• Software for formatting / web-publishing tutorial-type, technical articles

  - by gojira

  I want to put some of my own technical writing on the web: tutorials, how-to's, conceptual articles about programming etc. I write mostly for myself yet, but think others can benefit from it so I want to put it online, and I also have plans of making everything more coherent and turning it into a book. My articles are not meant as a blog, they're just meant as a collection of tutorials and how-to's, but I think a blog-type software would probably be the most appropriate mode of formatting that kind of stuff. Right now I am using the blog feature of cite u like, which is very low tech and I really need something better. On my wish list is, among other things: code snippets in scrollable boxes syntax highlighting for source code snippets tagging articles with graphical icons according to topic, like in slashdot of course users (i.e. readers) should be able to comment on articles Also, just more options than a super-simple blog should look slick! should not look wikipedia-like Is there any software you can recommend for this purpose?

• Spiceworks versus Request Tracker?

  - by dmackey

  We currently utilize Request Tracker for help desk ticketing, we utilize Spiceworks for asset inventorying. I am pondering whether it might be worthwhile to move from RT to Spiceworks for help desk as well. Has anyone used both systems and can provide some insight into any benefits/problems with either system? Or has general philosophical reasons why one should use one solution over the other? Of course, RT is open source and Spiceworks is not - and usually this would be a major item for me - but since Spiceworks is free and takes community involvement fairly actively its not as major of a concern for me (personally).

• You Don't Want to Meet Orgad Kimchi in a Dark Alley

  - by rickramsey

  source Do you remember what those bad guys in the old Charles Bronson films looked like? They looked like Orgad Kimchi, that's what they looked like. When I met him at Oracle OpenWorld 2012, I realized I didn't want to meet him in the wrong alleyway of Budapest after dark. Neither do old versions of Oracle Solaris, which Orgad bends to his will with as much ease as he probably bends stray tourists to his will in Budapest, Kandahar, or Dagestan. How Orgad Made Oracle Database Migrate from Oracle Solaris 8 to Oracle Solaris 11 In this article, which we liked so much we reprinted it from his blog (please don't tell him!), Orgad explains how he head-butted an Oracle Database into submission. The database thought it was safe running in Oracle Solaris 8, but Orgad dragged its whimpering carcas into Oracle Solaris 11. How'd he do that? Well, if you had met Orgad in person, you wouldn't ask that question. Because you'd know he could have simply stared at it, and the database would have migrated on its own. But Orgad didn't do that. Instead, he stuffed an Oracle Solaris 8 Physical-to-Virtual (P2V) Archiver Tool into his leather trench coat, the one with the special pockets sown in by the East German Secret Police for several Uzis and their ammo, and walked into his data center in a way that reminded the survivors of this clip from Matrix Reloaded. The end result? The Oracle Database 10.2 that was running on Oracle Solaris 8 is now running inside a Solaris 10 branded zone in Oracle Solaris 11. With no complaints. Don't make Orgad angry.

• Groovy Debugging

  - by Vijay Allen Raj

  Groovy Debugging - An Overview:ADF BC developers may express snippets of business logic (like the following) as embedded groovy expressions: default / calculated attribute valuesvalidation rules / conditionserror message tokensLOV input values (VO) This approach has the advantages that: Groovy has a compact, EL-like syntax for expressing simple logicADF has extended this syntax to provide useful built-insembedded Groovy expressions are customizableGroovy debugging support helps improve maintainability of business logic expressed in Groovy.Following is an example how groovy debugging works.Example:This example shows how a script expression validator can be created and the groovy script debugged. It shows Step over, breakpoint functionalities as well as syntax coloring.Let us create a ADFBC application based on Emp and Dept tables, and add a script expression validator based on the script:  if (Sal >= 5000){ //If EmpSal is greater than a property value set on the custom //properties on the root AM //raise a custom exception else raise a custom warning if (Sal >= source.DBTransaction.rootApplicationModule.propertiesMap.salHigh) { adf.error.raise("ExcGreaterThanApplicationLimit"); } else { adf.error.warn("WarnGreaterThan5000"); } } else if (EmpSal <= 1000) { adf.error.raise("ExcTooLow"); }return true;In the Emp.xml Flat editor, place breakpoints at various locations as shown below:Right click the appmodule and click Debug. Enter a value greater than 5000 and click next. You can see the debugging work as shown below:  The code can be also be stepped over and debugged.

