• "Oracle", "Sybase", "SQL Server" vs just "SQL/JDBC" in the CV

  - by bobah

  How would you define a testable measure of the expertise that, if you're honest with yourself, lets you write in your CV words "Oracle", "Sybase", or "SQL Server" and not just "Relational Databases, SQL, JDBC" in your software developer's CV? What every XXX-developer (XXX - a vendor name) should know? The question is similar to http://stackoverflow.com/questions/2119859/questions-every-good-database-sql-developer-should-be-able-to-answer but is vendor-specific. Below is a start of the list as an example, demonstrate what kind of answers I am hoping to get. If you are expert in X then you know that Y (X - Y below): Sybase/SQL Server - they are very similar, Sybase is much more expensive Sybase/SQL Server - for Java you can use either native Sybase/JSQLDB driver or jTDS that is using TDS protocol and can connect to SQL Server as well, TDS traffic can be dumped and analyzed with hexdump command Sybase/SQL Server - for C++ you can use FreeTDS to connect to any, for Perl - same Sybase/SQL Server - a query can return multiple result sets and return codes, all need to be processes otherwise errors can happen Sybase/SQL Server - sp_help, sp_helptext Sybase/SQL Server - your tables/views/procedures are under DBName/dbo/... Sybase - for C++ on Linux you can use Sybase client API to connect (at least until recently) SQL Server - JDBC driver has a configurable transparent failover capability Oracle - for C++ Linux one can use OTLv4 that is a very powerful yet lightweight wrapper around Oracle client API Oracle compilation (contributors: ammoQ) PLSQL Java Stored Procedures '' is null Hierarchical Query Analytic Functions Oracle Text

• What is spreadsheet useful for?

  - by zvrba

  I have been in computer business for 15 years in various roles (sysadmin, developer, researcher), and I have never encountered someone using excel for something more advanced than for formatting tables, or as an ad-hoc database that could have been maintained in a text-file. I had to do heavy data-processing and plotting and for that I used some perl scripts + gnuplot, got tiredof it, and went over to R eventually. 2D spreadsheet just didn't seem well-suited for doing statistical analyses over 5-dimensional datasets (not to mention that it produces UGLY plots). I attempted to use spreadsheet for time-tracking, and found out that I would have better been served by a relational database, so I gave up on using excel for that too. For example, it's important to consistently name tasks, and I needed to find out unique task names in a given column across several sheets (I had one timesheet for each month). How do you make such "query" in a program that essentially evaluates independent cells and has little notion of relations between them? So, what are spreadsheets useful for? Why do they have a bunch of mathematical stuff built into them when, AFAICT, people use them mostly as table formatters or bad substitutes for databases?

• How to solve package issues/dependencies

  - by Wolfgang Kuehne

  Background info I am trying to install Veins simulation environment by following the tutorial provided by the author. In step 1 it is required to install some packages in Linux, the tutorial suggest this commands to be executed on Terminal: sudo apt-get install build-essential gcc g++ bison flex perl tcl-dev tk-dev blt libxml2-dev zlib1g-dev default-jre doxygen graphviz libwebkitgtk-1.0-0 openmpi-bin libopenmpi-dev libpcap-dev autoconf automake libtool libxerces-c2-dev proj libgdal1-dev libfox-1.6-dev When I execute this command, I immediately get: E: Package 'proj' has no installation candidate Then I remove the proj from the command and execute it again without proj in it, next I get: The following packages have unmet dependencies: libgdal1-dev : Depends: libgdal-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages. So, I remove libgdal1-dev from the command as well. And it executes file, by downloading the remaining packages. To troubleshoot the problem with proj and libdgal1-dev I go to the Synaptic Package Manager. libgdal1-dev I search for libgdal1-dev in Synaptic Package Manager and I get an entry. I Mark for Installation and then Synaptic Package Manager suggests removing libxerces-c2-dev which is actually added via the initial command. Should I trust Synaptic Package Manager with this suggestion, and proceed further? proj What should I do about proj. There are some packages in Synaptic Package Manager such as proj-bin or libproj-dev. Should I install them? I think proj has to do with this and this What should I do to make sure that this simulation tool works fine?

