• [SQL] How to SELECT TOP 5 and then the following 5?

  - by Crays

  Hi guys, as the comments always have it, you can select to show the top 5 comments (which i know how) and if there is more than 5, you can click a link and it will show the following 5 comments. The problem is that i don't know how the code should be for it to show the next 5. Better idea of what i'm saying Let's say i have 10 comments, i use SELECT * FROM news ORDER BY ID DESC LIMIT 5 that will show the TOP 5 comments say, the comments with ID 10,9,8,7,6 but what if i want the comments with ID 5,4,3,2,1 ?

• Why aren't Heroku syslog drains logging to rsyslogd?

  - by Benjamin Oakes

  I'm having a problem using syslog drains as described in https://devcenter.heroku.com/articles/logging. To summarize, I have an Ubuntu 10.04 instance on EC2 that is running rsyslogd. I've also set up the security groups as they describe, and added a syslog drain using a command like heroku drains:add syslog://host1.example.com:514. I can send messages from the Heroku console to my rsyslogd instance via nc. I see them appear in the log file, so I know there isn't a firewall/security group issue.  However, Heroku does not seem to be forwarding log messages to the server that heroku drains lists. I would expect to see HTTP requests, Rails messages, etc. Is there something else I can try to figure this out? I'm new to rsyslogd, so I could easily be missing something.

• Fusion 3.1 and Parallels 6 for Win7 x64

  - by Ronnie

  I read in a recent article that Parallels Desktop 6 is faster almost everywhere than VMware Fusion. I was originally using Parallels 4 before passing to VMware due to the frequent Parallels crashes. As now I am using a lot Fusion on my Macbook on a big Win7 x64 virtualized development machine that I find too slow I am wondering if the announced speed up of Parallels V6 is justified to come back to it. As a test I converted my Fusion 3.1 to a trial of Parallels Desktop 6 and my Windows Experience Index passed from 4.7 of Fusion to 4.5 on Parallels 6 so apparently the virtualized machine is not seeing that speed benefit. Is there any optimization to set up on Parallels to increase the WEI or should I stay with Fusion (and in this case this kind of articles is just marketing stuff)?

• portable usb harddisk regardless in windows and ubuntu / linux environment

  - by user8184

  I am doing web development mostly in ubuntu. Sometimes i need to go into windows to do other administrative work. Now i am ignorant about file systems. I cannot tell the difference between NTFS and FAT32. My eyes just glaze over the wikipedia articles. All I know is i have been using this 320 Gb portable USB harddisk to save files when I am in ubuntu and when I am in windows. Now i got a situation where sometimes the windows 7 cannot detect the harddisk. I believe it has to do with the file system issue. Or my harddisk is coming apart. To make it easy to backup my files in a portable USB harddisk regardless in ubuntu or windows, please advise me. That means i can go from from linux/ubuntu to portable harddisk read/write files from windows 7 to portable harddisk read/write files the same files. Thank you.

• Download a website that requires log-in with HTTtrack Copier

  - by H.Moss

  Hi guys! I have been researching of how to download content of a site that requires username and password. This is actually harder than I thought it would be. I tried to use both HTTtrack Copier and followed the instruction below, but it's not working! Q: I can not access several pages (access forbidden, or redirect to another location), but I can with my browser, what's going on? A: You may need cookies! Cookies are specific data (for example, your username or password) that are sent to your browser once you have logged in certain sites so that you only have to log-in once. For example, after having entered your username in a website, you can view pages and articles, and the next time you will go to this site, you will not have to re-enter your username/password. To "merge" your personnal cookies to an HTTrack project, just copy the cookies.txt file from your Netscape folder (or the cookies located into the Temporary Internet Files folder for IE) into your project folder (or even the HTTrack folder)

• Edit my message before posting in Twitter with Twitter API and PHP

  - by novellino

  I am having a site and I want to add a button in my site that will link to the twitter login page and after login it will post a message to the Twitter home page of the user.

• Single Exchange 2007 server - two AD domains

  - by TheCleaner

  CURRENT: single domain, single Exchange 2007 NEW: two domains, single Exchange 2007 Can this be done? Details: Current setup is a single W2k3 domain with a single Exchange 2007 server. We are merging with another company that currently hosts their email with their ISP via POP3. We'd like to start hosting their email on our Exchange server using their existing domain SMTP addresses. They don't have an AD domain at all at the moment. Recommendations? Can I do this with a trust between the 2 domains? Requirements: They can't have multiple SMTP addresses on both domains...such as I've seen with articles pointing to "hosting multiple domains". I want companyA to have the same account settings they've always had...companyB to have the same SMTP address they've had and not an additional one on the current companyA Exchange domain. They should be able to collaborate (calendar, contacts, GALs) but should still be distinguishable based on which company they "work for". Please help...thanks!

