• Visual Studio 2005 and SQL Express 2008

  Hi all, We are having some issues applying the patch for VS 2005 standard: http://www.microsoft.com/downloads/details.aspx?FamilyID=e1109aef-1aa2-408d-aa0f-9df094f993bf&displaylang=en This works fine in profesional edition, but not a machine running standard. We have checked it has all the pre-resequites but no luck at all. The error is saying the patch cannot be applied because another patch is missing, but again, we have checked and checked and checked. Now, the KB article: http://support.microsoft.com/kb/954961 Says Pro and Team editions, no mention of Standard. Judging by how simple it has been to apply this patch to VS 05 pro, and this KB article, we are starting to come to the conlcusion that it is the version. Anyone had this issue? Try as we might we cant find any work around

• Many Associations Leading to Slow Query

  - by Joey Cadle

  I currently have a database that has a lot of many to many associations. I have services which have many variations which have many staff who can perform the variation who then have details on themselves like name, role, etc... At 10 services with 3 variations each and up to 4 out of 20 staff attached to each service even doing something as getting all variations and the staff associated with them takes 4s. Is there a way I can reduce these queries that take a while to process? I've cut down the queries by doing eager loading in my DBM to reduce the problems that arise from 1+N issues, but still 4s is a long query for just a testing stage. Is there a structure out there that would help make such nested many to many associations much quicker to select? Maybe combining everything past the service level into a single table with a 'TYPE' column ?? I'm just not knowledgable enough to know the solution that turns this 4s query into a 300MS query... Any suggestions would be helpful.

• HELP! How can I display one style in Safari and a different style in Chrome?

  - by aWarner

  My client is starting to get antsy....so any help would be greatly appreciated. I am having issues with my secondary page header images shifting. It is displaying correctly in Firefox, I haven't been able to check in IE yet w/out access to a PC. It was displaying correctly in Chrome, but shifting in Safari. I added the "webkit hack" to write a specific css style for Safari, but once I did that....it started shifting in Chrome. What can I do to fix this issue?? http://airwavetelecom.net/beta/?page_id=2

• Inserting asyncronously into Oracle, any benefits?

  - by Karl Trumstedt

  I am using ODP.NET for loading data into Oracle. I am bulking inserts into groups of a 1000 rows each call. Is there any performance benefits in calling my load method asynchronously? So say I want to insert 10000 rows, instead of making 10 calls synchronously I make 10 calls asynchronously. My database is using ASSM right now but otherwise plenty of freelists are used of course. The database server has several cores as well. My initial tests seem to point to a performance increase, but maybe there is something I cannot see? Potential deadlock or contention issues? Of course, there is added complexity in handling transactions and such doing my load this way.

• Does the box API require case-sensitive booleans?

  - by Nick Chadwick

  I'm having some issues with the box.com developer API, and it seems that this is due to the API requiring lower-case booleans in request parameters. When I make a call to say, delete a folder, the URI my framework is generating looks like this: (DELETE) https://api.box.com/2.0/folders/1234?recursive=True This doesn't work, and the API throws an error. However, if I manually set the URI to this: (DELETE) https://api.box.com/2.0/folders/1234?recursive=true Everything seems to work just fine. I'd like to confirm that this is indeed the behavior, and if it is, I'd like to request box fix their API!

• mysql ON DUPLICATE KEY UPDATE

  - by julio

  Hi-- I'm stuck on a mySQL query using ON DUPLICATE KEY UPDATE. I'm getting the error: mySQL Error: 1062 - Duplicate entry 'hr2461809-3' for key 'fname' The table looks like this: id int(10) NOT NULL default '0', picid int(10) unsigned NOT NULL default '0', fname varchar(255) NOT NULL default '', type varchar(5) NOT NULL default '.jpg', path varchar(255) NOT NULL default '', PRIMARY KEY (id), UNIQUE KEY fname (fname), KEY picid (propid) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; And the query that's breaking is this: INSERT INTO images SET picid=732, fname='hr2461809-3', path='pictures/' ON DUPLICATE KEY UPDATE picid=732, fname='hr2461809-3', path='pictures/' I'm using a very similar query elsewhere in the app with no issues. I'm not sure why this one breaks. I expected that when the UNIQUE KEY on fname gets violated, that it would simply update the row where the violation occurred? Thanks for any help

• Why There is a difference between assembly languages like Windows, Linux ?

  - by mcaaltuntas

  I am relatively new to all this low level stuff,assembly language.. and want to learn more detail. Why there is a difference between Linux, Windows Assembly languages? As I understand when I compile a C code Operating system does not really produce pure machine or assembly code, it produces OS dependent binary code.But why ? For example when I use a x86 system, CPU only understands x86 ASM am I right?.So Why we dont write pure x86 assembly code and why there are different assembly variations based on Operating system? If we would write pure ASM or OS produce pure ASM there wouldn't be binary compatilibty issues between Operating systems or Not ? I am really wondering all reasons behind them. Any detailed answer, article, book would be great. Thanks.