• New Regular Expression Features in Java 8

  - by Jan Goyvaerts

  Java 8 brings a few changes to Java’s regular expression syntax to make it more consistent with Perl 5.14 and later in matching horizontal and vertical whitespace. \h is a new feature. It is a shorthand character class that matches any horizontal whitespace character as defined in the Unicode standard. In Java 4 to 7 \v is a character escape that matches only the vertical tab character. In Java 8 \v is a shorthand character class that matches any vertical whitespace, including the vertical tab. When upgrading to Java 8, make sure that any regexes that use \v still do what you want. Use \x0B or \cK to match just the vertical tab in any version of Java. \R is also a new feature. It matches any line break as defined by the Unicode standard. Windows-style CRLF pairs are always matched as a whole. So \R matches \r\n while \R\R fails to match \r\n. \R is equivalent to (?\r\n|[\n\cK\f\r\u0085\u2028\u2029]) with an atomic group that prevents it from matching only the CR in a CRLF pair. Oracle’s documentation for the Pattern class omits the atomic group when explaining \R, which is incorrect. You cannot use \R inside a character class. RegexBuddy and RegexMagic have been updated to support Java 8. Java 4, 5, 6, and 7 are still supported. When you upgrade to Java 8 you can compare or convert your regular expressions between Java 8 and the Java version you were using previously.

• Is there an alternative to Google Code Search?

  - by blunders

  Per the Official Google Blog: Code Search, which was designed to help people search for open source code all over the web, will be shut down along with the Code Search API on January 15, 2012. Google Code Search is now gone, and since that makes it much harder to understand the features it presented, here's my attempt to render them via information I gathered from a cache of the page for the Search Options: The "In Search Box" just notes the syntax to type the command directly in the main search box instead of using the advance search interface. Package (In Search Box: "package:linux-2.6") Language (In Search Box: "lang:c++") (OPTIONS: any language, actionscript, ada, applescript, asp, assembly, autoconf, automake, awk, basic, bat, c, c#, c++, caja, cobol, coldfusion, configure, css, d, eiffel, erlang, fortran, go, haskell, inform, java, java, javascript, jsp, lex, limbo, lisp, lolcode, lua, m4, makefile, maple, mathematica, matlab, messagecatalog, modula2, modula3, objectivec, ocaml, pascal, perl, php, pod, prolog, proto, python, python, r, rebol, ruby, sas, scheme, scilab, sgml, shell, smalltalk, sml, sql, svg, tcl, tex, texinfo, troff, verilog, vhdl, vim, xslt, xul, yacc) File (In Search Box: "file:^.*.java$") Class (In Search Box: "class:HashMap") Function (In Search Box: "function:toString") License (In Search Box: "license:mozilla") (OPTIONS: null/any-license, aladdin/Aladdin-Public-License, artistic/Artistic-License, apache/Apache-License, apple/Apple-Public-Source-License, bsd/BSD-License, cpl/Common-Public-License, epl/Eclipse-Public-License, agpl/GNU-Affero-General-Public-License, gpl/GNU-General-Public-License, lgpl/GNU-Lesser-General-Public-License, disclaimer/Historical-Permission-Notice-and-Disclaimer, ibm/IBM-Public-License, lucent/Lucent-Public-License, mit/MIT-License, mozilla/Mozilla-Public-License, nasa/NASA-Open-Source-Agreement, python/Python-Software-Foundation-License, qpl/Q-Public-License, sleepycat/Sleepycat-License, zope/Zope-Public-License) Case Sensitive (In Search Box: "case:no") (OPTIONS: yes, no) Also of use in understanding the search tool would be the still live FAQs page for Google Code Search.

