• Need help tuning Mysql and linux server

  - by Newtonx

  We have multi-user application (like MailChimp,Constant Contact) . Each of our customers has it's own contact's list (from 5 to 100.000 contacts). Everything is stored in one BIG database (currently 25G). Since we released our product we have the following data history. 5 years of data history : - users/customers (200+) - contacts (40 million records) - campaigns - campaign_deliveries (73.843.764 records) - campaign_queue ( 8 millions currently ) As we get more users and table records increase our system/web app is getting slower and slower . Some queries takes too long to execute . SCHEMA Table contacts --------------------+------------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +---------------------+------------------+------+-----+---------+----------------+ | contact_id | int(10) unsigned | NO | PRI | NULL | auto_increment | | client_id | int(10) unsigned | YES | | NULL | | | name | varchar(60) | YES | | NULL | | | mail | varchar(60) | YES | MUL | NULL | | | verified | int(1) | YES | | 0 | | | owner | int(10) unsigned | NO | MUL | 0 | | | date_created | date | YES | MUL | NULL | | | geolocation | varchar(100) | YES | | NULL | | | ip | varchar(20) | YES | MUL | NULL | | +---------------------+------------------+------+-----+---------+----------------+ Table campaign_deliveries +---------------+------------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +---------------+------------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | newsletter_id | int(10) unsigned | NO | MUL | 0 | | | contact_id | int(10) unsigned | NO | MUL | 0 | | | sent_date | date | YES | MUL | NULL | | | sent_time | time | YES | MUL | NULL | | | smtp_server | varchar(20) | YES | | NULL | | | owner | int(5) | YES | MUL | NULL | | | ip | varchar(20) | YES | MUL | NULL | | +---------------+------------------+------+-----+---------+----------------+ Table campaign_queue +---------------+------------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +---------------+------------------+------+-----+---------+----------------+ | queue_id | int(10) unsigned | NO | PRI | NULL | auto_increment | | newsletter_id | int(10) unsigned | NO | MUL | 0 | | | owner | int(10) unsigned | NO | MUL | 0 | | | date_to_send | date | YES | | NULL | | | contact_id | int(11) | NO | MUL | NULL | | | date_created | date | YES | | NULL | | +---------------+------------------+------+-----+---------+----------------+ Slow queries LOG -------------------------------------------- Query_time: 350 Lock_time: 1 Rows_sent: 1 Rows_examined: 971004 SELECT COUNT(*) as total FROM contacts WHERE (contacts.owner = 70 AND contacts.verified = 1); Query_time: 235 Lock_time: 1 Rows_sent: 1 Rows_examined: 4455209 SELECT COUNT(*) as total FROM contacts WHERE (contacts.owner = 2); How can we optimize it ?