• Floating point Endianness?

  - by cake

  Hi I'm writing a client and a server for a realtime offshore simulator, and, as I have to send a lot of data through a socket, I'm using binary data to maximize the ammount of data I can send. I already know about integers endianness, and how to use htonl and ntohl to circumvent endianness issues, but my application, as almost all simulation software, deals with a lot of floats. My question is: Is there some issue of endianness whean dealing with binary formats of floating point numbers? I know that all the machines where my code will run use IEEE implementation of floating points, but is there some endianness issue when dealing with floats? Since I only have access to machines with the same endian, I cannot test this by myself. So, I'll be glad if someone can help me with this. Thanks in advance.

• On iPhone, how do I check once per day to see if i should phone-home?

  - by Jann

  I want to check a file on the server only once each day (NSURL). And, no matter if I fetch the file or not, I do not run the function (to check for the file) again that day. This would SEEM easy... but I forsee issues. Say I had created a directory under the mainBundle: "/Library/runOnceEachDay/". Perhaps I could write to /Library/runOnceEachDay/20100601 knowing that file would only exist if I already ran the function. If it does not exist, run the function and after the function is successful write a zero length file with the date as the filename. Then check before running that function for "mainBundle/Library/runOnceEachDay/YYYYMMDD" whereas YYYYMMDD is today's date. If that file exists, do not run. I could run a housecleaning routine to clean that directory once/week or something. Any better ideas? Thanks!

• Are SqlCipher open cursors a security concern?

  - by user1178479

  I'm using SqlCipher with content providers. Right now, when I want to lock the app I just clear out the cached password. However, the app can continue to work with any open cursors. This means that re-opening the app grants access to the sensitive data. I fix this issue on the surface by redirecting to a login screen if the app doesn't have passwords. However, I'm concerned if there are any security issues with these open cursors or if I should just continue to block UI access and not worry? SqlCipher's docs say that it reads/writes encrypted pages on the fly, as opposed to decrypting the entire DB, this makes me think that open cursors are still secure. The main concern here is that someone loses their phone and then a knowledgeable individual can use these open cursors to extract sensitive data.

• pitfalls with mixing storage engines in mysql with django?

  - by Dave Orr

  I'm running a django system over mysql in amazon's cloud, and the database default is innodb. But now I want to put a fulltext index on a couple of tables for searching, which evidently requires myisam. The obvious solution is to just tell mysql to ALTER TABLE to myisam, but are there going to be any issues with that? One that comes to mind is that I'll have to remember to do that any time I build a new version of the database, which should theoretically be rare, but there doesn't seem to be a way to tell django to please set the storage engine at the table level. I guess I could write a migration (we use south). Any other things I might be missing? What could possibly go wrong?

• Best and safest Java Profiler for production use?

  - by Pete

  I'm looking for a Java Profiler for use in a very high demand production environment, either commercial or free, that meets all of the following requirements: Lightweight integration with code (no recompile with special options, no code hooks, etc). Dropping some profiler specific .jars alongside the application code is ok. Should be able to connect/disconnect to the JVM without restarting the application. When profiling is not active, no impact to performance When profiling is active, negligible impact to performance. Very slight degradation is acceptable. Must do all the 'expected' stuff a profiler does - time spent in each method to find hotspots, object allocation/memory profiling, etc. Essentially I need something that can sit dormant in production when everything is fine without anyone knowing or caring that it is there, but then be able to connect to it hassle (and performance degradation) free to pinpoint the hard to find problems like hotspots and synchronization issues.

• How do I bind a key to "the function represented by the following key sequence"?

  - by katrielalex

  I'm just starting to learn emacs (woohoo!) and I've been mucking around in my .emacs quite happily. Unfortunately, I don't know Lisp yet, so I'm having issues with the basics. I've already remapped a few keys until I fix my muscle memory: (global-set-key (kbd "<f9>") 'recompile) That's fine. But how can I tell a key to 'simulate pressing several keys'? For instance, I don't know, make <f1> do the same as C-u 2 C-x } (widen buffer by two chars). One way is to look up that C-x } calls shrink-window-horizontally, and do some sort of lambda thing. This is of course the neat and elegant way (how do you do this?). But surely there's a way to define <f1> to send the keystrokes C-u 2 C-x }?

• WCF interoperability with WSDL proxy and performance consideration advise.

  - by user194917

  I'm essentially writing a broker service. The requirement is that I write an API that acts as an intermediary broker between our in-house developed services and a 3rd party provided API. The intention being that my API abstract the actual communication with the 3rd party API from our internal systems. The architect on the project chose WCF as the communication framework. The problem is that 70 percent of our subscriber applications are written in .Net 2 and as such have no access to the class libraries required to implement a WCF proxy. The end result being that our proxy classes are loosely based on the code auto generated by the WSDL tool as opposed to the SvcUtil tool. My question is, although I have no issues implementing the required proxy classes using basicHttp as the actual binding and using the WSDL tool, are there any special considerations that I need to take into account in this scenario? I.E proxy optimizations and the like. Thanks in advance.

