• Explain difference in SQLIO numbers for RAID 0 versus RAID 5 over 6 disks

  - by markn

  When using the SQLIO benchmark tool on a 4-core Dell server with 6 15k 450GB (fast) drives, RAID 0, we found the max throughput was 2MB per second. But when configured as RAID 5, we get 30 MB per second. It seems that the RAID controller, Dell Perc 5i integrated controller, is maxing out the throughput per disk. With RAID 5, I expect to get a bump due to stripping, but not a 15x difference. Like good programmers, we suspect the hardware , but we could be missing something. This is predominately write traffic.

• EXC_BAD_INSTRUCTION (SIGILL) at random during use of app. Bug in AppKit?

  - by Ger Teunis

  I'm currently testing a new version of an app of mine on OSX 10.5 An user reported some weird crashes during use of the application, sadly not reproducible by me. At first sight it seems to happen randomly, once he had the crash while opening an NSOpenPanel and once during focusing an NSTextField and once during NSView switch in a parent view. If you have any idea which area I should look at it would be greatly appreciated! I'm completely lost here. App is compiled in XCode 3.2.1 with SDK 10.5 and targetted at 10.5 He send me these crashes: Crash 1 Process: NZBVortex [43622] Path: /Users/cero/Downloads/NZBVortex.app/Contents/MacOS/NZBVortex Identifier: com.NZBVortex.NZBVortex Version: 0.5.5 (0.5.5) Code Type: X86-64 (Native) Parent Process: launchd [97] Interval Since Last Report: 1951 sec Crashes Since Last Report: 1 Per-App Interval Since Last Report: 1858 sec Per-App Crashes Since Last Report: 1 Date/Time: 2010-03-23 23:43:49.671 +0100 OS Version: Mac OS X 10.5.8 (9L31a) Report Version: 6 Anonymous UUID: 98AB0386-590B-4E0D-B7AC-3F7AA4E7238E Exception Type: EXC_BAD_INSTRUCTION (SIGILL) Exception Codes: 0x0000000000000001, 0x0000000000000000 Crashed Thread: 0 Application Specific Information: objc[43622]: alt handlers in objc runtime are buggy! - Hide quoted text - Thread 0 Crashed: 0 libobjc.A.dylib 0x00007fff82baef6e _objc_fatal + 238 1 libobjc.A.dylib 0x00007fff82bb2ea4 objc_addExceptionHandler + 302 2 com.apple.CoreFoundation 0x00007fff842b1090 _CFDoExceptionOperation + 528 3 com.apple.AppKit 0x00007fff81f75e26 _NSAppKitLock + 81 4 com.apple.AppKit 0x00007fff81f80f8f -[NSView nextKeyView] + 56 5 com.apple.AppKit 0x00007fff81f81018 -[NSView _primitiveSetNextKeyView:] + 72 6 com.apple.AppKit 0x00007fff820732b1 -[NSView _recursiveSetDefaultKeyViewLoop] + 242 7 com.apple.AppKit 0x00007fff82073300 -[NSView _recursiveSetDefaultKeyViewLoop] + 321 8 com.apple.AppKit 0x00007fff82073300 -[NSView _recursiveSetDefaultKeyViewLoop] + 321 9 com.apple.AppKit 0x00007fff82073300 -[NSView _recursiveSetDefaultKeyViewLoop] + 321 10 com.apple.AppKit 0x00007fff82073300 -[NSView _recursiveSetDefaultKeyViewLoop] + 321 11 com.apple.AppKit 0x00007fff82072fc3 -[NSView _setDefaultKeyViewLoop] + 279 12 com.apple.AppKit 0x00007fff82072e70 -[NSWindow recalculateKeyViewLoop] + 36 13 com.apple.AppKit 0x00007fff821dd149 -[NSSavePanel(NSSavePanelRuntime) _loadPreviousModeAndLayout] + 39 14 com.apple.AppKit 0x00007fff821dcf9e -[NSSavePanel(NSSavePanelRuntime) runModalForDirectory:file:types:] + 71 15 com.NZBVortex.NZBVortex 0x000000010000b7ee -[MainWindowViewController openNZBFileButtonClick:] + 62 16 com.apple.AppKit 0x00007fff821c96bf -[NSToolbarButton sendAction:to:] + 77 17 com.apple.AppKit 0x00007fff821c8bb7 -[NSToolbarItemViewer mouseDown:] + 5362 18 com.apple.AppKit 0x00007fff82082783 -[NSWindow sendEvent:] + 5068 19 com.apple.AppKit 0x00007fff8204fd46 -[NSApplication sendEvent:] + 5089 20 com.apple.AppKit 0x00007fff81faa562 -[NSApplication run] + 497 21 com.apple.AppKit 0x00007fff81f772f0 NSApplicationMain + 373 22 com.NZBVortex.NZBVortex 0x0000000100012a69 main + 9 23 com.NZBVortex.NZBVortex 0x0000000100001a84 start + 52 Crash 2 Process: NZBVortex [43600] Path: /Users/cero/Downloads/NZBVortex.app/Contents/MacOS/NZBVortex Identifier: com.NZBVortex.NZBVortex Version: 0.5.5 (0.5.5) Code Type: X86-64 (Native) Parent Process: launchd [97] Interval Since Last Report: 727 sec Crashes Since Last Report: 1 Per-App Interval Since Last Report: 616 sec Per-App Crashes Since Last Report: 1 Date/Time: 2010-03-23 23:11:20.000 +0100 OS Version: Mac OS X 10.5.8 (9L31a) Report Version: 6 Anonymous UUID: 98AB0386-590B-4E0D-B7AC-3F7AA4E7238E Exception Type: EXC_BAD_INSTRUCTION (SIGILL) Exception Codes: 0x0000000000000001, 0x0000000000000000 Crashed Thread: 0 Application Specific Information: objc[43600]: alt handlers in objc runtime are buggy!