• Inbound SIP calls through Cisco 881 NAT hang up after a few seconds

  - by MasterRoot24

  I've recently moved to a Cisco 881 router for my WAN link. I was previously using a Cisco Linksys WAG320N as my modem/router/WiFi AP/NAT firewall. The WAG320N is now running in bridged mode, so it's simply acting as a modem with one of it's LAN ports connected to FE4 WAN on my Cisco 881. The Cisco 881 get's a DHCP provided IP from my ISP. My LAN is part of default Vlan 1 (192.168.1.0/24). General internet connectivity is working great, I've managed to setup static NAT rules for my HTTP/HTTPS/SMTP/etc. services which are running on my LAN. I don't know whether it's worth mentioning that I've opted to use NVI NAT (ip nat enable as opposed to the traditional ip nat outside/ip nat inside) setup. My reason for this is that NVI allows NAT loopback from my LAN to the WAN IP and back in to the necessary server on the LAN. I run an Asterisk 1.8 PBX on my LAN, which connects to a SIP provider on the internet. Both inbound and outbound calls through the old setup (WAG320N providing routing/NAT) worked fine. However, since moving to the Cisco 881, inbound calls drop after around 10 seconds, whereas outbound calls work fine. The following message is logged on my Asterisk PBX: [Dec 9 15:27:45] WARNING[27734]: chan_sip.c:3641 retrans_pkt: Retransmission timeout reached on transmission [email protected] for seqno 1 (Critical Response) -- See https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions Packet timed out after 6528ms with no response [Dec 9 15:27:45] WARNING[27734]: chan_sip.c:3670 retrans_pkt: Hanging up call [email protected] - no reply to our critical packet (see https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions). (I know that this is quite a common issue - I've spend the best part of 2 days solid on this, trawling Google.) I've done as I am told and checked https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions. Referring to the section "Other SIP requests" in the page linked above, I believe that the hangup to be caused by the ACK from my SIP provider not being passed back through NAT to Asterisk on my PBX. I tried to ascertain this by dumping the packets on my WAN interface on the 881. I managed to obtain a PCAP dump of packets in/out of my WAN interface. Here's an example of an ACK being reveived by the router from my provider: 689 21.219999 193.x.x.x 188.x.x.x SIP 502 Request: ACK sip:[email protected] | However a SIP trace on the Asterisk server show's that there are no ACK's received in response to the 200 OK from my PBX: http://pastebin.com/wwHpLPPz In the past, I have been strongly advised to disable any sort of SIP ALGs on routers and/or firewalls and the many posts regarding this issue on the internet seem to support this. However, I believe on Cisco IOS, the config command to disable SIP ALG is no ip nat service sip udp port 5060 however, this doesn't appear to help the situation. To confirm that config setting is set: Router1#show running-config | include sip no ip nat service sip udp port 5060 Another interesting twist: for a short period of time, I tried another provider. Luckily, my trial account with them is still available, so I reverted my Asterisk config back to the revision before I integrated with my current provider. I then dialled in to the DDI associated with the trial trunk and the call didn't get hung up and I didn't get the error above! To me, this points at the provider, however I know, like all providers do, will say "There's no issues with our SIP proxies - it's your firewall." I'm tempted to agree with this, as this issue was not apparent with the old WAG320N router when it was doing the NAT'ing. I'm sure you'll want to see my running-config too: ! !

• how to run multiple shell scripts in parallel

  - by tom smith

  I've got a few test scripts, each of which runs a test php app. Each script runs forever. So, cat.sh, dog.sh, and foo.sh, each run a php script, and each shell script runs the php app in a loop, so it runs forever, sleeping after each run. I'm trying to figure out how to run the scripts in parallel, and at the same time, see the output of the php apps in the stdout/term window. I thought, simply doing something like foo.sh > &2 dog.sh > &2 cat.sh > &2 in a shell script would be sufficient, but it's not working. foo.sh, runs foo.php once, and it runs correctly dog.sh, runs dog.php in a never ending loop. it runs as expected cat.sh, runs cat.php in a never ending loop *** this never runs!!! it appears that the shell script never gets to run cat.sh. if i run cat.sh by itself in a separate window/term, it runs as expected... thoughts/comments

• What characteristic of networking/TCP causes linear relation between TCP activity and latency?

  - by DeLongey

  The core of this problem is that our application uses websockets for real-time interfaces. We are testing our app in a new environment but strangely we're noticing an increasing delay in TCP websocket packets associated with an increase in websocket activity. For example, if one websocket event occurs without any other activity in a 1-minute period, the response from the server is instantaneous. However, if we slowly increase client activity the latency in server response increases with a linear relationship (each packet will take more time to reach the client with more activity). For those wondering this is NOT app-related since our logs show that our server is running and responding to requests in under 100ms as desired. The delay starts once the server processes the request and creates the TCP packet and sends it to the client (and not the other way around). Architecture This new environment runs with a Virtual IP address and uses keepalived on a load balancer to balance the traffic between instances. Two boxes sit behind the balancer and all traffic runs through it. Our host provider manages the balancer and we do not have control over that part of the architecture. Theory Could this somehow be related to something buffering the packets in the new environment? Thanks for your help.

• What should I do to make sure that IIS does not recycle my application?

