  • Artificial Inteligence library in python

    - by João Portela
    I was wondering if there are any python AI libraries similar to aima-python but for a more recent version of python... and how they are in comparison to aima-python. I was particularly interested in search algorithms such as hill-climbing, simulated annealing, tabu search and genetic algorithms. edit: made the question more clear.

  • domain specific languages and compilers

    - by hyperboreean
    I was looking over Martin Fowler's recent book contents - Domain Specific Languages and I noticed some ANTLR example - that got me thinking that writing compilers will become more and more popular since people needs in this matter will increase. So, will the compiler theory still be as arid (being subjective here) as it was until now or are there any chances that we'll get more applied, programmer oriented materials ?

  • VSLauncher starts wrong version

    - by Matthew Scouten
    I have 3 versions of Visual Studio installed, and 3 projects that require a specific version. VSLauncher USED to look at the SLN or VCPROJ file and open the correct version of Visual Studio. Now it only starts the most recent version, regardless of the project. Note that this has nothing to do with the commonly reported problem with beta versions of VS. none of the SLNs have ever been touched by a beta VS.

  • Git sh.exe process forking issue on windows XP, slow?

    - by AndyL
    Git is essential to my workflow. I run MSYS Git on Windows XP on my quad core machine with 3GB of RAM, and normally it is responsive and zippy. Suddenly an issue has cropped up whereby it takes 30 seconds to run any command from the Git Bash command prompt, including ls or cd. Interestingly, from the bash prompt it looks likes ls runs fairly quickly, I can then see the output from ls, but it then takes ~30 seconds for the prompt to return. If I switch to the windows command prompt (by running cmd from the start menu) git related commands also take forever, even just to run. For example git status can take close to a minute before anything happens. Sometimes the processes simply don't finish. Note that I have "MSYS Git" installed as well as regular "MSYS" for things like MinGW and make. I believe the problem is related to sh.exe located in C:\Program Files\Git\bin. When I run ls from the bash prompt, or when I invoke git from the windows prompt, task manager shows up to four instances of sh.exe processes that come and go. Here I am waiting for ls to return and you can see the task manager has git.exe running and four instances of sh.exe: If I ctrl-c in the middle of an ls I sometimes get errors that include: sh.exe": fork: Resource temporarily unavailable 0 [main] sh.exe" 1624 proc_subproc: Couldn't duplicate my handle<0x6FC> fo r pid 6052, Win32 error 5 sh.exe": fork: Resource temporarily unavailable Or for git status: $ git status sh.exe": fork: Resource temporarily unavailable sh.exe": fork: Resource temporarily unavailable sh.exe": fork: Resource temporarily unavailable sh.exe": fork: Resource temporarily unavailable Can I fix this so that git runs quickly again, and if so how? Things I have tried: Reboot Upgrade MSYS Git to most recent version & Reboot Upgrade MSYS to most recent version & Reboot Uninstall MSYS & uninstall and reinstall MSYS Git alone & Reboot I'd very much like to not wipe my box and reinstall Windows, but I will if I can't get this fixed. I can no longer code if it takes me 30 s to run git status or cd.

  • Is there a Pac-Man-like character in ASCII or Unicode?

    - by Ricket
    Simple question: is there a character that looks either like Pac-Man, or like the ghost in Pac-Man? With Google's recent Pac-Man logo, everyone should know what these look like, but in case you don't here are some sample images: If you answer "no" please provide a little more proof that you actually searched all unicode characters...

  • Are there some newer books to read beside these?

    - by Gandalf StormCrow
    I've come accross these websites who recommend certain books but they are pretty much old : http://www.joelonsoftware.com/navLinks/fog0000000262.html http://www.codinghorror.com/blog/2004/02/recommended-reading-for-developers.html http://sites.google.com/site/steveyegge2/ten-great-books Are there books in recent years which every developer should read?I'm mostly interested about Java/Spring/Hibernate/Jboss although reading book about programming in general wouldn't be bad.

  • PHP 6.0 - Roadmap?

    - by JustinT
    With the recent announcement that PHP 6 development has been halted, I'm confused as to what the PHP 5.x and 6.x road map includes. The current version of PHP is 5.3.2. There were quite a few significant features to come in PHP 6.0, such as: APC include for automatic bytecode caching Unicode support etc.. Question: What is the new road map of PHP given 6.0 has been canceled? What major features will be available next and in what release?