• Decoding a GIF question

  - by teehoo

  For a personal project I'm creating a static gif decoder. Everything works well so far, except I'm having trouble understanding one concept from the specification: This block is REQUIRED for an image. Exactly one Image Descriptor must be present per image in the Data Stream. An unlimited number of images may be present per Data Stream. (Spec) Unlimited images per data stream? There can be more than 1? I'm assuming they don't mean an animated GIF because in the same specification they state, that they don't recommend gif's be used for animation. I've read a lot of other sites documenting the gif format and they all state something similar. Heres another link: There might be an unlimited number of images present in a GIF. Any ideas?

• How do I regenerate statistics in Openx?

  - by Martin Bauer

  ue to faulty hardware, statistics generated over a 2 week period were significantly higher than normal (10000 times higher than normal). After moving the application to a new server, the problem rectified itself. The issue I have is that there are 2 weeks of stats that are clearly wrong. I have checked the raw impressions table for the affected fortnight and it seems to be correct (ie. stats per banner per day match the average for the previous month). Looking at the intermediate & summary impressions tables, the values are inflated. I understand from the openx forum (http://forum.openx.org/index.php?s=7796fd9dae40e020a010773746f3ada9&showtopic=503424297) it's possible to regenerate stats from the raw data but it will only regenerate stats per hour, meaning regenerating stats for 2 weeks would be very time consuming. Is there another, more efficient way to regenerate the stats from the raw data for the affected fortnight?

• Work Experience - Internship Years

  - by James Jones

  I interned at my current place of employment for 2.5 years while I was an undergrad. During that time, I worked 40 hours per week during the summer and averaged 20 hours per week during the school year. I have since been hired full-time and I have been with the company a little over 3 years now. How many years of work experience do I have? Background info: There is a significant income disparity between someone with 1 year of experience vs 3 years (as per salary.com). I have job responsibilities equivalent to that of someone who has been at my company for about 5 years. I am trying to determine what I should expect in terms of income, raises, etc.

• When should I open and close a website's cached WCF proxy?

  - by Brandon Linton

  I've browsed around the other articles on StackOverflow that relate to caching WCF proxies for reuse, and I've read this article explaining why I should explicitly open the proxy before calling anything on it. I'm still a little hazy on the best implementation details. My question is: when should I open and close proxies for service calls on a website, and what should their lifetime be (per call, per request, or per web app)? We aren't planning on leveraging cached security contexts at the moment (but it's not unforeseeable). Thanks!