• Only allow certain processes to connect to MS SQL

  - by Fred

  I've lost the source code for a very old application that connects to a MS SQL-server for some SQL queries. Since the login is hard-coded in the application I can't change the username/password on the server. One day the password will probably be known to the users and we surely need to change it. But how? One idea is to only allow the old application to do the queries on the SQL server and block out any other application like the query analyzer etc. Can I set process permission somehow? The SQL server (MS SQL 2005) and application (C++) are on the same machine It's too costly to rewrite the old program Thanks for help!

• CEO Taken Captive in His Own Factory?

  - by Stephen Slade

  Last Friday was no ordinary day for Chip Starnes, the 42 year old factory owner of Specialty Medical Supplies in China. He recently announced movement of some of the production of their diabetes testing equipment from Beijing to Mumbai India.  Of the 110 employees at the facility, about 80 protested by blocking the doors and refusing to let Chip Starnes out of the facility.  He has been trapped in his office several days now.  The employees think the factory was closing but Mr. Starnes said it was not. Mis-information? Poor communications? Work-stoppage. This is a good example of supply chain disruption. Parked cars are blocking the entrance to the facility, front gates are chained close, the CEO a prisoner in his own factory. Chip Starnes was presented with documents to sign in Chinese indicating he would pay severance and other demands he did not understand, possibly bankrupting the company.    If you depend on supply from China and other foreign suppliers, how reliable are your sources? For example how are the shopfloor employee relations? Is it possible to predict these types of HR risks and plan around them? What are your contingencies? It's important to ask the right questions and hear good answers. Having tools in place to rapidly evaluate, assess and react to these disruptions are the keys to survival. Hear how leading organizations are reinforcing their supply chains and mitigating risk through technology with Oracle's latest release of Oracle Supply Chain Management.

• Tools to automate recording streaming radio

  - by Stan

  Is there any tool that can automate recording online streaming radio? I've been use totalrecorder which it has below upside: 1. Handy scheduler. 2. Support create recording templates, so I can customize some high/low quality recording. The downside are it requires to open the streaming radio in browser and can't have another sound source. It's recording what comes out from the speaker. What I am looking for is given a online radio url, and the tool can record the audio stream. No matter if I am playing any other music or not. Thanks.

• Setting up mutt for gmail

  - by highBandWidth

  I am trying to set up mutt for gmail. I am following instructions at http://crunchbanglinux.org/wiki/howto/howto_setup_mutt_with_gmail_imap, however, after putting set from = "[email protected]" set realname = "Your Real Name" set imap_user = "[email protected]" set imap_pass = "yourpassword" (with my details, of course), I get $ mutt Error in $HOME/.muttrc, line 12: imap_user: unknown variable Error in $HOME/.muttrc, line 13: imap_pass: unknown variable source: errors in $HOME/.muttrc Press any key to continue... If I try to send an email, it doesn't work because instead of IMAP, it tries to send email directly from my localhost's mail system. Mutt says it is version Mutt 1.4.2.3i.

• Any good software to help me memorize passwords?

  - by Septagram

  I'm using KeePass(X) and other tools to keep most of my passwords. However, it turns out, there is still about half a dozen passwords I'm using on regular basis that I would prefer to just remember. So, do you people know of any good programs, preferably open-source, to train yourself using a particular password and thus to memorize it? I know I can remember a 96-bit entropy password rather well if I practice entering it 3 days, 5 minutes for each day, I just want a good software to simplify the process and exclude the possibility of shouldering or otherwise leaking the password.

