  • Buying replacement Macbook Pro Battery - Genuine vs. eBay

    - by Nicolas Webb
    I'm looking to replace my Macbook Pro's battery (15", last model before the Unibody). It's currently at 55% capacity (as reported in System Information and Battery Health Monitor). I've reset the SMC firmware, calibrated the battery, and it's just not lasting that long anymore. I've seen some genuine replacements that are "pulls" (pulled from used computers) that are rated at least 90% capacity (iFixit, MacSales). I've also seen a variety of batteries on eBay that look more like clones than genuine batteries, but are new. A new battery from Apple is $129, and when I brought my laptop in they ran the Battery test and said if I bought the battery right then they'd give me a discount (around $100). Anyone out there used one of these "OEM Compatible" batteries? Fit/finish good? (I don't want a funky color or a corner that sticks out.) Or, should I just suck it up and get the genuine replacement (for about twice the price)?

  • Windows Live Messenger replacement

    - by Mark T
    I really do not like the Windows Live Messenger interface, and every time they revise it, it gets even worse. I want to use a replacement, ... but I don't want to lose the message history. My company uses Messenger for discussion of technical problems, and I often need to visit the history to find a previous discussion. Is there any substitute client that will use/continue the message history? It must also support file transfer. I'm running Windows XP/Pro, as required by my company.

  • Java String.indexOf and empty Strings

    - by tmeisenh
    I'm curious why the String.indexOf is returning a 0 (instead of -1) when asking for the index of an empty string within a string. The Javadocs only say this method returns the index in this String of the specified string, -1 if the string isn't found. System.out.println("FOO".indexOf("")); // outputs 0 wtf!!! System.out.println("FOO".indexOf("bar")); // outputs -1 as expected System.out.println("FOO".indexOf("F")); // outputs 0 as expected System.out.println("".indexOf("")); // outputs 0 as expected, I think

  • Using string.Format for simple things?

    - by Gerrie Schenck
    In my early .Net programming days, I used string.Format() only for complex string concatenations, for example to compile strings as Problem with customer order 234 of date 2/2/2002 and payment id 55543. But now I use string.Format for almost every string concatenation I have to do, also simple ones such as prefixing a string with something. Console.WriteLine(string.Format("\t\t{0}", myString)); Is there any possible overhead on this? Maybe I should use the regular + operator to do these simple operations? What's your opinion on this?

  • Split String in C# without delimiter (sort of)

    - by Zach
    Hi, I want to split a string in C#.NET that looks like this: string Letters = "hello"; and put each letter (h, e, l, l, o) into an array or ArrayList. I have no idea what to use as the delimiter in String.Split(delimiter). I can do it if the original string has commas (or anything else): string Letters = "H,e,l,l,o"; string[] AllLettersArray = Letters.Split(",".ToCharArray()); But I have no idea what to use in a case with (supposedly) no delimiter. Is there a special character like Environment.Newline? Thanks.

  • Micro Btx Motherboard Replacement.

    - by Judy
    I got the Vundo virus that took out the mobo and hard drive on my Gateway GT5220. Is there a replacement that will work? I'm willing to keep XP. I want to fix it the cheapest way possible. The mobo is a NVIDIA GeForce 6150 AM2 microBTX with primary IDE and 4 SATA connections. I want to use a new SATA as my primary, but would like to be able to connect my old IDE drives to transfer my pictures from them to the new drive. I would appreciate any help. Thanks!

  • Parse string to create a list of element

    - by Nick
    I have a string like this: "\r color=\"red\" name=\"Jon\" \t\n depth=\"8.26\" " And I want to parse this string and create a std::list of this object: class data { std::string name; std::string value; }; Where for example: name = color value = red What is the fastest way? I can use boost. EDIT: This is what i've tried: vector<string> tokens; split(tokens, str, is_any_of(" \t\f\v\n\r")); if(tokens.size() > 1) { list<data> attr; for_each(tokens.begin(), tokens.end(), [&attr](const string& token) { if(token.empty() || !contains(token, "=")) return; vector<string> tokens; split(tokens, token, is_any_of("=")); erase_all(tokens[1], "\""); attr.push_back(data(tokens[0], tokens[1])); } ); } But it does not work if there are spaces inside " ": like color="red 1".

  • Why String.replaceAll() don't work on this String ?

    - by Aloong
    //This source is a line read from a file String src = "23570006,music,**,wu(),1,exam,\"Monday9,10(H2-301)\",1-10,score,"; //This sohuld be from a matcher.group() when Pattern.compile("\".*?\"") String group = "\"Monday9,10(H2-301)\""; src = src.replaceAll("\"", ""); group = group.replaceAll("\"", ""); String replacement = group.replaceAll(",", "#@"); System.out.println(src.contains(group)); src = src.replaceAll(group, replacement); System.out.println(group); System.out.println(replacement); System.out.println(src); I'm trying to replace the "," between \"s so I can ues String.split() latter. But the above just not working , the result is: true Monday9,10(H2-301) Monday9#@10(H2-301) 23570006,music,**,wu(),1,exam,Monday9,10(H2-301),1-10,score, but when I change the src string to String src = "123\"9,10\"123"; String group = "\"9,10\""; It works well true 9,10 9#@10 1239#@10123 What's the matter with the string???