• What are Web runtime environments and programming languages

  - by Bradly Spicer

  I've been looking into the details behind these two different categories: Web runtime environments Web application programming languages I believe I have the correct information and have phrased it correctly but I am unsure. I have been searching for a while but only find snippets of information or what I can see as useless information (I could be wrong). Here are my descriptions so far: Web runtime environments - A Run-time environment implements part of the core behaviour of any computer language and allows it to be modified via an API or embedded domain-specific language. A web runtime environment is similar except it uses web based languages such as Java-script which utilises the core behaviour a computer language. Another example of a Run-time environment web language is JsLibs which is a standable JavaScript development runtime environment for using JavaScript as a general all round scripting language. JavaScript is often used to create responsive interfaces which improve the user experience and provide dynamic functionality without having to wait for the server to react and direct to another page. Web application programming languages - A web application program language is something that mimics a traditional desktop application within a web page. For example, using PHP you can create forms and tables which use a database similar to that of Microsoft Excel. Some of the other languages for web application programming are: Ajax Perl Ruby Here are some of the resources used: http://en.wikipedia.org/wiki/Web_application_development http://code.google.com/p/jslibs/ I would like some confirmation that the descriptions I have created are correct as I am still slightly unsure as to whether I have hit the nail on the head.

• Do you think natively compiled languages have reached their EOL?

  - by Yuval A

  If we look at the major programming languages in use today it is pretty noticeable that the vast majority of them are, in fact, interpreted. Looking at the largest piece of the pie we have Java and C# which are both enterprise-ready, heavy-duty, serious programming languages which are basically compiled to byte-code only to be interpreted by their respective VMs (the JVM and the CLR). If we look at scripting languages, we have Perl, Python, Ruby and Lua which are all interpreted (either from code or from bytecode - and yes, it should be noted that they are absolutely not the same). Looking at compiled languages we have C which is nowadays used in embedded and low-level, real-time environments, and C++ which is still alive and kicking, when you want to get down to serious programming as close to the hardware as you can, but still have some nice abstractions to help you with day to day tasks. Basically, there is no real runner-up compiled language in the distance. Do you feel that languages which are natively compiled to executable, binary code are a thing of the past, taken over by interpreted languages which are much more portable and compatible? Does C++ mark an end of an era? Why don't we see any new compiled languages anymore? I think I should clarify: I do not want this to turn into a "which language is better" discussion, because that is not the issue at hand. The languages I gave as example are only examples. Please focus on the question I raised, and if you disagree with my statement that compiled languages are less frequent these days, that is totally fine, I am more than happy to be proved mistaken.

• Managing JS and CSS for a static HTML web application

  - by Josh Kelley

  I'm working on a smallish web application that uses a little bit of static HTML and relies on JavaScript to load the application data as JSON and dynamically create the web page elements from that. First question: Is this a fundamentally bad idea? I'm unclear on how many web sites and web applications completely dispense with server-side generation of HTML. (There are obvious disadvantages of JS-only web apps in the areas of graceful degradation / progressive enhancement and being search engine friendly, but I don't believe that these are an issue for this particular app.) Second question: What's the best way to manage the static HTML, JS, and CSS? For my "development build," I'd like non-minified third-party code, multiple JS and CSS files for easier organization, etc. For the "release build," everything should be minified, concatenated together, etc. If I was doing server-side generation of HTML, it'd be easy to have my web framework generate different development versus release HTML that includes multiple verbose versus concatenated minified code. But given that I'm only doing any static HTML, what's the best way to manage this? (I realize I could hack something together with ERB or Perl, but I'm wondering if there are any standard solutions.) In particular, since I'm not doing any server-side HTML generation, is there an easy, semi-standard way of setting up my static HTML so that it contains code like <script src="js/vendors/jquery.js"></script> <script src="js/class_a.js"></script> <script src="js/class_b.js"></script> <script src="js/main.js"></script> at development time and <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script> <script src="js/entire_app.min.js"></script> for release?