• Java - JPA - When we need more than one EntityManager?

  - by Yatendra Goel

  I am learning JPA and have one question: In which situations we need more than one EntityManager in our application? The two situations that I am aware of are as follows: When our application is a multi-threaded application and more than one thread needs JPA transaction because EntityManager is not thread-safe and we need one EntityManager per thread. When any of the thread needs multiple concurrent transactions, we need more than one EntityManager in that thread because there is one-to-one relationship between EntityManager and EntityTransaction. Q1. Are there any other situations when we need more than one EntityManager? ================================================================================= Q2. Upto my understanding, there should be only one EntityManagerFactory per Persitence Unit. Am I correct? If not, then what are those situations when we need multiple EntityManagerFactory per Persistence Unit?

• SQL to retrieve the latest records, grouping by unique foreign keys

  - by jbox

  I'm creating query to retrieve the latest posts in a forum using a SQL DB. I've got a table called "Post". Each post has a foreign key relation to a "Thread" and a "User" as well as a creation date. The trick is I don't want to show two posts by the same user or two posts in the same thread. Is it possible to create a query that contains all this logic? # Grab the last 10 posts. SELECT id, user_id, thread_id FROM posts ORDER BY created_at DESC LIMIT 10; # Grab the last 10 posts, max one post per user SELECT id, user_id, thread_id FROM post GROUP BY user_id ORDER BY date DESC LIMIT 10; # Grab the last 10 posts, max one post per user, max one post per thread???

• Low noise sites to keep track of news related to computers & programming?

  - by Sridhar Ratnakumar

  I am aware of sites like Slashdot and Ars Technica. Unfortunately they publish way too many articles per day. Ars Technical: 100 posts per week Slashdot: 179 posts per week And I prefer not to waste my attention over reading about 180 posts (even if I were to skim) every week. Is there a site that provides only important news - excluding not-so-important news items like top 6 iPad apps that someone is dying to try out (but haven't done yet; still thinks their readers/advertisers care about it)?