  • Truncate portions of a string to limit the whole string's length in Ruby

    - by Horace Loeb
    Suppose you want to generate dynamic page titles that look like this: "It was all a dream, I used to read word up magazine" from "Juicy" by The Notorious B.I.G I.e., "LYRICS" from "SONG_NAME" by ARTIST However, your title can only be 69 characters total and this template will sometimes generate titles that are longer. One strategy for solving this problem is to truncate the entire string to 69 characters. However, a better approach is to truncate the less important parts of the string first. I.e., your algorithm might look something like this: Truncate the lyrics until the entire string is <= 69 characters If you still need to truncate, truncate the artist name until the entire string is <= 69 characters If you still need to truncate, truncate the song name until the entire string is <= 69 characters If all else fails, truncate the entire string to 69 characters Ideally the algorithm would also limit the amount each part of the string could be truncated. E.g., step 1 would really be "Truncate the lyrics to a minimum of 10 characters until the entire string is <= 69 characters" Since this is such a common situation, I was wondering if someone has a library or code snippet that can take care of it.

  • getting string.substring(N) not to choke when N > string.length

    - by aape
    I'm writing some code that takes a report from the mainframe and converts it to a spreadsheet. They can't edit the code on the MF to give me a delimited file, so I'm stuck dealing with it as fixed width. It's working okay now, but I need to get it more stable before I release it for testing. My problem is that in any given line of data, say it could have three columns of numbers, each five chars wide at positions 10, 16, and 22. If on this one particular row, there's no data for the last two cols, it won't be padded with spaces; rather, the length of the string will be only 14. So, I can't just blindly have dim s as string = someStream.readline a = s.substring(10, 5) b = s.substring(16, 5) c = s.substring(22, 5) because it'll choke when it substrings past the length of the string. I know I could test the length of the string before processing each row, and I have automated the filling of some of the vsariables using a counter and a loop, and using the counter*theWidthOfTheGivenVariable to jump around, but this project was a dog to start with (come on! turning a report into a spreadsheet?), but there are many different types of rows (it's not just a grid), and the code's getting ugly fast. I'd like this to be clean, clear, and maintainable for the poor sucker that gets this after me. If it matters, here's my code so far (it's really crufty at the moment). You can see some of my/its idiocy in the processSection#data subs So, I'm wondering 1) is there a way baked in to .NET to have string.substring not error when reading past the end of a string without wrapping it in a try...catch? and 2) would it be appropriate in this situation to write a new string class that inherits from string that has a more friendly substring function in it? ETA: Thanks for all the advice and knowledge everyone. I'll go with the extension. Hopefully one of these years, I'll get my chops up enough to pay someone back in kind. :)

  • String.split() method bug in GWT 2.0.3

    - by Domchi
    I'm upgrading a GWT project from GWT 1.7.1 to currently newest version 2.0.3. It seems that new GWT broke String.split(String regex) method - I get the following error on the Javascript side: this$static is undefined This happens in this line of my .nocache.js file: if (maxMatch == 0 && this$static.length > 0) { ...which happens to be a part of String split method equivalent in Javascript. Is there a cure for this, apart from doing string splitting myself?

  • String manipulation of type String substitution in mathematical expression

  • finding a string of random characters (with possible errors) within a large string of random charact

    - by mike
    I am trying to search a large string w/o spaces for a smaller string of characters. using regex I can easily find perfect matches but I can't figure out how to find partial matches. by partial matches i mean one or two extra characters in the string or one or two characters that have been changed, or one of each. the first and last characters will always match though. this would be similar to a spell checker but there are no spaces and the strings dont contain actual words, just random hex digits. i figured a way to find the string if there are no extra characters using indexOf(string.charAt(0)) and indexOf(charAt(string.length()-1) and looping through the characters between the two indexes. but this can be problematic when dealing with randomized characters because of the possibility of finding the first and last characters at the correct spacing but none of the middle characters matching. i've been scratching my head for hours on this issue. any ideas?

  • Java string too long?