• Compiling Ruby on Mac OS X Snow Leopard

  - by gryzzly

  Hi, I am trying to follow this tutorial, on the subject of compiling ruby and rubygems on Snow Leopard: http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard I have added this to my ~/.profile: export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH" But if I write: echo $PATH I get: /opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/X11/bin But in tutorial it says: You should see /usr/local/bin at the beginning of the line returned by the system. I have installed macports sometime ago and plenty of other software, perhaps it has changed the path. Anyway, I have tried to proceed with the installation, so I have built ruby, I did: ./configure --enable-shared --enable-pthread CFLAGS=-D_XOPEN_SOURCE=1 make sudo make install cd .. But when I do which ruby I get: /usr/bin/ruby And according to the tutorial that's wrong. Also if I do ruby -v I get the older version of ruby that was preinstalled on Snow Leopard and not the one I've compiled. Thanks.

• Template error with django-photologue: 'Permission Denied'

  - by Ellie P.

  I'm in the process of re-setting up my Django development environment after reinstalling my OS. We use django-photologue with our project, which I installed using easy_install. However, I'm getting a template error on every template that has a photologue photo: TemplateSyntaxError at /newsroom/news/ Caught an exception while rendering: (13, 'Permission denied') One example of the line where the error is located: <img src="{{ photo.get_list_url }}"> I'm totally stumped--I've used photologue for this project on many different platforms and have never had this problem. Google yields nothing. I'm currently using Jolicloud (based on Ubuntu Jaunty). I'm working with a pre-existing database, so all of the photo sizes and everything have already been set up.

• Recommendations for a google finance-like interactive chart control

  - by Chris Farmer

  I need some sort of interactive chart control for my .NET-based web app. I have some wide XY charts, and the user should be able to interactively scroll and zoom into a specific window on the x axis. Something that acts similar to the google finance control would be nice, but without the need for the date labels or the news event annotations. Also, I'd prefer to avoid Flash, if that's even possible. Can someone please give some recommendations of something that might come close? EDIT: the "real" google timeline visualization is for date-based data. I just have numeric data. I tried to use that control for non-date data, but it seems to always want to show a date and demands that the first data column actually be a date.

• IBM storage ds3400 Cant connect to management using fiber

  - by Eli B

  i have a problem with a DS3400 IBM storage system we bought a few years back. when i try to manage the storage using its IBM storage management i cant find it using automatic detection even though its connected directly using the fiber and i can see the Logical drives connected and working properly. when i tried to connect the two management Ethernet wires and manage the storage directly by entering the IP address manually i am able to connect however after i make several changes to the controller configuration one of the controllers stops responding and i am not able to ping it directly (since you cant make any changes without being connected to both controllers this is a problem) whats more bizarre is that when i change the IP of the controller that doesn't respond it starts working .. i have found some articles over the web explaining stuff about LUN31 being missing and causing similar problems however all my attempts to manually configure it failed . *link to an example http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5075711 in short im trying to get my storage to appear in the storage manager when directly connected using only the fiber cable directly attached. thanks in advance

• Building a Data Warehouse

  - by Paul

  I've seen tutorials articles and posts on how to build datawarehouses with star and snowflakes schemas, denormalization of OLTP databases fact and dimension tables and so on. Also seen comments like: Star schemas are for datamarts, at best. There is absolutely no way a true enterprise data warehouse could be represented in a star schema, or snowflake either. I want to create a database that will server for reporting services and maybe (if that isn't enough) install analisys services and extract reports and data from cubes. My question was : Is it really necesarry to redesign my current database and follow the star/snowflake schemas with fact and dimension tables ? Thank you

• Full Backup & Restore for Windows Vista

  - by Thomas Matthews

  I'm looking for a freeware or low cost application that will backup everything, including registry on Windows Vista Home Premium and to restore from a CDROM disk. The destination is an external hard drive on USB 2.0. Searching on SuperUser and Stack Overflow show articles, but don't mention full backup of the registry and complete restore using CDROM. I would also like to have compressed output and incremental backups. One article mentions CloneZilla, but their web page says that the incremental feature is not supported. I am using Windows Vista Home Premium, Service Pack 1. I need to backup 200 GB onto a 230 GB drive and would like to have multiple backups (thus the need for compression). Other requirements: Single file restore Quality is more important than performance. Application must run on Windows Vista. Extra: Run as daemon or background task on 4 user system. Thanks

• How to Install two library CGNS for Fortran under WIndows XP

  - by user317368

  Hello, I have to install two libraries CGNS to use it in Fortan, but I don't understand how, the basic instructions are: To compile under MS Windows: configure.bat [options] then gmake if using GNU make, or nmake if using nmake. NOTE: This assumes that the cl compiler is in your path, and that the INCLUDE and LIB environment variables are set to include the directories containing the MSC include files and libraries. If not, you will need to use full path names to cl and link, and define INCLUDE and LIB in make.win32. You may also execute VCVARS32.BAT in the BIN directory of your VC installation to set these up prior to running nmake. so what i did was to: tape configure.bat it creates the rights files I set the news paths and lib, include for the cl.exe and link.exe but now the warning and error messages are about the clui.dll. cl -nologo -I. -Iadf -FoWIN32\cgns_error.obj -c cgns_error.c Cannot load language resource clui.dll what can i do now? I'm a beginner user in this field. Thankx Manal