• Node.js vs PHP processing speed

  - by Cody Craven

  I've been looking into node.js recently and wanted to see a true comparison of processing speed for PHP vs Node.js. In most of the comparisons I had seen, Node trounced Apache/PHP set ups handily. However all of the tests were small 'hello worlds' that would not accurately reflect any webpage's markup. So I decided to create a basic HTML page with 10,000 hello world paragraph elements. In these tests Node with Cluster was beaten to a pulp by PHP on Nginx utilizing PHP-FPM. So I'm curious if I am misusing Node somehow or if Node is really just this bad at processing power. Note that my results were equivalent outputting "Hello world\n" with text/plain as the HTML, but I only included the HTML as it's closer to the use case I was investigating. My testing box: Core i7-2600 Intel CPU (has 8 threads with 4 cores) 8GB DDR3 RAM Fedora 16 64bit Node.js v0.6.13 Nginx v1.0.13 PHP v5.3.10 (with PHP-FPM) My test scripts: Node.js script var cluster = require('cluster'); var http = require('http'); var numCPUs = require('os').cpus().length; if (cluster.isMaster) { // Fork workers. for (var i = 0; i < numCPUs; i++) { cluster.fork(); } cluster.on('death', function (worker) { console.log('worker ' + worker.pid + ' died'); }); } else { // Worker processes have an HTTP server. http.Server(function (req, res) { res.writeHead(200, {'Content-Type': 'text/html'}); res.write('<html>\n<head>\n<title>Speed test</title>\n</head>\n<body>\n'); for (var i = 0; i < 10000; i++) { res.write('<p>Hello world</p>\n'); } res.end('</body>\n</html>'); }).listen(80); } This script is adapted from Node.js' documentation at http://nodejs.org/docs/latest/api/cluster.html PHP script <?php echo "<html>\n<head>\n<title>Speed test</title>\n</head>\n<body>\n"; for ($i = 0; $i < 10000; $i++) { echo "<p>Hello world</p>\n"; } echo "</body>\n</html>"; My results Node.js $ ab -n 500 -c 20 http://speedtest.dev/ This is ApacheBench, Version 2.3 <$Revision: 655654 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking speedtest.dev (be patient) Completed 100 requests Completed 200 requests Completed 300 requests Completed 400 requests Completed 500 requests Finished 500 requests Server Software: Server Hostname: speedtest.dev Server Port: 80 Document Path: / Document Length: 190070 bytes Concurrency Level: 20 Time taken for tests: 14.603 seconds Complete requests: 500 Failed requests: 0 Write errors: 0 Total transferred: 95066500 bytes HTML transferred: 95035000 bytes Requests per second: 34.24 [#/sec] (mean) Time per request: 584.123 [ms] (mean) Time per request: 29.206 [ms] (mean, across all concurrent requests) Transfer rate: 6357.45 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.2 0 2 Processing: 94 547 405.4 424 2516 Waiting: 0 331 399.3 216 2284 Total: 95 547 405.4 424 2516 Percentage of the requests served within a certain time (ms) 50% 424 66% 607 75% 733 80% 813 90% 1084 95% 1325 98% 1843 99% 2062 100% 2516 (longest request) PHP/Nginx $ ab -n 500 -c 20 http://speedtest.dev/test.php This is ApacheBench, Version 2.3 <$Revision: 655654 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking speedtest.dev (be patient) Completed 100 requests Completed 200 requests Completed 300 requests Completed 400 requests Completed 500 requests Finished 500 requests Server Software: nginx/1.0.13 Server Hostname: speedtest.dev Server Port: 80 Document Path: /test.php Document Length: 190070 bytes Concurrency Level: 20 Time taken for tests: 0.130 seconds Complete requests: 500 Failed requests: 0 Write errors: 0 Total transferred: 95109000 bytes HTML transferred: 95035000 bytes Requests per second: 3849.11 [#/sec] (mean) Time per request: 5.196 [ms] (mean) Time per request: 0.260 [ms] (mean, across all concurrent requests) Transfer rate: 715010.65 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.2 0 1 Processing: 3 5 0.7 5 7 Waiting: 1 4 0.7 4 7 Total: 3 5 0.7 5 7 Percentage of the requests served within a certain time (ms) 50% 5 66% 5 75% 5 80% 6 90% 6 95% 6 98% 6 99% 6 100% 7 (longest request) Additional details Again what I'm looking for is to find out if I'm doing something wrong with Node.js or if it is really just that slow compared to PHP on Nginx with FPM. I certainly think Node has a real niche that it could fit well, however with these test results (which I really hope I made a mistake with - as I like the idea of Node) lead me to believe that it is a horrible choice for even a modest processing load when compared to PHP (let alone JVM or various other fast solutions). As a final note, I also tried running an Apache Bench test against node with $ ab -n 20 -c 20 http://speedtest.dev/ and consistently received a total test time of greater than 0.900 seconds.

• How can I hide tracing code in Visual Studio IDE C# ?

  - by Mark

  As I'm starting to put more tracing in my code, i'm realizing it adds a lot of clutter. I know Visual Studio allows you to hide and reveal code, however, i'd like to be able group code into "tracing" code and then hide it and reveal at will as i'm reading the code. I suppose it could do this either per file or per class or per function. Is there any way to do this? What do you guys do? Adding some clarification The hide current feature kind of allows you to do this except that when the code is hidden, you can't tell if its tracing or not. You also can't say "hide all tracing code" and "reveal all tracing code" which is useful when reading a function depending on what you are trying to do.

• Efficiently storing a list of prime numbers

  - by eSKay

  This article says: Every prime number can be expressed as 30k±1, 30k±7, 30k±11, or 30k±13 for some k. That means we can use eight bits per thirty numbers to store all the primes; a million primes can be compressed to 33,334 bytes "That means we can use eight bits per thirty numbers to store all the primes" This "eight bits per thirty numbers" would be for k, correct? But each k value will not necessarily take-up just one bit. Shouldn't it be eight k values instead? "a million primes can be compressed to 33,334 bytes" I am not sure how this is true. We need to indicate two things: VALUE of k (can be arbitrarily large) STATE from one of the eight states (-13,-11,-7,-1,1,7,11,13) I am not following how 33,334 bytes was arrived at, but I can say one thing: as the prime numbers become larger and larger in value, we will need more space to store the value of k. How, then can we fix it at 33,334 bytes?

