  • what does "do" do here? (java)

    - by David
    I saw this bit of code on the interents somewhere. I'm wondering what thedo is for. public class LoopControl { public static void main(String[] args) { int count = 0; do { if(count % 2 == 0) { for(int j = 0; j < count; j++) { System.out.print(j+1); if(j < count-1) System.out.print(", "); } System.out.println(); } count++; } while(count <= 5); } }

  • Need help identiying a nasty rootkit in Windows

    - by goofrider
    I have a nasty rootkit that not tools seem to be able to idenity. I know for sure it's a rootkit, but I can figure out which rootkit it is. Here's what I gathered so far: It creates multiple copies of itself in %HOME%\Local Settings\Temp with names like Q.EXE, IAJARZ.exe, etc., and install them as hidden services. These EXE have SysInternals identifiers in them so they're definitely rootkits. It hooked very deep in the system, including file read/write, security policies, registry read/write, and possibly WinSock/TCP/IP. When going to Sophos.com to download their software, the rootkit inject something called Microsoft Ajax Tootkit into the page, which injects code into the email submission form in order to redirect it. (EDIT: I might have panicked. Looks like Sophos does use an AJAZ email form, their form is just broken on Chrome so it looked like a mail form injection attack, the link is http://www.sophos.com/en-us/products/free-tools/virus-removal-tool/download.aspx ) Super-Antispyware found a lot of spyware cookies, in the name of .kaspersky.2o7.net, etc. (just chedk 2o7.net, looks like it's a legit ad company) I tried comparing DNS lookup from the infected systems and from system in other physical locations, no DNS redirections it seems. I used dd to copy the MBR and compared it with the MBR provided by ms-sys package, no differences so it's not infecting MBR. No antivirus or rootkit scanner be able to identify it. Most of them can't even find it. I tried scanning, in-situ (normal mode), in safe mode, and boot to linux live CD. Scanners used: Avast, Sophos anti rootkit, Kasersky TDSSKiller, GMER, RootkitRevealer, and many others. Kaspersky reported some unsigned system files that ought to be signed (e.g. tcpip.sys), and reported a number of MD5 mismatches. But otherwise couldn't identify anything based on signature. When running Sysinternal RootkitRevealer and Sophos AntiRootkit, CPU usage goes up to 100% and gets stucked. The Rootkit is blocking them. When trying running/installing HiJackThis, RootkitRevealer and some other scanners, it tells me system security policy prevent running/installing it. The list of malicious acitivities go on and on. here's a sample of logs from all my scans. In particular, aswSnx.SYS, apnenfno.sys and PROCMON20.SYS has a huge number of hooks. It's hard to tell if the rootkit replaced legit program files like aswSnx.SYS (from Avast) and PROCMON20.SYS (from Sysinternal Process Monitor). I can't find whether apnenfno.sys is from a legit program. Help to identify it is appreciated.