• Can Foswiki be used as a distributed Redmine replacement? [closed]

  - by Tobias Kienzler

  I am quite familiar with and love using git, among other reasons due to its distributed nature. Now I'd like to set up some similarly distributed (FOSS) Project Management software with features similar to what Redmine offers, such as Issue & time tracking, milestones Gantt charts, calendar git integration, maybe some automatic linking of commits and issues Wiki (preferably with Mathjax support) Forum, news, notifications Multiple Projects However, I am looking for a solution that does not require a permanently accesible server, i.e. like in git, each user should have their own copy which can be easily synchronized with others. However it should be possible to not have a copy of every Project on every machine. Since trac uses multiple instances for multiple projects anyway, I was considering using that, but I neither know how well it adapts to simply giting the database itself (which would be be easiest way to handle the distribution due to git being used anyway), nor does it include all of Redmine's feature. After checking http://www.wikimatrix.org for Wikis with integrated tracking system and RCS support, and filtering out seemingly stale project, the choices basically boil down to Foswiki, TWiki and Ikiwiki. The latter doesn't seem to offer as many usability features, and in the TWiki vs Foswiki issue I tend to the latter. Finally, there is Fossil, which starts from the other end by attempting to replace git entirely and tracking itself. I am however not too comfortable with the thought of replacing git, and Fossil's non-SCM features don't seem to be as developed. Now before I invest too much time when someone else might already have tried this, I basically have two questions: Are there crucial features of Project Management software like Redmine that Foswiki does not provide even with all the extensions available? How to set Foswiki up to use git instead of the perl RcsLite?

• Choosing the right language for the job

  - by Ampt

  I'm currently working for a company on the engineering team of about 5-6 people and have been given the job of heading up the redesign of an embedded system tester. We've decided the general requirements and attributes that would be desirable in the system, and now I have to decide on a language to use for the system, or at the very least come up with a list of languages with pros and cons to present to the team. The general idea of the project is that we currently have a tester written in c++, which was never designed to be a tester, but instead has evolved to be such over the course of 3-4 years due to need. Writing tests for a new product requires modifying the 'framework' and writing code that is completely non-human readable or intuitive due to the way the system was originally designed. Now, we've decided that the time to modify this tester for each new product that we want to test has become too high and want to partially re-write the system so that we can program the actual tests in a scripting language that would then use the modified c++ framework on the back end to test the actual systems. The c++ framework would be responsible for doing all the actual work and the scripting language would just integrate with that to tell the framework what to do. Never having programmed in a scripting language (we program embedded systems), I've run into a wall where I have no experience with any of the languages that we could possibly use, but must somehow give pros and cons of each language so that we can choose the best one for the job. Currently my short list of possibilities includes: Python TCL Lua Perl My question is this: How can a person evaluate a language that he/she has never used before? What criteria are good indicators for a languages potential usability on a project? While helpful suggestions for my particular case are appreciated, I feel that this is a good skill to possess and would like to be able to apply this to many different projects if at all possible

• Is it wise to ask about design decisions made on a product during an interview?

  - by Desolate Planet

  I've been thinking about interview questions lately and I've been reflecting on bad interview experiences I've had in the past. One of particular note is where I had asked the interviewer why the team chose to use Spring over EJB3 in their product. The interviewer pretty much tore my face off, yelling "Because Spring is not the be all and end all of Java software development, do you want this job or not?". In response to this, I told him that this probably wasn't the job for me and I walked out the interview. He told me at the start of the interview that they had high stuff turnover, the product had gone from Modula 3 to Perl to Java then after asking him a technical question, he went in flames. It seemed obvious to me that he was toxic to the company with that kind of attitude. Question: Is it a good idea to probe on architectural choices taken in an interview? If not, why? From my own point of view, an interview is a two-way process. If the interviewers are testing me on my technical skills, I've got every right to ask them the same questions to 1) Figure out what their mindset and attitudes towards developing software solutions are and 2) To figure out if there are in line with how I would approach problems of that kind. It's very possible that the interviewer who got angry was a bad interviewer and forgot that an interview is a two-way process. If I was asked this, I would have simply said something along the lines of wanting to leverage the container more, but I certainly wouldn't have tried to put him in a state of meek capitulation. The interviewer in question was the lead developer in the team.