  - by AngryHacker

  I have a WCF service app hosted in IIS. On startup, it goes and fetches a really expensive (in terms of time and cpu) resource to use as local cache. Unfortunately, IIS seems to recycle the process on a fairly regular basis. So I am trying to change the settings on the Application Pool to make sure that IIS does not recycle the application. So far, I've change the following: Limit Interval under CPU from 5 to 0. Idle Time-out under Process Model from 20 to 0. Regular Time Interval under Recycling from 1740 to 0. Will this be enough? And I have specific questions about the items I changed: What specifically does Limit Interval setting under CPU mean? Does it mean that if a certain CPU usage is exceeded, the application pool will be recycled? What exactly does "recycled" mean? Is the application completely torn down and started up again? What is the difference between "Worker Process shutdown" and "Application Pool recycling"? The documentation for the Idle Time-out under Process Model talks about shutting down the worker process. While the docs for Regular Time Interval under Recycling talk about application pool recycling. I don't quite grok the difference between the two. I thought the w3wp.exe is the worker process which runs the application pool. Can someone explain the difference to the application between the two? The reason for having IIS7 and IIS7.5 tags is because the app will run in both and hope the answers are the same between the versions. Image for reference:

• Getting around url block for game

  - by Josh T

  So I play a game called Battlefield Play4Free (www.battlefield.play4free.com). Its essentially a giant browser plugin. The admin on my computer used to have the url battlefield.play4free.com/en/playnow.html blocked which only blocked the page that launches the game (i found a way to launch the game without going to that page and the game worked fine). Now it blocks battlefield.play4free.com which thus blocks all subpages. However, I have found that if I change it to an https and go to https://battlefield.play4free.com/en/login.html to login and then https://battlefield.play4free.com/en/playnow.html I can launch the game. However, when the game launches the borders and everything show but the window content is just a giant blockpage (the same one that shows up when I go to battlefield.play4free.com in the browser) and the blocked page is battlefield.play4free.com (main page). Is there any way I can get around this? I need a way to make the game access the server without going through the browser i.e. make the game use a proxy to get the data or somehow get past the besafe block. I was thinking perhaps you could get around it if you could get the game to make a direct request to the server and not through the url/browser, I know this works because I have a torrenting app that even tho torrent sites are blocked in the browser, the app makes a direct request and thus is not blocked. By the way, the program that blocks everything is besafe or besecure something like that. I do have access to an admin account (on the computer not the besafe program) as well as router access and pretty much anything else. Thanks so much!

• Repairing inconsistent pages in database

  - by Raj

  We have a SQL 2000 DB. The server crashed due to Raid array failure. Now when we run DBCC CHECKDB, we get an error that there are 27 consistency errors in 9 pages. When we run DBCC PAGE on these pages, we get this: Msg 8939, Level 16, State 106, Line 1 Table error: Object ID 1397580017, index ID 2, page (1:8404521). Test (m_freeCnt == freeCnt) failed. Values are 2 and 19. Msg 8939, Level 16, State 108, Line 1 Table error: Object ID 1397580017, index ID 2, page (1:8404521). Test (emptySlotCnt == 0) failed. Values are 1 and 0. Since the indicated index is non-clustered and is created by a unique constarint that includes 2 columns, we tried dropping and recreating the index. This resulted in the following error: CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID 2. Most significant primary key is '3280'. The statement has been terminated. However running Select var_id,result_on from tests group by var_id,result_on having count(*)>1 returns 0 rows. Here is what we are planning to do: Restore a pre-server crash copy of the DB and run DBCC CHECKDB If that returns clean, then restore again with no recovery Apply all subequent TLOG backups Stop production app, take a tail log backup and apply that too Drop prod DB and rename the freshly restored DB to make it prod Start prod app Could someone please punch holes in this approach? Maybe, suggest a different approach? What we need is minimum downtime. SQL 2000 DB Size 94 GB The table that has corrupt pages has 460 Million+ rows of data Thanks for the help. Raj