• Good, secure video chat program

  - by wag2639

  I'm looking for something similar to skype but basically just for me to video chat with my girlfriend. Skype has been kind of buggy lately with its recent iterations and doesn't seem to be progressing as much as when it was with its previous backers. Are there any good, secure video chat programs? Something that customizable and lets you choose framerate vs pixelation and is generally secure (I don't care if the NSA can tap it but no one else, especially over unencrypted wifi's). Open source is preferred but not required. Free or really really cheap is practically required. Also, since this is point to point, an i am a power user (and my gf as well), it can involve some manual setup to establish a point-to-point link. Any suggestions, Thanks.

• How do I get OBDII software working?

  - by NoBugs

  I have an ODBII USB cable for vehicle diagnostics, unfortunately I haven't been able to get it working on Ubuntu 12.04. The closest I've come is using the VAG-COM software with wine, using the ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1 trick and running stty -F /dev/ttyUSB0 speed 9600 repeatedly. It will connect and show the vehicle is OBDII, but none of the useful features seem to be working. I tried: Scantool - says it's connecting to the /dev/device in terminal, but doesn't. obdgpslogger - times out all the time. pyobd - This seems to be the most up-to-date source I could find, I had to adjust the code a bit to work (see here for changes). Still, in obd_io.py interpret_result function, it says it's looking for 4 space separated numbers, where the usb-serial is receiving bogus code "0100" instead? The device shows up in lsusb as: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Is the problem that these native tools don't expect a USB serial, or a serial of this type? Or are these apps too old to recognize OBD2 of this vehicle?

• Cost effective way to provide static media content

  - by james

  I'd like to be able to deliver around 50MB of static content, either in about 30 individual files up to 10MB or grouped into 3 compressed files, around 5k to 20k times a day. Ideally I'd like to put some sort of very basic security around providing the data to ensure that a request is from the expected source, but if tossing the security for a big reduction in price is possible then it's an option. Does anyone have any suggestions other than what I've found: Google AppEngine is $0.12/GB & I believe has a file size limit of 10MB so I'd have to break the data up a bit. So a rough calculation would seem to be that this would cost me about $30 to $120 a day. Or I've seen something like what seems to be just public static content delivery with no type of logic capabilities like Usenet.nl at what I think calculates to about $0.025/GB which would cost me about $6 to $25 a day. Any idea if I'm going about these calculations right & if there might be a better option for just static content on a decently high volume delivery? Again some basic security would be great but if cost is greatly reduced without it then I'm up for that.

• Why is mcrypt not included in most Linux distributions?

  - by Daniel Lopez

  libmcrypt is a powerful encryption library that is very popular with PHP-based applications. However, most Linux distributions do not include it. This causes problems for many users that need to download and compile it separately. I am guessing that the reason it is not shipped is related to encryption or patent issues. However, the source code for library itself is hosted and available on sourceforge.net I have been searching unsuccessfully for a document of authoritative post that explains the exact issues why this extension is not bundled with mainstream distributions. Can anyone provide a pointer to such material or provide an explanation?

• Who is code wanderer?

  - by DigiMortal

  In every area of life there are people with some bad habits or misbehaviors that affect the work process. Software development is also not free of this kind of people. Today I will introduce you code wanderer. Who is code wanderer? Code wandering is more like bad habit than serious diagnose. Code wanderers tend to review and “fix” source code in files written by others. When code wanderer has some free moments he starts to open the code files he or she has never seen before and starts making little fixes to these files. Why is code wanderer dangerous? These fixes seem correct and are usually first choice to do when considering nice code. But as changes are made by coder who has no idea about the code he or she “fixes” then “fixing” usually ends up with messing up working code written by others. Often these “fixes” are not found immediately because they doesn’t introduce errors detected by compilers. So these “fixes” find easily way to production environments because there is also very good chance that “fixed” code goes through all tests without any problems. How to stop code wanderer? The first thing is to talk with person and explain him or her why those changes are dangerous. It is also good to establish rules that state clearly why, when and how can somebody change the code written by other people. If this does not work it is possible to isolate this person so he or she can post his or her changes to code repository as patches and somebody reviews those changes before applying them.

