• How to deal with MySQL Connector/ODBC error "Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'"

  - by user12653020

  I am sure many users run into a mysterious problem when perfectly working ODBC configurations started failing with errors like: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' The above error message might be preceded with something like [nxDc[yQ]. At the same time odbc.ini specifies in its DSN different SOCKET=/tmp/mysql.sock or a TCP connection SERVER=<remote_host_or_ip>. The question is, what had happened that the ODBC driver started to ignore the DSN options? The clue lies in the corrupted string [nxDc[yQ], which actually was [UnixODBC][MySQL] with each 2nd symbol removed. This is the case of bad conversion from SQLCHAR to SQLWCHAR. The UnixODBC driver manager took a single-byte character string from the client application and tried to convert it into the wide (multi-byte) characters for the Unicode version of MyODBC driver: Initially the piece of the connection string was represented by 1-byte chars like: [S][E][R][V][E][R][=][m][y][h][o][s][t][;] after the bad conversion to wide chars (commonly 2-byte UTF-16) [SE][RV][ER][=m][yh][os][t;] instead of [S\0][E\0][R\0][V\0][E\0][R\0][=\0][m\0][y\0][h\0][o\0][s\0][t\0][;\0] Naturally, the MyODBC driver could not parse the bad string and tried to use the default connection type (SOCKET) with the default value (/var/lib/mysql/mysql.sock) Now we know what happened, but why it happened? In most cases it happened because of using ODBCManageDataSourcesQ4 utility or its older analog ODBCConfig. When registering ODBC drivers they put lots of additional options and one of these options badly affects the UnixODBC driver manager itself. The solution is simple - remove or comment out the option in odbcinst.ini file (it is empty by default) set for the driver: [MySQL ODBC 5.2.6 Driver] Description    = Driver         = /home/dbs/myodbc526/lib/libmyodbc5w.so Driver64       = /home/dbs/myodbc526/lib/libmyodbc5w.so Setup          = /home/dbs/myodbc526/lib/libmyodbc5S.so Setup64        = /home/dbs/myodbc526/lib/libmyodbc5S.so UsageCount     = 1 CPTimeout      = 0 CPTimeToLive   = 0 IconvEncoding  =  # <--------- remove this line Trace          = TraceFile      = TraceLibrary   = After applying this simple solution (remove the line with IconvEncoding = ) everything came to normal. Prior to removing that line I tried putting different encoding names there, but the result was not good, so I really don't know how to properly use it. Unfortunately, UnixODBC manuals say nothing about it. Therefore, removing this option was the only way to get things done.

• Why C++ people loves multithreading when it comes to performances?

  - by user1849534

  I have a question, it's about why programmers seems to love concurrency and multi-threaded programs in general. I'm considering 2 main approach here: an async approach basically based on signals, or just an async approach as called by many papers and languages like the new C# 5.0 for example, and a "companion thread" that maanges the policy of your pipeline a concurrent approach or multi-threading approach I will just say that I'm thinking about the hardware here and the worst case scenario, and I have tested this 2 paradigms myself, the async paradigm is a winner at the point that I don't get why people 90% of the time talk about concurrency when they wont to speed up things or make a good use of their resources. I have tested multi-threaded programs and async program on an old machine with an Intel quad-core that doesn't offer a memory controller inside the CPU, the memory is managed entirely by the motherboard, well in this case performances are horrible with a multi-threaded application, even a relatively low number of threads like 3-4-5 can be a problem, the application is unresponsive and is just slow and unpleasant. A good async approach is, on the other hand, probably not faster but it's not worst either, my application just waits for the result and doesn't hangs, it's responsive and there is a much better scaling going on. I have also discovered that a context change in the threading world it's not that cheap in real world scenario, it's infact quite expensive especially when you have more than 2 threads that need to cycle and swap among each other to be computed. On modern CPUs the situation it's not really that different, the memory controller it's integrated but my point is that an x86 CPUs is basically a serial machine and the memory controller works the same way as with the old machine with an external memory controller on the motherboard. The context switch is still a relevant cost in my application and the fact that the memory controller it's integrated or that the newer CPU have more than 2 core it's not bargain for me. For what i have experienced the concurrent approach is good in theory but not that good in practice, with the memory model imposed by the hardware, it's hard to make a good use of this paradigm, also it introduces a lot of issues ranging from the use of my data structures to the join of multiple threads. Also both paradigms do not offer any security abut when the task or the job will be done in a certain point in time, making them really similar from a functional point of view. According to the X86 memory model, why the majority of people suggest to use concurrency with C++ and not just an async aproach ? Also why not considering the worst case scenario of a computer where the context switch is probably more expensive than the computation itself ?

• Google Chrome - Issues with download dialogs using BinaryWrite

  - by Mila

  Hello, I have an empty ASP .NET page with the code behind to support downloading of PDF files. The page is called from a link-like web control that has NavigateUrl set to this page. In short, I am using the following for streaming: Response.Buffer = false; Response.ClearHeaders(); Response.ContentType = "application/x-pdf"; Response.AddHeader("Content-Disposition","attachment; filename="MyPDFFile.pdf"); byte[] binary = (dataReaderRemote[DataPDFFieldName]) as byte[]; //dataReaderRemote[DataPDFFieldName] has previously retrieved data if (binary != null) { MemoryStream memoryStream = new MemoryStream(binary); int sizeToWrite = CHUNKSIZE; //CHUNKSIZE=1024 for (int i = 0; i < binary.GetUpperBound(0) - 1; i = i + CHUNKSIZE) { if (!Response.IsClientConnected) return; if (i + CHUNKSIZE >= binary.Length) sizeToWrite = binary.Length - i; byte[] chunk = new byte[sizeToWrite]; memoryStream.Read(chunk, 0, sizeToWrite); Response.BinaryWrite(chunk); Response.Flush(); } } Response.Close(); IE as well as Firefox bring the download prompt window asking you whether you wish to open or save the file, while the user remains on the same page containing the link. However, Google Chrome opens a new blank tab and downloads the file automatically. Is there any way to prevent Chrome from opening the extra blank and therefore useless tab? I am using the Google Chrome version 5.0.375.55 (Official Build 47796) on Windows XP. Thanks in advance! Mila

