• Finding a integer number after a beginning t=

  - by user2966696

  I have a string like this: 33 00 4b 46 ff ff 03 10 30 t=25562 I am only interested in the five digits at the very end after the t= How can I get this numbers with a regular expression out of it? I tried grep t=..... but I also got all characters including the t= in the beginning, which I would like to drop? After finding that five digit number, I would like to divide this by 1000. So in the above mentioned case the number 25.562. Is this possible with grep and regular expressions? Thanks for your help.

• Removing a text block from a file : sed ?

  - by user555338

  Hi, Following an attack, I need to remove 4 lines of text added to .htaccess files in my site, and was thinking SED would be the way to go, but cannot see how in spire of many attempts. The added lines are RewriteEngine On RewriteCond %{HTTP_REFERER} ^http:// RewriteCond %{HTTP_REFERER} !%{HTTP_HOST} RewriteRule . http://targeturlhere.net/%{REMOTE_ADDR} I managed to create the script to remove added htaccess files containing those lines only, but for existing htaccess files in which that was appended I have to edit the file and cannot delete it. I cannot just remove line by line nor use "RewriteEngine On" as the start marker, as this instruction "RewriteEngine On" is sometimes legitimate elsewhere in the file. In most cases those lines are the last, but I guess in other files they could be in the middle, so I was trying to remove exactly that block - and have a script I could reuse in a similar case. (Edit: my 4 lines are below one another, no blank line in between but the editor here seems to either show no breakline, or one adding a blank line) Any hint or tip ? Thanks.

• Python profiler and CPU seconds

  - by dude

  Hey, I'm totally behind this topic. Yesterday I was doing profiling using Python profiler module for some script I'm working on, and the unit for time spent was a 'CPU second'. Can anyone remind me with the definition of it? For example for some profiling I got: 200.750 CPU seconds. What does that supposed to mean? At other case and for time consuming process I got: -347.977 CPU seconds, a negative number! Is there anyway I can convert that time, to calendar time? Cheers,

• Form validation in JAvascript with Regexp

  - by Nikita Barsukov

  I have a webpage with an input field where only digits are allowed. The input field has an onkeyup event that starts this validating function: function validate() { var uah_amount = document.getElementById("UAH").value; var allowed = /^\d+$/; document.getElementById("error").innerHTML = document.getElementById("UAH").value; if (!allowed.test(uah_amount)) { document.getElementById("error").style.backgroundColor = "red"; } } Everything works as I expect until I hit Backspace button to remove some characters. In this case function always behaves as if I entered letters. How to correct this?

• How to hide classes to external namespaces? Something like the package-protected modifier in Java

  - by devoured elysium

  In java is easy to "hide" classes from outside your package(namespace), as you can define them as package-protected. There seems to be no equivalent keyword modifier in C#. Is there any way I could mimic that behaviour in C#? I have a couple of classes that I really wouldn't like the rest of the assembly to know of. It is ok for classes in the same namespace to know of, but I'd like them to be hidden from the rest of the library/application. I know of the internal keyword, but that only hiddes classes if you try to access them from outside your assembly. That is not really my case, as I'd like to keep everything glued in just one .DLL/.EXE. Thanks

In this case "3", this is going to be a pagination..

• how do you group select_tag and text_field_tag?

  - by Eytan

  I'm trying to build a form where a user can select an existing category, or define their own. My form looks something like this... <%= f.select :category, category_options, prompt: "Select"> <%= f.text_field :category %> However, this UI is confusing. The user can select something in the select box, and type in a custom category. In this case, the final result is not obvious. Do you guys have any recommendations on how to handle this situation?

• Any method to denote object assignment?

  - by Droogans

  I've been studying magic methods in Python, and have been wondering if there's a way to outline the specific action of: a = MyClass(*params).method() versus: MyClass(*params).method() In the sense that, perhaps, I may want to return a list that has been split on the '\n' character, versus dumping the raw list into the variable a that keeps the '\n' intact. Is there a way to ask Python if its next action is about to return a value to a variable, and change action, if that's the case? I was thinking: class MyClass(object): def __init__(*params): self.end = self.method(*params) def __asgn__(self): return self.method(*params).split('\n') def __str__(self): """this is the fallback if __asgn__ is not called""" return self.method(*params)

• Sending some byte at time

  - by user1417815

  I'm trying to figure out way to send some amount of text from the string ech time until it reach the end of the string, example: const char* the_string = "hello world, i'm happy to meet you all. Let be friends or maybe more, but nothing less" Output: hello world Output: , i'm happy to meet you all. Output: Let be friends or maybe more Output: , but nothing less stop: no more bytes to send. the problem i have searched google, but didn't understand the examples, i spent 4 days trying find a good way, also that sendt 5 bytes at time, but in case there is less, then send them until you are at the end of the string. please help me out guys, i will accept a C or C++ way, as long it works and well explained.