• Software for video subscription service

  - by Clinton Blackmore

  I'd like to sell instructional videos over the web. Primarily, I'd like uses to subscribe to the site and be allowed access to videos over the internet. Secondarily, I might sell DVDs for those who have poor internet connections or would like a physical copy, or possibly I'd sell eBooks and the like in the future. Regarding the subscriptions: I'd like a system that automatically sends out e-mails when it is time to renew I'd like to be able to offer free trials Users without a free trial or subscription should not be able to access the content Incidentally, I plan to host videos on my current web host and move them to a CDN when volume (and capital) make this a good idea. While I have no intention to go crazy with the DRM, it seems expedient not to directly link to the files -- how can I link to them indirectly? It would be nice to support multiple payment processors -- specifically, I'd like to avoid a PayPal only approach. Are there any web applications (or plugins) you'd recommend for something like this? While I've set up and administered several web technologies, I've never done anything with e-commerce. I see there are possibilities like osCommerce, one friend recommends using WordPress with plugins, and it really appears that for any given CMS, you can graft on components like this, although I imagine that not all are created equal. As I'm not tied to a particular web application (and, while open source software that can run on a LAMP [p=perl, python, php] stack is preferable), I'd like to make a good choice at the beginning.

• rkhunter: right way to handle warnings further?

  - by zuba

  I googled some and checked out two first links it found: http://www.skullbox.net/rkhunter.php http://www.techerator.com/2011/07/how-to-detect-rootkits-in-linux-with-rkhunter/ They don't mention what shall I do in case of such warnings: Warning: The command '/bin/which' has been replaced by a script: /bin/which: POSIX shell script text executable Warning: The command '/usr/sbin/adduser' has been replaced by a script: /usr/sbin/adduser: a /usr/bin/perl script text executable Warning: The command '/usr/bin/ldd' has been replaced by a script: /usr/bin/ldd: Bourne-Again shell script text executable Warning: The file properties have changed: File: /usr/bin/lynx Current hash: 95e81c36428c9d955e8915a7b551b1ffed2c3f28 Stored hash : a46af7e4154a96d926a0f32790181eabf02c60a4 Q1: Is there more extended HowTos which explain how to deal with different kind warnings? And the second question. Were my actions sufficient to resolve these warnings? a) To find the package which contains the suspicious file, e.g. it is debianutils for the file /bin/which ~ > dpkg -S /bin/which debianutils: /bin/which b) To check the debianutils package checksums: ~ > debsums debianutils /bin/run-parts OK /bin/tempfile OK /bin/which OK /sbin/installkernel OK /usr/bin/savelog OK /usr/sbin/add-shell OK /usr/sbin/remove-shell OK /usr/share/man/man1/which.1.gz OK /usr/share/man/man1/tempfile.1.gz OK /usr/share/man/man8/savelog.8.gz OK /usr/share/man/man8/add-shell.8.gz OK /usr/share/man/man8/remove-shell.8.gz OK /usr/share/man/man8/run-parts.8.gz OK /usr/share/man/man8/installkernel.8.gz OK /usr/share/man/fr/man1/which.1.gz OK /usr/share/man/fr/man1/tempfile.1.gz OK /usr/share/man/fr/man8/remove-shell.8.gz OK /usr/share/man/fr/man8/run-parts.8.gz OK /usr/share/man/fr/man8/savelog.8.gz OK /usr/share/man/fr/man8/add-shell.8.gz OK /usr/share/man/fr/man8/installkernel.8.gz OK /usr/share/doc/debianutils/copyright OK /usr/share/doc/debianutils/changelog.gz OK /usr/share/doc/debianutils/README.shells.gz OK /usr/share/debianutils/shells OK c) To relax about /bin/which as I see OK /bin/which OK d) To put the file /bin/which to /etc/rkhunter.conf as SCRIPTWHITELIST="/bin/which" e) For warnings as for the file /usr/bin/lynx I update checksum with rkhunter --propupd /usr/bin/lynx.cur Q2: Do I resolve such warnings right way?