• Problem in listening to multicast in multihomed Linux server

  - by Lior

  I am trying to write a multicast client on a machine with two NICs, and I can't make it work. I can see with a sniffer that once I start the program the NIC (eth4) start receiving the multicast datagrams: y.y.y.y. (some ip) - z.z.z.z (multicast ip, not my eth4 NIC IP) UDP Source port: kkk (some other port) Destination port: xxx (multicast port) However, I can't get those packets using my program (listening to port xxx on eth4). I also added: route add 224.0.0.0 netmask 240.0.0.0 dev eth4 Searched the web for some examples/explanations, but it seems like I do what everybody else does. Any help will be appreciated. is there anything else to do with route/iptables?

• Plus signs appearing in Google searches

  - by emddudley

  Ever since Google implemented their new look at the beginning of May, I have been having trouble with their search engine changing all of the spaces in my query to plus signs. This behavior occurs when I use the search box in both Firefox and Internet Explorer. For example, if I search for google search plus signs I am taken to the following URL, where google+search+plus+signs is in the search box. http://www.google.com/search?q=google+search+plus+signs&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a However if I perform the search from google.com, I get taken to a different URL with google search plus signs as I'd expect: http://www.google.com/#hl=en&source=hp&q=google+search+plus+signs&aq=f&aqi=g1&aql=&oq=&gs_rfai=&fp=d2a3ca21987adb1 Do I need to update my browsers or something?

• Replicating/Synchronizng multiple tables across diffrent Databases on the same instance

  - by Idan

  I have few tables that needed to be replicated/synchronized across several databases in our SQL Server 2008 cluster. I know it's possible to replicate between multiple instances, but I'm looking for replication or synchronization in the same instance between specific tables of databases. The replicaiton/synchronization should happen every half-hour or so, but I don't mind it happening constantly. I can't use DROP the target table and INSERT (copy) the source table since there are many constraints. Reason for this is to not manage in the application layer and write to 2 different databases at the same time. Example: DB1 has T1, T2 and T3 - these are constantly being updated by the application, APP1 running on DB1. DB2 needs to have an updated copy of T1 at all times, also, there is a different application, APP2 runs only on DB2. Both DB1 and DB2 are located on the same instance, INST1. Would it be possible to replicate T1, T2 and T3 from DB1 to DB2 ? Thanks, Idan.

• How to set up Dell OMSA tools on Debian 6 (Squeeze) (PE2950)

  - by javano

  I assume I have set up them up incorrectly or am missing a library or dependency. When I log into the OMSA web interface I can't see anything Also, omreport tells me nothing; root@box:~# omreport storage controller No controllers found I assume these two will use the same source of information so what ever is wrong will fix them both. I set up OMSA as per these instructions. Also I have compiled MegaCLI (as this is a PowerEdge 2950 with a Perc 6/i controller) and I have used that to update the RAID firmware, so that works, but the Dell tools aren't. What have I missed during set up? root@kvm1:~# cat /etc/issue Debian GNU/Linux 6.0 \n \l root@kvm1:~# uname -a Linux kvm1.mivoice.cust.vostron.net 3.4.9 #1 SMP Wed Aug 22 19:08:46 BST 2012 x86_64 GNU/Linux

