  • javamail vs sendmail performance during bulk email

    - by Glenn2041
    Hi all, I'm writing a Java mass emailer application to send out emails to send between 50,000 to 100,000 a day to users. The current plan is to delegate the sending to delegate to sendmail (on the local unix server). From our testing sendmail is sending a maximum of 5 emails per second. Would JavaMail be a faster option? Does anyone know what a faster way to send emails. We want to get this process out as quick as possible. Edit: BTW, a pdf will be attached too

  • Printing Stdout In Command Line App Without Overwriting Pending User Input

    - by Chris S
    In a basic Unix-shell app, how would you print to stdout without disturbing any pending user input. e.g. Below is a simple Python app that echos user input. A thread running in the background prints a counter every 1 second. import threading, time class MyThread( threading.Thread ): running = False def run(self): self.running = True i = 0 while self.running: i += 1 time.sleep(1) print i t = MyThread() t.daemon = True t.start() try: while 1: inp = raw_input('command> ') print inp finally: t.running = False Note how the thread mangles the displayed user input as they type it (e.g. hell1o wo2rld3). How would you work around that, so that the shell writes a new line while preserving the line the user's currently typing on?

  • Jdeveloper vs java/j2ee/js+extjs ?

    - by ssgam
    Hi All, i am new to the web development environment, having came from a unix/c environment. i've been recently asked to create a web app, which i thought would require postgresql, java/j2ee, and javascript for the client interface. as i had wanted a nicer gui, i've been reading up on extjs, which looks really nice to me. a colleague mentioned that the time needed time needed to learn all these various pieces is time consuming, and Jdeveloper seems to provide most of what we'd need (i was shown a demo, which appears to be able to generate some nice web interfaces). what are the pros and cons with the different approaches ? some i can think of: - jdeveloper is an integrated ide, which creates UI easily, tightly integrated with database. (pro) - jdeveloper will be heavier? (con) - wizard generated code may be harder to refactor ? (con) - java/j2ee/js+extjs needs to develop things from ground up (con) thanks in advance for sharing your experiences and thoughts ... sam

  • GCC without Xcode on OS X

    - by Konrad Rudolph
    I've just unwrapped my new MacBook Pro (yay!) and am now setting it up properly for development. Since I want to avoid clutter, I'm wondering if I really need to install the Xcode tools at all (I never use the IDE or Mac specific tools), since I'll install a newer version of GCC anyway, using MacPorts. So, is there any benefit in installing Xcode? Is it necessary? What kind of set-up does it do behind the scenes? Basically: can I skip this or will it come back to haunt me because some Unix development tools just assume that OS X is always set up in this way?

  • C Privilege Escalation (With Password)

    - by AriX
    Hey everyone, I need to write a C program that will allow me to read/write files that are owned by root. However, I can only run the code under another user. I have the root password, but there are no "sudo" or "su" commands on the system, so I have no way of accessing the root account (there are practically no shell commands whatsoever, actually). I don't know a whole lot about UNIX permissions, so I don't know whether or not it is actually possible to do this without exploiting the system in some way or running a program owned by root itself (with +s or whatever). Any advice? Thanks! P.S. No, this isn't anything malicious, this is on an iPhone.

  • teaching my self Z/OS assembler?

    - by Jared
    'I've interned at a company that does a lot of mainframe work. Most of my mainframe experience has been using Java and Unix System Services. I've had some experience with the ISPF interface and C but none with assembler. I’m graduating shortly and will be taking an independent study my last semester. I’d like to stick with the mainframe and was wondering what resources could teach me mainframe assembler? Note I don’t have experience writing assembler for any platform but do understand binary, hex, and have a theoretical understanding of registers.

  • Javascript DateFormat for different timezones

    - by Elie
    I'm a Java developer and I'm used to the SimpleDateFormat class that allows me to format any date to any format by settings a timezone. Date date = new Date(); SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy hh:mm:ss"); sdf.setTimeZone(TimeZone.getTimeZone("America/Los_Angeles")); System.out.println(sdf.format(date)); // Prints date in Los Angeles sdf.setTimeZone(TimeZone.getTimeZone("America/Chicago")); System.out.println(sdf.format(date)); // Prints same date in Chicago SimpleDateFormat is a pretty neat solution in Java but unfortunately I can't find any similar alternative in Javascript. I'm extending the Date prototype in Javascript to do exactly the same. I have dates in Unix format but I want to format them in different timezones. Date.prototype.format = function(format, timezone) { // Now what? return formattedDate; } I'm looking for a neat way to do this rather than a hack. Thanks