• supervisord launches with wrong setuid

  - by friendzis

  I am trying to test a pilot system with nginx connecting to uwsgi served application controlled by supervisord running on ubuntu-server. Application is written in python with Flask in virtualenv, although I'm not sure if that is relevant. To test the system I have created a simple hello world with flask. I want nginx and uwsgi both to run as www-data user. If I launch uwsgi "manually" from root shell I can see uwsgi processes runing as appropriate user (www-data). Although, if I let supervisor launch the application something strange happens - uwsgi processes are runing under my user (friendzis). Consequently, socket file gets created under wrong user and nginx cannot communicate with my applicaion. note: the linux server runs as Hyper-V VM, under Windows Server 2008. Relevant configuration: [uwsgi] socket = /var/www/sockets/cowsay.sock chmod-socket = 666 abstract-socket = false master = true workers = 2 uid = www-data gid = www-data chdir = /var/www/cowsay/cowsay pp = /var/www/cowsay/cowsay pyhome = /var/www/cowsay module = cowsay callable = app supervisor [program:cowsay] command = /var/www/cowsay/bin/uwsgi -s /var/www/sockets/cowsay.sock -w cowsay:app directory = /var/www/cowsay/cowsay user = www-data autostart = true autorestart = true stdout_logfile = /var/www/cowsay/log/supervisor.log redirect_stderr = true stopsignal = QUIT I'm sure I'm missing some minor detail, but I'm unable to notice it. Would appreciate any suggestions.

• Looking for software to create a personal hotspot on Mac OS X (not using the built-in ability)

  - by Fred

  I got my nifty little MacBook Air today. Since I will be going on travel I was hoping to use my iPad 3G as screen extension with Air Display. It works being in a shared WiFi network. Sadly Apple is a bit restrictive on the tethering with their mobile devices such as the iPad. Now I read iOS 4.3 will enable the iPad to use tethered networks. But the feature will not be working for iPad 3G. I assume their big partner telecom companies fear everyone will quit their internet contract with them. So I want to create a personal hotspot on my MacBook and use it on my iPad. But the iPad is not able to use this network. The network is visible but not usable. On Windows there is this connectify program which lets the PC act as wireless router. Does anybody know a similar program for Mac which would turn it into a wireless router? Or is there something I don't see with Mac OS X's builtin features?

• How to install service packs onto Thin Apps and other questions

  - by Buzlightyear

  I have a VM that I use to do all my ThinApps, Once I have done my application and its built I copy just the bin folder to a server which has a share, I then create a shortcut to the program exe on users desktops. This all seems to work ok. Firstly is this correct? If so, how then do I apply a service pack to that application after the ThinApp VM has been reverted to a base image, I have corel draw which i have a service pack for but it wont intall it as its saying it cant find the package installed on the computer. I have Thinreg batch file so have included corel into that and the program appears in the program list. I have the sandbox redirected to the server share mentioned earlier into seperate user folders when the user logs in. Obvisouly once i have done a App I revert to a previous snapshop so my thinapp vm is back to base image, so the corel install is lost. Sorry if im missing something very simple. Is its a case if you have an exe/msp you have to reinstall the whole app again and start over, Thanks for any help.

• Mystery Print Separator Page

  - by Jesse Bradlee

  Good morning! After a recent site upgrade to WebSphere 7.0 from 6.1 on an AIX server, our users reported a print separator page appearing on a certain type of report, and only on one printer. Trouble is, no one (devs, sysadmins, users) knows where it came from or where to turn it off. Based on the info, the first step was to check the app, but we don't have print separators in our code. The report they're using also lacks even an option to separate. Then I asked the WebSphere gurus but they shook their heads. Ditto the network/print server team. If anyone can identify the source of this separator, I can take that back to the relevant team and have it switched off. They look like this (some whitespace removed for brevity): *################################################## *################################################## *################################################## *************************************************** TITLE: [document name] TIME PRINTED: Fri Sep 20 08:21:45 2013 TIME QUEUED: Fri Sep 20 08:21:45 2013 PRINTED AT: hp@hp41 (generic) @ [app name] SUBMITTED BY: root DELIVER TO: =====> root <===== *************************************************** FLAG VALUES: a-0, b=0, d=a, f=, g=1, h=, i=0, j=+, l=00, p=10, t=0, v=6, w=3--, x=2, A=1, B=gn, C=!, H=, J=+, L=+, N=1, P=[printer name]:hp@hp41, X=ISO8859-1, Z=+, 0=ibm.850 *************************************************** Thank you!