  • Help me upgrade my pf.conf for OpenBSD 4.7

    - by polemon
    I'm planning on upgrading my OpenBSD to 4.7 (from 4.6) and as you may or may not know, they changed the syntax for pf.conf. This is the relevant portion from the upgrade guide: pf(4) NAT syntax change As described in more detail in this mailing list post, PF's separate nat/rdr/binat (translation) rules have been replaced with actions on regular match/filter rules. Simple rulesets may be converted like this: nat on $ext_if from 10/8 -> ($ext_if) rdr on $ext_if to ($ext_if) -> 1.2.3.4 becomes match out on $ext_if from 10/8 nat-to ($ext_if) match in on $ext_if to ($ext_if) rdr-to 1.2.3.4 and... binat on $ext_if from $web_serv_int to any -> $web_serv_ext becomes match on $ext_if from $web_serv_int to any binat-to $web_serv_ext nat-anchor and/or rdr-anchor lines, e.g. for relayd(8), ftp-proxy(8) and tftp-proxy(8), are no longer used and should be removed from pf.conf(5), leaving only the anchor lines. Translation rules relating to these and spamd(8) will need to be adjusted as appropriate. N.B.: Previously, translation rules had "stop at first match" behaviour, with binat being evaluated first, followed by nat/rdr depending on direction of the packet. Now the filter rules are subject to the usual "last match" behaviour, so care must be taken with rule ordering when converting. pf(4) route-to/reply-to syntax change The route-to, reply-to, dup-to and fastroute options in pf.conf move to filteropts; pass in on $ext_if route-to (em1 192.168.1.1) from 10.1.1.1 pass in on $ext_if reply-to (em1 192.168.1.1) to 10.1.1.1 becomes pass in on $ext_if from 10.1.1.1 route-to (em1 192.168.1.1) pass in on $ext_if to 10.1.1.1 reply-to (em1 192.168.1.1) Now, this is my current pf.conf: # $OpenBSD: pf.conf,v 1.38 2009/02/23 01:18:36 deraadt Exp $ # # See pf.conf(5) for syntax and examples; this sample ruleset uses # require-order to permit mixing of NAT/RDR and filter rules. # Remember to set net.inet.ip.forwarding=1 and/or net.inet6.ip6.forwarding=1 # in /etc/sysctl.conf if packets are to be forwarded between interfaces. ext_if="pppoe0" int_if="nfe0" int_net="192.168.0.0/24" polemon="192.168.0.10" poletopw="192.168.0.12" segatop="192.168.0.20" table <leechers> persist set loginterface $ext_if set skip on lo match on $ext_if all scrub (no-df max-mss 1440) altq on $ext_if priq bandwidth 950Kb queue {q_pri, q_hi, q_std, q_low} queue q_pri priority 15 queue q_hi priority 10 queue q_std priority 7 priq(default) queue q_low priority 0 nat-anchor "ftp-proxy/*" rdr-anchor "ftp-proxy/*" nat on $ext_if from !($ext_if) -> ($ext_if) rdr pass on $int_if proto tcp to port ftp -> 127.0.0.1 port 8021 rdr pass on $ext_if proto tcp to port 2080 -> $segatop port 80 rdr pass on $ext_if proto tcp to port 2022 -> $segatop port 22 rdr pass on $ext_if proto tcp to port 4000 -> $polemon port 4000 rdr pass on $ext_if proto tcp to port 6600 -> $polemon port 6600 anchor "ftp-proxy/*" block pass on $int_if queue(q_hi, q_pri) pass out on $ext_if queue(q_std, q_pri) pass out on $ext_if proto icmp queue q_pri pass out on $ext_if proto {tcp, udp} to any port ssh queue(q_hi, q_pri) pass out on $ext_if proto {tcp, udp} to any port http queue(q_std, q_pri) #pass out on $ext_if proto {tcp, udp} all queue(q_low, q_hi) pass out on $ext_if proto {tcp, udp} from <leechers> queue(q_low, q_std) pass in on $ext_if proto tcp to ($ext_if) port ident queue(q_hi, q_pri) pass in on $ext_if proto tcp to ($ext_if) port ssh queue(q_hi, q_pri) pass in on $ext_if proto tcp to ($ext_if) port http queue(q_hi, q_pri) pass in on $ext_if inet proto icmp all icmp-type echoreq queue q_pri If someone has experience with porting the 4.6 pf.conf to 4.7, please help me do the correct changes. OK, this is how far I've got: I commented out nat-anchor and rdr-anchor, as describted in the guide: #nat-anchor "ftp-proxy/*" #rdr-anchor "ftp-proxy/*" And this is how I've "converted" the rdr rules: #nat on $ext_if from !($ext_if) -> ($ext_if) match out on $ext_if from !($ext_if) nat-to ($ext_if) #rdr pass on $int_if proto tcp to port ftp -> 127.0.0.1 port 8021 match in on $int_if proto tcp to port ftp rdr-to 127.0.0.1 port 8021 #rdr pass on $ext_if proto tcp to port 2080 -> $segatop port 80 match in on $ext_if proto tcp tp port 2080 rdr-to $segatop port 80 #rdr pass on $ext_if proto tcp to port 2022 -> $segatop port 22 match in on $ext_if proto tcp tp port 2022 rdr-to $segatop port 22 rdr pass on $ext_if proto tcp to port 4000 -> $polemon port 4000 match in on $ext_if proto tcp tp port 4000 rdr-to $polemon port 4000 rdr pass on $ext_if proto tcp to port 6600 -> $polemon port 6600 match in on $ext_if proto tcp tp port 6600 rdr-to $polemon port 6600 Did I miss anything? Is the anchor for ftp-proxy OK as it is now? Do I need to change something in the other pass in on... lines?

  • protobuf-net NOT faster than binary serialization?

    - by Ashish Gupta
    I wrote a program to serialize a 'Person' class using XMLSerializer, BinaryFormatter and ProtoBuf. I thought protobuf-net should be faster than the other two. Protobuf serialization was faster than XMLSerialization but much slower than the binary serialization. Is my understanding incorrect? Please make me understand this. Thank you for the help.