• NHibernate transaction management in ASP.NET MVC - how should it be done?

  - by adrin

  I am writing a simple ASP.NET MVC using session per request and transaction per request patterns (custom HttpModule). It seems to work properly, but.. the performance is terrible (a simple page loads ~7 seconds). For every http request, graphical resources incuding (all images on the site) a transaction is created and that seems to delay the loading times (without the transactions loading times per one image are ~1-10 ms with transactions they are over 1 second). What is the proper way to manage transactions in ASP.NET MVC + NH stack? When i've put all transactions into my repository methods, for some obscure reasons I got 'implicit transactions' warning in NHProf (the SQL statements were executed outside transaction, even that in code session.Save()/Update()/etc methods were invoked within transaction 'using' scope and before transaction.Commit() call) BTW are implicit transactions really bad?

  I can use the following to group results, but it only returns one result per group. @results = Model.search params[:search_query], :group_by => 'created_at', :group_function => :day, :page => params[:page], :per_page => 50 So, if I display the results by day, I only get one result per day. <% @results.each_with_groupby do |result, group| %> <div class="group"><%= group %></div> <ul class="result"> <li><%= result.name %></li> </ul> <% end %> Do I have to parse the @results array and group them by date manually or am I missing something? Here is the line from the sphinx docs: http://sphinxsearch.com/docs/current.html#clustering "The final search result set then contains one best match per group."

• How can I make Excel's MIN function ignore zeroes in a set?

  - by mfg

  In Excel, I have the following formula =(MIN(H69,H52,H35,H18)*(1/H18))*10 that is supposed to return the MIN of a range, and divide it by the current cell (*(1/H18) ), then multiply by 10. I am having difficulty with adding a type of NULLIF statement. I want to be able to have (the possibility for) blank rows, and have the MIN function ignore zero/blank fields while selecting the next lowest value (all are between 1.0-0.1). Is there a modifier i can apply to the MIN function to make it not compare zeroes in the MIN set? Is there a better funtion than MIN to use? This is to prevent the following situation: users will need to eliminate fields that are zeros from the form, theres 2 formula edits per entry, averaging 4 entries per use, so 8 possible errors per form use...

• UIButton to be resized

  - by Sathiya

  I am using a UIButton in my application. This button title is displayed dynamically as per the user choice. Now i have to resize the button width as per the title content. I am calculating the string length and assigning it to button's width. the button is resized as per title but the problem is as follows, 1. If at first the title with large content is shown and after that if a title with a small content is shown means the button is overwritten it doesn't remove the previously constructed value. 2. it looks as if one button is overlapped on the another.

  - by malaki1974

  The code below works great except the email has all the text on one line like this: Height: 60 | Diagonal: 123 | Width: 107 | Total SF: 13.92 | Cost Per SF: 450 | Total Cost: $6,264.00 I would like to break after each so it looks like this: Height: 60 Diagonal: 123 Width: 107 Total SF: 13.92 Cost Per SF: 450 Total Cost: $6,264.00 I tried \n \r \n\r etc but none of them work. Any ideas? <a class="emailText" href="mailto:?subject=Screen Dimensions" onclick="this.href='mailto:?subject=Screen Dimensions&body='+'Height: '+document.forms.myform.high.value+' | '+'Diagonal: '+document.forms.myform.diagonal.value+' | '+'Width: '+document.forms.myform.wide.value+' | '+'Total SF: '+document.forms.myform.sf.value+' | '+'Cost Per SF: '+document.forms.myform.csf.value+' | '+'Total Cost: '+document.forms.myform.tc.value">Email</a>

• How many records can i store in a Sql server table before it's getting ugly?