• Monitoring Dell/HP Servers Running ESXi (Free)

  - by Untalented

  What are you all doing to monitor ESXi servers that run the free edition? With the lack of SNMP support, it seems fairly limited to me. What'd I'd like to be able to do is get some type of alert when a drive or other hardware fails. I've seen a few articles on getting OpenManage installed on an ESXi box (to rebuild an array), but it seems to be quite a pain as well. Even if I get OpenManage working, I won't have alerts without SNMP. Any comments, input, or guidance would be greatly appreciated.

  Hi forgive my ignorance for I am a humble client side developer... I am a webapp made up of static HTML and JS.

So I need to make a request to MY server http://dev.webapp.com/service So I want to redirect the /service on the server to http://externaldata.com/service And return the result. The Mac boys have acheived this in Apache with a proxy pass: ProxyPass /service http://externaldata.com/service Can anybody help with how to do this in IIS? I have found articles about ARRs and Reverse Proxy, terms that are alien and seem too complicated. As a humble webdev can I do this using IIS GUI?

• how to manually add a cookie to Mechanize state?

  - by fearless_fool

  [I'm working in Ruby, but my question is valid for other languages as well.] I have a Mechanize-driven application. The server I'm talking to sets a cookie using javascript (rather than standard set-cookie), so Mechanize doesn't catch the cookie. I need to pass that cookie back on the next GET request. The good news is that I already know the value of the cookie, but I don't know how to tell Mechanize to include it in my next GET request. Pointers or suggestions are welcome. Thanks in advance. -ff

• Restoring Box Sync (box.com) using physical media after OS reinstall

  - by sjrm

  I have my Box Folder on a different drive ( D: ) than my Operating System Drive ( C: ) I follow these instructions to set the local folder on the second drive. https://support.box.com/hc/en-us/articles/200852947-How-Can-I-Change-the-Default-Folder-Location-for-Box-Sync- I had to format and reinstall Windows 7, leaving the other drive (D: ) untouched. now i reinstalled Box Sync, and directed it to the same location where i already have all my files. However, Box Sync renamed the folder to (Box ([email protected]) ) as a bckup, and is downloading everything again. As i have like 30Gb of files, and it takes many hour to download them, i just want to use the files that i already have in my local disk. i tried copying all files again to the new local Box Folder, but files started to get duplicated. Is there any way to avoid downloading everything again each time i reinstall my OS ? Thanks

• search engine crawling frequency

  - by Aditya Pratap Singh

  I want to design a search engine for news websites ie. download various article pages from these websites, index the pages, and answer search queries on the index. I want a short pseudocode to find an appropriate crawling frequency -- i do not want to crawl too often because the website may not have changed, and do not want to crawl too infrequently because index would then be out of date. Assume that crawling code looks as follows while(1) { sleep(sleep_interval); // sleep for sleep_interval crawl(website); // crawls the entire website diff = diff(currently_crawled_website, previously_crawled_website); // returns a % value of difference between the latest and previous crawls of the website sleep_interval = infer_sleep_interval(diff, sleep_interval); } looking for a pseudocode for the infer_sleep_interval method: long sleep_interval infer_sleep_interval(int diff_percentage,long previous_sleep_interval) { ... ... ... } i want to design method which adaptively alters the sleeping interval based on the update frequency of the website.

• Customize subtitles for QuickTime + Perian

  - by Kit

  How do I customize the display of subtitles (e.g. font, size, color, outline, drop shadow) in QuickTime + Perian? I've seen articles on how to do it but it requires Jubler to edit the subtitles. Is there a straightforward way to customize the subtitles within QuickTime or Perian? If there isn't any, what are other alternatives? VLC can't display drop shadows, and can customize the outline. I'm looking for other ways where I'll only have to use QuickTime.

• Forwarding wifi traffic to wired pc

  - by brydgesk

  I'm trying to play around with Wireshark on my home network, and was wondering if there is a way to create a new connection on my PC that receives all wifi packets on the network. The PC is a wired Windows 7 machine, and I'm using DD-WRT on an Asus RT-N16 router. I'm not trying to hack anything, I have full admin access to the router itself. My searching has led me to articles about client bridges and repeater bridges, but none of them seemed to apply entirely to my situation. I'd like to continue using my standard wifi connection, but make my PC act as a repeater that receives all wifi traffic. Again, the PC has no wireless connection. I've used tcpdump which is installed on the router itself, but I'd be more comfortable analyzing the packets in Windows, as I'm trying to learn Wireshark. Thanks
