  • CentOS server. What does it mean when the total used RAM does not equal the sum of RES?

    - by Michael Green
    I'm having a problem with a virtual hosted server running CentOS. In the past month a process (java based) that had been running fine started having problems getting memory when the JVM was started. One strange thing I've noticed is that when I start the process, the PID says it is using 470mb of RAM while the 'used' memory immediately drops by over a 1GB. If I run 'top', the total RES used across all processes falls short of the 'used' listed at the top by almost 700mb. The support person says this means I have a memory leak with my process. I don't know what to believe because I would expect a memory leak to simply waste the memory the process is allocated not to consume additional memory that doesn't show up using 'top'. I'm a developer and not a server guy so I'm appealing to the experts. To me, if the total RES memory doesn't add up to the total 'used' it indicates that something is wrong with my virtual server set-up. Would you also suspect a memory leaking java process in this case? If I use free before: total used free shared buffers cached Mem: 2097152 149264 1947888 0 0 0 -/+ buffers/cache: 149264 1947888 Swap: 0 0 0 free after: total used free shared buffers cached Mem: 2097152 1094116 1003036 0 0 0 -/+ buffers/cache: 1094116 1003036 Swap: 0 0 0 So it looks as though the process is using (or causing to be used) nearly 1GB of RAM. Since the process (based on top is only using 452mb, does that mean that the kernal is all of a sudden using an additional 500mb?

  • How do I create English-language list (name1, name2, AND name3) in Ruby on Rails?

    - by Angela
    Quite possibly there could be a rails magic I've missed, but I'm guessing it will be in Ruby. I have a model called Company which has_many Contacts. Suppose Company has Contact 1, Contact 2, Contact 3, and Contact 4. When I create a textblog for each Contact, I want to output the following (where Contact = Contact 1) "Hi, Contact 1, I am also writing to Contact 2, Contact 3, and Contact 4." So it needs to extract the Contact in the salutation and then list them, inserting "and" before the last Contact in the list.

  • Why doesn't every, and I mean it, language have this feature?

    - by dada
    Some time ago I had a look into Ruby and one of the things which stood out most for me was the way of using symbols. While you to use defines or strings like in C++ or Python as an alternative, in Ruby you just write :mySymbol and the interpreter takes over the enumeration for you. I can't see any disadvantage this feature has, so why is it missing in say, PHP and Python?

  • Which work process in my company should I Improve first?

    - by shoren
    I've just started to work in a new place, and I see several things they do that I find really terrible, and I want to know if they are indeed so wrong, or I am just too strict. Please let me know if my criticism is in place, and your opinion on which problem is the worst and should be fixed first. The developement is all in Java. 1) Not using svnignore. This means svn stat can't be used, and developers forget to add files and break the build. 2) Generated files go to same folders as committed files. Can't use simple maven clean, have to find them one by one. Maven clean doesn't remove all of them. 3) Not fixing IDE analyze warnings. Analyze code returns about 5,000 warning, of many different kinds. 4) Not following conventions: spring beans names sometimes start with uppercase and sometimes not, ant properties sometimes with underline and sometimes with dots delimiter, etc. 5) Incremental build takes 6 minutes, even when nothing is changed. 6) Developers only use remote debug, and don't know how to run the Tomcat server internally from the IDE. 7) Developers always restart the server after every compilation, instead of dynamically reloading the class and saving the server's state. It takes them at least 10 minutes to start checking any change in the code. 8) Developers only compile from command line. When there are compilation errors, they manually open the file and go the the problematic line. 9) A complete mess in project dependencies. Over 200 open sources are depended on, and no one knows what is indeed needed and why. They do know that not all dependencies are necessary. 10) Mixing Maven and Ant in a way that disables the benefits of both. In one case, even dependency checks are not done by Maven. 11) Not using generics properly. 12) Developers don't use Subversion integration with IDE (Eclipse, Intellij Idea). What do you think? Where should I start? Is any of the things I mentioned not really a problem?

  • Which relational databases exist with a public API for a high level language?

    - by Jens Schauder
    We typically interface with a RDBMS through SQL. I.e. we create a sql string and send it to the server through JDBC or ODBC or something similar. Are there any RDBMS that allow direct interfacing with the database engine through some API in Java, C#, C or similar? I would expect an API that allows constructs like this (in some arbitrary pseudo code): Iterator iter = engine.getIndex("myIndex").getReferencesForValue("23"); for (Reference ref: iter){ Row row = engine.getTable("mytable").getRow(ref); } I guess something like this is hidden somewhere in (and available from) open source databases, but I am looking for something that is officially supported as a public API, so one finds at least a note in the release notes, when it changes. In order to make this a question that actually has a 'best' answer: I prefer languages in the order given above and I will prefer mature APIs over prototypes and research work, although these are welcome as well.