  • JavaScript Class Patterns

    - by Liam McLennan
    To write object-oriented programs we need objects, and likely lots of them. JavaScript makes it easy to create objects: var liam = { name: "Liam", age: Number.MAX_VALUE }; But JavaScript does not provide an easy way to create similar objects. Most object-oriented languages include the idea of a class, which is a template for creating objects of the same type. From one class many similar objects can be instantiated. Many patterns have been proposed to address the absence of a class concept in JavaScript. This post will compare and contrast the most significant of them. Simple Constructor Functions Classes may be missing but JavaScript does support special constructor functions. By prefixing a call to a constructor function with the ‘new’ keyword we can tell the JavaScript runtime that we want the function to behave like a constructor and instantiate a new object containing the members defined by that function. Within a constructor function the ‘this’ keyword references the new object being created -  so a basic constructor function might be: function Person(name, age) { this.name = name; this.age = age; this.toString = function() { return this.name + " is " + age + " years old."; }; } var john = new Person("John Galt", 50); console.log(john.toString()); Note that by convention the name of a constructor function is always written in Pascal Case (the first letter of each word is capital). This is to distinguish between constructor functions and other functions. It is important that constructor functions be called with the ‘new’ keyword and that not constructor functions are not. There are two problems with the pattern constructor function pattern shown above: It makes inheritance difficult The toString() function is redefined for each new object created by the Person constructor. This is sub-optimal because the function should be shared between all of the instances of the Person type. Constructor Functions with a Prototype JavaScript functions have a special property called prototype. When an object is created by calling a JavaScript constructor all of the properties of the constructor’s prototype become available to the new object. In this way many Person objects can be created that can access the same prototype. An improved version of the above example can be written: function Person(name, age) { this.name = name; this.age = age; } Person.prototype = { toString: function() { return this.name + " is " + this.age + " years old."; } }; var john = new Person("John Galt", 50); console.log(john.toString()); In this version a single instance of the toString() function will now be shared between all Person objects. Private Members The short version is: there aren’t any. If a variable is defined, with the var keyword, within the constructor function then its scope is that function. Other functions defined within the constructor function will be able to access the private variable, but anything defined outside the constructor (such as functions on the prototype property) won’t have access to the private variable. Any variables defined on the constructor are automatically public. Some people solve this problem by prefixing properties with an underscore and then not calling those properties by convention. function Person(name, age) { this.name = name; this.age = age; } Person.prototype = { _getName: function() { return this.name; }, toString: function() { return this._getName() + " is " + this.age + " years old."; } }; var john = new Person("John Galt", 50); console.log(john.toString()); Note that the _getName() function is only private by convention – it is in fact a public function. Functional Object Construction Because of the weirdness involved in using constructor functions some JavaScript developers prefer to eschew them completely. They theorize that it is better to work with JavaScript’s functional nature than to try and force it to behave like a traditional class-oriented language. When using the functional approach objects are created by returning them from a factory function. An excellent side effect of this pattern is that variables defined with the factory function are accessible to the new object (due to closure) but are inaccessible from anywhere else. The Person example implemented using the functional object construction pattern is: var personFactory = function(name, age) { var privateVar = 7; return { toString: function() { return name + " is " + age * privateVar / privateVar + " years old."; } }; }; var john2 = personFactory("John Lennon", 40); console.log(john2.toString()); Note that the ‘new’ keyword is not used for this pattern, and that the toString() function has access to the name, age and privateVar variables because of closure. This pattern can be extended to provide inheritance and, unlike the constructor function pattern, it supports private variables. However, when working with JavaScript code bases you will find that the constructor function is more common – probably because it is a better approximation of mainstream class oriented languages like C# and Java. Inheritance Both of the above patterns can support inheritance but for now, favour composition over inheritance. Summary When JavaScript code exceeds simple browser automation object orientation can provide a powerful paradigm for controlling complexity. Both of the patterns presented in this article work – the choice is a matter of style. Only one question still remains; who is John Galt?

  • Help with hash tables and quadratic probing in Java

    - by user313458
    I really need help with inserting into a hash table. I'm just not totally getting it right now. Could someone explain quadratic and linear probing in layman's terms? public void insert(String key) { int homeLocation = 0; int location = 0; int count = 0; if (find(key).getLocation() == -1) // make sure key is not already in the table { //****** ADD YOUR CODE HERE FOR QUADRATIC PROBING ******** } } This is the code I'm working on. I'm not asking anyone to do it, I just really need help with learning the whole concept Any help would be greatly appreciated.

  • Help with parsing lxml

    - by Casey
    Hi To implement a college project, I need to handle XML files. For this I choose lxml after doing some research. However I can't seem to find some nice tutorial to help me get started. I can't choose most specifically which type of parsing I need to use. My XML files don't have that much data but speed is main concern, not memory. Can anyone point me to some tutorial that would help me or some book that I can lookup? I have already tried the tutorial on lxml site but that didn't help me much. Is there some small application I can look up to get a hang of parsing XML with lxml

  • Best calculator software to help programmers

    - by RHaguiuda
    As a embedded systems programmer I always need to make lots of base conversions (dec to hex, hex to bin and so on...), and I must admit: Windows 7 calculator is a good calc, but too limited in my point of view. I work a lot with communications protocols and it`s common to need some base conversion in this field of knowledge. I`m looking for a calculator software (not a hardware one), to help with base conversions, but it must also support scientific calc. Can anyone help on this? Since this subject is intended to help programmers, I did not ask this in SuperUser.com. Thanks.

  • Wolfram Workbench and Mathematica Help System

    - by belisarius
    I find the Wolfram Workbench a nice environment for Mathematica development. However, as I program in Mathematica, I need to navigate the Help System very often. The Workbench provides a tooltip tool that shows a very basic help for the Mma functions (just the usage messages), and is not enough for my usual needs. So: Is there a way to bring up and navigate the whole Mma Help System from inside the Workbench? Alternative solutions are also welcome. Re-entering the function name in a notebook and pressing F1 is not :)