• Need to find jni.h in cmake on Mac

  - by Ilan Tal

  I am trying to make VTK compile on a Mac Air machine. I am using CMake 2.8-9, using Xcode4 as the generator. If I press the Configure button with VTK_WRAP_JAVA not checked, it will go with no errors. However I definitely need to use the wrap java since my main program is in Java and I need to get to VTK which is c++. As soon as I check the wrap Java, I get Could NOT find JNI. It apparently is looking for jni.h which in Linux there is no problem finding, but in the Mac it apparently can't find it. I did a locate jni.h and got new-host-2:~ geraldkolodny$ locate jni.h /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/System/Library/Frameworks/JavaVM.framework/Versions/A/Headers/jni.h /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/System/Library/Frameworks/JavaVM.framework/Versions/A/Headers/jni.h /Library/Java/JavaVirtualMachines/jdk1.7.0_07.jdk/Contents/Home/include/jni.h I tried to manually put into JAVA_INCLUDE_PATH2 either entry 2 or 3 (without the jni.h at the end), but it still can't find jni.h. Xcode used to have a template for jni but that is now gone in the latest version. I am fresh out of ideas on how to solve this problem. I'd be grateful for any suggestions. Thanks, Ilan

• Rails 3 passenger nginx application spawner server error on Synology NAS

  - by peresleguine

  Question updated, please read UPD2. I'm trying to deploy app through passenger nginx module on DS710+ (ruby 1.9.2p0 installed). There is syntax error relative to has_and_belongs_to_many_association.rb file. Please look at the screenshot(deleted, question updated). I'm pretty sure the problem isn't in library file. App is running good via webrick. Could you please advise what to look for?

• Apache debugging: where to find error logs?

  - by AP257

  I'm new to Apache and web serving generally, so apologies if this is a very stupid question. I want to configure a new sub-domain on a working site and install a forum there. I'm using a Debian server that already has Apache, mod_wsgi and a bunch of virtual hosts successfully running on it. I first installed my forum app (Django's OSQA). Following the OSQA instructions, I then created an Apache config file that specified ServerName as the new sub-domain. I also created a .wsgi file for the app, and pointed WSGIScriptAlias at it. I then restarted Apache. However, when I go to the new sub-domain, I get a 404 error message. Two questions: Is there a step missing above? Or is simply creating a new Apache config file in sites-available enough to 'tell' Apache about a new sub-domain? If there's something else going wrong, how can I debug it? The ErrorLog and CustomLog specified in the config file are both blank. apache2.conf, which I guess is Apache-wide configuration, specifies ErrorLog /var/log/apache2/error.log, but this is yet another blank file.

• Why can't I unblock postgres with shorewall?

  - by ryeguy

  I can't seem to unblock the port needed for postgres using Shorewall. I am developing a PHP app on my windows machine here, and then I upload it on my linux box to actually use it. The linux box runs the php files as well as hosts the db server. Since I need it working from both machines, in my PHP code I am referring to the database as the full IP instead of localhost. I can easily connect to postgres from my windows machine, but ironically, my PHP app can't connect to postgres even though it's on the same box. Here's what I have in /etc/shorewall/rules: #macro/action src dest PostgreSQL/ACCEPT net $FW PostgreSQL/ACCEPT loc $FW PostgreSQL/ACCEPT loc dmz PostgreSQL/ACCEPT net dmz PostgreSQL/ACCEPT loc net PostgreSQL/ACCEPT dmz $FW PostgreSQL/ACCEPT dmz loc PostgreSQL/ACCEPT dmz net PostgreSQL/ACCEPT dmz dmz Clearly I have a ton of crap there. The first line is all I needed to make it allow a connection from my windows machine. All the lines after it are me just trying everything to get it to work. What am I missing?

• Mod_rewrite (CakePHP routing functionality) forbidden after Snow Leopard upgrade

  - by Ryan Ballantyne

  Hello ServerFault, I am using the standard Apple-provided installations of PHP 5.3 and Apache 2 to do web development on a Mac Pro that I just upgraded to Mac OS X 10.6 (Snow Leopard). The upgrade went well enough, if I ignore the fact that it destroyed my ability to get work done. ;) After the update, the CakePHP application I was developing started giving me 403 Forbidden errors when accessed. Based on the errors in the log file, I've determined that Apache is choking on the mod_rewrite rules in Cake's .htaccess file. Here's the file, in its entirety: <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^$ app/webroot/ [L] RewriteRule (.*) app/webroot/$1 [L] </IfModule> It's not that the rules themselves are wrong, but that Apache is forbidding the use of mod_rewrite altogether. All other pages on the machine work fine, and the 403 errors go away if I comment out the .htaccess file (but nothing works, of course). In my httpd.conf file, I've tried changing this: <Directory /> Options FollowSymLinks AllowOverride None Order deny,allow Deny from all </Directory> To this: <Directory /> Options FollowSymLinks AllowOverride All Order deny,allow Allow from all </Directory> ...which has no effect. I don't know much about Apache configuration files, and I'm quite stuck on this. In fact, I know little enough that I'm not sure which information about my setup is needed to enable people to provide useful answers. I'm just using the vanilla OS X setup, nothing fancy. Googling has yielded no fruits for me this time, so I'm turning to you. Any ideas?