  • c# linq to xml dynamic query

    - by David Archer
    Right, bit of a strange question; I have been doing some linq to XML work recently (see my other recent posts here and here). Basically, I want to be able to create a query that checks whether a textbox is null before it's value is included in the query, like so: XDocument db = XDocument.Load(xmlPath); var query = (from vals in db.Descendants("Customer") where (if(textbox1.Text != "") {vals.Element("CustomerID") == Convert.ToInt32(textbox1.Text) } || if(textbox2.Text != "") {vals.Element("Name") == textbox2.Text}) select vals).ToList();

  • understanding semcor corpus structure h

    - by Sharmila
    I'm learning NLP. I currently playing with Word Sense Disambiguation. I'm planning to use the semcor corpus as training data but I have trouble understanding the xml structure. I tried googling but did not get any resource describing the content structure of semcor. <s snum="1"> <wf cmd="ignore" pos="DT">The</wf> <wf cmd="done" lemma="group" lexsn="1:03:00::" pn="group" pos="NNP" rdf="group" wnsn="1">Fulton_County_Grand_Jury</wf> <wf cmd="done" lemma="say" lexsn="2:32:00::" pos="VB" wnsn="1">said</wf> <wf cmd="done" lemma="friday" lexsn="1:28:00::" pos="NN" wnsn="1">Friday</wf> <wf cmd="ignore" pos="DT">an</wf> <wf cmd="done" lemma="investigation" lexsn="1:09:00::" pos="NN" wnsn="1">investigation</wf> <wf cmd="ignore" pos="IN">of</wf> <wf cmd="done" lemma="atlanta" lexsn="1:15:00::" pos="NN" wnsn="1">Atlanta</wf> <wf cmd="ignore" pos="POS">'s</wf> <wf cmd="done" lemma="recent" lexsn="5:00:00:past:00" pos="JJ" wnsn="2">recent</wf> <wf cmd="done" lemma="primary_election" lexsn="1:04:00::" pos="NN" wnsn="1">primary_election</wf> <wf cmd="done" lemma="produce" lexsn="2:39:01::" pos="VB" wnsn="4">produced</wf> <punc>``</punc> <wf cmd="ignore" pos="DT">no</wf> <wf cmd="done" lemma="evidence" lexsn="1:09:00::" pos="NN" wnsn="1">evidence</wf> <punc>''</punc> <wf cmd="ignore" pos="IN">that</wf> <wf cmd="ignore" pos="DT">any</wf> <wf cmd="done" lemma="irregularity" lexsn="1:04:00::" pos="NN" wnsn="1">irregularities</wf> <wf cmd="done" lemma="take_place" lexsn="2:30:00::" pos="VB" wnsn="1">took_place</wf> <punc>.</punc> </s> I'm assuming wnsn is 'word sense'. Is it correct? What does the attribute lexsn mean? How does it map to wordnet? What does the attribute pn refer to? (third line) How is the rdf attribute assigned? (again third line) In general, what are the possible attributes?

  • In Jetty, can NCSARequestLog be configured to auto-detect the time zone?

    - by David Moles
    It looks as though in 2003 or so NCSARequestLog would pick up the system time zone using TimeZone.getDefault().getID(), but in more recent versions it seems as though it's hard-coded to GMT, unless you override it in jetty.xml or programmatically. If true, this kind of annoying, since it means if you don't want GMT logging you have to edit jetty.xml for every installation (not to mention twice a year for daylight saving time). Is there a workaround that will let Jetty pick the time zone up from the system?

  • iPhone or Android?

  • When is it safe to remote import entires from feature.xml?

    - by Robert Munteanu
    I've recently learned that the import section from feature.xml is legacy, and the actual dependency work is delegated to the p2 engine, which uses the information from the plugin manifest. I am not sure though if p2 is available for all recent versions of Eclipse, or in all Eclipse-based products, so I'm not sure if it is safe to remove the import section from feature.xml. Under what circumstances is it safe to remove the import section from feature.xml? Assume that we are taking into consideration Eclipse 3.4 or newer.

  • Why there is no open source framework (like Java) for C# application development?

    - by Calvin
    Hi, C# is much more popular than Java in recent years. As a general-purpose programming language, many people feel that C# is better designed than Java. Why until now there is no open source framework for C# application development? Why no one take the initiative to develop a open source framework for C# which is comparable to Java? (Many people say Mono is not a mature framework and should not be used in serious application development.) Calvin