  • Bourne Script: Redirect success messages but NOT error messages

    - by sixtyfootersdude
    This command: keytool -import -file "$serverPath/$serverCer" -alias "$clientTrustedCerAlias" -keystore "$clientPath/$clientKeystore" -storepass "$serverPassword" -noprompt Will when it runs successfully outputs: Certificate was added to keystore I tried redirecting the stdard out with: keytool ... > /dev/null But it is still printing. It appears that the message is being output into standard error. Since when I do this it is not displayed: keytool ... > /dev/null 2>&1 However this is not what I am wanting to do. I would like error messages to be output normally but I do not want "success" messages to be output to the command line. Any ideas? Whatever happened to unix convention: "If it works do not output anything".

  • Python: Which encoding is used for processing sys.argv?

    - by EOL
    What encoding are the elements of sys.argv in, in Python? are they encoded with the sys.getdefaultencoding() encoding? sys.getdefaultencoding(): Return the name of the current default string encoding used by the Unicode implementation. PS: As pointed out in some of the answers, sys.stdin.encoding would indeed be a better guess. I would love to see a definitive answer to this question, though, with pointers to solid sources! PPS: As Wim pointed out, Python 3 solves this issue by putting str objects in sys.argv (if I understand correctly). The question remains open for Python 2.x, though. Under Unix, the LC_CTYPE environment variable seems to be the correct thing to check, no? What should be done with Windows (so that sys.argv elements are correctly interpreted whatever the console)?

  • Get seconds since epoch in any POSIX compliant shell

    - by mattbh
    I'd like to know if there's a way to get the number of seconds since the UNIX epoch in any POSIX compliant shell, without resorting to non-POSIX languages like perl, or using non-POSIX extensions like GNU awk's strftime function. Here are some solutions I've already ruled out... date +%s // Doesn't work on Solaris I've seen some shell scripts suggested before, which parse the output of date then derive seconds from the formatted gregorian calendar date, but they don't seem to take details like leap seconds into account. GNU awk has the strftime function, but this isn't available in standard awk. I could write a small C program which calls the time function, but the binary would be specific to a particular architecture. Is there a cross platform way to do this using only POSIX compliant tools? I'm tempted to give up and accept a dependency on perl, which is at least widely deployed. perl -e 'print time' // Cheating (non-POSIX), but should work on most platforms

  • Explain BFS and DFS in terms of backtracking

    - by HH
    Wikipedia about DFS Depth-first search (DFS) is an algorithm for traversing or searching a tree, tree structure, or graph. One starts at the root (selecting some node as the root in the graph case) and explores as far as possible along each branch before backtracking. So is BFS? "an algorithm that choose a starting node, checks all nodes -- backtracks --, chooses the shortest path, chose neighbour nodes -- backtracks --, chose the shortest path -- finally finds the optimal path because of traversing each path due to continuos backtracking. Regex, find's pruning -- backtracking? The term backtracking confuseses due to its variety of use. UNIX find's pruning an SO-user explained with backtracking. Regex Buddy uses the term "catastrophic backtracking" if you do not limit the scope of your Regexes. It seems to be too wide umbrella-term. So: how do you define "Backtracking" GRAPH-theoretically? what is "backtracking" in BFS and DFS?

  • Writing a Windows NT subsystem

    - by Niten
    I'd like to try writing my own minimal NT subsystem on Windows 7 for purely educational purposes -- something like a bare-bones equivalent of the posix.exe in Microsoft's Subsystem for Unix-based Applications. But I can't seem to find any public documentation on this topic. What API does a subsystem need to implement? How does it get registered with Windows? How does the subsystem image need to be built (what flags need to be set in the PE header, etc.)? I'd most like to find a book or web site with an overview of the entire subject, or even the source code for a "hello world" NT subsystem that someone else has written. But anything at all would be appreciated if you can point me in the right direction here...

  • What makes good software good?

    - by Jonta
    People probably have a lot of different answers here, like good...: scalability, speed, usability, stability, consistency, completeness, absence of bugs, accessibility, documentation, code-quality and so on. There are a lot of philosophies on development of software. Like the UNIX-philosophy. Often vague and not easy to understand. I am looking for statements such as the one cited below. Which you can ask about the software when it's in the design-stage, is ready to be coded, and has been coded and is ready for launch. The software I am talking about, is of course the software made for the end-user. Ken Rockwell wrote: "I expect that it will let me get more accomplished in less time." (Here one could ask "will this let me get more accomplished in less time?")