• IIS High use & Server Performance issues

  - by HaydnWVN

  Have an SBS2011 running Exchange, a database app and a few other things serving 5 users (3 low use, 1 high). The server was never specced for the database app so it isn't as powerful as I'd like... Only 12GB RAM. We have increasingly found performance problems with this server, last week it was so bad I couldn't even connect remotely. To free up some available RAM I have (over the past month or so): Restricted the Exchange Message Store to 1GB with (so far) no ill effects. Restricted SQL Databases (including SBSMonitoring and Sharepoint/##SSEE (Which isn't used)). Now I am finding that IIS Worker threads are using up the available memory and I have (so far) been unable to track down much useful information about restricting them. This server is not 'serving' anything web-based apart from OWA that I am finding people using because Outlook is so slow (again related to the Servers performance). I am aware that Exchange on SBS2011 is designed to use up available resources (and concede when other applications request). But it is not doing so (or anywhere near fast enough) for our needs. Opening the database application (using Postgres) takes 5+ minutes from client machines and regularly times out or crashes due to this. After a reboot (before SQL/Exchange/IIS databases are very large/totally cached) we get the performace we need and expect. Previously a reboot once a month was enough... Then once a week... Now they have taken to rebooting it almost daily!

• Will Parallel-port dongle work on USB-to-Parallel Adapter?

  - by Gary M. Mugford

  We have a niche program running on a Win2K laptop that uses a security dongle connected to a parallel port for authentication. The laptop is getting creaky and I spent a frustrating night last night shopping various websites for a new laptop that had a parallel port. Seems I'm about three years late [G]. The question I have, is, if I buy a new(ish) laptop and use a USB-to-Parallel Port adapter, will the security dongle work? I know I'm not being specific about the app, but it's one most people wouldn't have heard of anyways. I've been guessing the answer to my question is no, since the app won't know to send a request out to the non-existent port. But, if the process actually is that the dongle sends a message INTO the computer every now and then, then it might work. And, I'm not sure whether the dongle is only needed at program startup time or randomly. The dongle is a 'permanent' addition to the old laptop. This is all about the money. We can have a newly-updated version of the program (which won't add any features we need) for the princely sum of $2700. Or we can spend $500 on a refurbed laptop still running WinXP, add a 30 buck adapter and keep the same solid, stolid performance we've come to appreciate. But it all comes down to the dongle behaviour. Oh, and a dock won't work. The whole laptop issue is about moving about the various nooks and crannies of the building with laptop in hand. Thanks for any suggestions/guidance. GM

• How do I prove or disprove "god" objects are wrong?