• Unit Tests as a learning tool - a good idea?

  - by Ekkehard.Horner

  I'm interested in ways and means for learning (a) programming language(s) efficiently. I believe that using Unit Test concepts and infrastructure early in that process is a good thing, even better than starting with "Hello world". Why: To write a decent program even for a toy/restricted problem in a new language, you'll have to master many heterogenous concepts (control flow & variables & IO ...), you are tempted to glance over details just to get your program 'to work'. Putting (your understanding of) the facts about the new language in assertions with good descriptions (=success messages) enforces thinking thru/clearness/precision. Grouping topics and adding assertions to such groups is much easier than incorporation features from the 2. chapter of your "Learning X" book to your chapter 1 program. Why not: 'Real' Unit Tests are meant to output "1234 tests ok; 1 failure: saveWorld() chokes on negative input"; 'didactic' Unit Tests should output relevant facts about the new language like perl6 10-string.t # ### p5chop ... ok 13 - p5chop( "cbä" ) returns "ä" ok 14 - after that, victim is changed to "cb" # ### (p6) chop ... ok 27 - (p6) chop( "cbä" ) returns chopped copy: "cb" ok 18 - after that, victim is unchanged: "cbä" # ### chomp ... So (mis?)using Unit Tests may be counterproductive - practicing actions while learning you wouldn't use professionally. How: Writing 'didactic' Unit Tests in languages with lightweight testing systems (Perl 5/6) is easy; (mis?)using more elaborate systems (JUnit, CppUnit) may be not worth the effort or not suitable for a person just starting with a new language. So Is using Unit Tests as a learning tool a bad idea? Can the Unit Test tool(s) of your favourite language(s) used didactically? Should implementation details (eventually) be discussed here or over at stackoverflow.com?

• Is Movable Type among the most secure PHP blogs? How secure are the various PHP blog applications?

  - by user6025

  Basically I'm trying to find a blog for a website, and security is the highest priority in our case. We don't need any features that I would imagine are special. Wordpress was our first idea, but its reputation precedes it, and though it may have cleaned up its act lately, I'm not seeing much solid evidence. I get the impression that Movable Type (at least the Perl version) has a much better reputation for security than Wordpress (historically at least). I'm not sure I want to take a chance with Wordpress at this point, but is there some objective source I can got to to back up (or counter) the notion that MT is at least among the best? Secunia doesn't recommend using their stats for comparisons, and securityfocus.com doesn't have stats at all that I can see. Searching here http://web.nvd.nist.gov makes MT look way better than WP (at least in 2007), but this site was referenced by MT's own page boasting about their security, so I don't know how relevant it is or how seriously people take it. Any suggestions on sites where I could/should make a somewhat objective comparison?

• Formatting php, what works more efficiently?