  • Executing commands containing space in bash

    - by Epitaph
    I have a file named cmd that contains a list of unix commands as follows: hostname pwd ls /tmp cat /etc/hostname ls -la ps -ef | grep java cat cmd I have another script that executes the commands in cmd as: IFS=$'\n' clear for cmds in `cat cmd` do if [ $cmds ] ; then $cmds; echo "****************************"; fi done The problem is that commands in cmd without spaces run fine, but those with spaces are not correctly interpreted by the script. Following is the output: patrick-laptop **************************** /home/patrick/bashFiles **************************** ./prog.sh: line 6: ls /tmp: No such file or directory **************************** ./prog.sh: line 6: cat /etc/hostname: No such file or directory **************************** ./prog.sh: line 6: ls -la: command not found **************************** ./prog.sh: line 6: ps -ef | grep java: command not found **************************** ./prog.sh: line 6: cat cmd: command not found **************************** What am I missing here?

  • C++ wrapper for posix and linux specific functions

    - by Libzajc
    Hi Do you know about any good library wrapping posix and linux functions and structures ( eg. sockets or file descriptors ) into C++ classes? For example I'm thinking about a base FileDescriptor class and some inheriting classes ( unix sockets etc ) with methods like write, read or even some syscalls ( sendfile, splice ) - all throwing exceptions instead of setting errno. Or some shared memory class etc. I can't seem to find anything like that and by now I consider writing it myself, as I often have to write a C++ app for linux and either use C functions ( painful error checking ), or wrap them myself every time.

Ideally I would accomplish this task using basic unix tools like sed. Since it's not XML I can't use xmlstarlet. Could anyone please suggest recipes, so I can ideally have a script running kill-node.sh 'div class="toplinks"' *.html to prune the bits I don't want. Thank you,

  • Performance analysis strategies

    - by Bernd
    I am assigned to a performance-tuning-debugging-troubleshooting task. Scenario: a multi-application environment running on several networked machines using databases. OS is Unix, DB is Oracle. Business logic is implemented across applications using synchronous/asynchronous communication. Applications are multi-user with several hundred call center users at peak time. User interfaces are web-based. Applications are third party, I can get access to developers and source code. I only have the production system and a functional test environment, no load test environment. Problem: bad performance! I need fast results. Management is going crazy. I got symptom examples like these: user interface actions taking minutes to complete. Seaching for a customer usually takes 6 seconds but an immediate subsequent search with same parameters may take 6 minutes. What would be your strategy for finding root causes?

  • How to compare sqlite TIMESTAMP values

    - by Roel
    I have an Sqlite database in which I want to select rows of which the value in a TIMESTAMP column is before a certain date. I would think this to be simple but I can't get it done. I have tried this: SELECT * FROM logged_event WHERE logged_event.CREATED_AT < '2010-05-28 16:20:55' and various variations on it, like with the date functions. I've read http://sqlite.org/lang_datefunc.html and http://www.sqlite.org/datatypes.html and I would expect that the column would be a numeric type, and that the comparison would be done on the unix timestamp value. Apparantly not. Anyone who can help? If it matters, I'm trying this out in Sqlite Expert Personal.

  • Private VCS hosts for school projects?

    - by Ibrahim
    I want to use version control for a partner project for school, but these days it seems like there are no private, free VCS hosts that I could use. I would prefer to use git if possible, but I wouldn't mind SVN. Alternatively, if there aren't any, shouldn't there be some way for me to use git without a central repository? I don't know enough about git, but I assume that is the point of a DVCS, no? I've considered scp'ing a clone of the repository to my school unix account and then giving my partner access to that, but it seems like it would be a bit of a pain. What are your thoughts/suggestions? Edit: I do know of one site called xp-dev, but I'm not sure how much I trust it. But I could use that and use git-svn on my side, since my partner has actually only ever used svn. But still wondering if there are any alternatives.

  • File I/O OS handling

    - by Albinoswordfish
    This isn't a direct coding question but more of a OS handling mechanism. I was reading somebody's previous question regarding C# and file handling. Apparently C# was throwing an exception regarding a file being locked when trying to access this. So my question is, does C# use an internal lock to handle file I/O between processes, or does the OS use some type of mutual exclusion for file I/O? From what I learned about operating systems, well at least unix, is that the OS doesn't implement any type of mutual exclusion for processes trying to access the same file.