• MySQL Master-Master w/ multiple read slave cost effective setup in AWS

  - by Ross

  I've been evaluating Amazon Web Services RDS for MySQL and costing out potential scenarios involving a simple multi-AZ deployment read/write setup vs. a multi-AZ deployment mysql master (hot-standby) with additional read-only slaves. the issue I'm trying to cost-optimize includes their reserved instance vs on-demand instances. Situation 1: purchase reserved multi-az setup for Extra-large-hi-mem(17GB RAM) instance for $5200/yr and have my application query the master all the time. the problem is, if I don't need all the resources of the (17GB RAM) all the time and therefore, especially not a hot-standby, what alternatives for savings can a better topology create, like potentially situation 2 below: Situation 2: purchase reserved multi-az setup using smaller master instances than above for the master-master hot-standby to receive the writes only. Then create and load balance several read-only slaves off the master and add/remove and/or scale up/down the read slaves based on demand. This might only cost $1000 + the on-demand usage of the read slaves. My thinking is, if I have a variable read-intensive application load, with low write load, the single level topology in situation 1 means I'm paying for a lot of resources at the write level of topology when I don't need them there. My hope is that situation 2 can yield cost savings from smaller reserved instances on the master-master resource level allowing me to scale up and down and/or out on the read-level according to demand as needed. Does anyone see a downside to doing this or know of some reason this isn't possible with RDS? Any other thoughts or advice always welcome of course. Thanks in advance, R

• Java Port Socket Programming Error

  - by atrus-darkstone

  Hi- I have been working on a java client-server program using port sockets. The goal of this program is for the client to take a screenshot of the machine it is running on, break the RGB info of this image down into integers and arrays, then send this info over to the server, where it is reconstructed into a new image file. However, when I run the program I am experiencing the following two bugs: The first number recieved by the server, no matter what its value is according to the client, is always 49. The client only sends(or the server only receives?) the first value, then the program hangs forever. Any ideas as to why this is happening, and what I can do to fix it? The code for both client and server is below. Thanks!

• Weekend reading: Microsoft/Oracle and SkyDrive based code-editor

  - by jamiet

  A couple of news item caught my eye this weekend that I think are worthy of comment. Microsoft/Oracle partnership to be announced tomorrow (24/06/2013) According to many news site Microsoft and Oracle are about to announce a partnership (Oracle set for major Microsoft, Salesforce, Netsuite partnerships) and they all seem to be assuming that it will be something to do with “the cloud”. I wouldn’t disagree with that assessment, Microsoft are heavily pushing Azure and Oracle seem (to me anyway) to be rather lagging behind in the cloud game. More specifically folks seem to be assuming that Oracle’s forthcoming 12c database release will be offered on Azure. I did a bit of reading about Oracle 12c and one of its key pillars appears to be that it supports multi-tenant topologies and multi-tenancy is a common usage scenario for databases in the cloud. I’m left wondering then, if Microsoft are willing to push a rival’s multi-tenant solution what is happening to its own cloud-based multi-tenant offering – SQL Azure Federations. We haven’t heard anything about federations for what now seems to be a long time and moreover the main Program Manager behind the technology, Cihan Biyikoglu, recently left Microsoft to join Twitter. Furthermore, a Principle Architect for SQL Server, Conor Cunningham, recently presented the opening keynote at SQLBits 11 where he talked about multi-tenant solutions on SQL Azure and not once did he mention federations. All in all I don’t have a warm fuzzy feeling about the future of SQL Azure Federations so I hope that that question gets asked at some point following the Microsoft/Oracle announcement. Text Editor on SkyDrive with coding-specific features Liveside.net got a bit of a scoop this weekend with the news (Exclusive: SkyDrive.com to get web-based text file editing features) that Microsoft’s consumer-facing file storage service is going to get a new feature – a web-based code editor. Here’s Liveside’s screenshot: I’ve long had a passing interest in online code editors, indeed back in December 2009 I wondered out loud on this blog site: I started to wonder when the development tools that we use would also become cloud-based. After all, if we’re using cloud-based services does it not make sense to have cloud-based tools that work with them? I think it does. Project Houston Since then the world has moved on. Cloud 9 IDE (https://c9.io/) have blazed a trail in the fledgling world of online code editors and I have been wondering when Microsoft were going to start playing catch-up. I had no doubt that an online code editor was in Microsoft’s future; its an obvious future direction, why would I want to have to download and install a bloated text editor (which, arguably, is exactly what Visual Studio amounts to) and have to continually update it when I can simply open a web browser and have ready access to all of my code from wherever I am. There are signs that Microsoft is already making moves in this direction, after all the URL for their new offering Team Foundation Service doesn’t mention TFS at all – my own personalised URL for Team Foundation Service is http://jamiet.visualstudio.com – using “Visual Studio” as the domain name for a service that isn’t strictly speaking part of Visual Studio leads me to think that there’s a much bigger play here and that one day http://visualstudio.com will house an online code editor. With that in mind then I find Liveside’s revelation rather intriguing, why would a code editing tool show up in Skydrive? Perhaps SkyDrive is going to get integrated more tightly into TFS, I’m very interested to see where this goes. The larger question playing on my mind though is whether an online code editor from Microsoft will support SQL Server developers. I have opined before (see The SQL developer gap) about the shoddy treatment that SQL Server developers have to experience from Microsoft and I haven’t seen any change in Microsoft’s attitude in the three and a half years since I wrote that post. I’m constantly bewildered by the lack of investment in SQL Server developer productivity compared to the riches that are lavished upon our appdev brethren. When you consider that SQL Server is Microsoft’s third biggest revenue stream it is, frankly, rather insulting. SSDT was a step in the right direction but the hushed noises I hear coming out of Microsoft of late in regard to SSDT don’t bode fantastically well for its future. So, will an online code editor from Microsoft support T-SQL development? I have to assume not given the paucity of investment on us lowly SQL Server developers over the last few years, but I live in hope! Your thoughts in the comments section please. I would be very interested in reading them. @Jamiet

