an animation which works fine in the simulator but crashes on the device. I am getting the following error... Program received signal: “0”. The Debugger has exited due to signal 10 (SIGBUS) A bit of investigating suggests that the UIImages are not getting released and I have a memory leak. I am new to this so can someone tell me if this is the likely cause? If you could also tell me how to solve it then that would be amazing. The images are 480px x 480px and about 25kb each. My code is below... NSArray *rainImages = [NSArray arrayWithObjects: [UIImage imageNamed:@"rain-loop0001.png"], [UIImage imageNamed:@"rain-loop0002.png"], [UIImage imageNamed:@"rain-loop0003.png"], [UIImage imageNamed:@"rain-loop0004.png"], [UIImage imageNamed:@"rain-loop0005.png"], [UIImage imageNamed:@"rain-loop0006.png"], //more looping images [UIImage imageNamed:@"rain-loop0045.png"], [UIImage imageNamed:@"rain-loop0046.png"], [UIImage imageNamed:@"rain-loop0047.png"], [UIImage imageNamed:@"rain-loop0048.png"], [UIImage imageNamed:@"rain-loop0049.png"], [UIImage imageNamed:@"rain-loop0050.png"], nil]; rainImage.animationImages = rainImages; rainImage.animationDuration = 4.15/2; rainImage.animationRepeatCount = 0; [rainImage startAnimating]; [rainImage release]; Thanks

• make local only daemon listening on different interface (using iptables port forwarding)?

  - by UniIsland

  i have a daemon program which listens on 127.0.0.1:8000. i need to access it when i connect to my box with vpn. so i want it to listen on the ppp0 interface too. i've tried the "ssh -L" method. it works, but i don't think it's the right way to do that, having an extra ssh process running in the background. i tried the "netcat" method. it exits when the connection is closed. so not a valid way for "listening". i also tried several iptables rules. none of them worked. i'm not listing here all the rules i've used. iptables -A FORWARD -j ACCEPT iptables -t nat -A PREROUTING -i ppp+ -p tcp --dport 8000 -j DNAT --to-destination 127.0.0.1:8000 the above ruleset doesn't work. i have net.ipv4.ip_forward set to 1. anyone knows how to redirect traffic from ppp interface to lo? say, listen on "192.168.45.1:8000 (ppp0)" as well as "127.0.0.1:8000 (lo)" there's no need to alter the port. thanx

• Trying to calculate the 10001st prime number in Java.

  - by user247679

  Greetings. I am doing Problem 7 from Project Euler. What I am supposed to do is calculate the 10001st prime number. (A prime number being a number that is only divisible by itself and one.) Here is my current program: public class Problem7 { public static void main(String args []){ long numberOfPrimes = 0; long number = 2; while (numberOfPrimes < 10001){ if(isPrime(number)){ numberOfPrimes++; } number++; } System.out.println("10001st prime: "+ number); } public static boolean isPrime(long N) { if (N <= 1) return false; else return Prime(N,N-1); } public static boolean Prime(long X,long Y) { if (Y == 1) return true; else if (X % Y == 0) return false; else return Prime(X, Y-1); } } It works okay with finding, say the 100th prime number, but when I enter very large numbers such as 10001 it causes a stack overflow. Does anyone know of a way to fix this? Thanks for reading my problem!

• Codility-like sites for code golfs

  - by Adam Matan

  Hi, I've run into codility.com new cool service after listening to one of the recent stackoverflow.com podcasts. In short, it presents the user with a programming riddle to solve, within a given time frame. The user writes code in an online editor, and has the ability to run the program and view the standard output. After final submission, the user sees its final score and which tests failed him. Quoting Joel Spolsky: You are given a programming problem, you can do it in Java, C++, C#, C, Pascal, Python and PHP, which is pretty cool, and you have 30 minutes. And it gives you an editor in a webpage. And you've got to just start typing your code. And it's going to time you, basically you have to do it in a certain amount of time. And it actually runs your code and determines the performance characteristics of your code. It is intended for job interview screenings, but the idea seems very cool for code-golfs and for practicing new languages. Do you know if there's any proper open replacement? Adam