  • How do I write a bash script to restart a process if it dies?

    - by Tom
    I have a python script that'll be checking a queue and performing an action on each item: # checkqueue.py while True: check_queue() do_something() How do I write a bash script that will check if it's running, and if not, start it. Roughly the following pseudo code (or maybe it should do something like ps | grep?): # keepalivescript.sh if processidfile exists: if processid is running: exit, all ok run checkqueue.py write processid to processidfile I'll call that from a crontab: # crontab */5 * * * * /path/to/keepalivescript.sh Thanks in advance.

  • How can I get the "Latency" of a process that has a TCP connection open?

    - by Dave
    Hello, I am looking to get the "Latency" field of a TCP connection. I notice windows Resource Monitor has this field, and I was wondering if there was a way I can find it. Preferrably without using WMI. If you are unsure what field I am talking about, open Task Manager, goto the Performance tab and hit the Resource Monitor button. Once Resource Monitor is open, expand the TCP Connections area and you will see a Latency field. Is there anyway to access this programatically? Thanks!

  • Address of array vs. address of array[0] - C language

    - by user324994
    My question is why does the address of an array differ from the address of its first position? I'm trying to write my own malloc, but to start out I'm just allocating a chunk of memory and playing around with the addresses. My code looks roughly like this: #define BUFF_SIZE 1024 static char *mallocbuff; int main(){ mallocbuff = malloc(BUFF_SIZE); printf("The address of mallocbuff is %d\n", &mallocbuff); printf("The address of mallocbuff[0] is %d\n", &mallocbuff[0]); } &mallocbuff is the same address every time I run it. &mallocbuff[0] is some random address every time. I was expecting the addresses to match each other. Can anyone explain why this isn't the case?

  • which language to choose for a LIVE web application?

    - by fayer
    i want to create not only a web application, but a web application where everything is LIVE. eg. if someone posts a message and then another one replies, then the creator will get on his webpage a notification. and also i want to implement a chat in the web application. i want these features to be implemented using true server-push (no javascript polling)! because i only want to create web applications i don't think i will use java. i wonder if i should use python, ruby or php for this? thanks

  • What next generation low level language is the best bet to migrate the code base ?

    - by e-satis
    Let's say you have a company running a lot of C/C++, and you want to start planning migration to new technologies so you don't end up like COBOL companies 15 years ago. For now, C/C++ runs more than fine and there is plenty dev on the market for it. But you want to start thinking about it now, because given the huge running code base and the data sensitivity, you feel it can take 5-10 years to move to the next step without overloading the budget and the dev teams. You have heard about D, starting to be quite mature, and Go, promising to be quite popular. What would be your choice and why?

  • Does any language have a while-else flow structure?

    - by dotancohen
    Consider this flow structure which I happen to use often: if ( hasPosts() ) { while ( hasPosts() ) { displayNextPost(); } } else { displayNoPostsContent(); } Are there any programming languages which have an optional else clause for while, which is to be run if the while loop is never entered? Thus, the code above would become: while ( hasPosts() ) { displayNextPost(); } else { displayNoPostsContent(); } I find it interesting that many languages have the do-while construct (run the while code once before checking the condition) yet I have never seen while-else addressed. There is precedent for running an N block of code based on what was run in N-1 block, such as the try-catch construct. I wasn't sure whether to post here or on programmers.SE. If this question is more appropriate there, then please move it. Thanks.

  • Security concerns for a multi-lingual web application.

    - by The Rook
    I am converting a PHP MySQL web application written for English language into a Multi-Language site. Do you know any vulnerabilities that affect web applications in another language? Or perhaps vulnerabilities that could be introduced in the conversion of code base to support multiple languages. (If you know any vulnerabilities of this type in another programming language I'll give you a +1)

  • Sys. engineer has decided to dynamically transform all XSLs into DLLs on website build process. DLL