• Working with packed dates in SSIS

  - by Jim Giercyk

  One of the challenges recently thrown my way was to read an EBCDIC flat file, decode packed dates, and insert the dates into a SQL table.  For those unfamiliar with packed data, it is a way to store data at the nibble level (half a byte), and was often used by mainframe programmers to conserve storage space.  In the case of my input file, the dates were 2 bytes long and  represented the number of days that have past since 01/01/1950.  My first thought was, in the words of Scooby, Hmmmmph?  But, I love a good challenge, so I dove in. Reading in the flat file was rather simple.  The only difference between reading an EBCDIC and an ASCII file is the Code Page option in the connection manager.  In my case, I needed to use Code Page 1140 for EBCDIC (I could have also used Code Page 37).       Once the code page is set correctly, SSIS can understand what it is reading and it will convert the output to the default code page, 1252.  However, packed data is either unreadable or produces non-alphabetic characters, as we can see in the preview window.   Column 1 is actually the packed date, columns 0 and 2 are the values in the rest of the file.  We are only interested in Column 1, which is a 2 byte field representing a packed date.  We know that 2 bytes of packed data can be stored in 1 byte of character data, so we are working with 4 packed digits in 2 character bytes.  If you are confused, stay tuned….this will make sense in a minute.   Right-click on your Flat File Source shape and select “Show Advanced Editor”. Here is where the magic begins. By changing the properties of the output columns, we can access the packed digits from each byte. By default, the Output Column data type is DT_STR. Since we want to look at the bytes individually and not the entire string, change the data type to DT_BYTES. Next, and most important, set UseBinaryFormat to TRUE. This will write the HEX VALUES of the output string instead of writing the character values.  Now we are getting somewhere! Next, you will need to use a Data Conversion shape in your Data Flow to transform the 2 position byte stream to a 4 position Unicode string containing the packed data.  You need the string to be 4 bytes long because it will contain the 4 packed digits.  Here is what that should look like in the Data Conversion shape: Direct the output of your data flow to a test table or file to see the results.  In my case, I created a test table.  The results looked like this:     Hold on a second!  That doesn't look like a date at all.  No, of course not.  It is a hex number which represents the days which have passed between 01/01/1950 and the date.  We have to convert the Hex value to a decimal value, and use the DATEADD function to get a date value.  Luckily, I have created a function to convert Hex to Decimal:   -- ============================================= -- Author:        Jim Giercyk -- Create date: March, 2012 -- Description:    Converts a Hex string to a decimal value -- ============================================= CREATE FUNCTION [dbo].[ftn_HexToDec] (     @hexValue NVARCHAR(6) ) RETURNS DECIMAL AS BEGIN     -- Declare the return variable here DECLARE @decValue DECIMAL IF @hexValue LIKE '0x%' SET @hexValue = SUBSTRING(@hexValue,3,4) DECLARE @decTab TABLE ( decPos1 VARCHAR(2), decPos2 VARCHAR(2), decPos3 VARCHAR(2), decPos4 VARCHAR(2) ) DECLARE @pos1 VARCHAR(1) = SUBSTRING(@hexValue,1,1) DECLARE @pos2 VARCHAR(1) = SUBSTRING(@hexValue,2,1) DECLARE @pos3 VARCHAR(1) = SUBSTRING(@hexValue,3,1) DECLARE @pos4 VARCHAR(1) = SUBSTRING(@hexValue,4,1) INSERT @decTab VALUES (CASE               WHEN @pos1 = 'A' THEN '10'                 WHEN @pos1 = 'B' THEN '11'               WHEN @pos1 = 'C' THEN '12'               WHEN @pos1 = 'D' THEN '13'               WHEN @pos1 = 'E' THEN '14'               WHEN @pos1 = 'F' THEN '15'               ELSE @pos1              END, CASE               WHEN @pos2 = 'A' THEN '10'                 WHEN @pos2 = 'B' THEN '11'               WHEN @pos2 = 'C' THEN '12'               WHEN @pos2 = 'D' THEN '13'               WHEN @pos2 = 'E' THEN '14'               WHEN @pos2 = 'F' THEN '15'               ELSE @pos2              END, CASE               WHEN @pos3 = 'A' THEN '10'                 WHEN @pos3 = 'B' THEN '11'               WHEN @pos3 = 'C' THEN '12'               WHEN @pos3 = 'D' THEN '13'               WHEN @pos3 = 'E' THEN '14'               WHEN @pos3 = 'F' THEN '15'               ELSE @pos3              END, CASE               WHEN @pos4 = 'A' THEN '10'                 WHEN @pos4 = 'B' THEN '11'               WHEN @pos4 = 'C' THEN '12'               WHEN @pos4 = 'D' THEN '13'               WHEN @pos4 = 'E' THEN '14'               WHEN @pos4 = 'F' THEN '15'               ELSE @pos4              END) SET @decValue = (CONVERT(INT,(SELECT decPos4 FROM @decTab)))         +                 (CONVERT(INT,(SELECT decPos3 FROM @decTab))*16)      +                 (CONVERT(INT,(SELECT decPos2 FROM @decTab))*(16*16)) +                 (CONVERT(INT,(SELECT decPos1 FROM @decTab))*(16*16*16))     RETURN @decValue END GO     Making use of the function, I found the decimal conversion, added that number of days to 01/01/1950 and FINALLY arrived at my “unpacked relative date”.  Here is the query I used to retrieve the formatted date, and the result set which was returned: SELECT [packedDate] AS 'Hex Value',        dbo.ftn_HexToDec([packedDate]) AS 'Decimal Value',        CONVERT(DATE,DATEADD(day,dbo.ftn_HexToDec([packedDate]),'01/01/1950'),101) AS 'Relative String Date'   FROM [dbo].[Output Table]         This technique can be used any time you need to retrieve the hex value of a character string in SSIS.  The date example may be a bit difficult to understand at first, but with SSIS becoming the preferred tool for enterprise level integration for many companies, there is no doubt that developers will encounter these types of requirements with regularity in the future. Please feel free to contact me if you have any questions.