  - by Michel

  Hi, i've been asked to do some performance tests for a new system. It is only just running with a few client, but as they expect to grow, these are the numbers i work with for my test: 200 clients, 4 years of data, and the data changes per.... 5 minutes. So for every 5 minutes for every client there is 1 record. That means 365*24*12 = 105.000 records per client per year, that means 80 milion records for my test. It has one FK to another table, one PK (uniqueidentifier) and one index on the clientID. Is this something SqlServer laughs about because it isn't scaring him, is this getting too much for one quad core 8 GB machine, is this on the edge, or..... Has anybody had any experience with these kind of numbers?

• How to put 1000 lightweight server applications in the cloud

  - by Dan Bird

  The company I work for sells a commercial desktop/server app that runs on any non dedicated Windows PC or server and uses Tomcat for all interactions with the application. Customers are asking that we host their instance of the application so they don't have to run it locally on their own servers. The app is lightweight and an average server, in theory, could handle 25-50 instances before users would notice a slowdown. However only 1 instance can run per Windows instance (because the application writes to a common registry branch) so we'd need something like VMWare to create 25-50 Windows instances. We know we eventually need to reprogram to make it truly cloud-worthy but what would you recommend for a server farm or whatever for this? We don't have the setup to purchase our own servers so we must use a 3rd party. We have budgeted $500 - $1000 per year per customer for this service. Thanks in advance for your suggestions, experiences and guidance.

• who wrote 250k tests for webkit?

  - by amwinter

  assuming a yield of 3 per hour, that's 83000 hours. 8 hours a day makes 10,500 days, divide by thirty to get 342 mythical man months. I call them mythical because writing 125 tests per person per week is unreal. can any wise soul out there on SO shed some light on what sort of mythical men write unreal quantities of tests for large software projects? thank you. update chrisw thinks there are only 20k tests (check out his explanation below). PS I'd really like to hear from folks who have worked on projects with large test bases

• Normalise this Table?

  - by Abs

  Hello all, I am creating a social bookmarking app. I am having a re-thought of the DB design in the middle of development. Should I normalise the bookmarks table and remove the tag columns that I have into a separate table. I have 10 tags per bookmark and therefore 10 columns per record (per bookmark). It seems to me that breaking the table into two would just mean I would have to do a join but the way I currently have it, its a straight select - but the table doesn't feel right...? Thanks all

• Preventing dictionary attacks on a web application

  - by Kevin Pang

  What's the best way to prevent a dictionary attack? I've thought up several implementations but they all seem to have some flaw in them: Lock out a user after X failed login attempts. Problem: easy to turn into a denial of service attack, locking out many users in a short amount of time. Incrementally increase response time per failed login attempt on a username. Problem: dictionary attacks might use the same password but different usernames. Incrementally increase response time per failed login attempt from an IP address. Problem: easy to get around by spoofing IP address. Incrementally increase response time per failed login attempt within a session. Problem: easy to get around by creating a dictionary attack that fires up a new session on each attempt.

• How do you calculate the storage size of a SimpleDB domain?

  - by C. Dragon 76

  The official documentation states: Raw byte size (GB) of all item IDs + 45 bytes per item + Raw byte size (GB) of all attribute names + 45 bytes per attribute name + Raw byte size (GB) of all attribute-value pairs + 45 bytes per attribute-value pair What is the raw size of an attribute-value pair? Is it precisely the size of the value? (I would expect so, but then why is it worded "attribute-value pair"?) Or is it the size of the attribute name plus the size of the attribute value? (In that case, there would be motivation to give your attributes really short names.) For example, what is the size of the tiny domain below? +---------------------------------------------------------+ | Item Name/ID | "Price" attribute | "Calories" attribute | |--------------+-------------------+----------------------| | "apple" | "0000.43" | "0046" | | "orange" | "0000.70" | "0053" | +---------------------------------------------------------+

• Wicket and a rich ajax website: easiest way to do it?

  - by Sherkaner

  I want to use Wicket to build an application, but I have some designers that would like to write/maintain the javascript, and they basically expect 1 JS-segment per page, and a global JS-file. I think the most natural way to add javascript in wicket is to add it per component (not per page), which would create problems for those designers (fractioned javascript, and having to write it in java-files). Is there a better way to solve this? (of course, I expect things to work after a partial refresh.) And a second (related) thing they'd like (and I'd like actually) is the possibility to request information in JSON-format through a static link , is this possible in Wicket?