• Template approach for a PHP application

  - by Industrial

  Hi everyone, We're in the middle of making a new e-commerce related PHP application and we have come to the point where we have started to think about how we should solve templating for our customers needs. What we would like to do is offer our customers the possibility of uploading/modifying templates to suit their company:s profile. The initial thought is that we shall not reinvent the wheel, so instead letting our customers upload their templates with FTP, so there will be basic HTML skills required. For those customers that want to modify/customize template and doesnt have the knowledge, we offer that service as well. I know that there's a number of issues to solve before this could be considered safe, like preventing XSS and writing scripts that check through each uploaded file for potential security threats and so on. Of course, there are some part that probably will be to complex for the customer to modify by themselves, so maybe this approach won't apply to all<< template files in the frontend application. But besides that, what would be a good way to handle this?

• How do I prevent an https response from throwing an AuthenticationException with Fiddler running?

  - by Ichabod Clay

  Relative newbie to C# here :) I'm currently creating a web link scraper and having issues with the responses I'm getting when trying to login to the website via my program. I'm trying to use Fiddler to see if my program is sending the proper data, but my program is throwing an AuthenticationException when trying to get a response from the site with Fiddler running. The requests are being sent over HTTPS and Fiddler's certificate is the cause of the excepting being thrown. My question is, what can I implement into my program to have it disregard the certificate authentication? As far as my program goes, the requests and responses are being handled by HttpWebRequest and HttpWebResponse classes.

• Performance Impact of Generating 100's of Dynamic Methods in Ruby?

  - by viatropos

  What are the performance issues associated with generating 100's of dynamic methods in Ruby? I've been interested in using the Ruby Preferences Gem and noticed that it generates a bunch of helper methods for each preference you set. For instance: class User < ActiveRecord::Base preference :hot_salsa end ...generates something like: user.prefers_hot_salsa? # => false user.prefers_hot_salsa # => false If there are 100's of preferences like this, how does this impact the application? I assume it's not really a big deal but I'm just wondering, theoretically.

• How to separate database entries and display them as individual records using PHP?

  - by Clark

  I used to have database entries separated by ampersands (&), but this was causing certain search issues so I decided to encapsulate my entries on both sides by $ and & symbols like: $this& But I am having trouble displaying all the entries of a cell as individual records. Before I used: $unsplitItems = $row['files']; $files = explode("@", $unsplitItems); foreach ($files as $file) { if(strlen($file)) { echo "<li>$file</li>"; } } Any idea how I can split my records and display all the items in the array as individual entries?

• T-SQL Operations on a Calculated Date Field

  - by firedrawndagger

  Can I do WHERE operations on a calculated date field? I have a lookup field, which has been written badly in SQL and unfortunately I can't change it. But basically it stores dates as characters such as "July-2010" or "June-2009" (along with other non date data). I want to extract the dates first (which I did using a LIKE opertor) and then extract data based on a date range. SELECT BusinessUnit, Lookup, ReleaseDate FROM ( SELECT TOP 10 LookupColumn As Lookup, BU as BusinessUnit, CONVERT(DATETIME, REPLACE(LookupColumn,'-',' ')) as ReleaseDate FROM [dbo].[LookupTable] WHERE LookupColumn LIKE N'%-2010' ) MyTable ORDER BY ReleaseDate WHERE ReleaseDate = '2010-02-01' I'm having issues with WHERE operator. I would assume creating a subquery to encapsulate the calculated field would allow me to do operations with it such as WHERE but maybe I'm wrong. Bottom line is it possible to do operations on calculated fields?

• finding out memory allocation hotspots in java

  - by Zamir

  Our GC is working hard and we have some pauses that we want to decrease. We have some memory allocation issues that we want to solve before or while we are tweaking with the actual JVM GC args. I would like to know which objects are making the GC sweat: is there a way to know which objects are evacuated every time the GC is working? is there a way to know which objects are moved between areas every time the GC is working? Is there a way to know which objects are in Eden area? I am working extensively with Jprofiler and Memory Analyzer. I would like to get this information on a running application in my staging environment.

• NoSQL for concurrent reads/writes

  - by Mickael Marrache

  After getting some performance issues for an application using a MySQL database, I'm thinking of using NoSQL solutions. My architecture is as follows: One application receives messages from the network at a high throughput (i.e. 50000 messages/sec). Each message is stored in the DB, so it's important for the write rate to be as fast as the arrival rate. Then, I also have some PHP pages that accesses the DB to get the data stored by the other application. It's important for me that the retrieved data is as relevant as possible (i.e. not old data, let's say not more than 5 seconds old). Also, the data is not critical, so I don't need any security mechanism to avoid losing the data. I see there are a lot of NoSQL solutions, but I don't know if they are all relevant. Could you please provide me some directions. Thanks