• Wisdom of merging 100s of Oracle instances into one instance

  - by hoytster

  Our application runs on the web, is mostly an inquiry tool, does some transactions. We host the Oracle database. The app has always had a different instance of Oracle for each customer. A customer is a company which pays us to provide our service to the company's employees, typically 10,000-25,000 employees per customer. We do a major release every few years, and migrating to that new release is challenging: we might have a team at the customer site for a couple weeks, explaining new functionality and setting up the driving data to suit that customer. We're considering going multi-client, putting all our customers into a single shared Oracle 11g instance on a big honkin' Windows Server 2008 server -- in order to reduce costs. I'm wondering if that's advisable. There are some advantages to having separate instances for each customer. Tell me if these are bogus, please. In my rough guess about decreasing importance: Our customers MyCorp and YourCo can be migrated separately when breaking changes are made to the schema. (With multi-client, we'd be migrating 300+ customers overnight!?!) MyCorp's data can be easily backed up and (!!!) restored, without affecting other customers. MyCorp's data is securely separated from their competitor YourCo's data, without depending on developers to get the code right and/or DBAs getting the configuration right. Performance is better because the database is smaller (5,000 vs 2,000,000 rows in ~50 tables). If MyCorp's offices are (mostly) in just one region, then the MyCorp's instance can be geographically co-located there, so network lag doesn't hurt performance. We can provide better service to global clients, for the same reason. In MyCorp wants to take their database in-house, then we can easily export their instance, to get MyCorp their data. Load-balancing is easier because instances can be placed on different servers (this is with a web farm). When a DEV or QA instance is needed, it's easier to clone the real instance and anonymize the data, because there's much less data. Because they're small enough, developers can have their own instance running locally, so they can work on code while waiting at the airport and while in-flight, without fighting VPN hassles. Q1: What are other advantages of separate instances? We are contemplating changing the database schema and merging all of our customers into one Oracle instance, running on one hefty server. Here are advantages of the multi-client instance approach, most important first (my WAG). Please snipe if these are bogus: Less work for the DBAs, since they only need to maintain one instance instead of hundreds. Less DBA work translates to cheaper, our main motive for this change. With just one instance, the DBAs can do a better job of optimizing performance. They'll have time to add appropriate indexes and review our SQL. It will be easier for developers to debug & enhance the application, because there is only one schema and one app (there might be dozens of schema versions if there are hundreds of instances, with a different version of the app for each version of the schema). This reduces costs too. The alternative is having to start every debug session with (1) What version is this customer running and (2) Let's struggle to recreate the corresponding development environment, code and database. (We need a Virtual Machine that includes the code AND database instance for each patch and release!) Licensing Oracle is cheaper because it's priced per server irrespective of heft (or something -- I don't know anything about the subject). The database becomes a viable persistent store for web session data, because there is just one instance. Some database operations are easier with one multi-client instance, like finding a participant when they're hazy about which customer they (or their spouse, maybe) works for: all the names are in one table. Reporting across customers is straightforward. Q2: What are other advantages of having multiple clients in one instance? Q3: Which approach do you think is better (why)? Instance per customer, or all customers in one instance? I'm concerned that having one multi-client instance makes migration near-impossible, and that's a deal killer... ... unless there is a compromise solution like having two multi-client instances, the old and the new. In that case case, we would design cross-instance solutions for finding participants, reporting, etc. so customers could go from one multi-client instance to the next without anything breaking. THANKS SO MUCH for your collective advice! This issue is beyond me -- but not beyond the collective you. :) Hoytster

• How to match ColdFusion encryption with Java 1.4.2?