  - by JamesM-SiteGen

  Hello fellow programmers, I was just wondering what makes php work faster, I have a few methods that I always go and do, but that only improves the way I can read it, but how about the interpreter? Should I include the curly braces when there is only one statement to run? if(...){ echo "test"; } # Or.. if(...) echo "test"; === Which should be used? I have also found http://beta.phpformatter.com/ and I find the following settings to be good, but are they? Indentation: Indentation style: {K&R (One true brace style)} Indent with: {Tabs} Starting indentation: [1] Indentation: [1] Common: [x] Remove all comments [x] Remove empty lines [x] Align assignments statements nicely [ ] Put a comment with the condition after if, while, for, foreach, declare and catch statements Improvement: [x] Remove lines with just a semicolon (;) [x] Make normal comments (//) from perl comments (#) [x] Make long opening tag (<?php) from short one (<?) Brackets: [x] Space inside brackets- ( ) [x] Space inside empty brackets- ( ) [x] Space inside block brackets- [ ] [x] Space inside empty block brackets- [ ] Tiny var names: often I go through my code and change $var1 to $a, $var2 to $b and so on. I do include comments at the start of the file to show to me what each letter(s) mean.. Final note: So am I doing the right thing with the curly braces and the settings? Are there any great tips that help it run faster?

• What does your Lisp workflow look like?

  - by Duncan Bayne

  I'm learning Lisp at the moment, coming from a language progression that is Locomotive BASIC - Z80 Assembler - Pascal - C - Perl - C# - Ruby. My approach is to simultaneously: write a simple web-scraper using SBCL, QuickLisp, closure-html, and drakma watch the SICP lectures I think this is working well; I'm developing good 'Lisp goggles', in that I can now read Lisp reasonably easily. I'm also getting a feel for how the Lisp ecosystem works, e.g. Quicklisp for dependencies. What I'm really missing, though, is a sense of how a seasoned Lisper actually works. When I'm coding for .NET, I have Visual Studio set up with ReSharper and VisualSVN. I write tests, I implement, I refactor, I commit. Then when I'm done enough of that to complete a story, I write some AUATs. Then I kick off a Release build on TeamCity to push the new functionality out to the customer for testing & hopefully approval. If it's an app that needs an installer, I use either WiX or InnoSetup, obviously building the installer through the CI system. So, my question is: as an experienced Lisper, what does your workflow look like? Do you work mostly in the REPL, or in the editor? How do you do unit tests? Continuous integration? Packaging & deployment? When you sit down at your desk, steaming mug of coffee to one side and a framed photo of John McCarthy to the other, what is it that you do? Currently, I feel like I am getting to grips with Lisp coding, but not Lisp development ...

• Netcat I/O enhancements

  - by user13277689

  When Netcat integrated into OpenSolaris it was already clear that there will be couple of enhancements needed. The biggest set of the changes made after Solaris 11 Express was released brings various I/O enhancements to netcat shipped with Solaris 11. Also, since Solaris 11, the netcat package is installed by default in all distribution forms (live CD, text install, ...). Now, let's take a look at the new functionality: /usr/bin/netcat alternative program name (symlink) -b bufsize I/O buffer size -E use exclusive bind for the listening socket -e program program to execute -F no network close upon EOF on stdin -i timeout extension of timeout specification -L timeout linger on close timeout -l -p port addr previously not allowed usage -m byte_count Quit after receiving byte_count bytes -N file pattern for UDP scanning -I bufsize size of input socket buffer -O bufsize size of output socket buffer -R redir_spec port redirection addr/port[/{tcp,udp}] syntax of redir_spec -Z bypass zone boundaries -q timeout timeout after EOF on stdin Obviously, the Swiss army knife of networking tools just got a bit thicker. While by themselves the options are pretty self explanatory, their combination together with other options, context of use or boundary values of option arguments make it possible to construct small but powerful tools. For example: the port redirector allows to convert TCP stream to UDP datagrams. the buffer size specification makes it possible to send one byte TCP segments or to produce IP fragments easily. the socket linger option can be used to produce TCP RST segments by setting the timeout to 0 execute option makes it possible to simulate TCP/UDP servers or clients with shell/python/Perl/whatever script etc. If you find some other helpful ways use please share via comments. Manual page nc(1) contains more details, along with examples on how to use some of these new options.