    - by wrongusername
    I have the following code in Java (which worked just fine in C++ for some reason) which produces an error: int a; System.out.println("String length: " + input.length()); for(a = 0; ((a + 1) * 97) < input.length(); a++) { System.out.print("Substring at " + a + ": "); System.out.println(input.substring(a * 97, 97)); //other code here... } Output: String length: 340 Substring at 0: HelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHe Substring at 1: Exception in thread "AWT-EventQueue-0" java.lang.StringIndexOutOfBoundsException: String index out of range: -97 //long list of "at ..." stuff Substring at 2: Using a string of length 200, however, the following output is produced: String length: 200 Substring at 0: HelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHe Substring at 1: That is it; no exceptions raised, just... nothing. What is happening here?

  • Iterating through String word at a time in Python

    - by AlgoMan
    I have a string buffer of a huge text file. I have to search a given words/phrases in the string buffer. Whats the efficient way to do it ? I tried using re module matches. But As i have a huge text corpus that i have to search through. This is taking large amount of time. Given a Dictionary of words and Phrases. I iterate through the each file, read that into string , search all the words and phrases in the dictionary and increment the count in the dictionary if the keys are found. One small optimization that we thought was to sort the dictionary of phrases/words with the max number of words to lowest. And then compare each word start position from the string buffer and compare the list of words. If one phrase is found, we don search for the other phrases (as it matched the longest phrase ,which is what we want) Can some one suggest how to go about word by word in the string buffer. (Iterate string buffer word by word) ? Also, Is there any other optimization that can be done on this ?

  • string.format vs + for string concatenatoin

    - by AMissico
    Which is better in respect to performance and memory utilization? // + Operator oMessage.Subject = "Agreement, # " + sNumber + ", Name: " + sName; // String.Format oMessage.Subject = string.Format("Agreement, # {0}, Name: {1}", sNumber, sName); My preference is memory utilization. The + operator is used throughout the application. String.Format and StringBuilder is rarely use. I want to reduce the amount of memory fragmentation caused by excessive string allocations.

  • Is On-The-Fly string replacement possible using GreaseMonkey and Firefox

    - by Gary M. Mugford
    I have looked for means to stop Brightcove videos from autostarting in Firefox and have come to the conclusion it isn't possible without external programming via something like Grease Monkey. However, I'm not proficient in javascript let alone GM. So I thought I'd ask here first whether what I want to do is feasible, or whether it's a fool's errand. What I want to accomplish is have a site specific script executed to replace a string value on the run in that site's code. Specifically, what I am looking for is something GM-style that would do this: if site_domain = 'www.SiteWithAutoPlayVideos.com' then replace_all('<param name="autoStart" value="true" />', '<param name="autoStart" value="false" />'); Having looked through Super User for anything GreaseMonkey that might relate, I see notices that the sandbox GM executes scripts in has to remain separate for security reasons. So, I suspect I might be in for disappointment. BUT if it is accomplishable and somebody here can confirm it, then I will do my best to struggle through the learning curve and get this noisome little problem put to rest. Yes, I have tried Flash Block and FlashDisable in order to attack this issue with no avail. Thanks in advance for your time.

  • How to compare two structure strings in C++

    - by Arvandor
    Ok, so this week in class we're working with arrays. I've got an assignment that wanted me to create a structure for an employee containing an employee ID, first name, last name, and wages. Then it has me ask users for input for 5 different employees all stored in an array of this structure, then ask them for a search field type, then a search value. Lastly, display all the information for all positive search results. I'm still new, so I'm sure it isn't a terribly elegant program, but what I'm trying to do now is figure out how to compare a user entered string with the string stored in the structure... I'll try to give all the pertinent code below. struct employee { int empid, string firstname, string lastname, float wage }; employee emparray[] = {}; employee value[] = {}; //Code for populating emparray and structure, then determine search field etc. cout << "Enter a search value: "; cin >> value.lastname; for(i = 0; i < 5; i++) { if(strcmp(value.lastname.c_str, emparray[i].lastname.c_str) == 0) { output(); } } Which... I thought would work, but it's giving me the following error.. Error 1 error C3867: 'std::basic_string<_Elem,_Traits,_Alloc>::c_str': function call missing argument list; use '&std::basic_string<_Elem,_Traits,_Alloc>::c_str' to create a pointer to member d:\myfile Any thoughts on what's going on? Is there a way to compare two .name notated strings without totally revamping the program? IF you want to drill me on best practices, please feel free, but also please try to solve my particular problem.

  • How to convert a JSON string to a Map<String, String> with Jackson JSON

    - by Infinity
    This is my first time trying to do something useful with Java.. I'm trying to do something like this but it doesn't work: Map<String, String> propertyMap = new HashMap<String, String>(); propertyMap = JacksonUtils.fromJSON(properties, Map.class); But the IDE says: 'Unchecked assignment Map to Map<String,String>' What's the right way to do this? I'm only using Jackson because that's what is already available in the project, is there a native Java way of converting to/from JSON? In PHP I would simply json_decode($str) and I'd get back an array. I need basically the same thing here. Thanks!