  - by JohnTheBarber

  * sweet - thanks to Edward Smith for the CF Technote that indicated the key from ColdFusion was Base64 encoded. See generateKey() for the 'fix' My task is to use Java 1.4.2 to match the results a given ColdFusion code sample for encryption. Known/given values: A 24-byte key A 16-byte salt (IVorSalt) Encoding is Hex Encryption algorithm is AES/CBC/PKCS5Padding A sample clear-text value The encrypted value of the sample clear-text after going through the ColdFusion code Assumptions: Number of iterations not specified in the ColdFusion code so I assume only one iteration 24-byte key so I assume 192-bit encryption Given/working ColdFusion encryption code sample: <cfset ThisSalt = "16byte-salt-here"> <cfset ThisAlgorithm = "AES/CBC/PKCS5Padding"> <cfset ThisKey = "a-24byte-key-string-here"> <cfset thisAdjustedNow = now()> <cfset ThisDateTimeVar = DateFormat( thisAdjustedNow , "yyyymmdd" )> <cfset ThisDateTimeVar = ThisDateTimeVar & TimeFormat( thisAdjustedNow , "HHmmss" )> <cfset ThisTAID = ThisDateTimeVar & "|" & someOtherData> <cfset ThisTAIDEnc = Encrypt( ThisTAID , ThisKey , ThisAlgorithm , "Hex" , ThisSalt)> My Java 1.4.2 encryption/decryption code swag: package so.example; import java.security.*; import javax.crypto.Cipher; import javax.crypto.spec.IvParameterSpec; import javax.crypto.spec.SecretKeySpec; import org.apache.commons.codec.binary.*; public class SO_AES192 { private static final String _AES = "AES"; private static final String _AES_CBC_PKCS5Padding = "AES/CBC/PKCS5Padding"; private static final String KEY_VALUE = "a-24byte-key-string-here"; private static final String SALT_VALUE = "16byte-salt-here"; private static final int ITERATIONS = 1; private static IvParameterSpec ivParameterSpec; public static String encryptHex(String value) throws Exception { Key key = generateKey(); Cipher c = Cipher.getInstance(_AES_CBC_PKCS5Padding); ivParameterSpec = new IvParameterSpec(SALT_VALUE.getBytes()); c.init(Cipher.ENCRYPT_MODE, key, ivParameterSpec); String valueToEncrypt = null; String eValue = value; for (int i = 0; i < ITERATIONS; i++) { // valueToEncrypt = SALT_VALUE + eValue; // pre-pend salt - Length > sample length valueToEncrypt = eValue; // don't pre-pend salt Length = sample length byte[] encValue = c.doFinal(valueToEncrypt.getBytes()); eValue = Hex.encodeHexString(encValue); } return eValue; } public static String decryptHex(String value) throws Exception { Key key = generateKey(); Cipher c = Cipher.getInstance(_AES_CBC_PKCS5Padding); ivParameterSpec = new IvParameterSpec(SALT_VALUE.getBytes()); c.init(Cipher.DECRYPT_MODE, key, ivParameterSpec); String dValue = null; char[] valueToDecrypt = value.toCharArray(); for (int i = 0; i < ITERATIONS; i++) { byte[] decordedValue = Hex.decodeHex(valueToDecrypt); byte[] decValue = c.doFinal(decordedValue); // dValue = new String(decValue).substring(SALT_VALUE.length()); // when salt is pre-pended dValue = new String(decValue); // when salt is not pre-pended valueToDecrypt = dValue.toCharArray(); } return dValue; } private static Key generateKey() throws Exception { // Key key = new SecretKeySpec(KEY_VALUE.getBytes(), _AES); // this was wrong Key key = new SecretKeySpec(new BASE64Decoder().decodeBuffer(keyValueString), _AES); // had to un-Base64 the 'known' 24-byte key. return key; } } I cannot create a matching encrypted value nor decrypt a given encrypted value. My guess is it's something to do with how I'm handling the initial vector/salt. I'm not very crypto-savvy but I'm thinking I should be able to take the sample clear-text and produce the same encrypted value in Java as ColdFusion produced. I am able to encrypt/decrypt my own data with my Java code (so I'm consistent) but I cannot match nor decrypt the ColdFusion sample encrypted value. I have access to a local webservice that can test the encrypted output. The given ColdFusion output sample passes/decrypts fine (of course). If I try to decrypt the same sample with my Java code (using the actual key and salt) I get a "Given final block not properly padded" error. I get the same net result when I pass my attempt at encryption (using the actual key and salt) to the test webservice. Any Ideas?

• How to compare a memory bits in C++?

  - by Trunet

  Hi, I need help with a memory bit comparison function. I bought a LED Matrix here with 4 x HT1632C chips and I'm using it on my arduino mega2560. There're no code available for this chipset(it's not the same as HT1632) and I'm writing on my own. I have a plot function that get x,y coordinates and a color and that pixel turn on. Only this is working perfectly. But I need more performance on my display so I tried to make a shadowRam variable that is a "copy" of my device memory. Before I plot anything on display it checks on shadowRam to see if it's really necessary to change that pixel. When I enabled this(getShadowRam) on plot function my display has some, just SOME(like 3 or 4 on entire display) ghost pixels(pixels that is not supposed to be turned on). If I just comment the prev_color if's on my plot function it works perfectly. Also, I'm cleaning my shadowRam array setting all matrix to zero. variables: #define BLACK 0 #define GREEN 1 #define RED 2 #define ORANGE 3 #define CHIP_MAX 8 byte shadowRam[63][CHIP_MAX-1] = {0}; getShadowRam function: byte HT1632C::getShadowRam(byte x, byte y) { byte addr, bitval, nChip; if (x>=32) { nChip = 3 + x/16 + (y>7?2:0); } else { nChip = 1 + x/16 + (y>7?2:0); } bitval = 8>>(y&3); x = x % 16; y = y % 8; addr = (x<<1) + (y>>2); if ((shadowRam[addr][nChip-1] & bitval) && (shadowRam[addr+32][nChip-1] & bitval)) { return ORANGE; } else if (shadowRam[addr][nChip-1] & bitval) { return GREEN; } else if (shadowRam[addr+32][nChip-1] & bitval) { return RED; } else { return BLACK; } } plot function: void HT1632C::plot (int x, int y, int color) { if (x<0 || x>X_MAX || y<0 || y>Y_MAX) return; if (color != BLACK && color != GREEN && color != RED && color != ORANGE) return; char addr, bitval; byte nChip; byte prev_color = HT1632C::getShadowRam(x,y); bitval = 8>>(y&3); if (x>=32) { nChip = 3 + x/16 + (y>7?2:0); } else { nChip = 1 + x/16 + (y>7?2:0); } x = x % 16; y = y % 8; addr = (x<<1) + (y>>2); switch(color) { case BLACK: if (prev_color != BLACK) { // compare with memory to only set if pixel is other color // clear the bit in both planes; shadowRam[addr][nChip-1] &= ~bitval; HT1632C::sendData(nChip, addr, shadowRam[addr][nChip-1]); shadowRam[addr+32][nChip-1] &= ~bitval; HT1632C::sendData(nChip, addr+32, shadowRam[addr+32][nChip-1]); } break; case GREEN: if (prev_color != GREEN) { // compare with memory to only set if pixel is other color // set the bit in the green plane and clear the bit in the red plane; shadowRam[addr][nChip-1] |= bitval; HT1632C::sendData(nChip, addr, shadowRam[addr][nChip-1]); shadowRam[addr+32][nChip-1] &= ~bitval; HT1632C::sendData(nChip, addr+32, shadowRam[addr+32][nChip-1]); } break; case RED: if (prev_color != RED) { // compare with memory to only set if pixel is other color // clear the bit in green plane and set the bit in the red plane; shadowRam[addr][nChip-1] &= ~bitval; HT1632C::sendData(nChip, addr, shadowRam[addr][nChip-1]); shadowRam[addr+32][nChip-1] |= bitval; HT1632C::sendData(nChip, addr+32, shadowRam[addr+32][nChip-1]); } break; case ORANGE: if (prev_color != ORANGE) { // compare with memory to only set if pixel is other color // set the bit in both the green and red planes; shadowRam[addr][nChip-1] |= bitval; HT1632C::sendData(nChip, addr, shadowRam[addr][nChip-1]); shadowRam[addr+32][nChip-1] |= bitval; HT1632C::sendData(nChip, addr+32, shadowRam[addr+32][nChip-1]); } break; } } If helps: The datasheet of board I'm using. On page 7 has the memory mapping I'm using. Also, I have a video of display working.