  - by honestduane

  Problem Summary: Long story short, I inherited a code base and an development team I am not allowed to replace and the use of God Objects is a big issue. Going forward, I want to have us re-factor things but I am getting push-back from the teams who want to do everything with God Objects "because its easier" and this means I would not be allowed to re-factor. I pushed back citing my years of dev experience, that I'm the new boss who was hired to know these things, etc, and so did the third party offshore companies account sales rep, and this is now at the executive level and my meeting is tomorrow and I want to go in with a lot of technical ammo to advocate best practices because I feel it will be cheaper in the long run (And I personally feel that is what the third party is worried about) for the company. My issue is from a technical level, I know its good long term but I'm having trouble with the ultra short term and 6 months term, and while its something I "know" I cant prove it with references and cited resources outside of one person (Robert C. Martin, aka Uncle Bob), as that is what I am being asked to do as I have been told having data from one person and only one person (Robert C Martin) is not good enough of an argument. Question: What are some resources I can cite directly (Title, year published, page number, quote) by well known experts in the field that explicitly say this use of "God" Objects/Classes/Systems is bad (or good, since we are looking for the most technically valid solution)? Research I have already done: I have a number of books here and I have searched their indexes for the use of the words "god object" and "god class". I found that oddly its almost never used and the copy of the GoF book I have for example, never uses it (At least according to the index in front of me) but I have found it in 2 books per the below, but I want more I can use. I checked the Wikipedia page for "God Object" and its currently a stub with little reference links so although I personally agree with that it says, It doesn't have much I can use in an environment where personal experience is not considered valid. The book cited is also considered too old to be valid by the people I am debating these technical points with as the argument they are making is that "it was once thought to be bad but nobody could prove it, and now modern software says "god" objects are good to use". I personally believe that this statement is incorrect, but I want to prove the truth, whatever it is. In Robert C Martin's "Agile Principles, Patterns, and Practices in C#" (ISBN: 0-13-185725-8, hardcover) where on page 266 it states "Everybody knows that god classes are a bad idea. We don't want to concentrate all the intelligence of a system into a single object or a single function. One of the goals of OOD is the partitioning and distribution of behavior into many classes and many function." -- And then goes on to say sometimes its better to use God Classes anyway sometimes (Citing micro-controllers as an example). In Robert C Martin's "Clean Code: A Handbook of Agile Software Craftsmanship" page 136 (And only this page) talks about the "God class" and calls it out as a prime example of a violation of the "classes should be small" rule he uses to promote the Single Responsibility Principle" starting on on page 138. The problem I have is all my references and citations come from the same person (Robert C. Martin), and am from the same single person/source. I am being told that because he is just one guy, my desire to not use "God Classes" is invalid and not accepted as a standard best practice in the software industry. Is this true? Am I doing things wrong from a technical perspective by trying to keep to the teaching of Uncle Bob? God Objects and Object Oriented Programming and Design: The more I think of this the more I think this is more something you learn when you study OOP and its never explicitly called out; Its implicit to good design is my thinking (Feel free to correct me, please, as I want to learn), The problem is I "know" this, but but not everybody does, so in this case its not considered a valid argument because I am effectively calling it out as universal truth when in fact most people are statistically ignorant of it since statistically most people are not programmers. Conclusion: I am at a loss on what to search for to get the best additional results to cite, since they are making a technical claim and I want to know the truth and be able to prove it with citations like a real engineer/scientist, even if I am biased against god objects due to my personal experience with code that used them. Any assistance or citations would be deeply appreciated.

• Basic multicast network performance problems

  - by davedavedave

  I've been using mpong from 29west's mtools package to get some basic idea of multicast latency across various Cisco switches: 1Gb 2960G, 10Gb 4900M and 10Gb Nexus N5548P. The 1Gb is just for comparison. I have the following results for ~400 runs of mpong on each switch (sending 65536 "ping"-like messages to a receiver which then sends back -- all over multicast). Numbers are latencies measured in microseconds. Switch Average StdDev Min Max 2960 (1Gb) 109.68463 0.092816 109.4328 109.9464 4900M (10Gb) 705.52359 1.607976 703.7693 722.1514 NX 5548(10Gb) 58.563774 0.328242 57.77603 59.32207 The result for 4900M is very surprising. I've tried unicast ping and I see the 4900 has ~10us higher latency than the N5548P (average 73us vs 64us). Iperf (with no attempt to tune it) shows both 10Gb switches give me 9.4Gbps line speed. The two machines are connected to the same switch and we're not doing any multicast routing. OS is RHEL 6. 10Gb NICs are HP 10GbE PCI-E G2 Dual-port NICs (I believe they are rebranded Mellanox cards). The 4900 switch is used in a project with tight access control so I'm waiting for approval before I can access it and check the config. The other two I have full access to configure. I've looked at the Cisco document[2] detailing differences between NX-OS and IOS w.r.t multicast so I've got some ideas to try out but this isn't an area where I have much expertise. Does anyone have any idea what I should be looking at once I get access to the switch? [1] http://docwiki.cisco.com/wiki/Cisco_NX-OS/IOS_Multicast_Comparison

• Http-Only cookies in WebLogic: what versions support them/how and why are they supported?