• C++ Static Array Initialization - Memory Issue

  - by donalmg

  Hi, I have a header file which contains a member variable declaration of a static char array: class ABC { public: static char newArray[4]; // other variables / functions private: void setArray(int i, char * ptr); } In the CPP file, I have the array initialized to NULL: char ABC::newArray[4] = {0}; In the ABC constructor, I need to overwrite this value with a value constructed at runtime, such as the encoding of an integer: ABC::ABC() { int i; //some int value defined at runtime memset(newArray, 0, 4); // not sure if this is necessary setArray(i,newArray); } ... void setArray(int i, char * value) { // encoding i to set value[0] ... value [3] } When I return from this function, and print the modified newArray value, it prints out many more characters than the 4 specified in the array declaration. Any ideas why this is the case. I just want to set the char array to 4 characters and nothing further. Thanks...

• Model association changes in production environment, specifically converting a model to polymorphic?

  - by dustmoo

  Hi everyone, I was hoping I could get feedback on major changes to how a model works in an app that is in production already. In my case I have a model Record, that has_many PhoneNumbers. Currently it is a typical has_many belongs_to association with a record having many PhoneNumbers. Of course, I now have a feature of adding temporary, user generated records and these records will have PhoneNumbers too. I 'could' just add the user_record_id to the PhoneNumber model, but wouldn't it be better for this to be a polymorphic association? And if so, if you change how a model associates, how in the heck would I update the production database without breaking everything? .< Anyway, just looking for best practices in a situation like this. Thanks!

• SQL Server - how to determine if indexes aren't being used?

  - by rwmnau

  I have a high-demand transactional database that I think is over-indexed. Originally, it didn't have any indexes at all, so adding some for common processes made a huge difference. However, over time, we've created indexes to speed up individual queries, and some of the most popular tables have 10-15 different indexes on them, and in some cases, the indexes are only slightly different from each other, or are the same columns in a different order. Is there a straightforward way to watch database activity and tell if any indexes are not hit anymore, or what their usage percentage is? I'm concerned that indexes were created to speed up either a single daily/weekly query, or even a query that's not being run anymore, but the index still has to be kept up to date every time the data changes. In the case of the high-traffic tables, that's a dozen times/second, and I want to eliminate indexes that are weighing down data updates while providing only marginal improvement.

• Are there any real life uses for the Java byte primitive type?

  - by Thorbjørn Ravn Andersen

  For some inexplicable reason the byte primitive type is signed in Java. This mean that valid values are -128..127 instead of the usual 0..255 range representing 8 significant bits in a byte (without a sign bit). This mean that all byte manipulation code usually does integer calculations and end up masking out the last 8 bits. I was wondering if there is any real life scenario where the Java byte primitive type fits perfectly or if it is simply a completely useless design decision? EDIT: The sole actual use case was a single-byte placeholder for native code. In other words, not to be manipulated as a byte inside Java code.

• the problem of redirecting stdout in c#

  - by Mher

  Could you please explain why the shell redirection doesn't work with System.Diagnostics.Process class? I am trying to redirect the output streams to file with the following snippet: Process p = new Process(); p.StartInfo = new ProcessStartInfo(); p.StartInfo.FileName = "java.exe"; p.StartInfo.Arguments = @"> c:\Temp\test.log 2>&1"; p.StartInfo.UseShellExecute = true; p.Start(); The similar code works without problems with Python. Reading the output streams programmatically doesn't seem a preferable solution in my case because there will be a bunch of processes launched by my application.

• How can I define a one-time event so that new handlers fire (once) even after the event has already occurred?