• Using C# to detect whether a filename character is considered international

  - by Morten Mertner

  I've written a small console application (source below) to locate and optionally rename files containing international characters, as they are a source of constant pain with most source control systems (some background on this below). The code I'm using has a simple dictionary with characters to look for and replace (and nukes every other character that uses more than one byte of storage), but it feels very hackish. What's the right way to (a) find out whether a character is international? and (b) what the best ASCII substitution character would be? Let me provide some background information on why this is needed. It so happens that the danish Å character has two different encodings in UTF-8, both representing the same symbol. These are known as NFC and NFD encodings. Windows and Linux will create NFC encoding by default but respect whatever encoding it is given. Mac will convert all names (when saving to a HFS+ partition) to NFD and therefore returns a different byte stream for the name of a file created on Windows. This effectively breaks Subversion, Git and lots of other utilities that don't care to properly handle this scenario. I'm currently evaluating Mercurial, which turns out to be even worse at handling international characters.. being fairly tired of these problems, either source control or the international character would have to go, and so here we are. My current implementation: public class Checker { private Dictionary<char, string> internationals = new Dictionary<char, string>(); private List<char> keep = new List<char>(); private List<char> seen = new List<char>(); public Checker() { internationals.Add( 'æ', "ae" ); internationals.Add( 'ø', "oe" ); internationals.Add( 'å', "aa" ); internationals.Add( 'Æ', "Ae" ); internationals.Add( 'Ø', "Oe" ); internationals.Add( 'Å', "Aa" ); internationals.Add( 'ö', "o" ); internationals.Add( 'ü', "u" ); internationals.Add( 'ä', "a" ); internationals.Add( 'é', "e" ); internationals.Add( 'è', "e" ); internationals.Add( 'ê', "e" ); internationals.Add( '¦', "" ); internationals.Add( 'Ã', "" ); internationals.Add( '©', "" ); internationals.Add( ' ', "" ); internationals.Add( '§', "" ); internationals.Add( '¡', "" ); internationals.Add( '³', "" ); internationals.Add( '­', "" ); internationals.Add( 'º', "" ); internationals.Add( '«', "-" ); internationals.Add( '»', "-" ); internationals.Add( '´', "'" ); internationals.Add( '`', "'" ); internationals.Add( '"', "'" ); internationals.Add( Encoding.UTF8.GetString( new byte[] { 226, 128, 147 } )[ 0 ], "-" ); internationals.Add( Encoding.UTF8.GetString( new byte[] { 226, 128, 148 } )[ 0 ], "-" ); internationals.Add( Encoding.UTF8.GetString( new byte[] { 226, 128, 153 } )[ 0 ], "'" ); internationals.Add( Encoding.UTF8.GetString( new byte[] { 226, 128, 166 } )[ 0 ], "." ); keep.Add( '-' ); keep.Add( '=' ); keep.Add( '\'' ); keep.Add( '.' ); } public bool IsInternationalCharacter( char c ) { var s = c.ToString(); byte[] bytes = Encoding.UTF8.GetBytes( s ); if( bytes.Length > 1 && ! internationals.ContainsKey( c ) && ! seen.Contains( c ) ) { Console.WriteLine( "X '{0}' ({1})", c, string.Join( ",", bytes ) ); seen.Add( c ); if( ! keep.Contains( c ) ) { internationals[ c ] = ""; } } return internationals.ContainsKey( c ); } public bool HasInternationalCharactersInName( string name, out string safeName ) { StringBuilder sb = new StringBuilder(); Array.ForEach( name.ToCharArray(), c => sb.Append( IsInternationalCharacter( c ) ? internationals[ c ] : c.ToString() ) ); int length = sb.Length; sb.Replace( " ", " " ); while( sb.Length != length ) { sb.Replace( " ", " " ); } safeName = sb.ToString().Trim(); string namePart = Path.GetFileNameWithoutExtension( safeName ); if( namePart.EndsWith( "." ) ) safeName = namePart.Substring( 0, namePart.Length - 1 ) + Path.GetExtension( safeName ); return name != safeName; } } And this would be invoked like this: FileInfo file = new File( "Århus.txt" ); string safeName; if( checker.HasInternationalCharactersInName( file.Name, out safeName ) ) { // rename file }

• Android: OutOfMemoryError while uploading video...