  - by John

  We want to make all cookies set by our webapp http-only. I only have a basic understanding of the benefits of doing this but I'm told by security people that it's a Good Thing (tm) Our app is running under JDK1.6.05 and WebLogic10.3.0 After way too much digging around Oracle's website for documentation, I've found good evidence that the first version of WebLogic to support http-only cookies is 10.3.1. By "support," I mean the cookie-http-only deployment-descriptor element. Before we go about upgrading, I'd be nice to have these questions answered: 1a) Is it accurate that WL10.3.1 is the first version to support http-only cookies and that we're out of luck with 10.3.0? 1b) If we do indeed need to upgrade, is there an easy to do so under Windows? I've heard people mention an "upgrade jar" that you just stick in the classpath but I can't find any mention of this by Oracle. Does an easy way exist, or do we need to do a full-install of the new version? 2) What does the cookie-http-only deployment-descriptor element do when enabled? Will it ensure all cookies set by the application have an http-only=true attribute? Will it do more or less? Is there anything I'll have to do programmatically? 3) Is there anything in general I should know about http-only cookies, getting my web app to take advantage of them, or other security concerns?

• Stop Picasa (Mac) from scanning my harddrive

  - by Bodyscanner

  I want to use Picasa desktop app instead of the tedious & clunky web interface to share a couple of photos. Every time I launch Picasa it proceeds to open an annoying pop-up/tool-tip which flicks through every file on my HD using <=95% of CPU. I don't want this so I click the X. It appears again. I try to drag it somewhere less annoying onscreen but it pings back. I look in prefs for an option to turn it off. I give up and quit app until a new build comes out, which I download and repeat the above. WTF?! I understand Google can't be as cool as Apple - iPhoto isn't perfect by any means but at least it looks nice and 'just works'. I want to launch Picasa, not have it go through everything, not have 1000's of random pics and HD cruft on display in the list, and then perhaps drag in a few photos and upload them. Any idea of if that is possible? </rant>

• 32 core (each physical core) 2.2 GhZ or 12 core (6 physical cores) 3.0GHZ?

  - by Tejaswi Rana

  I am working on a multithreaded application (Forex trading app built on C#) and had the client upgrade from the 12 core 3.0GHZ machine (Intel) to a 32 core 2.2 Ghz machine (AMD). The PassMark benchmark results were significantly higher when using multicores doing Integer, Floating and other calculations while for a single core calculation it was a bit slower than the pack (others that were being compared to with similar config as the 12 core one). Oh it also comes with 64 GB RAM (4 times as the other one) and a much faster SSD. So after configuring and running the application on that machine, not only did it not perform as well, it was significantly slower. We're talking about 30seconds - 1 minute slower on an app that usually completes processing within 5-20 secs. The application uses MAX DEGREE of PARALLELISM (TPL) which I've tried setting to number of cores and also half of that. I've also tried running single threaded and without setting any limits in parallel threading. While it may be the hardware has some issues, I am wondering if the CPU processing speed is the issue. I can overclock to 3.0 GHZ. But is that even a good idea? Server Info - AMD http://www.passmark.com/forum/showthread.php?4013-AMD-Dual-6272-performance-is-60-lower-than-benchmarks Seems that benchmark was wrong to start with - officially. Intel i7 3930k OS (same in both) Windows 7 Professional 64-bit

• Can gnome windows (in Ubuntu) be individually themed?

  - by Peter.O

  (Yes, "individually themed" is an oxymoron, but I still want it.) I've just moved from Windows to Ubuntu Linux, and although I am enjoying this new adventure playground, I've encountered something quite unexpected... and its bugging me. It is probably because there are so many gnome apps in Ubuntu (... how strange :) This is great. and the range of available apps is excellent! ...but because of this one-stop-shop scenario, most of the windows look remarkably similar. I'm certainly not after bling-maximus, but I would like a few differentiating colours for my not-so-young eyes to help identify an app at a glance (especially in the compiz lists) ... I love compiz :) I thought it was just a bit of razzle-dazzle, and that alone would be enough, but it is actually very practical to boot. So, basically, I'm wondering if there is a way to theme individual window components on a per app basis... especially the window decoration; menu bar, etc. Thanks.