• No test coverage files generated for Unit Test bundle in Xcode

  - by John Gallagher

  The Problem I've got a Cocoa project on the desktop and I'm using Xcode 3.2.1 on Snow Leopard 10.6.2. I want to generate code coverage files for my Unit Test Target in Xcode. What I've Tried As articles like this one suggest, I've adjusted the build settings to: “Generate Test Coverage Files” checked “Instrument Program Flow” checked “-lgcov” added to “Other Linker Flags” I've also set the Run Script section of the test target to have the following: # Run the unit tests in this test bundle. "${SYSTEM_DEVELOPER_DIR}/Tools/RunUnitTests" # Run gcov on the framework getting tested if [ "${CONFIGURATION}" = 'Coverage' ]; then FRAMEWORK_NAME=LapsusInterpretationEngine FRAMEWORK_OBJ_DIR=${OBJROOT}/${FRAMEWORK_NAME}.build/${CONFIGURATION}/EngineTests.build/Objects-normal/${NATIVE_ARCH} mkdir -p coverage pushd coverage find ${OBJROOT} -name *.gcda -exec gcov -o ${FRAMEWORK_OBJ_DIR} {} \; popd fi Since my Framework name is LapsusInterpretationEngine but my target is named EngineTests, I put this directly into the FRAMEWORK_OBJ_DIR but this didn't seem to help. I've tried cleaning before building. I've made sure all the above build settings apply to both the Unit Test Target and the Application Target. What I Get No .gcda or .gcno files anywhere in the build directory I'm using. I point CoverStory to the Objects-normal directory in my builds folder and it complains that there's nothing there for it to read. I must be doing something really obvious wrong. Anyone any ideas? I have tried the "EngineTests.build" directory being ${FRAMEWORK_NAME} and this gives the same results.

• Create a VPN with Python

  - by user213060

  I want to make a device "tunnel box" that you plug an input ethernet line, and an output ethernet line, and all the traffic that goes through it gets modified in a special way. This is similar to how a firewall, IDS, VPN, or similar boxes are connected inline in a network. I think you can just assume that I am writing a custom VPN in Python for the purpose of this question: LAN computer <--\ LAN computer <---> [LAN switch] <--> ["tunnel box"] <--> [internet modem] <--> LAN computer <--/ My question is, what is a good way to program this "tunnel box" from python? My application needs to see TCP flows at the network layer, not as individual ethernet frames. Non-TCP/IP traffic such as ICPM and other types should just be passed through. Example Twisted-like Code for my "tunnel box" tunnel appliance: from my_code import special_data_conversion_function class StreamInterceptor(twisted.Protocol): def dataReceived(self,data): data=special_data_conversion_function(data) self.outbound_connection.send(data) My initial guesses: TUN/TAP with twisted.pair.tuntap.py - Problem: This seems to only work at the ethernet frame level, not like my example? Socks proxy - Problem: Not transparent as in my diagram. Programs have to be specifically setup for it. Thanks!

• Preventing Processes From Spawning Using .NET Code

  - by Matt

  I remember coming across an article on I think CodeProject quite some time ago regarding an antivirus or antimalware some guy was writing where he hooked into the Windows API to be able to catch whenever a new process was started and was prompting he user before allowing the process to start. I can no longer find the article, and would actually like to be able to implement something like this. Currently, we have a custom browser built on Gecko that we've integrated access restrictions to sites based on our internal employee security levels, etc. We prevent any other browser from running with a timer and a call to Process.GetProcessesByName() from a list of the browsers we don't allow. What we want to accomplish is, instead of just blocking these browsers, where there is a small delay between the other browser starting and it being killed by our service, we'd like to be able to display a dialog instead of the process launching at all, explaining that the program isn't in the allowed list. This way, we can generate a list of "allowed" processes and just block everything else (we haven't yet had a problem with outside apps being installed, but you can never be too careful). Unfortunately, we don't do much Windows API programming from C#, so I'm not sure where to begin looking for what calls we need to hook. Even just a starting point of what to read up on would be helpful.

• NSKeyedArchiver on NSArray has large size overhead

  - by redguy

  I'm using NSKeyedArchiver in Mac OS X program which generates data for iPhone application. I found out that by default, resulting archives are much bigger than I expected. Example: NSMutableArray * ar = [NSMutableArray arrayWithCapacity:10]; for (int i = 0; i < 100000; i++) { NSString * s = [NSString stringWithFormat:@"item%06d", i]; [ar addObject:s]; } [NSKeyedArchiver archiveRootObject:ar toFile: @"NSKeyedArchiver.test"]; This stores 10 * 100000 = 1M bytes of useful data, yet the size of the resulting file is almost three megabytes. The overhead seems to be growing with number of items in the array. In this case, for 1000 items, the file was about 22k. "file" reports that it is a "Apple binary property list" (not the XML format). Is there an simple way to prevent this huge overhead? I wanted to use the NSKeyedArchiver for the simplicity it provides. I can write data to my own, non-generic, binary format, but that's not very elegant. Also, aggregating the data into large chunks and feeding these to the NSKeyedArchiver should work, but again, that kinda beats the point of using simple&easy&ready to use archiver. Am I missing some method call or usage pattern that would reduce this overhead?