  - by AP257

  Hi all, I have the same problem as described here, but I will supply a few more details. While trying to upload a video in Android, I'm reading it into memory, and if the video is large I get an OutOfMemoryError. Here's my code: // get bytestream to upload videoByteArray = getBytesFromFile(cR, fileUriString); public static byte[] getBytesFromFile(ContentResolver cR, String fileUriString) throws IOException { Uri tempuri = Uri.parse(fileUriString); InputStream is = cR.openInputStream(tempuri); byte[] b3 = readBytes(is); is.close(); return b3; } public static byte[] readBytes(InputStream inputStream) throws IOException { ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream(); // this is storage overwritten on each iteration with bytes int bufferSize = 1024; byte[] buffer = new byte[bufferSize]; int len = 0; while ((len = inputStream.read(buffer)) != -1) { byteBuffer.write(buffer, 0, len); } return byteBuffer.toByteArray(); } And here's the traceback (the error is thrown on the byteBuffer.write(buffer, 0, len) line): 04-08 11:56:20.456: ERROR/dalvikvm-heap(6088): Out of memory on a 16775184-byte allocation. 04-08 11:56:20.456: INFO/dalvikvm(6088): "IntentService[UploadService]" prio=5 tid=17 RUNNABLE 04-08 11:56:20.456: INFO/dalvikvm(6088): | group="main" sCount=0 dsCount=0 s=N obj=0x449a3cf0 self=0x38d410 04-08 11:56:20.456: INFO/dalvikvm(6088): | sysTid=6119 nice=0 sched=0/0 cgrp=default handle=4010416 04-08 11:56:20.456: INFO/dalvikvm(6088): at java.io.ByteArrayOutputStream.expand(ByteArrayOutputStream.java:~93) 04-08 11:56:20.456: INFO/dalvikvm(6088): at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:218) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.readBytes(UploadService.java:199) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.getBytesFromFile(UploadService.java:182) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.doUploadinBackground(UploadService.java:118) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.onHandleIntent(UploadService.java:85) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:30) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.Handler.dispatchMessage(Handler.java:99) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.Looper.loop(Looper.java:123) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.HandlerThread.run(HandlerThread.java:60) 04-08 11:56:20.467: WARN/dalvikvm(6088): threadid=17: thread exiting with uncaught exception (group=0x4001b180) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): Uncaught handler: thread IntentService[UploadService] exiting due to uncaught exception 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): java.lang.OutOfMemoryError 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at java.io.ByteArrayOutputStream.expand(ByteArrayOutputStream.java:93) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:218) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.readBytes(UploadService.java:199) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.getBytesFromFile(UploadService.java:182) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.doUploadinBackground(UploadService.java:118) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.onHandleIntent(UploadService.java:85) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:30) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.Handler.dispatchMessage(Handler.java:99) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.Looper.loop(Looper.java:123) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.HandlerThread.run(HandlerThread.java:60) 04-08 11:56:20.496: INFO/Process(4657): Sending signal.

• Microsoft SyncFramework - Sync different tables into one

  - by evnu

  Hello, we are trying to get the Microsoft SyncFramework running in our application to synchronize an oracle db with a mobile device. Problem The queries that we need to gather the data on the oracle db take much time (and we haven't found a way to speed them up yet), so we try to split them up in as much portions as possible. One big part of the whole problem is, that we need different information out of one big table, that bloats a query if combined. Unfortunately, the SyncFramework allows only one TableAdapter per SyncTable. Now this is a problem for our application: If we were able to use more than one TableAdapter per SyncTable, we could easily spread the queries in a more efficient way. Using one query per Table which combines all the needed data takes way too much time. Ideas I thought of creating different TableAdapters for each one of the required queries and then merge the resulting datasets afterwards (preferably on the server). This seems to work, but is a rather awkward solution. Does someone of you know a better solution? Or do you have some ideas that could help? Thanks in advance, evnu EDIT: So, I implemented the merge solution. If you are interested, take a look at the following code. I'll give more details if there are questions. <WebMethod()> _ Public Function GetChanges(ByVal groupMetadata As SyncGroupMetadata, ByVal syncSession As SyncSession) As SyncContext Dim stream As MemoryStream Dim format As BinaryFormatter = New BinaryFormatter Dim anchors As Dictionary(Of String, Byte()) ' keep track of the tables that will be updated Dim addTables As Dictionary(Of String, List(Of SyncTableMetadata)) = New Dictionary(Of String, List(Of SyncTableMetadata)) ' list of all present anchors Dim allAnchors As Dictionary(Of String, Byte()) = New Dictionary(Of String, Byte()) ' fill allAnchors - deserialize all given anchors For Each Table As SyncTableMetadata In groupMetadata.TablesMetadata If Table.LastReceivedAnchor Is Nothing Or Table.LastReceivedAnchor.IsNull Then Continue For stream = New MemoryStream(Table.LastReceivedAnchor.Anchor) anchors = format.Deserialize(stream) For Each item As KeyValuePair(Of String, Byte()) In anchors allAnchors.Add(item.Key, item.Value) Next stream.Dispose() Next For Each Table As SyncTableMetadata In groupMetadata.TablesMetadata If allAnchors.ContainsKey(Table.TableName) Then Table.LastReceivedAnchor.Anchor = allAnchors(Table.TableName) End If Dim addSyncTables As List(Of SyncTableMetadata) If syncSession.SyncParameters.Contains(Table.TableName) Then Dim tableNames() As String = syncSession.SyncParameters(Table.TableName).Value.ToString.Split(":") addSyncTables = New List(Of SyncTableMetadata) For Each tableName As String In tableNames Dim newSynctable As SyncTableMetadata = New SyncTableMetadata newSynctable.TableName = tableName If allAnchors.ContainsKey(tableName) Then Dim anker As SyncAnchor = New SyncAnchor(allAnchors(tableName)) newSynctable.LastReceivedAnchor = anker Else newSynctable.LastReceivedAnchor = Nothing End If newSynctable.SyncDirection = Table.SyncDirection addSyncTables.Add(newSynctable) Next addTables.Add(Table.TableName, addSyncTables) End If Next ' add the newly created synctables For Each item As KeyValuePair(Of String, List(Of SyncTableMetadata)) In addTables For Each Table As SyncTableMetadata In item.Value groupMetadata.TablesMetadata.Add(Table) Next Next ' fire queries Dim context As SyncContext = servSyncProvider.GetChanges(groupMetadata, syncSession) ' merge resulting datasets For Each item As KeyValuePair(Of String, List(Of SyncTableMetadata)) In addTables For Each Table As SyncTableMetadata In item.Value If context.DataSet.Tables.Contains(Table.TableName) Then If Not context.DataSet.Tables.Contains(item.Key) Then Dim tmp As DataTable = context.DataSet.Tables(Table.TableName).Copy tmp.TableName = item.Key context.DataSet.Tables.Add(tmp) Else context.DataSet.Tables(item.Key).Merge(context.DataSet.Tables(Table.TableName)) context.DataSet.Tables.Remove(Table.TableName) End If End If Next Next ' create new anchors Dim allAnchorsDict As Dictionary(Of String, Byte()) = New Dictionary(Of String, Byte()) For Each Table As SyncTableMetadata In groupMetadata.TablesMetadata allAnchorsDict.Add(Table.TableName, context.NewAnchor.Anchor) Next stream = New MemoryStream format.Serialize(stream, allAnchorsDict) context.NewAnchor.Anchor = stream.ToArray stream.Dispose() Return context End Function