  - by harpo

  You know how this $(function() { ... }); will fire whether or not the "document ready" event has already occurred? I want to define an event like that. That event is a special case in jQuery. I'm wondering if a custom event can behave in the same way, using only the standard event mechanisms. Ideally, I'd like to be able to define handlers in the "normal" way: $(document).on("init.mything", function() { ... }); This works now if the above runs before init.mything is triggered. But if it doesn't, then the handler never runs. What makes this tricky is, I don't want to assume anything except that jQuery has loaded. Any ideas?

• Changing UITableViewCell height on a grouped cell doesn't look good

  - by Sheehan Alam

  I have a UITableView with 3 sections. In the first section I have 2 grouped cells. I am modifying the first cell to be larger than the second. Though the first cell resizes, it seems to mess up the cell below it. How can I resolve this? - (CGFloat)tableView:(UITableView *)tblView heightForRowAtIndexPath:(NSIndexPath *)indexPath { CGFloat rowHeight; if(indexPath.section == kBioSection) { switch(indexPath.row) { case kBioSectionDescriptionRow: rowHeight = 100; break; } } else { rowHeight = 50; } return rowHeight; }

• Reflection alternative for switch on enum in order to select namespace/class

  - by Am

  Hi, I have an interface named IHarvester. There are 3 implementations of that interface, each under their own namespace: Google Yahoo Bing A HarvesterManager uses the given harvester. It knows the interface and all 3 implementations. I want some way of letting the class user say in which harvester it wants to use. And in the code select that implementation, without a switch-case implementation. Can reflection save my day? Here is the code bits: // repeat for each harvester namespace Harvester.Google { public abstract class Fetcher : BaseHarvester, IInfoHarvester {...} } public enum HarvestingSource { Google, Yahoo, Bing, } class HarvesterManager { public HarvestingSource PreferedSource {get;set;} public HarvestSomthing() { switch (PreferedSource) .... // awful... } } Thanks. I will give my 2 cents of why I want to change this. There several people writing harvesters, I want them to focus only on building more harvesters, without ever needing to update the enum, or at worst, update only the enum.

• Java Scanner - next String until a | is found

  - by user1375883

  Currently I'm trying to read through some basic cells, in this format: +-------+-------+ | | | +-------+-------+ Now I need to get the string representation of the cell's contents and send it off to another method. The problem is that the cells have no pre-defined length. I'm reading these from a file, so my easiest option should be to just use the Scanner I already have set up. Problem is, I don't really know how for this case. I have a strong feeling that I need to use the pattern somehow, but I'm at a complete loss on how to do it. I could also probably just build it up somehow, but that strikes me as being painfully slow.

• class member access specifiers and binary code

  - by pdehaan

  I understand what the typical access specifiers are, and what they mean. 'public' members are accessible anywhere, 'private' members are accessible only by the same class and friends, etc. What I'm wondering is what, if anything, this equates to in lower-level terms. Are their any post-compilation functional differences between these beyond the high-level restrictions (what can access what) imposed by the language (c++ in this case) they're used in. Another way to put it - if this were a perfect world where programmers always made good choices (like not accessing members that may change later and using only well defined members that should stay the same between implementations), would their be any reason to use these things?

• wordpress query custom fields and category

• how to dynamically (re)position an element according to the bottom of the page using JS / Jquery?

  - by jon

  Hi All, the back story: i have a tab section on a page which when navigated through displays sections (divs) of varying height. the result, is that certain inputs (which are strangely positioned for reasons i can't change) on this page reposition themselves problematically. the proposed solution: as the page height changes, have these problem inputs repositioned according to the page bottom (from which their appropriate distances are always a constant). what i'm thinking is that i need some js that does something like, page height change triggers input position from bottom to = x. there are two inputs if that's at all relevant. :) if only there was css for this (i know there is under normal circumstances, but trust me -- not in this case). thanks for your time & help i've been struggling with this for weeks!

• Difference between local and instance variables in ruby

  - by fflyer05

  I am working on a script that creates several fairly complex nested hash datastructures and then iterates through them conditionally creating database records. This is a standalone script using active record. After several minutes of running I noticed a significant lag in server responsiveness and discovered that the script, while being set to be nice +19, was enjoying a steady %85 - %90 total server memory. In this case I am using instance variables simply for readability. It helps knowing what is going to be re-used outside of the loop vs. what won't. Is there a reason to not use instance variables when they are not needed? Are there differences in memory allocation and management between local and instance variables? Would it help setting @variable = nil when its no longer needed?