  Raj, the Chennai JUG lead, together with others from that JUG, is interested in Visage, the JavaFX script language closely associated with Stephen Chin. He sent me the related lexer and parser and I started by having a look at them in the new version of ANTLRWorks being developed by Sam Harwell (who demonstrated it very effectively during JavaOne): Notice how the lexer and parser are shown in a tree structure, as well as in a cool syntax diagram. Next, I downloaded a bunch of JARs from here, so that packages such as from "com.sun.tools.mjavac" can be used, i.e., these are Visage-specific packages that aren't found anywhere except in the location below: http://code.google.com/p/visage/wiki/GettingStarted It turns out that there's also a Visage NetBeans plugin out there: http://code.google.com/p/visage/source/browse/?repo=netbeans-plugin Rather than recreating everything from scratch, i.e., generating ANTLR Java classes from the lexer and parser, I copied a lot of stuff from the site above and now a file Raj sent me looks as follows, i.e., basic syntax coloring is shown: For anyone wanting to seriously support Visage in NetBeans IDE, I recommend downloading the existing Visage NetBeans plugin above, rather than creating everything yourself from scratch, and then figuring out how to use that code in some way, i.e., add the JARs I pointed to above, and work on its build.xml file, which could be frustrating in the beginning, but there's no point in recreating everything if everything already exists.

• We're Subversion Geeks and we want to know the benefits of Mercurial

  - by Matt

  Having read I'm a Subversion geek, why should I consider or not consider Mercurial or Git or any other DVCS. I have a related follow up question. I read that question and read the recommended links and videos and I see the benefits but I don't see the overall mindshift people are talking about. Our team is of 8-10 developers that work on one large code base consisting of 60 projects. We use Subversion and have a main trunk. When a developer starts a new Fogbugz case they create a svn branch, do the work on the branch and when they're done they merge back to the trunk. Occasionally they may stay on the branch for an extended time and merge the trunk to the branch to pick up the changes. When I watched Linus talk about people creating a branch and never doing it again, that's not us at all. We create probably 50-100 branches a week without issue. The biggest challenge is the merging but we've gotten pretty good at that as well. I tend to merge by fogbugz case & checkin rather than the entire root of the branch. We never work remotely and we never make branches off of branches. If you're the only one working in that section of the code base then the merge to the trunk goes smoothly. If someone else had modified the same section of code then the merge can get messy and you might need to do some surgery. Conflicts are conflicts, I don't see how any system could get it right most of the time unless if was smart enough to understand the code. After creating a branch the following checkout of 60k+ files takes some time but that would be an issue with any source control system we'd use. Is there some benefit of any DVCS that we're not seeing that would be of great help to us?

• Finding a way to simplify complex queries on legacy application

  - by glenatron

  I am working with an existing application built on Rails 3.1/MySql with much of the work taking place in a JavaScript interface, although the actual platforms are not tremendously relevant here, except in that they give context. The application is powerful, handles a reasonable amount of data and works well. As the number of customers using it and the complexity of the projects they create increases, however, we are starting to run into a few performance problems. As far as I can tell, the source of these problems is that the data represents a tree and it is very hard for ActiveRecord to deterministically know what data it should be retrieving. My model has many relationships like this: Project has_many Nodes has_many GlobalConditions Node has_one Parent has_many Nodes has_many WeightingFactors through NodeFactors has_many Tags through NodeTags GlobalCondition has_many Nodes ( referenced by Id, rather than replicating tree ) WeightingFactor has_many Nodes through NodeFactors Tag has_many Nodes through NodeTags The whole system has something in the region of thirty types which optionally hang off one or many nodes in the tree. My question is: What can I do to retrieve and construct this data faster? Having worked a lot with .Net, if I was in a similar situation there, I would look at building up a Stored Procedure to pull everything out of the database in one go but I would prefer to keep my logic in the application and from what I can tell it would be hard to take the queried data and build ActiveRecord objects from it without losing their integrity, which would cause more problems than it solves. It has also occurred to me that I could bunch the data up and send some of it across asynchronously, which would not improve performance but would improve the user perception of performance. However if sections of the data appeared after page load that could also be quite confusing. I am wondering whether it would be a useful strategy to make everything aware of it's parent project, so that one could pull all the records for that project and then build up the relationships later, but given the ubiquity of complex trees in day to day programming life I wouldn't be surprised if there were some better design patterns or standard approaches to this type of situation that I am not well versed in.