• Creating a GraphicsPath from a semi-transparent bitmap

  - by Moozhe

  I want to create a GraphicsPath and a list of Points to form the outline of the non-transparent area of a bitmap. If needed, I can guarantee that each image has only one solid collection of nontransparent pixels. So for example, I should be able to record the points either clockwise or counter-clockwise along the edge of the pixels and perform a full closed loop. The speed of this algorithm is not important. However, the efficiency of the resulting points is semi-important if I can skip some points to reduce in a smaller and less complex GraphicsPath. I will list my current code below which works perfectly with most images. However, some images which are more complex end up with paths which seem to connect in the wrong order. I think I know why this occurs, but I can't come up with a solution. public static Point[] GetOutlinePoints(Bitmap image) { List<Point> outlinePoints = new List<Point>(); BitmapData bitmapData = image.LockBits(new Rectangle(0, 0, image.Width, image.Height), ImageLockMode.ReadOnly, PixelFormat.Format32bppArgb); byte[] originalBytes = new byte[image.Width * image.Height * 4]; Marshal.Copy(bitmapData.Scan0, originalBytes, 0, originalBytes.Length); for (int x = 0; x < bitmapData.Width; x++) { for (int y = 0; y < bitmapData.Height; y++) { byte alpha = originalBytes[y * bitmapData.Stride + 4 * x + 3]; if (alpha != 0) { Point p = new Point(x, y); if (!ContainsPoint(outlinePoints, p)) outlinePoints.Add(p); break; } } } for (int y = 0; y < bitmapData.Height; y++) { for (int x = bitmapData.Width - 1; x >= 0; x--) { byte alpha = originalBytes[y * bitmapData.Stride + 4 * x + 3]; if (alpha != 0) { Point p = new Point(x, y); if (!ContainsPoint(outlinePoints, p)) outlinePoints.Add(p); break; } } } for (int x = bitmapData.Width - 1; x >= 0; x--) { for (int y = bitmapData.Height - 1; y >= 0; y--) { byte alpha = originalBytes[y * bitmapData.Stride + 4 * x + 3]; if (alpha != 0) { Point p = new Point(x, y); if (!ContainsPoint(outlinePoints, p)) outlinePoints.Add(p); break; } } } for (int y = bitmapData.Height - 1; y >= 0; y--) { for (int x = 0; x < bitmapData.Width; x++) { byte alpha = originalBytes[y * bitmapData.Stride + 4 * x + 3]; if (alpha != 0) { Point p = new Point(x, y); if (!ContainsPoint(outlinePoints, p)) outlinePoints.Add(p); break; } } } // Added to close the loop outlinePoints.Add(outlinePoints[0]); image.UnlockBits(bitmapData); return outlinePoints.ToArray(); } public static bool ContainsPoint(IEnumerable<Point> points, Point value) { foreach (Point p in points) { if (p == value) return true; } return false; } And when I turn the points into a path: GraphicsPath outlinePath = new GraphicsPath(); outlinePath.AddLines(_outlinePoints); Here's an example showing what I want. The red outline should be an array of points which can be made into a GraphicsPath in order to perform hit detection, draw an outline pen, and fill it with a brush.

• hadoop install cluster

  Is it possible to run hadoop on multi-node and these nodes install hadoop on different paths? I noticed the tutorial, such as Michael Noll's, http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-multi-node-cluster/, asks hadoop to be installed on different nodes with the same installation path. I tried to run hadoop on multi-node. Each node installed hadoop on different path. But not success. I noticed that the hadoop assume installation paths are the same in default.

I noticed the tutorial, such as Michael Noll's, http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-multi-node-cluster/, asks hadoop to be installed on different nodes with the same installation path. I tried to run hadoop on multi-node. Each node installed hadoop on different path. But not success. I noticed that the hadoop assume installation paths are the same in default. The problem is when I execute start-dfs.sh it tries to start hadoop deamons on the salve nodes from the same path as on master. "Whereas the installation path is different. Were the relevant files modified to reflect the installed locations on each node"? Which file I should modify to reflect the installed locations on each node?