    - by John Sullivan
    Hello, OS: Win XP. Here is my situation. I have a browser based application. It is "wrapped" in a Visual Basic application. Our "Systems Engineer Senior" has decided to spawn DLL files from all of our XSL pages (many of which have duplicate names) upon building a new instance of the website and have the active server pages (ASPX) use the DLL instead. This has created a "known issue" in which ~200 DLL naming conflicts occur and, thus, half of our application is broken. I think a solution to this problem is that, thankfully, we're generating the names of the DLLs and linking them up with our application dynamically. Therefore we can do something kludgy like generate a hash and append it to the end of the DLL file name when we build our website, then always reference the DLL that had some kind of random string / hash appended to its name. Aside from outright renaming the DLLs, is there another way to have multiple DLLs with the same name register for one application? I think the answer is "No, only between different applications using a special technique." Please confirm. Another question I have on my mind is whether this whole idea is a good practice -- converting our XSL pages (which we use in mass -- every time a response from our web app occurs) into DLL functions that call a "function" to do what the XSL page did via an active server page (ASPX), when we were before just sending an XML response to an XSL page via aspx.

  • Is False == 0 and True == 1 in Python an implementation detail or guaranteed by the language?

    - by EOL
    Is it guaranteed that False == 0 and True == 1, in Python? For instance, is it in any way guaranteed that the following code will always produce the same results, whatever the version of Python (existing and in the foreseeable future)? 0 == False # True 1 == True # True ['zero', 'one'][False] # is 'zero' Any reference to the official documentation would be much appreciated! Other comments would be appreciated too… :) Edit: As noted in many answers, bool inherits from int. The question can therefore be recast as: "Is this an implementation detail that might change in the future, or does the documentation officially say that programmers can rely on booleans inheriting from integers?". This question is relevant for writing robust code that won't fail because of implementation details! Edit 2: The original question is still open, I believe (even though I accepted what I thought was the closest answer): even though Python 3 officially recognizes booleans as integers, I have not yet seen any official integer values for False and True… It therefore looks to me like it is best to stay clear from the assumption that False==0 and True==1.

  • Possible to distribute or parallel process a sequential program?

    - by damigu
    In C++, I've written a mathematical program (for diffusion limited aggregation) where each new point calculated is dependent on all of the preceding points. Is it possible to have such a program work in a parallel or distributed manner to increase computing speed? If so, what type of modifications to the code would I need to look into?

  • What programming language do you wear a suit for?

    - by Paul
    My company writes mostly .NET code, I work in a professional, 'business casual' environment. Both of these things seemed pretty ubiquitous across the corporate software world, however I recently visited a few companies that use PHP/Ruby and nearly all their devs had facial piercings/visible tattoos, etc. and their offices had no apparent dress code. This might sound funny, but it made me wonder, is there any correlation between specific technology and office culture? For example, have you ever had to wear a suit to a programming job, and if so what technology did you use?

  • At what point in the render process of a web page can we interact with that page

    - by Bamerza
    I'd like to measure to distinct user experience points during the rendering of an HTML page: 1) Point which user sees the first painting of the page 2) Point at which user can interact with the page - meaning sees 75% of it or can actually register a button click or link click I am pretty certain these UX interactions can start before the HTML code is fully rendered, so would that instance be the JS func "OnLoad" or some other distinct measureable value/function? If it helps, we can even narrow the answer down to webkit based browsers.

  • SCons and dependencies for python function generating source

    - by elmo
    I have an input file data, a python function parse and a template. What I am trying to do is use parse function to get dictionary out of data and use that to replace fields in template. Now to make this a bit more generic (I perform the same action in few places) I have defined a custom function to do so. Below is definition of custom builder and values is a dictionary with { 'name': (data_file, parse_function) } (you don't really need to read through this, I simply put it here for completeness). def TOOL_ADD_FILL_TEMPLATE(env): def FillTemplate(env, output, template, values): out = output[0] subs = {} for name, (node, process) in values.iteritems(): def Process(env, target, source): with open( env.GetBuildPath(target[0]), 'w') as out: out.write( process( source[0] ) ) builder = env.Builder( action = Process ) subs[name] = builder( env, env.GetBuildPath(output[0])+'_'+name+'_processed.cpp', node )[0] def Fill(env, target, source): values = dict( (name, n.get_contents()) for name, n in subs.iteritems() ) contents = template[0].get_contents().format( **values ) open( env.GetBuildPath(target[0]), 'w').write( contents ) builder = env.Builder( action = Fill ) builder( env, output[0], template + subs.values() ) return output env.Append(BUILDERS = {'FillTemplate': FillTemplate}) It works fine when it comes to checking if data or template changed. If it did it rebuilds the output. It even works if I edit process function directly. However if my process function looks like this: def process( node ): return subprocess(node) and I edit subprocess the change goes unnoticed. Is there any way to get correct builds without making process functions being always invoked?
